On 2 June 2003, shares in Abertis Infraestructuras, S.A. –abertis– were admitted for listing. abertis is the company resulting from the merger of Acesa Infraestructuras, S.A. (ACESA) and Aurea Concesiones de Infraestructuras, S.A. (AUREA).
abertis forms part of the Ibex 35 and, following the merger operation, has increased its weight in the index.
At the close of the 05/30/03, last trading session in share under the name ACESA, the company's capitalisation on the index stood at 3,827 million euros (total capitalisation, Class A and Class B shares: 4,293 million euros).
