REINSURANCE
 Reinsurance is essentially insurance for insurance companies. It is a way for primary insurers to protect against unforeseen or extraordinary losses. Reinsurance also serves to limit liability on specific risks, to increase individual insurers’ capacity to write business, and to help insurers stabilize their business in the face of the wide swings in profit and loss margins that are inherent in the insurance business.
Reinsurance is an international business. According to the Reinsurance Association of America, 56.3 percent of the reinsurance purchased by U.S insurance companies was written by foreign reinsurance companies in 2007. If the domicile of the reinsurance company's parent is taken into account, foreign (or foreign-owned) reinsurance companies accounted for 83.4 percent of the market. This is because many U.S. reinsurance companies are owned by foreign firms.
