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 in the example, affect the Funds performance. During the most recent fiscal year, the Funds portfolio turnover rate was 21.94% of the average value of the portfolio. Principal Investment Strategies To pursue the Funds investment objective of long-term growth, it primarily invests in common stocks of domestic small, medium- and large-sized companies believed to have growth potential. The Fund believes a companys annual sales volume and market capitalization (the number of shares outstanding multiplied by the per share price) are the factors most illustrative of a companys size. In distinguishing company size in terms of sales volume, the Fund considers a companys sales volume relative to peer companies in the companys industry. In terms of market capitalization, the Fund generally considers companies with market capitalizations up to $2 billion as small, between $2 billion and $10 billion as medium and greater than $10 billion as large. The Fund looks for established companies with the potential for superior growth in sales and earnings in a diversified group of industries. The Funds investment philosophy is basically a long-term growth philosophy, based upon the assumption that if a company achieves superior growth in sales and earnings, eventually the companys stock will achieve superior performance. It is anticipated that a major portion of the Funds portfolio will be invested in common stocks of the types of companies, and in the manner, as described above. Principal Risks of Investing As with any mutual fund, the Fund cannot guarantee that it will achieve its goals or that its performance will be positive over any period of time. The Funds investments change in value. Consequently, the value of your Fund shares may change. If the value of the Fund shares or the values of the Funds investments go down, you may lose money. The principal risks of investing in the Fund are: Market Risk Market risk involves the possibility that the value of the Funds investments will fluctuate as the stock market fluctuates over short- or longer-term periods. Common stock prices tend to be more volatile than other investment choices.
Portfolio-Specific Risk From time to time, the value of an individual company may decline due to a particular set of circumstances affecting that company, its industry or certain companies within the industry, while having little or no impact on other similar companies within the industry. Although the Fund will invest most of its assets in the securities of medium- and large- sized companies, the Fund may face additional risks due to its investments in small-sized companies. Securities of small- to medium-sized companies often fluctuate in price more than common stocks of larger companies.
Selection Risk The Fund also faces selection risk, which is the risk that the stocks the Fund purchases will underperform markets or other mutual funds with similar investment objectives and strategies. Since there are risks inherent in all investments in securities, there is no assurance that the Funds objective will be achieved. 2
