Article 2 
1. The undertakings referred to in Article 1 shall assemble the data provided for in Article 1(1) and (2) on 1 January and 1 July of each year. These data, drawn up in conformity with the provisions referred to in Article 3, shall be sent to Eurostat and the competent authorities of the Member States within two months. 2.
