Additional 402(v) Disclosure
PAY VERSUS PERFORMANCE (PVP) DISCLOSURES
The following pages of our Proxy Statement provide disclosures about the relationship between (a) the "compensation actually paid" to our principal executive officer ("PEO") and the average "compensation actually paid" to our non-PEO NEOs, as defined under SEC disclosure rules, and (b) certain financial performance measures of the Company for the fiscal years listed below. These disclosures have been prepared in accordance with Item 402(v) of Regulation S-K under the Exchange Act (the "Pay versus Performance Rules") and do not necessarily reflect how the Committee evaluates compensation decisions. "Compensation actually paid" does not reflect the value of cash or shares of the Company's common stock received by a NEO during the year, but rather is an amount calculated under SEC rules to include, among other things, year-over-year changes in the value of unvested equity-based awards. To calculate "compensation actually paid", adjustments were made to the amounts reported in the Summary Compensation Table for the applicable year in accordance with the disclosure rules. For the purposes of calculating "compensation actually paid", the fair value of equity awards is calculated using the same valuation methodologies used to calculate the grant date fair value of awards in accordance with FASB ASC Topic 718 for the purposes of the Summary Compensation Table, and, where applicable, may incorporate adjustments for year-end forecasted attainment levels for performance achievement goals. As a result of the calculation methodology required by the SEC, the amounts shown below as "compensation actually paid" differ from the compensation actually received by our NEOs, and from the decisions of the Committee described in the Compensation Discussion and Analysis above.
Mr. Halftermeyer received a negative change in pension value in 2024; according to SEC guidelines, the value is incorporated into Summary Compensation Table calculations but is not included for purposes of aggregating the Compensation Actually Paid.For the relevant year, represents the cumulative total shareholder return (TSR) for the Company for the measurement period. TSR assumes that $100 was invested on December 31, 2020, and that dividends were reinvested when and as paid.Reflects “Net Income” as reported in the Company’s Annual Reports on Form 10-K for each of the years reported.No dividends are paid or accrued on any unvested equity awards.
The four items listed below represent the most important performance metrics we use to determine Compensation Actually Paid for 2024 as further described in our Compensation Discussion and Analysis with the section titled “Executive Compensation Earned” (see page 47). The definitions of these metrics are set forth in Exhibit A to the Proxy Statement.
Relationship between “Compensation Actually Paid” and Performance
The graphs that follow show the relationship of “compensation actually paid” to our PEOs and other named executive officers in 2021, 2022, 2023, 2024 and 2025 to (1) the TSR for both the Company and our compensation peer benchmarking groups, (2) the Company’s net income, and (3) the Company’s adjusted EBITDA. For the purposes of these graphs, an averaged "compensation actually earned" is used for Messrs. Higgins and Kleveland for 2023.
