EARNINGS PER SHARE

We compute basic earnings per common share by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common and potential common shares include additional shares in the weighted average share calculations associated with the incremental effect of dilutive employee stock options, restricted stock awards and contingently issuable shares, as determined using the treasury stock method. The

following table summarizes the calculation of weighted average common shares outstanding used in the computation of diluted earnings per share (in thousands):



	Three Months Ended		Nine Months Ended
	September 30,		September 30,
	2011	2010	2011	2010
	(Unaudited)		(Unaudited)
Weighted average basic common shares outstanding	46,606	44,736	45,930	44,741
Effect of dilutive securities:
Stock options	12	55	20	58
Contingent shares	80	38	69	37
Restricted stock and other	249	591	266	564
Senior exchangeable notes	1,083	2,030	1,144	1,735
Warrants	—	1,505	1,205	788
Weighted average diluted common and potential common shares outstanding	48,030	48,955	48,634	47,923

Included in the table above are 0 and 1,505,000 shares which were added to the share count for the three months ended September 30, 2011 and 2010, respectively, and 1,205,000 and 788,000 shares which were added to the share count for the nine months ended September 30, 2011 and 2010, respectively, because the average share price exceeded the strike price of the warrants. These shares were included in calculating the impact to our dilutive earnings per share for the three and nine months ended September 30, 2011 and 2010.
