What Is the Equity Method?
The equity method applies when an investor holds enough of another company to influence its decisions but not enough to control it. Under US GAAP, significant influence is presumed at ownership between 20% and 50% of voting stock, though board seats, technology dependence, or major intercompany transactions can establish influence at lower stakes. Joint ventures are also commonly accounted for this way.
Rather than consolidating the investee line by line, the investor carries a single 'equity method investment' asset on its balance sheet and records a single 'income from equity investees' line on its income statement. Analysts often describe this as one-line consolidation.
How the Accounting Works
The investment starts on the balance sheet at cost. Each period, the carrying value increases by the investor's proportional share of the investee's net income and decreases by any dividends received, since dividends are treated as a return of the investment rather than income. If an investor owns 30% of a company that earns $200 million and pays $50 million in total dividends, the investor books $60 million of equity income and reduces the investment balance by its $15 million dividend share.
Two cash flow adjustments follow from this. Equity income is subtracted in operating cash flow because the cash was never received, while dividends actually collected are added back. If the investment's value falls below carrying value and the decline is other than temporary, the investor must record an impairment.
Why It Matters in Valuation and Interviews
Equity method investments create a consistency problem in multiples. Consolidated EBITDA excludes the investee's operations, yet the market value of the stake is embedded in the company's share price. Analysts therefore subtract the value of equity investments when moving from equity value to enterprise value, mirroring how noncontrolling interest is added on the other side of the bridge.
The topic is a favorite in banking interviews because it tests whether candidates understand the ownership spectrum: below 20% typically means cost or fair value treatment, 20% to 50% triggers the equity method, and majority ownership requires full consolidation. Being able to walk through the journal entries and the enterprise value implications in one coherent answer stands out.
