Annual Report 2019

NOTESTOTHE CONSOLIDATED FINANCIAL STATEMENTS For the year ended 31 December 2019 61 The United Laboratories International Holdings Limited Annual Report 2019 3. SIGNIFICANT ACCOUNTING POLICIES (Continued) Revenue from contracts with customers The Group recognises revenue when (or as) a performance obligation is satisfied, i.e. when “control” of the goods or services underlying the particular performance obligation is transferred to the customer. A performance obligation represents a good or service (or a bundle of goods or services) that is distinct or a series of distinct goods or services that are substantially the same. Control is transferred over time and revenue is recognised over time by reference to the progress towards complete satisfaction of the relevant performance obligation if one of the following criteria is met: • the customer simultaneously receives and consumes the benefits provided by the Group’s performance as the Group performs; • the Group’s performance creates and enhances an asset that the customer controls as the Group performs; or • the Group’s performance does not create an asset with an alternative use to the Group and the Group has an enforceable right to payment for performance completed to date. Otherwise, revenue is recognised at a point in time when the customer obtains control of the distinct good or service. A contract liability represents the Group’s obligation to transfer goods or services to a customer for which the Group has received consideration (or an amount of consideration is due) from the customer. Leases Definition of a lease (upon application of HKFRS 16 in accordance with transitions in Note 2) A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. For contracts entered into or modified or arising from business combinations on or after the date of initial application, the Group assesses whether a contract is or contains a lease based on the definition under HKFRS 16 at inception, modification date or acquisition date, as appropriate. Such contract will not be reassessed unless the terms and conditions of the contract are subsequently changed.
