Earnings Per Share [Abstract]  
Net Loss Per Share

12. Net Loss Per Share

Basic earnings per share is computed by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net loss for the period by the weighted-average number of common shares outstanding during the period which includes potential dilutive common shares assuming the dilutive effect of outstanding stock options, restricted stock units (including those that are performance-based) and restricted stock awards calculated using the treasury stock method.

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

The Company was in a loss position for the periods presented. Accordingly, basic net loss per share is the same as diluted net loss per share as the inclusion of all potential common shares outstanding would have been anti-dilutive. Prior to application of the treasury stock method, share equivalents (comprising stock options, restricted stock units (including those that are performance-based), ESPP, and restricted stock awards) excluded from the calculations of diluted net loss per share were 25.2 million, 23.1 million and 21.5 million during the years ended December 31, 2018, 2017 and 2016, respectively.
