EARNINGS PER SHARE

Basic EPS is computed based upon the weighted average number of common shares outstanding during each period. Diluted EPS is computed on the basis of the weighted average number of common shares outstanding plus the potential dilutive effect of certain share-based compensation awards as if they were converted into common shares. The dilutive effect of unvested RSU and performance share awards is calculated using the treasury stock method. RSU and performance share awards are included in basic weighted average common shares outstanding as of the date that all necessary vesting conditions have been satisfied. For the years ended December 31, 2017 and 2016, there were no antidilutive share awards excluded from the diluted EPS computation. For the year ended December 31, 2015, there were 1,474 antidilutive share awards excluded from the computation of diluted EPS.

The following table sets forth the components of basic and diluted EPS:
