(AHM or the Parent). Honda Canada Finance Inc. (HCFI) is a majority-owned subsidiary of AHFC. Noncontrolling interest in HCFI is held by Honda Canada Inc. (HCI), an affiliate of AHFC. AHM is a wholly-owned subsidiary and HCI is an indirect wholly-owned subsidiary of Honda Motor Co., Ltd. (HMC). AHM and HCI are the sole authorized distributors of Honda and Acura products, including motor vehicles, parts and accessories in the United States and Canada. Unless otherwise indicated by the context, all references to the “Company”, “we”, “us”, and “our” in this report include AHFC and its consolidated subsidiaries, and references to “AHFC” refer solely to American Honda Finance Corporation (excluding AHFC’s subsidiaries). Basis of Presentation The unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim information, and instructions to the Quarterly Report on Form 10-Q and Rule 10-01 of Regulation S-X. In the opinion of management, these unaudited interim financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results for the interim periods presented. Results for interim periods should not be considered indicative of results for the full year or for any other interim period. These unaudited interim financial statements should be read in conjunction with the Company’s audited consolidated financial statements, significant accounting policies, and the other notes to the consolidated financial statements for the fiscal year ended March 31, 2023 included in the Company’s Annual Report on Form 10-K, which was filed with the Securities and Exchange Commission (SEC) on June 23, 2023. All significant intercompany balances and transactions have been eliminated upon consolidation. Recently Adopted Accounting Standard Effective April 1, 2023, the Company adopted Accounting Standards Update (ASU) 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . The amendments eliminate the accounting guidance for troubled debt restructurings by creditors that have adopted ASU 2016-13 and enhance the disclosure requirements for certain loan refinancings and restructurings when borrowers are experiencing financial difficulty. In addition, the amendments require the disclosure of current-period gross write-offs for financing receivables by year of origination in the vintage disclosures. The adoption of this standard did not have a material impact on the consolidated financial statements. Recently Issued Accounting Standards In November 2023, the Financial Accounting Standards Board (FASB) issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures . The amendments improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments are effective for the Company for fiscal years beginning April 1, 2024 and for interim periods beginning April 1, 2025. The Company is currently assessing the impact of this standard on the consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures . The amendments enhance the transparency and decision usefulness of income tax disclosures, including jurisdictional information, by requiring consistent categories and greater disaggregation of information in the rate reconciliation and income taxes paid disclosures. The amendments also eliminate certain disclosure requirements related to uncertain tax positions and unrecognized deferred tax liabilities. The amendments are effective for the Company for fiscal years beginning April 1, 2025. The Company is currently assessing the impact of this standard on the consolidated financial statements. .

These retail loans are restricted and serve as collateral for the payment of the related secured debt obligations. Refer to Note 9 for additional information. Allowance for Credit Losses The following is a summary of the activity in the allowance for credit losses of finance receivables: Three and nine months ended December 31, 2023 Retail Dealer Total (U.S. dollars in millions) Beginning balance as of October 1, 2023 $ 327 $ 5 $ 332 Provision 72 2 74 Charge-offs (87) — (87) Recoveries 24 — 24 Effect of translation adjustment — — — Ending balance as of December 31, 2023 $ 336 $ 7 $ 343 Beginning balance as of April 1, 2023 $ 248 $ 5 $ 253 Provision 220 2 222 Charge-offs (202) — (202) Recoveries 70 — 70 Effect of translation adjustment — — — Ending balance as of December 31, 2023 $ 336 $ 7 $ 343 Three and nine months ended December 31, 2022 Retail Dealer Total (U.S. dollars in millions) Beginning balance as of October 1, 2022 $ 216 $ 5 $ 221 Provision 49 — 49 Charge-offs (56) — (56) Recoveries 22 — 22 Effect of translation adjustment — — — Ending balance as of December 31, 2022 $ 231 $ 5 $ 236 Beginning balance as of April 1, 2022 $ 206 $ 5 $ 211 Provision 101 — 101 Charge-offs (140) (140) Recoveries 65 — 65 Effect of translation adjustment (1) — (1) Ending balance as of December 31, 2022 $ 231 $ 5 $ 236 The allowance increased during the nine months ended December 31, 2023 primarily due to the expected credit losses recognized on the high volume of retail loan acquisitions during the period. Delinquencies Collection experience provides an indication of the credit quality of finance receivables. For retail loans, delinquencies are a good predictor of charge-offs in the near term. The likelihood of accounts charging off is significantly higher once an account becomes 60 days delinquent. Retail loans are considered delinquent if more than 10% of a scheduled payment is contractually past due on a cumulative basis. Dealer loans are considered delinquent when any payment is contractually past due. The following is an aging analysis of past due finance receivables: 30 – 59 days 60 – 89 days 90 days Total Current or Total (U.S. dollars in millions) December 31, 2023 Retail loans: New auto $ 290 $ 81 $ 22 $ 393 $ 32,650 $ 33,043 Used and certified auto 153 46 13 212 7,664 7,876 Motorcycle and other 17 8 5 30 1,334 1,364 Total retail loans 460 135 40 635 41,648 42,283 Dealer loans: Wholesale flooring 1 — — 1 2,380 2,381 Commercial loans — — — — 1,214 1,214 Total dealer loans 1 — — 1 3,594 3,595 Total finance receivables $ 461 $ 135 $ 40 $ 636 $ 45,242 $ 45,878 March 31, 2023 Retail loans: New auto $ 217 $ 44 $ 11 $ 272 $ 27,479 $ 27,751 Used and certified auto 103 25 6 134 5,870 6,004 Motorcycle and other 14 5 2 21 1,226 1,247 Total retail loans 334 74 19 427 34,575 35,002 Dealer loans: Wholesale flooring — — — — 1,946 1,946 Commercial loans — — — — 890 890 Total dealer loans — — — — 2,836 2,836 Total finance receivables $ 334 $ 74 $ 19 $ 427 $ 37,411 $ 37,838 Credit Quality Indicators Credit losses are an expected cost of extending credit. The majority of our credit risk is with consumer financing and to a lesser extent with dealer financing. Exposure to credit risk in retail loans is managed through regular monitoring and adjusting of underwriting standards, pricing of contracts for expected losses, and focusing collection efforts to minimize losses. Exposure to credit risk for dealers is managed through ongoing reviews of their financial condition and payment performance. Retail Loan Segment The Company utilizes proprietary credit scoring systems to evaluate the credit risk of applicants and assign internal credit grades at origination. Factors used to develop a customer’s credit grade include the terms of the contract, the loan-to-value ratio, the customer’s debt ratios, and credit bureau attributes such as the number of trade lines, utilization ratio, and number of credit inquiries. Different scorecards are utilized depending on the type of product financed. The Company regularly reviews and analyzes the performance of the consumer-financing portfolio to ensure the effectiveness of underwriting guidelines, purchasing criteria and scorecard predictability of customers. Internal credit grades are determined only at the time of origination and are not reassessed during the life of the contract. The following describes the internal credit grade ratings. A - Borrowers classified as very low credit risks. Based on their application and credit bureau report, they have the ability to pay and have shown a willingness to pay. Generally, A credit borrowers have an extensive credit history, an excellent payment record and extensive financial resources. B - Borrowers classified as relatively low credit risks. Based on their application and credit bureau report, they have the ability to pay and have shown a willingness to pay. Generally, B credit borrowers may have one or more conditions that could reduce the internal credit score, such as a shorter credit history or a minor credit weakness. C - Borrowers classified as moderate credit risks. Based on their application and credit bureau report, they may have limited financial resources, limited credit history, or a weakness in credit history. D - Borrowers classified as relatively higher credit risks. Based on their application and credit bureau report, they may have very limited financial resources, very limited or no credit history, or a poor credit history. Others - Borrowers, including businesses, without credit bureau reports.

Dealerships are assigned an internal risk rating based on an assessment of their financial condition and other factors. Factors including liquidity, financial strength, management effectiveness, and operating efficiency are evaluated when assessing their financial condition. Financing limits and interest rates are based upon these risk ratings. Monitoring activities including financial reviews and inventory inspections are performed more frequently for dealerships with weaker risk ratings. The financial conditions of dealerships are reviewed and their risk ratings are updated at least annually. Dealerships have been divided into the following groups: Group I - Dealerships in the strongest internal risk rating tier Group II - Dealerships with internal risk ratings below the strongest tier Group III - Dealerships with impaired loans The following table summarizes the amortized cost of dealer loans by risk rating groups: Commercial loans by vintage fiscal year 2024 2023 2022 2021 2020 Prior Revolving loans Wholesale Flooring Total (U.S. dollars in millions) December 31, 2023 Group I $ 147 $ 56 $ 15 $ 116 $ 45 $ 85 $ 685 $ 1,505 $ 2,654 Group II 41 3 — — — 21 — 873 938 Group III — — — — — — — 3 3 Total dealer loans $ 188 $ 59 $ 15 $ 116 $ 45 $ 106 $ 685 $ 2,381 $ 3,595 Gross charge-offs for the nine months ended December 31, 2023 $ — $ — $ — $ — $ — $ — $ — $ — $ — Commercial loans by vintage fiscal year 2023 2022 2021 2020 2019 Prior Revolving loans Wholesale Flooring Total (U.S. dollars in millions) March 31, 2023 Group I $ 67 $ 10 $ 143 $ 56 $ 24 $ 89 $ 428 $ 1,223 $ 2,040 Group II 1 6 29 6 — 31 — 723 796 Group III — — — — — — — — — Total dealer loans $ 68 $ 16 $ 172 $ 62 $ 24 $ 120 $ 428 $ 1,946 $ 2,836 Loan Modifications The contractual terms of loans may be modified when borrowers are experiencing financial difficulties in an effort to mitigate losses. There were no dealer loans that were modified for dealers experiencing financial difficulties during the nine months ended December 31, 2023. Payment deferrals are granted on retail loans, however the delays in payments are considered insignificant since the number of deferred payments are limited and interest continues to accrue during the deferral period. Starting in April 2023, the Company began granting term extensions on retail loans in the United States. Term extensions extend the maturity date of the loan which reduces the monthly payments over the remaining extended term of the loan. Term extensions do not change the contractual interest rates or reduce the outstanding principal balances. During the nine months ended December 31, 2023, term extensions were not material to the Company’s consolidated financial statement. Retail loans may also be modified in reorganization proceedings pursuant to the U.S. Bankruptcy Code which may include interest rate adjustments, term extensions, and principal forgiveness. Retail loans modified under bankruptcy protection were not material to the Company’s consolidated financial statements during the nine months ended December 31, 2023.

Income Taxes	Dec. 31, 2023
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes On August 16, 2022, the Inflation Reduction Act of 2022 (IRA) was enacted into law. The IRA includes tax provisions for a new corporate alternative minimum tax (CAMT) of 15% on adjusted financial statement income of corporations with profits greater than $1.0 billion, effective for taxable years beginning after December 31, 2022, in addition to a new tax credit for qualified commercial clean vehicles (QCCV) that applies to vehicles acquired after December 31, 2022. At December 31, 2023, based on proposed guidance and regulations issued to date, the Company does not expect to incur CAMT liability for fiscal year 2024 and expects to generate an immaterial amount of QCCV tax credits during the fourth quarter of fiscal year 2024. The Company will continue to evaluate the effects of IRA as additional guidance and regulations are issued. The Company's effective tax rate was 26.7% and 26.4% for the three months ended December 31, 2023 and 2022, respectively, and 28.3% and 26.4% for the nine months ended December 31, 2023 and 2022, respectively. The increase in effective tax rates for the three and nine months ended December 31, 2023 was primarily due to an increase in state taxes. The Company's effective tax rates for the three and nine months ended December 31, 2023, differ from the U.S. federal statutory tax rate primarily as a result of U.S. state taxes. The Company does not provide for income taxes on its share of the undistributed earnings of HCFI which are intended to be indefinitely reinvested outside the United States. At December 31, 2023, $1.0 billion of accumulated undistributed earnings of HCFI were intended to be so reinvested. If the undistributed earnings as of December 31, 2023 were to be distributed, the tax liability associated with these earnings would be $148 million, inclusive of currency translation adjustments. As of December 31, 2023, the Company is subject to examination for U.S. federal returns filed for the taxable years ended March 31, 2014 through 2022, and for various U.S state returns filed for the taxable years ended March 31, 2008 through 2022. The Company’s Canadian subsidiary, HCFI, is subject to examination for federal and provincial returns filed for the taxable years ended March 31, 2017 through 2023. The Company believes appropriate provision has been made for all outstanding issues for all open years and does not expect any material changes in the amounts of unrecognized tax benefits during the fiscal year ending March 31, 2024.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Operating Leases The Company leases certain premises and equipment through operating leases. AHFC leases its premises and equipment from AHM and third parties, and HCFI leases its premises from HCI. Many of the Company's leases contain renewal options, and generally have no residual value guarantees or material covenants. When it is reasonably certain that the Company will exercise the option to renew a lease, the Company will include the renewal option in the evaluation of the lease term. The Company has elected not to recognize right-of-use assets or lease liabilities for leases with a lease term of less than one year. As most of the Company's leases do not provide an implicit rate, the incremental borrowing rate is used in determining the present value of lease payments. The right-of-use assets in operating lease arrangements are reported in other assets on the Company's consolidated balance sheets. Operating lease liabilities are reported in other liabilities on the Company's consolidated balance sheets. At December 31, 2023, maturities of operating lease liabilities were as follows: Twelve-month periods ending December 31, (U.S. dollars in millions) 2024 $ 10 2025 9 2026 10 2027 10 2028 9 Thereafter 26 Total undiscounted future lease obligations 74 Less: imputed interest (10) Operating lease liabilities $ 64 Lease expense under operating leases was $2 million for both the three months ended December 31, 2023 and 2022, and $7 million for both the nine months ended December 31, 2023 and 2022. Lease expense is included within general and administrative expenses. As of December 31, 2023, the weighted average remaining lease term for operating leases was 7.8 years and the weighted average remaining discount rate for operating leases was 3% . Revolving Lines of Credit to Dealerships The Company extends commercial revolving lines of credit to dealerships to support their business activities including facilities refurbishment and general working capital requirements. The amounts borrowed are generally secured by the assets of the borrowing entity. The unused balance of commercial revolving lines of credit was $425 million as of December 31, 2023. The Company also has commitments to finance the construction of auto dealership facilities. The remaining unfunded balance for these construction loans was $9 million as of December 31, 2023. Legal Proceedings and Regulatory Matters The Company establishes accruals for legal claims when payments associated with the claims become probable and the costs can be reasonably estimated. When able, the Company will determine estimates of reasonably possible loss or range of loss, whether in excess of any related accrued liability or where there is no accrued liability. Given the inherent uncertainty associated with legal matters, the actual costs of resolving legal claims and associated costs of defense may be substantially higher or lower than the amounts for which accruals have been established. The Company is involved, in the ordinary course of business, in various legal proceedings including claims of individual customers and purported class action lawsuits. Certain of these actions are similar to suits filed against other financial institutions and captive finance companies concerning business practices and policies. The Company is also subject to regulation, supervision, and licensing under various federal, state, provincial, and local statutes, ordinances and regulations which involve governmental reviews and inquiries from time to time. Based on available information and established accruals, management does not believe it is reasonably possible that the results of these proceedings, in the aggregate, will have a material adverse effect on the Company’s consolidated financial statements. In November 2023, the Company received a civil investigative demand issued by the Consumer Financial Protection Bureau (CFPB) in connection with the Company’s furnishing of credit reporting information on consumer credit accounts. The Company is cooperating with the CFPB and is responding to their information requests. Management cannot predict the eventual scope, duration or outcome of this investigation and is unable to estimate the amount or range of potential losses, if any, at this time.

Securitizations and Variable Interest Entities (VIE)	Dec. 31, 2023
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Securitizations and Variable Interest Entities (VIE)	Securitizations and Variable Interest Entities (VIE) The Company utilizes SPEs for its asset-backed securitizations and these SPEs are considered VIEs, which are required to be consolidated by their primary beneficiary. The Company is considered to be the primary beneficiary of these SPEs due to (i) the power to direct the activities of the SPEs that most significantly impact the SPEs’ economic performance through the Company's role as servicer, and (ii) the obligation to absorb losses or the right to receive residual returns that could potentially be significant to the SPEs through the subordinated certificates and residual interest retained. The debt securities issued by the SPEs to third-party investors along with the assets of the SPEs are included in the Company’s consolidated financial statements. During the nine months ended December 31, 2023 and 2022, the Company issued notes through asset-backed securitizations, which were accounted for as secured financing transactions totaling $5.4 billion and $1.4 billion, respectively. The notes were secured by assets with an initial balance of $5.8 billion and $1.5 billion, respectively. The table below presents the carrying amounts of assets and liabilities of consolidated SPEs as they are reported in the Company’s consolidated balance sheets. All amounts exclude intercompany balances, which have been eliminated upon consolidation. Investors in notes issued by a SPE only have recourse to the assets of such SPE and do not have recourse to the assets of AHFC, HCFI, or its other subsidiaries or to other SPEs. The assets of SPEs are the only source of funds for repayment on the notes. There were no outstanding operating lease securitizations as of December 31, 2023. December 31, 2023 Assets Liabilities (U.S. dollars in millions) Securitized assets Restricted cash (1) Other Secured debt Other Retail loan securitizations $ 9,189 $ 671 $ 21 $ 8,722 $ 14 March 31, 2023 Assets Liabilities (U.S. dollars in millions) Securitized assets Restricted cash (1) Other Secured debt Other Retail loan securitizations $ 7,216 $ 419 $ 12 $ 6,844 $ 6 Operating lease securitizations 168 1 1 83 1 Total $ 7,384 $ 420 $ 13 $ 6,927 $ 7 ________________________ (1) Included with other assets in the Company’s consolidated balance sheets (Note 10). In their role as servicers, AHFC and HCFI collect payments on the underlying securitized assets on behalf of the SPEs. Cash collected during a calendar month is required to be remitted to the SPEs in the following month. AHFC and HCFI are not restricted from using the cash collected for their general purposes prior to the remittance to the SPEs. As of December 31, 2023 and March 31, 2023, AHFC and HCFI had combined cash collections of $425 million and $400 million, respectively, which were required to be remitted to the SPEs.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. Level 1 inputs are quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 inputs are those other than quoted prices included within Level 1 that are observable for the asset or liability. Level 3 inputs are unobservable inputs for the asset or liability. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). Nonperformance risk is also required to be reflected in the fair value measurement, including an entity’s own credit standing when measuring the fair value of a liability. Recurring Fair Value Measurements The following tables summarize the fair value hierarchy of assets and liabilities measured at fair value on a recurring basis: December 31, 2023 Level 1 Level 2 Level 3 Total (U.S. dollars in millions) Assets: Derivative instruments: Interest rate swaps $ — $ 777 $ — $ 777 Cross currency swaps — 65 — 65 Total assets $ — $ 842 $ — $ 842 Liabilities: Derivative instruments: Interest rate swaps $ — $ 892 $ — $ 892 Cross currency swaps — 501 — 501 Total liabilities $ — $ 1,393 $ — $ 1,393 March 31, 2023 Level 1 Level 2 Level 3 Total (U.S. dollars in millions) Assets: Derivative instruments: Interest rate swaps $ — $ 1,133 $ — $ 1,133 Cross currency swaps — — — — Total assets $ — $ 1,133 $ — $ 1,133 Liabilities: Derivative instruments: Interest rate swaps $ — $ 1,062 $ — $ 1,062 Cross currency swaps — 674 — 674 Total liabilities $ — $ 1,736 $ — $ 1,736 The valuation techniques used in measuring assets and liabilities at fair value on a recurring basis are described below: Derivative Instruments The Company’s derivatives are transacted in over-the-counter markets and quoted market prices are not readily available. The Company uses third-party developed valuation models to value derivative instruments. These models estimate fair values using discounted cash flow modeling techniques, which utilize the contractual terms of the derivative instruments and market-based inputs, including interest rates and foreign exchange rates. Discount rates incorporate counterparty and HMC specific credit default spreads to reflect nonperformance risk. The Company’s derivative instruments are classified as Level 2 since all significant inputs are observable and do not require management judgment. There were no transfers between fair value hierarchy levels during the nine months ended December 31, 2023 and 2022. Refer to Note 5 for additional information on derivative instruments. Nonrecurring Fair Value Measurements The following tables summarize nonrecurring fair value measurements recognized for assets still held at the end of the reporting periods presented: Level 1 Level 2 Level 3 Total Lower-of-cost (U.S. dollars in millions) December 31, 2023 Vehicles held for disposition $ — $ — $ 66 $ 66 $ 22 December 31, 2022 Vehicles held for disposition $ — $ — $ 32 $ 32 $ 8 The following describes the methodologies and assumptions used in nonrecurring fair value measurements, which relate to the application of lower of cost or fair value accounting on long-lived assets. Vehicles Held for Disposition Vehicles held for disposition consist of returned and repossessed vehicles. They are valued at the lower of their carrying value or estimated fair value, less estimated disposition costs. The fair value is based on current average selling prices of like vehicles at wholesale used vehicle auctions. Fair Value of Financial Instruments The following tables summarize the carrying values and fair values of the Company’s financial instruments except for those measured at fair value on a recurring basis. Certain financial instruments and all nonfinancial assets and liabilities are excluded from fair value disclosure requirements including the Company’s investment in operating leases. The carrying values of cash and cash equivalents, restricted cash, and short-term investments approximate fair values due to the short-term nature and limited credit risk of the instruments.

Although the Company is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been updated since those dates, and therefore, the current estimates of fair value at dates subsequent to those dates may differ significantly from the amounts presented herein.

Segment Information	Dec. 31, 2023
Segment Reporting [Abstract]
Segment Information	Segment Information The Company’s reportable segments are based on the two geographic regions where operating results are measured and evaluated by management: the United States and Canada. Segment performance is evaluated using an internal measurement basis, which differs from the Company’s consolidated results prepared in accordance with GAAP. Segment performance is evaluated on a pre-tax basis before the effect of valuation adjustments on derivative instruments and revaluations of foreign currency denominated debt. Since the Company does not elect to apply hedge accounting, the impact to earnings resulting from these valuation adjustments as reported under GAAP is not representative of segment performance as evaluated by management. Realized gains and losses on derivative instruments, net of realized gains and losses on foreign currency denominated debt, are included in the measure of net revenues when evaluating segment performance. No adjustments are made to segment performance to allocate any revenues or expenses. Financing products offered throughout the United States and Canada are substantially similar. Segment revenues from the various financing products are reported on the same basis as GAAP consolidated results. Financial information for the three and nine months ended December 31, 2023 and 2022 is summarized in the following tables: United Canada Valuation Consolidated (U.S. dollars in millions) Three months ended December 31, 2023 Revenues: Retail $ 495 $ 58 $ — $ 553 Dealer 54 6 — 60 Operating leases 1,285 219 — 1,504 Total revenues 1,834 283 — 2,117 Leased vehicle expenses 898 168 — 1,066 Interest expense 404 62 — 466 Realized (gains)/losses on derivatives and foreign (13) (15) 28 — Net revenues 545 68 (28) 585 Other income, net 27 3 — 30 Total net revenues 572 71 (28) 615 Expenses: General and administrative expenses 109 12 — 121 Provision for credit losses 71 3 — 74 Early termination loss on operating leases 29 1 — 30 Gain on derivative instruments — — (308) (308) Loss on foreign currency revaluation of debt — — 235 235 Income before income taxes $ 363 $ 55 $ 45 $ 463 Nine months ended December 31, 2023 Revenues: Retail $ 1,327 $ 160 $ — $ 1,487 Dealer 145 17 — 162 Operating leases 3,881 690 — 4,571 Total revenues 5,353 867 — 6,220 Leased vehicle expenses 2,753 533 — 3,286 Interest expense 1,009 176 — 1,185 Realized (gains)/losses on derivatives and foreign (86) (48) 134 — Net revenues 1,677 206 (134) 1,749 Other income, net 74 11 — 85 Total net revenues 1,751 217 (134) 1,834 Expenses: General and administrative expenses 339 38 — 377 Provision for credit losses 214 8 — 222 Early termination loss on operating leases 69 1 — 70 Gain on derivative instruments — — (132) (132) Loss on foreign currency revaluation of debt — — 77 77 Income before income taxes $ 1,129 $ 170 $ (79) $ 1,220 December 31, 2023 Finance receivables, net $ 40,691 $ 4,844 $ — $ 45,535 Investment in operating leases, net 23,543 3,703 — 27,246 Total assets 67,425 8,892 — 76,317 United Canada Valuation Consolidated (U.S. dollars in millions) Three months ended December 31, 2022 Revenues: Retail $ 321 $ 42 $ — $ 363 Dealer 29 4 — 33 Operating leases 1,335 253 — 1,588 Total revenues 1,685 299 — 1,984 Leased vehicle expenses 979 199 — 1,178 Interest expense 189 45 — 234 Realized (gains)/losses on derivatives and foreign (34) (13) 47 — Net revenues 551 68 (47) 572 Other income, net 23 4 — 27 Total net revenues 574 72 (47) 599 Expenses: General and administrative expenses 98 14 — 112 Provision for credit losses 47 2 — 49 Early termination loss on operating leases 20 — — 20 Loss on derivative instruments — — (404) (404) Gain on foreign currency revaluation of debt — — 401 401 Income before income taxes $ 409 $ 56 $ (44) $ 421 Nine months ended December 31, 2022 Revenues: Retail $ 955 $ 126 $ — $ 1,081 Dealer 66 8 — 74 Operating leases 4,222 821 — 5,043 Total revenues 5,243 955 — 6,198 Leased vehicle expenses 3,100 640 — 3,740 Interest expense 500 114 — 614 Realized (gains)/losses on derivatives and foreign (48) (24) 72 — Net revenues 1,691 225 (72) 1,844 Other income, net 55 10 — 65 Total net revenues 1,746 235 (72) 1,909 Expenses: General and administrative expenses 314 41 — 355 Provision for credit losses 94 7 — 101 Early termination loss on operating leases 32 1 — 33 Loss on derivative instruments — — 722 722 Gain on foreign currency revaluation of debt — — (476) (476) Income before income taxes $ 1,306 $ 186 $ (318) $ 1,174 December 31, 2022 Finance receivables, net $ 31,809 $ 4,008 $ — $ 35,817 Investment in operating leases, net 24,535 4,108 — 28,643 Total assets 60,403 8,565 — 68,968
