Invesco BulletShares 2021 High Yield Corporate Bond ETF (BSJL) Exchange: NYSE ARCA

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.
