Effective March 22, 2024, the Fund’s broad-based benchmark is the Bloomberg Municipal Bond Index replacing the Bloomberg U.S. Aggregate Bond Index. The Bloomberg Municipal Bond Index is a market capitalization-weighted index that measures the long-term tax-exempt bond market and is more closely matched to the Fund’s principal investment strategy. Effective February 1, 2021, the ICE BofA 1-22 Year U.S. Municipal Securities Index is the Fund’s style-specific benchmark. The ICE BofA 1-22 Year U.S. Municipal Securities Index is a subset of the ICE BofA U.S. Municipal Securities Index including all securities with a remaining term to final maturity less than 22 years, calculated on a total return basis. The indexes are calculated on a total return basis, are unmanaged, and are not available for direct investment.
