Performance shown prior to the inception date is that of the Fund’s Class A shares at net asset value and includes the 12b-1 fees applicable to that class. Although invested in the same portfolio of securities, Class R6 shares’ returns of the Fund will be different from Class A shares’ returns of the Fund as they have different expenses.
2
Effective April 1, 2024, the Fund changed its broad-based securities market benchmark from the Bloomberg U.S. Aggregate Bond Index to the S&P Municipal Bond Index. The Fund had previously changed its broad-based securities market benchmark from the S&P Municipal Bond High Yield Index to the Bloomberg U.S. Aggregate Bond Index in December 2023. The Fund believes the S&P Municipal Bond Index is a more appropriate comparison for evaluating the Fund’s performance.

The Custom Invesco Short Duration High Yield Municipal Index is composed of 60% S&P Municipal Bond High Yield Index and 40% S&P Municipal Bond Short Index.
