According to the complaint the plaintiff alleges on behalf of purchasers of Rio Tinto plc (ADR) (NYSE: RIO) common shares between March 16, 2012 and November 14, 2016, that the defendants violated Federal Securities Laws. More specifically, the plaintiff claims that between March 16, 2012 and November 14, 2016, the defendants made false and/or misleading statements and/or failed to disclose that Rio Tinto plc violated anti-corruption laws in connection with its operations with respect to the Simandou project, that the foregoing violations would expose the Company to significant scrutiny and large fines, and that as a result of the foregoing, Rio Tinto plc’s public statements were materially false and misleading at all relevant times.
