Earnings Per Share

3 Months Ended

Mar. 31, 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
(Dollars in thousands, except per share data)	March 31, 2016		March 31, 2015
Net income available to common stockholders, basic and diluted	$	28,682	27,670
Average outstanding shares - basic	76,126,251		75,206,348
Add: dilutive stock options and awards	47,166		38,611
Average outstanding shares - diluted	76,173,417		75,244,959
Basic earnings per share	$	0.38	0.37
Diluted earnings per share	$	0.38	0.37

There were no stock options or restricted stock awards excluded from the diluted average outstanding share calculation for the three months ended March 31, 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.
