Information Technology Sector Risk. To the extent the Fund invests a substantial portion of its assets in the information technology sector, the value of Fund shares may be particularly impacted by events that adversely affect the information technology sector, such as rapid changes in technology product cycles, product obsolescence, government regulation, and competition, and may fluctuate more than that of a fund that does not invest significantly in companies in the technology sector.

Equity Securities. In general, prices of equity securities are more volatile than those of fixed-income securities. U.S. and foreign stock markets, and equity securities of individual issuers, have experienced periods of substantial price volatility in the past and it is possible that they will do so again in the future. The prices of equity securities fluctuate, sometimes rapidly or widely, in response to activities specific to the issuer of the security as well as factors unrelated to the fundamental condition of the issuer, including general market, economic, political and public health conditions. During periods when equity securities experience heightened volatility, such as during periods of market, economic or financial uncertainty or distress, the Fund’s investments in equity securities are subject to heightened risks.
|
| |
The value of equity securities declines in response to perceived or actual adverse changes in the economy, economic outlook or financial markets; deterioration in investor sentiment; inflation, interest rate, currency, and commodity price fluctuations; adverse geopolitical, social or environmental developments; issuer- and sector-specific considerations; unexpected trading activity among retail investors; and other factors. Market conditions affect certain types of equity securities to a greater extent than other types of equity securities. If the stock market declines, the value of the Fund’s equity securities will also likely decline, which will result in a decrease in the value of your investment in the Fund. Although prices can rebound, there is no assurance that prices of the Fund’s equity securities will return to previous levels.

Securities Lending. The Fund may lend its portfolio securities to broker-dealers and other institutional borrowers. During the existence of a loan, the Fund will continue to receive the equivalent of the interest paid by the issuer on the securities loaned, or all or a portion of the interest on investment of the collateral, if any. The Fund may pay lending fees to such borrowers. Loans will only be made to firms that have been approved by the Adviser, and the Adviser or the securities lending agent will periodically monitor the financial condition of such firms while such loans are outstanding. Securities loans will only be made when the Adviser believes that the expected returns, net of expenses, justify the attendant risks. Securities loans currently are required to be secured continuously by collateral in cash, cash equivalents (such as money market instruments) or other liquid securities held by the custodian and maintained in an amount at least equal to the market value of the securities loaned. The Fund may engage in securities lending to generate income. Upon return of the loaned securities, the Fund would be required to return the related collateral to the borrower and may be required to liquidate portfolio securities in order to do so.

Tracking Error. Tracking error risk refers to the risk that the Fund’s performance may not match or correlate to that of the Index it attempts to track, either on a daily or aggregate basis. Tracking error may occur because of transaction costs, the Fund’s holding of cash, differences in accrual of dividends, changes to the Index or the need to meet new or existing regulatory requirements. Factors such as Fund expenses, imperfect correlation between the Fund’s investments and the Index, rounding of share prices, changes to the composition of the Index, regulatory policies, limitations on Fund investments imposed by Fund diversification and/or concentration policies, high portfolio turnover rate and the use of leverage all contribute to tracking error. Unlike the Fund, the returns of the Index are not reduced by investment and other operating expenses, including the trading costs associated with implementing changes to its portfolio of investments. Tracking error risk may cause the Fund’s performance to be less than expected. Tracking error risk may be heightened during times of market volatility, unusual market conditions or other abnormal circumstances. The Fund may be required to deviate its investments from the securities and relative weightings of the Index to comply with applicable laws and regulations or because of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates. If the Fund uses a sampling method of indexing, it may have a larger tracking error than if it used a replication method of indexing.

Index Related Risk. The Fund’s return may not track the return of the Index for a number of reasons and therefore may not achieve its investment objective. For example, the Fund may incur operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.
|
| |
In addition, the Fund’s return may differ from the return of the Index because of, among other things, pricing differences and the inability to purchase certain securities included in the Index due to regulatory or other restrictions. In addition, if the Fund uses a representative sampling approach (which is likely in connection with the Fund’s initial launch), the Fund may not be as well correlated with the return of the Index as when the Fund purchases all of the securities in the Index in the proportions in which they are represented in the Index. Errors in the construction or calculation of the Index may occur from time to time. Any such errors may not be identified and corrected by the index provider for some period of time, which may have an adverse impact on the Fund and its shareholders. The risk that the Fund may not track the performance of the Index may be heightened during times of increased market volatility or other unusual market conditions.

Passive Investment. The Fund is managed using a passive investment strategy and expects to hold common stocks of each company in the Index regardless of their current or projected performance. The Fund generally will not adjust its portfolio investments to attempt to take advantage of market opportunities or lessen the impact of a market decline or a decline in the performance of one or more issuers or for other reasons. Maintaining investments regardless of market conditions or the performance of individual investments could cause the Fund’s return to be lower than if the Fund employed an active strategy. Unusual market events or other abnormal circumstances may increase market volatility and may cause the characteristics of the Index components to vary from those expected under normal circumstances.

Market and Geopolitical Risk. The value of your investment in the Fund is based on the values of the Fund’s investments, which change due to economic, geopolitical and other events that affect the U.S. and global markets generally, as well as those that affect or are perceived or expected to affect particular regions, countries, industries, companies, issuers, sectors, asset classes or governments. These types of events may be sudden and unexpected, and could adversely affect the value (or income generated by) and liquidity of the Fund’s investments, which may in turn impact the Fund’s ability to sell securities and/or its ability to meet redemptions. The risks associated with these developments may be magnified if certain social, political, economic and other conditions and events (such as war, natural disasters or events, epidemics and pandemics, terrorism, conflicts, social unrest, recessions, inflation, interest rate changes, supply chain disruptions and the threat or actual imposition of tariffs, trade barriers and other protectionist or retaliatory measures) adversely interrupt or otherwise affect the global economy and financial markets. It is difficult to predict when events affecting the U.S. or global financial markets or economies may occur, the effects that such events may have and the duration of those effects (which may last for extended periods). These types of events may negatively impact broad segments of businesses and populations and have a significant and rapid negative impact on the performance or value of the Fund’s investments, adversely affect and increase the volatility of the Fund’s share price and exacerbate pre-existing risks to the Fund. The frequency and magnitude of resulting changes in the value of the Fund’s investments cannot be predicted.

New Fund Risk. A new fund’s performance may not represent how the fund is expected to or may perform in the long term.

As a new fund, the Fund will be more likely to use a representative sampling approach.

Foreign Securities. Investments in foreign markets entail special risks, such as currency, political (including geopolitical), economic and market risks and heightened risks, that may result in losses to the Fund. There also may be greater market volatility, less reliable financial information, less stringent investor protections and disclosure standards, higher transaction and custody costs and risks, decreased market liquidity and less government and exchange regulation associated with investments in foreign markets. In addition, investments in certain foreign markets that have historically been considered stable may become more volatile and subject to increased risk due to developments and changing conditions in such markets. Moreover, the growing interconnectivity of global economies and financial markets has increased the probability that adverse developments and conditions in one country or region will affect the stability of economies and financial markets in other countries or regions. Certain foreign markets may rely heavily on particular industries or foreign capital and are more vulnerable to diplomatic developments (including regional and global, military or other conflicts), the imposition of economic sanctions against a particular country or countries, organizations, companies, entities and/or individuals, changes in international trading patterns, trade barriers (including tariffs) and other protectionist or retaliatory measures. Investments in foreign markets may also be adversely affected by governmental interventions or other actions such as the imposition of capital controls, nationalization of companies or industries, expropriation of assets or the imposition of punitive taxes. The governments of certain countries may prohibit or impose substantial restrictions on foreign investing in their capital markets or in certain sectors or industries. In addition, a foreign government may limit or cause delay in the convertibility or repatriation of its currency which would adversely affect the U.S. dollar value and/or liquidity of investments denominated in that currency. Certain foreign investments may become less liquid and decline in value in response to market developments or adverse investor perceptions, or become illiquid after purchase by the Fund, particularly during periods of market, economic, political and social turmoil. When the Fund holds illiquid investments, its portfolio may be harder to value. In addition, the Fund’s investments in foreign issuers may be denominated in foreign currencies and therefore, to the extent unhedged, the value of those investments will fluctuate with U.S. dollar exchange rates. Economic sanctions or other similar measures may be, and have been, imposed against certain countries, organizations, companies, entities and/or individuals. Economic sanctions and other similar measures could, among other things, effectively restrict or eliminate the Fund’s ability to purchase or sell securities (in the sanctioned country and other markets), negatively impact the value or liquidity of the Fund’s investments, significantly delay or prevent the settlement of the Fund’s securities transactions, force the Fund to sell or otherwise dispose of investments at inopportune times or prices, or impair the Fund’s ability to meet its investment objective or invest in accordance with its investment strategies.

|
Foreign Currency Forward Exchange Contracts. To the extent the Fund seeks to hedge its foreign currency exposure by the use of foreign currency forward exchange contracts, the precise matching of the foreign currency forward exchange contract amounts and the value of the securities involved will not generally be possible because the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the date on which the contract is entered into and the date it matures. There is additional risk that such transactions may reduce or preclude the opportunity for gain if the value of the currency should move in the direction opposite to the position taken and that foreign currency forward exchange contracts create exposure to currencies in which the Fund’s securities are not denominated. The use of foreign currency forward exchange contracts involves the risks associated with derivatives and the risk of loss from the insolvency or bankruptcy of the counterparty to the contract or the failure of the counterparty to make payments or otherwise comply with the terms of the contract. Economic sanctions or other similar measures may be, and have been, imposed against certain countries, organizations, companies, entities and/or individuals.

Risk of Investing in Japan. To the extent the Fund invests a substantial portion of its assets in Japanese issuers, the Fund’s performance will be influenced by political, social and economic factors affecting Japan. In addition, investing in Japanese issuers subjects the Fund to legal, regulatory, currency, geographic and security risks that are specific to Japan. Japan’s economy is characterized by an aging demographic, a declining population, a large government debt and a highly regulated labor market, and depends heavily on international trade, oil and other commodity imports and government policy supporting its exports. Accordingly, the Japanese economy can be adversely affected by trade tariffs, other protectionist measures, competition from emerging economies, and the economic conditions of its trading partners. In addition, Japan’s relations with its neighbors have been strained at times, which could adversely affect its markets and economy. Japan is also vulnerable to natural disasters.

Tracking Error. Tracking error risk refers to the risk that the Fund’s performance may not match or correlate to that of the Index it attempts to track, either on a daily or aggregate basis. Tracking error may occur because of transaction costs, the Fund’s holding of cash, differences in accrual of dividends, changes to the Index or the need to meet new or existing regulatory requirements. Factors such as Fund expenses, imperfect correlation between the Fund’s investments and the Index, rounding of share prices, changes to the composition of the Index, regulatory policies, limitations on Fund investments imposed by Fund diversification and/or concentration policies, high portfolio turnover rate and the use of leverage all contribute to tracking error. Unlike the Fund, the returns of the Index are not reduced by investment and other operating expenses, including the trading costs associated with implementing changes to its portfolio of investments. Tracking error risk may cause the Fund’s performance to be less than expected. Tracking error risk may be heightened during times of market volatility, unusual market conditions or other abnormal circumstances. The Fund may be required to deviate its investments from the securities and relative weightings of the Index to comply with applicable laws and regulations or because of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

| |
In addition, the Fund’s return may differ from the return of the Index because of, among other things, pricing differences and the inability to purchase certain securities included in the Index due to regulatory or other restrictions. In addition, if the Fund uses a representative sampling approach (which is likely in connection with the Fund’s initial launch), the Fund may not be as well correlated with the return of the Index as when the Fund purchases all of the securities in the Index in the proportions in which they are represented in the Index. Errors in the construction or calculation of the Index may occur from time to time. Any such errors may not be identified and corrected by the index provider for some period of time, which may have an adverse impact on the Fund and its shareholders. The risk that the Fund may not track the performance of the Index may be heightened during times of increased market volatility or other unusual market conditions.

Passive Investment. The Fund is managed using a passive investment strategy and expects to hold common stocks of each company in the Index regardless of their current or projected performance. The Fund generally will not adjust its portfolio investments to attempt to take advantage of market opportunities or lessen the impact of a market decline or a decline in the performance of one or more issuers or for other reasons. Maintaining investments regardless of market conditions or the performance of individual investments could cause the Fund’s return to be lower than if the Fund employed an active strategy. Unusual market events or other abnormal circumstances may increase market volatility and may cause the characteristics of the Index components to vary from those expected under normal circumstances.

Market and Geopolitical Risk. The value of your investment in the Fund is based on the values of the Fund’s investments, which change due to economic, geopolitical and other events that affect the U.S. and global markets generally, as well as those that affect or are perceived or expected to affect particular regions, countries, industries, companies, issuers, sectors, asset classes or governments. These types of events may be sudden and unexpected, and could adversely affect the value (or income generated by) and liquidity of the Fund’s investments, which may in turn impact the Fund’s ability to sell securities and/or its ability to meet redemptions. The risks associated with these developments may be magnified if certain social, political, economic and other conditions and events (such as war, natural disasters or events, epidemics and pandemics, terrorism, conflicts, social unrest, recessions, inflation, interest rate changes, supply chain disruptions and the threat or actual imposition of tariffs, trade barriers and other protectionist or retaliatory measures) adversely interrupt or otherwise affect the global economy and financial markets. It is difficult to predict when events affecting the U.S. or global financial markets or economies may occur, the effects that such events may have and the duration of those effects (which may last for extended periods). These types of events may negatively impact broad segments of businesses and populations and have a significant and rapid negative impact on the performance or value of the Fund’s investments, adversely affect and increase the volatility of the Fund’s share price and exacerbate pre-existing risks to the Fund. The frequency and magnitude of resulting changes in the value of the Fund’s investments cannot be predicted.

Correlation to Index Risk. The Fund’s performance may not match or correlate to that of the Index and the Fund’s average duration may not match or correlate to the average duration of the Index. This may occur because of, among other things, transaction costs, the Fund’s holding of cash, differences in accrual of interest, changes to the Index or the need to meet new or existing regulatory requirements. Factors such as Fund expenses, lack of correlation between the Fund’s investments and the Index and imperfect correlation between the Fund’s average duration and the average duration of the Index, rounding of share prices, changes to the composition of the Index, regulatory policies, limitations on Fund investments imposed by Fund diversification and/or concentration policies, high portfolio turnover rate and the use of leverage all contribute to this risk. Unlike the Fund, the returns of the Index are not reduced by investment and other operating expenses, including the trading costs associated with implementing changes to its portfolio of investments and, accordingly, may cause the Fund’s performance to be less than expected or differ from the average duration of the Index. This risk may be heightened during times of market volatility, unusual market conditions or other abnormal circumstances. The Fund may be required to deviate its investments as compared to that of the Index to comply with applicable laws and regulations or because of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

Municipals. Because the Fund invests in municipal securities (also referred to as municipal obligations), the Fund may be susceptible to political, legislative, economic, regulatory, tax or other factors affecting issuers of these municipal securities, such as state and local governments and their agencies. To the extent that the Fund invests in municipal securities of issuers in the same state or economic sector, it could be more sensitive to economic, business or political developments that affect such state or sector. Municipal securities and their issuers may be more susceptible to downgrade, loss of revenue, default and bankruptcy during periods of economic stress. Municipal securities also involve the risk that an issuer may call the securities for redemption, which could force the Fund to reinvest the proceeds at a lower rate of interest. While interest earned on municipal securities is generally not subject to federal income tax, any interest earned on taxable municipal securities is fully taxable at the federal level and may be subject to state and/or local income tax.

Fixed-Income Securities. Fixed-income securities are subject to the risk of the issuer’s inability to meet principal and interest payments on its obligations (i.e., credit risk) and are subject to price volatility resulting from, among other things, interest rate sensitivity (i.e., interest rate risk), market perception of the creditworthiness of the issuer and general market liquidity (i.e., market risk). For example, a type of fixed-income securities in which the Fund may invest are corporate debt obligations. In addition to interest rate, credit and other risks, corporate debt obligations are also subject to factors directly related to the issuer, such as the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the marketplace, and by factors not directly related to the issuer, such as general market liquidity, economic conditions and inflation. The Fund may face a heightened level of interest rate risk in times of monetary policy change and/or uncertainty, such as when the Federal Reserve Board adjusts a quantitative easing program and/or changes rates. A changing interest rate environment increases certain risks, including the potential for periods of volatility, increased redemptions, shortened durations (i.e., prepayment risk) and extended durations (i.e., extension risk). The Fund is not limited as to the maturities (when a debt security provides its final payment) or durations (measure of interest rate sensitivity) of the securities in which it may invest but, the Fund seeks to approximate the average duration of the Index. Securities with longer durations are likely to be more sensitive to changes in interest rates, generally making them more volatile than securities with shorter durations. Lower rated fixed-income securities have greater volatility because there is less certainty that principal and interest payments will be made as scheduled. The Fund may be subject to certain liquidity risks that may result from the lack of an active market and the reduced number and capacity of traditional market participants to make a market in fixed-income securities.

U.S. Government Securities. Different types of U.S. government securities are subject to different levels of credit risk, including the risk of default, depending on the nature of the particular government support for that security. For example, a U.S. government-sponsored entity, such as Federal National Mortgage Association or Federal Home Loan Mortgage Corporation, although chartered or sponsored by an Act of Congress, may issue securities that are neither insured nor guaranteed by the U.S. Treasury and, therefore, are not backed by the full faith and credit of the United States. With respect to U.S. government securities that are not backed by the full faith and credit of the United States, there is the risk that the U.S. government will not provide financial support to such U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law. U.S. government securities are also subject to interest rate risks and can exhibit price fluctuations resulting from increases or decreases in interest rates.

Credit and Interest Rate Risk. Credit risk refers to the possibility that the issuer or guarantor of a security, or counterparty to a transaction, will be unable or unwilling or perceived to be unable or unwilling to make interest payments and/or repay the principal on its debt or otherwise honor its obligations, including the risk of default. In such instances, the value of the Fund could decline and the Fund could lose money. If an issuer’s, guarantor’s or counterparty’s financial condition worsens, the credit quality of the issuer, guarantor or counterparty may deteriorate. Credit ratings may not be an accurate assessment of financial condition, liquidity or credit risk. Although credit ratings may not accurately reflect the true credit risk of an instrument, a change in the credit rating of an instrument or an issuer, guarantor or counterparty, or the market’s perception of the creditworthiness of an instrument or issuer, guarantor or counterparty can have a rapid, adverse effect on the instrument’s value and liquidity and make it more difficult for the Fund to sell at an advantageous price or time. Interest rate risk refers to the decline in the value of a fixed-income security resulting from changes in the general level of interest rates. A wide variety of market and economic factors can cause interest rates to rise or fall, including central bank monetary policy, rising inflation, disinflation or deflation, and changes in general economic conditions. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up but the yield or income from new issuances of fixed-income securities generally decreases. Securities with longer durations will generally be more sensitive to changes in interest rates than securities with shorter durations. Fluctuations in interest rates may also affect the liquidity of and income generated by fixed-income instruments held by the Fund. The Fund may invest in variable and floating rate loans and other variable and floating rate securities. Although the value of these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk in times of monetary policy change and/or uncertainty, such as when the Federal Reserve Board adjusts a quantitative easing program and/or changes rates. Changing interest rates may have unpredictable effects on the markets and may detract from Fund performance. A changing interest rate environment increases certain risks, including the potential for periods of market volatility, increased redemptions, shortened durations (i.e., prepayment risk) and extended durations (i.e., extension risk).

Tracking Error. Tracking error risk refers to the risk that the Fund’s performance may not match or correlate to that of the Index it attempts to track, either on a daily or aggregate basis. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. Tracking error may occur because of, among other things, transaction costs, the Fund’s holding of cash, differences in accrual of dividends, changes to the Index or the need to meet new or existing regulatory requirements. Factors such as Fund expenses, imperfect correlation between the Fund’s investments and the Index, rounding of share prices, changes to the composition of the Index, regulatory policies, limitations on Fund investments imposed by Fund diversification and/or concentration policies, high portfolio turnover rate and the use of leverage all contribute to tracking error. Unlike the Fund, the returns of the Index are not reduced by investment and other operating expenses, including the trading costs associated with implementing changes to its portfolio of investments. Tracking error risk may cause the Fund’s performance to be less than expected. Tracking error risk may be heightened during times of market volatility, unusual market conditions or other abnormal circumstances. The Fund may be required to deviate its investments from the securities and relative weightings of the Index to comply with applicable laws and regulations or because of market restrictions or other legal reasons, including regulatory limits or other restrictions on securities that may be purchased by the Adviser and its affiliates.

Corporate Debt Obligations. Corporate debt obligations are fixed-income securities issued by corporations. The investment return of corporate debt obligations reflects interest earnings and changes in the market value of the security. The market value of a corporate debt obligation may be expected to rise and fall inversely with interest rates generally. There also exists the risk that the issuers of the securities may not be able to meet their obligations on interest or principal payments at the time called for by an instrument. Debtholders, as creditors, have a prior legal claim over common and preferred stockholders of the corporation as to both income and assets for the principal and interest due to the bondholder.
