AIG Specialty is the surplus lines division of American International Group (AIG), providing specialized coverage for non-standard, high-hazard, or complex risks that are not typically served by the admitted insurance market. The brand operates primarily through a network of wholesale brokers to offer tailored products including environmental, healthcare liability, and excess casualty solutions. It is a cornerstone of AIG's commercial property-casualty portfolio, leveraging the global scale of its parent company to provide high-capacity limits for large-scale industrial and corporate exposures.
