Earnings Per Share [Abstract]
LOSS PER SHARE	LOSS PER SHARE Basic loss per share is computed by dividing our net loss by the weighted average number of shares outstanding during the period. Diluted loss per share is computed by dividing our net loss increased by dividends on preferred stock by the weighted average number of shares outstanding and the impact of all dilutive potential common shares, primarily stock options. The dilutive impact of stock options and warrants is determined by applying the “treasury stock” method. In the periods in which their effect would be antidilutive, no effect has been given to outstanding options, warrants or convertible Preferred Stock in the diluted computation. Potentially dilutive shares issuable pursuant to the 2033 Senior Notes (defined in Note 6) were not included in the computation of net loss per share for the three and six months ended June 30, 2015, because their inclusion would be antidilutive. A total of 11,261,582 and 29,132,527 potential shares of Common Stock have been excluded from the calculation of diluted net loss per share for the three months ended June 30, 2015 and 2014, respectively, because their inclusion would be antidilutive. A total of 14,375,502 and 29,503,319 potential shares of Common Stock have been excluded from the calculation of diluted net loss per share for the six months ended June 30, 2015 and 2014, respectively, because their inclusion would be anti-dilutive. During the three months ended June 30, 2015, 2,106,679 Common Stock options and Common Stock warrants to purchase shares of our Common Stock were exercised, resulting in the issuance of 2,106,634 shares of Common Stock. Of the 2,106,679 Common Stock options and Common Stock warrants exercised, 45 shares of Common Stock were surrendered in lieu of a cash payment via the net exercise feature of the agreements. During the six months ended June 30, 2015, 24,168,461 Common Stock options and Common Stock warrants to purchase shares of our Common Stock were exercised, resulting in the issuance of 22,635,661 shares of Common Stock. Of the 24,168,461 Common Stock options and Common Stock warrants exercised, 1,206,654 shares of Common Stock were surrendered in lieu of a cash payment via the net exercise feature of the agreements.

LOSS PER SHARE

Basic loss per share is computed by dividing our net loss by the weighted average number of shares outstanding during the period. Diluted loss per share is computed by dividing our net loss increased by dividends on preferred stock by the weighted average number of shares outstanding and the impact of all dilutive potential common shares, primarily stock options. The dilutive impact of stock options and warrants is determined by applying the “treasury stock” method. In the periods in which their effect would be antidilutive, no effect has been given to outstanding options, warrants or convertible Preferred Stock in the diluted computation.
