Anti-dilutive stock-based awards of 0.9 million, 2.0 million and 1.3 million shares were outstanding at December 31, 2023, 2022 and 2021, respectively, but were excluded in the computation of the dilutive effect of stock‑based awards for the year then ended. These stock-based awards were excluded from the computation because the exercise prices on these stock-based awards were greater than the average market price of our common shares during the respective period, and therefore, would be anti-dilutive to earnings per share under the treasury stock method.
