Securities Litigation

Cahill lawyers have been on the front lines of large-scale securities litigation for nearly a century, focusing on the leading issues of the day. Recent matters include the alleged manipulation of the US Dollar London Inter-Bank Offered Rate (LIBOR) and other reference rates, and multi-billion dollar federal and state court class and individual actions involving subprime and structured finance products (including RMBS, CDO, REMIC, SIV and trust preferred securities), as well as "dark pools” and high-frequency trading. Our recent caseload has also included victories in significant securities actions in federal and state courts throughout the United States, including a unanimous jury verdict in the trial of a nationwide securities class action alleging fraud in a bond offering. Our Securities Litigation practice is top-ranked by Chambers USA, The Legal 500 and Benchmark Litigation. In 2022, members of Cahill’s trial team were recognized by The American Lawyer as Litigators of the Week for their precedent-setting win on behalf of Credit Suisse in a foreign exchange markets class action following an eight-day jury trial in the SDNY. In 2019, Law360 recognized Cahill’s Securities practice as a Practice Group of the Year.

We have handled some of the most significant regulatory and enforcement matters for global banks and transnational companies. Our lawyers have extensive experience conducting multinational investigations involving alleged violations of the Foreign Corrupt Practices Act (FCPA), The Office of Foreign Assets Control (OFAC) regulations, other commercial anti-bribery laws and the Bank Secrecy Act. We also have a long track record of conducting antitrust and price fixing investigations in markets including healthcare, pharmaceuticals, automotive, paper products, homebuilding and tobacco. We are also called upon to assist in resolving complex financial disputes through alternative dispute resolution and in private proceedings.

Our team includes former federal prosecutors, alumni of the Securities and Exchange Commission, and other lawyers who joined Cahill following distinguished careers in the Department of Justice, Department of the Treasury, Commodity Futures Trading Commission, and other government agencies and commissions.

We represent issuers, underwriters, bank lenders, placement agents, officers and directors, accountants, lawyers and investors in large-scale securities litigation and investigations throughout the world. We have represented participants in complex securities class action litigation and parallel governmental investigations involving financial exposures in the billions of dollars.
