MetricGovernance body composition and oversight

Highest-governance-body member tenure profile

Measurement answer

What this metric measures

Member-level service and tenure record for the named highest governance body at a declared reference date, preserving appointment, current-term, interruption, reappointment and person-versus-seat rules instead of publishing an unsupported generic average.

Reporting boundary

First appointment, continuous service, cumulative service and current term are separate clocks. Simultaneous board and committee memberships do not create multiple years of personal service in a person-level view.

Library mappings and variants

These links compare quantity, population, boundary, period, unit, denominator, aggregation, dimensions, and method edition. Partial relationships are navigation aids only and never authorize observation reuse.

No single formula

Populate the structured fields from qualifying source observations and retain each field-level unit, boundary, status, and method; do not collapse the disclosure into one calculated value.

Verified sources

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.

Interpretation boundaries

Method disclosures required

Source-edition basis: GRI 2: General Disclosures 2021 — 2021 edition, effective for reports published from 1 January 2023; UK Corporate Governance Code 2024 — 2024 Code, effective for accounting periods beginning on or after 1 January 2025. Retain the exact source edition on every observation; later editions require a separate method profile.

  • Reporting entity.
  • Highest governance body and system.
  • Member identifier or required pseudonym.
  • Person or membership unit.
  • Seat or role and executive status.
  • First appointment and current-term start.
  • Prior service segments.
  • Interruption and reappointment treatment.
  • Retain the exact measurement-source edition with every observation.
  • A source-reported tenure duration retains its start event, reference date, elapsed-time convention, service segments, interruption treatment and person-or-membership basis.

Record-specific limitations

  • Tenure is not experience, independence, performance, contribution or entrenchment.
  • Appointment, interruption and reappointment rules vary.
  • The sources do not define a universal arithmetic average.

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.
