Earnings per share

Earnings per share

8. Earnings per share

        Basic earnings per share is computed by dividing net loss available to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings per share is computed by dividing net loss available to common stockholders by the weighted-average number of common shares plus the effect of dilutive potential common shares outstanding during the period.

        The following table sets forth the computation of basic and diluted earnings per share for common stockholders:

Net loss per share

​	​	​	​	​	​	​	​	​	​	​
Net loss per share:
Basic and diluted		$	(5.07	)*	$	(2.97	)*	$	(5.18	)*
​	​	​	​	​	​	​	​	​	​	​
​	​	​	​	​	​	​	​	​	​	​

*           For the years ended December 31, 2015, 2014, and 2013, the Company experienced a net loss and therefore did not report any dilutive share impact.

        The following table shows historical dilutive common share equivalents outstanding, which are not included in the above historical calculation, as the effect of their inclusion is anti-dilutive during each period.

		As of December 31,
		2015			2014			2013
Stock Options			4,826,477			3,432,972			2,095,592
