(i) Represents the grant date fair value of equity-based awards granted each year and the change in actuarial present value of the individuals' accumulated benefit under all defined benefit pension plans. (ii) Reflects the value of equity calculated in accordance with the SEC methodology for determining Compensation Actually Paid for each year shown, including the fair value of equity awards granted in the covered year at the end of the covered year; year-over-year changes in the fair value of equity awards granted in prior years that are still outstanding and unvested as of the covered year-end, including: •2018, 2019, 2020, 2021, and 2022 RSA/RSU awards; •2018, 2019, 2020, 2021, and 2022 PSA/PSU awards; •January 2013 Option Grants; and year-over-year changes in fair value of equity awards granted in prior years that vested in the covered year, including: •2017, 2018, and 2019 RSA/RSU awards; •2017, 2018, and 2019 PSA/PSU awards; •January 2013 Option Grants. Service based awards are valued based on the stock price as of the end of each fiscal year or on vest date, as appropriate. Performance based awards are valued based on the stock price at the end of each fiscal year or on vest date, as appropriate, and are subject to a performance factor applied based upon the likelihood of the award to payout at vesting. This performance factor is based the the Company's Long Term Incentive performance factors described in more detail on page 40. Stock options are valued using Black-Scholes valuation at each relevant year end and vest date. (iii) No pension values are included in the additions to the Summary Compensation Table total to arrive at Compensation Actually Paid as there have been no service costs associated with the pension plan since it was frozen in 2005 as described under Pension Benefits on page 49. (3)The non-principal executive officer (PEO) named executive officers (NEOs) reflected in columns (d) and (e) represent the following individuals for 2020 and 2021: Messrs. Steven E. Nell; Stacy C. Kymes; Scott B. Grauer; and Norman P. Bagwell. Following Mr. Kymes' move to Chief Executive Officer effective January 1, 2022, the non-PEO NEOs reflected in columns (d) and (e) represent the following individuals for 2022: Steven E. Nell; Scott B. Grauer; Marc C. Maun; and Norman P. Bagwell. (4)The Total Shareholder Return Peer group is the KBW Regional Banking Index, which is the same peer group used in the Shareholder Return Performance Graph on page 19 of the Company's Annual Report on Form 10-K for the year ending December 31, 2022. Tabular Disclosure of Most Important Measures to Determine FY2022 Compensation Actually Paid The items listed below represent the most important financial metrics the Company used to determine CAP for FY2022 as further described in our Compensation Discussion and Analysis (CD&A) within the sections titled "Annual Incentive Bonus" (page 38) and "Long-Term Incentive Compensation" (page 40). Although absolute earnings per share is not used for the purposes of calculating executive incentive, it is a one-year measure which directly impacts two- and three-year relative earnings per share peer group percentile rank, which each drive meaningful portions of executive pay.
