Proposed rulemaking (NPR) that would implement section 622 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, which adds a new section 14 to the Bank Holding Company Act of 1956, that establishes a financial sector concentration limit that generally prohibits a financial company from merging or consolidating with, or acquiring, another company if the resulting company's liabilities upon consummation would exceed 10 percent of the aggregate liabilities of all financial companies as calculated under that section. In addition, the proposal would establish reporting requirements for certain financial companies which are necessary to implement section 622.
