Citigroup and Credit Suisse have won the lead roles as joint bookrunners on the first international bond from TNK-BP, the Russian-Anglo oil producing company and second largest in Russia after Rosneft. UBS and BNP Paribas will be joint lead managers.

The expected benchmark sized dollar bond, which typically means its worth at least $500m (€391m), is the first from the merged company since British oil company BP completed the $6.75bn acquisition in September 2003.
