Where the outcome of a construction contract can be estimated reliably, revenue and costs are recognised by reference to the stage of completion of the contract activity at the reporting end date. Variations in contract work, claims and incentive payments are included to the extent that the amount can be measured reliably and its receipt is considered probable.
When it is probable that total contract costs will exceed total contract turnover, the expected loss is recognised as an expense immediately.
Where the outcome of a construction contract cannot be estimated reliably, contract costs are recognised as expenses in the period in which they are incurred and contract revenue is recognised to the extent of contract costs incurred where it is probable that they will be recoverable.
