Fee waivers and expense reimbursements are subject to possible recoupment by the adviser from the Fund in future years on a rolling three-year basis (within the three years after the fees have been waived or reimbursed) if, after the recoupment is taken into account, such recoupment can be achieved within the lesser of the expense limitation in place at the time of waiver/reimbursement and the expense limitation in place at the time of recapture.

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

Expense Example by, Year, Caption [Text] The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then hold or redeem all of your shares at the end of those periods. The Example only accounts for the Fund’s expense limitation in place through its expiration period, October 31, 2026, and then depicts the Fund’s total annual expenses thereafter. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 annual fund operating expenses or in the Example, affect the Fund’s performance. The portfolio turnover rate of the Fund for the fiscal year ended June 30, 2025, was 126% of the average value of its portfolio.
