NOTE 26 – EARNINGS PER SHARE AND DIVIDEND PER SHARE
When calculating diluted earnings per share for 2018 and 2017, RSUs have been omitted as they are out-of-the-money and thus anti-dilutive, but the RSUs may potentially dilute earnings per share in the future. Please refer to note 3 for information on the RSU share options.
Question:
What was the change in the Weighted average number of shares outstanding incl. dilutive effect of share options from 2018 to 2019?
