        <footnote id="F1">Performance share units granted under the Issuer's Long-Term Incentive Plan for the three-year performance period shown in Column 1, based on the Compensation Committee's certified results for that period. Each performance share unit represents a contingent right to receive one ordinary share of the Issuer upon vesting, and has no expiration date. The performance share units do not accrue dividends. Following certification, the award vests 50% on May 1 of the year immediately after the performance period ends and 50% on May 1 of the following year.</footnote>
        <footnote id="F2">Each restricted share unit represents a contingent right to receive one ordinary share of the Issuer upon vesting. The restricted share units vest in three substantially equal annual installments on July 14 of each of 2026, 2027 and 2028, and have no expiration date.</footnote>
