Premiums and refunds.

A. Any insurer may revise its schedules of premium rates from time to time and shall file such revised schedules with the superintendent. No insurer shall issue any credit life insurance policy or credit health insurance policy for which the premium rate exceeds that determined by the schedules of such insurer as then on file with the superintendent. B. Each individual policy or group certificate shall provide that in the event of termination of the insurance prior to the scheduled maturity date of the indebtedness, any refund of an amount paid by the debtor for insurance shall be paid or credited promptly to the person entitled thereto; provided, however, that the superintendent shall prescribe a minimum refund and no refund which would be less than such minimum need be made. The formula to be used in computing such refund shall be filed with and approved by the superintendent. C. If a creditor requires a debtor to make any payment for credit life insurance or credit health insurance and an individual policy or group certificate of insurance is not issued, the creditor shall immediately give written notice to such debtor and shall promptly make an appropriate credit to the account. D. The amount charged to a debtor for any credit life or credit health insurance shall not exceed the premiums charged by the insurer, as computed at the time the charge to the debtor is determined. E. Nothing in this article shall be construed to authorize any payments for insurance now prohibited under any statute, or rule thereunder, governing credit transaction.
