On Friday last week a US federal bankruptcy judge approved Enron's agreement to sell the US pipelines for $2bn (£1.6bn) to consortium CCE Holdings.
Enron chose the CCE offer following a closed-door auction, and the sale is expected to be completed by December.
Enron is also to sell another subsidiary business - Portland General Electric - leaving it with just one company - Prisma Energy International - which has small-scale pipeline and power assets in 14 countries.
