“Prior to February 13, 2020, the regulations at 31 C.F.R. part 800 focused on transactions that could result in foreign control of any U.S. business. Effective February 13, 2020, the regulations at 31 C.F.R. part 800 implement changes that FIRRMA made to CFIUS’s jurisdiction and process, including with respect to certain non-controlling “covered investments” that afford a foreign person certain access, rights, or involvement in certain types of U.S. businesses.”
