Under normal market conditions, the fund invests at least 80% of its net assets in common stocks and other equity-type securities (including preferred stock, convertible securities and hybrid securities) of large, growth companies in the United States. The investment adviser currently defines “large companies” to be companies whose market capitalizations typically fall within the range of the Russell 1000 Index. As of July 1, 2025, the smallest company for the Russell 1000 Index had a market capitalization of approximately $823.2 million and the largest company for the Russell 1000 Index had a market capitalization of approximately $3.8 trillion. The market capitalization of the companies included in the Russell 1000 Index will change with market conditions. The investment adviser currently defines “growth companies” to be companies that are included in the Russell 1000 Growth Index or exhibit the potential for growth based on historical or projected revenue or earnings, or if the investment adviser expects the company to contribute to the fund’s long-term growth of capital based on factors such as whether the company is attractively valued or is positioned to benefit from innovation, economic growth, or increasing consumer demand. The fund strives to maintain a fully invested portfolio.

The fund is nondiversified, which means it may invest a greater portion of its assets in fewer issuers than would otherwise be the case.

The investment adviser uses a system of multiple portfolio managers in managing assets. Under this approach, a portfolio is divided into segments managed by individual managers. For more information regarding the investment process of the fund, see the “Management and organization” section of this prospectus.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund’s portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively valued companies that, in its opinion, represent good, long-term investment opportunities. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.
