Marsh vs USI Insurance Services

Marsh’s US compensation guide states that, as an insurance broker, Marsh’s role is to facilitate placement of insurance coverage on behalf of clients. The transparency page describes determining appropriate insurers and negotiating with those insurers. Marsh is not identified in these sources as the insurer that issues or pays the policy. ^18,17,2

Current Marsh materials use more than one US legal name. The compensation guide (copyright 2024, Marsh LLC) refers to Marsh LLC and Marsh USA LLC entering client agreements. The transparency page instead names Marsh LLC and Marsh USA Inc. Marsh McLennan Agency is described as a wholly owned Marsh subsidiary. A 2006 California decision caption used MARSH USA, INC., dba MARSH RISK AND INSURANCE SERVICES, license 0437153. Confirm the exact contracting producer on the proposal and license documents; current California license status remains unverified. ^{18,17,19,20,1,31}

USI describes itself as a U.S. insurance brokerage and consulting firm that arranges property and casualty, employee benefits, personal risk, program, and retirement solutions. The reviewed official pages do not identify USI as the insurer that issues commercial policies. ^34,33,40,53

USI’s commissions page states that, as a licensed insurance producer, it may advise on insurance contracts, sell insurance, and obtain coverages for clients. Privacy and staff materials identify the operating company as USI Insurance Services LLC. Current California producer-license status remains independently unverified. ^40,39,54

On 31 August 2026, Aon plc announced a definitive agreement to acquire USI from KKR and other shareholders for a $17.0 billion purchase price, with closing expected in the fourth quarter of 2026 subject to customary conditions including regulatory approvals. Aon stated that Aon and USI will continue to operate independently until the closing date. The reviewed announcement does not establish that the transaction has closed. ⁵³

Marsh describes itself as a global insurance broker and risk advisor. Its homepage says it advises clients in 130 countries across industries that include technology. US broking is organized in segments: Risk Management (including large, complex programs), Corporate (midsize domestic firms), Marsh McLennan Agency (middle-market companies in the United States and Canada), and Affinity programs. The Technology Practice is the industry team that markets data-center, fintech and digital-infrastructure work. Public pages do not publish a minimum premium, employee count or California-startup eligibility rule. ^1,3,18,20

USI says it has served over 500,000 clients nationwide and positions itself as a middle-market brokerage and consulting firm. Its Technology practice describes clients including software, hardware, networking, semiconductors, or communications companies from early seed stage through IPO. Public pages do not publish a minimum revenue, headcount, or California-startup eligibility screen. ^34,42,53

The public Marsh path to speak with a broker is an inquiry, not an online bind. Contact pages ask you to choose an inquiry type, including a sales or RFP route. The business-inquiry page says to complete a form and that a representative will respond within 48 hours; it points existing-policy certificate, billing and policy questions elsewhere. The inquiry page does not display premiums or bind coverage. The 48-hour response time is a company statement, not a binding or service guarantee. ^15,16,21

Marsh describes a broker-led placement: identifying insurers for the risk, negotiating coverage and price, and, in core US broking segments, disclosing quotes and premium indications received. It may share incumbent or competing insurer names, pricing objectives, expiring terms, or give an insurer a last look when it believes that is in the client’s interest or the client instructs it. Those market practices are disclosure statements, not a guaranteed outcome or turnaround. ^18,17

USI does not publish a self-serve commercial quote flow on the reviewed pages. Technology and P&C inquiries are directed to pcinquiries@usi.com or a local office. The contact page includes a website message box that USI warns is not secured in transit and should not be used for sensitive information. Small- and medium-sized management-liability inquiries are also directed to Select.Business@usi.com. No public binding timetable or online eligibility tool was found. ^42,41,37,49

Marsh’s US compensation guide says it may be paid by insurer retail commissions, client fees (often in a written Client Service Agreement, sometimes crediting commissions), wholesale commissions, insurer consulting compensation, supplemental commissions, compensation for facilities or other insurer arrangements, interest on premium accounts, and other benefits. Marsh says it does not accept contingent commissions on domestic placements for US clients in core broking operations, except for employee health and benefits or when acting as managing general agent or underwriting manager; Marsh McLennan Agency does accept contingent commissions. Standard public premium ranges or a startup fee schedule were not found. Request an account-specific disclosure of commissions, fees, contingent or supplemental amounts, premium finance charges and any affiliated-market compensation. ^18,17,30

Unless otherwise negotiated, USI says compensation for placing coverage is customarily a commission calculated as a percentage of premium and paid by the insurer. It may also receive additional monetary and non-monetary compensation from insurers or intermediaries (including affiliates), which can be contingent on volume, profitability, or other factors, and some agreements include growth or distribution incentives. Clients may request the nature and source of expected compensation, including on alternative quotes. Standard commission percentages and fee schedules for startup accounts are not published. ⁴⁰

Marsh’s Claims Management service describes acting as an advisor among the business, insurer and third-party administrator: preparing, presenting and negotiating claims. Its cyber claims-advocacy page says specialists review claims, support litigation management, develop proof of loss with forensic accountants and advocate with insurers. MMA similarly describes claims advocacy as a carrier liaison on cyber matters and as part of property and casualty service. These are descriptions of assistance. They do not establish that Marsh pays claims, that a claim will be covered, or that recovery amounts cited in marketing were independently checked. ^10,9,24,27

USI’s contact page tells people seeking claims assistance to contact the appropriate USI office. A May 2021 claims kit instructs clients to report property, workers’ compensation, general liability, and commercial auto claims to the insurance company, and to involve the USI account team or claims consultant for environmental, executive/management liability, professional liability/E&O, and cyber. Natural-disaster guidance likewise points commercial P&C clients to their claims representative or client service team. The materials describe reporting assistance, not claims-handling quality or authority to settle. ^37,51,52,41
