Net Loss Per Share

NET LOSS PER SHARE

Net loss per share was computed by dividing net loss by the weighted average number of common shares outstanding for the years ended December 31, 2019, 2018, and 2017:

	Year Ended December 31,
	2019			2018			2017
Net loss	$	(112,689	)	$	(120,741	)	$	(92,189	)
Weighted average shares—basic and diluted	110,585,768			103,305,911			85,115,592
Net loss per share—basic and diluted	$	(1.02	)	$	(1.17	)	$	(1.08	)

The below outstanding securities were excluded from the above calculation of net loss per share because their impact under the “treasury stock method” and “if-converted method” would have been anti-dilutive due to our net loss per share for the years ended December 31, 2019, 2018, and 2017, as summarized below:
