About MTLBX

MFS Municipal Limited Maturity Fund Class B is an open‑end municipal bond mutual fund focused on generating total return with an emphasis on income that is exempt from federal income tax, while maintaining capital preservation as a priority. The portfolio invests primarily in U.S. municipal securities and normally keeps a dollar‑weighted average effective maturity not exceeding five years, placing it within the muni national short category that targets bonds supporting state and local public projects. The fund employs a risk‑aware, portfolio‑management‑driven approach that leverages quantitative tools to monitor market risk and a seasoned analyst team to assess issuer‑specific risk. It distributes income on a monthly basis and has a long operating history dating back to the early 1990s under the MFS fund family. The strategy emphasizes diversified exposure across municipal sectors and geographies, seeking consistent long‑term results relative to the Bloomberg 1–9 Year Municipal Bond Index, the fund’s stated benchmark. While dividends are generally federally tax‑exempt, a portion may be subject to the alternative minimum tax, and state and local tax treatment varies.
