A subsidiary is a company that is owned or controlled by another company, called the parent company or holding company. Control usually comes from holding more than half of the subsidiary’s voting shares, which lets the parent elect its board and direct its strategy. When the parent owns all of the shares, the business is a wholly owned subsidiary. Although the parent controls it, a subsidiary remains a separate legal entity with its own assets, liabilities, contracts and tax obligations.

How a Subsidiary Works

A subsidiary is incorporated or organized in its own right. Many are corporations, and many are formed as limited liability companies. Because it is a separate entity, the subsidiary signs its own contracts, holds its own bank accounts, files its own tax returns where required, and is responsible for its own debts.

As controlling shareholder, the parent votes to elect the subsidiary’s board, and parent executives often sit on it. The subsidiary normally has its own CEO and management team, but the parent has a strong say in who fills those roles and in major decisions such as budgets, dividends to the parent and large investments.

A parent can acquire a subsidiary by buying a controlling stake in an existing company or create one to house a new product line, regional operation or specific asset. Selling a subsidiary means selling its shares, which transfers the whole business, including contracts and liabilities, to the buyer.

Ownership Levels and Accounting Treatment

Ownership largely decides how an investor reports the stake. Under both U.S. GAAP and IFRS the test is control, usually shown by a majority of voting shares.

These percentages are conventional presumptions, not hard rules. A company can control another with less than half the shares (through voting agreements or board appointment rights, for example), and a majority owner can lack control in unusual situations.

Consolidation

A subsidiary usually keeps its own books. The parent combines them with its own and its other subsidiaries’ to produce consolidated financial statements, which present the group as one economic unit. Transactions between group members, such as a sale from parent to subsidiary, are eliminated so the group does not report revenue or profit earned from itself.

Consolidation brings in 100% of a subsidiary’s revenue, expenses, assets and liabilities even when the parent owns less than all of it. The share belonging to outside shareholders appears separately as a noncontrolling interest.

Hypothetical example: ParentCo owns 80% of SubCo, which earns $10 million of net income on $50 million of revenue. ParentCo’s consolidated income statement includes all $50 million of revenue and all $10 million of net income. It then attributes $2 million (20%) to the noncontrolling interest, leaving $8 million for ParentCo’s shareholders. The balance sheet includes SubCo’s full assets and liabilities, with the outside owners’ 20% claim shown within equity as noncontrolling interest.

This matters for analysis. When computing enterprise value, noncontrolling interest is added because the consolidated EBITDA or revenue it is compared with includes 100% of partly owned subsidiaries.

Unconsolidated subsidiaries and associates

An associate’s results are not consolidated. The investor records its stake as one asset and recognizes its share of profit or loss under the equity method. An unconsolidated subsidiary is an owned entity carried as an investment rather than consolidated. For a majority-owned company this should be rare. The U.S. Securities and Exchange Commission has indicated it applies in cases such as bankruptcy, when control rests with someone other than the majority owner.

Why Companies Use Subsidiaries

• Risk containment. As a separate entity, the subsidiary’s creditors and litigants generally have claims against it, not the parent. Film and television producers often place an individual movie or show in its own entity for this reason.
• Smaller commitment than a merger. A controlling stake can require less capital than buying all of a company, and it typically does not need the parent shareholder vote a merger can.
• Synergies and assets. A subsidiary can add a product line, earnings, equipment, property, licenses or distribution.
• Experimentation. A separate entity can test a new structure, manufacturing method or product without reorganizing the core business.
• Tax and regulatory structure. Subsidiaries let groups operate under local law in different countries or meet sector rules. In the U.S., a parent owning at least 80% of a subsidiary’s voting power and value can generally file a consolidated federal tax return with it.
• Easier divestment. A business in its own entity can be sold, spun off or partly listed more cleanly than a division woven into the parent.

Examples of Subsidiaries

U.S. public companies must disclose their significant subsidiaries in SEC filings, usually as an exhibit to the annual report. Berkshire Hathaway’s subsidiaries include GEICO, International Dairy Queen, Clayton Homes, Business Wire and Helzberg Diamonds. Many are held for the long term and run by their own management with the parent’s financial backing.

Alphabet Inc. is the parent of Google and of other separately organized businesses it owns for diversification, revenue and research and development.

Limitations and Drawbacks

• More legal and accounting work. Each entity needs its own filings, books, governance and often audits, and consolidation complicates group reporting.
• Bureaucracy and limits on control. A subsidiary must observe its own corporate formalities, and dealings with the parent may need to be at arm’s length. Minority shareholders also have rights the parent must respect.
• Liability shield has gaps. A parent can still be liable for criminal conduct or wrongdoing by the subsidiary’s management, and courts can “pierce the corporate veil” when a subsidiary is treated as a mere extension of its parent.
• Guarantees. Lenders often ask the parent to guarantee a subsidiary’s loans, bringing that debt risk back to the parent.

Subsidiary vs. Related Terms

• Division: part of the parent itself, not a separate legal entity.
• Associate or affiliate: significant influence but not control. “Affiliate” is also used loosely for any company in the same group.
• Sister companies: subsidiaries controlled by the same parent.
• Holding company: a parent whose main activity is owning subsidiaries rather than running operations.
• Joint venture: an entity controlled jointly by two or more owners, none of which controls it alone.

FAQs

The Bottom Line

Investors reading consolidated statements and companies weighing how to structure a business both need to understand subsidiaries. A subsidiary can contain risk, ease divestment and require less capital than a full merger, but it adds legal and accounting work. Its liability shield also has gaps, since courts can pierce the corporate veil and lenders often demand parent guarantees.
