[1] Calculated using the “Treasury Stock” method as if dilutive securities were exercised and the funds were used to purchase common shares at the average market price during the period.

[2] Anti-dilutive securities were excluded from the computation of diluted net income per share for the three months ended September 30, 2024, and September 30, 2023, because the exercise price was greater than the average fair market price of the common shares or because the assumed proceeds from the award’s exercise or vesting was greater than the average fair market price of the common shares.
