28.8.2014 Official Journal of the European Union L 255/1 II (Non-legislative acts) REGULATIONS COMMISSION DELEGATED REGULATION (EU) No 906/2014 of 11 March 2014 supplementing Regulation (EU) No 1306/2013 of the European Parliament and of the Council with regard to public intervention expenditure THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Regulation (EU) No 1306/2013 of the European Parliament and of the Council of 17 December 2013 on the financing, management and monitoring of the common agricultural policy and repealing Council Regulations (EEC) No 352/78, (EC) No 165/94, (EC) No 2799/98, (EC) No 814/2000, (EC) No 1290/2005 and (EC) No 485/2008 (), and in particular Article 20(2) and (3) thereof, Whereas: (1) In accordance with point (a) of Article 4(1) of Regulation (EU) No 1306/2013, intervention measures regulating agricultural markets are to be financed by the Union under the terms of the sectoral agricultural legislation. As regards public intervention measures, the amount to be financed by the Union is determined by the annual accounts drawn up by the paying agencies. (2)  Public intervention expenditure may vary substantially. It is therefore necessary to specify for each category of operation which expenditure is eligible for Union financing and, in particular, under what terms that expenditure can be covered. For this purpose, eligibility conditions and the methods for calculating eligible expenditure should be laid down. It should be further specified when such expenditure is to be booked on the basis of the elements actually recorded by the paying agencies or on the basis of standard amounts established by the Commission. (3)  To allow Member States whose currency is not the euro to consolidate their expenditure and costs in their national currency and in euro in a harmonised way, the terms under which public storage operations are recorded in their accounts and the exchange rate applicable should be specified. (4)  The valuation of public storage operations also depends on the type of operations and on the applicable sectoral agricultural legislation. A general rule should therefore be established providing that the value of the quantities bought in and sold is to be equal to the sum of the payments and receipts made or to be made for physical operations, together with specific rules and special cases to be taken into consideration.
