Effective immediately, the like paragraph describing MFS' approach to buying and selling investments in the sub-section entitled "Principal Investment Strategies" under the main heading entitled "Investment Objective, Strategies, and Risks" is restated in its entirety as follows:

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/or instruments in light of the issuer's financial condition and market, economic, political, and regulatory conditions. Factors considered for equity securities may include analysis of an issuer's earnings, cash flows, competitive position, and management ability. Factors considered for debt instruments may include the instrument’s credit quality, collateral characteristics, and indenture provisions, and the issuer’s management ability, capital structure, leverage, and ability to meet its current obligations. MFS may also consider environmental, social, and governance (ESG) factors in its fundamental investment analysis. Quantitative screening tools that systematically evaluate the valuation, price and earnings momentum, earnings quality, and other factors of the issuer of an equity security or the structure of a debt instrument may also be considered.
