About MFIAX

MFS Municipal Income Fund Class A is a mutual fund designed to deliver a total return with a primary focus on generating income that is exempt from federal income tax, while also considering opportunities for capital appreciation. This fund predominantly invests in high-quality municipal bonds, allocating over 98% of its portfolio to municipal securities, with a minimal percentage in high yield and investment-grade corporate bonds as well as cash equivalents. Managed by a seasoned investment team, the fund utilizes a disciplined risk-budgeting approach and integrates both quantitative tools and fundamental credit research to identify and manage risks. Since its inception in 1986, it has aimed to provide stable, tax-advantaged income suitable for investors with long-term goals and varying risk tolerances. The fund tracks its performance against the Bloomberg Municipal Bond Index, acting as a benchmark for the broader municipal bond market. With substantial net assets, it plays a prominent role in the fixed income market, particularly for investors seeking federally tax-exempt income through a diversified municipal bond portfolio.
