[1] A total of 6,864,011 warrants outstanding as of December 31, 2022 (a total of 7,085,073 warrants and 6,148,004 warrants outstanding as of December 31, 2021 and 2020, respectively) can potentially dilute earnings per share in the future but have not been included in the calculation of diluted earnings per share because they are antidilutive for the periods presented. Similarly, 575,000 convertible senior notes which can potentially be converted into 3,456,785 ordinary shares, can potentially dilute earnings per share in the future but have not been included in the calculation of diluted earnings per share because they are antidilutive for 2022.
