What is the Alliance of American Insurers (AAI)?
The Alliance of American Insurers (AAI) was originally a coalition primarily composed of property-casualty insurance companies. Established as a political lobbying group, its mission was to advocate for the interests of this segment of the insurance industry by engaging with lawmakers and educating the public.
In 2004, the AAI merged with the National Association of Independent Insurers (NAII) to create the Property Casualty Insurers Association of America (PCI), which at that time represented over 40% of the U.S. property and casualty insurance market.
Later, in January 2019, PCI combined forces with the American Insurance Association (AIA) to form the American Property Casualty Insurance Association (APCIA). This new entity now represents nearly 60% of all property-casualty insurance carriers in the United States.
Understanding the Role and Influence of AAI
The PCI, as AAI’s successor, served as a powerful advocate for its members across all 50 states and on Capitol Hill, providing critical updates and insights relevant to their businesses. It maintained a presence with lobbyists in every state and regional managers in key capitals, monitoring legislation and regulations affecting property and casualty insurance at both state and federal levels.
