NOTES:
| (1) | Mr. Meissner was the CEO for each of 2020, 2021, 2022 and 2023.
| (2) | SEC rules require certain adjustments must be made to the Summary Compensation Table totals to determine “compensation actually paid” as reported in the Pay versus Performance Table. Compensation actually paid (“CAP”) does not necessarily represent cash and/or equity value transferred to the applicable Named Executive Officer without restriction, but rather is a value calculated under applicable SEC rules. In general, CAP is calculated as Summary Compensation Table total compensation adjusted to include the fair market value of equity awards as of December 31 of the applicable year or, if earlier, the vesting date (rather than the grant date), as well as an adjustment subtracting the change in pension value as of December 31 and adding the actuarially determined service cost for services rendered by the Named Executive Officer, if applicable, during the covered fiscal year. The following table details these adjustments:
