Accounting policy

The basic earnings per share are obtained by dividing profit for the year by the weighted average number of ordinary shares outstanding during the reporting period. The weighted average number of ordinary shares excludes the treasury shares held by the Group over the reporting period.

The diluted earnings per share are obtained by dividing profit for the year by the weighted average number of ordinary shares, increased by the number of potentially diluting shares attached to the issuance of share options.

The number of potentially diluting shares is calculated for the weighted average number of share options outstanding during the reporting period as the difference between the average market price of ordinary shares during the reporting period and the exercise price of the share option. Share options have a dilutive effect only when the average market price is above the exercise price (share options are “in the money”).

For the purpose of calculating diluted earnings per share, there were no adjusting elements to net income of the year (Solvay share).

Basic and diluted amounts per share for discontinued operations are presented in the consolidated income statement.

The average closing price during 2017 was €118.56 per share (2016: €92.41 per share). Based on this average closing price all share options were in the money, and therefore dilutive, for the presented period (see note F35 Share-based payments).
