The rate referred to in Article 2 (1) (d) of Decision 8/376/EEC, Euratom, which shall be set within the budgetary procedure, shall be calculated as a percentage of the sum of the forecast GNP of the Member States in such manner that it fully covers that part of the budget not financed from customs duties, agricultural levies, VAT resources, financial contributions to supplementary research and technological development programmes, other revenue and, where appropriate, GNP financial contributions. This rate shall be expressed in the budget by a figure rounded off to the fourth decimal place.
