[1] Represents PSUs awarded in February 2023. The PSU awards provide for vesting in two equal annual installments on each of December 31, 2024 and December 31, 2025, based on the extent to which the Company achieves certain financial metrics relative to targets established by the Company’s Compensation Committee of its Board of Directors. The estimated grant-date fair value per PSU was measured based on the quoted price of our common stock at the date of grant, calculated upon the establishment of performance targets, and will be amortized on a straight-line basis over the requisite service period. Based upon actual attainment relative to the target financial metrics, employees have the ability to receive up to 200% of the target number originally granted, or to be issued none at all. Probable outcome for performance-based awards is updated based upon changes in actual and forecasted operating results or expected achievement of performance goals, as applicable, and the impact of modifications, if any.

[2] MSUs shall vest three years from grant date, generally with 25% vesting if the weighted-average stock price over a 30-day trading period during the vesting period is equal to or greater than $35.00 but less than $45.00, 50% vesting if equal to or greater than $45.00 but less than $55.00, and 100% vesting if equal to or greater than $55.00, subject to continuous employment with, or performance of services for, the Company. A Monte-Carlo simulation model, which simulated the present value of the potential outcomes of future stock prices was used to calculate the grant-date fair value of our MSU awards. The estimated grant-date fair value of these awards is amortized on a straight-line basis over the requisite service period and is not adjusted based on the actual number of awards that ultimately vest.
