Idaho Code § 41-302

A “mutual” insurer is an incorporated insurer without capital stock and the governing body of which is elected by its policy holders. This definition shall not be deemed to exclude as “mutual” insurers certain foreign insurers found by the director to be organized on the mutual plan under the laws of their states of domicile, but having temporary share capital or providing for election of the insurer’s governing body on a reasonable basis by policy holders and others.
