The Fund should place these additional captions directly below the "Total Annual Fund Operating Expenses" caption of the table and should use appropriate descriptive captions, such as "Fee Waiver [and/or Expense Reimbursement]" and "Total Annual Fund Operating Expenses After Fee Waiver [and/or Expense Reimbursement]," respectively.

The Fund will invest the portion of its assets invested in corporate bonds primarily in investment grade (rated at the time of purchase in one of the four highest rating categories by a nationally recognized statistical rating organization, or are determined by the portfolio manager to be of comparable quality) corporate bonds. The Fund may invest up to 25% of its total assets in bonds that are below investment grade, which are commonly referred to as “high yield” or “junk” bonds, and/or foreign and emerging market bonds.</p><p>In managing the portfolio, the portfolio manager uses a “top down” investment management approach focusing on interest rate risk, allocation among sectors, credit risk, and individual securities selection. The portfolio manager focuses on macro trends in the economy to establish a duration target relative to benchmark duration that reflects the outlook for the future direction of interest rates. For yield curve management, in addition to the trend in interest rates, other factors such as future inflation expectations, supply factors, and forward curve analysis are considered. Sector weightings are driven by a combination of the portfolio manager’s macro view on interest rates and volatility as well as relative spread analysis. Utilizing fundamental analysis the portfolio manager then selects individual securities consistent with the target by looking for the best relative values within particular sectors. The analysis includes an attempt to understand the structure and embedded features of potential securities. Features that are analyzed include puts, calls, sinking fund requirements, prepayment and extension risk, and individual company financial data for potential corporate holdings. Scenario analysis is the primary tool employed for these assessments. The portfolio manager may consider selling a security owned by the Fund to reduce exposure to a particular sector, if the portfolio manager sees a deterioration in the underlying fundamentals of an issuer or if the actions of the issuer violate the investment thesis of owning the security, when the portfolio managers finds other attractive securities that the portfolio manager believes are less expensive and offer relatively greater income or growth potential, and in response to macro level adjustments to duration and yield curve contributions.</p><p>The Fund may invest in certain types of derivative instruments for hedging and investment purposes. Although the Fund may invest in derivatives of any kind, the Fund currently expects to invest in futures contracts to gain efficient investment exposures as an alternative to cash investments or to hedge against portfolio exposures, and credit default swaps and interest rate swaps to gain indirect exposure to interest rates, issuers, or currencies, or to hedge against portfolio exposures.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

An investment in the Fund is not a deposit or obligation of any bank, is not endorsed or guaranteed by any bank and is not insured by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. You may lose money by investing in the Fund. Below are all of the principal risks of investing in the Fund.</p><p><b> Interest Rate Risk:</b> The possibility that the value of the Fund’s investments will decline due to an increase in interest rates. Interest rate risk is generally high for longer-term bonds and low for shorter-term bonds.</p><p><b> Credit Risk:</b> The possibility that an issuer cannot make timely interest and principal payments on its debt securities such as bonds. The lower a security’s rating, the greater its credit risk.</p><p><b> Income Risk:</b> The possibility that the Fund’s income will decline due to a decrease in interest rates. Income risk is generally high for shorter-term bonds and low for longer term bonds.</p><p><b>Counterparty Risk:</b> The possibility that a counterparty to a contract will default or otherwise become unable to honor a financial obligation.</p><p><b> Liquidity Risk:</b> The possibility that certain securities may be difficult or impossible to sell at the time and the price that would normally prevail in the market. 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.</p><p><b> Estimated Maturity Risk:</b> 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.</p><p><b> Prepayment/Call Risk:</b> 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. Some of these securities may receive little or no collateral protection from the underlying assets and are thus subject to the risk of default described under “Credit Risk”. The risk of such defaults is generally higher in the case of mortgage-backed investments that include so-called “sub-prime” mortgages. The structure of some of these securities may be complex and there may be less available information than other types of debt securities. If a significant number of the mortgages underlying a mortgage-backed bond are refinanced, the bond may be “prepaid.” 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. Rapid changes in prepayment and call rates can cause bond prices and yields to be volatile.</p><p><b> High-Yield/High-Risk Debt Securities:</b> High-yield/high-risk debt securities are securities that are rated below investment grade by the primary rating agencies. These securities are considered speculative and involve greater risk of loss than investment grade debt securities.</p><p><b> U.S. Government Securities Risk:</b> The Fund invests in U.S. Government securities or its agencies (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.</p><p><b> Foreign Investment Risk:</b> Foreign securities involve risks not typically associated with investing in U.S. securities. 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.</p><p><b> Derivatives Risk:</b> The possibility that the Fund will suffer a loss from its use of derivatives. There is no guarantee that the use of derivatives will be effective or that suitable transactions will be available. 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. Even a small investment in derivatives can have a significant impact on the Fund’s exposure to securities markets values, interest rates or currency exchange rates. It is possible that the Fund’s liquid assets may be insufficient to support its obligations under its derivatives positions. Use of derivatives for non-hedging purposes is considered a speculative practice and involves greater risks than are involved in hedging. 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 greater for swaps and other over-the-counter traded derivatives), the risk of difficulties in pricing and valuation, the risk that changes in the value of a derivative may not correlate perfectly with relevant assets, rates or indices, and the risk of losing more than the initial margin required to initiate derivatives positions. There is also the risk that the Fund may be unable to terminate or sell a derivatives position at an advantageous time or price.</p><p><b> Mortgage-Backed Securities Risk:</b> Mortgage-backed securities often involve risks that are different from or more acute than risks associated with other types of debt instruments. For instance, these 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. This is known as extension risk. Mortgage-backed securities are also subject to pre-payment risk. Due to their often complicated structures, various mortgage-backed securities may be difficult to value and may constitute illiquid securities. The value of mortgage-backed securities may be substantially dependent on the servicing of the underlying asset pools, and are therefore subject to risks associated with negligence by, or defalcation of, their servicers. 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.</p><p> For more information about the Fund’s risks, please see the Fund’s prospectus or SAI.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Class A Shares and are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. After-tax returns for Class B and C Shares will vary.falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringIf the Fund has annual returns for at least one calendar year, provide a table showing the Fund's (A) average annual total return; (B) average annual total return (after taxes on distributions); and (C) average annual total return (after taxes on distributions and redemption). A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also shouldshow the returns of an appropriate broadbased securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Paragraph 2 -Subparagraph iv -Subsection b falsefalsePerformance Table Narrative128Risk/Return Summary - Sterling Capital Total Return Bond Fund (Class A, B and C) (Sterling Capital Total Return Bond Fund, Prospectus, Class A, B and C)UnKnownUnKnownUnKnownUnKnownfalsetrue
