What Are the Key Differences Between AIG and Liberty Mutual 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. [1] [5]

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. [1] [5]
