Strategy Narrative [Text Block]	The Fund will invest primarily in common stocks of companies across all market capitalizations. The Fund may at any given time invest a significant portion of its assets in companies of one particular market capitalization category, such as large capitalization companies.Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of growth companies.Growth companies are those that the adviser believes have strong growth potential compared to companies in the U.S. market more broadly, based on one or more of the following factors: projected future revenue growth, projected future earnings growth, historical revenue growth or historical earnings growth. “Assets” means net assets plus the amount of borrowings for investment purposes. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. To the extent the Fund uses derivatives, the Fund will primarily use futures contracts to more effectively gain targeted equity exposure from its cash positions. Investment Process: The Fund invests in companies that the adviser believes have strong earnings growth potential. In managing the Fund, the adviser employs a process that combines research, valuation and stock selection to identify companies that have a history of above-average growth or which the adviser believes will achieve above-average growth in the future. Growth companies purchased for the Fund include those with leading competitive positions that can achieve sustainable growth. As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in issuers and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive, and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors. The Fund is non-diversified and may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. The adviser may sell a security for several reasons. A security may be sold due to a change in the company’s fundamentals or if the adviser believes the security is no longer attractively valued. Investments may also be sold if the adviser identifies a stock that it believes offers a better investment opportunity.
