Supplement dated May 22, 2015 to the

Summary Prospectus, Prospectus and Statement of Additional Information (“SAI”)

each dated August 1, 2014

RidgeWorth Intermediate Bond Fund (A, R & I Shares)

The information in this supplement updates information in, and should be read in conjunction with, the Summary Prospectus, Prospectus and SAI.

On May 21, 2015, the Board of Trustees (the “Board”) of RidgeWorth Funds (the “Trust”) approved the reorganization of the RidgeWorth Intermediate Bond Fund (the “Fund”) into the RidgeWorth Core Bond Fund (the “Acquiring Fund”), a separate series of the Trust.

After careful review, the Board determined the reorganization to be in the best interests of the Fund’s shareholders. In making its determination, the Board considered that:

• the Fund’s investment objective is substantially similar to that of the Acquiring Fund;

• the Fund’s policies and strategies are substantially similar to those of the Acquiring Fund;

• the Fund’s fundamental investment limitations are the same as those of the Acquiring Fund;

• the Fund’s contractual advisory fee is the same as that of the Acquiring Fund;

• in connection with the reorganization, the 12b-1 fee for the Acquiring Fund’s A Shares will be reduced from 0.30% to 0.25% to match the current 12b-1 fee of the Fund’s A Shares;

• the total operating expenses of the Acquiring Fund’s A Shares, I Shares, and R Shares will be the same as or lower than those of the corresponding share class of the Fund after the reduction of the Acquiring Fund’s A Shares 12b-1 fee;

• shareholders of the Fund’s A Shares, R Shares and I Shares will receive shares of the Acquiring Fund’s A Shares, R Shares and I Shares, respectively;

• the reorganization is expected to be a tax-free event to shareholders of the Fund; and

• economies of scale may result from the reorganization for shareholders of the Fund.

The reorganization is expected to be effective at the close of business on or about July 31, 2015. At that time, each shareholder of the A, R and I Shares of the Fund will become a shareholder of the Acquiring Fund and will receive corresponding A, R and I Shares of the Acquiring Fund in an amount equal in value to the shares of the Fund the shareholder had immediately before the reorganization.

The Acquiring Fund invests at least 80% of its net assets in investment grade fixed income securities. The Fund invests at least 80% of its net assets in fixed income securities. The primary difference between the Fund and the Acquiring Fund is that the Fund focuses on intermediate-term fixed income securities and may purchase floating rate loans.

Effective August 1, 2015, the Acquiring Fund will be renamed the RidgeWorth Seix Core Bond Fund and its investment objective will be as follows:

The RidgeWorth Seix Core Bond Fund seeks to maximize long term total return through a combination of current income and capital appreciation, consistent with capital preservation.

Shareholders who wish to redeem shares of the Fund in a taxable transaction prior to the reorganization may do so in accordance with the procedures described in the Fund’s Prospectus.

Effective on the date of the reorganization, all references to the Fund in the Prospectus and SAI are hereby deleted.

RidgeWorth U.S. Government Securities Fund (A, C & I Shares)

The information in this supplement updates information in, and should be read in conjunction with, the Summary Prospectus, Prospectus and SAI.

On May 21, 2015, the Board of Trustees (the “Board”) of RidgeWorth Funds (the “Trust”) approved the reorganization of the RidgeWorth U.S. Government Securities Fund (the “Fund”) into the RidgeWorth Limited-Term Federal Mortgage Securities Fund (the “Acquiring Fund”), a separate series of the Trust.

After careful review, the Board determined the reorganization to be in the best interests of the Fund’s shareholders. In making its determination, the Board considered that:

• the Fund’s investment objective is currently the same as that of the Acquiring Fund;

• the Fund’s policies and strategies are substantially similar to those of the Acquiring Fund;

• the Fund’s fundamental investment limitations are the same as those of the Acquiring Fund;

• the Fund’s contractual advisory fee is currently the same as that of the Acquiring Fund;

• the Fund’s 12b-1 fee for each share class is the same as or higher than the 12b-1 fee for the corresponding share class of the Acquiring Fund;

• the total operating expenses of each share class of the Acquiring Fund, after fee waivers and/or expense reimbursements, are the same as or lower than the total operating expenses of the corresponding share class of the Fund;

• shareholders of the Fund’s A Shares, C Shares and I Shares will receive shares of the Acquiring Fund’s A Shares, C Shares and I Shares, respectively; and

• economies of scale may result from the reorganization for shareholders of the Fund.

The reorganization is expected to be effective at the close of business on or about July 31, 2015. At that time, each shareholder of the A, C and I Shares of the Fund will become a shareholder of the Acquiring Fund and will receive corresponding A, C and I Shares of the Acquiring Fund in an amount equal in value to the shares of the Fund the shareholder had immediately before the reorganization.

Depending on shareholder and investment activity that occurs prior to the reorganization, the reorganization may be a taxable event to the Fund’s shareholders.

The Acquiring Fund invests at least 80% of its net assets in U.S. government agency mortgage-backed securities, such as the Federal National Mortgage Association, Government National Mortgage Association and collateralized mortgage obligations. The Fund invests at least 80% of its net assets in securities that are guaranteed or sponsored by the U.S. government, which consist of U.S. Treasury securities and securities issued by U.S. government agencies, instrumentalities, and government-sponsored entities, including mortgage-backed securities. The primary difference between the Fund and the Acquiring Fund is that the Acquiring Fund focuses on U.S. government agency mortgage-backed securities and, historically, the Fund has focused on U.S. Treasury securities.

Effective August 1, 2015, the Acquiring Fund will be renamed the RidgeWorth Seix U.S. Mortgage Fund and its investment objective will be as follows:

The RidgeWorth Seix U.S. Mortgage Fund seeks to maximize long term total return through a combination of current income and capital appreciation, consistent with capital preservation.

Also effective on August 1, 2015, the investment advisory fee for the Acquiring Fund will be reduced from 0.50% to 0.40% of average daily net assets.

Shareholders who wish to redeem shares of the Fund in a taxable transaction prior to the reorganization may do so in accordance with the procedures described in the Fund’s Prospectus.

Effective on the date of the reorganization, all references to the Fund in the Prospectus and SAI are hereby deleted.
