Professional Guide to CFIUS Filing Calendars & Statutory Timelines
The Committee on Foreign Investment in the United States (CFIUS) is an interagency committee authorized to review certain foreign investments in U.S. businesses and real estate to determine their potential impact on national security. Under the Foreign Investment Risk Review Modernization Act (FIRRMA), CFIUS operates within highly rigid, strict, and statutory timelines. Successfully planning around these deadlines is critical for cross-border mergers and acquisitions, venture capital financings, and corporate governance actions.
1. Understanding the Time Computation Rules (31 C.F.R. § 800.104)
Under CFIUS regulations (specifically 31 C.F.R. § 800.104 for standard corporate transactions and 31 C.F.R. § 802.104 for real estate transactions), the day-counting process follows precise statutory guidelines:
- The Day 1 Principle: In computing any statutory period of time, the day of the triggering event (e.g., formal notice acceptance by the Committee) is not included. The first calendar day of the review period is the calendar day after acceptance, designated as Day 1.
- Calendar Days vs. Business Days: Standard CFIUS assessment, review, and investigation periods are counted in calendar days (including weekends and holidays). Only the optional Draft Notice feedback follows a strict 10-business-day target.
- Weekend and Holiday Shifting: If the final day of a statutory review, investigation, or presidential period falls on a Saturday, Sunday, or a legal Federal holiday, the deadline is extended to the end of the next day that is not a weekend or holiday. This ensures the parties and the government are not forced to file or act on days when federal offices are closed.
2. Short-Form Declarations vs. Long-Form Notices
FIRRMA introduced a bifurcated system designed to expedite reviews of low-risk transactions while maintaining thorough scrutiny for complex filings.
Short-Form Declarations (30 Days)
Declarations are abbreviated, low-cost filings that must be reviewed and assessed within 30 calendar days. At the end of the 30-day period, the Committee must take one of four actions: (1) clear the transaction (granting safe harbor), (2) request that the parties file a full notice, (3) notify the parties that CFIUS is unable to complete action based on the declaration (often referred to as a "shrug-off" letter, where safe harbor is not granted), or (4) initiate a unilateral review of the transaction.
Long-Form Notices (Up to 105+ Days)
Long-form notices are detailed filings that undergo a multi-phase review. They begin with an optional but recommended Draft Notice, which provides CFIUS with a 10-business-day window to offer pre-filing comments. Once a formal notice is accepted, the timeline progresses sequentially through a 45-day Phase I Review, followed by an optional 45-day Phase II Investigation (which can be extended by 15 days in "extraordinary circumstances"). If unresolved national security issues remain, the notice is referred to the President for a 15-day Phase III Decision.
3. Best Practices for M&A Deal Planning
To minimize execution risk, deal makers should follow these tactical guidelines:
- Always File Draft Notices: Filing a draft notice allows CFIUS staff to review the structure and request additional disclosures informally. This prevents the Committee from rejecting a formal notice for administrative completeness, which would reset the statutory clock.
- Incorporate Mitigation Negotiation Time:If your transaction involves sensitive "TID U.S. businesses" (Technology, Infrastructure, or Data), expect the review to enter Phase II. Mitigation agreement negotiations often consume the entire 45-day investigation window and may require requesting the 15-day extraordinary extension.
- Synchronize with HSR and SEC Filings:Coordinate the CFIUS roadmap with Hart-Scott-Rodino (HSR) antitrust waiting periods and SEC Schedule 14D-9 or proxy notice timelines. The CFIUS clearing target should be integrated into the transaction agreement's "drop-dead" or end date provisions with a buffer for holiday-shifting rollovers.
