On February 2, 2021, the reporting person was granted a target number of 8,685 performance units that can be earned subject to the achievement of two performance goals related to certain environmental objectives, with a performance period through December 31, 2023. The performance units vest upon achievement of the goals, but no earlier than December 31, 2022. Once vested, the performance units have a post-vesting sales restriction period of one year. On May 2, 2023, the Compensation Committee of the Board of Directors determined that the environmental goals had been satisfied, which resulted in 8,685 units being credited with the vesting terms described above.
The reported sales were to cover taxes upon the vesting of restricted stock units, as required by the Company's equity incentive plan.
