During the years ended December 31, 2023 and 2022, 83,753 and 57,206 shares, respectively, were withheld from issuance related to restricted stock units vesting and stock option exercises to cover employee taxes and stock options exercise price. Non-employee directors Restricted Stock Units (“RSUs”) typically vest over the earlier of one year or the next annual meeting of shareholders and Non-Qualified stock options vest over three years and have a six-year exercise period. Employee RSUs typically vest annually over three or four years and employee Non-Qualified stock options typically vest quarterly over four years and have a six-year exercise period. Performance Stock Units (“PSUs”) typically cliff vest at the end of the performance period and the performance metric is cumulative revenue growth over the three-year period ending December 31, 2025 with a cumulative revenue threshold, target, and maximum performance measure. The table above includes performance shares granted in 2023 of 30,000 shares at the target performance level (the threshold level would be 50% and the maximum level would be 150% of the target level).
