(a) | For 2023, Gregory D. Johnson was the PEO and the non-PEOs included Greg Henslee, David O’Reilly, Brad Beckham, Brent Kirby, Jeremy Fletcher, and Scott R. Ross.
(b) | For 2022, Gregory D. Johnson was the PEO and non-PEO NEOs included Greg Henslee, David O’Reilly, Brad Beckham, Jeremy Fletcher, Brent Kirby, and Tom McFall.
(c) | For 2021, Gregory D. Johnson was the PEO and non-PEO NEOs included Greg Henslee, David O’Reilly, Brad Beckham, Brent Kirby, Tom McFall, and Jeff M. Shaw.
(d) | For 2020, Gregory D. Johnson was the PEO and non-PEO NEOs included Greg Henslee, David O’Reilly, Tom McFall, and Jeff M. Shaw.
(e) | In November of 2023, in connection with Mr. Johnson’s planned retirement in January of 2024, his stock option award granted in February of 2023 was cancelled and substituted with a cash-based award with an equivalent grant-date fair value of the cancelled stock option award equal to $1,475,000, which is included in the “Bonus” column of the “Summary Compensation Table” for the year ended December 31, 2023. Such cash-based award was earned by and paid to Mr. Johnson in early 2024, following his retirement, and such cancellation and substitution was recommended by the Human Capital and Compensation Committee and approved by the Board. Therefore, Mr. Johnson is shown as having no equity-based compensation awarded in 2023.
(f) | The amounts in the following table represent each of the amounts deducted from and added to the equity award values, as presented in the “Summary Compensation Table,” for the PEO for the applicable year for purposes of computing the “compensation actually paid” amounts appearing in the “Compensation Actually Paid to PEO” column of the “Pay Versus Performance” table. There was no change in pension values for the years ended December 31, 2023, 2022, 2021, and 2020, as the Company did not offer a pension plan.

Greg Henslee and David O’Reilly, in consultation with the Human Capital and Compensation Committee, are excluded from participation in the annual cash incentive compensation plan pursuant to their responsibilities of providing strategic direction and guidance to the Company and their limited role in the Company’s day-to-day operational activities and, therefore, excluded from these financial performance measures.

- Definition The estimated measure of the percentage by which a share price is expected to fluctuate during a period. Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period. + References Reference 1: http://www.xbrl.org/2003/role/disclosureRef -Topic 718 -SubTopic 10 -Name Accounting Standards Codification -Section 50 -Paragraph 2 -Subparagraph (f)(2)(ii) -Publisher FASB -URI https://asc.fasb.org//1943274/2147480429/718-10-50-2 + Details
