1 Nationwide Mutual Funds (the “Trust”) and Nationwide Fund Advisors (the “Adviser”) have entered into a written contract limiting annual fund operating expenses to 0.70% until at least March 31, 2017. Under the expense limitation agreement, the level to which operating expenses are limited applies to all share classes, excluding any taxes, interest, brokerage commissions, Rule 12b-1 fees, acquired fund fees and expenses, short-sale dividend expenses, administrative services fees, other expenses which are capitalized in accordance with generally accepted accounting principles and expenses incurred by the Fund in connection with any merger or reorganization, and may exclude other non-routine expenses not incurred in the ordinary course of the Fund’s business. The expense limitation agreement may be changed or eliminated only with the consent of the Board of Trustees of the Trust. The Trust is authorized to reimburse the Adviser for management fees previously waived and/or for expenses previously paid by the Adviser, provided, however, that any reimbursements must be paid at a date not more than three years after the fiscal year in which the Adviser waived the fees or reimbursed the expenses and the reimbursements do not cause the Fund to exceed the expense limitation that was in place at the time the Adviser waived the fees or reimbursed the expenses, or the current expense limitation, if different. More information about administrative services fees can be found in “Investing with Nationwide Funds” on pages 73-74 of the Prospectus.
