A Brazilian Senate committee is expected to recommend that 12 current and former executives of Vale , including CFO Luciano Siani and former CEO Fabio Schvartsman, face criminal indictments for a fatal dam disaster in January. The rapporteur of the committee proposed the indictments Tuesday after a two-and-a-half-month congressional inquiry into the causes of the dam break that left at least 246 people dead and unleashed a sea of mud over the city of Brumadinho, where Vale had an inactive iron ore mine. His report says the company was negligent and its risk and compliance controls were flawed.
