The Fund invests, under normal market conditions, primarily in a wide variety of international equity securities issued throughout the world, normally excluding the U.S. The Fund invests primarily in a diversified portfolio of common stocks and preferred stocks of foreign issuers. The Fund will also use futures, swaps, warrants, options, and structured investments, which are types of derivatives, to hedge risk and to remain fully invested, to maintain liquidity, to increase total return, or to manage exposure to a specific currency, country or region. The portfolio managers manage the Fund as a core international equity product that may invest in both &#8220;growth&#8221; and &#8220;value&#8221; securities primarily of mid- to large-capitalization companies, which the portfolio managers currently view to be companies that have a market capitalization greater than $2.5 billion as determined at the time of purchase. The portfolio managers seek to invest in securities in industries and companies they believe are experiencing favorable demand for their products or services. The portfolio managers screen to identify those companies with above average earnings potential, industry dominance, operating in industries undergoing dramatic change and that are market leaders in developing industries. The portfolio managers may also consider expected levels of inflation, government policies or actions, currency relationships and prospects for economic growth.</p><p> The portfolio manager uses both a bottom-up and top-down approach to select investments. The portfolio manager generally uses a bottom-up approach that focuses on company specific factors for selecting securities in developed markets. The portfolio manager generally uses a top-down approach for investments in emerging markets, indices and exchange-traded funds (&#8220;ETFs&#8221;), focusing on economic and geopolitical factors in a given area. The portfolio manager generally uses both a bottom-up and a top-down approach in Japan. The portfolio manager will sell a security owned by the Fund if the portfolio manager believes that, on the upside, the security has run its course or, on the downside, the security has disappointed relative to peers. A security owned by the Fund also may be sold if the portfolio manager determines that the reasons for its purchase no longer exist, the security&#8217;s valuation no longer justifies the risk, the company&#8217;s balance sheet has deteriorated, the catalysts for purchase have disappeared, the company experiences a relative price decline, or the portfolio manager has lost confidence in senior management of the company.</p><p> In selecting investments for the Fund, the portfolio managers focus on securities located in at least five countries, although the Fund may at times invest in fewer than five countries. The Fund will normally invest at least 65% of its total assets in no fewer than three different countries outside the U.S. The Fund may invest up to 35% of its total assets in the securities of issuers located in emerging markets.</p><p> The Fund also may invest in ETFs to gain exposure to a portion of the U.S. or a foreign market.</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> Market Risk:</b> The possibility that the Fund&#8217;s stock holdings will decline in price because of a broad stock market decline. 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 ovements.</p><p><b> Investment Style Risk:</b> The possibility that the market segment on which this Fund focuses &#8212; international stocks &#8212; will underperform other kinds of investments or market averages.</p><p><b> Foreign Investment Risk:</b> The possibility that the Fund&#8217;s investments in foreign securities will lose value because of currency exchange rate fluctuations, price volatility that may exceed the volatility of U.S. securities, uncertain political, social or economic conditions, lack of timely and reliable financial information and other factors. These risks are particularly pronounced for emerging markets. Investments in the securities of foreign issuers also entail risks such as market illiquidity, high trading costs, restrictions and limits on foreign ownership, limited legal recourse, prohibitions on the repatriation of foreign currencies and other considerations. Income that the Fund receives from investing in foreign securities may be subject to withholding and other taxes, which reduces the yield. In addition, foreign settlement procedures and trade regulators involve increased risk (such as delay in payment or delivery of securities). Custodial and/or settlement systems may not be fully developed in certain foreign markets, which involves additional risks.</p><p><b> Emerging Market Risk:</b> Investing in emerging markets can involve unique risks in addition to and greater than those generally associated with investing in developed markets. The securities markets of emerging countries are generally smaller, less developed, less liquid, and more volatile than the securities markets of the U.S. and developed markets. The risks of investing in emerging markets include greater social, political and economic uncertainties than in developed markets.</p><p> Emerging market economies are often dependent upon a few commodities or natural resources that may be significantly adversely affected by volatile price movements against those commodities or natural resources. Emerging market countries may experience high levels of inflation and currency devaluation and have fewer potential buyers for investments.</p><p> The securities markets and legal systems in emerging market countries may only be in a developmental stage and may provide few, or none, of the advantages and protections of markets or legal systems available in more developed countries. Less extensive legal remedies, difficulties in enforcing favorable legal judgments in foreign courts, and different securities clearance and settlement procedures are issues.</p><p> Additionally, if settlements do not keep pace with the volume of securities transactions, they may be delayed, potentially causing the Fund&#8217;s assets to be uninvested, the Fund to miss investment opportunities and potential returns, and the Fund to be unable to sell an investment.</p><p> Investments in emerging markets are considered to be speculative and may be highly volatile.</p><p><b> Foreign Currency Transaction Risk:</b> 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. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, intervention (or the failure to intervene) by U.S. or foreign governments, central banks or supranational entities such as the International Monetary Fund, or by the imposition of currency controls or other political developments in the U.S. or abroad.</p><p><b> Middle Capitalization Company Risk:</b> 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.</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>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&#8217;s exposure to securities markets values, interest rates or currency exchange rates. It is possible that the Fund&#8217;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&#8217;s use of derivatives such as options, 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> Options Risk:</b> 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 even if the contract is traded on an exchange. Exchanges may establish daily price fluctuation limits for options contracts and may halt trading if a contract&#8217;s price moves up or down more than the limit in a given day, making it impossible for the Fund to enter into new positions or close out existing positions. As a result, the Fund&#8217;s access to other assets held to cover the options positions could also be impaired.</p><p> As the writer of a covered call option, the Fund foregoes, during the option&#8217;s life, the opportunity to profit from increases in the market value of the security covering the call option above the sum of the premium and the strike price of the call, but retains the risk of loss should the price of the underlying security decline. As the Fund writes covered calls over more of its portfolio, its ability to benefit from capital appreciation becomes more limited. The writer of an option has no control over the time when it may be required to fulfill its obligation, but may terminate its position by entering into an offsetting option. Once an option writer has received an exercise notice, it cannot effect an offsetting transaction in order to terminate its obligation under the option and must deliver the underlying security at the exercise price.</p><p><b> ETF Risk:</b> When a Fund invests in an ETF, in addition to directly bearing expenses associated with its own operations, it will bear a pro rata portion of the ETF&#8217;s expenses. As a result, it may be more costly to own an ETF. In addition, lack of liquidity in an ETF could result in being more volatile than the underlying portfolio of securities.</p><p> For more information about the Fund&#8217;s risks, please see the Fund&#8217;s prospectus or statement of additional information.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

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&#8217;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.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 Narrative126Risk/Return Summary - Sterling Capital International Fund (Class Institutional) (Sterling Capital International Fund, Prospectus, Institutional Class)UnKnownUnKnownUnKnownUnKnownfalsetrue
