EXAMPLE

This example is intended to help you compare the cost of investing in the Institutional Class of the Fund with the cost of investing in other mutual funds. The example assumes that you invested $10,000 in the Institutional Class of the Fund for the time periods indicated and then redeemed all of your shares at the end of those periods. The example also assumes that your investment had a 5% return each year and that operating expenses (as a percentage of net assets) of the Fund’s Institutional Class remained the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year		3 Years		5 Years		10 Years
Core Growth Fund — Institutional Class	$	114	$	399	$	705	$	1,572

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). Higher portfolio turnover 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 performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 16% of the average value of its portfolio.

PRINCIPAL STRATEGIES

The Fund invests primarily in smaller growing companies at reasonable prices.

Under normal market conditions, we will invest at least 65% of the Fund’s net assets in the equity securities of growing companies. Equity securities include common stock, preferred stock and securities convertible into common stock, warrants and rights, and other securities with equity characteristics (which include any instrument tied to a specific security or basket of securities, such as equity-linked derivatives and notes, certain options on common stock, and exchange traded funds). These companies are usually small to mid-size with market capitalizations of less than $5 billion at the time of purchase.

The Fund may invest up to 20% of its total assets at the time of purchase in securities issued by foreign companies in developed or emerging markets. Securities issued by companies incorporated outside the United States whose securities are publicly traded in the United States are not defined as foreign companies and are not subject to this limitation.

We focus on companies that we consider to be high quality. We use a process of “bottom-up” fundamental analysis to look for individual companies that we believe are stable and have the potential to grow steadily for long periods of time. Our analysis may include studying a company’s financial statements, building proprietary financial models, visiting company facilities, and meeting with executive management, suppliers and customers.

The Fund seeks to purchase stocks at prices we believe are reasonable relative to our projection of a company’s long term earnings growth rate. The secondary objective of income is achieved when fast growing portfolio companies pay dividends, generated by cash flow, typically after achieving growth targets.

The Fund may invest a large percentage of its assets in a few sectors, including industrials, financials, consumer discretionary, information technology and health care.

PRINCIPAL RISKS

All investments carry some degree of risk that will affect the value of the Fund, its investment performance and the price of its shares. As a result, you may lose money if you invest 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 (FDIC) or any other government agency.

The Fund is subject to the following principal investment risks:

Stock Market Risk. The Fund’s investments may decline in value due to movements in the overall stock market.

Stock Selection Risk. The Fund’s investments may decline in value even when the overall stock market is not in a general decline.

Foreign Securities Risk. Foreign securities are generally more volatile and less liquid than U.S. securities. Further, foreign securities may be subject to additional risks not associated with investment in U.S. securities due to differences in the economic and political environment, the amount of available public information, the degree of market regulation, and financial reporting, accounting and auditing standards, and, in the case of foreign currency-denominated securities, fluctuations in currency exchange rates.

Emerging Markets Risk. In addition to the risks of investing in foreign securities in general, the risks of investing in the securities of companies domiciled in emerging market countries include increased political or social instability, economies based on only a few industries, unstable currencies, runaway inflation, highly volatile securities markets, unpredictable shifts in policies relating to foreign investments, lack of protection for investors against parties that fail to complete transactions, and the potential for government seizure of assets or nationalization of companies.

Smaller Company Stock Risk. Small and mid cap stocks may be very sensitive to changing economic conditions and market downturns. In particular, the issuers of small company stocks often have more narrow markets for their products and services, fewer product lines, and more limited managerial and financial resources than larger issuers. The stocks of small companies may therefore be more volatile and the ability to sell these stocks at a desirable time or price may be more limited.

Growth Stock Risk. Growth stock prices may be more sensitive to changes in current or expected earnings than the prices of other stocks, and they may fall or not appreciate in step with the broader securities markets.

Sector Weightings Risk. To the extent the Fund emphasizes, from time to time, investments in a particular sector, the Fund will be subject to a greater degree to the risks particular to that sector, including the sectors described below. Market conditions, interest rates, and economic, regulatory, or financial developments could significantly affect all the securities in a single sector. If the Fund invests in a few sectors, it may have increased exposure to the price movements of those sectors.

Financials Sector Risk. The financials sector is subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by the availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition.

Consumer Discretionary Sector Risk. Industries in the consumer discretionary sector, such as consumer durables, hotels, restaurants, media, retailing and automobiles, may be significantly impacted by the performance of the overall economy, interest rates, competition, consumer confidence and spending, and changes in demographics and consumer tastes.

2

Health Care Sector Risk. Health care companies are strongly affected by worldwide scientific or technological developments. Their products may rapidly become obsolete. Many health care companies are also subject to significant government regulation and may be affected by changes in government policies.

Industrials Sector Risk. Industries in the industrials sector, such as companies engaged in the production, distribution or service of products or equipment for manufacturing, agriculture, forestry, mining and construction, can be significantly affected by general economic trends, including such factors as employment and economic growth, interest rate changes, changes in consumer spending, legislative and government regulation and spending, import controls, commodity prices, and worldwide competition.

Information Technology Sector Risk. Stocks of information technology companies may be volatile because issuers are sensitive to rapid obsolescence of existing technology, short product cycles, falling prices and profits, competition from new market entrants, and general economic conditions. Information technology stocks, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market.
