A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in total annual fund operating expenses or in the expense example above, affect the Fund’s performance. Because the Fund is newly organized, portfolio turnover information is not yet available. Principal Investment Strategies The Fund is an actively managed exchange-traded fund (“ETF”) that seeks income and long term capital appreciation. The Fund’s strategy involves two components: (1) investing, directly or indirectly, in a portfolio of equity securities included in the BITA VistaShares Bitcoin Treasury Income Index (the “Index Strategy”); and (2) generating options premiums through an options portfolio (the “Options Strategies”). While the Fund is actively managed, its Index Strategy invests directly or indirectly, in a portfolio of equity securities contained in the BITA VistaShares Bitcoin Treasury Income Index (the “Index”) and generally seeks to track the composition and performance of the Index and its Options Strategies use options strategies applied to certain or all of the same portfolio of equity securities included in the Index (“Underlying Securities”). The Fund’s investment sub-adviser, VistaShares, LLC (“VistaShares”), uses investment discretion when implementing the Fund’s Options Strategies, as well as with respect to the Fund’s Index Strategy: (i) to determine whether, in VistaShares judgement, it is more favorable to the Fund for it to invest directly or synthetically in each security in the Index: and (ii) to reallocate the Fund’s portfolio holdings among Underlying Securities more frequently than the Index is rebalanced, when VistaShares believes doing so is in the Fund’s interest; and (iii) to the extent required for the Fund’s portfolio to comply with relevant regulatory requirements, invest in certain Underlying Securities in different proportions than they are currently weighted in the Index. In addition, the Fund will maintain an allocation to cash and/or U.S. Treasuries. The Fund’s strategies are overseen by the Adviser and VistaShares. Although Bitcoin (BTC) may be referred to as a “cryptocurrency” it is not yet widely accepted as a means of payment. The Fund does not invest directly in Bitcoin or any other digital assets. The Fund does not invest directly in derivatives to track the performance of Bitcoin or any other digital assets. The Fund does not invest in or seek direct exposure to the current “spot” or cash price of Bitcoin. Investors seeking direct exposure to the price of Bitcoin should consider an investment other than the Fund. Index Strategy The Fund invests directly or indirectly in the Underlying Securities that make up the Index. The Index is constructed by BITA GmbH (the “Index Provider”) using a rules-based methodology to track the performance of U.S.-listed companies with significant economic exposure to Bitcoin including cryptocurrency mining companies and companies that hold bitcoin as part of their treasury reserves or as an investment strategy. Index Overview: The Index’s initial universe consists of all publicly listed equity securities for which sufficient relevant information is available from public sources. The initial universe is screened using the following criteria, which are based on each company’s financial information for the most recent quarter: <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">A.</td> <td style="text-align: justify">Bitcoin Holding Requirement: To be eligible for inclusion, a company must hold at least 500 Bitcoin (BTC) on its balance sheet, as reported in its most recent financial disclosures.

Ordinary shares represent ownership in a company and typically give shareholders the right to vote and receive dividends. ADRs generally represent securities of foreign issuers listed on a U.S. exchange.</td></tr> </table> Companies that meet the foregoing screens are included in the Index. The Index is expected to be comprised of between 20 and 50 constituents; however, the number of constituents will vary over time. The Index is reconstituted and rebalanced quarterly (reconstitution means the Index is updated with new eligible companies based on current data; rebalancing means the weights of the companies in the Index are adjusted). In addition, the Index Provider may determine to substitute an Index constituent or make an extraordinary adjustment to the Index if it determines an extraordinary event has occurred. The determination date for regular adjustments (each a “Selection Day”) takes place on the first Friday of the rebalancing month. On each Selection Day, Index constituents are weighted according to the size of their Bitcoin (BTC) holdings, as publicly disclosed in their most recent financial reports. The Index is owned, calculated, administered, and disseminated by the Index Provider. The Index Provider is not affiliated with the Fund, the Adviser, or VistaShares. Direct/Synthetic Investments: The Fund will invest in the Underlying Securities either directly or indirectly (synthetically) using options and swaps (as described below). The Fund may utilize listed options to achieve synthetic exposure to the Fund’s portfolio securities. The Fund primarily employs short-dated (a month or less) in-the-money call options (options with strike prices below the current market price of the Underlying Securities, offering immediate intrinsic value). These options allow the Fund to synthetically replicate the performance of Underlying Securities without direct ownership. The Fund may also utilize other option strategies to achieve similar synthetic exposure, including purchasing call options and selling put options with identical strike prices. These derivatives strategies enable the Fund to respond flexibly to market conditions, liquidity constraints, or other factors that may affect the availability or pricing of swap agreements. For additional details about the Fund’s use of options, please refer to the section of the Prospectus entitled “Additional Information About the Fund.” In addition to options, the Fund may enter into swap agreements with financial institutions. These swap agreements are designed to synthetically replicate the performance of the securities in the Fund’s portfolio. The agreements will have specified durations, which will typically coincide with the Index’s reconstitution periods, but may range from one day to more than a year. Through each swap agreement, the Fund and the financial institution will agree to exchange the return (or differentials in rates of return) based on the performance of a particular security’s share price. The gross return (meaning the return before deducting any fees or expenses) to be exchanged or “swapped” between the parties is calculated with respect to a “notional amount”—a predetermined dollar value representing the Underlying Security that the Fund seeks to replicate synthetically. Options Strategies – Seeking Premiums The Fund employs various options strategies focused on generating premiums. Generally speaking, the Fund sells (writes) options on certain or all of its Underlying Securities, receiving premiums from counterparties that pay for the right to buy or sell at a set price. These premiums are an important driver of the Fund’s distributions. Premium levels are influenced by market conditions, particularly and the Adviser may adjust the Fund’s options strategies depending on the outlook for the Underlying Securities. While option selling may provide premium opportunities, it may also limit upside gains or increase downside risk. The options strategy most frequently utilized by the Fund is called a covered call spread, which is a type of selling credit spread. The Fund uses covered call spreads to earn premium by selling a call option while buying another at a higher strike, with both profit and loss capped. See the prospectus section titled “Additional Information About the Funds” for a list of the options strategies that the Fund may utilize, together with a description of each options strategy. Distributions may include a significant portion classified as return of capital (“ROC”). ROC generally represents a return of a shareholder’s invested capital rather than traditional income such as dividends or interest. For additional information about options premiums, please see the section in the Fund’s Prospectus titled “Additional Information About the Funds.” Collateral In addition, the Fund will hold cash and/or short-term U.S. Treasury securities. These securities serve a dual purpose: providing collateral for the Fund’s derivatives transactions and contributing to the Fund’s income generation. Fund Attributes Under normal circumstances, the Fund will invest at least 80% of the value of its net assets, plus borrowings for investment purposes, in a combination of equity securities included in the Index or derivatives instruments that provide exposure to those securities. For purposes of compliance with this investment policy, derivative instruments will be valued at their notional value. The Fund is classified as “non-diversified” under the 1940 Act. To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index. As of the date of this Prospectus, the Index is currently concentrated in the software industry. The Fund’s U.S.-listed equity securities may include securities of foreign issuers listed in the U.S. via American Depositary Receipts (“ADRs”). Under normal circumstances, the Fund will invest at least 80% of the value of its net assets, plus borrowings for investment purposes, in a combination of equity securities included in the Index or derivatives instruments that provide exposure to those securities. The Fund may not achieve its investment objective and there is a risk that you could lose all of your money invested in the Fund. Index Strategy Risks. The Fund’s strategy is linked to an Index maintained by the Index Provider that exercises complete control over the Index. The Index Provider may delay or add a rebalance date, which may adversely impact the performance of the Fund and its correlation to the Index. In addition, there is no guarantee that the methodology used by the Index Provider to identify constituents for the Index will achieve its intended result or positive performance. Errors in Index data, Index computations or the construction of the Index in accordance with its methodology may occur from time to time and may not be identified and/or corrected for a period of time or at all, which may have an adverse impact on the Fund. Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the 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 Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. Bitcoin Treasury Companies Risk. Companies that hold Bitcoin in their treasury face unique risks as a result of holding Bitcoin in their corporate treasury. The speculative perception of Bitcoin may overshadow the fundamentals of such companies, leading to exaggerated price movements based on hype or fear. Such companies may face criticism for adopting such a unique strategy, particularly during periods of declining Bitcoin prices, potentially harming their reputation and stock value. Companies may also face scrutiny or reputational damage for associating with Bitcoin, which some stakeholders view as controversial due to its environmental and illicit activity concerns. Companies with significant international operations may face challenges if jurisdictions impose restrictions on Bitcoin usage, trade or holdings. Companies holding Bitcoin may face accounting challenges, such as recording impairment losses when Bitcoin prices decline, even if the holdings are not sold. This can distort financial performance metrics. The value of the Fund’s investments in instruments that provide exposure to companies that hold Bitcoin in their treasury – and therefore the value of an investment in the Fund – could decline significantly and without warning. The value of the Fund’s investments will not correlate directly with Bitcoin because such companies engage in other businesses unrelated to Bitcoin and may derive a larger portion of their revenues from sources unrelated to Bitcoin holdings. If you are not prepared to accept significant and unexpected changes in the value of the Fund, you should not invest in the Fund. Digital Assets Risk. Digital assets like Bitcoin, designed as mediums of exchange, are still an emerging asset class. They operate independently of any central authority or government backing and are subject to regulatory changes and extreme price volatility. The trading platforms for digital assets are relatively new, largely unregulated, and thus more vulnerable to fraud and failures compared to traditional, regulated exchanges. Shutdowns of these platforms due to fraud, technical glitches, or security issues can significantly affect digital asset prices and market volatility. Digital Asset Markets Risk. The digital asset market, particularly Bitcoin, has experienced considerable volatility, leading to market disruptions and erosion of confidence among market participants. This instability and the resultant negative publicity could adversely affect the Fund’s reputation and trading prices. Ongoing market turbulence could significantly impact the value of the Fund’s share. Blockchain Technology Risk. Blockchain technology, which underpins Bitcoin and other digital assets, is relatively new, and many of its applications are untested. The adoption of blockchain and the development of competing platforms or technologies could affect its usage. Investments in companies or vehicles that utilize blockchain technology are subject to market volatility and may experience lower trading volumes compared to more established industries. Additionally, regulatory changes, internet disruptions, cybersecurity incidents, and intellectual property disputes could further affect the adoption and functionality of blockchain technology. Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. 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 or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks: Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund in particular, the value of the options contracts in which it invests are substantially influenced by the value of the relevant Underlying Securities. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly move with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in the values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. Additionally, as the Fund may continuously maintain indirect exposure to one or more of the Underlying Securities through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. Swap Agreements. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify counterparties for those swap agreements. Additionally, any financing, borrowing or other costs associated with using swap transactions may also have the effect of lowering the Fund’s return. The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a basket of securities. If an underlying security has a dramatic move that causes a material decline in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the swap transaction with the Fund. In that event, the Fund could be forced to invest directly in the underlying security at a potentially unfavorable time. Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy. Concentration Risk. The Fund’s investments will be concentrated in an industry or group of industries to approximately the same extent as the Index is so concentrated. In such event, the value of Shares may rise and fall more than the value of shares that invest in securities of companies in a broader range of industries. <div id="xdx_A81_eoef--RiskTextBlock_hoef--RiskAxis__custom--SoftwareIndustryRiskMember_zbHZyacXzYr3"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">●</td> <td style="text-align: justify">Software Industry Risk. The software industry can be significantly affected by intense competition, aggressive pricing, technological innovations, and product obsolescence. Companies in the software industry are subject to significant competitive pressures, such as aggressive pricing, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments and the potential for limited earnings and/or falling profit margins. These companies also face the risks that new services, equipment or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the value of their securities. Also, patent protection is integral to the success of many companies in this industry, and profitability can be affected materially by, among other things, the cost of obtaining (or failing to obtain) patent approvals, the cost of litigating patent infringement and the loss of patent protection for products (which significantly increases pricing pressures and can materially reduce profitability with respect to such products). In addition, many software companies have limited operating histories. Prices of these companies’ securities historically have been more volatile than other securities, especially over the short term.</td></tr> </table> Economic and 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. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets. ETF Risks. <p id="xdx_A8E_eoef--RiskTextBlock_hoef--RiskAxis__custom--AuthorizedParticipantsMarketMakersAndLiquidityProvidersConcentrationRiskMember_zJkV58UQ9Bx9" style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.5in; text-align: justify">Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “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. Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. <p id="xdx_A85_eoef--RiskTextBlock_hoef--RiskAxis__custom--SharesMayTradeAtPricesOtherThanNavMember_zlQ3tkbeQ6eh" style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.5in; text-align: justify">Shares May Trade at Prices Other Than NAV. 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) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Trading. Although Shares are listed on a national securities exchange, such as 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 trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing. Focused Portfolio Risk. The Fund will hold a relatively focused portfolio that may contain exposure to the securities of fewer issuers than the portfolios of other ETFs. Holding a relatively concentrated portfolio may increase the risk that the value of the Fund could go down because of the poor performance of one or a few investments. Foreign Securities Risk. Investments in securities or other instruments of non-U.S. issuers involve certain risks not involved in domestic investments and may experience more rapid and extreme changes in value than investments in securities of U.S. companies. Financial markets in foreign countries often are not as developed, efficient, or liquid as financial markets in the United States, and therefore, the prices of non-U.S. securities and instruments can be more volatile. In addition, the Fund will be subject to risks associated with adverse political and economic developments in foreign countries, which may include the imposition of economic sanctions. Generally, there is less readily available and reliable information about non-U.S. issuers due to less rigorous disclosure or accounting standards and regulatory practices. Investments in foreign companies’ securities, including investments via depositary receipts, are subject to special risks, including the following: <div id="xdx_A8B_eoef--RiskTextBlock_hoef--RiskAxis__custom--DepositaryReceiptRiskMember_zUQ0qEDYCS69"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">●</td> <td style="text-align: justify">Depositary Receipt Risk. Depositary receipts involve risks similar to those associated with investments in foreign securities and give rise to certain additional risks. Depositary receipts listed on U.S. or foreign exchanges are issued by banks or trust companies, and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (Underlying Shares). When the Fund invests in depositary receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the depositary receipts may not provide a return that corresponds precisely with that of the Underlying Shares.</td></tr> </table> High Portfolio Turnover Risk. The Fund may actively and frequently trade a significant portion of the Fund’s holdings. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains. Inflation Risk. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions, if any, may decline. Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. The Fund’s sub-adviser will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that the Fund will meet its investment objective. Market Capitalization Risk. <div id="xdx_A8B_eoef--RiskTextBlock_hoef--RiskAxis__custom--LargecapitalizationInvestingMember_zQZeXvxUSun6"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">●</td> <td style="text-align: justify">Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.</td></tr> </table> <div id="xdx_A87_eoef--RiskTextBlock_hoef--RiskAxis__custom--MidcapitalizationInvestingMember_zUiPfwW056E1"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">●</td> <td style="text-align: justify">Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies.

The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.</td></tr> </table> New Fund Risk. The Fund is a recently organized management investment company with no operating history. As a result, prospective investors do not have a track record or history on which to base their investment decisions. Newer Sub-Adviser Risk. VistaShares is a recently formed entity and has limited experience with managing an exchange-traded fund, which may limit the Sub-Adviser’s effectiveness . New Index Risk. The Index does not have a historical performance record, which may create additional risks for investing in the Fund. There can be no assurance that the Index will operate as intended during volatile market conditions or over the course of a full market cycle. Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio. Operational Risk. The Fund is subject to risks arising from various operational 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 and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund, Adviser, and Sub-Advisers seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks. Tax Risk. The Fund intends to elect and to qualify each year to be treated as a RIC under Subchapter M of the Code. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in total annual fund operating expenses or in the expense example above, affect the Fund’s performance. Because the Fund is newly organized, portfolio turnover information is not yet available. Principal Investment Strategies The Fund is an actively managed exchange-traded fund (“ETF”) that seeks income and long term capital appreciation. The Fund’s strategy involves two components: (1) investing, directly or indirectly, in a portfolio of equity securities included in the BITA VistaShares Ethereum Treasury Index (the “Index Strategy”); and (2) generating option premiums through an options portfolio (the “Options Strategies”). While the Fund is actively managed, its Index Strategy invests directly or indirectly, in a portfolio of equity securities contained in the BITA VistaShares Ethereum Treasury Index (the “Index”) and generally seeks to track the composition and performance of the Index and its Options Strategies use options strategies applied to certain or all of the same portfolio of equity securities included in the Index (“Underlying Securities”). The Fund’s investment sub-adviser, VistaShares, LLC (“VistaShares”), uses investment discretion when implementing the Fund’s Options Strategies, as well as with respect to the Fund’s Index Strategy: (i) to determine whether, in VistaShares judgement, it is more favorable to the Fund for it to invest directly or synthetically in each security in the Index: and (ii) to reallocate the Fund’s portfolio holdings among Underlying Securities more frequently than the Index is rebalanced, when VistaShares believes doing so is in the Fund’s interest; and (iii) to the extent required for the Fund’s portfolio to comply with relevant regulatory requirements, invest in certain Underlying Securities in different proportions than they are currently weighted in the Index.. In addition, the Fund will maintain an allocation to cash and/or U.S. Treasuries. The Fund’s strategies are overseen by the Adviser and VistaShares. Although Ether (ETH) may be referred to as a “cryptocurrency” it is not yet widely accepted as a means of payment. The Fund does not invest directly in Ether or any other digital assets. The Fund does not invest directly in derivatives to track the performance of Ether or any other digital assets. The Fund does not invest in or seek direct exposure to the current “spot” or cash price of Ether. Investors seeking direct exposure to the price of Ether should consider an investment other than the Fund. Index Strategy The Fund invests directly or indirectly in the Underlying Securities that make up the Index. The Index is constructed by BITA GmbH (the “Index Provider”) using a rules-based methodology to track the performance of U.S.-listed companies that are actively involved in the Ethereum ecosystem, including: (i) companies that hold Ethereum as part of their treasury reserves or as an investment, without actively engaging in staking Ether (ETH) on the Ethereum network via its proof-of-stake (PoS) process to help secure the blockchain and earn rewards; and (ii) companies that actively stake Ether (ETH) on the Ethereum network to facilitate the PoS process. Index Overview: The Index’s initial universe consists of all publicly listed equity securities for which sufficient relevant information is available from public sources. The initial universe is screened using the following criteria, which are based on each company’s financial information for the most recent quarter: <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">A.</td> <td style="text-align: justify">Ethereum Holding Requirement: To be eligible for inclusion, a company must hold at least 500 Ether (ETH) on its balance sheet, as reported in its most recent financial disclosures. However, if fewer than 20 securities meet all eligibility criteria, the crypto holdings threshold is reduced from 500 ETH to 250 ETH.</td></tr> </table> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">B.</td> <td style="text-align: justify">Major U.S. Stock Exchange: To be eligible for inclusion, a company’s shares must be listed in the Unites States on either the Nasdaq or New York Stock Exchange. </td></tr> </table> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">C.</td> <td style="text-align: justify">Ordinary Shares and ADRs: The Index includes only ordinary shares and American Depositary Receipts (“ADRs”) of eligible companies. Ordinary shares represent ownership in a company and typically give shareholders the right to vote and receive dividends. ADRs generally represent securities of foreign issuers listed on a U.S. exchange.</td></tr> </table> Companies that meet the foregoing screens are included in the Index. The Index is expected to be comprised of between 15 and 40 constituents; however, the number of constituents will vary over time. The Index is reconstituted and rebalanced quarterly (reconstitution means the Index is updated with new eligible companies based on current data; rebalancing means the weights of the companies in the Index are adjusted). In addition, the Index Provider may determine to substitute an Index constituent or make an extraordinary adjustment to the Index if it determines an extraordinary event has occurred. The determination date for regular adjustments (each a “Selection Day”) takes place on the first Friday of the rebalancing month. On each Selection Day, Index constituents are weighted according to the size of their Ether (ETH) holdings, as publicly disclosed in their most recent financial reports. The Index is owned, calculated, administered, and disseminated by the Index Provider. The Index Provider is not affiliated with the Fund, the Adviser, or VistaShares. Direct/Synthetic Investments: The Fund will invest in the Underlying Securities either directly or indirectly (synthetically) using options and swaps (as described below). The Fund may utilize listed options to achieve synthetic exposure to the Fund’s portfolio securities. The Fund primarily employs short-dated (a month or less) in-the-money call options (options with strike prices below the current market price of the Underlying Securities, offering immediate intrinsic value). These options allow the Fund to synthetically replicate the performance of Underlying Securities without direct ownership. The Fund may also utilize other option strategies to achieve similar synthetic exposure, including purchasing call options and selling put options with identical strike prices. These derivatives strategies enable the Fund to respond flexibly to market conditions, liquidity constraints, or other factors that may affect the availability or pricing of swap agreements. For additional details about the Fund’s use of options, please refer to the section of the Prospectus entitled “Additional Information About the Fund.” In addition to options, the Fund may enter into swap agreements with financial institutions. These swap agreements are designed to synthetically replicate the performance of the securities in the Fund’s portfolio. The agreements will have specified durations, which will typically coincide with the Index’s reconstitution periods, but may range from one day to more than a year. Through each swap agreement, the Fund and the financial institution will agree to exchange the return (or differentials in rates of return) based on the performance of a particular security’s share price. The gross return (meaning the return before deducting any fees or expenses) to be exchanged or “swapped” between the parties is calculated with respect to a “notional amount”—a predetermined dollar value representing the Underlying Security that the Fund seeks to replicate synthetically. Options Strategies – Seeking Premiums The Fund employs various options strategies focused on generating premiums. Generally speaking, the Fund sells (writes) options option premiums on certain or all of its Underlying Securities, receiving premiums from counterparties that pay for the right to buy or sell at a set price. These premiums are an important driver of the Fund’s distributions. Premium levels are influenced by market conditions, particularly volatility, and the Adviser may adjust the Fund’s options strategies depending on the outlook for the Underlying Securities. While option selling may provide premium opportunities, it may also limit upside gains or increase downside risk. The options strategy most frequently utilized by the Fund is called a covered call spread, which is a type of selling credit spread. The Fund uses covered call spreads to earn premium by selling a call option while buying another at a higher strike, with both profit and loss capped. See the prospectus section titled “Additional Information About the Funds” for a list of the options strategies that the Fund may utilize, together with a description of each options strategy. Distributions may include a significant portion classified as return of capital (“ROC”). ROC generally represents a return of a shareholder’s invested capital rather than traditional income such as dividends or interest. For additional information about options, please see the section in the Fund’s Prospectus titled “Additional Information About the Funds.” Collateral In addition, the Fund will hold cash and/or short-term U.S. Treasury securities. These securities serve a dual purpose: providing collateral for the Fund’s derivatives transactions and contributing to the Fund’s income generation. Fund Attributes Under normal circumstances, the Fund will invest at least 80% of the value of its net assets, plus borrowings for investment purposes, in a combination of equity securities included in the Index or derivatives instruments that provide exposure to those securities. For purposes of compliance with this investment policy, derivative instruments will be valued at their notional value. The Fund is classified as “non-diversified” under the 1940 Act. To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index. As of the date of this Prospectus, the Index is currently concentrated in the software industry. The Fund’s U.S.-listed equity securities may include securities of foreign issuers listed in the U.S. via American Depositary Receipts (“ADRs”). Under normal circumstances, the Fund will invest at least 80% of the value of its net assets, plus borrowings for investment purposes, in a combination of equity securities included in the Index or derivatives instruments that provide exposure to those securities. The Fund may not achieve its investment objective and there is a risk that you could lose all of your money invested in the Fund. Index Strategy Risks. The Fund’s strategy is linked to an Index maintained by the Index Provider that exercises complete control over the Index. The Index Provider may delay or add a rebalance date, which may adversely impact the performance of the Fund and its correlation to the Index. In addition, there is no guarantee that the methodology used by the Index Provider to identify constituents for the Index will achieve its intended result or positive performance. Errors in Index data, Index computations or the construction of the Index in accordance with its methodology may occur from time to time and may not be identified and/or corrected for a period of time or at all, which may have an adverse impact on the Fund. Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the 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 Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. Ethereum Treasury Companies Risk. Companies that hold Ether in their treasury face unique risks as a result of holding Ether in their corporate treasury. The speculative perception of Ether may overshadow the fundamentals of such companies, leading to exaggerated price movements based on hype or fear. Such companies may face criticism for adopting such a unique strategy, particularly during periods of declining Ether prices, potentially harming their reputation and stock value. Companies may also face scrutiny or reputational damage for associating with Ether, which some stakeholders view as controversial due to its environmental and illicit activity concerns. Companies with significant international operations may face challenges if jurisdictions impose restrictions on Ether usage, trade or holdings. Companies holding Ether may face accounting challenges, such as recording impairment losses when Ether prices decline, even if the holdings are not sold. This can distort financial performance metrics. The value of the Fund’s investments in instruments that provide exposure to companies that hold Ether in their treasury – and therefore the value of an investment in the Fund – could decline significantly and without warning. The value of the Fund’s investments will not correlate directly with Ether because such companies engage in other businesses unrelated to Ether and may derive a larger portion of their revenues from sources unrelated to Ether holdings. If you are not prepared to accept significant and unexpected changes in the value of the Fund, you should not invest in the Fund. Digital Assets Risk. Digital assets like Ether, designed as mediums of exchange, are still an emerging asset class. They operate independently of any central authority or government backing and are subject to regulatory changes and extreme price volatility. The trading platforms for digital assets are relatively new, largely unregulated, and thus more vulnerable to fraud and failures compared to traditional, regulated exchanges. Shutdowns of these platforms due to fraud, technical glitches, or security issues can significantly affect digital asset prices and market volatility. Digital Asset Markets Risk. The digital asset market, including Ether, has experienced considerable volatility, leading to market disruptions and erosion of confidence among market participants. This instability and the resultant negative publicity could adversely affect the Fund’s reputation and trading prices. Ongoing market turbulence could significantly impact the value of the Fund’s share. Blockchain Technology Risk. Blockchain technology, which underpins Ether, the Ethereum Network and other digital assets, is relatively new, and many of its applications are untested. The adoption of blockchain and the development of competing platforms or technologies could affect its usage. Investments in companies or vehicles that utilize blockchain technology are subject to market volatility and may experience lower trading volumes compared to more established industries. Additionally, regulatory changes, internet disruptions, cybersecurity incidents, and intellectual property disputes could further affect the adoption and functionality of blockchain technology. Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. 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 or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks: Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund in particular, the value of the options contracts in which it invests are substantially influenced by the value of the relevant Underlying Securities. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly move with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in the values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. Additionally, as the Fund may continuously maintain indirect exposure to one or more of the Underlying Securities through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. Swap Agreements. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify counterparties for those swap agreements. Additionally, any financing, borrowing or other costs associated with using swap transactions may also have the effect of lowering the Fund’s return. The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a basket of securities. If an underlying security has a dramatic move that causes a material decline in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the swap transaction with the Fund. In that event, the Fund could be forced to invest directly in the underlying security at a potentially unfavorable time. Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy. Concentration Risk. The Fund’s investments will be concentrated in an industry or group of industries to approximately the same extent as the Index is so concentrated. In such event, the value of Shares may rise and fall more than the value of shares that invest in securities of companies in a broader range of industries. <div id="xdx_A88_eoef--RiskTextBlock_hoef--RiskAxis__custom--SoftwareIndustryRiskMember_zj24hoHgGCxl"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">●</td> <td style="text-align: justify">Software Industry Risk. The software industry can be significantly affected by intense competition, aggressive pricing, technological innovations, and product obsolescence. Companies in the software industry are subject to significant competitive pressures, such as aggressive pricing, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments and the potential for limited earnings and/or falling profit margins. These companies also face the risks that new services, equipment or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the value of their securities. Also, patent protection is integral to the success of many companies in this industry, and profitability can be affected materially by, among other things, the cost of obtaining (or failing to obtain) patent approvals, the cost of litigating patent infringement and the loss of patent protection for products (which significantly increases pricing pressures and can materially reduce profitability with respect to such products). In addition, many software companies have limited operating histories. Prices of these companies’ securities historically have been more volatile than other securities, especially over the short term.</td></tr> </table> Economic and 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. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets. ETF Risks. <p id="xdx_A83_eoef--RiskTextBlock_hoef--RiskAxis__custom--AuthorizedParticipantsMarketMakersAndLiquidityProvidersConcentrationRiskMember_zOmLijFDYawd" style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.5in; text-align: justify">Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “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. Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. <p id="xdx_A81_eoef--RiskTextBlock_hoef--RiskAxis__custom--SharesMayTradeAtPricesOtherThanNavMember_zMRCNDYCN2L" style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.5in; text-align: justify">Shares May Trade at Prices Other Than NAV. 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) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Trading. Although Shares are listed on a national securities exchange, such as 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 trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing. Focused Portfolio Risk. The Fund will hold a relatively focused portfolio that may contain exposure to the securities of fewer issuers than the portfolios of other ETFs. Holding a relatively concentrated portfolio may increase the risk that the value of the Fund could go down because of the poor performance of one or a few investments. Foreign Securities Risk. Investments in securities or other instruments of non-U.S. issuers involve certain risks not involved in domestic investments and may experience more rapid and extreme changes in value than investments in securities of U.S. companies. Financial markets in foreign countries often are not as developed, efficient, or liquid as financial markets in the United States, and therefore, the prices of non-U.S. securities and instruments can be more volatile. In addition, the Fund will be subject to risks associated with adverse political and economic developments in foreign countries, which may include the imposition of economic sanctions. Generally, there is less readily available and reliable information about non-U.S. issuers due to less rigorous disclosure or accounting standards and regulatory practices. Investments in foreign companies’ securities, including investments via depositary receipts, are subject to special risks, including the following: <div id="xdx_A8B_eoef--RiskTextBlock_hoef--RiskAxis__custom--DepositaryReceiptRiskMember_zo9A9fofqak9"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">●</td> <td style="text-align: justify">Depositary Receipt Risk. Depositary receipts involve risks similar to those associated with investments in foreign securities and give rise to certain additional risks. Depositary receipts listed on U.S. or foreign exchanges are issued by banks or trust companies, and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (Underlying Shares). When the Fund invests in depositary receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the depositary receipts may not provide a return that corresponds precisely with that of the Underlying Shares.</td></tr> </table> High Portfolio Turnover Risk. The Fund may actively and frequently trade a significant portion of the Fund’s holdings. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains. Inflation Risk. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions, if any, may decline. Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. The Fund’s sub-adviser will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that the Fund will meet its investment objective. Market Capitalization Risk. <div id="xdx_A80_eoef--RiskTextBlock_hoef--RiskAxis__custom--LargecapitalizationInvestingMember_zRIUwAb8yu7l"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">●</td> <td style="text-align: justify">Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.</td></tr> </table> <div id="xdx_A80_eoef--RiskTextBlock_hoef--RiskAxis__custom--MidcapitalizationInvestingMember_zYTu80IaxiV8"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">●</td> <td style="text-align: justify">Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large-capitalization stocks or the stock market as a whole. </td></tr> </table> <div id="xdx_A8A_eoef--RiskTextBlock_hoef--RiskAxis__custom--SmallcapitalizationInvestingMember_zHVESbpx7n8b"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">●</td> <td style="text-align: justify">Small-Capitalization Investing. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.</td></tr> </table> New Fund Risk. The Fund is a recently organized management investment company with no operating history. As a result, prospective investors do not have a track record or history on which to base their investment decisions. Newer Sub-Adviser Risk. VistaShares is a recently formed entity and has limited experience with managing an exchange-traded fund, which may limit the Sub-Adviser’s effectiveness. New Index Risk. The Index does not have a historical performance record, which may create additional risks for investing in the Fund. There can be no assurance that the Index will operate as intended during volatile market conditions or over the course of a full market cycle. Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio. Operational Risk. The Fund is subject to risks arising from various operational 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 and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund, Adviser, and Sub-Advisers seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks. Tax Risk. The Fund intends to elect and to qualify each year to be treated as a RIC under Subchapter M of the Code. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in total annual fund operating expenses or in the expense example above, affect the Fund’s performance. Because the Fund is newly organized, portfolio turnover information is not yet available. Principal Investment Strategies The Fund is an actively managed exchange-traded fund (“ETF”) that seeks long term capital appreciation by investing, directly or indirectly, in a portfolio of equity securities included in the BITA VistaShares Ethereum Treasury Index (the “Index”) as described below. In addition, the Fund will maintain an allocation to cash and/or U.S. Treasuries. The Fund’s strategies are overseen by the Adviser and the Fund’s investment sub-adviser, VistaShares, LLC (“VistaShares”). Although Ether (ETH) may be referred to as a “cryptocurrency” it is not yet widely accepted as a means of payment. The Fund does not invest directly in Ether or any other digital assets. The Fund does not invest directly in derivatives to track the performance of Ether or any other digital assets. The Fund does not invest in or seek direct exposure to the current “spot” or cash price of Ether. Investors seeking direct exposure to the price of Ether should consider an investment other than the Fund. The Fund invests directly or indirectly in the equity securities that make up the Index (the “Underlying Securities”). The Index is constructed by BITA GmbH (the “Index Provider”) using a rules-based methodology to track the performance of U.S.-listed companies that are actively involved in the Ethereum ecosystem, including: (i) companies that hold Ethereum as part of their treasury reserves or as an investment, without actively engaging in staking Ether (ETH) on the Ethereum network via its proof-of-stake (PoS) process to help secure the blockchain and earn rewards; and (ii) companies that actively stake Ether (ETH) on the Ethereum network to facilitate the PoS process. While the Fund is actively managed, it generally seeks to track the composition and performance of the Index. VistaShares uses investment discretion: (i) to determine whether, in VistaShares judgement, it is more favorable to the Fund for it to invest directly or synthetically in each security in the Index: and (ii) to reallocate the Fund’s portfolio holdings among Underlying Securities more frequently than the Index is rebalanced, when VistaShares believes doing so is in the Fund’s interest; and (iii) to the extent required for the Fund’s portfolio to comply with relevant regulatory requirements, invest in certain Underlying Securities in different proportions than they are currently weighted in the Index.. In addition, the Fund will maintain an allocation to cash and/or U.S. Treasuries. Index Overview: The Index’s initial universe consists of all publicly listed equity securities for which sufficient relevant information is available from public sources. The initial universe is screened using the following criteria, which are based on each company’s financial information for the most recent quarter: <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">A.</td> <td style="text-align: justify">Ethereum Holding Requirement: To be eligible for inclusion, a company must hold at least 500 Ether (ETH) on its balance sheet, as reported in its most recent financial disclosures. However, if fewer than 20 securities meet all eligibility criteria, the crypto holdings threshold is reduced from 500 ETH to 250 ETH.</td></tr> </table> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">B.</td> <td style="text-align: justify">Major U.S. Stock Exchange: To be eligible for inclusion, a company’s shares must be listed in the Unites States on either the Nasdaq or New York Stock Exchange. </td></tr> </table> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">C.</td> <td style="text-align: justify">Ordinary Shares and ADRs: The Index includes only ordinary shares and American Depositary Receipts (“ADRs”) of eligible companies. Ordinary shares represent ownership in a company and typically give shareholders the right to vote and receive dividends. ADRs generally represent securities of foreign issuers listed on a U.S. exchange.</td></tr> </table> Companies that meet the foregoing screens are included in the Index. The Index is expected to be comprised of between 15 and 40 constituents; however, the number of constituents will vary over time. The Index is reconstituted and rebalanced quarterly (reconstitution means the Index is updated with new eligible companies based on current data; rebalancing means the weights of the companies in the Index are adjusted). In addition, the Index Provider may determine to substitute an Index constituent or make an extraordinary adjustment to the Index if it determines an extraordinary event has occurred. The determination date for regular adjustments (each a “Selection Day”) takes place on the first Friday of the rebalancing month. On each Selection Day, Index constituents are weighted according to the size of their Ether (ETH) holdings, as publicly disclosed in their most recent financial reports. The Index is owned, calculated, administered, and disseminated by the Index Provider. The Index Provider is not affiliated with the Fund, the Adviser, or VistaShares. Direct/Synthetic Investments: The Fund will invest in the Underlying Securities either directly or indirectly (synthetically) using options and swaps (as described below). The Fund may utilize listed options to achieve synthetic exposure to the Fund’s portfolio securities. The Fund primarily employs short-dated (a month or less) in-the-money call options (options with strike prices below the current market price of the Underlying Securities, offering immediate intrinsic value). These options allow the Fund to synthetically replicate the performance of Underlying Securities without direct ownership. The Fund may also utilize other option strategies to achieve similar synthetic exposure, including purchasing call options and selling put options with identical strike prices. These derivatives strategies enable the Fund to respond flexibly to market conditions, liquidity constraints, or other factors that may affect the availability or pricing of swap agreements. For additional details about the Fund’s use of options, please refer to the section of the Prospectus entitled “Additional Information About the Fund.” In addition to options, the Fund may enter into swap agreements with financial institutions. These swap agreements are designed to synthetically replicate the performance of the securities in the Fund’s portfolio. The agreements will have specified durations, which will typically coincide with the Index’s reconstitution periods, but may range from one day to more than a year. Through each swap agreement, the Fund and the financial institution will agree to exchange the return (or differentials in rates of return) based on the performance of a particular security’s share price. The gross return (meaning the return before deducting any fees or expenses) to be exchanged or “swapped” between the parties is calculated with respect to a “notional amount”—a predetermined dollar value representing the Underlying Security that the Fund seeks to replicate synthetically. Collateral In addition, the Fund will hold cash and/or short-term U.S. Treasury securities as collateral for the Fund’s derivatives transactions. Fund Attributes Under normal circumstances, the Fund will invest at least 80% of the value of its net assets, plus borrowings for investment purposes, in a combination of equity securities included in the Index or derivatives instruments that provide exposure to those securities. For purposes of compliance with this investment policy, derivative instruments will be valued at their notional value. The Fund is classified as “non-diversified” under the 1940 Act. To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index. As of the date of this Prospectus, is currently concentrated in the software industry . The Fund’s U.S.-listed equity securities may include securities of foreign issuers listed in the U.S. via American Depositary Receipts (“ADRs”). Under normal circumstances, the Fund will invest at least 80% of the value of its net assets, plus borrowings for investment purposes, in a combination of equity securities included in the Index or derivatives instruments that provide exposure to those securities. The Fund may not achieve its investment objective and there is a risk that you could lose all of your money invested in the Fund. Index Strategy Risks. The Fund’s strategy is linked to an Index maintained by the Index Provider that exercises complete control over the Index. The Index Provider may delay or add a rebalance date, which may adversely impact the performance of the Fund and its correlation to the Index. In addition, there is no guarantee that the methodology used by the Index Provider to identify constituents for the Index will achieve its intended result or positive performance. Errors in Index data, Index computations or the construction of the Index in accordance with its methodology may occur from time to time and may not be identified and/or corrected for a period of time or at all, which may have an adverse impact on the Fund. Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the 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 Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. Ethereum Treasury Companies Risk. Companies that hold Ether in their treasury face unique risks as a result of holding Ether in their corporate treasury. The speculative perception of Ether may overshadow the fundamentals of such companies, leading to exaggerated price movements based on hype or fear. Such companies may face criticism for adopting such a unique strategy, particularly during periods of declining Ether prices, potentially harming their reputation and stock value. Companies may also face scrutiny or reputational damage for associating with Ether, which some stakeholders view as controversial due to its environmental and illicit activity concerns. Companies with significant international operations may face challenges if jurisdictions impose restrictions on Ether usage, trade or holdings. Companies holding Ether may face accounting challenges, such as recording impairment losses when Ether prices decline, even if the holdings are not sold. This can distort financial performance metrics. The value of the Fund’s investments in instruments that provide exposure to companies that hold Ether in their treasury – and therefore the value of an investment in the Fund – could decline significantly and without warning. The value of the Fund’s investments will not correlate directly with Ether because such companies engage in other businesses unrelated to Ether and may derive a larger portion of their revenues from sources unrelated to Ether holdings. If you are not prepared to accept significant and unexpected changes in the value of the Fund, you should not invest in the Fund. Digital Assets Risk. Digital assets like Ether, designed as mediums of exchange, are still an emerging asset class. They operate independently of any central authority or government backing and are subject to regulatory changes and extreme price volatility. The trading platforms for digital assets are relatively new, largely unregulated, and thus more vulnerable to fraud and failures compared to traditional, regulated exchanges. Shutdowns of these platforms due to fraud, technical glitches, or security issues can significantly affect digital asset prices and market volatility. Digital Asset Markets Risk. The digital asset market, including Ether, has experienced considerable volatility, leading to market disruptions and erosion of confidence among market participants. This instability and the resultant negative publicity could adversely affect the Fund’s reputation and trading prices. Ongoing market turbulence could significantly impact the value of the Fund’s share. Blockchain Technology Risk. Blockchain technology, which underpins Ether, the Ethereum Network and other digital assets, is relatively new, and many of its applications are untested. The adoption of blockchain and the development of competing platforms or technologies could affect its usage. Investments in companies or vehicles that utilize blockchain technology are subject to market volatility and may experience lower trading volumes compared to more established industries. Additionally, regulatory changes, internet disruptions, cybersecurity incidents, and intellectual property disputes could further affect the adoption and functionality of blockchain technology. Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. 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 or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks: Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund in particular, the value of the options contracts in which it invests are substantially influenced by the value of the relevant Underlying Securities. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly move with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in the values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. Additionally, as the Fund may continuously maintain indirect exposure to one or more of the Underlying Securities through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. Swap Agreements. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify counterparties for those swap agreements. Additionally, any financing, borrowing or other costs associated with using swap transactions may also have the effect of lowering the Fund’s return. The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a basket of securities. If an underlying security has a dramatic move that causes a material decline in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the swap transaction with the Fund. In that event, the Fund could be forced to invest directly in the underlying security at a potentially unfavorable time. Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy. Concentration Risk. The Fund’s investments will be concentrated in an industry or group of industries to approximately the same extent as the Index is so concentrated. In such event, the value of Shares may rise and fall more than the value of shares that invest in securities of companies in a broader range of industries. <div id="xdx_A87_eoef--RiskTextBlock_hoef--RiskAxis__custom--SoftwareIndustryRiskMember_z0QSSrkyN6M5"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">●</td> <td style="text-align: justify">Software Industry Risk. The software industry can be significantly affected by intense competition, aggressive pricing, technological innovations, and product obsolescence. Companies in the software industry are subject to significant competitive pressures, such as aggressive pricing, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments and the potential for limited earnings and/or falling profit margins. These companies also face the risks that new services, equipment or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the value of their securities. Also, patent protection is integral to the success of many companies in this industry, and profitability can be affected materially by, among other things, the cost of obtaining (or failing to obtain) patent approvals, the cost of litigating patent infringement and the loss of patent protection for products (which significantly increases pricing pressures and can materially reduce profitability with respect to such products). In addition, many software companies have limited operating histories. Prices of these companies’ securities historically have been more volatile than other securities, especially over the short term.</td></tr> </table> Economic and 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. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets. ETF Risks. <p id="xdx_A85_eoef--RiskTextBlock_hoef--RiskAxis__custom--AuthorizedParticipantsMarketMakersAndLiquidityProvidersConcentrationRiskMember_zphv2H3fUuGl" style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.5in; text-align: justify">Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “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. Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. <p id="xdx_A82_eoef--RiskTextBlock_hoef--RiskAxis__custom--SharesMayTradeAtPricesOtherThanNavMember_zQaMOY6xoNec" style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.5in; text-align: justify">Shares May Trade at Prices Other Than NAV. 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) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Trading. Although Shares are listed on a national securities exchange, such as 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 trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing. Focused Portfolio Risk. The Fund will hold a relatively focused portfolio that may contain exposure to the securities of fewer issuers than the portfolios of other ETFs. Holding a relatively concentrated portfolio may increase the risk that the value of the Fund could go down because of the poor performance of one or a few investments. Foreign Securities Risk. Investments in securities or other instruments of non-U.S. issuers involve certain risks not involved in domestic investments and may experience more rapid and extreme changes in value than investments in securities of U.S. companies. Financial markets in foreign countries often are not as developed, efficient, or liquid as financial markets in the United States, and therefore, the prices of non-U.S. securities and instruments can be more volatile. In addition, the Fund will be subject to risks associated with adverse political and economic developments in foreign countries, which may include the imposition of economic sanctions. Generally, there is less readily available and reliable information about non-U.S. issuers due to less rigorous disclosure or accounting standards and regulatory practices. Investments in foreign companies’ securities, including investments via depositary receipts, are subject to special risks, including the following: <div id="xdx_A8A_eoef--RiskTextBlock_hoef--RiskAxis__custom--DepositaryReceiptRiskMember_zOdv5zeKR89"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">●</td> <td style="text-align: justify">Depositary Receipt Risk. Depositary receipts involve risks similar to those associated with investments in foreign securities and give rise to certain additional risks. Depositary receipts listed on U.S. or foreign exchanges are issued by banks or trust companies, and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (Underlying Shares). When the Fund invests in depositary receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the depositary receipts may not provide a return that corresponds precisely with that of the Underlying Shares.</td></tr> </table> Inflation Risk. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions, if any, may decline. Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. The Fund’s sub-adviser will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that the Fund will meet its investment objective. Market Capitalization Risk. <div id="xdx_A8D_eoef--RiskTextBlock_hoef--RiskAxis__custom--LargecapitalizationInvestingMember_zQGYruovZsZ1"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">●</td> <td style="text-align: justify">Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.</td></tr> </table> <div id="xdx_A89_eoef--RiskTextBlock_hoef--RiskAxis__custom--MidcapitalizationInvestingMember_zy1Md5iyB05e"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">●</td> <td style="text-align: justify">Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large-capitalization stocks or the stock market as a whole. </td></tr> </table> <div id="xdx_A86_eoef--RiskTextBlock_hoef--RiskAxis__custom--SmallcapitalizationInvestingMember_zVCD911rI28b"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">●</td> <td style="text-align: justify">Small-Capitalization Investing.

The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.</td></tr> </table> New Fund Risk. The Fund is a recently organized management investment company with no operating history. As a result, prospective investors do not have a track record or history on which to base their investment decisions. Newer Sub-Adviser Risk. VistaShares is a recently formed entity and has limited experience with managing an exchange-traded fund, which may limit the Sub-Adviser’s effectiveness. New Index Risk: The Index does not have a historical performance record, which may create additional risks for investing in the Fund. There can be no assurance that the Index will operate as intended during volatile market conditions or over the course of a full market cycle. Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio. Operational Risk. The Fund is subject to risks arising from various operational 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 and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund, Adviser, and Sub-Advisers seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks. Tax Risk. The Fund intends to elect and to qualify each year to be treated as a RIC under Subchapter M of the Code. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in total annual fund operating expenses or in the expense example above, affect the Fund’s performance. Because the Fund is newly organized, portfolio turnover information is not yet available. Principal Investment Strategies The Fund is an actively managed exchange-traded fund (“ETF”) that seeks income and long term capital appreciation. The Fund’s strategy involves two components: (1) investing, directly or indirectly, in a portfolio of equity securities of U.S.-listed companies whose initial public offering of shares (“IPO “) has occurred within the past twenty-four (24) months, at the time of purchase (the “Equity Strategy”); and (2) generating options premiums through an options portfolio (the “Options Strategies”). The Fund’s strategies are overseen by the Adviser and the Fund’s investment sub-adviser, VistaShares, LLC (“VistaShares”). Equity Strategy The Fund will primarily invest either directly or indirectly in a portfolio of publicly listed companies whose IPO has occurred within the past twenty-four (24) months, at the time of purchase (“Underlying Securities”). The Fund’s portfolio of Underlying Securities will generally include between 20 and 50 IPO companies; however, the number of companies will vary over time, at the discretion of the VistaShares. When deciding which Underlying Securities to buy, hold, or sell for the Fund, VistaShares generally seeks to invest in IPO companies that it believes, based on its own fundamental bottom-up analysis, have attractive growth potential, effective corporate governance, ability to further scale business operations and a strong management team with a disciplined approach to maintaining appropriate financial and balance sheet strength as their companies grow. In addition, VistaShares typically seeks to invest in IPO companies that, in its judgement, have demonstrated attractive year-over-year revenue growth, while maintaining sufficient short-term assets to cover the company’s current and foreseeable liabilities. Direct/Synthetic Investments: The Fund will invest in the Underlying Securities either directly or indirectly (synthetically) using options and swaps (as described below). The Fund may utilize listed options to achieve synthetic exposure to the Fund’s portfolio securities. The Fund primarily employs short-dated (a month or less) in-the-money call options (options with strike prices below the current market price of the Underlying Securities, offering immediate intrinsic value). These options allow the Fund to synthetically replicate the performance of Underlying Securities without direct ownership. The Fund may also utilize other option strategies to achieve similar synthetic exposure, including purchasing call options and selling put options with identical strike prices. These derivatives strategies enable the Fund to respond flexibly to market conditions, liquidity constraints, or other factors that may affect the availability or pricing of swap agreements. For additional details about the Fund’s use of options, please refer to the section of the Prospectus entitled “Additional Information About the Fund.” In addition to options, the Fund may enter into swap agreements with financial institutions. These swap agreements are designed to synthetically replicate the performance of the securities in the Fund’s portfolio. The agreements will have specified durations, which will typically coincide with the Index’s reconstitution periods, but may range from one day to more than a year. Through each swap agreement, the Fund and the financial institution will agree to exchange the return (or differentials in rates of return) based on the performance of a particular security’s share price. The gross return (meaning the return before deducting any fees or expenses) to be exchanged or “swapped” between the parties is calculated with respect to a “notional amount”—a predetermined dollar value representing the Underlying Security that the Fund seeks to replicate synthetically. Options Strategies – Seeking Premiums The Fund employs various options strategies focused on generating premiums. Generally speaking, the Fund sells (writes) options option premiums on certain or all of its Underlying Securities, receiving premiums from counterparties that pay for the right to buy or sell at a set price. These premiums are an important driver of the Fund’s distributions. Premium levels are influenced by market conditions, particularly volatility, and the Adviser may adjust the Fund’s options strategies depending on the outlook for the Underlying Securities. While option selling may provide premium opportunities, it may also limit upside gains or increase downside risk. The options strategy most frequently utilized by the Fund is called a covered call spread, which is a type of selling credit spread. The Fund uses covered call spreads to earn premium by selling a call option while buying another at a higher strike, with both profit and loss capped. See the prospectus section titled “Additional Information About the Funds” for a list of the options strategies that the Fund may utilize, together with a description of each options strategy. Distributions may include a significant portion classified as return of capital (“ROC”). ROC generally represents a return of a shareholder’s invested capital rather than traditional income such as dividends or interest. For additional information about options, please see the section in the Fund’s Prospectus titled “Additional Information About the Funds.” Collateral In addition, the Fund will hold cash and/or short-term U.S. Treasury securities. These securities serve a dual purpose: providing collateral for the Fund’s derivatives transactions and contributing to the Fund’s income generation. Fund Attributes Under normal circumstances, the Fund will invest at least 80% of the value of its net assets, plus borrowings for investment purposes, in a combination of equity securities of “IPO” companies or derivatives instruments that provide exposure to those securities. For purposes of compliance with this investment policy, derivative instruments will be valued at their notional value. For purposes of its 80% test, the Fund uses the following definitions of “IPO” companies: public listed companies whose initial public offering of shares has occurred within the past twenty-four (24) months, at the time of purchase by the Fund. The Fund is classified as “non-diversified” under the 1940 Act. The Fund’s U.S.-listed equity securities may include securities of foreign issuers listed in the U.S. via American Depositary Receipts (“ADRs”). Under normal circumstances, the Fund will invest at least 80% of the value of its net assets, plus borrowings for investment purposes, in a combination of equity securities of “IPO” companies or derivatives instruments that provide exposure to those securities. The Fund may not achieve its investment objective and there is a risk that you could lose all of your money invested in the Fund. Equity Market Risk. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from specific issuers. The equity securities held in the 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 Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. IPO Risk. The Fund may purchase securities of companies that are offered in an IPO. The risk exists that the market value of IPO shares will fluctuate considerably due to 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. 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. Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. 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 or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the Underlying Security and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks: Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. For the Fund in particular, the value of the options contracts in which it invests are substantially influenced by the value of the relevant Underlying Securities. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly move with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate at the underlying instrument. There may at times be an imperfect correlation between the movement in the values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. Additionally, as the Fund may continuously maintain indirect exposure to one or more of the Underlying Securities through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. Swap Agreements. The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify counterparties for those swap agreements. Additionally, any financing, borrowing or other costs associated with using swap transactions may also have the effect of lowering the Fund’s return. The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets or underlying securities or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a basket of securities. If an underlying security has a dramatic move that causes a material decline in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the swap transaction with the Fund. In that event, the Fund could be forced to invest directly in the underlying security at a potentially unfavorable time. Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (“clearing members”) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing member’s customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy. Economic and 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. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets. ETF Risks. <p id="xdx_A8A_eoef--RiskTextBlock_hoef--RiskAxis__custom--AuthorizedParticipantsMarketMakersAndLiquidityProvidersConcentrationRiskMember_zjkz5j2ek4vh" style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.5in; text-align: justify">Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “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. Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. <p id="xdx_A8E_eoef--RiskTextBlock_hoef--RiskAxis__custom--SharesMayTradeAtPricesOtherThanNavMember_zRn5Vukr3FOi" style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.5in; text-align: justify">Shares May Trade at Prices Other Than NAV. 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) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Trading. Although Shares are listed on a national securities exchange, such as 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 trading market for the Shares will develop or be maintained or that the Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. Shares trade on the Exchange at market price that may be below, at or above the Fund’s NAV. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. As a result, the Fund could be adversely affected and be unable to implement its investment strategies in the event of an unscheduled closing. Focused Portfolio Risk. The Fund will hold a relatively focused portfolio that may contain exposure to the securities of fewer issuers than the portfolios of other ETFs. Holding a relatively concentrated portfolio may increase the risk that the value of the Fund could go down because of the poor performance of one or a few investments. Foreign Securities Risk. Investments in securities or other instruments of non-U.S. issuers involve certain risks not involved in domestic investments and may experience more rapid and extreme changes in value than investments in securities of U.S. companies. Financial markets in foreign countries often are not as developed, efficient, or liquid as financial markets in the United States, and therefore, the prices of non-U.S. securities and instruments can be more volatile. In addition, the Fund will be subject to risks associated with adverse political and economic developments in foreign countries, which may include the imposition of economic sanctions. Generally, there is less readily available and reliable information about non-U.S. issuers due to less rigorous disclosure or accounting standards and regulatory practices. Investments in foreign companies’ securities, including investments via depositary receipts, are subject to special risks, including the following: <div id="xdx_A87_eoef--RiskTextBlock_hoef--RiskAxis__custom--DepositaryReceiptRiskMember_zmnYSnbvHALa"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">●</td> <td style="text-align: justify">Depositary Receipt Risk. Depositary receipts involve risks similar to those associated with investments in foreign securities and give rise to certain additional risks. Depositary receipts listed on U.S. or foreign exchanges are issued by banks or trust companies, and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (Underlying Shares). When the Fund invests in depositary receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the depositary receipts may not provide a return that corresponds precisely with that of the Underlying Shares.</td></tr> </table> High Portfolio Turnover Risk. The Fund may actively and frequently trade a significant portion of the Fund’s holdings. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains. Inflation Risk. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions, if any, may decline. Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. The Fund’s sub-adviser will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that the Fund will meet its investment objective. Market Capitalization Risk. <div id="xdx_A8B_eoef--RiskTextBlock_hoef--RiskAxis__custom--LargecapitalizationInvestingMember_zFbX3WPUTM8f"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">●</td> <td style="text-align: justify">Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.</td></tr> </table> <div id="xdx_A82_eoef--RiskTextBlock_hoef--RiskAxis__custom--MidcapitalizationInvestingMember_zLEqjrxbNueh"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">●</td> <td style="text-align: justify">Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large-capitalization stocks or the stock market as a whole. </td></tr> </table> <div id="xdx_A89_eoef--RiskTextBlock_hoef--RiskAxis__custom--SmallcapitalizationInvestingMember_zFP1NcOloAN1"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 30px"> </td> <td style="width: 30px">●</td> <td style="text-align: justify">Small-Capitalization Investing.

The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.</td></tr> </table> New Fund Risk. The Fund is a recently organized management investment company with no operating history. As a result, prospective investors do not have a track record or history on which to base their investment decisions. Newer Sub-Adviser Risk. VistaShares is a recently formed entity and has limited experience with managing an exchange-traded fund, which may limit the Sub-Adviser’s effectiveness. Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio. Operational Risk. The Fund is subject to risks arising from various operational 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 and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund, Adviser, and Sub-Advisers seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks. Tax Risk. The Fund intends to elect and to qualify each year to be treated as a RIC under Subchapter M of the Code. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to Shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.
