Marsh McLennan Agency (MMA), Marsh's middle-market subsidiary, arranges surety bonds through a dedicated surety practice rather than underwriting them itself. ⁵Company-reported. MMA surety insurance page.

Under WTW's North American Corporate Risk & Broking terms, WTW normally acts as the client's insurance intermediary for engagements governed by those terms. ¹¹Company-reported. Terms for applicable North American Corporate Risk & Broking engagements. WTW also discloses separate insurer-side services in some arrangements; this does not determine the role in a specific engagement.

The reviewed page does not name a specific surety insurer for a standard bond; MMA says it offers national market representation, implying the issuing surety varies by placement. ⁵Not publicly disclosed. MMA surety insurance page as read on 2026-09-23.

The reviewed WTW sources do not identify an issuing insurer for a specific surety bonds placement. ^11,10Not publicly disclosed. This is a gap in the cited marketing, annual-report, and brokerage materials; it does not mean WTW lacks insurer markets. Confirm the carrier on the quote and issued policy.

MMA offers Contract Surety for construction and similar projects, Commercial Surety issuing license and permit bonds nationwide (in lieu of or alongside letters of credit and other banking obligations), and International Surety for global operations facing varied regulatory requirements. ⁵Company-reported.

MMA lists competitive indemnity package negotiation, industry benchmarking, joint-venture and teaming-agreement prequalification support, continuity and ownership-transfer consulting, and competitive program design review as services tied to its surety practice. ⁵Company-reported.
