RIDGEWORTH FUNDS Supplement dated April 26, 2017 to the Summary Prospectus and Prospectus dated August 1, 2016 and the Statement of Additional Information dated March 31, 2017, as each may be supplemented or revised RidgeWorth Capital Innovations Global Resources and Infrastructure Fund (the Fund ) The information in this supplement updates information in, and should be read in conjunction with, the Summary Prospectus, Prospectus and Statement of Additional Information. On April 17, 2017, the Board of Trustees (the Board ) of RidgeWorth Funds approved an Agreement and Plan of Reorganization (the Plan of Reorganization ) relating to the proposed reorganization (the Reorganization ) of the Fund, a series of RidgeWorth Funds, into a newly created series of Investment Managers Series Trust ( IMST ). The Reorganization is subject to the completion of certain conditions, including approval by shareholders of the Fund. Under the Plan of Reorganization, the Fund would reorganize into a series of IMST (the Acquiring Fund ) on or about June 30, 2017. Oak Ridge Investments, LLC ( Oak Ridge ) will replace RidgeWorth Capital Management LLC ( RidgeWorth ) as investment adviser. Capital Innovations, LLC will continue as subadviser to the Fund and provide day-to-day portfolio management. It is expected that the investment objective of the Fund and the Acquiring Fund will be the same and the investment strategies will be substantially similar. RidgeWorth believes the Reorganization will benefit the Fund and its shareholders by offering them, among other things: The continued ability to benefit from the experience of the same portfolio managers currently managing the Fund; and Anticipated net total operating expenses for all classes of shares that, on a net basis under a contractual expense limitation agreement with Oak Ridge, are expected to be equal to or lower than current net operating expenses for a two-year period from the date of the Reorganization; and Opportunities for increased asset growth and improved economies of scale, over the long term. Proxy materials describing the Reorganization and the Board s considerations in approving the proposal will be mailed to shareholders of record of the Fund in anticipation of a Special Meeting of Shareholders scheduled for June 28, 2017. As a result of the Reorganization, shareholders of the Fund would become shareholders of the Acquiring Fund and would receive shares of the Acquiring Fund equal in aggregate net asset value to the shares of the Fund held immediately prior to the Reorganization. If the Reorganization is approved by shareholders and consummated, Fund shareholders who do not wish to become shareholders of the Acquiring Fund may redeem shares of the Fund prior to the Reorganization. The Reorganization may be terminated before the closing date of the Reorganization by action of either the Board or the Board of Trustees of IMST. The foregoing is not an offer to sell, nor a solicitation of an offer to buy, shares of the Fund or Acquiring Fund, nor is it a solicitation of any proxy. Shareholders of the Fund are urged to read the Combined Proxy Statement and Prospectus when it becomes available as it will contain information with respect to the investment objective, strategies, risks, policies, charges, and expenses of the Acquiring Fund, as well as other important information about the Reorganization.

VALUE FUNDS 1 CEREDEX LARGE CAP VALUE EQUITY FUND Summary Section A Shares, C Shares, I Shares and IS Shares Investment Objective The Ceredex Large Cap Value Equity Fund (the Fund ) seeks to provide a high level of capital appreciation. As a secondary goal, the Fund also seeks to provide current income. 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 38 of the Fund s prospectus and Rights of Accumulation on page 89 of the Fund s statement of additional information.

This agreement may be terminated upon written notice to the Adviser by RidgeWorth Funds. 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 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, 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: 1 year 3 years 5 years 10 years A Shares $694 $972 $1,270 $2,116 C Shares $274 $539 $ 928 $2,019 I Shares $ 99 $335 $ 589 $1,318 IS Shares $ 74 $230 $ 401 $ 894 You would pay the following expenses if you did not redeem your shares: 1 year 3 years 5 years 10 years A Shares $694 $972 $1,270 $2,116 C Shares $174 $539 $ 928 $2,019 I Shares $ 99 $335 $ 589 $1,318 IS Shares $ 74 $230 $ 401 $ 894 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 66% 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 U.S.-traded equity securities of large-capitalization companies. U.S.-traded equity securities may include American Depositary Receipts ( ADRs ). Ceredex Value Advisors LLC ( Ceredex or the Subadviser ) considers large-capitalization companies to be companies with market capitalizations similar to those of companies in the Russell 1000 Value Index. As of July 1, 2016, the market capitalization range of companies in the Russell 1000 Value Index was approximately $1.40 billion and above. As a result of its investment strategy, the Fund s portfolio turnover rate may be 100% or more.

2 VALUE FUNDS CEREDEX LARGE CAP VALUE EQUITY FUND In selecting investments for purchase and sale, the Subadviser chooses companies that it believes are undervalued in the market relative to the industry sector and the company s own valuation history. The Subadviser evaluates potential catalysts that may cause an upward re-rating of the stock s valuation. The common stocks purchased for the Fund generally pay dividends at the time of purchase or are expected to pay dividends soon after their purchase. 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. ADR Risk: Investments in ADRs involve risks similar to those accompanying direct investments in foreign securities. These include the risk that political and economic events unique to a country or region will affect those markets and their issuers. Equity Securities Risk: The price of equity securities fluctuates from time to time based on changes in a company s financial condition or overall market and economic conditions. As a result, the value of the Fund s equity securities may fluctuate drastically from day to day. Frequent Trading Risk: Frequent buying and selling of investments may involve higher trading costs and other expenses and may affect the Fund's performance over time. High rates of portfolio turnover may result in the realization of short-term capital gains and losses. The payment of taxes on these gains could adversely affect your after tax return on your investment in the Fund. Any distributions resulting from such gains or losses may be considered ordinary income for federal income tax purposes. Large-Capitalization Companies Risk: Large-cap stocks can perform differently from other segments of the equity market or the equity market as a whole. Large-capitalization companies may be less flexible in evolving markets or unable to implement change as quickly as small-capitalization companies. Value Investing Risk: Value investing attempts to identify strong companies whose stocks are selling at a discount from their perceived true worth. It is subject to the risk that the stocks intrinsic values may never be fully recognized or realized by the market, their prices may go down, or that stocks judged to be undervalued by the Fund may actually be appropriately priced. Performance The bar chart and the performance table that follow illustrate the risks and volatility of an investment in the Fund. The Fund s past performance (before and after taxes) does not indicate how the Fund will perform in the future. Updated performance information is available by contacting the RidgeWorth Funds at 1-888-784-3863 or by visiting www.ridgeworth.com. The annual returns in the bar chart which follows are for the I Shares without reflecting payment of any sales charge; if they did reflect such payment of sales charges, annual returns would be lower.

After-tax returns are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state and local taxes. Your actual after-tax

VALUE FUNDS 3 CEREDEX LARGE CAP VALUE EQUITY FUND returns will depend on your tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their Fund shares through tax-advantaged arrangements, such as 401(k) plans or individual retirement accounts ( IRAs ). After-tax returns are shown for only the I Shares. After-tax returns for other share classes will vary. In some cases, average annual return after taxes on distributions and sale of fund shares is higher than the average annual return after taxes on distributions because of realized losses that would have been sustained upon the sale of fund shares immediately after the relevant periods. The calculations assume that an investor holds the shares in a taxable account, is in the actual historical highest individual federal marginal income tax bracket for each year and would have been able to immediately utilize the full realized loss to reduce his or her federal tax liability. However, actual individual tax results may vary and investors should consult their tax advisers regarding their personal tax situations. Investment Adviser and Subadviser RidgeWorth Investments is the Fund s investment adviser (the Adviser ). Ceredex Value Advisors LLC is the Fund s Subadviser. Tax Information The Fund s distributions are generally taxable as ordinary income, qualified dividend income, or capital gains unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an IRA, which may be taxed upon withdrawal. Payments to Broker-Dealers and Other Financial Intermediaries If you purchase shares of the Fund through a financial intermediary, such as a broker-dealer or investment adviser, the Fund, the Adviser or the Distributor may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other financial intermediary and your salesperson to recommend the Fund over another investment. Ask your financial intermediary or visit your financial intermediary s website for more information. Portfolio Management Mr. Mills Riddick, CFA, Chief Investment Officer of Ceredex, has managed the Fund since 1995.

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: 1 year 3 years 5 years 10 years A Shares $707 $1,001 $1,315 $2,205 C Shares $281 $ 560 $ 964 $2,095 I Shares $114 $ 356 $ 617 $1,363 IS Shares $ 82 $ 255 $ 444 $ 990 You would pay the following expenses if you did not redeem your shares: 1 year 3 years 5 years 10 years A Shares $707 $1,001 $1,315 $2,205 C Shares $181 $ 560 $ 964 $2,095 I Shares $114 $ 356 $ 617 $1,363 IS Shares $ 82 $ 255 $ 444 $ 990 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 98% 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 U.S.-traded equity securities of mid-capitalization companies. U.S.-traded equity securities may include American Depositary Receipts ( ADRs ). Ceredex Value Advisors LLC ( Ceredex or the Subadviser ) considers mid-capitalization companies to be companies with market capitalizations similar to those of companies in the Russell Midcap Index. As of July 1, 2016, the market capitalization range of companies in the Russell Midcap Index was between approximately $1.40 billion and $28.6 billion. As a result of its investment strategy, the Fund s portfolio turnover rate may be 100% or more.

VALUE FUNDS 5 CEREDEX MID-CAP VALUE EQUITY FUND In selecting investments for purchase and sale, the Subadviser chooses companies that it believes are undervalued in the market relative to the industry sector and the company s own valuation history. The Subadviser evaluates potential catalysts that may cause an upward re-rating of the stock s valuation. The common stocks purchased for the Fund generally pay dividends at the time of purchase or are expected to pay dividends soon after their purchase. 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. ADR Risk: Investments in ADRs involve risks similar to those accompanying direct investments in foreign securities. These include the risk that political and economic events unique to a country or region will affect those markets and their issuers. Equity Securities Risk: The price of equity securities fluctuates from time to time based on changes in a company s financial condition or overall market and economic conditions. As a result, the value of the Fund s equity securities may fluctuate drastically from day to day. Frequent Trading Risk: Frequent buying and selling of investments may involve higher trading costs and other expenses and may affect the Fund's performance over time. High rates of portfolio turnover may result in the realization of short-term capital gains and losses. The payment of taxes on these gains could adversely affect your after tax return on your investment in the Fund. Any distributions resulting from such gains or losses may be considered ordinary income for federal income tax purposes. Mid-Capitalization Companies Risk: Mid-capitalization stocks tend to perform differently from other segments of the equity market or the equity market as a whole, and can be more volatile than stocks of large-capitalization companies. Midcapitalization companies may be newer or less established, and may have limited resources, products and markets, and may be less liquid. Value Investing Risk: Value investing attempts to identify strong companies whose stocks are selling at a discount from their perceived true worth. It is subject to the risk that the stocks intrinsic values may never be fully recognized or realized by the market, their prices may go down, or that stocks judged to be undervalued by the Fund may actually be appropriately priced.

After-tax returns are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state and local taxes. Your actual after-tax

6 VALUE FUNDS CEREDEX MID-CAP VALUE EQUITY FUND returns will depend on your tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their Fund shares through tax-advantaged arrangements, such as 401(k) plans or individual retirement accounts ( IRAs ). After-tax returns are shown for only the I Shares. After-tax returns for other share classes will vary. In some cases, average annual return after taxes on distributions and sale of fund shares is higher than the average annual return after taxes on distributions because of realized losses that would have been sustained upon the sale of fund shares immediately after the relevant periods. The calculations assume that an investor holds the shares in a taxable account, is in the actual historical highest individual federal marginal income tax bracket for each year and would have been able to immediately utilize the full realized loss to reduce his or her federal tax liability. However, actual individual tax results may vary and investors should consult their tax advisers regarding their personal tax situations. Investment Adviser and Subadviser RidgeWorth Investments is the Fund s investment adviser (the Adviser ). Ceredex Value Advisors LLC is the Fund s Subadviser. Tax Information The Fund s distributions are generally taxable as ordinary income, qualified dividend income, or capital gains unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an IRA, which may be taxed upon withdrawal. Payments to Broker-Dealers and Other Financial Intermediaries If you purchase shares of the Fund through a financial intermediary, such as a broker-dealer or investment adviser, the Fund, the Adviser or the Distributor may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other financial intermediary and your salesperson to recommend the Fund over another investment. Ask your financial intermediary or visit your financial intermediary s website for more information.
