CHARGES FOR DEFERRING INSTALLMENT.

(a) If a retail installment contract that provides for a time price differential that is computed using the add-on method or the scheduled installment earnings method is amended to defer all or a part of one or more installments for not longer than three months, the holder may collect from the retail buyer:

(1) a deferment charge in an amount computed on the amount deferred for the period of deferment at a rate that does not exceed the effective return for time price differential permitted for a monthly payment retail installment contract; and

(2) the amount of the additional cost to the holder for:

(A) premiums for continuing in force any insurance coverages provided for by the contract; and

(B) any additional necessary official fees.

(b) The minimum charge under Subsection (a)(1) is $1.

(c) If a retail installment contract that provides for a time price differential that is computed using the true daily earnings method is amended to defer all or a part of one or more installments, the holder may charge and receive from the retail buyer time price differential on the unpaid balance of the contract at the rate agreed to in the contract. At the time of deferment, the holder must provide the following written notice to the retail buyer that is boldfaced, capitalized, or underlined or otherwise conspicuously set out from any surrounding written material: "FINANCE CHARGES WILL CONTINUE TO ACCRUE ON THE UNPAID BALANCE AT THE CONTRACT RATE. BY DEFERRING ONE OR MORE INSTALLMENTS, YOU WILL PAY MORE FINANCE CHARGES THAN ORIGINALLY DISCLOSED." A holder does not collect a deferment charge by the accrual of time price differential on the unpaid balance of the contract.
