Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	NOTE A - Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10‑Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. For further information, refer to the consolidated financial statements and footnotes included in PACCAR Inc’s (PACCAR or the Company) Annual Report on Form 10‑K for the year ended December 31, 2021. Earnings per Share : Basic earnings per common share are computed by dividing earnings by the weighted average number of common shares outstanding, plus the effect of any participating securities. Diluted earnings per common share are computed assuming that all potentially dilutive securities are converted into common shares under the treasury stock method. The dilutive and antidilutive options are shown separately in the table below. Three Months Ended March 31, 2022 2021 Additional shares 567,400 792,800 Antidilutive options 1,092,200 583,000 Change in Accounting: In the first quarter of 2022, the Company changed the method of accounting for its U.S. inventories from last-in-first-out (LIFO) to first-in-first-out (FIFO). Inventories valued using the LIFO method comprised 41% of consolidated inventories before deducting the LIFO reserve at December 31, 2021. The Company believes the FIFO method is preferable because it better matches cost with revenues, it results in a more consistent method to value inventory with its foreign subsidiaries and it improves comparability with industry peers. This change increased Retained Earnings by $143.3 million to $11,148.5 million at January 1, 2021. The effects of the change in accounting principle have been retrospectively applied to all periods presented: The effect of the changes made to the Company’s Consolidated Statements of Comprehensive Income was as follows: Three Months Ended March 31, 2021 AS ORIGINALLY REPORTED EFFECT OF CHANGE AS ADJUSTED Truck, Parts and Other Cost of sales and revenues $ 4,690.7 $ (1.0 ) $ 4,689.7 Income Taxes 137.2 .3 137.5 Net Income 470.1 .7 470.8 The cumulative effect of the changes made to the Company’s Consolidated Balance Sheet was as follows: December 31, 2021 AS ORIGINALLY REPORTED EFFECT OF CHANGE AS ADJUSTED Truck, Parts and Other Inventories, net $ 1,768.3 $ 207.7 $ 1,976.0 Other liabilities 1,436.5 51.1 1,487.6 Retained earnings 11,869.2 156.6 12,025.8 The change in accounting policy did not materially affect basic or diluted net income per share or income before income taxes within the Truck, Parts and Other segments for the three months ended March 31, 2021. There was no impact on total net cash provided by operating activities. The following table compares the amounts currently reported to amounts that would have been reported under LIFO in the Consolidated Statements of Comprehensive Income.

Sales And Revenues [Abstract]
Sales and Revenues	NOTE B – Sales and Revenues Truck, Parts and Other The Company enters into sales contracts with customers associated with purchases of the Company’s products and services including trucks, parts, product support, and other related services. Generally, the Company recognizes revenue for the amount of consideration it will receive for delivering a product or service to a customer. Revenue is recognized when the customer obtains control of the product or receives benefits of the service. The Company excludes sales taxes, value added taxes and other related taxes assessed by government agencies from revenue. There are no significant financing components included in product or services revenue since generally customers pay shortly after the products or services are transferred. In the Truck and Parts segment, when the Company grants extended payment terms on selected receivables and charges interest, interest income is recognized when earned. The following table disaggregates Truck, Parts and Other revenues by major sources: Three Months Ended March 31, 2022 2021 Truck Truck sales $ 4,481.1 $ 4,045.0 Revenues from extended warranties, operating leases and other 216.0 188.0 4,697.1 4,233.0 Parts Parts sales 1,348.1 1,125.9 Revenues from dealer services and other 40.8 34.8 1,388.9 1,160.7 Winch sales and other 20.4 19.8 Truck, Parts and Other sales and revenues $ 6,106.4 $ 5,413.5 The Company recognizes truck and parts sales as revenues when control of the products is transferred to customers which generally occurs upon shipment, except for certain truck sales which are subject to a residual value guarantee (RVG) by the Company. The standard payment term for trucks and aftermarket parts is typically within 30 days, but the Company may grant extended payment terms on selected receivables. The Company recognizes revenue for the invoice amount adjusted for estimated sales incentives and returns. Sales incentives and returns are estimated based on historical experience and are adjusted to current period revenue when the most likely amount of consideration the Company expects to receive changes or becomes fixed. Truck and parts sales include a standard product warranty which is included in cost of sales. The Company has elected to treat delivery services as a fulfillment activity with revenues recognized when the customer obtains control of the product. Delivery revenue is included in revenues and the related costs are included in cost of sales. As a practical expedient, the Company is not disclosing truck order backlog, as a significant majority of the backlog has a duration of less than one year. Truck sales with RVGs that allow customers the option to return their truck are accounted for as a sale when the customer does not have an economic incentive to return the truck to the Company, or as an operating lease when the customer does have an economic incentive to return the truck. The estimate of customers’ economic incentive to return the trucks is based on an analysis of historical guaranteed buyback value and estimated market value. When truck sales with RVGs are accounted for as a sale, revenue is recognized when the truck is transferred to the customer less an amount for expected returns. Expected return rates are estimated by using a historical weighted average return rate over an eight-year Aftermarket parts sales allow for returns which are estimated at the time of sale based on historical data. Parts dealer services and other revenues are recognized as services are performed. The following table presents the balance sheet classification of the estimated value of the truck assets to be returned goods assets and the related return liabilities: March 31, 2022 December 31, 2021 ASSETS LIABILITIES ASSETS LIABILITIES Trucks Other current assets $ 262.2 $ 255.7 Accounts payable, accrued expenses and other $ 267.9 $ 264.0 Other noncurrent assets, net 375.7 403.6 Other liabilities 396.0 423.9 $ 637.9 $ 663.9 $ 659.3 $ 687.9 Parts Other current assets $ 80.0 $ 72.9 Accounts payable, accrued expenses and other $ 188.3 $ 172.1 $ 80.0 $ 188.3 $ 72.9 $ 172.1 For contracts accounted for as a sale, the Company’s total commitment to acquire trucks at a guaranteed value was $1,172.1 at March 31, 2022. Revenues from extended warranties, operating leases and other include optional extended warranty and repair and maintenance (R&M) service contracts which can be purchased for periods generally ranging up to five years. The Company defers revenue based on stand-alone observable selling prices when it receives payments in advance and generally recognizes the revenue on a straight-line basis over the warranty or R&M contract periods. See Note F, Product Support Liabilities, in the Notes to the Consolidated Financial Statements for further information. Also included are truck sales with an RVG accounted for as an operating lease. A liability is created for the residual value obligation with the remainder of the proceeds recorded as deferred revenue. The deferred revenue is recognized on a straight-line basis over the guarantee period, which typically ranges from three to five years . Deferred revenue related to trucks sold with an RVG was $ at March 31, 2022 . The Company expects to recognize approximately $ of the remaining deferred revenue in 202 2 , $ in 202 3 , $ 15.1 in 202 4 , $ in 202 5 and $ 3.0 in 202 6 . T otal operating lease revenue from truck sales with RVGs was $ and $ 20.6 for the three months ended March 31, 2022 and 2021, respectively . The Company’s total commitment to acquire trucks at a guaranteed value for contracts accounted for as a lease was $ at March 31, 2022 . Revenue from winch sales and other is primarily derived from the industrial winch business. Winch sales are recognized when the product is transferred to a customer, which generally occurs upon shipment. Also within this category are other revenues not attributable to a reportable segment. Financial Services The Company’s Financial Services segment products include loans to customers collateralized by the vehicles being financed, finance leases for retail customers and dealers, dealer wholesale financing which includes floating-rate wholesale loans to PACCAR dealers for new and used trucks, and operating leases which include rentals on Company owned equipment. Interest income from finance and other receivables is recognized using the interest method. Certain loan origination costs are deferred and amortized to interest income over the expected life of the contracts using the straight-line method which approximates the interest method. Operating lease rental revenue is recognized on a straight-line basis over the term of the lease. Customer contracts may include additional services such as excess mileage, repair and maintenance and other services on which revenue is recognized when earned. The Company’s full-service lease arrangements bundle these additional services. Rents for full-service lease contracts are allocated between lease and non-lease components based on the relative stand-alone price of each component. Taxes, such as sales and use and value added, which are collected by the Company from a customer, are excluded from the measurement of lease income and expenses. Recognition of interest income and rental revenue is suspended (put on non-accrual status) when the receivable becomes more than 90 days past the contractual due date or earlier if some other event causes the Company to determine that collection is not probable. Accordingly, no finance receivables more than 90 days past due were accruing interest at March 31, 2022 or December 31, 2021. Recognition is resumed if the receivable becomes current by the payment of all amounts due under the terms of the existing contract and collection of remaining amounts is considered probable (if not contractually modified) or if the customer makes scheduled payments for three months and collection of remaining amounts is considered probable (if contractually modified). Payments received while the finance receivable is on non-accrual status are applied to interest and principal in accordance with the contractual terms. Finance leases are secured by the trucks and related equipment being leased and the lease terms generally range from three to five years depending on the type and use of the equipment. The lessee is required to either purchase the equipment or guarantee to the Company a stated residual value upon the disposition of the equipment at the end of the finance lease term. Operating lease terms generally range from three to five years. At the end of the operating lease term, the lessee has the option to return the equipment to the Company or purchase the equipment at its fair market value. The Company determines its estimate of the residual value of leased vehicles by considering the length of the lease term, the truck model, the expected usage of the truck and anticipated market demand. If the sales price of the truck at the end of the agreement differs from the Company’s estimated residual value, a gain or loss will result. Future market conditions, changes in government regulations and other factors outside the Company’s control could impact the ultimate sales price of trucks returned under these contracts. Residual values are reviewed regularly and adjusted if market conditions warrant. The following table summarizes Financial Services lease revenues by lease type: Three Months Ended March 31, 2022 2021 Finance lease revenues $ 42.9 $ 47.7 Operating lease revenues 203.6 209.4 Total lease revenues $ 246.5 $ 257.1

Investments Debt And Equity Securities [Abstract]
Investments in Marketable Securities	NOTE C - Investments in Marketable Securities Debt Securities The Company's investments in marketable debt securities are classified as available-for-sale. These investments are stated at fair value and may include an allowance for credit losses. Changes in the allowance for credit losses are recognized in the current period earnings and any unrealized gains or losses, net of tax, are included as a component of accumulated other comprehensive income (loss) (AOCI). The Company utilizes third-party pricing services for all of its marketable debt security valuations. The Company reviews the pricing methodology used by the third‑party pricing services, including the manner employed to collect market information. On a quarterly basis, the Company also performs review and validation procedures on the pricing information received from the third‑party providers. These procedures help ensure the fair value information used by the Company is determined in accordance with applicable accounting guidance. The Company evaluates its investment in marketable debt securities at the end of each reporting period to determine if a decline in fair value is the result of credit losses or unrealized losses. In assessing credit losses, the Company considers the collectability of principal and interest payments by monitoring changes to issuers’ credit ratings, specific credit events associated with individual issuers as well as the credit ratings of any financial guarantor. The Company considers its intent for selling the security and whether it is more likely than not the Company will be able to hold the security until the recovery of any credit losses and unrealized losses. Charges against the allowance for credit losses occur when a security with credit losses is sold or the Company no longer intends to hold that security.

The net activity of dealer direct loans and dealer wholesale financing on new trucks is shown in the operating section of the Condensed Consolidated Statements of Cash Flows since those receivables finance the sale of Company inventory. Allowance for Credit Losses The Company continuously monitors the payment performance of its finance receivables. For large retail finance customers and dealers with wholesale financing, the Company regularly reviews their financial statements and makes site visits and phone contact as appropriate. If the Company becomes aware of circumstances that could cause those customers or dealers to face financial difficulty, whether or not they are past due, the customers are placed on a watch list. The Company modifies loans and finance leases in the normal course of its Financial Services operations. The Company may modify loans and finance leases for commercial reasons or for credit reasons. Modifications for commercial reasons are changes to contract terms for customers that are not considered to be in financial difficulty. Insignificant delays are modifications extending terms up to three months for customers experiencing some short-term financial stress, but not considered to be in financial difficulty. Modifications for credit reasons are changes to contract terms for customers considered to be in financial difficulty. The Company’s modifications typically result in granting more time to pay the contractual amounts owed and charging a fee and interest for the term of the modification. When considering whether to modify customer accounts for credit reasons, the Company evaluates the creditworthiness of the customers and modifies those accounts that the Company considers likely to perform under the modified terms. When the Company modifies a loan or finance lease for credit reasons and grants a concession, the modification is classified as a troubled debt restructuring (TDR). The Company does not typically grant credit modifications for customers that do not meet minimum underwriting standards since the Company normally repossesses the financed equipment in these circumstances. When such modifications do occur, they are considered TDRs. On average, modifications extended contractual terms by approximately four months in 2022 and eight months in 2021, and did not have a significant effect on the weighted average term or interest rate of the total portfolio at March 31, 2022 and December 31, 2021. The Company has developed a systematic methodology for determining the allowance for credit losses for its two portfolio segments, retail and wholesale. The retail segment consists of retail loans and sales-type finance leases, net of unearned interest. The wholesale segment consists of truck inventory financing loans to dealers that are collateralized by trucks and other collateral. The wholesale segment generally has less risk than the retail segment. Wholesale receivables generally are shorter in duration than retail receivables, and the Company requires periodic reporting of the wholesale dealer’s financial condition, conducts periodic audits of the trucks being financed and in many cases, obtains guarantees or other security such as dealership assets. In determining the allowance for credit losses, retail loans and finance leases are evaluated together since they relate to a similar customer base, their contractual terms require regular payment of principal and interest, generally over three to five years, and they are secured by the same type of collateral. The allowance for credit losses consists of both specific and general reserves. The Company individually evaluates certain finance receivables for impairment. Finance receivables that are evaluated individually for impairment consist of all wholesale accounts and certain large retail accounts with past due balances or otherwise determined to be at a higher risk of loss. A finance receivable is impaired if it is considered probable the Company will be unable to collect all contractual interest and principal payments as scheduled. In addition, all retail loans and leases which have been classified as TDRs and all customer accounts over 90 days past due are considered impaired. Generally, impaired accounts are on non-accrual status. Impaired accounts classified as TDRs which have been performing for 90 consecutive days are placed on accrual status if it is deemed probable that the Company will collect all principal and interest payments . Impaired receivables are generally considered collateral dependent. Large balance retail and all wholesale impaired receivables are individually evaluated to determine the appropriate reserve for losses. The determination of reserves for large balance impaired receivables considers the fair value of the associated collateral. When the underlying collateral fair value exceeds the Company’s amortized cost basis, no reserve is recorded. Small balance impaired receivables with similar risk characteristics are evaluated as a separate pool to determine the appropriate reserve for losses using the historical loss information discussed below. The Company evaluates finance receivables that are not individually impaired and share similar risk characteristics on a collective basis and determines the general allowance for credit losses for both retail and wholesale receivables based on historical loss information, using past due account data, current market conditions, and expected changes in future macroeconomic conditions that affect collectability. Historical credit loss data provides relevant information of expected credit losses. The historical information used includes assumptions regarding the likelihood of collecting current and past due accounts, repossession rates, and the recovery rate on the underlying collateral based on used truck values and other pledged collateral or recourse. The Company has developed a range of loss estimates for each of its country portfolios based on historical experience, taking into account loss frequency and severity in both strong and weak truck market conditions. A projection is made of the range of estimated credit losses inherent in the portfolio from which an amount is determined based on current market conditions and other factors impacting the creditworthiness of the Company’s borrowers and their ability to repay. Adjustments to historical loss information are made for changes in forecasted economic conditions that are specific to the industry and markets in which the Company conducts business. The Company utilizes economic forecasts from third party sources In determining the fair value of the collateral, the Company uses a pricing matrix and categorizes the fair value as Level 2 in the hierarchy of fair value measurement. The pricing matrix is reviewed quarterly and updated as appropriate. The pricing matrix considers the make, model and year of the equipment as well as recent sales prices of comparable equipment sold individually, which is the lowest unit of account, through wholesale channels to the Company’s dealers (principal market). The fair value of the collateral also considers the overall condition of the equipment. Accounts are charged off against the allowance for credit losses when, in the judgment of management, they are considered uncollectible, which generally occurs upon repossession of the collateral. Typically the timing between the repossession and charge-off is not significant. In cases where repossession is delayed (e.g., for legal proceedings), the Company records a partial charge-off. The charge-off is determined by comparing the fair value of the collateral, less cost to sell, to the amortized cost basis. For the following credit quality disclosures, finance receivables are classified into two portfolio segments, wholesale and retail. The retail portfolio is further segmented into dealer retail and customer retail. The dealer wholesale segment consists of truck inventory financing to PACCAR dealers. The dealer retail segment consists of loans and leases to participating dealers and franchises that use the proceeds to fund customers’ acquisition of commercial vehicles and related equipment. The customer retail segment consists of loans and leases directly to customers for the acquisition of commercial vehicles and related equipment. Customer retail receivables are further segregated between fleet and owner/operator classes. The fleet class consists of customer retail accounts operating more than five trucks. All other customer retail accounts are considered owner/operator. These two classes have similar measurement attributes, risk characteristics and common methods to monitor and assess credit risk. The allowance for credit losses is summarized as follows: 2022 DEALER CUSTOMER WHOLESALE RETAIL RETAIL OTHER* TOTAL Balance at January 1 $ 3.3 $ 7.1 $ 104.4 $ 2.1 $ 116.9 Provision for losses .4 (1.9 ) 1.2 .5 .2 Charge-offs (2.5 ) (.1 ) (2.6 ) Recoveries 1.9 1.9 Currency translation and other 1.0 .9 1.9 Balance at March 31 $ 3.7 $ 5.2 $ 106.0 $ 3.4 $ 118.3 2021 DEALER CUSTOMER WHOLESALE RETAIL RETAIL OTHER* TOTAL Balance at January 1 $ 3.4 $ 8.4 $ 112.0 $ 3.2 $ 127.0 Provision for losses .1 (.2 ) 3.3 .5 3.7 Charge-offs (3.8 ) (.2 ) (4.0 ) Recoveries 1.5 1.5 Currency translation and other (1.3 ) (.1 ) (1.4 ) Balance at March 31 $ 3.5 $ 8.2 $ 111.7 $ 3.4 $ 126.8 * Operating leases and other trade receivables. Credit Quality The Company's customers are principally concentrated in the transportation industry in North America, Europe, Australia and Brasil. The Company’s portfolio assets are diversified over a large number of customers and dealers with no single customer or dealer balances representing over 5% of the total portfolio assets. The Company retains as collateral a security interest in the related equipment. At the inception of each contract, the Company considers the credit risk based on a variety of credit quality factors including prior payment experience, customer financial information, credit-rating agency ratings, loan-to-value ratios and other internal metrics. On an ongoing basis, the Company monitors credit quality based on past due status and collection experience as there is a meaningful correlation between the past due status of customers and the risk of loss. The Company has three credit quality indicators: performing, watch and at-risk. Performing accounts pay in accordance with the contractual terms and are not considered high-risk. Watch accounts include accounts 31 to 90 days past due and large accounts that are performing but are considered to be high‑risk. Watch accounts are not impaired. At-risk accounts are accounts that are impaired, including TDRs, accounts over 90 days past due and other accounts on non-accrual status. The tables below summarize the amortized cost basis of the Company’s finance receivables within each credit quality indicator by year of origination and portfolio class.

The Company records the vehicles as used truck inventory included in Financial Services Other assets on the Consolidated Balance Sheets. The balance of repossessed inventory at March 31, 2022 and December 31, 2021 was $3.2 and $4.7, respectively. Proceeds from the sales of repossessed assets were $7.8 and $16.1 for the three months ended March 31, 2022 and 2021, respectively. These amounts are included in Proceeds from asset disposals in the Condensed Consolidated Statements of Cash Flows.

Product Warranties Disclosures [Abstract]
Product Support Liabilities	NOTE F - Product Support Liabilities Product support liabilities include estimated future payments related to product warranties and deferred revenues on optional extended warranties and R&M. The Company generally offers one year warranties covering most of its vehicles and related aftermarket parts. For vehicles equipped with engines manufactured by PACCAR, the Company generally offers two year warranties on the engine. Specific terms and conditions vary depending on the product and the country of sale. Optional extended warranty and R&M contracts can be purchased for periods which generally range up to five years. Warranty expenses and reserves are estimated and recorded at the time products or contracts are sold based on historical and current data and reasonable expectations for the future regarding the frequency and cost of warranty claims, net of any recoveries. The Company periodically assesses the adequacy of its recorded liabilities and adjusts them as appropriate to reflect actual experience. Revenue from extended warranty and R&M contracts is deferred and recognized to income generally on a straight-line basis over the contract period. Warranty and R&M costs on these contracts are recognized as incurred. Changes in product support liabilities are summarized as follows: WARRANTY RESERVES 2022 2021 Balance at January 1 $ 344.3 $ 389.7 Cost accruals 73.6 80.5 Payments (88.2 ) (109.6 ) Change in estimates for pre-existing warranties 23.1 18.8 Currency translation and other (3.0 ) (2.5 ) Balance at March 31 $ 349.8 $ 376.9 DEFERRED REVENUES ON EXTENDED WARRANTIES AND R&M CONTRACTS 2022 2021 Balance at January 1 $ 775.2 $ 795.8 Deferred revenues 146.1 116.0 Revenues recognized (119.3 ) (117.1 ) Currency translation (9.1 ) (10.0 ) Balance at March 31 $ 792.9 $ 784.7 The Company expects to recognize approximately $202.0 of the remaining deferred revenue on extended warranties and R&M contracts in 2022, $261.0 in 2023, $184.8 in 2024, $90.4 in 2025, $35.1 in 2026 and $19.6 thereafter.

Segment Reporting [Abstract]
Segment Information	NOTE I - Segment Information PACCAR operates in three principal segments: Truck, Parts and Financial Services. The Company evaluates the performance of its Truck and Parts segments based on operating profits, which excludes investment income, other income and expense and income taxes. The Financial Services segment’s performance is evaluated based on income before income taxes. The accounting policies of the reportable segments are the same as those applied in the consolidated financial statements as described in Note A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. Truck and Parts The Truck segment includes the design and manufacture of high-quality, light-, medium- and heavy-duty commercial trucks and the Parts segment includes the distribution of aftermarket parts for trucks and related commercial vehicles, both of which are sold through the same network of independent dealers. These segments derive a large proportion of their revenues and operating profits from operations in North America and Europe. The Truck segment incurs substantial costs to design, manufacture and sell trucks to its customers. The sale of new trucks provides the Parts segment with the basis for parts sales that may continue over the life of the truck, but are generally concentrated in the first five years after truck delivery. To reflect the benefit the Parts segment receives from costs incurred by the Truck segment, certain expenses are allocated from the Truck segment to the Parts segment. The expenses allocated are based on a percentage of the average annual expenses for factory overhead, engineering, research and development and SG&A expenses for the preceding five years. The allocation is based on the ratio of the average parts direct margin dollars (net sales less material and labor costs) to the total truck and parts direct margin dollars for the previous five years. The Company believes such expenses have been allocated on a reasonable basis. Truck segment assets related to the indirect expense allocation are not allocated to the Parts segment. Financial Services The Financial Services segment derives its earnings primarily from financing or leasing of PACCAR products and services provided to truck customers and dealers. Revenues are primarily generated from operations in North America and Europe. In Europe, the Financial Services and Truck segments centralized the marketing of used trucks, including those units sold by the Truck segment subject to an RVG. When a customer returns the truck at the end of the RVG contract, the Company’s Truck segment records a reduction in an RVG liability and the Company’s Financial Services segment records a used truck asset and revenue from the subsequent sale. Certain gains and losses from the sale of these used trucks are shared with the Truck segment. Other Included in Other is the Company’s industrial winch manufacturing business as well as sales, income and expenses not attributable to a reportable segment. Other also includes non-service cost components of pension expense and a portion of corporate expenses.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	NOTE J - Derivative Financial Instruments As part of its risk management strategy, the Company enters into derivative contracts to hedge against the risks of interest rates, foreign currency rates and commodity prices. Certain derivative instruments designated as fair value hedges, cash flow hedges or net investment hedges are subject to hedge accounting. Derivative instruments that are not subject to hedge accounting are held as derivatives not designated as hedging instruments. The Company’s policies prohibit the use of derivatives for speculation or trading. At the inception of each hedge relationship, the Company documents its risk management objectives, procedures and accounting treatment. All of the Company’s interest-rate, commodity as well as certain foreign-exchange contracts are transacted under International Swaps and Derivatives Association (ISDA) master agreements. Each agreement permits the net settlement of amounts owed in the event of default and certain other termination events. For derivative financial instruments, the Company has elected not to offset derivative positions in the balance sheet with the same counterparty under the same agreements and is not required to post or receive collateral. Exposure limits and minimum credit ratings are used to minimize the risks of counterparty default. The Company’s maximum exposure to potential default of its derivative counterparties is limited to the asset position of its derivative portfolio. The asset position of the Company’s derivative portfolio was $65.8 at March 31, 2022. The Company assesses hedges at inception and on an ongoing basis to determine that the designated derivatives are highly effective in offsetting changes in fair values or cash flow of the hedged items. Hedge accounting is discontinued prospectively when the Company determines that a derivative financial instrument has ceased to be a highly effective hedge. Cash flows from derivative instruments are included in Operating activities in the Condensed Consolidated Statements of Cash Flows. Interest-Rate Contracts: The Company enters into various interest-rate contracts, including interest-rate swaps and cross currency interest-rate swaps. Interest-rate swaps involve the exchange of fixed for floating rate or floating for fixed rate interest payments based on the contractual notional amounts in a single currency. Cross currency interest-rate swaps involve the exchange of notional amounts and interest payments in different currencies. The Company is exposed to interest-rate and exchange-rate risk caused by market volatility as a result of its borrowing activities. The objective of these contracts is to mitigate the fluctuations on earnings, cash flows and fair value of borrowings. Net amounts paid or received are reflected as adjustments to interest expense. At March 31, 2022, the notional amount of the Company’s interest-rate contracts was $2,968.8. Notional maturities for all interest-rate contracts are $791.4 for the remainder of 2022, $714.3 for 2023, $552.1 for 2024, $577.5 for 2025, $217.4 for 2026, $61.1 for 2027 and $55.0 thereafter. Foreign-Exchange Contracts: The Company enters into foreign-exchange contracts to hedge certain anticipated transactions and assets and liabilities denominated in foreign currencies, particularly the Canadian dollar, the euro, the British pound, the Australian dollar, the Brazilian real and the Mexican peso. The objective is to reduce fluctuations in earnings and cash flows associated with changes in foreign currency exchange rates. The Company enters into foreign-exchange contracts as net investment hedges to reduce the foreign currency exposure from its investments in foreign subsidiaries. At March 31, 2022, the notional amount of the outstanding foreign-exchange contracts was $2,223.0. Foreign-exchange contracts mature within two years. Commodity Contracts: The Company enters into commodity forward contracts to hedge the prices of certain commodities used in the production of trucks. The objective is to reduce the fluctuation in earnings and cash flows associated with adverse movement in commodity prices. At March 31, 2022, the notional amount of the outstanding commodity contracts was $116.9. Commodity contracts mature within one year. The following table presents the balance sheet classification, fair value, gross and pro forma net amounts of derivative financial instruments: March 31, 2022 December 31, 2021 ASSETS LIABILITIES ASSETS LIABILITIES Derivatives designated under hedge accounting: Interest-rate contracts: Financial Services: Other assets $ 24.0 $ 30.8 Deferred taxes and other liabilities $ 80.4 $ 54.4 Foreign-exchange contracts: Truck, Parts and Other: Other current assets 8.9 25.3 Accounts payable, accrued expenses and other 49.0 15.8 Financial Services: Other current assets 2.5 Deferred taxes and other liabilities 14.6 .1 Commodity contracts: Truck, Parts and Other: Other current assets 31.4 Accounts payable, accrued expenses and other 16.9 $ 64.3 $ 144.0 $ 58.6 $ 87.2 Derivatives not designated as hedging instruments: Foreign-exchange contracts: Truck, Parts and Other: Other current assets $ 1.5 $ 1.0 Accounts payable, accrued expenses and other $ 1.8 $ 1.1 Financial Services: Other assets .1 Deferred taxes and other liabilities .5 .2 $ 1.5 $ 2.3 $ 1.1 $ 1.3 Gross amounts recognized in Balance Sheets $ 65.8 $ 146.3 $ 59.7 $ 88.5 Less amounts not offset in financial instruments: Truck, Parts and Other: Foreign-exchange contracts $ (2.9 ) $ (2.9 ) $ (2.7 ) $ (2.7 ) Financial Services: Foreign-exchange contracts (.2 ) (.2 ) Interest-rate contracts (7.1 ) (7.1 ) (12.8 ) (12.8 ) Pro forma net amount $ 55.8 $ 136.3 $ 44.0 $ 72.8 The following table presents the amount of loss (gain) from derivative financial instruments recorded in the Consolidated Statements of Comprehensive Income: Three Months Ended March 31, 2022 2021 INTEREST- FOREIGN- INTEREST- FOREIGN- RATE EXCHANGE RATE EXCHANGE Truck, Parts and Other: Net sales and revenues Cash flow hedges $ 6.9 $ 8.5 Cost of sales and revenues Cash flow hedges 3.7 2.3 Derivatives not designated as hedging instruments (.5 ) (.4 ) Interest and other (income), net Cash flow hedges .3 .2 Net investment hedges (1.3 ) (1.0 ) Derivatives not designated as hedging instruments 1.9 (1.4 ) $ 11.0 $ 8.2 Financial Services: Interest and other borrowing expenses Cash flow hedges $ (6.6 ) $ (22.7 ) Fair value hedges (.1 ) .2 Derivatives not designated as hedging instruments $ .1 $ (1.8 ) $ (6.7 ) $ .1 $ (22.5 ) $ (1.8 ) Total $ (6.7 ) $ 11.1 $ (22.5 ) $ 6.4 Utilization of commodity hedging was initiated in Q3 2021. The loss from commodity contracts recorded in cost of sales and revenue was $4.9 for the three months ended March 31, 2022. Fair Value Hedges Changes in the fair value of derivatives designated as fair value hedges are recorded in earnings together with the changes in fair value of the hedged item attributable to the risk being hedged. The following table presents the amounts recorded on the Consolidated Balance Sheets related to cumulative basis adjustments for fair value hedges: March 31 December 31 2022 2021 Financial Services Term notes: Carrying amount of the hedged liabilities $ 431.9 $ 472.0 Cumulative 24.4 8.7 The above table excludes the cumulative basis adjustments on discontinued hedge relationships of $.6 and $.1 as of March 31, 2022 and December 31, 2021, respectively. Cash Flow Hedges Substantially all of the Company’s interest-rate contracts and some foreign-exchange contracts and all commodity contracts have been designated as cash flow hedges. Changes in the fair value of derivatives designated as cash flow hedges are recorded in AOCI. Amounts in AOCI are reclassified into net income in the same period in which the hedged transaction affects earnings. The maximum length of time over which the Company is hedging its exposure to the variability in future cash flows is 6.3 years. The following tables presents the pre-tax effects of gain (loss) on cash flow hedges recognized in other comprehensive income (loss) (OCI): Three Months Ended March 31, 2022 2021 INTEREST- FOREIGN- INTEREST- FOREIGN- RATE EXCHANGE RATE EXCHANGE Gain (loss) recognized in OCI: Truck, Parts and Other $ (28.4 ) $ 2.1 Financial Services $ 19.9 (.5 ) $ 33.7 (1.8 ) $ 19.9 $ (28.9 ) $ 33.7 $ .3 Utilization of commodity hedging was initiated in Q3 2021. The pre-tax effects of gain on commodity hedges recognized in other comprehensive income (loss) (OCI) for Truck, Parts and Other was a gain of $35.9 for the three months ended March 31, 2022. The amount of loss recorded in AOCI at March 31, 2022 that is estimated to be reclassified into earnings in the following 12 months if interest rates and exchange rates remain unchanged is approximately $2.3, net of taxes. The fixed interest earned on finance receivables will offset the amount recognized in interest expense, resulting in a stable interest margin consistent with the Company’s risk management strategy. The amount of gains (losses) reclassified out of AOCI into net income based on the probability that the original forecasted transactions would not occur was $.1 and ($.1) for the three months ended March 31, 2022 and 2021, respectively. Net Investment Hedges Changes in the fair value of derivatives designated as net investment hedges are recorded in AOCI as an adjustment to the Cumulative Translation Adjustment (CTA). At March 31, 2022, the notional amount of the outstanding net investment hedges was $347.0. For the three months ended March 31, 2022, the pre-tax gain recognized in OCI for the net investment hedges was $18.2. Derivatives Not Designated As Hedging Instruments For other risk management purposes, the Company enters into derivative instruments that do not qualify for hedge accounting. These derivative instruments are used to mitigate the risk of market volatility arising from borrowings and foreign currency denominated transactions. Changes in the fair value of derivatives not designated as hedging instruments are recorded in earnings in the period in which the change occurs.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE K - Fair Value Measurements Fair value represents 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 Level 1 – Valuations are based on quoted prices that the Company has the ability to obtain in actively traded markets for identical assets or liabilities. Since valuations are based on quoted prices that are readily and regularly available in an active market or exchange traded market, valuation of these instruments does not require a significant degree of judgment. Level 2 – Valuations are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3 – Valuations are based on model-based techniques for which some or all of the assumptions are obtained from indirect market information that is significant to the overall fair value measurement and which require a significant degree of management judgment. The Company uses the following methods and assumptions to measure fair value for assets and liabilities subject to recurring fair value measurements. Marketable Debt Securities: The Company’s marketable debt securities consist of municipal bonds, government obligations, investment-grade corporate obligations, commercial paper, asset-backed securities and term deposits. The fair value of U.S. government obligations is determined using the market approach and is based on quoted prices in active markets and are categorized as Level 1. The fair value of U.S. government agency obligations, non-U.S. government bonds, municipal bonds, corporate bonds, asset-backed securities, commercial paper and term deposits is determined using the market approach and is primarily based on matrix pricing as a practical expedient which does not rely exclusively on quoted prices for a specific security. Significant inputs used to determine fair value include interest rates, yield curves, credit rating of the security and other observable market information and are categorized as Level 2. Marketable Equity Securities: The Company’s equity securities are traded on active exchanges and are classified as Level 1. Derivative Financial Instruments: The Company’s derivative contracts consist of interest-rate swaps, cross currency swaps, foreign currency exchange and commodity contracts. These derivative contracts are traded over the counter, and their fair value is determined using industry standard valuation models, which are based on the income approach (i.e., discounted cash flows). The significant observable inputs into the valuation models include interest rates, yield curves, currency exchange rates, credit default swap spreads, forward rates and commodity prices and are categorized as Level 2. Assets and Liabilities Subject to Recurring Fair Value Measurement The Company’s assets and liabilities subject to recurring fair value measurements are either Level 1 or Level 2 as follows: At March 31, 2022 LEVEL 1 LEVEL 2 TOTAL Assets: Marketable debt securities U.S. tax-exempt securities $ 440.1 $ 440.1 U.S. taxable municipal/ provincial bonds 175.3 175.3 U.S. corporate securities 205.1 205.1 U.S. government and agency securities $ 88.4 88.4 Non-U.S. corporate securities 431.1 431.1 Non-U.S. government securities 70.7 70.7 Other debt securities 97.9 97.9 Total marketable debt securities $ 88.4 $ 1,420.2 $ 1,508.6 Marketable equity securities $ 6.6 $ 6.6 Total marketable securities $ 95.0 $ 1,420.2 $ 1,515.2 Derivatives Cross currency swaps $ 20.2 $ 20.2 Interest-rate swaps 3.8 3.8 Foreign-exchange contracts 10.4 10.4 Commodity contracts 31.4 31.4 Total derivative assets $ 65.8 $ 65.8 Liabilities: Derivatives Cross currency swaps $ 53.9 $ 53.9 Interest-rate swaps 26.5 26.5 Foreign-exchange contracts 65.9 65.9 Total derivative liabilities $ 146.3 $ 146.3 At December 31, 2021 LEVEL 1 LEVEL 2 TOTAL Assets: Marketable debt securities U.S. tax-exempt securities $ 432.5 $ 432.5 U.S. taxable municipal/ provincial bonds 191.6 191.6 U.S. corporate securities 207.4 207.4 U.S. government and agency securities $ 96.4 96.4 Non-U.S. corporate securities 442.8 442.8 Non-U.S. government securities 75.0 75.0 Other debt securities 100.0 100.0 Total marketable debt securities $ 96.4 $ 1,449.3 $ 1,545.7 Marketable equity securities $ 13.7 $ 13.7 Total marketable securities $ 110.1 $ 1,449.3 $ 1,559.4 Derivatives Cross currency swaps $ 18.2 $ 18.2 Interest-rate swaps 12.6 12.6 Foreign-exchange contracts 28.9 28.9 Total derivative assets $ 59.7 $ 59.7 Liabilities: Derivatives Cross currency swaps $ 33.1 $ 33.1 Interest-rate swaps 21.3 21.3 Foreign-exchange contracts 17.2 17.2 Commodity contracts 16.9 16.9 Total derivative liabilities $ 88.5 $ 88.5 Fair Value Disclosure of Other Financial Instruments For financial instruments that are not recognized at fair value, the Company uses the following methods and assumptions to determine the fair value. These instruments are categorized as Level 2, except cash which is categorized as Level 1 and fixed rate loans which are categorized as Level 3. Cash and Cash Equivalents: Carrying amounts approximate fair value. Financial Services Net Receivables: For floating rate loans, wholesale financing and operating lease and other trade receivables, carrying values approximate fair values. For fixed rate loans, fair values are estimated using the income approach by discounting cash flows to their present value based on assumptions regarding the credit and market risks to approximate current rates for comparable loans. Finance lease receivables and related allowance for credit losses have been excluded from the accompanying table. Debt: The carrying amounts of Financial Services commercial paper, variable rate bank loans and variable rate term notes approximate fair value. For fixed rate debt, fair values are estimated using the income approach by discounting cash flows to their present value based on current rates for comparable debt. The Company’s estimate of fair value for fixed rate loans and debt that are not carried at fair value was as follows: March 31, 2022 December 31, 2021 CARRYING FAIR CARRYING FAIR AMOUNT VALUE AMOUNT VALUE Assets: Financial Services fixed rate loans $ 6,383.0 $ 6,237.4 $ 6,011.7 $ 6,018.2 Liabilities: Financial Services fixed rate debt 6,542.8 6,528.5 6,905.7 6,935.1

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE M – Commitments and Contingencies On July 19, 2016, the European Commission (EC) concluded its investigation of all major European truck manufacturers and reached a settlement with DAF Trucks N.V., DAF Trucks Deutschland GmbH and PACCAR Inc (collectively “the Company”). Following the settlement, certain EC-related claims and lawsuits have been filed in various European jurisdictions against all major European truck manufacturers including the Company and certain subsidiaries. These claims and lawsuits include a number of collective proceedings, including proposed class actions in the United Kingdom, alleging EC-related claims and seeking unspecified damages. In certain jurisdictions, the limitations period has not yet expired and additional claimants may bring EC-related claims and lawsuits against the Company or its subsidiaries. The legal proceedings are continuing to move through the court systems in the various jurisdictions with some larger cases scheduled for trial in 2022. While the Company believes it has meritorious defenses to all EC-related claims and lawsuits, the final disposition of all such claims and lawsuits will likely take a significant period of time to resolve and the final outcomes are highly uncertain. The Company cannot at this time reasonably estimate a range of loss, if any, that may result. An adverse final decision involving significant numbers of DAF truck sales could have a material impact on the Company’s results of operations and cash flows. PACCAR is also a defendant in various other legal proceedings and, in addition, there are various other contingent liabilities arising in the normal course of business. After consultation with legal counsel, management does not anticipate that disposition of these various other proceedings and contingent liabilities will have a material effect on the consolidated financial statements.

Accounting Policies [Abstract]
Sales and Revenues	Truck, Parts and Other The Company enters into sales contracts with customers associated with purchases of the Company’s products and services including trucks, parts, product support, and other related services. Generally, the Company recognizes revenue for the amount of consideration it will receive for delivering a product or service to a customer. Revenue is recognized when the customer obtains control of the product or receives benefits of the service. The Company excludes sales taxes, value added taxes and other related taxes assessed by government agencies from revenue. There are no significant financing components included in product or services revenue since generally customers pay shortly after the products or services are transferred. In the Truck and Parts segment, when the Company grants extended payment terms on selected receivables and charges interest, interest income is recognized when earned. The following table disaggregates Truck, Parts and Other revenues by major sources: Three Months Ended March 31, 2022 2021 Truck Truck sales $ 4,481.1 $ 4,045.0 Revenues from extended warranties, operating leases and other 216.0 188.0 4,697.1 4,233.0 Parts Parts sales 1,348.1 1,125.9 Revenues from dealer services and other 40.8 34.8 1,388.9 1,160.7 Winch sales and other 20.4 19.8 Truck, Parts and Other sales and revenues $ 6,106.4 $ 5,413.5 The Company recognizes truck and parts sales as revenues when control of the products is transferred to customers which generally occurs upon shipment, except for certain truck sales which are subject to a residual value guarantee (RVG) by the Company. The standard payment term for trucks and aftermarket parts is typically within 30 days, but the Company may grant extended payment terms on selected receivables. The Company recognizes revenue for the invoice amount adjusted for estimated sales incentives and returns. Sales incentives and returns are estimated based on historical experience and are adjusted to current period revenue when the most likely amount of consideration the Company expects to receive changes or becomes fixed. Truck and parts sales include a standard product warranty which is included in cost of sales. The Company has elected to treat delivery services as a fulfillment activity with revenues recognized when the customer obtains control of the product. Delivery revenue is included in revenues and the related costs are included in cost of sales. As a practical expedient, the Company is not disclosing truck order backlog, as a significant majority of the backlog has a duration of less than one year. Truck sales with RVGs that allow customers the option to return their truck are accounted for as a sale when the customer does not have an economic incentive to return the truck to the Company, or as an operating lease when the customer does have an economic incentive to return the truck. The estimate of customers’ economic incentive to return the trucks is based on an analysis of historical guaranteed buyback value and estimated market value. When truck sales with RVGs are accounted for as a sale, revenue is recognized when the truck is transferred to the customer less an amount for expected returns. Expected return rates are estimated by using a historical weighted average return rate over an eight-year Aftermarket parts sales allow for returns which are estimated at the time of sale based on historical data. Parts dealer services and other revenues are recognized as services are performed. The following table presents the balance sheet classification of the estimated value of the truck assets to be returned goods assets and the related return liabilities: March 31, 2022 December 31, 2021 ASSETS LIABILITIES ASSETS LIABILITIES Trucks Other current assets $ 262.2 $ 255.7 Accounts payable, accrued expenses and other $ 267.9 $ 264.0 Other noncurrent assets, net 375.7 403.6 Other liabilities 396.0 423.9 $ 637.9 $ 663.9 $ 659.3 $ 687.9 Parts Other current assets $ 80.0 $ 72.9 Accounts payable, accrued expenses and other $ 188.3 $ 172.1 $ 80.0 $ 188.3 $ 72.9 $ 172.1 For contracts accounted for as a sale, the Company’s total commitment to acquire trucks at a guaranteed value was $1,172.1 at March 31, 2022. Revenues from extended warranties, operating leases and other include optional extended warranty and repair and maintenance (R&M) service contracts which can be purchased for periods generally ranging up to five years. The Company defers revenue based on stand-alone observable selling prices when it receives payments in advance and generally recognizes the revenue on a straight-line basis over the warranty or R&M contract periods. See Note F, Product Support Liabilities, in the Notes to the Consolidated Financial Statements for further information. Also included are truck sales with an RVG accounted for as an operating lease. A liability is created for the residual value obligation with the remainder of the proceeds recorded as deferred revenue. The deferred revenue is recognized on a straight-line basis over the guarantee period, which typically ranges from three to five years . Deferred revenue related to trucks sold with an RVG was $ at March 31, 2022 . The Company expects to recognize approximately $ of the remaining deferred revenue in 202 2 , $ in 202 3 , $ 15.1 in 202 4 , $ in 202 5 and $ 3.0 in 202 6 . T otal operating lease revenue from truck sales with RVGs was $ and $ 20.6 for the three months ended March 31, 2022 and 2021, respectively . The Company’s total commitment to acquire trucks at a guaranteed value for contracts accounted for as a lease was $ at March 31, 2022 . Revenue from winch sales and other is primarily derived from the industrial winch business. Winch sales are recognized when the product is transferred to a customer, which generally occurs upon shipment. Also within this category are other revenues not attributable to a reportable segment.
Inventories	Inventories are stated at the lower of cost or market. Cost of inventories is determined principally by the first-in, first-out (FIFO) method.
Allowance for Credit Losses	Allowance for Credit Losses The Company continuously monitors the payment performance of its finance receivables. For large retail finance customers and dealers with wholesale financing, the Company regularly reviews their financial statements and makes site visits and phone contact as appropriate. If the Company becomes aware of circumstances that could cause those customers or dealers to face financial difficulty, whether or not they are past due, the customers are placed on a watch list. The Company modifies loans and finance leases in the normal course of its Financial Services operations. The Company may modify loans and finance leases for commercial reasons or for credit reasons. Modifications for commercial reasons are changes to contract terms for customers that are not considered to be in financial difficulty. Insignificant delays are modifications extending terms up to three months for customers experiencing some short-term financial stress, but not considered to be in financial difficulty. Modifications for credit reasons are changes to contract terms for customers considered to be in financial difficulty. The Company’s modifications typically result in granting more time to pay the contractual amounts owed and charging a fee and interest for the term of the modification. When considering whether to modify customer accounts for credit reasons, the Company evaluates the creditworthiness of the customers and modifies those accounts that the Company considers likely to perform under the modified terms. When the Company modifies a loan or finance lease for credit reasons and grants a concession, the modification is classified as a troubled debt restructuring (TDR). The Company does not typically grant credit modifications for customers that do not meet minimum underwriting standards since the Company normally repossesses the financed equipment in these circumstances. When such modifications do occur, they are considered TDRs. On average, modifications extended contractual terms by approximately four months in 2022 and eight months in 2021, and did not have a significant effect on the weighted average term or interest rate of the total portfolio at March 31, 2022 and December 31, 2021. The Company has developed a systematic methodology for determining the allowance for credit losses for its two portfolio segments, retail and wholesale. The retail segment consists of retail loans and sales-type finance leases, net of unearned interest. The wholesale segment consists of truck inventory financing loans to dealers that are collateralized by trucks and other collateral. The wholesale segment generally has less risk than the retail segment. Wholesale receivables generally are shorter in duration than retail receivables, and the Company requires periodic reporting of the wholesale dealer’s financial condition, conducts periodic audits of the trucks being financed and in many cases, obtains guarantees or other security such as dealership assets. In determining the allowance for credit losses, retail loans and finance leases are evaluated together since they relate to a similar customer base, their contractual terms require regular payment of principal and interest, generally over three to five years, and they are secured by the same type of collateral. The allowance for credit losses consists of both specific and general reserves. The Company individually evaluates certain finance receivables for impairment. Finance receivables that are evaluated individually for impairment consist of all wholesale accounts and certain large retail accounts with past due balances or otherwise determined to be at a higher risk of loss. A finance receivable is impaired if it is considered probable the Company will be unable to collect all contractual interest and principal payments as scheduled. In addition, all retail loans and leases which have been classified as TDRs and all customer accounts over 90 days past due are considered impaired. Generally, impaired accounts are on non-accrual status. Impaired accounts classified as TDRs which have been performing for 90 consecutive days are placed on accrual status if it is deemed probable that the Company will collect all principal and interest payments . Impaired receivables are generally considered collateral dependent. Large balance retail and all wholesale impaired receivables are individually evaluated to determine the appropriate reserve for losses. The determination of reserves for large balance impaired receivables considers the fair value of the associated collateral. When the underlying collateral fair value exceeds the Company’s amortized cost basis, no reserve is recorded. Small balance impaired receivables with similar risk characteristics are evaluated as a separate pool to determine the appropriate reserve for losses using the historical loss information discussed below. The Company evaluates finance receivables that are not individually impaired and share similar risk characteristics on a collective basis and determines the general allowance for credit losses for both retail and wholesale receivables based on historical loss information, using past due account data, current market conditions, and expected changes in future macroeconomic conditions that affect collectability. Historical credit loss data provides relevant information of expected credit losses. The historical information used includes assumptions regarding the likelihood of collecting current and past due accounts, repossession rates, and the recovery rate on the underlying collateral based on used truck values and other pledged collateral or recourse. The Company has developed a range of loss estimates for each of its country portfolios based on historical experience, taking into account loss frequency and severity in both strong and weak truck market conditions. A projection is made of the range of estimated credit losses inherent in the portfolio from which an amount is determined based on current market conditions and other factors impacting the creditworthiness of the Company’s borrowers and their ability to repay. Adjustments to historical loss information are made for changes in forecasted economic conditions that are specific to the industry and markets in which the Company conducts business. The Company utilizes economic forecasts from third party sources In determining the fair value of the collateral, the Company uses a pricing matrix and categorizes the fair value as Level 2 in the hierarchy of fair value measurement. The pricing matrix is reviewed quarterly and updated as appropriate. The pricing matrix considers the make, model and year of the equipment as well as recent sales prices of comparable equipment sold individually, which is the lowest unit of account, through wholesale channels to the Company’s dealers (principal market). The fair value of the collateral also considers the overall condition of the equipment. Accounts are charged off against the allowance for credit losses when, in the judgment of management, they are considered uncollectible, which generally occurs upon repossession of the collateral. Typically the timing between the repossession and charge-off is not significant. In cases where repossession is delayed (e.g., for legal proceedings), the Company records a partial charge-off. The charge-off is determined by comparing the fair value of the collateral, less cost to sell, to the amortized cost basis.
Product Support Liabilities	Product support liabilities include estimated future payments related to product warranties and deferred revenues on optional extended warranties and R&M. The Company generally offers one year warranties covering most of its vehicles and related aftermarket parts. For vehicles equipped with engines manufactured by PACCAR, the Company generally offers two year warranties on the engine. Specific terms and conditions vary depending on the product and the country of sale. Optional extended warranty and R&M contracts can be purchased for periods which generally range up to five years. Warranty expenses and reserves are estimated and recorded at the time products or contracts are sold based on historical and current data and reasonable expectations for the future regarding the frequency and cost of warranty claims, net of any recoveries. The Company periodically assesses the adequacy of its recorded liabilities and adjusts them as appropriate to reflect actual experience. Revenue from extended warranty and R&M contracts is deferred and recognized to income generally on a straight-line basis over the contract period. Warranty and R&M costs on these contracts are recognized as incurred.
Derivative Financial Instruments	As part of its risk management strategy, the Company enters into derivative contracts to hedge against the risks of interest rates, foreign currency rates and commodity prices. Certain derivative instruments designated as fair value hedges, cash flow hedges or net investment hedges are subject to hedge accounting. Derivative instruments that are not subject to hedge accounting are held as derivatives not designated as hedging instruments. The Company’s policies prohibit the use of derivatives for speculation or trading. At the inception of each hedge relationship, the Company documents its risk management objectives, procedures and accounting treatment. All of the Company’s interest-rate, commodity as well as certain foreign-exchange contracts are transacted under International Swaps and Derivatives Association (ISDA) master agreements. Each agreement permits the net settlement of amounts owed in the event of default and certain other termination events. For derivative financial instruments, the Company has elected not to offset derivative positions in the balance sheet with the same counterparty under the same agreements and is not required to post or receive collateral. Exposure limits and minimum credit ratings are used to minimize the risks of counterparty default. The Company’s maximum exposure to potential default of its derivative counterparties is limited to the asset position of its derivative portfolio. The asset position of the Company’s derivative portfolio was $65.8 at March 31, 2022. The Company assesses hedges at inception and on an ongoing basis to determine that the designated derivatives are highly effective in offsetting changes in fair values or cash flow of the hedged items. Hedge accounting is discontinued prospectively when the Company determines that a derivative financial instrument has ceased to be a highly effective hedge. Cash flows from derivative instruments are included in Operating activities in the Condensed Consolidated Statements of Cash Flows.
Fair Value Measurement Policy	Fair value represents 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 Level 1 – Valuations are based on quoted prices that the Company has the ability to obtain in actively traded markets for identical assets or liabilities. Since valuations are based on quoted prices that are readily and regularly available in an active market or exchange traded market, valuation of these instruments does not require a significant degree of judgment. Level 2 – Valuations are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3 – Valuations are based on model-based techniques for which some or all of the assumptions are obtained from indirect market information that is significant to the overall fair value measurement and which require a significant degree of management judgment. The Company uses the following methods and assumptions to measure fair value for assets and liabilities subject to recurring fair value measurements. Marketable Debt Securities: The Company’s marketable debt securities consist of municipal bonds, government obligations, investment-grade corporate obligations, commercial paper, asset-backed securities and term deposits. The fair value of U.S. government obligations is determined using the market approach and is based on quoted prices in active markets and are categorized as Level 1. The fair value of U.S. government agency obligations, non-U.S. government bonds, municipal bonds, corporate bonds, asset-backed securities, commercial paper and term deposits is determined using the market approach and is primarily based on matrix pricing as a practical expedient which does not rely exclusively on quoted prices for a specific security. Significant inputs used to determine fair value include interest rates, yield curves, credit rating of the security and other observable market information and are categorized as Level 2. Marketable Equity Securities: The Company’s equity securities are traded on active exchanges and are classified as Level 1. Derivative Financial Instruments: The Company’s derivative contracts consist of interest-rate swaps, cross currency swaps, foreign currency exchange and commodity contracts. These derivative contracts are traded over the counter, and their fair value is determined using industry standard valuation models, which are based on the income approach (i.e., discounted cash flows). The significant observable inputs into the valuation models include interest rates, yield curves, currency exchange rates, credit default swap spreads, forward rates and commodity prices and are categorized as Level 2.
