^4/ The Peer Group TSR set forth in this table utilizes the S&P U.S. BMI Banks - Western Region Index, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report for the year ended December 31, 2022. The comparison assumes $100 was invested for the period starting December 31, 2019, through the end of the listed year in the Company and in the S&P U.S. BMI Banks - Western Region Index, respectively, with all dividends, if any, being re-invested. Historical stock performance is not necessarily indicative of future stock performance.

^5/ We determined Earnings Per Share (“EPS”) to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEOs and Non-PEO NEOs in 2022. This performance measure may not have been the most important financial performance measure for years 2021 and 2020 and we may determine a different financial performance measure to be the most important financial performance measure in future years.
