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 $100,000
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 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 5% of the average value of its portfolio.

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.

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 circumstances, the Fund invests at least 80% of its net assets in
full faith and credit U.S. Treasury obligations. This investment policy may be
changed by the Fund upon 60 days' prior notice to shareholders. In selecting
investments for the Fund, the Fund's sub-adviser, Kempner Capital Management,
Inc. ("KCM"), tries to increase income without adding undue risk by analyzing
yields. The Fund's investments include Treasury bonds, Treasury notes, Treasury
Inflated Protection Securities and short-term U.S. government money market
funds. In evaluating a security for the Fund's portfolio, KCM considers, among
other factors, the security's interest rate, yield and maturity. KCM actively
manages the maturity of the Fund and its portfolio to maximize the Fund's yield
based on current market interest rates and KCM's outlook on the market.

The Fund may invest in full faith and credit money market instruments.  The
percentage of the Fund invested in such holdings varies depending on various
factors, including market conditions. Consistent with preservation of capital,
a larger percentage of the Fund's net assets may be invested in cash or money
market instruments in order to provide capital and reduce the magnitude of loss
in a period of falling market prices.
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.

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. Rising interest rates may also cause investors to pay off
mortgage-backed and asset-backed securities later than anticipated, forcing the
Fund to keep its money invested at lower rates. Falling interest rates,
however, generally cause investors to pay off mortgage-backed and asset-backed
securities earlier than expected, forcing the Fund to reinvest the money at a
lower interest rate.

The concept of duration is useful in assessing the sensitivity of a fixed
income fund to interest rate movements, which are the main source of risk for
most fixed-income funds. Duration measures price volatility by estimating the
change in price of a debt security for a 1% change in its yield. For example,
a duration of five years means the price of a debt security will change about 5%
for every 1% change in its yield. Thus, the higher duration, the more volatile
the security.

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.
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.

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 year and since inception compare with those of a broad
measure of market performance.

Class A Shares of the Fund do not have a full calendar year of performance.
Consequently, the bar chart shows the performance of the Fund's Institutional
Class Shares from year to year and the performance table compares the average
annual total returns of the Fund's Institutional Class Shares to those of a
broad measure of market performance.  The Fund's Institutional Class Shares are
offered in a separate prospectus. Class A Shares of the Fund would have
substantially similar performance as Institutional Class 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 the 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 KCM (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 November 30, 2006 ("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.

Capital Treasury Bond 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.
