The control of the Action's expenditure is performed by two officially elected Financial Rapporteurs.

At the end of every grant period, they receive, via the MC Chair, the relevant Yearly Financial Report produced by the Grant Holder. They certify:

• that the overall expenses were necessary for the scientific progress of the Action
• that the Grant Holder managed the funds in line with the MC decisions

The Financial Rapporteurs inform the COST Office of the result of their evaluation (via the MC Chair and the Grant Holder) by means of a signed written statement. If inconsistencies are evident on the submitted Yearly Financial Report, it is the duty of the financial rapporteurs to report their concerns directly to the COST Office. The confidentiality of their disclosure is assured.
