Cash and Cash Equivalents [Abstract]
CASH AND DUE FROM BANKS	CASH AND DUE FROM BANKSThe Federal Reserve Act requires that banks maintain cash reserve balances with the Federal Reserve Bank based principally on the type and amount of their deposits. At its option, the Company maintains additional balances to compensate for clearing and safekeeping services. The average balance maintained in 2021 was $491.9 million and in 2020 was $236.3 million.

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.
