Retirements and disposals (paras. 112-117)
112 An intangible asset shall be derecognised:
(a) on disposal; or
(b) when no future economic benefits are expected from its use or disposal.
113 The gain or loss arising from the derecognition of an intangible asset shall be determined as the difference between the net disposal proceeds, if any, and the carrying amount of the asset. It shall be recognised in profit or loss when the asset is derecognised (unless IFRS 16 requires otherwise on a sale and leaseback.) Gains shall not be classified as revenue.
114 The disposal of an intangible asset may occur in a variety of ways (eg by sale, by entering into a finance lease, or by donation). The date of disposal of an intangible asset is the date that the recipient obtains control of that asset in accordance with the requirements for determining when a performance obligation is satisfied in IFRS 15. IFRS 16 applies to disposal by a sale and leaseback.
