U.S. Department of the Treasury

Given the specificity of certain provisions of the rule, Treasury anticipates that it will periodically review, and when necessary amend, the regulations to address changes in technology and data use, as well as the evolving national security landscape more generally.

The Department of the Treasury published proposed versions of the regulations in September 2019 and received comments from the public.  Treasury made a number of revisions in response to the comments submitted during the comment period.  The preambles to the final rules summarize these changes.

In response to written comments, the final rules update a number of provisions including by:

• adding a definition for “principal place of business;”
• modifying certain criteria to qualify as an “excepted investor;”
• clarifying the application of the “incremental acquisition rule;”
• adjusting the treatment of genetic data within the definition of “sensitive personal data;”
• refining the application to investment funds, including by amending the definition of “substantial interest;”
• modifying the exceptions for certain real estate transactions in airports and maritime ports; and
• refining the geographic coverage relating to certain military installations on appendix A to the real estate regulations.

The rules also include a number of additional illustrative examples and provide clarifying edits in the text of the provisions.  Finally, the rule amending the part 800 regulations incorporates many of the provisions of the pilot program regarding critical technologies (published in October 2018), including the mandatory declaration requirement for certain covered transactions involving certain U.S. businesses that produce, design, test, manufacture, fabricate, or develop one or more critical technologies.  The mandatory declaration requirement for certain critical technology related transactions was further revised by regulations effective October 15, 2020.

The specificity provided in the regulations gives clarity to the business and investment communities with respect to the types of transactions that are covered by the Committee’s new authority under FIRRMA.  The CFIUS process, as modernized and strengthened by FIRRMA and these regulations, should enhance confidence in the nation’s longstanding open investment policy.

Final regulations implementing FIRRMA took effect on February 13, 2020.  Regulations implementing a CFIUS filing fee took effect on May 1, 2020.  A revision to the regulations concerning mandatory declarations was made effective October 15, 2020.  Additional information on CFIUS’s legal authorities and regulations can be found on the CFIUS Laws and Guidance page.

The rules published in the Federal Register in 2020 finalize the regulations relating to FIRRMA.  The Department of the Treasury previously published proposed versions of the regulations, on which it received comments from the public.  The regulations implement changes that FIRRMA made to CFIUS’s jurisdiction and review process.  For more information on the implementing regulations, refer to the CFIUS Laws and Guidance page.
