Corteva and Vylor were sued in Indiana state court by 15 US states and Guam, which allege that Corteva's spinoff of its seed business was designed to avoid tens of billions of dollars in legacy liabilities tied to PFAS (a group of persistent industrial chemicals). The states say Vylor received the profitable business without taking on liabilities linked to DuPont's alleged environmental pollution and potential health risks to millions of Americans. Corteva completed the spinoff into a separate publicly traded company on Thursday. The case argues that the transaction could place assets beyond the reach of creditors pursuing claims against former DuPont companies.
