Reinsurance

Reinsurance is insurance for insurance companies. Just as individuals and businesses buy insurance to protect their assets, primary insurers, the companies that sell insurance to consumers, buy reinsurance to protect their profits and solvency. Reinsurance fosters competitive insurance markets by enabling smaller insurers to compete with larger ones. It strengthens U.S. insurers by giving them access to global resources. Reinsurance is often sold in layers, reaching up into the millions of dollars to protect insurance companies from possible, but statistically highly unlikely events, such as an extraordinary number of homeowners claims as a result of a hurricane or a large single event, such as the destruction of a high-value asset or a massive legal judgment. As shown in the chart below, many reinsurers of U.S. risks are owned by offshore firms.
