The Board of Governors of the Federal Reserve System (Board) is inviting comment on an advance notice of proposed rulemaking (ANPRM) regarding approaches to regulatory capital requirements for depository institution holding companies significantly engaged in insurance activities (insurance depository institution holding companies), and nonbank financial companies that the Financial Stability Oversight Council (FSOC or Council) has determined will be supervised by the Board and that have significant insurance activities.  The Board is inviting comment on two approaches to consolidated capital requirements for these institutions: An approach that uses existing legal entity capital requirements as building blocks for insurance depository institution holding companies and a simple consolidated approach for systemically important insurance companies.
