Earnings Per Share [Abstract] |
Earnings Per Share | Earnings Per Share The Company reports basic and diluted earnings per share. Basic earnings per share is computed by dividing net income attributable to shareholders of the Company by the weighted average number of common shares outstanding during the reported period. Diluted earnings per share reflect the potential dilution related to equity-based incentives using the treasury stock method. The calculation and reconciliation of basic and diluted earnings per share for the years ended December 31 (in thousands, except per share data) follows:
