It assumes that you invest $10,000 in the Fund for the time periods indicated, that your investment has a 5% return each year, that the Fund’s operating expenses remain the same, and that you redeem all of your shares at the end of those periods. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years	5 Years	10 Years
$104	$323	$560	$1,241

PORTFOLIO TURNOVER

The Fund pays transactions 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 15.93% of the average value of the portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund seeks to achieve its objective by investing, under normal market conditions, at least 80% of its net assets in the common stocks of companies with capitalizations of $5 billion or more at the time of purchase.

The Adviser invests in domestic growth-oriented companies it believes exhibit the potential for superior growth. The Fund focuses on stocks issued by companies with long records of earnings and revenue growth. The Adviser believes that a company’s earnings growth is the primary determinant of its potential long-term return and evaluates a company’s potential for above average long-term earnings and revenue growth. Several factors are considered in the Adviser’s evaluation of a company, including:

>	unique product or service,
>	growing product demand,
>	dominant and growing market share,
>	management experience and capabilities, and
>	strong financial condition.

When selling equity securities for the Fund, the Adviser considers several factors, including changes in a company’s fundamentals and anticipated earnings.
