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 pages 46 and 47 of the Annual Report to Stockholders for the year ended December 31, 2002 and is incorporated herein by reference.

The Company has two principal industry segments, (1) 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 distributes trucks and parts primarily through its independent dealer network. 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 Peterbilt, Kenworth, DAF and Foden nameplates. These vehicles, which are built in four plants in the United States, three in Europe and one each in Australia, Canada, and Mexico, are used worldwide for over-the-road and off-highway hauling of freight, petroleum, wood products, construction and other materials. Commercial trucks and related replacement parts comprise the largest segment of the Company’s business, accounting for 93% of total 2002 net sales and revenues.

The Company, through its Peterbilt and Kenworth Divisions, competes in the North American medium-duty (Class 6/7) markets primarily with conventional models. These medium-duty trucks are assembled at the Company’s Ste. Therese, Quebec plant and at the Company’s facility in Mexicali, Mexico. This line of business represents a small, but increasing, percentage of the Company’s North American sales. The Company competes in the European light/medium (6 to 15 metric ton) commercial vehicle market with DAF cab-over-engine trucks assembled in the United Kingdom by Leyland, one of the Company’s wholly-owned subsidiaries.

Substantially all trucks and related parts are sold to dealers, which are independent except for a small number of factory branches. 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 and Foden nameplates are marketed and distributed by foreign subsidiaries headquartered in the Netherlands and United Kingdom, respectively. A U.S. division, PACCAR International, also markets all four 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.

The Truck Segment utilizes centrally managed purchasing, information technology, engineering technical research and testing, treasury and finance functions. Certain manufacturing plants in North America and Europe produce trucks for more than one nameplate in common production facilities, while other plants produce trucks for only one nameplate, depending on various factors. Also, 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 50% in Europe to approximately 80% 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 5% of consolidated revenues. 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 for the Company 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 2002. 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% in 2002, 16% in 2001 and 12% in 2000.

There were three other principal competitors in the U.S. and Canada Class 8 truck market in 2002. The Company’s share of that market was 23.6% of retail sales in 2002. In Europe there were five other principal competitors in the commercial vehicle market in 2002, including parent companies to two competitors of the Company in the United States. The Company’s subsidiary, DAF, had a 12.0% share of the Western European heavy-duty market and a 8.6% 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.

The Peterbilt, Kenworth, DAF and Foden 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.

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

The Company had a total production backlog of $1.4 billion at the end of 2002. Within this backlog, orders scheduled for delivery within three months (90 days) are considered to be firm. The 90-day backlog approximated $1.1 billion at December 31, 2002, and $0.8 billion at December 31, 2001. Production of the year-end 2002 backlog is expected to be completed during 2003.

The number of persons employed by the Company in its truck business at December 31, 2002, was approximately 15,500.

OTHER BUSINESS

The Truck and Other businesses includes a division of the Company which manufacturers 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 less than 1% of net sales and revenues in 2002, 2001 and 2000.

The Braden, Carco, and Gearmatic trademarks and trade names are recognized internationally and play an important role in the marketing of those products. The Company has an ongoing program of trademark and trade name protection in all relevant marketing areas.

FINANCIAL SERVICES

In North America, Australia and seven Western European countries, the Company provides financing and leasing arrangements principally for its manufactured trucks through wholly-owned finance companies operating under the PACCAR Financial or PacLease trade names. 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.

PACCAR has a 49% equity ownership in DAF Financial Services (DFS) in Europe. Effective July 1, 2001, concurrent with the start-up of wholly-owned PACCAR Financial Europe in seven Western European markets, DFS ceased writing new business. At December 31, 2002 DFS had total assets of $425 million compared to $715 million at December 31, 2001. DFS will continue to service existing assets until they are liquidated in the ordinary course of business. This investment, which is recorded under the equity method, was $37 million at December 31, 2002. For DFS, operating results were insignificant for the three years ended December 31, 2002.

The Company also conducts full service leasing operations through wholly-owned subsidiaries in North America 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 managerial 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. The Company believes it is in compliance with the Act and applicable safety standards.

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, 2002, the Company employed a total of approximately 16,500 persons.

ITEM 2. PROPERTIES

The Company and its subsidiaries own and operate manufacturing plants in five U.S. states, three locations in Europe, and one each in Australia, Canada and Mexico. Several parts distribution centers, sales and service offices, and finance and administrative offices are also operated in owned or leased premises in these and other countries. Facilities for product testing and research and development are located in Skagit County, Washington and Eindhoven, 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.

Most of the Company’s manufacturing facilities increased their production levels in 2002 compared to the previous year. There is additional capacity utilization available in the Company’s North American and European facilities. The Company’s manufacturing facility in Australia operated near its productive capacity during the second half of 2002.

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

	U.S.	Canada	Australia	Mexico	Europe

ITEM 3. LEGAL PROCEEDINGS
