AIG vs THREE by Berkshire Hathaway: How Do They Compare for Commercial Property Insurance?

AIG markets commercial property insurance and identifies Retail Property as a product area. For domestic and global corporate and risk-management clients, the page describes both risk-transfer insurance and non-risk-transfer fronting or captive solutions; those structures are not the same as an insurance policy issued by AIG. ³Company-reported. AIG’s U.S. Commercial Property page. It does not identify the insurer or fronting company for a particular buyer’s placement.

THREE presents Property as a component of its combined Business Owners Policy rather than identifying it as a separate standalone policy on the reviewed product page. ⁶Company-reported. Company-described U.S. package structure. The page does not establish underwriting terms or that every listed category will be included for every applicant.

The linked sample policy's declarations identify Berkshire Hathaway Direct Insurance Company as issuer. ⁵Company-reported. This is the issuer named on the public sample only; the sample does not establish the issuing entity for every state-specific quote or buyer's issued policy.

AIG names businesses including hospitals, universities and global manufacturing among the varied organizations for which it has property options. The page does not provide a complete eligible-class list or state-by-state availability schedule. ³Company-reported. Illustrative customer types on AIG’s U.S. Commercial Property page; examples do not establish an applicant’s eligibility.

The reviewed product page does not state separate eligibility rules for Property; the general quote and advisor route is not proof that a particular business qualifies for it. ^6,4Not publicly disclosed. Eligibility and state availability remain unestablished for an individual risk until THREE returns its quote and applicable forms.

AIG describes commercial property insurance as protecting business physical property against unexpected events such as storm damage, theft and vandalism, and says coverage can extend to certain work-related contents such as office equipment, furniture, fixtures and inventory. These are examples; actual coverage depends on the facts and each policy’s terms, conditions and exclusions. ³Company-reported. General property description on AIG’s product page, not a summary of a specific policy or all covered causes of loss.

THREE's Business Owners Policy page lists Property among its marketed coverage categories in the combined policy. This describes the product page, not whether the category appears in a particular quote or responds to a loss. ^6,5Company-reported. Official THREE package marketing for Property. The sample policy is state-selectable and does not establish that this item is included in every quote or issued policy.

The reviewed public product page does not state a separate limit or deductible for Property; THREE says the quote-specific insurance summary lists limits and deductibles. ^6,5Not publicly disclosed.

AIG says property risk engineers help clients identify and mitigate loss and that its engineers collaborate with clients on solutions tailored to risk factors. The page does not state that these services are included for every account or guarantee reduced losses. ³Company-reported.
