Earnings Per Share [Abstract] |
Earnings Per Share | Earnings Per Share Basic earnings per share (“basic EPS”) is computed by dividing net income by the weighted average number of common shares outstanding for the reporting period. Diluted earnings per share (“diluted EPS”) gives effect to all dilutive potential shares outstanding resulting from employee stock options, restricted stock units, performance share units and stock appreciation rights (“SARs”) during the period. The following table sets forth the computation of basic and diluted earnings per share for the three and nine months ended September 30, 2013 and 2014.
