Basis of Presentation and Significant Accounting Policies	Mar. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Note 1 – Basis of Presentation and Significant Accounting Policies Nature of Operations Toyota Motor Credit Corporation (“TMCC”) is a wholly-owned subsidiary of Toyota Financial Services International Corporation (“TFSIC”), a California corporation, which is a wholly-owned subsidiary of Toyota Financial Services Corporation (“TFSC”), a Japanese corporation. TFSC, in turn, is a wholly-owned subsidiary of Toyota Motor Corporation (“TMC”), a Japanese corporation. TFSC manages TMC’s worldwide financial services operations. References herein to the “Company”, “we”, “our”, and “us” denote TMCC and its consolidated subsidiaries. TMCC is marketed under the brands of Toyota Financial Services, Lexus Financial Services, and Mazda Financial Services. We provide a variety of finance and voluntary vehicle and payment protection products and services to authorized Toyota and Lexus dealers or dealer groups, private label dealers or dealer groups, and, to a lesser extent, other domestic and import franchise dealers (collectively referred to as “dealers”) and their customers in the United States of America (excluding Hawaii) (the “U.S.”) and Puerto Rico. Our business is substantially dependent upon the sale of Toyota, Lexus, and private label vehicles. Our products and services fall primarily into the following categories: • Finance Operations - We acquire retail installment sales contracts from dealers in the U.S. and Puerto Rico (“retail contracts”) and leasing contracts accounted for as operating leases (“lease contracts”) from dealers in the U.S. We collectively refer to our retail and lease contracts as the “consumer portfolio.” We also provide dealer financing, including wholesale financing, working capital loans, revolving lines of credit and real estate financing to dealers in the U.S. and Puerto Rico. We collectively refer to our dealer financing portfolio as the “dealer portfolio.” • Voluntary Protection Operations - Through Toyota Motor Insurance Services, Inc., a wholly-owned subsidiary, and its insurance company subsidiaries (collectively referred to as “TMIS”), we provide marketing, underwriting, and claims administration for voluntary vehicle and payment protection products sold by dealers in the U.S. Our voluntary vehicle and payment protection products include vehicle service, guaranteed auto protection, prepaid maintenance, excess wear and use, tire and wheel protection, key replacement protection, and used vehicle limited warranty contracts (“voluntary protection products”). TMIS also provides coverage and related administrative services to certain of our affiliates in the U.S. Our finance operations are located in the U.S. and Puerto Rico with earning assets principally sourced through Toyota, Lexus, and private label dealers. As of March 31, 2022, approximately 22 percent of retail and lease contracts were concentrated in California, 12 percent in Texas, 7 percent in New York, and 5 percent in New Jersey. Our voluntary protection operations are located in the U.S. As of March 31, 2022, approximately 25 percent of voluntary protection contracts were concentrated in California, 6 percent in New York, and 5 percent in Maryland and Virginia, respectively. Any material adverse changes to the economies or applicable laws in these states could have an adverse effect on our financial condition and results of operations. Note 1 – Basis of Presentation and Significant Accounting Policies (Continued) Other Matters In fiscal 2021, TMCC began providing private label financial services to third-party automotive and mobility companies commencing with the provision of services to Mazda Motor of America, Inc. (“Mazda”). We are currently leveraging our existing processes and personnel to originate and service the new assets; however, we will continue to evaluate the private label financial services business, which includes partnering with or transitioning a portion of the business to our affiliates, some of which are not consolidated with TMCC. We have also made certain technology investments to support the Mazda program and future private label customers. In fiscal 2021, we announced the restructuring of our customer service operations to better serve our customers by relocating and streamlining the customer service operation and investing in new technology. The restructuring is in progress and over the next year, we plan to complete the process of moving our three regional CSCs to be co-located with the regional DSCs to become regional experience centers. Costs associated with this restructure are not expected to be significant. On November 19, 2021, TMCC announced, in furtherance of its private label financial services initiative for third party automotive and mobility companies, that we entered into a nonbinding letter of intent with Great American Outdoors Group LLC, the parent company of Bass Pro Shops, Cabela’s and the White River Marine Group (“Bass Pro Shops”) to provide private label financial services for Bass Pro Shop’s boats, all-terrain vehicle products, and other mobility products. The Company expects to provide inventory financing for Bass Pro Shops, its affiliates, and authorized independent dealers, starting in fiscal 2023, with additional private label services, including consumer financing and voluntary protection products and services, to be added over time. Note 1 – Basis of Presentation and Significant Accounting Policies (Continued) Basis of Presentation and Principles of Consolidation Our accounting and financial reporting policies conform to accounting principles generally accepted in the United States of America (“U.S. GAAP”). Related party transactions presented in the Consolidated Financial Statements are disclosed in Note 12 – Related Party Transactions. The consolidated financial statements include the accounts of TMCC, its wholly-owned subsidiaries and all variable interest entities (“VIE”) of which we are the primary beneficiary. All intercompany transactions and balances have been eliminated. Use of Estimates 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 the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Because of inherent uncertainty involved in making estimates, actual results could differ from those estimates and assumptions. The accounting estimates that are most important to our business are the accumulated depreciation related to our investments in operating leases and the allowance for credit losses. Significant Accounting Policies Our significant accounting policies are found in the respective Note for which the policy is applicable. Recently Adopted Accounting Guidance In fiscal 2021, we adopted Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments Refer to Note 2 – Investments in Marketable Securities, Note 3 – Finance Receivables, Net, and Note 4 – Allowance for Credit Losses for additional information. In conjunction with the adoption of ASU 2016-13, we updated our depreciation policy for operating leases so that the useful life of the vehicles incorporates our historical experience on early terminations due to customer defaults. As a result, we changed the presentation for reporting early termination expenses related to customer defaults on investments in operating leases. We now present the effects of operating lease early terminations as part of accumulated depreciation within Investments in operating leases, net in the Consolidated Balance Sheets and Depreciation on operating leases in the Consolidated Statements of Income. The comparative period’s information continues to be reported under the relevant accounting presentation in effect for that period. Refer to Note 5 – Investments in Operating Leases, Net for additional information. Note 1 – Basis of Presentation and Significant Accounting Policies (Continued) On April 1, 2021, we adopted the following new accounting standards: We adopted Accounting Standards Update (“ASU”) 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, We adopted ASU 2020-08, Codification Improvements to Subtopic 310-20, Receivables-Nonrefundable Fees and Other Costs Accounting Guidance Issued But Not Yet Adopted In July 2021, the FASB issued ASU 2021-05, Lessors-Certain Leases with Variable Lease Payments (Topic 842) In March 2022, the FASB issued ASU 2022-02, Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures Financial Instruments – Credit Losses (Topic 326 Measurement of Credit Losses on Financial Instruments

Marketable Securities [Abstract]
Cash and Cash Equivalents and Investments in Marketable Securities	Note 2 – Cash and Cash Equivalents and Investments in Marketable Securities Cash and cash equivalents Cash and cash equivalents represent highly liquid investments with maturities of three months or less from the date of acquisition and may include money market instruments, commercial paper, certificates of deposit, U.S. government and agency obligations, or similar instruments. Restricted cash and cash equivalents Restricted cash and cash equivalents include customer collections on securitized receivables to be distributed to investors as payments on the related secured notes and loans payable, which are primarily related to securitization trusts. Restricted cash equivalents may also contain proceeds from certain debt issuances for which the use of the cash is restricted. Investments in marketable securities Investments in marketable securities consist of debt securities and equity investments. We classify all of our debt securities as available-for-sale (“AFS”). Except when the fair value option is elected, AFS debt securities are recorded at fair value with unrealized gains or losses included in accumulated other comprehensive income (“AOCI”), net of applicable taxes. Realized gains and losses from sales of AFS debt securities are determined using the specific identification method or first in first out method and are included in Investment and other income, net in our Consolidated Statements of Income. In fiscal 2021, we adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments In fiscal 2022, we have elected the fair value option for certain debt securities held within one of our affiliate investment portfolios for operational ease given the size and composition of this portfolio. All debt securities within this specific portfolio are recorded at fair value with changes in fair value included in Investment and other income, net in our Consolidated Statements of Income. AFS debt securities for which the fair value option is elected are not subject to credit loss impairment. As of March 31, 2022, we held AFS debt securities for which the fair value option was elected of $674 million. The difference between the aggregate fair value and the aggregate unpaid principal balance of long-term AFS debt securities for which the fair value option was elected was not significant. All equity investments are recorded at fair value with changes in fair value included in Investment and other income, net in our Consolidated Statements of Income. Realized gains and losses from sales of equity investments are determined using the first in first out method and are included in Investment and other income, net in our Consolidated Statements of Income.

If we elect to redeem shares, the Trust will normally redeem all shares for cash, but may, in unusual circumstances, redeem amounts exceeding the lesser of $250 thousand or 1 percent of the Trust’s asset value by payment in kind of securities held by the respective fund during any 90-day period. We also invest in actively traded open-end mutual funds. Redemptions are subject to normal terms and conditions as described in each fund’s prospectus. Non-cash investing activities related to in-kind redemptions and subsequent purchases amounted to $1.1 billion in fiscal 2022. We had no non-cash investing activities related to in-kind redemptions in fiscal 2021. Note 2 – Cash and Cash Equivalents and Investments in Marketable Securities (Continued) Unrealized Losses on Securities Available-for-sale debt securities in a continuous loss position for greater than twelve months were not significant as of March 31, 2022 and 2021.

Receivables [Abstract]
Finance Receivables, Net	Note 3 – Finance Receivables, Net Finance receivables, net consists of retail loan and dealer products portfolio segments, and includes deferred origination costs, deferred income, and allowance for credit losses. Finance receivables, net also includes securitized retail receivables, which represent retail receivables that have been sold for legal purposes to securitization trusts but continue to be included in our consolidated financial statements, as discussed further in Note 8 – Variable Interest Entities. Cash flows from these securitized retail receivables are available only for the repayment of debt issued by these trusts and other obligations arising from the securitization transactions. They are not available for payment of our other obligations or to satisfy claims of our other creditors. Finance receivables are classified as held-for-investment if the Company has the intent and ability to hold the receivables for the foreseeable future or until maturity or payoff. As of March 31, 2022 and 2021, all finance receivables were classified as held-for-investment. Revenues associated with retail and dealer financing are recognized to approximate a constant effective yield over the contract term. Incremental direct fees and costs incurred in connection with the acquisition of retail contracts and dealer financing receivables, including incentive and rate participation payments made to dealers, are capitalized and amortized to approximate a constant effective yield over the term of the related contracts. Payments received on subvention and other consumer incentives are deferred and recognized to approximate a constant effective yield over the term of the related contracts. Accrued interest related to finance receivables are presented within Other assets on the Consolidated Balance Sheet and was $214 million and $187 million at March 31, 2022 and 2021, respectively. For both retail loan and dealer products portfolio segments, accrued interest, deferred income, and deferred origination costs, if any, are written off within Provision for credit losses at the earlier of when an account is deemed to be uncollectible or when an account is greater than 120 days past due. Finance receivables, net consisted of the following: March 31, March 31, 2022 2021 Retail receivables 1 $ 73,152 $ 66,991 Dealer financing 10,298 13,642 83,450 80,633 Deferred origination costs 1,330 1,145 Deferred income (1,102 ) (1,408 ) Allowance for credit losses Retail receivables (1,195 ) (1,075 ) Dealer financing (51 ) (103 ) Total allowance for credit losses (1,246 ) (1,178 ) Finance receivables, net $ 82,432 $ 79,192 1 Note 3 – Finance Receivables, Net (Continued) Credit Quality Indicators We are exposed to credit risk on our finance receivables. Credit risk is the risk of loss arising from the failure of customers or dealers to meet the terms of their contracts with us or otherwise fail to perform as agreed. Retail Loan Portfolio Segment The retail loan portfolio segment consists of one class of finance receivables. While we use various credit quality metrics to develop our allowance for credit losses on the retail loan portfolio segment, we primarily utilize the aging of the individual accounts to monitor the credit quality of these finance receivables. Based on our experience, the payment status of borrowers is the strongest indicator of the credit quality of the underlying receivables. Payment status also impacts charge-offs. Individual borrower accounts within the retail loan portfolio segment are segregated into aging categories based on the number of days past due. The aging of finance receivables is updated monthly. The following tables present the amortized cost basis of our retail loan portfolio by origination fiscal year by credit quality indicator based on number of days past due: Amortized Cost Basis by Origination Fiscal Year at March 31, 2022 2022 2021 2020 2019 2018 2017 and Prior Total Aging of finance receivables: Current $ 32,382 $ 21,917 $ 9,624 $ 4,774 $ 2,674 $ 718 $ 72,089 30-59 days past due 275 304 153 101 63 36 932 60-89 days past due 68 82 40 25 16 11 242 90 days or greater past due 33 39 17 13 8 7 117 Total $ 32,758 $ 22,342 $ 9,834 $ 4,913 $ 2,761 $ 772 $ 73,380 Amortized Cost Basis by Origination Fiscal Year at March 31, 2021 2021 2020 2019 2018 2017 2016 and Prior Total Aging of finance receivables: Current $ 32,026 $ 16,047 $ 8,972 $ 5,977 $ 2,435 $ 496 $ 65,953 30-59 days past due 147 145 114 83 46 27 562 60-89 days past due 37 39 28 21 11 8 144 90 days or greater past due 18 18 13 9 5 6 69 Total $ 32,228 $ 16,249 $ 9,127 $ 6,090 $ 2,497 $ 537 $ 66,728 The amortized cost of retail loan portfolio excludes accrued interest of $192 million and $160 million at March 31, 2022 and 2021, respectively. The previous tables include contracts greater than 120 days past due, which are recorded at the fair value of collateral less estimated costs to sell, and contracts in bankruptcy. Note 3 – Finance Receivables, Net (Continued) Dealer Products Portfolio Segment The dealer products portfolio segment consists of three classes of finance receivables: wholesale, real estate and working capital. All loans outstanding for an individual dealer or dealer group, which includes affiliated entities, are aggregated and evaluated collectively by dealer or dealer group. This reflects the interconnected nature of financing provided to our individual dealer and dealer group customers, and their affiliated entities. When assessing the credit quality of the finance receivables within the dealer products portfolio segment, we segregate the finance receivables account balances into four categories representing distinct credit quality indicators based on internal risk assessments. The internal risk assessments for all finance receivables within the dealer products portfolio segment are updated on a monthly basis. The four credit quality indicators are: • Performing – Account not classified as either Credit Watch, At Risk or Default; • Credit Watch – Account designated for elevated attention; • At Risk – Account where there is an increased likelihood that default may exist based on qualitative and quantitative factors; and • Default – Account is not currently meeting contractual obligations or we have temporarily waived certain contractual requirements The following tables present the amortized cost basis of our dealer products portfolio by credit quality indicator based on internal risk assessments by origination fiscal year: Amortized Cost Basis by Origination Fiscal Year at March 31, 2022 2022 2021 2020 2019 2018 2017 and Prior Revolving loans Total Wholesale Performing $ - $ - $ - $ - $ - $ - $ 2,927 $ 2,927 Credit Watch - - - - - - 16 16 At Risk - - - - - - - - Default - - - - - - - - Wholesale total $ - $ - $ - $ - $ - $ - $ 2,943 $ 2,943 Real estate Performing $ 1,614 $ 1,245 $ 264 $ 384 $ 260 $ 1,245 $ - $ 5,012 Credit Watch 2 - - - - 5 - 7 At Risk - - - - - - - - Default - - - - - - - - Real estate total $ 1,616 $ 1,245 $ 264 $ 384 $ 260 $ 1,250 $ - $ 5,019 Working Capital Performing $ 662 $ 321 $ 209 $ 158 $ 37 $ 173 $ 774 $ 2,334 Credit Watch 1 1 - - - - - 2 At Risk - - - - - - - - Default - - - - - - - - Working capital total $ 663 $ 322 $ 209 $ 158 $ 37 $ 173 $ 774 $ 2,336 Total $ 2,279 $ 1,567 $ 473 $ 542 $ 297 $ 1,423 $ 3,717 $ 10,298 Note 3 – Finance Receivables, Net (Continued) Amortized Cost Basis by Origination Fiscal Year at March 31, 2021 2021 2020 2019 2018 2017 2016 and Prior Revolving loans Total Wholesale Performing $ - $ - $ - $ - $ - $ - $ 5,893 $ 5,893 Credit Watch - - - - - - 218 218 At Risk - - - - - - 35 35 Default - - - - - - 11 11 Wholesale total $ - $ - $ - $ - $ - $ - $ 6,157 $ 6,157 Real estate Performing $ 1,874 $ 320 $ 596 $ 356 $ 312 $ 1,493 $ - $ 4,951 Credit Watch 8 49 3 20 9 99 - 188 At Risk 13 - - - 12 17 - 42 Default - - - 13 9 - - 22 Real estate total $ 1,895 $ 369 $ 599 $ 389 $ 342 $ 1,609 $ - $ 5,203 Working Capital Performing $ 503 $ 334 $ 200 $ 41 $ 106 $ 176 $ 878 $ 2,238 Credit Watch 1 - 6 1 - 19 9 36 At Risk 1 - - - 7 - - 8 Default - - - - - - - - Working capital total $ 505 $ 334 $ 206 $ 42 $ 113 $ 195 $ 887 $ 2,282 Total $ 2,400 $ 703 $ 805 $ 431 $ 455 $ 1,804 $ 7,044 $ 13,642 The amortized cost of the dealer products portfolio excludes accrued interest of $22 million and $27 million at March 31, 2022 and 2021, respectively. As of March 31, 2022 and 2021, the amount of line-of-credit arrangements that are converted to term loans in each reporting period was insignificant, respectively. Note 3 – Finance Receivables, Net (Continued) Past Due Finance Receivables by Class Substantially all finance receivables do not involve recourse to the dealer in the event of customer default. Finance receivables include contracts greater than 120 days past due, which are recorded at the fair value of collateral less estimated costs to sell, and contracts in bankruptcy. Contracts for which vehicles have been repossessed are excluded. For all finance receivables, we define “past due” as any payment, including principal and interest, that is at least 30 days past the contractual due date. For any customer who is granted a payment extension under an extension program, the aging of the receivable is adjusted for the number of days of the extension granted. The following tables presents the aging of the amortized cost basis of our finance receivables by class: March 31, 2022 30 - 59 Days past due 60 - 89 Days past due 90 Days or greater past due Total Past due Current Total Finance receivables 90 Days or greater past due and accruing Retail loan $ 932 $ 242 $ 117 $ 1,291 $ 72,089 $ 73,380 $ 65 Wholesale - - - - 2,943 2,943 - Real estate - - - - 5,019 5,019 - Working capital - - - - 2,336 2,336 - Total $ 932 $ 242 $ 117 $ 1,291 $ 82,387 $ 83,678 $ 65 March 31, 2021 30 - 59 Days past due 60 - 89 Days past due 90 greater past due Total due Current Total receivables 90 greater p due and accruing Retail loan $ 562 $ 144 $ 69 $ 775 $ 65,953 $ 66,728 $ 39 Wholesale - - - - 6,157 6,157 - Real estate - - - - 5,203 5,203 - Working capital - - - - 2,282 2,282 - Total $ 562 $ 144 $ 69 $ 775 $ 79,595 $ 80,370 $ 39 Note 3 – Finance Receivables, Net (Continued) Troubled Debt Restructuring A troubled debt restructuring occurs when a finance receivable is modified through a concession to a borrower experiencing financial difficulty. A finance receivable modified under a troubled debt restructuring is considered to be impaired. In addition, troubled debt restructurings include finance receivables for which the customer has filed for bankruptcy protection. For such finance receivables, we no longer have the ability to modify the terms of the agreement without the approval of the bankruptcy court and the court may impose term modifications that we are obligated to accept. For accounts not under bankruptcy protection, the amount of finance receivables modified as a troubled debt restructuring during fiscal 2022 and 2021 was not significant for each class of finance receivables. Troubled debt restructurings for accounts not under bankruptcy protection within the retail loan class of finance receivables are comprised exclusively of contract term extensions that reduce the monthly payment due from the customer. For the three classes of finance receivables within the dealer products portfolio segment, troubled debt restructurings include contract term extensions, interest rate adjustments, waivers of loan covenants, or any combination of the three. Troubled debt restructurings of accounts not under bankruptcy protection did not include forgiveness of principal or interest rate adjustments during fiscal 2022 and 2021. We consider finance receivables under bankruptcy protection within the retail loan class to be troubled debt restructurings as of the date we receive notice of a customer filing for bankruptcy protection, regardless of the ultimate outcome of the bankruptcy proceedings. The bankruptcy court may impose modifications as part of the proceedings, including interest rate adjustments and forgiveness of principal. For fiscal 2022 and 2021, the financial impact of troubled debt restructurings related to finance receivables under bankruptcy protection was not significant to our Consolidated Statements of Income and Consolidated Balance Sheets. For a limited time during fiscal 2021, we offered several programs to provide relief to customers during the COVID-19 pandemic. These programs, which were broadly available to our customers, included retail loan payment extensions and lease payment deferrals. We concluded that these programs did not meet troubled debt restructuring criteria due to the short-term nature of the modifications with no change in the contractual interest rate. To provide relief for our dealers we offered certain temporary interest reductions, interest payment deferrals, and interest waivers on dealer floorplan financing, and principal payment deferrals on dealer floorplan financing, dealer real estate and working capital loans. We also concluded that these programs did not meet troubled debt restructuring criteria as the finance receivables from the dealers were current.

Allowance for Credit Losses

Allowance for Credit Losses	Mar. 31, 2022
Loans And Leases Receivable Disclosure [Abstract]
Allowance for Credit Losses	Note 4 – Allowance for Credit Losses Upon adoption of ASU 2016-13 in fiscal 2021, the incurred loss impairment method was replaced with a new impairment model that reflects lifetime expected losses. Management develops and documents the allowance for credit losses on finance receivables based on two portfolio segments. The determination of portfolio segments is based primarily on the qualitative consideration of the nature of our business operations and the characteristics of the underlying finance receivables, as follows: • Retail Loan Portfolio Segment – The retail loan portfolio segment consists of retail contracts acquired from dealers in the U.S. and Puerto Rico. Under a retail contract, we are granted a security interest in the underlying collateral which consists primarily of Toyota, Lexus, and private label vehicles. Based on the common risk characteristics associated with the finance receivables, the retail loan portfolio segment is considered a single class of finance receivable. • Dealer Products Portfolio Segment – The dealer products portfolio segment consists of wholesale financing, working capital loans, revolving lines of credit and real estate loans to dealers in the U.S. and Puerto Rico. Wholesale financing is primarily collateralized by new or used vehicle inventory with the outstanding balance fluctuating based on the level of inventory. Working capital loans and revolving lines of credit are granted for working capital purposes and are secured by dealership assets. Real estate loans are collateralized by the underlying real estate, are underwritten primarily on a loan-to-value basis and are typically for a fixed term. Based on the risk characteristics associated with the underlying finance receivables, the dealer products portfolio segment consists of three classes of finance receivables: wholesale, working capital (including revolving lines of credit), and real estate. Management’s estimate of lifetime expected credit losses is based on an evaluation of relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the future collectability of the finance receivables. Management’s evaluation takes into consideration the risks in the retail loan portfolio and dealer products portfolio, past loss experience, delinquency trends, underwriting and collection practices, changes in portfolio composition, economic forecasts and other relevant factors. Methodology Used to Develop the Allowance for Credit Losses The allowance for credit losses is measured on a collective basis when loans have similar risk characteristics. Loans that do not share similar risk characteristics are evaluated on an individual basis. We generally use a discounted cash flow approach for determining allowance for credit losses for finance receivables modified as a troubled debt restructuring that are granted with interest rate concessions, and a non-discounted cash flow approach for other loans. We measure expected losses of all components of finance receivables on an amortized cost basis, excluding accrued interest, and including off-balance-sheet lending commitments that are not unconditionally cancellable by TMCC. Estimated expected credit losses for off-balance-sheet lending commitments within our dealer products portfolio are included in Other liabilities on the Consolidated Balance Sheets. We have elected to exclude accrued interest from the measurement of expected credit losses as we apply policies and procedures that result in the timely write-offs of accrued interest. Accrued interest is written off within allowance for credit losses at the earlier of when an account is deemed to be uncollectible or when an account is greater than 120 days past due. Retail Loan Portfolio Segment The level of credit risk in our retail loan portfolio segment is influenced by various factors such as economic conditions, the used vehicle market, credit quality, contract structure, and collection strategies and practices. The allowance for credit losses is measured on a collective basis when loans have similar risk characteristics such as loan-to-value ratio, book payment-to-income ratio, FICO score at origination, collateral type, contract term, and other relevant factors. We use statistical models to estimate lifetime expected credit losses of our retail loan portfolio segment by applying probability of default and loss given default to the exposure at default on a loan level basis. Probability of default models are developed from internal risk scoring models which consider variables such as delinquency status, historical default frequency, and other credit quality indicators such as loan-to-value ratio, book payment-to-income ratio, FICO score at origination, collateral type (new or used, Lexus, Toyota, or private label), and contract term. Note 4 – Allowance for Credit Losses (Continued) Loss given default models forecast the extent of losses given that a default has occurred and considers variables such as collateral, trends in recoveries, historical loss severity, and other contract structure variables. Exposure at default represents the expected outstanding principal balance, including the effects of expected prepayment when applicable. The lifetime expected credit losses incorporate the probability-weighted forward-looking macroeconomic forecasts for baseline, favorable, and adverse scenarios. The loan lifetime is regarded by management as the reasonable and supportable period. We use macroeconomic forecasts from a third party and update such forecasts quarterly. On an ongoing basis, we review our models, including macroeconomic factors, the selection of macroeconomic scenarios and their weighting to ensure they reflect the risk of the portfolio. If management does not believe the models reflect lifetime expected credit losses, a qualitative adjustment is made to reflect management judgment regarding observable changes in recent or expected economic trends and conditions, portfolio composition, and other relevant factors. While management uses the best information available to make such evaluations, future adjustments to the allowance for credit losses may be necessary if conditions differ substantially from the assumptions used in making the evaluations. Dealer Products Portfolio Segment The level of credit risk in our dealer products portfolio segment is influenced primarily by the financial strength of dealers within our portfolio, dealer concentration, collateral quality, and other economic factors. The financial strength of dealers within our portfolio is influenced by, among other factors, general economic conditions, the overall demand for new and used vehicles and the financial condition of automotive manufacturers. The allowance for credit losses is established for both outstanding dealer finance receivables and certain unfunded off-balance sheet lending commitments. The allowance for credit losses is measured on a collective basis when loans have similar risk characteristics such as dealer group internal risk rating and loan-to-value ratios. We measure lifetime expected credit losses of our dealer products portfolio segment by applying probability of default and loss given default to the exposure at default on a loan level basis. Probability of default is primarily established based on internal risk assessments. The probability of default model also considers qualitative factors related to macroeconomic outlooks. Loss given default is established based on the nature and market value of the collateral, loan-to-value ratios and other credit quality indicators. Exposure at default represents the expected outstanding principal balance. The lifetime of the loan or lending commitment is regarded by management as the reasonable and supportable period. On an ongoing basis, we review our models, including macroeconomic outlooks, to ensure they reflect the risk of the portfolio. If management does not believe the models reflect lifetime expected credit losses, a qualitative adjustment is made to reflect management judgment regarding observable changes in recent or expected economic trends and conditions, portfolio composition, and other relevant factors. While management uses the best information available to make such evaluations, future adjustments to the allowance for credit losses may be necessary if conditions differ substantially from the assumptions used in making the evaluations. Accounting for the Allowance for Credit Losses Increases to the allowance for credit losses are accompanied by corresponding charges to the Provision for credit losses in our Consolidated Statements of Income. The uncollectible portion of finance receivables is charged to the allowance for credit losses at the earlier of when an account is deemed to be uncollectible or when an account is greater than 120 days past due. In the event we repossess the collateral, the receivable is charged-off and we record the collateral at its estimated fair value less costs to sell and report it in Other assets on our Consolidated Balance Sheets. Recoveries of finance receivables previously charged off as uncollectible are credited to the allowance for credit losses. Note 4 – Allowance for Credit Losses (Continued) The following tables provide information related to our allowance for credit losses for finance receivables and certain off-balance sheet lending commitments by portfolio segment: Year ended March 31, 2022 Retail loan Dealer p Total Beginning balance, April 1, 2021 $ 1,075 $ 140 $ 1,215 Charge-offs (237 ) - (237 ) Recoveries 58 - 58 Provision for credit losses 299 (63 ) 236 Ending balance, March 31, 2022 1 $ 1,195 $ 77 $ 1,272 1 Ending balance includes $26 million of allowance for credit losses related to off-balance sheet commitments in the dealer products portfolio which is included in Other liabilities on the Consolidated Balance Sheet.

(“TMNA”), and $187 million in finance receivables that are guaranteed by third-party private Toyota distributors. Finance receivables for the dealer products portfolio segment as of March 31, 2021 includes $1,028 million in finance receivables that are guaranteed by TMNA, and $162 million in finance receivables that are guaranteed by third-party private Toyota distributors. These finance receivables are related to certain Toyota and Lexus dealers and other third parties to whom we provided financing at the request of TMNA and third-party private Toyota distributors. During fiscal 2022, the allowance for credit losses increased $57 million primarily due to the increase in size of our retail loan portfolio and an increase in delinquencies, as well as the economic conditions caused by the conflict in Ukraine, partially offset by continued improved dealer financial performance in fiscal 2022. In contrast, in fiscal 2021, the allowance for credit losses increased $488 million, reflecting an increase to the allowance for credit losses of $292 million related to the adoption of ASU 2016-13 in fiscal 2021, and an increase of $196 million primarily due to an increase in the size of the portfolio and the increase in expected credit losses for the retail loan portfolio driven by economic conditions caused by the COVID-19 pandemic and the restrictions designed to slow the spread of COVID-19, including stay-at-home orders, increased unemployment, and decreased consumer spending.

Investments in Operating Leases, Net	Mar. 31, 2022
Leases Operating [Abstract]
Investments in Operating Leases, Net	Note 5 – Investments in Operating Leases, Net Investments in operating leases, net consists of vehicle lease contracts acquired from dealers, and includes deferred origination fees and costs, deferred income, and accumulated depreciation. Generally, lessees have the ability to extend their lease term in six month increments up to a total of 12 months from the original lease maturity date. A lease can be terminated at any time by satisfying the obligations under the lease contract. Early termination programs may be occasionally offered to eligible lessees. At the end of the lease, the customer has the option to buy the leased vehicle or return the vehicle to the dealer. Securitized investments in operating leases represent beneficial interests in a pool of certain vehicle leases that have been sold for legal purposes to securitization trusts but continue to be included in our consolidated financial statements as discussed further in Note 8 - Variable Interest Entities. Cash flows from these securitized investments in operating leases are available only for the repayment of debt issued by these trusts and other obligations arising from the securitization transactions. They are not available for payment of our other obligations or to satisfy claims of our other creditors. Operating lease revenues are recognized on a straight-line basis over the term of the lease. We have made an accounting policy election to exclude from the consideration in the contract, and from variable payments not included in the consideration in the contract, sales and other taxes assessed by a governmental authority that are both imposed on and concurrent with a specific lease revenue-producing transaction and collected from customers. Deferred fees and costs include incentive payments made to dealers and acquisition fees collected from customers. Deferred income includes payments received on affiliate sponsored subvention and other incentive programs. Both deferred fees and costs and deferred income are capitalized or deferred and amortized on a straight-line basis over the contract term. The accrual of revenue on investments in operating leases is discontinued at the time an account is determined to be uncollectible and subsequent revenue is recognized only to the extent a payment is received. Operating leases may be restored to accrual status when future payments are reasonably assured. Vehicle Lease Residual Values Contractual residual values of vehicle lease contracts are estimated at lease inception by examining external industry data, the anticipated Toyota, Lexus, and private label product pipeline and our own experience. Factors considered in this evaluation include macroeconomic forecasts, new vehicle pricing, new vehicle incentive programs, new vehicle sales, vehicle features and specifications, the mix and level of used vehicle supply, the level of current used vehicle values, and fuel prices. We are exposed to a risk of loss to the extent the customer returns the vehicle and the value of the vehicle is lower than the residual value estimated at inception of the lease or if the number of returned vehicles is higher than anticipated. Depreciation on operating leases is recognized using the straight-line method over the lease term. The depreciable basis is the original acquisition cost of the vehicle less the estimated residual value of the vehicle at the end of the lease term. On a quarterly basis, we review the estimated end-of-term market values and return rates of leased vehicles to assess the appropriateness of the carrying values at lease-end. Factors affecting the estimated end-of-term market value are similar to those considered in the evaluation of residual values at lease inception discussed above. Adjustments to depreciation expense to reflect revised estimates of expected market values at lease termination and revised return rates are recorded prospectively on a straight-line basis over the remaining lease term. We use various channels to sell vehicles returned at lease-end. Upon disposition, the difference between the net book value of the lease and the proceeds received from the disposition of the asset, including any insurance proceeds is recorded as an adjustment to depreciation on operating leases. We evaluate our investment in operating leases portfolio for potential impairment when we determine a triggering event has occurred. When a triggering event has occurred, we perform a test of recoverability by comparing the expected undiscounted future cash flows (including expected residual values) over the remaining lease terms to the carrying value of the asset group. If the test of recoverability identifies a possible impairment, the asset group’s fair value is measured in accordance with the fair value measurement framework. An impairment charge would be recognized for the amount by which the carrying value of the asset group exceeds its estimated fair value and would be recorded in our Consolidated Statements of Income. As of March 31, 2022 and 2021, there was no impairment in our investment in operating leases portfolio. Note 5 – Investments in Operating Leases, Net (Continued) Our depreciation policy for operating leases incorporates our historical experience on early terminations due to customer defaults into the useful live of the vehicles. We consider the effects of operating lease early terminations when determining depreciation estimates, which are included as part of accumulated depreciation within Investments in operating leases, net on the Consolidated Balance Sheets and Depreciation on operating leases in the Consolidated Statements of Income. Investments in operating leases, net consisted of the following: March 31, March 31, 2022 2021 Investments in operating leases 1 $ 45,728 $ 48,337 Deferred origination (fees) and costs, net (46 ) (101 ) Deferred income (1,272 ) (1,759 ) Accumulated depreciation (8,955 ) (9,386 ) Investments in operating leases, net $ 35,455 $ 37,091 1 Future minimum rentals on investments in operating leases are as follows: Years ending March 31, Future minimum rentals on operating leases 2023 $ 5,604 2024 3,620 2025 1,073 2026 83 2027 8 Thereafter - Total $ 10,388 A portion of our operating lease contracts has historically terminated prior to maturity.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives, Hedging Activities and Interest Expense	Note 6 – Derivatives, Hedging Activities and Interest Expense Derivative Instruments Our liabilities consist mainly of fixed and variable rate debt, denominated in U.S. dollars and various other currencies, which we issue in the global capital markets, while our assets consist primarily of U.S. dollar denominated, fixed rate receivables. We enter into interest rate swaps and foreign currency swaps to economically hedge the interest rate and foreign currency risks that result from the different characteristics of our assets and liabilities. Our use of derivative transactions is intended to reduce long-term fluctuations in the fair value of assets and liabilities caused by market movements. All of our derivatives are categorized as not designated for hedge accounting, and all of our derivative activities are authorized and monitored by our management and our Asset-Liability Committee which provides a framework for financial controls and governance to manage market risk. All derivative instruments are recorded on the balance sheet at fair value, taking into consideration the effects of legally enforceable master netting agreements that allow us to net settle asset and liability positions and offset cash collateral with the same counterparty on a net basis. Changes in the fair value of our derivative instruments are recorded in Interest expense in our Consolidated Statements of Income. The derivative instruments are included as a component of Other assets or Other liabilities on our Consolidated Balance Sheets. Offsetting of Derivatives Accounting guidance permits the net presentation on our Consolidated Balance Sheets of derivative receivables and derivative payables with the same counterparty and the related cash collateral when a legally enforceable master netting agreement exists, or when the derivative receivables and derivative payables meet all the conditions for the right of setoff to exist. When we meet this condition, we elect to present such balances on a net basis. Over-the-Counter (“OTC”) Derivatives Our International Swaps and Derivatives Association Master Agreements are our master netting agreements which permit multiple transactions to be cancelled and settled with a single net balance paid to either party for our OTC derivatives. The master netting agreements also contain reciprocal collateral agreements which require the transfer of cash collateral to the party in a net asset position across all transactions. Our collateral agreements with substantially all our counterparties include a zero threshold, full collateralization arrangement. Although we have daily valuation and collateral exchange arrangements with all of our counterparties, due to the time required to move collateral, there may be a delay of up to one day between the exchange of collateral and the valuation of our derivatives. We would not be required to post additional collateral to the counterparties with whom we were in a net liability position at March 31, 2022, if our credit ratings were to decline, since we fully collateralize without regard to credit ratings with these counterparties. In addition, as our collateral agreements include legal right of offset provisions, collateral amounts are netted against derivative assets or derivative liabilities, and the net amount is included in Other assets or Other liabilities on our Consolidated Balance Sheets. Centrally Cleared Derivatives For our centrally cleared derivatives, variation margin payments are legally characterized as settlement payments and accounted for with corresponding derivative positions as one unit of account as opposed to collateral. Initial margin payments are separately recorded in Other assets on our Consolidated Balance Sheets. We perform valuation and margin exchange on a daily basis. Similar to the OTC swaps, there may be a delay of up to one day between the exchange of margin payments and the valuation of our derivatives.

Debt and Credit Facilities	Note 7 – Debt and Credit Facilities Debt and the related weighted average contractual interest rates are summarized as follows: March 31, 2022 March 31, 2021 Face value Carrying value Weighted average contractual interest rates Face value Carrying value Weighted average contractual interest rates Unsecured notes and loans payable $ 82,542 $ 82,288 1.30 % $ 85,759 $ 85,513 1.31 % Secured notes and loans payable 26,907 26,864 1.01 % 24,256 24,212 1.29 % Total debt $ 109,449 $ 109,152 1.23 % $ 110,015 $ 109,725 1.31 % The carrying value of our debt includes unamortized premiums, discounts, debt issuance costs and the effects of foreign currency translation adjustments. Debt issuance costs are deferred and amortized to interest expense on an effective yield basis over the contractual term of the debt. Weighted average contractual interest rates are calculated based on original notional or par value before consideration of premium or discount and approximate the effective interest rates. Debt is callable at par value. Scheduled maturities of our debt portfolio are summarized below. Actual repayment of secured debt will vary based on the repayment activity on the related pledged assets. Future Years ending March 31, debt maturities 2023 $ 51,171 2024 20,889 2025 13,466 2026 9,642 2027 7,279 Thereafter 1 7,002 Unamortized premiums, discounts and debt issuance costs (297 ) Total debt $ 109,152 1 Unsecured and secured notes and loans payable mature on various dates through fiscal 2049. Unsecured Notes and Loans Payable Our unsecured notes and loans payable consist of commercial paper and fixed and variable rate debt. Short-term funding needs are met through the issuance of commercial paper in the U.S. Amounts outstanding under our commercial paper programs were $16.9 billion and $17.0 billion as of March 31, 2022, and 2021, respectively. Upon issuance of fixed rate debt, we generally elect to enter into pay-float swaps to convert fixed rate payments on debt to floating rate payments. Certain unsecured notes and loans payable are denominated in various foreign currencies. The debt is translated into U.S. dollars using the applicable exchange rate at the transaction date and retranslated at each balance sheet date using the exchange rate in effect at that date. The resulting transaction gains and losses are included in Interest expense in our Consolidated Statements of Income. Concurrent with the issuance of these foreign currency unsecured notes and loans payable, we enter into currency swaps in the same notional amount to convert non-U.S. currency payments to U.S. dollar denominated payments. Gains and losses related to foreign currency transactions are included in Interest expense in our Consolidated Statements of Income. Certain of our unsecured notes and loans payable contain covenants and conditions customary in transactions of this nature, including negative pledge provisions, cross-default provisions and limitations on certain consolidations, mergers and sales of assets. We are currently in compliance with these covenants and conditions. Note 7 – Debt and Credit Facilities (Continued) Secured Notes and Loans Payable Our secured notes and loans payable are denominated in U.S. dollars and consist of both fixed and variable rate debt. Secured notes and loans payable are issued using on-balance sheet securitization trusts, as further discussed in Note 8 – Variable Interest Entities. These notes are repayable only from collections on the underlying securitized retail finance receivables and the beneficial interests in investments in operating leases and from related credit enhancements. Some of our secured notes are backed by a revolving pool of finance receivables and cash collateral, with the ability to repay the notes in full after the revolving period ends, after which an amortization period begins. Credit Facilities and Letters of Credit For additional liquidity purposes, we maintain credit facilities, which may be used for general corporate purposes, as described below: 364-Day Credit Agreement, Three-Year Credit Agreement and Five-Year Credit Agreement TMCC, Toyota Credit de Puerto Rico Corp. (“TCPR”), a wholly-owned subsidiary, and other Toyota affiliates are party to a $5.0 billion 364-day syndicated bank credit facility, $5.0 billion three-year syndicated bank credit facility and a $5.0 billion five-year syndicated bank credit facility, expiring in fiscal 2023, 2025, and 2027 respectively. The ability to make draws is subject to covenants and conditions customary in transactions of this nature, including negative pledge provisions, cross default provisions and limitations on certain consolidations, mergers and sales of assets. These agreements were not drawn upon and had no outstanding balances as March 31, 2022 and 2021. We are currently in compliance with the covenants and conditions of the credit agreements described above. Committed Revolving Asset-backed Facility We are party to a 364-day revolving securitization facility with certain bank-sponsored asset-backed conduits and other financial institutions expiring in fiscal 2023. Under the terms and subject to the conditions of this facility, the committed lenders under the facility have committed to make advances up to a facility limit of $7.0 billion backed by eligible retail finance receivables transferred by us to a special-purpose entity acting as borrower. We utilized $3.2 billion of this facility as of March 31, 2022 and 2021, respectively. Other Unsecured Credit Agreements TMCC is party to additional unsecured credit facilities with various banks. As of March 31, 2022, TMCC had committed bank credit facilities totaling $4.6 billion, of which $2.3 billion, $300 million, and $2.0 billion mature in fiscal 2023, 2024, and 2025 respectively. These credit agreements contain covenants and conditions customary in transactions of this nature, including negative pledge provisions, cross-default provisions and limitations on certain consolidations, mergers and sales of assets. These credit facilities were not drawn upon and had no outstanding balances as of March 31, 2022 and 2021. We are currently in compliance with the covenants and conditions of the credit agreements described above. TMCC is party to a $5.0 billion three-year revolving credit facility with Toyota Motor Sales, U.S.A., Inc. (“TMS”), expiring in fiscal 2025. This credit facility was not drawn upon and had no outstanding balance as of March 31, 2022 and 2021. From time to time, we may borrow from affiliates based upon a number of business factors such as funds availability, cash flow timing, relative cost of funds, and market access capabilities. Amounts borrowed from affiliates are recorded in Other liabilities on our Consolidated Balance Sheets.

Variable Interest Entities

Variable Interest Entities	Mar. 31, 2022
Variable Interest Entities [Abstract]
Variable Interest Entities	Note 8 – Variable Interest Entities A VIE is an entity that either (i) has insufficient equity to permit the entity to finance its activities without additional subordinated financial support or (ii) has equity investors who lack the characteristics of a controlling financial interest. The primary beneficiary of a VIE is the party with both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and the obligation to absorb the losses or the right to receive benefits that could potentially be significant to the VIE. To assess whether we have the power to direct the activities of a VIE that most significantly impact its economic performance, we consider all the facts and circumstances including our role in establishing the VIE and our ongoing rights and responsibilities. This assessment includes identifying the activities that most significantly impact the VIE’s economic performance and identifying which party, if any, has power over those activities. In general, the party that makes the most significant decisions affecting the VIE is determined to have the power to direct the activities of the VIE. To assess whether we have the obligation to absorb the losses or the right to receive benefits that could potentially be significant to the VIE, we consider all of our economic interests, including debt and equity interests, servicing rights and fee arrangements, and any other variable interests in the VIE. If we determine that we are the party with the power to make the most significant decisions affecting the VIE, and we have an obligation to absorb the losses or the right to receive benefits that could potentially be significant to the VIE, then we consolidate the VIE. We perform ongoing reassessments, usually quarterly, of whether we are the primary beneficiary of a VIE. The reassessment process considers whether we have acquired or divested the power to direct the most significant activities of the VIE through changes in governing documents or other circumstances. We also reconsider whether entities previously determined not to be VIEs have become VIEs, based on new events, and therefore could be subject to the VIE consolidation framework. Consolidated Variable Interest Entities We use one or more special purpose entities that are considered VIEs to issue asset-backed securities to third-party bank-sponsored asset-backed securitization vehicles and to investors in securitization transactions. The securities issued by these VIEs are backed by the cash flows related to retail finance receivables and beneficial interests in investments in operating leases (“Securitized Assets”). We hold variable interests in the VIEs that could potentially be significant to the VIEs. We determined that we are the primary beneficiary of the securitization trusts because (i) our servicing responsibilities for the Securitized Assets give us the power to direct the activities that most significantly impact the performance of the VIEs, and (ii) our variable interests in the VIEs give us the obligation to absorb losses and the right to receive residual returns that could potentially be significant. The following tables show the assets and liabilities related to our VIE securitization transactions that were included on our Consolidated Balance Sheets: March 31, 2022 VIE Assets VIE Liabilities Net Restricted cash securitized assets Other assets Debt Other liabilities Retail finance receivables $ 1,284 $ 20,932 $ 51 $ 18,562 $ 8 Investments in operating leases 645 11,886 15 8,302 2 Total $ 1,929 $ 32,818 $ 66 $ 26,864 $ 10 March 31, 2021 VIE Assets VIE Liabilities Net Restricted cash securitized assets Other assets Debt Other liabilities Retail finance receivables $ 1,521 $ 21,745 $ 46 $ 19,665 $ 13 Investments in operating leases 436 6,599 43 4,547 1 Total $ 1,957 $ 28,344 $ 89 $ 24,212 $ 14 Note 8 – Variable Interest Entities (Continued) Restricted cash, including cash equivalents, shown in the previous tables represent collections from the underlying Net securitized assets and certain reserve deposits held by TMCC for the VIEs and is included as part of Restricted cash and cash equivalents on our Consolidated Balance Sheets. Net securitized assets shown in the previous tables are presented net of deferred fees and costs, deferred income, accumulated depreciation, and allowance for credit losses. Other assets represent accrued interests related to securitized retail finance receivables and used vehicles held-for-sale that were repossessed by or returned to TMCC for the benefit of the VIEs. The related debt of these consolidated VIEs is presented net of $1,667 million and $1,409 million of securities retained by TMCC at March 31, 2022 and 2021, respectively. Other liabilities represent accrued interest on the debt of the consolidated VIEs. The assets of the VIEs and the Restricted cash and cash equivalents held by TMCC serve as the sole source of repayment for the asset-backed securities issued by these entities. Investors in the notes issued by the VIEs do not have recourse to us or our other assets, with the exception of customary representation and warranty repurchase provisions and indemnities. As the primary beneficiary of these entities, we are exposed to credit, residual value, interest rate, and prepayment risk from the Securitized Assets in the VIEs. However, our exposure to these risks did not change as a result of the transfer of the assets to the VIEs. We may also be exposed to interest rate risk arising from the secured notes issued by the VIEs. In addition, we entered into interest rate swaps with certain special purpose entities that issue variable rate debt. Under the terms of these swaps, the special purpose entities are obligated to pay TMCC a fixed rate of interest on certain payment dates in exchange for receiving a floating rate of interest on notional amounts equal to the outstanding balance of the secured debt. This arrangement enables the special purpose entities to mitigate the interest rate risk inherent in issuing variable rate debt that is secured by fixed rate Securitized Assets. The transfers of the Securitized Assets to the special purpose entities in our securitizations are considered to be sales for legal purposes. However, the Securitized Assets and the related debt remain on our Consolidated Balance Sheets. We recognize financing revenue on the Securitized Assets and interest expense on the secured debt issued by the special purpose entities. We also maintain an allowance for credit losses on the securitized retail finance receivables using a methodology consistent with that used for our non-securitized asset portfolio. The interest rate swaps between TMCC and the special purpose entities are considered intercompany transactions and therefore are eliminated in our consolidated financial statements. Non-consolidated Variable Interest Entities We provide lending to Toyota and Lexus dealers through the Toyota Dealer Investment Group’s Dealer Capital Program (“TDIG Program”) operated by our affiliate TMNA, which has an equity interest in these dealerships. Dealers participating in this program have been determined to be VIEs. We do not consolidate the dealerships in this program as we are not the primary beneficiary and any exposure to loss is limited to the amount of the credit facility. Amounts due from these dealers under the TDIG Program that are classified as Finance receivables, net on our Consolidated Balance Sheets at March 31, 2022 and 2021, and revenues earned from these dealers during fiscal 2022, 2021 and 2020 were not significant. We also have other lending relationships which have been determined to be VIEs, but these relationships are not consolidated as we are not the primary beneficiary. Amounts due from these lending relationships at March 31, 2022 and 2021, and revenues earned under these relationships during fiscal 2022, 2021, 2020 were not significant.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 9 – Commitments and Contingencies Commitments and Guarantees We have entered into certain commitments and guarantees for which the maximum unfunded amounts are summarized in the table below: March 31, March 31, 2022 2021 Commitments: Credit facilities commitments with dealers $ 3,289 $ 2,338 Commitments under operating lease agreements 119 141 Total commitments 3,408 2,479 Guarantees of affiliate pollution control and solid waste disposal bonds 100 100 Total commitments and guarantees $ 3,508 $ 2,579 Wholesale financing is not considered to be a contractual commitment as the arrangements are not binding arrangements under which TMCC is required to perform. Commitments We provide fixed and variable rate working capital loans, revolving lines of credit, and real estate financing to dealers and various multi-franchise organizations referred to as dealer groups for facilities construction and refurbishment, working capital requirements, real estate purchases, business acquisitions and other general business purposes. These loans are typically secured with liens on real estate, vehicle inventory, and/or other dealership assets, as appropriate, and may be guaranteed by individual or corporate guarantees of affiliated dealers, dealer groups, or dealer principals. Although the loans are typically collateralized or guaranteed, the value of the underlying collateral or guarantees may not be sufficient to cover our exposure under such agreements. Our pricing reflects market conditions, the competitive environment, the level of support dealers provide our retail, lease and voluntary protection business and the credit worthiness of each dealer. Amounts drawn under these facilities are reviewed for collectability on a quarterly basis, in conjunction with our evaluation of the allowance for credit losses. In addition to the total commitments and guarantees in the previous table, we have also extended credit facilities to affiliates as described in Note 12 – Related Party Transactions. Lease Commitments Our operating lease portfolio consists of real estate leases. Total operating lease expense, including payments to affiliates, was $32 million for fiscal 2022, $36 million for fiscal 2021, and $36 million fiscal 2020. We have a lease agreement through August 2032 with TMNA for our headquarters facility in Plano, Texas. Commitments under operating lease agreements in the table above include $84 million and $93 million for facilities leases with affiliates at March 31, 2022 and 2021, respectively. Lease terms may contain renewal and extension options or early termination features. Generally, these options do not impact the lease term because TMCC is not reasonably certain that it will exercise the options. These lease agreements do not impose restrictions on our ability to pay dividends, engage in debt or equity financing transactions or enter into further lease agreements, nor do they have residual value guarantees. We exclude from our Consolidated Balance Sheets leases with a term equal to one year or less and do not separate non-lease components from our real estate leases. Note 9 – Commitments and Contingencies (Continued) Our commitments under operating lease agreements are summarized below: March 31, Years ending March 31, 2022 2023 $ 19 2024 16 2025 14 2026 13 2027 12 Thereafter 45 Total $ 119 Present value discount (13 ) Total operating lease liability $ 106 Operating lease liabilities and right-of-use (“ROU”) assets are recognized at the lease commencement date based on the present value of the future minimum lease payments over the lease term. As the interest rate implicit in the lease contract is typically not readily determinable, we utilize our incremental borrowing rate at the lease commencement date for the duration of the lease term. The following table provides additional information related to operating lease agreements for which we are the lessee: March 31, 2022 ROU assets $ 97 Weighted average remaining lease term (in years) 8.3 Weighted average discount rate 2.76 % Supplemental cash flow information Cash paid for amounts included in the measurement of lease liabilities - operating cash flows $ 26 Guarantees and Other Contingencies TMCC has guaranteed bond obligations totaling $100 million in principal that were issued by Putnam County, West Virginia and Gibson County, Indiana to finance the construction of pollution control facilities at manufacturing plants of certain TMCC affiliates. The bonds mature in the following fiscal years ending March 31: 2028 - $20 million; 2029 - $50 million; 2030 - $10 million; 2031 - $10 million; and 2032 - $10 million. TMCC would be required to perform under the guarantees in the event of non-payment on the bonds and other related obligations. TMCC is entitled to reimbursement by the applicable affiliates for any amounts paid. TMCC receives a nominal annual fee for guaranteeing such payments. TMCC has not been required to perform under any of these affiliate bond guarantees as of March 31, 2022 and 2021. Note 9 – Commitments and Contingencies (Continued) Indemnification In the ordinary course of business, we enter into agreements containing indemnification provisions standard in the industry related to several types of transactions, including, but not limited to, debt funding, derivatives, securitization transactions, and our vendor, supplier and service agreements. Performance under these indemnities would generally occur upon a breach of the representations, warranties, covenants or other commitments made or given in the agreement, or as a result of a third-party claim. In addition, we have agreed in certain debt and derivative issuances, and subject to certain exceptions, to gross-up payments due to third parties in the event that withholding tax is imposed on such payments. In addition, certain of our funding arrangements may require us to pay lenders for increased costs due to certain changes in laws or regulations. Due to the difficulty in predicting events which could cause a breach of the indemnification provisions or trigger a gross-up or other payment obligation, we are not able to estimate our maximum exposure to future payments that could result from claims made under such provisions. We have not made any material payments in the past as a result of these provisions, and as of March 31, 2022, we determined that it is not probable that we will be required to make any material payments in the future. As of March 31, 2022 and 2021, no amounts have been recorded under these indemnification provisions. Litigation and Governmental Proceedings Various legal actions, governmental proceedings and other claims are pending or may be instituted or asserted in the future against us with respect to matters arising in the ordinary course of business. Certain of these actions are or purport to be class action suits, seeking sizeable damages and/or changes in our business operations, policies and practices. Certain of these actions are similar to suits that have been filed against other financial institutions and captive finance companies. In addition, we are subject to governmental and regulatory examinations, information-gathering requests, and investigations from time to time at the state and federal levels. It is inherently difficult to predict the course of such legal actions and governmental inquiries. We perform periodic reviews of pending claims and actions to determine the probability of adverse verdicts and resulting amounts of liability. We establish accruals for legal claims when payments associated with the claims become probable and the costs can be reasonably estimated. When we are able, we also determine estimates of reasonably probable 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. Based on available information and established accruals, we do not believe it is reasonably probable that the results of these proceedings, either individually or in the aggregate, will have a material adverse effect on our consolidated financial condition or results of operations. On November 24, 2020, the Consumer Financial Protection Bureau (“CFPB”) issued a civil investigative demand to the Company seeking, among other things, certain information relating to the Company’s vehicle and payment protection products and credit reporting policies and procedures and reporting records. We are cooperating with the inquiry and cannot predict the eventual scope, duration or outcome at this time. As a result, we are unable to estimate the amount or range of any potential loss arising from this investigation.

General Discussion Of Pension And Other Postretirement Benefits [Abstract]
Pension and Other Benefits	Note 10 – Pension and Other Benefit Plans We are a participating employer in certain retirement and post-retirement medical care, life insurance, and other benefits sponsored by TMNA, an affiliate. Costs of each plan are generally allocated to TMCC based on relative benefit costs associated with participating or eligible employees at TMCC as compared to the plan as a whole. Defined Benefit Plan Prior to January 1, 2015, our employees were generally eligible to participate in the Toyota Motor Sales, U.S.A., Inc. Pension Plan (the “Pension Plan”) the Benefits payable under this non-contributory defined benefit pension plan are based, generally, upon the employees' years of credited service (up to a maximum of 25 years), the highest average annual compensation (as defined in the plan) for any 60 consecutive month period out of the last 120 months of employment (the “Applicable Years”), and one-half of eligible bonus/gift payments for the Applicable Years (recalculated to determine the annual average of such amount), reduced by a percentage of the estimated amount of social security benefits. Costs allocated to TMCC for our employees in the Pension Plan and certain other non-qualified plans were not significant for fiscal 2022, 2021, and 2020. Defined Contribution Plan Employees meeting certain eligibility requirements, as defined in the plan documents, may participate in the Toyota Motor North America, Inc. Retirement TMCC employer contributions to the savings plan were not significant for fiscal 2022, 2021, and 2020. Other Post-Retirement Benefit Plans Employees are generally eligible to participate in other post-retirement benefits sponsored by TMNA which provide certain medical care and life insurance benefits to eligible retired employees. Generally, in order to be eligible for these benefits, the employee must be age 55 or older with 10 or more years of service. Other post-retirement benefit costs allocated to TMCC were not significant for fiscal 2022, 2021, and 2020.

Income Taxes

Income Taxes	Mar. 31, 2022
Income Tax Disclosure [Abstract]
Income Taxes	Note 11 – Income Taxes We use the liability method of accounting for income taxes under which deferred tax assets and liabilities are adjusted to reflect changes in tax rates and laws in the period such changes are enacted resulting in adjustments to the current fiscal year’s provision for income taxes. TMCC files a consolidated federal income tax return with TFSIC and its subsidiaries. Current and deferred federal income taxes are allocated to TMCC as if it were a separate taxpayer. TMCC’s net operating losses and tax credits are utilized when those losses and credits are used by TFSIC and its subsidiaries including TMCC in the consolidated federal income tax return. TMCC files either separate or consolidated/combined state income tax returns with TMNA, TFSIC, or subsidiaries of TMCC. State income tax expense is generally recognized as if TMCC and its subsidiaries filed their tax returns on a stand-alone basis. In those states where TMCC and its subsidiaries join in the filing of consolidated or combined income tax returns, TMCC and its subsidiaries are allocated their share of the total income tax expense based on combined allocation/apportionment factors and separate company income or loss. Based on the federal and state tax sharing agreements, TFSIC and TMCC and its subsidiaries pay for their share of the income tax expense and are reimbursed for the benefit of any of their tax losses and credits utilized in the federal and state income tax returns. The provision for income taxes consisted of the following: Years ended March 31, 2022 2021 2020 Current Federal $ 1,774 $ 2,756 $ (19 ) State 281 386 120 Foreign 22 11 8 Total 2,077 3,153 109 Deferred Federal (1,166 ) (2,243 ) 145 State (123 ) (276 ) (141 ) Foreign 1 (2 ) (2 ) Total (1,288 ) (2,521 ) 2 Provision for income taxes $ 789 $ 632 $ 111 A reconciliation between the U.S. federal statutory tax rate and the effective tax rate is as follows: Years ended March 31, 2022 2021 2020 Provision for income taxes at U.S. federal statutory tax rate 21.0 % 21.0 % 21.0 % State and local taxes (net of federal tax benefit) 3.7 % 3.9 % 4.0 % Effect of state tax law changes 0.3 % (0.2 )% (3.9 )% Federal tax credits 1 (1.0 )% (0.5 )% (3.7 )% Tax rate differential from tax loss carryback - - (5.6 )% Adjustment for prior year provision to return differences (0.3 )% (0.2 )% (1.0 )% Other, net - (0.1 )% - Effective tax rate 23.7 % 23.9 % 10.8 % 1 The amounts in Federal tax credits include tax benefits from foreign tax credits, alternative fuel vehicle credits, plug-in vehicle credits, and research and development credits for fiscal 2022, 2021, and 2020. Note 11 – Income Taxes (Continued) Our net deferred income tax liability consisted of the following deferred tax liabilities and assets: March 31, 2022 2021 Liabilities: Lease transactions $ 1,504 $ 2,765 Voluntary protection dealer commissions 348 290 State taxes, net of federal tax benefit 275 377 Mark-to-market of investments in marketable securities and derivatives 24 34 Other 82 82 Deferred tax liabilities $ 2,233 $ 3,548 Assets: Provision for credit and residual value losses 394 421 Deferred costs and fees 179 187 Accrued expenses 45 21 Lease obligations 23 27 Net operating loss and tax credit carryforwards 14 29 Other 14 12 Deferred tax assets 669 697 Valuation allowance - (9 ) Net deferred tax assets $ 669 $ 688 Net deferred income tax liability 1 $ 1,564 $ 2,860 1 We have no deferred tax assets related to cumulative federal net operating loss carry forwards at March 31, 2022 or March 31, 2021. We have deferred tax assets related to cumulative state net operating loss carry forwards of $13 million and $25 million at March 31, 2022 and March 31, 2021, respectively. State net operating loss carryforwards will expire beginning in fiscal 2024. We have deferred tax assets related to federal tax credit for foreign tax of less than $1 million and $3 million at March 31, 2022 and March 31, 2021, respectively. The federal tax credit carryforwards will expire beginning in fiscal 2032. The deferred tax assets related to foreign tax credit is reduced by a valuation allowance of less than $1 million at March 31, 2022. The deferred tax assets related to foreign tax credit and state tax net operating loss carryforwards were reduced by a valuation allowance of $9 million at March 31, 2021. The determination of the valuation allowance is based on management’s estimate of future taxable income during the respective carryforward periods. Apart from the valuation allowance, we believe that the remaining deferred tax assets will be realized in full. The amount of the deferred tax assets considered realizable could be reduced if management’s estimates change. Note 11 – Income Taxes (Continued) We have made an assertion of permanent reinvestment of earnings from our foreign subsidiary; as a result, other than the deemed repatriation tax that is provided pursuant to the Tax Cuts and Jobs Act of 2017, state and local taxes have not been provided for unremitted earnings of our foreign subsidiary. At March 31, 2022 and 2021, these unremitted earnings totaled $288 million and $251 million, respectively. Determination of the amount of the deferred state and local tax liability is not practicable, and accordingly no estimate of the unrecorded deferred state and local tax liability is provided. Although we do not foresee any events causing repatriation of earnings, possible examples may include but are not limited to parent company capital needs or exiting the business in the foreign country. We had an income tax payable of $52 million and $35 million for our share of the income tax in those states where we filed consolidated or combined returns with TMNA and its subsidiaries at March 31, 2022 and March 31, 2021, respectively. Additionally, our federal and state income tax payable or receivable from TMCC affiliated companies, including TFSIC, TFSB, and Toyota Financial Services Securities USA Corporation, was not significant for both March 31, 2022 and 2021. The guidance for the accounting and reporting for income taxes requires us to assess tax positions in cases where the interpretation of the tax law may be uncertain. The change in unrecognized tax benefits are as follows: March 31, 2022 2021 2020 Balance at beginning of the year $ 15 $ 19 $ 7 Increases related to positions taken during the current year 1 1 12 Increases recorded in current year related to positions taken during prior years 6 2 - Expirations due to lapse of statute - (7 ) - Balance at end of year $ 22 $ 15 $ 19 At March 31, 2022, 2021 and 2020 approximately $22 million, $14 million and $17 million of the respective unrecognized tax benefits would, if recognized, have an effect on the effective tax rate. The remaining amounts in the respective unrecognized tax benefits at March 31, 2022, 2021 and 2020 are related to timing matters. During fiscal 2022, $7 million of the net increase in unrecognized tax benefits had an effect on the effective tax rate. We do not have any positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly increase or decrease within 12 months. We accrue interest, if applicable, related to uncertain income tax positions in interest expense. Statutory penalties, if applicable, accrued with respect to uncertain income tax positions are recognized as an addition to the income tax liability. For each of fiscal 2022, 2021, and 2020, accrued interest was not significant and no penalties were accrued. Tax-related Contingencies As of March 31, 2022, we remained under IRS examination for fiscal 2018 through fiscal 2022.

As of March 31, 2022 and 2021, the subvention receivable from TMNA was $66 million and $184 million, respectively. We have a master netting agreement with TMNA which allows us to net settle payments for shared services and subvention transactions. Under this agreement, as of March 31, 2022 and March 31, 2021, respectively, we had a net amount payable to TMNA which is recorded in Other payables, net in Other liabilities. Our Board of Directors declared and paid cash dividends of $700 million to TFSIC during fiscal 2021. Note 12 – Related Party Transactions (Continued) Financing Support Arrangements with Affiliates TMCC is party to a credit support agreement with TFSC (the “TMCC Credit Support Agreement”). The TMCC Credit Support Agreement requires TFSC to maintain certain ownership, net worth maintenance, and debt service provisions with respect to TMCC, but is not a guarantee by TFSC of any securities or obligations of TMCC. In conjunction with this credit support agreement, TMCC has agreed to pay TFSC a semi-annual fee based on a fixed rate applied to the weighted average outstanding amount of securities entitled to credit support. TCPR is the beneficiary of a credit support agreement with TFSC containing provisions similar to the TMCC Credit Support Agreement described above. In addition, TMCC receives support from and provides financing support to TFSC and other affiliates in the form of promissory notes and various loan and credit facility agreements. As of March 31, 2022 and 2021, total financing support available from affiliates totaled approximately $8.5 billion and $8.6 billion, respectively. These amounts include a $5.0 billion three-year revolving credit facility with TMS which currently expires in fiscal 2025. As of March 31, 2022 and 2021, total financing support available to affiliates totaled approximately $8.0 billion and $7.1 billion, respectively. TMCC’s increased financing support provided to Toyota Finance New Zealand Limited to $250 million in April 2021 and to TFSB to $1.0 billion in August 2021. Additionally, TMCC entered into a financing support agreement with Toyota Finance Corporation (“TFC”) for $100 million in August 2021. The amounts outstanding under these agreements are recorded in Other assets and Other liabilities on our Consolidated Balance Sheets at March 31, 2022 and 2021. In November 2021, in accordance with the financing support agreement, TFC borrowed from TMCC in Japanese Yen a principal amount equivalent to $100 million, to be used for general corporate purposes, with an interest rate of 0.0175% and repayment date of November 2023. The note receivable is translated into U.S. dollars using the applicable exchange rate at the transaction date and retranslated at each balance sheet date using the exchange rate in effect at that date. The resulting transaction gains and losses are included in Investment and Other Income in our Consolidated Statements of Income. In April 2022, TMCC entered into a revolving credit facility with Toyota Financial Services Colombia (“TFSCO”), pursuant to which TFSCO is entitled to borrow a maximum principal amount equivalent to $49 million. Other Financing Support Provided to Affiliates TMCC provides wholesale financing, real estate and working capital loans to certain dealerships that were consolidated with another affiliate under the accounting guidance for variable interest entities. TMCC also pays these dealers origination fees. These costs represent direct costs incurred in connection with the acquisition of retail and lease contracts, including subvention and other cash incentive programs. TMCC has guaranteed the payments of principal and interest with respect to the bonds of manufacturing facilities of certain affiliates. The nature, business purpose, and amounts of these guarantees are described in Note 9 – Commitments and Contingencies. TMCC and TFSB are parties to a master participation agreement pursuant to which TMCC agreed to purchase no more than $60 million per year of residential mortgage loans originated by TFSB that meet specified credit underwriting guidelines.

On all layers in which TMIS has provided coverage, 99 percent of the risk has been ceded to a reinsurer.

Fair Value Measurements

Fair Value Measurements	Mar. 31, 2022
Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 13 – 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. In order to determine fair value of our assets and liabilities, we use quoted prices for identical or similar instruments, otherwise we utilize valuation models with observable or calculated inputs. The use of observable quotes for identical or similar instruments and the use of unobservable inputs is reflected in the fair value hierarchy assessment disclosed in the tables within this Note as Level 1, 2 and 3 defined below. The availability of observable inputs can vary based upon the financial instrument and other factors, such as instrument type, market liquidity and other specific characteristics particular to the financial instrument. To the extent that a valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires additional judgment by management. We use prices and inputs that are current as of the measurement date, including during periods of market disruption. In periods of market disruption, the availability of prices and inputs may be reduced for certain financial instruments. This condition could result in a financial instrument being reclassified from Level 1 to Level 2 or from Level 2 to Level 3. Level 1: Quoted (unadjusted) prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2: Quoted prices in active markets for similar assets and liabilities, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability. Level 3: Unobservable inputs that are supported by little or no market activity and may require significant judgment in order to determine the fair value of the assets and liabilities. Valuation Adjustments We may make valuation adjustments to ensure that financial instruments are recorded at fair value. These adjustments include amounts to reflect counterparty credit quality, our own creditworthiness, as well as constraints due to market illiquidity or unobservable parameters. Recurring Fair Value Measurements Cash and cash equivalents and Restricted cash and cash equivalents The fair value of cash equivalents and restricted cash equivalents approximates the carrying value and these instruments are classified as Level 1 within the fair value hierarchy. Investments in marketable securities We estimate the value of our AFS debt securities, including those for which the fair value option was elected, using observed transaction prices, independent third-party pricing valuation vendors, and internal valuation models. We may hold investments in actively traded open-end and private placement equity investments. Where the equity investments produce a daily net asset value that is quoted in an active market, we use this value to determine the fair value of the equity investment and classify the investment as Level 1 within the fair value hierarchy. The fair value of equity investments that produce a daily net asset value that is not quoted in an active market is estimated using the net asset value per share (or its equivalent) as a practical expedient and are excluded from leveling within the fair value hierarchy. In addition, we may hold individual securities where valuation methodologies and inputs to valuation models depend on the security type, thus they may be classified differently within the leveling hierarchy. Where possible, quoted prices in active markets for identical or similar securities are used to determine the fair value of the investment securities; those securities are classified as Level 1 or 2, respectively. Where quoted prices in active markets are not available, we use various valuation models for each asset class that are consistent with what market participants use. The inputs and assumptions to the models are derived from market observable sources including: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, benchmark securities, bids, offers, and other market-related data. These investments are generally classified as Level 2 within the fair value hierarchy, however, depending on the significance of the unobservable inputs they may also be classified as Level 3. Note 13 – Fair Value Measurements (Continued) Derivatives We estimate the fair value of our derivatives using industry standard valuation models that require observable market inputs, including market prices, interest rates, foreign exchange rates, volatilities, counterparty credit risk, our own non-performance risk and the contractual terms of the derivative instruments. We consider counterparty credit risk and our own non-performance risk through credit valuation adjustments. For derivatives that trade in liquid markets, model inputs can generally be verified and do not require significant management judgment. These derivative instruments are classified as Level 2 within the fair value hierarchy. Certain other derivative transactions trade in less liquid markets with limited pricing information. For such derivatives, key inputs to the valuation process include quotes from counterparties and other market data used to corroborate and adjust values where appropriate. Other market data includes values obtained from a market participant that serves as a third-party valuation vendor. These derivative instruments are classified as Level 3 within the fair value hierarchy. Nonrecurring Fair Value Measurements Nonrecurring fair value measurements include Level 3 net finance receivables that are not measured at fair value on a recurring basis but are subject to fair value adjustments utilizing the fair value of the underlying collateral when there is evidence of impairment. Nonrecurring fair value items as of March 31, 2022 and 2021 were not significant. Retail finance receivables greater than 120 days past due are measured at fair value based on the fair value of the underlying collateral less costs to sell. The fair value of collateral is based on the current average selling prices for like vehicles at wholesale used vehicle auctions. Note 13 – Fair Value Measurements (Continued) Financial assets and financial liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The following tables summarize our financial assets and financial liabilities measured at fair value on a recurring basis by level within the fair value hierarchy except for certain investments that are measured at fair value using the net asset value per share (or its equivalent) as a practical expedient and are excluded from the leveling information provided in the tables below. Fair value amounts presented below are intended to permit reconciliation of the fair value hierarchy to the amounts presented on our Consolidated Balance Sheets.

Note 13 – Fair Value Measurements (Continued) Financial Instruments Not Carried at Fair Value Finance receivables Our finance receivables consist of retail loans and dealer financing loans, which are comprised of wholesale, real estate and working capital financing. Retail finance receivables are primarily valued using a securitization model that incorporates expected cash flows. Cash flows expected to be collected are estimated using contractual principal and interest payments adjusted for specific factors, such as prepayments, extensions, default rates, loss severity, credit scores, and collateral type. The securitization model utilizes quoted secondary market rates if available, or estimated market rates that incorporate management's best estimate of investor assumptions about the portfolio. The dealer financing portfolio is valued using a discounted cash flow model. Discount rates are derived based on market rates for equivalent portfolio bond ratings. As these valuations utilize unobservable inputs, our finance receivables are classified as Level 3 within the fair value hierarchy. Unsecured notes and loans payable The fair value of commercial paper is assumed to approximate the carrying value due to its short duration and generally negligible credit risk. We validate this assumption by recalculating the fair value of our commercial paper using quoted market rates. Commercial paper is classified as Level 2 within the fair value hierarchy. Other unsecured notes and loans payable are primarily valued using current market rates and credit spreads for debt with similar maturities. Our valuation models utilize observable inputs such as standard industry curves; therefore, we classify these unsecured notes and loans payables as Level 2 within the fair value hierarchy. When observable inputs are not available for all assumptions, we estimate the fair value using internal assumptions such as volatility and expected credit losses. As these valuations utilize unobservable inputs, we classify these unsecured notes and loans payable as Level 3 within the fair value hierarchy. Secured notes and loans payable Fair value is estimated based on current market rates and credit spreads for debt with similar maturities. We also use internal assumptions, including prepayment speeds and expected credit losses on the underlying securitized assets, to estimate the timing of cash flows to be paid on these instruments. As these valuations utilize unobservable inputs, our secured notes and loans payables are classified as Level 3 within the fair value hierarchy. Other liabilities Our Other liabilities include notes payable to related parties. As these notes are short term in nature, the carrying value is deemed to approximate fair value and they are classified as Level 3 within the fair value hierarchy. Note 13 – Fair Value Measurements (Continued) Financial Instruments The following tables provide information about assets and liabilities not carried at fair value on a recurring basis on our Consolidated Balance Sheets: March 31, 2022 Carrying Total Fair value Level 1 Level 2 Level 3 value Financial assets Finance receivables Retail loan $ 72,369 $ - $ - $ 73,385 $ 73,385 Wholesale 2,940 - - 2,931 2,931 Real estate 4,985 - - 4,961 4,961 Working capital 2,256 - - 2,171 2,171 Financial liabilities Unsecured notes and loans payable $ 82,288 $ - $ 80,980 $ - $ 80,980 Secured notes and loans payable 26,864 - - 26,500 26,500 March 31, 2021 Carrying Total Fair value Level 1 Level 2 Level 3 value Financial assets Finance receivables Retail loan $ 65,808 $ - $ - $ 69,007 $ 69,007 Wholesale 6,132 - - 6,158 6,158 Real estate 5,142 - - 5,224 5,224 Working capital 2,154 - - 2,171 2,171 Financial liabilities Unsecured notes and loans payable $ 85,513 $ - $ 86,205 $ 555 $ 86,760 Secured notes and loans payable 24,212 - - 24,478 24,478 Accrued interest related to finance receivables is in Other assets on the Consolidated Balance Sheets; however, TMCC measures the fair value of each class of finance receivables using scheduled principal and interest payments. Therefore, accrued interest has been included in the carrying value of each class of finance receivables in the previous tables, along with finance receivables, deferred origination costs, deferred income, and allowance for credit losses. Finance receivables in the previous tables exclude related party transactions, for which the fair value approximates the carrying value, of $90 million and $140 million at March 31, 2022 and 2021, respectively. Fair values of related party finance receivables, net are classified as Level 3 within the fair value hierarchy. For Cash and cash equivalents and Restricted cash and cash equivalents on our Consolidated Balance Sheets, the fair value approximates the carrying value and these instruments are classified as Level 1 within the fair value hierarchy.

Voluntary protection contract revenues We receive the contractually determined dealer cost at the inception of the contract. Revenue is then deferred and recognized over the term of the contract according to earnings factors established by management that are based upon historical loss experience. Contracts sold range in term from 3 to 120 months and are typically cancellable at any time. The effect of subsequent cancellations is recorded as an offset to unearned voluntary protection contract revenues in Other liabilities on our Consolidated Balance Sheets. For the years ended March 31, 2022 and 2021, respectively, approximately 82 percent and 83 percent of voluntary protection contract revenues in the Voluntary protection operations segment were accounted for under the guidance for revenue from contracts with customers. The Voluntary protection operations segment defers contractually determined incentives paid to dealers as contract costs for selling voluntary protection products. These costs are recorded in Other assets on our Consolidated Balance Sheets and are amortized to Operating and administrative expenses in the Consolidated Statements of Income using a methodology consistent with the recognition of revenue. The amount of capitalized dealer incentives and the related amortization was not significant to our consolidated financial statements as of and for the years ended March 31, 2022 and 2021. We had $2.4 billion and $2.5 billion of unearned voluntary protection contract revenues from contracts with customers included in Other liabilities on our Consolidated Balance Sheets as of March 31, 2020 and March 31, 2021, respectively. We recognized $704 million of the unearned amounts in voluntary protection contract revenues in our Consolidated Statements of Income during fiscal 2022, compared to $696 million during fiscal 2021. As of March 31, 2022, we had unearned voluntary protection contract revenues of $2.7 billion included in Other liabilities on our Consolidated Balance Sheet, and with respect to this balance, we expect to recognize revenue of approximately $753 million in fiscal 2023 Insurance earned premiums Revenues from providing coverage under various insurance contracts are recognized over the term of the coverage in relation to the timing and level of anticipated claims. Revenues from insurance policies, net of premiums ceded to reinsurers, are earned over the terms of the respective policies in proportion to the estimated loss development. Management relies on historical loss experience as a basis for establishing earnings factors used to recognize revenue over the term of the contract or policy. Voluntary protection contract expenses and insurance losses Voluntary protection contract expenses and insurance losses include amounts paid and accrued for loss events that are known and have been recorded as claims, estimates of losses incurred but not reported based on actuarial estimates and historical loss development patterns, and loss adjustment expenses that are expected to be incurred in connection with settling and paying these claims. Accruals for unpaid losses, losses incurred but not reported, and loss adjustment expenses are included in Other liabilities on our Consolidated Balance Sheets. These accruals arising from contracts entered into by TMIS are not significant as of March 31, 2022 and 2021. Estimated liabilities are reviewed regularly, and we recognize any adjustments in the periods in which they are determined. If anticipated losses, loss adjustment expenses, and unamortized acquisition and maintenance costs exceed the recorded unearned premium, a premium deficiency is recognized by first charging any unamortized acquisition costs to expense and then by recording a liability for any excess deficiency. Risk Transfer Our voluntary protection operations transfer certain risks to protect us against the impact of unpredictable high severity losses. The amounts recoverable from reinsurers and other companies that assume liabilities relating to our Voluntary protection operations are determined in a manner consistent with the related reinsurance or risk transfer contract. Amounts recoverable from reinsurers and other companies on unpaid losses are recorded as a receivable but are not collectible until the losses are paid. Revenues related to risks transferred are recognized on the same basis as the related revenues from the underlying contracts. Covered losses are recorded as a reduction to Voluntary protection contract expenses and insurance losses.

Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation Our accounting and financial reporting policies conform to accounting principles generally accepted in the United States of America (“U.S. GAAP”). Related party transactions presented in the Consolidated Financial Statements are disclosed in Note 12 – Related Party Transactions. The consolidated financial statements include the accounts of TMCC, its wholly-owned subsidiaries and all variable interest entities (“VIE”) of which we are the primary beneficiary. All intercompany transactions and balances have been eliminated.
Use of Estimates	Use of Estimates 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 the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Because of inherent uncertainty involved in making estimates, actual results could differ from those estimates and assumptions. The accounting estimates that are most important to our business are the accumulated depreciation related to our investments in operating leases and the allowance for credit losses.
Recently Adopted Accounting Guidance	Recently Adopted Accounting Guidance In fiscal 2021, we adopted Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments Refer to Note 2 – Investments in Marketable Securities, Note 3 – Finance Receivables, Net, and Note 4 – Allowance for Credit Losses for additional information. In conjunction with the adoption of ASU 2016-13, we updated our depreciation policy for operating leases so that the useful life of the vehicles incorporates our historical experience on early terminations due to customer defaults. As a result, we changed the presentation for reporting early termination expenses related to customer defaults on investments in operating leases. We now present the effects of operating lease early terminations as part of accumulated depreciation within Investments in operating leases, net in the Consolidated Balance Sheets and Depreciation on operating leases in the Consolidated Statements of Income. The comparative period’s information continues to be reported under the relevant accounting presentation in effect for that period. Refer to Note 5 – Investments in Operating Leases, Net for additional information. Note 1 – Basis of Presentation and Significant Accounting Policies (Continued) On April 1, 2021, we adopted the following new accounting standards: We adopted Accounting Standards Update (“ASU”) 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, We adopted ASU 2020-08, Codification Improvements to Subtopic 310-20, Receivables-Nonrefundable Fees and Other Costs
Accounting Guidance Issued But Not Yet Adopted	Accounting Guidance Issued But Not Yet Adopted In July 2021, the FASB issued ASU 2021-05, Lessors-Certain Leases with Variable Lease Payments (Topic 842) In March 2022, the FASB issued ASU 2022-02, Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures Financial Instruments – Credit Losses (Topic 326 Measurement of Credit Losses on Financial Instruments
Cash and Cash Equivalents	Cash and cash equivalents Cash and cash equivalents represent highly liquid investments with maturities of three months or less from the date of acquisition and may include money market instruments, commercial paper, certificates of deposit, U.S. government and agency obligations, or similar instruments.
Restricted Cash and Cash Equivalents	Restricted cash and cash equivalents Restricted cash and cash equivalents include customer collections on securitized receivables to be distributed to investors as payments on the related secured notes and loans payable, which are primarily related to securitization trusts. Restricted cash equivalents may also contain proceeds from certain debt issuances for which the use of the cash is restricted.
Investments in Marketable Securities	Investments in marketable securities Investments in marketable securities consist of debt securities and equity investments. We classify all of our debt securities as available-for-sale (“AFS”). Except when the fair value option is elected, AFS debt securities are recorded at fair value with unrealized gains or losses included in accumulated other comprehensive income (“AOCI”), net of applicable taxes. Realized gains and losses from sales of AFS debt securities are determined using the specific identification method or first in first out method and are included in Investment and other income, net in our Consolidated Statements of Income. In fiscal 2021, we adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments In fiscal 2022, we have elected the fair value option for certain debt securities held within one of our affiliate investment portfolios for operational ease given the size and composition of this portfolio. All debt securities within this specific portfolio are recorded at fair value with changes in fair value included in Investment and other income, net in our Consolidated Statements of Income. AFS debt securities for which the fair value option is elected are not subject to credit loss impairment. As of March 31, 2022, we held AFS debt securities for which the fair value option was elected of $674 million. The difference between the aggregate fair value and the aggregate unpaid principal balance of long-term AFS debt securities for which the fair value option was elected was not significant. All equity investments are recorded at fair value with changes in fair value included in Investment and other income, net in our Consolidated Statements of Income. Realized gains and losses from sales of equity investments are determined using the first in first out method and are included in Investment and other income, net in our Consolidated Statements of Income.
Finance Receivables, Net	Finance receivables, net consists of retail loan and dealer products portfolio segments, and includes deferred origination costs, deferred income, and allowance for credit losses. Finance receivables, net also includes securitized retail receivables, which represent retail receivables that have been sold for legal purposes to securitization trusts but continue to be included in our consolidated financial statements, as discussed further in Note 8 – Variable Interest Entities. Cash flows from these securitized retail receivables are available only for the repayment of debt issued by these trusts and other obligations arising from the securitization transactions. They are not available for payment of our other obligations or to satisfy claims of our other creditors. Finance receivables are classified as held-for-investment if the Company has the intent and ability to hold the receivables for the foreseeable future or until maturity or payoff. As of March 31, 2022 and 2021, all finance receivables were classified as held-for-investment. Revenues associated with retail and dealer financing are recognized to approximate a constant effective yield over the contract term. Incremental direct fees and costs incurred in connection with the acquisition of retail contracts and dealer financing receivables, including incentive and rate participation payments made to dealers, are capitalized and amortized to approximate a constant effective yield over the term of the related contracts. Payments received on subvention and other consumer incentives are deferred and recognized to approximate a constant effective yield over the term of the related contracts. Accrued interest related to finance receivables are presented within Other assets on the Consolidated Balance Sheet and was $214 million and $187 million at March 31, 2022 and 2021, respectively. For both retail loan and dealer products portfolio segments, accrued interest, deferred income, and deferred origination costs, if any, are written off within Provision for credit losses at the earlier of when an account is deemed to be uncollectible or when an account is greater than 120 days past due. Credit Quality Indicators We are exposed to credit risk on our finance receivables. Credit risk is the risk of loss arising from the failure of customers or dealers to meet the terms of their contracts with us or otherwise fail to perform as agreed. Retail Loan Portfolio Segment The retail loan portfolio segment consists of one class of finance receivables. While we use various credit quality metrics to develop our allowance for credit losses on the retail loan portfolio segment, we primarily utilize the aging of the individual accounts to monitor the credit quality of these finance receivables. Based on our experience, the payment status of borrowers is the strongest indicator of the credit quality of the underlying receivables. Payment status also impacts charge-offs. Individual borrower accounts within the retail loan portfolio segment are segregated into aging categories based on the number of days past due. The aging of finance receivables is updated monthly. Dealer Products Portfolio Segment The dealer products portfolio segment consists of three classes of finance receivables: wholesale, real estate and working capital. All loans outstanding for an individual dealer or dealer group, which includes affiliated entities, are aggregated and evaluated collectively by dealer or dealer group. This reflects the interconnected nature of financing provided to our individual dealer and dealer group customers, and their affiliated entities. When assessing the credit quality of the finance receivables within the dealer products portfolio segment, we segregate the finance receivables account balances into four categories representing distinct credit quality indicators based on internal risk assessments. The internal risk assessments for all finance receivables within the dealer products portfolio segment are updated on a monthly basis. The four credit quality indicators are: • Performing – Account not classified as either Credit Watch, At Risk or Default; • Credit Watch – Account designated for elevated attention; • At Risk – Account where there is an increased likelihood that default may exist based on qualitative and quantitative factors; and • Default – Account is not currently meeting contractual obligations or we have temporarily waived certain contractual requirements Past Due Finance Receivables by Class Substantially all finance receivables do not involve recourse to the dealer in the event of customer default. Finance receivables include contracts greater than 120 days past due, which are recorded at the fair value of collateral less estimated costs to sell, and contracts in bankruptcy. Contracts for which vehicles have been repossessed are excluded. For all finance receivables, we define “past due” as any payment, including principal and interest, that is at least 30 days past the contractual due date. For any customer who is granted a payment extension under an extension program, the aging of the receivable is adjusted for the number of days of the extension granted. Troubled Debt Restructuring A troubled debt restructuring occurs when a finance receivable is modified through a concession to a borrower experiencing financial difficulty. A finance receivable modified under a troubled debt restructuring is considered to be impaired. In addition, troubled debt restructurings include finance receivables for which the customer has filed for bankruptcy protection. For such finance receivables, we no longer have the ability to modify the terms of the agreement without the approval of the bankruptcy court and the court may impose term modifications that we are obligated to accept. For accounts not under bankruptcy protection, the amount of finance receivables modified as a troubled debt restructuring during fiscal 2022 and 2021 was not significant for each class of finance receivables. Troubled debt restructurings for accounts not under bankruptcy protection within the retail loan class of finance receivables are comprised exclusively of contract term extensions that reduce the monthly payment due from the customer. For the three classes of finance receivables within the dealer products portfolio segment, troubled debt restructurings include contract term extensions, interest rate adjustments, waivers of loan covenants, or any combination of the three. Troubled debt restructurings of accounts not under bankruptcy protection did not include forgiveness of principal or interest rate adjustments during fiscal 2022 and 2021. We consider finance receivables under bankruptcy protection within the retail loan class to be troubled debt restructurings as of the date we receive notice of a customer filing for bankruptcy protection, regardless of the ultimate outcome of the bankruptcy proceedings. The bankruptcy court may impose modifications as part of the proceedings, including interest rate adjustments and forgiveness of principal. For fiscal 2022 and 2021, the financial impact of troubled debt restructurings related to finance receivables under bankruptcy protection was not significant to our Consolidated Statements of Income and Consolidated Balance Sheets.
Allowance for Credit Losses	Upon adoption of ASU 2016-13 in fiscal 2021, the incurred loss impairment method was replaced with a new impairment model that reflects lifetime expected losses. Management develops and documents the allowance for credit losses on finance receivables based on two portfolio segments. The determination of portfolio segments is based primarily on the qualitative consideration of the nature of our business operations and the characteristics of the underlying finance receivables, as follows: • Retail Loan Portfolio Segment – The retail loan portfolio segment consists of retail contracts acquired from dealers in the U.S. and Puerto Rico. Under a retail contract, we are granted a security interest in the underlying collateral which consists primarily of Toyota, Lexus, and private label vehicles. Based on the common risk characteristics associated with the finance receivables, the retail loan portfolio segment is considered a single class of finance receivable. • Dealer Products Portfolio Segment – The dealer products portfolio segment consists of wholesale financing, working capital loans, revolving lines of credit and real estate loans to dealers in the U.S. and Puerto Rico. Wholesale financing is primarily collateralized by new or used vehicle inventory with the outstanding balance fluctuating based on the level of inventory. Working capital loans and revolving lines of credit are granted for working capital purposes and are secured by dealership assets. Real estate loans are collateralized by the underlying real estate, are underwritten primarily on a loan-to-value basis and are typically for a fixed term. Based on the risk characteristics associated with the underlying finance receivables, the dealer products portfolio segment consists of three classes of finance receivables: wholesale, working capital (including revolving lines of credit), and real estate. Management’s estimate of lifetime expected credit losses is based on an evaluation of relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the future collectability of the finance receivables. Management’s evaluation takes into consideration the risks in the retail loan portfolio and dealer products portfolio, past loss experience, delinquency trends, underwriting and collection practices, changes in portfolio composition, economic forecasts and other relevant factors. Methodology Used to Develop the Allowance for Credit Losses The allowance for credit losses is measured on a collective basis when loans have similar risk characteristics. Loans that do not share similar risk characteristics are evaluated on an individual basis. We generally use a discounted cash flow approach for determining allowance for credit losses for finance receivables modified as a troubled debt restructuring that are granted with interest rate concessions, and a non-discounted cash flow approach for other loans. We measure expected losses of all components of finance receivables on an amortized cost basis, excluding accrued interest, and including off-balance-sheet lending commitments that are not unconditionally cancellable by TMCC. Estimated expected credit losses for off-balance-sheet lending commitments within our dealer products portfolio are included in Other liabilities on the Consolidated Balance Sheets. We have elected to exclude accrued interest from the measurement of expected credit losses as we apply policies and procedures that result in the timely write-offs of accrued interest. Accrued interest is written off within allowance for credit losses at the earlier of when an account is deemed to be uncollectible or when an account is greater than 120 days past due. Retail Loan Portfolio Segment The level of credit risk in our retail loan portfolio segment is influenced by various factors such as economic conditions, the used vehicle market, credit quality, contract structure, and collection strategies and practices. The allowance for credit losses is measured on a collective basis when loans have similar risk characteristics such as loan-to-value ratio, book payment-to-income ratio, FICO score at origination, collateral type, contract term, and other relevant factors. We use statistical models to estimate lifetime expected credit losses of our retail loan portfolio segment by applying probability of default and loss given default to the exposure at default on a loan level basis. Probability of default models are developed from internal risk scoring models which consider variables such as delinquency status, historical default frequency, and other credit quality indicators such as loan-to-value ratio, book payment-to-income ratio, FICO score at origination, collateral type (new or used, Lexus, Toyota, or private label), and contract term. Note 4 – Allowance for Credit Losses (Continued) Loss given default models forecast the extent of losses given that a default has occurred and considers variables such as collateral, trends in recoveries, historical loss severity, and other contract structure variables. Exposure at default represents the expected outstanding principal balance, including the effects of expected prepayment when applicable. The lifetime expected credit losses incorporate the probability-weighted forward-looking macroeconomic forecasts for baseline, favorable, and adverse scenarios. The loan lifetime is regarded by management as the reasonable and supportable period. We use macroeconomic forecasts from a third party and update such forecasts quarterly. On an ongoing basis, we review our models, including macroeconomic factors, the selection of macroeconomic scenarios and their weighting to ensure they reflect the risk of the portfolio. If management does not believe the models reflect lifetime expected credit losses, a qualitative adjustment is made to reflect management judgment regarding observable changes in recent or expected economic trends and conditions, portfolio composition, and other relevant factors. While management uses the best information available to make such evaluations, future adjustments to the allowance for credit losses may be necessary if conditions differ substantially from the assumptions used in making the evaluations. Dealer Products Portfolio Segment The level of credit risk in our dealer products portfolio segment is influenced primarily by the financial strength of dealers within our portfolio, dealer concentration, collateral quality, and other economic factors. The financial strength of dealers within our portfolio is influenced by, among other factors, general economic conditions, the overall demand for new and used vehicles and the financial condition of automotive manufacturers. The allowance for credit losses is established for both outstanding dealer finance receivables and certain unfunded off-balance sheet lending commitments. The allowance for credit losses is measured on a collective basis when loans have similar risk characteristics such as dealer group internal risk rating and loan-to-value ratios. We measure lifetime expected credit losses of our dealer products portfolio segment by applying probability of default and loss given default to the exposure at default on a loan level basis. Probability of default is primarily established based on internal risk assessments. The probability of default model also considers qualitative factors related to macroeconomic outlooks. Loss given default is established based on the nature and market value of the collateral, loan-to-value ratios and other credit quality indicators. Exposure at default represents the expected outstanding principal balance. The lifetime of the loan or lending commitment is regarded by management as the reasonable and supportable period. On an ongoing basis, we review our models, including macroeconomic outlooks, to ensure they reflect the risk of the portfolio. If management does not believe the models reflect lifetime expected credit losses, a qualitative adjustment is made to reflect management judgment regarding observable changes in recent or expected economic trends and conditions, portfolio composition, and other relevant factors. While management uses the best information available to make such evaluations, future adjustments to the allowance for credit losses may be necessary if conditions differ substantially from the assumptions used in making the evaluations. Accounting for the Allowance for Credit Losses Increases to the allowance for credit losses are accompanied by corresponding charges to the Provision for credit losses in our Consolidated Statements of Income. The uncollectible portion of finance receivables is charged to the allowance for credit losses at the earlier of when an account is deemed to be uncollectible or when an account is greater than 120 days past due. In the event we repossess the collateral, the receivable is charged-off and we record the collateral at its estimated fair value less costs to sell and report it in Other assets on our Consolidated Balance Sheets. Recoveries of finance receivables previously charged off as uncollectible are credited to the allowance for credit losses.
Investments in Operating Leases, Net	Investments in operating leases, net consists of vehicle lease contracts acquired from dealers, and includes deferred origination fees and costs, deferred income, and accumulated depreciation. Generally, lessees have the ability to extend their lease term in six month increments up to a total of 12 months from the original lease maturity date. A lease can be terminated at any time by satisfying the obligations under the lease contract. Early termination programs may be occasionally offered to eligible lessees. At the end of the lease, the customer has the option to buy the leased vehicle or return the vehicle to the dealer. Securitized investments in operating leases represent beneficial interests in a pool of certain vehicle leases that have been sold for legal purposes to securitization trusts but continue to be included in our consolidated financial statements as discussed further in Note 8 - Variable Interest Entities. Cash flows from these securitized investments in operating leases are available only for the repayment of debt issued by these trusts and other obligations arising from the securitization transactions. They are not available for payment of our other obligations or to satisfy claims of our other creditors. Operating lease revenues are recognized on a straight-line basis over the term of the lease. We have made an accounting policy election to exclude from the consideration in the contract, and from variable payments not included in the consideration in the contract, sales and other taxes assessed by a governmental authority that are both imposed on and concurrent with a specific lease revenue-producing transaction and collected from customers. Deferred fees and costs include incentive payments made to dealers and acquisition fees collected from customers. Deferred income includes payments received on affiliate sponsored subvention and other incentive programs. Both deferred fees and costs and deferred income are capitalized or deferred and amortized on a straight-line basis over the contract term. The accrual of revenue on investments in operating leases is discontinued at the time an account is determined to be uncollectible and subsequent revenue is recognized only to the extent a payment is received. Operating leases may be restored to accrual status when future payments are reasonably assured. Vehicle Lease Residual Values Contractual residual values of vehicle lease contracts are estimated at lease inception by examining external industry data, the anticipated Toyota, Lexus, and private label product pipeline and our own experience. Factors considered in this evaluation include macroeconomic forecasts, new vehicle pricing, new vehicle incentive programs, new vehicle sales, vehicle features and specifications, the mix and level of used vehicle supply, the level of current used vehicle values, and fuel prices. We are exposed to a risk of loss to the extent the customer returns the vehicle and the value of the vehicle is lower than the residual value estimated at inception of the lease or if the number of returned vehicles is higher than anticipated. Depreciation on operating leases is recognized using the straight-line method over the lease term. The depreciable basis is the original acquisition cost of the vehicle less the estimated residual value of the vehicle at the end of the lease term. On a quarterly basis, we review the estimated end-of-term market values and return rates of leased vehicles to assess the appropriateness of the carrying values at lease-end. Factors affecting the estimated end-of-term market value are similar to those considered in the evaluation of residual values at lease inception discussed above. Adjustments to depreciation expense to reflect revised estimates of expected market values at lease termination and revised return rates are recorded prospectively on a straight-line basis over the remaining lease term. We use various channels to sell vehicles returned at lease-end. Upon disposition, the difference between the net book value of the lease and the proceeds received from the disposition of the asset, including any insurance proceeds is recorded as an adjustment to depreciation on operating leases. Note 5 – Investments in Operating Leases, Net (Continued) Our depreciation policy for operating leases incorporates our historical experience on early terminations due to customer defaults into the useful live of the vehicles. We consider the effects of operating lease early terminations when determining depreciation estimates, which are included as part of accumulated depreciation within Investments in operating leases, net on the Consolidated Balance Sheets and Depreciation on operating leases in the Consolidated Statements of Income.
Derivative Instruments	Derivative Instruments Our liabilities consist mainly of fixed and variable rate debt, denominated in U.S. dollars and various other currencies, which we issue in the global capital markets, while our assets consist primarily of U.S. dollar denominated, fixed rate receivables. We enter into interest rate swaps and foreign currency swaps to economically hedge the interest rate and foreign currency risks that result from the different characteristics of our assets and liabilities. Our use of derivative transactions is intended to reduce long-term fluctuations in the fair value of assets and liabilities caused by market movements. All of our derivatives are categorized as not designated for hedge accounting, and all of our derivative activities are authorized and monitored by our management and our Asset-Liability Committee which provides a framework for financial controls and governance to manage market risk. All derivative instruments are recorded on the balance sheet at fair value, taking into consideration the effects of legally enforceable master netting agreements that allow us to net settle asset and liability positions and offset cash collateral with the same counterparty on a net basis. Changes in the fair value of our derivative instruments are recorded in Interest expense in our Consolidated Statements of Income. The derivative instruments are included as a component of Other assets or Other liabilities on our Consolidated Balance Sheets.
Offsetting of Derivatives	Offsetting of Derivatives Accounting guidance permits the net presentation on our Consolidated Balance Sheets of derivative receivables and derivative payables with the same counterparty and the related cash collateral when a legally enforceable master netting agreement exists, or when the derivative receivables and derivative payables meet all the conditions for the right of setoff to exist. When we meet this condition, we elect to present such balances on a net basis. Over-the-Counter (“OTC”) Derivatives Our International Swaps and Derivatives Association Master Agreements are our master netting agreements which permit multiple transactions to be cancelled and settled with a single net balance paid to either party for our OTC derivatives. The master netting agreements also contain reciprocal collateral agreements which require the transfer of cash collateral to the party in a net asset position across all transactions. Our collateral agreements with substantially all our counterparties include a zero threshold, full collateralization arrangement. Although we have daily valuation and collateral exchange arrangements with all of our counterparties, due to the time required to move collateral, there may be a delay of up to one day between the exchange of collateral and the valuation of our derivatives. We would not be required to post additional collateral to the counterparties with whom we were in a net liability position at March 31, 2022, if our credit ratings were to decline, since we fully collateralize without regard to credit ratings with these counterparties. In addition, as our collateral agreements include legal right of offset provisions, collateral amounts are netted against derivative assets or derivative liabilities, and the net amount is included in Other assets or Other liabilities on our Consolidated Balance Sheets. Centrally Cleared Derivatives For our centrally cleared derivatives, variation margin payments are legally characterized as settlement payments and accounted for with corresponding derivative positions as one unit of account as opposed to collateral. Initial margin payments are separately recorded in Other assets on our Consolidated Balance Sheets. We perform valuation and margin exchange on a daily basis. Similar to the OTC swaps, there may be a delay of up to one day between the exchange of margin payments and the valuation of our derivatives.
Debt Issuance Costs	Debt issuance costs are deferred and amortized to interest expense on an effective yield basis over the contractual term of the debt.
Foreign Currency Transactions	Upon issuance of fixed rate debt, we generally elect to enter into pay-float swaps to convert fixed rate payments on debt to floating rate payments. Certain unsecured notes and loans payable are denominated in various foreign currencies. The debt is translated into U.S. dollars using the applicable exchange rate at the transaction date and retranslated at each balance sheet date using the exchange rate in effect at that date. The resulting transaction gains and losses are included in Interest expense in our Consolidated Statements of Income. Concurrent with the issuance of these foreign currency unsecured notes and loans payable, we enter into currency swaps in the same notional amount to convert non-U.S. currency payments to U.S. dollar denominated payments. Gains and losses related to foreign currency transactions are included in Interest expense in our Consolidated Statements of Income.
Secured Notes and Loans Payable	Secured Notes and Loans Payable Our secured notes and loans payable are denominated in U.S. dollars and consist of both fixed and variable rate debt. Secured notes and loans payable are issued using on-balance sheet securitization trusts, as further discussed in Note 8 – Variable Interest Entities. These notes are repayable only from collections on the underlying securitized retail finance receivables and the beneficial interests in investments in operating leases and from related credit enhancements. Some of our secured notes are backed by a revolving pool of finance receivables and cash collateral, with the ability to repay the notes in full after the revolving period ends, after which an amortization period begins.
Variable Interest Entities	A VIE is an entity that either (i) has insufficient equity to permit the entity to finance its activities without additional subordinated financial support or (ii) has equity investors who lack the characteristics of a controlling financial interest. The primary beneficiary of a VIE is the party with both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and the obligation to absorb the losses or the right to receive benefits that could potentially be significant to the VIE. To assess whether we have the power to direct the activities of a VIE that most significantly impact its economic performance, we consider all the facts and circumstances including our role in establishing the VIE and our ongoing rights and responsibilities. This assessment includes identifying the activities that most significantly impact the VIE’s economic performance and identifying which party, if any, has power over those activities. In general, the party that makes the most significant decisions affecting the VIE is determined to have the power to direct the activities of the VIE. To assess whether we have the obligation to absorb the losses or the right to receive benefits that could potentially be significant to the VIE, we consider all of our economic interests, including debt and equity interests, servicing rights and fee arrangements, and any other variable interests in the VIE. If we determine that we are the party with the power to make the most significant decisions affecting the VIE, and we have an obligation to absorb the losses or the right to receive benefits that could potentially be significant to the VIE, then we consolidate the VIE. We perform ongoing reassessments, usually quarterly, of whether we are the primary beneficiary of a VIE. The reassessment process considers whether we have acquired or divested the power to direct the most significant activities of the VIE through changes in governing documents or other circumstances. We also reconsider whether entities previously determined not to be VIEs have become VIEs, based on new events, and therefore could be subject to the VIE consolidation framework. We use one or more special purpose entities that are considered VIEs to issue asset-backed securities to third-party bank-sponsored asset-backed securitization vehicles and to investors in securitization transactions. The securities issued by these VIEs are backed by the cash flows related to retail finance receivables and beneficial interests in investments in operating leases (“Securitized Assets”). We hold variable interests in the VIEs that could potentially be significant to the VIEs. We determined that we are the primary beneficiary of the securitization trusts because (i) our servicing responsibilities for the Securitized Assets give us the power to direct the activities that most significantly impact the performance of the VIEs, and (ii) our variable interests in the VIEs give us the obligation to absorb losses and the right to receive residual returns that could potentially be significant. Restricted cash, including cash equivalents, shown in the previous tables represent collections from the underlying Net securitized assets and certain reserve deposits held by TMCC for the VIEs and is included as part of Restricted cash and cash equivalents on our Consolidated Balance Sheets. Net securitized assets shown in the previous tables are presented net of deferred fees and costs, deferred income, accumulated depreciation, and allowance for credit losses. Other assets represent accrued interests related to securitized retail finance receivables and used vehicles held-for-sale that were repossessed by or returned to TMCC for the benefit of the VIEs. The related debt of these consolidated VIEs is presented net of $1,667 million and $1,409 million of securities retained by TMCC at March 31, 2022 and 2021, respectively. Other liabilities represent accrued interest on the debt of the consolidated VIEs. The assets of the VIEs and the Restricted cash and cash equivalents held by TMCC serve as the sole source of repayment for the asset-backed securities issued by these entities. Investors in the notes issued by the VIEs do not have recourse to us or our other assets, with the exception of customary representation and warranty repurchase provisions and indemnities. As the primary beneficiary of these entities, we are exposed to credit, residual value, interest rate, and prepayment risk from the Securitized Assets in the VIEs. However, our exposure to these risks did not change as a result of the transfer of the assets to the VIEs. We may also be exposed to interest rate risk arising from the secured notes issued by the VIEs. In addition, we entered into interest rate swaps with certain special purpose entities that issue variable rate debt. Under the terms of these swaps, the special purpose entities are obligated to pay TMCC a fixed rate of interest on certain payment dates in exchange for receiving a floating rate of interest on notional amounts equal to the outstanding balance of the secured debt. This arrangement enables the special purpose entities to mitigate the interest rate risk inherent in issuing variable rate debt that is secured by fixed rate Securitized Assets. The transfers of the Securitized Assets to the special purpose entities in our securitizations are considered to be sales for legal purposes. However, the Securitized Assets and the related debt remain on our Consolidated Balance Sheets. We recognize financing revenue on the Securitized Assets and interest expense on the secured debt issued by the special purpose entities. We also maintain an allowance for credit losses on the securitized retail finance receivables using a methodology consistent with that used for our non-securitized asset portfolio. The interest rate swaps between TMCC and the special purpose entities are considered intercompany transactions and therefore are eliminated in our consolidated financial statements.
Income Taxes	We use the liability method of accounting for income taxes under which deferred tax assets and liabilities are adjusted to reflect changes in tax rates and laws in the period such changes are enacted resulting in adjustments to the current fiscal year’s provision for income taxes. TMCC files a consolidated federal income tax return with TFSIC and its subsidiaries. Current and deferred federal income taxes are allocated to TMCC as if it were a separate taxpayer. TMCC’s net operating losses and tax credits are utilized when those losses and credits are used by TFSIC and its subsidiaries including TMCC in the consolidated federal income tax return. TMCC files either separate or consolidated/combined state income tax returns with TMNA, TFSIC, or subsidiaries of TMCC. State income tax expense is generally recognized as if TMCC and its subsidiaries filed their tax returns on a stand-alone basis. In those states where TMCC and its subsidiaries join in the filing of consolidated or combined income tax returns, TMCC and its subsidiaries are allocated their share of the total income tax expense based on combined allocation/apportionment factors and separate company income or loss. Based on the federal and state tax sharing agreements, TFSIC and TMCC and its subsidiaries pay for their share of the income tax expense and are reimbursed for the benefit of any of their tax losses and credits utilized in the federal and state income tax returns.
Fair Value Measurement	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. In order to determine fair value of our assets and liabilities, we use quoted prices for identical or similar instruments, otherwise we utilize valuation models with observable or calculated inputs. The use of observable quotes for identical or similar instruments and the use of unobservable inputs is reflected in the fair value hierarchy assessment disclosed in the tables within this Note as Level 1, 2 and 3 defined below. The availability of observable inputs can vary based upon the financial instrument and other factors, such as instrument type, market liquidity and other specific characteristics particular to the financial instrument. To the extent that a valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires additional judgment by management. We use prices and inputs that are current as of the measurement date, including during periods of market disruption. In periods of market disruption, the availability of prices and inputs may be reduced for certain financial instruments. This condition could result in a financial instrument being reclassified from Level 1 to Level 2 or from Level 2 to Level 3. Level 1: Quoted (unadjusted) prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2: Quoted prices in active markets for similar assets and liabilities, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability. Level 3: Unobservable inputs that are supported by little or no market activity and may require significant judgment in order to determine the fair value of the assets and liabilities. Valuation Adjustments We may make valuation adjustments to ensure that financial instruments are recorded at fair value. These adjustments include amounts to reflect counterparty credit quality, our own creditworthiness, as well as constraints due to market illiquidity or unobservable parameters. Recurring Fair Value Measurements Cash and cash equivalents and Restricted cash and cash equivalents The fair value of cash equivalents and restricted cash equivalents approximates the carrying value and these instruments are classified as Level 1 within the fair value hierarchy. Investments in marketable securities We estimate the value of our AFS debt securities, including those for which the fair value option was elected, using observed transaction prices, independent third-party pricing valuation vendors, and internal valuation models. We may hold investments in actively traded open-end and private placement equity investments. Where the equity investments produce a daily net asset value that is quoted in an active market, we use this value to determine the fair value of the equity investment and classify the investment as Level 1 within the fair value hierarchy. The fair value of equity investments that produce a daily net asset value that is not quoted in an active market is estimated using the net asset value per share (or its equivalent) as a practical expedient and are excluded from leveling within the fair value hierarchy. In addition, we may hold individual securities where valuation methodologies and inputs to valuation models depend on the security type, thus they may be classified differently within the leveling hierarchy. Where possible, quoted prices in active markets for identical or similar securities are used to determine the fair value of the investment securities; those securities are classified as Level 1 or 2, respectively. Where quoted prices in active markets are not available, we use various valuation models for each asset class that are consistent with what market participants use. The inputs and assumptions to the models are derived from market observable sources including: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, benchmark securities, bids, offers, and other market-related data. These investments are generally classified as Level 2 within the fair value hierarchy, however, depending on the significance of the unobservable inputs they may also be classified as Level 3. Derivatives We estimate the fair value of our derivatives using industry standard valuation models that require observable market inputs, including market prices, interest rates, foreign exchange rates, volatilities, counterparty credit risk, our own non-performance risk and the contractual terms of the derivative instruments. We consider counterparty credit risk and our own non-performance risk through credit valuation adjustments. For derivatives that trade in liquid markets, model inputs can generally be verified and do not require significant management judgment. These derivative instruments are classified as Level 2 within the fair value hierarchy. Certain other derivative transactions trade in less liquid markets with limited pricing information. For such derivatives, key inputs to the valuation process include quotes from counterparties and other market data used to corroborate and adjust values where appropriate. Other market data includes values obtained from a market participant that serves as a third-party valuation vendor. These derivative instruments are classified as Level 3 within the fair value hierarchy. Nonrecurring Fair Value Measurements Nonrecurring fair value measurements include Level 3 net finance receivables that are not measured at fair value on a recurring basis but are subject to fair value adjustments utilizing the fair value of the underlying collateral when there is evidence of impairment. Nonrecurring fair value items as of March 31, 2022 and 2021 were not significant. Retail finance receivables greater than 120 days past due are measured at fair value based on the fair value of the underlying collateral less costs to sell. The fair value of collateral is based on the current average selling prices for like vehicles at wholesale used vehicle auctions. Note 13 – Fair Value Measurements (Continued) Financial assets and financial liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The following tables summarize our financial assets and financial liabilities measured at fair value on a recurring basis by level within the fair value hierarchy except for certain investments that are measured at fair value using the net asset value per share (or its equivalent) as a practical expedient and are excluded from the leveling information provided in the tables below. Fair value amounts presented below are intended to permit reconciliation of the fair value hierarchy to the amounts presented on our Consolidated Balance Sheets.
Fair Value Transfer	Level 3 Fair Value Measurements The Level 3 financial assets and liabilities recorded at fair value which are subject to recurring and nonrecurring fair value measurement, and the corresponding activity and change in the fair value measurements of these assets and liabilities, were not significant to our Consolidated Balance Sheets as of March 31, 2022 and 2021, or Consolidated Statements of Income for the years ended March 31, 2022 and 2021.
Financial Instruments Not Carried at Fair Value	Financial Instruments Not Carried at Fair Value Finance receivables Our finance receivables consist of retail loans and dealer financing loans, which are comprised of wholesale, real estate and working capital financing. Retail finance receivables are primarily valued using a securitization model that incorporates expected cash flows. Cash flows expected to be collected are estimated using contractual principal and interest payments adjusted for specific factors, such as prepayments, extensions, default rates, loss severity, credit scores, and collateral type. The securitization model utilizes quoted secondary market rates if available, or estimated market rates that incorporate management's best estimate of investor assumptions about the portfolio. The dealer financing portfolio is valued using a discounted cash flow model. Discount rates are derived based on market rates for equivalent portfolio bond ratings. As these valuations utilize unobservable inputs, our finance receivables are classified as Level 3 within the fair value hierarchy. Unsecured notes and loans payable The fair value of commercial paper is assumed to approximate the carrying value due to its short duration and generally negligible credit risk. We validate this assumption by recalculating the fair value of our commercial paper using quoted market rates. Commercial paper is classified as Level 2 within the fair value hierarchy. Other unsecured notes and loans payable are primarily valued using current market rates and credit spreads for debt with similar maturities. Our valuation models utilize observable inputs such as standard industry curves; therefore, we classify these unsecured notes and loans payables as Level 2 within the fair value hierarchy. When observable inputs are not available for all assumptions, we estimate the fair value using internal assumptions such as volatility and expected credit losses. As these valuations utilize unobservable inputs, we classify these unsecured notes and loans payable as Level 3 within the fair value hierarchy. Secured notes and loans payable Fair value is estimated based on current market rates and credit spreads for debt with similar maturities. We also use internal assumptions, including prepayment speeds and expected credit losses on the underlying securitized assets, to estimate the timing of cash flows to be paid on these instruments. As these valuations utilize unobservable inputs, our secured notes and loans payables are classified as Level 3 within the fair value hierarchy. Other liabilities Our Other liabilities include notes payable to related parties. As these notes are short term in nature, the carrying value is deemed to approximate fair value and they are classified as Level 3 within the fair value hierarchy.
Credit Loss Financial Instrument	Accrued interest related to finance receivables is in Other assets on the Consolidated Balance Sheets; however, TMCC measures the fair value of each class of finance receivables using scheduled principal and interest payments. Therefore, accrued interest has been included in the carrying value of each class of finance receivables in the previous tables, along with finance receivables, deferred origination costs, deferred income, and allowance for credit losses.
Revenue Recognition	Voluntary protection contract revenues We receive the contractually determined dealer cost at the inception of the contract. Revenue is then deferred and recognized over the term of the contract according to earnings factors established by management that are based upon historical loss experience. Contracts sold range in term from 3 to 120 months and are typically cancellable at any time. The effect of subsequent cancellations is recorded as an offset to unearned voluntary protection contract revenues in Other liabilities on our Consolidated Balance Sheets. For the years ended March 31, 2022 and 2021, respectively, approximately 82 percent and 83 percent of voluntary protection contract revenues in the Voluntary protection operations segment were accounted for under the guidance for revenue from contracts with customers. The Voluntary protection operations segment defers contractually determined incentives paid to dealers as contract costs for selling voluntary protection products. These costs are recorded in Other assets on our Consolidated Balance Sheets and are amortized to Operating and administrative expenses in the Consolidated Statements of Income using a methodology consistent with the recognition of revenue. The amount of capitalized dealer incentives and the related amortization was not significant to our consolidated financial statements as of and for the years ended March 31, 2022 and 2021.
Insurance Losses and Loss Adjustment Expenses	Insurance earned premiums Revenues from providing coverage under various insurance contracts are recognized over the term of the coverage in relation to the timing and level of anticipated claims. Revenues from insurance policies, net of premiums ceded to reinsurers, are earned over the terms of the respective policies in proportion to the estimated loss development. Management relies on historical loss experience as a basis for establishing earnings factors used to recognize revenue over the term of the contract or policy. Voluntary protection contract expenses and insurance losses Voluntary protection contract expenses and insurance losses include amounts paid and accrued for loss events that are known and have been recorded as claims, estimates of losses incurred but not reported based on actuarial estimates and historical loss development patterns, and loss adjustment expenses that are expected to be incurred in connection with settling and paying these claims. Accruals for unpaid losses, losses incurred but not reported, and loss adjustment expenses are included in Other liabilities on our Consolidated Balance Sheets. These accruals arising from contracts entered into by TMIS are not significant as of March 31, 2022 and 2021. Estimated liabilities are reviewed regularly, and we recognize any adjustments in the periods in which they are determined. If anticipated losses, loss adjustment expenses, and unamortized acquisition and maintenance costs exceed the recorded unearned premium, a premium deficiency is recognized by first charging any unamortized acquisition costs to expense and then by recording a liability for any excess deficiency.
Risk Transfer	Risk Transfer Our voluntary protection operations transfer certain risks to protect us against the impact of unpredictable high severity losses. The amounts recoverable from reinsurers and other companies that assume liabilities relating to our Voluntary protection operations are determined in a manner consistent with the related reinsurance or risk transfer contract. Amounts recoverable from reinsurers and other companies on unpaid losses are recorded as a receivable but are not collectible until the losses are paid. Revenues related to risks transferred are recognized on the same basis as the related revenues from the underlying contracts. Covered losses are recorded as a reduction to Voluntary protection contract expenses and insurance losses.

Lease description	Lease terms may contain renewal and extension options or early termination features. Generally, these options do not impact the lease term because TMCC is not reasonably certain that it will exercise the options. These lease agreements do not impose restrictions on our ability to pay dividends, engage in debt or equity financing transactions or enter into further lease agreements, nor do they have residual value guarantees. We exclude from our Consolidated Balance Sheets leases with a term equal to one year or less and do not separate non-lease components from our real estate leases.
