(6) Earnings Per Share

Earnings per share for the three-month periods ended March 31, 2019 and 2018 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, 2019 and 2018:

	Three Months Ended
	March 31,
	2019		2018
	(In thousands)
Weighted average number of common shares outstanding during the period used to compute basic earnings per share		22,242		21,576
Incremental common shares attributable to exercise of outstanding options and warrants		2,017		4,088
Weighted average number of common shares used to compute diluted earnings per share		24,259		25,664

If the anti-dilutive effects of common stock equivalents were considered, shares included in the diluted earnings per share calculation for the three-months ended March 31, 2019 and 2018 would have included an additional 10.5 million and 9.3 million shares, respectively, attributable to the exercise of outstanding options and warrants.
