Weighted-average common shares outstanding (in millions)
Weighted-average common shares outstanding - basic		58.7		60.6
Effect of dilutive securities - stock options		—		—
Effect of other share-based awards		0.3		0.4
Weighted-average common shares outstanding - diluted		59.0		61.0
Net earnings per share - basic	$	0.03	$	0.88

There were 0.6 million share-based awards excluded from the calculation of net earnings per share – diluted for both the three months ended March 31, 2020 and 2019, because their impact was anti-dilutive.
