Marsh agreed to buy Wilshire, the investment consultant whose services span OCIO, analytics and indexes, adding $221 billion in assets under management and $1.6 trillion in assets under advisement. Financial terms were not disclosed.

The firms expect to close in the first quarter of 2027, subject to customary closing conditions, regulatory approvals and client consents, according to IREI. As Private Wealth Daily previously reported, those client consents give institutional clients a say before the deal completes. Wilshire's institutional roster includes the California Public Employees' Retirement System, the Ohio Police & Fire Pension Fund, the Illinois Municipal Retirement Fund and the Kentucky Public Pensions Authority, PLANADVISER reported.

Plan sponsors using Wilshire for consulting or OCIO will be asked to consent before the deal closes, IREI reports. It was not specified whether the consent covers the consulting contract, the discretionary mandate, or both. Advisors bidding for institutional mandates will face a competitor carrying Wilshire's analytics, index business and $1.6 trillion advisory footprint inside a larger firm.

Wilshire's consulting, OCIO, asset management, analytics and index staff in the United States, Europe and Asia will join Marsh on completion, PLANADVISER reported.
