Berkshire Hathaway Specialty Insurance vs Marsh McLennan Agency

BHSI’s U.S. At A Glance section (version 2026-8-03 A) lists commercial property, casualty, healthcare professional liability, executive and professional lines, surety, travel, programs, employer stop loss, and homeowners insurance. The guide is informational, not policy coverage, and its brand-level list does not identify the insurer on a particular policy. ^1,2,5Company-reported. A description of BHSI's U.S. line list in its U.S. At A Glance section (version 2026-8-03 A) only. The guide says its descriptions are informational and are not coverage; its brand-level list does not assign an issuing insurer to a particular product or policy. This is not a claim that one legal insurer issues every BHSI product.

Berkshire Hathaway Specialty Insurance Company (BHSIC) identifies itself in its Singapore-branch public disclosure as a Nebraska-domiciled direct property and casualty insurer, wholly owned by National Indemnity Company, which is wholly owned by Berkshire Hathaway Incorporated. The Singapore-branch disclosure states this ownership chain. A Missouri Department of Insurance record separately lists BHSIC as active, NAIC 22276, and Property and Casualty in Missouri. Neither source identifies BHSIC as the issuer of every BHSI-branded U.S. policy. ^3,4,5Company-reported. Company-reported corporate identity and ownership in BHSI's Singapore-branch public disclosure, corroborated for company identity and Missouri P&C authority by the Missouri Department of Insurance record accessed 2026-09-28. Neither source maps BHSIC as issuer for every BHSI-branded U.S. product; use policy-specific documents for that.

As of 2026-09-28, Marsh’s US legal-entity page lists Marsh & McLennan Agency LLC as the current entity name for Marsh Agency (formerly MMA) and Marsh Agency LLC as proposed, with displayed state completion statuses marked TBD. Louisiana’s regulator lists Marsh & McLennan Agency LLC as a producer agency with active casualty, accident and health or sickness, life, property, and surplus-lines authorities through 2028-03-31. This is Louisiana-specific producer evidence, not evidence of an insurer role or nationwide licensing. ^34,25Verified. Current entity name and proposed legal-name transition as listed on Marsh’s US legal-entity page, plus producer-authority evidence for Louisiana only, accessed 2026-09-28. No other state licensing was audited; this record does not establish an insurer or underwriting role.

Marsh McLennan Agency describes itself as a business of Marsh and lists business insurance, employee health and benefits, retirement and wealth, and private-client insurance services across the United States and Canada. ²⁶Company-reported. Current MMA company description. Does not establish corporate ownership structure, the legal entity for a particular placement, or an insurer role.

BHSI's U.S. industry focus spans real estate, public entities, financial institutions, healthcare, education, manufacturing, retail, logistics, transportation, energy, and technology. The at-a-glance guide associates these industries with particular product segments; it does not say every segment serves every listed industry. ¹Company-reported. Company-stated industry focus in the United States section of the At A Glance (U.S. section version 2026-8-03 A); industry lists are segment-specific, not a universal eligibility statement.

Within its U.S. executive-lines commercial and financial segment, BHSI lists publicly traded and large privately owned commercial firms; investment, money-center, national, and regional banks; asset managers; and insurance companies and brokerages. The size description applies to the commercial-firm entry, not every listed institution or all BHSI products. ¹Company-reported. Only the U.S. Executive Lines, Commercial & Financial segment, At A Glance p. 50. The “publicly traded and large privately owned” qualifier attaches to the Commercial Firms bullet only.

MMA describes Marsh Agency as a separate business unit serving as an advocate and broker for the middle market. ³⁷Company-reported. Company-stated role and customer focus for the future Marsh Agency operating brand; not a revenue, size, or eligibility threshold.

MMA’s US industry directory includes pages for construction, financial institutions, healthcare, manufacturing, real estate, and transportation and trucking. These are examples of stated sector focus, not a complete appetite or eligibility list. ³²Company-reported. Examples from MMA’s national US industry directory; the directory is evidence of stated sector focus, not a complete appetite or eligibility list.

BHSI's website terms say online application or quote submissions are informational and nonbinding; only contracted agents of the National Indemnity group may bind coverage, issue policies or certificates, or change coverage. Group companies' authority also varies by state, so the terms do not show that every application must begin through an agent. ⁵Company-reported. The website's own online submissions and binding authority described by BHSI's terms; not a statement about every product's intake process or a claim that purchase can be completed online.

MMA’s US small-business page lists general liability, commercial property, workers’ compensation, professional liability, commercial auto, and cyber liability, and invites buyers to call 833-256-4266 for a personalized quote. The page also contains a small-business specialist form, but its function and any online application, purchase, or binding route are not established by the page reviewed. ³⁹Company-reported. US small-business landing page only. The phone invitation does not establish quote speed, eligibility, online purchase or binding; the embedded specialist form's function was not established.

BHSI’s U.S. Claims Service Standards document (version US 2024-10-07A) says coverage issues or reservations are discussed directly with insureds, brokers, and relevant parties, and brokers and policyholders are kept involved during third-party settlement discussions. These are company-stated process standards, not measured claims outcomes. ⁸Company-reported. Company-stated U.S. claims-service standards in version US 2024-10-07A; accessed 2026-09-28. Process commitments are not evidence of measured service or outcomes.

BHSI's U.S. website terms and claims page reviewed on September 28, 2026 do not explain how commercial policy renewals are quoted or completed. The U.S. product directory opened for this correction displays category navigation, but it is not a review of the linked product pages. These limited checks do not establish that renewal support or a renewal route is unavailable. ^6,5,7Not found in reviewed sources. A narrowly scoped research gap in the opened U.S. website terms and claims page and the U.S. product-directory landing page, checked 2026-09-28. The directory landing page provides category navigation only; linked product pages and account-specific servicing routes were not reviewed for this claim. This does not mean BHSI lacks renewal support.

MMA says the Marsh Agency brand transition will not change clients’ account manager, team, or point of contact, and will not affect existing policies or programs; clients may see the legal-name change during renewals. This describes the rebrand transition, not MMA’s general renewal process. ³⁷Company-reported. Only the announced Marsh Agency rebrand and its stated effect on existing clients; this does not document MMA’s general renewal workflow, renewal service level, or policy terms.

MMA’s Tampa office page lists InsurLink for policy and endorsement access, CSR24 for certificates, carrier contact information for commercial and personal-lines claims, and a local-consultant contact route. ⁴¹Company-reported. Services and client tools listed on the Tampa, Florida office page only. The claims listing provides carrier contact information and does not establish that MMA adjusts claims.

For claims outside separate product-specific instructions, BHSI's U.S. claims page lists email, 24-hour toll-free, and postal reporting routes; several products have their own route. ⁷Company-reported. Claims-notice channels published on BHSI's U.S. claims page at review date; policy/product-specific directions govern and the general channels are not universal.

On its business-interruption page, MMA says it will advocate with insurers for clients if complex claim issues arise. This is a company-reported service statement; it does not establish claim outcomes or an adjusting/payment role. ²⁷Company-reported. Company-described support for complex claims in the business-income and contingent-business-interruption page context; not a promise of claim outcomes or evidence that MMA adjusts or pays claims.
