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 redeem all of your shares at the end of those periods. 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 costs would be:

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 or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 110% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Small Cap Growth Fund will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in equity securities of small companies. The Fund will invest primarily in common stocks of U.S. companies with market capitalizations in the range of companies in the Russell 2000 Index (between $2.70 million and $4.70 billion as of December 31, 2012) or the S&P SmallCap 600 Index (between $61.10 million and $3.80 billion as of December 31, 2012), each as determined at the time of purchase. The market capitalization range and the composition of the Russell 2000 Index and the S&P SmallCap 600 Index are subject to change. The Fund's investments in equity securities may include common and preferred stocks, warrants and, to a lesser extent, real estate investment trusts (REITs), exchange-traded funds (ETFs) and securities of large capitalization companies.

The Fund uses a multi-manager approach, relying upon a number of sub-advisers (each, a Sub-Adviser and collectively, the Sub-Advisers) to manage portions of the Fund's portfolio under the general supervision of SEI Investments Management Corporation (SIMC), the Fund's adviser. In managing its portion of the Fund's assets, each Sub-Adviser selects stocks it believes have attractive growth and appreciation potential in light of such characteristics as revenue and earnings growth, expectations from sell-side analysts and relative valuation, among other factors.

Principal Risks

Equity Market Risk — The risk that stock prices will fall over short or extended periods of time.

Exchange-Traded Funds (ETFs) Risk — The risks of owning shares of an ETF generally reflect the risks of owning the underlying securities the ETF is designed to track, although lack of liquidity in an ETF could result in its value being more volatile than the underlying portfolio securities.

Investment Style Risk — The risk that small capitalization securities may underperform other segments of the equity markets or the equity markets as a whole.

Liquidity Risk — The risk that certain securities may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Fund management or performance.

Portfolio Turnover Risk — Due to its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional capital gains tax liabilities.

REITs Risk — REITs are trusts that invest primarily in commercial real estate or real estate-related loans. The Fund's investments in REITs will be subject to the risks associated with the direct ownership of real estate. Risks commonly associated with the direct ownership of real estate include fluctuations in the value of underlying properties, defaults by borrowers or tenants, changes in interest rates and risks related to general or local economic conditions. Some REITs may have limited diversification and may be subject to risks inherent in financing a limited number of properties.

Small Capitalization Risk — Smaller capitalization companies in which the Fund invests may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, small capitalization companies may have limited product lines, markets and financial resources and may depend upon a relatively small management group. Therefore, small capitalization stocks may be more volatile than those of larger companies. Small capitalization stocks may be traded over-the-counter or listed on an exchange.

Loss of money is a risk of investing in the Fund.

[1] The Fund incurred Acquired Fund Fees and Expenses (AFFE) during the most recent fiscal year, and therefore the operating expenses in this fee table will not correlate to the expense ratio in the Fund's financial statements (or the "Financial Highlights" section in the prospectus). The financial statements include only the direct operating expenses incurred by the Fund, not the indirect costs of investing in other investment companies.
