Note 11 – (Loss) earnings per share

Basic (loss) earnings per share is computed using the weighted average number of common shares outstanding during the period and income available to common stockholders. Diluted (loss) earnings per share is computed using the weighted average number of common shares outstanding during the period plus the dilutive effect of all potential shares of common stock including common stock issuable pursuant to stock options, warrants, and restricted stock units.

For the three and six months ended June 30, 2020 and 2019, the (loss) earnings per share was calculated as follows (in thousands, except earnings per share and related share data):

For the six months ended June 30, 2020 and 2019, 1.4 million and 1.0 million stock options, warrants and restricted share units were determined to be anti-dilutive and were therefore excluded from the calculation of diluted earnings per share, respectively.
