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

Annual Fund Operating Expenses	Invesco Investment Grade Value ETF Invesco Investment Grade Value ETF
Management Fees	0.13%
Other Expenses	none	[1]
Total Annual Fund Operating Expenses	0.13%

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	5 Years	10 Years
Invesco Investment Grade Value ETF | Invesco Investment Grade Value ETF | USD ($)	13	42	73	166

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. During the most recent fiscal year, the portfolio turnover rate of the Fund was 112% of the average value of its portfolio.

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) have an average credit rating that is 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 in face value 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 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 new eligible security with a QAV Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index constituents with a QAV Score in the top 50% of eligible securities remain in the Underlying Index provided that they satisfy all other eligibility criteria. Underlying Index constituents are equally weighted.  

As of August 31, 2019, the Underlying Index was comprised of 131 constituents.

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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates its investments, 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Portfolio Turnover Risk. The Fund may engage in frequent trading of its portfolio securities in connection with the rebalancing or adjustment of the Underlying Index. A portfolio turnover rate of 200%, for example, is equivalent to the Fund buying and selling all of its securities two times during the course of a year. A high portfolio turnover rate (such as 100% or more) could result in high brokerage costs for the Fund.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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.

Performance

The Fund commenced operations on July 23, 2018 and therefore does not yet have a full calendar year of performance history. Once the Fund has a full calendar year of performance information, the Fund will present total return information which is also accessible on the Fund’s website at www.invesco.com/ETFs and provides some indication of the risks of investing in the Fund.

[1] Other Expenses do not reflect any extraordinary expenses incurred during the most recent fiscal period, such as the costs associated with a proxy statement of the Fund. Had these expenses been included, Other Expenses would have been 0.03%.

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 62% of the average value of its portfolio.

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 such indexes (each, a “Sub-Index”). The Underlying Index weights the components of the following Sub-Indexes according to the following corresponding fixed, target weightings: (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).

As of August 31, 2019, the Underlying Index was comprised of 414 constituents.

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 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 includes 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.

Transactions in U.S. government agency mortgage-backed securities may occur through standardized agreements for forward or future delivery in which the actual mortgage pools to be delivered are not specified until shortly prior to settlement (to be announced (“TBA”) transactions). The Fund may engage in such TBA transactions.

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) have an average credit rating that is 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 in face value 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 new eligible security with a Quality Score in the top 30% of eligible securities is added to the IG Defensive Index, and current constituents with a Quality Score in the top 50% of eligible securities remain in the IG Defensive Index provided that they satisfy all other eligibility criteria. IG Defensive Index constituents 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 Treasury 1-3 Years Index constituents 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 Treasury 10-30 Years Index constituents 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 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 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) have an average credit rating that is higher than BBB- (or equivalent) by S&P, Fitch, or Moody’s credit rating agencies; (ii) have at least $600 million in face value 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 quality adjusted value (“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 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 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 new eligible security with a QAV Score in the top 30% of eligible securities is added to the IG Value Index, and current constituents with a QAV Score in the top 50% of eligible securities remain in the IG Value Index provided that they satisfy all other eligibility criteria. IG Value Index constituents 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns.

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. In addition, TBA transactions involve the risk that the securities received may be less favorable than what was anticipated by the Fund when entering into the TBA transaction and counterparty risk. Default or bankruptcy of a counterparty to a TBA transaction would expose the Fund to potential loss and could affect the Fund’s returns.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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.

Performance

The Fund commenced operations on July 23, 2018 and therefore does not yet have a full calendar year of performance history. Once the Fund has a full calendar year of performance information, the Fund will present total return information which is also accessible on the Fund’s website at www.invesco.com/ETFs and provides some indication of the risks of investing in the Fund.

Invesco BulletShares 2022 USD Emerging Markets Debt ETF

Invesco BulletShares 2022 USD Emerging Markets Debt ETF Summary Information

Investment Objective

The Invesco BulletShares 2022 USD Emerging Markets Debt ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Nasdaq BulletShares^® USD Emerging Markets Debt 2022 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 BulletShares 2022 USD Emerging Markets Debt ETF Invesco BulletShares 2022 USD Emerging Markets Debt 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	5 Years	10 Years
Invesco BulletShares 2022 USD Emerging Markets Debt ETF | Invesco BulletShares 2022 USD Emerging Markets Debt ETF | USD ($)	30	93	163	368

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the fiscal period October 2, 2018 (commencement of operations) through August 31, 2019, the portfolio turnover rate of the Fund was 15% of the average value of its portfolio.

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. 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 designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated emerging markets bonds with maturities or, in some cases, “effective maturities” in the year 2022 (collectively, “2022 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond, then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price, then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of investment grade and below investment grade U.S. dollar-denominated bonds issued by governments of countries that the Index Provider considers to be “emerging markets countries,” or by companies, sovereign entities or government-related agencies domiciled in such countries (as of August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, 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) have a credit rating of at least C by S&P Global Ratings, a division of S&P Global Inc. (“S&P”) or Fitch Ratings Inc. (“Fitch”), or at least a credit rating of Ca by Moody’s Investors Service, Inc. (“Moody’s”); and (ii) have an outstanding face value of at least $300 million for corporate bonds and $500 million for other bonds (existing bonds in the eligible universe require 80% of the initial minimum face value outstanding qualification, depending on type of bond, to remain eligible). Bonds rated below BBB- by S&P or Fitch, or below Baa3 by Moody’s are considered below investment grade (commonly known as “junk bonds”) and are considered speculative.

The eligible universe may include: fixed- and step up-coupon bonds; puttable and callable bonds; event-driven, rating-driven, and registration-driven bonds; amortizing bonds; sinking funds with fixed sinking schedules; and securities issued in accordance with Regulation S or Rule 144A under the Securities Act of 1933 (“Securities Act”) that are exempt from registration with the Securities and Exchange Commission (“SEC”). Additionally, bond types specifically excluded from the eligible universe include: private placements, except for Regulation S and Rule 144A bonds; pay-in-kind bonds; floating rate notes; zero coupon bonds, including zero coupon step-ups; convertible bonds; bonds cum or ex-warrant; bonds with one cash flow only; new bonds that have already been called; inflation or other index-linked bonds; bonds whose price, including interest that has accrued since the issue of the most recent coupon payment, is below $80; perpetual securities (including trust preferred); and preferred shares.

2022 Bonds (as established semi-annually, as further described below) in the eligible universe are selected for inclusion in the Underlying Index and market value weighted, with a 5% limit on individual issuers and a 10% limit on countries applied at each monthly rebalance. Prior to the final year of maturity (i.e., 2022), the Underlying Index is rebalanced monthly, at which time: (i) new bonds that meet the eligibility and maturity (or effective maturity) criteria above are added to the Underlying Index; (ii) existing 2022 Bonds that no longer meet the eligibility requirements are removed; and (iii) weights of Underlying Index components are reset to reflect current market value. The Index Provider only reevaluates the effective maturity date of bonds in the investment universe semi-annually, as part of the June and December rebalances, at which time in addition to bonds being added or removed from the Underlying Index pursuant to the eligibility screening described in the previous sentence, bonds also may be added or removed from the Underlying Index due to any changes in actual or effective maturity (i.e., they no longer meet the definition of 2022 Bond). If a bond is removed from the Underlying Index during any rebalance due to changes in face value or credit rating, such bond will be excluded for the next three monthly rebalances (including the current rebalance) regardless of any further changes in face value or credit rating. During the final year of maturity (i.e., 2022), the Underlying Index does not rebalance.

The Fund primarily invests in 2022 Bonds and the Fund will terminate on or about December 31, 2022. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. Bonds held by the Fund will be held until they mature, are called, or are removed from the Underlying Index due to no longer meeting the eligibility requirements. Ineligible bonds are not removed from an Underlying Index until its next rebalance. Therefore, to the extent a bond held by the Fund is no longer eligible for inclusion in an Underlying Index, the Fund will continue to hold such bond until it is removed from the respective Underlying Index at its next rebalance. In the last year of operation, when the 2022 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2022 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

As of August 31, 2019, the Underlying Index was comprised of 310 constituents.

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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates, 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

Emerging Markets Investment Risk. Investments in the securities of issuers in emerging market countries involve risks often not associated with investments in the securities of issuers in developed countries. Securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets. Fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in emerging market securities, and emerging market securities may have relatively low market liquidity, decreased publicly available 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. Emerging market securities also are subject to the risks of expropriation, nationalization or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in emerging market securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions. Emerging markets usually are subject to greater market volatility, lower trading volume, political and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Securities law in many emerging market countries is relatively new and unsettled. Therefore, laws regarding foreign investment in emerging market securities, securities regulation, title to securities, and shareholder rights may change quickly and unpredictably. In addition, the enforcement of systems of taxation at federal, regional and local levels in emerging market countries may be inconsistent and subject to sudden change.

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns.

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 and unrated securities of comparable credit quality are considered speculative and 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

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 may result in its holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development with respect to an issuer of securities held by the Fund 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

The Fund commenced operations on October 2, 2018 and therefore does not yet have a full calendar year of performance history. Once the Fund has a full calendar year of performance information, the Fund will present total return information, which is also accessible on the Fund’s website at www.invesco.com/ETFs and provides some indication of the risks of investing in the Fund.

[1] Other Expenses do not reflect any extraordinary expenses incurred during the most recent fiscal period, such as the costs associated with a proxy statement of the Fund. Had these expenses been included, Other Expenses would have been 0.03%.

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	5 Years	10 Years
Invesco Multi-Factor Core Plus Fixed Income ETF | Invesco Multi-Factor Core Plus Fixed Income ETF | USD ($)	16	52	90	205

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 69% of the average value of its portfolio.

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.

As of August 31, 2019, the Underlying Index was comprised of 716 constituents.

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. corporate bonds having the highest “quality scores” within an eligible universe of U.S. high yield bonds (commonly known as “junk bonds”) and bonds with the lowest credit rating considered investment grade, all 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) have an average credit rating that is higher than B- and lower than or equal to 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 in face value 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 new eligible security with a Quality Score in the top 30% of eligible securities is added to the HY Defensive Index, and current constituents with a Quality Score in the top 50% of eligible securities remain in the HY Defensive Index provided that they satisfy all other eligibility criteria. HY Defensive Index constituents 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) have an average credit rating that is higher than BBB- (or equivalent) by S&P, Fitch, or Moody’s credit rating agencies; (ii) have at least $600 million in face value 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 new eligible security with a Quality Score in the top 30% of eligible securities is added to the IG Defensive Index, and current constituents with a Quality Score in the top 50% of eligible securities remain in the IG Defensive Index provided that they satisfy all other eligibility criteria. IG Defensive Index constituents 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 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 includes 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.

Transactions in U.S. government agency mortgage-backed securities may occur through standardized agreements for forward or future delivery in which the actual mortgage pools to be delivered are not specified until shortly prior to settlement (to be announced (“TBA”) transactions). The Fund may engage in such TBA transactions.

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 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 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) have an average credit rating that is higher than BBB- (or equivalent) by S&P, Fitch, or Moody’s credit rating agencies; (ii) have at least $600 million in face value 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 quality adjusted value (“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 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 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 new eligible security with a QAV Score in the top 30% of eligible securities is added to the IG Value Index, and current constituents with a QAV Score in the top 50% of eligible securities remain in the IG Value Index provided that they satisfy all other eligibility criteria. IG Value Index constituents 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 the Index Provider considers to be “emerging market countries” (as of August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, 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) have an average credit rating that is higher than B- (or equivalent) by S&P, Fitch or Moody’s credit rating agencies; (ii) have at least $500 million in face value 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 new eligible security with a Quality Score in the top 30% of eligible securities is added to the EM Debt Defensive Index, and current constituents with a Quality Score in the top 60% of eligible securities remain in the EM Debt Defensive Index provided that they satisfy all other eligibility criteria. EM Debt Defensive Index constituents are modified market-value weighted.

Invesco Emerging Markets Debt Value Index. The Invesco Emerging Markets Debt Value Index (the “EM Debt Value Index”) 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 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 the Index Provider considers to be “emerging market countries” (as of August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, 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) have an average credit rating that is higher than B- (or equivalent) by S&P, Fitch or Moody’s credit rating agencies; (ii) have at least $500 million in face value 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 category, then the Value Score for all bonds in the grouping is replaced with the percentile rank based on bond type 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 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 new eligible security with a QAV Score in the top 30% of eligible securities is added to the EM Debt Value Index, and current constituents with a QAV Score in the top 60% of eligible securities remain in the EM Debt Value Index provided that they satisfy all other eligibility criteria. EM Debt Value Index constituents 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 changes to 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.

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 Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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. In addition, TBA transactions involve the risk that the securities received may be less favorable than what was anticipated by the Fund when entering into the TBA transaction and counterparty risk. Default or bankruptcy of a counterparty to a TBA transaction would expose the Fund to potential loss and could affect the Fund’s returns.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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.

Performance

The Fund commenced operations on July 23, 2018 and therefore does not yet have a full calendar year of performance history. Once the Fund has a full calendar year of performance information, the Fund will present total return information which is also accessible on the Fund’s website at www.invesco.com/ETFs and provides some indication of the risks of investing in the Fund.

Invesco BulletShares 2022 Corporate Bond ETF

Invesco BulletShares 2022 Corporate Bond ETF Summary Information

Investment Objective

The Invesco BulletShares 2022 Corporate Bond ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Nasdaq BulletShares^® USD Corporate Bond 2022 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 BulletShares 2022 Corporate Bond ETF Invesco BulletShares 2022 Corporate Bond ETF
Management Fees	0.10%
Other Expenses	none
Total Annual Fund Operating Expenses	0.10%

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	5 Years	10 Years
Invesco BulletShares 2022 Corporate Bond ETF | Invesco BulletShares 2022 Corporate Bond ETF | USD ($)	10	32	57	128

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 4% of the average value of its portfolio.

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.

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 seeks to measure the performance of a portfolio of U.S. dollar-denominated investment grade corporate bonds with maturities or, in some cases, “effective maturities” in the year 2022 (collectively, “2022 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) be rated at least BBB- by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or at least Baa3 by Moody’s Investors Service, Inc. (“Moody’s”); and (iii) have at least $500 million in face value outstanding (existing bonds in the eligible universe require $400 million in face value outstanding to remain eligible).

2022 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 375 constituents.

The Fund will terminate on or about December 15, 2022. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2022), no new constituents are added and the Underlying Index rebalances only through June. In the last six months of operation, when the 2022 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2022 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates, 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Sampling Risk. The Fund’s use of a representative sampling approach may 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.

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

The bar chart below shows how the Fund has performed. The table below the bar chart shows the Fund’s average annual total returns (before and after taxes). The bar chart and table provide an indication of the risks of investing in the Fund by showing how the Fund’s total returns have varied from year to year and by showing how the Fund’s average annual total returns compared with a broad measure of market performance and an additional index with characteristics relevant to the Fund. Although the information shown in the bar chart and the table gives you some idea of the risks involved in investing in the Fund, the Fund’s past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future.

The Fund is the successor to the investment performance of the Guggenheim BulletShares 2022 Corporate Bond ETF (the “Predecessor Fund”) as a result of the reorganization of the Predecessor Fund into the Fund, which was consummated after the close of business on April 6, 2018. Accordingly, the performance information shown below for periods ending on or prior to April 6, 2018 is that of the Predecessor Fund.

Invesco BulletShares 2021 USD Emerging Markets Debt ETF Summary Information

Investment Objective

The Invesco BulletShares 2021 USD Emerging Markets Debt ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Nasdaq BulletShares^® USD Emerging Markets Debt 2021 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)

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the fiscal period October 2, 2018 (commencement of operations) through August 31, 2019, the portfolio turnover rate of the Fund was 13% of the average value of its portfolio.

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. 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 designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated emerging markets bonds with maturities or, in some cases, “effective maturities” in the year 2021 (collectively, “2021 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond, then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price, then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of investment grade and below investment grade U.S. dollar-denominated bonds issued by governments of countries that the Index Provider considers to be “emerging markets countries,” or by companies, sovereign entities or government-related agencies domiciled in such countries (as of August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, 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) have a credit rating of at least C by S&P Global Ratings, a division of S&P Global Inc. (“S&P”) or Fitch Ratings Inc. (“Fitch”), or at least a credit rating of Ca by Moody’s Investors Service, Inc. (“Moody’s”); and (ii) have an outstanding face value of at least $300 million for corporate bonds and $500 million for other bonds (existing bonds in the eligible universe require 80% of the initial minimum face value outstanding qualification, depending on type of bond, to remain eligible). Bonds rated below BBB- by S&P or Fitch, or below Baa3 by Moody’s are considered below investment grade (commonly known as “junk bonds”) and are considered speculative.

The eligible universe may include: fixed- and step up-coupon bonds; puttable and callable bonds; event-driven, rating-driven, and registration-driven bonds; amortizing bonds; sinking funds with fixed sinking schedules; and securities issued in accordance with Regulation S or Rule 144A under the Securities Act of 1933 (“Securities Act”) that are exempt from registration with the Securities and Exchange Commission (“SEC”). Additionally, bond types specifically excluded from the eligible universe include: private placements, except for Regulation S and Rule 144A bonds; pay-in-kind bonds; floating rate notes; zero coupon bonds, including zero coupon step-ups; convertible bonds; bonds cum or ex-warrant; bonds with one cash flow only; new bonds that have already been called; inflation or other index-linked bonds; bonds whose price, including interest that has accrued since the issue of the most recent coupon payment, is below $80; perpetual securities (including trust preferred); and preferred shares.

2021 Bonds (as established semi-annually, as further described below) in the eligible universe are selected for inclusion in the Underlying Index and market value weighted, with a 5% limit on individual issuers and a 10% limit on countries applied at each monthly rebalance. Prior to the final year of maturity (i.e., 2021), the Underlying Index is rebalanced monthly, at which time: (i) new bonds that meet the eligibility and maturity (or effective maturity) criteria above are added to the Underlying Index; (ii) existing 2021 Bonds that no longer meet the eligibility requirements are removed; and (iii) weights of Underlying Index components are reset to reflect current market value. The Index Provider only reevaluates the effective maturity date of bonds in the investment universe semi-annually, as part of the June and December rebalances, at which time in addition to bonds being added or removed from the Underlying Index pursuant to the eligibility screening described in the previous sentence, bonds also may be added or removed from the Underlying Index due to any changes in actual or effective maturity (i.e., they no longer meet the definition of 2021 Bond). If a bond is removed from the Underlying Index during any rebalance due to changes in face value or credit rating, such bond will be excluded for the next three monthly rebalances (including the current rebalance) regardless of any further changes in face value or credit rating. During the final year of maturity (i.e., 2021), the Underlying Index does not rebalance.

The Fund primarily invests in 2021 Bonds and the Fund will terminate on or about December 31, 2021. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. Bonds held by the Fund will be held until they mature, are called, or are removed from the Underlying Index due to no longer meeting the eligibility requirements. Ineligible bonds are not removed from an Underlying Index until its next rebalance. Therefore, to the extent a bond held by the Fund is no longer eligible for inclusion in an Underlying Index, the Fund will continue to hold such bond until it is removed from the respective Underlying Index at its next rebalance. In the last year of operation, when the 2021 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2021 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

As of August 31, 2019, the Underlying Index was comprised of 261 constituents.

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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates, 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

Emerging Markets Investment Risk. Investments in the securities of issuers in emerging market countries involve risks often not associated with investments in the securities of issuers in developed countries. Securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets. Fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in emerging market securities, and emerging market securities may have relatively low market liquidity, decreased publicly available 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. Emerging market securities also are subject to the risks of expropriation, nationalization or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in emerging market securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions. Emerging markets usually are subject to greater market volatility, lower trading volume, political and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Securities law in many emerging market countries is relatively new and unsettled. Therefore, laws regarding foreign investment in emerging market securities, securities regulation, title to securities, and shareholder rights may change quickly and unpredictably. In addition, the enforcement of systems of taxation at federal, regional and local levels in emerging market countries may be inconsistent and subject to sudden change.

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns.

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 and unrated securities of comparable credit quality are considered speculative and 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

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 may result in its holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development with respect to an issuer of securities held by the Fund 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

The Fund commenced operations on October 2, 2018 and therefore does not yet have a full calendar year of performance history. Once the Fund has a full calendar year of performance information, the Fund will present total return information, which is also accessible on the Fund’s website at www.invesco.com/ETFs and provides some indication of the risks of investing in the Fund.

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”) and bonds with the lowest credit rating considered investment grade. 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. 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) have an average credit rating that is higher than B- and lower than or equal to 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 in face value 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 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 new eligible security with a QAV Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index constituents with a QAV Score in the top 50% of eligible securities remain in the Underlying Index provided that they satisfy all other eligibility criteria. Underlying Index constituents are equally weighted.   As of August 31, 2019, the Underlying Index was comprised of 197 constituents. 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. 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 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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. Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. Portfolio Turnover Risk. The Fund may engage in frequent trading of its portfolio securities in connection with the rebalancing or adjustment of the Underlying Index. A portfolio turnover rate of 200%, for example, is equivalent to the Fund buying and selling all of its securities two times during the course of a year. A high portfolio turnover rate (such as 100% or more) could result in high brokerage costs for the Fund. Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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.
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.

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. corporate bonds having the highest “quality scores” within an eligible universe of U.S. high yield bonds (commonly known as “junk bonds”) and bonds with the lowest credit rating considered investment grade, all 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) have an average credit rating that is higher than B- and lower than or equal to 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 in face value 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 new eligible security with a Quality Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index constituents with a Quality Score in the top 50% of eligible securities remain in the Underlying Index provided that they satisfy all other eligibility criteria. Underlying Index constituents are equally weighted.   As of August 31, 2019, the Underlying Index was comprised of 159 constituents. 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. 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 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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. Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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. 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 designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated emerging markets bonds with maturities or, in some cases, “effective maturities” in the year 2023 (collectively, “2023 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond, then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price, then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date. In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of investment grade and below investment grade U.S. dollar-denominated bonds issued by governments of countries that the Index Provider considers to be “emerging markets countries,” or by companies, sovereign entities or government-related agencies domiciled in such countries (as of August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, 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) have a credit rating of at least C by S&P Global Ratings, a division of S&P Global Inc. (“S&P”) or Fitch Ratings Inc. (“Fitch”), or at least a credit rating of Ca by Moody’s Investors Service, Inc. (“Moody’s”); and (ii) have an outstanding face value of at least $300 million for corporate bonds and $500 million for other bonds (existing bonds in the eligible universe require 80% of the initial minimum face value outstanding qualification, depending on type of bond, to remain eligible). Bonds rated below BBB- by S&P or Fitch, or below Baa3 by Moody’s are considered below investment grade (commonly known as “junk bonds”) and are considered speculative. The eligible universe may include: fixed- and step up-coupon bonds; puttable and callable bonds; event-driven, rating-driven, and registration-driven bonds; amortizing bonds; sinking funds with fixed sinking schedules; and securities issued in accordance with Regulation S or Rule 144A under the Securities Act of 1933 (“Securities Act”) that are exempt from registration with the Securities and Exchange Commission (“SEC”). Additionally, bond types specifically excluded from the eligible universe include: private placements, except for Regulation S and Rule 144A bonds; pay-in-kind bonds; floating rate notes; zero coupon bonds, including zero coupon step-ups; convertible bonds; bonds cum or ex-warrant; bonds with one cash flow only; new bonds that have already been called; inflation or other index-linked bonds; bonds whose price, including interest that has accrued since the issue of the most recent coupon payment, is below $80; perpetual securities (including trust preferred); and preferred shares. 2023 Bonds (as established semi-annually, as further described below) in the eligible universe are selected for inclusion in the Underlying Index and market value weighted, with a 5% limit on individual issuers and a 10% limit on countries applied at each monthly rebalance. Prior to the final year of maturity (i.e., 2023), the Underlying Index is rebalanced monthly, at which time: (i) new bonds that meet the eligibility and maturity (or effective maturity) criteria above are added to the Underlying Index; (ii) existing 2023 Bonds that no longer meet the eligibility requirements are removed; and (iii) weights of Underlying Index components are reset to reflect current market value. The Index Provider only reevaluates the effective maturity date of bonds in the investment universe semi-annually, as part of the June and December rebalances, at which time in addition to bonds being added or removed from the Underlying Index pursuant to the eligibility screening described in the previous sentence, bonds also may be added or removed from the Underlying Index due to any changes in actual or effective maturity (i.e., they no longer meet the definition of 2023 Bond). If a bond is removed from the Underlying Index during any rebalance due to changes in face value or credit rating, such bond will be excluded for the next three monthly rebalances (including the current rebalance) regardless of any further changes in face value or credit rating. During the final year of maturity (i.e., 2023), the Underlying Index does not rebalance. The Fund primarily invests in 2023 Bonds and the Fund will terminate on or about December 31, 2023. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. Bonds held by the Fund will be held until they mature, are called, or are removed from the Underlying Index due to no longer meeting the eligibility requirements. Ineligible bonds are not removed from an Underlying Index until its next rebalance. Therefore, to the extent a bond held by the Fund is no longer eligible for inclusion in an Underlying Index, the Fund will continue to hold such bond until it is removed from the respective Underlying Index at its next rebalance. In the last year of operation, when the 2023 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2023 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time. As of August 31, 2019, the Underlying Index was comprised of 249 constituents. 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. 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 exercises 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 changes to 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. Declining Yield Risk. During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market. Emerging Markets Investment Risk. Investments in the securities of issuers in emerging market countries involve risks often not associated with investments in the securities of issuers in developed countries. Securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets. Fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in emerging market securities, and emerging market securities may have relatively low market liquidity, decreased publicly available 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. Emerging market securities also are subject to the risks of expropriation, nationalization or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in emerging market securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions. Emerging markets usually are subject to greater market volatility, lower trading volume, political and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Securities law in many emerging market countries is relatively new and unsettled. Therefore, laws regarding foreign investment in emerging market securities, securities regulation, title to securities, and shareholder rights may change quickly and unpredictably. In addition, the enforcement of systems of taxation at federal, regional and local levels in emerging market countries may be inconsistent and subject to sudden change. 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. Fluctuation of Yield and Liquidation Amount Risk. The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes. Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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. 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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. Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. 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 and unrated securities of comparable credit quality are considered speculative and 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. 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 may result in its holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development with respect to an issuer of securities held by the Fund 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. 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.

Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the fiscal period October 2, 2018 (commencement of operations) through August 31, 2019, the portfolio turnover rate of the Fund was 10% of the average value of its portfolio.

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. 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 designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated emerging markets bonds with maturities or, in some cases, “effective maturities” in the year 2024 (collectively, “2024 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond, then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price, then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date. In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of investment grade and below investment grade U.S. dollar-denominated bonds issued by governments of countries that the Index Provider considers to be “emerging markets countries,” or by companies, sovereign entities or government-related agencies domiciled in such countries (as of August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, 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) have a credit rating of at least C by S&P Global Ratings, a division of S&P Global Inc. (“S&P”) or Fitch Ratings Inc. (“Fitch”), or at least a credit rating of Ca by Moody’s Investors Service, Inc. (“Moody’s”); and (ii) have an outstanding face value of at least $300 million for corporate bonds and $500 million for other bonds (existing bonds in the eligible universe require 80% of the initial minimum face value outstanding qualification, depending on type of bond, to remain eligible). Bonds rated below BBB- by S&P or Fitch, or below Baa3 by Moody’s are considered below investment grade (commonly known as “junk bonds”) and are considered speculative. The eligible universe may include: fixed- and step up-coupon bonds; puttable and callable bonds; event-driven, rating-driven, and registration-driven bonds; amortizing bonds; sinking funds with fixed sinking schedules; and securities issued in accordance with Regulation S or Rule 144A under the Securities Act of 1933 (“Securities Act”) that are exempt from registration with the Securities and Exchange Commission (“SEC”). Additionally, bond types specifically excluded from the eligible universe include: private placements, except for Regulation S and Rule 144A bonds; pay-in-kind bonds; floating rate notes; zero coupon bonds, including zero coupon step-ups; convertible bonds; bonds cum or ex-warrant; bonds with one cash flow only; new bonds that have already been called; inflation or other index-linked bonds; bonds whose price, including interest that has accrued since the issue of the most recent coupon payment, is below $80; perpetual securities (including trust preferred); and preferred shares. 2024 Bonds (as established semi-annually, as further described below) in the eligible universe are selected for inclusion in the Underlying Index and market value weighted, with a 5% limit on individual issuers and a 10% limit on countries applied at each monthly rebalance. Prior to the final year of maturity (i.e., 2024), the Underlying Index is rebalanced monthly, at which time: (i) new bonds that meet the eligibility and maturity (or effective maturity) criteria above are added to the Underlying Index; (ii) existing 2024 Bonds that no longer meet the eligibility requirements are removed; and (iii) weights of Underlying Index components are reset to reflect current market value. The Index Provider only reevaluates the effective maturity date of bonds in the investment universe semi-annually, as part of the June and December rebalances, at which time in addition to bonds being added or removed from the Underlying Index pursuant to the eligibility screening described in the previous sentence, bonds also may be added or removed from the Underlying Index due to any changes in actual or effective maturity (i.e., they no longer meet the definition of 2024 Bond). If a bond is removed from the Underlying Index during any rebalance due to changes in face value or credit rating, such bond will be excluded for the next three monthly rebalances (including the current rebalance) regardless of any further changes in face value or credit rating. During the final year of maturity (i.e., 2024), the Underlying Index does not rebalance. The Fund primarily invests in 2024 Bonds and the Fund will terminate on or about December 31, 2024. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. Bonds held by the Fund will be held until they mature, are called, or are removed from the Underlying Index due to no longer meeting the eligibility requirements. Ineligible bonds are not removed from an Underlying Index until its next rebalance. Therefore, to the extent a bond held by the Fund is no longer eligible for inclusion in an Underlying Index, the Fund will continue to hold such bond until it is removed from the respective Underlying Index at its next rebalance. In the last year of operation, when the 2024 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2024 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time. As of August 31, 2019, the Underlying Index was comprised of 216 constituents. 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.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. 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 exercises 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 changes to 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. Declining Yield Risk. During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market. Emerging Markets Investment Risk. Investments in the securities of issuers in emerging market countries involve risks often not associated with investments in the securities of issuers in developed countries. Securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets. Fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in emerging market securities, and emerging market securities may have relatively low market liquidity, decreased publicly available 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. Emerging market securities also are subject to the risks of expropriation, nationalization or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in emerging market securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions. Emerging markets usually are subject to greater market volatility, lower trading volume, political and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Securities law in many emerging market countries is relatively new and unsettled. Therefore, laws regarding foreign investment in emerging market securities, securities regulation, title to securities, and shareholder rights may change quickly and unpredictably. In addition, the enforcement of systems of taxation at federal, regional and local levels in emerging market countries may be inconsistent and subject to sudden change. 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. Fluctuation of Yield and Liquidation Amount Risk. The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes. Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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. 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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. Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. 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 and unrated securities of comparable credit quality are considered speculative and 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. 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 may result in its holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development with respect to an issuer of securities held by the Fund 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. 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 BulletShares 2021 High Yield Corporate Bond ETF

Invesco BulletShares 2021 High Yield Corporate Bond ETF Summary Information

Investment Objective

The Invesco BulletShares 2021 High Yield Corporate Bond ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Nasdaq BulletShares^® USD High Yield Corporate Bond 2021 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)

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 52% of the average value of its portfolio.

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated high yield corporate bonds (commonly known as “junk bonds”) with maturities or, in some cases, “effective maturities” in the year 2021 (collectively, “2021 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) have a maximum rating of BB+ from S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or a maximum rating of Ba1 from Moody’s Investors Service, Inc. (“Moody’s”); (iii) have a minimum average credit rating (computed by calculating the simple average of a bond’s rating published by S&P, Fitch and Moody’s and then rounding down to the nearest rating step) of CCC- from S&P, Fitch and Moody’s; and (iv) have at least $200 million in face value outstanding (existing bonds in the eligible universe require $150 million in face value outstanding to remain eligible).

The eligible universe may include securities issued in accordance with Rule 144A under the Securities Act of 1933, as amended (“Securities Act”).

2021 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 122 constituents.

The Fund will terminate on or about December 15, 2021. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2021), no new constituents are added and the Underlying Index does not rebalance. In the last twelve months of operation, when the 2021 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2021 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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 may 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.

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

The bar chart below shows how the Fund has performed. The table below the bar chart shows the Fund’s average annual total returns (before and after taxes). The bar chart and table provide an indication of the risks of investing in the Fund by showing how the Fund’s total returns have varied from year to year and by showing how the Fund’s average annual total returns compared with a broad measure of market performance and an additional index with characteristics relevant to the Fund. Although the information shown in the bar chart and the table gives you some idea of the risks involved in investing in the Fund, the Fund’s past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future.

The Fund is the successor to the investment performance of the Guggenheim BulletShares 2021 High Yield Corporate Bond ETF (the “Predecessor Fund”) as a result of the reorganization of the Predecessor Fund into the Fund, which was consummated after the close of business on April 6, 2018. Accordingly, the performance information shown below for periods ending on or prior to April 6, 2018 is that of the Predecessor Fund.

Invesco BulletShares 2022 High Yield Corporate Bond ETF

Invesco BulletShares 2022 High Yield Corporate Bond ETF Summary Information

Investment Objective

The Invesco BulletShares 2022 High Yield Corporate Bond ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Nasdaq BulletShares^® USD High Yield Corporate Bond 2022 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 BulletShares 2022 High Yield Corporate Bond ETF Invesco BulletShares 2022 High Yield Corporate Bond ETF
Management Fees	0.42%
Other Expenses	none
Total Annual Fund Operating Expenses	0.42%

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	5 Years	10 Years
Invesco BulletShares 2022 High Yield Corporate Bond ETF | Invesco BulletShares 2022 High Yield Corporate Bond ETF | USD ($)	43	135	235	530

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 27% of the average value of its portfolio.

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated high yield corporate bonds (commonly known as “junk bonds”) with maturities or, in some cases, “effective maturities” in the year 2022 (collectively, “2022 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) have a maximum rating of BB+ from S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or a maximum rating of Ba1 from Moody’s Investors Service, Inc. (“Moody’s”); (iii) have a minimum average credit rating (computed by calculating the simple average of a bond’s rating published by S&P, Fitch and Moody’s and then rounding down to the nearest rating step) of CCC- from S&P, Fitch and Moody’s; and (iv) have at least $200 million in face value outstanding (existing bonds in the eligible universe require $150 million in face value outstanding to remain eligible).

The eligible universe may include securities issued in accordance with Rule 144A under the Securities Act of 1933, as amended (“Securities Act”).

2022 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 177 constituents.

The Fund will terminate on or about December 15, 2022. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2022), no new constituents are added and the Underlying Index does not rebalance. In the last twelve months of operation, when the 2022 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2022 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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 may 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.

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

The bar chart below shows how the Fund has performed. The table below the bar chart shows the Fund’s average annual total returns (before and after taxes). The bar chart and table provide an indication of the risks of investing in the Fund by showing how the Fund’s total returns have varied from year to year and by showing how the Fund’s average annual total returns compared with a broad measure of market performance and an additional index with characteristics relevant to the Fund. Although the information shown in the bar chart and the table gives you some idea of the risks involved in investing in the Fund, the Fund’s past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future.

The Fund is the successor to the investment performance of the Guggenheim BulletShares 2022 High Yield Corporate Bond ETF (the “Predecessor Fund”) as a result of the reorganization of the Predecessor Fund into the Fund, which was consummated after the close of business on April 6, 2018. Accordingly, the performance information shown below for periods ending on or prior to April 6, 2018 is that of the Predecessor Fund. Updated performance information is available online at www.invesco.com/ETFs.

Invesco RAFI(TM) Strategic Emerging Markets ETF

Invesco RAFI™ Strategic Emerging Markets ETF Summary Information

Investment Objective

The Invesco RAFI^TM Strategic Emerging Markets ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Invesco Strategic Emerging Markets 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 RAFI(TM) Strategic Emerging Markets ETF Invesco RAFI(TM) Strategic Emerging Markets ETF
Management Fees	0.35%
Other Expenses	none	[1]
Total Annual Fund Operating Expenses	0.35%

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	5 Years	10 Years
Invesco RAFI(TM) Strategic Emerging Markets ETF | Invesco RAFI(TM) Strategic Emerging Markets ETF | USD ($)	36	113	197	443

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the fiscal period September 10, 2018 (commencement of operations) through August 31, 2019, the Fund’s portfolio turnover rate was 22% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in securities that comprise the Underlying Index and American depositary receipts (“ADRs”) and global depositary receipts (“GDRs”) that are based on securities in 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 measure the performance of equity securities issued by higher quality, large-business-sized companies located in countries designated as emerging market countries. 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 Index Provider selects components for inclusion in the Underlying Index from an investment universe of foreign equity securities with at least one year of trading history, issued by companies located in countries designated as emerging market countries. Each eligible equity security is assigned a business-size score (“Business-Size Score”) based on the equally-weighted average of the following four factors of company size over the prior five years (or, if shorter, the life of the security): sales, operating cash flow, total return of capital (dividends and share repurchases) and book value. For real estate securities (real estate investment trusts (“REITs”) and common stocks of companies in the real estate sector), operating cash flow is replaced by funds from operations and book value is replaced by total assets.

Each eligible security is then assigned a quality score (“Quality Score”) based on the equally-weighted average of the following two quality factors of its company’s business: efficiency (calculated as the ratio of sales-to-assets in the prior year) and growth (calculated as the percentage change in the ratio of sales-to-assets over the prior five years (or, if shorter, the life of the security)).

Each eligible security is ranked in descending order by its Business-Size Score. Those securities in the top 90% by Business-Size Score are eligible for inclusion in the Underlying Index and, of those, the 80% with the highest Quality Scores are included in the Underlying Index. Securities in the Underlying Index are weighted based on their float-adjusted Business-Size Scores.

As of August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, Malaysia, Mexico, Morocco, Peru, the Philippines, Poland, Russia, South Africa, Taiwan, Thailand, Turkey, the United Arab Emirates and Vietnam.

As of August 31, 2019, the Underlying Index was comprised of 376 constituents.

The Fund employs a “full replication” methodology in seeking to track the Underlying Index, meaning that the Fund generally invests in all of the securities comprising the Underlying Index in proportion to their weightings in the Underlying Index.

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.

ADR and GDR Risk. ADRs are certificates that evidence ownership of shares of a foreign issuer and are alternatives to purchasing the underlying foreign securities directly in their national markets and currencies. GDRs are certificates issued by an international bank that generally are traded and denominated in the currencies of countries other than the home country of the issuer of the underlying shares. ADRs and GDRs may be subject to certain of the risks associated with direct investments in the securities of foreign companies, such as currency, political, economic and market risks, because their values depend on the performance of the non-dollar denominated underlying foreign securities. Moreover, ADRs and GDRs may not track the price of the underlying foreign securities on which they are based, and their value may change materially at times when U.S. markets are not open for trading.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

China Exposure Risk. The value of securities of companies that derive the majority of their revenues from China is likely to be more volatile than that of other issuers. The economy of China differs, often unfavorably, from the U.S. economy in such respects as structure, general development, government involvement, wealth distribution, rate of inflation, growth rate, allocation of resources and capital reinvestment. The Chinese central government historically has exercised substantial control over virtually every sector of the Chinese economy through administrative regulation and/or state ownership. Actions of the Chinese government authorities continue to have a substantial effect on economic conditions in China. It is difficult for non-Chinese investors to directly access securities in China because of investment and trading restrictions. These limitations and restrictions may impact the availability, liquidity, and pricing of certain securities.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar. Generally, an increase in the value of the U.S. dollar against a foreign currency will reduce the value of a security denominated in that foreign currency, thereby decreasing the Fund’s overall NAV. Exchange rates may be volatile and may change quickly and unpredictably in response to both global economic developments and economic conditions, causing an adverse impact on the Fund. As a result, investors have the potential for losses regardless of the length of time they intend to hold Shares.

Emerging Markets Investment Risk. Investments in the securities of issuers in emerging market countries involve risks often not associated with investments in the securities of issuers in developed countries. Securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets. Fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in emerging market securities, and emerging market securities may have relatively low market liquidity, decreased publicly available 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. Emerging market securities also are subject to the risks of expropriation, nationalization or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in emerging market securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions. Emerging markets are subject to greater market volatility, lower trading volume, political and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Securities law in many emerging market countries is relatively new and unsettled. Therefore, laws regarding foreign investment in emerging market securities, securities regulation, title to securities, and shareholder rights may change quickly and unpredictably. In addition, the enforcement of systems of taxation at federal, regional and local levels in emerging market countries may be inconsistent and subject to sudden change.

Equity Risk. Equity risk is the risk that the value of equity securities, including common stocks, may fall due to both changes in general economic conditions that impact the market as a whole, as well as factors that directly relate to a specific company or its industry. Such general economic conditions include changes in interest rates, periods of market turbulence or instability, or general and prolonged periods of economic decline and cyclical change. It is possible that a drop in the stock market may depress the price of most or all of the common stocks that the Fund holds.

In addition, equity risk includes the risk that investor sentiment toward one or more industries will become negative, resulting in those investors exiting their investments in those industries, which could cause a reduction in the value of companies in those industries more broadly. The value of a company’s common stock may fall solely because of factors, such as an increase in production costs, that negatively impact other companies in the same region, industry or sector of the market. A company’s common stock also may decline significantly in price over a short period of time due to factors specific to that company, including decisions made by its management or lower demand for the company’s products or services. For example, an adverse event, such as an unfavorable earnings report or the failure to make anticipated dividend payments, may depress the value of common stock.

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. As the Fund will invest in securities denominated in foreign currencies, fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in foreign securities and may negatively impact the Fund’s returns.

Geographic Concentration Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in that specific geographic region and adversely impact the Fund’s investments in the affected region.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares, or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns.

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.

Mid-Capitalization Company Risk. Investing in securities of mid-capitalization companies involves greater risk than is customarily associated with investing in larger, more established companies. These companies’ securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often mid-capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions.

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. 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

REIT Risk. REITs are subject to risks inherent in the direct ownership of real estate. These risks include, but are not limited to, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. REITs may be affected by changes in the values of the underlying properties that they own or operate and could fail to qualify for favorable tax or regulatory treatment. REITs also are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs rely heavily on cash flows and a variety of economic and other factors may adversely affect a lessee’s ability to meet its obligations to a REIT. Should a lessee default on their loan, the REIT may experience delays in enforcing its rights as a lessor and may incur substantial costs associated in protecting its investments.

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 securities and, because foreign exchanges may be open on days when the Fund does not price its Shares, the value of those 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 NAV of such Shares.

Performance

The Fund commenced operations on September 10, 2018 and therefore does not have a full calendar year of performance history. Once the Fund has a full calendar year of performance information, the Fund will present total return information, which is also accessible on the Fund’s website at www.invesco.com/ETFs and provides some indication of the risks of investing in the Fund.

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 measure the performance of equity securities issued by higher quality, large-business-sized companies designated as U.S. companies. 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 Index Provider selects components for inclusion in the Underlying Index from an investment universe of domestic equity securities with at least one year of trading history. Each eligible equity security is assigned a business-size score (“Business-Size Score”) based on the equally-weighted average of the following four factors of company size over the prior five years (or, if shorter, the life of the security): sales, operating cash flow, total return of capital (dividends and share repurchases) and book value. For real estate securities (real estate investment trusts (“REITs”) and common stocks of companies in the real estate sector), operating cash flow is replaced by funds from operations and book value is replaced by total assets. Each eligible security is then assigned a quality score (“Quality Score”) based on the equally-weighted average of the following two quality factors of its company’s business: efficiency (calculated as the ratio of sales-to-assets in the prior year) and growth (calculated as the percentage change in the ratio of sales-to-assets over the prior five years (or, if shorter, the life of the security)). Each eligible security is ranked in descending order by its Business-Size Score. Those securities in the top 90% by Business-Size Score are eligible for inclusion in the Underlying Index and, of those, the 80% with the highest Quality Scores are included in the Underlying Index. Securities in the Underlying Index are weighted based on their float-adjusted Business-Size Scores. As of August 31, 2019, the Underlying Index was comprised of 545 constituents. The Fund employs a “full replication” methodology in seeking to track the Underlying Index, meaning that the Fund generally invests in all of the securities comprising the Underlying Index in proportion to their weightings in the Underlying Index. 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. Equity Risk. Equity risk is the risk that the value of equity securities, including common stocks, may fall due to both changes in general economic conditions that impact the market as a whole, as well as factors that directly relate to a specific company or its industry. Such general economic conditions include changes in interest rates, periods of market turbulence or instability, or general and prolonged periods of economic decline and cyclical change. It is possible that a drop in the stock market may depress the price of most or all of the common stocks that the Fund holds. In addition, equity risk includes the risk that investor sentiment toward one or more industries will become negative, resulting in those investors exiting their investments in those industries, which could cause a reduction in the value of companies in those industries more broadly. The value of a company’s common stock may fall solely because of factors, such as an increase in production costs, that negatively impact other companies in the same region, industry or sector of the market. A company’s common stock also may decline significantly in price over a short period of time due to factors specific to that company, including decisions made by its management or lower demand for the company’s products or services. For example, an adverse event, such as an unfavorable earnings report or the failure to make anticipated dividend payments, may depress the value of common stock. 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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. 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. 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. REIT Risk. REITs are subject to risks inherent in the direct ownership of real estate. These risks include, but are not limited to, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. REITs may be affected by changes in the values of the underlying properties that they own or operate and could fail to qualify for favorable tax or regulatory treatment. REITs also are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs rely heavily on cash flows and a variety of economic and other factors may adversely affect a lessee’s ability to meet its obligations to a REIT. Should a lessee default on their loan, the REIT may experience delays in enforcing its rights as a lessor and may incur substantial costs associated in protecting its investments.

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 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 other indexes and is comprised of component securities of such indexes (each, a “Sub-Index”). The Underlying Index weights the components of the following Sub-Indexes according to the following corresponding fixed, target weightings: (i) Invesco U.S. Fixed Rate 30-Year MBS Index (25% weight); (ii) Invesco Emerging Markets Debt Value Index (15% weight); (iii) Invesco High Yield Defensive Index (15% weight); (iv) Invesco Investment Grade Value Index (15% weight); (v) Invesco Emerging Markets Debt Defensive Index (10% weight); (vi) Invesco High Yield Value Index (10% weight); and (vii) Invesco Investment Grade Defensive Index (10% weight). The Underlying Index will typically include between 500-1,000 securities. The securities in the Underlying Index are weighted pursuant to the Sub-Index allocations set forth above, and such securities are weighted in accordance with the methodology of each Sub-Index. Additional information about each Sub-Index is set forth in “Additional Information About the Funds’ Strategies and Risks”. The Underlying Index is rebalanced monthly, and the Fund will generally rebalance in accordance with the Underlying Index. In seeking its investment objective, the Fund will generally invest in fixed income securities included in each Sub-Index, which include: (i) mortgage-backed securities based on pools of 30-year mortgages issued by the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”); (ii) U.S. dollar-denominated bonds that are issued by U.S. companies and are considered investment grade (defined by the Index Provider as those with an average credit rating that is 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); (iii) U.S. dollar-denominated high yield bonds (commonly known as “junk bonds”) and bonds with the lowest credit rating considered investment grade, defined by the Index Provider as those that have an average credit rating that is higher than B- and lower than or equal to BBB- (or equivalent) by S&P, Fitch or Moody’s; and (iv) U.S. dollar-denominated bonds have an average credit rating that is higher than B- (or equivalent) by S&P, Fitch or Moody’s issued by sovereign governments, and agencies thereof, of countries that the Index Provider considers to be “emerging market countries” (as of August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, Malaysia, Mexico, Morocco, Peru, the Philippines, Poland, Russia, South Africa, Taiwan, Thailand, Turkey, the United Arab Emirates and Vietnam). The Fund also may invest in securities issued in accordance with Rule 144A (“Rule 144A securities”) and Regulation S (“Regulation S securities”) under the Securities Act of 1933, as amended (the “Securities Act”). Transactions in U.S. government agency mortgage-backed securities may occur through standardized agreements for forward or future delivery in which the actual mortgage pools to be delivered are not specified until shortly prior to settlement (to be announced (“TBA”) transactions). The Fund may engage in such TBA transactions. As of August 31, 2019, the Underlying Index was comprised of 825 constituents. 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. A “sampling” methodology means that the Adviser uses a quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that have, in the aggregate, investment characteristics similar to the Underlying Index in terms of key risk factors, performance attributes and other characteristics. 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. 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 changes to 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 Investment Risk. Investments in the securities of issuers in emerging market countries involve risks often not associated with investments in the securities of issuers in developed countries. Securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets. Fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in emerging market securities, and emerging market securities may have relatively low market liquidity, decreased publicly available 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. Emerging market securities also are subject to the risks of expropriation, nationalization or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in emerging market securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions. Emerging markets usually are subject to greater market volatility, lower trading volume, political and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Securities law in many emerging market countries is relatively new and unsettled. Therefore, laws regarding foreign investment in emerging market securities, securities regulation, title to securities, and shareholder rights may change quickly and unpredictably. In addition, the enforcement of systems of taxation at federal, regional and local levels in emerging market countries may be inconsistent and subject to sudden change. 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 Fixed-Income Investment Risk. Investments in fixed income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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. 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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. 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. In addition, TBA transactions involve the risk that the securities received may be less favorable than what was anticipated by the Fund when entering into the TBA transaction, as well as counterparty risk. Default or bankruptcy of a counterparty to a TBA transaction would expose the Fund to potential loss and could affect the Fund’s returns. 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 and unrated securities of comparable credit quality are considered speculative and 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. 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.

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 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 other indexes and is comprised of component securities of such indexes (each, a “Sub-Index”). The Underlying Index weights the components of the following Sub-Indexes according to the following corresponding fixed, target weightings: (i) Invesco U.S. Treasury 1-3 Years Index (55% weight); (ii) Invesco U.S. Fixed Rate 30-Year MBS Index (20% weight); (iii) Invesco Investment Grade Defensive Index (15% weight); and (iv) Invesco Emerging Markets Debt Defensive Index (10% weight). The Underlying Index will typically include between 200-500 securities. The securities in the Underlying Index are weighted pursuant to the Sub-Index allocations set forth above, and such securities are weighted in accordance with the methodology of each Sub-Index. Additional information about each Sub-Index is set forth in “Additional Information About the Funds’ Strategies and Risks”. The Underlying Index is rebalanced monthly, and the Fund will generally rebalance in accordance with the Underlying Index. In seeking its investment objective, the Fund will generally invest in fixed income securities included each Sub-Index, which include: (i) U.S. dollar-denominated Treasury securities with maturities from 1 year up to 3 years, regardless of call features; (ii) mortgage-backed securities based on pools of 30-year mortgages issued by the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”); (iii) U.S. dollar-denominated bonds that are issued by U.S. companies and are considered investment grade (defined by the Index Provider as those with an average credit rating that is 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); and (iv) U.S. dollar-denominated bonds rated higher than B- (or equivalent) by S&P, Fitch or Moody’s that are issued by sovereign governments, and agencies thereof, of countries that the Index Provider considers to be “emerging market countries” (as of August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, Malaysia, Mexico, Morocco, Peru, the Philippines, Poland, Russia, South Africa, Taiwan, Thailand, Turkey, the United Arab Emirates and Vietnam). The Fund also may invest in securities issued in accordance with Rule 144A (“Rule 144A securities”) and Regulation S (“Regulation S securities”) under the Securities Act of 1933, as amended (the “Securities Act”). Transactions in U.S. government agency mortgage-backed securities may occur through standardized agreements for forward or future delivery in which the actual mortgage pools to be delivered are not specified until shortly prior to settlement (to be announced (“TBA”) transactions). The Fund may engage in such TBA transactions. As of August 31, 2019, the Underlying Index was comprised of 361 constituents. 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. A “sampling” methodology means that the Adviser uses a quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that have, in the aggregate, investment characteristics similar to the Underlying Index in terms of key risk factors, performance attributes and other characteristics. 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.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. 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 changes to 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 Investment Risk. Investments in the securities of issuers in emerging market countries involve risks often not associated with investments in the securities of issuers in developed countries. Securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets. Fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in emerging market securities, and emerging market securities may have relatively low market liquidity, decreased publicly available 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. Emerging market securities also are subject to the risks of expropriation, nationalization or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in emerging market securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions. Emerging markets usually are subject to greater market volatility, lower trading volume, political and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Securities law in many emerging market countries is relatively new and unsettled. Therefore, laws regarding foreign investment in emerging market securities, securities regulation, title to securities, and shareholder rights may change quickly and unpredictably. In addition, the enforcement of systems of taxation at federal, regional and local levels in emerging market countries may be inconsistent and subject to sudden change. 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 Fixed-Income Investment Risk. Investments in fixed income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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. 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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. Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares, or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. 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. In addition, TBA transactions involve the risk that the securities received may be less favorable than what was anticipated by the Fund when entering into the TBA transaction, as well as counterparty risk. Default or bankruptcy of a counterparty to a TBA transaction would expose the Fund to potential loss and could affect the Fund’s returns. 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 and unrated securities of comparable credit quality are considered speculative and 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. 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.

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 4% of the average value of its portfolio.

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:

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated investment grade corporate bonds with maturities or, in some cases, “effective maturities” in the year 2026 (collectively, “2026 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) be rated at least BBB- by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or at least Baa3 by Moody’s Investors Service, Inc. (“Moody’s”); and (iii) have at least $500 million in face value outstanding (existing bonds in the eligible universe require $400 million in face value outstanding to remain eligible).

2026 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 243 constituents.

The Fund will terminate on or about December 15, 2026. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2026), no new constituents are added and the Underlying Index rebalances only through June. In the last six months of operation, when the 2026 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2026 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates, are likely to change over time.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Sampling Risk. The Fund’s use of a representative sampling approach may 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.

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 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.

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 and American depositary receipts (“ADRs”) and global depositary receipts (“GDRs”) that are based on securities in 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 measure the performance of equity securities issued by higher quality, large-business-sized companies located in countries designated as developed market countries (excluding the U.S.). 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 Index Provider selects components for inclusion in the Underlying Index from an investment universe of foreign equity securities with at least one year of trading history, issued by companies located in countries designated as developed market countries (excluding the U.S.). Each eligible equity security is assigned a business-size score (“Business-Size Score”) based on the equally-weighted average of the following four factors of company size over the prior five years (or, if shorter, the life of the security): sales, operating cash flow, total return of capital (dividends and share repurchases) and book value. For real estate securities (real estate investment trusts (“REITs”) and common stocks of companies in the real estate sector), operating cash flow is replaced by funds from operations and book value is replaced by total assets. Each eligible security is then assigned a quality score (“Quality Score”) based on the equally-weighted average of the following two quality factors: efficiency (calculated as the ratio of sales-to-assets in the prior year) and growth (calculated as the percentage change in the ratio of sales-to-assets over the prior five years (or, if shorter, the life of the security)). Each eligible security is ranked in descending order by its Business-Size Score. Those securities in the top 90% by Business-Size Score are eligible for inclusion in the Underlying Index and, of those, the 80% with the highest Quality Scores are included in the Underlying Index. Securities in the Underlying Index are weighted based on their float-adjusted Business-Size Scores.   As of August 31, 2019, the following countries were classified as developed markets (excluding the U.S.) by the Index Provider: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, Luxembourg, the Netherlands, New Zealand, Norway, Portugal, Singapore, South Korea, Spain, Sweden, Switzerland, and United Kingdom. As of August 31, 2019, the Underlying Index was comprised of 795 constituents. The Fund employs a “full replication” methodology in seeking to track the Underlying Index, meaning that the Fund generally invests in all of the securities comprising the Underlying Index in proportion to their weightings in the Underlying Index. 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. ADR and GDR Risk. ADRs are certificates that evidence ownership of shares of a foreign issuer and are alternatives to purchasing the underlying foreign securities directly in their national markets and currencies. GDRs are certificates issued by an international bank that generally are traded and denominated in the currencies of countries other than the home country of the issuer of the underlying shares. ADRs and GDRs may be subject to certain of the risks associated with direct investments in the securities of foreign companies, such as currency, political, economic and market risks, because their values depend on the performance of the non-dollar denominated underlying foreign securities. Moreover, ADRs and GDRs may not track the price of the underlying foreign securities on which they are based, and their value may change materially at times when U.S. markets are not open for trading. 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar. Generally, an increase in the value of the U.S. dollar against a foreign currency will reduce the value of a security denominated in that foreign currency, thereby decreasing the Fund’s overall NAV. Exchange rates may be volatile and may change quickly and unpredictably in response to both global economic developments and economic conditions, causing an adverse impact on the Fund. As a result, investors have the potential for losses regardless of the length of time they intend to hold Shares. Equity Risk. Equity risk is the risk that the value of equity securities, including common stocks, may fall due to both changes in general economic conditions that impact the market as a whole, as well as factors that directly relate to a specific company or its industry. Such general economic conditions include changes in interest rates, periods of market turbulence or instability, or general and prolonged periods of economic decline and cyclical change. It is possible that a drop in the stock market may depress the price of most or all of the common stocks that the Fund holds. In addition, equity risk includes the risk that investor sentiment toward one or more industries will become negative, resulting in those investors exiting their investments in those industries, which could cause a reduction in the value of companies in those industries more broadly. The value of a company’s common stock may fall solely because of factors, such as an increase in production costs, that negatively impact other companies in the same region, industry or sector of the market. A company’s common stock also may decline significantly in price over a short period of time due to factors specific to that company, including decisions made by its management or lower demand for the company’s products or services. For example, an adverse event, such as an unfavorable earnings report or the failure to make anticipated dividend payments, may depress the value of common stock. 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. As the Fund will invest in securities denominated in foreign currencies, fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in foreign securities and may negatively impact the Fund’s returns. Geographic Concentration Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in that specific geographic region and adversely impact the Fund’s investments in the affected region. 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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. 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. Mid-Capitalization Company Risk. Investing in securities of mid-capitalization companies involves greater risk than is customarily associated with investing in larger, more established companies. These companies’ securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often mid-capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. 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. 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. REIT Risk. REITs are subject to risks inherent in the direct ownership of real estate. These risks include, but are not limited to, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. REITs may be affected by changes in the values of the underlying properties that they own or operate and could fail to qualify for favorable tax or regulatory treatment. REITs also are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs rely heavily on cash flows and a variety of economic and other factors may adversely affect a lessee’s ability to meet its obligations to a REIT. Should a lessee default on their loan, the REIT may experience delays in enforcing its rights as a lessor and may incur substantial costs associated in protecting its investments. 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 securities and, because foreign exchanges may be open on days when the Fund does not price its Shares, the value of those 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 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.

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 measure the performance of equity securities issued by higher quality, small-business-sized companies designated as U.S. companies. 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 Index Provider selects components for inclusion in the Underlying Index from an investment universe of domestic equity securities with at least one year of trading history. Each eligible equity security is assigned a business-size score (“Business-Size Score”) based on the equally-weighted average of the following four factors of company size over the prior five years (or, if shorter, the life of the security): sales, operating cash flow, total return of capital (dividends and share repurchases) and book value. For real estate securities (real estate investment trusts (“REITs”) and common stocks of companies in the real estate sector), operating cash flow is replaced by funds from operations and book value is replaced by total assets. Each eligible security is then assigned a quality score (“Quality Score”) based on the equally-weighted average of the following two quality factors of its company’s business: efficiency (calculated as the ratio of sales-to-assets in the prior year) and growth (calculated as the percentage change in the ratio of sales-to-assets over the prior five years (or, if shorter, the life of the security)). Each eligible security is ranked in descending order by its Business-Size Score. Those securities ranked below 90% by Business-Size Score are eligible for inclusion in the Underlying Index and, of those, the 80% with the highest Quality Scores are included in the Underlying Index. Securities in the Underlying Index are weighted based on their float-adjusted Business-Size Scores. As of August 31, 2019, the Underlying Index was comprised of 1,216 constituents. The Fund employs a “full replication” methodology in seeking to track the Underlying Index, meaning that the Fund generally invests in all of the securities comprising the Underlying Index in proportion to their weightings in the Underlying Index. 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. Equity Risk. Equity risk is the risk that the value of equity securities, including common stocks, may fall due to both changes in general economic conditions that impact the market as a whole, as well as factors that directly relate to a specific company or its industry. Such general economic conditions include changes in interest rates, periods of market turbulence or instability, or general and prolonged periods of economic decline and cyclical change. It is possible that a drop in the stock market may depress the price of most or all of the common stocks that the Fund holds. In addition, equity risk includes the risk that investor sentiment toward one or more industries will become negative, resulting in those investors exiting their investments in those industries, which could cause a reduction in the value of companies in those industries more broadly. The value of a company’s common stock may fall solely because of factors, such as an increase in production costs, that negatively impact other companies in the same region, industry or sector of the market. A company’s common stock also may decline significantly in price over a short period of time due to factors specific to that company, including decisions made by its management or lower demand for the company’s products or services. For example, an adverse event, such as an unfavorable earnings report or the failure to make anticipated dividend payments, may depress the value of common stock. 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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. Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares, or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. 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. 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. REIT Risk. REITs are subject to risks inherent in the direct ownership of real estate. These risks include, but are not limited to, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. REITs may be affected by changes in the values of the underlying properties that they own or operate and could fail to qualify for favorable tax or regulatory treatment. REITs also are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs rely heavily on cash flows and a variety of economic and other factors may adversely affect a lessee’s ability to meet its obligations to a REIT. Should a lessee default on their loan, the REIT may experience delays in enforcing its rights as a lessor and may incur substantial costs associated in protecting its investments. Small- and Mid-Capitalization Company Risk. Investing in securities of small- and mid-capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies’ securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small- and mid-capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions.

These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 19% of the average value of its portfolio.

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated high yield corporate bonds (commonly known as “junk bonds”) with maturities or, in some cases, “effective maturities” in the year 2023 (collectively, “2023 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) have a maximum rating of BB+ from S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or a maximum rating of Ba1 from Moody’s Investors Service, Inc. (“Moody’s”); (iii) have a minimum average credit rating (computed by calculating the simple average of a bond’s rating published by S&P, Fitch and Moody’s and then rounding down to the nearest rating step) of CCC- from S&P, Fitch and Moody’s; and (iv) have at least $200 million in face value outstanding (existing bonds in the eligible universe require $150 million in face value outstanding to remain eligible).

The eligible universe may include securities issued in accordance with Rule 144A under the Securities Act of 1933, as amended (“Securities Act”).

2023 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 207 constituents.

The Fund will terminate on or about December 15, 2023. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2023), no new constituents are added and the Underlying Index does not rebalance. In the last twelve months of operation, when the 2023 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2023 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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 may 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.

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.

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 BulletShares 2025 Corporate Bond ETF

Invesco BulletShares 2025 Corporate Bond ETF Summary Information

Investment Objective

The Invesco BulletShares 2025 Corporate Bond ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Nasdaq BulletShares^® USD Corporate Bond 2025 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 BulletShares 2025 Corporate Bond ETF Invesco BulletShares 2025 Corporate Bond ETF
Management Fees	0.10%
Other Expenses	none
Total Annual Fund Operating Expenses	0.10%

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	5 Years	10 Years
Invesco BulletShares 2025 Corporate Bond ETF | Invesco BulletShares 2025 Corporate Bond ETF | USD ($)	10	32	57	128

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 3% of the average value of its portfolio.

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.

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 seeks to measure the performance of a portfolio of U.S. dollar-denominated investment grade corporate bonds with maturities or, in some cases, “effective maturities” in the year 2025 (collectively, “2025 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) be rated at least BBB- by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or at least Baa3 by Moody’s Investors Service, Inc. (“Moody’s”); and (iii) have at least $500 million in face value outstanding (existing bonds in the eligible universe require $400 million in face value outstanding to remain eligible).

2025 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 234 constituents.

The Fund will terminate on or about December 15, 2025. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2025), no new constituents are added and the Underlying Index rebalances only through June. In the last six months of operation, when the 2025 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2025 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates, 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Sampling Risk. The Fund’s use of a representative sampling approach may 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.

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

The bar chart below shows how the Fund has performed. The table below the bar chart shows the Fund’s average annual total returns (before and after taxes). The bar chart and table provide an indication of the risks of investing in the Fund by showing how the Fund’s total returns have varied from year to year and by showing how the Fund’s average annual total returns compared with a broad measure of market performance and an additional index with characteristics relevant to the Fund. Although the information shown in the bar chart and the table gives you some idea of the risks involved in investing in the Fund, the Fund’s past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future.

The Fund is the successor to the investment performance of the Guggenheim BulletShares 2025 Corporate Bond ETF (the “Predecessor Fund”) as a result of the reorganization of the Predecessor Fund into the Fund, which was consummated after the close of business on April 6, 2018. Accordingly, the performance information shown below for periods ending on or prior to April 6, 2018 is that of the Predecessor Fund.

Invesco Multi-Factor Defensive Core Fixed Income ETF

Invesco Multi-Factor Defensive Core Fixed Income ETF Summary Information

Investment Objective

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

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 Defensive Core Fixed Income ETF Invesco Multi-Factor Defensive Core Fixed Income ETF
Management Fees	0.12%
Other Expenses	none	[1]
Total Annual Fund Operating Expenses	0.12%

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	5 Years	10 Years
Invesco Multi-Factor Defensive Core Fixed Income ETF | Invesco Multi-Factor Defensive Core Fixed Income ETF | USD ($)	12	39	68	154

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.

During the fiscal period December 4, 2018 (commencement of operations) through August 31, 2019, the Fund’s portfolio turnover rate was 52% of the average value of its portfolio.

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 other indexes and is comprised of component securities of such indexes (each, a “Sub-Index”). The Underlying Index weights the components of the following Sub-Indexes according to the following corresponding fixed, target weightings: (i) Invesco U.S. Treasury 1-3 Years Index (55% weight); (ii) Invesco U.S. Fixed Rate 30-Year MBS Index (20% weight); (iii) Invesco Investment Grade Defensive Index (15% weight); and (iv) Invesco Emerging Markets Debt Defensive Index (10% weight). The Underlying Index will typically include between 200-500 securities. The securities in the Underlying Index are weighted pursuant to the Sub-Index allocations set forth above, and such securities are weighted in accordance with the methodology of each Sub-Index. Additional information about each Sub-Index is set forth in “Additional Information About the Funds’ Strategies and Risks”. The Underlying Index is rebalanced monthly, and the Fund will generally rebalance in accordance with the Underlying Index.

In seeking its investment objective, the Fund will generally invest in fixed income securities included each Sub-Index, which include: (i) U.S. dollar-denominated Treasury securities with maturities from 1 year up to 3 years, regardless of call features; (ii) mortgage-backed securities based on pools of 30-year mortgages issued by the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”); (iii) U.S. dollar-denominated bonds that are issued by U.S. companies and are considered investment grade (defined by the Index Provider as those with an average credit rating that is 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); and (iv) U.S. dollar-denominated bonds rated higher than B- (or equivalent) by S&P, Fitch or Moody’s that are issued by sovereign governments, and agencies thereof, of countries that the Index Provider considers to be “emerging market countries” (as of August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, Malaysia, Mexico, Morocco, Peru, the Philippines, Poland, Russia, South Africa, Taiwan, Thailand, Turkey, the United Arab Emirates and Vietnam). The Fund also may invest in securities issued in accordance with Rule 144A (“Rule 144A securities”) and Regulation S (“Regulation S securities”) under the Securities Act of 1933, as amended (the “Securities Act”). Transactions in U.S. government agency mortgage-backed securities may occur through standardized agreements for forward or future delivery in which the actual mortgage pools to be delivered are not specified until shortly prior to settlement (to be announced (“TBA”) transactions). The Fund may engage in such TBA transactions.

As of August 31, 2019, the Underlying Index was comprised of 361 constituents.

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. A “sampling” methodology means that the Adviser uses a quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that have, in the aggregate, investment characteristics similar to the Underlying Index in terms of key risk factors, performance attributes and other characteristics.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 changes to 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 Investment Risk. Investments in the securities of issuers in emerging market countries involve risks often not associated with investments in the securities of issuers in developed countries. Securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets. Fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in emerging market securities, and emerging market securities may have relatively low market liquidity, decreased publicly available 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. Emerging market securities also are subject to the risks of expropriation, nationalization or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in emerging market securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions. Emerging markets usually are subject to greater market volatility, lower trading volume, political and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Securities law in many emerging market countries is relatively new and unsettled. Therefore, laws regarding foreign investment in emerging market securities, securities regulation, title to securities, and shareholder rights may change quickly and unpredictably. In addition, the enforcement of systems of taxation at federal, regional and local levels in emerging market countries may be inconsistent and subject to sudden change.

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 Fixed-Income Investment Risk. Investments in fixed income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares, or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns.

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. In addition, TBA transactions involve the risk that the securities received may be less favorable than what was anticipated by the Fund when entering into the TBA transaction, as well as counterparty risk. Default or bankruptcy of a counterparty to a TBA transaction would expose the Fund to potential loss and could affect the Fund’s returns.

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 and unrated securities of comparable credit quality are considered speculative and 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

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.

Performance

The Fund commenced operations on December 4, 2018 and therefore does not yet have a full calendar year of performance history. Once the Fund has a full calendar year of performance information, the Fund will present total return information, which is also accessible on the Fund’s website at www.invesco.com/ETFs and provides some indication of the risks of investing in the Fund.

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) have an average credit rating that is 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 in face value 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 new eligible security with a Quality Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index constituents with a Quality Score in the top 50% of eligible securities remain in the Underlying Index provided that they satisfy all other eligibility criteria. Underlying Index constituents are equally weighted. As of August 31, 2019, the Underlying Index was comprised of 113 constituents. 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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates its investments, 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. 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 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole. Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies. 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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, 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 August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, 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) have an average credit rating that is 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 in face value 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 bond type 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 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 new eligible security with a QAV Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index constituents with a QAV Score in the top 60% of eligible securities remain in the Underlying Index provided that they satisfy all other eligibility criteria. Underlying Index constituents are modified market-value weighted.   As of August 31, 2019, the Underlying Index was comprised of 160 constituents. 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. 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 Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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. 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. Privately-Issued Securities Risk. The Fund may invest in privately-issued securities, including those that are normally purchased or resold pursuant to 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. As such Rule 144A and Regulation S securities may be subject to legal restrictions on resale. Privately-issued securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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. 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.

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.

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 seeks to measure the performance of a portfolio of U.S. dollar-denominated investment grade corporate bonds with maturities or, in some cases, “effective maturities” in the year 2021 (collectively, “2021 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) be rated at least BBB- by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or at least Baa3 by Moody’s Investors Service, Inc. (“Moody’s”); and (iii) have at least $500 million in face value outstanding (existing bonds in the eligible universe require $400 million in face value outstanding to remain eligible).

2021 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 391 constituents.

The Fund will terminate on or about December 15, 2021. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2021), no new constituents are added and the Underlying Index rebalances only through June. In the last six months of operation, when the 2021 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2021 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates, are likely to change over time.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Sampling Risk. The Fund’s use of a representative sampling approach may 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.

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.

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.

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 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 August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, 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) have an average credit rating that is 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 in face value 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 new eligible security with a Quality Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index constituents with a Quality Score in the top 60% of eligible securities remain in the Underlying Index provided that they satisfy all other eligibility criteria. Underlying Index constituents are modified market-value weighted.   As of August 31, 2019, the Underlying Index was comprised of 103 constituents. 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.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. 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 Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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. 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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. Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. Portfolio Turnover Risk. The Fund may engage in frequent trading of its portfolio securities in connection with the rebalancing or adjustment of the Underlying Index. A portfolio turnover rate of 200%, for example, is equivalent to the Fund buying and selling all of its securities two times during the course of a year. A high portfolio turnover rate (such as 100% or more) could result in high brokerage costs for the Fund. Privately-Issued Securities Risk. The Fund may invest in privately-issued securities, including those that are normally purchased or resold pursuant to 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. As such Rule 144A and Regulation S securities may be subject to legal restrictions on resale. Privately-issued securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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 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 BulletShares 2026 High Yield Corporate Bond ETF

Invesco BulletShares 2026 High Yield Corporate Bond ETF Summary Information

Investment Objective

The Invesco BulletShares 2026 High Yield Corporate Bond ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Nasdaq BulletShares^® USD High Yield Corporate Bond 2026 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 BulletShares 2026 High Yield Corporate Bond ETF Invesco BulletShares 2026 High Yield Corporate Bond ETF
Management Fees	0.42%
Other Expenses	none	[1]
Total Annual Fund Operating Expenses	0.42%

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	5 Years	10 Years
Invesco BulletShares 2026 High Yield Corporate Bond ETF | Invesco BulletShares 2026 High Yield Corporate Bond ETF | USD ($)	43	135	235	530

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. During the most recent fiscal year, the portfolio turnover rate of the Fund was 48% of the average value of its portfolio.

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated high yield corporate bonds (commonly known as “junk bonds”) with maturities or, in some cases, “effective maturities” in the year 2026 (collectively, “2026 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) have a maximum rating of BB+ from S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or a maximum rating of Ba1 from Moody’s Investors Service, Inc. (“Moody’s”); (iii) have a minimum average credit rating (computed by calculating the simple average of a bond’s rating published by S&P, Fitch and Moody’s and then rounding down to the nearest rating step) of CCC- from S&P, Fitch and Moody’s; and (iv) have at least $200 million in face value outstanding (existing bonds in the eligible universe require $150 million in face value outstanding to remain eligible).

The eligible universe may include securities issued in accordance with Rule 144A under the Securities Act of 1933, as amended (“Securities Act”).

2026 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance.

Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 154 constituents.

The Fund will terminate on or about December 15, 2026. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2026), no new constituents are added and the Underlying Index does not rebalance. In the last twelve months of operation, when the 2026 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2026 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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 may 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.

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.

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 1% of the average value of its portfolio.

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated investment grade corporate bonds with maturities or, in some cases, “effective maturities” in the year 2028 (collectively, “2028 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) be rated at least BBB- by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or at least Baa3 by Moody’s Investors Service, Inc. (“Moody’s”); and (iii) have at least $500 million in face value outstanding (existing bonds in the eligible universe require $400 million in face value outstanding to remain eligible).

2028 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance.

Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 145 constituents.

The Fund will terminate on or about December 15, 2028. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2028), no new constituents are added and the Underlying Index rebalances only through June. In the last six months of operation, when the 2028 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2028 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Sampling Risk. The Fund’s use of a representative sampling approach may 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.

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.

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated investment grade corporate bonds with maturities or, in some cases, “effective maturities” in the year 2023 (collectively, “2023 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) be rated at least BBB- by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or at least Baa3 by Moody’s Investors Service, Inc. (“Moody’s”); and (iii) have at least $500 million in face value outstanding (existing bonds in the eligible universe require $400 million in face value outstanding to remain eligible).

2023 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 313 constituents.

The Fund will terminate on or about December 15, 2023. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2023), no new constituents are added and the Underlying Index rebalances only through June. In the last six months of operation, when the 2023 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2023 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates, are likely to change over time.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Sampling Risk. The Fund’s use of a representative sampling approach may 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.

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.

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.

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 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. As of August 31, 2019, the Underlying Index was comprised of 716 constituents. 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. corporate bonds having the highest “quality scores” within an eligible universe of U.S. high yield bonds (commonly known as “junk bonds”) and bonds with the lowest credit rating considered investment grade, all 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) have an average credit rating that is higher than B- and lower than or equal to 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 in face value 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 new eligible security with a Quality Score in the top 30% of eligible securities is added to the HY Defensive Index, and current constituents with a Quality Score in the top 50% of eligible securities remain in the HY Defensive Index provided that they satisfy all other eligibility criteria. HY Defensive Index constituents 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) have an average credit rating that is higher than BBB- (or equivalent) by S&P, Fitch, or Moody’s credit rating agencies; (ii) have at least $600 million in face value 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 new eligible security with a Quality Score in the top 30% of eligible securities is added to the IG Defensive Index, and current constituents with a Quality Score in the top 50% of eligible securities remain in the IG Defensive Index provided that they satisfy all other eligibility criteria. IG Defensive Index constituents 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 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 includes 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. Transactions in U.S. government agency mortgage-backed securities may occur through standardized agreements for forward or future delivery in which the actual mortgage pools to be delivered are not specified until shortly prior to settlement (to be announced (“TBA”) transactions). The Fund may engage in such TBA transactions. 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 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 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) have an average credit rating that is higher than BBB- (or equivalent) by S&P, Fitch, or Moody’s credit rating agencies; (ii) have at least $600 million in face value 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 quality adjusted value (“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 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 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 new eligible security with a QAV Score in the top 30% of eligible securities is added to the IG Value Index, and current constituents with a QAV Score in the top 50% of eligible securities remain in the IG Value Index provided that they satisfy all other eligibility criteria. IG Value Index constituents 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 the Index Provider considers to be “emerging market countries” (as of August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, 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) have an average credit rating that is higher than B- (or equivalent) by S&P, Fitch or Moody’s credit rating agencies; (ii) have at least $500 million in face value 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 new eligible security with a Quality Score in the top 30% of eligible securities is added to the EM Debt Defensive Index, and current constituents with a Quality Score in the top 60% of eligible securities remain in the EM Debt Defensive Index provided that they satisfy all other eligibility criteria. EM Debt Defensive Index constituents are modified market-value weighted. Invesco Emerging Markets Debt Value Index. The Invesco Emerging Markets Debt Value Index (the “EM Debt Value Index”) 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 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 the Index Provider considers to be “emerging market countries” (as of August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, 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) have an average credit rating that is higher than B- (or equivalent) by S&P, Fitch or Moody’s credit rating agencies; (ii) have at least $500 million in face value 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 category, then the Value Score for all bonds in the grouping is replaced with the percentile rank based on bond type 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 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 new eligible security with a QAV Score in the top 30% of eligible securities is added to the EM Debt Value Index, and current constituents with a QAV Score in the top 60% of eligible securities remain in the EM Debt Value Index provided that they satisfy all other eligibility criteria. EM Debt Value Index constituents 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. 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 changes to 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. 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 Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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. 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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. In addition, TBA transactions involve the risk that the securities received may be less favorable than what was anticipated by the Fund when entering into the TBA transaction and counterparty risk. Default or bankruptcy of a counterparty to a TBA transaction would expose the Fund to potential loss and could affect the Fund’s returns. 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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 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 BulletShares 2021 Corporate Bond ETF

Invesco BulletShares 2021 Corporate Bond ETF Summary Information

Investment Objective

The Invesco BulletShares 2021 Corporate Bond ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Nasdaq BulletShares^® USD Corporate Bond 2021 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 BulletShares 2021 Corporate Bond ETF Invesco BulletShares 2021 Corporate Bond ETF
Management Fees	0.10%
Other Expenses	none
Total Annual Fund Operating Expenses	0.10%

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	5 Years	10 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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 6% of the average value of its portfolio.

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.

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 seeks to measure the performance of a portfolio of U.S. dollar-denominated investment grade corporate bonds with maturities or, in some cases, “effective maturities” in the year 2021 (collectively, “2021 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) be rated at least BBB- by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or at least Baa3 by Moody’s Investors Service, Inc. (“Moody’s”); and (iii) have at least $500 million in face value outstanding (existing bonds in the eligible universe require $400 million in face value outstanding to remain eligible).

2021 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 391 constituents.

The Fund will terminate on or about December 15, 2021. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2021), no new constituents are added and the Underlying Index rebalances only through June. In the last six months of operation, when the 2021 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2021 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates, 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Sampling Risk. The Fund’s use of a representative sampling approach may 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.

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

The bar chart below shows how the Fund has performed. The table below the bar chart shows the Fund’s average annual total returns (before and after taxes). The bar chart and table provide an indication of the risks of investing in the Fund by showing how the Fund’s total returns have varied from year to year and by showing how the Fund’s average annual total returns compared with a broad measure of market performance and an additional index with characteristics relevant to the Fund. Although the information shown in the bar chart and the table gives you some idea of the risks involved in investing in the Fund, the Fund’s past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future.

The Fund is the successor to the investment performance of the Guggenheim BulletShares 2021 Corporate Bond ETF (the “Predecessor Fund”) as a result of the reorganization of the Predecessor Fund into the Fund, which was consummated after the close of business on April 6, 2018. Accordingly, the performance information shown below for periods ending on or prior to April 6, 2018 is that of the Predecessor Fund.

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 4% of the average value of its portfolio.

Strategy [Heading]

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.

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 seeks to measure the performance of a portfolio of U.S. dollar-denominated investment grade corporate bonds with maturities or, in some cases, “effective maturities” in the year 2022 (collectively, “2022 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) be rated at least BBB- by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or at least Baa3 by Moody’s Investors Service, Inc. (“Moody’s”); and (iii) have at least $500 million in face value outstanding (existing bonds in the eligible universe require $400 million in face value outstanding to remain eligible).

2022 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 375 constituents.

The Fund will terminate on or about December 15, 2022. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2022), no new constituents are added and the Underlying Index rebalances only through June. In the last six months of operation, when the 2022 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2022 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates, are likely to change over time.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Sampling Risk. The Fund’s use of a representative sampling approach may 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.

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 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.

Portfolio Turnover

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 27% of the average value of its portfolio.

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:

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated high yield corporate bonds (commonly known as “junk bonds”) with maturities or, in some cases, “effective maturities” in the year 2022 (collectively, “2022 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) have a maximum rating of BB+ from S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or a maximum rating of Ba1 from Moody’s Investors Service, Inc. (“Moody’s”); (iii) have a minimum average credit rating (computed by calculating the simple average of a bond’s rating published by S&P, Fitch and Moody’s and then rounding down to the nearest rating step) of CCC- from S&P, Fitch and Moody’s; and (iv) have at least $200 million in face value outstanding (existing bonds in the eligible universe require $150 million in face value outstanding to remain eligible).

The eligible universe may include securities issued in accordance with Rule 144A under the Securities Act of 1933, as amended (“Securities Act”).

2022 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 177 constituents.

The Fund will terminate on or about December 15, 2022. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2022), no new constituents are added and the Underlying Index does not rebalance. In the last twelve months of operation, when the 2022 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2022 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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 may 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.

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.

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 BulletShares 2026 Corporate Bond ETF

Invesco BulletShares 2026 Corporate Bond ETF Summary Information

Investment Objective

The Invesco BulletShares 2026 Corporate Bond ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Nasdaq BulletShares^® USD Corporate Bond 2026 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 BulletShares 2026 Corporate Bond ETF Invesco BulletShares 2026 Corporate Bond ETF
Management Fees	0.10%
Other Expenses	none
Total Annual Fund Operating Expenses	0.10%

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	5 Years	10 Years
Invesco BulletShares 2026 Corporate Bond ETF | Invesco BulletShares 2026 Corporate Bond ETF | USD ($)	10	32	57	128

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 4% of the average value of its portfolio.

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated investment grade corporate bonds with maturities or, in some cases, “effective maturities” in the year 2026 (collectively, “2026 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) be rated at least BBB- by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or at least Baa3 by Moody’s Investors Service, Inc. (“Moody’s”); and (iii) have at least $500 million in face value outstanding (existing bonds in the eligible universe require $400 million in face value outstanding to remain eligible).

2026 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 243 constituents.

The Fund will terminate on or about December 15, 2026. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2026), no new constituents are added and the Underlying Index rebalances only through June. In the last six months of operation, when the 2026 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2026 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates, 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Sampling Risk. The Fund’s use of a representative sampling approach may 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.

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

The bar chart below shows how the Fund has performed. The table below the bar chart shows the Fund’s average annual total returns (before and after taxes). The bar chart and table provide an indication of the risks of investing in the Fund by showing how the Fund’s total returns have varied from year to year and by showing how the Fund’s average annual total returns compared with a broad measure of market performance and an additional index with characteristics relevant to the Fund. Although the information shown in the bar chart and the table gives you some idea of the risks involved in investing in the Fund, the Fund’s past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future.

The Fund is the successor to the investment performance of the Guggenheim BulletShares 2026 Corporate Bond ETF (the “Predecessor Fund”) as a result of the reorganization of the Predecessor Fund into the Fund, which was consummated after the close of business on April 6, 2018. Accordingly, the performance information shown below for periods ending on or prior to April 6, 2018 is that of the Predecessor Fund.

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.

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 seeks to measure the performance of a portfolio of U.S. dollar-denominated investment grade corporate bonds with maturities or, in some cases, “effective maturities” in the year 2024 (collectively, “2024 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) be rated at least BBB- by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or at least Baa3 by Moody’s Investors Service, Inc. (“Moody’s”); and (iii) have at least $500 million in face value outstanding (existing bonds in the eligible universe require $400 million in face value outstanding to remain eligible).

2024 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 244 constituents.

The Fund will terminate on or about December 15, 2024. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2024), no new constituents are added and the Underlying Index rebalances only through June. In the last six months of operation, when the 2024 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2024 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Sampling Risk. The Fund’s use of a representative sampling approach may 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.

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.

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.

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 145% of the average value of its portfolio.

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 the securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, Invesco Indexing LLC (“Invesco Indexing” or the “Index Provider”) compiles and maintains the Underlying Index, which is comprised of a subset of securities from the S&P 500^® Index (the “S&P 500”). 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”).

Instead of the traditional approach to defensive equity portfolios that focuses solely on low beta stocks, the Underlying Index, using a rules-based quantitative approach, is designed to measure the performance of approximately 100 equal-weighted securities selected from the S&P 500 based on (i) the probability of delivering the required revenue growth to support the current stock price, (ii) beta (a measure of a given security’s volatility in relation to the volatility of a specific market) and (iii) down market volatility (a measurement that represents a security’s volatility during adverse market conditions). For each security in the S&P 500, the probability of delivering the required revenue growth to support the current stock price is calculated. The securities in the top 80% based on their probability scores are eligible for inclusion in the Underlying Index. Of those securities, the 75% with the lowest beta are further evaluated and those that rank in the bottom 50% on down market volatility are eligible for inclusion in the Underlying Index. Of those securities, the 100 securities with a higher probability of delivering the required revenue growth to support their current stock prices while minimizing any differences in industry exposure relative to the S&P 500 are included in the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 100 securities with market capitalizations ranging from $5.7 billion to $365.4 billion.

The Fund employs a “full replication” methodology in seeking to track the Underlying Index, meaning that the Fund generally invests in all of the securities comprising the Underlying Index in proportion to their weightings in the Underlying Index.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

Equity Risk. Equity risk is the risk that the value of equity securities, including common stocks, may fall due to both changes in general economic conditions that impact the market as a whole, as well as factors that directly relate to a specific company or its industry. Such general economic conditions include changes in interest rates, periods of market turbulence or instability, or general and prolonged periods of economic decline and cyclical change. It is possible that a drop in the stock market may depress the price of most or all of the common stocks that the Fund holds. In addition, equity risk includes the risk that investor sentiment toward one or more industries will become negative, resulting in those investors exiting their investments in those industries, which could cause a reduction in the value of companies in those industries more broadly. The value of a company’s common stock may fall solely because of factors, such as an increase in production costs, that negatively impact other companies in the same region, industry or sector of the market. A company’s common stock also may decline significantly in price over a short period of time due to factors specific to that company, including decisions made by its management or lower demand for the company’s products or services. For example, an adverse event, such as an unfavorable earnings report or the failure to make anticipated dividend payments, may depress the value of common stock.

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

Industry Concentration Risk. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

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. 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Portfolio Turnover Risk. The Fund may engage in frequent trading of its portfolio securities in connection with the rebalancing or adjustment of the Underlying Index. A portfolio turnover rate of 200%, for example, is equivalent to the Fund buying and selling all of its securities two times during the course of a year. A high portfolio turnover rate (such as 100% or more) could result in high brokerage costs for the Fund. While a high portfolio turnover rate can result in an increase in taxable capital gain distributions to the Fund’s shareholders, the Fund will seek to utilize the in-kind creation and redemption mechanism (described below) to minimize realization of capital gains to the extent possible.

Quantitative Investment Strategy Risk. The factors used in the Underlying Index model’s quantitative analysis and the weight placed on these factors may not accurately predict a security’s value. As a result, the Fund may have a lower return than if the Fund tracked an index based on a fundamental investment strategy, or an index that did not incorporate quantitative analysis.

Invesco RAFI(TM) Strategic Developed ex-US Small Company ETF

Invesco RAFI™ Strategic Developed ex-US Small Company ETF Summary Information

Investment Objective

The Invesco RAFI^TM Strategic Developed ex-US Small Company ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Invesco Strategic Developed ex-US Small Company 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 RAFI(TM) Strategic Developed ex-US Small Company ETF Invesco RAFI(TM) Strategic Developed ex-US Small Company ETF
Management Fees	0.35%
Other Expenses	none	[1]
Total Annual Fund Operating Expenses	0.35%

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	5 Years	10 Years
Invesco RAFI(TM) Strategic Developed ex-US Small Company ETF | Invesco RAFI(TM) Strategic Developed ex-US Small Company ETF | USD ($)	36	113	197	443

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the fiscal period September 10, 2018 (commencement of operations) through August 31, 2019, the Fund’s portfolio turnover rate was 72% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in securities that comprise the Underlying Index and American depositary receipts (“ADRs”) and global depositary receipts (“GDRs”) that are based on securities in 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 measure the performance of equity securities issued by higher quality, small-business-sized companies located in countries designated as developed market countries (excluding the U.S.). 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 Index Provider selects components for inclusion in the Underlying Index from an investment universe of foreign equity securities with at least one year of trading history, issued by companies located in countries designated as developed market countries (excluding the U.S.). Each eligible equity security is assigned a business-size score (“Business-Size Score”) based on the equally-weighted average of the following four factors of company size over the prior five years (or, if shorter, the life of the security): sales, operating cash flow, total return of capital (dividends and share repurchases) and book value. For real estate securities (real estate investment trusts (“REITs”) and common stocks of companies in the real estate sector), operating cash flow is replaced by funds from operations and book value is replaced by total assets.

Each eligible security is then assigned a quality score (“Quality Score”) based on the equally-weighted average of the following two quality factors of its company’s business: efficiency (calculated as the ratio of sales-to assets in the prior year) and growth (calculated as the percentage change in the ratio of sales-to-assets over the prior five years (or, if shorter, the life of the security)).

Each eligible security is ranked in descending order by its Business-Size Score. Those securities ranked below 90% by Business-Size Score are eligible for inclusion in the Underlying Index and, of those, the 80% with the highest Quality Scores are included in the Underlying Index. Securities in the Underlying Index are weighted based on their float-adjusted Business-Size Scores.

As of August 31, 2019, the following countries were classified as developed markets (excluding the U.S.) by the Index Provider: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, Luxembourg, the Netherlands, New Zealand, Norway, Portugal, Singapore, South Korea, Spain, Sweden, Switzerland, and United Kingdom.

As of August 31, 2019, the Underlying Index was comprised of 1,939 constituents.

The Fund employs a “full replication” methodology in seeking to track the Underlying Index, meaning that the Fund generally invests in all of the securities comprising the Underlying Index in proportion to their weightings in the Underlying Index.

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 August 31, 2019, the Fund had significant exposure to the industrials 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.

ADR and GDR Risk. ADRs are certificates that evidence ownership of shares of a foreign issuer and are alternatives to purchasing the underlying foreign securities directly in their national markets and currencies. GDRs are certificates issued by an international bank that generally are traded and denominated in the currencies of countries other than the home country of the issuer of the underlying shares. ADRs and GDRs may be subject to certain of the risks associated with direct investments in the securities of foreign companies, such as currency, political, economic and market risks, because their values depend on the performance of the non-dollar denominated underlying foreign securities. Moreover, ADRs and GDRs may not track the price of the underlying foreign securities on which they are based, and their value may change materially at times when U.S. markets are not open for trading.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar. Generally, an increase in the value of the U.S. dollar against a foreign currency will reduce the value of a security denominated in that foreign currency, thereby decreasing the Fund’s overall NAV. Exchange rates may be volatile and may change quickly and unpredictably in response to both global economic developments and economic conditions, causing an adverse impact on the Fund. As a result, investors have the potential for losses regardless of the length of time they intend to hold Shares.

Equity Risk. Equity risk is the risk that the value of equity securities, including common stocks, may fall due to both changes in general economic conditions that impact the market as a whole, as well as factors that directly relate to a specific company or its industry. Such general economic conditions include changes in interest rates, periods of market turbulence or instability, or general and prolonged periods of economic decline and cyclical change. It is possible that a drop in the stock market may depress the price of most or all of the common stocks that the Fund holds. In addition, equity risk includes the risk that investor sentiment toward one or more industries will become negative, resulting in those investors exiting their investments in those industries, which could cause a reduction in the value of companies in those industries more broadly. The value of a company’s common stock may fall solely because of factors, such as an increase in production costs, that negatively impact other companies in the same region, industry or sector of the market. A company’s common stock also may decline significantly in price over a short period of time due to factors specific to that company, including decisions made by its management or lower demand for the company’s products or services. For example, an adverse event, such as an unfavorable earnings report or the failure to make anticipated dividend payments, may depress the value of common stock.

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. As the Fund will invest in securities denominated in foreign currencies, fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in foreign securities and may negatively impact the Fund’s returns.

Geographic Concentration Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in that specific geographic region and adversely impact the Fund’s investments in the affected region.

Risk of Investing in Japan. The Fund may invest a significant portion of its total assets in securities of issuers from Japan. The growth of Japan’s economy has recently lagged that of its Asian neighbors and other major developed economies. The Japanese economy is heavily dependent on international trade and has been adversely affected by trade tariffs, other protectionist measures, competition from emerging economies and the economic conditions of its trading partners. During the recent global recession, the Japanese economy experienced the effects of the economic slowdown in the United States and Europe. The Japanese economy also faces several other concerns, including a financial system with large levels of nonperforming loans, over-leveraged corporate balance sheets, extensive cross-ownership by major corporations, a changing corporate governance structure, and large government deficits. These issues may cause a continued slowdown of the Japanese economy.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Industrials Sector Risk. Changes in government regulation, world events and economic conditions may adversely affect companies in the industrials sector. In addition, these companies are at risk for environmental and product liability damage claims. Also, commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources, technological developments and labor relations could adversely affect the companies in this sector.

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.

Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares, or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns.

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. 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

REIT Risk. REITs are subject to risks inherent in the direct ownership of real estate. These risks include, but are not limited to, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. REITs may be affected by changes in the values of the underlying properties that they own or operate and could fail to qualify for favorable tax or regulatory treatment. REITs also are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs rely heavily on cash flows and a variety of economic and other factors may adversely affect a lessee’s ability to meet its obligations to a REIT. Should a lessee default on their loan, the REIT may experience delays in enforcing its rights as a lessor and may incur substantial costs associated in protecting its investments.

Small- and Mid-Capitalization Company Risk. Investing in securities of small- and mid-capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies’ securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small- and mid-capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions.

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 securities and, because foreign exchanges may be open on days when the Fund does not price its Shares, the value of those 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 NAV of such Shares.

Performance

The Fund commenced operations on September 10, 2018 and therefore does not have a full calendar year of performance history. Once the Fund has a full calendar year of performance information, the Fund will present total return information, which is also accessible on the Fund’s website at www.invesco.com/ETFs and provides some indication of the risks of investing in the Fund.

[1] Other Expenses do not reflect any extraordinary expenses during the most recent fiscal period, such as the costs associated with a proxy statement of the Fund. Had these expenses been included, Other Expenses would have been 0.05%.

Invesco BulletShares 2027 Corporate Bond ETF

Invesco BulletShares 2027 Corporate Bond ETF Summary Information

Investment Objective

The Invesco BulletShares 2027 Corporate Bond ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Nasdaq BulletShares^® USD Corporate Bond 2027 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 BulletShares 2027 Corporate Bond ETF Invesco BulletShares 2027 Corporate Bond ETF
Management Fees	0.10%
Other Expenses	none	[1]
Total Annual Fund Operating Expenses	0.10%

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	5 Years	10 Years
Invesco BulletShares 2027 Corporate Bond ETF | Invesco BulletShares 2027 Corporate Bond ETF | USD ($)	10	32	57	128

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 3% of the average value of its portfolio.

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.

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 seeks to measure the performance of a portfolio of U.S. dollar-denominated investment grade corporate bonds with maturities or, in some cases, “effective maturities” in the year 2027 (collectively, “2027 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) be rated at least BBB- by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or at least Baa3 by Moody’s Investors Service, Inc. (“Moody’s”); and (iii) have at least $500 million in face value outstanding (existing bonds in the eligible universe require $400 million in face value outstanding to remain eligible).

2027 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 211 constituents.

The Fund will terminate on or about December 15, 2027. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2027), no new constituents are added and the Underlying Index rebalances only through June. In the last six months of operation, when the 2027 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2027 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates, 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Sampling Risk. The Fund’s use of a representative sampling approach may 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.

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 BulletShares 2024 High Yield Corporate Bond ETF

Invesco BulletShares 2024 High Yield Corporate Bond ETF Summary Information

Investment Objective

The Invesco BulletShares 2024 High Yield Corporate Bond ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Nasdaq BulletShares^® USD High Yield Corporate Bond 2024 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 BulletShares 2024 High Yield Corporate Bond ETF Invesco BulletShares 2024 High Yield Corporate Bond ETF
Management Fees	0.42%
Other Expenses	none	[1]
Total Annual Fund Operating Expenses	0.42%

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	5 Years	10 Years
Invesco BulletShares 2024 High Yield Corporate Bond ETF | Invesco BulletShares 2024 High Yield Corporate Bond ETF | USD ($)	43	135	235	530

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 22% of the average value of its portfolio.

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated high yield corporate bonds (commonly known as “junk bonds”) with maturities or, in some cases, “effective maturities” in the year 2024 (collectively, “2024 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) have a maximum rating of BB+ from S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or a maximum rating of Ba1 from Moody’s Investors Service, Inc. (“Moody’s”); (iii) have a minimum average credit rating (computed by calculating the simple average of a bond’s rating published by S&P, Fitch and Moody’s and then rounding down to the nearest rating step) of CCC- from S&P, Fitch and Moody’s; and (iv) have at least $200 million in face value outstanding (existing bonds in the eligible universe require $150 million in face value outstanding to remain eligible).

The eligible universe may include securities issued in accordance with Rule 144A under the Securities Act of 1933, as amended (“Securities Act”).

2024 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 197 constituents.

The Fund will terminate on or about December 15, 2024. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2024), no new constituents are added and the Underlying Index does not rebalance. In the last twelve months of operation, when the 2024 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2024 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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 may 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.

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 RAFI(TM) Strategic Developed ex-US ETF

Invesco RAFI™ Strategic Developed ex-US ETF Summary Information

Investment Objective

The Invesco RAFI^TM Strategic Developed ex-US ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Invesco Strategic Developed ex-US 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 RAFI(TM) Strategic Developed ex-US ETF Invesco RAFI(TM) Strategic Developed ex-US ETF
Management Fees	0.23%
Other Expenses	none	[1]
Total Annual Fund Operating Expenses	0.23%

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	5 Years	10 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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the fiscal period September 10, 2018 (commencement of operations) through August 31, 2019, the Fund’s portfolio turnover rate was 47% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in securities that comprise the Underlying Index and American depositary receipts (“ADRs”) and global depositary receipts (“GDRs”) that are based on securities in 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 measure the performance of equity securities issued by higher quality, large-business-sized companies located in countries designated as developed market countries (excluding the U.S.). 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 Index Provider selects components for inclusion in the Underlying Index from an investment universe of foreign equity securities with at least one year of trading history, issued by companies located in countries designated as developed market countries (excluding the U.S.). Each eligible equity security is assigned a business-size score (“Business-Size Score”) based on the equally-weighted average of the following four factors of company size over the prior five years (or, if shorter, the life of the security): sales, operating cash flow, total return of capital (dividends and share repurchases) and book value. For real estate securities (real estate investment trusts (“REITs”) and common stocks of companies in the real estate sector), operating cash flow is replaced by funds from operations and book value is replaced by total assets.

Each eligible security is then assigned a quality score (“Quality Score”) based on the equally-weighted average of the following two quality factors: efficiency (calculated as the ratio of sales-to-assets in the prior year) and growth (calculated as the percentage change in the ratio of sales-to-assets over the prior five years (or, if shorter, the life of the security)).

Each eligible security is ranked in descending order by its Business-Size Score. Those securities in the top 90% by Business-Size Score are eligible for inclusion in the Underlying Index and, of those, the 80% with the highest Quality Scores are included in the Underlying Index. Securities in the Underlying Index are weighted based on their float-adjusted Business-Size Scores.  

As of August 31, 2019, the following countries were classified as developed markets (excluding the U.S.) by the Index Provider: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, Luxembourg, the Netherlands, New Zealand, Norway, Portugal, Singapore, South Korea, Spain, Sweden, Switzerland, and United Kingdom.

As of August 31, 2019, the Underlying Index was comprised of 795 constituents.

The Fund employs a “full replication” methodology in seeking to track the Underlying Index, meaning that the Fund generally invests in all of the securities comprising the Underlying Index in proportion to their weightings in the Underlying Index.

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.

ADR and GDR Risk. ADRs are certificates that evidence ownership of shares of a foreign issuer and are alternatives to purchasing the underlying foreign securities directly in their national markets and currencies. GDRs are certificates issued by an international bank that generally are traded and denominated in the currencies of countries other than the home country of the issuer of the underlying shares. ADRs and GDRs may be subject to certain of the risks associated with direct investments in the securities of foreign companies, such as currency, political, economic and market risks, because their values depend on the performance of the non-dollar denominated underlying foreign securities. Moreover, ADRs and GDRs may not track the price of the underlying foreign securities on which they are based, and their value may change materially at times when U.S. markets are not open for trading.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar. Generally, an increase in the value of the U.S. dollar against a foreign currency will reduce the value of a security denominated in that foreign currency, thereby decreasing the Fund’s overall NAV. Exchange rates may be volatile and may change quickly and unpredictably in response to both global economic developments and economic conditions, causing an adverse impact on the Fund. As a result, investors have the potential for losses regardless of the length of time they intend to hold Shares.

Equity Risk. Equity risk is the risk that the value of equity securities, including common stocks, may fall due to both changes in general economic conditions that impact the market as a whole, as well as factors that directly relate to a specific company or its industry. Such general economic conditions include changes in interest rates, periods of market turbulence or instability, or general and prolonged periods of economic decline and cyclical change. It is possible that a drop in the stock market may depress the price of most or all of the common stocks that the Fund holds. In addition, equity risk includes the risk that investor sentiment toward one or more industries will become negative, resulting in those investors exiting their investments in those industries, which could cause a reduction in the value of companies in those industries more broadly. The value of a company’s common stock may fall solely because of factors, such as an increase in production costs, that negatively impact other companies in the same region, industry or sector of the market. A company’s common stock also may decline significantly in price over a short period of time due to factors specific to that company, including decisions made by its management or lower demand for the company’s products or services. For example, an adverse event, such as an unfavorable earnings report or the failure to make anticipated dividend payments, may depress the value of common stock.

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. As the Fund will invest in securities denominated in foreign currencies, fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in foreign securities and may negatively impact the Fund’s returns.

Geographic Concentration Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in that specific geographic region and adversely impact the Fund’s investments in the affected region.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

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.

Mid-Capitalization Company Risk. Investing in securities of mid-capitalization companies involves greater risk than is customarily associated with investing in larger, more established companies. These companies’ securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often mid-capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions.

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. 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

REIT Risk. REITs are subject to risks inherent in the direct ownership of real estate. These risks include, but are not limited to, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. REITs may be affected by changes in the values of the underlying properties that they own or operate and could fail to qualify for favorable tax or regulatory treatment. REITs also are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs rely heavily on cash flows and a variety of economic and other factors may adversely affect a lessee’s ability to meet its obligations to a REIT. Should a lessee default on their loan, the REIT may experience delays in enforcing its rights as a lessor and may incur substantial costs associated in protecting its investments.

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 securities and, because foreign exchanges may be open on days when the Fund does not price its Shares, the value of those 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 NAV of such Shares.

Performance

The Fund commenced operations on September 10, 2018 and therefore does not have a full calendar year of performance history. Once the Fund has a full calendar year of performance information, the Fund will present total return information, which is also accessible on the Fund’s website at www.invesco.com/ETFs and provides some indication of the risks of investing in the Fund.

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 measure the performance of equity securities issued by higher quality, small-business-sized companies designated as U.S. companies. 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 Index Provider selects components for inclusion in the Underlying Index from an investment universe of domestic equity securities with at least one year of trading history. Each eligible equity security is assigned a business-size score (“Business-Size Score”) based on the equally-weighted average of the following four factors of company size over the prior five years (or, if shorter, the life of the security): sales, operating cash flow, total return of capital (dividends and share repurchases) and book value. For real estate securities (real estate investment trusts (“REITs”) and common stocks of companies in the real estate sector), operating cash flow is replaced by funds from operations and book value is replaced by total assets.

Each eligible security is ranked in descending order by its Business-Size Score. Those securities ranked below 90% by Business-Size Score are eligible for inclusion in the Underlying Index and, of those, the 80% with the highest Quality Scores are included in the Underlying Index. Securities in the Underlying Index are weighted based on their float-adjusted Business-Size Scores.

As of August 31, 2019, the Underlying Index was comprised of 1,216 constituents.

The Fund employs a “full replication” methodology in seeking to track the Underlying Index, meaning that the Fund generally invests in all of the securities comprising the Underlying Index in proportion to their weightings in the Underlying Index. 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”).

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

Equity Risk. Equity risk is the risk that the value of equity securities, including common stocks, may fall due to both changes in general economic conditions that impact the market as a whole, as well as factors that directly relate to a specific company or its industry. Such general economic conditions include changes in interest rates, periods of market turbulence or instability, or general and prolonged periods of economic decline and cyclical change. It is possible that a drop in the stock market may depress the price of most or all of the common stocks that the Fund holds. In addition, equity risk includes the risk that investor sentiment toward one or more industries will become negative, resulting in those investors exiting their investments in those industries, which could cause a reduction in the value of companies in those industries more broadly. The value of a company’s common stock may fall solely because of factors, such as an increase in production costs, that negatively impact other companies in the same region, industry or sector of the market. A company’s common stock also may decline significantly in price over a short period of time due to factors specific to that company, including decisions made by its management or lower demand for the company’s products or services. For example, an adverse event, such as an unfavorable earnings report or the failure to make anticipated dividend payments, may depress the value of common stock.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares, or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns.

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. 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

REIT Risk. REITs are subject to risks inherent in the direct ownership of real estate. These risks include, but are not limited to, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. REITs may be affected by changes in the values of the underlying properties that they own or operate and could fail to qualify for favorable tax or regulatory treatment. REITs also are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs rely heavily on cash flows and a variety of economic and other factors may adversely affect a lessee’s ability to meet its obligations to a REIT. Should a lessee default on their loan, the REIT may experience delays in enforcing its rights as a lessor and may incur substantial costs associated in protecting its investments.

Small- and Mid-Capitalization Company Risk. Investing in securities of small- and mid-capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies’ securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small- and mid-capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions.

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 14% of the average value of its portfolio.

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated high yield corporate bonds (commonly known as “junk bonds”) with maturities or, in some cases, “effective maturities” in the year 2025 (collectively, “2025 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) have a maximum rating of BB+ from S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or a maximum rating of Ba1 from Moody’s Investors Service, Inc. (“Moody’s”); (iii) have a minimum average credit rating (computed by calculating the simple average of a bond’s rating published by S&P, Fitch and Moody’s and then rounding down to the nearest rating step) of CCC- from S&P, Fitch and Moody’s; and (iv) have at least $200 million in face value outstanding (existing bonds in the eligible universe require $150 million in face value outstanding to remain eligible).

The eligible universe may include securities issued in accordance with Rule 144A under the Securities Act of 1933, as amended (“Securities Act”).

2025 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 249 constituents.

The Fund will terminate on or about December 15, 2025. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2025), no new constituents are added and the Underlying Index does not rebalance. In the last twelve months of operation, when the 2025 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2025 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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 may 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.

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.

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.

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated high yield corporate bonds (commonly known as “junk bonds”) with maturities or, in some cases, “effective maturities” in the year 2026 (collectively, “2026 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date. In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) have a maximum rating of BB+ from S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or a maximum rating of Ba1 from Moody’s Investors Service, Inc. (“Moody’s”); (iii) have a minimum average credit rating (computed by calculating the simple average of a bond’s rating published by S&P, Fitch and Moody’s and then rounding down to the nearest rating step) of CCC- from S&P, Fitch and Moody’s; and (iv) have at least $200 million in face value outstanding (existing bonds in the eligible universe require $150 million in face value outstanding to remain eligible). The eligible universe may include securities issued in accordance with Rule 144A under the Securities Act of 1933, as amended (“Securities Act”). 2026 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index. As of August 31, 2019, the Underlying Index was comprised of 154 constituents. The Fund will terminate on or about December 15, 2026. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2026), no new constituents are added and the Underlying Index does not rebalance. In the last twelve months of operation, when the 2026 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2026 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time. 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. 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 exercises 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 changes to 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. Declining Yield Risk. During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market. 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. Fluctuation of Yield and Liquidation Amount Risk. The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes. Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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. 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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. Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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 may 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. 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 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 (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses	Invesco Investment Grade Defensive ETF Invesco Investment Grade Defensive ETF
Management Fees	0.13%
Other Expenses	none	[1]
Total Annual Fund Operating Expenses	0.13%

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	5 Years	10 Years
Invesco Investment Grade Defensive ETF | Invesco Investment Grade Defensive ETF | USD ($)	13	42	73	166

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. During the most recent fiscal year, the portfolio turnover rate of the Fund was 71% of the average value of its portfolio.

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) have an average credit rating that is 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 in face value 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 new eligible security with a Quality Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index constituents with a Quality Score in the top 50% of eligible securities remain in the Underlying Index provided that they satisfy all other eligibility criteria. Underlying Index constituents are equally weighted.

As of August 31, 2019, the Underlying Index was comprised of 113 constituents.

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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates its investments, 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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.

Performance

The Fund commenced operations on July 23, 2018 and therefore does not yet have a full calendar year of performance history. Once the Fund has a full calendar year of performance information, the Fund will present total return information which is also accessible on the Fund’s website at www.invesco.com/ETFs and provides some indication of the risks of investing in the Fund.

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

Annual Fund Operating Expenses	Invesco Emerging Markets Debt Value ETF Invesco Emerging Markets Debt Value 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	5 Years	10 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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 96% of the average value of its portfolio.

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 August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, 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) have an average credit rating that is 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 in face value 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 bond type 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 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 new eligible security with a QAV Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index constituents with a QAV Score in the top 60% of eligible securities remain in the Underlying Index provided that they satisfy all other eligibility criteria. Underlying Index constituents are modified market-value weighted.  

As of August 31, 2019, the Underlying Index was comprised of 160 constituents.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Privately-Issued Securities Risk. The Fund may invest in privately-issued securities, including those that are normally purchased or resold pursuant to 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. As such Rule 144A and Regulation S securities may be subject to legal restrictions on resale. Privately-issued securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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

The Fund commenced operations on July 23, 2018 and therefore does not yet have a full calendar year of performance history. Once the Fund has a full calendar year of performance information, the Fund will present total return information which is also accessible on the Fund’s website at www.invesco.com/ETFs and provides some indication of the risks of investing in the Fund.

Invesco BulletShares 2023 USD Emerging Markets Debt ETF

Invesco BulletShares 2023 USD Emerging Markets Debt ETF Summary Information

Investment Objective

The Invesco BulletShares 2023 USD Emerging Markets Debt ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Nasdaq BulletShares^® USD Emerging Markets Debt 2023 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 BulletShares 2023 USD Emerging Markets Debt ETF Invesco BulletShares 2023 USD Emerging Markets Debt 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	5 Years	10 Years
Invesco BulletShares 2023 USD Emerging Markets Debt ETF | Invesco BulletShares 2023 USD Emerging Markets Debt ETF | USD ($)	30	93	163	368

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the fiscal period October 2, 2018 (commencement of operations) through August 31, 2019, the portfolio turnover rate of the Fund was 16% of the average value of its portfolio.

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. 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 designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated emerging markets bonds with maturities or, in some cases, “effective maturities” in the year 2023 (collectively, “2023 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond, then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price, then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of investment grade and below investment grade U.S. dollar-denominated bonds issued by governments of countries that the Index Provider considers to be “emerging markets countries,” or by companies, sovereign entities or government-related agencies domiciled in such countries (as of August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, 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) have a credit rating of at least C by S&P Global Ratings, a division of S&P Global Inc. (“S&P”) or Fitch Ratings Inc. (“Fitch”), or at least a credit rating of Ca by Moody’s Investors Service, Inc. (“Moody’s”); and (ii) have an outstanding face value of at least $300 million for corporate bonds and $500 million for other bonds (existing bonds in the eligible universe require 80% of the initial minimum face value outstanding qualification, depending on type of bond, to remain eligible). Bonds rated below BBB- by S&P or Fitch, or below Baa3 by Moody’s are considered below investment grade (commonly known as “junk bonds”) and are considered speculative.

The eligible universe may include: fixed- and step up-coupon bonds; puttable and callable bonds; event-driven, rating-driven, and registration-driven bonds; amortizing bonds; sinking funds with fixed sinking schedules; and securities issued in accordance with Regulation S or Rule 144A under the Securities Act of 1933 (“Securities Act”) that are exempt from registration with the Securities and Exchange Commission (“SEC”). Additionally, bond types specifically excluded from the eligible universe include: private placements, except for Regulation S and Rule 144A bonds; pay-in-kind bonds; floating rate notes; zero coupon bonds, including zero coupon step-ups; convertible bonds; bonds cum or ex-warrant; bonds with one cash flow only; new bonds that have already been called; inflation or other index-linked bonds; bonds whose price, including interest that has accrued since the issue of the most recent coupon payment, is below $80; perpetual securities (including trust preferred); and preferred shares.

2023 Bonds (as established semi-annually, as further described below) in the eligible universe are selected for inclusion in the Underlying Index and market value weighted, with a 5% limit on individual issuers and a 10% limit on countries applied at each monthly rebalance. Prior to the final year of maturity (i.e., 2023), the Underlying Index is rebalanced monthly, at which time: (i) new bonds that meet the eligibility and maturity (or effective maturity) criteria above are added to the Underlying Index; (ii) existing 2023 Bonds that no longer meet the eligibility requirements are removed; and (iii) weights of Underlying Index components are reset to reflect current market value. The Index Provider only reevaluates the effective maturity date of bonds in the investment universe semi-annually, as part of the June and December rebalances, at which time in addition to bonds being added or removed from the Underlying Index pursuant to the eligibility screening described in the previous sentence, bonds also may be added or removed from the Underlying Index due to any changes in actual or effective maturity (i.e., they no longer meet the definition of 2023 Bond). If a bond is removed from the Underlying Index during any rebalance due to changes in face value or credit rating, such bond will be excluded for the next three monthly rebalances (including the current rebalance) regardless of any further changes in face value or credit rating. During the final year of maturity (i.e., 2023), the Underlying Index does not rebalance.

The Fund primarily invests in 2023 Bonds and the Fund will terminate on or about December 31, 2023. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. Bonds held by the Fund will be held until they mature, are called, or are removed from the Underlying Index due to no longer meeting the eligibility requirements. Ineligible bonds are not removed from an Underlying Index until its next rebalance. Therefore, to the extent a bond held by the Fund is no longer eligible for inclusion in an Underlying Index, the Fund will continue to hold such bond until it is removed from the respective Underlying Index at its next rebalance. In the last year of operation, when the 2023 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2023 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

As of August 31, 2019, the Underlying Index was comprised of 249 constituents.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

Emerging Markets Investment Risk. Investments in the securities of issuers in emerging market countries involve risks often not associated with investments in the securities of issuers in developed countries. Securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets. Fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in emerging market securities, and emerging market securities may have relatively low market liquidity, decreased publicly available 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. Emerging market securities also are subject to the risks of expropriation, nationalization or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in emerging market securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions. Emerging markets usually are subject to greater market volatility, lower trading volume, political and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Securities law in many emerging market countries is relatively new and unsettled. Therefore, laws regarding foreign investment in emerging market securities, securities regulation, title to securities, and shareholder rights may change quickly and unpredictably. In addition, the enforcement of systems of taxation at federal, regional and local levels in emerging market countries may be inconsistent and subject to sudden change.

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns.

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 and unrated securities of comparable credit quality are considered speculative and 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

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 may result in its holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development with respect to an issuer of securities held by the Fund 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

The Fund commenced operations on October 2, 2018 and therefore does not yet have a full calendar year of performance history. Once the Fund has a full calendar year of performance information, the Fund will present total return information, which is also accessible on the Fund’s website at www.invesco.com/ETFs and provides some indication of the risks of investing in the Fund.

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	5 Years	10 Years
Invesco Emerging Markets Debt Defensive ETF | Invesco Emerging Markets Debt Defensive ETF | USD ($)	30	93	163	368

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 110% of the average value of its portfolio.

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 August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, 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) have an average credit rating that is 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 in face value 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 new eligible security with a Quality Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index constituents with a Quality Score in the top 60% of eligible securities remain in the Underlying Index provided that they satisfy all other eligibility criteria. Underlying Index constituents are modified market-value weighted.  

As of August 31, 2019, the Underlying Index was comprised of 103 constituents.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Portfolio Turnover Risk. The Fund may engage in frequent trading of its portfolio securities in connection with the rebalancing or adjustment of the Underlying Index. A portfolio turnover rate of 200%, for example, is equivalent to the Fund buying and selling all of its securities two times during the course of a year. A high portfolio turnover rate (such as 100% or more) could result in high brokerage costs for the Fund.

Privately-Issued Securities Risk. The Fund may invest in privately-issued securities, including those that are normally purchased or resold pursuant to 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. As such Rule 144A and Regulation S securities may be subject to legal restrictions on resale. Privately-issued securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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

The Fund commenced operations on July 23, 2018 and therefore does not yet have a full calendar year of performance history. Once the Fund has a full calendar year of performance information, the Fund will present total return information which is also accessible on the Fund’s website at www.invesco.com/ETFs and provides some indication of the risks of investing in the Fund.

Invesco BulletShares 2024 USD Emerging Markets Debt ETF

Invesco BulletShares 2024 USD Emerging Markets Debt ETF Summary Information

Investment Objective

The Invesco BulletShares 2024 USD Emerging Markets Debt ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Nasdaq BulletShares^® USD Emerging Markets Debt 2024 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 BulletShares 2024 USD Emerging Markets Debt ETF Invesco BulletShares 2024 USD Emerging Markets Debt 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:

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the fiscal period October 2, 2018 (commencement of operations) through August 31, 2019, the portfolio turnover rate of the Fund was 10% of the average value of its portfolio.

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. 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 designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated emerging markets bonds with maturities or, in some cases, “effective maturities” in the year 2024 (collectively, “2024 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond, then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price, then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of investment grade and below investment grade U.S. dollar-denominated bonds issued by governments of countries that the Index Provider considers to be “emerging markets countries,” or by companies, sovereign entities or government-related agencies domiciled in such countries (as of August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, 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) have a credit rating of at least C by S&P Global Ratings, a division of S&P Global Inc. (“S&P”) or Fitch Ratings Inc. (“Fitch”), or at least a credit rating of Ca by Moody’s Investors Service, Inc. (“Moody’s”); and (ii) have an outstanding face value of at least $300 million for corporate bonds and $500 million for other bonds (existing bonds in the eligible universe require 80% of the initial minimum face value outstanding qualification, depending on type of bond, to remain eligible). Bonds rated below BBB- by S&P or Fitch, or below Baa3 by Moody’s are considered below investment grade (commonly known as “junk bonds”) and are considered speculative.

The eligible universe may include: fixed- and step up-coupon bonds; puttable and callable bonds; event-driven, rating-driven, and registration-driven bonds; amortizing bonds; sinking funds with fixed sinking schedules; and securities issued in accordance with Regulation S or Rule 144A under the Securities Act of 1933 (“Securities Act”) that are exempt from registration with the Securities and Exchange Commission (“SEC”). Additionally, bond types specifically excluded from the eligible universe include: private placements, except for Regulation S and Rule 144A bonds; pay-in-kind bonds; floating rate notes; zero coupon bonds, including zero coupon step-ups; convertible bonds; bonds cum or ex-warrant; bonds with one cash flow only; new bonds that have already been called; inflation or other index-linked bonds; bonds whose price, including interest that has accrued since the issue of the most recent coupon payment, is below $80; perpetual securities (including trust preferred); and preferred shares.

2024 Bonds (as established semi-annually, as further described below) in the eligible universe are selected for inclusion in the Underlying Index and market value weighted, with a 5% limit on individual issuers and a 10% limit on countries applied at each monthly rebalance. Prior to the final year of maturity (i.e., 2024), the Underlying Index is rebalanced monthly, at which time: (i) new bonds that meet the eligibility and maturity (or effective maturity) criteria above are added to the Underlying Index; (ii) existing 2024 Bonds that no longer meet the eligibility requirements are removed; and (iii) weights of Underlying Index components are reset to reflect current market value. The Index Provider only reevaluates the effective maturity date of bonds in the investment universe semi-annually, as part of the June and December rebalances, at which time in addition to bonds being added or removed from the Underlying Index pursuant to the eligibility screening described in the previous sentence, bonds also may be added or removed from the Underlying Index due to any changes in actual or effective maturity (i.e., they no longer meet the definition of 2024 Bond). If a bond is removed from the Underlying Index during any rebalance due to changes in face value or credit rating, such bond will be excluded for the next three monthly rebalances (including the current rebalance) regardless of any further changes in face value or credit rating. During the final year of maturity (i.e., 2024), the Underlying Index does not rebalance.

The Fund primarily invests in 2024 Bonds and the Fund will terminate on or about December 31, 2024. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. Bonds held by the Fund will be held until they mature, are called, or are removed from the Underlying Index due to no longer meeting the eligibility requirements. Ineligible bonds are not removed from an Underlying Index until its next rebalance. Therefore, to the extent a bond held by the Fund is no longer eligible for inclusion in an Underlying Index, the Fund will continue to hold such bond until it is removed from the respective Underlying Index at its next rebalance. In the last year of operation, when the 2024 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2024 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

As of August 31, 2019, the Underlying Index was comprised of 216 constituents.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

Emerging Markets Investment Risk. Investments in the securities of issuers in emerging market countries involve risks often not associated with investments in the securities of issuers in developed countries. Securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets. Fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in emerging market securities, and emerging market securities may have relatively low market liquidity, decreased publicly available 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. Emerging market securities also are subject to the risks of expropriation, nationalization or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in emerging market securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions. Emerging markets usually are subject to greater market volatility, lower trading volume, political and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Securities law in many emerging market countries is relatively new and unsettled. Therefore, laws regarding foreign investment in emerging market securities, securities regulation, title to securities, and shareholder rights may change quickly and unpredictably. In addition, the enforcement of systems of taxation at federal, regional and local levels in emerging market countries may be inconsistent and subject to sudden change.

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns.

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 and unrated securities of comparable credit quality are considered speculative and 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

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 may result in its holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development with respect to an issuer of securities held by the Fund 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

The Fund commenced operations on October 2, 2018 and therefore does not yet have a full calendar year of performance history. Once the Fund has a full calendar year of performance information, the Fund will present total return information, which is also accessible on the Fund’s website at www.invesco.com/ETFs and provides some indication of the risks of investing in the 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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 114% of the average value of its portfolio.

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”) and bonds with the lowest credit rating considered investment grade. 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. 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) have an average credit rating that is higher than B- and lower than or equal to 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 in face value 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 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 new eligible security with a QAV Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index constituents with a QAV Score in the top 50% of eligible securities remain in the Underlying Index provided that they satisfy all other eligibility criteria. Underlying Index constituents are equally weighted.  

As of August 31, 2019, the Underlying Index was comprised of 197 constituents.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Portfolio Turnover Risk. The Fund may engage in frequent trading of its portfolio securities in connection with the rebalancing or adjustment of the Underlying Index. A portfolio turnover rate of 200%, for example, is equivalent to the Fund buying and selling all of its securities two times during the course of a year. A high portfolio turnover rate (such as 100% or more) could result in high brokerage costs for the Fund.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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.

Performance

The Fund commenced operations on July 23, 2018 and therefore does not yet have a full calendar year of performance history. Once the Fund has a full calendar year of performance information, the Fund will present total return information which is also accessible on the Fund’s website at www.invesco.com/ETFs and provides some indication of the risks of investing in the Fund.

Invesco BulletShares 2020 Corporate Bond ETF

Invesco BulletShares 2020 Corporate Bond ETF Summary Information

Investment Objective

The Invesco BulletShares 2020 Corporate Bond ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Nasdaq BulletShares^® USD Corporate Bond 2020 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 BulletShares 2020 Corporate Bond ETF Invesco BulletShares 2020 Corporate Bond ETF
Management Fees	0.10%
Other Expenses	none
Total Annual Fund Operating Expenses	0.10%

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	5 Years	10 Years
Invesco BulletShares 2020 Corporate Bond ETF | Invesco BulletShares 2020 Corporate Bond ETF | USD ($)	10	32	57	128

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 9% of the average value of its portfolio.

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.

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 seeks to measure the performance of a portfolio of U.S. dollar-denominated investment grade corporate bonds with maturities or, in some cases, “effective maturities” in the year 2020 (collectively, “2020 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) be rated at least BBB- by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or at least Baa3 by Moody’s Investors Service, Inc. (“Moody’s”); and (iii) have at least $500 million in face value outstanding (existing bonds in the eligible universe require $400 million in face value outstanding to remain eligible).

2020 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 373 constituents.

The Fund will terminate on or about December 15, 2020. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2020), no new constituents are added and the Underlying Index rebalances only through June. In the last six months of operation, when the 2020 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2020 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates, 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Sampling Risk. The Fund’s use of a representative sampling approach may 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.

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

The bar chart below shows how the Fund has performed. The table below the bar chart shows the Fund’s average annual total returns (before and after taxes). The bar chart and table provide an indication of the risks of investing in the Fund by showing how the Fund’s total returns have varied from year to year and by showing how the Fund’s average annual total returns compared with a broad measure of market performance and an additional index with characteristics relevant to the Fund. Although the information shown in the bar chart and the table gives you some idea of the risks involved in investing in the Fund, the Fund’s past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future.

The Fund is the successor to the investment performance of the Guggenheim BulletShares 2020 Corporate Bond ETF (the “Predecessor Fund”) as a result of the reorganization of the Predecessor Fund into the Fund, which was consummated after the close of business on April 6, 2018. Accordingly, the performance information shown below for periods ending on or prior to April 6, 2018 is that of the Predecessor Fund. Updated performance information is available online at www.invesco.com/ETFs.

Invesco Corporate Income Defensive ETF

Invesco Corporate Income Defensive ETF Summary Information

Investment Objective

The Invesco Corporate Income Defensive ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Invesco High Yield 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)

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 78% of the average value of its portfolio.

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. corporate bonds having the highest “quality scores” within an eligible universe of U.S. high yield bonds (commonly known as “junk bonds”) and bonds with the lowest credit rating considered investment grade, all 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) have an average credit rating that is higher than B- and lower than or equal to 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 in face value 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 new eligible security with a Quality Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index constituents with a Quality Score in the top 50% of eligible securities remain in the Underlying Index provided that they satisfy all other eligibility criteria. Underlying Index constituents are equally weighted.  

As of August 31, 2019, the Underlying Index was comprised of 159 constituents.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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.

Performance

The Fund commenced operations on July 23, 2018 and therefore does not yet have a full calendar year of performance history. Once the Fund has a full calendar year of performance information, the Fund will present total return information which is also accessible on the Fund’s website at www.invesco.com/ETFs and provides some indication of the risks of investing in the Fund.

[1] Other Expenses do not reflect any extraordinary expenses incurred during the most recent fiscal period, such as the costs associated with a proxy statement of the Fund. Had these expenses been included, Other Expenses would have been 0.02%.

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. 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 designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated emerging markets bonds with maturities or, in some cases, “effective maturities” in the year 2021 (collectively, “2021 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond, then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price, then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date. In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of investment grade and below investment grade U.S. dollar-denominated bonds issued by governments of countries that the Index Provider considers to be “emerging markets countries,” or by companies, sovereign entities or government-related agencies domiciled in such countries (as of August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, 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) have a credit rating of at least C by S&P Global Ratings, a division of S&P Global Inc. (“S&P”) or Fitch Ratings Inc. (“Fitch”), or at least a credit rating of Ca by Moody’s Investors Service, Inc. (“Moody’s”); and (ii) have an outstanding face value of at least $300 million for corporate bonds and $500 million for other bonds (existing bonds in the eligible universe require 80% of the initial minimum face value outstanding qualification, depending on type of bond, to remain eligible). Bonds rated below BBB- by S&P or Fitch, or below Baa3 by Moody’s are considered below investment grade (commonly known as “junk bonds”) and are considered speculative. The eligible universe may include: fixed- and step up-coupon bonds; puttable and callable bonds; event-driven, rating-driven, and registration-driven bonds; amortizing bonds; sinking funds with fixed sinking schedules; and securities issued in accordance with Regulation S or Rule 144A under the Securities Act of 1933 (“Securities Act”) that are exempt from registration with the Securities and Exchange Commission (“SEC”). Additionally, bond types specifically excluded from the eligible universe include: private placements, except for Regulation S and Rule 144A bonds; pay-in-kind bonds; floating rate notes; zero coupon bonds, including zero coupon step-ups; convertible bonds; bonds cum or ex-warrant; bonds with one cash flow only; new bonds that have already been called; inflation or other index-linked bonds; bonds whose price, including interest that has accrued since the issue of the most recent coupon payment, is below $80; perpetual securities (including trust preferred); and preferred shares. 2021 Bonds (as established semi-annually, as further described below) in the eligible universe are selected for inclusion in the Underlying Index and market value weighted, with a 5% limit on individual issuers and a 10% limit on countries applied at each monthly rebalance. Prior to the final year of maturity (i.e., 2021), the Underlying Index is rebalanced monthly, at which time: (i) new bonds that meet the eligibility and maturity (or effective maturity) criteria above are added to the Underlying Index; (ii) existing 2021 Bonds that no longer meet the eligibility requirements are removed; and (iii) weights of Underlying Index components are reset to reflect current market value. The Index Provider only reevaluates the effective maturity date of bonds in the investment universe semi-annually, as part of the June and December rebalances, at which time in addition to bonds being added or removed from the Underlying Index pursuant to the eligibility screening described in the previous sentence, bonds also may be added or removed from the Underlying Index due to any changes in actual or effective maturity (i.e., they no longer meet the definition of 2021 Bond). If a bond is removed from the Underlying Index during any rebalance due to changes in face value or credit rating, such bond will be excluded for the next three monthly rebalances (including the current rebalance) regardless of any further changes in face value or credit rating. During the final year of maturity (i.e., 2021), the Underlying Index does not rebalance. The Fund primarily invests in 2021 Bonds and the Fund will terminate on or about December 31, 2021. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. Bonds held by the Fund will be held until they mature, are called, or are removed from the Underlying Index due to no longer meeting the eligibility requirements. Ineligible bonds are not removed from an Underlying Index until its next rebalance. Therefore, to the extent a bond held by the Fund is no longer eligible for inclusion in an Underlying Index, the Fund will continue to hold such bond until it is removed from the respective Underlying Index at its next rebalance. In the last year of operation, when the 2021 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2021 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time. As of August 31, 2019, the Underlying Index was comprised of 261 constituents. 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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates, are likely to change over time.

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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. 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 exercises 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 changes to 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. Declining Yield Risk. During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market. Emerging Markets Investment Risk. Investments in the securities of issuers in emerging market countries involve risks often not associated with investments in the securities of issuers in developed countries. Securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets. Fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in emerging market securities, and emerging market securities may have relatively low market liquidity, decreased publicly available 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. Emerging market securities also are subject to the risks of expropriation, nationalization or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in emerging market securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions. Emerging markets usually are subject to greater market volatility, lower trading volume, political and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Securities law in many emerging market countries is relatively new and unsettled. Therefore, laws regarding foreign investment in emerging market securities, securities regulation, title to securities, and shareholder rights may change quickly and unpredictably. In addition, the enforcement of systems of taxation at federal, regional and local levels in emerging market countries may be inconsistent and subject to sudden change. 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. Fluctuation of Yield and Liquidation Amount Risk. The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes. Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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. 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole. Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies. 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. Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. 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 and unrated securities of comparable credit quality are considered speculative and 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. 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 may result in its holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development with respect to an issuer of securities held by the Fund 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. 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.

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) have an average credit rating that is 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 in face value 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 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 new eligible security with a QAV Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index constituents with a QAV Score in the top 50% of eligible securities remain in the Underlying Index provided that they satisfy all other eligibility criteria. Underlying Index constituents are equally weighted.   As of August 31, 2019, the Underlying Index was comprised of 131 constituents. 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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates its investments, 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. 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 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole. Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies. 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. Portfolio Turnover Risk. The Fund may engage in frequent trading of its portfolio securities in connection with the rebalancing or adjustment of the Underlying Index. A portfolio turnover rate of 200%, for example, is equivalent to the Fund buying and selling all of its securities two times during the course of a year. A high portfolio turnover rate (such as 100% or more) could result in high brokerage costs for the Fund. Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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. 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 designed to represent the performance of a held-to-maturity portfolio of U.S. dollar-denominated emerging markets bonds with maturities or, in some cases, “effective maturities” in the year 2022 (collectively, “2022 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond, then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price, then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date. In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of investment grade and below investment grade U.S. dollar-denominated bonds issued by governments of countries that the Index Provider considers to be “emerging markets countries,” or by companies, sovereign entities or government-related agencies domiciled in such countries (as of August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, 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) have a credit rating of at least C by S&P Global Ratings, a division of S&P Global Inc. (“S&P”) or Fitch Ratings Inc. (“Fitch”), or at least a credit rating of Ca by Moody’s Investors Service, Inc. (“Moody’s”); and (ii) have an outstanding face value of at least $300 million for corporate bonds and $500 million for other bonds (existing bonds in the eligible universe require 80% of the initial minimum face value outstanding qualification, depending on type of bond, to remain eligible). Bonds rated below BBB- by S&P or Fitch, or below Baa3 by Moody’s are considered below investment grade (commonly known as “junk bonds”) and are considered speculative. The eligible universe may include: fixed- and step up-coupon bonds; puttable and callable bonds; event-driven, rating-driven, and registration-driven bonds; amortizing bonds; sinking funds with fixed sinking schedules; and securities issued in accordance with Regulation S or Rule 144A under the Securities Act of 1933 (“Securities Act”) that are exempt from registration with the Securities and Exchange Commission (“SEC”). Additionally, bond types specifically excluded from the eligible universe include: private placements, except for Regulation S and Rule 144A bonds; pay-in-kind bonds; floating rate notes; zero coupon bonds, including zero coupon step-ups; convertible bonds; bonds cum or ex-warrant; bonds with one cash flow only; new bonds that have already been called; inflation or other index-linked bonds; bonds whose price, including interest that has accrued since the issue of the most recent coupon payment, is below $80; perpetual securities (including trust preferred); and preferred shares. 2022 Bonds (as established semi-annually, as further described below) in the eligible universe are selected for inclusion in the Underlying Index and market value weighted, with a 5% limit on individual issuers and a 10% limit on countries applied at each monthly rebalance. Prior to the final year of maturity (i.e., 2022), the Underlying Index is rebalanced monthly, at which time: (i) new bonds that meet the eligibility and maturity (or effective maturity) criteria above are added to the Underlying Index; (ii) existing 2022 Bonds that no longer meet the eligibility requirements are removed; and (iii) weights of Underlying Index components are reset to reflect current market value. The Index Provider only reevaluates the effective maturity date of bonds in the investment universe semi-annually, as part of the June and December rebalances, at which time in addition to bonds being added or removed from the Underlying Index pursuant to the eligibility screening described in the previous sentence, bonds also may be added or removed from the Underlying Index due to any changes in actual or effective maturity (i.e., they no longer meet the definition of 2022 Bond). If a bond is removed from the Underlying Index during any rebalance due to changes in face value or credit rating, such bond will be excluded for the next three monthly rebalances (including the current rebalance) regardless of any further changes in face value or credit rating. During the final year of maturity (i.e., 2022), the Underlying Index does not rebalance. The Fund primarily invests in 2022 Bonds and the Fund will terminate on or about December 31, 2022. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. Bonds held by the Fund will be held until they mature, are called, or are removed from the Underlying Index due to no longer meeting the eligibility requirements. Ineligible bonds are not removed from an Underlying Index until its next rebalance. Therefore, to the extent a bond held by the Fund is no longer eligible for inclusion in an Underlying Index, the Fund will continue to hold such bond until it is removed from the respective Underlying Index at its next rebalance. In the last year of operation, when the 2022 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 31, 2022 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders. The Board may change the termination date to an earlier or later date without shareholder approval. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time. As of August 31, 2019, the Underlying Index was comprised of 310 constituents. 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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates, 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. 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 exercises 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 changes to 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. Declining Yield Risk. During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market. Emerging Markets Investment Risk. Investments in the securities of issuers in emerging market countries involve risks often not associated with investments in the securities of issuers in developed countries. Securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets. Fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in emerging market securities, and emerging market securities may have relatively low market liquidity, decreased publicly available 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. Emerging market securities also are subject to the risks of expropriation, nationalization or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in emerging market securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions. Emerging markets usually are subject to greater market volatility, lower trading volume, political and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Securities law in many emerging market countries is relatively new and unsettled. Therefore, laws regarding foreign investment in emerging market securities, securities regulation, title to securities, and shareholder rights may change quickly and unpredictably. In addition, the enforcement of systems of taxation at federal, regional and local levels in emerging market countries may be inconsistent and subject to sudden change. 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. Fluctuation of Yield and Liquidation Amount Risk. The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes. Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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. 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole. Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies. 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. Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. 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 and unrated securities of comparable credit quality are considered speculative and 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. 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 may result in its holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development with respect to an issuer of securities held by the Fund 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. 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.

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 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 such indexes (each, a “Sub-Index”). The Underlying Index weights the components of the following Sub-Indexes according to the following corresponding fixed, target weightings: (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). As of August 31, 2019, the Underlying Index was comprised of 414 constituents. 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 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 includes 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. Transactions in U.S. government agency mortgage-backed securities may occur through standardized agreements for forward or future delivery in which the actual mortgage pools to be delivered are not specified until shortly prior to settlement (to be announced (“TBA”) transactions). The Fund may engage in such TBA transactions. 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) have an average credit rating that is 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 in face value 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 new eligible security with a Quality Score in the top 30% of eligible securities is added to the IG Defensive Index, and current constituents with a Quality Score in the top 50% of eligible securities remain in the IG Defensive Index provided that they satisfy all other eligibility criteria. IG Defensive Index constituents 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 Treasury 1-3 Years Index constituents 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 Treasury 10-30 Years Index constituents 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 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 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) have an average credit rating that is higher than BBB- (or equivalent) by S&P, Fitch, or Moody’s credit rating agencies; (ii) have at least $600 million in face value 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 quality adjusted value (“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 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 the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores 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 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 new eligible security with a QAV Score in the top 30% of eligible securities is added to the IG Value Index, and current constituents with a QAV Score in the top 50% of eligible securities remain in the IG Value Index provided that they satisfy all other eligibility criteria. IG Value Index constituents 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. 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 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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. Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. 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. In addition, TBA transactions involve the risk that the securities received may be less favorable than what was anticipated by the Fund when entering into the TBA transaction and counterparty risk. Default or bankruptcy of a counterparty to a TBA transaction would expose the Fund to potential loss and could affect the Fund’s returns. 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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.

Management Fees	0.19%
Other Expenses	none	[1]
Total Annual Fund Operating Expenses	0.19%

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	5 Years	10 Years
Invesco RAFI(TM) Strategic US ETF | Invesco RAFI(TM) Strategic US ETF | USD ($)	19	61	107	243

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the fiscal period September 10, 2018 (commencement of operations) through August 31, 2019, the Fund’s portfolio turnover rate was 8% of the average value of its portfolio.

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 measure the performance of equity securities issued by higher quality, large-business-sized companies designated as U.S. companies. 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 Index Provider selects components for inclusion in the Underlying Index from an investment universe of domestic equity securities with at least one year of trading history. Each eligible equity security is assigned a business-size score (“Business-Size Score”) based on the equally-weighted average of the following four factors of company size over the prior five years (or, if shorter, the life of the security): sales, operating cash flow, total return of capital (dividends and share repurchases) and book value. For real estate securities (real estate investment trusts (“REITs”) and common stocks of companies in the real estate sector), operating cash flow is replaced by funds from operations and book value is replaced by total assets.

Each eligible security is then assigned a quality score (“Quality Score”) based on the equally-weighted average of the following two quality factors of its company’s business: efficiency (calculated as the ratio of sales-to-assets in the prior year) and growth (calculated as the percentage change in the ratio of sales-to-assets over the prior five years (or, if shorter, the life of the security)).

Each eligible security is ranked in descending order by its Business-Size Score. Those securities in the top 90% by Business-Size Score are eligible for inclusion in the Underlying Index and, of those, the 80% with the highest Quality Scores are included in the Underlying Index. Securities in the Underlying Index are weighted based on their float-adjusted Business-Size Scores.

As of August 31, 2019, the Underlying Index was comprised of 545 constituents.

The Fund employs a “full replication” methodology in seeking to track the Underlying Index, meaning that the Fund generally invests in all of the securities comprising the Underlying Index in proportion to their weightings in the Underlying Index. 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

Equity Risk. Equity risk is the risk that the value of equity securities, including common stocks, may fall due to both changes in general economic conditions that impact the market as a whole, as well as factors that directly relate to a specific company or its industry. Such general economic conditions include changes in interest rates, periods of market turbulence or instability, or general and prolonged periods of economic decline and cyclical change. It is possible that a drop in the stock market may depress the price of most or all of the common stocks that the Fund holds. In addition, equity risk includes the risk that investor sentiment toward one or more industries will become negative, resulting in those investors exiting their investments in those industries, which could cause a reduction in the value of companies in those industries more broadly. The value of a company’s common stock may fall solely because of factors, such as an increase in production costs, that negatively impact other companies in the same region, industry or sector of the market. A company’s common stock also may decline significantly in price over a short period of time due to factors specific to that company, including decisions made by its management or lower demand for the company’s products or services. For example, an adverse event, such as an unfavorable earnings report or the failure to make anticipated dividend payments, may depress the value of common stock.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

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. 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

REIT Risk. REITs are subject to risks inherent in the direct ownership of real estate. These risks include, but are not limited to, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. REITs may be affected by changes in the values of the underlying properties that they own or operate and could fail to qualify for favorable tax or regulatory treatment. REITs also are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs rely heavily on cash flows and a variety of economic and other factors may adversely affect a lessee’s ability to meet its obligations to a REIT. Should a lessee default on their loan, the REIT may experience delays in enforcing its rights as a lessor and may incur substantial costs associated in protecting its investments.

Performance

The Fund commenced operations on September 10, 2018 and therefore does not have a full calendar year of performance history. Once the Fund has a full calendar year of performance information, the Fund will present total return information, which is also accessible on the Fund’s website at www.invesco.com/ETFs and provides some indication of the risks of investing in the Fund.

[1] Other Expenses do not reflect any extraordinary expenses during the most recent fiscal period, such as the costs associated with a proxy statement of the Fund. Had these expenses been included, Other Expenses would have been 0.02%.

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. During the fiscal period December 4, 2018 (commencement of operations) through August 31, 2019, the portfolio turnover rate of the Fund was 64% of the average value of its portfolio.

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 other indexes and is comprised of component securities of such indexes (each, a “Sub-Index”). The Underlying Index weights the components of the following Sub-Indexes according to the following corresponding fixed, target weightings: (i) Invesco U.S. Fixed Rate 30-Year MBS Index (25% weight); (ii) Invesco Emerging Markets Debt Value Index (15% weight); (iii) Invesco High Yield Defensive Index (15% weight); (iv) Invesco Investment Grade Value Index (15% weight); (v) Invesco Emerging Markets Debt Defensive Index (10% weight); (vi) Invesco High Yield Value Index (10% weight); and (vii) Invesco Investment Grade Defensive Index (10% weight). The Underlying Index will typically include between 500-1,000 securities. The securities in the Underlying Index are weighted pursuant to the Sub-Index allocations set forth above, and such securities are weighted in accordance with the methodology of each Sub-Index. Additional information about each Sub-Index is set forth in “Additional Information About the Funds’ Strategies and Risks”. The Underlying Index is rebalanced monthly, and the Fund will generally rebalance in accordance with the Underlying Index.

In seeking its investment objective, the Fund will generally invest in fixed income securities included in each Sub-Index, which include: (i) mortgage-backed securities based on pools of 30-year mortgages issued by the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”); (ii) U.S. dollar-denominated bonds that are issued by U.S. companies and are considered investment grade (defined by the Index Provider as those with an average credit rating that is 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); (iii) U.S. dollar-denominated high yield bonds (commonly known as “junk bonds”) and bonds with the lowest credit rating considered investment grade, defined by the Index Provider as those that have an average credit rating that is higher than B- and lower than or equal to BBB- (or equivalent) by S&P, Fitch or Moody’s; and (iv) U.S. dollar-denominated bonds have an average credit rating that is higher than B- (or equivalent) by S&P, Fitch or Moody’s issued by sovereign governments, and agencies thereof, of countries that the Index Provider considers to be “emerging market countries” (as of August 31, 2019, the following countries were classified as emerging markets by the Index Provider: Brazil, Chile, China, Colombia, Czech Republic, Greece, Hungary, India, Indonesia, Malaysia, Mexico, Morocco, Peru, the Philippines, Poland, Russia, South Africa, Taiwan, Thailand, Turkey, the United Arab Emirates and Vietnam). The Fund also may invest in securities issued in accordance with Rule 144A (“Rule 144A securities”) and Regulation S (“Regulation S securities”) under the Securities Act of 1933, as amended (the “Securities Act”). Transactions in U.S. government agency mortgage-backed securities may occur through standardized agreements for forward or future delivery in which the actual mortgage pools to be delivered are not specified until shortly prior to settlement (to be announced (“TBA”) transactions). The Fund may engage in such TBA transactions.

As of August 31, 2019, the Underlying Index was comprised of 825 constituents.

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. A “sampling” methodology means that the Adviser uses a quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that have, in the aggregate, investment characteristics similar to the Underlying Index in terms of key risk factors, performance attributes and other characteristics.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 changes to 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 Investment Risk. Investments in the securities of issuers in emerging market countries involve risks often not associated with investments in the securities of issuers in developed countries. Securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets. Fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in emerging market securities, and emerging market securities may have relatively low market liquidity, decreased publicly available 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. Emerging market securities also are subject to the risks of expropriation, nationalization or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in emerging market securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions. Emerging markets usually are subject to greater market volatility, lower trading volume, political and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Securities law in many emerging market countries is relatively new and unsettled. Therefore, laws regarding foreign investment in emerging market securities, securities regulation, title to securities, and shareholder rights may change quickly and unpredictably. In addition, the enforcement of systems of taxation at federal, regional and local levels in emerging market countries may be inconsistent and subject to sudden change.

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 Fixed-Income Investment Risk. Investments in fixed income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

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. In addition, TBA transactions involve the risk that the securities received may be less favorable than what was anticipated by the Fund when entering into the TBA transaction, as well as counterparty risk. Default or bankruptcy of a counterparty to a TBA transaction would expose the Fund to potential loss and could affect the Fund’s returns.

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 and unrated securities of comparable credit quality are considered speculative and 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

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.

Performance

The Fund commenced operations on December 4, 2018 and therefore does not yet have a full calendar year of performance history. Once the Fund has a full calendar year of performance information, the Fund will present total return information, which is also accessible on the Fund’s website at www.invesco.com/ETFs and provides some indication of the risks of investing in the Fund.

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 and American depositary receipts (“ADRs”) and global depositary receipts (“GDRs”) that are based on securities in 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 measure the performance of equity securities issued by higher quality, small-business-sized companies located in countries designated as developed market countries (excluding the U.S.). 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 Index Provider selects components for inclusion in the Underlying Index from an investment universe of foreign equity securities with at least one year of trading history, issued by companies located in countries designated as developed market countries (excluding the U.S.). Each eligible equity security is assigned a business-size score (“Business-Size Score”) based on the equally-weighted average of the following four factors of company size over the prior five years (or, if shorter, the life of the security): sales, operating cash flow, total return of capital (dividends and share repurchases) and book value. For real estate securities (real estate investment trusts (“REITs”) and common stocks of companies in the real estate sector), operating cash flow is replaced by funds from operations and book value is replaced by total assets. Each eligible security is then assigned a quality score (“Quality Score”) based on the equally-weighted average of the following two quality factors of its company’s business: efficiency (calculated as the ratio of sales-to assets in the prior year) and growth (calculated as the percentage change in the ratio of sales-to-assets over the prior five years (or, if shorter, the life of the security)). Each eligible security is ranked in descending order by its Business-Size Score. Those securities ranked below 90% by Business-Size Score are eligible for inclusion in the Underlying Index and, of those, the 80% with the highest Quality Scores are included in the Underlying Index. Securities in the Underlying Index are weighted based on their float-adjusted Business-Size Scores. As of August 31, 2019, the following countries were classified as developed markets (excluding the U.S.) by the Index Provider: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, Luxembourg, the Netherlands, New Zealand, Norway, Portugal, Singapore, South Korea, Spain, Sweden, Switzerland, and United Kingdom. As of August 31, 2019, the Underlying Index was comprised of 1,939 constituents. The Fund employs a “full replication” methodology in seeking to track the Underlying Index, meaning that the Fund generally invests in all of the securities comprising the Underlying Index in proportion to their weightings in the Underlying Index. 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 August 31, 2019, the Fund had significant exposure to the industrials 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. ADR and GDR Risk. ADRs are certificates that evidence ownership of shares of a foreign issuer and are alternatives to purchasing the underlying foreign securities directly in their national markets and currencies. GDRs are certificates issued by an international bank that generally are traded and denominated in the currencies of countries other than the home country of the issuer of the underlying shares. ADRs and GDRs may be subject to certain of the risks associated with direct investments in the securities of foreign companies, such as currency, political, economic and market risks, because their values depend on the performance of the non-dollar denominated underlying foreign securities. Moreover, ADRs and GDRs may not track the price of the underlying foreign securities on which they are based, and their value may change materially at times when U.S. markets are not open for trading. 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar. Generally, an increase in the value of the U.S. dollar against a foreign currency will reduce the value of a security denominated in that foreign currency, thereby decreasing the Fund’s overall NAV. Exchange rates may be volatile and may change quickly and unpredictably in response to both global economic developments and economic conditions, causing an adverse impact on the Fund. As a result, investors have the potential for losses regardless of the length of time they intend to hold Shares. Equity Risk. Equity risk is the risk that the value of equity securities, including common stocks, may fall due to both changes in general economic conditions that impact the market as a whole, as well as factors that directly relate to a specific company or its industry. Such general economic conditions include changes in interest rates, periods of market turbulence or instability, or general and prolonged periods of economic decline and cyclical change. It is possible that a drop in the stock market may depress the price of most or all of the common stocks that the Fund holds. In addition, equity risk includes the risk that investor sentiment toward one or more industries will become negative, resulting in those investors exiting their investments in those industries, which could cause a reduction in the value of companies in those industries more broadly. The value of a company’s common stock may fall solely because of factors, such as an increase in production costs, that negatively impact other companies in the same region, industry or sector of the market. A company’s common stock also may decline significantly in price over a short period of time due to factors specific to that company, including decisions made by its management or lower demand for the company’s products or services. For example, an adverse event, such as an unfavorable earnings report or the failure to make anticipated dividend payments, may depress the value of common stock. 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. As the Fund will invest in securities denominated in foreign currencies, fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in foreign securities and may negatively impact the Fund’s returns. Geographic Concentration Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in that specific geographic region and adversely impact the Fund’s investments in the affected region. Risk of Investing in Japan. The Fund may invest a significant portion of its total assets in securities of issuers from Japan. The growth of Japan’s economy has recently lagged that of its Asian neighbors and other major developed economies. The Japanese economy is heavily dependent on international trade and has been adversely affected by trade tariffs, other protectionist measures, competition from emerging economies and the economic conditions of its trading partners. During the recent global recession, the Japanese economy experienced the effects of the economic slowdown in the United States and Europe. The Japanese economy also faces several other concerns, including a financial system with large levels of nonperforming loans, over-leveraged corporate balance sheets, extensive cross-ownership by major corporations, a changing corporate governance structure, and large government deficits. These issues may cause a continued slowdown of the Japanese economy. 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole. Industrials Sector Risk. Changes in government regulation, world events and economic conditions may adversely affect companies in the industrials sector. In addition, these companies are at risk for environmental and product liability damage claims. Also, commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources, technological developments and labor relations could adversely affect the companies in this sector. 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. Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares, or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. 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. 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. REIT Risk. REITs are subject to risks inherent in the direct ownership of real estate. These risks include, but are not limited to, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. REITs may be affected by changes in the values of the underlying properties that they own or operate and could fail to qualify for favorable tax or regulatory treatment. REITs also are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs rely heavily on cash flows and a variety of economic and other factors may adversely affect a lessee’s ability to meet its obligations to a REIT. Should a lessee default on their loan, the REIT may experience delays in enforcing its rights as a lessor and may incur substantial costs associated in protecting its investments. Small- and Mid-Capitalization Company Risk. Investing in securities of small- and mid-capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies’ securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often small- and mid-capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. 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 securities and, because foreign exchanges may be open on days when the Fund does not price its Shares, the value of those 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 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.

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 and American depositary receipts (“ADRs”) and global depositary receipts (“GDRs”) that are based on securities in 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 measure the performance of equity securities issued by higher quality, large-business-sized companies located in countries designated as emerging market countries. 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 Index Provider selects components for inclusion in the Underlying Index from an investment universe of foreign equity securities with at least one year of trading history, issued by companies located in countries designated as emerging market countries. Each eligible equity security is assigned a business-size score (“Business-Size Score”) based on the equally-weighted average of the following four factors of company size over the prior five years (or, if shorter, the life of the security): sales, operating cash flow, total return of capital (dividends and share repurchases) and book value.

ADRs are certificates that evidence ownership of shares of a foreign issuer and are alternatives to purchasing the underlying foreign securities directly in their national markets and currencies. GDRs are certificates issued by an international bank that generally are traded and denominated in the currencies of countries other than the home country of the issuer of the underlying shares.

Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. China Exposure Risk. The value of securities of companies that derive the majority of their revenues from China is likely to be more volatile than that of other issuers. The economy of China differs, often unfavorably, from the U.S. economy in such respects as structure, general development, government involvement, wealth distribution, rate of inflation, growth rate, allocation of resources and capital reinvestment. The Chinese central government historically has exercised substantial control over virtually every sector of the Chinese economy through administrative regulation and/or state ownership. Actions of the Chinese government authorities continue to have a substantial effect on economic conditions in China. It is difficult for non-Chinese investors to directly access securities in China because of investment and trading restrictions. These limitations and restrictions may impact the availability, liquidity, and pricing of certain securities. Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar. Generally, an increase in the value of the U.S. dollar against a foreign currency will reduce the value of a security denominated in that foreign currency, thereby decreasing the Fund’s overall NAV. Exchange rates may be volatile and may change quickly and unpredictably in response to both global economic developments and economic conditions, causing an adverse impact on the Fund. As a result, investors have the potential for losses regardless of the length of time they intend to hold Shares. Emerging Markets Investment Risk. Investments in the securities of issuers in emerging market countries involve risks often not associated with investments in the securities of issuers in developed countries. Securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets. Fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in emerging market securities, and emerging market securities may have relatively low market liquidity, decreased publicly available 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. Emerging market securities also are subject to the risks of expropriation, nationalization or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in emerging market securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions. Emerging markets are subject to greater market volatility, lower trading volume, political and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than are more developed markets. Securities law in many emerging market countries is relatively new and unsettled. Therefore, laws regarding foreign investment in emerging market securities, securities regulation, title to securities, and shareholder rights may change quickly and unpredictably. In addition, the enforcement of systems of taxation at federal, regional and local levels in emerging market countries may be inconsistent and subject to sudden change. Equity Risk. Equity risk is the risk that the value of equity securities, including common stocks, may fall due to both changes in general economic conditions that impact the market as a whole, as well as factors that directly relate to a specific company or its industry. Such general economic conditions include changes in interest rates, periods of market turbulence or instability, or general and prolonged periods of economic decline and cyclical change. It is possible that a drop in the stock market may depress the price of most or all of the common stocks that the Fund holds. In addition, equity risk includes the risk that investor sentiment toward one or more industries will become negative, resulting in those investors exiting their investments in those industries, which could cause a reduction in the value of companies in those industries more broadly. The value of a company’s common stock may fall solely because of factors, such as an increase in production costs, that negatively impact other companies in the same region, industry or sector of the market. A company’s common stock also may decline significantly in price over a short period of time due to factors specific to that company, including decisions made by its management or lower demand for the company’s products or services. For example, an adverse event, such as an unfavorable earnings report or the failure to make anticipated dividend payments, may depress the value of common stock. 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. As the Fund will invest in securities denominated in foreign currencies, fluctuations in the value of the U.S. dollar relative to the values of other currencies may adversely affect investments in foreign securities and may negatively impact the Fund’s returns. Geographic Concentration Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in that specific geographic region and adversely impact the Fund’s investments in the affected region. 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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. Large Shareholder Risk. Certain shareholders, including a third party investor, the Fund’s investment adviser or an affiliate of the investment adviser, an AP, a lead market maker, or another entity, may from time to time own a substantial amount of Shares, or may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. Similarly, to the extent the Fund permits cash purchases, large purchases of Shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Exchange and may, therefore, have a material upward or downward effect on the market price of the Shares. To the extent the Fund permits redemptions in cash, the Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. 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. Mid-Capitalization Company Risk. Investing in securities of mid-capitalization companies involves greater risk than is customarily associated with investing in larger, more established companies. These companies’ securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Often mid-capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. 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. 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. REIT Risk. REITs are subject to risks inherent in the direct ownership of real estate. These risks include, but are not limited to, a possible lack of mortgage funds and associated interest rate risks, overbuilding, property vacancies, increases in property taxes and operating expenses, changes in zoning laws, losses due to environmental damages and changes in neighborhood values and appeal to purchasers. REITs may be affected by changes in the values of the underlying properties that they own or operate and could fail to qualify for favorable tax or regulatory treatment. REITs also are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs rely heavily on cash flows and a variety of economic and other factors may adversely affect a lessee’s ability to meet its obligations to a REIT. Should a lessee default on their loan, the REIT may experience delays in enforcing its rights as a lessor and may incur substantial costs associated in protecting its investments. 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 securities and, because foreign exchanges may be open on days when the Fund does not price its Shares, the value of those 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 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.

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 86% of the average value of its portfolio.

Strategy [Heading]

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated high yield corporate bonds (commonly known as “junk bonds”) with maturities or, in some cases, “effective maturities” in the year 2020 (collectively, “2020 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) have a maximum rating of BB+ from S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or a maximum rating of Ba1 from Moody’s Investors Service, Inc. (“Moody’s”); (iii) have a minimum average credit rating (computed by calculating the simple average of a bond’s rating published by S&P, Fitch and Moody’s and then rounding down to the nearest rating step) of CCC- from S&P, Fitch and Moody’s; and (iv) have at least $200 million in face value outstanding (existing bonds in the eligible universe require $150 million in face value outstanding to remain eligible).

The eligible universe may include securities issued in accordance with Rule 144A under the Securities Act of 1933, as amended (“Securities Act”).

2020 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 76 constituents.

The Fund will terminate on or about December 15, 2020. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2020), no new constituents are added and the Underlying Index does not rebalance. In the last twelve months of operation, when the 2020 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2020 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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 may 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.

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.

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.

[1] “Acquired Fund Fees and Expenses” are indirect fees and expenses that the Fund incurs from investing in the shares of other investment companies (including money market funds). These expenses are based on the total expense ratio of the underlying funds disclosed in each underlying fund’s most recent shareholder report. Please note that the amount of “Total Annual Fund Operating Expenses” shown in the above table differs from the ratio of expenses to average net assets included in the “Financial Highlights” section of this Prospectus, which reflects the operating expenses of the Fund and does not include indirect expenses such as Acquired Fund Fees and Expenses.

[2] Through August 31, 2021, Invesco Capital Management LLC (the “Adviser”) has contractually agreed to waive a portion of the Fund’s management fee in an amount equal to 100% of the net advisory fees an affiliate of the Adviser receives that are attributable to certain of the Fund’s investments in money market funds managed by that affiliate. This waiver will have the effect of reducing the Acquired Fund Fees and Expenses that are indirectly borne by the Fund. The Adviser cannot discontinue this waiver prior to its expiration.

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 52% of the average value of its portfolio.

Strategy [Heading]

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated high yield corporate bonds (commonly known as “junk bonds”) with maturities or, in some cases, “effective maturities” in the year 2021 (collectively, “2021 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) have a maximum rating of BB+ from S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or a maximum rating of Ba1 from Moody’s Investors Service, Inc. (“Moody’s”); (iii) have a minimum average credit rating (computed by calculating the simple average of a bond’s rating published by S&P, Fitch and Moody’s and then rounding down to the nearest rating step) of CCC- from S&P, Fitch and Moody’s; and (iv) have at least $200 million in face value outstanding (existing bonds in the eligible universe require $150 million in face value outstanding to remain eligible).

The eligible universe may include securities issued in accordance with Rule 144A under the Securities Act of 1933, as amended (“Securities Act”).

2021 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 122 constituents.

The Fund will terminate on or about December 15, 2021. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2021), no new constituents are added and the Underlying Index does not rebalance. In the last twelve months of operation, when the 2021 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2021 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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 may 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.

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.

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 BulletShares 2023 Corporate Bond ETF

Invesco BulletShares 2023 Corporate Bond ETF Summary Information

Investment Objective

The Invesco BulletShares 2023 Corporate Bond ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Nasdaq BulletShares^® USD Corporate Bond 2023 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 BulletShares 2023 Corporate Bond ETF Invesco BulletShares 2023 Corporate Bond ETF
Management Fees	0.10%
Other Expenses	none
Total Annual Fund Operating Expenses	0.10%

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	5 Years	10 Years
Invesco BulletShares 2023 Corporate Bond ETF | Invesco BulletShares 2023 Corporate Bond ETF | USD ($)	10	32	57	128

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 6% of the average value of its portfolio.

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated investment grade corporate bonds with maturities or, in some cases, “effective maturities” in the year 2023 (collectively, “2023 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) be rated at least BBB- by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or at least Baa3 by Moody’s Investors Service, Inc. (“Moody’s”); and (iii) have at least $500 million in face value outstanding (existing bonds in the eligible universe require $400 million in face value outstanding to remain eligible).

2023 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 313 constituents.

The Fund will terminate on or about December 15, 2023. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2023), no new constituents are added and the Underlying Index rebalances only through June. In the last six months of operation, when the 2023 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2023 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates, 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Sampling Risk. The Fund’s use of a representative sampling approach may 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.

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.

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.

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.

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 seeks to measure the performance of a portfolio of U.S. dollar-denominated investment grade corporate bonds with maturities or, in some cases, “effective maturities” in the year 2025 (collectively, “2025 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) be rated at least BBB- by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or at least Baa3 by Moody’s Investors Service, Inc. (“Moody’s”); and (iii) have at least $500 million in face value outstanding (existing bonds in the eligible universe require $400 million in face value outstanding to remain eligible).

2025 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 234 constituents.

The Fund will terminate on or about December 15, 2025. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2025), no new constituents are added and the Underlying Index rebalances only through June. In the last six months of operation, when the 2025 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2025 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates, are likely to change over time.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Sampling Risk. The Fund’s use of a representative sampling approach may 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.

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 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 BulletShares 2020 High Yield Corporate Bond ETF

Invesco BulletShares 2020 High Yield Corporate Bond ETF Summary Information

Investment Objective

The Invesco BulletShares 2020 High Yield Corporate Bond ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Nasdaq BulletShares^® USD High Yield Corporate Bond 2020 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 BulletShares 2020 High Yield Corporate Bond ETF Invesco BulletShares 2020 High Yield Corporate Bond ETF
Management Fees	0.42%
Other Expenses	none
Acquired Fund Fees and Expenses	0.01%	[1]
Total Annual Fund Operating Expenses	0.43%
Fee Waivers and/or Expense Reimbursement	0.01%	[2]
Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursement	0.42%

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 are equal to the Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursement in the first year, and the Total Annual Fund Operating Expenses for periods thereafter. 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	5 Years	10 Years
Invesco BulletShares 2020 High Yield Corporate Bond ETF | Invesco BulletShares 2020 High Yield Corporate Bond ETF | USD ($)	43	137	240	541

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 86% of the average value of its portfolio.

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated high yield corporate bonds (commonly known as “junk bonds”) with maturities or, in some cases, “effective maturities” in the year 2020 (collectively, “2020 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) have a maximum rating of BB+ from S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or a maximum rating of Ba1 from Moody’s Investors Service, Inc. (“Moody’s”); (iii) have a minimum average credit rating (computed by calculating the simple average of a bond’s rating published by S&P, Fitch and Moody’s and then rounding down to the nearest rating step) of CCC- from S&P, Fitch and Moody’s; and (iv) have at least $200 million in face value outstanding (existing bonds in the eligible universe require $150 million in face value outstanding to remain eligible).

The eligible universe may include securities issued in accordance with Rule 144A under the Securities Act of 1933, as amended (“Securities Act”).

2020 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 76 constituents.

The Fund will terminate on or about December 15, 2020. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2020), no new constituents are added and the Underlying Index does not rebalance. In the last twelve months of operation, when the 2020 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2020 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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 may 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.

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

The bar chart below shows how the Fund has performed. The table below the bar chart shows the Fund’s average annual total returns (before and after taxes). The bar chart and table provide an indication of the risks of investing in the Fund by showing how the Fund’s total returns have varied from year to year and by showing how the Fund’s average annual total returns compared with a broad measure of market performance and an additional index with characteristics relevant to the Fund. Although the information shown in the bar chart and the table gives you some idea of the risks involved in investing in the Fund, the Fund’s past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future.

The Fund is the successor to the investment performance of the Guggenheim BulletShares 2020 High Yield Corporate Bond ETF (the “Predecessor Fund”) as a result of the reorganization of the Predecessor Fund into the Fund, which was consummated after the close of business on April 6, 2018. Accordingly, the performance information shown below for periods ending on or prior to April 6, 2018 is that of the Predecessor Fund.

Invesco BulletShares 2023 High Yield Corporate Bond ETF

Invesco BulletShares 2023 High Yield Corporate Bond ETF Summary Information

Investment Objective

The Invesco BulletShares 2023 High Yield Corporate Bond ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Nasdaq BulletShares^® USD High Yield Corporate Bond 2023 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 BulletShares 2023 High Yield Corporate Bond ETF Invesco BulletShares 2023 High Yield Corporate Bond ETF
Management Fees	0.42%
Other Expenses	none
Total Annual Fund Operating Expenses	0.42%

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	5 Years	10 Years
Invesco BulletShares 2023 High Yield Corporate Bond ETF | Invesco BulletShares 2023 High Yield Corporate Bond ETF | USD ($)	43	135	235	530

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 19% of the average value of its portfolio.

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated high yield corporate bonds (commonly known as “junk bonds”) with maturities or, in some cases, “effective maturities” in the year 2023 (collectively, “2023 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) have a maximum rating of BB+ from S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or a maximum rating of Ba1 from Moody’s Investors Service, Inc. (“Moody’s”); (iii) have a minimum average credit rating (computed by calculating the simple average of a bond’s rating published by S&P, Fitch and Moody’s and then rounding down to the nearest rating step) of CCC- from S&P, Fitch and Moody’s; and (iv) have at least $200 million in face value outstanding (existing bonds in the eligible universe require $150 million in face value outstanding to remain eligible).

The eligible universe may include securities issued in accordance with Rule 144A under the Securities Act of 1933, as amended (“Securities Act”).

2023 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 207 constituents.

The Fund will terminate on or about December 15, 2023. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2023), no new constituents are added and the Underlying Index does not rebalance. In the last twelve months of operation, when the 2023 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2023 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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 may 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.

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

The bar chart below shows how the Fund has performed. The table below the bar chart shows the Fund’s average annual total returns (before and after taxes). The bar chart and table provide an indication of the risks of investing in the Fund by showing how the Fund’s total returns have varied from year to year and by showing how the Fund’s average annual total returns compared with a broad measure of market performance and an additional index with characteristics relevant to the Fund. Although the information shown in the bar chart and the table gives you some idea of the risks involved in investing in the Fund, the Fund’s past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future.

The Fund is the successor to the investment performance of the Guggenheim BulletShares 2023 High Yield Corporate Bond ETF (the “Predecessor Fund”) as a result of the reorganization of the Predecessor Fund into the Fund, which was consummated after the close of business on April 6, 2018. Accordingly, the performance information shown below for periods ending on or prior to April 6, 2018 is that of the Predecessor Fund.

Invesco Defensive Equity ETF

Invesco Defensive Equity ETF Summary Information

Investment Objective

The Invesco Defensive Equity ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Invesco Defensive Equity 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 Defensive Equity ETF Invesco Defensive Equity ETF
Management Fees	0.50%
Other Expenses	0.05%
Total Annual Fund Operating Expenses	0.55%

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	5 Years	10 Years
Invesco Defensive Equity ETF | Invesco Defensive Equity ETF | USD ($)	56	176	307	689

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 145% of the average value of its portfolio.

Principal Investment Strategies

The Fund generally will invest at least 80% of its total assets in the securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, Invesco Indexing LLC (“Invesco Indexing” or the “Index Provider”) compiles and maintains the Underlying Index, which is comprised of a subset of securities from the S&P 500^® Index (the “S&P 500”). 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”).

Instead of the traditional approach to defensive equity portfolios that focuses solely on low beta stocks, the Underlying Index, using a rules-based quantitative approach, is designed to measure the performance of approximately 100 equal-weighted securities selected from the S&P 500 based on (i) the probability of delivering the required revenue growth to support the current stock price, (ii) beta (a measure of a given security’s volatility in relation to the volatility of a specific market) and (iii) down market volatility (a measurement that represents a security’s volatility during adverse market conditions). For each security in the S&P 500, the probability of delivering the required revenue growth to support the current stock price is calculated. The securities in the top 80% based on their probability scores are eligible for inclusion in the Underlying Index. Of those securities, the 75% with the lowest beta are further evaluated and those that rank in the bottom 50% on down market volatility are eligible for inclusion in the Underlying Index. Of those securities, the 100 securities with a higher probability of delivering the required revenue growth to support their current stock prices while minimizing any differences in industry exposure relative to the S&P 500 are included in the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 100 securities with market capitalizations ranging from $5.7 billion to $365.4 billion.

The Fund employs a “full replication” methodology in seeking to track the Underlying Index, meaning that the Fund generally invests in all of the securities comprising the Underlying Index in proportion to their weightings in the Underlying Index.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

Equity Risk. Equity risk is the risk that the value of equity securities, including common stocks, may fall due to both changes in general economic conditions that impact the market as a whole, as well as factors that directly relate to a specific company or its industry. Such general economic conditions include changes in interest rates, periods of market turbulence or instability, or general and prolonged periods of economic decline and cyclical change. It is possible that a drop in the stock market may depress the price of most or all of the common stocks that the Fund holds. In addition, equity risk includes the risk that investor sentiment toward one or more industries will become negative, resulting in those investors exiting their investments in those industries, which could cause a reduction in the value of companies in those industries more broadly. The value of a company’s common stock may fall solely because of factors, such as an increase in production costs, that negatively impact other companies in the same region, industry or sector of the market. A company’s common stock also may decline significantly in price over a short period of time due to factors specific to that company, including decisions made by its management or lower demand for the company’s products or services. For example, an adverse event, such as an unfavorable earnings report or the failure to make anticipated dividend payments, may depress the value of common stock.

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

Industry Concentration Risk. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

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. 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Portfolio Turnover Risk. The Fund may engage in frequent trading of its portfolio securities in connection with the rebalancing or adjustment of the Underlying Index. A portfolio turnover rate of 200%, for example, is equivalent to the Fund buying and selling all of its securities two times during the course of a year. A high portfolio turnover rate (such as 100% or more) could result in high brokerage costs for the Fund. While a high portfolio turnover rate can result in an increase in taxable capital gain distributions to the Fund’s shareholders, the Fund will seek to utilize the in-kind creation and redemption mechanism (described below) to minimize realization of capital gains to the extent possible.

Quantitative Investment Strategy Risk. The factors used in the Underlying Index model’s quantitative analysis and the weight placed on these factors may not accurately predict a security’s value. As a result, the Fund may have a lower return than if the Fund tracked an index based on a fundamental investment strategy, or an index that did not incorporate quantitative analysis.

Performance

The bar chart and table provide an indication of the risks of investing in the Fund by showing how the Fund’s total returns have varied from year to year and by showing how the Fund’s average annual total return compared with a broad measure of market performance and an additional index with characteristics relevant to the Fund.

The Fund’s performance reflects fee waivers, if any, absent which performance would have been lower. Although the information shown in the bar chart and the table gives you some idea of the risks involved in investing in the Fund, the Fund’s past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future.

The Fund is the successor to the investment performance of the Guggenheim Defensive Equity ETF (the “Predecessor Fund”) as a result of the reorganization of the Predecessor Fund into the Fund, which was consummated after the close of business on April 6, 2018.

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 5% of the average value of its portfolio.

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.

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 seeks to measure the performance of a portfolio of U.S. dollar-denominated investment grade corporate bonds with maturities or, in some cases, “effective maturities” in the year 2024 (collectively, “2024 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) be rated at least BBB- by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or at least Baa3 by Moody’s Investors Service, Inc. (“Moody’s”); and (iii) have at least $500 million in face value outstanding (existing bonds in the eligible universe require $400 million in face value outstanding to remain eligible).

2024 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 244 constituents.

The Fund will terminate on or about December 15, 2024. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2024), no new constituents are added and the Underlying Index rebalances only through June. In the last six months of operation, when the 2024 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2024 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates, 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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Sampling Risk. The Fund’s use of a representative sampling approach may 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.

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

The bar chart below shows how the Fund has performed. The table below the bar chart shows the Fund’s average annual total returns (before and after taxes). The bar chart and table provide an indication of the risks of investing in the Fund by showing how the Fund’s total returns have varied from year to year and by showing how the Fund’s average annual total returns compared with a broad measure of market performance and an additional index with characteristics relevant to the Fund. Although the information shown in the bar chart and the table gives you some idea of the risks involved in investing in the Fund, the Fund’s past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future.

The Fund is the successor to the investment performance of the Guggenheim BulletShares 2024 Corporate Bond ETF (the “Predecessor Fund”) as a result of the reorganization of the Predecessor Fund into the Fund, which was consummated after the close of business on April 6, 2018. Accordingly, the performance information shown below for periods ending on or prior to April 6, 2018 is that of the Predecessor Fund.

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 22% of the average value of its portfolio.

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated high yield corporate bonds (commonly known as “junk bonds”) with maturities or, in some cases, “effective maturities” in the year 2024 (collectively, “2024 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) have a maximum rating of BB+ from S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or a maximum rating of Ba1 from Moody’s Investors Service, Inc. (“Moody’s”); (iii) have a minimum average credit rating (computed by calculating the simple average of a bond’s rating published by S&P, Fitch and Moody’s and then rounding down to the nearest rating step) of CCC- from S&P, Fitch and Moody’s; and (iv) have at least $200 million in face value outstanding (existing bonds in the eligible universe require $150 million in face value outstanding to remain eligible).

The eligible universe may include securities issued in accordance with Rule 144A under the Securities Act of 1933, as amended (“Securities Act”).

2024 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 197 constituents.

The Fund will terminate on or about December 15, 2024. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2024), no new constituents are added and the Underlying Index does not rebalance. In the last twelve months of operation, when the 2024 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2024 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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]

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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 may 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.

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.

Although the information shown in the bar chart and the table gives you some idea of the risks involved in investing in the Fund, the Fund’s past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future.

The Fund is the successor to the investment performance of the Guggenheim BulletShares 2024 High Yield Corporate Bond ETF (the “Predecessor Fund”) as a result of the reorganization of the Predecessor Fund into the Fund, which was consummated after the close of business on April 6, 2018. Accordingly, the performance information shown below for periods ending on or prior to April 6, 2018 is that of the Predecessor Fund. Updated performance information is available online at www.invesco.com/ETFs.

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated investment grade corporate bonds with maturities or, in some cases, “effective maturities” in the year 2028 (collectively, “2028 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date. In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) be rated at least BBB- by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or at least Baa3 by Moody’s Investors Service, Inc. (“Moody’s”); and (iii) have at least $500 million in face value outstanding (existing bonds in the eligible universe require $400 million in face value outstanding to remain eligible). 2028 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index. As of August 31, 2019, the Underlying Index was comprised of 145 constituents. The Fund will terminate on or about December 15, 2028. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2028), no new constituents are added and the Underlying Index rebalances only through June. In the last six months of operation, when the 2028 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2028 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time. 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.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk. 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 exercises 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 changes to 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. Declining Yield Risk. During the final year of the Fund’s operations, as the bonds held by the Fund mature and the Fund’s portfolio transitions to cash and cash equivalents, the Fund’s yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market. 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. Fluctuation of Yield and Liquidation Amount Risk. The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in corporate bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes. Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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. 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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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. Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. Sampling Risk. The Fund’s use of a representative sampling approach may 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. 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.

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 seeks to measure the performance of a portfolio of U.S. dollar-denominated investment grade corporate bonds with maturities or, in some cases, “effective maturities” in the year 2027 (collectively, “2027 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) be rated at least BBB- by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or at least Baa3 by Moody’s Investors Service, Inc. (“Moody’s”); and (iii) have at least $500 million in face value outstanding (existing bonds in the eligible universe require $400 million in face value outstanding to remain eligible).

2027 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 211 constituents.

The Fund will terminate on or about December 15, 2027. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2027), no new constituents are added and the Underlying Index rebalances only through June. In the last six months of operation, when the 2027 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2027 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates, are likely to change over time.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Sampling Risk. The Fund’s use of a representative sampling approach may 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.

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 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 BulletShares 2025 High Yield Corporate Bond ETF

Invesco BulletShares 2025 High Yield Corporate Bond ETF Summary Information

Investment Objective

The Invesco BulletShares 2025 High Yield Corporate Bond ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Nasdaq BulletShares^® USD High Yield Corporate Bond 2025 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 BulletShares 2025 High Yield Corporate Bond ETF Invesco BulletShares 2025 High Yield Corporate Bond ETF
Management Fees	0.42%
Other Expenses	none	[1]
Total Annual Fund Operating Expenses	0.42%

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	5 Years	10 Years
Invesco BulletShares 2025 High Yield Corporate Bond ETF | Invesco BulletShares 2025 High Yield Corporate Bond ETF | USD ($)	43	135	235	530

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 Total Annual Fund Operating Expenses or in the example, may affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate of the Fund was 14% of the average value of its portfolio.

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. 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 seeks to measure the performance of a portfolio of U.S. dollar-denominated high yield corporate bonds (commonly known as “junk bonds”) with maturities or, in some cases, “effective maturities” in the year 2025 (collectively, “2025 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) have a maximum rating of BB+ from S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or a maximum rating of Ba1 from Moody’s Investors Service, Inc. (“Moody’s”); (iii) have a minimum average credit rating (computed by calculating the simple average of a bond’s rating published by S&P, Fitch and Moody’s and then rounding down to the nearest rating step) of CCC- from S&P, Fitch and Moody’s; and (iv) have at least $200 million in face value outstanding (existing bonds in the eligible universe require $150 million in face value outstanding to remain eligible).

The eligible universe may include securities issued in accordance with Rule 144A under the Securities Act of 1933, as amended (“Securities Act”).

2025 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 249 constituents.

The Fund will terminate on or about December 15, 2025. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2025), no new constituents are added and the Underlying Index does not rebalance. In the last twelve months of operation, when the 2025 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2025 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups 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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. 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 may 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.

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

The bar chart below shows how the Fund has performed. The table below the bar chart shows the Fund’s average annual total returns (before and after taxes). The table provides an indication of the risks of investing in the Fund by showing how the Fund’s average annual total returns compared with a broad measure of market performance and an additional index with characteristics relevant to the Fund. Although the information shown in the bar chart and the table gives you some idea of the risks involved in investing in the Fund, the Fund’s past performance (before and after taxes) is not necessarily indicative of how the Fund will perform in the future.

The Fund is the successor to the investment performance of the Guggenheim BulletShares 2025 High Yield Corporate Bond ETF (the “Predecessor Fund”) as a result of the reorganization of the Predecessor Fund into the Fund, which was consummated after the close of business on May 18, 2018. Accordingly, the performance information shown below for the periods ending on or prior to May 18, 2018 is that of the Predecessor Fund.

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.

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 seeks to measure the performance of a portfolio of U.S. dollar-denominated investment grade corporate bonds with maturities or, in some cases, “effective maturities” in the year 2020 (collectively, “2020 Bonds”). Effective maturity is an assessment of a bond’s likely call date or maturity (if not called by the issuer). With respect to establishing the effective maturity of a bond, if no embedded issuer call option exists for a bond; then the Index Provider deems effective maturity to be the actual year of maturity. If a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; then the Index Provider also deems effective maturity to be the actual year of maturity. In other cases, the Index Provider deems effective maturity to be the actual year of maturity, unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the year of the next call date.

In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by companies domiciled in the U.S., Canada, Western Europe (as defined by the Index Provider) or Japan. To be eligible for inclusion in the Underlying Index, bonds must (i) pay a fixed amount of taxable interest; (ii) be rated at least BBB- by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”) or at least Baa3 by Moody’s Investors Service, Inc. (“Moody’s”); and (iii) have at least $500 million in face value outstanding (existing bonds in the eligible universe require $400 million in face value outstanding to remain eligible).

2020 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.

As of August 31, 2019, the Underlying Index was comprised of 373 constituents.

The Fund will terminate on or about December 15, 2020. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2020), no new constituents are added and the Underlying Index rebalances only through June. In the last six months of operation, when the 2020 Bonds held by the Fund mature, the Fund’s portfolio will transition to cash and cash equivalents, including without limitation U.S. Treasury Bills and investment grade commercial paper. The Fund will terminate on or about December 15, 2020 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.

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 August 31, 2019, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates, are likely to change over time.

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 APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by 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 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, and Shares may be more likely to trade at a premium or discount to the Fund’s net asset value (“NAV”) and to face trading halts and/or delisting. Investments in non-U.S. securities, which may have lower trading volumes, may increase this risk.

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 exercises 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 changes to 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.

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

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.

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

Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, 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.

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. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the industry or industry group. In addition, at times, such industry or industry group may be out of favor and underperform other industries, industry groups or the market as a whole.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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.

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.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the investment adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

Sampling Risk. The Fund’s use of a representative sampling approach may 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.

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.

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.
