Pay vs Performance Disclosure |  |  |  |
Pay vs Performance Disclosure, Table | Pay versus Performance Pursuant to SEC rules, the Pay versus Performance disclosure below details compensation for the Company’s CEO and average compensation for the other named executives, both as reported in the Summary Compensation Table and with certain adjustments to reflect compensation actually paid to such individuals in each of the Company’s fiscal years 2023, 2022, 2021, and 2020. The disclosure also provides information on the Company’s TSR, as well as that of the S&P 500 Health Care Index, on a cumulative basis over the same four fiscal years. The Company’s Net Income is shown for the past four fiscal years, as well as non-GAAP EPS which we consider another important performance measure. A detailed discussion of the Compensation Committee’s decisions regarding the compensation awarded to the named executives for 2023 can be found in the section of this Proxy Statement entitled “Compensation Discussion and Analysis”. Please see Appendix A to this Proxy Statement for reconciliation of our GAAP EPS to non-GAAP EPS for 2014-2023.

​ (1) SEC rules specify adjustments from the Summary Compensation Table totals to calculate compensation actually paid to the CEO and other named executives. These adjustments are detailed in the table below titled “Reconciliation of Summary Compensation Table Total to Compensation Actually Paid” but do not necessarily reflect cash or equity value transferred to the executive outright. ​ (2) For 2020, 2021 and 2022, our named executives were: Mr. Foster, Mr. David Smith (former Chief Financial Officer), Mr. Barbo, Ms. Girshick and Mr. LaPlume. Ms. Pease became a named executive in 2022 when she assumed the role of Chief Financial Officer. For 2023, our named executive officers are: Mr. Foster, Ms. Pease, Mr. Barbo, Ms. Girshick and Mr. LaPlume. ​ (3) TSR was measured for 2020 for the period from December 27, 2019 to December 24, 2020; for 2021 for the period from December 27, 2019 to December 23, 2021; for 2022 for the period from December 27, 2019 to December 30, 2022; and for 2023 for the period from January 2, 2023 to December 29, 2023. The peer group is the S&P 500 Health Care Index. ​ Reconciliation of Summary Compensation Table Total to Compensation Actually Paid The table below details the adjustments made to the total compensation paid as disclosed in the Summary Compensation to arrive at the compensation actually paid for our CEO and the average for our other named executives:
