Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business, Basis of Presentation, and Changes in Significant Accounting Policies	Description of Business, Basis of Presentation, and Changes in Significant Accounting Policies Ally Financial Inc. (together with its consolidated subsidiaries unless the context otherwise requires, Ally, the Company, we, us, or our) is a financial-services company with the nation’s largest all-digital bank and an industry-leading automotive financing and insurance business, driven by a mission to “Do It Right” and be a relentless ally for customers and communities. The Company serves customers through a full range of online banking services (including deposits, mortgage lending, point-of-sale personal lending and credit-card products) and securities brokerage and investment advisory services. The Company also includes a corporate finance business that offers capital for equity sponsors and middle-market companies. Ally is a Delaware corporation and is registered as a BHC under the BHC Act and an FHC under the GLB Act. Our accounting and reporting policies conform to U.S. GAAP. Additionally, where applicable, the policies conform to the accounting and reporting guidelines prescribed by bank regulatory authorities. Certain reclassifications may have been made to the prior periods’ financial statements and notes to conform to the current period’s presentation, which did not have a material impact on our Condensed Consolidated Financial Statements. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and that affect income and expenses during the reporting period and related disclosures. In developing the estimates and assumptions, management uses all available evidence; however, actual results could differ because of uncertainties associated with estimating the amounts, timing, and likelihood of possible outcomes. Our most significant estimates pertain to the allowance for loan losses, valuations of automotive lease assets and residuals, fair value of financial instruments, and the determination of the provision for income taxes. The Condensed Consolidated Financial Statements at March 31, 2023, and for the three months ended March 31, 2023, and 2022, are unaudited but reflect all adjustments that are, in management’s opinion, necessary for the fair presentation of the results for the interim periods presented. All such adjustments are of a normal recurring nature. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements (and the related Notes) included in our Annual Report on Form 10-K for the year ended December 31, 2022, as filed on February 24, 2023, with the SEC. Significant Accounting Policies Finance Receivables and Loans On January 1, 2023, we implemented ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . This guidance eliminates the concept of TDRs and adds new disclosure requirements related to loan modifications to borrowers experiencing financial difficulty and gross charge-offs. We implemented the ASU on a prospective basis, which results in certain aspects of our accounting policies changing for the current year. For significant accounting policy information related to the accounting and reporting of TDRs, for which comparative period information is presented, refer to Note 1 to the Consolidated Financial Statements in our 2022 Annual Report on Form 10-K. Modifications of Loans with Borrowers Experiencing Financial Difficulty We may provide a modification to a borrower who is experiencing financial difficulty if we believe they have the ability and are willing to repay their loan. The type of modification granted will vary depending on our credit risk management practices, as well as the borrower’s financial condition and the characteristics of the loan, including the unpaid balance, the underlying collateral, and the number or types of previous modifications granted. Modifications that we make subject to these requirements include payment extensions, principal forgiveness, and/or interest rate concessions. These modifications generally reduce the borrower’s periodic payment amount. The following is a description of each of these types of modifications. • Payment extensions — Payment extensions include both payment deferrals and contractual maturity extensions. Deferral arrangements allow borrowers to delay a scheduled loan payment to a later date. Deferred loan payments do not affect the original contractual terms of the loan and the contractual maturity date of the loan remains unchanged. Deferrals also include certain forbearance agreements. Within the commercial loan portfolio, deferrals primarily reflect a deferral of interest payments. Under a contractual maturity extension agreement, the last payment date is extended to a future date, contractually lengthening the remaining term of the original loan. • Principal forgiveness — Under principal forgiveness, the outstanding principal balance of a loan is reduced by a specified amount. Principal forgiveness may occur voluntarily as part of a negotiated agreement with a borrower, or involuntarily through a bankruptcy proceeding. Under these involuntary instances, the bankruptcy court in a Chapter 11 or 13 proceeding may order us to reduce the outstanding principal balance of the loan to a specified amount. • Interest rate concessions — Interest rate concessions adjust the contractual interest rate of the loan to a rate that is not consistent with a market rate for a customer with similar credit risk. • Combination — Combination includes loans that have undergone multiple of the above loan modification types. This primarily includes rewritten loans where we grant an interest rate concession and a contractual maturity extension. Significant judgment is required to determine if a borrower is experiencing financial difficulty. These considerations vary by portfolio class. In all cases, the cumulative impacts of all modifications made within the 12-month period before the current modification are considered at the time of the most recent modification. For consumer loans of all classes, various qualitative factors are used for assessing the financial difficulty of the borrower. These factors include, but are not limited to, the borrower’s default status on any of its debts, bankruptcy, and recent changes in financial circumstances (for instance, loss of employment). For commercial loans of all classes, similar qualitative factors are considered when assessing the financial difficulty of the borrower. In addition to the previously noted factors, consideration is also given to the borrower’s forecasted ability to service the debt in accordance with the contractual terms, possible regulatory actions, and other potential business disruptions (for example, the loss of a significant customer or other revenue stream). In our consumer automotive portfolio class of loans, we also provide extensions or deferrals of payments to borrowers whom we deem to be experiencing only temporary financial difficulty. In these cases, there are limits within our operational policies to minimize the number of times a loan can be extended, as well as limits to the length of each extension, including a cumulative cap over the life of the loan. If these limits are breached, the modification may require disclosure as noted in the following paragraph. Before offering an extension or deferral, we evaluate the capacity of the customer to make the scheduled payments after the deferral period. During the deferral period, we continue to accrue interest on the loan as part of the deferral agreement. We grant these extensions or deferrals when we expect to collect all amounts due including interest accrued at the original contract rate. We do not disclose modifications that result in only an insignificant payment delay. In order to assess whether a payment delay is insignificant, we consider the amount of the modified payments subject to delay in conjunction with the unpaid principal balance or the collateral value of the loan, whether or not the delay is significant with respect to the frequency of payments under the original contract, or the loan’s original expected duration. In the cases where payment extensions cumulatively extend beyond 90 days and are more than 10% of the original contractual term, or where the cumulative payment extension within the 12-month period immediately preceding the current modification is beyond 180 days, we deem the delay in payment to be more than insignificant. The financial impacts of modifications that meet the definition of a modification to borrowers experiencing financial difficulty are reported in the period in which they are identified. Additionally, if such a loan defaults within 12 months of the modification, we are required to disclose the instances of redefault. For the purpose of this disclosure, we have determined that a loan is considered to have redefaulted when the loan meets the requirements for evaluation under our charge-off policy, except for commercial loans where redefault is defined as 90 days past due. Nonaccrual Loans Generally, we recognize loans of all classes as past due when they are 30 days delinquent on making a contractually required payment, and loans are placed on nonaccrual status when principal or interest has been delinquent for at least 90 days, or when full collection is not expected. Interest income recognition is suspended when finance receivables and loans are placed on nonaccrual status. Additionally, amortization of premiums and discounts and deferred fees and costs ceases when finance receivables and loans are placed on nonaccrual status. Exceptions include commercial real estate loans that are placed on nonaccrual status when delinquent for 60 days or when full collection is not probable, if sooner. Additionally, a loan can be returned to accrual status when the loan has been brought fully current, the collection of contractual principal and interest is reasonably assured, and six consecutive months of repayment performance is achieved. In certain cases, if a borrower has been current up to the time of the modification and repayment of the debt subsequent to the modification is reasonably assured, we may choose to continue to accrue interest on the loan. Income Taxes In calculating the provision for interim income taxes, in accordance with ASC 740, Income Taxes , we apply an estimated annual effective tax rate to year-to-date ordinary income. At the end of each interim period, we estimate the effective tax rate expected to be applicable for the full fiscal year. This method differs from that described in Note 1 to the Consolidated Financial Statements in our 2022 Annual Report on Form 10-K, which describes our annual significant income tax accounting policy and related methodology. Refer to Note 1 to the Consolidated Financial Statements in our 2022 Annual Report on Form 10-K regarding additional significant accounting policies. Recently Adopted Accounting Standards Troubled Debt Restructurings and Vintage Disclosures (ASU 2022-02) In March 2022, the FASB issued ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . The purpose of this guidance is twofold. First, the guidance eliminates TDR recognition and measurement guidance that has been deemed no longer necessary under CECL. The guidance also adds a requirement to incorporate current year gross charge-offs by origination year into the vintage tables. With respect to the TDR impacts, under CECL, credit losses for financial assets measured at amortized cost are determined based on the total current expected credit losses over the life of the financial asset or group of financial assets. Therefore, credit losses on financial assets that have been modified as TDRs would have largely been incorporated in the allowance upon initial recognition. Under ASU 2022-02, we will evaluate whether loan modifications previously characterized as TDRs represent a new loan or a continuation of an existing loan in accordance with ASC Topic 310, Receivables . The guidance also added new disclosures that require an entity to provide information related to loan modifications that are made to borrowers that are deemed to be in financial difficulty. We adopted the ASU on January 1, 2023, on a prospective basis. The impact of these amendments was not material. Recently Issued Accounting Standards Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (ASU 2022-03) In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions . The purpose of this guidance is to clarify that a contractual restriction on the ability to sell an equity security is not considered part of the unit of account of the equity security, and therefore should not be considered when measuring the equity security’s fair value. Additionally, an entity cannot separately recognize and measure a contractual-sale restriction. This guidance also adds specific disclosures related to equity securities that are subject to contractual-sale restrictions, including (1) the fair value of equity securities subject to contractual sale restrictions reflected in the balance sheet, (2) the nature and remaining duration of the restrictions, and (3) the circumstances that could cause a lapse in the restrictions. The amendments are effective on January 1, 2024, with early adoption permitted. The amendments must be applied using a prospective approach with any adjustments from the adoption of the amendments recognized in earnings and disclosed upon adoption. Management does not expect the impact of these amendments to be material. Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (ASU 2023-02) In March 2023, the FASB issued ASU 2023-02, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method . The purpose of this guidance is to expand the use of the proportional amortization method to certain tax equity investments made primarily for the purpose of receiving income tax credits and other income tax benefits. In order to qualify for the proportional amortization method, the following five conditions must be met: (1) it is probable that the income tax credits allocable to the tax equity investor will be available, (2) the tax equity investor does not have the ability to exercise significant influence over the operating and financial policies of the underlying project, (3) substantially all of the projected benefits are from income tax credits and other income tax benefits, (4) the tax equity investor’s projected yield is based solely on the cash flows from the income tax credits and other income tax benefits is positive, and (5) the tax equity investor is a limited liability investor in the limited liability entity for both legal and tax purposes, and the tax equity investor’s liability is limited to its capital investment. Selecting the proportional amortization method will be an accounting policy election that must be applied on a tax-credit-program-by-tax-credit-program basis rather than at the entity level or to individual investments. Additionally, in order to apply the proportional amortization method to qualifying investments, an entity must use the flow-through method when accounting for the receipt of the investment tax credits. This guidance also adds disclosure requirements related to tax credit programs where the proportional amortization method has been elected. The amendments are effective on January 1, 2024, with early adoption permitted. The amendments must be applied using either a modified retrospective or retrospective approach with any adjustments from the adoption of the amendments recognized in retained earnings and disclosed upon adoption. In the event that we elect to apply the proportional amortization method to any qualifying programs upon adoption, management is still assessing the total impacts of these amendments, but does not expect the impact of these amendments to be material.

As part of our Insurance operations, we recognize revenue from insurance contracts, which are addressed by other U.S. GAAP topics and are not included in the scope of this standard. Certain noninsurance contracts within our Insurance operations, including VSCs, GAP contracts, and VMCs, are included in the scope of this standard. All revenue associated with noninsurance contracts is recognized over the contract term on a basis proportionate to the anticipated cost emergence. Further, commissions and sales expense incurred to obtain these contracts are amortized over the terms of the related policies and service contracts on the same basis as premiums and service revenue are earned, and all advertising costs are recognized as expense when incurred. The following table presents a disaggregated view of our revenue from contracts with customers. For further information regarding our revenue recognition policies and details about the nature of our respective revenue streams, refer to Note 1 and Note 3 to the Consolidated Financial Statements in our 2022 Annual Report on Form 10-K.

During the three months ended March 31, 2023, and 2022, management determined that there were no expected credit losses for securities in an unrealized loss position. This analysis considered a variety of factors including, but not limited to, performance indicators of the issuer, default rates, industry analyst reports, credit ratings, and other relevant information, which indicated that contractual cash flows are expected to occur. As a result of this evaluation, management determined that no credit reserves were required at March 31, 2023, or December 31, 2022.

Credit Quality Indicators We evaluate the credit quality of our consumer loan portfolio based on the aging status of the loan and by payment activity. Loan delinquency reporting is generally based upon borrower payment activity, relative to the contractual terms of the loan.

We use the following definitions for risk rankings below Pass. • Special mention — Loans that have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or the institution’s credit position at some future date. • Substandard — Loans that are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. These loans have a well-defined weakness or weakness that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. • Doubtful — Loans that have all the weaknesses inherent in those classified as substandard, with the additional characteristic that the weaknesses make collection or liquidation in full, based on the basis of currently existing facts, conditions, and values, highly questionable and improbable. • Loss — Loans that are considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the asset has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be effected in the future. The regulatory risk classification utilized is influenced by internal credit risk ratings, which are based on a variety of factors. A borrower’s internal credit risk rating is updated at least annually, and more frequently when a borrower’s credit profile changes, including when we become aware of potential credit deterioration. The following tables present the amortized cost basis of our commercial finance receivables and loans by credit quality indicator based on risk rating and origination year.

Leasing

Leasing	3 Months Ended
	Mar. 31, 2023
Leases [Abstract]
Leasing	Leasing Ally as the Lessee We have operating leases for certain of our corporate facilities, which have remaining lease terms of 5 months to 8 years. Most of the property leases have fixed payment terms with annual fixed-escalation clauses and include options to extend or terminate the lease. We do not include these term extensions or termination provisions in our estimates of the lease term if we do not consider it reasonably certain that the options will be exercised. We also have operating leases for a fleet of vehicles that is used by our sales force for business purposes, with noncancelable lease terms of 367 days. Thereafter, the leases are month-to-month, up to a maximum of 48 months from inception. During the three months ended March 31, 2023, and March 31, 2022, we paid $8 million and $10 million, respectively, in cash for amounts included in the measurement of lease liabilities. These amounts are included in net cash provided by operating activities in the Condensed Consolidated Statement of Cash Flows. During the three months ended March 31, 2022, we obtained $12 million of ROU assets in exchange for new lease liabilities. As of March 31, 2023, the weighted-average remaining lease term of our operating lease portfolio was 5 years, and the weighted-average discount rate was 2.59%, compared to 5 years and 2.57% as of December 31, 2022. The following table presents future minimum rental payments we are required to make under operating leases that have commenced as of March 31, 2023, and that have noncancelable lease terms expiring after March 31, 2023.

Upon closing the transaction, the lease ROU asset and liability were derecognized and new fixed assets totaling approximately $44 million were recognized as property and equipment at cost within other assets of the Condensed Consolidated Balance Sheet. The following table details the components of total net operating lease expense. Three months ended March 31, ($ in millions) 2023 2022 Operating lease expense $ 7 $ 8 Variable lease expense 1 1 Total lease expense, net (a) $ 8 $ 9 (a) Included in other operating expenses in our Condensed Consolidated Statement of Comprehensive Income. Ally as the Lessor Investment in Operating Leases We purchase consumer operating lease contracts and the associated vehicles from dealerships after those contracts are executed by the dealers and the consumers. The amount we pay a dealer for an operating lease contract is based on the negotiated price for the vehicle less vehicle trade-in, down payment from the consumer, and available automotive manufacturer incentives. Under the operating lease, the consumer is obligated to make payments in amounts equal to the amount by which the negotiated purchase price of the vehicle (less any trade-in value, down payment, or available manufacturer incentives) exceeds the contract residual value (including residual support) of the vehicle at lease termination, plus operating lease rental charges. The customer can terminate the lease at any point after commencement, subject to additional charges and fees. Both the consumer and the dealership have the option to purchase the vehicle at the end of the lease term, which generally range from 24 to 60 months, at the residual value of the vehicle, however it is not reasonably certain this option will be exercised and accordingly our consumer leases are classified as operating leases. In addition to the charges described above, the consumer is generally responsible for certain charges related to excess mileage or excessive wear and tear on the vehicle. These charges are deemed variable lease payments and, as these payments are not based on a rate or index, they are recognized as net depreciation expense on operating lease assets in our Condensed Consolidated Statement of Comprehensive Income as incurred. When we acquire a consumer operating lease, we assume ownership of the vehicle from the dealer. We require that property damage, bodily injury, collision, and comprehensive insurance be obtained by the lessee on all consumer operating leases. Neither the consumer nor the dealer is responsible for the value of the vehicle at the time of lease termination. When vehicles are not purchased by customers or the receiving dealer at scheduled lease termination, the vehicle is returned to us for remarketing. We generally bear the risk of loss to the extent the value of a leased vehicle upon remarketing is below the expected residual value. At termination, our actual sales proceeds from remarketing the vehicle may be higher or lower than the estimated residual value resulting in a gain or loss on remarketing, which is included in net depreciation expense on operating lease assets in our Condensed Consolidated Statement of Comprehensive Income. Excessive mileage or excessive wear and tear on the vehicle during the lease may impact the sales proceeds received upon remarketing. As of March 31, 2023, and December 31, 2022, consumer operating leases with a carrying value, net of accumulated depreciation, of $43 million and $56 million, respectively, were covered by a residual value guarantee of 15% of the manufacturer’s suggested retail price. The following table details our investment in operating leases.

Depreciation expense on operating lease assets includes net remarketing gains recognized on the sale of operating lease assets. The following table summarizes the components of depreciation expense on operating lease assets.

Finance Leases In our Automotive Finance operations, we also hold automotive leases that require finance lease treatment as prescribed by ASC Topic 842, Leases . Our total gross investment in finance leases, which is included in finance receivables and loans, net, on our Condensed Consolidated Balance Sheet was $499 million and $481 million as of March 31, 2023, and December 31, 2022, respectively.

Leasing	Leasing Ally as the Lessee We have operating leases for certain of our corporate facilities, which have remaining lease terms of 5 months to 8 years. Most of the property leases have fixed payment terms with annual fixed-escalation clauses and include options to extend or terminate the lease. We do not include these term extensions or termination provisions in our estimates of the lease term if we do not consider it reasonably certain that the options will be exercised. We also have operating leases for a fleet of vehicles that is used by our sales force for business purposes, with noncancelable lease terms of 367 days. Thereafter, the leases are month-to-month, up to a maximum of 48 months from inception. During the three months ended March 31, 2023, and March 31, 2022, we paid $8 million and $10 million, respectively, in cash for amounts included in the measurement of lease liabilities. These amounts are included in net cash provided by operating activities in the Condensed Consolidated Statement of Cash Flows. During the three months ended March 31, 2022, we obtained $12 million of ROU assets in exchange for new lease liabilities. As of March 31, 2023, the weighted-average remaining lease term of our operating lease portfolio was 5 years, and the weighted-average discount rate was 2.59%, compared to 5 years and 2.57% as of December 31, 2022. The following table presents future minimum rental payments we are required to make under operating leases that have commenced as of March 31, 2023, and that have noncancelable lease terms expiring after March 31, 2023.

Ally as the Lessor Investment in Operating Leases We purchase consumer operating lease contracts and the associated vehicles from dealerships after those contracts are executed by the dealers and the consumers. The amount we pay a dealer for an operating lease contract is based on the negotiated price for the vehicle less vehicle trade-in, down payment from the consumer, and available automotive manufacturer incentives. Under the operating lease, the consumer is obligated to make payments in amounts equal to the amount by which the negotiated purchase price of the vehicle (less any trade-in value, down payment, or available manufacturer incentives) exceeds the contract residual value (including residual support) of the vehicle at lease termination, plus operating lease rental charges. The customer can terminate the lease at any point after commencement, subject to additional charges and fees. Both the consumer and the dealership have the option to purchase the vehicle at the end of the lease term, which generally range from 24 to 60 months, at the residual value of the vehicle, however it is not reasonably certain this option will be exercised and accordingly our consumer leases are classified as operating leases. In addition to the charges described above, the consumer is generally responsible for certain charges related to excess mileage or excessive wear and tear on the vehicle. These charges are deemed variable lease payments and, as these payments are not based on a rate or index, they are recognized as net depreciation expense on operating lease assets in our Condensed Consolidated Statement of Comprehensive Income as incurred. When we acquire a consumer operating lease, we assume ownership of the vehicle from the dealer. We require that property damage, bodily injury, collision, and comprehensive insurance be obtained by the lessee on all consumer operating leases. Neither the consumer nor the dealer is responsible for the value of the vehicle at the time of lease termination. When vehicles are not purchased by customers or the receiving dealer at scheduled lease termination, the vehicle is returned to us for remarketing. We generally bear the risk of loss to the extent the value of a leased vehicle upon remarketing is below the expected residual value. At termination, our actual sales proceeds from remarketing the vehicle may be higher or lower than the estimated residual value resulting in a gain or loss on remarketing, which is included in net depreciation expense on operating lease assets in our Condensed Consolidated Statement of Comprehensive Income. Excessive mileage or excessive wear and tear on the vehicle during the lease may impact the sales proceeds received upon remarketing. As of March 31, 2023, and December 31, 2022, consumer operating leases with a carrying value, net of accumulated depreciation, of $43 million and $56 million, respectively, were covered by a residual value guarantee of 15% of the manufacturer’s suggested retail price.

Securitizations And Variable Interest Entities [Abstract]
Securitizations and Variable Interest Entities	Securitizations and Variable Interest Entities We securitize, transfer, and service consumer automotive loans. We often securitize these loans (also referred to as financial assets) using SPEs. An SPE is a legal entity that is designed to fulfill a specified limited need of the sponsor. Our principal use of SPEs is to obtain liquidity by securitizing certain of our financial assets. SPEs are often VIEs and may or may not be included on our Condensed Consolidated Balance Sheet. Additionally, we opportunistically sell consumer automotive and credit card whole-loans to SPEs where we have a continuing involvement. VIEs are legal entities that either have an insufficient amount of equity at risk for the entity to finance its activities without additional subordinated financial support or, as a group, the holders of the equity investment at risk lack the ability to control the entity’s activities that most significantly impact economic performance through voting or similar rights, or do not have the obligation to absorb the expected losses or the right to receive expected residual returns of the entity. The VIEs included on the Condensed Consolidated Balance Sheet represent SPEs where we are deemed to be the primary beneficiary, primarily due to our servicing activities and our beneficial interests in the VIE that could be potentially significant. The nature, purpose, and activities of nonconsolidated SPEs are similar to those of our consolidated SPEs with the primary difference being the nature and extent of our continuing involvement. For nonconsolidated SPEs, the transferred financial assets are removed from our balance sheet provided the conditions for sale accounting are met. The financial assets obtained from the sale are primarily reported as cash or retained interests (if applicable). Liabilities incurred as part of these sales, are recorded at fair value at the time of sale and are reported as accrued expenses and other liabilities on our Condensed Consolidated Balance Sheet. Upon the sale of the loans, we recognize a gain or loss on sale for the difference between the assets recognized, the assets derecognized, and the liabilities recognized as part of the transaction. With respect to our ongoing right to service the assets we sell, the servicing fee we receive represents adequate compensation, and consequently, we do not recognize a servicing asset or liability. The pretax gain on sales of financial assets into nonconsolidated VIEs was $1 million for the three months ended March 31, 2023. We had no pretax gains or losses on sales of financial assets into nonconsolidated VIEs during the three months ended March 31, 2022. We provide long-term guarantee contracts to investors in certain nonconsolidated affordable housing entities and have extended a line of credit to provide liquidity. Since we do not have control over the entities or the power to make decisions, we do not consolidate the entities and our involvement is limited to the guarantee and the line of credit. We are involved with various other nonconsolidated equity investments, including affordable housing entities and venture capital funds and loan funds. We do not consolidate these entities and our involvement is limited to our outstanding investment, additional capital committed to these funds plus any previously recognized low-income housing tax credits that are subject to recapture. Refer to Note 1 and Note 11 to the Consolidated Financial Statements in our 2022 Annual Report on Form 10-K for further description of our securitization activities and our involvement with VIEs. 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 the Condensed Consolidated Balance Sheet.

(b) Includes $10.4 billion and $10.6 billion of assets that were not encumbered by VIE beneficial interests held by third parties at March 31, 2023, and December 31, 2022, respectively. Ally or consolidated affiliates hold the interests in these assets. (c) Includes $111 million and $113 million of liabilities that were not obligations to third-party beneficial interest holders at March 31, 2023, and December 31, 2022, respectively. (d) 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. (e) Represents balances from Ally Credit Card. (f) Amounts are classified as other assets except for $41 million and $38 million classified as equity securities at March 31, 2023, and December 31, 2022, respectively. (g) Amounts are classified as accrued expenses and other liabilities. (h) 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 low-income tax housing credits is recaptured. For nonconsolidated equity investments, maximum exposure to loss represents our outstanding investment, additional committed capital, and low-income housing 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.

We periodically enter into term repurchase agreements—short-term borrowing agreements in which we sell securities to one or more investors while simultaneously committing to repurchase them at a specified future date, at the stated price plus accrued interest. As of March 31, 2023, the securities sold under agreements to repurchase consisted of $755 million of agency mortgage-backed residential debt securities, of which $493 million are set to mature within 30 days, and $262 million are set to mature within 31 to 60 days. Refer to Note 6 and Note 21 for further details. The primary risk associated with these repurchase agreements is that the counterparty will be unable to perform under the terms of the contract. As the borrower, we are exposed to the excess market value of the securities pledged over the amount borrowed. Daily mark-to-market collateral management is designed to limit this risk to the initial margin. However, should a counterparty declare bankruptcy or become insolvent, we may incur additional delays and costs. In some instances, we may place or receive cash collateral with counterparties under collateral arrangements associated with our repurchase agreements. At March 31, 2023, we placed cash collateral of $4 million subsequent to the execution of the repurchase agreements, and we did not receive any collateral. At December 31, 2022, we placed cash collateral of $1 million subsequent to the execution of the repurchase agreements, and we did not receive any collateral.

Regulatory Capital and Other Regulatory Matters	3 Months Ended

Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
Regulatory Capital and Other Regulatory Matters	Regulatory Capital and Other Regulatory Matters Ally is subject to enhanced prudential standards that have been established by the FRB under the Dodd-Frank Act, as amended by the EGRRCP Act and as applied to Category IV firms under the Tailoring Rules. As a Category IV firm, Ally is (1) subject to supervisory stress testing on a two-year cycle, (2) required to submit an annual capital plan to the FRB, (3) exempted from company-run capital stress testing requirements, (4) required to maintain a buffer of unencumbered highly liquid assets to meet projected net stressed cash outflows over a 30-day planning horizon, (5) exempted from the requirements of the LCR and the net stable funding ratio (provided that our average wSTWF continues to remain under $50 billion), and (6) exempted from the requirements of the supplementary leverage ratio, the countercyclical capital buffer, and single-counterparty credit limits. Even so, we are subject to rules enabling the FRB to conduct supervisory stress testing on a more or less frequent basis based on our financial condition, size, complexity, risk profile, scope of operations, or activities or based on risks to the U.S. economy. Further, we are subject to rules requiring the resubmission of our capital plan if we determine that there has been or will be a material change in our risk profile, financial condition, or corporate structure since we last submitted the capital plan or if the FRB determines that (a) our capital plan is incomplete or our capital plan or internal capital adequacy process contains material weaknesses, (b) there has been, or will likely be, a material change in our risk profile (including a material change in our business strategy or any risk exposure), financial condition, or corporate structure, or (c) the BHC stress scenario(s) are not appropriate for our business model and portfolios, or changes in the financial markets or the macroeconomic outlook that could have a material impact on our risk profile and financial condition require the use of updated scenarios. While a resubmission is pending, without prior approval of the FRB, we would generally be prohibited from paying dividends, repurchasing our common stock, or making other capital distributions. In addition, to satisfy the FRB in its review of our capital plan, we may be required to further cease or limit these capital distributions or to issue capital instruments that could be dilutive to stockholders. The FRB also may prevent us from maintaining or expanding lending or other business activities. Basel Capital Framework The FRB and other U.S. banking agencies have adopted risk-based and leverage capital rules that establish minimum capital-to-asset ratios for BHCs, like Ally, and depository institutions, like Ally Bank. The risk-based capital ratios are based on a banking organization’s RWAs, which are generally determined under the standardized approach applicable to Ally and Ally Bank by (1) assigning on-balance-sheet exposures to broad risk-weight categories according to the counterparty or, if relevant, the guarantor or collateral (with higher risk weights assigned to categories of exposures perceived as representing greater risk), and (2) multiplying off-balance-sheet exposures by specified credit conversion factors to calculate credit equivalent amounts and assigning those credit equivalent amounts to the relevant risk-weight categories. The leverage ratio, in contrast, is based on an institution’s average unweighted on-balance-sheet exposures. Under U.S. Basel III, Ally and Ally Bank must maintain a minimum Common Equity Tier 1 risk-based capital ratio of 4.5%, a minimum Tier 1 risk-based capital ratio of 6%, and a minimum total risk-based capital ratio of 8%. On top of the minimum risk-based capital ratios, Ally and Ally Bank are subject to a capital conservation buffer requirement, which must be satisfied entirely with capital that qualifies as Common Equity Tier 1 capital. Failure to maintain more than the full amount of the capital conservation buffer requirement would result in automatic restrictions on the ability of Ally and Ally Bank to make capital distributions, including dividend payments and stock repurchases and redemptions, and to pay discretionary bonuses to executive officers. U.S. Basel III also subjects Ally and Ally Bank to a minimum Tier 1 leverage ratio of 4%. While the capital conservation buffer requirement for Ally Bank is fixed at 2.5% of RWAs, the capital conservation buffer requirement for a Category IV firm like Ally is equal to its stress capital buffer requirement. The stress capital buffer requirement for Ally, in turn, is the greater of 2.5% and the result of the following calculation: (1) the difference between Ally’s starting and minimum projected Common Equity Tier 1 capital ratios under the severely adverse scenario in the supervisory stress test, plus (2) the sum of the dollar amount of Ally’s planned common stock dividends for each of the fourth through seventh quarters of its nine-quarter capital planning horizon, as a percentage of RWAs. As of March 31, 2023, the stress capital buffer requirement for Ally was 2.5%. Ally and Ally Bank are subject to the U.S. Basel III standardized approach for counterparty credit risk but not to the U.S. Basel III advanced approaches for credit risk or operational risk. Ally is also not subject to the U.S. market-risk capital rule, which applies only to banking organizations with significant trading assets and liabilities. Since Ally and Ally Bank are not subject to the advanced approaches risk-based capital rules, we elected to apply a one-time option to exclude most components of accumulated other comprehensive income from regulatory capital. As of March 31, 2023, and December 31, 2022, Ally had $3.8 billion and $4.1 billion of accumulated other comprehensive losses, net of applicable income taxes, that were excluded from Common Equity Tier 1 capital. Refer to Note 15 for additional details about our accumulated other comprehensive loss. Failure to satisfy regulatory-capital requirements could result in significant sanctions—such as bars or other limits on capital distributions and discretionary bonuses to executive officers, limitations on acquisitions and new activities, restrictions on our acceptance of brokered deposits, a loss of our status as an FHC, or informal or formal enforcement and other supervisory actions—and could have a significant adverse effect on the Consolidated Financial Statements or the business, results of operations, financial condition, or prospects of Ally and Ally Bank. The risk-based capital ratios and the Tier 1 leverage ratio play a central role in PCA, which is an enforcement framework used by the U.S. banking agencies to constrain the activities of depository institutions based on their levels of regulatory capital. Five categories have been established using thresholds for the Common Equity Tier 1 risk-based capital ratio, the Tier 1 risk-based capital ratio, the total risk-based capital ratio, and the Tier 1 leverage ratio: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized. FDICIA generally prohibits a depository institution from making any capital distribution, including any payment of a cash dividend or a management fee to its BHC, if the depository institution would become undercapitalized after the distribution. An undercapitalized institution is also subject to growth limitations and must submit and fulfill a capital restoration plan. Although BHCs are not subject to the PCA framework, the FRB is empowered to compel a BHC to take measures—such as the execution of financial or performance guarantees—when PCA is required in connection with one of its depository-institution subsidiaries. At both March 31, 2023, and December 31, 2022, Ally Bank met the capital ratios required to be well capitalized under the PCA framework. Under FDICIA and the PCA framework, insured depository institutions such as Ally Bank must be well capitalized or, with a waiver from the FDIC, adequately capitalized in order to accept brokered deposits, and even adequately capitalized institutions are subject to some restrictions on the rates they may offer for brokered deposits. Brokered deposits totaled $13.8 billion at March 31, 2023, which represented 9.0% of Ally Bank’s total deposits. The following table summarizes our capital ratios under U.S. Basel III. March 31, 2023 December 31, 2022 Required minimum (a) Well-capitalized minimum ($ in millions) Amount Ratio Amount Ratio Capital ratios Common Equity Tier 1 (to risk-weighted assets) Ally Financial Inc. $ 14,540 9.23 % $ 14,592 9.27 % 4.50 % (b) Ally Bank 17,121 11.43 17,011 11.38 4.50 6.50 % Tier 1 (to risk-weighted assets) Ally Financial Inc. $ 16,803 10.66 % $ 16,867 10.72 % 6.00 % 6.00 % Ally Bank 17,121 11.43 17,011 11.38 6.00 8.00 Total (to risk-weighted assets) Ally Financial Inc. $ 19,626 12.46 % $ 19,209 12.21 % 8.00 % 10.00 % Ally Bank 19,007 12.69 18,888 12.64 8.00 10.00 Tier 1 leverage (to adjusted quarterly average assets) (c) Ally Financial Inc. $ 16,803 8.54 % $ 16,867 8.65 % 4.00 % (b) Ally Bank 17,121 9.18 17,011 9.23 4.00 5.00 % (a) In addition to the minimum risk-based capital requirements for the Common Equity Tier 1 capital, Tier 1 capital, and total capital ratios, Ally and Ally Bank were required to maintain a minimum capital conservation buffer of 2.5% at both March 31, 2023, and December 31, 2022. (b) Currently, there is no ratio component for determining whether a BHC is “well-capitalized.” (c) Federal regulatory reporting guidelines require the calculation of adjusted quarterly average assets using a daily average methodology. On January 1, 2020, we adopted CECL. Refer to Note 1 to the Consolidated Financial Statements in our 2022 Annual Report on Form 10-K for additional information about our allowance for loan losses accounting policy. Under a rule finalized by the FRB and other U.S. banking agencies in 2020, we delayed recognizing the estimated impact of CECL on regulatory capital until after a two-year deferral period, which for us extended through December 31, 2021. Beginning on January 1, 2022, we were required to phase in 25% of the previously deferred estimated capital impact of CECL, with an additional 25% to be phased in at the beginning of each subsequent year until fully phased in by the first quarter of 2025. The estimated impact of CECL on regulatory capital that we deferred and began phasing in on January 1, 2022, is generally calculated as the entire day-one impact at adoption plus 25% of the subsequent change in allowance during the two-year deferral period. As of March 31, 2023, the total deferred impact on Common Equity Tier 1 capital related to our adoption of CECL was $591 million. In December 2017, the Basel Committee approved revisions to the global Basel III capital framework (commonly known as the Basel III endgame or as Basel IV), many of which—if adopted in the United States—could heighten regulatory capital standards. While these revisions were planned for implementation by member countries by January 1, 2023, the U.S. banking agencies have yet to propose rules to do so. At this time, how the revisions will be harmonized and finalized in the United States remains unclear, although officials of the U.S. banking agencies have indicated that regulatory capital standards are expected to become more exacting. In addition, in the wake of the failures of SVB and Signature, President Biden on March 30, 2023, urged the U.S. banking agencies to roll back many of the Tailoring Rules for Category IV firms like Ally, including by (1) imposing regulatory capital standards currently applicable to the largest banking organizations, such as the minimum total-loss absorbing capacity (TLAC) requirement and the inclusion of accumulated other comprehensive income and loss in regulatory capital, (2) reinstating the LCR and requiring more rigorous liquidity stress testing, (3) returning to supervisory stress testing on an annual cycle, and (4) resuming resolution planning for Ally and its significant legal entities under the U.S. Bankruptcy Code and other applicable insolvency laws. On April 28, 2023, in a statement accompanying the review of the FRB’s supervision and regulation of SVB, FRB Vice Chair for Supervision Barr highlighted a plan to revisit the Tailoring Rules and develop stronger capital, liquidity, stress-testing, and other standards for Category IV firms like Ally. Capital Planning and Stress Tests Under the Tailoring Rules, we are generally subject to supervisory stress testing on a two-year cycle and exempted from mandated company-run capital stress testing requirements. We are also required to submit an annual capital plan to the FRB. Our annual capital plan must include an assessment of our expected uses and sources of capital and a description of all planned capital actions over a nine-quarter planning horizon, including any issuance of a debt or equity capital instrument, any dividend or other capital distribution, and any similar action that the FRB determines could have an impact on our capital. The plan must also include a detailed description of our process for assessing capital adequacy, including a discussion of how we, under expected and stressful conditions, will maintain capital commensurate with our risks and above the minimum regulatory capital ratios, will serve as a source of strength to Ally Bank, and will maintain sufficient capital to continue our operations by maintaining ready access to funding, meeting our obligations to creditors and other counterparties, and continuing to serve as a credit intermediary. The Tailoring Rules align capital planning, supervisory stress testing, and stress capital buffer requirements for large banking organizations like Ally. As a Category IV firm, Ally is expected to have the ability to elect to participate in the supervisory stress test—and receive a correspondingly updated stress capital buffer requirement—in a year in which Ally would not generally be subject to the supervisory stress test. Refer to the section titled Basel Capital Framework above for further discussion about our stress capital buffer requirements. During a year in which Ally does not undergo a supervisory stress test, we would receive an updated stress capital buffer requirement only to reflect our updated planned common-stock dividends. Ally was subject to the 2022 supervisory stress test and did not elect to participate in the 2023 supervisory stress test. On January 10, 2022, our Board authorized a stock-repurchase program, permitting us to repurchase up to $2.0 billion of our common stock from time to time from the first quarter of 2022 through the fourth quarter of 2022 subject to restrictions imposed by the FRB, and an increase in our cash dividend on common stock from $0.25 per share for the fourth quarter of 2021 to $0.30 per share for the first quarter of 2022. During the year ended December 31, 2022, we repurchased $1.65 billion of common stock under our stock-repurchase program. Since the commencement of our initial stock-repurchase program in the third quarter of 2016, we have reduced the number of outstanding shares of our common stock by 38%, from 484 million as of June 30, 2016, to 301 million as of March 31, 2023. At this time, the Board has not authorized a stock-repurchase program for 2023. We submitted our 2022 capital plan to the FRB on April 5, 2022. Ally received an updated preliminary stress capital buffer requirement from the FRB in June 2022, which was determined to be 2.5% and reflected a decline of 100 basis points relative to our prior requirement. The updated 2.5% stress capital buffer requirement was finalized in August 2022 and became effective on October 1, 2022. In February 2023, we accessed the unsecured debt capital markets and issued $500 million of additional subordinated notes, which qualify as Tier 2 capital for Ally under U.S. Basel III. We submitted our 2023 capital plan to the FRB on April 5, 2023. Our ability to make capital distributions, including our ability to pay dividends or repurchase shares of our common stock, will continue to be subject to the FRB’s review and our internal governance requirements, including approval by our Board. The amount and size of any future dividends and share repurchases also will be subject to various factors, including Ally’s capital and liquidity positions, accounting and regulatory considerations (including any restrictions that may be imposed by the FRB), the taxation of share repurchases, financial and operational performance, alternative uses of capital, common-stock price, and general market conditions, and may be extended, modified, or discontinued at any time. The following table presents information related to our common stock and distributions to our common stockholders.

Derivative Instruments and Hedg

Derivative Instruments and Hedging Activities	3 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities We enter into derivative instruments, which may include interest rate swaps, foreign-currency forwards, equity options, and interest rate options, in connection with our risk-management activities. Our primary objective for using derivative financial instruments is to manage interest rate risk associated with our fixed-rate and variable-rate assets and liabilities, foreign exchange risks related to our net investments in foreign subsidiaries, as well as foreign-currency denominated assets and liabilities, and other market risks related to our investment portfolio. Interest Rate Risk We monitor our mix of fixed-rate and variable-rate assets and liabilities and may enter into interest rate swaps, forwards, and options to achieve our desired mix of fixed-rate and variable-rate assets and liabilities. We execute these trades to modify our exposure to interest rate risk by converting certain fixed-rate instruments to a variable-rate and certain variable-rate instruments to a fixed-rate. We use a mix of both derivatives that qualify for hedge accounting treatment and economic hedges that do not qualify for hedge accounting treatment. Derivatives qualifying for hedge accounting treatment can include receive-fixed swaps designated as fair value hedges of specific fixed-rate unsecured debt obligations, receive-fixed swaps designated as fair value hedges of specific fixed-rate FHLB advances, pay-fixed swaps designated as fair value hedges of securities within our available-for-sale portfolio, and pay-fixed swaps designated as fair value hedges of fixed-rate held-for-investment consumer automotive loan assets. Other derivatives qualifying for hedge accounting consist of interest rate floor contracts designated as cash flow hedges of the expected future cash flows in the form of interest receipts on a portion of our dealer floorplan commercial loans. We have the ability to execute economic hedges, which could consist of interest rate swaps, interest rate caps, forwards, and options to mitigate interest rate risk. We also enter into interest rate lock commitments and forward commitments that are executed as part of our mortgage business that meet the accounting definition of a derivative. Foreign Exchange Risk We enter into derivative financial instrument contracts to mitigate the risk associated with variability in cash flows related to our various foreign-currency exposures. We enter into foreign-currency forwards with external counterparties as net investment hedges of foreign exchange exposure on our investment in foreign subsidiaries. Our equity is impacted by the cumulative translation adjustments resulting from the translation of foreign subsidiary results; this impact is reflected in our accumulated other comprehensive income. We also periodically enter into foreign-currency forwards to economically hedge any foreign-denominated debt, centralized lending, and foreign-denominated third-party loans. These foreign-currency forwards used as economic hedges are recorded at fair value with changes recorded as income or expense offsetting the gains and losses on the associated foreign-currency transactions. Investment Risk We enter into equity options to mitigate the risk associated with our exposure to the equity markets. Credit Risk We enter into various retail automotive-loan purchase agreements with certain counterparties. As part of those agreements, we may withhold a portion of the purchase price from the counterparty and be required to pay the counterparty all or part of the amount withheld at agreed upon measurement dates and determinable amounts if actual credit performance of the acquired loans on the measurement date is better than or equal to what was estimated at the time of acquisition. Based upon these terms, these contracts meet the accounting definition of a derivative. Counterparty Credit Risk Derivative financial instruments contain an element of credit risk if counterparties are unable to meet the terms of the agreements. Credit risk associated with derivative financial instruments is measured as the net replacement cost should the counterparties that owe us under the contract completely fail to perform under the terms of those contracts, assuming no recoveries of underlying collateral as measured by the market value of the derivative financial instrument. We manage our risk to financial counterparties through internal credit analysis, limits, and monitoring. Additionally, derivatives and repurchase agreements are entered into with approved counterparties using industry standard agreements. We execute certain OTC derivatives, such as interest rate caps and floors, using bilateral agreements with financial counterparties. Bilateral agreements generally require both parties to post collateral in the event the fair values of the derivative financial instruments meet posting thresholds established under the agreements. If either party defaults on the obligation, the secured party may seize the collateral. Payments related to the exchange of collateral for OTC derivatives are recognized as collateral. We also execute certain derivatives, such as interest rate swaps, with clearinghouses, which require us to post and receive collateral. For these clearinghouse derivatives, these payments are recognized as settlements rather than collateral. Certain derivative instruments contain provisions that require us to either post additional collateral or immediately settle any outstanding liability balances upon the occurrence of a specified credit-risk-related event. No such specified credit-risk-related events occurred during the three months ended March 31, 2023, or 2022. We placed cash and noncash collateral totaling $5 million and $674 million, respectively, supporting our derivative positions at March 31, 2023, compared to $2 million and $384 million of cash and noncash collateral at December 31, 2022, in accounts maintained by counterparties. These amounts include noncash collateral placed at clearinghouses and exclude cash and noncash collateral pledged under repurchase agreements. The receivables for cash collateral placed are included on our Condensed Consolidated Balance Sheet in other assets. We granted our counterparties the right to sell or pledge the noncash collateral. We received cash collateral from counterparties totaling $51 million and $23 million in accounts maintained by counterparties at March 31, 2023, and December 31, 2022, respectively. These amounts exclude cash and noncash collateral pledged under repurchase agreements. The payables for cash collateral received are included on our Condensed Consolidated Balance Sheet in accrued expenses and other liabilities. Balance Sheet Presentation The following table summarizes the amounts of derivative instruments reported on our Condensed Consolidated Balance Sheet. The amounts are presented on a gross basis, are segregated by derivatives that are designated and qualifying as hedging instruments or those that are not, and are further segregated by type of contract within those two categories. Derivative contracts in a receivable and payable position exclude open trade equity on derivatives cleared through central clearing counterparties. Any associated margin exchanged with our central clearing counterparties are treated as settlements of the derivative exposure, rather than collateral. Such payments are recognized as settlements of the derivatives contracts in a receivable and payable position on our Condensed Consolidated Balance Sheet. Notional amounts are reference amounts from which contractual obligations are derived and are not recorded on the balance sheet. In our view, derivative notional is not an accurate measure of our derivative exposure when viewed in isolation from other factors, such as market rate fluctuations and counterparty credit risk.

This represents a subset of the amounts reported in the total hedging adjustment. (b) These amounts include the amortized cost basis and unallocated basis adjustments of closed portfolios of available-for-sale securities used to designate hedging relationships in which the hedged item is the stated amount of assets in the closed portfolios anticipated to be outstanding for the designated hedge period. At both March 31, 2023, and December 31, 2022, the amortized cost basis and unallocated basis adjustments of the closed portfolios used in these hedging relationships was $10.0 billion, of which $9.7 billion represents the amortized cost basis and unallocated basis adjustments of closed portfolios designated in an active hedge relationship. At March 31, 2023, and December 31, 2022, the total cumulative basis adjustments associated with these hedging relationships was a $16 million liability and a $135 million liability, respectively, of which the portion related to discontinued hedging relationships was a $132 million liability and a $138 million liability, respectively. At March 31, 2023, and December 31, 2022, the notional amounts of the designated hedged items were $7.7 billion and $4.0 billion, respectively, with cumulative basis adjustments of a $116 million asset and a $3 million asset, respectively, which would be allocated across the entire remaining closed pool upon termination or maturity of the hedge relationship. Refer to Note 6 for a reconciliation of the amortized cost and fair value of available-for-sale securities. (c) These amounts include the carrying value of closed portfolios of loan receivables used to designate hedging relationships in which the hedged item is the stated amount of assets in the closed portfolios anticipated to be outstanding for the designated hedge period. At March 31, 2023, and December 31, 2022, the carrying value of the closed portfolios used in these hedging relationships was $52.8 billion and $46.4 billion, respectively, of which $51.9 billion and $46.1 billion, respectively, represents the carrying value of closed portfolios designated in an active hedge relationship. At March 31, 2023, and December 31, 2022, the total cumulative basis adjustments associated with these hedging relationships was a $402 million liability and a $617 million liability, respectively, of which the portion related to discontinued hedging relationships was a $47 million liability and a $57 million liability, respectively. At March 31, 2023, and December 31, 2022, the notional amounts of the designated hedged items were $30.5 billion and $22.8 billion, respectively, with cumulative basis adjustments of a $355 million liability and a $560 million liability, respectively, which would be allocated across the entire remaining closed pool upon termination or maturity of the hedge relationship.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We recognized total income tax expense from continuing operations of $68 million for the three months ended March 31, 2023, compared to income tax expense of $191 million for the same period in 2022. The decrease in income tax expense for the three months ended March 31, 2023, compared to the same period in 2022, was primarily due to the tax effects of a decrease in pretax earnings. As of each reporting date, we consider existing evidence, both positive and negative, that could impact our view with regard to future realization of deferred tax assets. We continue to believe it is more likely than not that the benefit for certain foreign tax credit carryforwards and state net operating loss carryforwards will not be realized. In recognition of this risk, we continue to provide a partial valuation allowance on the deferred tax assets relating to these carryforwards and it is reasonably possible that the valuation allowance may change in the next 12 months.

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Fair Value Measurements For purposes of this disclosure, fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability (exit price) in the principal or most advantageous market in an orderly transaction between market participants at the measurement date under current market conditions. Fair value is based on the assumptions we believe market participants would use when pricing an asset or liability. Additionally, entities are required to consider all aspects of nonperformance risk, including the entity’s own credit standing, when measuring the fair value of a liability. U.S. GAAP specifies a three-level hierarchy that is used when measuring and disclosing fair value. The fair value hierarchy gives the highest priority to quoted prices available in active markets (i.e., observable inputs) and the lowest priority to data lacking transparency (i.e., unobservable inputs). An instrument’s categorization within the fair value hierarchy is based on the lowest level of significant input to its valuation. The following is a description of the three hierarchy levels. Level 1 Inputs are quoted prices in active markets for identical assets or liabilities at the measurement date. Additionally, the entity must have the ability to access the active market, and the quoted prices cannot be adjusted by the entity. Level 2 Inputs are other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices in active markets for similar assets or liabilities; quoted prices in inactive markets for identical or similar assets or liabilities; or inputs that are observable or can be corroborated by observable market data by correlation or other means for substantially the full term of the assets or liabilities. Level 3 Unobservable inputs are supported by little or no market activity. The unobservable inputs represent management’s best assumptions of how market participants would price the assets or liabilities. Generally, Level 3 assets and liabilities are valued using pricing models, discounted cash flow methodologies, or similar techniques that require significant judgment or estimation. Judgment is used in estimating inputs to our internal valuation models used to estimate our Level 3 fair value measurements. Level 3 inputs such as interest rate movements, prepayment speeds, credit losses, and discount rates are inherently difficult to estimate. Changes to these inputs can have a significant effect on fair value measurements and amounts that could be realized. The following are descriptions of the valuation methodologies used to measure material assets and liabilities at fair value and details of the valuation models, key inputs to those models, and significant assumptions utilized. • Equity securities — We hold various marketable equity securities measured at fair value with changes in fair value recognized in net income. Measurements based on observable market prices are classified as Level 1. • Available-for-sale securities — We carry our available-for-sale securities at fair value based on external pricing sources. We classify our securities as Level 1 when fair value is determined using quoted prices available for the same instruments trading in active markets. We classify our securities as Level 2 when fair value is determined using prices for similar instruments trading in active markets. We perform pricing validation procedures for our available-for-sale securities. • Derivative instruments — We enter into a variety of derivative financial instruments as part of our risk-management strategies. Certain of these derivatives are exchange traded, such as equity options. To determine the fair value of these instruments, we utilize the quoted market prices for those particular derivative contracts; therefore, we classified these contracts as Level 1. We also execute OTC and centrally cleared derivative contracts, such as interest rate swaps, foreign-currency denominated forward contracts, caps, floors, and agency to-be-announced securities. We utilize third-party-developed valuation models that are widely accepted in the market to value these derivative contracts. The specific terms of the contract and market observable inputs (such as interest rate forward curves, interpolated volatility assumptions, or equity pricing) are used in the model. We classified these derivative contracts as Level 2 because all significant inputs into these models were market observable. We also enter into interest rate lock commitments and forward commitments that are executed as part of our mortgage business, certain of which meet the accounting definition of a derivative and therefore are recorded as derivatives on our Condensed Consolidated Balance Sheet. Interest rate lock commitments are valued using internal pricing models with unobservable inputs, so they are classified as Level 3. We purchase automotive finance receivables and loans from third parties as part of forward flow arrangements and, from time-to-time, execute opportunistic ad-hoc bulk purchases. As part of those agreements, we may withhold a portion of the purchase price from the counterparty and be required to pay the counterparty all or part of the amount withheld at agreed upon measurement dates and determinable amounts if actual credit performance of the acquired loans on the measurement date is better than or equal to what was estimated at the time of acquisition. Because these contracts meet the accounting definition of a derivative, we recognize a liability at fair value for these deferred purchase price payments. The fair value of these liabilities is determined using a discounted cash flow method. To estimate cash flows, we utilize various significant assumptions, including market observable inputs (for example, forward interest rates) and internally developed inputs (for example, prepayment speeds, delinquency levels, and expected credit losses). These liabilities are valued using internal loss models with unobservable inputs, and are classified as Level 3. We are required to consider all aspects of nonperformance risk, including our own credit standing, when measuring fair value of derivative assets and liabilities. We reduce credit risk on the majority of our derivatives by entering into legally enforceable agreements that enable the posting and receiving of collateral associated with the fair value of our derivative positions on an ongoing basis. In the event that we do not enter into legally enforceable agreements that enable the posting and receiving of collateral, we will consider our credit risk in the valuation of derivative liabilities through a DVA and the credit risk of our counterparties in the valuation of derivative assets through a CVA, if warranted. When measuring these valuation adjustments, we generally use credit default swap spreads. Recurring Fair Value The following tables display the assets and liabilities measured at fair value on a recurring basis including financial instruments elected for the fair value option. We often economically hedge the fair value change of our assets or liabilities with derivatives. The tables below display the hedges separately from the hedged items; therefore, they do not directly display the impact of our risk-management activities.

This transfer is deemed to have occurred at the end of the reporting period. Nonrecurring Fair Value We may be required to measure certain assets and liabilities at fair value from time to time. These periodic fair value measures typically result from the application of lower-of-cost or fair value accounting or certain impairment measures. These items would constitute nonrecurring fair value measures. The following tables display assets and liabilities measured at fair value on a nonrecurring basis and still held at March 31, 2023, and December 31, 2022, respectively. The amounts are generally as of the end of each period presented, which approximate the fair value measurements that occurred during each period.

(b) Represents collateral-dependent loans held for investment for which a nonrecurring measurement was made. The related allowance for loan losses represents the cumulative fair value adjustments for those specific receivables.

Accordingly, the table above excludes total gains and losses included in earnings for these items. The carrying values are inclusive of the respective valuation reserve, loan loss allowance, or cumulative adjustment. (b) Represents collateral-dependent loans held for investment for which a nonrecurring measurement was made. The related allowance for loan losses represents the cumulative fair value adjustments for those specific receivables. (c) The allowance provided for repossessed and foreclosed assets represents any cumulative valuation adjustment recognized to adjust the assets to fair value. Fair Value Option for Financial Assets We elected the fair value option for an insignificant amount of conforming mortgage loans held-for-sale and certain personal lending finance receivables. We elected the fair value option for conforming mortgage loans held-for-sale to mitigate earnings volatility by better matching the accounting for the assets with the related derivatives. We elected the fair value option for certain personal lending finance receivables to mitigate the complexities of recording these loans at amortized cost. Our intent in electing fair value measurement was to mitigate a divergence between accounting gains or losses and economic exposure for certain assets and liabilities. Fair Value of Financial Instruments The following table presents the carrying and estimated fair value of financial instruments, except for those recorded at fair value on a recurring basis presented in the previous section of this note titled Recurring Fair Value. When possible, we use quoted market prices to determine fair value. Where quoted market prices are not available, the fair value is internally derived based on appropriate valuation methodologies with respect to the amount and timing of future cash flows and estimated discount rates. However, considerable judgment is required in interpreting current market data to develop the market assumptions and inputs necessary to estimate fair value. As such, the actual amount received to sell an asset or the amount paid to settle a liability could differ from our estimates. Fair value information presented herein was based on information available at March 31, 2023, and December 31, 2022. Estimated fair value ($ in millions) Carrying value Level 1 Level 2 Level 3 Total March 31, 2023 Financial assets Held-to-maturity securities $ 1,047 $ — $ 891 $ — $ 891 Loans held-for-sale, net 500 — — 500 500 Finance receivables and loans, net 132,551 — — 134,325 134,325 FHLB/FRB stock (a) 720 — 720 — 720 Financial liabilities Deposit liabilities $ 52,311 $ — $ — $ 52,251 $ 52,251 Short-term borrowings 1,455 — — 1,487 1,487 Long-term debt 20,480 — 14,044 6,890 20,934 December 31, 2022 Financial assets Held-to-maturity securities $ 1,062 $ — $ 884 $ — $ 884 Loans held-for-sale, net 641 — — 641 641 Finance receivables and loans, net 132,034 — — 133,856 133,856 FHLB/FRB stock (a) 719 — 719 — 719 Financial liabilities Deposit liabilities $ 42,336 $ — $ — $ 41,909 $ 41,909 Short-term borrowings 2,399 — — 2,417 2,417 Long-term debt 17,762 — 12,989 5,263 18,252 (a) Included in other assets on our Condensed Consolidated Balance Sheet. In addition to the financial instruments presented in the above table, we have various financial instruments for which the carrying value approximates the fair value due to their short-term nature and limited credit risk. These instruments include cash and cash equivalents, restricted cash, cash collateral, accrued interest receivable, accrued interest payable, trade receivables and payables, and other short-term receivables and payables. Included in cash and cash equivalents are highly liquid investments that are readily convertible to known amounts of cash and which are subject to an insignificant risk of change in value due to interest rate, quoted price, or penalty on withdrawal. Classified as Level 1 under the fair value hierarchy, cash and cash equivalents generally expose us to limited credit risk and are so near maturity that they present insignificant risk of changes in value because of changes in interest rates.

Offsetting [Abstract]
Offsetting Assets and Liabilities	Offsetting Assets and LiabilitiesOur derivative contracts and repurchase/reverse repurchase transactions are supported by qualifying master netting and master repurchase agreements. These agreements are legally enforceable bilateral agreements that (i) create a single legal obligation for all individual transactions covered by the agreement to the nondefaulting entity upon an event of default of the counterparty, including bankruptcy, insolvency, or similar proceeding, and (ii) provide the nondefaulting entity the right to accelerate, terminate, and close-out on a net basis all transactions under the agreement and to liquidate or set off collateral promptly upon an event of default of the counterparty. To further mitigate the risk of counterparty default related to derivative instruments, we maintain collateral agreements with certain counterparties. The agreements require both parties to maintain collateral in the event the fair values of the derivative financial instruments meet established thresholds. In the event that either party defaults on the obligation, the secured party may seize the collateral. Generally, our collateral arrangements are bilateral such that we and the counterparty post collateral for the obligation. Contractual terms provide for standard and customary exchange of collateral based on changes in the market value of the outstanding derivatives. A party posts additional collateral when their obligation rises or removes collateral when it falls, such that the net replacement cost of the nondefaulting party is covered in the event of counterparty default. In certain instances, as it relates to our derivative instruments, we have the option to report derivative assets and liabilities as well as assets and liabilities associated with cash collateral received or delivered that is governed by a master netting agreement on a net basis as long as certain qualifying criteria are met. Similarly, for our repurchase/reverse repurchase transactions, we have the option to report recognized assets and liabilities subject to a master netting agreement on a net basis if certain qualifying criteria are met. At March 31, 2023, these instruments are reported as gross assets and gross liabilities on the Condensed Consolidated Balance Sheet. For additional information on derivative instruments and hedging activities, refer to Note 18. The composition of offsetting derivative instruments, financial assets, and financial liabilities was as follows.

We do not record noncash collateral received on our Condensed Consolidated Balance Sheet unless certain conditions are met.

Segment Information

Segment Reporting [Abstract]
Segment Information	Segment Information Operating segments are defined as components of an enterprise that engage in business activity from which revenues are earned and expenses incurred for which discrete financial information is available that is evaluated regularly by our chief operating decision maker in deciding how to allocate resources and in assessing performance. We report our results of operations on a business-line basis through four operating segments: Automotive Finance operations, Insurance operations, Mortgage Finance operations, and Corporate Finance operations, with the remaining activity reported in Corporate and Other. The operating segments are determined based on the products and services offered, and reflect the manner in which financial information is currently evaluated by management. The following is a description of each of our reportable operating segments. Dealer Financial Services Dealer Financial Services comprises the following two segments. • Automotive Finance operations — One of the largest full-service automotive finance operations in the United States providing automotive financing services to consumers, automotive dealers and retailers, companies, and municipalities. Our automotive finance services include providing retail installment sales contracts, loans and operating leases, offering term loans to dealers, financing dealer floorplans and other lines of credit to dealers, warehouse lines to automotive retailers, fleet financing, providing financing to companies and municipalities for the purchase or lease of vehicles, and vehicle-remarketing services. • Insurance operations — A complementary automotive-focused business offering both consumer finance protection and insurance products sold primarily through the automotive dealer channel, and commercial insurance products sold directly to dealers. As part of our focus on offering dealers a broad range of consumer financial and insurance products, we provide VSCs, VMCs, and GAP products. We also underwrite select commercial insurance coverages, which primarily insure dealers’ vehicle inventory. Mortgage Finance operations Our held-for-investment portfolio includes our direct-to-consumer Ally Home mortgage offering and bulk purchases of high-quality jumbo and LMI mortgage loans originated by third parties. Through our direct-to-consumer channel, we offer a variety of competitively priced jumbo and conforming fixed- and adjustable-rate mortgage products through a third party. Through the bulk loan channel, we purchase loans from several qualified sellers on a servicing-released basis, allowing us to directly oversee servicing activities and manage refinancing through our direct-to-consumer channel. Corporate Finance operations Our Corporate Finance operations provide senior secured leveraged asset-based and cash flow loans to mostly U.S.-based middle-market companies, with a focus on businesses owned by private equity sponsors. These loans are typically used for leveraged buyouts, refinancing and recapitalizations, mergers and acquisitions, growth, turnarounds, and debtor-in-possession financings. We also provide, through our Lender Finance business, nonbank wholesale-funded managers with partial funding for their direct-lending activities, which is principally leveraged loans. Additionally, we offer a commercial real estate product to serve companies, primarily in the healthcare industry. Corporate and Other Corporate and Other primarily consists of centralized corporate treasury activities, such as management of the cash and corporate investment securities and loan portfolios, short- and long-term debt, retail and brokered deposit liabilities, derivative instruments, original issue discount, and the residual impacts of our corporate FTP and treasury ALM activities. Corporate and Other also includes certain equity investments, which primarily consist of FHLB and FRB stock—as well as other equity investments through Ally Ventures, our strategic investment business—and the management of our legacy mortgage portfolio, which primarily consists of loans originated prior to January 1, 2009, and reclassifications and eliminations between the reportable operating segments. Financial results related to Ally Invest, our digital brokerage and wealth management offering, Ally Lending, our point-of-sale financing business, Ally Credit Card, and CRA loans and related investments are also included within Corporate and Other. We utilize an FTP methodology for the majority of our business operations. The FTP methodology assigns charge rates and credit rates to classes of assets and liabilities on a match funded basis, aligned with the expected duration and the benchmark rate curve plus an assumed credit spread. Match funding allocates interest income and interest expense to these reportable segments so their respective results are insulated from interest rate risk. This methodology is consistent with our ALM practices, which includes managing interest rate risk centrally at a corporate level. The net residual impact of the FTP methodology is included within the results of Corporate and Other. The information presented in our reportable operating segments is based in part on internal allocations and methodologies, including a COH methodology, which involves management judgment. COH methodology is used for measuring the profit and loss of our reportable operating segments. We have various enterprise functions, such as technology, marketing, finance, compliance, internal audit, and risk. Operating expenses from the enterprise functions are either directly allocated to the reportable operating segment, indirectly allocated to the reportable operating segment utilizing the COH methodology, or remain in Corporate and Other. COH methodology considers the reportable operating segment expense base and enterprise function expenses. The reportable operating segment expense base is used to determine the allocation mix. This mix is applied to the allocable expenses in Corporate and Other to determine the COH for the respective reportable operating segment. Allocable enterprise function costs are primarily technology and marketing expenses. Generally, costs that remain within Corporate and Other that are not allocated to our reportable operating segments include marketing sponsorships, treasury and other corporate activities, and charitable contributions. Financial information for our reportable operating segments is summarized as follows.

Contingencies and Other Risks

Contingencies and Other Risks	3 Months Ended

Loss Contingency [Abstract]
Contingencies and Other Risks	Contingencies and Other Risks As a financial-services company, we are regularly involved in pending or threatened legal proceedings and other matters and are or may be subject to potential liability in connection with them. These legal matters may be formal or informal and include litigation and arbitration with one or more identified claimants, certified or purported class actions with yet-to-be-identified claimants, and regulatory or other governmental information-gathering requests, examinations, investigations, and enforcement proceedings. Our legal matters exist in varying stages of adjudication, arbitration, negotiation, or investigation and span our business lines and operations. Claims may be based in law or equity—such as those arising under contracts or in tort and those involving banking, consumer-protection, securities, tax, employment, and other laws—and some can present novel legal theories and allege substantial or indeterminate damages. Ally and its subsidiaries, including Ally Bank, also are or may be subject to potential liability under other contingent exposures, including indemnification, tax, self-insurance, and other miscellaneous contingencies. We accrue for a legal matter or other contingent exposure when a loss becomes probable and the amount of loss can be reasonably estimated. Accruals are evaluated each quarter and may be adjusted, upward or downward, based on our best judgment after consultation with counsel. No assurance exists that our accruals will not need to be adjusted in the future. When a probable or reasonably possible loss on a legal matter or other contingent exposure could be material to our consolidated financial condition, results of operations, or cash flows, we provide disclosure in this note as prescribed by ASC Topic 450, Contingencies . Refer to Note 1 to the Consolidated Financial Statements in our 2022 Annual Report on Form 10-K for additional information related to our policy for establishing accruals. The course and outcome of legal matters are inherently unpredictable. This is especially so when a matter is still in its early stages, the damages sought are indeterminate or unsupported, significant facts are unclear or disputed, novel questions of law or other meaningful legal uncertainties exist, a request to certify a proceeding as a class action is outstanding or granted, multiple parties are named, or regulatory or other governmental entities are involved. Other contingent exposures and their ultimate resolution are similarly unpredictable for reasons that can vary based on the circumstances. As a result, we often are unable to determine how or when threatened or pending legal matters and other contingent exposures will be resolved and what losses may be incrementally and ultimately incurred. Actual losses may be higher or lower than any amounts accrued or estimated for those matters and other exposures, possibly to a significant degree.

Description of Business, Basis of Presentation, and Changes in Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2023
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Our accounting and reporting policies conform to U.S. GAAP. Additionally, where applicable, the policies conform to the accounting and reporting guidelines prescribed by bank regulatory authorities. Certain reclassifications may have been made to the prior periods’ financial statements and notes to conform to the current period’s presentation, which did not have a material impact on our Condensed Consolidated Financial Statements. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and that affect income and expenses during the reporting period and related disclosures. In developing the estimates and assumptions, management uses all available evidence; however, actual results could differ because of uncertainties associated with estimating the amounts, timing, and likelihood of possible outcomes. Our most significant estimates pertain to the allowance for loan losses, valuations of automotive lease assets and residuals, fair value of financial instruments, and the determination of the provision for income taxes.
Finance Receivables and Loans	Finance Receivables and Loans On January 1, 2023, we implemented ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . This guidance eliminates the concept of TDRs and adds new disclosure requirements related to loan modifications to borrowers experiencing financial difficulty and gross charge-offs. We implemented the ASU on a prospective basis, which results in certain aspects of our accounting policies changing for the current year. For significant accounting policy information related to the accounting and reporting of TDRs, for which comparative period information is presented, refer to Note 1 to the Consolidated Financial Statements in our 2022 Annual Report on Form 10-K. Modifications of Loans with Borrowers Experiencing Financial Difficulty We may provide a modification to a borrower who is experiencing financial difficulty if we believe they have the ability and are willing to repay their loan. The type of modification granted will vary depending on our credit risk management practices, as well as the borrower’s financial condition and the characteristics of the loan, including the unpaid balance, the underlying collateral, and the number or types of previous modifications granted. Modifications that we make subject to these requirements include payment extensions, principal forgiveness, and/or interest rate concessions. These modifications generally reduce the borrower’s periodic payment amount. The following is a description of each of these types of modifications. • Payment extensions — Payment extensions include both payment deferrals and contractual maturity extensions. Deferral arrangements allow borrowers to delay a scheduled loan payment to a later date. Deferred loan payments do not affect the original contractual terms of the loan and the contractual maturity date of the loan remains unchanged. Deferrals also include certain forbearance agreements. Within the commercial loan portfolio, deferrals primarily reflect a deferral of interest payments. Under a contractual maturity extension agreement, the last payment date is extended to a future date, contractually lengthening the remaining term of the original loan. • Principal forgiveness — Under principal forgiveness, the outstanding principal balance of a loan is reduced by a specified amount. Principal forgiveness may occur voluntarily as part of a negotiated agreement with a borrower, or involuntarily through a bankruptcy proceeding. Under these involuntary instances, the bankruptcy court in a Chapter 11 or 13 proceeding may order us to reduce the outstanding principal balance of the loan to a specified amount. • Interest rate concessions — Interest rate concessions adjust the contractual interest rate of the loan to a rate that is not consistent with a market rate for a customer with similar credit risk. • Combination — Combination includes loans that have undergone multiple of the above loan modification types. This primarily includes rewritten loans where we grant an interest rate concession and a contractual maturity extension. Significant judgment is required to determine if a borrower is experiencing financial difficulty. These considerations vary by portfolio class. In all cases, the cumulative impacts of all modifications made within the 12-month period before the current modification are considered at the time of the most recent modification. For consumer loans of all classes, various qualitative factors are used for assessing the financial difficulty of the borrower. These factors include, but are not limited to, the borrower’s default status on any of its debts, bankruptcy, and recent changes in financial circumstances (for instance, loss of employment). For commercial loans of all classes, similar qualitative factors are considered when assessing the financial difficulty of the borrower. In addition to the previously noted factors, consideration is also given to the borrower’s forecasted ability to service the debt in accordance with the contractual terms, possible regulatory actions, and other potential business disruptions (for example, the loss of a significant customer or other revenue stream). In our consumer automotive portfolio class of loans, we also provide extensions or deferrals of payments to borrowers whom we deem to be experiencing only temporary financial difficulty. In these cases, there are limits within our operational policies to minimize the number of times a loan can be extended, as well as limits to the length of each extension, including a cumulative cap over the life of the loan. If these limits are breached, the modification may require disclosure as noted in the following paragraph. Before offering an extension or deferral, we evaluate the capacity of the customer to make the scheduled payments after the deferral period. During the deferral period, we continue to accrue interest on the loan as part of the deferral agreement. We grant these extensions or deferrals when we expect to collect all amounts due including interest accrued at the original contract rate. We do not disclose modifications that result in only an insignificant payment delay. In order to assess whether a payment delay is insignificant, we consider the amount of the modified payments subject to delay in conjunction with the unpaid principal balance or the collateral value of the loan, whether or not the delay is significant with respect to the frequency of payments under the original contract, or the loan’s original expected duration. In the cases where payment extensions cumulatively extend beyond 90 days and are more than 10% of the original contractual term, or where the cumulative payment extension within the 12-month period immediately preceding the current modification is beyond 180 days, we deem the delay in payment to be more than insignificant. The financial impacts of modifications that meet the definition of a modification to borrowers experiencing financial difficulty are reported in the period in which they are identified. Additionally, if such a loan defaults within 12 months of the modification, we are required to disclose the instances of redefault. For the purpose of this disclosure, we have determined that a loan is considered to have redefaulted when the loan meets the requirements for evaluation under our charge-off policy, except for commercial loans where redefault is defined as 90 days past due. Nonaccrual Loans Generally, we recognize loans of all classes as past due when they are 30 days delinquent on making a contractually required payment, and loans are placed on nonaccrual status when principal or interest has been delinquent for at least 90 days, or when full collection is not expected. Interest income recognition is suspended when finance receivables and loans are placed on nonaccrual status. Additionally, amortization of premiums and discounts and deferred fees and costs ceases when finance receivables and loans are placed on nonaccrual status. Exceptions include commercial real estate loans that are placed on nonaccrual status when delinquent for 60 days or when full collection is not probable, if sooner. Additionally, a loan can be returned to accrual status when the loan has been brought fully current, the collection of contractual principal and interest is reasonably assured, and six consecutive months of repayment performance is achieved. In certain cases, if a borrower has been current up to the time of the modification and repayment of the debt subsequent to the modification is reasonably assured, we may choose to continue to accrue interest on the loan.
Income Taxes	Income Taxes In calculating the provision for interim income taxes, in accordance with ASC 740, Income Taxes , we apply an estimated annual effective tax rate to year-to-date ordinary income. At the end of each interim period, we estimate the effective tax rate expected to be applicable for the full fiscal year. This method differs from that described in Note 1 to the Consolidated Financial Statements in our 2022 Annual Report on Form 10-K, which describes our annual significant income tax accounting policy and related methodology.
Recently Adopted and Issued Accounting Standards	Recently Adopted Accounting Standards Troubled Debt Restructurings and Vintage Disclosures (ASU 2022-02) In March 2022, the FASB issued ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . The purpose of this guidance is twofold. First, the guidance eliminates TDR recognition and measurement guidance that has been deemed no longer necessary under CECL. The guidance also adds a requirement to incorporate current year gross charge-offs by origination year into the vintage tables. With respect to the TDR impacts, under CECL, credit losses for financial assets measured at amortized cost are determined based on the total current expected credit losses over the life of the financial asset or group of financial assets. Therefore, credit losses on financial assets that have been modified as TDRs would have largely been incorporated in the allowance upon initial recognition. Under ASU 2022-02, we will evaluate whether loan modifications previously characterized as TDRs represent a new loan or a continuation of an existing loan in accordance with ASC Topic 310, Receivables . The guidance also added new disclosures that require an entity to provide information related to loan modifications that are made to borrowers that are deemed to be in financial difficulty. We adopted the ASU on January 1, 2023, on a prospective basis. The impact of these amendments was not material. Recently Issued Accounting Standards Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (ASU 2022-03) In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions . The purpose of this guidance is to clarify that a contractual restriction on the ability to sell an equity security is not considered part of the unit of account of the equity security, and therefore should not be considered when measuring the equity security’s fair value. Additionally, an entity cannot separately recognize and measure a contractual-sale restriction. This guidance also adds specific disclosures related to equity securities that are subject to contractual-sale restrictions, including (1) the fair value of equity securities subject to contractual sale restrictions reflected in the balance sheet, (2) the nature and remaining duration of the restrictions, and (3) the circumstances that could cause a lapse in the restrictions. The amendments are effective on January 1, 2024, with early adoption permitted. The amendments must be applied using a prospective approach with any adjustments from the adoption of the amendments recognized in earnings and disclosed upon adoption. Management does not expect the impact of these amendments to be material. Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (ASU 2023-02) In March 2023, the FASB issued ASU 2023-02, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method . The purpose of this guidance is to expand the use of the proportional amortization method to certain tax equity investments made primarily for the purpose of receiving income tax credits and other income tax benefits. In order to qualify for the proportional amortization method, the following five conditions must be met: (1) it is probable that the income tax credits allocable to the tax equity investor will be available, (2) the tax equity investor does not have the ability to exercise significant influence over the operating and financial policies of the underlying project, (3) substantially all of the projected benefits are from income tax credits and other income tax benefits, (4) the tax equity investor’s projected yield is based solely on the cash flows from the income tax credits and other income tax benefits is positive, and (5) the tax equity investor is a limited liability investor in the limited liability entity for both legal and tax purposes, and the tax equity investor’s liability is limited to its capital investment. Selecting the proportional amortization method will be an accounting policy election that must be applied on a tax-credit-program-by-tax-credit-program basis rather than at the entity level or to individual investments. Additionally, in order to apply the proportional amortization method to qualifying investments, an entity must use the flow-through method when accounting for the receipt of the investment tax credits. This guidance also adds disclosure requirements related to tax credit programs where the proportional amortization method has been elected. The amendments are effective on January 1, 2024, with early adoption permitted. The amendments must be applied using either a modified retrospective or retrospective approach with any adjustments from the adoption of the amendments recognized in retained earnings and disclosed upon adoption. In the event that we elect to apply the proportional amortization method to any qualifying programs upon adoption, management is still assessing the total impacts of these amendments, but does not expect the impact of these amendments to be material.
Fair Value Measurements	The following are descriptions of the valuation methodologies used to measure material assets and liabilities at fair value and details of the valuation models, key inputs to those models, and significant assumptions utilized. • Equity securities — We hold various marketable equity securities measured at fair value with changes in fair value recognized in net income. Measurements based on observable market prices are classified as Level 1. • Available-for-sale securities — We carry our available-for-sale securities at fair value based on external pricing sources. We classify our securities as Level 1 when fair value is determined using quoted prices available for the same instruments trading in active markets. We classify our securities as Level 2 when fair value is determined using prices for similar instruments trading in active markets. We perform pricing validation procedures for our available-for-sale securities. • Derivative instruments — We enter into a variety of derivative financial instruments as part of our risk-management strategies. Certain of these derivatives are exchange traded, such as equity options. To determine the fair value of these instruments, we utilize the quoted market prices for those particular derivative contracts; therefore, we classified these contracts as Level 1. We also execute OTC and centrally cleared derivative contracts, such as interest rate swaps, foreign-currency denominated forward contracts, caps, floors, and agency to-be-announced securities. We utilize third-party-developed valuation models that are widely accepted in the market to value these derivative contracts. The specific terms of the contract and market observable inputs (such as interest rate forward curves, interpolated volatility assumptions, or equity pricing) are used in the model. We classified these derivative contracts as Level 2 because all significant inputs into these models were market observable. We also enter into interest rate lock commitments and forward commitments that are executed as part of our mortgage business, certain of which meet the accounting definition of a derivative and therefore are recorded as derivatives on our Condensed Consolidated Balance Sheet. Interest rate lock commitments are valued using internal pricing models with unobservable inputs, so they are classified as Level 3. We purchase automotive finance receivables and loans from third parties as part of forward flow arrangements and, from time-to-time, execute opportunistic ad-hoc bulk purchases. As part of those agreements, we may withhold a portion of the purchase price from the counterparty and be required to pay the counterparty all or part of the amount withheld at agreed upon measurement dates and determinable amounts if actual credit performance of the acquired loans on the measurement date is better than or equal to what was estimated at the time of acquisition. Because these contracts meet the accounting definition of a derivative, we recognize a liability at fair value for these deferred purchase price payments. The fair value of these liabilities is determined using a discounted cash flow method. To estimate cash flows, we utilize various significant assumptions, including market observable inputs (for example, forward interest rates) and internally developed inputs (for example, prepayment speeds, delinquency levels, and expected credit losses). These liabilities are valued using internal loss models with unobservable inputs, and are classified as Level 3. We are required to consider all aspects of nonperformance risk, including our own credit standing, when measuring fair value of derivative assets and liabilities. We reduce credit risk on the majority of our derivatives by entering into legally enforceable agreements that enable the posting and receiving of collateral associated with the fair value of our derivative positions on an ongoing basis. In the event that we do not enter into legally enforceable agreements that enable the posting and receiving of collateral, we will consider our credit risk in the valuation of derivative liabilities through a DVA and the credit risk of our counterparties in the valuation of derivative assets through a CVA, if warranted. When measuring these valuation adjustments, we generally use credit default swap spreads.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Schedule of Derivative Instruments in Statement of Financial Position	The following table summarizes the amounts of derivative instruments reported on our Condensed Consolidated Balance Sheet. The amounts are presented on a gross basis, are segregated by derivatives that are designated and qualifying as hedging instruments or those that are not, and are further segregated by type of contract within those two categories. Derivative contracts in a receivable and payable position exclude open trade equity on derivatives cleared through central clearing counterparties. Any associated margin exchanged with our central clearing counterparties are treated as settlements of the derivative exposure, rather than collateral. Such payments are recognized as settlements of the derivatives contracts in a receivable and payable position on our Condensed Consolidated Balance Sheet. Notional amounts are reference amounts from which contractual obligations are derived and are not recorded on the balance sheet. In our view, derivative notional is not an accurate measure of our derivative exposure when viewed in isolation from other factors, such as market rate fluctuations and counterparty credit risk.

Fair Value, by Balance Sheet Grouping	The following table presents the carrying and estimated fair value of financial instruments, except for those recorded at fair value on a recurring basis presented in the previous section of this note titled Recurring Fair Value. When possible, we use quoted market prices to determine fair value. Where quoted market prices are not available, the fair value is internally derived based on appropriate valuation methodologies with respect to the amount and timing of future cash flows and estimated discount rates. However, considerable judgment is required in interpreting current market data to develop the market assumptions and inputs necessary to estimate fair value. As such, the actual amount received to sell an asset or the amount paid to settle a liability could differ from our estimates. Fair value information presented herein was based on information available at March 31, 2023, and December 31, 2022.
