Expense, Heading	rr_ExpenseHeading	FUND FEES AND EXPENSES
Expense, Narrative	rr_ExpenseNarrativeTextBlock	The table below describes the fees and expenses that you may pay if you buy and hold Institutional Class Shares of the Fund.
Operating Expenses, Caption	rr_OperatingExpensesCaption	ANNUAL FUND OPERATING EXPENSES (EXPENSES THAT YOU PAY EACH YEAR AS A PERCENTAGE OF THE VALUE OF YOUR INVESTMENT)
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 12% of the average value of its portfolio.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same.

Investment Strategy, Heading	rr_StrategyHeading	PRINCIPAL INVESTMENT STRATEGIES
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Fund invests at least 80% of its net assets in equity securities. This investment policy may be changed by the Fund upon 60 days' prior notice to shareholders. The equity securities in which the Fund may invest include common stocks, preferred stocks, convertible securities, rights and warrants. The Fund may invest in companies of all market capitalizations. The Fund intends to invest in companies that the Fund's sub-adviser, Luther King Capital Management Corporation ("LKCM"), believes are likely to have above-average growth in revenue, above-average earnings, above-average returns on shareholders' equity, underleveraged balanced sheets and/or the potential for above-average capital appreciation. In selecting investments for the Fund, LKCM performs analyses of financial and fundamental criteria to identify high-quality companies, focusing on the following characteristics: o Consistently high profitability; o Strong balance sheets; o Competitive advantages; o High and/or improving financial returns; o Free cash flow; o Reinvestment opportunities; and o Prominent market share positions.
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. 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- AND MID-CAPITALIZATION COMPANY RISK -- The small- and mid-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- and mid-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- and mid-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 purchasing 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.
Risk, Lose Money	rr_RiskLoseMoney	As with all mutual funds, a shareholder is subject to the risk that his or her investment could lose money.
Risk, Not Insured Depository Institution	rr_RiskNotInsuredDepositoryInstitution	A FUND SHARE IS NOT A BANK DEPOSIT AND IT IS NOT INSURED OR GUARANTEED BY THE FDIC, OR ANY GOVERNMENT AGENCY.
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 Fund commenced operations after succeeding to the assets and operations of a common trust fund that was managed by The Frost National Bank and sub-advised by LKCM (the "Predecessor Fund"). The performance information provided includes the returns of the Predecessor Fund for periods prior to April 25, 2008 and has been adjusted to reflect expenses for Institutional Class Shares of the Fund. 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 the Predecessor Fund's performance can be calculated applying the relevant performance standards is July 31, 2002 ("Performance Start Date"). 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.

Performance Table, Narrative	rr_PerformanceTableNarrativeTextBlock	This table compares the Fund's Institutional Class Shares' average annual total returns for the periods ended December 31, 2010 to those of the S&P 500 Index. After-tax returns cannot be calculated for periods before the Fund's registration as a mutual fund and they are, therefore, unavailable for the period since the Performance Start Date. After-tax returns 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 will depend on an investor's tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.
