RK&O's litigators fight for our clients in complex proceedings in the United States and abroad. Our veteran litigators draw upon a sophisticated understanding of the law, the regulatory environment and the business considerations underlying a dispute to defend our clients in:

  • Class action and shareholder derivative cases
  • Multi-district proceedings
  • Parallel state and federal lawsuits
  • Cases with parallel regulatory and criminal proceedings or investigations
  •  more +

RK&O understands our clients’ businesses. Our hedge fund and financial services clients turn to us for our industry-specific knowledge, which allows us to solve their problems in a cost-efficient manner. Senior management of public and private companies and public company directors trust us to defend them in private litigation because of our detailed understanding of the host of corporate governance, regulatory and potentially criminal issues that they face.

Our litigators handle an array of complex securities and shareholder actions, including those alleging breach of fiduciary duty, fraud, misrepresentation and nondisclosure. Currently, we are defending London-based ICAP in class actions alleging efforts to manipulate USD LIBOR, Yen LIBOR, Euroyen TIBOR and Euribor. We recently represented all the individual defendants in the residential mortgage-backed securities litigations brought against Bank of America and Merrill Lynch by the Federal Housing Finance Agency in the Southern District of New York and MassMutual in the District of Massachusetts. We also represented the chief financial officer of MF Global in a securities and commodities class action filed after the brokerage filed bankruptcy proceedings.

Our experience and expertise is fortified by our collaborative relationship with our regulatory and corporate colleagues, bringing to bear an unusually broad range of expertise to solve our clients’ securities-related problems.
