  4. On March 28, 2017, reporting person was granted an RSU award covering a target of 39,437 ordinary shares (the "Target RSU Number"), subject to satisfaction of predetermined, performance-based vesting criteria that could result in 0% - 150% of the Target RSU Number becoming eligible to vest, subject to certain adjustments. On February 26, 2018, the Company's Board of Directors determined the performance criteria for the RSUs had been satisfied at a level that resulted in 100% of the Target RSU Number becoming eligible for time-based vesting. Pursuant to time-based vesting requirements, 100% of the award would vest on March 15, 2020, subject to possible adjustment based on a total stockholder return ("TSR") performance metric covering the period of February 1, 2017 to January 31, 2020 (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%. A total of 29,578 ordinary shares were delivered to reporting person.
