(2) In 2021, the company had two Principal Executive Officers (PEO). Olivier Filliol Patrick Kaltenbach (3) The dollar amounts reported in column (c) represent the “Compensation Actually Paid” to the applicable PEO for the corresponding year. Compensation Actually Paid is calculated pursuant to the requirements of Item 402(v) of Regulation S-K, adjusting Summary Compensation Table totals to reflect equity award valuation changes at certain points over time. It does not reflect dollar amounts actually paid to our PEOs. (4) The dollar amounts reported in column (d) represent the average of the amounts reported for the company’s named executive officers (NEOs) as a group (excluding the PEOs) in the “Total” column of the Summary Compensation Table in each applicable year. The non-PEO NEOs were Shawn P. Vadala, Marc de La Guéronnière, and Gerhard Keller for all periods shown above. For 2020 and 2021, Peter Aggersbjerg, the Head of Divisions during those periods, was also an NEO. For 2022, Richard Wong is also an NEO. (5) The dollar amounts reported in column (e) represent the average amount of “Compensation Actually Paid” to the NEOs as a group (excluding the PEOs) for the corresponding year. Compensation Actually Paid is calculated pursuant to the requirements of Item 402(v) of Regulation S-K, adjusting Summary Compensation table totals to reflect equity award valuation changes at certain points over time. It does not reflect dollar amounts actually paid to our NEOs. The NEOs included for purposes of these calculations are described in footnote 4. (6) Represents the weighted peer group TSR, weighted according to the respective companies’ stock market capitalization at the beginning of each period for which a return is indicated. The peer group used for this purpose is the following published industry index: SIC Code 3826 Index – Laboratory Analytical Instruments. (7) The dollar amounts reported represent the amount of net income reflected in the company’s audited financial statements for the applicable year. (8) 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 non-GAAP earnings per share 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 (including the PEOs), for the most recently completed fiscal year, to company performance. The equity award adjustments for each applicable year include the addition (or subtraction, as applicable) of the following, as shown in the table below: Year Reported Summary Compensation Table Total Reported Value of Year End Year over Year over Compensation PEO – 1 2022 6,223,115 (4,240,354) 5,237,636 (2,567,327) (270,173) 4,382,897 2021 11,708,259 (9,333,307) 13,089,951 0 0 15,464,903 PEO – 2 2021 719,467 0 0 9,720,558 1,317,001 11,757,026 2020 6,301,644 (1,860,176) 1,822,185 8,882,085 2,629,662 17,775,400 The grant date fair value of equity awards represents the total of the amounts reported in the “Stock Awards” and “Option Awards” columns in the Summary Compensation Table for the applicable year. The equity award adjustments for each applicable year include the addition (or subtraction, as applicable) of the following: (i) the year-end fair value of any equity awards granted in the applicable year that are outstanding and unvested as of the end of the year; (ii) the amount of change as of the end of the applicable year (from the end of the prior fiscal year) in fair value of any awards granted in prior years that are outstanding and unvested as of the end of the applicable year; (iii) for awards granted in prior years that vest in the applicable year, the amount equal to the change as of the vesting date (from the end of the prior fiscal year) in fair value. The valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant. (4) The dollar amounts reported in column (d) represent the average of the amounts reported for the company’s named executive officers (NEOs) as a group (excluding the PEOs) in the “Total” column of the Summary Compensation Table in each applicable year. The non-PEO NEOs were Shawn P. Vadala, Marc de La Guéronnière, and Gerhard Keller for all periods shown above.
