Note 11.  Net Loss per Share

Net loss per share has been computed by dividing net loss by the weighted-average number of shares outstanding during the period. Diluted per share amounts reflect potential dilution from the exercise or conversion of securities into common stock. The Company’s capital structure includes common stock options and common stock warrants, all of which have been excluded from net loss per share calculations as they are antidilutive, as follows:
