The Board of Governors of the Federal Reserve System (Board) is inviting comment on a proposal to establish risk-based capital requirements for depository institution holding companies that are significantly engaged in insurance activities. The Board is proposing a risk-based capital framework, termed the Building Block Approach, that adjusts and aggregates existing legal entity capital requirements to determine an enterprise-wide capital requirement, together with a risk-based capital requirement excluding insurance activities, in compliance with section 171 of the Dodd-Frank Act. The Board is additionally proposing to apply a buffer to limit an insurance depository institution holding company's capital distributions and discretionary bonus payments if it does not hold sufficient capital relative to enterprise-wide risk, including risk from insurance activities. The proposal would also revise reporting requirements for depository institution holding companies significantly engaged in insurance activities.
