Assets of ExxonMobil and ConocoPhillips were expropriated in 2007 after they declined to restructure their holdings in Venezuela to give PDVSA majority control, Total, Chevron, Statoil and BP agreed and retained minority shares in their Venezuelan projects. Reaching a settlement with ExxonMobil has proven difficult; Venezuela offered book value for ExxonMobil's assets and ExxonMobil asked for as much as $12 billion. This matter and others including the claims of ConocoPhillips remain before the World Bank’s International Centre for Settlement of Investment Disputes.
