Marsh & McLennan Companies Retirement Plan

The plan is overseen by the board of directors of Marsh McLennan (now Marsh), chaired independently by H. Edward Hanway. Day-to-day investment management is directed by the plan's internal team, with subsidiary Mercer providing investment consulting, asset-liability modeling, and manager selection advice. This gives Mercer a dual role as both a third-party advisor and an affiliated entity within the same consolidated group.

Mercer is a wholly owned subsidiary of Marsh and serves as the plan's outsourced investment consultant. That creates a closed-loop model where the plan sponsor, the consultant, and the actuary all sit within the same corporate family. The arrangement gives the plan access to Mercer's global research and $15 trillion-plus advised client asset base, but it also concentrates fiduciary risk inside a single balance sheet.

Yes — the plan's trust maintains direct allocations to private equity and a separately managed global real estate portfolio of mixed-use properties. Those holdings sit alongside traditional public equities and fixed income, creating a diversified fund structure typical of large corporate defined-benefit plans. Specific fund commitments and co-investments are not publicly itemized.

The Marsh & McLennan Master Retirement Trust is a pooled investment vehicle that aggregates retirement plan assets from across the parent company's entities. The Marsh & McLennan Companies Retirement Plan is a participant in that trust, which allows multiple operating subsidiaries' pension obligations to share a common governance framework, fee structure, and investment policy statement.

CEO John Q. Doyle sits on the board of the Partnership for New York City — a network that includes prominent private equity and hedge fund managers — and co-chairs the International Advisory Board of BritishAmerican Business. Those roles embed the firm's leadership in the same circles frequented by institutional asset managers and large family offices, though the plan does not market externally for co-investors.

No. The Marsh & McLennan Companies Retirement Plan is a closed, single-sponsor defined-benefit plan for employees and retirees of the parent company. It does not accept capital from external institutional investors or high-net-worth individuals. Its club affiliations, such as CIEBA, serve peer-exchange and best-practice functions rather than capital-raising.

The primary structural risk is concentration: plan sponsor, investment consultant, and actuary all belong to the same corporate entity. In a distress scenario affecting the parent company — Marsh — the plan's funding health, advisory relationship, and corporate cash flow would be simultaneously stressed. The governance firewall between the independent board chair and the CEO is the key safeguard.
