PART I
ITEM 1.BUSINESS
General
We are a transportation and logistics company engaged primarily in transporting truckload shipments of general commodities in both interstate and intrastate commerce. We also provide logistics services through our Werner Logistics segment. We believe we are one of the largest truckload carriers in the United States (based on total operating revenues), and our headquarters are located in Omaha, Nebraska, near the geographic center of our truckload service area. We were founded in 1956 by Clarence L. Werner, who started the business with one truck at the age of 19 and serves19. He served as our Executive Chairman.Chairman until his term ended at the 2021 Annual Meeting of Stockholders, and was then named Chairman Emeritus by the Board of Directors in recognition of his longstanding leadership. We were incorporated in the State of Nebraska in September 1982 and completed our initial public offering in June 1986 with a fleet of 632 trucks as of February 1986. At the end of 2017,2021, our Truckload Transportation Services (“Truckload”TTS”) segment had a fleet of 7,4358,340 trucks, of which 6,8058,050 were company-operated and 630290 were owned and operated by independent contractors. Our Werner Logistics division operated an additional 4555 intermodal drayage trucks at the end of 2017.2021.
We have two reportable segments – Truckloadacquired ECM Associated, LLC (“ECM”) in July 2021 and NEHDS Logistics, LLC (“NEHDS”) in November 2021. ECM, through its ECM Transport, LLC (“ECM Transport”) and Motor Carrier Service (“MCS”) subsidiaries, provides regional truckload carrier services in the Mid-Atlantic, Ohio, and Northeast regions of the U.S. and operates nearly 500 trucks and 2,000 trailers in its network of eight operational facilities and 18 drop yards. ECM achieved revenues of $108 million in 2020. NEHDS is a final mile residential delivery provider with access to a network of 400 final mile delivery trucks serving customers primarily in the Northeast and Midwest U.S. markets. NEHDS delivers primarily big and bulky products (primarily furniture and appliances) using 2-person delivery teams performing residential and commercial deliveries through a network of 19 cross dock, warehouse and customer facilities. We are rebranding NEHDS with our existing final mile business as Werner Logistics. You can find financialFinal Mile. NEHDS achieved revenues of $71 million for the 12-month period ended September 2021. These acquisitions expanded our fleet size, geographic market presence, and network of operational facilities. Additional information regarding these segments and the geographic areasacquisitions is included in which we conduct businessNote 2 in the Notes to Consolidated Financial Statements under Item 8 of Part II of this Form 10-K.
We have two reportable segments – TTS and Werner Logistics. Our TruckloadTTS segment is comprised of theDedicated and One-Way Truckload. Dedicated had 5,235 trucks as of December 31, 2021 and provides truckload services dedicated to a specific customer, generally for a retail distribution center or manufacturing facility, utilizing either dry van or specialized trailers. One-Way Truckload Dedicatedhad 3,105 trucks as of December 31, 2021 and Temperature Controlled. One-Way Truckload includes the following operating fleets: (i) the medium-to-long-haul van (“Van”) fleet transports a variety of consumer nondurable products and other commodities in truckload quantities over irregular routes using dry van trailers;trailers, including Mexico cross-border routes; (ii) the expedited (“Expedited”) fleet provides time-sensitive truckload services utilizing driver teams; and (iii) the regional short-haul (“Regional”) fleet, including ECM, provides comparable truckload van service within geographic regions across the United States. Dedicated provides truckload services dedicated to a specific customer, generally for a retail distribution center or manufacturing facility, utilizing either dry van or specialized trailers.States; and (iv) the Temperature Controlled fleet provides truckload services for temperature sensitive products over irregular routes utilizing temperature-controlled trailers. (We previously utilized the name “Specialized Services” to encompass the operations of both Dedicated and Temperature Controlled.) Our TruckloadTTS fleets operate throughout the 48 contiguous U.S. states pursuant to operating authority, both common and contract, granted by the U.S. Department of Transportation (“DOT”) and pursuant to intrastate authority granted by various U.S. states. We also have authority to operate in several provinces of Canada and to provide through-trailer service into and out of Mexico. The principal types of freight we transport include retail store merchandise, consumer products, groceryfood and beverage products and manufactured products. We focus on transporting consumer nondurable products that generally ship more consistently throughout the year and whose volumes are generally more stable during a slowdown in the economy.
Our Werner Logistics segment is a non-asset-based transportation and logistics provider.provider and generates the majority of our non-trucking revenues through three operating units. These three Werner Logistics is comprised of the following five operating units that provide non-trucking services to our customers:are as follows: (i) truck brokerage (“Brokerage”)Truckload Logistics, which uses contracted carriers to complete customer shipments; (ii)shipments for brokerage customers and freight management (“Freight Management”) offerscustomers for which we offer a full range of single-source logistics management services and solutions; (iii)(ii) the intermodal (“Intermodal”) unit offers rail transportation through alliances with rail and drayage providers as an alternative to truck transportation; and (iv) Werner Global Logistics international (“WGL”) provides complete management of global shipments from origin to destination using a combination of air, ocean, truck and rail transportation modes; and (v)(iii) Werner Final Mile (“Final Mile”), including NEHDS, offers homeresidential and businesscommercial deliveries of large or heavy items using two associatesthird-party agents, independent contractors, and Company employees with two-person delivery teams operating a liftgate

straight truck. Our Brokerage unitIn first quarter 2021, we completed the previously-announced sale of the Werner Global Logistics (“WGL”) freight forwarding services for international ocean and air shipments to Scan Global Logistics Group. WGL generated revenues of $53 million in 2020. Prior to the sale of WGL, Werner Logistics provided international services throughout North America and Asia, with additional coverage throughout Australia, Europe, South America, and Africa. Werner Logistics continues to provide North American truck brokerage, freight management, intermodal, and final mile services. Werner Logistics had transportation services contracts with 17,64126,834 carriers as of December 31, 2017.2021.
Marketing and Operations
Our business philosophy is to provide superior on-time customer service at a significant value for our customers. To accomplish this, we operate premium modern tractors and trailers. This equipment has fewer mechanical and maintenance issues and helps attract and retain experienced drivers. We continually develop our business processes and technology to improve customer service and driver retention. We focus on customers who value the broad geographic coverage, diversified truck and logistics services, equipment capacity, technology, customized services and flexibility available from a large, financially-stable transportation and logistics provider.

We operate in the truckload and logistics sectors of the transportation industry. Our TruckloadTTS segment provides specialized services to customers based on (i) each customer’s trailer needs (such as van and temperature-controlled trailers), (ii) geographic area (regional and medium-to-long-haul van, including transport throughout Mexico and Canada), (iii) time-sensitive shipments (expedited) or (iv) conversion of their private fleet to us (dedicated). In 2017, trucking revenues (net of fuel surcharge) and trucking fuel surcharge2021, TTS segment revenues accounted for 76%75% of total operating revenues, Werner Logistics revenues accounted for 23% of total operating revenues, and non-trucking and other operating revenues (primarily Werner Logistics revenues) accounted for 24% of total operating revenues.the remaining 2% was recorded in non-reportable segments. Our Werner Logistics segment manages the transportation and logistics requirements for customers, providing customers with additional sources of truck capacity, alternative modes of transportation, a global delivery network and systems analysis to optimize transportation needs. Werner Logistics services include (i) truck brokerage, (ii) freight management, (iii) intermodal transport, (iv) international and (v)(iv) final mile. The Werner Logistics international services are provided through our domestic and global subsidiary companies and include (i) ocean, air and ground transportation services, (ii) door-to-door freight forwarding and (iii) customs brokerage. Most Werner Logistics international services are provided throughout North America and Asia with additional coverage throughout Australia, Europe, South America and Africa. Werner Logistics is a non-asset-based transportation and logistics provider that is highly dependent on qualified associates, information systems and the services of qualified third-party capacity providers. You can find the revenues generated by services that accounted for more than 10% of our consolidated revenues, consisting of TruckloadTTS and Werner Logistics, for the last three years in Note 3 and Note 14 in the Notes to Consolidated Financial Statements under Item 78 of Part II of this Form 10-K.
We have a diversified freight base but are dependent on a relatively small number of customers for a significant portion of our freight.revenues. During 2017,2021, our largest 5, 10, 25 and 50 customers comprised 29%38%, 43%49%, 61%66% and 75%79% of our revenues, respectively. No singleOur largest customer, generated more than 8%Dollar General, accounted for 14% of our total revenues in 2017.2021. Revenues generated by Dollar General are reported in both of our reportable operating segments. The industry groups of our top 50 customers are 49%59% retail and consumer products, 27% grocery products, 13%18% manufacturing/industrial, 15% food and 11%beverage and 8% logistics and other. Many of our One-Way Truckload customer contracts may be terminated upon 30 days’ notice, which is common in the truckload industry. Most of ourWe are moving toward longer-term Dedicated customer contracts, most of which are onetwo to threefive years in length (including some contracts with annual evergreen clauses) and generally may be terminated by either party typically upon 30 to 90 days’a notice period following the expiration of the contract’s first year, and we generally reviewyear. We typically renegotiate rates inwith our customers for these Dedicated contracts annually.on an annual basis.
All of our company and independent contractor tractors are equipped with communication devices. These devices enable us and our drivers to conduct two-way communication using standardized and freeform messages. This technology also allows us to plan and monitor shipment progress. We automatically monitor truck movement and obtain specific data on the location of all trucks in the fleet every 15five minutes. Using the real-time global positioning data obtained from the devices, we have advanced application systems to improve customer and driver service. Examples of such application systems include: (i) an electronic logging system which records and monitors drivers’ hours of service and integrates with our information systems to pre-plan driver shipment assignments based on real-time available driving hours; (ii) software that pre-plans shipments drivers can trade enroute to meet driver home-time needs without compromising on-time delivery schedules; and (iii) automated “possible late load” tracking that informs the operations department of trucks possibly operating behind schedule, allowing us to take preventive measures to avoid late deliveries. In 1998, we began a successful pilot program and subsequently became the first trucking company in the United States to receive an exemption from DOT to use a global positioning-based paperless log system as an alternative to the paper logbooks traditionally used by truck drivers to track their daily work activities. We have used electronic logging devices (“ELDs”) to monitor and enforce drivers’ hours of service since 1996. Since January 2021, we use an untethered, tablet-based telematics solution that provides an enhanced and more efficient driver experience.
Seasonality
In the trucking industry, revenues generally follow a seasonal pattern. Peak freight demand has historically occurred in the months of September, October and November. After the December holiday season and during the remaining winter months, our freight volumes are typically lower because some customers reduce shipment levels. Our operating expenses have historically been higher in the winter months due primarily to decreased fuel efficiency, increased cold weather-related maintenance costs

of revenue equipment and increased insurance and claims costs attributed to adverse winter weather conditions. We attempt to minimize the impact of seasonality through our marketing program by seeking additional freight from certain customers during traditionally slower shipping periods and focusing on transporting consumer nondurable products. Revenue can also be affected by adverse weather conditions, holidays and the number of business days that occur during a given period because revenue is directly related to the available working days of shippers.
Human Capital Resources
Employee Associates and Independent Contractors
Count:As of December 31, 2017,2021, we employed 9,0439,988 drivers; 602595 mechanics and maintenance associates for the trucking operation; 1,2851,459 office associates for the trucking operation; and 1,2241,483 associates for Werner Logistics, international, driving schools and other non-trucking operations. We also had 630 independent contractors who provide both a tractorMost of our associates are based in the U.S., with about 1% based in Mexico and a driver or drivers.Canada. None of our U.S., or Canadian or Chinese associates are represented by a collective bargaining unit, and we consider relations with our associates to be good.

Health & Safety: Werner maintains a safety culture that is based on the premise of eliminating workplace incidents, risks and hazards. In 2021, we achieved our lowest work injury rate in 16 years. The Werner Safety Department is responsible for all compliance and training issues as it relates to drivers under DOT regulation and Werner policy. Responsibilities of the department include developing and delivering all driver training on items such as safety issues, driver certification, driver testing, and hazmat.
Our strong safety culture is demonstrated by ongoing investments in advanced equipment technologies, which lead to improved safety for our professional drivers. Nearly all of our company-owned trucks have collision-mitigation safety systems, automated manual transmissions, and forward-facing cameras.
During the COVID-19 pandemic, the transportation industry has been designated by the U.S. government as an essential industry for keeping the U.S. supply chain moving. Our drivers and mechanics have been on the front lines to ensure the delivery of essential products, and we take this responsibility seriously. Our primary focus will always be protecting the health and personal safety of our associates, their families and communities, and our customers. Throughout our offices and terminal network, we are closely following the safety guidelines set forth by the Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO).
Diversity & Inclusion: At Werner, we support and encourage the diverse voices and perspectives of our associates, our customers and our suppliers. Diversity contributes to innovation and connects us to the many communities we serve. We embrace these values as we move toward an increasingly inclusive culture where every associate feels empowered to bring their whole self to Werner. In 2021, all management associates completed diversity training focusing on unconscious bias and inclusion and we formed the Inclusion, Diversity, Equity, Accountability & Learning (IDEAL) Council to lead the creation, direction, and growth of Associate Resource Groups (“ARGs”). We currently have nine associate-led ARGs whose aim is to foster a diverse and inclusive workplace and provide support and help in personal and career development and create a safe space where associates can speak honestly and forthrightly. In 2022, we intend to establish reasonable goals for the advancement and retention of, and to increase and elevate, women and diverse talent in the management pipeline.
In 2021, we were recognized among the Top Companies for Women to Work for in Transportation by the Women in Trucking Association for the fourth consecutive year. Werner was recognized for our support of gender diversity, flexible hours and work requirements, competitive compensation and benefits, and professional development opportunities and career advancement opportunities. At Werner, our female driver workforce is well over the national average, and approximately half of our driver associates are ethnically diverse. Additionally, approximately half of our non-driver associates are female or ethnically diverse. Werner was also honored to be the only trucking company recognized as a 2021 Military Friendly® Company by VIQTORY Media. It is the fifth consecutive year Werner has received this designation. We are widely recognized as a transportation leader in military hiring with veterans and veteran spouses.
Professional Driver Recruitment:We recognize that our professional driver workforce is one of our most valuable assets. Most of our professional drivers are compensated on a per-mile basis. For most company-employed drivers, the rate per mile generally increases with the drivers’ length of service. Professional drivers may earn additional compensation through incentive performance pay programs and for performing additional work associated with their job (such as loading and unloading freight and making extra stops and shorter mileage trips).
At times, there are driver shortages in the trucking industry. Availability of experienced drivers can be affected by (i) changes in the demographic composition of the workforce; (ii) alternative employment opportunities other than truck driving that become available in the economy; and (iii) individual drivers’ desire to be home more frequently. The driver market remained challenging in 2017, and the supply of recent driver training school graduates continues to tighten. We believe that a declining number of, and increased competition for, driver training school graduates, an historically low national unemployment rate, aging truck driver demographics and increased truck safety regulations are tightening driver supply.

At Werner, we continue to take actions to strengthen our driver recruiting and retention to make Werner a preferred choice for the best drivers. Our efforts include raising driver pay, maintaining a new truck and trailer fleet, purchasing best-in-class safety features for all new trucks, investing in our driver training school network and collaborating with customers to improve or eliminate unproductive freight. We believe ourare focused on providing strong mileage utilization financial strength, safety record, and truck fleet age are attractive to drivers when compared to many other carriers. Additionally, we believe oura large percentage of driving jobs in shorter-haul operations (such as Dedicated and Regional) that allow drivers to return home more often is attractiveoften. We continue to drivers.improve our terminal network to enhance the driver experience. Our untethered, tablet-based telematics solution implemented in 2020 provides Werner drivers with a more efficient experience through smart workflow, best-in-class navigation, improved safety features and reduced manual data entry. While the trucking industry suffers from high driver turnover rates, we are proud that our efforts in recent years have continued to have positive results on our driver retention.
Talent Development:We utilize recent driver training school graduates as a significant source of new drivers. These drivers have completed a training program at a driver training school and hold a commercial driver’s license (“CDL”) and are further trained. They continue to gain industry experience through our career track program by partnering with a Werner-certified trainer driversleader prior to that driver becoming a solo driver with their own truck. As mentioned above, the recruiting environment for recent driver training school graduates remainedbecame even more challenging in 2017.2021 as social distancing requirements, state licensing cut backs and temporary closures limited the number of placement drivers entering our career track program. The availability of these drivers has also been negatively impacted by the decreased availability of student loan financing for driver training schools. We own two driver training schools that operateAt the end of 2021, we operated a total of 1319 driver training locations to assist with the training and development of drivers for our company and the industry.
As economic conditions improve, competition for experienced driversindustry, and recentwe expect to open three new driver training school graduates may increase and could become more challenging in 2018. We cannot predict whether we will experience future shortages in the availability of experienced drivers or driver training school graduates. If such a shortage were to occur and additional driver pay rate increases became necessary to attract and retain experienced drivers or driver training school graduates, our results of operations would be negatively impacted to the extent that we could not obtain corresponding freight rate increases.locations during first quarter 2022.
Independent Contractors:We also recognize that independent contractors complement our company-employed drivers. As of December 31, 2021, we had 290 independent contractors. Independent contractors supply their own tractors and drivers and are responsible for their operating expenses. Independent contractors also provide us with another source of drivers to support our fleet. We intend to maintain our emphasis on independent contractor recruiting, in addition to company driver recruitment. We, along with others in the trucking industry, however, continue to experience independent contractor recruitment and retention difficulties that have persisted over the past several years. Challenging operating conditions, including inflationary cost increases that are the responsibility of independent contractors and a shortage of financing available to independent contractors for equipment purchases, continue to make it difficult to recruit and retain independent contractors. If a shortage of independent contractors occurs, additional increases in per-mile settlement rates (for independent contractors) and driver pay rates (for company drivers) may become necessary to attract and retain a sufficient number of drivers. These increases could negatively affect our results of operations to the extent that we could not obtain corresponding freight rate increases.
Revenue Equipment
As of December 31, 2017,2021, we operated 6,8058,050 company tractors and 630290 tractors owned by independent contractors in our TruckloadTTS segment. Our Werner Logistics segment operated an additional 4555 drayage company tractors and 90 company delivery trucks at the end of 2017.2021. The TTS segment company tractors were primarily manufactured by Freightliner (a Daimler company), Peterbilt and Kenworth (both divisions of PACCAR) and International (a Navistar company). The Werner Final Mile company delivery trucks are manufactured by Hino. We adhere to a comprehensive maintenance program for both company tractors and trailers. We inspect independent contractor tractors prior to acceptance for compliance with Werner and DOT operational and safety requirements. We periodically inspect these tractors, in a manner similar to company tractor inspections, to monitor continued compliance. We also regulate the vehicle speed of company trucks to improve safety and fuel efficiency.
The average age of our TTS segment company truck fleet was 1.92.2 years at December 31, 2017,2021, compared to 1.82.0 years at December 31, 2016. At December 31, 2017, the2020. The average age of our trailer fleet was 4.7 years. In 2015 and 2016, we invested nearly $1 billion of capital expenditures (before sales of equipment) primarily4.5 years at December 31, 2021, compared to reduce the average age of our truck and trailer fleet.4.0 years at December 31, 2020. All of our trucks are equipped with satellite tracking devices. Approximately 86%devices, and nearly all of our company-owned trucks have collision mitigation safety systems and 76% of our company-owned trucks have automaticautomated manual transmissions.
We operated 24,50027,225 company-owned trailers at December 31, 2017,2021, comprised of dry vans, flatbeds, temperature-controlled, and other specialized trailers. Most of our trailers were manufactured by Wabash National Corporation.Corporation and Great Dane. Nearly all of our dry van trailer fleet consisted of 53-foot composite (DuraPlate®) trailers, and we also provide other trailer lengths such as 48-foot and 57-foot trailers, to meet the specialized needs of certain customers. Nearly 90%All of our trailer fleet hastrailers have satellite tracking; this is expected to grow to 100% of our trailer fleet by the end of 2018.

Our wholly-owned subsidiary, Werner Fleet Sales, sells our used trucks and trailers. Werner Fleet Sales has been in business since 1992 and operates in 8 locations. WeAt times, we may also trade used trucks to original equipment manufacturers when purchasing new trucks.
Fuel
In 2017,2021, we purchased nearly all of our fuel from a predetermined network of fuel truck stops throughout the United States comprised mostly of which approximately 96% was purchased from three large fuel truck stop chains. We negotiate discounted pricing based on historical purchase volumes with these fuel truck stop chains.chains and other factors.
Shortages of fuel, increases in fuel prices and rationing of petroleum products can have a material adverse effect on our operations and profitability. Our customer fuel surcharge reimbursement programs generally enable us to recover from our customers a majority, but not all, of higher fuel prices compared to normalized average fuel prices. These fuel surcharges,
4

Table of Contents
which automatically adjust depending on the U.S. Department of Energy (“DOE”) weekly retail on-highway diesel fuel prices, enable us to recoup much of the higher cost of fuel when prices increase and provide customers with the benefit of lower fuel costs when fuel prices decline. We do not generally recoup higher fuel costs for empty and out-of-route miles (which are not billable to customers) and truck idle time. We cannot predict whether fuel prices will increase or decrease in the future or the extent to which fuel surcharges will be collected from customers. As of December 31, 2017,2021, we had no derivative financial instruments to reduce our exposure to fuel price fluctuations.
We maintain aboveground and underground fuel storage tanks at manysome of our terminals. Leakage or damage to these facilities could expose us to environmental clean-up costs. The tanks are routinely inspected to help prevent and detect such problems.
We are committed to supporting global efforts to reduce carbon emissions and to continually evaluate and identify new environmental initiatives to support global sustainability efforts. We currently maintain a late-model truck fleet to take advantage of latest technologies to reduce fuel consumption and emissions. Our future environmental goals include doubling intermodal usage by 2030, thereby further reducing emissions, and by 2035, reducing carbon emissions by 55% compared to a 2007 baseline, with 30% or more of all Company truck miles being executed by zero emission vehicles.
Regulations
WeAs a for-hire motor carrier, we are regulated by the U.S. DOT, and certain areas of our business are subject to variousapplicable federal, state, and international laws and regulations. DOT and an agency within DOT, the Federal Motor Carrier Safety Administration (“FMCSA”), generally governsgovern matters such as safety requirements and compliance, registration to engage in motor carrier operations, drivers’ hours of service (“HOS”), and certain mergers, consolidations, and acquisitions. Werner maintains a satisfactory DOT safety rating, which is the highest available rating.rating of the three safety ratings given by FMCSA. A conditional or unsatisfactory DOT safety rating could adversely impact ourWerner’s business, as a proportionsome of our customer contracts require a satisfactory rating. Equipment weight and dimensions areWerner must also subject tocomply with federal, state, and international regulations with which we are required to comply.govern equipment weight and dimensions.
The Federal Motor Carrier Safety Administration’s (“FMCSA”)FMCSA’s Compliance, Safety, Accountability (“CSA”) safety initiative monitors the safety performance of motor carriers. In December 2010, FMCSA made publicCSA uses the Safety Measurement System (“SMS”), which includes monthly updates of specific safety rating measurement to analyze data from roadside inspections, crash reports, and percentile ranking scores for over 500,000 trucking companies. Through SMS, the public could access carrier scores for CSA’s Behavior Analysis and Safety Improvement Categories (“BASICs”).investigation results. The Fixing America’s Surface Transportation (“FAST”) Act of 2015 directed FMCSA to remove from public view thecertain information regarding carrier alertscarrier’s compliance and percentile ranks (i.e., scores).safety performance. The FAST Act also instructed FMCSA also was instructed to study the accuracy of CSA and SMS data and issue a corrective action plan to address the deficiencies identified in the study. In January 2016, FMCSA moved forward with a proposal to change the method for assigning a motor carrier’s Safety Fitness Determination (“SFD”) by using data from CSA. FMCSA withdrew the SFD proposed rule on March 23, 2017 and the agency must receive the National Academies of Sciences (“NAS”) study before determining whether further rulemaking action of SFD is necessary. In June 2017, NAS issued the Congressionally required study recommending that FMCSA adopt a new statistical model to measure motor carrier safety, along with other recommendations. In July 2017, FMCSA announced a planned demonstration project to consider requests from motor carriers to remove non-preventable crashes from their CSA records. We continueplan. Werner continues to monitor anyFMCSA’s actions and CSA related developments.
Interstate motor carriers are subject to the FMCSA HOS regulations. FMCSA adopted a final rule in December 2011 that included provisions affecting restart periods, rest breaks, on-duty time, and penalties for violations. We began dispatching drivers under the revisedregulations, which govern our drivers’ operating hours. The HOS rulesof Drivers Final Rule which became effective July 1, 2013. These rules were more restrictiveSeptember 29, 2020, includes provisions for short haul, adverse driving conditions, a revision to the 30-minute rest break requirement, and we believe adversely affected driver productivity. The Consolidated Appropriations Act of 2016 was passed by Congress with a provisionsplit-sleeper berth which allows drivers to reduce the negative effects of the restricted hours and required an FMCSA study to demonstrate results with statistically significant improvementssplit their 10-hour off duty period in safety, driver health, and other things, before the agency could reinstate the restart rule restrictions that became effective in July 2013. Language included in the Fiscal Year 2017 Continuing Resolution allowed carriers to comply with the pre-July 2013 restart provision.different ways. In March 2017, FMCSA released the HOS Restart study report indicating the restrictions do not improve safety; as a result, the pre-July 2013 restart rule continues to be in effect indefinitely.
In June 2017,August 2020, FMCSA proposed a pilot program to determine (i) the feasibility of adding split sleeper berth time options to the HOS regulations and (ii) whether such a change would improve safety. Once the Office of Management and Budget issues a final notice authorizing the data collection, FMCSA will then begin the pilot program and recruitallowing commercial drivers to participate.

Werner is the industry leader for ELDs to record driver hours and pioneered the Werner Paperless Logging System in 1996 that was subsequently approved for our use by FMCSA in 1998. In an effort to increase highway safety and improve compliance, Werner supported FMCSA’s ELD mandate. Legislative, regulatory, and legal efforts to delay the ELD final rule were unsuccessful and had minimal impact to the mandated implementation date. The final ELD rule was issued in December 2015, and on December 18, 2017, the final ruleFinal Rule went into effect in December 2017, requiring all motor carriers to have certified ELDs that meet specific standards for documenting HOS. Both the Commercial Vehicle Safety Alliance and
The FMCSA announced that out-of-service enforcement of ELDs will not begin until April 1, 2018.
FMCSA published a final rule that establishes the Commercial Driver’s License Drug and Alcohol Clearinghouse (the “Clearinghouse”) Final Rule was published in December 2016 whichwith the effective date of January 6, 2020. The Clearinghouse requires motor carriers, designated service agents, medical review officers, and substance abuse professionals to submit records related to drug and alcohol tests, to a nationwide database. Carriers and service agents are required to reportincluding test refusals and positive drug test results, as well asto the nationwide database. Motor carriers are also required to query the database prior to hiring an applicant. Compliance withapplicant and on an annual basis.
Continuing in 2022, motor carriers are required to perform annual random drug tests for 50% of existing drivers. The rate was increased from 25% on January 1, 2020 in response to the national drug2018 FMCSA Drug and Alcohol Testing Survey, which reported an increase to 1.0% of the random testing positive rate for controlled substances. The minimum annual percentage rate for random alcohol clearinghouse final rule is required starting in January 2020, three years after its effective date.testing remains at 10%.
FMCSA issued its final rule for Entry-Level Driver Training (“ELDT”) in December 2016. The final ruleHowever, after delays announced by FMCSA, the new effective date was February 7, 2022. ELDT now requires thatanyone wanting to obtain a Commercial Driver’s License to successfully complete a specific program of theory and behind-the-wheel proficiency be determinedinstruction provided by a school or other entity on FMCSA’s new Training Provider Registry.

Werner continues to comply with California’s Low Emission Transportation Refrigerated Unit (“TRU”) In-Use Performance Standards and its Tractor-Trailer GHG Reduction Rule, which is structured over a period of years to ensure ongoing compliance. We continue undertaking strategies to structure our fleet plans to operate compliant equipment in California.
WGL, through its domestic and global subsidiary companies, holds a variety Approximately 4% of licenses required to carry out its international services. These licenses permit us to provide services as a Non-Vessel Operating Common Carrier (“NVOCC”), customs broker, freight forwarder, indirect air carrier, accredited cargo agent and others. These international services subject us to regulation byour truck miles in 2021 were in the Transportation Security Administration (“TSA”) and Customs and Borders Protection (“CBP”) agenciesstate of the U.S. Department of Homeland Security, the U.S. Federal Maritime Commission (“FMC”), the International Air Transport Association (“IATA”), as well as similar regulatory agencies in foreign jurisdictions.California.
Our operations are subject to variousapplicable federal, state, and local environmental laws and regulations, many of which are implemented by the EPA and similar state regulatory agencies. These laws and regulations govern the management of hazardous wastes, discharge of pollutants into the air and surface and underground waters and disposal of certain substances. We do not believe that compliance with these regulations has a material effect on our capital expenditures, earnings, and competitive position.
Various provisions of the North American Free Trade Agreement (“NAFTA”) may alter the competitive environment regarding shipments in and out of Mexico and Canada. Recent political activity suggests that changes to NAFTA may be forthcoming, but we believe we are prepared to respond to any changes that may occur to this agreement. If negotiations result in a new agreement, it will need Congressional approval. We conduct a substantial amount of business in international freight shipments to and from the United States, Mexico, and Canada (see Note 8 in the Notes to Consolidated Financial Statements under Item 8 of Part II of this Form 10-K). We believe we are one of the largest truckload carriers in terms of freight volume shipped to and from the United States, Mexico, and Canada.
In Canada on December 16, 2017, a notice was issued in the Canada Gazette proposing amendments to the Commercial Vehicle Drivers HOS Regulations mandating the use of ELDs. The proposal would be aligned with similar ELD requirements in the United

States without introducing any impediments to trade. The newly proposed ELD regulations in Canada are not expected to have negative effects to our business model as Werner has used ELDs to record HOS since our Canadian operations started in 2000.
Werner is dedicated to participating in the development of meaningful public policy by continuing to evaluate local, state, and federal legislative and regulatory actions that impact our operations.
Competition
The freight transportation industry is highly competitive and includes thousands of trucking and non-asset-based logistics companies. We have a small share of the markets we target. Our TruckloadTTS segment competes primarily with other truckload carriers. Logistics companies, digital brokers, intermodal companies, railroads, less-than-truckload carriers and private carriers provide competition for both our TruckloadTTS and Werner Logistics segments. Our Werner Logistics segment also competes for the services of third-party capacity providers.
Competition for the freight we transport or manage is based primarily on service, efficiency, available capacity and, to some degree, on freight rates alone. We believe that few other truckload carriers have greater financial resources, own more equipment or carry a larger volume of freight than us. We believe we are one of the largest carriers in the truckload transportation industry based on total operating revenues.

Risks Related to our Business and Industry
Our business is subject to overall economic conditions that could have a material adverse effect on our results of operations.
We are sensitive to changes in overall economic conditions that impact customer shipping volumes, industry freight demand and industry truck capacity. When shipping volumes decline or available truck capacity increases, freight pricing generally becomes more competitive as carriers compete for loads to maintain truck productivity. We may be negatively affected by future economic conditions including employment levels, business conditions, fuel and energy costs, public health crises, interest rates and tax rates. Economic conditions may also impact the financial condition of our customers, resulting in a greater risk of bad debt losses, and that of our suppliers, which may affect negotiated pricing or availability of needed goods and services.
Difficulty in recruiting and retaining experienced drivers, recent driver training school graduates and independent contractors could impactimpacts our results of operations and limit growth opportunities.operations.
At times, the trucking industry has experienced driver shortages. Driver availability may be affected by changing workforce demographics, alternative employment opportunities, national unemployment rates, freight market conditions, availability of financial aid for driver training schools and changing industry regulations. If such a shortage were to occur and additional driver pay rate increases were necessary to attract and retain drivers, our results of operations would be negatively impacted to the extent that we could not obtain corresponding freight rate increases. Additionally, a shortage of drivers could result in idled equipment, which couldwould affect our profitability.

profitability and would limit growth opportunities.
Independent contractor availability may also be affected by both inflationary cost increases that are the responsibility of independent contractors and the availability of equipment financing. On-going federal and state legislative challenges to the independent contractor model could also affect independent contractor availability. In recent years, the topic of the classification of individuals as employees or independent contractors has gained increased attention among federal and state regulators as well as the plaintiffs’ bar. Various legislative or regulatory proposals have been introduced at the federal and state levels that may affect the classification status of individuals as independent contractors or employees for either employment tax purposes (e.g., withholding, social security, Medicare and unemployment taxes) or other benefits available to employees (e.g., workers’ compensation benefits and minimum wage). Recently, certain states (most prominently, California) have seen significant increased activity by tax and other regulators and numerous class action lawsuits filed against transportation companies that engage independent contractors. Potential changes, if any, that could impact the legal classification of the independent contractor relationship between us and our independent contractors could have a material adverse effect on our ability to recruit and retain independent contractors. If a shortage of independent contractors occurs, additional increases in per-mile settlement rates (for independent contractors) and driver pay rates (for company drivers) may become necessary to attract and retain a sufficient number of drivers. These increases couldwould negatively affect our results of operations to the extent that we would be unable to obtain corresponding freight rate increases.
Moreover, class action litigation in this area against other transportation companies has resulted in significant damage awards and/or monetary settlements for workers who have been allegedly misclassified as independent contractors.
Increases in fuel prices and shortages of fuel can have a material adverse effect on the results of operations and profitability.
To lessen the effect of fluctuating fuel prices on our margins, we have fuel surcharge programs with our customers. These programs generally enable us to recover a majority, but not all, of the fuel price increases. The remaining portion is generally not recoverable because it results from empty and out-of-route miles (which are not billable to customers) and truck idle time. Fuel prices that change rapidly in short time periods also impact our recovery because the surcharge rate in most programs only changes once per week. Fuel shortages, increases in fuel prices and petroleum product rationing could have a material adverse impact on our operations and profitability. To the extent that we cannot recover the higher cost of fuel through customer fuel surcharges, our financial results would be negatively impacted. As of December 31, 2017,2021, we had no derivative financial instruments to reduce our exposure to fuel price fluctuations.
We operate in a highly competitive industry, which may limit growth opportunities and reduce profitability.
The freight transportation industry is highly competitive and includes thousands of trucking and non-asset-based logistics companies. We compete primarily with other truckload carriers in our TruckloadTTS segment. Logistics companies, digital brokers, intermodal companies, railroads, less-than-truckload carriers and private carriers also provide a lesser degree of competition in our TruckloadTTS segment, but such providers are more direct competitors in our Werner Logistics segment. Competition for the freight we transport or manage is based primarily on service, efficiency, available capacity and, to some degree, on freight rates alone. This competition could have an adverse effect on either the number of shipments we transport or the freight rates we receive, which could limit our growth opportunities and reduce our profitability.
We operate in a highly regulated industry. Changes in existing regulations or violations

Table of existing or future regulations could adversely affect our operations and profitability.Contents
We are regulated by the DOT in the United States and similar governmental transportation agencies in foreign countries in which we operate. We are also regulated by agencies in certain U.S. states. These regulatory agencies have the authority to govern transportation-related activities, such as safety, authorization to conduct motor carrier operations and other matters. The Regulations subsection in Item 1 of Part I of this Form 10-K describes several proposed and pending regulations that may have a significant effect on our operations including our productivity, driver recruitment and retention and capital expenditures. The subsidiaries of WGL hold a variety of licenses required to carry out its international services, and the loss of any of these licenses could adversely impact the operations of WGL.
The seasonal pattern generally experienced in the trucking industry may affect our periodic results during traditionally slower shipping periods and winter months.
In the trucking industry, revenues generally follow a seasonal pattern which may affect our results of operations. After the December holiday season and during the remaining winter months, our freight volumes are typically lower because some customers reduce shipment levels. Our operating expenses have historically been higher in the winter months because of cold temperatures and other adverse winter weather conditions which result in decreased fuel efficiency, increased cold weather-related maintenance costs of revenue equipment and increased insurance and claims costs. Revenue can also be affected by adverse weather conditions, holidays and the number of business days during a given period because revenue is directly related to the available working days of shippers.
We depend on key customers, the loss or financial failure of which may have a material adverse effect on our operations and profitability.
A significant portion of our revenue is generated from key customers. During 2017,2021, our largest 5, 10, 25 and 2550 customers accounted for 29%38%, 43%49%, 66%, and 61%79% of revenues, respectively. No singleOur largest customer, generated more than 8%Dollar General, accounted for 14% of the our total revenues in 2017.2021. We do not have long-term contractual relationships with many of our key One-Way Truckload customers. Our contractual relationships withMost of our Dedicated customerscustomer contracts are typically onetwo to threefive years in length and generally may be terminated by either party typically upon 30 to 90 days’a notice period following the expiration of the contract’s first year, and we generally reviewyear. We typically renegotiate rates inwith our customers for these Dedicated contracts annually. We cannot provide any assurance that key customer relationships will continue at the same levels. If a key customer substantially reduced or terminated our services, it could have a material adverse effect on our business and results of operations. We review our customers’ financial conditions for granting credit, monitor changes in customers’ financial conditions on an ongoing basis and review

individual past-due balances and collection concerns. However, a key customer’s financial failure may negatively affect our results of operations.
We depend on the services of third-party capacity providers, the availability of which could affect our profitability and limit growth in our Werner Logistics segment.
Our Werner Logistics segment is highly dependent on the services of third-party capacity providers, such as other truckload carriers, less-than-truckload carriers, railroads, ocean carriersfinal-mile delivery contractors, and airlines.railroads. Many of those providers face the same economic challenges as we do and therefore are actively and competitively soliciting business. These economic conditions may have an adverse effect on the availability and cost of third-party capacity. If we are unable to secure the services of these third-party capacity providers at reasonable rates, our results of operations could be adversely affected.
If we cannot effectively manage the challenges associated with doing business internationally, our revenues and profitability may suffer.
Our results are affected by the success of our operations in Mexico China and other foreign countries in which we operate (see Note 814 in the Notes to Consolidated Financial Statements under Item 8 of Part II of this Form 10-K). We are subject to risks of doing business internationally, including fluctuations in foreign currencies, changes in the economic strength of the countries in which we do business, difficulties in enforcing contractual obligations and intellectual property rights, burdens of complying with a wide variety of international and United States export and import laws, and social, political, and economic instability. Additional risks associated with our foreign operations, including restrictive trade policies and imposition of duties, taxes, or government royalties by foreign governments, are present but have been largely mitigated by the terms of NAFTA for Mexico and Canada. The United States, Canada and Mexico ratified the USMCA as an overhaul and update to NAFTA, and it became effective in July 2020. We believe we are one of the largest truckload carriers in terms of freight volume shipped to and from the United States, Mexico, and Canada. It is currently difficult for Werner to anticipate the full impact of this agreement on foreign trade and our Mexico operations. The agreement permitting cross border movements for both United States and Mexican based carriers into the United States and Mexico presents additional risks in the form of potential increased competition and the potential for increased congestion on the cross border lanes between countries. Recent political activity suggests that changes to NAFTA may be forthcoming. This and other measures that may impact the level of trade between the United States, Mexico and Canada could negatively impact our volume of cross border shipments and thus, our results of operations.
Our earnings could be reduced by increases in the number of insurance claims, cost per claim, costs of insurance premiums or availability of insurance coverage.
We are self-insured for a significant portion of liability resulting from bodily injury, property damage, cargo and associate workers’ compensation and health benefit claims. This is supplemented by premium-based insurance with licensed insurance companies above our self-insurance level for each type of coverage. To the extent we experience a significant increase in the number of claims, cost per claim or insurance premium costs for coverage in excess of our retention amounts, our operating results would be negatively affected. Healthcare legislation and inflationary cost increases could also have a negative effect on our results.
Decreased demand for our used revenue equipment could result in lower unit sales, resale values and gains on sales of assets.
We are sensitive to changes in used equipment prices and demand, especially with respect to tractors. We have been in the business of selling our company-owned trucks since 1992, when we formed our wholly-owned subsidiary Werner Fleet Sales. Reduced demand for used equipment could result in a lower volume of sales or lower sales prices, either of which could negatively affect our gains on sales of assets.
Our operations are subject to various environmental laws and regulations, the violation of which could result in substantial fines or penalties.
In addition to direct regulation by DOT, EPA and other federal, state, and local agencies, we are subject to various environmental laws and regulations dealing with the handling of hazardous materials, aboveground and underground fuel storage tanks, discharge and retention of storm-water, and emissions from our vehicles. We operate in industrial areas, where truck terminals and other industrial activities are located and where groundwater or other forms of environmental contamination have occurred. Our operations involve the risks of fuel spillage or seepage, environmental damage and hazardous waste disposal, among others. We also maintain bulk fuel storage at several of our facilities. If we are involved in a spill or other accident involving hazardous substances, or if we are found to be in violation of applicable laws or regulations, it could have a material adverse effect on our business and operating results. If we fail to comply with applicable environmental regulations, we could be subject to substantial fines or penalties and to civil and criminal liability. Tractors and trailers used in our daily operations have been affected by regulatory changes related to air emissions and fuel efficiency, and may be adversely affected in the future by new regulatory actions.


We rely on the services of key personnel, the loss of which could impact our future success.
We are highly dependent on the services of key personnel, including our executive officers. Although we believe we have an experienced and highly qualified management team, the loss of the services of these key personnel could have a significant adverse impact on us and our future profitability.
Difficulty in obtaining materials, equipment, goods, and services from our vendors and suppliers could adversely affect our business.
We are dependent on our vendors and suppliers. We believe we have good vendor relationships and that we are generally able to obtain favorable pricing and other terms from vendors and suppliers. If we fail to maintain satisfactory relationships with our vendors and suppliers, or if our vendors and suppliers are unable to provide the products and materials we need or experience

significant financial problems, we could experience difficulty in obtaining needed goods and services because of production interruptions, limited material availability, or other reasons. Consequently,Currently, tractor and trailer manufacturers are experiencing significant shortages of semiconductor chips and other component parts and supplies, forcing many manufacturers to reduce or suspend their production, which has led to a lower supply of tractors and trailers, higher prices, and lengthened trade cycles, which could have a material adverse effect on our business, could be adversely affected.financial condition, and results of operations, particularly our maintenance expense, mileage productivity, and driver retention.
We use our information systems extensively for day-to-day operations, and service interruptions or a failure of our information technology infrastructure or a breach of our information security systems, networks or processes could have a material adverse effect on our business.
We depend on the stability, availability and security of our information systems to manage our business. Much of our software was developed internally or by adapting purchased software applications to suit our needs. Our information systems are used for planning loads, communicating with and dispatching drivers and other capacity providers, billing customers, paying vendors and providing financial reports. We rely on strategic vendors for GPS and satellite communication services, which are integrated in our information systems. If any of our critical information systems fail or become unavailable, or those of our service providers, we would have to perform certain functions manually, which could temporarily affect our ability to efficiently manage our operations. We have redundant computer hardware systems to reduce this risk. We also maintain information security policies to protect our systems and data from cyber security events and threats. The security risks associated with information technology systems have increased in recent years because of the increased sophistication, activities and evolving techniques of perpetrators of cyber attacks. The techniques used to obtain unauthorized access, disable or degrade service or sabotage systems change frequently, may be difficult to detect for a long time and often are not recognized until launched against a target. As a result, we may be unable to anticipate these techniques or to implement adequate preventative measures. A failure in or breach of our information technology security systems, or those of our third-party service providers, as a result of cyber attacks or unauthorized network access could disrupt our business, result in the disclosure or misuse of confidential or proprietary information, increase our costs and/or cause losses and reputational damage. In addition, recently, there has also been heightened regulatory and enforcement focus on data protection in the U.S., and failure to comply with applicable U.S. data protection regulations or other data protection standards may expose us to litigation, fines, sanctions or other penalties, which could harm our reputation and adversely impact our business, results of operations and financial condition.
The COVID-19 pandemic has adversely impacted our business, as well as the operations of our customers and suppliers.
The COVID-19 pandemic has resulted in a slowdown of economic activity and a disruption in supply chains. Our business is sensitive to changes in overall economic conditions that impact customer shipping volumes, industry freight demand and industry truck capacity. Such conditions may also impact the financial condition of our customers, resulting in a greater risk of bad debt losses, and that of our suppliers, which may affect the availability or pricing of needed goods and services. Although we have taken numerous actions to lessen the adverse impact of the COVID-19 pandemic, our 2022 results could be further impacted by the disruptive effects of COVID-19, including but not limited to adverse effects on freight volumes and pricing and availability of qualified personnel. Such outbreaks could affect our operations and business continuity if a significant number of our essential employees, overall or in a key location, are quarantined from contraction of or exposure to the disease or if future governmental orders prevent our employees or critical suppliers (including individuals that have not received mandated vaccinations) from working. Our compliance with mandates could lead to employee absences, resignations, labor disputes, or work stoppages. The degree of disruption is difficult to predict because of many factors, including the uncertainty surrounding the magnitude and duration of the pandemic, governmental actions that have been and may continue to be imposed, as well as the rate of economic recovery after the pandemic subsides. The unpredictable nature and uncertainty of the current COVID-19 pandemic could also magnify other risk factors disclosed above and makes it impractical to identify all potential risks.
Risks Related to Laws and Regulations
We operate in a highly regulated industry. Changes in existing regulations or violations of existing or future regulations could adversely affect our operations and profitability.
We are regulated by the DOT and its agency the FMCSA in the United States and similar governmental transportation agencies in foreign countries in which we operate. We are also regulated by agencies in certain U.S. states. These regulatory agencies have the authority to govern transportation-related activities, such as safety, authorization to conduct motor carrier operations and other matters.

In addition to direct regulation by DOT, FMCSA, EPA and other federal, state, and local agencies, we are subject to applicable environmental laws and regulations dealing with the handling of hazardous materials, aboveground and underground fuel storage tanks, discharge and retention of storm-water, and emissions from our vehicles. We operate in industrial areas, where truck terminals and other industrial activities are located and where groundwater or other forms of environmental contamination have occurred.

Tractors and trailers used in our daily operations have been affected by regulatory changes related to air emissions and fuel efficiency, and may be adversely affected in the future by new regulatory actions.
Risks Related to Financial Matters
Our earnings could be reduced by increases in the number of insurance claims, cost per claim, costs of insurance premiums or availability of insurance coverage.
We are self-insured for a significant portion of liability resulting from bodily injury, property damage, cargo and associate workers’ compensation and health benefit claims. This is supplemented by premium-based insurance coverage with insurance carriers above our self-insurance level for each type of coverage. To the extent we experience a significant increase in the number of claims, cost per claim (including costs resulting from large verdicts) or insurance premium costs for coverage in excess of our retention and deductible amounts, our operating results would be negatively affected. Although we believe our aggregate insurance limits should be sufficient to cover reasonably expected claims, it is possible that the amount of one or more claims could exceed our aggregate coverage limits. In addition, the transportation industry has recently experienced significant increases in premiums for insurance coverage above self-insurance levels. Healthcare legislation and inflationary cost increases could also have a negative effect on our results.
Decreased demand for our used revenue equipment could result in lower unit sales and resale values.
We are sensitive to changes in used equipment prices and demand, especially with respect to tractors. We have been in the business of selling our company-owned trucks since 1992, when we formed our wholly-owned subsidiary Werner Fleet Sales. Reduced demand for used equipment could result in a lower volume of sales or lower sales prices, either of which could negatively affect our proceeds from sales of assets.

ITEM 3.LEGAL PROCEEDINGS
We are a party subject to routine litigation incidental to our business, primarily involving claims for bodily injury, property damage, cargo and workers’ compensation incurred in the transportation of freight. We have maintained a self-insuranceFor more information about our insurance program with a qualified departmentand legal proceedings, see Item 1A, Risk Factors – “Our earnings could be reduced by increases in the number of risk management professionals since 1988. These associates manage our bodily injury, property damage, cargo and workers’ compensation claims. An actuary reviews our undiscounted self-insurance reserves for bodily injury, property damage and workers’ compensationinsurance claims, at year-end.
We renewed our liability insurance policies on August 1, 2017 and took on additional risk exposure by increasing our self-insurance retention (“SIR”) and deductible levels. Effective August 1, 2017, our SIR and deductible amount is $3.0 million, plus administrative expenses, for each occurrence involving bodily injury or property damage, compared to $2.0 million for all policy years since August 1, 2004. We are also responsible for varying annual aggregate amounts of liability for claims in excess of the SIR/deductible. For the policy year that began August 1, 2017, we have an annual $6.0 million aggregate for claims between $3.0 million and $5.0 million. We also have an additional $5.0 million deductiblecost per claim, for each claim between $5.0 millioncosts of insurance premiums or availability of insurance coverage”, Item 7, Management’s Discussion and $10.0 million.

Business Acquisitions:
ECM Acquisition
On July 1, 2021, we acquired an 80% equity ownership interest in ECM for a cash purchase price of $141.3 million after net working capital changes and net of cash acquired. ECM achieved revenues of $108 million in 2020 with an operating margin of 19.8%. ECM consists of ECM Transport and MCS, which are regional truckload carriers that together operate nearly 500 trucks and 2,000 trailers in the Mid-Atlantic, Ohio and Northeast regions of the U.S. with low driver turnover. Revenues generated by ECM Transport and MCS are reported in One-Way Truckload within our TTS segment.
We financed the transaction through a combination of cash on hand, existing credit facilities and a new $100.0 million unsecured fixed-rate term loan maturing in May 2024 with BMO Harris Bank N.A., one of our two lead banks. The remaining 20% ownership interest in ECM is retained by Ed Meier, founder and President of ECM.
NEHDS Acquisition
On November 22, 2021, we acquired 100% of the equity interests in NEHDS for a cash purchase price of $63.1 million after including the impacts of contingent consideration, net working capital changes and cash acquired. We financed the transaction through a combination of cash on hand and existing credit facilities. NEHDS achieved revenues of $71 million for the 12-month period ended September 2021 and produced an average annual revenues growth rate of 27% over the last three years. NEHDS is a final mile residential delivery provider with access to a network of 400 final mile delivery trucks serving customers primarily in the Northeast and Midwest U.S. markets. Revenues generated by NEHDS are reported in Final Mile within our Werner Logistics segment.
Additional information regarding the ECM and NEHDS acquisitions is included in Note 2 in the Notes to Consolidated Financial Statements under Item 8 of Part II of this Form 10-K.
Overview:
We have two reportable segments, TruckloadTTS and Werner Logistics, and we operate in the truckload and logistics sectors of the transportation industry. In the truckload sector, we focus on transporting consumer nondurable products that generally ship more consistently throughout the year. In the logistics sector, besides managing transportation requirements for individual
15

Table of Contents
customers, we provide additional sources of truck capacity, alternative modes of transportation, a globalNorth American delivery network and systems analysis to optimize transportation needs. Our success depends on our ability to efficiently and effectively manage our resources in the delivery of truckload transportation and logistics services to our customers. Resource requirements vary with customer demand, which may be subject to seasonal or general economic conditions. Our ability to adapt to changes in customer transportation requirements is essential to efficiently deploy resources and make capital investments in tractors and trailers (with respect to our TruckloadTTS segment) or obtain qualified third-party capacity at a reasonable price (with respect to our Werner Logistics segment). Although our business volume is not highly concentrated, weWe may also be affected by our customers’ financial failures or loss of customer business.
Revenues for our TruckloadTTS segment operating units (One-Way Truckload, Dedicated(Dedicated and Temperature Controlled)One-Way Truckload) are typically generated on a per-mile basis and also include revenues such as stop charges, loading and unloading charges, equipment detention charges and equipment repositioning charges. To mitigate our risk to fuel price increases, we recover additional fuel surcharge revenues from our customers additional fuel surcharges that generally recoup a majority of the increased fuel costs; however, we cannot assure that current recovery levels will continue in future periods. Because fuel surcharge revenues fluctuate in response to changes in fuel costs, we identify them separately and exclude them from the statistical calculations to provide a more meaningful comparison between periods. The key statistics used to evaluate trucking revenues, net of fuel surcharge, are (i) average revenues per tractor per week, (ii) average percentage of empty miles (miles without trailer cargo), (iii) average trip length (in loaded miles) and (iv) average number of tractors in service. General economic conditions, seasonal trucking industry freight patterns and industry capacity are important factors that impact these statistics. Our TruckloadTTS segment also generates a small amount of revenues categorized as non-trucking revenues, which consist primarily of the intra-Mexico portion of cross-border shipments delivered to or from Mexico where the TruckloadTTS segment utilizes a third-party capacity provider. We exclude such revenues from the statistical calculations.
Our most significant resource requirements are company drivers, independent contractors, tractors and trailers. Independent contractors supply their own tractors and drivers and are responsible for their operating expenses. Our financial results are affected by company driver and independent contractor availability and the markets for new and used revenue equipment. We are self-insured for a significant portion of bodily injury, property damage and cargo claims; workers’ compensation claims; and associate health claims (supplemented by premium-based insurance coverage above certain dollar levels). For that reason, our financial results may also be affected by driver safety, medical costs, weather, legal and regulatory environments and insurance coverage costs to protect against catastrophic losses.
The operating ratio is a common industry measure used to evaluate our profitability and that of our TruckloadTTS segment operating fleets. The operating ratio consists of operating expenses expressed as a percentage of operating revenues. The most significant variable expenses that impact the TruckloadTTS segment are driver salaries and benefits, fuel, fuel taxes (included in taxes and licenses expense), payments to independent contractors (included in rent and purchased transportation expense), supplies and maintenance and insurance and claims. As discussed further in the comparison of operating results for 20172021 to 2016,2020, several industry-wide issues have caused, and could continue to cause, costs to increase in future periods. These issues include shortages of drivers or independent contractors, changing fuel prices, higher new truck and trailer purchase prices and compliance with new or proposed regulations.regulations and tightening of the commercial truck liability insurance market. Our main fixed costs include depreciation expense for tractors and trailers and equipment licensing fees (included in taxes and licenses expense). The TruckloadTTS segment requires substantial cash expenditures for tractor and trailer purchases. We fund these purchases with net cash from operations and financing available under our existing credit facilities, as management deems necessary.
We provide non-trucking services primarily through the fivethree operating units within our Werner Logistics segment (Brokerage, Freight Management,(Truckload Logistics, Intermodal, WGL and Final Mile). In first quarter 2021, we completed the previously-announced sale of the Werner Global Logistics (“WGL”) freight forwarding services for international ocean and air shipments to Scan Global Logistics Group. WGL had annual revenues of $53 million in 2020, and we realized a $1.0 million gain from the sale in first quarter 2021. Unlike our TruckloadTTS segment, the Werner Logistics segment is less asset-intensive and is instead dependent upon qualified associates, information systems and qualified third-party capacity providers. The largest expense item related to the Werner Logistics segment is the cost of purchased transportation we pay to third-party capacity providers. This expense item is recorded as rent and purchased transportation expense. Other operating expenses consist primarily of salaries, wages and benefits.benefits, as well as depreciation, supplies and maintenance, and other general expenses. We evaluate the Werner Logistics segment’s financial performance by reviewing the

gross margin percentage (revenues less rentoperating expenses and purchased transportation expensesoperating income expressed as a percentage of revenues) and the operating income percentage. The gross marginrevenues. Purchased transportation expenses as a percentage of revenues can be impacted by the rates charged to customers and the costs of securing third-party capacity. We have a mix of contracted long-term rates and variable rates for the cost of third-party capacity, and we cannot assure that our operating results will not be adversely impacted in the future if our ability to obtain qualified third-party capacity providers changes or the rates of such providers increase.
At the end of 2021, we believe we are well positioned with a strong balance sheet and sufficient liquidity. Our debt is at $428 million, or a net debt ratio of 0.6 times earnings before interest, income taxes, depreciation and amortization for the year ended December 31, 2021. We had available liquidity of $169 million, considering cash on hand and available credit facilities of $115 million. We also have sufficient cushion with our debt covenants. We currently plan to continue paying our quarterly dividend,
16

Table of Contents
which we have paid quarterly since 1987. This cash outlay currently results in slightly less than $8 million per quarter. Net capital expenditures (primarily revenue equipment) in 2022 currently are expected to be in the range of $275 million to $325 million.
COVID-19:
The COVID-19 pandemic continues to impact the U.S. and global economies and has resulted in ongoing supply chain challenges. During the pandemic, the transportation industry has been designated by the U.S. government as an essential industry for keeping the U.S. supply chain moving. We are monitoring and reacting to the evolving nature of the pandemic, governmental responses, and their impacts on our business, including employee availability. We are working hard to stay healthy while safely delivering our customers’ freight on time. Throughout our offices and terminal network, we are closely following the safety guidelines set forth by the Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO).
Over the past several years, we have repositioned Werner to increase our ability to execute through different macroeconomic environments. We believe our freight base, which is heavily weighted toward customers delivering essential products that are continually being restocked in today’s economy, enabled us to more effectively manage through the difficult economic environment created by the pandemic. While there remain significant uncertainties related to COVID-19 and its effect on the economy, we believe that demand for our services will be strong in 2022.

Operating Revenues
Operating revenues increased 5.4%15.3% in 20172021 compared to 2016.2020. When comparing 20172021 to 2016, Truckload2020, TTS segment revenues increased $101.3$201.9 million, or 6.6%, of which nearly half resulted from higher fuel surcharge revenues due to higher fuel prices.11.0%. Revenues for the Werner Logistics segment increased $0.5 million.$152.7 million or 32.5%.
Freight demand was strong throughout 2021 in our Dedicated and One-Way Truckload fleet was seasonally softer with weaker trends early in 2017, but began to improve to more normal seasonal levels in March.fleets. Freight demand has continued to improve through August, trending better than normal and better thanbe strong during the more challenging periods of 2016. Beginning in September, the freight market strengthened further due in part to thefirst two major hurricanes in Texas and Florida. While these events resulted in short-term costs to the Company, at the same time, they improved spot market pricing and further widened the positive gap between demand and capacity leading into peak season. Fourth quarter 2017 freight demand in our One-Way Truckload fleet was strong. Freight in October 2017 was seasonally better than normal, and demand strengthened further in November and December. Freight volumes thus far in 2018 have been much stronger than normal compared to the same months of previous years.2022.
Trucking revenues, net of fuel surcharge, increased 3.5%7.3% in 20172021 compared to 20162020 due to a 2.9%4.3% increase in average revenues per tractor per week, net of fuel surcharge revenues. Theand a 2.9% increase in the average number of tractors in service increased 0.6% from 2016service. The increase in average revenues per tractor was due primarily to 2017. Averageimproved pricing in both Dedicated and One-Way Truckload, partially offset by a decline in miles per truck remained flat from 2016tractor caused by tractors down due to 2017,equipment parts shortages, more drivers unavailable to work due to COVID quarantine protocols, a 2% shorter average loaded length of haul for the TTS segment, and other factors. We currently expect average revenues per total mile, net of fuel surcharge, revenues, increased 2.9%. Freight metrics are improving,for the One-Way Truckload fleet to remain strong for the first half of 2022 and to increase in a range of 16% to 19% when compared to the first half of 2021, and we have increasing confidence that contractual rates will strengthen over the

next few quarters. We currently expect an increase in theDedicated average revenues per total mile,tractor per week, net of fuel surcharge, revenues,to increase in 2018 in thea range of 6%3% to 10%.5% in 2022 compared to 2021.
The average number of tractors in service in the TruckloadTTS segment increased 2.9% to 7,3057,982 in 20172021 compared to 7,2637,757 in 2016.2020. We ended 20172021 with 7,4358,340 tractors in the TruckloadTTS segment, a year-over-year increase of 335 trucks.510 tractors, primarily resulting from the nearly 500 tractors acquired in the ECM acquisition. Our Dedicated unit ended 20172021 with 4,000 trucks5,235 tractors (or 54%63% of our total TruckloadTTS segment fleet) compared to 3,650 trucks4,945 tractors at the end of 2016.2020. We currently expect our fleet size at the end of 2022 to be in a range of 2% to 5% higher when compared to the fleet size at the end of 2021, subject to driver availability and timing of delivery of new tractors from our equipment manufacturers. We cannot predict whether future driver shortages, if any, will adversely affect our ability to maintain our fleet size. If such a driver market shortage were to occur, it could result in a fleet size reduction, and our results of operations could be adversely affected.
Trucking fuel surcharge revenues increased 32.3%47.6% to $205.5$234.2 million in 20172021 from $155.3$158.6 million in 2016 because of2020 due primarily to higher average diesel fuel prices, partially offset by fewer miles in 2017.2021. These revenues represent collections from customers for the increase in fuel and fuel-related expenses, including the fuel component of our independent contractor cost (recorded as rent and purchased transportation expense) and fuel taxes (recorded in taxes and licenses expense), when diesel fuel prices rise. Conversely, when fuel prices decrease, fuel surcharge revenues decrease. To lessen the effect of fluctuating fuel prices on our margins, we collect fuel surcharge revenues from our customers for the cost of diesel fuel and taxes in excess of specified base fuel price levels according to terms in our customer contracts. Fuel surcharge rates generally adjust weekly based on an independent U.S. Department of Energy fuel price survey which is released every Monday. Our fuel surcharge programs are designed to (i) recoup higher fuel costs from customers when fuel prices rise and (ii) provide customers with the benefit of lower fuel costs when fuel prices decline. These programs generally enable us to recover a majority, but not all, of the fuel price increases. The remaining portion is generally not recoverable because it results from empty and out-of-route miles (which are not billable to customers) and trucktractor idle time. Fuel prices that change rapidly in short time periods also impact our recovery because the surcharge rate in most programs only changes once per week.

Werner Logistics revenues are generated by its fivethree operating units, following the sale of its WGL freight forwarding services for international ocean and air shipments in first quarter 2021. Werner Logistics revenues exclude revenues for full truckload shipments transferred to the TruckloadTTS segment, which are recorded as trucking revenues by the TruckloadTTS segment. Werner Logistics also recorded revenue and brokered freight expense of $0.8$0.9 million in 20172021 and $1.0$0.1 million in 20162020 for Intermodal drayage movements performed by the TruckloadTTS segment (also recorded as trucking revenuesrevenue by the TruckloadTTS segment), primarily related to Intermodal drayage, and these transactions between reporting segments are eliminated in consolidation. Werner Logistics revenues increased 0.1%32.5% to $417.6$622.5 million in 20172021 from $417.2$469.8 million in 2016. The2020 due primarily to higher pricing and volume growth in Truckload Logistics and Intermodal, and an $8.8 million increase in Final Mile revenues primarily due to the impact of NEHDS acquired in November 2021. Truckload Logistics revenues (68% of total Logistics revenues) increased 58% due to 29% higher revenues per shipment and a 23% increase in volume. Intermodal revenues (26% of total Logistics revenues) increased 37% due to 35% higher revenues per shipment and a 1% increase in volume. Werner Logistics gross margin dollars decreased 13.0%operating income increased to $62.1$27.9 million in 2017 from $71.42021 compared to $6.0 million in 2016,2020, due to revenue growth and the Werner Logistics grossa 320 basis point expansion of operating margin percentage decreased to 14.9% in 2017 from 17.1% in 2016.a strong freight market. The Werner Logistics operating incomemargin percentage decreasedincreased to 2.1%4.5% in 20172021 from 5.0%1.3% in 2016. Tighter carrier capacity in 2017 compared2020. We expect Werner Logistics to 2016 resulted in higher purchased transportation costs for our predominantly contractual logistics business, causing the lower gross marginachieve continued revenue and operating income percentages.
In 2017, Werner Logistics achieved 26% revenue growth over 2016 in our truck brokerage solution, while our intermodal and international solutions had lower revenues due to more challenging market conditions. As previously disclosed, a large Werner Logistics Freight Management customer (5.0% of Werner Logistics revenues in 2016) that was acquired in 2015 transitioned to their parent company’s transportation platform mid-quarter during first quarter 2017. We continue to see strong customer acceptance of the value of the Werner Logistics portfolio of service offerings, particularly as the market strengthens and shippers tend to consolidate their logistics business with the stability of larger asset-backed logistics providers. Achieving contractual rate increases in 2018 to recoup rising costs of third-party capacity is a focus for Werner Logistics.2022.
Operating Expenses
Our operating ratio (operating expenses expressed as a percentage of operating revenues) was 93.2%88.7% in 20172021 compared to 93.7%90.4% in 2016.2020. Expense items that impacted the overall operating ratio are described on the following pages. The tables on pages 1517 through 1619 show the Consolidated Statementsconsolidated statements of Incomeincome in dollars and as a percentage of total operating revenues and the percentage increase or decrease in the dollar amounts of those items compared to the prior year, as well as the operating ratios, operating margins and certain statistical information for our two reportable segments, TruckloadTTS and Werner Logistics.
Salaries, wages and benefits increased $45.4$99.2 million or 7.1%12.5% in 20172021 compared to 20162020 and increased 0.5%decreased 0.9% as a percentage of operating revenues. The higher dollar amount of salaries, wages and benefits expense in 2021 was due primarily to 3% more company trucksincreased driver pay, including: (i) driver pay rate increases, (ii) incentive recruiting bonuses, and miles in 2017 compared to 2016(iii) minimum pay guarantees, and higher benefits expense, including group health insurance. These increases were partially offset by 20.5 million fewer company tractor miles during 2021. In January 2021, we implemented driver pay increases of approximately $10 million annually in our One-Way Truckload fleet, and studentanother pay rates, bothincrease in August of which resulted in higher payroll taxes and other payroll-related fringe benefits. When evaluated onapproximately $11 million annually. Within Dedicated, we continue to implement pay increases as needed. As a per-mile basis, driver and non-driver salaries, wages and benefits increased, which we attribute primarily to 4% higherresult, driver pay per company truckdriver mile increased 15% in 2017.2021. Non-driver salaries, wages and benefits in theour non-trucking Werner Logistics segment increased 12.8% in 2017 compared to 2016.4.1%.
We renewed our workers’ compensation insurance coverage for the policy year beginningon April 1, 2017.2021. Our coverage levels are the same as the prior policy year. We continue to maintain a self-insurance retention of $1.0$2.0 million per claim. Our workers’ compensation insurance premiums for the policy year beginning April 2017 were similar to those2021 are $0.3 million higher than the premiums for the previous policy year.

TheStrong consumer demand combined with a severely constrained driver recruiting market is challenging.presenting labor challenges for customers and carriers alike and became more challenging in 2021, as the strong freight market caused increased competition for the finite number of experienced drivers that meet our hiring standards. Several ongoing market factors persisted including a declining number of, and increased competition for, driver training school graduates, a low national unemployment rate, aging truck driver demographics and increased truck safety regulations. We proactively took manycontinue to take significant actions over the last two years to strengthen our driver recruiting and retention as we strive to make Wernerbe the preferredtruckload employer of choice, for the best drivers, including raising driver pay, loweringproviding a modern tractor and trailer fleet with the age of our truck fleet, installinglatest safety equipment and training features on all new trucks,technology, investing inand expanding our driver training schoolsschool network and collaborating with customers to improve or eliminate unproductive freight. These steps helped us to grow our fleet by nearly 5% in 2017 in this difficult driver market. In 2017, our driver turnover rate once again improved, as we achieved our lowest annual driver turnover rate in 19 years.offering a wide variety of driving positions including daily and weekly home time opportunities. We are unable to predict whether we will experience future driver shortages.shortages or maintain our current driver retention rates. If such a driver shortage were to occur and additional driver pay rate increases became necessary to attract and retain drivers, our results of operations would be negatively impacted to the extent that we could not obtain corresponding freight rate increases.
Fuel increased $43.7$88.7 million or 28.2%56.5% in 20172021 compared to 20162020 and increased 1.7%2.4% as a percentage of operating revenues due to higher average diesel fuel prices, and more company trucks and miles, partially offset by improved20.5 million fewer company tractor miles per gallon (“mpg”).in 2021. Average diesel fuel prices, in 2017excluding fuel taxes, for the full year 2021 were 3285 cents per gallon higher than in 2016,the full year 2020, a 23%64% increase.
We continue to employ measures to improve our fuel mpg includingsuch as (i) limiting trucktractor engine idle time, (ii) optimizing the speed, weight and specifications of our equipment and (iii) implementing mpg-enhancing equipment changes to our fleet including new trucks with EPA 2010 compliant engines,tractors, more aerodynamic trucktractor features, idle reduction systems, trailer tire inflation systems, trailer skirts and automated manual transmissions to reduce our fuel gallons purchased. However, fuel savings from mpg improvement is partially offset by higher depreciation expense and the additional cost of diesel exhaust fluid (required in tractors with engines that meet the 2010 EPA emission standards).fluid. Although our fuel management programs require significant capital investment and research and development, we intend to continue these and other environmentally conscious initiatives, including our active participation as an EPA SmartWay Transport Partner. The SmartWay Transport Partnership is a national voluntary program developed by the EPA and freight industry representatives to reduce greenhouse gases and air pollution and promote cleaner, more efficient ground freight transportation.
For the first eight weeks

Through February 18, the average diesel fuel price per gallon in 2022 was approximately 40 cents$1.03 higher than the average diesel fuel price per gallon in the same period of 20172021 and approximately 4288 cents higher than the average for first quarter 2017.2021.
Shortages of fuel, increases in fuel prices and petroleum product rationing can have a material adverse effect on our operations and profitability. We are unable to predict whether fuel price levels will increase or decrease in the future or the extent to which fuel surcharges will be collected from customers. As of December 31, 2017,2021, we had no derivative financial instruments to reduce our exposure to fuel price fluctuations.
Supplies and maintenance decreased $7.1increased $30.9 million or 4.1%17.5% in 20172021 compared to 20162020 and decreased 0.8% as a percentage of operating revenues. Repairs and maintenance for our tractor and trailer fleets decreased in 2017 compared to 2016 despite higher company miles driven due to a newer fleet of tractors and trailers. These decreases were partially offset by higher driver recruiting and other driver-related costs in the 2017 period.
Insurance and claims decreased $3.9 million or 4.7% in 2017 compared to 2016 and decreased 0.4%increased 0.2% as a percentage of operating revenues. The decreasehigher dollar amount of supplies and maintenance expense was due primarily to higher equipment maintenance costs, driver lodging expenses and driver sourcing costs. Our driver sourcing costs were higher due to startup costs for our new and planned driving school location additions.
Insurance and claims decreased $11.2 million or 10.2% in 20172021 compared to 2016 is2020 and decreased 1.0% as a percentage of operating revenues, due primarily the result ofto lower expense for new large dollar claims and a lower amount of unfavorable loss development on prior period large dollar claims, partially offset by higher liability insurance premiums of $7.7 million. In January 2020, one of our tractors was involved in 2017. Mosta serious accident. We self-insure for the first $10.0 million of liability coverage for this policy period, and have appropriate excess liability coverage with insurance carriers above that amount. As a result, we recorded $10.0 million of insurance and claims expense in first quarter 2020 for this accident. We also incurred insurance and claims expense of $5.1 million and $4.9 million in 2021 and 2020, respectively, for accrued interest related to a previously-disclosed adverse jury verdict rendered on May 17, 2018, which we are appealing (see Note 12 in the Notes to Consolidated Financial Statements set forth in Part II of this Form 10-K). Interest is accrued at $0.4 million per month, until such time as the outcome of our appeal is finalized. The majority of our insurance and claims expense results from our claim experience and claim development under our self-insurance program; the remainder results from insurance premiums for claims in excess of our self-insured limits.
We renewed our liability insurance policies on August 1, 20172021 and assumed additional risk exposure by increasing our self-insured retention and deductible levels. Effective on August 1, 2017, we are responsible for the first $3.0 million per claim with an annual $6.0 million aggregate for claims between $3.0 million and $5.0 million. We also have an additional $5.0 million deductible per claim for each claim between $5.0 million and $10.0 million. As a result, we are responsible for the first $10.0 million per claim until we meet the $6.0on all claims with an annual $10.0 million aggregate for claims between $3.0$10.0 million and $5.0$15.0 million. For the policy yearsyear that ended July 31, 2016 and 2017,began August 1, 2020, we were responsible for the first $2.0$10.0 million per claim with an annual $8.0 million aggregate for claims between $2.0 million and $5.0 million and an annual aggregate of $5.0 million for claims between $5.0 million and $10.0 million.no aggregates. We maintain liability insurance coverage with insurance carriers substantially in excess of the $10.0 million per claim. As a result of the higher self-insured retention and deductible amounts under the new policies, ourOur liability insurance premiums for the policy year that began August 1, 20172021 are about $3.7$7.0 million lowerhigher than premiums for the previous policy year. See Item 3 of Part I of this Form 10-K for information on our bodily injury
Depreciation and property damage coverage levels since August 1, 2014.
Depreciationamortization expense increased $7.9$4.4 million or 3.8%1.7% in 20172021 compared to 20162020 and decreased 0.1%1.3% as a percentage of operating revenues. This expense increase isrevenues due primarily to (i)depreciation and amortization on tangible and intangible assets recorded in the higher costECM and NEHDS acquisitions, partially offset by the impact of new trucks purchased compared toa change in accounting estimate that was made in the costfirst quarter 2020, which increased depreciation expense by $9.6 million in 2020. During the first quarter of used trucks that were sold over the past 12 months and (ii) the purchase of new trailers over the past 12 months to replace older used trailers which were fully depreciated. During fourth quarter 20162020, we changed the estimated life of certain truckstractors expected to be sold in 2020 to more rapidly depreciate the trucks

Rent and purchased transportation expense decreased $2.7increased $122.0 million or 0.5%23.5% in 20172021 compared to 20162020 and decreased 1.4%increased 1.5% as a percentage of operating revenues. Rent and purchased transportation expense consists mostly of payments to third-party capacity providers in the Werner Logistics segment and other non-trucking operations and payments to independent contractors in the TruckloadTTS segment. The payments to third-party capacity providers generally vary depending on changes in the volume of services generated by the Werner Logistics segment. Werner Logistics rent and purchased transportation expense increased $9.8$128.1 million as a result of higher logistics revenues, and increaseddecreased to 85.1%86.0% as a percentage of Werner Logistics revenues in 20172021 from 82.9%86.7% in 2016. Tighter carrier capacity in 2017 compared to 2016 resulted in higher purchased transportation costs for our predominantly contractual logistics business, causing the lower gross margin percentages.2020.
Rent and purchased transportation expense for the TruckloadTTS segment decreased $12.5$6.0 million in 20172021 compared to 2016.2020. This decrease is due primarily to lower payments to independent contractors in 20172021 compared to 2016,2020, resulting from a 15.6% decrease in22.6 million fewer independent contractor miles driven in 2017. This decrease was partially offset by higher2021. Higher average diesel fuel prices in 2017, which2021 also resulted in a higher reimbursement toper-mile settlement rate for independent contractors for fuel.contractors. Independent contractor miles as a percentage of total miles were 12.1%5.8% in 20172021 and 14.4%8.3% in 2016.2020. Because independent contractors supply their own tractors and drivers and are responsible for their operating expenses, the decrease in independent contractor miles as a percentage of total miles also shifted costs from the rent and purchased transportation category to other expense categories, including (i) salaries, wages and benefits, (ii) fuel, (iii) depreciation, (iv) supplies and maintenance and (v) taxes and licenses.

Challenging operating conditions continue to make independent contractor recruitment and retention difficult. Such conditions include inflationary cost increases that are the responsibility of independent contractors and a shortage of financing available to independent contractors for equipment purchases. Historically, we have been able to add company tractors and recruit additional company drivers to offset any decrease in the number of independent contractors. If a shortage of independent contractors and company drivers occurs, further increases in per-mile settlement rates (for independent contractors) and driver pay rates (for company drivers) may become necessary to attract and retain these drivers. This could negatively affect our results of operations to the extent that we would not be able to obtain corresponding freight rate increases.
Other operating expenses increased $5.5decreased $52.8 million in 20172021 compared to 20162020 and increased 0.3%decreased 2.0% as a percentage of operating revenues. Gains on sales of assets (primarily used truckstractors and trailers) are reflected as a reduction of other operating expenses and are reported net of sales-related expenses (which include costs to prepare the equipment for sale). Gains on sales of assets were $6.8$61.5 million in 2017,2021, compared to $16.4$11.3 million in 2016, which included $10.5 million in real estate gains.2020. In 2017,2021, we sold more trucksfewer tractors and fewer trailers than in 2016.2020. We realized substantially higher average gains per truck sold in 2017 compared to average losses per truck in 2016,tractor and we realized lower average gains per trailer sold in 2017 compared to 2016. The used truck pricing market remained difficult in 20172021 due to a higher than normal supply of used truckssignificantly improved pricing in the market and low buyer demand. Other operating expenses, primarily provision for doubtful accounts related toour used equipment, which we believe is a result of increased demand for previously used equipment because of production delays limiting availability of new equipment in the driver training schools and professional and consulting fees, were $4.2 million lower in 2017 than in 2016.industry.

Interest income decreased due to lower average outstanding notes receivable, which was partially offset by lower interest expense in 2017 compared to 2016 due to lower average outstanding debt.this Form 10-K).
Income Tax Expense (Benefit)
Income tax expense (benefit) decreased $106.7increased $28.9 million in 20172021 compared to 2016,2020, due primarily to the impact of federal tax law changes.

Operating Revenues
Operating revenues decreased 4.0% in 2016 compared to 2015. When comparing 2016 to 2015,For a comparison of the Truckload segment revenues decreased $110.9 million, or 6.7%, and revenuesCompany’s results of operations for the Werner Logistics segment increased $24.0 million, or 6.1%. The lower fuel prices in 2016 comparedfiscal year ended December 31, 2020 to 2015 resulted in lower fuel surcharge revenuesthe fiscal year ended December 31, 2019, see Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, in the Truckload segment.
2016 was a very challenging freight and rate year for our truckload and logistics business segments. Freight demand in the first half of 2016 was softer than the same periods of 2015 and 2014 but began to show sequential and seasonal improvement in the second half of the year. We believe part of this improvement was industry specific and part was company specific. During June 2016, to take advantage of the strengthening Dedicated market, we moved 150 trucks from One-Way Truckload into Dedicated, lessening the need to find freight for their trucks in the more challenged one-way truckload market. In September 2016, we moved an additional 100 trucks from One-Way Truckload into Dedicated.
The contractual rate market was very challenging in the first half of 2016, particularly in One-Way Truckload. An excess supply of industry trucks relative to sluggish freight demand created a market in which some customers pushed hard and obtained contractual rate decreases. At that time, we chose to exit from certain contractual business that would have required mid-to-high single digit contractual rate decreasesCompany’s Annual Report on Form 10-K for the next year since we believed that this pricingended December 31, 2020, which was not sustainable. Market conditionsfiled with the U.S. Securities and competition, however, necessitated agreeing to some flat to slightly lower contractual rates which became effective in the second half of 2016. Gradual improvement in freight volumes and transactional (non-contract) spot market rates in the second half of 2016 began to validate our pricing strategy, and in fourth quarter 2016 contract rates began to stabilize for new contracts.
Trucking revenues, net of fuel surcharge, decreased 3.9% in 2016 compared to 2015 due to a 3.8% decrease in average revenues per tractor per week, net of fuel surcharge revenues. The average number of tractors in service remained about the same in both years. Average miles per truck declined by 3.2% in 2016 compared to 2015, and average revenues per total mile, net of fuel surcharge revenues, decreased 0.6%.
The average number of tractors in service in the Truckload segment remained flat at 7,263 in 2016 compared to 7,271 in 2015. We ended 2016 with 7,100 tractors in the Truckload segment, a year-over-year decrease of 350 trucks. Our Specialized Services unit (formerly comprised of both Dedicated and Temperature Controlled), ended 2016 with 3,760 trucks (or 53% of our total Truckload segment fleet compared to 49% at the end of 2015), and One-Way Truckload ended the year with 3,340 trucks.
Trucking fuel surcharge revenues decreased 26.9% to $155.3 million in 2016 from $212.5 million in 2015 because of lower average fuel prices in 2016.
Werner Logistics revenues were generated by its four operating units and exclude revenues for full truckload shipments transferred to the Truckload segment, which are recorded as trucking revenues by the Truckload segment. Werner Logistics also recorded revenue and brokered freight expense of $1.0 million in 2016 and $1.3 million in 2015 for Intermodal drayage movements performed by the Truckload segment (also recorded as trucking revenues by the Truckload segment), and these transactions between reporting segments are eliminated in consolidation. Werner Logistics revenues increased 6.1% to $417.2 million in 2016 from $393.2 million in 2015. The Werner Logistics gross margin dollars increased 17.0% to $71.4 million in 2016 from $61.0 million in 2015, and the Werner Logistics gross margin percentage improved to 17.1% in 2016 from 15.5% in 2015. The Werner Logistics operating income percentage improved to 5.0% in 2016 from 4.3% in 2015. In 2016, Werner Logistics achieved growth in our truck brokerage and intermodal solutions despite the challenged logistics freight market.
Operating Expenses
Our operating ratio was 93.7% in 2016 compared to 90.4% in 2015. Expense items that impacted the overall operating ratio are describedExchange Commission on the following pages. The tables on pages 15 through 16 show the Consolidated Statements of Income in dollars and as a percentage of total operating revenues and the percentage increase or decrease in the dollar amounts of those items compared to the prior year, as well as the operating ratios, operating margins and certain statistical information for our two reportable segments, Truckload and Werner Logistics.
Salaries, wages and benefits decreased $3.8 million or 0.6% in 2016 compared to 2016 but increased 1.1% as a percentage of operating revenues. The lower dollar amount of salaries, wages and benefits expense was due primarily to fewer company trucks and miles in 2016 compared to 2015, partially offset by higher driver mileage pay rates (including a pay increase effective January 1, 2016, for approximately 20% of our company drivers and prior driver pay increases in multiple Dedicated fleets). When evaluated on a per-mile basis, driver and non-driver salaries, wages and benefits increased, which we attribute primarily to 7% higher driver pay per company truck mile in 2016. Non-driver salaries, wages and benefits in the non-trucking Werner Logistics segment increased 20.3% in 2016 compared to 2015.

We renewed our workers’ compensation insurance coverage for the policy year beginning April 1, 2016. Our coverage levels are the same as the prior policy year. We continue to maintain a self-insurance retention of $1.0 million per claim. Our workers’ compensation insurance premiums for the policy year beginning April 2016 were similar to those for the previous policy year.
The driver recruiting market remained challenging in 2016. Several ongoing market factors persisted including a declining number of, and increased competition for, driver training school graduates, a low national unemployment rate, aging truck driver demographics and increased truck safety regulations. We took many significant actions in 2016 to strengthen our driver recruiting and retention to make Werner the preferred choice for the best drivers, including raising driver pay, lowering the age of our truck fleet, installing safety and training features on all new trucks, tightening our driver hiring standards and investing in our driver training schools. In 2016, we achieved our lowest driver turnover rate in 17 years.
Fuel decreased $49.5 million or 24.2% in 2016 compared to 2015 and decreased 2.1% as a percentage of operating revenues due to (i) lower average diesel fuel prices, (ii) fewer company trucks and miles and (iii) improved miles per gallon (“mpg”). Average diesel fuel prices in 2016 were 29 cents per gallon lower than in 2015, a 17% decrease.
During 2016, we continued to employ measures to improve our fuel mpg and invest in fuel saving equipment solutions, which were also intended to lessen environmental impact. These measures resulted in an improvement in mpg in 2016 compared to 2015, however, fuel savings from the mpg improvement was partially offset by higher depreciation expense and the additional cost of diesel exhaust fluid.
Supplies and maintenance decreased $18.7 million or 9.8% in 2016 compared to 2015 and decreased 0.6% as a percentage of operating revenues. Repairs and maintenance decreased in 2016 compared to 2015 due to our younger tractor and trailer fleet and fewer company driver miles driven in 2016.
Taxes and licenses decreased $4.1 million or 4.6% in 2016 compared to 2015 and did not change as a percentage of operating revenues. Federal and state diesel fuel taxes were lower in 2016 than in 2015 because of fewer company driver miles and a higher mpg in 2016. An improved mpg results in fewer gallons of diesel fuel purchased and consequently less fuel taxes paid.
Insurance and claims increased $3.0 million or 3.7% in 2016 compared to 2015 and increased 0.3% as a percentage of operating revenues. The increase in 2016 compared to 2015 is primarily the result of unfavorable loss development on prior period large dollar claims. We renewed our liability insurance policies on August 1, 2016, and continued to be responsible for the first $2.0 million per claim with an annual $8.0 million aggregate for claims between $2.0 million and $5.0 million and an annual aggregate of $5.0 million for claims in excess of $5.0 million and less than $10.0 million. Our liability and cargo insurance premiums for the policy year that began August 1, 2016 were about $3.5 million higher than premiums for the previous policy year. The market for excess trucking liability was extremely difficult in 2016 compared to 2015, as insurance carriers had either exited the market or increased premium rates due to the increasing plaintiff awards in the industry.
Depreciation increased $16.5 million or 8.5% in 2016 compared to 2015 and increased 1.2% as a percentage of operating revenues. This expense increase is due primarily to (i) the higher cost of new trucks purchased compared to the cost of used trucks that were sold over the past 12 months, (ii) the purchase of new trailers over the past 12 months to replace older used trailers which were fully depreciated and (iii) a change during fourth quarter 2016 in the estimated life of certain trucks to more rapidly depreciate the trucks to their residual values due to the weak used truck market. The effect of this change in accounting estimate was to increase 2016 depreciation expense by $4.1 million.
Rent and purchased transportation expense increased $31.7 million or 6.6% in 2016 compared to 2015 and increased 2.6% as a percentage of operating revenues. Werner Logistics rent and purchased transportation expense increased $13.6 million, which corresponds to the higher Werner Logistics revenues, but decreased to 82.9% of Werner Logistics revenues in 2016 from 84.5% in 2015. The improved gross margin percentage is the result of on-going efforts to match contractual customer consistent freight with our strategic carrier partners’ capacity and then utilize the available capacity in the market to cover transactional volume.
Rent and purchased transportation expense for the Truckload segment increased $18.3 million in 2016 compared to 2015. This increase is due primarily to higher payments to independent contractors in 2016 compared to 2015, resulting from a November 2015 increase in the per-mile settlement rate for certain independent contractors. This increase was partially offset by lower average diesel fuel prices in 2016, which resulted in lower reimbursement to independent contractors for fuel. Independent contractor miles as a percentage of total miles were 14.4% in 2016 and 11.9% in 2015.
Communications and utilities increased $1.0 million or 6.5% in 2016 compared to 2015 and increased 0.1% as a percentage of operating revenues. The increase is due to higher equipment tracking expenses and higher communication costs in 2016.
Other operating expenses increased $13.8 million in 2016 compared to 2015 and increased 0.7% as a percentage of operating revenues. Gains on sales of assets were $16.4 million in 2016, including $10.5 million from sales of real estate, compared to $23.2

million in 2015, which included $0.9 million in real estate gains. In 2016, we sold fewer trucks and more trailers than in 2015 and realized average losses per truck and higher average gains per trailer sold. The used truck pricing market became increasingly difficult as 2016 progressed due to a higher than normal supply of used trucks in the market and low buyer demand. Other operating expenses, primarily provision for doubtful accounts related to the driver training schools and professional and consulting fees, were $7.0 million higher in 2016 than in 2015.
Other Expense (Income)
Other expense (income) decreased $0.7 million in 2016 compared to 2015 and remained flat as a percentage of operating revenues due primarily to higher interest income on notes receivable. Interest expense was higher in 2016 compared to 2015 due to higher average outstanding debt.
Income Taxes
Our effective income tax rate (income taxes expressed as a percentage of income before income taxes) decreased to 37.9% for 2016 from 38.5% in 2015. The lower income tax rate in 2016 is primarily attributed to favorable tax adjustments for the remeasurement of uncertain tax positions in 2016.February 24, 2021.
Liquidity and Capital Resources:

We closely manage our liquidity and capital resources. Our liquidity requirements depend on key variables, including the level of investment needed to support business strategies, the performance of the business, capital expenditures, borrowing arrangements, and working capital management. Capital expenditures, stock repurchases, and dividend payments are components of our cash flow and capital management strategy, which to a large extent, can be adjusted in response to economic and other changes in the business environment. Management’s approach to capital allocation focuses on investing in key priorities that support our business and growth strategies and providing shareholder returns, while funding ongoing operations.
During the year endedManagement believes our financial position at December 31, 2017,2021 is strong. As of December 31, 2021, we had $54.2 million of cash and cash equivalents and over $1.3 billion of stockholders’ equity. Cash is invested primarily in government portfolio money market funds. In addition, we have a $300.0 million and a $200.0 million credit facility, for which our total available borrowing capacity was $115.1 million as of December 31, 2021 (see Note 8 in the Notes to Consolidated Financial Statements under Item 8 of Part II of this Form 10-K for information regarding our credit agreements). We believe our liquid assets, cash generated from operating activities, and borrowing capacity under our existing credit facilities will provide sufficient funds to meet our cash requirements and our planned shareholder returns for the foreseeable future.
Our material cash requirements include the following contractual and other obligations.
Debt Obligations and Interest Payments – As of December 31, 2021, we had outstanding debt with an aggregate principal amount of $427.5 million, with $5.0 million payable within 12 months. Future interest payments associated with our debt obligations are estimated to be $14.6 million through 2024, with $6.2 million payable within 12 months. See Note 8 in the Notes to Consolidated Financial Statements under Item 8 of Part II of this Form 10-K for further detail of our debt and the timing of expected future principal payments.
Operating Leases – We have entered into operating leases primarily for real estate. As of December 31, 2021, we had fixed lease payment obligations of $32.1 million, with $7.0 million payable within 12 months. See Note 5 in the Notes to

Consolidated Financial Statements under Item 8 of Part II of this Form 10-K for further detail of our lease obligations and the timing of expected future payments.
Purchase Obligations – As of December 31, 2021, we have committed to property and equipment purchases of approximately $163.2 million within the next 12 months.
In addition to our cash requirements, the Board of Directors has authorized us to deliver value to shareholders through stock repurchases and quarterly cash dividends. The stock repurchase program does not obligate the Company to acquire any specific number of shares. We plan to continue paying a quarterly dividend, which currently results in a cash outlay of slightly less than $8 million per quarter.
Cash Flows
We generated cash flow from operations of $281.8$332.8 million a 9.8% decrease ($30.6 million),during 2021 compared to the year ended December 31, 2016. This$445.9 million during 2020.

Cash flow from operations decreased $58.0 million in 2016 from 2015, or 15.7%. This decrease is attributed primarily to a $44.6 million decrease in net income and a $15.4 million decrease from general working capital activities (including accounts receivable and accounts payable).2020 employer payroll tax payments as permitted under the CARES Act.

This decrease occurred after we completed a significant reinvestment in our tractor and trailer fleet in 2015 and 2016. As of December 31, 2017, we were committed to property and equipment purchases of approximately $185.3 million.2020.

The timing and amount of such purchases depends onupon economic and stock market conditions and other factors. On November 9, 2021, our Board of Directors approved a new stock repurchase program under which the Company is authorized to repurchase up to 6,000,000 shares of its common stock. On the same day, our Board of Directors withdrew the previous stock repurchase authorization, which had 1,496,983 shares remaining available for repurchase. As of December 31, 2017,2021, the Company had purchased 3,287,291977,886 shares pursuant to our current Board of Directors repurchasethe new authorization and had 4,712,7095,022,114 shares remaining available for repurchase.

Table of December 31, 2017, we had $75.0 million of debt outstanding and over $1.1 billion of stockholders’ equity. As of December 31, 2017, we had a total of $325.0 million of credit pursuant to three credit facilities (see Note 2 in the Notes to Consolidated Financial Statements under Item 8 of Part II of this Form 10-K for information regarding our credit agreements as of December 31, 2017), of which we had borrowed $75.0 million. The remaining $250.0 million of credit available under these facilities at December 31, 2017 is reduced by the $39.6 million in stand-by letters of credit under which we are obligated. These stand-by letters of credit are primarily required as security for insurance policies. Based on our strong financial position, management does not foresee any significant barriers to obtaining sufficient financing, if necessary.Contents

We had an unsecured line of credit of $75 million with U.S. Bank, N.A., which will expire on July 13, 2020. We also had a $75 million credit facility with BMO Harris Bank, N.A., which will expire on March 5, 2020. Borrowings under these credit facilities and term note bear variable interest based on the London Interbank Offered Rate (“LIBOR”). As of December 31, 2017, we had $75 million outstanding under the term commitment at a variable rate of 2.08%, which is effectively fixed at 2.5% with an interest rate swap agreement. Interest payments on debt are based on the debt balance and interest rate at December 31, 2017. The borrowing capacity under these credit facilities is further reduced by the amount of stand-by letters of credit under which we are obligated. The stand-by letters of credit are primarily required for insurance policies. The unused lines of credit are available to us in the event we need financing for the replacement of our fleet or for other significant capital expenditures. Management believes our financial position is strong, and we therefore expect that we could obtain additional financing, if necessary. Property and equipment purchase commitments relate to committed equipment expenditures, primarily for revenue equipment. As of December 31, 2017, we had recorded a $2.9 million liability for unrecognized tax benefits. We are unable to reasonably determine when the $2.9 million categorized as “period unknown” will be settled.
Off-Balance Sheet Arrangements:
In 2017, we did not have any non-cancelable revenue equipment operating leases or other arrangements that meet the definition of an off-balance sheet arrangement.
Critical Accounting Policies and Estimates:
The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the (i) reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and (ii) reported amounts of revenues and expenses during the reporting period. We evaluate these estimates on an ongoing basis as events and circumstances change, utilizing historical experience, consultation with experts and other methods considered reasonable in the particular circumstances. Actual results could differ from those estimates and may significantly impact our results of operations from period to period. It is also possible that materially different amounts would be reported if we used different estimates or assumptions.

The most critical accounting policies and estimates that require us to make significant judgments and estimates and affect our financial statements include the following:
Depreciation and impairment of tractors and trailers. We operate a significant number of tractors and trailers in connection with our business and must select estimated useful lives and salvage values for calculating depreciation. Depreciable lives of tractors and trailers range from 80 months to 12 years. Estimates of salvage value at the expected date of trade-in or sale are based on the expected market values of equipment at the time of disposal. We consider our experience with similar assets, conditions in the used revenue equipment market and operational information such as average annual miles. We believe that these methods properly spread the costs over the useful life of the assets. We continually monitor the adequacy of the lives and salvage values used in calculating depreciation expense and adjust these assumptions appropriately when warranted. We review our long-lived assets for impairment whenever events or circumstances indicate the carrying amount of a long-lived asset may not be recoverable. An impairment loss would be recognized if the carrying amount of the long-lived asset is not recoverable and the carrying amount exceeds its fair value.
Estimates of accrued liabilities for insurance and claims for liability and physicalbodily injury, property damage losses and workers’ compensation.compensation is a critical accounting estimate that requires us to make significant judgments and estimates and affects our financial statements. The insuranceaccruals for bodily injury, property damage and claims accrualsworkers’ compensation (current and non-current) are recorded at the estimated ultimate payment amounts and are based upon individual case estimates (including negative development) and actuarial estimates of loss development for reported losses and incurred-but-not-reported losses using loss development factors based upon past experience. In order to determine the loss development factors, we make judgments relating to the comparability of historical claims to current claims. These judgments consider the nature, frequency, severity, and age of claims, and industry, regulatory, and company-specific trends impacting the development of claims. An independent actuary reviews our calculation of the undiscounted self-insurance reserves for bodily injury and property damage claims and workers’ compensation claims at year-end. The actual cost to settle our self-insured claim liabilities can differ from our reserve estimates because of a number of uncertainties, including the inherent difficulty in estimating the severity of a claim and the potential amount to defend and settle a claim.
Accounting for income taxes. Significant management judgment is required to determine (i) the provision for income taxes, (ii) whether deferred income taxes will be realized in full or in part and (iii) the liability for unrecognized tax benefits related to uncertain tax positions. Deferred income tax assets and liabilities are measured using enacted tax rates that are expected to apply to taxable income We have not made any material changes in the years when those temporary differences are expectedaccounting methodology or assumptions used to be recovered or settled. When it is more likely that all or some portion of specific deferred income tax assets will not be realized, a valuation allowance must be establishedcalculate our accrued liabilities for the amount of deferred income tax assets that are determined not to be realizable. On December 22, 2017, the Tax Act was enacted, which lowered the federal corporate income tax rate to 21% from 35% effective January 1, 2018. In accordance with the SEC’s Staff Accounting Bulletin No. 118, the Company has recognized the provisional tax impact related to the revaluation of deferred income tax assetsinsurance and liabilitiesclaims for bodily injury, property damage, and included the amount in its consolidated financial statements for the year ended December 31, 2017.  The ultimate impact may differ from the provisional amount due to, among other things, additional analysis, changes in interpretations and assumptions the Company has made, and additional regulatory guidance that may be issued.  The accounting is expected to be completed when the Company’s 2017 income tax returns are filed later in 2018. We believe that we have adequately provided for our future tax consequences based upon current facts and circumstances and current tax law. However, should our positions be challenged, different outcomes could result and have a significant impact on our results of operations.
Inflation:
Inflation may impact our operating costs. A prolonged inflation period could cause rises in interest rates, fuel, wages and other costs. These inflationary increases could adversely affect our results of operations unless freight rates could be increased correspondingly. However, the effect of inflation has been minimal overworkers’ compensation during the past three years. At December 31, 2021 and 2020, we had an accrual of $309.8 million and $308.6 million, respectively, for estimated insurance and claims for (i) cargo loss and damage, (ii) bodily injury and property damage, (iii) group health, and (iv) workers’ compensation claims not covered by insurance. A 10% change in actuarial estimates at December 31, 2021, would have changed our insurance and claims accrual by approximately $29.3 million.

ITEM 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
We are exposed to market risk from changes in interest rates, commodity prices, and foreign currency exchange rates, and interest rates.
Commodity Price Risk
The price and availability of diesel fuel are subject to fluctuations attributed to changes in the level of global oil production, refining capacity, regulatory changes, seasonality, weather and other market factors. Historically, we have recovered a majority, but not all, of fuel price increases from customers in the form of fuel surcharges. We implemented customer fuel surcharge programs with most of our customers to offset much of the higher fuel cost per gallon. However, we do not recover all of the fuel cost increase through these surcharge programs. We cannot predict the extent to which fuel prices will increase or decrease in the future or the extent to which fuel surcharges could be collected. As of December 31, 2017,2021, we had no derivative financial instruments to reduce our exposure to fuel price fluctuations.
Foreign Currency Exchange Rate Risk
We conduct business in several foreign countries, including Mexico, Canada, China and Australia.primarily in Mexico. To date, most foreign revenues are denominated in U.S. Dollars, and we receive payment for foreign freight services primarily in U.S. Dollars to reduce direct

foreign currency risk. Assets and liabilities maintained by a foreign subsidiary company in the local currency are subject to foreign exchange gains or losses. Foreign currency translation gains and losses primarily relate to changes in the value of revenue equipment owned by a subsidiary in Mexico, whose functional currency is the Peso. Foreign currency translation gains were $0.5 million in 2017, and foreign currency translation losses were $4.2$1.4 million in 2016 and $3.9$2.9 million in 2015,for the years ended December 31, 2021 and 2020, respectively, and were recorded in accumulated other comprehensive loss within stockholders’ equity in the Consolidated Balance Sheets.consolidated balance sheets. The exchange rate between the Mexican Peso and the U.S. Dollar was 19.74 20.58 Pesos to $1.00 at December 31, 20172021 compared to 20.66 19.95 Pesos to $1.00 at December 31, 2016 and 17.21 Pesos to $1.00 at December 31, 2015.

2020.
Interest Rate Risk
We manage interest rate exposure through a mix of variable interest rate debt and interest rate swap agreements. We had $75.0$150 million of variable interest rate debt outstanding at December 31, 2017,2021, for which the interest rate is effectively fixed at 2.5%2.34% through September 2019May 2024 with antwo interest rate swap agreement.agreements to reduce our exposure to interest rate increases. In addition, we had $180.0 million of variable interest rate debt outstanding at December 31, 2021. Interest rates on the variable rate debt and our unused credit facilities are based on the LIBOR. See Note 8 in the Notes to Consolidated Financial Statements under Item 8 of Part II of this Form 10-K for further detail of our debt. Assuming this level of borrowing, a hypothetical one-percentage point increase in the LIBOR (see Contractual Obligations and Commercial Commitments). Increases in interest rates could impactrate would increase our annual interest expense by approximately $1.8 million.
Due to uncertainty surrounding the suitability and sustainability of the London Interbank Offered Rate (LIBOR), central banks and global regulators have called for financial market participants to prepare for the discontinuation of LIBOR. On March 5, 2021, ICE Benchmark Administration ratified its proposal on future borrowings. Asceasing publication of one-week and two-month settings of the USD LIBOR benchmark at the end of December 31, 2017, we had one effective interest2021, and ceasing publication of the remaining overnight and one-, three-, six- and 12-month USD LIBOR settings at the end of the June 2023. LIBOR is a widely-referenced benchmark rate, swap agreementand our unsecured credit facilities are referenced to LIBOR. We are communicating with our banks regarding the eventual transition to a notional amount of $75.0 million to reduce our exposure to interest rate increases.

Werner Enterprises, Inc.:
Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheets of Werner Enterprises, Inc. and subsidiaries (the Company) as of December 31, 20172021 and 2016, and2020, the related consolidated statements of income, comprehensive income, stockholders’ equity and temporary equity - redeemable noncontrolling interest, and cash flows for each of the years in the three‑year period ended December 31, 2017,2021, and the related notes and financial statement schedule II listed in the Index in Item 15(a)(2) (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 20172021 and 2016,2020, and the results of its operations and its cash flows for each of the years in the three-yearthree‑year period ended December 31, 2017,2021, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2017,2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, (COSO), and our report dated February 27, 2018,28, 2022 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Evaluation of insurance and claims accruals
As discussed in Note 1 to the consolidated financial statements, the Company estimates the insurance and claims accruals related to (1) cargo loss and damage, (2) bodily injury and property damage, (3) group health, and (4) workers’ compensation claims not covered by insurance. The Company’s current and non-current insurance and claims accruals were $72.6 million and $237.2 million, respectively. The accruals specifically for bodily injury, property damage, and workers’ compensation are based upon individual case estimates and actuarial estimates of loss development for reported losses and incurred-but-not-reported losses using loss development factors based upon past experience. In order to determine the loss development factors, the Company makes judgments relating to the comparability of historical claims to current claims. These judgments consider the nature, frequency, severity and age of claims, and industry, regulatory, and company-specific trends impacting the development of claims. The Company has an independent actuary review their calculation of these undiscounted insurance and claims accruals.
We identified the evaluation of the Company’s insurance and claims accruals related to bodily injury, property damage, and workers’ compensation claims not covered by insurance as a critical audit matter. Specifically, evaluating the loss development factors used to determine these insurance and claims accruals involved a high degree of complexity and subjectivity. In addition, specialized skills were needed to evaluate the Company’s models to calculate these undiscounted insurance and claims accruals.
The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to these insurance and claims accruals, including controls related to the determination of loss development factors used to determine these insurance and claims accruals. We involved actuarial professionals with specialized skills and knowledge who assisted in:
assessing the models used by the Company to determine these insurance and claims accruals for consistency with generally accepted actuarial standards
assessing the determination of loss development factors used in the models for consistency with historical Company data and industry, regulatory, and company-specific trends
developing an independent expectation of the Company’s insurance and claims accruals and comparing to the Company’s estimate.
We tested historical claims paid and claims reported, but not paid, that are used as an input to the Company’s models to calculate these insurance and claims accruals for consistency with data used in the prior year. We tested actual claims paid and claims reported, but not paid, for the current year that are used as an input to the Company’s models to calculate these insurance and claims accruals for consistency with the Company’s actual claims paid and claims reported, but not paid. We compared the Company’s prior period insurance and claims accruals to actual claims in the current period to assess the Company’s ability to accurately estimate costs.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
NaturePrinciples of BusinessConsolidation: The accompanying consolidated financial statements include the accounts of Werner Enterprises, Inc. (theand its subsidiaries (collectively, the “Company”). All significant intercompany accounts and transactions relating to these entities have been eliminated.
Nature of Business: The Company is a truckload transportation and logistics companyprovider operating under the jurisdiction of the U.S. Department of Transportation, similar governmental transportation agencies in the foreign countries in which we operate and various U.S. state regulatory authorities. ForOur ten largest customers comprised 49% of our revenues for the years ended December 31, 2017, 20162021 and 2015, our ten2020, and 41% for the year ended December 31, 2019. Our largest customers comprised 43%, 43%customer, Dollar General, accounted for 14% and 45%, respectively,12% of our revenues.total revenues in 2021 and 2020, respectively. Revenues generated by Dollar General are reported in both of our reportable operating segments. No single customer generated more than 8%9% of the Company’sour total revenues in 2017, 2016, and 2015.2019.
Principles of Consolidation: The accompanying consolidated financial statements include the accounts of Werner Enterprises, Inc. and our majority-owned subsidiaries. All significant intercompany accounts and transactions relating to these majority-owned entities have been eliminated.
Use of Management Estimates: The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the (i) reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and (ii) reported amounts of revenues and expenses during the reporting period. The most significant estimates that affect our financial statements include the accrued liabilities for insurance and claims, useful lives and salvage values of property and equipment, accrued liabilities for insurance and claims, estimates for income taxes and the allowance for doubtful accounts. Actual results could differ from those estimates.
Cash and Cash Equivalents: We consider all highly liquid investments, purchased with a maturity of three months or less, to be cash equivalents. Accounts at banks with an aggregate excess of the amount of checks issued over cash balances are included in current liabilities in the Consolidated Balance Sheets,consolidated balance sheets, and changes in such accounts are reported as a financing activity in the Consolidated Statementsconsolidated statements of Cash Flows.cash flows.
Trade Accounts Receivable: We record trade accounts receivable at the invoiced amounts, net of an allowance for doubtful accounts. The allowanceaccounts for doubtful accounts is our estimate of the amount of probable credit losses and revenue adjustments in our existing accounts receivable.potentially uncollectible receivables. We review the financial condition of customers for granting credit and determine the allowance based on analysis of individual customers’ financial condition, historical write-off experience and national economic conditions. We evaluate the adequacy of our allowance for doubtful accounts quarterly. Past due balances over 90 days and exceeding a specified amount are reviewed individually for collectibility. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. We do not have any off-balance-sheet credit exposure related to our customers.
Inventories and Supplies: Inventories and supplies are stated at the lower of average cost and net realizable value and consist primarily of revenue equipment parts, tires, fuel and supplies. Tires placed on new revenue equipment are capitalized as a part of the equipment cost. Replacement tires are expensed when placed in service.
Property, Equipment, and Depreciation: Additions and improvements to property and equipment are capitalized at cost, while maintenance and repair expenditures are charged to operations as incurred. Gains and losses on the sale or exchange of equipment are recorded in other operating expenses.
Depreciation is calculated based on the cost of the asset, reduced by the asset’s estimated salvage value, using the straight-line method. Accelerated depreciation methods are used for income tax purposes. The lives and salvage values assigned to certain assets for financial reporting purposes are different than for income tax purposes. For financial reporting purposes, assets are generally depreciated using the following estimated useful lives and salvage values:
LivesSalvage Values
Building and improvements30 years0%
Tractors80 months0%$0 - $10,000
Trailers12 years$1,000 - $6,000
Service and other equipment3-10 years0%

The effect of this change in accounting estimate

was a $9.6 million increase to (i) increase 20162020 depreciation expenseexpense. These trucks continued to depreciate at the same higher rate per truck, until all were sold in 2020.
Goodwill: Goodwill represents the excess of cost over the fair value of net identifiable tangible and decrease operatingintangible assets acquired in a business combination and is allocated to reporting units that are expected to benefit from the combination. Goodwill is not amortized, but rather is tested for impairment annually in October, or more frequently if indicators of a potential impairment exist. Impairment exists when the carrying amount of a reporting unit that includes goodwill exceeds its fair value, resulting in an impairment charge for the excess up to the amount of goodwill allocated to the reporting unit. To test goodwill for impairment, we have the option to first perform a qualitative assessment to determine if it is more likely than not that the carrying amount of a reporting unit exceeds its fair value.If a qualitative test indicates a potential for impairment, a quantitative impairment test must be performed. Alternatively, we may bypass the qualitative assessment and perform a quantitative impairment test. A qualitative assessment considers relevant events and circumstances such as macroeconomic, industry, and market conditions; legal, regulatory, and competitive environments; and overall financial performance. For a quantitative impairment test, we estimate the fair values of the goodwill reporting units and compare it to their carrying values. The estimated fair values of the reporting units are established using a combination of the income by $4.1 million and (ii) increase 2017 depreciation expensemarket approaches.Our first annual goodwill impairment test is scheduled to be performed in October 2022.As of December 31, 2021, there were no indications of goodwill impairment.
Amortization of Intangible Assets: Intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives, ranging from ten to 12 years.
Long-Lived Assets and decrease operating income by $3.4 million. We completed the sale of these specific trucks in 2017.

Long-LivedIntangible Assets: We review our long-lived assets and finite-lived intangible assets for impairment whenever events or circumstances indicate the carrying amount of a long-lived assetsuch assets may not be recoverable. If based on that review, changes in circumstances indicate that the carrying amount of such assets may not be recoverable, we evaluate recoverability by comparing the undiscounted cash flows associated with the asset to the asset's carrying amount. We also evaluate the remaining useful lives of intangible assets to determine if events or trends warrant a revision to the remaining period of amortization. An impairment loss would be recognized if the carrying amount of the long-lived asset or intangible asset is not recoverable and the carrying amount exceeds its fair value. For long-lived assets classified as held and used, the carrying amount is not recoverable when the carrying value of the long-lived asset exceeds the sum of the future net cash flows. We do not separately identify assets by operating segment because tractors and trailers are routinely transferred from one operating fleet to another. As a result, none of our long-lived assets have identifiable cash flows from use that are largely independent of the cash flows of other assets and liabilities. Thus, the asset group used to assess impairment would include all of our assets.
Insurance and Claims Accruals: Insurance and claims accruals (both current and non-current) reflect the estimated cost (including estimated loss development, incurred-but-not-reported losses and loss adjustment expenses) for (i) cargo loss and damage, (ii) bodily injury and property damage, (iii) group health and (iv) workers’ compensation claims not covered by insurance. The costs for cargo, bodily injury and property damage insurance and claims are included in insurance and claims expense in the Consolidated Statementsconsolidated statements of Income;income; the costs of group health and workers’ compensation claims are included in salaries, wages and benefits expense. The insurance and claims accruals are recorded at the estimated ultimate payment amounts. Such insuranceThe accruals for bodily injury, property damage and claims accrualsworkers’ compensation are based upon individual case estimates (including negative development) and actuarial estimates of loss development for reported losses and incurred-but-not-reported losses using loss development factors based upon past experience. In order to determine the loss development factors, we make judgments relating to the comparability of historical claims to current claims. These judgments consider the nature, frequency, severity, and age of claims, and industry, regulatory, and company-specific trends impacting the development of claims. Actual costs related to insurance and claims have not differed materially from estimated accrued amounts for all years presented. An independent actuary reviews our calculation of the undiscounted self-insurance reserves for bodily injury and property damage claims and workers’ compensation claims at year-end.
We renewed our liability insurance policies on August 1, 2017,2021 and effectiveare responsible for the first $10.0 million per claim on all claims with an annual $10.0 million aggregate for claims between $10.0 million and $15.0 million. For the policy year that date, ourbegan August 1, 2020, we were responsible for the first $10.0 million per claim with no aggregates. Our self-insured retention (“SIR”) and deductible amount iswas $3.0 million, plus administrative expenses, for each occurrence involving bodily injury or property damage, with an additional $5.0 million deductible per claim for each claim between $5.05.0 million and $10.0 million. Our SIR/deductible was $2.0 million, for policy years sincefrom August 1, 2004. We are2017 through July 31, 2020, and we were also responsible for varying annual aggregate amounts of liability for claims in excess of the SIR/deductible (see page 10). Liability claims deductible. We maintain liability insurance coverage with insurance carriers in excess of these aggregates are covered under premium-based policies (issued by insurance companies) to coverage levels that our management considers adequate.the $10.0 million per claim. We are also responsible for administrative expenses for each occurrence involving bodily injury or property damage.
Our SIR for workers’ compensation claims is $1.0$2.0 million per claim, with premium-based coverage (issued by insurance coveragecompanies) for claims exceeding this amount. Our SIR for workers’ compensation claims increased from $1.0 million to $2.0

million per claim on April 1, 2020. We also maintain a $26.6$25.6 million bond for the State of Nebraska and a $6.9$13.4 million bond for our workers’ compensation insurance carrier.
Under these insurance arrangements, we maintained $39.6$43.0 million in letters of credit as of December 31, 2017.2021.
Revenue Recognition: The Consolidated Statementsconsolidated statements of Incomeincome reflect recognition of operating revenues (including fuel surcharge revenues) and related direct costs whenover time as control of the shipmentpromised services is delivered.transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those services. For shipments where a third-party capacity provider (including independent contractors under contract with us) is utilized to provide some or all of the service, and we (i)evaluate whether we are the primary obligor in regard to the shipment delivery, (ii) establish customer pricing separately from carrier rate negotiations, (iii) generally have discretion in carrier selection and/principal (i.e., report revenues on a gross basis) or (iv) have credit riskagent (i.e., report revenues on the shipment, we record both revenues for the dollar value of services we bill to the customer and rent and purchased transportation expense for transportation costs we pay to the third-party provider upon the shipment’s delivery. In the absence of the conditions listed above, we record revenuesa net of those expenses related to third-party providers.basis).
Foreign Currency Translation: Local currencies are generally considered the functional currencies outside the United States. Assets and liabilities are translated at year-end exchange rates for operations in local currency environments. Foreign revenues and expense items denominated in the functional currency are translated at the average rates of exchange prevailing during the year. Foreign currency translation adjustments reflect the changes in foreign currency exchange rates applicable to the net assets of the foreign operations. Foreign currency translation adjustments are recorded in accumulated other comprehensive loss within stockholders’ equity in the Consolidated Balance Sheetsconsolidated balance sheets and as a separate component of comprehensive income in the Consolidated Statementsconsolidated statements of Comprehensive Income.comprehensive income.
Income Taxes: Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using the enacted tax rates that are expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred income tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
In accounting for uncertain tax positions, we recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. We recognize interest and penalties directly related to income tax matters in income tax expense.

Common Stock and Earnings Per Share: Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income by the weighted average number of common shares outstanding plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include outstanding stock options and restricted stock awards. There are no differences in the numerators of our computations of basic and diluted earnings per share for any periods presented. The computation of basic and diluted earnings per share is shown below (in thousands, except per share amounts).

There were no options to purchase shares of common stock that were outstanding during the periods indicated above that were excluded from the computation of diluted earnings per share because the option purchase price was greater than the average market price of the common shares during the period. Performance awards are excluded from the calculation of dilutive potential common shares until the threshold performance conditions have been satisfied.
Equity Compensation: We have an equity compensation plan that provides for grants of non-qualified stock options, restricted stock and units (“restricted stock unitsawards”), performance awards and stock appreciation rights to our associates and directors. We apply the fair value method of accounting for equity compensation awards. Issuances of stock upon an exercise of stock options or vesting of restricted stock are made from treasury stock; shares reacquired to satisfy tax withholding obligations upon vesting of restricted stock are recorded as treasury stock. Grants of stock options, restricted stock, and performance awards vest in
36

increments, and we recognize compensation expense over the requisite service period of each award. We accrue compensation expense for performance awards for the estimated number of shares expected to be issued using the most current information available at the date of the financial statements. If the performance objectives are not met, no compensation expense will be recognized, and any previously recognized compensation expense will be reversed. We account for forfeitures in the period in which they occur.
Comprehensive Income: Comprehensive income consists of net income and other comprehensive income (loss). Other comprehensive income (loss) refers to revenues, expenses, gains and losses that are not included in net income, but rather are recorded directly in stockholders’ equity. For the years ended December 31, 2017, 20162021, 2020 and 2015,2019, comprehensive income consists of net income, foreign currency translation adjustments and change in fair value of interest rate swap.swaps. The components of accumulated other comprehensive loss reported in the consolidated balance sheets as of December 31, 2021 and 2020, consisted of foreign currency translation adjustments of $18.6 million and $17.2 million, respectively, and changes in fair value of interest rate swaps, net of tax, of $2.0 million and $5.6 million, respectively.
New Accounting Pronouncements Adopted:In July 2015,December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-11, “Inventory:2019-12, “Income Taxes (Topic 740): Simplifying the Measurement of Inventory,Accounting for Income Taxes,” which requires inventoryreduces complexity in accounting for income taxes by removing certain exceptions to be recorded at the lowergeneral principles stated in Topic 740 and by clarifying and amending existing guidance to improve consistent application of average cost and net realizable value (insteadsimplify other areas of lower of cost or market).Topic 740. The Company adopted ASU No. 2015-112019-12 as of January 1, 2017.2021. Upon adoption, this update had no effect on our consolidated financial position, results of operations, orand cash flows.
In March 2016, the FASB issued ASU No. 2016-09, “Compensation - Stock Compensation: Improvements to Employee Share-Based Payment Accounting,” to simplify several aspects of the accounting for share-based payment transactions. The new update requires excess tax benefits and tax deficiencies to be recorded in the consolidated statements of income as a component of income tax expense when share-based awards vest or are settled. The update also eliminates the requirement to reclassify cash flows related to excess tax benefits from operating activities to financing activities on the consolidated statements of cash flows. The standard also provides an accounting policy election to account for forfeitures as they occur and now allows for withholding up to the maximum statutory tax rate on certain share-based awards without triggering liability accounting.
The Company adopted ASU No. 2016-09 as of January 1, 2017. Upon adoption, share-based payment excess tax benefits and tax deficiencies are recognized in the consolidated statements of income as a component of income tax expense, rather than additional paid-in capital as previously recognized. The Company elected to report excess tax benefits as operating activities in the consolidated statements of cash flows on a prospective basis, and prior period amounts have not been adjusted. The Company also elected to use actual forfeitures to determine the amount of share-based compensation expense to be recognized. This change was applied on a modified retrospective basis and resulted in a $0.3 million decrease to retained earnings in first quarter 2017.

Accounting Standards Updates Not Yet Effective: On May 28, 2014,In March 2020, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,2020-04, “Reference Rate Reform (Topic 848)” which provides optional guidance for a limited period of time to ease the potential burden in accounting for reference rate reform on financial reporting. The provisions of this update are effective for all entities as of March 12, 2020 through December 31, 2022 and apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. We are evaluating the impact of the optional expedients in this update and their applicability to modifications of our existing credit facilities and hedging relationships that reference LIBOR.
(2) BUSINESS ACQUISITIONS
ECM Acquisition
On July 1, 2021, pursuant to a Unit Purchase Agreement, we acquired an 80% ownership interest in ECM Associated, LLC ("ECM”), based in Cheswick, Pennsylvania, for $141.3 million after net working capital changes and net of cash acquired. We have an exclusive option to purchase the remaining 20% ownership interest in ECM upon the occurrence of certain events or after a period of five years following transaction close, based on a fixed multiple of ECM’s average annual adjusted earnings before interest, taxes, depreciation and amortization. The noncontrolling interest holder also has an option to put the remaining 20% ownership interest to us on the same terms. We record the 20% remaining interest in temporary equity – redeemable noncontrolling interest in the consolidated balance sheets.
ECM, through its ECM Transport, LLC (“ECM Transport”) and Motor Carrier Service (“MCS”) subsidiaries, provides regional truckload carrier services in the Mid-Atlantic, Ohio, and Northeast regions of the U.S. and operates nearly 500 trucks and 2,000 trailers in its network of eight operational facilities and 18 drop yards. The primary reason for this acquisition was to expand our fleet size, operational facilities, geographic market presence, and short-haul expertise in a segment in which consumer demand and supply chain needs are growing.
We financed the cash transaction through a combination of cash on hand, existing credit facilities, and the addition of a $100.0 million unsecured fixed-rate term loan commitment with BMO Harris Bank N.A. on June 30, 2021. For more information regarding our debt, see Note 8 – Debt and Credit Facilities.
The results of operations for ECM are included in our consolidated financial statements beginning July 1, 2021. Revenues generated by ECM are reported in our Truckload Transportation Services (“TTS”) segment. We incurred transaction costs related to the acquisition, such as legal and professional fees, of $1.0 million for the year ended December 31, 2021, which is included in other operating expenses on the consolidated statements of income.
NEHDS Acquisition
On November 22, 2021, we acquired 100% of the equity interests in NEHDS Logistics, LLC (“NEHDS”), based in Monroe, Connecticut, for a cash purchase price of $63.1 million after including the impacts of contingent consideration, net working capital changes and cash acquired. We financed the transaction through a combination of cash on hand and existing credit facilities. NEHDS is a final mile residential delivery provider with access to a network of 400 final mile delivery trucks serving
37

customers primarily in the Northeast and Midwest U.S. markets. NEHDS delivers primarily big and bulky products (primarily furniture and appliances) using 2-person delivery teams performing residential and commercial deliveries through a network of 19 cross dock, warehouse, and customer facilities.
The results of operations for NEHDS are included in our consolidated financial statements beginning November 22, 2021. Revenues generated by NEHDS are reported in Final Mile within our Werner Logistics segment. We incurred transaction costs related to the acquisition, such as legal and professional fees, of $0.6 million for the year ended December 31, 2021, which is included in other operating expenses on the consolidated statements of income.
Purchase Price Allocations
We accounted for the purchases of ECM and NEHDS using the acquisition method of accounting under U.S. generally accepted accounting principles (GAAP). The purchase price of each acquisition has been allocated to the assets acquired and liabilities assumed using market data and valuation techniques. The purchase price allocation for ECM is considered final. The estimated fair values of the assets acquired and liabilities assumed are considered provisional for NEHDS, pending the completion of the valuation of acquired tangible assets, an independent valuation of certain acquired intangible assets, and the calculation of deferred taxes based upon the underlying tax basis of assets acquired and liabilities assumed. The determination of estimated fair values requires an entitymanagement to recognizemake significant estimates and assumptions. We believe that the information available provides a reasonable basis for estimating the values of assets acquired and liabilities assumed in the NEHDS acquisition; however, these provisional estimates may be adjusted upon the availability of new information regarding facts and circumstances which existed at the acquisition date, and such adjustments may impact future earnings. We expect to finalize the valuation of assets and liabilities for NEHDS as soon as practicable, but not later than one year from the acquisition date. Any adjustments to the initial estimates of the fair value of the acquired assets and liabilities assumed in the NEHDS acquisition will be recorded as adjustments to the respective assets and liabilities, with the residual amounts allocated to goodwill.
The purchase price allocations for ECM and NEHDS as of December 31, 2021 are summarized as follows (in thousands):

(3) The contingent consideration arrangement, also referred to as earnout, requires us to pay the former owners of NEHDS additional amounts in cash if certain levels of gross profit and revenues are earned during calendar year 2022. The potential undiscounted amount of revenueall future earnout payments that we could be required to make is between $0 and $4.0 million. The fair value of the contingent consideration arrangement of $2.5 million was estimated by management.

Goodwill and Intangible Assets
Goodwill associated with the ECM and NEHDS acquisitions was primarily attributable to acquiring and retaining each of the companies’ existing networks and the anticipated synergies from combining the operations of the Company and the acquired companies. The goodwill associated with the acquisitions above is expected to be deductible for income tax purposes.
We have allocated a total of $57.2 million of the purchase prices above to finite-lived intangible assets, consisting of customer relationships and trade names. The estimated fair values of the intangible assets were determined, with the assistance of an independent third-party valuation firm, using the multi-period excess earnings method for customer relationships and the relief-from-royalty method for trade names. All methods are forms of the income approach, which it expectsrequire a forecast of all the expected future cash flows.

Transportation Services
We generate nearly all of our revenues by transporting truckload freight shipments for our customers. Transportation services are carried out by our Truckload Transportation Services (“TTS”) segment and our Werner Logistics (“Logistics”) segment. The TTS segment utilizes company-owned and independent contractor trucks to deliver shipments, while the Logistics segment uses third-party capacity providers.
We generate revenues from billings for transportation services under contracts with customers, generally on a rate per mile or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The FASB has also issued additional guidance related to revenue recognition matters in subsequent ASUs, including a one-year deferralper shipment, based on origin and destination of the effective dateshipment. Our performance obligation arises when we receive a shipment order to transport a customer’s freight and is satisfied upon delivery of the new revenue standard. Asshipment. The transaction price may be defined in a result

transportation services agreement or negotiated with the customer prior to accepting the shipment order. A customer may submit several shipment orders for transportation services at various times throughout a service agreement term, but each shipment represents a distinct service that is a separately identified performance obligation. We often provide additional or ancillary services as part of the deferral,shipment (such as loading/unloading and stops in transit) which are not distinct or are not material in the new standard is effectivecontext of the contract; therefore, the revenues for us beginning January 1, 2018. Priorthese services are recognized with the freight transaction price. The average transit time to adopting, we recognize revenue and related direct costs when thecomplete a shipment is delivered. Effective January 1, 2018,approximately 3 days. Invoices for transportation services are typically generated soon after shipment delivery and, while payment terms and conditions vary by customer, are generally due within 30 days after the new standard requires us to recognize revenueinvoice date.
The consolidated statements of income reflect recognition of transportation revenues (including fuel surcharge revenues) and related direct costs over time as the shipment is being delivered. The standard permitsWe use distance shipped (for the useTTS segment) and transit time (for the Logistics segment) to measure progress and the amount of eitherrevenues recognized over time, as the full retrospectivecustomer simultaneously receives and consumes the benefit. Determining a measure of progress requires us to make judgments that affect the timing of revenues recognized. We have determined that the methods described provide a faithful depiction of the transfer of services to the customer.
For shipments where a third-party capacity provider (including independent contractors under contract with us) is utilized to provide some or modified retrospective (cumulative effect) transition method.all of the service, we evaluate whether we are the principal (i.e., report revenues on a gross basis) or agent (i.e., report revenues on a net basis). Generally, we report such revenues on a gross basis, that is, we recognize both revenues for the service we bill to the customer and rent and purchased transportation expense for transportation costs we pay to the third-party provider. Where we are the principal, we control the transportation service before it is provided to our customers, which is supported by us being primarily responsible for fulfilling the shipment obligation to the customer and having a level of discretion in establishing pricing with the customer.
During 2021, 2020, and 2019, revenues recognized from performance obligations related to prior periods (for example, due to changes in transaction price) were not material.
Other Revenues
Other revenues include revenues from our driver training schools, transportation-related activities such as third-party equipment maintenance and equipment leasing, and other business activities. These revenues are generally recognized over time and accounted for 2% of our total revenues in both 2021 and 2020, and 3% of our total revenues in 2019. Revenues from our driver training schools require us to make judgments regarding price concessions in determining the amount of revenues to recognize.
Contract Balances and Accounts Receivable
A receivable is an unconditional right to consideration and is recognized when shipments have been completed and the related performance obligation has been fully satisfied. At December 31, 2021 and 2020, the accounts receivable, trade, net, balance was $460.5 million and $341.1 million, respectively. Contract assets represent a conditional right to consideration in exchange for goods or services and are transferred to receivables when the rights become unconditional. At December 31, 2021 and 2020, the balance of contract assets was $9.0 million and $6.9 million, respectively. We will adopthave recognized contract assets within the standard usingother current assets financial statement caption on the modified retrospective transition method. Based on our evaluation, the adoption of this standard will not have a material effect on our consolidated financial statements, although additional disclosuresbalance sheets. These contract assets are considered current assets as they will be required.settled in less than 12 months.
In February 2016,Contract liabilities represent advance consideration received from customers and are recognized as revenues over time as the FASB issued ASU No. 2016-02, “Leases,”related performance obligation is satisfied. At December 31, 2021 and 2020, the balance of contract liabilities was $1.2 million and $1.5 million, respectively. The amount of revenues recognized in 2021 that was included in the December 31, 2020 contract liability balance was $1.5 million. We have recognized contract liabilities within the accounts payable and other current liabilities financial statement captions on the consolidated balance sheets. These contract liabilities are considered current liabilities as they will be settled in less than 12 months.
Performance Obligations
We have elected to increase transparencyapply the practical expedient in Accounting Standards Codification (“ASC”) Topic 606, Revenue From Contracts With Customers, to not disclose the value of remaining performance obligations for contracts with an original expected length of one year or less. Remaining performance obligations represent the transaction price allocated to future reporting periods for freight shipments started but not completed at the reporting date that we expect to recognize as revenue in the period subsequent to the reporting date; transit times generally average approximately 3 days.

(5) LEASES
We have entered into operating leases primarily for real estate. The leases have terms which range from 1 year to 18 years, and some include options to renew. Renewal terms are included in the lease term when it is reasonably certain that we will exercise the option to renew.
Operating leases are included in other non-current assets, other current liabilities and leaseother long-term liabilities on the consolidated balance sheetsheets.

The provisionsliabilities are recognized based on the present value of this update are effectivefuture minimum lease payments over the lease term at commencement date, using our incremental borrowing rate because the rate implicit in each lease is not readily determinable. We have certain contracts for fiscal years beginning after December 15, 2018. We are evaluatingreal estate that may contain lease and non-lease components which we have elected to treat as a single lease component. Lease expense for operating leases is recognized on a straight-line basis over the effect that ASU No. 2016-02 will have on our consolidated financial position, results of operations and cash flows.
In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments,” which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The provisions of this update are effective for fiscal years beginning after December 15, 2017. Based on our evaluation, the adoption of this standard will not have a material effect on our consolidated statement of cash flows.
In November 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash,” which requires an entity to include in its cash and cash-equivalent balanceslease term. Variable lease expense is recognized in the statement of cash flowsperiod in which the obligation for those amounts that are deemed to be restricted cashpayments is incurred. Lease expense is reported in rent and restricted cash equivalents. The provisions of this update are effective for fiscal years beginning after December 15, 2017, and retrospective adoption is required.

An initial right-of-use asset of $8.7 million was recognized as a non-cash asset addition with the adoption of the new lease accounting standard on January 1, 2019. During the years ended December 31, 2021, 2020, and 2019, additional right-of-use assets of $8.2 million, $2.8 million, and $6.1 million, respectively, were recognized as non-cash asset additions that resulted from new operating lease liabilities, and we acquired right-of-use assets of $15.6 million as a result of our like-kind exchange accountbusiness acquisitions during the year ended December 31, 2021.

In May 2017, the FASB issued ASU No. 2017-09, “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting,” which provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The provisions of this update are effective for fiscal years beginning after December 15, 2017, and would be applied prospectively to an award modified on or after the adoption date, if any such modification were to occur.
In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities,” with the objective of improving the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. The provisions of this update are effective for fiscal years beginning after December 15, 2018. We are evaluating the effect that ASU No. 2017-12 will have on our financial position, results of operations and cash flows.

(6) FAIR VALUE
Fair Value Measurement — Definition and Hierarchy
ASC 820-10, Fair Value Measurement, defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date.
ASC 820-10 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability, developed based on market data obtained from sources independent of the Company. Unobservable inputs reflect our own assumptions about the assumptions market participants would use in pricing the asset or liability, developed based on the best information available in the circumstances.
The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels, as follows:
Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access.
Level 2 — Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Such inputs include quoted prices in markets that are not active, quoted prices for similar assets and liabilities in active and inactive markets, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable market data by correlation or other means.
Level 3 — Unobservable inputs for the asset or liability, where there is little, if any, observable market activity or data for the asset or liability.
In general, and where applicable, we use quoted prices in active markets for identical assets or liabilities to determine fair value. This pricing methodology applies to our Level 1 assets and liabilities. If quoted prices in active markets for identical assets and liabilities are not available to determine fair value, then we use quoted prices for similar assets and liabilities or inputs other than the quoted prices that are observable, either directly or indirectly. This pricing methodology would apply to Level 2 assets and liabilities.

Our ownership interest in Mastery Logistics Systems, Inc. (“MLSI”) does not have a readily determinable fair value and is accounted for using the measurement alternative in ASC 321, Investments - Equity Securities. For additional information regarding the valuation of our investment in MLSI, see Note 7 – Investments.
Fair Value of Financial Instruments Not Recorded at Fair Value
Cash, accounts receivable trade, and accounts payable are short-term in nature and accordingly are carried at amounts that approximate fair value. These financial instruments are recorded at or near their respective transaction prices and historically have been settled or converted to cash at approximately that value (categorized as Level 2 of the fair value hierarchy).
The carrying amounts of our long-term debt approximate fair value due to the duration of our credit arrangements and the variable interest rates (categorized as Level 2 of the fair value hierarchy).
(7) INVESTMENTS
Equity Investments without Readily Determinable Fair Values
In 2020, we entered into a strategic partnership with MLSI, a transportation management systems company. We are collaborating with MLSI to develop a cloud-based transportation management system using MLSI's SaaS technology which we have agreed to license. In both November 2020 and September 2021, we paid MLSI $5.0 million for shares of its preferred stock. As of December 31, 2017,2021, our ownership percentage in MLSI was approximately 9.8%. This investment is being accounted for under ASC 321 using the measurement alternative, and is recorded in other noncurrent assets on the consolidated balance sheets. We record changes in the value of this investment, based on events that occur that would indicate the value of our investment in MLSI has changed, in other expense (income) on the consolidated statements of income. During 2021, an investment by a third-party resulted in the remeasurement of our investment in MLSI and we recognized a $28.2 million unrealized gain on our investment based upon the price paid by the third party. As of December 31, 2021 and 2020, the value of our investment was $38.2 million and $5.0 million, respectively.
Equity Investments with Readily Determinable Fair Values
During 2021, we acquired strategic minority equity investments in autonomous technology companies, which are being accounted for under ASC 321 and are recorded in other noncurrent assets on the consolidated balance sheets. We record changes in the value of these investments, based on the share prices reported by Nasdaq, in other expense (income) on the consolidated statements of income. We recognized a $12.1 million net unrealized gain on these investments for the year ended December 31, 2021. For additional information regarding the fair value of these equity investments, see Note 6 – Fair Value.

(4)(10) INCOME TAXES
The Tax Cuts and Jobs Act of 2017 (the “Tax Act”) was enacted on December 22, 2017, and lowered the federal corporate income tax rate to 21% from 35% effective January 1, 2018. In accounting for income taxes, deferred income tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using the enacted tax rates that are expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. As a result of the reduction of the federal corporate income tax rate under the Tax Act, the Company revalued its ending net deferred income tax liabilities at December 31, 2017 and recognized a provisional $110.5 million income tax benefit.
The SEC staff issued Staff Accounting Bulletin No. 118 to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed in reasonable detail to complete the accounting for certain income tax effects of the Tax Act. The Company has recognized the provisional tax impact related to the revaluation of deferred income tax assets and liabilities and included the amount in its consolidated financial statements for the year ended December 31, 2017.  The ultimate impact may differ from the provisional amount due to, among other things, additional analysis, changes in interpretations and assumptions the Company has made, and additional regulatory guidance that may be issued.  The accounting is expected to be completed when the Company’s 2017 income tax returns are filed later in 2018.

Deferred income tax assets are more likely than not to be realized as a result of future taxable income and reversal of deferred income tax liabilities.
We recognized a $1.6 million decrease$49 thousand increase in the net liability for unrecognized tax benefits for the year ended December 31, 2017, including the impact of the federal tax rate change,2021, and a $1.1 million$141 thousand decrease for the year ended December 31, 2016.2020. We accrued interest expense of $0.2$0.1 million during 20172021 and $0.2 million during 2016,2020, excluding from both years the reversal of accrued interest related to the adjustment of uncertain tax positions. If recognized, $2.3$1.9 million and $1.8 million of unrecognized tax benefits as of December 31, 20172021 and $3.9 million as of December 31, 20162020, respectively, would impact our effective tax rate. Interest of $0.4 million as of December 31, 20172021 and $1.1 million as of December 31, 20162020 has been reflected as a component of the total liability. We expect no other significant increases or decreases for uncertain tax positions during the next twelve12 months.

(5)(11) EQUITY COMPENSATION AND EMPLOYEE BENEFIT PLANS
Equity Compensation Plan
The Werner Enterprises, Inc. Amended and Restated Equity Plan (the “Equity Plan”), approved by the Company’s shareholders in 2013, provides for grants to employees and non-employee directors of the Company in the form of nonqualified stock options, restricted stock and units (“restricted awards”), performance awards, and stock appreciation rights. The Board of Directors or the Compensation Committee of our Board of Directors determines the terms of each award, including the type, recipients, number of shares subject to and vesting conditions of each award. No awards of stock appreciation rights have been issued under the Equity Plan to date. The maximum number of shares of common stock that may be awarded under the Equity Plan is 20,000,000 shares. The maximum aggregate number of shares that may be awarded to any one person in any one calendar year under the Equity Plan is 500,000.500,000. As of December 31, 2017,2021, there were 7,349,8796,508,744 shares available for granting additional awards.

Equity compensation expense is included in salaries, wages and benefits within the Consolidated Statementsconsolidated statements of Income.income. As of December 31, 2017,2021, the total unrecognized compensation cost related to non-vested equity compensation awards was approximately $6.6$11.8 million and is expected to be recognized over a weighted average period of 2.11.6 years.

We do not have a formal policy for issuing shares upon an exercise of stock options or vesting of restricted and performance awards. Such shares are generally issued from treasury stock. From time to time, we repurchase shares of our common stock, the timing and amount of which depends on market and other factors. Historically, the shares acquired from such repurchases have provided us with sufficient quantities of stock to issue for equity compensation. Based on current treasury stock levels, we do not expect to repurchase additional shares specifically for equity compensation during 2018.2022.
Stock Options
Stock options are granted at prices equal to the market value of the common stock on the date the option award is granted. Option awards currently outstanding became exercisable in installments from 24 to 72 months after the date of grant. The options are exercisable over a period not to exceed ten years and one day from the date of grant.

Restricted Awards
Restricted stock entitles the holder to shares of common stock when the award vests. Restricted stock units entitle the holder to a combination of cash or stock equal to the value of common stock when the unit vests. The value of these shares may fluctuate according to market conditions and other factors. Restricted awards currently outstanding vest over periods ranging from 12 to 60 months from the grant date of the award. The restricted awards do not confer any voting or dividend rights to recipients until such shares vest and do not have any post-vesting sales restrictions.

We estimate the fair value of restricted awards based upon the market price of the underlying common stock on the date of grant, reduced by the present value of estimated future dividends because the awards are not entitled to receive dividends prior to vesting. Our estimate of future dividends is based on the most recent quarterly dividend rate at the time of grant, adjusted for any known future changes in the dividend rate. Cash settled restricted stock units are recorded as a liability within the Consolidated Balance Sheetsconsolidated balance sheets and are adjusted to fair value each reporting period.
The total fair value of previously granted restricted awards vested during the years ended December 31, 2017, 2016,2021, 2020, and 20152019 was $4.4$6.8 million,, $4.3 $5.4 million, and $4.5$4.0 million, respectively. We withheld shares based on the closing stock price on the vesting date to settle the employees’ minimum statutory obligation for the applicable income and other employment taxes. Total cash remitted for the employees’ tax obligations to the relevant taxing authorities is reflected as a financing activity within the Consolidated Statements of Cash Flows, and theThe shares withheld to satisfy the minimum tax withholding obligations were recorded as treasury stock.
Performance Awards
Performance awards entitle the recipient to shares of common stock upon attainment of performance objectives as pre-established by the Compensation Committee. If the performance objectives are achieved, performance awards currently outstanding vest, subject to continued employment, over periods ranging from 12 to 6036 months fromafter the grant date of the award. The performance awards do not confer any voting or dividend rights to recipients until such shares vest and do not have any post-vesting sales restrictions.

We estimate the fair value of performance awards based upon the market price of the underlying common stock on the date of grant, reduced by the present value of estimated future dividends because the awards are not entitled to receive dividends prior to

vesting. Our estimate of future dividends is based on the most recent quarterly dividend rate at the time of grant, adjusted for any known future changes in the dividend rate.
The vesting date fair value of the performance awards that vested during the years ended December 31, 2017, 20162021, 2020 and 20152019 was $1.0$4.1 million, $1.6$5.8 million and $1.1$1.2 million, respectively. We withheld shares based on the closing stock price on the vesting date to settle the employees’ minimum statutory obligation for the applicable income and other employment taxes. Total cash remitted for employees’ tax obligations to the relevant taxing authorities is reflected as a financing activity within the Consolidated Statements of Cash Flows, and theThe shares withheld to satisfy the minimum tax withholding obligations arewere recorded as treasury stock.
Employee Stock Purchase Plan
Employee associates that meet certain eligibility requirements may participate in our Employee Stock Purchase Plan (the “Purchase Plan”). Eligible participants designate the amount of regular payroll deductions and/or a single annual payment (each subject to a yearly maximum amount) that is used to purchase shares of our common stock on the over-the-counter market. The maximum annual contribution amount is currently $20,000.$20,000. These purchases are subject to the terms of the Purchase Plan. We contribute an amount equal to 15% of each participant’s contributions under the Purchase Plan. Interest accrues on Purchase Plan contributions at a rate of 5.25% until the purchase is made. We pay the broker’strading commissions and administrative charges related to purchases of common stock under the Purchase Plan. Our contributions for the Purchase Plan were as follows (in thousands):

Nonqualified Deferred Compensation Plan
The Executive Nonqualified Excess Plan (the “Excess Plan”) is our nonqualified deferred compensation plan for the benefit of eligible key managerial associates whose 401(k) Plan contributions are limited because of IRS regulations affecting highly compensated associates. Under the terms of the Excess Plan, participants may elect to defer compensation on a pre-tax basis within annual dollar limits we establish. At December 31, 2017,2021, there were 4145 participants in the Excess Plan. Although our current intention is not to do so, we may also make matching credits and/or profit sharing credits to participants’ accounts as we so determine each year. Each participant is fully vested in all deferred compensation and earnings; however, these amounts are subject to general creditor claims until distributed to the participant. Under current federal tax law, we are not allowed a current income tax deduction for the compensation deferred by participants, but we are allowed a tax deduction when a distribution payment is made to a participant from the Excess Plan. The accumulated benefit obligation is included in other long-term liabilities in the Consolidated Balance Sheets.consolidated balance sheets.

(6)(12) COMMITMENTS AND CONTINGENCIES
We have committed to property and equipment purchases of approximately $185.3$163.2 million at December 31, 2017.2021.
We are involved in certain claims and pending litigation, including those described herein, arising in the ordinary course of business. The majority of these claims relate to bodily injury, property damage, cargo and workers’ compensation incurred in the transportation of freight, as well as certain class action litigation related to personnel and employmentsemployment matters. We accrue for the uninsured portion of contingent

losses from these and other pending claims when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Based on the knowledge of the facts, management believes the resolution of claims and pending litigation, taking into account existing reserves, will not have a material adverse effect on our consolidated financial statements. Moreover, the results of complex legal proceedings are difficult to predict, and our view of these matters may change in the future as the litigation and related events unfold.
On May 17, 2018, in Harris County District Court in Houston, Texas, a jury rendered an adverse verdict against Werner Enterprises, Inc. (the “Company”) in a lawsuit arising from a December 30, 2014 accident between a Werner tractor-trailer and a passenger vehicle. On July 30, 2018, the court entered a final judgment against Werner for $92.0 million, including pre-judgment interest.
The Company has premium-based liability insurance to cover the potential outcome from this jury verdict. Under the Company’s insurance policies in effect on the date of this accident, the Company’s maximum liability for this accident is $10.0 million (plus pre-judgment and post-judgment interest) with premium-based coverage that exceeds the jury verdict amount. As a result of this jury verdict, the Company had recorded a liability of $28.8 million and $23.6 million as of December 31, 2021 and 2020, respectively. Under the terms of the Company’s insurance policies, the Company is the primary obligor of the verdict, and as such, the Company has also recorded a $79.2 million receivable from its third-party insurance providers in other non-current assets and a corresponding liability of the same amount in the long-term portion of insurance and claims accruals in the consolidated balance sheets as of December 31, 2021 and 2020.
The Company is pursuing an appeal of this verdict. No assurances can be given regarding the outcome of any such appeal.
We arehave been involved in class action litigation in the U.S. District Court for the District of Nebraska, in which the plaintiffs allege that we owe drivers for unpaid wages under the Fair Labor Standards Act (FLSA)(“FLSA”) and the Nebraska Wage Payment and Collection Act and that we failed to pay minimum wage per hour for drivers in our student driver training program,Career Track Program, related to short break time and sleeper berth time. The period covered by this class action suit is August 2008 through March 2014. The case was tried to a jury in May 2017, resulting in a verdict of $0.8 million in plaintiffs’ favor on the short break matter and a verdict in our favor on the sleeper berth matter. As a result of various post-trial motions, the court has awarded $0.5 million to the plaintiffs for attorney fees and costs. Plaintiffs appealed the post-verdict amounts awarded by the trial court for fees, costs and liquidated damages, and the Company filed a cross appeal on the verdict that was in plaintiffs’ favor. The United States Court of Appeals for the Eighth Circuit denied Plaintiffs’ appeal and granted Werner’s appeal, vacating the judgment in favor of the plaintiffs. The appellate court sent the case back to the trial court for proceedings consistent with the appellate court’s opinion. On June 22, 2020, the trial court denied Plaintiffs’ request for a new trial and entered judgment in favor of the Company, dismissing the case with prejudice. On July 21, 2020, Plaintiffs’ counsel filed a notice of appeal of that dismissal, and that appeal remains pending. As of December 31, 2017,2021, we had accruedhave an accrual for the jury’s award, attorney fees and costs in the short break matter and had not accrued for the sleeper berth matter.
We are also involved in certain class action litigation in which the plaintiffs allege claims for failure to provide meal and rest breaks, unpaid wages, unauthorized deductions and other items. Based on the knowledge of the facts, management does not currently believe the outcome of these class actions is likely to have a material adverse effect on our financial position or results of operations. However, the final disposition of these matters and the impact of such final dispositions cannot be determined at this time.

(8)(14) SEGMENT INFORMATION
We have two reportable segments – Truckload Transportation Services (“Truckload”) and Werner Logistics.
The TruckloadTTS segment consists of threetwo operating units, One-Way Truckload, Dedicated and Temperature Controlled.One-Way Truckload. These units are aggregated because they have similar economic characteristics and meet the other aggregation criteria described in the accounting guidance for segment reporting. Dedicated provides truckload services dedicated to a specific customer, generally for a retail distribution center or manufacturing facility, utilizing either dry van or specialized trailers. One-Way Truckload is comprised of the following operating fleets: (i) the medium-to-long-haul van (“Van”) fleet transports a variety of consumer nondurable products and other commodities in truckload quantities over irregular routes using dry van trailers;trailers, including Mexico cross-border routes; (ii) the expedited (“Expedited”) fleet provides time-sensitive truckload services utilizing driver teams; and (iii) the regional short-haul (“Regional”) fleet, including ECM, provides comparable truckload van service within geographic regions across the United States. Dedicated provides truckload services dedicated to a specific customer, generally for a retail distribution center or manufacturing facility, utilizing either dry van or specialized trailers.States; and (iv) the Temperature Controlled fleet provides truckload services for temperature sensitive products over irregular routes utilizing temperature-controlled trailers. (We previously utilized the name “Specialized Services” to encompass the operations of both Dedicated and Temperature Controlled.) Revenues for the TruckloadTTS segment include a small amount of non-trucking revenues which consist primarily of the intra-Mexico portion of cross-border shipments delivered to or from Mexico where we utilize a third-party capacity provider.
The Werner Logistics segment generates the majority of our non-trucking revenues through fivethree operating units that provide non-trucking services to our customers. These fivethree Werner Logistics operating units are as follows: (i) truck brokerage (“Brokerage”)Truckload Logistics, which uses contracted carriers to complete customer shipments; (ii)shipments for brokerage customers and freight management (“Freight Management”) offerscustomers for which we offer a full range of single-source logistics management services and solutions; (iii)(ii) the intermodal (“Intermodal”) unit offers rail transportation through alliances with rail and drayage providers as an alternative to truck transportation; (iv) Werner Global Logistics international (“WGL”) provides complete management of global shipments from origin to destination using a combination of air, ocean, truck and rail transportation modes; and (v)(iii) Werner Final Mile (“Final Mile”), including NEHDS, offers homeresidential and businesscommercial deliveries of large or heavy items using two associatesthird-party agents, independent contractors, and Company employees with two-person delivery teams operating a liftgate straight truck. In first quarter 2021, we completed the previously-announced sale of the Werner Global Logistics (“WGL”) freight forwarding services for international ocean and air shipments to Scan Global Logistics Group, and we realized a $1.0 million gain when the transaction closed on February 26, 2021. Werner Logistics will continue to provide North American truck brokerage, freight management, intermodal and final mile services.
We generate other revenues from our driver training schools, transportation-related activities such as third-party equipment maintenance and equipment leasing, and other business activities. None of these operations meets the quantitative reporting thresholds. As a result, these operations are grouped in “Other” in the tables below. “Corporate” includes revenues and expenses that are incidental to our activities and are not attributable to any of our operating segments, including gains and losses on sales of assets not attributable to our operating segments.
We do not prepare separate balance sheets by segment and, as a result, assets

are not separately identifiable by segment. Based on our operations, certain revenue-generating assets (primarily tractors and trailers) are interchangeable between segments. Depreciation for these interchangeable assets is allocated to segments based on the actual number of units utilized by the segment during the period. Other depreciation and amortization is allocated to segments based on specific identification or as a percentage of a metric such as average number of tractors. Inter-segment eliminations in the table below represent transactions between reporting segments that are eliminated in consolidation.

ITEM 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE
No disclosure under this item was required within the two most recent fiscal years ended December 31, 2017,2021, or any subsequent period, involving a change of accountants or disagreements on accounting and financial disclosure.


ITEM 9A.CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Exchange Act Rule 15d-15(e). Our disclosure controls and procedures are designed to provide reasonable assurance of achieving the desired control objectives. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective at a reasonable assurance level in enabling us to record, process, summarize and report information required to be included in our periodic filings with the SEC within the required time period and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.
We have confidence in our internal controls and procedures. Nevertheless, our management, including the Chief Executive Officer and Chief Financial Officer, does not expect that the internal controls or disclosure procedures and controls will prevent all errors or intentional fraud. An internal control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of such internal controls are met. Further, the design of an internal control system must reflect that resource constraints exist, and the benefits of controls must be evaluated relative to their costs. Because of the inherent limitations in all internal control systems, no evaluation of controls can provide absolute assurance that all control issues, misstatements and instances of fraud, if any, have been prevented or detected.
Management’s Report on Internal Control over Financial Reporting
Management is responsible for establishing and maintaining adequate internal control over our financial reporting. Internal control over financial reporting is a process designed to provide reasonable assurance to our management and Board of Directors regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. Internal control over financial reporting includes (i) maintaining records that in reasonable detail accurately and fairly reflect our transactions; (ii) providing reasonable assurance that transactions are recorded as necessary for preparation of our financial statements; (iii) providing reasonable assurance that receipts and expenditures of company assets are made in accordance with management authorization; and (iv) providing reasonable assurance that unauthorized

acquisition, use or disposition of company assets that could have a material effect on our financial statements would be prevented or detected on a timely basis.
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 (i) changes in conditions may occur or (ii) the degree of compliance with the policies or procedures may deteriorate.
Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2017.2021. This assessment is based on the criteria for effective internal control described in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on its assessment, management concluded that our internal control over financial reporting was effective as of December 31, 2017.2021.
Management has engaged KPMG LLP (“KPMG”), the independent registered public accounting firm that audited the consolidated financial statements included in this Form 10-K, to attest to and report on the effectiveness of our internal control over financial reporting. KPMG’s report is included herein.

Opinion on Internal Control Over Financial Reporting
We have audited Werner Enterprises, Inc. and subsidiaries’ (the Company) internal control over financial reporting as of December 31, 2017,2021, based on criteria established inInternal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017,2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
We also have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 20172021 and 2016,2020, the related consolidated statements of income, comprehensive income, stockholders’ equity and temporary equity - redeemable noncontrolling interest, and cash flows for each of the years in the three-year period ended December 31, 2017,2021, and the related notes and financial statement schedule II listed in the Index in Item 15(a)(2) (collectively, the consolidated financial statements), and our report dated February 27, 2018,28, 2022 expressed an unqualified opinion on those consolidated financial statements.
Basis for Opinion
The Company’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 InternalControl over Financial Reporting.Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. 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 of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
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.
