Shares in the Polish builder Polimex Mostostal rose on the Warsaw’s stock exchange on Monday following news that its chairman had been dismissed by the supervisory board. By noon, Polimex shares had climbed by as much as 4.55 percent, the business website parkiet reports. As expected, vice-president Robert Oppenheim is to be in charge of Polimex until a new head is appointed. “We wouldn’t have to handle this problem if so many construction companies weren’t failing, considering our contract portfolio,” Oppenheim told Polish Press Agency, while announcing that a new restructuring plan would be introduced for the company.
