The reinsurer accepts liability wholly or partly on individual losses or losses on the whole account when they exceed an excess point (an attachment point) subject to an upper limit. Most non-proportional reinsurances are structured around excess of loss reinsurance. See EXCESS OF LOSS RATIO; EXCESS PER OCCURENCE; EXCESS PER RISK.
