NEW YORK (TheStreet) -- North Atlantic Drilling (NADL) shares are down 5.1% to $9.28 on Thursday after CEO John Fredriksen said that international sanctions against Russia may affect a $4.25 billion deal with OAO Rosneft, according to Bloomberg.
OAO Rosneft is an intergrated oil company that is owned by the Russian government.
Rosneft and North Atlantic drilling signed five-year contracts for six offshore rigs in July, days before the European Union broadened its sanctions against the country to include its energy sector in response to Russia's incursion into Ukraine.
