MFS may invest the funds assets in securities of companies of any size. MFS normally invests the fund's assets across different industries, sectors, countries, and regions, but MFS may invest a significant percentage of the funds assets in issuers in a single industry, sector, country, or region. MFS may invest a significant percentage of the funds assets in a single issuer or a small number of issuers. 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. Quantitative screening tools that systematically evaluate issuers may also be considered. For purposes of the fund's 80% policy, net assets include the amount of any borrowings for investment purposes. Show less
