• The “Floating Rate Loan Risk” contained in the “Principal Investment Risks” section of the Prospectus for the RidgeWorth Aggressive Growth Allocation Strategy, RidgeWorth Conservative Allocation Strategy, RidgeWorth Growth Allocation Strategy, RidgeWorth Moderate Allocation Strategy, RidgeWorth Seix Corporate Bond Fund, RidgeWorth Seix Floating Rate High Income Fund, RidgeWorth Seix High Income Fund, RidgeWorth Seix High Yield Fund, RidgeWorth Seix Limited Duration Fund and RidgeWorth Seix Total Return Bond Fund is replaced with the following:

Floating Rate Loan Risk: The value of the collateral securing a floating rate loan can decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. As a result, a floating rate loan may not be fully collateralized and can decline significantly in value. Floating rate loans generally are subject to contractual restrictions on resale. The liquidity of floating rate loans, including the volume and frequency of secondary market trading in such loans, varies significantly over time and among individual floating rate loans. During periods of infrequent trading, valuing a floating rate loan can be more difficult, and buying and selling a floating rate loan at an acceptable price can also be more difficult and delayed. Difficulty in selling a floating rate loan can result in a loss. In addition, floating rate loans generally are subject to extended settlement periods in excess of seven days, which may impair the Fund’s ability to sell or realize the full value of its loans in the event of a need to liquidate such loans. The Fund participates in a line of credit facility to assist with cash flow management and liquidity. Floating rate loans may not be considered securities and, therefore, the Fund may not have the protections of the federal securities laws with respect to its holdings of such loans.
