The Invesco BulletShares 2028 Municipal Bond ETF (the Fund) is designed to track the performance of the Invesco BulletShares USD Municipal Bond 2028 Index. The Fund commits a minimum of 80% of its total assets to municipal debt instruments that are part of this benchmark index. The Index itself aims to reflect the returns of a diversified collection of U.S. dollar-denominated municipal securities, which are issued by U.S. states, their agencies, or local governmental bodies, and all possess an effective maturity date in 2028. Instead of acquiring every security within the Index, the Fund implements a "sampling" methodology to work towards its investment goals. Both the Fund's portfolio and the Index's composition undergo monthly adjustments. This Fund features a predetermined maturity year of 2028 and is scheduled to cease operations around December 15, 2028. For complete details, consult the prospectus.
