[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.
[2] | pproximately 85,000 outstanding MSUs provide for vesting based upon the Company’s total shareholder return, or TSR, performance over the period commencing January 1, 2020 through December 31, 2022 relative to the TSR performance of The Nasdaq Composite Total Return Index. Based upon actual attainment relative to the target performance metric, the grantees have the ability to receive up to 200% of the target number of MSUs originally granted, or to receive none at all.
