The Bank is also required to comply with a Capital Conservation Buffer (“CCB”). The CCB is designed to establish a capital range above minimum capital requirements and impose constraints on dividends, share buybacks and discretionary bonus payments when capital levels fall below prescribed levels. The minimum CCB is 2.500%. The CCB for the Bank at September 30, 2019 was 5.21%. Set forth below is a summary of the Bank’s compliance with banking regulatory capital standards.
