What Is AIG?
AIG is the marketing name for American International Group, Inc.; AIG says its insurance products are written or provided by subsidiaries or affiliates. Its U.S. business pages list commercial casualty, property, cyber, management and professional liability, and specialty programs, but a brand-level page does not identify the insurer for a particular policy. 1,2
What Is Berkshire Hathaway Specialty Insurance?

What Is Commercial Property Insurance?
Commercial property may fit your business if you own a building or rely on equipment and stock. Compare replacement-cost terms, deductibles and any coinsurance condition, and check lost-income protection separately. 10,11,12
Key Differences in Commercial Property Insurance
A broad named client base and targeted portfolio sectors
AIG names hospitals, universities, and global manufacturers among organizations for which it has commercial-property options. Berkshire Hathaway Specialty Insurance identifies public entities, finance, healthcare, education, manufacturing, and retail as sectors for its property portfolios. These lists help screen for fit but do not establish underwriting acceptance. A buyer should compare its occupancy, geography, and portfolio size with the appetite in each actual proposal. 3 8
All-risk or selected single-peril placements
AIG does not publish a buyer-specific property capacity in its overview, while Berkshire Hathaway Specialty Insurance’s appetite guide lists a $100 million working layer and higher capacity for selected risks, with a $100,000 minimum premium for BHSI’s share. Those are program-level guide figures, not a quote. A portfolio buyer should ask which capacity and premium minimum apply to its locations. 3 9

AIG vs Berkshire Hathaway Specialty Insurance: Commercial Property Insurance: documented features by provider
| Criteria | AIG Commercial Property and Retail Property | Commercial property all-risk and selected single-peril/catastrophe offerings |
|---|---|---|
| Role in This Line | 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. | Confirm in your quote. |
| Who It’s For | 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. | BHSI targets property portfolios in sectors including public entities, finance, healthcare, education, manufacturing and retail. 8Company-reported. Commercial property risks described by BHSI. Material limitation: Target-sector language is not a complete appetite guide or individual acceptance commitment. |
| Coverage Features | 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. | BHSI lists all-risk commercial property and selected single-peril offerings such as earthquake, flood and windstorm. 8Company-reported. US commercial property risks. Material limitation: Single-peril availability is separate from all-risk and depends on peril, state, risk and capacity. |
| Limits and Retentions | The reviewed page does not state standard property limits, deductibles or retentions for a buyer. Confirm those amounts, covered causes and conditions in the quote and issued policy. 3Not publicly disclosed. AIG’s U.S. Commercial Property marketing page reviewed 2026-09-30; no buyer-specific quote or policy form was reviewed. | BHSI’s general property appetite guide lists a $100,000 minimum premium per policy for BHSI’s share and $100 million working-layer capacity, with more capacity for selected risks. 9Company-reported. U.S. general property appetite in guide dated 2026-02-10; per-policy premium applies to BHSI share. Material limitation: Working capacity is not an insured policy limit or quote. “More for select risks” is selective. Final terms, exclusions, issuer and availability require the policy/submission. |
| Risk Services | 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.
