[1] Until February 28, 2027, Russell Investment Management, LLC has entered into a contractual fee waiver agreement that results in an effective advisory fee not to exceed 0.456%. This waiver may not be terminated during the relevant period except with Board approval. Until February 28, 2027, Russell Investments Fund Services, LLC has contractually agreed to waive 0.17% of its transfer agency fees for Class M Shares, 0.12% of its transfer agency fees for Class A, Class C and Class S 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. “Less Fee Waivers and Expense Reimbursements” and “Net Annual Fund Operating Expenses” have been restated to adjust for waivers that were implemented during the fiscal period ended October 31, 2025 but did not reflect a full year of waiver. “Other Expenses” for Class R6 Shares are based on estimated amounts for the current fiscal year as this Share Class did not have any assets during the most recent fiscal year.
