Strictly in accordance with its guidelines and mandated procedures, ICE Data Indices, LLC (the Index Provider) compiles, maintains and calculates the Underlying Index, which is designed to measure the performance of U.S. Treasury Obligations with a maximum remaining maturity of less than or equal to 12 months. U.S. Treasury Obligations refer to securities issued or guaranteed by the U.S. Treasury where the payment of principal and interest is backed by the full faith and credit of the U.S. government. They include U.S. Treasury notes, bills and bonds. The Fund expects to invest 100% of its total assets in cash and U.S. Treasury Obligations with a maximum remaining maturity of less than or equal to 12 months. The Underlying Index includes all publicly-issued, non-convertible U.S. Treasury Obligations that: (i) are issued in U.S. dollars, (ii) have a minimum remaining maturity greater than one month and a maximum remaining maturity of less than or equal to 12 months at the time of rebalance, (iii) have a fixed coupon schedule, and (iv) have a minimum adjusted amount outstanding of $300 million. The Underlying Index excludes inflation-linked debt securities, original issue zero coupon securities, any government agency debt issued with or without a government guarantee, securities issued or marketed primarily to retail investors and Separate Trading of Registered Interest and Principal of Securities (STRIPS). The Underlying Index uses a market capitalization-weighted methodology. As of October 31, 2025, the Underlying Index was comprised of 91 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. In managing the Fund, Invesco Advisers, Inc. (the Sub-Adviser) selects component securities that are expected to have, in the aggregate, investment characteristics, risk factors and liquidity measures that are similar to, and therefore are representative of the Underlying Index. The Fund is not a money market fund and does not attempt to maintain a stable net asset value. 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 U.S. government, state and municipal governments and their agencies, authorities and instrumentalities are not deemed to be industries for this purpose. Show less
