Ms. Gilden is an industry leader and client champion, spearheading some of the most novel securities disputes in the financial markets, resulting in aggregate recoveries in excess of several billion dollars for investors. Her guiding principle – those who commit fraud on the financial markets should be held accountable.

Ms. Gilden has been court appointed lead, co-lead or executive committee counsel on numerous high-profile securities cases, including MF Global, in which the U.S. Court of Appeals for the Second Circuit held that companies that make false, misleading statements cannot hide behind risk disclosures in an attempt to escape liability, and for which she was named in the National Law Journal’s Hot Plaintiffs Firm of the Year; and IntraLinks – one of the first securities class actions to be certified following the Supreme Court’s decision in Halliburton II, providing a roadmap for obtaining class certification to other cases. She is currently Co-Lead Counsel in two groundbreaking antitrust lawsuits involving two of the world’s largest financial markets.

Ms. Gilden began her career at the Securities and Exchange Commission in the Enforcement Division, spending five years investigating and litigating cases involving securities fraud.  Prior to joining Cohen Milstein in 2007, Ms. Gilden served as the head of the securities class action practice at a prominent mid-sized Chicago law firm and the vice chair of its class action department. 

Representative Matters:

  • Interest Rate Swaps Market Manipulation Litigation (S.D.N.Y.): Ms. Gilden represents the Chicago Public School Teachers’ Pension Fund and other institutions in a groundbreaking putative class action, charging 12 Wall Street banks with conspiring to engineer and maintain a collusive and anti-competitive stranglehold over the interest rate swaps market – one of the world’s biggest financial markets. Cohen Milstein is Co-Lead Counsel in this case, which is now in active discovery.
  • Treasuries Market Manipulation Litigation (S.D.N.Y.): Ms. Gilden represents the Cleveland Bakers and Teamsters Pension and Health and Welfare Funds and other institutions in a groundbreaking putative antitrust securities class action, alleging two dozen financial institutions with an inside role at the auction for U.S. Treasuries, conspired to manipulate yields and prices to their own benefit.

  • Plumbers & Pipefitters National Pension Fund v. Davis, et al. (S.D.N.Y.): Ms. Gilden represents Plumbers & Pipefitters National Pension Fund and other investors, in this high-profile, putative securities class action involving PSG’s failure to disclose that its growth was not based on sustainable “organic growth” as represented, but was driven by the company’s manipulative and coercive sale practices, which included pulling orders forward and forcing customers to increase their orders without regard for market demand. The SEC and Canadian authorities subsequently initiated investigations, and PSG filed for bankruptcy. Cohen Milstein is sole Lead Counsel in this case and successfully defeated defendants’ motion to dismiss, which the court largely denied on April 14, 2020.
  • Credit Suisse Group AG Securities Litigation (S.D.N.Y.): Ms. Gilden is representing the International Brotherhood of Teamsters Local No. 710 Pension Plan in a securities class action against Credit Suisse Group AG, involving misrepresentations of its trading and risk limits, and subsequent accumulation of billions of dollars in extremely risky, highly illiquid investments, including the surreptitious accumulation of nearly $3 billion in distressed debt and U.S. collateralized loan obligations (“CLOs”). Cohen Milstein is Co-Lead Counsel.  On July 10, 2020, the parties agreed to a $15.5 million settlement, pending court approval.

(E.D.N.Y.): Cohen Milstein is sole Lead Counsel representing the Midwest Operating Engineers Pension Trust Fund in a securities class action against Alkermes, a global biopharmaceutical company, for material misrepresentations about the likelihood of approval for a drug in development.  Although the U.S. Food and Drug Administration (FDA) repeatedly shared concerns about the drug’s viability with the company, Alkermes represented to investors that FDA approval was imminent. Defendants’ motion to dismiss is fully briefed and awaiting decision.
  • Pluralsight, Inc. Securities Litigation (D. Utah): Cohen Milstein is sole Lead Counsel representing the Indiana Public Retirement System and the Public School Teachers’ Pension and Retirement Fund of Chicago in a securities class action against Pluralsight, Inc, a provider of cloud-based and video training courses.

Securities Litigation (S.D.N.Y.):  Ms. Gilden represented Plumbers and Pipefitters National Pension Fund and Metropolitan Water Reclamation District Retirement Fund and achieved a $16.96 million settlement against ITT and two of its officers.

  • Singh et al. v. Orthofix International NV (S.D.N.Y.): Ms. Gilden represented Plumbers and Pipefitters National Pension Fund and reached an $11 million settlement against this medical device company headquartered in Curacao, Netherlands Antilles, despite significant logistical obstacles during investigation and discovery.

Cook Cty., Ill.): Ms. Gilden represented the City of Chicago in a high-profile lawsuit in Cook County Circuit Court, alleging that Expedia,, Orbitz, Priceline and Travelocity failed to properly remit hotel taxes to the City of Chicago for hotel bookings. Expedia, the last remaining defendant, appealed a $29 million judgement, and settled on appeal and after the conclusion of briefing. In total, the City of Chicago recouped $23.6 million in back taxes and penalties, and these defendants now collect and remit to the City of Chicago taxes on the mark-up of the room bookings.
