Cash And Cash Equivalents [Abstract]
Restrictions on Cash	Note 2. Restrictions on Cash To comply with Federal Reserve regulations, the Bank is required to maintain certain average cash reserve balances. The daily average cash reserve requirements were $0 as of December 31, 2021 and December 31, 2020. On March 15, 2020, the Federal Reserve reduced reserve requirement ratios to zero percent effective March 26, 2020. This action eliminated reserve requirements for all depository institutions. Prior to the change, reserve requirement ratios on net transactions accounts differed based on the amount of net transactions accounts at the depository institution. A certain amount of net transaction accounts, known as the "reserve requirement exemption amount," was subject to a reserve requirement ratio of zero percent. Net transaction account balances above the reserve requirement exemption amount and up to a specified amount, known as the "low reserve tranche," were subject to a reserve requirement ratio of 3 percent. Net transaction account balances above the low reserve tranche were subject to a reserve requirement ratio of 10 percent. The reserve requirement exemption amount and the low reserve tranche are indexed each year pursuant to formulas specified in the Federal Reserve Act

The entire disclosure for cash and cash equivalent footnotes, which may include the types of deposits and money market instruments, applicable carrying amounts, restricted amounts and compensating balance arrangements. Cash and equivalents include: (1) currency on hand (2) demand deposits with banks or financial institutions (3) other kinds of accounts that have the general characteristics of demand deposits (4) short-term, highly liquid investments that are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Generally, only investments maturing within three months from the date of acquisition qualify.
