The Board’s Regulation XX - Concentration Limit (12 CFR Part 251) implements section 14 of the Bank Holding Company Act of 1956 (BHC Act), which establishes a financial sector concentration limit that generally prohibits a financial company from merging or consolidating with, or otherwise acquiring, another company if the resulting company’s liabilities upon consummation would exceed 10 percent of the aggregate liabilities of all financial companies (a covered acquisition). Under section 14 of the BHC Act and Regulation XX, a financial company means (1) an insured depository institution, (2) a bank holding company, (3) a savings and loan holding company, (4) any other company that controls an insured depository institution, (5) a nonbank financial company designated by the Financial Stability Oversight Council (Council) for supervision by the Board, or (6) a foreign bank or company that is treated as a bank holding company for purposes of the BHC Act. Regulation XX includes certain reporting requirements that apply to financial companies, and the FR XX-1 report collects information from certain financial companies that do not otherwise report consolidated financial information to the Board or another Federal banking agency.
