Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

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, 2015		March 31, 2014
Net income available to common stockholders, basic and diluted	$	27,670	26,730
Average outstanding shares - basic	75,206,348		74,437,393
Add: dilutive stock options and awards	38,611		43,425
Average outstanding shares - diluted	75,244,959		74,480,818
Basic earnings per share	$	0.37	0.36
Diluted earnings per share	$	0.37	0.36

There were 55,497 and 0 stock options and restricted stock awards excluded from the diluted average outstanding share calculation for the three months ended March 31, 2015 and 2014, respectively, 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.
