Pay Versus Performance Table

The following table sets contains information about the relationship between CAP, as computed in accordance with SEC rules, to our principal executive officers (“PEO”) and non-PEO NEOs as a group, and our financial performance for the five years 2021 – 2025. The cumulative Total Stockholder Return depicts a hypothetical $100 investment in our common stock on December 31, 2020, and shows the value of that investment over time for each calendar year. A hypothetical $100 investment in the Nasdaq Biotechnology Index (“NBI”) using the same methodology is shown for comparison. In addition, the average non-PEO NEO incumbents differ year to year and may comprise different roles with different individual and market-based considerations impacting compensation decisions. Comparing the summary compensation table total average and CAP average for the non-PEO NEOs year over year does not accurately depict changes in these values for the same individuals.

Measurement date equity fair values are calculated with assumptions derived on a basis consistent with, and are not materially different from, those used for grant date fair value purposes. Restricted share units are valued based on the last sale price of our ordinary shares on the Nasdaq Global Select Market on the relevant measurement date. Performance share units are valued by applying the probable or actual outcome based on performance through the measurement date, multiplied by the last sale price of our ordinary shares on the Nasdaq Global Select Market on the relevant measurement date. Options are valued using a Hull & White option pricing model with assumptions established as at the relevant measurement date.

Tabular List, Table

Tabular List of Company Performance Measures

As described in our CD&A, we believe that compensation should pay for performance, align interest with our shareholders, use at-risk compensation to incentivize executives, and attract and retain talented executives. We seek to align compensation opportunities for our NEOs with our strategic priorities, which largely reflect non-financial measures. Total Shareholder Return is the only financial measure (per the definition in Item 402(v)(2) of Regulation S-K) currently used in our executive compensation program to assess performance in respect of the 2021 PSU awards on a relative basis. As a result of Total Shareholder Return already being included in the Pay Versus Performance table, no company-selected measure is identified or reported.
