MFS High Yield Municipal Trust is a diversified, closed-end management investment company. The fund's primary investment objective is to seek high current income that is exempt from federal income taxes. Capital appreciation is a secondary objective. To achieve its goals, the fund invests primarily in a portfolio of high-yield municipal bonds and tax-exempt notes. The trust operates under a managed distribution plan, where distributions may consist of investment income, long-term capital gains, or a return of capital if sufficient investment income is not available on a monthly basis.
