Within its mandate to protect the financial interests of the Union, the Office shall cooperate, as appropriate, with Eurojust and with the European Police Office (Europol). Where necessary in order to facilitate that cooperation, the Office shall agree with Eurojust and Europol on administrative arrangements. Such working arrangements may concern exchange of operational, strategic or technical information, including personal data and classified information and, on request, progress reports.

Where this may support and strengthen coordination and cooperation between national investigating and prosecuting authorities, or where the Office has forwarded to the competent authorities of the Member States information giving grounds for suspecting the existence of fraud, corruption or any other illegal activity affecting the financial interests of the Union in the form of serious crime, it shall transmit relevant information to Eurojust, within the mandate of Eurojust.

The competent authorities of the Member States concerned shall be informed, in a timely manner, by the Office in cases where information provided by them is transmitted by the Office to Eurojust or Europol.
