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. For diluted earnings per share, the dilutive impact of stock options, warrants and, for the years ended December 31, 2016 and 2015, conversion options of the 2033 Senior Notes is determined by applying the “treasury stock” method. For the year ended December 31, 2017, the 2033 Senior Notes have been considered using the “if converted” 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. The following table sets forth the computation of basic and diluted earnings (loss) per share:
