Basis of Financial Statement Presentation [Abstract]

Revision of EPS Presentation

The Company determined in the quarter ended June 30, 2012 that although the Class A and Class B common stock have different dividend rates, the Company had not applied the two-class method when calculating earnings per share (“EPS”) separately for the Class A and Class B common stock. This resulted in immaterial revisions to previously reported basic EPS for Class A and Class B common stock and diluted EPS for the Class B common stock as summarized below:

For the quarter ended September 30, 2011:

	As previously reported		As revised
Basic EPS – Class A common	$	0.83	$	1.01
Basic EPS – Class B common	$	0.83	$	0.50
Diluted EPS – Class A common	$	0.83	$	0.83
Diluted EPS – Class B common	$	0.83	$	0.50

For the nine months ended September 30, 2011:

	As previously reported		As revised
Basic EPS – Class A common	$	2.26	$	2.75
Basic EPS – Class B common	$	2.26	$	1.38
