Equal apportionment of an insured loss by two or more Insurers so that each Insurer contributes an equal amount toward the loss until each Insurer’s contributes an equal amount toward the loss until each Insurer’s contribution equals the least of their individual limits of liability. For example, if Insurer A has a Rs. 2,00,000 Policy for a particular loss and Insurer B has a Rs. 3,00,000 Policy for that same loss, each Insurer would pay half of any loss not exceeding Rs. 4,00,000. For a loss above Rs. 4,00,000, each Insurer would pay Rs. 2,00,000 and Insurer B would pay any remaining loss until it had paid its Rs. 3,00,000 limit.
