Additional 402(v) Disclosure | Pay Versus Performance As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive compensation calculated according to SEC requirements (which includes value related to awards and option awards as if they were vested at the end of the year presented) and certain financial performance of the Company. For further information concerning the Company’s variable pay-for-performance philosophy and how the Company’s aligns executive compensation with the Company’s performance, refer to “Compensation Discussion and Analysis.” Cumulative TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company’s share price at the end and the beginning of the measurement period by the Company’s share price at the beginning of the measurement period assuming $100 initial investment on December 31, 2019. The measurement period for 2020 is January 1, 2020 through December 31, 2020. The measurement period for 2021 is January 1, 2020 through December 31, 2021. The measurement period for 2022 is January 1, 2020 through December 31, 2022. The measurement period for 2023 is January 1, 2020 through December 31, 2023. The measurement period for 2024 is January 1, 2020 through December 31, 2024.The dollar amounts reported represent the amount of GAAP net income reflected in the Company’s audited financial statements for the applicable year. Tabular List As described in greater detail in “Compensation Discussion and Analysis,” the Company’s executive compensation program reflects a variable pay-for-performance philosophy. The metrics that the Company uses for both our long-term and short-term incentive awards are selected based on an objective of incentivizing our NEOs to increase the value of our enterprise for our shareholders. The most important financial performance measures used by the Company to link executive compensation actually paid to the Company’s NEOs, for the most recently completed fiscal year, to the Company's performance are as follows: Description of Relationships Between Compensation Actually Paid and Certain Financial Performance Measure Results In accordance with Item 402(v) of Regulation S-K, the Company is providing the following descriptions of the relationships between certain information presented in the Pay Versus Performance table. |  |  |  |

Non-GAAP Measure Description | Adjusted EBIT is defined as earnings before interest, taxes, and other unusual charges. See the "2024 Company Performance Overview" section for further description as well as Appendix B for reconciliation of non-GAAP to GAAP financial measures. While the Company uses numerous financial and non-financial performance measures for the purpose of evaluating performance for the Company’s compensation programs, the Company has determined that Adjusted EBIT is the financial performance measure that, in the Company’s assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used by the Company to link compensation actually paid to the Company’s NEOs, for the most recently completed fiscal year, to Company performance. |  |  |  |
