Earnings Per Share [Abstract]  
Earnings Per Share
EARNINGS PER SHARE

Earnings per share amounts for the Company are presented using two different computations.  Basic earnings per share excludes dilutive effects of certain securities or contracts, such as stock options, and is computed by dividing income available to each class of common stockholders on an as if distributed basis by the weighted-average number of common shares outstanding for the period.  Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock, that then shared in the distributed earnings of each class of common stock. Stock options not included in the weighted-average number of diluted shares, because such shares would have been anti-dilutive, were immaterial.  U.S. GAAP requires a two-class presentation for the Company’s two classes of common stock (Note 6, Transactions with Controlling Stockholder).  Accordingly, the earnings per share for both Class A and Class B are presented.  The following table sets forth the computations of basic and diluted earnings per share.
