A subsidiary is a separate legal entity controlled by a parent through voting rights, contractual rights, or another applicable control relationship.
A subsidiary is a separate legal entity controlled by another entity, called its parent. Control commonly comes from majority voting rights, but it can also arise with less than majority ownership through contractual rights, dispersed ownership, or other substantive decision-making power.
Subsidiary status is not determined by one universal shareholding threshold. Corporate law, securities regulation, U.S. GAAP, IFRS, tax law, and contracts can apply different definitions for different purposes.
A parent can obtain control by:
The analysis focuses on current substantive power, not just the legal title attached to the investment.
Under IFRS 10, an investor controls an investee when it has power over the investee, exposure or rights to variable returns, and the ability to use its power to affect those returns. U.S. GAAP uses voting-interest and variable-interest consolidation models. The result may be similar, but the analysis should not be assumed identical.
| Structure | Parent ownership | Outside ownership | Consolidation implication when control exists |
|---|---|---|---|
| Wholly owned subsidiary | 100% | None | Full consolidation; no non-controlling interest |
| Partially owned subsidiary | Less than 100% | Present | Full consolidation plus non-controlling interest |
| Indirect subsidiary | Held through another controlled entity | May be present | Included if the parent controls it indirectly |
| Former subsidiary | Parent has lost control | Investment may remain | Deconsolidation and subsequent accounting under applicable rules |
A 70%-owned entity is not reported as only 70% of each asset and liability when it is consolidated. The group reports the subsidiary’s full eligible accounts and identifies the outside claim separately.
Assume Parent owns 80% of Subsidiary S. During the period:
$50 million from external customers.$30 million from external customers.$5 million management fee.The two legal-entity income statements contain $85 million of total reported revenue: 50 + 30 + 5. From the group’s perspective, the $5 million fee is internal. Consolidated revenue is therefore $80 million before other adjustments.
The consolidated statements include 100% of S’s eligible revenue and expenses, not 80%. The outside shareholders’ claim on S’s adjusted net assets and profit is presented as non-controlling interest under the applicable accounting framework.
The parent-only statements can still show the management-fee income and investment in S because they report the parent legal entity rather than the economic group.
| Term | Separate legal entity? | Relationship to parent or investor |
|---|---|---|
| Subsidiary | Usually yes | Controlled by parent |
| Branch | Usually no | Operating location or division of the same entity |
| Affiliate | Depends | Connected through control, common control, or a defined relationship |
| Associate | Yes | Significant influence, but not control |
| Joint venture | Yes or contractual arrangement | Joint control under the applicable framework |
An associate is commonly accounted for under the equity method, while a subsidiary is consolidated when the relevant requirements are met.
A subsidiary can own assets, employ staff, enter contracts, sue or be sued, borrow, and incur liabilities in its own name. That separateness is a major reason groups use subsidiaries for acquisitions, geographic expansion, licensing, regulated activities, and asset ownership.
It does not guarantee isolation. Parent exposure can arise through:
An analyst should trace the actual obligation rather than assume every subsidiary liability belongs to the parent or none of it can reach the parent.
Legal-entity placement affects:
Consolidated profitability can look strong while parent liquidity is weak if cash is trapped in subsidiaries. Conversely, a loss at one subsidiary may be economically manageable if claims are genuinely contained and the parent has not guaranteed them.
