Reconciliation Income (Loss) from Continuing Operations, Income (Loss) from Discontinued Operations and Net Income (Loss) and Weighted Average Common Shares Outstanding for Calculating Basic Net Earnings (Loss) Per Share

The following is a reconciliation of the Company’s income from continuing operations, income (loss) from discontinued operations and net income and weighted-average common shares outstanding for calculating basic earnings per share:

	Three Months Ended September 30,					Nine Months Ended September 30,
Basic	2014			2013		2014			2013
Income from continuing operations	$	156,608		$	149,909	$	335,895		$	309,723
Income (loss) from discontinued operations, net of tax		(4,423	)		756		(6,288	)		(152	)
Net income		152,185			150,665		329,607			309,571
Less: Distributed earnings to common shareholders		55,664			50,007		161,439			99,929
Less: Distributed earnings to participating securities		17			19		49			41
Undistributed earnings		96,504			100,639		168,119			209,601
Undistributed earnings allocated to common shareholders		96,478			100,598		168,070			209,520
Undistributed earnings allocated to participating securities		26			41		49			81
Total income from continuing operations available to     common shareholders, basic	$	156,565		$	149,849	$	335,797		$	309,601
Total income available to common shareholders, basic	$	152,142		$	150,605	$	329,509		$	309,449
Weighted-average common shares outstanding, basic		178,992			177,965		178,800			177,671
Basic earnings per share: (a)
Income from continuing operations	$	0.87		$	0.84	$	1.88		$	1.74
Income (loss) from discontinued operations, net of tax	$	(0.02	)	$	0.00	$	(0.04	)	$	(0.00	)
Net income	$	0.85		$	0.85	$	1.84		$	1.74

(a) Earnings per share amounts are computed independently for income from continuing operations, income (loss) from discontinued operations and net income. As a result, the sum of per-share amounts from continuing operations and discontinued operations may not equal the total per-share amount for net income.

Reconciliation of Income (Loss) from Continuing Operations, Income (Loss) from Discontinued Operations and Net Income (Loss) and Weighted Average Common Shares Outstanding for Calculating Diluted Earnings (Loss) Per Share

The following is a reconciliation of the Company’s income from continuing operations, income (loss) from discontinued operations and net income and weighted-average common shares outstanding for calculating diluted earnings per share:

	Three Months Ended September 30,					Nine Months Ended September 30,
Diluted	2014			2013		2014			2013
Total income from continuing operations available to     common shareholders, basic	$	156,565		$	149,849	$	335,797		$	309,601
Income (loss) from discontinued operations, net of tax		(4,423	)		756		(6,288	)		(152	)
Total income available to common shareholders, basic		152,142			150,605		329,509			309,449
Undistributed earnings for participating securities		26			41		49			81
Total income from continuing operations available to     common shareholders, diluted	$	156,591		$	149,890	$	335,846		$	309,682
Total income available to common shareholders, diluted	$	152,168		$	150,646	$	329,558		$	309,530

Weighted-average common shares outstanding, diluted		179,948			179,154		179,723			178,906
Diluted earnings per share (a)
Income from continuing operations	$	0.87		$	0.84	$	1.87		$	1.73
Income (loss) from discontinued operations, net of tax	$	(0.02	)	$	0.00	$	(0.03	)	$	(0.00	)
Net income	$	0.85		$	0.84	$	1.83		$	1.73

(a) Earnings per share amounts are computed independently for income from continuing operations, income (loss) from discontinued operations and net income. As a result, the sum of per-share amounts from continuing operations and discontinued operations may not equal the total per-share amount for net income.

The following potentially dilutive common stock equivalents were not included in the earnings per share calculations because they were anti-dilutive:
