Earnings Per Share

6 Months Ended

Jun. 30, 2016

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, 2016		June 30, 2015	June 30, 2016	June 30, 2015
Net income available to common stockholders, basic and diluted	$	30,451	29,335	59,133	57,005
Average outstanding shares - basic	76,170,734		75,530,591	76,148,493	75,369,366
Add: dilutive stock options and awards	34,335		35,064	43,162	38,255
Average outstanding shares - diluted	76,205,069		75,565,655	76,191,655	75,407,621
Basic earnings per share	$	0.40	0.39	0.78	0.76
Diluted earnings per share	$	0.40	0.39	0.78	0.76

There were no stock options or restricted stock awards excluded from the diluted average outstanding share calculation for the six months ended June 30, 2016 and 2015, 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.
