The Fund invests principally in common stocks and other equity securities of U.S. small- and mid- (smid) capitalization companies. Under normal circumstances, the Fund invests at least 80 percent of its net assets, plus borrowings for investment purposes, in securities of smid-cap companies, which the Fund defines as those with market capitalizations that fall within the range of the Russell 2500 Index (the Index) provided that the upper end of the capitalization range of that Index equals or exceeds dollar 12 billion. If the upper end of the Indexs capitalization range falls below 12 billion dollars, the Fund will continue to define those companies with market capitalizations between the lower end of the range of the Index and dollar 12 billion as smid-cap companies. As of December 31, 2024, the range of the Index was dollar 6 million to dollar 33.0 billion, but it is expected to change frequently.
