To prepare this disclosure
Disclosure focus

This disclosure asks an organisation to show how pay compares between women and men, using a ratio for basic salary and for total remuneration. In practice, it is about whether the organisation can explain the comparison clearly and consistently, rather than only giving a headline statement about equal pay. The focus is on the reported relationship between women’s and men’s pay, based on the organisation’s own workforce data.

The practical emphasis is on coverage and comparability: the organisation should be clear about which parts of the business are included, and whether the figures reflect the whole organisation or only selected sites, functions, or employee groups. A useful report will make it easy to see the scope of the data, so readers can understand how representative the ratio is and avoid mistaking a partial view for the full picture.

This LRA educational guidance supports disclosure preparation. For the exact requirements, always refer to the official GRI source.

Before you start

A quick mental checklist before you prepare this disclosure — tick each as you settle it.

Preparation

Key datapoints to prepare

Datapoint What to capture Evidence hint Owner
Key operating sites List the locations the organisation treats as its main operating sites, using the same basis applied in internal reporting. Group structure maps, site registers, management reporting packs, or location lists used for reporting. Finance / reporting
Worker group split Set out the employee groups used for reporting, with the organisation’s own category names and definitions. HRIS employee classification fields, payroll groupings, or workforce reporting definitions. HR / people analytics
Base pay gender ratio Calculate the percentage comparison between women’s and men’s basic pay using the same pay basis for both groups. Payroll extracts, pay review files, and calculation workbook showing the pay basis used. HR / reward
Total pay gender ratio Calculate the percentage comparison between women’s and men’s total remuneration using one consistent remuneration basis. Payroll, bonus, benefits, and remuneration calculation schedules supporting the final percentage. HR / reward
Site definition basis Record the rule the organisation uses to decide which locations count as main operating sites, including the threshold or test applied. Policy note, reporting methodology, or internal definition paper approved for the disclosure. Finance / reporting

How to prepare it

1Set the reporting boundary first: decide which sites count as material operating locations for this disclosure, and make sure the same boundary is used consistently across the figures and the explanation.
2Fix the employee grouping you will use before you calculate anything, so the pay comparison is built on one clear staff classification rather than mixed or shifting categories.
3Gather the underlying payroll evidence for the chosen population, including the pay data needed to compare women and men on both base pay and total pay, and keep the source records traceable.
4Calculate and present the two required percentages separately: one for base salary and one for overall pay, using the same scope and employee grouping for each result.
5Write down how you treated the term for material operating locations, including the definition you applied and any exclusions, assumptions, or changes from prior reporting periods.
6Check the final disclosure against the official source to confirm you have covered every required item, used the right scope, and not missed any supporting explanation or evidence.
Request the data

Request pay ratio data from People Analytics

Translate the disclosure into an internal business question — then adapt it to your organisation's own language.

How do pay levels for women and men compare across our main operating locations and employee groups, using the same basis for pay and total pay?

Use your organisation’s own labels first, then map them to the disclosure fields. For example, use your internal site names, job families, grades, pay elements and reporting periods rather than framework wording, and only translate them into the disclosure terms at the end.

Weak request

Please provide the GRI 405-2 data for significant locations of operation and employee categories, including the the evidence needed for GRI 405:GRI 405-2.

Why it fails: This uses framework language only and does not tell the owner which internal report, site list, pay basis, source file, or calculation method to use. It also leaves the definition of major operating locations unclear, so the returned data may not match the organisation’s own payroll and reward reporting.

Better request

Please send the pay comparison extract for [reporting period] using our internal site list and employee groupings. Include base pay and total pay comparisons for women and men, the source system or file, the calculation method, any exclusions, and the definition used for major operating locations. Please return the table with a short note on assumptions and who can approve it.

Industry examples
Manufacturing

Context. A group with several plants and a head office wants to compare shop-floor and office pay across its main sites.

Adapted request. Please provide the pay comparison table for [reporting period] covering our main plants and office locations. Use the internal site names, the workforce groups used in payroll reporting, and the same method for base pay and total pay. Include the source extract, exclusions, and the definition used for major operating sites.

Example response. Site: Midlands plant; Employee group: hourly production; Base pay ratio: 97%; Total pay ratio: 94%; Method: median comparison; Population covered: active employees only; Comments: overtime excluded from base pay, bonus included in total pay.

Financial services

Context. A firm with several business lines wants to compare pay across front office, operations and support teams in its main offices.

Adapted request. Please send the pay comparison extract for [reporting period] using our business-line and grade structure. Include the London and regional offices treated as major operating locations, the pay basis used for salary and total reward, the calculation method, and any exclusions or adjustments.

Example response. Location: London office; Employee group: analyst grades; Base pay ratio: 101%; Total pay ratio: 96%; Method: average comparison; Population covered: permanent staff; Comments: sign-on awards excluded, cash bonus included in total pay.

Draft your disclosure

Notes that turn data into a disclosure

LRA training templates — adapt them to your organisation, and check the official source before sign-off.

Method note

State which sites were treated as the organisation’s key operating locations, explain how employee groups were defined, and note the basis used to calculate each women-to-men pay comparison.

Context note

Explain what the ratios mean in practice by showing whether women’s pay sits below, at, or above men’s pay within each employee group and across the organisation’s main operating sites.

Fluctuation statement

If the ratios moved materially from the prior period, link the change to shifts in employee mix, site coverage, or pay-setting decisions, and note any one-off effects that affected the result.

Assurance readiness

For each claim, check the evidence

ClaimRiskEvidence to check
I used the same reporting boundary as the rest of the people data, and I checked that the coverage figure only includes the sites we had decided were in scope for this disclosure.An assurer may test whether the boundary was applied consistently, whether any sites were left out without a clear reason, and whether the coverage figure was calculated from the right population.Boundary memo or reporting policy; list of included and excluded sites; working papers showing how the coverage figure was built; sign-off from the data owner or preparer.
I grouped the workforce using the category set we applied for this report, and I kept a record of how each person was assigned so the disclosed split can be traced back to source records.An assurer may probe whether the category logic was applied consistently, whether people were placed in the right group, and whether the grouping could be reproduced from source data.Category definitions used for the report; HR or payroll extracts; mapping rules for assigning individuals to groups; reconciliation showing totals by category; review notes or approval trail.
I calculated the pay comparison from the underlying salary records for the selected employee groups, and I checked the inputs before publishing the figure.An assurer may question whether the salary data were complete and accurate, whether the right employee groups were used, and whether the calculation was performed correctly.Payroll or HR source files; calculation workbook; methodology note for the pay comparison; checks on completeness and accuracy; evidence of review before publication.
I prepared the pay-and-reward comparison from the underlying remuneration records, and I carried out a final check that the published ratio matched the working papers.An assurer may test whether all relevant pay elements were included as intended, whether the source data were reliable, and whether the final published number agrees to the calculation file.Remuneration data extracts; calculation model; list of included pay elements; reconciliation to source records; reviewer sign-off or publication approval.
I documented the rule we used to decide which sites counted as major for this disclosure, and I kept that rule with the working papers so the basis for inclusion is clear.An assurer may ask whether the definition was set before the numbers were prepared, whether it was applied consistently, and whether it is supported by internal records.Written definition or internal policy; rationale for the threshold or selection rule; list of sites assessed against the rule; working papers showing application of the definition; approval or governance record.

Evidence pack to prepare

Common reporting gaps

A percentage is stated without the underlying counts (numerator and denominator).The denominator — what the figure is a share of — is not explained.Partial scope is reported as if it were complete coverage.One-off activities are counted as if they were ongoing programmes.Boundary or period changes that move the figure are not flagged.Exclusions from the reported scope are not listed or explained.
Common gaps

Mistakes to avoid when collecting the data

Wrong owner, wrong language
The request goes to the wrong team because it is framed in disclosure jargon instead of the payroll, HR or reward terms people actually use.
No clear boundary
The data pull starts before the team has agreed which sites, worker groups and business units are in scope, so different people collect different populations.
Definition left vague
No one records how the organisation is using the phrase for major operating sites, so the same location can be included by one person and excluded by another.
Mixed time basis
One source is taken from a current payroll run while another is taken from a different cut-off date, so the figures do not relate to the same period.
Different counting bases
Basic pay and total reward are gathered from different calculation methods, which makes the two ratios impossible to compare cleanly.
Source labels stripped out
The original field names and system labels are lost during export, so the team cannot trace each number back to the payroll or reward report it came from.
Groups merged too early
Women and men are combined across employee categories or locations that should stay separate, which hides the differences the disclosure is meant to show.
Evidence trail missing
The team keeps the numbers but not the supporting extracts, date stamps and reviewer notes, so there is no audit trail for sign-off.
No review sign-off
The draft data pack is circulated without a named reviewer confirming the scope, definitions and source files, so errors can survive into the final disclosure.

Where judgement is often needed

Set the site list before calculating the ratios
Decide which operating sites count as significant, explain that basis, and keep the same site set for both pay measures unless a change in the business makes a revised scope necessary.
Explain how you treat bought-in or sold businesses
If acquisitions or disposals change the workforce covered, state whether you use the post-deal structure, a restated comparison set, or another consistent cut-off, and describe the effect on the figures.
Use one job-grouping method and say what it is
Where local job titles or grading systems differ across countries, map people into employee groups using a single documented approach and disclose that mapping so readers can see how like-for-like comparisons were made.
Be clear about people near the boundary
State how you handle workers who sit close to the scope line, such as part-time staff, fixed-term hires, secondees, or contractors if they are included in your pay population, and explain any exclusions.
Choose a single pay basis and keep timing aligned
If pay data can be taken from different payroll dates or pay periods, use one consistent cut-off for both women and men, explain the timing choice, and note any material timing mismatch.
Say when figures are measured and when they are estimated
If complete payroll records are not available for every site or group, disclose where you used estimates, the method used to fill gaps, and whether the same approach was applied across both pay measures.
Round in a way that does not distort the comparison
Apply one rounding rule to both ratios, disclose it if it affects the reported result, and avoid rounding at a level that hides a meaningful difference between the two figures.
Protect privacy when groups are small
Where a site or employee group is too small to show separately without risking identification, combine it with another group or present it at a higher level, and explain the aggregation choice.
Examples

Illustrative examples

Synthetic, written by LRA — not from a company report, not text from any standard.

Illustrative (synthetic) example — Food manufacturing

We have set out a synthetic illustration of pay comparison across our main operating sites, using our own working definition of major locations as those with 250 or more employees or where a site is operationally critical. The figures below compare women and men in each employee group at those sites, showing both base pay and total pay on a like-for-like basis.

Illustrative only: this example shows how a reporter might present the pay comparison for major sites and employee groups, alongside the site-screening rule used.

Illustrative (synthetic) example — Retail distribution

This synthetic illustration uses a site threshold of 100 or more workers, plus any depot that handles national fulfilment, to define the locations included. It compares women and men across our employee groups at those locations, for both base salary and overall pay.

Illustrative only: this example shows a different plausible way to define major locations and present the same pay comparison by employee group.

Scenarios to work through

A group reports pay data for three large sites: one in Manchester, one in Leeds and one in Dublin. The HR team has separate figures for shop-floor staff, supervisors and managers, but the draft note only lists the overall company average.

QWhat should you do before finalising the disclosure so the reader can see the pay comparison in the right places and staff groups?
Reveal model answer →

A preparer has calculated that women’s base pay is 92% of men’s in one employee group, but the remuneration figure is 88% because bonuses and allowances differ. The draft currently shows only the 92% figure because it looks simpler.

QCan you leave out the total-pay figure if the base-pay result is already available?
Reveal model answer →

The payroll team has used the phrase 'major operating sites' in the draft, but the internal methodology actually defines the relevant places as the three sites where most staff are based and where pay data is complete. The sustainability team is unsure whether to keep the internal phrase or explain it.

QWhat should the disclosure do about the way the relevant locations are defined?
Reveal model answer →

A draft table lists the ratios for women to men as 101% for senior managers and 97% for all other staff, but it does not say which employee groups those numbers relate to or whether the same site set was used for both measures. The team assumes the figures speak for themselves.

QWhat extra context is needed so the numbers are interpretable?
