Net Loss Per Share

9 Months Ended

Sep. 30, 2016

Basic net loss per share attributed to common shares is computed by dividing the net loss attributable to common shares for the period by the weighted average number of common shares outstanding during the period.

Diluted net loss per share attributed to common shares is computed by dividing the net loss attributable to common shares for the period by the weighted average number of common and potential common shares outstanding during the period, if the effect of each class of potential common shares is dilutive. Potential common shares include RSUs and incremental shares of common stock issuable upon the exercise of stock options, conversion of warrants, and the impact of convertible senior notes.

A summary of the net loss per share for the three and nine months ended September 30, 2016 and 2015 is as follows (in thousands, except per share amounts):
