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, RSUs and LTIP RSUs under the Company’s Stock Plan using the treasury stock method. For the year ended December 31, 2018, diluted loss per share equals basic loss per share, as the assumed vesting of restricted stock and restricted stock units would have an anti-dilutive effect. As of December 31, 2018 and 2017, there were no outstanding stock options under the Company's Stock Plan. See Note 14, "Stock Compensation Plan," for information on the LTIP RSUs.
