AIG lists General Liability within selected named programs; Marsh McLennan Agency describes adviser-led placement based on a business’s exposures. ## Research Scope and Use Use this comparison to evaluate AIG and Marsh McLennan Agency for General Liability Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote. ## Summary AIG’s directory identifies selected program audiences, while Marsh McLennan Agency says advisers assess operations, assets, liabilities and loss exposure when arranging General Liability. [3](https://www.aig.com/home/risk-solutions/business/aig-programs "AIG Programs Insurance") [6](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA") ## 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](https://www.aig.com/investor-relations "Investor Relations") [2](https://www.aig.com/home/risk-solutions/business "Business") [AIG profile](https://spot.insure/insurance-providers/aig) ## What Is Marsh McLennan Agency? Marsh McLennan Agency provides business insurance and employee health and benefits, alongside retirement, wealth, and private-client services across the United States and Canada. Its US small-business page lists six common coverage types and directs buyers to request a personalized quote by phone; the insurer and terms for a specific placement must be confirmed in the proposal. [4](https://www.marshmma.com/us/mma/about-us.html "Who We Are") [5](https://www.marshmma.com/us/solutions/small-business.html "Small Business Insurance Solutions") [Marsh McLennan Agency profile](https://spot.insure/insurance-providers/marsh-mclennan-agency) ## What Is General Liability Insurance? General liability can protect your business when a customer or visitor claims you caused injury or damaged their property. It suits businesses serving customers or working on their premises; your own building, tools and stock need property coverage. [7](https://www.iii.org/article/commercial-general-liability-insurance "Commercial general liability insurance") [8](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [9](https://www.hiscox.com/documents/partner-agent/specimen_forms/GL_Form.pdf "Commercial General Liability Coverage Form") ## Key Differences in General Liability Insurance ### Named program fit or exposure review AIG’s directory ties General Liability to named programs for specific audiences such as crane and rigging, dental, leisure and towing businesses. Marsh McLennan Agency describes advisers evaluating a business’s operations, assets, liabilities and loss exposure to discuss GL. A buyer can use this difference to choose the first conversation: match your class to an AIG program, or bring your exposure details to an MMA adviser. Neither public description confirms an offer for your account. [3](https://www.aig.com/home/risk-solutions/business/aig-programs "AIG Programs Insurance") [6](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA") ### What the public descriptions establish Their published roles call for different quote questions. AIG describes program-level underwriting and claims resources for program administrators; Marsh McLennan Agency describes arranging coverage through an adviser or specialist. Ask AIG which administrator and issuing insurer apply to the named program; ask MMA which market would issue the proposed policy and who will service it. [3](https://www.aig.com/home/risk-solutions/business/aig-programs "AIG Programs Insurance") [6](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA") ### Requesting the specific policy form AIG’s overview names particular programs but leaves limits and policy terms to the applicable form. MMA’s page likewise describes an advisory review, not policy wording. For either quote, compare the same operations, limits, exclusions and endorsements, and confirm whether completed-operations protection is included or separately addressed. [3](https://www.aig.com/home/risk-solutions/business/aig-programs "AIG Programs Insurance") [6](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA") ## What to Confirm in General Liability Insurance Quotes - Which AIG program covers your class, and what limits and forms does its administrator propose? - Which insurer and policy wording would MMA recommend after reviewing your operations and loss exposures? ## Offering Details | Criteria | AIG General Liability Within Named Programs | Marsh McLennan Agency general liability (official overview) | | --- | --- | --- | | Role in This Line | This evidence supports general liability only within the named AIG programs cited here; it does not establish one uniform standalone general liability product across all businesses.
