Stora Enso Oyj Stock Exchange Release 9 August 2007 at 07.00 GMT The co-determination negotiations that started in June at Stora Enso's Kemijärvi Pulp Mill in Finland concerning temporary lay-offs of personnel due to shortage of wood have been concluded. The shortage of wood anticipated in the early autumn has been alleviated through increased domestic wood supply so the immediate need for lay-offs has been averted. The outlook for the wood supply in Finland later in the autumn and winter remains uncertain at this point. This causes a risk of temporary lay-offs later in the year. Furthermore, increased wood costs are aggravating the operating environment.
