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 March 31
		2026		2025
Weighted average number of common shares outstanding, basic		51,491		51,188
Dilutive effect of securities:
Restricted Share Units		217		188
Performance Share Units		103		69


Weighted average number of common shares outstanding, diluted		51,811		51,445
Effect of dilutive shares on earnings (loss) per share		$	—	$	—

There were no antidilutive common share equivalents for the three months ended March 31, 2026 and 2025.

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 months ended March 31, 2025, all incremental common share equivalents were not included in the computation of diluted loss per share because to do so would have been antidilutive.
