Earnings Per Share [Abstract] |
NET LOSS PER SHARE | NET LOSS PER SHARE The Company calculates basic and diluted net loss per share by dividing the net loss by the weighted-average number of common shares outstanding during the period. Diluted net loss per share is the same as basic net loss per share, since the effects of potentially dilutive securities are antidilutive. The following table presents the computation of basic and diluted net loss per share:
