(i) Prior to the commencement of that period, the card issuer disclosed in writing to the consumer, in a clear and conspicuous manner, the length of the period and the annual percentage rate, fee, or charge that would apply after expiration of the period; and

(ii) Upon expiration of the specified period:

(i) The annual percentage rate varies according to an index that is not under the card issuer's control and is available to the general public; and

(ii) The increase in the annual percentage rate is due to an increase in the index.

(i) If a card issuer discloses an increased annual percentage rate, fee, or charge pursuant to § 1026.9(b), the card issuer must not apply that rate, fee, or charge to transactions that occurred prior to provision of the notice;

(ii) If a card issuer discloses an increased annual percentage rate, fee, or charge pursuant to § 1026.9(c) or (g), the card issuer must not apply that rate, fee, or charge to transactions that occurred prior to or within 14 days after provision of the notice; and

(iii) This exception does not permit a card issuer to increase an annual percentage rate or a fee or charge required to be disclosed under § 1026.6(b)(2)(ii), (iii), or (xii) during the first year after the account is opened, while the account is closed, or while the card issuer does not permit the consumer to use the account for new transactions. For purposes of this paragraph, an account is considered open no earlier than the date on which the account may first be used by the consumer to engage in transactions.

(i) The card issuer must disclose in a clear and conspicuous manner in the notice of the increase pursuant to § 1026.9(c) or (g):

(ii) If the card issuer receives six consecutive required minimum periodic payments on or before the payment due date beginning with the first payment due following the effective date of the increase, the card issuer must reduce any annual percentage rate, fee, or charge increased pursuant to this exception to the annual percentage rate, fee, or charge that applied prior to the increase with respect to transactions that occurred prior to or within 14 days after provision of the § 1026.9(c) or (g) notice.

(i) Prior to commencement of the arrangement (except as provided in § 1026.9(c)(2)(v)(D)), the card issuer has provided the consumer with a clear and conspicuous written disclosure of the terms of the arrangement (including any increases due to the completion or failure of the arrangement); and

(ii) Upon the completion or failure of the arrangement, the card issuer must not apply to any transactions that occurred prior to commencement of the arrangement an annual percentage rate, fee, or charge that exceeds the annual percentage rate, fee, or charge that applied to those transactions prior to commencement of the arrangement.

(i) The card issuer changes the index and margin used to determine the annual percentage rate if the original index becomes unavailable, as long as historical fluctuations in the original and replacement indices were substantially similar, and as long as the replacement index and replacement margin will produce a rate substantially similar to the rate that was in effect at the time the original index became unavailable. If the replacement index is newly established and therefore does not have any rate history, it may be used if it and the replacement margin will produce a rate substantially similar to the rate in effect when the original index became unavailable; or

(ii) If a variable rate on the plan is calculated using a LIBOR index, the card issuer changes the LIBOR index and the margin for calculating the variable rate on or after April 1, 2022, to a replacement index and a replacement margin, as long as historical fluctuations in the LIBOR index and replacement index were substantially similar, and as long as the replacement index value in effect on October 18, 2021, and replacement margin will produce an annual percentage rate substantially similar to the rate calculated using the LIBOR index value in effect on October 18, 2021, and the margin that applied to the variable rate immediately prior to the replacement of the LIBOR index used under the plan. If the replacement index is newly established and therefore does not have any rate history, it may be used if the replacement index value in effect on October 18, 2021, and the replacement margin will produce an annual percentage rate substantially similar to the rate calculated using the LIBOR index value in effect on October 18, 2021, and the margin that applied to the variable rate immediately prior to the replacement of the LIBOR index used under the plan. If the replacement index is not published on October 18, 2021, the card issuer generally must use the next calendar day for which both the LIBOR index and the replacement index are published as the date for selecting indices values in determining whether the annual percentage rate based on the replacement index is substantially similar to the rate based on the LIBOR index. The one exception is that if the replacement index is the spread-adjusted index based on SOFR recommended by the Alternative Reference Rates Committee for consumer products to replace the 1-month, 3-month, 6-month, or 1-year U.S. Dollar LIBOR index, the card issuer must use the index value on June 30, 2023, for the LIBOR index and, for the SOFR-based spread-adjusted index for consumer products, must use the index value on the first date that index is published, in determining whether the annual percentage rate based on the replacement index is substantially similar to the rate based on the LIBOR index.

(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.
