The fund invests at least 80% of its net assets plus any borrowings for investment purposes (measured at the time of purchase) ("net assets") in equity investments in small-, mid- and large-cap issuers. Although the fund invests primarily in publicly traded U.S. securities, it may invest up to 25% of its net assets in foreign securities, including securities of issuers in countries with emerging markets or economies ("emerging countries") and securities quoted in foreign currencies.
