Numerator:
Net loss	$	(272,072	)	$	(176,782	)	$	(228,626	)
Net loss attributable to non-controlling interest		(1,643	)		(448	)		(4,194	)
Net loss attributable to American Well Corporation	$	(270,429	)	$	(176,334	)	$	(224,432	)
Denominator:
Weighted-average common shares outstanding, basic and diluted		274,249,749			254,068,942			99,044,312
Net loss per share attributable to common stockholders, basic and diluted	$	(0.99	)	$	(0.69	)	$	(2.27	)

The Company’s potential dilutive securities, which include stock options, convertible preferred stock and unvested restricted stock units, have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share. Therefore, the weighted-average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. The Company excluded the following potential common shares equivalents presented based on amounts outstanding at each period end, from the computation of diluted net loss per share attributable to common stockholders for the periods indicated because including them would have had an anti-dilutive effect:
