Investment screening

Test ownership, control, sector, technology, data, location and jurisdiction facts early enough to manage filing and national-security risk.

Quick answer

Investment screening is governmental review of specified investments or acquisitions under foreign-investment, outbound-investment or national-security regimes. The scope and filing route depend on current law and transaction facts such as investor identity, control, sector, technology, data, assets and location.

Use the worked example

Meaning and transaction use

Treasury guidance describes CFIUS authority to review covered transactions involving foreign-person control of a United States business. [S1]

Treasury's 2024 CFIUS report states that declarations are mandatory for certain covered transactions involving specified substantial interests. [S2]

Proposed control method: maintain a jurisdiction matrix with factual inputs, advice, filing route, timing, conditions and closing evidence.

Worked example

Illustrative screening matrix only. Assume six jurisdictions require assessment: three complete, two under legal review and one awaiting ownership data.

Scroll the table horizontally to view all columns.

Measure	Calculation	Result
Complete	3 / 6	50.0%
Under legal review	2 / 6	33.3%
Awaiting data	1 / 6	16.7%
In progress or complete	(3 + 2) / 6	83.3%

Five assessments are active or complete; one remains blocked by missing ownership data.
