Each waiver or reimbursement of an expense by the Adviser is subject to repayment by the Fund within the three fiscal years following the date such waiver and/or reimbursement was made, provided that the Fund is able to make the repayment without exceeding the expense limitation in place at the time of the waiver or reimbursement and at the time the waiver or reimbursement is recouped. The Trust and the Adviser may terminate this expense limitation agreement prior to July 31, 2026 only by mutual written consent.

Expense Example Narrative [Text Block]

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. The effect of the Adviser’s agreement to waive fees and/or expenses is only reflected in the first year of the example shown. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover [Heading] Portfolio Turnover
Portfolio Turnover [Text Block]

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 the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 10.08% of the average value of its portfolio.
