Without prejudice to specific provisions arising from the application of sector-specific regulations, conversion by the responsible authorising officer shall be made using the daily euro exchange rate published in the C series of the Official Journal of the European Union.

Where conversion between the euro and another currency is to be made by the contractors or beneficiaries, the specific arrangements for conversion contained in procurement contracts, grant agreements or financing agreements shall apply.

In order to avoid that currency conversion operations have a significant impact on the level of the Union co-financing or a detrimental impact on the Union budget, the specific arrangements for conversion referred to in paragraph 1 shall provide, if appropriate, for a rate of conversion between the euro and other currencies to be calculated using the average of the daily exchange rate in a given period.

If no daily euro exchange rate is published in the Official Journal of the European Union for the currency in question, the responsible authorising officer shall use the accounting rate referred to in paragraph 4.

For the purposes of the accounts provided for in Articles 151 to 156 of the Financial Regulation and subject to Article 240 of this Regulation, conversion between the euro and another currency shall be made using the monthly accounting rate of the euro. That accounting exchange rate shall be established by the Commission’s accounting officer by means of any source of information he regards as reliable, on the basis of the exchange rate on the penultimate working day of the month preceding that for which the rate is established.

The results of the currency operations referred to in paragraph 4 of this Article shall be shown under a separate heading in the respective institution’s accounts.

The first subparagraph of this paragraph shall apply mutatis mutandis to bodies referred to in Article 208 of the Financial Regulation.

Without prejudice to specific provisions deriving from the application of sector-specific regulations, or from specific procurement contracts, grant agreements or grant decisions and financing agreements, the rate to be used for conversion between the euro and other currencies shall, in cases where the conversion is carried out by the responsible authorising officer, be that of the day on which the payment order or recovery order is drawn up by the authorising department.

In case of euro imprest accounts, the rate to be used for the conversion between the euro and other currencies shall be determined by the date of the payment by the bank.

For the regularisation of imprest accounts in national currencies, as referred to in Article 19 of the Financial Regulation, the rate to be used for the conversion between the euro and other currencies shall be that of the month of the expenditure from the imprest account concerned.

For the reimbursement of flat-rate expenditure, or expenditure arising from the Staff Regulations of Officials of the European Union and the Conditions of Employment of Other Servants of the European Union (hereinafter ‘Staff Regulations’) which is fixed at a ceiling, and which is paid in a currency other than the euro, the rate to be used shall be that which is in force when the entitlement arises.
