(**) Including, at 31 December 2022, measurement at fair value of the assets and liabilities of London Gatwick airport (€1,559 million), Mexican airport operator OMA (€770 million), ASF (€719 million), Cobra IS (€209 million), Lima Expresa (€172 million), Aéroports de Lyon (€131 million) and ANA (€105 million) upon their consolidation.
Impairment of deferred tax assets as a whole amounted to €641 million at 31 December 2022 (€502 million at 31 December 2021), including €601 million outside France (€465 million at 31 December 2021).
Deferred tax assets arising from tax loss carryforwards totalled €703 million at 31 December 2022, with impairment losses recognised in the amount of €403 million. The net balance of deferred tax assets arising from tax loss carryforwards thus comes to €301 million, mainly related to countries in which tax losses can generally be carried forward indefinitely, such as the United Kingdom, the United States and Germany.
Basic earnings per share is the net income for the period after non-controlling interests, divided by the weighted average number of shares outstanding during the period less the weighted average number of treasury shares.
In calculating diluted earnings per share, the weighted average number of existing shares is adjusted for the potentially dilutive effect of all equity instruments issued by the company, in particular Group savings plans and unvested performance shares. Dilution is determined in accordance with the rules laid down by IAS 33. In accordance with this standard, plans of which the stock market price is greater than the average price during the period are excluded from the diluted earnings per share calculation.
In calculating basic and diluted earnings per share, earnings are also adjusted as necessary for changes in income and expenses taken directly to equity resulting from the conversion into shares of all potentially dilutive instruments.
