Summary Information

Investment Objective

The PowerShares BulletShares 2018 Corporate Bond Portfolio (the “Fund”) seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an investment grade corporate bond index called the Nasdaq BulletShares ^® USD Corporate Bond 2018 Index (the “2018 Index” or the “Underlying Index”).

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. This example does not include the brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. At the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of the 2018 Index. The 2018 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2017, approximately 346 investment grade corporate bonds with effective maturities in the year 2018. The 2018 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated investment-grade corporate bonds with effective maturities in the year 2018. The effective

3

maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security is determined in accordance with a rules-based methodology developed by Accretive Asset Management, LLC (“Accretive” or the “Index Provider”). The actual maturity of a callable security may change because an issuer of a callable security may “call” or repay the amount owed under the security before its stated maturity. As of the date of this Prospectus, the expected duration of the 2018 Index, and thus of the Fund, is 0.5 to 1 year. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Accretive is affiliated with Invesco PowerShares Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Fund has a designated year of maturity of 2018 and will terminate on or about December 31, 2018. In connection with such termination, the Fund will make a cash distribution to then-current shareholders of its net assets after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount at maturity. The Fund will invest at least 80% of its total assets in component securities that comprise the 2018 Index. In the last six months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2018 without requiring additional approval by the Board of Trustees (the “Board”) of PowerShares Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval if a majority of the Board determines the change to be in the best interest of the Fund. The Board may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Adviser uses quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that resemble the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, sector, duration and other financial characteristics of fixed income instruments. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular Underlying Index components on the performance of the Underlying Index and the availability of particular securities in the secondary market. However, the Fund may use replication to seek to achieve its investment objective if practicable. A replication strategy involves generally investing in all of the securities in the Underlying Index with the same weights as the Underlying Index. There may also be instances when the Adviser may choose to overweight another security in the Underlying Index or purchase (or sell) securities not in the Underlying Index, which the Adviser believes are appropriate to substitute for one or more Underlying Index components in seeking to accurately track the Underlying Index, such as: (i) regulatory requirements possibly affecting the Fund’s ability to hold a security in the Underlying Index or (ii) liquidity concerns possibly affecting the Fund’s ability to purchase or sell a security in the Underlying Index. In addition, from time to time, securities are added to or removed from the Underlying Index. The Fund may sell securities that are represented in the Underlying Index or purchase securities that are not yet represented in the Underlying Index in anticipation of their removal from or addition to the Underlying Index pursuant to scheduled reconstitutions and rebalancings of the Underlying Index. The Fund will concentrate its investments (i.e., invest 25% or more of its assets) in securities issued by companies whose principal business activities are in the same industry or group of industries to the extent the Underlying Index is so concentrated. As of May 31, 2017, the financial sector represented a substantial portion of the Underlying Index.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

4

Asset Class  Risk . The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk . If the Underlying Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries and the Fund’s performance will be particularly susceptible to adverse events impacting such industry.

Credit Risk . The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Declining Yield Risk . During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk . During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk . The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Fluctuation of Yield and Liquidation Amount Risk . The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk . The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include risks associated with differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

Income Risk . The Fund’s income may decline during a period of falling interest rates if the Fund holds floating or variable rate debt securities or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund’s shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk . Investments in fixed-income instruments are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s holdings and share price to decline. The risks

5

associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects on the financial markets and the Fund’s investments. Fixed-income instruments with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk . The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk . It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Adviser for purposes of the Fund’s net asset value (“NAV”), causing the Fund to be less liquid and unable to realize what the Adviser believes should be the price of the investment. Valuation of Fund investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the historically low interest rate environment as of the date of this prospectus.

Market Price Risk . Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk . The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world. The performance of these investments may underperform the general securities markets or other types of securities.

Non-Diversification Risk . The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk . Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Underlying Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Underlying Index.

Prepayment Risk . Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk . U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

6

Risk of Cash Transactions . In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index for a number of reasons, including operating expenses, transaction costs, cash flows and operational inefficiencies. The Fund’s return also may diverge from the return of the Underlying Index because the Fund bears the costs and risks associated with buying and selling securities (especially when rebalancing the Fund’s securities holdings to reflect changes in the Underlying Index) while such costs and risks are not factored into the return of the Underlying Index. Transaction costs, including brokerage costs, will decrease the Fund’s NAV to the extent not offset by the transaction fee payable by an Authorized Participant. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. In addition, the Fund’s use of a representative sampling approach may cause the Fund’s returns 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. Errors in the Underlying Index data, the Underlying Index computations and/or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. In addition, the Fund may be unable to invest in certain securities included in the Underlying Index, or invest in them in the exact proportions in which they are represented in the Underlying Index, due to legal restrictions or limitations imposed by the governments of certain countries, a lack of liquidity in markets in which such securities trade, potential adverse tax consequences or other regulatory reasons. To the extent the Fund calculates its NAV based on fair value prices and the value of the Underlying Index is based on the securities’ closing prices (i.e., the value of the Underlying Index is not based on fair value prices), the Fund’s ability to track the Underlying Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities, and such sale may cause the Fund to realize a loss and, thus, the Fund’s performance to deviate from the performance of the Underlying Index. In light of the factors discussed above, the Fund’s return may deviate significantly from the return of the Underlying Index.

Performance

As of the date of this Prospectus, the Fund has not commenced operations and therefore does not have a performance history. Once available, the Fund’s performance information will be accessible on the Fund’s website at www.powershares.com and will provide some indication of the risks of investing in the Fund.

7

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only with APs and only in large blocks of 150,000 Shares (each block of Shares is called a “Creation Unit”), or multiples thereof (“Creation Unit Aggregations”), in exchange for the deposit or delivery of a basket of securities and/or cash. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares may be purchased and sold only on a national securities exchange through brokers. Shares will be listed for trading on NYSE Arca, Inc. (the “Exchange”) and because the Shares will trade at market prices rather than NAV, Shares may trade at prices greater than NAV (at a premium), at NAV, or less than NAV (at a discount).

Tax Information

The Fund’s distributions will generally be taxable, typically as either ordinary income or long-term capital gain, unless you are invested through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account; in such cases, taxation will be deferred until assets are withdrawn from the plan. A sale of Shares may result in short- or long-term capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund’s distributor or its related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary’s web-site for more information.

Summary Information

Investment Objective

The PowerShares BulletShares 2019 Corporate Bond Portfolio (the “Fund”) seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an investment grade corporate bond index called the Nasdaq BulletShares ^® USD Corporate Bond 2019 Index (the “2019 Index” or the “Underlying Index”).

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. This example does not include the brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. At the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of the 2019 Index. The 2019 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2017, approximately 380 investment grade corporate bonds with effective maturities in the year 2019. The 2019 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated investment-grade corporate bonds with effective maturities in the year 2019. The effective

9

maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security is determined in accordance with a rules-based methodology developed by Accretive Asset Management, LLC (“Accretive” or the “Index Provider”). The actual maturity of a callable security may change because an issuer of a callable security may “call” or repay the amount owed under the security before its stated maturity. As of the date of this Prospectus, the expected duration of the 2019 Index, and thus of the Fund, is 1 to 2 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Accretive is affiliated with Invesco PowerShares Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Fund has a designated year of maturity of 2019 and will terminate on or about December 31, 2019. In connection with such termination, the Fund will make a cash distribution to then-current shareholders of its net assets after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount at maturity. The Fund will invest at least 80% of its total assets in component securities that comprise the 2019 Index. In the last six months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2019 without requiring additional approval by the Board of Trustees (the “Board”) of PowerShares Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval if a majority of the Board determines the change to be in the best interest of the Fund. The Board may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Adviser uses quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that resemble the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, sector, duration and other financial characteristics of fixed income instruments. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular Underlying Index components on the performance of the Underlying Index and the availability of particular securities in the secondary market. However, the Fund may use replication to seek to achieve its investment objective if practicable. A replication strategy involves generally investing in all of the securities in the Underlying Index with the same weights as the Underlying Index. There may also be instances when the Adviser may choose to overweight another security in the Underlying Index or purchase (or sell) securities not in the Underlying Index, which the Adviser believes are appropriate to substitute for one or more Underlying Index components in seeking to accurately track the Underlying Index, such as: (i) regulatory requirements possibly affecting the Fund’s ability to hold a security in the Underlying Index or (ii) liquidity concerns possibly affecting the Fund’s ability to purchase or sell a security in the Index. In addition, from time to time, securities are added to or removed from the Underlying Index. The Fund may sell securities that are represented in the Underlying Index or purchase securities that are not yet represented in the Underlying Index in anticipation of their removal from or addition to the Underlying Index pursuant to scheduled reconstitutions and rebalancings of the Underlying Index. The Fund will concentrate its investments (i.e., invest 25% or more of its assets) in securities issued by companies whose principal business activities are in the same industry or group of industries to the extent the Underlying Index is so concentrated. As of May 31, 2017, the financial and consumer staples sectors each represented a substantial portion of the Underlying Index.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

10

Asset Class  Risk . The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk . If the Underlying Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries and the Fund’s performance will be particularly susceptible to adverse events impacting such industry.

Consumer Staples Sector Risk . Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk . The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Declining Yield Risk . During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk . During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk . The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Fluctuation of Yield and Liquidation Amount Risk . The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk . The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include risks associated with differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

Income Risk . The Fund’s income may decline during a period of falling interest rates if the Fund holds floating or variable rate debt securities or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund’s shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

11

Interest Rate Risk. Investments in fixed-income instruments are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s holdings and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects on the financial markets and the Fund’s investments. Fixed-income instruments with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk . The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk . It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Adviser for purposes of the Fund’s net asset value (“NAV”), causing the Fund to be less liquid and unable to realize what the Adviser believes should be the price of the investment. Valuation of Fund investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the historically low interest rate environment as of the date of this prospectus.

Market Price Risk . Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk . The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world. The performance of these investments may underperform the general securities markets or other types of securities.

Non-Diversification Risk . The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk . Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Underlying Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Underlying Index.

Prepayment Risk . Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk . U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

12

Risk of Cash Transactions . In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Tracking Error Risk . The performance of the Fund may diverge from that of the Underlying Index for a number of reasons, including operating expenses, transaction costs, cash flows and operational inefficiencies. The Fund’s return also may diverge from the return of the Underlying Index because the Fund bears the costs and risks associated with buying and selling securities (especially when rebalancing the Fund’s securities holdings to reflect changes in the Underlying Index) while such costs and risks are not factored into the return of the Underlying Index. Transaction costs, including brokerage costs, will decrease the Fund’s NAV to the extent not offset by the transaction fee payable by an Authorized Participant. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. In addition, the Fund’s use of a representative sampling approach may cause the Fund’s returns 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. Errors in the Underlying Index data, the Underlying Index computations and/or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. In addition, the Fund may be unable to invest in certain securities included in the Underlying Index, or invest in them in the exact proportions in which they are represented in the Underlying Index, due to legal restrictions or limitations imposed by the governments of certain countries, a lack of liquidity in markets in which such securities trade, potential adverse tax consequences or other regulatory reasons. To the extent the Fund calculates its NAV based on fair value prices and the value of the Underlying Index is based on the securities’ closing prices (i.e., the value of the Underlying Index is not based on fair value prices), the Fund’s ability to track the Underlying Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities, and such sale may cause the Fund to realize a loss and, thus, the Fund’s performance to deviate from the performance of the Underlying Index. In light of the factors discussed above, the Fund’s return may deviate significantly from the return of the Underlying Index.

Performance

As of the date of this Prospectus, the Fund has not commenced operations and therefore does not have a performance history. Once available, the Fund’s performance information will be accessible on the Fund’s website at www.powershares.com and will provide some indication of the risks of investing in the Fund.

13

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only with APs and only in large blocks of 150,000 Shares (each block of Shares is called a “Creation Unit”), or multiples thereof (“Creation Unit Aggregations”), in exchange for the deposit or delivery of a basket of securities and/or cash. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares may be purchased and sold only on a national securities exchange through brokers. Shares will be listed for trading on NYSE Arca, Inc. (the “Exchange”) and because the Shares will trade at market prices rather than NAV, Shares may trade at prices greater than NAV (at a premium), at NAV, or less than NAV (at a discount).

Tax Information

The Fund’s distributions will generally be taxable, typically as either ordinary income or long-term capital gain, unless you are invested through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account; in such cases, taxation will be deferred until assets are withdrawn from the plan. A sale of Shares may result in short- or long-term capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund’s distributor or its related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary’s web-site for more information.

Summary Information

Investment Objective

The PowerShares BulletShares 2020 Corporate Bond Portfolio (the “Fund”) seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an investment grade corporate bond index called the Nasdaq BulletShares ^® USD Corporate Bond 2020 Index (the “2020 Index” or the “Underlying Index”).

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. This example does not include the brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. At the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of the 2020 Index. The 2020 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2017, approximately 348 investment grade corporate bonds with effective maturities in the year 2020. The 2020 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated investment-grade corporate bonds with effective maturities in the year 2020. The effective

15

maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security is determined in accordance with a rules-based methodology developed by Accretive Asset Management, LLC (“Accretive” or the “Index Provider”). The actual maturity of a callable security may change because an issuer of a callable security may “call” or repay the amount owed under the security before its stated maturity. As of the date of this Prospectus, the expected duration of the 2020 Index, and thus of the Fund, is 1 to 3 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Accretive is affiliated with Invesco PowerShares Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Fund has a designated year of maturity of 2020 and will terminate on or about December 31, 2020. In connection with such termination, the Fund will make a cash distribution to then-current shareholders of its net assets after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount at maturity. The Fund will invest at least 80% of its total assets in component securities that comprise the 2020 Index. In the last six months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2020 without requiring additional approval by the Board of Trustees (the “Board”) of PowerShares Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval if a majority of the Board determines the change to be in the best interest of the Fund. The Board may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Adviser uses quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that resemble the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, sector, duration and other financial characteristics of fixed income instruments. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular Underlying Index components on the performance of the Underlying Index and the availability of particular securities in the secondary market. However, the Fund may use replication to seek to achieve its investment objective if practicable. A replication strategy involves generally investing in all of the securities in the Underlying Index with the same weights as the Underlying Index. There may also be instances when the Adviser may choose to overweight another security in the Underlying Index or purchase (or sell) securities not in the Underlying Index, which the Adviser believes are appropriate to substitute for one or more Underlying Index components in seeking to accurately track the Underlying Index, such as: (i) regulatory requirements possibly affecting the Fund’s ability to hold a security in the Underlying Index or (ii) liquidity concerns possibly affecting the Fund’s ability to purchase or sell a security in the Underlying Index. In addition, from time to time, securities are added to or removed from the Underlying Index. The Fund may sell securities that are represented in the Underlying Index or purchase securities that are not yet represented in the Underlying Index in anticipation of their removal from or addition to the Underlying Index pursuant to scheduled reconstitutions and rebalancings of the Underlying Index. The Fund will concentrate its investments (i.e., invest 25% or more of its assets) in securities issued by companies whose principal business activities are in the same industry or group of industries to the extent the Underlying Index is so concentrated. As of May 31, 2017, the financial and consumer staples sectors each represented a substantial portion of the Underlying Index.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

16

Asset Class  Risk . The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk . If the Underlying Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries and the Fund’s performance will be particularly susceptible to adverse events impacting such industry.

Consumer Staples Sector Risk . Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk . The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Declining Yield Risk . During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk . During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk . The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Fluctuation of Yield and Liquidation Amount Risk . The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk . The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include risks associated with differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

17

Income Risk . The Fund’s income may decline during a period of falling interest rates if the Fund holds floating or variable rate debt securities or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund’s shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk . Investments in fixed-income instruments are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s holdings and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects on the financial markets and the Fund’s investments. Fixed-income instruments with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk . The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk . It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Adviser for purposes of the Fund’s net asset value (“NAV”), causing the Fund to be less liquid and unable to realize what the Adviser believes should be the price of the investment. Valuation of Fund investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the historically low interest rate environment as of the date of this prospectus.

Market Price Risk . Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk . The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world. The performance of these investments may underperform the general securities markets or other types of securities.

Non-Diversification Risk . The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk . Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Underlying Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Underlying Index.

Prepayment Risk . Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

18

Regulatory and Legal Risk . U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

Risk of Cash Transactions . In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Tracking Error Risk . The performance of the Fund may diverge from that of the Underlying Index for a number of reasons, including operating expenses, transaction costs, cash flows and operational inefficiencies. The Fund’s return also may diverge from the return of the Underlying Index because the Fund bears the costs and risks associated with buying and selling securities (especially when rebalancing the Fund’s securities holdings to reflect changes in the Underlying Index) while such costs and risks are not factored into the return of the Underlying Index. Transaction costs, including brokerage costs, will decrease the Fund’s NAV to the extent not offset by the transaction fee payable by an Authorized Participant. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. In addition, the Fund’s use of a representative sampling approach may cause the Fund’s returns 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. Errors in the Underlying Index data, the Underlying Index computations and/or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. In addition, the Fund may be unable to invest in certain securities included in the Underlying Index, or invest in them in the exact proportions in which they are represented in the Underlying Index, due to legal restrictions or limitations imposed by the governments of certain countries, a lack of liquidity in markets in which such securities trade, potential adverse tax consequences or other regulatory reasons. To the extent the Fund calculates its NAV based on fair value prices and the value of the Underlying Index is based on the securities’ closing prices (i.e., the value of the Underlying Index is not based on fair value prices), the Fund’s ability to track the Underlying Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities, and such sale may cause the Fund to realize a loss and, thus, the Fund’s performance to deviate from the performance of the Underlying Index. In light of the factors discussed above, the Fund’s return may deviate significantly from the return of the Underlying Index.

Once available, the Fund’s performance information will be accessible on the Fund’s website at www.powershares.com and will provide some indication of the risks of investing in the Fund.

19

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only with APs and only in large blocks of 150,000 Shares (each block of Shares is called a “Creation Unit”), or multiples thereof (“Creation Unit Aggregations”), in exchange for the deposit or delivery of a basket of securities and/or cash. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares may be purchased and sold only on a national securities exchange through brokers. Shares will be listed for trading on NYSE Arca, Inc. (the “Exchange”) and because the Shares will trade at market prices rather than NAV, Shares may trade at prices greater than NAV (at a premium), at NAV, or less than NAV (at a discount).

Tax Information

The Fund’s distributions will generally be taxable, typically as either ordinary income or long-term capital gain, unless you are invested through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account; in such cases, taxation will be deferred until assets are withdrawn from the plan. A sale of Shares may result in short- or long-term capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund’s distributor or its related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary’s web-site for more information.

Summary Information

Investment Objective

The PowerShares BulletShares 2021 Corporate Bond Portfolio (the “Fund”) seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an investment grade corporate bond index called the Nasdaq BulletShares ^® USD Corporate Bond 2021 Index (the “2021 Index” or the “Underlying Index”).

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. This example does not include the brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. At the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of the 2021 Index. The 2021 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2017, approximately 365 investment grade corporate bonds with effective maturities in the year 2021. The 2021 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated investment-grade corporate bonds with effective maturities in the year 2021. The effective

21

maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security is determined in accordance with a rules-based methodology developed by Accretive Asset Management, LLC (“Accretive” or the “Index Provider”). The actual maturity of a callable security may change because an issuer of a callable security may “call” or repay the amount owed under the security before its stated maturity. As of the date of this Prospectus, the expected duration of the 2021 Index, and thus of the Fund, is 2 to 4 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Accretive is affiliated with Invesco PowerShares Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Fund has a designated year of maturity of 2021 and will terminate on or about December 31, 2021. In connection with such termination, the Fund will make a cash distribution to then-current shareholders of its net assets after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount at maturity. The Fund will invest at least 80% of its total assets in component securities that comprise the 2021 Index. In the last six months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2021 without requiring additional approval by the Board of Trustees (the “Board”) of PowerShares Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval if a majority of the Board determines the change to be in the best interest of the Fund. The Board may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Adviser uses quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that resemble the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, sector, duration and other financial characteristics of fixed income instruments. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular Underlying Index components on the performance of the Underlying Index and the availability of particular securities in the secondary market. However, the Fund may use replication to seek to achieve its investment objective if practicable.

The Fund may sell securities that are represented in the Underlying Index or purchase securities that are not yet represented in the Underlying Index in anticipation of their removal from or addition to the Underlying Index pursuant to scheduled reconstitutions and rebalancings of the Underlying Index. The Fund will concentrate its investments (i.e., invest 25% or more of its assets) in securities issued by companies whose principal business activities are in the same industry or group of industries to the extent the Underlying Index is so concentrated. As of May 31, 2017, the financial and consumer staples sectors each represented a substantial portion of the Underlying Index.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

22

Asset Class  Risk . The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk . If the Underlying Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries and the Fund’s performance will be particularly susceptible to adverse events impacting such industry.

Consumer Staples Sector Risk . Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk . The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Declining Yield Risk . During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk . During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk . The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Fluctuation of Yield and Liquidation Amount Risk . The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk. The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include risks associated with differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

Income Risk . The Fund’s income may decline during a period of falling interest rates if the Fund holds floating or variable rate debt securities or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund’s shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

23

Interest Rate Risk . Investments in fixed-income instruments are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s holdings and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects on the financial markets and the Fund’s investments. Fixed-income instruments with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk . The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk . It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Adviser for purposes of the Fund’s net asset value (“NAV”), causing the Fund to be less liquid and unable to realize what the Adviser believes should be the price of the investment. Valuation of Fund investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the historically low interest rate environment as of the date of this prospectus.

Market Price Risk . Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk . The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world. The performance of these investments may underperform the general securities markets or other types of securities.

Non-Diversification Risk . The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk . Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Underlying Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Underlying Index.

Prepayment Risk . Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk . U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

24

Risk of Cash Transactions . In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Tracking Error Risk . The performance of the Fund may diverge from that of the Underlying Index for a number of reasons, including operating expenses, transaction costs, cash flows and operational inefficiencies. The Fund’s return also may diverge from the return of the Underlying Index because the Fund bears the costs and risks associated with buying and selling securities (especially when rebalancing the Fund’s securities holdings to reflect changes in the Underlying Index) while such costs and risks are not factored into the return of the Underlying Index. Transaction costs, including brokerage costs, will decrease the Fund’s NAV to the extent not offset by the transaction fee payable by an Authorized Participant. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. In addition, the Fund’s use of a representative sampling approach may cause the Fund’s returns 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. Errors in the Underlying Index data, the Underlying Index computations and/or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. In addition, the Fund may be unable to invest in certain securities included in the Underlying Index, or invest in them in the exact proportions in which they are represented in the Underlying Index, due to legal restrictions or limitations imposed by the governments of certain countries, a lack of liquidity in markets in which such securities trade, potential adverse tax consequences or other regulatory reasons. To the extent the Fund calculates its NAV based on fair value prices and the value of the Underlying Index is based on the securities’ closing prices (i.e., the value of the Underlying Index is not based on fair value prices), the Fund’s ability to track the Underlying Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities, and such sale may cause the Fund to realize a loss and, thus, the Fund’s performance to deviate from the performance of the Underlying Index. In light of the factors discussed above, the Fund’s return may deviate significantly from the return of the Underlying Index.

Performance

As of the date of this Prospectus, the Fund has not commenced operations and therefore does not have a performance history. Once available, the Fund’s performance information will be accessible on the Fund’s website at www.powershares.com and will provide some indication of the risks of investing in the Fund.

25

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only with APs and only in large blocks of 150,000 Shares (each block of Shares is called a “Creation Unit”), or multiples thereof (“Creation Unit Aggregations”), in exchange for the deposit or delivery of a basket of securities and/or cash. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares may be purchased and sold only on a national securities exchange through brokers. Shares will be listed for trading on NYSE Arca, Inc. (the “Exchange”) and because the Shares will trade at market prices rather than NAV, Shares may trade at prices greater than NAV (at a premium), at NAV, or less than NAV (at a discount).

Tax Information

The Fund’s distributions will generally be taxable, typically as either ordinary income or long-term capital gain, unless you are invested through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account; in such cases, taxation will be deferred until assets are withdrawn from the plan. A sale of Shares may result in short- or long-term capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund’s distributor or its related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary’s web-site for more information.

Summary Information

Investment Objective

The PowerShares BulletShares 2022 Corporate Bond Portfolio (the “Fund”) seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an investment grade corporate bond index called the Nasdaq BulletShares ^® USD Corporate Bond 2022 Index (the “2022 Index” or the “Underlying Index”).

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. This example does not include the brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. At the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of the 2022 Index. The 2022 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2017, approximately 333 investment grade corporate bonds with effective maturities in the year 2022. The 2022 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated investment-grade corporate bonds with effective maturities in the year 2022. The effective

27

maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security is determined in accordance with a rules-based methodology developed by Accretive Asset Management, LLC (“Accretive” or the “Index Provider”). The actual maturity of a callable security may change because an issuer of a callable security may “call” or repay the amount owed under the security before its stated maturity. As of the date of this Prospectus, the expected duration of the 2022 Index, and thus of the Fund, is 3 to 5 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Accretive is affiliated with Invesco PowerShares Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Fund has a designated year of maturity of 2022 and will terminate on or about December 31, 2022. In connection with such termination, the Fund will make a cash distribution to then-current shareholders of its net assets after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount at maturity. The Fund will invest at least 80% of its total assets in component securities that comprise the 2022 Index. In the last six months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2022 without requiring additional approval by the Board of Trustees (the “Board”) of PowerShares Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval if a majority of the Board determines the change to be in the best interest of the Fund. The Board may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Adviser uses quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that resemble the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, sector, duration and other financial characteristics of fixed income instruments. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular Underlying Index components on the performance of the Underlying Index and the availability of particular securities in the secondary market. However, the Fund may use replication to seek to achieve its investment objective if practicable. A replication strategy involves generally investing in all of the securities in the Underlying Index with the same weights as the Underlying Index. There may also be instances when the Adviser may choose to overweight another security in the Underlying Index or purchase (or sell) securities not in the Underlying Index, which the Adviser believes are appropriate to substitute for one or more Underlying Index components in seeking to accurately track the Underlying Index, such as: (i) regulatory requirements possibly affecting the Fund’s ability to hold a security in the Underlying Index or (ii) liquidity concerns possibly affecting the Fund’s ability to purchase or sell a security in the Underlying Index. In addition, from time to time, securities are added to or removed from the Underlying Index. The Fund may sell securities that are represented in the Underlying Index or purchase securities that are not yet represented in the Underlying Index in anticipation of their removal from or addition to the Underlying Index pursuant to scheduled reconstitutions and rebalancings of the Underlying Index. The Fund will concentrate its investments (i.e., invest 25% or more of its assets) in securities issued by companies whose principal business activities are in the same industry or group of industries to the extent the Underlying Index is so concentrated. As of May 31, 2017, the financial and consumer staples sectors each represented a substantial portion of the Underlying Index.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

28

Asset Class  Risk . The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk . If the Underlying Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries and the Fund’s performance will be particularly susceptible to adverse events impacting such industry.

Consumer Staples Sector Risk . Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk . The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Declining Yield Risk . During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk . During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk . The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Fluctuation of Yield and Liquidation Amount Risk . The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk . The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include risks associated with differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

Income Risk . The Fund’s income may decline during a period of falling interest rates if the Fund holds floating or variable rate debt securities or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund’s shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

29

Interest Rate Risk . Investments in fixed-income instruments are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s holdings and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects on the financial markets and the Fund’s investments. Fixed-income instruments with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk . It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Adviser for purposes of the Fund’s net asset value (“NAV”), causing the Fund to be less liquid and unable to realize what the Adviser believes should be the price of the investment. Valuation of Fund investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the historically low interest rate environment as of the date of this prospectus.

Market Price Risk . Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk . The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world. The performance of these investments may underperform the general securities markets or other types of securities.

Non-Diversification Risk . The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk . Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Underlying Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Underlying Index.

Prepayment Risk . Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk . U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

30

Risk of Cash Transactions . In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Tracking Error Risk . The performance of the Fund may diverge from that of the Underlying Index for a number of reasons, including operating expenses, transaction costs, cash flows and operational inefficiencies. The Fund’s return also may diverge from the return of the Underlying Index because the Fund bears the costs and risks associated with buying and selling securities (especially when rebalancing the Fund’s securities holdings to reflect changes in the Underlying Index) while such costs and risks are not factored into the return of the Underlying Index. Transaction costs, including brokerage costs, will decrease the Fund’s NAV to the extent not offset by the transaction fee payable by an Authorized Participant. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. In addition, the Fund’s use of a representative sampling approach may cause the Fund’s returns 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. Errors in the Underlying Index data, the Underlying Index computations and/or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. In addition, the Fund may be unable to invest in certain securities included in the Underlying Index, or invest in them in the exact proportions in which they are represented in the Underlying Index, due to legal restrictions or limitations imposed by the governments of certain countries, a lack of liquidity in markets in which such securities trade, potential adverse tax consequences or other regulatory reasons. To the extent the Fund calculates its NAV based on fair value prices and the value of the Underlying Index is based on the securities’ closing prices (i.e., the value of the Underlying Index is not based on fair value prices), the Fund’s ability to track the Underlying Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities, and such sale may cause the Fund to realize a loss and, thus, the Fund’s performance to deviate from the performance of the Underlying Index. In light of the factors discussed above, the Fund’s return may deviate significantly from the return of the Underlying Index.

Performance

As of the date of this Prospectus, the Fund has not commenced operations and therefore does not have a performance history. Once available, the Fund’s performance information will be accessible on the Fund’s website at www.powershares.com and will provide some indication of the risks of investing in the Fund.

31

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only with APs and only in large blocks of 150,000 Shares (each block of Shares is called a “Creation Unit”), or multiples thereof (“Creation Unit Aggregations”), in exchange for the deposit or delivery of a basket of securities and/or cash. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares may be purchased and sold only on a national securities exchange through brokers. Shares will be listed for trading on NYSE Arca, Inc. (the “Exchange”) and because the Shares will trade at market prices rather than NAV, Shares may trade at prices greater than NAV (at a premium), at NAV, or less than NAV (at a discount).

Tax Information

The Fund’s distributions will generally be taxable, typically as either ordinary income or long-term capital gain, unless you are invested through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account; in such cases, taxation will be deferred until assets are withdrawn from the plan. A sale of Shares may result in short- or long-term capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund’s distributor or its related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary’s web-site for more information.

Summary Information

Investment Objective

The PowerShares BulletShares 2023 Corporate Bond Portfolio (the “Fund”) seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an investment grade corporate bond index called the Nasdaq BulletShares ^® USD Corporate Bond 2023 Index (the “2023 Index” or the “Underlying Index”).

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. This example does not include the brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. At the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of the 2023 Index. The 2023 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2017, approximately 230 investment grade corporate bonds with effective maturities in the year 2023. The 2023 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated investment-grade corporate bonds with effective maturities in the year 2023. The effective

33

maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security is determined in accordance with a rules-based methodology developed by Accretive Asset Management, LLC (“Accretive” or the “Index Provider”). The actual maturity of a callable security may change because an issuer of a callable security may “call” or repay the amount owed under the security before its stated maturity. As of the date of this Prospectus, the expected duration of the 2023 Index, and thus of the Fund, is 4 to 6 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Accretive is affiliated with Invesco PowerShares Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Fund has a designated year of maturity of 2023 and will terminate on or about December 31, 2023. In connection with such termination, the Fund will make a cash distribution to then-current shareholders of its net assets after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount at maturity. The Fund will invest at least 80% of its total assets in component securities that comprise the 2023 Index. In the last six months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2023 without requiring additional approval by the Board of Trustees (the “Board”) of PowerShares Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval if a majority of the Board determines the change to be in the best interest of the Fund. The Board may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Adviser uses quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that resemble the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, sector, duration and other financial characteristics of fixed income instruments. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular Underlying Index components on the performance of the Underlying Index and the availability of particular securities in the secondary market. However, the Fund may use replication to seek to achieve its investment objective if practicable. A replication strategy involves generally investing in all of the securities in the Underlying Index with the same weights as the Underlying Index. There may also be instances when the Adviser may choose to overweight another security in the Underlying Index or purchase (or sell) securities not in the Underlying Index, which the Adviser believes are appropriate to substitute for one or more Underlying Index components in seeking to accurately track the Underlying Index, such as: (i) regulatory requirements possibly affecting the Fund’s ability to hold a security in the Underlying Index or (ii) liquidity concerns possibly affecting the Fund’s ability to purchase or sell a security in the Underlying Index. In addition, from time to time, securities are added to or removed from the Underlying Index. The Fund may sell securities that are represented in the Underlying Index or purchase securities that are not yet represented in the Underlying Index in anticipation of their removal from or addition to the Underlying Index pursuant to scheduled reconstitutions and rebalancings of the Underlying Index. The Fund will concentrate its investments (i.e., invest 25% or more of its assets) in securities issued by companies whose principal business activities are in the same industry or group of industries to the extent the Underlying Index is so concentrated. As of May 31, 2017, the financial and consumer staples sectors each represented a substantial portion of the Underlying Index.

Asset Class  Risk . The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk . If the Underlying Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries and the Fund’s performance will be particularly susceptible to adverse events impacting such industry.

Consumer Staples Sector Risk . Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk . The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Declining Yield Risk . During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk . During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk . The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Fluctuation of Yield and Liquidation Amount Risk . The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk . The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include risks associated with differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

35

Income Risk . The Fund’s income may decline during a period of falling interest rates if the Fund holds floating or variable rate debt securities or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund’s shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk . Investments in fixed-income instruments are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s holdings and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects on the financial markets and the Fund’s investments. Fixed-income instruments with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk . The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk . It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Adviser for purposes of the Fund’s net asset value (“NAV”), causing the Fund to be less liquid and unable to realize what the Adviser believes should be the price of the investment. Valuation of Fund investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the historically low interest rate environment as of the date of this prospectus.

Market Price Risk . Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk . The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world. The performance of these investments may underperform the general securities markets or other types of securities.

Non-Diversification Risk . The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk . Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Underlying Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Underlying Index.

Prepayment Risk . Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

36

Regulatory and Legal Risk . U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

Risk of Cash Transactions . In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Tracking Error Risk . The performance of the Fund may diverge from that of the Underlying Index for a number of reasons, including operating expenses, transaction costs, cash flows and operational inefficiencies. The Fund’s return also may diverge from the return of the Underlying Index because the Fund bears the costs and risks associated with buying and selling securities (especially when rebalancing the Fund’s securities holdings to reflect changes in the Underlying Index) while such costs and risks are not factored into the return of the Underlying Index. Transaction costs, including brokerage costs, will decrease the Fund’s NAV to the extent not offset by the transaction fee payable by an Authorized Participant. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. In addition, the Fund’s use of a representative sampling approach may cause the Fund’s returns 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. Errors in the Underlying Index data, the Underlying Index computations and/or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. In addition, the Fund may be unable to invest in certain securities included in the Underlying Index, or invest in them in the exact proportions in which they are represented in the Underlying Index, due to legal restrictions or limitations imposed by the governments of certain countries, a lack of liquidity in markets in which such securities trade, potential adverse tax consequences or other regulatory reasons. To the extent the Fund calculates its NAV based on fair value prices and the value of the Underlying Index is based on the securities’ closing prices (i.e., the value of the Underlying Index is not based on fair value prices), the Fund’s ability to track the Underlying Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities, and such sale may cause the Fund to realize a loss and, thus, the Fund’s performance to deviate from the performance of the Underlying Index. In light of the factors discussed above, the Fund’s return may deviate significantly from the return of the Underlying Index.

Performance

As of the date of this Prospectus, the Fund has not commenced operations and therefore does not have a performance history. Once available, the Fund’s performance information will be accessible on the Fund’s website at www.powershares.com and will provide some indication of the risks of investing in the Fund.

37

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only with APs and only in large blocks of 150,000 Shares (each block of Shares is called a “Creation Unit”), or multiples thereof (“Creation Unit Aggregations”), in exchange for the deposit or delivery of a basket of securities and/or cash. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares may be purchased and sold only on a national securities exchange through brokers. Shares will be listed for trading on NYSE Arca, Inc. (the “Exchange”) and because the Shares will trade at market prices rather than NAV, Shares may trade at prices greater than NAV (at a premium), at NAV, or less than NAV (at a discount).

Tax Information

The Fund’s distributions will generally be taxable, typically as either ordinary income or long-term capital gain, unless you are invested through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account; in such cases, taxation will be deferred until assets are withdrawn from the plan. A sale of Shares may result in short- or long-term capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund’s distributor or its related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary’s web-site for more information.

Summary Information

Investment Objective

The PowerShares BulletShares 2024 Corporate Bond Portfolio (the “Fund”) seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an investment grade corporate bond index called the Nasdaq BulletShares ^® USD Corporate Bond 2024 Index (the “2024 Index” or the “Underlying Index”).

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. This example does not include the brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. At the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of the 2024 Index. The 2024 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2017, approximately 219 investment grade corporate bonds with effective maturities in the year 2024. The 2024 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated investment-grade corporate bonds with effective maturities in the year 2024. The effective

39

maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security is determined in accordance with a rules-based methodology developed by Accretive Asset Management, LLC (“Accretive” or the “Index Provider”). The actual maturity of a callable security may change because an issuer of a callable security may “call” or repay the amount owed under the security before its stated maturity. As of the date of this Prospectus, the expected duration of the 2024 Index, and thus of the Fund, is 5 to 7 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Accretive is affiliated with Invesco PowerShares Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Fund has a designated year of maturity of 2024 and will terminate on or about December 31, 2024. In connection with such termination, the Fund will make a cash distribution to then-current shareholders of its net assets after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount at maturity. The Fund will invest at least 80% of its total assets in component securities that comprise the 2024 Index. In the last six months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2024 without requiring additional approval by the Board of Trustees (the “Board”) of PowerShares Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval if a majority of the Board determines the change to be in the best interest of the Fund. The Board may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Adviser uses quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that resemble the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, sector, duration and other financial characteristics of fixed income instruments. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular Underlying Index components on the performance of the Underlying Index and the availability of particular securities in the secondary market. However, the Fund may use replication to seek to achieve its investment objective if practicable. A replication strategy involves generally investing in all of the securities in the Underlying Index with the same weights as the Underlying Index. There may also be instances when the Adviser may choose to overweight another security in the Underlying Index or purchase (or sell) securities not in the Underlying Index, which the Adviser believes are appropriate to substitute for one or more Underlying Index components in seeking to accurately track the Underlying Index, such as: (i) regulatory requirements possibly affecting the Fund’s ability to hold a security in the Underlying Index or (ii) liquidity concerns possibly affecting the Fund’s ability to purchase or sell a security in the Underlying Index. In addition, from time to time, securities are added to or removed from the Underlying Index. The Fund may sell securities that are represented in the Underlying Index or purchase securities that are not yet represented in the Underlying Index in anticipation of their removal from or addition to the Underlying Index pursuant to scheduled reconstitutions and rebalancings of the Underlying Index. The Fund will concentrate its investments (i.e., invest 25% or more of its assets) in securities issued by companies whose principal business activities are in the same industry or group of industries to the extent the Underlying Index is so concentrated. As of May 31, 2017, the financial and energy sectors each represented a substantial portion of the Underlying Index.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

40

Asset Class  Risk . The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk . If the Underlying Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries and the Fund’s performance will be particularly susceptible to adverse events impacting such industry.

Credit Risk . The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Declining Yield Risk . During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Energy Sector Risk . The energy sector is often cyclical and highly dependent on commodities prices. Securities prices for companies in the energy sector may be affected by a variety of factors, including, among others, worldwide energy prices, exploration costs, energy conservation efforts, changes in currency exchange rates, government regulation and market, economic and political risks of the countries where energy companies are located or do business. The Fund may be adversely affected by negative developments relating to the energy sector and commodities issuers.

Extension Risk . During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk . The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Fluctuation of Yield and Liquidation Amount Risk . The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk . The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include risks associated with differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

Income Risk . The Fund’s income may decline during a period of falling interest rates if the Fund holds floating or variable rate debt securities or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund’s shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

41

Interest Rate Risk . Investments in fixed-income instruments are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s holdings and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects on the financial markets and the Fund’s investments. Fixed-income instruments with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk . The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk . It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Adviser for purposes of the Fund’s net asset value (“NAV”), causing the Fund to be less liquid and unable to realize what the Adviser believes should be the price of the investment. Valuation of Fund investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the historically low interest rate environment as of the date of this prospectus.

Market Price Risk . Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk . The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world. The performance of these investments may underperform the general securities markets or other types of securities.

Non-Diversification Risk . The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Underlying Index.

Prepayment Risk. Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk . U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

42

Risk of Cash Transactions . In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Tracking Error Risk . The performance of the Fund may diverge from that of the Underlying Index for a number of reasons, including operating expenses, transaction costs, cash flows and operational inefficiencies. The Fund’s return also may diverge from the return of the Underlying Index because the Fund bears the costs and risks associated with buying and selling securities (especially when rebalancing the Fund’s securities holdings to reflect changes in the Underlying Index) while such costs and risks are not factored into the return of the Underlying Index.

For tax efficiency purposes, the Fund may sell certain securities, and such sale may cause the Fund to realize a loss and, thus, the Fund’s performance to deviate from the performance of the Underlying Index. In light of the factors discussed above, the Fund’s return may deviate significantly from the return of the Underlying Index.

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only with APs and only in large blocks of 150,000 Shares (each block of Shares is called a “Creation Unit”), or multiples thereof (“Creation Unit Aggregations”), in exchange for the deposit or delivery of a basket of securities and/or cash.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund’s distributor or its related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment.

Summary Information

Investment Objective

The PowerShares BulletShares 2025 Corporate Bond Portfolio (the “Fund”) seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an investment grade corporate bond index called the Nasdaq BulletShares ^® USD Corporate Bond 2025 Index (the “2025 Index” or the “Underlying Index”).

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. This example does not include the brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. At the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of the 2025 Index. The 2025 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2017, approximately 200 investment grade corporate bonds with effective maturities in the year 2025. The 2025 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated investment-grade corporate bonds with effective maturities in the year 2025. The effective

maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security is determined in accordance with a rules-based methodology developed by Accretive Asset Management, LLC (“Accretive” or the “Index Provider”). The actual maturity of a callable security may change because an issuer of a callable security may “call” or repay the amount owed under the security before its stated maturity. As of the date of this Prospectus, the expected duration of the 2025 Index, and thus of the Fund, is 6 to 8 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Accretive is affiliated with Invesco PowerShares Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Fund has a designated year of maturity of 2025 and will terminate on or about December 31, 2025. In connection with such termination, the Fund will make a cash distribution to then-current shareholders of its net assets after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount at maturity. The Fund will invest at least 80% of its total assets in component securities that comprise the 2025 Index. In the last six months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2025 without requiring additional approval by the Board of Trustees (the “Board”) of PowerShares Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval if a majority of the Board determines the change to be in the best interest of the Fund. The Board may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Adviser uses quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that resemble the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, sector, duration and other financial characteristics of fixed income instruments. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular Underlying Index components on the performance of the Underlying Index and the availability of particular securities in the secondary market. However, the Fund may use replication to seek to achieve its investment objective if practicable. A replication strategy involves generally investing in all of the securities in the Underlying Index with the same weights as the Underlying Index. There may also be instances when the Adviser may choose to overweight another security in the Underlying Index or purchase (or sell) securities not in the Underlying Index, which the Adviser believes are appropriate to substitute for one or more Underlying Index components in seeking to accurately track the Underlying Index, such as: (i) regulatory requirements possibly affecting the Fund’s ability to hold a security in the Underlying Index or (ii) liquidity concerns possibly affecting the Fund’s ability to purchase or sell a security in the Underlying Index. In addition, from time to time, securities are added to or removed from the Underlying Index. The Fund may sell securities that are represented in the Underlying Index or purchase securities that are not yet represented in the Underlying Index in anticipation of their removal from or addition to the Underlying Index pursuant to scheduled reconstitutions and rebalancings of the Underlying Index. The Fund will concentrate its investments (i.e., invest 25% or more of its assets) in securities issued by companies whose principal business activities are in the same industry or group of industries to the extent the Underlying Index is so concentrated. As of May 31, 2017, the financial and consumer staples sectors each represented a substantial portion of the Underlying Index.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

46

Asset Class  Risk . The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk . If the Underlying Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries and the Fund’s performance will be particularly susceptible to adverse events impacting such industry.

Consumer Staples Sector Risk . Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk . The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Declining Yield Risk . During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk. During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk . The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Fluctuation of Yield and Liquidation Amount Risk . The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk . The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include risks associated with differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

Income Risk . The Fund’s income may decline during a period of falling interest rates if the Fund holds floating or variable rate debt securities or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund’s shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

47

Interest Rate Risk . Investments in fixed-income instruments are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s holdings and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects on the financial markets and the Fund’s investments. Fixed-income instruments with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk . The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk . It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Adviser for purposes of the Fund’s net asset value (“NAV”), causing the Fund to be less liquid and unable to realize what the Adviser believes should be the price of the investment. Valuation of Fund investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the historically low interest rate environment as of the date of this prospectus.

Market Price Risk . Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk . The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world. The performance of these investments may underperform the general securities markets or other types of securities.

Non-Diversification Risk . The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk . Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Underlying Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Underlying Index.

Prepayment Risk . Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk . U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

48

Risk of Cash Transactions . In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Tracking Error Risk . The performance of the Fund may diverge from that of the Underlying Index for a number of reasons, including operating expenses, transaction costs, cash flows and operational inefficiencies. The Fund’s return also may diverge from the return of the Underlying Index because the Fund bears the costs and risks associated with buying and selling securities (especially when rebalancing the Fund’s securities holdings to reflect changes in the Underlying Index) while such costs and risks are not factored into the return of the Underlying Index. Transaction costs, including brokerage costs, will decrease the Fund’s NAV to the extent not offset by the transaction fee payable by an Authorized Participant. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. In addition, the Fund’s use of a representative sampling approach may cause the Fund’s returns 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. Errors in the Underlying Index data, the Underlying Index computations and/or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. In addition, the Fund may be unable to invest in certain securities included in the Underlying Index, or invest in them in the exact proportions in which they are represented in the Underlying Index, due to legal restrictions or limitations imposed by the governments of certain countries, a lack of liquidity in markets in which such securities trade, potential adverse tax consequences or other regulatory reasons. To the extent the Fund calculates its NAV based on fair value prices and the value of the Underlying Index is based on the securities’ closing prices (i.e., the value of the Underlying Index is not based on fair value prices), the Fund’s ability to track the Underlying Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities, and such sale may cause the Fund to realize a loss and, thus, the Fund’s performance to deviate from the performance of the Underlying Index. In light of the factors discussed above, the Fund’s return may deviate significantly from the return of the Underlying Index.

Performance

As of the date of this Prospectus, the Fund has not commenced operations and therefore does not have a performance history. Once available, the Fund’s performance information will be accessible on the Fund’s website at www.powershares.com and will provide some indication of the risks of investing in the Fund.

49

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only with APs and only in large blocks of 150,000 Shares (each block of Shares is called a “Creation Unit”), or multiples thereof (“Creation Unit Aggregations”), in exchange for the deposit or delivery of a basket of securities and/or cash. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares may be purchased and sold only on a national securities exchange through brokers. Shares will be listed for trading on NYSE Arca, Inc. (the “Exchange”) and because the Shares will trade at market prices rather than NAV, Shares may trade at prices greater than NAV (at a premium), at NAV, or less than NAV (at a discount).

Tax Information

The Fund’s distributions will generally be taxable, typically as either ordinary income or long-term capital gain, unless you are invested through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account; in such cases, taxation will be deferred until assets are withdrawn from the plan. A sale of Shares may result in short- or long-term capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund’s distributor or its related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary’s web-site for more information.

Summary Information

Investment Objective

The PowerShares BulletShares 2026 Corporate Bond Portfolio (the “Fund”) seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an investment grade corporate bond index called the Nasdaq BulletShares ^® USD Corporate Bond 2026 Index (the “2026 Index” or the “Underlying Index”).

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. This example does not include the brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. At the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of the 2026 Index. The 2026 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2017, approximately 251 investment grade corporate bonds with effective maturities in the year 2026. The 2026 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated investment-grade corporate bonds with effective maturities in the year 2026. The effective

51

maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security is determined in accordance with a rules-based methodology developed by Accretive Asset Management, LLC (“Accretive” or the “Index Provider”). The actual maturity of a callable security may change because an issuer of a callable security may “call” or repay the amount owed under the security before its stated maturity. As of the date of this Prospectus, the expected duration of the 2026 Index, and thus of the Fund, is 7 to 9 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Accretive is affiliated with Invesco PowerShares Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Fund has a designated year of maturity of 2026 and will terminate on or about December 31, 2026. In connection with such termination, the Fund will make a cash distribution to then-current shareholders of its net assets after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount at maturity. The Fund will invest at least 80% of its total assets in component securities that comprise the 2026 Index. In the last six months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2026 without requiring additional approval by the Board of Trustees (the “Board”) of PowerShares Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval if a majority of the Board determines the change to be in the best interest of the Fund. The Board may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Adviser uses quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that resemble the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, sector, duration and other financial characteristics of fixed income instruments. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular Underlying Index components on the performance of the Underlying Index and the availability of particular securities in the secondary market. However, the Fund may use replication to seek to achieve its investment objective if practicable. A replication strategy involves generally investing in all of the securities in the Underlying Index with the same weights as the Underlying Index. There may also be instances when the Adviser may choose to overweight another security in the Underlying Index or purchase (or sell) securities not in the Underlying Index, which the Adviser believes are appropriate to substitute for one or more Underlying Index components in seeking to accurately track the Underlying Index, such as: (i) regulatory requirements possibly affecting the Fund’s ability to hold a security in the Underlying Index or (ii) liquidity concerns possibly affecting the Fund’s ability to purchase or sell a security in the Underlying Index. In addition, from time to time, securities are added to or removed from the Underlying Index. The Fund may sell securities that are represented in the Underlying Index or purchase securities that are not yet represented in the Underlying Index in anticipation of their removal from or addition to the Underlying Index pursuant to scheduled reconstitutions and rebalancings of the Underlying Index. The Fund will concentrate its investments (i.e., invest 25% or more of its assets) in securities issued by companies whose principal business activities are in the same industry or group of industries to the extent the Underlying Index is so concentrated. As of May 31, 2017, the financial and consumer staples sectors each represented a substantial portion of the Underlying Index.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

52

Asset Class  Risk . The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk . If the Underlying Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries and the Fund’s performance will be particularly susceptible to adverse events impacting such industry.

Consumer Staples Sector Risk . Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk . The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Declining Yield Risk . During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk . During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk . The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Fluctuation of Yield and Liquidation Amount Risk . The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk . The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include risks associated with differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

Income Risk . The Fund’s income may decline during a period of falling interest rates if the Fund holds floating or variable rate debt securities or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund’s shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

53

Interest Rate Risk . Investments in fixed-income instruments are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s holdings and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects on the financial markets and the Fund’s investments. Fixed-income instruments with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk . The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk . It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Adviser for purposes of the Fund’s net asset value (“NAV”), causing the Fund to be less liquid and unable to realize what the Adviser believes should be the price of the investment. Valuation of Fund investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the historically low interest rate environment as of the date of this prospectus.

Market Price Risk . Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors.

As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk . The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world. The performance of these investments may underperform the general securities markets or other types of securities.

Prepayment Risk . Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk . U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

54

Risk of Cash Transactions . In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Tracking Error Risk . The performance of the Fund may diverge from that of the Underlying Index for a number of reasons, including operating expenses, transaction costs, cash flows and operational inefficiencies.

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only with APs and only in large blocks of 150,000 Shares (each block of Shares is called a “Creation Unit”), or multiples thereof (“Creation Unit Aggregations”), in exchange for the deposit or delivery of a basket of securities and/or cash. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares may be purchased and sold only on a national securities exchange through brokers. Shares will be listed for trading on NYSE Arca, Inc. (the “Exchange”) and because the Shares will trade at market prices rather than NAV, Shares may trade at prices greater than NAV (at a premium), at NAV, or less than NAV (at a discount).

Tax Information

The Fund’s distributions will generally be taxable, typically as either ordinary income or long-term capital gain, unless you are invested through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account; in such cases, taxation will be deferred until assets are withdrawn from the plan. A sale of Shares may result in short- or long-term capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund’s distributor or its related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary’s web-site for more information.

Summary Information

Investment Objective

The PowerShares BulletShares 2027 Corporate Bond Portfolio (the “Fund”) seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an investment grade corporate bond index called the Nasdaq BulletShares ^® USD Corporate Bond 2027 Index (the “2027 Index” or the “Underlying Index”).

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

(1)      “Other Expenses” are based on estimated amounts for the current fiscal year.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. This example does not include the brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. At the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of the 2027 Index. The 2027 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2017, approximately 133 investment grade corporate bonds with effective maturities in the year 2027. The 2027 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated investment-grade corporate bonds with effective maturities in the year 2027. The effective

57

maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security is determined in accordance with a rules-based methodology developed by Accretive Asset Management, LLC (“Accretive” or the “Index Provider”). The actual maturity of a callable security may change because an issuer of a callable security may “call” or repay the amount owed under the security before its stated maturity. As of the date of this Prospectus, the expected duration of the 2027 Index, and thus of the Fund, is 7.97 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Accretive is affiliated with Invesco PowerShares Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Fund has a designated year of maturity of 2027 and will terminate on or about December 31, 2027. In connection with such termination, the Fund will make a cash distribution to then-current shareholders of its net assets after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount at maturity. The Fund will invest at least 80% of its total assets in component securities that comprise the 2027 Index. In the last six months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2027 without requiring additional approval by the Board of Trustees (the “Board”) of PowerShares Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval if a majority of the Board determines the change to be in the best interest of the Fund. The Board may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Adviser uses quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that resemble the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, sector, duration and other financial characteristics of fixed income instruments. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular Underlying Index components on the performance of the Underlying Index and the availability of particular securities in the secondary market. However, the Fund may use replication to seek to achieve its investment objective if practicable. A replication strategy involves generally investing in all of the securities in the Underlying Index with the same weights as the Underlying Index. There may also be instances when the Adviser may choose to overweight another security in the Underlying Index or purchase (or sell) securities not in the Underlying Index, which the Adviser believes are appropriate to substitute for one or more Underlying Index components in seeking to accurately track the Underlying Index, such as: (i) regulatory requirements possibly affecting the Fund’s ability to hold a security in the Underlying Index or (ii) liquidity concerns possibly affecting the Fund’s ability to purchase or sell a security in the Underlying Index. In addition, from time to time, securities are added to or removed from the Underlying Index. The Fund may sell securities that are represented in the Underlying Index or purchase securities that are not yet represented in the Underlying Index in anticipation of their removal from or addition to the Underlying Index pursuant to scheduled reconstitutions and rebalancings of the Underlying Index. The Fund will concentrate its investments (i.e., invest 25% or more of its assets) in securities issued by companies whose principal business activities are in the same industry or group of industries to the extent the Underlying Index is so concentrated. As of August 31, 2017, the financial sector represented a substantial portion of the Underlying Index.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

58

Asset Class  Risk . The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk . If the Underlying Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of Shares may rise and fall more than the value of Shares that invests in securities of companies in a broader range of industries and the Fund’s performance will be particularly susceptible to adverse events impacting such industry.

Credit Risk . The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Declining Yield Risk . During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk . During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Financial Sector Risk . The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector.

Fluctuation of Yield and Liquidation Amount Risk . The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk . The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include risks associated with differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

Income Risk . The Fund’s income may decline during a period of falling interest rates if the Fund holds floating or variable rate debt securities or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund’s shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk . Investments in fixed-income instruments are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s holdings and share price to decline. The risks

59

associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects on the financial markets and the Fund’s investments. Fixed-income instruments with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk . The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk . It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Adviser for purposes of the Fund’s net asset value (“NAV”), causing the Fund to be less liquid and unable to realize what the Adviser believes should be the price of the investment. Valuation of Fund investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the historically low interest rate environment as of the date of this prospectus.

Market Price Risk . Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk . The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world. The performance of these investments may underperform the general securities markets or other types of securities.

Non-Diversification Risk . The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk . Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Underlying Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Underlying Index.

Prepayment Risk . Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk . U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund. These regulations and laws impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

60

Risk of Cash Transactions . In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Tracking Error Risk . The performance of the Fund may diverge from that of the Underlying Index for a number of reasons, including operating expenses, transaction costs, cash flows and operational inefficiencies. The Fund’s return also may diverge from the return of the Underlying Index because the Fund bears the costs and risks associated with buying and selling securities (especially when rebalancing the Fund’s securities holdings to reflect changes in the Underlying Index) while such costs and risks are not factored into the return of the Underlying Index. Transaction costs, including brokerage costs, will decrease the Fund’s NAV to the extent not offset by the transaction fee payable by an “Authorized Participant.” Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. In addition, the Fund’s use of a representative sampling approach may cause the Fund’s returns 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. Errors in the Underlying Index data, the Underlying Index computations and/or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. In addition, the Fund may be unable to invest in certain securities included in the Underlying Index, or invest in them in the exact proportions in which they are represented in the Underlying Index, due to legal restrictions or limitations imposed by the governments of certain countries, a lack of liquidity in markets in which such securities trade, potential adverse tax consequences or other regulatory reasons. To the extent the Fund calculates its NAV based on fair value prices and the value of the Underlying Index is based on the securities’ closing prices (i.e., the value of the Underlying Index is not based on fair value prices), the Fund’s ability to track the Underlying Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities, and such sale may cause the Fund to realize a loss and, thus, the Fund’s performance to deviate from the performance of the Underlying Index. In light of the factors discussed above, the Fund’s return may deviate significantly from the return of the Underlying Index.

Performance

As of the date of this Prospectus, the Fund has not commenced operations and therefore does not have a performance history. Once available, the Fund’s performance information will be accessible on the Fund’s website at www.powershares.com and will provide some indication of the risks of investing in the Fund.

61

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only with APs and only in large blocks of 150,000 Shares (each block of Shares is called a “Creation Unit”), or multiples thereof (“Creation Unit Aggregations”), in exchange for the deposit or delivery of a basket of securities and/or cash. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares may be purchased and sold only on a national securities exchange through brokers. Shares will be listed for trading on NYSE Arca, Inc. (the “Exchange”) and because the Shares will trade at market prices rather than NAV, Shares may trade at prices greater than NAV (at a premium), at NAV, or less than NAV (at a discount).

Tax Information

The Fund’s distributions will generally be taxable, typically as either ordinary income or long-term capital gain, unless you are invested through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account; in such cases, taxation will be deferred until assets are withdrawn from the plan. A sale of Shares may result in short- or long-term capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund’s distributor or its related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary’s web-site for more information.

Summary Information

Investment Objective

The PowerShares BulletShares 2018 High Yield Corporate Bond Portfolio (the “Fund”) seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of a high yield corporate bond index called the Nasdaq BulletShares ^® USD High Yield Corporate Bond 2018 Index (the “High Yield 2018 Index” or the “Underlying Index”).

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. This example does not include the brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. At the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of the High Yield 2018 Index. The High Yield 2018 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2017, approximately 112 high yield corporate bonds (which also may be known as “junk bonds”) with effective maturities in the year 2018. The High Yield 2018 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated high yield

63

corporate bonds with effective maturities in the year 2018. The effective maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security is determined in accordance with a rules-based methodology developed by Accretive Asset Management, LLC (“Accretive” or the “Index Provider”). The actual maturity of a callable security may change because an issuer of a callable security may “call” or repay the amount owed under the security before its stated maturity. As of the date of this Prospectus, the expected duration of the High Yield 2018 Index, and thus of the Fund, is 0.5 to 1 year. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Accretive is affiliated with Invesco PowerShares Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Fund has a designated year of maturity of 2018 and will terminate on or about December 31, 2018. In connection with such termination, the Fund will make a cash distribution to then-current shareholders of its net assets after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount at maturity. The Fund will invest at least 80% of its total assets in component securities that comprise the Underlying Index. There are no minimum credit rating requirements for securities that the Fund may purchase; however, the Fund will not purchase securities that are in default. In the last twelve months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2018 without requiring additional approval by the Board of Trustees (the “Board”) of PowerShares Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval if a majority of the Board determines the change to be in the best interest of the Fund. The Board may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Adviser uses quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that resemble the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, sector, duration and other financial characteristics of fixed income instruments. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular Underlying Index components on the performance of the Underlying Index and the availability of particular securities in the secondary market. However, the Fund may use replication to seek to achieve its investment objective if practicable. A replication strategy involves generally investing in all of the securities in the Underlying Index with the same weights as the Underlying Index. There may also be instances when the Adviser may choose to overweight another security in the Underlying Index or purchase (or sell) securities not in the Underlying Index, which the Adviser believes are appropriate to substitute for one or more Underlying Index components in seeking to accurately track the Underlying Index, such as: (i) regulatory requirements possibly affecting the Fund’s ability to hold a security in the Underlying Index or (ii) liquidity concerns possibly affecting the Fund’s ability to purchase or sell a security in the Underlying Index. In addition, from time to time, securities are added to or removed from the Underlying Index. The Fund may sell securities that are represented in the Underlying Index or purchase securities that are not yet represented in the Underlying Index in anticipation of their removal from or addition to the Underlying Index pursuant to scheduled reconstitutions and rebalancings of the Underlying Index. The Fund will concentrate its investments (i.e., invest 25% or more of its assets) in securities issued by companies whose principal business activities are in the same industry or group of industries to the extent the Underlying Index is so concentrated. As of May 31, 2017, the consumer discretionary and telecommunications sectors each represented a substantial portion of the Underlying Index.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

64

Asset Class  Risk . The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk . If the Underlying Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries and the Fund’s performance will be particularly susceptible to adverse events impacting such industry.

Consumer Discretionary Sector Risk . The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns. The Fund may be adversely affected by events or developments negatively impacting the consumer discretionary sector or issuers within the consumer discretionary sector.

Credit Risk . The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Declining Yield Risk . During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk . During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Fluctuation of Yield and Liquidation Amount Risk . The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk . The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include risks associated with differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

High Yield and Unrated Securities Risk . High yield, below investment grade and unrated high risk debt securities (which also may be known as “junk bonds”) may present additional risks because these securities may be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, present more credit risk than investment grade bonds and subject to greater risk of default. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.

Income Risk . The Fund’s income may decline during a period of falling interest rates if the Fund holds floating or variable rate debt securities or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund’s shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

65

Interest Rate Risk. Investments in fixed-income instruments are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s holdings and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects on the financial markets and the Fund’s investments. Fixed-income instruments with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk . The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk . It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Adviser for purposes of the Fund’s net asset value (“NAV”), causing the Fund to be less liquid and unable to realize what the Adviser believes should be the price of the investment. Valuation of Fund investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the historically low interest rate environment as of the date of this prospectus.

Market Price Risk . Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk . The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world. The performance of these investments may underperform the general securities markets or other types of securities.

Non-Diversification Risk . The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk . Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Underlying Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Underlying Index.

Prepayment Risk . Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk . U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

66

Restricted Securities Risk . Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.

Risk of Cash Transactions . In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Telecommunications Sector Risk . The telecommunications sector may be affected by extensive government regulation, industry competition and obsolescence of telecommunications products and services due to technological advancement. The Fund may be adversely affected by events or developments negatively impacting the telecommunications sector or issuers within the telecommunications sector.

Tracking Error Risk . The performance of the Fund may diverge from that of the Underlying Index for a number of reasons, including operating expenses, transaction costs, cash flows and operational inefficiencies. The Fund’s return also may diverge from the return of the Underlying Index because the Fund bears the costs and risks associated with buying and selling securities (especially when rebalancing the Fund’s securities holdings to reflect changes in the Underlying Index) while such costs and risks are not factored into the return of the Underlying Index. Transaction costs, including brokerage costs, will decrease the Fund’s NAV to the extent not offset by the transaction fee payable by an Authorized Participant. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. In addition, the Fund’s use of a representative sampling approach may cause the Fund’s returns 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. Errors in the Underlying Index data, the Underlying Index computations and/or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. In addition, the Fund may be unable to invest in certain securities included in the Underlying Index, or invest in them in the exact proportions in which they are represented in the Underlying Index, due to legal restrictions or limitations imposed by the governments of certain countries, a lack of liquidity in markets in which such securities trade, potential adverse tax consequences or other regulatory reasons. To the extent the Fund calculates its NAV based on fair value prices and the value of the Underlying Index is based on the securities’ closing prices (i.e., the value of the Underlying Index is not based on fair value prices), the Fund’s ability to track the Underlying Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities, and such sale may cause the Fund to realize a loss and, thus, the Fund’s performance to deviate from the performance of the Underlying Index. In light of the factors discussed above, the Fund’s return may deviate significantly from the return of the Underlying Index.

Performance

As of the date of this Prospectus, the Fund has not commenced operations and therefore does not have a performance history. Once available, the Fund’s performance information will be accessible on the Fund’s website at www.powershares.com and will provide some indication of the risks of investing in the Fund.

67

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only with APs and only in large blocks of 100,000 Shares (each block of Shares is called a “Creation Unit”), or multiples thereof (“Creation Unit Aggregations”), in exchange for the deposit or delivery of a basket of securities and/or cash. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares may be purchased and sold only on a national securities exchange through brokers. Shares will be listed for trading on NYSE Arca, Inc. (the “Exchange”) and because the Shares will trade at market prices rather than NAV, Shares may trade at prices greater than NAV (at a premium), at NAV, or less than NAV (at a discount).

Tax Information

The Fund’s distributions will generally be taxable, typically as either ordinary income or long-term capital gain, unless you are invested through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account; in such cases, taxation will be deferred until assets are withdrawn from the plan. A sale of Shares may result in short- or long-term capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund’s distributor or its related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary’s web-site for more information.

Summary Information

Investment Objective

The PowerShares BulletShares 2019 High Yield Corporate Bond Portfolio (the “Fund”) seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of a high yield corporate bond index called the Nasdaq BulletShares ^® USD High Yield Corporate Bond 2019 Index (the “High Yield 2019 Index” or the “Underlying Index”).

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. This example does not include the brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. At the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of the High Yield 2019 Index. The High Yield 2019 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2017, approximately 146 high yield corporate bonds (which also may be known as “junk bonds”) with effective maturities in the year 2019. The High Yield 2019 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated high yield

69

corporate bonds with effective maturities in the year 2019. The effective maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security is determined in accordance with a rules-based methodology developed by Accretive Asset Management, LLC (“Accretive” or the “Index Provider”). The actual maturity of a callable security may change because an issuer of a callable security may “call” or repay the amount owed under the security before its stated maturity. As of the date of this Prospectus, the expected duration of the High Yield 2019 Index, and thus of the Fund, is 1 to 2 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Accretive is affiliated with Invesco PowerShares Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Fund has a designated year of maturity of 2019 and will terminate on or about December 31, 2019. In connection with such termination, the Fund will make a cash distribution to then-current shareholders of its net assets after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount at maturity. The Fund will invest at least 80% of its total assets in component securities that comprise the Underlying Index. There are no minimum credit rating requirements for securities that the Fund may purchase; however, the Fund will not purchase securities that are in default. In the last twelve months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2019 without requiring additional approval by the Board of Trustees (the “Board”) of PowerShares Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval if a majority of the Board determines the change to be in the best interest of the Fund. The Board may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Adviser uses quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that resemble the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, sector, duration and other financial characteristics of fixed income instruments. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular Underlying Index components on the performance of the Underlying Index and the availability of particular securities in the secondary market. However, the Fund may use replication to seek to achieve its investment objective if practicable. A replication strategy involves generally investing in all of the securities in the Underlying Index with the same weights as the Underlying Index. There may also be instances when the Adviser may choose to overweight another security in the Underlying Index or purchase (or sell) securities not in the Underlying Index, which the Adviser believes are appropriate to substitute for one or more Underlying Index components in seeking to accurately track the Underlying Index, such as: (i) regulatory requirements possibly affecting the Fund’s ability to hold a security in the Underlying Index or (ii) liquidity concerns possibly affecting the Fund’s ability to purchase or sell a security in the Underlying Index. In addition, from time to time, securities are added to or removed from the Underlying Index. The Fund may sell securities that are represented in the Underlying Index or purchase securities that are not yet represented in the Underlying Index in anticipation of their removal from or addition to the Underlying Index pursuant to scheduled reconstitutions and rebalancings of the Underlying Index. The Fund will concentrate its investments (i.e., invest 25% or more of its assets) in securities issued by companies whose principal business activities are in the same industry or group of industries to the extent the Underlying Index is so concentrated. As of May 31, 2017, the telecommunications sector represented a substantial portion of the Underlying Index.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

70

Asset Class  Risk . The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk . If the Underlying Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries and the Fund’s performance will be particularly susceptible to adverse events impacting such industry.

Credit Risk . The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Declining Yield Risk . During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk . During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Fluctuation of Yield and Liquidation Amount Risk . The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk . The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include risks associated with differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

High Yield and Unrated Securities Risk . High yield, below investment grade and unrated high risk debt securities (which also may be known as “junk bonds”) may present additional risks because these securities may be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, present more credit risk than investment grade bonds and subject to greater risk of default. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.

Income Risk . The Fund’s income may decline during a period of falling interest rates if the Fund holds floating or variable rate debt securities or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund’s shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk . Investments in fixed-income instruments are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s holdings and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects on the financial markets and the Fund’s investments. Fixed-income instruments with longer durations are subject to more volatility than those with shorter durations.

71

Issuer-Specific Changes Risk . The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk . It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Adviser for purposes of the Fund’s net asset value (“NAV”), causing the Fund to be less liquid and unable to realize what the Adviser believes should be the price of the investment. Valuation of Fund investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the historically low interest rate environment as of the date of this prospectus.

Market Price Risk . Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk. The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world. The performance of these investments may underperform the general securities markets or other types of securities.

Non-Diversification Risk . The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk . Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Underlying Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Underlying Index.

Prepayment Risk . Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk . U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

Restricted Securities Risk . Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.

Risk of Cash Transactions . In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Telecommunications Sector Risk . The telecommunications sector may be affected by extensive government regulation, industry competition and obsolescence of telecommunications products and

72

services due to technological advancement. The Fund may be adversely affected by events or developments negatively impacting the telecommunications sector or issuers within the telecommunications sector.

Tracking Error Risk . The performance of the Fund may diverge from that of the Underlying Index for a number of reasons, including operating expenses, transaction costs, cash flows and operational inefficiencies. The Fund’s return also may diverge from the return of the Underlying Index because the Fund bears the costs and risks associated with buying and selling securities (especially when rebalancing the Fund’s securities holdings to reflect changes in the Underlying Index) while such costs and risks are not factored into the return of the Underlying Index. Transaction costs, including brokerage costs, will decrease the Fund’s NAV to the extent not offset by the transaction fee payable by an Authorized Participant. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. In addition, the Fund’s use of a representative sampling approach may cause the Fund’s returns 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. Errors in the Underlying Index data, the Underlying Index computations and/or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. In addition, the Fund may be unable to invest in certain securities included in the Underlying Index, or invest in them in the exact proportions in which they are represented in the Underlying Index, due to legal restrictions or limitations imposed by the governments of certain countries, a lack of liquidity in markets in which such securities trade, potential adverse tax consequences or other regulatory reasons. To the extent the Fund calculates its NAV based on fair value prices and the value of the Underlying Index is based on the securities’ closing prices (i.e., the value of the Underlying Index is not based on fair value prices), the Fund’s ability to track the Underlying Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities, and such sale may cause the Fund to realize a loss and, thus, the Fund’s performance to deviate from the performance of the Underlying Index. In light of the factors discussed above, the Fund’s return may deviate significantly from the return of the Underlying Index.

Performance

As of the date of this Prospectus, the Fund has not commenced operations and therefore does not have a performance history. Once available, the Fund’s performance information will be accessible on the Fund’s website at www.powershares.com and will provide some indication of the risks of investing in the Fund.

73

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only with APs and only in large blocks of 100,000 Shares (each block of Shares is called a “Creation Unit”), or multiples thereof (“Creation Unit Aggregations”), in exchange for the deposit or delivery of a basket of securities and/or cash. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares may be purchased and sold only on a national securities exchange through brokers. Shares will be listed for trading on NYSE Arca, Inc. (the “Exchange”) and because the Shares will trade at market prices rather than NAV, Shares may trade at prices greater than NAV (at a premium), at NAV, or less than NAV (at a discount).

Tax Information

The Fund’s distributions will generally be taxable, typically as either ordinary income or long-term capital gain, unless you are invested through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account; in such cases, taxation will be deferred until assets are withdrawn from the plan. A sale of Shares may result in short- or long-term capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund’s distributor or its related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary’s web-site for more information.

Summary Information

Investment Objective

The PowerShares BulletShares 2020 High Yield Corporate Bond Portfolio (the “Fund”) seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of a high yield corporate bond index called the Nasdaq BulletShares ^® USD High Yield Corporate Bond 2020 Index (the “High Yield 2020 Index” or the “Underlying Index”).

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. This example does not include the brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. At the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of the High Yield 2020 Index. The High Yield 2020 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2017, approximately 204 high yield corporate bonds (which also may be known as “junk bonds”) with effective maturities in the year 2020. The High Yield 2020 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated high yield

75

corporate bonds with effective maturities in the year 2020. The effective maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security is determined in accordance with a rules-based methodology developed by Accretive Asset Management, LLC (“Accretive” or the “Index Provider”). The actual maturity of a callable security may change because an issuer of a callable security may “call” or repay the amount owed under the security before its stated maturity. As of the date of this Prospectus, the expected duration of the High Yield 2020 Index, and thus of the Fund, is 1 to 3 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Accretive is affiliated with Invesco PowerShares Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Fund has a designated year of maturity of 2020 and will terminate on or about December 31, 2020. In connection with such termination, the Fund will make a cash distribution to then-current shareholders of its net assets after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount at maturity. The Fund will invest at least 80% of its total assets in component securities that comprise the Underlying Index. There are no minimum credit rating requirements for securities that the Fund may purchase; however, the Fund will not purchase securities that are in default. In the last twelve months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2020 without requiring additional approval by the Board of Trustees (the “Board”) of PowerShares Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval if a majority of the Board determines the change to be in the best interest of the Fund. The Board may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Adviser uses quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that resemble the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, sector, duration and other financial characteristics of fixed income instruments. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular Underlying Index components on the performance of the Underlying Index and the availability of particular securities in the secondary market. However, the Fund may use replication to seek to achieve its investment objective if practicable. A replication strategy involves generally investing in all of the securities in the Underlying Index with the same weights as the Underlying Index. There may also be instances when the Adviser may choose to overweight another security in the Underlying Index or purchase (or sell) securities not in the Underlying Index, which the Adviser believes are appropriate to substitute for one or more Underlying Index components in seeking to accurately track the Underlying Index, such as: (i) regulatory requirements possibly affecting the Fund’s ability to hold a security in the Underlying Index or (ii) liquidity concerns possibly affecting the Fund’s ability to purchase or sell a security in the Underlying Index. In addition, from time to time, securities are added to or removed from the Underlying Index. The Fund may sell securities that are represented in the Underlying Index or purchase securities that are not yet represented in the Underlying Index in anticipation of their removal from or addition to the Underlying Index pursuant to scheduled reconstitutions and rebalancings of the Underlying Index. The Fund will concentrate its investments (i.e., invest 25% or more of its assets) in securities issued by companies whose principal business activities are in the same industry or group of industries to the extent the Underlying Index is so concentrated. As of May 31, 2017, the telecommunications and consumer staples sectors each represented a substantial portion of the Underlying Index.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

76

Asset Class  Risk . The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk . If the Underlying Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries and the Fund’s performance will be particularly susceptible to adverse events impacting such industry.

Consumer Staples Sector Risk . Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk . The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Declining Yield Risk . During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Extension Risk . During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Fluctuation of Yield and Liquidation Amount Risk . The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk . The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include risks associated with differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

High Yield and Unrated Securities Risk . High yield, below investment grade and unrated high risk debt securities (which also may be known as “junk bonds”) may present additional risks because these securities may be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, present more credit risk than investment grade bonds and subject to greater risk of default. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.

Income Risk . The Fund’s income may decline during a period of falling interest rates if the Fund holds floating or variable rate debt securities or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund’s shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

77

Interest Rate Risk . Investments in fixed-income instruments are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s holdings and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects on the financial markets and the Fund’s investments. Fixed-income instruments with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk . The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk . It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Adviser for purposes of the Fund’s net asset value (“NAV”), causing the Fund to be less liquid and unable to realize what the Adviser believes should be the price of the investment. Valuation of Fund investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the historically low interest rate environment as of the date of this prospectus.

Market Price Risk. Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk . The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world. The performance of these investments may underperform the general securities markets or other types of securities.

Non-Diversification Risk . The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk . Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Underlying Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Underlying Index.

Prepayment Risk . Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk . U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

78

Restricted Securities Risk . Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.

Risk of Cash Transactions . In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Telecommunications Sector Risk . The telecommunications sector may be affected by extensive government regulation, industry competition and obsolescence of telecommunications products and services due to technological advancement. The Fund may be adversely affected by events or developments negatively impacting the telecommunications sector or issuers within the telecommunications sector.

Tracking Error Risk . The performance of the Fund may diverge from that of the Underlying Index for a number of reasons, including operating expenses, transaction costs, cash flows and operational inefficiencies. The Fund’s return also may diverge from the return of the Underlying Index because the Fund bears the costs and risks associated with buying and selling securities (especially when rebalancing the Fund’s securities holdings to reflect changes in the Underlying Index) while such costs and risks are not factored into the return of the Underlying Index. Transaction costs, including brokerage costs, will decrease the Fund’s NAV to the extent not offset by the transaction fee payable by an Authorized Participant. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. In addition, the Fund’s use of a representative sampling approach may cause the Fund’s returns 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. Errors in the Underlying Index data, the Underlying Index computations and/or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. In addition, the Fund may be unable to invest in certain securities included in the Underlying Index, or invest in them in the exact proportions in which they are represented in the Underlying Index, due to legal restrictions or limitations imposed by the governments of certain countries, a lack of liquidity in markets in which such securities trade, potential adverse tax consequences or other regulatory reasons. To the extent the Fund calculates its NAV based on fair value prices and the value of the Underlying Index is based on the securities’ closing prices (i.e., the value of the Underlying Index is not based on fair value prices), the Fund’s ability to track the Underlying Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities, and such sale may cause the Fund to realize a loss and, thus, the Fund’s performance to deviate from the performance of the Underlying Index. In light of the factors discussed above, the Fund’s return may deviate significantly from the return of the Underlying Index.

Performance

As of the date of this Prospectus, the Fund has not commenced operations and therefore does not have a performance history. Once available, the Fund’s performance information will be accessible on the Fund’s website at www.powershares.com and will provide some indication of the risks of investing in the Fund.

79

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only with APs and only in large blocks of 100,000 Shares (each block of Shares is called a “Creation Unit”), or multiples thereof (“Creation Unit Aggregations”), in exchange for the deposit or delivery of a basket of securities and/or cash. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares may be purchased and sold only on a national securities exchange through brokers. Shares will be listed for trading on NYSE Arca, Inc. (the “Exchange”) and because the Shares will trade at market prices rather than NAV, Shares may trade at prices greater than NAV (at a premium), at NAV, or less than NAV (at a discount).

Tax Information

The Fund’s distributions will generally be taxable, typically as either ordinary income or long-term capital gain, unless you are invested through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account; in such cases, taxation will be deferred until assets are withdrawn from the plan. A sale of Shares may result in short- or long-term capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund’s distributor or its related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary’s web-site for more information.

Summary Information

Investment Objective

The PowerShares BulletShares 2021 High Yield Corporate Bond Portfolio (the “Fund”) seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of a high yield corporate bond index called the Nasdaq BulletShares ^® USD High Yield Corporate Bond 2021 Index (the “High Yield 2021 Index” or the “Underlying Index”).

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. This example does not include the brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. At the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of the High Yield 2021 Index. The High Yield 2021 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2017, approximately 222 high yield corporate bonds (which also may be known as “junk bonds”) with effective maturities in the year 2021. The High Yield 2021 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated high yield

81

corporate bonds with effective maturities in the year 2021. The effective maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security is determined in accordance with a rules-based methodology developed by Accretive Asset Management, LLC (“Accretive” or the “Index Provider”). The actual maturity of a callable security may change because an issuer of a callable security may “call” or repay the amount owed under the security before its stated maturity. As of the date of this Prospectus, the expected duration of the High Yield 2021 Index, and thus of the Fund, is 1 to 4 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Accretive is affiliated with Invesco PowerShares Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Fund has a designated year of maturity of 2021 and will terminate on or about December 31, 2021. In connection with such termination, the Fund will make a cash distribution to then-current shareholders of its net assets after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount at maturity. The Fund will invest at least 80% of its total assets in component securities that comprise the Underlying Index. There are no minimum credit rating requirements for securities that the Fund may purchase; however, the Fund will not purchase securities that are in default. In the last twelve months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2021 without requiring additional approval by the Board of Trustees (the “Board”) of PowerShares Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval if a majority of the Board determines the change to be in the best interest of the Fund. The Board may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Adviser uses quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that resemble the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, sector, duration and other financial characteristics of fixed income instruments. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular Underlying Index components on the performance of the Underlying Index and the availability of particular securities in the secondary market. However, the Fund may use replication to seek to achieve its investment objective if practicable. A replication strategy involves generally investing in all of the securities in the Underlying Index with the same weights as the Underlying Index. There may also be instances when the Adviser may choose to overweight another security in the Underlying Index or purchase (or sell) securities not in the Underlying Index, which the Adviser believes are appropriate to substitute for one or more Underlying Index components in seeking to accurately track the Underlying Index, such as: (i) regulatory requirements possibly affecting the Fund’s ability to hold a security in the Underlying Index or (ii) liquidity concerns possibly affecting the Fund’s ability to purchase or sell a security in the Underlying Index. In addition, from time to time, securities are added to or removed from the Underlying Index. The Fund may sell securities that are represented in the Underlying Index or purchase securities that are not yet represented in the Underlying Index in anticipation of their removal from or addition to the Underlying Index pursuant to scheduled reconstitutions and rebalancings of the Underlying Index. The Fund will concentrate its investments (i.e., invest 25% or more of its assets) in securities issued by companies whose principal business activities are in the same industry or group of industries to the extent the Underlying Index is so concentrated. As of May 31, 2017, the telecommunications, consumer staples, consumer discretionary and energy sectors each represented a substantial portion of the Underlying Index.

82

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

Asset Class  Risk . The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk . If the Underlying Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries and the Fund’s performance will be particularly susceptible to adverse events impacting such industry.

Consumer Discretionary Sector Risk . The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income, consumer preferences, social trends and marketing campaigns. The Fund may be adversely affected by events or developments negatively impacting the consumer discretionary sector or issuers within the consumer discretionary sector.

Consumer Staples Sector Risk . Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk . The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Declining Yield Risk . During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Energy Sector Risk . The energy sector is often cyclical and highly dependent on commodities prices. Securities prices for companies in the energy sector may be affected by a variety of factors, including, among others, worldwide energy prices, exploration costs, energy conservation efforts, changes in currency exchange rates, government regulation and market, economic and political risks of the countries where energy companies are located or do business. The Fund may be adversely affected by negative developments relating to the energy sector and commodities issuers.

Extension Risk . During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Fluctuation of Yield and Liquidation Amount Risk . The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk . The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include risks associated with differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

83

High Yield and Unrated Securities Risk . High yield, below investment grade and unrated high risk debt securities (which also may be known as “junk bonds”) may present additional risks because these securities may be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, present more credit risk than investment grade bonds and subject to greater risk of default. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.

Income Risk . The Fund’s income may decline during a period of falling interest rates if the Fund holds floating or variable rate debt securities or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund’s shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk . Investments in fixed-income instruments are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s holdings and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects on the financial markets and the Fund’s investments. Fixed-income instruments with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk . The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk . It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Adviser for purposes of the Fund’s net asset value (“NAV”), causing the Fund to be less liquid and unable to realize what the Adviser believes should be the price of the investment. Valuation of Fund investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the historically low interest rate environment as of the date of this prospectus.

Market Price Risk . Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk . The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world. The performance of these investments may underperform the general securities markets or other types of securities.

Non-Diversification Risk . The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk . Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or

84

defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Underlying Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Underlying Index.

Prepayment Risk . Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

Regulatory and Legal Risk . U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

Restricted Securities Risk . Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.

Risk of Cash Transactions . In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Telecommunications Sector Risk . The telecommunications sector may be affected by extensive government regulation, industry competition and obsolescence of telecommunications products and services due to technological advancement. The Fund may be adversely affected by events or developments negatively impacting the telecommunications sector or issuers within the telecommunications sector.

Tracking Error Risk . The performance of the Fund may diverge from that of the Underlying Index for a number of reasons, including operating expenses, transaction costs, cash flows and operational inefficiencies. The Fund’s return also may diverge from the return of the Underlying Index because the Fund bears the costs and risks associated with buying and selling securities (especially when rebalancing the Fund’s securities holdings to reflect changes in the Underlying Index) while such costs and risks are not factored into the return of the Underlying Index. Transaction costs, including brokerage costs, will decrease the Fund’s NAV to the extent not offset by the transaction fee payable by an Authorized Participant. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. In addition, the Fund’s use of a representative sampling approach may cause the Fund’s returns 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. Errors in the Underlying Index data, the Underlying Index computations and/or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. In addition, the Fund may be unable to invest in certain securities included in the Underlying Index, or invest in them in the exact proportions in which they are represented in the Underlying Index, due to legal restrictions or limitations imposed by the governments of certain countries, a lack of liquidity in markets in which such securities trade, potential adverse tax consequences or other regulatory reasons. To the extent the Fund calculates its NAV based on fair value prices and the value of the Underlying Index is based on the securities’ closing prices (i.e., the value of the Underlying Index is not based on fair value prices), the Fund’s ability to track the Underlying Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities, and such sale may cause the Fund to realize a loss and, thus, the Fund’s performance to deviate from the performance of the Underlying Index. In light of the factors discussed above, the Fund’s return may deviate significantly from the return of the Underlying Index.

Performance

As of the date of this Prospectus, the Fund has not commenced operations and therefore does not have a performance history. Once available, the Fund’s performance information will be accessible on the Fund’s website at www.powershares.com and will provide some indication of the risks of investing in the Fund.

85

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only with APs and only in large blocks of 100,000 Shares (each block of Shares is called a “Creation Unit”), or multiples thereof (“Creation Unit Aggregations”), in exchange for the deposit or delivery of a basket of securities and/or cash. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares may be purchased and sold only on a national securities exchange through brokers. Shares will be listed for trading on NYSE Arca, Inc. (the “Exchange”) and because the Shares will trade at market prices rather than NAV, Shares may trade at prices greater than NAV (at a premium), at NAV, or less than NAV (at a discount).

Tax Information

The Fund’s distributions will generally be taxable, typically as either ordinary income or long-term capital gain, unless you are invested through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account; in such cases, taxation will be deferred until assets are withdrawn from the plan. A sale of Shares may result in short- or long-term capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund’s distributor or its related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary’s web-site for more information.

Summary Information

Investment Objective

The PowerShares BulletShares 2022 High Yield Corporate Bond Portfolio (the “Fund”) seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of a high yield corporate bond index called the Nasdaq BulletShares ^® USD High Yield Corporate Bond 2022 Index (the “High Yield 2022 Index” or the “Underlying Index”).

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. This example does not include the brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. At the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of the High Yield 2022 Index. The High Yield 2022 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2017, approximately 279 high yield corporate bonds (which also may be known as “junk bonds”) with effective maturities in the year 2022. The High Yield 2022 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated high yield

87

corporate bonds with effective maturities in the year 2022. The effective maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security is determined in accordance with a rules-based methodology developed by Accretive Asset Management, LLC (“Accretive” or the “Index Provider”). The actual maturity of a callable security may change because an issuer of a callable security may “call” or repay the amount owed under the security before its stated maturity. As of the date of this Prospectus, the expected duration of the High Yield 2022 Index, and thus of the Fund, is 2 to 5 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Accretive is affiliated with Invesco PowerShares Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Fund has a designated year of maturity of 2022 and will terminate on or about December 31, 2022. In connection with such termination, the Fund will make a cash distribution to then-current shareholders of its net assets after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount at maturity. The Fund will invest at least 80% of its total assets in component securities that comprise the Underlying Index. There are no minimum credit rating requirements for securities that the Fund may purchase; however, the Fund will not purchase securities that are in default. In the last twelve months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2022 without requiring additional approval by the Board of Trustees (the “Board”) of PowerShares Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval if a majority of the Board determines the change to be in the best interest of the Fund. The Board may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Adviser uses quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that resemble the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, sector, duration and other financial characteristics of fixed income instruments. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular Underlying Index components on the performance of the Underlying Index and the availability of particular securities in the secondary market. However, the Fund may use replication to seek to achieve its investment objective if practicable. A replication strategy involves generally investing in all of the securities in the Underlying Index with the same weights as the Underlying Index. There may also be instances when the Adviser may choose to overweight another security in the Underlying Index or purchase (or sell) securities not in the Underlying Index, which the Adviser believes are appropriate to substitute for one or more Underlying Index components in seeking to accurately track the Underlying Index, such as: (i) regulatory requirements possibly affecting the Fund’s ability to hold a security in the Underlying Index or (ii) liquidity concerns possibly affecting the Fund’s ability to purchase or sell a security in the Underlying Index. In addition, from time to time, securities are added to or removed from the Underlying Index. The Fund may sell securities that are represented in the Underlying Index or purchase securities that are not yet represented in the Underlying Index in anticipation of their removal from or addition to the Underlying Index pursuant to scheduled reconstitutions and rebalancings of the Underlying Index. The Fund will concentrate its investments (i.e., invest 25% or more of its assets) in securities issued by companies whose principal business activities are in the same industry or group of industries to the extent the Underlying Index is so concentrated. As of May 31, 2017, the telecommunications, consumer staples and energy sectors each represented a substantial portion of the Underlying Index.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

88

Asset Class  Risk . The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk . If the Underlying Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries and the Fund’s performance will be particularly susceptible to adverse events impacting such industry.

Consumer Staples Sector Risk . Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk . The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Declining Yield Risk . During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Energy Sector Risk . The energy sector is often cyclical and highly dependent on commodities prices. Securities prices for companies in the energy sector may be affected by a variety of factors, including, among others, worldwide energy prices, exploration costs, energy conservation efforts, changes in currency exchange rates, government regulation and market, economic and political risks of the countries where energy companies are located or do business. The Fund may be adversely affected by negative developments relating to the energy sector and commodities issuers.

Extension Risk . During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Fluctuation of Yield and Liquidation Amount Risk . The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk . The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include risks associated with differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

High Yield and Unrated Securities Risk . High yield, below investment grade and unrated high risk debt securities (which also may be known as “junk bonds”) may present additional risks because these securities may be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, present more credit risk than investment grade bonds and subject to greater risk of default. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.

89

Income Risk . The Fund’s income may decline during a period of falling interest rates if the Fund holds floating or variable rate debt securities or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund’s shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk . Investments in fixed-income instruments are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s holdings and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects on the financial markets and the Fund’s investments. Fixed-income instruments with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk . The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk . It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Adviser for purposes of the Fund’s net asset value (“NAV”), causing the Fund to be less liquid and unable to realize what the Adviser believes should be the price of the investment. Valuation of Fund investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the historically low interest rate environment as of the date of this prospectus.

Market Price Risk . Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk . The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world. The performance of these investments may underperform the general securities markets or other types of securities.

Non-Diversification Risk . The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk . Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Underlying Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Underlying Index.

Prepayment Risk . Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

90

Regulatory and Legal Risk . U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

Restricted Securities Risk . Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.

Risk of Cash Transactions . In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Telecommunications Sector Risk . The telecommunications sector may be affected by extensive government regulation, industry competition and obsolescence of telecommunications products and services due to technological advancement. The Fund may be adversely affected by events or developments negatively impacting the telecommunications sector or issuers within the telecommunications sector.

Tracking Error Risk . The performance of the Fund may diverge from that of the Underlying Index for a number of reasons, including operating expenses, transaction costs, cash flows and operational inefficiencies. The Fund’s return also may diverge from the return of the Underlying Index because the Fund bears the costs and risks associated with buying and selling securities (especially when rebalancing the Fund’s securities holdings to reflect changes in the Underlying Index) while such costs and risks are not factored into the return of the Underlying Index. Transaction costs, including brokerage costs, will decrease the Fund’s NAV to the extent not offset by the transaction fee payable by an Authorized Participant. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. In addition, the Fund’s use of a representative sampling approach may cause the Fund’s returns 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. Errors in the Underlying Index data, the Underlying Index computations and/or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. In addition, the Fund may be unable to invest in certain securities included in the Underlying Index, or invest in them in the exact proportions in which they are represented in the Underlying Index, due to legal restrictions or limitations imposed by the governments of certain countries, a lack of liquidity in markets in which such securities trade, potential adverse tax consequences or other regulatory reasons. To the extent the Fund calculates its NAV based on fair value prices and the value of the Underlying Index is based on the securities’ closing prices (i.e., the value of the Underlying Index is not based on fair value prices), the Fund’s ability to track the Underlying Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities, and such sale may cause the Fund to realize a loss and, thus, the Fund’s performance to deviate from the performance of the Underlying Index. In light of the factors discussed above, the Fund’s return may deviate significantly from the return of the Underlying Index.

Performance

As of the date of this Prospectus, the Fund has not commenced operations and therefore does not have a performance history. Once available, the Fund’s performance information will be accessible on the Fund’s website at www.powershares.com and will provide some indication of the risks of investing in the Fund.

Management of the Fund

Investment Adviser.  Invesco PowerShares Capital Management LLC (the “Adviser”).

91

Portfolio Managers.  The following individuals are responsible jointly and primarily for the day-to-day management of the Fund’s portfolio:

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only with APs and only in large blocks of 100,000 Shares (each block of Shares is called a “Creation Unit”), or multiples thereof (“Creation Unit Aggregations”), in exchange for the deposit or delivery of a basket of securities and/or cash. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares may be purchased and sold only on a national securities exchange through brokers. Shares will be listed for trading on NYSE Arca, Inc. (the “Exchange”) and because the Shares will trade at market prices rather than NAV, Shares may trade at prices greater than NAV (at a premium), at NAV, or less than NAV (at a discount).

Tax Information

The Fund’s distributions will generally be taxable, typically as either ordinary income or long-term capital gain, unless you are invested through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account; in such cases, taxation will be deferred until assets are withdrawn from the plan. A sale of Shares may result in short- or long-term capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund’s distributor or its related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary’s web-site for more information.

Summary Information

Investment Objective

The PowerShares BulletShares 2023 High Yield Corporate Bond Portfolio (the “Fund”) seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of a high yield corporate bond index called the Nasdaq BulletShares ^® USD High Yield Corporate Bond 2023 Index (the “High Yield 2023 Index” or the “Underlying Index”).

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. This example does not include the brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. At the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of the High Yield 2023 Index. The High Yield 2023 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2017, approximately 229 high yield corporate bonds (which also may be known as “junk bonds”) with effective maturities in the year 2023. The High Yield 2023 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated high yield

93

corporate bonds with effective maturities in the year 2023. The effective maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security is determined in accordance with a rules-based methodology developed by Accretive Asset Management, LLC (“Accretive” or the “Index Provider”). The actual maturity of a callable security may change because an issuer of a callable security may “call” or repay the amount owed under the security before its stated maturity. As of the date of this Prospectus, the expected duration of the High Yield 2023 Index, and thus of the Fund, is 3 to 6 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Accretive is affiliated with Invesco PowerShares Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Fund has a designated year of maturity of 2023 and will terminate on or about December 31, 2023. In connection with such termination, the Fund will make a cash distribution to then-current shareholders of its net assets after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount at maturity. The Fund will invest at least 80% of its total assets in component securities that comprise the Underlying Index. There are no minimum credit rating requirements for securities that the Fund may purchase; however, the Fund will not purchase securities that are in default. In the last twelve months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2023 without requiring additional approval by the Board of Trustees (the “Board”) of PowerShares Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval if a majority of the Board determines the change to be in the best interest of the Fund. The Board may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Adviser uses quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that resemble the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, sector, duration and other financial characteristics of fixed income instruments. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular Underlying Index components on the performance of the Underlying Index and the availability of particular securities in the secondary market. However, the Fund may use replication to seek to achieve its investment objective if practicable. A replication strategy involves generally investing in all of the securities in the Underlying Index with the same weights as the Underlying Index. There may also be instances when the Adviser may choose to overweight another security in the Underlying Index or purchase (or sell) securities not in the Underlying Index, which the Adviser believes are appropriate to substitute for one or more Underlying Index components in seeking to accurately track the Underlying Index, such as: (i) regulatory requirements possibly affecting the Fund’s ability to hold a security in the Underlying Index or (ii) liquidity concerns possibly affecting the Fund’s ability to purchase or sell a security in the Underlying Index. In addition, from time to time, securities are added to or removed from the Underlying Index. The Fund may sell securities that are represented in the Underlying Index or purchase securities that are not yet represented in the Underlying Index in anticipation of their removal from or addition to the Underlying Index pursuant to scheduled reconstitutions and rebalancings of the Underlying Index. The Fund will concentrate its investments (i.e., invest 25% or more of its assets) in securities issued by companies whose principal business activities are in the same industry or group of industries to the extent the Underlying Index is so concentrated. As of May 31, 2017, the energy, telecommunications and consumer staples sectors each represented a substantial portion of the Underlying Index.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

94

Asset Class  Risk . The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk . If the Underlying Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries and the Fund’s performance will be particularly susceptible to adverse events impacting such industry.

Consumer Staples Sector Risk . Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk . The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Declining Yield Risk . During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Energy Sector Risk . The energy sector is often cyclical and highly dependent on commodities prices. Securities prices for companies in the energy sector may be affected by a variety of factors, including, among others, worldwide energy prices, exploration costs, energy conservation efforts, changes in currency exchange rates, government regulation and market, economic and political risks of the countries where energy companies are located or do business. The Fund may be adversely affected by negative developments relating to the energy sector and commodities issuers.

Extension Risk . During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Fluctuation of Yield and Liquidation Amount Risk . The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk . The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include risks associated with differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

High Yield and Unrated Securities Risk . High yield, below investment grade and unrated high risk debt securities (which also may be known as “junk bonds”) may present additional risks because these securities may be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, present more credit risk than investment grade bonds and subject to greater risk of default. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.

95

Income Risk . The Fund’s income may decline during a period of falling interest rates if the Fund holds floating or variable rate debt securities or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund’s shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk . Investments in fixed-income instruments are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s holdings and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects on the financial markets and the Fund’s investments. Fixed-income instruments with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk . The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk . It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Adviser for purposes of the Fund’s net asset value (“NAV”), causing the Fund to be less liquid and unable to realize what the Adviser believes should be the price of the investment. Valuation of Fund investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the historically low interest rate environment as of the date of this prospectus.

Market Price Risk . Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk . The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world. The performance of these investments may underperform the general securities markets or other types of securities.

Non-Diversification Risk . The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk . Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Underlying Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Underlying Index.

Prepayment Risk . Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

96

Regulatory and Legal Risk . U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

Restricted Securities Risk . Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.

Risk of Cash Transactions . In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Telecommunications Sector Risk . The telecommunications sector may be affected by extensive government regulation, industry competition and obsolescence of telecommunications products and services due to technological advancement. The Fund may be adversely affected by events or developments negatively impacting the telecommunications sector or issuers within the telecommunications sector.

Tracking Error Risk . The performance of the Fund may diverge from that of the Underlying Index for a number of reasons, including operating expenses, transaction costs, cash flows and operational inefficiencies. The Fund’s return also may diverge from the return of the Underlying Index because the Fund bears the costs and risks associated with buying and selling securities (especially when rebalancing the Fund’s securities holdings to reflect changes in the Underlying Index) while such costs and risks are not factored into the return of the Underlying Index. Transaction costs, including brokerage costs, will decrease the Fund’s NAV to the extent not offset by the transaction fee payable by an Authorized Participant. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. In addition, the Fund’s use of a representative sampling approach may cause the Fund’s returns 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. Errors in the Underlying Index data, the Underlying Index computations and/or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. In addition, the Fund may be unable to invest in certain securities included in the Underlying Index, or invest in them in the exact proportions in which they are represented in the Underlying Index, due to legal restrictions or limitations imposed by the governments of certain countries, a lack of liquidity in markets in which such securities trade, potential adverse tax consequences or other regulatory reasons. To the extent the Fund calculates its NAV based on fair value prices and the value of the Underlying Index is based on the securities’ closing prices (i.e., the value of the Underlying Index is not based on fair value prices), the Fund’s ability to track the Underlying Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities, and such sale may cause the Fund to realize a loss and, thus, the Fund’s performance to deviate from the performance of the Underlying Index. In light of the factors discussed above, the Fund’s return may deviate significantly from the return of the Underlying Index.

Performance

As of the date of this Prospectus, the Fund has not commenced operations and therefore does not have a performance history. Once available, the Fund’s performance information will be accessible on the Fund’s website at www.powershares.com and will provide some indication of the risks of investing in the Fund.

Management of the Fund

Investment Adviser.  Invesco PowerShares Capital Management LLC (the “Adviser”).

97

Portfolio Managers.  The following individuals are responsible jointly and primarily for the day-to-day management of the Fund’s portfolio:

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only with APs and only in large blocks of 100,000 Shares (each block of Shares is called a “Creation Unit”), or multiples thereof (“Creation Unit Aggregations”), in exchange for the deposit or delivery of a basket of securities and/or cash. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares may be purchased and sold only on a national securities exchange through brokers. Shares will be listed for trading on NYSE Arca, Inc. (the “Exchange”) and because the Shares will trade at market prices rather than NAV, Shares may trade at prices greater than NAV (at a premium), at NAV, or less than NAV (at a discount).

Tax Information

The Fund’s distributions will generally be taxable, typically as either ordinary income or long-term capital gain, unless you are invested through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account; in such cases, taxation will be deferred until assets are withdrawn from the plan. A sale of Shares may result in short- or long-term capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund’s distributor or its related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary’s web-site for more information.

Summary Information

Investment Objective

The PowerShares BulletShares 2024 High Yield Corporate Bond Portfolio (the “Fund”) seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of a high yield corporate bond index called the Nasdaq BulletShares ^® USD High Yield Corporate Bond 2024 Index (the “High Yield 2024 Index” or the “Underlying Index”).

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. This example does not include the brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. At the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks investment results that correspond generally to the performance , before the Fund’s fees and expenses, of the High Yield 2024 Index. The High Yield 2024 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2017, approximately 187 high yield corporate bonds (which also may be known as “junk bonds”) with effective maturities in the year 2024. The High Yield 2024 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated high yield

99

corporate bonds with effective maturities in the year 2024. The effective maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security is determined in accordance with a rules-based methodology developed by Accretive Asset Management, LLC (“Accretive” or the “Index Provider”). The actual maturity of a callable security may change because an issuer of a callable security may “call” or repay the amount owed under the security before its stated maturity. As of the date of this Prospectus, the expected duration of the High Yield 2024 Index, and thus of the Fund, is 4 to 7 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Accretive is affiliated with Invesco PowerShares Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Fund has a designated year of maturity of 2024 and will terminate on or about December 31, 2024. In connection with such termination, the Fund will make a cash distribution to then-current shareholders of its net assets after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount at maturity. The Fund will invest at least 80% of its total assets in component securities that comprise the Underlying Index. There are no minimum credit rating requirements for securities that the Fund may purchase; however, the Fund will not purchase securities that are in default. In the last twelve months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2024 without requiring additional approval by the Board of Trustees (the “Board”) of PowerShares Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval if a majority of the Board determines the change to be in the best interest of the Fund. The Board may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Adviser uses quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that resemble the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, sector, duration and other financial characteristics of fixed income instruments. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular Underlying Index components on the performance of the Underlying Index and the availability of particular securities in the secondary market. However, the Fund may use replication to seek to achieve its investment objective if practicable. A replication strategy involves generally investing in all of the securities in the Underlying Index with the same weights as the Underlying Index. There may also be instances when the Adviser may choose to overweight another security in the Underlying Index or purchase (or sell) securities not in the Underlying Index, which the Adviser believes are appropriate to substitute for one or more Underlying Index components in seeking to accurately track the Underlying Index, such as: (i) regulatory requirements possibly affecting the Fund’s ability to hold a security in the Underlying Index or (ii) liquidity concerns possibly affecting the Fund’s ability to purchase or sell a security in the Underlying Index. In addition, from time to time, securities are added to or removed from the Underlying Index. The Fund may sell securities that are represented in the Underlying Index or purchase securities that are not yet represented in the Underlying Index in anticipation of their removal from or addition to the Underlying Index pursuant to scheduled reconstitutions and rebalancings of the Underlying Index. The Fund will concentrate its investments (i.e., invest 25% or more of its assets) in securities issued by companies whose principal business activities are in the same industry or group of industries to the extent the Underlying Index is so concentrated. As of May 31, 2017, the telecommunications, energy and consumer staples sectors each represented a substantial portion of the Underlying Index.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

100

Asset Class  Risk . The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk . If the Underlying Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries and the Fund’s performance will be particularly susceptible to adverse events impacting such industry.

Consumer Staples Sector Risk . Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk . The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Declining Yield Risk . During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Energy Sector Risk . The energy sector is often cyclical and highly dependent on commodities prices. Securities prices for companies in the energy sector may be affected by a variety of factors, including, among others, worldwide energy prices, exploration costs, energy conservation efforts, changes in currency exchange rates, government regulation and market, economic and political risks of the countries where energy companies are located or do business. The Fund may be adversely affected by negative developments relating to the energy sector and commodities issuers.

Extension Risk . During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Fluctuation of Yield and Liquidation Amount Risk . The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk . The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include risks associated with differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

High Yield and Unrated Securities Risk . High yield, below investment grade and unrated high risk debt securities (which also may be known as “junk bonds”) may present additional risks because these securities may be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, present more credit risk than investment grade bonds and subject to greater risk of default. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.

101

Income Risk . The Fund’s income may decline during a period of falling interest rates if the Fund holds floating or variable rate debt securities or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund’s shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk . Investments in fixed-income instruments are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s holdings and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects on the financial markets and the Fund’s investments. Fixed-income instruments with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk . The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk . It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Adviser for purposes of the Fund’s net asset value (“NAV”), causing the Fund to be less liquid and unable to realize what the Adviser believes should be the price of the investment. Valuation of Fund investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the historically low interest rate environment as of the date of this prospectus.

Market Price Risk . Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk . The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world. The performance of these investments may underperform the general securities markets or other types of securities.

Non-Diversification Risk . The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk . Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Underlying Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Underlying Index.

Prepayment Risk . Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

102

Regulatory and Legal Risk . U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators may pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund. These may impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

Restricted Securities Risk . Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.

Risk of Cash Transactions . In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Telecommunications Sector Risk . The telecommunications sector may be affected by extensive government regulation, industry competition and obsolescence of telecommunications products and services due to technological advancement. The Fund may be adversely affected by events or developments negatively impacting the telecommunications sector or issuers within the telecommunications sector.

Tracking Error Risk . The performance of the Fund may diverge from that of the Underlying Index for a number of reasons, including operating expenses, transaction costs, cash flows and operational inefficiencies. The Fund’s return also may diverge from the return of the Underlying Index because the Fund bears the costs and risks associated with buying and selling securities (especially when rebalancing the Fund’s securities holdings to reflect changes in the Underlying Index) while such costs and risks are not factored into the return of the Underlying Index. Transaction costs, including brokerage costs, will decrease the Fund’s NAV to the extent not offset by the transaction fee payable by an Authorized Participant. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. In addition, the Fund’s use of a representative sampling approach may cause the Fund’s returns 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. Errors in the Underlying Index data, the Underlying Index computations and/or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. In addition, the Fund may be unable to invest in certain securities included in the Underlying Index, or invest in them in the exact proportions in which they are represented in the Underlying Index, due to legal restrictions or limitations imposed by the governments of certain countries, a lack of liquidity in markets in which such securities trade, potential adverse tax consequences or other regulatory reasons. To the extent the Fund calculates its NAV based on fair value prices and the value of the Underlying Index is based on the securities’ closing prices (i.e., the value of the Underlying Index is not based on fair value prices), the Fund’s ability to track the Underlying Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities, and such sale may cause the Fund to realize a loss and, thus, the Fund’s performance to deviate from the performance of the Underlying Index. In light of the factors discussed above, the Fund’s return may deviate significantly from the return of the Underlying Index.

Performance

As of the date of this Prospectus, the Fund has not commenced operations and therefore does not have a performance history. Once available, the Fund’s performance information will be accessible on the Fund’s website at www.powershares.com and will provide some indication of the risks of investing in the Fund.

Management of the Fund

Investment Adviser.  Invesco PowerShares Capital Management LLC (the “Adviser”).

103

Portfolio Managers.  The following individuals are responsible jointly and primarily for the day-to-day management of the Fund’s portfolio:

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only with APs and only in large blocks of 100,000 Shares (each block of Shares is called a “Creation Unit”), or multiples thereof (“Creation Unit Aggregations”), in exchange for the deposit or delivery of a basket of securities and/or cash. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares may be purchased and sold only on a national securities exchange through brokers. Shares will be listed for trading on NYSE Arca, Inc. (the “Exchange”) and because the Shares will trade at market prices rather than NAV, Shares may trade at prices greater than NAV (at a premium), at NAV, or less than NAV (at a discount).

Tax Information

The Fund’s distributions will generally be taxable, typically as either ordinary income or long-term capital gain, unless you are invested through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account; in such cases, taxation will be deferred until assets are withdrawn from the plan. A sale of Shares may result in short- or long-term capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund’s distributor or its related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary’s web-site for more information.

104

Summary Information

Investment Objective

The PowerShares BulletShares 2025 High Yield Corporate Bond Portfolio (the “Fund”) seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of a high yield corporate bond index called the Nasdaq BulletShares ^® USD High Yield Corporate Bond 2025 Index (the “High Yield 2025 Index” or the “Underlying Index”).

Fund Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors may pay brokerage commissions on their purchases and sales of Shares, which are not reflected in the table or the example below.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. This example does not include the brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. At the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks investment results that correspond generally to the performance , before the Fund’s fees and expenses, of the High Yield 2025 Index. The High Yield 2025 Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of, as of August 31, 2017, approximately 161 high yield corporate bonds (which also may be known as “junk bonds”) with effective maturities in the year 2025. The High Yield 2025 Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated high yield

105

corporate bonds with effective maturities in the year 2025. The effective maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security is determined in accordance with a rules-based methodology developed by Accretive Asset Management, LLC (“Accretive” or the “Index Provider”). The actual maturity of a callable security may change because an issuer of a callable security may “call” or repay the amount owed under the security before its stated maturity. As of the date of this Prospectus, the expected duration of the High Yield 2025 Index, and thus of the Fund, is 5 to 8 years. Each year, as the Fund moves closer to its designated year of maturity, the Fund’s expected duration will become shorter. Accretive is affiliated with Invesco PowerShares Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Fund has a designated year of maturity of 2025 and will terminate on or about December 31, 2025. In connection with such termination, the Fund will make a cash distribution to then-current shareholders of its net assets after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount at maturity. The Fund will invest at least 80% of its total assets in component securities that comprise the Underlying Index. There are no minimum credit rating requirements for securities that the Fund may purchase; however, the Fund will not purchase securities that are in default. In the last twelve months of operation, when the bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2025 without requiring additional approval by the Board of Trustees (the “Board”) of PowerShares Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval if a majority of the Board determines the change to be in the best interest of the Fund. The Board may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Adviser uses quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that resemble the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, sector, duration and other financial characteristics of fixed income instruments. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular Underlying Index components on the performance of the Underlying Index and the availability of particular securities in the secondary market. However, the Fund may use replication to seek to achieve its investment objective if practicable. A replication strategy involves generally investing in all of the securities in the Underlying Index with the same weights as the Underlying Index. There may also be instances when the Adviser may choose to overweight another security in the Underlying Index or purchase (or sell) securities not in the Underlying Index, which the Adviser believes are appropriate to substitute for one or more Underlying Index components in seeking to accurately track the Underlying Index, such as: (i) regulatory requirements possibly affecting the Fund’s ability to hold a security in the Underlying Index or (ii) liquidity concerns possibly affecting the Fund’s ability to purchase or sell a security in the Underlying Index. In addition, from time to time, securities are added to or removed from the Underlying Index. The Fund may sell securities that are represented in the Underlying Index or purchase securities that are not yet represented in the Underlying Index in anticipation of their removal from or addition to the Underlying Index pursuant to scheduled reconstitutions and rebalancings of the Underlying Index. The Fund will concentrate its investments (i.e., invest 25% or more of its assets) in securities issued by companies whose principal business activities are in the same industry or group of industries to the extent the Underlying Index is so concentrated. As of August 31, 2017, the consumer staples and energy sectors represented a substantial portion of the Underlying Index.

Principal Risks of Investing in the Fund

The following summarizes the principal risks of the Fund.

The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

106

Asset Class  Risk . The securities in the Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors.

Concentration Risk . If the Underlying Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of Shares may rise and fall more than the value of Shares that invests in securities of companies in a broader range of industries and the Fund’s performance will be particularly susceptible to adverse events impacting such industry.

Consumer Staples Sector Risk . Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The Fund may be adversely affected by events or developments negatively impacting the consumer staples sector or issuers within the consumer staples sector.

Credit Risk . The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Declining Yield Risk . During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Energy Sector Risk . The energy sector is often cyclical and highly dependent on commodities prices. Securities prices for companies in the energy sector may be affected by a variety of factors, including, among others, worldwide energy prices, exploration costs, energy conservation efforts, changes in currency exchange rates, government regulation and market, economic and political risks of the countries where energy companies are located or do business. The Fund may be adversely affected by negative developments relating to the energy sector and commodities issuers.

Extension Risk . During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund’s income.

Fluctuation of Yield and Liquidation Amount Risk . The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk . The Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include risks associated with differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries and potential restrictions of the flow of international capital.

High Yield and Unrated Securities Risk . High yield, below investment grade and unrated high risk debt securities (which also may be known as “junk bonds”) may present additional risks because these securities may be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, present more credit risk than investment grade bonds and subject to greater risk of default. The price of high yield securities tends to be subject to greater volatility due to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.

107

Income Risk . The Fund’s income may decline during a period of falling interest rates if the Fund holds floating or variable rate debt securities or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that the Fund’s shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by the Fund to shareholders may be less.

Interest Rate Risk . Investments in fixed-income instruments are subject to the possibility that interest rates could rise sharply, causing the value of the Fund’s holdings and share price to decline. The risks associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects on the financial markets and the Fund’s investments. Fixed-income instruments with longer durations are subject to more volatility than those with shorter durations.

Issuer-Specific Changes Risk . The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk . It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Adviser for purposes of the Fund’s net asset value (“NAV”), causing the Fund to be less liquid and unable to realize what the Adviser believes should be the price of the investment. Valuation of Fund investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the historically low interest rate environment as of the date of this prospectus.

Market Price Risk . Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market.

Market Risk . The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world. The performance of these investments may underperform the general securities markets or other types of securities.

Non-Diversification Risk . The Fund is considered non-diversified because it may invest a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers and the Fund may experience greater losses and volatility than a more diversified portfolio.

Passive Management Risk . Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Underlying Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Underlying Index.

Prepayment Risk . Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, because issuers of the securities may be able to prepay the principal due on the securities. These securities generally offer less potential for gains when interest rates decline and may offer a greater potential for loss when interest rates rise.

108

Regulatory and Legal Risk . U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund. These regulations and laws impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

Restricted Securities Risk . Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.

Risk of Cash Transactions . In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF.

Tracking Error Risk . The performance of the Fund may diverge from that of the Underlying Index for a number of reasons, including operating expenses, transaction costs, cash flows and operational inefficiencies. The Fund’s return also may diverge from the return of the Underlying Index because the Fund bears the costs and risks associated with buying and selling securities (especially when rebalancing the Fund’s securities holdings to reflect changes in the Underlying Index) while such costs and risks are not factored into the return of the Underlying Index. Transaction costs, including brokerage costs, will decrease the Fund’s NAV to the extent not offset by the transaction fee payable by an Authorized Participant. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. In addition, the Fund’s use of a representative sampling approach may cause the Fund’s returns 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. Errors in the Underlying Index data, the Underlying Index computations and/or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. In addition, the Fund may be unable to invest in certain securities included in the Underlying Index, or invest in them in the exact proportions in which they are represented in the Underlying Index, due to legal restrictions or limitations imposed by the governments of certain countries, a lack of liquidity in markets in which such securities trade, potential adverse tax consequences or other regulatory reasons. To the extent the Fund calculates its NAV based on fair value prices and the value of the Underlying Index is based on the securities’ closing prices (i.e., the value of the Underlying Index is not based on fair value prices), the Fund’s ability to track the Underlying Index may be adversely affected. For tax efficiency purposes, the Fund may sell certain securities, and such sale may cause the Fund to realize a loss and, thus, the Fund’s performance to deviate from the performance of the Underlying Index. In light of the factors discussed above, the Fund’s return may deviate significantly from the return of the Underlying Index.

Performance

As of the date of this Prospectus, the Fund has not commenced operations and therefore does not have a performance history. Once available, the Fund’s performance information will be accessible on the Fund’s website at www.powershares.com and will provide some indication of the risks of investing in the Fund.

109

Purchase and Sale of Shares

The Fund will issue and redeem Shares at NAV only with APs and only in large blocks of 100,000 Shares (each block of Shares is called a “Creation Unit”), or multiples thereof (“Creation Unit Aggregations”), in exchange for the deposit or delivery of a basket of securities and/or cash. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.

Individual Shares may be purchased and sold only on a national securities exchange through brokers. Shares will be listed for trading on NYSE Arca, Inc. (the “Exchange”) and because the Shares will trade at market prices rather than NAV, Shares may trade at prices greater than NAV (at a premium), at NAV, or less than NAV (at a discount).

Tax Information

The Fund’s distributions will generally be taxable, typically as either ordinary income or long-term capital gain, unless you are invested through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account; in such cases, taxation will be deferred until assets are withdrawn from the plan. A sale of Shares may result in short- or long-term capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund’s distributor or its related companies may pay the intermediary for certain Fund-related activities, including those that are designed to make the intermediary more knowledgeable about exchange traded products, such as the Fund, as well as for marketing, education or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary’s web-site for more information.

Additional Information About the Funds’ Strategies and Risks

Principal Investment Strategies

Each Fund generally will invest at least 80% of its total assets in components of its respective Underlying Index. Each Fund operates as an index fund and is not actively managed. Each Fund uses an “indexing” investment approach to attempt to correspond, before fees and expenses, to the performance of its Underlying Index. The Adviser seeks correlation over time of 0.95 or better between a Fund’s performance and the performance of its Underlying Index; a figure of 1.00 would represent perfect correlation. Another means of evaluating the relationship between the returns of a Fund and its Underlying Index is to assess the “tracking error” between the two. Tracking error means the variation between a Fund’s annual return and the return of its Underlying Index, expressed in terms of standard deviation. Each Fund seeks to have a tracking error of less than 5%, measured on a monthly basis over a one-year period by taking the standard deviation of the difference in the Fund’s returns versus the Underlying Index’s returns. Because each Fund uses an indexing approach to try to achieve its investment objective, each Fund does not take temporary defensive positions during periods of adverse market, economic or other conditions.

Each Fund expects to use a sampling approach in seeking to achieve its investment objective. A “sampling” methodology means that the Adviser uses a quantitative analysis to select securities from an Underlying Index universe to obtain a representative sample of securities that have, in the aggregate, investment characteristics similar to the Underlying Index, respectively, in terms of key risk factors, performance attributes and other characteristics. These include maturity, credit quality, sector, duration and other financial characteristics of securities. When employing a sampling methodology, the Adviser bases the quantity of holdings in a Fund on a number of factors, including asset size of the Fund, and generally expects the Fund to hold less than the total number of securities in its Underlying Index. However, the Adviser reserves the right to invest a Fund in as many securities as it believes necessary to achieve the Fund’s investment objective.

There also may be instances in which the Adviser may choose to (i) overweight a security in an Underlying Index, (ii) purchase securities not contained in an Underlying Index that the Adviser believes are appropriate to substitute for certain securities in that Underlying Index, or (iii) utilize various combinations of other available investment techniques in seeking to track an Underlying Index.

Each Fund may sell securities included in an Underlying Index in anticipation of their removal from the Underlying Index, or purchase securities not included in an Underlying Index in anticipation of their addition to the Underlying Index.

Additional information about the construction of each Fund’s Underlying Index is set forth below.

Each Investment Grade Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated investment-grade corporate bonds with effective maturities in the same calendar year. The effective maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security as determined in accordance with a rules-based methodology developed by Accretive. While the Index Provider does not target a specific duration, the Index Provider currently expects that each Investment Grade Index would have a weighted average duration that is approximately the midpoint of the Investment Grade Index’s target maturity year. Duration is expressed as a number of years and is a measure of a fixed income security’s sensitivity to changes in interest rates.

Each High Yield Index is designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated high yield corporate bonds with effective maturities in the same calendar year. The effective maturity of an eligible corporate bond is determined by its actual maturity or, in the case of callable securities, the effective maturity of the security as determined in accordance with a rules-based methodology developed by Accretive.

Principal Risks of Investing in the Funds

The following provides additional information regarding certain of the principal risks identified under “Principal Risks of Investing in the Fund” in each Fund’s “Summary Information” section.

114

Asset Class Risk

The securities in a Fund’s portfolio may underperform the returns of other securities or indices that track other industries, markets, asset classes or sectors. Different types of securities and indices tend to go through different performance cycles than the general securities market.

Concentration Risk

If a Fund’s Underlying Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of a Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries and a Fund’s performance will be particularly susceptible to adverse events impacting such industry.

Consumer Discretionary Sector Risk

The success of consumer product manufacturers and retailers is tied closely to the performance of the overall domestic and international economy, exchange and interest rates, competitive and consumer confidence. Success depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products in the marketplace.

Consumer Staples Sector Risk

Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. Companies in the consumer staples sector are also affected by changes in government regulation, global economic, environmental and political events, economic conditions and the depletion of resources. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The prices of raw materials fluctuate in response to a number of factors, including, without limitation, changes in government agricultural support programs, exchange rates, import and export controls, changes in international agricultural and trading policies, and seasonal and weather conditions.

Credit Risk

A Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a transaction (such as a repurchase agreement or a loan of portfolio securities) is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. If an issuer fails to pay interest, a Fund’s income would likely be reduced, and if an issuer fails to repay principal, the value of the instrument likely would fall and the Fund could lose money. This risk is especially acute with respect to high yield, below investment grade and unrated high risk debt instruments (which also may be known as “junk bonds”). Also, the issuer, guarantor or counterparty may suffer adverse changes in its financial condition that could lower the credit quality (or the market’s perception of the credit quality) of an issuer or instrument, leading to greater volatility in the price of the instrument and in shares of a Fund. Although credit quality may not accurately reflect the true credit risk of an instrument, a change in the credit quality rating of an instrument or an issuer can have a rapid, adverse effect on the instrument’s liquidity and make it more difficult for a Fund to sell at an advantageous price or time. Any applicable limitation on the credit quality of an issuer or instrument in which a Fund may invest is applied at the time the Fund purchases the instrument.

The degree of credit risk depends on the particular instrument and the financial condition of the issuer, guarantor or counterparty, which are often reflected in its credit quality. Credit quality is a measure of the issuer’s expected ability to make all required interest and principal payments in a timely manner. An issuer with the highest credit rating has a very strong capacity with respect to making all payments. An issuer with the second-highest credit rating has a strong capacity to make all payments, but the degree of safety is somewhat less. An issuer with the lowest credit quality rating may be in default or have extremely poor prospects of making timely payment of interest and principal. Credit ratings assigned by rating agencies are based on a number of factors and subjective judgments and therefore do not necessarily represent an issuer’s actual financial condition or the volatility or liquidity of the security. Although higher-rated securities generally present lower credit risk as compared to lower-rated or unrated securities, an issuer with a high credit rating may in fact be exposed to heightened levels of credit or liquidity risk. See Appendix A of the SAI for a more complete discussion of the meaning of the different credit quality ratings.

115

Investment grade instruments are fixed-income instruments that have been determined by a nationally recognized statistical rating organization to have a medium to high probability of being paid (although there is always a risk of default) or if unrated, have been determined by the Adviser to be of comparable quality. Investment grade instruments are designated “BBB”, “A”, “AA” or “AAA” by S&P, Fitch, DBRS Ltd., Morningstar Credit Ratings, LLC and Kroll Bond Rating Agency, Inc., “Baa”, “A”, “Aa” or “Aaa” by Moody’s, and “bbb”, “a”, “aa”, or “aaa” by A.M. Best Company, or an equivalent rating by any other nationally recognized statistical rating organization, or have been determined by the Adviser to be of comparable quality. If nationally recognized statistical rating organizations assign different ratings to the same instrument, a Fund will use the higher rating for purposes of determining the instrument’s credit quality. The Adviser’s credit analysis includes looking at factors such as an issuer’s debt service coverage (i.e., its ability to make interest payments on its debt), the issuer’s cash flow, general economic factors and domestic and global market conditions.

Declining Yield Risk

During the final year of a Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.

Energy Sector Risk

The energy sector is often cyclical and highly dependent on commodities prices. Securities prices for companies in the energy sector may be affected by a variety of factors related to worldwide energy prices, exploration costs, energy conservation efforts and production spending. The performance of these companies and the prices of these securities are subject to changes in currency exchange rates, government regulation, world events and weather, depletion of natural resources and economic conditions, as well as market, economic and political risks of the countries where energy companies are located or do business. Securities of energy companies may be subject to swift price and supply fluctuations as a result of these events, which may adversely affect the Funds. Oil and gas exploration and production can be significantly affected by natural disasters. Companies in the energy sector may be at an increased risk of civil liability and environmental damage claims, and are also subject to the risk of loss from terrorism.

Extension Risk

An issuer may exercise its right to pay principal on an obligation later than expected, thereby effectively lengthening the maturity of the obligation and making the obligation more sensitive to interest rate changes. This may happen when there is a rise in interest rates. Under these circumstances, the value of the obligation will decrease and a Fund’s performance may suffer from its inability to invest in higher yielding securities.

Financial Sector Risk

The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. Financial services companies are subject to extensive governmental regulation which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Profitability is largely dependent on the availability and cost of capital funds, and can fluctuate significantly when interest rates change or due to increased competition. A Fund may be adversely affected by events or developments negatively impacting the financial sector. For example, events in the financial sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur losses.

116

Fluctuation of Yield and Liquidation Amount Risk

A Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during a Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in a Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon a Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Foreign Issuers Risk

A Fund may invest in U.S. registered, dollar-denominated bonds of foreign corporations, which have different risks than investing in U.S. companies. These include risks associated with differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries, and potential restrictions of the flow of international capital. Foreign companies may be subject to less governmental regulation than U.S. issuers. Moreover, individual foreign economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rate of inflation, capital investment, resource self-sufficiency and balance of payment options.

High Yield and Unrated Securities Risk

High yield debt securities in the lower rating (higher risk) categories of the recognized rating services are commonly referred to as “junk bonds.” High yield securities are debt securities that have been determined by a rating agency to have a lower probability of being paid and have a credit rating of “BB” category or lower by S&P and Fitch or “Ba” category or lower by Moody’s or have been determined by the Adviser to be of comparable quality. The total return and yield of junk bonds can be expected to fluctuate more than the total return and yield of higher-quality bonds. Junk bonds (those rated below investment grade or in default, or unrated securities determined to be of comparable quality) are regarded as predominantly speculative with respect to the issuer’s continuing ability to meet principal and interest payments. High yield securities may be subject to greater levels of credit risk and tend to be less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time and may involve greater transactions costs and wider bid/ask spreads, than higher-quality bonds. The risks associated with high yield securities are heightened during times of weakening economic conditions or rising interest rates. Successful investment in lower-medium and lower-rated debt securities involves greater investment risk and is highly dependent on the Adviser’s credit analysis. The value of high yield securities is particularly vulnerable to changes in interest rates and a real or perceived economic downturn or higher interest rates could cause a decline in high-yield bond prices by lessening the ability of issuers to make principal and interest payments. These bonds are often thinly traded or subject to irregular trading and can be more difficult to sell and value accurately than higher-quality bonds because there tends to be less public information available about these securities. Because objective pricing data may be less available, judgment may play a greater role in the valuation process. In addition, the entire high yield bond market can experience sudden and sharp price swings due to a variety of factors, including changes in economic forecasts, stock market activity, large or sustained sales by major investors, a high-profile default, or just a change in the market’s psychology. High yield securities may be more sensitive to adverse market developments than higher-quality bonds. This type of volatility is usually associated more with stocks than bonds.

Income Risk

A Fund’s income may decline during a period of falling interest rates if the Fund holds floating or variable rate debt securities or when the Fund experiences defaults on debt securities it holds. The amount and rate of distributions that a Fund’s shareholders receive are affected by the income that the Fund receives from its portfolio holdings. If the income is reduced, distributions by a Fund to shareholders may be less.

117

Interest Rate Risk

Investments in fixed-income instruments are subject to the possibility that interest rates could rise (or are expected to rise) sharply, causing the value of a Fund’s holdings and share price to decline. Longer term bonds and zero coupon bonds are generally more sensitive to interest rate changes than shorter-term bonds. Generally, the longer the average duration of the bonds in a Fund, the more the Fund’s share price will fluctuate in response to interest rate changes. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates that incorporates a security’s yield, coupon, final maturity and call features, among other characteristics. For example, the price of a bond fund with an average duration of eight years would be expected to fall approximately 8% if interest rates rose by one percentage point. Conversely, the price of a bond fund with an average duration of negative three years would be expected to rise approximately 3% if interest rates rose by one percentage point. However, duration may not accurately reflect the true interest rate sensitivity of instruments held by a Fund and, in turn, a Fund’s susceptibility to changes in interest rates. If an issuer calls or redeems an investment or it matures during a time of declining interest rates, a Fund might have to reinvest the proceeds in an investment offering a lower yield, and therefore might not benefit from any increase in value as a result of declining interest rates.

Securities with floating interest rates generally are less sensitive to interest rate changes, but may decline in value if their interest rates do not rise as much or as fast as interest rates in general. In a decreasing interest rate environment, a Fund’s investment in securities with floating interest rates may prevent the Fund from taking full advantage of decreasing interest rates in a timely manner. During periods of rising interest rates, issuers of debt securities or asset-backed securities may pay principal later or more slowly than expected, which may reduce the value of a Fund’s investment in such securities and may prevent the Fund from receiving higher interest rates on proceeds reinvested.

Changing Fixed-Income Market Conditions

Although the Board of Governors of the Federal Reserve System (“Federal Reserve”) has started to raise interest rates, interest rates in the U.S. and many parts of the world, including certain European countries, remain at or near historically low levels. In addition, certain European countries have recently experienced (or currently are expected to experience) negative interest rates on certain fixed-income instruments, and similar interest rate conditions may be experienced in other regions. To the extent the Federal Reserve continues to raise interest rates, there is a risk that rates across the financial system may rise. Very low or negative interest rates may magnify a Fund’s susceptibility to interest rate risk and diminish yield and performance (e.g., during periods of very low or negative interest rates, a Fund may be unable to maintain positive returns).

Changes in fixed-income market conditions, including the recent increase and potential for future increases to the federal funds rate or interest rates falling below zero, may expose fixed-income markets to heightened volatility and reduced liquidity for certain Series investments that may be difficult to sell at favorable prices to meet fund redemption obligations, causing the value of a Fund’s investments and share price to decline. A rise in general interest rates may also result in increased redemptions from a Fund. Very low or changing interest rates may also have unpredictable effects on securities markets in general, directly or indirectly impacting a Fund’s investments, yield and performance. Thus, a Fund currently faces a heightened level of interest rate, liquidity and valuation risks.

Issuer-Specific Changes Risk

The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than those of larger issuers.

Liquidity and Valuation Risk

It may be difficult for a Fund to purchase and sell particular investments within a reasonable time at a favorable price. In particular, Rule 144A securities may become illiquid under adverse market or economic conditions and/or due to specific adverse changes in the condition of a particular issuer. The

118

capacity of traditional fixed-income market makers has not kept pace with the consistent growth in the fixed-income markets over the past three decades, which has led to reduced levels in the capacity of these market makers to engage in fixed-income trading and, as a result, dealer inventories of corporate fixed-income instruments are at or near historic lows relative to market size. These factors may apply more strongly with respect to high yield fixed-income instruments than higher quality fixed-income instruments. Market makers tend to provide stability and liquidity to debt-securities markets through their intermediary services, and their reduced capacity and number could lead to decreased liquidity and increased volatility in the fixed-income markets. The Fund’s ability to sell an instrument under favorable conditions also may be negatively impacted by, among other things, other market participants selling the same or similar instruments at the same time.

To the extent that there is not an established liquid market for instruments in which a Fund may invest, or there is a reduced number or capacity of traditional “market makers” with respect to debt instruments, trading in such instruments may be relatively inactive or irregular. In addition, during periods of reduced market liquidity, market turmoil or in the absence of readily available market quotations for particular investments in the Fund’s portfolio, the ability of the Fund to assign an accurate daily value to these investments may be difficult and the Adviser may be required to fair value the investments. Fair value determinations are inherently subjective and reflect good faith judgments based on available information. Accordingly, there can be no assurance that the determination of a security’s fair value in accordance with the Funds’ valuation procedures will in fact approximate the price at which a Fund could sell that security at that time (i.e., the sale price could differ, sometimes significantly, from the Fund’s last valuation for the security). The Funds (or the Adviser) rely on various sources of information to value investments and calculate NAV. The Funds may obtain pricing information from third parties that are believed to be reliable. In certain cases, this information may be unavailable or this information may be inaccurate because of errors by the third parties, technological issues, absence of current market data, or otherwise. As a result, the Funds’ ability to effectively value investments or calculate NAV may be adversely affected. These risks may be magnified in a rising interest rate environment and, if the Funds hold a significant percentage of fair valued or otherwise difficult to value securities, it may be particularly susceptible to the risks associated with valuation. For additional information about valuation determinations, see “Pricing Fund Shares.” Proportions of a Fund’s investments that are fair valued or difficult to value vary from time to time. Each Fund’s shareholder reports contain detailed information about the Fund’s holdings that are fair valued or difficult to value, including values of these holdings as of the dates of the reports. Investors should consider consulting these reports for detailed information.

Market Price Risk

Shares are listed for trading on NYSE Arca and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. Differences between secondary market prices and the value of the Funds’ holdings may be due largely to supply and demand forces in the secondary market, which may not be the same forces as those influencing prices for securities held by the Fund at a particular time. The Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market. Given the fact that Shares can be created and redeemed in Creation Units, the Adviser believes that large discounts or premiums to the NAV of Shares should not be sustained in the long-term. However, a Fund may have a limited number of financial institutions that may act as “Authorized Participants” or market markers. Only Authorized Participants who have entered into agreements with a Fund’s distributor may engage in creation or redemption transactions directly with the Fund (as described under “How to Buy and Sell Shares”). If those Authorized Participants exit the business or are unable to process creation and/or redemption orders (including in situations where Authorized Participants have limited or diminished access to capital required to post collateral), and no other Authorized Participant is able to step forward to create and redeem in either of these cases, Shares may trade at a discount to NAV like closed-end fund shares (and

119

may even face delisting). Similar effects may result if market makers exit the business or are unable to continue making markets in Shares. Further, while the creation/redemption feature is designed to make it likely that Shares normally will trade at prices closely correlated to a Fund’s next calculated NAV, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants or market participants, or during periods of significant market volatility, among other factors, may result in market prices that differ significantly from NAV. Although market makers will generally take advantage of differences between the NAV and the market price of Shares through arbitrage opportunities, there is no guarantee that they will do so. Further, the securities held by a Fund may be traded in markets that close at a different time than the NYSE Arca. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when NYSE Arca is open but after the applicable market closing, fixing or settlement times, bid-ask spreads and the resulting premium or discount to Shares’ NAV is likely to widen. In addition, secondary markets may be subject to irregular trading activity, wide bid-ask spreads and extended trade settlement periods, which could cause a material decline in the NAV and/or market prices for Shares. The bid-ask spread is generally larger during periods of lower than regular trading volume in Shares or reduced market liquidity and can increase significantly during periods of market disruption or steep declines, which may be the time an investor most wants to sell its Shares. During such periods, shareholders may be unable to sell Shares or may incur significant losses if Shares are sold. There are various methods by which investors can purchase and sell Shares and various orders that may be placed. Investors should consult their financial intermediary before purchasing or selling Shares. A Fund’s bid-ask spread may also be impacted by the liquidity of the underlying securities held by the Fund, particularly for newly launched or smaller funds or in instances of significant volatility of the underlying securities. A Fund’s investment results are measured based upon the daily NAV of Shares. Investors purchasing and selling Shares in the secondary market may not experience investment results consistent with those experienced by Authorized Participants creating and redeeming directly with a Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on NYSE Arca and may, therefore, have a material effect on the market price of Shares.

Market Risk

The value of, or income generated by, the securities held by a Fund are subject to the possibility of rapid and unpredictable fluctuation. The value of certain securities (e.g., equity securities) tends to fluctuate more dramatically over the shorter term than do the value of other asset classes. These movements may result from factors affecting individual companies, or from broader influences, including real or perceived changes in prevailing interest rates, changes in inflation or expectations about inflation, investor confidence or economic, political, social or financial market conditions that may be temporary or last for extended periods. Different sectors, industries and security types may react differently to such developments and, when the market performs well, there is no assurance that the securities held by a Fund will increase in value along with the broader markets. For example, the value of a Fund’s investments in securities or other instruments may be particularly susceptible to changes in commodity prices. As a result, a change in commodity prices may adversely affect a Fund’s investments. Volatility of financial markets can expose a Fund to greater market risk, possibly resulting in reduced liquidity. Moreover, changing economic, political, social or financial market conditions in one country or geographic region could adversely affect the market value of the securities held by a Fund in a different country or geographic region because of the increasingly interconnected global economies and financial markets. The Adviser potentially will be prevented from executing investment transactions at an advantageous time or price as a result of any domestic or global market disruptions, particularly disruptions causing heightened market volatility and reduced market liquidity. Changes or disruptions in market conditions also may lead to increased regulation of a Fund and the instruments in which a Fund may invest, which may, in turn, affect the Fund’s ability to pursue its investment objective and the Fund’s performance. In general, the securities or other instruments represented in a Fund’s Underlying Index or in which a Fund seeks to invest may be unavailable entirely or in the specific quantities sought by the Fund. As a result, a Fund may need to obtain the desired exposure through a less advantageous investment or forgo the investment at the time. This may adversely affect a Fund and increase the Fund’s index tracking error.

Non-Diversification Risk

A non-diversified Fund may hold larger positions in a smaller number of securities than a diversified fund. As a result, a non-diversified Fund’s performance may depend on the performance of a small number of

120

issuers and the Fund may be more susceptible to risks associated with and adverse developments affecting a single issuer, including changes in the market value of the issuer’s securities and unfavorable market and economic developments. These events could cause a greater impact on a non-diversified Fund’s NAV and total return (e.g., greater losses) and volatility than a more diversified portfolio.

Passive Management Risk

Unlike many investment companies, the Funds are not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble or defaulted on its obligations under the security, or whose credit rating was downgraded, unless that security is removed from the Underlying Index. In addition, a Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Underlying Index.

Prepayment Risk

The issuers of securities held by a Fund may be able to prepay principal due on the securities, particularly during periods of declining interest rates. Securities subject to prepayment risk generally offer less potential for gains when interest rates decline, and may offer a greater potential for loss when interest rates rise. In addition, rising interest rates may cause prepayments to occur at a slower than expected rate, thereby effectively lengthening the maturity of the security and making the security more sensitive to interest rate changes as well as limiting the ability of a Fund to invest in securities with higher interest rates. Prepayment risk is a major risk of certain asset-backed securities, including mortgage-backed securities.

Most floating rate fixed-income securities allow for prepayment of principal without penalty. Accordingly, the potential for the value of a floating rate security to increase in response to interest rate declines is limited. Fixed-income securities purchased to replace a prepaid security may have lower yields than the yield on the prepaid security.

Regulatory and Legal Risk

U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators pass new laws that affect the investments held by a Fund, the strategies used by a Fund or the level of regulation or taxation applying to a Fund. These regulations and laws impact the investment strategies, performance, costs and operations of a Fund, as well as the way investments in, and shareholders of, a Fund are taxed. The SEC recently adopted rules intended to limit, assess and manage liquidity risk. In the future, the rules may materially affect the securities in which a Fund invests and a Fund’s investment strategies and performance, as well as a Fund’s index tracking error.

Restricted Securities Risk

Restricted securities cannot be sold to the public without registration under the Securities Act of 1933, as amended (“1933 Act”). Unless registered for sale, restricted securities can be sold only in privately negotiated transactions or pursuant to an exemption from registration. Restricted securities may be considered illiquid and, therefore, are subject to a Fund’s limitation on illiquid securities.

Restricted securities may involve a high degree of business and financial risk, which may result in substantial losses. The securities may be less liquid than publicly traded securities. Although these securities may be resold in privately negotiated transactions, the prices realized from these sales could be less than those originally paid by a Fund. A Fund may invest in restricted securities, including securities initially offered and sold without registration pursuant to Rule 144A under the 1933 Act (“Rule 144A Securities”) and securities of U.S. and non-U.S. issuers initially offered and sold outside the United States without registration with the SEC pursuant to Regulation S under the Securities Act (“Regulation S Securities”) under the 1933 Act. Rule 144A Securities and Regulation S Securities generally may be traded freely among certain qualified institutional investors, such as a Fund, and non-U.S. persons, but resale to a broader base of investors in the United States may be permitted only in significantly more limited circumstances.

Investing in Rule 144A Securities and other restricted and non-registered securities (such as privately placed securities purchased through transactions complying with the requirements in Regulation D or S under the Securities Act) could have the effect of increasing the amount of a Fund’s assets invested in illiquid securities to the extent that qualified institutional buyers become uninterested, for a time, in purchasing these securities.

121

Risk of Cash Transactions

In certain instances, unlike most ETFs, a Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in a Fund may be less tax-efficient than an investment in a more conventional ETF. ETFs generally are able to make in-kind redemptions and avoid being taxed on gain on the distributed portfolio securities at the Fund level. Because a Fund may effect redemptions for cash, rather than in-kind distributions, it may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. If a Fund recognizes gain on these sales, this generally will cause the Fund to recognize gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if it were to distribute portfolio securities in-kind. A Fund generally intends to distribute these gains to shareholders to avoid being taxed on this gain at the Fund level and otherwise comply with the special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than, if they had made an investment in a different ETF. Moreover, cash transactions may have to be carried out over several days if the securities market is relatively illiquid and may involve considerable brokerage fees and taxes. These brokerage fees and taxes, which will be higher than if a Fund sold and redeemed its Shares principally in-kind, will be passed on to purchasers and redeemers of Creation Units in the form of creation and redemption transaction fees. In addition, these factors may result in wider spreads between the bid and the offered prices of a Fund’s Shares than for more conventional ETFs.

Telecommunications Sector Risk

The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals or the enactment of new adverse regulatory requirements may adversely affect the business of the telecommunications companies. The telecommunications sector can also be significantly affected by intense competition, including competition with alternative technologies such as wireless communications, product compatibility, consumer preferences, rapid obsolescence and research and development of new products. Other risks include those related to regulatory changes, such as the uncertainties resulting from such companies’ diversification into new domestic and international businesses, as well as agreements by any such companies linking future rate increases to inflation or other factors not directly related to the actual operating profits of the enterprise.

Tracking Error Risk

Each Fund’s return may not match the return of its Underlying Index for a number of reasons. For example, a Fund incurs a number of operating expenses not applicable to its Underlying Index and incurs costs associated with buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of its Underlying Index, which are not factored into the return of its Underlying Index. Transaction costs, including brokerage costs, will decrease a Fund’s NAV to the extent not offset by the transaction fee payable by an AP. Market disruptions and regulatory restrictions could have an adverse effect on a Fund’s ability to adjust its exposure to the required levels in order to track its Underlying Index. There is no assurance that the Index Provider or any agents that may act on its behalf will compile a Fund’s Underlying Index accurately, or that each Underlying Index will be determined, composed or calculated accurately. Errors in respect of the quality, accuracy and completeness of the data used to compile an Underlying Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, particularly where the indices are less commonly used as benchmarks by funds or managers. Therefore, gains, losses or costs associated with errors of the Index Provider or its agents will generally be borne by the applicable Fund and its shareholders. For example, during a period where a Fund’s Underlying Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Underlying Index’s other constituents. Such errors may negatively or positively impact the Funds and their shareholders. Any gains due to the Index Provider’s or others’ errors will be kept by the Funds and their shareholders and any losses resulting from the Index Provider’s or others’ errors will be borne by the applicable Fund and its shareholders. Imperfect correlation between a Fund’s portfolio securities and those in its Underlying Index, rounding of prices, changes to the Underlying Index and regulatory

122

requirements may cause tracking error, the divergence of the Fund’s performance from that of its Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses while its Underlying Index does not. If a Fund utilizes a representative sampling indexing strategy, the Fund may experience higher tracking error than it would if it held all the securities of its Underlying Index with the same weightings as the Underlying Index. In addition, a Fund may be unable to invest in certain securities and other instruments included in its Underlying Index, or invest in them in the exact proportions they represent of its Underlying Index, due to legal restrictions or limitations (imposed by the governments of certain countries), or a lack of liquidity in markets in which such securities trade, potential adverse tax consequences or other regulatory reasons (such as diversification requirements). Moreover, a Fund may be delayed in purchasing or selling securities and other instruments included in its Underlying Index. For tax efficiency purposes, a Fund may sell certain securities, and such sale may cause the Fund to realize a loss and, thus, the Fund’s performance to deviate from the performance of its Underlying Index.

Each Fund may fair value certain of its securities (including foreign securities and/or underlying currencies it holds), except those securities primarily traded on exchanges that close at the same time the Fund calculates its NAV. Fair value pricing involves subjective judgments and it is possible that a fair value determination for a security or other asset is materially different from the value that could be realized upon the sale of such security or asset. In addition, fair value pricing could result in a difference between the prices used to calculate a Fund’s NAV and the prices used by such Fund’s Underlying Index. To the extent each Fund calculates its NAV based on fair value prices and the value of its Underlying Index is based on securities’ closing prices on local foreign markets (i.e., the value of its Underlying Index is not based on fair value prices), or if a Fund otherwise calculates its NAV based on prices that differ from those used in calculating its Underlying Index, the Fund’s ability to track its Underlying Index may be adversely affected. The need to comply with the tax diversification and other requirements of the Internal Revenue Code may also impact a Fund’s ability to replicate the performance of its Underlying Index. In addition, if a Fund utilizes depositary receipts and other derivative instruments that are not included in its Underlying Index, its return may not correlate as well with the returns of its Underlying Index as would be the case if the Fund purchased all the securities in its Underlying Index directly. Actions taken in response to proposed corporate actions could result in increased tracking error. In light of the factors discussed above, a Fund’s return may deviate significantly from the return of its Underlying Index.

Non-Principal Investment Strategies

As non-principal investment strategies, each Fund may invest up to 20% of its total assets in securities not included in its respective Underlying Index, money market instruments, including repurchase agreements or money market funds, convertible securities, structured notes (notes on which the amount of principal repayment and interest payments are based on the movement of one or more specified factors, such as the movement of a particular bond or bond index) and in swaps, options and futures contracts. Swaps, options and futures contracts (and convertible securities and structured notes) may be used by each Fund in seeking performance that corresponds generally to its respective Underlying Index (whether by gaining exposure to the Underlying Index as a whole or to certain specific Underlying Index components in lieu of the Fund holding such Underlying Index components directly), and in managing cash flows, but will not be used for hedging purposes. The Adviser anticipates that it may take approximately three business days (i.e., each day the NYSE Arca is open) for additions and deletions to a Fund’s Underlying Index to be reflected in the portfolio composition of a Fund.

In accordance with 1940 Act rules, each Fund has adopted a policy to invest at least 80% of the value of its net assets, plus the amount of any borrowings for investment purposes, in the types of securities (e.g., corporate bonds or high yield securities, which are debt securities that are rated below investment grade by nationally recognized statistical rating organizations or are unrated securities that the Adviser believes are of comparable quality) suggested by the Fund’s name (an “80% investment policy”). Each Fund considers the securities suggested by its name to be those securities that comprise the Underlying Index. Therefore, each Fund anticipates meeting its 80% investment policy because it already is required to invest at least 80% of its total assets in securities that comprise the Underlying Index, in accordance with its principal investment strategies and the terms of the Trust’s exemptive relief.

123

Each of the investment policies described herein, including each Fund’s investment objective and 80% investment policy, constitutes a non-fundamental policy that the Board of Trustees (the “Board”) of the Trust may change without shareholder approval upon 60 days’ prior written notice to shareholders. The fundamental and non-fundamental policies of the Funds are set forth in the Trust’s Statement of Additional Information (“SAI”) under the section “Investment Restrictions.”

Borrowing Money

Each Fund may borrow money from a bank up to a limit of 10% of the value of its assets, but only for temporary or emergency purposes.

Additional Risks of Investing in the Funds

The following provides additional risk information regarding investing in the Funds.

Trading Issues

Investors buying or selling Shares in the secondary market may pay brokerage commissions or other charges, which may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. Moreover, trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of a Fund will continue to be met or will remain unchanged.

Index Provider Risk

Each Fund seeks to achieve returns that generally correspond, before fees and expenses, to the performance of its Underlying Index, as published by an Index Provider. There is no assurance that an Index Provider will compile an Underlying Index accurately, or that an Underlying Index will be determined, composed or calculated accurately. While each Index Provider gives descriptions of what an Underlying Index is designed to achieve, an Index Provider generally does not provide any warranty or accept any liability in relation to the quality, accuracy or completeness of data in such indices, and it generally does not guarantee that an Underlying Index will be in line with its methodology. Errors made by an Index Provider with respect to the quality, accuracy and completeness of the data within an Underlying Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time, if at all. Therefore, gains, losses or costs associated with Index Provider errors will generally be borne by the Fund and its shareholders.

Index Rebalancing Risk

Pursuant to the methodology that an Index Provider uses to calculate and maintain an Underlying Index, a security may be removed from a Fund’s Underlying Index in the event that it does not comply with the eligibility requirements of the Underlying Index. As a result, the Fund may be forced to sell securities at inopportune times or for prices other than at current market values or may elect not to sell such securities on the day that they are removed from the Underlying Index, due to market conditions or otherwise. Due to these factors, the variation between the Fund’s annual return and the return of its Underlying Index may increase significantly.

Apart from scheduled rebalances, the Index Provider may carry out additional ad hoc rebalances to an Underlying Index, for example, to correct an error in the selection of constituents. When the Fund in turn rebalances its portfolio, any transaction costs and market exposure arising from such portfolio rebalancing will be borne by the Fund and its shareholders. Unscheduled rebalances also expose the Fund to additional tracking error risk. Therefore, errors and additional ad hoc rebalances carried out by the Index Provider may increase the Fund’s costs and market exposure.

124

Shares May Trade at Prices Different than NAV

The NAV of the Shares generally will fluctuate with changes in the market value of the Fund’s holdings. The market prices of Shares generally will fluctuate in accordance with changes in NAV, as well as the relative supply of and demand for Shares on the Exchange. The Adviser cannot predict whether the Shares will trade below, at or above the Fund’s NAV. Price differences may be due largely to the fact that supply and demand forces at work in the secondary trading market for the Shares will be related, but not identical, to the same forces influencing the prices of the components of the Fund’s Underlying Index trading individually or in the aggregate at any point in time. In addition, disruptions to creations and redemptions or the existence of extreme market volatility may result in trading prices that differ significantly from NAV. If a shareholder purchases at a time when the market price is at a premium to the NAV or sells at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Money Market Funds Risk

Money market funds are subject to management fees and other expenses, and the Fund’s investments in money market funds will cause it to bear proportionately the costs incurred by the money market funds’ operations while simultaneously paying its own management fees and expenses. An investment in a money market fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency; it is possible to lose money by investing in a money market fund. To the extent that the Fund invests in money market funds, the Fund will be subject to the same risks that investors experience when investing in money market funds. These risks may include the impact of significant fluctuations in assets as a result of the cash sweep program or purchase and redemption activity in those funds.

Money market funds are open-end registered investment companies that historically have traded at a stable $1.00 per share price. However, under recent amendments to money market fund regulations under the 1940 Act, money market funds that do not meet the definition of a “retail money market fund” or “government money market fund” are required to transact at a floating NAV per share (i.e., in a manner similar to how all other non-money market mutual funds transact), instead of at a $1.00 stable share price. Those rule amendments also permit money market funds to impose liquidity fees and redemption gates for use in times of market stress. If the Fund invested in a money market fund with a floating NAV, the impact on the trading and value of the money market instrument as a result of the rule amendments may negatively affect the Fund’s return potential.

Derivatives Risk

Derivatives may pose risks in addition to and greater than those associated with investing directly in securities, currencies or other investments, including risks relating to leverage, imperfect correlations with underlying investments or a Fund’s other portfolio holdings, high price volatility, lack of availability, counterparty credit, liquidity, valuation and legal restrictions. For derivatives traded on an exchange or through a central counterparty, a Fund is subject to the credit risk of the clearing broker or clearinghouse. Their use is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If the Adviser is incorrect about its expectations of market conditions, the use of derivatives could also result in a loss, which in some cases may be unlimited. Some of the derivatives in which a Fund invests are traded (and privately negotiated) in the over-the-counter (“OTC”) market. OTC derivatives are subject to heightened credit, liquidity and valuation risks. Certain risks also are specific to the derivatives in which a Fund invests.

Swap Agreements Risk

Swap agreements are contracts among a Fund and a counterparty to exchange the return of the pre-determined underlying investment (such as the rate of return of the underlying index). Swap agreements may be negotiated bilaterally and traded OTC between two parties or, in some instances, must be transacted through a futures commission merchant or swap execution facility and cleared through a clearinghouse that serves as a central counterparty. Risks associated with the use of swap agreements are different from those associated with ordinary portfolio securities

125

transactions, due in part to the fact they could be considered illiquid and many swaps trade on the OTC market. Swaps are particularly subject to counterparty credit, correlation, valuation, liquidity and leveraging risks. Certain standardized swaps are subject to mandatory central clearing. Central clearing is intended to reduce counterparty credit risk and increase liquidity, but central clearing does not make swap transactions risk-free.

Futures Contracts Risk

Futures contracts are typically exchange-traded contracts that call for the future delivery of an asset at a certain price and date, or cash settlement of the terms of the contract. Risks of futures contracts may be caused by an imperfect correlation between movements in the price of the instruments and the price of the underlying securities. In addition, there is the risk that a Fund may not be able to enter into a closing transaction because of an illiquid market. Exchanges can limit the number of positions that can be held or controlled by a Fund or the Adviser, thus limiting the ability to implement the Fund’s strategies. Futures markets are highly volatile and the use of futures may increase the volatility of a Fund’s NAV. Futures are also subject to leverage risks and to liquidity risk.

Options Risk

Options or options on futures contracts give the holder of the option the right to buy (or to sell) a position in a security or in a contract to the writer of the option, at a certain price. They are subject to correlation risk because there may be an imperfect correlation between the options and the securities markets that cause a given transaction to fail to achieve its objectives. The successful use of options depends on the Adviser’s ability to predict correctly future price fluctuations and the degree of correlation between the options and securities markets. Exchanges can limit the number of positions that can be held or controlled by a Fund or the Adviser, thus limiting the ability to implement the Fund’s strategies. Options are also particularly subject to leverage risk and can be subject to liquidity risk.

Leverage Risk

To the extent that a Fund borrows money in the limited circumstances described above under “Non-Principal Investment Strategies” above, it may be leveraged. Leveraging generally exaggerates the effect on NAV of any increase or decrease in the market value of a Fund’s portfolio securities. Borrowings create interest expenses and other expenses (e.g., commitment fees) for a Fund that affect the Fund’s performance. Interest expenses are excluded from the Fund expenses borne by the Adviser under the unitary management fee.

Repurchase Agreements Risk

Repurchase agreements are agreements pursuant to which the Fund acquires securities from a third party with the understanding that the seller will repurchase them at a fixed price on an agreed date. Repurchase agreements may be characterized as loans secured by the underlying securities. If the seller of securities under a repurchase agreement defaults on its obligation to repurchase the underlying securities, as a result of its bankruptcy or otherwise, the Fund will seek to dispose of such securities, which action could involve costs or delays. If the seller becomes insolvent and subject to liquidation or reorganization under applicable bankruptcy or other laws, the Fund’s ability to dispose of the underlying securities may be restricted. If the seller fails to repurchase the securities, the Fund may suffer a loss to the extent proceeds from the sale of the underlying securities are less than the repurchase prices.

Convertible Securities Risk

A convertible security generally is a preferred stock that may be converted within a specified period of time into common stock. Convertible securities nevertheless remain subject to the risks of both debt securities and equity securities. As with other equity securities, the value of a convertible security tends to increase as the price of the underlying stock goes up, and to decrease as the price of the underlying stock goes down. Declining common stock values therefore also may cause the value of the Fund’s

126

investments to decline. Like a debt security, a convertible security provides a fixed income stream and also tends to decrease in value when interest rates rise. Moreover, many convertible securities have credit ratings that are below investment grade and are subject to the same risks as lower-rated debt securities.

Structured Notes Risk

Investments in structured notes involve risks including interest rate risk, credit risk and market risk. Depending on the factors used, changes in interest rates and movement of such factors may cause significant price fluctuations. Structured notes may be less liquid than other types of securities and more volatile than the reference factor underlying the note. This means that the Fund may lose money if the issuer of the note defaults, as the Fund may not be able to readily close out its investment in such notes without incurring losses.

Tax-Advantaged Structure of ETFs

Unlike interests in conventional mutual funds, which typically are bought and sold only at closing NAVs, the Shares are traded throughout the day in the secondary market on a national securities exchange, and are created and redeemed in-kind and/or for cash in Creation Units at each day’s next calculated NAV. To the extent Creation Units are created and redeemed in-kind, those arrangements are designed to protect shareholders from the adverse effects on a Fund’s portfolio that could arise from frequent cash redemption transactions. In a conventional mutual fund, redemptions can have an adverse tax impact on taxable shareholders because the mutual funds may need to sell portfolio securities to obtain cash to meet fund redemptions. These sales may generate taxable gains that must be distributed to the shareholders of the mutual fund, whereas to the extent Creation Units are redeemed in-kind, the Shares’ in-kind redemption mechanism generally will not lead to such taxable events for a Fund or its shareholders.

Each Fund may recognize gains as a result of rebalancing its securities holdings to reflect changes in the Fund’s Underlying Index. Each Fund also may be required to distribute any such gains to its shareholders to avoid adverse federal income tax consequences. For information concerning the tax consequences of distributions, see the section entitled “Dividends, Other Distributions and Taxes” in this Prospectus.

Portfolio Holdings

A description of the Trust’s policies and procedures with respect to the disclosure of the Funds’ portfolio holdings is available in the Trust’s SAI, which is available at www.powershares.com.

Management of the Funds

Invesco PowerShares Capital Management LLC is a registered investment adviser with its offices at 3500 Lacey Road, Suite 700, Downers Grove, Illinois 60515. The Adviser serves as the investment adviser to the Trust, PowerShares Exchange-Traded Fund Trust, PowerShares Exchange-Traded Fund Trust II, PowerShares India Exchange-Traded Fund Trust, PowerShares Actively Managed Exchange-Traded Fund Trust, and PowerShares Actively Managed Exchange-Traded Commodity Fund Trust, a family of ETFs with combined assets under management of approximately $[                ] billion as of [     ].

128

[Out of the unitary Management Fee, the Adviser pays substantially all expenses of each Fund, including the cost of transfer agency, custody, fund administration, legal, audit and other services, except for advisory fees, distribution fees, if any, brokerage expenses, taxes, Acquired Fund Fees and Expenses, if any, interest, litigation expenses and other extraordinary expenses.]

Each Fund may invest in money market funds that are managed by affiliates of the Adviser. The indirect portion of the management fee that a Fund incurs through such investments is in addition to the Adviser’s unitary management fee. Therefore, the Adviser has agreed to waive the management fees that it receives in an amount equal to the indirect management fees that a Fund incurs through its investments in affiliated money market funds through [     ]. There is no guarantee that the Adviser will extend the waiver of the fees past that date.

A discussion regarding the basis for the Board’s approval of the Trust’s investment advisory agreements with respect to each Fund will be available in the Trust’s [Annual Report to shareholders for the fiscal year ending             .]

How to Buy and Sell Shares

Each Fund issues or redeems its Shares at NAV per Share only in Creation Units or Creation Unit Aggregations.

Most investors will buy and sell Shares of each Fund in secondary market transactions through brokers. Shares of each Fund are listed for trading on the secondary market on the Exchange. Shares can be bought and sold throughout the trading day like other publicly traded shares. There is no minimum investment. Although Shares generally are purchased and sold in “round lots” of 100 Shares, brokerage firms typically permit investors to purchase or sell Shares in smaller “odd lots,” at no per share price differential. When buying or selling Shares through a broker, you will incur customary brokerage commissions and charges, and you may pay some or all of the spread between the bid and the offered price in the secondary market on each leg of a round trip (purchase and sale) transaction. The Shares of the Funds trade on the Exchange under the following symbols:

Share prices are reported in dollars and cents per Share.

129

APs may acquire Shares directly from a Fund, and APs may tender their Shares for redemption directly to a Fund, at NAV per Share only in Creation Units or Creation Unit Aggregations, and in accordance with the procedures described in the SAI.

Under normal circumstances, a Fund will pay out redemption proceeds to a redeeming AP within two days after the AP’s redemption request is received, in accordance with the process set forth in the Fund’s SAI and in the agreement between the AP and the Fund’s distributor. However, a Fund reserves the right, including under stressed market conditions, to take up to seven days after the receipt of a redemption request (as discussed above) to pay an AP, all as permitted by the 1940 Act. A Fund anticipates regularly meeting redemption requests primarily through in-kind redemptions. However, each Fund reserves the right to pay redemption proceeds to an AP in cash, consistent with the Trust’s exemptive relief. In particular, as the planned termination date of a Fund approaches, the Fund may elect to accept redemption orders mostly or entirely in cash. As bonds held by a Fund begin to mature, redemptions may be effected increasingly in cash. Cash used for redemptions will be raised from the sale of portfolio assets or may come from existing holdings of cash or cash equivalents.

Each Fund may liquidate and terminate at any time without shareholder approval.

Book Entry

Shares are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding Shares and is recognized as the owner of all Shares for all purposes.

Investors owning Shares are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for all Shares. Participants in DTC include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of Shares, you are not entitled to receive physical delivery of stock certificates or to have Shares registered in your name, and you are not considered a registered owner of Shares. Therefore, to exercise any right as an owner of Shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book entry or “street name” form.

Share Trading Prices

The trading prices of a Fund’s shares listed on the Exchange may differ from the Fund’s daily NAV. Market forces of supply and demand, economic conditions and other factors may affect the trading prices of Shares.

The approximate value of Shares of each Fund, an amount representing on a per share basis the sum of the current market price of the securities accepted by the Fund in exchange for Shares of the Fund and an estimated cash component will be disseminated every 15 seconds throughout the trading day through the facilities of the Consolidated Tape Association. This approximate value should not be viewed as a “real-time” update of the NAV per Share of a Fund because the approximate value will not be calculated in the same manner as the NAV, which is computed once a day, generally at the end of the business day. The Funds are not involved in, or responsible for, the calculation or dissemination of the approximate value of the Shares, and the Funds do not make any warranty as to the accuracy of the approximate value.

Frequent Purchases and Redemptions of Shares

Shares of the Funds may be purchased and redeemed directly from the Funds only in Creation Units by APs. The vast majority of trading in Shares of the Funds occurs on the secondary market and does not involve a Fund directly. In-kind purchases and redemptions of Creation Units by APs and cash trades on the secondary market are unlikely to cause many of the harmful effects of frequent purchases or redemptions of Shares of a Fund. Cash purchases or redemptions of Creation Units, however, can result in increased tracking error, disruption of portfolio management, dilution to the Funds and increased transaction costs, which could negatively impact the Funds’ ability to achieve their investment objectives,

130

and may lead to the realization of capital gains. These consequences may increase as the frequency of cash purchases and redemptions of Creation Units by APs increases. However, direct trading by APs is critical to ensuring that Shares trade at or close to NAV.

To minimize these potential consequences of frequent purchases and redemptions of Shares, a Fund imposes transaction fees on purchases and redemptions of Creation Units to cover the custodial and other costs the Funds incur in effecting trades. In addition, the Adviser monitors trades by APs for patterns of abusive trading, and the Funds reserve the right to not accept orders from APs that the Adviser has determined may be disruptive to the management of the Funds or otherwise are not in the best interests of the Funds. For these reasons, the Board has not adopted policies and procedures with respect to frequent purchases and redemptions of Shares of the Funds.

Dividends, Other Distributions and Taxes

Dividends and Other Distributions

Ordinarily, dividends from net investment income, if any, are declared and paid monthly by each Fund. Each Fund also intends to distribute its net realized capital gains, if any, to shareholders annually. Dividends and other distributions may be declared and paid more frequently to comply with the distribution requirements of Subchapter M of the Internal Revenue Code of 1986, as amended, and to avoid a federal excise tax imposed on regulated investment companies.

Distributions in cash may be reinvested automatically in additional whole Shares only if the broker through whom you purchased Shares makes such option available.

Taxes

As with any investment, you should consider how your investment in Shares will be taxed. The tax information in this Prospectus is provided as general information. You should consult your own tax professional about the tax consequences of an investment in Shares.

Unless your investment in Shares is made through a tax-exempt entity or tax-deferred retirement account, such as an individual retirement account, you need to be aware of the possible tax consequences when:

Taxes on Distributions

As stated above, dividends from net investment income, if any, ordinarily are declared and paid monthly. Each Fund also may pay a special distribution at the end of a calendar year to comply with federal tax requirements and/or to minimize or eliminate federal tax liability. In general, your distributions are subject to federal income tax when they are paid, whether you take them in cash or Shares (if reinvestment is available from the broker through whom you purchased your Shares).

Dividends paid to you out of a Fund’s net investment income and net realized short-term capital gains, if any, are taxable as ordinary income. Although (1) a Fund’s dividends attributable to its “qualified dividend income” generally will be subject to federal income tax for individual and certain other non-corporate shareholders (each, an “individual shareholder”) who satisfy certain restrictions with respect to their Shares at the lower maximum rates for long-term capital gains described in the next paragraph and (2) a portion of a Fund’s dividends also may be eligible for the dividends-received deduction allowed to corporations, each Fund does not expect to distribute a significant amount of dividends eligible for those lower rates or deduction.

Distributions to you of net long-term capital gains, if any, in excess of net short-term capital losses are taxable as long-term capital gains, regardless of how long you have held the Shares. Those gains of individual shareholders generally are subject to federal income tax at the maximum rates of 15% (20% for certain high income taxpayers).

131

Distributions to you in excess of a Fund’s current and accumulated earnings and profits, if any, are treated as a tax-free return of capital to the extent of your basis in your Shares and as capital gain thereafter. A distribution will reduce a Fund’s NAV per Share and may be taxable to you (as ordinary income or long-term capital gain) even though, from an investment standpoint, the distribution constitutes a partial return of capital.

By law, a Fund is required to withhold 28% of distributions otherwise payable to you if you are an individual shareholder and have not provided a correct social security number or other taxpayer identification number or otherwise are subject to backup withholding.

There is a risk that the tax treatment of futures, options, and options on futures may be affected by future regulatory or legislative changes that could affect the character, timing, and/or amount of a Fund’s taxable income or gains and distributions.

Taxes on Share Sales

Any capital gain or loss you realize upon a sale of Shares generally is treated as long-term capital gain or loss if you held the Shares for more than one year and as short-term capital gain or loss if you held the Shares for one year or less. Your ability to deduct capital losses realized on a sale of Shares may be limited.

Taxes on Purchase and Redemption of Creation Units

An AP that exchanges securities for a Creation Unit generally will recognize a capital gain or loss equal to the difference between the market value of the Creation Unit and the sum of the AP’s aggregate basis in the securities surrendered plus any cash component paid. An AP that redeems a Creation Unit in exchange for securities generally will recognize a capital gain or loss equal to the difference between the AP’s basis in the Creation Unit and the aggregate market value of the securities received plus or minus an amount, if any, equal to the difference between the NAV of the redeemed Shares, as next determined after receipt of a request in proper form, and the value of those securities. The Internal Revenue Service, however, may assert that a loss realized upon an exchange of securities for a Creation Unit, or of a Creation Unit for securities, cannot be deducted currently under the rules governing “wash sales,” or on the ground that there has been no significant change in the AP’s economic position. An AP exchanging securities should consult its own tax advisor(s) with respect to whether wash sale rules apply and when a loss otherwise might not be deductible.

Any capital gain or loss realized upon redemption of a Creation Unit generally is treated as long-term capital gain or loss if the Shares have been held for more than one year and as short-term capital gain or loss if the Shares have been held for one year or less.

If you purchase or redeem one or more Creation Units, you will be sent a confirmation statement showing how many Shares you purchased or sold and at the price thereof.

Foreign Income Taxes

Certain foreign governments levy withholding or other taxes on dividend and interest income. A Fund also may be subject to foreign income taxes with respect to other income. Although in some countries a portion of these taxes may be recoverable, the non-recovered portion of foreign withholding taxes will reduce the income received from investments in such countries.

A Fund may elect to pass its credits for foreign income taxes, subject to certain limitations, through to its shareholders for a taxable year if more than 50% of its assets at the close of the year, by value, consists of stock and securities of foreign corporations. If a Fund makes this election, each shareholder will be treated as having paid a proportionate share of the Fund’s foreign income taxes, but the shareholder must include an equal amount in gross income.

The foregoing discussion summarizes some of the more important possible consequences under current federal, state and local tax law of an investment in the Funds. It is not a substitute for personal tax advice. You also may be subject to state, local, and/or foreign tax on a Fund’s distributions and sales and/or redemptions of Shares. Consult your personal tax advisor(s) about the potential tax consequences of an investment in the Shares under all applicable tax laws.

132

Distributor

Invesco Distributors, Inc. (the “Distributor”) serves as the distributor of Creation Units for each Fund on an agency basis. The Distributor does not maintain a secondary market in Shares. The Distributor is an affiliate of the Adviser.

Net Asset Value

The Bank of New York Mellon (“BNYM”) calculates each Fund’s NAV at the close of regular trading (normally 4:00 p.m., Eastern time) every day the New York Stock Exchange (“NYSE”) is open, provided that U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments on any day that the Securities Industry and Financial Markets Association announces an early closing time. The NAV for each Fund will be calculated and disseminated on each day that the NYSE is open. NAV is calculated by deducting all of a Fund’s liabilities from the total value of its assets and dividing the result by the number of Shares outstanding, rounding to the nearest cent. Generally, the portfolio securities are recorded in the NAV no later than trade date plus one day. All valuations are subject to review by the Board or its delegate.

In determining NAV, expenses are accrued and applied daily and securities and other assets for which market quotations are readily available are valued at market value. Securities listed or traded on an exchange generally are valued at the last sales price or official closing price that day as of the close of the exchange where the security is primarily traded. Investment companies are valued using such company’s NAV per share, unless the shares are exchange-traded, in which case they will be valued at the last sale or official closing price on the exchanges on which they primarily trade. Deposits, other obligations of U.S. and non-U.S. banks and financial institutions, and cash equivalents are valued at their daily account value. Options generally are valued at the closing price (and, if no closing price is available, at the mean of the last bid/ask quotations), generally from the exchange where such instruments principally trade. Futures contracts generally are valued based on quotations from a pricing vendor or market makers. Swaps generally are valued using pricing provided from independent pricing services.

Certain securities may not be listed on an exchange; typically, those securities are bought and sold by institutional investors in individually negotiated private transactions. Such securities, as well as listed securities whose market price is not readily available, will be valued using pricing provided from independent pricing services or by another method that the Adviser, in its judgment, believes will better reflect the security’s fair value in accordance with the Trust’s valuation policies and procedures approved by the Board.

Even when market quotations are available for portfolio securities, they may be stale or unreliable because the security is not traded frequently, trading on the security ceased before the close of the trading market or issuer specific events occurred after the security ceased trading or because of the passage of time between the close of the market on which the security trades and the close of the NYSE and when a Fund calculates its NAV. Events that may cause the last market quotation to be unreliable include a merger or insolvency, events which affect a geographical area or an industry segment, such as political events or natural disasters, or market events, such as a significant movement in the U.S. market. Where market quotations are not readily available, including where the Adviser determines that the closing price of the security is unreliable, the Adviser will value the security at fair value in good faith using procedures approved by the Board. Fair value pricing involves subjective judgments and it is possible that a fair value determination for a security is materially different than the value that could be realized upon the sale of the security. In addition, fair value pricing could result in a difference between the prices used to calculate a Fund’s NAV and the prices used by the Fund’s Underlying Index. This may adversely affect a Fund’s ability to track its Underlying Index. With respect to securities that primarily are listed on foreign exchanges, the value of a Fund’s portfolio securities may change on days when you will not be able to purchase or sell your Shares.

Premium/Discount Information

Information on the daily NAV per Share for each Fund, once available, will be found at www.powershares.com.

Other Information

Section 12(d)(1) of the 1940 Act restricts investments by investment companies (and companies relying on Section 3(c)(1) or 3(c)(7) of the 1940 Act) in the securities of other investment companies. However, registered investment companies are permitted to invest in a Fund beyond the limits set forth in Section 12(d)(1) subject to certain terms and conditions set forth in an SEC exemptive order issued to the Trust, including that such investment companies enter into an agreement with the Trust on behalf of the Fund prior to exceeding the limits imposed by Section 12(d)(1). Additionally, a Fund is permitted to invest in other registered investment companies beyond the limits set forth in Section 12(d)(1) subject to certain terms and conditions set forth in another exemptive order that the SEC has issued to the Trust. If a Fund relies on this exemptive relief, however, other investment companies may not invest in the Fund beyond the statutory provisions of Section 12(d)(1).

135

Continuous Offering

The method by which Creation Unit Aggregations of Shares are created and traded may raise certain issues under applicable securities laws. Because new Creation Unit Aggregations of Shares are issued and sold by a Fund on an ongoing basis, a “distribution,” as such term is used in the Securities Act of 1933, as amended (the “Securities Act”), may occur at any point. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the prospectus delivery requirement and liability provisions of the Securities Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Unit Aggregations after placing an order with the Distributor, breaks them down into constituent Shares and sells such Shares directly to customers, or if it chooses to couple the creation of a supply of new Shares with an active selling effort involving solicitation of secondary market demand for Shares. A determination of whether one is an underwriter for purposes of the Securities Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to a characterization as an underwriter.

Broker-dealer firms also should note that dealers who are not “underwriters” but are effecting transactions in Shares, whether or not participating in the distribution of Shares, generally are required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(a)(3)(C) of the Securities Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. As a result, broker-dealer firms should note that dealers who are not “underwriters” but are participating in a distribution (as contrasted with engaging in ordinary secondary market transactions), and thus dealing with the Shares that are part of an overallotment within the meaning of Section 4(a)(3)(C) of the Securities Act, will be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the Securities Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the Securities Act only is available with respect to transactions on a national exchange.

Delivery of Shareholder Documents—Householding

Householding is an option available to certain investors of the Funds. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Householding for the Funds is available through certain broker-dealers. If you are interested in enrolling in householding and receiving a single copy of the Prospectus and other shareholder documents, please contact your broker-dealer. If you currently are enrolled in householding and wish to change your householding status, please contact your broker-dealer.

TABLE OF CONTENTS

2

GENERAL DESCRIPTION OF THE TRUST AND THE FUND

The Trust was organized as a Delaware statutory trust on October 13, 2015 and is authorized to have multiple series or portfolios. The Trust is an open-end management investment company, registered under the Investment Company Act of 1940, as amended (the “1940 Act”). The Trust currently consists of [21] funds. This SAI relates to 18 series of the Trust: PowerShares BulletShares 2018 Corporate Bond Portfolio, PowerShares BulletShares 2019 Corporate Bond Portfolio, PowerShares BulletShares 2020 Corporate Bond Portfolio, PowerShares BulletShares 2021 Corporate Bond Portfolio, PowerShares BulletShares 2022 Corporate Bond Portfolio, PowerShares BulletShares 2023 Corporate Bond Portfolio, PowerShares BulletShares 2024 Corporate Bond Portfolio, PowerShares BulletShares 2025 Corporate Bond Portfolio, PowerShares BulletShares 2026 Corporate Bond Portfolio and PowerShares BulletShares 2027 Corporate Bond Portfolio (collectively, the “Investment Grade Corporate Bond Funds”), PowerShares BulletShares 2018 High Yield Corporate Bond Portfolio, PowerShares BulletShares 2019 High Yield Corporate Bond Portfolio, PowerShares BulletShares 2020 High Yield Corporate Bond Portfolio, PowerShares BulletShares 2021 High Yield Corporate Bond Portfolio, PowerShares BulletShares 2022 High Yield Corporate Bond Portfolio, PowerShares BulletShares 2023 High Yield Corporate Bond Portfolio, PowerShares BulletShares 2024 High Yield Corporate Bond Portfolio and PowerShares BulletShares 2025 High Yield Corporate Bond Portfolio (collectively, the High Yield Corporate Bond Funds”) (each, a “Fund” and collectively, the “Funds”). Each Fund is based on an underlying index (each, an “Underlying Index” and collectively, the “Underlying Indices”) of corporate bonds. Each Fund is “non-diversified,” and as such, the Fund’s investments are not required to meet certain diversification requirements under the 1940 Act. The shares of the Funds are referred to in this SAI as “Shares.”

The investment objective of each Fund Portfolio is to seek investment results that correspond generally to the performance, before fees and expenses, of its respective Underlying Index.

Each Fund’s investment objective is non-fundamental and may be changed without the consent of the holders of a majority of each Fund’s outstanding shares. Additional information concerning each Fund’s investment objective and principal investment strategies is contained in that Fund’s Prospectus.

Invesco PowerShares Capital Management LLC (the “Adviser”), an indirect, wholly-owned subsidiary of Invesco Ltd., manages the Funds.

Each Investment Grade Corporate Bond Fund issues and redeems Shares at net asset value (“NAV”) only in aggregations of 150,000 Shares (each a “Creation Unit” or a “Creation Unit Aggregation”), and each High Yield Corporate Bond Fund issues and redeems Shares at NAV in aggregations of 100,000 Shares. Each Fund generally issues and redeems Creation Units principally in exchange for a basket of component securities included in its Underlying Index (the “Deposit Securities”), and./or an amount of cash in lieu of some or all of the Deposit Securities, together with the deposit of a specified cash payment (the “Cash Component”), plus certain transaction fees. However, each Fund also reserves the right to permit or require Creation Units to be issued in exchange for cash. As the planned termination date of a Fund approaches, the Fund may elect to accept creation and redemption orders mostly or entirely in cash. As bonds held by a Fund begin to mature, creations and redemptions may be effected increasingly in cash.

Each Fund is expected to be approved for listing, subject to notice of issuance, on NYSE Arca, Inc. (the “Exchange”). Shares will trade throughout the day on the Exchange at market prices that may be below, at, or above NAV. In the event of the liquidation of a Fund, the Trust may decrease the number of Shares in a Creation Unit.

Each Fund may issue Shares in advance of receipt of Deposit Securities subject to various conditions, including a requirement to maintain on deposit with the Trust cash at least equal to 105% of the market value of the missing Deposit Securities. See the “Creation and Redemption of Creation Unit Aggregations” section. To offset the added brokerage and other transaction costs a Fund incurs with using cash to purchase the requisite Deposit Securities, during each instance of cash creations or redemptions, the Funds may impose transaction fees that will be higher than the transaction fees associated with in-kind creations or redemptions. For more information, see the section below titled “Creation and Redemption of Creation Unit Aggregations.”

EXCHANGE LISTING AND TRADING

There can be no assurance that a Fund, once listed, will continue to meet the requirements of the Exchange necessary to maintain the listing of its Shares. The Exchange may, but is not required to, remove the Shares from listing if: (i) following the initial 12-month period beginning at the commencement of trading of a Fund, there are fewer than 50 beneficial owners of the Shares; (ii) the value of a Fund’s Underlying Index no longer is calculated or available (iii) the “intraday indicative value” (“IIV”) of the Fund is no longer calculated or available; or (iv) such other event shall occur or condition shall exist that, in the opinion of the Exchange, makes further dealings on such Exchange inadvisable. The Exchange will remove the Shares from listing and trading upon termination of a Fund.

As in the case of other stocks traded on the Exchange, brokers’ commissions on transactions will be based on negotiated commission rates at customary levels.

The Trust reserves the right to adjust the price levels of the Shares in the future to help maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of a Fund.

In order to provide additional information regarding the indicative value of Shares of the Funds, the Exchange or a market data vendor will disseminate every 15 seconds through the facilities of the Consolidated Tape Association or other widely disseminated means, an updated “intraday indicative value” (“IIV”) for a Fund, as calculated by an information provider or market data vendor. The Trust is not involved in, or responsible for any aspect of, the calculation or dissemination of the IIVs and makes no representation or warranty as to the accuracy of the IIVs.

Shares of the Funds are not sponsored, endorsed, or promoted by the Exchange. The Exchange makes no representation or warranty, express or implied, to the owners of Shares of the Funds or any member of the public regarding the ability of a Fund to track the total return performance of an Underlying Index or the ability of an Underlying Index to track stock market performance. The Exchange is not responsible for, nor has it participated in, the determination of the compilation or the calculation of an Underlying Index, nor in the determination of the timing of, prices of, or quantities of Shares of the Funds to be issued, nor in the determination or calculation of the equation by which the shares are redeemable. The Exchange has no obligation or liability to owners of the Shares of the Funds in connection with the administration, marketing, or trading of the Shares of the Funds.

The Exchange does not guarantee the accuracy and/or the completeness of an Underlying Index or the data included therein. The Exchange makes no warranty, express or implied, as to results to be obtained by the Trust on behalf of the Funds, owners of the Shares, or any other person or entity from the use of an Underlying Index or the data included therein. The Exchange makes no express or implied warranties, and hereby expressly disclaims all warranties of merchantability or fitness for a particular purpose with respect to an Underlying Index or the data included therein. Without limiting any of the foregoing, in no event shall the Exchange have any liability for any lost profits or indirect, punitive, special, or consequential damages even if notified of the possibility thereof.

INVESTMENT RESTRICTIONS

Each Fund has adopted as fundamental policies the investment restrictions numbered (1) through (7) below. Except as otherwise noted below, each Fund, as a fundamental policy, may not:

(1) Invest more than 25% of the value of its total assets in securities of issuers in any one industry or group of industries, except to the extent that the Underlying Index concentrates in an industry or group of industries. This restriction does not apply to obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities.

(2) Borrow money, except the Fund may borrow money to the extent permitted by (i) the 1940 Act, (ii) the rules and regulations promulgated by the Securities and Exchange Commission (“SEC”) under the 1940 Act, or (iii) an exemption or other relief applicable to the Fund from the provisions of the 1940 Act.

4

(3) Act as an underwriter of another issuer’s securities, except to the extent that the Fund may be deemed to be an underwriter within the meaning of the Securities Act of 1933, as amended (the “Securities Act”) in connection with the purchase and sale of portfolio securities.

(4) Make loans to other persons, except through (i) the purchase of debt securities permissible under the Fund’s investment policies, (ii) repurchase agreements or (iii) the lending of portfolio securities, provided that no such repurchase agreements or loan of portfolio securities may be made by the Fund if, as a result, the aggregate of such repurchase agreements and loans would exceed 33  ¹ / ₃ % of the value of the Fund’s total assets.

(5) Purchase or sell physical commodities unless acquired as a result of ownership of securities or other instruments (but this shall not prevent the Fund (i) from purchasing or selling options, futures contracts or other derivative instruments, or (ii) from investing in securities or other instruments backed by physical commodities).

(6) Purchase or sell real estate unless acquired as a result of ownership of securities or other instruments (but this shall not prohibit the Fund from purchasing or selling securities or other instruments backed by real estate or of issuers engaged in real estate activities).

(7) Issue senior securities, except as permitted under the 1940 Act.

Except for restrictions (2), (4)(ii) and (iii), and (7), if a Fund adheres to a percentage restriction at the time of investment, a later increase in percentage resulting from a change in market value of the investment or the total assets, or the sale of a security out of its portfolio, will not constitute a violation of that restriction. With respect to restrictions (2), (4)(ii) and (iii), and (7), in the event that a Fund’s borrowings, repurchase agreements and loans of portfolio securities at any time exceed 33  ¹ / ₃ % of the value of the Fund’s total assets (including the amount borrowed and the collateral received) less the Fund’s liabilities (other than borrowings or loans) due to subsequent changes in the value of the Fund’s assets or otherwise, within three days (excluding Sundays and holidays), the Fund will take corrective action to reduce the amount of its borrowings, repurchase agreements and loans of portfolio securities to an extent that such borrowings, repurchase agreements and loans will not exceed 33  ¹ / ₃ % of the value of the Fund’s total assets (including the amount borrowed and the collateral received) less the Fund’s liabilities (other than borrowings or loans).

The foregoing fundamental investment policies cannot be changed as to a Fund without approval by holders of a “majority of the Fund’s outstanding voting securities.” As defined in the 1940 Act, this means the vote of (i) 67% or more of the Fund’s Shares present at a meeting, if the holders of more than 50% of the Fund’s Shares are present or represented by proxy, or (ii) more than 50% of the Fund’s Shares, whichever is less.

In addition to the foregoing fundamental investment policies, each Fund also is subject to the following non-fundamental investment restrictions and policies, which may be changed by the Board of Trustees of the Trust (the “Board”) without shareholder approval. The Fund may not:

(1) Sell securities short, unless the Fund owns or has the right to obtain securities equivalent in kind and amount to the securities sold short at no added cost, and provided that transactions in options, futures contracts, options on futures contracts or other derivative instruments are not deemed to constitute selling securities short.

(2) Purchase securities on margin, except that the Fund may obtain such short-term credits as are necessary for the clearance of transactions; and provided that margin deposits in connection with futures contracts, options on futures contracts or other derivative instruments shall not constitute purchasing securities on margin.

[(3) Purchase securities of open-end or closed-end investment companies except in compliance with the 1940 Act, although the Fund may not acquire any securities of registered open-end investment companies or registered unit investment trusts in reliance on Sections 12(d)(1)(F) and 12(d)(1)(G) of the 1940 Act if the Fund has knowledge that its Shares are purchased by another investment company investor in reliance on the provisions of Sections 12(d)(1)(F) or 12(d)(1)(G).]

(4) Invest in direct interests in oil, gas or other mineral exploration programs or leases; however, the Fund may invest in the securities of issuers that engage in these activities.

5

(5) Invest in illiquid securities if, as a result of such investment, more than 15% of the Fund’s net assets would be invested in illiquid securities.

Each Fund’s investment objective is a non-fundamental policy that the Board may change without approval by shareholders upon 60 days’ written notice to shareholders.

In accordance with the 1940 Act, each Fund has adopted a non-fundamental policy to invest in securities suggested by such Fund’s name (each, an “80% investment policy”). Each Fund with such a policy considers securities suggested by its name to be those securities that comprise its Underlying Index. Each such Fund will meet its 80% investment policy by investing at least 80% of its net assets (plus the amount of any borrowing for investment purposes) in such securities. Each such Fund will provide its shareholders with at least 60 days’ prior written notice of any change to its 80% investment policy.

INVESTMENT STRATEGIES AND RISKS

Investment Strategies

The investment objective of each Fund is to seek investment results that correspond generally to the performance, before fees and expenses, of its respective Underlying Index. Each Fund seeks to achieve its investment objective by investing primarily in securities that comprise its Underlying Index. Each Fund operates as an index fund and will not be actively managed.

Each Fund generally uses a “sampling” methodology to seek to achieve its respective investment objective. A Fund using a sampling methodology may not be as well-correlated with the return of its Underlying Index as would be the case if the Fund purchased all of the securities in its Underlying Index in the proportions represented in the Underlying Index.

Investment Risks

A discussion of the principal risks associated with an investment in the Funds is contained in the Funds’ Prospectus in the “Summary Information—Principal Risks of Investing in the Fund,” “Additional Information About the Funds’ Strategies and Risks—Principal Risks of Investing in the Funds” and “—Additional Risks of Investing in the Funds” sections. The discussion below supplements, and should be read in conjunction with, these sections.

An investment in a Fund should be made with an understanding that the value of the Fund’s portfolio holdings may fluctuate in accordance with changes in the financial condition of an issuer of the portfolio securities, the value of securities in general and other factors that affect the market.

An investment in a Fund also should be made with an understanding of the risks inherent in an investment in securities, including the risk that the financial condition of the issuers may become impaired or that the general condition of the securities market may deteriorate (either of which may cause a decrease in the value of the portfolio holdings and thus in the value of Shares). Securities are susceptible to general securities market fluctuations and to volatile increases and decreases in value as market confidence and perceptions of the companies issuing the securities change. These investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies, inflation and interest rates, economic expansion or contraction, and global or regional political, economic or banking crises.

The Funds are not actively managed, and therefore the adverse financial condition of any one issuer will not result in the elimination of its securities from a Fund’s portfolio unless the respective index provider removes the securities from such Fund’s Underlying Index.

General Risk Factors . The NAV of a Fund is expected to fluctuate, reflecting fluctuations in the market value of its portfolio positions. The value of fixed-income instruments held by a Fund, if applicable, generally fluctuates inversely with interest rate movements. In other words, bond prices generally fall as interest rates rise and generally rise as interest rates fall. Longer term bonds held by a Fund, if applicable, are subject to greater interest rate risk.

6

Bonds. Each Fund invests in U.S. registered, dollar-denominated bonds. A bond is an interest-bearing security issued by a company, governmental unit or, in some cases, a non-U.S. entity. The issuer of a bond has a contractual obligation to pay interest at a stated rate on specific dates and to repay principal (the bond’s face value) periodically or on a specified maturity date. An issuer may have the right to redeem or “call” a bond before maturity, in which case the investor may have to reinvest the proceeds at lower market rates. Most bonds bear interest income at a “coupon” rate that is fixed for the life of the bond. The value of a fixed rate bond usually rises when market interest rates fall, and falls when market interest rates rise. Accordingly, a fixed rate bond’s yield (income as a percent of the bond’s current value) may differ from its coupon rate as its value rises or falls. Other types of bonds bear income at an interest rate that is adjusted periodically. Because of their adjustable interest rates, the value of “floating-rate” or “variable-rate” bonds fluctuates much less in response to market interest rate movements than the value of fixed rate bonds. A Fund may treat some of these bonds as having a shorter maturity for purposes of calculating the weighted average maturity of its investment portfolio. Bonds may be senior or subordinated obligations. Senior obligations generally have the first claim on a corporation’s earnings and assets and, in the event of liquidation, are paid before subordinated obligations. Bonds may be unsecured (backed only by the issuer’s general creditworthiness) or secured (also backed by specified collateral).

Borrowing . Certain Funds have established a line of credit with certain banks from which they may borrow funds for temporary or emergency purposes. To the extent the Funds effect cash redemptions or partial cash redemptions, the Funds may use lines of credit to meet large or unexpected redemptions that would otherwise force the Funds to liquidate securities under circumstances which are unfavorable to the Funds’ remaining shareholders. The Funds may be required to pay fees to the banks to maintain the lines of credit, which increases the cost of borrowing over the stated interest rate.

Corporate Bonds . Each Fund invests in corporate bonds. The investment return of corporate bonds reflects interest on the security and changes in the market value of the security. The market value of a corporate bond may be affected by the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the market place. There is a risk that the issuers of the securities may not be able to meet their obligations on interest or principal payments at the time called for by an instrument.

Cyber Security and Operational Risk . With the increased use of technologies in the course of business, the Funds and their service providers have become potentially more susceptible to operational, information security and risks resulting from cyber-attacks. Cyber-attacks are intentional actions and unintentional events that may cause operational disruptions and failures, including the theft or corruption of data maintained online or digitally, denial of service on websites, and the unauthorized release of confidential information. Successful cyber-attacks against, or cyber security breakdowns of, a Fund and/or third party service providers may adversely impact the Funds and their shareholders by, among other things, interfering with the processing of shareholder transactions, impacting a Fund’s ability to calculate its net asset value, causing the release of private shareholder information or confidential Fund information, impeding trading, causing reputational damage, and subjecting a Fund to regulatory fines, penalties or financial losses, reimbursement or other compensation costs, and additional compliance and cyber security risk management costs. Although the Funds and their service providers may have established business continuity plans and systems designed to reduce the risks or adverse effects associated with cyber-attacks, there are inherent limitations in these plans and systems, including that certain risks may not have been identified, in large part because different or unknown threats may emerge in the future. Similar types of cyber security risks also are present for issuers of securities in which a Fund invests, which could result in material adverse consequences for such issuers, and may cause the Fund’s investment in such securities to lose value.

A Fund’s investments or its service providers may be negatively impacted due to operational risks arising from factors such as processing errors and human errors, inadequate or failed internal or external processes, failures in systems and technology, changes in personnel, and errors caused by third-party service providers or trading counterparties. In particular, these errors or failures as well as other technological issues may adversely affect the Funds’ ability to calculate their net asset values in a timely manner, including over a potentially extended period. Although the Funds attempt to minimize such failures through controls and oversight, it is not possible to identify all of the operational risks that may affect a Fund or to develop processes and controls that completely eliminate or mitigate the occurrence of such failures. A Fund and its shareholders could be negatively impacted as a result.

7

Derivatives Regulatory Risk . The laws and regulations that apply to derivatives (e.g., swaps, futures, etc.) and persons who use them (including a Fund, the Adviser and others) are rapidly changing in the U.S. and abroad. As a result, restrictions and additional regulations may be imposed on these parties, trading restrictions may be adopted and additional trading costs are possible. The impact of these changes on any of the Funds and their investment strategies is not yet fully ascertainable.

In particular, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), was signed into law in July 2010. The Dodd-Frank Act is still changing radically the way in which the U.S. financial system is supervised and regulated. Title VII of the Dodd-Frank Act sets forth a new legislative framework for over-the-counter (“OTC”) derivatives, including financial instruments, such as swaps, in which the Funds may invest. Title VII of the Dodd-Frank Act makes broad changes to the OTC derivatives market, grants significant new authority to the SEC and the Commodities Futures Trading Commission (“CFTC”) to regulate OTC derivatives and market participants, and requires clearing and exchange trading of many OTC derivatives transactions. The CFTC and SEC finalized the definition of “swap” and “security-based swap.” These definitions provide the parameters around which contracts will be subject to further regulation under the Dodd-Frank Act.

Provisions in the Dodd-Frank Act also include new capital and margin requirements and the mandatory use of clearinghouse mechanisms for and exchange trading of many OTC derivative transactions. The CFTC, SEC and other federal regulators have been tasked with developing the rules and regulations enacting the provisions of the Dodd-Frank Act. Because there is a prescribed phase-in period during which most of the mandated rulemaking and regulations will be implemented, it is not possible at this time to gauge the exact nature and scope of the impact of the Dodd-Frank Act on any of the Funds. However, swap dealers, major market participants and swap counterparties are experiencing additional regulations, requirements, compliance burdens and associated costs. The new law and the rules may negatively impact a Fund’s ability to meet its investment objective either through limits or requirements imposed on it or upon its counterparties. In particular, new position limits imposed on a Fund or its counterparties may impact that Fund’s ability to invest in futures, options and swaps in a manner that efficiently meets its investment objective. New requirements, even if not directly applicable to the Funds, including capital requirements, changes to the CFTC speculative position limits regime and mandatory clearing, may increase the cost of a Fund’s investments and cost of doing business, which would adversely affect investors.

In December 2015, the SEC proposed a new exemptive rule that would regulate the use of derivatives and other transactions by investment companies registered under the 1940 Act, such as the Funds. The outcome and effect of this proposal cannot be predicted accurately. If the proposed rule is adopted, it could impact the Funds’ ability to invest or remain invested in derivatives and achieve their respective investment objectives. The Adviser continue to evaluate the potential impact of the new governmental regulation on the Funds and may have to make changes to the Funds’ strategies in the future.

Each Fund has filed with the National Futures Association a notice claiming an exclusion from the definition of “commodity pool operator” (“CPO”) under Rule 4.5 under the Commodity Exchange Act, as amended (the “CEA”), with respect to each Fund’s operation. Accordingly, each Fund that has filed such a notice and the Adviser with respect to each such Fund are not subject to registration or regulation as a commodity pool or CPO. Changes to a Fund’s investment strategies or investments may cause the Fund to lose the benefits of the exclusion under Rule 4.5 under the CEA and may trigger additional CFTC regulation. If a Fund becomes subject to CFTC regulation, the Fund may incur additional expenses.

Futures, Options and Other Derivative Transactions .

8

An option on a futures contract gives the purchaser the right, in exchange for a premium, to assume a position in a futures contract at a specified exercise price during the term of the option. Futures contracts are traded on a national futures exchange regulated by the CFTC, which reduces the risk that a Fund will be unable to close out a futures contract. To the extent a Fund uses futures and/or options on futures, it would do so in accordance with Rule 4.5 under the CEA, unless otherwise disclosed.

Each Fund may buy and sell index futures contracts with respect to any index traded on a recognized exchange or board of trade. An index futures contract is an agreement pursuant to which the Fund may agree to take or make a cash payment on an index value. No physical delivery of the securities comprising the index is made. Instead, settlement in cash generally must occur daily and upon the termination of the contract. Generally, index futures contracts are closed out prior to the expiration date of the contract.

When a Fund purchases or sells a futures contract, or sells an option thereon, the Fund is required to “cover” its position in order to limit the risk associated with the use of leverage and other related risks. To cover its position, the Fund may earmark or segregate cash or liquid securities that, when added to any amounts deposited with a futures commission merchant as initial margin, are equal to the market value of the futures contract or otherwise “cover” its position in a manner consistent with the 1940 Act or the rules and SEC interpretations thereunder. If a Fund continues to engage in the described securities trading practices and properly earmarks or segregates assets, the assets will function as a practical limit on the amount of leverage which the Fund may undertake and on the potential increase in the speculative character of the Fund. Such practices are intended to assure the availability of adequate funds to meet the obligations of the Fund arising from such investment activities, although there is no guarantee that they will function as intended.

With respect to futures contracts that are not contractually required to “cash-settle,” a Fund usually must cover its open positions by earmarking or segregating on its records cash or liquid assets equal to the contract’s notional value. For futures contracts that are “cash-settled,” however, a Fund is permitted to earmark or segregate cash or liquid assets in an amount equal to the Fund’s next daily marked-to-market (net) obligation, if any (i.e., a Fund’s daily net liability) rather than the notional value. By earmarking or designating assets equal to only its net obligation under cash-settled futures, a Fund will have the ability to employ leverage to a greater extent than if a Fund were required to earmark or segregate assets equal to the full notional value of such contracts.

Each Fund may also cover its long position in a futures contract by purchasing a put option on the same futures contract with a strike price (i.e., an exercise price) as high or higher than the price of the futures contract. In the alternative, if the strike price of the put is less than the price of the futures contract, a Fund will also earmark or segregate cash or liquid securities equal in value to the difference between the strike price of the put and the price of the futures contract and that can be exercised on any date or that has the same exercise date as the expiration date of the futures contract. Each Fund may also cover its long position in a futures contract by taking a short position in the instruments underlying the futures contract (or, in the case of an index futures contract, a portfolio with a volatility substantially similar to that of the index on which the futures contract is based). Each Fund may cover its short position in a futures contract by taking a long position in the instruments underlying the futures contract.

Each Fund may cover its sale of a call option on a futures contract by taking a long position in the underlying futures contract at a price less than or equal to the strike price of the call option. In the alternative, if the long position in the underlying futures contract is established at a price greater than the strike price of the written (sold) call, a Fund will earmark or segregate cash or liquid securities equal in value to the difference between the strike price of the call and the price of the futures contract. Each Fund may cover its sale of a put option on a futures contract by taking a short position in the underlying futures contract at a price greater than or equal to the strike price of the put option, or, if the short position in the underlying futures contract is established at a price less than the strike price of the written put, a Fund will earmark or segregate cash or liquid securities equal in value to the difference between the strike price of the put and the price of the futures contract.

Eurodollar futures contracts contracts are U.S. dollar-denominated futures contracts that are based on the implied forward London Interbank Offered Rate (“LIBOR”). These contracts enable purchasers to obtain a fixed rate for the lending of funds and sellers to obtain a fixed rate for borrowings. A Fund may use Eurodollar futures contracts and options thereon to hedge against changes in the LIBOR, to which many interest rate swaps and fixed income instruments are linked, or for other purposes.

There are significant risks associated with the Funds’ use of futures contracts and options on futures contracts, including the following: (1) there may be an imperfect or no correlation between the changes in market value of the securities held by a Fund and the prices of futures and options on futures; (2) there may not be a liquid secondary market for a futures contract or option; (3) trading restrictions or limitations may be imposed by an exchange; and (4) government regulations may restrict trading in futures contracts and options on futures. In addition, some strategies reduce a Fund’s exposure to price fluctuations, while others tend to increase its market exposure.

Put and call options on indices are similar to options on securities except that options on an index give the holder the right to receive, upon exercise of the option, an amount of cash if the closing level of the underlying index is greater than (or less than, in the case of puts) the exercise price of the option. This amount of cash is equal to the difference between the closing price of the index and the exercise price of the option, expressed in dollars multiplied by a specified number. Thus, unlike options on individual securities, all settlements are in cash, and gain or loss depends on price movements in the particular market represented by the index generally, rather than the price movements in individual securities. All options written on indices or securities must be covered. If a Fund writes an option on a security, an index or a foreign currency, it will earmark or segregate cash or liquid securities in an amount at least equal to the market value of the option and will maintain the account while the option is open or will otherwise cover the transaction.

The initial purchase (sale) of an option contract is an “opening transaction.” In order to close out an option position prior to expiration, a Fund may enter into a “closing transaction,” which is simply the sale (purchase) of an option contract on the same security with the same exercise price and expiration date as the option contract originally opened. If a Fund is unable to effect a closing purchase transaction with respect to an option it has written, it will not be able to sell the underlying security until the option expires or the Fund delivers the security upon exercise.

Each Fund may purchase and write options on an exchange or over-the-counter. OTC options differ from exchange-traded options in several respects. They are transacted directly with dealers and not with a clearing corporation, and therefore entail the risk of non-performance by the dealer. OTC options are available for a greater variety of securities and for a wider range of expiration dates and exercise prices than are available for exchange-traded options. Because OTC options are not traded on an exchange, pricing is done normally by reference to information from a market maker.

The market value of an option generally reflects the market price of an underlying security. Other principal factors affecting market value include supply and demand, interest rates, the pricing volatility of the underlying security and the time remaining until the expiration date.

Risks associated with options transactions include: (1) there may be an imperfect correlation between the movement in prices of options and the securities underlying them; (2) there may not be a liquid secondary market for all options and, in particular, for OTC options; (3) trading restrictions or limitations may be

10

imposed by an exchange; (4) counterparty risk; and (5) while a Fund will receive a premium when it writes covered call options, it may not participate fully in a rise in the market value of the underlying security.

High Yield Securities . Each High Yield Corporate Bond Fund invests in high yield securities (“junk bonds”), which are debt securities that are rated below investment grade by nationally recognized statistical rating organizations (“NRSROs”), or are unrated securities that the Adviser believes are of comparable quality. Investing in high yield debt securities involves risks that are greater than the risks of investing in higher quality debt securities. These risks include: (i) changes in credit status, including weaker overall credit conditions of issuers and risks of default; (ii) industry, market and economic risk; and (iii) greater price variability and credit risks of certain high yield securities such as zero coupon and payment-in-kind securities. While these risks provide the opportunity for maximizing return over time, they may result in greater volatility of the value of a Fund than a fund that invests in higher-rated securities. Furthermore, the value of high yield securities may be more susceptible to real or perceived adverse economic, company or industry conditions than is the case for higher quality securities. The market values of certain of these lower-rated and unrated debt securities tend to reflect individual corporate developments to a greater extent than do higher-rated securities which react primarily to fluctuations in the general level of interest rates, and tend to be more sensitive to economic conditions than are higher-rated securities. Adverse market, credit or economic conditions could make it difficult at certain times to sell certain high yield securities held by a Fund.

Lending of Portfolio Securities . For the purpose of realizing additional income, a Fund may make secured loans of Fund securities amounting to not more than 33 1/3% of its total assets. Securities loans are made to broker/dealers, institutional investors, or other persons pursuant to agreements requiring that the loans be continuously secured by collateral at least equal at all times to the value of the securities loaned, marked to market on a daily basis. The collateral received will consist of cash, U.S. government securities, letters of credit or such other collateral as may be permitted under its investment program. While the securities are being loaned, a Fund will continue to receive the equivalent of the interest or dividends paid by the issuer on the securities, as well as interest on the investment of the collateral or a fee from the borrower, although a portion can be payable to a collateral agent for certain services. When a Fund invests collateral, the Fund will bear the risk of loss and the risk of loss depends on the nature and type of investment made with the collateral. Costs of underlying securities lending activities are not typically reflected in a Fund’s fee and expense ratios. A Fund has a right to call each loan and obtain the securities on five business days’ notice or, in connection with securities trading on foreign markets, within such longer period of time which coincides with the normal settlement period for purchases and sales of such securities in such foreign markets. A Fund will not have the right to vote securities while they are being loaned, but it will call a loan in anticipation of any important vote. The risks in lending portfolio securities, as with other extensions of secured credit, consist of possible delay in receiving additional collateral or in the recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. Loans will only be made to persons deemed by an Adviser to be of good standing and will not be made unless, in the judgment of an Adviser, the consideration to be earned from such loans would justify the risk.

Leverag e. Certain Funds may use leverage in the limited manner set forth above under “Borrowing.” Leveraging a Fund creates an opportunity for increased net income but, at the same time, creates special risk considerations. For example, leveraging may exaggerate changes in the NAV of a Fund’s shares and in the yield on a Fund’s portfolio. Although the principal of such borrowings will be fixed, a Fund’s assets may change in value during the time the borrowing is outstanding. Since any decline in value of a Fund’s investments will be borne entirely by the Fund’s shareholders (and not by those persons providing the leverage to the Fund), the effect of leverage in a declining market would be a greater decrease in NAV than if the Fund were not so leveraged. Leveraging will create interest and other expenses for a Fund, which can exceed the investment return from the borrowed funds. To the extent the investment return derived from securities purchased with borrowed funds exceeds the interest a Fund will have to pay, the Fund’s investment return will be greater than if leveraging were not used. Conversely, if the investment return from the assets retained with borrowed funds is not sufficient to cover the cost of leveraging, the investment return of the Fund will be less than if leveraging were not used.

Under the 1940 Act, the Fund is required to maintain continuous asset coverage of 300% with respect to borrowings and to sell (within three days) sufficient portfolio holdings to restore such coverage if it should decline to less than 300% due to market fluctuations or otherwise, even if such liquidations of the Fund’s holdings may be disadvantageous from an investment standpoint. The Funds’ policy on borrowing is not intended to limit the ability to pledge assets to secure loans permitted under the Funds’ policies.

11

Repurchase Agreements, Reverse Repurchase Agreements and Dollar Roll Transactions . Each of the Funds may enter into repurchase agreements. Repurchase agreements are similar to loans in many respects. Repurchase agreements are transactions in which the purchaser buys a debt security from a bank or recognized securities dealer and simultaneously commits to resell that security to the bank or dealer at an agreed upon price, date and market rate of interest unrelated to the coupon rate or maturity of the purchased security. If the institution defaults on the repurchase agreement, a Fund will retain possession of the underlying securities. If bankruptcy proceedings are commenced with respect to the seller, realization on the collateral by a Fund may be delayed or limited and the Fund may incur additional costs. In such case, the Fund will be subject to risks associated with changes in market value of the collateral securities. Each Fund intends to enter into repurchase agreements only with banks and broker/dealers believed to present minimal credit risks. Except as described above and elsewhere in this SAI, a Fund may enter into repurchase agreements maturing in less than seven days without limitation.

Repurchase agreements collateralized entirely by cash, U.S. government securities or liquid securities or instruments issued by an issuer that has an exceptionally strong credit quality (“Qualifying Collateral”) generally may be deemed to be “collateralized fully” and may be deemed to be investments in the underlying securities for certain purposes. A Fund may accept collateral other than Qualifying Collateral, including debt securities, equity securities and high yield fixed-income instruments that are rated below investment grade or determined to be of comparable quality (“Alternative Collateral”). Repurchase agreements secured by Alternative Collateral are not deemed to be “collateralized fully” under applicable regulations and the repurchase agreement is therefore considered a separate security issued by the counterparty to the Fund. Accordingly, a Fund must include repurchase agreements that are not “collateralized fully” in its calculations of securities issued by the selling institution held by the Fund for purposes of various portfolio diversification and concentration requirements applicable to the Fund. In addition, Alternative Collateral may not qualify as permitted or appropriate investments for a Fund under the Fund’s investment strategies and limitations. Accordingly, if a counterparty to a repurchase agreement defaults and a Fund takes possession of Alternative Collateral, the Fund may need to promptly dispose of the Alternative Collateral (or other securities held by the Fund, if the Fund exceeds a limitation on a permitted investment by virtue of taking possession of the Alternative Collateral). The Alternative Collateral may be particularly illiquid, especially in times of market volatility or in the case of a counterparty insolvency or bankruptcy, which may restrict a Fund’s ability to dispose of Alternative Collateral received from the counterparty.

Each of the Funds may also enter into reverse repurchase agreements with the same parties with whom they may enter into repurchase agreements. Under a reverse repurchase agreement, a Fund would sell securities and agree to repurchase them at a particular price at a future date. Reverse repurchase agreements involve the risk that the market value of the securities retained in lieu of sale by a Fund may decline below the price of the securities the Fund has sold but is obligated to repurchase. In the event the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, such buyer or its trustee or receiver may receive an extension of time to determine whether to enforce the Fund’s obligation to repurchase the securities, and the Fund’s use of the proceeds of the reverse repurchase agreement may effectively be restricted pending such decision. The Fund will segregate or earmark cash or liquid securities in an amount sufficient to cover its obligation under reverse repurchase agreements. Assets may be segregated with the Fund’s custodian or on the Fund’s books. As noted above under “Borrowing,” investments in reverse repurchase agreements are treated as borrowings and, therefore, are subject to a Fund’s fundamental policy on borrowing.

Shares of Other Investment Companies . Each of the Funds may invest in shares of other investment companies, which may include closed-end funds and exchange-traded funds (“ETFs”).

The investment companies in which the Fund invests may have adopted certain investment restrictions that are more or less restrictive than the Fund’s investment restrictions, which may permit the Fund to engage in investment strategies indirectly that are prohibited under the Fund’s investment restrictions. For example, to the extent the Fund invests in underlying investment companies that concentrate their investments in an industry, a corresponding portion of the Fund’s assets may be indirectly exposed to that particular industry.

12

A Fund may purchase securities of other investment companies to the extent permitted by the 1940 Act, the rules and regulations thereunder and any applicable exemptive relief. It is the Funds’ policy that if shares of a Fund are purchased by another fund (including any other registered open-end investment company or registered unit investment trust advised by Guggenheim Investments or its affiliates) in reliance on Section 12(d)(1)(G) of the 1940 Act, for so long as shares of the Fund are held by such other fund, the Fund will not purchase securities of a registered open-end investment company or registered unit investment trust in reliance on Section 12(d)(1)(F) or Section 12(d)(1)(G) of the 1940 Act.

The main risk of investing in index-based investment companies is the same as investing in a portfolio of securities comprising the index. The market prices of index-based investments will fluctuate in accordance with both changes in the market value of their underlying portfolio securities and due to supply and demand for the instruments on the exchanges on which they are traded. Index-based investments may not replicate exactly the performance of their specified index because of transaction costs and because of the temporary unavailability of certain component securities of the index.

To the extent a Fund invests in other investment companies, it will incur its pro rata share of the underlying investment companies’ expenses (including, for example, investment advisory and other management fees). In addition, a Fund will be subject to the effects of business and regulatory developments that affect an underlying investment company or the investment company industry generally.

Short-Term Instruments . When the Funds experience large cash inflows through the sale of securities and/or creation orders and the fixed income securities that are included in the Funds’ respective Indexes are unavailable in sufficient quantities or at attractive prices, the Funds may hold short-term investments for a limited time at the discretion of the Adviser. Short-term instruments consist of: (1) short-term obligations issued or guaranteed by the U.S. government or any of its agencies or instrumentalities or by any of the states; (2) other short-term debt securities; (3) commercial paper; (4) bank obligations, including negotiable certificates of deposit, time deposits and bankers’ acceptances; (5) repurchase agreements; (6) shares of money market funds; and (7) non-convertible corporate debt securities (e.g., bonds and debentures) with remaining maturities as of the date of purchase of not more than 397 days and that are rated in the top-two short-term categories by two Nationally Recognized Statistical Ratings Organizations (“NRSROs”), or if unrated, deemed to be of equal quality by the Adviser.

Structured Notes . The Funds are permitted to invest in structured notes, which are debt obligations that also contain an embedded derivative component with characteristics that adjust the obligation’s risk/return profile. Generally, the performance of a structured note will track that of the underlying debt obligation and the derivative embedded within it. A Fund has the right to receive periodic interest payments from the issuer of the structured notes at an agreed-upon interest rate and a return of the principal at the maturity date.

Structured notes are typically privately negotiated transactions between two or more parties. A Fund bears the risk that the issuer of the structured note would default or become bankrupt which may result in the loss of principal investment and periodic interest payments expected to be received for the duration of its investment in the structured notes.

In the case of structured notes on credit default swaps a Fund would be subject to the credit risk of the corporate credit instruments underlying the credit default swaps. If one of the underlying corporate credit instruments defaults, the Fund may receive the security or credit instrument that has defaulted, or alternatively a cash settlement may occur, and the Fund’s principal investment in the structured note would be reduced by the corresponding face value of the defaulted security.

The market for structured notes may be, or suddenly can become, illiquid. The other parties to the transaction may be the only investors with sufficient understanding of the derivative to be interested in bidding for it. Changes in liquidity may result in significant, rapid, and unpredictable changes in the prices for structured notes. In certain cases, a market price for a credit-linked security may not be available. The collateral for a structured note may be one or more credit default swaps, which are subject to additional risks.

Swap Agreements . Each Fund may enter into swap agreements, including, but not limited to, total return swaps, index swaps, interest rate swaps, municipal market data rate locks and credit default swaps. A Fund may

utilize swap agreements in an attempt to gain exposure to the securities in a market without actually purchasing those securities, or to hedge a position. Swap agreements are contracts entered into primarily by institutional investors for periods ranging from a day to more than one-year and may be negotiated bilaterally and traded OTC between two parties or, in some instances, must be transacted through a futures commission merchant and cleared through a clearinghouse that serves as a central counterparty. In a standard “swap” transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments. The gross returns to be exchanged or “swapped” between the parties are calculated with respect to a “notional amount,” i.e., the return on or increase in value of a particular dollar amount invested in a “basket” of securities or ETFs. Forms of swap agreements include (i) interest rate caps, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates exceed a specified rate, or “cap,” (ii) interest rate floors, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates fall below a specified level, or “floor,” and (iii) interest rate collars, under which a party sells a cap and purchases a floor or vice versa in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels.

Another form of swap agreement is a credit default swap. A credit default swap enables a Fund to buy or sell protection against a defined credit event of an issuer or a basket of securities or ETFs. Generally, the seller of credit protection against an issuer or basket of securities receives a periodic payment to compensate against potential default events. If a default event occurs, the seller must pay the buyer the full notional value of the reference obligation in exchange for the reference obligation. If no default occurs, the counterparty will pay the stream of payments and have no further obligations to the Fund selling the credit protection.

In contrast, the buyer of a credit default swap would have the right to deliver a referenced debt obligation and receive the par (or other agreed-upon) value of such debt obligation from the counterparty in the event of a default or other credit event (such as a credit downgrade) by the reference issuer, such as a U.S. or foreign corporation, with respect to its debt obligations. In return, the buyer of the credit protection would pay the counterparty a periodic stream of payments over the term of the contract provided that no event of default has occurred. If no default occurs, the counterparty would keep the stream of payments and would have no further obligations to the Fund purchasing the credit protection.

Each Fund also may enhance income by selling credit protection or attempt to mitigate credit risk by buying protection. Credit default swaps could result in losses if the creditworthiness of an issuer or a basket of securities is not accurately evaluated.

Most swap agreements (but generally not credit default swaps) that a Fund might enter into require the parties to calculate the obligations of the parties to the agreement on a “net basis.” Swap agreements may not involve the delivery of securities or other underlying assets. Consequently, a Fund’s obligations (or rights) and risk of loss under such a swap agreement would generally be equal only to the net amount to be paid or received under the agreement based on the relative values of the positions held by each party to the agreement (the “net amount”). Other swap agreements, such as credit default swaps, may require initial premium (discount) payments as well as periodic payments (receipts) related to the interest leg of the swap or to the default of a reference obligation.

Each Fund is required to cover its swaps positions in a manner consistent with the 1940 Act or the rules and SEC interpretations thereunder in order to limit the risk associated with the use of leverage and other related risks. A Fund’s obligations under a swap agreement (other than a CDS for which a Fund is the seller) would be accrued daily (offset against any amounts owing to the Fund) and any accrued but unpaid net amounts owed to a swap counterparty would be covered by segregating assets determined to be liquid. Obligations under swap agreements so covered would not be construed to be “senior securities” for purposes of a Fund’s investment restriction concerning senior securities and, accordingly, would not treat them as subject to a Fund’s borrowing restrictions. For swaps that are not cash settled, each Fund will earmark or segregate cash or liquid assets with a value at least equal to the full notional amount of the swaps (minus any amounts owed to the Fund) or enter into offsetting transactions. For swaps that are cash settled, each Fund may designate or segregate on its records cash or liquid assets equal to the Fund’s next daily marked-to-market net obligations under the swaps, if any, rather than the full notional amount. Such segregation will ensure that a Fund has assets available to satisfy its obligations with respect to the transaction and will limit any potential leveraging of a Fund’s portfolio. By earmarking or designating assets equal to only its net obligation under cash-settled swaps, a Fund will have the ability to employ leverage to a greater extent than if a Fund were required to earmark or segregate assets equal to the full notional amount of such swaps.

Because they may be two party contracts and because they may have terms of greater than seven days, swap agreements may be considered to be illiquid for a Fund’s illiquid investment limitations. A Fund would not enter into any swap agreement unless the Adviser believes that the other party to the transaction is creditworthy. A Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty, or in the case of a credit default swap in which a Fund is selling credit protection, the default of a third party issuer.

Each Fund may enter into swap agreements to invest in a market without owning or taking physical custody of the underlying securities in circumstances in which direct investment is restricted for legal reasons or is otherwise impracticable. The counterparty to any swap agreement would typically be a bank, investment banking firm or broker-dealer or, in the case of a cleared swap, the clearinghouse. The counterparty would generally agree to pay a Fund the amount, if any, by which the notional amount of the swap agreement would have increased in value had it been invested in the particular stocks, plus the dividends that would have been received on those stocks. The Fund would agree to pay to the counterparty a floating rate of interest on the notional amount of the swap agreement plus the amount, if any, by which the notional amount would have decreased in value had it been invested in such stocks. Therefore, the return to a Fund on any swap agreement should be the gain or loss on the notional amount plus dividends on the stocks less the interest paid by the Fund on the notional amount.

Swap agreements typically are settled on a net basis (but generally not credit default swaps), which means that the two payment streams are netted out, with a Fund receiving or paying, as the case may be, only the net amount of the two payments. Payments may be made at the conclusion of a swap agreement or periodically during its term.

Other swap agreements, such as credit default swaps, may require initial premium (discount) payments as well as periodic payments (receipts) related to the interest leg of the swap or to the default of a reference obligation. A Fund would earmark and reserve assets necessary to meet any accrued payment obligations when it is the buyer of a credit default swap. In cases where a Fund is the seller of a credit default swap, if the credit default swap provides for physical settlement, the Fund would be required to earmark and reserve the full notional amount of the credit default swap.

A Fund may also enter into swaps on an index, including credit default index swaps (CDX), which are swaps on an index of credit default swaps. For example, a commercial mortgage-backed index (CMBX) is a type of CDX made up of 25 tranches of commercial mortgage-backed securities rather than CDS. Unlike other CDX contracts where credit events are intended to capture an event of default, CMBX involves a pay-as-you-go settlement process designed to capture non-default events that affect the cash flow of the reference obligation. Pay-as-you-go settlement involves ongoing, two-way payments over the life of a contract between the buyer and the seller of protection and is designed to closely mirror the cash flow of a portfolio of cash commercial mortgage-backed securities.

The swap market has grown substantially in recent years with a large number of banks and investment banking firms acting both as principals and as agents utilizing standardized swap documentation. As a result, the swap market has become relatively liquid in comparison with the markets for other similar instruments that are traded in the OTC market. The Adviser under the supervision of the Board, is responsible for determining and monitoring the liquidity of Fund transactions in swap agreements.

Certain standardized swaps are subject to mandatory central clearing. Central clearing is expected to reduce counterparty credit risk and increase liquidity, but central clearing does not make swap transactions risk-free. The Dodd-Frank Act and related regulatory developments will ultimately require the clearing and exchange-trading of many OTC derivative instruments that the CFTC and SEC recently defined as “swaps.” Mandatory exchange-trading and clearing will occur on a phased-in basis based on the type of market participant and CFTC approval of contracts for central clearing. The Adviser will continue to monitor developments in this area, particularly to the extent regulatory changes affect the ability of the Funds to enter into swap agreements. Depending on a Fund’s size and other factors, the margin required under the rules of the clearinghouse and by the clearing member may be in excess of the collateral required to be posted by a Fund to support its obligations under a similar bilateral swap.

15

However, regulators are expected to adopt rules imposing certain margin requirements, including minimums, on uncleared swaps in the near future, which could change this comparison. Regulators are in the process of developing rules that would require trading and execution of most liquid swaps on trading facilities. Moving trading to an exchange-type system may increase market transparency and liquidity but may require a Fund to incur increased expenses to access the same types of swaps. Rules adopted in 2012 also require centralized reporting of detailed information about many types of cleared and uncleared swaps. Reporting of swap data may result in greater market transparency, but may subject a Fund to additional administrative burdens and the safeguards established to protect trader anonymity may not function as expected. Swaps traded in the over-the-counter market are subject to margin requirements which, once implemented, may increase the cost to the Fund of engaging in such transactions.

The use of swap agreements, including credit default swaps, is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. If a counterparty’s creditworthiness declines, the value of the swap would likely decline. Moreover, there is no guarantee that a Fund could eliminate its exposure under an outstanding swap agreement by entering into an offsetting swap agreement with the same or another party.

PORTFOLIO TURNOVER

Each Fund calculates its portfolio turnover rate by dividing the value of the lesser of purchases or sales of portfolio securities for the fiscal period by the monthly average of the value of portfolio securities owned by the Fund during the fiscal period. A 100% portfolio turnover rate would occur, for example, if all of the portfolio securities (other than short-term securities) were replaced once during the fiscal period. Portfolio turnover rates will vary from year to year, depending on market conditions. At the date of this SAI, each Fund is new and has no operating history, and therefore portfolio turnover information is not yet available.

DISCLOSURE OF PORTFOLIO HOLDINGS

Quarterly Portfolio Schedule. The Trust is required to disclose, after its first and third fiscal quarters, the complete schedule of each Fund’s portfolio holdings with the SEC on Form N-Q. The Trust also discloses a complete schedule of each Fund’s portfolio holdings with the SEC on Form N-CSR after its second and fourth fiscal quarters.

The Trust’s Forms N-Q and Forms N-CSR on behalf of each Fund will be available on the SEC’s website at http://www.sec.gov. The Trust’s Forms N-Q and Forms N-CSR also may be reviewed and copied at the SEC’s Public Reference Room in Washington, D.C., and information on the operation of the Public Reference Room may be obtained by calling 1-202-551-8090. The Trust’s Forms N-Q and Forms N-CSR will be available without charge, upon request, by calling 1-630-933-9600 or 1-800-983-0903 or by writing to PowerShares Exchange-Traded Self-Indexed Fund Trust at 3500 Lacey Road, Suite 700, Downers Grove, Illinois 60515.

Portfolio Holdings Policy.  The Trust has adopted a policy regarding the disclosure of information about the Trust’s portfolio holdings. The Board must approve all material amendments to this policy.

The Funds’ portfolio holdings are disseminated publicly each day that the Funds are open for business through financial reporting and news services, including publicly accessible Internet websites. In addition, for in-kind creations, a basket composition file, which includes the security names and share quantities to deliver in exchange for Shares, together with estimates and actual cash components, is disseminated publicly each day prior to the opening of the Exchange via www.powershares.com/capitalmarkets and the National Securities Clearing Corporation (“NSCC”). The basket represents one Creation Unit of each Fund. The Trust, the Adviser and The Bank of New York Mellon (“BNYM” or the “Administrator”) will not disseminate non-public information concerning the Trust.

Access to information concerning the Funds’ portfolio holdings may be permitted at other times to personnel of third-party service providers, including the Funds’ custodian, transfer agent, auditors and counsel, as may be necessary to conduct business in the ordinary course in a manner consistent with such service providers’ agreements with the Trust on behalf of the Funds.

MANAGEMENT

The primary responsibility of the Board is to represent the interests of the Funds and to provide oversight of the management of the Funds. The Trust currently has eight Trustees. Six Trustees have no affiliation or business connection with the Adviser or any of its affiliated persons and do not own any stock or other securities issued by the Adviser. These are the “non-interested” (as such term is defined under the 1940 Act) or “independent” Trustees (“Independent Trustees”). One Trustee (the “Unaffiliated Trustee”) is an officer of a company that has engaged in securities transactions with clients advised by a sub-adviser to one or more funds in the “Fund Family” (as defined below), which clients do not include any of the Funds, but is not an affiliated person of the Adviser. The remaining Trustee (the “Interested Trustee”) is affiliated with the Adviser.

The Independent Trustees of the Trust, their term of office and length of time served, their principal business occupations during at least the past five years, the number of portfolios in the Fund Complex (defined below) that they oversee and other directorships, if any, that they hold are shown below. The “Fund Complex” includes all open and closed-end funds (including all of their portfolios) advised by the Adviser and any funds that have an investment adviser that is an affiliated person of the Adviser. As of the date of this SAI, the “Fund Family” consists of the Trust and four other exchange-traded fund trusts advised by the Adviser.
