Earnings Per Share Computations Table
The following table provides EPS computations for the three months and nine months ended September 30, 2016 and 2015. Basic EPS is calculated by dividing earnings attributable to common stock by the weighted-average number of common shares outstanding for the period. Diluted EPS includes the potential dilution of common stock equivalent shares that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.

Includes 572 and 504 average fully vested restricted stock units held in our Deferred Compensation Plan for the three months ended September 30, 2016 and 2015, respectively, and 565 and 486 of such units for the nine months ended September 30, 2016 and 2015, respectively. These fully vested restricted stock units are included in weighted-average common shares outstanding for basic EPS because there are no conditions under which the corresponding shares will not be issued.
(2)
Reflects the prospective adoption of ASU 2016-09 as of January 1, 2016, as we discuss in Note 2. Prior to the adoption, the dilutive effect of stock options, restricted stock awards and restricted stock units was reduced by excess tax benefits assumed to be used to repurchase shares on the open market.
