| Abbey Capital Futures Strategy Fund | Commodity Sector Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Commodity Sector Risk: Exposure to the commodities markets may subject the Fund to greater volatility than investments in traditional securities. The value of commodity-linked derivative instruments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, pandemics, embargoes or other trade barriers, tariffs and international economic, political and regulatory developments. The prices of energy, industrial metals, precious metals, agriculture and livestock sector commodities may fluctuate widely due to factors such as changes in value, supply and demand and governmental regulatory policies. The commodity-linked securities in which the Fund invests may be issued by companies in the financial services sector, and events affecting the financial services sector may cause the Fund’s Share value to fluctuate.
|
| Abbey Capital Futures Strategy Fund | Counterparty Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Counterparty Risk: Counterparty risk is the risk that the other party(s) to an agreement or a participant to a transaction, such as a broker or the futures commission merchant, might default on a contract or fail to perform by failing to pay amounts due or failing to fulfill the obligations of the contract or transaction.
|
| Abbey Capital Futures Strategy Fund | Credit Risk [Member] |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Credit Risk: Credit risk refers to the possibility that the issuer of the security will not be able to make principal and interest payments when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. Securities
rated in the four highest categories by the rating agencies are considered investment grade but they may also have some speculative characteristics. Investment grade ratings do not guarantee that bonds will not lose value or default. In addition, the credit quality of securities may be lowered if an issuer’s financial condition changes. The Fund could also be delayed or hindered in its enforcement of rights against an issuer, guarantor, or counterparty.
|
| Abbey Capital Futures Strategy Fund | Currency Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Currency Risk: Investment in foreign securities also involves currency risk associated with securities that trade or are denominated in currencies other than the U.S. dollar and which may be affected by fluctuations in currency exchange rates. An increase in the strength of the U.S. dollar relative to a foreign currency may cause the U.S. dollar value of an investment in that country to decline. Foreign currencies also are subject to risks caused by inflation, interest rates, budget deficits and low savings rates, political factors and government controls. Forward foreign currency exchange contracts may limit potential gains from a favorable change in value between the U.S. dollar and foreign currencies. Unanticipated changes in currency pricing may result in poorer overall performance for the Fund than if it had not engaged in these contracts.
|
| Abbey Capital Futures Strategy Fund | Cyber Security Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Cyber Security Risk: Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.
|
| Abbey Capital Futures Strategy Fund | Derivatives Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Derivatives Risk: The Fund’s investments in derivative instruments including options, forward currency exchange contracts, swaps and futures, which may be leveraged, may result in losses. Investments in derivative instruments may result in losses exceeding the amounts invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments. The use of derivatives is also subject to operational and legal risks. Operational risks generally refer to risks related to potential operational issues, including documentation issues, settlement issues, system failures, inadequate controls and human error. Legal risks generally refer to risks of loss resulting from insufficient documentation, insufficient capacity or authority of a counterparty, or legality or enforceability of a contract.
|
| Abbey Capital Futures Strategy Fund | Emerging Markets Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Emerging Markets Risk: Investment in emerging market securities involves greater risk than that associated with investment in foreign securities of developed foreign countries. These risks include volatile currency exchange rates, periods of high inflation, increased risk of default, greater social, economic and political uncertainty and instability, less governmental supervision and regulation of securities markets, weaker auditing and financial reporting standards, lack of liquidity in the markets, and the significantly smaller market capitalizations of emerging market issuers. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets. In addition, investments in certain emerging markets are subject to an elevated risk of loss resulting from market manipulation and the imposition of exchange controls (including repatriation restrictions). The legal rights and remedies available for investors in emerging markets may be more limited than the rights and remedies available in the U.S., and the ability of U.S. authorities (e.g., SEC and the U.S. Department of Justice) to bring actions against bad actors in emerging markets may be limited.
|
| Abbey Capital Futures Strategy Fund | Fixed Income Securities Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Fixed Income Securities Risk: Fixed income securities in which the Fund may invest are subject to certain risks, including: interest rate risk, prepayment risk and credit/default risk. Interest rate risk involves the risk that prices of fixed income securities will rise and fall in response to interest rate changes. Prepayment risk involves the risk that in declining interest rate environments prepayments of principal could increase and require the Fund to reinvest proceeds of the prepayments at lower interest rates. Credit risk involves the risk that the credit rating of a security may be lowered.
|
| Abbey Capital Futures Strategy Fund | Foreign Investments Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Foreign Investments Risk: International investing may be subject to special risks, including currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and other financial practices. The Fund may invest in securities of foreign issuers either directly or through depositary receipts. Depositary receipts may be available through “sponsored” or “unsponsored” facilities. Holders of unsponsored depositary receipts generally bear all of the costs of the unsponsored facility. The depository of an unsponsored facility is frequently under no obligation to distribute shareholder communications received from the issuer of the deposited security or to pass through, to the holders of the receipts, voting rights with respect to the deposited securities. The depository of unsponsored depositary receipts may provide less information to receipt holders. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its net asset value (“NAV”). Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.
|
| Abbey Capital Futures Strategy Fund | Forward and Futures Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Forward and Futures Risk: The successful use of forward and futures contracts draws upon the Adviser’s and Trading Advisers’ skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of futures contracts are (a) the imperfect correlation between the change in market value of instruments held by the Fund and the price of the forward or futures contract; (b) possible lack of a liquid secondary market, and possible regulatory position limits and restrictions, for a forward or futures contract and the resulting inability to close a forward or futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the Advisers and Trading Advisers’ inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; (e) the possibility that the counterparty will default in the performance of its obligations; and (f) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so.
|
| Abbey Capital Futures Strategy Fund | Government Intervention and Regulatory Changes |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Government Intervention and Regulatory Changes: The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) (which was passed into law in July 2010) significantly revised and expanded the rulemaking, supervisory and enforcement authority of federal bank, securities and commodities regulators. There can be no assurance that future regulatory actions including, but not limited to, those authorized by the Dodd-Frank Act will not adversely impact the Fund. Major changes resulting from legislative or regulatory actions could materially affect the profitability of the Fund or the value of investments made by the Fund or force the Fund to revise its investment strategy or divest certain of its investments. Any of these developments could expose the Fund to additional costs, taxes, liabilities, enforcement actions and reputational risk.
In addition, Rule 18f-4 under the 1940 Act provides for the regulation of a registered investment company’s use of derivatives and certain related investments. Rule 18f-4 imposes limits on the amount of derivatives a fund can enter into, treats derivatives as senior securities so that a failure to comply with the limits would result in a statutory violation, and requires the Fund to establish and maintain a comprehensive derivatives risk management program and appoint a derivatives risk manager. The Fund has adopted procedures for investing in derivatives and other transactions in compliance with Rule 18f-4.
|
| Abbey Capital Futures Strategy Fund | Hedging Transactions Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Hedging Transactions Risk: The Adviser and Trading Advisers from time to time employ various hedging techniques. The success of the Fund’s hedging strategy will be subject to the Adviser’s and Trading Advisers’ ability to correctly assess the degree of correlation between the performance of the instruments used in the hedging strategy and the performance of the investments in the portfolio being hedged. Since the characteristics of many securities change as markets change or time passes, the success of the Fund’s hedging strategy will also be subject to the Adviser’s and Trading Advisers’ ability to continually recalculate, readjust, and execute hedges in an efficient and timely manner. For a variety of reasons, the Adviser and Trading Advisers may not seek to establish a perfect correlation between such hedging instruments and the portfolio holdings being hedged. Such imperfect correlation may prevent the Fund from achieving the intended hedge or expose the Fund to risk of loss. In addition, it is not possible to hedge fully or perfectly against any risk, and hedging entails its own cost.
|
| Abbey Capital Futures Strategy Fund | High Portfolio Turnover Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● High Portfolio Turnover Risk: The risk that when investing on a shorter-term basis, the Fund may as a result trade more frequently and incur higher levels of brokerage fees and commissions, and cause higher levels of current tax liability to shareholders in the Fund.
|
| Abbey Capital Futures Strategy Fund | Interest Rate Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Interest Rate Risk: Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short term or long term interest rates rise sharply or otherwise change in a manner not anticipated by the Adviser and Trading Advisers. Changing interest rates may have unpredictable effects on the markets and the Fund’s investments and may also affect the liquidity of fixed income securities and instruments held by the Fund. Declines in interest rate levels could cause the Fund’s earnings to fall below the Fund’s expense ratio, resulting in a negative yield, and a decline in the Fund’s share price. A general rise in interest rates may cause investors to move out of fixed income securities on a large scale, which could adversely affect the price and liquidity of fixed income securities and could also result in increased redemptions for the Fund. Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund. Certain countries and regulatory bodies may use negative interest rates as a monetary policy tool to encourage economic growth during periods of deflation. In a negative interest rate environment, debt instruments may trade at negative yields, which means the purchaser of the instrument may receive at maturity less than the total amount invested. Interest rates in the United States and many other countries have risen in recent periods and may continue to remain elevated for the foreseeable future. In the case of the United States, longer-term inflationary pressure may result from the U.S. government’s fiscal policies and the Fund may experience higher interest rates over its investment horizon.
|
| Abbey Capital Futures Strategy Fund | Leveraging Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Leveraging Risk: Investments in derivative instruments may give rise to a form of leverage. Trading Advisers may engage in speculative transactions which involve substantial risk and leverage, such as making short sales. The use of leverage by the Adviser and Trading Advisers may increase the volatility of the Fund. These leveraged instruments may result in losses to the Fund or may adversely affect the Fund’s NAV or total return, because instruments that contain leverage are more sensitive to changes in interest rates. The Fund may also have to sell assets at inopportune times to satisfy its obligations in connection with such transactions.
|
| Abbey Capital Futures Strategy Fund | Management Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Management Risk: The Fund is subject to the risk of poor investment selection. In other words, the individual investments of the Fund may not perform as well as expected, and/or the Fund’s portfolio management practices may not work to achieve their desired result.
|
| Abbey Capital Futures Strategy Fund | Market Risk |

● Manager Risk: If the Adviser and Trading Advisers make poor investment decisions, it will negatively affect the Fund’s investment performance.
|
| Abbey Capital Futures Strategy Fund | Market Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Market Risk: The NAV of the Fund will change with changes in the market value of its portfolio positions. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Investors may lose money.
|
| Abbey Capital Futures Strategy Fund | Multi-Manager Dependence Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Multi-Manager Dependence Risk: The success of the Fund’s investment strategy depends both on the Adviser’s ability to select Trading Advisers and to allocate assets to those Trading Advisers and on each Trading Adviser’s ability to execute the relevant strategy and select investments for the Fund and the Subsidiaries. The Trading Advisers’ investment styles may not always be complementary, which could adversely affect the performance of the Fund.
|
| Abbey Capital Futures Strategy Fund | New Adviser Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● New Adviser Risk: The Trading Advisers may be newly registered or not registered with the SEC and/or have not previously managed a mutual fund. Accordingly, investors in the Fund bear the risk that a Trading Adviser’s inexperience may limit its effectiveness.
|
| Abbey Capital Futures Strategy Fund | Options Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Options Risk: Purchasing and writing put and call options are highly specialized activities and entail greater than ordinary investment risks. The Fund may not fully benefit from or may lose money on an option if changes in its value do not correspond as anticipated to changes in the value of the underlying securities.
|
| Abbey Capital Futures Strategy Fund | Quantitative Trading Strategies Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Quantitative Trading Strategies Risk: The Adviser and Trading Advisers may use quantitative methods to select investments. Securities or other investments selected using quantitative methods may perform differently from the market as a whole or from their expected performance for many reasons, including factors used in building the quantitative analytical framework, the weights placed on each factor, and changing sources of market returns, among others. Any errors or imperfections in quantitative
analyses or models, or in the data on which they are based, could adversely affect the ability of the Adviser or a Trading Adviser to use such analyses or models effectively, which in turn could adversely affect the Fund’s performance. There can be no assurance that these methodologies will help the Fund to achieve its investment objective.
|
| Abbey Capital Futures Strategy Fund | Short Sales Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Short Sales Risk: Short sales of securities may result in gains if a security’s price declines, but may result in losses if a security’s price rises. In a rising market, short positions may be more likely to result in losses because securities sold short may be more likely to increase in value. Short selling also involves the risks of: increased leverage, and its accompanying potential for losses; the potential inability to reacquire a security in a timely manner, or at an acceptable price; the possibility of the lender terminating the loan at any time, forcing the Fund to close the transaction under unfavorable circumstances; and the additional costs that may be incurred. The Fund may engage in short sales that are either “uncovered” or “against the box.” A short sale is “against the box” if at all times during which the short position is open, the Fund owns at least an equal amount of the securities or securities convertible into, or exchangeable without further consideration for, securities of the same issue as the securities that are sold short. Short sales “against the box” may protect the Fund against the risk of losses in the value of a portfolio security because any decline in value of the security should be wholly or partially offset by a corresponding gain in the short position. Any potential gains in the security, however, would be wholly or partially offset by a corresponding loss in the short position. Short sales that are not “against the box” involve a form of investment leverage, and the amount of the Fund’s loss on a short sale is potentially unlimited.
|
| Abbey Capital Futures Strategy Fund | Subsidiary Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Subsidiary Risk: By investing in the Subsidiaries, the Fund is indirectly exposed to the risks associated with each Subsidiary’s investments. The derivatives and other investments held by the Subsidiaries are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held directly by the Fund. The Subsidiaries are not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, are not subject to all the investor protections of the 1940 Act. Changes in the laws or acts of the United States, Delaware and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiaries to continue to operate as they currently do and could adversely affect the Fund.
|
| Abbey Capital Futures Strategy Fund | Tax Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Tax Risk: In order to qualify as a RIC, the Fund must meet certain requirements regarding the source of its income, the diversification of its assets and the distribution of its income. Under the test regarding the source of a RIC’s income, at least 90% of the gross income of the RIC each year must be qualifying income, which consists of dividends, interest, gains on investment assets and other categories of investment income. Treasury Regulations provide that income from a foreign subsidiary that is a controlled foreign corporation is qualifying income for purposes of the Fund remaining qualified as a RIC for U.S. federal income tax purposes. Notwithstanding the treatment of controlled foreign corporations in the regulations, the Internal Revenue Service (“IRS”) may take the position that income earned by the Fund through the Cayman Subsidiary may not be qualifying income because of its investment in commodities. Additionally, the IRS may take the position that certain commodity-linked structured notes may not be qualifying income. A recharacterization of income from the Cayman Subsidiary or commodity-linked structured notes could cause the Fund to fail to qualify as a RIC. If the Fund were to fail to qualify as a RIC and became subject to federal income tax, shareholders of the Fund would be subject to diminished returns. Changes in the laws or acts of the United States, Delaware and/or the Cayman Islands could result in the inability of the Fund and/or its Subsidiaries to operate as described in this Prospectus and the SAI and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax or withholding tax on the Cayman Subsidiary or the SPC. If Cayman Islands act changes such that the Cayman Subsidiary and/or the SPC must pay Cayman Islands taxes, Fund shareholders would likely suffer decreased investment returns.

● Non-Diversification Risk: The Fund is non-diversified. Compared to other funds, the Fund may invest more of its assets in a smaller number of companies. Gains or losses on a single stock may have greater impact on the Fund.

● Commodity Sector Risk: Exposure to the commodities markets may subject the Fund to greater volatility than investments in traditional securities. The value of commodity-linked derivative instruments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, pandemics, embargoes or other trade barriers, tariffs and international economic, political and regulatory developments. The prices of energy, industrial metals, precious metals, agriculture and livestock
sector commodities may fluctuate widely due to factors such as changes in value, supply and demand and governmental regulatory policies. The commodity-linked securities in which the Fund invests may be issued by companies in the financial services sector, and events affecting the financial services sector may cause the Fund’s Share value to fluctuate.

The Fund and its Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

● Forward and Futures Risk: The successful use of forward and futures contracts draws upon the Adviser’s and Trading Advisers’ skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of futures contracts are (a) the imperfect correlation between the change in market value of instruments held by the Fund and the price of the forward or futures contract; (b) possible lack of a liquid secondary market, and possible regulatory position limits and restrictions, for a forward or futures contract and the resulting inability to close a forward or futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the Adviser’s and Trading Advisers’ inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; (e) the possibility that the counterparty will default in the performance of its obligations; and (f) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so.

| ABBEY CAPITAL MULTI ASSET FUND | Hedging Transactions Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Hedging Transactions Risk: The Adviser and Trading Advisers from time to time employ various hedging techniques. The success of the Fund’s hedging strategy will be subject to the Adviser’s and Trading Advisers’ ability to correctly assess the degree of correlation between the performance of the instruments used in the hedging strategy and the performance of the investments in the portfolio being hedged. Since the characteristics of many securities change as markets change or time passes, the success of the Fund’s hedging strategy will also be subject to the Adviser’s and Trading Advisers’ ability to continually recalculate, readjust, and execute hedges in an efficient and timely manner. For a variety of reasons, the Adviser and Trading Advisers may not seek to establish a perfect correlation between such hedging instruments and the portfolio holdings being hedged. Such imperfect correlation may prevent the Fund from achieving the intended hedge or expose the Fund to risk of loss. In addition, it is not possible to hedge fully or perfectly against any risk, and hedging entails its own cost.

● High Portfolio Turnover Risk: The risk that when investing on a shorter-term basis, the Fund may as a result trade more frequently and incur higher levels of brokerage fees and commissions, and cause higher levels of current tax liability to shareholders in the Fund.

● Interest Rate Risk: Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short term or long term interest rates rise sharply or otherwise change in a manner not anticipated by the Adviser and Trading Advisers. Changing interest rates may have unpredictable effects on the markets and the Fund’s investments and may also affect the liquidity of fixed income securities and instruments held by the Fund. Declines in interest rate levels could cause the Fund’s earnings to fall below the Fund’s expense ratio, resulting in a negative yield, and a decline in the Fund’s share price. A general rise in interest rates may cause investors to move out of fixed income securities on a large scale, which could adversely affect the price and liquidity of fixed income securities and could also result in increased redemptions for the Fund. Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund. Certain countries and regulatory bodies may use negative interest rates as a monetary policy tool to encourage economic growth during periods of deflation. In a negative interest rate environment, debt instruments may trade at negative yields, which means the purchaser of the instrument may receive at maturity less than the total amount invested. Interest rates in the United States and many other countries have risen in recent periods and may continue to remain elevated for the foreseeable future. In the case of the United States, longer-term inflationary pressure may result from the U.S. government’s fiscal policies and the Fund may experience higher interest rates over its investment horizon.

| Risk [Text Block] |
● Leveraging Risk: Investments in derivative instruments may give rise to a form of leverage. Trading Advisers may engage in speculative transactions which involve substantial risk and leverage, such as making short sales. The use of leverage by the Adviser and Trading Advisers may increase the volatility of the Fund. These leveraged instruments may result in losses to the Fund or may adversely affect the Fund’s NAV or total return, because instruments that contain leverage are more sensitive to changes in interest rates. The Fund may also have to sell assets at inopportune times to satisfy its obligations in connection with such transactions.

● Multi-Manager Dependence Risk: The success of the Fund’s investment strategy depends both on the Adviser’s ability to select Trading Advisers and to allocate assets to those Trading Advisers and on each Trading Adviser’s ability to execute the relevant strategy and select investments for the Fund and each Subsidiary. The Trading Advisers’ investment styles may not always be complementary, which could adversely affect the performance of the Fund.

● Quantitative Trading Strategies Risk: The Adviser and Trading Advisers may use quantitative methods to select investments. Securities or other investments selected using quantitative methods may perform differently from the market as a whole or from their expected performance for many reasons, including factors used in building the quantitative analytical framework, the weights placed on each factor, and changing sources of market returns, among others. Any errors or imperfections in quantitative analyses or models, or in the data on which they are based, could adversely affect the ability of the Adviser or a Trading Adviser to use such analyses or models effectively, which in turn could adversely affect the Fund’s performance. There can be no assurance that these methodologies will help the Fund to achieve its investment objective.

|

● Subsidiary Risk: By investing in the Subsidiaries, the Fund is indirectly exposed to the risks associated with each Subsidiary’s investments. The derivatives and other investments held by the Subsidiaries are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held directly by the Fund. The Subsidiaries are not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, are not subject to all the investor protections of the 1940 Act. Changes in the laws or acts of the United States, Delaware and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiaries to continue to operate as they currently do and could adversely affect the Fund.
|
| ABBEY CAPITAL MULTI ASSET FUND | Tax Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Tax Risk: In order to qualify as a RIC, the Fund must meet certain requirements regarding the source of its income, the diversification of its assets and the distribution of its income. Under the test regarding the source of a RIC’s income, at least 90% of the gross income of the RIC each year must be qualifying income, which consists of dividends, interest, gains on investment assets and other categories of investment income. Treasury Regulations provide that income from a foreign subsidiary that is a controlled foreign corporation is qualifying income for purposes of the Fund remaining qualified as a RIC for U.S. federal income tax purposes. Notwithstanding the treatment of controlled foreign corporations in the regulations, the Internal Revenue Service (“IRS”) may take the position that income earned by the Fund through the Cayman
Subsidiary may not be qualifying income because of its investment in commodities. Additionally, the IRS may take the position that certain commodity-linked structured notes may not be qualifying income. A recharacterization of income from the Cayman Subsidiary or commodity-linked structured notes could cause the Fund to fail to qualify as a RIC. If the Fund were to fail to qualify as a RIC and became subject to federal income tax, shareholders of the Fund would be subject to diminished returns. Changes in the laws or acts of the United States, Delaware and/or the Cayman Islands could result in the inability of the Fund and/or its Subsidiaries to operate as described in this Prospectus and the SAI and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax or withholding tax on the Cayman Subsidiary or the SPC. If Cayman Islands act changes such that the Cayman Subsidiary and/or the SPC must pay Cayman Islands taxes, Fund shareholders would likely suffer decreased investment returns.

● Equity and Equity-Related Securities Risk: Investments in equity securities and equity derivatives in general are subject to market risks that may cause their prices to fluctuate over time. The value of a convertible security may not increase or decrease as rapidly as the underlying common stock. Common stocks may decline over short or even extended periods of time. The purchase of rights or warrants involves the risk that the Fund could lose the purchase value of a right or warrant if the right to subscribe to additional shares is not executed prior to the right’s or warrant’s expiration. The value of securities convertible into equity securities, such as warrants or convertible debt, is also affected by prevailing interest rates, the credit quality of the issuer and any call provision.

| ABBEY CAPITAL MULTI ASSET FUND | Government Intervention and Regulatory Changes Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
● Government Intervention and Regulatory Changes: The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) (which was passed into law in July 2010) significantly revised and expanded the rulemaking, supervisory and enforcement authority of federal bank, securities and commodities regulators. There can be no assurance that future regulatory actions including, but not limited to, those authorized by the Dodd-Frank Act will not adversely impact the Fund. Major changes resulting from legislative or regulatory actions could materially affect the profitability of the Fund or the value of investments made by the Fund or force the Fund to revise its investment strategy or divest certain of its investments. Any of these developments could expose the Fund to additional costs, taxes, liabilities, enforcement actions and reputational risk.
In addition, Rule 18f-4 under the 1940 Act provides for the regulation of a registered investment company’s use of derivatives and certain related investments. Rule 18f-4 imposes limits on the amount of derivatives a fund can enter into, treats derivatives as senior securities so that a failure to comply
with the limits would result in a statutory violation, and requires the Fund to establish and maintain a comprehensive derivatives risk management program and appoint a derivatives risk manager. The Fund has adopted procedures for investing in derivatives and other transactions in compliance with Rule 18f-4.

● Other Investment Companies Risk: To the extent the Fund invests in other investment companies, including money market funds and ETFs, its performance will be affected by the performance of those other investment companies. Investments in other investment companies are subject to the risks of the other investment companies’ investments, as well as to the other investment companies’ expenses. In addition to risks generally associated with investments in investment company securities, ETFs are subject to the following risks that do not apply to traditional mutual funds: (i) an ETF’s shares may trade at a market price that is above or below their net asset value (“NAV”); (ii) an active trading market for an ETF’s shares may not develop or be maintained; (iii) the ETF may employ an investment strategy that utilizes high leverage ratios; or (iv) trading of an ETF’s shares may be halted if the listing exchange’s officials deem such action appropriate, the shares are de-listed from the exchange, or the activation of market-wide “circuit breakers” (which are tied to large decreases in stock prices) halts stock trading generally. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their NAV.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

Convertible Securities Risk. Securities that can be converted into common stock, such as certain securities and preferred stock, are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk.

Equity Securities Risk. The Fund is designed for investors who can accept the risks of investing in a portfolio with significant holdings of equity securities.

Growth Stock Risk. Growth stocks are typically priced higher than other stocks, in relation to earnings and other measures, because investors believe they have more growth potential. This potential may or may not be realized and, if it is not realized, may result in a loss to the Fund. Growth stock prices also tend to be more volatile than the overall market. Because different types of stocks go out of favor with investors depending on market and economic conditions, the Fund’s return may be adversely affected during a market downturn and when growth stocks are out of favor.

Illiquid Securities Risk. Investing in illiquid securities is subject to certain risks, such as limitations on resale and uncertainty in determining valuation. Limitations on resale may adversely affect the marketability of portfolio securities and the Fund might be unable to dispose of restricted or other illiquid securities promptly or at reasonable prices and might thereby experience difficulty satisfying redemptions within seven days. The Fund might, in order to dispose of restricted securities, have to register securities resulting in additional expense and delay. Adverse market conditions could impede such a public offering of such securities. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
|
●
|
IPO Risk. IPO risk is the risk that the market value of IPO shares will fluctuate considerably due to certain factors, such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about the issuer. The purchase of IPO shares may involve high transaction costs. IPO shares are subject to market risk and liquidity risk. When the Fund’s asset base is small, a significant portion of the Fund’s performance could be attributable to investments in IPOs, because such investments would have a magnified impact on the Fund. As the Fund’s assets grow, the effect of the Fund’s investments in IPOs on the Fund’s performance will likely decline, which could reduce the Fund’s performance. Because of the price volatility of IPO shares, the Fund may choose to hold IPO shares for a very short period of time. This may increase the turnover of the Fund’s portfolio and may lead to increased expenses to the Fund, such as commissions and transaction costs. In addition, the Adviser cannot guarantee continued access to IPOs.

|
Portfolio Turnover Risk. The Adviser and Sub-Advisers will not consider portfolio turnover rate a limiting factor in making investment decisions consistent with the Fund’s investment objective and policies. Therefore, it is possible that the Fund may experience high rates of portfolio turnover. High portfolio turnover will cause the Fund to incur higher brokerage commissions and transaction costs, which could lower the Fund’s performance. In addition to lower performance, high portfolio turnover could result in taxable capital gains. A portfolio turnover rate of 100% is considered to be high.

|
REIT Risk. REITs may be affected by economic forces and other factors related to the real estate industry. The value of securities issued by REITs is affected by tax and regulatory requirements and by perceptions of management skill. They also may be affected by general economic conditions and are subject to heavy cash flow dependency, defaults by borrowers or tenants, self-liquidation at an economically disadvantageous time, and the possibility of failing to qualify for favorable tax treatment under applicable U.S. or foreign law and/or to maintain exempt status under the Investment Company Act of 1940, as amended (the “1940 Act”). Additional risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self liquidation, interest rate risks (especially mortgage REITS) and liquidity risks. REITs that invest in real estate mortgages are also subject to prepayment risk. Investing in REITs may involve risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume, engage in dilutive offerings, and may be subject to more abrupt or erratic price movements than larger company securities. Historically, small capitalization stocks, such as REITs, have been more volatile in price than the larger capitalization stocks included in the S&P 500® Index. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law, or (ii) maintain their exemptions from registration under the 1940 Act. The Fund will indirectly bear its proportionate share of any expenses, including management fees, paid by an externally managed REIT in which it invests.

|
●
|
Small and Micro-Cap Risk. The securities of small and micro-cap companies may be more volatile in price, have wider spreads between their bid and ask prices, and have significantly lower trading volumes than the securities of larger capitalization companies. As a result, the purchase or sale of more than a limited number of shares of the securities of a smaller company may affect its market price. The Fund may need a considerable amount of time to purchase or sell its positions in these securities. Some small and micro-cap companies are followed by few, if any, securities analysts, and there tends to be less publicly available information about such companies. The small and micro-cap securities in which the Fund invests may be traded only in the over-the-counter market or on a regional securities exchange, may be listed only in the quotation service commonly known as the “pink sheets,” and may not be traded every day or in the volume typical of trading on a national securities exchange. They generally have even more limited trading volumes and are subject to even more abrupt or erratic market price movements than are mid and large cap securities, and the Fund may be able to deal with only a few market-makers when purchasing and selling securities. Small and micro-cap companies also may have limited markets, financial resources or product lines, may lack management depth, and may be more vulnerable to adverse business or market developments. Smaller company stocks may fall out of favor relative to mid or large cap stocks, which may cause the Fund to underperform other equity funds that focus on mid or large cap stocks. Moreover, the lack of an efficient market for the securities may make them difficult to value.

|
Tax-Managed Investment Risk. A portion of the Fund’s portfolio will be managed using a tax-managed approach. Market conditions may limit the Fund’s ability to implement its tax-managed approach. For example, market conditions may limit the Fund’s ability to generate tax losses or to generate qualified dividend income, which is generally taxed to noncorporate shareholders at favorable rates. The tax-managed strategy may affect the investment decisions made for the Fund. For example, the Fund’s tax-managed strategy may cause the Fund to hold a security in order to achieve more favorable tax-treatment or to sell a security in order to create tax losses. The Fund’s ability to utilize various tax-management techniques may be curtailed or eliminated in the future by legislation or regulation. Although the Fund expects that a smaller portion of its total return will consist of taxable distributions to shareholders as compared to non-tax managed funds, there can be no assurance about the size of taxable distributions to shareholders. The performance of the Fund may deviate from that of non-tax managed funds and may not provide as high a return before or after consideration of federal income tax consequences as non-tax managed funds. The Fund’s tax-sensitive investment strategy involves active management, which may cause the Fund to realize capital gains.

Interest Rate Risk. Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short term or long term interest rates rise sharply or otherwise change in a manner not anticipated by a Sub-Adviser. Securities with longer maturities tend to be more sensitive to changes in interest rates, causing them to be more volatile than securities with shorter maturities. Securities with shorter maturities tend to provide lower returns and be less volatile than securities with longer maturities. Changing interest rates may have unpredictable effects on the markets and the Fund’s investments and may also affect the liquidity of fixed income securities and instruments held by the Fund. Declines in interest rate levels could cause the Fund’s earnings to fall below the Fund’s expense ratio, resulting in a negative yield and a decline in the Fund’s share price.

Convertible Securities Risk. Securities that can be converted into common stock, such as certain securities and preferred stock, are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to the risks associated with equity securities.

Equity Securities Risk. The Fund is designed for investors who can accept the risks of investing in a portfolio with significant holdings of equity securities. Equity securities tend to be more volatile than other investment choices, such as debt and money market instruments. The value of your investment may decrease in response to overall stock market movements or the value of individual securities held by the Fund.

Growth Stock Risk. Growth stocks are typically priced higher than other stocks, in relation to earnings and other measures, because investors believe they have more growth potential. This potential may or may not be realized and, if it is not realized, may result in a loss to the Fund. Growth stock prices also tend to be more volatile than the overall market. Because different types of stocks go out of favor with investors depending on market and economic conditions, the Fund’s return may be adversely affected during a market downturn and when growth stocks are out of favor.

Illiquid Securities Risk. Investing in illiquid securities is subject to certain risks, such as limitations on resale and uncertainty in determining valuation. Limitations on resale may adversely affect the marketability of portfolio securities and the Fund might be unable to dispose of restricted or other illiquid securities promptly or at reasonable prices and might thereby experience difficulty satisfying redemptions within seven days. The Fund might, in order to dispose of restricted securities, have to register securities resulting in additional expense and delay. Adverse market conditions could impede such a public offering of such securities. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

Special Situations Risk. The Fund will seek to benefit from “special situations,” such as mergers, reorganizations, or other unusual events expected to affect a particular issuer. There is a risk that the “special situation” might not occur or involve longer time frames than originally expected, which could have a negative impact on the price of the issuer’s securities and fail to produce gains or produce a loss for the Fund.

Sub-Adviser and Strategy Concentration Risk. Because the Adviser will not be subject to fixed limitations upon the amount of Fund assets that may be invested with a single Sub-Adviser or in a single investment strategy, the Fund may be more heavily exposed to the investment judgments of one or more Sub-Advisers or the possible increased risk of investing in a limited number of investment strategies.

●
|
Tax-Managed Investment Risk. A portion of the Fund’s portfolio will be managed using a tax-managed approach. Market conditions may limit the Fund’s ability to implement its tax-managed approach. For example, market conditions may limit the Fund’s ability to generate tax losses or to generate qualified dividend income, which is generally taxed to noncorporate shareholders at favorable rates. The Fund’s ability to utilize various tax-management techniques may be curtailed or eliminated in the future by legislation or regulation. Although the Fund expects that a smaller portion of its total return will consist of taxable distributions to shareholders as compared to non-tax managed funds, there can be no assurance about the size of taxable distributions to shareholders. The performance of the Fund may deviate from that of non-tax managed funds and may not provide as high of a return before or after consideration of federal income tax consequences as non-tax managed funds.

|
American Depositary Receipts and Global Depository Receipts Risk. ADRs and GDRs may be subject to some of the same risks as direct investment in foreign companies, which includes international trade, currency, political, regulatory and diplomatic risks. In a sponsored ADR arrangement, the foreign issuer assumes the obligation to pay some or all of the depositary’s transaction fees. Under an unsponsored ADR arrangement, the foreign issuer assumes no obligations and the depositary’s transaction fees are paid directly by the ADR holders. Because unsponsored ADR arrangements are organized independently and without the cooperation of the issuer of the underlying securities, available information concerning the foreign issuer may not be as current as for sponsored ADRs and voting rights with respect to the deposited securities are not passed through. GDRs can involve currency risk since, unlike ADRs, they may not be U.S. dollar-denominated.

Currency and Exchange Risk. Investments in currencies, currency futures contracts, forward currency exchange contracts or similar instruments, as well as securities that are denominated in foreign currency, are subject to the risk that the value of a particular currency will change in relation to one or more other currencies. Currency rates in foreign countries may fluctuate significantly over short periods of time for any number of reasons, including changes in interest rates, rates of inflation, governmental surpluses or deficits, intervention (or the failure to intervene) by U.S. or foreign governments, actions of central banks or supranational entities and the imposition of currency controls or other political developments in the U.S. or abroad. In addition, the Fund may engage in currency hedging transactions. Currency hedging transactions are subject to the risk that a result opposite expectations occurs (an expected decline turns into a rise and conversely) resulting in a loss to the Fund.

Emerging Markets Risk. The Fund will invest in emerging markets, which may carry more risk than investing in developed foreign markets. Risks associated with investing in emerging markets include limited information about companies in these countries, greater political and economic uncertainties compared to developed foreign markets, underdeveloped securities markets and legal systems, potentially high inflation rates, and the influence of foreign governments over the private sector. Further, investments in certain emerging markets are subject to an elevated risk of loss resulting from market manipulation and the imposition of exchange controls (including repatriation
|
restrictions). The legal rights and remedies available for investors in emerging markets may be more limited than the rights and remedies available in the U.S., and the ability of U.S. authorities (e.g., SEC and the U.S. Department of Justice) to bring actions against bad actors in emerging markets may be limited.

|
ETF Risk. ETFs are a type of investment company bought and sold on a securities exchange. An ETF often represents a fixed portfolio of securities designed to track a particular market index. In such cases, the risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their net asset value (“NAV”).

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

In addition, shareholders will be exposed to the investment risks associated with investments in the other investment companies. Investments by the Fund in other investment companies, including ETFs , will be subject to the limitations of the Investment Company Act of 1940 (the “1940 Act”). Pursuant to Rule 12d1-4 , the Fund may invest in other investment companies beyond the limits contained in the 1940 Act, subject to certain conditions imposed by Rule 12d1-4 including limits on control and voting of acquired funds’ shares, evaluations and findings by investment advisers, fund investment agreements and limits on most three-tier fund structures.

Mid-Capitalization Risk. Securities of mid-capitalization companies are often more volatile and less liquid than investments in larger companies. The frequency and volume of trading in securities of mid-capitalization companies may be substantially less than is typical of larger companies. As a result, the securities of mid-capitalization companies may be subject to greater and more abrupt price fluctuations. In addition, mid-capitalization companies may lack the management experience, financial resources and product diversification of larger companies, making them more susceptible to market pressures and business failure.

Prepayment Risk.

Issuers may decrease prepayments of principal when interest rates increase, extending the maturity of a fixed income security and causing the value of the security to decline.

|
Small and Micro-Capitalization Risk. The securities of small and micro-cap companies may be more volatile in price, have wider spreads between their bid and ask prices, and have significantly lower trading volumes than the securities of larger capitalization companies. As a result, the purchase or sale of more than a limited number of shares of the securities of a smaller company may affect its market price. The Fund may need a considerable amount of time to purchase or sell its positions in these securities. Some small and micro-cap companies are followed by few, if any, securities analysts, and there tends to be less publicly available information about such companies. The small and micro-cap securities in which the Fund invests may be traded only in the over-the-
|
counter market or on a regional securities exchange, may be listed only in the quotation service commonly known as the “pink sheets,” and may not be traded every day or in the volume typical of trading on a national securities exchange. They generally have even more limited trading volumes and are subject to even more abrupt or erratic market price movements than are mid and large cap securities, and the Fund may be able to deal with only a few market-makers when purchasing and selling securities. Small and micro-cap companies also may have limited markets, financial resources or product lines, may lack management depth, and may be more vulnerable to adverse business or market developments. Smaller company stocks may fall out of favor relative to mid or large cap stocks, which may cause the Fund to underperform other equity funds that focus on mid or large cap stocks. Moreover, the lack of an efficient market for the securities may make them difficult to value.

The use of artificial intelligence and machine learning could exacerbate these risks.The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

IPO Risk. IPO risk is the risk that the market value of IPO shares will fluctuate considerably due to certain factors, such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about the issuer. The purchase of IPO shares may involve high transaction costs. IPO shares are subject to market risk and liquidity risk. When the Fund’s asset base is small, a significant portion of the Fund’s performance could be attributable to investments in IPOs, because such investments would have a magnified impact on the Fund. As the Fund’s assets grow, the effect of the Fund’s investments in IPOs on the Fund’s performance probably will decline, which could reduce the Fund’s performance. Because of the price volatility of IPO shares, the Fund may choose to hold IPO shares for a very short period of time. This may increase the turnover of the Fund’s portfolio and may lead to increased expenses to the Fund, such as commissions and transaction costs. In addition, the Adviser cannot guarantee continued access to IPOs.

The purchase of IPO shares may involve high transaction costs. IPO shares are subject to market risk and liquidity risk. When the Fund’s asset base is small, a significant portion of the Fund’s performance could be attributable to investments in IPOs, because such investments would have a magnified impact on the Fund. As the Fund’s assets grow, the effect of the Fund’s investments in IPOs on the Fund’s performance probably will decline, which could reduce the Fund’s performance. Because of the price volatility of IPO shares, the Fund may choose to hold IPO shares for a very short period of time. This may increase the turnover of the Fund’s portfolio and may lead to increased expenses to the Fund, such as commissions and transaction costs. In addition, the Adviser cannot guarantee continued access to IPOs.

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

Foreign Securities Risk. International investing may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and other financial practices. The Fund may invest in securities of foreign issuers either directly or through depositary receipts. Depositary receipts may be available through “sponsored” or “unsponsored” facilities. Holders of unsponsored depositary receipts generally bear all of the costs of the unsponsored facility. The depository of an unsponsored facility is frequently under no obligation to distribute shareholder communications received from the issuer of the deposited security or to pass through, to the holders of the receipts, voting rights with respect to the deposited securities. The depository of unsponsored depositary receipts may provide less information to receipt holders. Participatory notes (“P-notes”) are derivative instruments used by investors to take positions in certain foreign securities. P-notes present

Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its NAV. Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

Illiquid Investments Risk. Investing in illiquid investments is subject to certain risks, such as limitations on resale and uncertainty in determining valuation. Limitations on resale may adversely affect the marketability of portfolio securities and the Fund might be unable to dispose of restricted or other illiquid investments promptly or at reasonable prices and might thereby experience difficulty satisfying redemptions within seven days. The Fund might, in order to dispose of restricted securities, have to register securities resulting in additional expense and delay. Adverse market conditions could impede such a public offering of such securities. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

Exchange-Traded Fund Risk. Exchange-traded funds (“ETFs”) are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their net asset value (“NAV”).

REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. The value of securities issued by REITs is affected by tax and regulatory requirements and by perceptions of management skill. They also may be affected by general economic conditions and are subject to heavy cash flow dependency, defaults by borrowers or tenants, self-liquidation at an economically disadvantageous time, and the possibility of failing to qualify for favorable tax treatment under applicable U.S. or foreign law and/or to maintain exempt status under the 1940 Act. Additional risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. REITs that invest in real estate mortgages are also subject to prepayment risk. Investing in REITs may involve risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume, engage in dilutive offerings and may be subject to more abrupt or erratic price movements than larger company securities. Historically, small capitalization stocks, such as REITs, have been more volatile in price than the larger capitalization stocks included in the S&P 500® Index. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the 1940 Act.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments. The use of derivatives is also subject to operational and legal risks. Operational risks generally refer to risks related to potential operational issues, including documentation issues, settlement issues, system failures, inadequate controls, and human error. Legal risks generally refer to risks of loss resulting from insufficient documentation, insufficient capacity or authority of counterparty, or legality or enforceability of a contract.

Emerging Markets Risk. Investment in emerging market securities involves greater risk than that associated with investment in securities of issuers in developed foreign countries. These risks include volatile currency exchange rates, periods of high inflation, increased risk of default, greater social, economic and political uncertainty and instability, less governmental supervision and regulation of securities markets, weaker auditing and financial reporting standards, lack of liquidity in the markets, and the significantly smaller market capitalizations of emerging market issuers. The information available of an emerging market issuer may be less reliable than for comparable issuers in more

developed capital markets. In addition, investments in certain emerging markets are subject to an elevated risk of loss resulting from market manipulation and the imposition of exchange controls (including repatriation restrictions). The legal rights and remedies available for investors in emerging markets may be more limited than the rights and remedies available in the U.S., and the ability of U.S. authorities (e.g., SEC and the U.S. Department of Justice) to bring actions against bad actors in emerging markets may be limited.

Sustainable Investment Risk. The sustainability criterion required for Fund investment may cause the Fund to not invest in certain industries or issuers. As a result, the Fund may be overweight or underweight in certain industries or issuers relative to its benchmark index, which may cause the Fund’s performance to be more or less sensitive to developments affecting those industries or issuers. Sustainability information provided by issuers, upon which the portfolio managers may rely, continues to develop, and may be incomplete, inaccurate, use different methodologies, or be applied differently across companies and industries. Further, the regulatory landscape for sustainable investing in the United States is still developing and future rules and regulations may require the Fund to modify or alter its investment process. Similarly, government policies incentivizing issuers to engage in sustainable practices may fall out of favor, which could potentially limit the Fund’s investment universe. There is also a risk that the companies identified through the investment process may fail to adhere to sustainable business practices, which may result in the Fund selling a security when it might otherwise be disadvantageous to do so. There is no guarantee that sustainable investments will outperform the broader market on either an absolute or relative basis.

|
Illiquid Investments Risk. Investing in illiquid investments is subject to certain risks, such as limitations on resale and uncertainty in determining valuation. Limitations on resale may adversely affect the marketability of portfolio securities and the Fund might be unable to dispose of restricted or other illiquid investments promptly or at reasonable prices and might thereby experience difficulty satisfying redemptions within seven days. The Fund might, in order to dispose of restricted securities, have to register securities resulting in additional expense and delay. Adverse market conditions could impede such a public offering of such securities. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

Small-Cap Companies Risk. The small capitalization equity securities in which the Fund may invest may be traded only in the over-the-counter market or on a regional securities exchange, may be listed only in the quotation service commonly known as the “pink sheets,” and may not be traded every day or in the volume typical of trading on a national securities exchange. These securities may also be subject to wide fluctuations in market value. The trading market for any given small capitalization equity security may be sufficiently small as to make it difficult for the Fund to dispose of a substantial block of such securities. The sale by the Fund of portfolio securities to meet redemptions may require the Fund to sell its small capitalization securities at a discount from market prices or during periods when, in the Adviser’s judgment, such sale is not desirable. Moreover, the lack of an efficient market for these securities may make them difficult to value.

|
REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. The value of securities issued by REITs is affected by tax and regulatory requirements and by perceptions of management skill. They also may be affected by general economic conditions and are subject to heavy cash flow dependency, defaults by borrowers or tenants, self-liquidation at an economically disadvantageous time, and the possibility of failing to qualify for favorable tax treatment under applicable U.S. or foreign law and/or to maintain exempt status under the 1940 Act. Additional risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency,
|
defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. REITs that invest in real estate mortgages are also subject to prepayment risk. Investing in REITs may involve risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume, engage in dilutive offerings and may be subject to more abrupt or erratic price movements than larger company securities. Historically, small capitalization stocks, such as REITs, have been more volatile in price than the larger capitalization stocks included in the S&P 500® Index. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the 1940 Act.

High Yield Debt Obligations Risk. The Fund may invest up to 20% of its net assets in high yield debt obligations, such as bonds and debentures, issued by corporations and other business organizations. An issuer of debt obligations may default on its obligation to pay interest and repay principal. Also, changes in the financial strength of an issuer or changes in the credit rating of a security may affect its value. Such high yield debt obligations are referred to as “junk bonds” and are not considered to be investment grade.

An increase in the strength of the U.S. dollar relative to a foreign currency may cause the U.S. dollar value of an investment in that country to decline. Foreign currencies also are subject to risks caused by inflation, interest rates, budget deficits and low savings rates, political factors and government controls.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

Derivatives Risk. The Fund’s investments in derivative instruments, which include futures and options on securities, securities indices or currencies, options on these futures, forward foreign currency contracts and interest rate or currency swaps, may be leveraged and result in losses exceeding the amounts invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments. The use of derivatives is also subject to operational and legal risks. Operational risks generally refer to risks related to potential operational issues, including documentation issues, settlement issues, system failures, inadequate controls, and human error. Legal risks generally refer to risks of loss resulting from insufficient documentation, insufficient capacity or authority of counterparty, or legality or enforceability of a contract.

| |
●
|
Short Sales Risk. Short sales of securities may result in gains if a security’s price declines, but may result in losses if a security’s price rises. In a rising market, short positions may be more likely to result in losses because securities sold short may be more likely to increase in value. Short selling also involves the risks of: increased leverage, and its accompanying potential for losses; the potential inability to reacquire a security in a timely manner, or at an acceptable price; the possibility of the lender terminating the loan at any time, forcing the Fund to close the transaction under unfavorable circumstances; and the additional costs that may be incurred. Short sales “against the box” may protect the Fund against the risk of losses in the value of a portfolio security because any decline in value of the security should be wholly or partially offset by a corresponding gain in the short position. Any potential gains in the security, however, would be wholly or partially offset by a corresponding loss in the short position. Short sales that are not “against the box” involve a form of investment leverage, and the amount of the Fund’s loss on a short sale is potentially unlimited.

IPO Risk. IPO risk is the risk that the market value of IPO shares will fluctuate considerably due to certain factors, such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about the issuer. The purchase of IPO shares may involve high transaction costs. IPO shares are subject to market risk and liquidity risk. When the Fund’s asset base is small, a significant portion of the Fund’s performance could be attributable to
|
investments in IPOs, because such investments would have a magnified impact on the Fund. As the Fund’s assets grow, the effect of the Fund’s investments in IPOs on the Fund’s performance probably will decline, which could reduce the Fund’s performance. Because of the price volatility of IPO shares, the Fund may choose to hold IPO shares for a very short period of time. This may increase the turnover of the Fund’s portfolio and may lead to increased expenses to the Fund, such as commissions and transaction costs. In addition, the Adviser cannot guarantee continued access to IPOs.

In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

|
Exchange-Traded Fund Risk. Exchange-traded funds (“ETFs”) are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their net asset value (“NAV”).

Convertible Securities Risk. Securities that can be converted into common stock, such as certain securities and preferred stock, are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to the risks associated with equity securities.

IPO Risk. IPO risk is the risk that the market value of IPO shares will fluctuate considerably due to certain factors, such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about the issuer. The purchase of IPO shares may involve high
|
transaction costs. IPO shares are subject to market risk and liquidity risk. When the Fund’s asset base is small, a significant portion of the Fund’s performance could be attributable to investments in IPOs, because such investments would have a magnified impact on the Fund. As the Fund’s assets grow, the effect of the Fund’s investments in IPOs on the Fund’s performance probably will decline, which could reduce the Fund’s performance. Because of the price volatility of IPO shares, the Fund may choose to hold IPO shares for a very short period of time. This may increase the turnover of the Fund’s portfolio and may lead to increased expenses to the Fund, such as commissions and transaction costs. In addition, the Adviser cannot guarantee continued access to IPOs.

Portfolio Turnover Risk. The Fund may frequently trade its portfolio securities, resulting in higher brokerage commissions and transaction costs, which could lower the Fund’s performance. In addition to lower performance, high portfolio turnover could result in taxable capital gains. A portfolio turnover rate of 100% is considered to be high. The annual portfolio turnover rate for the Fund is not expected to exceed 400%; however, it may be higher if the Adviser believes it wil improve the Fund’s performance.

Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. The value of securities issued by REITs is affected by tax and regulatory requirements and by perceptions of management skill. They also may be affected by general economic conditions and are subject to heavy cash flow dependency, defaults by borrowers or tenants, self-liquidation at an economically disadvantageous time, and the possibility of failing to qualify for favorable tax treatment under applicable U.S. or foreign law and/or to maintain exempt status under the 1940 Act. Additional risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. REITs that invest in real estate mortgages are also subject to prepayment risk. Investing in REITs may involve risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume, engage in dilutive offerings and may be subject to more abrupt or erratic price movements than larger company securities. Historically, small capitalization stocks, such as REITs, have been more volatile in price than the larger capitalization stocks included in the S&P 500® Index. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the Investment Company Act of 1940, as amended.

OTC Risk. Securities traded on OTC markets are not listed and traded on an organized exchange such as the New York Stock Exchange (“NYSE”). Generally, the volume of trading in an unlisted or OTC common stock is less than the volume of trading in an exchange-listed stock. As a result, the market liquidity of some stocks in which the Fund invests may not be as great as that of exchange-listed stocks and, if the Fund were to dispose of such stocks, the Fund may have to offer the shares at a discount from recent prices or sell the shares in small lots over an extended period of time. In addition, penny stocks and pink sheet stocks can be classified as OTC stocks.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

|
| Risk [Text Block] |
| |
●
|
Counterparty Risk: The derivative contracts entered into by the Fund or its Subsidiary may be privately negotiated in the over-the-counter market. These contracts also involve exposure to credit risk, since contract performance depends in part on the financial condition of the counterparty. The participants in the over-the-counter market are typically not subject to credit evaluations and regulatory oversight as are members of “exchange based” markets. Relying on a counterparty exposes the Fund to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not
|
bona fide) or because of a credit or liquidity problem, thus causing the Fund to suffer a loss. If a counterparty defaults on its payment obligations to the Fund, this default will cause the value of an investment in the Fund to decrease. In addition, to the extent the Fund deals with a limited number of counterparties, it will be more susceptible to the credit risks associated with those counterparties. The Fund is neither restricted from dealing with any particular counterparty nor from concentrating any or all of its transactions with one counterparty. The ability of the Fund to transact business with any one or number of counterparties and the absence of a regulated market to facilitate settlement may increase the potential for losses by the Fund.

Credit Risk: Credit risk refers to the possibility that the issuer of the security or a counterparty in respect of a derivative instrument will not be able to satisfy its payment obligations to the Fund when due. This may impair the Fund’s liquidity or cause a deterioration in the Fund’s net asset value (“NAV”). In addition, the Fund may incur expenses in an effort to protect the Fund’s interests or enforce its rights against an issuer, guarantor or counterparty or may be hindered or delayed in exercising these rights. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. Securities rated in the four highest categories by the rating agencies are considered investment grade, but they may also have some speculative characteristics. Investment grade ratings do not guarantee that securities will not lose value or default. In addition, the credit quality of securities may be lowered if an issuer’s financial condition changes.

Currency rates in foreign countries may fluctuate significantly over short periods of time for any number of reasons, including changes in interest rates, rates of inflation, governmental surpluses or deficits, intervention (or the failure to intervene) by U.S. or foreign governments, actions of central banks or supranational entities and the imposition of currency controls or other political developments in the U.S. or abroad.

The Fund and its Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders.

|
Derivatives Risk: Derivatives include instruments and contracts that are based on, and are valued in relation to, one or more underlying securities, financial benchmarks or indices, such as futures, options, swap agreements and forward contracts. Derivatives typically have economic leverage inherent in their terms. Such leverage will magnify any losses. See “Leverage/Volatility Risk” below. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments. The primary types of derivatives in which the Fund or its Subsidiary invest in are swap agreements, futures contracts and forward contracts. Futures contracts, forward contracts and swap agreements can be highly volatile, illiquid and difficult to value, and changes in the value of such instruments held directly or indirectly by the Fund may not correlate with the underlying instrument or reference assets, or the Fund’s other investments. Although the value of futures contracts, forward contracts and swap agreements depends largely upon price movements in the underlying instrument or reference asset, there are additional risks associated with futures contracts, forward contracts and swap agreements that are possibly greater than the risks associated with investing directly in the underlying instruments or reference assets, including illiquidity risk, leveraging risk and counterparty credit risk. A small position in futures contracts, forward contracts or swap agreements could have a potentially large impact on the Fund’s performance. Trading restrictions or limitations may be imposed by an exchange, and government regulations may restrict trading in swap agreements, futures contracts and options and forward contracts. The use of derivatives is also subject to operational and legal risks. Operational risks generally refer to risks related to potential operational issues, including documentation issues,
|
settlement issues, system failures, inadequate controls, and human error. Legal risks generally refer to risks of loss resulting from insufficient documentation, insufficient capacity or authority of counterparty, or legality or enforceability of a contract.

Government Intervention and Regulatory Changes: The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) (which was passed into law in July 2010) significantly revised and expanded the rulemaking, supervisory and enforcement authority of federal bank, securities and commodities regulators. There can be no assurance that future regulatory actions including, but not limited to, those authorized by the Dodd-Frank Act will not adversely impact the Fund. Major changes resulting from legislative or regulatory actions could materially affect the profitability of the Fund or the value of investments made by the Fund or force the Fund to revise its investment strategy or divest certain of its investments. Any of these developments could expose the Fund to additional costs, taxes, liabilities, enforcement actions and reputational risk.
|
| |
|
Rule 18f-4 under the 1940 Act provides for the regulation of a registered investment company’s use of derivatives and certain related investments. Rule 18f-4 imposes limits on the amount of derivatives a fund can enter into, treats derivatives as senior securities so that a failure to comply with the limits would result in a statutory violation, and requires the Fund to establish and maintain a comprehensive derivatives risk management program and appoint a derivatives risk manager. The Fund is required to comply with Rule 18f-4 and has adopted procedures for investing in derivatives and other transactions in compliance with Rule 18f-4.

|
Interest Rate Risk: Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short term or long term interest rates rise sharply or otherwise change in a manner not anticipated by the Adviser. Securities with longer maturities tend to be more sensitive to changes in interest rates, causing them to be more volatile than securities with shorter maturities. Securities with shorter maturities tend to provide lower returns and be less volatile than securities with longer maturities. Changing interest rates may have unpredictable effects on the markets and the Fund’s investments and may also affect the liquidity of fixed income securities and instruments held by the Fund. Declines in interest rate levels could cause the Fund’s earnings to fall below the Fund’s expense ratio, resulting in a negative yield and a decline in the Fund’s share price. In addition, certain countries and regulatory bodies may use negative interest rates as a monetary policy tool to encourage economic growth during periods of deflation. In a negative interest rate environment, debt instruments may trade at negative yields, which means the purchaser of the instrument may receive at maturity less than the total amount invested.

The derivatives and other investments held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held directly by the Fund. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws or acts of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to continue to operate as it does currently and could adversely affect the Fund.

●
|
Tax Risk: In order to qualify as a regulated investment company (“RIC”), the Fund must meet certain requirements regarding the source of its income, the diversification of its assets and the distribution of its income. Under the test regarding the source of a RIC’s income, at least 90% of the gross income of the RIC each year must be qualifying income, which consists of dividends, interest, gains on investment assets and other categories of investment income. Treasury Regulations provide that income from a foreign subsidiary that is a controlled foreign corporation is qualifying income for purposes of the Fund remaining qualified as a RIC for U.S. federal income tax purposes. Notwithstanding the treatment of controlled foreign corporations in the regulations, the Internal Revenue Services (“IRS”) may take the position that income earned by the Fund through the Cayman Subsidiary may not be qualifying income because of its investment in commodities. Additionally, the IRS may take the position that certain commodity-linked structured notes may not be qualifying income. A recharacterization of income from the Cayman Subsidiary or commodity-linked structured notes could cause the Fund to fail to qualify as a RIC. If the Fund were to fail to qualify as a RIC and became subject to federal income tax, shareholders of the Fund would be subject to diminished returns. Changes in the laws or acts of the United States and/or the Cayman Islands could result in the inability of the Fund and/or its Subsidiary to operate as described in this Prospectus and the Statement of Additional Information (“SAI”) and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax or withholding tax on the Subsidiary. If Cayman Islands acts change such that the Subsidiary must pay Cayman Islands taxes, Fund shareholders would likely suffer decreased investment returns.

Equity Securities Risk: The Fund may invest in, or have exposure to, equity securities. Equity securities tend to be more volatile than other investment choices, such as debt and money market instruments. The value of your investment may decrease in response to overall stock market movements or the value of individual securities.

Portfolio Turnover Risk: The Fund may frequently buy and sell portfolio securities and other assets to rebalance the Fund’s exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than you expect.

| Risk [Text Block] |

●
|
Emerging Market Risk: The Fund intends to have exposure to emerging markets due to the Fund’s investments in certain stock index futures and foreign exchange instruments. Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets may be considered speculative. Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging financial markets have far lower trading volumes and less liquidity than developed markets; are subject to greater social, economic and political instability; have less governmental supervision and regulation of securities markets; and have weaker auditing and financial reporting standards. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets. Further, investments in certain emerging markets are subject to an elevated risk of loss resulting from market manipulation and the imposition of exchange controls (including repatriation restrictions). The legal rights and remedies available for investors in emerging markets may be more limited than the rights and remedies available in the U.S., and the ability of U.S. authorities (e.g., SEC and the U.S. Department of Justice) to bring actions against bad actors in emerging markets may be limited.

Commodities Risk: Exposure to the commodities markets (including financial futures markets) may subject the Fund through its investment in the Subsidiary to greater volatility than investments in traditional securities. Prices of commodities and related contracts may fluctuate significantly over short periods for a variety of reasons, including changes in interest rates or factors affecting a particular industry or commodity, such as weather, disease (including pandemics), tariffs, embargoes or other trade barriers, acts of war or terrorism, or political and regulatory developments.

|
Fixed-Income Risk: Fixed income securities, such as U.S. Treasuries, or derivatives based on fixed income securities, are subject to credit risk and interest rate risk. Credit risk, as described more fully herein, refers to the possibility that the issuer of a debt security will be unable to make interest payments or repay principal when it becomes due. Interest rate risk refers to fluctuations in the value of a debt security resulting from changes in the general level of interest rates. Prices of fixed income securities tend to move inversely with changes in interest rates. Typically, a rise in rates will adversely affect fixed income security prices and, accordingly, the Fund’s returns and share price. In addition, the Fund may be subject to “call” risk, which is the risk that during a period of falling interest rates the issuer may redeem a security by repaying it early (which may reduce the Fund’s income if the proceeds are reinvested at lower interest rates), and “extension” risk, which occurs during a rising interest rate environment because certain obligations will be paid off by an issuer more slowly than anticipated (causing the value of those securities held by the Fund to fall).

|
Foreign Market Risk: As a general rule, there is less legal and regulatory protection for investors in foreign markets than that available domestically. Additionally, trading on foreign exchanges is subject to the risks presented by exchange controls, expropriation, increased tax burdens and exposure to local economic declines and political instability. Some foreign derivative markets are so-called principals’ markets in which performance is the responsibility only of the individual counterparty with whom the trader has entered into a commodity interest transaction and not of the exchange or clearing corporation. International trading activities are subject to foreign exchange risk. Certain foreign securities in which the Fund may invest may be traded in markets that close before the time that the Fund calculates its NAV. Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

|
| Risk [Text Block] |
| |
●
|
Futures and Forward Contracts and Related Risks: The successful use of forward and futures contracts draws upon the Adviser’s skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of futures and forward contracts are:
|
| |
●
|
Futures and forward contracts have a high degree of price variability and are subject to occasional rapid and substantial changes;
|
| |
●
|
the imperfect correlation between the change in market value of the forward or futures contracts and the market value of the underlying instrument or reference assets with respect to such contracts;
|
| |
●
|
possible lack of a liquid secondary market for a forward or futures contract and the resulting inability to close a forward or futures contract when desired;
|
| |
●
|
possible market disruption or other extraordinary events, including but not limited to, governmental intervention;
|
| |
●
|
potentially unlimited losses caused by unanticipated market movements;
|
| |
●
|
the Fund’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors;
|
| |
●
|
the possibility that the counterparty will default in the performance of its obligations; and
|
| |
●
|
if the Fund has insufficient cash, it may either have to sell securities from its portfolio to meet daily variation margin requirements with respect to its derivative instruments or close certain positions at a time when it may be disadvantageous to do so.
|
| |
|
The use of futures contracts, forward contracts and derivative instruments will have the economic effect of financial leverage. Financial leverage magnifies exposure to the swings in prices of an asset class underlying an investment and results in increased volatility, which means the Fund will have the potential for greater losses than if the Fund did not employ leverage in its investment activity. Leveraging tends to magnify, sometimes significantly, the effect of any increase or decrease in the Fund’s exposure to an asset class and may cause the value of the Fund’s securities or related derivatives instruments to be volatile. Accordingly, the Fund’s NAV may be volatile because of its investment exposure to the Fund.
|
| |
|
There is no assurance that the Fund’s investment in a derivative instrument with leveraged exposure to certain investments and markets will enable the Fund to achieve its investment objective.

|

|
| Risk [Text Block] |
| |
●
|
Government Agency Risk: Direct obligations of the U.S. Government such as U.S. Treasury bills, notes and bonds are supported by its full faith and credit. Indirect obligations issued by Federal agencies and government-sponsored entities generally are not backed by the full faith and credit of the U.S. Treasury. Accordingly, while U.S. Government agencies and instrumentalities may be chartered or sponsored by Acts of Congress, their securities are neither issued nor guaranteed by the U.S. Treasury. Some of these indirect obligations may be supported by the right of the issuer to borrow from the Treasury; others are supported by the discretionary authority of the U.S. Government to purchase the agency’s obligations; still others are supported only by the credit of the instrumentality. The maximum potential liability of the issuers of some U.S. Government securities may greatly exceed their current resources, including any legal right to support from the U.S. Treasury. It is possible that the issuers of such securities will not have the funds to meet their payment obligations in the future.

| Campbell Systematic Macro Fund | Leverage/Volatility Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
| |
●
|
Leverage/Volatility Risk: Although the Fund will not borrow funds for trading, the Fund should be considered highly leveraged and is suitable only for investors with high tolerance for investment risk. Leverage embedded in the various derivative instruments traded may result in the Fund or its Subsidiary holding positions whose face or notional value may be many times the Fund’s NAV. For example, the amount of margin funds necessary to be deposited in order to enter into a futures, forward or option contract position is typically from 2% to 10% of the total face or notional value of the contract. As a result of this leveraging, even a small movement in the price of a commodity can cause a correspondingly large profit or loss. Losses incurred on leveraged investments increase in direct proportion to the degree of leverage employed. Furthermore, derivative instruments and futures contracts are highly volatile and are subject to occasional rapid and substantial fluctuations. Consequently, you could lose all or substantially all of your investment in the Fund should the Fund’s trading positions suddenly turn unprofitable.
|
| |
|
The Fund’s NAV is expected over short-term periods to be volatile because of the significant use of direct and indirect investments that have a leveraging effect. Volatility is a statistical measurement of the magnitude of up and down asset price fluctuations over time. Rapid and dramatic price swings will result in high volatility. The Fund’s returns are expected to be volatile; however, the actual or realized volatility level for longer or shorter periods may be materially higher or lower depending on market conditions and investors may suffer a significant and possibly a complete loss on their investment in the Fund.

●
|
governmental, agricultural, trade, fiscal, monetary and exchange control programs and policies;

Non-Diversification Risk: The Fund is a non-diversified investment company, which means that more of the Fund’s assets may be invested in the securities of a single issuer than could be invested in the securities of a single issuer by a diversified investment company.

Currency Risk. Currency risk results from changes in the rate of exchange between the currency of the country in which a foreign company is domiciled or keeps its books and the U.S. dollar. Whenever the Fund holds securities valued in a foreign currency or holds the currency itself in connection with its purchases and sales of foreign securities, changes in the exchange rate add to or subtract from the value of the investment in U.S. dollars. The Fund generally does not seek to hedge currency risk, and although the Sub-Adviser considers currency risks as part of its investment process, its judgments in this regard may not always be correct.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Adviser, the Sub-Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund, the Adviser, and the Sub-Adviser have
|
limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund, the Adviser or the Sub-Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

Investing in securities of foreign companies involves risks generally not associated with investments in the securities of U.S. companies, including the risks associated with fluctuations in foreign currency exchange rates, less stringent investor protections, unreliable and untimely information about issuers, and political and economic instability. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its NAV. Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV.

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: “Authorized Participants, Market Makers and Liquidity Providers Concentration Risk,” “Cash Transactions Risk,” “Secondary Market Trading Risk,” and “Shares May Trade at Prices Other Than Net Asset Value (“NAV”) Risk.”
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to its net asset value (“NAV”) and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Shares.
|
| |
●
|
Cash Transactions Risk. Unlike certain ETFs, the Fund may effect its creations and redemptions partially or wholly for cash rather than on an in-kind basis. Because of this, the Fund may incur costs such as brokerage costs or be unable to realize certain tax benefits associated with in-kind transfers of portfolio securities that may be realized by other ETFs. These costs may decrease the Fund’s NAV to the extent that the costs are not offset by a transaction fee payable by an AP. Shareholders may be subject to tax on gains they would not otherwise have been subject to and/or at an earlier date than if the Fund had effected redemptions wholly on an in-kind basis.
|
| |
●
|
Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, The Nasdaq Stock Market LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. Trading may be halted because of market conditions or for reasons that, in the view of the Exchange, make trading in the Fund inadvisable. These may include: (a) the extent to which trading is not occurring in the securities and/or the financial instruments composing the Fund’s Portfolio; or (b) whether other unusual conditions or circumstances detrimental to the maintenance of a fair and orderly market are present. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. There is a risk that market prices for Fund Shares will vary significantly from the Fund’s NAV. Where all or portion of the Fund’s underlying securities trade in a foreign market that is closed when the market in which the Fund’s Shares are listed is open for trading, there may be changes between the last quote of the underlying securities’ value in the closed foreign market and the value of such underlying securities during the Fund’s domestic trading day.

Liquidity Risk. Liquidity risk is the risk, due to certain investments trading in lower volumes or to market and economic conditions that the Fund may be unable to find a buyer for its investments when it seeks to sell them or to receive the price it expects based on the Fund’s valuation of the investments. Events that may lead to increased redemptions, such as market disruptions, may also negatively impact the liquidity of the Fund’s investments when it needs to dispose of them. If the Fund is forced to sell its investments at an unfavorable time and/or under adverse conditions in order to meet redemption requests, such sales could negatively affect the Fund. Liquidity issues may also make it difficult to value the Fund’s investments.

Depositary Receipts Risk. The Fund may purchase depositary receipts (American Depositary Receipts (“ADRs”), European Depositary receipts (“EDRs”), Global Depositary receipts (“GDRs”), and Non-Voting Depositary Receipts (“NVDRs”)) to facilitate its investments in foreign securities. By investing in ADRs rather than investing directly in the securities of foreign issuers, the Fund can avoid currency risks during the settlement period for purchase and sales. However, ADRs do not eliminate all the risks inherent in investing in the securities of foreign issuers. Depositary receipts may be issued in a sponsored program, in which an issuer has made arrangements to have its securities traded in the form of depositary receipts, or in an unsponsored program, in which the issuer may not be directly involved. The holders of depositary receipts that are unsponsored generally bear various costs associated with the facilities, while a larger portion of the costs associated with sponsored depositary receipts are typically borne by the foreign issuers.

Markets may experience temporary closures, extreme volatility, severe losses, reduced liquidity, and increased trading costs. Such events may adversely affect the Fund and its investments and may impact the Fund’s ability to purchase or sell securities or cause elevated tracking error and increased premiums or discounts to the Fund’s NAV.

Micro-Cap and Small Cap Companies Risk. Investments in securities of micro- and small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of larger-capitalization companies. The securities of micro- and small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. Some micro- and small-capitalization companies have limited product lines, markets, and financial and managerial resources and tend to concentrate on fewer geographical markets relative to larger capitalization companies. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies. Micro- and small-capitalization companies also may be particularly sensitive to changes in interest rates, government regulation, borrowing costs and earnings.

Private Placements Risk. Investments in private placements could decrease the Fund’s liquidity profile or prevent the Fund from disposing of such securities promptly at advantageous prices. Private placements may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available, and the Fund might be unable to dispose of such securities promptly or at prices reflecting their true value. Transaction costs may be higher for these securities, and the Fund may only get limited information about the issuer of a private placement security, so it may be less able to anticipate a loss.

Securities Issued By Other Investment Companies Risk The Fund may invest in shares of other investment companies, including other mutual funds, money market funds, ETFs, HOLDRs, unit investment trusts, and closed-end funds, to gain exposure to a particular portion of the market rather than purchase securities directly. Investing in another investment company exposes the Fund to all the risks of that investment company, and, in general, subjects it to a pro rata portion of the other investment company’s fees and expenses.

Warrants and rights are not dividend-paying investments and do not have the voting rights of common stock. They also do not represent any rights in the assets of the issuer. As a result, warrants and rights may be considered more speculative than direct equity investments.

Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and Matson Money have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

ETFs are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their NAV.

●
|
Inflation protected securities, such as TIPS, generally will fluctuate in response to changes in real interest rates, generally decreasing when real interest rates rise and increasing when real interest rates fall. In addition, interest payments on inflation-protected securities will generally vary up or down along with the rate of inflation. Real interest rates are generally measured as a nominal interest less an inflation rate. As such, investors should be aware that an investment in TIPS over a particular timeframe may decrease in value even in an inflationary environment. There can be no assurance that the inflation index used will accurately measure the real rate of inflation in the prices of goods and services. Because of their inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds.

ETFs are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. the Portfolio may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Portfolio’s own expenses. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their NAV.

Inflation protected securities, such as TIPS, generally will fluctuate in response to changes in real interest rates, generally decreasing when real interest rates rise and increasing when real interest rates fall. In addition, interest payments on inflation-protected securities will generally vary up or down along with the rate of inflation. Real interest rates are generally measured as a nominal interest less an inflation rate. As such, investors should be aware that an investment in TIPS over a particular timeframe may decrease in value even in an inflationary environment. There can be no assurance that the inflation index used will accurately measure the real rate of inflation in the prices of goods and services. Because of their inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Fool 100 Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fool 100 Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Fool 100 Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks or result in cyber security incidents that implicate personal data. The Fool 100 Fund and the Adviser have limited ability to prevent or mitigate cybersecurity incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fool 100 Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fool 100 Fund or its service providers may adversely impact and cause financial losses to the Fool 100 Fund or its shareholders. Issuers of securities in which the Fool 100 Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyberfailures.

ETF Risk. The Fool 100 Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fool 100 Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fool 100 Fund Shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Fool 100 Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fool 100 Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
|
| |
●
|
Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, the Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fool 100 Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.

Equity Markets Risk. The equity securities held in the Fool 100 Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fool 100 Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stocks and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

Index Rankings and Methodology Risk. The Fool 100 Index is comprised of the 100 largest U.S. companies that are either active recommendations of TMF’s newsletter or are among the 150 highest rated U.S. companies in TMF’s analyst opinion database, and are weighted based on their market value relative to the total market value of other companies in the Fool 100 Index. Factors used by TMF’s analysts in their qualitative and quantitative analysis of companies included in the Fool 100 Index, and the weight placed on those factors, may not be predictive of a security’s value and, thus, have an adverse effect on the Fool 100 Fund. In addition, changes in TMF’s recommendations or rankings methodologies may have an adverse effect on the Fool 100 Fund. Factors that affect a security’s value can change over time, and these changes may not be reflected in the Fool 100 Index methodology. Moreover, the methodology and the calculation of the Fool 100 Index could be subject to errors. If the composition of the Fool 100 Index reflects such errors, the Fool 100 Fund’s portfolio can be expected to reflect the errors, too.

Passive Investment Risk. The Fool 100 Fund is not actively managed and the Adviser does not attempt to take defensive positions in any market conditions, including adverse markets. The Fool 100 Fund and its Adviser will not sell shares of an equity security due to current or projected underperformance of a security, industry, or sector, unless that security is removed from the Fool 100 Index or the selling of shares of that security is otherwise required upon a reconstitution of the Fool 100 Index as addressed in the Index methodology.

Currency Risk. Currency risk results from changes in the rate of exchange between the currency of the country in which a foreign company is domiciled or keeps its books and the U.S. dollar. Whenever the Global Opportunities Fund holds securities valued in a foreign currency or holds the currency itself in connection with its purchases and sales of foreign securities, changes in the exchange rate add to or subtract from the value of the investment in U.S. dollars. The Global Opportunities Fund generally does not seek to hedge currency risk, and although the Adviser considers currency risks as part of its investment process, its judgments in this regard may not always be correct.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Global Opportunities Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Global Opportunities Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Global Opportunities Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks or result in cyber security incidents that implicate personal data. The Global Opportunities Fund and the Adviser have limited ability to prevent or mitigate cybersecurity incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Global Opportunities Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Global Opportunities Fund or its service providers may adversely impact and cause financial losses to the Global Opportunities Fund or its shareholders. Issuers of securities in which the Global Opportunities Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyberfailures.

Foreign Investments Risk. The Global Opportunities Fund invests in the securities of foreign companies. Investing in securities of foreign companies involves risks generally not associated with investments in the securities of U.S. companies, including the risks associated with fluctuations in foreign currency exchange rates, less stringent investor protections, unreliable and untimely information about issuers, and political and economic instability. Foreign securities in which the Global Opportunities Fund invests may be traded in markets that close before the time that the Global Opportunities Fund calculates its net asset value (“NAV”). Furthermore, certain foreign securities in which the Global Opportunities Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Global Opportunities Fund does not calculate its NAV. As a result, the value of the Global Opportunities Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Global Opportunities Fund’s shares.

|
ETF Risk. The Global Opportunities Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: “Authorized Participants, Market Makers and Liquidity Providers Concentration Risk,” “Secondary Market Trading Risk,” and “Shares May Trade at Prices Other Than NAV Risk.”
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“APs”) may engage in creation or redemption transactions directly with the Fund. The Global Opportunities Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Global Opportunities Fund Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Global Opportunities Fund Shares trading at a premium or discount to NAV. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
|
| |
●
|
Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, the Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Global Opportunities Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.

Depositary Receipts Risk. The Global Opportunities Fund may purchase depositary receipts (American Depositary Receipts (“ADRs”), European Depositary receipts (“EDRs”), Global Depositary receipts (“GDRs”), and Non-Voting Depositary Receipts (“NVDRs”)) to facilitate its investments in foreign securities. By investing in ADRs rather than investing directly in the securities of foreign issuers, the Global Opportunities Fund can avoid currency risks during the settlement period for purchase and sales. However, ADRs do not eliminate all the risks inherent in investing in the securities of foreign issuers. Depositary receipts may be issued in a sponsored program, in which an issuer has made arrangements to have its securities traded in the form of depositary receipts, or in an unsponsored program, in which the issuer may not be directly involved. The holders of depositary receipts that are unsponsored generally bear various costs associated with the facilities, while a larger portion of the costs associated with sponsored depositary receipts are typically borne by the foreign issuers.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of the overall domestic and global economy, interest rates, competition, and consumer confidence. Success depends heavily on disposable household income and consumer spending. Also, companies in the consumer discretionary sector may be subject to severe competition, which may have an adverse impact on their respective profitability.

A variety of factors including economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets may adversely affect securities markets generally, which could adversely affect the value of the Global Opportunities Fund’s investments in common stocks.

Quality growth investing focuses on companies that appear attractively priced in light of factors such as the quality of management, sustainability of competitive advantage, or growth potential of cash flow. If the Adviser’s assessment of a company’s quality or intrinsic value or its prospects for exceeding earnings expectations or market conditions is inaccurate, the Global Opportunities Fund could suffer losses or produce poor performance relative to other funds. In addition, the stocks of quality companies can continue to be undervalued by the market for long periods of time. As a consequence of our investing style we expect the Global Opportunities Fund will underperform the market and its peers over short timeframes.

In many less developed markets, there is less governmental supervision and regulation of business and industry practices, stock exchanges, brokers, and listed companies than there is in more developed markets. The securities markets of certain countries in which the Global Opportunities Fund may invest may also be smaller, less liquid, and subject to greater price volatility than those of more developed markets. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets. The Global Opportunities Fund seeks to invest no more than 50% of its net assets in emerging market countries.

Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Small-Cap Growth Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.

Small Cap Companies Risk. Investments in securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of larger-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. Some small capitalization companies have limited product lines, markets, and financial and managerial resources and tend to concentrate on fewer geographical markets relative to larger capitalization companies. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies. Small-capitalization companies also may be particularly sensitive to changes in interest rates, government regulation, borrowing costs and earnings.

This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Small-Cap Growth Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stocks and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

Investment Style Risk. The Small-Cap Growth Fund pursues a quality growth style of investing. Quality growth style investing focuses on companies that appear attractive in light of factors such as the quality of management, sustainability of competitive advantage, or growth potential of cash flow. If the Adviser’s assessment of a company’s quality or intrinsic value or its prospects for exceeding earnings expectations or market conditions is inaccurate, the Small-Cap Growth Fund could suffer losses or produce poor performance relative to other funds. In addition, the stocks of quality companies can continue to be undervalued by the market for long periods of time. As a consequence of its investing style the Small-Cap Growth Fund may underperform the market and its peers over short timeframes.

ETF Risk. The Next Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: “Authorized Participants, Market Makers and Liquidity Providers Concentration Risk,” “Secondary Market Trading Risk,” and “Shares May Trade at Prices Other Than NAV Risk.”
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Next Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Next Fund Shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation
|
and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Next Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Next Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
| |
●
|
Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, the Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.

decrease during periods of rising interest rates. The magnitude of these fluctuations will generally be greater if the Fund holds securities with longer maturities or lower quality ratings. The interest earned on the Fund’s investments in fixed income securities may decline when prevailing interest rates fall. The Fund may lose money if short term or long term interest rates rise sharply or otherwise change in a manner not anticipated by the Adviser. The Fund is also subject to the risk that the income generated by its investments may not keep pace with inflation. Interest rates in the United States and many other countries have risen in recent periods and may continue to remain elevated for the foreseeable future. Because longer-term inflationary pressure may result from the U.S. government’s fiscal policies, the Fund may experience higher interest rates over its investment horizon. Additionally, as a result of increasing interest rates, reserves held by banks and other financial institutions in bonds and other debt securities could face a significant decline in value relative to deposits and liabilities, which coupled with general economic headwinds resulting from a changing interest rate environment, creates liquidity pressures at such institutions. As a result, certain sectors of the credit markets could experience significant declines in liquidity, and it is possible that the Fund will not be able to manage this risk effectively.

| Risk [Text Block] |
Concentration Risk - Mortgage-Backed Securities. To the extent the Fund’s investments are concentrated in the securities of a particular market segment or asset class, the Fund’s investments may be more susceptible to an increased risk of loss due to adverse events, than the market as a whole. As of August 31, 2025, the Fund had 13.9% of the value of its net assets invested in collateralized mortgage-backed securities. Mortgage-backed securities are less effective than other types of securities as a means of “locking in” attractive long-term interest rates because of the need to reinvest prepayments of principal and the possibility of significant unscheduled prepayments resulting from declines in interest rates. Mortgage-backed securities are subject to greater prepayment risk during periods when interest rates decline. Prepayment risk is the risk that the principal on mortgage-backed securities, other asset-backed securities or any fixed income security with an embedded call option may be prepaid at any time, which could reduce yield and market value. This could reduce the effective maturity of a mortgage-backed security and cause the Fund to reinvest its assets at a lower prevailing interest rate. Mortgage-backed securities are subject to extension risk which is the risk that rising interest rates will increase the effective maturity of mortgage-backed securities due to the deceleration of prepayments. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain mortgage-backed securities. Non-agency mortgage-backed securities have no direct or indirect government or agency guarantees of payment and may have a limited market especially when there is perceived weakness in the mortgage and real estate market sectors. Mortgage-backed securities may also be subject to risks unique to the housing industry, including mortgage lending practices, defaults, foreclosures and changes in real estate values. The Fund’s investments in collateralized mortgage obligations are subject to the risk that payments may not be made on time, prepayment and extension risk and market risk when interest rates rise. Collateralized mortgage securities may be less liquid and may exhibit greater price volatility than other types of mortgage securities. The value of mortgage-backed securities may be negatively affected by higher interest rates and deteriorating economic conditions and could potentially result in a higher rate of defaults and foreclosures. As a result of the Fund’s policy to concentrate in mortgage-backed securities, the Fund will be subject to the risks associated with these securities to a greater degree than a fund that does not concentrate in mortgage-backed securities.

Corporate Bonds. As of August 31, 2025, the Fund had 26.7% of the value of its net assets invested in corporate bonds. Corporate bonds are typically issued by public or private companies to finance their operations and are distinct from debt securities issued by a government or its agencies. Corporate bonds may be either secured or unsecured. Corporate bonds may have more speculative characteristics in their ability to repay principal and interest than other types of fixed income securities, such as government securities. Corporate bonds contain elements of both interest-rate risk and credit risk and are subject to the risks associated with other debt securities, among other risks. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates and may also be affected by the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the marketplace. There is a risk that the issuers of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by an instrument.

|
| Risk [Text Block] |
Investment and Market Risk. The Fund is subject to market risk, which is the risk that the Fund’s share price will fluctuate as market prices fluctuate. At times there may be an imbalance of supply and demand in the fixed income markets which could result in greater price volatility, less liquidity, wider trading spreads and a lack of price transparency. Decisions by the Federal Reserve on interest rate policy and the potential market reaction to these initiatives can have a significant effect on the value of fixed-income securities. The Fund is also subject to management risk, which is the risk that the Adviser’s analysis of economic conditions and expectations regarding interest rate changes may fail to produce the intended results. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund may not be appropriate for use as a complete investment program. Events such as war, military conflict, acts of terrorism, social unrest, natural disasters, recessions, inflation, rapid interest rate changes, supply chain disruptions, sanctions, the spread of infectious illness or other public health threats could also significantly impact the Fund and its investments.

Other Fixed Income Securities Risks:
| |
■
|
Credit Risk. Credit risk is the risk that the issuer of a security will not be able to make payments of interest and principal when due. Deterioration in the financial condition of an issuer or deterioration in general economic conditions could cause an issuer to fail to make timely payments of principal and interest. The value of any underlying collateral, the creditworthiness of the borrower and the priority of the lien are each of great importance. The Adviser cannot guarantee the adequacy of the protection of the Fund’s interests, including the validity or enforceability of the loan and the maintenance of the anticipated priority and perfection of the applicable security interests. Furthermore, the Adviser cannot assure that claims may not be asserted that might interfere with enforcement of the rights of the holder(s) of the relevant debt. Additionally, changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may affect the value of the Fund’s investments in that issuer. A credit agency’s rating represents the organization’s opinion as to the credit quality of a security but is not an absolute standard of quality or guarantee as to the creditworthiness of an issuer. Ratings from a credit agency present an inherent conflict of interest, because the agency is paid by the entities whose securities they rate. Rating agencies may fail to move quickly enough to change ratings in response to changing circumstances, and a rating may not reflect the fine shadings of risks within a given quality grade.

■
|
LIBOR Risk. Most London Interbank Offered Rates (“LIBORs”) were generally phased out by the end of 2021, and some regulated entities have ceased to enter into new LIBOR-based contracts beginning January 1, 2022. As of September 30, 2024, the UK FCA has confirmed that all publications of LIBOR, including all synthetic publications of the 1-, 3-, and 6-month U.S. dollar LIBOR settings, have ceased. Neither the effect of the LIBOR transition process nor its ultimate success can yet be known. Although the transition away from LIBOR has become increasingly well-defined, any potential effects of the transition away from LIBOR and other benchmark rates on financial markets, a fund or the financial instruments in which a fund invests can be difficult to ascertain. Not all existing LIBOR-based instruments may have alternative rate-setting provisions and there remains uncertainty regarding the willingness and ability of issuers to add alternative rate-setting provisions in certain existing instruments. Global regulators have advised market participants to cease entering into new contracts using LIBOR as a reference rate, and it is possible that investments in LIBOR-based instruments could invite regulatory scrutiny. Instruments in which the Fund invests historically paid interest at floating rates based on LIBOR or were subject to interest caps or floors
|
| |
|
based on LIBOR. The Fund and issuers of instruments in which the Fund invests also historically obtained financing at floating rates based on LIBOR. In addition, a liquid market for newly-issued instruments that use a reference rate other than LIBOR still may be developing.
|
| |
■
|
Liquidity Risk. Liquidity risk is the risk that a limited market for a security may make it difficult for that security to be sold at an advantageous time or price, which could prevent the Fund from selling the security at the approximate price that it is valued or the time it desires to sell. Liquidity risk may be magnified during times of instability in the credit markets, rising interest rates, high selling activity, or other circumstances where investor redemptions from fixed income mutual funds may be higher than normal. The capacity of traditional dealers to engage in fixed income trading has not kept pace with the fixed income market’s growth, causing dealer inventories to be at or near historical lows relative to market size. The reduction in dealer inventories could lead to decreased liquidity, increased volatility and wider spreads, which may become exacerbated during periods of economic or political stress. Lower rated securities may be subject to greater levels of liquidity risk. If a fixed income security is downgraded or declines in price, the market demand may be limited, making that security difficult to sell. Additionally, the market for certain fixed-income securities may become illiquid under adverse market or economic conditions, independent of any specific adverse changes in the conditions of a particular issuer.
|
| |
■
|
Maturity Risk. Longer-term securities generally have greater price fluctuations and are more sensitive to interest rate changes than shorter-term securities. Therefore, the Fund may experience greater price fluctuations when it holds securities with longer maturities.
|
| |
■
|
Prepayment and Extension Risk. The Fund’s performance could be affected if borrowers pay back principal on certain debt securities before or after the market anticipates such payments, shortening or lengthening their duration. Due to a decline in interest rates or an excess in cash flow, a debt security might be called or otherwise converted, prepaid or redeemed before maturity. As a result, the Fund may have to reinvest the proceeds in an investment offering a lower yield, may not benefit from any increase in value that might otherwise result from declining interest rates and may lose any premium it paid to acquire the security. Floating rate securities can be less sensitive to prepayment risk. Higher interest rates generally result in slower payoffs, which effectively increase duration, heighten interest rate risk, and increase the potential for price declines.
|
| |
■
|
Privately Placed and Rule 144A Securities. As of August 31, 2024, the Fund had 14.0% of the value of its net assets invested in Rule 144A securities. Investments in Rule 144A securities and other privately placed securities may be less liquid and subject to greater volatility than publicly traded securities. An insufficient number of qualified institutional buyers purchasing Rule 144A securities could adversely affect the marketability of such securities and the Fund may be unable to dispose of such securities promptly or at a reasonable price. Although these securities may be resold in privately negotiated transactions, the prices realized from these sales could be less than those originally paid by the Fund or less than what may be considered the fair value of such securities. Companies whose securities are not publicly traded may not be subject to the disclosure and other investor protection requirements that might be applicable to publicly traded securities. Additionally, privately held companies typically have limited operating histories, narrower, less established product lines and smaller market shares than larger businesses, which tend to render them more vulnerable to competitors’ actions, market conditions and consumer sentiment in respect of their products or services, as well as general economic downturns. Such companies may experience operating losses, which may be substantial, and there can be no assurance when or if such companies will operate at a profit. At the time of a fund’s investment, there is generally little publicly available information about these companies since they are primarily privately owned and there can be no assurance that the information that a fund does obtain with respect to any such investment is reliable.

■
|
SOFR Risk. The Secured Overnight Financing Rate Data (“SOFR”) is intended to be a broad measure of the cost of borrowing funds overnight in transactions that are collateralized by U.S. Treasury securities. SOFR is calculated based on transaction-level repo data collected from various sources. For each trading day, SOFR is calculated as a volume-weighted median rate derived from such data. SOFR is calculated and published by the Federal Reserve Bank of New York (“FRBNY”). If data from a given source required by the FRBNY to calculate SOFR is unavailable for any day, then the most recently available data for that segment will be used, with certain adjustments. If errors are discovered in the transaction data or the calculations underlying SOFR after its initial publication on a given day,
|
| |
|
SOFR may be republished at a later time that day. Rate revisions will be effected only on the day of initial publication and will be republished only if the change in the rate exceeds one basis point. Because SOFR is a financing rate based on overnight secured funding transactions, it differs fundamentally from LIBOR. LIBOR was intended to be an unsecured rate that represents interbank funding costs for different short-term maturities or tenors. It was a forward-looking rate reflecting expectations regarding interest rates for the applicable tenor. Thus, LIBOR was intended to be sensitive, in certain respects, to bank credit risk and to term interest rate risk. In contrast, SOFR is a secured overnight rate reflecting the credit of U.S. Treasury securities as collateral. Thus, it is largely insensitive to credit-risk considerations and to short-term interest rate risks. SOFR is a transaction-based rate, and it has been more volatile than other benchmark or market rates, such as three-month LIBOR, during certain periods. For these reasons, among others, there is no assurance that SOFR, or rates derived from SOFR, will perform in the same or similar way as LIBOR would have performed at any time, and there is no assurance that SOFR-based rates will be a suitable substitute for LIBOR. SOFR has a limited history, having been first published in April 2018. The future performance of SOFR, including following the discontinuation of LIBOR and SOFR-based reference rates, cannot be predicted based on SOFR’s history or otherwise. Levels of SOFR in the future may bear little or no relation to historical levels of SOFR, LIBOR or other rates.

|

|
| Risk [Text Block] |
Risks Associated With Particular Types of Fixed-Income Securities:
| |
■
|
Convertible Securities. Convertible securities are bonds, preferred stocks, and other securities that pay interest or dividends and are convertible into common stocks or carry the right to purchase common stock. In general, a convertible security performs more like a stock when the price of the underlying stock is high (because it is assumed that it will be converted into the stock) and more like a bond when the price of the underlying stock is low (because it is assumed that it will mature without being converted). Therefore a convertible security is subject to risks associated with both fixed-income and equity securities. The return and value of an equity security will fluctuate in response to stock market movements. Factors such as earnings, interest rates, political events, war, acts of terrorism, government defaults or shutdowns, public health issues, recessions or other events could have a significant effect on the stock market and the value of convertible securities.
|
| |
■
|
High Yield Securities. High-yield securities or junk bonds are often considered to be speculative and involve greater risk of default or price changes than investment grade fixed-income securities due to changes in the issuer’s or the market’s perception of an issuer’s creditworthiness. Therefore, the Fund’s investments in high-yield securities expose it to a substantial degree of credit risk. The issuers of these securities may not be as financially strong as the issuers of higher rated securities. Prices of lower-rated securities have been found to be less sensitive to interest rate changes and more sensitive to adverse economic changes and individual corporate developments than more highly rated investments. When a security’s rating is reduced below investment grade, it may be more difficult for the Fund to receive income from its investment.
|
| |
■
|
Other Asset-Backed Securities. Asset-backed securities may be affected by factors concerning the interests in and structure of the issuer or the originator of the receivables, the creditworthiness of the entities that provide any supporting letters of credit or other credit enhancements or the market’s assessment of the quality of the underlying security.
|
| |
■
|
U.S. Government Securities. Some U.S. Government securities, such as U.S. Government agency notes and bonds, are neither insured nor guaranteed by the U.S. Government, meaning they are only supported by the right of the issuer to borrow from the U.S. Government or by the credit of the agency issuing the obligation. If the Fund invests in a U.S. Government security that is not backed by the U.S. Government, there is no assurance that the U.S. Government would provide support, and the Fund’s performance could be adversely impacted if there is a deterioration in the financial condition of the issuer. Further, from time to time, uncertainty regarding the status of negotiations in the U.S. government to increase the statutory debt ceiling could impact the creditworthiness of the U.S. and could impact the liquidity of the U.S. Government Securities markets and ultimately the Fund.

Sector Concentration. At times when the Fund emphasizes a particular sector of the fixed income market, the value of the Fund’s net assets will be more susceptible to the financial, market or economic events affecting that sector than would be the case for mutual funds that do not emphasize investment in a particular sector. This may increase the risk of loss associated with an investment in the Fund and increase the volatility of the Fund’s share price.

Credit Risk. Credit risk is the risk that an issuer or other obligated party of a debt security may be unable or unwilling to make interest and principal payments when due. Deterioration in the financial condition of an issuer or deterioration in general economic conditions could cause an issuer to fail to make timely payments of principal and interest. The value of any underlying collateral, the creditworthiness of the borrower and the priority of the lien are each of great importance. The Adviser cannot guarantee the adequacy of the protection of the Fund’s interests, including the validity or enforceability of the loan and the maintenance of the anticipated priority and perfection of the applicable security interests. Furthermore, the Adviser cannot assure that claims may not be asserted that might interfere with enforcement of the rights of the holder(s) of the relevant debt. Additionally, changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. Securities rated in the four highest categories by the rating agencies are considered investment grade but they may also have some speculative characteristics. Investment grade ratings do not guarantee that bonds will not lose value or default. In addition, the credit quality of securities may be lowered if an issuer’s financial condition changes. The Fund could also be delayed or hindered in its enforcement of rights against an issuer, guarantor, or counterparty.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, Adviser, Sub-Adviser, custodian, transfer agent, distributor and/or other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and its Adviser and Sub-Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

Derivatives Risk. The Fund’s investments in derivative instruments including options, swaps and futures, which may be leveraged, may result in losses. Investments in derivative instruments may result in losses exceeding the amounts invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.
The use of derivatives is also subject to operational and legal risks. Operational risks generally refer to risks related to potential operational issues, including documentation issues, settlement issues, system failures, inadequate controls, and human error. Legal risks generally refer to risks of loss resulting from insufficient documentation, insufficient capacity or authority of counterparty, or legality or enforceability of a contract.
Rule 18f-4 under the 1940 Act provides for the regulation of a registered investment company’s use of derivatives and certain related investments. Rule 18f-4 imposes limits on the amount of derivatives a fund can enter into, treats derivatives as senior securities so that a failure to comply with the limits would result in a statutory violation, and requires the Fund to establish and maintain a comprehensive derivatives risk management program and appoint a derivatives risk manager. The Fund is required to comply with Rule 18f-4 and has adopted procedures for investing in derivatives and other transactions in compliance with Rule 18f-4.

Emerging Markets Risk. Investment in emerging market securities involves greater risk than that associated with investment in foreign securities of developed foreign countries. These risks include volatile currency exchange rates, periods of high inflation, increased risk of default, greater social, economic and political uncertainty and instability, less governmental supervision and regulation of securities markets, weaker auditing and financial reporting standards, lack of liquidity in the markets, and the significantly smaller market capitalizations of emerging market issuers. In addition, the information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets. Investments in certain emerging markets are subject to an elevated risk of loss resulting from market manipulation and the imposition of exchange controls (including repatriation restrictions). The legal rights and remedies available for investors in emerging markets may be more limited than the rights and remedies available in the U.S., and the ability of U.S. authorities (e.g., SEC and the U.S. Department of Justice) to bring actions against bad actors in emerging markets may be limited.

Fixed Income Securities Risk. Fixed income securities in which the Fund or an Underlying Fund may invest are subject to certain risks, including: interest rate risk, prepayment risk and credit/default risk. Interest rate risk involves the risk that prices of fixed income securities will rise and fall in response to interest rate changes. Prepayment risk involves the risk that in declining interest rate environments prepayments of principal could increase and require the Fund or an Underlying Fund to reinvest proceeds of the prepayments at lower interest rates. Credit risk involves the risk that the credit rating of a security may be lowered.

Interest Rate Risk. Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short term or long term interest rates rise sharply or otherwise change in a manner not anticipated by the Sub-Adviser. Changing interest rates may have unpredictable effects on the markets and the Fund’s investments and may also affect the liquidity of fixed income securities and instruments held by the Fund. Declines in interest rate levels could cause the Fund’s earnings to fall below the Fund’s expense ratio, resulting in a negative yield, and a decline in the Fund’s share price. A general rise in interest rates may cause investors to move out of fixed income securities on a large scale, which could adversely affect the price and liquidity of fixed income securities and could also result in increased redemptions for the Fund. Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund. Interest rates in the United States and many other countries have risen in recent periods and may continue to remain elevated for the foreseeable future. Because longer-term inflationary pressure may result from the U.S. Government’s fiscal policies, the Fund may experience higher interest rates over its investment horizon. Additionally, as a result of increasing interest rates, reserves held by banks and other financial institutions in bonds and other debt securities could face a significant decline in value relative to deposits and liabilities, which coupled with general economic headwinds resulting from a changing interest rate environment, creates liquidity pressures at such institutions. As a result, certain sectors of the credit markets could experience significant declines in liquidity, and it is possible that the Fund will not be able to manage this risk effectively.

Leveraging Risk. Investments in derivative instruments may give rise to a form of leverage. The Sub-Adviser may engage in speculative transactions which involve substantial risk and leverage. The use of leverage by the Sub-Adviser may increase the volatility of the Fund. These leveraged instruments may result in losses to the Fund or may adversely affect the Fund’s NAV or total return, because instruments that contain leverage are more sensitive to changes in interest rates. The Fund may also have to sell assets at inopportune times to satisfy its obligations in connection with such transactions.

Market Risk. The value of the Fund’s holdings and investment return will fluctuate based upon changes in the value of its investments. The market value of the Fund’s holdings is based upon the market’s perception of value and is not necessarily an objective measure of an investment’s value. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. U.S. and international markets have experienced significant periods of volatility in recent years and months due to a number of economic, political and global macro factors, including the impact of the coronavirus (COVID-19) global pandemic, which has resulted in a public health crisis, business interruptions, growth concerns in the U.S. and overseas, rising unemployment claims, changed travel and social behaviors and reduced consumer spending. Uncertainties regarding interest rates, political events, rising government debt in the U.S. and trade tensions have also contributed to market volatility.

Government Intervention and Regulatory Changes Risk. The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) (which was passed into law in July 2010) significantly revised and expanded the rulemaking, supervisory and enforcement authority of federal bank, securities and commodities regulators. There can be no assurance that future regulatory actions including, but not limited to, those authorized by the Dodd-Frank Act will not adversely impact the Fund. Major changes resulting from legislative or regulatory actions could materially affect the profitability of the Fund or the value of investments made by the Fund or force the Fund to revise its investment strategy or divest certain of its investments. Any of these developments could expose the Fund to additional costs, taxes, liabilities, enforcement actions and reputational risk.

Portfolio Turnover Risk. The Fund will not consider portfolio turnover rate a limiting factor in making investment decisions consistent with the Fund’s investment objective and policies. Therefore, it is possible that the Fund may experience high rates of portfolio turnover. High portfolio turnover will cause the Fund to incur higher brokerage commissions and transaction costs, which could lower the Fund’s performance. In addition to lower performance, high portfolio turnover could result in taxable capital gains. A portfolio turnover rate of 100% is considered to be high.

The seller agrees to make specific payments to the buyer if a negative credit event occurs, such as the bankruptcy of or default by the issuer of the underlying debt instrument. The use of CDS involves investment techniques and risks different from those associated with ordinary portfolio security transactions, such as potentially heightened counterparty or concentration risks.

| Risk [Text Block] |
Futures Risk. The value of a futures contract tends to increase and decrease in correlation with the value of the underlying instrument. Risks of futures contracts may arise from an imperfect correlation between movements in the price of the futures and the price of the underlying instrument. The Fund’s use of futures contracts exposes the Fund to leverage risk because of the small margin requirements relative to the value of the futures contract. While futures contracts are generally liquid instruments, under certain market conditions they may become illiquid. The price of futures can be highly volatile; using them could lower total return, and the potential loss from futures could exceed the Fund’s initial investment in such contracts.

High Yield Securities Risk. High yield securities, which are rated below investment grade and commonly referred to as “junk” bonds, are high risk, speculative investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid and have more volatile prices than investment grade securities. Therefore, the Fund’s investments in high-yield securities expose it to a substantial degree of credit risk.

|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
Underlying Funds Risk. The Fund may invest in shares of registered, closed-end or open-end investment companies and ETFs. Investments in ETFs are subject to the risks of the securities in which those investment companies invest. Your cost of investing in the Fund, as a fund that invests in Underlying Funds, may be higher than the cost of investing in a fund that only invests directly in individual securities. Fund shareholders will indirectly pay a portion of the operating costs of the Underlying Funds in addition to the expenses of the Fund’s own operation. These costs include management, brokerage, shareholder servicing and other operational expenses. Unlike shares of typical mutual funds or unit investment trusts, shares of ETFs are designed to be traded throughout the trading day, bought and sold based on market prices rather than NAV. An investment in an ETF generally presents the following risks: (i) the same primary risks as an investment in a conventional mutual fund (i.e., one that is not exchange-traded) that has the same investment objectives, strategies and policies; (ii) the risk that an ETF may fail to accurately track the market segment or index that underlies its investment objective; (iii) price fluctuation, resulting in a loss to the Fund; (iv) the risk that an ETF may trade at a discount to its NAV; (v) the risk that an active market for an ETF’s shares may not develop or be maintained; and (vi) the risk that an ETF may no longer meet the listing requirements of any applicable exchanges on which that ETF is listed. The SEC has adopted revisions to the rules permitting funds to invest in other investment companies. These regulatory changes may adversely impact the Fund’s investment strategies and operations.

Preferred Securities Risk. Preferred securities are contractual obligations that entail rights to distributions declared by the issuer, but the issuer may be permitted to defer or suspend distributions for a certain period of time. Preferred securities may pay fixed or adjustable rates of return. Preferred securities generally are subordinated to bonds and other debt instruments in a company’s capital structure and therefore will be subject to greater credit risk than those debt instruments. Furthermore, a company’s preferred securities generally pay dividends only after the company makes required payments to holders of its bonds and other debt. In addition, preferred securities are subject to other risks, such as having no or limited voting rights, being subject to special redemption rights, having distributions deferred or skipped, having floating interest rates or dividends, which may result in a decline in value in a falling interest rate environment, having limited liquidity, changing or unfavorable tax treatments and possibly being issued by companies in heavily regulated industries.

Quantitative Trading Strategy Risk. The Sub-Adviser uses quantitative methods to select Fund investments. Securities or other investments selected using quantitative methods may perform differently from the market as a whole or from their expected performance for many reasons, including factors used in building the quantitative analytical framework, the weights placed on each factor, and changing sources of market returns, among others. Any errors or imperfections in quantitative analyses or models, or in the data on which they are based, could adversely affect the ability of the Sub-Adviser to use such analyses or models effectively, which in turn could adversely affect the Fund’s performance. There can be no assurance that these methodologies will help the Fund to achieve its investment objective.

U.S. Government Securities Risk. U.S. Government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity. Accordingly, the current market values for these securities will fluctuate with changes in interest rates. Although U.S. Treasury obligations are backed by the full faith and credit of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by U.S. Government agencies and U.S. Government-sponsored instrumentalities or enterprises are supported by varying degrees of credit and may or may not be backed by the full faith and credit of the U.S. Government. No assurance can be given that the U.S. Government will provide financial support
to its agencies and instrumentalities if it is not obligated by law to do so. Further, from time to time, uncertainty regarding the status of negotiations in the U.S. Government to increase the statutory debt ceiling could impact the creditworthiness of the U.S. and could impact the liquidity of the U.S. Government Securities markets and ultimately the Fund.

| Optima Strategic Credit Fund | Valuation Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
Valuation Risk. The debt securities in which the Fund and Underlying Funds invest typically are valued by a pricing service utilizing a range of market-based inputs and assumptions, including readily available market quotations obtained from broker-dealers making markets in such instruments, cash flows and transactions for comparable instruments. There is no assurance that the Fund or Underlying Funds will be able to sell a portfolio security at the price established by the pricing service, which could result in a loss to the Fund. Pricing services generally price debt securities assuming orderly transactions of an institutional “round lot” size, but some trades may occur in smaller, “odd lot” sizes, often at lower prices than institutional round lot trades. Different pricing services may incorporate different assumptions and inputs into their valuation methodologies, potentially resulting in different values for the same securities. As a result, if the Fund or an Underlying Fund were to change pricing services, or if the Fund or an Underlying Fund’s pricing service were to change its valuation methodology, there could be a material impact, either positive or negative, on the Fund’s NAV.

This may make the value of the Shares more susceptible to certain risks than shares of a diversified investment company. As a non-diversified fund, the Fund has a greater potential to realize losses upon the occurrence of adverse events affecting a particular issuer.

The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

The Adviser may be subject to potential conflicts of interest in selecting the Underlying Funds because the fees paid to the Adviser by some affiliated Underlying Funds may be higher than other Underlying Funds or the Underlying Funds may be in need of assets to enhance their appeal to other investors, liquidity and trading and/or to enable them to carry out their investment strategies. However, the Adviser is a fiduciary to the Fund and is legally obligated to act in the Fund’s best interest when selecting Underlying Funds.

Investment Companies and Exchange-Traded Funds (“ETFs”) Risk. The Fund’s investment performance may be affected by the investment performance of the Underlying Funds in which the Fund may invest. Investing in other investment companies, including affiliated and unaffiliated ETFs, may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. The risk of owning an investment company or ETF generally reflects the risks of owning the underlying investments the investment company an ETF holds. The Fund may incur brokerage fees in connection with its purchase of ETF shares. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their net asset value (“NAV”).

Small Cap Risk. The Fund will invest in Small Cap Stocks that may be more volatile than investments in issuers with larger market capitalizations. Issuers of Small Cap Stocks are not as diversified in their business activities as issuers with larger market capitalizations and are more susceptible to changes in the business cycle. Small companies may also have limited product lines, markets or financial resources and may be dependent on relatively small or inexperienced management groups. Additionally, the trading volume of small company securities may make them more difficult to sell than those of larger companies. Moreover, the lack of an efficient market for the securities may make them difficult to value.

Emerging Markets Risk: Investment in emerging market securities involves greater risk than that associated with investment in foreign securities of developed foreign countries. These risks include volatile currency exchange rates, periods of high inflation, increased risk of default, greater social, economic and political uncertainty and instability, less governmental supervision and regulation of securities markets, weaker auditing and financial reporting standards, lack of liquidity in the markets, and the significantly smaller market capitalizations of emerging market issuers. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets. In addition, investments in certain emerging markets are subject to an elevated risk of loss resulting from market manipulation and the imposition of exchange controls (including repatriation restrictions). The legal rights and remedies available for investors in emerging markets may be more limited than the rights and remedies available in the U.S., and the ability of U.S. authorities (e.g., SEC and the U.S. Department of Justice) to bring actions against bad actors in emerging markets may be limited.

■
|
Fixed Income Securities Risk. To the extent the Fund invests in Underlying Funds that invest in fixed income securities, the Fund will be subject to fixed income securities risks. While fixed income securities normally fluctuate less in price than stocks, there have been extended periods of increases in interest rates that have caused significant declines in fixed income securities prices. The values of fixed income securities may be affected by changes in the credit rating or financial condition of their issuers. Generally, the lower the credit rating of a security, the higher the degree of risk as to the payment of interest and return of principal.
|
Credit Risk. The issuer of a fixed income security may not be able to make interest and principal payments when due. Generally, the lower the credit rating of a security, the greater the risk that the issuer will default on its obligation. An Underlying Fund could also be delayed or hindered in its enforcement of rights against an issuer, guarantor, or counterparty.
Duration Risk. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities.
Income Risk. The Fund’s income could decline due to falling market interest rates. In a falling interest rate environment, the Fund may be required to invest in Underlying Funds that invest their assets in lower-yielding securities. Because interest rates vary, it is impossible to predict the income or yield of the Fund for any particular period.
Interest Rate Risk. The value of the Fund or an Underlying Fund may fluctuate based upon changes in interest rates and market conditions. As interest rates increase, the value of an Underlying Fund’s income-producing investments may go down. For example, bonds tend to decrease in value when interest rates rise. Debt obligations with longer maturities typically offer higher yields, but are subject to greater price movements as a result of interest rate changes than debt obligations with shorter maturities. Changing interest rates may have unpredictable effects on the markets and an Underlying Fund’s investments and may also affect the liquidity of fixed income securities and instruments held by an Underlying Fund.
Prepayment Risk. The Fund may invest in Underlying Funds that invest in securities that are subject to fluctuations in yield, due to prepayment rates that may be faster or slower than expected.
Rating Risk. If a rating agency gives a debt security a lower rating, the value of the debt security will decline because investors will demand a higher rate of return.

Foreign Custody Risk. An Underlying Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Underlying Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Underlying Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their NAV.

Junk bonds are considered predominately speculative with respect to the issuer’s continuing ability to make principal and interest payments. An economic downturn or period of rising interest rates could adversely affect the market for these securities and reduce an Underlying Fund’s ability to sell these securities (liquidity risk).

In a falling interest rate environment, the Fund may be required to invest in Underlying Funds that invest their assets in lower-yielding securities. Because interest rates vary, it is impossible to predict the income or yield of the Fund for any particular period.
Interest Rate Risk. The value of the Fund or an Underlying Fund may fluctuate based upon changes in interest rates and market conditions. As interest rates increase, the value of an Underlying Fund’s income-producing investments may go down. For example, bonds tend to decrease in value when interest rates rise. Debt obligations with longer maturities typically offer higher yields, but are subject to greater price movements as a result of interest rate changes than debt obligations with shorter maturities. Changing interest rates may have unpredictable effects on the markets and an Underlying Fund’s investments and may also affect the liquidity of fixed income securities and instruments held by an Underlying Fund.
Prepayment Risk. The Fund may invest in Underlying Funds that invest in securities that are subject to fluctuations in yield, due to prepayment rates that may be faster or slower than expected.
Rating Risk. If a rating agency gives a debt security a lower rating, the value of the debt security will decline because investors will demand a higher rate of return.

Foreign Custody Risk. An Underlying Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Underlying Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Underlying Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

Exchange-Traded Fund Risk. In addition to risks generally associated with investments in investment company securities, ETFs are subject to the following risks that do not apply to traditional mutual funds: (i) an ETF’s shares may trade at a market price that is above or below their net asset value (“NAV”); (ii) an active trading market for an ETF’s shares may not develop or be maintained; (iii) the ETF may employ an investment strategy that utilizes high leverage ratios; or (iv) trading of an ETF’s shares may be halted if the listing exchange’s officials deem such action appropriate, the shares are de-listed from the exchange, or the activation of market-wide “circuit breakers” (which are tied to large decreases in stock prices) halts stock trading generally. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their NAV.

High-Yield Securities (“Junk Bond”) Risk. To the extent that a Fund invests in Underlying Funds that invest in high-yield securities and unrated securities of similar credit quality (commonly known as “junk bonds”), the Fund may be subject to greater levels of interest rate and credit risk than funds that do not invest in such securities. Junk bonds are considered predominately speculative with respect to the issuer’s continuing ability to make principal and interest payments. An economic downturn or period of rising interest rates could adversely affect the market for these securities and reduce an Underlying Fund’s ability to sell these securities (liquidity risk). If the issuer of a security is in default with respect to interest or principal payments, the Underlying Fund may lose its entire investment, which will affect the Underlying Fund’s and the Fund’s return.

Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or

the Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data
breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares

|
ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: “Authorized Participants, Market Makers and Liquidity Providers Concentration Risk,” “Cash Transactions Risk,” “ Limitations of Intraday Indicative Value (IIV) Risk,” “Secondary Market Trading Risk,” and “Shares May Trade at Prices Other Than NAV Risk.”
|
| |
o
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as authorized participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares. Further, the Fund is utilizing a novel and unique structure, which may affect the number of entities willing to act as APs, market makers and/or liquidity providers.
|
| |
o
|
Cash Transactions Risk. Unlike traditional ETFs, the securities in the Fund’s basket of securities exchanged for a Creation Unit will not correspond pro rata to the positions in the Fund’s portfolio, and the Fund may effect its creations and redemptions partially or wholly for cash rather than on an in-kind basis. Because of this, the Fund may incur costs such as brokerage costs or be unable to realize certain tax benefits associated with in-kind transfers of portfolio securities that may be realized by other ETFs. These costs may decrease the Fund’s NAV to the extent that the costs are not offset by a transaction fee payable by an AP. Shareholders may be subject to tax on gains they would not otherwise have been subject to and/or at an earlier date than if the Fund had effected redemptions wholly on an in-kind basis.
|
| |
o
|
Limitations of Intraday Indicative Value (IIV) Risk. The Exchange or a market data vendor intends to disseminate the approximate per share value of the Fund’s Proxy Portfolio every 15 seconds (the ‘’intraday indicative value’’ or ‘’IIV’’). The IIV should not be viewed as a ‘’real-time’’ update of the NAV per share of the Fund because (i) the IIV is not be calculated in the same manner as the NAV, which is computed once a day, generally at the end of the business day, (ii) the calculation of NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV, (iii) unlike the calculation of NAV, the IIV does not take into account Fund expenses, and (iv) the IIV is based on the Proxy Portfolio and not on the Fund’s Actual Portfolio. The Fund, the Adviser and their affiliates are not involved in, or responsible for, any aspect of the calculation or dissemination of the Fund’s IIV, and the Fund, the Adviser and their affiliates do not make any warranty as to the accuracy of these calculations.
|
| |
o
|
Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, the NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. Trading may be halted because of market conditions or for reasons that, in the view of the Exchange, make trading in the Fund inadvisable. These may include: (a) the extent to which trading is not occurring in the securities and/or the financial instruments composing the Proxy Portfolio and/or Actual Portfolio; or (b) whether other unusual conditions or circumstances detrimental to the maintenance of a fair and orderly market are present. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
o
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although the Proxy Portfolio structure is intended to provide market participants with enough information to allow for an effective arbitrage mechanism that will help to keep the market price of the Fund’s Shares at or close to the Fund’s NAV, there is a risk that market prices for Fund Shares will vary significantly from the Fund’s NAV. This risk is heightened in times of market volatility or periods of steep market declines. This risk may be greater for the Fund than for traditional ETFs that disclose their full portfolio holdings on a daily basis because the publication of the Proxy Portfolio does not provide the same level of transparency as the daily publication of the actual portfolio by a traditional ETF. This could cause the Fund’s Shares to have wider bid/ask spreads and larger premiums/discounts than traditional ETFs using the same or similar investment strategies.

Generally, the volume of trading in an unlisted or OTC common stock is less than the volume of trading in an exchange-listed stock. As a result, the market liquidity of some stocks in which the Fund invests may not be as great as that of exchange-listed stocks and, if the Fund were to dispose of such stocks, the Fund may have to offer the shares at a discount from recent prices or sell the shares in small lots over an extended period of time.

| |
●
|
Semi-Transparent Structure Risk. The goal of the Proxy Portfolio is, during all market conditions, to track closely the daily performance of the Actual Portfolio and minimize intra-day misalignment between the performance of the Proxy Portfolio and the performance of the Actual Portfolio. The Proxy Portfolio is designed to reflect the economic exposures and the risk characteristics of the Actual Portfolio on any given trading day.
|
| |
●
|
The Proxy Portfolio methodology is novel and not yet proven as an effective arbitrage mechanism. The effectiveness of the Proxy Portfolio as an arbitrage mechanism is contingent upon, among other things, the Fund’s factor model analysis creating a Proxy Portfolio that performs in a manner substantially identical to the performance of the Fund’s Actual Portfolio. While the Proxy Portfolio may include some of the Fund’s holdings, it is not the Fund’s Actual Portfolio. ETFs trading on the basis of a published Proxy Portfolio may exhibit wider premiums and discounts, bid/ ask spreads, and tracking error than other ETFs using the same investment strategies that publish their portfolios on a daily basis, especially during periods of market disruption or volatility. Therefore, shares of the Fund may cost investors more to trade than shares of a traditional ETF.
|
| |
●
|
Each day the Fund calculates the overlap between the holdings of the prior business day’s Proxy Portfolio compared to the Actual Portfolio (i.e., proxy overlap) and the difference, in percentage terms, between the Proxy Portfolio per share NAV and that of the Actual Portfolio (i.e., tracking error). If the tracking error becomes large, there is a risk that the performance of the Proxy Portfolio may deviate from the performance of the Actual Portfolio.
|
| |
●
|
The Fund’s Board monitors its tracking error and bid/spread. If deviations become too large, the Board will consider the continuing viability of the Fund, whether shareholders are being harmed, and what, if any, corrective measures would be appropriate. See the Statement of Additional Information for further discussion of the Board’s monitoring responsibilities.
|
| |
●
|
Although the Fund seeks to benefit from keeping its portfolio information secret, market participants may attempt to use the Proxy Portfolio to identify a Fund’s trading strategy, which if successful, could result in such market participants engaging in certain predatory trading practices that may have the potential to harm the Fund and its shareholders.

The values of fixed income securities may be affected by changes in the credit rating or financial condition of their issuers. Generally, the lower the credit rating of a security, the higher the degree of risk as to the payment of interest and return of principal.
|
Credit Risk. The issuer of a fixed income security may not be able to make interest and principal payments when due. Generally, the lower the credit rating of a security, the greater the risk that the issuer will default on its obligation. An Underlying Fund could also be delayed or hindered in its enforcement of rights against an issuer, guarantor, or counterparty.
Duration Risk. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities.
Income Risk. The Fund’s income could decline due to falling market interest rates. In a falling interest rate environment, the Fund may be required to invest in Underlying Funds that invest their assets in lower-yielding securities. Because interest rates vary, it is impossible to predict the income or yield of the Fund for any particular period.
Interest Rate Risk. The value of the Fund or an Underlying Fund may fluctuate based upon changes in interest rates and market conditions. As interest rates increase, the value of an Underlying Fund’s income-producing investments may go down. For example, bonds tend to decrease in value when interest rates rise. Debt obligations with longer maturities typically offer higher yields, but are subject to greater price movements as a result of interest rate changes than debt obligations with shorter maturities. Changing interest rates may have unpredictable effects on the markets and an Underlying Fund’s investments and may also affect the liquidity of fixed income securities and instruments held by an Underlying Fund.
Prepayment Risk. The Fund may invest in Underlying Funds that invest in securities that are subject to fluctuations in yield, due to prepayment rates that may be faster or slower than expected.
Rating Risk. If a rating agency gives a debt security a lower rating, the value of the debt security will decline because investors will demand a higher rate of return.

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: “Authorized Participants, Market Makers and Liquidity Providers Concentration Risk,” “Cash Transactions Risk,” “Limitations of Intraday Indicative Value (IIV) Risk,” “Secondary Market Trading Risk,” and “Shares May Trade at Prices Other Than NAV Risk.”
|
| |
o
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as authorized participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares. Further, the Fund is utilizing a novel and unique structure, which may affect the number of entities willing to act as APs, market makers and/or liquidity providers.
|
| |
o
|
Cash Transactions Risk. Unlike traditional ETFs, the securities in the Fund’s basket of securities exchanged for a Creation Unit will not correspond pro rata to the positions in the Fund’s portfolio, and the Fund may effect its creations and redemptions partially or wholly for cash rather than on an in-kind basis. Because of this, the Fund may incur costs such as brokerage costs or be unable to realize certain tax benefits associated with in-kind transfers of portfolio securities that may be realized by other ETFs. These costs may decrease the Fund’s NAV to the extent that the costs are not offset by a transaction fee payable by an AP. Shareholders may be subject to tax on gains they would not otherwise have been subject to and/or at an earlier date than if the Fund had effected redemptions wholly on an in-kind basis.
|
| |
o
|
Limitations of Intraday Indicative Value (IIV) Risk. The Exchange or a market data vendor intends to disseminate the approximate per share value of the Fund’s Portfolio Reference Basket every 15 seconds (the “intraday indicative value” or “IIV”). The IIV should not be viewed as a “real-time” update of the NAV per share of the Fund because (i) the IIV is not be calculated in the same manner as the NAV, which is computed once a day, generally at the end of the business day, (ii) the calculation of NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV, (iii) unlike the calculation of NAV, the IIV does not take into account Fund expenses, and (iv) the IIV is based on the Portfolio Reference Basket and not on the Fund’s Actual Portfolio. The Fund, the Adviser , Sub-Adviser and their affiliates are not involved in, or responsible for, any aspect of the calculation or dissemination of the Fund’s IIV, and the Fund, the Adviser, Sub-Adviser and their affiliates do not make any warranty as to the accuracy of these calculations.

Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, the Nasdaq Stock Market LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. Trading may be halted because of market conditions or for reasons that, in the view of the Exchange, make trading in the Fund inadvisable. These may
|
include: (a) the extent to which trading is not occurring in the securities and/or the financial instruments composing the Portfolio Reference Basket and/or Actual Portfolio; or (b) whether other unusual conditions or circumstances detrimental to the maintenance of a fair and orderly market are present. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
| |
o
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although the Portfolio Reference Basket structure is intended to provide market participants with enough information to allow for an effective arbitrage mechanism that will help to keep the market price of the Fund’s Shares at or close to the Fund’s NAV, there is a risk that market prices for Fund Shares will vary significantly from the Fund’s NAV. This risk is heightened in times of market volatility or periods of steep market declines. This risk may be greater for the Fund than for traditional ETFs that disclose their full portfolio holdings on a daily basis because the publication of the Portfolio Reference Basket does not provide the same level of transparency as the daily publication of the actual portfolio by a traditional ETF. This could cause the Fund’s Shares to have wider bid/ask spreads and larger premiums/discounts than traditional ETFs using the same or similar investment strategies.

Foreign Custody Risk. An Underlying Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Underlying Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Underlying Fund’s ability to recover its assets if
|
a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

Additionally, the trading volume of small-cap company securities may make them more difficult to sell than those of larger companies.

The risk of owning an Underlying Fund generally reflects the risks of owning the underlying investments the Underlying Fund holds. The Fund may incur brokerage fees in connection with its purchase of ETF shares.

High-Yield Securities (“Junk Bond”) Risk. To the extent that a Fund invests in Underlying Funds that invest in high-yield securities and unrated securities of similar credit quality (commonly known as “junk bonds”), the Fund may be subject to greater levels of interest rate and credit risk than funds that do not invest in such securities. Junk bonds are considered predominately speculative with respect to the issuer’s continuing ability to make principal and interest payments. An economic downturn or period of rising interest rates could adversely affect the market for these securities and reduce an Underlying Fund’s ability to sell these securities (liquidity risk). If the issuer of a security is in default with respect to interest or principal payments, the Underlying Fund may lose its entire investment, which will affect the Underlying Fund’s and the Fund’s return.

Counterparty Risk. Some of the derivatives entered into by the Fund are not traded on an exchange but instead will be privately negotiated in the over-the-counter market. This means that these instruments are traded between counterparties based on contractual relationships. Relying on a counterparty exposes the Fund to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the Fund to suffer a loss.

Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the Fund’s yield and may increase the risk that, if followed by rising interest rates, the Fund’s performance will be negatively impacted. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the Fund, resulting in a negative impact on the Fund’s performance and NAV. Any interest rate increases could cause the value of the Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

Options Risk. An option is a type of derivative instrument that gives the holder the right (but not the obligation) to buy (a “call”) or sell (a “put”) an asset in the near future at an agreed upon price prior to the expiration date of the option. The Fund may “cover” a call option by owning the security underlying the option or through other means. The price and value of options can be highly volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including its anticipated volatility, which are affected by national and international fiscal and monetary policies, the time remaining until the expiration of the option contract and economic events, and their use can result in loss if the Adviser is incorrect in its expectation of price fluctuations. The value of the option contracts in which the Fund invests are substantially influenced by the value of the Index, and the Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless.

Price
Participation Risk. The Fund employs an investment strategy that includes
the sale of out-of-the-money put option contracts, which limits the degree to which the Fund
will participate in increases in value experienced by the Index over the call period (typically,
one day, but may range up to one week). This means that if the Index experiences an increase
in value above the strike price of the sold put options during a call period, the Fund will
likely not experience that increase to the same extent and may significantly underperform
the Index over the call period. Additionally, because the Fund is limited in the degree to
which it will participate in increases in value experienced by the Index over each call period,
but has full exposure to any decreases in value experienced by the Index over the call period,
the NAV of the Fund may decrease over any given time period.

The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

|
Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the Fund’s yield and may increase the risk that, if followed by rising interest rates, the Fund’s performance will be negatively impacted. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the Fund, resulting in a negative impact on the Fund’s performance and NAV. Any interest rate increases could cause the value of the Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

Options Risk. An option is a type of derivative instrument that gives the holder the right (but not the obligation) to buy (a “call”) or sell (a “put”) an asset in the near future at an agreed upon price prior to the expiration date of the option. The Fund may “cover” a call option by owning the security underlying the option or through other means. The price and value of options can be highly volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including its anticipated volatility, which are affected by national and international fiscal and monetary policies, the time remaining until the expiration of the option contract and economic events, and their use can result in loss if the Adviser is incorrect in its expectation of price fluctuations. The value of the option contracts in which the Fund invests are substantially influenced by the value of the Index, and the Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless.

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: “Authorized Participants, Market Makers and Liquidity Providers Concentration Risk,” “Cash Transactions Risk,” “Secondary Market Trading Risk,” and “Shares May Trade at Prices Other Than NAV Risk.”
|
| |
o
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as authorized participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other
|
entities step forward to perform their functions. These events, among others, may lead to the Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Shares. Further, the Fund is utilizing a novel and unique structure, which may affect the number of entities willing to act as APs, market makers and/or liquidity providers.
| |
o
|
Cash Transactions Risk. Unlike certain ETFs, the Fund may effect its creations and redemptions partially or wholly for cash rather than on an in-kind basis. Because of this, the Fund may incur costs such as brokerage costs or be unable to realize certain tax benefits associated with in-kind transfers of portfolio securities that may be realized by other ETFs. These costs may decrease the Fund’s NAV to the extent that the costs are not offset by a transaction fee payable by an AP. Shareholders may be subject to tax on gains they would not otherwise have been subject to and/or at an earlier date than if the Fund had effected redemptions wholly on an in-kind basis.
|
| |
o
|
Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, The Nasdaq Stock Market LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. Trading may be halted because of market conditions or for reasons that, in the view of the Exchange, make trading in the Fund inadvisable. These may include: (a) the extent to which trading is not occurring in the securities and/or the financial instruments composing the Fund’s Portfolio; or (b) whether other unusual conditions or circumstances detrimental to the maintenance of a fair and orderly market are present. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
o
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. There is a risk that market prices for Shares will vary significantly from the Fund’s NAV. This risk is heightened in times of market volatility or periods of steep market declines.

Fixed Income Risk. Fixed income securities, such as U.S. Treasuries, or derivatives based on fixed income securities, are subject to credit risk and interest rate risk. Credit risk, as described more fully herein, refers to the possibility that the issuer of a debt security will be unable to make interest payments or repay principal when it becomes due. Interest rate risk refers to fluctuations in the value of a debt security resulting from changes in the general level of interest rates. Prices of fixed income securities tend to move inversely with changes in interest rates. Typically, a rise in rates will adversely affect fixed income security prices and, accordingly, the Fund’s returns and share price. In addition, the Fund may be subject to “call” risk, which is the risk that during a period of falling interest rates the issuer may redeem a security by repaying it early (which may reduce the Fund’s income if the proceeds are reinvested at lower interest rates), and “extension” risk, which occurs during a rising interest rate environment because certain obligations will be paid off by an issuer more slowly than anticipated (causing the value of those securities held by the Fund to fall).

The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments, higher price volatility, lack of availability, counterparty risk, liquidity, valuation, and legal restrictions.

High Portfolio Turnover Risk. The risk that when investing on a shorter-term basis, the Fund may as a result trade more frequently and incur higher levels of brokerage fees and commissions and cause higher levels of current tax liability to shareholders of the Fund. A portfolio turnover rate of 100% is considered to be high. The Adviser may engage in active trading, and will not consider portfolio turnover a limiting factor in making decisions for the Fund.

Options Risk. An option is a type of derivative instrument that gives the holder the right (but not the obligation) to buy (a “call”) or sell (a “put”) an asset in the near future at an agreed upon price prior to the expiration date of the option. The Fund may “cover” a call option by owning the security underlying the option or through other means. The price and value of options can be highly volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including its anticipated volatility, which are affected by national and international fiscal and monetary policies, the time remaining until the expiration of the option contract and economic events, and their use can result in loss if the Adviser is incorrect in its expectation of price fluctuations. The value of the option contracts in which the Fund invests are substantially influenced by the value of the Index, and the Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless.

●
|
ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: “Authorized Participants, Market Makers and Liquidity Providers Concentration Risk,” “Cash Transactions Risk,” “Secondary Market Trading Risk,” and “Shares May Trade at Prices Other Than NAV Risk.”
|
| |
o
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares in the secondary market, and you may receive less (or more) than NAV when you sell those Shares
|
in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Shares.
| |
o
|
Cash Transactions Risk. Unlike certain ETFs, the Fund may effect its creations and redemptions partially or wholly for cash rather than on an in-kind basis. Because of this, the Fund may incur costs such as brokerage costs or be unable to realize certain tax benefits associated with in-kind transfers of portfolio securities that may be realized by other ETFs. These costs may decrease the Fund’s NAV to the extent that the costs are not offset by a transaction fee payable by an AP. Shareholders may be subject to tax on gains they would not otherwise have been subject to and/or at an earlier date than if the Fund had effected redemptions wholly on an in-kind basis.
|
| |
o
|
Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, the The Nasdaq Stock Market LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. Trading may be halted because of market conditions or for reasons that, in the view of the Exchange, make trading in the Fund inadvisable. These may include: (a) the extent to which trading is not occurring in the securities and/or the financial instruments composing the Fund’s Portfolio; or (b) whether other unusual conditions or circumstances detrimental to the maintenance of a fair and orderly market are present. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
o
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. There is a risk that market prices for Fund Shares will vary significantly from the Fund’s NAV. Where all or portion of the Fund’s underlying securities trade in a foreign market that is closed when the market in which the Fund’s Shares are listed is open for trading, there may be changes between the last quote of the underlying securities’ value in the closed foreign market and the value of such underlying securities during the Fund’s domestic trading day.

This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stocks and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

Futures Risk: The successful use of futures contracts draws upon the Adviser’s skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of futures contracts are (a) the imperfect correlation between the change in market value of instruments held by the Fund and the price of the futures contract; (b) possible lack of a liquid secondary market, and possible regulatory position limits and restrictions for a futures contract and the resulting inability to close a futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the Adviser’s inability to predict correctly the direction of securities prices, equity indices, interest rates, currency exchange rates and other economic factors; (e) the possibility that the counterparty will default in the performance of its obligations; and (f) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so.

| SGI Enhanced Nasdaq-100 ETF | Valuation Risk |
|
| Prospectus [Line Items] |
|
| Risk [Text Block] |
| |
●
|
Valuation Risk. During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value its options contracts becomes more difficult and the judgment of the Adviser, as the Fund’s valuation designee, employing the fair value procedures adopted by the Board of Directors (the “Board”) of the RBB Fund, Inc. (the “Company”), may play a greater role in the valuation of the Fund’s holdings due to reduced availability of reliable objective pricing data. Consequently, while such determinations may be made in good faith, it may nevertheless be more difficult for the Fund to accurately assign a daily value. In the event an investment may need to be fair valued, the valuation involves subjectivity and there is a risk that the Fund may not be able to sell an investment at the price assigned to it in accordance with the Company’s policies and procedures in accordance with Rule 2a-5 of the 1940 Act (“Rule 2a-5”).

Affiliated Fund Risk. Affiliated fund risk is the risk that the Adviser may select investments for the Fund based on its own financial interests rather than the Fund’s interests. The Adviser may be subject to potential conflicts of interest in selecting the Underlying Funds because the fees paid to the Adviser by some affiliated Underlying Funds may be higher than other Underlying Funds or the Underlying Funds may be in need of assets to enhance their appeal to other investors, liquidity and trading and/or to enable them to carry out their investment strategies. However, the Adviser is a fiduciary to the Fund and is legally obligated to act in the Fund’s best interest when selecting Underlying Funds.

There is a risk that such large shareholders or that the Fund’s shareholders generally may redeem all or a substantial portion of their investments in the Fund in a short period of time, which could have a significant negative impact on the Fund’s NAV, liquidity, and brokerage costs. Large redemptions could also result in tax consequences to shareholders and impact the Fund’s ability to implement its investment strategy.

|
investments, as well as to the other investment companies’ expenses. An ETF may trade in the secondary market at a price below the value of its underlying portfolio and may not be liquid. An actively managed ETF’s performance will reflect its adviser’s ability to make investment decisions that are suited to achieving the ETF’s investment objectives. A passively managed ETF may not replicate the performance of the index it intends to track.

|
| Prospectus [Line Items] |

|
Price Participation Risk. The Fund employs an investment strategy that includes the sale of out-of-the-money put option contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Index over the call period (typically, one day, but may range up to one week). This means that if the Index experiences an increase in value above the strike price of the sold put options during a call period, the Fund will likely not experience that increase to the same extent and may significantly underperform the Index over the call period. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Index over each call period, but has full exposure to any decreases in value experienced by the Index over the call period, the NAV of the Fund may decrease over any given time period.

Inflation and Deflation Risk. Inflation risk is the risk that the value of assets or income from investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the Fund’s shares and any distributions thereon may decline. Inflation rates may change frequently and significantly as a result of various factors, including unexpected shifts in the domestic or global economy and changes in economic policies, and the Fund’s investments may not keep pace with inflation, which may result in losses to the
|
Fund’s shareholders. Deflation risk is the risk that the prices of goods and services in the U.S. and many foreign economies may decline over time. Deflation may have an adverse effect on stock prices and the creditworthiness of issuers and may make defaults on debt more likely. If a country’s economy slips into a deflationary pattern, it could last for a prolonged period and be difficult to reverse.

The value of money market instruments tends to fall when current interest rates rise. Money market instruments are generally less sensitive to interest rate changes than longer-term securities.

The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders.

Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Shares.

Cash Transactions Risk. Unlike certain ETFs, the Fund may effect its creations and redemptions partially or wholly for cash rather than on an in-kind basis. Because of this, the Fund may incur costs such as brokerage costs or be unable to realize certain tax benefits associated with in-kind transfers of portfolio securities that may be realized by other ETFs. These costs may decrease the Fund’s NAV to the extent that the costs are not offset by a transaction fee payable by an AP. Shareholders may be subject to tax on gains they would not otherwise have been subject to and/or at an earlier date than if the Fund had effected redemptions wholly on an in-kind basis.

o
|
Appreciated Securities Risk. The Fund holds certain securities that were exchanged into the Fund at its inception in 1976. The cost, for income tax purposes, of such securities is the tax basis of the individual investor at the time of that exchange. The basis of those securities may be relatively low, and it is therefore possible that the Fund will recognize significant gain if it sells those securities.

Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, The Nasdaq Stock Market LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted.

This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stocks and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

Valuation Risk. During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value its options contracts becomes more difficult and the judgment of the Adviser, as the Fund’s valuation designee, employing the fair value procedures adopted by the Board of the Company, may play a greater role in the valuation of the Fund’s holdings due to reduced availability of reliable objective pricing data. Consequently, while such determinations may be made in good faith, it may nevertheless be more difficult for the Fund to accurately assign a daily value. In the event an investment may need
|
to be fair valued, the valuation involves subjectivity and there is a risk that the Fund may not be able to sell an investment at the price assigned to it in accordance with the Company’s policies and procedures in accordance with Rule 2a-5 of the 1940 Act (“Rule 2a-5”).

Affiliated Fund Risk. Affiliated fund risk is the risk that the Adviser may select investments for the Fund based on its own financial interests rather than the Fund’s interests. The Adviser may be subject to potential conflicts of interest in selecting the Underlying Funds because the fees paid to the Adviser by some affiliated Underlying Funds may be higher than other Underlying Funds or the Underlying Funds may be in need of assets to enhance their appeal to other investors, liquidity and trading and/or to enable them to carry out their investment strategies.

Investment Companies and ETFs Risk. The Fund’s investment performance may be affected by the investment performance of the underlying funds in which the Fund may invest. Investing in other investment companies, including ETFs, may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. The risk of owning an investment company or ETF generally reflects the risks of owning the underlying investments the investment company or ETF holds. The Fund may incur brokerage fees in connection with its purchase of ETF shares. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their NAV.

Over-the-Counter Risk. Securities traded on over-the-counter (“OTC”) markets are not listed and traded on an organized exchange such as the New York Stock Exchange (“NYSE”). Generally, the volume of trading in an unlisted or OTC common stock is less than the volume of trading in an exchange-listed stock. As a result, the market liquidity of some stocks in which the Fund invests may not be as great as that of exchange-listed stocks and, if the Fund were to dispose of such stocks, the Fund may have to offer the shares at a discount from recent prices or sell the shares in small lots over an extended period of time.

Price Participation Risk. The Fund employs an investment strategy that includes the sale of out-of-the-money put and call option contracts, which does not allow the Fund to participate in increases in value experienced by the Index over the call period (typically, one day, but may range up to one week). This means that if the Index experiences an increase in value above the strike price of the sold put options during a call period, the Fund will not experience that increase and may underperform the Index over the call period. Additionally, because the Fund does not participate in increases in value experienced by the Index from selling options over each call period, the NAV of the Fund may decrease over any given time period based on the change in the underlying value of the puts or calls sold.

Inflation and Deflation Risk. Inflation risk is the risk that the value of assets or income from investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the Fund’s shares and any distributions thereon may decline. Inflation rates may change frequently and significantly as a result of various factors, including unexpected shifts in the domestic or global economy and changes in economic policies, and the Fund’s investments may not keep pace with inflation, which may result in losses to the Fund’s shareholders. Deflation risk is the risk that the prices of goods and services in the U.S. and many foreign economies may decline over time. Deflation may have an adverse effect on stock prices and the creditworthiness of issuers and may make defaults on debt more likely. If a country’s economy slips into a deflationary pattern, it could last for a prolonged period and be difficult to reverse.

Temporary Investments. The Fund may depart from its principal investment strategy in response to adverse market, economic, political or other conditions by taking a temporary defensive position (up to 100% of its assets) in cash, cash equivalents and all types of money market and short-term debt securities. The value of money market instruments tends to fall when current interest rates rise. Money market instruments are generally less sensitive to interest rate changes than longer-term securities. If the Fund were to take a temporary defensive position, it may be unable to achieve its investment objective for a period of time.

|
Covered Call Strategy Risk. The Fund may write covered call options on securities as a means of increasing the yield on its assets and as a means of providing limited protection against decreases in its market value. When the Fund writes an option, if the underlying securities do not increase or decrease to a price level that would make the exercise of the option profitable to the holder thereof, the option generally will expire without being exercised and the Fund will realize as profit the premium received for such option. When a call option of which the Fund is the writer is exercised, the Fund will be required to sell the underlying securities to the option holder at the strike price, and will not participate in any increase in the price of such securities above the strike price. When a put option of which the Fund is the writer is exercised, the Fund will be required to purchase the underlying securities at a price in excess of the market value of such securities. The Fund will have no control over the exercise of the option by the option holder and may lose the benefit from any capital appreciation on the underlying security. Many factors may influence the option holder’s decision to exercise the option, including, but not limited to, the value of the underlying security, price volatility, dividend yield, and interest rates. To the extent that these factors increase the call option’s value, the option holder is more likely to exercise the option, which may negatively affect the Fund.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyberattacks or other cyber-failures.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the Fund’s yield and may increase the risk that, if followed by rising interest rates, the Fund’s performance will be negatively impacted. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the Fund, resulting in a negative impact on the Fund’s performance and NAV. Any interest rate increases could cause the value of the Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
|
| |
●
|
Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in Fund redemption requests, including requests from shareholders who may own a significant percentage of the Fund’s Shares, which may be triggered by market turmoil or an increase in interest rates, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions.

In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the Fund’s yield and may increase the risk that, if followed by rising interest rates, the Fund’s performance will be negatively impacted. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the Fund, resulting in a negative impact on the Fund’s performance and NAV. Any interest rate increases could cause the value of the Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors including economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. As a result, an investor could lose money over short or long periods of time.

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
|
| |
●
|
Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in Fund redemption requests, including requests from shareholders who may own a significant percentage of the Fund’s Shares, which may be triggered by market turmoil or an increase in interest rates, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions.

The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but
|
will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the Fund’s yield and may increase the risk that, if followed by rising interest rates, the Fund’s performance will be negatively impacted. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the Fund, resulting in a negative impact on the Fund’s performance and NAV. Any interest rate increases could cause the value of the Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors including economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. As a result, an investor could lose money over short or long periods of time.

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
|
| |

|
Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in Fund redemption requests, including requests from shareholders who may own a significant percentage of the fund’s shares, which may be triggered by market turmoil or an increase in interest rates, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions.

The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders.

The active and frequent trading of the Fund’s portfolio securities may result in increased transaction costs to the Fund, including brokerage commissions, dealer mark-ups and other transaction costs, which could reduce the Fund’s return.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but
|
will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the Fund’s yield and may increase the risk that, if followed by rising interest rates, the Fund’s performance will be negatively impacted. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the Fund, resulting in a negative impact on the Fund’s performance and NAV. Any interest rate increases could cause the value of the Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors including economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. As a result, an investor could lose money over short or long periods of time.

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
|
| |
●
|
Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in Fund redemption requests, including requests from shareholders who may own a significant percentage of the Fund’s Shares, which may be triggered by market turmoil or an increase in interest rates, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions.

Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

High Portfolio Turnover Risk. In seeking to track the Underlying Index, the Fund may incur relatively high portfolio turnover. The active and frequent trading of the Fund’s portfolio securities may result in increased transaction costs to the Fund, including brokerage commissions, dealer mark-ups and other transaction costs, which could reduce the Fund’s return.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the Fund’s yield and may increase the risk that, if followed by rising interest rates, the Fund’s performance will be negatively impacted. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the Fund, resulting in a negative impact on the Fund’s performance and NAV. Any interest rate increases could cause the value of the Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors including economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. As a result, an investor could lose money over short or long periods of time.

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Funds. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
|
| |
●
|
Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in Fund redemption requests, including requests from shareholders who may own a significant percentage of the Fund’s Shares, which may be triggered by market turmoil or an increase in interest rates, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions.

The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser.

Cyber security risk is the risk of an unauthorized breach and access to the Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

High Portfolio Turnover Risk. In seeking to track the Underlying Index, the Fund may incur relatively high portfolio turnover. The active and frequent trading of the Fund’s portfolio securities may result in increased transaction costs to the Fund, including brokerage commissions, dealer mark-ups and other transaction costs, which could reduce the Fund’s return.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the Fund’s yield and may increase the risk that, if followed by rising interest rates, the Fund’s performance will be negatively impacted. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the Fund, resulting in a negative impact on the Fund’s performance and NAV. Any interest rate increases could cause the value of the Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors including economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. As a result, an investor could lose money over short or long periods of time.

|
ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
|
| |
●
|
Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in Fund redemption requests, including requests from shareholders who may own a significant percentage of the Fund’s Shares, which may be triggered by market turmoil or an increase in interest rates, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions.

Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

Reverse repurchase agreements involve the risk that the investment return earned by the Fund (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Fund will decline below the price the Fund is obligated to pay to repurchase the securities, and that the other party may fail to return the securities in a timely manner or at all.

The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting the Fund’s third-party service providers, the Underlying Funds, and the Underlying Funds’ third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund, the Underlying Funds, or their respective advisers. Successful cyber-attacks or other cyber-failures or events affecting the Fund, the Underlying Funds or third-party service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund or the Underlying Funds invest are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyberattacks or other cyber failures.

Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.

Because of this, the Fund may incur certain costs, such as brokerage costs, or be unable to realize certain tax benefits associated with in-kind transfers of portfolio securities that may be realized by other ETFs. These costs may decrease the Fund’s NAV to the extent that the costs are not offset by a transaction fee payable by an AP.

Non-U.S. Issuers Risk. Securities issued by non-U.S. issuers carry different risks from securities issued by U.S. issuers. These risks include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability, regulatory and economic differences, and potential restrictions on the flow of international capital.

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in Fund redemption requests, including requests from shareholders who may own a significant percentage of the Fund’s Shares, which may be triggered by market turmoil or an increase in interest rates, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions. In addition, the Fund may be subject to risks associated with investments in senior non-preferred bonds (sometimes referred to as a “bail-in bonds”), which are debt securities issued by financial institutions that can be converted into equity securities if such conversion is mandated by a financial institution’s regulatory authority due to the financial institution facing the possibility of bankruptcy. The mandatory conversion of a bail-in bond into an equity security may result in a reduction in value of the security and, if the Fund holds such security when the conversion occurs, the Fund’s performance may be negatively impacted.

Corporate bonds may be either secured or unsecured. Corporate bonds may have more speculative characteristics in their ability to repay principal and interest than other types of fixed income securities, such as government securities. Corporate bonds contain elements of both interest-rate risk and credit risk and are subject to the risks associated with other debt securities, among other risks. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates and may also be affected by the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the marketplace. There is a risk that the issuers of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by an instrument.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Underlying Funds, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting the Fund’s third-party service providers, the Underlying Funds, and the Underlying Funds’ third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund, the Underlying Funds, or their respective advisers. Successful cyber-attacks or other cyber-failures or events affecting the Fund, the Underlying Funds or third-party service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund or the Underlying Funds invest are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyberattacks or other cyber failures.

High Portfolio Turnover Risk. In seeking to track the Underlying Index, the Fund may incur relatively high portfolio turnover.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund or an Underlying Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s or an Underlying Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the Fund’s or an Underlying Fund’s yield and may increase the risk that, if followed by rising interest rates, the Fund’s or Underlying Fund’s performance will be negatively impacted. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the Fund or an Underlying Fund, resulting in a negative impact on the Fund’s performance and NAV. Any interest rate increases could cause the value of the Fund’s or an Underlying Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the Fund or an Underlying Fund, which may force the Fund or Underlying Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

●
|
ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Funds. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, there may be significantly diminished trading in Fund Shares, Fund Shares may trade at a material discount to net asset value (“NAV”), and Fund Shares may possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
|
| |
●
|
Secondary Market Trading Risk. Although Shares are intended to be listed on a national securities exchange (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. To the extent the Fund invests in Underlying Funds, which are also ETFs, the Fund will be further exposed to ETF risks.
|
| |
●
|
Cash Transactions Risk. Unlike certain ETFs, the Fund may effect its creations and redemptions partially or wholly for cash, rather than on an in-kind basis. Because of this, the Fund may incur certain costs, such as brokerage costs, or be unable to realize certain tax benefits associated with in-kind transfers of portfolio securities that may be realized by other ETFs. These costs may decrease the Fund’s NAV to the extent that the costs are not offset by a transaction fee payable by an AP. Shareholders may be subject to tax on gains they would not otherwise have been subject to and/or at an earlier date than if the Fund had effected redemptions wholly on an in-kind basis.

Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the Fund, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

Cyber security risk is the risk of an unauthorized breach and access to the Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Underlying Funds, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting the Fund’s third-party service providers, the Underlying Funds, and the Underlying Funds’ third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund, the Underlying Funds, or their respective advisers. Successful cyber-attacks or other cyber-failures or events affecting the Fund, the Underlying Funds or third-party service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund or the Underlying Funds invest are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyberattacks or other cyber failures.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund or an Underlying Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s or an Underlying Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the Fund’s or an Underlying Fund’s yield and may increase the risk that, if followed by rising interest rates, the Fund’s or Underlying Fund’s performance will be negatively impacted. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the Fund or an Underlying Fund, resulting in a negative impact on the Fund’s performance and NAV. Any interest rate increases could cause the value of the Fund’s or an Underlying Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the Fund or an Underlying Fund, which may force the Fund or Underlying Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, there may be significantly diminished trading in Fund Shares, Fund Shares may trade at a material discount to net asset value (“NAV”), and Fund Shares may possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s
|
shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in ETF Shares.
| |
●
|
Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, The Nasdaq Stock Market LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. To the extent the Fund invests in Underlying Funds, which are also ETFs, the Fund will be further exposed to ETF risks.
|
| |
●
|
Cash Transactions Risk. Unlike certain ETFs, the Fund may effect its creations and redemptions partially or wholly for cash, rather than on an in-kind basis. Because of this, the Fund may incur certain costs, such as brokerage costs, or be unable to realize certain tax benefits associated with in-kind transfers of portfolio securities that may be realized by other ETFs. These costs may decrease the Fund’s NAV to the extent that the costs are not offset by a transaction fee payable by an AP. Shareholders may be subject to tax on gains they would not otherwise have been subject to and/or at an earlier date than if the Fund had effected redemptions wholly on an in-kind basis.

Tracking Error Risk. The Fund may be subject to tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the Fund, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in Fund redemption requests, including requests from shareholders who may own a significant percentage of the Fund’s Shares, which may be triggered by market turmoil or an increase in interest rates, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions. In addition, the Fund may be subject to risks associated with investments in senior non-preferred bonds (sometimes referred to as a “bail-in bonds”), which are debt securities issued by financial institutions that can be converted into equity securities if such conversion is mandated by a financial institution’s regulatory authority due to the financial institution facing the possibility of bankruptcy. The mandatory conversion of a bail-in bond into an equity security may result in a reduction in value of the security and, if the Fund holds such security when the conversion occurs, the Fund’s performance may be negatively impacted.

Reverse repurchase agreements involve the risk that the investment return earned by the Fund (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Fund will decline below the price the Fund is obligated to pay to repurchase the securities, and that the other party may fail to return the securities in a timely manner or at all.

Corporate Bonds Risk. Corporate bonds are typically issued by public or private companies to finance their operations and are distinct from debt securities issued by a government or its agencies. Corporate bonds may be either secured or unsecured. Corporate bonds may have more speculative characteristics in their ability to repay principal and interest than other types of fixed income securities, such as government securities. Corporate bonds contain elements of both interest-rate risk and credit risk and are subject to the risks associated with other debt securities, among other risks. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates and may also be affected by the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the marketplace. There is a risk that the issuers of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by an instrument.

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in Fund redemption requests, including requests from shareholders who may own a significant percentage of the Fund’s Shares, which may be triggered by market turmoil or an increase in interest rates, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions. In addition, the Fund may be subject to risks associated with investments in senior non-preferred bonds (sometimes referred to as a “bail-in bonds”), which are debt securities issued by financial institutions that can be converted into equity securities if such conversion is mandated by a financial institution’s regulatory authority due to the financial institution facing the possibility of bankruptcy. The mandatory conversion of a bail-in bond into an equity security may result in a reduction in value of the security and, if the Fund holds such security when the conversion occurs, the Fund’s performance may be negatively impacted.

Reverse repurchase agreements involve the risk that the investment return earned by the Fund (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Fund will decline below the price the Fund is obligated to pay to repurchase the securities, and that the other party may fail to return the securities in a timely manner or at all.

Corporate bonds may be either secured or unsecured. Corporate bonds may have more speculative characteristics in their ability to repay principal and interest than other types of fixed income securities, such as government securities. Corporate bonds contain elements of both interest-rate risk and credit risk and are subject to the risks associated with other debt securities, among other risks. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates and may also be affected by the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the marketplace. There is a risk that the issuers of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by an instrument.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Underlying Funds, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting the Fund’s third-party service providers, the Underlying Funds, and the Underlying Funds’ third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund, the Underlying Funds, or their respective advisers. Successful cyber-attacks or other cyber-failures or events affecting the Fund, the Underlying Funds or third-party service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund or the Underlying Funds invest are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyberattacks or other cyber failures.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund or an Underlying Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s or an Underlying Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the Fund’s or an Underlying Fund’s yield and may increase the risk that, if followed by rising interest rates, the Fund’s or Underlying Fund’s performance will be negatively impacted. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the Fund or an Underlying Fund, resulting in a negative impact on the Fund’s performance and NAV. Any interest rate increases could cause the value of the Fund’s or an Underlying Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the Fund or an Underlying Fund, which may force the Fund or Underlying Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

|
ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, there may be significantly diminished trading in Fund Shares, Fund Shares may trade at a material discount to net asset value (“NAV”), and Fund Shares may possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s
|
shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
| |
●
|
Secondary Market Trading Risk. Although Shares are intended to be listed on a national securities exchange (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. To the extent the Fund invests in Underlying Funds, which are also ETFs, the Fund will be further exposed to ETF risks.
|
| |
●
|
Cash Transactions Risk. Unlike certain ETFs, the Fund may effect its creations and redemptions partially or wholly for cash, rather than on an in-kind basis. Because of this, the Fund may incur certain costs, such as brokerage costs, or be unable to realize certain tax benefits associated with in-kind transfers of portfolio securities that may be realized by other ETFs. These costs may decrease the Fund’s NAV to the extent that the costs are not offset by a transaction fee payable by an AP. Shareholders may be subject to tax on gains they would not otherwise have been subject to and/or at an earlier date than if the Fund had effected redemptions wholly on an in-kind basis.

The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in Fund redemption requests, including requests from shareholders who may own a significant percentage of the fund’s shares, which may be triggered by market turmoil or an increase in interest rates, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions. In addition, the Fund may be subject to risks associated with investments in senior non-preferred bonds (sometimes referred to as a “bail-in bonds”), which are debt securities issued by financial institutions that can be converted into equity securities if such conversion is mandated by a financial institution’s regulatory authority due to the financial institution facing the possibility of bankruptcy. The mandatory conversion of a bail-in bond into an equity security may result in a reduction in value of the security and, if the Fund holds such security when the conversion occurs, the Fund’s performance may be negatively impacted.

Corporate Bonds Risk. Corporate bonds are typically issued by public or private companies to finance their operations and are distinct from debt securities issued by a government or its agencies. Corporate bonds may be either secured or unsecured. Corporate bonds may have more speculative characteristics in their ability to repay principal and interest than other types of fixed income securities, such as government securities. Corporate bonds contain elements of both interest-rate risk and credit risk and are subject to the risks associated with other debt securities, among other risks. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates and may also be affected by the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the marketplace. There is a risk that the issuers of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by an instrument.

Cyber security risk is the risk of an unauthorized breach and access to the Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Underlying Funds, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting the Fund’s third-party service providers, the Underlying Funds, and the Underlying Funds’ third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund, the Underlying Funds, or their respective advisers. Successful cyber-attacks or other cyber-failures or events affecting the Fund, the Underlying Funds or third-party service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund or the Underlying Funds invest are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyberattacks or other cyber failures.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund or an Underlying Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s or an Underlying Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the Fund’s or an Underlying Fund’s yield and may increase the risk that, if followed by rising interest rates, the Fund’s or Underlying Fund’s performance will be negatively impacted. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the Fund or an Underlying Fund, resulting in a negative impact on the Fund’s performance and NAV. Any interest rate increases could cause the value of the Fund’s or an Underlying Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the Fund or an Underlying Fund, which may force the Fund or Underlying Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

Management Risk.

|
ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, there may be significantly diminished trading in Fund Shares, Fund Shares may trade at a material discount to net asset value (“NAV”), and Fund Shares may possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s
|
shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
| |
●
|
Secondary Market Trading Risk. Although Shares are intended to be listed on a national securities exchange (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. To the extent the Fund invests in Underlying Funds, which are also ETFs, the Fund will be further exposed to ETF risks.
|
| |
●
|
Cash Transactions Risk. Unlike certain ETFs, the Fund may effect its creations and redemptions partially or wholly for cash, rather than on an in-kind basis. Because of this, the Fund may incur certain costs, such as brokerage costs, or be unable to realize certain tax benefits associated with in-kind transfers of portfolio securities that may be realized by other ETFs. These costs may decrease the Fund’s NAV to the extent that the costs are not offset by a transaction fee payable by an AP. Shareholders may be subject to tax on gains they would not otherwise have been subject to and/or at an earlier date than if the Fund had effected redemptions wholly on an in-kind basis.

Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the Fund, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund or an Underlying Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s or an Underlying Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the Fund’s or an Underlying Fund’s yield and may increase the risk that, if followed by rising interest rates, the Fund’s or Underlying Fund’s performance will be negatively impacted. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the Fund or an Underlying Fund, resulting in a negative impact on the Fund’s performance and NAV. Any interest rate increases could cause the value of the Fund’s or an Underlying Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the Fund or an Underlying Fund, which may force the Fund or Underlying Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors including economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. As a result, an investor could lose money over short or long periods of time.

|
ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, there may be significantly diminished trading in Fund Shares, Fund Shares may trade at a material discount to net asset value (“NAV”), and Fund Shares may possibly face delisting: (i) APs exit the business or otherwise become unable to process
|
creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
| |
●
|
Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. To the extent the Fund invests in Underlying Funds, which are also ETFs, the Fund will be further exposed to ETF risks.
|
| |
●
|
Cash Transactions Risk. Unlike certain ETFs, the Fund may effect its creations and redemptions partially or wholly for cash, rather than on an in-kind basis. Because of this, the Fund may incur certain costs, such as brokerage costs, or be unable to realize certain tax benefits associated with in-kind transfers of portfolio securities that may be realized by other ETFs. These costs may decrease the Fund’s NAV to the extent that the costs are not offset by a transaction fee payable by an AP. Shareholders may be subject to tax on gains they would not otherwise have been subject to and/or at an earlier date than if the Fund had effected redemptions wholly on an in-kind basis.

|
Tracking Error Risk. The Fund may be subject to tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the Fund, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

Affiliated fund risk is the risk that the Adviser may select investments for the Fund based on its own financial interests or other business considerations rather than the Fund’s interests. The Adviser may be subject to potential conflicts of interest in selecting the Underlying Funds because the Underlying Funds pay an advisory fee to the Adviser based on their assets, the fees paid to the Adviser by some affiliated Underlying Funds may be higher than other Underlying Funds or the Underlying Funds may be in need of assets to enhance their appeal to other investors, liquidity and trading and/or to enable them to carry out their investment strategies. However, the Adviser is a fiduciary to the Fund and is legally obligated to act in the Fund’s best interest when selecting Underlying Funds.

|
Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in Fund redemption requests, including requests from shareholders who may own a significant percentage of the Fund’s Shares, which may be triggered by market turmoil or an increase in interest rates, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions. In addition, the Fund may be subject to risks associated with investments in senior non-preferred bonds (sometimes referred to as a “bail-in bonds”), which are debt securities issued by financial institutions that can be converted into equity securities if such conversion is mandated by a financial institution’s regulatory authority due to the financial institution facing the possibility of bankruptcy. The mandatory conversion of a bail-in bond into an equity security may result in a reduction in value of the security and, if the Fund holds such security when the conversion occurs, the Fund’s performance may be negatively impacted.

Reverse repurchase agreements involve the risk that the investment return earned by the Fund (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Fund will decline below the price the Fund is obligated to pay to repurchase the securities, and that the other party may fail to return the securities in a timely manner or at all.

Corporate Bonds Risk. Corporate bonds are typically issued by public or private companies to finance their operations and are distinct from debt securities issued by a government or its agencies. Corporate bonds may be either secured or unsecured. Corporate bonds may have more speculative characteristics in their ability to repay principal and interest than other types of fixed income securities, such as government securities. Corporate bonds contain elements of both interest-rate risk and credit risk and are subject to the risks associated with other debt securities, among other risks. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates and may also be affected by the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the marketplace. There is a risk that the issuers of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by an instrument.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Underlying Funds, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting the Fund’s third-party service providers, the Underlying Funds, and the Underlying Funds’ third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund, the Underlying Funds, or their respective advisers. Successful cyber-attacks or other cyber-failures or events affecting the Fund, the Underlying Funds or third-party service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund or the Underlying Funds invest are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyberattacks or other cyber failures.

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in Fund redemption requests, including requests from shareholders who may own a significant percentage of the fund’s shares, which may be triggered by market turmoil or an increase in interest rates, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions. In addition, the Fund may be subject to risks associated with investments in senior non-preferred bonds (sometimes referred to as a “bail-in bonds”), which are debt securities issued by financial institutions that can be converted into equity securities if such conversion is mandated by a financial institution’s regulatory authority due to the financial institution facing the possibility of bankruptcy. The mandatory conversion of a bail-in bond into an equity security may result in a reduction in value of the security and, if the Fund holds such security when the conversion occurs, the Fund’s performance may be negatively impacted.

Reverse repurchase agreements involve the risk that the investment return earned by the Fund (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Fund will decline below the price the Fund is obligated to pay to repurchase the securities, and that the other party may fail to return the securities in a timely manner or at all.

Corporate Bonds Risk. Corporate bonds are typically issued by public or private companies to finance their operations and are distinct from debt securities issued by a government or its agencies. Corporate bonds may be either secured or unsecured. Corporate bonds may have more speculative characteristics in their ability to repay principal and interest than other types of fixed income securities, such as government securities. Corporate bonds contain elements of both interest-rate risk and credit risk and are subject to the risks associated with other debt securities, among other risks. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates and may also be affected by the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the marketplace. There is a risk that the issuers of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by an instrument.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Underlying Funds, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting the Fund’s third-party service providers, the Underlying Funds, and the Underlying Funds’ third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund, the Underlying Funds, or their respective advisers. Successful cyber-attacks or other cyber-failures or events affecting the Fund, the Underlying Funds or third-party service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund or the Underlying Funds invest are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyberattacks or other cyber failures.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund or an Underlying Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s or an Underlying Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the Fund’s or an Underlying Fund’s yield and may increase the risk that, if followed by rising interest rates, the Fund’s or Underlying Fund’s performance will be negatively impacted. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the Fund or an Underlying Fund, resulting in a negative impact on the Fund’s performance and NAV. Any interest rate increases could cause the value of the Fund’s or an Underlying Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the Fund or an Underlying Fund, which may force the Fund or Underlying Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, there may be significantly diminished trading in Fund Shares, Fund Shares may trade at a material discount to net asset value (“NAV”), and Fund Shares may possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s
|
shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
| |
●
|
Secondary Market Trading Risk. Although Shares are intended to be listed on a national securities exchange (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. To the extent the Fund invests in Underlying Funds, which are also ETFs, the Fund will be further exposed to ETF risks.
|
| |
●
|
Cash Transactions Risk. Unlike certain ETFs, the Fund may effect its creations and redemptions partially or wholly for cash, rather than on an in-kind basis. Because of this, the Fund may incur certain costs, such as brokerage costs, or be unable to realize certain tax benefits associated with in-kind transfers of portfolio securities that may be realized by other ETFs. These costs may decrease the Fund’s NAV to the extent that the costs are not offset by a transaction fee payable by an AP. Shareholders may be subject to tax on gains they would not otherwise have been subject to and/or at an earlier date than if the Fund had effected redemptions wholly on an in-kind basis.

Corporate Bonds Risk. Corporate bonds are typically issued by public or private companies to finance their operations and are distinct from debt securities issued by a government or its agencies. Corporate bonds may be either secured or unsecured. Corporate bonds may have more speculative characteristics in their ability to repay principal and interest than other types of fixed income securities, such as government securities. Corporate bonds contain elements of both interest-rate risk and credit risk and are subject to the risks associated with other debt securities, among other risks. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates and may also be affected by the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the marketplace. There is a risk that the issuers of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by an instrument.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Underlying Funds, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting the Fund’s third-party service providers, the Underlying Funds, and the Underlying Funds’ third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund, the Underlying Funds, or their respective advisers. Successful cyber-attacks or other cyber-failures or events affecting the Fund, the Underlying Funds or third-party service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund or the Underlying Funds invest are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyberattacks or other cyber failures.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund or an Underlying Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s or an Underlying Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the Fund’s or an Underlying Fund’s yield and may increase the risk that, if followed by rising interest rates, the Fund’s or Underlying Fund’s performance will be negatively impacted. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the Fund or an Underlying Fund, resulting in a negative impact on the Fund’s performance and NAV. Any interest rate increases could cause the value of the Fund’s or an Underlying Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the Fund or an Underlying Fund, which may force the Fund or Underlying Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

●
|
ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, there may be significantly diminished trading in Fund Shares, Fund Shares may trade at a material discount to net asset value (“NAV”), and Fund Shares may possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s
|
shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
| |
●
|
Secondary Market Trading Risk. Although Shares are intended to be listed on a national securities exchange (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. To the extent the Fund invests in Underlying Funds, which are also ETFs, the Fund will be further exposed to ETF risks.
|
| |
●
|
Cash Transactions Risk. Unlike certain ETFs, the Fund may effect its creations and redemptions partially or wholly for cash, rather than on an in-kind basis. Because of this, the Fund may incur certain costs, such as brokerage costs, or be unable to realize certain tax benefits associated with in-kind transfers of portfolio securities that may be realized by other ETFs. These costs may decrease the Fund’s NAV to the extent that the costs are not offset by a transaction fee payable by an AP. Shareholders may be subject to tax on gains they would not otherwise have been subject to and/or at an earlier date than if the Fund had effected redemptions wholly on an in-kind basis.

Tracking Error Risk. The Fund may be subject to tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the Fund, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in Fund redemption requests, including requests from shareholders who may own a significant percentage of the Fund’s Shares, which may be triggered by market turmoil or an increase in interest rates, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions. In addition, the Fund may be subject to risks associated with investments in senior non-preferred bonds (sometimes referred to as a “bail-in bonds”), which are debt securities issued by financial institutions that can be converted into equity securities if such conversion is mandated by a financial institution’s regulatory authority due to the financial institution facing the possibility of bankruptcy. The mandatory conversion of a bail-in bond into an equity security may result in a reduction in value of the security and, if the Fund holds such security when the conversion occurs, the Fund’s performance may be negatively impacted.

Actions by governments and central banking authorities can result in increases or decreases in interest rates, which may negatively affect the value of debt instruments held by the Fund and have a negative impact on the Fund’s performance and NAV. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses. During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are low and the market prices for portfolio securities have increased, the Fund may have a very low or even negative yield. A low or negative yield would cause the Fund to lose money in certain conditions and over certain time periods. An increase in interest rates will generally cause the value of securities held by Underlying Funds to decline, may lead to heightened volatility in the fixed-income markets and may adversely affect the liquidity of certain fixed-income investments, including those held by Underlying Funds. The historically low-interest rate environment in recent years heightens the risks associated with rising interest rates. Additionally, as a result of increasing interest rates, reserves held by banks and other financial institutions in bonds and other debt securities could face a significant decline in value relative to deposits and liabilities, which coupled with general economic headwinds resulting from a changing interest rate environment, creates liquidity pressures at such institutions. As a result, certain sectors of the credit markets could experience significant declines in liquidity, and it is possible that the Fund will not be able to manage this risk effectively.

Management Risk. As the Fund’s portfolio will not always replicate the Underlying Index fully, it is subject to the risk that the Adviser’s investment strategy may not produce the intended results. The Adviser’s primary use of a replication methodology, and the use of a representative sampling indexing strategy under certain circumstance, to manage the Fund’s portfolio may subject the Fund to an increased risk of tracking error, in that the Underlying Funds for the Fund’s portfolio may not have an investment profile similar to those of the Underlying Index.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investments in securities markets. Investment markets can be volatile, and prices of investments can change substantially due to various factors, including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors including economic, political, or financial events, public health crises (such as epidemics or pandemics), or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. As a result, an investor could lose money over short or long periods of time.

Tax Risk. Because the Fund is expected to invest in the Underlying Funds, distributions of short-term capital gains by an Underlying Fund will be recognized as ordinary income by the Fund and would not be offset by the Fund’s capital loss carryforwards, if any. Capital loss carryforwards of an Underlying Fund, if any, will not be available to offset net capital gains of the Fund. Further, the Fund’s realized losses on sales of shares of an Underlying Fund may be indefinitely or permanently deferred as “wash sales” to the extent it reacquires shares of the same Underlying Fund within the 61-day period beginning 30 days prior to the disposition date.

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, there may be significantly diminished trading in Fund Shares, Fund Shares may trade at a material discount to net asset value (“NAV”), and Fund Shares may possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
|
| |
●
|
Secondary Market
Trading Risk. Although Shares are intended to be listed on a national securities exchange, The Nasdaq Stock Market LLC (the “Exchange”),
and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them
will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may
be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk
is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Shares trade on a stock exchange at prices at, above, or below the Fund’s most recent NAV. The Fund’s NAV is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Shares fluctuates continuously throughout trading hours on the exchange, based on both the relative market supply of, and demand for, the Shares and the underlying value of the Fund’s portfolio holdings. As a result, the trading prices of the Shares may deviate from the Fund’s NAV. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. Any of these factors, among others, may lead to the Shares trading at a premium or discount to NAV.

Securities Lending Risk. The Fund may engage in securities lending (i.e., lend portfolio securities to institutions, such as certain broker-dealers). Securities lending involves the risk that the Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund. The Fund could also experience a loss or delay in the recovery of its securities if the borrowing institution breaches its agreement with the Fund.

Tracking Error Risk. The Fund may be subject to tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the Fund, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain RIC tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

High-Yield Securities Risk. Securities that are rated below investment-grade (commonly referred to as “junk bonds,” including those bonds rated lower than “BBB-” by S&P or “Baa3” by Moody’s), or are unrated, may be deemed speculative and may be more volatile than higher rated securities of similar maturity with respect to the issuer’s continuing ability to meet principal and interest payments. Therefore, the Fund’s investments in high-yield securities expose it to a substantial degree of credit risk. High-yield debt securities’ total return and yield may generally be expected to fluctuate more than the total return and yield of investment-grade debt securities. A real or perceived economic downturn or an increase in market interest rates could cause a decline in the value of high-yield debt securities, result in increased redemptions and/or result in increased portfolio turnover, which could result in a decline in the NAV of the Fund, reduce liquidity for certain investments and/or increase costs. High-yield debt securities are often thinly traded and can be more difficult to sell and value accurately than investment-grade debt securities because there may be no established secondary market. Investments in high-yield debt securities by Underlying Funds could increase liquidity risk for the Fund. In addition, the market for high-yield debt securities held by Underlying Funds could experience sudden and sharp volatility, which is generally associated more with investments in stocks.

The Adviser may be subject to potential conflicts of interest in selecting the Underlying Funds because affiliated Underlying Funds pay an advisory fee to the Adviser based on their assets, the fees paid to the Adviser by some affiliated Underlying Funds may be higher than other Underlying Funds or the Underlying Funds may be in need of assets to enhance their appeal to other investors, liquidity and trading and/or to enable them to carry out their investment strategies. However, the Adviser is a fiduciary to the Fund and is legally obligated to act in the Fund’s best interest when selecting Underlying Funds.

Fixed-Income Market Risk. The market value of a fixed-income security held by an Underlying Fund may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in Fund redemption requests, including requests from shareholders who may own a significant percentage of the Fund’s Shares, which may be triggered by market turmoil or an increase in interest rates, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s Share price and increase the Fund’s liquidity risk, expenses and/or taxable distributions.

Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. The Index Provider may rely on various sources of information to assess the criteria of components of the Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor the Adviser can offer assurances that the Index Provider’s methodology or sources of information will provide an accurate assessment of included components. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party provider and may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

|
Index Rebalance Risk. Pursuant to the methodology that the Index Provider uses to calculate and maintain the Underlying Index, the Fund may own a significant portion of the Underlying Funds included in the Underlying Index. Any Underlying Fund may be removed from the Underlying Index in the event that it does not comply its eligibility requirements. As a result, the Fund may be forced to sell shares of Underlying Funds at inopportune times or for prices other than at current market values or may elect not to sell such shares on the day that they are removed from the Underlying Index, due to market conditions or otherwise. Due to these factors, the variation between the Fund’s annual return and the return of the Underlying Index may increase significantly. Apart from scheduled rebalances, the Index Provider may carry out additional ad hoc rebalances to the Underlying Index to, for example, correct an error in the selection of constituents. When the Fund in turn rebalances its portfolio, any transaction costs and market exposure arising from such portfolio rebalancing will be borne by the Fund and its shareholders. Unscheduled rebalances may also expose the Fund to additional tracking error risk. Therefore, errors and additional ad hoc rebalances carried out by the Index Provider and/or the Index Calculator may increase the Fund’s costs and market exposure.

Investment in Underlying Funds Risk. The Fund’s investment in shares of Underlying Funds subjects it to the risks of owning the securities underlying the Underlying Fund, as well as the same structural risks faced by an investor purchasing shares of the Underlying Fund, including authorized participant concentration risk, market maker risk, premium/discount risk and trading issues risk. As a shareholder in an Underlying Fund, the Fund bears its proportionate share of the Underlying Fund’s expenses, subjecting Fund shareholders to duplicative expenses. Since the Fund invests in the Underlying Funds, the Fund’s investment performance and risks are likely to be directly related to those of the Underlying Funds. The Fund’s NAV will change with changes in the value of the Underlying Funds and other assets that the Fund holds. The shares of an Underlying Fund may trade at a premium or discount to the Underlying Fund’s NAV. Investors in the Fund will indirectly bear the expenses charged by the Underlying Funds, and an investment in the Fund may entail more expenses than a direct investment in the Underlying Funds.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund Shares (including through a trading halt), losses from trading in secondary markets, periods of high volatility, and disruptions in the process of creating and redeeming Fund Shares. Any of these factors, among others, may lead to the Fund’s Shares trading in the secondary market at a premium or discount to NAV or to the intraday value of the Fund’s portfolio holdings. If you buy Fund Shares at a time when the market price is at a premium to NAV or sell Fund Shares at a time when the market price is at a discount to NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund Shares.

The Fund incurs operating expenses not applicable to the Underlying Index, and may incur costs in buying and selling securities, especially when rebalancing the Fund’s portfolio holdings to reflect changes in the composition of the Underlying Index. In addition, the Fund’s portfolio holdings may not exactly replicate the securities included in the Underlying Index or the ratios between the securities included in the Underlying Index. Additionally, in order to comply with its investment strategies and policies, the Fund portfolio may deviate from the composition of the Underlying Index. Accordingly, the Fund’s return may underperform the return of the Underlying Index.

●
|
Premium/Discount Risk. The market price of the Fund’s Shares will generally fluctuate in accordance with changes in the Fund’s NAV as well as the relative supply of and demand for Shares on the exchange. The Adviser cannot predict whether Shares will trade below, at, or above their NAV because the Shares trade on the exchange at market prices and not at NAV. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for Shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that Shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAV), the Adviser believes that large discounts or premiums to the NAV of Shares should not be sustained. During stressed market conditions, the market for the Fund’s Shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying holdings, which could in turn lead to differences between the market price of the Fund’s Shares and their NAV and the bid/ask spread on the Fund’s Shares may widen.

Credit Risk. The value of your investment in the Fund may change in response to changes in the credit ratings of the Fund’s portfolio securities, including with respect to Underlying Funds. Generally, investment risk and price volatility increase as a security’s credit rating declines. The financial condition of an issuer of a fixed income security held by such Fund or an Underlying Fund may cause it to default or become unable to pay interest or principal due on the security. The value of any underlying collateral, the creditworthiness of the borrower and the priority of the lien are each of great importance. The Adviser cannot guarantee the adequacy of the protection of the Fund’s interests, including the validity or enforceability of the loan and the maintenance of the anticipated priority and perfection of the applicable security interests. Furthermore, the Adviser cannot assure that claims may not be asserted that might interfere with enforcement of the rights of the holder(s) of the relevant debt.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Fund’s investors from purchasing, redeeming or exchanging Shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks. While the Fund and the Adviser have established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Further, the Fund cannot control the cybersecurity plans and systems of the Fund’s service providers, market makers, or issuers of securities in which the Fund invests. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyberattacks or other cyber-failures.

Fixed-Income Securities Risk. Fixed-income securities are subject to the risk of the issuer’s inability to meet principal and interest payments on its obligations (i.e., credit risk) and are subject to price volatility resulting from, among other things, interest rate sensitivity, market perception of the creditworthiness of the issuer, willingness of broker-dealers and other market participants to make markets in the applicable securities, and general market liquidity (i.e., market risk). Lower rated fixed-income securities have greater volatility because there is less certainty that principal and interest payments will be made as scheduled. There is a risk that a lack of liquidity or other adverse credit market conditions may hamper the Fund’s ability to sell the debt securities in which it invests.

High Portfolio Turnover Risk. In seeking to track the Underlying Index, the Fund may incur relatively high portfolio turnover.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates, which may negatively affect the value of debt instruments held by the Fund and have a negative impact on the Fund’s performance and NAV. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses. During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are low and the market prices for portfolio securities have increased, the Fund may have a very low or even negative yield. A low or negative yield would cause the Fund to lose money in certain conditions and over certain time periods. An increase in interest rates will generally cause the value of securities held by the Fund to decline, may lead to heightened volatility in the fixed-income markets and may adversely affect the liquidity of certain fixed-income investments, including those held by the Fund. The historically low-interest rate environment in recent years heightens the risks associated with rising interest rates. Additionally, as a result of increasing interest rates, reserves held by banks and other financial institutions in bonds and other debt securities could face a significant decline in value relative to deposits and liabilities, which coupled with general economic headwinds resulting from a changing interest rate environment, creates liquidity pressures at such institutions. As a result, certain sectors of the credit markets could experience significant declines in liquidity, and it is possible that the Fund will not be able to manage this risk effectively.

Management Risk. As the Fund’s portfolio will not always replicate the Underlying Index fully, it is subject to the risk that the Adviser’s investment strategy may not produce the intended results. The Adviser’s primary use of a replication methodology, and the use of a representative sampling indexing strategy under certain circumstances, to manage the Fund’s portfolio may subject the Fund to an increased risk of tracking error, in that the securities selected in aggregate for the Fund’s portfolio may not have an investment profile similar to those of the Underlying Index.

Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. The value of the Fund and/or the Underlying Fund’s investments may be negatively affected by adverse changes in overall economic or market conditions, such as the level of economic activity and productivity, unemployment and labor force participation rates, inflation or deflation (and expectations for inflation or deflation), interest rates, demand and supply for particular products or resources including labor, and debt levels and credit ratings, among other factors. Such adverse conditions may contribute to an overall economic contraction across entire economies or markets, which may negatively impact the profitability of issuers operating in those economies or markets. The Fund and the Underlying Funds subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. The Fund and the Underlying Funds’ NAV and market price may fluctuate significantly in response to these and other factors including economic, political, or financial events, public health crises (such as epidemics or pandemics), or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. As a result, an investor could lose money over short or long periods of time.

Tax Risk. Because the Fund is expected to invest in the Underlying Funds, distributions of short-term capital gains by an Underlying Fund will be recognized as ordinary income by the Fund and would not be offset by the Fund’s capital loss carryforwards, if any. Capital loss carryforwards of an Underlying Fund, if any, will not be available to offset net capital gains of the Fund. Further, the Fund’s realized losses on sales of shares of an Underlying Fund may be indefinitely or permanently deferred as “wash sales” to the extent it reacquires shares of the same Underlying Fund within the 61-day period beginning 30 days prior to the disposition date.

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, there may be significantly diminished trading in Fund Shares, Fund Shares may trade at a material discount to net asset value (“NAV”), and Fund Shares may possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may
|
receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
| |
●
|
Secondary Market
Trading Risk. Although Shares are intended to be listed on a national securities exchange, The Nasdaq Stock Exchange LLC (the “Exchange”),
and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them
will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may
be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk
is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Shares trade on a stock exchange at prices at, above, or below the Fund’s most recent NAV. The Fund’s NAV is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Shares fluctuates continuously throughout trading hours on the exchange, based on both the relative market supply of, and demand for, the Shares and the underlying value of the Fund’s portfolio holdings. As a result, the trading prices of the Shares may deviate from the Fund’s NAV. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. Any of these factors, among others, may lead to the Shares trading at a premium or discount to NAV.

The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in Fund redemption requests, including requests from shareholders who may own a significant percentage of the Fund’s Shares, which may be triggered by market turmoil or an increase in interest rates, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s Share price and increase the Fund’s liquidity risk, expenses and/or taxable distributions.

The Index Provider may rely on various sources of information to assess the criteria of components of the Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor the Adviser can offer assurances that the Index Provider’s methodology or sources of information will provide an accurate assessment of included components. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party Provider and may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

Index Rebalance Risk. Pursuant to the methodology that the Index Provider uses to calculate and maintain the Underlying Index, the Fund may own a significant portion of the Underlying Funds included in the Underlying Index. Any Underlying Fund may be removed from the Underlying Index in the event that it does not comply its eligibility requirements. As a result, the Fund may be forced to sell shares of Underlying Funds at inopportune times or for prices other than at current market values or may elect not to sell such shares on the day that they are removed from the Underlying Index, due to market conditions or otherwise. Due to these factors, the variation between the Fund’s annual return and the return of the Underlying Index may increase significantly. Apart from scheduled rebalances, the Index Provider may carry out additional ad hoc rebalances to the Underlying Index to, for example, correct an error in the selection of constituents. When the Fund in turn rebalances its portfolio, any transaction costs and market exposure arising from such portfolio rebalancing will be borne by the Fund and its shareholders. Unscheduled rebalances may also expose the Fund to additional tracking error risk. Therefore, errors and additional ad hoc rebalances carried out by the Index Provider and/or the Index Calculator may increase the Fund’s costs and market exposure.

Investment in Underlying Funds Risk. The Fund’s investment in shares of Underlying Funds subjects it to the risks of owning the securities of the Underlying Fund, as well as the same structural risks faced by an investor purchasing shares of the Underlying Fund, including authorized participant concentration risk, market maker risk, premium/discount risk and trading issues risk. As a shareholder in another ETF, the Fund bears its proportionate share of the ETF’s expenses, subjecting Fund shareholders to duplicative expenses. Since the Fund invests in the Underlying Funds, the Fund’s investment performance and risks are likely to be directly related to those of the Underlying Funds. The Fund’s NAV will change with changes in the value of the Underlying Funds and other assets that the Fund holds. The shares of an Underlying Fund may trade at

Accordingly, the Fund’s return may underperform the return of the Underlying Index.

|
Premium/Discount Risk. The market price of the Fund’s Shares will generally fluctuate in accordance with changes in the Fund’s NAV as well as the relative supply of and demand for Shares on the exchange. The Adviser cannot predict whether Shares will trade below, at, or above their NAV because the Shares trade on the exchange at market prices and not at NAV. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for Shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that Shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAV), the Adviser believes that large discounts or premiums to the NAV of Shares should not be sustained. During stressed market conditions, the market for the Fund’s Shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying holdings, which could in turn lead to differences between the market price of the Fund’s Shares and their NAV and the bid/ask spread on the Fund’s Shares may widen.

Market Price Risk. Fund Shares are listed for trading on an exchange and are bought and sold in the secondary market at market prices. The market prices of Shares will fluctuate, in some cases materially, in response to changes in the NAV and supply and demand for Shares. As a result, the trading prices of Shares may deviate significantly from the NAV during periods of market volatility. The Adviser cannot predict whether Shares will trade above, below or at their NAV. Given the fact that Shares can be created and redeemed in Creation Units (defined below), the Adviser believes that large discounts or premiums to the NAV of Shares should not be sustained in the long-term. If market makers exit the business or are unable to continue making markets in Fund Shares, Shares may trade at a discount to NAV like closed-end fund shares and may even face delisting (that is, investors would no longer be able to trade Shares in the secondary market). Further, while the creation/redemption feature is designed to make it likely that Shares normally will trade close to the value of the Fund’s holdings, disruptions to creations and redemptions, including disruptions at market makers, APs or market participants, or during periods of significant market volatility, may result in market prices that differ significantly from the value of the Fund’s holdings. Although market makers will generally take advantage of differences between the NAV and the market price of Fund Shares through arbitrage opportunities, there is no guarantee that they will do so. In addition, the securities held by the Fund may be traded in markets that close at a different time than the exchange on which the Fund’s Shares trade. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the exchange is open but after the applicable market closing, fixing or settlement times, bid-ask spreads and the resulting premium or discount to the Shares’ NAV is likely to widen. Further, secondary markets may be subject to irregular trading activity, wide bid-ask spreads and extended trade settlement periods, which could cause a material decline in the Fund’s NAV. The Fund’s investment results are measured based upon the daily NAV of the Fund. Investors purchasing and selling Shares in the secondary market may not experience investment results consistent with those experienced by those APs creating and redeeming Shares directly with the Fund.

Pricing Risk. If market conditions make it difficult to value some investments, the Fund may value these investments using more subjective methods, such as fair value pricing. In such cases, the value determined for an investment could be different from the value realized upon such investment’s sale. As a result, you could pay more than the market value when buying Fund Shares or receive less than the market value when selling Fund Shares.

U.S. Treasury and Agency Market Risk. The U.S. Treasury and agency market can be volatile, and the value of instruments correlated with these markets may fluctuate dramatically from day to day. U.S. Treasury and agency obligations may provide relatively lower returns than those of other securities. Similar to other debt instruments, U.S. Treasury and agency obligations are subject to debt instrument risk and interest rate risk. In addition, changes to the financial condition or credit rating of the U.S. Government may cause the value of U.S. Treasury and agency obligations to decline. U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. government and are generally considered to have negligible credit risk. Securities issued or guaranteed by federal agencies or authorities and U.S. government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. government.

Credit Risk. The value of your investment in the Fund may change in response to changes in the credit ratings of the Fund’s portfolio securities, including with respect to Underlying Funds. Generally, investment risk and price volatility increase as a security’s credit rating declines. The financial condition of an issuer of a fixed income security held by such Fund or an Underlying Fund may cause it to default or become unable to pay interest or principal due on the security. The value of any underlying collateral, the creditworthiness of the borrower and the priority of the lien are each of great importance. The Adviser cannot guarantee the adequacy of the protection of the Fund’s interests, including the validity or enforceability of the loan and the maintenance of the anticipated priority and perfection of the applicable security interests. Furthermore, the Adviser cannot assure that claims may not be asserted that might interfere with enforcement of the rights of the holder(s) of the relevant debt.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Fund’s investors from purchasing, redeeming or exchanging Shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks. While the Fund and the Adviser have established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Further, the Fund cannot control the cybersecurity plans and systems of the Fund’s service providers, market makers, or issuers of securities in which the Fund invests. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyberattacks or other cyber-failures.

Fixed-Income Securities Risk. Fixed-income securities are subject to the risk of the issuer’s inability to meet principal and interest payments on its obligations (i.e., credit risk) and are subject to price volatility resulting from, among other things, interest rate sensitivity, market perception of the creditworthiness of the issuer, willingness of broker-dealers and other

market participants to make markets in the applicable securities, and general market liquidity (i.e., market risk). Lower rated fixed-income securities have greater volatility because there is less certainty that principal and interest payments will be made as scheduled.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument held by an Underlying Fund usually will not affect the amount of income the Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of an Underlying Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by an Underlying Fund’s investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates, which may negatively affect the value of debt instruments held by the Fund and have a negative impact on the Fund’s performance and NAV. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses. During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are low and the market prices for portfolio securities have increased, the Fund may have a very low or even negative yield. A low or negative yield would cause the Fund to lose money in certain conditions and over certain time periods. An increase in interest rates will generally cause the value of securities held by Underlying Funds to decline, may lead to heightened volatility in the fixed-income markets and may adversely affect the liquidity of certain fixed-income investments, including those held by Underlying Funds. The historically low-interest rate environment in recent years heightens the risks associated with rising interest rates. Additionally, as a result of increasing interest rates, reserves held by banks and other financial institutions in bonds and other debt securities could face a significant decline in value relative to deposits and liabilities, which coupled with general economic headwinds resulting from a changing interest rate environment, creates liquidity pressures at such institutions. As a result, certain sectors of the credit markets could experience significant declines in liquidity, and it is possible that the Fund will not be able to manage this risk effectively.

Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. The value of the Fund and/or an Underlying Fund’s investments may be negatively affected by adverse changes in overall economic or market conditions, such as the level of economic activity and productivity, unemployment and labor force participation rates, inflation or deflation (and expectations for inflation or deflation), interest rates, demand and supply for particular products or resources including labor, and debt levels and credit ratings, among other factors. Such adverse conditions may contribute to an overall economic contraction across entire economies or markets, which may negatively impact the profitability of issuers operating in those economies or markets. The Fund and/or an Underlying Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. The Fund and/or an Underlying Fund’s NAV and market price may fluctuate significantly in response to these and other factors including economic, political, or financial events, public health crises (such as epidemics or pandemics), or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. As a result, an investor could lose money over short or long periods of time.

Further, the Fund’s realized losses on sales of shares of an Underlying Fund may be indefinitely or permanently deferred as “wash sales” to the extent it reacquires shares of the same Underlying Fund within the 61-day period beginning 30 days prior to the disposition date.

|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, there may be significantly diminished trading in Fund Shares, Fund Shares may trade at a material discount to net asset value (“NAV”), and Fund Shares may possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.

Secondary Market
Trading Risk. Although Shares are intended to be listed on a national securities exchange, The Nasdaq Stock Market LLC (the “Exchange”),
and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them
will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may
be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk
is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Shares trade on a stock exchange at prices at, above, or below the Fund’s most recent NAV. The Fund’s NAV is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Shares fluctuates continuously throughout trading hours on the exchange, based on both the relative market supply of, and demand for, the Shares and the underlying value of the Fund’s portfolio holdings. As a result, the trading prices of the Shares may deviate from the Fund’s NAV. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. Any of these factors, among others, may lead to the Shares trading at a premium or discount to NAV.

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in Fund redemption requests, including requests from shareholders who may own a significant percentage of the Fund’s Shares, which may be triggered by market turmoil or an increase in interest rates, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s Share price and increase the Fund’s liquidity risk, expenses and/or taxable distributions.

Reverse repurchase agreements involve the risk that the investment return earned by the Fund (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Fund will decline below the price the Fund is obligated to pay to repurchase the securities, and that the other party may fail to return the securities in a timely manner or at all.

Rating Agencies Risk. Ratings are not an absolute standard of quality, but rather general indicators that reflect only the view of the originating rating agencies from which an explanation of the significance of such ratings may be obtained. There is no assurance that a particular rating will continue for any given period of time or that any such rating will not be revised downward or withdrawn entirely if, in the judgment of the agency establishing the rating, circumstances so warrant. A downward revision or withdrawal of such ratings, or either of them, may have an effect on the liquidity or market price of the securities in which an Underlying Fund invests.

When a substantial portion of a portfolio is held in cash or cash equivalents, there is the risk that the value of the cash account, including interest, will not keep pace with inflation, thus reducing purchasing power over time. Additionally, in rising markets, holding cash or cash equivalents may adversely affect the Fund’s performance and the Fund may not achieve its investment objectives.

|
Index Rebalance Risk. Pursuant to the methodology that the Index Provider uses to calculate and maintain the Underlying Index, the Fund may own a significant portion of the Underlying Funds included in the Underlying Index. Any Underlying Fund may be removed from the Underlying Index in the event that it does not comply its eligibility requirements. As a result, the Fund may be forced to sell shares of Underlying Funds at inopportune times or for prices other than at current market values or may elect not to sell such shares on the day that they are removed from the Underlying Index, due to market conditions or otherwise. Due to these factors, the variation between the Fund’s annual return and the return of the Underlying Index may increase significantly. Apart from scheduled rebalances, the Index Provider may carry out additional ad hoc rebalances to the Underlying Index to, for example, correct an error in the selection of constituents. When the Fund in turn rebalances its portfolio, any transaction costs and market exposure arising from such portfolio rebalancing will be borne by the Fund and its shareholders. Unscheduled rebalances may also expose the Fund to additional tracking error risk. Therefore, errors and additional ad hoc rebalances carried out by the Index Provider and/or the Index Calculator may increase the Fund’s costs and market exposure.

Investment in Underlying Funds Risk. The Fund’s investment in shares of Underlying Funds subjects it to the risks of owning the securities of the Underlying Fund, as well as the same structural risks faced by an investor purchasing shares of the Underlying Fund, including authorized participant concentration risk, market maker risk, premium/discount risk and trading issues risk. As a shareholder in another ETF, the Fund bears its proportionate share of the ETF’s expenses, subjecting Fund shareholders to duplicative expenses. Since the Fund invests in the Underlying Funds, the Fund’s investment performance and risks are likely to be directly related to those of the Underlying Funds. The Fund’s NAV will change with changes in the value of the Underlying Funds and other assets that the Fund holds. The shares of an Underlying Fund may trade at a premium or discount to the Underlying Fund’s NAV. Investors in the Fund will indirectly bear the expenses charged by the Underlying Funds, and an investment in the Fund may entail more expenses than a direct investment in the Underlying Funds.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund Shares (including through a trading halt), losses from trading in secondary markets, periods of high volatility, and disruptions in the process of creating and redeeming Fund Shares. Any of these factors, among others, may lead to the Fund’s Shares trading in the secondary market at a premium or discount to NAV or to the intraday value of the Fund’s portfolio holdings. If you buy Fund Shares at a time when the market price is at a premium to NAV or sell Fund Shares at a time when the market price is at a discount to NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund Shares.

Non-Correlation Risk. The Fund’s return may not match the return of the Underlying Index for a number of reasons. The Fund incurs operating expenses not applicable to the Underlying Index, and may incur costs in buying and selling securities, especially when rebalancing the Fund’s portfolio holdings to reflect changes in the composition of the Underlying Index. In addition, the Fund’s portfolio holdings may not exactly replicate the securities included in the Underlying Index or the ratios between the securities included in the Underlying Index. Additionally, in order to comply with its investment strategies and policies, the Fund portfolio may deviate from the composition of the Underlying Index. Accordingly, the Fund’s return may underperform the return of the Underlying Index.

|
Premium/Discount Risk. The market price of the Fund’s Shares will generally fluctuate in accordance with changes in the Fund’s NAV as well as the relative supply of and demand for Shares on the exchange. The Adviser cannot predict whether Shares will trade below, at, or above their NAV because the Shares trade on the exchange at market prices and not at NAV. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for Shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that Shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAV), the Adviser believes that large discounts or premiums to the NAV of Shares should not be sustained. During stressed market conditions, the market for the Fund’s Shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying holdings, which could in turn lead to differences between the market price of the Fund’s Shares and their NAV and the bid/ask spread on the Fund’s Shares may widen.

Market Price Risk. Fund Shares are listed for trading on an exchange and are bought and sold in the secondary market at market prices. The market prices of Shares will fluctuate, in some cases materially, in response to changes in the NAV and supply and demand for Shares. As a result, the trading prices of Shares may deviate significantly from the NAV during periods of market volatility. The Adviser cannot predict whether Shares will trade above, below or at their NAV. Given the fact that Shares can be created and redeemed in Creation Units (defined below), the Adviser believes that large discounts or premiums to the NAV of Shares should not be sustained in the long-term. If market makers exit the business or are unable to continue making markets in Fund Shares, Shares may trade at a discount to NAV like closed-end fund shares and may even face delisting (that is, investors would no longer be able to trade Shares in the secondary market). Further, while the creation/redemption feature is designed to make it likely that Shares normally will trade close to the value of the Fund’s holdings, disruptions to creations and redemptions, including disruptions at market makers, APs or market participants, or during periods of significant market volatility, may result in market prices that differ significantly from the value of the Fund’s holdings. Although market makers will generally take advantage of differences between the NAV and the market price of Fund Shares through arbitrage opportunities, there is no guarantee that they will do so. In addition, the securities held by the Fund may be traded in markets that close at a different time than the exchange on which the Fund’s Shares trade. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the exchange is open but after the applicable market closing, fixing or settlement times, bid-ask spreads and the resulting premium or discount to the Shares’ NAV is likely to widen. Further, secondary markets may be subject to irregular trading activity, wide bid-ask spreads and extended trade settlement periods, which could cause a material decline in the Fund’s NAV. The Fund’s investment results are measured based upon the daily NAV of the Fund. Investors purchasing and selling Shares in the secondary market may not experience investment results consistent with those experienced by those APs creating and redeeming Shares directly with the Fund.

Mortgage-Backed and Asset-Backed Securities Risk. The Fund may invest in Underlying Funds that invest in mortgage- and asset-backed securities, which are subject to call (prepayment) risk, reinvestment risk and extension risk. In addition, these securities are susceptible to an unexpectedly high rate of defaults on the mortgages held by a mortgage pool, which may adversely affect their value. The risk of such defaults depends on the quality of the mortgages underlying such security, the credit quality of its issuer or guarantor, and the nature and structure of its credit support. For example, the risk of default generally is higher in the case of mortgage pools that include subprime mortgages, which are loans made to borrowers with weakened credit histories or with lower capacity to make timely mortgage payments.

Prepayment and Extension Risk. When interest rates fall, issuers of high interest debt obligations may pay off the debts earlier than expected (prepayment risk), and the Fund may have to reinvest the proceeds at lower yields. When interest rates rise, issuers of lower interest debt obligations may pay off the debts later than expected (extension risk), thus keeping the Fund’s assets tied up in lower interest debt obligations. Ultimately, any unexpected behavior in interest rates could increase the volatility of the Fund’s Share price and yield and could hurt fund performance. Prepayments could also create capital gains tax liability in some instances.

When-Issued Securities Risk. The Fund may invest in Underlying Funds that purchase securities on a when-issued or forward commitment basis. The purchase price of such securities is typically fixed at the time of the commitment, with delivery and payment taking place in the future. At the time of delivery of the securities, the value may be more or less than the purchase or sale price. Purchase of securities on a when-issued or forward commitment basis may give rise to investment leverage, and may result in increased volatility of the Underlying Fund’s NAV. Default by, or bankruptcy of, a counterparty to a when-issued transaction would expose the Underlying Fund to possible losses because of an adverse market action, expenses or delays in connection with the purchase or sale of the pools specified in such transaction. The Financial Industry Regulatory Authority, Inc. (“FINRA”) Rules impose mandatory margin requirements for certain types of when-issued or forward commitment transactions, with limited exceptions. Such transactions require mandatory collateralization, which may increase the cost of such transactions and impose added operational complexity.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. While the Fund and the Adviser have established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Further, the Fund cannot control the cybersecurity plans and systems of the Fund’s service providers, market makers, or issuers of securities in which the Fund invests. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyberattacks or other cyber-failures.

Fixed-Income Securities Risk. Fixed-income securities are subject to the risk of the issuer’s inability to meet principal and interest payments on its obligations (i.e., credit risk) and are subject to price volatility resulting from, among other things, interest rate sensitivity, market perception of the creditworthiness of the issuer, willingness of broker-dealers and other market participants to make markets in the applicable securities, and general market liquidity (i.e., market risk). Lower rated fixed-income securities have greater volatility because there is less certainty that principal and interest payments will be made as scheduled. There is a risk that a lack of liquidity or other adverse credit market conditions may hamper the Fund’s ability to sell the debt securities in which it invests.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates, which may negatively affect the value of debt instruments held by the Fund and have a negative impact on the Fund’s performance and NAV. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses. During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are low and the market prices for portfolio securities have increased, the Fund may have a very low or even negative yield. A low or negative yield would cause the Fund to lose money in certain conditions and over certain time periods. An increase in interest rates will generally cause the value of securities held by the Fund to decline, may lead to heightened volatility in the fixed-income markets and may adversely affect the liquidity of certain fixed-income investments, including those held by the Fund. Additionally, as a result of increasing interest rates, reserves held by banks and other financial institutions in bonds and other debt securities could face a significant decline in value relative to deposits and liabilities, which coupled with general economic headwinds resulting from a changing interest rate environment, creates liquidity pressures at such institutions. As a result, certain sectors of the credit markets could experience significant declines in liquidity, and it is possible that the Fund will not be able to manage this risk effectively.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investments in securities markets. Investment markets can be volatile, and prices of investments can change substantially due to various factors, including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors including economic, political, or financial events, public health crises (such as epidemics or pandemics), or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. As a result, an investor could lose money over short or long periods of time.

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, there may be significantly diminished trading in Fund Shares, Fund Shares may trade at a material discount to net asset value (“NAV”), and Fund Shares may possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
|
| |
●
|
Secondary
Market Trading Risk. Although Shares are listed on a national securities exchange, The Nasdaq Stock Market, LLC (the
“Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or
liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During
periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than
the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Shares trade on a stock exchange at prices at, above, or below the Fund’s most recent NAV. The Fund’s NAV is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Shares fluctuates continuously throughout trading hours on the exchange, based on both the relative market supply of, and demand for, the Shares and the underlying value of the Fund’s portfolio holdings. As a result, the trading prices of the Shares may deviate from the Fund’s NAV. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. Any of these factors, among others, may lead to the Shares trading at a premium or discount to NAV.

Illiquid Investments Risk. The Fund may not acquire any illiquid investment if, immediately after the acquisition, the Fund will have invested more than 15% of its net assets in illiquid investments. An illiquid investment is any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without significantly changing the market value of the investment. To the extent the Fund holds illiquid investments, the illiquid investments may reduce the returns of the Fund because the Fund may be unable to transact at advantageous times or prices. In addition, if the Fund is limited in its ability to sell illiquid investments during periods when shareholders are redeeming their Shares, the Fund will need to sell liquid securities to meet redemption requests and illiquid securities will become a larger portion of the Fund’s holdings. During periods of market volatility, liquidity in the market for the Fund’s Shares may be impacted by the liquidity in the market for the underlying securities or instruments held by the Fund, which could lead to the Fund’s Shares trading at a premium or discount to NAV.

Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the Fund, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

High Yield Securities Risk. Securities that are rated below investment-grade (commonly referred to as “junk bonds,” including those bonds rated lower than “BBB-” by S&P or “Baa3” by Moody’s), or are unrated, may be deemed speculative and may be more volatile than higher rated securities of similar maturity with respect to the issuer’s continuing ability to meet principal and interest payments. High-yield debt securities’ total return and yield may generally be expected to fluctuate more than the total return and yield of investment-grade debt securities. A real or perceived economic downturn or an increase in market interest rates could cause a decline in the value of high-yield debt securities, result in increased redemptions and/or result in increased portfolio turnover, which could result in a decline in the NAV of the Fund, reduce liquidity for certain investments and/or increase costs. High-yield debt securities are often thinly traded and can be more difficult to sell and value accurately than investment-grade debt securities because there may be no established secondary market. Investments in high-yield debt securities could increase liquidity risk for the Fund. In addition, the market for high-yield debt securities could experience sudden and sharp volatility, which is generally associated more with investments in stocks.

Affiliated Fund Risk. Affiliated fund risk is the risk that the Adviser may select investments for the Fund based on its own financial interests or other business considerations rather than the Fund’s interests. The Adviser may be subject to potential conflicts of interest in selecting the Underlying Funds because the Underlying Funds pay an advisory fee to the Adviser based on their assets, the fees paid to the Adviser by some affiliated Underlying Funds may be higher than other Underlying Funds or the Underlying Funds may be in need of assets to enhance their appeal to other investors, liquidity and trading and/or to enable them to carry out their investment strategies. However, the Adviser is a fiduciary to the Fund and is legally obligated to act in the Fund’s best interest when selecting Underlying Funds.

Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer- duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities. As interest rates rise, the value of a bond will fall in direct proportion to its duration and conversely, as interest rates fall, the value of a bond will increase in direct proportion to its duration. Therefore, the longer a bond’s duration (measured in years), the more sensitive its price will be to interest rate changes.

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in Fund redemption requests, including requests from shareholders who may own a significant percentage of the Fund’s Shares, which may be triggered by market turmoil or an increase in interest rates, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s Share price and increase the Fund’s liquidity risk, expenses and/or taxable distributions.

There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. The Index Provider may rely on various sources of information to assess the criteria of components of the Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor the Adviser can offer assurances that the Index Provider’s methodology or sources of information will provide an accurate assessment of included components. Errors in index data, index computations or the construction of the Underlying Index in

accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party Provider and may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

Also, current military conflicts in various geographic regions, including those in Europe and the Middle East, can lead to, and have led to, economic and market disruptions, which may not be limited to the geographic region in which the conflict is occurring. Such conflicts can also result, and have resulted in some cases, in sanctions being levied by the United States, the European Union and/or other countries against countries or other actors involved in the conflict. In addition, such conflicts and related sanctions can adversely affect regional and global energy, commodities, financial and other markets and thus could affect the value of the Fund’s investments. The extent and duration of any military conflict, related sanctions and resulting economic and market disruptions are impossible to predict, but could be substantial.

Inflation, and investors’ expectation of future inflation, can impact the current value of the Fund’s portfolio, resulting in lower asset values and losses to shareholders. This risk may be elevated compared to historical market conditions because of recent monetary policy measures and the current interest rate environment.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares (including through a trading halt), losses from trading in secondary markets, periods of high volatility, and disruptions in the process of creating and redeeming Fund shares. Any of these factors, among others, may lead to the Fund’s shares trading in the secondary market at a premium or discount to NAV or to the intraday value of the Fund’s portfolio holdings. If you buy Fund shares at a time when the market price is at a premium to NAV or sell Fund shares at a time when the market price is at a discount to NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund Shares.

|
Market Price Risk. Fund shares are listed for trading on an exchange and are bought and sold in the secondary market at market prices. The market prices of shares will fluctuate, in some cases materially, in response to changes in the NAV and supply and demand for shares. As a result, the trading prices of shares may deviate significantly from the NAV during periods of market volatility. The Adviser cannot predict whether shares will trade above, below or at their NAV. Given the fact that shares can be created and redeemed in Creation Units (defined below), the Adviser believes that large discounts or premiums to the NAV of shares should not be sustained in the long-term. If market makers exit the business or are unable to continue making markets in Fund shares, shares may trade at a discount to NAV like closed-end fund shares and may even face delisting (that is, investors would no longer be able to trade shares in the secondary market). Further, while the creation/redemption feature is designed to make it likely that Shares normally will trade close to the value of the Fund’s holdings, disruptions to creations and redemptions, including disruptions at market makers, APs or market participants, or during periods of significant market volatility, may result in market prices that differ significantly from the value of the Fund’s holdings. Although market makers will generally take advantage of differences between the NAV and the market price of Fund Shares through arbitrage opportunities, there is no guarantee that they will do so. In addition, the securities held by the Fund may be traded in markets that close at a different time than the exchange on which the Fund’s Shares trade. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the exchange is open but after the applicable market closing, fixing or settlement times, bid-ask spreads and the resulting premium or discount to the Shares’ NAV is likely to widen. Further, secondary markets may be subject to irregular trading activity, wide bid-ask spreads and extended trade settlement periods, which could cause a material decline in the Fund’s NAV. The Fund’s investment results are measured based upon the daily NAV of the Fund. Investors purchasing and selling Shares in the secondary market may not experience investment results consistent with those experienced by those APs creating and redeeming shares directly with the Fund.

Prepayment and Extension Risk. When interest rates fall, issuers of high interest debt obligations may pay off the debts earlier than expected (prepayment risk), and the Fund may have to reinvest the proceeds at lower yields. When interest rates rise, issuers of lower interest debt obligations may pay off the debts later than expected (extension risk), thus keeping the Fund’s assets tied up in lower interest debt obligations. Ultimately, any unexpected behavior in interest rates could increase the volatility of the Fund’s share price and yield and could hurt fund performance. Prepayments could also create capital gains tax liability in some instances.

These risks include greater market volatility, less market liquidity, higher transaction costs, expropriation, confiscatory taxation, adverse changes in foreign investment or currency control regulations, restrictions on the repatriation of capital, and political instability. Non-U.S. issuers may be subject to different accounting, audit and financial reporting standards than U.S. issuers, and there may be less publicly available information about non-U.S. issuers. Foreign governments may restrict investment by foreigners, limit withdrawal of trading profit or currency from the country, restrict currency exchange or seize foreign investments. In addition, the Fund may be limited in its ability to exercise its legal rights or enforce a counterparty’s legal obligations in certain jurisdictions outside of the U.S. Foreign market trading hours, different clearing and settlement procedures, and holiday schedules may limit the Fund’s ability to engage in portfolio transactions.

Restricted Securities/Rule 144A Securities Risk. The Fund may invest in securities offered pursuant to Rule 144A under the Securities Act of 1933, as amended (the “1933 Act”), which are restricted securities. They may be less liquid and more difficult to value than other investments because such securities may not be readily marketable in broad public markets. The Fund may not be able to sell a restricted security promptly or at a reasonable price. Although there is a substantial institutional market for Rule 144A securities, it is not possible to predict exactly how the market for Rule 144A securities will develop. A restricted security that was liquid at the time of purchase may subsequently become illiquid and its value may decline as a result. Restricted securities that are deemed illiquid will count towards the Fund’s 15% limitation on illiquid securities. In addition, transaction costs may be higher for restricted securities than for more liquid securities. The Fund may have to bear the expense of registering Rule 144A securities for resale and the risk of substantial delays in effecting the registration.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. While the Fund and the Adviser have established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Further, the Fund cannot control the cybersecurity plans and systems of the Fund’s service providers, market makers, or issuers of securities in which the Fund invests. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates, which may negatively affect the value of debt instruments held by the Fund and have a negative impact on the Fund’s performance and NAV. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses. During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are low and the market prices for portfolio securities have increased, the Fund may have a very low or even negative yield. A low or negative yield would cause the Fund to lose money in certain conditions and over certain time periods. An increase in interest rates will generally cause the value of securities held by the Fund to decline, may lead to heightened volatility in the fixed-income markets and may adversely affect the liquidity of certain fixed-income investments, including those held by the Fund. Additionally, as a result of increasing interest rates, reserves held by banks and other financial institutions in bonds and other debt securities could face a significant decline in value relative to deposits and liabilities, which coupled with general economic headwinds resulting from a changing interest rate environment, creates liquidity pressures at such institutions. As a result, certain sectors of the credit markets could experience significant declines in liquidity, and it is possible that the Fund will not be able to manage this risk effectively.

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, there may be significantly diminished trading in Shares, Fund Shares may trade at a material discount to net asset value (“NAV”),
|
and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
| |
●
|
Secondary Market Trading Risk. Although Shares are intended to be listed on The Nasdaq Stock Market LLC, a national securities exchange, (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Shares trade on a stock exchange at prices at, above, or below the Fund’s most recent NAV. The Fund’s NAV is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Shares fluctuates continuously throughout trading hours on the exchange, based on both the relative market supply of, and demand for, the Shares and the underlying value of the Fund’s portfolio holdings. As a result, the trading prices of the Shares may deviate from the Fund’s NAV. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. Any of these factors, among others, may lead to the Shares trading at a premium or discount to NAV.

Securities Lending Risk. The Fund may engage in securities lending (i.e., lend portfolio securities to institutions, such as certain broker dealers). Securities lending involves the risk that the Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund. The Fund could also experience a loss or delay in the recovery of its securities if the borrowing institution breaches its agreement with the Fund.

Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities. As interest rates rise, the value of a bond will fall in direct proportion to its duration and conversely, as interest rates fall, the value of a bond will increase in direct proportion to its duration. Therefore, the longer a bond’s duration (measured in years), the more sensitive its price will be to interest rate changes.

|
Fixed Income Market Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities or duration will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. The Index Provider may rely on various sources of information to assess the criteria of components of the Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor the Adviser can offer assurances that the Index Provider’s methodology or sources of information will provide an accurate assessment of included components. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party provider and may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s portfolio holdings, which may cause a variance in the market price of Shares and their underlying NAV. In addition, an exchange or market may issue trading halts on specific securities or financial instruments. As a result, the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation/redemption process, potentially affect the price at which Shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments at all. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV.

|
Market Price Risk. Fund Shares are listed for trading on an exchange and are bought and sold in the secondary market at market prices. The market prices of Shares will fluctuate, in some cases materially, in response to changes in the NAV and supply and demand for Shares. As a result, the trading prices of Shares may deviate significantly from the NAV during periods of market volatility. The Adviser cannot predict whether Shares will trade above, below or at their NAV. Given the fact that Shares can be created and redeemed in Creation Units (defined below), the Adviser believes that large discounts or premiums to the NAV of Shares should not be sustained in the long-term. If market makers exit the business or are unable to continue making markets in Fund Shares, Shares may trade at a discount to NAV like closed-end fund shares and may even face delisting (that is, investors would no longer be able to trade Shares in the secondary market). Further, while the creation/redemption feature is designed to make it likely that Shares normally will trade close to the value of the Fund’s holdings, disruptions to creations and redemptions, including disruptions at market makers, APs or market participants, or during periods of significant market volatility, may result in market prices that differ significantly from the value of the Fund’s holdings. Although market makers will generally take advantage of differences between the NAV and the market price of Fund Shares through arbitrage opportunities, there is no guarantee that they will do so. In addition, the securities held by the Fund may be traded in markets that close at a different time than the exchange on which the Fund’s Shares trade. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the exchange is open but after the applicable market closing, fixing or settlement times, bid-ask spreads and the resulting premium or discount to the Shares’ NAV is likely to widen. Further, secondary markets may be subject to irregular trading activity, wide bid-ask spreads and extended trade settlement periods, which could cause a material decline in the Fund’s NAV. The Fund’s investment results are measured based upon the daily NAV of the Fund. Investors purchasing and selling Shares in the secondary market may not experience investment results consistent with those experienced by those APs creating and redeeming Shares directly with the Fund.

|
Inflation-Indexed Bonds Risk. The principal value of an investment is not protected or otherwise guaranteed by virtue of the Fund’s investments in inflation-indexed bonds. Inflation-indexed bonds are fixed-income securities whose principal value is periodically adjusted according to the rate of inflation. If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds. For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal value. The value of inflation-indexed bonds is expected to change in response to changes in real interest rates. Real interest rates are tied to the relationship between nominal interest rates and the rate of inflation. If nominal interest rates increase at a faster rate than inflation, real interest rates may rise, leading to a decrease in value of inflation-indexed bonds. Short-term increases in inflation may lead to a decline in value. Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even though investors do not receive their principal until maturity. Periodic adjustments for inflation to the principal amount of an inflation-indexed bond may give rise to original issue discount, which will be includable in the Fund’s gross income. Due to original issue discount, the Fund may be required to make annual distributions to shareholders that exceed the cash received, which may cause the Fund to liquidate certain investments when it is not advantageous to do so. Also, if the principal value of an inflation-indexed bond is adjusted downward due to deflation, amounts previously distributed in the taxable year may be characterized in some circumstances as a return of capital.

|
Inflation-Linked Securities Risk. In general, the value of an inflation-linked security, including TIPS, will typically decrease when real interest rates (nominal interest rates reduced by the expected impact of inflation) increase and increase when real interest rates decrease. When inflation is negative or concerns over inflation are low, the value and income of inflationlinked securities could fall and result in losses for the Fund and during periods of very low inflation, the yield on an inflation-linked security may be negative. Conversely, during sustained periods of high inflation, the Fund’s yield should increase, which may not be repeated. Funds that invest heavily in inflation-linked securities do not always move in lockstep with inflation because they do not necessarily buy inflation-linked securities when they are originally issued or hold them until maturity. In addition, the accrual of inflation adjustments on the Fund’s holdings may significantly impact the current level of dividends actually paid to shareholders. Changes in inflation rates and/or interest rates may cause the Fund’s yield to vary substantially over time.

U.S. Treasury Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund’s U.S. Treasury obligations to decline.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. While the Fund and the Adviser have established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems.
|
Further, the Fund cannot control the cybersecurity plans and systems of the Fund’s Index Provider and other service providers, market makers, or issuers of securities in which the Fund invests. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyberattacks or other cyber-failures.

For example, the economies of such countries can be subject to rapid and unpredictable rates of inflation or deflation. Low trading volumes may result in a lack of liquidity and price volatility. Emerging market countries may have policies that restrict investment by non-U.S. investors, or that prevent non-U.S. investors from withdrawing their money at will. The Fund may invest in some emerging markets that subject it to risks such as those associated with illiquidity, custody of assets, different settlement and clearance procedures and asserting legal title under a developing legal and regulatory regime to a greater degree than in developed markets or even in other emerging markets.

|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, there may be significantly diminished trading in Fund Shares, Fund Shares may trade at a material discount to net asset value (“NAV”), and Fund Shares may possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
|
| |
●
|
Secondary Market Trading Risk. Although Shares are intended to be listed on a national securities exchange (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Shares trade on a stock exchange at prices at, above, or below the Fund’s most recent NAV. The Fund’s NAV is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Shares fluctuates continuously throughout trading hours on the exchange, based on both the relative market supply of, and demand for, the Shares and the underlying value of the Fund’s portfolio holdings. As a result, the trading prices of the Shares may deviate from the Fund’s NAV. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. Any of these factors, among others, may lead to the Shares trading at a premium or discount to NAV.

Geographic Risk. A natural disaster could occur in a geographic region in which the Fund invests, which could adversely affect the economy or the business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in, or which are exposed to, the affected region. Also, current military conflicts in various geographic regions, including those in Europe and the Middle East, can lead to, and have led to, economic and market disruptions, which may not be limited to the geographic region in which the conflict is occurring. Such conflicts can also result, and have resulted in some cases, in sanctions being levied by the United States, the European Union and/or other countries against countries or other actors involved in the conflict. In addition, such conflicts and related sanctions can adversely affect regional and global energy, commodities, financial and other markets and thus could affect the value of the Fund’s investments. The extent and duration of any military conflict, related sanctions and resulting economic and market disruptions are impossible to predict, but could be substantial.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares (including through a trading halt), losses from trading in secondary markets, periods of high volatility, and disruptions in the process of creating and redeeming Fund shares. Any of these factors, among others, may lead to the Fund’s shares trading in the secondary market at a premium or discount to NAV or to the intraday value of the Fund’s portfolio holdings. If you buy Fund shares at a time when the market price is at a premium to NAV or sell Fund shares at a time when the market price is at a discount to NAV, you may pay significantly more or receive significantly less than the underlying value of the Fund Shares.

Depository Receipts Risk. The Fund may hold the securities of non-U.S. companies in the form of American Depositary Receipts (“ADRs”). ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Foreign Investment Risk. The Fund faces the risks inherent in foreign investing. Adverse political, economic or social developments could undermine the value of the Fund’s foreign investments, prevent the Fund from realizing the full value of its foreign investments or prevent the Fund from selling foreign securities it holds. Financial reporting standards for companies based in foreign markets differ from those in the United States. Additionally, foreign securities markets generally are smaller and less liquid than U.S. markets. Foreign governments may restrict investment by foreigners, limit withdrawal of trading profit or currency from the country, restrict currency exchange or seize foreign investments. In addition, the Fund may be limited in its ability to exercise its legal rights or enforce a counterparty’s legal obligations in certain jurisdictions outside of the U.S. The foreign investments of the Fund may also be subject to foreign withholding taxes. Foreign brokerage commissions and other fees are generally higher than those for U.S. investments, and the transactions and custody of foreign assets may involve delays in payment, delivery or recovery of money or investments. Foreign markets can have liquidity risks beyond those typical of U.S. markets. Because foreign exchanges generally are smaller and less liquid than U.S. exchanges, buying and selling foreign investments can be more difficult and costly. Relatively small transactions can sometimes materially affect the price and availability of securities. In certain situations, it may become virtually impossible to sell an investment at a price that approaches portfolio management’s estimate of its value. For the same reason, it may at times be difficult to value the Fund’s foreign investments. In addition, because non-U.S. markets may be open on days when the Fund does not price its shares, the value of the foreign securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s Shares.

Initial Public Offering (“IPO”) Risk. The Fund may invest in companies that have recently completed an initial public offering. The stocks of such companies are unseasoned equities lacking a trading history, a track record of reporting to investors and widely available research coverage. IPOs are thus often subject to extreme price volatility and speculative trading. In addition, IPOs share similar illiquidity risks of private equity and venture capital. The free float shares held by the public in an IPO are typically a small percentage of the market capitalization. The ownership of many IPOs often includes large holdings by venture capital and private equity investors who seek to sell their shares in the public market in the months following an IPO when shares restricted by lock-up are released, causing greater volatility and possible downward pressure during the time that locked-up shares are released.

Real Estate Investment Trust (“REIT”) Risk. REITs are subject to the risks associated with investing in the securities of real property companies. In particular, REITs may be affected by changes in the values of the underlying properties that they own or operate. Further, REITs are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs are also subject to heavy cash flow dependency and, as a result, are particularly reliant on the proper functioning of capital markets. A variety of economic and other factors may adversely affect a lessee’s ability to meet its obligations to a REIT. In the event of a default by a lessee, the REIT may experience delays in enforcing its rights as a lessor and may incur substantial costs associated in protecting its investments. In addition, a REIT could fail to qualify for favorable regulatory treatment.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer
|
data breaches, data corruption or lose operational functionality or prevent the Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. While the Fund and the Adviser have established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Further, the Fund cannot control the cybersecurity plans and systems of the Fund’s Index Provider and other service providers, market makers, or issuers of securities in which the Fund invests. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyberattacks or other cyber-failures.

Emerging Markets Risk. The risks of foreign investments are greater for investments in or exposed to emerging markets. Emerging market countries typically have economic and political systems that are less fully developed, and can be expected to be less stable, than those of more developed countries. For example, the economies of such countries can be subject to rapid and unpredictable rates of inflation or deflation. Low trading volumes may result in a lack of liquidity and price volatility. Emerging market countries may have policies that restrict investment by non-U.S. investors, or that prevent non-U.S. investors from withdrawing their money at will. The Fund may invest in some emerging markets that subject it to risks such as those associated with illiquidity, custody of assets, different settlement and clearance procedures and asserting legal title under a developing legal and regulatory regime to a greater degree than in developed markets or even in other emerging markets.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investments in securities markets. Investment markets can be volatile, and prices of investments can change substantially due to various factors, including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors including economic, political, or financial events, public health crises (such as epidemics or pandemics), or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. As a result, an investor could lose money over short or long periods of time.

Economic, political, and financial conditions, or industry or economic trends or developments, may for varying periods of time cause volatility, illiquidity, or other potentially adverse effects in the markets.

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, there may be significantly diminished trading in Fund Shares, Fund Shares may trade at a material discount to net asset value (“NAV”), and Fund Shares may possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
|
| |
●
|
Secondary Market Trading Risk. Although Shares are intended to be listed on a national securities exchange (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During
|
periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Shares trade on a stock exchange at prices at, above, or below the Fund’s most recent NAV. The Fund’s NAV is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Shares fluctuates continuously throughout trading hours on the exchange, based on both the relative market supply of, and demand for, the Shares and the underlying value of the Fund’s portfolio holdings. As a result, the trading prices of the Shares may deviate from the Fund’s NAV. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. Any of these factors, among others, may lead to the Shares trading at a premium or discount to NAV.

The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund. The Fund could also experience a loss or delay in the recovery of its securities if the borrowing institution breaches its agreement with the Fund.

Emerging market countries may have policies that restrict investment by non-U.S. investors, or that prevent non-U.S. investors from withdrawing their money at will. The Fund may invest in some emerging markets that subject it to risks such as those associated with illiquidity, custody of assets, different settlement and clearance procedures and asserting legal title under a developing legal and regulatory regime to a greater degree than in developed markets or even in other emerging markets.

Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investments in securities markets. Investment markets can be volatile, and prices of investments can change substantially due to various factors, including, but not limited to, economic growth or recession, changes in interest rates,
|
inflation, changes in the actual or perceived creditworthiness of issuers and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors including economic, political, or financial events, public health crises (such as epidemics or pandemics), or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. As a result, an investor could lose money over short or long periods of time.

Equity Securities Risk. The price of equity securities fluctuates based on changes in a company’s activities and financial condition and in overall market conditions. Economic, political, and financial conditions, or industry or economic trends or developments, may for varying periods of time cause volatility, illiquidity, or other potentially adverse effects in the markets. The Fund’s investments in equity securities expose it to sudden and unpredictable drops in value and the potential for extended periods of lackluster performance.

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, there may be significantly diminished trading in Fund Shares, Fund Shares may trade at a material discount to net asset value (“NAV”), and Fund Shares may possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
|
| |
●
|
Secondary Market Trading Risk. Although Shares are intended to be listed on a national securities exchange (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Shares trade on a stock exchange at prices at, above, or below the Fund’s most recent NAV. The Fund’s NAV is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Shares fluctuates continuously throughout trading hours on the exchange, based on both the relative market supply of, and demand for, the Shares and the underlying value of the Fund’s portfolio holdings. As a result, the trading prices of the Shares may deviate from the Fund’s NAV. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. Any of these factors, among others, may lead to the Shares trading at a premium or discount to NAV.

Also, current military conflicts in various geographic regions, including those in Europe and the Middle East, can lead to, and have led to, economic and market disruptions, which may not be limited to the geographic region in which the conflict is occurring. Such conflicts can also result, and have resulted in some cases, in sanctions being levied by the United States, the European Union and/or other countries against countries or other actors involved in the conflict. In addition, such conflicts and related sanctions can adversely affect regional and global energy, commodities, financial and other markets and thus could affect the value of the Fund’s investments. The extent and duration of any military conflict, related sanctions and resulting economic and market disruptions are impossible to predict, but could be substantial.

Depository Receipts Risk. The Fund may hold the securities of non-U.S. companies in the form of American Depositary Receipts (“ADRs”). ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Foreign Investment Risk. The Fund faces the risks inherent in foreign investing. Adverse political, economic or social developments could undermine the value of the Fund’s foreign investments, prevent the Fund from realizing the full value of its foreign investments or prevent the Fund from selling foreign securities it holds. Financial reporting standards for companies based in foreign markets differ from those in the United States. Additionally, foreign securities markets generally are smaller and less liquid than U.S. markets. Foreign governments may restrict investment by foreigners, limit withdrawal of trading profit or currency from the country, restrict currency exchange or seize foreign investments. In addition, the Fund may be limited in its ability to exercise its legal rights or enforce a counterparty’s legal obligations in certain jurisdictions outside of the U.S. The foreign investments of the Fund may also be subject to foreign withholding taxes. Foreign brokerage commissions and other fees are generally higher than those for U.S. investments, and the transactions and custody of foreign assets may involve delays in payment, delivery or recovery of money or investments. Foreign markets can have liquidity risks beyond those typical of U.S. markets. Because foreign exchanges generally are smaller and less liquid than U.S. exchanges, buying and selling foreign investments can be more difficult and costly. Relatively small transactions can sometimes materially affect the price and availability of securities. In certain situations, it may become virtually impossible to sell an investment at a price that approaches portfolio management’s estimate of its value. For the same reason, it may at times be difficult to value the Fund’s foreign investments. In addition, because non-U.S. markets may be open on days when the Fund does not price its shares, the value of the foreign securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s Shares.

Initial Public Offering (“IPO”) Risk. The Fund may invest in companies that have recently completed an initial public offering. The stocks of such companies are unseasoned equities lacking a trading history, a track record of reporting to investors and widely available research coverage. IPOs are thus often subject to extreme price volatility and speculative trading. In addition, IPOs share similar illiquidity risks of private equity and venture capital. The free float shares held by the public in an IPO are typically a small percentage of the market capitalization. The ownership of many IPOs often includes large holdings by venture capital and private equity investors who seek to sell their shares in the public market in the months following an IPO when shares restricted by lock-up are released, causing greater volatility and possible downward pressure during the time that locked-up shares are released.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. While the Fund and Adviser have established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Further, the Fund cannot control the cybersecurity plans and systems of the Fund’s Index Provider and other service providers, market makers, or issuers of securities in which the Fund invests. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyberattacks or other cyber-failures.

|
| Prospectus [Line Items] |
|
| Risk [Text Block] |

|
Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates, which may negatively affect the value of debt instruments held by the Fund and have a negative impact on the Fund’s performance and NAV. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses. During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are low and the market prices for portfolio securities have increased, the Fund may have a very low or even negative yield. A low or negative yield would cause the Fund to lose money in certain conditions and over certain time periods. An increase in interest rates will generally cause the value of securities held by the Fund to decline, may lead to heightened volatility in the fixed-income markets and may adversely affect the liquidity of certain fixed-income investments, including those held by the Fund. Additionally, as a result of increasing interest rates, reserves held by banks and other financial institutions in bonds and other debt securities could face a significant decline in value relative to deposits and liabilities, which coupled with general economic headwinds resulting from a changing interest rate environment, creates liquidity pressures at such institutions. As a result, certain sectors of the credit markets could experience significant declines in liquidity, and it is possible that the Fund will not be able to manage this risk effectively.

Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s Shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF Shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.

Although the Fund’s Shares are listed on a national securities exchange, The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.

Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the Fund, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

Affiliated Fund Risk. Affiliated fund risk is the risk that the Adviser may select investments for the Fund based on its own financial interests or other business considerations rather than the Fund’s interests. The Adviser may be subject to potential conflicts of interest in selecting the Underlying Funds because the Underlying Funds pay an advisory fee to the Adviser based on their assets, the fees paid to the Adviser by some affiliated Underlying Funds may be higher than other Underlying Funds or the Underlying Funds may be in need of assets to enhance their appeal to other investors, liquidity and trading and/or to enable them to carry out their investment strategies. However, the Adviser is a fiduciary to the Fund and is legally obligated to act in the Fund’s best interest when selecting Underlying Funds.

Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in Fund redemption requests, including requests from shareholders who may own a significant percentage of the Fund’s Shares, which may be triggered by market turmoil or an increase in interest rates, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s Share price and increase the Fund’s liquidity risk, expenses and/or taxable distributions.

Index-Related Risk. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. The Index Provider may rely on various sources of information to assess the criteria of components of the Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor the Adviser can offer assurances that the Index Provider’s methodology or sources of information will provide an accurate assessment of included components. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Unusual market conditions or other unforeseen circumstances (such as natural disasters, political unrest or war) may impact the Index Provider or a third-party Provider and may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

Market Trading Risk. Each Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s portfolio holdings, which may cause a variance in the market price of Shares and their underlying NAV. In addition, an exchange or market may issue trading halts on specific securities or financial instruments. As a result, the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation/redemption process, potentially affect the price at which Shares trade in the secondary market, and/or result in the Fund
|
being unable to trade certain securities or financial instruments at all. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV.

|
Inflation-Indexed Bonds Risk. The principal value of an investment is not protected or otherwise guaranteed by virtue of the Fund’s investments in inflation-indexed bonds. Inflation-indexed bonds are fixed-income securities whose principal value is periodically adjusted according to the rate of inflation. If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds. For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal value. The value of inflation-indexed bonds is expected to change in response to changes in real interest rates. Real interest rates are tied to the relationship between nominal interest rates and the rate of inflation. If nominal interest rates increase at a faster rate than inflation, real interest rates may rise, leading to a decrease in value of inflation-indexed bonds. Short-term increases in inflation may lead to a decline in value. Any increase in the principal amount of an inflation-indexed bond will be considered taxable ordinary income, even though investors do not receive their principal until maturity. Periodic adjustments for inflation to the principal amount of an inflation-indexed bond may give rise to original issue discount, which will be includable in the Fund’s gross income. Due to original issue discount, the Fund may be required to make annual distributions to shareholders that exceed the cash received, which may cause the Fund to liquidate certain investments when it is not advantageous to do so. Also, if the principal value of an inflation-indexed bond is adjusted downward due to deflation, amounts previously distributed in the taxable year may be characterized in some circumstances as a return of capital.

|
Inflation-Linked Securities Risk. In general, the value of an inflation-linked security, including TIPS, will typically decrease when real interest rates (nominal interest rates reduced by the expected impact of inflation) increase and increase when real interest rates decrease. When inflation is negative or concerns over inflation are low, the value and income of inflation-linked securities could fall and result in losses for the Fund and during periods of very low inflation, the yield on an inflation-linked security may be negative. Conversely, during sustained periods of high inflation, the Fund’s yield should increase, which may not be repeated. Funds that invest heavily in inflation-linked securities do not always move in lockstep with inflation because they do not necessarily buy inflation-linked securities when they are originally issued or hold them until maturity. In addition, the accrual of inflation adjustments on the Fund’s holdings may significantly impact the current level of dividends actually paid to shareholders. Changes in inflation rates and/or interest rates may cause the Fund’s yield to vary substantially over time.

U.S. Treasury Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of a Fund’s U.S. Treasury obligations to decline.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries
|
to suffer data breaches, data corruption or lose operational functionality or prevent the Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. While the Fund and the Adviser have established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Further, the Fund cannot control the cybersecurity plans and systems of the Fund’s service providers, market makers, or issuers of securities in which the Fund invests. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

Derivatives Risk. A Fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates, which may negatively affect the value of debt instruments held by the Fund and have a negative impact on the Fund’s performance and NAV. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses. During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are low and the market prices for portfolio securities have increased, the Fund may have a very low or even negative yield. A low or negative yield would cause the Fund to lose money in certain conditions and over certain time periods. An increase in interest rates will generally cause the value of securities held by the Fund to decline, may lead to heightened volatility in the fixed-income markets and may adversely affect the liquidity of certain fixed-income investments, including those held by the Fund. Additionally, as a result of increasing interest rates, reserves held by banks and other financial institutions in bonds and other debt securities could face a significant decline in value relative to deposits and liabilities, which coupled with general economic headwinds resulting from a changing interest rate environment, creates liquidity pressures at such institutions. As a result, certain sectors of the credit markets could experience significant declines in liquidity, and it is possible that the Fund will not be able to manage this risk effectively.

These factors could have a significant impact on the Fund and its investments and could result in increased premiums or discounts to the Fund’s NAV. As a result, an investor could lose money over short periods due to short-term market movements or long periods of time during prolonged market downturns.

Options Risk. When the Fund purchases a call option, it receives, in return for the premium it pays, the right to buy from the writer of the option the underlying security at a specified price at any time before the option expires. The Fund purchases call options in anticipation of an increase in the market value of securities that it intends ultimately to buy. During the life of the call option, a Fund is able to buy the underlying security at the exercise price regardless of any increase in the market price of the underlying security. In order for a call option to result in a gain, the market price of the underlying security must exceed the sum of the exercise price, the premium paid, and transaction costs.

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Note Fund Shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
|
| |
●
|
Secondary Market
Trading Risk. Although Shares are intended to be listed on a national securities exchange (the “Exchange”), and may be
traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop
or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when
the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened
in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Shares trade on a stock exchange at prices at, above, or below the Fund’s most recent NAV. The Fund’s NAV is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Shares fluctuates continuously throughout trading hours on the exchange, based on both the relative market supply of, and demand for, the Shares and the underlying value of the Fund’s portfolio holdings. As a result, the trading prices of the Shares may deviate from the Fund’s NAV. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the
|
NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. Any of these factors, among others, may lead to the Shares trading at a premium or discount to NAV.

Fixed-Income Market Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities or duration will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Reinvestment Risk. Reinvestment risk is the risk that income from the Fund’s portfolio will decline if and when the Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio’s current earnings rate. A decline in income could negatively affect the market price of the Shares.

Reverse Repurchase Agreements Risk. Reverse repurchase agreements are a form of secured borrowing and subject the Fund to the risks associated with leverage, including exposure to potential gains and losses in excess of the amount invested, resulting in an increase in the speculative character of the Fund’s outstanding shares. Reverse repurchase agreements involve the risk that the investment return earned by the Fund (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Fund will decline below the price the Fund is obligated to pay to repurchase the securities, and that the other party may fail to return the securities in a timely manner or at all.

|
Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s portfolio holdings, which may cause a variance in the market price of Shares and their underlying NAV. In addition, an exchange or market may issue trading halts on specific securities or financial instruments. As a result, the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation/redemption process, potentially affect the price at which Shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments at all. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV.

U.S. Treasury Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund’s U.S. Treasury obligations to decline.

|

|
| Risk [Text Block] |
| |
●
|
Rate-Linked Derivatives Risk. The Fund’s exposure to derivatives tied to interest rates subjects the Fund to greater volatility than investments in traditional securities, such as stocks and bonds. Investing in derivatives tied to interest rates, including through options tied to the shape of the U.S. interest rate curve, can be extremely volatile. The value of such investments may fluctuate rapidly based on a variety of factors, including overall market movements; economic events and policies; changes in interest rates or inflation rates; changes in monetary and exchange control programs; war; acts of terrorism; natural disasters; and technological developments. The Fund is expected to benefit from the options it holds if long-term U.S. interest rates rise during the time period in which the Fund holds the options. However, if long-term U.S. interest rates decrease, the Fund will lose money on the options, up to the amount invested in option premiums, and underperform an otherwise identical bond fund that had not used such options. Rate-linked derivatives may lose money if interest rates change in a manner not anticipated by the Adviser. An increase in interest rates may cause the value of securities held directly or indirectly by the Fund to decline to the extent that the Fund’s hedging strategy is not effectively implemented. Even if the Fund is hedged against losses due to long-term interest rate increases linked to U.S. interest rates, outright interest rate increases may also lead to heightened volatility in the fixed-income markets and may positively affect the value of the Fund’s options while negatively impacting the Fund’s investments in U.S. Treasuries. The Fund could lose money on the options held by the Fund, and the present value of the Fund’s portfolio investments could decrease if inflation increases. These interest rate-linked options may also cause the Fund’s net asset value and returns to be more volatile and expose the Fund to increased counterparty risk. Fluctuations in the U.S. interest rate curve or the price of the options owned by the Fund could materially adversely affect an investment in the Fund. The Fund’s investments in options are not intended to mitigate duration and credit risk or other factors influencing the price of U.S. government bonds, which may have a greater impact on the bonds’ returns than interest rate risk. Moreover, to the extent that interest rate risk has been priced into the government bonds owned directly or indirectly by the Fund, the Fund could underperform other investments even during periods of rising long-term U.S. interest rates. There is no guarantee that the Fund will have positive performance even in environments of sharply rising U.S. interest rates. There is no guarantee that the Fund will be able to successfully mitigate interest rate risk.

Shorting U.S. Treasury Securities Risk. The Fund may seek short exposure to financial instruments such as U.S. Treasury securities. There is no guarantee that the returns on the Fund’s short positions will produce positive returns and the Fund could lose money if the short positions produce negative returns. U.S. Treasury prices are highly sensitive to changes in

interest rates and a decrease in yields (increase in prices) could result in significant losses for short positions. Shorting typically requires borrowing securities, which involves reliance on the availability of lenders and custodians.

U.S. Treasury and Agency Market Risk. The U.S. Treasury and agency market can be volatile, and the value of instruments correlated with these markets may fluctuate dramatically from day to day. U.S. Treasury and agency obligations may provide relatively lower returns than those of other securities. Similar to other debt instruments, U.S. Treasury and agency obligations are subject to debt instrument risk and interest rate risk. In addition, changes to the financial condition or credit rating of the U.S. Government may cause the value of U.S. Treasury and agency obligations to decline. U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. government and are generally considered to have negligible credit risk.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries
|
to suffer data breaches, data corruption or lose operational functionality or prevent the Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. While the Fund and the Adviser have established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Further, the Fund cannot control the cybersecurity plans and systems of the Fund’s service providers, market makers, or issuers of securities in which the Fund invests. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

Derivatives Risk. A Fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates, which may negatively affect the value of debt instruments held by the Fund and have a negative impact on the Fund’s performance and NAV. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses. During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are low and the market prices for portfolio securities have increased, the Fund may have a very low or even negative yield. A low or negative yield would cause the Fund to lose money in certain conditions and over certain time periods. An increase in interest rates will generally cause the value of securities held by the Fund to decline, may lead to heightened volatility in the fixed-income markets and may adversely affect the liquidity of certain fixed-income investments, including those held by the Fund. Additionally, as a result of increasing interest rates, reserves held by banks and other financial institutions in bonds and other debt securities could face a significant decline in value relative to deposits and liabilities, which coupled with general economic headwinds resulting from a changing interest rate environment, creates liquidity pressures at such institutions. As a result, certain sectors of the credit markets could experience significant declines in liquidity, and it is possible that the Fund will not be able to manage this risk effectively.

Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors including economic, political, financial, public health crises (such as epidemics or pandemics), war, acts of terrorism, recessions or other disruptive events (whether real, expected or perceived) in the local, regional or global markets. These factors could have a significant impact on the Fund and its investments and could result in increased premiums or discounts to the Fund’s NAV. As a result, an investor could lose money over short periods of time due to short-term market movements or long periods of time during prolonged market downturns.

Options Risk. When the Fund purchases a call option, it receives, in return for the premium it pays, the right to buy from the writer of the option the underlying security at a specified price at any time before the option expires. The Fund purchases call options in anticipation of an increase in the market value of securities that it intends ultimately to buy. During the life of the call option, a Fund is able to buy the underlying security at the exercise price regardless of any increase in the market price of the underlying security. In order for a call option to result in a gain, the market price of the underlying security must exceed the sum of the exercise price, the premium paid, and transaction costs.

ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:
|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as AP. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Note Fund Shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.
|
| |
●
|
Secondary
Market Trading Risk. Although Shares are intended to be listed on a national securities exchange (the “Exchange”),
and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for
them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress,
there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day
(discount). This risk is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Shares trade on a stock exchange at prices at, above, or below the Fund’s most recent NAV. The Fund’s NAV is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Shares fluctuates continuously throughout trading hours on the exchange, based on both the relative market supply of, and demand for, the Shares and the underlying value of the Fund’s portfolio holdings. As a result the trading prices of the Shares may deviate from the Fund’s NAV. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the
|
NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. Any of these factors, among others, may lead to the Shares trading at a premium or discount to NAV.

Fixed-Income Market Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities or duration will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Reverse Repurchase Agreements Risk. Reverse repurchase agreements are a form of secured borrowing and subject the Fund to the risks associated with leverage, including exposure to potential gains and losses in excess of the amount invested, resulting in an increase in the speculative character of the Fund’s outstanding shares. Reverse repurchase agreements involve the risk that the investment return earned by the Fund (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Fund will decline below the price the Fund is obligated to pay to repurchase the securities, and that the other party may fail to return the securities in a timely manner or at all.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s portfolio holdings, which may cause a variance in the market price of Shares and their underlying NAV. In addition, an exchange or market may issue trading halts on specific securities or financial instruments. As a result, the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation/redemption process, potentially affect the price at which Shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments at all. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV.

U.S. Treasury Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund’s U.S. Treasury obligations to decline.

|
Rate-Linked Derivatives Risk. The Fund’s exposure to derivatives tied to interest rates subjects the Fund to greater volatility than investments in traditional securities, such as stocks and bonds. Investing in derivatives tied to interest rates, including through options tied to the shape of the U.S. interest rate curve, can be extremely volatile. The value of such investments may fluctuate rapidly based on a variety of factors, including overall market movements; economic events and policies; changes in interest rates or inflation rates; changes in monetary and exchange control programs; war; acts of terrorism; natural disasters; and technological developments. The Fund is expected to benefit from the options it holds if long-term U.S. interest rates rise during the time period in which the Fund holds the options. However, if long-term U.S. interest rates decrease, the Fund will lose money on the options, up to the amount invested in option premiums, and underperform an otherwise identical bond fund that had not used such options. Rate-linked derivatives may lose money if interest rates change in a manner not anticipated by the Adviser. An increase in interest rates may cause the value of securities held directly or indirectly by the Fund to decline to the extent that the Fund’s hedging strategy is not effectively implemented. Even if the Fund is hedged against losses due to long-term interest rate increases linked to U.S. interest rates, outright interest rate increases may also lead to heightened volatility in the fixed-income markets and may positively affect the value of the Fund’s options while negatively impacting the Fund’s investments in U.S. Treasuries. The Fund could lose money on the options held by the Fund, and the present value of the Fund’s portfolio investments could decrease if inflation increases. These interest rate-linked options may also cause the Fund’s net asset value and returns to be more volatile and expose the Fund to increased counterparty risk. Fluctuations in the U.S. interest rate curve or the price of the options owned by the Fund could materially adversely affect an investment in the Fund. The Fund’s investments in options are not intended to mitigate duration and credit risk or other factors influencing the price of U.S. government bonds, which may have a greater impact on the bonds’ returns than interest rate risk. Moreover, to the extent that interest rate risk has been priced into the government bonds owned directly or indirectly by the Fund, the Fund could underperform other investments even during periods of rising long-term U.S. interest rates. There is no guarantee that the Fund will have positive performance even in environments of sharply rising U.S. interest rates. There is no guarantee that the Fund will be able to successfully mitigate interest rate risk.

U.S. Treasury prices are highly sensitive to changes in

While the Fund and the Adviser have established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Further, the Fund cannot control the cybersecurity plans and systems of the Fund’s service
|
providers, market makers, or issuers of securities in which the Fund invests. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

Derivatives Risk. A Fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates, which may negatively affect the value of debt instruments held by the Fund and have a negative impact on the Fund’s performance and NAV. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses. During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are low and the market prices for portfolio securities have increased, the Fund may have a very low or even negative yield. A low or negative yield would cause the Fund to lose money in certain conditions and over certain time periods. An increase in interest rates will generally cause the value of securities held by the Fund to decline, may lead to heightened volatility in the fixed-income markets and may adversely affect the liquidity of certain fixed-income investments, including those held by the Fund. Additionally, as a result of increasing interest rates, reserves held by banks and other financial institutions in bonds and other debt securities could face a significant decline in value relative to deposits and liabilities, which coupled with general economic headwinds resulting from a changing interest rate environment, creates liquidity pressures at such institutions. As a result, certain sectors of the credit markets could experience significant declines in liquidity, and it is possible that the Fund will not be able to manage this risk effectively.

During the life of the call option, a Fund is able to buy the underlying security at the exercise price regardless of any increase in the market price of the underlying security. In order for a call option to result in a gain, the market price of the underlying security must exceed the sum of the exercise price, the premium paid, and transaction costs.

●
|
Authorized Participants,
Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation
or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors
and may act as AP. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the
extent either of the following events occur, Fund Shares may trade at a material discount to net asset value (“NAV”) and
possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other
APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce
their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the
Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in
the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market
for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less
than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers
may be less willing to transact in Fund Shares.
|

●
|
Secondary Market
Trading Risk. Although Shares are intended to be listed on a national securities exchange (the “Exchange”), and may be
traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop
or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be times when
the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened
in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Shares trade on a stock exchange at prices at, above, or below the Fund’s most recent NAV. The Fund’s NAV is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Shares fluctuates continuously throughout trading hours on the exchange, based on both the relative market supply of, and demand for, the Shares and the underlying value of the Fund’s portfolio holdings. As a result the trading prices of the Shares may deviate from the Fund’s NAV. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. Any of these factors, among others, may lead to the Shares trading at a premium or discount to NAV.

The Adviser may be subject to potential conflicts of interest in selecting the Underlying Funds because the Underlying Funds pay an advisory fee to the Adviser based on their assets, the fees paid to the Adviser by some affiliated Underlying Funds may be higher than other Underlying Funds or the Underlying Funds may be in need of assets to enhance their appeal to other investors, liquidity and trading and/or to enable them to carry out their investment strategies. However, the Adviser is a fiduciary to the Fund and is legally obligated to act in the Fund’s best interest when selecting Underlying Funds.

Leverage Risk. Using derivatives can create leverage, which can amplify the effects of market volatility on the Fund’s share price and make the Fund’s returns more volatile. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations. The use of leverage may also cause the Fund to have higher expenses than those of other funds that do not use such techniques.

Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

|
Fixed-Income Market Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities or duration will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Reverse Repurchase Agreements Risk. Reverse repurchase agreements are a form of secured borrowing and subject the Fund to the risks associated with leverage, including exposure to potential gains and losses in excess of the amount invested, resulting in an increase in the speculative character of the Fund’s outstanding shares. Reverse repurchase agreements involve the risk that the investment return earned by the Fund (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Fund will decline below the price the Fund is obligated to pay to repurchase the securities, and that the other party may fail to return the securities in a timely manner or at all.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s portfolio holdings, which may cause a variance in the market price of Shares and their underlying NAV. In addition, an exchange or market may issue trading halts on specific securities or financial instruments. As a result, the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation/redemption process, potentially affect the price at which Shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments at all. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV.

U.S. Treasury Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund’s U.S. Treasury obligations to decline.

|
| Risk [Text Block] |

●
|
Rate-Linked Derivatives Risk. The Fund’s exposure to derivatives tied to interest rates subjects the Fund to greater volatility than investments in traditional securities, such as stocks and bonds. Investing in derivatives tied to interest rates, including through options tied to the shape of the U.S. interest rate curve, can be extremely volatile. The value of such investments may fluctuate rapidly based on a variety of factors, including overall market movements; economic events and policies; changes in interest rates or inflation rates; changes in monetary and exchange control programs; war; acts of terrorism; natural disasters; and technological developments. The Fund is expected to benefit from the options it holds if long-term U.S. interest rates rise during the time period in which the Fund holds the options. However, if long-term U.S. interest rates decrease, the Fund will lose money on the options, up to the amount invested in option premiums, and underperform an otherwise identical bond fund that had not used such options. Rate-linked derivatives may lose money if interest rates change in a manner not anticipated by the Adviser. An increase in interest rates may cause the value of securities held directly or indirectly by the Fund to decline to the extent that the Fund’s hedging strategy is not effectively implemented. Even if the Fund is hedged against losses due to long-term interest rate increases linked to U.S. interest rates, outright interest rate increases may also lead to heightened volatility in the fixed-income markets and may positively affect the value of the Fund’s options while negatively impacting the Fund’s investments in U.S. Treasuries. The Fund could lose money on the options held by the Fund, and the present value of the Fund’s portfolio investments could decrease if inflation increases. These interest rate-linked options may also cause the Fund’s net asset value and returns to be more volatile and expose the Fund to increased counterparty risk. Fluctuations in the U.S. interest rate curve or the price of the options owned by the Fund could materially adversely affect an investment in the Fund. The Fund’s investments in options are not intended to mitigate duration and credit risk or other factors influencing the price of U.S. government bonds, which may have a greater impact on the bonds’ returns than interest rate risk. Moreover, to the extent that interest rate risk has been priced into the government bonds owned directly or indirectly by the Fund, the Fund could underperform other investments even during periods of rising long-term U.S. interest rates. There is no guarantee that the Fund will have positive performance even in environments of sharply rising U.S. interest rates. There is no guarantee that the Fund will be able to successfully mitigate interest rate risk.

Shorting U.S. Treasury Securities Risk. The Fund may seek short exposure to financial instruments such as U.S. Treasury securities. There is no guarantee that the returns on the Fund’s short positions will produce positive returns and the Fund could lose money if the short positions produce negative returns. U.S. Treasury prices are highly sensitive to changes in interest rates and a decrease in yields (increase in prices) could result in significant losses for short positions. Shorting typically requires borrowing securities, which involves reliance on the availability of lenders and custodians. The failure of a counterparty to deliver the securities may impact the Fund’s execution of its strategy.

Derivatives Risk. A Fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships.

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates, which may negatively affect the value of debt instruments held by the Fund and have a negative impact on the Fund’s performance and NAV. Rising interest rates may prompt redemptions from the Fund, which may force the Fund to sell investments at a time when it is not advantageous to do so, which could result in losses. During periods of very low or negative interest rates, the Fund may be unable to maintain positive returns or pay dividends to Fund shareholders. Very low or negative interest rates may magnify interest rate risk. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, result in heightened market volatility and detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Additionally, under certain market conditions in which interest rates are low and the market prices for portfolio securities have increased, the Fund may have a very low or even negative yield. A low or negative yield would cause the Fund to lose money in certain conditions and over certain time periods. An increase in interest rates will generally cause the value of securities held by the Fund to decline, may lead to heightened volatility in the fixed-income markets and may adversely affect the liquidity of certain fixed-income investments, including those held by the Fund. Additionally, as a result of increasing interest rates, reserves held by banks and other financial institutions in bonds and other debt securities could face a significant decline in value relative to deposits and liabilities, which coupled with general economic headwinds resulting from a changing interest rate environment, creates liquidity pressures at such institutions. As a result, certain sectors of the credit markets could experience significant declines in liquidity, and it is possible that the Fund will not be able to manage this risk effectively.

These factors could have a significant impact on the Fund and its investments and could result in increased premiums or discounts to the Fund’s NAV.

During the life of the call option, a Fund is able to buy the underlying security at the exercise price regardless of any increase in the market price of the underlying security. In order for a call option to result in a gain, the market price of the underlying security must exceed the sum of the exercise price, the premium paid, and transaction costs.

●
|
Authorized Participants,
Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation
or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors
and may act as AP. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the
extent either of the following events occur, Fund Shares may trade at a material discount to net asset value (“NAV”) and
possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other
APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce
their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the
Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in
the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market
for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less
than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers
may be less willing to transact in Fund Shares.
|

●
|
Secondary Market
Trading Risk. Although Shares are intended to be listed on a national securities exchange (the “Exchange”), and
may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will
develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may be
times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is
heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Shares trade on a stock exchange at prices at, above, or below the Fund’s most recent NAV. The Fund’s NAV is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Shares fluctuates continuously throughout trading hours on the exchange, based on both the relative market supply of, and demand for, the Shares and the underlying value of the Fund’s portfolio holdings. As a result the trading prices of the Shares may deviate from the Fund’s NAV. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines. Any of these factors, among others, may lead to the Shares trading at a premium or discount to NAV.

Futures are standardized, exchange-traded contracts that obligate a purchaser to take delivery, and a seller to make delivery, of a specific amount of an asset at a specified future date at a specified price. The primary risks associated with the use of futures contracts and options are: (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the futures contract or option; (b) the possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the investment adviser’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; and (e) the possibility that the counterparty will default in the performance of its obligations.

|
Affiliated Fund Risk. Affiliated fund risk is the risk that the Adviser may select investments for the Fund based on its own financial interests or other business considerations rather than the Fund’s interests. The Adviser may be subject to potential conflicts of interest in selecting the Underlying Funds because the Underlying Funds pay an advisory fee to the Adviser based on their assets, the fees paid to the Adviser by some affiliated Underlying Funds may be higher than other Underlying Funds or the Underlying Funds may be in need of assets to enhance their appeal to other investors, liquidity and trading and/or to enable them to carry out their investment strategies. However, the Adviser is a fiduciary to the Fund and is legally obligated to act in the Fund’s best interest when selecting Underlying Funds.

Leverage Risk. Using derivatives can create leverage, which can amplify the effects of market volatility on the Fund’s share price and make the Fund’s returns more volatile. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations. The use of leverage may also cause the Fund to have higher expenses than those of other funds that do not use such techniques.

Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

|
Fixed-Income Market Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities or duration will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Reverse Repurchase Agreements Risk. Reverse repurchase agreements are a form of secured borrowing and subject the Fund to the risks associated with leverage, including exposure to potential gains and losses in excess of the amount invested, resulting in an increase in the speculative character of the Fund’s outstanding shares. Reverse repurchase agreements involve the risk that the investment return earned by the Fund (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Fund will decline below the price the Fund is obligated to pay to repurchase the securities, and that the other party may fail to return the securities in a timely manner or at all.

|
Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s portfolio holdings, which may cause a variance in the market price of Shares and their underlying NAV. In addition, an exchange or market may issue trading halts on specific securities or financial instruments. As a result, the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation/redemption process, potentially affect the price at which Shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments at all. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV.

U.S. Treasury Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund’s U.S. Treasury obligations to decline.

●
|
Rate-Linked Derivatives Risk. The Fund’s exposure to derivatives tied to interest rates subjects the Fund to greater volatility than investments in traditional securities, such as stocks and bonds. Investing in derivatives tied to interest rates, including through options tied to the shape of the U.S. interest rate curve, can be extremely volatile. The value of such
|
investments may fluctuate rapidly based on a variety of factors, including overall market movements; economic events and policies; changes in interest rates or inflation rates; changes in monetary and exchange control programs; war; acts of terrorism; natural disasters; and technological developments. The Fund is expected to benefit from the options it holds if long-term U.S. interest rates rise during the time period in which the Fund holds the options. However, if long-term U.S. interest rates decrease, the Fund will lose money on the options, up to the amount invested in option premiums, and underperform an otherwise identical bond fund that had not used such options. Rate-linked derivatives may lose money if interest rates change in a manner not anticipated by the Adviser. An increase in interest rates may cause the value of securities held directly or indirectly by the Fund to decline to the extent that the Fund’s hedging strategy is not effectively implemented. Even if the Fund is hedged against losses due to long-term interest rate increases linked to U.S. interest rates, outright interest rate increases may also lead to heightened volatility in the fixed-income markets and may positively affect the value of the Fund’s options while negatively impacting the Fund’s investments in U.S. Treasuries. The Fund could lose money on the options held by the Fund, and the present value of the Fund’s portfolio investments could decrease if inflation increases. These interest rate-linked options may also cause the Fund’s net asset value and returns to be more volatile and expose the Fund to increased counterparty risk. Fluctuations in the U.S. interest rate curve or the price of the options owned by the Fund could materially adversely affect an investment in the Fund. The Fund’s investments in options are not intended to mitigate duration and credit risk or other factors influencing the price of U.S. government bonds, which may have a greater impact on the bonds’ returns than interest rate risk. Moreover, to the extent that interest rate risk has been priced into the government bonds owned directly or indirectly by the Fund, the Fund could underperform other investments even during periods of rising long-term U.S. interest rates. There is no guarantee that the Fund will have positive performance even in environments of sharply rising U.S. interest rates. There is no guarantee that the Fund will be able to successfully mitigate interest rate risk.

Shorting U.S. Treasury Securities Risk. The Fund may seek short exposure to financial instruments such as U.S. Treasury securities. There is no guarantee that the returns on the Fund’s short positions will produce positive returns and the Fund could lose money if the short positions produce negative returns. U.S. Treasury prices are highly sensitive to changes in interest rates and a decrease in yields (increase in prices) could result in significant losses for short positions. Shorting typically requires borrowing securities, which involves reliance on the availability of lenders and custodians. The failure of a counterparty to deliver the securities may impact the Fund’s execution of its strategy.

U.S. Treasury and Agency Market Risk. The U.S. Treasury and agency market can be volatile, and the value of instruments correlated with these markets may fluctuate dramatically from day to day. U.S. Treasury and agency obligations may provide relatively lower returns than those of other securities. Similar to other debt instruments, U.S. Treasury and agency obligations are subject to debt instrument risk and interest rate risk. In addition, changes to the financial condition or credit rating of the U.S. Government may cause the value of U.S. Treasury and agency obligations to decline. U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. government and are generally considered to have negligible credit risk. Securities issued or guaranteed by federal agencies or authorities and U.S. government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. government.

Counterparty Risk. Counterparty risk is the risk that a counterparty to a financial instrument held by the Fund or by a special purpose or structured vehicle invested in the Fund may become insolvent or otherwise fail to perform its obligations, and the Fund may obtain no or limited recovery of its investment, and any recovery may be significantly delayed. Because the Fund may enter into derivative agreements with a limited number of counterparties, this increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund, and as a result, the Fund may not be able to achieve its leveraged investment objective or rebalance properly, which may result in significant losses to the Fund, or the Fund may decide to change its leveraged investment objective. Counterparty risk may be heightened when there is significant volatility in the overall market or in the U.S. Treasury 3-Month Bill.

Credit Risk. The value of your investment in the Fund may change in response to changes in the credit ratings of the Fund’s portfolio securities, including with respect to the Underlying Funds. Generally, investment risk and price volatility increase as a security’s credit rating declines. The Adviser cannot guarantee the adequacy of the protection of the Fund’s interests, including the validity or enforceability of the loan and the maintenance of the anticipated priority and perfection of the applicable security interests. A credit agency’s rating represents the organization’s opinion as to the credit quality of a security but is not an absolute standard of quality or guarantee as to the creditworthiness of an issuer. Ratings from a credit agency present an inherent conflict of interest because the agency is paid by the entities whose securities they rate. Rating agencies may fail to move quickly enough to change ratings in response to changing circumstances, and a rating may not reflect the fine shadings of risks within a given quality grade. The financial condition of an issuer of a fixed income security held by the Fund or an Underlying Fund may cause it to default or become unable to pay interest or principal due on the security.

Cyber security risk is the risk of an unauthorized breach and access to the Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Underlying Funds, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Fund’s investors from purchasing, redeeming or exchanging Shares or receiving distributions. The Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, the Underlying Funds, and the Underlying Funds’ third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund, the Underlying Funds, or their respective investment advisers. Successful cyber-attacks or other cyber-failures or events affecting the Fund, the Underlying Funds or third-party service providers may adversely impact and cause financial losses to the Fund or its shareholders. The use of artificial intelligence and machine learning could exacerbate these risks or result in cyber security incidents that implicate personal data. Issuers of securities in which the Fund or the Underlying Funds invest are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

The use of derivatives involves risks different from, or greater than, the risks associated with investing in more traditional investments. Derivatives involve costs, may create leverage, and may be illiquid, volatile, and difficult to value. The Fund may not be able to close out or sell a derivative position at a particular time or at an anticipated price. The use of derivatives could also result in a loss if the counterparty to the transaction does not perform as promised, including because of such counterparty’s bankruptcy or insolvency. The investment results achieved by the use of derivatives by the Fund may not match or fully offset changes in the value of the underlying security, index or other reference asset that it was attempting to hedge or the investment opportunity the Fund was attempting to pursue.

During the life of the call option, the Fund is able to buy the underlying security at the exercise price regardless of any increase in the market price of the underlying security.

Convertible Securities Risk. The market price of a convertible security generally tends to behave like that of a regular debt security; that is, if market interest rates rise, the value of a convertible security usually falls. In addition, convertible securities are subject to the risk that the issuer will not be able to pay interest, principal or dividends when due, and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Because a convertible security derives a portion of its value from the common stock into which it may be converted, a convertible security is also subject to the same types of market and issuer risks that apply to the underlying common stock, including the potential for increased volatility in the price of the convertible security.

|
| |
●
|
Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to net asset value (“NAV”) and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Shares.
|

●
|
Secondary Market
Trading Risk. Although Shares are listed on a national securities exchange, The Nasdaq Stock Market, LLC (the “Exchange”),
and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them
will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, there may
be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk
is heightened in times of market volatility or periods of steep market declines.
|
| |
●
|
Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.

Preferred Stock Risk. A preferred stock may decline in price, or fail to pay dividends when expected, because the issuer experiences a decline in its financial status. Preferred stocks often behave like debt securities, but have a lower payment priority than the issuer’s bonds or other debt securities. Therefore, they may be subject to greater credit risk than those of debt securities. Preferred stocks also may be significantly less liquid than many other securities, such as corporate debt or common stock.

Futures Risk. Futures are standardized, exchange-traded contracts that obligate a purchaser to take delivery, and a seller to make delivery, of a specific amount of an asset at a specified future date at a specified price. The primary risks associated with the use of futures contracts and options are: (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the futures contract or option; (b) the possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the investment adviser’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; and (e) the possibility that the counterparty will default in the performance of its obligations.

|
High-Yield Securities Risk. Securities that are rated below investment-grade (commonly referred to as “junk bonds,” including those bonds rated lower than “BBB-” by S&P or “Baa3” by Moody’s), or are unrated, may be deemed speculative and may be more volatile than higher rated securities of similar maturity with respect to the issuer’s continuing ability to meet principal and interest payments. High-yield debt securities’ total return and yield may generally be expected to fluctuate more than the total return and yield of investment-grade debt securities. Therefore, the Fund’s investments in high-yield securities expose it to a substantial degree of credit risk. A real or perceived economic downturn or an increase in market interest rates could cause a decline in the value of high-yield debt securities, result in increased redemptions and/or result in increased portfolio turnover, which could result in a decline in the NAV of the Fund, reduce liquidity for certain investments and/or increase costs. High-yield debt securities are often thinly traded and can be more difficult to sell and value accurately than investment-grade debt securities because there may be no established secondary market. Investments in high-yield debt securities could increase liquidity risk for the Fund. In addition, the market for high-yield debt securities could experience sudden and sharp volatility, which is generally associated more with investments in stocks.

The Adviser may be subject to potential conflicts of interest in selecting the Underlying Funds because the Underlying Funds pay an advisory fee to the Adviser based on their assets, the fees paid to the Adviser by some affiliated Underlying Funds may be higher than other Underlying Funds or the Underlying Funds may be in need of assets to enhance their appeal to other investors, liquidity and trading and/or to enable them to carry out their investment strategies.

U.S. Government Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund’s U.S. Treasury obligations to decline.

●
|
Financial Sector Risk. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Changes in interest rates can have a disproportionate effect on the financial sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

|
Industrial Sector Risk. Companies in the industrial sector may be adversely affected by changes in the supply and demand for products and services, product obsolescence or discontinuance, claims for environmental damage or product liability and changes in general economic conditions, among other factors. Government regulation, word events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will also affect the performance of these companies.
|
| |
●
|
Utilities Sector Risk. Utility companies are affected by supply and demand, operating costs, government regulation, environmental factors, liabilities for environmental damage and general civil liabilities, and rate caps or rate changes. Although rate changes of a regulated utility usually fluctuate in approximate correlation with financing costs, due to political and regulatory factors, rate changes usually occur only following a delay after changes in financing costs. This factor will tend to favorably affect a regulated utility company’s earnings and dividends in times of decreasing costs, but conversely, will tend to adversely affect earnings and dividends when costs are rising. Certain utility companies have experienced full or partial de-regulation in recent years. These companies are frequently more similar to industrial companies in that they are subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. These opportunities may permit certain utility companies to earn more than their traditional regulated rates of return. Some companies, however, may be forced to defend their core business and may be less profitable. In addition, natural disasters, terrorist attacks, government intervention of other factors may render a utility company’s equipment unusable or obsolete and negatively impact profitability.

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in Fund redemption requests, including requests from shareholders who may own a significant percentage of the Shares, which may be triggered by market turmoil or an increase in interest rates, could cause the Fund to sell its holdings at a loss or at undesirable prices and adversely affect the Fund’s Share price and increase the Fund’s liquidity risk, Fund expenses and/or taxable distributions. To the extent the Fund invests in Underlying Funds that invest in fixed-income securities, the Fund will be further subject to fixed-income securities risks such as credit risk, duration risk, income risk, interest rate risk and rating agencies risk, as described herein.

Reverse repurchase agreements involve the risk that the investment return earned by the Fund (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Fund will decline below the price the Fund is obligated to pay to repurchase the securities, and that the other party may fail to return the securities in a timely manner or at all.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s portfolio holdings, which may cause a variance in the market price of Shares and their underlying
|
NAV. In addition, an exchange or market may issue trading halts on specific securities or financial instruments. As a result, the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation/redemption process, potentially affect the price at which Shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments at all. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV.

●
|
Premium/Discount Risk. The market price of the Fund’s Shares will generally fluctuate in accordance with changes in the Fund’s NAV as well as the relative supply of and demand for Shares on the Exchange. The Adviser cannot predict whether Shares will trade below, at, or above their NAV because the Shares trade on the Exchange at market prices and not at NAV. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for Shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that Shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAV), the Adviser believes that large discounts or premiums to the NAV of Shares should not be sustained. During stressed market conditions, the market for the Fund’s Shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying holdings, which could in turn lead to differences between the market price of the Fund’s Shares and their NAV and the bid/ask spread on the Fund’s Shares may widen.

●
|
Market Price Risk. Fund Shares are listed for trading on an exchange and are bought and sold in the secondary market at market prices. The market prices of Shares will fluctuate, in some cases materially, in response to changes in the NAV and supply and demand for Shares. As a result, the trading prices of Shares may deviate significantly from the NAV during periods of market volatility. The Adviser cannot predict whether Shares will trade above, below or at their NAV. Given the fact that Shares can be created and redeemed in Creation Units (defined below), the Adviser believes that large discounts or premiums to the NAV of Shares should not be sustained in the long-term. If market makers exit the business or are unable to continue making markets in Fund Shares, Shares may trade at a discount to NAV like closed-end fund shares and may even face delisting (that is, investors would no longer be able to trade Shares in the secondary market). Further, while the creation/redemption feature is designed to make it likely that Shares normally will trade close to the value of the Fund’s holdings, disruptions to creations and redemptions, including disruptions at market makers, APs or market participants, or during periods of significant market volatility, may result in market prices that differ significantly from the value of the Fund’s holdings. Although market makers will generally take advantage of differences between the NAV and the market price of Fund Shares through arbitrage opportunities, there is no guarantee that they will do so. In addition, the securities held by the Fund may be traded in markets that close at a different time than the exchange on which the Fund’s Shares trade. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the exchange is open but after the applicable market closing, fixing or settlement times, bid-ask spreads and the resulting premium or discount to the Shares’ NAV is likely to widen. Further, secondary markets may be subject to irregular trading activity, wide bid-ask spreads and extended trade settlement periods, which could cause a material decline in the Fund’s NAV. The Fund’s investment results are measured based upon the daily NAV of the Fund. Investors purchasing and selling Shares in the secondary market may not experience investment results consistent with those experienced by those APs creating and redeeming Shares directly with the Fund.

Prepayment and Extension Risk. When interest rates fall, issuers of high interest debt obligations may pay off the debts earlier than expected (prepayment risk), and the Fund may have to reinvest the proceeds at lower yields. When interest rates rise, issuers of lower interest debt obligations may pay off the debts later than expected (extension risk), thus keeping the Fund’s assets tied up in lower interest debt obligations. Ultimately, any unexpected behavior in interest rates could increase the volatility of the Fund’s Shares price and yield and could hurt fund performance. Prepayments could also create capital gains tax liability in some instances.

Distressed Securities Risk. Distressed securities are speculative and involve substantial risks in addition to the risks of investing in junk bonds. The Fund will generally not receive interest payments on the distressed securities and may incur costs to protect its investment. In addition, distressed securities involve the substantial risk that principal will not be repaid. These securities may present a substantial risk of default or may be in default at the time of investment. The Fund may incur additional expenses to the extent it is required to seek recovery upon a default in the payment of principal of or interest on its portfolio holdings. In any reorganization or liquidation proceeding relating to a portfolio company, the Fund may lose its entire investment or may be required to accept cash or securities with a value less than its original investment. Distressed securities and any securities received in an exchange for such securities may be subject to restrictions on resale.

Swaps can involve greater risks than direct investment in securities because swaps may be leveraged and are subject to counterparty risk (e.g., the risk of a counterparty’s defaulting on the obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value). Swaps may also be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

In addition, if the collateral securing CMOs or any third-party guarantees is insufficient to make payments, the Fund could sustain a loss.

Fixed-Income Securities
Risk. Fixed-income securities are subject to the risk of the issuer’s inability to meet principal and interest payments on
its obligations (i.e., credit risk) and are subject to price volatility resulting from, among other things, interest rate sensitivity,
market perception of the creditworthiness of the issuer, willingness of broker-dealers and other market participants to make markets
in the applicable securities, and general market liquidity (i.e., market risk). Lower rated fixed-income securities have greater volatility
because there is less certainty that principal and interest payments will be made as scheduled. There is a risk that a lack of liquidity
or other adverse credit market conditions may hamper the Fund’s ability to sell the debt securities in which it invests.

|
Interest-Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund or an Underlying Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s or an Underlying Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the Fund’s or an Underlying Fund’s yield and may increase the risk that, if followed by rising interest rates, the Fund’s performance will be negatively impacted. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the Fund or an Underlying Fund, resulting in a negative impact on the Fund’s performance and NAV. Any interest rate increases could cause the value of the Fund’s or an Underlying Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the Fund or an Underlying Fund, which may force the Fund or Underlying Fund to sell investments at a time when it is not advantageous to do so, which could result in losses. Interest rates in the United States and many other countries have risen in recent periods and may continue to remain elevated for the foreseeable future. Because longer-term inflationary pressure may result from the U.S. government’s fiscal policies, the Fund may experience higher interest rates over its investment horizon. Additionally, as a result of increasing interest rates, reserves held by banks and other financial institutions in bonds and other debt securities could face a significant decline in value relative to deposits and liabilities, which coupled with general economic headwinds resulting from a changing interest rate environment, creates liquidity pressures at such institutions. As a result, certain sectors of the credit markets could experience significant declines in liquidity, and it is possible that the Fund will not be able to manage this risk effectively.

Mortgage- and Asset-Backed Securities Risk. The Fund may invest in mortgage- and asset-backed securities (both commercial and residential), which represent “pools” of mortgages or other assets, including consumer loans or receivables held in trust. These securities, in most cases, are not backed by the full faith and credit of the U.S. government, and there can be no assurance that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so. These securities may be subject to liquidity risk as well as the risk of illiquidity and default on the underlying asset or mortgage, particularly during periods of economic downturn.

Restricted Securities/Rule 144A Securities Risk. The Fund may invest in securities offered pursuant to Rule 144A under the Securities Act of 1933, as amended (the “1933 Act”), which are restricted securities. They may be less liquid and more difficult to value than other investments because such securities may not be readily marketable in broad public markets. The Fund may not be able to sell a restricted security promptly or at a reasonable price. Although there is a substantial institutional market for Rule 144A securities, it is not possible to predict exactly how the market for Rule 144A securities will develop. A restricted security that was liquid at the time of purchase may subsequently become illiquid and its value may decline as a result. Restricted securities that are deemed illiquid will count towards the Fund’s 15% limitation on illiquid securities. In addition, transaction costs may be higher for restricted securities than for more liquid securities. The Fund may have to bear the expense of registering Rule 144A securities for resale and the risk of substantial delays in effecting the registration.

TBA Risk. In the TBA market, the seller agrees to deliver the mortgage-backed securities for an agreed-upon price on an agreed upon date, but makes no guarantee as to which or how many securities are to be delivered. The Fund relies on the seller to complete the transaction, and the seller’s failure to do so may cause the Fund to miss a price or yield considered advantageous to the Fund. In addition, the Fund bears the risk of loss in the event of the default or bankruptcy of the seller. The purchaser of TBA securities generally is subject to increased market risk relative to direct purchasers of mortgage-backed securities because the delivered securities may be less favorable than anticipated by the purchaser. Recently effective Financial Industry Regulatory Authority (“FINRA”) rules have implemented mandatory margin requirements for the TBA market that would require the Fund to post collateral in connection with its TBA transactions. There is no similar regulatory requirement applicable to the Fund’s TBA counterparties. The required collateralization of TBA trades could increase the cost of TBA transactions to the Fund and impose added operational complexity. Investments in TBAs may create leverage.

Variable Rate Securities Risk. Variable rate securities provide for a periodic adjustment in the interest rate paid on the securities. The rate adjustment intervals may be regular and range from daily up to annually, or may be based on an event, such as a change in the prime rate. Variable rate securities may be subject to greater liquidity risk than other debt securities, and there may be limitations on the Fund’s ability to sell the securities at any given time.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The use of artificial intelligence and machine learning could exacerbate these risks or result in cyber security incidents that implicate personal data. The Fund and Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

Market Risk — Market risk refers to the risk that the value of securities in the Fund’s portfolio may decline due to daily fluctuations in the securities markets, including fluctuation in interest rates, national and international economic conditions, and general equity market conditions.
Economies and financial markets throughout the world have become interconnected which increases the possibility that economic, financial or political events in one sector or region could have potentially adverse effects on global economies or markets. For example, Russia’s military invasion of Ukraine, the responses and sanctions by other countries, and the potential for wider military conflicts or war, could continue to have adverse effects on regional and global economies, and may further strain global supply chains, and negatively affect global growth and inflation. Natural or environmental disasters or climate related events, such as earthquakes, fires, floods, hurricanes and tsunamis, and widespread disease, including pandemics and epidemics, have been and can be highly disruptive to economies and the markets. For example, the outbreak of an infectious respiratory illness caused by a novel coronavirus, known as COVID-19, and efforts to contain its spread, have resulted, and may continue to result in labor shortages, supply chain disruptions, lower consumer demand for certain products and services, and significant disruptions to economies and markets, adversely affecting individual companies, sectors, industries, interest rates and investor sentiment.

Equity Securities Risk — The price of equity securities fluctuates based on changes in a company’s activities and financial condition and in overall market conditions. Economic, political, and financial conditions, or industry or economic trends or developments, may for varying periods of time cause volatility, illiquidity, or other potentially adverse effects in the markets. The Fund’s investments in equity securities expose it to sudden and unpredictable drops in value and the potential for extended periods of lackluster performance.

Foreign Securities Risk — Foreign investments may be affected by changes in a foreign country’s exchange rates, political and social instability, changes in economic or taxation policies, difficulties enforcing obligations, decreased liquidity, and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.

Depositary Receipts Risk — Depositary receipts are generally subject to the same risks as the foreign securities they evidence or into which they may be converted. In addition to investment risks associated with the underlying issuer, depositary receipts expose the Fund to additional risks associated with the non-uniform terms that apply to depositary receipt programs, credit exposure to the depository bank and to the sponsors and other parties with whom the depository bank establishes the programs, currency risk and liquidity risk. The issuers of unsponsored depositary receipts are not obligated to disclose information that is, in the United States, considered material. Therefore, there may be less information available regarding these issuers and there may not be a correlation between such information and the market value of the depositary receipts.

Operational Risk — The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties, or other third parties, failed or inadequate processes or technology or systems failures. The Fund and the Adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Sector Concentration Risk — Sector risk is the possibility that a certain sector may perform differently than other sectors or as the market as a whole. Although the Fund does not intend to concentrate its investments in any particular sector or sectors, the Fund may emphasize investments in one or more sectors, which may cause the Fund to have increased relative exposure to the price movements of those sectors. At times when the Fund emphasizes a particular sector, the value of its net assets will be more susceptible to the financial, market or economic events affecting that sector than would be the case for mutual funds that do not emphasize investment in a particular sector. This may increase the risk of loss associated with an investment in the Fund and increase the volatility of the Fund’s Share price. As of August 31, 2025, the Fund had approximately 64.6% of its net assets invested in stocks within the information technology sector. The values of securities of companies in the information technology sector may be significantly affected adversely by competitive pressures, short product cycles, aggressive pricing and rapid obsolescence of existing technologies and products.

Risk of Non-Diversification — The Fund is a non-diversified portfolio, which means that it has the ability to take larger positions in a smaller number of securities than a portfolio that is “diversified.” Non-diversification increases the risk that the Fund’s share price could decrease to a larger extent than a Fund that is diversified because of the poor performance of a single investment.
