PDG filed for bankruptcy protection in February after citing a severe cash crunch and onerous debt of 7.3 billion reais ($2.33 billion). It presented an in-court reorganization plan on June 7.

Banks Caixa Econômica Federal, Banco do Brasil SA (>> Banco do Brasil SA) and Itaú Unibanco Holding SA (>> Itau Unibanco Holding SA) and the company agreed to leave segregated assets outside the in-court reorganization, the filing said.

PDG has struggled with cost overruns since it purchased smaller rival Agre Participações SA in May 2010, while also dealing with Brazil's deep recession over the last two years.
