Schedule of Compliance with Regulatory Capital Requirements under Banking Regulations

The following tables present actual and required capital ratios as of December 31, 2017 and 2016 for the Company and the Bank under the Basel III Capital Rules. The minimum required capital amounts presented include the minimum required capital levels as of December 31, 2017 and 2016 based on the phase-in provisions of the Basel III Capital Rules and the minimum required capital levels as of January 1, 2019 when the Basel III Capital Rules have been fully phased-in, in each case, including the capital conservation buffer required during such period. Capital levels required to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Capital Rules.
