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 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 generally accepted accounting principles 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 and six months ended June 30, 2010, are not necessarily indicative of the results that may be expected for the year ending December 31, 2010. For further information, refer to the consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009.

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 June 30		Six Months Ended June 30
	2010	2009	2010	2009
Additional shares	1,182,000	939,500	1,124,000	926,000
Antidilutive options	2,142,000	3,914,000	2,142,000	3,914,000

Reclassification: In the Company’s Condensed Consolidated Statement of Cash Flows the line items “Retail loans and direct financing leases originated” and “Collections on retail loans and direct financing leases” decreased by equally offsetting amounts of $246.4 for the six months ended June 30, 2009 due to a misclassification of amounts reported in the prior period.

New Accounting Pronouncements: In July 2010 the FASB issued Accounting Standards Update (“ASU”) No. 2010-20 Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses. ASU 2010-20 amends FASB Accounting Standards Codification topic 310 – Receivables and expands disclosures about the credit quality of a company’s financing receivables and allowance for credit losses. ASU 2010-20 is effective for reporting periods ending after December 15, 2010. The Company is currently evaluating the effects of the new pronouncement on its disclosures.

NOTE B - Investments in Marketable Securities

The cost of marketable debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Amortization, accretion, interest, dividend income and realized gains and losses are included in investment income. The cost of securities sold is based on the specific identification method.

The Company’s investments in marketable securities are classified as available-for-sale. These investments are stated at fair value with any unrealized gains or losses, net of tax, included as a component of accumulated other comprehensive (loss) income. The proceeds from sales of marketable securities for the six months ended June 30, 2010 were $143.8. Gross realized gains were $.7 and nil for the six months ended June 30, 2010 and 2009, respectively, with realized losses of $.1 and nil for the six months ended June 30, 2010 and 2009, respectively.

NOTE C - Inventories

Inventories are stated at the lower of cost or market. Cost of inventories in the United States is determined principally by the last in, first out (LIFO) method. Cost of all other inventories is determined principally by the first in, first out (FIFO) method.

Inventories include the following:

	June 30 2010			December 31 2009
Finished products	$	289.1		$	312.5
Work in process and raw materials		351.8			487.5
		640.9			800.0
Less LIFO reserve		(159.5	)		(167.9	)
	$	481.4		$	632.1

Under the LIFO method of accounting (used for approximately 44% of June 30, 2010 inventories), an actual valuation can be made only at the end of each year based on year-end inventory levels and costs. Accordingly, interim valuations are based on management’s estimates of those year-end amounts.

NOTE D - Finance Receivables

Loans represent fixed- or floating-rate loans to customers collateralized by the vehicles purchased. Retail direct financing and sales-type finance leases are contracts leasing equipment to retail customers and dealers, respectively. These leases are reported as the sum of the minimum lease payments receivable and estimated residual value of the property subject to the contracts, reduced by unearned interest on finance leases which is shown separately. Dealer wholesale financing represents floating-rate wholesale loans to PACCAR dealers for new and used trucks. The loans are collateralized by the trucks being financed. Interest and other receivables are interest due on loans and leases and other amounts due in the normal course of business.

The allowance for losses for loans, leases and other are evaluated together since they relate to a similar customer base and their contractual terms require regular payment of principal and interest primarily over 36 to 60 months and are secured by the same type of collateral. The allowance for credit losses consists of both a specific reserve and a general reserve.

Finance and other receivables include the following:

	June 30 2010			December 31 2009
Loans	$	2,578.6		$  2,875.2
Retail direct financing leases		1,967.1		2,260.0
Sales-type finance leases		686.5		764.9
Dealer wholesale financing		862.8		1,015.2
Interest and other receivables		136.3		109.6
Unearned interest: Finance leases		(300.4	)	(359.6	)
		5,930.9		6,665.3
Less allowance for losses:
Loans, leases and other		(148.4	)	(157.1	)
Dealer wholesale financing		(6.9	)	(10.5	)
	$	5,775.6		$  6,497.7

NOTE E - Product Support Liabilities

Product support liabilities include reserves related to product warranties and optional extended warranties and repair and maintenance (R&M) contracts. The Company generally offers one-year warranties covering most of its vehicles and related aftermarket parts. 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 data regarding the source, frequency and cost of claims, net of any recoveries. PACCAR periodically assesses the adequacy of its recorded liabilities and adjusts them as appropriate to reflect actual experience.

Changes in warranty and R&M reserves are summarized as follows:

		2010			2009
Beginning balance, January 1	$	386.4		$	450.4
Cost accruals and revenue deferrals		84.5			116.1
Payments and revenue recognized		(99.2	)		(162.7	)
Currency translation		(37.2	)		5.5
Ending balance, June 30	$	334.5		$	409.3

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

Realized tax benefits related to the excess of deductible amounts over expense recognized amounted to $1.3 and $2.2 for the three and six months ended June 30, 2010, respectively, and $.2 and $2.1 for the three and six months ended June 30, 2009, respectively, and have been classified as a financing cash flow.

The Company issued 509,109 additional common shares under deferred and stock compensation arrangements in the six months ended June 30, 2010.

Other Capital Stock Changes

No share repurchases were completed during the six months ended June 30, 2010. In April 2010, the Company retired 409,000 of its common shares held as treasury stock.

NOTE G – Income Taxes

The effective tax rate for the second quarter and first half of 2010 was 33.0% and 31.4%, respectively, compared to 5.0% and 18.1% for the second quarter and first half of 2009. The higher tax rates in 2010 reflect a lower percentage benefit from permanent differences such as the R&D tax credit and tax exempt income and favorable provision to return adjustments in 2009.

NOTE I - Derivative Financial Instruments

Derivative financial instruments are used to hedge exposures to fluctuations in interest rates and foreign currency exchange rates. Certain derivative instruments designated as either cash flow hedges or fair value hedges are subject to hedge accounting. Derivative instruments that are not subject to hedge accounting are held as economic hedges. The Company’s policies prohibit the use of derivatives for speculation or trading. At inception of each hedge relationship, the Company documents its risk management objectives, procedures and accounting treatment. Exposure limits and minimum credit ratings are used to minimize the risks of counterparty default. The Company had no material exposures to default at June 30, 2010.

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 the fair value of borrowings. Net amounts paid or received are reflected as adjustments to interest expense.

At June 30, 2010, the notional amount of the Company’s interest-rate contracts was $3,069.8. Notional maturities for all interest-rate contracts are $641.0 for 2010, $1,083.7 for 2011, $681.6 for 2012, $345.7 for 2013, $232.8 for 2014 and $85.0 for 2015. The majority of these contracts are floating to fixed swaps that effectively convert an equivalent amount of commercial paper and other variable rate debt to fixed rates.

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 and the Mexican peso. The objective is to reduce fluctuations in earnings and cash flows associated with changes in foreign currency exchange rates. At June 30, 2010, the notional amount of the outstanding foreign-exchange contracts was $150.7. Foreign-exchange contracts mature within one year.

The Company uses regression analysis to assess and measure effectiveness of interest-rate contracts. For foreign-exchange contracts, the Company performs quarterly assessments to ensure that critical terms continue to match. Hedge accounting is discontinued prospectively when the Company determines that a derivative financial instrument has ceased to be a highly effective hedge.

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 (income) or expense recognized in earnings related to fair value hedges was included in Interest and other borrowing expenses in the Financial Services segment as follows:

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 accumulated other comprehensive income to the extent such hedges are considered effective.

Amounts in accumulated other comprehensive income are reclassified into net income in the same period in which the hedged transaction affects earnings. Net realized gains and losses from interest-rate contracts are recognized as an adjustment to interest expense. Net realized gains and losses from foreign-exchange contracts are recognized as an adjustment to cost of sales or to financial services interest expense, consistent with the hedged transaction. Gains or losses on the ineffective portion of cash flow hedges are recognized currently in earnings and were immaterial for the first and second quarters of 2010 and 2009.

The following table presents the pre-tax effects of derivative instruments recognized in earnings:

Of the $31.9 accumulated net loss on derivative contracts included in accumulated other comprehensive loss as of June 30, 2010, $34.9, net of taxes, is expected to be reclassified to interest expense or cost of sales in the following 12 months. 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.

Economic Hedges

For other risk management purposes, the Company enters into derivative instruments not designated as hedges that do not qualify for hedge accounting. These derivative instruments are used to mitigate the risk of market volatility arising from borrowings and foreign currency denominated transactions. Changes in the fair value of economic hedges are recorded in earnings in the period in which the change occurs.

The (income) or expense recognized in earnings related to economic hedges is as follows:

NOTE J - 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. The hierarchy of fair value measurements is 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 has no financial instruments requiring Level 3 valuation.

The Company uses the following methods and assumptions to measure fair value for assets and liabilities subject to recurring fair value measurements.

Marketable 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 government obligations is based on quoted prices in active markets. These are categorized as Level 1.

The fair value of municipal bonds, corporate bonds, asset-backed securities, commercial paper and term deposits is estimated using an industry standard valuation model, which is based on the income approach. The significant inputs into the valuation model include quoted interest rates, yield curves, credit rating of the security, and other observable market information. These are categorized as Level 2.

Derivative Financial Instruments: The Company’s derivative contracts consist of interest-rate swaps, cross currency swaps and foreign currency exchange contracts.

These derivative contracts are over the counter and their fair value is determined using industry standard valuation models, which are based on the income approach. The significant inputs into the valuation models include market inputs such as interest rates, yield curves, currency exchange rates, credit default swap spreads, and forward spot rates. These contracts are categorized as Level 2.

Used trucks held for sale:
Truck and Other	$  20.8	$    28.1
Financial Services	64.0	124.7
Total used trucks held for sale	$  84.8	$  152.8

The carrying amount of used trucks held for sale is written down when appropriate to reflect their fair value. The Company determines the fair value of used trucks from a matrix pricing model, which is based on the market approach. The significant observable inputs into the valuation model are recent sales prices of comparable units, the condition of the vehicles, and the number of similar units to be sold.

Used truck write-downs during the three and six months ended June 30, 2010 were $3.2 and $10.8, respectively. Of the $10.8 year-to-date cost, $3.7 was recorded as cost of sales in the truck segment and $7.1 was recorded in the financial services segment (operating lease depreciation expense of $6.4 and credit losses of $.7).

The Company used the following methods and assumptions to determine the fair value of financial instruments that are not recognized at fair value as described below.

Cash and Cash Equivalents: Carrying amounts approximate fair value.

Trade Receivables and Payables: Carrying amounts approximate fair value.

Financial Services Net Receivable: For floating-rate loans, wholesale financing, and interest and other receivables, fair values approximate carrying values. For fixed-rate loans that are not impaired, fair values are estimated using discounted cash flow analysis based on current rates for comparable loans. Finance lease receivables and the related loss provisions 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 discounted cash flow analysis based on current rates for comparable debt.

The carrying amount and fair value of fixed-rate loans and fixed-rate debt at June 30, 2010 and December 31, 2009 were as follows:

	June 30, 2010		December 31, 2009

Overview:

PACCAR is a global technology company whose principal businesses include the design, manufacture and distribution of high-quality, light, medium and heavy duty commercial trucks and related aftermarket parts and the financing and leasing of its trucks and related equipment. The Company also manufactures and markets industrial winches. The Company manages its business in two operating segments, Trucks and Financial Services. The following provides an overview of the Company’s consolidated business, followed by an analysis of the two operating segments.

PACCAR recorded higher sales and net income in the second quarter and first half of 2010 compared to the prior year. Second quarter 2010 net sales and revenues were $2.46 billion compared to $1.85 billion in the second quarter of 2009. Second quarter 2010 net income was $99.6 million ($.27 per diluted share) compared to the $26.5 million ($.07 per diluted share) earned in the second quarter of 2009. First half 2010 total net sales and revenues were $4.69 billion and $3.84 billion in the first half of 2009. First half net income in 2010 was $167.9 ($.46 per diluted share) compared to $52.8 million ($.14 per diluted share) earned in the year-earlier period.

Second quarter and first half 2010 total net sales and revenues and income before income taxes were positively affected by the translation of stronger foreign currencies, primarily the Australian and Canadian dollar. The translation effect increased second quarter sales and revenues by $11.6 million and income before income taxes by $4.2 million compared to the second quarter of 2009. For the first half, the translation effect increased sales and revenues by $124.2 million and income before income taxes by $14.4 million compared to the first half of 2009.

Net sales and revenues for the Truck and Other businesses were $2.22 billion in the second quarter of 2010 compared to $1.60 billion in the second quarter of 2009. For the first half of 2010, Truck and Other businesses net sales and revenues were $4.21 billion compared to $3.33 billion in the first half of 2009. The increase in sales and revenues for 2010 reflects higher truck unit deliveries and aftermarket parts sales worldwide.

Truck and Other Cost of sales and revenues were $1.95 billion in the second quarter of 2010 compared to $1.49 billion in the second quarter of 2009. Cost of sales and revenues were $3.72 billion in the first half

PACCAR Inc – Form 10-Q

of 2010 compared to $3.05 billion in the first half of 2009. Cost of sales and revenues increased primarily due to the higher truck unit deliveries and aftermarket parts sales.

Research and development (R&D) expenditures increased to $58.4 million in the second quarter of 2010 from $52.8 million in the second quarter of 2009 and to $113.2 million for the first half of 2010 compared to $105.1 million in the first half of 2009. The higher spending reflects increased new product development activities.

Selling, general and administrative (SG&A) expense for Truck and Other in the second quarter of 2010 was $97.3 million compared to $79.2 million in the second quarter of 2009. Year-to-date, SG&A expense was $191.4 million and $167.6 million in the first half of 2009. The higher spending reflects increased business activity world-wide, including higher sales and marketing activities ($4.9 million in the second quarter and $9.3 million in the first half of 2010) and higher pension and bonus expenses ($7.1 million in the second quarter and $6.4 million in the first half of 2010). As a percentage of sales, SG&A decreased in the second quarter to 4.4% in 2010 from 4.9% in 2009 and decreased to 4.5% in the first half of 2010 from 5.0% in the first half of 2009.

Financial Services segment revenues for the second quarter of 2010 decreased to $239.3 million from $246.6 million in the second quarter of 2009. Revenues were $485.7 million in the first half of 2010, compared to $502.4 million in the first half of 2009. The decrease in revenues in both the second quarter and first half of 2010 primarily resulted from lower average earning asset balances in all markets.

In the second quarter 2010, Financial Services income before income taxes increased by $18.4 million to $34.0 million from the $15.6 million earned in the second quarter of 2009. First half 2010 income before income taxes of $62.1 million increased $31.2 million compared to $30.9 million in the first half of 2009. The higher pre-tax income in both periods was primarily due to higher combined finance and lease margin and a lower provision for losses on receivables.

Finance margin (Interest and fee income less interest and other borrowing expenses) for the second quarter of 2010 decreased $3.5 million as the net effects of lower average finance receivables and debt of $5.8 million more than offset the benefits of lower interest rates ($2.3 million). Lease margin (Operating lease, rental and other income less Depreciation and other) increased $14.2 million in the second quarter of 2010 primarily from lower operating lease impairments and reduced losses on used trucks ($9.4 million) and higher average operating lease assets. The provision for losses on receivables for the second quarter of 2010 declined $8.9 million primarily from improvements in portfolio quality as well as a decline in the receivable balances.

Finance margin for the first half of 2010 increased $8.5 million primarily due to lower costs of economic hedges and borrowing rates ($17.7 million) that more than offset the net effects of lower average finance receivables and debt of $8.1 million. Lease margin increased $11.9 million in the first half of 2010 primarily from lower operating lease impairments and reduced losses on used trucks ($6.7 million) and higher average operating lease assets. The provision for losses on receivables for the first half of 2010 declined $12.2 million primarily from improvements in portfolio quality as well as a decline in the receivable balances. Past due accounts decreased from 4.7% in June 2009 to 4.0% in June 2010.

Investment income declined to $4.3 million and $8.8 million for the second quarter and first half of 2010, respectively, compared to $4.9 million and $12.9 million for the second quarter and first half of 2009, respectively, primarily from lower market interest rates.

The effective tax rate for the second quarter and first half of 2010 was 33.0% and 31.4%, respectively, compared to 5.0% and 18.1% for the second quarter and first half of 2009. The higher tax rates in 2010 reflect a lower percentage benefit from permanent differences such as the R&D tax credit and tax exempt income and favorable provision to return adjustments in 2009.

The Company’s return on revenues was 4.0% and 1.4% for the second quarter of 2010 and 2009, respectively, and was 3.6% and 1.4% for the first half of 2010 and 2009, respectively.

Truck

PACCAR’s truck segment, which includes the manufacture and distribution of trucks and related aftermarket parts, accounted for 89% of revenues in the second quarter and first half of 2010 compared to 86% in the second quarter and first half of 2009. In North America, trucks are sold under the Kenworth and Peterbilt nameplates and, in Europe, under the DAF nameplate.

2010 Compared to 2009:

PACCAR’s worldwide truck sales and revenues were $2.20 billion in the second quarter of 2010 compared to $1.58 billion in the second quarter of 2009. In the first half of 2010 PACCAR’s worldwide truck sales and revenues were $4.17 billion compared to the $3.29 billion in the first half of 2009. The increases in both periods were due to a higher number of trucks delivered and higher demand for the Company’s aftermarket parts both reflecting an increase in truck transportation as the world-wide economies begin to improve.

Sales and revenues in the U.S. and Canada during the second quarter of $1,071.6 million and first half of 2010 of $2,078.3 million increased compared to the prior periods in 2009. This was due to higher new truck deliveries and higher price realization on new trucks sold. The increased truck deliveries resulted from both higher heavy duty truck market share (23.0% in the first half of 2010 from 21.9% in the first half of 2009) and an increase in the size of the truck market (58,000 units in the first half of 2010 compared to 50,300 units in the first half of 2009). The higher market size reflected modestly increasing freight tonnage, stable fuel prices and some improvements in freight rates.

Sales and revenues in Europe during the second quarter of $726.6 million and first half of 2010 of $1,422.5 million increased compared to the prior periods in 2009. This was due to higher new truck deliveries and aftermarket parts sales. The increased new truck deliveries resulted from higher 15 tonne and above truck market share (16.3% in the first half of 2010 from 13.9% in the first half of 2009), partially offset by a lower market size. The 15 tonne and above truck market in Western and Central Europe decreased to 81,200 units in the first half of 2010 from 95,500 units in the first half of 2009. For the second quarter the truck market improved from 43,300 in 2009 to 43,900 in 2010 as the European economy begins to recover.

Sales and revenues in Mexico, Australia and export markets during the second quarter of $405.3 million and $668.4 million during the first half of 2010 increased compared to the prior periods in 2009. The higher sales and revenues reflect higher new truck deliveries, better price realization on truck unit sales and higher parts sales from increased market demand.

Truck segment income before income taxes increased to $114.2 million in the second quarter of 2010 from a loss of $36.5 million in the second quarter of 2009 and increased to $180.8 million in the first half of 2010 from a loss of $11.1 million in the first half of 2009. The increase was due to higher truck unit sales and margins in all markets and higher aftermarket parts sales, partially offset by increases in R&D and SG&A expenses to support increased business activity.

Net sales and revenues and gross margins for truck units and aftermarket parts are provided below. The aftermarket parts gross margin includes direct revenues and costs, but excludes certain truck segment costs.

Truck segment		12.1	%		6.8	%			11.5	%		8.2	%

Total truck segment gross margins for the second quarter and first half of 2010 increased from the comparable periods in 2009. Gross margins on trucks increased to 5.0% and 4.1% for the three and six month periods primarily due to higher price realization from stronger truck demand. For the second quarter of 2010, aftermarket parts gross margins increased due to price increases, primarily in Europe.

Truck Outlook

Heavy duty truck sales in the U.S. and Canada are expected to be in the range of 110,000–130,000 units, up slightly from 2009, reflecting uneven economic growth and an aging truck fleet. The current challenging economic conditions in Europe are expected to continue in the second half of 2010 with the annual market size of above 15-tonne vehicles expected to be in the range of 160,000–170,000 units, in line with 2009. The Company expects that the demand for trucks in its primary markets will gradually improve during the second half of 2010 and may result in some improvement in sales and margins. See the Forward Looking Statement section of Management’s Discussion and Analysis for factors that may affect this outlook.

2010 Compared to 2009:

New Loan and Lease Volume

In the second quarter and first half of 2010, new loan and lease volume increased compared to the prior year primarily due to higher retail truck sales.

- 24 -

PACCAR Inc – Form 10-Q

Revenues

PFS revenues of $239.3 million in the second quarter of 2010 and $485.7 million in the first half of 2010 declined from the comparable periods in the prior year. The lower revenues were from a decline in interest and fee income, partially offset by higher operating lease, rental and other income.

Interest and fees in the second quarter and first half of 2010 are summarized as follows:

	Three Months Ended June 30		Six Months Ended June 30
Interest and fees - 2009	$    127.0		$    259.2
Lower average asset balances	(20.8	)	(43.1	)
Decrease in yield	(1.2	)	(1.1	)
Interest and fees - 2010	$    105.0		$    215.0

The decline in loan and finance lease average earning assets was due to a reduction in retail loan and finance lease assets in North America and Europe as portfolio collections exceeded new loan and lease volume and a decline in dealer wholesale financing in Europe from lower dealer inventory levels.

Included in Operating lease, rental and other income are the following:

	Three Months Ended June 30. 2010	Three Months Ended June 30, 2009
Operating lease revenues	$    122.2	$    114.8
Used truck sales and other	12.1	4.8
Operating lease, rental and other income	$    134.3	$    119.6

Operating lease, rental and other income in the second quarter of 2010 increased $14.7 million primarily from higher average operating lease assets and higher revenue from sales of trucks acquired from PACCAR truck customers as part of new truck sales packages.

	Six Months Ended June 30. 2010	Six Months Ended June 30, 2009
Operating lease revenues	$    246.7	$    231.9
Used truck sales and other	24.0	11.3
Operating lease, rental and other income	$    270.7	$    243.2

Operating lease, rental and other income in the first half of 2010 increased $27.5 million primarily from higher average operating lease assets and higher sales of trucks.

Expenses

Interest and other borrowing expenses decreased in the second quarter and first half of 2010 compared to the second quarter and first half of 2009 due to lower average debt balances and lower borrowing rates as summarized below:

	Three Months Ended June 30		Six Months Ended June 30
Interest and other borrowing expenses - 2009	$    73.0		$    164.3
Lower average debt balances	(15.0	)	(35.0	)
Lower borrowing rates	(1.9	)	(3.6	)
Lower expense from economic hedges	(1.6	)	(14.1	)
Interest and other borrowing expenses - 2010	$    54.5		$    111.6

- 25 -

PACCAR Inc – Form 10-Q

Average debt balances decreased due to the lower level of funding needed for a smaller financial services portfolio. Borrowing rates were lower primarily due to lower expenses from economic hedges as well as a decline in market interest rates.

Included in Depreciation and other expenses are the following:

	Three Months Ended June 30, 2010	Three Months Ended June 30, 2009
Depreciation on operating lease	$      76.4	$      82.0
Vehicle operating expenses	21.6	21.2
Cost of used truck sales and other	10.1	4.4
Depreciation and other	$    108.1	$    107.6

Depreciation on operating leases declined $5.6 million in the second quarter of 2010 from lower operating lease impairments and losses on trucks returned off lease ($9.4 million) partially offset by higher depreciation on higher average operating lease assets. Cost of used truck sales and other increased $5.7 million primarily due to higher sales of units received on trade-in.

	Six Months Ended June 30, 2010	Six Months Ended June 30, 2009
Depreciation on operating lease	$    162.1	$    160.1
Vehicle operating expenses	43.6	42.6
Cost of used truck sales and other	20.4	7.8
Depreciation and other	$    226.1	$    210.5

Depreciation on operating leases increased $2.0 million the first half of 2010 due to higher depreciation on higher average operating lease assets ($8.7 million), partially offset by lower operating lease impairments and lower losses on trucks returned off lease ($6.7 million). Cost of used truck sales and other increased $12.6 million primarily due to higher sales of units received on trade-in.

Selling, general and administrative (SG&A) expense of $22.5 million in the second quarter of 2010 and $44.0 million for the first half of 2010 was comparable to the corresponding periods in the prior year due to continued cost controls.

The provision for losses on receivables includes changes to the allowance for losses on receivables related to both amounts charged-off and overall changes related to asset size and quality. For the second quarter and first half of 2010 and 2009, the provision for losses on receivables is summarized as follows:

	$	32.7	$	(3.6)	$	29.1	$	61.0	$	(6.9)	$	54.1

The provision for losses on receivables for the second quarter and first half of 2010 declined $8.9 million and $12.2 million, respectively, compared to 2009 primarily from improvements in portfolio quality as well as a decline in the receivable balances. Past due percentages are noted below.

	June 30 2010	June 30 2009	December 31 2009
Percentage of retail loan and lease accounts
30+ days past due:
U.S. and Canada	2.3%	2.8%	1.8%
Europe	5.0%	5.3%	4.4%
Mexico and Australia	8.3%	10.0%	9.5%
Total	4.0%	4.7%	3.8%

Worldwide PFS accounts 30+ days past-due at June 30, 2010 decreased to 4.0% of portfolio balances from 4.7% at June 30, 2009 from a lower past due percentage in all markets, reflecting an increase in freight tonnage. The higher freight tonnage has contributed to an increase in freight sales and freight rates for the Company’s customers and led to improvement in customers’ profits and ability to make cash payments to the Company.

Worldwide PFS accounts 30+ days past due at June 30, 2010 of 4.0% increased slightly from the 3.8% at December 31, 2009, primarily due to increases in the U.S. and Canada as well as Europe. Included in the U.S. and Canada past due percentage of 2.3% is 1.0% from one large customer. Included in the Europe past due percentage of 5.0% is 1.1% from one large customer. At June 30, 2010, the Company has $25.9 million of specific loss reserves for these and other accounts considered to have a high risk of loss. The Company continues to focus on reducing past due balances. Improving, but uneven general economic conditions will likely result in past due balances similar to current levels for the remainder of 2010.

PACCAR Inc – Form 10-Q

Financial Services Outlook

Earning assets in the second half of 2010 are expected to be slightly higher compared to current levels. Existing economic conditions will continue to exert pressure on the profit margins of truck operators and challenge some customers’ ability to make timely payments to the Company. If economic conditions continue to improve, it may lead to lower levels of past due accounts, truck repossessions and voluntary truck returns. See the Forward Looking Statement section of Management’s Discussion and Analysis for factors that may affect this outlook.

Other Business

Included in Truck and Other is the Company’s winch manufacturing business. Sales from this business represent approximately 1% of net sales for 2010 and 2009.

LIQUIDITY AND CAPITAL RESOURCES:

	June 30 2010	December 31 2009
Cash and cash equivalents	$ 1,898.1	$ 1,912.0
Marketable debt securities	294.9	219.5
	$ 2,193.0	$ 2,131.5

The Company’s total cash and marketable debt securities at June 30, 2010 increased $61.5 million in 2010 to $2,193.0 million. The Company’s total cash and cash equivalents decreased $13.9 million for the six months ended June 30, 2010 to $1,898.1 million. This was the result of $799.5 million of cash provided by operating activities, offset by $13.0 million of cash used in investing activities, $674.3 million of cash used in financing activities and a $126.1 million reduction in cash from lower foreign currencies (primarily the euro) as summarized below.

Six Months Ended June 30		2010			2009
Operating activities:
Net Income	$	167.9		$	52.8
Net income items not affecting cash		313.5			309.8
Changes in operating assets and liabilities		318.1			47.4
Net cash provided by operating activities		799.5			410.0

Effect of exchange rate changes on cash		(126.1	)		28.5
Net decrease in cash and cash equivalents		(13.9	)		(85.5	)
Cash and cash equivalents at beginning of the period		1,912.0			1,955.2
Cash and cash equivalents at end of the period	$	1,898.1		$	1,869.7

Cash provided by operations increased to $799.5 million in the first half of 2010 compared to $410.0 million in the same period of 2009, primarily due to higher net income of $115.1 million and lower pension contributions of $133.6 million. Also included in the increase in cash provided by operating activities was an increase in accounts payable and accrued expenses in 2010 compared to a decrease in 2009 ($412.3 million), partially offset by a lower decrease in wholesale receivables ($336.6 million).

Cash used in investing activities of $13.0 million in the first half of 2010 decreased $502.8 million from the $489.8 million provided in the first half of 2009. In the first half of 2010 there were higher investments in equipment on operating losses of $28.7 million and higher new loan originations of $266.4 million in the Financial Services segment compared to the prior year due to increased new truck demand. In addition, proceeds from asset disposals were $96.9 million lower in the first half of 2010 reflecting fewer used truck sales and net purchases of marketable securities were $87.5 million higher in the first half of 2010 compared to the prior year.

- 28 -

PACCAR Inc – Form 10-Q

The cash outflow from financing activities in the first half of 2010 of $674.3 million was $339.5 million lower than the first half of 2009. This was primarily due to lower repayments of long term debt of $638.3 million, partially offset by lower proceeds from long term debt of $313.9 million, reflecting lower funding required for a declining financial services asset portfolio.

Credit Lines and Other:

The Company has line of credit arrangements of $3.55 billion, of which, $3.34 billion was unused at the end of June 2010. Included in these arrangements are $3.0 billion of syndicated bank facilities. Of the $3.0 billion bank facilities, $1.0 billion matures in June 2011, $1.0 billion matures in June 2012 and $1.0 billion matures in June 2013. The Company intends to replace these credit facilities as they expire with facilities of similar amounts. 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 syndicated bank lines for the six months ended June 30, 2010.

PACCAR Inc periodically files shelf registrations under the Securities Act of 1933. The total amount of medium-term notes outstanding for PACCAR Inc as of June 30, 2010 was $870.0 million. The current registration expires in 2011 and does not limit the principal amount of debt securities that may be issued during the period.

In November 2009, 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 June 30, 2010 was $1,473.5 million. The registration expires in 2012 and does not limit the principal amount of debt securities that may be issued during the period.

At June 30, 2010, PACCAR’s European finance subsidiary, PACCAR Financial Europe, had €950 million available for issuance under a €1.5 billion medium-term note program registered with the London Stock Exchange. The program was renewed in the third quarter of 2009 and is renewable annually.

The Company believes its current investment grade credit ratings of A+/A1 will continue to provide it with access to capital markets at competitive interest rates and therefore assist the Company in maintaining its liquidity and financial stability.

The Company provides funding for working capital, capital expenditures, research and development, 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.

Expenditures for property, plant and equipment in the first six months of 2010 totaled $47.8 million compared to $30.2 million in the first six months of 2009. Capital spending in 2010 is expected to be approximately $175 - $200 million compared to $127.7 million in 2009. Research and development spending is expected to be $225 - $250 million compared to $199.2 million in 2009. PACCAR’s 2010 capital and research and development spending will continue to focus on manufacturing efficiency improvements, engine development and new product programs.

Other information on liquidity and capital resources as presented in the 2009 Annual Report to Stockholders continues to be relevant.
