Where the outcome of construction contracts can be reliably estimated, contract revenue and contract costs are recognised by reference to the stage of completion of the contract activity as at the period end.
Where the outcome of construction contracts cannot be estimated reliably, revenue is recognised to the extent of contract costs incurred that it is probable will be recoverable, and contract costs are recognised as an expense in the period in which they are incurred.
The entity uses the percentage of completion method to determine the amounts to be recognised in the period. The stage of completion is measured by reference to the contract costs incurred up to the end of the reporting period as a percentage of total estimated costs for each contract. Costs incurred for work performed to date do not include costs relating to future activity, such as for materials or prepayments.
