Worked-up income from ongoing contracts is recognized over time. The degree of recognition is calculated on the basis of the project costs incurred at the end of the period in relation to the project costs corresponding to the project income for the whole project.

Contract assignments are recognized in gross on the balance sheet project for project, either as Worked-up income not invoiced in current assets or as Invoiced income not worked-up in current liabilities. Projects that have higher worked-up income than the amounts invoiced are recognized as assets, while projects that have invoiced more than the income worked-up are recognized as liabilities.
