9. 41-9 Insurance Aspects of Terrorism With uncertainty people buy insurance to minimize the financial consequences of a foreseeable, but not necessarily predictable, problem. (auto insurance, home owners insurance etc.) With 9/11 there was uncertainty about how bad it could get Insurance companies were uncertain whether they could survive financially

10. 41-10 Reinsurance Reinsurance: like insurance except it is bought by insurance companies from other larger insurance companies (or from consortiums of insurance companies). Reinsurance allows for large losses to be shared among insurance companies. Reinsurance works well when the uncertainty to the insurance company is large but is manageable to a reinsurance company. Reinsurance markets failed post-9/11 and the federal government stepped in to be the reinsurer of last resort.
