Portfolio Turnover

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

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.

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:

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

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 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.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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 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.

The bar chart and the performance table that follow illustrate the risks and volatility of an investment in the Fund. The Fund’s past performance (before and after taxes) does not indicate how the Fund will perform in the future. The Fund began operating on March 1, 2006. Performance information for the A Shares and C Shares prior to their inception on May 8, 2006 and August 2, 2007, respectively, is that of the I Shares of the Fund. The performance of I Shares has not been adjusted to reflect the Fund’s A Share or C Share expenses. If it had been, the performance would have been lower. As of the fiscal year ended March 31, 2014, the Fund had not issued IS Shares. Performance information for IS shares will be included after the share class has been in operation for one complete calendar year. Updated performance information is available by contacting the RidgeWorth Funds at 1-888-784-3863 or by visiting www.ridgeworth.com. The annual returns in the bar chart which follows are for the I Shares without reflecting payment of any sales charge; if they did reflect such payment of sales charges, annual returns would be lower.
