Earnings Per Share

Earnings per share for the three-month periods ended March 31, 2013 and 2012 were calculated using the weighted average number of shares outstanding for the related period. The following table reconciles the number of shares used in the computations of basic and diluted earnings per share for the three-month periods ended March 31, 2013 and 2012:

	Three Months Ended
	March 31,
	2013		2012
	(In thousands)
Weighted average number of common shares outstanding during the period used to compute basic earnings per share		20,073		19,416
Incremental common shares attributable to exercise of outstanding options and warrants		11,551		3,185
Weighted average number of common shares used to compute diluted earnings per share		31,624		22,601

If the anti-dilutive effects of common stock equivalents were considered, shares included in the diluted earnings per share calculation for the three-month periods ended March 31, 2013 and 2012 would have included an additional 1.3 million and 3.3 million shares, respectively, attributable to the exercise of outstanding options and warrants.
