- Reporting scope
- Consolidated group
- Auditor
- RSM UK Audit LLP
- Audit opinion
- Unqualified (clean)
- Going concern
- Affirmed
“The group and LLP are well positioned as part of a global legal business to continue delivering effective, high quality legal services and the members are confident in the future of the business. Based on the expected performance of the group, taking account of the wider economic factors as noted in the Members' report on page 2, and alongside their commitment to sound financial management, the members believe that it is appropriate to continue to adopt the going concern basis of accounting in preparing the annual financial statements. The performance of the group and the LLP since the balance sheet date including the work currently in hand and anticipated, as well as the forecasts covering the 12 months from the approval of these financial statements is consistent with that belief.”

Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers
