Samarco was required to disclose such information under the terms of a confidentiality agreement entered into as part of the negotiation process with the lenders.

As of 29 January, the parties have not reached agreement on the restructuring of Samarco’s unsecured financial obligations.

The restart of Samarco’s operations will occur only if it is safe, economically viable and has the support of the community. Resuming operations requires the granting of licences by state and federal authorities and community hearings, among other requirements.

BHP Billiton Brasil Ltda. and Vale S.A. each hold a 50% interest in Samarco.
