(a) In general
Except as provided in subsection (b), a nonbank financial company supervised by the Board of Governors and any subsidiaries of such company (other than any depository institution subsidiary) shall be subject to the provisions of subsections (b) through (n) of section 1818 of this title, in the same manner and to the same extent as if the company were a bank holding company, as provided in section 1818(b)(3) of this title.

(b) Enforcement authority for functionally regulated subsidiaries

(1) Referral
If the Board of Governors determines that a condition, practice, or activity of a depository institution subsidiary or functionally regulated subsidiary of a nonbank financial company supervised by the Board of Governors does not comply with the regulations or orders prescribed by the Board of Governors under this Act, or otherwise poses a threat to the financial stability of the United States, the Board of Governors may recommend, in writing, to the primary financial regulatory agency for the subsidiary that such agency initiate a supervisory action or enforcement proceeding. The recommendation shall be accompanied by a written explanation of the concerns giving rise to the recommendation.

(2) Back-up authority of the Board of Governors
If, during the 60-day period beginning on the date on which the primary financial regulatory agency receives a recommendation under paragraph (1), the primary financial regulatory agency does not take supervisory or enforcement action against a subsidiary that is acceptable to the Board of Governors, the Board of Governors (upon a vote of its members) may take the recommended supervisory or enforcement action, as if the subsidiary were a bank holding company subject to supervision by the Board of Governors.
