The comparison assumes $100 was invested for the period starting December 31, 2019 through December 31 of the applicable fiscal year in each of the Company’s common stock and the NQ US Pharma Index. All dollar values assume reinvestment of the pre-tax value of dividends paid by companies included in the NQ US Pharma Index. The historical stock price performance of our common stock shown is not necessarily indicative of future stock price performance. 5 Pursuant to Item 402(v) of Regulation S-K, we determined our stock price to be the most important financial performance measure used to link Company performance to Compensation “Actually Paid” to our PEO and other NEOs in 2022. This performance measure may not have been the most important financial performance measure for years 2021 and 2020 and we may determine a different financial performance measure to be the most important such measure in future years. | ||||
