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 Liberty Mutual Business Insurance?
Liberty Mutual spans small-commercial, commercial, specialty, surety, and reinsurance businesses. The insurer and distribution route depend on the product, so check the offer and policy before you compare terms. 4,5
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. 7,8,9
Key Differences in General Liability Insurance
Products and Advertising Claims
Liberty Mutual's GL page describes bodily injury, personal and advertising injury, property damage and product-injury exposures. AIG identifies general liability within selected programs but gives no universal form terms. A business selling products should ask both insurers how completed operations, advertising claims and exclusions are treated in the actual policy rather than rely on the category list. 3 6
Risk Services and Eligibility
Liberty Mutual describes risk-control support and a general-liability claims team, with applicant class and state availability dependent on the quote. AIG describes similar functions through its program administrators but only for named programs. Confirm class acceptance and which risk-control or claims contacts will serve the account before weighing those services. 3 6
