Equity in Net Assets of Nonconsolidated Affiliates Equity in Net Assets of Nonconsolidated Affiliates
Nonconsolidated affiliates are entities in which we maintain an equity ownership interest and for which we use the equity method of accounting due to our ability to exert significant influence over decisions relating to their operating and financial affairs. Revenue and expenses of our joint ventures are not consolidated into our financial statements; rather, our proportionate share of the earnings of each joint venture is reflected as Equity income (loss) or Automotive and other cost of sales.

The carrying amount of our investments in certain joint ventures exceeded our share of the underlying net assets by $1.9 billion and $4.2 billion at December 31, 2024 and 2023 primarily due to goodwill from the application of fresh-start reporting and the purchase of additional interests in nonconsolidated affiliates.

Impairment Charges Our Automotive China JVs generated an equity loss of $4.4 billion in the year ended December 31, 2024, which includes $2.0 billion of impairments and restructuring-related charges recorded by certain of the China JVs and a $2.1 billion other-than-temporary impairment charge to write down certain of our automotive investments to their fair values. In response to intense competition in a market with significant excess capacity and an increasingly challenging regulatory environment related to emissions, fuel consumption and NEVs, we and our JV partners are restructuring our operations in China. The charges recorded by the China JVs were primarily related to asset impairments associated with plant closures and portfolio optimization actions and the recognition of a valuation allowance on deferred tax assets. As a result of the market challenges and competitive conditions, GM Financial also recorded a $0.3 billion other-than-temporary impairment charge to write down its SAIC-GMAC investment to its fair value.

Fair Value Measurements In performing our impairment testing, we utilize a third-party valuation specialist to assist in determining the fair values of our investments based on valuation techniques using the best available information. The fair values of the investments in the China JVs are estimated based on their discounted cash flows (income approach). We make significant assumptions and estimates about the extent and timing of future cash flows, growth rates, market share and discount rates that represent unobservable, Level 3, inputs into our valuation methodologies. Where available and as appropriate, comparative market multiples are used to corroborate the results of the discounted cash flow method.

The investment balance for SGM, SGM Norsom, SGM DY and SGM DYPT that was tested for impairment was $2.4 billion and the estimated key assumptions utilized in our impairment testing were: 16.5% discount rate; 0.5% long-term growth rate; passenger vehicle industry volumes of 23.3-24.0 million and a market share of 2.0-2.2% in 2024 through 2028. The investment balance for SAIC-GMAC that was tested for impairment was $1.5 billion and the estimated key assumptions utilized in our impairment testing were: 13.0% discount rate; 3.5% long-term growth rate; and alignment with the Automotive China JVs on vehicle volumes and market share.

The discount rate considered various factors including bond yields, cost of equity, risk premiums and tax rates; the terminal values were determined using a growth model that applied an investee's long-term growth rate to its projected cash flows beyond the forecast period; and industry volumes and market share included annual estimates through the forecast period. In addition, minimum operating cash needs that incorporate specific business, economic and regulatory factors giving rise to varying cash needs were estimated. Our fair value estimates assume the achievement of the future financial results
contemplated in our forecasted cash flows which is subject to significant uncertainties. There is no assurance that anticipated financial results will be achieved.
