Earnings Per Share [Abstract]  
Earnings Per Share Earnings Per Share
We report our earnings per share using the two-class method. The income per share for each class of common stock is calculated assuming 100% of our earnings are distributed as dividends to each class of common stock based on the contractual rights of the classes.
The Common Stock of the Company has a preferential dividend rate of at least 105% of the dividend paid on the Class A Common Stock. The Class A Common Stock, which has ten votes per share as opposed to one vote per share for the Common Stock (on all matters other than the election of directors), may be converted at any time on a one-for-one basis into Common Stock at the option of the holder of the Class A Common Stock.
