[1] Until February 28, 2027, Russell Investment Management, LLC has contractually agreed to waive up to the full amount of its advisory fee and then to reimburse the Fund for other direct Fund-level expenses to the extent such direct Fund-level expenses exceed 0.64% of the average daily net assets of the Fund on an annual basis. This waiver and reimbursement may not be terminated during the relevant period except with Board approval. Direct Fund-level expenses do not include Rule 12b-1 distribution fees, shareholder services fees, transfer agency fees, foreign tax reclaim related expenses, infrequent and/or unusual expenses (including litigation expenses) or the expenses of other investment companies in which the Fund invests which are borne indirectly by the Fund. Until February 28, 2027, Russell Investments Fund Services, LLC has contractually agreed to waive 0.15% of its transfer agency fees for Class M Shares and 0.02% of its transfer agency fees for Class R6 Shares. These waivers may not be terminated during the relevant period except with Board approval. “Other Expenses” for Class A and Class C Shares are based on estimated amounts for the current fiscal year as these Share Classes did not have any assets during the most recent fiscal year. “Other Expenses,” “Total Annual Fund Operating Expenses” and “Net Annual Fund Operating Expenses” have been restated to reflect expenses expected to be incurred by the Fund.
