(2) Estimated solely for the purpose of calculating the amount of the registration fee pursuant to Rule 457 (c) and (h) under the Securities Act. The offering price per share and aggregate offering price are based upon $252.15, which is the average of the high and low trading prices of the Ordinary Shares as reported on the NASDAQ Global Select Market on May 20, 2026. (3) The Registrant does not have any fee offsets.</ffd:OfferingNote>
