Earnings Per Share [Abstract] |
Earnings Per Share | Earnings Per Share Class A and Class B basic earnings per share and Class B diluted earnings per share are calculated under the two-class method. The two-class method allocates earnings to each class of stock based upon its dividend rights. Class B shares are convertible into Class A shares at a conversion ratio of 2,400 to 1. See Note 13, "Capital Stock". Class A diluted earnings per share are calculated under the if-converted method, which reflects the conversion of Class B shares to Class A shares. Diluted earnings per share calculations include the dilutive effect of assumed issuance of stock-based awards under compensation plans that have the option to be paid in stock using the treasury stock method. See Note 11, "Incentive and Deferred Compensation Plans". A reconciliation of the numerators and denominators used in the basic and diluted per-share computations is presented as follows for each class of common stock:
