MFS Multimarket Income Trust (NYSE: MMT) is a diversified, closed-end management investment company that seeks high current income with a secondary objective of capital appreciation. The fund normally invests at least 80% of its net assets in fixed-income securities, including high-yield corporate bonds, investment-grade corporate bonds, emerging markets debt, U.S. Treasuries, collateralized loan obligations, commercial and residential mortgage-backed securities, asset-backed securities, municipals, and debt instruments issued by U.S. and foreign governments, with an average effective duration of approximately 5 years and up to 100% exposure to below-investment-grade debt; it employs leverage, derivatives for both long and short positions, and a managed distribution plan targeting an 8.00% annual rate paid monthly, which may include return of capital. Managed by MFS Investment Management since its inception on March 12, 1987, the fund is headquartered at 111 Huntington Avenue, Boston, Massachusetts, and provides global exposure across developed and emerging markets to institutional and retail income-focused investors.
In December 2025, the Board of Trustees approved proposed reorganizations whereby MFS Charter Income Trust (MCR), MFS Government Markets Income Trust (MGF), MFS Intermediate High Income Fund (CIF), and MFS Intermediate Income Trust (MIN) would merge into MMT as the surviving fund, subject to shareholder approval at a special meeting scheduled for March 11, 2026; concurrent proposals include appointing Aberdeen Investments as the new investment adviser, adding five new trustees, issuing additional common shares, and potentially renaming the fund to Aberdeen Multi-Market Income Fund upon closing.
