Terrorism risk insurance program benefits taxpayers, policyholders, RAND study finds

October 10, 2007

Taxpayers save money and businesses are better protected with the Terrorism Risk Insurance Act (TRIA) in place than if the act is allowed to expire, according to a RAND Corporation study issued today.

The analysis found that TRIA, authorized by Congress following the attacks of Sept. 11, 2001, allows the insurance industry to play a larger role in compensating losses caused by smaller -- and presumed more likely -- terrorist attacks by transferring some of the risk for the largest attack to the government.

The study, which is the first to consider the effect of TRIA on government assistance for uninsured loses after an attack, shows that taxpayers are better served if TRIA remains in effect rather than being allowed to expire by Congress.

The study also says that taxpayers and policyholders could also benefit if the law were expanded to better address nuclear, chemical, biological and radiological (NCBR) attacks.

The study was conducted by the RAND Center for Terrorism Risk Management Policy. RAND is a nonprofit research organization.

Legislation is currently being considered by Congress that would extend and modify TRIA. The proposed legislation would require insurers to offer coverage for NCBR attacks and includes several additional provisions that transfer some of the risk for attacks on the scale of 9/11 or larger to the government.

The RAND study compares the performance of the current TRIA program and several alternative government interventions in the market for terrorism insurance over a wide range of scenarios.

Among the key findings: "Overall, TRIA improves the functioning of private insurance markets and ultimately saves the taxpayers money because it transfers risk for the largest terrorist attacks to the government," said Lloyd Dixon, a RAND economist and study co-author. "In return, the insurance industry is able to play a larger role in compensating losses caused by smaller, and more likely, attacks."

Dixon said a gap remains in the nation's ability to manage terrorism risk because the coverage for nuclear, biological, chemical, and radiological attacks is rarely available even with the current TRIA program. Thus, the RAND study examined possible changes to TRIA that would require insurers to offer policies that cover losses due to both conventional and NBCR attacks.

The study, "The Federal Role in Terrorism Insurance," finds that increasing assurances that insurers will not be liable for insured losses over the current $100 billion TRIA cap and lowering the amount that insurers would have to pay before government support would be available (the so-called "deductible") could improve outcomes for a program requiring insurers to offer policies that cover both conventional and NCBR attacks.

"Hardening the cap and reducing the deductible are both important to getting the best result from a TRIA program that includes NCBR coverage," said study co-author Robert Lempert. "It's a robust strategy that effectively addresses the existing insurer uncertainty over how exposed they are to losses over the cap."
