| Revenue is recognised in relation to the value of work carried out which is based on the project as a whole. Judgements are made on the timing of revenue recognition based on the percentage completion of the work, and the expected outcome of the contract.
The degree of completion of contracts is estimated by reviewing the costs incurred to date against the total expected costs of the project.
Construction contracts:
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.
The "percentage of completion method" is used to determine the appropriate amount to recognise in a given period. The stage of completion is measured by the proportion of contract costs incurred for work performed to date compared to the estimated total contract costs. Costs incurred in the year in connection with future activity on a contract are excluded from contract costs in determining the stage of completion. These costs are presented as stocks, prepayments or other assets depending on their nature, and provided it is probable they will be recovered. |
