Earnings per Share

12 Months Ended

Dec. 31, 2020

Earnings per ShareBasic EPS excludes dilution and is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock using the treasury stock method. Potentially dilutive securities (consisting primarily of the Convertible Notes calculated using the if-converted and treasury stock method and warrants, stock options and RSUs calculated using the treasury stock method) are excluded from the diluted EPS computation in loss periods and when the applicable exercise price is greater than the market price on the period end date as their effect would be anti-dilutive.

The calculation of basic and diluted earnings per share was as follows (in thousands, except share and per share data):


	Year Ended December 31,
	2020		2019
Net loss attributable to common stockholders	$	(114,119)	$	(40,486)
Weighted-average common shares outstanding	96,111,547		78,322,496
Basic and diluted net loss per share	$	(1.19)	$	(0.52)

For the year ended December 31, 2020, the computation of diluted EPS excluded 26,180,766 shares, primarily related to Convertible Notes, warrants, stock options and RSUs for which the effect would have been anti-dilutive.
