The Board of Governors of the Federal Reserve System (Board) invited public comment on a proposal that would revise the Board's regulations related to determinations of whether a company has the ability to exercise a controlling influence over another company for purposes of the Bank Holding Company Act or the Home Owners' Loan Act. The proposal would significantly expand the number of presumptions for use in such determinations. By codifying the presumptions in the Board's Regulation Y and Regulation LL, the Board's rules would provide substantial additional transparency on the types of relationships that the Board would view as supporting a determination that one company controls another company. The proposed presumptions generally would be consistent with the Board's historical practice with respect to the types of relationships that raise, or do not raise, significant controlling influence concerns. Several of the proposed presumptions, however, would represent targeted adjustments relative to the Board's historical practice. Finally, the proposal includes various definitions and ancillary rules to ensure that the application of the proposed presumptions is clear, transparent, and consistent.
