It may not be possible to recalculate earnings per share (EPS) attributable to common shareowners by adjusting EPS from continuing operations by EPS from discontinued operations as each amount is calculated independently.

The computation of diluted EPS excludes the effect of the potential exercise of stock awards, including stock appreciation rights and stock options, when the average market price of the common stock is lower than the exercise price of the related stock awards during the period because the effect would be anti-dilutive. In addition, the computation of diluted EPS excludes the effect of the potential exercise of stock awards when the awards’ assumed proceeds exceed the average market price of the common shares during the period. For 2020, 2019 and 2018, there were 32.5 million, 8.3 million and 5.1 million anti-dilutive stock awards excluded from the computation, respectively. All outstanding stock awards are excluded in the computation of diluted EPS in 2020 because their effect was antidilutive due to the loss from continuing operations.
