This book looks at the issues involved with terrorism insurance and includes a side-by-side comparison of the previous law, the two House TRIA-extension bills, and the Senate bill that was ultimately signed by the President. Prior to the September 11, 2001 terrorist attacks, insurance covering terrorism losses was normally included in general insurance policies without additional cost to the policyholders. Following the attacks, both primary insurers and reinsurers pulled back from offering terrorism coverage. Congress responded to the disruption in the insurance market by passing the Terrorism Risk Insurance Act (TRIA) of 2002. TRIA created a temporary program to calm the insurance markets through a government backstop for terrorism losses. In addition to the continuing debate about TRIA, this book also discusses commonly accepted principles of insurability and whether nuclear, biological, chemical, or radiological (NBCR) risks are measurable and predictable and whether private insurers currently are exposed to NBCR risks and the challenges they face in pricing such risks.
