(1)    The CEO for each of 2022, 2021, and 2020 was James A. Brock.
(2)    The other named executive officers for each applicable year are as follows:
•     2022: Mitesh B. Thakkar, Martha A. Wiegand, Kurt R. Salvatori, and John M. Rothka
•     2021: Mitesh B. Thakkar, Martha A. Wiegand, Kurt R. Salvatori, and John M. Rothka
•     2020: Martha A. Wiegand, Kurt R. Salvatori, and James McCaffrey
(3)    SEC rules require certain adjustments be made to the Summary Compensation Table totals to determine “compensation actually paid” as reported in the Pay versus Performance Table. “Compensation actually paid” does not necessarily represent cash and/or equity value transferred to the applicable named executive officer without restriction, but rather is a valuation calculated under applicable SEC rules. In general, “compensation actually paid” is calculated as summary compensation table total compensation adjusted to (a) include the value of any pension benefit (or loss) attributed to the past fiscal year, including on account of any amendments adopted during such year; and (b) include the fair market value of equity awards as of December 31, 2022 or, if earlier, the vesting date (rather than the grant date) and factor in dividends and interest accrued with respect to such awards. For purposes of the pension valuation adjustments shown below, there was no prior service cost to report. In addition, for purposes of the equity award adjustments shown below, no equity awards were cancelled due to failure to meet vesting conditions, no equity awards were granted and vested in the same year, and there are no dividends or interest accrued to report.
