(the Corbyn Sub-Adviser or Sub-Adviser), believes are undervalued at the time of purchase and have the potential to provide capital appreciation, income, or a combination of both. Under normal circumstances, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in equity securities of mid-sized capitalization U.S. companies (mid cap companies) at time of purchase which, for the purposes of the Fund, are those companies with market capitalizations similar to the market capitalizations of companies listed in the Russell Midcap Index or the S&P MidCap 400 Index. The Funds equity securities investments may include common and preferred stocks of United States companies. As of March 31, 2025 , the market capitalization of companies in the Russell Midcap Index ranged from approximately $ 0.3 billion to $ 198 billion and the market capitalization of companies in the S&P MidCap 400 Index ranged from approximately $ 1.2 billion to $ 18.5 billion. The companies in which the Fund may invest are those the Corbyn Sub-Adviser believes provide an attractive risk/reward value and are undervalued relative to historical valuations, the companys peers, or the securities market in general. The Sub-Adviser utilizes a bottom-up, fundamental value investing approach. The Sub-Adviser considers several factors, including, but not limited to, a companys market position, management quality, balance sheet strength, free cash flow generation, and industry or company-specific catalysts. The Fund invests primarily in U.S.-listed companies. The Sub-Adviser may sell a security for a variety of reasons, including, but not limited to, when the Sub-Advisers analysis indicates that (1) continued investment in the security no longer represents a favorable risk-reward relationship; (2) a new security is determined to have a more attractive valuation; (3) the current business, future outlook or management of a particular companys security has deteriorated; or (4) general market conditions favor a sale.
