Article 18

If the currency of the requested Member State is different from the currency of the applicant Member State, the applicant authority shall express the amount of the claim to be recovered in both currencies.

The exchange rate to be used for the purposes of the recovery assistance shall be the exchange rate published by the European Central Bank on the date before the date the request is sent. Where there is no such rate available on that date, the exchange rate used shall be the latest exchange rate published by the European Central Bank before the date the request is sent.
