[1] Beginning in 2022, with the adoption of ASU 2020-06, we have applied the if-converted method for calculating diluted earnings per share (see Note 1).

[2] Due to the net losses for the year ended December 31, 2020, RSUs representing approximately 589,000 shares, respectively, have been excluded from the number of shares used in calculating diluted net income (loss) per share, as their inclusion would be antidilutive.

[3] The number of shares used in calculating diluted net income per share for the year ended December 31, 2020, excluded potential dilution from the 2.75% Convertible Notes converting into shares of common stock since the average stock price did not exceed $31.47. (See Note 14 for further details).
