PART I

ITEM 1.BUSINESS.

(a) General Development of Business

PACCAR Inc (the Company), incorporated under the laws of Delaware in 1971, is the successor to Pacific Car and Foundry Company which was incorporated in Washington in 1924. The Company traces its predecessors to Seattle Car Manufacturing Company formed in 1905.

(b) Financial Information About Industry Segments and Geographic Areas

Information about the Company’s industry segments and geographic areas in response to Items 101(b), (c)(1)(i), and (d) of Regulation S-K appears on page 49 of the Annual Report to Stockholders for the year ended December 31, 2007 and is incorporated herein by reference.

(c) Narrative Description of Business

The Company has two principal industry segments, (1) design, manufacture and distribution of light-, medium- and heavy-duty trucks and related aftermarket distribution of parts and (2) finance and leasing services provided to customers and dealers. The Company’s finance and leasing activities are principally related to Company products and associated equipment. Other manufactured products include industrial winches.

TRUCKS

The Company and its subsidiaries design and manufacture heavy-duty diesel trucks which are marketed under the Kenworth, Peterbilt and DAF nameplates. These trucks, which are built in four plants in the United States, three in Europe and one each in Australia, Canada and Mexico, are used world-wide for over-the-road and off-highway hauling of freight, petroleum, wood products, construction and other materials. The Company competes in the North American Class 5-7 markets primarily with conventional models.  These trucks are assembled at facilities in Ste. Therese, Canada and in Mexicali, Mexico, which are operated by the Company’s wholly owned subsidiaries located in those countries. The Company competes in the European light/medium (6 to 15 metric ton) market with DAF cab-over-engine trucks assembled in the United Kingdom by Leyland, one of the Company’s wholly owned subsidiaries. Commercial trucks and related replacement parts comprise the largest segment of the Company’s business, accounting for 91% of total 2007 net sales and revenues.

Substantially all trucks and related parts are sold to independent dealers. The Kenworth and Peterbilt nameplates are marketed and distributed by separate divisions in the U.S. and a foreign subsidiary in Canada. The Kenworth nameplate is also marketed and distributed by foreign subsidiaries in Mexico and Australia. The DAF nameplate is marketed and distributed by a foreign subsidiary headquartered in the Netherlands. A U.S. division, PACCAR International, also markets all three nameplates outside each of their primary markets. The decision to operate as a subsidiary or as a division is incidental to Truck Segment operations and reflects legal, tax and regulatory requirements in the various countries where PACCAR operates.

2

The Truck Segment utilizes centrally managed purchasing, information technology, technical research and testing, treasury and finance functions. Certain manufacturing plants in North America produce trucks for more than one nameplate in common production facilities, while other plants produce trucks for only one nameplate, depending on various factors. As a result of the close similarity of the business models employed by each nameplate, best manufacturing practices within the Company are shared on a routine basis.

The Company’s trucks are essentially custom products and have a reputation for high quality. For a significant portion of the Company’s truck operations, major components, such as engines, transmissions and axles, as well as a substantial percentage of other components, are purchased from component manufacturers pursuant to PACCAR and customer specifications. DAF, which is more vertically integrated, manufactures its own engines and axles and a higher percentage of other components for its heavy truck models. The value of truck components manufactured by independent suppliers ranges from approximately 45% in Europe to approximately 90% in North America.

Raw materials and other components used in the manufacture of trucks are purchased from a number of suppliers. The Company’s DAF subsidiary purchases fully assembled cabs from a competitor, Renault V.I., for its European light-duty product line pursuant to a joint product development and long-term supply contract. Sales of trucks manufactured with these cabs amounted to approximately 4% of consolidated revenues in 2007. A short-term loss of supply, and the resulting interruption in the production of these trucks, would not have a material effect on the Company’s results of operations. However, a loss of supply for an extended period of time would either require the Company to contract for an alternative source of supply or to manufacture cabs itself. Other than these components, the Company is not limited to any single source for any significant component, although the sudden inability of a supplier to deliver components could have a temporary adverse effect on production of certain products. No significant shortages of materials or components were experienced in 2007. Manufacturing inventory levels are based upon production schedules and orders are placed with suppliers accordingly.

Replacement truck parts are sold and delivered to the Company’s independent dealers through the Company’s parts distribution network. Parts are both manufactured by the Company and purchased from various suppliers. Replacement parts inventory levels are determined largely by anticipated customer demand and the need for timely delivery. As a percentage of total consolidated net sales and revenues, parts sales were 15.0% in 2007, 11.8% in 2006, and 12.0% in 2005.

There were three other principal competitors in the U.S. and Canada Class 8 truck market in 2007. The Company’s share of the U.S. and Canadian market was 26.4% of retail sales in 2007.  In Europe there were five other principal competitors in the commercial vehicle market in 2007, including parent companies to two competitors of the Company in the United States. In 2007, DAF had a 13.9% share of the Western and Central European heavy-duty market and a 8.3% share of the light/medium market. These markets are highly competitive in price, quality and service, and PACCAR is not dependent on any single customer for its sales. There are no significant seasonal variations in sales.

The Peterbilt, Kenworth, and DAF nameplates are recognized internationally and play an important role in the marketing of the Company’s truck products. The Company engages in a continuous program of trademark and trade name protection in all marketing areas of the world.

3

The Company’s truck products are subject to environmental noise and emission regulations and competing manufacturers are subject to the same regulations. The Company believes the cost of complying with noise and emission regulations will not be detrimental to its business.

The Company had a total production backlog of $4.7 billion at the end of 2007. Within this backlog, orders scheduled for delivery within three months (90 days) are considered to be firm. The 90-day backlog approximated $2.2 billion at December 31, 2007, $2.7 billion at December 31, 2006 and $2.5 billion at December 31, 2005. Production of the year-end 2007 backlog is expected to be substantially completed during 2008.

OTHER BUSINESS

The Truck and Other businesses include a division of the Company which manufactures industrial winches in two U.S. plants and markets them under the Braden, Carco, and Gearmatic nameplates. The markets for these products are highly competitive and the Company competes with a number of well established firms. Sales of industrial winches were approximately 1% of net sales and revenues in 2007, 2006 and 2005.

The Braden, Carco, and Gearmatic trademarks and trade names are recognized internationally and play an important role in the marketing of those products.

FINANCIAL SERVICES

In North America, Australia and 14 European countries, the Company provides financing and leasing arrangements, principally for its manufactured trucks, through wholly owned finance companies operating under the PACCAR Financial trade name. They provide inventory financing for independent dealers selling PACCAR products, and retail and lease financing for new and used trucks and other transportation equipment sold principally by its independent dealers. Receivables are secured by the products financed or leased.

The Company also conducts full service leasing operations through wholly owned subsidiaries in North America and Germany under the PacLease trade name. Selected dealers in North America are franchised to provide full service leasing. The Company provides its franchisees equipment financing and administrative support. The Company also operates full service lease outlets on its own behalf.

PATENTS

The Company owns numerous patents which relate to all product lines. Although these patents are considered important to the overall conduct of the Company’s business, no patent or group of patents is considered essential to a material part of the Company’s business.

REGULATION

As a manufacturer of highway trucks, the Company is subject to the National Traffic and Motor Vehicle Safety Act and Federal Motor Vehicle Safety Standards promulgated by the National Highway Traffic Safety Administration as well as environmental laws and regulations in the United States, and is subject to similar regulations in Canada, Mexico, Australia and Europe. In addition, the Company is subject to certain other licensing requirements to do business in the United States and Europe. The Company believes it is in compliance with laws and regulations applicable to safety standards, the environment and other licensing requirements in all countries where it has operations.

4

Information regarding the effects that compliance with international, federal, state and local provisions regulating the environment have on the Company’s capital and operating expenditures and the Company’s involvement in environmental cleanup activities is included in Management’s Discussion and Analysis of Financial Condition and Results of Operations and the Company’s Consolidated Financial Statements incorporated by reference in Items 7 and 8, respectively.

EMPLOYEES

On December 31, 2007, the Company had approximately 21,800 employees.

OTHER DISCLOSURES

The Company’s filings on Form 10-K, 10-Q, and 8-K and any amendments to those reports can be found on the Company’s website www.paccar.com free of charge as soon as practicable after the report is electronically filed with, or furnished to, the Securities and Exchange Commission. The information on the Company’s website is not incorporated by reference into this report.

ITEM 1A.RISK FACTORS.

The following are significant risks which could negatively impact the Company’s financial condition or results of operations.

Business and Industry Risks

The commercial truck market demand is variable.  Demand for commercial vehicles depends to some extent on economic and other conditions in a given market and the introduction of new vehicles and technologies.  The yearly demand for commercial vehicles may increase or decrease more than overall gross domestic product in markets the Company serves which are principally North America and Western Europe. Demand may also be affected by factors impacting new truck prices such as costs of raw materials and components and cost of compliance with governmental regulations (including tariffs, engine emissions regulations, import regulations and taxes).

The financial services industry is highly competitive.  The Company competes with banks, other commercial finance companies and financial services firms which may have lower costs of borrowing, higher leverage or market share goals that result in a willingness to offer lower interest rates, which may lead to decreased margins, lower market share or both. A decline in the Company’s commercial truck unit sales, an increase in residual value risk due to lower used truck pricing and increased funding costs are also factors which may negatively affect the Company’s financial services operations.

The financial services segment is subject to credit risk.  The financial services segment is exposed to the risk of loss arising from the failure of a customer, dealer or counterparty to meet the terms of the loans, leases and derivative contracts with the Company. Although the financial assets of the financial services segment are secured by underlying equipment collateral, in the event a customer cannot meet its obligations to the Company, there is a risk that the value of the underlying collateral will not be sufficient to recover the amounts owed to the Company resulting in credit losses.

5

Political, Regulatory and Economic Risks

The Company’s operations could be subject to currency and interest rate fluctuations.  The Company’s consolidated financial statements, which are presented in U.S. dollars, are affected by foreign currency exchange fluctuations through both translation and transaction risk.  The Company uses certain derivative financial instruments and localized production of its products to reduce, but not eliminate, the effects of interest rate and foreign currency exchange rate fluctuations.

The Company may be adversely affected by political instabilities, fuel shortages or interruptions in transportation systems, natural calamities, wars, terrorism and labor strikes.  The Company is subject to various risks associated with conducting business worldwide.

ITEM 1B.UNRESOLVED STAFF COMMENTS.

Not applicable.

ITEM 2.PROPERTIES.

The Company and its subsidiaries own and operate manufacturing plants in five U.S. states, three countries in Europe, and one each in Australia, Canada and Mexico. The Company also has a number of parts distribution centers, sales and service offices, and finance and administrative offices which are operated in owned or leased premises in these and other countries. Facilities for product testing and research and development are located in Washington state and the Netherlands. The Company’s corporate headquarters is located in owned premises in Bellevue, Washington. The Company considers all of the properties used by its businesses to be suitable for their intended purposes.

Substantially all the Company’s manufacturing facilities increased their capacity in 2007 compared to the prior year. The Company continuously invests in facilities, equipment and processes to provide manufacturing and warehouse capacity to meet its customers’ needs.

Construction of PACCAR’s new engine production facility and technology center in Columbus, Mississippi began in July 2007 and is expected to be completed in late 2009.  PACCAR’s 12.9-liter and 9.2-liter diesel engines manufactured in Columbus will be installed in Kenworth and Peterbilt trucks and may be exported to meet DAF’s production requirements.

The following summarizes the number of the Company’s manufacturing plants in operation by geographical location within indicated industry segments:

	U.S.	Canada	Australia	Mexico	Europe
Truck	4	1	1	1	3
Other	2	—	—	—	—

ITEM 3.LEGAL PROCEEDINGS.

STOCKHOLDER RETURN PERFORMANCE GRAPH

The following line graph compares the yearly percentage change in the cumulative total stockholder return on the Company’s common stock to the cumulative total return of the Standard & Poor’s Composite 500 Stock Index and the return of an industry peer group of companies identified in the graph (the Peer Group Index) for the last five years ending December 31, 2007. Standard & Poor’s has calculated a return for each company in the Peer Group Index weighted according to its respective capitalization at the beginning of each period with dividends reinvested on a monthly basis. Management believes that the identified companies and methodology used in the graph for the Peer Group Index provides a better comparison than other indices available. The Peer Group Index consists of ArvinMeritor, Inc., Caterpillar Inc., Cummins Inc., Dana Corp., Deere & Co., Eaton Corp., Ingersoll-Rand Co. Ltd., Navistar International Corp., and Oshkosh Truck Corp. The comparison assumes that $100 was invested December 31, 2002 in the Company’s common stock and in the stated indices and assumes reinvestment of dividends.

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.

                Consolidated net sales and revenue were $15.22 billion in 2007 and $16.45 billion in 2006. Current year results reflect strong demand for the Company’s high-quality trucks in all markets outside the U.S. and Canada, and continued global growth in aftermarket parts and financial services. Financial Services revenues increased to $1.19 billion in 2007 from $.95 billion in 2006.

                PACCAR achieved net income of $1.23 billion ($3.29 per diluted share) in 2007, the second best result in the Company’s 102 year history. Solid results were achieved in the Truck and Other businesses from strong growth in revenue, increased margins and on-going cost control in the Company’s foreign operations, offset by lower truck sales and margins in the U.S. and Canada. Financial Services income before taxes increased 15% to a record $284.1 million compared to $247.4 million in 2006 as a result of strong asset growth and stable finance margins.

                Research and development expenditures were $255.5 million in 2007, an increase of 57% from $163.1 million in 2006 due to increased vehicle and engine development programs.

                Selling, general and administrative (SG&A) expense for Truck and Other increased to $491.4 million in 2007 compared to $457.3 million in 2006. This was due to expanded sales and higher production levels in the Company’s foreign operations and the translation of stronger foreign currencies, somewhat offset by lower spending in the U.S. and Canada. As a percent of revenues, SG&A expense increased to 3.5% in 2007 from 3.0% in 2006. The Company continues to implement Six Sigma initiatives and process improvements in all facets of the business.

                Investment income of $95.4 million in 2007 increased from $81.3 million in 2006 due to higher interest rates.

                The 2007 effective income tax rate was 30.4% compared to 31.2% in 2006. The lower 2007 effective income tax rate reflects a higher proportion of foreign earnings.

                The Company’s return on revenues was 8.1% in 2007 compared to 9.1% in 2006.

Truck

PACCAR’s truck segment, which includes the manufacture and distribution of trucks and related aftermarket parts, accounted for 91%, 93% and 94% of revenues in 2007, 2006 and 2005, respectively. In North America, trucks are sold under the Kenworth and Peterbilt nameplates and, in Europe, under the DAF nameplate.

	2007		2006		2005
Truck net sales and revenues	$	13,853.3	$	15,367.3	$	13,196.1
Truck income before taxes	$	1,360.0	$	1,848.8	$	1,520.2

24

The Company’s new truck deliveries are summarized below:

	2007	2006	2005
United States	44,700	82,600	71,900
Canada	8,300	12,900	10,900
U.S. and Canada	53,000	95,500	82,800
Europe	60,100	55,900	52,200
Mexico, Australia and other	20,800	15,400	13,500
Total units	133,900	166,800	148,500

2007 Compared to 2006:

PACCAR’s worldwide truck sales and revenues were $13.85 billion in 2007 compared to $15.37 billion in 2006 due to lower demand for the Company’s trucks in the U.S. and Canada, somewhat offset by higher demand for trucks in all other markets and higher global demand for related aftermarket parts. The impact of a weaker U.S. dollar relative to the Company’s other currencies (primarily the euro) increased revenues and pretax profit by approximately $590 million and $90 million, respectively.

                Truck income before taxes was $1.36 billion compared to $1.85 billion in 2006. In the U.S. and Canada, Peterbilt and Kenworth delivered 53,000 heavy and medium-duty trucks during 2007, a decrease of 45% from 2006, due to the lower truck market. The Class 8 market decreased to 175,800 units in 2007 from a record 322,500 units in 2006, reflecting a 2006 pre-buy and a slowdown in the housing and automotive sectors. PACCAR’s market share increased to 26.4% in 2007 from 25.3% in 2006. The medium-duty market decreased 21% to 85,000 units.

                In Europe, DAF trucks delivered 60,100 units during 2007, an 8% increase over 2006. The 15 tonne and above truck market in Western and Central Europe improved to 340,000 units, a 10% increase from 2006 levels. DAF’s 2007 market share of the 15 tonne and above market was 13.9% compared to 14.3% in 2006. DAF market share in the 6 to 15 tonne market was 8.3% in 2007 and 9.2% in 2006. Truck and parts sales in Europe represented 46% of PACCAR’s total truck segment net sales and revenues in 2007 compared to 28% in 2006.

                Truck unit deliveries in Mexico, Australia and other countries outside the Company’s primary markets increased 35%. Deliveries to customers in South America, Africa and Asia are sold through PACCAR International, the Company’s international sales division. Combined truck and parts sales in these markets accounted for 16% of truck segment sales and 19% of truck segment profit.

                PACCAR’s worldwide aftermarket parts revenues were $2.29 billion in 2007, an increase of 18% compared to $1.94 billion in 2006. Aftermarket parts sales increased in all major markets from a growing truck population, expansion of parts distribution centers and focused sales efforts.

                Truck segment gross margin as a percentage of net sales and revenues was 14.7% in 2007 and 15.7% in 2006. Improved operating efficiencies and strong demand for the Company’s products outside the U.S. and Canada were dampened by a weak truck market in the U.S. and Canada. Higher material costs from suppliers, including the impacts of higher crude oil, copper, steel and other commodities negatively impacted truck margins.

2006 Compared to 2005:

PACCAR’s worldwide truck sales and revenues increased to $15.37 billion in 2006 due to high demand for the Company’s trucks and related aftermarket parts in all major markets.

                Truck income before taxes was $1.85 billion compared to $1.52 billion in 2005. The increase from the prior year was due to higher production rates, growing aftermarket part sales and improved truck margins.

                In the U.S. and Canada, Peterbilt and Kenworth delivered 95,500 medium and heavy trucks during 2006, an increase of 15% over 2005 due to overall market growth and increased market share. The Class 8 market increased 12% to 322,500 units in 2006 from 287,500 in 2005. PACCAR’s market share increased to 25.3% in 2006 from 23.1% in 2005. The total medium-duty market increased 3% to 107,000 units.

                In Europe, DAF trucks delivered 55,900 units during 2006, an increase of 7% over 2005. The 15 tonne and above truck market improved to 308,900 units, a 7% increase from 2005 levels. DAF increased its share of the 15 tonne and above market to 14.3% in 2006 from 13.6% in 2005. DAF market share in the 6 to 15 tonne market was 9.2% for 2006 and 2005.

                Truck unit deliveries in Mexico, Australia and other countries outside the Company’s primary markets increased 14%. Combined truck and parts sales in these markets accounted for 10% of total truck segment sales and 9% of truck segment profit in 2006.

25

                PACCAR’s worldwide aftermarket parts revenues of $1.94 billion increased from 2005 due to a growing truck population and systems integration with dealers.

                Truck segment gross margin as a percentage of net sales and revenues improved to 15.7% in 2006 from 15.4% in 2005 as a result of improved operating efficiencies and strong demand for the Company’s products.

Truck Outlook

Continued economic softness in the U.S. and Canada is currently forecast to dampen demand for heavy-duty trucks for at least the first half of 2008. Industry retail sales are expected to remain level to slightly higher than 2007 at 175,000–215,000 trucks. Western and Central European heavy-duty registrations for 2008 are projected to remain strong at 330,000–350,000 units. Demand for the Company’s products in Mexico, Australia and international markets is expected to remain strong.

Financial Services

The Financial Services segment, which includes wholly owned subsidiaries in North America, Europe and Australia, derives its earnings primarily from financing or leasing PACCAR products. Over the last ten years, the asset portfolio and income before taxes have grown at a compound annual rate of 14%.

	2007		2006		2005
Financial Services:
Average earning assets	$	10,158.0	$	8,746.0	$	7,389.0
Revenues	1,191.3		950.8		759.0
Income before taxes	284.1		247.4		199.9

2007 Compared to 2006:

PACCAR Financial Services (PFS) revenues increased 25% to $1.19 billion due to higher earning assets worldwide and higher interest rates. New business volume was $3.94 billion in 2007 compared to $4.24 billion in 2006. PFS provided loan and lease financing for 29% of PACCAR new trucks delivered in 2007 compared to 25% in 2006.

                Income before taxes increased 15% to a record $284.1 million from $247.4 million in 2006. This improvement was primarily due to higher finance gross profit, partly offset by an increase in selling, general and administrative expenses to support business growth and a higher provision for losses on receivables. The increase in finance gross profit was due to higher asset levels and higher interest rates, offset partly by a higher cost of debt.

                Net portfolio charge-offs were $25.8 million compared to $13.9 million in 2006 due to higher charge-offs in the U.S. and Canada. At December 31, 2007, the earning asset portfolio quality was excellent with the percentage of accounts 30+ days past-due at 2.0%, up from 1.2% at the end of 2006, primarily due to increased past due accounts in the U.S. and Canada.

                During the year, PFS expanded its financing operations into Poland and now operates in 18 countries worldwide.

2006 Compared to 2005:

PACCAR Financial Services revenues increased 25% to $950.8 million due to higher earning assets worldwide and higher interest rates. New business volume was a record $4.24 billion, up 14% on higher truck sales levels and solid market share.

                Income before taxes increased 24% to a record $247.4 million from $199.9 million in 2005. This improvement was primarily due to higher finance gross profit and lower credit losses, partly offset by an increase in selling, general and administrative expenses to support business growth. The increase in finance gross profit was due to higher asset levels and higher interest rates, offset partly by a higher cost of debt. The lower provision for losses resulted from lower net portfolio charge-offs.

Financial Services Outlook

The outlook for the Financial Services segment is principally dependent on the generation of new business volume and the related spread between the asset yields and the borrowing costs on new business, as well as the level of credit losses experienced. Assets in the U.S. and Canada are not likely to increase until the new truck market recovers. Asset growth is likely in Europe due to an expected increase in DAF truck deliveries due to a strong market.

                The segment is exposed to reduced liquidity in the public debt markets. PFS does not anticipate the impact of reduced liquidity to materially impact its ability to generate new business volume.

                The segment continues to be impacted by the risk that serious economic weakness in North America and higher fuel costs may continue to exert negative pressure on the profit margins of truck operators and result in higher past-due accounts and increased repossessions.

26

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 2007, 2006 and 2005.

LIQUIDITY ANDCAPITALRESOURCES:

	2007		2006		2005
Cash and cash equivalents	$	1,858.1	$	1,852.5	$	1,698.9
Marketable debt securities	778.5		821.7		591.4
	$	2,636.6	$	2,674.2	$	2,290.3

                The Company’s total cash and marketable debt securities decreased $37.6 million in 2007. Cash provided by operations of $2,055.4 million was used primarily to pay dividends of $736.7 million, make capital additions totaling $425.7 million and repurchase PACCAR stock for $360.5 million. Cash required to originate new loans and leases was funded by repayments of existing loans and leases as well as Financial Services borrowings.

                The Company has line of credit arrangements of $3.08 billion. The unused portion of these credit lines was $3.04 billion at December 31, 2007. Included in these arrangements is a $2.7 billion bank facility, of which $1.7 billion matures in 2008 and $1.0 billion matures in 2012 and is primarily maintained to provide backup liquidity for commercial paper borrowings of the financial services companies.

                During the second half of 2007, PACCAR’s strong cash position and credit ratings enabled PFS to meet its funding requirements despite a decline in liquidity in the public debt markets. The Company believes its strong liquidity position and AA- investment grade credit rating will continue to provide financial stability and access to public debt markets at competitive interest rates.

                In October 2007, PACCAR’s Board of Directors approved the repurchase of $300 million of the Company’s common stock.

Truck and Other

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. Long-term debt was $23.6 million at December 31, 2007.

                Expenditures for property, plant and equipment in 2007 totaled a record $425.7 million compared to $312.0 million in 2006. Major capital projects included the substantial completion of construction of a new parts distribution center in Hungary, completion of a parts distribution facility in Oklahoma and the completion of a new engine test facility at DAF in the Netherlands. In addition, the Company made significant investments related to new product development and plant capacity. Over the last ten years, the Company’s combined investments in worldwide capital projects and research and development totaled $3.33 billion.

                Spending for capital investments and research and development in 2008 is expected to increase from 2007 levels. In 2008, major projects will include the start of construction on an engine production and technology facility in Mississippi and continued focus on engine development, new product introductions and manufacturing efficiency improvements.

27

Financial Services

The Company funds its financial services activities primarily from collections on existing finance receivables and borrowings in the capital markets. An additional source of funds is loans from other PACCAR companies.

                The primary sources of borrowings in the capital market are commercial paper and medium-term notes issued in the public markets and, to a lesser extent, bank loans. The majority of the medium-term notes are issued by PACCAR’s largest financial services subsidiary, PACCAR Financial Corp. (PFC). PFC filed a shelf registration under the Securities Act of 1933 in 2006. The registration expires in 2009 and does not limit the principal amount of debt securities that may be issued during the period.

                In June 2007, PACCAR’s European finance subsidiary, PACCAR Financial Europe, renewed and increased the registration of a €1.2 billion medium-term note program with the London Stock Exchange. On December 31, 2007, €448 million remained available for issuance. This program is renewable annually through the filing of a new prospectus.

                To reduce exposure to fluctuations in interest rates, the Financial Services companies pursue a policy of structuring borrowings with interest-rate characteristics similar to the assets being funded. As part of this policy, the companies use interest-rate contracts. The permitted types of interest-rate contracts and transaction limits have been established by the Company’s senior management, who receive periodic reports on the contracts outstanding.

                PACCAR believes its Financial Services companies will be able to continue funding receivables, servicing debt and paying dividends through internally generated funds, access to public and private debt markets and lines of credit.

Commitments

The following summarizes the Company’s contractual cash commitments at December 31, 2007:

	Maturity
	Within		More than
	One Year		One Year		Total
Borrowings	$	4,836.8	$	3,039.0	$	7,875.8
Operating leases	28.0		42.1		70.1
Purchase obligations	261.0		50.5		311.5
Other obligations	5.5		29.3		34.8
Total	$	5,131.3	$	3,160.9	$	8,292.2

                The Company had $8.29 billion of cash commitments, substantially all of which mature within three years. Of the total cash commitments for borrowings, $7.86 billion were related to the Financial Services segment. As described in Note K of the consolidated financial statements, borrowings consist primarily of term debt and commercial paper issued by the Financial Services segment. The Company expects to fund its maturing Financial Services debt obligations principally from funds provided by collections from customers on loans and lease contracts, as well as from the proceeds of commercial paper and medium-term note borrowings. Purchase obligations are the Company’s contractual commitment to acquire future production inventory. Other obligations include deferred cash compensation.

28

                The Company’s other commitments include the following at December 31, 2007:

	Commitment Expiration
	Within		More than
	One Year		One Year		Total
Letters of credit	$	17.4	$	18.0	$	35.4
Loan and lease commitments	145.1				145.1
Equipment acquisition commitments	43.4		8.1		51.5
Residual value guarantees	115.6		212.8		328.4
Total	$	321.5	$	238.9	$	560.4

                Loan and lease commitments are for funding new retail loan and lease contracts. Equipment acquisition commitments require the Company, under specified circumstances, to purchase equipment. Residual value guarantees represent the Company’s commitment to acquire trucks at a guaranteed value if the customer decides to return the truck at a specified date in the future.

IMPACT OF ENVIRONMENTAL MATTERS:

The Company, its competitors and industry in general are subject to various domestic and foreign requirements relating to the environment. The Company believes its policies, practices and procedures are designed to prevent unreasonable risk of environmental damage and that its handling, use and disposal of hazardous or toxic substances have been in accordance with environmental laws and regulations enacted at the time such use and disposal occurred. Expenditures related to environmental activities in 2007, 2006 and 2005 were immaterial.

                The Company is involved in various stages of investigations and cleanup actions in different countries related to environmental matters. In certain of these matters, the Company has been designated as a “potentially responsible party” by domestic and foreign environmental agencies. The Company has provided an accrual for the estimated costs to investigate and complete cleanup actions where it is probable that the Company will incur such costs in the future. Management expects that these matters will not have a significant effect on the Company’s consolidated cash flow, liquidity or financial condition.

CRITICAL ACCOUNTING POLICIES:

In the preparation of the Company’s financial statements, in accordance with U.S. generally accepted accounting principles, management uses estimates and makes judgments and assumptions that affect asset and liability values and the amounts reported as income and expense during the periods presented. The following are accounting policies which, in the opinion of management, are particularly sensitive and which, if actual results are different, may have a material impact on the financial statements.

Operating Leases

The accounting for trucks sold pursuant to agreements accounted for as operating leases is discussed in Notes A and G of the consolidated financial statements. In determining its estimate of the residual value of such vehicles, the Company considers 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 trucks at the end of the term of the agreement differs from the Company’s estimate, a gain or loss will result. The Company believes its residual-setting policies are appropriate; however, 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.

29

Allowance for Credit Losses

The Company determines the allowance for credit losses on financial services receivables based on a combination of historical information and current market conditions. This determination is dependent on estimates, including 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 believes its reserve-setting policies adequately take into account the known risks inherent in the financial services portfolio. If there are significant variations in the actual results from those estimates, the provision for credit losses and operating earnings may be materially impacted.

Product Warranty

The expenses related to product warranty are estimated and recorded at the time products are sold based on historical and current data and reasonable expectations for the future regarding the frequency and cost of warranty claims. Management believes that the warranty reserve is appropriate and takes actions to minimize warranty costs through quality-improvement programs; however, actual claims incurred could materially differ from the estimated amounts and require adjustments to the reserve.

Pension and Other Postretirement Benefits

The Company’s accounting for employee pension and other postretirement benefit costs and obligations is based on management assumptions about the future used by actuaries to estimate net costs and liabilities. These assumptions include discount rates, long-term rates of return on plan assets, health care cost trends, inflation rates, retirement rates, mortality rates and other factors. Management bases these assumptions on historical results, the current environment and reasonable expectations of future events.

                The discount rate for each plan is based on market interest rates of high-quality corporate bonds with a maturity profile that matches the timing of the projected benefit payments of the plans. Changes in the discount rate affect the valuation of the plan benefits obligation and funded status of the plans.

                The long-term rate of return on plan assets is based on projected returns for each asset class and relative weighting of those asset classes in the plans.

                Actual results that differ from these assumptions are accumulated and amortized into expense over future periods. While management believes that the assumptions used are appropriate, significant differences in actual experience or significant changes in assumptions would affect pension and other postretirement benefit costs and obligations and the balance sheet funded status of the plans.

FORWARD-LOOKING STATEMENTS:

Certain information presented in this report contains forward-looking statements made pursuant to the Private Securities Litigation Reform Act of 1995, which are subject to risks and uncertainties that may affect actual results.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2007, 2006 and 2005 (currencies in millions)

A.            SIGNIFICANT ACCOUNTING POLICIES

Description of Operations: PACCAR Inc (the Company or PACCAR) is a multinational company operating in two segments: (1) the manufacture and distribution of light-, medium- and heavy-duty commercial trucks and related aftermarket parts and (2) finance and leasing products and services provided to customers and dealers. PACCAR’s sales and revenues are derived primarily from North America and Europe. The Company also operates in Australia and sells trucks and parts outside its primary markets to customers in Asia, Africa and South America.

                Principles of Consolidation: The consolidated financial statements include the accounts of the Company and its wholly owned domestic and foreign subsidiaries. All significant intercompany accounts and transactions are eliminated in consolidation.

                Use of Estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

                Cash and Cash Equivalents: Cash equivalents consist of liquid investments with a maturity at date of purchase of three months or less.

                Trade and Other Receivables: The Company’s trade and other receivables are included at cost on the balance sheet, net of allowances.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2007, 2006 and 2005 (currencies in millions except per share amounts)

                Long-lived Assets, Goodwill and Other Intangible Assets: The Company evaluates the carrying value of long-lived assets (including property and equipment, goodwill and other intangible assets) when events and circumstances warrant such a review. Goodwill is also tested for impairment on an annual basis. There were no impairment charges during the three years ended December 31, 2007.

                Revenue Recognition: Substantially all sales and revenues of trucks and related aftermarket parts are recorded by the Company when products are shipped to dealers or customers, except for certain truck shipments that are subject to a residual value guarantee to the customer. Revenues related to these shipments are recognized on a straight-line basis over the guarantee period (see Note G). At the time certain truck and parts sales to a dealer are recognized, the Company records an estimate of the future sales incentive costs related to such sales. The estimate is based on historical data and announced incentive programs.

                Interest income from finance and other receivables is recognized using the interest method. Certain loan origination costs are deferred and amortized to interest income. For operating leases, rental revenue is recognized on a straight-line basis over the lease term. Recognition of interest income and rental revenue is suspended when management determines that collection is not probable (generally after 90 days past the contractual due date). Recognition is resumed if the receivable becomes contractually current and the collection of amounts is again considered probable.

                Foreign Currency Translation: For most of PACCAR’s foreign subsidiaries, the local currency is the functional currency. All assets and liabilities are translated at year-end exchange rates and all income statement amounts are translated at the weighted average rates for the period. Translation adjustments are recorded in accumulated other comprehensive income (loss), a component of stockholders’ equity.

                PACCAR uses the U.S. dollar as the functional currency for its Mexican subsidiaries. Accordingly, inventories, cost of sales, property, plant and equipment, and depreciation are remeasured at historical rates. Resulting gains and losses are included in net income.

                Earnings per Share: Diluted earnings per share are based on the weighted average number of basic shares outstanding during the year, adjusted for the dilutive effects of stock-based compensation awards under the treasury stock method.

                New Accounting Pronouncements: The Company adopted FASB Statement No. 158, Employers’ Accounting for Defined Benefit Pension and Other Retirement Plans (FAS 158) effective December 31, 2006. FAS 158 requires an employer to recognize the funded status of each of its defined benefit post-retirement plans as an asset or liability and to recognize changes in funded status as a component of accumulated other comprehensive income. Upon adoption, total assets were reduced by $114.7, total liabilities were increased by $45.5 and stockholders’ equity was reduced by $160.5, net of tax.

                The Company adopted FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes (FIN 48) effective January 1, 2007 with no significant effect on the Company’s consolidated financial statements. See Note M for further information concerning income taxes.

                In September 2006, the FASB issued Statement No. 157, Fair Value Measurements (FAS 157). FAS 157 defines fair value and expands disclosures about fair value measurements and is effective January 1, 2008. Adoption of FAS 157 is not expected to have a material effect on the Company’s consolidated financial statements.

                In February 2007, the FASB issued Statement No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (FAS 159). This Statement, which is effective January 1, 2008 for PACCAR, permits entities to measure most financial instruments at fair value if desired and requires that unrealized gains and losses on items for which the option has been elected to be reported in earnings. The Company does not expect adoption of FAS 159 to have a material effect on its consolidated financial statements.

                Reclassifications: Certain prior-year amounts have been reclassified to conform to the 2007 presentation.

b.investments inmarketablesecurities

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 income. Gross realized and unrealized gains and losses were not significant for any of the three years ended December 31, 2007.

                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.

                Marketable debt securities consisted of the following at December 31:

	amortized		fair
2007	cost		value
U.S. tax-exempt securities	$	554.0	$	558.4
Non U.S. corporate securities	113.7		113.0

U.S. government securities	59.4		58.5
Other debt securities	12.2		12.3
	$	823.9	$	821.7

                Contractual maturities at December 31, 2007, were as follows:

	amortized		fair
Maturities:	cost		value
Within one year	$	90.2	$	90.2
One to five years	609.5		612.5
Five to ten years	1.1		1.1
10 or more years	74.6		74.7
	$	775.4	$	778.5

                Marketable debt securities included $75.8 and $128.4 of variable rate demand obligations (VRDOs) at December 31, 2007 and 2006, respectively. VRDOs are debt instruments with long-term scheduled maturities which have interest rates that reset periodically.

c.            inventories

Inventories include the following:

At December 31,	2007			2006
Finished products	$	422.7		$	365.4
Work in process and raw materials	355.0			472.1
	777.7			837.5
Less LIFO reserve	(149.4		)	(143.8		)
	$	628.3		$	693.7

                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 valued using the LIFO method comprised 40% and 53% of consolidated inventories before deducting the LIFO reserve at December 31, 2007 and 2006.

D.Financeand Other Receivables

Finance and other receivables consist primarily of receivables from loans and financing leases resulting from truck sales, loan and leasing activity. Finance and other receivables include the following:

At December 31,	2007			2006
Loans	$	4,325.9		$	4,226.7
Retail direct financing leases	2,816.7			2,322.1
Sales-type finance leases	908.1			909.2
Dealer wholesale financing	1,554.6			1,562.6
Interest and other receivables	108.9			112.1
Unearned interest:
Finance leases	(495.4		)	(421.0		)
	9,218.8			8,711.7
Less allowance for losses	(193.4		)	(169.0		)
	$	9,025.4		$	8,542.7

                Terms for substantially all finance and other receivables range up to 60 months. Annual payments due on loans beginning January 1, 2008, are $1,663.8, $1,171.0, $876.5, $530.9, $236.4 and $25.5 thereafter. Annual minimum lease payments due on finance leases beginning January 1, 2008, are $1,051.9, $930.9, $722.4, $472.6, $224.1 and $106.3 thereafter. Repayment experience indicates that some receivables will be paid prior to contract maturity, while others may be extended or revised.

                The effects of sales-type leases, dealer direct loans and wholesale financing of new trucks are shown in the consolidated statements of cash flows as operating activities since they finance the sale of company inventory. Included in Loans are dealer direct loans on the sale of new trucks of $198.2 and $220.4 as of December 31, 2007 and 2006. Estimated residual values included with finance leases amounted to $216.6 in 2007 and $173.7 in 2006.

E.Allowancefor Losses

Receivables are charged to the allowance for losses when, in the judgment of management, they are deemed uncollectible (generally upon repossession of the collateral). The provision for losses on finance, trade and other receivables is charged to income in an amount sufficient to maintain the allowance for losses at a level considered adequate to cover estimated credit losses.

                The allowance for losses on Truck and Other and Financial Services receivables is summarized as follows:

	truck			financial
	and other			services
Balance, December 31, 2004	$	12.7		$	127.4
Provision for losses	.3			40.4
Net losses	(.5		)	(19.3		)

g.            equipment on operating leases

The Company leases equipment under operating leases to customers in the financial services segment. In addition, in the truck segment, equipment sold to customers in Europe subject to a residual value guarantee (RVG) is accounted for as operating leases. Equipment is recorded at cost and is depreciated on the straight-line basis to the lower of the estimated residual value or guarantee value. Lease and guarantee periods generally range from three to seven years. Estimated useful lives of the equipment range from five to ten years. The Company reviews residual values of equipment on operating leases periodically to determine that recorded amounts are appropriate.

Truck and Other:

Equipment on operating leases is as follows:

At December 31,	2007			2006
Equipment on lease	$	678.8		$	589.7
Less allowance for depreciation	(189.6		)	(171.5		)
	$	489.2		$	418.2

                When the equipment is sold subject to an RVG, the full sales price is received from the customer. A liability is established for the residual value obligation with the remainder of the proceeds recorded as deferred lease revenue. These amounts are summarized below:

At December 31,	2007		2006
Deferred lease revenues	$	211.0	$	192.4
Residual value guarantee	328.4		285.1

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. PACCAR periodically assesses the adequacy of its recorded liabilities and adjusts them as appropriate to reflect actual experience.

J.             Borrowingsandcreditarrangements

Truck and other long-term debt consists of non-interest bearing notes, which amounted to $23.6 in 2007 and $20.2 in 2006. These notes mature in 2011.

                Financial Services borrowings include the following at December 31:

	effective
	rate		2007		2006
Commercial paper	5.2	%	$	4,096.4	$	4,200.6
Bank loans	8.5	%	10.4		22.0
			$	4,106.8	$	4,222.6
Term debt:
Fixed rate	9.2	%	$	20.8	$	48.3
Floating rate	4.8	%	3,724.6		2,988.9
			$	3,745.4	$	3,037.2

                The effective rate is the weighted average rate as of December 31, 2007, and includes the effects of interest-rate contracts.  Annual maturities of term debt beginning January 1, 2008, are $729.9, $2,212.6, $794.9 and $8.0.

                Interest paid on borrowings was $339.0, $281.6 and $204.0 in 2007, 2006 and 2005. The weighted average interest rate on consolidated commercial paper and bank loans was 5.2%, 4.8% and 4.0% at December 31, 2007, 2006 and 2005.

                The primary sources of borrowings are commercial paper and medium-term notes issued in the public markets. The medium-term notes are issued by PACCAR Financial Corp. (PFC) and PACCAR Financial Europe (PFE). PFC filed a shelf registration under the Securities Act of 1933 in 2006. The registration expires in 2009 and does not limit the principal amount of debt securities that may be issued during the period.

                In June 2007, PFE renewed and increased the registration of a €1,200 medium-term note program with the London Stock Exchange. On December 31, 2007, €448 of debt remained available for issuance under this program.

                The Company has line of credit arrangements of $3,076. Included in these arrangements is a $2,700 bank facility, of which $1,700 matures in 2008 and $1,000 in 2012. PACCAR intends to replace these credit facilities as they expire with facilities of similar amounts. The unused portion of these credit lines was $3,042 at December 31, 2007, of which the majority is maintained to provide backup liquidity for commercial paper borrowings. Compensating balances are not required on the lines, and service fees are immaterial.

k.            leases

The Company leases certain facilities, computer equipment and aircraft under operating leases. Leases expire at various dates through the year 2017.

                Annual minimum rent payments under non-cancelable operating leases having initial or remaining terms in excess of one year at January 1, 2008, are $27.9, $17.7, $12.1, $7.3, $2.7 and $2.3 thereafter.

                Total rental expenses under all leases amounted to $41.1, $41.4 and $42.3 for 2007, 2006 and 2005.

l.            employee benefit plans

PACCAR has several defined benefit pension plans, which cover a majority of its employees.

                The Company evaluates its actuarial assumptions on an annual basis and considers changes based upon market conditions and other factors.

                The Company funds its pensions in accordance with applicable employee benefit and tax laws. The Company contributed $13.8 to its pension plans in 2007 and $149.7 in 2006. The Company expects to contribute in the range of $15.0 to $30.0 to its pension plans in 2008, of which $15.3 is estimated to satisfy minimum funding requirements. Annual benefits expected to be paid beginning January 1, 2008, are $45.0, $47.4, $51.4, $57.0, $63.2, and for the five years thereafter, a total of $386.4.

                Plan assets are invested in a diversified mix of equity and debt securities through professional investment managers with the objective to achieve targeted risk adjusted returns and maintain liquidity sufficient to fund current benefit payments. Allocation of plan assets may change over time based upon investment manager determination of the relative attractiveness of equity and debt securities. The Company periodically assesses allocation of plan assets by investment type and evaluates external sources of information regarding the long-term historical returns and expected future returns for each investment type.

                The following information details the allocation of plan assets by investment type:

			Actual

                The Company has certain defined contribution benefit plans whereby it generally matches employee contributions of 2% to 5% of base wages. The majority of participants in these plans are non-union employees located in the United States. Expenses for these plans were $22.6, $22.1 and $20.6 in 2007, 2006 and 2005.

                The Company also provides coverage of approximately 50% of medical costs for the majority of its
U.S. employees from retirement until age 65 as well as a death benefit.

The Company adopted FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes (FIN 48) effective January 1, 2007. At adoption, the Company had $54.3 of unrecognized tax benefits and $25.0 of related assets.

                A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

Balance at January 1, 2007	$	54.3
Additions based on tax positions and settlements related to the current year	11.4
Reductions for tax positions of prior years	(2.9		)
Lapse of statute of limitations	(4.9		)
Balance at December 31, 2007	$	57.9

                Additionally, the Company had $30.6 of related assets at December 31, 2007. All of the unrecognized tax benefits and related assets would impact the effective tax rate if recognized. The Company does not currently anticipate any significant changes to its unrecognized tax benefits during the next 12 months.

                Interest and penalties are classified as income taxes in the accompanying statements of income and were not significant during any of the three years ended December 31, 2007. Amounts accrued for the payment of penalties and interest at December 31, 2007, and 2006 were also not significant.

                The United States Internal Revenue Service has completed examinations of the Company’s tax returns for all years through 2003. Examinations of the Company’s tax returns for other major jurisdictions have been completed for years ranging from 2001 through 2007.

N.Stockholders’ equity

Stockholder Rights Plan: The plan provides one right for each share of PACCAR common stock outstanding. Rights become exercisable if a person publicly announces the intention to acquire 15% or more of PACCAR’s common stock or if a person (Acquiror) acquires such amount of common stock. In all cases, rights held by the Acquiror are not exercisable. When exercisable, each right entitles the holder to purchase for two hundred dollars a fractional share of Series A Junior Participating Preferred Stock. Each fractional preferred share has dividend, liquidation and voting rights which are no less than those for a share of common stock. Under certain circumstances, the rights may become exercisable for shares of PACCAR common stock or common stock of the Acquiror having a market value equal to twice the exercise price of the right. Also under certain circumstances, the Board of Directors may exchange exercisable rights, in whole or in part, for one share of PACCAR common stock per right. The rights, which expire in the year 2009, may be redeemed at one cent per right, subject to certain conditions. For this plan, 50,000 preferred shares are reserved for issuance. No shares have been issued.

Derivative financial instruments are used as hedges to manage exposures to fluctuations in interest rates and foreign currency exchange rates. PACCAR’s policies prohibit the use of derivatives for speculation or trading. The Company documents its hedge objectives, procedures and accounting treatment at the inception of and during the term of each hedge. Exposure limits and minimum credit ratings are used to minimize the risks of counterparty default, and the Company had no material exposures to default at December 31, 2007.

                Interest-Rate Contracts: The Company enters into various interest-rate contracts, including interest-rate swaps and cap agreements. Interest-rate contracts generally involve the exchange of fixed and floating rate interest payments. These contracts are used to manage exposures to fluctuations in interest rates. Net amounts paid or received are reflected as adjustments to interest expense. At December 31, 2007, the notional amount of the Company’s interest-rate contracts totaled $5,355.6, with amounts expiring annually over the next six years. The notional amount is used to measure the volume of these contracts and does not represent exposure to credit loss. In the event of default by a counterparty, the risk in these transactions is the cost of replacing the interest-rate contract at current market rates. The total fair value of all interest-rate contracts amounted to an asset of $18.9 and a liability of $53.6 at December 31, 2007. Fair values at December 31, 2006 amounted to an asset of $36.0 and a liability of $17.3.

                Notional maturities for all interest-rate contracts for the six years beginning January 1, 2008, are $1,545.6, $1,737.8, $1,355.4, $612.4, $100.9 and $3.5. 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. Cross currency interest-rate swaps are also used to hedge foreign currency exposure in addition to modifying the interest-rate characteristics of debt.

                Foreign Currency Exchange Contracts: PACCAR enters into foreign currency exchange contracts to hedge certain anticipated transactions and borrowings denominated in foreign currencies, particularly the Canadian dollar, the euro, the British pound and the Mexican peso. PACCAR had net foreign currency exchange contracts outstanding amounting to $494.9 and $279.3 U.S. dollars at December 31, 2007 and 2006, respectively. The net fair value of these contracts was an asset of $19.2 and a liability of $.3 at December 31, 2007. Fair values at December 31, 2006 amounted to an asset of $2.0 and a liability of $.5. Foreign currency exchange contracts mature within one year.

                Derivative assets are included in the consolidated balance sheets in Truck and Other “Deferred taxes and other current assets” and Financial Services “Other assets.” Derivative liabilities are included in Truck and Other “Accounts payable and accrued expenses” and in Financial Services “Accounts payable, accrued expenses and other.”

                Substantially all of the Company’s interest-rate contracts and foreign currency exchange contracts have been designated as cash flow hedges. The Company uses regression and the change in variable cash flow methods to assess and measure effectiveness of interest-rate contracts. For foreign currency exchange contracts, the Company performs quarterly assessments to ensure that critical terms continue to match. Gains or losses on the effective portion of derivatives designated and qualifying as cash flow hedges that arise from changes in fair value are initially reported in other comprehensive income. Gains or losses on the ineffective portion of cash flow hedges are recognized currently in earnings and were immaterial for each of the three years ended December 31, 2007.

                Amounts in accumulated other comprehensive income are reclassified into net income in the same period in which the hedged transaction affects earnings. Of the accumulated net loss included in other comprehensive income as of December 31, 2007, $12.3, net of taxes, is expected to be reclassified to interest expense or cost of sales in 2008. 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. Net realized gains and losses from interest-rate contracts are recognized as an adjustment to interest expense. 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.

P.            stock compensation plans

PACCAR has certain plans under which officers and key employees may be granted options to purchase shares of the Company’s authorized but unissued common stock. Non-employee directors and certain officers may be granted restricted shares of the Company’s common stock. The maximum number of shares of the Company’s common stock authorized for issuance under these plans is 46.7 million, and as of December 31, 2007, the maximum number of shares available for future grants was 19.5 million. Options outstanding under these plans were granted with exercise prices equal to the fair market value of the Company’s common stock at the date of grant. Options expire no later than 10 years from the grant date and generally vest within three years. Stock option activity is summarized below:

			average

*Weighted Average

                Realized tax benefits for 2007 of $13.6 and 2006 of $15.3 related to the excess of deductible amounts over compensation costs recognized have been classified as a financing cash flow. Stock based compensation expense was $12.3, $10.0 and $7.5 in 2007, 2006 and 2005 respectively. As of December 31, 2007, there was $7.5 of unamortized compensation cost related to unvested stock options, which is expected to be recognized over a remaining weighted-average vesting period of 1.5 years. Unamortized compensation cost at December 31, 2007 related to unvested restricted stock awards was $2.8, which is expected to be recognized over a remaining weighted-average vesting period of 1.1 years.

                The estimated fair value of stock options granted during 2007, 2006 and 2005 was $10.10, $7.96 and $9.45 per share. These amounts were determined using the Black-Scholes-Merton option-pricing model, which values options based on the stock price at the grant date and the following assumptions:

	2007		2006		2005
Risk-free interest rate	4.80	%	4.44	%	3.73	%
Expected volatility	30	%	34	%	39	%
Expected dividend yield	4.0	%	4.0	%	3.2	%
Expected term	5 years		5 years		5 years

                The fair value of restricted stock awards was determined based on the stock price at the award date.  Compensation expense related to these awards is recognized over the requisite service period.

                Diluted Earnings Per Share: The following table shows additional shares added to weighted average basic shares outstanding to calculate diluted earnings per share. These additional shares primarily represent the effect of stock options.

At December 31:	2007	2006	2005

Q.            fair valuesoffinancial instruments

The Company used the following methods and assumptions to determine the fair values of its financial instruments:

                Cash and Cash Equivalents: Carrying amounts approximate fair value.

                Marketable Securities: Amounts are carried at fair value, based on quoted market prices (see Note B).

                Financial Services Net Receivables: For floating-rate loans, wholesale financings, and interest and other receivables, fair values approximate carrying values. For fixed-rate loans, fair values are estimated using discounted cash flow analysis based on current rates for comparable loans. Finance lease receivables and related loss provisions have been excluded from the accompanying table.

                Derivative Instruments: Derivative instruments, including interest rate contracts and foreign currency exchange contracts, are carried at fair value. Fair values are based on quoted market prices or pricing models using current market rates and represent the amounts that the Company would receive or pay to terminate the contracts.

                Debt: The carrying amounts of fixed-rate long-term debt, financial services term debt, commercial paper, short-term bank borrowings and floating-rate, long-term debt approximate fair value.

                Trade Receivables and Payables: Carrying amounts approximate fair value.

                Financial services fixed-rate loans that are not carried at approximate fair value are as follows at December 31:

	carrying		fair
	amount		value
2007	$	3,602.6	$	3,562.7
2006	3,420.8		3,335.2

R.            commitments and contingencies

The Company is involved in various stages of investigations and cleanup actions in different countries related to environmental matters. In certain of these matters, the Company has been designated as a “potentially responsible party” by domestic and foreign environmental agencies. The Company has an accrual to provide for the estimated costs to investigate and complete cleanup actions where it is probable that the Company will incur such costs in the future. Expenditures related to environmental activities in 2007, 2006 and 2005 were not significant.

                While the timing and amount of the ultimate costs associated with future environmental cleanup cannot be determined, management expects that these matters will not have a significant effect on the Company’s consolidated financial position.

                At December 31, 2007, PACCAR had standby letters of credit of $35.4, which guarantee various insurance and financing activities. The Company is committed, under specific circumstances, to purchase equipment at a cost of $43.4 in 2008 and $8.1 in 2009. At December 31, 2007, PACCAR’s financial services companies, in the normal course of business, had outstanding commitments to fund new loan and lease transactions amounting to $145.1. The commitments generally expire in 90 days. The Company had other commitments, primarily to purchase production inventory, amounting to $266.5 in 2008 and $79.8 thereafter.

                PACCAR is a defendant in various 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 proceedings and contingent liabilities will have a material effect on the consolidated financial statements.

s.            segment and related information

PACCAR operates in two principal segments, Truck and Financial Services.

                The Truck segment includes the manufacture of trucks and the distribution of related aftermarket parts, both of which are sold through a network of independent dealers. This segment derives a large proportion of its revenues and operating profits from operations in North America and Europe.

                The Financial Services segment is composed of finance and leasing products and services provided to truck customers and dealers. Revenues are primarily generated from operations in North America and Europe.

                Included in All Other is PACCAR’s industrial winch manufacturing business. Also within this category are other sales, income and expenses not attributable to a reportable segment, including a portion of corporate expense. Intercompany interest income on cash advances to the financial services companies is included in All Other and was $24.9, $13.1 and $15.7 for 2007, 2006 and 2005. Geographic revenues from external customers are presented based on the country of the customer.

                PACCAR evaluates the performance of its Truck segment 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.

Management’s report on internal control over
financial reporting

The management of PACCAR Inc (the Company) is responsible for establishing and maintaining satisfactory internal control over financial reporting. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

                Internal control over financial reporting may not prevent or detect misstatements because of its inherent limitations. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

                Management assessed the Company’s internal control over financial reporting as of December 31, 2007, based on criteria for effective internal control over financial reporting described in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, we concluded that the Company maintained effective internal control over financial reporting as of December 31, 2007.

                Management’s assessment of the effectiveness of the Company’s internal control over financial reporting has been audited by Ernst & Young LLP, an Independent Registered Public Accounting Firm, as stated in their report.

Mark C. Pigott

Chairman and Chief Executive Officer

report of independent registered public accounting firm on the company’s consolidated financial statements

The Board of Directors and Stockholders of PACCAR Inc

We have audited the accompanying consolidated balance sheets of PACCAR Inc as of December 31, 2007 and 2006, and the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2007. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

                We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

                In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of PACCAR Inc at December 31, 2007 and 2006, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2007, in conformity with U.S. generally accepted accounting principles.

                As discussed in Note A to the consolidated financial statements, the Company changed its method of accounting for defined benefit pension and other postretirement plans in 2006.

                We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), PACCAR Inc’s internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 14, 2008 expressed an unqualified opinion thereon.

report of independent registered public accounting firm on the company’s internal controls

The Board of Directors and Stockholders of PACCAR Inc

We have audited PACCAR Inc’s internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). PACCAR Inc’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

                We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

                A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

                Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

                In our opinion, PACCAR Inc maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007, based on the COSO criteria.

                We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets as of December 31, 2007 and 2006 and the related consolidated statements of income, stockholders’ equity, comprehensive income and cash flows for each of the three years in the period ended December 31, 2007 of PACCAR Inc and our report dated February 14, 2008 expressed an unqualified opinion thereon.

market risks and derivative instruments

(currencies in millions)

Interest Rate Risks — See Note O for a description of the Company’s hedging programs and exposure to interest rate
fluctuations. The Company measures its interest rate risk by estimating the amount by which the fair value of interest rate sensitive assets and liabilities, including derivative financial instruments, would change assuming an immediate 100 basis point increase across the yield curve as shown in the following table:

Fair Value Gains (Losses)	2007			2006
consolidated:
Assets
Cash equivalents and marketable securities	$	(9.2	)	$	(12.2	)
truck and other:
Liabilities
Fixed-rate long-term debt	.6			.6
FINANCIAL SERVICES:
Assets
Fixed-rate loans	(59.7		)	(59.6		)
Liabilities
Fixed-rate term debt	.4			.5
Interest rate swaps related to financial services debt	82.0			72.7
Total	$	14.1		$	2.0

Currency Risks — The Company enters into foreign currency exchange contracts to hedge its exposure to exchange rate fluctuations of foreign currencies, particularly the Canadian dollar, the euro, the British pound and the Mexican peso (see Note O for additional information concerning these hedges). Based on the Company’s sensitivity analysis, the potential loss in fair value for such financial instruments from a 10% unfavorable change in quoted foreign currency exchange rates would be a loss of $53.3 related to contracts outstanding at December 31, 2007, compared to a loss of $24.2 at December 31, 2006. These amounts would be largely offset by changes in the values of the underlying hedged exposures.
