Strategy. The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its assets in micro capitalization companies.

As of August 31, 2025, the market capitalization range of the companies in the Bloomberg US Micro Cap Total Return Index was between approximately $1,973,800 and $6.92 billion. The Fund maintains a diversified portfolio of investments consisting primarily of common stocks.

As of August 31, 2025, the market capitalization range of the companies in the Bloomberg US Micro Cap Total Return Index was between approximately $1,973,800 and $6.92 billion. The Fund maintains a diversified portfolio of investments consisting primarily of common stocks. The Fund may also invest in other equity securities, such as preferred stocks, rights, or warrants. The Adviser expects to select investments for the Fund in companies across various industry groups. The Adviser manages the Funds portfolio in an aggressive growth style. The Adviser believes that investments in micro capitalization companies can have greater earnings and sales growth potential than larger capitalized companies and can offer substantial opportunities for long-term growth of capital. The Advisers overall stock selections are based on its qualitative and quantitative assessment of a companys fundamental prospects and whether it has an above-average potential for long-term growth of capital. The Adviser expects to invest the Funds net assets primarily in U.S. companies, but may gain exposure to foreign markets, including emerging markets, through the global operations of U.S. companies, by purchasing depositary receipts or securities of foreign companies traded on U.S. exchanges, or through direct investment in foreign companies. The Adviser will not invest more than 25% of the Funds net assets directly in foreign companies. The Fund may have significant exposure to the health care sector. The Fund intends to hold some cash, short-term debt obligations, government securities or other high-quality investments for reserves to cover redemptions and unanticipated expenses, or to maintain liquidity while seeking appropriate investments. The Fund may lend its portfolio securities to seek to generate additional income.
