An associate company is a business in which another company — referred to as the investing company or parent — holds a significant but non-controlling ownership stake, typically between 20% and 50% of the voting shares. The investing company is considered to have significant influence over the associate but does not control it, meaning it can participate in financial and operating policy decisions but cannot dictate them unilaterally. This ownership range and degree of influence triggers specific accounting treatment under international standards: the equity method rather than full consolidation.
The 20% lower boundary is a rebuttable presumption, not an absolute rule. A holding below 20% may still qualify as an associate if the investor can demonstrate significant influence — for example, through board representation, involvement in policy-setting processes, or material intercompany transactions. Conversely, a holding above 20% may not constitute an associate if other shareholders collectively maintain a blocking majority that effectively excludes the investor from any meaningful participation. The existence of significant influence is assessed based on substance over form.
Under IAS 28 (IASB) and ASC 323 (US GAAP), evidence of significant influence typically includes one or more of the following: representation on the associate's board of directors, participation in policy-making processes, material intercompany transactions, interchange of management personnel, or provision of essential technical information.
An investment in an associate is initially recorded at cost on the investor's balance sheet as a non-current asset. Thereafter, the carrying value is adjusted each period to reflect the investor's proportional share of the associate's profits or losses — increasing the carrying value for earnings and reducing it for losses. Dividends received from the associate are not recorded as income; instead, they reduce the carrying value of the investment, because they represent a return of capital already recognized in the investor's book value through prior profit recognition.
The BASE analysis summarizes the mechanics: Ending Balance = Beginning Balance + Share of Equity Income − Dividends Received.
| Relationship | Typical Ownership | Degree of Influence | Accounting Method |
|---|---|---|---|
| Simple investment | Under 20% | None / passive | Fair value through P&L or OCI (IFRS 9 / ASC 321) |
| Associate | 20%–50% | Significant influence; no control | Equity method (IAS 28 / ASC 323) |
| Joint venture | ~50% with partner | Joint control | Equity method (IFRS 11) |
| Subsidiary | Over 50% | Control | Full consolidation (IFRS 10 / ASC 810) |
Berkshire Hathaway's portfolio of minority stakes offers textbook illustrations. Its approximate 17.6% stake in American Express and 26.7% stake in Kraft Heinz are treated as associates because Berkshire exercises significant influence despite not holding a controlling majority. In the technology sector, Apple's historical relationship with Intel before its shift to in-house silicon, and various semiconductor joint ventures between competing firms, have been structured as associates to achieve collaborative supply chain goals without triggering full consolidation of financial results.
