Fund Description

MFS (Massachusetts Financial Services Company, the fund’s investment adviser) normally invests at least 80% of the fund’s net assets in inflation-adjusted debt instruments and other instruments with similar economic characteristics. Inflation-adjusted debt instruments are debt instruments whose principal and/or interest payments are adjusted for realized inflation.

MFS generally focuses the fund’s investments in inflation-adjusted debt instruments issued by the U.S. Treasury. MFS may also invest the fund’s assets in other inflation-adjusted debt instruments and non-inflation-adjusted debt instruments, including corporate debt instruments, foreign government securities, securitized instruments, and other debt instruments.

MFS generally invests substantially all of the fund’s assets in investment grade quality debt instruments.

MFS may invest a significant percentage of the fund’s assets in a single issuer or a small number of issuers.

MFS may invest the fund’s assets in foreign securities.

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 or currency exposure, or as alternatives to direct investments. Derivatives include futures, forward contracts, options, and swaps.

MFS uses an active investment approach in managing the fund that combines top-down considerations and bottom-up fundamental investment analysis to make decisions about sector allocations, duration and yield curve positioning, and security selection. In addition, market technicals (e.g., bond supply/demand dynamics) are typically considered in determining sector allocations and specific security selection. Quantitative screening tools may also be considered in determining the fund’s portfolio positioning.

For purposes of the fund's 80% policy, net assets include the amount of any borrowings for investment purposes.
