Clawback policies:

Investment Implications
- Alignment: High variable pay (average ~83% for NEOs) tied to adjusted EPS growth and relative TSR, plus significant unearned PSUs and option overhang, suggests strong pay-for-performance alignment; senior executive ownership guidelines (3x salary for Mr. South) and holding requirements increase alignment and reduce short-term selling .
- Retention risk: Double-trigger protections and uniform 1x severance multiples (no gross-ups) provide stability without excessive parachute incentives; restrictive covenants (12 months) add retention/transition discipline .
- Selling pressure: Hedging/pledging prohibitions and mandatory holding until guideline compliance, combined with scheduled vesting (options 2025–2028; PSUs 2027), mitigate opportunistic selling; any sales are subject to insider trading pre-clearance .
- Performance signals: 2024 bonus paid at 185% of target for Mr. South reflects strong Marsh and company results; PSU frameworks (target 8% three-year EPS growth with TSR modifier) continue to emphasize multi-year value creation with payouts capped at 200% .
Say-on-pay support was 93% in 2024, indicating stockholder endorsement of the executive compensation program design and outcomes .
