Description of Regulatory Requirements, Prompt Corrective Action     On September 17, 2019, the federal bank regulators issued a final rule required by the EGRRCPA that permits qualifying banks and bank holding companies that have less than $10 billion of assets, like the Company and the Bank, to elect to be subject to a 9% leverage ratio that would be applied using less complex leverage calculations (commonly referred to as the community bank leverage ratio or “CBLR”). Under the rule, which  became effective January 1, 2020, banks and bank holding companies that opt into the CBLR framework and maintain a CBLR of greater than 9% would not be subject to other risk-based and leverage capital requirements under the Basel III Capital Rules and would be deemed to have met the well capitalized ratio requirements under the “prompt corrective action” framework.
