Article 5
1. Italy shall inform the Commission of the date on which the Centre begins operations within 15 days of that date. 2. By 30 June every year Italy shall supply the Commission with a detailed report on the previous calendar year's activities. That report shall contain the following information: - a list of the undertakings permitted to operate at the Centre, - the number and the overall financial volume of the transactions carried out, broken down into the classes of business qualifying for tax concessions, - the average rate of interest applied at the Centre for each class of business qualifying for tax concessions, - the total amount of the tax concessions actually granted, broken down by category of tax; the tax benefit must be shown, being the difference between the amount of each tax actually paid on the transactions to which the special scheme applies and the amount which would have been payable under the ordinary Italian tax arrangements. 3. Italy shall without delay supply the Commission with any detailed information on the operation of the Centre which the Commission may request. If the Commission finds that the inspection measures taken are ineffective, and especially if the funds are directly or indirectly reinvested in countries outside eastern Europe, Italy shall take such inspection measures as the Commission shall indicate.
