Regulatory Assets and Liabilities Disclosure [Abstract]

The Bancorp’s and Bank's capital adequacy ratios as of December 31, 2021 and 2020 are presented in the following tables. The decrease in capital ratios as of December 31, 2021 from December 31, 2020 was largely attributable to shares repurchased totaling $40.7 million during 2021. Tier 1 Capital to average assets was also reduced by an increase in cash driven by deposit growth over and above that attributable to the Merger. In addition, as of December 31, 2020, Bancorp's Tier 1 capital included a subordinated debenture, which was not included at the Bank level. On March 15, 2021, Bancorp redeemed in full our last subordinated debenture due to NorCal Community Bancorp Trust II. Partially offsetting those factors, the Merger served to increase capital ratios as the proportion of risk-weighted assets to total assets was lower for ARB.
