| Additional 402(v) Disclosure [Text Block] | For each of 2022, 2021 and 2020, our TSR was calculated as the yearly percentage change in our cumulative total shareholder return on our common stock, 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 Stock Market on December 31, 2019 through and including the last day of the fiscal year covered (the “Measurement Period”), assuming dividend reinvestment, plus (ii) the difference between our stock price at the end and the beginning of the Measurement Period, divided by (b) our stock 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 the Measurement Period to produce the year-end values of such investment as of the end of 2022, 2021 and 2020, as applicable. Because fiscal 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.Net income is calculated in accordance with GAAP.Adjusted EBITDA is calculated as set forth in Appendix A. | | |
