Reinsurance(redirected from reinsures)
Also found in: Dictionary, Thesaurus, Medical, Legal.
An insurance policy for insurers. In reinsurance, one insurer cedes a portion of its portfolio of policyholders to another insurer in exchange for paying a fee. There exists the possibility that too many policyholders will make a claim and a single insurer will be unable to pay the benefit without ruining itself. This is especially true for disaster insurance and other similar policies. Reinsurance reduces this risk. It is also called stop-loss insurance.
