What it means
Consolidation is driven by control, not by ownership percentage. Once a parent owns more than half the voting shares of another company, accounting rules require it to add 100% of that subsidiary's revenue, costs, assets and liabilities into the group accounts.
Minority interest is the correcting entry that stops the group claiming profits and net assets that belong to somebody else. The figure matters because it changes what the headline numbers actually mean.
A group reporting $50,000,000 of revenue may be entitled to only part of the profit that revenue produces, and anyone who ignores the non-controlling interest line will overstate what belongs to the parent's shareholders. There are two places to look for it.
On the balance sheet, minority interest sits within equity, below the parent's own reserves, representing the outside shareholders' claim on the subsidiary's net assets. On the income statement, total group profit is split into an amount attributable to the parent and an amount attributable to non-controlling interests.
Measurement has a wrinkle worth knowing about. At the acquisition date the non-controlling interest can be measured either at its proportionate share of the subsidiary's identifiable net assets or at full fair value, and the second method places more goodwill on the balance sheet.
The choice is made deal by deal, so two groups with almost identical economics can report different equity totals. Always watch the gap between control and economics.
A parent holding 51% consolidates everything but keeps only about half the profit, which is why lending covenants and per-share measures are normally written against the parent's attributable figures rather than the group totals.
In practice
Real-world examples
Example 1
A listed brewing group owns 70% of a bottling plant in another country. Group accounts show all $28,000,000 of the plant's revenue, but 30% of its $2,000,000 profit, or $600,000, is reported as attributable to non-controlling interests.
Example 2
A property developer forms a joint venture with a local partner, taking 60% and control of the entity. Because it controls the venture it consolidates rather than equity accounts, and the partner's 40% share appears as minority interest in both equity and profit.
Example 3
An analyst valuing a telecoms group notices that earnings per share is calculated on profit attributable to the parent, not group profit. The gap is $18,000,000, and adjusting for it moves the valuation multiple enough to change a buy recommendation into a hold.
Think of it
Imagine buying a house with three friends where you put in 80 percent of the money and they put in 20 percent. You get to make all the renovation decisions and manage the property, but when selling tickets for a house tour, you must acknowledge that a portion of the building belongs to your friends.
Formula
Calculation
Minority interest in net assets = non-controlling ownership % x subsidiary net assets
Minority interest in profit = non-controlling ownership % x subsidiary net profit
A parent buys 80% of a regional distribution company, leaving 20% with outside shareholders. The subsidiary has net assets of $5,000,000, so the minority interest reported within group equity is 20% x $5,000,000 = $1,000,000.
In the same year the subsidiary earns a net profit of $1,500,000 while the parent's own operations earn $4,000,000. Consolidated group profit is $4,000,000 + $1,500,000 = $5,500,000. Of that, 20% x $1,500,000 = $300,000 is attributable to non-controlling interests, leaving $5,500,000 - $300,000 = $5,200,000 attributable to the parent's shareholders.Case study
Seen in the real world
The following is an illustrative and entirely fictional example. Brambleford Logistics, an invented freight group, acquired 75% of a last-mile delivery firm with net assets of $12,000,000. The non-controlling interest recorded within group equity at acquisition was 25% x $12,000,000 = $3,000,000.
In its first full year under Brambleford's control, the delivery firm produced net profit of $2,400,000, of which 25% x $2,400,000 = $600,000 belonged to the minority holders. Brambleford's own operations earned $7,600,000, so group profit was $7,600,000 + $2,400,000 = $10,000,000 while profit attributable to Brambleford's shareholders was $10,000,000 - $600,000 = $9,400,000.
The board's first press release led with the $10,000,000 figure, and several shareholders assumed earnings per share had risen accordingly. In this fictional scenario the finance director rewrote the release to lead with the $9,400,000 attributable figure, which avoided an awkward correction once the full accounts were published.
Watch out
Common mistakes
- Treating minority interest as a liability. It sits within equity because outside shareholders are owners of the group's subsidiary, not creditors of it.
- Consolidating only the parent's ownership share of a subsidiary. Control means all of the subsidiary goes in, with the outside share stripped out afterwards.
- Comparing groups on total profit without checking how much of it is attributable to the parent, which flatters companies that own subsidiaries only partly.
Questions
People also ask
Is minority interest the same as non-controlling interest?
Yes, non-controlling interest is the current term used in both major accounting frameworks and minority interest is the older name that many people still use.
Does a 30% stake in another company create minority interest?
No, a stake that small usually means no control, so the holding is equity accounted or held as an investment rather than consolidated.
How does minority interest affect enterprise value?
It is normally added to enterprise value alongside debt, because the operating figures being valued include 100% of the subsidiary while the parent's equity does not.
