Two more subsidiaries of the Signa Group, owned by Austrian real estate investor René Benko, have filed for insolvency. Signa Financial Services and Signa REM Germany submitted corresponding applications to the Charlottenburg District Court. Benko's extensive network of companies also includes the German department store chain Galeria Karstadt Kaufhof. Insiders expect that other Signa companies will file for insolvent. The case of the Elbtower, which also belongs to the Benko empire, could still grow into a political scandal.
