Invesco Taxable Municipal Bond ETF (BAB) Exchange: NYSE ARCA

The Fund generally will invest at least 80% of its total assets in taxable municipal securities that comprise the Underlying Index. The Underlying Index is designed to track the performance of U.S. dollar-denominated taxable municipal debt publicly issued by U.S. states and territories, and their political subdivisions, in the U.S. market. Securities eligible for inclusion in the Underlying Index must have: (i) at least 18 months to final maturity at the time of issuance, (ii) at least one year remaining term to final maturity, (iii) a fixed coupon schedule, and (iv) an investment grade rating (based on an average of Moody’s Investors Services, Inc. (“Moody’s”), S&P Global Ratings (“S&P”) and Fitch Ratings, Inc. (“Fitch”). Component securities also must have a minimum amount outstanding that varies according to the bond’s initial term to final maturity at time of issuance: maturities between 1-5 years must have at least $10 million outstanding; maturities between 5-10 years must have at least $15 million outstanding; maturities of 10 years or more must have at least $25 million outstanding. The Underlying Index excludes Rule 144A securities and securities in default. However, it may include bonds eligible to participate in the Build America Bond program created under the American Recovery and Reinvestment Act of 2009 or other legislation providing for the issuance of taxable municipal securities on which the issuer receives federal support of the interest paid (“Build America Bonds”). Unlike most other municipal obligations, interest received on Build America Bonds is subject to federal and state income tax. Issuers of “direct pay” Build America Bonds (i.e., taxable municipal bonds issued to provide funds for qualified capital expenditures) are entitled to receive payments from the U.S. Treasury over the life of the bond equal to 35% (or 45% in the case of Recovery Zone Economic Development Bonds) of the interest paid. The federal interest subsidy continues for the life of the bonds. The Underlying Index does not include bonds that, under the Build America Bond program, are eligible for tax credits. Build America Bonds must have at least $1 million outstanding to be eligible for inclusion in the Underlying Index. ICE Data Indices, LLC (“ICE Data” or the “Index Provider”) uses a capitalization weighted methodology, weighting the Underlying Index’s constituent bonds using a factor that equals their current amount outstanding multiplied by their market price, plus accrued interest. As of August 31, 2019, the Underlying Index was comprised of 6,916 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. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total 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.
