From the Overview: "On January 13, 2020, the Department of the Treasury issued final regulations after public notice and comment to implement key parts of the Foreign Investment Risk Review Modernization Act (FIRRMA) (Title XVII, P.L. 115-232), which 'strengthens and modernizes' the national security review of foreign direct investment (FDI) transactions by the Committee on Foreign Investment in the United States (CFIUS) (under P.L. 110-49). CFIUS is an interagency body comprising nine Cabinet members and others as appointed. The draft regulations initiate provisions that would affect how certain real estate and noncontrolling investments will be scrutinized. These regulations were widely anticipated by various stakeholders for clarifying key aspects of FIRRMA."
