Loss Per Common Share

The computation of basic net loss per share is based on the weighted average number of common shares outstanding for the three and nine-month periods ended September 30, 2017 and September 30, 2016. Diluted net loss per share gives effect to stock awards, stock options and restricted stock units using the treasury stock method, unless the impact is anti-dilutive. Diluted net loss per share as of September 30, 2017 does not include 1,853,637 unvested stock awards, 1,565,906 stock options and 152,266 warrants, as their effect was anti-dilutive. Diluted net loss per share as of September 30, 2016 does not include 26,147 stock awards, 56,987 stock options and 152,266 warrants, as their effect was anti-dilutive.
