Multi-layer ownership structures in UBO determination
Multi-layer ownership is where informal spreadsheets fail. Ultimate Beneficial Owner (UBO) determination through holdings requires layer-wise assessment, clear evidence per edge, and disciplined handling of accumulation — not multiplying every percentage down the chain as a default shortcut.

Assess each layer
For each legal entity in the chain, capture owners/controllers and apply ownership-interest and control tests appropriate to that entity. Only then reason about how control or ownership transmits to the target entity.
Why naive chain multiplication misleads
Multiplying 40% × 40% = 16% can understate control when intermediate entities are controlled outright, or misstate economic reality when voting and capital diverge. Treat accumulation rules as legal tests with conditions — see the AMLR accumulation-method cluster — not as a spreadsheet habit.
Tooling requirements
Software should preserve the graph, the per-layer conclusions, and the special-case notes. Transparify is built as a guided workflow with confirmation — not as an autonomous UBO engine.
