Earnings Per Share [Abstract]  
EARNINGS PER SHARE

NOTE 20 EARNINGS PER SHARE

 

Basic and diluted earnings per share data are based on the weighted-average number of common shares outstanding during each period. Unvested but issued restricted stock shares are considered to be outstanding for purposes of calculating the weighted average number of shares outstanding to determine basic and diluted earnings per share and net book value per share.

 

Diluted earnings per share are further adjusted for potential common shares that were dilutive and outstanding during the period. Potential common shares consist of stock options outstanding under incentive plans. The dilutive effect of potential common shares is computed using the treasury stock method. All stock options are assumed to be 100% vested for purposes of the diluted earnings per share computations. The computation of earnings per share for the years ended December 31 are as follows:
