Earnings Per Share [Abstract] |
Earnings Per Common Share | Earnings Per Common Share Earnings per common share (“EPS”) are computed by dividing net income by the weighted average number of shares of common stock (basic) plus common stock equivalents outstanding (diluted) during the period. Common stock equivalents consist of stock options, which have been included in the calculation of weighted average shares outstanding using the treasury stock method, unvested shares, performance share units, and shares issuable in connection with certain deferred compensation agreements (“DCUs”). ASC 260 “Earnings Per Share” provides that all outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends participate in undistributed earnings with common shareholders. If awards are considered participating securities, the Company is required to apply the two-class method of computing basic and diluted earnings per share. The Company has determined that its outstanding unvested shares are participating securities. Accordingly, earnings per common share are computed using the more dilutive of the treasury stock method and the two-class method prescribed by ASC 260. For purposes of calculating diluted EPS, net income attributable to common shareholders was reduced by $0.1 million and $0.2 million for the three months ended June 30, 2015 and 2014, respectively; and $0.4 million and $0.7 million for the six months ended June 30, 2015 and 2014, respectively. Basic weighted average shares reconciles to diluted weighted average shares as follows:
| Three Months Ended June 30, |  | Six Months Ended June 30,
| 2015 |  | 2014 |  | 2015 |  | 2014
Basic weighted average common shares outstanding | 77,466 |  |  | 80,106 |  |  | 77,731 |  |  | 80,317 |
Dilutive effect of stock options, unvested shares, performance share units and DCUs | 831 |  |  | 1,043 |  |  | 845 |  |  | 1,045 |
Diluted weighted average common shares outstanding | 78,297 |  |  | 81,149 |  |  | 78,576 |  |  | 81,362 |
Options to purchase approximately 0.9 million and 0.5 million shares of common stock for both the three and the six months ended June 30, 2015 and 2014, respectively, were not included in the computation of diluted EPS because the effect of their inclusion would be antidilutive.
