Definition:Equity method
📒 Equity method is an accounting approach used in insurance group financial statements to recognize an insurer's share of the net income or loss of entities in which it holds significant influence — typically defined as an ownership stake between 20% and 50% — without consolidating the investee's full financial results. In the insurance industry, this method frequently arises when a carrier or holding company maintains strategic minority stakes in other insurers, MGAs, insurtech ventures, or affiliated distribution platforms. Under both IFRS (specifically IAS 28) and US GAAP (ASC 323), equity-method investments are initially recorded at cost and subsequently adjusted to reflect the investor's proportionate share of the investee's earnings, losses, and other comprehensive income.
📐 In practice, an insurer applying the equity method records its initial investment on the balance sheet and then increases or decreases the carrying amount each period by its share of the investee's profit or loss, with dividends received reducing the investment balance. Crucially, the investee's individual assets, liabilities, reserves, and premiums do not appear on the investing insurer's consolidated statements — only a single line item for the investment and a corresponding share of earnings. This distinction matters significantly for regulatory capital calculations: under Solvency II in Europe, for example, the treatment of equity-method investments in calculating the Solvency Capital Requirement differs from the treatment of fully consolidated subsidiaries, and similar distinctions exist under the NAIC's risk-based capital framework in the United States and the C-ROSS regime in China. Impairment testing is also required — if the investee's value declines on a basis that is other-than-temporary, the insurer must write down the investment.
💡 Properly understanding the equity method is essential for analysts, regulators, and investors evaluating an insurance group's financial health, because significant value — and risk — can reside in equity-method investments that appear as a single balance-sheet line. A large reinsurer with minority stakes in several regional carriers, for instance, may have material earnings volatility driven by those investees' underwriting results and investment returns, yet this exposure is far less visible than it would be under full consolidation. Equity research analysts covering insurance groups routinely scrutinize equity-method investments for hidden value or embedded losses. With the adoption of IFRS 17 reshaping how insurance contracts are measured, the interplay between IFRS 17 and IAS 28 has added further complexity to how insurers account for their stakes in other insurance entities.
