12 C.F.R. § 1209.9
As provided by section 1311(c) of the Safety and Soundness Act (12 U.S.C. 4511(c) ), the authority of the Director to take action under subtitle A of the Safety and Soundness Act (12 U.S.C. 4611 et seq.) (e.g., the appointment of a conservator or receiver for a regulated entity; entering into a written agreement or pursuing an informal agreement with a regulated entity as the Director deems appropriate; and undertaking other such actions as may be applicable to undercapitalized, significantly undercapitalized or critically undercapitalized regulated entities), or to initiate enforcement proceedings under subtitle C of the Safety and Soundness Act (12 U.S.C. 4631 et seq.), shall not in any way limit the general supervisory or regulatory authority granted the Director under section 1311(b) of the Safety and Soundness Act (12 U.S.C. 4511(b) ). The selection and form of regulatory or supervisory action under the Safety and Soundness Act is committed to the discretion of the Director, and the selection of one form of action or a combination of actions does not foreclose the Director from pursuing any other supervisory action authorized by law.
