Banco Bradesco SA and Itaú Unibanco Holding SA are the private banks with the most exposure to Odebrecht SA, Exame reported on Aug. 27, citing a new court document listing the construction and engineering conglomerate's creditors.

Odebrecht owes Bradesco about 8.38 billion reais and Itaú 7.71 billion reais in the form of unsecured loans, according to documentation provided by the industrial conglomerate.

The conglomerate also has about 1.08 billion reais in unsecured credit with Banco Santander (Brasil) SA, on top of 15 million reais of collateralized debt and 77.7 million reais of claims related to labor laws.

Other banks listed in the document are Banco Votorantim SA, with claims of 109.7 million reais, and Banco ABC Brasil SA, with 103.5 million reais.

The list of creditors was forwarded to São Paulo courts along with Odebrecht's judicial recovery plan. According to CEO Luciano Guidolin, reducing Odebrecht's obligations will allow "productive activity, job preservation and value creation for all stakeholders."

One of the major companies embroiled in Brazil's sprawling Lava Jato, or Car Wash, corruption investigation, Odebrecht said it plans to restructure 51 billion reais of debt.

As of Aug. 27, US$1 was equivalent to 4.18 Brazilian reais.
