As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Example Investment Objective The Fund's Shares will change in value, and you could lose money by investing in the Fund. Principal Risks of Investing in the Fund Although your actual costs may be higher or lower, your costs, based on these assumptions, would be: Performance <pre>The Fund will invest under normal circumstances at least 80% of its net assets (plus any borrowings for investment purposes) in senior loans. The Adviser and Invesco Senior Secured Management, Inc. (the "Sub-Adviser"), the Fund's sub-adviser, define senior loans to include loans referred to as leveraged loans, bank loans and/or floating rate loans. Senior loans, generally made by banks and other lending institutions, are made to or issued by corporations, partnerships or other entities ("borrowers"). These borrowers operate in a variety of industries and geographic regions. The Fund will invest at least 80% of its total assets in the component securities that comprise the Underlying Index. The Underlying Index is compiled, maintained and calculated by Standard & Poor's. The Underlying Index is designed to track the market-weighted performance of the largest institutional leveraged loans based on market weightings, spreads and interest payments. As of the date of this Prospectus, there were 100 loans included in the Underlying Index. A leveraged loan is rated below investment grade quality or is unrated but deemed to be of comparable quality. The loans in which the Fund will invest are expected to be below investment grade quality and to bear interest at a floating rate that resets periodically. The Underlying Index may include, and the Fund may acquire and retain in its portfolio, loans of borrowers that have filed for bankruptcy protection. The Fund may also invest up to 20% of its assets in closed-end funds that invest all or a portion of their assets in senior loans and in other liquid instruments such as high yield securities (commonly known as "junk bonds"). Senior loans are often issued in connection with recapitalizations, acquisitions, leveraged buyouts and refinancings. Senior loans are typically structured and administered by a financial institution that acts as agent for the lenders in the lending group. The Fund will generally purchase loans from banks or other financial institutions through assignments or participations. The Fund may acquire a direct interest in a loan from the agent or another lender by assignment or an indirect interest in a loan as a participation in another lender's portion of a loan. The Fund will generally sell loans it holds by way of an assignment, but may at any time facilitate its ability to fund redemption requests by selling participation interests in such loans. The Fund does not purchase all of the securities in the Underlying Index. Instead, the Fund utilizes a "sampling" methodology in seeking to achieve the Fund's investment objective. Concentration Policy. The Fund will invest 25% or more of the value of its total assets in securities of issuers in an industry or group of industries to the extent that the Underlying Index concentrates in an industry or group of industries.</pre> PowerShares Senior Loan Portfolio Portfolio Turnover <pre>The following summarizes the principal risks that have been identified for the Fund. Risk of Investing in Loans. Investments in loans are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a loan resulting from changes in the general level of interest rates. Credit risk refers to the possibility that the borrower of a loan will be unable and/or unwilling to make timely interest payments and/or repay the principal on its obligation. Default in the payment of interest or principal on a loan will result in a reduction in the value of the loan and consequently a reduction in the value of the Fund's investments and a potential decrease in the net asset value ("NAV") of the Fund. Although the loans in which the Fund will invest generally will be secured by specific collateral, there can be no assurance that such collateral would satisfy the borrower's obligation in the event of non-payment of scheduled interest or principal or that such collateral could be readily liquidated. In the event of the bankruptcy of a borrower, the Fund's access to the collateral may be limited by bankruptcy or other insolvency loans and, therefore, the Fund could experience delays or limitations with respect to its ability to realize the benefits of the collateral securing a loan. There is no organized exchange on which loans are traded and reliable market quotations may not be readily available. Therefore, elements of judgment may play a greater role in valuation of loans than for securities with a more developed secondary market and the Fund may not realize full value in the event of the need to sell a loan. To the extent that a secondary market does exist for certain loans, the market may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Some loans are subject to the risk that a court, pursuant to fraudulent conveyance or other similar laws, could subordinate the loans to presently existing or future indebtedness of the borrower or take other action detrimental to lenders, including the Fund, such as invalidation of loans or causing interest previously paid to be refunded to the borrower. Investments in loans are also subject to the risk of changes in legislation or state or federal regulations. If such legislation or regulations impose additional requirements or restrictions on the ability of financial institutions to make loans, the availability of loans for investment by the Fund may be adversely affected. Many loans are not registered with the SEC or any state securities commission and are not often rated by any nationally recognized rating service. Generally there is less readily available, reliable information about most loans than is the case for many other types of securities. Although a loan may be senior to equity and other debt securities in a borrower's capital structure, such obligations may be structurally subordinated to obligations of the borrower's subsidiaries. From time to time, one or more of the factors described above may create volatility in the markets for debt instruments and decrease the liquidity of the loan market. Risks of Loan Assignments and Participations. As the purchaser of an assignment, the Fund typically succeeds to all the rights and obligations of the assigning institution and becomes a lender under the credit agreement with respect to the debt obligation; however, the Fund may not be able to unilaterally enforce all rights and remedies under the loan and with regard to any associated collateral. Because assignments may be arranged through private negotiations between potential assignees and potential assignors, the rights and obligations acquired by the Fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. In addition, if the loan is foreclosed, the Fund could become part owner of any collateral and could bear the costs and liabilities of owning and disposing of the collateral. The Fund may be required to pass along to a purchaser that buys a loan from the Fund by way of assignment a portion of any fees to which the Fund is entitled under the loan. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. As a result, the Fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a participation, the Fund may be treated as a general creditor of the lender and may not benefit from any set-off between the lender and the borrower. Non-Investment Grade Securities Risk. All or a significant portion of the loans in which the Fund will invest may be determined to be non-investment grade loans that are considered speculative. The Fund may also invest in non-investment grade, or "high yield," securities ("junk bonds"). Non-investment grade loans and bonds, and unrated loans and bonds of comparable credit quality are subject to the increased risk of a borrower's or issuer's inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of the non-investment grade securities markets generally, real or perceived adverse economic and competitive industry conditions and less secondary market liquidity. If the borrower of lower-rated loans or issuer of lower-rated bonds defaults, the Fund may incur additional expenses to seek recovery. Prepayment Risk. The ability of the borrower of a loan to repay principal prior to maturity can limit the potential for gains by the Fund. During periods of declining interest rates, the borrower of a loan may exercise its option to prepay principal earlier than scheduled, forcing the Underlying Index, and therefore the Fund, to replace such a loan with a lower yielding loan. If interest rates are falling, the Fund may have to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund's income. Reinvestment Risk. Proceeds from a current investment of the Fund, both interest payments and principal payments, may be reinvested in instruments that offer lower yields than the current investment due in part to market conditions and the interest rate environment at the time of reinvestment. Reinvestment risk is greater on short- to intermediate-term loans. Liquidity Risk. A majority of the Fund's assets are likely to be invested in loans that are less liquid than securities traded on national exchanges. Loans with reduced liquidity involve greater risk than securities with more liquid markets. Available market quotations for such loans may vary over time, and if the credit quality of a loan unexpectedly declines, secondary trading of that loan may decline for a period of time. In the event that the Fund voluntarily or involuntarily liquidates portfolio assets during periods of infrequent trading, it may not receive full value for those assets. Risks of Investing in Closed-End Funds. The shares of closed-end funds may trade at a discount or premium to, or at, their NAV. To the extent that the Fund invests a portion of its assets in closed-end funds, those assets will be subject to the risks of the closed-end fund's portfolio securities, and a shareholder in the Fund will bear not only his or her proportionate share of the expenses of the Fund, but also, indirectly, the expenses of the closed-end fund. The securities of closed-end funds in which the Fund may invest may be leveraged. As a result, the Fund may be indirectly exposed to leverage through an investment in such securities. An investment in securities of closed-end funds that use leverage may expose the Fund to higher volatility in the market value of such securities and the possibility that the Fund's long-term returns on such securities (and, indirectly, the long-term returns of the Shares) will be diminished. Risk of Investing in Loans to Non-U.S. Borrowers. The Fund may invest all or a portion of its assets in loans of non-U.S. borrowers. The Fund's investments in loans of non-U.S. borrowers may be affected by political and social instability; changes in economic or taxation policies; difficulties when enforcing obligations; decreased liquidity; and increased volatility. Foreign borrowers may be subject to less regulation resulting in less publicly available information about the borrowers. Sampling Risk. The Fund's use of a representative sampling approach will result in its holding a smaller number of loans than are in the Underlying Index. As a result, an adverse development respecting a borrower of a loan held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the loans in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. Because the Fund issues and redeems Creation Units for cash, it will incur higher costs in buying and selling securities than if it issued and redeemed Creation Units in-kind. Additionally, the Fund's use of a representative sampling approach may cause the Fund to not be as well correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. For example, the Fund expects to invest up to 20% of its assets in closed-end funds that, in turn, invest in senior loans, to increase liquidity while providing exposure to senior loans. Cash Transaction Risk. Unlike most exchange-traded funds ("ETFs"), the Fund currently intends to effect creations and redemptions principally for cash, rather than primarily in-kind because of the nature of the Fund's investments. As such, investments in Shares may be less tax efficient than investments in conventional ETFs. Portfolio Turnover Risk. The Fund may engage in frequent trading of its portfolio securities in connection with the rebalancing or adjustment of the Underlying Index. A portfolio turnover rate of 200%, for example, is equivalent to the Fund buying and selling all of its securities two times during the course of a year. A high portfolio turnover rate (such as 100% or more) could result in high brokerage costs for the Fund. A high portfolio turnover rate can result in an increase in taxable capital gains distributions to the Fund's shareholders. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Concentration Risk. A significant percentage of the Underlying Index may be comprised of issuers in a single industry or group of industries. If the Fund is focused in an industry or group of industries, it may present more risks than if it were broadly diversified over numerous industries and groups of industries. The Fund's Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.</pre> Fund Fees and Expenses Principal Investment Strategies www.InvescoPowerShares.com The Fund will invest 25% or more of the value of its total assets in securities of issuers in an industry or group of industries to the extent that the Underlying Index concentrates in an industry or group of industries. <pre>The Fund has not yet commenced operations and therefore does not have a performance history.

The Adviser and Invesco Senior Secured Management, Inc. (the "Sub-Adviser"), the Fund's sub-adviser, define senior loans to include loans referred to as leveraged loans, bank loans and/or floating rate loans. Senior loans, generally made by banks and other lending institutions, are made to or issued by corporations, partnerships or other entities ("borrowers"). These borrowers operate in a variety of industries and geographic regions. The Fund will invest at least 80% of its total assets in the component securities that comprise the Underlying Index. The Underlying Index is compiled, maintained and calculated by Standard & Poor's. The Underlying Index is designed to track the market-weighted performance of the largest institutional leveraged loans based on market weightings, spreads and interest payments. As of the date of this Prospectus, there were 100 loans included in the Underlying Index. A leveraged loan is rated below investment grade quality or is unrated but deemed to be of comparable quality. The loans in which the Fund will invest are expected to be below investment grade quality and to bear interest at a floating rate that resets periodically. The Underlying Index may include, and the Fund may acquire and retain in its portfolio, loans of borrowers that have filed for bankruptcy protection. The Fund may also invest up to 20% of its assets in closed-end funds that invest all or a portion of their assets in senior loans and in other liquid instruments such as high yield securities (commonly known as "junk bonds"). Senior loans are often issued in connection with recapitalizations, acquisitions, leveraged buyouts and refinancings. Senior loans are typically structured and administered by a financial institution that acts as agent for the lenders in the lending group. The Fund will generally purchase loans from banks or other financial institutions through assignments or participations. The Fund may acquire a direct interest in a loan from the agent or another lender by assignment or an indirect interest in a loan as a participation in another lender's portion of a loan. The Fund will generally sell loans it holds by way of an assignment, but may at any time facilitate its ability to fund redemption requests by selling participation interests in such loans. The Fund does not purchase all of the securities in the Underlying Index. Instead, the Fund utilizes a "sampling" methodology in seeking to achieve the Fund's investment objective.

Risk of Investing in Loans. Investments in loans are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a loan resulting from changes in the general level of interest rates. Credit risk refers to the possibility that the borrower of a loan will be unable and/or unwilling to make timely interest payments and/or repay the principal on its obligation. Default in the payment of interest or principal on a loan will result in a reduction in the value of the loan and consequently a reduction in the value of the Fund's investments and a potential decrease in the net asset value ("NAV") of the Fund. Although the loans in which the Fund will invest generally will be secured by specific collateral, there can be no assurance that such collateral would satisfy the borrower's obligation in the event of non-payment of scheduled interest or principal or that such collateral could be readily liquidated. In the event of the bankruptcy of a borrower, the Fund's access to the collateral may be limited by bankruptcy or other insolvency loans and, therefore, the Fund could experience delays or limitations with respect to its ability to realize the benefits of the collateral securing a loan. There is no organized exchange on which loans are traded and reliable market quotations may not be readily available. Therefore, elements of judgment may play a greater role in valuation of loans than for securities with a more developed secondary market and the Fund may not realize full value in the event of the need to sell a loan. To the extent that a secondary market does exist for certain loans, the market may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Some loans are subject to the risk that a court, pursuant to fraudulent conveyance or other similar laws, could subordinate the loans to presently existing or future indebtedness of the borrower or take other action detrimental to lenders, including the Fund, such as invalidation of loans or causing interest previously paid to be refunded to the borrower. Investments in loans are also subject to the risk of changes in legislation or state or federal regulations. If such legislation or regulations impose additional requirements or restrictions on the ability of financial institutions to make loans, the availability of loans for investment by the Fund may be adversely affected. Many loans are not registered with the SEC or any state securities commission and are not often rated by any nationally recognized rating service. Generally there is less readily available, reliable information about most loans than is the case for many other types of securities. Although a loan may be senior to equity and other debt securities in a borrower's capital structure, such obligations may be structurally subordinated to obligations of the borrower's subsidiaries. From time to time, one or more of the factors described above may create volatility in the markets for debt instruments and decrease the liquidity of the loan market. Risks of Loan Assignments and Participations. As the purchaser of an assignment, the Fund typically succeeds to all the rights and obligations of the assigning institution and becomes a lender under the credit agreement with respect to the debt obligation; however, the Fund may not be able to unilaterally enforce all rights and remedies under the loan and with regard to any associated collateral. Because assignments may be arranged through private negotiations between potential assignees and potential assignors, the rights and obligations acquired by the Fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. In addition, if the loan is foreclosed, the Fund could become part owner of any collateral and could bear the costs and liabilities of owning and disposing of the collateral. The Fund may be required to pass along to a purchaser that buys a loan from the Fund by way of assignment a portion of any fees to which the Fund is entitled under the loan. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. As a result, the Fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a participation, the Fund may be treated as a general creditor of the lender and may not benefit from any set-off between the lender and the borrower. Non-Investment Grade Securities Risk. All or a significant portion of the loans in which the Fund will invest may be determined to be non-investment grade loans that are considered speculative. The Fund may also invest in non-investment grade, or "high yield," securities ("junk bonds"). Non-investment grade loans and bonds, and unrated loans and bonds of comparable credit quality are subject to the increased risk of a borrower's or issuer's inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of the non-investment grade securities markets generally, real or perceived adverse economic and competitive industry conditions and less secondary market liquidity. If the borrower of lower-rated loans or issuer of lower-rated bonds defaults, the Fund may incur additional expenses to seek recovery. Prepayment Risk. The ability of the borrower of a loan to repay principal prior to maturity can limit the potential for gains by the Fund. During periods of declining interest rates, the borrower of a loan may exercise its option to prepay principal earlier than scheduled, forcing the Underlying Index, and therefore the Fund, to replace such a loan with a lower yielding loan. If interest rates are falling, the Fund may have to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund's income. Reinvestment Risk. Proceeds from a current investment of the Fund, both interest payments and principal payments, may be reinvested in instruments that offer lower yields than the current investment due in part to market conditions and the interest rate environment at the time of reinvestment. Reinvestment risk is greater on short- to intermediate-term loans. Liquidity Risk. A majority of the Fund's assets are likely to be invested in loans that are less liquid than securities traded on national exchanges. Loans with reduced liquidity involve greater risk than securities with more liquid markets. Available market quotations for such loans may vary over time, and if the credit quality of a loan unexpectedly declines, secondary trading of that loan may decline for a period of time. In the event that the Fund voluntarily or involuntarily liquidates portfolio assets during periods of infrequent trading, it may not receive full value for those assets. Risks of Investing in Closed-End Funds. The shares of closed-end funds may trade at a discount or premium to, or at, their NAV. To the extent that the Fund invests a portion of its assets in closed-end funds, those assets will be subject to the risks of the closed-end fund's portfolio securities, and a shareholder in the Fund will bear not only his or her proportionate share of the expenses of the Fund, but also, indirectly, the expenses of the closed-end fund. The securities of closed-end funds in which the Fund may invest may be leveraged. As a result, the Fund may be indirectly exposed to leverage through an investment in such securities. An investment in securities of closed-end funds that use leverage may expose the Fund to higher volatility in the market value of such securities and the possibility that the Fund's long-term returns on such securities (and, indirectly, the long-term returns of the Shares) will be diminished. Risk of Investing in Loans to Non-U.S. Borrowers. The Fund may invest all or a portion of its assets in loans of non-U.S. borrowers. The Fund's investments in loans of non-U.S. borrowers may be affected by political and social instability; changes in economic or taxation policies; difficulties when enforcing obligations; decreased liquidity; and increased volatility. Foreign borrowers may be subject to less regulation resulting in less publicly available information about the borrowers. Sampling Risk. The Fund's use of a representative sampling approach will result in its holding a smaller number of loans than are in the Underlying Index. As a result, an adverse development respecting a borrower of a loan held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the loans in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. Because the Fund issues and redeems Creation Units for cash, it will incur higher costs in buying and selling securities than if it issued and redeemed Creation Units in-kind. Additionally, the Fund's use of a representative sampling approach may cause the Fund to not be as well correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. For example, the Fund expects to invest up to 20% of its assets in closed-end funds that, in turn, invest in senior loans, to increase liquidity while providing exposure to senior loans. Cash Transaction Risk. Unlike most exchange-traded funds ("ETFs"), the Fund currently intends to effect creations and redemptions principally for cash, rather than primarily in-kind because of the nature of the Fund's investments. As such, investments in Shares may be less tax efficient than investments in conventional ETFs. Portfolio Turnover Risk. The Fund may engage in frequent trading of its portfolio securities in connection with the rebalancing or adjustment of the Underlying Index. A portfolio turnover rate of 200%, for example, is equivalent to the Fund buying and selling all of its securities two times during the course of a year. A high portfolio turnover rate (such as 100% or more) could result in high brokerage costs for the Fund. A high portfolio turnover rate can result in an increase in taxable capital gains distributions to the Fund's shareholders. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Concentration Risk. A significant percentage of the Underlying Index may be comprised of issuers in a single industry or group of industries. If the Fund is focused in an industry or group of industries, it may present more risks than if it were broadly diversified over numerous industries and groups of industries.

If there were expense reimbursement or fee waiver arrangements that reduced any Fund operating expenses and will continue to reduce them for no less than one year from the effective date of the Fund's registration statement, a Fund may add two captions to the table one caption showing the amount of the expense reimbursement or fee waiver, and a second caption showing the Fund's net expenses after subtracting the fee reimbursement or expense waiver from the total fund operating expenses. The Fund should place these additional captions directly below the "Total Annual Fund Operating Expenses" caption of the table and should use appropriate descriptive captions, such as "Fee Waiver [and/or Expense Reimbursement]" and "Total Annual Fund Operating Expenses After Fee Waiver [and/or Expense Reimbursement]," respectively.

The Adviser and Invesco Senior Secured Management, Inc. (the "Sub-Adviser"), the Fund's sub-adviser, define senior loans to include loans referred to as leveraged loans, bank loans and/or floating rate loans. Senior loans, generally made by banks and other lending institutions, are made to or issued by corporations, partnerships or other entities ("borrowers"). These borrowers operate in a variety of industries and geographic regions. The Fund will invest at least 80% of its total assets in the component securities that comprise the Underlying Index. The Underlying Index is compiled, maintained and calculated by Standard & Poor's. The Underlying Index is designed to track the market-weighted performance of the largest institutional leveraged loans based on market weightings, spreads and interest payments. As of the date of this Prospectus, there were 100 loans included in the Underlying Index. A leveraged loan is rated below investment grade quality or is unrated but deemed to be of comparable quality. The loans in which the Fund will invest are expected to be below investment grade quality and to bear interest at a floating rate that resets periodically. The Underlying Index may include, and the Fund may acquire and retain in its portfolio, loans of borrowers that have filed for bankruptcy protection. The Fund may also invest up to 20% of its assets in closed-end funds that invest all or a portion of their assets in senior loans and in other liquid instruments such as high yield securities (commonly known as "junk bonds"). Senior loans are often issued in connection with recapitalizations, acquisitions, leveraged buyouts and refinancings. Senior loans are typically structured and administered by a financial institution that acts as agent for the lenders in the lending group. The Fund will generally purchase loans from banks or other financial institutions through assignments or participations. The Fund may acquire a direct interest in a loan from the agent or another lender by assignment or an indirect interest in a loan as a participation in another lender's portion of a loan. The Fund will generally sell loans it holds by way of an assignment, but may at any time facilitate its ability to fund redemption requests by selling participation interests in such loans. The Fund does not purchase all of the securities in the Underlying Index. Instead, the Fund utilizes a "sampling" methodology in seeking to achieve the Fund's investment objective. Concentration Policy. The Fund will invest 25% or more of the value of its total assets in securities of issuers in an industry or group of industries to the extent that the Underlying Index concentrates in an industry or group of industries.</pre>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Risk of Investing in Loans. Investments in loans are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a loan resulting from changes in the general level of interest rates. Credit risk refers to the possibility that the borrower of a loan will be unable and/or unwilling to make timely interest payments and/or repay the principal on its obligation. Default in the payment of interest or principal on a loan will result in a reduction in the value of the loan and consequently a reduction in the value of the Fund's investments and a potential decrease in the net asset value ("NAV") of the Fund. Although the loans in which the Fund will invest generally will be secured by specific collateral, there can be no assurance that such collateral would satisfy the borrower's obligation in the event of non-payment of scheduled interest or principal or that such collateral could be readily liquidated. In the event of the bankruptcy of a borrower, the Fund's access to the collateral may be limited by bankruptcy or other insolvency loans and, therefore, the Fund could experience delays or limitations with respect to its ability to realize the benefits of the collateral securing a loan. There is no organized exchange on which loans are traded and reliable market quotations may not be readily available. Therefore, elements of judgment may play a greater role in valuation of loans than for securities with a more developed secondary market and the Fund may not realize full value in the event of the need to sell a loan. To the extent that a secondary market does exist for certain loans, the market may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods. Some loans are subject to the risk that a court, pursuant to fraudulent conveyance or other similar laws, could subordinate the loans to presently existing or future indebtedness of the borrower or take other action detrimental to lenders, including the Fund, such as invalidation of loans or causing interest previously paid to be refunded to the borrower. Investments in loans are also subject to the risk of changes in legislation or state or federal regulations. If such legislation or regulations impose additional requirements or restrictions on the ability of financial institutions to make loans, the availability of loans for investment by the Fund may be adversely affected. Many loans are not registered with the SEC or any state securities commission and are not often rated by any nationally recognized rating service. Generally there is less readily available, reliable information about most loans than is the case for many other types of securities. Although a loan may be senior to equity and other debt securities in a borrower's capital structure, such obligations may be structurally subordinated to obligations of the borrower's subsidiaries. From time to time, one or more of the factors described above may create volatility in the markets for debt instruments and decrease the liquidity of the loan market. Risks of Loan Assignments and Participations. As the purchaser of an assignment, the Fund typically succeeds to all the rights and obligations of the assigning institution and becomes a lender under the credit agreement with respect to the debt obligation; however, the Fund may not be able to unilaterally enforce all rights and remedies under the loan and with regard to any associated collateral. Because assignments may be arranged through private negotiations between potential assignees and potential assignors, the rights and obligations acquired by the Fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. In addition, if the loan is foreclosed, the Fund could become part owner of any collateral and could bear the costs and liabilities of owning and disposing of the collateral. The Fund may be required to pass along to a purchaser that buys a loan from the Fund by way of assignment a portion of any fees to which the Fund is entitled under the loan. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. As a result, the Fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a participation, the Fund may be treated as a general creditor of the lender and may not benefit from any set-off between the lender and the borrower. Non-Investment Grade Securities Risk. All or a significant portion of the loans in which the Fund will invest may be determined to be non-investment grade loans that are considered speculative. The Fund may also invest in non-investment grade, or "high yield," securities ("junk bonds"). Non-investment grade loans and bonds, and unrated loans and bonds of comparable credit quality are subject to the increased risk of a borrower's or issuer's inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of the non-investment grade securities markets generally, real or perceived adverse economic and competitive industry conditions and less secondary market liquidity. If the borrower of lower-rated loans or issuer of lower-rated bonds defaults, the Fund may incur additional expenses to seek recovery. Prepayment Risk. The ability of the borrower of a loan to repay principal prior to maturity can limit the potential for gains by the Fund. During periods of declining interest rates, the borrower of a loan may exercise its option to prepay principal earlier than scheduled, forcing the Underlying Index, and therefore the Fund, to replace such a loan with a lower yielding loan. If interest rates are falling, the Fund may have to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund's income. Reinvestment Risk. Proceeds from a current investment of the Fund, both interest payments and principal payments, may be reinvested in instruments that offer lower yields than the current investment due in part to market conditions and the interest rate environment at the time of reinvestment. Reinvestment risk is greater on short- to intermediate-term loans. Liquidity Risk. A majority of the Fund's assets are likely to be invested in loans that are less liquid than securities traded on national exchanges. Loans with reduced liquidity involve greater risk than securities with more liquid markets. Available market quotations for such loans may vary over time, and if the credit quality of a loan unexpectedly declines, secondary trading of that loan may decline for a period of time. In the event that the Fund voluntarily or involuntarily liquidates portfolio assets during periods of infrequent trading, it may not receive full value for those assets. Risks of Investing in Closed-End Funds. The shares of closed-end funds may trade at a discount or premium to, or at, their NAV. To the extent that the Fund invests a portion of its assets in closed-end funds, those assets will be subject to the risks of the closed-end fund's portfolio securities, and a shareholder in the Fund will bear not only his or her proportionate share of the expenses of the Fund, but also, indirectly, the expenses of the closed-end fund. The securities of closed-end funds in which the Fund may invest may be leveraged. As a result, the Fund may be indirectly exposed to leverage through an investment in such securities. An investment in securities of closed-end funds that use leverage may expose the Fund to higher volatility in the market value of such securities and the possibility that the Fund's long-term returns on such securities (and, indirectly, the long-term returns of the Shares) will be diminished. Risk of Investing in Loans to Non-U.S. Borrowers. The Fund may invest all or a portion of its assets in loans of non-U.S. borrowers. The Fund's investments in loans of non-U.S. borrowers may be affected by political and social instability; changes in economic or taxation policies; difficulties when enforcing obligations; decreased liquidity; and increased volatility. Foreign borrowers may be subject to less regulation resulting in less publicly available information about the borrowers. Sampling Risk. The Fund's use of a representative sampling approach will result in its holding a smaller number of loans than are in the Underlying Index. As a result, an adverse development respecting a borrower of a loan held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the loans in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater. Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. Because the Fund issues and redeems Creation Units for cash, it will incur higher costs in buying and selling securities than if it issued and redeemed Creation Units in-kind. Additionally, the Fund's use of a representative sampling approach may cause the Fund to not be as well correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints. For example, the Fund expects to invest up to 20% of its assets in closed-end funds that, in turn, invest in senior loans, to increase liquidity while providing exposure to senior loans. Cash Transaction Risk. Unlike most exchange-traded funds ("ETFs"), the Fund currently intends to effect creations and redemptions principally for cash, rather than primarily in-kind because of the nature of the Fund's investments. As such, investments in Shares may be less tax efficient than investments in conventional ETFs. Portfolio Turnover Risk. The Fund may engage in frequent trading of its portfolio securities in connection with the rebalancing or adjustment of the Underlying Index. A portfolio turnover rate of 200%, for example, is equivalent to the Fund buying and selling all of its securities two times during the course of a year. A high portfolio turnover rate (such as 100% or more) could result in high brokerage costs for the Fund. A high portfolio turnover rate can result in an increase in taxable capital gains distributions to the Fund's shareholders. Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance. Concentration Risk. A significant percentage of the Underlying Index may be comprised of issuers in a single industry or group of industries. If the Fund is focused in an industry or group of industries, it may present more risks than if it were broadly diversified over numerous industries and groups of industries. The Fund's Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.</pre>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.
