20. Deferred revenue

Deferred revenue mainly relates to aseptic carton filling lines deployed under lease and sale contracts that qualify to be accounted for as operating leases (see notes 5.5.2, 6, 12 and 18 for further details). Advance payments received under such contracts vary between contracts and customers but are recognized as a deferred revenue liability in the statement of financial position at the deployment date and released to profit or loss to achieve recognition of revenue on a straight-line basis, generally over ten years for sale contracts, and over six years for lease contracts and sale and lease arrangements. Advance payments received before the filling line deployment date are initially presented as part of “Trade and other payables” and reclassified to this balance sheet position at the deployment date (see note 18).

The table below provides an overview of the deferred revenue liability.
