Shareholder Fees (fees paid directly from your investment) 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 you redeem all of your shares at the end of those periods.

If these sales charges (loads) were included, your costs would be higher. 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 may indicate higher transaction costs. 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 __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

The Fund should place these additional captions directly below the "Total Annual Fund Operating Expenses" caption of the table and should use appropriate descriptive captions, such as "Fee Waiver [and/or Expense Reimbursement]" and "Total Annual Fund Operating Expenses After Fee Waiver [and/or Expense Reimbursement]," respectively.

An investment in the Fund is not a deposit in any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fluctuate significantly, which means loss of money is a risk of the Fund. In addition, the Fund is subject to the following risks: General Market Risk: Factors affecting the securities markets include domestic and foreign economic growth and decline, interest rate levels, and political events. There is a risk the investment adviser will not accurately predict the direction of these and other factors and, as a result, the investment adviser's investment decisions may not accomplish what they were intended to achieve. Common Stock Risk: Companies in which the Fund is invested may not perform as anticipated. Additionally, the value of a Fund investment may increase or decrease more than the stock market in general. A downturn in the stock market may lead to lower market price for a stock even when the company's fundamentals are strong. A company's stock may drop as a result of technological, environmental, or regulatory change or as a result of company news or a change in expected earnings. Large-Cap Stock Risk: Large-cap companies may be unable to respond quickly to new competitive challenges like changes in technology or consumer taste, and also may not be able to attain the high growth rates of successful, smaller companies, especially during periods of economic expansion. Mid-Cap Stock Risk: Mid-cap stocks are generally less liquid than large-cap stocks, and may be more affected by technological, environmental, or regulatory change. Foreign Investment Risk: Investing in foreign securities can involve more risks than in U.S. domestic investments because of political, social, and economic developments abroad. Other risks result from differences between regulations that apply to U.S. and foreign issuers and markets, and the potential for foreign markets to be less liquid and more volatile than U.S. markets. Convertible Securities Risk: The Fund may purchase convertible securities which may be converted at a stated price within a specified period of time into a certain quantity of common stock of the same or other issuers. When interest rates rise, the values generally fall, and when rates decline, the values generally increase. In addition, their prices can be affected by changes in the market value of the common stock into which they can be converted. Growth Investing Risk: The Fund's growth approach to its equity investing could cause it to underperform other funds that employ a different investment style, depending on market conditions and investor sentiment. There is also a risk that the stocks selected for this Fund may not grow as the investment adviser anticipated. falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.
