Notes to Consolidated Financial Statements (Unaudited)

(Millions)

NOTE A—Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance 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. As further described in Note H to these consolidated financial statements, in the second quarter of 2005, PACCAR recognized an additional $64.0 in tax expense related to the repatriation of $1.5 billion of foreign earnings as provided for under terms of the American Jobs Creation Act. Operating results for the three and six month periods ended June 30, 2005, are not necessarily indicative of the results that may be expected for the year ended December 31, 2005. 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, 2004.

Reclassifications: As more fully explained in Note B to the 2004 consolidated financial statements, PACCAR changed the classification of the cash flow effects of some lending activities in the consolidated statements of cash flows. The statement of cash flows for the second quarter of 2004 has been reclassified to be consistent with the 2005 presentation as follows:

Six Months Ended June 30, 2005	As Reclassified			As Previously Reported
OPERATING ACTIVITIES:
Change in operating assets and liabilities:
Wholesale receivables on new trucks	$	(138.0	)
Other	6.0			$	43.9

INVESTING ACTIVITIES:
Retail loans and direct financing leases originated	(1,093.6		)
Finance receivables originated				(1,188.8		)
Collections on retail loans and direct financing leases	855.8
Collections on finance receivables				913.1
Net decrease in wholesale receivables on used equipment	12.0
Net increase in wholesale receivables				(126.0		)

Stock Compensation: Under provisions of Financial Accounting Standard (FAS) No. 148, Accounting for Stock Based Compensation-Transition and Disclosure, effective January 1, 2003, PACCAR adopted prospectively the fair value recognition provisions of FAS No. 123, Accounting for Stock-Based Compensation, for all new employee stock option awards. Under these provisions, expense is recognized for the estimated fair value over the option vesting period, generally three years for the Company. Expenses, net of tax, related to all outstanding and unvested awards of stock-based employee compensation included in 2005 net income amounted to $1.2 for the second quarter and $2.1 for the first six months.

The following table illustrates the effect on net income and earnings per share as if the fair value method had been applied to all outstanding and unvested awards in 2004.

June 30, 2004	Three Months Ended			Six Months Ended
Net income, as reported	$	236.5		$	418.7
Add: stock-based employee compensation expense included in reported net income, net of related tax effects	.7			1.4
Deduct: total stock-based employee compensation expense determined under fair value method for all awards, net of related tax effects	(.9		)	(1.7		)
Pro forma net income	$	236.3		$	418.4

Earnings per share:
Basic—as reported	$	1.35		$	2.39
Basic—pro forma	1.35			2.39

Diluted—as reported	$	1.34		$	2.37
Diluted—pro forma	1.34			2.37

NOTE B—Inventories

	June 30 2005			December 31 2004
Inventories at cost:
Finished products	$	298.4		$	270.6
Work in process and raw materials	357.9			353.1
	656.3			623.7
Less LIFO reserve	(131.2		)	(128.1		)
	$	525.1		$	495.6

Under the LIFO method of accounting (used for approximately 52% of June 30, 2005, 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 C—Finance Receivables

	June 30 2005			December 31 2004
Loans	$	3,506.6		$	3,306.1

	(347.4		)	(339.8		)
	$	6,535.0		$	6,106.1

NOTE D—Product Support Liabilities

Product support liabilities consist of amounts accrued to meet product warranty obligations and deferred revenue and accrued costs associated with optional extended warranty and repair and maintenance contracts. PACCAR periodically assesses the adequacy of its recorded liabilities and adjusts them as appropriate to reflect actual experience.

Changes in product support liabilities are summarized as follows:

	2005			2004
Beginning balance, January 1	$	348.8		$	300.5
Cost accruals and revenue deferrals	137.0			121.1
Payments and revenue recognized	(114.9		)	(105.9		)
Translation	(22.6		)	(4.0		)
Ending balance, June 30	$	348.3		$	311.7

NOTE E—Stockholders’ Equity

Comprehensive Income

The components of comprehensive income, net of any related tax, were as follows:

	Three Months Ended June 30						Six Months Ended June 30
	2005			2004			2005			2004
Net income	$	241.5		$	236.5		$	515.5		$	418.7
Other comprehensive income (loss):
Foreign currency translation losses	(82.5		)	(39.7		)	(155.5		)	(59.4		)
Derivative contracts (decrease) increase	(10.4		)	19.5			3.7			14.4
Marketable securities increase (decrease)	.4			(6.8		)	.4			(5.9		)
Net other comprehensive loss	(92.5		)	(27.0		)	(151.4		)	(50.9		)
Comprehensive Income	$	149.0		$	209.5		$	364.1		$	367.8

Total comprehensive income declined for the three and six month periods ended June 30, 2005 compared to the corresponding periods in 2004. Higher levels of net income were offset by higher foreign currency translation losses in 2005 compared to 2004. Foreign currency translation adjustments in both years primarily resulted from the change in the value of the euro relative to the U.S. dollar.

In conjunction with PACCAR’s repatriation of foreign earnings under the American Jobs Creation Act (see Note H—Income Taxes for additional information), in the second quarter the Company entered into currency contracts to hedge a portion of its net investments in certain foreign operations. For the three and six months ended June 30, 2005, the increase in fair value of these contracts of $44.1 (net of tax) partially offset the foreign currency translation losses included in net other comprehensive loss. At June 30, 2005, $22.4 (net of tax) of this amount was unrealized. The remaining outstanding contracts matured in July at amounts that approximated their fair values at the end of June.

Accumulated Other Comprehensive Income

Accumulated other comprehensive income was comprised of the following:

	June 30 2005			December 31 2004
Foreign currency translation gains (including unrealized gains, net of tax, of $22.4 on currency contracts)	$	167.9		$	323.4
Net unrealized loss on derivative contracts	(.4		)	(4.1		)
Net unrealized investment gains	.7			.3
Minimum pension liability	(8.5		)	(8.5		)
Total accumulated other comprehensive income	$	159.7		$	311.1

Other Capital Stock Changes

On January 1, 2005, 752,800 stock options previously granted to PACCAR employees became exercisable. On January 20, 2005, PACCAR granted an additional 414,700 stock options at an exercise price of $72.25. These options vest January 1, 2008. In the six months ended June 30, 2005, PACCAR issued 383,000 additional common shares under terms of employee stock option, deferred compensation and non-employee directors’ stock compensation arrangements.

In the first half of 2005, PACCAR purchased 2,833,000 shares of its common stock for $193.6.

Diluted Earnings Per Share

The following table shows the additional amounts added to weighted average basic shares outstanding to calculate diluted earnings per share. These amounts primarily represent the dilutive effect of stock options. Antidilutive options (where assumed per share proceeds exceed common stock market price averages for the period) are excluded from the diluted earnings per share calculation and are shown separately.

	Three Months Ended		Six Months Ended
	June 30		June 30
	2005	2004	2005	2004
Additional shares	1,096,100	1,130,200	1,119,900	1,158,200
Excluded antidilutive shares	407,100	436,600	407,100	436,600

NOTE F—Employee Benefit Plans

PACCAR has several defined benefit pension plans, which cover a majority of its employees. The Company also provides coverage of approximately 50% of medical costs for the majority of its U.S. employees from retirement until age 65.

The following information details the components of net periodic pension cost for the Company’s defined benefit plans:

	Three Months Ended						Six Months Ended

NOTE H—Income Taxes

The American Jobs Creation Act (AJCA), which was signed into law on October 22, 2004, created a special 85% tax deduction during 2005 for certain repatriated foreign earnings that are reinvested in qualifying domestic activities, as defined in the AJCA. As previously announced, during the second quarter of 2005, PACCAR’s Board of Directors authorized the Company to repatriate $1.5 billion of foreign earnings. In accordance with FASB Staff Position No. 109-2, Accounting and Disclosure Guidance for the Foreign Earnings Repatriation Provisions within the American Jobs Creation Act of 2004, a provision of $64.0 for the repatriation of foreign earnings has been recorded as income tax expense in the second quarter of 2005. United States income taxes are not provided on any remaining undistributed earnings of the Company’s foreign subsidiaries because of the intent to reinvest these earnings.

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

RESULTS OF OPERATIONS:

PACCAR’s second quarter 2005 total net sales and revenues increased 28% to a record $3.56 billion compared to $2.79 billion reported for the second quarter in 2004. First half net sales and revenues increased 30% to $6.88 billion. Second quarter 2005 net income was $241.5 million ($1.39 per share diluted), up 2% from the $236.5 million ($1.34 per share diluted) earned in the second quarter of 2004. First half net income increased 23% to a record $515.5 million.

As previously announced, during the second quarter of 2005, PACCAR’s Board of Directors authorized the Company to repatriate $1.5 billion of foreign earnings. Accordingly, net income for the second quarter and first half of 2005 included a $64.0 million tax provision ($.37 per share) related to the repatriation of certain foreign earnings pursuant to the AJCA.

Truck segment net sales and revenues in the second quarter of 2005 increased 27% to $3.35 billion compared to $2.64 billion in the second quarter of 2004. First half 2005 Truck segment net sales increased 30% to $6.48 billion. Second quarter 2005 Truck segment income before taxes was $386.6 million compared to the $303.2 million recorded in the year-earlier period. The first half 2005 Truck segment income before taxes of $745.5 million increased 39% from the $536.7 million earned in the first half of 2004.

Truck segment results in the second quarter and first half of 2005 benefited from higher production rates and aftermarket parts sales volumes due to increased demand. The favorable impact of foreign currencies on sales was $57.4 million during the second quarter of 2005 and $114.6 during the first half. The favorable impact of foreign currencies on pretax income was $7.7 million during the second quarter and $14.9 million during the first half.

Gross margins were 14.7% in both the second quarter and first half of 2005 compared to 15.0% in the second quarter and 14.5% in the first half of 2004. Selling, general and administrative (SG&A) expense increased $12.8 million for the quarter and $22.4 million year-to-date. The increase for both periods was due primarily to costs associated with supporting business growth. As a percent of sales, however, SG&A decreased to a record low of 3.1% and 3.3% for the second quarter and first half of 2005, respectively, compared to year earlier levels of 3.5% and 3.8%, respectively.

Financial Services segment revenues increased 37% to $182.5 million from $133.4 million for the quarter and to $353.9 million from $260.4 million for the first half due to higher portfolio levels and interest rates. Financial Services income before income taxes of $49.9 million in second quarter 2005 increased 21% compared to the $41.3 million earned in the second quarter of 2004. For the first half, segment pretax earnings increased 23% to $97.2 million from $78.8 million in 2004. The improvement was due primarily to net earnings from higher portfolio balances.

Excluding the tax provision on repatriated earnings noted above, the effective tax rate was 32.5% for the second quarter and 33.3% for the first six months of 2005 compared to 34.8% and 34.7% for the comparable periods in 2004.
