The Board is adopting this final rule to implement section 618 of the Dodd-Frank Wall Street Reform and Consumer Protection Act ("Dodd-Frank Act" or "Act"), which permits nonbank companies that own at least one registered securities broker or dealer, and that are required by a foreign regulator or provision of foreign law to be subject to comprehensive consolidated supervision, to register with the Board and subject themselves to supervision by the Board. The final rule outlines the requirements that a securities holding company must satisfy to make an effective election, including filing the appropriate form with the responsible Reserve Bank, providing all additional required information, and satisfying the statutory waiting period of 45 days or such shorter period the Board determines appropriate.
