What Is a Commutation Agreement?

A commutation agreement is a reinsurance agreement in which the reinsurer and the ceding company agree on the conditions under which all obligations for both parties in the agreement are discharged.

A commutation agreement includes the methods for valuing any claims or outstanding charges, and how any remaining losses or premiums are to be paid.

Key Takeaways

  • A commutation agreement is an agreement between a reinsurer and a ceding company that details the stipulations in which contractual obligations are discharged.
  • These agreements include ways claims are valued, as well as how to pay remaining losses and premiums.
  • To vacate a reinsurance treaty, the ceding company and reinsurer negotiate and then develop a commutation agreement.
  • Generally, the agreement price begins with determining the cost to the reinsurer of not commuting.

Understanding Commutation Agreements

Insurance companies use reinsurance to reduce their overall risk exposure in exchange for a portion of the premium. Reinsurers are responsible for the risks that are ceded, with coverage limits determined in the reinsurance treaty. Reinsurance contracts can vary in length but may last for extended periods.

Sometimes an insurer—also called the ceding company—decides that it no longer needs to use a reinsurer. To exit the reinsurance treaty, it must negotiate with the reinsurer, with negotiations resulting in a commutation agreement.

An insurance company may consider exiting the reinsurance treaty for several reasons. Motives can include no longer wanting to underwrite a certain type of risk, recognizing that it’s more capable of handling the financial impact of claims than the reinsurer or, alternatively, determining that the reinsurer is not financially sound and thus poses a risk to its credit rating

Reinsurers, too, may conclude that the insurance company is likely to become insolvent and, subsequently, choose to exit the agreement to avoid involvement from government regulators.

Pricing a Commutation Agreement

There are a number of factors to consider when an insurer and reinsurer put a price to their commutation agreement. Usually, calculations begin with a determination of the cost to the reinsurer of not commuting. This cost is the difference between the following two quantities:

  • The present value of expected future paid losses—using an after-tax discount rate appropriate to the company and line of business.
  • The present value of the tax benefit related to the unwinding of the federal tax discounted reserves—using the Internal Revenue Service (IRS) prescribed discounting procedure.


Generally, the agreement price begins with determining the cost to the reinsurer of not commuting, which is the difference between the present value of both the expected future paid losses and the tax benefit associated with unwinding federal tax discounted reserves.

The cost of the commutation is calculated by subtracting from the cost of not commuting the value of the tax on the underwriting gain or loss generated by the commutation. This is the result of the takedown in reserves and payout of the final cost of commutation. 

This final cost of commutation represents the break-even price and reflects no loading for risk or profit.

Special Considerations

Commutation agreement negotiations can be complicated. Some types of insurance claims are filed long after the injury occurs as is the case with some types of liability insurance.

For example, problems with a building may only appear years after construction. Depending on the language of the reinsurance treaty, the reinsurer may still be responsible for claims made against the policy underwritten by the liability insurer. In other cases, claims may be made decades later.
