On 4 March 2011 the Commission opened an in-depth investigation under the EU Merger Regulation into the planned acquisition of sole control by UPM-Kymmene Corporation (UPM) of Myllykoski Corporation (Myllykoski,), and Rhein Papier GmbH (Rhein Papier), all active in the paper industry. The Commission’s initial market investigation indicated that the proposed merger could raise serious competition concerns, in particular because the merged entity’s behaviour may not be sufficiently constrained by competitors on the market for magazine paper. The Commission now has 90 working days, until 19 July 2011, to take a final decision on whether the merger would significantly impede effective competition in the EU.
