Earnings Per Share [Abstract]

Earnings Per Share

Per Share

The Company computes basic earnings per share by dividing net income or 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 or 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 and 28 million shares issuable pursuant to the various series of convertible notes outstanding at June 30, 2014 and June 30, 2013, respectively, have not been included in the computation of diluted earnings per share because their inclusion would have been anti-dilutive to the computation. The effect of approximately 5 million stock options, outperform stock appreciation rights ("OSOs"), and restricted stock units ("RSUs") outstanding at June 30, 2014 have been included in the computation of diluted earnings per share. The effect of approximately 6 million stock options, OSOs and RSUs outstanding at June 30, 2013 have not been included in the computation of diluted earnings per share because their inclusion would have been anti-dilutive to the computation.
