Earnings Per Share [Abstract]

Net Loss Per Share

14. Net Loss Per Share

Basic earnings per share is computed by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net loss for the period by the weighted-average number of common shares outstanding during the period which includes potential dilutive common shares assuming the dilutive effect of outstanding stock options, restricted stock units (including those that are performance-based) and restricted stock awards calculated using the treasury stock method.

The following table sets forth the computation of basic and diluted earnings per share:

	Year Ended December 31,
(in thousands, except per share amounts)	2020			2019			2018
Numerator:
Net loss	$	(91,581	)	$	(73,859	)	$	(154,740	)
Denominator:
Weighted-average shares outstanding - basic and diluted		139,887			131,568			107,900
Net loss per common share - basic and diluted:	$	(0.65	)	$	(0.56	)	$	(1.43	)

The Company was in a loss position for the periods presented. Accordingly, basic net loss per share is the same as diluted net loss per share as the inclusion of all potential common shares outstanding would have been anti-dilutive. Prior to application of the treasury stock method, share equivalents (comprising restricted stock units (including those that are performance-based), stock options, restricted stock awards, and shares issuable under the ESPP) excluded from the calculations of diluted net loss per share were 23.0 million, 23.8 million and 25.2 million during the years ended December 31, 2020, 2019 and 2018, respectively.
