Mutual Insurance Companies are the companies with no capital stock, and owned by policyholders. The earnings of the company, over and above the payments of the losses, operating expenses and reserves, are the properties of the policyholders. There are two types of mutual insurance companies. A nonassessable mutual charges a fixed premium and the policyholders cannot be assessed further. Legal reserves and surplus are maintained to provide payment of all claims. Assessable mutuals are companies that charge an initial fixed premium and, if that isn't sufficient, might assess policyholders to meet losses in excess of the premiums that have been charged.
