Quota Share Reinsurance
An agreement whereby the ceding company is bound to cede and the reinsurer is bound to accept a fixed proportion of every risk written by the ceding company within a defined category of business. The reinsurer thus shares proportionally in all losses and receives the same proportion of all premiums. Commission is usually negotiated.
An arrangement whereby reinsurances are placed one against another so that a ceding company will only place a share of its business with a reinsurer who is willing to provide a similar share of its own business. Reciprocity is normally confined to fire proportional business and is occasionally based on an equivalent profit exchange rather than on premium income.
