Consolidation Accounting: How Parent and Subsidiary Financial Statements Are Combined

What Triggers Consolidation: The Control Test

Under ASC 810, a parent must consolidate a subsidiary when it has a controlling financial interest in that entity. For voting interest entities, control is presumed when the parent owns more than 50% of the voting stock. This is the most common scenario in accounting courses and exams. However, legal ownership of more than 50% is neither necessary nor always sufficient — control can also exist through contractual arrangements, and majority ownership does not guarantee consolidation if the subsidiary's minority shareholders have substantive veto rights over ordinary operating decisions.

Investments below 50% — where the investor has significant influence but not control — use the equity method rather than consolidation. Investments below 20% where no significant influence exists are accounted for as financial instruments. For a full comparison, see the guide on equity method accounting.

The Acquisition Method at Consolidation Date

When a parent acquires a subsidiary under ASC 805, the acquisition method is used. At the acquisition date, the consolidated balance sheet is prepared by:

1. Taking 100% of the parent's assets and liabilities at book value
2. Adding 100% of the subsidiary's identifiable assets and liabilities at their acquisition-date fair value — not book value
3. Recognising goodwill (or a bargain purchase gain) for any difference between the consideration transferred plus NCI and the net fair value of identifiable assets and liabilities
4. Eliminating the parent's investment account against the subsidiary's equity

Example: Parent Corp pays $800,000 for 80% of Sub Inc. Sub's identifiable net assets have a fair value of $900,000 (book value was $700,000). NCI (20%) is valued at $200,000.

Calculating Goodwill

Goodwill arises when the total of consideration paid plus NCI exceeds the fair value of the identifiable net assets acquired. Under the full goodwill method (required under US GAAP), NCI is measured at fair value — meaning the full goodwill is attributed to the combined entity, not just the parent's share. This is why goodwill in the example above is $100,000, not $80,000 (80% share).

Goodwill is not amortised under US GAAP. Instead, it is tested for impairment at least annually at the reporting unit level. If the carrying value of the reporting unit exceeds its fair value, goodwill is written down by the excess. For the full treatment of goodwill and business combinations, see the ASC 805 guide.

Non-Controlling Interest

Non-controlling interest (NCI) — formerly called minority interest — represents the portion of a subsidiary's equity that belongs to shareholders other than the parent. Under current GAAP, NCI is presented within equity on the consolidated balance sheet, not as a liability or mezzanine item.

On the consolidated income statement, the subsidiary's full revenue and expenses are included (100%), and then the portion of net income attributable to NCI is deducted to arrive at net income attributable to the parent. The NCI balance on the balance sheet is updated each period: beginning NCI + NCI share of subsidiary net income − NCI dividends received from subsidiary.

Post-Acquisition Consolidation Entries

In every period after the acquisition, the parent and subsidiary prepare their own separate financial statements, then a consolidated worksheet is prepared to combine them. The key worksheet eliminations in each subsequent period include:

Investment elimination entry: Eliminates the parent's investment account against the subsidiary's equity accounts (as restated to fair value at acquisition). This entry is made every period because the parent's books still carry the investment at its original cost (under the cost method) or adjusted carrying value (under the equity method).

Amortisation of fair value adjustments: The difference between fair value and book value of identifiable assets at acquisition must be depreciated or amortised each year. For example, if a building was written up by $200,000 and has a 20-year remaining life, an additional $10,000 per year of depreciation must be recognised in the consolidated statements.

Eliminating Intercompany Transactions

Any transactions between the parent and subsidiary must be completely eliminated in consolidation — otherwise the consolidated statements would double-count economic activity. Common intercompany eliminations:

Intercompany sales: If Parent sells inventory to Sub for $50,000 (costing Parent $30,000), and Sub still holds the inventory at year-end, the consolidated statements must eliminate the $50,000 intercompany revenue and $50,000 cost of goods sold, and reduce the inventory balance by the $20,000 unrealised profit embedded in Sub's inventory.

Intercompany loans: The intercompany note receivable on Parent's books and the note payable on Sub's books cancel each other out. The interest income and interest expense also eliminate against each other.

Intercompany dividends: Dividends paid by Sub to Parent are eliminated — the parent's dividend income disappears and the reduction in Sub's retained earnings is eliminated.

Variable Interest Entities

The voting interest model fails when an entity is structured so that voting rights do not accurately reflect economic exposure to risk and reward. Variable interest entities (VIEs) — often used in special purpose structures, securitisations, and joint ventures — are consolidated by the primary beneficiary: the entity that has both the power to direct the activities that most significantly affect the VIE's economic performance AND the obligation to absorb losses or right to receive benefits that could be significant. This VIE model was introduced after Enron's off-balance-sheet abuses and is tested on the FAR exam.
