Net Loss Per Common Share Data Net Loss Per Common Share Data
Basic net loss per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net loss per share is computed using the weighted-average number of common shares and, if dilutive, potential common shares outstanding during the period. The Company’s potential common shares consist of the incremental common shares issuable upon the exercise of stock options, warrants, and to a lesser extent, shares issuable upon the release of RSUs. The dilutive effect of these potential common shares is reflected in diluted earnings per share by application of the treasury stock method.
