Cal. 2014), a securities class action brought against corporate officers for making alleged misrepresentations that failed to disclose problems with the company’s new operating systems, including significant invoicing delays, and the resulting liquidity constraints.

The case was highly technical, involving several experts, more than 3 million pages of document production, 26 depositions, and numerous dispositive motions. The case settled just weeks before trial for a recovery that recouped approximately 35.6% of investors’ losses, despite the company being in bankruptcy.

Colo. 2012), a securities class action against former officers and directors of Delta Petroleum Corporation for allegedly misrepresenting the company’s financial condition and the value of its assets.
