Scenario result

Malaysia: a 100% disruption directly affects 1 facility, with 0 documented downstream facilities exposed.

Dataset sandbox-2026.09.17-manufacturers. Values with missing route or ownership shares remain unquantified. Results cover documented facilities, not the whole market. Annual output records may cover different fiscal periods; they are not current run rates.

Who is affected, and why?

Direct targets and downstream facilities linked by documented routes.

Commercial commitments to review

Potential obligations and procurement exposure, separate from quantified physical loss.

4

Company-level commitments cannot identify a receiving factory or the share of its inputs. These records guide investigation; they do not increase the calculated production loss.

Each stage is measured against its own baseline. Bars compare percentage impact, not quantities across different products. Missing operating output is unquantified.

Operating alternatives

Facilities with product fit, spare capacity, and a shared documented customer.

Operating
No qualifying operating alternative is documented.

Relevant project pipeline

Non operating projects in affected product stages.

How to read this result

Coverage limits and calculation rules.

Evidence based
The result uses disclosed operating capacity and documented relationships only.
  • Operating output uses reported annual production where available, otherwise capacity multiplied by disclosed utilisation. Undisclosed utilisation is not estimated.
  • Annual production records can cover different fiscal periods. This is a sensitivity analysis of documented output, not a current run-rate forecast.
  • No documented downstream exposure does not mean no customers or no real-world impact. Missing supply relationships remain outside the model.
  • Disclosed route shares are additive and capped at the destination facility's operating output.
  • Replacement capacity is allocated once within each stage and only where a shared customer is documented.
  • Replacement allocation is conservative, prioritising facilities with fewer documented alternatives. It is not an optimised routing plan.
  • Construction and development projects are not counted as current replacement capacity.
