Net Income (Loss) Per Share

Note 9 — Net Income (Loss) Per Share

Basic net income (loss) per share is calculated based on the weighted-average number of common shares outstanding during the periods presented. Diluted net income (loss) per share is calculated based on the weighted-average number of common shares outstanding, including potential dilutive securities. For all periods presented in the accompanying Condensed Consolidated Statements of Operations, the net income (loss) available to common stockholders is equal to the reported net income (loss).

The calculation of diluted net income per share for the three months ended September 30, 2014 includes the weighted average of potentially dilutive securities, which consists of approximately 4.7 million stock options.

For periods in which we have generated a net loss, basic and diluted net loss per share are the same due to the requirement to exclude potentially dilutive securities which would have an anti-dilutive effect on net loss per share. The weighted average of these potentially dilutive securities for the three months ended September 30, 2013 consisted of approximately 9.7 million stock options, and for the nine months ended September 30, 2014 and 2013 consisted of approximately 10.1 million and 13.0 million, respectively, stock options.
