Earnings Per Share [Abstract] |
Earnings Per Share | EARNINGS PER SHARE Basic and diluted earnings per share is computed using the two-class method. The two-class method is an earnings allocation formula that determines net income per share for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. Per share amounts are computed by dividing net income from continuing operations attributable to common shareholders by the weighted average shares outstanding during each period. The computations of basic and diluted earnings per share from continuing operations are as follows:
