This is excellent news for BP’s shareholders and I wish Ineos and its staff success for the future,” said Lord Browne, BP group chief executive. Notes to editors: · BP announced on 7th October 2005 that it would sell Innovene, its olefins, derivatives and refining group, to UK-based INEOS. The $9 billion cash sale included Innovene’s manufacturing sites, markets and technologies. · The European Commission cleared the proposed acquisition under the EU Merger Regulation on 9th December. · BP first announced the intention of separating its olefins and derivatives business from its petrochemicals portfolio in April 2004 with an initial public offering (IPO) as one, possible, disposal option. In the interim, it received a number of approaches from companies considering a trade sale.
