Earnings (Loss) Per Share

6 Months Ended

Jun. 30, 2021

Diluted weighted average shares is calculated as basic weighted average shares plus the effect, calculated using the treasury stock method, of assuming that restricted share units and performance share units have vested. The following table provides a reconciliation between the Company's basic weighted average number of common shares outstanding to its diluted weighted average number of common shares outstanding:


(In thousands, except per share data)	Three Months Ended June 30				Six Months Ended June 30
	2021		2020		2021		2020
Weighted average number of common shares outstanding, basic	53,965		53,864		53,942		53,836
Dilutive effect of securities:
Restricted Share Units	81		22		78		48
Performance Share Units	2		—		3		2


Weighted average number of common shares outstanding, diluted	54,048		53,886		54,023		53,886
Effect of dilutive shares on earnings (loss) per share	$	(0.01)	$	—	$	—	$	—

The diluted weighted average number of common shares outstanding for the three and six months ended June 30, 2021 excludes approximately 37,000 and 19,000, respectively, of common share equivalents issuable under the Company's stock compensation plans, as compared to approximately 180,000 and 90,000 during the same respective periods of 2020, as their effect would have been antidilutive.

Dilutive common share equivalents are reflected in the earnings (loss) per share calculation while antidilutive common share equivalents are not reflected in the earnings (loss) per share calculation. For the three and six months ended June 30, 2020, all incremental common share equivalents were not included in the computation of diluted earnings (loss) per share because to do so would have been antidilutive.
