27. Trade and other payables

Trade payables are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Accounts payable are classified as current liabilities if payment is due within one year or less. If not, they are presented as non-current liabilities.

Trade and other payables are recognised initially at fair value and subsequently measured at amortised cost using the effective interest method. A contract liability is recognised when the Group has an obligation to transfer goods or services to a customer for which the entity has received consideration (or the amount is due) from the customer.
