Notes:

1The prior year comparatives have been re-presented to reflect that Vodafone Egypt is no longer held for sale. See note 7 "Discontinued operations and assets and liabilities held for sale". The impact of the re-presentation is to increase Trade and other receivables within non-current assets and within current assets by €15 million and €313 million, respectively.

2Items are measured at fair value and the valuation basis is level 2 classification, which comprises items where fair value is determined from inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly.
