The Commission undertakes a financial contribution to the work. With the exception of those cases where the Commission's contribution takes the form of a lump sum payment, the Commission reimburses eligible costs incurred by participants as the project progresses.
Payment is made in regular instalments.
Incurred eligible costs Participants are required to identify and declare their eligible costs by the submission of interim and final cost statements based on the actual costs incurred for the execution of the project. Participants must retain supporting documents, which justify these costs, for at least 5 years from the end of each payment to permit auditing by Commission services or other institutions, e.g. the European Court of Auditors. For Accompanying Measures, one calculation method is used for all participants. The overhead may be calculated as a flat rate of the personnel costs and in some cases no overheads may be allowed. For technology take-up measures not all cost categories may be allowable.
