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 Retail Shares or Class C Shares or $1,000,000 in the Class I Shares of the Fund and 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 Small Cap Low Volatility Fund - USD ($)	1 Year	3 Years
Class I	12,532	104,997
Retail Class	151	1,123
Class C	226	1,337

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 Total Annual Fund Operating Expenses or in the Example, affect the Fund's performance. For the period from the Fund's inception on March 31, 2016 to the fiscal period ended August 31, 2016, the Fund's portfolio turnover rate was 0.01% of the average value of its portfolio.

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 U.S. issuers with small market capitalizations. A small market capitalization issuer generally is considered to be one whose market capitalization is, at the time the Fund makes the investment, similar to the market capitalization of companies in the Russell 2000^® Index. The Russell 2000^® Index is a small cap stock market index measuring the performance of approximately 2,000 small cap U.S. companies. As of November 30, 2016, the median market capitalization of this index was $780 million and the largest stock was $8.3 billion. 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 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 Russell 2000^® Index. Volatility is a statistical measurement of the magnitude of up and down fluctuations in the value of a financial instrument or 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 Adviser selects securities for the Fund that it anticipates will produce less volatility with more protection against significant losses and more consistent returns. While the Adviser attempts to manage the Fund's volatility, there is no guarantee that the strategy will be successful or that the Fund's portfolio will not experience periods of volatility.

The Fund may sell a stock if it no longer meets one or more investment criteria, including if the Adviser identifies fundamental, governance or legal risks or if the risk/return ranking declines due to increasing risk and/or decreasing return potential.

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:

·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.

·Convertible Securities Risk. Securities that can be converted into common stock, such as certain securities and preferred stock, are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to the risks associated with equity securities

·High Portfolio Turnover Risk. The risk that when investing on a shorter-term basis, the Fund may as a result trade more frequently and incur higher levels of brokerage fees and commissions and cause higher levels of current tax liability to shareholders of the Fund. A portfolio turnover rate of 100% is considered to be high. For the fiscal period, the annual portfolio turnover rate of the Fund was lower than 100%, but the Fund's portfolio turnover rate is expected to vary from year to year. The Adviser may engage in active trading, and will not consider portfolio turnover a limiting factor in making decisions for the Fund.

·Low Volatility Risk. Although subject to the risks of common stocks, low volatility stocks are seen as having a lower risk profile than the overall markets. However, a portfolio comprised of low volatility stocks may not produce investment exposure that has lower variability to changes in such stocks' price levels. Investing in low volatility stocks may limit the Fund's gains in rising markets.

·Management Risk. The Fund is subject to the risk of poor 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.

·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 Adviser believes will produce less volatility, there is no guarantee that the stocks will perform as expected.

·New Fund Risk. As a new Fund, there can be no assurance that the Fund will grow to or maintain economically viable size. In addition, the Fund has a limited operating history upon which prospective investors can evaluate its performance.

·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.

·Small Cap Risk. Stocks of small companies may be more volatile than, and not as readily marketable as, those of larger companies. Small companies may also have limited product lines, markets or financial resources and may be dependent on relatively small or inexperienced management groups. Additionally, the trading volume of small company securities may make them more difficult to sell than those of larger companies. Moreover, the lack of an efficient market for the securities may make them difficult to value.

·Warrants Risk. The purchase of warrants involves the risk that the Fund could lose the purchase value of a warrant if the right to subscribe to additional shares is not executed prior to the warrant's expiration. Also, the purchase of warrants involves the risk that the effective price paid for the warrant added to the subscription price of the related security may exceed the value of the subscribed security's market price such as when there is no movement in the level of the underlying security.

Performance Information

Because the Fund has less than one full calendar year of performance, no performance information has been included.

[1] Other Expenses are estimated for the current fiscal year.

[2] Summit Global Investments, LLC (the "Adviser"), the Fund's investment adviser, has contractually agreed to waive management fees and reimburse expenses through December 31, 2017 to the extent that Total Annual Fund Operating Expenses (excluding certain items discussed below) exceed 1.23%, 1.48% and 2.23% of the Fund's average daily net assets attributable to Class I Shares, Retail Shares and Class C Shares, respectively. In determining the 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%, 1.48% or 2.23%, as applicable: acquired fund fees and expenses, brokerage commissions, extraordinary items, interest or taxes. This contractual limitation may not be terminated before December 31, 2017 without the approval of the Board of Directors of The RBB Fund, Inc. If at any time the Fund's Total Annual Fund Operating Expenses (not including acquired fund fees and expenses, brokerage commissions, extraordinary items, interest or taxes) for a year are less than 1.23%, 1.48% and 2.23% of the Fund's average daily net assets attributable to Class I Shares, Retail Class Shares and Class C Shares, respectively, the Adviser is entitled to reimbursement by the Fund of the advisory fees forgone and other payments remitted by the Adviser to the Fund within three years from the date on which such waiver or reimbursement was made, provided such reimbursement does not cause the Fund to exceed expense limitations that were in effect at the time of the waiver or reimbursement.
