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 annual fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 39.50% of the average value of its portfolio.

Expense Example, Heading	rr_ExpenseExampleHeading	Example.
Expense Example, Narrative	rr_ExpenseExampleNarrativeTextBlock	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 (taking into account the Expense Cap only in the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Investment Strategy, Heading	rr_StrategyHeading	Principal Investment Strategies of the Fund
Investment Strategy, Narrative	rr_StrategyNarrativeTextBlock	The Advisor uses a disciplined approach to select stocks for the Fund's portfolio that it believes are undervalued and have prospects for continued consistent growth. The Advisor uses fundamental analysis of financial statements to select stocks of issuers that generally have low price/earnings and price/book ratios as well as strong balance sheet ratios and high and/or stable dividend yields. The Fund invests primarily in large, well-recognized companies. Currently, the Advisor expects the Fund's portfolio to hold at least 20% of the stocks comprising the Standard & Poor's 100 Index, a capitalization-weighted index of 100 stocks from a broad range of industries. Normally, the Fund will invest at least 85% of its total assets in equity securities, consisting of common stocks and securities having the characteristics of common stocks, such as convertible securities, exchange-traded funds ("ETFs"), rights and warrants. The Advisor may choose to sell a security when it believes the security no longer offers attractive returns or when the Advisor wishes to take advantage of a better investment opportunity.
Risk, Heading	rr_RiskHeading	Principal Investment Risks
Risk, Narrative	rr_RiskNarrativeTextBlock	By itself, the Fund is not a complete, balanced investment plan. The Fund cannot guarantee that it will achieve its investment objectives. You may lose money by investing in the Fund. The Fund is subject to the following principal risks: Management Risk. The skill of the Advisor will play a significant role in the Fund's ability to achieve its investment objectives. Equity Market Risk. The value of the Fund's shares will go up or down based on the movement of the overall stock market and the value of the individual securities held by the Fund, both of which can sometimes be volatile.    Sector Risk. Sector risk is the possibility that investments within the same economic sector will decline in price due to sector-specific market or economic developments. Value Style Risk. "Value" investing as a strategy may be out of favor in the market for an extended period. Value stocks can perform differently from the market as a whole and from other types of stocks.

[1] The Edgar Lomax Company (the "Advisor") has contractually agreed to waive all or a portion of its management fees and pay expenses of the Fund to ensure that Net Annual Fund Operating Expenses (excluding acquired fund fees and expenses ("AFFE"), interest, taxes and extraordinary expenses) do not exceed 0.99% of the Fund's average daily net assets (the "Expense Cap"). The Expense Cap will remain in effect through at least February 28, 2013, and may be terminated only by the Trust's Board of Trustees (the "Board"). The Advisor may request recoupment of previously waived fees and paid expenses from the Fund for three years from the date they were waived or paid, subject to the Expense Cap. In addition, the Advisor has voluntarily agreed to waive a portion of its management fee contingent upon the Fund's performance versus the S&P 500/Citigroup Value Index ("Citigroup Value"), the S&P 500's "value" style index. If the Advisor waives management fees under this arrangement, it has also agreed to absorb all expenses, other than management fees (categorized as "Other Expenses" in the table). The Advisor has agreed to continue this waiver arrangement through at least February 28, 2013. While this waiver arrangement may be discontinued at any time after February 28, 2013, the Advisor has no intention of doing so. For more information, please see the "Management Fee and Voluntary Fee Waiver" section in the statutory prospectus.
