INDEX

PART I

PACCAR Inc (the Company or PACCAR), 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.

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 in Item 8, Note S, of this Form 10-K.

PACCAR is a multinational company operating in three principal industry segments:

PACCAR’s Other business includes the manufacturing and marketing of industrial winches.

TRUCKS

PACCAR’s trucks are marketed under the Kenworth, Peterbilt and DAF nameplates. These trucks, which are built in three plants in the United States, three in Europe and one each in Australia, Brasil, Canada and Mexico, are used worldwide for over-the-road and off-highway hauling of commercial and consumer goods. The Company also designs and manufactures diesel engines, primarily for use in the Company’s trucks, at its facilities in Columbus, Mississippi; Eindhoven, the Netherlands; and Ponta Grossa, Brasil. PACCAR competes in the North American Class 8 market, primarily with Kenworth and Peterbilt conventional models. These trucks are assembled at facilities in Chillicothe, Ohio; Denton, Texas; Renton, Washington; Ste. Therese, CanadaWashington and Mexicali, Mexico. PACCAR also competes in the North American Class 6 to 7 markets primarily with Kenworth and Peterbilt conventional models. These trucks are assembled at facilities in Ste. Therese, CanadaCanada; Denton, Texas, and Mexicali, Mexico. PACCAR competes in the European light/medium market with DAF COE trucks assembled in the United Kingdom (U.K.) by Leyland, one of PACCAR’s wholly owned subsidiaries, and participates in the European heavy market with DAF COE trucks assembled in the Netherlands and the U.K. PACCAR competes in the Brazilian heavy truck market with DAF models assembled at Ponta Grossa in the state of Paraná, Brasil. PACCAR competes in the Australian medium and heavy truck markets with Kenworth conventional and COE models and certain DAF COE models assembled at its facility at Bayswater in the state of Victoria, Australia, and DAF COE models primarily assembled in the U.K. Commercial truck manufacturing comprises the largest segment of PACCAR’s business and accounted for 77%71% of total 20182021 net sales and revenues.

Substantially all trucks 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 worldwide by a foreign subsidiary headquartered in the Netherlands and is also marketed and distributed by foreign subsidiaries in Brasil and Australia. The decision to operate as a subsidiary or as a division is incidental to PACCAR’s 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, technical research and testing, treasury and finance functions. Some manufacturing plants in North America produce trucks for more than one nameplate, while other plants produce trucks for only one nameplate, depending on various factors. Best manufacturing practices within the Company are shared on a routine basis reflecting the similarity of the business models employed by each nameplate.

The Company’s trucks have a reputation for high quality products, most of which are ordered by dealers according to customer specifications. Some units are ordered by dealers for stocking to meet the needs of certain customers who require immediate delivery or for customers that require chassis to be fitted with specialized bodies. 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 PACCAR engines and axles and a higher percentage of other components for its heavy truck models. The Company also manufactures engines at its Columbus, Mississippi facility. In 2018,2021, the Company installed PACCAR engines in 41%approximately 38% of the Company’s Kenworth and Peterbilt heavy‑duty trucks in the U.S. and Canada and substantially all of the DAF heavy-duty trucks sold throughout the world. Engines not manufactured by the Company are purchased from Cummins Inc. (Cummins). The Company purchased a significant portion of its transmissions from Eaton Corporation Plc. (Eaton) and ZF Friedrichshafen AG (ZF). The Company also purchased a significant portion of North America stampings used for cabs from Magna International Inc. (Magna). The Company has long-term agreements with Cummins, Eaton, ZF and Magna to provide for continuity of supply. A loss of supply from Cummins, Eaton, ZF or Magna, and the resulting interruption in the production of trucks, would have a material effect on the Company’s results. Purchased materials and parts include raw materials, partially processed materials, such as castings, and finished components manufactured by independent suppliers. Raw materials, partially processed materials and finished components typically make up approximately 90%85% of the cost of new trucks. The value of major finished truck components manufactured by independent suppliers ranges from approximately 30%36% in Europe to approximately 87%86% in North America. In addition to materials, the Company’s cost of sales includes labor and factory overhead, vehicle delivery and warranty. Accordingly, except for certain factory overhead costs such as facilities depreciation, property taxes and utilities, the Company’s cost of sales are highly correlated to sales.

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 3% of consolidated revenues in 2018.2021. 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 require the Company to either 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. Manufacturing inventory levels are based upon production schedules, and orders are placed with suppliers accordingly.

Key factors affecting Truck segment earnings include the number of new trucks sold in the markets served and the margins realized on the sales. The Company’s sales of new trucks are dependent on the size of the truck markets served and the Company’s share of those markets. Truck segment sales and margins tend to be cyclical based on the level of overall economic activity, the availability of capital and the amount of freight being transported. The Company’s costs for trucks consist primarily of material costs, which are influenced by the price of commodities such as steel, copper, aluminum and petroleum. The Company utilizes long-term supply agreements to reduce the variability of the unit cost of purchased materials and finished components.components and engages in hedging activities for some commodities in certain geographical markets. The Company’s spending on research and development varies based on product development cycles and government requirements such as changes to diesel engine emissions and vehicle fuel efficiency standards in the various markets served. The Company maintains rigorous control of selling, general and administrative (SG&A) expenses and seeks to minimize such costs.

There are four principal competitors in the U.S. and Canada commercial truck market. The Company’s share of the U.S. and Canadian Class 8 market was 29.4%29.2% of retail sales in 2018,2021, and the Company’s medium-duty market share was 17.7%19.8%. In Europe, there are six principal competitors in the commercial truck market, including parent companies to twofour competitors of the Company in the U.S. In 2018,2021, DAF had a 16.6%15.9% share of the European heavy-duty market and a 9.0%10.1% share of the light/mediummedium-duty market. These markets are highly competitive in price, quality and service. 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.

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

The Company had a total production backlog of $14.7$15.9 billion at the end of 2018.2021. Within this backlog, orders scheduled for delivery within three months (90 days) are considered to be firm. The 90‑day backlog approximated $4.5$5.2 billion at December 31, 2018, $4.02021, $4.6 billion at December 31, 20172020 and $2.1$3.3 billion at December 31, 2016.2019. Production of the year-end 20182021 backlog is expected to be substantially completed during 2019.2022.

PARTS

The Parts segment includes the distribution of aftermarket parts for trucks and related commercial vehicles to over 2,200 Kenworth, Peterbilt and DAF dealers in 10395 countries around the world. Aftermarket truck parts are sold and delivered to the Company’s independent dealers through the Company’s 18 strategically located parts distribution centers (PDCs) in the U.S., Canada, Europe, Australia, Mexico and Central and South America. Parts are primarily purchased from various suppliers and also manufactured by the Company. Aftermarket parts inventory levels are determined largely by anticipated customer demand and the need for timely delivery. The Parts segment accounted for 16%21% of total 20182021 net sales and revenues.

Key factors affecting Parts segment earnings include the aftermarket parts sold in the markets served and the margins realized on the sales. Aftermarket parts sales are influenced by the total number of the Company’s trucks in service and the average age and mileage of those trucks. To reflect the benefit the Parts segment receives from costs incurred by the Truck segment, certain factory overhead, research and development, engineering and SG&A expenses are allocated from the Truck segment to the Parts segment. The Company’s cost for parts sold consists primarily of material costs, which are influenced by the price of commodities such as steel, copper, aluminum and petroleum. The Company utilizes long-term supply agreements to reduce the variability of the cost of parts sold. The Company maintains rigorous control of SG&A expenses and seeks to minimize such costs.

FINANCIAL SERVICES

PACCAR Financial Services (PFS) operates in 2426 countries in North America, Europe, Australia and South America through wholly owned finance companies operating under the PACCAR Financial trade name. PFS also conducts full servicefull-service leasing operations through operating divisions or wholly owned subsidiaries in North America, Germany and Australia under the PacLease trade name. Selected dealers in North America are franchised to provide full servicefull-service leasing. PFS provides its franchisees with equipment financing and administrative support. PFS also operates its own full service lease outlets. PFS’s retail loan and lease customers consist of small, medium and large commercial trucking companies, independent owner/operators and other businesses and acquire their PACCAR trucks principally from independent PACCAR dealers. PFS accounted for 6%7% of total net sales and revenues and 57%53% of total assets in 2018.2021.

PFS is primarily responsible for managing the sales of the Company’s used trucks. The Company’s Financial Services segment sells used trucks returned from matured operating leases in the ordinary course of business and trucks acquired from repossessions. PFS also obtains used trucks from the Truck segment in trades related to new truck sales and trucks returned from residual value guarantees (RVGs). Certain gains and losses from the sale of used trucks are shared with the Truck segment. The Company’s Financial Services segment records revenue on the sale of used trucks received in trade and RVG returns.

The Company’s finance receivables are classified as dealer wholesale, dealer retail and customer retail segments. The dealer wholesale segment consists of truck inventory financing to independent PACCAR dealers. The dealer retail segment consists of loans and leases to participating dealers and franchises, which use the proceeds to fund their customers’ acquisition of trucks and related equipment. The customer retail segment consists of loans and leases directly to customers for their acquisition of trucks and related equipment. Customer retail receivables are further segregated by fleet and owner/operator classes. The fleet class consists of customers operating more than five trucks. All others are considered owner/operators. Similar methods are employed to assess and monitor credit risk for each class.

Finance receivables are secured by the trucks and related equipment being financed or leased. The terms of loan and lease contracts generally range from three to five years depending on the type and use of equipment. Payment is required on dealer inventory financing when the floored truck is sold to a customer or upon maturity of the flooring loan, whichever comes first. Dealer inventory loans generally mature within one year.

The Company funds its financial services activities primarily from collections on existing finance receivables and borrowings in the capital markets. The primary sources of borrowings in the capital markets are commercial paper and medium-term notes issued in public and private offerings and, to a lesser extent, bank loans. An additional source of funds is loans from other PACCAR companies. PFS matches the maturity and interest rate characteristics of its debt with the maturity and interest rate characteristics of loans and leases.

Key factors affecting the earnings of the Financial Services segment include the volume of new loans and leases, the yield earned on the loans and leases, the costs of funding investments in loans and leases, and the ability to collect the amounts owed to PFS.PFS, the volume of used truck sales and used truck prices. New loan and lease volume is dependent on the volume of new trucks sold by Kenworth, Peterbilt and DAF and the share of those truck sales that are financed by the Financial Services segment. The Company’s Financial Services market share is influenced by the extent of competition in the financing market. PFS’s primary competitors include commercial banks and independent finance and leasing companies.

The revenue earned on loans and leases depends on market interest and lease rates and the ability of PFS to differentiate itself from the competition by superior industry knowledge and customer service. Dealer inventory loans have variable rates with rates reset monthly based on an index pertaining to the applicable local market. Retail loan and lease contracts normally have fixed rates over the contract term. PFS obtains funds either through fixed rate borrowings or through variable rate borrowings, a portion of which have been effectively converted to fixed rate through the use of interest-rate contracts. This enables PFS to obtain a stable spread between the

cost of borrowing and the yield on fixed rate contracts over the contract term. Included in Financial Services cost of revenues is depreciation on equipment on operating leases. The amount of depreciation on operating leases principally depends on the acquisition cost of leased equipment, the term of the leases, which generally ranges from three to five years, and the residual value of the leases, which generally ranges from 30% to 70%. The margin earned is the difference between the revenues on loan and lease contracts and the direct costs of operation, including interest and depreciation.

PFS incurs credit losses when customers are unable to pay the full amounts due under loan and finance lease contracts. PFS takes a conservative approach to underwriting new retail business in order to minimize credit losses.

The ability of customers to pay their obligations to PFS depends on the state of the general economy, the extent of freight demand, freight rates and the cost of fuel, among other factors. PFS limits its exposure to any one customer, with no one customer or dealer balance representing over 5% of the aggregate portfolio assets. PFS generally requires a down payment and secures its interest in the underlying truck collateral and may require other collateral or guarantees. In the event of default, PFS will repossess the truck and sell it in the open market primarily through its dealer network as well as PFS used truck centers. PFS will also seek to recover any shortfall between the amounts owed and the amounts recovered from sale of the collateral. The amount of credit losses depends on the rate of default on loans and finance leases and, in the event of repossession, the ability to recover the amount owed from sale of the collateral which is affected by used truck prices. PFS’s experience over the last fiftysixty years financing truck sales has been that periods of economic weakness result in higher past dues and increased rates of repossession. Used truck prices also tend to fall during periods of economic weakness. As a result, credit losses tend to increase during periods of economic weakness. PFS provides an allowance for credit losses based on specifically identified customer risks and an analysis of estimated losses inherent in the portfolio, considering the amount of past due accounts, the trends of used truck prices and the current and forecasted economic environment in eachconditions of its geographic markets.

Financial Services SG&A expenses consist primarily of personnel costs associated with originating and servicing the loan and lease portfolios. These costs vary somewhat depending on overall levels of business activity, but given the ongoing nature of servicing activities, tend to be relatively stable.

OTHER BUSINESSES

Other businesses include the manufacturing of industrial winches in two U.S. plants and marketing 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 total net sales and revenues in 2018, 20172021, 2020, and 2016.2019.

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

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.

ENVIRONMENTAL AND SUSTAINABILITY LEADERSHIP

Reducing the environmental impact of the Company’s activities and products is an integral part of the Company’s process of continuous improvement. PACCAR’s commitment to the environment is demonstrated in the Company’s energy efficient operations and technologically advanced products. The Company’s environmental management system and policy are designed to focus on the reduction of the environmental impacts of the Company’s activities, products and services.

Operations- PACCAR is committed to environmental responsibility in the vehicle production process. PACCAR’s facilities are continuously looking for ways to reduce waste, reuse materials, conserve energy and reduce the environmental impact of our activities. PACCAR’s factories are ISO 14001 certified and more than 80% are zero waste-to-landfill.

PACCAR has disclosed greenhouse gas emissions through CDP (formerly Carbon Disclosure Project) since 2014. In 2021, PACCAR achieved an A score from CDP, placing in the top 1.5% of over 13,000 companies reporting and demonstrating a robust approach to reducing greenhouse gas emissions in Kenworth, Peterbilt and DAF vehicles and from our global operations. PACCAR has earned an “A” or “A-” rating for seven consecutive years.

PACCAR has established new emissions reduction targets in partnership with the Science Based Targets Initiative (SBTi). SBTi works with more than 1,000 companies worldwide to create a clearly defined path to reduce greenhouse gas emissions, with the goal to help limit global warming to below 2 degrees Celsius compared to pre-industrial levels.

Innovative Products- A key element of PACCAR’s environmental strategy is to offer our customers commercial vehicles that reduce environmental impacts. The company invests in technologies that reduce greenhouse gas emissions such as highly fuel efficient diesel engines, natural gas and biofuel engines, as well as next generation electric, hybrid, and hydrogen fuel cell powertrains. To develop these industry-leading products and technologies, PACCAR makes significant research and development and capital investments every year.

PACCAR’s Zero Emission Trucks- PACCAR’s research and development efforts include several demonstration and development projects for Kenworth, Peterbilt and DAF vehicles, including battery electric, hydrogen fuel cell, hydrogen combustion and hybrid technologies. PACCAR is currently producing battery electric Kenworth, Peterbilt and DAF trucks.

Low Carbon and Renewable Fuels- PACCAR’s MX-13 and MX-11 engines are certified to use B10/B20/B30 and XTL biofuels in Europe and B20 biofuel in the U.S. Biofuel capable unit sales represent 49% of PACCAR’s total global truck sales.

Advanced Vehicles-PACCAR is launching its SuperTruck 3 program to continue the development of its Class 8 Kenworth and Peterbilt battery electric and fuel cell vehicles, along with its vehicle charging stations. SuperTruck 3 is a U.S. Department of Energy (DOE) initiative to develop state-of-the-art zero emissions medium- and heavy-duty trucks. The SuperTruck initiative was launched in 2009 by the DOE to improve heavy-duty truck freight efficiency. Kenworth and Peterbilt successfully developed state-of-the-art vehicles in the prior SuperTruck and SuperTruck 2 programs. Many of the technologies developed in the earlier SuperTruck programs were deployed in production vehicles, benefiting the environment and PACCAR’s customers.

Remanufacturing- Remanufacturing is the industrial process of returning a previously used component to “like-new” condition. Remanufacturing helps the environment by reducing waste. PACCAR’s aftermarket parts division sells remanufactured engines and many other remanufactured components.

Connected Trucks and Driver Training- The DAF Connect fleet management system gives fleet customers real-time information on vehicle and driver performance including fuel consumption, fleet utilization, idle time and route optimization. This information enables customers to improve fleet operating efficiency and reduce fuel consumption and CO2 emissions. PACCAR has introduced technologies that train drivers to operate vehicles more efficiently.

INFORMATION ABOUT THE COMPANY’S EXECUTIVE OFFICERS

Item 401(b) of Regulation S-K:

Information about the Company’s Executive Officers as of February 23, 2022 is as follows:

Officers are appointed by the Board of Directors annually but may be appointed or removed on interim dates.

The following are significant risks which could have a material negative impact on the Company’s financial condition or results of operations.

Business and Industry Risks

Commercial Truck Market Demand is Variable. The Company’s business is highly sensitive to global and national economic conditions as well as economic conditions in the industries and markets it serves. Negative economic conditions and outlook can materially weaken demand for the Company’s equipment and services. 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 Europe. Demand for commercial vehicles may also be affected by the introduction of new vehicles and technologies by the Company or its competitors.

Competition and Prices. The Company operates in a highly competitive environment, which could adversely affect the Company’s sales and pricing.Financial results depend largely on the ability to develop, manufacture and market competitive products that profitably meet customer demand.

Production Costs, Capacity and Supplier Capacity.Inflation. The Company’s products are exposed to variability in material and commodity costs. Commodity or component price increases, and significantcost pressures due to inflation, significant shortages of component products and labor availability may adversely impact the Company’s financial results or use of its production capacity. Many of the Company’s suppliers also supply automotive manufacturers, and factors that adversely affect the automotive industry can also have adverse effects on these suppliers and the Company. Supplier delivery performance can be adversely affected if increased demand for these suppliers’ products exceeds their production capacity. Unexpected events, including natural disasters, extreme weather events, or global pandemics, may increase the Company’s cost of doing business or disrupt the Company’s or its suppliers’ operations.

The automotive industry is currently experiencing a semiconductor supply shortage that is having wide-ranging effects across the automotive supply chain including some of the Company’s suppliers. During 2021, the shortage has had an impact on the ability of the Company to deliver products to dealers and customers. If the semiconductor supply shortage continues, the Company anticipates that production will be impacted in 2022.

Liquidity Risks, Credit Ratings and Costs of Funds. Disruptions or volatility in global financial markets could limit the Company’s sources of liquidity, or the liquidity of customers, dealers and suppliers. A lowering of the Company’s credit ratings could increase the cost of borrowing and adversely affect access to capital markets. The Company’s Financial Services segment obtains funds for its operations from commercial paper, medium-term notes and bank debt. If the markets for commercial paper, medium-term notes and bank debt do not provide the necessary liquidity in the future, the Financial Services segment may experience increased costs or may have to limit its financing of retail and wholesale assets. This could result in a reduction of the number of vehicles the Company is able to produce and sell to customers.

The Financial Services Industry is Highly Competitive. The Company’s Financial Services segment 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 truck unit sales and a decrease in truck residual values due to lower used truck pricingprices are also factors which may affect the Company’s Financial Services segment.

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.

Interest-Rate Risks. The Financial Services segment is subject to interest-rate risks, because increases in interest rates can reduce demand for its products, increase borrowing costs and potentially reduce interest margins.PFS uses derivative contracts to match the interest rateinterest-rate characteristics of itsits debt to the interest rate characteristics of its finance receivables in order to mitigate the risk of changing interest rates.

Information Technology. The Company relies on information technology systems and networks to process, transmit and store electronic information, and to manage or support a variety of its business processes and activities. These computer systems and networks may be subject to disruptions during the process of upgrading or replacing software, databases or components; power outages; hardware failures; computer viruses; or outside parties attempting to disrupt the Company’s business or gain unauthorized access to the Company’s electronic data. The Company maintains and continues to invest in protections to guard against such events. Examples of these protections include conducting third-party penetration tests, implementing software detection and prevention tools, event monitoring, and disaster recoverability. Additionally, the Company maintains a cybersecurity insurance policy. Despite these safeguards, there remains a risk of system disruptions, unauthorized access and data loss.

The Company may be adversely affected by political instabilities, fuel shortages or interruptions in utility or transportation systems, natural calamities, wars, terrorism and labor strikes.Changes in government monetary or fiscal policies and internationalinternational trade policies may impact demand for the Company’s products, financial results and competitive position.PACCAR’s global operations are subject to extensive trade, competition and anti-corruption laws and regulations that could impose significant compliance costs.

U.K. Exit

COVID-19 Pandemic. The COVID-19 pandemic and various governmental responses to contain the outbreak continue to impact global economic activity and the Company’s business. The economic disruptions from the European Unionpandemic are having an adverse effect on the Company’s revenues and operating results. The Company’s workforce at a given location could be affected by a localized outbreak of COVID-19, necessitating facility slowdowns or shutdowns. As a result of pandemic-related economic disruptions, if one or more of the Company’s suppliers could not produce needed parts or deliver at sufficient volumes to support the Company’s production plans or aftermarket requirements, revenues and operating results could be adversely affected.

The full extent and duration of the adverse effect on the Company’s business is uncertain and depends on the duration of the pandemic and the extent global and local economies are impacted by the effects of the pandemic. Changes to consumer behavior and labor markets as a result of COVID-19, as well as other pandemic related economic factors such as business failures, lower housing and construction starts, lower automobile sales, disruptions in financial markets or disruptions to the global supply chain, in particular the undersupply of semiconductor chips, could have further adverse effects on the Company’s truck and parts revenues and operating results and may result in lower new truck financing volume, higher finance portfolio past dues, credit losses and used truck losses. Other unforeseen impacts of the COVID-19 pandemic could also impact the Company’s business and results of operations.

London Inter-Bank Offered Rate (LIBOR) Transition. Certain financing provided by PFS to dealers and retail customers, as well as financing extended to PFS are based on variable interest rate contracts. These contracts utilize various benchmark rates, including LIBOR, to establish applicable contract interest rates. PACCAR also utilizes hedging instruments and has line of credit arrangements which reference LIBOR (including other similar benchmark rates). InOn March 2017, the United Kingdom (U.K.) invoked Article 50 of their treaty with the European Union signaling their intent to leave the EU. Under the EU Treaty5, 2021, the U.K. had two yearsFinancial Conduct Authority formally announced dates that various LIBOR rates will either stop being published or will be deemed as not representative. Certain tenors of U.S. LIBOR will be published through June 30, 2023, at which point they will have deemed to negotiate terms of their exit with the EU. Although a preliminary agreement between the EU and the U.K. Government was made, it was not ratified by the U.K. Parliament. If the termshave lost representativeness.

Substantially all of the exit fromCompany’s contracts which reference LIBOR, including dealer wholesale financing contracts, retail loan and lease contracts, medium-term notes, hedging instruments and line of credit arrangements, include fall-back language that specifies the EUmethods to establish contract interest rates in the absence of LIBOR, or provide for the use of an alternative benchmark rate should LIBOR be discontinued. Alternative benchmark rates are not agreed by March 29, 2019, it is anticipated that the standard trade protocols of the World Trade Organization (WTO) would become effective (“Hard Brexit”).now being used for all new retail loan and lease contracts.

The Company manufactures medium-has retail loan and heavy-duty DAF trucks inlease contracts with a December 31, 2021 balance of approximately $47 million, or less than 1% of PFS assets, referencing LIBOR that extend beyond June 30, 2023 and do not contain fall-back language or provide for the U.K. which are sold primarily inuse of an alternative benchmark rate. The Company will seek to amend these contracts to allow for the U.K. anduse of an alternative benchmark rate.

Changes to a lesser extent in Europebenchmark rates will have an uncertain impact on finance receivables and other world markets. In 2018, approximately 10% offinancial obligations, the Company’s worldwide truck production was manufactured in the U.K. Most of the truck components used in the manufacturing of trucks in the U.K., as well as aftermarket parts are sourced from the EU. In the event of a Hard Brexit, it is anticipated that there would be an increase in tariffs from truck components and parts from the EU which would increase thecurrent or future cost of all trucks and parts in the U.K. It is expected that there would also be an increase in tariffs on trucks sold from the U.K.funds and/or access to the EU which would lead to higher costs for trucks imported from the U.K into the EU.capital markets. The imposition of tariffs and border controls would most likely lead to longer lead times in the supply chain from the EU and the U.K. In the event of a Hard Brexit, the Company anticipates that after a period of time, changes would be made to the supply chainwill attempt to minimize the effectsimpact of tariffsdifferences between the current and delays. The higher costreplacement benchmark rates through pricing adjustments on the financing provided by PFS, but it is not certain the Company will be able to do so. Based on the current balance of trucksfinance contracts referencing LIBOR, it is estimated that for a 10 basis point difference between the current and parts may impact manufacturing and parts sales and margins which couldreplacement benchmark rates that the Company is unable to recover through pricing adjustments, income before income taxes would decrease by approximately $.7 million. Accordingly, the Company does not expect the anticipated changes to the use of LIBOR as a benchmark rate will have an adversea material impact on the Company’s results of operations.
