The objective of income is secondary. Fees and Expenses This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) 0.0065 0.0065 0.0025 0.0000 0.0099 0.0099 0.0189 0.0164 The Total Fund Operating Expenses differ from the Ratio of gross expenses to average net assets found within the "Financial Highlights" section of the prospectus because Other Expenses have been restated to reflect current fees. Example This example is intended to help you compare the cost of investing in shares of the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in shares of the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 192 594 1021 2212 167 517 892 1944 Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 13% of the average value of its portfolio. 0.13 Principal Investment Strategies The Fund invests in equity securities of U.S.-based companies whose growth, cash flow, earnings and dividend prospects are promising and whose securities are reasonably priced and have the potential for capital appreciation in the opinion of portfolio management. Portfolio management looks for companies with strong balance sheets, attractive return on capital and sustainable earnings growth. In evaluating the prospects for a company’s growth and earnings, portfolio management considers, among other things, the company’s historical performance and growth strategy, the growth rate of the industries in which it operates and the markets into which it sells, the nature of its competitive environment, technological developments, and trends in market share. Portfolio management uses models that quantify and rank stocks based on their underlying financial data and blend this analysis with fundamental, bottom-up analysis from one or more investment analysts. This blending of quantitative and fundamental analysis allows portfolio management to efficiently evaluate a large number of potential investments in a systematic fashion while retaining the insights of investment analysts to provide investment considerations which may not be observable from a company’s financial information. The equity securities in which the Fund invests consist primarily of common stocks of large-capitalization companies, including a mix of dividend-paying companies and those offering strong growth potential. The Fund considers large-capitalization companies to be those with market capitalizations in excess of $10 billion or in the range of those market capitalizations of companies included in the S&P 500 Index at the time of purchase. The capitalization range of the companies that are components of the S&P 500 Index was between $5.7 billion and $5.5 trillion as of September 30, 2026. The average market cap of index components was $136 billion. It is the Fund’s policy to invest, under normal circumstances, at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in the equity securities of large-capitalization companies. Although the Fund can invest in stocks of any sector, the Fund, subject to its investment policies, may at times have significant investments in one or more sectors. The equity securities in which the Fund may invest also include common stocks that do not pay dividends, particularly when portfolio management believes they offer strong potential for capital appreciation. It is the Fund’s policy to invest, under normal circumstances, at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in the equity securities of large-capitalization companies. It is possible to lose money by investing in the Fund. An investment in the Fund is not a deposit or obligation of any bank, is not insured or guaranteed by any bank, and is not insured by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. <table cellpadding="0" cellspacing="0" style="font: 11pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 20%; text-align: justify">Company Risk</td> <td style="width: 80%; text-align: justify">The market values of corporate securities vary with the success or failure of the company issuing the stock. Many factors can negatively affect a particular company’s stock price, such as poor earnings reports, loss of major customers, major litigation against the company or changes in government regulations affecting the company or its industry.

Portfolio management will apply investment techniques, experience, and risk analyses in making investment decisions for the Fund. However, there is no guarantee that the techniques and analyses applied by portfolio management will achieve the investment objectives. The Fund’s strategy relies heavily on quantitative models to construct the Fund’s portfolio. Relying on quantitative models entails the risk that the models themselves may be limited or incorrect, that the data on which the models rely may be incorrect or incomplete, and that portfolio management may not be successful in selecting companies for investment or determining the weighting of particular stocks in the Fund’s portfolio. Any of these factors could cause the Fund to underperform funds with similar strategies that do not select stocks based on quantitative analysis.</td></tr> </table> <table cellpadding="0" cellspacing="0" style="font: 11pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="text-align: justify; width: 20%">Market Risk</td> <td style="text-align: justify; width: 80%">The value of the securities owned by the Fund can increase and decrease quickly at unexpected times. The value can change as the result of a number of factors, including the economic outlook, geopolitical risks, market-wide risks, industry-specific risk (i.e., labor shortages and/or stoppages, greater costs of production and/or competitive forces or conditions) or issuer-specific risk.

Market disruptions could cause the Fund to lose money, experience significant redemptions, and encounter operational difficulties. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market.
