Sep. 30, 2020

Earnings (Loss) per Ordinary ShareBasic earnings (loss) per ordinary share is computed by dividing net earnings (loss) by the weighted average number of ordinary shares outstanding during the period. Diluted earnings (loss) per ordinary share is computed by dividing net earnings (loss) by the weighted average number of ordinary shares outstanding during the period increased by the number of additional shares that would have been outstanding related to potentially dilutive securities or instruments, if the impact is dilutive.

Basic and diluted earnings (loss) per ordinary share are calculated as follows:

Additional stock awards and restricted stock awards were outstanding during the three and nine months ended September 30, 2020 and 2019, but were not included in the computation of diluted earnings per ordinary share for each respective period because the effect would be anti-dilutive. Excluded shares at September 30, 2020 include certain share-based compensation awards whose performance conditions had not been fully met. Such excluded shares and anti-dilutive awards represented 8.8 million shares and 9.8 million shares for the three and nine months ended September 30, 2020, respectively, and 10.0 million shares and 9.9 million shares for the three and nine months ended September 30, 2019, respectively.
