A team of investment research analysts selects investments for the fund. MFS generally expects the fund's exposure to broad industry categories to approximate the exposure of the Russell 3000 Index to these broad industry categories using MFS' custom industry categories to classify the fund and the Russell 3000 Index's holdings. 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.
