Adjustment To PEO Compensation, Footnote [Text Block]

The amounts reported represent the amount of “compensation actually paid” to Mr. Becker, 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 Mr. Becker during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to Mr. Becker’s total compensation as reported in the SCT for each year to determine the compensation actually paid to Mr. Becker:

(a)The amounts shown in this column reflect the total grant date fair value of equity awards granted to Mr. Becker for the applicable year, which represents the total of the amounts reported in the “Stock Awards” and “Stock Option Awards” columns of 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) for any awards granted in the applicable year that are outstanding and unvested as of the end of the year, the year-end fair value of those awards; (ii) for any awards granted in prior years that are outstanding and unvested as of the end of the applicable year, the amount of change as of the end of the applicable year (from the end of the prior fiscal year) in fair value of those awards; (iii) for any awards that were granted and became vested in the same applicable year, the fair value of those awards as of the vesting date; (iv) for any awards granted in prior years that vested in the applicable year, the amount equal to the change in fair value of those awards as of the vesting date (from the end of the prior fiscal year); (v) for any awards granted in prior years that failed to meet the applicable vesting conditions during the applicable year, a deduction for the amount equal to the fair value of those awards as of 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 (which were none for each of the applicable years). The valuation assumptions used to calculate fair values did not materially differ from those disclosed as of the grant date of the equity awards. The amounts deducted or added in calculating the equity award adjustments are as follows:


Year	Year End Fair Value of Outstanding and Unvested Equity Awards Granted in the Applicable Year	Year over Year Change in Fair Value of Outstanding Equity Awards Granted in Prior Years	Fair Value as of Vesting Date of Equity Awards Granted and Vested in the Applicable Year	Year over Year Change in Fair Value of Equity Awards Granted in Prior Years that Vested in the Applicable Year	Fair Value at the End of the Prior Year of Equity Awards that Failed to Meet Vesting Conditions in the Applicable Year	Total Equity Award Adjustments

Compensation Actually Paid Versus TSR

Compensation Actually Paid vs. Net Income [Text Block]

Compensation Actually Paid Versus Net Income

29% of the target value of total compensation awarded to the CEO and 41% of the target value of total compensation awarded to the other NEOs (in each case, for 2022) consists of amounts determined under the Company short-term incentive compensation program.

Compensation Actually Paid vs. Company Selected Measure [Text Block]

Compensation Actually Paid Versus Return on Equity

As demonstrated by the following graph, the amount of compensation actually paid to Mr. Becker and the average amount of compensation actually paid to the Company’s NEOs as a group (excluding Mr. Becker) is generally aligned with the Company’s ROE over the three years presented in the Pay Versus Performance Table. While 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 ROE 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 Company performance. The Company utilizes ROE for purposes of setting performance goals in the Company’s short-term incentive compensation program on both an absolute and relative basis, as well as for setting goals for the performance-based RSUs, relative to peers, that are awarded to the NEOs. As described in more detail in the “Executive Officers and Compensation—Compensation Discussion and Analysis” section, the Company targets that approximately 90% of the target value of total compensation awarded to the CEO and 81% of the target value of total compensation awarded to the other NEOs is considered “at-risk” through the short-term and long-term incentive programs.

Total Shareholder Return Vs Peer Group [Text Block]

Company TSR Versus Peer Group TSR

As demonstrated by the following graph, the Company’s cumulative TSR over the three-year period presented in the Pay Versus Performance Table was $91.67, while the cumulative TSR of the peer group presented for this purpose, the Nasdaq Bank Index, was $114.85 during the same period. While the Company’s cumulative TSR outperformed the Nasdaq Bank Index during the first two years presented in the Pay Versus Performance Table, which correlates to the compensation actually paid to the PEO and other NEOs, the cumulative TSR for the full three years is below the index peer group which is represented in the decrease in compensation actually paid (as computed in accordance with Item 402(v) of Regulation S-K) in 2022. For more information regarding the Company’s performance and the companies that the Compensation and Human Capital Committee considers when determining compensation, refer to “Executive Officers and Compensation—Compensation Discussion and Analysis.”

Return on Equity ("ROE")

Total Shareholder Return (TSR) is calculated on a cumulative basis by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company’s share price at the end and the beginning of the measurement period by the Company’s share price at the beginning of the measurement period.

Measure [Axis]: 2

Relative TSR (the Company’s TSR as compared to a peer group established by the Compensation and Human Capital Committee)

Peer Group Shareholder Return represents the weighted peer group TSR, weighted according to the respective companies’ stock market capitalization at the beginning of each period for which a return is indicated. The peer group used for this purpose is the following published industry index: Nasdaq Bank Index as of December 31, 2022.

PEO [Member] | Adjustment, Equity Awards Reported Value [Member]

Return on Equity (ROE) is defined as the percentage equal to Net Income divided by the Company's common stockholders' equity, in each case, as reflected in the Company's audited financial statements for the applicable year. While 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 Return on Equity 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 company performance.
