The investment seeks to track the investment results (before fees and expenses) of the Invesco BulletShares® Municipal Bond 2022 Index.
The fund generally will invest at least 80% of its total assets in securities that comprise the underlying index. The underlying index is designed to measure the performance of a portfolio of U.S. dollar-denominated investment-grade municipal bonds with maturities in the year 2022 or, in some cases, "effective maturities" in the year 2022. It is non-diversified.
