## 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")

## What Are the Key Differences Between AIG and Gallagher Umbrella and Excess Liability Insurance?

### Form and underlying coverage

AIG markets lead umbrella, mid-excess, and high-excess positions and advertises up to $75 million on an individual account subject to underwriting. Gallagher places umbrella and excess within a broader casualty program and describes custom program design without publishing attachment points or limits. A buyer should obtain a layer-by-layer schedule from Gallagher and compare it with the capacity AIG can offer for the same underlying structure. [3](https://www.aig.com/home/risk-solutions/business/casualty/excess-casualty "Excess Casualty Insurance") [9](https://www.ajg.com/insurance/casualty-insurance/ "Casualty Insurance")

### Capacity and buyer support

Gallagher describes pre-renewal meetings, contract and form review, gap analysis, and a claims and loss-control advocacy group. AIG names its own risk and claims specialists and litigation-management strategies. Ask who reviews legacy losses, coordinates with underlying carriers, and advocates after a claim. [3](https://www.aig.com/home/risk-solutions/business/casualty/excess-casualty "Excess Casualty Insurance") [9](https://www.ajg.com/insurance/casualty-insurance/ "Casualty Insurance")

## What Should You Confirm in AIG and Gallagher Umbrella and Excess Liability Insurance Quotes?

- Ask AIG which position, attachment point, and legal insurer apply to the proposed tower. [3](https://www.aig.com/home/risk-solutions/business/casualty/excess-casualty "Excess Casualty Insurance")
- Ask Gallagher Umbrella/Excess to identify scheduled underlying policies, available limits, and form terms. [9](https://www.ajg.com/insurance/casualty-insurance/ "Casualty Insurance")

## AIG vs Gallagher Umbrella and Excess Liability Insurance Compared

| Criteria | AIG Excess Casualty and Lead Umbrella | Gallagher Umbrella/Excess Liability Insurance |
| --- | --- | --- |
| Role in This Line | AIG markets admitted and non-admitted excess casualty capacity, including lead umbrella, mid-excess and high-excess positions. The legal insurer and structure for a specific tower are account-specific. [3](https://www.aig.com/home/risk-solutions/business/casualty/excess-casualty "Excess Casualty Insurance") (Evidence: Company-reported; scope: Role in this product is limited to the description on the linked AIG source..) | Gallagher's Casualty practice places umbrella and excess liability coverage with outside carriers as one line within a broader casualty program; it does not underwrite the policy. [9](https://www.ajg.com/insurance/casualty-insurance/ "Casualty Insurance") (Evidence: Company-reported; scope: Group-level casualty practice page..) |
| Issuing Insurer | Confirm in your quote. | The casualty practice page does not name the insurer that would issue a given client's umbrella or excess policy. [9](https://www.ajg.com/insurance/casualty-insurance/ "Casualty Insurance") (Evidence: Not publicly disclosed; scope: Checked the group-level casualty practice page..) |
| Who It’s For | AIG describes lead umbrella, mid-excess and high-excess placements for a wide range of accounts, including small-business and corporate risks. It does not state an account-specific appetite or attachment eligibility. [3](https://www.aig.com/home/risk-solutions/business/casualty/excess-casualty "Excess Casualty Insurance") (Evidence: Company-reported; scope: Audience is the segment AIG names on the linked source; this is not an underwriting decision, quote or guarantee of availability..) | The casualty practice page does not name a target industry, size or minimum premium for umbrella/excess placements; it describes the practice generally as serving clients with a broader casualty program. [9](https://www.ajg.com/insurance/casualty-insurance/ "Casualty Insurance") (Evidence: Not publicly disclosed; scope: Checked the group-level casualty practice page on 2026-09-23..) |
| Coverage Features | AIG describes excess liability protection against severe liabilities and lead umbrella placements that may integrate with other casualty lines. The exact underlying policies, attachment points and follow-form terms depend on the placement. [3](https://www.aig.com/home/risk-solutions/business/casualty/excess-casualty "Excess Casualty Insurance") (Evidence: Company-reported; scope: AIG’s public product description is not the policy. Actual entitlement depends on the applicable issued form, endorsements and declarations..) | Gallagher groups umbrella/excess liability with automobile liability, workers' compensation and general/product liability under its casualty practice, offering "customized excess casualty program design and placement" and non-traditional alternative risk programs, but does not describe specific attachment points, exclusions or triggers. [9](https://www.ajg.com/insurance/casualty-insurance/ "Casualty Insurance") (Evidence: Company-reported; scope: Group-level casualty practice page; a service description, not a specific policy's insuring agreement..) |
| Limits and Retentions | AIG advertises up to $75 million total capacity on an individual-account basis, subject to underwriting. This is not a standard or guaranteed limit for a buyer. [3](https://www.aig.com/home/risk-solutions/business/casualty/excess-casualty "Excess Casualty Insurance") (Evidence: Not publicly disclosed; scope: This statement reports only what the linked public source discloses and does not substitute for a quote or issued policy..) | The casualty practice page does not publish specific umbrella/excess limits, attachment points or premium ranges; it says program structure, coverage, limits and pricing are designed to fit the client's current and future needs. [9](https://www.ajg.com/insurance/casualty-insurance/ "Casualty Insurance") (Evidence: Not publicly disclosed; scope: Checked the group-level casualty practice page..) |
| Risk Services | AIG describes in-house risk experts, claims specialists, litigation-management strategies and integration with domestic and foreign casualty platforms. Those services do not change policy wording. [3](https://www.aig.com/home/risk-solutions/business/casualty/excess-casualty "Excess Casualty Insurance") (Evidence: Company-reported; scope: The linked page describes company-reported support; specific account services and third-party arrangements must be confirmed..) | Gallagher describes pre-renewal meetings with a client's finance, HR, operations and risk-management stakeholders, a gap analysis and contract/form review to close coverage gaps between policies, and a dedicated claims and loss-control advocacy group that reviews legacy loss information to build claim-mitigation and loss-prevention programs. [9](https://www.ajg.com/insurance/casualty-insurance/ "Casualty Insurance") (Evidence: Company-reported; scope: Group-level casualty practice page; described at the practice level across all casualty lines, not exclusively for umbrella/excess..) |
