Under the expense limitation agreement, the Adviser may recoup waived and/or reimbursed amounts with respect to the Fund within thirty‑six months of the date such amounts were waived or reimbursed, provided the Fund’s total annual operating expenses, including such recoupment, do not exceed the Expense Cap in effect at the time of such waiver/reimbursement.
