Earnings Per Share [Abstract]  
Earnings (Loss) Per Share
EARNINGS (LOSS) PER SHARE
Basic earnings (loss) per share is computed by dividing our net income (loss) by the weighted average number of shares outstanding during the period. For diluted earnings per share, the dilutive impact of stock options, warrants and, for periods in 2016, conversion options of the 2033 Senior Notes 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 the potentially dilutive shares issuable pursuant to the 2033 Senior Notes (defined in Note 6) in the dilutive computation.
A total of 1,016,090 and 1,636,706 potential shares of Common Stock have been excluded from the calculation of diluted net loss per share for the three and nine months ended September 30, 2017, respectively, because their inclusion would be antidilutive. A full presentation of diluted earnings per share has not been provided because the required adjustments to the numerator and denominator resulted in diluted earnings per share equivalent to basic earnings per share.
During the three months ended September 30, 2017, no Common Stock options and Common Stock warrants to purchase shares of our Common Stock were exercised.

During the three months ended September 30, 2016, 660,921 Common Stock options and Common Stock warrants to purchase shares of our Common Stock were exercised, resulting in the issuance of 658,357 shares of Common Stock.
