What Are the Key Differences Between AIG and Marsh McLennan Agency 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. [1] [5]

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. [1] [5]

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. [1] [5]
