Denominator:
Weighted average common shares outstanding — basic and diluted		20,576,838		20,126,672		20,512,254		6,975,386
Net loss per share attributable to common stockholders — basic and diluted	$	(0.48)	$	(0.30)	$	(1.51)	$	(4.66)

The Company’s potentially dilutive securities, which include stock options, shares of convertible preferred stock, warrants to purchase shares of convertible preferred stock and warrants to purchase shares of common stock, have been excluded from the computation of diluted net loss per share attributable to common stockholders, as the effect would be to reduce the net loss per share attributable to common stockholders. 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, 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:
