## 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.

[AIG profile](https://spot.insure/insurance-providers/aig)

## What Is Umbrella and Excess Liability Insurance?

Umbrella or excess insurance adds liability limits above the policies named in the quote after a covered claim exhausts their limits. It may fit if a contract sets higher limits; check which primary policies are listed and any gaps between them. [10](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance "Liability Insurance") [11](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [12](https://www.insurance.ca.gov/0200-industry/0050-renew-license/0200-requirements/casualty/lines-of-ins.cfm "Lines of Insurance") [13](https://www.coverdash.com/coverage "Coverage Hub") [14](https://kinro.com/products "Products")

## Key Differences in Umbrella and Excess Liability Insurance

### New placement versus review of existing coverage

AIG markets admitted and non-admitted capacity for lead umbrella, mid-excess, and high-excess positions. WithCoverage brokers and includes umbrella in an audit that benchmarks existing terms, limits, and premiums. If you need new capacity, ask AIG for a proposed layer; ask WithCoverage whether its audit would also move placement if it identifies a gap. [3](https://www.aig.com/home/risk-solutions/business/casualty/excess-casualty "Excess Casualty Insurance") [7](https://www.withcoverage.com/industries/construction "Construction Insurance & Risk Management")

### Audit inputs and account services

WithCoverage says its no-cost construction audit can proceed without leaving the current broker and typically takes about a business day after documents arrive. AIG describes in-house risk experts and claims specialists but does not describe the same document-review timeline. Ask WithCoverage which policies and schedules it needs, and AIG for the policy wording and structure to compare. [3](https://www.aig.com/home/risk-solutions/business/casualty/excess-casualty "Excess Casualty Insurance") [7](https://www.withcoverage.com/industries/construction "Construction Insurance & Risk Management")

## What to Confirm in Umbrella and Excess Liability Insurance Quotes

- Ask WithCoverage what documents its construction audit needs and whether it can place revised coverage; ask AIG for limits, attachments, underlying forms, and named insurer.

## AIG Reviews

Review Score: 4.4 / 10 from 2 rated sources, equally weighted.

Customer ratings for AIG are low: Trustpilot shows 1.9 out of 5 from 252 reviews, and NerdWallet gives 2.5 stars and notes more claims complaints than expected. These pages cover many AIG products and countries, so they only loosely describe business insurance.

- NerdWallet: NerdWallet editorial rating 2.5 (stars). NerdWallet’s editorial business-insurance comparison; the AIG entry concerns commercial liability and property insurance, not a quantified policyholder-review sample. The page’s complaint statement and 2.5-star editorial rating are source-specific and must not be recast as a consumer average. Checked 2026-09-29.

- Trustpilot: Trustpilot TrustScore 1.9 (out of 5); 252 reviews. Consumer reviews on aig.com’s Trustpilot profile span products and countries, including personal, travel, device/service and other experiences; they do not isolate U.S. commercial-P&C policyholders or a single issuing insurer.
