Note 9—Earnings Per Share

The Company’s unvested restricted shares and restricted stock units contain nonforfeitable rights to dividends and, therefore, are considered participating securities for purposes of computing earnings per share pursuant to the two-class method. The computation below of earnings per share excludes the income attributable to the unvested restricted shares and restricted stock units from the numerator and excludes the dilutive impact of those underlying shares from the denominator. Stock options are included in the calculation of diluted earnings per share utilizing the treasury stock method and performance share awards are included in the calculation of diluted earnings per share using the contingently issuable method. Neither is considered to be a participating security as they do not contain non-forfeitable dividend rights.

The following reflects the Income from continuing operations and share data used in the basic and diluted earnings per share computations using the two-class method:

	Three Months Ended						Nine Months Ended
	September 30,						September 30,
(in millions except share amounts)	2013			2012			2013			2012

Numerator for basic and diluted EPS	$	76.2		$	69.3		$	139.4		$	217.9

Denominator (in thousands):
Denominator for basic EPS: weighted-average common shares outstanding	63,567			62,708			63,429			62,347
Effect of dilutive securities:
Performance awards	374			448			374			448

Per share income from continuing operations:
Basic	$	1.20		$	1.11		$	2.19		$	3.50
Diluted	$	1.18		$	1.08		$	2.16		$	3.43

(1) Basic weighted-average common shares outstanding	63,567		62,708		63,429		62,347
Basic weighted-average common shares outstanding, unvested restricted shares expected to vest and restricted share units	63,892		63,067		63,755		62,707
Percent allocated to common shareholders	99.5	%	99.4	%	99.5	%	99.4	%

To calculate earnings per share for Income from discontinued operations and for Net income, the denominator for both basic and diluted earnings per share is the same as used in the above table. Income from discontinued operations and Net income were as follows:

	Three Months Ended					Nine Months Ended
	September 30,					September 30,
(in millions except share amounts)	2013		2012			2013			2012

Income (loss) from discontinued operations attributable to common shareholders for basic and diluted earnings per share	$	—	$	(0.2	)	$	(0.1	)	$	3.2

Net income attributable to common shareholders for basic and diluted earnings per share	$	76.2	$	69.1		$	139.3		$	221.1

Antidilutive stock options excluded from EPS calculation(2)	—		—			—			—

(2) Represents stock options excluded from the calculation of diluted earnings per share as such options had exercise prices in excess of the weighted-average market price of the Company’s common stock during these periods. Amounts in thousands.
