Investment Objective

The Matson Money Fixed Income VI Portfolio seeks total return (consisting of current income and capital appreciation).

Expenses and Fees

This table describes the fees and expenses that you may pay if you buy and hold shares of the Portfolio. This table does not reflect the fees and expenses associated with any variable annuity contract or variable life insurance policy that uses the Portfolio as an investment option. Had those fees and expenses been included, overall fees and expenses would be higher.

Annual Portfolio Operating Expenses (expenses that you pay each year as a percentage
of the value of your investment)

Management Fees	0.50	%
Distribution (12b-1) and/or Service Fees	None
Other Expenses	0.87	%
Acquired Fund Fees and Expenses	0.19	%
Total Annual Portfolio Operating Expenses	1.56	%
Fee Waiver and/or Expense Reimbursement(1)	(0.37	)%
Total Annual Portfolio Operating Expenses after Fee Waiver and/or Expense Reimbursement	1.19	%

(1)  Matson Money, Inc. has contractually agreed to waive management fees and reimburse expenses for the Matson Money Fixed Income VI Portfolio to the extent that Total Annual Fund Operating Expenses (excluding certain items discussed below) exceed 1.00%. In determining the Adviser's obligation to waive advisory fees and/or reimburse expenses, the following expenses are not taken into account and certain of these expenses could cause net Total Annual Fund Operating Expenses to exceed 1.00%: acquired fund fees and expenses, brokerage commissions, extraordinary items, interest or taxes. This contractual limitation is in effect until December 31, 2016 and may not be terminated without the approval of the Board of Directors of The RBB Fund, Inc. The Adviser may discontinue these arrangements any time after December 31, 2016.

Example

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. This Example does not reflect the fees and expenses associated with any variable annuity contract or variable life insurance policy that uses the Portfolio as an investment option. Had those fees and expenses been included, the costs shown below would be higher.

The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and that you sell your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year

1

and that the Portfolio's operating expenses remain the same. Although your actual costs and returns might be higher or lower, based on these assumptions your costs would be:

1 Year		3 Years		5 Years		10 Years
$	121	$	456	$	815	$	1,825

Portfolio Turnover

The Portfolio 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 Portfolio shares are held in a taxable account. These costs, which are not reflected in Total Annual Portfolio Operating Expenses or in the Example, affect the Portfolio's performance. During the fiscal year ended August 31, 2015, the Portfolio's portfolio turnover rate was 10.90% of the average value of its portfolio.

Summary of Principal Investment Strategies

The Portfolio pursues its investment objective by investing under normal circumstances at least 80% of its net assets, including any borrowings for investment purposes, in shares of registered, open-end investment companies and exchange-traded funds ("ETFs") (collectively, "investment companies") that have either adopted policies to invest at least 80% of their assets in fixed income securities that the Adviser believes offer the prospect of providing total return, or invest substantially all of their assets in such fixed income securities. The purchase of shares of investment companies may result in duplication of expenses, including advisory fees, in addition to the Portfolio's own expenses.

Under normal market conditions, the Adviser expects substantially all of the Portfolio's net assets to be invested in the securities of investment companies, including other investment companies funded by insurance company separate accounts, that invest in the types of securities described in each asset class below, with less than 2% of the net assets invested in cash or money market instruments.

One-Year Fixed Income Asset Class: The underlying investment companies generally will purchase U.S. government obligations, U.S. government agency obligations, dollar-denominated obligations of foreign issuers issued in the U.S., foreign government and agency obligations, bank obligations, including the obligations of U.S. subsidiaries and branches of foreign banks, corporate obligations, commercial paper, repurchase agreements, and obligations of supranational organizations such as the World Bank, the European Investment Bank and the Inter-American Development Bank. Generally, obligations comprising this asset class will mature within one year from the date of settlement, but substantial investments may be made in obligations maturing within two years from the date of settlement when greater returns are available.

Two-Year Global Fixed Income Asset Class: The underlying investment companies generally will purchase obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, corporate debt obligations, bank obligations, commercial paper, repurchase agreements, and other debt obligations of domestic and foreign issuers. Generally, obligations comprising this asset class have a weighted average maturity not exceeding two years, but investments may be made in obligations maturing in a shorter time period (from overnight to less than two years from the date of settlement). Because many of the investments of the underlying investment companies in this asset class will be denominated in foreign currencies, the underlying investment companies may also enter into forward foreign currency contracts to attempt to protect against uncertainty in the level of future foreign currency rates, to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another.

Intermediate Government Fixed Income Asset Class: The underlying investment companies generally will purchase debt obligations of the U.S. government and U.S. government agencies. Generally, investment companies in the asset class will purchase securities with maturities of between five and fifteen years, however such investment companies ordinarily will have an average weighted maturity of between three and ten years.

2

Five-Year Global Fixed Income Asset Class: The underlying investment companies generally will purchase obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, obligations of other foreign issuers, corporate debt obligations, bank obligations, commercial paper, and obligations of supranational organizations. Generally, obligations comprising this asset class have a weighted average maturity not exceeding five years. However, investments may be made in obligations maturing in a shorter time period (from overnight to less than five years from the date of settlement.) Because many of the investments of the underlying investment companies in this asset class will be denominated in foreign currencies, the underlying investment companies may also enter into forward foreign currency contracts to attempt to protect against uncertainty in the level of future foreign currency rates, to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another.

The underlying investment companies may also use derivatives, such as futures contracts and options on futures contracts for equity securities and indices, to gain market exposure on its uninvested cash pending investment in securities or to maintain liquidity to pay redemptions. Underlying index-based ETFs may use derivatives, including futures contracts, options on futures contracts, forward currency contracts, options and swaps to help the ETF track its underlying index.

Certain underlying investment companies may concentrate their investments (invest more than 25% of its total assets) in obligations of U.S. and foreign banks and bank holding companies when the yield to maturity on eligible portfolio investments in banking securities as a group generally exceeds the yield to maturity on all other eligible portfolio investments as a group generally for a period of five consecutive days when the New York Stock Exchange is open for trading. While the Portfolio will not concentrate its investments in any one industry, the Portfolio may be focused on banking sectors under certain circumstances.

The Portfolio reserves the right to hold up to 100% of its assets as a temporary defensive measure in cash and money market instruments such as U.S. Government securities, bank obligations and commercial paper. To the extent the Portfolio employs a temporary defensive measure, the Portfolio may not achieve its investment objective. Periodically the Adviser will review the allocations for the Portfolio in each underlying investment company and may add or remove underlying investment companies and/or change the investment allocation percentages of the Portfolio in the underlying investment companies without notice to shareholders or the holders of the variable annuity or variable life insurance policies.

Summary of Principal Risks

As with all mutual funds, a shareholder is subject to the risk that his or her investment could lose money. An investment in the Portfolio involves the same investment risks as those of the underlying investment companies in which the Portfolio invests. These risks may adversely affect the Portfolio's net asset value ("NAV") and investment performance. The Portfolio is subject to the following principal risks:

•  Fixed income securities in which the Portfolio's underlying investment companies may invest are subject to certain risks, including: interest rate risk, reinvestment risk, prepayment and extension risk, credit/default risk, and the risks associated with investing in repurchase agreements.

•  Interest rate risk involves the risk that prices of fixed income securities will rise and fall in response to interest rate changes.

•  Reinvestment risk involves the risk that proceeds from matured investments may be re-invested at lower interest rates.

•  Prepayment risk involves the risk that in declining interest rates environments prepayments of principal could increase and require the Portfolio to reinvest proceeds of the prepayments at lower interest rates.

3

•  Extension risk involves the risk that prepayments of principal will decrease when interest rates rise resulting in a longer effective maturity of a security.

•  Credit risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal when due. Credit risk also involves the risk that the credit rating of a security may be lowered.

•  Repurchase agreement risk involves the risk that the other party to a repurchase agreement will be unable to complete the transaction and the underlying investment company in which the Portfolio invests may suffer a loss as a result.

•  Because the Portfolio owns shares of underlying investment companies that invest in foreign issuers, the Portfolio is subject to risks presented by investments in such issuers. Securities of foreign issuers may be negatively affected by political events, economic conditions, or inefficient, illiquid or unregulated markets in foreign countries. Foreign issuers may be subject to inadequate regulatory or accounting standards.

•  Currency risk is the risk that exchange rates for currencies in which securities held by the underlying investment companies in which the Portfolio invests are denominated will fluctuate daily. Forward foreign currency exchange contracts may limit potential gains from a favorable change in value between the U.S. dollar and foreign currencies. Unanticipated changes in currency pricing may result in poorer overall performance for the Portfolio than if it had not engaged in these contracts.

•  The Adviser's judgment about the attractiveness or potential appreciation of a particular underlying investment company security could prove to be wrong or the Portfolio could miss out on an investment opportunity because the assets necessary to take advantage of such opportunity are tied up in less advantageous investments.

•  Because under normal circumstances the Portfolio invests at least 80% of its net assets in shares of registered investment companies that emphasize investments in fixed income securities, the NAV of the Portfolio will change with changes in the share prices of the investment companies in which the Portfolio invests.

•  Not all obligations of U.S. government agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. Some are backed only by the credit of the issuing agency or instrumentality. Accordingly, there may be some risk of default by the issuer in such cases.

•  There is a risk that the Portfolio, which is passively managed, may not perform as well as funds with more active methods of investment management, such as selecting securities based on economic, financial, and market analysis.

•  The derivative instruments in which the underlying investment companies may invest are subject to a number of risks including liquidity, interest rate, market, credit and management risks, and the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and it is possible to lose more than the principal amount invested.

•  The performance of the Portfolio will depend on how successfully the investment adviser(s) to the underlying investment companies pursue their investment strategies.

•  Banks are very sensitive to changes in money market and general economic conditions. Adverse general economic conditions can cause financial difficulties for a bank's borrowers and the borrowers' failure to repay their loans can adversely affect the bank's financial situation. Banks are subject to extensive regulation and decisions by regulators may limit the loans banks make and the interest rates and fees they charge, which could reduce bank profitability.

Individual investors may purchase or redeem Portfolio shares indirectly through variable annuity contracts and variable life insurance policies offered through the separate accounts.

Taxes

Provided that the Portfolio and separate accounts investing in the Portfolio satisfy applicable tax requirements, the Portfolio will not be subject to federal tax, and the separate accounts will not be taxable on distributions from, or gains with respect to, the Portfolio. Special tax rules apply to life insurance companies, variable annuity contracts and variable life insurance contracts. For information on federal income taxation of owners of variable annuity or variable life insurance contracts, see the prospectus for the applicable contract.

Payments to Broker-Dealers and Other Financial Intermediaries

The Portfolio may pay participating insurance companies and securities dealers for the sale of Portfolio shares and other related services. These payments may create a conflict of interest by influencing the insurance company and your salesperson to recommend the Portfolio over another investment. Ask your salesperson or visit your insurance company's website for more information.
