This rule sets forth the scope of, and procedures for, a pilot program of the Committee on Foreign Investment in the United States (CFIUS, or the Committee) under section 721 of the Defense Production Act of 1950, as amended by the Foreign Investment Risk Review Modernization Act of 2018 (FIRRMA).  Pursuant to section 1727(c) of FIRRMA, this pilot program implements the authorities provided in two sections of FIRRMA that did not take effect upon the statute’s enactment.  First, the pilot program expands the scope of transactions subject to review by CFIUS to include certain investments involving foreign persons and critical technologies.  Second, the pilot program makes effective FIRRMA’s mandatory declarations provision for all transactions that fall within the specific scope of the pilot program.  The pilot program implemented through these regulations will end no later than the date on which the full regulations implementing FIRRMA become effective, and in no event later than the date that is 570 days after the enactment of FIRRMA. These regulations will be amended, replaced, or removed no later than the date on which the pilot program ends.
