On February 23, 2022, the reporting person reported the acquisition of the performance-based restricted stock unit award. One-third of the shares vested on February 23, 2022, one-third of the shares vested on February 23, 2023, and the remaining one-third vested on February 23, 2024, subject to adjustment based on the Company's relative total shareholder return ("TSR") over the measurement period starting on January 1, 2021, through to December 31, 2023. As a result of the Company's relative TSR, the third tranche was adjusted downward by 15%. As such, the reporting person received 245 less shares than the amount initially reported.
