What it means
The key idea is the split between legal separateness and economic unity. The subsidiary signs its own contracts and files its own accounts, yet from an investor's point of view the parent and the subsidiary are one economic unit.
That is why the parent must produce consolidated accounts. Line by line, the subsidiary's revenue, costs, assets and liabilities are added to the parent's, and any transactions between the two are stripped out so the group does not appear to have sold things to itself.
The advantage over a partly owned subsidiary is simplicity. With 100% ownership there is no non-controlling interest line in the accounts, no minority shareholder to consult, and no argument about how profits or dividends should be shared.
Groups create wholly owned subsidiaries for practical reasons. A separate entity can isolate the liabilities of a risky venture, satisfy a country's requirement for a local company, hold intellectual property, or make a future disposal of one business unit far easier to execute.
The limitation people underestimate is that separateness is not absolute. Lenders routinely demand parent guarantees, regulators can look through the structure in some circumstances, and a parent that runs a subsidiary as a mere extension of itself may find the legal protection thinner than assumed.
Tax is usually the deciding factor in how these structures are designed. Group relief, transfer pricing rules on intercompany charges, and withholding tax on dividends paid between countries all shape whether a subsidiary is the sensible answer or an expensive complication.
In practice
Real-world examples.
Example
A manufacturing group sets up a wholly owned subsidiary in a new export market because local law requires a registered local company to hold the operating licence. Losses in the first two years stay inside that entity and do not expose the parent's other assets.
Example
A media company puts its live events business into a wholly owned subsidiary ahead of a possible sale. Two years later it sells the shares of that subsidiary rather than a messy list of individual contracts and assets.
Example
A retail group holds all its property in a wholly owned subsidiary that leases the stores to the trading company. The structure makes it clear how much of group profit comes from retailing and how much from owning property.
Formula
Calculation
Not a single formula, but consolidation follows a clear rule: Consolidated figure = Parent figure + Subsidiary figure - Intercompany transactions, with no deduction for non-controlling interest because the parent owns 100%.
A parent company reports revenue of $48,000,000 and a wholly owned subsidiary reports revenue of $12,000,000. During the year the subsidiary sold $3,000,000 of components to the parent. Consolidated revenue = $48,000,000 + $12,000,000 - $3,000,000 = $57,000,000. On profit, if the parent earns $5,600,000 and the subsidiary earns $2,400,000, consolidated profit is $8,000,000 and the whole amount is attributable to the parent's shareholders. Had the parent owned only 75%, $600,000 of that profit ($2,400,000 x 25%) would have been shown as attributable to non-controlling interests instead.Case study
Seen in the real world.
This is a fictional, illustrative account. Aldermere Group ran a stable industrial supplies business alongside a new and unpredictable robotics venture inside the same legal entity. When the robotics contract with a large customer went badly and a $1,900,000 claim landed, the entire group's assets, including the profitable supplies business, sat exposed to it.
After settling for $1,100,000, the fictional board restructured. Robotics was moved into Aldermere Robotics Ltd, a wholly owned subsidiary with its own directors, bank account and insurance, capitalised with $800,000 and instructed to sign contracts in its own name. Group consolidated revenue was unchanged at $34,000,000, since consolidation simply added the entities back together, but the risk profile was very different.
Two years later the robotics business needed outside capital. Because it was already a clean, separate entity with three years of standalone accounts, Aldermere was able to sell 30% of it to an investor in ten weeks, at which point the subsidiary stopped being wholly owned and a non-controlling interest line appeared in the group accounts for the first time.
Watch out
Common mistakes.
- Believing a subsidiary structure makes the parent immune from all liability. Parent guarantees, undercapitalisation and direct involvement in the subsidiary's decisions can all pierce that protection.
- Forgetting to eliminate intercompany sales when consolidating. Leaving them in inflates group revenue and can seriously mislead anyone reading the accounts.
- Assuming cash in the subsidiary is freely available to the parent. Moving it usually requires a dividend, a loan or a service charge, each with its own tax and legal consequences.
Questions
People also ask.
Does a wholly owned subsidiary file its own accounts?
In most jurisdictions yes, although small subsidiaries within a group can sometimes claim exemptions if the parent guarantees their liabilities.
What is the difference between a subsidiary and a branch?
A subsidiary is a separate legal company, whereas a branch is part of the parent itself and carries no separate liability shield.
Can a wholly owned subsidiary pay dividends to its parent?
Yes, provided it has distributable reserves, and those dividends are then eliminated on consolidation so group profit is not counted twice.
