*  A contingent deferred sales charge of 1.00% applies on certain redemptions made within 18 months following purchases of $1 million or more made without an initial sales charge. Contingent deferred sales charge is calculated based on the lesser of the offering price and market value of shares being sold.

Example

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem or hold 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. You may be required to pay brokerage commissions on your purchases and sales of Class F-2, F-3, 529-F-2 or 529-F-3 shares of the fund, which are not reflected in the example.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 investment results. During the most recent fiscal year, the fund’s portfolio turnover rate was 32% of the average value of its portfolio.

Principal investment strategies

The fund invests primarily in common stocks of established companies that are listed on, or meet the financial listing requirements of, the New York Stock Exchange and have a strong record of earnings and dividends. The fund strives to accomplish its objective through fundamental research, careful selection and broad diversification. In the selection of common stocks and other securities for investment, current and potential income as well as the potential for long-term capital appreciation are considered. The fund seeks to provide an above-average yield in its quarterly income distribution in relation to the S&P 500 Index (a broad, unmanaged index). The fund strives to maintain a fully invested, diversified portfolio, consisting primarily of high-quality common stocks.

The fund has Investment Standards originally based upon criteria established by the United States District Court for the District of Columbia for determining eligibility under the Court’s Legal List procedure, which was in effect for many years. The fund has an “Eligible List” — based on the Investment Standards — of securities considered appropriate for a prudent investor seeking opportunities for income and growth of principal consistent with common stock investing. The investment adviser generates and maintains the Eligible List in compliance with the fund’s Investment Standards and selects the fund’s investments exclusively from the securities on the Eligible List.

The investment adviser uses a system of multiple portfolio managers in managing the fund’s assets. Under this approach, the portfolio of the fund is divided into segments managed by individual managers.

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.

After-tax returns are shown only for Class F-2 shares; after-tax returns for other share classes will vary. After-tax returns are calculated using the highest individual federal income tax rates in effect during each year of the periods shown and do not reflect the impact of state and local taxes. Your actual after-tax returns depend on your individual tax situation and likely will differ from the results shown above. In addition, after-tax returns are not relevant if you hold your fund shares through a tax-favored arrangement, such as a 401(k) plan, individual retirement account (IRA) or 529 college savings plan.
