Interim Financial Data

Interim Financial Data	9 Months Ended

Accounting Policies [Abstract]
Interim Financial Data	N ote 1 – Interim Financial Data Basis of Presentation The information furnished in these unaudited interim consolidated financial statements as of and for the three and nine months ended December 31, 2022 and 2021 has been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). In the opinion of management, the unaudited consolidated financial information reflects all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results for the interim periods presented. The results of operations for the three and nine months ended December 31, 2022, do not necessarily indicate the results which may be expected for the full fiscal year ending March 31, 2023 (“fiscal 2023”). These financial statements should be read in conjunction with the Consolidated Financial Statements and Notes to Consolidated Financial Statements included in Toyota Motor Credit Corporation’s Annual Report on Form 10-K (“Form 10-K”) for the fiscal year ended March 31, 2022 (“fiscal 2022”), which was filed with the Securities and Exchange Commission on June 3, 2022. References herein to “TMCC” denote Toyota Motor Credit Corporation, and references herein to “we”, “our”, and “us” denote Toyota Motor Credit Corporation and its consolidated subsidiaries. Other Matters 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 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 by the end of fiscal 2023. Costs associated with this restructure are not expected to be significant. In fiscal 2022, 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 began to provide inventory financing for Bass Pro Shops, its affiliates, and authorized independent dealers in fiscal 2023, with additional private label services, including consumer financing and voluntary protection products and services, to be added over time. We are leveraging our existing processes and personnel to originate and service the new assets, and we expect to make certain technology investments to support the Bass Pro Shops program. We did not acquire any existing Bass Pro Shops assets or liabilities pursuant to the agreement, and we do not expect launch costs to be significant. Recently Adopted Accounting Guidance On April 1, 2022 , we adopted ASU 2021-05, Lessors-Certain Leases with Variable Lease Payments (Topic 842) , which requires a lessor to classify and account for a lease with variable lease payments that do not depend on a reference index or rate as an operating lease if certain criteria are met. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures. Accounting Guidance Issued But Not Yet Adopted In March 2022, the FASB issued ASU 2022-02, Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures , which eliminates the accounting guidance for Troubled Debt Restructurings by creditors that have adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326 ): Measurement of Credit Losses on Financial Instruments , while enhancing disclosure requirements for certain loan refinancing and restructurings made to borrowers experiencing financial difficulty. Additionally, the ASU adds the requirement to disclose current period gross write-offs by year of origination for financing receivables. This ASU is effective for us on April 1, 2023, with early application permitted. The adoption of this guidance will not have a material impact on our consolidated financial statements and related disclosures.

Marketable Securities [Abstract]
Investments in Marketable Securities	Note 2 – 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 (loss) income, net in our Consolidated Statements of Income. We 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 (loss) income, net in our Consolidated Statements of Income. As of December 31, 2022 and March 31, 2022, we held AFS debt securities for which the fair value option was elected of $ 629 million and $ 674 million , respectively. The difference between the aggregate fair value and the aggregate unpaid principal balance of AFS debt securities for which the fair value option was elected was an unrealized loss of $ 81 million and $ 41 million as of December 31, 2022 and March 31, 2022, respectively. All equity investments are recorded at fair value with changes in fair value included in Investment and other (loss) 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 (loss) income, net in our Consolidated Statements of Income. Investments in marketable securities consisted of the following: December 31, 2022 Amortized Unrealized Unrealized Fair cost gains losses value Available-for-sale debt securities: U.S. government and agency obligations $ 714 $ 1 $ ( 78 ) $ 637 Foreign government and agency obligations 13 - ( 2 ) 11 Municipal debt securities 8 1 ( 1 ) 8 Corporate debt securities 457 1 ( 69 ) 389 Mortgage-backed securities: U.S. government agency 54 - ( 4 ) 50 Non-agency residential 10 - ( 2 ) 8 Non-agency commercial 84 1 ( 8 ) 77 Asset-backed securities 71 - ( 8 ) 63 Total available-for-sale debt securities $ 1,411 $ 4 $ ( 172 ) $ 1,243 Equity investments 3,275 Total investments in marketable securities $ 4,518 Note 2 – Investments in Marketable Securities (Continued) March 31, 2022 Amortized Unrealized Unrealized Fair cost gains losses value Available-for-sale debt securities: U.S. government and agency obligations $ 538 $ - $ ( 29 ) $ 509 Foreign government and agency obligations 26 - ( 3 ) 23 Municipal debt securities 9 1 - 10 Corporate debt securities 598 4 ( 34 ) 568 Mortgage-backed securities: U.S. government agency 20 - - 20 Non-agency residential 11 - ( 1 ) 10 Non-agency commercial 88 1 ( 3 ) 86 Asset-backed securities 82 - ( 4 ) 78 Total available-for-sale debt securities $ 1,372 $ 6 $ ( 74 ) $ 1,304 Equity investments 3,649 Total investments in marketable securities $ 4,953 A portion of our equity investments are investments in funds that are privately placed and managed by an open-end investment management company (the “Trust”). 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. For the three and nine months ended December 31, 2022 , respectively, we had no non-cash investing activities related to in-kind redemptions. For the three months ended December 31, 2021 , we had no non-cash investing activities related to in-kind redemptions. For the nine months ended December 31, 2021, non-cash investing activities related to in-kind redemptions and subsequent purchases amounted to $ 1.1 billion .

Note 2 – Investments in Marketable Securities (Continued) An allowance for credit losses is established when it is determined that a credit loss has occurred. As of December 31, 2022 and March 31, 2022, management determined that credit losses did not exist for securities in an unrealized loss position. This analysis considered a variety of factors including, but not limited to, performance indicators of the issuer, default rates, industry analyst reports, credit ratings, and other relevant information, which indicated that contractual cash flows are expected to occur.

Receivables [Abstract]
Finance Receivables, Net	Note 3 – Finance Receivables, Net Finance receivables, net consists of the 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, net consisted of the following: December 31, March 31, 2022 2022 Retail receivables 1 $ 78,794 $ 73,152 Dealer financing 11,801 10,298 90,595 83,450 Deferred origination costs 1,332 1,330 Deferred income ( 1,149 ) ( 1,102 ) Allowance for credit losses Retail receivables ( 1,426 ) ( 1,195 ) Dealer financing ( 58 ) ( 51 ) Total allowance for credit losses ( 1,484 ) ( 1,246 ) Finance receivables, net $ 89,294 $ 82,432 1 Includes securitized retail receivables of $ 26.0 billion and $ 21.2 billion as of December 31, 2022 and March 31, 2022 , respectively. Accrued interest related to finance receivables is presented in Other assets on the Consolidated Balance Sheets and was $ 284 million and $ 214 million at December 31, 2022 and March 31, 2022, respectively. 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 December 31, 2022 2023 2022 2021 2020 2019 2018 and Prior Total Aging of finance receivables: Current $ 26,023 $ 24,645 $ 15,847 $ 6,395 $ 2,713 $ 1,266 $ 76,889 30-59 days past due 245 518 360 158 92 66 1,439 60-89 days past due 69 155 111 46 29 22 432 90 days or greater past due 33 82 52 22 13 15 217 Total $ 26,370 $ 25,400 $ 16,370 $ 6,621 $ 2,847 $ 1,369 $ 78,977 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 The amortized cost of retail loan portfolio excludes accrued interest of $ 240 million and $ 192 million at December 31, 2022 and March 31, 2022, 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 December 31, 2022 2023 2022 2021 2020 2019 2018 and Prior Revolving loans Total Wholesale Performing $ - $ - $ - $ - $ - $ - $ 3,858 $ 3,858 Credit Watch - - - - - - 30 30 At Risk - - - - - - 2 2 Default - - - - - - - - Wholesale total $ - $ - $ - $ - $ - $ - $ 3,890 $ 3,890 Real estate Performing $ 987 $ 1,213 $ 1,083 $ 148 $ 331 $ 1,021 $ 109 $ 4,892 Credit Watch 5 - - - - - - 5 At Risk - - - - - - - - Default - - - - - - - - Real estate total $ 992 $ 1,213 $ 1,083 $ 148 $ 331 $ 1,021 $ 109 $ 4,897 Working Capital Performing $ 530 $ 383 $ 201 $ 146 $ 127 $ 120 $ 1,507 $ 3,014 Credit Watch - - - - - - - - At Risk - - - - - - - - Default - - - - - - - - Working capital total $ 530 $ 383 $ 201 $ 146 $ 127 $ 120 $ 1,507 $ 3,014 Total $ 1,522 $ 1,596 $ 1,284 $ 294 $ 458 $ 1,141 $ 5,506 $ 11,801 Note 3 – Finance Receivables, Net (Continued) 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 The amortized cost of the dealer products portfolio excludes accrued interest of $ 44 million and $ 22 million at December 31, 2022 and March 31, 2022, respectively. As of December 31, 2022 and March 31, 2022, 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 summarize the aging of the amortized cost basis of our finance receivables by class: December 31, 2022 30 - 59 Days 60 - 89 Days 90 Days or Total Past Current Total Finance 90 Days or ast due and Retail loan $ 1,439 $ 432 $ 217 $ 2,088 $ 76,889 $ 78,977 $ 152 Wholesale - - - - 3,890 3,890 - Real estate - - - - 4,897 4,897 - Working capital - - - - 3,014 3,014 - Total $ 1,439 $ 432 $ 217 $ 2,088 $ 88,690 $ 90,778 $ 152 March 31, 2022 30 - 59 Days 60 - 89 Days 90 Days or Total Past Current Total Finance 90 Days or ast due and 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 Note 3 – Finance Receivables, Net (Continued) Troubled Debt Restructuring For accounts not under bankruptcy protection, the amount of finance receivables modified as a troubled debt restructuring during the three and nine months ended December 31, 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 the three and nine months ended December 31, 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 the three and nine months ended December 31, 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.

Note 4 – Allowance for Credit Losses (Continued) 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. Finance receivables for the dealer products portfolio segment as of December 31, 2022, includes $ 983 million in finance receivables that are guaranteed by Toyota Motor North America, Inc. (“TMNA”), and $ 203 million in finance receivables that are guaranteed by third-party private Toyota distributors. Finance receivables for the dealer products portfolio segment as of December 31, 2021, includes $ 922 million in finance receivables that are guaranteed by TMNA, and $ 183 million in finance receivables that are guaranteed by third-party private Toyota distributors.

Derivatives, Hedging Activities

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 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 (“ISDA”) 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 December 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. Note 6 – Derivatives, Hedging Activities and Interest Expense (Continued) Derivative Activity Impact on Consolidated Financial Statements The following tables show the financial statement line item and amount of our derivative assets and liabilities that are reported on our Consolidated Balance Sheets: December 31, 2022 March 31, 2022 Fair Fair Notional value Notional value Other assets: Interest rate swaps $ 66,902 $ 2,093 $ 64,327 $ 1,425 Foreign currency swaps 129 13 1,594 55 Total $ 67,031 $ 2,106 $ 65,921 $ 1,480 Counterparty netting ( 809 ) ( 761 ) Collateral held ( 1,243 ) ( 658 ) Carrying value of derivative contracts – Other assets $ 54 $ 61 Other liabilities: Interest rate swaps $ 33,198 $ 779 $ 19,903 $ 822 Foreign currency swaps 7,603 1,317 8,102 717 Total $ 40,801 $ 2,096 $ 28,005 $ 1,539 Counterparty netting ( 809 ) ( 761 ) Collateral posted ( 1,286 ) ( 753 ) Carrying value of derivative contracts – Other liabilities $ 1 $ 25 As of December 31, 2022 and March 31, 2022, excess collateral and variation margin held, which we did not use to offset derivative assets and was recorded in Other liabilities on our Consolidated Balance Sheets, was not significant. As of December 31, 2022 and March 31, 2022, we posted initial margin and excess collateral of $ 183 million and $ 132 million, respectively, which we did not use to offset derivative liabilities and was recorded in Other assets on our Consolidated Balance Sheets. Note 6 – Derivatives, Hedging Activities and Interest Expense (Continued) The following table summarizes the components of interest expense, including the location and amount of gains and losses on derivative instruments and related hedged items, as reported in our Consolidated Statements of Income: Three months ended Nine months ended December 31, December 31, 2022 2021 2022 2021 Interest expense on debt $ 845 $ 362 $ 1,914 $ 1,134 Interest (income) expense on derivatives ( 186 ) 23 ( 368 ) 137 Interest expense on debt and derivatives 659 385 1,546 1,271 Losses (gains) on debt denominated in 532 ( 60 ) ( 649 ) ( 338 ) (Gains) losses on foreign currency swaps ( 509 ) 151 947 509 Losses (gains) on U.S. dollar interest rate swaps 83 ( 130 ) 189 ( 387 ) Total interest expense $ 765 $ 346 $ 2,033 $ 1,055 Interest expense on debt and derivatives represents net interest settlements and changes in accruals.

Debt and Credit Facilities	Note 7 – Debt and Credit Facilities Debt and the related weighted average contractual interest rates are summarized as follows: December 31, 2022 March 31, 2022 Face value Carrying value Weighted average Face value Carrying value Weighted average Unsecured notes and loans payable $ 78,958 $ 78,589 3.06 % $ 82,542 $ 82,288 1.30 % Secured notes and loans payable 31,557 31,510 3.23 % 26,907 26,864 1.01 % Total debt $ 110,515 $ 110,099 3.10 % $ 109,449 $ 109,152 1.23 % The carrying value of our debt includes unamortized premiums, discounts, debt issuance costs and the effects of foreign currency translation adjustments. 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. 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 $ 16.8 billion and $ 16.9 billion as of December 31, 2022 and March 31, 2022, 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. 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. 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. Note 7 – Debt and Credit Facilities (Continued) 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”), and other Toyota affiliates are party to a $ 5.0 billion 364-day syndicated bank credit facility, a $ 5.0 billion three-year syndicated bank credit facility, and a $ 5.0 billion five-year syndicated bank credit facility, expiring in fiscal 2024, 2026, and 2028, 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 no t drawn upon and had no outstanding balances as of December 31, 2022 and March 31, 2022. 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 2024. 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 $ 8.0 billion backed by eligible retail finance receivables transferred by us to a special-purpose entity acting as borrower. We utilized $ 3.9 billion and $ 3.2 billion of this facility as of December 31, 2022 and March 31, 2022, respectively. Other Unsecured Credit Agreements TMCC is party to additional unsecured credit facilities with various banks. As of December 31, 2022, TMCC had committed bank credit facilities totaling $ 4.6 billion , of which $ 350 million , $ 2.0 billion , $ 455 million , and $ 1.8 billion mature in fiscal 2023, 2024, 2025, and 2026 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 no t drawn upon and had no outstanding balances as of December 31, 2022 and March 31, 2022. 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. expiring in fiscal 2025. This credit facility was no t drawn upon and had no outstanding balance as of December 31, 2022 and March 31, 2022. 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	9 Months Ended
	Dec. 31, 2022
Variable Interest Entities [Abstract]
Variable Interest Entities	Note 8 – Variable Interest Entities Consolidated Variable Interest Entities We use one or more special purpose entities that are considered Variable Interest Entities (“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: December 31, 2022 VIE Assets VIE Liabilities Net Restricted securitized Other Debt Other Retail finance receivables $ 1,211 $ 25,758 $ 74 $ 22,644 $ 31 Investments in operating leases 595 12,565 20 8,866 14 Total $ 1,806 $ 38,323 $ 94 $ 31,510 $ 45 March 31, 2022 VIE Assets VIE Liabilities Net Restricted securitized Other Debt Other 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 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 $ 1.6 billion and $ 1.7 billion of securities retained by TMCC at December 31, 2022 and March 31, 2022, 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. Note 8 – Variable Interest Entities (Continued) 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 in our Consolidated Balance Sheets at December 31, 2022 and March 31, 2022 and revenues earned from these dealers for the three and nine months ended December 31, 2022 and 2021 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 December 31, 2022 and March 31, 2022 and revenues earned under these relationships for the three and nine months ended December 31, 2022 and 2021 were not significant.

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 also have extended credit facilities to affiliates as described in Note 12 – Related Party Transactions in our fiscal 2022 Form 10-K. Lease Commitments Our operating lease portfolio consists of real estate leases. Total operating lease expense, including payments to affiliates, was $ 25 million and $ 10 million for the first nine months and third quarter of fiscal 2023, as compared to $ 25 million and $ 8 million for the same periods in fiscal 2022 . We have a lease agreement through August 2032 with TMNA for our headquarters facility in Plano, Texas. Commitments under operating lease agreements in the previous table include $ 78 million and $ 84 million for facilities leases with affiliates at December 31, 2022 and March 31, 2022, 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: December 31, Years ending March 31, 2022 2023 $ 5 2024 18 2025 15 2026 14 2027 13 Thereafter 45 Total $ 110 Present value discount ( 12 ) Total operating lease liability $ 98 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: December 31, 2022 ROU assets $ 86 Weighted average remaining lease term (in years) 7.7 Weighted average discount rate 2.86 % 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 December 31, 2022 and March 31, 2022. 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 December 31, 2022, we determined that it is not probable that we will be required to make any material payments in the future. As of December 31, 2022 and March 31, 2022 , no amounts have been recorded under these indemnification provisions. L itigation 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 reasonable possibility of 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.

Income Taxes

Income Taxes	9 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Note 1 0 – Income Taxes Our provision for income taxes was $ 112 million and $ 212 million for the three and nine months ended December 31, 2022, respectively, compared to $ 233 million and $ 697 million for the same periods in fiscal 2022. Our effective tax rate was 24 percent and 25 percent for the three and nine months ended December 31, 2022, respectively, compared to 24 percent and 23 percent for the same periods in fiscal 2022. The decrease in the provision for income taxes for the three and nine months ended December 31, 2022, compared to the same periods in fiscal 2022, was primarily due to the decrease in income before income taxes. The higher effective tax rate for the first nine months of fiscal 2023, compared to the same period in fiscal 2022, was primarily attributable to the decrease in federal plug-in vehicle credits and the increase in unrecognized state tax benefits in the current period. In August 2022, the Inflation Reduction Act ("the Act") was signed into law. The Act modifies climate and clean energy corporate tax provisions, including amendments to the federal tax credit for plug-in vehicles available under current tax law. The Act also includes a 15 percent corporate alternative minimum tax based on modified financial statement net income, applying to tax years beginning after December 31, 2022, which we expect to be applicable in fiscal 2024. As additional guidance related to the Act is issued, we will evaluate any impact to our consolidated financial statements. We do not expect the Act to have a material impact on our results of operations for fiscal 2023. Tax-related Contingencies As of December 31, 2022, we remain under IRS examination for fiscal 2018 through fiscal 2023. We periodically review our uncertain tax positions. Our assessment is based on many factors including any ongoing IRS audits. For the three months ended December 31, 2022, our assessment did not result in a material change in unrecognized tax benefits. Our deferred tax assets include the deferred deduction of allowance for credit losses and residual value loss estimates, mark-to-market adjustment of investment in marketable securities, and other deferred costs. The total deferred tax liability, net of these deferred tax assets, was $ 3.1 billion and $ 1.6 billion at December 31, 2022 and March 31, 2022 , respectively. The increase in our net deferred tax liability was primarily due to the temporary difference between depreciation expense reported for financial statement and that reported for income tax purposes. Although realization of the deferred tax assets is not assured, management believes it is more likely than not that the deferred tax assets will be realized. The amount of the deferred tax assets considered realizable could be reduced if management’s estimates change.

As of December 31, 2022 and March 31, 2022, the subvention receivable from TMNA was $ 94 million and $ 66 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 December 31, 2022 and March 31, 2022 , respectively, we had a net amount payable to TMNA which is recorded in Other payables, net in Other liabilities.

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.

Therefore, accrued interest has been included in the carrying value of each class of finance receivables in the previous tables, along with the finance receivables, deferred origination costs, deferred income, and allowance for credit losses. Finance receivables in the previous tables excludes related party transactions, for which the fair value approximates the carrying value, of $ 57 million and $ 90 million at December 31, 2022 and March 31, 2022, 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.

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 three and nine months ended December 31, 2022 and 2021 . We had $ 2.5 billion and $ 2.7 billion of unearned voluntary protection contract revenues from contracts with customers included in Other liabilities on our Consolidated Balance Sheets as of March 31, 2021 and March 31, 2022, respectively. We recognized $ 198 million and $ 598 million of these balances in voluntary protection contract revenues in our Consolidated Statements of Income during the three and nine months ended December 31, 2022, respectively, compared to $ 170 million and $ 545 million recognized during the same periods in fiscal 2022. As of December 31, 2022, we had unearned voluntary protection contract revenues of $ 2.9 billion included in Other liabilities on our Consolidated Balance Sheets, and with respect to this balance we expect to recognize revenue of $ 218 million during fiscal 2023 , and $ 2.6 billion thereafter . At December 31, 2021 , we had unearned voluntary protection contract revenues of $ 2.6 billion associated with outstanding contracts.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The information furnished in these unaudited interim consolidated financial statements as of and for the three and nine months ended December 31, 2022 and 2021 has been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). In the opinion of management, the unaudited consolidated financial information reflects all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results for the interim periods presented. The results of operations for the three and nine months ended December 31, 2022, do not necessarily indicate the results which may be expected for the full fiscal year ending March 31, 2023 (“fiscal 2023”). These financial statements should be read in conjunction with the Consolidated Financial Statements and Notes to Consolidated Financial Statements included in Toyota Motor Credit Corporation’s Annual Report on Form 10-K (“Form 10-K”) for the fiscal year ended March 31, 2022 (“fiscal 2022”), which was filed with the Securities and Exchange Commission on June 3, 2022. References herein to “TMCC” denote Toyota Motor Credit Corporation, and references herein to “we”, “our”, and “us” denote Toyota Motor Credit Corporation and its consolidated subsidiaries. Other Matters 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 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 by the end of fiscal 2023. Costs associated with this restructure are not expected to be significant. In fiscal 2022, 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 began to provide inventory financing for Bass Pro Shops, its affiliates, and authorized independent dealers in fiscal 2023, with additional private label services, including consumer financing and voluntary protection products and services, to be added over time. We are leveraging our existing processes and personnel to originate and service the new assets, and we expect to make certain technology investments to support the Bass Pro Shops program. We did not acquire any existing Bass Pro Shops assets or liabilities pursuant to the agreement, and we do not expect launch costs to be significant.
Recently Adopted Accounting Guidance	Recently Adopted Accounting Guidance On April 1, 2022 , we adopted ASU 2021-05, Lessors-Certain Leases with Variable Lease Payments (Topic 842) , which requires a lessor to classify and account for a lease with variable lease payments that do not depend on a reference index or rate as an operating lease if certain criteria are met. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures.
Accounting Guidance Issued But Not Yet Adopted	Accounting Guidance Issued But Not Yet Adopted In March 2022, the FASB issued ASU 2022-02, Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures , which eliminates the accounting guidance for Troubled Debt Restructurings by creditors that have adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326 ): Measurement of Credit Losses on Financial Instruments , while enhancing disclosure requirements for certain loan refinancing and restructurings made to borrowers experiencing financial difficulty. Additionally, the ASU adds the requirement to disclose current period gross write-offs by year of origination for financing receivables. This ASU is effective for us on April 1, 2023, with early application permitted. The adoption of this guidance will not have a material impact on our consolidated financial statements and related disclosures.
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 (loss) income, net in our Consolidated Statements of Income. We 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 (loss) income, net in our Consolidated Statements of Income.
Finance Receivables, Net	Finance receivables, net consists of the 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.
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. 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.
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 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 (“ISDA”) 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 December 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	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.
Consolidated Variable Interest Entities	Consolidated Variable Interest Entities We use one or more special purpose entities that are considered Variable Interest Entities (“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.
Revenue Recognition	Voluntary protection operations – Contract revenues 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 three and nine months ended December 31, 2022 and 2021 .

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.
