| Tabular List, Table | Tabular List of Company Performance Measures For the fiscal year ended December 31, 2023, Adjusted EBIT is identified as the most important financial performance measure in linking “compensation actually paid” to our performance; Adjusted EBIT was the only performance measure used in our annual cash incentive program in 2023. The other most important financial performance measure used in 2023 in linking “compensation actually paid” to our performance is ROIC; ROIC was the only performance measure used in our PSU awards granted in 2023. We only used these two financial measures in our 2023 incentive plans, so only those two are being disclosed in the following table.
