On July 23, 2024, the Committee on Foreign Investment in the United States (“CFIUS“) released its 2023 Annual Report to Congress. The Annual Report provides data on transactions filed with CFIUS in 2023, the third full calendar year following the introduction of the implementing regulations for the Foreign Investment Risk Review Modernization Act of 2018 (“FIRRMA“). Consistent with decreased global merger and acquisition activity in 2023, CFIUS received fewer notices and declarations of covered transactions or covered real estate transactions than in the previous year. However, its overall efficiency improved in several respects, which included (i) an increased clearance rate for transactions that did not require mitigation measures, (ii) a reduced “withdraw and refile” rate, and (iii) an increased rate of concluded action regarding declarations.
Below, we have summarized the key takeaways from the Annual Report:
- Fewer filings and increased clearance rate. In 2023, CFIUS assessed 109 declarations and reviewed 233 notices of covered transactions. This is a 23% decrease from the 440 transactions CFIUS reviewed in 2022. CFIUS cleared 66% of transactions that did not require mitigation measures within either the 30-day assessment period for declarations or the initial 45-day review period for notices. This is an 8% increase in the clearance rate from 2022.
- Investors from China and US-allied countries submitted the most declarations and notices. From 2021-2023, investors from Canada (13%), Japan (9%), Germany (7%), and South Korea (7%) accounted for the largest proportions of declarations, whereas investors from China (13.5%), Singapore (8.4%), Canada (8.1%), Japan (6.5%), and the United Kingdom (6.5%) accounted for the largest proportions of notices.
- More than half of all notices proceeded into investigation.  In 2023, there were 128 notices that proceeded to investigation. This is approximately 55% of notices, which is slightly less than 2022 (57%). The number of notices that were withdrawn after the commencement of an investigation decreased from 24% to 18% of notices relative to 2022. This is the first reduction in five years.
- Fewer withdrawn notices and one filed agency notice. CFIUS approved the withdrawal of 57 notices after the commencement of the investigation period compared to 87 withdrawn notices in the previous year. In most instances, the notices were withdrawn after CFIUS informed the parties that the transaction posed a national security risk to allow the parties additional time to consider CFIUS’ mitigation terms. In 43 of 57 instances, the parties filed a new notice in either 2023 (i.e., 34 notices refiled) or 2024 (i.e., 8 notices refiled). Treasury filed an agency notice in one instance after parties declined to refile a rejected notice.
- Increased monitoring of compliance with mitigation agreements. The CFIUS Monitoring Agencies conducted 43 site visits in 2023, which involved interviews with senior executives and personnel, records checks, physical security assessments, and other activities intended to assess compliance in mitigation agreements. CFIUS assessed or imposed four civil monetary penalties for breaches of material provisions of mitigation agreements, which is nearly double the number of civil monetary penalties that CFIUS has issued during its nearly 50-year history, and the first under the regulations implementing FIRRMA. A list of CFIUS enforcement actions that imposed penalties are available on its website here.
- Enforcement of compliance with mandatory filing requirements. CFIUS commenced several investigations to ensure compliance with its mandatory filing requirements, some of which resulted in issuing formal determinations of noncompliance.  These determinations did not result in penalties after CFIUS considered the specific facts and circumstances. Nonetheless, these matters of noncompliance led CFIUS to issue clarifying guidance on how it considers a transaction’s “completion date” for purposes of assessing when a mandatory filing should be submitted, where the foreign person first acquires equity interest but will not receive control or covered investment rights until after CFIUS’ review. Our prior blog post on CFIUS’ May 2023 “completion date” FAQ is available here. In addition, CFIUS received its first voluntary self-disclosure for a potential failure to file a mandatory declaration.
- Some transactions cleared before the 45-day review or 90-day investigation. On average, CFIUS closed reviews in 45.8 calendar days and closed investigations in 85.8 calendar days. This reflects a continued decrease in the average days to close reviews and increase in the average days to close investigations over the past two years. The mean calendar days for 2023 are 45.0 and 91.0 for reviews and investigations, respectively. The Annual Report notes that these numbers may exceed the 45 or 90 calendar days required in the CFIUS regulations because, in certain cases, the 45th or 90th calendar days may fall on a weekend or public holiday. In those cases, the next business day is considered the final day of the review or investigation based on the CFIUS regulations.
