Equity securities include common stocks, depositary receipts, and other securities that represent an ownership interest (or right to acquire an ownership interest) in a company or other issuer. Debt instruments include corporate bonds, U.S. Government securities, securitized instruments (including mortgage-backed securities and other asset-backed securities), and other obligations to repay money borrowed. MFS generally invests approximately 60% of the funds assets in equity securities and approximately 40% of the fund's assets in debt instruments. These weightings do not reflect the fund's cash balance and can vary over time due to market movements and cash flows. Of the fund's investments in equity securities, MFS focuses on investing the fund's assets in the stocks of companies it believes are undervalued compared to their perceived worth (value companies). MFS normally invests a portion of the funds assets in income-producing equity securities. While MFS may invest the equity portion of the funds assets in securities of companies of any size, MFS primarily invests in securities of companies with large capitalizations. Of the funds investments in debt instruments, MFS generally invests substantially all of these investments in investment grade quality debt instruments. MFS may purchase or sell securities for the fund on a when-issued, delayed delivery, or forward commitment basis where payment and delivery take place at a future settlement date, including mortgage-backed securities purchased or sold in the to be announced (TBA) market. 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 issuers and instruments. Quantitative screening tools that systematically evaluate issuers and instruments may also be considered. Show less
