Earnings Per Share [Abstract]

Earnings Per Share

Per Share

The Company computes basic earnings per share by dividing net income (loss) for the period by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed by dividing the net income (loss) for the period by the weighted average number of shares of common stock outstanding during the period and including the dilutive effect of common stock that would be issued assuming conversion or exercise of outstanding convertible notes and stock-based compensation awards.

The effect of approximately 18 million shares issuable pursuant to the various series of convertible notes outstanding at September 30, 2014 has not been included in the computation of diluted earnings per share for the three and nine months ended September 30, 2014 because their inclusion would have been anti-dilutive to the computation. The effect of approximately 4 million and 5 million stock options, outperform stock appreciation rights ("OSOs"), and restricted stock units ("RSUs") outstanding at September 30, 2015 and 2014, respectively, have been included in the computation of diluted earnings per share.
