The American Alltel is believed to be losing its chance of winning a USD100m supply contract for a centralised computer system for bank PKO BP. At the same time rumours are abounding of Gdynia based systems integrator Prokom increasing its stake in Softbank. Softbank was to have been Alltelís partner in updating the IT network at PKO BP. Such rumours did not hurt Softbankís stock price on Monday which increased by 4.2 percent.
