8. Net loss per share of Common Stock

The following table summarizes the computation of basic and diluted net loss per share of the Company (in thousands, except per share data):

	Three Months Ended						Nine Months Ended
	September 30,						September 30,
	2017			2016			2017			2016
Net loss	$	(49,788	)	$	(27,335	)	$	(116,107	)	$	(73,684	)
Weighted-average shares used to compute basic and diluted net loss per share		35,680			29,574			35,336			29,495
Basic and diluted net loss per common share	$	(1.40	)	$	(0.92	)	$	(3.29	)	$	(2.50	)

Basic net loss per share is computed by dividing the net loss by the weighted-average number of common shares outstanding for the period. Diluted net loss per share is computed by dividing the net loss per common share by the weighted-average number of common shares and dilutive common stock equivalents outstanding for the period, determined using the treasury-stock method and the as-if converted method, for convertible securities, if inclusion of these is dilutive. Because the Company has reported a net loss for all periods presented, diluted net loss per share is the same as basic net loss per common share for those periods.

The following potentially dilutive securities outstanding at the end of the periods presented have been excluded from the computation of diluted shares outstanding as the effect would be anti-dilutive:

	September 30,
	2017		2016
Options to purchase common stock		4,650,559		4,430,010
Restricted stock units		936,135		481,385
