Risk [Text Block]

Market Risk: The possibility that the Fund’s stock holdings will decline in price because of a stock market decline, or other domestic, regional, or global events. Markets generally move in cycles, with periods of rising prices followed by periods of falling prices. The value of your investment will tend to increase or decrease in response to these movements.

A and C Shares | STERLING CAPITAL BEHAVIORAL LARGE CAP VALUE EQUITY FUND | Investment Style Risk  
Prospectus [Line Items]  
Risk [Text Block]

Investment Style Risk: The possibility that a market segment on which this Fund focuses — large cap stocks, value stocks and momentum stocks — will underperform other kinds of investments or market averages. A value stock may decrease in price or may not increase in price as anticipated by the portfolio manager if other investors fail to recognize the company’s value or the factors that the portfolio manager believes will cause the stock price to increase do not occur. A stock owned primarily for its momentum characteristics may start to underperform abruptly. In addition, the Fund’s focus on behavioral finance principles may cause the Fund to underperform funds that do not employ a behavioral finance strategy. There can be no guarantee that the factors that the Fund’s investment adviser considers in selecting stocks, and the weight that the adviser puts on each factor, will be effective in identifying and capitalizing on stock price anomalies.

Risk [Text Block]

Mid Capitalization Company Risk: Investments in middle capitalization companies may be riskier, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

A and C Shares | STERLING CAPITAL BEHAVIORAL LARGE CAP VALUE EQUITY FUND | Real Estate-Related Investment and REIT Risk  
Prospectus [Line Items]  
Risk [Text Block]

Real Estate-Related Investment and REIT Risk: Real estate-related investments may decline in value as a result of factors affecting the real estate industry. Risks associated with investments in securities of companies in the real estate industry include decline in the value of the underlying real estate, default, prepayment, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and creditworthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which the Fund invests.

Prospectus [Line Items]  
Risk [Text Block]

ETF Risk: The risks associated with investing in ETFs include the risks of owning the underlying securities the ETF is designed to track. Lack of liquidity in an ETF could result in the ETF being more volatile than the underlying portfolio of securities. When the Fund invests in an ETF, in addition to directly bearing expenses associated with its own operations, the Fund will bear a pro rata portion of the ETF’s expenses. As a result, it may be more costly to own an ETF than owning the underlying portfolio of securities directly.

Risk [Text Block]

Options Risk: There are significant differences between the securities and options markets that could result in an imperfect correlation between these markets, causing an options transaction not to achieve its objectives. A decision as to whether, when and how to use options involves the exercise of skill and judgment, and even a well conceived transaction may be unsuccessful to some degree because of market behavior or unexpected events. There can be no assurance that a liquid secondary market will exist for any particular option at a particular time; as a result, it may be costly to liquidate options. There is also no assurance that a liquid market will exist for any particular option contract on an exchange.

Prepayment/Call Risk: When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss. Call risk is the possibility that, during periods of declining interest rates, a bond issuer will “call” — or repay — higher-yielding bonds before their stated maturity date. In both cases, investors receive their principal back and are typically forced to reinvest it in bonds that pay lower interest rates.

Municipal Securities Risk: Municipal obligations are issued by or on behalf of states, territories and possessions of the United States and their political subdivisions, agencies and instrumentalities and the District of Columbia to obtain funds for various public purposes. Municipal obligations are subject to more credit risk than U.S. government securities that are supported by the full faith and credit of the United States. The ability of municipalities to meet their obligations will depend on the availability of tax and other revenues, economic, political and other conditions within the state and municipality, and the underlying fiscal condition of the state and municipality. As with other fixed income securities, municipal securities also expose their holders to market risk because their values typically change as interest rates fluctuate.

Mortgage-Backed and Asset-Backed Securities Risk: Mortgage-backed and other asset-backed securities may be particularly sensitive to changes in prevailing interest rates. Rising interest rates tend to extend the duration of mortgage-backed securities, making them more sensitive to changes in interest rates, and may reduce the market value of the securities. Mortgage-backed securities are also subject to pre-payment risk. Due to their often complicated structures, various mortgage-backed and asset-backed securities may be difficult to value and may constitute illiquid securities. Furthermore, debtors may be entitled to the protection of a number of state and federal consumer protection credit laws with respect to these securities, which may give the debtor the right to avoid or reduce payment.

Collateralized Loan Obligations Risk: Collateralized loan obligations are structured investment vehicles typically collateralized by a pool of loans, which may include, among others, senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. Collateralized loan obligations are subject to the risks of substantial losses, including losses due to actual defaults by borrowers of the loans underlying the collateralized loan obligations, which will be greater during periods of economic or financial stress. Collateralized loan obligations may also lose value due to collateral defaults and impairment of subordinate tranches, market anticipation of defaults, and investor aversion to collateralized loan obligation securities as a class. The Fund may invest in collateralized loan obligations that hold loans of uncreditworthy borrowers, which may absorb losses from underlying borrower defaults before senior tranches. Investments in such collateralized loan obligations present a greater risk of loss. In addition, collateralized loan obligations are subject to interest rate risk, credit risk, prepayment/call risk and fixed income market risk.

A and C Shares | STERLING CAPITAL SHORT DURATION BOND FUND | Derivatives Risk  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk: The possibility that the Fund will suffer a loss from its use of derivatives. The primary risk with many derivatives is that they can amplify a gain or loss, potentially earning or losing substantially more money than the actual cost of the derivative instrument. It is possible that the Fund’s liquid assets may be insufficient to support its obligations under its derivatives positions. The Fund’s use of derivatives such as futures transactions and swap transactions involves other risks, such as the credit risk relating to the other party to a derivative contract (which is heightened for over-the-counter swaps and other derivatives as compared to centrally cleared derivatives), the risk of difficulties in pricing and valuation, and the risk that changes in the value of a derivative may not correlate perfectly with relevant assets, rates or indices. There is also the risk that the Fund may be unable to terminate or sell a derivatives position at an advantageous time or price. When the Fund uses credit default swaps to gain indirect long exposure to an issuer or a fixed income security by selling credit protection on such issuer or security, the Fund is exposed to the risk that it will be required to pay the full notional value of the swap contract in the event of a default.

In both cases, investors receive their principal back and are typically forced to reinvest it in bonds that pay lower interest rates.

Estimated Maturity Risk: The possibility that an underlying security holder will exercise its right to pay principal on an obligation earlier or later than expected. This may happen when there is a rise or fall in interest rates. These events may shorten or lengthen the duration (i.e., interest rate sensitivity) and potentially reduce the value of these securities.

Risk [Text Block]

Municipal Securities Risk: Municipal obligations are issued by or on behalf of states, territories and possessions of the United States and their political subdivisions, agencies and instrumentalities and the District of Columbia to obtain funds for various public purposes. Municipal obligations are subject to more credit risk than U.S. government securities that are supported by the full faith and credit of the United States. The ability of municipalities to meet their obligations will depend on the availability of tax and other revenues, economic, political and other conditions within the state and municipality, and the underlying fiscal condition of the state and municipality. As with other fixed income securities, municipal securities also expose their holders to market risk because their values typically change as interest rates fluctuate.

Prospectus [Line Items]  
Risk [Text Block]

Mortgage-Backed and Asset-Backed Securities Risk: Mortgage-backed and other asset-backed securities may be particularly sensitive to changes in prevailing interest rates. Rising interest rates tend to extend the duration of mortgage-backed securities, making them more sensitive to changes in interest rates, and may reduce the market value of the securities. Mortgage-backed securities are also subject to pre-payment risk. Due to their often complicated structures, various mortgage-backed and asset-backed securities may be difficult to value and may constitute illiquid securities. Furthermore, debtors may be entitled to the protection of a number of state and federal consumer protection credit laws with respect to these securities, which may give the debtor the right to avoid or reduce payment.

Risk [Text Block]

Collateralized Loan Obligations Risk: Collateralized loan obligations are structured investment vehicles typically collateralized by a pool of loans, which may include, among others, senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. Collateralized loan obligations are subject to the risks of substantial losses, including losses due to actual defaults by borrowers of the loans underlying the collateralized loan obligations, which will be greater during periods of economic or financial stress. Collateralized loan obligations may also lose value due to collateral defaults and impairment of subordinate tranches, market anticipation of defaults, and investor aversion to collateralized loan obligation securities as a class. The Fund may invest in collateralized loan obligations that hold loans of uncreditworthy borrowers, which may absorb losses from underlying borrower defaults before senior tranches. Investments in such collateralized loan obligations present a greater risk of loss. In addition, collateralized loan obligations are subject to interest rate risk, credit risk, prepayment/call risk and fixed income market risk.

Derivatives Risk: The possibility that the Fund will suffer a loss from its use of derivatives. The primary risk with many derivatives is that they can amplify a gain or loss, potentially earning or losing substantially more money than the actual cost of the derivative instrument. It is possible that the Fund’s liquid assets may be insufficient to support its obligations under its derivatives positions. The Fund’s use of derivatives such as futures transactions and swap transactions involves other risks, such as the credit risk relating to the other party to a derivative contract (which is heightened for over-the-counter swaps and other derivatives as compared to centrally cleared derivatives), the risk of difficulties in pricing and valuation, and the risk that changes in the value of a derivative may not correlate perfectly with relevant assets, rates or indices. There is also the risk that the Fund may be unable to terminate or sell a derivatives position at an advantageous time or price.

Prepayment/Call Risk: When obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss. Call risk is the possibility that, during periods of declining interest rates, a bond issuer will “call” — or repay — higher-yielding bonds before their stated maturity date. In both cases, investors receive their principal back and are typically forced to reinvest it in bonds that pay lower interest rates.

Municipal Securities Risk: Municipal obligations are issued by or on behalf of states, territories and possessions of the United States and their political subdivisions, agencies and instrumentalities and the District of Columbia to obtain funds for various public purposes. Municipal obligations are subject to more credit risk than U.S. government securities that are supported by the full faith and credit of the United States. The ability of municipalities to meet their obligations will depend on the availability of tax and other revenues, economic, political and other conditions within the state and municipality, and the underlying fiscal condition of the state and municipality. As with other fixed income securities, municipal securities also expose their holders to market risk because their values typically change as interest rates fluctuate.

Prepayment/Call Risk: When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss. Call risk is the possibility that, during periods of declining interest rates, a bond issuer will “call” — or repay — higher-yielding bonds before their stated maturity date. In both cases, investors receive their principal back and are typically forced to reinvest it in bonds that pay lower interest rates.

Municipal Securities Risk: Municipal obligations are issued by or on behalf of states, territories and possessions of the United States and their political subdivisions, agencies and instrumentalities and the District of Columbia to obtain funds for various public purposes. Municipal obligations are subject to more credit risk than U.S. government securities that are supported by the full faith and credit of the United States. The ability of municipalities to meet their obligations will depend on the availability of tax and other revenues, economic, political and other conditions within the state and municipality, and the underlying fiscal condition of the state and municipality. As with other fixed income securities, municipal securities also expose their holders to market risk because their values typically change as interest rates fluctuate.

Mortgage-Backed and Asset-Backed Securities Risk: Mortgage-backed and other asset-backed securities may be particularly sensitive to changes in prevailing interest rates. Rising interest rates tend to extend the duration of mortgage-backed securities, making them more sensitive to changes in interest rates, and may reduce the market value of the securities. Mortgage-backed securities are also subject to pre-payment risk. Due to their often complicated structures, various mortgage-backed and asset-backed securities may be difficult to value and may constitute illiquid securities. Furthermore, debtors may be entitled to the protection of a number of state and federal consumer protection credit laws with respect to these securities, which may give the debtor the right to avoid or reduce payment.

Collateralized Loan Obligations Risk: Collateralized loan obligations are structured investment vehicles typically collateralized by a pool of loans, which may include, among others, senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. Collateralized loan obligations are subject to the risks of substantial losses, including losses due to actual defaults by borrowers of the loans underlying the collateralized loan obligations, which will be greater during periods of economic or financial stress. Collateralized loan obligations may also lose value due to collateral defaults and impairment of subordinate tranches, market anticipation of defaults, and investor aversion to collateralized loan obligation securities as a class. The Fund may invest in collateralized loan obligations that hold loans of uncreditworthy borrowers, which may absorb losses from underlying borrower defaults before senior tranches. Investments in such collateralized loan obligations present a greater risk of loss. In addition, collateralized loan obligations are subject to interest rate risk, credit risk, prepayment/call risk and fixed income market risk.

Collateralized loan obligations may also lose value due to collateral defaults and impairment of subordinate tranches, market anticipation of defaults, and investor aversion to collateralized loan obligation securities as a class. The Fund may invest in collateralized loan obligations that hold loans of uncreditworthy borrowers, which may absorb losses from underlying borrower defaults before senior tranches. Investments in such collateralized loan obligations present a greater risk of loss. In addition, collateralized loan obligations are subject to interest rate risk, credit risk, prepayment/call risk and fixed income market risk.

Foreign Currency Transaction Risk: Funds that invest directly in foreign currencies and in securities that trade in, or receive revenues in, foreign currencies are subject to the risk that those currencies will fluctuate in value relative to the U.S. dollar.

Institutional Shares | STERLING CAPITAL SHORT DURATION BOND FUND | Derivatives Risk  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk: The possibility that the Fund will suffer a loss from its use of derivatives. The primary risk with many derivatives is that they can amplify a gain or loss, potentially earning or losing substantially more money than the actual cost of the derivative instrument. It is possible that the Fund’s liquid assets may be insufficient to support its obligations under its derivatives positions. The Fund’s use of derivatives such as futures transactions and swap transactions involves other risks, such as the credit risk relating to the other party to a derivative contract (which is heightened for over-the-counter swaps and other derivatives as compared to centrally cleared derivatives), the risk of difficulties in pricing and valuation, and the risk that changes in the value of a derivative may not correlate perfectly with relevant assets, rates or indices. There is also the risk that the Fund may be unable to terminate or sell a derivatives position at an advantageous time or price. When the Fund uses credit default swaps to gain indirect long exposure to an issuer or a fixed income security by selling credit protection on such issuer or security, the Fund is exposed to the risk that it will be required to pay the full notional value of the swap contract in the event of a default.

Prepayment/Call Risk: When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss. Call risk is the possibility that, during periods of declining interest rates, a bond issuer will “call” — or repay — higher-yielding bonds before their stated maturity date. In both cases, investors receive their principal back and are typically forced to reinvest it in bonds that pay lower interest rates.

Municipal Securities Risk: Municipal obligations are issued by or on behalf of states, territories and possessions of the United States and their political subdivisions, agencies and instrumentalities and the District of Columbia to obtain funds for various public purposes. Municipal obligations are subject to more credit risk than U.S. government securities that are supported by the full faith and credit of the United States. The ability of municipalities to meet their obligations will depend on the availability of tax and other revenues, economic, political and other conditions within the state and municipality, and the underlying fiscal condition of the state and municipality. As with other fixed income securities, municipal securities also expose their holders to market risk because their values typically change as interest rates fluctuate.

Mortgage-Backed and Asset-Backed Securities Risk: Mortgage-backed and other asset-backed securities may be particularly sensitive to changes in prevailing interest rates. Rising interest rates tend to extend the duration of mortgage-backed securities, making them more sensitive to changes in interest rates, and may reduce the market value of the securities. Mortgage-backed securities are also subject to pre-payment risk. Due to their often complicated structures, various mortgage-backed and asset-backed securities may be difficult to value and may constitute illiquid securities. Furthermore, debtors may be entitled to the protection of a number of state and federal consumer protection credit laws with respect to these securities, which may give the debtor the right to avoid or reduce payment.

Prepayment/Call Risk: When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss. Call risk is the possibility that, during periods of declining interest rates, a bond issuer will “call” — or repay — higher-yielding bonds before their stated maturity date. In both cases, investors receive their principal back and are typically forced to reinvest it in bonds that pay lower interest rates.

Estimated Maturity Risk: The possibility that an underlying security holder will exercise its right to pay principal on an obligation earlier or later than expected. This may happen when there is a rise or fall in interest rates. These events may shorten or lengthen the duration (i.e., interest rate sensitivity) and potentially reduce the value of these securities.

Institutional Shares | STERLING CAPITAL QUALITY INCOME FUND | Mortgage-Backed and Asset-Backed Securities Risk  
Prospectus [Line Items]  
Risk [Text Block]

Mortgage-Backed and Asset-Backed Securities Risk: Mortgage-backed and other asset-backed securities may be particularly sensitive to changes in prevailing interest rates. Rising interest rates tend to extend the duration of mortgage-backed securities, making them more sensitive to changes in interest rates, and may reduce the market value of the securities. Mortgage-backed securities are also subject to pre-payment risk. Due to their often complicated structures, various mortgage-backed and asset-backed securities may be difficult to value and may constitute illiquid securities. Furthermore, debtors may be entitled to the protection of a number of state and federal consumer protection credit laws with respect to these securities, which may give the debtor the right to avoid or reduce payment.

Prospectus [Line Items]  
Risk [Text Block]

Collateralized Loan Obligations Risk: Collateralized loan obligations are structured investment vehicles typically collateralized by a pool of loans, which may include, among others, senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. Collateralized loan obligations are subject to the risks of substantial losses, including losses due to actual defaults by borrowers of the loans underlying the collateralized loan obligations, which will be greater during periods of economic or financial stress. Collateralized loan obligations may also lose value due to collateral defaults and impairment of subordinate tranches, market anticipation of defaults, and investor aversion to collateralized loan obligation securities as a class. The Fund may invest in collateralized loan obligations that hold loans of uncreditworthy borrowers, which may absorb losses from underlying borrower defaults before senior tranches. Investments in such collateralized loan obligations present a greater risk of loss. In addition, collateralized loan obligations are subject to interest rate risk, credit risk, prepayment/call risk and fixed income market risk.

Institutional Shares | STERLING CAPITAL QUALITY INCOME FUND | Derivatives Risk

Risk [Text Block]

Derivatives Risk: The possibility that the Fund will suffer a loss from its use of derivatives. The primary risk with many derivatives is that they can amplify a gain or loss, potentially earning or losing substantially more money than the actual cost of the derivative instrument. It is possible that the Fund’s liquid assets may be insufficient to support its obligations under its derivatives positions. The Fund’s use of derivatives such as futures transactions and swap transactions involves other risks, such as the credit risk relating to the other party to a derivative contract (which is heightened for over-the-counter swaps and other derivatives as compared to centrally cleared derivatives), the risk of difficulties in pricing and valuation, and the risk that changes in the value of a derivative may not correlate perfectly with relevant assets, rates or indices. There is also the risk that the Fund may be unable to terminate or sell a derivatives position at an advantageous time or price.

U.S. Government Securities Risk: The Fund invests in securities issued or guaranteed by the U.S. government or its agencies or instrumentalities (such as Fannie Mae or Freddie Mac securities). Although U.S. government securities issued directly by the U.S. government are guaranteed by the U.S. Treasury, other U.S. government securities issued by an agency or instrumentality of the U.S. government may not be. No assurance can be given that the U.S. government would provide financial support to its agencies and instrumentalities if not required to do so by law.

Private Placement Risk: Privately issued securities are restricted securities that are not publicly traded, and may be less liquid than those that are publicly traded. Accordingly, the Fund may not be able to redeem or resell its interests in a privately issued security at an advantageous time or at an advantageous price which may result in a loss to the Fund.

Prospectus [Line Items]  
Risk [Text Block]

Mortgage Dollar Roll Risk: The use of mortgage dollar rolls is a speculative technique involving leverage, and can have an economic effect similar to borrowing money for investment purposes. Mortgage dollar roll transactions involve the risk that the market value of the securities the Fund is required to purchase may decline below the agreed upon repurchase price of those securities. If the broker/dealer to whom the Fund sells securities becomes insolvent, the Fund’s right to purchase or repurchase securities may be restricted. Successful use of mortgage dollar rolls may depend upon the ability to correctly predict interest rates and prepayments. These transactions may increase the Fund’s portfolio turnover rate.

The ability of municipalities to meet their obligations will depend on the availability of tax and other revenues, economic, political and other conditions within the state and municipality, and the underlying fiscal condition of the state and municipality.

Investment Style Risk: The possibility that a market segment on which this Fund focuses — large cap stocks, value stocks and momentum stocks — will underperform other kinds of investments or market averages. A value stock may decrease in price or may not increase in price as anticipated by the portfolio manager if other investors fail to recognize the company’s value or the factors that the portfolio manager believes will cause the stock price to increase do not occur. A stock owned primarily for its momentum characteristics may start to underperform abruptly. In addition, the Fund’s focus on behavioral finance principles may cause the Fund to underperform funds that do not employ a behavioral finance strategy. There can be no guarantee that the factors that the Fund’s investment adviser considers in selecting stocks, and the weight that the adviser puts on each factor, will be effective in identifying and capitalizing on stock price anomalies.

When the Fund invests in an ETF, in addition to directly bearing expenses associated with its own operations, the Fund will bear a pro rata portion of the ETF’s expenses. As a result, it may be more costly to own an ETF than owning the underlying portfolio of securities directly.

Investment Style Risk: The possibility that a market segment on which this Fund focuses — small company stocks, value stocks and momentum stocks — will underperform other kinds of investments or market averages. A value stock may decrease in price or may not increase in price as anticipated by the portfolio manager if other investors fail to recognize the company’s value or the factors that the portfolio manager believes will cause the stock price to increase do not occur. A stock owned primarily for its momentum characteristics may start to underperform abruptly. In addition, the Fund’s focus on behavioral finance principles may cause the Fund to underperform funds that do not employ a behavioral finance strategy. There can be no guarantee that the factors that the Fund’s investment adviser considers in selecting stocks, and the weight that the adviser puts on each factor, will be effective in identifying and capitalizing on stock price anomalies.

A decision as to whether, when and how to use options involves the exercise of skill and judgment, and even a well conceived transaction may be unsuccessful to some degree because of market behavior or unexpected events. There can be no assurance that a liquid secondary market will exist for any particular option at a particular time; as a result, it may be costly to liquidate options.

Foreign securities may be adversely affected by various factors, including currency fluctuations and social, economic or political instability. These risks are particularly pronounced for emerging markets.

Preferred Stock Risk: Preferred stock represents an interest in a company that generally entitles the holder to receive, in preference to the holders of common stock, dividends and a fixed share of the proceeds resulting from a liquidation of the company. Preferred stocks are generally subordinated in right of payment to all debt obligations and creditors of the issuer.

The seller may have to lower the price, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Fund management or performance.

R6 Shares | STERLING CAPITAL SHORT DURATION BOND FUND | Prepayment/Call Risk

Risk [Text Block]

Prepayment/Call Risk: When mortgages and other obligations are prepaid and when securities are called, the Fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss. Call risk is the possibility that, during periods of declining interest rates, a bond issuer will “call” — or repay — higher-yielding bonds before their stated maturity date. In both cases, investors receive their principal back and are typically forced to reinvest it in bonds that pay lower interest rates.

R6 Shares | STERLING CAPITAL SHORT DURATION BOND FUND | Estimated Maturity Risk

Estimated Maturity Risk: The possibility that an underlying security holder will exercise its right to pay principal on an obligation earlier or later than expected. This may happen when there is a rise or fall in interest rates. These events may shorten or lengthen the duration (i.e., interest rate sensitivity) and potentially reduce the value of these securities.

R6 Shares | STERLING CAPITAL SHORT DURATION BOND FUND | Mortgage-Backed and Asset-Backed Securities Risk  
Prospectus [Line Items]  
Risk [Text Block]

Mortgage-Backed and Asset-Backed Securities Risk: Mortgage-backed and other asset-backed securities may be particularly sensitive to changes in prevailing interest rates. Rising interest rates tend to extend the duration of mortgage-backed securities, making them more sensitive to changes in interest rates, and may reduce the market value of the securities. Mortgage-backed securities are also subject to pre-payment risk. Due to their often complicated structures, various mortgage-backed and asset-backed securities may be difficult to value and may constitute illiquid securities. Furthermore, debtors may be entitled to the protection of a number of state and federal consumer protection credit laws with respect to these securities, which may give the debtor the right to avoid or reduce payment.

Risk [Text Block]

Collateralized Loan Obligations Risk: Collateralized loan obligations are structured investment vehicles typically collateralized by a pool of loans, which may include, among others, senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. Collateralized loan obligations are subject to the risks of substantial losses, including losses due to actual defaults by borrowers of the loans underlying the collateralized loan obligations, which will be greater during periods of economic or financial stress. Collateralized loan obligations may also lose value due to collateral defaults and impairment of subordinate tranches, market anticipation of defaults, and investor aversion to collateralized loan obligation securities as a class. The Fund may invest in collateralized loan obligations that hold loans of uncreditworthy borrowers, which may absorb losses from underlying borrower defaults before senior tranches. Investments in such collateralized loan obligations present a greater risk of loss. In addition, collateralized loan obligations are subject to interest rate risk, credit risk, prepayment/call risk and fixed income market risk.

Foreign Currency Transaction Risk: Funds that invest directly in foreign currencies and in securities that trade in, or receive revenues in, foreign currencies are subject to the risk that those currencies will fluctuate in value relative to the U.S. dollar.

R6 Shares | STERLING CAPITAL SHORT DURATION BOND FUND | Derivatives Risk  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk: The possibility that the Fund will suffer a loss from its use of derivatives. The primary risk with many derivatives is that they can amplify a gain or loss, potentially earning or losing substantially more money than the actual cost of the derivative instrument. It is possible that the Fund’s liquid assets may be insufficient to support its obligations under its derivatives positions. The Fund’s use of derivatives such as futures transactions and swap transactions involves other risks, such as the credit risk relating to the other party to a derivative contract (which is heightened for over-the-counter swaps and other derivatives as compared to centrally cleared derivatives), the risk of difficulties in pricing and valuation, and the risk that changes in the value of a derivative may not correlate perfectly with relevant assets, rates or indices. There is also the risk that the Fund may be unable to terminate or sell a derivatives position at an advantageous time or price. When the Fund uses credit default swaps to gain indirect long exposure to an issuer or a fixed income security by selling credit protection on such issuer or security, the Fund is exposed to the risk that it will be required to pay the full notional value of the swap contract in the event of a default.

Municipal Securities Risk: Municipal obligations are issued by or on behalf of states, territories and possessions of the United States and their political subdivisions, agencies and instrumentalities and the District of Columbia to obtain funds for various public purposes. Municipal obligations are subject to more credit risk than U.S. government securities that are supported by the full faith and credit of the United States. The ability of municipalities to meet their obligations will depend on the availability of tax and other revenues, economic, political and other conditions within the state and municipality, and the underlying fiscal condition of the state and municipality. As with other fixed income securities, municipal securities also expose their holders to market risk because their values typically change as interest rates fluctuate.
