CDS provide exposure to the credit of one or more debt issuers referred to as &#x201c;reference entities.&#x201d; These instruments are designed to reflect changes in credit quality, including events of default. CDS are most commonly discussed in terms of buying or selling credit protection with respect to a reference entity. Because the Fund seeks to provide short exposure to credit, it will generally be a net buyer of credit protection with respect to North American high yield debt issuers. Buying credit protection is equivalent to being &#x201c;short&#x201d; credit. Index-based CDS provide credit exposure, through a single trade, to a basket of reference entities. A variety of high yield, index-based CDS with different characteristics are currently available in the marketplace with new issuances occurring periodically. Issuances typically vary in terms of &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;underlying reference entities and maturity and, thus, can &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;have significant differences in performance over time. The Fund intends to typically invest in new issuances of 5.25 year maturity North American high yield, index-based CDS, which are issued every six months on a 100-name basket, which names vary from issue to issue.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:-4.17%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:3pt;"&gt;U.S. Treasury Futures Contracts&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt; &#x2014; The Fund intends to invest in short U.S. Treasury futures contracts in order to obtain inverse exposure to interest rates, similar to the inverse interest rate exposure that would be present when shorting high yield bonds but is not present in CDS. U.S. Treasury futures contracts are standardized contracts traded on, or subject to the rules of, an exchange that call for the future delivery of a specified quantity and type of U.S. Treasury at a specified time and place or, alternatively, may call for cash settlement. The Fund will generally sell U.S. Treasury futures contracts as a substitute for a comparable market position in U.S. Treasury notes.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:-4.19%;"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Money Market Instruments&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014; The Fund expects that any cash balances maintained in connection with its use of derivatives will typically be held in high quality, short-term money market instruments, for example:&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:4pt;"&gt;U.S. Treasury Bills&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014;&#160;U.S. government securities that have initial maturities of one year or less, and are supported by the full faith and credit of the U.S. government.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:4pt;"&gt;Repurchase Agreements&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt; &#x2014; Contracts in which a seller of securities, usually U.S. government securities or other money market instruments, agrees to buy the securities back at a specified time and price.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to maintain inverse exposure to the high yield &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;market regardless of market conditions and without taking defensive positions in cash or other instruments in anticipation of periods favorable for the high yield market (which would generally be adverse market conditions for this Fund).

High yield debt instruments may be more sensitive to economic changes, political changes, or adverse developments specific to a company than other fixed income instruments. These &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;securities are subject to greater risk of loss, greater sensitivity &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;to economic changes, valuation difficulties, and a potential lack of a secondary or public market for securities. High yield debt instruments are considered speculative with respect to the issuer&#x2019;s continuing ability to make principal and interest payments and, therefore, such instruments generally involve greater risk of default or price changes than higher rated debt instruments. Furthermore, the transaction costs associated with the purchase and sale of high yield debt instruments may vary greatly depending upon a number of factors and may adversely affect the Fund&#x2019;s performance.&lt;/span&gt;</rr:RiskTextBlock>

Upon the occurrence of a credit event, the counterparty to the Fund will have an obligation to pay the full notional value of a defaulted reference entity less recovery value. Recovery values for CDS are generally determined via an auction process to determine the final price for a given reference entity. Although the Fund intends, as practicable, to obtain initial exposure primarily through centrally cleared CDS, an active market may not exist for any of the CDS in which the Fund invests or in the reference entities subject to the CDS. As a result, the Fund&#x2019;s ability to maximize returns or minimize losses on such CDS may be impaired. Other risks of CDS include difficulty in valuation due to the lack of pricing transparency and the risk that changes in the value of the CDS do not reflect changes in the credit quality of the underlying reference entities or may otherwise perform differently than expected given market conditions.&lt;/span&gt;</rr:RiskTextBlock>

A wide variety of factors can cause interest rates to fluctuate (e.g., central bank monetary policies, inflation rates, general economic conditions, etc.). Commonly, investments subject to interest rate risk will decrease in value when interest rates rise and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;increase in value when interest rates decline. A rising interest &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;rate environment may cause the value of debt instruments to decrease and adversely impact the liquidity of debt instruments. Without taking into account other factors, the value of securities with longer maturities typically fluctuates more in response to interest rate changes than securities with shorter maturities. These factors may cause the value of an investment in the Fund to change. Since the Fund seeks investment results that correspond to the inverse of the high yield market, the Fund&#x2019;s performance will generally be more favorable when interest rates rise and less favorable when interest rates decline.&lt;/span&gt;</rr:RiskTextBlock>

These risks include counterparty risk and liquidity risk. When the Fund uses derivatives, there may be imperfect correlation between the value of the reference asset(s) 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 also may expose the Fund to losses in excess of those amounts initially invested. Any costs associated with using derivatives will reduce the Fund&#x2019;s return.&lt;/span&gt;</rr:RiskTextBlock>

With respect to swap agreements, if the Index has a dramatic intraday move that causes a material decline in the Fund&#x2019;s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the transaction with the Fund.

CDS provide exposure to the credit of one or more debt issuers referred to as &#x201c;reference entities.&#x201d; These instruments are designed to reflect changes in credit quality, including events of default. CDS are most commonly discussed in terms of buying or selling credit protection with respect to a reference entity. Because the Fund seeks to provide long exposure to credit, it will generally be a net seller of credit protection with respect to North American high yield debt issuers. Selling credit protection is equivalent to being &#x201c;long&#x201d; credit. Index-based CDS provide credit exposure, through a single trade, to a basket of reference entities. A variety of high yield, index-based CDS with different characteristics are currently available in the marketplace with new issuances occurring periodically. Issuances typically vary in terms of underlying reference entities and maturity and, thus, can have significant differences in performance over time. The Fund intends to typically invest in new issuances of 5.25 year maturity North American high yield, index-based CDS, which are issued every six months on a 100-name basket, which names vary from issue to issue.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:-4.17%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:5pt;"&gt;U.S. Treasury Futures Contracts&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt; &#x2014; The Fund intends to invest in U.S. Treasury futures contracts in order to obtain interest rate exposure similar to the interest rate exposure &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;that is present in high yield bonds but is not present in &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;CDS. U.S. Treasury futures contracts are standardized contracts traded on, or subject to the rules of, an exchange that call for the future delivery of a specified quantity and type of U.S. Treasury at a specified time and place or, alternatively, may call for cash settlement. The Fund will generally purchase U.S. Treasury futures contracts as a substitute for a comparable market position in U.S. Treasury notes.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:-4.19%;"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Money Market Instruments&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014; The Fund expects that any cash balances maintained in connection with its use of derivatives will typically be held in high quality, short-term money market instruments, for example:&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;U.S. Treasury Bills&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014;&#160;U.S. government securities that have initial maturities of one year or less, and are supported by the full faith and credit of the U.S. government.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Repurchase Agreements&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt; &#x2014; Contracts in which a seller of securities, usually U.S. government securities or other money market instruments, agrees to buy the securities back at a specified time and price.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:-4.19%;"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;U.S. Treasury Obligations&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt; &#x2014; The Fund invests in obligations of the U.S. Department of the Treasury (&#x201c;U.S. Treasury&#x201d;), including Treasury bills and notes and other obligations issued or guaranteed by the U.S. Treasury, and repurchase agreements fully collateralized by U.S. Treasury securities.

High yield debt instruments may be more sensitive to economic changes, political changes, or adverse developments specific to a company than other fixed income instruments. These securities are subject to greater risk of loss, greater sensitivity to economic changes, valuation difficulties, and a potential lack of a secondary or public market for securities. High yield debt instruments are considered speculative with respect to the issuer&#x2019;s continuing ability to make principal and interest payments and, therefore, such instruments generally involve greater risk of default or price changes than higher rated debt instruments. Furthermore, the transaction costs associated &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;with the purchase and sale of high yield debt instruments may &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;vary greatly depending upon a number of factors and may adversely affect the Fund&#x2019;s performance.&lt;/span&gt;</rr:RiskTextBlock>

Upon the occurrence of a credit event, the Fund will have an obligation to pay the full notional value of a defaulted reference entity less recovery value. Recovery values for CDS are generally determined via an auction process to determine the final price for a given reference entity. Although the Fund intends, as practicable, to obtain initial exposure primarily through centrally cleared CDS, an active market may not exist for any of the CDS in which the Fund invests or in the reference entities subject to the CDS. As a result, the Fund&#x2019;s ability to maximize returns or minimize losses on such CDS may be impaired. Other risks of CDS include difficulty in valuation due to the lack of pricing transparency and the risk that changes in the value of the CDS do not reflect changes in the credit quality of the underlying reference entities or may otherwise perform differently than expected given market conditions.&lt;/span&gt;</rr:RiskTextBlock>

A wide variety of factors can cause interest rates to fluctuate (e.g., central bank monetary policies, inflation rates, general economic conditions, etc.). Commonly, investments subject to interest rate risk will decrease in value when interest rates rise and increase in value when interest rates decline. A rising interest rate environment may cause the value of debt instruments to decrease and adversely impact the liquidity of debt instruments. Without taking into account other factors, the value of securities with longer maturities typically fluctuates more in response to interest rate changes than securities with shorter maturities. These factors may cause the value of an investment in the Fund to change.&lt;/span&gt;</rr:RiskTextBlock>

These risks include counterparty risk and liquidity risk. When the Fund uses derivatives, there may be imperfect correlation between the value of the reference asset(s) 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 also may expose the Fund to losses in excess of those amounts initially invested.

The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -30% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -34.8%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

With respect to swap agreements, if the Index has a dramatic intraday move that causes a material decline in the Fund&#x2019;s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve its investment objective.&lt;/span&gt;</rr:RiskTextBlock>

This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual bank or on the sector as a whole cannot be predicted. The banks industry may also be affected by risks that affect the broader financial services industry. Additionally, in March 2023, the shut&#x2010;down of certain financial institutions raised economic concerns over disruption in the U.S. banking system. There can be no certainty that the actions taken by the U.S. government to strengthen public confidence in the U.S. banking system will be effective in mitigating the effects of financial institution failures on the economy and restoring public confidence in the U.S. banking system. Additional bank or financial institution failures may occur in the near term that may limit &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;access to short-term liquidity or have adverse impacts to &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;the economy.&lt;/span&gt;</rr:RiskTextBlock>

For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide inverse exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining inverse exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased. Conversely, if the Index has fallen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index falls.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -20% return on a yearly basis if the annual Index return were 20%. However, as the table shows, with a one-year Index return of 20% and an annualized Index volatility of 50%, the Fund could be expected to return -35.1%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9pt;font-weight:bold;"&gt;Estimated Fund Returns&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;font-weight:bold;"&gt;Index

Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued).

The use of leverage increases the risk of a total loss of your investment. If the Index approaches a 67% loss at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns. The cost of obtaining this leverage will lower your returns.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;on Fund returns. During periods of higher Index volatility, the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -30% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -34.8%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

Moreover, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may have exposure to the Index that is significantly greater or less than the Daily Target. Any of these factors may prevent the Fund from achieving exposure consistent with the Daily Target.&lt;/span&gt;</rr:RiskTextBlock>

The Fund may lose money if its derivatives do not perform as expected. To the extent to the Fund invests in swaps that use an ETF as the reference asset, the Fund may be subject to greater correlation risk since the performance of an ETF may not track the performance of the Index. Any costs associated with using derivatives will reduce the Fund&#x2019;s return.&lt;/span&gt;</rr:RiskTextBlock>

In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve its investment objective.&lt;/span&gt;</rr:RiskTextBlock>

The pharmaceuticals sector may also be affected by risks that affect the broader health care industry, including: heavy dependence on patent protection, with profitability affected by the expiration of patents; competitive forces that may make it difficult to raise prices and, in fact, may result in price discounts; and thin capitalization and limited product lines, markets and financial resources or personnel.&lt;/span&gt;</rr:RiskTextBlock>

The Index represents the communication services sector of the S&amp;amp;P 500 Index (&#x201c;S&amp;amp;P 500&#x201d;). The Index is one of eleven (11) of the S&amp;amp;P Select Sector Indices (the &#x201c;Select Sector Indices&#x201d;), each designed to measure the performance of a sector of the S&amp;amp;P 500. Membership in the Select Sector Indices is generally determined by the Global Industry Classification Standard (&#x201c;GICS&#x201d;), which classifies securities primarily based on revenues; however, earnings and market perception are also considered. The Index includes equity securities of companies from the following industries: diversified telecommunications services; wireless telecommunications services; media; entertainment; and interactive media &amp;amp; services. The Index is sponsored by Standard &amp;amp; Poor&#x2019;s (the &#x201c;Index Provider&#x201d;), which is not affiliated with the Fund or ProFund Advisors. The Index Provider determines the composition of the Index and relative weightings of the Index constituents, and publishes information regarding the market value of the Index.

However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

The use of leverage increases the risk of a total loss of your investment. If the Index approaches a 67% loss at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns.

During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -30% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -34.8%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

The Index is one of eleven S&amp;amp;P Select Sector Indices (the &#x201c;Select Sector Indices&#x201d;), each designed to measure the performance of a sector of the S&amp;amp;P 500. Sectors are assigned using the Global Industry Classification Standard (&#x201c;GICS&#x201d;), which classifies securities primarily based on revenues. The Index includes equity securities of companies from the following GICS industries: automobile components; automobiles; household durables; leisure products; textiles, apparel &amp;amp; luxury goods; hotels, restaurants, &amp;amp; leisure; diversified consumer services; distributors; broadline retail; and specialty retail.

For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

The use of leverage increases the risk of a total loss of your investment. If the Index approaches a 67% loss at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns. The cost of obtaining this leverage will lower your returns.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -30% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -34.8%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

Fees, expenses, transaction costs, financing costs associated with the use of derivatives, among other factors, will adversely impact the Fund&#x2019;s ability to meet its Daily Target. In addition, the Fund may not have leveraged exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index. Moreover, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may have exposure to the Index that is significantly greater or less than the Daily Target. Any of these factors may prevent the Fund from achieving exposure consistent with the Daily Target.&lt;/span&gt;</rr:RiskTextBlock>

For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

The use of leverage increases the risk of a total loss of your investment. If the Index approaches a 67% loss at any point in the day, you could lose your entire &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;investment. As a result, an investment in the Fund may not be &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;suitable for all investors. The use of leverage increases the volatility of your returns. The cost of obtaining this leverage will lower your returns.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -30% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -34.8%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

The use of leverage increases the risk of a total loss of your investment. If the Index approaches a 67% loss at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns. The cost of obtaining this leverage will lower your returns.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -30% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -34.8%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

Fees, expenses, transaction costs, financing costs associated with the use of derivatives, among other factors, will adversely impact the Fund&#x2019;s ability to meet its Daily Target. In addition, the Fund may not have leveraged exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index. Moreover, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may have exposure to the Index that is significantly greater or less than the Daily Target. Any of these factors may prevent the Fund from achieving exposure consistent with the Daily Target.&lt;/span&gt;</rr:RiskTextBlock>

The Fund may lose money if its derivatives do not perform as expected. To the extent to the Fund invests in swaps that use an ETF as the reference asset, the Fund may be subject to greater correlation risk since the performance of an ETF may not track the performance of the Index. Any costs associated with using derivatives will reduce the Fund&#x2019;s return.&lt;/span&gt;</rr:RiskTextBlock>

In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve its investment objective.&lt;/span&gt;</rr:RiskTextBlock>

The energy industry has recently experienced significant volatility due to dramatic changes in the prices of energy commodities, and it is possible that such volatility will continue in the future.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;On February 24, 2022, Russia commenced a military attack &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;on Ukraine.

The European financial markets have experienced significant volatility and several European countries have been adversely affected by unemployment, budget deficits and economic downturns. In addition, several European countries (including the United Kingdom) have experienced credit rating downgrades, rising government debt levels and, for certain European countries (including Spain, Portugal, Ireland and Italy), weaknesses in sovereign debt. These events, along with decreasing imports or exports, changes in governmental or EU regulations on trade, the default or threat of default by a European country on its sovereign debt, an economic recession in a European country, or the threat of a European country to leave the EU may have a significant adverse effect on the affected European country, issuers in the affected European country, the economies of other European countries, or their trading partners. Such events, or even the threat of these events, may cause the value of securities issued by issuers in such European countries to fall, in some cases drastically. These events may also cause further volatility in the European financial markets. To the extent that the Fund&#x2019;s assets are exposed to investments from issuers in European countries or denominated in euro, their trading partners, or other European countries, these events may negatively impact the performance of the Fund.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;On February 24, 2022, Russia commenced a military attack &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;on Ukraine. The military incursion has led to, and may lead to additional sanctions being levied by the United States, European Union, United Kingdom and other countries against Russia. Russia&#x2019;s military incursion and the resulting sanctions and other rapidly evolving measures in response could adversely affect global energy and financial markets and thus could affect the value of the Fund&#x2019;s investments. The severity, extent and duration of the military conflict, sanctions and resulting market disruptions are impossible to predict, but could have a material adverse effect on the European region and beyond, including significant negative impacts on the economy and the markets for certain securities and commodities, such as oil and natural gas. How long such tensions and related events will last cannot be predicted. These tensions and any related events could have significant impact on the Fund&#x2019;s performance and the value of an investment in the Fund.&lt;/span&gt;</rr:RiskTextBlock>

The Index measures the value of the U.S. Dollar against a basket of currencies of the top six trading partners of the United States, as measured in 1973 (the &#x201c;Benchmark&#x201d;). These currencies and their weightings as of July 31, 2023 are: euro 57.6%; Japanese yen 13.6%; British pound 11.9%; Canadian dollar 9.1%; Swedish krona 4.2% and Swiss franc 3.6%. The Fund is designed to benefit from a decline in the value of the U.S. Dollar against the value of the currencies included in the Benchmark. Accordingly, as the value of the U.S. Dollar depreciates (i.e., &#x201c;falls&#x201d;) versus the Benchmark, the performance of the Fund generally should be expected to increase. As the value of the U.S. Dollar appreciates versus the Benchmark, the performance of the Fund generally should be expected to decline.&lt;/span&gt;</rr:ObjectivePrimaryTextBlock>

The Index represents the financials sector of the S&amp;amp;P 500 Index (&#x201c;S&amp;amp;P 500&#x201d;). The Index is one of eleven S&amp;amp;P Select Sector Indices (the &#x201c;Select Sector Indices&#x201d;), each designed to measure the performance of a sector of the S&amp;amp;P 500. Sectors are assigned using the Global Industry Classification Standard (&#x201c;GICS&#x201d;), which classifies securities primarily based on revenues. The Index includes equity securities of companies from the following GICS industries: banks; financial services; consumer finance; capital markets; mortgage real estate investment trusts (REITS); and insurance.

For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -30% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -34.8%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

In addition, the Fund may not have leveraged exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index.

For example, two parties &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;may agree to exchange the return (or differentials in &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;rates of returns) earned or realized on a particular investment or instrument.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:-4.19%;"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Money Market Instruments&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014; The Fund expects that any cash balances maintained in connection with its use of derivatives will typically be held in high quality, short-term money market instruments, for example:&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;U.S. Treasury Bills&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014;&#160;U.S. government securities that have initial maturities of one year or less, and are supported by the full faith and credit of the U.S. government.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Repurchase Agreements&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt; &#x2014; Contracts in which a seller of securities, usually U.S. government securities or other money market instruments, agrees to buy the securities back at a specified time and price.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;ProFund Advisors uses a mathematical approach to investing in &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;which it determines the type, quantity and mix of investment positions that it believes, in combination, the Fund should hold to produce daily returns consistent with the Daily Target. For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

The use of leverage increases the risk of a total loss of your investment. If the Index approaches a 67% loss at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;volatility of your returns. The cost of obtaining this leverage &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;will lower your returns.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -30% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -34.8%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

The Fund may lose money if its derivatives do not perform as expected. To the extent to the Fund invests in swaps that use an ETF as the reference asset, the Fund may be subject to greater correlation risk since the performance of an ETF may not track the performance of the Index. Any costs associated with using derivatives will reduce the Fund&#x2019;s return.&lt;/span&gt;</rr:RiskTextBlock>

However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns.

During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -30% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -34.8%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -30% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -34.8%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

The Fund may lose money if its derivatives do not perform as expected. To the extent to the Fund invests in swaps that use an ETF as the reference asset, the Fund may be subject to greater correlation risk since the performance of an ETF may not track the performance of the Index. Any costs associated with using derivatives will reduce the Fund&#x2019;s return.&lt;/span&gt;</rr:RiskTextBlock>

For example, large-cap companies may be unable to respond quickly to new competitive challenges, such as changes in technology, and also may not be able to attain the high growth rate of successful smaller companies.&lt;/span&gt;</rr:RiskTextBlock>

The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -30% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -34.8%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve its investment objective.&lt;/span&gt;</rr:RiskTextBlock>

Mid-cap companies may have limited product lines or resources, may be dependent upon a particular market niche and may have greater fluctuations in price than the stocks of larger companies. Mid-cap companies may lack the financial and personnel resources to handle economic or industry-wide setbacks and, as a result, such setbacks could have a greater effect on mid-cap security prices. Additionally, mid-cap company stocks may trade at greater spreads or lower trading volumes, and may be less liquid than the stocks of larger companies. Further, stocks of mid-sized companies could be more difficult to liquidate during market downturns compared to larger, more widely traded companies.&lt;/span&gt;</rr:RiskTextBlock>

For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

The use of leverage increases the risk of a total loss of your investment. If the Index approaches a 67% loss at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns. The cost of obtaining this leverage will lower your returns.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:0.00%;"&gt;Index moves up and down from day-to-day) on your &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -30% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -34.8%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

Fees, expenses, transaction costs, financing costs associated with the use of derivatives, among other factors, will adversely impact the Fund&#x2019;s ability to meet its Daily Target. In addition, the Fund may not have leveraged exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index. Moreover, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may have exposure to the Index that is significantly greater or less than the Daily Target. Any of these factors may prevent the Fund from achieving exposure consistent with the Daily Target.&lt;/span&gt;</rr:RiskTextBlock>

The Fund may lose money if its derivatives do not perform as expected. To the extent to the Fund invests in swaps that use an ETF as the reference asset, the Fund may be subject to greater correlation risk since the performance of an ETF may not track the performance of the Index. Any costs associated with using derivatives will reduce the Fund&#x2019;s return.&lt;/span&gt;</rr:RiskTextBlock>

With respect to swap agreements, if the Index has a dramatic intraday move that causes a material decline in the Fund&#x2019;s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve its investment objective.&lt;/span&gt;</rr:RiskTextBlock>

The energy industry has recently experienced significant volatility due to dramatic changes in the prices of energy commodities, and it is possible that such volatility will continue in the future.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;On February 24, 2022, Russia commenced a military attack &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;on Ukraine. The outbreak of hostilities between the two &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;countries could result in more widespread conflict and could &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;have a severe adverse effect on the region and the markets for securities and commodities, including oil. In addition, sanctions imposed on Russia by the United States and other countries, and any sanctions imposed in the future could have a significant adverse impact on the Russian economy and related markets. How long such conflict and related events will last and whether it will escalate further cannot be predicted. Impacts from the conflict and related events could have significant impact on the Fund&#x2019;s performance, and the value of an investment in the Fund may decline significantly.&lt;/span&gt;</rr:RiskTextBlock>

However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued).

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -30% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -34.8%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

For example, two parties &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;may agree to exchange the return (or differentials in rates of returns) earned or realized on a particular investment or instrument.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:-4.19%;"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Money Market Instruments&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014; The Fund expects that any cash balances maintained in connection with its use of derivatives will typically be held in high quality, short-term money market instruments, for example:&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;U.S. Treasury Bills&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014;&#160;U.S. government securities that have initial maturities of one year or less, and are supported by the full faith and credit of the U.S. government.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Repurchase Agreements&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt; &#x2014; Contracts in which a seller of securities, usually U.S. government securities or other money market instruments, agrees to buy the securities back at a specified time and price.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;ProFund Advisors uses a mathematical approach to investing in &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;which it determines the type, quantity and mix of investment positions that it believes, in combination, the Fund should hold to produce daily returns consistent with the Daily Target. For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

The use of leverage increases the risk of a total loss of your investment. If the Index approaches a 67% loss at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;volatility of your returns. The cost of obtaining this leverage &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;will lower your returns.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -30% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -34.8%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

The use of leverage increases the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;risk of a total loss of your investment. If the Index approaches a 67% loss at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns. The cost of obtaining this leverage will lower your returns.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -30% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -34.8%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

The Fund may lose money if its derivatives do not perform as expected. To the extent to the Fund invests in swaps that use an ETF as the reference asset, the Fund may be subject to greater correlation risk since the performance of an ETF may not track the performance of the Index. Any costs associated with using derivatives will reduce the Fund&#x2019;s return.&lt;/span&gt;</rr:RiskTextBlock>

In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve its investment objective.&lt;/span&gt;</rr:RiskTextBlock>

Although interest rates have significantly increased since 2022, the prices of real estate-related assets generally have not decreased as much as may be expected based on historical correlations between interest rates and prices of real estate-related assets. This presents an increased risk of a correction or severe downturn in real estate-related asset prices, which could adversely impact the value of other investments as well (such as loans, securitized debt and other fixed income securities). This risk is particularly present with respect to commercial real estate-related asset prices, and the value of other investments with a connection to the commercial real estate sector. As examples of the current risks faced by real estate-related assets: tenant vacancy rates, tenant turnover and tenant concentration have increased; owners of real estate have faced headwinds, delinquencies and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;difficulties in collecting rents and other payments (which &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;increases the risk of owners being unable to pay or otherwise defaulting on their own borrowings and obligations); property values have declined; inflation, upkeep costs and other expenses have increased; and rents have declined for many properties. The economic impacts of COVID-19 have created a unique challenge for real estate markets. Many businesses have either partially or fully transitioned to a remote-working environment and this transition may negatively impact the occupancy rates of commercial real estate over time. Similarly, trends in favor of online shopping may negatively affect the real estate market for commercial properties.&lt;/span&gt;</rr:RiskTextBlock>

The Long Bond&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Long Bond has risen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased. Conversely, if the Long Bond has fallen on a given day, net assets of the Fund should rise (assuming there were no share redemptions).

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Long Bond returns and Long Bond volatility (how much the value of the Long Bond moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Long Bond volatility has a negative impact on Fund returns. During periods of higher Long Bond volatility, the Long Bond volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Long Bond.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Long Bond &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;volatility and Long Bond return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:0.00%;"&gt;consider monitoring your investments in the Fund in light &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Long Bond gains or losses and higher Long Bond volatility. Your return will tend to be better than the Daily Target when there are larger Long Bond gains or losses and lower Long Bond volatility. You may lose money when the Long Bond return is flat (i.e., close to zero) and you may lose money when the Long Bond falls.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Long Bond volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Long Bond returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Long Bond return for a one-year period. Each column corresponds to a level of hypothetical annualized Long Bond volatility. For example, the Fund may mistakenly be expected to achieve a -25% return on a yearly basis if the annual Long Bond return were 20%. However, as the table shows, with a one-year Long Bond return of 20% and an annualized Long Bond volatility of 50%, the Fund could be expected to return -44%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Long Bond; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain inverse leveraged exposure) of zero percent. If &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

Fees, expenses, transaction costs, financing costs associated with the use of derivatives, among other factors, will adversely impact the Fund&#x2019;s ability to meet its Daily Target. In addition, the Fund may not have inverse leveraged exposure to all of the securities in the Long Bond, its weighting of securities may be different from that of the Long Bond, and it may invest in instruments not included in the Long Bond. Moreover, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may have exposure to the Long Bond that is significantly greater or less than the Daily Target. Any of these factors may prevent the Fund from achieving exposure consistent with the Daily Target.&lt;/span&gt;</rr:RiskTextBlock>

A wide variety of factors can cause interest rates to fluctuate (e.g., central bank monetary policies, inflation rates, general economic conditions, etc.). Commonly, investments subject to interest rate risk will decrease in value when interest rates rise and increase in value when interest rates decline. A rising interest rate environment may cause the value of debt instruments to decrease and adversely impact the liquidity of debt instruments. Without taking into account other factors, the value of securities with longer maturities typically fluctuates more in response to interest rate changes than securities with shorter maturities. These factors may cause the value of an investment in the Fund to change. As a fund seeking daily investment results, before fees and expenses, that correspond to one and one-quarter times the inverse (-1.25x) of the daily return of the Long Bond, the Fund&#x2019;s performance will generally be more favorable when interest rates rise and less favorable when interest rates decline.&lt;/span&gt;</rr:RiskTextBlock>

For example, two parties may agree to exchange the return (or differentials in rates of returns) earned or realized on a particular investment or instrument.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Futures Contracts&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014;&#160;Standardized contracts that obligate the parties to buy or sell an asset at a predetermined price and date in the future.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:-4.19%;"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Money Market Instruments&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014; The Fund expects that any cash balances maintained in connection with its use of derivatives will typically be held in high quality, short-term money market instruments, for example:&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;U.S. Treasury Bills&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014;&#160;U.S. government securities that have initial maturities of one year or less, and are supported by the full faith and credit of the U.S. government.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Repurchase Agreements&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt; &#x2014; Contracts in which a seller of securities, usually U.S. government securities or other money market instruments, agrees to buy the securities back at a specified time and price.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;ProFund Advisors uses a mathematical approach to investing in &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;which it determines the type, quantity and mix of investment positions that it believes, in combination, the Fund should hold to produce daily returns consistent with the Daily Target. For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide inverse exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Note or to securities not contained in the Note or in financial instruments, with the intent of obtaining inverse exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Note is consistent with the Daily Target. The Note&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Note has risen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased. Conversely, if the Note has fallen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

Obtaining inverse or &#x201c;short&#x201d; exposure may be considered an aggressive investment technique. The costs of obtaining this short exposure will lower your returns. If the level of the Note approaches a 100% increase at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Note returns and Note volatility (how much the value of the Note moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Note volatility has a negative impact on Fund returns. During periods of higher Note volatility, the Note volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Note.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Note volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Note return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Note gains or losses and higher Note volatility. Your return will tend to be better than the Daily Target when there are larger Note gains or losses and lower Note volatility. You may lose money when the Note return is flat (i.e., close to zero) and you may lose money when the Note falls.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Note volatility and Note &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Note return for a one-year period. Each column corresponds to a level of hypothetical annualized Note volatility. For example, the Fund may mistakenly be expected to achieve a -20% return on a yearly basis if the annual Note return were 20%. However, as the table shows, with a one-year Note return of 20% and an annualized Note volatility of 50%, the Fund could be expected to return -35.1%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9pt;font-weight:bold;"&gt;Estimated Fund Returns&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;font-weight:bold;"&gt;Note

A wide variety of factors can cause interest rates to fluctuate (e.g., central bank monetary policies, inflation rates, general economic conditions, etc.). Commonly, investments subject to interest rate risk will decrease in value when interest rates rise and increase in value when interest rates decline. A rising interest rate environment may cause the value of debt instruments to decrease and adversely impact the liquidity of debt instruments. Without taking into account other factors, the value of securities with longer maturities typically fluctuates more in response to interest rate changes than securities with shorter maturities. These factors may cause the value of an investment in the Fund to change. As a fund seeking daily investment results, before fees and expenses, that correspond to the inverse (-1x) of the daily return of the Note, the Fund&#x2019;s performance will generally be more favorable when interest rates rise and less favorable when interest rates decline.&lt;/span&gt;</rr:RiskTextBlock>

The Benchmark&#x2019;s currencies and their weightings as of July 31, 2023 are: euro 57.6%; Japanese yen 13.6%; British pound 11.9%; Canadian dollar 9.1%; Swedish krona 4.2% and Swiss franc 3.6%. The Fund is designed to benefit from an increase in the value of the U.S. Dollar against the value of the currencies included in the Benchmark. Accordingly, as the value of the U.S. Dollar appreciates (i.e., rises) versus the Benchmark, the performance of the Fund generally should be expected to increase. As the value of the U.S. Dollar depreciates versus the Benchmark, the performance of the Fund generally should be expected to decline.&lt;/span&gt;</rr:ObjectivePrimaryTextBlock>

However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining inverse exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased. Conversely, if the Index has fallen on a given day, net assets of the Fund should rise (assuming there were no share redemptions).

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:0.00%;"&gt;returns and Index volatility (how much the value of the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index falls.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -20% return on a yearly basis if the annual Index return were 20%.

For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

The use of leverage increases the risk of a total loss of your investment. If the Index approaches a 67% loss at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns. The cost of obtaining this leverage will lower your returns.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:0.00%;"&gt;holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -30% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -34.8%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

Fees, expenses, transaction costs, financing costs associated with the use of derivatives, among other factors, will adversely impact the Fund&#x2019;s ability to meet its Daily Target. In addition, the Fund may not have leveraged exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index. Moreover, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may have exposure to the Index that is significantly greater or less than the Daily Target. Any of these factors may prevent the Fund from achieving exposure consistent with the Daily Target.&lt;/span&gt;</rr:RiskTextBlock>

The Fund may lose money if its derivatives do not perform as expected. To the extent to the Fund invests in swaps that use an ETF as the reference asset, the Fund may be subject to greater correlation risk since the performance of an ETF may not track the performance of the Index. Any costs associated with using derivatives will reduce the Fund&#x2019;s return.&lt;/span&gt;</rr:RiskTextBlock>

The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased. Conversely, if the Index has fallen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index falls.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -20% return on a yearly basis if the annual Index return were 20%. However, as the table shows, with a one-year Index return of 20% and an annualized Index volatility of 50%, the Fund could be expected to return -35.1%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9pt;font-weight:bold;"&gt;Estimated Fund Returns&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;font-weight:bold;"&gt;Index

In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve its investment objective.&lt;/span&gt;</rr:RiskTextBlock>

The energy industry has recently experienced significant volatility due to dramatic changes in the prices of energy commodities, and it is possible that such volatility will continue in the future.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;On February 24, 2022, Russia commenced a military attack &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;on Ukraine. The outbreak of hostilities between the two countries could result in more widespread conflict and could have a severe adverse effect on the region and the markets for securities and commodities, including oil. In addition, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;sanctions imposed on Russia by the United States and other &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;countries, and any sanctions imposed in the future could have a significant adverse impact on the Russian economy and related markets. How long such conflict and related events will last and whether it will escalate further cannot be predicted. Impacts from the conflict and related events could have significant impact on the Fund&#x2019;s performance, and the value of an investment in the Fund may decline significantly.&lt;/span&gt;</rr:RiskTextBlock>

However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining inverse exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased. Conversely, if the Index has fallen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index falls.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -20% return on a yearly basis if the annual Index return were 20%. However, as the table shows, with a one-year Index return of 20% and an annualized Index volatility of 50%, the Fund could be expected to return -35.1%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9pt;font-weight:bold;"&gt;Estimated Fund Returns&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;font-weight:bold;"&gt;Index

For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide inverse exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining inverse exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased. Conversely, if the Index has fallen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

Obtaining inverse or &#x201c;short&#x201d; exposure may be considered an aggressive investment technique. The costs of obtaining this short exposure will lower your returns. If the level of the Index approaches a 100% increase at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index falls.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -20% return on a yearly basis if the annual Index return were 20%. However, as the table shows, with a one-year Index return of 20% and an annualized Index volatility of 50%, the Fund could be expected to return -35.1%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9pt;font-weight:bold;"&gt;Estimated Fund Returns&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;font-weight:bold;"&gt;Index

The Index is one of eleven S&amp;amp;P Select Sector Indices (the &#x201c;Select Sector Indices&#x201d;), each designed to measure the performance of a sector of the S&amp;amp;P 500. Sectors are assigned using the Global Industry Classification Standard (&#x201c;GICS&#x201d;), which classifies securities primarily based on revenues. The Index includes equity securities of companies from the following GICS industries: diversified REITs; industrial REITs; hotel &amp;amp; resort REITs; office REITs; heath care REITs; residential REITs; retail REITs; specialized REITs; and real estate management &amp;amp; development.

The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased. Conversely, if the Index has fallen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index falls.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -20% return on a yearly basis if the annual Index return were 20%. However, as the table shows, with a one-year Index return of 20% and an annualized Index volatility of 50%, the Fund could be expected to return -35.1%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9pt;font-weight:bold;"&gt;Estimated Fund Returns&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;font-weight:bold;"&gt;Index

Although interest rates have significantly increased since 2022, the prices of real estate-related assets generally have not decreased as much as may be expected based on historical correlations between interest rates and prices of real estate-related assets. This presents an increased &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;risk of a correction or severe downturn in real estate-related &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;asset prices, which could adversely impact the value of other investments as well (such as loans, securitized debt and other fixed income securities). This risk is particularly present with respect to commercial real estate-related asset prices, and the value of other investments with a connection to the commercial real estate sector. As examples of the current risks faced by real estate-related assets: tenant vacancy rates, tenant turnover and tenant concentration have increased; owners of real estate have faced headwinds, delinquencies and difficulties in collecting rents and other payments (which increases the risk of owners being unable to pay or otherwise defaulting on their own borrowings and obligations); property values have declined; inflation, upkeep costs and other expenses have increased; and rents have declined for many properties. The economic impacts of COVID-19 have created a unique challenge for real estate markets. Many businesses have either partially or fully transitioned to a remote-working environment and this transition may negatively impact the occupancy rates of commercial real estate over time. Similarly, trends in favor of online shopping may negatively affect the real estate market for commercial properties.&lt;/span&gt;</rr:RiskTextBlock>

However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining inverse exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased. Conversely, if the Index has fallen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index falls.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -20% return on a yearly basis if the annual Index return were 20%. However, as the table shows, with a one-year Index return of 20% and an annualized Index volatility of 50%, the Fund could be expected to return -35.1%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9pt;font-weight:bold;"&gt;Estimated Fund Returns&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;font-weight:bold;"&gt;Index

Small-cap companies may lack the financial and personnel resources to handle economic or industry-wide setbacks and, as a result, such setbacks could have a greater effect on small-cap security prices. Additionally, small-cap company stocks may trade at greater spreads or lower trading volumes, and may be less liquid than the stocks of larger companies.

The Fund may lose money if its derivatives do not perform as expected. To the extent to the Fund invests in swaps that use an ETF as the reference asset, the Fund may be subject to greater correlation risk since the performance of an ETF may not track the performance of the Index. Any costs associated with using derivatives will reduce the Fund&#x2019;s return.&lt;/span&gt;</rr:RiskTextBlock>

Additionally, small-cap company stocks may trade at greater spreads or lower trading volumes, and may be less liquid than the stocks of larger companies. Further, stocks of small-sized companies could be more difficult to liquidate during market downturns compared to larger, more widely traded companies.&lt;/span&gt;</rr:RiskTextBlock>

Small-cap companies may have limited product lines or resources, may be dependent upon a particular market niche and may have greater fluctuations in price than the stocks of larger companies. Small-cap companies may lack the financial and personnel resources to handle economic or industry-wide setbacks and, as a result, such setbacks could have a greater effect on small-cap security prices. Additionally, small-cap company stocks may trade at greater spreads or lower trading volumes, and may be less liquid than the stocks of larger companies. Further, stocks of small-sized companies could be more difficult to liquidate during market downturns compared to larger, more widely traded companies.&lt;/span&gt;</rr:RiskTextBlock>

The Fund may lose money if its derivatives do not perform as expected. To the extent to the Fund invests in swaps that use an ETF as the reference asset, the Fund may be subject to greater correlation risk since the performance of an ETF may not track the performance of the Index. Any costs associated with using derivatives will reduce the Fund&#x2019;s return.&lt;/span&gt;</rr:RiskTextBlock>

With respect to swap agreements, if the Index has a dramatic intraday move that causes a material decline in the Fund&#x2019;s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve its investment objective.&lt;/span&gt;</rr:RiskTextBlock>

Small-cap companies may lack the financial and personnel resources to handle economic or industry-wide setbacks and, as a result, such setbacks could have a greater effect on small-cap security prices. Additionally, small-cap company stocks may trade at greater spreads or lower trading volumes, and may be less liquid than the stocks of larger companies. Further, stocks of small-sized companies could be more difficult to liquidate during market downturns compared to larger, more widely traded companies.&lt;/span&gt;</rr:RiskTextBlock>

The Index is one of eleven S&amp;amp;P Select Sector Indices (the &#x201c;Select Sector Indices&#x201d;), each designed to measure the performance of a sector of the S&amp;amp;P 500. Sectors are assigned using the Global Industry Classification Standard (&#x201c;GICS&#x201d;), which classifies securities primarily based on revenues. The Index includes equity securities of companies from the following GICS industries: IT services; software; communications equipment; technology, hardware, storage &amp;amp; peripherals; electronic equipment, instruments, &amp;amp; components; and semiconductors &amp;amp; semiconductor equipment. The Index constituents are weighted using a capped modified market capitalization methodology and rebalanced quarterly.

For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -30% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -34.8%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

It is a market capitalization-weighted index of 500 U.S. operating companies and real estate investment trusts selected through a process that factors in criteria such as liquidity, price, market capitalization, financial viability and public float.

In a standard swap transaction, two parties agree to exchange or &#x201c;swap&#x201d; payments based on the change in value of an underlying asset or benchmark. For example, two parties may agree to exchange the return (or differentials in rates of returns) earned or realized on a particular investment or instrument.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Futures Contracts&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014;&#160;Standardized contracts that obligate the parties to buy or sell an asset at a predetermined price and date in the future.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:-4.19%;"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Money Market Instruments&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014; The Fund expects that any cash balances maintained in connection with its use of derivatives will typically be held in high quality, short-term money market instruments, for example:&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;U.S. Treasury Bills&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014;&#160;U.S. government securities that have initial maturities of one year or less, and are supported by the full faith and credit of the U.S. government.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Repurchase Agreements&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt; &#x2014; Contracts in which a seller of securities, usually U.S. government securities or other money market instruments, agrees to buy the securities back at a specified time and price.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;ProFund Advisors uses a mathematical approach to investing in &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;which it determines the type, quantity and mix of investment positions that it believes, in combination, the Fund should hold to produce daily returns consistent with the Daily Target. For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide inverse leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining inverse leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased. Conversely, if the Index has fallen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

The use of leverage increases the risk of a total loss of your investment. If the Index approaches a 50% gain at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns.

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index falls.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;expected to achieve a -40% return on a yearly basis if the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;annual Index return were 20%. However, as the table shows, with a one-year Index return of 20% and an annualized Index volatility of 50%, the Fund could be expected to return -67.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain inverse leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

Fees, expenses, transaction costs, financing costs associated with the use of derivatives, among other factors, will adversely impact the Fund&#x2019;s ability to meet its Daily Target. In addition, the Fund may not have inverse leveraged exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index. Moreover, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;have exposure to the Index that is significantly greater or less &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;than the Daily Target.

The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;there were no share redemptions). As a result, the Fund&#x2019;s &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be.

As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility.

Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;expected to achieve a -40% return on a yearly basis if the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -50.2%.&lt;/span&gt;&lt;span

For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

The use of leverage increases the risk of a total loss of your investment. If the Index approaches a 50% loss at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns. The cost of obtaining this leverage will lower your returns.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -40% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -50.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9pt;font-weight:bold;"&gt;Estimated Fund Returns&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;font-weight:bold;"&gt;Index

Changes in Chinese government policy and economic growth rates could significantly affect local markets and the entire Greater China region. China has yet to develop comprehensive securities, corporate, or commercial laws, and its economy is experiencing a relative slowdown. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Internal social unrest or confrontations with neighboring countries may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations, and higher rates of inflation. Investments in securities of Chinese companies are subject to China&#x2019;s heavy dependence on exports. Reductions in spending on Chinese products and services, institution of tariffs or other trade barriers, including as a result of heightened trade tensions between China and the United States, or a downturn in any of the economies of China&#x2019;s key trading partners may have an adverse impact on the Chinese economy and the values of Chinese companies. Significant portions of the Chinese securities markets may become rapidly illiquid, as Chinese issuers have the ability to suspend the trading of their equity securities and have shown a willingness to exercise that option in response to market volatility and other events. The liquidity of Chinese securities may shrink or disappear suddenly and without warning as a result of adverse economic, market or political events, or adverse investor perceptions, whether or not accurate.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;Investments in issuers in China may include investments &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;through legal structures known as VIEs. In China, ownership of companies in certain sectors by foreign individuals and entities (including U.S. persons and entities such as a Fund) is prohibited. In order to facilitate foreign investment in these businesses, many Chinese companies have created VIEs. In these arrangements, a China-based operating company typically establishes an offshore shell company in another jurisdiction, such as the Cayman Islands. That shell company enters into service and other contracts with the China-based operating company, then issues shares on a foreign exchange, such as the New York Stock Exchange. Foreign investors hold stock in the shell company (i.e., the U.S.-listed company) rather than directly in the China-based operating company. This arrangement allows U.S. investors to obtain economic exposure to the China-based company through contractual means rather than through formal equity ownership. Intervention by the Chinese government with respect to VIEs could significantly affect the Chinese operating company&#x2019;s performance (and, in turn, the Fund&#x2019;s performance) and undermine the enforceability of the VIE structure.&lt;/span&gt;</rr:RiskTextBlock>

For example, two parties may agree to exchange the return (or differentials in rates of returns) earned or realized on a particular investment or instrument.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Futures Contracts&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014;&#160;Standardized contracts that obligate the parties to buy or sell an asset at a predetermined price and date in the future.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:-4.19%;"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Money Market Instruments&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014; The Fund expects that any cash balances maintained in connection with its use of derivatives will typically be held in high quality, short-term money market instruments, for example:&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;U.S. Treasury Bills&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014;&#160;U.S. government securities that have initial maturities of one year or less, and are supported by the full faith and credit of the U.S. government.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Repurchase Agreements&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt; &#x2014; Contracts in which a seller of securities, usually U.S. government securities or other money market instruments, agrees to buy the securities back at a specified time and price.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;ProFund Advisors uses a mathematical approach to investing in &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;which it determines the type, quantity and mix of investment positions that it believes, in combination, the Fund should hold to produce daily returns consistent with the Daily Target. For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;invest in or gain exposure to only a representative sample of the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

The use of leverage increases the risk of a total loss of your investment. If the Index approaches a 50% loss at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns. The cost of obtaining this leverage will lower your returns.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;the Index return is flat (i.e., close to zero) and you may lose &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -40% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -50.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9pt;font-weight:bold;"&gt;Estimated Fund Returns&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;font-weight:bold;"&gt;Index

However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;exposure will need to be increased. Conversely, if the Index has &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued).

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be.

As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;expected to achieve a -40% return on a yearly basis if the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -50.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9pt;font-weight:bold;"&gt;Estimated Fund Returns&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;font-weight:bold;"&gt;Index

Because of differences in settlement times and/or foreign market holidays, transactions in a foreign market may take place one or more days after the necessary exposure to these investments is determined.&lt;/span&gt;</rr:RiskTextBlock>

The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued).

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -40% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -50.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9pt;font-weight:bold;"&gt;Estimated Fund Returns&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;font-weight:bold;"&gt;Index

This is due primarily to the time difference in determining the level of the Index (11:30 a.m., Eastern Time) and valuation of the Fund (4:00 p.m., Eastern Time). As such, correlation to the Index will generally be measured by comparing the daily change in the Fund&#x2019;s NAV per share to the performance of one or more U.S. exchange-traded securities or financial instruments that reflect the values of the securities underlying the Index as of the Fund&#x2019;s NAV calculation time. In addition, in certain cases, the Fund&#x2019;s portfolio investments trade in markets on days and at times when the Fund is not open for business. As a result, the value of the Fund may change, perhaps significantly, on days and at times when shareholders are unable to purchase, redeem, or exchange shares.&lt;/span&gt;</rr:RiskTextBlock>

Fees, expenses, transaction costs, financing costs associated with the use of derivatives, among other factors, will adversely impact the Fund&#x2019;s ability to meet its Daily Target. In addition, the Fund may not have leveraged exposure to all of the securities in the Index, its weighting of &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;securities may be different from that of the Index, and it may &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;invest in instruments not included in the Index. Moreover, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may have exposure to the Index that is significantly greater or less than the Daily Target. Any of these factors may prevent the Fund from achieving exposure consistent with the Daily Target. Also, the Fund will measure its correlation to the performance of one or more ETFs. It is important to note that correlation to these ETFs may vary from the correlation to the Index due to embedded costs and other factors.&lt;/span&gt;</rr:RiskTextBlock>

In addition, markets for foreign investments are usually less liquid, more volatile and significantly smaller than markets for U.S. securities, which may affect, among other things, the Fund&#x2019;s ability to purchase or sell foreign investments at appropriate times and prices. Because of differences in settlement times and/or foreign market holidays, transactions in a foreign market may take place one or more days after the necessary exposure to these investments is determined.&lt;/span&gt;</rr:RiskTextBlock>

As of July 31, 2023, the Index had a significant portion of its value in issuers in the&#160;financials and industrials industry groups.&lt;/span&gt;</rr:RiskTextBlock>

However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

The use of leverage increases the risk of a total loss of your investment. If the Index approaches a 50% loss at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns. The cost of obtaining this leverage will lower your returns.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:0.00%;"&gt;important that you understand the impact of Index &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -40% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -50.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9pt;font-weight:bold;"&gt;Estimated Fund Returns&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;font-weight:bold;"&gt;Index

This is due primarily to the time difference in determining the level of the Index (3:00 p.m., Japan Standard Time) and valuation of the Fund (4:00 p.m., Eastern Time). As such, correlation to the Index will generally be measured by comparing the daily change in the Fund&#x2019;s NAV per share to the performance of one or more U.S. exchange-traded securities or financial instruments that reflect the values of the securities underlying the Index as of the Fund&#x2019;s NAV calculation time. In addition, in certain cases, the Fund&#x2019;s portfolio investments trade in markets on days and at times when the Fund is not open for business. As a result, the value of the Fund may change, perhaps significantly, on days and at times when shareholders are unable to purchase, redeem, or exchange shares.&lt;/span&gt;</rr:RiskTextBlock>

Fees, expenses, transaction costs, financing costs associated with the use of derivatives, among other factors, will adversely impact the Fund&#x2019;s ability to meet its Daily Target. In addition, the Fund may not have leveraged exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index. Moreover, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may have exposure to the Index that is significantly greater or less than the Daily Target. Any of these factors may prevent the Fund from achieving exposure consistent with the Daily Target. Also, the Fund will measure its correlation to the performance of one or more ETFs. It is important to note that correlation to these ETFs may vary from the correlation to the Index due to embedded costs and other factors.&lt;/span&gt;</rr:RiskTextBlock>

Since the year 2000, Japan&#x2019;s economic growth rate has remained relatively low. As an island nation, Japan has limited natural resources and land area, and the Japanese economy is heavily dependent on international trade and reliant on imports for its commodity needs. Fluctuations or shortages in the commodity markets may negatively impact the Japanese economy. Slowdowns in the U.S. and/or China and other Southeast Asian countries, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;including economic, political or social instability in such &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;countries, could have a negative impact on Japan. Because of its trade dependence, the Japanese economy is particularly exposed to the risks of currency fluctuation, foreign trade policy and regional and global economic disruption, including the risk of increased tariffs, embargoes, and other trade limitations. Strained relationships between Japan and its neighboring countries, including China, South Korea and North Korea, based on historical grievances, territorial disputes, and defense concerns, may also inject uncertainty into Japanese markets. As a result, additional tariffs, other trade barriers, or boycotts may have an adverse impact on the Japanese economy.&lt;/span&gt;</rr:RiskTextBlock>

The Index is a market capitalization-weighted index. The Index is designed to track the performance of a basket of companies that are domiciled in Latin America and that also have level II or III ADR program, New York Shares or Global Registered Shares listed with the NYSE or Nasdaq. Securities eligible for inclusion in the Index are evaluated to ensure their overall consistency with the character, design and purpose of the Index, which is to further its use as an effective benchmark. Decisions regarding additions to and removals from the Index are guided by certain pre-existing objective criteria. As of August 31, 2023, the Index consists of the following Latin American countries: Argentina, Brazil, Chile, Colombia, Mexico and Peru.

For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;fallen on a given day, net assets of the Fund should fall (assuming &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

The use of leverage increases the risk of a total loss of your investment. If the Index approaches a 50% loss at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns. The cost of obtaining this leverage will lower your returns.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -40% return on a yearly basis if the annual Index return were -20%. However, as the table shows, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;with a one-year Index return of -20% and an annualized Index &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;volatility of 50%, the Fund could be expected to return -50.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9pt;font-weight:bold;"&gt;Estimated Fund Returns&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;font-weight:bold;"&gt;Index

For example, two parties may agree to exchange the return (or differentials in rates of returns) earned or realized on a particular investment or instrument.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Futures Contracts&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014;&#160;Standardized contracts that obligate the parties to buy or sell an asset at a predetermined price and date in the future.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:-4.19%;"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Money Market Instruments&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014; The Fund expects that any cash balances maintained in connection with its use of derivatives will typically be held in high quality, short-term money market instruments, for example:&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;U.S. Treasury Bills&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014;&#160;U.S. government securities that have initial maturities of one year or less, and are supported by the full faith and credit of the U.S. government.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Repurchase Agreements&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt; &#x2014; Contracts in which a seller of securities, usually U.S. government securities or other money market instruments, agrees to buy the securities back at a specified time and price.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;ProFund Advisors uses a mathematical approach to investing in &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;which it determines the type, quantity and mix of investment positions that it believes, in combination, the Fund should hold to produce daily returns consistent with the Daily Target. For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;portfolio needs to be rebalanced. For example, if the Index has &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

The use of leverage increases the risk of a total loss of your investment. If the Index approaches a 50% loss at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns. The cost of obtaining this leverage will lower your returns.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;column corresponds to a level of hypothetical annualized &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility. For example, the Fund may mistakenly be expected to achieve a -40% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -50.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9pt;font-weight:bold;"&gt;Estimated Fund Returns&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;font-weight:bold;"&gt;Index

Mid-cap companies may have limited product lines or resources, may be dependent upon a particular market niche and may have greater fluctuations in price than the stocks of larger companies. Mid-cap companies may lack the financial and personnel resources to handle economic or industry-wide setbacks and, as a result, such setbacks could have a greater effect on mid-cap security prices. Additionally, mid-cap company stocks may trade at greater spreads or lower trading volumes, and may be less liquid than the stocks of larger companies. Further, stocks of mid-sized companies could be more difficult to liquidate during market downturns compared to larger, more widely traded companies.&lt;/span&gt;</rr:RiskTextBlock>

For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued).

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -40% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -50.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9pt;font-weight:bold;"&gt;Estimated Fund Returns&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;font-weight:bold;"&gt;Index

For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide inverse leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining inverse leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased. Conversely, if the Index has fallen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns.

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index falls.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -40% return on a yearly basis if the annual Index return were 20%. However, as the table shows, with a one-year Index return of 20% and an annualized Index volatility of 50%, the Fund could be expected to return -67.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain inverse leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

Fees, expenses, transaction costs, financing costs associated with the use of derivatives, among other factors, will adversely impact the Fund&#x2019;s ability to meet its Daily Target. In addition, the Fund may not have inverse leveraged exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index. Moreover, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may have exposure to the Index that is significantly greater or less than the Daily Target. Any of these factors may prevent the Fund from achieving exposure consistent with the Daily Target.&lt;/span&gt;</rr:RiskTextBlock>

Changes in Chinese government policy and economic growth rates could significantly affect local markets and the entire Greater China region. China has yet to develop comprehensive securities, corporate, or commercial laws, and its economy is experiencing a relative slowdown. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Internal social unrest or confrontations with neighboring countries may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations, and higher rates of inflation. Investments in securities of Chinese companies are subject to China&#x2019;s heavy dependence on exports. Reductions in spending on Chinese products and services, institution of tariffs or other trade barriers, including as a result of heightened trade tensions between China and the United States, or a downturn in any of the economies of China&#x2019;s key trading partners may have an adverse impact on the Chinese economy and the values of Chinese companies. Significant portions of the Chinese securities markets may become rapidly illiquid, as Chinese issuers have the ability to suspend the trading of their equity securities and have shown a willingness to exercise that option in response to market volatility and other events. The &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;liquidity of Chinese securities may shrink or disappear &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;suddenly and without warning as a result of adverse economic, market or political events, or adverse investor perceptions, whether or not accurate.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;Investments in issuers in China may include investments &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;through legal structures known as VIEs. In China, ownership of companies in certain sectors by foreign individuals and entities (including U.S. persons and entities such as a Fund) is prohibited. In order to facilitate foreign investment in these businesses, many Chinese companies have created VIEs. In these arrangements, a China-based operating company typically establishes an offshore shell company in another jurisdiction, such as the Cayman Islands. That shell company enters into service and other contracts with the China-based operating company, then issues shares on a foreign exchange, such as the New York Stock Exchange. Foreign investors hold stock in the shell company (i.e., the U.S.-listed company) rather than directly in the China-based operating company. This arrangement allows U.S. investors to obtain economic exposure to the China-based company through contractual means rather than through formal equity ownership. Intervention by the Chinese government with respect to VIEs could significantly affect the Chinese operating company&#x2019;s performance (and, in turn, the Fund&#x2019;s performance) and undermine the enforceability of the VIE structure.&lt;/span&gt;</rr:RiskTextBlock>

For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide inverse leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining inverse leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased. Conversely, if the Index has fallen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index falls.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;expected to achieve a -40% return on a yearly basis if the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;annual Index return were 20%. However, as the table shows, with a one-year Index return of 20% and an annualized Index volatility of 50%, the Fund could be expected to return -67.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain inverse leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

Fees, expenses, transaction costs, financing costs associated with the use of derivatives, among other factors, will adversely impact the Fund&#x2019;s ability to meet its Daily Target. In addition, the Fund may not have inverse leveraged exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index. Moreover, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;have exposure to the Index that is significantly greater or less &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;than the Daily Target.

The Fund may lose money if its derivatives do not perform as expected.

Any costs associated with using derivatives will reduce the Fund&#x2019;s return.&lt;/span&gt;</rr:RiskTextBlock>

Securities eligible for inclusion in the Index are evaluated to ensure their overall consistency with the character, design and purpose of the Index, which is to further its use as an effective benchmark. Decisions regarding additions to and removals from the Index are guided by certain pre-existing objective criteria. As of August 31, 2023, the Index consists of the following emerging market countries: Brazil, China, Chile, India, Indonesia, Mexico, South Africa, South Korea and Taiwan.

However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining inverse leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased. Conversely, if the Index has fallen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index falls.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -40% return on a yearly basis if the annual Index return were 20%. However, as the table shows, &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;with a one-year Index return of 20% and an annualized Index &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;volatility of 50%, the Fund could be expected to return -67.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain inverse leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

Fees, expenses, transaction costs, financing costs associated with the use of derivatives, among other factors, will adversely impact the Fund&#x2019;s ability to meet its Daily Target. In addition, the Fund may not have inverse leveraged exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index. Moreover, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may have exposure to the Index that is significantly greater or less &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;than the Daily Target.

Foreign investments may be more susceptible to political, social, economic and regional factors than may be the case with U.S. securities. In addition, markets for foreign investments are usually less liquid, more volatile and significantly smaller than markets for U.S. securities, which may affect, among other things, the Fund&#x2019;s ability to purchase or sell foreign investments at appropriate times and prices. Because of differences in settlement times and/or foreign market holidays, transactions in a foreign market may take place one or more days after the necessary exposure to these investments is determined.&lt;/span&gt;</rr:RiskTextBlock>

The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased. Conversely, if the Index has fallen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

This is due primarily to the time difference in determining the level of the Index (11:30 a.m., Eastern Time) and valuation of the Fund (4:00 p.m., Eastern Time). As such, correlation to the Index will generally be measured by comparing the daily change in the Fund&#x2019;s NAV per share to the performance of one or more U.S. exchange-traded securities or financial instruments that reflect the values of the securities underlying the Index as of the Fund&#x2019;s NAV calculation time. In addition, in certain cases, the Fund&#x2019;s portfolio investments trade in markets on days and at times when the Fund is not open for business. As a result, the value of the Fund may change, perhaps significantly, on days and at times when shareholders are unable to purchase, redeem, or exchange shares.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index falls.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -40% return on a yearly basis if the annual Index return were 20%. However, as the table shows, with a one-year Index return of 20% and an annualized Index volatility of 50%, the Fund could be expected to return -67.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain inverse leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

Fees, expenses, transaction costs, financing costs associated with the use of derivatives, among other factors, will adversely impact the Fund&#x2019;s ability to meet its Daily Target. In addition, the Fund may not have inverse leveraged exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index. Moreover, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may have exposure to the Index that is significantly greater or less &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;than the Daily Target. Any of these factors may prevent the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Fund from achieving exposure consistent with the Daily Target. Also, the Fund will measure its correlation to the performance of one or more ETFs. It is important to note that correlation to these ETFs may vary from the correlation to the Index due to embedded costs and other factors.&lt;/span&gt;</rr:RiskTextBlock>

The Index is calculated from the prices of the 225 TSE Prime Market stocks selected to represent a broad cross-section of Japanese industries and the overall performance of the Japanese equity market.

The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased. Conversely, if the Index has fallen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

This is due primarily to the time difference in determining the level of the Index (3:00 p.m., Japan Standard Time) and valuation of the Fund (4:00 p.m., Eastern Time). As such, correlation to the Index will generally be measured by comparing the daily change in the Fund&#x2019;s NAV per share to the performance of one or more U.S. exchange-traded securities or financial instruments that reflect the values of the securities underlying the Index as of the Fund&#x2019;s NAV calculation time. In addition, in certain cases, the Fund&#x2019;s portfolio investments trade in markets on days and at times when the Fund is not open for business. As a result, the value of the Fund may change, perhaps significantly, on days and at times when shareholders are unable to purchase, redeem, or exchange shares.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index falls.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -40% return on a yearly basis if the annual Index return were 20%. However, as the table shows, with a one-year Index return of 20% and an annualized Index volatility of 50%, the Fund could be expected to return -67.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain inverse leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

In addition, the Fund may not have inverse leveraged exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index. Moreover, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may have exposure to the Index that is significantly greater or less than the Daily Target. Any of these factors may prevent the Fund from achieving exposure consistent with the Daily Target. Also, the Fund will measure its correlation to the performance of one or more ETFs. It is important to note that correlation to these ETFs may vary from the correlation to the Index due to embedded costs and other factors.&lt;/span&gt;</rr:RiskTextBlock>

Since the year 2000, Japan&#x2019;s economic growth rate has remained relatively low. As an island nation, Japan has limited natural resources and land area, and the Japanese economy is heavily dependent on international trade and reliant on imports for its commodity needs. Fluctuations or shortages in the commodity markets may negatively impact the Japanese economy. Slowdowns in the U.S. and/or China and other Southeast Asian countries, including economic, political or social instability in such countries, could have a negative impact on Japan. Because of its trade dependence, the Japanese economy is particularly exposed to the risks of currency fluctuation, foreign trade &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;policy and regional and global economic disruption, including &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;the risk of increased tariffs, embargoes, and other trade limitations. Strained relationships between Japan and its neighboring countries, including China, South Korea and North Korea, based on historical grievances, territorial disputes, and defense concerns, may also inject uncertainty into Japanese markets.

A higher portfolio turnover rate may indicate higher transaction costs&#160;and may result in higher taxes when the Fund&#x2019;s shares are held in a taxable account. These costs, which are not reflected in the Annual Fund Operating Expenses or in the example above, affect the Fund&#x2019;s performance. During the most recent fiscal year, the Fund&#x2019;s annual portfolio turnover rate was &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;0&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;% of the average value of its portfolio. This portfolio turnover rate is calculated without regard to cash instruments or derivatives transactions. If such transactions were included, the Fund&#x2019;s portfolio turnover rate would be significantly higher.&lt;/span&gt;</rr:PortfolioTurnoverTextBlock>

The Index is a market capitalization-weighted index. The Index is designed to track the performance of a basket of companies that are domiciled in Latin America and that also have level II or III ADR program, New York Shares or Global Registered Shares listed with the NYSE or Nasdaq. Securities eligible for inclusion in the Index are evaluated to ensure their overall consistency with the character, design and purpose of the Index, which is to further its use as an effective benchmark. Decisions regarding additions to and removals from the Index are guided by certain pre-existing objective criteria.

The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased. Conversely, if the Index has fallen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index falls.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -40% return on a yearly basis if the annual Index return were 20%. However, as the table shows, with a one-year Index return of 20% and an annualized Index volatility of 50%, the Fund could be expected to return -67.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain inverse leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

Fees, expenses, transaction costs, financing costs associated with the use of derivatives, among other factors, will adversely impact the Fund&#x2019;s ability to meet its Daily Target. In addition, the Fund may not have inverse leveraged exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index. Moreover, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may have exposure to the Index that is significantly greater or less than the Daily Target. Any of these factors may prevent the Fund from achieving exposure consistent with the Daily Target.&lt;/span&gt;</rr:RiskTextBlock>

For example, two parties may agree to exchange the return (or differentials in rates of returns) earned or realized on a particular investment or instrument.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Futures Contracts&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014;&#160;Standardized contracts that obligate the parties to buy or sell an asset at a predetermined price and date in the future.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:-4.19%;"&gt;&#x2022;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Money Market Instruments&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014; The Fund expects that any cash balances maintained in connection with its use of derivatives will typically be held in high quality, short-term money market instruments, for example:&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;U.S. Treasury Bills&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;&#160;&#x2014;&#160;U.S. government securities that have initial maturities of one year or less, and are supported by the full faith and credit of the U.S. government.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:7pt;margin-left:-3.90%;"&gt;&#x25cb;&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:6pt;"&gt;Repurchase Agreements&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt; &#x2014; Contracts in which a seller of securities, usually U.S. government securities or other money market instruments, agrees to buy the securities back at a specified time and price.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;ProFund Advisors uses a mathematical approach to investing in &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;which it determines the type, quantity and mix of investment positions that it believes, in combination, the Fund should hold to produce daily returns consistent with the Daily Target. For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide inverse leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining inverse leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased. Conversely, if the Index has fallen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns.

Mid-cap companies may have limited product lines or resources, may be dependent upon a particular market niche and may have greater fluctuations in price than the stocks of larger companies. Mid-cap companies may lack the financial and personnel resources to handle economic or industry-wide setbacks and, as a result, such setbacks could have a greater effect on mid-cap security prices. Additionally, mid-cap company stocks may trade at greater spreads or lower trading volumes, and may be less liquid than the stocks of larger companies. Further, stocks of mid-sized companies could be more difficult to liquidate during market downturns compared to larger, more widely traded companies.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index falls.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -40% return on a yearly basis if the annual Index return were 20%. However, as the table shows, with a one-year Index return of 20% and an annualized Index volatility of 50%, the Fund could be expected to return -67.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain inverse leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

Fees, expenses, transaction costs, financing costs associated with the use of derivatives, among other factors, will adversely impact the Fund&#x2019;s ability to meet its Daily Target. In addition, the Fund may not have inverse leveraged exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index. Moreover, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may have exposure to the Index that is significantly greater or less &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;than the Daily Target.

Conversely, if the Index has fallen on a given day, net assets of the Fund should rise (assuming there were no share redemptions).

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;the Index return is flat (i.e., close to zero) and you may lose &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;money when the Index falls.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -40% return on a yearly basis if the annual Index return were 20%. However, as the table shows, with a one-year Index return of 20% and an annualized Index volatility of 50%, the Fund could be expected to return -67.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain inverse leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

In addition, the Fund may not have inverse leveraged exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index. Moreover, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may have exposure to the Index that is significantly greater or less than the Daily Target. Any of these factors may prevent the Fund from achieving exposure consistent with the Daily Target.&lt;/span&gt;</rr:RiskTextBlock>

For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide inverse leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining inverse leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased. Conversely, if the Index has fallen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns.

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index falls.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -40% return on a yearly basis if the annual Index return were 20%. However, as the table shows, with a one-year Index return of 20% and an annualized Index volatility of 50%, the Fund could be expected to return -67.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain inverse leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

Fees, expenses, transaction costs, financing costs associated with the use of derivatives, among other factors, will adversely impact the Fund&#x2019;s ability to meet its Daily Target. In addition, the Fund may not have inverse leveraged exposure to all of the securities in the Index, its weighting of securities may be different from that of the Index, and it may invest in instruments not included in the Index. Moreover, if for any reason the Fund is unable to rebalance all or a portion of its investments, the Fund may have exposure to the Index that is significantly greater or less than the Daily Target. Any of these factors may prevent the Fund from achieving exposure consistent with the Daily Target.&lt;/span&gt;</rr:RiskTextBlock>

Small-cap companies may have limited product lines or resources, may be dependent upon a particular market niche and may have greater fluctuations in price than the stocks of larger companies. Small-cap companies may lack the financial and personnel resources to handle economic or industry-wide setbacks and, as a result, such setbacks could have a greater effect on small-cap security prices. Additionally, small-cap company stocks may trade at greater spreads or lower trading volumes, and may be less liquid than the stocks of larger companies.

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;margin-left:0.00%;"&gt;considering holding fund shares for longer than a day, it&#x2019;s &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -40% return on a yearly basis if the annual Index return were 20%. However, as the table shows, with a one-year Index return of 20% and an annualized Index volatility of 50%, the Fund could be expected to return -67.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:9pt;font-weight:bold;"&gt;Estimated Fund Returns&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;font-weight:bold;"&gt;Index

Small-cap companies may have limited product lines or resources, may be dependent upon a particular market niche and may have greater fluctuations in price than the stocks of larger companies. Small-cap companies may lack the financial and personnel resources to handle economic or industry-wide setbacks and, as a result, such setbacks could have a greater effect on small-cap security prices. Additionally, small-cap company stocks &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;may trade at greater spreads or lower trading volumes, and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;may be less liquid than the stocks of larger companies.

For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Long Bond or to securities not contained in the Long Bond or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Long Bond is consistent with the Daily Target. The Long Bond&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Long Bond has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Long Bond has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

The use of leverage increases the risk of a total loss of your investment. If the Long Bond approaches a 80% loss at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns. The cost of obtaining this leverage will lower your returns.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Long Bond returns and Long Bond volatility (how much the value of the Long Bond moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Long Bond volatility has a negative impact on Fund returns. During periods of higher Long Bond volatility, the Long Bond volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Long Bond.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Long Bond &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;volatility and Long Bond return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Long Bond gains or losses and higher Long Bond volatility. Your return will tend to be better than the Daily Target when there are larger Long Bond gains or losses and lower Long Bond volatility. You may lose money when the Long Bond return is flat (i.e., close to zero) and you may lose money when the Long Bond rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Long Bond volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Long Bond returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Long Bond return for a one-year period. Each column corresponds to a level of hypothetical annualized Long Bond volatility. For example, the Fund may mistakenly be expected to achieve a -25% return on a yearly basis if the annual Long Bond return were -20%. However, as the table shows, with a one-year Long Bond return of -20% and an annualized Long Bond volatility of 50%, the Fund could be expected to return -27.2%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Long Bond; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

Fees, expenses, transaction costs, financing costs associated with the use of derivatives, among other factors, will adversely impact the Fund&#x2019;s ability to meet its Daily Target. In addition, the Fund may not have leveraged exposure to all of the securities in the Long Bond, its weighting of securities may be different from that of the Long Bond, and it may invest in instruments not included in the Long Bond. Moreover, if for any reason the Fund is unable to &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;rebalance all or a portion of its investments, the Fund may &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;have exposure to the Long Bond that is significantly greater or less than the Daily Target.

In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve its investment objective.&lt;/span&gt;</rr:RiskTextBlock>

A wide variety of factors can cause interest rates to fluctuate (e.g., central bank monetary policies, inflation rates, general economic conditions, etc.). Commonly, investments subject to interest rate risk will decrease in value when interest rates rise and increase in value when interest rates decline. A rising interest rate environment may cause the value of debt instruments to decrease and adversely impact the liquidity of debt instruments. Without taking into account other factors, the value of securities with longer maturities typically fluctuates more in response to interest rate changes than securities with &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;shorter maturities.

For these purposes a day is measured from the time of one net asset value (&#x201c;NAV&#x201d;) calculation to the next.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to remain fully invested at all times in financial &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. However, the Fund may invest in or gain exposure to only a representative sample of the securities in the Index or to securities not contained in the Index or in financial instruments, with the intent of obtaining leveraged exposure consistent with the investment objective.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;The Fund seeks to rebalance its portfolio each day so that its &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;exposure to the Index is consistent with the Daily Target. The Index&#x2019;s movements during the day will affect whether the Fund&#x2019;s portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no share redemptions). As a result, the Fund&#x2019;s exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no shares issued). As a result, the Fund&#x2019;s exposure will need to be decreased.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0%;"&gt;Please see &#x201c;Investment Objectives, Principal Investment Strategies &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Related Risks&#x201d; in the Fund&#x2019;s Prospectus for additional details.&lt;/span&gt;</rr:StrategyNarrativeTextBlock>

The use of leverage increases the &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;risk of a total loss of your investment. If the Index approaches a 67% loss at any point in the day, you could lose your entire investment. As a result, an investment in the Fund may not be suitable for all investors. The use of leverage increases the volatility of your returns. The cost of obtaining this leverage will lower your returns.&lt;/span&gt;</rr:RiskTextBlock>

This difference may be significant. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;If you are considering holding fund shares for longer than a day, it&#x2019;s important that you understand the impact of Index returns and Index volatility (how much the value of the Index moves up and down from day-to-day) on your holding period return. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index volatility has a negative impact on Fund returns. During periods of higher Index volatility, the Index volatility may affect the Fund&#x2019;s returns as much as or more than the return of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The following table illustrates the impact of Index volatility &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;and Index return on Fund returns for a hypothetical one-year period. However, these effects will impact your return for any holding period other than a day. &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;"&gt;The longer you hold shares of the Fund, the more magnified these effects will be. As a result, you should consider monitoring your investments in the Fund in light of your individual investment goals and risk tolerance.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;In the table areas shaded darker represent those scenarios &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;where the Fund can be expected to return less than the Daily Target. As the table shows, your return will tend to be worse than the Daily Target when there are smaller Index gains or losses and higher Index volatility. Your return will tend to be better than the Daily Target when there are larger Index gains or losses and lower Index volatility. You may lose money when the Index return is flat (i.e., close to zero) and you may lose money when the Index rises.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;margin-left:0.00%;"&gt;The table uses hypothetical annualized Index volatility and &lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:10pt;"&gt;Index returns to illustrate the impact of these two factors on Fund performance over a one-year period. It does not represent actual returns. Each row corresponds to the level of a hypothetical Index return for a one-year period. Each column corresponds to a level of hypothetical annualized Index volatility. For example, the Fund may mistakenly be expected to achieve a -30% return on a yearly basis if the annual Index return were -20%. However, as the table shows, with a one-year Index return of -20% and an annualized Index volatility of 50%, the Fund could be expected to return -34.8%.&lt;/span&gt;&lt;span style="color:#000000;font-family:Arial;font-size:8pt;"&gt;Assumes: (a) no dividends paid with respect to securities included in the Index; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leveraged exposure) of zero percent. If these were included the Fund&#x2019;s performance would be different from that shown.&lt;/span&gt;</rr:RiskTextBlock>

The Fund may lose money if its derivatives do not perform as expected. To the extent to the Fund invests in swaps that use an ETF as the reference asset, the Fund may be subject to greater correlation risk since the performance of an ETF may not track the performance of the Index.
