(6) Earnings Per Share

Earnings per share for the three-month periods ended March 31, 2018 and 2017 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, 2018 and 2017:

		Three Months Ended
		March 31,
		2018				2017
		(In thousands)
Weighted average number of common shares outstanding during the period used to compute basic earnings per share			21,576				23,517
Incremental common shares attributable to exercise of outstanding options and warrants			4,088				4,706
Weighted average number of common shares used to compute diluted earnings per share			25,664				28,223

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, 2018 and 2017 would have included an additional 9.3 million and 6.6 million shares, respectively, attributable to the exercise of outstanding options and warrants.
