The C&TD Committee did not consider the pay versus performance disclosure below in making its pay decisions for any of the fiscal years shown.

Kenneth Lane (who served as Interim CEO) was our PEO from January 1, 2022 to May 22, 2022. Peter Vanacker is our PEO since May 23, 2022. The Non-PEO NEOs for whom the average compensation is presented in this table are: (a) for 2023: Michael McMurray, Kenneth Lane, Torkel Rhenman, and Jim Guilfoyle; (b) for 2022: Michael McMurray, Torkel Rhenman, Jeffrey Kaplan, and Jim Guilfoyle; (c) for 2021: Michael McMurray, Kenneth Lane, Torkel Rhenman, and Jim Guilfoyle; and (d) for 2020: Michael McMurray, Kenneth Lane, Torkel Rhenman, Jeffrey Kaplan, and Daniel Coombs.

The comparison assumes $100 was invested, for the period starting December 31, 2019 through the end of the listed year, in the Company and in the S&P 500 Chemicals Index, respectively. Historical stock performance is not necessarily indicative of future stock performance. (4) We determined EBITDA, which is a non-GAAP financial measure, to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEO and Non PEO NEOs in 2023. More information on EBITDA can be found in Appendix A to this proxy statement. We may determine a different financial performance measure to be the most important financial performance measure in future years.
