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 26% of the average value of its portfolio.

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 of non-U.S. issuers. This investment policy may be changed by the Fund upon 60 days' prior notice to shareholders. The Fund invests primarily in common stocks, but may also invest in other types of equity securities, such as preferred stock, convertible securities, warrants or other similar publicly traded securities. The Fund may also purchase American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs"). The Fund's investments are ordinarily diversified among regions, countries and currencies, as determined by its sub-adviser, Thornburg Investment Management Inc. ("Thornburg"). Thornburg intends to invest on an opportunistic basis when it believes there is intrinsic value. The Fund's principal focus will be on traditional or "basic" value stocks. However, the portfolio may include stocks that, in Thornburg's opinion, provide value in a broader or different context. The relative proportions of these different types of securities will vary over time. The Fund ordinarily invests in stocks that may be undervalued or reflect unfavorable market perceptions of company or industry fundamentals. The Fund may invest in companies of any size. Debt securities will be considered for investment when Thornburg believes them to be more attractive than equity alternatives. The Fund may purchase debt securities of any maturity and quality. The Fund evaluates currency risk on a stock-by-stock basis. The Fund will hedge currency exposure utilizing forward contracts if deemed appropriate by the portfolio management team. Currency hedging, if utilized, is to protect the investment thesis for a given stock from being significantly undermined by dollar/foreign currency fluctuations when we perceive currency risk to be high. Thornburg primarily uses individual company and industry analysis to make investment decisions. Value, for purposes of Thornburg's selection criteria, relates to both current and projected measures. Among the specific factors considered by Thornburg in identifying undervalued securities for inclusion in the Fund's portfolio are: o price/earnings ratio o price/book value o price/cash flow ratio o debt/capital ratio o dividend yield o security and consistency of revenue stream o undervalued assets o relative earnings growth potential o industry growth potential o industry leadership o dividend growth potential o franchise value o potential for favorable developments The Fund typically makes equity investments in the following three types of companies: o BASIC VALUE companies which, in Thornburg's opinion, are financially sound companies with well established businesses whose stock is selling at low valuations relative to the companies' net assets or potential earning power. o CONSISTENT EARNER companies when they are selling at valuations below historic norms. Stocks in this category sometimes sell at premium valuations and sometimes at discount valuations. Generally, they show steady earnings and dividend growth. o EMERGING FRANCHISES are value-priced companies that in Thornburg's opinion are in the process of establishing a leading position in a product, service or market and which Thornburg expects will grow, or continue to grow, at an above average rate. Under normal conditions, the proportion of the Fund invested in companies of this type will be less than the proportions of the Fund invested in basic value or consistent earner companies.
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. 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. When the Fund invests in foreign fixed income securities, it will be subject to risks not typically associated with domestic securities. Foreign investments, especially investments in emerging markets, can be riskier and more volatile than investments in the United States. Adverse political and economic developments or changes in the value of foreign currency can make it more difficult for the Fund to sell its securities and could reduce the value of your shares. Differences in tax and accounting standards and difficulties in obtaining information about foreign companies can negatively affect investment decisions. Unlike more established markets, emerging markets may have governments that are less stable, markets that are less liquid and economies that are less developed. EMERGING MARKET SECURITIES RISK -- Investments in emerging markets securities are considered speculative and subject to heightened risks in addition to the general risks of investing in non-U.S. securities. Unlike more established markets, emerging markets may have governments that are less stable, markets that are less liquid and economies that are less developed. In addition, emerging markets securities may be subject to smaller market capitalization of securities markets, which may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; and possible restrictions on repatriation of investment income and capital. Furthermore, foreign investors may be required to register the proceeds of sales, and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization or creation of government monopolies. FOREIGN CURRENCY RISK -- Because non-U.S. securities are usually denominated in currencies other than the dollar, the value of the Fund's portfolio may be influenced by currency exchange rates and exchange control regulations. The currencies of emerging market countries may experience significant declines against the U.S. dollar, and devaluation may occur subsequent to investments in these currencies by the Fund. Inflation and rapid fluctuations in inflation rates have had, and may continue to have, negative effects on the economies and securities markets of certain emerging market countries. HEDGING RISK -- The Fund may use forward currency contracts for hedging purposes. Hedging through the use of these instruments does not eliminate fluctuations in the underlying prices of the securities that the Fund owns or intends to purchase or sell. While entering into these instruments tends to reduce the risk of loss due to a decline in the value of the hedged asset, such instruments also limit any potential gain that may result from the increase in value of the asset. To the extent that the Fund engages in hedging strategies, there can be no assurance that such strategy will be effective or that there will be a hedge in place at any given time. INTEREST RATE RISK -- As with most funds that invest in debt securities, changes in interest rates are one of the most important factors that could affect the value of your investment. Rising interest rates tend to cause the prices of debt securities (especially those with longer maturities) and the Fund's share price to fall. Debt securities have a stated maturity date when the issuer must repay the principal amount of the bond. Some debt securities, known as callable bonds, may repay the principal earlier than the stated maturity date. Debt securities are most likely to be called when interest rates are falling because the issuer can refinance at a lower rate. Mutual funds that invest in debt securities have no real maturity. Instead, they calculate their weighted average maturity. This number is an average of the effective or anticipated maturity of each debt security held by the mutual fund, with the maturity of each security weighted by the percentage of its assets of the mutual fund it represents. CREDIT RISK -- The credit rating or financial condition of an issuer may affect the value of a debt security. Generally, the lower the quality rating of a security, the greater the risk that the issuer will fail to pay interest fully and return principal in a timely manner. If an issuer defaults or becomes unable to honor its financial obligations, the security may lose some or all of its value. The issuer of an investment-grade security is more likely to pay interest and repay principal than an issuer of a lower rated bond. Adverse economic conditions or changing circumstances, however, may weaken the capacity of the issuer to pay interest and repay principal. Although the Fund's U.S. government securities are considered to be among the safest investments, they are not guaranteed against price movements due to changing interest rates. Obligations issued by some U.S. government agencies are backed by the U.S. Treasury, while others are backed solely by the ability of the agency to borrow from the U.S. Treasury or by the government sponsored agency's own resources. As a result, investments in securities issued by government sponsored agencies that are not backed by the U.S. Treasury are subject to higher credit risk than those that are. High yield, or "junk," bonds are highly speculative securities that are usually issued by smaller less credit worthy and/or highly leveraged (indebted) companies. Compared with investment-grade bonds, high yield bonds carry a greater degree of risk and are less likely to make payments of interest and principal. Market developments and the financial and business conditions of the corporation issuing these securities influences their price and liquidity more than changes in interest rates, when compared to investment-grade debt securities. Insufficient liquidity in the junk bond market may make it more difficult to dispose of junk bonds and may cause the Fund to experience sudden and substantial price declines. A lack of reliable, objective data or market quotations may make it more difficult to value junk bonds accurately. INVESTMENT STYLE RISK -- The Fund pursues a "value style" of investing. Value investing focuses on companies with stocks that appear undervalued in light of factors such as the company's earnings, book value, revenues or cash flow. If Thornburg's assessment of a company's value or prospects for exceeding earnings expectations or market conditions is wrong, the Fund could suffer losses or produce poor performance relative to other funds. In addition, "value stocks" can continue to be undervalued by the market for long periods of time.

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 June 30, 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 and sub-advised by Thornburg and INVESCO Global Asset Management N.A. (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. 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.
