(16) Work in progress assets
Work in progress assets concern the right to consideration in respect of work on projects carried out and transferred to the client. In practical terms, the item is made up of the revenue (see also accounting policy 6) in proportion to the progress in fulfilling the performance obligation less invoiced instalments. Total expected project losses, if any, are directly recognised as expenses in the relevant period and are accounted for on the balance sheet in provisions (see also accounting policy 24d). Work in progress assets are measured taking account of expected credit losses in a way similar to the method used for trade and other receivables (see accounting policy 17).
