Anti-dilutive stock-based awards of 1.0 million and 1.1 million shares were outstanding at the three-month periods ended June 30, 2024 and 2023, respectively, which were excluded in the computation of the dilutive effect of stock-based awards for the three-month periods then ended. Anti-dilutive stock-based awards of 0.7 million shares were outstanding at each the six-month periods ended June 30, 2024 and 2023, which were excluded in the computation of the dilutive effect of stock-based awards for the six-month periods 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.
