Earnings Per Share [Abstract]
Loss Per Share	Loss Per Share The Company computes basic net loss per share by dividing net loss for the period by the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by dividing net 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, stock based compensation awards and other dilutive securities. No such items were included in the computation of diluted loss per share in 2012, 2011 and 2010 because the Company incurred a loss from continuing operations in each of these periods and the effect of inclusion would have been anti-dilutive. The effect of approximately 35 million, 39 million and 52 million shares issuable pursuant to the various series of convertible notes outstanding at December 31, 2012, 2011 and 2010, respectively, have not been included in the computation of diluted loss per share because their inclusion would have been anti-dilutive to the computation. In addition, the effect of the approximately 7 million, 4 million and 3 million stock options, outperform stock options, restricted stock units and warrants outstanding at December 31, 2012, 2011 and 2010, respectively, have not been included in the computation of diluted loss per share because their inclusion would have been anti-dilutive to the computation.
