12 C.F.R. § 1026.16
(b) Advertisement of terms that require additional disclosures.
(1) Any term required to be disclosed under § 1026.6(b)(3) set forth affirmatively or negatively in an advertisement for an open-end (not home-secured) credit plan triggers additional disclosures under this section. Any term required to be disclosed under § 1026.6(a)(1) or (a)(2) set forth affirmatively or negatively in an advertisement for a home-equity plan subject to the requirements of § 1026.40 triggers additional disclosures under this section. If any of the terms that trigger additional disclosures under this paragraph is set forth in an advertisement, the advertisement shall also clearly and conspicuously set forth the following:
(c) Catalogs or other multiple-page advertisements; electronic advertisements.
(1) If a catalog or other multiple-page advertisement, or an electronic advertisement (such as an advertisement appearing on an Internet Web site), gives information in a table or schedule in sufficient detail to permit determination of the disclosures required by paragraph (b) of this section, it shall be considered a single advertisement if:
(d) Additional requirements for home-equity plans—(1) Advertisement of terms that require additional disclosures. If any of the terms required to be disclosed under § 1026.6(a)(1) or (a)(2) or the payment terms of the plan are set forth, affirmatively or negatively, in an advertisement for a home-equity plan subject to the requirements of § 1026.40, the advertisement also shall clearly and conspicuously set forth the following:
(2) Discounted and premium rates. If an advertisement states an initial annual percentage rate that is not based on the index and margin used to make later rate adjustments in a variable-rate plan, the advertisement also shall state with equal prominence and in close proximity to the initial rate:
(3) Balloon payment. If an advertisement contains a statement of any minimum periodic payment and a balloon payment may result if only the minimum periodic payments are made, even if such a payment is uncertain or unlikely, the advertisement also shall state with equal prominence and in close proximity to the minimum periodic payment statement that a balloon payment may result, if applicable. A balloon payment results if paying the minimum periodic payments does not fully amortize the outstanding balance by a specified date or time, and the consumer is required to repay the entire outstanding balance at such time. If a balloon payment will occur when the consumer makes only the minimum payments required under the plan, an advertisement for such a program which contains any statement of any minimum periodic payment shall also state with equal prominence and in close proximity to the minimum periodic payment statement:
(4) Tax implications. An advertisement that states that any interest expense incurred under the home-equity plan is or may be tax deductible may not be misleading in this regard. If an advertisement distributed in paper form or through the Internet (rather than by radio or television) is for a home-equity plan secured by the consumer's principal dwelling, and the advertisement states that the advertised extension of credit may exceed the fair market value of the dwelling, the advertisement shall clearly and conspicuously state that:
(6) Promotional rates and payments.
(i) Definitions. The following definitions apply for purposes of paragraph (d)(6) of this section:
(B) Promotional payment. The term “promotional payment” means:
(1) For a variable-rate plan, any minimum payment applicable for a promotional period that:
(i) Is not derived by applying the index and margin to the outstanding balance when such index and margin will be used to determine other minimum payments under the plan; and
(ii) Is less than other minimum payments under the plan derived by applying a reasonably current index and margin that will be used to determine the amount of such payments, given an assumed balance.
(2) For a plan other than a variable-rate plan, any minimum payment applicable for a promotional period if that payment is less than other payments required under the plan given an assumed balance.
(ii) Stating the promotional period and post-promotional rate or payments. If any annual percentage rate that may be applied to a plan is a promotional rate, or if any payment applicable to a plan is a promotional payment, the following must be disclosed in any advertisement, other than television or radio advertisements, in a clear and conspicuous manner with equal prominence and in close proximity to each listing of the promotional rate or payment:
(2) Definitions.
(4) Stating the promotional period and post-promotional rate or fee. If any annual percentage rate that may be applied to the account is a promotional rate under paragraph (g)(2)(i) of this section or any fee that may be applied to the account is a promotional fee under paragraph (g)(2)(iv) of this section, the information in paragraphs (g)(4)(i) and, as applicable, (g)(4)(ii) or (iii) of this section must be stated in a clear and conspicuous manner in the advertisement. If the rate or fee is stated in a written or electronic advertisement, the information in paragraphs (g)(4)(i) and, as applicable, (g)(4)(ii) or (iii) of this section must also be stated in a prominent location closely proximate to the first listing of the promotional rate or promotional fee.
(4) Stating the terms of the deferred interest or similar offer. If any deferred interest offer is advertised, the information in paragraphs (h)(4)(i) and (h)(4)(ii) of this section must be stated in the advertisement, in language similar to Sample G-24 in appendix G to this part. If the deferred interest offer is included in a written or electronic advertisement, the information in paragraphs (h)(4)(i) and (h)(4)(ii) of this section must also be stated in a prominent location closely proximate to the first statement of “no interest,” “no payments,” “deferred interest,” “same as cash,” or similar term regarding interest or payments during the deferred interest period.
