(a)Figures in the table may not recalculate exactly due to rounding. Earnings per share is calculated based on unrounded numbers.

(b)Includes shares related to share-based compensation that vested but were not yet issued.

(c)Due to the antidilutive effect of the net loss from continuing operations for the six months ended June 30, 2020, basic weighted-average common shares outstanding was used to calculate basic and diluted earnings per share. During the three months and six months ended June 30, 2020, there were 2.3 million and 2.4 million, respectively, in shares underlying share-based awards excluded because their inclusion would have been antidilutive. There were no antidilutive shares during the three months and six months ended June 30, 2021.
