The MFS Multimarket Income Trust operates as a closed-end investment vehicle, exclusively focusing on fixed-income securities. Managed by MFS Investment Management, Inc., its investment strategy encompasses global debt markets, with a significant allocation directed towards the United States. The fund diversifies its holdings across various debt instruments, including government bonds from both U.S. and international entities, mortgage-backed securities (MBS) and other asset-backed securities (ABS) from domestic and foreign issuers, corporate bonds issued by U.S. and overseas companies, and sovereign or corporate debt originating from emerging market countries. The portfolio is structured with an average duration of 5.1 years. Investment decisions are underpinned by thorough fundamental analysis and a bottom-up security selection process, scrutinizing aspects like intrinsic credit quality, collateral characteristics, indenture provisions, the issuer's management capabilities, capital structure, leverage ratios, and its ability to meet ongoing obligations. Performance is gauged against a blended benchmark consisting of the Citigroup World Government Bond Non-Dollar Hedged Index, JPMorgan Emerging Markets Bond Index Global, Lehman Brothers U.S. Credit Bond Index, Lehman Brothers U.S. Government/Mortgage Bond Index, and Lehman Brothers U.S. High-Yield Corporate Bond Index. The Trust was established in the United States on March 12, 1987.
