The fund's investment adviser has contractually agreed to limit the fund's total operating expenses (excluding certain expenses, such as front-end or contingent deferred sales charges, taxes (federal, state or otherwise), tax reclaim expenses, leverage and borrowing expenses (such as commitment, amendment and renewal expenses on credit or redemption facilities), interest, brokerage commissions, depositary receipt program fees, expenses incurred in connection with any merger or reorganization, expenses incurred in connection with any meeting of the fund's shareholders, unusual or infrequently occurring expenses, litigation expenses (including expenses for responding to document requests for litigation to which the fund is not a party), acquired fund fees and expenses, and dividend expenses, if any) so that such expenses do not exceed 0.76% for Institutional Class Shares and 0.68% for Class R6 Shares through October 31, 2027. Prior to October 31, 2027, only the fund's Board may modify or terminate the expense limitation agreement. Following the contractual period, the adviser may discontinue these expense reimbursement arrangements at any time. Under certain conditions, the adviser may recapture operating expenses reimbursed and/or fees waived under these arrangements for a period of three years following the date such waiver or reimbursement occurred, provided that the recapture does not cause the fund to exceed its expense limit in effect at the time of the waiver or reimbursement, and any in effect at the time of recapture, after repayment is taken into account.

The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance.
