Analysis · MFM · Unknown
This prospectus supplement details a material change in the investment policy for MFS Municipal Income Trust, effective June 1, 2026. The fund will now be authorized to invest up to 100% of its assets in municipal obligations rated below investment grade, a substantial increase from the prior 20% limit. This shift significantly elevates the fund's risk profile, as below-investment grade bonds carry higher credit risk in exchange for potentially higher yields.
