Excess of Loss Reinsurance (non-proportional)

An agreement to share specified losses. The reinsurer indemnifies the primary insurer for the amount of loss in excess of a specified retention. The retention amount can be stated as either a dollar amount or a percentage amount. The reinsurer does not participate in losses until a loss exceeds the amount retained by the primary insurers.
