Note 13. Net Income (Loss) Per Share

Our basic net income (loss) per share is computed by dividing the net income (loss) by the number of weighted average common shares outstanding during the period. Our diluted net income (loss) per share is computed by dividing net income (loss) by the weighted average common shares outstanding during the period assuming potentially dilutive common shares of stock options, RSUs and common shares issuable upon conversion of the 2018 Notes and 2020 Notes using the if-converted method.  Common shares issuable upon conversion of the 2018 Notes and 2020 Notes were excluded from the diluted net income (loss) per share computation for all periods presented as their share effect was anti-dilutive.

Net income (loss) per share was calculated as follows for the periods indicated below:
