Earnings Per Share, Basic and Diluted [Abstract]  
Net Income (Loss) Per Share
Net Income (Loss) Per Share
Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding, while diluted net income (loss) per share reflects the maximum potential dilution that could occur from our stock-based compensation arrangements and the conversion of our outstanding convertible senior notes.
The calculation of the basic and diluted net income (loss) per share was as follows:

As applicable, includes coupon interest, amortization of discount and fees, and other changes in income or loss that would result from the assumed conversion.
(2)
Does not include the anti-dilutive impact of 6,403,559 and 6,256,973 shares, respectively, for the three and six months ended June 30, 2014 due to capped call transactions related to the Convertible Senior Notes due 2017. Such transactions were designed to offset the potential dilution of the notes up to a stock price of approximately $14.11 per share. See Note 11 of Notes to Consolidated Financial Statements in our 2013 Form 10-K.
(3)
For the three and six months ended June 30, 2014, 1,483,800 shares of our common stock equivalents issued under our stock-based compensation arrangements were not included in the calculation of diluted net income per share as of such date because they were anti-dilutive. As a result of our net loss for the three and six months ended June 30, 2013, 39,476,796 and 5,556,916 shares, respectively, of our common stock equivalents issued under our stock-based compensation arrangements and convertible debt were not included in the calculation of diluted net loss per share as of such date because they were anti-dilutive.
