"– Under the previous policy, revenue allocated to obligations was restricted to the amount receivable without the delivery of additional goods or services; this restriction no longer applies under the current policy. The primary impact is that revenue allocated to equipment typically increases and revenue subsequently recognised for service delivery during the contract period typically decreases when the Group sells subsidised devices, such as handsets, together with airtime service agreements. The recognition of additional up-front unbilled equipment revenue is the primary driver for the increase in the contract asset value recorded under IFRS 15 (see page 123 and in note 14 “Trade and other receivables”)."
