A technology distributor operating across North America, Europe, and South-East Asia ran routine counterparty screening before signing a mid-sized reseller agreement. The primary counterparty returned clean. A second-tier check on that counterparty's shareholders surfaced a name that matched, on a fuzzy-logic search, a person on OFAC's SDN List (OFAC's list of Specially Designated Nationals and blocked persons). The compliance team paused. Was the match a true hit? If so, did the 50 percent rule (OFAC's rule treating entities owned 50 percent or more in the aggregate by blocked persons as themselves blocked) reach the counterparty? And what did the firm owe to OFAC before it could move forward?
As of mid-2026, the 50 percent rule remains the decisive threshold in US sanctions ownership analysis. Where blocked persons own 50 percent or more of an entity in the aggregate – directly or through intermediate layers – OFAC treats that entity as blocked regardless of whether it appears on the SDN List by name. A false or incomplete ownership assessment at this stage can convert a lawful trade relationship into an unlicensed transaction with a blocked person, carrying significant civil and criminal exposure.
This case comment walks through an anonymised matter our practice handled: the situation that triggered the review, the legal question at its centre, the ownership analysis we conducted across US, UK, and EU regimes, the options the client faced, and the lessons that apply to any business relying on multi-layer counterparty screening.
The situation: a screening hit, an uncertain ownership chain, and a stalled transaction
The screening match arose from a parent company incorporated in a third-country jurisdiction with limited public-registry disclosure. The distributor's existing screening programme checked against the SDN List at the entity and individual level, but it mapped ownership only one corporate layer deep. The potential match sat two layers above the counterparty – a natural person listed on the SDN List holding a reported interest in an intermediate holding company, which in turn held shares in the direct counterparty.
Three immediate questions arose. First, was the person on the SDN List the same individual as the shareholder in the intermediate company – a name-matching question requiring disambiguation. Second, if the match was confirmed, what percentage did that person hold in the intermediate company, and what did that company hold in the direct counterparty? Third, could the aggregate ownership calculation reach or exceed 50 percent, triggering the rule?
The distributor's in-house compliance team had the right instinct – they paused the transaction. But they were uncertain whether they were obliged to report the potential blocked-property identification to OFAC, whether the transaction could proceed under a general licence (a standing authorisation that permits a defined category of transactions without a separate application), and whether the UK and EU positions on the same ownership chain would differ materially. We were instructed to advise on all three questions.
What is the OFAC ownership test, and why does it differ from the UK and EU approach?
Under OFAC's guidance derived from IEEPA, the 50 percent rule is mechanical: aggregate the ownership interests of all SDN-listed persons in a given entity, directly and indirectly, and if the total reaches or exceeds 50 percent, the entity is blocked. Intention, day-to-day management, and the degree of practical control exercised by the listed person are legally irrelevant to the threshold test. The rule is binary.
The UK and EU positions are structurally different. Under OFSI's approach – which derives from SAMLA and the relevant thematic regulations – an entity is caught not only through ownership at or above the relevant threshold but also through ownership and control (the UK and EU test for whether a non-listed entity is caught through a listed person). Control can be established even where a listed person holds less than 50 percent, provided that person can direct or veto decisions. The EU Council regulations adopt a broadly parallel test, covering entities owned or controlled by a designated person.
Why does the divergence matter? Because a cross-border distributor like our client faced a situation in which the same ownership chain might be treated as caught under one regime and borderline under another. A business that clears the OFAC threshold test but fails to consider UK and EU ownership and control analysis may find itself in breach of a separate regime to which it is also subject. In our experience, firms relying on a single-regime ownership model systematically undercount their exposure when they have EU-nexus operations or UK-incorporated entities in the same group.
The position above covers the standard case. Your facts – the percentage holdings at each layer, the jurisdictions involved, the nature of the goods or services, and the specific SDN programme in play – change the analysis.

How the ownership analysis was conducted: method and data sources
A sound ownership analysis under the 50 percent rule follows a structured sequence, not a single database search. We began by confirming the identity of the potential match through multiple data points – date of birth, nationality, known business interests, and transliteration variants of the name. Name-match alerts are a starting point, not a conclusion. A confirmed or probable match on identity is a precondition for the rest of the analysis; an unresolved identity question is itself a risk that must be escalated, not quietly closed.
Once identity was confirmed as probable (the evidence was strong but not conclusive on one data point), we turned to the ownership chain. The intermediate holding company's register filings in its home jurisdiction showed the listed person as a direct holder of a substantial interest. The exact percentage was not publicly disclosed in the filings available to us, which is a common feature of corporate registers in certain jurisdictions. We supplemented public-registry data with commercial beneficial-ownership databases and, where available, regulatory filings in other markets where the intermediate company had reported interests.
The analysis produced a range: under a conservative reading of the disclosed data, the listed person's aggregate indirect ownership of the direct counterparty was below 50 percent. Under a broader reading – crediting partial or estimated interests in the intermediate layer – it could reach the threshold. OFAC's guidance is clear that a business cannot simply assume the lower end of an ownership range is correct when credible evidence supports a higher figure. The firm faced what practitioners call an "uncertain ownership" situation – and that uncertainty is itself a compliance event requiring a documented response.
We also assessed whether any other SDN-listed person held an interest in the same chain, because the 50 percent rule aggregates across all listed persons. None was identified. But the exercise illustrated a point we make repeatedly to clients: the rule is not tested entity-by-entity in isolation; it is tested across the full population of listed shareholders in the ownership tree.
What options did the client face?
With an uncertain ownership result, the distributor had four realistic options. First, it could seek additional evidence to resolve the range – approaching the counterparty for certified ownership disclosures, seeking a legal opinion from local counsel in the relevant jurisdiction, or commissioning an enhanced due-diligence report. This was the least disruptive path but carried the risk that the counterparty would become aware of the review and that any disclosure obtained could be incomplete or unreliable.
Second, the distributor could apply for a specific licence (a case-by-case authorisation to conduct an otherwise prohibited transaction) from OFAC. A specific licence application signals to OFAC that the applicant has identified a potential issue and is seeking lawful cover. It does not constitute an admission of violation, and OFAC's published guidance acknowledges that applicants may seek licences in uncertain situations. The timeline for a specific licence decision is not guaranteed and can extend well beyond the commercial window for the transaction.
Third, the distributor could walk away from the transaction. Where the ownership uncertainty cannot be resolved and no general licence covers the activity, declining to proceed is always a permissible – and sometimes the only defensible – outcome. This is commercially costly, but it avoids the risk of proceeding with a potentially blocked counterparty.
Fourth – and this was the option the client found most commercially attractive – the distributor could seek a written representation from the counterparty itself, combined with a contractual warranty on ownership structure, while simultaneously escalating the matter internally and documenting the analysis. This approach does not eliminate legal risk; OFAC will not necessarily treat a false representation by a counterparty as a complete defence to liability. But a well-documented, good-faith review with appropriate representations is relevant to OFAC's penalty analysis, particularly when assessing whether conduct was wilful.
If a transaction has already been flagged, or a filing is under review, an early assessment preserves options that narrow with time. Reach our team at info@caldervance.com to discuss the position before it hardens.
Risk flags that should have triggered an earlier review
Looking back at the distributor's screening programme, several risk indicators were present that, individually or together, should have triggered a deeper ownership inquiry before the contract reached the signing stage. Identifying these flags is more useful than cataloguing what went wrong after the fact.
The first flag was geography. The counterparty's ultimate beneficial owner was reported to be domiciled in a jurisdiction that multiple sanctions regimes treat as higher-risk. Screening programmes calibrated to the SDN List alone, without country-risk weighting in the ownership search, will systematically miss this context.
The second flag was ownership opacity. The intermediate holding company's corporate register disclosed shareholders only at a summary level, without percentage breakdowns. Where a corporate register does not disclose percentages, that gap is itself a material data point. Programmes that mark "ownership unknown" as a neutral result, rather than as a risk requiring escalation, will undercount exposure across an entire class of counterparties.
The third flag was the structure of the screening tool. The distributor's tool searched entity names and first-tier individual shareholders. It did not follow indirect ownership chains beyond one layer. OFAC's 50 percent rule explicitly captures indirect ownership through chains of any length. A one-layer search is structurally insufficient for any counterparty with a complex or multi-jurisdictional ownership structure.
The fourth flag was the nature of the goods. The distributor's products had dual-use characteristics and were subject to US Export Administration Regulations. A counterparty that triggers ownership concern under OFAC is also a counterparty that warrants review under BIS – the same ownership chain may support an Entity List nexus or a red-flag indicator under the EAR's general prohibition on proceeding where red flags are present. Ownership and export-control analysis are not separate workstreams; they are parallel obligations that share a common evidence base.
The route taken and the outcome
After reviewing the options, the distributor instructed us to pursue option one – additional evidence – in parallel with preparing a specific licence application as a contingency. We drafted a structured ownership-disclosure request to the counterparty's legal advisers, covering beneficial ownership to the ultimate natural person level, the percentage interests at each intermediate layer, and a representation as to the absence of other SDN-listed interests. We also engaged local counsel in the relevant jurisdiction to obtain a legal opinion on the completeness of the disclosed register data.
The counterparty's response confirmed that the SDN-listed individual held a minority interest below the 50 percent threshold in the intermediate holding company. The certified ownership schedule showed aggregate indirect ownership of the direct counterparty at a level that did not reach the threshold under the 50 percent rule. The identity question – the remaining ambiguity – was resolved by the counterparty's legal advisers producing documentation that distinguished the listed person from the shareholder on the register. The names were similar but referred to different individuals.
The specific licence application was not submitted. The transaction was cleared to proceed, subject to enhanced ongoing monitoring of the counterparty's ownership structure and a contractual right to re-screen and terminate on reasonable notice if the position changed. The distributor also restructured its screening programme: it introduced multi-layer indirect ownership search protocols, escalation procedures for ownership opacity, and a formal linkage between OFAC and EAR review at the counterparty-onboarding stage.
The outcome was commercially positive. It is not a template. In another matter with the same initial indicators, the evidence could have gone the other way – and the programme redesign, not the transaction result, is the durable lesson.
The common myth: ownership at one remove is always safe
The most persistent misconception we encounter in ownership and control assessments is that a counterparty is safe to transact with if it is not itself on the SDN List, provided no SDN-listed person appears as a direct shareholder. This is incorrect, and it is a misconception that creates serious exposure for compliance teams that have not stress-tested their screening logic against the 50 percent rule's indirect-ownership chain.
OFAC's position is clear. An entity that an SDN-listed person does not directly own can still be blocked if that person owns it indirectly through one or more intermediate entities – and if the aggregate indirect interest reaches 50 percent. There is no "one degree of separation" exemption. The only relevant question is the aggregate ownership percentage across all SDN-listed persons at every layer. A compliance programme that does not follow the chain to its end has not completed the test.
A related misconception is that OFSI and the EU apply the same test. They do not. Under the UK and EU regimes, control – not just ownership – is a separate and independent ground for capture. A counterparty in which an SDN-listed person (or its EU/UK equivalent) holds a minority stake but exercises effective control over management decisions may be caught under UK and EU rules even though the 50 percent ownership threshold is not met. For businesses operating across all three regimes, the UK and EU control analysis must be run alongside the OFAC ownership test, not instead of it.
