POLAND Back in December last year, the management of Hydrobudowa Polska, part of Grupa PBG, wrote to the company's shareholders and investors. The letter began: Having assessed the current financial condition of Grupa HBP, we can say that we are in good shape, while the prospects of the market which we operate in provide the basis for looking to the future with optimism. However, in June this year the contractor of such projects as the National Stadium in Warsaw, the PGE Arena in Gdańsk, the Municipal Stadium in Poznań and the A1 motorway, announced that three companies from Grupa PBG, PBG, Hydrobudowa Polska and Aprivia had decided to file for bankruptcy, subject to arrangements, with creditors at the Poznań district court.
