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. The effect of approximately 28 million and 35 million shares issuable pursuant to the various series of convertible notes outstanding at March 31, 2013 and March 31, 2012, 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 6 million and 4 million stock options, outperform stock appreciation rights ("OSOs"), restricted stock units and warrants outstanding at March 31, 2013 and March 31, 2012, respectively, have not been included in the computation of diluted loss per share because their inclusion would have been anti-dilutive to the computation.
