Consolidated accounts in Luxembourg, Lux GAAP or IFRS, audit-ready.

What is financial consolidation?

Financial consolidation is the accounting operation that presents a set of legally distinct companies as a single economic entity. It starts from the individual accounts of the parent and each subsidiary, harmonises them so they rest on the same measurement rules, then neutralises everything that exists only inside the group: sales between subsidiaries, reciprocal receivables and payables, internal margins held in inventory, dividends paid upstream.

The difference from simply adding the accounts together is structural. Aggregation double-counts flows. If a manufacturing subsidiary invoices €4 million to a distribution subsidiary which then sells on to external customers, aggregation shows the same turnover twice. Consolidation keeps only the sale made with a third party. This is why a group moving from aggregated to consolidated financial statements often sees turnover fall without having lost any activity.

Consolidated financial statements comprise a consolidated balance sheet, a consolidated profit and loss account and consolidated notes, together with a consolidated management report. Under IFRS a cash flow statement and a statement of changes in equity are added; Lux GAAP does not require them, although most groups produce them anyway for their banks.

Three audiences use these accounts for different reasons. Banks read the group's real indebtedness, stripped of internal financing that artificially inflates aggregated liabilities. Investors read consolidated profitability. Directors read each entity's actual contribution, once internal recharges that shift margin between subsidiaries without creating value have been removed.

Consolidation thresholds in Luxembourg: when the obligation is triggered

A Luxembourg parent is exempt from preparing consolidated accounts as long as the undertakings to be consolidated do not exceed two of the following three criteria, assessed on the basis of their latest annual accounts: €25 million balance-sheet total, €50 million net turnover and 250 employees on average over the year.

Those amounts assume intercompany balances have already been eliminated. Where the calculation is made on simply aggregated figures, without elimination, the balance-sheet and turnover criteria are increased by 20%, to €30 million and €60 million. The 250-employee criterion is not increased. This dual reading avoids forcing a group to run a full consolidation merely to find out whether it has to consolidate.

The thresholds come from the Grand-Ducal regulation of 25 October 2024, which raised all Luxembourg accounting thresholds to account for inflation, following Delegated Directive (EU) 2023/2775. They apply to financial years beginning on or after 1 January 2023. Groups still working from the earlier €20 million and €40 million figures are using a superseded basis.

Two reading errors recur. The first confuses these group thresholds with the size thresholds of a standalone company, which are considerably lower and determine the annual accounts category and the obligation to appoint a réviseur d'entreprises agréé. The second reasons on the parent alone, whereas the assessment covers the whole scope. A holding company with no activity of its own can cross the thresholds purely through the addition of its subsidiaries.

Beyond the size exemption there is a sub-group exemption. A Luxembourg intermediate parent held by a group that already consolidates it at a higher level can rely on it, subject to publication of the top parent's consolidated accounts and disclosure in the notes. That exemption falls away as soon as a group company has securities admitted to trading on an EU regulated market.

Consolidation scope and applicable methods

Scope is determined by control, not by ownership percentage. A 45% holding combined with a shareholders' agreement giving a majority on the board places the subsidiary in full consolidation; a 55% holding whose voting rights are neutralised by agreement may fall outside. The work therefore begins with reading the articles, the shareholders' agreements and the governance arrangements, not with the ownership chart.

Full consolidation applies to controlled entities. The subsidiary's assets and liabilities enter the group accounts line by line, and the share not attributable to the parent is shown separately as non-controlling interests. The equity method applies to associates, entities over which the group exercises significant influence without control: a single balance sheet line for the share of net assets, and a single line in the result.

Lux GAAP retains an option of proportional consolidation for jointly managed undertakings, taking up the share of each caption. IFRS removed it for joint ventures with IFRS 11, which requires the equity method and reserves line-by-line recognition for joint operations. For a group holding significant joint ventures, that single point can materially change the presentation of the balance sheet depending on the framework chosen.

Scope is not static. An acquisition made during the year only enters the profit and loss account from the date control is obtained, a disposal leaves it at the date control is lost, and an entity in liquidation calls for specific treatment. We document every scope movement in the consolidation file, because it is the first point the réviseur d'entreprises agréé examines.

Intercompany eliminations and harmonisation restatements

Intercompany eliminations are handled by nature. Reciprocal accounts, receivables and payables between group companies, cancel out in pairs. Internal income and expenses disappear from the profit and loss account. Dividends paid by a subsidiary to its parent are removed from the consolidated result, since the corresponding profit has already been included through the subsidiary's own result.

Internal margins in inventory require more attention. Where one subsidiary has sold another goods still unsold at the reporting date, the margin included in the inventory value has not been realised with a third party. It must be neutralised, together with the corresponding deferred tax effect. This is the restatement most often omitted in spreadsheet-based consolidations, and the one auditors test first.

Reconciliation of reciprocal accounts precedes any elimination. Two subsidiaries rarely show identical balances: month-end cut-off differences, exchange differences, credit notes not yet recorded, disputed invoices. We require a contradictory reconciliation between entities before the close, with a documented tolerance threshold beyond which the difference must be explained rather than simply booked as a consolidation difference.

Harmonisation restatements then align policies. Divergent depreciation periods between subsidiaries, provisions computed on different bases, foreign subsidiaries kept under a local framework to be converted to the group's Lux GAAP or IFRS, lease contracts treated differently across countries. Currency translation of subsidiaries completes the process: closing rate for the balance sheet, average rate for the result, difference recognised in equity.

First-time consolidation: goodwill and comparatives

A group's first consolidation is a different exercise from subsequent closes. The history of acquisitions must be reconstructed, the price paid allocated to identifiable assets and liabilities at fair value as at the date control was obtained, and the residual difference determined. That difference, or goodwill, represents what was paid over and above the value of the identifiable items.

Subsequent treatment of goodwill separates the two frameworks sharply. Under Lux GAAP, goodwill is amortised over its useful life; where that life cannot be reliably estimated, Directive 2013/34/EU frames the amortisation within a five to ten year range. Under IFRS, IFRS 3 prohibits amortisation of goodwill and requires an annual impairment test. A group switching framework therefore sees its consolidated result change without any economic transaction having occurred.

Comparatives are the second difficulty. Publishing consolidated accounts means presenting the prior year on a consistent basis, which implies consolidating two financial years on the first pass. Groups almost always underestimate this workload, which accounts for most of the lead time of a first consolidation.

We treat this initial project separately from recurring closes, with a distinct deliverable: documentation of purchase price allocations, a bridge from aggregated to consolidated accounts, and a group consolidation manual setting the rules for subsequent years. That manual is what makes the second consolidation three times faster than the first.

Consolidation audit and filing with the register

Where the law requires consolidated accounts, they are subject to audit by a réviseur d'entreprises agréé. That obligation stands on its own: it does not depend on the audit regime applicable to each company's annual accounts taken individually. A group in which no entity is individually audited may therefore have to have its consolidated accounts audited.

FSL does not perform that statutory audit. Our role stops at producing an audit-ready consolidated pack and consolidation file, then coordinating with the audit firm. This separation is not a commercial limitation but an independence requirement: the party preparing the accounts cannot be the one certifying them.

An audit-ready file contains, as a minimum, the dated group structure chart with ownership and control percentages, the justification of scope and of the method applied to each entity, individual reporting packs reconciled to the statutory accounts, the detail of eliminations and restatements with their supporting evidence, the movement schedules for equity and goodwill, and the bridge from aggregated to consolidated accounts. A file structured this way shortens audit time, and therefore audit fees.

The consolidated accounts, the consolidated management report and the auditor's report are then filed with the Trade and Companies Register and published. We align that calendar with the approval calendar for the annual accounts, since both processes share the same governance constraints and often the same teams.

Consolidation software: when the spreadsheet reaches its limit

A spreadsheet is enough while a group has two or three subsidiaries, in a single currency, with a common chart of accounts and few reciprocal transactions. Beyond that, three signals indicate the limit has been passed: the consolidated close takes longer than all the individual closes combined, nobody can reproduce the prior year's restatements, and the auditor asks the same questions every year for want of an audit trail.

A dedicated consolidation tool, of the CPM type, provides three things a spreadsheet does not: traceability of every consolidation entry back to its supporting evidence, automatic reproducibility of recurring restatements from one year to the next, and built-in control of intercompany reconciliations before the close. We work on a tool of this type, which makes eliminations reliable and shortens recurring closes.

This tool is distinct from the accounting software each entity uses day to day. The latter keeps a company's general ledger, produces its trial balance and feeds Luxembourg filing obligations. The former consumes those trial balances and turns them into group accounts. On the choice of bookkeeping software, see accounting software in Luxembourg.

The decision to invest in a tool rests on a simple calculation. Compare the annual cost of the tool and its configuration with the internal time spent on the consolidated close, plus the audit surcharge caused by a poorly documented file. For a group with more than five consolidated entities, the calculation usually favours the tool from the second year.
