4.     Net Loss per Share

Basic net loss per share is computed by dividing net loss by the weighted average number of shares of common stock of the Company outstanding during the period. Diluted net loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period plus the impact of dilutive securities using the treasury stock method, to the extent that they are not anti-dilutive.

The following table presents the calculation of basic and diluted net loss per share for the Company’s common stock:

The following potential common shares, presented based on amounts outstanding for the three months ended March 31, 2020 and 2019, were excluded from the calculation of diluted net loss per share for the periods indicated because including them would have had an anti-dilutive effect.
