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 Value Added Services (“VAS”) division. 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 serves as our Chairman and Chief Executive Officer. 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 2015, we had a fleet of 7,450 trucks, of which 6,635 were company-operated and 815 were owned and operated by independent contractors. Our VAS division operated an additional 62 intermodal drayage trucks at the end of 2015.

We have two reportable segments – Truckload Transportation Services (“Truckload”) and VAS. You can find financial information regarding these segments and the geographic areas in which we conduct business in the Notes to Consolidated Financial Statements under Item 8 of this Form 10-K.

Our Truckload segment is comprised of the One-Way Truckload and Specialized Services units. 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; (ii) the expedited (“Expedited”) fleet provides time-sensitive truckload services utilizing driver teams; and (iii) the regional short-haul (“Regional”) fleet provides comparable truckload van service within geographic regions across the United States. Specialized Services provides truckload services dedicated to a specific customer, generally for a retail distribution center or manufacturing facility, including services for products requiring specialized trailers such as flatbed or temperature-controlled trailers. Our Truckload 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, grocery 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 VAS segment is a non-asset-based transportation and logistics provider. VAS is comprised of the following four operating units that provide non-trucking services to our customers: (i) truck brokerage (“Brokerage”) uses contracted carriers to complete customer shipments; (ii) freight management (“Freight Management”) offers a full range of single-source logistics management services and solutions; (iii) 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. Our Brokerage unit had transportation services contracts with approximately 12,920 carriers as of December 31, 2015.

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 Truckload segment provides specialized services to customers based on (i) each customer’s trailer needs (such as van, flatbed 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 2015, trucking revenues (net of fuel

1

surcharge) and trucking fuel surcharge revenues accounted for 78% of total operating revenues, and non-trucking and other operating revenues (primarily VAS revenues) accounted for 22% of total operating revenues. Our VAS 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. VAS services include (i) truck brokerage, (ii) freight management, (iii) intermodal transport and (iv) international. The VAS 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 VAS international services are provided throughout North America and Asia with additional coverage throughout Australia, Europe, South America and Africa. VAS 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 Truckload and VAS, for the last three years under Item 7 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. During 2015, our largest 5, 10, 25 and 50 customers comprised 27%, 45%, 63% and 76% of our revenues, respectively. No single customer generated more than 10% of our revenues in 2015. The industry groups of our top 50 customers are 44% retail and consumer products, 28% grocery products, 13% manufacturing/industrial and 15% 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 our Specialized Services customer contracts are one to three years in length and may be terminated by either party upon 30 to 90 days’ notice following the expiration of the contract’s first year, and we review rates in these contracts annually.

Virtually 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 15 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 system-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.

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.

Employee Associates and Independent Contractors

As of December 31, 2015, we employed 9,192 drivers; 664 mechanics and maintenance associates for the trucking operation; 1,306 office associates for the trucking operation; and 1,163 associates for VAS, international and other non-trucking operations. We also had 815 independent contractors who provide both a tractor and a driver or drivers. None of our U.S., Canadian or Chinese associates are represented by a collective bargaining unit, and we consider relations with our associates to be good.

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).

2

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 very challenging in 2015, 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, a gradually declining national unemployment rate, aging truck driver demographics and increased truck safety regulations are tightening driver supply. We believe our strong mileage utilization, financial strength and safety record are attractive to drivers when compared to many other carriers. Additionally, we believe our large percentage of driving jobs in shorter-haul operations (such as Dedicated and Regional) that allow drivers to return home more often is attractive to drivers.

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, hold a commercial driver’s license (“CDL”) and are further trained by Werner-certified trainer drivers prior to that driver becoming a solo driver with their own truck. As mentioned above, the recruiting environment for recent driver training school graduates remained challenging in 2015. The availability of these drivers has been negatively impacted by the decreased availability of student loan financing for driver training schools. We own two driver training schools that operate a total of 15 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 drivers and recent driver training school graduates may increase and could become more challenging in 2016. 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.

We also recognize that independent contractors complement our company-employed drivers. 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, 2015, we operated 6,635 company tractors and 815 tractors owned by independent contractors in our Truckload segment. Our VAS segment operated an additional 62 company tractors at the end of 2015. The company tractors were manufactured by Freightliner (a Daimler company), Peterbilt and Kenworth (both divisions of PACCAR) and Volvo. 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, and we have them set to not exceed 65 miles per hour.

The average age of our company truck fleet was 1.9 years at December 31, 2015, compared to 2.2 years at December 31, 2014. We increased our capital expenditures in 2015 to lower the average age of our truck fleet, and we currently expect to reduce our average truck age to approximately 1.5 years during 2016. As of December 31, 2015, nearly all of our company tractors had engines that comply with the U.S. Environmental Protection Agency (“EPA”) engine emissions standards that became effective for newly manufactured engines beginning in January 2010. All of our trucks are equipped with satellite tracking devices. Most of our new trucks purchased in 2015 have collision mitigation safety systems and a majority of new trucks purchased in 2015 have automatic manual transmissions.

We operated 24,090 company-owned trailers at December 31, 2015. This total is comprised of 22,560 dry vans; 184 flatbeds; 1,308 temperature-controlled trailers; and 38 specialized trailers. Most of our trailers were manufactured by Wabash National Corporation. As of December 31, 2015, nearly all of our dry van trailer fleet consisted of 53-foot composite (DuraPlate^®) trailers. We also provide other trailer lengths, such as 48-foot and 57-foot trailers, to meet the specialized needs of certain customers. Approximately one third of our trailer fleet has satellite tracking; this is expected to grow to two thirds of our trailer fleet by the end of 2016.

3

Our wholly-owned subsidiary, Fleet Truck Sales, sells our used trucks and trailers. Fleet Truck Sales has been in business since 1992 and operates in six locations. We may also trade used trucks to original equipment manufacturers when purchasing new trucks.

Fuel

In 2015, we purchased approximately 98% of our fuel from a predetermined network of fuel stops throughout the United States. Of this 98%, approximately 96% was purchased from three large fuel stop vendors. We negotiate discounted pricing based on historical purchase volumes with these fuel stop vendors. Bulk fueling facilities are maintained at seven of our terminals and one dedicated customer location.

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, 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, 2015, we had no derivative financial instruments to reduce our exposure to fuel price fluctuations.

We maintain aboveground and underground fuel storage tanks at many 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.

Regulations

We are a motor carrier regulated by DOT in the United States and similar governmental transportation agencies in foreign countries in which we operate. DOT generally governs matters such as safety requirements, registration to engage in motor carrier operations, drivers’ hours of service and certain mergers, consolidations and acquisitions. We currently have, and have always maintained, a satisfactory DOT safety rating, which is the highest available rating, and we continually take efforts to maintain our satisfactory rating. A conditional or unsatisfactory DOT safety rating could adversely affect us because some of our customer contracts require a satisfactory rating. Equipment weight and dimensions are also subject to federal, state and international regulations with which we are required to comply.

The Federal Motor Carrier Safety Administration's (“FMCSA”) Compliance, Safety, Accountability, (“CSA”) safety initiative monitors the safety performance of both individual drivers and carriers. In December 2010, FMCSA made public on its website the Safety Measurement System (“SMS”), which includes monthly reports of specific safety rating measurement and percentile ranking scores for over 500,000 trucking companies. Through the SMS, the public could access carrier scores and data (including a carrier’s roadside safety inspection, out-of-service and moving violation histories) for five Behavior Analysis and Safety Improvement Categories (“BASICs”). On December 3, 2015, Congress passed a multi-year surface transportation reauthorization, the Fixing America's Surface Transportation (“FAST”) Act. Within the bill was a provision instructing FMCSA to commission a Transportation Research Board study of the accuracy of CSA SMS in identifying high risk carriers and predicting future crash risk and severity. FMCSA must submit the study to Congress and issue a corrective action plan to address the deficiencies identified in the study. Beginning the day after enactment of the FAST Act, information regarding carrier alerts or percentile ranks (i.e., scores) was removed from public view until FMCSA completes the corrective action plan. We will continue to monitor any CSA developments and continue our CSA compliance efforts.

On January 15, 2016, FMCSA released a proposal to change the method for assigning motor carriers' safety fitness determination (“SFD”). The proposed methodology would determine when a carrier is not fit to operate commercial motor vehicles in or affecting interstate commerce based on (i) the carrier's performance in relation to a fixed failure threshold established in the rule for five CSA categories; (ii) an investigation; or (iii) a combination of on-road safety data and investigation information. Currently, the assignment of an SFD follows the completion of a labor-intensive compliance review conducted at the carrier's place of business. These audits are primarily an assessment of paper records instead of on-road safety performance. The proposed SFD rule would replace the current three-tier federal rating system which assigns a rating of either “satisfactory”,“conditional”, or “unsatisfactory” to federally regulated commercial motor carriers (in place since 1982) with a single determination of “unfit,” which would require the carrier to either improve its operations or cease operations.

All truckload carriers are subject to the hours of service (“HOS”) regulations issued by FMCSA. In December 2011, FMCSA adopted and issued a final rule that amended the driver HOS regulations, which became effective July 1, 2013. The rule includes provisions which affect restart periods, rest breaks, on-duty time and penalties for violations. We modified and tested our electronic HOS system and began dispatching drivers under the revised HOS rules effective July 1, 2013. The Company believes these HOS

4

changes negatively impacted miles per truck by two to three percent. We have taken steps to minimize the financial impact of the HOS changes. However, government restrictions of available driving hours will continue to negatively impact the productivity of some drivers and some fleets within our company. On August 2, 2013, the U.S. Court of Appeals for the D.C. Circuit issued its decision related to petitions of the rule changes by the trucking industry association and consumer advocate groups. The court generally affirmed FMCSA's final rule and vacated only the application of the 30-minute rest break to short-haul drivers as defined in 49 CFR 395.1(e). On December 13, 2014, Congress passed the Consolidated and Further Continuing Appropriations Act of 2015 which for one year temporarily suspended the requirement that all qualifying restarts contain two consecutive periods of time between 1:00 a.m. and 5:00 a.m. and that it can only be used once every 168 hours (or seven days). In addition, FMCSA was required to study the safety impact caused by the restart rule which became effective on July 1, 2013. The restart rule reverted back to the simple 34-hour restart in effect from 2003 to June 30, 2013. We believe this has reduced the negative impact of the July 1, 2013 HOS changes during the one year suspension period. On December 18, 2015, the Consolidated Appropriations Act of 2016 was passed by Congress with HOS language that was intended to provide additional certainty for the industry. The language was to require the FMCSA study to demonstrate results with statistically significant improvements in safety and driver health, among other things, before the agency could reinstate the 34-hour restart rule including the restrictions that became effective in July 2013. Unfortunately, the new legislation did not include language specifically stipulating that the industry would continue to operate under the old 2003 restart rules if the study does not conclude that the restrictions offer significant improvements. Due to this oversight, there is now a risk of the restart provisions being eliminated unless the error is corrected, or the restart provisions could be changed from the current rule.

On January 31, 2011, FMCSA issued proposed rules regarding the required installation and use of electronic logging devices (“ELDs”) by nearly all carriers to enhance the monitoring and enforcement of the driver HOS rules. Federal legislation required DOT to promulgate rules and regulations mandating the use of ELDs by July 2013 with full adoption for all trucking companies by no later than July 2015. However, FMCSA did not issue the final rule until December 10, 2015, and carriers have until December 2017 to adopt and use compliant ELDs. We are the recognized industry leader for electronic logging of driver hours as we proactively adopted a paperless log system in 1996 that was subsequently approved for our use by FMCSA in 1998. In order to improve compliance, and by extension safety performance and leveling the field upon which carriers compete, Werner supports a broad-based mandate for ELDs.

In May 2011, FMCSA published a final rule that (i) sets new standards that must be met before states issue commercial learner’s permits (“CLP”), (ii) revises the knowledge and skills testing standards that must be met to obtain both a CLP and a CDL, and (iii) improves anti-fraud measures with the CDL program. States were expected to comply with and start enforcing the new requirements as of July 8, 2015. In September 2013, FMCSA withdrew its proposed rule regarding minimum requirements for entry-level driver training programs and later formed the Entry-Level Driver Training Advisory Committee (“ELDTAC”) to conduct negotiated rulemaking to implement entry-level driver training provisions. In June 2015, the ELDTAC reached a consensus and forwarded its recommendations to FMCSA. FMCSA has not yet taken action on the ELDTAC's recommendations as the proposed rule has yet to published. This rule could materially impact the number of potential new drivers entering the industry, and we currently cannot predict how the adoption of such rules would affect our driver recruitment and the overall driver market.

WGL, through its domestic and global subsidiary companies, holds a variety 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 by the Transportation Security Administration (“TSA”) and Customs and Borders Protection (“CBP”) agencies 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.

Our operations are subject to various 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.

The EPA mandated a series of stringent engine emissions standards for all newly manufactured truck engines, which became effective in October 2002, January 2007 and January 2010, resulting in increases in the costs of new trucks. The 2010 regulations required a significant decrease in particulate matter (soot and ash) and nitrogen oxide emitted from on-road diesel engines. Engine manufacturers responded to the 2010 standards by modifying engines to produce cleaner combustion with selective catalytic reduction (“SCR”) technologies to remove pollutants from exhaust gases exiting the combustion chamber. The SCR technology also requires the ongoing periodic use of a urea-based diesel exhaust fluid. Trucks with 2010-standard engines have a higher purchase price than trucks manufactured to meet the 2007 standards but are more fuel efficient. As of December 31, 2015, nearly all of our company tractors had engines that comply with the 2010 emission standards.

The State of California enacted restrictions on transport refrigeration unit (“TRU”) emissions that require companies to operate compliant TRUs in California. The California regulations apply not only to California intrastate carriers, but also to carriers outside of California who wish to enter the state with TRUs. In January 2009, the EPA enabled California to phase in its Low-Emission TRU In-Use Performance Standards over several years. Enforcement of California’s in-use performance standards for TRU engines began in January 2010 for 2002 and older TRUs and will be phased in annually for later model years. We have complied with all compliance deadlines through December 31, 2015 that applied to model year 2008 and older TRU engines. California also required the registration of all California-based TRUs by July 31, 2009. For compliance purposes, we completed the California TRU registration process and continue to structure our plan to operate compliant TRUs over the next several years as the regulations apply to newer model years.

California also adopted regulations to improve the fuel efficiency of heavy-duty tractors that pull 53-foot or longer box-type trailers within the state. The tractors and trailers subject to these regulations must either use EPA SmartWay-certified tractors and trailers or retrofit their existing fleet with SmartWay-verified technologies that have been demonstrated to meet or exceed fuel savings percentages specified in the regulations. Examples of these technologies include tractor and trailer aerodynamics packages (such as tractor fairings and trailer skirts) and the use of low-rolling resistance tires on both tractors and trailers. Enforcement of these regulations for 2011 model year equipment began in January 2010 and is being phased in over several years for older equipment. In order to comply with the California Air Resources Board’s (“CARB”) fuel efficiency regulations, we submitted a large fleet compliance plan to CARB on June 30, 2010, to install skirting on our dry van trailers by certain deadlines through 2016. We will continue monitoring our compliance with these CARB regulations.

Various provisions of the North American Free Trade Agreement (“NAFTA”) may alter the competitive environment for shipping into and out of Mexico. We currently believe we are well prepared to respond to any changes that may result from this agreement. We conduct a substantial amount of business in international freight shipments to and from the United States and Mexico (see Note 10 in the Notes to Consolidated Financial Statements under Item 8 of Part II of this Form 10-K), and we believe we are one of the largest truckload carriers in terms of freight volume shipped to and from the United States and Mexico.

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 Truckload segment competes primarily with other truckload carriers. Logistics companies, intermodal companies, railroads, less-than-truckload carriers and private carriers provide competition for both our Truckload and VAS segments. Our VAS 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.

Internet Website

We maintain an Internet website where you can find additional information regarding our business and operations. The website address is www.werner.com. On the website, we make certain investor information available free of charge, including our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, stock ownership reports filed under Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any amendments to such reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act. This information is included on our website as soon as reasonably practicable after we electronically file or furnish such materials to the U.S. Securities and Exchange Commission (“SEC”). The website also includes Interactive Data Files required to be posted pursuant to Rule 405 of SEC Regulation S-T. We also provide our corporate governance materials, such as Board committee charters and our Code of Corporate Conduct, on our website free of charge, and we may occasionally update these materials when necessary to comply with SEC and NASDAQ rules or to promote the effective and efficient governance of our company. Information provided on our website is not incorporated by reference into this Form 10-K.

ITEM 1A. RISK FACTORS

The following risks and uncertainties may cause our actual results, business, financial condition and cash flows to materially differ from those anticipated in the forward-looking statements included in this Form 10-K. Caution should be taken not to place undue reliance on forward-looking statements made herein because such statements speak only to the date they were made. Unless otherwise required by applicable securities laws, we undertake no obligation or duty to revise or update any forward-looking

6

statements contained herein to reflect subsequent events or circumstances or the occurrence of unanticipated events. Also refer to the Cautionary Note Regarding Forward-Looking Statements in Item 7 of Part II of this Form 10-K.

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, 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 impact our results of operations and limit growth opportunities.

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 could affect our profitability.

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. 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 would be unable to obtain corresponding freight rate increases.

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, 2015, 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 Truckload segment. Logistics companies, intermodal companies, railroads, less-than-truckload carriers and private carriers also provide a lesser degree of competition in our Truckload segment, but such providers are more direct competitors in our VAS 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 of existing or future regulations could adversely affect our operations and profitability.

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 Regulation 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.

7

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 2015, our largest 5, 10 and 25 customers accounted for 27%, 45% and 63% of revenues, respectively. No single customer generated more than 10% of our revenues in 2015, and our largest customer accounted for 7% of our revenues in 2015. We do not have long-term contractual relationships with many of our key One-Way Truckload customers. Our contractual relationships with our Specialized Services customers are typically one to three years in length and may be terminated by either party upon 30 to 90 days’ notice following the expiration of the contract’s first year, and we review rates in these 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 VAS segment.

Our VAS segment is highly dependent on the services of third-party capacity providers, such as other truckload carriers, less-than-truckload carriers, railroads, ocean carriers and airlines. 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. 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 largely mitigated by the terms of NAFTA for Mexico and Canada. 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.

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 Fleet Truck Sales.

8

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 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 experience significant financial problems, we could experience difficulty in obtaining needed goods and services because of production interruptions or other reasons. Consequently, our business could be adversely affected.

We use our information systems extensively for day-to-day operations, and service disruptions could have an adverse impact on our operations.

The efficient operation of our business is highly dependent on our information systems. Much of our software was developed internally or by adapting purchased software applications to suit our needs. Our information systems are used for receiving and planning loads, dispatching drivers and other capacity providers, billing customers and providing financial reports. If any of our critical information systems fail or become unavailable, we would have to perform certain functions manually, which could temporarily affect our ability to efficiently manage our operations. We maintain information security policies to protect our systems and data from cyber security events and threats. We purchased redundant computer hardware systems and have our own off-site disaster recovery facility approximately ten miles from our headquarters for use in the event of a disaster. We took these steps to reduce the risk of disruption to our business operation if a disaster occurred. We believe any such disruption would be minimal or moderate; however, we cannot predict the degree to which any disaster would affect our information systems or disaster recovery facility. Any system failure, disruption, or security breach could interrupt or delay our operations, damage our reputation, cause us to lose customers, or impact our ability to manage our operations, any of which could have an adverse effect on our operations.

The Fleet Truck Sales network currently has six locations, which are located in certain of our terminals listed above. Our driver training schools currently operate in 15 locations.

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-insurance program with a qualified department 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’ compensation claims at year-end.

Since August 1, 2004, our self-insured retention (“SIR”) and deductible amount for liability claims has been $2.0 million, plus administrative expenses, for each occurrence involving bodily injury or property damage. We are also responsible for varying annual aggregate amounts of liability for claims in excess of the SIR/deductible. The following table reflects the SIR/deductible levels and aggregate amounts of liability for bodily injury and property damage claims since August 1, 2012:

Coverage Period	Primary Coverage	Primary  Coverage SIR/Deductible
August 1, 2012 – July 31, 2013	$5.0 million	$2.0 million  (1)
August 1, 2013 – July 31, 2014	$5.0 million	$2.0 million  (1)
August 1, 2014 – July 31, 2015	$5.0 million	$2.0 million  (1)
August 1, 2015 – July 31, 2016	$5.0 million	$2.0 million  (1)

(1) Subject to an additional $8.0 million aggregate in the $2.0 to $5.0 million layer.

10

Our primary insurance covers the range of liability under which we expect most claims to occur. If any liability claims are in excess of coverage amounts listed in the table above, such claims are covered under premium-based policies (issued by insurance companies) to coverage levels that our management considers adequate. For claims in excess of $5.0 million and less than $10.0 million, we are responsible for the first $5.0 million of claims in this layer. We are also responsible for administrative expenses for each occurrence involving bodily injury or property damage. See also Note 1 and Note 8 in the Notes to Consolidated Financial Statements under Item 8 of Part II of this Form 10-K.

We are responsible for workers’ compensation claims up to $1.0 million per claim and have premium-based insurance coverage for individual claims above $1.0 million. We also maintain a $29.8 million bond for the State of Nebraska and a $6.9 million bond for our workers’ compensation insurance carrier.

Overview:

We have two reportable segments, Truckload and VAS, 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 customers, we provide additional sources of truck capacity, alternative modes of transportation, a global 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 Truckload segment) or obtain qualified third-party capacity at a reasonable price (with respect to our VAS segment). Although our business volume is not highly concentrated, we may also be affected by our customers’ financial failures or loss of customer business.

Revenues for our Truckload segment operating units (One-Way Truckload and Specialized Services) 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 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 Truckload segment also generates a small amount of revenues categorized as non-trucking revenues, related to shipments delivered to or from Mexico where the Truckload 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. 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 Truckload 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 Truckload 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 2015 to 2014, 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. Our main fixed costs include depreciation expense for tractors and trailers and equipment licensing fees (included in taxes and licenses expense). The Truckload 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 four operating units within our VAS segment (Brokerage, Freight Management, Intermodal and WGL). Unlike our Truckload segment, the VAS 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 VAS 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. We evaluate the VAS segment's financial performance by reviewing the gross margin percentage (revenues less rent and purchased transportation expenses expressed as a percentage of revenues) and the operating income percentage. The gross margin percentage can be impacted by the rates charged to customers and the costs of securing third-party capacity. We generally do not have contracted long-term 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.

2015 Compared to 2014

Operating Revenues

Operating revenues decreased 2.1% in 2015 compared to 2014. When comparing 2015 to 2014, the Truckload segment revenues decreased $57.3 million, or 3.4%, and the VAS segment revenues increased $2.5 million, or 0.6%. The significantly lower fuel prices in 2015 compared to 2014 resulted in lower fuel surcharge revenues in the Truckload segment and lower revenues in the VAS segment.

Assessing freight demand within the Truckload segment, 2014 and 2015 were cyclically contrasting years. 2014 provided the benefits of gradually improving demand from a strengthening economy and constrained supply due to a tight driver market and increasing safety regulations. Freight demand in 2015 did not strengthen as the year progressed, as the rate of economic growth slowed. The truckload sector also experienced supply increases in 2015 as small carrier confidence rose as a result of better rates in 2014 and much lower fuel prices beginning in late 2014. Finally, as 2015 ended, truckload supply began to stabilize as truck orders declined significantly and safety regulators finalized the electronic logging device regulations. Freight demand thus far in 2016 has been seasonally consistent with the same periods of 2013, 2012, 2011. Compared to the same periods in 2015 and 2014, freight demand was not as strong.

Trucking revenues, net of fuel surcharge, increased 5.9% in 2015 compared to 2014 due to a 3.7% increase in average number of tractors in service and a 2.1% increase in average revenues per tractor per week, net of fuel surcharge revenues. Average revenues per total mile, net of fuel surcharge revenues, increased 2.6% and average miles per truck declined by 0.5% in 2015 compared to 2014.

We continue to make progress implementing sustainable rate increases with our customers during 2015. These efforts are on-going as we move forward in 2016 and work to recoup the cost increases associated with more expensive equipment, a shrinking supply of qualified drivers and an increasingly challenging regulatory environment.

The average number of tractors in service in the Truckload segment increased 3.7% to 7,271 in 2015 from 7,013 in 2014, an increase of 258 tractors. Following an ongoing and intense company-wide focus to improve our driver recruiting and retention, we ended 2015 with 7,450 tractors in the Truckload segment (3,675 in our Specialized Services unit and 3,775 in our One-Way Truckload unit). 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 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. These revenues decreased 39.2% to $212.5 million in 2015 from $349.8 million in 2014 because of lower average fuel prices in 2015. 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 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.

VAS revenues are 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. VAS also recorded revenue and brokered freight expense of $1.3 million in 2015 and $2.9 million in 2014 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. VAS revenues increased 0.6% to $393.2 million in 2015 from $390.6 million in 2014. VAS gross margin dollars increased 17.3% to $61.0 million in 2015 from $52.0 million in 2014, and the VAS gross margin percentage improved to 15.5% in 2015 from 13.3% in 2014. VAS results for 2014 were negatively impacted by lower gross margin percentages for contractual business due to rising third-party carrier costs in a tight capacity market as well as regional capacity issues related to the second quarter 2014 start-up of a large VAS customer. We addressed several customer pricing, contractual and operational issues within VAS in fourth quarter 2014 which resulted in improved VAS financial performance in 2015. The VAS operating income percentage improved to 4.3% in 2015 from 1.9% in 2014.

Operating Expenses

Our operating ratio (operating expenses expressed as a percentage of operating revenues) was 90.4% in 2015 compared to 92.5% in 2014. Expense items that impacted the overall operating ratio are described 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 VAS.

Salaries, wages and benefits increased $55.9 million or 9.6% in 2015 compared to 2014 and increased 3.3% as a percentage of operating revenues. The higher dollar amount of salaries, wages and benefits expense was due primarily to higher driver salaries and payroll related fringe benefits due to higher driver pay rates and more company trucks and miles in 2015. We also recorded a total of $3.9 million of expense in 2015 related to a class action suit involving an employment related claim and a separation agreement for an executive resignation. When evaluated on a per-mile basis, driver and non-driver salaries, wages and benefits increased as well, which we attribute primarily to higher driver pay. In mid-August 2014, we increased pay by varying percentage amounts for many drivers within our One-Way Truckload unit. We also increased driver pay in multiple Dedicated fleets in 2014 and 2015. Non-driver salaries, wages and benefits in the non-trucking VAS segment decreased 1.6% in 2015 compared to 2014.

We renewed our workers' compensation insurance coverage for the policy year beginning April 1, 2015. 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 2015 were similar to those for the previous policy year.

The driver recruiting market remained very challenging in 2015. Several difficult market factors persisted, including a declining number of, and increased competition for, driver training school graduates, a gradually declining national unemployment rate, aging truck driver demographics and increased truck safety regulations. Following our mid-August 2014 pay changes and an ongoing and intense company-wide focus to improve our driver and retention, our driver retention metrics improved. During fourth

17

quarter 2015, we announced strategic and targeted company driver and independent contractor per-mile increases in our One-Way Truckload business unit, totaling slightly more than $10 million on an annualized basis to nearly 20% of our drivers. Most of these increases became effective January 2016. We are unable to predict whether we will experience future driver shortages. If such a 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 decreased $141.5 million or 40.9% in 2015 compared to 2014 and decreased 6.4% as a percentage of operating revenues due to (i) lower average diesel fuel prices and (ii) improved miles per gallon ("mpg"). Average diesel fuel prices in 2015 were $1.18 per gallon lower than in 2014, a 41% decrease. These decreases were partially offset by higher company truck miles in 2015.

We continue to employ measures to improve our fuel mpg, including (i) limiting truck 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, more aerodynamic truck 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 certain tractors with engines that meet the 2010 EPA emission standards). 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 of 2016, the average diesel fuel price per gallon was approximately $0.71 lower than the average diesel fuel price per gallon in the same period of 2015 and approximately $0.75 lower than the average for first quarter 2015.

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, 2015, we had no derivative financial instruments to reduce our exposure to fuel price fluctuations.

Supplies and maintenance increased $1.7 million or 0.9% in 2015 compared to 2014 and increased 0.3% as a percentage of operating revenues. Driver advertising and other driver related expenses were higher in 2015 than in 2014. These increases were partially offset by lower tractor maintenance costs in 2015 due to a lower average age of company trucks in 2015 when compared to 2014.

Taxes and licenses increased $4.2 million or 4.9% in 2015 compared to 2014 and increased 0.3% as a percentage of operating revenues due to more miles in 2015 than in 2014, resulting from an increase in the average tractors in service, and an increase in property taxes. These increases were partially offset by a higher mpg in 2015 compared to 2014. An improved mpg results in fewer gallons of diesel fuel purchased and consequently less fuel taxes paid.

Insurance and claims increased $0.5 million or 0.6% in 2015 compared to 2014 and increased 0.2% as a percentage of operating revenues. The increase in 2015 compared to 2014 is primarily the result of higher expense on large dollar liability claims, partially offset by a decrease in expense related to cargo claims. Most 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, 2015, and continue 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. We maintain liability insurance coverage with insurance carriers substantially in excess of the $10.0 million per claim. See Item 3 of Part I of this Form 10-K for information on our bodily injury and property damage coverage levels since August 1, 2012. Our liability and cargo insurance premiums for the policy year that began August 1, 2015, are slightly lower than premiums for the previous policy year on a per-mile basis.

Depreciation increased $16.2 million or 9.2% in 2015 compared to 2014 and increased 0.9% as a percentage of operating revenues. This expense increase is due primarily to the higher cost of new trucks purchased compared to the cost of used trucks that were sold, as well as the growth in the number of company trucks. In addition, the purchase of new trailers to replace older used trailers which were fully depreciated also contributed to the increase in depreciation expense.

Depreciation expense has been historically affected by a series of changes to engine emissions standards imposed by the EPA that became effective in October 2002, January 2007 and January 2010, resulting in increased truck purchase costs. Trucks with 2010-standard engines have a higher purchase price than trucks manufactured to meet the 2007 standards, but the 2010-standard engines are more fuel efficient. As of December 31, 2015, nearly all of our company tractors had engines that comply with the 2010 emissions standards.

18

Rent and purchased transportation expense decreased $18.2 million or 3.6% in 2015 compared to 2014 and decreased 0.4% as a percentage of operating revenues. Rent and purchased transportation expense consists mostly of payments to third-party capacity providers in the VAS segment and other non-trucking operations and payments to independent contractors in the Truckload segment. The payments to third-party capacity providers generally vary depending on changes in the volume of services generated by the VAS segment. VAS rent and purchased transportation expense decreased $6.5 million, despite higher VAS revenues, and decreased to 84.5% of VAS revenues in 2015 from 86.7% in 2014. This decrease was due primarily to our ongoing efforts to address customer pricing, contractual and operational issues within VAS.

Rent and purchased transportation expense for the Truckload segment decreased $13.0 million in 2015 compared to 2014. This decrease is due primarily to lower fuel prices that resulted in lower reimbursement to independent contractors for fuel and a higher average independent contractor settlement rate per mile in 2015 compared to 2014. In mid-August 2014 and in November 2015, we increased the per-mile settlement rate for certain independent contractors. Independent contractor miles as a percentage of total miles were 11.9% in 2015 and 12.1% in 2014.

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. We have historically 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.

Communications and utilities increased $0.9 million or 6.3% in 2015 compared to 2014 but did not change as a percentage of operating revenues. The increase is due to higher equipment tracking expenses and higher communication costs.

Other operating expenses decreased $5.9 million in 2015 compared to 2014 and decreased 0.3% as a percentage of operating revenues. Gains on sales of assets (primarily used trucks 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 increased to $23.2 million in 2015 from $19.3 million in 2014, a $3.9 million increase. In 2015, we sold more trucks and trailers than in 2014. We realized higher average gains per trailer sold, while average gains per truck sold were flat. The used truck market weakened in fourth quarter 2015, causing lower pricing. We expect this trend to continue in 2016. We also realized $0.7 million in gains from the sale of real estate in 2015 compared to $1.6 million in 2014. Other operating expenses were lower in 2015 than in 2014.

Other Expense (Income)

Other expense (income) increased $1.0 million in 2015 compared to 2014 and increased 0.1% as a percentage of operating revenues. Interest expense was higher in 2015 compared to 2014 because we recorded a full year of interest expense in 2015 after entering into an interest rate swap agreement in September 2014 that effectively fixed our interest rate at 2.5% for five years on debt of $75 million.

Income Taxes

Our effective income tax rate (income taxes expressed as a percentage of income before income taxes) decreased to 38.5% for 2015 from 39.0% in 2014. The lower income tax rate in 2015 is primarily attributed to favorable tax adjustments for the remeasurement of uncertain tax positions in 2015 and the effect of higher pre-tax income which caused non-deductible expenses to comprise a lower percentage.

2014 Compared to 2013

Operating Revenues

Operating revenues increased 5.4% in 2014 compared to 2013. When comparing 2014 to 2013, the Truckload segment revenues increased $44.3 million, or 2.7%, and the VAS segment revenues increased $29.3 million, or 8.1%.

Within the Truckload segment, freight demand was strong in 2014. Freight demand (as measured by our daily morning ratio of loads available to trucks available in our One-Way Truckload network) showed consistent strength throughout the year, and we were overbooked (more available freight than available trucks at the beginning of each business day) nearly every week of 2014. The improved freight market dynamics began showing year-over-year improvement for Werner in mid-November 2013, and that favorable trend continued through 2014. A tight capacity market in 2014 combined with a gradually firming economy as 2014 progressed were the primary contributing factors.

19

Trucking revenues, net of fuel surcharge, increased 3.5% in 2014 compared to 2013 due to a 5.7% increase in average revenues per tractor per week, net of fuel surcharge, partially offset by a 2.1% decrease in the average number of tractors in service. Average miles per truck improved by 2.7% and our empty mile percentage was 3.1% lower in 2014 than in 2013. Average revenues per total mile, net of fuel surcharge, increased 3.0% in 2014 compared to 2013. Several factors had a positive impact on our average revenues per tractor per week and profitability, while at the same time reduced the percentage increase in our revenue per total mile. Our average trip length increased by 4.4% in 2014 compared to 2013, and longer length of haul shipments generally have a lower rate per mile due to productivity benefits. Noting the improved freight market in 2014 compared to 2013, during 2014 we accepted less brokerage freight (in which rates are inclusive of fuel) and instead supported our customers with additional capacity priced with a base rate per mile and a fuel surcharge per mile. Finally, customer changes in fuel surcharge programs had a neutral impact on profitability but an adverse effect on revenue per total mile, net of fuel surcharge. A few large customers modified their fuel surcharge programs to "zero peg" in the past 12 months, which shifted revenues from base rates to fuel surcharges. A zero peg fuel surcharge program starts with a base fuel price per gallon (the minimum price for fuel, above which a customer pays fuel surcharge) of zero rather than a base fuel price per gallon more commonly ranging from $1.10 to $1.20.

The average number of tractors in service in the Truckload segment decreased 2.1% to 7,013 in 2014 from 7,162 in 2013, a decrease of 149 tractors. We ended 2014 with 7,050 tractors in the Truckload segment (3,690 in our Specialized Services unit and 3,360 in our One-Way Truckload unit). In mid-August 2014, we increased pay by varying percentage amounts for many drivers in certain fleets within our One-Way Truckload unit. After these driver pay changes, our driver and truck count recovered and increased from July 2014 levels.

Trucking fuel surcharge revenues decreased 1.4% to $349.8 million in 2014 from $354.6 million in 2013 because of lower average fuel prices in 2014, which more than offset the impact of the less brokerage freight and zero peg fuel surcharge items described above and the effect of higher miles.

VAS revenues are 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. VAS also recorded revenue and brokered freight expense of $2.9 million in 2014 and $4.5 million in 2013 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. VAS revenues increased 8.1% to $390.6 million in 2014 from $361.4 million in 2013. VAS gross margin dollars decreased 6.8% to $52.0 million in 2014 from $55.8 million in 2013, and other operating expenses increased $3.3 million or 8.1%. VAS results for 2014 (especially mid-year) were negatively impacted by lower gross margin percentages for contractual business due to rising third-party carrier costs in a tight capacity market as well as regional capacity issues related to the second quarter 2014 start-up of a large VAS customer.

Operating Expenses

Our operating ratio was 92.5% in 2014 compared to 93.1% in 2013. Expense items that impacted the overall operating ratio are described 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 VAS.

Salaries, wages and benefits increased $38.6 million or 7.1% in 2014 compared to 2013 and increased 0.4% as a percentage of operating revenues. The higher dollar amount of salaries, wages and benefits expense was due primarily to higher driver and non-driver salaries. When evaluated on a per-mile basis, driver and non-driver salaries, wages and benefits increased as well, which we attribute primarily to higher driver pay. In mid-August 2014, we increased pay by varying percentage amounts for many drivers within our One-Way Truckload unit. In 2014, we also increased driver pay in multiple Dedicated fleets, most of which were funded by customer rate increases to ensure capacity. Non-driver salaries, wages and benefits in the non-trucking VAS segment decreased 0.3% in 2014 compared to 2013.

We renewed our workers' compensation insurance coverage for the policy year beginning April 1, 2014. Our coverage levels were the same as the prior policy year. We continued to maintain a self-insurance retention of $1.0 million per claim. Our workers' compensation insurance premiums for the policy year beginning April 2014 were similar to those for the previous policy year.

The driver recruiting and retention market was more challenging in 2014 compared to 2013. We hired 3.4% fewer drivers in 2014 compared to 2013, and the difficult driver market made it challenging to achieve our truck goal for the Truckload segment. We believe that a declining number of, and increased competition for, driver training school graduates, a gradually declining national unemployment rate and job competition from the housing construction and manufacturing industries were all contributing factors. Following our mid-August pay changes, our driver retention metrics improved.

20

Fuel decreased $25.7 million or 6.9% in 2014 compared to 2013 and decreased 2.1% as a percentage of operating revenues due to (i) lower average diesel fuel prices and (ii) slightly improved miles per gallon ("mpg"). Average diesel fuel prices in 2014 were 19 cents per gallon lower than in 2013, a 6% decrease. These decreases were partially offset by higher company truck miles.

During 2014, 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 2014 compared to 2013. However, fuel savings from the mpg improvement is partially offset by higher depreciation expense and the additional cost of diesel exhaust fluid.

Supplies and maintenance increased $9.3 million or 5.2% in 2014 compared to 2013 but did not change as a percentage of operating revenues. Driver advertising and other driver related expenses were higher in 2014 than in 2013. Increased over the road tractor and trailer maintenance also contributed to the increase in this expense category, some of which can be attributed to severe weather conditions in first quarter 2014.

Taxes and licenses decreased $1.2 million or 1.4% in 2014 compared to 2013 and decreased 0.3% as a percentage of operating revenues due to improvement in the company truck fuel mpg, despite driving more miles in 2014. An improved mpg results in fewer gallons of diesel fuel purchased and consequently less fuel taxes paid.

Insurance and claims increased $9.2 million or 12.9% in 2014 compared to 2013 and increased 0.2% as a percentage of operating revenues. The increase in 2014 compared to 2013 is primarily the result of an increase in the reserves for prior period claims (unfavorable development) related to large dollar liability claims. Higher expense on new smaller dollar liability claims was nearly offset by better development on small claims (favorable development in 2014 compared to unfavorable development in 2013). We renewed our liability insurance policies on August 1, 2014, 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, 2014, are slightly lower than premiums for the previous policy year on a per-mile basis.

Depreciation increased $4.0 million or 2.3% in 2014 compared to 2013 but decreased 0.2% as a percentage of operating revenues. This expense increase is due primarily to the higher cost of new trucks purchased compared to the cost of used trucks that were sold. In addition, the purchase of new trailers to replace older used trailers which were fully depreciated also contributed to the increase in depreciation expense. These increases were partially offset by lower depreciation on auxiliary power units that were sold with the older used trucks and not replaced.

Rent and purchased transportation expense increased $41.9 million or 9.2% in 2014 compared to 2013 and increased 0.8% as a percentage of operating revenues. VAS rent and purchased transportation expense increased $33.0 million and increased to 86.7% of VAS revenues in 2014 from 84.6% in 2013. This increase was due primarily to rising third-party carrier costs in a tight capacity market as well as regional capacity issues related to the second quarter 2014 start-up of a large VAS customer.

Rent and purchased transportation expense for the Truckload segment increased $5.3 million in 2014 compared to 2013. This increase is due primarily to higher third-party capacity provider costs for shipments delivered to or from Mexico because of volume increases and a higher average independent contractor pay per mile in 2014 compared to 2013. In August 2014, we increased the per-mile settlement rate for certain owner-operators. Independent contractor miles as a percentage of total miles were 12.1% in 2014 and 12.2% in 2013.

Communications and utilities increased $0.7 million or 5.3% in 2014 compared to 2013 but did not change as a percentage of operating revenues. The increase is due to using a new driver route navigation program and higher other communication costs.

Other operating expenses increased $13.1 million or 159.4% in 2014 compared to 2013 and increased 0.6% as a percentage of operating revenues. Gains on sales of assets increased to $19.3 million in 2014 from $16.4 million in 2013, a $2.9 million increase. In 2014, we realized lower average gains per truck sold, higher average gains per trailer sold and sold more trucks and trailers than in 2013. We also realized $1.6 million in gains from the sale of real estate in 2014 compared to $1.8 million in 2013. Other operating expenses were higher in 2014 than in 2013.

Other Expense (Income)

Other expense (income) increased $0.3 million or 15.1% in 2014 compared to 2013 and did not change as a percentage of operating revenues. Interest expense was higher in 2014 compared to 2013 because we had a higher amount of average debt outstanding, and we entered into an interest rate swap agreement in September 2014 that effectively fixed our interest rate at 2.5%.

21

Income Taxes

Our effective income tax rate (income taxes expressed as a percentage of income before income taxes) increased to 39.0% for 2014 from 38.8% in 2013. The higher income tax rate is primarily attributed to a smaller amount of favorable tax adjustments for the remeasurement of uncertain tax positions in 2014 than in 2013, partially offset by the benefit of prior year state income tax refunds received in 2014.

Liquidity and Capital Resources:

During the year ended December 31, 2015, we generated cash flow from operations of $370.4 million, a 79.3% increase ($163.8 million), compared to the year ended December 31, 2014. This increase in net cash provided by operating activities is attributed primarily to a $76.6 million increase from general working capital activities (including a $50.8 million increase in cash flows related to accounts receivable due to the timing of customer payments) and a $25.1 million increase in net income. Our income tax payments were also $41.6 million lower in 2015 due to the timing of enacting tax regulation changes at the end of 2014 and 2015. Cash flow from operations decreased $25.9 million in 2014 from 2013, or 11.1%. This decrease is attributed primarily to a $14.6 million decrease in cash flows related to accounts receivable and a $10.8 million increase in income tax payments. We were able to make net capital expenditures, pay dividends and repurchase company stock with the net cash provided by operating activities and existing cash balances, supplemented by net borrowings under our existing credit facilities.

Net cash used in investing activities increased by $132.0 million to $335.5 million in 2015 from $203.5 million in 2014 and increased by $63.2 million from $140.3 million in 2013. Net property additions (primarily revenue equipment) were $351.5 million for the year ended December 31, 2015 compared to $212.3 million during the same period of 2014 and $151.9 million during 2013. Net property additions were higher in 2015 and 2014 than in 2013 because starting in the second half of 2014, we increased our capital expenditures to lower the average age of our truck fleet. As of December 31, 2015, we were committed to property and equipment purchases of approximately $112.0 million. We currently estimate net capital expenditures (primarily revenue equipment) in 2016 to be in the range of $400 million to $450 million, which we expect will enable us to further reduce the average age of our truck fleet. If the freight market shows significant weakness during 2016, we will consider adjusting our capital expenditures accordingly. We intend to fund these net capital expenditures in 2016 through cash flow from operations and financing available under our existing credit facilities, as management deems necessary.

Net financing activities used $25.0 million in 2015, $3.7 million in 2014 and $83.5 million in 2013. During the year ended December 31, 2015, we borrowed and repaid $10.0 million of debt. Our outstanding debt at December 31, 2015 totaled $75.0 million. During 2014, we borrowed $85.0 million and repaid $50.0 million of debt, and in 2013 we borrowed $10.0 million and repaid $60.0 million. We also made a $3.1 million note payment in 2015. We paid quarterly dividends of $15.1 million in 2015, $14.4 million in 2014 and $14.6 million in 2013. We increased our quarterly dividend rate by $0.01 per share, or 20%, beginning with the dividend paid in October 2015. Financing activities for the year ended December 31, 2015, also included common stock repurchases of 225,000 shares at a cost of $6.4 million, compared to $30.6 million in 2014 (1,200,000 shares) and $20.1 million in 2013 (821,091 shares). From time to time, the Company has repurchased, and may continue to repurchase, shares of the Company’s common stock. The timing and amount of such purchases depends on stock market conditions and other factors. As of December 31, 2015, the Company had purchased 3,287,291 shares pursuant to our current Board of Directors repurchase authorization and had 4,712,709 shares remaining available for repurchase.

Management believes our financial position at December 31, 2015 is strong. As of December 31, 2015, we had $31.8 million of cash and cash equivalents and $935.7 million of stockholders’ equity. Cash is invested primarily in government portfolio money market funds. As of December 31, 2015, 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, 2015), of which we had borrowed $75.0 million. The remaining $250.0 million of credit available under these facilities is reduced by the $31.0 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.

As of December 31, 2015, we had unsecured committed credit facilities with three banks as well as a term commitment with one of these banks. We had with Wells Fargo Bank, N.A., a $100 million credit facility which will expire on July 12, 2020, and a $75 million term commitment with principal due and payable on September 15, 2019. On July 13, 2015, we amended our existing credit agreement, dated June 1, 2012, as previously amended, with Wells Fargo Bank, N.A. This amendment lowered the maximum principal amount of the unsecured line of credit to $100 million from $175 million and extended the term of the credit agreement to July 12, 2020. Also on July 13, 2015, we entered into a new credit agreement with U.S. Bank, N.A. The new credit agreement is an unsecured line of credit of $75 million and expires on July 13, 2020. On March 5, 2015, we replaced our existing $75 million credit agreement with BMO Harris Bank, N.A., with a new credit agreement. The new BMO Harris Bank, N.A., agreement includes a $75 million credit facility which will expire on March 5, 2020. Borrowings under these credit facilities and term note bear variable interest (0.93% at December 31, 2015) based on the London Interbank Offered Rate (“LIBOR”), with interest on the term note 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, 2015. The credit available under these 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, 2015, we had recorded a $7.7 million liability for unrecognized tax benefits. We are unable to reasonably determine when the $7.7 million categorized as “period unknown” will be settled.

Off-Balance Sheet Arrangements:

We began leasing certain tractors under non-cancelable operating leases in May 2011. During second quarter 2015, we satisfied all lease agreements and have no future payment obligation under these leases at December 31, 2015.

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.

23

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 physical damage losses and workers’ compensation. The insurance and claims accruals (current and non-current) are recorded at the estimated ultimate payment amounts and are based upon individual case estimates (including negative development) and estimates of incurred-but-not-reported losses using loss development factors based upon past experience. An actuary reviews our 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 in the years when those temporary differences are expected 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 established for the amount of deferred income tax assets that are determined not to be realizable. A valuation allowance for deferred income tax assets has not been deemed necessary due to our profitable operations. Accordingly, if facts or financial circumstances change and consequently impact the likelihood of realizing the deferred income tax assets, we would need to apply management’s judgment to determine the amount of valuation allowance required in any given period. 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 over the past three years.

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.

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, 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, 2015, 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. 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 losses were $3.9

24

million in 2015, $3.6 million in 2014, and $0.5 million in 2013 and were recorded in accumulated other comprehensive loss within stockholders’ equity in the Consolidated Balance Sheets. The exchange rate between the Mexican Peso and the U.S. Dollar was 17.21 Pesos to $1.00 at December 31, 2015 compared to 14.72 Pesos to $1.00 at December 31, 2014 and 13.08 Pesos to $1.00 at December 31, 2013.

Interest Rate Risk

We manage interest rate exposure through a mix of variable rate debt and interest rate swap agreements. We had $75.0 million of debt outstanding at December 31, 2015, for which the interest rate is effectively fixed at 2.5% through September 2019 with an interest rate swap agreement. Interest rates on our unused credit facilities are based on the LIBOR. Increases in interest rates could impact our annual interest expense on future borrowings. As of December 31, 2015, we had one effective interest rate swap agreement with a notional amount of $75.0 million to reduce our exposure to interest rate increases.

25

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders

Werner Enterprises, Inc.:

We have audited the accompanying consolidated balance sheets of Werner Enterprises, Inc. and subsidiaries (the Company) as of December 31, 2015 and 2014, and the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2015. In connection with our audits of the consolidated financial statements, we have also audited the financial statement schedule listed in Item 15(a)(2) of this Form 10-K. These consolidated financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements and the financial statement schedule based on our audits.

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

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Werner Enterprises, Inc. and subsidiaries as of December 31, 2015 and 2014, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2015, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Werner Enterprises, Inc.’s internal control over financial reporting as of December 31, 2015, 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 26, 2016 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Business: Werner Enterprises, Inc. (the “Company”) is a truckload transportation and logistics company 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. For the year ended December 31, 2015, our ten largest customers comprised 45% of our revenues. For the years ended December 31, 2014 and 2013, our ten largest customers comprised 41% and 40%, respectively, of our revenues. No single customer generated more than 10% of the Company’s total revenues in 2015, 2014, and 2013.

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 useful lives and salvage values of property and equipment, accrued liabilities for insurance and claims, estimates for incomes 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, and changes in such accounts are reported as a financing activity in the Consolidated Statements of Cash Flows.

Trade Accounts Receivable: We record trade accounts receivable at the invoiced amounts, net of an allowance for doubtful accounts. The allowance for doubtful accounts is our estimate of the amount of probable credit losses and revenue adjustments in our existing accounts receivable. 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 or market 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:

	Lives	Salvage Values
Building and improvements	30 years	0%
Tractors	80 months	0%
Trailers	12 years	$1,000
Service and other equipment	3-10 years	0%

32

Long-Lived Assets: 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. 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 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 Statements of 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 insurance and claims accruals are based upon individual case estimates (including negative development) and estimates of incurred-but-not-reported losses using loss development factors based upon past experience. Actual costs related to insurance and claims have not differed materially from estimated accrued amounts for all years presented. An actuary reviews our undiscounted self-insurance reserves for bodily injury and property damage claims and workers’ compensation claims at year-end.

For the years ended December 31, 2015, 2014, and 2013 our self-insured retention (“SIR”) and deductible amount for liability claims is $2.0 million plus administrative expenses, for each occurrence involving bodily injury or property damage. We are also responsible for varying annual aggregate amounts of liability for claims in excess of the SIR/deductible. Liability claims in excess of these aggregates are covered under premium-based policies (issued by insurance companies) to coverage levels that our management considers adequate. 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 million per claim, with premium-based insurance coverage for claims exceeding this amount. We also maintain a $29.8 million bond for the State of Nebraska and a $6.9 million bond for our workers’ compensation insurance carrier.

Under these insurance arrangements, we maintained $31.0 million in letters of credit as of December 31, 2015.

Revenue Recognition: The Consolidated Statements of Income reflect recognition of operating revenues (including fuel surcharge revenues) and related direct costs when the shipment is delivered. 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) 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/or (iv) have credit risk 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 revenues net of those expenses related to third-party providers.

Derivative Financial Instrument: We manage our interest rate risk through an interest rate swap. The derivative financial instrument is recognized in the Consolidated Balance Sheets at fair value. The effect on earnings from recognizing the fair value of this derivative financial instrument depends on its intended use, its hedge designation, and its effectiveness in offsetting changes in the fair value of the exposure it is hedging. Changes in the fair value of the instrument designated to reduce or eliminate adverse fluctuations in the fair values of recognized assets and liabilities and unrecognized firm commitments are reported currently in earnings along with changes in the fair values of the hedged items. Changes in the effective portion of the fair value of the instrument used to reduce or eliminate adverse fluctuations in cash flows of anticipated or forecasted transactions is reported in equity as a component of accumulated other comprehensive income (loss), net of income tax effects. Amounts in accumulated other comprehensive income (loss) are reclassified to earnings when the related hedged items affect earnings or the anticipated transactions are no longer probable. Amounts reported in earnings are classified consistent with the item being hedged.

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 Sheets and as a separate component of comprehensive income in the Consolidated Statements of Comprehensive Income.

33

Income Taxes: We use the asset and liability method in accounting for income taxes. Under this method, deferred 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 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.

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).

	Years Ended December 31,
	2015		2014		2013
Net income	$	123,714	$	98,650	$	86,785
Weighted average common shares outstanding	71,957		72,122		72,866
Dilutive effect of stock-based awards	599		616		562
Shares used in computing diluted earnings per share	72,556		72,738		73,428
Basic earnings per share	$	1.72	$	1.37	$	1.19
Diluted earnings per share	$	1.71	$	1.36	$	1.18

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, restricted stock units 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 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.

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, 2015 and 2014, comprehensive income consists of net income, foreign currency translation adjustments and change in fair value of interest rate swap. For the year ended December 31, 2013, comprehensive income consists of net income and foreign currency translation adjustments.

New Accounting Pronouncements Adopted: We did not adopt any new accounting standards during 2015.

Accounting Standards Updates Not Yet Effective: On May 28, 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In July 2015, the FASB voted to approve a one-year deferral of the effective date of the new revenue recognition standard and to permit early adoption but no earlier than the original effective date (annual periods beginning after December 15, 2016); such decisions were documented in the FASB's ASU No. 2015-14 “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date.” As a result of the deferral, the new standard will become effective for us beginning January 1, 2018, unless we choose to adopt early on January 1, 2017. The standard permits the use of either the

34

retrospective or cumulative effect transition method. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures and have not yet selected a transition method.

In April 2015, the FASB issued ASU No. 2015-3, “Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs,” which requires debt issuance costs to be recorded as a direct reduction of the debt liability on the balance sheet rather than as an asset. The provisions of this update are effective as of January 1, 2016, and are not expected to have a material effect on our consolidated financial position, results of operations or cash flows.

In July 2015, the FASB issued ASU No. 2015-11, “Inventory: Simplifying the Measurement of Inventory,” which requires inventory to be recorded at the lower of cost and net realizable value. The provisions of this update are effective as of January 1, 2017, and are not expected to have a material effect on our consolidated financial position, results of operations or cash flows.

In November 2015, the FASB issued ASU No. 2015-17, “Income Taxes: Balance Sheet Classification of Deferred Taxes,” which requires presentation of deferred tax assets and liabilities as non-current in the balance sheet. The provisions of this update are effective as of January 1, 2017, and early adoption is permitted as of the beginning of an interim or annual reporting period. The amendments in the update are not expected to have a material effect on our consolidated financial position, results from operations or cash flows.

Other ASUs not identified above and which are not effective until after December 31, 2015 are not expected to have a material effect on our consolidated financial position, results of operations or cash flows.

(2) CREDIT FACILITIES

As of December 31, 2015, we had unsecured committed credit facilities with three banks as well as a term commitment with one of these banks. We had with Wells Fargo Bank, N.A., a $100.0 million credit facility which will expire on July 12, 2020, and a $75.0 million term commitment with principal due and payable on September 15, 2019. On July 13, 2015, we amended our existing credit agreement, dated June 1, 2012, as previously amended, with Wells Fargo Bank, N.A. This amendment lowered the maximum principal amount of the unsecured line of credit to $100.0 million from $175.0 million and extended the term of the credit agreement to July 12, 2020 from May 31, 2016. Also on July 13, 2015, we entered into a new credit agreement with U.S. Bank, N.A. The new credit agreement is an unsecured line of credit of $75.0 million and expires on July 13, 2020. We also had a $75.0 million credit facility with BMO Harris Bank, N.A., which will expire on March 5, 2020. On March 5, 2015, we replaced our existing $75.0 million credit agreement with BMO Harris Bank, N.A., with a new credit agreement. The new BMO Harris Bank, N.A., agreement includes a $75.0 million credit facility which will expire on March 5, 2020. Borrowings under these credit facilities and term note bear variable interest (0.9305% at December 31, 2015) based on the London Interbank Offered Rate (“LIBOR”), with interest on the term note effectively fixed at 2.5% with an interest rate swap agreement.

As of December 31, 2015 and 2014, our outstanding debt totaled $75.0 million. The $325.0 million of credit available under these facilities is further reduced by $31.0 million in stand-by letters of credit under which we are obligated. Each of the debt agreements includes, among other things, financial covenants requiring us (i) not to exceed a maximum ratio of total debt to total capitalization and/or (ii) not to exceed a maximum ratio of total funded debt to earnings before interest, income taxes, depreciation and amortization (as such terms are defined in each credit facility). At December 31, 2015, we were in compliance with these covenants.

At December 31, 2015, the aggregate future maturities of long-term debt by year are as follows (in thousands):

2016	$	—
2017	—
2018	—
2019	75,000
2020	—
Total	$	75,000

The carrying amounts of our long-term debt approximate fair value due to the duration of the notes and the variable interest rates.

35

(3) NOTES RECEIVABLE

Notes receivable are included in other current assets and other non-current assets in the Consolidated Balance Sheets. At December 31, notes receivable consisted of the following (in thousands):

	December 31,
	2015		2014
Independent contractor notes receivable	$	38,450	$	19,021
Other notes receivable	7,474		6,780
	45,924		25,801
Less current portion	11,597		8,464
Notes receivable – non-current	$	34,327	$	17,337

We provide financing to some individuals who want to become independent contractors by purchasing a tractor from us and leasing their services to us. At December 31, 2015, we had 682 notes receivable from these independent contractors and at December 31, 2014, we had 472 such notes receivable. We maintain a primary security interest in the tractor until the independent contractor pays the note balance in full.

(4) LEASES

In 2011, we entered into leases of certain tractors under operating leases which expired in 2015. Rental expense for these leases was included in rent and purchased transportation expense within the Consolidated Statements of Income. At December 31, 2015, we had no future lease payments under non-cancelable revenue equipment operating leases.

Rental expense under these non-cancelable revenue equipment operating leases for the years ended December 31, 2015, 2014, and 2013 was as follows (in thousands):

2015	$	584
2014	1,565
2013	1,593

(5) INCOME TAXES

Income tax expense consisted of the following (in thousands):

	Years Ended December 31,
	2015		2014		2013

Total income tax expense	$	77,447		$	63,124		$	54,926

At December 31, deferred tax assets and liabilities consisted of the following (in thousands):

	December 31,

Deferred tax assets:
Insurance and claims accruals	$	71,285	$	74,651

Other	2,356		2,634
Gross deferred tax liabilities	340,165		305,175
Net deferred tax liability	$	246,264	$	207,540

These amounts are presented in the accompanying Consolidated Balance Sheets as of December 31 as follows (in thousands):

	December 31,
	2015		2014
Current deferred tax asset	$	28,037	$	34,066
Non-current deferred tax liability	274,301		241,606
Net deferred tax liability	$	246,264	$	207,540

We have not recorded a valuation allowance because we believe that all deferred tax assets are more likely than not to be realized as a result of our historical profitability, future taxable income and reversal of deferred tax liabilities.

We recognized a $551 thousand decrease in the net liability for unrecognized tax benefits for the year ended December 31, 2015 and a $37 thousand decrease for the year ended December 31, 2014. We accrued interest expense of $0.2 million during 2015 and $0.2 million during 2014, excluding from both years the reversal of accrued interest related to the adjustment of uncertain tax positions. If recognized, $5.0 million of unrecognized tax benefits as of December 31, 2015 and $5.5 million as of December 31, 2014 would impact our effective tax rate. Interest of $1.4 million as of December 31, 2015 and $1.7 million as of December 31, 2014 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 twelve months.

Unrecognized tax benefits, ending balance	$	7,717		$	8,583

We file U.S. federal income tax returns, as well as income tax returns in various states and several foreign jurisdictions. The years 2011 through 2014 are open for examination by the U.S. Internal Revenue Service (“IRS”), and various years are open for examination by state and foreign tax authorities. In December 2015, we were notified that the IRS will perform an audit of our amended 2011 federal income tax return. State and foreign jurisdictional statutes of limitations generally range from three to four years.

(6) DERIVATIVE FINANCIAL INSTRUMENT

In the normal course of business we are subject to risk from adverse fluctuations in foreign exchange and interest rates and commodity prices. We manage our risks for interest rate changes through use of an interest rate swap. At December 31, 2015, we had one interest rate swap outstanding, which matures in September 2019, with a notional value of $75.0 million and a pre-tax fair value loss of $1.5 million. The counterparty to this contract is a major financial institution. We are exposed to credit loss in the event of non-performance by the counterparty. We do not use derivative instruments for trading or speculative purposes and have no derivative financial instruments to reduce our exposure to fuel price fluctuations.

Our objective in managing exposure to interest rate risk is to limit the impact on earnings and cash flow. The extent to which we use such instruments is dependent on our access to these contracts in the financial markets and its success using other methods.

Our outstanding derivative financial instrument is recognized as an other long-term liability in the Consolidated Balance Sheets at fair value. The interest rate swap is accounted for as a cash flow hedging instrument. At inception, we formally designated and documented the financial instrument as a hedge of a specific underlying exposure, the risk management objective, and the manner in which effectiveness of the hedge will be assessed. We formally assess, both at inception and at each reporting period thereafter, whether the derivative financial instrument is effective in offsetting changes in cash flows of the related underlying exposure. All changes in fair value of outstanding derivatives in cash flow hedges, except any ineffective portion, are recorded in other comprehensive income until earnings are impacted by the hedged transaction. Classification of the gain or loss in the Consolidated Statements of Income upon release from comprehensive income is the same as that of the underlying exposure. Any ineffective portion of the change in fair value of the instruments is recognized immediately in earnings.

We will discontinue the use of hedge accounting prospectively when (i) the derivative instrument is no longer effective in offsetting changes in fair value or cash flows of the underlying hedged item; (ii) the derivative instrument expires, is sold, terminated, or exercised; or (iii) designating the derivative instrument as a hedge is no longer appropriate.

Should we discontinue hedge accounting because it is no longer probable that an anticipated transaction will occur in the originally expected period, or within an additional two-month period thereafter, changes to fair value accumulated in other comprehensive income are recognized immediately in earnings.

FASB ASC 815-10 requires companies to recognize the derivative instrument as an asset or a liability at fair value in the statement of financial position. Fair value of the derivative instrument is required to be measured under the FASB’s Fair Value Measurements and Disclosures guidance, which establishes a hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy). Level 1 inputs use quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. The fair value of our interest rate swap is based on Level 2 inputs.

(7) EQUITY COMPENSATION AND EMPLOYEE BENEFIT PLANS

Equity Plan

The Werner Enterprises, Inc. Amended and Restated Equity Plan (the “Equity Plan”), approved by the Company's shareholders, 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 stock and units (“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. As of December 31, 2015, there were 7,357,396 shares available for granting additional awards.

Equity compensation expense is included in salaries, wages and benefits within the Consolidated Statements of Income. As of December 31, 2015, the total unrecognized compensation cost related to non-vested equity compensation awards was approximately $9.9 million and is expected to be recognized over a weighted average period of 2.5 years. The following table summarizes the equity compensation expense and related income tax benefit recognized in the Consolidated Statements of Income (in thousands):

	Years Ended December 31,
	2015		2014		2013
Stock options:
Pre-tax compensation expense	$	30	$	116	$	84
Tax benefit	11		46		31
Stock option expense, net of tax	$	19	$	70	$	53
Restricted awards:
Pre-tax compensation expense	$	1,875	$	4,134	$	4,727
Tax benefit	722		1,622		1,831
Restricted stock expense, net of tax	$	1,153	$	2,512	$	2,896
Performance awards:
Pre-tax compensation expense	$	2,514	$	1,859	$	—
Tax benefit	968		724		—
Restricted stock expense, net of tax	$	1,546	$	1,135	$	—

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 2016.

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 become 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.

39

The following table summarizes stock option activity for the year ended December 31, 2015:

	Number of Options (in thousands)		Weighted Average Exercise Price ($)		Weighted Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value (in thousands)
Outstanding at beginning of period	248		$	18.18
Granted	—		—
Exercised	(48	)	17.46
Forfeited	(8	)	19.96
Expired	—		—
Outstanding at end of period	192		18.29		2.89	$	980
Exercisable at end of period	182		18.06		2.72	$	969

We did not grant any stock options during the years ended December 31, 2015, 2014 and 2013. The fair value of stock option grants is estimated using a Black-Scholes valuation model.

The total intrinsic value of stock options exercised was as follows (in thousands):

2015	$	655
2014	3,687
2013	896

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 84 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.

The following table summarizes restricted award activity for the year ended December 31, 2015:

	Number of Restricted Awards (in thousands)		Weighted Average Grant Date Fair Value ($)
Nonvested at beginning of period	643		$	22.92
Granted	126		26.30
Vested	(164	)	22.03
Forfeited	(160	)	22.58
Nonvested at end of period	445		24.32

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 Sheets and are adjusted to fair value each reporting period. The following table summarizes the number of restricted awards granted (in thousands) and the weighted-average assumptions used to calculate the present value of estimated future dividends:

	Years Ended December 31,
	2015			2014			2013
Number of shares granted	126			140			115
Dividends per share (quarterly amounts)	$	0.06		$	0.05		$	0.05
Risk-free interest rate	1.6		%	1.6		%	1.4		%

40

The total fair value of previously granted restricted awards vested during the years ended December 31, 2015, 2014, and 2013 was $4.5 million, $5.8 million, and $5.5 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 the 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 60 months from 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.

The following table summarizes performance award activity for the year ended December 31, 2015:

	Number of Performance Awards (in thousands)		Weighted Average Grant Date Fair Value ($)
Nonvested at beginning of period	183		$	25.06
Granted	202		28.79
Vested	(37	)	25.06
Forfeited	(90	)	27.19
Nonvested at end of period	258		27.23

The performance awards are earned based upon the level of attainment by the Company of specified performance objectives related to earnings per share for the fiscal year, as established by the Compensation Committee. The number of shares which are ultimately earned for the 2015 awards will range from 0 percent to 132 percent of the target number based on the level of attainment of the performance objectives and ranged from 0 percent to 133 percent for the 2014 awards. 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 following table summarizes the number of performance awards granted (in thousands) and the assumptions used to calculate the present value of estimated future dividends:

	Years Ended December 31,
	2015			2014
Number of shares granted	202			183
Dividends per share (quarterly amounts)	$	0.06		$	0.05
Risk-free interest rate	1.6		%	1.5		%

During the year ended December 31, 2015, the Compensation Committee determined that the 2014 fiscal year performance objectives were achieved at the target level and 182,813 shares of common stock were earned, subject to time-based vesting. The vesting date fair value of the performance awards vested during the year ended December 31, 2015 was $1.1 million. 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 the shares withheld to satisfy the minimum tax withholding obligations are 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. 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

41

contributions at a rate of 5.25% until the purchase is made. We pay the broker’s 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):

2015	$	182
2014	188
2013	210

401(k) Retirement Savings Plan

We have an Employees’ 401(k) Retirement Savings Plan (the “401(k) Plan”). Associates are eligible to participate in the 401(k) Plan if they have been continuously employed with us or one of our subsidiaries for six months or more. We match a portion of each associate’s 401(k) Plan elective deferrals. Salaries, wages and benefits expense in the accompanying Consolidated Statements of Income includes our 401(k) Plan contributions and administrative expenses, which were as follows (in thousands):

2015	$	2,041
2014	1,812
2013	1,722

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, 2015, there were 56 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. We purchased life insurance policies to fund the future liability. The aggregate market value of the life insurance policies is included in other non-current assets in the Consolidated Balance Sheets.

The accumulated benefit obligation and aggregate market value of the life insurance policies were as follows (in thousands):

	December 31,
	2015		2014
Accumulated benefit obligation	$	7,068	$	6,785
Aggregate market value	6,216		6,055

(8) COMMITMENTS AND CONTINGENCIES

We have committed to property and equipment purchases of approximately $112.0 million at December 31, 2015.

We are involved in certain claims and pending litigation 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 employments 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 events related thereto unfold.

We are involved in class action litigation in the U.S. District Court for the District of Nebraska, alleging that we owe drivers for unpaid wages under the Fair Labor Standards Act and the Nebraska Wage Payment and Collection Act and failed to pay minimum wage per hour for drivers in our student driver training program, related to short break time and sleeper berth time. The period covered by this class action suit dates back to 2008 through March 2014. In August 2015, the court denied our motion for summary judgment and granted the plaintiff's motion for summary judgment, ruling in plaintiff's favor on both theories of liability (short breaks and sleeper berth time). As a result, we accrued $2.0 million during third quarter 2015 related to the short break matter. Based on the knowledge of the facts related to the sleeper berth matter, management does not currently believe a loss is

42

probable, thus we have not accrued for the sleeper berth matter. We are currently unable to determine the possible loss or range of loss. We intend to vigorously defend the merits of these claims and to appeal any adverse verdict in this case.

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 deduction and other items. Based on the knowledge of the facts, management does not currently believe the outcome of the litigation 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 disposition cannot be determined at this time.

(9) RELATED PARTY TRANSACTIONS

The Company leases land from a trust in which the Company’s principal stockholder is the sole trustee. The annual rent payments under this lease are $1.00 per year. The Company is responsible for all real estate taxes and maintenance costs related to the property, which were $52,000 in 2015 and are recorded as expenses in the Consolidated Statements of Income. The Company has made leasehold improvements to the land totaling approximately $6.5 million for facilities used for business meetings and customer promotion.

The Company transacts business with TDR Transportes, S.A. de C.V. (“TDR”), a truckload carrier in the Republic of Mexico, for certain purchased transportation needs. The Company recorded operating revenues from TDR of approximately $4,421,000 in 2015, $4,623,000 in 2014 and $4,141,000 in 2013 related primarily to leasing revenue equipment and a terminal building. The Company recorded purchased transportation expense to TDR of approximately $477,000 in 2015, $651,000 in 2014 and $603,000 in 2013. The Company also sells used revenue equipment to this entity. These sales totaled $164,000 in 2015, $2,154,000 in 2014 and $2,275,000 in 2013, and the Company recognized net gains of $41,000 in 2015, $858,000 in 2014 and $1,449,000 in 2013. The Company had receivables from TDR, primarily related to the leases and revenue equipment sales, of $504,000 at December 31, 2015, $442,000 at December 31, 2014 and $858,000 at December 31, 2013.

(10) SEGMENT INFORMATION

We have two reportable segments – Truckload Transportation Services (“Truckload”) and Value Added Services (“VAS”).

The Truckload segment consists of two operating units, One-Way Truckload and Specialized Services, that are aggregated because they have similar economic characteristics and meet the other aggregation criteria described in the accounting guidance for segment reporting. 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; (ii) the expedited (“Expedited”) fleet provides time-sensitive truckload services utilizing driver teams; and (iii) the regional short-haul (“Regional”) fleet provides comparable truckload van service within geographic regions across the United States. Specialized Services provides truckload services dedicated to a specific customer, generally for a retail distribution center or manufacturing facility, including services for products requiring specialized trailers such as flatbed or temperature-controlled trailers. Revenues for the Truckload segment include a small amount of non-trucking revenues which consist primarily of the portion of shipments delivered to or from Mexico where we utilize a third-party capacity provider.

The VAS segment generates the majority of our non-trucking revenues through four operating units that provide non-trucking services to our customers. These four VAS operating units are as follows: (i) truck brokerage (“Brokerage”) uses contracted carriers to complete customer shipments; (ii) freight management (“Freight Management”) offers a full range of single-source logistics management services and solutions; (iii) 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.

We generate other revenues from our driver training schools and from transportation-related activities such as third-party equipment maintenance, 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. We do not prepare separate balance sheets by segment and, as a result, assets are not separately identifiable by segment. 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, 2015, 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

45

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, 2015. 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, 2015.

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.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

Werner Enterprises, Inc.:

We have audited Werner Enterprises, Inc.’s internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Werner Enterprises, Inc.’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, 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.

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

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

In our opinion, Werner Enterprises, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015 based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Werner Enterprises, Inc. and subsidiaries as of December 31, 2015 and 2014, and the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2015, and our report dated February 26, 2016, expressed an unqualified opinion on those consolidated financial statements.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Business: Werner Enterprises, Inc. (the “Company”) is a truckload transportation and logistics company 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. For the year ended December 31, 2015, our ten largest customers comprised 45% of our revenues. For the years ended December 31, 2014 and 2013, our ten largest customers comprised 41% and 40%, respectively, of our revenues. No single customer generated more than 10% of the Company’s total revenues in 2015, 2014, and 2013.

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 useful lives and salvage values of property and equipment, accrued liabilities for insurance and claims, estimates for incomes 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, and changes in such accounts are reported as a financing activity in the Consolidated Statements of Cash Flows.

Trade Accounts Receivable: We record trade accounts receivable at the invoiced amounts, net of an allowance for doubtful accounts. The allowance for doubtful accounts is our estimate of the amount of probable credit losses and revenue adjustments in our existing accounts receivable. 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 or market 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:

	Lives	Salvage Values
Building and improvements	30 years	0%
Tractors	80 months	0%
Trailers	12 years	$1,000
Service and other equipment	3-10 years	0%

Long-Lived Assets: 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. 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 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 Statements of 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 insurance and claims accruals are based upon individual case estimates (including negative development) and estimates of incurred-but-not-reported losses using loss development factors based upon past experience. Actual costs related to insurance and claims have not differed materially from estimated accrued amounts for all years presented. An actuary reviews our undiscounted self-insurance reserves for bodily injury and property damage claims and workers’ compensation claims at year-end.

For the years ended December 31, 2015, 2014, and 2013 our self-insured retention (“SIR”) and deductible amount for liability claims is $2.0 million plus administrative expenses, for each occurrence involving bodily injury or property damage. We are also responsible for varying annual aggregate amounts of liability for claims in excess of the SIR/deductible. Liability claims in excess of these aggregates are covered under premium-based policies (issued by insurance companies) to coverage levels that our management considers adequate. 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 million per claim, with premium-based insurance coverage for claims exceeding this amount. We also maintain a $29.8 million bond for the State of Nebraska and a $6.9 million bond for our workers’ compensation insurance carrier.

Under these insurance arrangements, we maintained $31.0 million in letters of credit as of December 31, 2015.

Revenue Recognition: The Consolidated Statements of Income reflect recognition of operating revenues (including fuel surcharge revenues) and related direct costs when the shipment is delivered. 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) 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/or (iv) have credit risk 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 revenues net of those expenses related to third-party providers.

Derivative Financial Instrument: We manage our interest rate risk through an interest rate swap. The derivative financial instrument is recognized in the Consolidated Balance Sheets at fair value. The effect on earnings from recognizing the fair value of this derivative financial instrument depends on its intended use, its hedge designation, and its effectiveness in offsetting changes in the fair value of the exposure it is hedging. Changes in the fair value of the instrument designated to reduce or eliminate adverse fluctuations in the fair values of recognized assets and liabilities and unrecognized firm commitments are reported currently in earnings along with changes in the fair values of the hedged items. Changes in the effective portion of the fair value of the instrument used to reduce or eliminate adverse fluctuations in cash flows of anticipated or forecasted transactions is reported in equity as a component of accumulated other comprehensive income (loss), net of income tax effects. Amounts in accumulated other comprehensive income (loss) are reclassified to earnings when the related hedged items affect earnings or the anticipated transactions are no longer probable. Amounts reported in earnings are classified consistent with the item being hedged.

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 Sheets and as a separate component of comprehensive income in the Consolidated Statements of Comprehensive Income.

Income Taxes: We use the asset and liability method in accounting for income taxes. Under this method, deferred 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 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.

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).

	Years Ended December 31,
	2015		2014		2013
Net income	$	123,714	$	98,650	$	86,785
Weighted average common shares outstanding	71,957		72,122		72,866
Dilutive effect of stock-based awards	599		616		562
Shares used in computing diluted earnings per share	72,556		72,738		73,428
Basic earnings per share	$	1.72	$	1.37	$	1.19
Diluted earnings per share	$	1.71	$	1.36	$	1.18

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, restricted stock units 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 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.

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, 2015 and 2014, comprehensive income consists of net income, foreign currency translation adjustments and change in fair value of interest rate swap. For the year ended December 31, 2013, comprehensive income consists of net income and foreign currency translation adjustments.

New Accounting Pronouncements Adopted: We did not adopt any new accounting standards during 2015.

Accounting Standards Updates Not Yet Effective: On May 28, 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In July 2015, the FASB voted to approve a one-year deferral of the effective date of the new revenue recognition standard and to permit early adoption but no earlier than the original effective date (annual periods beginning after December 15, 2016); such decisions were documented in the FASB's ASU No. 2015-14 “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date.” As a result of the deferral, the new standard will become effective for us beginning January 1, 2018, unless we choose to adopt early on January 1, 2017. The standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures and have not yet selected a transition method.

In April 2015, the FASB issued ASU No. 2015-3, “Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs,” which requires debt issuance costs to be recorded as a direct reduction of the debt liability on the balance sheet rather than as an asset. The provisions of this update are effective as of January 1, 2016, and are not expected to have a material effect on our consolidated financial position, results of operations or cash flows.

In July 2015, the FASB issued ASU No. 2015-11, “Inventory: Simplifying the Measurement of Inventory,” which requires inventory to be recorded at the lower of cost and net realizable value. The provisions of this update are effective as of January 1, 2017, and are not expected to have a material effect on our consolidated financial position, results of operations or cash flows.

In November 2015, the FASB issued ASU No. 2015-17, “Income Taxes: Balance Sheet Classification of Deferred Taxes,” which requires presentation of deferred tax assets and liabilities as non-current in the balance sheet. The provisions of this update are effective as of January 1, 2017, and early adoption is permitted as of the beginning of an interim or annual reporting period. The amendments in the update are not expected to have a material effect on our consolidated financial position, results from operations or cash flows.

Other ASUs not identified above and which are not effective until after December 31, 2015 are not expected to have a material effect on our consolidated financial position, results of operations or cash flows.

CREDIT FACILITIES

As of December 31, 2015, we had unsecured committed credit facilities with three banks as well as a term commitment with one of these banks. We had with Wells Fargo Bank, N.A., a $100.0 million credit facility which will expire on July 12, 2020, and a $75.0 million term commitment with principal due and payable on September 15, 2019. On July 13, 2015, we amended our existing credit agreement, dated June 1, 2012, as previously amended, with Wells Fargo Bank, N.A. This amendment lowered the maximum principal amount of the unsecured line of credit to $100.0 million from $175.0 million and extended the term of the credit agreement to July 12, 2020 from May 31, 2016. Also on July 13, 2015, we entered into a new credit agreement with U.S. Bank, N.A. The new credit agreement is an unsecured line of credit of $75.0 million and expires on July 13, 2020. We also had a $75.0 million credit facility with BMO Harris Bank, N.A., which will expire on March 5, 2020. On March 5, 2015, we replaced our existing $75.0 million credit agreement with BMO Harris Bank, N.A., with a new credit agreement. The new BMO Harris Bank, N.A., agreement includes a $75.0 million credit facility which will expire on March 5, 2020. Borrowings under these credit facilities and term note bear variable interest (0.9305% at December 31, 2015) based on the London Interbank Offered Rate (“LIBOR”), with interest on the term note effectively fixed at 2.5% with an interest rate swap agreement.

As of December 31, 2015 and 2014, our outstanding debt totaled $75.0 million. The $325.0 million of credit available under these facilities is further reduced by $31.0 million in stand-by letters of credit under which we are obligated. Each of the debt agreements includes, among other things, financial covenants requiring us (i) not to exceed a maximum ratio of total debt to total capitalization and/or (ii) not to exceed a maximum ratio of total funded debt to earnings before interest, income taxes, depreciation and amortization (as such terms are defined in each credit facility). At December 31, 2015, we were in compliance with these covenants.

At December 31, 2015, the aggregate future maturities of long-term debt by year are as follows (in thousands):

2016	$	—
2017	—

We have not recorded a valuation allowance because we believe that all deferred tax assets are more likely than not to be realized as a result of our historical profitability, future taxable income and reversal of deferred tax liabilities.

We recognized a $551 thousand decrease in the net liability for unrecognized tax benefits for the year ended December 31, 2015 and a $37 thousand decrease for the year ended December 31, 2014. We accrued interest expense of $0.2 million during 2015 and $0.2 million during 2014, excluding from both years the reversal of accrued interest related to the adjustment of uncertain tax positions. If recognized, $5.0 million of unrecognized tax benefits as of December 31, 2015 and $5.5 million as of December 31, 2014 would impact our effective tax rate. Interest of $1.4 million as of December 31, 2015 and $1.7 million as of December 31, 2014 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 twelve months.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative financial instruments

DERIVATIVE FINANCIAL INSTRUMENT

In the normal course of business we are subject to risk from adverse fluctuations in foreign exchange and interest rates and commodity prices. We manage our risks for interest rate changes through use of an interest rate swap. At December 31, 2015, we had one interest rate swap outstanding, which matures in September 2019, with a notional value of $75.0 million and a pre-tax fair value loss of $1.5 million. The counterparty to this contract is a major financial institution. We are exposed to credit loss in the event of non-performance by the counterparty. We do not use derivative instruments for trading or speculative purposes and have no derivative financial instruments to reduce our exposure to fuel price fluctuations.

Our objective in managing exposure to interest rate risk is to limit the impact on earnings and cash flow. The extent to which we use such instruments is dependent on our access to these contracts in the financial markets and its success using other methods.

Our outstanding derivative financial instrument is recognized as an other long-term liability in the Consolidated Balance Sheets at fair value. The interest rate swap is accounted for as a cash flow hedging instrument. At inception, we formally designated and documented the financial instrument as a hedge of a specific underlying exposure, the risk management objective, and the manner in which effectiveness of the hedge will be assessed. We formally assess, both at inception and at each reporting period thereafter, whether the derivative financial instrument is effective in offsetting changes in cash flows of the related underlying exposure. All changes in fair value of outstanding derivatives in cash flow hedges, except any ineffective portion, are recorded in other comprehensive income until earnings are impacted by the hedged transaction. Classification of the gain or loss in the Consolidated Statements of Income upon release from comprehensive income is the same as that of the underlying exposure. Any ineffective portion of the change in fair value of the instruments is recognized immediately in earnings.

We will discontinue the use of hedge accounting prospectively when (i) the derivative instrument is no longer effective in offsetting changes in fair value or cash flows of the underlying hedged item; (ii) the derivative instrument expires, is sold, terminated, or exercised; or (iii) designating the derivative instrument as a hedge is no longer appropriate.

Should we discontinue hedge accounting because it is no longer probable that an anticipated transaction will occur in the originally expected period, or within an additional two-month period thereafter, changes to fair value accumulated in other comprehensive income are recognized immediately in earnings.

FASB ASC 815-10 requires companies to recognize the derivative instrument as an asset or a liability at fair value in the statement of financial position. Fair value of the derivative instrument is required to be measured under the FASB’s Fair Value Measurements and Disclosures guidance, which establishes a hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy). Level 1 inputs use quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. The fair value of our interest rate swap is based on Level 2 inputs.

Equity Compensation and Employee Benefit Plans

EQUITY COMPENSATION AND EMPLOYEE BENEFIT PLANS

Equity Plan

The Werner Enterprises, Inc. Amended and Restated Equity Plan (the “Equity Plan”), approved by the Company's shareholders, 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 stock and units (“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. As of December 31, 2015, there were 7,357,396 shares available for granting additional awards.

Equity compensation expense is included in salaries, wages and benefits within the Consolidated Statements of Income. As of December 31, 2015, the total unrecognized compensation cost related to non-vested equity compensation awards was approximately $9.9 million and is expected to be recognized over a weighted average period of 2.5 years. The following table summarizes the equity compensation expense and related income tax benefit recognized in the Consolidated Statements of Income (in thousands):

	Years Ended December 31,
	2015		2014		2013

Tax benefit	968		724		—
Restricted stock expense, net of tax	$	1,546	$	1,135	$	—

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 2016.

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 become 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.

The following table summarizes stock option activity for the year ended December 31, 2015:

	Number of Options (in thousands)		Weighted Average Exercise Price ($)		Weighted Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value (in thousands)
Outstanding at beginning of period	248		$	18.18

Outstanding at end of period	192		18.29		2.89	$	980
Exercisable at end of period	182		18.06		2.72	$	969

We did not grant any stock options during the years ended December 31, 2015, 2014 and 2013. The fair value of stock option grants is estimated using a Black-Scholes valuation model.

The total intrinsic value of stock options exercised was as follows (in thousands):

2015	$	655
2014	3,687
2013	896

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 84 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.

The following table summarizes restricted award activity for the year ended December 31, 2015:

	Number of Restricted Awards (in thousands)		Weighted Average Grant Date Fair Value ($)
Nonvested at beginning of period	643		$	22.92
Granted	126		26.30
Vested	(164	)	22.03
Forfeited	(160	)	22.58
Nonvested at end of period	445		24.32

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 Sheets and are adjusted to fair value each reporting period. The following table summarizes the number of restricted awards granted (in thousands) and the weighted-average assumptions used to calculate the present value of estimated future dividends:

	Years Ended December 31,
	2015			2014			2013
Number of shares granted	126			140			115
Dividends per share (quarterly amounts)	$	0.06		$	0.05		$	0.05
Risk-free interest rate	1.6		%	1.6		%	1.4		%

The total fair value of previously granted restricted awards vested during the years ended December 31, 2015, 2014, and 2013 was $4.5 million, $5.8 million, and $5.5 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 the 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 60 months from 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.

The following table summarizes performance award activity for the year ended December 31, 2015:

	Number of Performance Awards (in thousands)		Weighted Average Grant Date Fair Value ($)
Nonvested at beginning of period	183		$	25.06
Granted	202		28.79
Vested	(37	)	25.06
Forfeited	(90	)	27.19
Nonvested at end of period	258		27.23

The performance awards are earned based upon the level of attainment by the Company of specified performance objectives related to earnings per share for the fiscal year, as established by the Compensation Committee. The number of shares which are ultimately earned for the 2015 awards will range from 0 percent to 132 percent of the target number based on the level of attainment of the performance objectives and ranged from 0 percent to 133 percent for the 2014 awards. 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 following table summarizes the number of performance awards granted (in thousands) and the assumptions used to calculate the present value of estimated future dividends:

	Years Ended December 31,
	2015			2014
Number of shares granted	202			183
Dividends per share (quarterly amounts)	$	0.06		$	0.05
Risk-free interest rate	1.6		%	1.5		%

During the year ended December 31, 2015, the Compensation Committee determined that the 2014 fiscal year performance objectives were achieved at the target level and 182,813 shares of common stock were earned, subject to time-based vesting. The vesting date fair value of the performance awards vested during the year ended December 31, 2015 was $1.1 million. 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 the shares withheld to satisfy the minimum tax withholding obligations are 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. 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’s 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):

2015	$	182
2014	188
2013	210

401(k) Retirement Savings Plan

We have an Employees’ 401(k) Retirement Savings Plan (the “401(k) Plan”). Associates are eligible to participate in the 401(k) Plan if they have been continuously employed with us or one of our subsidiaries for six months or more. We match a portion of each associate’s 401(k) Plan elective deferrals. Salaries, wages and benefits expense in the accompanying Consolidated Statements of Income includes our 401(k) Plan contributions and administrative expenses, which were as follows (in thousands):

2015	$	2,041
2014	1,812
2013	1,722

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, 2015, there were 56 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. We purchased life insurance policies to fund the future liability. The aggregate market value of the life insurance policies is included in other non-current assets in the Consolidated Balance Sheets.

The accumulated benefit obligation and aggregate market value of the life insurance policies were as follows (in thousands):

Commitments and Contingencies

COMMITMENTS AND CONTINGENCIES

We have committed to property and equipment purchases of approximately $112.0 million at December 31, 2015.

We are involved in certain claims and pending litigation 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 employments 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 events related thereto unfold.

We are involved in class action litigation in the U.S. District Court for the District of Nebraska, alleging that we owe drivers for unpaid wages under the Fair Labor Standards Act and the Nebraska Wage Payment and Collection Act and failed to pay minimum wage per hour for drivers in our student driver training program, related to short break time and sleeper berth time. The period covered by this class action suit dates back to 2008 through March 2014. In August 2015, the court denied our motion for summary judgment and granted the plaintiff's motion for summary judgment, ruling in plaintiff's favor on both theories of liability (short breaks and sleeper berth time). As a result, we accrued $2.0 million during third quarter 2015 related to the short break matter. Based on the knowledge of the facts related to the sleeper berth matter, management does not currently believe a loss is probable, thus we have not accrued for the sleeper berth matter. We are currently unable to determine the possible loss or range of loss. We intend to vigorously defend the merits of these claims and to appeal any adverse verdict in this case.

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 deduction and other items. Based on the knowledge of the facts, management does not currently believe the outcome of the litigation 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 disposition cannot be determined at this time.

Segment Reporting [Abstract]

Segment Information

SEGMENT INFORMATION

We have two reportable segments – Truckload Transportation Services (“Truckload”) and Value Added Services (“VAS”).

The Truckload segment consists of two operating units, One-Way Truckload and Specialized Services, that are aggregated because they have similar economic characteristics and meet the other aggregation criteria described in the accounting guidance for segment reporting. 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; (ii) the expedited (“Expedited”) fleet provides time-sensitive truckload services utilizing driver teams; and (iii) the regional short-haul (“Regional”) fleet provides comparable truckload van service within geographic regions across the United States. Specialized Services provides truckload services dedicated to a specific customer, generally for a retail distribution center or manufacturing facility, including services for products requiring specialized trailers such as flatbed or temperature-controlled trailers. Revenues for the Truckload segment include a small amount of non-trucking revenues which consist primarily of the portion of shipments delivered to or from Mexico where we utilize a third-party capacity provider.

The VAS segment generates the majority of our non-trucking revenues through four operating units that provide non-trucking services to our customers. These four VAS operating units are as follows: (i) truck brokerage (“Brokerage”) uses contracted carriers to complete customer shipments; (ii) freight management (“Freight Management”) offers a full range of single-source logistics management services and solutions; (iii) 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.

We generate other revenues from our driver training schools and from transportation-related activities such as third-party equipment maintenance, 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. We do not prepare separate balance sheets by segment and, as a result, assets are not separately identifiable by segment. Inter-segment eliminations in the table below represent transactions between reporting segments that are eliminated in consolidation.

The following table summarizes our segment information (in thousands):

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2015

Accounting Policies [Abstract]

Nature of Business

Nature of Business: Werner Enterprises, Inc. (the “Company”) is a truckload transportation and logistics company 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. For the year ended December 31, 2015, our ten largest customers comprised 45% of our revenues. For the years ended December 31, 2014 and 2013, our ten largest customers comprised 41% and 40%, respectively, of our revenues. No single customer generated more than 10% of the Company’s total revenues in 2015, 2014, and 2013.

Principles of Consolidation

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

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 useful lives and salvage values of property and equipment, accrued liabilities for insurance and claims, estimates for incomes taxes and the allowance for doubtful accounts. Actual results could differ from those estimates.

Cash And Cash Equivalents

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, and changes in such accounts are reported as a financing activity in the Consolidated Statements of Cash Flows.

Trade Accounts Receivable

Trade Accounts Receivable: We record trade accounts receivable at the invoiced amounts, net of an allowance for doubtful accounts. The allowance for doubtful accounts is our estimate of the amount of probable credit losses and revenue adjustments in our existing accounts receivable. 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: Inventories and supplies are stated at the lower of average cost or market 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

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:

	Lives	Salvage Values
Building and improvements	30 years	0%
Tractors	80 months	0%
Trailers	12 years	$1,000
Service and other equipment	3-10 years	0%

Long-Lived Assets

Long-Lived Assets: 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. 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: Insurance and claims accruals (both current and non-current) reflect the estimated cost (including estimated loss development 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 Statements of 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 insurance and claims accruals are based upon individual case estimates (including negative development) and estimates of incurred-but-not-reported losses using loss development factors based upon past experience. Actual costs related to insurance and claims have not differed materially from estimated accrued amounts for all years presented. An actuary reviews our undiscounted self-insurance reserves for bodily injury and property damage claims and workers’ compensation claims at year-end.

For the years ended December 31, 2015, 2014, and 2013 our self-insured retention (“SIR”) and deductible amount for liability claims is $2.0 million plus administrative expenses, for each occurrence involving bodily injury or property damage. We are also responsible for varying annual aggregate amounts of liability for claims in excess of the SIR/deductible. Liability claims in excess of these aggregates are covered under premium-based policies (issued by insurance companies) to coverage levels that our management considers adequate. 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 million per claim, with premium-based insurance coverage for claims exceeding this amount. We also maintain a $29.8 million bond for the State of Nebraska and a $6.9 million bond for our workers’ compensation insurance carrier.

Under these insurance arrangements, we maintained $31.0 million in letters of credit as of December 31, 2015.

Revenue Recognition

Revenue Recognition: The Consolidated Statements of Income reflect recognition of operating revenues (including fuel surcharge revenues) and related direct costs when the shipment is delivered. 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) 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/or (iv) have credit risk 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 revenues net of those expenses related to third-party providers.

Derivative Financial Instrument

Derivative Financial Instrument: We manage our interest rate risk through an interest rate swap. The derivative financial instrument is recognized in the Consolidated Balance Sheets at fair value. The effect on earnings from recognizing the fair value of this derivative financial instrument depends on its intended use, its hedge designation, and its effectiveness in offsetting changes in the fair value of the exposure it is hedging. Changes in the fair value of the instrument designated to reduce or eliminate adverse fluctuations in the fair values of recognized assets and liabilities and unrecognized firm commitments are reported currently in earnings along with changes in the fair values of the hedged items. Changes in the effective portion of the fair value of the instrument used to reduce or eliminate adverse fluctuations in cash flows of anticipated or forecasted transactions is reported in equity as a component of accumulated other comprehensive income (loss), net of income tax effects. Amounts in accumulated other comprehensive income (loss) are reclassified to earnings when the related hedged items affect earnings or the anticipated transactions are no longer probable. Amounts reported in earnings are classified consistent with the item being hedged.

Foreign Currency Translation

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 Sheets and as a separate component of comprehensive income in the Consolidated Statements of Comprehensive Income.

Income Taxes

Income Taxes: We use the asset and liability method in accounting for income taxes. Under this method, deferred 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 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.

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

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).

	Years Ended December 31,
	2015		2014		2013
Net income	$	123,714	$	98,650	$	86,785
Weighted average common shares outstanding	71,957		72,122		72,866
Dilutive effect of stock-based awards	599		616		562
Shares used in computing diluted earnings per share	72,556		72,738		73,428
Basic earnings per share	$	1.72	$	1.37	$	1.19
Diluted earnings per share	$	1.71	$	1.36	$	1.18

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

Equity Compensation: We have an equity compensation plan that provides for grants of non-qualified stock options, restricted stock, restricted stock units 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 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.

Comprehensive Income

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, 2015 and 2014, comprehensive income consists of net income, foreign currency translation adjustments and change in fair value of interest rate swap. For the year ended December 31, 2013, comprehensive income consists of net income and foreign currency translation adjustments.

New Accounting Pronouncements Adopted

New Accounting Pronouncements Adopted: We did not adopt any new accounting standards during 2015.

Accounting Standards Updates Not Yet Effective

Accounting Standards Updates Not Yet Effective: On May 28, 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In July 2015, the FASB voted to approve a one-year deferral of the effective date of the new revenue recognition standard and to permit early adoption but no earlier than the original effective date (annual periods beginning after December 15, 2016); such decisions were documented in the FASB's ASU No. 2015-14 “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date.” As a result of the deferral, the new standard will become effective for us beginning January 1, 2018, unless we choose to adopt early on January 1, 2017. The standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures and have not yet selected a transition method.

In April 2015, the FASB issued ASU No. 2015-3, “Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs,” which requires debt issuance costs to be recorded as a direct reduction of the debt liability on the balance sheet rather than as an asset. The provisions of this update are effective as of January 1, 2016, and are not expected to have a material effect on our consolidated financial position, results of operations or cash flows.

In July 2015, the FASB issued ASU No. 2015-11, “Inventory: Simplifying the Measurement of Inventory,” which requires inventory to be recorded at the lower of cost and net realizable value. The provisions of this update are effective as of January 1, 2017, and are not expected to have a material effect on our consolidated financial position, results of operations or cash flows.

In November 2015, the FASB issued ASU No. 2015-17, “Income Taxes: Balance Sheet Classification of Deferred Taxes,” which requires presentation of deferred tax assets and liabilities as non-current in the balance sheet. The provisions of this update are effective as of January 1, 2017, and early adoption is permitted as of the beginning of an interim or annual reporting period. The amendments in the update are not expected to have a material effect on our consolidated financial position, results from operations or cash flows.

Other ASUs not identified above and which are not effective until after December 31, 2015 are not expected to have a material effect on our consolidated financial position, results of operations or cash flows.
