(a) Authority. This subpart is issued by the Office of the Comptroller of the Currency under 12 U.S.C. 93a, 12 U.S.C. 1463, 1464 and 15 U.S.C. 1639h.

(b) Purpose. The OCC adopts this subpart pursuant to the requirements of section 129H of the Truth in Lending Act (15 U.S.C. 1639h) which provides that a creditor, including a national bank or operating subsidiary, a Federal branch or agency or a Federal savings association or operating subsidiary, may not extend credit in the form of a higher-risk mortgage without complying with the requirements of section 129H of the Truth in Lending Act (15 U.S.C. 1639h) and this subpart G. The definition of a higher-risk mortgage in section 129H is consistent with the definition of a higher-priced mortgage loan under Regulation Z, 12 CFR part 1026. Specifically, 12 CFR 1026.35 defines a higher-priced mortgage loan as a closed-end consumer credit transaction secured by the consumer's principal dwelling with an annual percentage rate that exceeds the average prime offer rate for a comparable transaction as of the date the interest rate is set:

(1) By 1.5 or more percentage points, for a loan secured by a first lien with a principal obligation at consummation that does not exceed the limit in effect as of the date the transaction's interest rate is set for the maximum principal obligation eligible for purchase by Freddie Mac;

(2) By 2.5 or more percentage points, for a loan secured by a first lien with a principal obligation at consummation that exceeds the limit in effect as of the date the transaction's interest rate is set for the maximum principal obligation eligible for purchase by Freddie Mac; or

(3) By 3.5 or more percentage points, for a loan secured by a subordinate lien.

(c) Scope. This subpart applies to higher-priced mortgage loan transactions entered into by national banks and their operating subsidiaries, Federal branches and agencies and Federal savings associations and operating subsidiaries of savings associations.

(d) Official Interpretations. Appendix C to this subpart sets out OCC Interpretations of the requirements imposed by the OCC pursuant to this subpart.
