The Invesco BulletShares 2034 Municipal Bond ETF seeks to track the performance of the Invesco BulletShares USD Municipal Bond 2034 Index. To achieve this, the Fund commits at least 80% of its portfolio to municipal bonds that are included in this index. The underlying Index is designed to measure the returns of a collection of US dollar-denominated municipal securities, which have been issued by American state, state agency, or local governments and are slated to mature in 2034.
