About TSSAX

Thornburg Strategic Municipal Income Fund Class A is an actively managed municipal bond mutual fund designed to deliver a high level of current income that is generally exempt from federal individual income tax. The fund primarily invests in a diversified portfolio of tax-exempt obligations issued by U.S. states, local governments, and their agencies, with an intermediate interest-rate profile typical of the muni national intermediate category. It seeks to balance income and risk through broad sector and geographic diversification across the municipal market, targeting effective durations in the intermediate range while managing credit quality and call features. The strategy is benchmarked to widely followed municipal bond indices and is overseen by a team of portfolio managers who allocate across revenue and general obligation bonds, essential services, healthcare, transportation, and other public-purpose sectors. Within the municipal bond landscape, the fund’s role is to provide tax-efficient income and core fixed income exposure for investors seeking federally tax-exempt distributions, while maintaining a focus on risk-adjusted returns consistent with intermediate-term municipal securities.
