[1] The investment adviser has contractually agreed to waive management fees or reimburse expenses if Total Annual Fund Operating Expenses of any Class exceed 0.20% of the Class's average daily net assets, excluding Distribution and Service (12b-1) Fees, Shareholder Services Fees, brokerage expenses, taxes, dividend interest on short sales, interest expenses, and any extraordinary expenses, including litigation costs (the “Expense Limit”). The agreement’s current term ends on April 30, 2027, and automatically renews for one-year terms unless it is terminated upon termination of the investment advisory agreement or by Empower Funds or the investment adviser upon written notice within 90 days of the end of the current term. Under the agreement, the investment adviser may recoup, subject to the approval of the Board of Directors of Empower Funds, these waivers and reimbursements in future periods, not exceeding three years following the particular waiver/reimbursement, provided Total Annual Fund Operating Expenses of the Class plus such recoupment do not exceed the lesser of the Expense Limit that was in place at the time of the waiver/reimbursement or the Expense Limit in place at the time of recoupment.
