Schedule of Antidilutive Securities Excluded from Computation of Earnings Per Share

The following table presents the share-based awards that are not considered in the diluted income (loss) per share calculation generally because the exercise price of the awards was greater than the average per share closing price during the three and six months ended June 30, 2022 and 2021. In certain instances, awards may be anti-dilutive even if the average market price exceeds the exercise price when the sum of the assumed proceeds exceeds the difference between the market price and the exercise price.

			Three Months Ended June 30,												Six Months Ended June 30,
			2022						2021						2022						2021
Anti-dilutive stock awards			1.8						1.4						3.0						0.5

Tabular disclosure of securities (including those issuable pursuant to contingent stock agreements) that could potentially dilute basic earnings per share (EPS) in the future that were not included in the computation of diluted EPS because to do so would increase EPS amounts or decrease loss per share amounts for the period presented, by antidilutive securities.
