About MMIGX
MFS Municipal Income Fund Class B1 is a long-duration, actively managed mutual fund focused on generating total return, with an emphasis on income that is exempt from federal income tax. The fund predominantly invests in a diversified portfolio of municipal bonds issued by various U.S. state and local governments to finance public projects, such as infrastructure, schools, and utilities. Its strategy favors investment-grade securities but may also allocate a portion to bonds of lower credit quality, balancing risk and potential returns. Class B1 shares are available to holders who acquired them through a legacy fund acquisition process. As of mid-2025, the fund holds over $5.8 billion in net assets, with municipal holdings comprising the vast majority of its portfolio. The fund employs a risk-aware management approach utilizing both quantitative market tools and experienced analysts to identify and mitigate risks. Income is distributed monthly, and the fund is benchmarked to the Bloomberg Municipal Bond Index, reflecting its alignment with the broader national municipal bond market. MFS brings decades of municipal bond investing experience and seeks to provide consistent, tax-advantaged income for investors.
