Within: Securities litigation - defense

Kirkland & Ellis LLP has a track record of success in securities class actions, shareholder derivative litigation, structured finance cases, and investigations and enforcement actions by the DOJ, SEC and other regulators. It also has one of the leading accounting liability practices. Mark Filip in Chicago leads the 50-partner securities and shareholder litigation practice. He recently acted for Caterpillar, Inc in numerous cases, which included In re Caterpillar Inc Securities Litigation, a putative class action alleging that the company made misleading statements about its compliance and business policies; the case was ultimately dismissed. Sandra Goldstein in New York is one the market's leading lights and she was part of a team that represented Mylan in a securities case relating to the company’s classification of the EpiPen under the Medicaid Drug Rebate Program. Matthew Solum and Yosef Riemer, both based in New York, acted for Bristol-Myers Squibb in three derivative actions arising from a settlement with the SEC for alleged FCPA violations. Chicago-based Joshua Rabinovitz is also recommended.
