Equity method Wikipedia
Equity method in accounting is the process of treating equity investments, in associate companies. The investor keeps such equities as an asset. The investor's proportional share of the associate company's net income increases the investment (and a net loss decreases the investment), and proportional payments of dividends decrease it. In the investor’s income statement, the proportional share of the investor’s net income or net loss is reported as a single-line item.
Equity accounting is usually applied where the entity holds 20–50% of voting stock, since this implies significant influence on the decisions of the associate by the holding company. Equity accounting may also be appropriate where the holding falls outside this range and may be inappropriate for some entities within this range depending on the nature of the actual relationship between the investor and investee. The ownership of more than 50% of voting stock creates a subsidiary. Its financial statements consolidate into the parent's. The ownership of less than 20% creates an investment position carried at historic book or fair market value (if available for sale or held for trading) in the investor's balance sheet.
