Prior to September 11, 2001, when the World Trade Center in New York City was attacked by terrorists and destroyed, business insurers generally neither charged for nor excluded terrorism coverage because the chance of property damage from terrorist acts was considered minute. After 9/11, insurers reassessed that risk. For a year, terrorism coverage was scarce, as reinsurers were unwilling to reinsure policies in urban areas perceived to be vulnerable to attack.
In November, 2002, the Terrorism Risk Insurance Act (TRIA) was signed into law to ensure that American businesses would have access to affordable terrorism insurance.
The Act authorized the creation of a federal reinsurance plan, providing a system of shared public and private compensation for insured losses resulting from acts of terrorism. The federal government’s involvement helps offer some certainty for businesses, and enables the commercial insurance market to function, even though the threat of terrorism remains.
In January 2015, the Terrorism Risk Insurance Program Reauthorization Act (TRIPRA) was passed to extend TRIA through December 2020. It also made several changes to the reinsurance program, including reducing the federal share of insured terrorism losses incrementally through 2020, increasing the trigger threshold for federal involvement in insured terrorism losses incrementally through 2020, and increasing the mandatory recoupment of federal losses incrementally through 2020.
TRIA reduces uncertainty and allows insurance companies and businesses to be better prepared in the event of a terrorist attack.
