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 nine month periods ended September 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 in the 2004 notes to 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 nine months ended September 30, 2004 has been reclassified to be consistent with the 2005 presentation as follows:

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.  In 2005 stock-based employee compensation expense included in net income amounted to $1.4 for the third quarter and $3.5 for the first nine 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.

	Three			Nine

	$		586.5		$	495.6

Under the LIFO method of accounting (used for approximately 50% of September 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, the Company’s interim valuations are based on management’s estimates of year-end amounts.

Comprehensive Income

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

	Three Months Ended							Nine Months Ended
	September 30							September 30
	2005			2004				2005				2004
Net income	$	304.8		$		246.7		$	820.3			$	665.4
Other comprehensive income (loss):
Foreign currency translation gains (losses)	13.5			51.2				(142.0			)	(8.2			)
Derivative contracts increase (decrease)	11.9			(7.8			)	15.6				6.6

Comprehensive income	$	329.0		$	287.2			$		693.1		$		655.0

In the third quarter of 2005, foreign currency gains were primarily due to a stronger Canadian dollar, partially offset by a slightly weaker euro and British pound relative to the US dollar. The gain in third quarter 2004 reflected increases primarily in the euro.

Foreign currency translation changes for the first nine months of both years are attributable primarily to changes in the value of the euro relative to the US 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 transactions to hedge a portion of its net investments in certain foreign operations. These transactions resulted in a $45.3 credit in the foreign currency translation component of accumulated other comprehensive income.

Accumulated Other Comprehensive Income

Accumulated other comprehensive loss is comprised of the following:

	September 30			December 31
	2005			2004
Foreign currency translation gains	$	181.4		$	323.4
Net unrealized gain (loss) on derivative contracts	11.5			(4.1		)

Total accumulated other comprehensive income	$	183.9		$	311.1

Other Capital Stock Changes

On January 1, 2005, approximately 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 nine months ended September 30, 2005, PACCAR issued 407,800 additional common shares under terms of employee stock option, deferred compensation and non-employee directors’ stock compensation arrangements. PACCAR purchased five million shares of its common stock for $343.5 million during the first nine months of 2005 and completed the stock repurchase program approved by the Board of Directors in December 2004.

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 available 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.  As of September 30, 2005, the Company had repatriated $1.25 billion of the total amount authorized.  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 indefinitely.

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

RESULTS OF OPERATIONS:

PACCAR’s total net sales and revenues for the first nine months of 2005 increased 27% to $10.42 billion from $8.21 billion in 2004. Net income for the first nine months of 2005 improved 23% to $820.3 million compared to $665.4 million in 2004. Third quarter 2005 total net sales and revenues increased 21% to $3.54 billion, from the $2.92 billion reported for the comparable period in 2004. Third quarter 2005 net income increased 24% to $304.8 million from the $246.7 million earned in the third quarter of 2004.  Net income for the first nine months of 2005 included a $64.0 million tax provision ($.37 per share) related to repatriation of certain foreign earnings.  Net income for the third quarter and first nine months of 2004 included a $9.5 million benefit resulting from the adjustment of a deferred tax asset valuation allowance related to higher expected utilization of net operating loss (NOL) carryforwards in the United Kingdom.

Truck segment net sales and revenues in the third quarter of 2005 increased 20% to $3.32 billion compared to $2.76 billion in the third quarter of 2004. Truck segment net sales for the first nine months of 2005 increased 26% to $9.80 billion.  Third quarter 2005 Truck segment income before taxes was $391.7 million, an increase of 30% compared to the $301.4 million recorded in the year-earlier period.  For the first nine months of 2005 Truck segment income before taxes of $1,137.2 million increased 36% from the $838.1 million earned in the first nine months of 2004.

Truck segment results in the third quarter and first nine months of 2005 benefited from higher production rates and aftermarket parts sales volume in all of the Company’s primary markets due to increased demand. The favorable impact of foreign currencies on sales was $8.0 million during the third quarter of 2005 and $122.6 million during the first nine months. The favorable impact of foreign currencies on pretax income was $1.7 million during the third quarter and $16.6 million for the first nine months.

Gross margins improved to 15.0% in the third quarter and 14.8% year-to-date, compared to 14.3% and 14.4% for the corresponding periods in 2004. The increase for both periods was due to improved margins realized on the sale of Peterbilt and Kenworth trucks in North America. Selling, general and administrative (SG&A) expense increased $30.4 million year-to-date and $8.0 million for the third quarter due to expenses required to support higher business volumes. As a percent of sales, SG&A decreased to 3.1% and 3.2% for the third quarter and first nine months of 2005 compared to year earlier levels of 3.4% and 3.7%, respectively.

Financial Services segment revenues increased to $195.6 million from $143.1 million for the quarter and to $549.5 million from $403.5 million for the first nine months due to higher asset levels.  Financial Services income before income taxes of $47.2 million in the third quarter 2005 increased 7% compared to the $44.1 million earned in the third quarter of 2004. For the first nine months, segment pretax earnings increased 17% to $144.4 million from $122.9 million in 2004.  The improvement is due to higher finance margins partially offset by increases in the loss provision, both of which resulted primarily from portfolio growth.

Excluding the tax provision on repatriated earnings as previously discussed, the effective rate was 33.2% for the first nine months and 33.0% for the third quarter of 2005, compared to 33.6% and 31.5% for the corresponding periods in 2004.  The lower rate in the third quarter of 2004 was due to a reduction in the deferred tax valuation allowance related to the United Kingdom NOL carryforwards.

LIQUIDITY AND CAPITAL RESOURCES:

PACCAR’s ratio of Truck and Other current assets to current liabilities at September 30, 2005 increased to 1.63 from 1.55 at December 31, 2004.

In 2005, cash provided by operating activities decreased compared to the prior year. This was primarily attributable to increases from higher net income being offset by a net increase in wholesale receivables, sales-type finance leases and direct dealer loans on new trucks, which are funded by borrowings of the financial services segment, and by changes to components of working capital. During the first nine months of 2005, in addition to dividend payments, the Company used cash to make capital additions and repurchase PACCAR common stock.  PACCAR purchased five million shares of its common stock for $343.5 million during the first nine months of 2005 and completed the stock repurchase program approved by the Board of Directors in December 2004.  An additional five million share repurchase program was approved by the Board in October, 2005.

The Company’s largest financial services subsidiary, PACCAR Financial Corp., periodically files shelf registrations under the Securities Act of 1933.  The current registration provides for the issuance of up to $3.0 billion of senior debt securities to the public.  At the end of September 2005, $1.45 billion of such securities remained available for issuance.

PACCAR’s principal European finance subsidiary, PACCAR Financial Europe B.V., had a €750 million Euro Medium Term Note Program to issue notes listed on the Luxembourg Stock Exchange.  As of September 30, 2005 the program was in the process of being updated to increase its size to €1.0 billion and list newly issued notes on the London Stock Exchange.

PACCAR and its subsidiaries replaced its $1.5 billion line of credit arrangements in July, 2005 with $1.5 billion of new credit arrangements. Of this amount, $500 million expires in July 2006 and $1.0 billion expires in July 2010. The Company intends to replace these credit facilities as they expire with facilities of similar amounts.

Other information on liquidity and sources of capital as presented in the 2004 Annual Report to Stockholders continues to be relevant.
