Although expected to change frequently, the market capitalization range of the Index was approximately $681 million to $3.3 trillion as of March 31, 2025. The Fund is classified as "non-diversified" under the Investment Company Act of 1940 (the "1940 Act"). The Fund invests primarily in the common stock of growth-oriented companies. The Fund may from time to time emphasize one or more sectors in selecting its investments, such as the information technology sector. The Fund may invest up to 20% of its total assets in foreign securities (not including American Depositary Receipts, American Depositary Shares or U.S. dollar denominated securities of foreign issuers). The Subadviser employs a "bottom-up" approach, using fundamental analysis to identify specific securities within industries or sectors for purchase or sale. A "bottom-up" approach evaluates individual companies in the context of broader market factors. Fund construction emphasizes stock-specific risk while seeking to minimize other sources of broad market risk. The goal is a portfolio whose relative performance is not dependent on the market environment. The Subadviser's stock selection process is derived from its observation that the quality and persistence of a company's business is often not reflected in its current stock price. Central to the investment process is fundamental research focused on uncovering companies with improving quality metrics, business momentum, and attractive relative valuations. The investment process is aided by a proprietary screening process that narrows the investment universe to companies that are consistent with the Subadviser's investment philosophy. The Subadviser typically may sell investments when it believes that they no longer offer attractive future returns compared with other investment opportunities or that they present undesirable risks or in an attempt to limit losses on investments that may decline or have declined in value.
