About MPMNX

MFS Municipal Income Fund R6 is a mutual fund focused on providing investors with total return—combining income and capital appreciation—with an emphasis on generating income exempt from federal income tax. The fund primarily invests at least 80% of its net assets in municipal bonds and related instruments, the interest from which is generally free from federal income tax, though some interest may be subject to the federal alternative minimum tax. Managed by Massachusetts Financial Services, the asset portfolio is diversified across various municipal sectors, commonly including issues related to education, healthcare, housing, utilities, and infrastructure. The fund employs an active management approach, blending fundamental municipal credit analysis with quantitative tools and risk management techniques. This results in a diversified portfolio that typically maintains a medium credit quality exposure and extensive interest rate sensitivity. Notably, the fund's strategy may involve derivatives to manage risk or enhance yield, and its assets are drawn from a broad mix of issuers across different states and territories. MFS Municipal Income Fund R6 is designed for investors seeking federally tax-exempt income, benefiting from the asset manager's deep sector experience and disciplined investment process.
