The following table provides a reconciliation of the numerator and denominator used in computing basic and diluted net loss attributable to common stockholders per common share:

	Three Months Ended June 30,				Six Months Ended June 30,
(in thousands, except per share amounts)	2020		2019		2020		2019
Numerator:
Net loss attributable to common stockholders	$	(52,492)	$	(84,551)	$	(141,440)	$	(204,850)
Denominator:
Weighted average common shares outstanding — basic and diluted	257,973,329		238,089,824		257,548,623		225,848,013

Dilutive common stock equivalents would include the dilutive effect of common stock options, convertible debt units, RSUs, and warrants for common stock equivalents. Potentially dilutive common stock equivalents were excluded from the diluted earnings per share denominator for all periods because of their anti-dilutive effect.

The table below presents potential shares of common stock that were excluded from the computation as they were anti-dilutive using the treasury stock method:

	As of June 30,
(in thousands)	2020	2019
Options to purchase common stock	18,414	17,849
Convertible notes	462	462
Outstanding warrants, convertible to common stock	2,555	2,555
Unvested restricted stock units	7,484	5,885
