| Compensation Actually Paid vs. Total Shareholder Return [Text Block] | Compensation Actually Paid and TSR As shown in the above graph, over the past three years, the amount of compensation actually paid to the CEO and the average amount of compensation actually paid to other NEOs as a group (excluding the CEO) is aligned with the Company's TSR over the past three years presented in the table. The actual value that our CEO and other NEOs could realize from these equity awards is greater. | | |
| Compensation Actually Paid vs. Net Income [Text Block] | Compensation Actually Paid and Net Income As shown in the above graph, the amount of compensation actually paid to the CEO and the average amount of compensation actually paid to other NEOs as a group (excluding the CEO) is aligned with the Company's net income over the past three years presented in the table. | | |
| Compensation Actually Paid vs. Company Selected Measure [Text Block] | Compensation Actually Paid and Core EPS, excluding PPP As shown in the above graph, the amount of compensation actually paid to the CEO and the average amount of compensation actually paid to other NEOs as a group (excluding the CEO) is aligned with the Company’s core earnings per share, excluding PPP (a non-GAAP measure), over the past three years presented in the table. | | |

| Additional 402(v) Disclosure [Text Block] | The dollar amounts represents the amount of "compensation actually paid" to the Company’s principal executive officer (" PEO "), as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual amount of compensation earned by or paid to the PEO during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to the PEO’s total reported compensation for each year in the Summary Compensation Table to determine the compensation actually paid: (a) The grant date fair value of equity awards consists of RSUs and stock options, and represents the total of the amounts reported in the "Stock Awards" and "Option Awards" columns, respectively, in the Summary Compensation Table for the applicable year. (b) The equity award adjustments for each applicable year include the addition (or subtraction, as applicable) of the following: (i) the year-end fair value of any equity awards granted in the applicable year that are outstanding and unvested as of the end of the year; (ii) the amount of change as of the end of the applicable year (from the end of the prior fiscal year) in fair value of any awards granted in prior years that are outstanding and unvested as of the end of the applicable year; (iii) for awards that are granted and vest in same applicable year, the fair value as of the vesting date; (iv) for awards granted in prior years that vest in the applicable year, the amount equal to the change in fair value as of the vesting date (from the end of the prior fiscal year); (v) for awards granted in prior years that are determined to fail to meet the applicable vesting conditions during the applicable year, a deduction for the amount equal to the fair value at the end of the prior fiscal year; and (vi) the dollar value of any dividends or other earnings paid on stock or option awards in the applicable year prior to the vesting date that are not otherwise reflected in the fair value of such award or included in any other component of total compensation for the applicable year. The valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant based on the assumptions and methodologies set forth in the consolidated financial statements included in NOTE 15 - SHARE-BASED COMPENSATION PLANS of our Annual Report on Form 10-K for the year ended December 31, 2022. (c) There were no pension benefits adjustments for the years in the table. The uncertainty caused by high inflation, higher rates and continued stimulus by the government will keep high risk of uncertainty and volatility in 2023. Accordingly, the Leadership Development and Compensation Committee has chosen additional financial performance measures to achieve a much stronger balance sheet and dramatically improve the quality of the Company's deposit franchise in 2023 including the growth in our non-interest-bearing demand deposits and CET1 ratio. Refer to "Compensation Discussion and Analysis", "Compensation Plan for 2022". Analysis of the Information Presented in the Pay versus Performance Table The Company’s executive compensation program reflects our pay-for-performance philosophy. While the Company utilizes several performance measures to align executive compensation with Company performance, all of those Company measures are not presented in the Pay Versus Performance Table above. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s performance measures with compensation that is actually paid (as computed in accordance with Item 402(v) of Regulation S-K) for a particular year. In accordance with Item 402(v) of Regulation S-K, the Company is providing the following descriptions of the relationships between information presented in the Pay Versus Performance Table. | | |

| Measure Name | Core EPS, excluding PPP (Non-GAAP) (1) | | |
| Non-GAAP Measure Description [Text Block] | Core EPS, excluding PPP is a company selected, non-GAAP measure. The Company's reasons for the use of the non-GAAP measure and a detailed reconciliation between the non-GAAP measure and the comparable GAAP amount are included in Appendix C . Although the Company uses numerous financial and non-financial performance measures for the purpose of evaluating performance for the Company's compensation programs, the Company has determined that Core EPS, excluding PPP is the financial performance measure that, in the Company's assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used by the Company to link compensation actually paid to the Company's NEOs, for the most recently completed fiscal year, to the Company performance. | | |
