About NSMMX

Columbia Short Duration Municipal Bond Fund Class A is an actively managed mutual fund specializing in short-term U.S. municipal bonds. Its primary purpose is to provide high current income exempt from federal income tax while maintaining minimal fluctuation of principal. The fund typically invests at least 80% of its net assets in securities that pay interest exempt from federal income tax, targeting a portfolio with a dollar-weighted average maturity of less than three years. This short-duration focus is designed to reduce interest rate risk relative to longer-term municipal bond funds. Managed by Columbia Threadneedle, the fund holds a diverse range of municipal debt instruments issued by state and local governments to support public projects, thereby offering exposure to the infrastructure and public funding sector. Monthly dividend payouts are a notable feature, with a current yield aimed at delivering steady, tax-advantaged income. With hundreds of holdings and a long-established track record since 1993, the fund serves as a tool for investors seeking capital preservation and stable income in the fixed income market, particularly those prioritizing tax efficiency.
