[1] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, costs of shareholder meetings, and extraordinary expenses) exceed 0.24% of the average daily net assets of the Fund. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser has contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the fees and expenses of the affiliated money market funds incurred by the Fund because of the Fund’s investment in such money market funds. These waivers are in effect through 6/30/28, at which time it will be determined whether such waivers will be renewed or revised. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.
