BASIC AND DILUTED EARNINGS PER COMMON SHARE

Shares used in basic (loss) earnings per share are computed using the weighted-average number of common shares outstanding during each period. Shares used in diluted (loss) earnings per share include the dilutive effect of unvested restricted stock under the Company’s Stock Plan using the treasury stock method. For the three months ended March 31, 2018, diluted loss per share equals basic loss per share as the assumed vesting of restricted stock would have an anti-dilutive effect. At March 31, 2018 and 2017, there were no outstanding stock options under the Company's Stock Plan.
