	Introduction

Prior to the September 11, 2001 terrorist attacks, insurance covering terrorism losses wasnormally included in general insurance policies without a specific premium being paid. In response to the new appreciation of the threat and the perceived inability to calculate theprobability and loss data critical for pricing insurance, both primary insurers and reinsurers pulledback from offering terrorism coverage. Many argued that terrorism risk is essentially uninsurableby the private market due to the uncertainty and potentially massive losses involved. Becauseinsurance is required for a variety of economic transactions, many feared that a lack of insuranceagainst terrorism loss would have wider economic impact, particularly on large-scale developmentsin urban areas that would be tempting targets for terrorism. Congress responded to the disruption in the insurance market by passing the Terrorism RiskInsurance Act of 2002 (1) (TRIA), which was signed by the President in November 2002. TRIA created the Terrorism RiskInsurance Program, which was enacted as a temporary program, expiring at the end of 2005, to calmthe insurance markets through a government backstop for terrorism losses and give the privateindustry time to gather the data and create the structures and capacity necessary for private insuranceto cover terrorism risk. Terrorism insurance has become widely available under TRIA and the insurance industry hasgreatly expanded its financial capacity in the past three years. Legislative Action

Congress responded to the impending expiration of TRIA with two different bills thatinitially passed the respective houses. The Senate bill, Senator Christopher Dodd's S. 467 , was approved by the Senate on November, 18, 2005. The large majority of the language fromthe House bill, Representative Richard Baker's H.R. 4314 , was inserted into S.467 and passed by the House on December 7, 2005. S. 467 was entitled theTerrorism Risk Insurance Extension Act, whereas H.R. 4314 was entitled the TerrorismRisk Insurance Revision Act and the titles did reflect essential differences between the two bills. As amended, S. 467 would have extended the current program two years andfurther increased the private sector's exposure to terrorism risk over the life of the act, as did theoriginal legislation. During the three years covered by the initial act, insurance industry deductiblesand aggregate retention rose each year. S. 467 continued to increase these. It would havealso reduced the types of insurance covered by the program and increased the size of a terrorist eventnecessary to trigger the program. 4314)

H.R. In the case of a terrorist act, the deductibles and event triggers would havereset to lower levels, with deductibles possibly as low as 5% in the event of a large attack.
Prior to the September 11, 2001, terrorist attacks, insurance covering terrorism losses wasnormally included in general insurance policies without cost to policyholders. Following the attacks,both primary insurers and reinsurers pulled back from offering terrorism coverage, citing particularlyan inability to calculate the probability and loss data critical for insurance pricing. Some argued thatterrorism risk would never be insurable by the private market due to the uncertainty and potentiallymassive losses involved. Because insurance is required for a variety of economic transactions, it wasfeared that a lack of insurance against terrorism loss would have wider economic impact.
Congress responded to the disruption in the insurance market by passing the Terrorism RiskInsurance Act of 2002 (TRIA). TRIA created a temporary program, expiring at the end of 2005, tocalm the insurance markets through a government backstop for terrorism losses and to give theprivate industry time to gather the data and create the structures and capacity necessary for privateinsurance to cover terrorism risk. From 2002 to 2005, terrorism insurance became widely availableand largely affordable, and the insurance industry greatly expanded its financial capacity. There was,however, little apparent success on a longer term private solution and fears persisted about widereconomic consequences if insurance were not available. To a large degree, the same concerns andarguments that accompanied the initial passage of TRIA were before Congress as it considered TRIAextension legislation.
Congress responded to the impending expiration of TRIA with the passage of two differentbills. The Senate bill, S. 467 , was approved by the Senate on November 18, 2005. Thelarge majority of the language from the House bill, H.R. 4314 , was inserted into S.467 and passed by the House on December 7, 2005. S. 467 was titled theTerrorism Risk Insurance Extension Act, whereas H.R. 4314 was titled the Terrorism RiskInsurance Revision Act. These titles did reflect essential differences between the two bills. S.467 extended the current program by two years and further increased the private sector'sexposure to terrorism risk, as did the original act. (During the three years covered by the initial act,insurance industry deductibles and aggregate retention rose each year.) S. 467 continuedto increase these and also reduced the types of insurance covered by the program and increased thesize of terrorist event necessary to trigger the program. H.R. 4314 extended the programfor two or possibly three years and substantially revised many aspects of it. Among the notablechanges, it excluded some lines of coverage and included others that were not covered before. Itsegmented lines of insurance, introducing different deductibles for different lines. It included theconcept of resetting the deductibles and the trigger amount to lower amounts if a terrorist attackoccurs in the future. The final version signed into law closely tracked the Senate legislation.
This report briefly outlines the issues involved with terrorism insurance and includes aside-by-side of the initial TRIA, TRIA-extension legislation as considered in the House and Senate,and the final bill as signed by the President. It will not be updated.
