Equity Method

The equity method is the way a company accounts for an investment in another company when it holds enough of a stake to exert significant influence but not outright control — conventionally a holding of roughly 20 to 50 percent of the other company's voting shares. Under it, the investor first records the investment at cost. Then, each period, it adjusts the carrying value by its proportionate share of the investee's profit or loss, and it reduces the carrying value by any dividends it receives. So if a company owns 30 percent of an associate, it adds 30 percent of the associate's net income to the investment's value and reports that same share as income on its own statement. The investment line moves with the fortunes of the company invested in.

This treatment reflects the economic reality of significant influence. A holder large enough to sway an associate — through board seats, participation in policy, or material transactions — is more than a passive shareholder collecting dividends, so simply recording dividends would understate the relationship. The equity method captures the investor's genuine stake in the associate's performance as it is earned, not only when cash is paid out. It is sometimes called one-line consolidation because the investor's share of the associate shows up in a single investment line on the balance sheet and a single line of income, rather than by combining the two companies' revenues and costs. The associate stays a separate company; only the investor's slice of its results flows through.

The equity method sits in the middle of three treatments that depend on how much of another company you own. Below significant influence — usually under 20 percent — a holder typically uses the cost method or fair-value accounting, recognizing income mainly when dividends are received or when the investment's market value changes, because it has little say in the company. Above control — usually more than 50 percent of the votes — the holder consolidates: it combines the subsidiary's revenues, costs, assets, and liabilities line by line into its own statements, then backs out the portion it does not own as a non-controlling interest. The equity method covers the band between, where there is real influence but not control.

The contrast is sharpest against full consolidation. Consolidation treats a controlled subsidiary as part of the same economic entity, so the parent's revenue and every cost of the subsidiary appear in the group accounts. The equity method does not: it never adds the associate's revenue or costs to the investor's, only the investor's net share of the associate's profit, in that single line. Against the cost method, the difference is recognition timing — the equity method books the investor's share of earnings as they arise, while the cost method waits for dividends. So the same dollar investment can look very different depending on which method the ownership level dictates, which is why the 20 percent and 50 percent guideposts, judged alongside actual influence and control, matter so much.

Applying the equity method well starts with judging the substance of the relationship, not just the percentage. The 20-to-50 percent band is a guideline for significant influence, but the real test is whether the investor can participate in the investee's financial and operating decisions — through board representation, policy input, or material dealings. A holder with 15 percent and a board seat might have significant influence; a holder with 25 percent and no voice might not. Once the method applies, the discipline is to update the carrying value faithfully each period for the share of earnings and for dividends, and to test the investment for impairment if the associate's prospects sour, so the balance does not carry a stale, inflated value.

It also means reading equity-method income for what it is. The share of an associate's profit flows into the investor's earnings, but it is not cash in hand — the cash arrives only as dividends, which can lag or never fully match reported income. So a company can show healthy equity-method earnings while receiving little cash from the associate, a gap worth watching. Analysts often look through the single line to the underlying associate to understand what is really driving it. Used properly, the equity method gives a truthful, proportionate picture of an influential but non-controlling stake — more informative than the cost method, less all-encompassing than consolidation — provided the ownership is classified honestly and the carrying value is kept current.

So called because the investor carries the investment in line with its share of the investee's equity, adjusting the balance for earnings and dividends.
