(4) | These two columns show the total shareholder return, or TSR, assuming $100 was invested on December 31, 2019 in both the Company’s common stock and our selected peer group, the KBW Regional Banking Index, and assumes the reinvestment of all cash dividends prior to any tax effect and retention of all stock dividends. The selected peer group and associated TSR is the line-of-business index we used for purposes of Item 201(e) of Regulation S-K.
(5) | This column provides our net income for each year presented.
(6) | This column represents the financial performance measure that we believe is the most important measure (that is not otherwise disclosed in the table) that we use to align compensation actually paid to our NEOs in 2023 with our performance. Operating return on tangible common equity, or operating ROTCE, is a non-GAAP financial measure used in our MIP. For a description of how operating ROTCE is calculated, see “Compensation Discussion and Analysis—Short-Term Incentive Compensation and Discretionary Bonus—Incentive Award Payouts and Discretionary Bonus—Corporate Performance.”
