(a) If, in a premium finance agreement, a change in an insured’s policy that is caused by an amendment of the rate classification by endorsement or otherwise results in an increased principal balance and the amount under the previous contract has not been fully paid, the subsequent increase, at the insured’s option, may be consolidated with the previous contract if the agreement provides for consolidation.
(b) A consolidation under this section may be accomplished by a memorandum of agreement between the agent and the insured if, before the first scheduled payment date of the amended transaction, the insurance premium finance company provides to the insured the following information in writing:
(1) the amount of the premium increase;
(2) the down payment on the increase;
(3) the principal amount of the increase;
(4) the total amount of any finance charge on the increase;
(5) the total of the additional balance due;
(6) the outstanding balance due under the original agreement;
(7) the balance due under the consolidated agreement;
(8) the annual percentage rate of any finance charge on the additional balance due;
(9) the revised schedule of payments;
(10) the amount or method of computing the amount of any default, deferment, or similar charge authorized by Chapter 342, Finance Code, that is payable in the event of late payment; and
(11) the method of computing any unearned portion of the finance charge in the event of prepayment of the obligation.
