  • Public Employees’ Retirement System of Mississippi v. TreeHouse Foods, Inc., No. 1:16-CV-10632 (N.D. Ill.)   As Lead Counsel, Wolf Popper represented the Public Employees’ Retirement System of Mississippi (“PERS”) in this securities class action against TreeHouse Foods, Inc. and certain of its senior executives on behalf of investors who purchased TreeHouse securities during the period February 1, 2016 through November 2, 2016. The complaint alleged that TreeHouse and certain of its senior executives violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, by issuing a series of false and misleading statements arising out of the Company’s acquisition of ConAgra Foods, Inc.’s private brands operations, for $2.7 billion in cash in February 2016.

  • Belfiore v. The Procter & Gamble Co., 14-cv-4090 (E.D.N.Y.),   his consumer class action litigation, Belfiore v. The Procter & Gamble Co., 14-cv-4090 (E.D.N.Y.), alleges that Procter & Gamble has been representing that its Charmin Freshmates flushable wipes are “flushable” and “safe for sewer and septic systems” when in fact they do not break down sufficiently and, as a result, cause serious problems for septic tanks and household plumbing.  Judge Weinstein initially certified the class of New York consumers in 2017.  After remand from the Second Circuit, Judge Weinstein held four days of hearings in 2019 where Wolf Popper presented expert testimony on using hedonic regression to calculate class wide damages. Judge Weinstein then confirmed his prior decision and certified the class once more, crediting plaintiff’s expert over three prominent defense experts who testified at the hearing.  After defeating the motion to dismiss and repeatedly defeating defendant’s attacks on class certification, Wolf Popper negotiated a settlement with P&G where class members are eligible to receive up to $50.20 per household and P&G agreed to remove the representation that Freshmates are “safe for sewer and septic systems.”  The court approved the settlement on July 23, 2020., 2020
  • Amedisys, Inc. Securities Litigation, No.: 10-CV-00395 (M.D. LA.)       As Co-Lead Counsel, Wolf Popper represented one of the Co-Lead Plaintiffs, the Puerto Rico Teachers Retirement System, in this securities class action. The complaint alleged that Amedisys hid a Medicare fraud scheme by which Amedisys improperly inflated Medicare reimbursements by pressuring and intimidating nurses and therapists to provide unnecessary treatment to trigger higher fees, and that while committing this alleged Medicare fraud, Amedisys made several false and misleading statements that artificially inflated the price of its stock.The District Court initially granted Defendants’ motions to dismiss the complaint. However, Co-Lead Plaintiffs successfully appealed that dismissal to the U.S. Court of Appeals for the Fifth Circuit, which reversed the dismissal and remanded the case to the District Court for further proceedings. See 769 F.3d 313 (5th Cir. 2014). Defendants’ petition for a writ of certiorari to the Supreme Court and subsequent motion to dismiss the amended complaint were both denied. The parties reached a settlement in the amount of $43.75 million, which was approved by the Court on December 20, 2017., 2017
  • JPMorgan Acceptance Corp. I (JPMAC) Securities Litigation, No.: 2:08-cv-01713 (E.D.N.Y.)      As Co-Lead Counsel, Wolf Popper represented the Public Employees’ Retirement System of Mississippi (“MissPERS”) in this securities class action against JPMorgan Acquisition Corp. (“JPMAC”), certain individuals employed by it or its affiliates, and JP Morgan Securities, Inc., on behalf of investors who purchased mortgage-backed securities issued by 26 separate offering trusts. The class action was brought on behalf of investors who purchased certain mortgage passthrough certificates (mortgage-backed securities) across 26 offerings, with an initial face value of approximately $23 billion. MissPERS alleged in its consolidated complaint that the offering documents pursuant to which the JPMAC securities were sold contained misrepresentations and omitted to disclose information concerning the underwriting of the mortgage loans serving as collateral for the securities. Defendants’ motion to dismiss was denied in substantial part. On July 24, 2014, the court approved the settlement of the action for $280 million, one of the largest settlements of a class action against the issuers of mortgage-backed securities. The Court found that “the representation of both sides was obviously very vigorous. The plaintiffs, I know, expended efforts in terms of pursuing the investigation, the theories, the research and the advocacy.” The Court also noted that the action “was a difficult case. Certainly in the beginning, at the time when some of the principles, the legal principles that are applied in this case, in any cases related to mortgage-backed securities, was not well established. They did yeomen’s work, I think, in trying to establish some of those principles. . . . [T]his is a good result in this particular case.”, 2014
