Explanation of Responses:
1. Performance stock units ("PSUs) convert into common stock on a one-for-one basis.
2. The PSUs vested upon the achievement of the applicable stock price hurdle, defined as the closing price per share exceeding $46.25 for any twenty (20) consecutive trading day period during the performance period and the reporting person's continuous employment through December 13, 2025.
3. Represents the number of common stock that have been withheld by the issuer to satisfy its income tax withholding and remittance obligations in connection with the net settlement of the PSUs and does not represent a sale.
4. The remaining PSUs are eligible to vest based on achievement of four pre-established stock price hurdles (each, a "Stock Price Hurdle") during a seven-year performance period beginning on December 13, 2022. Each of the four tranches of PSUs will vest on the later of the date that the applicable Stock Price Hurdle is achieved or the fourth, fifth, sixth and seventh anniversaries of the grant date.
