Brazilian mining company Vale was accused by the Securities and Exchange Commission (SEC) on Thursday of making false and misleading safety audit and disclosure claims prior to the January 2019 collapse of its Brumadinho dam.

Public documents filed with the SEC between October 2016 and December 2018 claimed, “Vale had not identified any anomalies with the dams and that its independent stability declarations were in compliance with Brazilian regulations and international best practices,” the agency stated in its complaint.
