Investment Objective

The U.S. Government Securities Ultra-Short Bond Fund (the “Fund”) seeks high current income consistent with preserving capital and maintaining liquidity.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in RidgeWorth Funds. More information about these and other discounts is available from your financial professional and in Sales Charges on page 90 of the Fund’s prospectus and Rights of Accumulations on page 91 of the Fund’s statement of additional information.

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

	I Shares
Management Fees		0.19%
Other Expenses		0.14%
Total Annual Fund Operating Expenses		0.33%

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. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same and you reinvest all dividends and distributions. 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
I Shares	$	34	$	106	$	186	$	420

Portfolio Turnover

The Fund pays transaction costs 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 229% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in short duration U.S. Treasury securities, U.S. agency securities, U.S. agency mortgage-backed securities, repurchase agreements, other U.S. government securities and shares of registered money market mutual funds that invest in the foregoing. The Fund expects to maintain an average effective duration between 3 months and 1 year. Individual purchases will generally be limited to securities with an effective duration of less than 5 years. Duration measures a bond or Fund’s sensitivity to interest rate changes and is expressed as a number of years. The higher the number, the greater the risk. Under normal circumstances, for example, if a portfolio has a duration of five years, its value will change by 5% if rates change by 1%. Shorter duration bonds result in lower expected volatility.

August 1, 2011 1 Summary Prospectus

In selecting securities for purchase and sale, the Fund’s Subadviser, StableRiver Capital Management LLC (“StableRiver” or the “Subadviser”), attempts to maximize income by identifying securities that offer an acceptable yield for a given maturity.

In addition, to implement its investment strategy, the Fund may buy or sell, to a limited extent, derivative instruments (such as futures, options and swaps) to use as a substitute for a purchase or sale of a position in the underlying assets and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate risk.

Principal Investment Risks

You may lose money if you invest in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Debt Securities Risk: Debt securities, such as bonds, involve credit risk. Credit risk is the risk that the borrower will not make timely payments of principal and interest. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. The degree of credit risk depends on the issuer’s financial condition and on the terms of the securities. Debt securities are also subject to interest rate risk, which is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter term securities.

Mortgage-Backed and Asset-Backed Securities Risk: Mortgage- and asset-backed securities are debt instruments that are secured by interests in pools of mortgage loans or other financial assets. The value of these securities will be influenced by the factors affecting the assets underlying such securities, swings in interest rates, changes in default rates, or deteriorating economic conditions. During periods of declining asset values, mortgage-backed and asset-backed securities may face valuation difficulties, become more volatile and/or illiquid. The risk of default is generally higher in the case of securities backed by loans made to borrowers with “sub-prime” credit metrics.

If market interest rates increase substantially and the Fund’s adjustable-rate securities are not able to reset to market interest rates during any one adjustment period, the value of the Fund’s holdings and its net asset value may decline until the adjustable-rate securities are able to reset to market rates. In the event of a dramatic increase in interest rates, the lifetime limit on a security’s interest rate may prevent the rate from adjusting to prevailing market rates. In such an event the security could underperform and affect the Fund’s net asset value.

Prepayment and Call Risk: During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or prepay the bond before its stated maturity date. When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest the proceeds in securities with a lower yield or fail to recover additional amounts paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decline in the Fund’s income.

Derivatives Risk: In the course of pursuing its investment strategies, the Fund may invest in certain types of derivatives including swaps, foreign currency forward contracts and futures. The Fund is exposed to additional volatility and potential loss with these investments. Losses in these investments may exceed the Fund’s initial investment. Derivatives may be difficult to value, may become illiquid and may not correlate perfectly with the overall securities market.

Futures Contract Risk: The Fund may enter into futures contracts. The risks associated with futures include: the Subadviser’s ability to manage these instruments, the potential inability to terminate or sell a position, the lack of a liquid secondary market for the Fund’s position and the risk that the counterparty to the transaction will not meet its obligations.

Swap Risk: The Fund may enter into swap agreements, including credit default and interest rate swaps, for purposes of attempting to gain exposure to a particular asset without actually purchasing that asset or to hedge a position. Credit default swaps may increase or decrease the Fund’s exposure to credit risk and could result in losses if the Subadviser does not correctly evaluate the creditworthiness of the entity on which the credit default swap is based. Swap agreements may also subject the Fund to the risk that the counterparty to the transaction may not meet its obligations.

Leverage Risk: Certain transactions and the use of derivatives such as swaps and futures may create leveraging risk. Leverage may cause the Fund to be more volatile than if the Fund had not been leveraged. This is because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities.

U.S. Government Issuers Risk: U.S. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of U.S. Treasury obligations to decline. Obligations of U.S. government agencies and authorities are supported by varying degrees of credit, but generally are not backed by the full faith and credit of the U.S. government. U.S. government debt securities may underperform other segments of the fixed income market or the fixed income market as a whole.
