Debevoise & Plimpton LLP partners Arian June, Winston Paes and Douglas Zolkind have authored a chapter entitled “Cooperating with US government investigations: the risks and rewards” in Americas Investigations Review 2026, which is published by Global Investigations Review.

The chapter provides a comprehensive analysis of the key challenges companies face in DOJ, SEC, CFTC, and OFAC investigations. It highlights critical early decisions – assessing the investigation’s origins, determining whether to conduct an internal review and weighing the risks and benefits of cooperation. It also addresses preserving attorney–client privilege and offers strategies for managing parallel investigations across multiple domestic and international authorities.
