Portfolio Turnover: 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 10% of the average value of its portfolio.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Principal Investment Strategies: Fenimore Asset Management, Inc. ("Fenimore"), the investment advisor to the Fund, employs a "value approach" in making its common stock selections. This approach is based on Fenimore's belief that at any given point in time the stock price of a company may sell below the company's "true business worth". Factors considered in evaluating the true business worth include the company's current earnings and Fenimore's opinion as to its future earnings potential. After identifying a company whose securities are determined to have a favorable price-to-earnings relationship, Fenimore plans to invest in such securities until the "true business worth" nears the market price of the company's securities.

 

Generally, the Fund will attempt to remain fully invested in common stocks and securities that are convertible into common stocks, such as convertible bonds and convertible preferred stocks. The Fund may invest in the securities of issuers of all sizes and market capitalizations. The Fund may also invest in the securities of both domestic and foreign issuers and it may invest in shares of other investment companies, including exchange-traded funds ("ETFs").

Principal Risks:
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
  • Stock Market Risk - the value of stocks fluctuates in response to the activities of individual companies and general stock market and economic conditions. Stock prices may decline over short or extended periods of time. Stocks are more volatile and riskier than some other forms of investments.
  • Stock Selection Risk - the value stocks chosen for the Fund are subject to the risk that the market may never realize their intrinsic value or their prices may go down.
  • Small-Cap Risk - small capitalization companies may not have the size, resources or other assets of large capitalization companies.
  • Market Risk - the value of your investment will go up and down, which means that you could lose money.
  • Foreign Investment Risk - the Fund may invest in securities of foreign issuers that are traded in foreign markets or may be represented by American Depository Receipts that are traded in the United States. Investments in non-U.S. securities may involve additional risk including exchange rate fluctuation, political or economic instability, the imposition of exchange controls, expropriation, limited disclosure and illiquid markets.
  • Investment in Other Investment Companies Risk – the Fund may invest in shares of other investment companies, including ETFs. Shareholders of the Fund will indirectly be subject to the fees and expenses of the other investment companies in which the Fund invests. In addition, shareholders will be exposed to the investment risks associated with investments in other investment companies.

This approach is based on Fenimore's belief that at any given point in time the stock price of a company may sell below the company's "true business worth".

After identifying a company whose securities are determined to have a favorable price-to-earnings relationship, Fenimore plans to invest in such securities until the "true business worth" nears the market price of the company's securities.

 

Under normal market conditions the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in securities of small-cap companies. The Fund considers small-cap companies to be those issuers that, at the time of initial purchase, have a market capitalization that is within or below the range of companies in the Russell 2000 Index as of the latest reconstitution. As of May 31, 2017, the market capitalization range for the Russell 2000 Index was approximately $143.6 million to $4.4 billion.

 

The Fund may invest in securities of both domestic and foreign issuers and it may invest in shares of other investment companies, including exchange-traded funds ("ETFs"). The Fund's policy of investing at least 80% of its net assets in small-cap companies may only be changed upon 60 days prior notice to shareholders.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Principal Investment Strategies: Fenimore Asset Management, Inc. ("Fenimore"), the investment advisor to the Fund, employs a "value approach" in making its common stock selections. This approach is based on Fenimore's belief that at any given point in time the stock price of a company may sell below the company's "true business worth". Factors considered in evaluating the true business worth include the company's current earnings and Fenimore's opinion as to its future earnings potential. After identifying a company whose securities are determined to have a favorable price-to-earnings relationship, Fenimore plans to invest in such securities until the "true business worth" nears the market price of the company's securities.

 

Generally, the Fund will attempt to remain fully invested in common stocks and securities that are convertible into common stocks, such as convertible bonds and convertible preferred stocks. The Fund may invest in the securities of issuers of all sizes and market capitalizations. The Fund may also invest in the securities of both domestic and foreign issuers and it may invest in shares of other investment companies, including exchange-traded funds ("ETFs").
Risk [Heading] rr_RiskHeading

Principal Risks:
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
  • Stock Market Risk - the value of stocks fluctuates in response to the activities of individual companies and general stock market and economic conditions. Stock prices may decline over short or extended periods of time. Stocks are more volatile and riskier than some other forms of investments.
  • Stock Selection Risk - the value stocks chosen for the Fund are subject to the risk that the market may never realize their intrinsic value or their prices may go down.
  • Small-Cap Risk - small capitalization companies may not have the size, resources or other assets of large capitalization companies.
  • Market Risk - the value of your investment will go up and down, which means that you could lose money.
  • Foreign Investment Risk - the Fund may invest in securities of foreign issuers that are traded in foreign markets or may be represented by American Depository Receipts that are traded in the United States. Investments in non-U.S. securities may involve additional risk including exchange rate fluctuation, political or economic instability, the imposition of exchange controls, expropriation, limited disclosure and illiquid markets.
  • Investment in Other Investment Companies Risk – the Fund may invest in shares of other investment companies, including ETFs. Shareholders of the Fund will indirectly be subject to the fees and expenses of the other investment companies in which the Fund invests. In addition, shareholders will be exposed to the investment risks associated with investments in other investment companies.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

Annual Total Return: The Institutional Shares of the Fund are a recently established share class and therefore do not yet have their own full calendar year of performance history. The performance results shown are for the Investor shares which are not offered in this Prospectus. Investor Shares are subject to higher fees because of differences in the shareholder administrative services fees and certain other fees paid by each class. Institutional Shares and Investor Shares would have substantially similar performance results because the shares of each class are invested in the same portfolio securities of the Fund. Because of the difference in the level of fees paid by Investor Shares, the returns for the Investor Shares will be lower than the returns for Institutional Shares. The following bar chart and table show some indication of the risks of investing in the Fund. The bar chart shows changes in the Investor Shares performance from year to year. The table shows the Investor Shares average annual returns (before and after taxes) compared to those of the Russell MidCap Index, the Fund's primary benchmark index. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information may be obtained at the Fund's website www.famfunds.com.

This approach is based on Fenimore's belief that at any given point in time the stock price of a company may sell below the company's "true business worth".

After identifying a company whose securities are determined to have a favorable price-to-earnings relationship, Fenimore plans to invest in such securities until the "true business worth" nears the market price of the company's securities.

 

Under normal market conditions the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in securities of small-cap companies. The Fund considers small-cap companies to be those issuers that, at the time of initial purchase, have a market capitalization that is within or below the range of companies in the Russell 2000 Index as of the latest reconstitution. As of May 31, 2017, the market capitalization range for the Russell 2000 Index was approximately $143.6 million to $4.4 billion.

 

The Fund may invest in securities of both domestic and foreign issuers and it may invest in shares of other investment companies, including exchange-traded funds ("ETFs"). The Fund's policy of investing at least 80% of its net assets in smallcap companies may only be changed upon 60 days prior notice to shareholders.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

Annual Total Return:  The performance results shown below for the periods prior to January 1, 2016, the date of commencement of operations of the Institutional Shares for the Fund, are for a class of shares of the Fund that are not offered in this Prospectus, Investor Shares, which are subject to higher fees as a result of differences in the shareholder administrative services fees and certain other fees paid by each class.  Institutional Shares and Investor Shares would have substantially similar performance results because the shares of each class are invested in the same portfolio securities of the Fund.  Because of the difference in the level of fees paid by Investor Shares, the returns for the Investor Shares will be lower than the returns for Institutional Shares.  The following bar chart and table show some indication of the risks of investing in the Fund.  The bar chart and table show the Investor Shares performance for periods prior to January 1, 2016.  The table shows the average annual returns (before and after taxes) for the 1-year, 5-year and since inception periods ended December 31, 2017 and compared to those of the Russell 2000 Index, the Fund's primary benchmark.  The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.  Updated performance information may be obtained at the Fund's website famfunds.com.
