Where in a Member State more than 70 % of farms operated by way of main occupation already keep accounts satisfying the provisions of paragraph 2, that Member State shall not be obliged to introduce such a system. The system shall involve granting to farmers whose main occupation is farming and who apply therefor and aid of 450 units of account, spread over at least the first four years during which management accounts are kept on their farms. 2. The keeping of accounts shall: (a) comprise: - the preparation of annual opening and closing valuations; - the systematic and regular recording over the accounting year of the various transactions in cash or in kind concerning the farm business; (b) conclude with the presentation each year of: - a description of the general characteristics of the farm business, and in particular of the factors of production employed; - a detailed balance sheet (assets and liabilities) and trading account (expenditure and income); - the necessary data, including in particular the earned income per man-work unit and the farmer's income, for assessing the efficiency of the management of the farm business as a whole and the profitability of the main enterprises of the business. 3. Where a farm is chosen by the authorities appointed by Member States for the collection of accountancy data for purposes of information and scientific study, in particular within the framework of the EEC accountancy data network, and the farmer is in receipt of aid as provided for in paragraph 1, he must undertake to make available to those authorities, under conditions of anonymity, the accountancy data relating to his farm.
