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 Class A and Retail Shares or $1,000,000 in the Class I
Shares of 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:

Expense Example Summit Global Investments U.S. Low Volatility Equity Fund (USD $)	Expense Example, With Redemption, 1 Year	Expense Example, With Redemption, 3 Years
Class A	644	1,035
Retail Class	125	538
Class I	9,997	46,118

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 transactions 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.

Principal Investment Strategies

Under normal circumstances, the Fund will invest at least 80% of its net assets
(including borrowings for investment purposes) in equity securities, primarily
common stocks, of companies within the Russell 1000® Index and S&P 500® Index .
The Fund's investments will generally consist of securities, which may include
common stocks, preferred stocks, warrants to acquire common stock, and
securities convertible into common stock. The Fund purchases equity securities
traded in the U.S. on registered exchanges or the over-the-counter market.

The Fund's investment adviser attempts to lower the Fund's market risk by
investing in U.S. equity securities that lower the overall volatility of the
Fund's portfolio as compared to the S&P 500® Index. The Fund invests in stocks
that exhibit less volatile stock price patterns, strengthening business metrics
(i.e., earnings, debt, return on assets, competition, customers, industry, etc.)
and quantitative factors such as earnings variability, leverage, volatility,
price/book, price/cash flow, etc. The Fund's investment adviser selects
securities for the Fund that it anticipates will produce less volatility with
more capital protection and more consistent returns.

Principal Risks

Loss of money is a risk of investing in the Fund. In addition, your investment
in the Fund may be subject to the following principal risks:

o Common Stock Risk. Investments in common stocks are subject to market,
economic and business risks that will cause their price to fluctuate over time.
Therefore, an investment in the Fund may be more suitable for long-term
investors who can bear the risk of these fluctuations.

o Management Risk. The Fund is subject to the risk of poor management stock
selection. In other words, the individual stocks in the Fund may not perform as
well as expected, and/or the Fund's portfolio management practices do not work
to achieve their desired result.

o Market Risk. The net asset value ("NAV") of the Fund will change with changes
in the market value of its portfolio positions. Investors may lose money.
Although the Fund will invest in stocks the Fund's investment adviser believes
will produce less volatility, there is no guarantee that the stocks will perform
as expected.

o Opportunity Risk. As with all mutual funds, the Fund is subject to the risk of
missing out on an opportunity because the assets necessary to take advantage of
it are tied up in less advantageous investments.

Performance Information

No performance information is available for the Fund because it had not
commenced operations as of the date of this Prospectus. The Fund intends to
evaluate its performance as compared to that of the S&P 500® Index.

In determining the investment adviser's obligation to waive advisory fees and/or reimburse expenses, the following expenses are not taken into account and could cause net Total Annual Fund Operating Expenses to exceed 1.23% or 0.98%, as applicable: acquired fund fees and expenses, brokerage commissions, extraordinary items, interest or taxes. This contractual limitation may not be terminated before March 1, 2013 without the approval of the Board of Directors of The RBB Fund, Inc.
