	Year Ended December 31,
	2021		2020		2019
Net loss attributable to common stockholders, basic and diluted	$	(110,048)	$	(107,908)	$	(120,199)

Diluted earnings per share (“EPS”) includes the dilutive effect of common stock equivalents and is computed using the weighted-average number of common stock and common stock equivalents outstanding during the reporting period. Diluted EPS for the years ended December 31, 2021, 2020, and 2019 excluded common stock equivalents because the effect of their inclusion would be anti-dilutive or would decrease the reported loss per share.

The following table sets forth securities outstanding that could potentially dilute the calculation of diluted earnings per share:
