EARNINGS (LOSS) PER SHARE

3 Months Ended

Mar. 31, 2022

Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of shares outstanding during the period. For periods in which the Company reports net income, diluted net earnings per share is determined by using the weighted average number of common and dilutive common equivalent shares outstanding during the period, unless the effect is antidilutive.

The calculations of shares used to compute loss per share were as follows (in thousands):


	Three months ended
		March 31, 2022	March 31, 2021
Weighted average shares outstanding - basic		149,167	145,936
Potential dilutive common shares		—	—
Weighted average shares outstanding - diluted		149,167	145,936

Options to purchase the Company's common stock and unvested restricted and performance-based stock units aggregating 8.4 million shares and 12.8 million shares have not been included in the computation of diluted earnings per share for the three months ended March 31, 2022 and 2021, respectively, because their effect would have been antidilutive.
