Notes to Consolidated Financial Statements (Unaudited) (Millions, Except Share Amounts)

NOTE A - Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10‑Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. For further information, refer to the consolidated financial statements and footnotes included in PACCAR Inc’s (PACCAR or the Company) Annual Report on Form 10‑K for the year ended December 31, 2023.

Earnings per Share: Basic earnings per common share are computed by dividing earnings by the weighted average number of common shares outstanding, plus the effect of any participating securities. Diluted earnings per common share are computed assuming that all potentially dilutive securities are converted into common shares under the treasury stock method.

The dilutive and antidilutive options are shown separately in the table below:

Three Months Ended March 31,	2024		2023
Additional shares		1,439,200		958,300
Antidilutive options		671,000		889,000

New Accounting Pronouncements: In November 2023, the Financial Accounting Standards Board (FASB) issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amendments in this ASU improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This ASU is effective for annual periods beginning after December 15, 2023, and interim periods within annual periods beginning after December 15, 2024. Early adoption is permitted. The amendments in this ASU should be applied retrospectively to all prior periods presented. The implementation of this ASU will result in additional disclosures and will not have an impact on the Company’s consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments in this ASU require entities to disclose certain, specific categories within the rate reconciliation and enhance disclosures regarding income taxes paid and income tax expense. This ASU is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The amendments in this ASU should be applied on a prospective basis; however, retrospective application is permitted. The implementation of this ASU will result in additional disclosures and will not have an impact on the Company’s consolidated financial statements.

The Company adopted ASU 2022-03, Fair Value Measurement (Topic 820)—Fair Value Measurement of Equity Securities Subject to Contractual Sale Restriction on January 1, 2024, which had no material impact on the Company’s consolidated financial statements.

NOTE B – Sales and Revenues

Truck, Parts and Other

The Company enters into sales contracts with customers associated with purchases of the Company’s products and services including trucks, parts, product support, and other related services. Generally, the Company recognizes revenue for the amount of consideration it will receive for delivering a product or service to a customer. Revenue is recognized when the customer obtains control of the product or receives benefits of the service. The Company excludes sales taxes, value added taxes and other related taxes assessed by government agencies from revenue. There are no significant financing components included in product or services revenue since generally customers pay shortly after the products or services are transferred. In the Truck and Parts segment, when the Company grants extended payment terms on selected receivables and charges interest, interest income is recognized when earned.

Notes to Consolidated Financial Statements (Unaudited) (Millions, Except Share Amounts)

The following table disaggregates Truck, Parts and Other revenues by major sources:

Three Months Ended March 31,	2024		2023
Truck
Truck sales	$	6,304.7	$	6,206.0
Revenues from extended warranties, operating leases and other		236.3		207.8
		6,541.0		6,413.8
Parts
Parts sales		1,625.6		1,574.2
Revenues from dealer services and other		50.3		48.8
		1,675.9		1,623.0
Winch sales and other		18.1		13.3
Truck, Parts and Other sales and revenues	$	8,235.0	$	8,050.1

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.

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:

	March 31, 2024				December 31, 2023
	ASSETS		LIABILITIES		ASSETS		LIABILITIES
Trucks
Other current assets	$	132.7			$	147.3
Accounts payable, accrued expenses and other			$	135.7			$	149.5
Other noncurrent assets, net		171.6				186.7
Other liabilities				180.2				196.4
	$	304.3	$	315.9	$	334.0	$	345.9
Parts
Other current assets	$	92.3			$	86.8
Accounts payable, accrued expenses and other			$	226.4			$	216.3
	$	92.3	$	226.4	$	86.8	$	216.3

The Company’s total commitment to acquire trucks at a guaranteed value for contracts accounted for as a sale was $678.5 at March 31, 2024.

Notes to Consolidated Financial Statements (Unaudited) (Millions, Except Share Amounts)

Revenues from extended warranties, operating leases and other include optional extended warranty and repair and maintenance (R&M) service contracts which can be purchased for periods generally ranging up to five years. The Company defers revenue based on stand-alone observable selling prices when it receives payments in advance and generally recognizes the revenue on a straight-line basis over the warranty or R&M contract periods. See Note F, Product Support Liabilities, in the Notes to the Consolidated Financial Statements for further information. Also included are truck sales with an RVG accounted for as an operating lease. A liability is created for the residual value obligation with the remainder of the proceeds recorded as deferred revenue. The deferred revenue is recognized on a straight-line basis over the guarantee period, which typically ranges from three to five years. Deferred revenue related to trucks sold with an RVG was $19.1 at March 31, 2024. The Company expects to recognize approximately $11.4 of the remaining deferred revenue in 2024, $5.0 in 2025, $1.8 in 2026, $.8 in 2027 and $.1 in 2028. Total operating lease revenue from truck sales with RVGs was $9.8 and $12.8 for the three months ended March 31, 2024 and 2023, respectively. The Company’s total commitment to acquire trucks at a guaranteed value for contracts accounted for as a lease was $108.1 at March 31, 2024.

Revenue from winch sales and other is primarily derived from the industrial winch business. Winch sales are recognized when the product is transferred to a customer, which generally occurs upon shipment. Also within this category are other revenues not attributable to a reportable segment.

Financial Services

The Company’s Financial Services segment products include loans to customers collateralized by the vehicles being financed, finance leases for retail customers and dealers, dealer wholesale financing which includes floating-rate wholesale loans to PACCAR dealers for new and used trucks, and operating leases which include rentals on Company owned equipment. Interest income from finance and other receivables is recognized using the interest method. Certain loan origination costs are deferred and amortized to interest income over the expected life of the contracts using the straight-line method which approximates the interest method.

Operating lease rental revenue is recognized on a straight-line basis over the term of the lease. Customer contracts may include additional services such as excess mileage, repair and maintenance and other services on which revenue is recognized when earned. The Company’s full-service lease arrangements bundle these additional services. Rents for full-service lease contracts are allocated between lease and non-lease components based on the relative stand-alone price of each component. Taxes, such as sales and use and value added, which are collected by the Company from a customer, are excluded from the measurement of lease income and expenses.

Recognition of interest income and rental revenue is suspended (put on non-accrual status) when the receivable becomes more than 90 days past the contractual due date or earlier if some other event causes the Company to determine that collection is not probable. Accordingly, no finance receivables more than 90 days past due were accruing interest at March 31, 2024 or December 31, 2023. Recognition is resumed if the receivable becomes current by the payment of all amounts due under the terms of the existing contract and collection of remaining amounts is considered probable (if not contractually modified) or if the customer makes scheduled payments for three months and collection of remaining amounts is considered probable (if contractually modified). Payments received while the finance receivable is on non-accrual status are applied to interest and principal in accordance with the contractual terms.

Finance leases are secured by the trucks and related equipment being leased and the lease terms generally range from three to five years depending on the type and use of the equipment. The lessee is required to either purchase the equipment or guarantee to the Company a stated residual value upon the disposition of the equipment at the end of the finance lease term.

Operating lease terms generally range from three to five years. At the end of the operating lease term, the lessee has the option to return the equipment to the Company or purchase the equipment at its fair market value.

The Company determines its estimate of the residual value of leased vehicles by considering the length of the lease term, the truck model, the expected usage of the truck and anticipated market demand. If the sales price of the truck at the end of the agreement differs from the Company’s estimated residual value, a gain or loss will result. Future market conditions, changes in government regulations and other factors outside the Company’s control could impact the ultimate sales price of trucks returned under these contracts. Residual values are reviewed regularly and adjusted if market conditions warrant.

NOTE C - Investments in Marketable Securities

Debt Securities

The Company's investments in marketable debt securities are classified as available-for-sale. These investments are stated at fair value and may include an allowance for credit losses. Changes in the allowance for credit losses are recognized in the current period earnings and any unrealized gains or losses, net of tax, are included as a component of accumulated other comprehensive income (loss) (AOCI).

The Company utilizes third-party pricing services for all of its marketable debt security valuations. The Company reviews the pricing methodology used by the third‑party pricing services, including the manner employed to collect market information. On a quarterly basis, the Company also performs review and validation procedures on the pricing information received from the third‑party providers. These procedures help ensure the fair value information used by the Company is determined in accordance with applicable accounting guidance.

The Company evaluates its investment in marketable debt securities at the end of each reporting period to determine if a decline in fair value is the result of credit losses or unrealized losses. In assessing credit losses, the Company considers the collectability of principal and interest payments by monitoring changes to issuers’ credit ratings, specific credit events associated with individual issuers as well as the credit ratings of any financial guarantor. The Company considers its intent for selling the security and whether it is more likely than not the Company will be able to hold the security until the recovery of any credit losses and unrealized losses. Charges against the allowance for credit losses occur when a security with credit losses is sold or the Company no longer intends to hold that security.

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.

Marketable securities at March 31, 2024 and December 31, 2023 consisted of the following:

			UNREALIZED		UNREALIZED		FAIR

The cost of marketable debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Amortization, accretion, interest and dividend income and realized gains and losses are included in investment income. The cost of securities sold is based on the specific identification method. Gross realized gains were $.6 and $.5 and gross realized losses were $1.8 and $1.6 for the three months periods ended March 31, 2024 and 2023, respectively.

Net unrealized (losses) gains on marketable equity securities were $(1.6) and $.2 for the three months periods ending March 31, 2024 and 2023, respectively.

Marketable debt securities with continuous unrealized losses and their related fair values were as follows:

	March 31, 2024				December 31, 2023
	LESS THAN		TWELVE MONTHS		LESS THAN		TWELVE MONTHS
	TWELVE MONTHS		OR GREATER		TWELVE MONTHS		OR GREATER

Unrealized losses		3.7		21.0		1.6		25.2

The unrealized losses on marketable debt securities above were due to higher yields on certain securities. The Company did not identify any indicators of a credit loss in its assessments. Accordingly, no allowance for credit losses was recorded at March 31, 2024 and December 31, 2023. The Company does not currently intend, and it is more likely than not that it will not be required, to sell the investment securities before recovery of the unrealized losses. The Company expects that the contractual principal and interest will be received on the investment securities.

Contractual maturities of marketable debt securities at March 31, 2024 were as follows:

Included in Finance and other receivables, net on the Consolidated Balance Sheets is accrued interest receivable (net of allowance for credit losses) of $87.8 and $88.4 as of March 31, 2024 and December 31, 2023, respectively. The net activity of dealer direct loans and dealer wholesale financing on new trucks is shown in the operating section of the Condensed Consolidated Statements of Cash Flows since those receivables finance the sale of Company inventory.

Allowance for Credit Losses

The Company continuously monitors the payment performance of its finance receivables. For large retail finance customers and dealers with wholesale financing, the Company regularly reviews their financial statements and makes site visits and phone contact as appropriate. If the Company becomes aware of circumstances that could cause those customers or dealers to face financial difficulty, whether or not they are past due, the customers are placed on a watch list.

The Company modifies loans and finance leases in the normal course of its Financial Services operations. The Company may modify loans and finance leases for commercial reasons or for credit reasons. Modifications for commercial reasons are changes to contract terms for customers that are not considered to be in financial difficulty. Insignificant delays are modifications extending terms up to three months for customers experiencing some short-term financial stress, but not considered to be in financial difficulty. Modifications for credit reasons are changes to contract terms for customers considered to be in financial difficulty. The Company’s modifications typically result in granting more time to pay the contractual amounts owed and charging a fee and interest for the term of the modification.

When considering whether to modify customer accounts for credit reasons, the Company evaluates the creditworthiness of the customers and modifies those accounts that the Company considers likely to perform under the modified terms. 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.

Notes to Consolidated Financial Statements (Unaudited) (Millions, Except Share Amounts)

On average, commercial and other modifications extended contractual terms by approximately three months in 2024 and three months in 2023, and did not have a significant effect on the weighted average term or interest rate of the total portfolio at March 31, 2024 and December 31, 2023.

The Company has developed a systematic methodology for determining the allowance for credit losses for its two portfolio segments, retail and wholesale. The retail segment consists of retail loans and sales-type finance leases, net of unearned interest. The wholesale segment consists of truck inventory financing loans to dealers that are collateralized by trucks and other collateral. The wholesale segment generally has less risk than the retail segment. Wholesale receivables generally are shorter in duration than retail receivables, and the Company requires periodic reporting of the wholesale dealer’s financial condition, conducts periodic audits of the trucks being financed and in many cases, obtains guarantees or other security such as dealership assets. In determining the allowance for credit losses, retail loans and finance leases are evaluated together since they relate to a similar customer base, their contractual terms require regular payment of principal and interest, generally over three to five years, and they are secured by the same type of collateral. The allowance for credit losses consists of both specific and general reserves.

The Company individually evaluates certain finance receivables for expected credit losses. Finance receivables that are evaluated individually 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. In general, finance receivables that are 90 days past due are placed on non-accrual status. Finance receivables on non-accrual status 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.

Individually evaluated receivables on non-accrual status are generally considered collateral dependent. Large balance retail and all wholesale receivables on non-accrual status are individually evaluated to determine the appropriate reserve for losses. The determination of reserves for large balance receivables on non-accrual status 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 receivables on non-accrual status 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 evaluated 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.

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.

The allowance for credit losses is summarized as follows:

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 collateral dependent. At-risk accounts are collateral dependent, including accounts over 90 days past due and other accounts on non-accrual status.

The modifications provided term extensions and granted customers additional time to pay. The financial effects of the term extensions added a weighted-average of 21 months to the life of the modified contracts for the three months ended March 31, 2024 and 2023. The effect on the allowance for credit losses from such modifications was not significant for the three months ended March 31, 2024 and 2023.

There were $1.4 finance receivables modified with customers experiencing financial difficulty during the previous twelve months that had a payment default in the three months ended March 31, 2024. There were no finance receivables modified with customers experiencing financial difficulty on or after January 1, 2023 that had a payment default in the three months ended March 31, 2023.

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 March 31, 2024 and December 31, 2023 was $32.6 and $30.4, respectively.

Proceeds from the sales of repossessed assets were $10.9 and $4.6 for the three months ended March 31, 2024 and 2023, respectively. These amounts are included in Proceeds from asset disposals in the Condensed 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 Comprehensive Income.

NOTE F - Product Support Liabilities

Product support liabilities include estimated future payments related to product warranties and deferred revenues on optional extended warranties and R&M 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.

Changes in product support liabilities are summarized as follows:

NOTE I - Segment Information

PACCAR operates in three principal segments: Truck, Parts and Financial Services. The Company evaluates the performance of its Truck and Parts segments based on operating profits, which excludes investment income, other income and expense and income taxes. The Financial Services segment’s performance is evaluated based on income before income taxes. The accounting policies of the reportable segments are the same as those applied in the consolidated financial statements as described in Note A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

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.

NOTE J - Derivative Financial Instruments

As part of its risk management strategy, the Company enters into derivative contracts to hedge against the risks of interest rates, foreign currency rates and commodity prices. Certain derivative instruments designated as fair value hedges, cash flow hedges or net investment hedges are subject to hedge accounting. Derivative instruments that are not subject to hedge accounting are held as derivatives not designated as 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 $48.1 at March 31, 2024.

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 Condensed Consolidated Statements of Cash Flows.

Interest-Rate Contracts: The Company enters into various interest-rate contracts, including interest-rate swaps and cross currency interest-rate swaps. Interest-rate swaps involve the exchange of fixed for floating rate or floating for fixed rate interest payments based on the contractual notional amounts in a single currency. Cross currency interest-rate swaps involve the exchange of notional amounts and interest payments in different currencies. The Company is exposed to interest-rate and exchange-rate risk caused by market volatility as a result of its borrowing activities. The objective of these contracts is to mitigate the fluctuations on earnings, cash flows and fair value of borrowings. Net amounts paid or received are reflected as adjustments to interest expense.

At March 31, 2024, the notional amount of the Company’s interest-rate contracts was $3,130.1. Notional maturities for all interest-rate contracts are $444.0 for the remainder of 2024, $1,008.2 for 2025, $658.7 for 2026, $317.8 for 2027, $145.5 for 2028, $555.9 for 2029 and thereafter.

Foreign-Exchange Contracts: The Company enters into foreign-exchange contracts to hedge certain anticipated transactions and assets and liabilities denominated in foreign currencies, particularly the Canadian dollar, the euro, the British pound, the Australian dollar, the Brazilian real and the Mexican peso. The objective is to reduce fluctuations in earnings and cash flows associated with changes in foreign currency exchange rates. The Company enters into foreign-exchange contracts as net investment hedges to reduce the foreign currency exposure from its investments in foreign subsidiaries. At March 31, 2024, the notional amount of the outstanding foreign-exchange contracts was $2,178.5. 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 March 31, 2024, the notional amount of the outstanding commodity contracts was $47.5. Commodity contracts mature within one year.

The loss from commodity contracts recorded in Cost of sales and revenues was $2.6 and $2.2 for the three months ended March 31, 2024 and 2023, 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:

	March 31		December 31
	2024		2023

The above table excludes the cumulative basis adjustments on discontinued hedge relationships of $9.4 and $12.2 as of March 31, 2024 and December 31, 2023, 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 Company elected to exclude the forward premium component (excluded component) on some foreign-exchange cash flow hedges and amortize the excluded component over the life of the derivative instruments. The amortization of the excluded component is recognized in Interest and other (income) expenses, net in Truck, Parts and Other segment and Interest and other borrowing expenses in Financial Services segment in the Consolidated Statements of Comprehensive Income. The maximum length of time over which the Company is hedging its exposure to the variability in future cash flows is 10.0 years.

	$	24.7	$	16.2	$	(4.6	)	$	(42.3	)	$	(21.1	)	$	(3.9	)

The amount of gain recorded in AOCI at March 31, 2024 that is estimated to be reclassified into earnings in the following 12 months if interest rates and exchange rates remain unchanged is approximately $7.2, 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 (losses) gains reclassified out of AOCI into net income based on the probability that the original forecasted transactions would not occur was $(1.9) and $.2 for the three months ended March 31, 2024 and 2023, respectively.

Net Investment Hedges

Changes in the fair value of derivatives designated as net investment hedges are recorded in AOCI as an adjustment to the Cumulative Translation Adjustment (CTA). At March 31, 2024, the notional amount of the outstanding net investment hedges was $553.8. For the three months ended March 31, 2024 and 2023, the pre-tax gain recognized in OCI for the net investment hedges were $12.2 and $.4, respectively.

NOTE K - Fair Value Measurements

Fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the 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.

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 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.

- 27 -

Notes to Consolidated Financial Statements (Unaudited) (Millions, Except Share Amounts)

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.

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, floating-rate wholesale financing and operating lease and other trade receivables, carrying values approximate fair values. For fixed rate loans, fair values are estimated using the income approach by discounting cash flows to their present value based on assumptions regarding the credit and market risks to approximate current rates for comparable loans. Finance lease receivables and related allowance for credit losses have been excluded from the accompanying table.

Debt: The carrying amounts of Financial Services commercial paper, variable rate bank loans and variable rate term notes approximate fair value. For fixed rate debt, fair values are estimated using the income approach by discounting cash flows to their present value based on current rates for comparable debt.

The Company’s estimate of fair value for fixed rate loans and debt that are not carried at fair value was as follows:

	March 31, 2024				December 31, 2023
	CARRYING		FAIR		CARRYING		FAIR
	AMOUNT		VALUE		AMOUNT		VALUE
Assets:
Financial Services fixed rate loans	$	8,334.0	$	8,267.7	$	8,126.8	$	8,214.4

NOTE M – Commitments and Contingencies

On July 19, 2016, the European Commission (EC) concluded its investigation of all major European truck manufacturers and reached a settlement with DAF Trucks N.V., DAF Trucks Deutschland GmbH and PACCAR Inc (collectively “the Company”). Following the settlement, certain EC-related claims and lawsuits have been filed in various 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 and Israel, alleging EC-related claims and seeking monetary damages. In certain jurisdictions, additional claimants may bring EC-related claims and lawsuits against the Company or its subsidiaries.

The legal proceedings are moving through the court systems. Several European courts have issued judgments; some have been favorable while others have been unfavorable and are being appealed. The Company believes it has meritorious defenses to the legal claims. In early 2023, the Company began settling with selected claimants. Based on these settlements and judgments, the Company recorded in the first quarter 2023, a non-recurring pre-tax charge of $600.0 million ($446.4 million after-tax) for the estimable total cost. The estimate may be adjusted as the legal process continues, which could have a material impact on the Company’s financial results.

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.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW:

PACCAR is a global technology company whose Truck segment includes the design and manufacture of high-quality light-, medium- and heavy-duty commercial trucks. In North America, trucks are sold under the Kenworth and Peterbilt nameplates, in Europe, under the DAF nameplate and in Australia and South America, under the Kenworth and DAF nameplates. The Parts segment includes the distribution of aftermarket parts for trucks and related commercial vehicles. The Company’s Financial Services segment derives its earnings primarily from financing or leasing PACCAR products in North America, Europe, Australia and South America. The Company’s Other business includes the manufacturing and marketing of industrial winches.

First Quarter Financial Highlights:

•Worldwide net sales and revenues were $8.74 billion in 2024 compared to $8.47 billion in 2023, due to higher truck, parts and financial services revenues.

•Truck revenues were $6.54 billion in 2024 compared to $6.41 billion in 2023, reflecting higher revenue in the U.S. and Canada.

•Parts sales were $1.68 billion in 2024 compared to $1.62 billion in 2023, primarily due to higher sales in Europe and the U.S. and Canada.

•Financial Services revenues were $509.3 million in 2024 compared to $423.2 million in 2023, primarily due to portfolio growth and higher portfolio yields.

•Net income was $1.20 billion ($2.27 per diluted share) in 2024 compared to $733.9 million ($1.40 per diluted share) in 2023. In 2023, adjusted net income (non-GAAP), excluding a $446.4 million after-tax non-recurring charge related to civil litigation in Europe was $1.18 billion ($2.25 per diluted share). See Reconciliation of GAAP to Non-GAAP Financial Measures on page 42.

•Capital investments were $164.3 million in 2024 compared to $132.9 million in 2023.

•Research and development (R&D) expenses were $105.5 million in 2024 compared to $97.2 million in 2023.

PACCAR is constructing a new, 240,000 square-foot PACCAR Parts Distribution Center (PDC) in Massbach, Germany, to be opened in 2024. The new PDC in Germany will enhance parts delivery to dealers and customers in Europe.

PACCAR’s advanced battery cell manufacturing joint venture is expected to begin construction of its 21-gigawatt hour (GWh) factory in Marshall County, Mississippi, in the second quarter of 2024, and start production in 2027. PACCAR anticipates investing $600-$900 million in the joint venture over the next several years.

The PACCAR Financial Services (PFS) group of companies has operations covering four continents and 26 countries. The global breadth of PFS and its rigorous credit application process support a portfolio of loans and leases with total assets of $21.15 billion. PFS issued $950.0 million in medium-term notes during the first three months of 2024 to support new business volume and repay maturing debt.

Truck Outlook

Truck industry heavy-duty retail sales in the U.S. and Canada in 2024 are expected to be 250,000 to 290,000 units compared to 297,000 in 2023. In Europe, 2024 truck industry registrations for over 16-tonne vehicles are expected to be 260,000 to 300,000 units compared to 343,300 in 2023. In South America, heavy-duty truck industry registrations in 2024 are projected to be 105,000 to 115,000 as compared to 105,000 in 2023.

Parts Outlook

In 2024, PACCAR Parts sales are expected to increase 4-8% compared to 2023 reflecting stable demand.

Financial Services Outlook

In 2024, average earning assets are expected to increase 3-5% compared to 2023. If freight transportation conditions decline due to a weaker economy, then past due accounts, truck repossessions and credit losses would likely increase from the current levels and new business volume would likely decline.

- 31 -

Capital Investments and R&D Outlook

Capital investments in 2024 are expected to be $700 to $750 million and R&D is expected to be $460 to $500 million. The Company is increasing its investment in new powertrains, advanced manufacturing capabilities and capacity, and aftermarket distribution capabilities and capacity.

See the Forward-Looking Statements section of Management’s Discussion and Analysis for factors that may affect these outlooks.

Factors for which the Company is unable to specifically quantify the impact include market demand, fuel prices, freight tonnage and economic conditions affecting the Company’s results of operations.

2024 Compared to 2023:

Truck

The Company’s Truck segment accounted for 75% of revenues in the first quarter of 2024 compared to 76% in the first quarter of 2023.

The Company’s new truck deliveries are summarized below:

Three Months Ended March 31,	2024	2023	% CHANGE
U.S. and Canada	29,500	26,000		13
Europe	11,600	17,400		(33	)
Mexico, South America, Australia and other	7,000	7,700		(9	)
Total units	48,100	51,100		(6	)

Worldwide new truck deliveries decreased in the first quarter of 2024 compared to the same period of 2023, primarily due to lower deliveries in Europe, mostly offset by higher deliveries in the U.S. and Canada.

- 32 -

Market share data discussed below is provided by third-party sources and is measured by either retail sales or registrations for the Company’s dealer network as a percentage of total registrations or retail sales depending on the geographic market. In the U.S. and Canada, market share is based on retail sales. In Europe, market share is based primarily on registrations.

In the first three months of 2024, industry retail sales in the heavy-duty market in the U.S. and Canada were 62,300 units compared to 72,000 units in the same period of 2023. The Company’s heavy-duty truck retail market share was 30.3% in the first three months of 2024 compared to 27.0% in the first three months of 2023. The medium-duty market was 25,200 units in the first three months of 2024 compared to 25,900 units in the same period of 2023. The Company’s medium-duty market share was 17.0% in the first three months of 2024 compared to 11.2% in the first three months of 2023.

DAF market share in the 6 to 16-tonne market in the first three months of 2024 was 9.2% compared to 9.1% in the same period of 2023.

The over 16-tonne truck market in Brasil in the first three months of 2024 was 21,000 units compared to 21,500 units in the same period of 2023. DAF Brasil market share for the first three months of 2024 was 10.7% compared to 8.6% in the same period in 2023.

The Company’s worldwide truck net sales and revenues are summarized below:

($ in millions)
Three Months Ended March 31,		2024			2023		% CHANGE
Truck net sales and revenues:
U.S. and Canada	$	4,275.5		$	3,694.0			16
Europe		1,308.2			1,803.5			(27	)
Mexico, South America, Australia and other		957.3			916.3			4

Truck income before income taxes	$	881.6		$	894.3			(1	)
Pre-tax return on revenues		13.5	%		13.9	%

The Company’s worldwide truck net sales and revenues in the first quarter increased to $6.54 billion in 2024 from $6.41 billion in 2023 from improved price realization, primarily in the U.S. and Canada, partially offset by lower truck unit deliveries, primarily in Europe.

Truck segment income before taxes and pretax return on revenues was comparable to the same period in 2023, as lower truck unit deliveries in Europe were mostly offset by higher truck deliveries in the U.S. and Canada.

The major factors for the Truck segment changes in net sales and revenues, cost of sales and revenues and gross margin between the three months ended March 31, 2024 and 2023 are as follows:

	NET			COST OF
	SALES AND			SALES AND			GROSS
($ in millions)	REVENUES			REVENUES			MARGIN
Three Months Ended March 31, 2023	$	6,413.8		$	5,372.1		$	1,041.7

Three Months Ended March 31, 2024	$	6,541.0		$	5,521.2		$	1,019.8

•Truck sales volume decreased revenues by $100.5 million and costs by $102.7 million, primarily reflecting lower truck deliveries in Europe, mostly offset by higher truck deliveries in the U.S. and Canada.

- 33 -

•Average truck sales prices increased by $177.8 million from modest price realization, primarily in the U.S. and Canada, and the positive effect of new truck models.

•Average cost per truck increased by $175.1 million, primarily reflecting higher raw material and labor costs.

•Factory overhead and other indirect costs increased $19.7 million, primarily due to higher labor costs partially offset by lower utilities and premium freight.

•Extended warranties, operating leases and other increased revenues by $25.8 million primarily due to higher volume of extended warranty and R&M contracts. The increase in extended warranty, operating leases and other cost of $39.0 million reflects higher costs from extended warranty, R&M contracts, and lower used truck results in Europe.

•The currency translation effect on sales and cost of sales primarily reflects an increase in the value of the euro and Brazilian real relative to the U.S. dollar, partially offset by a decrease in the value of Australian dollar relative to the U.S. dollar.

•Truck gross margin was 15.6% in the first quarter of 2024 compared to 16.2% in the same period of 2023 due to the factors noted above.

Truck selling, general and administrative (SG&A) expense decreased in the first quarter of 2024 to $61.7 million from $72.4 million in 2023. The decrease was primarily due to lower sales and marketing expenses and professional expenses, partially offset by higher salaries. As a percentage of sales, Truck SG&A was .9% in the first quarter of 2024 compared to 1.1% in the first quarter of 2023.

Parts

The Company’s Parts segment accounted for 19% of revenues in the first quarter of 2024 and 2023.

•Aftermarket parts sales volume increased by $3.0 million and related cost of sales increased by $1.6 million primarily reflecting higher sales volume in Mexico and Brasil, partially offset by lower sales volume in the U.S. and Canada.

•Average aftermarket parts sales prices increased sales by $43.4 million primarily due to moderate price realization in Europe and the U.S.

•Average aftermarket parts direct costs increased $22.7 million due to higher material costs, primarily in the U.S. and Europe.

- 34 -

•Warehouse and other indirect costs increased $3.5 million primarily due to higher salaries and related expenses.

•The currency translation effect on sales and cost of sales primarily reflects an increase in the value of the euro and Brazilian real and the Canadian dollar relative to the U.S. dollar, partially offset by a decrease in the value of Australian dollar relative to the U.S. dollar.

•Parts gross margins in the first quarter of 2024 increased to 32.5% from 32.2% in the first quarter of 2023 due to the factors noted above.

Parts SG&A expense increased in the first quarter of 2024 to $61.3 million from $58.1 million in 2023. The increase was primarily due to higher salaries and related expenses, partially offset by lower sales and marketing costs. As a percentage of sales, Parts SG&A was 3.7% and 3.6% in the first quarter of 2024 and 2023, respectively.

New loan and lease unit volume was $1.52 billion in the first quarter of 2024 compared to $1.43 billion in the first quarter of 2023. The increase in new loan and finance lease volume reflected a higher amount financed per truck in all markets and higher retail sales of PACCAR trucks in North America and Brasil, partially offset by lower retail sales in Europe. The decrease in equipment on operating leases new business volume reflected lower market demand in Europe, partially offset by a higher amount financed per truck

in all major markets. PFS finance market share of new PACCAR truck sales was 21.4% in the first quarter of 2024 compared to 22.0% in the first quarter of 2023.

In the first quarter of 2024, PFS revenues increased to $509.3 million from $423.2 million in 2023. The increase was primarily due to higher interest income driven by higher portfolio yields. The effects of currency translation increased PFS revenues by $9.9 million for the first quarter of 2024, primarily due to a stronger Mexican peso and euro relative to the U.S. dollar.

PFS income before income taxes decreased to $113.9 million from $148.8 million in 2023. The decrease was primarily due to lower operating lease margins, reflecting lower results on returned lease assets, partially offset by higher finance margins. The effects of currency translation increased PFS income before income taxes by $3.7 million for the first quarter of 2024, primarily due to a stronger Mexican peso relative to the U.S. dollar.

Included in Financial Services “Other assets” on the Company’s Consolidated Balance Sheets are used trucks held for sale, net of impairments, of $320.2 million at March 31, 2024 and $309.8 million at December 31, 2023. These trucks are primarily units returned from matured operating leases in the ordinary course of business, and also include trucks acquired from repossessions or through acquisitions of used trucks in trades related to new truck sales and trucks returned from residual value guarantees (RVGs).

The Company recognized losses on used trucks, excluding repossessions, of $10.9 million in the first quarter of 2024 compared to gains of $27.8 million in the first quarter of 2023, including losses on multiple unit transactions of $10.6 million in the first quarter of 2024 compared to $.7 in the first quarter of 2023. Used truck losses related to repossessions, which are recognized as credit losses, were $4.2 million for the first quarter of 2024 and not significant for the first quarter of 2023.

The major factors for the changes in interest and fees, interest and other borrowing expenses and finance margin for the three months ended March 31, 2024 and 2023 are outlined below:

•Average finance receivables increased $3.13 billion (excluding foreign exchange effects) in the first quarter of 2024 primarily due to higher average loan, finance lease and dealer wholesale balances.

•Average debt balances increased $2.30 billion (excluding foreign exchange effects) in the first quarter of 2024, reflecting higher funding requirements for the portfolio, which includes loans, finance leases, dealer wholesale and equipment on operating lease.

•Higher portfolio yields (7.2% in 2024 compared to 6.2% in 2023) increased interest and fees by $34.3 million. The higher portfolio yields were primarily due to higher market rates in all markets.

•Higher borrowing rates (4.6% in 2024 compared to 3.2% in 2023) increased interest and other borrowing expenses by $38.2 million and were primarily due to higher debt market rates in all markets.

•The currency translation effects reflect an increase in the value of foreign currencies relative to the U.S. dollar, primarily the Mexican peso, Brazilian real and euro.

Three Months Ended March 31, 2024	$	205.9		$	180.3		$	25.6

•Higher sales volume, partially offset by lower market prices of used trucks on trade, primarily in Europe, increased revenues by $12.0 million and related depreciation and other expenses by $13.0 million.

•Results on returned lease assets increased depreciation and other expenses by $31.6 million, primarily due to losses on sale of returned lease units in 2024 compared to gains in 2023 and impairment in Europe as a result of lower used truck market values.

•Average operating lease assets decreased $457.7 million (excluding foreign exchange effects), which decreased revenues by $48.6 million and related depreciation and other expenses by $43.7 million.

•Revenue per asset increased $22.2 million primarily due to higher average truck values financed and higher market rates. Cost per asset increased $33.6 million due to higher depreciation and operating expenses.

•The currency translation effects reflect an increase in the value of foreign currencies relative to the U.S. dollar, primarily the Mexican peso and the euro.

Financial Services SG&A for the first quarter of 2024 was $39.0 million compared to $35.2 million in 2023. The increase was primarily due to higher salaries and related expenses and higher professional fees. As an annualized percentage of average earnings assets, Financial Services SG&A was .8% in the first quarter of 2024 and .9% for the same period of 2023.

The provision for losses on receivables was $16.1 million in the first quarter of 2024 from $3.1 million for the same period in 2023, primarily from portfolio growth, an increase in the Company’s 30+ past due accounts in Europe and higher charge-offs. The increased charge-offs were primarily in the U.S. and Canada and Brasil, including one large fleet customer in the U.S. as well as higher average loss severity in all markets from lower used truck market values.

The Company modifies loans and finance leases as a normal part 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.

The post-modification balances of accounts modified during the three months ended March 31, 2024 and 2023 are summarized below:

	2024					2023
($ in millions)	AMORTIZED COST BASIS		% OF TOTAL PORTFOLIO*			AMORTIZED COST BASIS		% OF TOTAL PORTFOLIO*
Commercial	$	115.8		3.4	%	$	45.5		1.6	%
Insignificant delay		44.7		1.3	%		26.7		.9	%
Credit		25.6		.8	%		12.3		.4	%
	$	186.1		5.5	%	$	84.5		2.9	%

* Amortized cost basis immediately after modification as a percentage of ending retail portfolio, on an annualized basis.

Modification activity increased to $186.1 million in the first three months of 2024 from $84.5 million in the same period of 2023. The increase in modifications for Commercial reasons primarily reflects higher volumes of refinancing, primarily in the U.S. The increase in Insignificant delay modifications, which are customers requesting payment relief for up to three months, primarily reflects higher volumes of contract modifications in the U.S. The increase in Credit modifications primarily reflects higher volumes of contract modifications in Brasil.

The following table summarizes the Company’s 30+ days past due accounts:

	March 31 2024			December 31 2023			March 31 2023
Percentage of retail loan and lease accounts 30+ days past due:
U.S. and Canada		1.0	%		.8	%		.1	%
Europe		1.9	%		.5	%		.3	%
Mexico, Australia, Brasil and other		1.3	%		1.9	%		1.8	%
Worldwide		1.2	%		1.0	%		.5	%

Accounts 30+ days past due was 1.2% at March 31, 2024 compared to 1.0% at December 31, 2023 and .5% at March 31, 2023, primarily due to one large fleet customer in the U.S. and Canada and one large fleet customer in Europe. The Company continues to focus on maintaining low past due balances.

- 38 -

When the Company modifies a 30+ days past due account, the customer is then generally considered current under the revised contractual terms. The Company modified $15.3 million of accounts worldwide during the first quarter of 2024, $35.0 million during the fourth quarter of 2023 and $10.8 million during the first quarter of 2023 that were 30+ days past due and became current at the time of modification. Had these accounts not been modified and continued to not make payments, the pro forma percentage of retail loan and lease accounts 30+ days past due would have been as follows:

	March 31 2024			December 31 2023			March 31 2023
Pro forma percentage of retail loan and lease accounts 30+ days past due:
U.S. and Canada		1.0	%		.8	%		.1	%
Europe		1.9	%		1.8	%		.3	%
Mexico, Australia, Brasil and other		1.7	%		2.0	%		2.2	%
Worldwide		1.3	%		1.2	%		.6	%

Modifications of accounts in prior quarters that were more than 30 days past due at the time of modification are included in past dues if they were not performing under the modified terms at March 31, 2024, December 31, 2023 and March 31, 2023. The effect on the allowance for credit losses from such modifications was not significant at March 31, 2024, December 31, 2023 and March 31, 2023.

The Company’s annualized pre-tax return on average assets for Financial Services was 2.2% in the first quarter of 2024 compared to 3.4% in the same period of 2023.

Other

Other includes the winch business as well as sales, income and expenses not attributable to a reportable segment. Other also includes non-service cost components of pension expense and a portion of corporate expense. Other sales represent less than 1% of consolidated net sales and revenues for the first quarter of 2024 and 2023. Other SG&A decreased to $24.6 million for the first quarter of 2024 from $29.3 million for the first quarter of 2023, primarily due to lower salary related expenses.

For the first quarter of 2024, Other loss before income taxes was $2.3 million compared to $611.7 million in 2023. The decrease in Other loss before income taxes was primarily due to the $600.0 million EC-related charge in the first quarter of 2023 which is discussed in Note M of the consolidated financial statements.

Investment income for the first quarter increased to $85.5 million in 2024 from $49.0 million in 2023. The higher investment income in the first quarter of 2024 was primarily due to higher market interest rates in all regions, as well as higher investment balances.

Income Taxes

The effective tax rate for the first quarter of 2024 was 22.1% compared to 20.1% for the first quarter of 2023. Included in 2023 was the EC-related charge of $600.0 million, which lowered the effective tax rate. Excluding the EC charge and related tax benefit, the effective tax rate was 22.3%.

For the first quarter of 2024, domestic income before income taxes and pre-tax return on revenues increased primarily due to the improved results from Truck operations. For the first quarter of 2024, foreign income before taxes increased as the first three months of 2023 included the EC-related charge of $600.0 million which also reduced foreign pre-tax return on revenues in 2023.

Marketable securities		1,831.4		1,822.6
	$	8,025.9	$	9,004.3

The Company’s total cash and marketable securities at March 31, 2024 decreased $978.4 million from the balances at December 31, 2023. Total cash and marketable securities are primarily intended to provide liquidity while preserving capital.

The change in cash and cash equivalents is summarized below:

($ in millions)
Three Months Ended March 31,		2024		2023
Operating activities:
Net income	$	1,195.3		$	733.9
Net income items not affecting cash		269.0			165.7
Changes in operating assets and liabilities, net		4.7			(214.8	)

Cash and cash equivalents at beginning of period		7,181.7			4,690.9
Cash and cash equivalents at end of period	$	6,194.5		$	4,410.1

Operating activities: Cash provided by operations increased by $784.2 million to $1,469.0 million in the first three months of 2024 from $684.8 million in 2023. The increased operating cash flow reflects higher net income by $461.4 million and benefits from net changes in operating assets and liabilities of $219.5 million, primarily driven by: lower increases in trade receivables of $208.0 million and wholesale receivables on new trucks of $267.8 million in the Financial Services segment, lower cash outflows for inventories of $197.9 million and income taxes of $151.6 million, partially offset by lower increases in accruals of $597.1 million, including the EC-related charge and product support liabilities.

Investing activities: Cash used in investing activities increased by $233.4 million to $526.1 million in the first three months of 2024 from $292.7 million in 2023. The increase in net cash used in investing activities reflects increased net originations for retail loans and financing leases of $72.7 million, an increase in wholesale receivables on used equipment of $65.8 million and higher cash used in the acquisition of property, plant and equipment of $52.6 million.

Financing activities: Cash used in financing activities was $1,880.0 million for the first three months of 2024, $1,189.2 million higher than the $690.8 million used in 2023. The increase reflects higher cash dividends and lower net borrowing activity. In the first three months of 2024, the company paid $1.82 billion in dividends compared to $1.11 billion in 2023, due to a higher year-end dividend paid in January 2024. Cash used in net borrowing activities was $94.9 million, $491.9 million lower than the cash provided by net borrowing activities of $397.0 million in 2023.

Credit Lines and Other

The Company has line of credit arrangements of $4.12 billion, of which $3.63 billion were unused at March 31, 2024. Included in these arrangements are $3.00 billion of committed bank facilities, of which $1.00 billion expires in June 2024, $1.00 billion expires in June 2026 and $1.00 billion expires in June 2028. The Company intends to extend or replace these credit facilities on or before expiration. This extension or replacement could include similar borrowing capacity or upsizing the facility. These credit facilities are maintained primarily to provide backup liquidity for commercial paper borrowings and maturing medium-term notes. There were no borrowings under the committed bank facilities for the three months ended March 31, 2024.

On December 4, 2018, PACCAR’s Board of Directors approved the repurchase of up to $500.0 million of the Company’s outstanding common stock. As of March 31, 2024, the Company has repurchased $110.0 million of shares under this plan. There were no repurchases made under this plan during the three months of 2024.

- 40 -

Truck, Parts and Other

The Company provides funding for working capital, capital expenditures, R&D, dividends, stock repurchases and other business initiatives and commitments primarily from cash provided by operations. Management expects this method of funding to continue in the future.

Investments for manufacturing property, plant and equipment in the first three months of 2024 were $162.2 million compared to $127.9 million for the same period of 2023. Over the past decade, the Company’s combined investments in worldwide capital projects and R&D totaled $7.84 billion and have significantly increased the operating capacity and efficiency of its facilities and enhanced the quality and operating efficiency of the Company’s premium products.

In 2024, total capital investments for PACCAR are expected to be $700 to $750 million and R&D is expected to be $460 to $500 million. The Company is increasing its investment in advanced new trucks and powertrains, advanced manufacturing capabilities and capacity, and aftermarket distribution capabilities and capacity.

Financial Services

The Company funds its financial services activities primarily from collections on existing finance receivables and borrowings in the capital markets. The primary sources of borrowings in the capital markets are commercial paper and medium-term notes issued in the public markets and, to a lesser extent, bank loans.

In November 2021, the Company’s U.S. finance subsidiary, PACCAR Financial Corp. (PFC), filed a shelf registration under the Securities Act of 1933. The total amount of medium-term notes outstanding for PFC as of March 31, 2024 was $6.65 billion. The registration expires in November 2024 and does not limit the principal amount of debt securities that may be issued during that period.

As of March 31, 2024, the Company’s European finance subsidiary, PACCAR Financial Europe, had €907.4 million available for issuance under a €2.50 billion medium-term note program listed on the Euro MTF Market of the Luxembourg Stock Exchange. This program renews annually and expires in September 2024.

In August 2021, PACCAR Financial Mexico registered a 10.00 billion Mexican peso program with the Comision Nacional Bancaria y de Valores to issue medium-term notes and commercial paper. The registration expires in August 2026 and limits the amount of commercial paper (up to one year) to 5.00 billion Mexican pesos. At March 31, 2024, 4.32 billion Mexican pesos were available for issuance.

In August 2018, the Company’s Australian subsidiary, PACCAR Financial Pty. Ltd. (PFPL Australia), established a medium-term note program. The program does not limit the principal amount of debt securities that may be issued under the program. The total amount of medium-term notes outstanding for PFPL Australia as of March 31, 2024 was 850.0 million Australian dollars.

In May 2021, the Company’s Canadian subsidiary, PACCAR Financial Ltd. (PFL Canada), established a medium-term note program. The program does not limit the principal amount of debt securities that may be issued under the program. The total amount of medium-term notes outstanding for PFL Canada as of March 31, 2024 was 150.0 million Canadian dollars.

The Company’s Brazilian subsidiary, Banco PACCAR S.A., established a lending program in December 2021 with the local development bank, Banco Nacional de Desenvolvimento Economico e Social (BNDES) for qualified customers to receive preferential conditions and generally market interest rates. The program is limited to 1.16 billion Brazilian reais and has 896.7 million Brazilian reais outstanding as of March 31, 2024. The Brazilian subsidiary is establishing a Letra Financeira program and is intending to issue term debt in the second quarter of 2024.

The Company believes its cash balances and investments, collections on existing finance receivables, committed bank facilities and current investment-grade credit ratings of A+/A1 will continue to provide it with sufficient resources and access to capital markets at competitive interest rates and therefore contribute to the Company maintaining its liquidity and financial stability. In the event of a decrease in the Company’s credit ratings or a disruption in the financial markets, the Company may not be able to refinance its maturing debt in the financial markets. In such circumstances, the Company would be exposed to liquidity risk to the degree that the timing of debt maturities differs from the timing of receivable collections from customers. The Company believes its various sources of liquidity, including committed bank facilities, would continue to provide it with sufficient funding resources to service its maturing debt obligations.

RECONCILIATION OF GAAP TO NON-GAAP FINANCIAL MEASURES:

This Form 10-Q includes “adjusted net income (non-GAAP)” and “adjusted net income per diluted share (non-GAAP)”, which are financial measures that are not in accordance with U.S. generally accepted accounting principles (“GAAP”), since they exclude a charge for EC-related claims. These measures differ from the most directly comparable measures calculated in accordance with GAAP and may not be comparable to similarly titled non-GAAP financial measures used by other companies.

For the first quarter of 2023, adjustment for the EC-related claims relates to a pre-tax charge of $600.0 million ($446.4 million after-tax) for estimable total costs recorded in Interest and other (income) expenses, net.

Management utilizes these non-GAAP measures to evaluate the Company’s performance and believes these measures allow investors and management to evaluate operating trends by excluding a significant non-recurring charge that is not representative of underlying operating trends.

Reconciliations from the most directly comparable GAAP measures to adjusted net income (non-GAAP) and adjusted net income per diluted shares (non-GAAP) are as follows:

	Three Months Ended
($ in millions, except per share amounts)	March 31, 2023
Net income	$	733.9
EC-related claims, net of taxes		446.4
Adjusted net income (non-GAAP)	$	1,180.3
Per diluted share
Net income	$	1.40
EC-related claims, net of taxes		.85
Adjusted net income (non-GAAP)	$	2.25
After-tax return on revenues		8.7	%
EC-related claims, net of taxes		5.2	%
After-tax adjusted return on revenues (non-GAAP) *		13.9	%

EX-10.D

Exhibit (10)(d)

THIRD AMENDED AND RESTATED
PACCAR INC
RESTRICTED STOCK AND DEFERRED COMPENSATION PLAN
FOR NON-EMPLOYEE DIRECTORS
(Effective January 1, 2024)

1.PURPOSE OF THE PLAN

The Company has established this Plan to provide Non-Employee Directors with financial incentives to promote the success of the Company’s long-term business objectives, and to encourage qualified persons to accept nominations as a Non-Employee Director.

The Company hereby amends and restates the Plan effective as of January 1, 2024. The deferral feature of the Plan is intended to satisfy the requirements of section 409A of the Internal Revenue Code of 1986, as amended (“the Code”).

3.PARTICIPATION

Each Non-Employee Director of the Company shall be eligible to participate in the Plan during his or her tenure as a Director.

4.GRANTS OF RESTRICTED STOCK

(a)Except as set forth in Section 7, on the first business day of each calendar year for the duration of the Plan (the Grant Date), each person who is a Non-Employee Director shall receive a grant of Restricted Stock in an amount equal to the number of shares of Common Stock that the “Base Amount” could have purchased at the Fair Market Value on such Grant Date (rounded up to the nearest whole share). The “Base Amount” shall be $165,000 as previously established as of January 1, 2022. The Board of Directors, in its sole discretion, may adjust the Base Amount for any Grant Date; provided, that the adjusted Base Amount is established no later than the December 31 immediately prior to the Grant Date on which such Base Amount shall be effective.

(b)Shares of Restricted Stock shall vest in full and become unrestricted on the third anniversary of the applicable Grant Date subject to the provisions of Section 10. Shares of Restricted Stock may not be sold, transferred or otherwise disposed of by a Grantee until such shares become unrestricted in accordance with the provisions of this Section 4(b).

(c)Each Restricted Stock grant shall be evidenced by a written Restricted Stock Grant Agreement that shall be executed by the Grantee and an authorized Company representative which shall indicate the date of the Restricted Stock award, the number of shares of Common Stock awarded, and contain such terms and conditions as the Committee shall determine with respect to such Restricted Stock grant consistent with the Plan.

(d)Except as set forth in Section 7, a PACCAR Non-Employee Director first elected to the Board of Directors during a calendar year is entitled to a pro-rated grant of Restricted Stock. The pro-rated grant of Restricted Stock shall be calculated as follows: the number of shares of Common Stock that the Base Amount could have purchased at the Fair Market Value on the first business day the Non-Employee Director’s Board service becomes effective (the “Grant Date”) (rounded up to the nearest whole share) pro-rated to reflect the number of calendar quarters such Non-Employee Director will serve on the Board of Directors during the calendar year in which such Non-Employee Director is first elected.

5.SHARES OF COMMON STOCK SUBJECT TO THE PLAN

There shall be reserved for use under the Plan (subject to the provisions of Section 8 hereof) a total of 1,645,312 shares of Common Stock, which shares may be authorized but unissued shares of Common Stock, treasury shares, or issued shares of Common Stock that shall have been reacquired by the Company.

6.DIVIDEND, VOTING, AND OTHER SHAREHOLDER RIGHTS

Except as otherwise provided in the Plan, each Grantee shall have all of the rights of a shareholder of the Company with respect to all outstanding shares of Restricted Stock registered in his or her name, including the right to receive dividends and other distributions paid or made with respect to such shares and the right to vote such shares.

7.DEFERRAL OF COMPENSATION

A Non-Employee Director may elect, on or before December 31 of any year, to defer at least 25% of the cash compensation to be paid to the Non-Employee Director for services as a Company director during the following calendar year and/or elect to receive a credit to the Stock Unit Account in lieu of the grant of Restricted Stock described in Section 4(a). Before the term of a new Non-Employee Director begins, he or she may elect within thirty (30) days of first becoming eligible to participate in the Plan to defer payment of the cash compensation earned for the remainder of the calendar year in which his or her term begins and/or elect to receive a credit to the Stock Unit Account in lieu of the grant of Restricted Stock described in Section 4(d). Any credit to the Stock Unit Account in lieu of the grant of Restricted Stock described in Section 4(a) or 4(d) shall be for the same number of shares of Common Stock and have the same restrictions and vesting provisions otherwise applicable to the grant of Restricted Stock. Such credit to the Stock Unit Account shall be evidenced by a written Deferred Restricted Stock Unit Grant Agreement that shall be executed by the Non-Employee Director and an authorized Company representative which shall indicate the date of the Deferred Restricted Stock Unit award, the number of units awarded, and contain such terms and conditions as the Committee shall determine with respect to such Deferred Restricted Stock Unit grant consistent with the Plan.

Exhibit (10)(d)

Each participating Non-Employee Director may elect to have all or a portion of his or her cash compensation placed into one or both of two unfunded accounts maintained by the Company (hereafter Deferred Accounts). At the time a Non-Employee Director makes a deferral election, such Non-Employee Director shall specify the time and manner in which the Deferred Accounts shall be paid, using the deferral election forms prescribed by the Committee. Payment of the Deferred Accounts may be made (i) at the time of the Non-Employee Director’s Termination or (ii) based on a specific date after the Non-Employee Director’s Termination (including the date the Non-Employee Director attains a specified age). The Non-Employee Director’s deferral election form also must specify the allocation and investment of the deferred compensation between the Stock Unit Account and the Income Account. If a Non-Employee Director fails to specify the allocation and investment of the deferred compensation, then it shall be allocated and invested in the Income Account. Amounts deferred into the Stock Unit Account or the Income Account may not be transferred to the other deferred account. Notwithstanding the foregoing, if a Non-Employee Director elects to receive a credit to the Stock Unit Account in lieu of the grant of Restricted Stock described in Section 4(a) or 4(d), such credit may not be allocated to the Income Account.

(a)Stock Unit Account. In the case of cash deferrals, the account will be credited with the number of shares of Common Stock that the amount deferred could have purchased at the Fair Market Value on the date the Non-Employee Director’s cash compensation is payable. In the case of a credit to the Stock Unit Account in lieu of the grant of Restricted Stock described in Section 4(a) or 4(d), the account will be credited with the number of shares of Common Stock otherwise applicable to the grant of Restricted Stock subject to the same vesting conditions otherwise applicable to such Restricted Stock. Thereafter, any dividends earned will be treated as if those dividends had been invested in additional shares of Common Stock at the Fair Market Value on the date the dividend is payable. Vested amounts credited to the Stock Unit Account shall be distributed in shares of Common Stock either in a single payment or in substantially equal annual installments (over a period not to exceed 15 years), as specified by the Non-Employee Director on the deferral election form. Any fractional shares will be paid in cash. If a Non-Employee Director fails to specify the manner in which the Stock Unit Account shall be distributed, then it shall be distributed in a single payment.

(b)Income Account. The account will be credited with the amount deferred, and interest shall begin to accrue, as of the date the Non-Employee Director’s cash compensation is payable. Interest is credited at a rate equal to the simple combined average of the monthly Aa Industrial Bond yield averages for the immediately preceding calendar quarter as reported in Moody’s Bond Record. Interest is compounded quarterly. Amounts credited to the Income Account shall be distributed either in a single payment or in substantially equal quarterly, semi-annual or annual installments (over a period not to exceed 15 years), as specified by the Non-Employee Director on the deferral election form. If a Non-Employee Director fails to specify the manner in which the Income Account shall be distributed, then it shall be distributed in a single payment.

Unless otherwise required by applicable law, the deferral election a Non-Employee Director makes under the Plan shall remain in effect from year-to-year. A Non-Employee Director may, however, increase or decrease the amount being deferred in the future by making a new deferral election no later than the December 31 immediately preceding the calendar in which the new election is to be effective. The amounts deferred under the new deferral election shall be distributed at the time specified in the prior deferral election and the amounts deferred under the new deferral election will be allocated in accordance with the prior deferral election, unless the Non-Employee Director specifies otherwise.

A Non-Employee Director may change the time and manner in which the Deferred Accounts shall be distributed; provided that (i) the new deferral election will become effective 12 months from the date it is made and (ii) the new deferral election specifies a distribution date that is at least five (5) years later than the prior distribution date. Notwithstanding the foregoing, a change in the time and/or manner of distribution of the Deferred Accounts shall not accelerate the distribution date of the Deferred Accounts, except as allowed by section 409A of the Code and the Treasury regulations promulgated thereunder.

8.ADJUSTMENTS TO THE NUMBER OR VALUE OF SHARES OF COMMON STOCK

If there are any changes in the number or value of shares of Common Stock by reason of stock dividends, stock splits, reverse stock splits, recapitalizations, mergers, consolidations, or other events that increase or decrease the number or value of issued and outstanding shares of Common Stock, then proportionate adjustments shall be made to the number of shares of Common Stock (i) available for issuance under the Plan pursuant to Section 5 above, (ii) covered by an unvested grant of Restricted Stock, and (iii) credited to each Stock Unit Account in order to prevent

3

dilution or enlargement of rights. This provision does not, however, authorize the delivery of a fractional share of Common Stock under the Plan.

9.NON-TRANSFERABILITY

Shares of Restricted Stock and the Deferred Accounts shall not be assigned, attached, or otherwise subject to any creditor’s process or transferred except by will or the laws of descent and distribution, or pursuant to a trust created for the benefit of the Non-Employee Director or his or her family or pursuant to a qualified domestic relations order as defined by the Code, Title I of Employee Retirement Income Security Act or the rules thereunder. The restrictions set forth in Section 4(b) shall apply to the shares of Restricted Stock in the hands of the trustee or Non-Employee Director’s former spouse.

10.TERMINATION OF STATUS AS A NON-EMPLOYEE DIRECTOR

(a)In the event of a Termination by reason of Retirement, disability, or death, all shares of Restricted Stock held by the Grantee shall become fully vested, notwithstanding the provisions of Section 4(b) hereof, and the Grantee (or the Grantee’s estate or a person who acquired the shares of Restricted Stock by bequest or inheritance) shall have the right to sell, transfer, or otherwise dispose of such shares at any time. In addition, in the event of such a Termination, all vesting restrictions on the credits made to the Stock Unit Account in lieu of the grant of Restricted Stock described in Section 4(a) or 4(d) shall lapse but the payout provisions of such credits shall not be affected by such Termination.

(b)In the event of a Termination for any reason other than those specified in Section 10(a) above, any shares of Restricted Stock granted hereunder shall be forfeited and the Grantee shall return to the Company for cancellation any stock certificates representing such forfeited shares which shall be deemed to be canceled and no longer outstanding as of the date of Termination; and from and after the date of Termination, the Grantee shall cease to be a shareholder with respect to such forfeited shares and shall have no dividend, voting, or other rights with respect thereto. In addition, in the event of such a Termination, any then unvested credits made to the Stock Unit Account in lieu of the grant of Restricted Stock described in Section 4(a) or 4(d) shall be forfeited.

(c)The Deferred Accounts shall be distributed (or commence to be distributed), in accordance with the Non-Employee Director’s prior election form. If a Non-Employee Director failed to specify the time on which the Deferred Accounts shall be distributed, then such Non-Employee Director’s Deferred Accounts shall be distributed in the first January following the Non-Employee Director’s Termination.

(d)Notwithstanding a Non-Employee Director’s election, if the aggregate value of the Deferred Accounts is less than $50,000 at the time distribution is made (or is scheduled to begin), then the Deferred Accounts shall be distributed at that time in a single payment, in shares of Common Stock for the Stock Unit Account and in cash for the Income Account.

11.CHANGE IN CONTROL

Upon the occurrence of a change in control of the Company, all grants of Restricted Stock under the Plan shall vest in full and become unrestricted and nonforfeitable. In addition, all vesting restrictions on the credits made to the Stock Unit Account in lieu of the grant of Restricted Stock described in Section 4(a) or 4(d) shall lapse but the payout provisions of such credits shall not affected by such change in control. For purposes of this Section 11, a “change in control” shall have the meaning given to such term under Section 17.4 of the PACCAR Inc Long Term Incentive Plan, as approved by the shareholders of the Company on April 26, 2016. In addition, the Board or the Committee may in its sole discretion terminate the deferral feature of the Plan within the 30 days preceding or the 12 months following a “change in control event” (as such term is defined in the Treasury regulations promulgated pursuant to section 409A of the Code) and pay out deferred amounts, in accordance with Section 1.409A-3(j)(ix)(B) of the Treasury regulations promulgated pursuant to section 409A of the Code.

12.PLAN ADMINISTRATION

The Plan will be administered by the Committee. The Company will pay all costs of administration of the Plan. The Committee shall have sole discretion to interpret the Plan, amend, and rescind rules relating to its implementation and make all determinations necessary for administration of the Plan. Any determination, decision, or action of the Committee in connection with the interpretation, administration, or application of the Plan shall be final, conclusive, and binding on all persons. The Committee may employ consultants or other persons and rely upon their advice. All actions taken and all determinations made by the Committee in good faith shall be final and binding upon all Non-Employee Directors, the Company, and all interested persons. No member of the Committee shall be personally liable for any action, determination, or interpretation made in good faith with respect to the Plan.

Exhibit (10)(d)

The Committee may make such amendments or modifications in the terms and conditions of any grant of Restricted Stock as it may deem advisable, or cancel or annul any grant of Restricted Stock; provided, however, that no such amendment, modification, cancellation, or annulment may, without the consent of the Grantee, adversely affect his or her rights with respect to such grant. In addition, the Committee may amend or modify the deferral feature, provided that any such amendment or modification (i) is made in accordance with section 409A of the Code and the Treasury regulations promulgated thereunder, and (ii) does not adversely affect the Non-Employee Director’s rights thereunder without such Non-Employee Director’s written consent.

13.TAX WITHHOLDING

To the extent required by law, the Non-Employee Director (or Grantee, if applicable) shall make such arrangements satisfactory to the Company to satisfy any tax withholding or employment tax obligations due with respect to Restricted Stock or the Deferred Accounts. The Company shall have the right to withhold or deduct from any payment under the Plan in order to satisfy any applicable tax withholding obligations.

14.AMENDMENT AND TERMINATION OF THE PLAN

The Board of Directors or the Committee may at any time suspend, terminate, modify, or amend the Plan in any respect; provided, however, shareholder approval of any Plan amendment shall be obtained only if required by law or the requirements of any stock exchange on which the Common Stock is listed or quoted and provided, further, that any termination shall be subject to the requirements of section 409A of the Code. No suspension, termination, modification, or amendment of the Plan may, without the consent of the Non-Employee Director (or Grantee, if applicable), adversely affect his or her rights with respect to the Restricted Stock or his or her Deferred Accounts.

15.BENEFICIARY DESIGNATION

Each Non-Employee Director may designate a beneficiary for each outstanding grant of Restricted Stock and for payment of his or her Deferred Accounts in the event of his or her death. If no beneficiary is designated or the beneficiary does not survive the Non-Employee Director, the award shall be made to the Non-Employee Director’s surviving spouse or, if there is none, to his or her estate.

16.SECTION 409A 6-MONTH DELAY

Notwithstanding anything contained in this Plan to the contrary, if a Non-Employee Director is deemed by the Company at the time of the Non-Employee Director’s “separation from service” to be a “specified employee,” each within the meaning of section 409A of the Code, any compensation or benefits subject to section 409A of the Code to which the Non-Employee Director becomes entitled under this Plan (or any agreement or plan referenced in this Plan) in connection with such separation shall not be made or commence until the first day of the month immediately following the date that is six (6) months after the Non-Employee Director’s “separation from service” (or the Non-Employee Director’s death, if earlier). Such deferral shall only be effected to the extent required to avoid adverse tax treatment to the Non-Employee Director, including (without limitation) the additional twenty percent (20%) tax for which the Non-Employee Director would otherwise be liable under section 409A(a)(1)(B) of the Code in the absence of such deferral. Upon the expiration of the applicable deferral period, any compensation or benefits which would have otherwise been paid during that period (whether in a single sum or in installments) in the absence of this Section 16 shall be paid to the Non-Employee Director or his or her beneficiary in one lump sum.

17.EFFECTIVE DATE OF THE PLAN AND DURATION

This Plan, as amended and restated, is effective January 1, 2024 and will remain in effect until the tenth (10th) anniversary of the approval of the Plan by the shareholders of the Company at the 2024 annual meeting or, if earlier, the date the Plan is terminated by the Committee or the Board of Directors as provided herein.

Sales And Revenues [Abstract]

Sales and Revenues

NOTE B – Sales and Revenues

Truck, Parts and Other

The Company enters into sales contracts with customers associated with purchases of the Company’s products and services including trucks, parts, product support, and other related services. Generally, the Company recognizes revenue for the amount of consideration it will receive for delivering a product or service to a customer. Revenue is recognized when the customer obtains control of the product or receives benefits of the service. The Company excludes sales taxes, value added taxes and other related taxes assessed by government agencies from revenue. There are no significant financing components included in product or services revenue since generally customers pay shortly after the products or services are transferred. In the Truck and Parts segment, when the Company grants extended payment terms on selected receivables and charges interest, interest income is recognized when earned.

The following table disaggregates Truck, Parts and Other revenues by major sources:

Three Months Ended March 31,	2024		2023
Truck
Truck sales	$	6,304.7	$	6,206.0
Revenues from extended warranties, operating leases and other		236.3		207.8
		6,541.0		6,413.8
Parts
Parts sales		1,625.6		1,574.2
Revenues from dealer services and other		50.3		48.8
		1,675.9		1,623.0
Winch sales and other		18.1		13.3
Truck, Parts and Other sales and revenues	$	8,235.0	$	8,050.1

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.

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:

	March 31, 2024				December 31, 2023
	ASSETS		LIABILITIES		ASSETS		LIABILITIES
Trucks
Other current assets	$	132.7			$	147.3
Accounts payable, accrued expenses and other			$	135.7			$	149.5
Other noncurrent assets, net		171.6				186.7
Other liabilities				180.2				196.4
	$	304.3	$	315.9	$	334.0	$	345.9
Parts
Other current assets	$	92.3			$	86.8
Accounts payable, accrued expenses and other			$	226.4			$	216.3
	$	92.3	$	226.4	$	86.8	$	216.3

The Company’s total commitment to acquire trucks at a guaranteed value for contracts accounted for as a sale was $678.5 at March 31, 2024.

Revenues from extended warranties, operating leases and other include optional extended warranty and repair and maintenance (R&M) service contracts which can be purchased for periods generally ranging up to five years. The Company defers revenue based on stand-alone observable selling prices when it receives payments in advance and generally recognizes the revenue on a straight-line basis over the warranty or R&M contract periods. See Note F, Product Support Liabilities, in the Notes to the Consolidated Financial Statements for further information. Also included are truck sales with an RVG accounted for as an operating lease. A liability is created for the residual value obligation with the remainder of the proceeds recorded as deferred revenue. The deferred revenue is recognized on a straight-line basis over the guarantee period, which typically ranges from three to five years. Deferred revenue related to trucks sold with an RVG was $19.1 at March 31, 2024. The Company expects to recognize approximately $11.4 of the remaining deferred revenue in 2024, $5.0 in 2025, $1.8 in 2026, $.8 in 2027 and $.1 in 2028. Total operating lease revenue from truck sales with RVGs was $9.8 and $12.8 for the three months ended March 31, 2024 and 2023, respectively. The Company’s total commitment to acquire trucks at a guaranteed value for contracts accounted for as a lease was $108.1 at March 31, 2024.

Revenue from winch sales and other is primarily derived from the industrial winch business. Winch sales are recognized when the product is transferred to a customer, which generally occurs upon shipment. Also within this category are other revenues not attributable to a reportable segment.

Financial Services

The Company’s Financial Services segment products include loans to customers collateralized by the vehicles being financed, finance leases for retail customers and dealers, dealer wholesale financing which includes floating-rate wholesale loans to PACCAR dealers for new and used trucks, and operating leases which include rentals on Company owned equipment. Interest income from finance and other receivables is recognized using the interest method. Certain loan origination costs are deferred and amortized to interest income over the expected life of the contracts using the straight-line method which approximates the interest method.

Operating lease rental revenue is recognized on a straight-line basis over the term of the lease. Customer contracts may include additional services such as excess mileage, repair and maintenance and other services on which revenue is recognized when earned. The Company’s full-service lease arrangements bundle these additional services. Rents for full-service lease contracts are allocated between lease and non-lease components based on the relative stand-alone price of each component. Taxes, such as sales and use and value added, which are collected by the Company from a customer, are excluded from the measurement of lease income and expenses.

Recognition of interest income and rental revenue is suspended (put on non-accrual status) when the receivable becomes more than 90 days past the contractual due date or earlier if some other event causes the Company to determine that collection is not probable. Accordingly, no finance receivables more than 90 days past due were accruing interest at March 31, 2024 or December 31, 2023. Recognition is resumed if the receivable becomes current by the payment of all amounts due under the terms of the existing contract and collection of remaining amounts is considered probable (if not contractually modified) or if the customer makes scheduled payments for three months and collection of remaining amounts is considered probable (if contractually modified). Payments received while the finance receivable is on non-accrual status are applied to interest and principal in accordance with the contractual terms.

Finance leases are secured by the trucks and related equipment being leased and the lease terms generally range from three to five years depending on the type and use of the equipment. The lessee is required to either purchase the equipment or guarantee to the Company a stated residual value upon the disposition of the equipment at the end of the finance lease term.

Operating lease terms generally range from three to five years. At the end of the operating lease term, the lessee has the option to return the equipment to the Company or purchase the equipment at its fair market value.

The Company determines its estimate of the residual value of leased vehicles by considering the length of the lease term, the truck model, the expected usage of the truck and anticipated market demand. If the sales price of the truck at the end of the agreement differs from the Company’s estimated residual value, a gain or loss will result. Future market conditions, changes in government regulations and other factors outside the Company’s control could impact the ultimate sales price of trucks returned under these contracts. Residual values are reviewed regularly and adjusted if market conditions warrant.

The following table summarizes Financial Services lease revenues by lease type:

Three Months Ended March 31,	2024		2023
Finance lease revenues	$	82.6	$	54.9
Operating lease revenues		174.9		196.8

Investments in Marketable Securities

Investments, Debt and Equity Securities [Abstract]

Investments in Marketable Securities

NOTE C - Investments in Marketable Securities

Debt Securities

The Company's investments in marketable debt securities are classified as available-for-sale. These investments are stated at fair value and may include an allowance for credit losses. Changes in the allowance for credit losses are recognized in the current period earnings and any unrealized gains or losses, net of tax, are included as a component of accumulated other comprehensive income (loss) (AOCI).

The Company utilizes third-party pricing services for all of its marketable debt security valuations. The Company reviews the pricing methodology used by the third‑party pricing services, including the manner employed to collect market information. On a quarterly basis, the Company also performs review and validation procedures on the pricing information received from the third‑party providers. These procedures help ensure the fair value information used by the Company is determined in accordance with applicable accounting guidance.

The Company evaluates its investment in marketable debt securities at the end of each reporting period to determine if a decline in fair value is the result of credit losses or unrealized losses. In assessing credit losses, the Company considers the collectability of principal and interest payments by monitoring changes to issuers’ credit ratings, specific credit events associated with individual issuers as well as the credit ratings of any financial guarantor. The Company considers its intent for selling the security and whether it is more likely than not the Company will be able to hold the security until the recovery of any credit losses and unrealized losses. Charges against the allowance for credit losses occur when a security with credit losses is sold or the Company no longer intends to hold that security.

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.

Marketable securities at March 31, 2024 and December 31, 2023 consisted of the following:

			UNREALIZED		UNREALIZED		FAIR

Marketable equity securities		10.0				5.6		4.4
Total marketable securities	$	1,846.9	$	8.1	$	32.4	$	1,822.6

The cost of marketable debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Amortization, accretion, interest and dividend income and realized gains and losses are included in investment income. The cost of securities sold is based on the specific identification method. Gross realized gains were $.6 and $.5 and gross realized losses were $1.8 and $1.6 for the three months periods ended March 31, 2024 and 2023, respectively.

Net unrealized (losses) gains on marketable equity securities were $(1.6) and $.2 for the three months periods ending March 31, 2024 and 2023, respectively.

Marketable debt securities with continuous unrealized losses and their related fair values were as follows:

	March 31, 2024				December 31, 2023
	LESS THAN		TWELVE MONTHS		LESS THAN		TWELVE MONTHS
	TWELVE MONTHS		OR GREATER		TWELVE MONTHS		OR GREATER
Fair value	$	564.3	$	672.1	$	289.0	$	798.5
Unrealized losses		3.7		21.0		1.6		25.2

The unrealized losses on marketable debt securities above were due to higher yields on certain securities. The Company did not identify any indicators of a credit loss in its assessments. Accordingly, no allowance for credit losses was recorded at March 31, 2024 and December 31, 2023. The Company does not currently intend, and it is more likely than not that it will not be required, to sell the investment securities before recovery of the unrealized losses. The Company expects that the contractual principal and interest will be received on the investment securities.

Contractual maturities of marketable debt securities at March 31, 2024 were as follows:

	AMORTIZED		FAIR
	COST		VALUE
Within one year	$	490.1	$	484.9
One to five years		1,347.6		1,332.9

Included in Finance and other receivables, net on the Consolidated Balance Sheets is accrued interest receivable (net of allowance for credit losses) of $87.8 and $88.4 as of March 31, 2024 and December 31, 2023, respectively. The net activity of dealer direct loans and dealer wholesale financing on new trucks is shown in the operating section of the Condensed Consolidated Statements of Cash Flows since those receivables finance the sale of Company inventory.

Allowance for Credit Losses

The Company continuously monitors the payment performance of its finance receivables. For large retail finance customers and dealers with wholesale financing, the Company regularly reviews their financial statements and makes site visits and phone contact as appropriate. If the Company becomes aware of circumstances that could cause those customers or dealers to face financial difficulty, whether or not they are past due, the customers are placed on a watch list.

The Company modifies loans and finance leases in the normal course of its Financial Services operations. The Company may modify loans and finance leases for commercial reasons or for credit reasons. Modifications for commercial reasons are changes to contract terms for customers that are not considered to be in financial difficulty. Insignificant delays are modifications extending terms up to three months for customers experiencing some short-term financial stress, but not considered to be in financial difficulty. Modifications for credit reasons are changes to contract terms for customers considered to be in financial difficulty. The Company’s modifications typically result in granting more time to pay the contractual amounts owed and charging a fee and interest for the term of the modification.

When considering whether to modify customer accounts for credit reasons, the Company evaluates the creditworthiness of the customers and modifies those accounts that the Company considers likely to perform under the modified terms. 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.

On average, commercial and other modifications extended contractual terms by approximately three months in 2024 and three months in 2023, and did not have a significant effect on the weighted average term or interest rate of the total portfolio at March 31, 2024 and December 31, 2023.

The Company has developed a systematic methodology for determining the allowance for credit losses for its two portfolio segments, retail and wholesale. The retail segment consists of retail loans and sales-type finance leases, net of unearned interest. The wholesale segment consists of truck inventory financing loans to dealers that are collateralized by trucks and other collateral. The wholesale segment generally has less risk than the retail segment. Wholesale receivables generally are shorter in duration than retail receivables, and the Company requires periodic reporting of the wholesale dealer’s financial condition, conducts periodic audits of the trucks being financed and in many cases, obtains guarantees or other security such as dealership assets. In determining the allowance for credit losses, retail loans and finance leases are evaluated together since they relate to a similar customer base, their contractual terms require regular payment of principal and interest, generally over three to five years, and they are secured by the same type of collateral. The allowance for credit losses consists of both specific and general reserves.

The Company individually evaluates certain finance receivables for expected credit losses. Finance receivables that are evaluated individually 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. In general, finance receivables that are 90 days past due are placed on non-accrual status. Finance receivables on non-accrual status 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.

Individually evaluated receivables on non-accrual status are generally considered collateral dependent. Large balance retail and all wholesale receivables on non-accrual status are individually evaluated to determine the appropriate reserve for losses. The determination of reserves for large balance receivables on non-accrual status 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 receivables on non-accrual status 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 evaluated 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.

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.

The allowance for credit losses is summarized as follows:

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 collateral dependent. At-risk accounts are collateral dependent, including accounts over 90 days past due and other accounts on non-accrual status.

The tables below summarize the amortized cost basis of the Company’s finance receivables within each credit quality indicator by year of origination and portfolio class and current period gross charge-offs of the Company’s finance receivables by year of origination and portfolio class.

The effect on the allowance for credit losses from such modifications was not significant for the three months ended March 31, 2024 and 2023.

There were $1.4 finance receivables modified with customers experiencing financial difficulty during the previous twelve months that had a payment default in the three months ended March 31, 2024. There were no finance receivables modified with customers experiencing financial difficulty on or after January 1, 2023 that had a payment default in the three months ended March 31, 2023.

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 March 31, 2024 and December 31, 2023 was $32.6 and $30.4, respectively.

Proceeds from the sales of repossessed assets were $10.9 and $4.6 for the three months ended March 31, 2024 and 2023, respectively. These amounts are included in Proceeds from asset disposals in the Condensed 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 Comprehensive Income.

Product Warranties Disclosures [Abstract]

Product Support Liabilities

NOTE F - Product Support Liabilities

Product support liabilities include estimated future payments related to product warranties and deferred revenues on optional extended warranties and R&M 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.

Changes in product support liabilities are summarized as follows:

WARRANTY RESERVES	2024			2023
Balance at January 1	$	767.0		$	437.7
Cost accruals		181.3			163.8

Currency translation		(11.8	)		7.0
Balance at March 31	$	1,253.6		$	1,001.2

The Company expects to recognize approximately $287.7 of the remaining deferred revenue on extended warranties and R&M contracts in 2024, $355.7 in 2025, $296.4 in 2026, $185.4 in 2027, $95.5 in 2028 and $32.9 thereafter.

Segment Reporting [Abstract]

Segment Information

NOTE I - Segment Information

PACCAR operates in three principal segments: Truck, Parts and Financial Services. The Company evaluates the performance of its Truck and Parts segments based on operating profits, which excludes investment income, other income and expense and income taxes. The Financial Services segment’s performance is evaluated based on income before income taxes. The accounting policies of the reportable segments are the same as those applied in the consolidated financial statements as described in Note A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

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.

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 expenses not attributable to a reportable segment. Other also includes non-service cost components of pension expense and a portion of corporate expense.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

NOTE J - Derivative Financial Instruments

As part of its risk management strategy, the Company enters into derivative contracts to hedge against the risks of interest rates, foreign currency rates and commodity prices. Certain derivative instruments designated as fair value hedges, cash flow hedges or net investment hedges are subject to hedge accounting. Derivative instruments that are not subject to hedge accounting are held as derivatives not designated as 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 $48.1 at March 31, 2024.

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 Condensed Consolidated Statements of Cash Flows.

Interest-Rate Contracts: The Company enters into various interest-rate contracts, including interest-rate swaps and cross currency interest-rate swaps. Interest-rate swaps involve the exchange of fixed for floating rate or floating for fixed rate interest payments based on the contractual notional amounts in a single currency. Cross currency interest-rate swaps involve the exchange of notional amounts and interest payments in different currencies. The Company is exposed to interest-rate and exchange-rate risk caused by market volatility as a result of its borrowing activities. The objective of these contracts is to mitigate the fluctuations on earnings, cash flows and fair value of borrowings. Net amounts paid or received are reflected as adjustments to interest expense.

At March 31, 2024, the notional amount of the Company’s interest-rate contracts was $3,130.1. Notional maturities for all interest-rate contracts are $444.0 for the remainder of 2024, $1,008.2 for 2025, $658.7 for 2026, $317.8 for 2027, $145.5 for 2028, $555.9 for 2029 and thereafter.

Foreign-Exchange Contracts: The Company enters into foreign-exchange contracts to hedge certain anticipated transactions and assets and liabilities denominated in foreign currencies, particularly the Canadian dollar, the euro, the British pound, the Australian dollar, the Brazilian real and the Mexican peso. The objective is to reduce fluctuations in earnings and cash flows associated with changes in foreign currency exchange rates. The Company enters into foreign-exchange contracts as net investment hedges to reduce the foreign currency exposure from its investments in foreign subsidiaries. At March 31, 2024, the notional amount of the outstanding foreign-exchange contracts was $2,178.5. 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 March 31, 2024, the notional amount of the outstanding commodity contracts was $47.5. 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:

The loss from commodity contracts recorded in Cost of sales and revenues was $2.6 and $2.2 for the three months ended March 31, 2024 and 2023, 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:

	March 31		December 31
	2024		2023
Financial Services
Term notes:
Carrying amount of the hedged liabilities	$	480.0	$	128.1
Cumulative basis adjustment included in the carrying amount		3.9		7.1

The above table excludes the cumulative basis adjustments on discontinued hedge relationships of $9.4 and $12.2 as of March 31, 2024 and December 31, 2023, 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 Company elected to exclude the forward premium component (excluded component) on some foreign-exchange cash flow hedges and amortize the excluded component over the life of the derivative instruments. The amortization of the excluded component is recognized in Interest and other (income) expenses, net in Truck, Parts and Other segment and Interest and other borrowing expenses in Financial Services segment in the Consolidated Statements of Comprehensive Income. The maximum length of time over which the Company is hedging its exposure to the variability in future cash flows is 10.0 years.

The following table presents the pre-tax effects of gain (loss) on cash flow hedges recognized in other comprehensive income (loss) (OCI):

Three Months Ended March 31,	2024							2023
	INTEREST-		FOREIGN-					INTEREST-			FOREIGN-
	RATE		EXCHANGE		COMMODITY			RATE			EXCHANGE			COMMODITY
Gain (loss) recognized in OCI:
Truck, Parts and Other			$	13.5	$	(4.6	)				$	(20.1	)	$	(3.9	)
Financial Services	$	24.7		2.7				$	(42.3	)		(1.0	)
	$	24.7	$	16.2	$	(4.6	)	$	(42.3	)	$	(21.1	)	$	(3.9	)

The amount of gain recorded in AOCI at March 31, 2024 that is estimated to be reclassified into earnings in the following 12 months if interest rates and exchange rates remain unchanged is approximately $7.2, 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 (losses) gains reclassified out of AOCI into net income based on the probability that the original forecasted transactions would not occur was $(1.9) and $.2 for the three months ended March 31, 2024 and 2023, respectively.

Net Investment Hedges

Changes in the fair value of derivatives designated as net investment hedges are recorded in AOCI as an adjustment to the Cumulative Translation Adjustment (CTA). At March 31, 2024, the notional amount of the outstanding net investment hedges was $553.8. For the three months ended March 31, 2024 and 2023, the pre-tax gain recognized in OCI for the net investment hedges were $12.2 and $.4, respectively.

Fair Value Disclosures [Abstract]

Fair Value Measurements

NOTE K - Fair Value Measurements

Fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the 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.

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 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.

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, floating-rate wholesale financing and operating lease and other trade receivables, carrying values approximate fair values. For fixed rate loans, fair values are estimated using the income approach by discounting cash flows to their present value based on assumptions regarding the credit and market risks to approximate current rates for comparable loans. Finance lease receivables and related allowance for credit losses have been excluded from the accompanying table.

Debt: The carrying amounts of Financial Services commercial paper, variable rate bank loans and variable rate term notes approximate fair value. For fixed rate debt, fair values are estimated using the income approach by discounting cash flows to their present value based on current rates for comparable debt.

The Company’s estimate of fair value for fixed rate loans and debt that are not carried at fair value was as follows:

	March 31, 2024				December 31, 2023

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

NOTE M – Commitments and Contingencies

On July 19, 2016, the European Commission (EC) concluded its investigation of all major European truck manufacturers and reached a settlement with DAF Trucks N.V., DAF Trucks Deutschland GmbH and PACCAR Inc (collectively “the Company”). Following the settlement, certain EC-related claims and lawsuits have been filed in various 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 and Israel, alleging EC-related claims and seeking monetary damages. In certain jurisdictions, additional claimants may bring EC-related claims and lawsuits against the Company or its subsidiaries.

The legal proceedings are moving through the court systems. Several European courts have issued judgments; some have been favorable while others have been unfavorable and are being appealed. The Company believes it has meritorious defenses to the legal claims. In early 2023, the Company began settling with selected claimants. Based on these settlements and judgments, the Company recorded in the first quarter 2023, a non-recurring pre-tax charge of $600.0 million ($446.4 million after-tax) for the estimable total cost. The estimate may be adjusted as the legal process continues, which could have a material impact on the Company’s financial results.

PACCAR is also a defendant in various other legal proceedings and, in addition, there are various other contingent liabilities arising in the normal course of business. After consultation with legal counsel, management does not anticipate that disposition of these various other proceedings and contingent liabilities will have a material effect on the consolidated financial statements.

Accounting Policies [Abstract]

Sales and Revenues

Truck, Parts and Other

The Company enters into sales contracts with customers associated with purchases of the Company’s products and services including trucks, parts, product support, and other related services. Generally, the Company recognizes revenue for the amount of consideration it will receive for delivering a product or service to a customer. Revenue is recognized when the customer obtains control of the product or receives benefits of the service. The Company excludes sales taxes, value added taxes and other related taxes assessed by government agencies from revenue. There are no significant financing components included in product or services revenue since generally customers pay shortly after the products or services are transferred. In the Truck and Parts segment, when the Company grants extended payment terms on selected receivables and charges interest, interest income is recognized when earned.

The following table disaggregates Truck, Parts and Other revenues by major sources:

Three Months Ended March 31,	2024		2023
Truck
Truck sales	$	6,304.7	$	6,206.0
Revenues from extended warranties, operating leases and other		236.3		207.8
		6,541.0		6,413.8
Parts
Parts sales		1,625.6		1,574.2
Revenues from dealer services and other		50.3		48.8
		1,675.9		1,623.0
Winch sales and other		18.1		13.3
Truck, Parts and Other sales and revenues	$	8,235.0	$	8,050.1

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.

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:

	March 31, 2024				December 31, 2023
	ASSETS		LIABILITIES		ASSETS		LIABILITIES
Trucks
Other current assets	$	132.7			$	147.3
Accounts payable, accrued expenses and other			$	135.7			$	149.5
Other noncurrent assets, net		171.6				186.7
Other liabilities				180.2				196.4
	$	304.3	$	315.9	$	334.0	$	345.9
Parts
Other current assets	$	92.3			$	86.8
Accounts payable, accrued expenses and other			$	226.4			$	216.3
	$	92.3	$	226.4	$	86.8	$	216.3

The Company’s total commitment to acquire trucks at a guaranteed value for contracts accounted for as a sale was $678.5 at March 31, 2024.

Revenues from extended warranties, operating leases and other include optional extended warranty and repair and maintenance (R&M) service contracts which can be purchased for periods generally ranging up to five years. The Company defers revenue based on stand-alone observable selling prices when it receives payments in advance and generally recognizes the revenue on a straight-line basis over the warranty or R&M contract periods. See Note F, Product Support Liabilities, in the Notes to the Consolidated Financial Statements for further information. Also included are truck sales with an RVG accounted for as an operating lease. A liability is created for the residual value obligation with the remainder of the proceeds recorded as deferred revenue. The deferred revenue is recognized on a straight-line basis over the guarantee period, which typically ranges from three to five years. Deferred revenue related to trucks sold with an RVG was $19.1 at March 31, 2024. The Company expects to recognize approximately $11.4 of the remaining deferred revenue in 2024, $5.0 in 2025, $1.8 in 2026, $.8 in 2027 and $.1 in 2028. Total operating lease revenue from truck sales with RVGs was $9.8 and $12.8 for the three months ended March 31, 2024 and 2023, respectively. The Company’s total commitment to acquire trucks at a guaranteed value for contracts accounted for as a lease was $108.1 at March 31, 2024.

Revenue from winch sales and other is primarily derived from the industrial winch business. Winch sales are recognized when the product is transferred to a customer, which generally occurs upon shipment. Also within this category are other revenues not attributable to a reportable segment.

Inventories

Inventories are stated at the lower of cost or net realizable value. Cost of inventories is determined principally by the first-in, first-out (FIFO) method.

Allowance for Credit Losses

Allowance for Credit Losses

The Company continuously monitors the payment performance of its finance receivables. For large retail finance customers and dealers with wholesale financing, the Company regularly reviews their financial statements and makes site visits and phone contact as appropriate. If the Company becomes aware of circumstances that could cause those customers or dealers to face financial difficulty, whether or not they are past due, the customers are placed on a watch list.

The Company modifies loans and finance leases in the normal course of its Financial Services operations. The Company may modify loans and finance leases for commercial reasons or for credit reasons. Modifications for commercial reasons are changes to contract terms for customers that are not considered to be in financial difficulty. Insignificant delays are modifications extending terms up to three months for customers experiencing some short-term financial stress, but not considered to be in financial difficulty. Modifications for credit reasons are changes to contract terms for customers considered to be in financial difficulty. The Company’s modifications typically result in granting more time to pay the contractual amounts owed and charging a fee and interest for the term of the modification.

When considering whether to modify customer accounts for credit reasons, the Company evaluates the creditworthiness of the customers and modifies those accounts that the Company considers likely to perform under the modified terms. 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.

On average, commercial and other modifications extended contractual terms by approximately three months in 2024 and three months in 2023, and did not have a significant effect on the weighted average term or interest rate of the total portfolio at March 31, 2024 and December 31, 2023.

The Company has developed a systematic methodology for determining the allowance for credit losses for its two portfolio segments, retail and wholesale. The retail segment consists of retail loans and sales-type finance leases, net of unearned interest. The wholesale segment consists of truck inventory financing loans to dealers that are collateralized by trucks and other collateral. The wholesale segment generally has less risk than the retail segment. Wholesale receivables generally are shorter in duration than retail receivables, and the Company requires periodic reporting of the wholesale dealer’s financial condition, conducts periodic audits of the trucks being financed and in many cases, obtains guarantees or other security such as dealership assets. In determining the allowance for credit losses, retail loans and finance leases are evaluated together since they relate to a similar customer base, their contractual terms require regular payment of principal and interest, generally over three to five years, and they are secured by the same type of collateral. The allowance for credit losses consists of both specific and general reserves.

The Company individually evaluates certain finance receivables for expected credit losses. Finance receivables that are evaluated individually 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. In general, finance receivables that are 90 days past due are placed on non-accrual status. Finance receivables on non-accrual status 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.

Individually evaluated receivables on non-accrual status are generally considered collateral dependent. Large balance retail and all wholesale receivables on non-accrual status are individually evaluated to determine the appropriate reserve for losses. The determination of reserves for large balance receivables on non-accrual status 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 receivables on non-accrual status 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 evaluated 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.

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 $48.1 at March 31, 2024.

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 Condensed Consolidated Statements of Cash Flows.

Fair Value Measurement Policy

Fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the 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.

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 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.
