The deal, that was linked on May 27, 2011, covered selected advanced glazing solutions. The company added that the non-satisfying development of the cooperation between both parties already led in the interim financial statements for the 9m ended September 20, 2011 to an impairment loss of 3.6M/Euros on the distribution rights relating to the deal. Also, the determination of this impairment loss took into account potential further payments which CSG's Management Board had estimated at 2M/Euros.
