Surplus reinsurance

form of proportional reinsurance under which the risk is not spread between the insurer and reinsurer on the basis of a previously agreed, set quota share. Instead, the insurer determines a maximum sum insured per risk up to which it is prepared to be liable. Risks that exceed the ceding company’s retention (surpluses) are borne by the reinsurer. The reinsurer’s lines thus vary according to the level of the retention and the sum insured of the reinsured contract. The reinsurer’s liability is generally limited to a multiple of the ceding company’s retention.
