Earnings Per Share

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:

To calculate earnings per share for Loss 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. Loss from discontinued operations and Net income were as follows:

	Three Months Ended
	March 31,
(in millions except share amounts)	2013			2012
Loss from discontinued operations attributable to common shareholders for basic and diluted earnings per share	$	(0.1	)	$	—
Net income attributable to common shareholders for basic and diluted earnings per share	$	54.9		$	59.6
Antidilutive stock options excluded from EPS calculation(2)	—			476

(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.
