PAY VERSUS PERFORMANCE

Pay Versus Performance Table

As required by the SEC’s pay versus performance rules (“PVP Rules”), the below Pay Versus Performance table (“PVP Table”) provides information about compensation for this Proxy Statement’s NEOs, as well as certain prior years’ NEOs. The PVP Rules require disclosure from this year’s Proxy Statement and each of our preceding three years of proxy statements (each of 2020, 2021, 2022, and 2023, a “Covered Year”). The PVP Table also provides information about the results for certain financial performance measures during those same Covered Years. In reviewing this information, there are a few important things to consider:

The information in columns (b) and (d) comes directly from this and prior year’s Summary Compensation Tables, without adjustment;

As required by the PVP Rules, we describe the information in columns (c) and (e) as “compensation actually paid” (or “CAP”) to the applicable NEOs, but these CAP amounts do not entirely reflect compensation that our NEOs actually earned for their service in the Covered Years. Instead, CAP reflects a calculation involving a combination of realized pay and realizable or accrued pay;

The PVP Rules require that we use a peer group or index for purposes of total shareholder return (“TSR”) comparisons, and we have continued to use the S&P 400 Industrials index (the “PVP Peer Index”) for this purpose; and

As required by the PVP Rules, we provide information about our PVP Peer Index TSR results and U.S. GAAP net income results (collectively, the “External Measures”) during the Covered Years in the PVP Table, but we did not base any compensation decisions for the NEOs on, or link any NEO pay to, these particular External Measures.

Pursuant to the PVP Rules, the Company is required to designate one financial metric as the “Company-Selected Measure,” or the most important financial measure that demonstrates how the Company sought to link 2023 executive pay to performance. For 2023, the Company has again selected adjusted EPS, as it did for 2022. However, the Company believes that all of the metrics designated in the chart under “Most Important Financial Performance Measures” section on page 77 are important drivers of Company performance that are designed to link executive pay to performance.

Named Executive Officers, Footnote [Text Block]

Richard G. Kyle was our principal executive officer (“PEO”) for each of the Covered Years. In this disclosure, we refer to our NEOs other than Mr. Kyle in any Covered Year as our “Other NEOs” or our “Non-PEO NEOs.” Christopher A. Coughlin, Philip D. Fracassa and Andreas Roellgen were “Other NEOs” for each of the Covered Years. In addition, Hansal N. Patel was an “Other NEO” for 2023, 2022 and 2021, Ronald J. Myers was an “Other NEO” for 2021 and 2020, and Hans Landin was an “Other NEO” for 2022.

Compensation Actually Paid vs. Total Shareholder Return [Text Block]

The PVP Rules require that comparisons be made between certain columns in the PVP Table. Such comparisons can be made graphically without further description, and we have done so below. In accordance with that approach, the following charts show the relationships between our cumulative TSR, the cumulative TSR for the PVP Peer Index reflected in the PVP Table above, and Mr. Kyle’s CAP or Other NEO CAP, as applicable.

Compensation Actually Paid vs. Net Income [Text Block]

The following charts show the relationships between GAAP net income and Mr. Kyle’s CAP or Other NEO CAP, as applicable.

Compensation Actually Paid vs. Company Selected Measure [Text Block]

Lastly, the following charts show the relationships between adjusted EPS and Mr. Kyle’s CAP or Other NEO CAP, as applicable.

Non-GAAP Measure Description [Text Block]

For purposes of this pay versus performance disclosure, adjusted EPS is calculated based on the Company’s adjusted earnings per share as used for external reporting purposes for the Covered Year (net of taxes), further adjusted to exclude the effect of material changes in accounting principles, methods, and/or significant changes in tax law that are not reflected in externally reported diluted earnings per share. See Appendix A for a reconciliation of adjusted EPS as used for external reporting to its most directly comparable GAAP financial measure.
