The amounts reflected in this column were NOT paid to the employees in 2025.  Instead, these amounts will become vested in 2026 and 2027 and will be contingent on the employee’s future service performance.
(2)
The compensation actually paid to the PEO and Non-PEO Named Executive Officers is calculated by using the Total Compensation per the Summary Compensation Table, reducing it by the RSA grant date fair value, and increasing it by the fair value of the RSAs as of December 31, 2025, as shown in the previous tables.
(3)
The peer group used is the S&P 600 Regional Banks, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report on Form 10-K for the year ended December 31, 2025. (Total Stockholder Return, or “TSR”, represents the cumulative total stockholder return during each measurement period and is calculated by dividing the sum of (i) the difference between the share price at the end and the beginning of the measurement period, plus (ii) the cumulative amount of dividends paid on the stock for the measurement period, assuming dividend reinvestment, by the share price at the beginning of the measurement period. Each amount assumes that $100 was invested in common stock on December 31, 2021, and dividends were reinvested for additional shares.) The comparison assumes $100 was invested for the period starting December 31, 2021, through the end of the listed year in the Company and in the S&P 600 Regional Banks index, respectively. Historical stock performance is not necessarily indicative of future stock performance.

Compensation Actually Paid vs. Total Shareholder Return [Text Block]
TSR is not directly tied to any performance goals; however, it affects the RSAs issued in any one year.  Accordingly, a substantial portion of the compensation actually paid to our Named Executive Officers is aligned with our TSR. Our TSR is strong relative to the TSR of the peer group and has exceeded our average peer group by $12.21, or 8.29%, from December 31, 2020 to December 31, 2025.
