Earnings Per Share of Common Stock

3. Earnings Per Share of Common Stock

The following is a reconciliation of the income and share data used in the basic and diluted earnings per share computations for the three and six months ended June 30, 2011 and 2010 (in millions, except share amounts):

	Three months ended June 30,						Six months ended June 30,
	2011			2010			2011			2010
Net earnings	$	15.1		$	66.3		$	86.4		$	124.4
Effect of dilutive securities		(0.1	)		(0.1	)		(0.2	)		(0.5	)
Income available to common stockholders for diluted earnings per share	$	15.0		$	66.2		$	86.2		$	123.9
Weighted average shares outstanding applicable to basic earnings per share		8,916,620			9,124,187			8,921,950			9,164,443
Effect of dilutive securities		5,352			9,788			5,168			9,489
Adjusted weighted average shares outstanding applicable to diluted earnings per share		8,921,972			9,133,975			8,927,118			9,173,932

Contingently issuable shares of 42,429 and 40,756 were potentially available during the first six months of 2011 and 2010, 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.

Earnings per share by quarter may not equal the amount for the full year due to the timing of treasury stock purchases and rounding.
