Earnings Per Share

6 Months Ended

Jun. 30, 2015

Basic earnings per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period presented. Diluted earnings per share is computed by including the net increase in shares as if dilutive outstanding stock options were exercised and restricted stock awards were vested, using the treasury stock method.

Basic and diluted earnings per share has been computed based on the following:



	Three Months ended			Six Months ended
(Dollars in thousands, except per share data)	June 30, 2015		June 30, 2014	June 30, 2015	June 30, 2014
Net income available to common stockholders, basic and diluted	$	29,335	28,677	57,005	55,407
Average outstanding shares - basic	75,530,591		74,467,576	75,369,366	74,452,568
Add: dilutive stock options and awards	35,064		32,084	38,255	38,891
Average outstanding shares - diluted	75,565,655		74,499,660	75,407,621	74,491,459
Basic earnings per share	$	0.39	0.38	0.76	0.74
Diluted earnings per share	$	0.39	0.38	0.76	0.74

There were no stock options or restricted stock awards excluded from the diluted average outstanding share calculation for the six months ended June 30, 2015 and 2014, because to do so would have been anti-dilutive for those periods. Anti-dilution occurs when the exercise price of a stock option or the unrecognized compensation cost per share of a restricted stock award exceeds the market price of the Company’s stock.
