This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover
Portfolio Turnover [Text Block] 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 30% of the average value of its portfolio.

Expense Example Narrative [Text Block] 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.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal market conditions, the Fund invests primarily in securities of companies listed on U.S. stock exchanges.  Investments consist primarily of common stocks of companies of any capitalization range.  The Fund may also invest in preferred stocks, warrants, options, and other equity-like instruments, such as partnership interests, limited liability company interests, business trust shares and rights and other securities that are convertible into equity securities. Additionally, the Fund may participate in securities lending arrangements up to 33-1/3% of the securities in its portfolio with brokers, dealers and financial institutions (but not individuals) in order to increase the return on its portfolio.

The Advisor seeks to find companies whose valuations in the market are modest and that earn higher than average returns on shareholders’ equity; are managed, in the Advisor’s judgment, by individuals who have a history of treating public shareholders like partners; and have ample opportunity to reinvest excess profits at above-average rates.  Once a potential investment is identified, the Advisor attempts to purchase shares at valuations the Advisor considers modest-to-reasonable, relative to the nature of the business, and the expected growth in economic value per share.  The Fund is non-diversified under the Investment Company Act of 1940, as amended (the “1940 Act”), and may invest a larger percentage of its assets in fewer issuers than diversified mutual funds.

The Advisor may sell a security for a variety of reasons, including, without limitation:  (1) a security subsequently fails to meet the Advisor’s initial investment criteria; (2) an issuer specific event, such as an acquisition or recapitalization that changes the fundamental operations of the company; (3) upon comparative analysis, a new security is judged more attractive than a current holding; or (4) views change of the individual holdings as well as the general market.
Risk [Heading] rr_RiskHeading Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
As with all mutual funds, there is the risk that you could lose all or a portion of your investment in the Fund.  The following are the principal risks that could affect the value of your investment:

·
General Market Risk – The market price of a security may fluctuate, sometimes rapidly and unpredictably.  These fluctuations may cause a security to be worth less than its cost when originally purchased or less than it was worth at an earlier time.

·
Equity Risk – Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value.

·
Mid-Cap and Small-Cap Investment Risk – Securities of mid-cap and small-cap companies may possess comparatively greater price volatility and less liquidity than the securities of companies that have larger market capitalizations and/or that are traded on major stock exchanges.

·
Non-Diversification Risk – The Fund is classified as “non-diversified,” which means the Fund may invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund.  Investment in securities of a limited number of issuers exposes the Fund to greater market risk and potential losses than if its assets were diversified among the securities of a greater number of issuers.

·
Management Risk – The Fund may not meet its investment objective based on the Advisor’s success or failure to implement investment strategies for the Fund.

·
Regulatory Risk – Changes in government regulations may adversely affect the value of a security.

·
Securities Lending Risk – There are certain risks associated with securities lending, including the risk that when lending portfolio securities, the securities may not be available to the Fund on a timely basis and the Fund may, therefore, lose the opportunity to sell the securities at a desirable price.
Risk Lose Money [Text] rr_RiskLoseMoney As with all mutual funds, there is the risk that you could lose all or a portion of your investment in the Fund.
Risk Nondiversified Status [Text] rr_RiskNondiversifiedStatus The Fund is classified as "non-diversified," which means the Fund may invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund. Investment in securities of a limited number of issuers exposes the Fund to greater market risk and potential losses than if its assets were diversified among the securities of a greater number of issuers.
