[1] Includes incremental PSUs issued over target.
[2] The income tax shortfall upon vesting of PSUs and DSUs was zero and $2 million in the three and six months ended June 30, 2026, respectively.
[3] The grant date fair value of PSUs is determined based on the Monte Carlo simulation model for the market-based total shareholder return component and the closing market price of the Company’s stock on the grant date for performance-based components. The Monte Carlo simulation model incorporates the probability of achieving the total shareholder return market condition. Compensation expense is recognized using the grant date fair values regardless of whether the market condition is achieved, as long as the requisite service has been provided.
