Reinsurance: Arbitrage | Method of Reinsurance | Purpose of Reinsurance

Reinsurance is a means by which insurance company can protect itself with other insurance companies against the risk of losses, individuals and corporations obtain insurance policies to provide protection for various risks (hurricanes, earthquakes collisions, sickness and death etc.) reinsurers in turn provide insurance companies.

The insurance company may be motivated by arbitrage in purchasing reinsurance coverage at a lower rate that what they charge the insured for the underlying risk, which can be in the area of risk associated with any form of asset that is being issued or loaned against. It can be a car, a mortgage, an insurance (personal, fire, business etc.) and alike.

Reinsurers may operate under weaker regulation than their clients. This enables them to useless capital to cover any risk and to make less prudent assumptions when valuing the risk.

Method of Reinsurance

The method of reinsurance is determined one of five different ways.

  • Pro- Rata Basis: A reinsurer receives a percentage of the premium collected by the original insurance company for the business covered under the contract. The reinsurer pays the same percentage of losses incurred on this business.
  • Excess of loss Basic: The reinsurer agrees to accept all losses over a certain amount. This is the most common form of reinsurance.
  • Per Risk Excess of Loss: The reinsurer agrees to pay all losses over a certain amount on any one risk that is underwritten by the original company. This allows the original company to underwrite larger policies.
  • Catastrophic Excess of Loss: The reinsurer agrees to pay the total loss over a certain amount on all accumulated losses involved in a catastrophe. This protects the original company in the event of a catastrophic loss.
  • Aggregate Excess of Loss/stop loss: the reinsurance agrees to pay all losses over a certain amount for the original company’s losses for the period of the contract.
