 level. Consequently, 2/3rds of the unvested PSUs represent 125% of the target number of PSUs eligible to be earned and have been moved to the "Shares or Units of Stock That Have Not Vested" column.

(5) For the 2023 PSUs, the number of PSUs shown that have not vested reflects the fact that one of the three performance period achievements was attained as of December 31, 2024, at the maximum performance level. Consequently, 1/3rd of the unvested PSUs represent 125% of the target number of PSUs eligible to be earned and have been moved to the "Shares or Units of Stock That Have Not Vested" column.

(6) For the remaining unvested PSUs eligible to be earned, as our previous year’s performance for PSUs has exceeded the target level, the number of PSUs shown has been determined based on the next higher performance measure that exceeded the previous year’s performance, which is the maximum performance level for all PSUs. Consequently, the remaining 1/3rd of the unvested 2022 PSUs, 2/3rds of the unvested 2023 PSUs, and all of the unvested 2024 PSUs represent 125% of the target number of PSUs eligible to be earned and remain in the “Equity Incentive Plan Awards: Number of Unearned Shares, Units or Other Rights That Have Not Vested" column.
