The judge, Gilberto Clovis Farias Matos, said the request by OSX and two of its three non-traded subsidiaries, OSX Construção Naval Ltda and OSX Serviços Operacionais Ltda, met the criteria of Brazil's corporate legislation, according to a statement issued by the press office of the Justice Tribunal of Rio de Janeiro state.

As such, the statement said, the court has the authority to shield them from creditors. In his decision to accept the bankruptcy petition, Farias Matos wrote that the companies "cover a market niche with heavy investments from international creditors, hundreds of jobs, suppliers and service providers that carry out an important function in the economy."

In the meantime OSX and the two units, one which owns the OSX shipyard north of Rio de Janeiro and the other which provides ship and vessel-operations services, will each have to develop its own individual recovery plan and its own unique creditor list. The requirement, the judge ruled, is necessary even if the plans are considered by the group to be interdependent or identical.

The case is before the 4th Corporate Division of the Rio de Janeiro State Justice Tribunal in Rio de Janeiro, case number 0392571-55.2013.8.19.0001.
