SAO PAULO, Nov 5 (Reuters) - Brazilian petrochemical producer Braskem SA is open to a variable-pricing formula for its naphtha supply contract with state-run oil company Petrobras, but talks are not heading in that direction, Chief Executive Carlos Fadigas said on a Thursday earnings call.
Braskem and its second-biggest shareholder, known formally as Petroleo Brasileiro SA, reached an interim deal last week extending their naphtha supply contract for another 45 days. (Reporting by Alberto Alerigi Jr. Editing by W Simon)
