Earnings Per Share [Abstract]  
EARNINGS PER SHARE
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 and unexercised stock options 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 three and nine months ended September 30, 2016 and 2015, there were no antidilutive share awards excluded from the computation.

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