New Jersey Statutes Title 17. Corporations and Institutions for Finance and Insurance 17 § 3B-15

a. A lender may, if the agreement governing a revolving credit plan so provides, at any time amend the terms of the agreement with respect to the periodic percentage rates used to calculate interest, the method of computing the outstanding unpaid indebtedness to which those rates are applied, and the terms of the installment repayment schedule, subject to the limitations of subsection b. of this section.

b. The lender shall notify each affected borrower of any amendment pursuant to subsection a. by mailing or delivering to the borrower, at least 30 days before the effective date of the amendment, a clear and conspicuous written notice which shall describe the amendment and the existing terms of the agreement affected by the amendment and shall also set forth the effective date of the amendment and the pertinent information contemplated by the following provisions of this section. If the amendment has the effect of increasing the interest or other charges to be paid by the borrower by changing the method of calculating interest or the index used to calculate the interest, the amendment shall become effective only if the borrower uses the plan after a date specified in the notice which is at least 30 days after the giving of the notice, but which need not be the date the amendment becomes effective, by making a purchase or obtaining a loan, or if the borrower indicates to the lender in writing the borrower's express agreement to the amendment, and the amendment may become effective as to a particular borrower as of the first day of the billing period during which the borrower so used the borrower's account or so indicated agreement to the amendment. Any borrower who fails to use the borrower's account or so to indicate agreement to an amendment shall be permitted to pay the outstanding unpaid indebtedness in the borrower's account under the plan in accordance with the terms of the agreement governing the plan without giving effect to the amendment.

For purposes of this section a variation in periodic percentage rates of interest in accordance with the terms of the index established in the revolving credit plan agreement shall not be considered to be an amendment.
