SEIX FLOATING RATE HIGH INCOME FUND

Summary Section

A Shares, C Shares, I Shares and IS Shares

Investment Objective

The Seix Floating Rate High Income Fund (the “Fund”) attempts to provide a high level of 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 15 of the Fund’s prospectus and Rights of Accumulation on page 59 of the Fund’s statement of additional information.

Shareholder Fees (fees paid directly from your investment)
	A Shares	C Shares	I Shares	IS Shares
Maximum Sales Charge (load) Imposed on Purchases (as a % of offering price)	2.50%	None	None	None
Maximum Deferred Sales Charge (load) (as a % of net asset value)	None	1.00%	None	None

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
	A Shares	C Shares	I Shares	IS Shares
Management Fees	0.40%	0.40%	0.40%	0.40%
Distribution (12b-1) Fees	0.30%	1.00%	None	None

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, if any, 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	$	340	$	530	$	736	$	1,330
C Shares	$	255	$	480	$	829	$	1,813
I Shares	$	62	$	195	$	340	$	762
IS Shares	$	53	$	167	$	291	$	653

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

	1 Year		3 Years		5 Years		10 Years
A Shares	$	340	$	530	$	736	$	1,330
C Shares	$	155	$	480	$	829	$	1,813
I Shares	$	62	$	195	$	340	$	762
IS Shares	$	53	$	167	$	291	$	653

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 47% 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 a combination of first- and second-lien senior floating rate loans and other floating rate debt securities.

These loans are loans made by banks and other large financial institutions to various companies and are senior in the borrowing companies’ capital structure. Coupon rates are generally floating, not fixed, and are tied to a benchmark lending rate, the most popular of which is the London Interbank Offered Rate (“LIBOR”) or are set at a specified floor, whichever is higher. LIBOR is based on rates that contributor banks in London charge each other for interbank deposits and is typically used to set coupon rates on floating rate debt securities. The interest rates of these floating rate debt securities vary

2 HIGH YIELD FUNDS

SEIX FLOATING RATE HIGH INCOME FUND

periodically based upon a benchmark indicator of prevailing interest rates.

The Fund invests all or substantially all of its assets in floating rate loans and debt securities that are rated below investment grade by the Merrill Composite Rating or Standard & Poor’s Financial Services LLC or in comparable unrated securities. The Fund may also invest up to 20% of its net assets in any combination of junior debt securities or securities with a lien on collateral lower than a senior claim on collateral, high yield fixed-rate bonds, investment grade fixed income debt obligations, asset-backed securities (such as special purpose trusts investing in bank loans), money market securities and repurchase agreements. The Fund may invest a portion of its assets in securities that are restricted as to resale.

In selecting investments for purchase and sale, the Fund’s Subadviser, Seix Investment Advisors LLC (“Seix” or the “Subadviser”), will emphasize securities which are within the segment of the high yield market it has targeted, which are securities rated below investment grade or unrated securities that the Subadviser believes are of comparable quality.

The Fund may invest up to 20% of its total assets in senior loans made to non-U.S. borrowers provided that no more than 5% of the portfolio’s loans are non-U.S. dollar denominated. The Fund may also engage in certain hedging transactions.

Some types of senior loans in which the Fund may invest require that an open loan for a specific amount be continually offered to a borrower. These types of senior loans are commonly referred to as revolvers. Because revolvers contractually obligate the lender (and therefore those with an interest in the loan) to fund the revolving portion of the loan at the borrower’s discretion, the Fund must have funds sufficient to cover its contractual obligation. Therefore the Fund will maintain, on a daily basis, high-quality, liquid assets in an amount at least equal in value to its contractual obligation to fulfill the revolving senior loan. The Fund will not encumber any assets that are otherwise encumbered. The Fund will limit its investments in such obligations to no more than 25% of the Fund’s total assets.

In addition, to implement its investment strategy, the Fund may buy or sell derivative instruments (such as swaps, including credit default swaps, futures, credit linked notes, options and warrants) 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 or credit risks. The Fund may count the value of certain derivatives with floating rate debt or high yield bond characteristics towards its policy to invest, under normal circumstances, at least 80% of its net assets in a combination of first- and second-lien senior floating rate loans and other floating rate debt securities.

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.

Below Investment Grade Securities Risk: Securities that are rated below investment grade (sometimes referred to as “junk bonds”, including those bonds rated lower than “BBB-” by Standard & Poor’s Financial Services LLC and Fitch, Inc. or “Baa3” by Moody’s Investors Service), or that are unrated but judged by the Subadviser to be of comparable quality at the time of purchase, involve greater risk of default and are more volatile than investment grade securities and are considered speculative. Below investment grade securities may also be less liquid than higher quality securities, and may cause income and principal losses for the Fund.

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.

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.

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

HIGH YIELD FUNDS 3

SEIX FLOATING RATE HIGH INCOME FUND

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, 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.

Foreign Currency Forward Contracts Risk: The technique of purchasing foreign currency forward contracts to obtain exposure to currencies or manage currency risk may not be effective. In addition, currency markets generally are not as regulated as securities markets.

Foreign Securities and Companies Risk: Foreign securities and dollar denominated securities of foreign issuers involve special risks such as economic or financial instability, lack of timely or reliable financial information and unfavorable political or legal developments. Foreign securities also involve risks such as currency fluctuations and delays in enforcement of rights. All of these risks are increased for investments in emerging markets.

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, the risk that the counterparty to the transaction will not meet its obligations, 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.

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.

Restricted Securities Risk: Certain debt securities may be restricted securities, which are not registered with the SEC and thus may not be sold publicly until registration has been made. Therefore, there is the absence of a public market and there is limited investor information.

Senior Loan Risk: Economic and other market events may reduce the demand for certain senior loans held by the Fund, which may adversely impact the net asset value of the Fund.

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.

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.

Tax Information

The Fund’s distributions are generally taxable as ordinary 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.

More Information About Principal Risks

Below Investment Grade Securities Risk

Securities that are rated below investment grade (commonly referred to as “junk bonds,” including those bonds rated lower than “BBB-” by Standard & Poor’s Financial Services LLC and Fitch, Inc. or “Baa3” by Moody’s Investors Service), or are unrated but judged by the Subadviser to be of comparable quality at the time of purchase, may be more volatile than higher-rated securities of similar maturity.

High yield securities may also be subject to greater levels of credit or default risk than higher-rated securities. The value of high yield securities can be adversely affected by overall economic conditions, such as an economic downturn or a period of rising interest rates, and high yield securities may be less liquid and more difficult to sell at an advantageous time or price or to value than higher-rated securities.

In particular, high yield securities are often issued by smaller, less creditworthy or highly leveraged (indebted) issuers, which are generally less able than more financially stable issuers to make scheduled payments of interest and principal.

Debt Securities Risk

The prices of a Fund’s fixed income securities respond to economic developments, particularly interest rate changes, as well as to perceptions about the creditworthiness of individual issuers, including governments. Generally, a Fund’s fixed income securities will decrease in value if interest rates rise and vice versa. Treasury Inflation Protected Securities (“TIPS”) can also exhibit such price movements as a result of changing inflation expectations and seasonal inflation patterns.

Long-term debt securities generally are more sensitive to changes in interest rates, usually making them more volatile than short-term debt securities and thereby increasing risk.

Debt securities are also subject to credit risk, which is the possibility than an issuer will fail to make timely payments of interest or principal or go bankrupt. The lower the ratings of such debt securities, the greater their risks. In addition, lower-rated securities have higher risk characteristics, and changes in economic conditions are likely to cause issuers of these securities to be unable to meet their obligations.

Debt securities are also subject to income risk, which is the possibility that falling interest rates will cause a Fund’s income to decline. Income risk is generally higher for short-term bonds.

An additional risk of debt securities is reinvestment risk, which is the possibility that a Fund may not be able to reinvest interest or dividends earned from an investment in such a way that they earn the same rate of return as the invested funds that generated them. For example, falling interest rates may prevent bond coupon payments from earning the same rate of return as the original bond.

Derivative Related Risks

Derivatives Risks. A derivative is a financial contract whose value adjusts in accordance with the value of one or more underlying assets, reference rates or indices. Derivatives (such as credit linked notes, futures, options, inverse floaters, swaps and warrants) may be used to attempt to achieve investment objectives or to offset certain investment risks. These positions may be established for hedging, substitution of a position in the underlying asset or for speculation purposes. Hedging involves making an investment (e.g., in a futures contract) to reduce the risk of adverse price movements in an already existing investment position. Because leveraging is inherent in derivatives, the use of derivatives also involves the risk of leveraging. Risks involved with hedging and leveraging activities include:

Ÿ The success of a hedging strategy may depend on an ability to predict movements in the prices of individual securities, fluctuations in markets, and movements in interest rates.

Ÿ A Fund may experience losses over certain market movements that exceed losses experienced by a Fund that does not use derivatives.

Ÿ There may be an imperfect or no correlation between the changes in market value of the securities held by a Fund and the prices of derivatives used to hedge those positions.

Ÿ There may not be a liquid secondary market for derivatives.

7

MORE INFORMATION

Ÿ Trading restrictions or limitations may be imposed by an exchange.

Ÿ Government regulations may restrict trading in derivatives.

Ÿ The other party to an agreement (e.g., options or swaps) may default.

Because premiums or totals paid or received on derivatives are small in relation to the market value of the underlying investments, buying and selling derivatives can be more speculative than investing directly in securities. In addition, many types of derivatives have limited investment lives and may expire or necessitate being sold at inopportune times.

The use of derivatives may cause a Fund to recognize higher amounts of short-term capital gains, which are generally taxed to shareholders at ordinary income tax rates.

Leverage may cause a 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 on the value of a Fund’s portfolio securities. To limit leveraging risk, a Fund observes asset segregation requirements to cover fully its future obligations. By setting aside assets equal only to its net obligations rather than the full notional amount under certain derivative instruments, a Fund will have the ability to employ leverage to a greater extent than if it were required to segregate assets equal to the full notional value of such derivative instruments.

Swap Risks. Each 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.

Floating Rate Loan Risk

Investments in floating rate loans are subject to interest rate risk although the risk is less because the interest rate of the loan adjusts periodically. Investments in floating rate loans are also subject to credit risk. Many floating rate loans are rated below investment grade or are unrated. Therefore, a Fund relies heavily on the analytical ability of the Fund’s Subadviser. Many floating rate loans share the same risks as high yield securities, although these risks are reduced when the floating rate loans are senior and secured as opposed to many high yield securities that are junior and unsecured. Floating rate loans are often subject to restrictions on resale which can result in reduced liquidity. The risk is greater for the Seix Floating Rate High Income Fund, because of its concentration in these types of instruments. Borrowers may repay principal faster than the scheduled due date which may result in a Fund replacing that loan with a lower-yielding security. Investment in loan participation interests may result in increased exposure to financial services sector risk. A loan may not be collateralized fully which may cause the loan to decline significantly in value.

Seix currently serves as collateral manager to six collateralized loan obligation (“CLO”) funds that invest in bank loans. In addition to the CLO funds, Seix serves as subadviser to an unaffiliated registered fund and as investment manager to three unregistered funds that may invest in bank loans. As a result of multiple investment-oriented and associated relationships, there exists a potential risk that the portfolio managers may favor other adviser and non-adviser contracted businesses over a Fund. Seix, the Subadviser to the Seix Floating Rate High Income Fund, has created and implemented additional policies and procedures designed to protect shareholders against such conflicts; however, there can be no absolute guarantee that a Fund will always participate in the same or similar investments or receive equal or better individual investment allocations at any given time.

Foreign Securities and Companies Risk

Investments in securities of foreign companies or governments can be more volatile than investments in U.S. companies or governments. Diplomatic, political or economic developments, including nationalization or appropriation, unique to a country or region will affect those markets and their issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets.

The value of securities denominated in foreign currencies, and of dividends from such securities, can change significantly when foreign currencies strengthen or weaken relative to the U.S. dollar. As a result, changes in the value of those currencies compared to the U.S. dollar may affect (positively or negatively) the value of a Fund’s investment. Foreign currency exchange rates may fluctuate significantly. They are determined by supply and demand in the foreign exchange markets, the relative merits of investments in different countries, actual or perceived

8

MORE INFORMATION

changes in interest rates, and other complex factors. Currency exchange rates also can be affected unpredictably by intervention (or the failure to intervene) by U.S. or foreign governments or central banks or by currency controls or political developments. Currency movements may happen separately from, and in response to, events that do not otherwise affect the value of the security in the issuer’s home country.

Foreign companies or governments generally are not subject to uniform accounting, auditing, and financial reporting standards comparable to those applicable to domestic U.S. companies or governments. Transaction costs are generally higher than those in the U.S. and expenses for custodial arrangements of foreign securities may be somewhat greater than typical expenses for custodial arrangements of similar U.S. securities. Some foreign governments levy withholding taxes against dividend and interest income. Although in some countries a portion of these taxes are recoverable, the non-recovered portion will reduce the income received from the securities comprising the portfolio.

All of these risks are increased for investments in emerging markets. Emerging markets may be more likely to experience political turmoil or rapid changes in market or economic conditions than more developed countries. In addition, the financial stability of issuers (including governments) in emerging market countries may be more precarious than in other countries. Emerging market countries are generally countries covered by the Bank of America Merrill Lynch Emerging Markets Diversified Corporate Index.

Restricted Securities Risk

Non-publicly traded securities may involve a high degree of business and financial risk and may result in substantial losses. These securities may be less liquid than publicly traded securities and the Fund may take longer to liquidate these positions than would be the case for publicly traded securities. Companies whose securities are not publicly traded may not be subject to the disclosure and other investor protection requirements applicable to companies whose securities are publicly traded. The Fund’s investments in restricted securities are subject to the risk that should the Fund desire to sell any of these securities when a ready buyer is not available at a price that is deemed to be representative of their value, the value of the Fund’s net assets could be adversely affected.

Senior Loan Risk

Portfolio transactions in loans may settle in as short as seven days but typically can take up to two or three weeks, and in some cases much longer. Unlike the securities markets, there is no central clearinghouse for loan trades, and the loan market has not established enforceable settlement standards or remedies for failure to settle. Credit risk is heightened for loans in which the Fund invests because companies that issue such loans may be leveraged and thus are more susceptible to the risks of interest deferral, default and/or bankruptcy.

U.S. Government-Related Risks

With respect to each Fund 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 its 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.

Risk Information Common to RidgeWorth Funds

Each Fund is a mutual fund. A mutual fund pools shareholders’ money and, using professional investment managers, invests it in securities.

Each Fund has its own investment objective and strategies for reaching that objective. The Adviser or Subadviser invests Fund assets in a way that it believes will help a Fund achieve its objective. Still, investing in each Fund involves risk and there is no guarantee that a Fund will achieve its objective. The Adviser’s or Subadviser’s judgments about the markets, the economy or companies may not anticipate actual market movements, economic conditions or company performance, and these judgments may affect the return on your investment. In fact, no matter how good a job the Adviser or Subadviser does, you could lose money on your investment in a Fund, just as you could with other investments. The value of your investment in a Fund is based on the market prices of the securities the Fund holds. These prices change daily due to economic and other events that affect particular companies and other issuers. These price movements, sometimes called volatility, may be greater or lesser depending on the types of securities a Fund owns and the markets in which they trade. The effect on a Fund of a change in the value of a single security will depend on how widely the Fund diversifies its holdings.

Each Fund’s investment objective may be changed without shareholder approval. Shareholders will be

given notice of any change in investment objective. Before investing, make sure that the Fund’s objective matches your own.

The Fund is not managed to achieve tax efficiency.

More Information About Indices

An index measures the market prices of a specific group of securities in a particular market or market sector. You cannot invest directly in an index. Unlike a mutual fund, an index does not have an investment adviser and does not pay any commissions or expenses. If an index had expenses, its performance would be lower.

The Credit Suisse Institutional Leveraged Loan Index is a sub-index of the Credit Suisse Leveraged Loan Index, which contains only institutional loan facilities priced above 90, excluding TL and TLA facilities and loans that are rated CC or C or are in default. It is designed to more closely reflect the investment criteria of institutional investors. The Index reflects reinvestment of all distributions and changes and market prices.

More Information About Fund Investments

This prospectus describes the Fund’s primary strategies, and the Fund will normally invest in the types of securities described in this prospectus. However, in addition to the investments and strategies described in this prospectus, each Fund also may invest in other securities, use other strategies and engage in other investment practices. These investments and strategies, as well as those described in this prospectus, are described in detail in the Funds’ Statement of Additional Information (“SAI”).

The investments and strategies described in this prospectus are those that the Funds use under normal conditions. During unusual economic or market conditions, or for temporary defensive or liquidity purposes, each Fund may invest up to 100% of its assets in cash, money market instruments, repurchase agreements and short-term obligations that would not ordinarily be consistent with a Fund’s objectives. Temporary defensive investments may limit a Fund’s ability to meet its investment objective. In addition, each Fund may shorten its average-weighted maturity to as little as 90 days. A Fund will do so only if the Adviser or its Subadviser believes that the risk of loss outweighs the opportunity for capital gains or higher income. Of course, a Fund cannot guarantee that it will achieve its investment objective.

Each Fund may invest in other mutual funds for cash management purposes. When a Fund invests in another mutual fund, in addition to directly bearing expenses associated with its own operations, it will bear a pro rata portion of the other mutual fund’s expenses.

Information About Portfolio Holdings

A description of the Fund’s policies and procedures with respect to the circumstances under which the Fund disclose its portfolio securities is available in the SAI. The Fund publicly discloses its portfolio holdings on its website at www.ridgeworth.com.

Management

The Board of Trustees (the “Board”) is responsible for the overall supervision and management of the business and affairs of the Fund. The Board supervises the Adviser and Subadvisers and establishes policies that the Adviser and Subadvisers must follow in their fund-related management activities. The day-to-day operations of the Fund are the responsibility of the officers and various service organizations retained by the Fund.

Investment Adviser

RidgeWorth Investments, located at 3333 Piedmont Road, Suite 1500, Atlanta, GA 30305 (“RidgeWorth” or the “Adviser”), serves as the investment adviser to the Fund. In addition to being an investment adviser registered with the Securities and Exchange Commission (the “SEC”), RidgeWorth is a money-management holding company with multiple style-focused investment boutiques. As of June 30, 2014, the Adviser had approximately $48.7 billion in assets under management. The Adviser is responsible for overseeing the Subadvisers to ensure compliance with each Fund’s investment policies and guidelines, and monitors each Subadviser’s adherence to its investment style. The Adviser pays the Subadviser out of the fees it receives from the Fund.

In addition, under a manager of managers arrangement, the Adviser may enter into or materially modify a subadvisory agreement with an unaffiliated subadviser, subject to approval by the Board and certain other conditions, without approval from the Fund’s

10

MANAGEMENT

shareholders. Any significant change in a Fund’s subadvisory arrangement will be communicated to shareholders.

The Adviser may use its affiliates as brokers for Fund transactions.

An investment adviser has a fiduciary obligation to its clients when the adviser has authority to vote their proxies. Under the current contractual agreement, the Adviser is authorized to vote proxies on behalf of each Fund. Information regarding the Adviser’s, and thus each Fund’s, Proxy Voting Policies and Procedures is provided in the SAI. A copy of the Adviser’s Proxy Voting Policies and Procedures may be obtained by contacting the Funds at 1-888-784-3863 or by visiting www.ridgeworth.com.

For the fiscal year ended March 31, 2014, the Fund paid the Adviser advisory fees (after waivers) of 0.40% of the Fund’s average daily net assets.

The Adviser and each Subadviser have contractually agreed to waive fees and reimburse expenses until at least August 1, 2015, in order to keep total annual operating expenses of the Fund from exceeding the applicable expense cap shown. If at any point before August 1, 2017, total annual operating expenses are less than the expense cap, the Adviser may retain the difference to recapture any of the prior waivers or reimbursements.

Fund	Share Class		Expense Limitation
Seix Floating Rate High Income		A		1.00%
		C		1.60%
		I		0.70%
		IS		0.60%

The following breakpoints are used in computing the advisory fee:

Average Daily Net Assets	Discount From Full Fee
First $500 million	None —Full Fee
Next $500 million	5%
Next $4 billion	10%
Over $5 billion	15%

Based on average daily net assets as of March 31, 2014, the asset levels of the Fund had reached a breakpoint in the advisory fee.* Had the Fund asset levels been lower, the Adviser may have been entitled to receive maximum advisory fees of 0.45%

* Fund expenses in the “Annual Fund Operating Expenses” tables shown earlier in this prospectus reflect the advisory breakpoints.

A discussion regarding the basis for the Board’s approval of the continuance of the investment advisory agreement with the Adviser appears in the Fund’s annual report to shareholders for the period ended March 31, 2014.

Investment Subadvisers

The Subadviser is responsible for managing the portfolios of the Fund on a day-to-day basis and selecting the specific securities to buy, sell and hold for the Fund under the supervision of the Adviser and the Board. A discussion regarding the basis for the Board’s approval of the continuance of the investment subadvisory agreements appears in the Fund’s annual report to shareholders for the period ended March 31, 2014.

Information about the Subadviser and the individual portfolio managers of the Fund is discussed below. The SAI provides additional information regarding the portfolio managers’ compensation, other accounts managed by the portfolio managers, potential conflicts of interest and the portfolio managers’ ownership of securities in the Fund.

Purchasing, Selling and Exchanging Fund Shares

This section tells you how to purchase, sell (sometimes called “redeem”) and exchange A Shares, C Shares, I Shares and IS Shares of the Funds. Investors purchasing or selling shares through a pension or 401(k) plan should also refer to their Plan documents.

Participants in retirement plans must contact their Employee Benefits Office or their Plan’s Administrator for information regarding the purchase, redemption or exchange of shares. Plans may require separate documentation and the plan’s policies and procedures may be different than those described in this prospectus. Participants should contact their employee benefits office or plan administrator for questions about their specific accounts.

If your I Shares or IS Shares are held in a retirement plan account, the rules and procedures you must follow as a plan participant regarding the purchase, redemption or exchange of I Shares or IS Shares may be different from those described in this prospectus. Review the information you have about your retirement plan.

How to Purchase Fund Shares

Purchasing A Shares and C Shares

You may purchase A Shares and C Shares of the Funds through financial institutions or intermediaries that are authorized to place transactions in Fund shares for their customers. Please contact your financial institution or intermediary directly and follow its procedures for Fund share transactions. Your financial institution or intermediary may charge a fee for its services, in addition to the fees charged by a Fund. You will also, generally, have to address your correspondence or questions regarding a Fund to your financial institution or intermediary.

Your investment professional can assist you in opening a brokerage account that will be used for purchasing shares of RidgeWorth Funds.

Shareholders who purchase shares directly from the Funds may purchase additional Fund shares by:

Ÿ Mail

Ÿ Telephone (1-888-784-3863)

Ÿ Wire

Ÿ Fax (1-800-451-8377)

Ÿ Automated Clearing House (“ACH”)

The Funds do not accept cash, credit card checks, third-party checks, travelers’ checks, money orders, bank starter checks, or checks drawn in a foreign currency, as payment for Fund shares.

If you pay with a check or ACH transfer that does not clear or if your payment is not received in a timely manner, your purchase may be canceled. You will be responsible for any losses or expenses incurred by the Funds or its transfer agent, and the Funds can redeem shares you own in any of the Funds or in another identically registered RidgeWorth Funds account as reimbursement.

Purchasing I Shares

The Funds offer I Shares to financial institutions and intermediaries for their own accounts or for the accounts of customers for whom they act as fiduciary, agent, investment adviser, or custodian. Financial intermediaries include brokers, dealers, banks (including bank trust departments), trust companies, registered investment advisers, financial planners, retirement plan administrators, insurance companies, and any other institution having a service, administration, or any similar arrangement with the

12

PURCHASING, SELLING AND EXCHANGING FUND SHARES

Funds or their service providers. These accounts primarily consist of:

Ÿ assets of a bona fide trust,

Ÿ assets of a business entity possessing a tax identification number,

Ÿ assets of an employee benefit plan,

Ÿ assets held within select fee-based programs, or

Ÿ assets held within certain non-discretionary intermediary no-load platforms.

Employee benefit plans generally include profit sharing, 401(k) and 403(b) plans. Employee benefit plans generally do not include IRAs; SIMPLE, SEP, SARSEP plans; plans covering self-employed individuals and their employees; or health savings accounts unless you, as a customer of a financial institution or intermediary, meet the Funds’ established criteria as described above.

As a result, you, as a customer of a financial institution or intermediary, may, under certain circumstances that meet the Funds’ established criteria, be able to purchase I Shares through accounts made with select financial institutions or intermediaries. I Shares will be held of record by (in the name of) your financial institution or intermediary. Depending upon the terms of your account, you may have, or be given, the right to vote your I Shares. Financial institutions or intermediaries may impose eligibility requirements for each of their clients or customers investing in the Funds, including investment minimum requirements, which may differ from those imposed by the Funds. Please contact your financial institution or intermediary for complete details for purchasing I Shares.

I Shares may also be purchased directly from the Funds by officers, directors or trustees, and employees and their immediate families (strictly limited to current spouses/domestic partners and dependent children) of RidgeWorth Funds, the Adviser and Subadvisers to the RidgeWorth Funds.

Validation of current employment/service will be required upon establishment of the account. The Funds, in their sole discretion, may determine if an applicant qualifies for this program.

Purchasing IS Shares

IS Shares are offered to the following investors, provided that these investors do not require the Fund or an affiliate of the Fund (including the Fund’s Adviser and any affiliate of the Adviser) to make, and the Fund or affiliate does not pay, any type of servicing, administrative, or revenue sharing payments with respect to IS Shares:

Ÿ qualified retirement plans, including, but not limited to, 401(k) plans, 457 plans, employer sponsored 403(b) plans, defined benefit plans and other accounts or plans whereby IS Shares are held on the books of the Fund through omnibus accounts (either at the plan level or the level of the plan administrator);

Ÿ bank and trust companies;

Ÿ insurance companies;

Ÿ registered investment companies;

Ÿ non-qualified deferred compensation plans; and

Ÿ other institutional investors that:

– meet a $2,500,000 minimum initial investment requirement; and

– hold interests in the Fund through a single plan level account held directly through the Fund and not traded through an intermediary.

Such availability will be subject to management’s determination of the eligibility of investment in IS Shares.

The $2,500,000 minimum initial investment amount may be waived subject to management’s discretion, and/or purchased by or through:

Ÿ certain registered open-end investment companies whose shares are distributed by the Distributor;

Ÿ accounts held by, or for the benefit of, an affiliate of the Fund; or

Ÿ investments made in connection with certain reorganizations as approved by the Adviser.

If the value of your account falls below the minimum initial investment requirements for IS Shares as a result of share redemptions or you no longer meet one of the waiver criteria set forth above, your account may be subject to involuntary conversion or involuntary redemption, as applicable. You will be notified prior to any such conversions or redemptions.

In-Kind Purchases — A Shares, C Shares, I Shares and IS Shares

Payment for shares of a Fund may, at the discretion of the Adviser, be made in the form of securities that are permissible investments for such Fund. In connection with an in-kind securities payment, a Fund will require, among other things, that the securities: (a) meet the investment objectives and policies of the Fund; (b) are acquired for investment and not for resale; (c) are liquid

13

PURCHASING, SELLING AND EXCHANGING FUND SHARES

securities that are not restricted as to transfer either by law or liquidity of markets; (d) have a value that is readily ascertainable (e.g., by a listing on a nationally recognized securities exchange); and (e) are valued on the day of purchase in accordance with the pricing methods used by the Fund. For further information about this form of payment, please call 1-888-784-3863.

When Can You Purchase Shares? — A Shares, C Shares, I Shares and IS Shares

The Funds are open for business on days when the New York Stock Exchange (the “NYSE”) is open for regular trading (a “Business Day”). The RidgeWorth Funds reserve the right to open one or more Funds on days that the principal bond markets (as recommended by the Securities Industry and Financial Markets Association) are open, even if the NYSE is closed. Each Fund calculates its net asset value per share (“NAV”) once each Business Day at the close of regular trading on the NYSE (normally 4:00 p.m. Eastern Time).

If a Fund or its authorized agent receives your purchase or redemption request in proper form before 4:00 p.m. Eastern Time, your transaction will be priced at that Business Day’s NAV. If your request is received after 4:00 p.m. Eastern Time, it will be priced at the next Business Day’s NAV.

The time at which transactions and shares are priced and the time until which orders are accepted may be changed if the NYSE closes early or if the principal bond markets close early on days when the NYSE is closed. For those Funds that open on days when the NYSE is closed, these times will be the time the principal bond markets close.

The Funds will not accept orders that request a particular day or price for the transaction or any other special conditions.

You may be required to transmit your purchase, sale and exchange orders to your financial institutions or intermediaries at an earlier time for your transaction to become effective that day. This allows your financial institution or intermediary time to process your order and transmit it to the transfer agent in time to meet the above stated Fund cut-off times. For more information about how to purchase, sell or exchange Fund shares, including your financial institution’s or intermediary’s internal order entry cut-off times, please contact your financial institution or intermediary directly.

A Fund may reject any purchase order.

How the Funds Calculate NAV — A Shares, C Shares, I Shares and IS Shares

The NAV is calculated by adding the total value of a Fund’s investments and other assets, subtracting its liabilities, and then dividing that figure by the number of outstanding shares of the Fund.

In calculating the NAV, each Fund generally values its investment portfolio at market price. If market prices are not readily available, or a Fund reasonably believes that market prices or amortized cost valuation methods are unreliable, such as in the case of a security value that has been materially affected by events occurring after the relevant market closes, a Fund is required to price those securities at fair value as determined in good faith using methods approved by the Board. A Fund’s determination of a security’s fair value price often involves the consideration of a number of subjective factors, and is, therefore, subject to the unavoidable risk that the value that a Fund assigns to a security may be higher or lower than the security’s value would be if a reliable market quotation for the security was readily available.

With respect to non-U.S. securities held by a Fund, the Fund may take factors influencing specific markets or issues into consideration in determining the fair value of a non-U.S. security. International securities markets may be open on days when the U.S. markets are closed. In such cases, the value of any international securities owned by a Fund may be significantly affected on days when investors cannot buy or sell shares. In addition, due to the difference in times between the close of the international markets and the time a Fund prices its shares, the value the Fund assigns to securities generally will not be the same as the primary markets or exchanges. In determining fair value prices, a Fund may consider the performance of securities on their primary exchanges, foreign currency appreciation/depreciation, securities market movements in the U.S., or other relevant information as related to the securities.

When valuing fixed income securities with remaining maturities of more than 60 days, the Funds use the value of the security provided by pricing services. The values provided by a pricing service may be based upon market quotations for the same security, securities expected to trade in a similar manner, or a pricing matrix. When valuing fixed income securities with remaining maturities of 60 days or less, the Funds use the security’s amortized cost. Amortized cost and the use of a pricing matrix in valuing fixed income securities are forms of fair value pricing. Fair value prices may be determined in good faith using methods approved by the Board.

PURCHASING, SELLING AND EXCHANGING FUND SHARES

Minimum/Maximum Purchases — A Shares, C Shares, I Shares and IS Shares

To purchase shares for the first time, you must invest in any Fund at least:

Class	Dollar Amount
A Shares	$2,000
C Shares	$5,000 ($2,000 for IRAs or other tax-advantaged accounts)
I Shares	No minimum
IS Shares	$2,500,000

Your subsequent investments must be made in amounts of at least $1,000. The Funds reserve the right to waive and/or reduce the minimum investment amounts for certain A and C Share purchases.

For investors who qualify to purchase I Shares, there are no minimum or maximum requirements for initial or subsequent purchases.

Officers, directors or trustees, and employees and their immediate families (strictly limited to current spouses/domestic partners and dependent children) of the Funds, Adviser and the Subadvisers may also purchase I Shares. There is no minimum investment.

Systematic Investment Plan — A Shares and C Shares

If you have a checking or savings account with a bank, you may purchase A Shares and C Shares automatically through regular deductions from your bank account. With a $500 minimum initial investment, you may begin regularly-scheduled investments of $50 or more once or twice a month. If you are buying C Shares, you should plan on investing at least $5,000 per Fund during the first two years. The Funds may close your account if you do not meet this minimum investment requirement at the end of two years. Shareholders should contact their financial intermediaries for more information on how to take advantage of this feature.

Customer Identification

Foreign Investors

To purchase A Shares, C Shares and IS Shares of the Funds, you must be a U.S. citizen, a U.S. resident alien, or a U.S. entity, with a U.S. tax identification number, and reside in the U.S. or its territories (which includes U.S. military APO or FPO addresses). If you owned shares on July 31, 2006, you may keep your account open even if you do not reside in the U.S. or its territories, but you may not make additional purchases or exchanges.

The Funds do not generally accept investments in I Shares by non-U.S. citizens or entities. Investors in I Shares generally must reside in the U.S. or its territories (which includes U.S. military APO or FPO addresses) and have a U.S. tax identification number.

Customer Identification and Verification

To help the government fight the funding of terrorism and money laundering activities, U.S. federal law requires all financial institutions to obtain, verify, and record information that identifies each person who opens an account.

When you open an account, you will be asked to provide your name, residential street address, date of birth, and Social Security Number or tax identification number. You may also be asked for other information that will allow us to identify you. Entities are also required to provide additional documentation. This information will be verified to ensure the identity of all persons opening a mutual fund account.

In certain instances, the Funds are required to collect documents to fulfill their legal obligation. Documents provided in connection with your application will be used solely to establish and verify a customer’s identity.

The Funds are required by law to reject your new account application if the required identifying information is not provided. Attempts to collect the missing information required on the application will be performed by either contacting you or, if applicable, your broker. If this information is unable to be obtained within a timeframe established at the sole discretion of the Funds, your application will be rejected.

Upon receipt of your application in proper form (or upon receipt of all identifying information required on the application), your investment will be accepted and your order will be processed at the NAV next determined.

However, the Funds reserve the right to close your account at the then-current day’s price if the Funds are unable to verify your identity. Attempts to verify your identity will be performed within a timeframe established at the sole discretion of the Funds. If the Funds are unable to verify your identity, the Funds reserve the right to liquidate your account at the then-current day’s price and remit proceeds to you via check. The Funds reserve the further right to hold your proceeds until your original check clears the bank. In such an instance, you may be subject to a gain or loss on Fund shares and will be subject to corresponding tax implications.

Anti-Money Laundering Program

Customer identification and verification is part of the Funds’ overall obligation to deter money laundering

15

PURCHASING, SELLING AND EXCHANGING FUND SHARES

under U.S. federal law. The Funds have adopted an anti-money laundering compliance program designed to prevent the Funds from being used for money laundering or the financing of terrorist activities. In this regard, the Funds reserve the right to (i) refuse, cancel or rescind any purchase or exchange order, (ii) freeze any account and/or suspend account services, or (iii) involuntarily redeem your account in cases of threatening conduct or suspected fraudulent or illegal activity. These actions will be taken when, at the sole discretion of Fund management, they are deemed to be in the best interest of the Funds or in cases when the Funds are requested or compelled to do so by governmental or law enforcement authority.

Sales Charges — A Shares and C Shares

Front-End Sales Charges — A Shares

The offering price of A Shares is the NAV next calculated after a Fund receives your request in proper form, plus the front-end sales charge.

The amount of any front-end sales charge included in your offering price varies, depending on the amount of your investment.

For the Funds listed below, the immediately following table applies:

Seix Floating Rate High Income Fund

If Your Investment is:	Your Sales Charge as a Percentage of Offering Price*		Your Sales Charge as a Percentage of Your Net Investment
Less than $50,000		2.50%		2.56%
$50,000 but less than $100,000		2.25%		2.30%
$100,000 but less than $250,000		2.00%		2.04%
$250,000 but less than $500,000		1.75%		1.78%
$500,000 but less than $1,000,000		1.50%		1.52%
$1,000,000 and over		None		None

* The Distributor may pay a percentage of the offering price as a commission to broker-dealers. While investments over $1,000,000 are not subject to a front-end sales charge, the Distributor may pay dealer commissions ranging from 0.25% to 0.50%.

Investments of $1,000,000 or more. You do not pay an initial sales charge when you buy $1,000,000 or more of A Shares in either a single investment or through our rights of accumulation, letter of intent, or combined purchase/quantity discount programs. However, you will pay a deferred sales charge of 0.50% if you redeem any of these A Shares within two years of purchase. The deferred sales charge may be waived from time to time for certain broker-dealers that waive payment of compensation to them. The deferred sales charge is calculated based on the lesser of (i) the NAV of the shares at the time of purchase or (ii) the NAV of the shares next calculated after the Fund receives your redemption request. The deferred sales charge does not apply to shares you purchase through reinvestment of dividends or capital gains distributions.

Waiver of Front-End Sales Charge — A Shares

The front-end sales charge may be waived on A Shares purchased:

Ÿ through reinvestment of dividends and distributions;

Ÿ through an account managed by an affiliate of the Adviser;

Ÿ by persons repurchasing shares they redeemed within the last 180 days (see “Repurchase of A Shares”);

Ÿ by employees, and members of their immediate family (spouse/domestic partner, mother, father, mother-in-law, father-in-law, and children, including step-children, under the age of 21 years), of the Adviser and its affiliates;

Ÿ by persons investing an amount less than or equal to the value of an account distribution when an account for which a bank affiliated with the Adviser acted in a fiduciary, administrative, custodial or investment advisory capacity is closed;

Ÿ through financial intermediaries or institutions; retirement plans, plan administrators or record-keepers; asset allocation, or wrap programs or self-directed investment brokerage accounts; that, under the terms of their respective agreements with the Distributor or otherwise, agree to either (i) not charge the front-end sales charge, or (ii) do not receive compensation derived from the front-end sales charge, but may or may not charge a transaction fee to their customers; or

Ÿ by Trustees and officers of the RidgeWorth Funds.

Repurchase of A Shares

You may repurchase any amount of A Shares of any Fund at the NAV (without the normal front-end sales charge), up to the limit of the value of any amount of A Shares (other than those which were purchased with reinvested dividends and distributions) that you redeemed within the past 180 days. In effect, this allows you to reacquire shares that you may have had to

16

PURCHASING, SELLING AND EXCHANGING FUND SHARES

redeem, without re-paying the front-end sales charge. Such repurchases may be subject to special tax rules. See the “Taxes” section of the SAI for more information. To exercise this privilege, the Funds must receive your purchase order within 180 days of your redemption. In addition, you must notify the Fund when you send in your purchase order that you are repurchasing shares.

Reduced Sales Charges — A Shares

Rights of Accumulation. You may take into account your accumulated holdings in all share classes of RidgeWorth Funds to determine the initial sales charge you pay on each purchase of A Shares. In calculating the appropriate sales charge rate, this right allows you to add the market value (at the close of business on the day of the current purchase) of your existing holdings in any class of shares to the amount of A Shares you are currently purchasing. The Funds may amend or terminate this right at any time. Please see the Funds’ SAI for details.

Letter of Intent. A Letter of Intent allows you to purchase A Shares over a 13-month period and receive the same sales charge as if you had purchased all the shares at the same time. The Funds will hold a certain portion of your investment in escrow until you fulfill your commitment. Please see the SAI for details.

Combined Purchase/Quantity Discount Privilege. When calculating the appropriate sales charge rate, the Funds will combine same day purchases of shares of any class made by you, your spouse/domestic partner and your minor children (under age 21). This combination also applies to A Shares you purchase with a Letter of Intent.

You can also obtain information about sales charges, rights of accumulation and letters of intent on the Funds’ website at www.ridgeworth.com.

Contingent Deferred Sales Charges (“CDSC”) — C Shares

You do not pay a sales charge when you purchase C Shares. The offering price of C Shares is simply the next calculated NAV. But, if you sell your shares within the first year after your purchase, you will pay a CDSC equal to 1% of either (i) the NAV of the shares at the time of purchase, or (ii) the NAV of the shares next calculated after the Funds receive your sale request, whichever is less. The Funds will use the first-in, first-out (FIFO) method to determine the holding period. You never pay a CDSC on any increase in your investment above the initial offering price. The CDSC does not apply to shares you purchase through reinvestment of dividends or distributions or to exchanges of C Shares of one Fund for C Shares of another Fund.

Waiver of CDSC

The CDSC will be waived if you sell your C Shares for the following reasons:

Ÿ Death or Post-purchase Disablement (as defined in Section 72(m)(7) of the Internal Revenue Code Code of 1986, as amended (the “Internal Revenue Code”))

– You are shareholder/joint shareholder or participant/beneficiary of certain retirement plans;

– You die or become disabled after the account is opened;

– Redemption must be made within 1 year of such death/disability;

– The Funds must be notified in writing of such death/disability at time of redemption request; and

– The Funds must be provided with satisfactory evidence of death (death certificate) or disability (doctor’s certificate specifically referencing disability as defined in 72(m)(7) of the Internal Revenue Code).

Ÿ Shares purchased through dividend and capital gains reinvestment.

Ÿ Participation in the Systematic Withdrawal Plan described below:

– Withdrawal not to exceed 10% of the current balance of a Fund in a 12 month period. The 10% amount will be calculated as of the date of the initial Systematic Withdrawal Plan and recalculated annually on the 12 month anniversary date. Shares purchased through dividend or capital gains reinvestment, although not subject to the CDSC, will be included in calculating the account value and 10% limitation amount.

– If the total of all Fund account withdrawals (Systematic Withdrawal Plan or otherwise) exceeds the 10% limit within the 12 month period following the initial calculation date, the entire Systematic Withdrawal Plan for the period will be subject to the applicable sales charge. In the initial year of a Systematic Withdrawal Plan, the withdrawal limitation period shall begin 12 months before the initial Systematic Withdrawal Plan payment.

– To qualify for the CDSC waiver under the Systematic Withdrawal Plan, a Fund account must have a minimum of $25,000 at Systematic Withdrawal Plan inception and must also reinvest dividends and capital gains distributions.

17

PURCHASING, SELLING AND EXCHANGING FUND SHARES

Ÿ Required mandatory minimum withdrawals made after 70  ¹⁄₂ under any retirement plan qualified under Sections 401, 408 or 403(b) of the Internal Revenue Code or resulting from the tax free return of an excess distribution to an IRA. Satisfactory qualified plan documentation to support any waiver includes employer letter (separation from services) and plan administrator certificate (certain distributions under plan requirements).

Ÿ Permitted exchanges of shares, except if shares acquired by exchange are then redeemed within the period during which a CDSC would apply to the initial shares purchased.

Ÿ Exchanges in connection with plans of Fund reorganizations such as mergers and acquisitions.

To take advantage of any of these waivers, you must qualify in advance. To see if you qualify, please call your investment professional or other investment representative. These waivers are subject to change or elimination at any time at the discretion of the Funds.

The C Shares CDSC will be waived for certain retirement plan providers that have entered into administrative agreements with the Funds. Please see the SAI for more information on this program.

The CDSC may also be waived from time to time for certain broker-dealers that waive payment of compensation to them.

Offering Price of Fund Shares — A Shares, C Shares, I Shares and IS Shares

The offering price of A Shares is the NAV next calculated after the transfer agent receives your request, in proper form, plus any front-end sales charge. The offering price of C Shares, I Shares and IS Shares is simply the next calculated NAV.

You can also obtain information about sales charges, rights of accumulation and letters of intent on the Funds’ website at www.ridgeworth.com.

How to Sell Your Fund Shares

Selling A Shares and C Shares

Your broker, financial institution or intermediary may charge a fee for its services, in addition to the fees charged by the Funds.

Shareholders who purchased shares directly from the Funds may sell their Fund shares by:

Ÿ Mail

Ÿ Telephone (1-888-784-3863)

Ÿ Wire

Ÿ Fax (1-800-451-8377)

Holders of I Shares and IS Shares may sell shares by following the procedures established when they opened their account or accounts with the Funds or with their financial institution or intermediary. The sale price of each share will be the next NAV determined after the Funds receive your request in proper form.

Signature Authentication — A Shares, C Shares, I Shares and IS Shares

This section describes the Funds’ Medallion Signature Guarantee and Signature Validation Program (SVP) policies. If you purchased your shares through a financial institution or intermediary, the below policies may not apply. Please contact your financial institution or intermediary for additional information on their signature authentication policy.

For certain financial and non-financial transactions, the Funds require proof that your signature is authentic and you have the authority to provide the instruction(s) contained in the request. This verification can be provided by either a Medallion Signature Guarantee Stamp for financial transactions or an SVP Stamp for non-financial transactions.

Both types of stamps can be obtained from a financial institution such as a domestic bank, trust company, broker/dealer, clearing agency, savings association, or other financial institution that participates in the Medallion Signature Guarantee Program or SVP. Please visit www.ridgeworth.com for a Letter of Instruction Form that you can provide to your financial institution to obtain the appropriate stamp. Please note a notarized signature is not an acceptable substitute for a Medallion Signature Guarantee or an SVP Stamp. The Funds reserve the right, at their sole discretion, to waive such requirements for a specific request.

PURCHASING, SELLING AND EXCHANGING FUND SHARES

Financial Transactions

An original document containing a Medallion Signature Guarantee is required for certain types of financial transactions. Examples include:

Ÿ Redemption proceeds payable or sent to any person, address, or bank account other than the one currently on record.

Ÿ Redemption requests sent to an address or bank account of record that has been changed within the last 30 days.

Ÿ Registration or ownership changes to your account. Ownership changes may include but are not limited to, certain types of transfers, gifting shares, beneficial inheritance, and loan collateral agreements.

Non-Financial Transactions

For certain non-financial transactions, the Funds will accept an original document containing an SVP Stamp. In the event an SVP Stamp is not used by the financial institution, you should request that it use its Medallion Signature Guarantee in lieu of the SVP Stamp. Examples include:

Ÿ Changing your name.

Ÿ Requests to add or change banking information that the Funds have on file.

Ÿ Updates to authorized signers on your account.

Sale Price of Fund Shares — A Shares, C Shares, I Shares and IS Shares

The sale price of each share will be the next NAV determined after the Funds receive your request, in proper form, less, in the case of C Shares, any applicable CDSC.

Systematic Withdrawal Plan — A Shares and C Shares

If you have at least $10,000 in your account, you may use the Systematic Withdrawal Plan. Under the plan you may arrange monthly, quarterly, semi-annual or annual automatic withdrawals of at least $50 from any Fund. The proceeds of each withdrawal will be mailed to you by check or, if you have a checking or savings account with a bank, may be electronically transferred to your account. Please check with your bank. Withdrawals under the Systematic Withdrawal Plan may be subject to a CDSC unless they meet the requirements described above under “Waiver of the CDSC.” Shareholders should contact their financial intermediaries for more information on how to take advantage of this feature.

Receiving Your Money — A Shares, C Shares, I Shares and IS Shares

Normally, the Funds will send your sale proceeds within five Business Days after the Funds receive your request, but a Fund may take up to seven days to pay the sale proceeds if making immediate payments would adversely affect the Fund (for example, to allow the Fund to raise capital in the case of a large redemption). Your sale proceeds can be wired to your bank account (subject to a fee) or sent to you by check. If you recently purchased your shares by check or through ACH, redemption proceeds may not be available until your funds have cleared (which may take up to 10 calendar days from your date of purchase).

Each Fund tries to manage large redemptions of positions in the Fund. However, a large redemption by a shareholder holding a significant investment in a Fund may have an adverse impact on the remaining shareholders in the Fund. For example, such a redemption may cause the Fund to (i) utilize outside sources of liquidity, which may be more costly, or (ii) liquidate securities that otherwise would not have been sold, potentially impacting the Fund’s performance and generating capital gains distributions.

Redemptions In-Kind — A Shares, C Shares, I Shares and IS Shares

The Funds generally pay redemption proceeds in cash. However, under unusual conditions that make the payment of cash unwise (and for the protection of the Funds’ remaining shareholders), the Funds might pay all or part of your redemption proceeds in liquid securities with a market value equal to the redemption price (redemption in kind). It is highly unlikely that your shares would ever be redeemed in kind, but if they were you would probably have to pay transaction costs to sell the securities distributed to you, as well as taxes on any capital gains recognized in the redemption or in the sale of the securities distributed to you.

Involuntary Sales of Your Shares — A Shares, C Shares, I Shares and IS Shares

If your account balance drops below the required minimum as a result of redemptions you may be required to sell your shares. The account balance minimums are:

Class	Dollar Amount
A Shares	$2,000
C Shares	$5,000 ($2,000 for IRAs or other tax-advantaged accounts)
I Shares	No minimums
IS Shares	$2,500,000

19

PURCHASING, SELLING AND EXCHANGING FUND SHARES

The Funds will always give you at least 60 days written notice to give you time to add to your account and avoid the sale of your shares.

Shareholders should contact their financial intermediary regarding minimum investment requirements.

Suspension of Your Right to Sell Your Shares — A Shares, C Shares, I Shares and IS Shares

A Fund may suspend your right to sell your shares if the NYSE restricts trading, the SEC declares an emergency or for other reasons approved by the SEC. More information about this is in the Funds’ SAI.

Exchanging or Converting Your Shares

Exchanging Your Shares — A Shares, C Shares, I Shares and IS Shares

You may exchange your Fund shares for the same class of shares of any other RidgeWorth Fund. Your sales price and purchase price will be based on the NAV next calculated after the Funds receive your exchange request in proper form.

Cross Class Conversions

You may convert your shares for shares of a different class of the same Fund based on the NAV of each class next calculated after the Fund receives your exchange request in proper form. If you have held your current shares for less than one year, your financial intermediary may assess any applicable CDSC on your shares when you make the conversion.

Instructions for Exchanging and Converting Shares

You may exchange or convert your shares on any Business Day by contacting the Funds at 1-888-784-3863 or the financial institution or intermediary through which your shares are held.

Exchanges into the State Street Liquid Reserves Fund — Investment Class

At any time, you may exchange your A, C or I Shares of a Fund for shares of the State Street Institutional Liquid Reserves Fund–Investment Class. Further, qualifying shares of the State Street Institutional Liquid Reserves Fund–Investment Class may be exchanged for A, C or I Shares of any Fund. You should read the State Street Institutional Liquid Reserves Fund–Investment Class prospectus prior to investing in that mutual fund. You can obtain a prospectus State Street Institutional Liquid Reserves Fund–Investment Class by calling 1-888-784-3863 or by visiting our website at www.ridgeworth.com. Qualifying exchanges between the Funds’ A and C Shares and the State Street Institutional Liquid Reserves Fund–Investment Class are eligible for exchange into the Funds’ A and/or C Shares without the imposition of the applicable front-end sales charge and/or CDSC.

If you purchased shares though a financial institution or intermediary please contact your financial institution or intermediary regarding the availability of this exchange privilege.

Notes on Exchanges and Conversions

You must meet investor eligibility requirements applicable to the share class into which you are exchanging. The Funds may accept investments of smaller amounts at its discretion. The Funds will treat any cross class conversion between classes of shares of the same Fund as a tax-free event. An exchange between the same classes of shares of different Funds generally is treated as a taxable event.

For the purpose of computing the CDSC applicable to C Shares, the length of time you have owned your shares will be measured from the original date of purchase and will not be affected by any exchange.

The exchange privilege is not intended as a vehicle for short-term trading. Excessive exchange activity may interfere with Fund management and may have an adverse effect on all shareholders. In order to limit excessive exchange activity and in other circumstances where it is in the best interests of a Fund, all Funds reserve the right to revise or terminate the exchange privilege, limit the amount or number of exchanges or reject any exchange or restrict or refuse purchases if (i) a Fund or its manager(s) believes the Fund would be harmed or unable to invest effectively, or (ii) a Fund receives or anticipates orders that may dramatically affect the Fund as outlined under “Market Timing Policies and Procedures” below.

If you recently purchased shares by check or through ACH, you may not be able to exchange your shares until your funds have cleared (which may take up to 10 calendar days from your date of purchase).

Systematic Exchange Plan — A Shares and C Shares

For investors who qualify, a systematic exchange feature may be added to your account. Shareholders should contact their financial intermediary for more information about how to take advantage of this feature and the minimum investment requirements.

AND PROCEDURES

Telephone Transactions — A Shares, C Shares, I Shares and IS Shares

Purchasing, selling and exchanging Fund shares over the telephone is extremely convenient, but not without risk. Although the Funds have certain safeguards and procedures to confirm the identity of callers and the authenticity of instructions, the Funds are not responsible for any losses or costs incurred by following telephone instructions the Funds reasonably believe to be genuine. If you or your financial institution or intermediary transact with the Funds over the telephone, you will generally bear the risk of any loss. The Funds reserve the right to modify, suspend or terminate telephone transaction privileges at any time.

To redeem shares by telephone:

Ÿ redemption checks must be made payable to the registered shareholder; and

Ÿ redemption checks must be mailed to an address or wired to a bank account of record that has been associated with the shareholder account for at least 15 calendar days.

Market Timing Policies and Procedures

The Funds are intended for long-term investment purposes only and discourage shareholders from engaging in “market timing” or other types of excessive short-term trading. This frequent trading into and out of the Funds may present risks to the Funds’ long-term shareholders, all of which could adversely affect shareholder returns. The risks posed by frequent trading include interfering with the efficient implementation of the Funds’ investment strategies, triggering the recognition of taxable gains and losses on the sale of Fund investments, requiring the Funds to maintain higher cash balances to meet redemption requests, and experiencing increased transaction costs. A Fund that invests a significant amount of its assets in overseas markets is particularly susceptible to the risk of certain investors using a strategy known as time-zone arbitrage. Investors using this strategy attempt to take advantage of the differences in value of foreign securities that might result from events that occur between the close of the foreign securities market on which a foreign security is traded and the time at which the Fund calculates its NAV.

The Funds and/or their service providers will take steps reasonably designed to detect and deter frequent trading by shareholders pursuant to the Funds’ policies and procedures described in this prospectus and approved by the Funds’ Board. The Funds seek to discourage short-term trading by using fair value pricing procedures to fair value certain investments under some circumstances. For purposes of applying these policies, the Funds’ service providers may consider the trading history of accounts under common ownership or control. The Funds’ policies and procedures include:

Ÿ Restrictions on shareholders from making more than one (1) “round trip” into and out of a Fund within 14 days or more than two (2) “round trips” within any continuous 90 day period. If a shareholder exceeds either “round trip” restriction, he or she may be deemed a “Market Timer,” and the Funds and/or their service providers may, at their discretion, reject any additional purchase orders. The Funds define a round trip as a purchase into a Fund by a shareholder, followed by a subsequent redemption out of the Fund. Anyone considered to be a Market Timer by the Funds, the Adviser, the Subadviser or a shareholder servicing agent may be notified in writing of their designation as a Market Timer; and

Ÿ Reserving the right to reject any purchase request by any investor or group of investors for any reason without prior notice, including, in particular, if the Funds or the Adviser reasonably believes that the trading activity would be harmful or disruptive to the Funds.

The Funds and/or their service providers seek to apply these policies to the best of their abilities uniformly and in a manner they believe is consistent with the interests of the Funds’ long-term shareholders.

Although these policies are designed to deter frequent trading, none of these measures alone, nor all of them taken together eliminate, the possibility that frequent trading in the Funds will occur, particularly with respect to trades placed by shareholders that invest in the Funds through omnibus arrangements maintained by brokers, retirement plan accounts and other financial intermediaries. Purchase and redemption transactions submitted to the Funds by these intermediaries reflect the transactions of multiple beneficial owners whose individual transactions are not automatically disclosed to the Funds. Therefore, the Funds rely in large part on the intermediaries who maintain omnibus arrangements (which may represent a majority of Fund shares) to aid in the Funds’ efforts to detect and deter short-term trading. The Funds monitor trading activity at the omnibus account level and look for activity that indicates potential short-term trading. If they detect suspicious trading activity, the Funds contact the intermediaries to determine whether the short-term trading policy has been violated and may request and

21

MARKET TIMING POLICIES AND PROCEDURES, DISTRIBUTION OF FUND SHARES AND SHAREHOLDER SERVICING PLANS

receive personal identifying information and transaction histories for some or all beneficial owners to make this determination. If a Fund believes that a shareholder has violated the short-term trading policy, it will take further steps to prevent any future short-term trading by such shareholder in accordance with the policy. The Funds cannot guarantee the accuracy of the information provided by the intermediaries and may not always be able to track short-term trading affected through these intermediaries. A Fund has the right to terminate an intermediary’s ability to invest in a Fund if excessive trading activity persists and a Fund or its Adviser or Subadviser reasonably believes that such termination would be in the best interests of long-term shareholders. In addition to the Funds’ market timing policies and procedures described above, you may be subject to the market timing policies and procedures of the intermediary through which you invest. Please consult with your intermediary for additional information regarding its frequent trading restrictions.

Distribution of Fund Shares

Distribution of Fund Shares Generally

From their own assets, the Adviser, the Subadviser or their affiliates may make payments based on gross sales and current assets to selected brokerage firms or institutions. The amount of these payments may be substantial. The minimum aggregate sales required for eligibility for such payments, and the factors in selecting the brokerage firms and institutions to which they will be made, are determined from time to time by the Adviser or Subadviser. Furthermore, the Adviser, the Subadviser or their affiliates may pay fees from their own capital resources to financial intermediaries (such as brokers, banks, financial advisers and retirement plan service providers) to compensate them for providing distribution-related or shareholder services, for marketing expenses they incur, for travel and lodging in connection with educational events or to pay for the opportunity to have them distribute the Funds.

The amount of these payments is determined by the Adviser or the Subadviser and may differ among financial intermediaries. Such payments may provide incentives for financial intermediaries to make shares of the Funds available to their customers, and may allow the Funds greater access to such financial intermediaries and their customers than would be the case if no payments were made. You may wish to consider whether such arrangements exist when evaluating any recommendation to purchase shares of the Funds.

Please refer to the SAI for more information regarding these arrangements.

Distribution Plan — A Shares and C Shares

The A Shares and C Shares of each Fund have adopted a distribution plan that allows the Fund to pay distribution and service fees for the sale and distribution of its shares, and for services provided to shareholders. Because these fees are paid out of a Fund’s assets continuously, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.

Broker-dealers who initiate and are responsible for selling C Shares may receive an initial payment at the time of sale of 1.00% and annual 12b-1 payout effective in the 13^th month of 1.00%. Through the distribution plan, the Fund’s Distributor is reimbursed for these payments, as well as other distribution related services provided by the Distributor. For A Shares, each Fund’s distribution plan authorizes payment of up to the amount shown under “Maximum Fee” in the table that follows. Currently, however, the Board has only approved payment of up to the amount shown under “Current Approved Fee” in the table that follows. Fees are shown as a percentage of average daily net assets of the Fund’s A Shares.

	Maximum Fee		Current Approved Fee
Seix Floating Rate High Income Fund		0.35%		0.30%

For C Shares, the maximum distribution fee is 1.00% of the average daily net assets of a Fund’s C Shares.

The Fund may provide financial assistance in connection with pre-approved seminars, conferences and advertising to the extent permitted by applicable state or self-regulatory agencies, such as the Financial Industry Regulatory Authority.

Shareholder Servicing Plans

With respect to the A Shares and I Shares of certain of the Funds, the A Shares and I Shares Shareholder Servicing Plan permits the A Shares and I Shares of that Fund to pay financial intermediaries for shareholder support services they provide, at a rate of up to 0.20% of the average daily net assets of each of the A Shares and I Shares of that Fund. Financial intermediaries include brokers, dealers, banks (including bank trust departments), trust companies, registered investment advisers, financial planners, retirement plan administrators, insurance companies, and any other institution having a service, administration, or any similar arrangement with the Funds or their service

SHAREHOLDER SERVICING PLANS, DIVIDENDS AND DISTRIBUTIONS, HOUSEHOLD MAILINGS AND TAXES

providers. The shareholder support services may include, among others, providing general shareholder liaison services (including responding to shareholder inquiries), providing information on shareholder investments, and establishing and maintaining shareholder accounts and records.

Dividends and Distributions

Each Fund declares dividends daily and pays these dividends monthly. Each Fund makes distributions of its net realized capital gains, if any, at least annually. If you own Fund shares on a Fund’s record date, you will be entitled to receive the distribution.

You will receive dividends and distributions in the form of additional Fund shares unless you elect to receive payment in cash. To elect cash payment, you must notify the Funds in writing prior to the date of the distribution. Your election will be effective for dividends and distributions paid after the Funds receive your written notice. To cancel your election, simply send the Funds written notice.

Shareholders of the Funds are entitled to receive dividends declared starting on the next business day after a purchase is received in good order.

Shareholders of the Funds are entitled to receive dividends declared on the day their shares are redeemed.

401(k) plan participants will receive dividends and distributions in the form of additional Fund shares if the participant owns shares of a Fund on the date the dividend or distribution is allocated by the 401(k) plan. Therefore, a participant will not receive a dividend or distribution if the participant does not own shares of the applicable Fund on the date the dividend or distribution is allocated.

Household Mailings

To reduce expenses, we may mail only one copy of the Fund’s prospectus and each annual and semi-annual report to those addresses shared by two or more accounts. If you wish to receive individual copies of these documents, please call us at 1-888-784-3863 (or contact your financial institution). We will begin sending you individual copies thirty days after receiving your request.

Taxes

Please consult your tax advisor regarding your specific questions about U.S. federal, state, local, and foreign tax considerations relating to any investment in any Fund.

Summarized below are some important tax issues that affect the Funds and their shareholders. This summary is based on current tax laws, which may change. More information on taxes is in the Funds’ SAI.

Each Fund will distribute substantially all of its net investment income and its net realized capital gains, if any, at least annually. The dividends and distributions you receive may be subject to federal, state and local taxation, depending upon your tax situation. Distributions you receive from a Fund may be taxable whether or not you reinvest them in additional shares.

Income distributions are generally taxable as ordinary income. Capital gains distributions (i.e., distributions of the excess of net long-term capital gain over net short-term capital loss, if any) are generally taxable at the rates applicable to long-term capital gains. Long-term capital gains are generally taxable to noncorporate shareholders at rates of up to 20%. Distributions from a Fund’s net short-term capital gains are generally taxable as ordinary income. A high portfolio turnover rate and the use of certain derivatives may cause a Fund to recognize higher amounts of short-term capital gains.

If a Fund declares a dividend in October, November or December, payable to shareholders of record in such a month, and pays it in January of the following year, you will be taxed on the dividend as if you received it in the year in which it was declared.

If you invest in a Fund shortly before a capital gain distribution, generally you will pay a higher price per share and, unless you are exempt from tax, you will pay taxes on the amount of the distribution.

Distributions from a Fund and capital gains on a disposition of Fund shares are subject to a 3.8% U.S. federal Medicare contribution tax on all or a portion of the “net investment income” of individuals with incomes exceeding $200,000 ($250,000 if married and filing jointly). This 3.8% tax also applies to all or a portion of the undistributed net investment income of certain shareholders that are estates and trusts. “Net investment income” for this purpose does not include exempt-interest dividends (described below).

Each Fund in which you invest will inform you shortly after the close of each calendar year of the amounts of

23

TAXES

your distributions that may qualify as ordinary income dividends, exempt-interest dividends, and capital gain distributions.

You must provide your social security number or other taxpayer identification number to a Fund along with any certifications required by the Internal Revenue Service. If you do not, or if it is otherwise legally required to do so, a Fund will apply “backup withholding” tax on your dividends (including exempt-interest dividends) and other distributions, sale proceeds and any other payments to you that are subject to backup withholding. The backup withholding rate is 28%.

Dividends and distributions will accumulate on a tax-deferred basis if you are investing through a 401(k) plan or any other employer-sponsored retirement or savings plan that qualifies for tax-advantaged treatment under federal income tax laws. Generally, you will not owe taxes on these distributions until you begin withdrawals from the plan. Withdrawals from the plan are subject to numerous complex and special tax rules and may be subject to a penalty tax in the case of premature withdrawals. You should consult your tax advisor or plan administrator regarding the tax rules governing your retirement or savings plan.

Certain Funds may be able to pass along a tax credit for foreign income taxes they pay. In such event, the applicable Fund will provide you with the information necessary to reflect such foreign taxes on your federal income tax return.
