Asset-Based Segment

Our Asset-Based segment provides LTL services through ABF Freight’s motor carrier operations. Asset-Based revenues which totaled $2.0 billion for the year ended December 31, 2017 and $1.9 billion for each of the years ended December 31, 2016 and 2015, accounted for approximately 70%69% of our total revenues before other revenues and intercompany eliminations in 2017 and 2016 and approximately 71% in 2015.2018. For the year ended December 31, 2017,2018, no single customer accounted for more than 6%4% of revenues in the Asset-Based segment, and the segment’s 10 largest customers, on a combined basis, accounted for approximately 15%13% of its revenues. Note M to our consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K contains additional segment financial information, including revenues and operating income for the years ended December 31, 2018, 2017, 2016, and 2015.2016.

Our Asset-Based carrier, ABF Freight, has been in continuous service since 1923. ABF Freight System, Inc. is the successor to Arkansas Motor Freight, a business originally organized in 1935 which was the successor to a local transfer and storage carrier that was originally organized in 1923. ABF Freight expanded operations through several strategic acquisitions and organic growth and is now one of the largest LTL motor carriers in North America, providing direct service to

The 2018 ABF NMFA and the related supplemental agreements provide for continued contributions to variousmultiemployer pension plans frozen at the current rates for each fund, continuation of existing health coverage, and annual contribution rate increases to multiemployer health welfare, and pensionwelfare plans maintained for the benefit of our Asset-BasedABF's employees who are members of the IBT. The estimated net effect ofUnder the November 3, 2013 wage rate reduction and2018 ABF NMFA, the benefit rate increase which was applied retroactively to August 1, 2013 was an initial reduction of approximately 4% to the combined total contractual wage and benefit rate underbenefits costs, including the ABF NMFA. Following the initial reduction, the combined contractual wageratification bonuses and benefit contribution rate under the ABF NMFA increasedvacation restoration, are estimated to increase approximately 2.5%2.0% on a compounded annual basis throughoutthrough the end of the agreement. Profit-sharing bonuses based on the Asset-Based segment’s annual operating ratios for any full calendar year under the contract period, which extends through March 31, 2018.would represent an additional increase in costs under the 2018 ABF NMFA.

Amendments to the Employee Retirement Income Security Act of 1974 (“ERISA”), pursuant to the Multiemployer Pension Plan Amendments Act of 1980 (the “MPPA Act”), substantially expanded the potential liabilities of employers who participate in multiemployer pension plans. Under ERISA, as amended by the MPPA Act, an employer who contributes to a multiemployer pension plan and the members of such employer’s controlled group are jointly and severally

ArcBest Segment

As previously discussed in “Strategy” within this Business section, our ArcBest segment originated with the formation of the ABF Logistics segment in July 2013, when we strategically aligned the sales and operations functions of our organicorganically-developed logistics businesses. The ArcBest segment now also includes the ground expedite services of the Panther Premium Logistics brand; do-it-yourselfhousehold goods moving services under the U-Pack brand, for which the majority of the moves are provided with the  assured capacity of our Asset-Based operations; and the acquired operations of Smart Lines, Bear, and LDS. Under our enhanced market approach to offer customers a single source of end-to-end logistics, the service offerings of the ArcBest segment continue to become more integrated. Management’s operating decisions have become more focused on the ArcBest segment’s combined operations, rather than individual service offerings within the segment’s operations. The ArcBest segment offers the following solutions:

Truckload and Truckload-Dedicated

Our Truckload and Truckload-Dedicated services provide third-party transportation brokerage by sourcing a variety of capacity solutions, including dry van over the road, temperature-controlled and refrigerated, flatbed, intermodal or container shipping, and specialized equipment, coupled with strong technology and carrier- and customer-based Web tools. We offer a growing network of over 18,000 vetted service providers, with services to 50 states, Canada, and Mexico. Additional value is created for customers through seamless access to the ABF Freight network.

Expedite

Through the Panther Premium Logistics brand, we offer Expediteexpedite freight transportation services to commercial and government customers and we offer premium logistics services that involve the rapid deployment of highly specialized equipment to meet extremely specific linehaul requirements, such as temperature control, hazardous materials, geofencing (routing a shipment across a mandatory, defined route with satellite monitoring and automated alerts concerning any deviation from the route), specialized government cargo, security services, and life sciences. Through its premium logistics service,these services, ArcBest solves the toughest shipping and logistics challenges that customers face through a global network of owner operators and contract carriers.

Substantially all of the network capacity for our Expediteexpedite operations is provided by third-party carriers, including owner operators, ground linehaul providers, cartage agents, and other transportation asset providers, which are selected based on their ability to serve our customers effectively with respect to price, technology capabilities, geographic coverage, and quality of service. Third-party owned vehicles are driven by independent contract drivers and by drivers engaged directly by independent owners of multiple pieces of equipment, commonly referred to as fleet owners. Our Expediteexpedite operations own a fleet of trailers, the communication devices used by its owner operators, and certain highly specialized equipment, primarily temperature-controlled and temperature-validated trailers, to meet the service requirements of certain customers.

Truckload and Truckload-Dedicated

Our truckload and truckload-dedicated services provide third-party transportation brokerage by sourcing a variety of capacity solutions, including dry van over the road, temperature-controlled and refrigerated, flatbed, intermodal or container shipping, and specialized equipment, coupled with strong technology and carrier- and customer-based Web tools. We offer a growing network of 26,000 vetted service providers, with services to 50 states, Canada, and Mexico. Additional value is created for customers through seamless access to the ABF Freight network.

International

Our International services provide international ocean and air shipping solutions by partnering with ocean shipping lines and air freight carriers worldwide. As a non-vessel operating common carrier, (NVOCC), we provide less-than-container load (LCL) and full-containerfull‑container load (FCL) service, offering ocean transport to approximately 90% of the total ocean international market to and from the United States.

Managed Transportation

We also provide freight transportation and management services for customers. ArcBest seeks to offer value through identifying specific challenges relating to customers’ supply chain needs and providing customized solutions utilizing technology, both internally to manage its business processes and externally to provide shipment and inventory visibility to its customers. Additional value is created for customers through seamless access to the ABF Freight network, the Panther fleet, and other ArcBest capacity sources, offering strategic supply chain solutions with unique access to assured capacity.

Moving

Our Movingmoving services offer flexibility and convenience toin the way people move through targeted service offerings for the “do-it-yourself” consumer and corporate account employee relocations. We offer these targeted services at competitive prices that reflect the additional value customers find in Moving’sour convenient, reliable moving service offerings. Industry leading technology, customer-friendly interfaces, and supply chain solutions are combined to provide a wide range of options customized to meet unique customer needs.

Other Logistics Services

We also provide other services to meet our customers’ logistics needs, such as final mile, time critical, product launch, warehousing and distribution, retail logistics, supply chain optimization, and trade show shipping services.

Effective August 1, 2017, we began applying space-based pricing on shipments subject to LTL tariffs to better reflect freight shipping trends that have evolved over the last several years. These trends include the overall growth and ongoing profile shift of bulkier shipments across the entire supply chain, the acceleration in e-commerce, and the unique requirements of many shipping and logistics solutions. An increasing percentage of freight is taking up more space in trailers without a corresponding increase in weight. Space-based pricing involves the use of freight dimensions (length, width, and height) to determine applicable cubic minimum charges (“CMC”) that will supplement weight-based metrics when appropriate. Traditional LTL pricing is generally weight-based, while our linehaul costs are generally space-based (i.e., costs are impacted by the volume of space required for each shipment). We believe space-based pricing better aligns our pricing mechanisms with the metrics which affect our resources and, therefore, our costs to ship freight.provide logistics services. We seek to provide logistics solutions to our customers’ businessbusinesses and the unique shipment characteristics of their various products and commodities, and we believe that we are particularly experienced in handling complicated freight. The CMC is an additional pricing mechanism to better capture the value we provide in transporting these shipments.

Our Asset-Based and certain operations within our ArcBest segment assess a fuel surcharge based on the index of national on-highway average diesel fuel prices published weekly by the U.S. Department of Energy. While the fuel surcharge is one of several components in our overall rate structure, the actual rate paid by customers is governed by market forces and the overall value of services provided to the customer.

Industry Factors

According to management’s estimates and market studies by Armstrong & Associates, Inc. and the U.S. Department of Commerce, the total market potential in the industry segments we serve is approximately $286$305 billion, with $38$41 billion of potential revenue in the LTL market segment, $205$221 billion potential in the markets served by our ArcBest segment, and $43 billion in the maintenance and repair market served by our FleetNet segment. The LTL industry has significant barriers to entry and is highly competitive, as previously discussed in “Asset-Based Segment” within this Business section. Based on 20172018 revenues, our Asset-Light operations represents a minor portion of the total market, which evidences the significant growth opportunity for us in the outsourced logistics market. More sophisticated supply chain practices are required as supply chains expand and become more complex, product and service needs continue to evolve, and companies look for solutions to their logistics challenges as well as for lower cost supply chain alternatives. Regulation in the transportation industry, as further discussed below, will continue to impair the competitiveness of smaller carriers in the logistics market, which may lead to tighter capacity or consolidation within certain sectors of the logistics market. In addition, disruptions from unexpected events such as natural disasters have resulted in further utilization of expedited shipping and premium logistics services and have caused companies to focus on risk management of their supply chains.

Various federal and state agencies exercise broad regulatory powers over the transportation industry, generally governing such activities as operations of and authorization to engage in motor carrier freight transportation, operations of non-vessel-operatingnon‑vessel‑operating common carriers, operations of ocean freight forwarders and ocean transportation intermediaries, safety, contract compliance, insurance and bonding requirements, tariff and trade policies, customs, import and export, employment practices, licensing and registration, taxation, environmental matters, data privacy and security, and financial reporting. The trucking industry faces rising costs, including costs of compliance with government regulations on safety, equipment design and maintenance, driver utilization, and fuel economy, and rising costs in certain non-industry specific areas, including health care and retirement benefits.

We are subject to various laws, rules, and regulations and are required to obtain and maintain various licenses and permits, some of which are difficult to obtain. The ArcBest segment’s network of third-party contract carriers must also comply with industry regulations, including the mandate of the Federal Motor Carrier Safety Administration (the “FMCSA”) for interstate commercial trucks to have electronic logging devices (“ELDs”) installed to monitor compliance with hours-of-servicehours‑of‑service regulations, became effective in December 2017. ELDs are fully operational on ABF Freight’s city and road tractors for electronic logging and the electronic capture of drivers’ hours of service for reporting. The ArcBest segment’s network of third-party contract carriers must also comply with industry regulations, including the ELD mandate and other regulations such as the safety and fitness regulations of the Department of Transportation (the “DOT”), including requirements related to drug and alcohol testing and hours of service. Any future modifications to these rules and other regulations impacting the transportation industry may impact our operating practices and costs.

Seasonality

Our operations are impacted by seasonal fluctuations which are described in “Seasonality” within Management’s Discussionaffect tonnage, shipment levels, and Analysisdemand for our services and, consequently, revenues and operating results. Freight shipments and operating costs of Financial Conditionour Asset-Based and ResultsArcBest segments can be adversely affected by inclement weather conditions. The second and third calendar quarters of Operations included in Part II, Item 7 of this Annual Report on Form 10-K.

each year

usually have the highest tonnage levels, while the first quarter generally has the lowest, although other factors, including the state of the U.S. and global economies, may influence quarterly freight tonnage levels.

Shipments of the ArcBest segment may decline during winter months because of post-holiday slowdowns, but expedite shipments can be subject to short-term increases depending on the impact of weather disruptions to customers’ supply chains. Plant shutdowns during summer months may affect shipments for automotive and manufacturing customers of the ArcBest segment, but severe weather events can result in higher demand for expedite services. Moving services of the ArcBest segment are impacted by seasonal fluctuations, generally resulting in higher business levels in the second and third quarters as the demand for moving services is typically stronger in the summer months.

Emergency roadside service events of the FleetNet segment are favorably impacted by extreme weather conditions that affect commercial vehicle operations, and the segment’s results of operations will be influenced by seasonal variations in service event volume.

Technology

Our advancements in technology are important to customer service and provide a competitive advantage. We continue to make investments in technology and innovations, including investments for improving the delivery of services to our customers and investments in comprehensive transportation and logistics services across ArcBest. The majority of the applications of information technology we use have been developed internally by our ArcBest Technologies subsidiary and tailored specifically for customer or internal business processing needs. ArcBest Technologies has made technology investments in a variety of areas to improve our customer experience and also optimize costs in our operating segments. In the Asset-Based segment, we are using enhanced tools such as barcoding, tablets, and scanning equipment to improve city pick-up and delivery productivity. In the ArcBest segment, we are using common quoting systems and predictive analytics tools which are undergoing continuous development and require ongoing investment.

We make information readily accessible to our customers through various electronic pricing, billing, and tracking services, including mobile-responsive websites which allow customers to access information about their shipments, request shipment pickup, and utilize a variety of other digital tools. Online functions tailored to the services requested by customers include bill of lading generation, pickup planning, customer-specific price quotations, proactive tracking, customized e‑mail notification, logistics reporting, dynamic rerouting, and extensible markup language (XML) connectivity. This technology allows customers to incorporate data from our systems directly into their own website or backend information systems.systems using electronic data interchange (“EDI”) standards as well as secure application programming interfaces (API). As a result, our customers can provide shipping information and support directly to their own customers.

Expedite freight transportation customers of the ArcBest segment communicate their freight needs, typically on a shipment-by-shipment basis, by means of telephone, email, internet, mobile applications, or Electronic Data Interchange (“EDI”).EDI. The information about each shipment is entered into a proprietary operating system which facilitates selection of a contracted carrier or carriers based on the carrier’s service capability, equipment availability, freight rates, and other relevant factors. Once the carrier is selected, the cost for the transportation has been agreed upon, and the carrier has committed to provide the transportation, we are in contact with the carrier through numerous means of communication (including EDI, its proprietary website, email, fax, telephone, and mobile applications) and utilize satellite tracking and communication units on the vehicles to continually update the position of equipment to meet customers’ requirements as well as to track the status of the shipment from origin to delivery. The satellite tracking and communication system automatically updates our fully-integrated internal software and provides customers with real-time electronic updates.

In 2018, ArcBest joined the Blockchain in Transport Alliance (“BiTA”). Founded in 2017, BiTA is a consortium of more than 250 freight transportation companies working to develop and set standards for the use of blockchain technology within the logistics and transportation industry.

Insurance, Safety, and Security

Generally, claims exposure in the freight transportation and logistics industry consists of workers’ compensation, third-party casualty liability, and cargo loss and damage. We are effectively self-insured for $1.0 million of each workers’ compensation loss.  For each third-party casualty loss, we are generally self-insured for $1.0 million for our Asset-Based segment and $0.3 million for our Asset-Light operations. We are also self-insured for each cargo loss, up to a $0.3 million deductible for our Asset-Based segment and a $0.1 million deductible for our ArcBest segment. We maintain insurance that we believe is adequate to cover losses in excess of such self-insured amounts or deductibles. However, we cannot

provide assurance that our insurance coverage will provide adequate protection under all circumstances or against all potential losses. We have experienced situations where excess insurance carriers have become insolvent. We pay assessments and fees to state guaranty funds in states where we have workers’ compensation self-insurance authority. In some of these states, depending on the specific state’s rules, the guaranty funds may pay excess claims if the insurer cannot pay due to insolvency. However, there can be no certainty of the solvency of individual state guaranty funds.

We have been able to obtain what we believe to be adequate insurance coverage for 20182019 and are not aware of any matters which would significantly impair our ability to obtain adequate insurance coverage at market rates for our operations in the foreseeable future. A material increase in the frequency or severity of accidents, cargo claims, or workers’ compensation claims or the material unfavorable development of existing claims could have a material adverse effect on our cost of insurance and results of operations.

As evidenced by being an eight-time winner of the American Trucking Associations’ Excellence in Security Award, a seven-time winner of the President’s Trophy for Safety, and a seven-time winner of the Excellence in Claims & Loss Prevention Award, management believes its Asset-Based operations have one of the best safety records and one of the lowest cargo claims ratios in the LTL industry.

Our operations are subject to cargo security and transportation regulations issued by the Transportation Security Administration (“TSA”) and regulations issued by the U.S. Department of Homeland Security. We are not able to accurately predict how past or future events will affect government regulations and the transportation industry. We believe that any additional security measures that may be required by future regulations could result in additional costs; however, other carriers would be similarly affected.

ReputationOther Logistics Services

We also provide other services to meet our customers’ logistics needs, such as final mile, time critical, product launch, warehousing and Responsibilitydistribution, retail logistics, supply chain optimization, and trade show shipping services.

Our Company and our brands are consistently recognized for best-in-class performance.

Competition, Pricing, and Industry Factors

Competition

Our Asset-Based segment actively competes for freight business with other national, regional, and local motor carriers and, to a lesser extent, with private carriage, domestic and international freight forwarders, railroads, and airlines. The segment competes most directly with nonunion and union LTL carriers, including YRC Freight” “FleetNet America,” “Panther Premium and YRC Regional (reporting segments of YRC Worldwide Inc.), FedEx Freight (included in the FedEx Freight reporting segment of FedEx Corporation), UPS Freight (included in the Supply Chain & Freight reporting segment of United Parcel Service, Inc.), Old Dominion Freight Line, Inc., Saia, Inc., the LTL reporting segment of Roadrunner Transportation Systems, Inc., and the LTL operations of XPO Logistics,” “U-Pack,” Inc. Competition is based primarily on price, service, and “The Skill &availability of flexible shipping options to customers. The Will.” For some marks,Asset-Based segment’s careful cargo handling and use of technology, both internally to manage its business processes and externally to provide shipment visibility to its customers, are examples of how we also have registered or are pursuing registration in certain other countries. We believe these marks or designs are of significantadd value to our business and play an important role in enhancing brand recognition and executing our marketing strategy.services.

ABF Freight’s 2016 ranking in the top 25 on Selling Power magazine’s list of “Best Companies to Sell For” marked its fourteenth consecutive year to be honored. Also in 2016, for the fourth consecutive year and the sixth time in the last eight years, ABF Freight was named as the “National LTL Carrier of the Year” by the National Shippers Strategic Transportation Council, which recognizes transportation providers on a quantitative scale in the areas of customer service, operational excellence, pricing, business relationship, leadership, and technology. In 2017, ABF Freight was selected as a SupplyChainBrain “Great Supply Chain Partner” for the second consecutive year and the third year overall. Also in 2017, ABF Freight received the “Pro Patria Award” and an “Above and Beyond Award” from the Arkansas Employer Support of the Guard and Reserve, a Department of Defense program, in recognition of its support of employees who serve in the National Guard and Reserve. Marking the ninth year in a row to be honored by Training magazine, ABF Freight was listed 12th in the “Training Top 125” in February 2018.

current market conditions.

Effective August 1, 2017, we began applying space-based pricing on shipments subject to LTL tariffs to better reflect freight shipping trends that have evolved over the last several years. These trends include the overall growth and ongoing profile shift of bulkier shipments across the entire supply chain, the acceleration in e-commerce, and the unique requirements of many shipping and logistics solutions. An increasing percentage of freight is taking up more space in trailers without a corresponding increase in weight. Space-based pricing involves the use of freight dimensions (length, width, and height) to determine applicable cubic minimum charges (“CMC”) that supplement weight-based metrics when appropriate. Traditional LTL pricing is generally weight-based, while our linehaul costs are generally space-based (i.e., costs are impacted by the volume of space required for each shipment). We believe space-based pricing better aligns our pricing mechanisms with the metrics which affect our resources and, therefore, our costs to provide logistics services. We seek to provide logistics solutions to our customers’ businesses and the unique shipment characteristics of their various products and commodities, and we believe that we are particularly experienced in handling complicated freight. The CMC is an additional pricing mechanism to better capture the value we provide in transporting these shipments.

Our Asset-Based and certain operations within our ArcBest segment assess a fuel surcharge based on the index of national on-highway average diesel fuel prices published weekly by the U.S. Department of Energy. While the fuel surcharge is dedicatedone of several components in our overall rate structure, the actual rate paid by customers is governed by market forces and the overall value of services provided to safetythe customer.

Industry Factors

According to management’s estimates and securitymarket studies by Armstrong & Associates, Inc. and the U.S. Department of Commerce, the total market potential in providing transportationthe industry segments we serve is approximately $305 billion, with $41 billion of potential revenue in the LTL market segment, $221 billion potential in the markets served by our ArcBest segment, and freight-handling services$43 billion in the maintenance and repair market served by our FleetNet segment. The LTL industry has significant barriers to its customers. Asentry and is highly competitive, as previously discussed in “Insurance, Safety, and Security”“Asset-Based Segment” within this Business section, ABFsection. Based on 2018 revenues, our Asset-Light operations represents a minor portion of the total market, which evidences the significant growth opportunity for us in the outsourced logistics market. More sophisticated supply chain practices are required as supply chains expand and become more complex, product and service needs continue to evolve, and companies look for solutions to their logistics challenges as well as for lower cost supply chain alternatives. Regulation in the transportation industry, as further discussed below, will continue to impair the competitiveness of smaller carriers in the logistics market, which may lead to tighter capacity or consolidation within certain sectors of the logistics market. In addition, disruptions from unexpected events such as natural disasters have resulted in further utilization of expedited shipping and premium logistics services and have caused companies to focus on risk management of their supply chains.

Various federal and state agencies exercise broad regulatory powers over the transportation industry, generally governing such activities as operations of and authorization to engage in motor carrier freight transportation, operations of non‑vessel‑operating common carriers, operations of ocean freight forwarders and ocean transportation intermediaries, safety, contract compliance, insurance and bonding requirements, tariff and trade policies, customs, import and export, employment practices, licensing and registration, taxation, environmental matters, data privacy and security, and financial reporting. The trucking industry faces rising costs, including costs of compliance with government regulations on safety, equipment design and maintenance, driver utilization, and fuel economy, and rising costs in certain non-industry specific areas, including health care and retirement benefits.

We are subject to various laws, rules, and regulations and are required to obtain and maintain various licenses and permits, some of which are difficult to obtain. The ArcBest segment’s network of third-party contract carriers must also comply with industry regulations, including the mandate of the Federal Motor Carrier Safety Administration (the “FMCSA”) for interstate commercial trucks to have electronic logging devices (“ELDs”) installed to monitor compliance with hours‑of‑service regulations, and other regulations such as the safety and fitness regulations of the Department of Transportation (the “DOT”), including requirements related to drug and alcohol testing and hours of service. Any future modifications to these rules and other regulations impacting the transportation industry may impact our operating practices and costs.

Seasonality

Our operations are impacted by seasonal fluctuations which affect tonnage, shipment levels, and demand for our services and, consequently, revenues and operating results. Freight shipments and operating costs of our Asset-Based and ArcBest segments can be adversely affected by inclement weather conditions. The second and third calendar quarters of each year

usually have the highest tonnage levels, while the first quarter generally has the lowest, although other factors, including the state of the U.S. and global economies, may influence quarterly freight tonnage levels.

Shipments of the ArcBest segment may decline during winter months because of post-holiday slowdowns, but expedite shipments can be subject to short-term increases depending on the impact of weather disruptions to customers’ supply chains. Plant shutdowns during summer months may affect shipments for automotive and manufacturing customers of the ArcBest segment, but severe weather events can result in higher demand for expedite services. Moving services of the ArcBest segment are impacted by seasonal fluctuations, generally resulting in higher business levels in the second and third quarters as the demand for moving services is typically stronger in the summer months.

Emergency roadside service events of the FleetNet segment are favorably impacted by extreme weather conditions that affect commercial vehicle operations, and the segment’s results of operations will be influenced by seasonal variations in service event volume.

Technology

Our advancements in technology are important to customer service and provide a competitive advantage. We continue to make investments in technology and innovations, including investments for improving the delivery of services to our customers and investments in comprehensive transportation and logistics services across ArcBest. The majority of the applications of information technology we use have been developed internally by our ArcBest Technologies subsidiary and tailored specifically for customer or internal business processing needs. ArcBest Technologies has made technology investments in a variety of areas to improve our customer experience and also optimize costs in our operating segments. In the Asset-Based segment, we are using enhanced tools such as barcoding, tablets, and scanning equipment to improve city pick-up and delivery productivity. In the ArcBest segment, we are using common quoting systems and predictive analytics tools which are undergoing continuous development and require ongoing investment.

We make information readily accessible to our customers through various electronic pricing, billing, and tracking services, including mobile-responsive websites which allow customers to access information about their shipments, request shipment pickup, and utilize a variety of other digital tools. Online functions tailored to the services requested by customers include bill of lading generation, pickup planning, customer-specific price quotations, proactive tracking, customized e‑mail notification, logistics reporting, dynamic rerouting, and extensible markup language (XML) connectivity. This technology allows customers to incorporate data from our systems directly into their own website or backend information systems using electronic data interchange (“EDI”) standards as well as secure application programming interfaces (API). As a result, our customers can provide shipping information and support directly to their own customers.

Expedite freight transportation customers of the ArcBest segment communicate their freight needs, typically on a shipment-by-shipment basis, by means of telephone, email, internet, mobile applications, or EDI. The information about each shipment is entered into a proprietary operating system which facilitates selection of a contracted carrier or carriers based on the carrier’s service capability, equipment availability, freight rates, and other relevant factors. Once the carrier is selected, the cost for the transportation has been agreed upon, and the carrier has committed to provide the transportation, we are in contact with the carrier through numerous means of communication and utilize satellite tracking and communication units on the vehicles to continually update the position of equipment to meet customers’ requirements as well as to track the status of the shipment from origin to delivery. The satellite tracking and communication system automatically updates our fully-integrated internal software and provides customers with real-time electronic updates.

In 2018, ArcBest joined the Blockchain in Transport Alliance (“BiTA”). Founded in 2017, BiTA is a consortium of more than 250 freight transportation companies working to develop and set standards for the use of blockchain technology within the logistics and transportation industry.

Insurance, Safety, and Security

Generally, claims exposure in the freight transportation and logistics industry consists of workers’ compensation, third-party casualty liability, and cargo loss and damage. We are effectively self-insured for $1.0 million of each workers’ compensation loss.  For each third-party casualty loss, we are generally self-insured for $1.0 million for our Asset-Based segment and $0.3 million for our Asset-Light operations. We are also self-insured for each cargo loss, up to a $0.3 million deductible for our Asset-Based segment and a $0.1 million deductible for our ArcBest segment. We maintain insurance that we believe is adequate to cover losses in excess of such self-insured amounts or deductibles. However, we cannot

provide assurance that our insurance coverage will provide adequate protection under all circumstances or against all potential losses. We have experienced situations where excess insurance carriers have become insolvent. We pay assessments and fees to state guaranty funds in states where we have workers’ compensation self-insurance authority. In some of these states, depending on the specific state’s rules, the guaranty funds may pay excess claims if the insurer cannot pay due to insolvency. However, there can be no certainty of the solvency of individual state guaranty funds.

We have been able to obtain what we believe to be adequate insurance coverage for 2019 and are not aware of any matters which would significantly impair our ability to obtain adequate insurance coverage at market rates for our operations in the foreseeable future. A material increase in the frequency or severity of accidents, cargo claims, or workers’ compensation claims or the material unfavorable development of existing claims could have a material adverse effect on our cost of insurance and results of operations.

As evidenced by being an eight-time winner of the American Trucking Associations’ Excellence in Security Award, a seven-time winner of the President’s Trophy for Safety, and a seven-time winner of the Excellence in Claims & Loss Prevention Award. In January 2017, two ABF Freight drivers were named by the American Trucking Associations as captainsAward, management believes its Asset-Based operations have one of the 2017-2018 “America’s Road Team,” continuing the tradition of ABF Freight’s representation in this select program based on the drivers’ exceptionalbest safety records and their strong commitment to safety and professionalism.one of the lowest cargo claims ratios in the LTL industry.

Our operations are subject to cargo security and transportation regulations issued by the Transportation Security Administration (“TSA”) and regulations issued by the U.S. Department of Homeland Security. We are actively involved in effortsnot able to promote a cleaner environment by reducing both fuel consumption and emissions. For many years, our Asset-Based segment has voluntarily limited the maximum speed of its trucks, which reduces fuel consumption and emissions and contributes to ABF Freight’s excellent safety record. Our Asset-Based segment utilizes engine idle management programming to automatically shut down engines of parked tractors. Fuel consumption and emissions have also been minimized through a strict equipment maintenance schedule. In 2015, our Asset-Based segment began voluntarily installing aerodynamic aids on its fleet of over-the-road trailers to further enhance fuel economy and reduce emissions.  In 2006, ABF Freight was accepted in the EPA’s SmartWay Transport Partnership, a collaboration between the EPAaccurately predict how past or future events will affect government regulations and the freight transportation industryindustry. We believe that helps freight shippers,any additional security measures that may be required by future regulations could result in additional costs; however, other carriers and logistics companies reduce greenhouse gases and diesel emissions. In recognition of ABF Freight’s industry leadership in freight supply chain environmental performance and energy efficiency, the EPA’s SmartWay Transport Partnership awarded ABF Freight a SmartWay Excellence Award in 2014. For the past eight years, ABF Freight was recognized in Inbound Logistics’ annual list of supply chain partners committed to sustainability. Furthermore, in association with the American Trucking Associations’ Sustainability Task Force, ABF Freight has participated in other opportunities to address environmental issues.would be similarly affected.

ArcBestAsset-Based Segment

ArcBest Corporation was named a “Top 50 U.S. Third-party Logistics Provider” by Armstrong & Associates, Inc. in 2017. Our ArcBestAsset-Based segment was recognized by Transport Topics on the “Top Freight Brokerage Firms of 2017” list, ranking eighteenth – up from twenty-first in 2016. In recognitionprovides LTL services through ABF Freight’s motor carrier operations. Asset-Based revenues accounted for approximately 69% of our Expedite operations’ commitment to quality, Panther Premium Logistics was awardedtotal revenues before other revenues and intercompany eliminations in 2018. For the “Questyear ended December 31, 2018, no single customer accounted for Quality Award” by Logistics Magazine for the fifth consecutive year. In 2016, Panther received the “National Expedited Carriermore than 4% of the Year” award for the second consecutive year by the National Shippers Strategic Transportation Council. U-Pack received its first “Quest for Quality” award from Logistics Magazine in 2017, being honoredrevenues in the Household Goods & High Value Goods category.

Financial Information About Geographic Areas

Classifications of operations or revenues by geographic location beyond the descriptions previously provided are impractical and, therefore, are not provided. Our foreign operations are not significant.

Our nonunion defined benefit pension plan trust holds investmentsapplicable 2008 to 2013 supplemental agreements; wage rate increases in short-duration debt securitieseach year of the contract, beginning July 1, 2018; ratification bonuses for qualifying employees; profit-sharing bonuses upon the Asset-Based segment’s achievement of certain annual operating ratios for any full calendar year under the contract; and cash equivalent, fixed income, and floating rate loan mutual funds. Declineschanges to purchased transportation provisions with certain protections for road drivers as specified in the value of plan assets resulting from instability in the financial markets, general economic downturn, or other economic factors beyond our control could diminish the funded status of the nonunion defined benefit pension plan and potentially increase our requirement to make contributions to the plan, including an increase in our cash funding requirement prior to the final distribution of benefits to plan participants. A change in the interest rates used to calculate our funding requirements under the Pension Protection Act of 2006 (the “PPA”) may also impact contributions required to fund our plan. Significant plan contribution requirements could reduce the cash available for working capital and other business needs and opportunities. An increase in required pension plan contributions may adversely impact our financial condition and liquidity. Substantial future investment losses on pension plan assets would increase pension expense in the years following the losses. In addition, a change in the discount rate used to calculate our obligations for our nonunion defined benefit pension plan and postretirement health benefit plan for financial statement purposes would impact the accumulated benefit obligation and expense for these plans. An increase in expense for these pension and postretirement plans may adversely impact our results of operations.

We could also experience losses on investments related to our cash surrender value of variable life insurance policies, which may negatively impact our results of operations.

Furthermore, it is not possible to predict the effects of actual or threatened armed conflicts, terrorist attacks, or political and/or civil unrest on the economy or on consumer confidence in the United States or the impact, if any, on our future results of operations or financial condition.

Our nonunion defined benefit pension plan could have greater than anticipated funding requirements, which may adversely affect our financial condition and liquidity.

In the fourth quarter of 2017, an amendment was executed to terminate our nonunion defined benefit pension plan as of December 31, 2017, as further discussed in Note I to our consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K. Lump sum benefit distributions to participantscontract. The 2018 ABF NMFA and the purchase of an annuity contract to settle the pension obligation related to benefitssupplemental agreements provide for which participants elect to defer payment until a later date, are likely to occur primarily in the second half of 2018. Our requirement to fund the plan prior to the final distribution of benefits to plan participants, the amount of which will be determined by the plan’s actuary, is currently estimated to require a cash payment of approximately $10.0 million, although there can be no assurances in this regard, as the actual amount is dependent on various factors, including final benefit calculations, the benefit elections made by plan participants, interest rates, the value of plan assets, and the cost to purchase an annuity contract to settle the pension obligation related to benefits for which participants elect to defer payment until a later date.

We depend on services provided by third parties, and increased costs or disruption of these services, and claims arising from these services, could adversely affect our business, results of operations, financial condition, cash flows, and customer relationships.

A reduction in the availability of rail services or services provided by third-party capacity providers to meet customer requirements, as well as higher utilization of third-party agents to maintain service levels in periods of tonnage growth, could increase purchased transportation costs which we may be unable to pass along to our customers. If a disruption or reduction in transportation services from our rail or other third-party service providers were to occur, we could be faced with business interruptions that could cause us to fail to meet the needs of our customers. In addition, we may not be able to negotiate competitive contracts with railroads or other third-party service providers to expand our capacity, add additional routes, or obtain services at costs that are acceptable to us or our customers. If these situations occur, our business, results of operations, financial condition, cash flows, and customer relationships could be adversely impacted.

Our ability to secure the services of third-party service providers is affected by many risks beyond our control, including the inability to obtain the services of reliable third parties at competitive prices; the shortage of quality third-party providers, including owner operators for our Expedite operations and drivers of contracted carriers for our Truckload and Truckload-Dedicated operations; shortages in available cargo capacity; equipment shortages in the transportation industry, particularly among contracted truckload carriers; changes in government regulations affecting the transportation industry and their related impact on operations, such as hours-of-service rules and the ELD mandate discussed in “Competition, Pricing, and Industry Factors” within Part I, Item 1 (Business) of this Annual Report on Form 10-K; labor disputes; or a significant interruption in service or stoppage in third-party transportation services. Each of these risks could have a material adverse effect on the operating results of our Asset-Light businesses.

Our management team is an important part of our business and loss of key employees could impair our business, results of operations, and financial condition.

We benefit from the leadership and experience of our senior management team and other key employees and depend on their continued services to successfully implement our business strategy. The unexpected loss of key employees or inability to execute our training and succession planning strategies could have an adverse effect on our business, results of operations, and financial condition if we are unable to secure replacement personnel that have sufficient experience in our industry and in the management of our business.

Our Credit Facility and accounts receivable securitization program contain customary financial and other customary restrictive covenants that may limit our future operations. A default under these financing arrangements or changes in regulations which impact the availability of funds or our costs to borrow under our financing arrangements could cause a material adverse effect on our liquidity, financial condition, and results of operations.

Our Credit Agreement, which governs our Credit Facility, contains representations and warranties, conditions, and events of default that are customary for financings of this type including, but not limited to, a minimum interest coverage ratio, a maximum adjusted leverage ratio, and limitations on incurrence of debt, investments, liens on assets, certain sale and leaseback transactions, transactions with affiliates, mergers, consolidations, and sales of assets. Our accounts receivable securitization program also contains affirmative and negative covenants, and events of default that are customary for financings of this type, including a maximum adjusted leverage ratio and requirements to maintain certain characteristics of the receivables, such as rates of delinquency, default, and dilution.

If we default under the terms of the Credit Agreement or our accounts receivable securitization program and fail to obtain appropriate amendments to or waivers under the applicable financing arrangement, our borrowings under such facilities could be immediately declared due and payable. In the event of a default under either of these facilities, we could automatically default on the other of these facilities and on our outstanding notes payable and other financing agreements, unless the lenders to these facilities choose not to exercise remedies or to otherwise allow us to cure the default. If we fail to pay the amount due under our Credit Facility or accounts receivable securitization program, the lenders could proceed against the collateral by which our Credit Facility is secured, our borrowing capacity may be limited, or the facilities could be terminated. If acceleration of outstanding borrowings occurs or if the facilities are terminated, we may have difficulty borrowing additional funds sufficient to refinance the accelerated debt or entering into new credit or debt arrangements, and, if available, the terms of the financing may not be acceptable. A default under the Credit Agreement or accounts receivable securitization program, changes in regulations which impact the availability of funds or our costs to borrow under our financing arrangements, or our inability to renew our financing arrangements with terms that are acceptable to us, could have a material adverse effect on our liquidity and financial condition.

In addition, failing to achieve certain financial ratios as required by our Credit Facility and accounts receivable securitization program could adversely affect our ability to finance our operations, make strategic acquisitions or investments, or plan for or react to market conditions or otherwise execute our business strategies.

We have significant ongoing capital requirements that could have a material adverse effect on our business, profitability, and growth if we are unable to generate sufficient cash from operations or obtain sufficient financing on favorable terms or properly forecast capital needs to correspond with business volumes.

We have significant ongoing capital requirements. If we are not able to generate sufficient cash from operations in the future, our growth could be limited; it may be necessary for us to utilize our existing financing arrangements to a greater extent or enter into additional financing or leasing arrangements, possibly on less favorable terms; or our revenue equipment may have to be held for longer periods, which would result in increased expenditures for maintenance. Forecasting business volumes involves many factors, including general economic trends and the impact of competition, which are subject to uncertainty and beyond our control. If we do not accurately forecast our future capital investment needs, especially for revenue equipment, in relation to corresponding business levels, we could have excess capacity or insufficient capacity. In addition, our Credit Facility contains provisions that could limit our level of annual capital expenditures. If we were unable to properly forecast capital needs and/or were unable to generate sufficient cash from operations, obtain adequate financing at acceptable terms, or if our capital spending was otherwise limited, there could be an adverse effect on our business, profitability, and growth.

applicable 2008 to 2013 supplemental agreements; wage rate increases in each year of the contract, beginning July 1, 2018; ratification bonuses for qualifying employees; profit-sharing bonuses upon the Asset-Based segment’s achievement of certain annual operating ratios for any full calendar year under the contract; and changes to purchased transportation provisions with certain protections for road drivers as specified in the contract. The 2018 ABF NMFA and the related supplemental agreements provide for contributions to multiemployer pension plans frozen at the current rates for each fund, continuation of existing health coverage, and annual contribution rate increases to multiemployer health and welfare plans maintained for the benefit of ABF's employees who are members of the IBT. Under the 2018 ABF NMFA, the contractual wage and benefits costs, including the ratification bonuses and vacation restoration, are estimated to increase approximately 2.0% on a compounded annual basis through the end of the agreement. Profit-sharing bonuses based on the Asset-Based segment’s annual operating ratios for any full calendar year under the contract would represent an additional increase in costs under the 2018 ABF NMFA.

Amendments to the Employee Retirement Income Security Act of 1974 (“ERISA”), pursuant to the Multiemployer Pension Plan Amendments Act of 1980 (the “MPPA Act”), substantially expanded the potential liabilities of employers who participate in multiemployer pension plans. Under ERISA, as amended by the MPPA Act, an employer who contributes to a multiemployer pension plan and the members of such employer’s controlled group are jointly and severally liable for their share of the plan’s unfunded vested benefits in the event the employer ceases to have an obligation to contribute to the plan or substantially reduces its contributions to the plan (i.e., in the event of a complete or partial withdrawal from the multiemployer plans). The Multiemployer Pension Reform Act of 2014 (the “Reform Act”), which was included in the Consolidated and Further Continuing Appropriations Act of 2015 (the “CFCAA”) that was signed into law on December 16, 2014, includes provisions to address the funding of multiemployer pension plans in critical and declining status. Provisions of the Reform Act include, among others, providing qualifying plans the ability to self-correct funding issues, subject to various requirements and restrictions, including applying to the U.S. Department of the Treasury (the “Treasury Department”) for the reduction of certain accrued benefits. Through the term of its current collective bargaining agreement, ABF Freight’s multiemployer pension plan contribution obligations generally will be satisfied by making the specified contributions when due. However, we cannot determine with any certainty the contributions that will be required under future collective bargaining agreements for ABF Freight’s contractual employees. See Note I to the consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K for more specific disclosures regarding the multiemployer pension plans to which ABF Freight contributes.

ABF Freight operates in a highly competitive industry which consists predominantly of nonunion motor carriers. Nonunion competitors have a lower fringe benefit cost structure and less stringent labor work rules, and certain carriers also have lower wage rates for their freight-handling and driving personnel. Wage and benefit concessions granted to certain union competitors also allow for a lower cost structure. ABF Freight has continued to address with the IBT the effect of the wage and benefit cost structure on its operating results. The combined effect under the contractual labor agreement in place prior to the 2018 ABF NMFA of cost reductions, lowered cost increases throughout the contract period, and increased flexibility in labor work rules were important factors in bringing ABF Freight’s labor cost structure closer in line with that of its competitors; however, ABF Freight continues to pay some of the highest benefit contribution rates in the industry. These rates include contributions to multiemployer plans, a portion of which are used to fund benefits for individuals who were never employed by ABF Freight. Information provided by a large multiemployer pension plan to which ABF Freight contributes indicates that approximately 50% of the plan’s benefit payments are made to retirees of companies that are no longer contributing employers to that plan.

Asset-Light Operations

The ArcBest and FleetNet reportable segments, combined, represent our Asset-Light operations. Our Asset-Light operations are a key component of our strategy to offer customers end-to-end logistics solutions, designed to satisfy the complex supply chain and unique shipping requirements they encounter. Through unique methods and processes, including technology solutions and the use of third-party service providers, our Asset-Light operations provide various logistics and maintenance services without significant investment in revenue equipment or real estate.

For the year ended December 31, 2018, the combined revenues of our Asset-Light operations accounted for approximately 31% of our total revenues before other revenues and intercompany eliminations. For the year ended December 31, 2018, no single customer accounted for more than 4% of the ArcBest segment’s revenues, and the segment’s 10 largest customers, on a combined basis, accounted for approximately 20% of its revenues. Note M to our consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K contains additional segment financial information, including revenues and operating income for the years ended December 31, 2018, 2017, and 2016.

ArcBest Segment

As previously discussed in “Strategy” within this Business section, our ArcBest segment originated with the formation of ABF Logistics in July 2013, when we strategically aligned the sales and operations functions of our organically-developed logistics businesses. The ArcBest segment includes the ground expedite services of the Panther Premium Logistics brand; household goods moving services under the U-Pack brand, for which the majority of the moves are provided with our Asset-Based operations; and the acquired operations of Smart Lines, Bear, and LDS. Under our enhanced market approach to offer customers a single source of end-to-end logistics, the service offerings of the ArcBest segment continue to become more integrated. Management’s operating decisions have become more focused on the ArcBest segment’s combined operations, rather than individual service offerings within the segment’s operations. The ArcBest segment offers the following solutions:

Expedite

Through the Panther Premium Logistics brand, we offer expedite freight transportation services to commercial and government customers and we offer premium logistics services that involve the rapid deployment of highly specialized equipment to meet extremely specific linehaul requirements, such as temperature control, hazardous materials, geofencing (routing a shipment across a mandatory, defined route with satellite monitoring and automated alerts concerning any deviation from the route), specialized government cargo, security services, and life sciences. Through these services, ArcBest solves the toughest shipping and logistics challenges that customers face through a global network of owner operators and contract carriers.

Substantially all of the network capacity for our expedite operations is provided by third-party carriers, including owner operators, ground linehaul providers, cartage agents, and other transportation asset providers, which are selected based on their ability to serve our customers effectively with respect to price, technology capabilities, geographic coverage, and quality of service. Third-party owned vehicles are driven by independent contract drivers and by drivers engaged directly by independent owners of multiple pieces of equipment, commonly referred to as fleet owners. Our expedite operations own a fleet of trailers, the communication devices used by its owner operators, and certain highly specialized equipment, primarily temperature-controlled and temperature-validated trailers, to meet the service requirements of certain customers.

Truckload and Truckload-Dedicated

Our truckload and truckload-dedicated services provide third-party transportation brokerage by sourcing a variety of capacity solutions, including dry van over the road, temperature-controlled and refrigerated, flatbed, intermodal or container shipping, and specialized equipment, coupled with strong technology and carrier- and customer-based Web tools. We offer a growing network of 26,000 vetted service providers, with services to 50 states, Canada, and Mexico. Additional value is created for customers through seamless access to the ABF Freight network.

International

Our International services provide international ocean and air shipping solutions by partnering with ocean shipping lines and air freight carriers worldwide. As a non-vessel operating common carrier, we provide less-than-container load and full‑container load service, offering ocean transport to approximately 90% of the total ocean international market to and from the United States.

Managed Transportation

We also provide freight transportation management services for customers. ArcBest seeks to offer value through identifying specific challenges relating to customers’ supply chain needs and providing customized solutions utilizing technology, both internally to manage its business processes and externally to provide shipment and inventory visibility to its customers. Additional value is created for customers through seamless access to the ABF Freight network, the Panther fleet, and other ArcBest capacity sources, offering strategic supply chain solutions with unique access to assured capacity.

Moving

Our moving services offer flexibility and convenience in the way people move through targeted service offerings for the “do-it-yourself” consumer and corporate account employee relocations. We offer these targeted services at competitive prices that reflect the additional value customers find in our convenient, reliable moving service offerings. Industry leading technology, customer-friendly interfaces, and supply chain solutions are combined to provide a wide range of options customized to meet unique customer needs.

Other Logistics Services

We also provide other services to meet our customers’ logistics needs, such as final mile, time critical, product launch, warehousing and distribution, retail logistics, supply chain optimization, and trade show shipping services.

FleetNet Segment

The FleetNet segment includes the results of operations of FleetNet America, Inc. (“FleetNet”), our subsidiary that provides roadside assistance and maintenance management services for commercial vehicles to customers in the United States and Canada through a network of third-party service providers. FleetNet began in 1953 as the internal breakdown department for Carolina Freight Carriers Corp. In 1993, the department was incorporated as Carolina Breakdown Service, Inc. to allow the opportunity for other trucking companies to take advantage of the established nationwide service. In 1995, we purchased WorldWay Corporation, which operated various subsidiaries including Carolina Freight Carriers Corp. and Carolina Breakdown Service, Inc. The name of Carolina Breakdown Service, Inc. was changed to FleetNet America, Inc. in 1997.

Competition, Pricing, and Industry Factors

Competition

Our Asset-Based segment actively competes for freight business with other national, regional, and local motor carriers and, to a lesser extent, with private carriage, domestic and international freight forwarders, railroads, and airlines. The segment competes most directly with nonunion and union LTL carriers, including YRC Freight and YRC Regional (reporting segments of YRC Worldwide Inc.), FedEx Freight (included in the FedEx Freight reporting segment of FedEx Corporation), UPS Freight (included in the Supply Chain & Freight reporting segment of United Parcel Service, Inc.), Old Dominion Freight Line, Inc., Saia, Inc., the LTL reporting segment of Roadrunner Transportation Systems, Inc., and the LTL operations of XPO Logistics, Inc. Competition is based primarily on price, service, and availability of flexible shipping options to customers. The Asset-Based segment’s careful cargo handling and use of technology, both internally to manage its business processes and externally to provide shipment visibility to its customers, are examples of how we add value to our services.

Our ArcBest segment operates in a very competitive asset-light logistics market that includes approximately 17,000 active brokerage authorities, as well as asset-based truckload carriers and logistics companies, large expedite carriers including FedEx Custom Critical, Inc., smaller expedite carriers, foreign and U.S.-based non-vessel-operating common carriers, freight forwarders, internal shipping departments at companies that have substantial transportation requirements, smaller niche service providers, and a wide variety of solution providers, including large integrated transportation companies as well as regional warehouse and transportation management firms. ArcBest’s moving services compete with truck rental, self-move, and van line service providers, and a number of emerging self-move competitors who offer moving and storage container service. Quality of service, technological capabilities, and industry expertise are critical differentiators among the competition. In particular, companies with advanced systems that offer optimized shipping solutions, real-time visibility of shipments, verification of chain of custody procedures, and advanced security have significant operational advantages and create enhanced customer value. ArcBest’s performance in each of these areas of competitive distinction has enabled the segment to secure business and drive growth within our Asset-Light operations.

FleetNet competes in the commercial vehicle maintenance and repair industry in two major sectors: emergency roadside and preventive maintenance. FleetNet competes directly against other third-party service providers, automotive fleet managers, leasing companies, and companies handling repairs in-house via individual service providers. While no one company encompasses all of FleetNet’s service offerings, competition is based primarily on providing maintenance solutions services. In partnership with best-in-class third-party vendors, FleetNet offers flexible, customized solutions and utilizes technology to provide valuable information and data to minimize fleet downtime, reduce maintenance events, and lower total maintenance costs for its customers.

Pricing

Approximately one third of our Asset-Based business is subject to base LTL tariffs, which are affected by general rate increases, combined with individually negotiated discounts. Rates on the other two thirds of our Asset-Based business, including business priced in the spot market, are subject to individual pricing arrangements that are negotiated at various times throughout the year. The majority of the business that is subject to negotiated pricing arrangements is associated with larger customer accounts with annually negotiated pricing arrangements, and the remaining business is priced on an individual shipment basis considering each shipment’s unique profile, the value we provide to the customer, and current market conditions.

Effective August 1, 2017, we began applying space-based pricing on shipments subject to LTL tariffs to better reflect freight shipping trends that have evolved over the last several years. These trends include the overall growth and ongoing profile shift of bulkier shipments across the entire supply chain, the acceleration in e-commerce, and the unique requirements of many shipping and logistics solutions. An increasing percentage of freight is taking up more space in trailers without a corresponding increase in weight. Space-based pricing involves the use of freight dimensions (length, width, and height) to determine applicable cubic minimum charges (“CMC”) that supplement weight-based metrics when appropriate. Traditional LTL pricing is generally weight-based, while our linehaul costs are generally space-based (i.e., costs are impacted by the volume of space required for each shipment). We believe space-based pricing better aligns our pricing mechanisms with the metrics which affect our resources and, therefore, our costs to provide logistics services. We seek to provide logistics solutions to our customers’ businesses and the unique shipment characteristics of their various products and commodities, and we believe that we are particularly experienced in handling complicated freight. The CMC is an additional pricing mechanism to better capture the value we provide in transporting these shipments.

Our Asset-Based and certain operations within our ArcBest segment assess a fuel surcharge based on the index of national on-highway average diesel fuel prices published weekly by the U.S. Department of Energy. While the fuel surcharge is one of several components in our overall rate structure, the actual rate paid by customers is governed by market forces and the overall value of services provided to the customer.

Industry Factors

According to management’s estimates and market studies by Armstrong & Associates, Inc. and the U.S. Department of Commerce, the total market potential in the industry segments we serve is approximately $305 billion, with $41 billion of potential revenue in the LTL market segment, $221 billion potential in the markets served by our ArcBest segment, and $43 billion in the maintenance and repair market served by our FleetNet segment. The LTL industry has significant barriers to entry and is highly competitive, as previously discussed in “Asset-Based Segment” within this Business section. Based on 2018 revenues, our Asset-Light operations represents a minor portion of the total market, which evidences the significant growth opportunity for us in the outsourced logistics market. More sophisticated supply chain practices are required as supply chains expand and become more complex, product and service needs continue to evolve, and companies look for solutions to their logistics challenges as well as for lower cost supply chain alternatives. Regulation in the transportation industry, as further discussed below, will continue to impair the competitiveness of smaller carriers in the logistics market, which may lead to tighter capacity or consolidation within certain sectors of the logistics market. In addition, disruptions from unexpected events such as natural disasters have resulted in further utilization of expedited shipping and premium logistics services and have caused companies to focus on risk management of their supply chains.

Various federal and state agencies exercise broad regulatory powers over the transportation industry, generally governing such activities as operations of and authorization to engage in motor carrier freight transportation, operations of non‑vessel‑operating common carriers, operations of ocean freight forwarders and ocean transportation intermediaries, safety, contract compliance, insurance and bonding requirements, tariff and trade policies, customs, import and export, employment practices, licensing and registration, taxation, environmental matters, data privacy and security, and financial reporting. The trucking industry faces rising costs, including costs of compliance with government regulations on safety, equipment design and maintenance, driver utilization, and fuel economy, and rising costs in certain non-industry specific areas, including health care and retirement benefits.

We are subject to various laws, rules, and regulations and are required to obtain and maintain various licenses and permits, some of which are difficult to obtain. The ArcBest segment’s network of third-party contract carriers must also comply with industry regulations, including the mandate of the Federal Motor Carrier Safety Administration (the “FMCSA”) for interstate commercial trucks to have electronic logging devices (“ELDs”) installed to monitor compliance with hours‑of‑service regulations, and other regulations such as the safety and fitness regulations of the Department of Transportation (the “DOT”), including requirements related to drug and alcohol testing and hours of service. Any future modifications to these rules and other regulations impacting the transportation industry may impact our operating practices and costs.

Seasonality

Our operations are impacted by seasonal fluctuations which affect tonnage, shipment levels, and demand for our services and, consequently, revenues and operating results. Freight shipments and operating costs of our Asset-Based and ArcBest segments can be adversely affected by inclement weather conditions. The second and third calendar quarters of each year

usually have the highest tonnage levels, while the first quarter generally has the lowest, although other factors, including the state of the U.S. and global economies, may influence quarterly freight tonnage levels.

Shipments of the ArcBest segment may decline during winter months because of post-holiday slowdowns, but expedite shipments can be subject to short-term increases depending on the impact of weather disruptions to customers’ supply chains. Plant shutdowns during summer months may affect shipments for automotive and manufacturing customers of the ArcBest segment, but severe weather events can result in higher demand for expedite services. Moving services of the ArcBest segment are impacted by seasonal fluctuations, generally resulting in higher business levels in the second and third quarters as the demand for moving services is typically stronger in the summer months.

Emergency roadside service events of the FleetNet segment are favorably impacted by extreme weather conditions that affect commercial vehicle operations, and the segment’s results of operations will be influenced by seasonal variations in service event volume.

Technology

Our advancements in technology are important to customer service and provide a competitive advantage. We continue to make investments in technology and innovations, including investments for improving the delivery of services to our customers and investments in comprehensive transportation and logistics services across ArcBest. The majority of the applications of information technology we use have been developed internally by our ArcBest Technologies subsidiary and tailored specifically for customer or internal business processing needs. ArcBest Technologies has made technology investments in a variety of areas to improve our customer experience and also optimize costs in our operating segments. In the Asset-Based segment, we are using enhanced tools such as barcoding, tablets, and scanning equipment to improve city pick-up and delivery productivity. In the ArcBest segment, we are using common quoting systems and predictive analytics tools which are undergoing continuous development and require ongoing investment.

We make information readily accessible to our customers through various electronic pricing, billing, and tracking services, including mobile-responsive websites which allow customers to access information about their shipments, request shipment pickup, and utilize a variety of other digital tools. Online functions tailored to the services requested by customers include bill of lading generation, pickup planning, customer-specific price quotations, proactive tracking, customized e‑mail notification, logistics reporting, dynamic rerouting, and extensible markup language (XML) connectivity. This technology allows customers to incorporate data from our systems directly into their own website or backend information systems using electronic data interchange (“EDI”) standards as well as secure application programming interfaces (API). As a result, our customers can provide shipping information and support directly to their own customers.

Expedite freight transportation customers of the ArcBest segment communicate their freight needs, typically on a shipment-by-shipment basis, by means of telephone, email, internet, mobile applications, or EDI. The information about each shipment is entered into a proprietary operating system which facilitates selection of a contracted carrier or carriers based on the carrier’s service capability, equipment availability, freight rates, and other relevant factors. Once the carrier is selected, the cost for the transportation has been agreed upon, and the carrier has committed to provide the transportation, we are in contact with the carrier through numerous means of communication and utilize satellite tracking and communication units on the vehicles to continually update the position of equipment to meet customers’ requirements as well as to track the status of the shipment from origin to delivery. The satellite tracking and communication system automatically updates our fully-integrated internal software and provides customers with real-time electronic updates.

In 2018, ArcBest joined the Blockchain in Transport Alliance (“BiTA”). Founded in 2017, BiTA is a consortium of more than 250 freight transportation companies working to develop and set standards for the use of blockchain technology within the logistics and transportation industry.

Insurance, Safety, and Security

Generally, claims exposure in the freight transportation and logistics industry consists of workers’ compensation, third-party casualty liability, and cargo loss and damage. We are effectively self-insured for $1.0 million of each workers’ compensation loss.  For each third-party casualty loss, we are generally self-insured for $1.0 million for our Asset-Based segment and $0.3 million for our Asset-Light operations. We are also self-insured for each cargo loss, up to a $0.3 million deductible for our Asset-Based segment and a $0.1 million deductible for our ArcBest segment. We maintain insurance that we believe is adequate to cover losses in excess of such self-insured amounts or deductibles. However, we cannot

provide assurance that our insurance coverage will provide adequate protection under all circumstances or against all potential losses. We have experienced situations where excess insurance carriers have become insolvent. We pay assessments and fees to state guaranty funds in states where we have workers’ compensation self-insurance authority. In some of these states, depending on the specific state’s rules, the guaranty funds may pay excess claims if the insurer cannot pay due to insolvency. However, there can be no certainty of the solvency of individual state guaranty funds.

We have been able to obtain what we believe to be adequate insurance coverage for 2019 and are not aware of any matters which would significantly impair our ability to obtain adequate insurance coverage at market rates for our operations in the foreseeable future. A material increase in the frequency or severity of accidents, cargo claims, or workers’ compensation claims or the material unfavorable development of existing claims could have a material adverse effect on our cost of insurance and results of operations.

As evidenced by being an eight-time winner of the American Trucking Associations’ Excellence in Security Award, a seven-time winner of the President’s Trophy for Safety, and a seven-time winner of the Excellence in Claims & Loss Prevention Award, management believes its Asset-Based operations have one of the best safety records and one of the lowest cargo claims ratios in the LTL industry.

Our operations are subject to cargo security and transportation regulations issued by the Transportation Security Administration (“TSA”) and regulations issued by the U.S. Department of Homeland Security. We are not able to accurately predict how past or future events will affect government regulations and the transportation industry. We believe that any additional security measures that may be required by future regulations could result in additional costs; however, other carriers would be similarly affected.

Environmental and Other Government Regulations

We are subject to federal, state, and local environmental laws and regulations relating to, among other things: emissions control, transportation of hazardous materials, underground and aboveground storage tanks, stormwater pollution prevention, contingency planning for spills of petroleum products, and disposal of waste oil.

In August 2016, the U.S. Environmental Protection Agency (“EPA”) and the National Highway Traffic Safety Administration (the “NHTSA”) jointly finalized a national program establishing a second phase of greenhouse gas emissions (“EPA/NHTSA Phase 2”), imposing new fuel efficiency standards for medium- and heavy-duty vehicles, such as those operated by our Asset-Based segment, for model years 2021-2027 and also instituting fuel efficiency improvement technology requirements for trailer model years 2018-2027. In October 2017, the U.S. Court of Appeals for the District of Columbia stayed the portion of the EPA/NHTSA Phase 2 Final Rule regarding the trailer regulations, and the review of the Final Rule has an indefinite date of final ruling. In February 2018, the California Air Resources Board (the “CARB”) approved plans to retain two provisions of the EPA/NHTSA Phase 2 Final Rule that would regulate glider kits and trailers. In the event the EPA does not enforce the trailer regulations of EPA/NHTSA Phase 2, certain other states may also individually enact legislation to enforce the regulations. A number of states have individually enacted, and California and certain other states may continue to enact, legislation relating to engine emissions, trailer regulations, fuel economy, and/or fuel formulation, such as regulations enacted by the CARB. At the present time, management believes that these regulations may not result in significant net additional overall costs should the technologies developed for tractors, as required in the EPA/NHTSA Phase 2 rulemaking, prove to be as cost-effective as forecasted by the EPA and the NHTSA.

In November 2018, the EPA launched the “Cleaner Trucks Initiative” (“CTI”) which includes plans for future rulemaking to reduce nitrogen oxide (“NOx”) emissions.  According to the CTI announcement, the EPA plans to publish a new Notice of Proposed Rulemaking for tighter NOx emissions by 2020. One planned feature of the initiative is to coordinate emissions standards nationwide, which will prevent a further patchwork of state and local emissions regulations and should make compliance much easier for the industry. Since no details of implementation timeframe(s) nor target reductions of NOx emissions are yet released for CTI, it is difficult to assess the impact this future regulation may have.

While fuel consumption and emissions may be reduced under the new standards, emission-related regulatory actions have historically resulted in increased costs of revenue equipment, diesel fuel, and equipment maintenance, and future legislation, if enacted, could result in increases in these and other costs. We are unable to determine with any certainty the effects of any future climate change legislation beyond the currently enacted regulations, and there can be no assurance that more restrictive regulations than those previously described will not be enacted either federally or locally.

Our Asset-Based operations store fuel for use in tractors and trucks in 62 underground tanks located in 18 states. Maintenance of such tanks is regulated at the federal and, in most cases, state levels. Management believes we are in substantial compliance with all such regulations. The underground storage tanks are required to have leak detection systems, and we are not aware of any leaks from such tanks that could reasonably be expected to have a material adverse effect on our operating results.

Certain of our Asset-Based service center facilities operate with non-discharge certifications or stormwater permits under the federal Clean Water Act (“CWA”). The stormwater permits require periodic monitoring and reporting of stormwater sampling results and establish maximum levels of certain contaminants that may be contained in such samples.

We have received notices from the EPA and others that we have been identified as a potentially responsible party under the Comprehensive Environmental Response Compensation and Liability Act, or other federal or state environmental statutes, at several hazardous waste sites. After investigating our subsidiaries’ involvement in waste disposal or waste generation at such sites, we have either agreed to de minimis settlements or determined that our obligations, other than those specifically accrued with respect to such sites, would involve immaterial monetary liability, although there can be no assurance in this regard. It is anticipated that the resolution of our environmental matters could take place over several years. Our reserves for environmental cleanup costs are estimated based on management’s experience with similar environmental matters and on testing performed at certain sites.

We are actively involved in efforts to promote a cleaner environment by reducing both fuel consumption and emissions. For many years, our Asset-Based segment has voluntarily limited the maximum speed of its trucks, which reduces fuel consumption and emissions and contributes to ABF Freight’s excellent safety record. Our Asset-Based segment utilizes engine idle management programming to automatically shut down engines of parked tractors. Fuel consumption and emissions have also been minimized through a strict equipment maintenance schedule. In 2015, our Asset-Based segment began voluntarily installing aerodynamic aids on its fleet of over-the-road trailers to further enhance fuel economy and reduce emissions. ABF Freight participates in the EPA’s SmartWay Transport Partnership, a collaboration between the EPA and the freight transportation industry that helps freight shippers, carriers, and logistics companies reduce greenhouse gases and diesel emissions. ABF Freight was recognized with a 2018 SmartWay Freight Carrier Excellence Award by the EPA’s SmartWay Transport Partnership for being a top freight carrier for superior environmental performance and for its actions to reduce freight emissions. ABF Freight was also awarded a SmartWay Excellence Award in 2014 for industry leadership in freight supply chain environmental performance and energy efficiency. For the past nine years, ABF Freight has been recognized in Inbound Logistics’ annual list of supply chain partners committed to sustainability. Furthermore, in association with the American Trucking Associations’ Sustainability Task Force, ABF Freight has participated in other opportunities to address environmental issues.

All reports and financial information filed with, or furnished to, the SEC can be obtained, free of charge, through our website located at arcb.com or through the SEC’s website located at sec.gov as soon as reasonably practical after such material is electronically filed with, or furnished to, the SEC. The information contained on our website does not constitute part of this Annual Report on Form 10-K nor shall it be deemed incorporated by reference into this Annual Report on Form 10‑K.

ITEM 1A.RISK FACTORS

The nature of the business activities we conduct subjects us to certain hazards and risks. This Risk Factors section discusses some of the material risks relating to our business activities, including business risks affecting the transportation industry in general, as well as risks specific to our Company that are largely out of our control. Other risks are described in “Competition, Pricing, and Industry Factors” within Part I, Item 1 (Business) and in Part II, Item 7A (Quantitative and Qualitative Disclosures About Market Risk) of this Annual Report on Form 10-K. These risks are not the only risks we face. We may also be negatively impacted by a sustained interruption in our systems or operations, including, but not limited to, infrastructure damage, the loss of a key location such as a distribution center, or a significant disruption to the electric grid, or by a significant decline in demand for our services, each of which may arise from adverse weather conditions or natural calamities; illegal acts, including terrorist attacks; changes in the social, political, and regulatory conditions in the United States; and/or other market disruptions. We could also be affected by additional risks and uncertainties not currently known to us or that we currently deem to be immaterial. If any of these risks or circumstances actually occur, it could materially harm our business, results of operations, financial condition, and cash flows and impair our ability to implement business plans or complete development activities as scheduled. In such cases, the market price of our common stock could decline.

We are dependent on our information technology systems, and a systems failure or cybersecurity incident could have a material adverse effect on our business, results of operations, and financial condition.

We depend on the proper functioning, availability and security of our information systems, including communications, data processing, financial, and operating systems, as well as proprietary software programs that are integral to the efficient operation of our business. Our information technology systems are vulnerable to interruption by adverse weather conditions or natural calamities, power loss, telecommunications failures, terrorist attacks, internet failures, computer viruses, and other events beyond our control.  Any significant failure or other disruption in our critical information systems, including cybersecurity attacks and other cyber incidents, that impact the availability, reliability, speed, accuracy, or other proper functioning of these systems or that result in proprietary information or sensitive or confidential data, including personal information of customers, employees and others, being compromised could have a significant impact on our operations. Any new or enhanced technology that we may develop and implement may also be subject to cybersecurity attacks and may be more prone to related incidents. We also utilize certain software applications provided by third parties and provide underlying data which is utilized by third parties who provide certain outsourced administrative functions, either of which may increase the risk of a cybersecurity incident. Any problems caused by or impacting these third parties, including cyber attacks and security breaches at a vendor, could adversely affect our ability to provide service to our customers and otherwise conduct our business. 

A significant disruption in our information technology systems or a significant cyber incident, including denial of service, system failure, security breach, intentional or inadvertent acts by employees or vendors with access to our systems or data, disruption by malware, or other damage, could interrupt or delay our operations, damage our reputation, cause a loss of customers, cause errors or delays in financial reporting, expose us to a risk of loss or litigation, and/or cause us to incur significant time and expense to remedy such an event, any of which could have a material adverse impact on our business, results of operations, and financial condition. We attempt to mitigate our exposure to these risks through our technology security programs and disaster recovery plans, but there can be no assurance that such measures will be effective. Our business interruption and cyber insurance would offset losses up to certain coverage limits in the event of a catastrophe or certain cyber incidents; however, losses arising from a catastrophe or significant cyber incident would likely exceed our insurance coverage and could have a material adverse impact on our results of operations and financial condition.

We have experienced incidents involving attempted denial of service attacks, malware attacks, and other events intended to disrupt information systems, wrongfully obtain valuable information, or cause other types of malicious events that could have resulted in harm to our business. To date, the systems employed have been effective in identifying these types of events at a point when the impact on our business could be minimized. We must continuously monitor and develop our information technology networks and infrastructure to prevent, detect, address, and mitigate the risk of unauthorized access, misuse, computer viruses, and other events that could have a security impact.  Despite our efforts, due to the increasing sophistication of cyber criminals and the development of new techniques for attack, we may be unable to anticipate or promptly detect, or implement adequate protective or remedial measures against, the activities of perpetrators of cyber attacks.

We engage third parties to provide certain information technology needs, including licensed software, and the inability to maintain these third-party systems or licenses, or any interruptions or failures thereof, could adversely affect our business.

Certain information technology needs are provided by third parties, and we have limited control over the operation, quality, or maintenance of services provided by our vendors or whether they will continue to provide services that are essential to our business. The efficient and uninterrupted operation of our information technology systems depends upon the internet, electric utility providers, and telecommunications providers (terrestrial, cellular and satellite); and the information technology systems of our third-party service providers are vulnerable to interruption by adverse weather conditions or natural calamities, power loss, telecommunications failures, terrorist attacks, internet failures, computer viruses, and other events beyond our control. Disruptions or failures in the services upon which our information technology platforms rely, or in other services provided to us by outside service providers upon which we rely to operate our business and report financial results, may adversely affect our operations and the services we provide, which could increase our costs or result in a loss of customers that could have a material adverse effect on our results of operations and financial condition. Additionally, we license a variety of software that supports our operations, and these operations depend on our ability to maintain these licenses. We have no guarantees that we will be able to continue these licensing arrangements with the current licensors, or that we can replace the functions provided by these licenses, on commercially reasonable terms or at all.

If we are unable to timely and effectively develop and implement new or enhanced technology, we may suffer competitive disadvantage, loss of customers or other consequences that could negatively impact our business, results of operations and financial condition.

The industry has experienced rapid changes in technology, including the development of new technology and enhancements in existing technology. As technology improves, our customers may be able to find alternatives to our services to meet their freight transportation and logistics needs.  New entrants to the market, including start-ups and emerging technologies such as digital freight exchanges, have also expanded the field of competition and driven an increased pressure for innovation in the industry. 

Technology and new market entrants may also disrupt the way we, and our competitors, operate to provide freight logistics services.  We expect our customers to continue to demand more sophisticated technology-driven solutions from their suppliers, and we believe that we must respond by investing in the enhancement of existing technology and in the development of new and innovative solutions to improve efficiencies and meet our customers’ needs.  We have made, and continue to make, significant investments in software and physical assets that are in various stages of development and implementation.  Our efforts and investments in technology innovation may require significant ongoing research and development costs and implementation costs, and may involve potential unforeseen challenges and new or unforeseen risks associated with the technology.  The success of our approach to technology innovation is dependent upon market acceptance of our solutions and a number of other factors, including our ability to:

If we fail to successfully develop and deploy enhanced or new technology, we may be placed at a competitive disadvantage, lose customers, incur higher than anticipated costs, including the possible impact of asset impairment, or fail to meet the goals of our internal growth strategy, any one of which could materially adversely impact our financial condition and results of operations.

The loss or reduction in business from one or more large customers, or an overall reduction in our customer base, could have a material adverse effect on our business, results of operations, financial condition, and cash flows.

Although we do not have a significant customer concentration, the growth of our business could be materially impacted and our results of operations and cash flows would be adversely affected if we were to lose all or a portion of the business of some of our large customers because they: choose to divert all or a portion of their business with us to one of our competitors; demand pricing concessions for our services; require us to provide enhanced services that increase our costs; or develop their own shipping and distribution capabilities.  Our customer relationships are generally not subject to long-term contractual obligations or minimum volume commitments, and we cannot ensure that our current customer relationships will continue at the same business levels or at all. 

A reduction in our customer base or difficulty in collecting, or the inability to collect, payments from our customers due to changes in pricing or other competitive factors could have a material adverse effect on our business, results of operations, financial condition, and cash flows.

We operate in a highly competitive and fragmented industry, and our business could suffer if we are unable to adequately address downward pricing pressures and other factors that could adversely affect our profitability, growth prospects, and ability to compete in the transportation industry.

We face significant competition in local, regional, national, and, to a lesser extent, international markets. We compete with LTL carriers of varying sizes, including both union and nonunion LTL carriers and, to a lesser extent, with truckload carriers and railroads. We also compete with domestic and global logistics service providers, including asset-light logistics companies, integrated logistics companies, and third-party freight brokers, which compete in one or more segments of the transportation industry. Numerous factors could adversely impact our ability to compete effectively in the transportation and logistics industry, retain our existing customers, or attract new customers, which could have a material adverse effect on our business, results of operations, financial condition, and cash flows. These competitive factors include, but are not limited to, the following:

We depend on our employees to support our business operations and future growth opportunities. If our relationship with our employees deteriorates, if we have difficulty attracting and retaining employees, or if our Asset-Based segment is unable to reach agreement on future collective bargaining agreements, we could be faced with labor inefficiencies, disruptions, or stoppages, or delayed growth, which could have a material adverse effect on our business, results of operations, financial condition, and cash flows.

As of December 2018, approximately 82% of our Asset-Based segment’s employees were covered under the 2018 ABF NMFA, the collective bargaining agreement with the IBT which will remain in effect through June 30, 2023. If we are unable to effectively manage our relationship with the IBT, we could be less effective in ongoing relations and future negotiations, which could lead to operational inefficiencies and increased operating costs. The terms of any future collective bargaining agreements or the inability to agree on acceptable terms for the next contract period may also result in higher labor costs, insufficient operational flexibility which may increase our operating costs, a work stoppage, the loss of customers, or other events that could have a material adverse effect on our business, results of operations, financial condition, and cash flows. We could also experience a loss of customers or a reduction in our potential share of business in the markets we serve if shippers limit their use of unionized freight transportation service providers because of the risk of work stoppages.

With the exception of certain geographic markets, we have not historically experienced significant long-term difficulty in attracting or retaining qualified drivers, technicians and freight-handling personnel for our Asset-Based operations, although short-term difficulties have been encountered in certain situations, such as periods of significant increases in tonnage or shipment levels. Additionally, the available pool of drivers and technicians has been declining, which may cause us difficulty in retaining and hiring qualified drivers and other personnel. Both our profitability and our ability to grow could be adversely affected if we encounter difficulty in attracting and retaining qualified drivers, technicians and freight-handling personnel or if we become subject to contractually required increases in compensation or fringe benefit costs. Government regulations or the adverse impact of certain legislative actions that result in shortages of qualified drivers could also impact our ability to grow the Company. If we are unable to continue to attract and retain qualified drivers, we could incur higher driver recruiting expenses or a loss of business.

Our ability to maintain and grow our business will also depend, in part, on our ability to retain and attract additional sales representatives and other key operational personnel and properly incentivize them to obtain new customers, maintain existing customer relationships, and efficiently manage our business. If we are unable to maintain or expand our sales and operational workforce, our ability to increase our revenues and operate our business could be negatively impacted.

Our initiatives to grow our business operations or to manage our cost structure to business levels may take longer than anticipated or may not be successful.

Developing service offerings requires ongoing investment in personnel and infrastructure, including operating and management information systems. Depending upon the timing and level of revenues generated from our growth initiatives, the related results of operations and cash flows we anticipate from these initiatives and additional service offerings may not be achieved. If we are unable to manage our growth effectively, our business, results of operations, and financial condition may be adversely affected.

Our growth plans place significant demands on our management and operating personnel and we may not be able to hire, train, and retain the appropriate personnel to manage and grow these services. Hiring new employees may increase training costs and may result in temporary labor inefficiencies. In addition, as we focus on growing the business in our ArcBest segment, we may encounter difficulties in adapting our corporate structure or in developing and maintaining effective partnerships among our operating segments, which could hinder our operational, financial, and strategic objectives. Furthermore, we may invest significant resources to enter or expand our services in markets with established competitors and in which we will encounter new competitive challenges, and we may not be able to successfully gain market share, which could have an adverse effect on our operating results and financial condition.

We also face challenges and risks in implementing initiatives to manage our cost structure to business levels, as portions of salaries, wages, and benefits are fixed in nature and the adjustments which would otherwise be necessary to align the labor cost structure to corresponding business levels are limited as we strive to maintain customer service. We may not be able to appropriately adjust our cost structure to changing market demands. It is more difficult to match our staffing levels to our business needs in periods of rapid or unexpected change. We may incur additional costs related to purchased transportation and/or experience labor inefficiencies while, and for a time following, training employees who are hired in response to growth. These costs of managing our cost structure could have a material adverse effect on our results of operations and financial condition. We periodically evaluate and modify the network of our Asset-Based operations to reflect changes in customer demands and to reconcile the segment’s infrastructure with tonnage levels and the proximity of customer freight, and there can be no assurance that these network changes, to the extent such network changes are made, will result in a material improvement in our Asset-Based segment’s results of operations.

Our business is cyclical in nature, and we are subject to general economic factors and instability in financial and credit markets that are largely beyond our control, any of which could adversely affect our business, financial condition, and results of operations.

Our business is cyclical in nature and tends to reflect general economic conditions, which can be impacted by government actions, including suspension of government operations. Our performance is affected by recessionary economic cycles, downturns in customers’ business cycles, and changes in their business practices. Our tonnage and shipment levels are directly affected by industrial production and manufacturing, distribution, residential and commercial construction, and consumer spending, in each case primarily in the North American economy, and capacity in the trucking industry as well as our customers’ inventory levels and freight profile characteristics. We are also subject to risks related to disruption of world markets that could affect shipments between countries and could adversely affect the volume of freight in the markets we serve and related pricing. Recessionary economic conditions may result in a general decline in demand for freight transportation and logistics services. The pricing environment generally becomes more competitive during periods of slow economic growth and economic recessions, which adversely affects the profit margin for our services. Our operations and the rates we obtain for our services may also be negatively impacted when economic conditions lead to a decrease in shipping demand, which in turn results in excess tractor and trailer capacity in the industry. In certain market conditions, we may have to accept more freight from freight brokers, where freight rates are typically lower, or we may be forced to incur more non-revenue miles to obtain loads.

Economic conditions could adversely affect our customers’ business levels, the amount of transportation services they require, and their ability to pay for our services, thus negatively impacting our working capital and our ability to satisfy our financial obligations and covenants of our financing arrangements. Because a portion of our costs are fixed, it may be difficult for us to quickly adjust our cost structure proportionately with fluctuations in volume levels. Customers encountering adverse economic conditions or facing credit issues could experience cash flow difficulties and, thus, represent a greater potential for payment delays or uncollectible accounts receivable, and, as a result, we may be required to increase our allowances for uncollectible accounts receivable. Our obligation to pay third-party service providers is not contingent upon payment from our customers, and we extend credit to certain of these customers which increases our exposure to uncollectible receivables.

Given the economic conditions of recent years, current economic uncertainties, and the potential impact on our business, there can be no assurance that our estimates and assumptions regarding the pricing environment and economic conditions, which are made for purposes of impairment tests related to operating assets and deferred tax assets, will prove to be accurate.

We are affected by the instability in the financial and credit markets that from time to time has created volatility in various interest rates and returns on invested assets in recent years. We are subject to market risk due to variable interest rates on our borrowings on the accounts receivable securitization program and the revolving credit facility (“Credit Facility”). Although we have an interest rate swap agreement to mitigate a portion of our interest rate risk by effectively converting $50.0 million of borrowings under our Credit Facility, of which $70.0 million remains outstanding at the end of February 2019, from variable-rate interest to fixed-rate interest, changes in interest rates may increase our financing costs related to our Credit Facility, future borrowings against our accounts receivable securitization program, new notes payable or capital lease arrangements, or additional sources of financing. Interest rates are highly sensitive to many factors, including governmental monetary policies, domestic and international economic and political conditions and other factors beyond our control. Furthermore, future financial market disruptions may adversely affect our ability to refinance our Credit Facility and accounts receivable securitization program, maintain our letter of credit arrangements or, if needed, secure alternative sources of financing. If any of the financial institutions that have extended credit commitments to us are adversely affected by economic conditions, disruption to the capital and credit markets, or increased regulation, they may become unable to fund borrowings under their credit commitments or otherwise fulfill their obligations to us, which could have an adverse impact on our ability to borrow additional funds, and thus have an adverse effect on our operations and financial condition. (See Note G to our consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K for further discussion of our financing arrangements.)

As of December 31, 2018, our qualified nonunion defined benefit pension plan trust held investments in cash equivalents and income securities totaling $26.6 million, which are reported at fair value based on quoted market prices and are subject to market risk. Although these investments were primarily held in money market mutual funds as of December 31, 2018, declines in the value of plan assets resulting from instability in the financial markets, general economic downturn, or other economic factors beyond our control could cause a decline in the funded status of the nonunion defined benefit pension plan and potentially require an increase in the contribution we may be required to make to fund the purchase of a nonparticipating annuity contract to settle the remaining obligation for plan benefits in excess of plan assets upon liquidation of the plan in first quarter 2019. (See Note I to our consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K for further discussion of termination of our nonunion defined benefit pension plan.)

We could also experience losses on investments related to our cash surrender value of variable life insurance policies, which may negatively impact our results of operations.

Furthermore, it is not possible to predict the effects of actual or threatened armed conflicts, terrorist attacks, or political and/or civil unrest on the economy or on consumer confidence in the United States or the impact, if any, on our future results of operations or financial condition.

We depend on services provided by third parties, and increased costs or disruption of these services, and claims arising from these services, could adversely affect our business, results of operations, financial condition, cash flows, and customer relationships.

A reduction in the availability of rail services or services provided by third-party capacity providers to meet customer requirements, as well as higher utilization of third-party agents to maintain service levels in periods of tonnage growth or higher shipment levels, could increase purchased transportation costs which we may be unable to pass along to our

customers. If a disruption or reduction in transportation services from our rail or other third-party service providers were to occur, we could be faced with business interruptions that could cause us to fail to meet the needs of our customers. In addition, we may not be able to negotiate competitive contracts with railroads or other third-party service providers to expand our capacity, add additional routes, or obtain services at costs that are acceptable to us or our customers. If these situations occur, our business, results of operations, financial condition, cash flows, and customer relationships could be adversely impacted.

Our ability to secure the services of third-party service providers is affected by many risks beyond our control, including the inability to obtain the services of reliable third parties at competitive prices; the shortage of quality third-party providers, including owner operators and drivers of contracted carriers for our ArcBest segment; shortages in available cargo capacity of third parties, including capacity constraints in the truckload market which we experienced during 2018; equipment shortages in the transportation industry, particularly among contracted truckload carriers; changes in government regulations affecting the transportation industry and their related impact on operations, such as hours-of-service rules and the ELD mandate discussed in “Competition, Pricing, and Industry Factors” within Part I, Item 1 (Business) of this Annual Report on Form 10-K; labor disputes; or a significant interruption in service or stoppage in third-party transportation services. Each of these risks could have a material adverse effect on the operating results of our ArcBest segment.

Third-party providers can be expected to increase their prices based on market conditions or to cover increases in operating expenses. These providers are subject to industry regulations which may have a significant impact on their operations, causing them to increase prices or exit the industry. Increased industry demand for these transportation services may reduce available capacity and such a reduction or other changes in these services offered by third parties may increase pricing or otherwise change the services we are able to offer to our customers. If we are unable to correspondingly increase the prices we charge to our customers, including the effect of third-party carrier rate increases outpacing customer pricing, or if we are unable to secure sufficient third-party services to meet our commitments to our customers, there could be a material adverse impact on our operations, revenues, profitability and customer relationships.

In addition, we may be subject to claims arising from services provided by third parties, particularly in connection with the operations of our ArcBest segment, which are dependent on third-party contract carriers. From time to time, the drivers who are owner operators, independent contractors, or employees working for third-party carriers that we contract with are involved in accidents or incidents that may result in cargo loss or damage, other property damage, or serious personal injuries including death. As a result, claims may be asserted against us for actions by such drivers or for our actions in contracting with them initially or retaining them over time. The Company or its subsidiaries could be held directly responsible for these third-party claims and, regardless of ultimate liability, may incur significant costs and expenses in defending these claims. We may also incur claims in connection with third-party vendors utilized in FleetNet’s operations. Our third-party contract carriers and other vendors may not agree to bear responsibility for such claims or we may become responsible if they are unable to pay the claims, for example, due to bankruptcy proceedings, and such claims may exceed the amount of our insurance coverage or may not be covered by insurance at all.

Our business operations are subject to numerous governmental regulations, and costs of compliance with, or liability for violations of, existing or future regulations could have a material adverse effect on our financial condition and results of operations.

Various federal and state agencies exercise broad regulatory powers over the transportation industry, generally governing such activities as operations of and authorization to engage in motor carrier freight transportation, operations of non-vessel-operating common carriers, operations of ocean freight forwarders and ocean transportation intermediaries, indirect air carriage, safety, contract compliance, insurance and bonding requirements, tariff and trade policies, customs, import and export, food safety, employment practices, licensing and registration, taxation, environmental matters, data privacy and security, and financial reporting. We could become subject to new or more restrictive regulations, such as regulations relating to engine emissions, drivers’ hours of service, occupational safety and health, ergonomics, or cargo security. Increases in costs to comply with such regulations or the failure to comply, which could subject us to penalties or revocation of our permits or licenses, could increase our operating expenses or otherwise have a material adverse effect on the results of our operations. Such regulations could also influence the demand for transportation services.  Failure to comply with safety and security laws and regulations can result in both civil and criminal actions against the Company.  In addition to the potential harm to our reputation and brands, the financial burdens resulting from such actions could have a material adverse effect on our financial condition and results of operations.

We operate in the United States, and from the United States for international transportation, pursuant to federal operating authority granted by the DOT, the U.S. Federal Maritime Commission and the Transportation Security Administration, which is now part of the U.S. Department of Homeland Security. Failures by us, or our contracted owner operators and third-party carriers, to comply with the various applicable federal safety laws and regulations, or downgrades in our safety rating, could have a material adverse impact on our operations or financial condition. A downgrade in our safety rating could cause us to lose customers, as well as the ability to self-insure. The loss of our ability to self-insure for any significant period of time could materially increase insurance costs or we could experience difficulty in obtaining adequate levels of insurance coverage.

Our ArcBest segment utilizes third-party service providers who are subject to similar regulation requirements, as previously mentioned. If the operations of these providers are impacted to the extent that a shortage of quality third-party service providers occurs, there could be a material adverse effect on our ArcBest segment’s business and results of operations. Also, activities by these providers that violate applicable laws or regulations could result in governmental or third-party actions against us. Although third-party service providers with whom we contract agree to comply with applicable laws and regulations, we may not be aware of, and may therefore be unable to address or remedy, violations by them.

As a worldwide transportation and logistics provider, the Company collects and processes significant amounts of customer data on a daily basis. Recently, there have been global efforts by governments and consumer groups for increased transparency in how customer data is utilized and how customers can control the use and storage of their data. In 2018, the European Union's General Data Protection Regulation (“GDPR”) went into effect, which imposes strict new rules on controlling and processing customer data originating from the European Union. The State of California also passed an extensive consumer data protection law. Complying with new data protection laws and regulations, including the GDPR and the California Consumer Privacy Act of 2018, may increase the Company’s compliance costs or require us to modify our data handling practices. Non-compliance could result in governmental or consumer actions against us and may otherwise adversely impact our reputation, operating results and financial condition.

Our operations are subject to various environmental laws and regulations, the violation of which could result in substantial fines or penalties. The costs of compliance with existing and future environmental laws and regulations may be significant and could adversely impact our results of operations.

We are subject to federal, state and local environmental laws and regulations relating to, among other areas: emission controls, transportation of hazardous materials, underground and aboveground storage tanks, stormwater pollution prevention, contingency planning for spills of petroleum products, and disposal of waste oil. We may be subject to substantial fines or civil penalties if we fail to obtain proper certifications or permits or if we do not comply with required inspections and testing provisions.

We routinely transport or arrange for the transportation of hazardous materials and explosives. These operations involve the risks of, among others, fuel spillage or leakage, environmental damage, a spill or accident involving hazardous substances, and hazardous waste disposal.  In addition, if any damage or injury occurs as a result of our transportation of hazardous materials or explosives, we may be subject to claims from third parties and bear liability for such damage or injury.

At certain facilities of our Asset-Based operations, we store fuel and oil in underground and aboveground tanks.  Our material handling and storage, fueling, equipment maintenance and cleaning subject us to the Clean Water Act stormwater regulations.   With regard to these areas, applicable regulatory requirements have several components including training, notification, inspection, testing, and operations and maintenance.

Under certain environmental laws, we could be subject to strict liability for any clean-up costs relating to contamination at our past or present facilities and at third-party waste disposal sites, as well as costs associated with the cleanup of accidents involving our vehicles.

Although we have instituted programs to monitor and control environmental risks and promote compliance with applicable environmental laws and regulations, violations of applicable laws or regulations may subject us to cleanup costs and liabilities not covered by insurance or in excess of our applicable insurance coverage, including substantial fines, civil penalties, or civil and criminal liability, as well as bans on making future shipments in particular geographic areas, any of which could adversely affect our business, results of operations, financial condition, and cash flows.

Concern over climate change, including the impact of global warming, has led to significant legislative and regulatory efforts to limit carbon and other greenhouse gas emissions, and some form of federal, state, and/or regional climate change legislation is possible in the future, including the CTI which includes plans for future rulemaking to reduce NOx emissions. We are unable to determine with any certainty the effects of any future climate change legislation. However, emission-related regulatory actions have historically resulted in increased costs of revenue equipment, diesel fuel, and equipment maintenance, and future legislation, if enacted, could impose substantial costs on us that may adversely impact our results of operations. Such regulatory actions have also required vendors to introduce new engines and emissions technologies, and the maintenance demands and reliability of vehicles equipped with these newly designed engines, as well as the residual values realized from the disposition of these vehicles, is uncertain. Such regulatory actions may also require changes in our operating practices and impair equipment productivity. We are also subject to increasing customer sensitivity to sustainability issues, and we may be subject to additional requirements related to customer-led initiatives or their efforts to comply with environmental programs. Until the timing, scope, and extent of any future regulation or customer requirements become known, we cannot predict their effect on our cost structure, business, or results of operations. Furthermore, although we are committed to mandatory and voluntary sustainability practices, increased awareness and any adverse publicity about greenhouse gas emissions emitted by companies in the transportation industry could harm our reputation or reduce customer demand for our services.

We could be obligated to make additional significant contributions to multiemployer pension plans.

ABF Freight contributes to multiemployer pension and health and welfare plans to provide benefits for its contractual employees. ABF Freight’s contributions generally are based on the time worked by its contractual employees in accordance with its collective bargaining agreement with the IBT and other related supplemental agreements.

The multiemployer plans to which ABF Freight contributes, which have been established pursuant to the Taft-Hartley Act, are jointly-trusteed (half of the trustees of each plan are selected by the participating employers, the other half by the IBT) and cover collectively-bargained employees of multiple unrelated employers. Due to the inherent nature of multiemployer pension plans, there are risks associated with participation in these plans that differ from single-employer plans. Assets received by the plans are not segregated by employer, and contributions made by one employer can be and are used to provide benefits to current and former employees of other employers. If a participating employer in a multiemployer pension plan no longer contributes to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers. If a participating employer in a multiemployer pension plan completely withdraws from the plan, it owes to the plan its proportionate share of the plan’s unfunded vested benefits, referred to as a withdrawal liability. A complete withdrawal generally occurs when the employer permanently ceases to have an obligation to contribute to the plan. Withdrawal liability is also owed in the event the employer withdraws from a plan in connection with a mass withdrawal, which generally occurs when all or substantially all employers withdraw from the plan in a relatively short period of time pursuant to an agreement. Were ABF Freight to completely withdraw from certain multiemployer pension plans, whether in connection with a mass withdrawal or otherwise, under current law, we would have material liabilities for our share of the unfunded vested liabilities of each such plan.

The 25 multiemployer pension plans to which ABF Freight contributes vary greatly in size and in funded status. ABF Freight’s obligations to these plans are generally specified in the 2018 ABF NMFA, which will remain in effect through June 30, 2023. The funding obligations to the multiemployer pension plans are intended to satisfy the requirements imposed by the Pension Protection Act of 2016 (the “PPA”), which was permanently extended by the Reform Act under the CFCAA. ABF Freight pays some of the highest benefit contribution rates in the industry and continues to address the effect of the Asset-Based segment’s wage and benefit cost structure on its operating results in discussions with the IBT. Through the term of its current collective bargaining agreement, ABF Freight’s obligations generally will be satisfied by making the specified contributions when due. Future contribution rates will be determined through the negotiation process for contract periods following the term of the current collective bargaining agreement.  We cannot determine with any certainty the minimum contributions that will be required under future collective bargaining agreements or the impact they will have on our results of operations and financial condition.

Several of the multiemployer pension plans to which ABF Freight contributes are underfunded and, in some cases, significantly underfunded. The underfunded status of these plans developed over many years, and we believe that an improved funded status will also take time to be achieved, if it can be achieved at all. In addition, the highly competitive industry in which we operate could impact the viability of contributing employers. The reduction or loss of contributions by member employers, the impact of market risk or instability in the financial markets on plan assets and liabilities, and

the effect of any one or combination of the aforementioned business risks, all of which are beyond our control, have the potential to adversely affect the funded status of the multiemployer pension plans, potential withdrawal liabilities, and our future contribution requirements.

Based on the most recent annual funding notices we have received, most of which are for plan years ended December 31, 2017, approximately 62% of ABF Freight’s contributions to multiemployer pension plans are made to plans that are in “critical and declining status”, including the Central States, Southeast and Southwest Areas Pension Plan (the “Central States Pension Plan”) and the New England Teamsters and Trucking Industry Pension Fund (the “New England Pension Fund”). “Critical and declining status” is applicable to critical status plans under the PPA that are projected to become insolvent anytime within the next 14 plan years, or if the plan is projected to become insolvent within the next 19 plan years and either the plan’s ratio of inactive participants to active participants exceeds two to one or the plan’s funded percentage is less than 80%. Approximately 2% of ABF Freight’s contributions to multiemployer pension plans are made to plans that are in “critical status” (generally less than 65% funded) but not in “critical and declining status” and approximately 4% of its contributions are made to plans that are in “endangered status” (generally more than 65% but less than 80% funded), as defined by the PPA.

Approximately one-half of ABF Freight’s multiemployer pension contributions are made to the Central States Pension Plan. The funded percentage of the Central States Pension Plan, as set forth in information provided by the Central States Pension Plan, was 37.8% and 42.1% as of January 1, 2017 and 2016, respectively. ABF Freight received an Actuarial Certification of Plan Status for the Central States Pension Plan dated March 30, 2018, in which the plan’s actuary certified that, as of January 1, 2018, the plan is in critical and declining status, as defined by the Reform Act.  Although the future of the Central States Pension Plan is impacted by a number of factors, without legislative action, the plan is currently projected to become insolvent within 10 years or less. The 2018 ABF NMFA provides for contributions to the Central States Pension Plan through June 30, 2023, and ABF Freight’s contribution rate is not expected to increase during the remainder of this period (though there are no guarantees).

Our engagement of independent contractor drivers to provide a portion of the capacity for our ArcBest segment exposes us to different risks than we face with our employee drivers. If we have difficulty in securing independent owner operators, or if we incur increased costs to utilize independent owner operators, our financial condition, results of operations, and cash flows could be adversely affected.

The driver fleet for portions of our ArcBest segment is made up of independent owner operators and individuals. We face intense competition in attracting and retaining qualified owner operators from the available pool of drivers and fleets, and we may be required to increase owner operator compensation or take other measures to remain an attractive option for owner operators, which may negatively impact our results of operations. If we are not able to maintain our delivery schedules due to a shortage of drivers or if we are required to increase our rates to offset increases in owner operator compensation, our services may be less competitive, which could have an adverse effect on our business. Furthermore, as these independent owner operators and individuals are third-party service providers, rather than our employees, they may decline loads of freight from time to time, which may impede our ability to deliver freight in a timely manner. If we fail to meet certain customer needs or incur increased expenses to do so, this could adversely affect the business, financial condition, and results of operations of our ArcBest segment.

Additionally, we pay independent contractor drivers a fuel surcharge that increases with the increase in fuel prices. A significant increase or rapid fluctuation in fuel prices could cause the fuel surcharge we pay to independent contractors to be higher than the revenue we receive under our customer fuel surcharge programs, which could adversely impact the results of operations of our ArcBest segment.

If the independent contractors we contract with are deemed by regulators or judicial process to be employees, or if we experience operational or regulatory issues related to our use of these contract drivers, our financial condition, results of operations, and cash flows could be adversely affected.

The transportation and logistics industry’s heavy dependence on independent contractors for providing services has made it a target of litigation. Class actions and other lawsuits have arisen in the industry seeking to reclassify independent contractor drivers as employees for a variety of purposes, including workers’ compensation, wage-and-hour, and health care coverage. Many states have enacted restrictive laws that make it difficult to successfully prove independent-contractor status, and all states have enforcement programs to evaluate the classification of independent contractors.  There can be no assurance that legislative, judicial, or regulatory authorities will not introduce proposals or assert interpretations of

existing rules and regulations resulting in the reclassification of the owner operators of the operations within our ArcBest segment as employees. In the event of such reclassification of these owner operators, we could be exposed to various liabilities and additional costs and our business and results of operations could be adversely affected. These liabilities and additional costs could include exposure, for both future and prior periods, under federal, state, and local tax laws, and workers’ compensation, unemployment benefits, labor, and employment laws, as well as potential liability for penalties and interest and under vicarious liability principles, which could have a material adverse effect on the results of operations and financial condition of our ArcBest segment.

We are subject to litigation risks that could result in significant expenditures and have other material adverse effects on our business, results of operations, and financial condition.

The nature of our business exposes us to the potential for various claims and litigation, including class-action litigation and other legal proceedings brought by customers, suppliers, employees, or other parties, related to labor and employment, competitive matters, personal injury, property damage, cargo claims, safety and contract compliance, environmental liability, and other matters. We are subject to risk and uncertainties related to liabilities, including damages, fines, penalties, and substantial legal and related costs, that may result from these claims and litigation. Some or all of our expenditures to defend, settle, or litigate these matters may not be covered by insurance or could impact our cost of, and ability to obtain, insurance in the future. Also, litigation can be disruptive to normal business operations and could require a substantial amount of time and effort by our management team.  Any material litigation or a catastrophic accident or series of accidents could have a material adverse effect on our business, results of operations, and financial condition. Our business reputation and our relationship with our customers, suppliers, and employees may also be adversely impacted by our involvement in legal proceedings.

We establish reserves based on our assessment of known legal matters and contingencies. New legal claims, or subsequent developments related to known legal claims, asserted against us may affect our assessment and estimates of our recorded legal reserves and may require us to make payments in excess of our reserves, which could have an adverse effect on our financial condition or results of operations.

Our corporate reputation and our business depend on a variety of intellectual property rights, including trademarks, domain names, trade secrets, copyrights, patents, and licenses and other contractual rights.  If we are unable to maintain our corporate reputation, our brands, and other intellectual property rights, or if we face claims of infringement of third-party rights, our business may suffer.  The costs and resources expended to enforce or protect our rights or to defend against infringement claims could adversely impact our business, results of operations, and financial condition.

ArcBest is recognized as a multi-faceted logistics provider with creative problem solvers who deliver integrated logistics solutions. Beyond this fundamental marketplace recognition of our collective brand identity, our other key brands represent additional unique value in their target markets. The ABF Freight brand is well-recognized in the industry for our Asset-Based operations’ leadership in commitment to quality, customer service, safety, and technology. The Panther Premium Logistics brand within the operations of our ArcBest segment is recognized for solving the toughest shipping and logistics challenges, delivering time-sensitive, mission-critical, and high-value freight with speed and precision. Our business depends, in part, on our ability to maintain the image of our brands. Service, performance, and safety issues, whether actual or perceived and whether as a result of our actions or those of our third-party contract carriers and their drivers and owner operators or other third-party service providers, could adversely impact our customers’ image of our brands, including ArcBest, ABF Freight, Panther Premium Logistics, and U‑Pack, and result in the loss of business or impede our growth initiatives. Adverse publicity regarding labor relations, legal matters, environmental concerns, and similar matters, whether or not justified, could have a negative impact on our reputation and may result in the loss of customers and our inability to secure new customer relationships. Our business and our image could also be negatively impacted by a breach of our corporate policies by employees or vendors. Portions of our business, such as the moving services provided under our U-Pack brand, are dependent on the internet for attracting and securing customers, and the possibility that fraudulent behavior may confuse or deceive customers heightens the risk of damage to our reputation and increases the time and expense required to protect and maintain the integrity of our brands.  With the increased use of social media outlets, adverse publicity can be disseminated quickly and broadly, making it increasingly difficult for us to effectively respond. Damage to our reputation and loss of brand equity could reduce demand for our services and thus have an adverse effect on our business, results of operations, and financial condition, as well as require additional resources to rebuild our reputation and restore the value of our brands.

We have registered or are pursuing registration of various marks and designs as trademarks in the United States, including but not limited to “ArcBest,” “ABF Freight,” “FleetNet America,” “Panther Premium Logistics,” “U-Pack,” “The Skill & The Will,” and “More Than Logistics.”  For some marks, we also have registered or are pursuing registration in certain other countries. At times, competitors may adopt service or trade names or logos or designs similar to ours, thereby impeding our ability to build brand identity and possibly leading to market confusion. In addition, there could be potential trade name or trademark infringement claims brought by owners of other registered trademarks or trademarks that incorporate variations of our registered trademarks. From time to time, we have acquired or attempted to acquire internet domain names held by others when such names have caused, or had the potential to cause, consumer confusion. Additionally, our business and operations utilize and depend upon both internally developed and purchased technology, either of which could be infringed upon, or subject to claims of infringement.  Any of our intellectual property rights related to trademarks, trade secrets, domain names, copyrights, patents, or other intellectual property, whether owned or licensed, could be challenged or invalidated, or misappropriated or infringed upon, by third parties. Our efforts to obtain, enforce, or protect our proprietary rights, or to defend against a third-party infringement claim, may be ineffective and could result in substantial costs and diversion of resources and could adversely impact our corporate reputation, business, results of operations, and financial condition.

Our management team is an important part of our business and loss of key employees could impair our business, results of operations, and financial condition.

We benefit from the leadership and experience of our senior management team and other key employees and depend on their continued services to successfully implement our business strategy. The unexpected loss of key employees or inability to execute our training and succession planning strategies could have an adverse effect on our business, results of operations, and financial condition if we are unable to secure replacement personnel that have sufficient experience in our industry and in the management of our business.

Our Credit Facility and accounts receivable securitization program contain customary financial covenants and other customary restrictive covenants that may limit our future operations. A default under these financing arrangements or changes in regulations which impact the availability of funds or our costs to borrow under our financing arrangements could cause a material adverse effect on our liquidity, financial condition, and results of operations.

Our Second Amended and Restated Credit Agreement (the “Credit Agreement”), which governs our Credit Facility, contains representations and warranties, conditions, and events of default that are customary for financings of this type including, but not limited to, a minimum interest coverage ratio, a maximum adjusted leverage ratio, and limitations on incurrence of debt, investments, liens on assets, certain sale and leaseback transactions, transactions with affiliates, mergers, consolidations, and sales of assets. Our accounts receivable securitization program also contains affirmative and negative covenants and events of default that are customary for financings of this type, including a maximum adjusted leverage ratio and requirements to maintain certain characteristics of the receivables, such as rates of delinquency, default, and dilution. Failing to achieve certain financial ratios as required by our Credit Facility and accounts receivable securitization program could adversely affect our ability to finance our operations, make strategic acquisitions or investments, or plan for or react to market conditions or otherwise execute our business strategies.

If we default under the terms of the Credit Agreement or our accounts receivable securitization program and fail to obtain appropriate amendments to or waivers under the applicable financing arrangement, our borrowings under such facilities could be immediately declared due and payable. An event of a default under either of these facilities could constitute automatic default on the other of these facilities and could trigger cross-default provisions in our outstanding notes payable and other financing agreements, unless the lenders to these facilities choose not to exercise remedies or to otherwise allow us to cure the default. If we fail to pay the amount due under our Credit Facility or accounts receivable securitization program, the lenders could proceed against the collateral by which the facility is secured, our borrowing capacity may be limited, or one or both of the facilities could be terminated. If acceleration of outstanding borrowings occurs or if one or both of the facilities is terminated, we may have difficulty borrowing additional funds sufficient to refinance the accelerated debt or entering into new credit or debt arrangements, and, if available, the terms of the financing may not be acceptable. A default under the Credit Agreement or accounts receivable securitization program, changes in regulations which impact the availability of funds or our costs to borrow under our financing arrangements, or our inability to renew our financing arrangements with terms that are acceptable to us, could have a material adverse effect on our liquidity and financial condition.

We have significant ongoing capital requirements that could have a material adverse effect on our business, profitability, and growth if we are unable to generate sufficient cash from operations or obtain sufficient financing on favorable terms or properly forecast capital needs to correspond with business volumes.

We have significant ongoing capital requirements. If we are not able to generate sufficient cash from operations in the future, our growth could be limited; it may be necessary for us to utilize our existing financing arrangements to a greater extent or enter into additional financing or leasing arrangements, possibly on less favorable terms; or our revenue equipment may have to be held for longer periods, which would result in increased expenditures for maintenance and reduced salvage value upon disposition of the assets. Forecasting business volumes involves many factors, including general economic trends and the impact of competition, which are subject to uncertainty and beyond our control. If we do not accurately forecast our future capital investment needs, especially for revenue equipment, in relation to corresponding business levels, we could have excess capacity or insufficient capacity. In addition, our Credit Facility contains provisions that could limit our level of annual capital expenditures. If we were unable to properly forecast capital needs and/or were unable to generate sufficient cash from operations, obtain adequate financing at acceptable terms, or if our capital spending was otherwise limited, there could be an adverse effect on our business, profitability, and growth.

Claims expenses or the cost of maintaining our insurance, including medical plans, could have a material adverse effect on our results of operations and financial condition.

Claims may be asserted against us for accidents or for cargo loss or damage, property damage, personal injury, and workers’ compensation related to events occurring in our operations. Claims may also be asserted against us for accidents involving the operations of third-party service providers that we utilize, for our actions in retaining their services, for loss or damage to our customers’ goods or other damages for which we are determined to be responsible. Such claims against us may not be covered by insurance policies or may exceed the amount of insurance coverage, which could adversely impact our results of operations and financial condition. While we have established liabilities which are adjusted to reflect our claims experience, actual claims costs and legal expenses may exceed our estimates. If the frequency and/or severity of claims increase, our operating results could be adversely affected. The timing of the incurrence of these costs could significantly and adversely impact our operating results.

We are primarily self-insured for workers’ compensation, third-party casualty loss, and cargo loss and damage claims for the operations of our Asset-Based segment and certain of our other subsidiaries. We also self-insure for medical benefits for our eligible nonunion personnel. Because we self-insure for a significant portion of our claims exposure and related expenses, our insurance and claims expense may be volatile. If we lose our ability to self-insure for any significant period of time, insurance costs could materially increase and we could experience difficulty in obtaining adequate levels of insurance coverage in that event. Our self-insurance program for third-party casualty claims is conducted under a federal program administered by a government agency. If the government were to terminate the program or if we were to be excluded from the program, our insurance costs could increase. Additionally, if our third-party insurance carriers or underwriters leave the trucking sector, our insurance costs or collateral requirements could materially increase, or we could experience difficulties in finding insurance in excess of our self-insured retention limits. We could also experience additional increases in our insurance premiums or deductibles in the future due to market conditions or if our claims experience worsens. If our insurance or claims expense increases, or if we decide to increase our insurance coverage in the future, and we are unable to offset any increase in expense with higher revenues, our earnings could be adversely affected. In some instances, certain insurance could become unavailable or available only for reduced amounts of coverage. If we were to incur a significant liability for which we were not fully insured, it could have a material adverse effect on our results of operations and financial condition.

Material increases in health care costs related to medical inflation, claims experience, current and future federal and state laws and regulations, and other cost components that are beyond our control could significantly increase the costs of our self-insured medical plans and postretirement medical costs, or require us to adjust the level of benefits offered to our employees. In particular, with the passage in 2010 of the U.S. Patient Protection and Affordable Care Act (the “PPACA”), we are required to provide health care benefits to all full-time employees that meet certain minimum requirements of coverage and affordability, or otherwise be subject to a payment per employee based on the affordability criteria set forth in the PPACA. The PPACA also requires individuals to obtain coverage or face individual penalties, so employees who are currently eligible but have elected not to participate in our health care plans may ultimately find it more advantageous to do so. In general, implementing the requirements of health care reform has imposed additional administrative costs. The costs of maintaining and monitoring compliance and reports and other effects of these new healthcare requirements, including any failure to comply, may significantly increase our health care coverage costs and could materially adversely

affect our financial condition and results of operations. Changes in healthcare legislation could potentially occur in the near term, which could result in changes to healthcare eligibility, design, and cost structure that could have an adverse impact on our business and operating costs; however, we cannot currently determine the impact of future regulatory action on our health care plans and the related costs.

We have programs in place with multiple surety companies for the issuance of unsecured surety bonds in support of our self-insurance program for workers’ compensation and third-party casualty liability. Estimates made by the states and the surety companies of our future exposure for our self-insurance liabilities could influence the amount and cost of additional letters of credit and surety bonds required to support our self-insurance program, and we may be required to maintain secured surety bonds in the future which could increase the amount of our cash equivalents and short-term investments restricted for use and unavailable for operational or capital requirements.

We may be unsuccessful in realizing all or any part of the anticipated benefits of any recent or future acquisitions.

As part of our long-term strategy to ensure we are positioned to serve our customers within the changing marketplace by providing a comprehensive suite of transportation and logistics services, we have strategically invested in our Asset-Light businesses through acquisitions, most recently in 2016 and 2015. We continue to evaluate acquisition candidates and may acquire assets and businesses that we believe complement our existing assets and business or enhance our service offerings. The processes of evaluating acquisitions and performing due diligence procedures include risks which may adversely impact the success of our selection of candidates, pricing of the transaction, and ability to integrate critical functional areas of the acquired business. Further, we may not be able to acquire any additional companies at all or on terms favorable to us, even though we may have incurred expenses in evaluating and pursuing the strategic transactions.

Acquisitions may require substantial capital or the incurrence of substantial indebtedness or may involve the dilutive issuance of equity securities. If we consummate any future acquisitions, our capitalization and results of operations may change significantly. We may be unable to generate sufficient revenue or earnings from the operation of an acquired business to offset our acquisition or investment costs, and the acquired business may otherwise fail to meet our operational or strategic expectations. The degree of success of our acquisitions will depend, in part, on our ability to realize anticipated cost savings and growth opportunities. Our success in realizing these benefits and the timing of this realization depends, in part, upon the successful integration of any acquired businesses.

The possible risks involved in acquisitions, including potential difficulties of integration include, among others:

The risks involved in successful integration could be heightened if we complete a large acquisition or multiple acquisitions within a short period of time. The diversion of management’s attention from our current operations to the acquired operations and any difficulties encountered in combining operations, including underestimation of the resources required to support the acquisitions, could prevent us from realizing the full benefits anticipated from the acquisitions, and within the anticipated timeframe, and could adversely impact our business, results of operations, and financial condition. If acquired operations fail to generate sufficient cash flows, we may incur impairments of goodwill, intangibles, and other assets in the future.

We depend heavily on the availability of fuel for our trucks. Fuel shortages, changes in fuel prices, and the inability to collect fuel surcharges could have a material adverse effect on our business, results of operations, financial condition, and cash flows.

The transportation industry is dependent upon the availability of adequate fuel supplies. A disruption in our fuel supply resulting from natural or man-made disasters; armed conflicts; terrorist attacks; actions by producers, including a decrease in drilling activity or the use of crude oil and oil reserves for purposes other than fuel production; legislation or regulations that require or result in new or alternate uses or other increase in the demand for fuel traditionally used by trucks; or other political, economic, and market factors that are beyond our control could have a material adverse effect on our business, results of operations, financial condition, and cash flows. We maintain fuel storage and pumping facilities at our distribution centers and certain other service centers; however, we may experience shortages in the availability of fuel at certain locations and may be forced to incur additional expense to ensure adequate supply on a timely basis to prevent a disruption to our service schedules.

Fuel represents a significant operating expense for us, and we do not have any long-term fuel purchase contracts or any hedging arrangements to protect against fuel price increases. Fuel prices fluctuate greatly due to factors beyond our control, such as global supply and demand for crude oil and diesel, political events, price and supply decisions by oil producing countries and cartels, terrorist activities, and hurricanes and other natural or man-made disasters. Fuel prices have fluctuated significantly in recent years. Significant increases in fuel prices or fuel taxes resulting from these or other economic or regulatory changes which are not offset by base freight rate increases or fuel surcharges could have an adverse impact on our results of operations.

Our Asset-Based segment and certain operations of our ArcBest segment assess a fuel surcharge based on an index of national diesel fuel prices. Although fuel surcharge revenue generally offsets increases in direct diesel fuel costs when applied, we incur certain fuel costs that cannot be recovered with fuel surcharges, and other operating costs have been, and may continue to be, impacted by fluctuating fuel prices. The total impact of energy prices on other nonfuel-related expenses is difficult to ascertain. We cannot predict, with reasonable certainty, future fuel price fluctuations, the impact of energy prices on other cost elements, recoverability of fuel costs through fuel surcharges, and the effect of fuel surcharges on our overall rate structure or the total price that we will receive from our customers. While the fuel surcharge is one of several components in our overall rate structure, the actual rate paid by customers is governed by market forces and the overall value of services provided to the customer. When fuel surcharges constitute a higher proportion of the total freight rate paid, our customers are less receptive to increases in base freight rates. Prolonged periods of inadequate base rate improvements could adversely impact operating results as elements of costs, including contractual wage rates, continue to increase. Further, during periods of low freight volumes, shippers can use their negotiating leverage to impose lower pricing on compensatory fuel surcharges.

During periods of changing diesel fuel prices, the fuel surcharge and associated direct diesel fuel costs also vary by different degrees. Depending upon the rates of these changes and the impact on costs in other fuel- and energy-related areas, operating margins could be impacted. Fuel prices have fluctuated significantly in recent years. Whether fuel prices fluctuate or remain constant, operating results may be adversely affected if competitive pressures limit our ability to recover fuel surcharges. Throughout 2018, the fuel surcharge mechanism generally continued to have market acceptance among our customers; however, certain nonstandard pricing arrangements have limited the amount of fuel surcharge recovered. The negative impact on operating margins of capped fuel surcharge revenue during periods of increasing fuel costs is more evident when fuel prices remain above the maximum levels recovered through the fuel surcharge mechanism on certain accounts. Also, because our fuel surcharge recovery lags behind changes in fuel prices, our fuel surcharge recovery may not capture in any particular period the increased costs we pay for fuel, especially in periods in which fuel prices rapidly increase. In periods of declining fuel prices, fuel surcharge percentages also decrease, which negatively impacts the total billed revenue per hundredweight or revenue per shipment measure and, consequently, our revenues, and the revenue decline may be disproportionate to the corresponding decline in our fuel costs.

Higher fuel prices also cause customers of our FleetNet segment to seek cost savings throughout their businesses which may result in a reduction of miles driven and/or a deferral of maintenance practices that may reduce the volume of our maintenance service events, resulting in an adverse impact on the segment’s results of operations, financial condition and cash flows.

Increased prices for, or decreases in the availability of, new revenue equipment and decreases in the value of used revenue equipment, as well as higher costs of equipment-related operating expenses, could adversely affect our results of operations and cash flows.

In recent years, manufacturers have raised the prices of new revenue equipment significantly due to increased costs of materials and, in part, to offset their costs of compliance with new tractor engine and emissions system design requirements intended to reduce emissions, which have been mandated by the EPA, the NHTSA, and various state agencies such as those described in “Environmental and Other Government Regulations” within Part I, Item 1 (Business) of this Annual Report on Form 10-K. Greenhouse gas emissions regulations are likely to continue to impact the design and cost of equipment utilized in our operations as well as fuel costs. A number of states have mandated, and California and certain other states may continue to individually mandate, additional emission-control requirements for equipment which could increase equipment and fuel costs for entire fleets that operate in interstate commerce. If new equipment prices increase more than anticipated, we could incur higher depreciation and rental expenses than anticipated. Our third-party capacity providers, including owner operators for portions of our ArcBest segment operations, are also subject to increased regulations and higher equipment and fuel prices which will, in turn, increase our costs for utilizing their services or may cause certain providers to exit the industry which could lead to a capacity shortage and further increase our costs of securing third-party services. If we are unable to fully offset any such increases in expenses with freight rate increases and/or improved fuel economy, our results of operations could be adversely affected. 

Reduced fuel demand due to improved fuel economy may result in legislative efforts to increase fuel taxes which, if enacted, could increase our costs. If we are not able to offset fuel tax increases through reductions in other excise taxes or through increases in the rates we charge our customers, our business, results of operations, and financial condition could be adversely affected.

We depend on suppliers for equipment, parts, and services that are critical to our operations, which may be difficult to procure in the event of decreased supply. From time to time, some original equipment manufacturers (“OEMs”) of tractors and trailers may reduce their manufacturing output due to, for example, lower demand for their products in economic downturns or a shortage of component parts. Component suppliers may either reduce production or be unable to increase production to meet OEM demand, creating periodic difficulty for OEMs to react in a timely manner to increased demand for new equipment and/or increased demand for replacement components as economic conditions change. At times, market forces may create market situations in which demand outstrips supply. In those situations, we may face reduced supply levels and/or increased acquisition costs. An inability to continue to obtain an adequate supply of new tractors or trailers, as well as related parts and services, for our Asset-Based operations could have a material adverse effect on our business, results of operations, and financial condition.

During prolonged periods of decreased business levels, we and other trucking companies may make strategic fleet reductions, which could result in an increase in the supply of used equipment. When the supply exceeds the demand for used revenue equipment, the general market value of used revenue equipment decreases. Used equipment prices are also subject to substantial fluctuations based on availability of financing and commodity prices for scrap metal. If market prices for used revenue equipment decline, corresponding decreases in our established salvage values on equipment being used in our Asset-Based operations would increase our depreciation expense, and we could incur impairment losses on assets held for sale which could have an adverse effect on our results of operations.

Our total assets include goodwill and intangibles. If we determine that these items have become impaired in the future, our earnings could be adversely affected.

As of December 31, 2018, we had recorded goodwill of $108.3 million and intangible assets, net of accumulated amortization, of $68.9 million. Our goodwill and intangible assets resulted primarily from acquisitions in the ArcBest segment. Our annual impairment evaluations of goodwill and indefinite-lived intangible assets in 2018, 2017, and 2016 produced no indication of impairment of the recorded balances. However, significant declines in business levels or other changes in cash flow assumptions or other factors that negatively impact the fair value of the operations of our reporting units could result in impairment and a resulting non-cash write-off of a significant portion of our goodwill and intangible assets, which would have an adverse effect on our financial condition and results of operations.

Our nonunion defined benefit pension plan could have greater than anticipated funding requirements, which may adversely affect our financial condition and liquidity.

As further discussed in Note I to our consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K, our nonunion defined benefit pension plan was terminated with an effective date of December 31, 2017 and the plan received a favorable determination letter from the IRS regarding qualification of the plan termination in September 2018. In the fourth quarter of 2018, the plan began distributing immediate lump sum benefits elected by plan participants under plan termination. The plan will settle the remaining obligation for deferred benefits with the purchase of nonparticipating annuity contracts from insurance companies in first quarter 2019. The Company will make a cash contribution to the plan for the amount, if any, required to fund benefit distributions and annuity contract purchases in excess of plan assets.

We estimate nonunion pension expense, including noncash pension settlement charges, could total approximately $4.0 million in first quarter 2019, and cash funding could total approximately $7.0 million in first quarter 2019, although there can be no assurances in this regard. The final pension settlement charges and the actual amount we will be required to contribute to the plan to fund benefit distributions in excess of plan assets are dependent on various factors, including the value of plan assets, the amount of lump-sum benefit distributions paid to participants, and the cost to purchase annuity contracts to settle the pension obligation related to benefits for which participants elect to defer payment until a later date.

Our results of operations could be impacted by seasonal fluctuations, adverse weather conditions, and natural disasters.

Our operations are impacted by seasonal fluctuations which affect tonnage and shipment levels, and demand for our services and, consequently, revenues and operating results. Freight shipments and operating costs of our Asset-Based and ArcBest segments can be adversely affected by inclement weather conditions. The first quarter of each year generally has the lowest tonnage levels, although other factors, including the state of the U.S. and global economies, may influence quarterly freight tonnage levels. At the same time, first quarter operating expenses may increase due to, among other things, a decline in fuel economy because of higher fuel density in colder temperatures, higher accident frequency, increased claims, and potentially higher equipment repair expenditures caused by harsh weather. ArcBest segment operations are influenced by seasonal fluctuations that impact customers’ supply chains and the resulting demand for expedited services. Expedite shipments of our ArcBest segment may decline due to post-holiday slowdowns during winter months and plant shutdowns during summer months. Emergency roadside service events of the FleetNet segment are influenced by seasonal variations in service event volume, which is generally lower during mild weather conditions. Business levels of the household goods moving services provided by our ArcBest segment are generally lower in the non-summer months when demand for moving services is typically lower. In addition to the impact of weather on seasonal business trends, severe weather events and natural disasters, such as harsh winter weather, floods, hurricanes, earthquakes, tornadoes, or lightning strikes, could disrupt our operations or the operations of our customers or third-party service providers, destroy our assets, affect regional economies, or disrupt fuel supplies or increase fuel costs, each of which could adversely affect our business levels and operating results. Climate change may have an influence on the severity of weather conditions, which could adversely affect our freight shipments and business levels and, consequently, our operating results.

We are subject to certain risks arising from our international business.

We provide transportation and logistics services to and from international locations and are, therefore, subject to risks of international business, including, but not limited to, changes in the economic strength of certain foreign countries; social, political, and economic instability; the ability to secure space or services from third-party aircraft, ocean vessels, and other modes of transportation or suppliers; burdens of complying with a wide variety of domestic and international laws and regulations, including export and import laws as well as different liability standards and less-developed legal systems; unexpected changes in foreign laws, regulations, trade, monetary or fiscal policy; changes in or enactment of tariffs, quotas, customs and other restrictions and trade barriers; difficulties in enforcing contractual obligations and intellectual property rights; and changes in foreign exchange rates. Additional risks associated with our international business include restrictive trade policies and trade wars, new or increased trade tariffs imposed by the U.S. government, duties, taxes, or government royalties imposed by foreign governments, and changes in international tax laws and regulations. In addition, natural disasters, pandemics, war, acts of terrorism, and insurrections could impede our ability to provide satisfactory services to customers in international locations.

We are also subject to compliance with the Foreign Corrupt Practices Act (“FCPA”) and hold Customs-Trade Partnership Against Terrorism (“C-TPAT”) status for businesses within our Asset-Based and ArcBest segments. Failure to comply with the FCPA and local regulations in the conduct of our international business operations may result in criminal and civil penalties against us. If we are unable to maintain our C-TPAT status, we may face a loss of certain business due to customer requirements to deal only with C-TPAT participating carriers, because of the enhanced levels of supply chain security provided by participating in the C-TPAT program. In addition, loss of C-TPAT status may result in significant border delays, which could cause our international operations to be less efficient and more costly than competitors also operating internationally.

We operate in various Canadian provinces pursuant to operating authority granted by the Ministries of Transportation and Communications in such provinces, and we operate in Mexico by utilizing third-party carriers within the country. If the United States withdraws from or materially modifies the North American Free Trade Agreement, including by ratification of the United States-Mexico-Canada Agreement, or certain other international trade agreements or border policies, there could be more restrictive trade policies or increased regulatory complexities, which may result in increased costs and/or a reduction in the volume of freight shipped by our customers. Any such changes in trade policies and corresponding actions by other countries could have a material adverse effect on our business, results of operations, and financial condition.

Our business could be harmed by antiterrorism measures.

As a result of actual or threatened terrorist attacks on the United States, federal, state, and municipal authorities have implemented, continue to implement, and may implement in the future various security measures, including checkpoints and travel restrictions on large trucks. Although many companies would be adversely affected by any slowdown in the availability of freight transportation, the negative impact could affect our business disproportionately. For example, we offer specialized services that guarantee on-time delivery. If security measures disrupt the timing of deliveries, we could fail to meet the needs of our customers or could incur increased costs in order to do so. Additional security measures may also reduce productivity of our drivers and third-party transportation service providers, which would increase our operating costs. There can be no assurance regarding the implementation of new antiterrorism measures and such new measures may have a material adverse effect on our business, results of operations, or financial condition.

ITEM 6.SELECTED FINANCIAL DATA

The following table includes selected financial and operating data for the Company as of and for each of the five years in the period ended December 31, 2017.2018. This information should be read in conjunction with Item 7 (Management’s Discussion and Analysis of Financial Condition and Results of Operations) and Item 8 (Financial Statements and Supplementary Data) in Part II of this Annual Report on Form 10-K.

ITEM 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

ArcBest Corporation (together with its subsidiaries, the “Company,” “we,” “us,” and “our”) provides a comprehensive suite of freight transportation services and integrated logistics solutions. On November 3, 2016, we announced our plan to implement a new corporate structure that unified our sales, pricing, customer service, marketing, and capacity sourcing functions effective January 1, 2017, and allows us to operate as one logistics provider under the ArcBest® brand.

Our operations are conducted through three reportable operating segments:

The ArcBest and FleetNet reportable segments combined represent our Asset-Light operations. See additional segment descriptions in Part I, Item 1 (Business) and in Note M to our consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K. References to the Company, including “we,” “us,” and “our,” in this Annual Report on Form 10-K are primarily to the Company and its subsidiaries on a consolidated basis.

Contract Negotiations

As further discussed withinof December 2018, approximately 82% of the Asset-Based Operations section of Results of Operations, contract negotiations for the terms of ABF Freight’s union labor contract for the period subsequent to March 31, 2018, are in progress. The negotiation of terms of thesegment’s employees were covered under a collective bargaining agreement, isthe ABF National Master Freight Agreement (the “2018 ABF NMFA”), with the International Brotherhood of Teamsters (the “IBT”) which was ratified on May 10, 2018 by a very complex process.

Reclassifications

During the third quarter of 2017, we modified the presentation of segment expenses allocated from shared services. Shared services represent costs incurred to support all segments, including sales, pricing, customer service, marketing, capacity sourcing functions, human resources, financial services, information technology, legal, and other company-wide services. Certain overhead costs are not attributable to any segment and remain unallocated in “Other and eliminations.” Previously, expenses related to company-wide functions were allocated to segment expense line items by type of expense. Allocated expenses are now presented on a single shared services line within our operating segment disclosures. Reclassifications have been made to the prior period operating segment expenses to conform to the current year presentation. There was no impact on each segment’s total expenses as a result of the reclassifications.

Reclassifications

Effective January 1, 2018, we retrospectively adopted an amendment to Accounting Standards Codification Topic 715, Compensation – Retirement Benefits, (“ASC Topic 715”), which requires changes to the financial statement presentation of certain components of net periodic benefit cost related to pension and other postretirement benefits accounted for under ASC Topic 715. As a result of adopting this amendment, the service cost component of net periodic benefit cost continues to be included in operating expenses in our consolidated financial statements, but the other components of net periodic benefit cost, including pension settlement expense, are presented in other income (costs) for 2018, 2017, and 2016.

Reclassifications have been made to the prior period consolidated and segment operating expenses and operating income within MD&A to conform to the current year presentation of components of net periodic benefit cost in accordance with the amendment to ASC Topic 715. There was no change to consolidated net income or earnings per share as a result of the change in presentation under the new standard. The adoption of this accounting policy is further discussed in Note B and the detail of our net periodic benefit costs are presented in Note I to the consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K.
