Calculation of Basic and Diluted Net Income (Loss) per Share

The following table presents information necessary to calculate net income (loss) per share for the three and nine month periods ended September 30, 2015 and 2014 as well as potentially dilutive securities excluded from the weighted average number of diluted common shares outstanding because their inclusion would have been anti-dilutive (in thousands, except per share amounts):
