The Advisor invests in small capitalization companies with market capitalizations below that of the largest member of the Russell 2000 Index at the time of purchase. As of April 30, 2022, the capitalization of the largest member of the Russell 2000 Index was $15.1 billion. The Fund typically invests in 30 to 50 companies. Under normal circumstances, the Fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in U.S. common stocks of small capitalization companies, as defined above. The Fund emphasizes a "value" investment style, investing in companies that appear underpriced according to certain financial measurements of their worth or business prospects. Financial measures which are used to assess value are Price to Book ratio and Enterprise Value to EBITDA (Earnings before interest, taxes, depreciation and amortization) ratio and other widely used valuation metrics. Those ratios are compared to similar metrics for the market and comparable securities. The Advisor defines Enterprise Value as the market value of a company's equity, debt and unfunded pension claims, less cash. EBITDA is a company's earnings before interest, taxes, depreciation and amortization. The Advisor may sell a company when the company reaches the Advisor's projection of the stock's future target price, as determined by applying the Advisor's understanding of historical valuation metrics, when there is a more attractively priced company as an alternative, when the fundamentals of the business have changed, or when the Advisor determines that management of the company is not enhancing shareholder value. These portfolio reviews are conducted continuously through close monitoring of stock prices, changes in the economy, and corporate developments. Show less
