Expense, Narrative	rr_ExpenseNarrativeTextBlock	The table below describes the fees and expenses that you may pay if you buy and hold Class A 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 Class A Shares of the Frost Funds (Class A Shares purchased without an initial sales charge may be subject to a contingent deferred sales charge if redeemed within 12 months of purchase). More information about these and other discounts is available from your financial professional and in the section "Sales Charges" on page 104 of this prospectus.

Portfolio Turnover, Heading	rr_PortfolioTurnoverHeading	PORTFOLIO TURNOVER
Portfolio Turnover	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, 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 total annual fund operating expenses or in the example, affect the Fund's performance. During its most recent fiscal year, the Fund's portfolio turnover rate was 144% of the average value of its portfolio.

Investment Strategy, Heading	rr_StrategyHeading	PRINCIPAL INVESTMENT STRATEGY
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests at least 80% of its net assets in equity securities of small-capitalization companies. This investment policy may be changed by the Fund upon 60 days' prior notice to shareholders. The Fund uses a multi-manager approach, relying upon two sub-advisers, Cambiar Investors, LLC ("Cambiar") and Artio Global Management LLC ("Artio Global"), with differing investment philosophies to manage portions of the Fund's portfolio under the general supervision of the Fund's adviser, Frost Investment Advisors, LLC. The Fund intends to invest in companies that Cambiar and Artio Global believe are undervalued, profitable, and capable of generating significant cash flow. In managing the Fund, Cambiar will select and manage its portion of the Fund's portfolio with a bias toward value-oriented small-cap stocks while Artio Global will select and manage its portion of the Fund's portfolio with a bias toward growth-oriented small-cap stocks. Growth-oriented managers generally select stocks they believe have attractive growth and appreciation potential in light of such characteristics as revenue and earnings growth, expectations from sell side analysts, and relative valuation, while value-oriented managers generally select stocks they believe are attractively valued in light of fundamental characteristics such as earnings, capital structure and/or return on invested capital. In selecting investments for the Fund, Cambiar utilizes a bottom-up, research-focused investment philosophy that seeks to identify quality companies that are currently undervalued to their historical trading range, yet demonstrate catalysts not yet recognized by the market that could result in significant appreciation over a 1-2 year time horizon. While Cambiar may use various metrics in selecting securities for the Fund, a company must possess the following characteristics: attractive valuation, an identifiable performance catalyst(s) and material upside potential. In selecting investments for the Fund, Cambiar generally considers small-capitalization companies to be those companies with total market capitalizations less than $3 billion at the time of initial purchase. In implementing its sell discipline, Cambiar sells stocks once a stock reaches its price target, when there is a decline in fundamentals, or the anticipated catalyst at purchase fails to materialize. Stocks may also be sold in favor of a more attractive investment opportunity. Cambiar will also trim a holding if it becomes an outsized position within the Fund's portfolio. In selecting investments for the Fund, Artio Global will focus on companies that generally possess the following attributes: o companies with economic earnings or free cash flow generation; o companies with the capability to self fund and to avoid raising additional capital; o companies that provide products or services that change the behavior of the consumer or capital spender; o companies that provide products or services that have an opportunity to gain market share or carve out a niche in the market; and o companies with high gross margins and/or operating leverage with the potential for providing operating margin improvement. Generally, Artio Global will select securities of companies whose market capitalization at the time of purchase falls (i) within the market capitalization range of companies within the Russell 2000 Index or (ii) within the range of the three year average minimum and maximum market capitalizations of companies in the Russell 2000 Index as of December 31 of the three preceding years. As of December 31, 2010, the capitalization range of the Russell 2000 Index was $13.23 million to $4.44 billion and the three year average market capitalization range of the Russell 2000 Index was $8.35 million to $4.44 billion. Artio Global may sell securities included in the Fund's portfolio if a stock reaches its target price; relative investment opportunities exist; a company's fundamentals deteriorate; and/or if there is a distortion of a company's weighted average market capitalization. The Fund may engage in active and frequent trading of portfolio securities to achieve its investment objective.
Risk, Heading	rr_RiskHeading	PRINCIPAL RISKS
Risk, Narrative	rr_RiskNarrativeTextBlock	As with all mutual funds, a shareholder is subject to the risk that his or her investment could lose money. A FUND SHARE IS NOT A BANK DEPOSIT AND IT IS NOT INSURED OR GUARANTEED BY THE FDIC, OR ANY GOVERNMENT AGENCY. The principal risks affecting shareholders' investments in the Fund are set forth below. INITIAL PUBLIC OFFERINGS ("IPO") RISK -- The Fund may invest a portion of its assets in securities of companies offering shares in IPOs. IPOs may have a magnified performance impact on a fund with a small asset base. The impact of IPOs on the Fund's performance likely will decrease as the Fund's asset size increases, which could reduce the Fund's total returns. IPOs may not be consistently available to the Fund for investing. Because IPO shares frequently are volatile in price, the Fund may hold IPO shares for a very short period of time. This may increase the turnover of the Fund's portfolio and may lead to increased expenses for the Fund, such as commissions and transaction costs. By selling IPO shares, the Fund may realize taxable gains it will subsequently distribute to shareholders. In addition, the market for IPO shares can be speculative and/or inactive for extended periods of time. The limited number of shares available for trading in some IPOs may make it more difficult for the Fund to buy or sell significant amounts of shares without an unfavorable impact on prevailing prices. Holders of IPO shares can be affected by substantial dilution in the value of their shares, by sales of additional shares and by concentration of control in existing management and principal shareholders. EQUITY RISK -- Since it purchases equity securities, the Fund is subject to the risk that stock prices will fall over short or extended periods of time. Historically, the equity markets have moved in cycles, and the value of the Fund's equity securities may fluctuate drastically from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. These factors contribute to price volatility, which is the principal risk of investing in the Fund. SMALL-CAPITALIZATION COMPANY RISK -- The small-capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, these small- sized companies may pose additional risks, including liquidity risk, because these companies tend to have limited product lines, markets and financial resources, and may depend upon a relatively small management group. Therefore, small-capitalization stocks may be more volatile than those of larger companies. These securities may be traded over the counter or listed on an exchange. FOREIGN COMPANY RISK -- Investing in foreign companies, whether through investments made in foreign markets or made through the purchase of ADRs, which are traded on U.S. exchanges and represent an ownership in a foreign security, poses additional risks since political and economic events unique to a country or region will affect those markets and their issuers. These risks will not necessarily affect the U.S. economy or similar issuers located in the United States. In addition, investments in foreign companies are generally denominated in a foreign currency. As a result, changes in the value of those currencies compared to the U.S. dollar may affect (positively or negatively) the value of the Fund's investments. These currency movements may occur separately from, and in response to, events that do not otherwise affect the value of the security in the issuer's home country. While ADRs provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs continue to be subject to many of the risks associated with investing directly in foreign securities. ACTIVE TRADING RISK -- The Fund may engage in active and frequent trading of portfolio securities to achieve its investment objective. Active trading may cause the Fund to incur increased costs, which can lower the actual return of the Fund. Active trading may also increase short-term gains and losses, which affect taxes that must be paid. LIQUIDITY RISK -- Particular investments may be difficult to purchase or sell. The Fund may make investments that become less liquid in response to market developments or adverse investor perceptions, which may reduce the returns of the Fund because it may be unable to sell the illiquid securities at an advantageous time or price.

Bar Chart and Performance Table, Heading	rr_BarChartAndPerformanceTableHeading	PERFORMANCE INFORMATION
Performance, Narrative	rr_PerformanceNarrativeTextBlock	The bar chart and the performance table below illustrate the risks and volatility of an investment in the Fund by showing changes in the Fund's performance from year to year and by showing how the Fund's average annual total returns for 1 and 5 years and since inception compare with those of a broad measure of market performance. The performance information provided includes the returns of Institutional Class Shares for periods prior to April 25, 2008. Institutional Class Shares of the Fund are offered in a separate prospectus. Institutional Class Shares would have substantially similar performance as Class A Shares because the shares are invested in the same portfolio of securities and the annual returns would differ only to the extent that the expenses of Class A Shares are higher than the expenses of the Institutional Class Shares and, therefore, returns for the Class A Shares would be lower than those of the Institutional Class Shares. Institutional Class Shares performance presented has been adjusted to reflect the Distribution (12b-1) fees and, for the performance table, the Maximum Sales Charge (Load), applicable to Class A Shares. Institutional Class Shares first became available on April 25, 2008, when the Fund succeeded to the assets and operations of a common trust fund that was managed by The Frost National Bank (the "Predecessor Fund"). The performance information provided includes the returns of the Predecessor Fund for periods prior to April 25, 2008. Because the Predecessor Fund was not a registered mutual fund, it was not subject to the same investment and tax restrictions as the Fund; if it had been, the Predecessor Fund's performance may have been lower. Although the Predecessor Fund commenced operations prior to the periods shown, the earliest date for which its performance can be calculated applying the relevant performance standards is May 31, 2002 ("Performance Start Date"). The bar chart figures do not include sales charges that may have been paid when investors bought and sold Class A Shares of the Fund. If sales charges were included, the returns would be lower. Prior to February 1, 2010, the Fund employed a different investment strategy and, prior to June 29, 2010, the Fund was managed by a different sub-adviser. Therefore, the past performance shown below may have differed had the Fund's current investment strategy been in effect and had the current sub-advisers been managing the Fund. Of course, the Fund's past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Updated performance information is available on the Fund's website at www.frostbank.com or by calling 1-877-71-FROST.
