On February 4, 2020, the reporting person was granted a target of 13,233 shares of restricted stock units, with the right to earn up to 300% of the target shares, subject to satisfaction of pre-determined, performance-based vesting criteria. On February 3, 2022, the Company's Compensation Committee of the Board of Directors determined and approved the achievement of the performance criteria for the restricted stock units, which resulted in 26,466 additional shares being earned by the reporting person. Of the restricted stock units that were awarded, 19,851 will vest immediately and 19,848 will vest quarterly in the next two years.
Ending balance was reduced by 646 to reflect the cancelled unvested RSU awards.
