Screen the acquisition structure as well as the name

A seller receives a bid from a newly formed acquisition company whose name does not appear on a sanctions search. That result answers only the name question. It does not establish who owns the company, whether an owner is blocked, or whether another participant in the transaction creates a sanctions issue. Request the ownership structure while the parties can still address a problem without disrupting an imminent closing.

OFAC’s published 50 Percent Rule guidance explains that entities directly or indirectly owned at least 50% in the aggregate by one or more blocked persons are considered blocked. Its indirect ownership examples use ownership through entities that themselves meet the blocked ownership threshold. The analysis therefore cannot stop with the immediate shareholder register or a simple multiplication of every percentage in a corporate chain.

Treat the acquisition company, material owners, signing representatives, payment participants, and relevant transaction jurisdictions as parts of the diligence file. Define the scope with sanctions counsel from the actual facts. A domestic mailing address, familiar bank, or financing commitment does not independently establish that all participants and activities are permitted.

Work through ownership rather than intuition

Assume a hypothetical acquisition company has three direct owners. One blocked person holds 28%, another blocked person holds 24%, and an unrelated unblocked investor holds 48%. The blocked interests aggregate to 52%. A search limited to the acquisition company’s own name could miss the ownership issue entirely. Having no single majority shareholder does not solve the aggregation problem.

Now consider a different hypothetical: a blocked person owns 60% of Holding Company H, and H owns 55% of Acquisition Company A. Multiplying 60% by 55% gives 33%, but that arithmetic alone is not the method illustrated in OFAC’s indirect ownership guidance. H is itself blocked by its ownership, and its 55% stake matters when assessing A. The diligence team should document the rule applied at each level rather than recording only the final multiplication.

These examples concern the ownership rule, not an exhaustive sanctions clearance. Under OFAC FAQ 398, control without the requisite ownership does not automatically block an entity under this particular rule. OFAC nevertheless cautions about significant minority interests, control, and dealings involving a blocked representative. Other program-specific restrictions can apply independently.

Put the finding into the deal timetable

Ask for a dated organization chart, ownership percentages, entity names, identifying information, and the supporting register or equivalent records. Identify intermediate entities rather than accepting a diagram that groups them into a single investment fund box. Clarify what changed between signing and closing, including new investors, transfers, and financing arrangements.

Assign the review early enough to determine whether a license or other authorization is relevant and whether the transaction can proceed in its proposed form. Do not assume that a representation in the purchase agreement authorizes an otherwise prohibited transaction. Equally, do not invent a workaround by changing the name of a buyer, removing a signature, or routing payment through a different bank while beneficial ownership remains unresolved.

The seller’s cash forecast should include a genuine hold scenario. If a hypothetical closing delayed for six weeks requires $42,000 of monthly operating support, the additional need is approximately $63,000 before other timing effects. That number helps establish a liquidity contingency; it does not justify proceeding with a transaction that has not received the required determination. Keep financing expiration and regulatory conditions visible in the same calendar.

Preserve a reviewable decision and refresh it

Retain the ownership evidence, dated search results, reviewer conclusions, questions resolved, and any applicable authorization documents. A search screenshot without the underlying ownership chart will not explain why an unlisted company was treated as acceptable or problematic. Record the relevant rule and its application to the facts so that another reviewer can understand the decision.

Refresh the review at the agreed transaction checkpoints. A new investor entering the buyer before closing can change the ownership analysis even though the acquisition company’s name stays the same. The seller should have a process for receiving updated information rather than relying on a certification prepared months earlier for another bid.

Sanctions programs, designations, and authorizations can change. The examples here illustrate OFAC’s ownership guidance available for this article; they are not a clearance of a named buyer or a promise that a transaction below a percentage threshold is lawful. Resolve program-specific questions, blocked property handling, reporting, and payment instructions with the relevant professionals before acting. The useful deliverable is a documented determination for the actual transaction and date, supported by a structure that has been checked through its relevant levels.
