Abstract: Disclosed herein is a system and method for terminating a pension plan through mutual annuitization. A mutual annuitization involves the formation of a new and dedicated mutual insurance company that issues group or individual annuity contracts to plan participants in a private pension plan. The plan sponsor would neither own any stock in the mutual insurance company, nor would it have voting or control rights or any right whatsoever to participate in the profits of the mutual insurance company. As a mutual insurance company, there are no shareholders as such. Instead mutuals have members, and it is the members who enjoy governance rights and participation rights in the company's profits, such as through policy dividend payments. In the mutual insurance company of the present invention, the pension plan participants are the mutual insurance company's sole members.
