Differences in the lengths of months are disregarded and, for any period less than a month, each day may be counted as one thirtieth (1/30) of a month.(f) Notwithstanding any premium finance agreement, any insured may prepay the obligation in full at any time. In this event, the insured shall receive a refund credit, which refund credit shall represent at least as great a proportion of the interest as the sum of the periodic balances after the month in which prepayment is made bears to the sum of all periodic balances under the schedules of installments in the agreement. Where the amount of the refund credit is less than one dollar ($1.00), no refund need be made.Acts 1980, ch. 920, § 8; 1981, ch. 414, § 1; 1983, ch. 431, § 1.
