Earnings Per Share

(6) Earnings Per Share

Earnings per share for the three-month periods ended March 31, 2020 and 2019 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, 2020 and 2019:

	Three Months Ended
	March 31,
	2020		2019
	(In thousands)
Weighted average number of common shares outstanding during the period used to compute basic earnings per share		22,539		22,242
		$
Incremental common shares attributable to exercise of outstanding options and warrants		1,340		2,017
		$
Weighted average number of common shares used to compute diluted earnings per share		23,879		24,259

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, 2020 and 2019 would have included an additional 12.9 million and 10.5 million shares, respectively, attributable to the exercise of outstanding options and warrants.
