| Schedule of Variable Interest Entities | The following table presents our involvement in consolidated and nonconsolidated VIEs in which we hold variable interests. We have excluded certain transactions with nonconsolidated entities from the balances presented in the table below, where our only continuing involvement relates to financial interests obtained through the ordinary course of business, primarily from lending and investing arrangements. For additional detail related to the assets and liabilities of consolidated variable interest entities, refer to our Condensed Consolidated Balance Sheet.
(a)Represents the current unpaid principal balance of outstanding consumer automotive finance receivables and loans within the VIEs. (b)Includes $8.9 billion of assets that were not encumbered by VIE beneficial interests held by third parties at both March 31, 2026, and December 31, 2025. Ally or consolidated affiliates hold the interests in these assets. (c)Includes $131 million and $137 million of liabilities that were not obligations to third-party beneficial interest holders at March 31, 2026, and December 31, 2025, respectively. (d)Includes activity where we sell loans through a pass-through program to a third party. (e)Represents retained notes and certificated residual interests, of which $43 million and $50 million were classified as held-to-maturity securities at March 31, 2026, and December 31, 2025, respectively, and $3 million were classified as other assets at both March 31, 2026, and December 31, 2025. These assets represent our compliance with the risk retention rules under the Dodd-Frank Act, requiring us to retain at least five percent of the credit risk of the assets underlying asset-backed securitizations. (f)Maximum exposure to loss represents the current unpaid principal balance of outstanding loans based on our customary representation and warranty provisions. This measure is based on the unlikely event that all the loans have underwriting defects or other defects that trigger a representation and warranty provision and the collateral supporting the loans are worthless. This required disclosure is not an indication of our expected loss. (g)Amounts are classified as other assets except for $57 million and $56 million classified as equity securities at March 31, 2026, and December 31, 2025, respectively. (h)Amounts are classified as accrued expenses and other liabilities. (i)For certain nonconsolidated affordable housing entities, maximum exposure to loss represents the yield we guaranteed investors through long-term guarantee contracts. The amount disclosed is based on the unlikely event that the yield delivered to investors in the form of LIHTCs and other tax credits is recaptured. For nonconsolidated equity investments, maximum exposure to loss represents our outstanding investment, additional committed capital, and LIHTCs and other tax credits subject to recapture. The amount disclosed is based on the unlikely event that our committed capital is funded, our investments become worthless, and the tax credits previously delivered to us are recaptured. This required disclosure is not an indication of our expected loss.
