. The £2.8bn (US$4.5bn) ($ billion today) price tag for FORE and the £1.3n spent on Reltec a month earlier took a heavy toll on Marconi following the burst of the bubble in 2000/2001. In July 2001 Marconi plc suffered a 54% drop in its share price following suspension of trading of its shares, a profits warning and redundancies. The company survived following a relaunch as Marconi Corporation plc in a debt-for-equity swap whereby the firm's creditors received 99.5% of the new company's shares. In 2006, Ericsson purchased most of Marconi, including the part that used to be FORE Systems. In 2008, Ericsson closed the Warrendale plant and sold off the corporate HQ.
