In December 2012, the insolvency proceedings opened against the Graupner Beteiligungen GmbH and in the Esslingen District Court initiated Shield process . The application for the procedure was placed on the 12 February 2013. Obviously this "hard cut" did not bring the hoped-for success. The goal was according to the management, to complete the restructuring of the company during the three-month Shield process by March and to avert insolvency. This has failed despite the efforts until February 22, 2013.
