Louisiana Revised Statutes Tit. 22, § 1268. Interest on refund; exception

(1) The delivery to the insured of the written notice of such cancellation, elimination, or reduction.

(2) Delivery to the insurer's state, regional, or home office, from which such refund would issue, of the written request for such cancellation, elimination, or reduction. An insurer shall be deemed in compliance with this Section and not subject to the further accruement of interest by furnishing timely evidence of the mailing of such refund to the last known address of the insured. However, when the insured continues to maintain a policy of insurance with the insurer, or an affiliated insurer, and the amount of the refund plus interest is twenty-five dollars or less, the insurer may credit the amount of the payment against future premiums. The insurer shall give written notice to the insured of the credit and the amount at policy renewal.
