What it means
Affiliation comes in two broad shapes. Vertical affiliation runs up and down an ownership chain, as with a parent and a subsidiary, while horizontal affiliation links companies that have no stake in each other but share a common owner, often called sister companies.
The practical importance is that affiliated companies can set prices between themselves. A parent can sell components to its own subsidiary at almost any figure, moving profit from one entity to another, which is why transfer pricing rules require such transactions to be priced as they would be between unrelated parties.
In consolidated accounts, transactions between affiliated companies inside the same group are eliminated. Sales from a parent to its subsidiary, and any profit still sitting in unsold stock, are removed so that the group only reports revenue and profit earned from outside customers.
Where a parent owns less than all of a subsidiary, the portion of the subsidiary's profit and net assets belonging to other shareholders is shown separately as a non-controlling interest. This lets a reader see how much of the reported profit actually belongs to the parent's own shareholders.
Beyond accounting, the affiliated label triggers obligations in several areas: related-party disclosure in the notes to accounts, restrictions on lending between affiliated financial institutions, group relief and thin capitalisation rules in tax, and combined turnover tests in competition filings. Different rulebooks set different ownership thresholds, so a company can be an affiliate for one purpose and not for another.
In practice
Real-world examples.
Example
A hotel group holds its properties in one company and its management business in another, both wholly owned by the same holding company. The two are affiliated, and the management fee charged between them must be set at a commercial rate to satisfy tax authorities.
Example
A manufacturer sells $9,000,000 of parts a year to an affiliated assembly company in another country. Auditors request a transfer pricing study to confirm the price matches what an unrelated buyer would pay.
Example
A retail group's finance director eliminates $12,000,000 of intercompany sales when preparing consolidated accounts, so group revenue reflects only sales to external customers rather than internal movements of stock.
Formula
Calculation
Consolidated revenue = combined revenue of group companies - intercompany sales
Non-controlling interest in profit = subsidiary net income x percentage not owned by the parent
A parent company owns 100% of Company A and 60% of Company B, so A and B are affiliated companies. The parent reports standalone revenue of $50,000,000, which includes $4,000,000 of components sold to Company A.
Consolidated revenue contributed by the parent = $50,000,000 - $4,000,000 = $46,000,000
Company B, the 60% owned subsidiary, earns net income of $3,000,000 for the year.
Share attributable to the parent's shareholders = $3,000,000 x 60% = $1,800,000
Non-controlling interest = $3,000,000 x 40% = $1,200,000
The group therefore reports $46,000,000 of revenue from the parent rather than $50,000,000, and splits Company B's $3,000,000 profit between $1,800,000 for the group's own shareholders and $1,200,000 for the outside shareholders of Company B.Case study
Seen in the real world.
This is an illustrative, fictional case. Penrose Holdings, an invented family group, owned three affiliated companies: a bakery, a property company that owned the bakery's premises, and a logistics company that delivered its products. Each filed its own accounts, and the family judged performance one company at a time.
The property company charged the bakery rent of $1,300,000 a year, well above the $700,000 an independent tenant would have paid for comparable space. The effect was to make the property company look highly profitable and the bakery look marginal, which nearly led the family to close the bakery's second production line.
When the group prepared consolidated accounts for the first time, the intercompany rent and delivery charges were eliminated and the picture reversed: the bakery was the profitable operation and the property company was simply collecting an inflated internal charge. Penrose reset the rent to a market rate, kept the second line open, and adopted consolidated reporting as the basis for every future decision.
Watch out
Common mistakes.
- Adding up the revenue of every affiliated company to describe group size. Without eliminating intercompany sales, the total double counts internal transactions and overstates the group.
- Setting prices between affiliated companies for convenience or tax advantage. Transfer pricing rules require arm's length pricing, and adjustments plus penalties can be severe.
- Treating non-controlling interest as a liability of the group. It is a portion of equity belonging to other shareholders of a subsidiary, not an amount the group owes.
Questions
People also ask.
Are affiliated companies the same as a group?
A group usually means a parent and the subsidiaries it controls, while affiliated companies is a wider term that also covers sister companies and entities linked by influence rather than control.
Can affiliated companies file one tax return?
It depends on jurisdiction, since some allow group filing or loss relief between affiliated entities while others require each company to file separately.
Why do regulators care about affiliation?
Because related entities can shift profits, guarantee each other's debts and combine market power, so disclosure and pricing rules exist to make those links visible.
