(1) Medicare supplement policies shall return the following to policyholders in the form of aggregate benefits under the policy, with respect to the lifetime of the policy, on the basis of earned premiums and on the basis of incurred claims experience or, if coverage is provided by a health maintenance organization based on service rather than reimbursement, incurred health care expenses, and in accordance with accepted actuarial principles and practices:
(a) At least 75 percent of the aggregate amount of premiums earned in the case of group policies.
(b) For individual policies issued or renewed prior to July 1, 1989, at least 60 percent of the aggregate amount of premiums earned and for individual policies issued on or after July 1, 1989, at least 65 percent of the aggregate amount of premiums earned.

(2) Each entity providing Medicare supplement policies or certificates in this state shall file annually its rates, rating schedules, and supporting documentation demonstrating that it is in compliance with the applicable loss ratio standards of this code. The filing of rates and rating schedules shall demonstrate that the actual and expected losses in relation to premiums comply with the requirements of this section.
(3) For the purposes of this section, a policy form complies with the loss ratio standards if:
(a) For the most recent year, the ratio of the incurred losses to earned premiums for policies or certificates which have been in force for 3 years or more is greater than or equal to the applicable percentages contained in this section; and
(b) The expected losses in relation to premiums over the lifetime of the policy comply with the requirements of this section.
An expected third-year loss ratio that is greater than or equal to the applicable percentage must be demonstrated for policies or certificates in force less than 3 years.
