Meaning and transaction use
The FTC states that the HSR programme gives the FTC and DOJ information about large mergers and acquisitions before they occur and that parties may not close until the applicable waiting-period condition is met. [S1]
The FTC's HSR rules describe premerger notification, reporting and waiting-period requirements and were updated in February 2025. [S2]
A global clearance plan may also include sector, foreign-investment, licensing, ownership, national-security or other approvals. The applicable perimeter requires transaction-specific legal analysis.
Worked example
Illustrative clearance tracker only. Assume eight required workstreams: five complete, two filed and pending, and one not yet filed.
Scroll the table horizontally to view all columns.
| Measure | Calculation | Result |
|---|---|---|
| Complete | 5 / 8 | 62.5% |
| Filed and pending | 2 / 8 | 25.0% |
| Not filed | 1 / 8 | 12.5% |
| Filed or complete | (5 + 2) / 8 | 87.5% |
Seven workstreams have been filed or completed. The transaction remains subject to the legal status and closing conditions for every required clearance.

Verify closing readiness
Confirm that each regulatory closing condition is satisfied, waived where permitted or otherwise addressed.
Evidence checklist
Perimeter evidence
Structure chart, revenue and asset data, activities, licences, ownership and jurisdiction analysis.

Decision framework
| Situation | Proposed action |
|---|---|
| A threshold is uncertain | Obtain jurisdiction-specific advice and document the factual inputs and legal conclusion. |
| A review may exceed the long-stop date | Model timetable options and apply the agreement's extension and termination provisions. |
| A regulator requests a remedy | Assess operational, value and execution effects before agreeing terms. |
| Closing teams receive conflicting status reports | Use the official evidence register and designated legal sign-off. |
Common errors to check
- Treating signing as authority to close.
- Checking only merger-control filings while ignoring sector or investment approvals.
- Using stale thresholds or filing requirements.
- Reporting a filing acknowledgement as final clearance.
Build the clearance critical path
Bring the transaction structure, jurisdiction map, approval matrix and draft timetable to a clearance-planning review. Identify dependencies, evidence owners and closing-critical dates.
