​ Certificates of deposit are issues by U.S. banks with original maturities greater than three months. Each certificate of deposit is fully FDIC-insured. The Corporation maintains cash and cash equivalents with certain financial institutions in excess of the FDIC insurance limit. Historically, C&N Bank has been required to maintain reserves against deposit liabilities in the form of cash and balances with the Federal Reserve Bank of Philadelphia. The reserves are based on deposit levels, account activity, and other services provided by the Federal Reserve Bank. In March 2020, the Federal Reserve Board reduced reserve requirements for U.S. banks to 0%. Accordingly, C&N Bank had no required reserves at September 30, 2021 and December 31, 2020.
