About THMIX

Thornburg Intermediate Municipal Fund Class I is a municipal bond mutual fund managed by Thornburg, designed to provide high levels of income that is exempt from federal individual income tax. The fund primarily invests in a diversified portfolio of intermediate-term municipal securities issued by states and local governments across the United States to fund public projects. Its investment strategy focuses on maintaining a laddered maturity structure, which seeks to balance income generation with reduced share price volatility and preservation of capital. With an effective duration of approximately 5.2 years, the fund targets holdings with average maturities in the intermediate range, thereby managing sensitivity to interest rate fluctuations. The portfolio is broadly diversified across sectors such as public energy authorities, housing finance, and economic development agencies. The fund is actively managed and distinguished by its sizable asset base and relatively low net expense ratio among peers, supporting its competitiveness in the Muni National Intermediate category. Its role in the financial market is to serve individual and institutional investors seeking tax-advantaged income while mitigating risk through diversification and professional management.
