Report of Independent Accountants

To the Board of Trustees

Russell Investment Company

We have examined management's assertion, included in the accompanying Management Statement Regarding Compliance with Certain Provisions of the Investment Company Act of 1940, that Russell Investment Company (comprised of Conservative Strategy Fund, Moderate Strategy Fund, Balanced Strategy Fund, Aggressive Strategy Fund and Equity Aggressive Strategy Fund) (the "Company") (the "Company") complied with the requirements of subsections (b) and (c) of Rule 17f-2 under the Investment Company Act of 1940 ("the Act") (the "specified requirements") as of March 14, 2025. Russell Investment Company's management is responsible for its assertion and the Company's compliance with the specified requirements. Our responsibility is to express an opinion on management's assertion about the Company's compliance with the specified requirements based on our examination.

Our examination was conducted in accordance with attestation standards established by the American Institute of Certified Public Accountants. Those standards require that we plan and perform the examination to obtain reasonable assurance about whether management's assertion about compliance with the specified requirements is fairly stated, in all material respects. An examination involves performing procedures to obtain evidence about whether management's assertion is fairly stated in all material respects. The nature, timing and extent of the procedures selected depend on our judgment, including an assessment of the risks of material misstatement of management's assertion, whether due to fraud or error. We believe that the evidence we obtained is sufficient and appropriate to provide a reasonable basis for our opinion.

Included among our procedures were the following tests performed as of March 14, 2025, and with respect to agreement of security purchases and sales or maturities, for the period from October 31, 2024 (the date of our last examination), through March 14, 2025:

Confirmation of all securities held by the transfer agent;

Reconciliation of all such securities to the books and records of the Company and the transfer agent;

Our examination does not provide a legal determination on the Company's compliance with the specified requirements.

We are required to be independent and to meet our other ethical responsibilities in accordance with relevant ethical requirements related to the engagement.

In our opinion, management's assertion that Russell Investment Company complied with the requirements of subsections (b) and (c) of Rule 17f-2 of the Investment Company Act of 1940 as of March 14, 2025 with respect to securities reflected in the investment account of the Company is fairly stated, in all material respects.

This report is intended solely for the information and use of management and the Board of Trustees of Russell Investment Company and the Securities and Exchange Commission and is not intended to be and should not be used by anyone other than these specified parties.
