Accounting Policies [Abstract]
Significant Accounting Policies	A. SIGNIFICANT ACCOUNTING POLICIES Description of Operations: PACCAR Inc (the Company or PACCAR) is a multinational company operating in three principal segments: (1) the Truck segment includes the design and manufacture of high-quality, light-, medium- and heavy-duty commercial trucks; (2) the Parts segment includes the distribution of aftermarket parts for trucks and related commercial vehicles; and (3) the Financial Services segment (PFS) includes finance and leasing products and services provided to customers and dealers. PACCAR’s finance and leasing activities are principally related to PACCAR products and associated equipment. PACCAR’s sales and revenues are derived primarily from North America and Europe. The Company also operates in Australia and Brasil and sells trucks and parts to customers in Asia, Africa, the Middle East and South America. Principles of Consolidation: The consolidated financial statements include the accounts of the Company and its wholly owned domestic and foreign subsidiaries. All significant intercompany accounts and transactions are eliminated in consolidation. Use of Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Revenue Recognition: 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 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. 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 return rate over a nine-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 returned goods assets and the related return liabilities: At December 31, 2022 2021 ASSETS LIABILITIES ASSETS LIABILITIES Trucks: Other current assets $ 183.0 $ 255.7 Accounts payable, accrued expenses and other $ 185.0 $ 264.0 Other noncurrent assets, net 284.6 403.6 Other liabilities 298.9 423.9 $ 467.6 $ 483.9 $ 659.3 $ 687.9 Parts: Other current assets $ 77.7 $ 72.9 Accounts payable, accrued expenses and other $ 181.4 $ 172.1 $ 77.7 $ 181.4 $ 72.9 $ 172.1 The Company’s total commitment to acquire trucks at a guaranteed value for contracts accounted for as a sale was $971.9 at December 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 I, 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 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. Rental revenues for the years ended December 31, 2022, 2021 and 2020 were $788.8, $831.6 and $802.3, respectively. Depreciation and related leased unit operating expenses were $490.0, $665.7 and $776.5 for the years ended December 31, 2022, 2021 and 2020, respectively. 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 December 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 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. Cash and Cash Equivalents: Cash equivalents consist of liquid investments with a maturity at date of purchase of 90 days or less. 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. Equity Securities: Marketable equity securities are traded on active exchanges and are measured at fair value. The realized and unrealized gains (losses) are recognized in investment income. Receivables: Trade and Other Receivables: The Company’s trade and other receivables are recorded at cost, net of allowances. At December 31, 2022 and 2021, respectively, trade and other receivables included trade receivables from dealers and customers of $1,600.1 and $1,276.4 and other receivables of $319.7 and $298.7 relating primarily to value added tax receivables and supplier allowances and rebates. Finance and Other Receivables: Loans – Loans represent fixed or floating-rate loans to customers collateralized by the vehicles purchased and are recorded at amortized cost. Finance leases – Finance leases are sales-type finance leases, which lease equipment to retail customers and dealers. These leases are reported as the sum of minimum lease payments receivable and estimated residual value of the property subject to the contracts, reduced by unearned interest. Dealer wholesale financing – Dealer wholesale financing is floating-rate wholesale loans to PACCAR dealers for new and used trucks and are recorded at amortized cost. The loans are collateralized by the trucks being financed. Operating lease receivables and other – Operating lease receivables and other include monthly rentals due on operating leases, unamortized loan and lease origination costs, interest on loans and other amounts due within one year in the normal course of business. Allowance for Credit Losses: Truck, Parts and Other: The Company historically has not experienced significant losses or past due amounts on trade and other receivables in its Truck, Parts and Other businesses. Accounts are considered past due once the unpaid balance is over 30 days Financial Services: 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 three 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 December 31, 2022 and 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 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 and determines expected losses based on historical experience under similar market conditions. After determining the appropriate level of the allowance for credit losses, a provision for losses on finance receivables is charged to income as necessary to reflect management’s estimate of expected credit losses, net of recoveries, inherent in the portfolio. 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. 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. Cost of sales and revenues include shipping and handling costs incurred to deliver products to dealers and customers. Equipment on Operating Leases: The Company’s Financial Services segment leases equipment under operating leases to its customers. In addition, in the Truck segment, equipment sold to customers in Europe subject to an RVG by the Company may be accounted for as an operating lease. Equipment is recorded at cost and is depreciated on the straight-line basis to the lower of the estimated residual value or guarantee value. Lease and guarantee periods generally range from three to five years three to ten years Property, Plant and Equipment: Property, plant and equipment are stated at cost. Depreciation is computed by the straight-line method based on the estimated useful lives of various classes of assets. Certain production tooling and equipment are amortized on a unit of production basis. Long-lived Assets and Goodwill: The Company evaluates the carrying value of property, plant and equipment when events and circumstances warrant a review. Goodwill is tested for impairment at least on an annual basis. There were no significant impairment charges for the three years ended December 31, 2022. Goodwill was $104.1 and $110.6 at December 31, 2022 and 2021, respectively. The decrease in value was due to currency translation. Product Support Liabilities: Product support liabilities include estimated future payments related to product warranties and deferred revenues on optional extended warranties and R&M contracts. 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 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 hedged 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 $119.4 at December 31, 2022 The Company assesses hedges at inception and on an ongoing basis to determine 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 a derivative financial instrument has ceased to be a highly effective hedge. Cash flows from derivative instruments are included in operating activities in the Consolidated Statements of Cash Flows. Government Grants: The Company receives incentives from U.S. and non-U.S. governmental entities in the form of tax rebates or credits, grants, and loans. The benefit is generally recorded when all conditions attached to the incentive have been met and there is reasonable assurance of the receipt. Government incentives are recorded in accordance with their purpose as a reduction of expense, a reduction of the cost of the capital investment, or other income. The amount of government incentives recorded as a reduction of expenses and the amount of grants receivable for the years ended December 31, 2022, 2021 and 2020 are immaterial. Foreign Currency Translation: For most of the Company’s foreign subsidiaries, the local currency is the functional currency. All assets and liabilities are translated at year-end exchange rates and all income statement amounts are translated at the weighted average rates for the period. Translation adjustments are recorded in AOCI. The Company uses the U.S. dollar as the functional currency for all but one of its Mexican subsidiaries, which uses the local currency. For the U.S. functional currency entities in Mexico, inventories, cost of sales, property, plant and equipment and depreciation are remeasured at historical rates and resulting adjustments are included in net income. 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. On December 6, 2022, the Board of Directors declared a 50% common stock dividend payable on February 7, 2023, to stockholders of record on January 17, 2023, with fractional shares to be paid in cash. This resulted in the issuance of 174,035,361 additional shares and 411 fractional shares paid in cash. For all years presented, net income per share, weighted average number of common shares outstanding and cash dividends declared per share on common stock have been restated for the effect of the 50% dividend. 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 $140.5 to $10,539.0 at January 1, 2020. 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: Year Ended December 31, 2021 AS ORIGINALLY REPORTED EFFECT OF CHANGE AS ADJUSTED Truck, Parts and Other Cost of sales and revenues $ 19,110.1 $ (17.7 ) $ 19,092.4 Income Taxes 526.5 4.3 530.8 Net Income 1,852.1 13.4 1,865.5 Year Ended December 31, 2020 AS ORIGINALLY REPORTED EFFECT OF CHANGE AS ADJUSTED Truck, Parts and Other Cost of sales and revenues $ 15,076.4 $ (3.7 ) $ 15,072.7 Income Taxes 359.5 .9 360.4 Net Income 1,298.4 2.8 1,301.2 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 years ended December 31, 2021 and 2020. There was no impact on total net cash provided by operating activities.

In addition, repayment experience indicates that some loans, leases and other finance receivables will be paid prior to contract maturity, while others may be extended or modified. 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 five or more 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. Allowance for Credit Losses: 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 .1 (4.9 ) 12.0 (1.7 ) 5.5 Charge-offs (8.5 ) (.5 ) (9.0 ) Recoveries 7.5 2.2 9.7 Currency translation and other (2.8 ) .8 (2.0 ) Balance at December 31 $ 3.4 $ 2.2 $ 112.6 $ 2.9 $ 121.1 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 (1.3 ) .6 1.2 .5 Charge-offs (12.3 ) (2.5 ) (14.8 ) Recoveries 6.2 .3 6.5 Currency translation and other (.1 ) (2.1 ) (.1 ) (2.3 ) Balance at December 31 $ 3.3 $ 7.1 $ 104.4 $ 2.1 $ 116.9 * Operating lease and other trade receivables. 2020 DEALER CUSTOMER WHOLESALE RETAIL RETAIL OTHER* TOTAL Balance at January 1 ** $ 4.3 $ 9.2 $ 101.4 $ 3.7 $ 118.6 Provision for losses (1.0 ) (.8 ) 30.1 .5 28.8 Charge-offs (26.6 ) (1.4 ) (28.0 ) Recoveries 5.3 .4 5.7 Currency translation and other .1 1.8 1.9 Balance at December 31 $ 3.4 $ 8.4 $ 112.0 $ 3.2 $ 127.0 * Operating lease and other trade receivables. ** The beginning balance has been adjusted for the adoption of ASU 2016-13 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.

Repossessions: When the Company determines a customer is not likely to meet its contractual commitments, the Company repossesses the vehicles which serve as collateral for the loans, finance leases and equipment under operating leases. 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 December 31, 2022 and 2021 was $9.2 and $4.7, respectively. Proceeds from the sales of repossessed assets were $20.8, $45.3 and $85.6 for the years ended December 31, 2022, 2021 and 2020, respectively. These amounts are included in Proceeds from asset disposals in the Consolidated Statements of Cash Flows. Write-downs of repossessed equipment on operating leases are recorded as impairments and included in Financial Services Depreciation and other expenses on the Consolidated Statements of Income.

Leases	Dec. 31, 2022
Leases [Abstract]
Leases	K. LEASES The Company leases certain facilities and equipment. The Company determines whether an arrangement is or contains a lease at inception. The Company accounts for lease and non-lease components separately. The consideration in the contract is allocated to each separate lease and non-lease component of the contract generally based on the relative stand-alone price of the components. The lease component is accounted for in accordance with the lease standard and the non-lease component is accounted for in accordance with other standards. The Company uses its incremental borrowing rate in determining the present value of lease payments unless the rate implicit in the lease is available. The lease term may include options to extend or terminate the lease if it is reasonably certain that the Company will exercise that option. Leases that have a term of 12 months or less at the commencement date (“short-term leases”) are not included in the right-of-use assets and the lease liabilities. Lease expense for the short-term leases are recognized on a straight-line basis over the lease term. The components of lease expense were as follows: Year Ended December 31, 2022 2021 2020 Finance lease cost Amortization of right-of-use assets $ .9 $ .6 $ .9 Interest on lease liabilities .1 Operating lease cost 15.5 16.3 16.6 Short-term lease cost 2.4 3.0 .8 Variable lease cost 1.2 1.5 1.7 Total lease cost $ 20.0 $ 21.4 $ 20.1 For the years ended December 31, 2022, 2021 and 2020, total rental expenses for all leases were $20.0, $21.4 and $20.1, respectively.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	L. COMMITMENTS AND CONTINGENCIES At December 31, 2022, PACCAR had standby letters of credit and surety bonds totaling $32.5, from third-party financial institutions, in the normal course of business, which guarantee various insurance, financing and other activities. At December 31, 2022, PACCAR’s financial services companies, in the normal course of business, had outstanding commitments to fund new loan and lease transactions amounting to $1,363.3. The commitments generally expire in 90 days. The Company had other commitments, primarily to purchase production inventory, equipment and energy amounting to $83.2, $17.4, $4.9, $2.2, $.1 and $.5 for 2023, 2024, 2025, 2026, 2027 and beyond, respectively. The Company is involved in various stages of investigations and cleanup actions in different countries related to environmental matters. In certain of these matters, the Company has been designated as a “potentially responsible party” by domestic and foreign environmental agencies. The Company has accrued the estimated costs to investigate and complete cleanup actions where it is probable that the Company will incur such costs in the future. Expenditures related to environmental activities for the years ended December 31, 2022, 2021 and 2020 were $4.6, $4.0 and $1.9, respectively. While the timing and amount of the ultimate costs associated with future environmental cleanup cannot be determined, management expects that these matters will not have a significant effect on the Company’s consolidated financial position. 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 jurisdictions primarily in Europe against all major European truck manufacturers including the Company and certain subsidiaries. These claims and lawsuits include a number of collective proceedings, including a class action in the United Kingdom, alleging EC-related claims and seeking monetary 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 awaiting judgment in 2023 and others scheduled for trial in upcoming years. On February 7, 2023, the Competition Appeal Tribunal in the U.K. issued a judgment awarding the claimants monetary damages. The amount of the judgment is not material to the Company’s business, financial condition or results of operations. The Company is evaluating its options, including an appeal. 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. Considering the complexity of the claims and the different stages of the proceedings in a variety of jurisdictions, including the recent judgment in the U.K., the Company cannot at this time reasonably estimate a range of loss that may result. Adverse final decisions 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.

Compensation And Retirement Disclosure [Abstract]
Employee Benefits	M. EMPLOYEE BENEFITS Severance Costs: The Company incurred severance expense in 2022, 2021 and 2020 of $.6, $2.6 and $6.1 respectively Defined Benefit Pension Plans: The Company has several defined benefit pension plans, which cover a majority of its employees. The Company evaluates its actuarial assumptions on an annual basis and considers changes based upon market conditions and other factors. The expected return on plan assets is determined by using a market-related value of assets, which is calculated based on an average of the previous five years of asset gains and losses. Generally, accumulated unrecognized actuarial gains and losses are amortized using the 10% corridor approach. The corridor is defined as the greater of either 10% of the projected benefit obligation or the market-related value of plan assets. The amortization amount is the excess beyond the corridor divided by the average remaining estimated service life of participants on a straight-line basis. The Company funds its pensions in accordance with applicable employee benefit and tax laws. The Company contributed $39.1 to its pension plans in 2022 and $25.1 in 2021. The Company expects to contribute in the range of $25 to $75 to its pension plans in 2023, of which $20.5 is estimated to satisfy minimum funding requirements. Annual benefits expected to be paid beginning January 1, 2023 are $120.3, $120.3, $123.5, $129.3, $131.9 and a total of $783.0 for the five years thereafter. Plan assets are invested in global equity and debt securities through professional investment managers with the objective to achieve targeted risk adjusted returns and maintain liquidity sufficient to fund current benefit payments. Typically, each defined benefit plan has an investment policy that includes a target for asset mix, including maximum and minimum ranges for allocation percentages by investment category. The actual allocation of assets may vary at times based upon rebalancing policies and other factors. The Company periodically assesses the target asset mix by evaluating external sources of information regarding the long-term historical return, volatilities and expected future returns for each investment category. In addition, the long-term rates of return assumptions for pension accounting are reviewed annually to ensure they are appropriate. Target asset mix and forecast long-term returns by asset category are considered in determining the assumed long-term rates of return, although historical returns realized are given some consideration. The fair value of mutual funds, common stocks and U.S. treasuries is determined using the market approach and is based on the quoted prices in active markets. These securities are categorized as Level 1. The fair value of debt securities is determined using the market approach and is based on the quoted market prices of the securities or other observable inputs. These securities are categorized as Level 2. The fair value of commingled and pooled trust funds is determined using the market approach and is based on the unadjusted net asset value (NAV) per unit as determined by the sponsor of the fund based on the fair values of underlying investments. These assets are collective investment trusts and pooled funds, and substantially all of these investments have no redemption restrictions or unfunded commitments. Securities measured at NAV per unit as a practical expedient are not classified in the fair value hierarchy. The following information details the allocation of plan assets by investment type.

The accumulated benefit obligation for all pension plans of the Company was $2,265.1 and $3,276.0 at December 31, 2022 and 2021, respectively. Information for all plans with an accumulated benefit obligation in excess of plan assets is as follows: At December 31, 2022 2021 Projected benefit obligation $ 126.7 $ 171.5 Accumulated benefit obligation 113.7 153.3 Fair value of plan assets 6.8 13.3 The components of pension expense are as follows: Year Ended December 31, 2022 2021 2020 Service cost $ 148.5 $ 148.4 $ 130.4 Interest on projected benefit obligation 84.9 65.3 83.0 Expected return on assets (215.1 ) (203.3 ) (190.6 ) Amortization of prior service costs .7 .8 1.5 Recognized actuarial loss 28.9 58.7 44.2 Settlement loss 11.6 Net pension expense $ 47.9 $ 69.9 $ 80.1 The components of net pension expense other than service cost are included in Interest and other (income), net on the Consolidated Statements of Income. Multi-employer Plans: The Company participates in multi-employer plans in the U.S. and Europe. These are typically under collective bargaining agreements and cover its union-represented employees. The Company’s participation in the following multi-employer plans for the years ended December 31 are as follows: PENSION COMPANY CONTRIBUTIONS PENSION PLAN EIN NUMBER SURCHARGE 2022 2021 2020 Metal and Electrical Engineering Industry Pension 135668 Yes $ 37.1 $ 38.1 $ 33.9 Western Metal Industry Pension Plan 91-6033499 001 Yes 4.0 4.0 3.0 Other plans 1.0 1.1 .9 $ 42.1 $ 43.2 $ 37.8 The Company contributions shown in the table above approximate the multi-employer pension expense for each of the years ended December 31, 2022, 2021 and 2020, respectively. Metal and Electrical Engineering Industry Pension Fund is a multi-employer union plan incorporating all DAF employees in the Netherlands and is covered by a collective bargaining agreement that will expire on May 31, 2024. The Company’s contributions were less than 5% of the total contributions to the plan for the last two reporting periods ending December 2022. The plan is required by law (the Netherlands Pension Act) to have a minimum coverage ratio in excess of 104.3% and a policy coverage ratio in excess of 118.1% (weighted coverage ratio of the last 12 months). Because the policy coverage ratio of 110.4% at December 31, 2022 is below the required threshold, a funding improvement plan remains in place. Based on the funding improvement plan, the required coverage of 118.1% should be reached by the end of 2026. The funding improvement plan includes a possible reduction in pension benefits and delays in future benefit increases. The Western Metal Industry Pension Plan is located in the U.S. and is covered by a collective bargaining agreement that will expire on November 2, 2025. In accordance with the U.S. Pension Protection Act of 2006, the plan continued to be certified as critical (red) status as of December 31, 2022, and a funding improvement plan has been implemented requiring additional contributions through 2022 as long as the plan remains in critical status. Contributions by the Company were 25% and 20% of the total contributions to the plan for the years ended December 31, 2022 and 2021, respectively. Other plans are principally located in the U.S. and the Company’s contributions to these plans for the years ended December 31, 2022 and 2021 were less than 5% of each plan’s total contributions. As of December 31, 2022, one of the other plans was under a funding rehabilitation plan requiring an increase to the mandated employer surcharge from 5% to 10%, which will be applicable for each succeeding year in which the plan remains in a critical status. There were no significant changes for the multi-employer plans in the periods presented that affected comparability between periods. Defined Contribution Plans: The Company maintains several defined contribution benefit plans whereby it contributes designated amounts on behalf of participant employees. The largest plan is for U.S. salaried employees where the Company matches a percentage of employee contributions up to an annual limit. The match was 5% of eligible pay in 2022, 2021 and 2020. Other plans are located in Australia, the Netherlands, Canada, United Kingdom and Germany. Expenses for these plans were $56.3, $50.0 and $42.5 in 2022, 2021 and 2020, respectively

Income Tax Disclosure [Abstract]
Income Taxes	N. INCOME TAXES The Company’s tax rate is based on income and statutory tax rates in the various jurisdictions in which the Company operates. Tax law requires certain items to be included in the Company’s tax returns at different times than the items reflected in the Company’s financial statements. As a result, the Company’s annual tax rate reflected in its financial statements is different than that reported in its tax returns. Some of these differences are permanent, such as expenses that are not deductible in the Company’s tax return, and some differences reverse over time, such as depreciation expense. These temporary differences create deferred tax assets and liabilities. The Company establishes valuation allowances for its deferred tax assets if, based on the available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. The components of the Company’s income before income taxes include the following: Year Ended December 31, 2022 2021 2020 Domestic $ 2,322.9 $ 1,391.4 $ 1,126.5 Foreign 1,525.8 1,004.9 535.1 $ 3,848.7 $ 2,396.3 $ 1,661.6 The components of the Company’s provision for income taxes include the following: Year Ended December 31, 2022 2021 2020 Current provision: Federal $ 567.0 $ 410.0 $ 182.5 State 143.1 85.9 44.9 Foreign 335.0 243.5 132.6 1,045.1 739.4 360.0 Deferred (benefit) provision: Federal (173.2 ) (176.0 ) (10.5 ) State (42.0 ) (29.6 ) 1.9 Foreign 7.2 (3.0 ) 9.0 (208.0 ) (208.6 ) .4 $ 837.1 $ 530.8 $ 360.4 Tax benefits recognized for net operating loss carryforwards were $3.9, $5.1 and $17.8 for the years ended 2022, 2021 and 2020, respectively. A reconciliation of the statutory U.S. federal tax rate to the effective income tax rate is as follows: 2022 2021 2020 Statutory rate 21.0 % 21.0 % 21.0 % Effect of: State 2.1 2.0 2.3 Research and development tax credit (1.0 ) (1.2 ) (1.4 ) Tax on foreign earnings .5 1.1 .8 Other, net (.8 ) (.7 ) (1.0 ) 21.8 % 22.2 % 21.7 % Based on the Company’s current operations, the Company does not expect that the repatriation of future foreign earnings will be subject to significant income tax as a result of the U.S. modified territorial system. At December 31, 2022, the Company had net operating loss carryforwards of $404.6, of which $352.5 related to foreign subsidiaries and $52.1 related to states in the U.S. The related deferred tax asset was $119.2, for which a $102.3 valuation allowance has been provided. The carryforward periods range from four years to indefinite, subject to certain limitations under applicable laws. The future tax benefits of net operating loss carryforwards are evaluated on a regular basis, including a review of historical and projected operating results. The tax effects of temporary differences representing deferred tax assets and liabilities are as follows: At December 31, 2022 2021 Assets: Accrued liabilities $ 252.2 $ 210.9 R&D expense capitalization 153.6 Net operating loss and tax credit carryforwards 128.0 124.9 Inventory adjustments 59.5 Allowance for losses on receivables 43.8 36.5 Unrealized investment loss 16.5 .8 Other 79.1 71.1 732.7 444.2 Valuation allowance (116.2 ) (109.3 ) 616.5 334.9 Liabilities: Financial Services leasing depreciation (558.9 ) (547.1 ) Depreciation and amortization (227.3 ) (166.8 ) Postretirement benefit plans (120.5 ) (86.5 ) Inventory adjustments (11.5 ) Other (59.2 ) (33.2 ) (965.9 ) (845.1 ) Net deferred tax liability $ (349.4 ) $ (510.2 ) The balance sheet classifications of the Company’s deferred tax assets and liabilities are as follows: At December 31, 2022 2021 Truck, Parts and Other: Other noncurrent assets, net $ 199.0 $ 51.5 Other liabilities (75.5 ) (91.5 ) Financial Services: Other assets 51.0 48.4 Deferred taxes and other liabilities (523.9 ) (518.6 ) Net deferred tax liability $ (349.4 ) $ (510.2 ) Cash paid for income taxes was $932.1, $761.1 and $374.0 in 2022, 2021 and 2020, respectively. A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows: 2022 2021 2020 Balance at January 1 $ 26.0 $ 24.5 $ 30.7 Additions for tax positions related to the current year 7.4 6.1 5.5 Additions for tax positions related to prior years 1.8 .8 .3 Reductions for tax positions related to prior years (1.6 ) (4.2 ) Lapse of statute of limitations (5.8 ) (5.4 ) (7.8 ) Balance at December 31 $ 27.8 $ 26.0 $ 24.5 The Company had $27.8, $26.0 and $24.5 of unrecognized tax benefits, of which $27.8, $25.3 and $23.2 would impact the effective tax rate, if recognized, as of December 31, 2022, 2021 and 2020, respectively. The Company recognized $.1, $(.4) and $(.7) of expense (income) related to interest in 2022, 2021 and 2020, respectively. Accrued interest expense and penalties were $.9, $.8 and $1.2 as of December 31, 2022, 2021 and 2020, respectively. Interest and penalties are classified as income taxes in the Consolidated Statements of Income. The Company believes it is reasonably possible that approximately $5.7 of unrecognized tax benefits, resulting primarily from research and development tax credits, will be resolved within the next 12 months. As of December 31, 2022, the United States Internal Revenue Service has completed examinations of the Company’s tax returns for all years through 2014. The Company’s tax returns for other major jurisdictions remain subject to examination for the years ranging from 2012 through 2022.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	P. DERIVATIVE FINANCIAL INSTRUMENTS As part of its risk management strategy, the Company enters into derivative contracts to hedge against the risk of interest rates, foreign currency rates, and commodity prices. 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 December 31, 2022, the notional amount of the Company’s interest-rate contracts was $3,023.1. Notional maturities for all interest-rate contracts are $679.3 for 2023, $604.4 for 2024, $1,039.3 for 2025, $409.1 for 2026, $176.1 for 2027 and $114.9 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 December 31, 2022 , the notional amount of the outstanding foreign-exchange contracts was $ . Foreign -exchange contracts typically mature within one year . 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 December 31, 2022, the notional amount of the outstanding commodity contracts was $32.3. 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: At December 31, 2022 2021 ASSETS LIABILITIES ASSETS LIABILITIES Derivatives designated under hedge accounting: Interest-rate contracts: Financial Services: Other assets $ 58.0 $ 30.8 Deferred taxes and other liabilities $ 82.6 $ 54.4 Foreign-exchange contracts: Truck, Parts and Other: Other current assets 57.3 25.3 Accounts payable, accrued expenses and other 9.5 15.8 Financial Services: Other current assets 1.6 2.5 Deferred taxes and other liabilities 5.1 .1 Commodity contracts: Truck, Parts and Other: Other current assets 1.5 Accounts payable, accrued expenses and other .6 16.9 $ 118.4 $ 97.8 $ 58.6 $ 87.2 Derivatives not designated as hedging instruments: Foreign-exchange contracts: Truck, Parts and Other: Other current assets $ 1.0 $ 1.0 Accounts payable, accrued expenses and other $ .1 $ 1.1 Financial Services: Other assets .1 Deferred taxes and other liabilities .1 .2 Commodity contracts: Truck, Parts and Other: Accounts payable, accrued expenses and other .2 $ 1.0 $ .4 $ 1.1 $ 1.3 Gross amounts recognized in Balance Sheet $ 119.4 $ 98.2 $ 59.7 $ 88.5 Less amounts not offset in financial instruments: Truck, Parts and Other: Foreign-exchange contracts $ (.1 ) $ (.1 ) $ (2.7 ) $ (2.7 ) Commodity contracts (.5 ) (.5 ) Financial Services: Foreign-exchange contracts (1.8 ) (1.8 ) (.2 ) (.2 ) Interest-rate contracts (21.5 ) (21.5 ) (12.8 ) (12.8 ) Pro forma net amount $ 95.5 $ 74.3 $ 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: Year Ended December 31, 2022 2021 2020 INTEREST- FOREIGN- INTEREST- FOREIGN- INTEREST- FOREIGN- RATE EXCHANGE RATE EXCHANGE RATE EXCHANGE Truck, Parts and Other: Net sales and revenues Cash flow hedges $ 19.3 $ 16.6 $ (4.0 ) Cost of sales and revenues Cash flow hedges (15.3 ) (1.0 ) 1.7 Derivatives not designated as hedging instruments (1.7 ) 8.9 .7 Interest and other (income), net Cash flow hedges (1.4 ) (.1 ) (4.6 ) Net investment hedges (5.8 ) (3.2 ) (5.6 ) Derivatives not designated as hedging instruments .8 1.9 2.3 $ (4.1 ) $ 23.1 $ (9.5 ) Financial Services: Interest and other borrowing expenses Cash flow hedges $ 6.1 $ 7.3 $ (49.8 ) $ 94.5 Fair value hedges 1.0 .4 1.1 Derivatives not designated as hedging instruments (8.1 ) $ (.5 ) $ 9.4 Selling, general and administrative Derivatives not designated as hedging instruments .8 $ 7.1 $ (.8 ) $ (49.4 ) $ (.5 ) $ 95.6 $ 10.2 Total $ 7.1 $ (4.9 ) $ (49.4 ) $ 22.6 $ 95.6 $ .7 The Company began commodity hedging in 2021. The loss from commodity contracts recorded in cost of sales and revenue was $31.8 and $.6 for the year ended 2022 and 2021, respectively. 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: At December 31, 2022 2021 Financial Services Term notes: Carrying amount of hedged liabilities $ 319.8 $ 472.0 Cumulative basis adjustment included in the carrying amount 27.7 8.7 The above table excludes the cumulative basis adjustments on discontinued hedge relationships of $7.1 and $.1 as of December 31, 2022 and 2021, respectively. Cash Flow Hedges Substantially all of the Company’s interest-rate contracts and some foreign-exchange 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 9.9 years. The following table presents the pre-tax effects of gain (loss) on cash flow hedges recognized in other comprehensive income (loss) (OCI): Year Ended December 31, 2022 2021 2020 INTEREST- FOREIGN- INTEREST- FOREIGN- INTEREST- FOREIGN- RATE EXCHANGE RATE EXCHANGE RATE EXCHANGE Gain (loss) recognized in OCI: Truck, Parts and Other $ 41.2 $ (18.5 ) $ 2.8 Financial Services $ 19.1 (25.5 ) $ 83.2 (1.9 ) $ (107.3 ) (.8 ) $ 19.1 $ 15.7 $ 83.2 $ (20.4 ) $ (107.3 ) $ 2.0 The pre-tax effects of loss on commodity hedges recognized in other comprehensive income (loss) (OCI) for Truck, Parts and Other was $17.1 and $8.6 in 2022 and 2021, respectively. The amount of gain recorded in AOCI at December 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 $18.3, 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 nil 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). The notional amount of the outstanding net investment hedge was $347.0 and $360.7 at December 31, 2022 and 2021, respectively.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Q. 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 measurement date. Inputs to valuation techniques used to measure fair value are either observable or unobservable. These inputs have been categorized into the fair value hierarchy described below. 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. There were no transfer of assets or liabilities between Level 1 and Level 2 of the fair value hierarchy during the year ended December 31, 2022. The Company’s policy is to recognize transfers between levels at the end of the reporting period. 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 December 31, 2022 LEVEL 1 LEVEL 2 TOTAL Assets: Marketable debt securities U.S. tax-exempt securities $ 445.1 $ 445.1 U.S. taxable municipal / non-U.S. provincial bonds 180.8 180.8 U.S. corporate securities 251.0 251.0 U.S. government and agency securities $ 115.0 115.0 Non-U.S. corporate securities 450.0 450.0 Non-U.S. government securities 76.4 76.4 Other debt securities 94.7 94.7 Total marketable debt securities $ 115.0 $ 1,498.0 $ 1,613.0 Marketable equity securities $ 1.2 $ 1.2 Total marketable securities $ 116.2 $ 1,498.0 $ 1,614.2 Derivatives Cross currency swaps $ 49.1 $ 49.1 Interest-rate swaps 8.9 8.9 Foreign-exchange contracts 59.9 59.9 Commodity swaps 1.5 1.5 Total derivative assets $ 119.4 $ 119.4 Liabilities: Derivatives Cross currency swaps $ 52.0 $ 52.0 Interest-rate swaps 30.6 30.6 Foreign-exchange contracts 14.8 14.8 Commodity contracts .8 .8 Total derivative liabilities $ 98.2 $ 98.2 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 / non-U.S. 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: At December 31, 2022 2021 CARRYING FAIR CARRYING FAIR AMOUNT VALUE AMOUNT VALUE Assets: Financial Services fixed rate loans $ 6,859.1 $ 6,582.0 $ 6,011.7 $ 6,018.2 Liabilities: Financial Services fixed rate debt 8,070.5 7,715.9 6,905.7 6,935.1

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock Compensation Plans	R. STOCK COMPENSATION PLANS PACCAR has certain plans under which officers and key employees may be granted options to purchase shares of the Company’s authorized but unissued common stock under plans approved by stockholders. Non‑employee directors and certain officers may be granted restricted shares of the Company’s common stock under plans approved by stockholders. Options outstanding under these plans were granted with exercise prices equal to the fair market value of the Company’s common stock at the date of grant. Options expire no later than ten years from the grant date and generally vest after three years. Restricted stock awards generally vest over three years or earlier upon meeting certain age and service requirements. The Company recognizes compensation cost on these options and restricted stock awards on a straight-line basis over the requisite period the employee is required to render service less estimated forfeitures based on historical experience. The plans contain antidilution provisions. Consequently, the following data has been restated to reflect the Company’s 50% stock dividend in February 2023. The maximum number of shares of the Company’s common stock authorized for issuance under these plans is 70.0 million shares, and as of December 31, 2022, the maximum number of shares available for future grants was 16.0 million. The assumptions used in determining the fair value of the option awards for each of the grant years are as follows: 2022 2021 2020 Risk-free interest rate 1.86 % .71 % 1.54 % Expected volatility 26 % 26 % 23 % Expected dividend yield 4.3 % 3.6 % 4.1 % Expected term 6 years 6 years 6 years Weighted average grant date fair value of options per share $ 9.70 $ 9.48 $ 6.68 The estimated fair value of each option award is determined on the date of grant using the Black-Scholes-Merton option pricing model that uses assumptions noted in the table above. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. Expected volatility is based on historical volatility. The dividend yield is based on an estimated future dividend yield using projected net income for the next five years, implied dividends and Company stock price. The expected term is based on the period of time that options granted are expected to be outstanding based on historical experience. The fair value of options granted was $8.3, $8.1 and $6.4 for the years ended December 31, 2022, 2021 and 2020, respectively. The fair value of options vested was $5.6 during the years ended December 31, 2022 and 2021, and was $5.0 during the year ended December 31, 2020.

Segment Reporting [Abstract]
Segment and Related Information	S. SEGMENT AND RELATED 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. Geographic revenues from external customers are presented based on the country of the customer. The accounting policies of the reportable segments are the same as those applied in the consolidated financial statements as described in Note A. 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 marketing of used trucks, including those units sold by the Truck segment subject to an RVG, is performed by the Financial Services segment. 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 expense s not attributable to a reportable segment. Other also includes non-service cost components of pension expense and a portion of corporate expenses. Intercompany interest income (expense) on cash advances with the financial services companies is included in Other and was $(1.9) , $ .4 and $1.4 for 202 2 , 20 2 1 and 20 20 , respectively.

Accounting Policies [Abstract]
Description of Operations	Description of Operations: PACCAR Inc (the Company or PACCAR) is a multinational company operating in three principal segments: (1) the Truck segment includes the design and manufacture of high-quality, light-, medium- and heavy-duty commercial trucks; (2) the Parts segment includes the distribution of aftermarket parts for trucks and related commercial vehicles; and (3) the Financial Services segment (PFS) includes finance and leasing products and services provided to customers and dealers. PACCAR’s finance and leasing activities are principally related to PACCAR products and associated equipment. PACCAR’s sales and revenues are derived primarily from North America and Europe. The Company also operates in Australia and Brasil and sells trucks and parts to customers in Asia, Africa, the Middle East and South America.
Principles of Consolidation	Principles of Consolidation: The consolidated financial statements include the accounts of the Company and its wholly owned domestic and foreign subsidiaries. All significant intercompany accounts and transactions are eliminated in consolidation.
Use of Estimates	Use of Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
Revenue Recognition	Revenue Recognition: 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 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. 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 return rate over a nine-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 returned goods assets and the related return liabilities: At December 31, 2022 2021 ASSETS LIABILITIES ASSETS LIABILITIES Trucks: Other current assets $ 183.0 $ 255.7 Accounts payable, accrued expenses and other $ 185.0 $ 264.0 Other noncurrent assets, net 284.6 403.6 Other liabilities 298.9 423.9 $ 467.6 $ 483.9 $ 659.3 $ 687.9 Parts: Other current assets $ 77.7 $ 72.9 Accounts payable, accrued expenses and other $ 181.4 $ 172.1 $ 77.7 $ 181.4 $ 72.9 $ 172.1 The Company’s total commitment to acquire trucks at a guaranteed value for contracts accounted for as a sale was $971.9 at December 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 I, 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 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. Rental revenues for the years ended December 31, 2022, 2021 and 2020 were $788.8, $831.6 and $802.3, respectively. Depreciation and related leased unit operating expenses were $490.0, $665.7 and $776.5 for the years ended December 31, 2022, 2021 and 2020, respectively. 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 December 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 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.
Cash and Cash Equivalents	Cash and Cash Equivalents: Cash equivalents consist of liquid investments with a maturity at date of purchase of 90 days or less.
Investments in Marketable Securities	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. Equity Securities: Marketable equity securities are traded on active exchanges and are measured at fair value. The realized and unrealized gains (losses) are recognized in investment income.
Receivables	Receivables: Trade and Other Receivables: The Company’s trade and other receivables are recorded at cost, net of allowances. At December 31, 2022 and 2021, respectively, trade and other receivables included trade receivables from dealers and customers of $1,600.1 and $1,276.4 and other receivables of $319.7 and $298.7 relating primarily to value added tax receivables and supplier allowances and rebates. Finance and Other Receivables: Loans – Loans represent fixed or floating-rate loans to customers collateralized by the vehicles purchased and are recorded at amortized cost. Finance leases – Finance leases are sales-type finance leases, which lease equipment to retail customers and dealers. These leases are reported as the sum of minimum lease payments receivable and estimated residual value of the property subject to the contracts, reduced by unearned interest. Dealer wholesale financing – Dealer wholesale financing is floating-rate wholesale loans to PACCAR dealers for new and used trucks and are recorded at amortized cost. The loans are collateralized by the trucks being financed. Operating lease receivables and other – Operating lease receivables and other include monthly rentals due on operating leases, unamortized loan and lease origination costs, interest on loans and other amounts due within one year in the normal course of business.
Allowance for Credit Losses	Allowance for Credit Losses: Truck, Parts and Other: The Company historically has not experienced significant losses or past due amounts on trade and other receivables in its Truck, Parts and Other businesses. Accounts are considered past due once the unpaid balance is over 30 days Financial Services: 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 three 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 December 31, 2022 and 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 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 and determines expected losses based on historical experience under similar market conditions. After determining the appropriate level of the allowance for credit losses, a provision for losses on finance receivables is charged to income as necessary to reflect management’s estimate of expected credit losses, net of recoveries, inherent in the portfolio. 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.
Inventories	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. Cost of sales and revenues include shipping and handling costs incurred to deliver products to dealers and customers.
Equipment on Operating Leases	Equipment on Operating Leases: The Company’s Financial Services segment leases equipment under operating leases to its customers. In addition, in the Truck segment, equipment sold to customers in Europe subject to an RVG by the Company may be accounted for as an operating lease. Equipment is recorded at cost and is depreciated on the straight-line basis to the lower of the estimated residual value or guarantee value. Lease and guarantee periods generally range from three to five years three to ten years
Property, Plant and Equipment	Property, Plant and Equipment: Property, plant and equipment are stated at cost. Depreciation is computed by the straight-line method based on the estimated useful lives of various classes of assets. Certain production tooling and equipment are amortized on a unit of production basis.
Long-lived Assets and Goodwill	Long-lived Assets and Goodwill: The Company evaluates the carrying value of property, plant and equipment when events and circumstances warrant a review. Goodwill is tested for impairment at least on an annual basis. There were no significant impairment charges for the three years ended December 31, 2022. Goodwill was $104.1 and $110.6 at December 31, 2022 and 2021, respectively. The decrease in value was due to currency translation.
Product Support Liabilities	Product Support Liabilities: Product support liabilities include estimated future payments related to product warranties and deferred revenues on optional extended warranties and R&M contracts. 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 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	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 hedged 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 $119.4 at December 31, 2022 The Company assesses hedges at inception and on an ongoing basis to determine 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 a derivative financial instrument has ceased to be a highly effective hedge. Cash flows from derivative instruments are included in operating activities in the Consolidated Statements of Cash Flows. As part of its risk management strategy, the Company enters into derivative contracts to hedge against the risk of interest rates, foreign currency rates, and commodity prices.
Government Grants	Government Grants: The Company receives incentives from U.S. and non-U.S. governmental entities in the form of tax rebates or credits, grants, and loans. The benefit is generally recorded when all conditions attached to the incentive have been met and there is reasonable assurance of the receipt. Government incentives are recorded in accordance with their purpose as a reduction of expense, a reduction of the cost of the capital investment, or other income. The amount of government incentives recorded as a reduction of expenses and the amount of grants receivable for the years ended December 31, 2022, 2021 and 2020 are immaterial.
Foreign Currency Translation	Foreign Currency Translation: For most of the Company’s foreign subsidiaries, the local currency is the functional currency. All assets and liabilities are translated at year-end exchange rates and all income statement amounts are translated at the weighted average rates for the period. Translation adjustments are recorded in AOCI. The Company uses the U.S. dollar as the functional currency for all but one of its Mexican subsidiaries, which uses the local currency. For the U.S. functional currency entities in Mexico, inventories, cost of sales, property, plant and equipment and depreciation are remeasured at historical rates and resulting adjustments are included in net income.
Earnings per Share	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. On December 6, 2022, the Board of Directors declared a 50% common stock dividend payable on February 7, 2023, to stockholders of record on January 17, 2023, with fractional shares to be paid in cash. This resulted in the issuance of 174,035,361 additional shares and 411 fractional shares paid in cash. For all years presented, net income per share, weighted average number of common shares outstanding and cash dividends declared per share on common stock have been restated for the effect of the 50% dividend.
New Accounting Pronouncements	New Accounting Pronouncements The Company adopted the following standards on January 1, 2022, which had no material impact on the Company’s consolidated financial statements. STANDARD DESCRIPTION 2021-05 Leases (Topic 842) – Lessors – Certain Leases with Variable Lease Payments 2021-10 Government Assistance (Topic 832) - Disclosures by Business Entities about Government Assistance The Financial Accounting Standards Board (FASB) also issued the following standards, which are not expected to have a material impact on the Company’s consolidated financial statements. STANDARD DESCRIPTION EFFECTIVE DATE 2022-02* Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures January 1, 2023 2022-03* Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions January 1, 2024 * The Company will adopt on the effective date.
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 measurement date. Inputs to valuation techniques used to measure fair value are either observable or unobservable. These inputs have been categorized into the fair value hierarchy described below. 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. There were no transfer of assets or liabilities between Level 1 and Level 2 of the fair value hierarchy during the year ended December 31, 2022. The Company’s policy is to recognize transfers between levels at the end of the reporting period. 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.
