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, 2015, 2014, and 2013:

	Year Ended December 31,
	2015			2014			2013
Net loss	$	(50,785	)	$	(45,719	)	$	(62,134	)
Weighted average shares—basic	64,882,417			64,708,163			60,729,128
Net loss per share—basic	$	(0.78	)	$	(0.71	)	$	(1.02	)
Weighted average shares—diluted	64,882,417			64,708,163			60,729,128
Net loss income per share—diluted	$	(0.78	)	$	(0.71	)	$	(1.02	)

The below outstanding securities were excluded from the above calculation of net loss per share because their impact would have been anti-dilutive due to net loss per share, for the years ended, as summarized below:
