A class action complaint was filed against Verasun on November 10, 2010 out of the United States District Court for the Southern District of New York. Shareholders of Verasun filed this class action lawsuit and claim that the firm failed to disclose information about the company that would of made shareholders aware of certain risks that Verasun was undertaking at the time. The failure to disclosure statements in question were made between March 12, 2008, to Sept. 16, 2008. The plaintiffs are alleging that VeraSun knew or should have known of these risks and failed to inform its investors about these risks and the consequences should the risks materialize.
This is a prefect example of a failure to disclose lawsuit litigation that continues to happen today. See http://www.classactionsettlementnews.com/juniper-networks-securities-class-action-lawsuit-complaint, very similar complaints.
