Earnings Per Share

Earnings Per Share

A reconciliation of the numerators and denominators of the basic and diluted earnings per share calculation for income from operations is presented below:

	2012					2011					2010
	Income (Numerator)		Weighted Shares (Denominator)	Per-Share Amount		Income (Numerator)		Weighted Shares (Denominator)	Per-Share Amount		Income (Numerator)		Weighted Shares (Denominator)	Per-Share Amount
	(Amounts and numbers in thousands, except per-share data)
Basic EPS
Income available to common stockholders	$	116,911	54,899	$	2.13	$	191,164	54,825	$	3.49	$	152,198	54,792	$	2.78
Effect of dilutive securities:
Options	0		23			0		20			0		34
Diluted EPS
Income available to common stockholders after assumed conversions	$	116,911	54,922	$	2.13	$	191,164	54,845	$	3.49	$	152,198	54,826	$	2.78

Incremental shares of 415,000, 504,000, and 448,000 for 2012, 2011, and 2010, respectively, were excluded from the computation of the diluted earnings per common shares due to their anti-dilutive effect. Potentially dilutive securities representing approximately 80,000, 103,000, and 93,000 shares of common stock for 2012, 2011, and 2010, respectively, were also excluded from the computation of diluted earnings per common share because their effect would have been anti-dilutive.
