Explanation of Responses:

1. Each restricted stock unit represents a contingent right to receive one ordinary share.

2. These ordinary shares were acquired by the reporting person as a result of the vesting of performance-vesting restricted stock unit awards granted to the reporting person on February 20, 2020 with a three-year performance period that ended on December 31, 2022 (the "2020 PRSUs"). The vesting of this portion of the 2020 PRSUs was triggered by the determination of achievement of certain pre-specified performance goals and application of a total shareholder return modifier and represents the final vesting event under the 2020 PRSUs.

3. Shares subject to the restricted stock unit award vest in four equal annual installments, commencing on 2/18/2023.

4. Shares subject to the restricted stock unit award vest in four equal annual installments, commencing on 2/20/2021.

5. This award is fully vested in accordance with its terms.
