The following is a reconciliation of the earnings and share data used in the basic and diluted earnings per share computations for the three and nine months ended September 30, 2012 and 2011 (in millions, except share amounts):

	Three Months Ended September 30,					Nine Months Ended September 30,
	2012		2011			2012		2011
Net earnings	$	125.4	$	19.2		$	794.9	$	105.6
Effect of dilutive securities		—		(1.3	)		0.2		(1.1	)
Income available to common stockholders for diluted earnings per share	$	125.4	$	17.9		$	795.1	$	104.5
Weighted average common shares outstanding applicable to basic earnings per share		16,931,811		8,811,807			14,943,160		8,881,601
Effect of dilutive securities		—		10,749			19,855		9,858
Adjusted weighted average common shares outstanding applicable to diluted earnings per share		16,931,811		8,822,556			14,963,015		8,891,459

Contingently issuable shares of 52,627 and 37,228 were potentially available during the first nine months of 2012 and 2011, respectively, but were not included in the computations of diluted earnings per share because the impact was anti-dilutive to the earnings per share calculation.
