EAHIX Investment Objective and Strategy
MFS High Income Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Mfs Series Trust III.
Investment objective
The funds investment objective is to seek total return with an emphasis on high current income, but also considering capital appreciation.
Principal investment strategy
"MFS (Massachusetts Financial Services Company, the funds investment adviser) normally invests at least 80% of the funds net assets in high income debt instruments. Debt instruments include corporate debt instruments, foreign government securities, floating rate loans, and other obligations to repay money borrowed. High income debt instruments are debt instruments that are below investment grade quality. Below investment grade quality debt instruments are debt instruments rated BB+ or lower by S&P or Fitch, or Ba1 or lower by Moodys, or comparably rated by another Nationally Recognized Statistical Rating Organization (""NRSRO""). MFS may invest the funds assets in other types of debt instruments. MFS may invest up to 100% of the funds assets in below investment grade quality debt instruments.
MFS may invest the funds assets in foreign securities. MFS normally invests the fund's assets across different industries and sectors, but MFS may invest a significant percentage of the fund's assets in issuers in a single industry or sector. While MFS may use derivatives for any investment purpose, to the extent MFS uses derivatives, MFS expects to use derivatives primarily to increase or decrease exposure to a particular market, segment of the market, or security, to increase or decrease interest rate exposure, or as alternatives to direct investments. Derivatives include futures, forward contracts, options, and swaps. MFS uses an active bottom-up investment approach to buying and selling investments for the fund. Investments are selected primarily based on fundamental analysis of individual instruments and their issuers.
Quantitative screening tools that systematically evaluate instruments may also be considered. In structuring the fund, MFS also considers top-down factors. For purposes of the fund's 80% policy, net assets include the amount of any borrowings for investment purposes."
