Norton Rose advised state-owned Angolan oil company Sonangol on its $1.15bn (£700m) fundraising – the African state’s largest ever oil-backed financing transaction.

The deal sees the Angolan Government take pre-payment of crude oil for the next six years. The transaction was fully underwritten by BNP Paribas, Natexis Banques Populaires, Societe Generale and Banque Belgolaise – advised by Clifford Chance (CC).
