A subsidiary is a company controlled by another company, its parent, ordinarily through ownership of a majority of its outstanding voting shares. It stays a separate legal entity with its own organizational documents, its own books and its own liabilities, even while its results are reported inside the parent’s group financial statements whenever the parent consolidates it. Control can also rest on a contract rather than on shares, and a company can be the subsidiary of a parent that holds none of its shares directly.
Who Counts as a Subsidiary
The SEC’s accounting rules define the pair together. A subsidiary of a specified person is an affiliate controlled by such person directly, or indirectly through one or more intermediaries, and a parent is an affiliate controlling such person on the same terms (17 CFR 210.1-02(x), (p) and (g)). Control in those rules means the possession, direct or indirect, of the power to direct or cause the direction of the management and policies of a person, whether through the ownership of voting shares, by contract, or otherwise. Shares are the usual route to that power, not the definition of it.
The same rules grade the ownership levels instead of leaving the word vague. A majority-owned subsidiary is one whose parent, together with the parent’s other majority-owned subsidiaries, owns more than 50 percent of its outstanding voting shares. A wholly owned subsidiary is one whose parent, together with the parent’s other wholly owned subsidiaries, owns substantially all of its outstanding voting shares. A totally held subsidiary goes one step further: substantially all of its outstanding equity securities are owned by its parent, together with the parent’s other totally held subsidiaries, and it owes nothing material to anyone outside that set, apart from ordinary course borrowing that is not overdue and matures within 1 year of when it was created (17 CFR 210.1-02(n), (aa) and (y)).
Direct and Indirect Ownership
“Indirectly through one or more intermediaries” does real work in that definition. A company two levels down a chain is still the parent’s subsidiary, even though the parent holds none of that company’s shares directly. What the chain does not preserve is the percentage.
Parent owns of First Sub 80%
First Sub owns of Second Sub 60%
Parent's indirect economic interest in Second Sub 80% x 60% = 48%The parent’s economic slice of the second company falls below half, and the second company is a subsidiary anyway, because control passes down the chain while the arithmetic share of its profits does not. A tiered holding can look small on an ownership schedule and still pull a whole entity into the group.
The Separate Entity Survives Consolidation
Consolidation changes the reporting, not the entity. A parent that controls a subsidiary presents the two as one reporting entity and strips out what they did with each other, which is the subject of consolidations. Nothing in that presentation merges the companies. The subsidiary keeps its own organizational documents, its own contracts and its own state filings, and one set of group statements is a presentation laid over two legal persons.
Liability follows the same line. A parent corporation is not liable for the acts of its subsidiaries, a principle of corporate law the Supreme Court has treated as general and deeply established, and the exception is that the corporate veil may be pierced (United States v. Bestfoods, 524 U.S. 51 (1998)). That principle covers liability derived from what the subsidiary did. It does not shelter a parent from liability for what the parent itself did.
How a Subsidiary Shows Up in a Firm’s Work
A subsidiary is a separate closing job before it is a line in anyone’s group report. It runs its own chart of accounts, posts its own journal entries and produces its own trial balance, and that trial balance has to balance and close on its own period end before group reporting can begin. A group of five entities is five closes plus the group work, not one larger close, so adding an entity can move a firm’s deadline by more than the entity’s size suggests.
The intercompany accounts are where the separateness becomes visible in the ledger. Each company records its side of a transaction with the other in its own books, as a real receivable or payable to a related party, because each set of books is kept on a standalone basis for a separate legal person.
Where a Company’s Subsidiaries Are Listed
For a public company the list is filed rather than inferred. A registrant has to list all subsidiaries, the state or other jurisdiction of incorporation or organization of each, and the names under which those subsidiaries do business (17 CFR 229.601(b)(21)). The exhibit is organized by legal entity, so a brand appears only where it is a name one of those subsidiaries does business under. A product line or trademark the registrant holds itself is not on the list, while entity names nobody markets are on it.
Two omissions are allowed. Particular names may be omitted if the unnamed subsidiaries, considered in the aggregate as a single subsidiary, would not constitute a significant subsidiary as of the end of the year covered by the report, and the names of consolidated wholly owned subsidiaries carrying on the same line of business may be omitted as well, provided the immediate parent, the line of business, the number of omitted subsidiaries operating in the United States and the number operating in foreign countries are given (17 CFR 229.601(b)(21)(ii)). That instruction does not apply to banks, insurance companies, savings and loan associations, or to any subsidiary subject to regulation by another Federal agency. Significant subsidiary is a defined threshold in its own right, and the same Regulation S-X rule sets it with an investment test, an asset test and an income test (17 CFR 210.1-02(w)).
What a Subsidiary Is Not
A subsidiary in this sense is a company. A subsidiary ledger is a record, the detail sitting behind one general ledger control account, and the two share nothing but the word.
A division or a branch is part of the same legal entity, so it has no organizational documents of its own and carries no liability shield of its own. Affiliate is the wider term: an affiliate is a person that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, the person specified (17 CFR 210.1-02(b)). Every subsidiary is an affiliate of its parent. Not every affiliate is a subsidiary.
Common Questions
A company that another company controls, usually by holding most of its voting shares. The controlled company keeps its own name, its own books and its own legal identity, and the controlling company is called the parent or the holding company.
It carries two senses that are easy to collide. As an adjective in ordinary English it means secondary or supporting, as in a subsidiary role. As a noun in company law and accounting it means the controlled company described here, and the ordinary adjective tells you nothing about which companies qualify.
No. Sister companies are two subsidiaries sitting under the same parent, so the relationship between them runs sideways and neither owns the other. A parent and its subsidiary sit in a vertical relationship, with control running from one to the other. Sister companies are still affiliates of each other, because they are under common control.
The term marks a separate legal person that another person controls. The subsidiary contracts in its own name, sues and is sued in its own name, and its parent is not answerable for its acts unless a court pierces the veil. Individual statutes and rules define the term for their own purposes, so the ownership threshold that matters depends on which rule is being applied rather than on the word.
Accountably places trained offshore accountants inside US CPA and EA firms, and a firm whose entity count has outgrown its close calendar can grade that work for itself first through a trial task.
