Subsequent Events [Abstract]
Subsequent Events	Subsequent EventOn July 30, 2020, the Bancorp issued in a registered public offering 350,000 depositary shares, representing 14,000 shares of 4.50% non-cumulative perpetual preferred stock, Series L, for net proceeds of approximately $347 million. Each preferred share has a $25,000 liquidation preference. The preferred stock accrues dividends at an annual rate of 4.50% through but excluding September 30, 2025. From, and including, September 30, 2025 and for each dividend reset period thereafter, dividends will accrue on the Series L preferred stock, on a non-cumulative basis, at a rate equal to the five-year U.S. Treasury rate as of the most recent reset dividend determination date plus 4.215%. Subject to obtaining all required regulatory approvals, on any dividend payment date on or after September 30, 2025, the Bancorp may redeem the Series L preferred stock and the related depositary shares in whole or in part, at 100% of their liquidation preference, plus an amount equal to any declared and unpaid dividends, without accumulation of any undeclared dividends. In addition, the Series L preferred stock and the related depositary shares may be redeemed, subject to obtaining all required regulatory approvals, in whole but not in part, at any time, following the occurrence of a regulatory capital event, at 100% of their liquidation preference, plus an amount equal to any declared and unpaid dividends, without accumulation of any undeclared dividends. The Series L preferred shares are not convertible into Bancorp common shares or any other securities.
