Oregon Revised Statutes Insurance § 743.378

(1) Each individual policy or group certificate of credit life or credit health insurance, or both, 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. However, the Director of the Department of Consumer and Business Services 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 director.

(2) 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.

(3) The amount charged to a debtor for credit life insurance and for credit health insurance shall not exceed the respective premiums charged by the insurer, as computed at the time the charge to the debtor is determined.
