Annual Report 2019

148 CHINA MERCHANTS PORT HOLDINGS COMPANY LIMITED Notes to the Consolidated Financial Statements For the year ended 31 December 2019 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) 2.19 Employee benefits (continued) (iv) Short-term employee benefits Short-term employee benefits are recognised at the undiscounted amount of the benefits expected to be paid as and when employees rendered the services. All short-term employee benefits are recognised as an expense unless another HKFRS requires or permits the inclusion of the benefit in the cost of an asset. A liability is recognised for benefits accruing to employees (such as wages and salaries, annual leave and sick leave) after deducting any amount already paid. 2.20 Provisions Provisions are recognised when the Group has a present legal or constructive obligation as a result of past events; it is probable that an outflow of resources will be required to settle the obligation; and the amount has been reliably estimated. Restructuring provisions comprise provision for assets relocation and employee termination payments. Provisions are not recognised for future operating losses. Where there are a number of similar obligations, the likelihood that an outflow will be required in settlement is determined by considering the class of obligations as a whole. A provision is recognised even if the likelihood of an outflow with respect to any one item included in the same class of obligations may be small. Provisions are measured at the present value of the best estimate of the consideration required to settle the present obligation at the end of the reporting period using a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the obligation. The increase in the provision due to passage of time is recognised as interest expense. 2.21 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 or enhances an asset that the customer controls as the asset is created or enhanced; 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.
