EARNINGS PER SHARE

12 Months Ended

Dec. 31, 2019

Basic earnings per share is computed by dividing net earnings attributable to U.S. Concrete by the weighted average number of common shares outstanding during the period. Diluted earnings attributable to U.S. Concrete per share is computed by dividing net earnings by the weighted average number of common shares outstanding during the period after giving effect to all potentially dilutive securities outstanding during the period.

The following is a reconciliation of the components of the basic and diluted earnings per share calculations:



(in millions)	2019		2018		2017
Numerator for basic and diluted earnings per share:
Income from continuing operations attributable to U.S. Concrete	$	14.9	$	30.0	$	26.1
Loss from discontinued operations, net of taxes	—		—		(0.6		)
Net income attributable to U.S. Concrete	$	14.9	$	30.0	$	25.5

Denominator for diluted earnings per share:
Basic weighted average common shares outstanding	16.4		16.5		15.9
Restricted stock awards and RSUs	—		—		0.1
Warrants	—		—		0.6
Diluted weighted average common shares outstanding	16.4		16.5		16.6

Potentially dilutive shares totaling 0.3 million in 2019, 0.2 million in 2018, and 0.1 million in 2017 were excluded from the diluted earnings per share calculations. They related to unvested restricted stock awards and RSUs, and were excluded because of their anti-dilutive effect or their associated performance targets had not been met.
