About these balances

Latest available filing per company, not a reconstructed current portfolio. Matching sequences show the last reported balance with all source rows expandable; grouping alone does not establish account ownership. Do not add unresolved positions together. Filings may omit unchanged positions, and amendments may correct only part of an older disclosure. Jointly reported shares are not necessarily this owner's personal holdings.

F3 · derivative.exercise_date: On June 7, 2018, reporting person was granted an RSU award covering a target of 41,667 ordinary shares (the "Target RSU Number"), subject to satisfaction of predetermined, performance-based vesting criteria that could result in 0% to 200% of the Target RSU Number becoming eligible to vest, subject to certain adjustments. On February 28, 2019, the Company's Board of Directors determined the performance criteria had been satisfied at a level that resulted in 200% of the Target RSU Number becoming eligible for time-based vesting. Pursuant to time-based vesting requirements, the award would vest on March 15, 2021, subject to possible adjustment based on a total stockholder return ("TSR") performance metric for the period February 1, 2018 to January 31, 2021 (the "TSR Period"). As a result of the Company's TSR performance over the TSR Period, the RSUs eligible to vest were reduced by 25% of the Target RSU Number.
