what is excess of loss reinsurance 
excess of loss reinsurance is a type of reinsurance in which the reinsurer indemnifies or compensates the ceding company for losses that exceed a specified limit a reinsurer is a company that provides financial protection to insurance companies a ceding company is an insurance company that transfers the insurance portfolio to a reinsurer excess of loss reinsurance is a form of non proportional reinsurance non proportional reinsurance is based on loss retention with non proportional reinsurance the ceding company agrees to accept all losses up to a predetermined level depending on the language of the contract excess of loss reinsurance can apply to either all loss events during the policy period or losses in aggregate treaties may also use bands of losses that are reduced with each claim reinsurers and ceding companies will use cost calculations such as the burning cost ratio to determine prices understanding excess of loss reinsurancetreaty or facultative reinsurance contracts often specify a limit in losses for which the reinsurer will be responsible this limit is agreed to in the reinsurance contract it protects the reinsurance company from dealing with unlimited liability in this way treaty and facultative reinsurance contracts are similar to a standard insurance contract which provides coverage up to a specific amount while this is beneficial to the reinsurer it places the onus on the insurance company to reduce losses excess of loss reinsurance takes a different approach than treaty or facultative reinsurance the reinsurance company is held responsible for the total amount of losses above a certain limit for example a reinsurance contract with an excess of loss provision may indicate that the reinsurer is responsible for losses over 500 000 in this case if aggregate losses amount to 600 000 then the reinsurer will be responsible for 100 000 excess of loss reinsurance can also work in a slightly different way rather than require the reinsurer to be responsible for all losses over a certain amount the contract may instead indicate that the reinsurer is responsible for a percentage of losses over that threshold this means that the ceding company and the reinsurer will share aggregate losses for example a reinsurance contract with an excess of loss provision may indicate that the reinsurer is responsible for 50 of the losses over 500 000 in this case if aggregate losses amount to 600 000 the reinsurer will be responsible for 50 000 and the ceding company will be responsible for 50 000 by covering itself against excessive losses an excess of loss reinsurance policy gives the ceding insurer more security for its equity and solvency it can also provide more stability when unusual or major events occur reinsurance also allows an insurer to underwrite policies that cover a larger volume of risks without excessively raising the costs of covering their solvency margins the amount by which the assets of the insurance company at fair values are considered to exceed its liabilities and other comparable commitments in fact reinsurance makes substantial liquid assets available for insurers in case of exceptional losses
