In 2017, more than 800 insurers wrote USD 215 billion in TRIPRA eligible premium, with a combined policyholder surplus of USD 683 billion. Considering the current 20 percent deductible requirement and policyholder surplus as a filter, Guy Carpenter's analysis concludes that small to midsize insurers are substantially more vulnerable to the annual increases in the TRIPRA industry trigger and their overall net retentions as a percentage of policyholder surplus.
Insurers with less than USD 300 million in surplus will likely need to incorporate additional private reinsurance market capacity to protect capital and satisfy rating agencies and regulators as the industry trigger increases to USD 200 million in 2020.
