Net Loss Per Share

Net Loss Per Share

3 Months Ended

Mar. 31, 2021

Basic net loss per common share is computed by dividing the net loss relevant to the common stockholders by the weighted average number of common shares outstanding during the period. Diluted net loss per common share uses the same net loss divided by the sum of the weighted average number of shares of common stock outstanding during the period, plus dilutive effects of options, performance and restricted stock units outstanding during the period calculated using the treasury method and the potential dilutive effects of preferred stocks (if any) calculated using the if-converted method.

The table below shows the calculations for the three months ended March 31, 2021 and 2020, (in thousands, except for per share data):
