Successfully Navigated DOJ Antitrust Concerns for NORPAC Foods Bankruptcy

Tonkon represents NORPAC Foods, Inc. and its affiliates as debtors-in-possession in their chapter 11 bankruptcy cases. The case has included two major asset sales, the first of which caused the United States Department of Justice Antitrust Division to withhold approval and investigate potential anticompetitive impacts and other antitrust violations. Tonkon worked with the DOJ through its investigation by submitting voluntary document productions, offering key witnesses for interviews, and submitting white papers on various legal issues. The DOJ eventually closed its investigation without taking any action and the sale proceeded without incident.
