3.For each Covered Year, our total shareholder return was calculated as the yearly percentage change in our cumulative total shareholder return on our common stock, par value $0.05 per share, measured as the quotient of (a) the sum of (i) the cumulative amount of dividends for a period beginning with our closing price on The NASDAQ Global Select Market on December 31, 2019 through and including the last day of the Covered Year (each one-year, two-year, and three-year period, the “Measurement Period”), assuming dividend reinvestment, plus (ii) the difference between our closing stock price at the end versus the beginning of the Measurement Period, divided by (b) our closing share price at the beginning of the Measurement Period. Each of these yearly percentage changes was then applied to a deemed fixed investment of $100 at the beginning of each Measurement Period to produce the Covered Year-end values of such investment as of the end of 2022, 2021 and 2020, as applicable. Because Covered Years are presented in the table in reverse chronological order (from top to bottom), the table should be read from bottom to top for purposes of understanding cumulative returns over time. |  |
