The number of shares used to calculate basic earnings per share includes the weighted-average units credited to employees and directors under the deferred compensation plans. Additionally, nonvested units are also included in the computation of basic weighted average shares when the requisite service period has been completed. Accordingly, included in basic shares are weighted-average units of 0.5million in the three months and 0.5million in the nine months endedSeptember 30,2014, and 0.6million in the three months and 0.6 million in the nine months endedSeptember 30,2013.
