Earnings Per Share [Abstract]  
Net Income (Loss) Per Share Net Income (Loss) Per Share
          Basic net income (loss) per common share is computed by dividing the net income (loss) relevant to the common stockholders by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per common share uses the same net income (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, 2022 and 2021, (in thousands, except for per share data):
