For the three months ended March 31, 2020 there were 1,034,084 stock options excluded from the computation of diluted earnings per share because the inclusion of such stock options would result in an antidilutive effect and 27,085 shares were excluded from the computation of diluted earnings per share amounts because the loss attributable to common stockholders was a loss, not income. For the three months ended March 31, 2021, no stock options were excluded from the computation of diluted earnings per share.
