Net Loss per Share Attributable to Common Stockholders
NET LOSS PER SHARE ATTRIBUTABLE TO COMMON STOCKHOLDERS

Basic net loss per share attributable to common stockholders ("EPS") excludes dilution and is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS reflects potential dilution and is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding during the period increased by the number of additional common shares that would have been outstanding if the potential common shares had been issued.
 
The following table reconciles basic and diluted weighted average common shares outstanding for the three and nine months ended September 30, 2013 and 2012 (in thousands except for loss per share):

Stock options and unvested stock of 18.3 million shares and 16.5 million shares representing securities that could potentially dilute basic EPS in the future were not included in the diluted net loss per share computations for the three and nine months ended September 30, 2013, respectively, because they would have been anti-dilutive. Stock options and unvested stock of 5.6 million shares and 3.1 million shares representing securities that could potentially dilute basic EPS in the future were not included in the diluted net loss per share computations for the three and nine months ended September 30, 2012, respectively, because they would have been anti-dilutive.
