[1] Inclusive of approximately 378,000 MSUs awarded to our CEO during July 2022. 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. These MSUs shall vest on July 1, 2025, with 25% vesting if our stock price is equal to or greater than $35.00 but less than $45.00, 50% if our stock price is equal to or greater than $45.00 but less than $55.00 and 100% if our stock price is equal to or greater than $55.00, subject to the CEO’s continuous employment with, or performance of services for, the Company. The estimated grant-date fair value of this award will be amortized on a straight-line basis over the requisite service period through July 1, 2026. All other MSU grants during the year, to various employees, contained similar vesting and performance conditions.

[2] MSU cancellations primarily reflect performance targets not being attained by the end of the performance period.
