Net Loss per Share [Abstract]

Net Loss per Share

Note 13. Net Loss per Share

Basic net loss per share amounts for each period presented were computed by dividing net loss by the weighted-average number of shares of common stock outstanding. Diluted net loss per share for each period presented was computed by dividing net loss plus interest on dilutive convertible senior notes by the weighted-average number of shares of common stock outstanding during each period plus all additional common shares that would have been outstanding assuming dilutive potential common shares had been issued for dilutive convertible senior notes and other dilutive securities.

Dilutive potential common shares for dilutive convertible senior notes are calculated based on the “if-converted” method. Under the “if-converted” method, when computing the dilutive effect of convertible senior notes, the numerator is adjusted to add back the amount of interest and debt issuance costs recognized in the period and the denominator is adjusted to add the amount of shares that would be issued if the entire obligation is settled in shares. As of June 30, 2011, the Company’s outstanding indebtedness consisted of its 4.0% convertible senior notes due 2016.

Dilutive potential common shares also include the dilutive effect of the common stock underlying in-the-money stock options and are calculated based on the average share price for each period using the treasury stock method. Under the treasury stock method, the exercise price of an option, the average amount of compensation cost, if any, for future service that the Company has not yet recognized when the option is exercised, are assumed to be used to repurchase shares in the current period.

The computations for basic and diluted net loss per share were as follows:

Under the “if-converted” method, 5.8 million potential common shares relating to the 2016 Notes were not included in diluted net loss per share for the three and six months ended June 30, 2011 because their effect would be anti-dilutive. Diluted net loss per share does not include the effect of $3.9 million and $3.4 million stock-based awards that were outstanding during the three and six months ended June 30, 2011, respectively and $5.5 million and $4.9 million stock-based awards that were outstanding during the three and six months June 30, 2010, respectively, because their effect would have been anti-dilutive.
