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, that the Fund’s operating expenses remain the same and that you reinvest all dividends and distributions. The example reflects contractual fee waivers and reimbursements for the first year only. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example RidgeWorth U.S. Government Securities Fund (USD $)	1 Year	3 Years	5 Years	10 Years
A Shares	567	780	1,010	1,672
C Shares	273	539	929	2,025
I Shares	77	257	454	1,022

You would pay the following expenses if you did not redeem your shares:

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 75% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities that are guaranteed or sponsored by the U.S. government. U.S. government securities are U.S. Treasury securities and securities issued by U.S. government agencies, instrumentalities, and government-sponsored entities, including mortgage-backed securities.

Buy and sell decisions are based on a wide number of factors that determine the risk-reward profile of each security within the context of the broader portfolio. In selecting investments for purchase and sale, the Fund's Subadviser, Seix Investment Advisors LLC ("Seix" or the "Subadviser"), attempts to provide a relatively high dividend. Under certain circumstances, the Subadviser may position the Fund's exposure across the yield curve to potentially benefit from a normalization of the term structure of rates (i.e., in an environment where the yield curve is abnormally steep, investments will be positioned along the yield curve to benefit as the curve's shape reverts to a more traditional, or normal slope).

The Subadviser seeks to maintain an overall portfolio modified adjusted duration of 4-7 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. The Fund may invest a portion of its assets in securities that are restricted as to resale.

The Fund may use U.S. Treasury Securities futures as a vehicle to adjust duration and manage its interest rate exposure.

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 or interest or will default. 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.

Futures Contract Risk: 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, mispricing or improper valuation and that the other party to a derivative transaction will not meet its obligations. The prices of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility and unexpected losses.

A liquid secondary market may not always exist for the Fund's derivative positions at any time. In fact, many over-the-counter instruments (instruments not traded on exchange) may not be liquid. Over-the-counter instruments also involve the risk that the other party to the derivative transaction will not meet its obligations.

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 and may 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.

U.S. Government Securities Risk: U.S. Treasury securities are backed by the full faith and credit of the U.S. government, while other types of securities issued or guaranteed by federal agencies, instrumentalities, and U.S. government-sponsored entities may or may not be backed by the full faith and credit of the U.S. government. U.S. government securities may underperform other segments of the fixed income market or the fixed income market as a whole.
