Earnings Per Share Reconciliation [Abstract] |
Computation Of Basic Earnings And Diluted Earnings Per Share | The following table summarizes the computations of basic earnings per share (“Basic EPS”) and diluted earnings per share (“Diluted EPS”). Basic EPS is computed as net income divided by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur from common shares issuable through stock-based compensation plans including stock options, restricted stock units, market-based restricted stock units, performance-based restricted stock units, and ESPP purchase rights using the treasury stock method.
