Reporting boundary

All employees in the stated reporting boundary, using gross hourly pay over the same reporting period and a consistent pay perimeter; category, country or segment results are separate recomputations rather than additive parts of the overall result.

Evidence and status sources

Sustopedia checked each record-specific claim directly against primary publisher material. Labels distinguish current measurement authority from future compatibility and corroborative, legal, edition, or method status context. Corroborative evidence can support a stated limitation but cannot establish the core measurement by itself.

  • Gross-hourly-pay components and currency treatment
  • Zero-comparator, reporting-category, and privacy-suppression rules

Record-specific limitations

  • Jurisdiction-specific rules can change the employee population, pay components, reference period, and reporting categories.
  • The method must define behavior when the male-pay comparator is zero or unavailable and must avoid unsupported cross-currency aggregation.
  • An unadjusted gap is not evidence of unequal-pay liability, does not control for role or tenure, and requires privacy-aware suppression for small cohorts.

Interpret this metric with the stated reporting boundary, period convention, value shape, and unit. Results prepared with different boundaries or conventions may not be directly comparable.

Measurement evidence supports the core record-specific claims described above. Corroborative evidence can support limitations, while compatibility and status sources provide their separately labelled context. None of these cards by itself determines an organisation's legal applicability, filing readiness, assurance status, or compliance conclusion.
