12 C.F.R. § 225.141
In orders approving the retention by a bank holding company of a 4(c)(8) subsidiary, the Board has stated that it would permit, without any specific regulatory approval, the formation of a wholly owned subsidiary of an approved 4(c)(8) company to engage in activities that such a company could itself engage in directly through a division or department. (Northwestern Financial Corporation, 65 Federal Reserve Bulletin 566 (1979).) Section 4(a)(2) of the Act provides generally that a bank holding company may engage directly in the business of managing and controlling banks and permissible nonbank activities, and in furnishing services directly to its subsidiaries. Even though section 4 of the Act generally prohibits the acquisition of shares of nonbanking organizations, the Board does not believe that such prohibition should apply to the formation by a holding company of a wholly-owned subsidiary to engage in activities that it could engage in directly. Accordingly, as a general matter, the Board will permit without any regulatory approval a bank holding company to form a wholly-owned subsidiary to perform servicing activities for subsidiaries that the holding company itself could perform directly or through a department or a division under section 4(a)(2) of the Act. The Board believes that permitting this type of subsidiary is not inconsistent with the nonbanking prohibitions of section 4 of the Act, and is consistent with the authority in section 4(c)(1)(C) of the Act, which permits a bank holding company, without regulatory approval, to form a subsidiary to perform services for its banking subsidiaries. The Board notes, however, that a servicing subsidiary established by a bank holding company in reliance on this interpretation will be an affiliate of the subsidiary bank of the holding company for the purposes of the lending restrictions of section 23A of the Federal Reserve Act.
