Financial Analyst

TL;DR: Director received routine RSU awards, a modest increase in reported beneficial ownership; this is a standard, non-economic compensation event.

The transactions recorded on 08/15/2025 reflect issuance of restricted stock units under the Marsh & McLennan Directors Stock Compensation Plan: 198.26 units from director fees and 373.86 units credited as dividend equivalents. These convert 1-for-1 into common shares; the filing lists post-transaction beneficial ownership levels of 86,624.11 and 86,997.97 respectively. There is no exercise price, sale, or cash proceeds reported, and no derivative transactions disclosed.

Corporate Governance Expert

TL;DR: This Form 4 documents routine director compensation in equity form and appears to comply with standard disclosure requirements.

The reporting clarifies the nature of the awards: conversion ratio (1-for-1), awards from director fees, and dividend equivalents credited under the Directors Stock Compensation Plan. Signature by an attorney-in-fact is provided. The filing does not disclose any unusual arrangements, sales, or transfers by the director. From a governance perspective, the disclosure is consistent with typical equity grant reporting for non-employee directors and provides visible tracking of beneficial ownership changes.
