• Contribution is the principle that two or more insurers, each responsible for a covered loss, must share in the payment of that loss. Having paid its share of the loss, the insurer may be entitled to a fair premium - a legal right to recover part of the payment from another insurer whose policy was also applicable. Many insurance policies provide for a formula whereby premiums will be made between multiple insurers. Two standard methods are “Contribution by limits” and “Deposit in equal shares”.
