Cash and Cash Equivalents Disclosure [Text Block] | 4. Cash, Cash Equivalents and Restricted Cash The Company manages its cash and cash equivalents, which consist of cash on hand, amounts due from banks, and short-term investments with original maturity of three months or less, based upon the Company’s operating, investment, and financing activities. For the purpose of reporting cash flows, these same accounts are included in cash and cash equivalents. The Company is required to maintain reserves with the Federal Reserve Bank. Reserve requirements are based on a percentage of deposit liabilities. The average reserve balances required were zero and $5.4 million for the three months ended March 31, 2019 and for the year ended December 31, 2018, respectively. As of March 31, 2019 and December 31, 2018, the Bancorp had $4.3 million and $1.8 million on deposit in a cash margin account that serves as collateral for the Bancorp’s interest rate swaps. As of March 31, 2019 and December 31, 2018, the Company held $3.2 million and $7.8 million, respectively, in a restricted escrow account with a major bank for its alternative energy investments. In the unaudited condensed consolidated statement of cash flows, the amounts for the three months ended March 31, 2018 have been corrected in the current year and differ from the previously reported amounts of zero for decrease in interest-bearing deposits, $97.0 million for net cash provided by investing activities, $183.9 million for increase in cash and cash equivalents and $539.8 million for cash and cash equivalents, beginning of period.
