The Board of Governors of the Federal Reserve System (Board) is adopting a final rule to make several revisions to its rule regarding risk-based capital surcharges for U.S.-based global systemically important bank holding companies (GSIB surcharge rule). The final rule modifies the GSIB surcharge rule to provide that a bank holding company subject to the rule should continue to calculate its method 1 score and method 2 score under the rule annually using data reported on the firm's Banking Organization Systemic Risk Report (FR Y- 15) as of December 31 of the previous calendar year. In addition, the final rule clarifies that a bank holding company subject to the GSIB surcharge rule must calculate its method 2 score using systemic indicator amounts expressed in billions of dollars.
