Direct holdings in the ownership graph

Direct holdings in the ownership graph — Two blocked direct owners. Percent ownership; effective date fixed for this case. Exact values are in the figure data below.
Percent ownership; effective date fixed for this case

The directed edges are documented ownership interests in this synthetic U.S. OFAC example. Owners X and Y are assumed blocked. The graph contains no cross-holdings, trusts, nominee arrangements, or conflicting share classes; those would require additional analysis.

A customer’s intermediate parent has two assumed blocked owners. Their separate interests must be evaluated together under the stated ownership rule.

Separate below-50-percent holdings are assessed independently.

All amounts, rates, capacity limits, and outcomes in this case are synthetic. The three conditions are separate assumptions for comparison. A better result in the response condition is not measured proof that the proposed control causes that improvement. The figures expose the calculation and its limits; a real deployment needs its own evidence.

Read the result

Assumed blocked owners hold 30% and 25% of Intermediate A. Their aggregate is 55%. A then owns 60% of Customer B. The worked determination is: Blocked under the illustrated ownership rule. The simple economic product of 33.00% is retained only to show why multiplication and rule-specific status propagation are different operations.

Aggregate the relevant direct interests

Percent; totals 100

Assumed blocked owners X and Y hold 30% and 25% of Intermediate A, for 55% in aggregate. Other interests total 45%. The chart counts each direct holding once and uses one common ownership basis.

An adjacency matrix preserves edge meaning

An adjacency matrix preserves edge meaning — Two blocked direct owners. Percent; columns total 100. Exact values are in the figure data below.
Percent; columns total 100

Rows identify owners and columns identify entities. Each nonzero cell is one direct interest from the graph. A matrix can help detect duplicated edges and inconsistent totals, but it cannot resolve a missing or unreliable ownership fact.

Status propagates through qualifying entities

Status propagates through qualifying entities — Two blocked direct owners. Simplified application of the stated ownership rule. Exact values are in the figure data below.
Simplified application of the stated ownership rule

Intermediate A has 55% aggregate ownership by assumed blocked persons. In the known-data calculation, its status is blocked. Its 60% holding in Customer B is then evaluated in that capacity. Incomplete evidence prevents a final conclusion.

Economic multiplication is a different calculation

Economic multiplication is a different calculation — Two blocked direct owners. Percent and legal-status concepts kept separate. Exact values are in the figure data below.
Percent and legal-status concepts kept separate

A simple product gives 33.00% economic look-through interest. That number does not replace OFAC status propagation through an entity that is itself blocked under the 50 Percent Rule. The rule-specific analysis must retain both the graph and the intermediate determinations.

The ownership threshold is a discontinuity

The ownership threshold is a discontinuity — Two blocked direct owners. Percent; 0/100 indicator is not a risk probability. Exact values are in the figure data below.
Percent; 0/100 indicator is not a risk probability

The plot varies owner Y’s stake while holding X at 30%. The status indicator changes when their aggregate reaches 50%. An indicator of 100 means the stated test is met; it is not a probability or a severity score. Other restrictions can still apply below that point. Horizontal positions are the labeled observations or scenarios; equal spacing does not imply equal numerical increments.

An ownership result is only as defensible as its inputs. Keep the document, effective date, retrieval date, ownership basis, and reviewer attached to the edge. A recent download of an old filing does not make the underlying ownership current.

If X’s 30% edge appears twice in a data feed, naive addition produces 85% instead of the supported 55%. Deduplicate by the underlying ownership fact and effective interval, not merely by a convenient text label.

Control and ownership are separate relationships

Control and ownership are separate relationships — Two blocked direct owners. Typed relationships; only ownership enters this percentage calculation. Exact values are in the figure data below.

The management edge is deliberately different from an ownership edge. Control by a blocked person can raise separate concerns, but it should not be silently converted into a percentage within this ownership formula. The appropriate legal review considers the actual program and facts.

The current determination is: Blocked under the illustrated ownership rule. A screening engine should be able to return unresolved evidence without forcing a false clear or a false exact percentage. Operational handling must follow the institution’s approved procedure and applicable obligations.

A prior ownership review is a dated conclusion. New filings, a transfer of shares, a list update, or a correction to entity identity can change the relevant facts. The event log should preserve the old conclusion while recording the basis for the new one.

Connect the result to the system

Aggregate relevant supported interests once, using the same ownership basis and effective date.

Check the population, evidence, permitted action, and actual effect together. A balanced calculation can still use the wrong population; a successful response can still leave an unknown financial outcome. The case’s numerical result applies only to its stated assumptions.
