Example. The following 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 a class of shares of the Fund for the time periods indicated. 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 expenses would be as follows:

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 the 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 37% of the average value of its portfolio.

Principal Investment Strategies. The Fund mainly invests in common stocks of U.S. companies that the portfolio manager believes are undervalued. Under normal circumstances, the Fund will invest at least 80% of its assets in equity securities. The Fund may invest in other equity securities, such as preferred stocks, warrants and securities convertible into common stocks. The Fund may invest in equity securities issued by companies of different capitalization ranges, but will typically focus on larger capitalization stocks. The Fund may invest in equity securities both for current income from dividends as well as for growth opportunities.

The Fund can buy securities of companies in developed and emerging market countries. The Fund has no limits on the amounts it can invest in foreign securities. However, currently it does not intend to invest more than 25% of its net assets in securities of issuers in any single foreign country or more than 5% of its net assets in companies or government issuers in emerging market countries.

In selecting investments for the Fund, the portfolio manager mainly relies on a value-oriented investing style. A security may be undervalued because the market is not aware of the issuer's intrinsic value, does not yet recognize its future potential, or the issuer may be temporarily out of favor. The Fund seeks to realize gains in the prices of those securities when other investors recognize their real or prospective worth. The Fund also looks for securities that offer higher than average dividends. The portfolio manager generally uses a fundamental approach to analyzing issuers, for example, by looking at price/earnings ratios and current balance sheet information. Currently, the portfolio manager focuses on securities that have high current income and are believed to have substantial earnings possibilities, have low price/earnings ratios relative to other securities, and that have a low price relative to the underlying value of the issuer's assets, earnings, cash flow or other factors. These criteria may vary in particular cases and may change over time. The Fund may sell securities that the portfolio manager believes no longer meet these criteria, but is not required to do so.

Principal Risks. The price of the Fund's shares can go up and down substantially. The value of the Fund's investments may change because of broad changes in the markets in which the Fund invests or because of poor investment selection, which could cause the Fund to underperform other funds with similar investment objectives. There is no assurance that the Fund will achieve its investment objective. When you redeem your shares, they may be worth more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund.

Main Risks of Investing in Stock. The value of the Fund's portfolio may be affected by changes in the stock markets. Stock markets may experience significant short-term volatility and may fall sharply at times. Different stock markets may behave differently from each other and U.S. stock markets may move in the opposite direction from one or more foreign stock markets.

The prices of individual stocks generally do not all move in the same direction at the same time and a variety of factors can affect the price of a particular company's stock. These factors may include, but are not limited to: poor earnings reports, a loss of customers, litigation against the company, general unfavorable performance of the company's sector or industry, or changes in government regulations affecting the company or its industry.

At times, the Fund may emphasize investments in a particular industry or economic or market sector. To the extent that the Fund increases its emphasis on investments in a particular industry or sector, the value of its investments may fluctuate more in response to events affecting that industry or sector, such as changes in economic conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than others.

Main Risks of Other Equity Securities. Most convertible securities are subject to the risks and price fluctuations of the underlying stock. They may be subject to the risk that the issuer will not be able to pay interest or dividends when due and their market value may change based on changes in the issuer's credit rating or the market's perception of the issuer's creditworthiness. Some convertible preferred stocks have a conversion or call feature that allows the issuer to redeem the stock before the conversion date, which could diminish the potential for capital appreciation on the investment. The fixed dividend rate of preferred stocks may cause their prices to behave more like those of debt securities. If interest rates rise, the value of preferred stock having a fixed dividend rate tends to fall. Preferred stock generally rank behind debt securities in claims for dividends and assets of the issuer in a liquidation or bankruptcy. The price of a warrant does not necessarily move parallel to the price of the underlying security and is generally more volatile than that of the underlying security. Rights are similar to warrants, but normally have a shorter duration. The market for rights or warrants may be very limited and it may be difficult to sell them promptly at an acceptable price. Rights and warrants have no voting rights, receive no dividends and have no rights with respect to the assets of the issuer.

Main Risks of Small- and Mid-Sized Companies. The stock prices of small- and mid-sized companies may be more volatile and their securities may be more difficult to sell than those of larger companies. They may not have established markets, may have fewer customers and product lines, may have unseasoned management or less management depth and may have more limited access to financial resources. Smaller companies may not pay dividends or provide capital gains for some time, if at all.

Main Risks of Value Investing. Value investing entails the risk that if the market does not recognize that the Fund's securities are undervalued, the prices of those securities might not appreciate as anticipated. A value approach could also result in fewer investments that increase rapidly during times of market gains and could cause the Fund to underperform funds that use a growth or non-value approach to investing. Value investing has gone in and out of favor during past market cycles and when value investing is out of favor or when markets are unstable, the securities of "value" companies may underperform the securities of "growth" companies.

Dividend Risk. There is no guarantee that the issuers of the stocks held by the Fund will declare dividends in the future or that, if dividends are declared, they will remain at their current levels or increase over time. High-dividend stocks may not experience high earnings growth or capital appreciation. The Fund's performance during a broad market advance could suffer because dividend paying stocks may not experience the same capital appreciation as non-dividend paying stocks.

Main Risks of Foreign Investing. Foreign securities are subject to special risks. Foreign issuers are usually not subject to the same accounting and disclosure requirements that U.S. companies are subject to, which may make it difficult for the Fund to evaluate a foreign company's operations or financial condition. A change in the value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of securities denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those securities. The value of foreign investments may be affected by exchange control regulations, foreign taxes, higher transaction and other costs, delays in the settlement of transactions, changes in economic or monetary policy in the United States or abroad, expropriation or nationalization of a company's assets, or other political and economic factors. These risks may be greater for investments in developing or emerging market countries.

Time-Zone Arbitrage. The Fund may invest in securities of foreign issuers that are traded in U.S. or foreign markets. If the Fund invests a significant amount of its assets in foreign markets, it may be exposed to "time-zone arbitrage" attempts by investors seeking to take advantage of differences in the values of foreign securities that might result from events that occur after the close of the foreign securities market on which a security is traded and before the Fund's net asset value is calculated. If such time-zone arbitrage were successful, it might dilute the interests of other shareholders. The Fund's use of "fair value pricing" to adjust certain market prices of foreign securities may help deter those activities.

Who Is the Fund Designed For? The Fund is designed primarily for investors seeking total return from capital appreciation and income over the long term. Those investors should be willing to assume the risks of short-term share price fluctuations and losses that are typical for a fund emphasizing investments in equity securities. Since the Fund's income level will fluctuate, it is not designed for investors needing an assured level of current income. The Fund is not a complete investment program. You should carefully consider your own investment goals and risk tolerance before investing in the Fund.

An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
