Per Share Data	Per Share Data Basic net loss per common share is calculated by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per common share adjusts basic net loss per common share, computed using the treasury stock method, for the effects of potentially dilutive common shares, if the effect is not antidilutive. Outstanding options and restricted stock units (exclusive of participating securities) that had no effect on our computation of dilutive weighted average number of shares outstanding as their effect would have been antidilutive were approximately 118 million shares and 83 million shares as of the periods ended December 31, 2016 and 2015, respectively, in addition to 62 million total shares issuable under warrants, of which 55 million relate to shares issuable under the warrant held by SoftBank.
