Invesco Emerging Markets Debt Defensive ETF

Invesco Emerging Markets Debt Defensive ETF

Summary Information

Investment Objective

The Invesco Emerging Markets Debt Defensive ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Invesco Emerging Markets Debt Defensive Index (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.

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	Invesco Emerging Markets Debt Defensive ETF Invesco Emerging Markets Debt Defensive ETF
Management Fees	0.29%
Other Expenses	none	[1]
Total Annual Fund Operating Expenses	0.29%

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:

Expense Example	1 Year	3 Years
Invesco Emerging Markets Debt Defensive ETF | Invesco Emerging Markets Debt Defensive ETF | USD ($)	30	93

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 will cause the Fund to incur additional 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 generally will invest at least 80% of its total assets in securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, Invesco Indexing LLC (the “Index Provider”) compiles and maintains the Underlying Index, which is designed to provide exposure to emerging markets debt securities having the highest “quality scores” (within the eligible universe of emerging market debt securities) as determined by the Index Provider using its methodology described below. The Index Provider is affiliated with Invesco Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by sovereign governments, and agencies thereof, of countries that the Index Provider considers to be “emerging market countries” (as of June 15, 2018, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, Israel, Malaysia, Mexico, Morocco, Peru, the Philippines, Poland, Russia, South Africa, Taiwan, Thailand, Turkey, the United Arab Emirates and Vietnam). To be eligible for inclusion in the Underlying Index, bonds must (i) be rated higher than B- (or equivalent) by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), Fitch Ratings Inc. (“Fitch”) or Moody’s Investors Service, Inc. (“Moody’s”) credit rating agencies; (ii) have at least $500 million outstanding, with only the largest five bonds from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Securities issued in accordance with Rule 144A (“Rule 144A securities”) or Regulation S (“Regulation S securities”) under the Securities Act of 1933, as amended (“Securities Act”), and bonds registered with the Securities and Exchange Commission (“SEC”) are all eligible for inclusion in the Underlying Index.

The Index Provider assigns a quality score (“Quality Score”) to each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized by bond type (agency or sovereign), and the Quality Score for each bond is computed as a weighted-average combination of these two factors, with weights of 75% and 25% for maturity and credit rating, respectively.

All eligible securities are ranked by Quality Score. Initially, bonds with Quality Scores in the top 40% of eligible securities are selected for inclusion in the Underlying Index. At each monthly Underlying Index rebalance, any eligible security with a Quality Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index components with a Quality Score in the bottom 40% of eligible securities are removed. The Underlying Index will typically include between 100-300 securities, which are modified market-value weighted.

The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund utilizes a “sampling” methodology to seek to achieve its investment objective.

The Fund is “non-diversified” and therefore is not required to meet certain diversification requirements under the Investment Company Act of 1940, as amended (the “1940 Act”).

Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

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.

Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs, and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that those APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities underlying the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with processing creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, which may be more likely to trade at a premium or discount to net asset value (“NAV”) and to face trading halts and/or delisting. This risk may be heightened for the Fund because it invests in non-U.S. securities, which may have lower trading volumes.

Call Risk. If interest rates fall, it is possible that issuers of callable securities with high interest coupons will “call” (or prepay) their bonds before their maturity date. If an issuer exercised such a call during a period of declining interest rates, the Fund may have to replace such called security with a lower yielding security. If that were to happen, the Fund’s net investment income could fall.

Cash Transaction Risk. Most ETFs generally make in-kind redemptions to avoid being taxed on gains on the distributed portfolio securities at the fund level. However, unlike most ETFs, the Fund currently intends to effect creations and redemptions principally for cash, rather than principally in-kind, due to the nature of the Fund’s investments. As such, the Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. Therefore, the Fund may recognize a capital gain on these sales that might not have been incurred if the Fund had made a redemption in-kind. This may decrease the tax efficiency of the Fund compared to ETFs that utilize an in-kind redemption process and there may be a substantial difference in the after-tax rate of return between the Fund and conventional ETFs.

Changing Foreign Fixed-Income Market Conditions Risk. The current historically low interest rate environment was created in part by foreign central banks keeping rates at, near or below zero. The recent end of various governments’ quantitative easing programs, combined with the increases in such foreign rates, may expose fixed-income markets to heightened volatility and reduced liquidity for certain fixed-income investments, particularly those with longer maturities, although it is difficult to predict the impact of this rate increase and any future rate increases on various markets.

Emerging Markets Sovereign Debt Risk. Government obligors in emerging market countries are among the world’s largest debtors to commercial banks, other governments, international financial organizations and other financial institutions. Historically, certain issuers of the government debt securities in which the Fund may invest have experienced substantial difficulties in meeting their external debt obligations, resulting in defaults on certain obligations and the restructuring of certain indebtedness. Such restructuring arrangements have included obtaining additional credit to finance outstanding obligations and the reduction and rescheduling of payments of interest and principal through the negotiation of new or amended credit agreements.

Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security.

Foreign Investment Risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities. Foreign securities may have relatively low market liquidity, greater market volatility, decreased publicly available information, and less reliable financial information about issuers, and inconsistent and potentially less stringent accounting, auditing and financial reporting requirements and standards of practice comparable to those applicable to domestic issuers. Foreign securities also are subject to the risks of expropriation, nationalization, political instability or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in foreign securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions and higher transactional costs.

Global Bonds Risk. Global bonds are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities, including greater market volatility, the availability of less reliable financial information, higher transactional costs, taxation by foreign governments, decreased market liquidity and political instability.

Index Rebalance Risk. Pursuant to the methodology that the Index Provider uses to maintain the Underlying Index, securities may be frequently added or removed from the Underlying Index during regular Underlying Index rebalances. As a result, to the extent the Fund attempts to replicate the Underlying Index, the Fund may frequently buy or sell securities, increasing portfolio turnover. Higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. Additionally, Underlying Index rebalances may cause the Fund to purchase or 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 these factors, the variation between the Fund’s annual return and the return of the Underlying Index may increase significantly.

Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

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

Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price.

Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV.

Non-Correlation Risk. The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. Because the Fund issues and redeems Creation Units principally for cash, it will incur higher costs in buying and selling securities than if it issued and redeemed Creation Units in-kind. Additionally, the Fund’s use of a representative sampling approach may cause the Fund not to be as well-correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversified Fund Risk. Because the Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.

Non-Investment Grade Securities Risk. Non-investment grade securities are considered speculative and unrated securities of comparable credit quality are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of the non-investment grade securities markets generally, real or perceived adverse economic and competitive industry conditions and less secondary market liquidity. If the issuer of non-investment grade securities defaults, the Fund may incur additional expenses to seek recovery.

Privately Issued Securities Risk. The Fund may invest in privately issued securities, including those that may be resold only in accordance with Rule 144A or Regulation S under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded, and Regulation S securities are securities of U.S. and non-U.S. issuers initially offered and sold outside the United States without registration with the SEC. Accordingly, the liquidity of the market for specific Rule 144A or Regulation S securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund.

Sampling Risk. The Fund’s use of a representative sampling approach will result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development to an issuer of securities that the Fund holds could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater.

Sovereign Debt Risk. Investments in sovereign debt securities involve special risks. The governmental authority that controls the repayment of the debt may be unwilling or unable to repay the principal and/or interest when due in accordance with the terms of such securities due to the extent of its foreign reserves; the availability of sufficient foreign exchange on the date a payment is due; the relative size of the debt service burden to the economy as a whole; or the government debtor’s policy towards the International Monetary Fund and the political constraints to which a government debtor may be subject. If an issuer of sovereign debt defaults on payments of principal and/or interest, the Fund may have limited legal recourse against the issuer and/or guarantor. In certain cases, remedies must be pursued in the courts of the defaulting party itself, and the Fund’s ability to obtain recourse may be limited.

Valuation Risk. Financial information related to securities of non-U.S. issuers may be less reliable than information related to securities of U.S. issuers, which may make it difficult to obtain a current price for a non-U.S. security held by the Fund. In certain circumstances, market quotations may not be readily available for some Fund securities, and those securities may be fair valued. The value established for a security through fair valuation may be different from what would be produced if the security had been valued using market quotations. Fund securities that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. In addition, there is no assurance that the Fund could sell a portfolio security for the value established for it at any time, and it is possible that the Fund would incur a loss because a security is sold at a discount to its established value.

Valuation Time Risk. The Fund will invest in foreign bonds and, because foreign exchanges may be open on days when the Fund does not price its Shares, the value of the non-U.S. securities in the Fund’s portfolio may change on days when you will not be able to purchase or sell your Shares. As a result, trading spreads and the resulting premium or discount on the Shares may widen, and, therefore, increase the difference between the market price of the Shares and the Fund’s NAV of such Shares.

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.invesco.com/ETFs and will provide some indication of the risks of investing in the Fund.

If interest rates fall, it is possible that issuers of callable securities with high interest coupons will “call” (or prepay) their bonds before their maturity date. If an issuer exercised such a call during a period of declining interest rates, the Fund may have to replace such called security with a lower yielding security. If that were to happen, the Fund’s net investment income could fall. Cash Transaction Risk. Most ETFs generally make in-kind redemptions to avoid being taxed on gains on the distributed portfolio securities at the fund level. However, unlike most ETFs, the Fund currently intends to effect creations and redemptions principally for cash, rather than principally in-kind, due to the nature of the Fund’s investments. As such, the Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. Therefore, the Fund may recognize a capital gain on these sales that might not have been incurred if the Fund had made a redemption in-kind. This may decrease the tax efficiency of the Fund compared to ETFs that utilize an in-kind redemption process and there may be a substantial difference in the after-tax rate of return between the Fund and conventional ETFs. Changing Foreign Fixed-Income Market Conditions Risk. The current historically low interest rate environment was created in part by foreign central banks keeping rates at, near or below zero. The recent end of various governments’ quantitative easing programs, combined with the increases in such foreign rates, may expose fixed-income markets to heightened volatility and reduced liquidity for certain fixed-income investments, particularly those with longer maturities, although it is difficult to predict the impact of this rate increase and any future rate increases on various markets. Emerging Markets Sovereign Debt Risk. Government obligors in emerging market countries are among the world’s largest debtors to commercial banks, other governments, international financial organizations and other financial institutions. Historically, certain issuers of the government debt securities in which the Fund may invest have experienced substantial difficulties in meeting their external debt obligations, resulting in defaults on certain obligations and the restructuring of certain indebtedness. Such restructuring arrangements have included obtaining additional credit to finance outstanding obligations and the reduction and rescheduling of payments of interest and principal through the negotiation of new or amended credit agreements. Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Foreign Investment Risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities. Foreign securities may have relatively low market liquidity, greater market volatility, decreased publicly available information, and less reliable financial information about issuers, and inconsistent and potentially less stringent accounting, auditing and financial reporting requirements and standards of practice comparable to those applicable to domestic issuers. Foreign securities also are subject to the risks of expropriation, nationalization, political instability or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in foreign securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions and higher transactional costs. Global Bonds Risk. Global bonds are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities, including greater market volatility, the availability of less reliable financial information, higher transactional costs, taxation by foreign governments, decreased market liquidity and political instability. Index Rebalance Risk. Pursuant to the methodology that the Index Provider uses to maintain the Underlying Index, securities may be frequently added or removed from the Underlying Index during regular Underlying Index rebalances. As a result, to the extent the Fund attempts to replicate the Underlying Index, the Fund may frequently buy or sell securities, increasing portfolio turnover. Higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. Additionally, Underlying Index rebalances may cause the Fund to purchase or 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 these factors, the variation between the Fund’s annual return and the return of the Underlying Index may increase significantly. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Issuer-Specific Changes Risk. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV. Non-Correlation Risk. The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. Because the Fund issues and redeems Creation Units principally for cash, it will incur higher costs in buying and selling securities than if it issued and redeemed Creation Units in-kind. Additionally, the Fund’s use of a representative sampling approach may cause the Fund not to be as well-correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints. Non-Diversified Fund Risk. Because the Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance. Non-Investment Grade Securities Risk. Non-investment grade securities are considered speculative and unrated securities of comparable credit quality are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of the non-investment grade securities markets generally, real or perceived adverse economic and competitive industry conditions and less secondary market liquidity. If the issuer of non-investment grade securities defaults, the Fund may incur additional expenses to seek recovery. Privately Issued Securities Risk. The Fund may invest in privately issued securities, including those that may be resold only in accordance with Rule 144A or Regulation S under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded, and Regulation S securities are securities of U.S. and non-U.S. issuers initially offered and sold outside the United States without registration with the SEC. Accordingly, the liquidity of the market for specific Rule 144A or Regulation S securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund. Sampling Risk. The Fund’s use of a representative sampling approach will result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development to an issuer of securities that the Fund holds could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater. Sovereign Debt Risk. Investments in sovereign debt securities involve special risks. The governmental authority that controls the repayment of the debt may be unwilling or unable to repay the principal and/or interest when due in accordance with the terms of such securities due to the extent of its foreign reserves; the availability of sufficient foreign exchange on the date a payment is due; the relative size of the debt service burden to the economy as a whole; or the government debtor’s policy towards the International Monetary Fund and the political constraints to which a government debtor may be subject. If an issuer of sovereign debt defaults on payments of principal and/or interest, the Fund may have limited legal recourse against the issuer and/or guarantor. In certain cases, remedies must be pursued in the courts of the defaulting party itself, and the Fund’s ability to obtain recourse may be limited. Valuation Risk. Financial information related to securities of non-U.S. issuers may be less reliable than information related to securities of U.S. issuers, which may make it difficult to obtain a current price for a non-U.S. security held by the Fund. In certain circumstances, market quotations may not be readily available for some Fund securities, and those securities may be fair valued. The value established for a security through fair valuation may be different from what would be produced if the security had been valued using market quotations. Fund securities that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. In addition, there is no assurance that the Fund could sell a portfolio security for the value established for it at any time, and it is possible that the Fund would incur a loss because a security is sold at a discount to its established value. Valuation Time Risk. The Fund will invest in foreign bonds and, because foreign exchanges may be open on days when the Fund does not price its Shares, the value of the non-U.S. securities in the Fund’s portfolio may change on days when you will not be able to purchase or sell your Shares. As a result, trading spreads and the resulting premium or discount on the Shares may widen, and, therefore, increase the difference between the market price of the Shares and the Fund’s NAV of such Shares.

Invesco Emerging Markets Debt Value ETF

Invesco Emerging Markets Debt Value ETF

Summary Information

Investment Objective

The Invesco Emerging Markets Debt Value ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Invesco Emerging Markets Debt Value Index (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.

Annual Fund Operating Expenses

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 will cause the Fund to incur additional 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 generally will invest at least 80% of its total assets in securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, Invesco Indexing LLC (the “Index Provider”) compiles and maintains the Underlying Index, which is designed to provide exposure to higher value, emerging markets debt securities. Higher value bonds are characterized as those with higher yields that may provide greater returns in certain markets. In addition, the Underlying Index seeks to incorporate securities with the highest “quality scores” (within the eligible universe of emerging market debt securities) as determined by the Index Provider using its methodology described below. The Index Provider is affiliated with Invesco Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by sovereign governments, and agencies thereof, of countries that the Index Provider considers to be “emerging market countries” (as of June 15, 2018, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, Israel, Malaysia, Mexico, Morocco, Peru, the Philippines, Poland, Russia, South Africa, Taiwan, Thailand, Turkey, the United Arab Emirates and Vietnam). To be eligible for inclusion in the Underlying Index, bonds must (i) be rated higher than B- (or equivalent) by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), Fitch Ratings Inc. (“Fitch”) or Moody’s Investors Service, Inc. (“Moody’s”) credit rating agencies; (ii) have at least $500 million outstanding, with only the largest five bonds from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Securities issued in accordance with Rule 144A (“Rule 144A securities”) or Regulation S (“Reg S securities”) under the Securities Act of 1933, as amended (“Securities Act”), and bonds registered with the Securities and Exchange Commission (“SEC”) are all eligible for inclusion in the Underlying Index.

The Index Provider assigns a quality adjusted value score (“QAV Score”) to each eligible bond, which is calculated based on a combination of value and quality factors or characteristics. With respect to value, a value score (“Value Score”) is assigned to each eligible bond based on the bond’s option adjusted spread (“OAS”). Specifically, the Value Score for each bond is calculated as its percentile ranked OAS within its bond type (agency or sovereign), region and credit rating category. With respect to credit category, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The bond is then assigned to one of six credit rating categories, as established by the Index Provider. Bonds are also separately ranked by OAS solely within their bond type category. If fewer than three bonds are available within a bond type, region or credit rating, then the Value Score for all bonds in the grouping is replaced with the percentile rank based on credit rating only. The Value Scores are then standardized.

The Index Provider also calculates a quality score (“Quality Score”) for each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized by bond type (agency or sovereign), and the Quality Score for each bond is computed as a weighted-average combination of these two factors, with weights of 75% and 25% for maturity and credit rating, respectively.

Once a Value Score and Quality Score are assigned to eligible bonds, the QAV Score is calculated as a weighted-average combination of the two scores, with 90% and 10% weights applied to the Value Score and Quality Score, respectively.

All eligible securities are ranked by the QAV Score. Initially, bonds with QAV Scores in the top 40% of eligible securities are selected for inclusion in the Underlying Index. At each monthly Underlying Index rebalance, any eligible security with a QAV Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index components with a QAV Score in the bottom 40% of eligible securities are removed. The Underlying Index will typically include between 100-300 securities, which are modified market-value weighted.

The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund utilizes a “sampling” methodology to seek to achieve its investment objective.

The Fund is “non-diversified” and therefore is not required to meet certain diversification requirements under the Investment Company Act of 1940, as amended (the “1940 Act”).

Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

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.

Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs, and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that those APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities underlying the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with processing creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, which may be more likely to trade at a premium or discount to net asset value (“NAV”) and to face trading halts and/or delisting. This risk may be heightened for the Fund because it invests in non-U.S. securities, which may have lower trading volumes.

Call Risk. If interest rates fall, it is possible that issuers of callable securities with high interest coupons will “call” (or prepay) their bonds before their maturity date. If an issuer exercised such a call during a period of declining interest rates, the Fund may have to replace such called security with a lower yielding security. If that were to happen, the Fund’s net investment income could fall.

Cash Transaction Risk. Most ETFs generally make in-kind redemptions to avoid being taxed on gains on the distributed portfolio securities at the fund level. However, unlike most ETFs, the Fund currently intends to effect creations and redemptions principally for cash, rather than principally in-kind, due to the nature of the Fund’s investments. As such, the Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. Therefore, the Fund may recognize a capital gain on these sales that might not have been incurred if the Fund had made a redemption in-kind. This may decrease the tax efficiency of the Fund compared to ETFs that utilize an in-kind redemption process and there may be a substantial difference in the after-tax rate of return between the Fund and conventional ETFs.

Changing Foreign Fixed-Income Market Conditions Risk. The current historically low interest rate environment was created in part by foreign central banks keeping rates at, near or below zero. The recent end of various governments’ quantitative easing programs, combined with the increases in such foreign rates, may expose fixed-income markets to heightened volatility and reduced liquidity for certain fixed-income investments, particularly those with longer maturities, although it is difficult to predict the impact of this rate increase and any future rate increases on various markets.

Emerging Markets Sovereign Debt Risk. Government obligors in emerging market countries are among the world’s largest debtors to commercial banks, other governments, international financial organizations and other financial institutions. Historically, certain issuers of the government debt securities in which the Fund may invest have experienced substantial difficulties in meeting their external debt obligations, resulting in defaults on certain obligations and the restructuring of certain indebtedness. Such restructuring arrangements have included obtaining additional credit to finance outstanding obligations and the reduction and rescheduling of payments of interest and principal through the negotiation of new or amended credit agreements.

Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security.

Foreign Investment Risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities. Foreign securities may have relatively low market liquidity, greater market volatility, decreased publicly available information, and less reliable financial information about issuers, and inconsistent and potentially less stringent accounting, auditing and financial reporting requirements and standards of practice comparable to those applicable to domestic issuers. Foreign securities also are subject to the risks of expropriation, nationalization, political instability or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in foreign securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions and higher transactional costs.

Global Bonds Risk. Global bonds are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities, including greater market volatility, the availability of less reliable financial information, higher transactional costs, taxation by foreign governments, decreased market liquidity and political instability.

Index Rebalance Risk. Pursuant to the methodology that the Index Provider uses to maintain the Underlying Index, securities may be frequently added or removed from the Underlying Index during regular Underlying Index rebalances. As a result, to the extent the Fund attempts to replicate the Underlying Index, the Fund may frequently buy or sell securities, increasing portfolio turnover. Higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. Additionally, Underlying Index rebalances may cause the Fund to purchase or 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 these factors, the variation between the Fund’s annual return and the return of the Underlying Index may increase significantly.

Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

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

Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price.

Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV.

Non-Correlation Risk. The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. Because the Fund issues and redeems Creation Units principally for cash, it will incur higher costs in buying and selling securities than if it issued and redeemed Creation Units in-kind. Additionally, the Fund’s use of a representative sampling approach may cause the Fund not to be as well-correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversified Fund Risk. Because the Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.

Non-Investment Grade Securities Risk. Non-investment grade securities are considered speculative and unrated securities of comparable credit quality are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of the non-investment grade securities markets generally, real or perceived adverse economic and competitive industry conditions and less secondary market liquidity. If the issuer of non-investment grade securities defaults, the Fund may incur additional expenses to seek recovery.

Privately Issued Securities Risk. The Fund may invest in privately issued securities, including those that may be resold only in accordance with Rule 144A or Regulation S under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded, and Regulation S securities are securities of U.S. and non-U.S. issuers initially offered and sold outside the United States without registration with the SEC. Accordingly, the liquidity of the market for specific Rule 144A or Regulation S securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund.

Sampling Risk. The Fund’s use of a representative sampling approach will result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development to an issuer of securities that the Fund holds could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater.

Sovereign Debt Risk. Investments in sovereign debt securities involve special risks. The governmental authority that controls the repayment of the debt may be unwilling or unable to repay the principal and/or interest when due in accordance with the terms of such securities due to the extent of its foreign reserves; the availability of sufficient foreign exchange on the date a payment is due; the relative size of the debt service burden to the economy as a whole; or the government debtor’s policy towards the International Monetary Fund and the political constraints to which a government debtor may be subject. If an issuer of sovereign debt defaults on payments of principal and/or interest, the Fund may have limited legal recourse against the issuer and/or guarantor. In certain cases, remedies must be pursued in the courts of the defaulting party itself, and the Fund’s ability to obtain recourse may be limited.

Valuation Risk. Financial information related to securities of non-U.S. issuers may be less reliable than information related to securities of U.S. issuers, which may make it difficult to obtain a current price for a non-U.S. security held by the Fund. In certain circumstances, market quotations may not be readily available for some Fund securities, and those securities may be fair valued. The value established for a security through fair valuation may be different from what would be produced if the security had been valued using market quotations. Fund securities that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. In addition, there is no assurance that the Fund could sell a portfolio security for the value established for it at any time, and it is possible that the Fund would incur a loss because a security is sold at a discount to its established value.

Valuation Time Risk. The Fund will invest in foreign bonds and, because foreign exchanges may be open on days when the Fund does not price its Shares, the value of the non-U.S. securities in the Fund’s portfolio may change on days when you will not be able to purchase or sell your Shares. As a result, trading spreads and the resulting premium or discount on the Shares may widen, and, therefore, increase the difference between the market price of the Shares and the Fund’s NAV of such Shares.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, Invesco Indexing LLC (the “Index Provider”) compiles and maintains the Underlying Index, which is designed to provide exposure to higher value, emerging markets debt securities. Higher value bonds are characterized as those with higher yields that may provide greater returns in certain markets. In addition, the Underlying Index seeks to incorporate securities with the highest “quality scores” (within the eligible universe of emerging market debt securities) as determined by the Index Provider using its methodology described below. The Index Provider is affiliated with Invesco Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”). In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by sovereign governments, and agencies thereof, of countries that the Index Provider considers to be “emerging market countries” (as of June 15, 2018, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, Israel, Malaysia, Mexico, Morocco, Peru, the Philippines, Poland, Russia, South Africa, Taiwan, Thailand, Turkey, the United Arab Emirates and Vietnam). To be eligible for inclusion in the Underlying Index, bonds must (i) be rated higher than B- (or equivalent) by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), Fitch Ratings Inc. (“Fitch”) or Moody’s Investors Service, Inc. (“Moody’s”) credit rating agencies; (ii) have at least $500 million outstanding, with only the largest five bonds from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Securities issued in accordance with Rule 144A (“Rule 144A securities”) or Regulation S (“Reg S securities”) under the Securities Act of 1933, as amended (“Securities Act”), and bonds registered with the Securities and Exchange Commission (“SEC”) are all eligible for inclusion in the Underlying Index. The Index Provider assigns a quality adjusted value score (“QAV Score”) to each eligible bond, which is calculated based on a combination of value and quality factors or characteristics. With respect to value, a value score (“Value Score”) is assigned to each eligible bond based on the bond’s option adjusted spread (“OAS”). Specifically, the Value Score for each bond is calculated as its percentile ranked OAS within its bond type (agency or sovereign), region and credit rating category. With respect to credit category, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The bond is then assigned to one of six credit rating categories, as established by the Index Provider. Bonds are also separately ranked by OAS solely within their bond type category. If fewer than three bonds are available within a bond type, region or credit rating, then the Value Score for all bonds in the grouping is replaced with the percentile rank based on credit rating only. The Value Scores are then standardized. The Index Provider also calculates a quality score (“Quality Score”) for each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized by bond type (agency or sovereign), and the Quality Score for each bond is computed as a weighted-average combination of these two factors, with weights of 75% and 25% for maturity and credit rating, respectively. Once a Value Score and Quality Score are assigned to eligible bonds, the QAV Score is calculated as a weighted-average combination of the two scores, with 90% and 10% weights applied to the Value Score and Quality Score, respectively. All eligible securities are ranked by the QAV Score. Initially, bonds with QAV Scores in the top 40% of eligible securities are selected for inclusion in the Underlying Index. At each monthly Underlying Index rebalance, any eligible security with a QAV Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index components with a QAV Score in the bottom 40% of eligible securities are removed. The Underlying Index will typically include between 100-300 securities, which are modified market-value weighted. The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund utilizes a “sampling” methodology to seek to achieve its investment objective. The Fund is “non-diversified” and therefore is not required to meet certain diversification requirements under the Investment Company Act of 1940, as amended (the “1940 Act”). Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	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. Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs, and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that those APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities underlying the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with processing creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, which may be more likely to trade at a premium or discount to net asset value (“NAV”) and to face trading halts and/or delisting. This risk may be heightened for the Fund because it invests in non-U.S. securities, which may have lower trading volumes. Call Risk. If interest rates fall, it is possible that issuers of callable securities with high interest coupons will “call” (or prepay) their bonds before their maturity date. If an issuer exercised such a call during a period of declining interest rates, the Fund may have to replace such called security with a lower yielding security. If that were to happen, the Fund’s net investment income could fall. Cash Transaction Risk. Most ETFs generally make in-kind redemptions to avoid being taxed on gains on the distributed portfolio securities at the fund level. However, unlike most ETFs, the Fund currently intends to effect creations and redemptions principally for cash, rather than principally in-kind, due to the nature of the Fund’s investments. As such, the Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. Therefore, the Fund may recognize a capital gain on these sales that might not have been incurred if the Fund had made a redemption in-kind. This may decrease the tax efficiency of the Fund compared to ETFs that utilize an in-kind redemption process and there may be a substantial difference in the after-tax rate of return between the Fund and conventional ETFs. Changing Foreign Fixed-Income Market Conditions Risk. The current historically low interest rate environment was created in part by foreign central banks keeping rates at, near or below zero. The recent end of various governments’ quantitative easing programs, combined with the increases in such foreign rates, may expose fixed-income markets to heightened volatility and reduced liquidity for certain fixed-income investments, particularly those with longer maturities, although it is difficult to predict the impact of this rate increase and any future rate increases on various markets. Emerging Markets Sovereign Debt Risk. Government obligors in emerging market countries are among the world’s largest debtors to commercial banks, other governments, international financial organizations and other financial institutions. Historically, certain issuers of the government debt securities in which the Fund may invest have experienced substantial difficulties in meeting their external debt obligations, resulting in defaults on certain obligations and the restructuring of certain indebtedness. Such restructuring arrangements have included obtaining additional credit to finance outstanding obligations and the reduction and rescheduling of payments of interest and principal through the negotiation of new or amended credit agreements. Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Foreign Investment Risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities. Foreign securities may have relatively low market liquidity, greater market volatility, decreased publicly available information, and less reliable financial information about issuers, and inconsistent and potentially less stringent accounting, auditing and financial reporting requirements and standards of practice comparable to those applicable to domestic issuers. Foreign securities also are subject to the risks of expropriation, nationalization, political instability or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in foreign securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions and higher transactional costs. Global Bonds Risk. Global bonds are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities, including greater market volatility, the availability of less reliable financial information, higher transactional costs, taxation by foreign governments, decreased market liquidity and political instability. Index Rebalance Risk. Pursuant to the methodology that the Index Provider uses to maintain the Underlying Index, securities may be frequently added or removed from the Underlying Index during regular Underlying Index rebalances. As a result, to the extent the Fund attempts to replicate the Underlying Index, the Fund may frequently buy or sell securities, increasing portfolio turnover. Higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. Additionally, Underlying Index rebalances may cause the Fund to purchase or 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 these factors, the variation between the Fund’s annual return and the return of the Underlying Index may increase significantly. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Issuer-Specific Changes Risk. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV. Non-Correlation Risk. The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. Because the Fund issues and redeems Creation Units principally for cash, it will incur higher costs in buying and selling securities than if it issued and redeemed Creation Units in-kind. Additionally, the Fund’s use of a representative sampling approach may cause the Fund not to be as well-correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints. Non-Diversified Fund Risk. Because the Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance. Non-Investment Grade Securities Risk. Non-investment grade securities are considered speculative and unrated securities of comparable credit quality are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of the non-investment grade securities markets generally, real or perceived adverse economic and competitive industry conditions and less secondary market liquidity. If the issuer of non-investment grade securities defaults, the Fund may incur additional expenses to seek recovery. Privately Issued Securities Risk. The Fund may invest in privately issued securities, including those that may be resold only in accordance with Rule 144A or Regulation S under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded, and Regulation S securities are securities of U.S. and non-U.S. issuers initially offered and sold outside the United States without registration with the SEC. Accordingly, the liquidity of the market for specific Rule 144A or Regulation S securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund. Sampling Risk. The Fund’s use of a representative sampling approach will result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development to an issuer of securities that the Fund holds could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater. Sovereign Debt Risk. Investments in sovereign debt securities involve special risks. The governmental authority that controls the repayment of the debt may be unwilling or unable to repay the principal and/or interest when due in accordance with the terms of such securities due to the extent of its foreign reserves; the availability of sufficient foreign exchange on the date a payment is due; the relative size of the debt service burden to the economy as a whole; or the government debtor’s policy towards the International Monetary Fund and the political constraints to which a government debtor may be subject. If an issuer of sovereign debt defaults on payments of principal and/or interest, the Fund may have limited legal recourse against the issuer and/or guarantor. In certain cases, remedies must be pursued in the courts of the defaulting party itself, and the Fund’s ability to obtain recourse may be limited. Valuation Risk. Financial information related to securities of non-U.S. issuers may be less reliable than information related to securities of U.S. issuers, which may make it difficult to obtain a current price for a non-U.S. security held by the Fund. In certain circumstances, market quotations may not be readily available for some Fund securities, and those securities may be fair valued. The value established for a security through fair valuation may be different from what would be produced if the security had been valued using market quotations. Fund securities that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. In addition, there is no assurance that the Fund could sell a portfolio security for the value established for it at any time, and it is possible that the Fund would incur a loss because a security is sold at a discount to its established value. Valuation Time Risk. The Fund will invest in foreign bonds and, because foreign exchanges may be open on days when the Fund does not price its Shares, the value of the non-U.S. securities in the Fund’s portfolio may change on days when you will not be able to purchase or sell your Shares. As a result, trading spreads and the resulting premium or discount on the Shares may widen, and, therefore, increase the difference between the market price of the Shares and the Fund’s NAV of such Shares.
Risk Lose Money [Text]	rr_RiskLoseMoney	The Shares will change in value, and you could lose money by investing in the Fund.
Risk Nondiversified Status [Text]	rr_RiskNondiversifiedStatus	Non-Diversified Fund Risk. Because the Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund.

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 will cause the Fund to incur additional 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 generally will invest at least 80% of its total assets in securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, Invesco Indexing LLC (the “Index Provider”) compiles and maintains the Underlying Index, which is designed to provide exposure to U.S. high yield bonds (commonly known as “junk bonds”) having the highest “quality scores” (within the eligible universe of U.S. high yield bonds) as determined by the Index Provider using its methodology described below. The Index Provider is affiliated with Invesco Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by U.S. companies. To be eligible for inclusion in the Underlying Index, bonds must (i) be rated higher than B- and lower than BBB- (or equivalent) by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), Fitch Ratings Inc. (“Fitch”) or Moody’s Investors Service, Inc. (“Moody’s”) credit rating agencies; (ii) have at least $400 million outstanding, with only the largest bond from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Securities issued in accordance with Rule 144A (“Rule 144A securities”) under the Securities Act of 1933, as amended (“Securities Act”), bonds registered with the Securities and Exchange Commission (“SEC”), publicly underwritten medium-term notes and Eurodollar bonds are all eligible for inclusion in the Underlying Index.

The Index Provider assigns a quality score (“Quality Score”) to each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized across the universe of eligible bonds, and the Quality Score for each bond is computed as an equally-weighted combination of these two factors.

All eligible securities are ranked by Quality Score. Initially, bonds with Quality Scores in the top 40% of eligible securities are selected for inclusion in the Underlying Index. At each monthly Underlying Index rebalance, any eligible security with a Quality Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index components with a quality score in the bottom 50% of eligible securities are removed. The Underlying Index will typically include between 100-300 securities, which are equally weighted.

The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund utilizes a “sampling” methodology to seek to achieve its investment objective.

The Fund is “non-diversified” and therefore is not required to meet certain diversification requirements under the Investment Company Act of 1940, as amended (the “1940 Act”).

Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries. As of the date of this prospectus, a significant portion of the Underlying Index is represented by the financial sector and, accordingly, the Adviser anticipates that the Fund may concentrate its investments in that sector. The Fund’s portfolio holdings, and the extent to which it concentrates in any industry or group of industries, are likely to change over time.

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.

Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs, and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that those APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities underlying the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with processing creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, which may be more likely to trade at a premium or discount to net asset value (“NAV”) and to face trading halts and/or delisting. This risk may be heightened for the Fund because it invests in non-U.S. securities, which may have lower trading volumes.

Call Risk. If interest rates fall, it is possible that issuers of callable securities with high interest coupons will “call” (or prepay) their bonds before their maturity date. If an issuer exercised such a call during a period of declining interest rates, the Fund may have to replace such called security with a lower yielding security. If that were to happen, the Fund’s net investment income could fall.

Cash Transaction Risk. Most ETFs generally make in-kind redemptions to avoid being taxed on gains on the distributed portfolio securities at the fund level. However, unlike most ETFs, the Fund currently intends to effect creations and redemptions principally for cash, rather than principally in-kind, due to the nature of the Fund’s investments. As such, the Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. Therefore, the Fund may recognize a capital gain on these sales that might not have been incurred if the Fund had made a redemption in-kind. This may decrease the tax efficiency of the Fund compared to ETFs that utilize an in-kind redemption process and there may be a substantial difference in the after-tax rate of return between the Fund and conventional ETFs.

Changing U.S. Fixed-Income Market Conditions Risk. The current historically low interest rate environment was created in part by the Federal Reserve Board (“FRB”) keeping the federal funds rates at, near or below zero. The “tapering” in 2015 of the FRB’s quantitative easing program, combined with the FRB’s recent raising of the target range for the Federal Funds Rate may expose fixed-income markets to heightened volatility and reduced liquidity for certain fixed-income investments, particularly those with longer maturities, although it is difficult to predict the impact of this rate increase and any future rate increases on various markets. In addition, decreases in fixed-income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed-income markets. As a result, the value of the Fund’s investments and share price may decline. Changes in FRB policies could also result in higher than normal shareholder redemptions, which could potentially increase portfolio turnover rate and the Fund’s transaction costs.

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.

Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security.

Index Rebalance Risk. Pursuant to the methodology that the Index Provider uses to maintain the Underlying Index, securities may be frequently added or removed from the Underlying Index during regular Underlying Index rebalances. As a result, to the extent the Fund attempts to replicate the Underlying Index, the Fund may frequently buy or sell securities, increasing portfolio turnover. Higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. Additionally, Underlying Index rebalances may cause the Fund to purchase or 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 these factors, the variation between the Fund’s annual return and the return of the Underlying Index may increase significantly.

Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Industry Concentration Risk. The Underlying Index from time to time may be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries or sectors. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or sector may be out of favor and underperform other industries or the market as a whole.

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

Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price.

Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV.

Non-Correlation Risk. The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. Because the Fund issues and redeems Creation Units principally for cash, it will incur higher costs in buying and selling securities than if it issued and redeemed Creation Units in-kind. Additionally, the Fund’s use of a representative sampling approach may cause the Fund not to be as well-correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversified Fund Risk. Because the Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.

Non-Investment Grade Securities Risk. Non-investment grade securities are considered speculative and unrated securities of comparable credit quality are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of the non-investment grade securities markets generally, real or perceived adverse economic and competitive industry conditions and less secondary market liquidity. If the issuer of non-investment grade securities defaults, the Fund may incur additional expenses to seek recovery.

Privately Issued Securities Risk. The Fund may invest in privately issued securities, including those that may be resold only in accordance with Rule 144A or Regulation S under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded, and Regulation S securities are securities of U.S. and non-U.S. issuers initially offered and sold outside the United States without registration with the SEC. Accordingly, the liquidity of the market for specific Rule 144A or Regulation S securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund.

Sampling Risk. The Fund’s use of a representative sampling approach will result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development to an issuer of securities that the Fund holds could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, Invesco Indexing LLC (the “Index Provider”) compiles and maintains the Underlying Index, which is designed to provide exposure to U.S. high yield bonds (commonly known as “junk bonds”) having the highest “quality scores” (within the eligible universe of U.S. high yield bonds) as determined by the Index Provider using its methodology described below. The Index Provider is affiliated with Invesco Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”). In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by U.S. companies. To be eligible for inclusion in the Underlying Index, bonds must (i) be rated higher than B- and lower than BBB- (or equivalent) by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), Fitch Ratings Inc. (“Fitch”) or Moody’s Investors Service, Inc. (“Moody’s”) credit rating agencies; (ii) have at least $400 million outstanding, with only the largest bond from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Securities issued in accordance with Rule 144A (“Rule 144A securities”) under the Securities Act of 1933, as amended (“Securities Act”), bonds registered with the Securities and Exchange Commission (“SEC”), publicly underwritten medium-term notes and Eurodollar bonds are all eligible for inclusion in the Underlying Index. The Index Provider assigns a quality score (“Quality Score”) to each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized across the universe of eligible bonds, and the Quality Score for each bond is computed as an equally-weighted combination of these two factors. All eligible securities are ranked by Quality Score. Initially, bonds with Quality Scores in the top 40% of eligible securities are selected for inclusion in the Underlying Index. At each monthly Underlying Index rebalance, any eligible security with a Quality Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index components with a quality score in the bottom 50% of eligible securities are removed. The Underlying Index will typically include between 100-300 securities, which are equally weighted. The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund utilizes a “sampling” methodology to seek to achieve its investment objective. The Fund is “non-diversified” and therefore is not required to meet certain diversification requirements under the Investment Company Act of 1940, as amended (the “1940 Act”). Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries. As of the date of this prospectus, a significant portion of the Underlying Index is represented by the financial sector and, accordingly, the Adviser anticipates that the Fund may concentrate its investments in that sector. The Fund’s portfolio holdings, and the extent to which it concentrates in any industry or group of industries, are likely to change over time.

Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	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. Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs, and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that those APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities underlying the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with processing creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, which may be more likely to trade at a premium or discount to net asset value (“NAV”) and to face trading halts and/or delisting. This risk may be heightened for the Fund because it invests in non-U.S. securities, which may have lower trading volumes. Call Risk. If interest rates fall, it is possible that issuers of callable securities with high interest coupons will “call” (or prepay) their bonds before their maturity date. If an issuer exercised such a call during a period of declining interest rates, the Fund may have to replace such called security with a lower yielding security. If that were to happen, the Fund’s net investment income could fall. Cash Transaction Risk. Most ETFs generally make in-kind redemptions to avoid being taxed on gains on the distributed portfolio securities at the fund level. However, unlike most ETFs, the Fund currently intends to effect creations and redemptions principally for cash, rather than principally in-kind, due to the nature of the Fund’s investments. As such, the Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. Therefore, the Fund may recognize a capital gain on these sales that might not have been incurred if the Fund had made a redemption in-kind. This may decrease the tax efficiency of the Fund compared to ETFs that utilize an in-kind redemption process and there may be a substantial difference in the after-tax rate of return between the Fund and conventional ETFs. Changing U.S. Fixed-Income Market Conditions Risk. The current historically low interest rate environment was created in part by the Federal Reserve Board (“FRB”) keeping the federal funds rates at, near or below zero. The “tapering” in 2015 of the FRB’s quantitative easing program, combined with the FRB’s recent raising of the target range for the Federal Funds Rate may expose fixed-income markets to heightened volatility and reduced liquidity for certain fixed-income investments, particularly those with longer maturities, although it is difficult to predict the impact of this rate increase and any future rate increases on various markets. In addition, decreases in fixed-income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed-income markets. As a result, the value of the Fund’s investments and share price may decline. Changes in FRB policies could also result in higher than normal shareholder redemptions, which could potentially increase portfolio turnover rate and the Fund’s transaction costs. 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. Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Index Rebalance Risk. Pursuant to the methodology that the Index Provider uses to maintain the Underlying Index, securities may be frequently added or removed from the Underlying Index during regular Underlying Index rebalances. As a result, to the extent the Fund attempts to replicate the Underlying Index, the Fund may frequently buy or sell securities, increasing portfolio turnover. Higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. Additionally, Underlying Index rebalances may cause the Fund to purchase or 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 these factors, the variation between the Fund’s annual return and the return of the Underlying Index may increase significantly. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Industry Concentration Risk. The Underlying Index from time to time may be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries or sectors. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or sector may be out of favor and underperform other industries or the market as a whole. Issuer-Specific Changes Risk. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV. Non-Correlation Risk. The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. Because the Fund issues and redeems Creation Units principally for cash, it will incur higher costs in buying and selling securities than if it issued and redeemed Creation Units in-kind. Additionally, the Fund’s use of a representative sampling approach may cause the Fund not to be as well-correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints. Non-Diversified Fund Risk. Because the Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance. Non-Investment Grade Securities Risk. Non-investment grade securities are considered speculative and unrated securities of comparable credit quality are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of the non-investment grade securities markets generally, real or perceived adverse economic and competitive industry conditions and less secondary market liquidity. If the issuer of non-investment grade securities defaults, the Fund may incur additional expenses to seek recovery. Privately Issued Securities Risk. The Fund may invest in privately issued securities, including those that may be resold only in accordance with Rule 144A or Regulation S under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded, and Regulation S securities are securities of U.S. and non-U.S. issuers initially offered and sold outside the United States without registration with the SEC. Accordingly, the liquidity of the market for specific Rule 144A or Regulation S securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund. Sampling Risk. The Fund’s use of a representative sampling approach will result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development to an issuer of securities that the Fund holds could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index.

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 will cause the Fund to incur additional 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 generally will invest at least 80% of its total assets in securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, Invesco Indexing LLC (the “Index Provider”) compiles and maintains the Underlying Index, which is designed to provide exposure to higher value, U.S. high yield bonds (commonly known as “junk bonds”). Higher value bonds are characterized as those with higher yields that may provide greater returns in certain markets. In addition, the Underlying Index seeks to incorporate securities with the highest “quality scores” (within the eligible universe of U.S. high yield bonds) as determined by the Index Provider using its methodology described below. The Index Provider is affiliated with Invesco Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by U.S. companies. To be eligible for inclusion in the Underlying Index, bonds must (i) be rated higher than B- and lower than BBB- (or equivalent) by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), Fitch Ratings Inc. (“Fitch”) or Moody’s Investors Service, Inc. (“Moody’s”) credit rating agencies; (ii) have at least $400 million outstanding, with only the largest bond from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Securities issued in accordance with Rule 144A (“Rule 144A securities”) under the Securities Act of 1933, as amended (“Securities Act”), bonds registered with the Securities and Exchange Commission (“SEC”), publicly underwritten medium-term notes and Eurodollar bonds are all eligible for inclusion in the Underlying Index.

The Index Provider assigns a quality adjusted value score (“QAV Score”) to each eligible bond, which is calculated based on a combination of value and quality factors or characteristics. With respect to value, a value score (“Value Score”) is assigned to each eligible bond based on the bond’s option adjusted spread (“OAS”). Specifically, the Value Score for each bond is calculated as its percentile ranked OAS within its sector and credit rating category. With respect to credit category, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The bond is then assigned to one of six credit rating categories, as established by the Index Provider. Bonds are also separately ranked by OAS solely within their credit rating category. If fewer than three bonds are available within a sector or credit rating, then the Value Score for all bonds in the grouping is replaced with the percentile rank based on credit rating only. If fewer than three bonds are available within a credit rating category, then the bonds in that credit rating category are removed from Underlying Index eligibility. The Value Scores are then standardized.

The Index Provider also calculates a quality score (“Quality Score”) for each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized across the universe of eligible bonds, and the Quality Score for each bond is computed as an equally-weighted combination of these two factors.

Once a Value Score and Quality Score are assigned to eligible bonds, the QAV Score is calculated as a weighted-average combination of the two scores, with 90% and 10% weights applied to the Value Score and Quality Score, respectively.

All eligible securities are ranked by the QAV Score. Initially, bonds with QAV Scores in the top 40% of eligible securities are selected for inclusion in the Underlying Index. At each monthly Underlying Index rebalance, any eligible security with a QAV Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index components with a QAV Score in the bottom 50% of eligible securities are removed. The Underlying Index will typically include between 100-300 securities, which are equally weighted.

The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund utilizes a “sampling” methodology to seek to achieve its investment objective.

The Fund is “non-diversified” and therefore is not required to meet certain diversification requirements under the Investment Company Act of 1940, as amended (the “1940 Act”).

Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

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.

Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs, and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that those APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities underlying the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with processing creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, which may be more likely to trade at a premium or discount to net asset value (“NAV”) and to face trading halts and/or delisting. This risk may be heightened for the Fund because it invests in non-U.S. securities, which may have lower trading volumes.

Call Risk. If interest rates fall, it is possible that issuers of callable securities with high interest coupons will “call” (or prepay) their bonds before their maturity date. If an issuer exercised such a call during a period of declining interest rates, the Fund may have to replace such called security with a lower yielding security. If that were to happen, the Fund’s net investment income could fall.

Cash Transaction Risk. Most ETFs generally make in-kind redemptions to avoid being taxed on gains on the distributed portfolio securities at the fund level. However, unlike most ETFs, the Fund currently intends to effect creations and redemptions principally for cash, rather than principally in-kind, due to the nature of the Fund’s investments. As such, the Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. Therefore, the Fund may recognize a capital gain on these sales that might not have been incurred if the Fund had made a redemption in-kind. This may decrease the tax efficiency of the Fund compared to ETFs that utilize an in-kind redemption process and there may be a substantial difference in the after-tax rate of return between the Fund and conventional ETFs.

Changing U.S. Fixed-Income Market Conditions Risk. The current historically low interest rate environment was created in part by the Federal Reserve Board (“FRB”) keeping the federal funds rates at, near or below zero. The “tapering” in 2015 of the FRB’s quantitative easing program, combined with the FRB’s recent raising of the target range for the Federal Funds Rate may expose fixed-income markets to heightened volatility and reduced liquidity for certain fixed-income investments, particularly those with longer maturities, although it is difficult to predict the impact of this rate increase and any future rate increases on various markets. In addition, decreases in fixed-income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed-income markets. As a result, the value of the Fund’s investments and share price may decline. Changes in FRB policies could also result in higher than normal shareholder redemptions, which could potentially increase portfolio turnover rate and the Fund’s transaction costs.

Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security.

Index Rebalance Risk. Pursuant to the methodology that the Index Provider uses to maintain the Underlying Index, securities may be frequently added or removed from the Underlying Index during regular Underlying Index rebalances. As a result, to the extent the Fund attempts to replicate the Underlying Index, the Fund may frequently buy or sell securities, increasing portfolio turnover. Higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. Additionally, Underlying Index rebalances may cause the Fund to purchase or 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 these factors, the variation between the Fund’s annual return and the return of the Underlying Index may increase significantly.

Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Industry Concentration Risk. The Underlying Index from time to time may be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries or sectors. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or sector may be out of favor and underperform other industries or the market as a whole.

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

Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price.

Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV.

Non-Correlation Risk. The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. Because the Fund issues and redeems Creation Units principally for cash, it will incur higher costs in buying and selling securities than if it issued and redeemed Creation Units in-kind. Additionally, the Fund’s use of a representative sampling approach may cause the Fund not to be as well-correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversified Fund Risk. Because the Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.

Non-Investment Grade Securities Risk. Non-investment grade securities are considered speculative and unrated securities of comparable credit quality are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of the non-investment grade securities markets generally, real or perceived adverse economic and competitive industry conditions and less secondary market liquidity. If the issuer of non-investment grade securities defaults, the Fund may incur additional expenses to seek recovery.

Privately Issued Securities Risk. The Fund may invest in privately issued securities, including those that may be resold only in accordance with Rule 144A or Regulation S under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded, and Regulation S securities are securities of U.S. and non-U.S. issuers initially offered and sold outside the United States without registration with the SEC. Accordingly, the liquidity of the market for specific Rule 144A or Regulation S securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund.

Sampling Risk. The Fund’s use of a representative sampling approach will result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development to an issuer of securities that the Fund holds could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, Invesco Indexing LLC (the “Index Provider”) compiles and maintains the Underlying Index, which is designed to provide exposure to higher value, U.S. high yield bonds (commonly known as “junk bonds”). Higher value bonds are characterized as those with higher yields that may provide greater returns in certain markets. In addition, the Underlying Index seeks to incorporate securities with the highest “quality scores” (within the eligible universe of U.S. high yield bonds) as determined by the Index Provider using its methodology described below. The Index Provider is affiliated with Invesco Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”). In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by U.S. companies. To be eligible for inclusion in the Underlying Index, bonds must (i) be rated higher than B- and lower than BBB- (or equivalent) by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), Fitch Ratings Inc. (“Fitch”) or Moody’s Investors Service, Inc. (“Moody’s”) credit rating agencies; (ii) have at least $400 million outstanding, with only the largest bond from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Securities issued in accordance with Rule 144A (“Rule 144A securities”) under the Securities Act of 1933, as amended (“Securities Act”), bonds registered with the Securities and Exchange Commission (“SEC”), publicly underwritten medium-term notes and Eurodollar bonds are all eligible for inclusion in the Underlying Index. The Index Provider assigns a quality adjusted value score (“QAV Score”) to each eligible bond, which is calculated based on a combination of value and quality factors or characteristics. With respect to value, a value score (“Value Score”) is assigned to each eligible bond based on the bond’s option adjusted spread (“OAS”). Specifically, the Value Score for each bond is calculated as its percentile ranked OAS within its sector and credit rating category. With respect to credit category, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The bond is then assigned to one of six credit rating categories, as established by the Index Provider. Bonds are also separately ranked by OAS solely within their credit rating category. If fewer than three bonds are available within a sector or credit rating, then the Value Score for all bonds in the grouping is replaced with the percentile rank based on credit rating only. If fewer than three bonds are available within a credit rating category, then the bonds in that credit rating category are removed from Underlying Index eligibility. The Value Scores are then standardized. The Index Provider also calculates a quality score (“Quality Score”) for each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized across the universe of eligible bonds, and the Quality Score for each bond is computed as an equally-weighted combination of these two factors. Once a Value Score and Quality Score are assigned to eligible bonds, the QAV Score is calculated as a weighted-average combination of the two scores, with 90% and 10% weights applied to the Value Score and Quality Score, respectively. All eligible securities are ranked by the QAV Score. Initially, bonds with QAV Scores in the top 40% of eligible securities are selected for inclusion in the Underlying Index. At each monthly Underlying Index rebalance, any eligible security with a QAV Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index components with a QAV Score in the bottom 50% of eligible securities are removed. The Underlying Index will typically include between 100-300 securities, which are equally weighted. The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund utilizes a “sampling” methodology to seek to achieve its investment objective. The Fund is “non-diversified” and therefore is not required to meet certain diversification requirements under the Investment Company Act of 1940, as amended (the “1940 Act”). Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	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. Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs, and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that those APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities underlying the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with processing creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, which may be more likely to trade at a premium or discount to net asset value (“NAV”) and to face trading halts and/or delisting. This risk may be heightened for the Fund because it invests in non-U.S. securities, which may have lower trading volumes. Call Risk. If interest rates fall, it is possible that issuers of callable securities with high interest coupons will “call” (or prepay) their bonds before their maturity date. If an issuer exercised such a call during a period of declining interest rates, the Fund may have to replace such called security with a lower yielding security. If that were to happen, the Fund’s net investment income could fall. Cash Transaction Risk. Most ETFs generally make in-kind redemptions to avoid being taxed on gains on the distributed portfolio securities at the fund level. However, unlike most ETFs, the Fund currently intends to effect creations and redemptions principally for cash, rather than principally in-kind, due to the nature of the Fund’s investments. As such, the Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. Therefore, the Fund may recognize a capital gain on these sales that might not have been incurred if the Fund had made a redemption in-kind. This may decrease the tax efficiency of the Fund compared to ETFs that utilize an in-kind redemption process and there may be a substantial difference in the after-tax rate of return between the Fund and conventional ETFs. Changing U.S. Fixed-Income Market Conditions Risk. The current historically low interest rate environment was created in part by the Federal Reserve Board (“FRB”) keeping the federal funds rates at, near or below zero. The “tapering” in 2015 of the FRB’s quantitative easing program, combined with the FRB’s recent raising of the target range for the Federal Funds Rate may expose fixed-income markets to heightened volatility and reduced liquidity for certain fixed-income investments, particularly those with longer maturities, although it is difficult to predict the impact of this rate increase and any future rate increases on various markets. In addition, decreases in fixed-income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed-income markets. As a result, the value of the Fund’s investments and share price may decline. Changes in FRB policies could also result in higher than normal shareholder redemptions, which could potentially increase portfolio turnover rate and the Fund’s transaction costs. Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Index Rebalance Risk. Pursuant to the methodology that the Index Provider uses to maintain the Underlying Index, securities may be frequently added or removed from the Underlying Index during regular Underlying Index rebalances. As a result, to the extent the Fund attempts to replicate the Underlying Index, the Fund may frequently buy or sell securities, increasing portfolio turnover. Higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. Additionally, Underlying Index rebalances may cause the Fund to purchase or 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 these factors, the variation between the Fund’s annual return and the return of the Underlying Index may increase significantly. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Industry Concentration Risk. The Underlying Index from time to time may be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries or sectors. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or sector may be out of favor and underperform other industries or the market as a whole. Issuer-Specific Changes Risk. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk.

In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints. Non-Diversified Fund Risk. Because the Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance. Non-Investment Grade Securities Risk. Non-investment grade securities are considered speculative and unrated securities of comparable credit quality are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of the non-investment grade securities markets generally, real or perceived adverse economic and competitive industry conditions and less secondary market liquidity. If the issuer of non-investment grade securities defaults, the Fund may incur additional expenses to seek recovery. Privately Issued Securities Risk. The Fund may invest in privately issued securities, including those that may be resold only in accordance with Rule 144A or Regulation S under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded, and Regulation S securities are securities of U.S. and non-U.S. issuers initially offered and sold outside the United States without registration with the SEC. Accordingly, the liquidity of the market for specific Rule 144A or Regulation S securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund. Sampling Risk.

Invesco Investment Grade Defensive ETF

Invesco Investment Grade Defensive ETF

Summary Information

Investment Objective

The Invesco Investment Grade Defensive ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Invesco Investment Grade Defensive Index (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.

Annual Fund Operating Expenses

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:

Expense Example	1 Year	3 Years

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 will cause the Fund to incur additional 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 generally will invest at least 80% of its total assets in securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, Invesco Indexing LLC (the “Index Provider”) compiles and maintains the Underlying Index, which is designed to provide exposure to U.S. investment grade bonds having the highest “quality scores” (within the eligible universe of U.S. investment grade bonds) as determined by the Index Provider using its methodology described below. The Index Provider is affiliated with Invesco Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of all U.S. dollar denominated bonds issued by U.S. companies. To be eligible for inclusion in the Underlying Index, bonds must (i) be rated higher than BBB- (or equivalent) by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), Fitch Ratings Inc. (“Fitch”) or Moody’s Investors Service, Inc. (“Moody’s”) credit rating agencies; (ii) have at least $600 million outstanding, with only the largest bond from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Securities issued in accordance with Rule 144A (“Rule 144A securities”) under the Securities Act of 1933, as amended (“Securities Act”), bonds registered with the Securities and Exchange Commission (“SEC”), publicly underwritten medium-term notes and Eurodollar bonds are all eligible for inclusion in the Underlying Index.

The Index Provider assigns a quality score (“Quality Score”) to each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized across the universe of eligible bonds, and the Quality Score for each bond is computed as an equally-weighted combination of these two factors.

All eligible securities are ranked by Quality Score. Initially, bonds with Quality Scores in the top 40% of eligible securities are selected for inclusion in the Underlying Index. At each monthly Underlying Index rebalance, any eligible security with a Quality Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index components with a Quality Score in the bottom 50% of eligible securities are removed. The Underlying Index will typically include between 50-300 securities, which are equally weighted.

The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund utilizes a “sampling” methodology to seek to achieve its investment objective.

The Fund is “non-diversified” and therefore is not required to meet certain diversification requirements under the Investment Company Act of 1940, as amended (the “1940 Act”).

Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries. As of the date of this prospectus, a significant portion of the Underlying Index is represented by the financial sector and, accordingly, the Adviser anticipates that the Fund may concentrate its investments in that sector. The Fund’s portfolio holdings, and the extent to which it concentrates in any industry or group of industries, are likely to change over time.

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.

Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs, and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that those APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities underlying the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with processing creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, which may be more likely to trade at a premium or discount to net asset value (“NAV”) and to face trading halts and/or delisting. This risk may be heightened for the Fund because it invests in non-U.S. securities, which may have lower trading volumes.

Call Risk. If interest rates fall, it is possible that issuers of callable securities with high interest coupons will “call” (or prepay) their bonds before their maturity date. If an issuer exercised such a call during a period of declining interest rates, the Fund may have to replace such called security with a lower yielding security. If that were to happen, the Fund’s net investment income could fall.

Cash Transaction Risk. Most ETFs generally make in-kind redemptions to avoid being taxed on gains on the distributed portfolio securities at the fund level. However, unlike most ETFs, the Fund currently intends to effect creations and redemptions principally for cash, rather than principally in-kind, due to the nature of the Fund’s investments. As such, the Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. Therefore, the Fund may recognize a capital gain on these sales that might not have been incurred if the Fund had made a redemption in-kind. This may decrease the tax efficiency of the Fund compared to ETFs that utilize an in-kind redemption process and there may be a substantial difference in the after-tax rate of return between the Fund and conventional ETFs.

Changing U.S. Fixed-Income Market Conditions Risk. The current historically low interest rate environment was created in part by the Federal Reserve Board (“FRB”) keeping the federal funds rates at, near or below zero. The “tapering” in 2015 of the FRB’s quantitative easing program, combined with the FRB’s recent raising of the target range for the Federal Funds Rate may expose fixed-income markets to heightened volatility and reduced liquidity for certain fixed-income investments, particularly those with longer maturities, although it is difficult to predict the impact of this rate increase and any future rate increases on various markets. In addition, decreases in fixed-income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed-income markets. As a result, the value of the Fund’s investments and share price may decline. Changes in FRB policies could also result in higher than normal shareholder redemptions, which could potentially increase portfolio turnover rate and the Fund’s transaction costs.

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.

Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security.

Index Rebalance Risk. Pursuant to the methodology that the Index Provider uses to maintain the Underlying Index, securities may be frequently added or removed from the Underlying Index during regular Underlying Index rebalances. As a result, to the extent the Fund attempts to replicate the Underlying Index, the Fund may frequently buy or sell securities, increasing portfolio turnover. Higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. Additionally, Underlying Index rebalances may cause the Fund to purchase or 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 these factors, the variation between the Fund’s annual return and the return of the Underlying Index may increase significantly.

Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Industry Concentration Risk. The Underlying Index from time to time may be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries or sectors. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or sector may be out of favor and underperform other industries or the market as a whole.

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

Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price.

Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV.

Non-Correlation Risk. The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. Because the Fund issues and redeems Creation Units principally for cash, it will incur higher costs in buying and selling securities than if it issued and redeemed Creation Units in-kind. Additionally, the Fund’s use of a representative sampling approach may cause the Fund not to be as well-correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversified Fund Risk. Because the Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.

Privately Issued Securities Risk. The Fund may invest in privately issued securities, including those that may be resold only in accordance with Rule 144A or Regulation S under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded, and Regulation S securities are securities of U.S. and non-U.S. issuers initially offered and sold outside the United States without registration with the SEC. Accordingly, the liquidity of the market for specific Rule 144A securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund.

Sampling Risk. The Fund’s use of a representative sampling approach will result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development to an issuer of securities that the Fund holds could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, Invesco Indexing LLC (the “Index Provider”) compiles and maintains the Underlying Index, which is designed to provide exposure to U.S. investment grade bonds having the highest “quality scores” (within the eligible universe of U.S. investment grade bonds) as determined by the Index Provider using its methodology described below. The Index Provider is affiliated with Invesco Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”). In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of all U.S. dollar denominated bonds issued by U.S. companies. To be eligible for inclusion in the Underlying Index, bonds must (i) be rated higher than BBB- (or equivalent) by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), Fitch Ratings Inc. (“Fitch”) or Moody’s Investors Service, Inc. (“Moody’s”) credit rating agencies; (ii) have at least $600 million outstanding, with only the largest bond from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Securities issued in accordance with Rule 144A (“Rule 144A securities”) under the Securities Act of 1933, as amended (“Securities Act”), bonds registered with the Securities and Exchange Commission (“SEC”), publicly underwritten medium-term notes and Eurodollar bonds are all eligible for inclusion in the Underlying Index. The Index Provider assigns a quality score (“Quality Score”) to each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized across the universe of eligible bonds, and the Quality Score for each bond is computed as an equally-weighted combination of these two factors. All eligible securities are ranked by Quality Score. Initially, bonds with Quality Scores in the top 40% of eligible securities are selected for inclusion in the Underlying Index. At each monthly Underlying Index rebalance, any eligible security with a Quality Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index components with a Quality Score in the bottom 50% of eligible securities are removed. The Underlying Index will typically include between 50-300 securities, which are equally weighted. The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund utilizes a “sampling” methodology to seek to achieve its investment objective. The Fund is “non-diversified” and therefore is not required to meet certain diversification requirements under the Investment Company Act of 1940, as amended (the “1940 Act”). Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

Invesco Investment Grade Value ETF

Invesco Investment Grade Value ETF

Summary Information

Investment Objective

The Invesco Investment Grade Value ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Invesco Investment Grade Value Index (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.

Annual Fund Operating Expenses

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:

Expense Example	1 Year	3 Years

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 will cause the Fund to incur additional 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 generally will invest at least 80% of its total assets in securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, Invesco Indexing LLC (the “Index Provider”) compiles and maintains the Underlying Index, which is designed to provide exposure to higher value, U.S. investment grade bonds. Higher value bonds are characterized as those with higher yields that may provide greater returns in certain markets. In addition, the Underlying Index seeks to incorporate securities with the highest “quality scores” (within the eligible universe of U.S. investment grade bonds) as determined by the Index Provider using its methodology described below. The Index Provider is affiliated with Invesco Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of all U.S. dollar denominated bonds issued by U.S. companies. To be eligible for inclusion in the Underlying Index, bonds must (i) be rated higher than BBB- (or equivalent) by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), Fitch Ratings Inc. (“Fitch”) or Moody’s Investors Service, Inc. (“Moody’s”) credit rating agencies; (ii) have at least $600 million outstanding, with only the largest bond from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Securities issued in accordance with Rule 144A (“Rule 144A securities”) under the Securities Act of 1933, as amended (“Securities Act”), bonds registered with the Securities and Exchange Commission (“SEC”), publicly underwritten medium-term notes and Eurodollar bonds are all eligible for inclusion in the Underlying Index.

The Index Provider assigns a quality adjusted value score (“QAV Score”) to each eligible bond, which is calculated based on a combination of value and quality factors or characteristics. With respect to value, a value score (“Value Score”) is assigned to each eligible bond based on the bond’s option adjusted spread (“OAS”). Specifically, the Value Score for each bond is calculated as its percentile ranked OAS within its sector and credit rating category. With respect to credit category, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The bond is then assigned to one of six credit rating categories, as established by the Index Provider. Bonds are also separately ranked by OAS solely within their credit rating category. If fewer than three bonds are available within a sector or credit rating, then the Value Score for all bonds in the grouping is replaced with the percentile rank based on credit rating only. If fewer than three bonds are available within a credit rating category, then the bonds in that credit rating category are removed from Underlying Index eligibility. The Value Scores are then standardized.

The Index Provider also calculates a quality score (“Quality Score”) for each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized across the universe of eligible bonds, and the Quality Score for each bond is computed as an equally-weighted combination of these two factors.

Once a Value Score and Quality Score are assigned to eligible bonds, the QAV Score is calculated as a weighted-average combination of the two scores, with 90% and 10% weights applied to the Value Score and Quality Score, respectively.

All eligible securities are ranked by the QAV Score. Initially, bonds with QAV Scores in the top 40% of eligible securities are selected for inclusion in the Underlying Index. At each monthly Underlying Index rebalance, any eligible security with a QAV Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index components with a QAV Score in the bottom 50% of eligible securities are removed. The Underlying Index will typically include between 50-300 securities, which are equally weighted.

The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund utilizes a “sampling” methodology to seek to achieve its investment objective.

The Fund is “non-diversified” and therefore is not required to meet certain diversification requirements under the Investment Company Act of 1940, as amended (the “1940 Act”).

Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries. As of the date of this prospectus, a significant portion of the Underlying Index is represented by the financial sector and, accordingly, the Adviser anticipates that the Fund may concentrate its investments in that sector. The Fund’s portfolio holdings, and the extent to which it concentrates in any industry or group of industries, are likely to change over time.

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.

Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs, and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that those APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities underlying the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with processing creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, which may be more likely to trade at a premium or discount to net asset value (“NAV”) and to face trading halts and/or delisting. This risk may be heightened for the Fund because it invests in non-U.S. securities, which may have lower trading volumes.

Call Risk. If interest rates fall, it is possible that issuers of callable securities with high interest coupons will “call” (or prepay) their bonds before their maturity date. If an issuer exercised such a call during a period of declining interest rates, the Fund may have to replace such called security with a lower yielding security. If that were to happen, the Fund’s net investment income could fall.

Cash Transaction Risk. Most ETFs generally make in-kind redemptions to avoid being taxed on gains on the distributed portfolio securities at the fund level. However, unlike most ETFs, the Fund currently intends to effect creations and redemptions principally for cash, rather than principally in-kind, due to the nature of the Fund’s investments. As such, the Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. Therefore, the Fund may recognize a capital gain on these sales that might not have been incurred if the Fund had made a redemption in-kind. This may decrease the tax efficiency of the Fund compared to ETFs that utilize an in-kind redemption process and there may be a substantial difference in the after-tax rate of return between the Fund and conventional ETFs.

Changing U.S. Fixed-Income Market Conditions Risk. The current historically low interest rate environment was created in part by the Federal Reserve Board (“FRB”) keeping the federal funds rates at, near or below zero. The “tapering” in 2015 of the FRB’s quantitative easing program, combined with the FRB’s recent raising of the target range for the Federal Funds Rate may expose fixed-income markets to heightened volatility and reduced liquidity for certain fixed-income investments, particularly those with longer maturities, although it is difficult to predict the impact of this rate increase and any future rate increases on various markets. In addition, decreases in fixed-income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed-income markets. As a result, the value of the Fund’s investments and share price may decline. Changes in FRB policies could also result in higher than normal shareholder redemptions, which could potentially increase portfolio turnover rate and the Fund’s transaction costs.

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.

Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security.

Index Rebalance Risk. Pursuant to the methodology that the Index Provider uses to maintain the Underlying Index, securities may be frequently added or removed from the Underlying Index during regular Underlying Index rebalances. As a result, to the extent the Fund attempts to replicate the Underlying Index, the Fund may frequently buy or sell securities, increasing portfolio turnover. Higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. Additionally, Underlying Index rebalances may cause the Fund to purchase or 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 these factors, the variation between the Fund’s annual return and the return of the Underlying Index may increase significantly.

Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Industry Concentration Risk. The Underlying Index from time to time may be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries or sectors. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or sector may be out of favor and underperform other industries or the market as a whole.

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

Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price.

Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV.

Non-Correlation Risk. The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. Because the Fund issues and redeems Creation Units principally for cash, it will incur higher costs in buying and selling securities than if it issued and redeemed Creation Units in-kind. Additionally, the Fund’s use of a representative sampling approach may cause the Fund not to be as well-correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversified Fund Risk. Because the Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.

Privately Issued Securities Risk. The Fund may invest in privately issued securities, including those that may be resold only in accordance with Rule 144A or Regulation S under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded, and Regulation S securities are securities of U.S. and non-U.S. issuers initially offered and sold outside the United States without registration with the SEC. Accordingly, the liquidity of the market for specific Rule 144A or Regulation S securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund.

Sampling Risk. The Fund’s use of a representative sampling approach will result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development to an issuer of securities that the Fund holds could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund generally will invest at least 80% of its total assets in securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, Invesco Indexing LLC (the “Index Provider”) compiles and maintains the Underlying Index, which is designed to provide exposure to higher value, U.S. investment grade bonds. Higher value bonds are characterized as those with higher yields that may provide greater returns in certain markets. In addition, the Underlying Index seeks to incorporate securities with the highest “quality scores” (within the eligible universe of U.S. investment grade bonds) as determined by the Index Provider using its methodology described below. The Index Provider is affiliated with Invesco Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”). In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of all U.S. dollar denominated bonds issued by U.S. companies. To be eligible for inclusion in the Underlying Index, bonds must (i) be rated higher than BBB- (or equivalent) by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), Fitch Ratings Inc. (“Fitch”) or Moody’s Investors Service, Inc. (“Moody’s”) credit rating agencies; (ii) have at least $600 million outstanding, with only the largest bond from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Securities issued in accordance with Rule 144A (“Rule 144A securities”) under the Securities Act of 1933, as amended (“Securities Act”), bonds registered with the Securities and Exchange Commission (“SEC”), publicly underwritten medium-term notes and Eurodollar bonds are all eligible for inclusion in the Underlying Index. The Index Provider assigns a quality adjusted value score (“QAV Score”) to each eligible bond, which is calculated based on a combination of value and quality factors or characteristics. With respect to value, a value score (“Value Score”) is assigned to each eligible bond based on the bond’s option adjusted spread (“OAS”). Specifically, the Value Score for each bond is calculated as its percentile ranked OAS within its sector and credit rating category. With respect to credit category, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The bond is then assigned to one of six credit rating categories, as established by the Index Provider. Bonds are also separately ranked by OAS solely within their credit rating category. If fewer than three bonds are available within a sector or credit rating, then the Value Score for all bonds in the grouping is replaced with the percentile rank based on credit rating only. If fewer than three bonds are available within a credit rating category, then the bonds in that credit rating category are removed from Underlying Index eligibility. The Value Scores are then standardized. The Index Provider also calculates a quality score (“Quality Score”) for each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized across the universe of eligible bonds, and the Quality Score for each bond is computed as an equally-weighted combination of these two factors. Once a Value Score and Quality Score are assigned to eligible bonds, the QAV Score is calculated as a weighted-average combination of the two scores, with 90% and 10% weights applied to the Value Score and Quality Score, respectively. All eligible securities are ranked by the QAV Score. Initially, bonds with QAV Scores in the top 40% of eligible securities are selected for inclusion in the Underlying Index. At each monthly Underlying Index rebalance, any eligible security with a QAV Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index components with a QAV Score in the bottom 50% of eligible securities are removed.

The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund utilizes a “sampling” methodology to seek to achieve its investment objective. The Fund is “non-diversified” and therefore is not required to meet certain diversification requirements under the Investment Company Act of 1940, as amended (the “1940 Act”). Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

As a result, the value of the Fund’s investments and share price may decline. Changes in FRB policies could also result in higher than normal shareholder redemptions, which could potentially increase portfolio turnover rate and the Fund’s transaction costs. 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. Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down.

There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Index Rebalance Risk. Pursuant to the methodology that the Index Provider uses to maintain the Underlying Index, securities may be frequently added or removed from the Underlying Index during regular Underlying Index rebalances. As a result, to the extent the Fund attempts to replicate the Underlying Index, the Fund may frequently buy or sell securities, increasing portfolio turnover.

Additionally, Underlying Index rebalances may cause the Fund to purchase or 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 these factors, the variation between the Fund’s annual return and the return of the Underlying Index may increase significantly. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Industry Concentration Risk. The Underlying Index from time to time may be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or sector, the Fund will also concentrate its investments to approximately the same extent.

In addition, at times, such industry or sector may be out of favor and underperform other industries or the market as a whole. Issuer-Specific Changes Risk. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk.

This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance. Privately Issued Securities Risk. The Fund may invest in privately issued securities, including those that may be resold only in accordance with Rule 144A or Regulation S under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded, and Regulation S securities are securities of U.S. and non-U.S. issuers initially offered and sold outside the United States without registration with the SEC. Accordingly, the liquidity of the market for specific Rule 144A or Regulation S securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund. Sampling Risk. The Fund’s use of a representative sampling approach will result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development to an issuer of securities that the Fund holds could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater.

Invesco Multi-Factor Core Fixed Income ETF

Invesco Multi-Factor Core Fixed Income ETF

Summary Information

Investment Objective

The Invesco Multi-Factor Core Fixed Income ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Invesco Multi-Factor Core Index (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 will cause the Fund to incur additional 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 generally will invest at least 80% of its total assets in securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, Invesco Indexing LLC (the “Index Provider”) compiles and maintains the Underlying Index, which is designed to provide multi-factor exposure to fixed income securities. The Index Provider is affiliated with Invesco Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Underlying Index is an index of indexes, comprised of component securities of the following indexes (each, a “Sub-Index”), with corresponding fixed, target weightings in the Underlying Index: (i) Invesco U.S. Fixed Rate 30-Year MBS Index (40% weight); (ii) Invesco Investment Grade Defensive Index (25% weight); (iii) Invesco U.S. Treasury 1-3 Years Index (20% weight); (iv) Invesco U.S. Treasury 10-30 Years Index (10% weight); and (v) Invesco Investment Grade Value Index (5% weight). The Underlying Index will typically include between 400-1,000 securities. The securities in the Underlying Index are weighted in accordance with the methodology of each Sub-Index. Additional information about each Sub-Index is set forth below.

Invesco U.S. Fixed Rate 30-Year MBS Index. The Invesco U.S. Fixed Rate 30-Year MBS Index (the “MBS Index”) is designed to provide exposure to mortgage-backed pass-through securities of the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”). The MBS Index is compiled and maintained by the Index Provider.

In selecting components for inclusion in the MBS Index, the Index Provider begins with an investment universe of generic aggregates (“MBS Generics”), which are groups of pools of mortgage-backed securities (“MBS”) based on shared issuing agent, coupon rate and production year (i.e., the year that the mortgages were originated). The MBS Generics include pools of 30-year mortgages issued by Fannie Mae and Freddie Mac. They are based on fixed rate mortgages with at least one year remaining to maturity. The total amount outstanding of all production years for a given issuer and coupon must be at least $5 billion, and the total amount outstanding for a given coupon must be at least $250 million.

From the universe of MBS Generics, the MBS Index include all outstanding pools of 30-year mortgages issued by Fannie Mae and Freddie Mac that were produced in the past three years. The MBS Index rebalances monthly, at which time MBS Generics selected for inclusion in the MBS Index are market-value weighted.

Invesco Investment Grade Defensive Index. The Invesco Investment Grade Defensive Index (the “IG Defensive Index”) is designed to provide exposure to U.S. investment grade bonds having the highest “quality scores” (within the eligible universe of U.S. investment grade bonds) as determined by the Index Provider using its methodology described below. The IG Defensive Index is compiled and maintained by the Index Provider.

In selecting components for inclusion in the IG Defensive Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by U.S. companies. To be eligible for inclusion, bonds must (i) be rated higher than BBB- (or equivalent) by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), Fitch Ratings Inc. (“Fitch”) or Moody’s Investors Service, Inc. (“Moody’s”) credit rating agencies; (ii) have at least $600 million outstanding, with only the largest bond from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Securities issued in accordance with Rule 144A (“Rule 144A securities”) under the Securities Act of 1933, as amended (the “Securities Act”) bonds registered with the U.S. Securities and Exchange Commission (“SEC”), publicly underwritten medium-term notes and Eurodollar bonds are all eligible for inclusion in the IG Defensive Index.

The Index Provider assigns a quality score (“Quality Score”) to each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized across the universe of eligible bonds, and the Quality Score for each bond is computed as an equally-weighted combination of these two factors.

All eligible securities are ranked by Quality Score. Initially, bonds with Quality Scores in the top 40% of eligible securities are selected for inclusion in the IG Defensive Index. At each monthly IG Defensive Index rebalance, any eligible security with a Quality Score in the top 30% of eligible securities is added to the IG Defensive Index, and current components with a Quality Score in the bottom 50% of eligible securities are removed. IG Defensive Index components are equally weighted.

Invesco U.S. Treasury 1-3 Years Index. The Invesco U.S. Treasury 1-3 Years Index (the “Treasury 1-3 Years Index”) is compiled and maintained by the Index Provider and includes U.S dollar-denominated Treasury securities with a maturity from one year up to three years, regardless of call features. To be eligible for inclusion, the securities must also have at least $1 billion par amount outstanding. The securities included in the Treasury 1-3 Years Index are market-value weighted.

Invesco U.S. Treasury 10-30 Years Index. The Invesco U.S. Treasury 10-30 Years Index (the “Treasury 10-30 Years Index”) is compiled and maintained by the Index Provider and includes U.S dollar-denominated Treasury securities with a maturity from ten years up to thirty years, regardless of call features. To be eligible for inclusion, the securities must also have at least $1 billion par amount outstanding. The securities included in the Treasury 10-30 Years Index are market-value weighted.

Invesco Investment Grade Value Index. The Invesco Investment Grade Value Index (the “IG Value Index”) is designed to provide exposure to higher value, U.S. investment grade bonds. Higher value bonds are characterized as those with higher yields that may provide greater returns in certain markets. In addition, the IG Value seeks to incorporate securities with the highest “quality scores” (within the eligible universe of U.S. investment grade bonds) as determined by the Index Provider using its methodology described below. The IG Value Index is compiled and maintained by the Index Provider.

In selecting components for inclusion in the IG Value Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by U.S. companies. To be eligible for inclusion, bonds must (i) be rated higher than BBB- (or equivalent) by S&P, Fitch, or Moody’s credit rating agencies; (ii) have at least $600 million outstanding, with only the largest bond from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Rule 144A securities, bonds registered with the SEC, publicly underwritten medium-term notes and Eurodollar bonds are all eligible for inclusion in the IG Value Index.

The Index Provider assigns a QAV Score to each eligible bond, which is calculated based on a combination of value and quality factors or characteristics. With respect to value, a value score (“Value Score”) is assigned to each eligible bond based on the bond’s option adjusted spread (“OAS”). Specifically, the Value Score for each bond is calculated as its percentile ranked OAS within its sector and credit rating category. With respect to credit category, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The bond is then assigned to one of six credit rating categories, as established by the Index Provider. Bonds are also separately ranked by OAS solely within their credit rating category. If fewer than three bonds are available within a sector or credit rating, then the Value Score for all bonds in the grouping is replaced with the percentile rank based on credit rating only. If fewer than three bonds are available within a rating category, then the bonds in that rating category are removed from IG Value Index eligibility. The Value Scores are then standardized.

The Index Provider also calculates a quality score (“Quality Score”) for each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized across the universe of eligible bonds, and the Quality Score for each bond is computed as an equally-weighted combination of these two factors.

Once a Value Score and Quality Score are assigned to eligible bonds, the QAV Score is calculated as a weighted average combination of the two scores, with 90% and 10% weights applied to the Value Score and Quality Score, respectively.

All eligible securities are ranked by the QAV Score. Initially, bonds with QAV Scores in the top 40% of eligible securities are selected for inclusion in the IG Value Index. At each monthly IG Value Index rebalance, any eligible security with a QAV Score in the top 30% of eligible securities is added to the IG Value Index, and current IG Value Index components with a QAV Score in the bottom 50% of eligible securities are removed. IG Value Index components are equally weighted.

The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund utilizes a “sampling” methodology to seek to achieve its investment objective.

The Fund is “non-diversified” and therefore is not required to meet certain diversification requirements under the Investment Company Act of 1940, as amended (the “1940 Act”).

Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

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.

Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs, and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that those APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities underlying the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with processing creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, which may be more likely to trade at a premium or discount to net asset value (“NAV”) and to face trading halts and/or delisting. This risk may be heightened for the Fund because it invests in non-U.S. securities, which may have lower trading volumes.

Call Risk. If interest rates fall, it is possible that issuers of callable securities with high interest coupons will “call” (or prepay) their bonds before their maturity date. If an issuer exercised such a call during a period of declining interest rates, the Fund may have to replace such called security with a lower yielding security. If that were to happen, the Fund’s net investment income could fall.

Cash Transaction Risk. Most ETFs generally make in-kind redemptions to avoid being taxed on gains on the distributed portfolio securities at the fund level. However, unlike most ETFs, the Fund currently intends to effect creations and redemptions principally for cash, rather than principally in-kind, due to the nature of the Fund’s investments. As such, the Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. Therefore, the Fund may recognize a capital gain on these sales that might not have been incurred if the Fund had made a redemption in-kind. This may decrease the tax efficiency of the Fund compared to ETFs that utilize an in-kind redemption process and there may be a substantial difference in the after-tax rate of return between the Fund and conventional ETFs.

Changing U.S. Fixed-Income Market Conditions Risk. The current historically low interest rate environment was created in part by the Federal Reserve Board (“FRB”) keeping the federal funds rates at, near or below zero. The “tapering” in 2015 of the FRB’s quantitative easing program, combined with the FRB’s recent raising of the target range for the Federal Funds Rate may expose fixed-income markets to heightened volatility and reduced liquidity for certain fixed-income investments, particularly those with longer maturities, although it is difficult to predict the impact of this rate increase and any future rate increases on various markets. In addition, decreases in fixed-income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed-income markets. As a result, the value of the Fund’s investments and share price may decline. Changes in FRB policies could also result in higher than normal shareholder redemptions, which could potentially increase portfolio turnover rate and the Fund’s transaction costs.

Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security.

Index Rebalance Risk. Pursuant to the methodology that the Index Provider uses to maintain the Underlying Index, securities may be frequently added or removed from the Underlying Index during regular Underlying Index rebalances. As a result, to the extent the Fund attempts to replicate the Underlying Index, the Fund may frequently buy or sell securities, increasing portfolio turnover. Higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. Additionally, Underlying Index rebalances may cause the Fund to purchase or 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 these factors, the variation between the Fund’s annual return and the return of the Underlying Index may increase significantly.

Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Industry Concentration Risk. The Underlying Index from time to time may be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries or sectors. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or sector may be out of favor and underperform other industries or the market as a whole.

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

Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price.

Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV.

Mortgage-Backed Securities Risk. Investments in mortgage-backed securities are subject to prepayment or call risk, which is the risk that payments from the borrower may be received earlier than expected due to changes in the rate at which the underlying loans are prepaid. Securities may be prepaid at a price less than the original purchase value.

Non-Correlation Risk. The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. Because the Fund issues and redeems Creation Units principally for cash, it will incur higher costs in buying and selling securities than if it issued and redeemed Creation Units in-kind. Additionally, the Fund’s use of a representative sampling approach may cause the Fund not to be as well-correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversified Fund Risk. Because the Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.

Privately Issued Securities Risk. The Fund may invest in privately issued securities, including those that may be resold only in accordance with Rule 144A or Regulation S under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded, and Regulation S securities are securities of U.S. and non-U.S. issuers initially offered and sold outside the United States without registration with the SEC. Accordingly, the liquidity of the market for specific Rule 144A or Regulation S securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund.

Sampling Risk. The Fund’s use of a representative sampling approach will result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development to an issuer of securities that the Fund holds could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater.

U.S. Government Obligation Risk. The Fund may invest in U.S. government obligations issued or guaranteed by the U.S. Government, its agencies and instrumentalities, including bills, notes and bonds issued by the U.S. Treasury. U.S. Government securities include securities that are issued or guaranteed by the United States Treasury, by various agencies of the U.S. Government, or by various instrumentalities which have been established or sponsored by the U.S. Government. U.S. Treasury securities are backed by the “full faith and credit” of the United States. Securities issued or guaranteed by federal agencies and U.S. Government-sponsored instrumentalities may or may not be backed by the full faith and credit of the United States. In the case of those U.S. Government securities not backed by the full faith and credit of the United States, the investor must look principally to the agency or instrumentality issuing or guaranteeing the security for ultimate repayment, and may not be able to assert a claim against the United States itself in the event that the agency or instrumentality does not meet its commitment. The U.S. Government, its agencies and instrumentalities do not guarantee the market value of their securities, and consequently, the value of such securities may fluctuate.

The Invesco U.S. Treasury 10-30 Years Index (the “Treasury 10-30 Years Index”) is compiled and maintained by the Index Provider and includes U.S dollar-denominated Treasury securities with a maturity from ten years up to thirty years, regardless of call features. To be eligible for inclusion, the securities must also have at least $1 billion par amount outstanding. The securities included in the Treasury 10-30 Years Index are market-value weighted. Invesco Investment Grade Value Index. The Invesco Investment Grade Value Index (the “IG Value Index”) is designed to provide exposure to higher value, U.S. investment grade bonds. Higher value bonds are characterized as those with higher yields that may provide greater returns in certain markets. In addition, the IG Value seeks to incorporate securities with the highest “quality scores” (within the eligible universe of U.S. investment grade bonds) as determined by the Index Provider using its methodology described below. The IG Value Index is compiled and maintained by the Index Provider. In selecting components for inclusion in the IG Value Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by U.S. companies. To be eligible for inclusion, bonds must (i) be rated higher than BBB- (or equivalent) by S&P, Fitch, or Moody’s credit rating agencies; (ii) have at least $600 million outstanding, with only the largest bond from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Rule 144A securities, bonds registered with the SEC, publicly underwritten medium-term notes and Eurodollar bonds are all eligible for inclusion in the IG Value Index. The Index Provider assigns a QAV Score to each eligible bond, which is calculated based on a combination of value and quality factors or characteristics. With respect to value, a value score (“Value Score”) is assigned to each eligible bond based on the bond’s option adjusted spread (“OAS”). Specifically, the Value Score for each bond is calculated as its percentile ranked OAS within its sector and credit rating category. With respect to credit category, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The bond is then assigned to one of six credit rating categories, as established by the Index Provider. Bonds are also separately ranked by OAS solely within their credit rating category. If fewer than three bonds are available within a sector or credit rating, then the Value Score for all bonds in the grouping is replaced with the percentile rank based on credit rating only. If fewer than three bonds are available within a rating category, then the bonds in that rating category are removed from IG Value Index eligibility. The Value Scores are then standardized. The Index Provider also calculates a quality score (“Quality Score”) for each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized across the universe of eligible bonds, and the Quality Score for each bond is computed as an equally-weighted combination of these two factors. Once a Value Score and Quality Score are assigned to eligible bonds, the QAV Score is calculated as a weighted average combination of the two scores, with 90% and 10% weights applied to the Value Score and Quality Score, respectively. All eligible securities are ranked by the QAV Score. Initially, bonds with QAV Scores in the top 40% of eligible securities are selected for inclusion in the IG Value Index. At each monthly IG Value Index rebalance, any eligible security with a QAV Score in the top 30% of eligible securities is added to the IG Value Index, and current IG Value Index components with a QAV Score in the bottom 50% of eligible securities are removed. IG Value Index components are equally weighted. The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund utilizes a “sampling” methodology to seek to achieve its investment objective. The Fund is “non-diversified” and therefore is not required to meet certain diversification requirements under the Investment Company Act of 1940, as amended (the “1940 Act”). Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	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. Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs, and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that those APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities underlying the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with processing creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, which may be more likely to trade at a premium or discount to net asset value (“NAV”) and to face trading halts and/or delisting. This risk may be heightened for the Fund because it invests in non-U.S. securities, which may have lower trading volumes. Call Risk. If interest rates fall, it is possible that issuers of callable securities with high interest coupons will “call” (or prepay) their bonds before their maturity date. If an issuer exercised such a call during a period of declining interest rates, the Fund may have to replace such called security with a lower yielding security. If that were to happen, the Fund’s net investment income could fall. Cash Transaction Risk. Most ETFs generally make in-kind redemptions to avoid being taxed on gains on the distributed portfolio securities at the fund level. However, unlike most ETFs, the Fund currently intends to effect creations and redemptions principally for cash, rather than principally in-kind, due to the nature of the Fund’s investments. As such, the Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. Therefore, the Fund may recognize a capital gain on these sales that might not have been incurred if the Fund had made a redemption in-kind. This may decrease the tax efficiency of the Fund compared to ETFs that utilize an in-kind redemption process and there may be a substantial difference in the after-tax rate of return between the Fund and conventional ETFs. Changing U.S. Fixed-Income Market Conditions Risk. The current historically low interest rate environment was created in part by the Federal Reserve Board (“FRB”) keeping the federal funds rates at, near or below zero. The “tapering” in 2015 of the FRB’s quantitative easing program, combined with the FRB’s recent raising of the target range for the Federal Funds Rate may expose fixed-income markets to heightened volatility and reduced liquidity for certain fixed-income investments, particularly those with longer maturities, although it is difficult to predict the impact of this rate increase and any future rate increases on various markets. In addition, decreases in fixed-income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed-income markets. As a result, the value of the Fund’s investments and share price may decline. Changes in FRB policies could also result in higher than normal shareholder redemptions, which could potentially increase portfolio turnover rate and the Fund’s transaction costs. Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Index Rebalance Risk. Pursuant to the methodology that the Index Provider uses to maintain the Underlying Index, securities may be frequently added or removed from the Underlying Index during regular Underlying Index rebalances. As a result, to the extent the Fund attempts to replicate the Underlying Index, the Fund may frequently buy or sell securities, increasing portfolio turnover. Higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. Additionally, Underlying Index rebalances may cause the Fund to purchase or 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 these factors, the variation between the Fund’s annual return and the return of the Underlying Index may increase significantly. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Industry Concentration Risk. The Underlying Index from time to time may be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries or sectors. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or sector may be out of favor and underperform other industries or the market as a whole. Issuer-Specific Changes Risk. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV. Mortgage-Backed Securities Risk. Investments in mortgage-backed securities are subject to prepayment or call risk, which is the risk that payments from the borrower may be received earlier than expected due to changes in the rate at which the underlying loans are prepaid. Securities may be prepaid at a price less than the original purchase value. Non-Correlation Risk. The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. Because the Fund issues and redeems Creation Units principally for cash, it will incur higher costs in buying and selling securities than if it issued and redeemed Creation Units in-kind. Additionally, the Fund’s use of a representative sampling approach may cause the Fund not to be as well-correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints. Non-Diversified Fund Risk. Because the Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance. Privately Issued Securities Risk. The Fund may invest in privately issued securities, including those that may be resold only in accordance with Rule 144A or Regulation S under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded, and Regulation S securities are securities of U.S. and non-U.S. issuers initially offered and sold outside the United States without registration with the SEC. Accordingly, the liquidity of the market for specific Rule 144A or Regulation S securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund. Sampling Risk. The Fund’s use of a representative sampling approach will result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development to an issuer of securities that the Fund holds could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater. U.S. Government Obligation Risk. The Fund may invest in U.S. government obligations issued or guaranteed by the U.S. Government, its agencies and instrumentalities, including bills, notes and bonds issued by the U.S. Treasury. U.S. Government securities include securities that are issued or guaranteed by the United States Treasury, by various agencies of the U.S. Government, or by various instrumentalities which have been established or sponsored by the U.S. Government. U.S. Treasury securities are backed by the “full faith and credit” of the United States. Securities issued or guaranteed by federal agencies and U.S. Government-sponsored instrumentalities may or may not be backed by the full faith and credit of the United States. In the case of those U.S. Government securities not backed by the full faith and credit of the United States, the investor must look principally to the agency or instrumentality issuing or guaranteeing the security for ultimate repayment, and may not be able to assert a claim against the United States itself in the event that the agency or instrumentality does not meet its commitment. The U.S. Government, its agencies and instrumentalities do not guarantee the market value of their securities, and consequently, the value of such securities may fluctuate.
Risk Lose Money [Text]	rr_RiskLoseMoney	The Shares will change in value, and you could lose money by investing in the Fund.
Risk Nondiversified Status [Text]	rr_RiskNondiversifiedStatus	Non-Diversified Fund Risk. Because the Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.

Invesco Multi-Factor Core Plus Fixed Income ETF

Invesco Multi-Factor Core Plus Fixed Income ETF

Summary Information

Investment Objective

The Invesco Multi-Factor Core Plus Fixed Income ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Invesco Multi-Factor Core Plus Index (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.

Annual Fund Operating Expenses
(expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	Invesco Multi-Factor Core Plus Fixed Income ETF Invesco Multi-Factor Core Plus fixed Income ETF
Management Fees	0.16%
Other Expenses	none	[1]
Total Annual Fund Operating Expenses	0.16%

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:

Expense Example	1 Year	3 Years

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 will cause the Fund to incur additional 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 generally will invest at least 80% of its total assets in securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, Invesco Indexing LLC (the “Index Provider”) compiles and maintains the Underlying Index, which is designed to provide multi-factor exposure to fixed income securities. The Index Provider is affiliated with Invesco Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).

The Underlying Index is an index of indexes, comprised of component securities of the following indexes (each, a “Sub-Index”), with corresponding fixed, target weightings in the Underlying Index: (i) Invesco High Yield Defensive Index (30% weight); (ii) Invesco Investment Grade Defensive Index (20% weight); (iii) Invesco U.S. Fixed Rate 30-Year MBS Index (20% weight); (iv) Invesco Investment Grade Value Index (10% weight); (v) Invesco U.S. Treasury 10-30 Years Index (10% weight); (vi) Invesco Emerging Markets Debt Defensive Index (5% weight); and (vii) Invesco Emerging Markets Debt Value Index (5% weight). The Underlying Index will typically include between 500-1,000 securities. The securities in the Underlying Index are weighted in accordance with the methodology of each Sub-Index. Additional information about each Sub-Index is set forth below.

Invesco High Yield Defensive Index. The Invesco High Yield Defensive Index (the “HY Defensive Index”) is designed to provide exposure to U.S. high yield bonds (commonly known as “junk bonds”) having the highest “quality scores” (within the eligible universe of U.S. high yield bonds) as determined by the Index Provider using its methodology described below.. The HY Defensive Index is compiled and maintained by the Index Provider.

In selecting components for inclusion in the HY Defensive Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by U.S. companies. To be eligible for inclusion in the HY Defensive Index, bonds must (i) be rated higher than B- and lower than BBB- (or equivalent) by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), Fitch Ratings Inc. (“Fitch”) or Moody’s Investors Service, Inc. (“Moody’s”) credit rating agencies; (ii) have at least $400 million outstanding, with only the largest bond from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Securities issued in accordance with Rule 144A (“Rule 144A securities”) under the Securities Act of 1933, as amended (the “Securities Act”) bonds registered with the Securities and Exchange Commission (“SEC”), publicly underwritten medium-term notes and Eurodollar bonds are all eligible for inclusion in the HY Defensive Index.

The Index Provider assigns a quality score (“Quality Score”) to each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized across the universe of eligible bonds, and the Quality Score for each bond is computed as an equally-weighted combination of these two factors.

All eligible securities are ranked by Quality Score. Initially, bonds with Quality Scores in the top 40% of eligible securities are selected for inclusion in the HY Defensive Index. At each monthly HY Defensive Index rebalance, any eligible security with a Quality Score in the top 30% of eligible securities is added to the HY Defensive Index, and current HY Defensive Index components with a Quality Score in the bottom 50% of eligible securities are removed. HY Defensive Index components are equally weighted.

Invesco Investment Grade Defensive Index. The Invesco Investment Grade Defensive Index (the “IG Defensive Index”) is designed to provide exposure to U.S. investment grade bonds having the highest “quality scores” (within the eligible universe of U.S. investment grade bonds) as determined by the Index Provider using its methodology described below. The IG Defensive Index is compiled and maintained by the Index Provider.

In selecting components for inclusion in the IG Defensive Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by U.S. companies. To be eligible for inclusion, bonds must (i) be rated higher than BBB- (or equivalent) by S&P, Fitch, or Moody’s credit rating agencies; (ii) have at least $600 million outstanding, with only the largest bond from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Rule 144A securities, bonds registered with the SEC, publicly underwritten medium-term notes and Eurodollar bonds are all eligible for inclusion in the IG Defensive Index.

The Index Provider assigns a quality score (“Quality Score”) to each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized across the universe of eligible bonds, and the Quality Score for each bond is computed as an equally-weighted combination of these two factors.

All eligible securities are ranked by Quality Score. Initially, bonds with Quality Scores in the top 40% of eligible securities are selected for inclusion in the IG Defensive Index. At each monthly IG Defensive Index rebalance, any eligible security with a Quality Score in the top 30% of eligible securities is added to the IG Defensive Index, and current components with a Quality Score in the bottom 50% of eligible securities are removed. IG Defensive Index components are equally weighted.

Invesco U.S. Fixed Rate 30-Year MBS Index. The Invesco U.S. Fixed Rate 30-Year MBS Index (the “MBS Index”) is designed to provide exposure to mortgage-backed pass through securities of the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”). The MBS Index is compiled and maintained by the Index Provider.

In selecting components for inclusion in the MBS Index, the Index Provider begins with an investment universe of generic aggregates (“MBS Generics”), which are groups of pools of mortgage-backed securities (“MBS”) based on shared issuing agent, coupon rate and production year (i.e., the year that the mortgages were originated). The MBS Generics include pools of 30-year mortgages issued by Fannie Mae and Freddie Mac. They are based on fixed rate mortgages with at least one year remaining to maturity. The total amount outstanding of all production years for a given issuer and coupon must be at least $5 billion, and the total amount outstanding for a given coupon must be at least $250 million.

From the universe of MBS Generics, the MBS Index include all outstanding pools of 30-year mortgages issued by Fannie Mae and Freddie Mac that were produced in the past three years. The MBS Index rebalances monthly, at which time the MBS Generics selected for inclusion in the MBS Index are market-value weighted.

Invesco Investment Grade Value Index. The Invesco Investment Grade Value Index (the “IG Value Index”) is designed to provide exposure to higher value, U.S. investment grade bonds. Higher value bonds are characterized as those with higher yields that may provide greater returns in certain markets. In addition, the IG Value seeks to incorporate securities with the highest “quality scores” (within the eligible universe of U.S. investment grade bonds) as determined by the Index Provider using its methodology described below. The IG Value Index is compiled and maintained by the Index Provider.

In selecting components for inclusion in the IG Value Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by U.S. companies. To be eligible for inclusion, bonds must (i) be rated higher than BBB- (or equivalent) by S&P, Fitch, or Moody’s credit rating agencies; (ii) have at least $600 million outstanding, with only the largest bond from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Rule 144A securities, bonds registered with the SEC, publicly underwritten medium-term notes and Eurodollar bonds are all eligible for inclusion in the IG Value Index.

The Index Provider assigns a QAV Score to each eligible bond, which is calculated based on a combination of value and quality factors or characteristics. With respect to value, a value score (“Value Score”) is assigned to each eligible bond based on the bond’s option adjusted spread (“OAS”). Specifically, the Value Score for each bond is calculated as its percentile ranked OAS within its sector and credit rating category. With respect to credit category, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The bond is then assigned to one of six credit rating categories, as established by the Index Provider. Bonds are also separately ranked by OAS solely within their credit rating category. If fewer than three bonds are available within a sector or credit rating, then the Value Score for all bonds in the grouping is replaced with the percentile rank based on credit rating only. If fewer than three bonds are available within a rating category, then the bonds in that rating category are removed from IG Value Index eligibility. The Value Scores are then standardized.

The Index Provider also calculates a quality score (“Quality Score”) for each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized across the universe of eligible bonds, and the Quality Score for each bond is computed as an equally-weighted combination of these two factors.

Once a Value Score and Quality Score are assigned to eligible bonds, the QAV Score is calculated as a weighted average combination of the two scores, with 90% and 10% weights applied to the Value Score and Quality Score, respectively.

All eligible securities are ranked by the QAV Score. Initially, bonds with QAV Scores in the top 40% of eligible securities are selected for inclusion in the IG Value Index. At each monthly IG Value Index rebalance, any eligible security with a QAV Score in the top 30% of eligible securities is added to the IG Value Index, and current IG Value Index components with a QAV Score in the bottom 50% of eligible securities are removed. IG Value Index components are equally weighted.

Invesco U.S. Treasury 10-30 Years Index. The Invesco U.S. Treasury 10-30 Years Index (the “Treasury 10-30 Years Index”) is compiled and maintained by the Index Provider and includes U.S dollar-denominated Treasury securities with a maturity from ten years up to thirty years, regardless of call features. To be eligible for inclusion, the securities must also have at least $1 billion par amount outstanding. The securities included in the Treasury 10-30 Years Index are market-value weighted.

Invesco Emerging Markets Debt Defensive Index. The Invesco Emerging Markets Debt Defensive Index (the “EM Debt Defensive Index”) designed to provide exposure to emerging markets debt securities having the highest “quality scores” (within the eligible universe of emerging market debt securities) as determined by the Index Provider using its methodology described below. The EM Debt Defensive Index is compiled and maintained by the Index Provider.

In selecting components for inclusion in the EM Debt Defensive Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by sovereign governments, and agencies thereof, of countries that that the Index Provider considers to be “emerging market countries” (as of June 15, 2018, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, Israel, Malaysia, Mexico, Morocco, Peru, the Philippines, Poland, Russia, South Africa, Taiwan, Thailand, Turkey, the United Arab Emirates and Vietnam). To be eligible for inclusion in the EM Debt Defensive Index, bonds must (i) be rated higher than B- (or equivalent) by S&P, Fitch or Moody’s credit rating agencies; (ii) have at least $500 million outstanding, with only the largest five bonds from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Rule 144A securities, securities issued in accordance with Regulation S under the Securities Act (“Regulation S securities”) and bonds registered with the SEC are all eligible for inclusion in the EM Debt Defensive Index.

The Index Provider assigns a quality score (“Quality Score”) to each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized by bond type (agency or sovereign), and the Quality Score for each bond is computed as a weighted-average combination of these two factors, with weights of 75% and 25% for maturity and credit rating, respectively.

All eligible securities are ranked by Quality Score. Initially, bonds with quality scores in the top 40% of eligible securities are selected for inclusion in the EM Debt Defensive Index. At each monthly EM Debt Defensive Index rebalance, any eligible security with a Quality Score in the top 30% of eligible securities is added to the EM Debt Defensive Index, and current components with a Quality Score in the bottom 40% of eligible securities are removed. EM Debt Defensive Index components are modified market-value weighted.

Invesco Emerging Markets Debt Value Index. The Invesco Emerging Markets Debt Value Index (the “EM Debt Value Index”) designed to provide exposure to higher value, emerging markets debt securities. Higher value bonds are characterized as those with higher yields that may provide greater returns in certain markets. In addition, the EM Debt Value Index seeks to incorporate securities with the highest “quality scores” (within the eligible universe of emerging market debt securities) as determined by the Index Provider using its methodology described below. The EM Debt Value Index is compiled and maintained by the Index Provider.

In selecting components for inclusion in the EM Debt Value Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by sovereign governments, and agencies thereof, of countries that that the Index Provider considers to be “emerging market countries” (as of June 15, 2018, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, Israel, Malaysia, Mexico, Morocco, Peru, the Philippines, Poland, Russia, South Africa, Taiwan, Thailand, Turkey, the United Arab Emirates and Vietnam). To be eligible for inclusion in the EM Debt Value Index, bonds must (i) be rated higher than B- (or equivalent) by S&P, Fitch or Moody’s credit rating agencies; (ii) have at least $500 million outstanding, with only the largest five bonds from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Rule 144A securities, Regulation S securities, and bonds registered with the SEC are all eligible for inclusion in the EM Debt Value Index.

The Index Provider assigns a quality adjusted value score (“QAV Score”) to each eligible bond, which is calculated based on a combination of value and quality factors or characteristics. With respect to value, a value score (“Value Score”) is assigned to each eligible bond based on the bond’s option adjusted spread (“OAS”). Specifically, the Value Score for each bond is calculated as its percentile ranked OAS within its bond type (agency or sovereign), region and credit rating category. With respect to credit category, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The bond is then assigned to one of six credit rating categories, as established by the Index Provider. Bonds are also separately ranked by OAS solely within their bond type category. If fewer than three bonds are available within a bond type, region or credit rating, then the Value Score for all bonds in the grouping is replaced with the percentile rank based on credit rating only. The Value Scores are then standardized.

The Index Provider also calculates a quality score (“Quality Score”) for each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized by bond type (agency or sovereign), and the Quality Score for each bond is computed as a weighted-average combination of these two factors, with weights of 75% and 25% for maturity and credit rating, respectively.

Once a Value Score and Quality Score are assigned to eligible bonds, the QAV Score is calculated as a weighted-average combination of the two scores, with 90% and 10% weights applied to the Value Score and Quality Score, respectively.

All eligible securities are ranked by the QAV Score. Initially, bonds with QAV Scores in the top 40% of eligible securities are selected for inclusion in the EM Debt Value Index. At each monthly EM Debt Value Index rebalance, any eligible security with a QAV Score in the top 30% of eligible securities is added to the EM Debt Value Index, and current EM Debt Value Index components with a QAV Score in the bottom 40% of eligible securities are removed. EM Debt Value Index components are modified market-value weighted.

The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund utilizes a “sampling” methodology to seek to achieve its investment objective.

The Fund is “non-diversified” and therefore is not required to meet certain diversification requirements under the Investment Company Act of 1940, as amended (the “1940 Act”).

Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries. As of the date of this prospectus, a significant portion of the Underlying Index is represented by the financial sector and, accordingly, the Adviser anticipates that the Fund may concentrate its investments in that sector. The Fund’s portfolio holdings, and the extent to which it concentrates in any industry or group of industries, are likely to change over time.

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.

Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs, and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that those APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities underlying the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with processing creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, which may be more likely to trade at a premium or discount to net asset value (“NAV”) and to face trading halts and/or delisting. This risk may be heightened for the Fund because it invests in non-U.S. securities, which may have lower trading volumes.

Call Risk. If interest rates fall, it is possible that issuers of callable securities with high interest coupons will “call” (or prepay) their bonds before their maturity date. If an issuer exercised such a call during a period of declining interest rates, the Fund may have to replace such called security with a lower yielding security. If that were to happen, the Fund’s net investment income could fall.

Cash Transaction Risk. Most ETFs generally make in-kind redemptions to avoid being taxed on gains on the distributed portfolio securities at the fund level. However, unlike most ETFs, the Fund currently intends to effect creations and redemptions principally for cash, rather than principally in-kind, due to the nature of the Fund’s investments. As such, the Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. Therefore, the Fund may recognize a capital gain on these sales that might not have been incurred if the Fund had made a redemption in-kind. This may decrease the tax efficiency of the Fund compared to ETFs that utilize an in-kind redemption process and there may be a substantial difference in the after-tax rate of return between the Fund and conventional ETFs.

Changing Global Fixed-Income Market Conditions Risk. The current historically low interest rate environment was created in part by the Federal Reserve Board (“FRB”) and certain foreign central banks keeping the federal funds and equivalent foreign rates at, near or below zero. The “tapering” in 2015 of the FRB’s quantitative easing program, combined with the FRB’s recent raising of the target range for the Federal Funds Rate (and continued possible fluctuations in equivalent foreign rates) may expose fixed-income markets to heightened volatility and reduced liquidity for certain fixed-income investments, particularly those with longer maturities, although it is difficult to predict the impact of this rate increase and any future rate increases on various markets. In addition, decreases in fixed-income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed-income markets. As a result, the value of the Fund’s investments and share price may decline. Changes in central bank policies could also result in higher than normal shareholder redemptions, which could potentially increase portfolio turnover rate and the Fund’s transaction costs.

Emerging Markets Sovereign Debt Risk. Government obligors in emerging market countries are among the world’s largest debtors to commercial banks, other governments, international financial organizations and other financial institutions. Historically, certain issuers of the government debt securities in which the Fund may invest have experienced substantial difficulties in meeting their external debt obligations, resulting in defaults on certain obligations and the restructuring of certain indebtedness. Such restructuring arrangements have included obtaining additional credit to finance outstanding obligations and the reduction and rescheduling of payments of interest and principal through the negotiation of new or amended credit agreements.

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.

Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security.

Foreign Investment Risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities. Foreign securities may have relatively low market liquidity, greater market volatility, decreased publicly available information, and less reliable financial information about issuers, and inconsistent and potentially less stringent accounting, auditing and financial reporting requirements and standards of practice comparable to those applicable to domestic issuers. Foreign securities also are subject to the risks of expropriation, nationalization, political instability or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in foreign securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions and higher transactional costs.

Global Bonds Risk. Global bonds are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities, including greater market volatility, the availability of less reliable financial information, higher transactional costs, taxation by foreign governments, decreased market liquidity and political instability.

Index Rebalance Risk. Pursuant to the methodology that the Index Provider uses to maintain the Underlying Index, securities may be frequently added or removed from the Underlying Index during regular Underlying Index rebalances. As a result, to the extent the Fund attempts to replicate the Underlying Index, the Fund may frequently buy or sell securities, increasing portfolio turnover. Higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. Additionally, Underlying Index rebalances may cause the Fund to purchase or 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 these factors, the variation between the Fund’s annual return and the return of the Underlying Index may increase significantly.

Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Industry Concentration Risk. The Underlying Index from time to time may be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries or sectors. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or sector may be out of favor and underperform other industries or the market as a whole.

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

Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price.

Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV.

Mortgage-Backed Securities Risk. Investments in mortgage-backed securities are subject to prepayment or call risk, which is the risk that payments from the borrower may be received earlier than expected due to changes in the rate at which the underlying loans are prepaid. Securities may be prepaid at a price less than the original purchase value.

Non-Correlation Risk. The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. Because the Fund issues and redeems Creation Units principally for cash, it will incur higher costs in buying and selling securities than if it issued and redeemed Creation Units in-kind. Additionally, the Fund’s use of a representative sampling approach may cause the Fund not to be as well-correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

Non-Diversified Fund Risk. Because the Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.

Non-Investment Grade Securities Risk. Non-investment grade securities are considered speculative and unrated securities of comparable credit quality are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of the non-investment grade securities markets generally, real or perceived adverse economic and competitive industry conditions and less secondary market liquidity. If the issuer of non-investment grade securities defaults, the Fund may incur additional expenses to seek recovery.

Privately Issued Securities Risk. The Fund may invest in privately issued securities, including those that may be resold only in accordance with Rule 144A or Regulation S under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded, and Regulation S securities are securities of U.S. and non-U.S. issuers initially offered and sold outside the United States without registration with the SEC. Accordingly, the liquidity of the market for specific Rule 144A or Regulation S securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund.

Sampling Risk. The Fund’s use of a representative sampling approach will result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development to an issuer of securities that the Fund holds could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater.

Sovereign Debt Risk. Investments in sovereign debt securities involve special risks. The governmental authority that controls the repayment of the debt may be unwilling or unable to repay the principal and/or interest when due in accordance with the terms of such securities due to the extent of its foreign reserves; the availability of sufficient foreign exchange on the date a payment is due; the relative size of the debt service burden to the economy as a whole; or the government debtor’s policy towards the International Monetary Fund and the political constraints to which a government debtor may be subject. If an issuer of sovereign debt defaults on payments of principal and/or interest, the Fund may have limited legal recourse against the issuer and/or guarantor. In certain cases, remedies must be pursued in the courts of the defaulting party itself, and the Fund’s ability to obtain recourse may be limited.

U.S. Government Obligation Risk. The Fund may invest in U.S. government obligations issued or guaranteed by the U.S. Government, its agencies and instrumentalities, including bills, notes and bonds issued by the U.S. Treasury. U.S. Government securities include securities that are issued or guaranteed by the United States Treasury, by various agencies of the U.S. Government, or by various instrumentalities which have been established or sponsored by the U.S. Government. U.S. Treasury securities are backed by the “full faith and credit” of the United States. Securities issued or guaranteed by federal agencies and U.S. Government-sponsored instrumentalities may or may not be backed by the full faith and credit of the United States. In the case of those U.S. Government securities not backed by the full faith and credit of the United States, the investor must look principally to the agency or instrumentality issuing or guaranteeing the security for ultimate repayment, and may not be able to assert a claim against the United States itself in the event that the agency or instrumentality does not meet its commitment. The U.S. Government, its agencies and instrumentalities do not guarantee the market value of their securities, and consequently, the value of such securities may fluctuate.

Valuation Risk. Financial information related to securities of non-U.S. issuers may be less reliable than information related to securities of U.S. issuers, which may make it difficult to obtain a current price for a non-U.S. security held by the Fund. In certain circumstances, market quotations may not be readily available for some Fund securities, and those securities may be fair valued. The value established for a security through fair valuation may be different from what would be produced if the security had been valued using market quotations. Fund securities that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. In addition, there is no assurance that the Fund could sell a portfolio security for the value established for it at any time, and it is possible that the Fund would incur a loss because a security is sold at a discount to its established value.

Valuation Time Risk. The Fund will invest in foreign bonds and, because foreign exchanges may be open on days when the Fund does not price its Shares, the value of the non-U.S. securities in the Fund’s portfolio may change on days when you will not be able to purchase or sell your Shares. As a result, trading spreads and the resulting premium or discount on the Shares may widen, and, therefore, increase the difference between the market price of the Shares and the Fund’s NAV of such Shares.

Strictly in accordance with its guidelines and mandated procedures, Invesco Indexing LLC (the “Index Provider”) compiles and maintains the Underlying Index, which is designed to provide multi-factor exposure to fixed income securities. The Index Provider is affiliated with Invesco Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”). The Underlying Index is an index of indexes, comprised of component securities of the following indexes (each, a “Sub-Index”), with corresponding fixed, target weightings in the Underlying Index: (i) Invesco High Yield Defensive Index (30% weight); (ii) Invesco Investment Grade Defensive Index (20% weight); (iii) Invesco U.S. Fixed Rate 30-Year MBS Index (20% weight); (iv) Invesco Investment Grade Value Index (10% weight); (v) Invesco U.S. Treasury 10-30 Years Index (10% weight); (vi) Invesco Emerging Markets Debt Defensive Index (5% weight); and (vii) Invesco Emerging Markets Debt Value Index (5% weight). The Underlying Index will typically include between 500-1,000 securities. The securities in the Underlying Index are weighted in accordance with the methodology of each Sub-Index. Additional information about each Sub-Index is set forth below. Invesco High Yield Defensive Index. The Invesco High Yield Defensive Index (the “HY Defensive Index”) is designed to provide exposure to U.S. high yield bonds (commonly known as “junk bonds”) having the highest “quality scores” (within the eligible universe of U.S. high yield bonds) as determined by the Index Provider using its methodology described below.. The HY Defensive Index is compiled and maintained by the Index Provider. In selecting components for inclusion in the HY Defensive Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by U.S. companies. To be eligible for inclusion in the HY Defensive Index, bonds must (i) be rated higher than B- and lower than BBB- (or equivalent) by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), Fitch Ratings Inc. (“Fitch”) or Moody’s Investors Service, Inc. (“Moody’s”) credit rating agencies; (ii) have at least $400 million outstanding, with only the largest bond from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Securities issued in accordance with Rule 144A (“Rule 144A securities”) under the Securities Act of 1933, as amended (the “Securities Act”) bonds registered with the Securities and Exchange Commission (“SEC”), publicly underwritten medium-term notes and Eurodollar bonds are all eligible for inclusion in the HY Defensive Index. The Index Provider assigns a quality score (“Quality Score”) to each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized across the universe of eligible bonds, and the Quality Score for each bond is computed as an equally-weighted combination of these two factors. All eligible securities are ranked by Quality Score. Initially, bonds with Quality Scores in the top 40% of eligible securities are selected for inclusion in the HY Defensive Index. At each monthly HY Defensive Index rebalance, any eligible security with a Quality Score in the top 30% of eligible securities is added to the HY Defensive Index, and current HY Defensive Index components with a Quality Score in the bottom 50% of eligible securities are removed. HY Defensive Index components are equally weighted. Invesco Investment Grade Defensive Index. The Invesco Investment Grade Defensive Index (the “IG Defensive Index”) is designed to provide exposure to U.S. investment grade bonds having the highest “quality scores” (within the eligible universe of U.S. investment grade bonds) as determined by the Index Provider using its methodology described below. The IG Defensive Index is compiled and maintained by the Index Provider. In selecting components for inclusion in the IG Defensive Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by U.S. companies. To be eligible for inclusion, bonds must (i) be rated higher than BBB- (or equivalent) by S&P, Fitch, or Moody’s credit rating agencies; (ii) have at least $600 million outstanding, with only the largest bond from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Rule 144A securities, bonds registered with the SEC, publicly underwritten medium-term notes and Eurodollar bonds are all eligible for inclusion in the IG Defensive Index. The Index Provider assigns a quality score (“Quality Score”) to each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized across the universe of eligible bonds, and the Quality Score for each bond is computed as an equally-weighted combination of these two factors. All eligible securities are ranked by Quality Score. Initially, bonds with Quality Scores in the top 40% of eligible securities are selected for inclusion in the IG Defensive Index. At each monthly IG Defensive Index rebalance, any eligible security with a Quality Score in the top 30% of eligible securities is added to the IG Defensive Index, and current components with a Quality Score in the bottom 50% of eligible securities are removed. IG Defensive Index components are equally weighted. Invesco U.S. Fixed Rate 30-Year MBS Index. The Invesco U.S. Fixed Rate 30-Year MBS Index (the “MBS Index”) is designed to provide exposure to mortgage-backed pass through securities of the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”). The MBS Index is compiled and maintained by the Index Provider. In selecting components for inclusion in the MBS Index, the Index Provider begins with an investment universe of generic aggregates (“MBS Generics”), which are groups of pools of mortgage-backed securities (“MBS”) based on shared issuing agent, coupon rate and production year (i.e., the year that the mortgages were originated). The MBS Generics include pools of 30-year mortgages issued by Fannie Mae and Freddie Mac. They are based on fixed rate mortgages with at least one year remaining to maturity. The total amount outstanding of all production years for a given issuer and coupon must be at least $5 billion, and the total amount outstanding for a given coupon must be at least $250 million. From the universe of MBS Generics, the MBS Index include all outstanding pools of 30-year mortgages issued by Fannie Mae and Freddie Mac that were produced in the past three years. The MBS Index rebalances monthly, at which time the MBS Generics selected for inclusion in the MBS Index are market-value weighted. Invesco Investment Grade Value Index. The Invesco Investment Grade Value Index (the “IG Value Index”) is designed to provide exposure to higher value, U.S. investment grade bonds. Higher value bonds are characterized as those with higher yields that may provide greater returns in certain markets. In addition, the IG Value seeks to incorporate securities with the highest “quality scores” (within the eligible universe of U.S. investment grade bonds) as determined by the Index Provider using its methodology described below. The IG Value Index is compiled and maintained by the Index Provider. In selecting components for inclusion in the IG Value Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by U.S. companies. To be eligible for inclusion, bonds must (i) be rated higher than BBB- (or equivalent) by S&P, Fitch, or Moody’s credit rating agencies; (ii) have at least $600 million outstanding, with only the largest bond from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Rule 144A securities, bonds registered with the SEC, publicly underwritten medium-term notes and Eurodollar bonds are all eligible for inclusion in the IG Value Index. The Index Provider assigns a QAV Score to each eligible bond, which is calculated based on a combination of value and quality factors or characteristics. With respect to value, a value score (“Value Score”) is assigned to each eligible bond based on the bond’s option adjusted spread (“OAS”). Specifically, the Value Score for each bond is calculated as its percentile ranked OAS within its sector and credit rating category. With respect to credit category, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The bond is then assigned to one of six credit rating categories, as established by the Index Provider. Bonds are also separately ranked by OAS solely within their credit rating category. If fewer than three bonds are available within a sector or credit rating, then the Value Score for all bonds in the grouping is replaced with the percentile rank based on credit rating only. If fewer than three bonds are available within a rating category, then the bonds in that rating category are removed from IG Value Index eligibility. The Value Scores are then standardized. The Index Provider also calculates a quality score (“Quality Score”) for each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized across the universe of eligible bonds, and the Quality Score for each bond is computed as an equally-weighted combination of these two factors. Once a Value Score and Quality Score are assigned to eligible bonds, the QAV Score is calculated as a weighted average combination of the two scores, with 90% and 10% weights applied to the Value Score and Quality Score, respectively. All eligible securities are ranked by the QAV Score. Initially, bonds with QAV Scores in the top 40% of eligible securities are selected for inclusion in the IG Value Index. At each monthly IG Value Index rebalance, any eligible security with a QAV Score in the top 30% of eligible securities is added to the IG Value Index, and current IG Value Index components with a QAV Score in the bottom 50% of eligible securities are removed. IG Value Index components are equally weighted. Invesco U.S. Treasury 10-30 Years Index. The Invesco U.S. Treasury 10-30 Years Index (the “Treasury 10-30 Years Index”) is compiled and maintained by the Index Provider and includes U.S dollar-denominated Treasury securities with a maturity from ten years up to thirty years, regardless of call features. To be eligible for inclusion, the securities must also have at least $1 billion par amount outstanding. The securities included in the Treasury 10-30 Years Index are market-value weighted. Invesco Emerging Markets Debt Defensive Index. The Invesco Emerging Markets Debt Defensive Index (the “EM Debt Defensive Index”) designed to provide exposure to emerging markets debt securities having the highest “quality scores” (within the eligible universe of emerging market debt securities) as determined by the Index Provider using its methodology described below. The EM Debt Defensive Index is compiled and maintained by the Index Provider. In selecting components for inclusion in the EM Debt Defensive Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by sovereign governments, and agencies thereof, of countries that that the Index Provider considers to be “emerging market countries” (as of June 15, 2018, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, Israel, Malaysia, Mexico, Morocco, Peru, the Philippines, Poland, Russia, South Africa, Taiwan, Thailand, Turkey, the United Arab Emirates and Vietnam). To be eligible for inclusion in the EM Debt Defensive Index, bonds must (i) be rated higher than B- (or equivalent) by S&P, Fitch or Moody’s credit rating agencies; (ii) have at least $500 million outstanding, with only the largest five bonds from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Rule 144A securities, securities issued in accordance with Regulation S under the Securities Act (“Regulation S securities”) and bonds registered with the SEC are all eligible for inclusion in the EM Debt Defensive Index. The Index Provider assigns a quality score (“Quality Score”) to each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to maturity, each bond is scored based on the number years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to credit factor score, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit factors for each bond are standardized by bond type (agency or sovereign), and the Quality Score for each bond is computed as a weighted-average combination of these two factors, with weights of 75% and 25% for maturity and credit rating, respectively. All eligible securities are ranked by Quality Score. Initially, bonds with quality scores in the top 40% of eligible securities are selected for inclusion in the EM Debt Defensive Index. At each monthly EM Debt Defensive Index rebalance, any eligible security with a Quality Score in the top 30% of eligible securities is added to the EM Debt Defensive Index, and current components with a Quality Score in the bottom 40% of eligible securities are removed. EM Debt Defensive Index components are modified market-value weighted. Invesco Emerging Markets Debt Value Index. The Invesco Emerging Markets Debt Value Index (the “EM Debt Value Index”) designed to provide exposure to higher value, emerging markets debt securities. Higher value bonds are characterized as those with higher yields that may provide greater returns in certain markets. In addition, the EM Debt Value Index seeks to incorporate securities with the highest “quality scores” (within the eligible universe of emerging market debt securities) as determined by the Index Provider using its methodology described below. The EM Debt Value Index is compiled and maintained by the Index Provider. In selecting components for inclusion in the EM Debt Value Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by sovereign governments, and agencies thereof, of countries that that the Index Provider considers to be “emerging market countries” (as of June 15, 2018, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, Israel, Malaysia, Mexico, Morocco, Peru, the Philippines, Poland, Russia, South Africa, Taiwan, Thailand, Turkey, the United Arab Emirates and Vietnam).

Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Rule 144A securities, Regulation S securities, and bonds registered with the SEC are all eligible for inclusion in the EM Debt Value Index. The Index Provider assigns a quality adjusted value score (“QAV Score”) to each eligible bond, which is calculated based on a combination of value and quality factors or characteristics. With respect to value, a value score (“Value Score”) is assigned to each eligible bond based on the bond’s option adjusted spread (“OAS”). Specifically, the Value Score for each bond is calculated as its percentile ranked OAS within its bond type (agency or sovereign), region and credit rating category. With respect to credit category, each rating agency’s rating is converted into a numerical value and a bond’s credit factor score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The bond is then assigned to one of six credit rating categories, as established by the Index Provider. Bonds are also separately ranked by OAS solely within their bond type category. If fewer than three bonds are available within a bond type, region or credit rating, then the Value Score for all bonds in the grouping is replaced with the percentile rank based on credit rating only.

EM Debt Value Index components are modified market-value weighted. The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund utilizes a “sampling” methodology to seek to achieve its investment objective. The Fund is “non-diversified” and therefore is not required to meet certain diversification requirements under the Investment Company Act of 1940, as amended (the “1940 Act”). Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries. As of the date of this prospectus, a significant portion of the Underlying Index is represented by the financial sector and, accordingly, the Adviser anticipates that the Fund may concentrate its investments in that sector. The Fund’s portfolio holdings, and the extent to which it concentrates in any industry or group of industries, are likely to change over time.

Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	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. Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs, and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that those APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities underlying the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with processing creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, which may be more likely to trade at a premium or discount to net asset value (“NAV”) and to face trading halts and/or delisting. This risk may be heightened for the Fund because it invests in non-U.S. securities, which may have lower trading volumes. Call Risk. If interest rates fall, it is possible that issuers of callable securities with high interest coupons will “call” (or prepay) their bonds before their maturity date. If an issuer exercised such a call during a period of declining interest rates, the Fund may have to replace such called security with a lower yielding security. If that were to happen, the Fund’s net investment income could fall. Cash Transaction Risk. Most ETFs generally make in-kind redemptions to avoid being taxed on gains on the distributed portfolio securities at the fund level. However, unlike most ETFs, the Fund currently intends to effect creations and redemptions principally for cash, rather than principally in-kind, due to the nature of the Fund’s investments. As such, the Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. Therefore, the Fund may recognize a capital gain on these sales that might not have been incurred if the Fund had made a redemption in-kind. This may decrease the tax efficiency of the Fund compared to ETFs that utilize an in-kind redemption process and there may be a substantial difference in the after-tax rate of return between the Fund and conventional ETFs. Changing Global Fixed-Income Market Conditions Risk. The current historically low interest rate environment was created in part by the Federal Reserve Board (“FRB”) and certain foreign central banks keeping the federal funds and equivalent foreign rates at, near or below zero. The “tapering” in 2015 of the FRB’s quantitative easing program, combined with the FRB’s recent raising of the target range for the Federal Funds Rate (and continued possible fluctuations in equivalent foreign rates) may expose fixed-income markets to heightened volatility and reduced liquidity for certain fixed-income investments, particularly those with longer maturities, although it is difficult to predict the impact of this rate increase and any future rate increases on various markets. In addition, decreases in fixed-income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed-income markets. As a result, the value of the Fund’s investments and share price may decline. Changes in central bank policies could also result in higher than normal shareholder redemptions, which could potentially increase portfolio turnover rate and the Fund’s transaction costs. Emerging Markets Sovereign Debt Risk. Government obligors in emerging market countries are among the world’s largest debtors to commercial banks, other governments, international financial organizations and other financial institutions. Historically, certain issuers of the government debt securities in which the Fund may invest have experienced substantial difficulties in meeting their external debt obligations, resulting in defaults on certain obligations and the restructuring of certain indebtedness. Such restructuring arrangements have included obtaining additional credit to finance outstanding obligations and the reduction and rescheduling of payments of interest and principal through the negotiation of new or amended credit agreements. 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. Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Foreign Investment Risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities. Foreign securities may have relatively low market liquidity, greater market volatility, decreased publicly available information, and less reliable financial information about issuers, and inconsistent and potentially less stringent accounting, auditing and financial reporting requirements and standards of practice comparable to those applicable to domestic issuers. Foreign securities also are subject to the risks of expropriation, nationalization, political instability or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in foreign securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions and higher transactional costs. Global Bonds Risk. Global bonds are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities, including greater market volatility, the availability of less reliable financial information, higher transactional costs, taxation by foreign governments, decreased market liquidity and political instability. Index Rebalance Risk. Pursuant to the methodology that the Index Provider uses to maintain the Underlying Index, securities may be frequently added or removed from the Underlying Index during regular Underlying Index rebalances. As a result, to the extent the Fund attempts to replicate the Underlying Index, the Fund may frequently buy or sell securities, increasing portfolio turnover. Higher portfolio turnover will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. Additionally, Underlying Index rebalances may cause the Fund to purchase or 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 these factors, the variation between the Fund’s annual return and the return of the Underlying Index may increase significantly. Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Industry Concentration Risk. The Underlying Index from time to time may be concentrated to a significant degree in securities of issuers located in a single industry or sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or sector, the Fund faces more risks than if it were diversified broadly over numerous industries or sectors. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or sector may be out of favor and underperform other industries or the market as a whole. Issuer-Specific Changes Risk. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price. Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to the Fund’s NAV. Mortgage-Backed Securities Risk. Investments in mortgage-backed securities are subject to prepayment or call risk, which is the risk that payments from the borrower may be received earlier than expected due to changes in the rate at which the underlying loans are prepaid. Securities may be prepaid at a price less than the original purchase value. Non-Correlation Risk. The Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Underlying Index. Because the Fund issues and redeems Creation Units principally for cash, it will incur higher costs in buying and selling securities than if it issued and redeemed Creation Units in-kind. Additionally, the Fund’s use of a representative sampling approach may cause the Fund not to be as well-correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints. Non-Diversified Fund Risk. Because the Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance. Non-Investment Grade Securities Risk. Non-investment grade securities are considered speculative and unrated securities of comparable credit quality are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of the non-investment grade securities markets generally, real or perceived adverse economic and competitive industry conditions and less secondary market liquidity. If the issuer of non-investment grade securities defaults, the Fund may incur additional expenses to seek recovery. Privately Issued Securities Risk. The Fund may invest in privately issued securities, including those that may be resold only in accordance with Rule 144A or Regulation S under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded, and Regulation S securities are securities of U.S. and non-U.S. issuers initially offered and sold outside the United States without registration with the SEC. Accordingly, the liquidity of the market for specific Rule 144A or Regulation S securities may vary. Delay or difficulty in selling such securities may result in a loss to the Fund. Sampling Risk. The Fund’s use of a representative sampling approach will result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development to an issuer of securities that the Fund holds could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater. Sovereign Debt Risk. Investments in sovereign debt securities involve special risks. The governmental authority that controls the repayment of the debt may be unwilling or unable to repay the principal and/or interest when due in accordance with the terms of such securities due to the extent of its foreign reserves; the availability of sufficient foreign exchange on the date a payment is due; the relative size of the debt service burden to the economy as a whole; or the government debtor’s policy towards the International Monetary Fund and the political constraints to which a government debtor may be subject. If an issuer of sovereign debt defaults on payments of principal and/or interest, the Fund may have limited legal recourse against the issuer and/or guarantor. In certain cases, remedies must be pursued in the courts of the defaulting party itself, and the Fund’s ability to obtain recourse may be limited. U.S. Government Obligation Risk. The Fund may invest in U.S. government obligations issued or guaranteed by the U.S. Government, its agencies and instrumentalities, including bills, notes and bonds issued by the U.S. Treasury. U.S. Government securities include securities that are issued or guaranteed by the United States Treasury, by various agencies of the U.S. Government, or by various instrumentalities which have been established or sponsored by the U.S. Government. U.S. Treasury securities are backed by the “full faith and credit” of the United States. Securities issued or guaranteed by federal agencies and U.S. Government-sponsored instrumentalities may or may not be backed by the full faith and credit of the United States. In the case of those U.S. Government securities not backed by the full faith and credit of the United States, the investor must look principally to the agency or instrumentality issuing or guaranteeing the security for ultimate repayment, and may not be able to assert a claim against the United States itself in the event that the agency or instrumentality does not meet its commitment. The U.S. Government, its agencies and instrumentalities do not guarantee the market value of their securities, and consequently, the value of such securities may fluctuate. Valuation Risk. Financial information related to securities of non-U.S. issuers may be less reliable than information related to securities of U.S. issuers, which may make it difficult to obtain a current price for a non-U.S. security held by the Fund. In certain circumstances, market quotations may not be readily available for some Fund securities, and those securities may be fair valued. The value established for a security through fair valuation may be different from what would be produced if the security had been valued using market quotations. Fund securities that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. In addition, there is no assurance that the Fund could sell a portfolio security for the value established for it at any time, and it is possible that the Fund would incur a loss because a security is sold at a discount to its established value. Valuation Time Risk. The Fund will invest in foreign bonds and, because foreign exchanges may be open on days when the Fund does not price its Shares, the value of the non-U.S. securities in the Fund’s portfolio may change on days when you will not be able to purchase or sell your Shares. As a result, trading spreads and the resulting premium or discount on the Shares may widen, and, therefore, increase the difference between the market price of the Shares and the Fund’s NAV of such Shares.
Risk Lose Money [Text]	rr_RiskLoseMoney	The Shares will change in value, and you could lose money by investing in the Fund.
Risk Nondiversified Status [Text]	rr_RiskNondiversifiedStatus	Non-Diversified Fund Risk. Because the Fund is non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund’s volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund’s performance.
