A group consolidation audit is substantially more involved than a single-entity audit. The auditor is not only verifying that individual entity figures are correct — they are verifying that the process of combining those figures into group financial statements has been performed correctly, with the right entities included, the right eliminations applied, and the right accounting judgments documented.
Audit preparation for consolidated financials is most effective when the finance team knows specifically what auditors will request — and has prepared that documentation before fieldwork begins, not in response to audit queries. This post covers the eight areas auditors focus on in a group consolidation audit and what documentation each requires.
The Eight Consolidation Audit Focus Areas
01Consolidation scope — which entities are included and why
Auditors verify that the right entities have been consolidated — that IFRS 10 (or ASC 810) control was correctly assessed for each entity in the group, and that any entities excluded from the consolidation have a defensible basis for exclusion. Any changes in scope during the year — new acquisitions, disposals, entities wound up — require specific documentation of the date control was obtained or lost.
Prepare: Group entity register with ownership percentages, control assessment rationale for each entity, and dates of any scope changes during the year.
02Intercompany elimination schedule
Every elimination entry must be traceable to a source intercompany transaction. Auditors will select a sample of elimination entries and request the underlying documentation — the invoice, loan agreement, or management fee schedule — and confirmation that both sides of the transaction agree in amount. They will also check that the eliminations are complete: that no intercompany balance remains unadjusted in the consolidated statements.
Prepare: A formal elimination schedule listing every entry by counterparty, amount, account, and period — with reference to the source document. Not a spreadsheet; a structured working paper file.
03Exchange rate documentation and consistency
Auditors verify that the correct rates were applied — closing rate for balance sheet items, average rate for P&L items — and that these rates were applied consistently across all entities. They will ask for the rate source and check that the rates used match the published source rates for the relevant dates. Any FX differences in intercompany eliminations (residuals from rate inconsistency) will require explanation.
Prepare: The period-end rate table with source documentation (ECB, MAS, or other central bank reference rates), evidence that the table was published before entities submitted data, and a note explaining any FX residuals in the elimination schedule.
04PPA and acquisition accounting
For any acquisition made in the year (or within the 12-month measurement period), auditors will review the full PPA — the fair value of consideration, the fair values assigned to each identifiable asset and liability, the deferred tax liability on fair value uplifts, and the resulting goodwill. For intangible assets valued by external specialists, the specialist’s report is required. The amortisation of PPA intangibles must be traced from the acquisition date.
Prepare: PPA working paper, external valuation reports, amortisation schedule from acquisition date, and evidence that the measurement period has not expired without finalisation.
05Goodwill impairment testing
IAS 36 requires annual goodwill impairment testing (or more frequently if indicators arise). Auditors assess whether the CGU definitions are appropriate, whether the impairment model is correctly constructed, and whether the recoverable amount (VIU or FVLCD) exceeds the CGU’s carrying amount including allocated goodwill. Significant judgment is involved — particularly in the discount rate and growth rate assumptions — and auditors will challenge aggressive assumptions.
Prepare: The impairment model with documented CGU definitions, recoverable amount calculations, key assumptions, and sensitivity analysis on discount rate and terminal growth rate. For material goodwill, consider engaging external support for the VIU calculation.
06Significant accounting judgments and estimates
Auditors pay particular attention to areas where management has exercised significant judgment: provisions, revenue recognition, going concern, deferred tax asset recognition, and useful life estimates for long-lived assets. Each significant judgment should be documented — what was considered, what the conclusion was, and why the conclusion is supported by the evidence available.
Prepare: A significant judgments memo covering each material estimate and judgment in the consolidated accounts. This is the document auditors reference when challenging a conclusion — it should be prepared before fieldwork, not drafted in response to an audit query.
07Related party disclosures
IAS 24 requires disclosure of all material related party transactions and outstanding balances. Auditors verify completeness — that all related party relationships have been identified, that transaction volumes are correctly stated, and that the terms of material transactions are disclosed. In a group context, intercompany transactions between the consolidated entities are typically not related party transactions in the consolidated accounts (they’re eliminated) — but transactions with associates, joint ventures, or entities related to key management personnel are.
Prepare: Related party register identifying all relevant relationships; a schedule of transaction volumes and outstanding balances for each relationship during the year; terms and conditions of material transactions.
08Opening balance agreement
Auditors confirm that the prior year audited closing balance sheet agrees to the opening balance sheet used in the current year consolidation. Any differences — for example, if the consolidation working papers were updated after the prior year audit was completed — must be explained and documented. For newly acquired entities, the opening balance is the fair value of net assets at acquisition date; auditors will check this agrees to the PPA.
Prepare: A reconciliation from prior year audited consolidated balance sheet to current year opening position. Flag any adjustments made post-audit.
Timing: What to Prepare Before Fieldwork Begins
The finance team that prepares the most smoothly for a consolidation audit is the one that treats audit preparation as part of the close process — not as a separate exercise that starts when the auditors arrive. By the time fieldwork begins, the following should already exist:
- Entity register with control assessments
- Complete elimination schedule with source references
- Rate table with source documentation
- PPA schedule with external valuations (if applicable)
- Goodwill impairment model
- Significant judgments memo
- Related party register and transaction schedule
- Prior year reconciliation
💡 The fastest audits have one thing in common: The audit team was provided a complete set of working papers on day one of fieldwork, with a clear index and no missing items. Every hour an auditor spends waiting for documentation is an hour added to the audit timeline — and typically an hour billed at audit rates. The investment in pre-audit preparation has a direct ROI in audit cost and timeline.
For groups preparing for their consolidation audit, BrizoConsol maintains the elimination schedule, rate documentation, and consolidation adjustments in a structured audit trail — so the working papers that auditors request are available from the system, not reconstructed from memory or email archives.
