[1] Wasatch Advisors LP, doing business as Wasatch Global Investors (Advisor), the Fund’s investment advisor, has contractually agreed to waive fees and/or reimburse the Investor Class shares and Institutional Class shares of the Fund for Total Annual Fund Operating Expenses in excess of 1.00% and 0.85%, respectively, of average daily net assets until at least January 31, 2027, excluding fees and expenses incurred in borrowing securities and selling portfolio securities short including enhanced custody fees (which include borrowing costs, financing fees and other charges paid in connection with borrowing the security to be sold short and maintaining related margin collateral) and dividend expense on short sales/interest expense, acquired fund fees and expenses, interest, liquidity program service fees, taxes, brokerage commissions, other investment related costs, and extraordinary expenses such as litigation and other expenses not incurred in the ordinary course of business. The Fund may only make repayments to the Advisor for amounts reimbursed if such repayment does not cause the Fund’s expense ratio, after the repayment is taken into account, to exceed both (i) the expense cap in place at the time such amounts were waived; and (ii) the Fund’s current expense cap. Such repayment can be made until the expiration of the current contract, but in no case beyond three years from the date of such waiver or reimbursement by the Advisor. The Board of Trustees is the only party that can terminate the contractual limitation prior to the contract’s expiration. The Advisor can rescind the contractual limitation on expenses at any time after its expiration date. Shareholder expenses will increase if the Advisor does not renew the contractual expense cap after its expiration date.
