3. Definition of Reinsurance “ Reinsurance is a contract of insurance whereby one insurer (called the reinsurer or assuming company) agrees, for a portion of the premium, to indemnify another insurer (called the reinsured or ceding company) for losses paid by the reinsured under insurance policies issued by the reinsured to its policyholders.”

5. Elements of Reinsurance  Reinsurance is a form of insurance.  There are only two parties to the reinsurance contract - the Reinsurer and the Reinsured - both of whom are insurers, i.e. entities empowered to insure.  The subject matter of a reinsurance contract is the insurance liability of the Reinsured undertaken by it under insurance policies issued to its own policyholders.  A reinsurance contract is an indemnity contract.

6. What Reinsurance Does 1. It converts the risk of loss of an insurer incurred by the reinsured under its policies according to its own needs. 2.It redistributes the premiums received by the reinsured, which now belong to the reinsured, according to its own business needs.

7. What Reinsurance Does Not Do Reinsurance does not:  Convert an uninsurable risk into an insurable risk.  Make loss either more or less likely to happen.  Make loss either greater or lesser in magnitude.  Convert bad business into good business. It is not Alchemy.  Reinsurance is not coinsurance.  Reinsurance is not banking – it is not the lending of money but it can have the same effect.  Reinsurance is not a security.

10. Stabilization Marketing Consideration Policyholders and stockholders like to be identified with a stable and well managed company. Management Consideration Planning for long term growth and development requires a more stable environment than an insurance company’s book of business is apt to provide.

11. Capacity  Refers to an insurer’s ability to provide a high limit of insurance for a single risk, often a requirement in today’s market.  Reinsurance can help limit an insurer’s loss from one risk to a level with which management and shareholders are comfortable.  Most states require that the maximum “net retention” from one risk must be less than 10% of policyholders’ surplus.

12. Catastrophe Protection  Objective is to limit adverse effects on P&L and surplus from a catastrophic event to a predetermined amount.  Covers multiple smaller losses from numerous policies issued by one primary insurer arising from one event.
