Use of new company names

During the reporting year, most of the companies in the Group were renamed to incorporate the Alpiq brand name. At the end of December 2009, the two principal companies, Olten-based Aare-Tessin Ltd. for Electricity (Atel) and Lausanne-based Energie Ouest Suisse (EOS) SA, also changed their names to Alpiq Ltd. and Alpiq Suisse Ltd. respectively. The financial review and following financial statements of the Alpiq Group and Alpiq Holding Ltd. include some information relating to past events concerning these principal companies. Where meaningful, the former company names have been used.

In the list of subsidiaries and investments, all significant companies in the Alpiq Group are shown under their new names.
