Included in these “out-of-the-money” warrants are Series A Warrants, Series B Warrants and GLF Equity Warrants which have exercise prices of $57.06, $62.28, and $100.00, respectively. No warrants or restricted stock units, whether in the money or out of the money, are included in our loss per share calculations because the effect of such inclusion is antidilutive.
