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 438.73% of the average value of its portfolio

[1] "Interest and Dividends on Securities Sold Short" reflects interest expense and dividends paid on borrowed securities. Interest expense results from the Fund's use of prime brokerage arrangements to execute short sales. Dividends paid on borrowed securities are an expense of short sales. Such expenses are required to be treated as a Fund expense for accounting purposes and are not payable to the Fund or the Advisor. Any interest expense amount or dividends paid on securities sold short will vary based on the Fund's use of those investments.
[2] The Advisor has entered into an Expense Limitation Agreement with the Fund under which it has agreed to waive or reduce its fees in an amount that limits the Fund's annual operating expenses (exclusive of acquired fund fees and expenses, interest, taxes, brokerage fees and commissions, extraordinary expenses, and payments under the Rule 12b-1 distribution plan) to not more than 1.70% of the average daily net assets of the Fund through September 30, 2018 . The Expense Limitation Agreement may not be terminated prior to that date. Further, net annual operating expenses for the Fund may exceed those contemplated by the waiver due to acquired fund fees and other expenses that are not waived under the Expense Limitation Agreement.
[3] It should be noted that the performance reflected above reflects that of the prior investment advisor, Caritas Capital, LLC. The Fund's current advisor, Goodwood Advisors, LLC, assumed responsibility of fund operations on October 31, 2013. Advisor Class shares commenced operations on January 4, 2010. Institutional Class shares commenced operations on July 16, 2014. The annual returns would differ only to the extent that the Classes have different expenses .
