Colbert v. Rio Tinto PLC

Background

Anton Colbert filed a proposed class action against Rio Tinto PLC, Rio Tinto Limited, Thomas Albanese, and Guy Robert Elliott. He alleged violations of Section 10(b) of the Securities Exchange Act of 1934 and Securities and Exchange Commission Rule 10b-5 against all defendants, and Section 20(a) of the Exchange Act against Albanese and Elliott.

The lawsuit concerned Rio Tinto’s 2011 acquisition of Riversdale Mining Limited and the resulting Rio Tinto Coal Mozambique project. The complaint alleged that Rio Tinto valued the project at approximately $3.7 billion even though later internal valuation models produced substantially negative values. In November 2012, Albanese described the relevant coal-mining area as a “long-term opportunity” with potential to grow beyond 25 million tons of coal per year. Rio Tinto later announced a $3.269 billion impairment of the project, reported a net loss of almost $3 billion, and published audited financial statements explaining the impairment. The complaint alleged that these events caused Rio Tinto’s American Depositary Receipt price to decline.

The court had previously dismissed the complaint under Federal Rule of Civil Procedure 12(b)(6), which permits dismissal when a complaint does not adequately state a legal claim. After the Court of Appeals remanded the case, the district court considered only whether the “long-term opportunity” statement was actionable.

Issue and legal standard

To state a claim under Section 10(b) and Rule 10b-5, a private plaintiff must allege, among other things, a material misstatement or omission, fraudulent intent, reliance, and loss causation. Loss causation means a direct link between the alleged misconduct and the plaintiff’s economic loss. The plaintiff must allege that the statement or omission concealed something from the market and that disclosure of the concealed truth caused the security’s value to decline.

Analysis

The court held that Colbert had not adequately alleged loss causation for the “long-term opportunity” statement. The alleged partial disclosures in January, February, and March 2013 announced the impairment, Rio Tinto’s net loss, and the audited details of the loss. But the court found that those disclosures did not tell the market that Albanese’s earlier statement was false or inaccurate, did not reveal the alleged fraud, and did not suggest that Rio Tinto should have recorded the impairment earlier.

Because Colbert alleged that the impairment news itself caused the decline in Rio Tinto’s share price—not that disclosure of the alleged fraud caused the decline—the court found that the complaint did not state a Section 10(b) claim based on the “long-term opportunity” statement.

Disposition

The court dismissed Colbert’s Section 10(b) claim concerning the “long-term opportunity” statement for failure to state a claim. It also stated that, for the reasons given, Colbert’s complaint was dismissed. The order did not state that the dismissal was with or without prejudice.
