Strategy [Heading]	<span style="color:#000000;font-family:Arial Narrow;font-size:11pt;font-weight:bold;">What are the Fund’s main investment strategies?</span>
Strategy Narrative [Text Block]	Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of U.S. companies.Equity securities represent an ownership interest in the issuer. In implementing its strategy, the Fund invests primarily in common stocks of large- and medium-capitalization U.S. companies but it may also invest up to 20% of its Assets in common stocks of foreign companies, including depositary receipts. Depositary receipts are financial instruments representing a foreign company’s publicly traded securities. A depositary receipt trades on a stock exchange in a country different from the company’s local market. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund focuses on those equity securities that it considers attractively valued and seeks to outperform the Benchmark through superior stock selection. By emphasizing attractively valued equity securities, the Fund seeks to produce returns that exceed those of the Benchmark. Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for investments in certain securities. The Fund may use derivatives, primarily futures contracts, to gain exposure to its index or certain securities in its index, or to more effectively gain targeted equity exposure from its cash positions. To the extent the Fund invests in index futures with exposure to securities in the index, it may have the effect of increasing the Fund’s exposure to a relatively small number of securities, making the Fund’s shares more sensitive to the economic results of those securities. An issuer of a security will be deemed to be located in the United States if: (i) the principal trading market for the security is in the United States, (ii) the issuer is organized under the laws of the United States, or (iii) the issuer derives at least 50% of its revenues or profits from the United States or has at least 50% of its total assets situated in the United States.Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and stock selection. The adviser takes an in-depth look at company prospects, which is designed to provide insight into a company’s real growth potential. The research findings allow the adviser to rank the companies in each sector group according to their relative value. 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. On behalf of the Fund, the adviser then buys and sells equity securities, using the research and valuation rankings as a basis. In general, the adviser buys equity securities that are identified as attractively valued and considers selling them when they appear to be overvalued. Along with attractive valuation, the adviser often considers a number of other criteria: ●catalysts that could trigger a rise in a stock’s price ●high potential reward compared to potential risk ●temporary mispricings caused by apparent market over-reactions.
