Basic loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted loss per share reflects the potential dilution assuming common shares were issued upon the exercise of outstanding options and the proceeds thereof were used to purchase outstanding common shares. Dilutive potential common shares include outstanding stock options, warrants and restricted stock and performance share awards. For the years ended December 31, 2016, 2017 and 2018, the basic and diluted weighted-average shares outstanding are the same, since the effect from the potential exercise of outstanding stock options, warrants and vesting of restricted stock and performance shares totalling 1,896,000, 1,831,000 and 1,788,000, respectively, would have been anti-dilutive due to the loss.
