(c) Treatment of protected balances—

(1) Definition of protected balance.

(2) Repayment of protected balance. The card issuer must not require repayment of the protected balance using a method that is less beneficial to the consumer than one of the following methods:

(i) The method of repayment for the account before the effective date of the increase;

(ii) An amortization period of not less than five years, beginning no earlier than the effective date of the increase; or

(iii) A required minimum periodic payment that includes a percentage of the balance that is equal to no more than twice the percentage required before the effective date of the increase.

(d) Continuing application. This section continues to apply to a balance on a credit card account under an open-end (not home-secured) consumer credit plan after:

(1) The account is closed or acquired by another creditor; or

(2) The balance is transferred from a credit card account under an open-end (not home-secured) consumer credit plan issued by a creditor to another credit account issued by the same creditor or its affiliate or subsidiary (unless the account to which the balance is transferred is subject to §1026.40).
