Representative Experience

  • Represented preferred stockholders in Johnson v. W2007 Grace Acquisition I, Inc., No. 2:13-cv-2777 (W.D. Tenn.), an action against a once-public, widely-held billion-dollar real estate investment trust (REIT) that was taken private and had gone “dark” on its preferred stockholders for over five years. Preferred stockholders received a recovery of $72 million representing par plus interest.
  • Represented bondholders in Roth v. The Phoenix Companies, No. 650634/2016 (N.Y. Sup. Ct.) against The Phoenix Companies, a publicly-traded insurer that had entered into a going-private transaction and sought to amend the bond indenture to limit financial reporting obligations to bondholders. The settlement secured ongoing financial reporting akin to that of a public company for bondholders as well as third parties, such as prospective buyers, brokers, market makers and analysts. This preserved the liquidity of the bonds and enhanced the bonds’ value by millions of dollars. The Court stated that the settlement was “outstanding” and provided “expeditious beneficial relief for the class that affords them material remedial disclosures…. Class counsel performed substantial work and obtained an extremely favorable result for the class.”
  • Represented stockholders in TRSL v. Greenberg, et al., No. 20106 (Del. Ch.), and successfully challenged the findings of a special litigation committee.  After engaging in hard-fought litigation, the matter settled for $115 million on the eve of trial.
  • Represented stockholders in In re Parmalat Sec. Litig., MDL 04‐1653 (S.D.N.Y.) during which the reference was successfully withdrawn from the U.S. Bankruptcy Court, which allowed stockholders to pursue debtor Parmalat in the U.S. District Court for the Southern District of New York, and led to the recovery of over $70 million and an additional $30 million from Parmalat’s cohorts in one of the most infamous securities frauds in Italy’s history.
  • Represented shareholders in Delaware County Retirement Fund v. Portnoy, No. 1:13-cv-10405 (D. Mass.), which presented the issue of whether an onerous, one-sided arbitration bylaw that had a chilling effect on the shareholders ability to bring litigation was valid and permissible by law.
  • Represented investors in In re American International Group, Inc. Consolidated Derivative Litig., No. 769 (Del. Ch.) ($90 million recovery for AIG), In re Hollinger Int’l Sec. Litig., No. 04-CV-0834 (N.D. Ill.) ($37.5 million settlement for defrauded investors), and numerous other actions involving Barnes & Noble, BioScrip, Cablevision, Constellation Energy Group, Covad Communications, DVI Inc. and Mattel.
  • Represented consumers in In re 24 Hour Fitness Prepaid Memberships Litigation, No. 4:16-cv-01668 (N.D. Cal.) that was settled for a full recovery, the value of which is projected to exceed $35 million (final approval of settlement pending).

Search Tips

Our Web site's search function employs a variety of techniques to help you make the most of your queries. In this tips section we use square brackets [ ] to signal queries, so [antitrust and litigation] is one query, while [antitrust] and [litigation] are two.

  • Exact phrases: Eliminate unnecessary search results by surrounding your search phrase with quotation marks. Placing ["project finance"] in quotes will return specific results and discard additional results that simply have the words "project" and "finance" peppered on a page.
  • Wildcard symbol: If you're not exactly sure how a piece of information you want is phrased, use the following symbol (*) as a word root expander. A search for [child*] will find not only "child," but also results with words like "children" and "childhood."
