For the purpose of calculating any refund of interest required under subsection (a) for any precomputed consumer credit transaction of a term exceeding 61 months which is consummated after September 30, 1993, the creditor shall compute the refund based on a method which is at least as favorable to the consumer as the actuarial method.
If the customer’s request is in writing, the statement under paragraph (1) shall be in writing.
A consumer shall be entitled to obtain 1 statement under paragraph (1) each year without charge.
Any creditor may impose a reasonable fee to cover the cost of providing any statement under paragraph (1) to any consumer in addition to the 1 free annual statement required under paragraph (3) if the amount of the charge for such additional statement is disclosed to the consumer before furnishing such statement.
The term “actuarial method” means the method of allocating payments made on a debt between the amount financed and the finance charge pursuant to which a payment is applied first to the accumulated finance charge and any remainder is subtracted from, or any deficiency is added to, the unpaid balance of the amount financed.
