About MBMSX

MFS Mississippi Municipal Bond Fund Class B is a mutual fund specializing in municipal bonds, with a particular focus on debt securities from issuers located in Mississippi. The fund’s core purpose is to provide investors with current income that is exempt from federal and Mississippi personal income taxes. By investing primarily in tax-exempt bonds, the fund appeals to individuals seeking tax-advantaged income streams. Managed within the “Muni Single State Long” category, it allocates no more than one third of its assets to securities rated below the top three investment grades, prioritizing quality and risk management. The fund holds a diversified portfolio of municipal issues, often including bonds supporting infrastructure, healthcare, and public development projects within Mississippi, and occasionally other states for diversification. Regular monthly dividend distributions are a notable feature, reinforcing its income focus. Since its inception in 1993, the fund has provided investors with access to tax-exempt municipal debt markets and played a role in facilitating essential public financing. Its performance is measured against the Bloomberg Municipal Bond Index, and it is notable for its contingent deferred sales charge structure, which declines over time.
