Earnings Per Share [Abstract]  
NET LOSS PER SHARE
10 NET LOSS PER SHARE

Basic loss per share is based on the weighted-average number of common shares outstanding during each period. Diluted loss per share is based on basic shares as determined above plus common stock equivalents. The computation of diluted net loss per share does not assume the issuance of common shares that have an anti-dilutive effect on net loss per share. For the three months ended March 31, 2021 and 2020 all warrants, options and convertible debt securities were excluded from the computation of diluted net loss per share.


Dilutive shares which could exist pursuant to the exercise of outstanding stock instruments and which were not included in the calculation because their affect would have been anti-dilutive for the three months ended March 31, 2021 and 2020 are as follows:
