Investment objective & strategy

As of Feb. 26, 2026 · prospectus

Objective. The Fund seeks to provide current income that is generally exempt from federal income taxes, and long-term total return.

Strategy. The Fund seeks to achieve its investment objective by investing in investment grade and non-investment grade (known as junk bonds) municipal securities that the sub-adviser, Wellington Management Company LLP (Wellington Management), considers to be attractive from a yield perspective while considering total return. Under normal circumstances, at least 80% of the Funds net assets must be invested in municipal securities. The Fund may invest up to 20% of the Funds net assets in non-investment grade municipal securities. The Fund may invest in securities that produce income subject to income tax, including the Alternative Minimum Tax. The Fund will generally hold a diversified portfolio of investments across states and sectors, although the Fund is not required to invest in all states … The Fund seeks to achieve its investment objective by investing in investment grade and non-investment grade (known as junk bonds) municipal securities that the sub-adviser, Wellington Management Company LLP (Wellington Management), considers to be attractive from a yield perspective while considering total return.
