The Fund invests primarily in common stocks. The Fund, under normal circumstances, will invest at least 80% of its assets in securities issued by U.S. companies (80% policy). The Fund generally invests in companies included in the Russell 1000 Growth Index (Index), which represents the large cap growth segment of the U.S. equity universe. As of March 31, 2025, the Index included 389 companies. The Fund invests in companies that the Sub-Adviser believes have long-term capital appreciation potential and are expected to grow faster than the U.S. economy. Using a systematic bottom-up approach, the Sub-Adviser seeks to select securities they believe have solid earnings appreciation coupled with a demonstrated business quality, as seen thought superior profitability, balance sheet strength, earnings stability and corporate sustainability. Stocks also need to have reasonable company valuations relative to their current growth prospects, and their peer group. All of these factors give the Sub-Adviser insight into the outlook for a company, helping the Sub-Adviser identify companies poised for sustainable growth. The Sub-Adviser believes that sustainable growth, if it occurs, may result in price appreciation for the companys stock. Because the Fund generally invests in companies included in the Index, it may have a significant portion of its investments in the information technology sector. The Sub-Adviser may sell a security if they no longer believe that the security is likely to contribute to meeting the investment objective of the Fund or if there are other opportunities that appear more attractive. The Fund is non-diversified for purposes of the Investment Company Act of 1940, and as a result may invest a greater percentage of assets in a particular issuer than a diversified fund. The Funds 80% policy is nonfundamental and may be changed without shareholder approval. Fund shareholders would be given at least 60 days notice prior to any such change. Show less
