All performance units are subject to time based vesting and require service through January 1, 2024 or an earlier change in control. Once vested, performance units convert into shares of common stock on a 1-for-1 basis and one-third of the resulting shares have no sales restrictions and are sellable on January 1, 2024, one-third of the shares have sales restrictions until January 1, 2025 and one-third have sales restrictions until January 1, 2026. On April 23, 2019, the first price target had been met and approved by the Compensation Committee, which resulted in 9,600 units being credited, subject to time based vesting above. The reported sales were to cover taxes upon the vesting of restricted stock units, as required by the Company's equity incentive plans. By: Saria Tseng For: Deming Xiao 2019-07-03
