NEW YORK, March 31 (Reuters) - Brazilian petrochemical company Braskem SA must face the main part of a shareholder lawsuit over its role in a massive bribery scandal that engulfed Brazil's state-owned oil company Petrobras SA , a U.S. judge has ruled.
In a decision made public on Friday, U.S. District Judge Paul Engelmayer in Manhattan said holders of Braskem's American depositary receipts may pursue claims that the company and former Chief Executive Carlos Fadigas defrauded them by concealing how bribery enabled the company to buy naphtha from Petrobras at below-market prices.
Naphtha is a key ingredient in petrochemicals, and the complaint said Braskem bought 70 percent of its naphtha from Petrobras.
Mark Gimbel, a lawyer for Braskem and Fadigas, said in an email the company is "committed to vigorously defending itself," and pleased that the judge dismissed several other claims.
Braskem's ADR price fell 20.3 percent on March 11, 2015 after the company was linked to bribery. The scandal arose from a probe called "Operation Car Wash," and led to dozens of prosecutions.
Last December, Braskem and Brazilian construction company Odebrecht SA, which together with Petrobras owns Braskem, agreed to pay at least $3.5 billion to settle bribery-related charges brought by U.S., Brazilian and Swiss regulators.
In his 55-page decision, dated March 30, Engelmayer said Braskem was not obligated in regulatory filings to address every factor in its naphtha pricing.
He also said, however, the ADR investors properly alleged that Braskem "cherry-picked for public consumption benign factors" while concealing the "elephant in the room": The substantial role that bribery played.
The company "was not at liberty to selectively omit what the fairly alleges as a central determination of that price: The corrupt arrangement Braskem had struck with the Petrobras officials it bribed," Engelmayer wrote.
Engelmayer dismissed claims that Braskem exaggerated its ethics and corporate controls in the filings.
He also dismissed all claims against Odebrecht because it lacked enough ties to the United States to justify being sued there. The judge also threw out claims against Fadigas' predecessor, Bernardo Gradin.
Boilermaker-Blacksmith National Pension Trust in Kansas City, Kansas is leading the lawsuit on behalf of ADR purchasers from July 15, 2010 to March 11, 2015.
"The core of the case was the naphtha pricing statements, and I am pleased to see that was upheld," the investors' lawyer Steven Toll said in an interview. "The case will go forward."
Michael Carlinsky, a lawyer for Odebrecht, said he was pleased his client was dismissed from the case.
