Earnings Per Share [Abstract]

Earnings Per Common Share

Earnings Per Common Share

Basic earnings per common share for the Corporation is computed by dividing net income by the weighted average number of common shares outstanding during the period. Basic earnings per common share excludes any dilutive effect of common stock equivalents.

Diluted earnings per common share for the Corporation is computed by dividing net income by the sum of the weighted average number of common shares outstanding and the dilutive effect of common stock equivalents using the treasury stock method. Average shares of common stock for diluted net income per common share include shares to be issued upon the exercise of stock options granted under the Corporation’s share-based compensation plans, restricted stock units that may be converted to stock, stock to be issued under the deferred stock compensation plan for non-employee directors and stock to be issued under the stock purchase plan for non-employee advisory directors. For any period in which a net loss is recorded, the assumed exercise of stock options, restricted stock units that may be converted to stock and stock to be issued under the deferred stock compensation plan and the stock purchase plan would have an anti-dilutive impact on the net loss per common share and thus are excluded in the diluted earnings per common share calculation.

The following summarizes the numerator and denominator of the basic and diluted earnings per common share computations:

	Three Months Ended March 31,
	2013		2012
	(In thousands, except per share data)
Numerator for both basic and diluted earnings per common share, net income	$	13,234	$	12,374
Denominator for basic earnings per common share, weighted average common shares outstanding	27,519		27,478
Weighted average common stock equivalents	122		61
Denominator for diluted earnings per common share	27,641		27,539
Basic earnings per common share	$	0.48	$	0.45
Diluted earnings per common share	0.48		0.45

The average number of exercisable employee stock option awards outstanding that were “out-of-the-money,” whereby the option exercise price per share exceeded the market price per share and, therefore, were not included in the computation of diluted earnings per common share because they would have been anti-dilutive totaled 457,689 and 604,843 for the three months ended March 31, 2013 and 2012, respectively.
