SWIFT TRANSPORTATION COMPANY

ITEM 1.BUSINESS
Certain acronyms and terms used throughout this Annual Report on Form 10-K are specific to our company, commonly used in our industry, or are otherwise frequently used throughout our document. Definitions for these acronyms and terms are provided in the "Glossary of Terms," available in the front of this document.
Company Overview
Swift is a multi-faceted transportation services company, operating one of the largest fleets of truckload equipment in North America from over 40 terminals near key freight centers and traffic lanes. We principally operate in short- to medium-haul traffic lanes around our terminals and dedicated customer locations. During 2015,2016, our consolidated average operational truck count was 17,915,17,548, which along with our intermodal containers covered 2.2 billion miles for shippers throughout North America, contributing to consolidated operating revenue of $4.2$4.0 billion and consolidated operating income of $370.1$242.0 million. As of December 31, 2015,2016, our fleet was comprised of 15,21113,937 company tractors and 4,6534,429 owner-operator tractors, as well as 65,23364,066 trailers, and 9,1509,131 intermodal containers. Our customers have the opportunity to "one-stop-shop" for their truckload transportation needs with our extensive suite of service offerings, which includeincludes line-haul services, dedicated customer contracts, temperature-controlled units, intermodal freight solutions, cross-border United States/Mexico and United States/Canada freight, flatbed hauling, freight brokerage and logistics, and others.
Company Background
The Company began operations in 1966 with only one truck, with Jerry Moyes, along with his father and brother foundedas its founders. The founders originally conducted operations under the name of Common Market Distributing, later buying Swift Transportation Co., Inc. ("Swift Transportation") in 1966 with only one truck.. In the 1980s, Jerry Moyes bought out his partners, becoming the sole owner of Swift Transportation. In 1990, Swift Transportation went public on the NASDAQ stock market.
The 2007 Transactions In April 2007, Mr. Moyes and his wife contributed their ownership of all of the issued and outstanding shares of IEL to Swift Corporation in exchange for additional Swift Corporation shares. In May 2007, the Moyes Affiliates, contributed their shares of Swift Transportation common stock to Swift Corporation in exchange for additional Swift Corporation shares. Swift Corporation then completed its acquisition of Swift Transportation through a merger on May 10, 2007, thereby acquiring the remaining outstanding shares of Swift Transportation common stock. Upon completion of the 2007 Transactions, Swift Transportation became a wholly-owned subsidiary of Swift Corporation. At the close of market on May 10, 2007, the common stock of Swift Transportation ceased trading on NASDAQ.
The IPO On May 20, 2010, Swift Corporation formed Swift Transportation Company, a Delaware corporation. Swift Transportation Company did not engage in any business or other activities except in connection with its formation and the IPO and held no assets or subsidiaries prior to such offering. Immediately prior to the consummation of the IPO, Swift Corporation merged with and into Swift Transportation Company, with Swift Transportation Company surviving as a Delaware corporation. In the merger, all of the outstanding common stock of Swift Corporation was converted into shares of Swift Transportation Company Class B common stock on a one-for-one basis, and all outstanding stock options of Swift Corporation were converted into options to purchase shares of Class A common stock of Swift Transportation Company. All outstanding Class B shares are held by Mr. Moyes and the Moyes Affiliates. Swift Transportation Company went public on the NYSE in December 2010, at an initial trading price of $11.00 per share.
Central Acquisition On August 6, 2013, Swift acquired all of the outstanding capital stock of Central in a cash transaction. Jerry Moyes, our CEOthen-CEO and controlling stockholder, was the principal owner of Central. Given Mr. Moyes’Moyes' interests in the temperature-controlled truckload industry, our Board established a special committee comprised solely of disinterested, independent and disinterested directors in May of 2011 to evaluate Swift’sSwift's expansion of its temperature-controlled operations. The special committee evaluated alternative business opportunities, including organic growth and various acquisition targets, and negotiated the transaction contemplated by the stock purchase agreement, with the assistance of its independent financial advisors. Upon the unanimous recommendation of the special committee, the Central Acquisition was approved by the Board (with Mr. Moyes not participating in the vote).
Central is a premium service truckload carrier specializing in temperature-controlled freight transportation and was a large provider of temperature-controlled truckload services in the United States. With the addition of Central to its dedicated temperature-controlled business, Swift is one of the largest temperature-controlled truckload providers in the United States. Our accounting treatment of the Central Acquisition and other details are discussed in Note 1 in Part II, Item 8, Financial Statements and Supplementary Data.

Industry and Competition
Truckload carriers represent the largest part of the transportation supply chain for most retail and manufactured goods in North America and typically transport a full trailer (or container) of freight for a single customer from origin to destination without intermediate sorting and handling. Generally, the truckload industry is compensated based on miles, whereas the LTL industry is compensated based on package size and/or weight. Overall, the United States trucking industry is large, fragmented, and highly competitive. We compete with thousands of truckload carriers, most of whom operate much smaller fleets than we do. To a lesser extent, our intermodal services, as well as our freight brokerage and logistics business, compete with railroads, LTL carriers, logistics providers, and other transportation companies.
Our industry has encountered the following major economic cycles since 2000:
PeriodEconomic Cycle
2000 — 2001industry over-capacity and depressed freight volumes
  
2002 — 2006economic expansion
  
2007 — 2009freight slowdown, fuel price spike, economic recession, and credit crisis
  
2010 — present2013moderate recovery. The industry freight data began to show positive trends for both volume and pricing. The slow, steady growth is a result of moderate increases in gross domestic product, coupled with a tighter supply of available tractors. Trends in supply of available tractors were lower due to several years of below average truck builds, an increase in truckload fleet bankruptcies in 2009 and 2010, increasing equipment prices due to stringent EPA requirements, less available credit, and less driver availability.
2014 — presentreturn to pre-recession levels and relative stabilization. In 2014, total spending on transportation, which fell during the 2007 – 2009 recession, returned to pre-recession levels. Truck tonnage grew throughout 2014, followed by decelerating growth in 2015, and relative stabilization in 2016. Capacity became looser in 2015 and 2016, as inventory levels were high and large volumes of tractor purchases created a supply/demand imbalance, putting pressure on pricing. Fuel prices declined.
The principal means of competition in our industry are customer service, capacity, and price. In times of strong freight demand, customer service, and capacity become increasingly important, and in times of weak freight demand, pricing becomes increasingly important. Most truckload contracts (other than dedicated contracts) do not guarantee truck availability or load levels. Pricing is influenced by supply and demand.
The trucking industry faces the following primary challenges, which we believe we are well-positioned to address, as discussed under "Our Competitive Strengths" and "Company Strategy," below:
uncertainty in the extent and durationcumulative impacts of the current economic recovery;
potential reduction in driver pool from recent regulatory initiatives, such as hours-of-serviceELDs, hours-of service limitations for drivers, ELDs, and the FMCSA's CSA;
potential decreasesuncertainty in utilizationthe economic environment, including changing supply chain and consumer spending patterns;
pressures on volumes and pricing from new or changing regulatory constraints on drivers that may further decrease the utilization of an already shrinking excess industry capacity, excess customer inventories, and depressed shipping demand;
driver pool;shortages;
driver distraction and other unfavorable safety trends;
significant increases and rapid fluctuations in fuel prices; and
increased prices for new revenue equipment, design changes of new engines, and volatility in the used equipment sales market; andmarket.

Our Competitive Strengths
We aspire to achieve the themes of our mission and vision and believe our competitive strengths and strategies will enable us to attain our desired level of service to customers and results for our shareholders. We believe the following competitive strengths provide a solid platform for pursuing our goals and strategies:
North American Truckload Leader with Broad Terminal Network and a Modern Fleet
Our fleet size offers wide geographic coverage, while maintaining the efficiencies associated with significant traffic density within our operating regions. Our terminals are strategically located near key population centers, driver recruiting areas, and cross-border hubs, often in close proximity to our customers. This broad network offers benefits such as in-house maintenance, more frequent equipment inspections, localized driver recruiting, rapid customer response, and personalized marketing efforts. Our size allows us to achieve substantial economies of scale in purchasing items such as tractors, trailers, containers, fuel, and tires where pricing is volume-sensitive. We believe our scale also offers additional benefits in brand awareness and access to capital.
Our company tractorOTR sleeper fleet has an average age of 2.02.4 years for our approximately 11,20010,200 core operating sleeper units. By maintaining a newer fleet than mostmany of our industry competitors, we believe that we have the following advantages:
• Newer tractors typically have fewer repairs and lower operating costs.
• Newer tractors are available for dispatch more often.
• Drivers are typically more attracted to newer tractors, which helps with driver recruiting and retention.
• Many competitors that allowed their fleets to age excessively will likely face a deferred capital expenditure spike, accompanied by difficulty in replacing their tractors because while new tractor prices have increased and the value received for the old tractors will be low, and financing sources have diminished.has decreased.
 
High Quality Customer Service and Extensive Suite of Services
Our intense focus on customer satisfaction has helped us establish a strong platform for cross-selling our other services to our strong and diversified customer base. We believe customers continue to search for ways to better streamline their transportation management functions. We respond to this need by providing our customers with solutions that include a wide variety of shipping services, including general and specialized truckload, cross-border services, regional distribution, high-service dedicated operations, intermodal service, and surge capacity through fleet flexibility and brokerage and logistics operations. This breadth of service helps diversify our customer base and provides us with a competitive advantage, especially for customers with multiple needs and cross-border United States/Mexico and United States/Canada shipments.
 
Strong Owner-operator Business
We supplement our company tractor fleet with owner-operators, who own and operate their own tractors and are responsible for ownership and operating expenses. We believe that owner-operators provide significant advantages that primarily arise from the entrepreneurial motivation of business ownership. The owner-operators we contract with tend to be more experienced, have fewer accidents per million miles, and on average, produce higher weekly revenue per tractor than our company drivers.
 
Leader in Driver Development
Historically, driver recruiting and retention have been significant challenges for truckload carriers. To address these challenges, we employ nationwide recruiting efforts through our terminal network, operate eighteleven driver academies, partner with third-party driver training facilities, provide drivers with modern tractors, and promote numerous driver satisfaction initiatives.
 
Regional Operating Model
Our short- and medium-haul regional operating model contributes to higher revenue per mile and takes advantage of shipping trends toward regional distribution. We also experience less competition in our short- and medium-haul regional business from railroads. In addition, our regional terminal network allows our drivers to be home more often, which assists with driver retention.
 
Experienced Management, Aligned with Corporate Success
Our management team has a proven track record of growth and cost control. Management focuses on disciplined execution and financial performance by measuring our progress through a combination of financial metrics. We align management’smanagement's priorities with our stockholders’stockholders' through equity incentive awards and an annual performance-based bonus plan.

Company Strategy
Our key financial goals include improving our asset utilization, controlling costs, growing Adjusted EPS (defined in "Non-GAAP Financial Measures" under Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations)Operations), improving return on net assets, andas well as generating cash flow to reinvest in our business, repay debt, and return capital to our stockholders. We align our company focus to attain these goals by implementing the following strategies, which we believe also serve to minimize the impact of challenges currently faced in the trucking industry.
Profitable Revenue Growth
To increase freight volumes and yield, we intend to further penetrate our existing customer base, cross-sell our services, pursue new customer opportunities by leveraging our outstanding customer service and extensive suite of truckload services, and effectively price fuel surcharges.  In our pursuit to be best in class, we survey our customers and identify areas where we can accelerate the capture of new freight opportunities, improve our customers’customers' experience, and profit from enhancing the value our customers receive. We are continuously refining our freight management tools to allocate our equipment to more profitable loads and complementary shipping lanes. In addition to growth in our core over-the-roadOTR dry van truckload business, we are targeting expansion in the following areas:
Dedicated Services and Private Fleet OutsourcingDedicated contracts are often used by our customers with high-service and high-priority freight, sometimes to replace private fleets previously operated by them. The size and scale of our fleet and terminal network allows us to provide the equipment availability and high service levels required for dedicated contracts. We believe these opportunities will increase in times of scarce capacity in the truckload industry.
Temperature-controlledWithBeginning with the acquisition of Central Acquisition, we are now able to compete in the over-the-road temperature-controlled business to complement our dedicated temperature-controlled and our over-the-roadOTR dry van service offerings. Growth in the temperature-controlled market has kept pace withoutpaced the dry van market over the past ten years, and many of our current customers have a need for this service. We believe the scale provided by the Central Acquisition and our ability to penetrate our existing customer base will provideprovides us with future opportunities in this growing market.
Cross-border United States/Mexico and United States/Canada FreightThe combination of our United States, cross-border, customs brokerage, and Mexican operations enables us to provide efficient door-to-door service between the United States and Mexico, as well as Canada. We believe our sophisticated load security measures, as well as our DHS status as a C-TPAT carrier, allow us to offer more efficient service than most competitors and afford us substantial advantages with major cross-border United States/Mexico and United States/Canada shippers.
Freight Brokerage and LogisticsWe believe we have a substantial opportunity to continue to increase our non-asset-based freight brokerage and logistics services. We believe many customers increasingly seek transportation companies that offer both asset-based and non-asset-based services to ensure additional certainty that safe, secure, and timely truckload service will be available on demand. We intend to continue growing our transportation management and freight brokerage capability to build market share, earn marginal revenue on more loads, and preserve our assets for the most attractive lanes and loads.
IntermodalWe have favorable intermodal agreements with most major North American rail carriers, which have helped increase our volumes through more competitive pricing. Our intermodal presence, which expanded to service Mexico in 2013, complements our regional operating model and allows us to better serve customers in longer haul lanes and reduce our investment in fixed assets. Our intermodal fleet has more than doubled its size since its inception in 2005. In the latter half of 2014, we added over 400 containers. With these additions, ourOur capacity totalstotaled 9,131 and 9,150 containers as of December 31, 2015.2016 and 2015, respectively.

Increase Asset Productivity and Return on Capital
Because of our size and operating leverage, even small improvements in our asset productivity and yield can have a significant impact on our operating results. We believe we have substantial opportunity to improve the productivity and yield of our existing assets as follows:
Disciplined Tractor Fleet GrowthWe will continue to focus on maintaining discipline regarding the timing and extent of company tractor fleet growth, based on availability of high-quality freight.
Process Improvement and System IntegrationSuccessful implementation of process improvements and effective systems integration will achieve more efficient utilization of our tractors, trailers, and drivers' available hours of service.hours-of-service. For example, our entire tractor fleet is retrofitted with ELDs, which we believe can help us more efficiently utilize our drivers' available hours-of-service.

Continue to Focus on Efficiency and Cost Control
To ensure that we respond appropriately to economic change, we closely manage our costs and capital resources and continually monitor the economic environment, as well as its potential impact on our customers and end-markets. We presently have ongoing efforts in the following areas that we expect will yield benefits in future periods:
Tractor Capacity 
In order to balance freight flows and reduce deadhead miles, we manage the flow of our tractor capacity through our network.
Driver SatisfactionImproving driver satisfaction typically reduces turnover costs and improves performance. We believe our driver development programs, including our driver academies and nationwide recruiting, will become increasingly advantageous to us in countering attrition effects stemming from noncompliance with internal policies and procedures, as well as recent regulatory initiatives (discussed below). In addition, we believe that the negative impact of such regulations will be partially mitigated by our average length of haul, regional terminal network, and less mileage-intensive operations, such as intermodal, dedicated, brokerage, and cross-border operations.
Waste ReductionReducing waste in shop methods and procedures and in other administrative processes remains important to us.
Pursue Selected Acquisitions
From time to time, we take advantage of opportunities to add complementary operations to our company by pursuing acquisitions. Acquisitions can provide us an opportunity to expand our fleet with customer revenue and drivers already in place. In our history, we have completed 13 acquisitions, including Central in 2013, most of which were immediately integrated into our existing business. Given our size in relation to most competitors, we expect most future acquisitions to be integrated quickly.
We believe that by achieving profitable revenue growth, improving asset utilization, continuing to control costs, and streamlining our processes, we will be able to grow our Adjusted EPS and our return on net assets, while generating free cash flow to reinvest in our business, potentially acquire complementary businesses, repay debt, reduce our leverage ratio, and return capital to our stockholders. These goals are in part dependent on continued improvement in industry-wide truckload volumes and pricing. Although we expect the economic environment and capacity constraints in our industry to support achievement of our goals, we have limited ability to affect industry volumes and pricing and cannot provide assurance that this environment will sustain. Nevertheless, we believe our competitive strengths and the currentexpected supply and demand environment in the truckload industry are aligned to support the achievement of our goals through the strategies outlined above.

Customers and Marketing
Customers Our customers are typically large corporations in the retail (including discount and online retail), food and beverage, consumer products, paper products, transportation and logistics, housing and building, automotive, and manufacturing industries. Many of our customers have extensive operations, geographically distributed locations, and diverse shipping needs. Customer satisfaction is an important priority for us, which is demonstrated by the numerous "carrier of the year" or similar awards received from our customers over the past several years. Such achievements have helped us maintain a large and stable customer base featuring Fortune 500 and other leading companies from a number of different industries. Consistent with industry practice, our typical customer contracts (other than dedicated contracts) do not guarantee shipment volumes by our customers or truck availability by us. This affords us and our customers some flexibility to negotiate rates in response to changes in freight demand and industry-wide truck capacity. We believe our fleet capacity, terminal network, customer service and breadth of services offer a competitive advantage to major shippers, particularly in times of rising freight volumes when shippers must quickly access capacity across multiple facilities and regions.

We typically purchase or lease tractors and trailers manufactured to our specifications. We follow a comprehensive maintenance program designed to reduce downtime and enhance the resale value of our equipment. We have major maintenance facilities in the following locations:
Phoenix, Arizona
Memphis, Tennessee
Greer, South Carolina
West Valley City, Utah
Columbus, Ohio
Laredo, Texas
Jurupa Valley, California
In addition to these maintenance facilities, we perform routine servicing and maintenance of our revenue equipment at most of our regional terminal facilities, in an effort to avoid costly on-road repairs and deadhead miles. The contracts governing our equipment purchases typically contain specifications of equipment, projected delivery dates, warranty terms, and trade or return conditions, and are cancelable upon 60 to 90 days' notice without penalty.
In 2015, we accelerated ourOur tractor trade-in cycle from an average of 48 to 72 months to an average of 36 to 48 months,range, depending on equipment type and usage. We believe that ourusage, was 42 to 48 months and 36 to 48 months, during 2016 and 2015, respectively. Our newer equipment has enhanced features, which tendwe believe tends to lower the overall life cycle costs by reducing safety-related expenses, lowering repair and maintenance expenses, improving fuel economy, and improving driver satisfaction. In 20162017 and beyond, we will continue to monitor the appropriateness of this shorterrelatively short tractor trade-in cycle against the lower capital expenditure and financing costs of a longer tractor trade-in cycle, based on current and future business needs.

Technology
Trucks We equip virtually all of our trucks with certain OmniTRACStm technologies that enhance communication between the regional terminals and corporate headquarters, as well as the added benefits of ELDs, text-to-voice messaging, and turn-by-turn directions designed specifically for our industry. This allows us to alter driver routes rapidly, in case of urgent customer requests, adverse weather conditions, road closures, or other potential delays. It also enables our drivers to timely communicate route status or the need for emergency repairs. These technologies have afforded us additional productivity, improved safety, and increased customer and driver satisfaction.
We reduce costs through programs that manage equipment maintenance, select fuel purchasing locations in our nationwide network of terminals and approved truck stops, and inform us of inefficient or undesirable driving behaviors that are monitored and reported through electronic engine sensors and cameras. We believe our technologies and systems are superior to those employed by most of our smaller competitors.
OurTrailers and Containers The majority of our trailers and containers are equipped with tracking devices that monitor locations of empty and loaded equipment via satellite. NotificationWe also use geofencing, along with other on-site and off-site tracking capabilities to ensure we are alerted when our equipment is sentnot located where we are expecting it to us if a unit is moved outside of the electronic geofence encasing on each piece of equipment. This enablesbe located. These technological capabilities enable us to identify unused or hijackedstolen units, enhance our ability to charge for units detained by customers, and reduce theft.
Enterprise Resource Planning ("ERP") In 2016, we began preliminary planning phases to replace our current ERP with a new solution, including identification of needs, request for proposal, evaluation of alternatives, and final selection of a new ERP. Beginning in 2017, the Company will be in the implementation phases of replacing its current ERP system with a new cloud-based solution. The core applications of the new ERP within finance, human resources, and payroll are expected to go live in 2018.
Employees
The strength of our company is our people, working together with common goals. There were approximately 20,80021,800 full-time employees in our total headcount of approximately 21,00021,900 employees as of December 31, 2015,2016, which was comprised of:
Company drivers (including driver trainees)15,85016,600
Technicians and other equipment maintenance personnel1,2001,300
Support personnel (such as corporate managers, sales, and administrative personnel)3,9504,000
Total21,00021,900
As of December 31, 2015,2016, our 819821 Trans-Mex drivers in Mexico were our only employees represented by a union.
Company Drivers All of our drivers must meet specific guidelines relating primarily to safety records, driving experience, and personal evaluations, including a physical examination and mandatory drug and alcohol testing. Upon hire, drivers are trained in our policies, operations, safety techniques, and the fuel-efficient operation of the equipment. All new drivers must pass a safety test and have a current CDL. In addition, we have ongoing driver efficiency and safety programs to ensure that our drivers comply with our safety procedures.
We have established eighteleven driver academies across the United States. Our academies are strategically located in areas where external driver-training organizations were lacking. In other areas of the United States, we have contracted with driver-training schools, which are managed by third parties. There are certain minimum qualifications for candidates to be accepted into the

11

SWIFT TRANSPORTATION COMPANY

academy, including passing the DOT physical examination and drug/alcohol screening. Students are required to complete three weeks of instructor-led study/training and then spend a minimum of 200 behind-the-wheel hours, driving with an experienced trainer.
In order to attract and retain qualified drivers and promote safe operations, we purchase high quality tractors equipped with optional comfort and safety features. We base our drivers at terminals and monitor each driver’sdriver's location in order to schedule routing for our drivers so they can return home regularly. The majority of company drivers are compensated based on industry standard dispatched miles, loading/unloading, and number of stops or deliveries, plus bonuses. The driver’sdriver's base pay per mile increases with the driver’sdriver's length of experience. Our driver ranking system measures safety, compliance, customer service, and number of miles driven. Higher rankings provide drivers with additional benefits and/or privileges, such as special recognition, the ability to self-select freight, and the opportunity for increased pay.
Upon enrollment eligibility, drivers employed by us may participate in company-sponsored health, life and dental insurance plans and participate in our 401(k) and employee stock purchase plans.
Terminal Staff Our largerMost of our large terminals are staffed with terminal leaders, fleet leaders, driver leaders, planners, safety coordinators, shop leaders, technicians, and customer service representatives. Our terminal leaders work with driver leaders, customer service representatives, and other operations personnel to coordinate the needs of both our customers and our drivers. Terminal leaders are also responsible for soliciting new customers and serving existing customers in their areas. Each fleet leader supervises approximately five

12




SWIFT TRANSPORTATION COMPANY

driver leaders at our larger terminals. Each driver leader is responsible for the general operation of approximately 40 to 50 trucks and their drivers, focusing on driver retention, productivity per truck, routing, fuel consumption, andfuel efficiency (with respect to driver-controllable idle time), safety, and scheduled maintenance. Customer service representatives are assigned specific customers to ensure specialized, high-quality service, and frequent customer contact.
Owner-Operators
In addition to Swift-employed company drivers, we enter into contractor agreements with third parties who own and operate tractors (or hire their own drivers to operate the tractors) that service our customers. We pay these owner-operators for their services, based on a contracted rate per mile. By operating safely and productively, owner-operators can improve their own profitability and ours. Owner-operators are responsible for most costs incurred for owning and operating their tractors. For convenience, we offer owner-operators maintenance services at our in-house shops and fuel at our terminals at competitive and attractive prices. As of December 31, 2015,2016, owner-operators comprised approximately 23%24.1% of our total fleet, as measured by tractor count.
We offer tractor financing to independent owner-operators through our financing subsidiaries. Our financing subsidiaries generally lease premium equipment from the original equipment manufacturers and sublease the equipment to owner-operators. The owner-operators are qualified for financing, based on their driving and safety records. In the event of default, our financing subsidiaries have the option to repossess the tractor and sublease it to a replacement owner-operator.
Safety and Insurance
We take pride in our safety-oriented culture and maintain an active safety and loss-prevention program, which is led by regional safety management personnel at each of our terminals. We also equip our tractors with many safety features, such as roll-over stability devices and critical-event recorders, to help prevent or reduce the severity of accidents. We self-insure for a significant portion of our claims exposure and related expenses. We currently carry sixseven main types of insurance, which generally have the following self-insured retention amounts, maximum benefits per claim, and other limitations:
InsuranceLimits
Automobile Liability, General Liability, and Excess Liability$350.0250.0 million of coverage per occurrence ($250.0350.0 million aggregated limits through October 31, 2015,2016), subject to a $10.0 million per-occurrence, self-insured retention)retention per-occurrence.

Property and Catastrophic Physical Damage$150.0 million limit for property and $100.0 million limit for vehicle damage, excluding over the road exposures, subject to a $1.0 million deductible
Workers' Compensation/Employers' LiabilityStatutory coverage limits; employers' liability of $1.0 million bodily injury by accident and disease, subject to a $5.0 million self-insured retention for each accident or disease
Employment Practices LiabilityPrimary policy with a $10.0 million limit subject to a $2.5 million self-insured retention plus an excess liability policy that provides coverage for the next $17.5 million of liability for a total coverage limit of $27.5 million
Health CareAs of January 1, 2015, we are fully insured on our medical benefits, subject to contributed premiums. Prior to January 1, 2015, we had a $500 thousand specific deductible with an aggregating individual deductible of $150 thousand beginning January 1, 2013, of each employee health care claim, as well as commercial insurance for the balance.
Director and Officer InsuranceWe maintain insurance that covers our directors and officers for losses and expenses arising out of claims, based on acts or omissions in their capacities as directors or officers.

We insure certain casualty risks through our wholly-owned captive insurance subsidiaries, Mohave and Red Rock. Mohave and Red Rock provide reinsurance associated with a share of our automobile liability risk. In addition to insuring a proportionate share of our corporate casualty risk, Mohave provides reinsurance coverage to third-party insurance companies associated with our affiliated companies’companies' owner-operators.
While under dispatch and our operating authority, the owner-operators we contract with are covered by our liability coverage and self-insurance retention limits. However, each is responsible for physical damage to his or her own equipment, occupational accident coverage, and liability exposure while the truck is used for non-company purposes. Additionally, fleet operators are responsible for any applicable workers’workers' compensation requirements for their employees.
We regulateFor safety, we electronically govern the speed of substantially all of our company tractors to a maximum of 62 miles per hour and for safety reasons have contractually agreedhour. Additionally, our owner-operator contracts include statements that owner-operators must comply with owner-operators tothe Company's speed policy, which indicates that they must limit their speed to 6867 miles per hour. These adopted speed limits are below the limits established by statute in many states. We believe our adopted speed limits for company drivers reduce the frequency and severity of accidents, enhance fuel efficiency, and reduce maintenance expense, when compared to operating without our imposed speed limits. Substantially all

Fuel
We actively manage our fuel purchasing network in an effort to maintain adequate fuel supplies and reduce our fuel costs. Additionally, we utilize a fuel surcharge program to pass a majority of increases in fuel costs to our customers. In 2015,2016, we purchased 17%16.9% of our fuel in bulk at 5756 Swift and dedicated customer locations across the United States and Mexico. We purchased substantially all of the remainder through a network of retail truck stops with which we have negotiated volume purchasing discounts. The volumes we purchase at terminals and through the fuel network vary based on procurement costs and other factors. We seek to reduce our fuel costs by routing our drivers to truck stops when fuel prices at such stops are cheaper than the bulk rate paid for fuel at our terminals. We store fuel in underground storage tanks at two of our bulk fueling terminals and in above-ground storage tanks at our other bulk fueling terminals. We believe that we are sufficiently in compliance with applicable environmental laws and regulations relating to the storage and dispensing of fuel.
Seasonality
In the truckload industry, results of operations generally show a seasonal pattern. As customers ramp up for the year-end holiday season, the late third and fourth quarters have historically been our strongest volume quarters. As customers reduce shipments after the winter holiday season, the first quarter has historically been a lower volume quarter for us than the other three quarters. In recent years, the macro consumer buying patterns combined with shippers’shippers' supply chain management, which historically contributed to the fourth quarter "peak" season, continued to evolve. As a result, our fourth quarter 2016, 2015, and 2014 and 2013 volumes did not peak early in the quarter. Instead, volumes during the fourth quarter were more evenly disbursed throughout the quarter, rather than peaking early inwith a brief decrease the quarter.week of the U.S. Thanksgiving holiday and then tapering off the last week of the year. In the eastern and mid-western United States, and to a lesser extent in the western United States, during the winter season our equipment utilization typically declines and operating expenses generally increase, with fuel efficiency declining because of engine idling and severe weather sometimes creating higher accident frequency, increased claims, and more equipment repairs. Revenue may also be affected by holidays as a result of curtailed operations or vacation shutdowns, because our revenue is directly related to available working days of shippers. From time to time, we also suffer short-term impacts from severe weather and similar events, such as tornadoes, hurricanes, blizzards, ice storms, floods, fires, earthquakes, and explosions that could harm our results of operations or make our results of operations more volatile.
Environmental Regulation
General — We have bulk fuel storage and fuel islands at many of our terminals, as well as vehicle maintenance, repair, and washing operations at some of our facilities, which exposes us to certain environmental risks. Soil and groundwater contamination have occurred at some of our facilities in prior years, for which we have been responsible for remediating the environmental contamination. Also, less than one percent of our total shipments contain hazardous materials, which are generally rated as low- to medium-risk. In the past, we have been responsible for the costs of clean-up of cargo and diesel fuel spills caused by traffic accidents or other events.
We have instituted programs to monitor and mitigate environmental risks and maintain compliance with applicable environmental laws dealing with the hauling, handling, and disposal of hazardous materials, fuel spillage or seepage, emissions from our vehicles and facilities, engine-idling, discharge and retention of storm water, and other environmental matters. As part of our safety and risk management program, we periodically perform internal environmental reviews. We are a Charter Partner in the EPA’sEPA's SmartWay Transport Partnership, a voluntary program promoting energy efficiency and air quality. We believe that our operations are sufficiently in compliance with current laws and regulations and do not know of any existing environmental condition that would reasonably be expected to have a material adverse effect on our business or operating results.

If we are held responsible for the cleanup of any environmental incidents caused by our operations or business, or if we are found to be in violation of applicable laws or regulations, we could be subject to liabilities, including substantial fines or penalties or civil and criminal liability. We have paid penalties for spills and violations in the past.past; however, they have not been material to our financial results or position.
Greenhouse Gas Emissions and Fuel Efficiency Standards — In 2008 the State of California's Air Resources Board ("ARB") approved the Heavy-Duty Vehicle GHG Emission Reduction Regulation in efforts to reduce GHG emissions from certain long-haul tractor-trailers that operate in California by requiring them to utilize technologies that improve fuel efficiency (regardless of where the vehicle is registered). The regulation required owners of long-haul tractors and 53-foot trailers to replace or retrofit their vehicles with aerodynamic technologies and low rolling resistance tires. The regulation also contained certain emissions and registration standards for refrigerated trailer operators.trailers.
Thereafter, the United States EPA and the National Highway Traffic Safety Administration ("NHTSA") began taking coordinated steps in support of a new generation of clean vehicles and engines through reduced GHG emissions and improved fuel efficiency at a national level.

Table of ContentsGlossary of Terms



SWIFT TRANSPORTATION COMPANY

Phase 1: In September 2011, the United States EPA finalized federal regulations for controlling GHG emissions, beginning with model-year 2014 medium- and heavy-duty engines and vehicles and increasing in stringency through model-year 2018. The federal regulations relate to efficient engines, use of auxiliary power units, mass reduction, low rolling resistance tires, improved aerodynamics, improved transmissions, and reduced accessory loads.
In December 2013, California's ARB approved regulations to align its GHG emission standards and test procedures, as well as its tractor-trailer GHG regulation, with the federal Phase 1 GHG regulation.
Phase 2: In June 2015, the EPA and NHTSA, working in concert with California's ARB, formally announced a proposed national program establishing Phase 2 of the GHG emissions and fuel efficiency standards for medium- and heavy-duty vehicles for model-year 2018 and beyond. In August 2016, the EPA and NHTSA announced the final rule regarding Phase 2, which builds upon Phase 1, and would apply to certain trailer types beginning with model-year 2018 for EPA standards (voluntary for NHTSA standards through model-year 2020). Tractors and certain trailer types would be subject to the Phase 2 standards beginning with model-year 2021, increasing in stringency through model-year 2024, and phasing in completely by model-year 2027. This rule marks the first time federal mandates will be applied to trailers, with respect to aerodynamics and low-rolling resistance tires. The final rule was effective December 27, 2016.
Current and proposed GHG regulations could impact us by increasing the cost of new tractors and trailers, impairing productivity, and increasing our operating expenses.
Climate-change Proposals — Federal and state lawmakers are considering a variety of climate-change proposals related to carbon emissions and GHG emissions. The proposals could potentially limit carbon emissions for certain states and municipalities, which continue to restrict the location and amount of time that diesel-powered tractors (like ours) may idle.
Industry Regulation
Our operations are regulated and licensed by various federal, state, and local government agencies in North America, including the DOT, the FMCSA, and the DHS, among others. Our company, as well as our drivers and contracted owner-operators, must comply with enacted governmental regulations regarding safety, equipment, environmental protection, and operating methods. Examples include regulation of equipment weight, equipment dimensions, fuel emissions, driver hours-of-service, driver eligibility requirements, on-board reporting of operations, and ergonomics. The following discussion presents recently enacted federal, state, and local regulations that have an impact on our operations.
Hours-of-service — In December 2011, the FMCSA released its final rule on hours-of-service, which was effective on July 1, 2013. The key provisions included:
retaining the current 11-hour daily driving time limit;
reducing the maximum number of hours a truck driver can work within a week from 82 hours to 70 hours; and
limiting the number of consecutive driving hours a truck driver can work to eight hours before requiring the driver to take a 30 minute break.
Since 2004 the hours-of-service rules allowed drivers to restart their duty-cycle clocks every 34 hours to begin a new work week. From July 2013 through December 2014, the FMCSA required that drivers include 1:00 a.m. to 5:00 a.m. on consecutive days for applying the restart, which was also capped at once per week, or 168 hours. On December 13, 2014, Congress passed the fiscal year 2015 Omnibus Appropriations bill, which temporarily suspended enforcement of the 1:00 to 5:00 am provision and the 168-hour rule until September 30, 2015. The restart provision was again suspended onin December 18, 2015, pending completion of a study regarding driver restarts, when Congress passed the fiscal year 2016 Omnibus Appropriations bill.  All other provisions of the hours-of-service rules that went into effect on July 1, 2013 remained unchanged. A study
In December 2016, a short-term funding bill was passed by Congress, which clarified the hours-of-service rule. The provision in the bill requires the DOT to proceed with the existing 34-hour restart provision in the hours-of-service rule to ensure continuity in federal rest regulations, should the report on the effectivenessstudy (noted above) not meet the criteria set by Congress. If the report, which was completed in December 2015, successfully addresses fatigue, then the rules would go back into effect. We are not aware of any further developments related to the suspended restart provisions was recently completed. The FMCSA could move to reinstate these provisions or request that Congress remove the suspension.hours-of-service rules.

BASICs — In December 2010, the FMCSA introduced a new enforcement and compliance model that ranks both fleets and individual drivers on seven categories of safety-related data, eventually replacing the current SafeStat model. The seven categories of safety-related data, known as BASICs, currently include Unsafe Driving, Fatigued Driving (hours-of-service), Driver Fitness, Controlled Substances/Alcohol, Vehicle Maintenance, Hazardous Materials Compliance, and Crash Indicator.
Certain BASICs information was initially published and made available to carriers, as well as the general public. However, in December 2015, as part of the Fixing America's Surface Transportation ("FAST") Act, Congress mandated that the FMCSA remove all CSA scores from public view until a more comprehensive study regarding the effectiveness of BASICs improving

Implementation and effective dates are unclear, as thereunclear. In October 2016, the FMCSA outlined proposed changes to its safety measurement system and sought public feedback through December 2016 before deciding whether to adopt the proposed changes. SafeStat is currently no proposed rulemaking with respect to BASICs, leaving SafeStat the authoritative safety measurement system in effect. We currently have a satisfactory SafeStat DOT rating, which is the best available rating under the current safety rating scale.
Safety Fitness Determination In January 2016, the FMCSA published a Notice of Proposed Rulemaking ("NPRM") in the Federal Register, regarding carrier safety fitness determination. The NPRM proposes new methodologies that would determine when a motor carrier is not fit to operate a CMV.commercial motor vehicle. Key proposed changes included in the NPRM are as follows:
There would be only one safety rating of "unfit," as compared to the current rules, which have three safety ratings (satisfactory, conditional, and unsatisfactory).
Carriers could be determined "unfit" by failing two or more BASICs, investigation results, or a combination of the two.
Stricter standards would be used for BASICs with a higher correlation to crash risk (Unsafe Driving and Hours-of-Service Compliance).
All investigation results would be used, not just results from comprehensive on-site reviews.
Violations of a revised list of "critical" and "acute" safety regulations would result in failing a BASIC.
Carriers would be assessed monthly.
The FMCSA estimates thatPublic comments on the proposed rule would increase the number of carriers determined to be "unfit" by more than two and a half times.were due in June 2016.
Moving Ahead for Progress in the 21st Century Bill — OnIn July 6, 2012, Congress passed the Moving Ahead for Progress in the 21st Century bill into law. Included in the highway bill was a provision that mandates ELDselectronic logging devices in commercial motor vehicles to record hours-of-service. Additionally, in response to the bill, a final rule related to entry-level driver training was passed in 2016, as well as amendments to the Drug and Alcohol Clearinghouse rules.
Electronic Logging Devices ("ELD") During 2012, the FMCSA published a Supplemental NPRM, announcing its plan to proceed with the ELDs and hours-of-service supporting documents rulemaking. In December 2015, theThe ELD rule became final in December 2015, as published in the Federal Register. Register, with an effective date of February 16, 2016. The ELD rule phases in over a four-year period:
Phase 1 (February 16, 2016 through December 18, 2017): Carriers and drivers subject to the rule may voluntarily use ELDs or use other forms of logging devices.
Phase 2 (December 18, 2017 through December 16, 2019): Carriers and drivers subject to the rule can use Automatic On-board Recording Devices ("AOBRD") that were installed prior to December 18, 2017 or ELDs certified and registered after December 16, 2015.
Phase 3 (after December 16, 2019): All drivers and carriers subject to the rule must use certified and registered ELDs that comply with the requirements of the ELD regulations.
Although the final ELD rule may have a large impact on the industry as a whole, we do not expect a significant impact on Swift, as we previously installed ELDs in our operational trucks in conjunction with our efforts to improve efficiency and communications with drivers and owner-operators.
Entry-Level Driver Training ("ELDT") — In December 2016, the FMCSA established new minimum training standards for certain individuals applying for (or upgrading) a Class A or Class B commercial driver's license, or obtaining a hazardous materials, passenger, or school bus endorsement on their commercial driver's license for the first time. These individuals are subject to the ELDT requirements and must complete a prescribed program of theory and behind-the wheel instruction. The final rule requires that behind-the-wheel proficiency of an entry-level truck driver be determined solely by the instructor's evaluation of how well the driver-trainee performs the fundamental vehicle controls skills and driving procedures set forth in the curricula, but does not have a minimum training hours requirement, as proposed by the FMCSA earlier in 2016. The final rule went into effect on February 6, 2017, with a compliance date of February 7, 2020. Upon the compliance date, training schools will be required to register with the FMCSA's Training Provider Registry and certify that their program meets the classroom and driving standards.
Commercial Driver's License Drug and Alcohol Clearinghouse— In December 2016, the FMCSA amended the Federal Motor Carrier Safety Regulations to establish requirements of the Commercial Driver's License Drug and Alcohol Clearinghouse, a database under its administration that will contain information about violations of the FMCSA's drug and alcohol testing program for holders of commercial driver's licenses. In addition to requiring employers to check the database for driver applicant drug and alcohol test failures, the final ELD rule may have a large impact onrequires employers to check the industry as a whole, we do not expect a significant impact on Swift, as we previously installed ELDs in our operational trucks in conjunction with our effortsdatabase to improve efficiency and communications with drivers and owner-operators.determine

whether current employees have incurred a drug or alcohol violation that would prohibit them from performing safety-sensitive functions. The final rule is effective January 4, 2017, with a compliance date of January 6, 2020.
Prohibiting Coercion of Commercial Motor Vehicle Drivers — InIn November 2015, the Prohibiting Coercion of Commercial Motor Vehicle Drivers rule became final, as published in the Federal Register and adopted by the FMCSA. The rule explicitly prohibits motor carriers from coercing drivers to violate certain FMCSA regulations, including driver hours-of-service limits, CDL regulations, drug and alcohol testing rules, and hazardous materials regulations, among others. Under the new rule, drivers can report incidents of coercion to the FMCSA, who is authorized to issue penalties against the motor carrier.
Speed Limiting Devices — In September 2016, the NHTSA and FMCSA proposed regulations that would require speed limiting devices on vehicles with a gross vehicle weight rating of more than 26,000 pounds for the service life of the vehicle. The speed is expected to be limited to 62, 65, or 68, but would ultimately be set by the final rule. Based on the agencies' review of the available data, limiting the speed of these heavy vehicles would reduce the severity of crashes involving these vehicles and reduce the resulting injuries and fatalities. Public comments on the proposed rule were due in November 2016.
For safety, we electronically govern the speed of substantially all of our company tractors to a maximum of 62 miles per hour. Additionally, our owner-operator contracts include statements that owner-operators must comply with the Company's speed policy, which indicates that they must limit their speed to 67 miles per hour.
Other Regulation
The TSA — In the aftermath of the September 11, 2001 terrorist attacks, federal, state, and municipal authorities implemented and continue to implement various security measures on large trucks, including checkpoints and travel restrictions. The TSA adopted regulations that require drivers applying for or renewing a license for carrying hazardous materials to obtain a TSA determination that they are not a security threat.
WOTC — In December 2014, United States President, Barack Obama, signed the Tax Increase Prevention Act of 2014 ("TIPA"). Among other things, TIPA extended 50% bonus depreciation and the Work Opportunity Tax Credit ("WOTC"). In December 2015, President Obama signed the Protecting Americans from Tax Hikes ("PATH") Act of 2015. Among other things, PATH further extended 50% bonus depreciation and WOTC. The financial impact of these regulations is discussed in Note 2011 in Part II, Item 8.

General information about Swift is provided, free of charge, on our website, www.swifttrans.com. This website also includes our annual reports on Form 10-K with accompanying XBRL documents, quarterly reports on Form 10-Q with accompanying XBRL documents, current reports on Form 8-K, and amendments to those reports that are filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as soon as reasonably practicable once the material is electronically filed or furnished to the SEC.
ITEM 1A.RISK FACTORS
When evaluating our company, the following risks should be considered in conjunction with the other information contained in this annual report on Form 10-K. If we are unable to mitigate and/or are exposed to any of the following risks in the future, then there could be a material, adverse effect on our business, results of operations, or financial condition.
Strategic Risk
The truckload industry is affected by economic and business risks that are largely beyond our control.
The truckload industry is highly cyclical, and our business is dependent on a number of factors that may have a negative impact on our results of operations, many of which are beyond our control. We believe that some of the most significant of these factors are economic changes that affect supply and demand in transportation markets, such as:
recessionary economic cycles, such as the period from 2007 to 2009;
changes in customers’customers' inventory levels, including shrinking product/package sizes, and in the availability of funding for their working capital;
excess tractor capacity in comparison with shipping demand; and
downturns in customers’customers' business cycles.

The risks associated with these factors are heightened when the United States economy is weakened. Some of the principal risks during such times, which we experienced during the most recent recession, are as follows:
low overall freight levels, which maytypically impair our asset utilization;
customers with credit issues and cash flow problems;
changing freight patterns from redesigned supply chains, resulting in an imbalance between our capacity and customer demand;
customers bidding out freight or selecting competitors that offer lower rates, in an attempt to lower their costs, forcing us to lower our rates or lose freight; and
more deadhead miles incurred to obtain loads.
We are also are subject to cost increases outside our control (for example fuel and diesel prices) that could materially reduce our profitability if we are unable to increase our rates sufficiently.
In addition, events outside our control, such as strikes or other work stoppages at our facilities or at customer, port, border, or other shipping locations, actual or threatened armed conflicts or terrorist attacks, efforts to combat terrorism, military action against a foreign state or group located in a foreign state, or heightened security requirements could lead to reduced economic demand, reduced availability of credit, or temporary closing of shipping locations or United States borders.
The truckload industry is highly competitive and fragmented, which subjects us to competitive pressures pertaining to pricing, capacity, and service.
Our operating segments compete with many truckload carriers, and some LTL carriers, railroads, logistics, brokerage, freight forwarding, and other transportation companies. Additionally, some of our customers may utilize their own private fleets rather than outsourcing loads to us. Some of our competitors may have greater access to equipment, a wider range of services, greater capital resources, less indebtedness, or other competitive advantages. Numerous competitive factors could impair our ability to maintain or improve our profitability. These factors include the following:
Many of our competitors periodically reduce their freight rates to gain business, especially during times of reduced growth in the economy. This may make it difficult for us to maintain or increase freight rates, or may require us to reduce our freight rates, or lose freight. Additionally, it may limit our ability to maintain or expand our business.
Since some of our customers also operate their own private trucking fleets, they may decide to transport more of their own freight.
Some shippers have selected core carriers for their shipping needs, for which we may not be selected.
Many customers periodically solicit bids from multiple carriers for their shipping needs, which may depress freight rates or result in a loss of business to competitors.

The continuing trend toward consolidation in the trucking industry may result in more large carriers with greater financial resources and other competitive advantages, with which we may have difficulty competing.
Higher fuel prices and higher fuel surcharges to our customers may cause some of our customers to consider freight transportation alternatives, including rail transportation.
Competition from freight logistics and brokerage companies may negatively impact our customer relationships and freight rates.
Smaller carriers may build economies of scale with procurement aggregation providers, which may improve the smaller carriers’carriers' abilities to compete with us.
Our company strategy includes pursuing selected acquisitions; however, we may not be able to execute or integrate future acquisitions successfully.
Historically, a key component of our growth strategy has been to pursue acquisitions of complementary businesses, for example, the Central Acquisition. Although we currently do not have any additional acquisition plans, we expect to consider acquisitions in the future. Current or future acquisition and integration of target companies may negatively impact our business, financial condition, and results of operations because:
The business may not achieve anticipated revenue, earnings, or cash flows.
We may assume liabilities beyond our estimates or what was disclosed to us.
We may be unable to integrate successfully and realize the anticipated economic, operational, and other benefits in a timely manner, which could result in substantial costs and delays or other operational, technical, or financial problems.
The acquisition could disrupt our ongoing business, distract our management, and divert our resources.
We may have limited experience in the acquiree's market and may experience difficulties operating in its market.

There is a potential for loss of customers, employees, and drivers of the acquired company.
We may incur indebtedness or issue additional shares of stock.
Operational Risk
Consistent with industry trends, we face challenges with attracting and retaining qualified company drivers and owner-operators.
Recent driver shortages have required, and could continue to require, us to spend more for hiring, including recruiting and advertising. Our challenge with attracting and retaining qualified drivers stems from intense market competition, which subjects us to increased payments for driver compensation and owner-operator contracted rates. In 2014 and 2015,recent years, we increased these rates to better attract and retain drivers. To the extent that the economy improves, we expect that we would need to continue to increase driver compensation and owner-operator contracted rates in order to remain competitive. In addition to intense driver market conditions, proposed changes to regulations around drug and alcohol testing and corresponding compliance measures implemented by the Company may further challenge our ability to attract and retain qualified drivers.
Our high driver turnover rate (especially within 90 days of hire) requires us to continually recruit a substantial number of drivers in order to operate existing revenue equipment. If we do not attract and retain enough drivers, we could be forced to operate with fewer trucks. This would likely erode our size and profitability.
Our contractual agreements with owner-operators expose us to risks that we do not face with our company drivers.
Our financing subsidiaries offer financing to some of the owner-operators we contract with to purchase or lease tractors from us. If these owner-operators default or experience a lease termination in conjunction with these agreements and we cannot replace them, we may incur losses on amounts owed to us. Also, if liquidity constraints or other restrictions prevent us from providing financing to the owner-operators we contract with in the future, then we could experience a shortage of owner-operators. This would be detrimental to our efforts to maximize our capacity contracted out tofrom owner-operators.
Pursuant to our fuel reimbursement program with owner-operators, when fuel prices increase above a certain level, we share the cost with the owner-operators we contract with in order to mute the impact that increasing fuel prices may have on their business operations. A significant increase or rapid fluctuation in fuel prices could cause our reimbursement costs under this program to be higher than the revenue we receive from our customers under our customer fuel surcharge programs.
Owner-operators are third-party service providers, as compared to company drivers, who are employed by Swift. As independent business owners, the owner-operators we contract with may make business or personal decisions that conflict with the best interests of Swift. For example, if a load is unprofitable, route distance is too far from home, personal scheduling conflicts arise, or for other reasons, owner-operators may deny loads of freight from time to time. In these circumstances, Swift must be able to timely deliver the freight in order to maintain relationships with customers.

We depend on key personnel to manage our business and operations.
Our success depends on our ability to retain our executive officers, including Jerry Moyes (our founder and CEO), Richard Stocking (our President and COO),CEO) and Virginia Henkels (our CFO). Inadequate succession planning or unexpected departure of key executive officers could cause substantial disruption to our business operations, deplete our institutional knowledge base and erode our competitive advantage. We do not currently have employmentseverance protection agreements in place with anycertain members of our executive management including Mr. Moyes.team. We believe that the executive officers identified above possess valuable knowledge about the trucking industry and that their knowledge and relationships with our key customers and vendors would be very difficult to replicate. Although we believe we could replace key personnel, we may not be able to do so without incurring substantial costs.
Our ability to offer intermodal and brokerage services could be limited if we experience performance instability from third parties we use in those businesses.
Our intermodal business utilizes railroads and some third-party drayage carriers to transport freight for our customers. In most markets, rail service is limited to a few railroads or even a single railroad. Our ability to provide intermodal services in certain traffic lanes would be reduced or eliminated if the railroads' services became unstable. The cost of our rail-based services would likely increase, and the reliability, timeliness, and overall attractiveness of these services would likely decrease. Furthermore, railroads increase shipping rates as market conditions permit. Price increases could result in higher costs to our customers and negatively impact the demand for our intermodal services. In addition, we may not be able to negotiate additional contracts with railroads to expand our capacity, add additional routes, or obtain multiple providers, which could limit our ability to provide this service.
Our brokerage business is dependent upon the services of third-party capacity providers, including other truckload carriers.carriers that are our competitors. These third-party providers seek other freight opportunities and may require increased compensation in times of improved freight demand or tight trucking capacity. Our inability to secure the services of these third parties, or increases in the prices we must pay to secure such services, could have an adverse effect on our operations and profitability.

We are dependent on computer and communications systems; and a systems failure or data breach could cause a significant disruption to our business.
Our business depends on the efficient and uninterrupted operation of our computer and communications hardware systems and infrastructure. We currently maintain our computer system at our Phoenix, Arizona headquarters, along with computer equipment at each of our terminals. Our operations and those of our technology and communications service providers are vulnerable to interruption by fire, earthquake, natural disasters, power loss, telecommunications failure, terrorist attacks, Internet failures, computer viruses, data breaches (including cyber-attacks or cyber intrusions over the Internet, malware, and the like), and other events generally beyond our control. We mitigate the risk of business interruption by maintaining redundant computer systems, redundant networks, and backup systems at alternative locations. However, these alternative locations are subject to some of the same interruptions that may affect the Phoenix headquarters. In the event of a significant system failure, our business could experience significant disruption.
Seasonality, weather, and other catastrophic events affect our operations and profitability.
We discuss seasonality and weather events that affect our business in Part I, Item 1, under "Seasonality." These events and other catastrophic events may disrupt fuel supplies, increase fuel costs, disrupt freight shipments or routes, affect regional economies, damage or destroy our physical assets, or adversely affect the business or financial condition of our customers, any of which could harm our results or make our results more volatile.
Compliance Risk
Since our industry is highly regulated, we may inadvertently violate existing or future regulations or be adversely affected by changes to existing regulations.
We have the authority to operate in the continental United States (as granted by the DOT), Mexico (as granted by the Secretaría de Comunicaciones y Transportes), and various Canadian provinces (as granted by the Ministries of Transportation and Communications in such provinces). Our company, as well as our drivers and contracted owner-operators, must comply with enacted governmental regulations regarding safety, equipment, environmental protection, and operating methods. Examples include regulation of equipment weight, equipment dimensions, fuel emissions, driver hours-of-service, driver eligibility requirements, on-board reporting of operations, and ergonomics. We may also become subject to new or more restrictive regulations related to safety or operating methods. We discuss several proposed and pending regulations that could impact our operations in Part I, Item 1, under "Environmental Regulation," "Industry Regulation"Regulation," and "Other Regulation."
Additionally, our lease contracts with owner-operators are governed by the federal leasing regulations, which impose specific requirements on us and the owner-operators. In the past, we have been the subject of lawsuits, alleging the violation of lease agreements or failure to follow the contractual terms. It is possible that we could be subjected to similar lawsuits in the future, which could result in added liability.

If current or future legislation deems that owner-operators are equivalent to employees, we would incur more employee-related expenses.
Tax, federal, and other regulatory authorities have argued that owner-operators in the trucking industry are employees, rather than independent contractors. In April 2010, federal legislation was proposed that increased the recordkeeping requirements for companies that engage independent contractors and heightened the penalties to employers that misclassified individuals and violated overtime and/or wage requirements. Some states have put initiatives in place to increase their revenues from items such as unemployment workers’taxes, workers' compensation, and income taxes, and a reclassification of owner-operators as employees would help states achieve this objective. Further, class actions and other lawsuits have been filed against us and others in our industry seeking to reclassify owner-operators as employees for a variety of purposes, including workers’workers' compensation and health care coverage. Taxing and other regulatory authorities and courts apply a variety of standards in their determination of independent contractor status. If the owner-operators we contract with are deemed employees, we would incur additional exposure under laws for federal and state tax, workers’workers' compensation, unemployment benefits, labor, employment, and tort. The exposure could include prior period compensation, as well as potential liability for employee benefits and tax withholdings. In addition to that exposure, if owner-operators were deemed employees, then certain of our third-party revenue sources, including shop and insurance margins would be eliminated.
Changes in labor, wage, and other rules or legislation by the NLRB, Congress,or Congressstates, and/or organizing efforts by labor unions could result in litigation, divert management attention and have a material adverse effect on our operating results.
Although our only collective bargaining agreement exists at our Mexican subsidiary, Trans-Mex, we always face the risk that our employees will try to unionize. If the owner-operators we contract with were ever re-classified as employees, the magnitude of this risk would increase. The NLRB, Congress or states could impose rules or legislation significantly affecting our business and our relationship with our employees. On December 12, 2014, the NLRB implemented a final rule amending the agency's representation-case proceedings which govern the procedures for union representation. Pursuant to this amendment, union elections can now be held within 10-21 days after the union requests a vote. These new rules make it easier for unions to successfully organize all

20

SWIFT TRANSPORTATION COMPANY

employers, in all industries. Any attempt to organize by our employees could result in increased legal and other associated costs. In addition, if we entered into a collective bargaining agreement, the terms could negatively affect our costs, efficiency, and ability to generate acceptable returns on the affected operations.
In May of 2015, the Supreme Court of the United States refused to grant certiorari to Appelleesappellees in the United States Court of Appeals for the Ninth Circuit case, Dilts, et al. v. Penske Logistics, LLC, et al. Consequently, the Appeals Court decision stands, holding that California state wage and hour laws are not preempted by federal law. As a result, the trucking industry has been confronted with a continuous patchwork of laws at the state and local levels, related to employee rest and meal breaks. Further, driver piece rate compensation, which is an industry standard, has been attacked as not being compliant with state minimum wage laws. Both of these issues are adversely impacting the Company and the motor carrier industry as a whole, with respect to the practical application of the laws; thereby resulting in additional cost. In its individual capacity, as well as participating with industry trade organizations, the Company supports and is actively pursuing legislative relief through Congress. The Company believes enacting legislation clarifying the preemptive scope of federal transportation law and regulations, as originally contemplated by Congress, would eliminate much of the current wage and hour confusion along with lessening the burden on interstate commerce. The passage of federal legislation involves the political process and is uncertain. Existing state and local laws, as well as new laws adopted in the future, which are not preempted by federal law, may result in increased labor costs, driver turnover, reduced operational efficiencies, and amplified legal exposure.
CSA rulemaking could adversely affect us, including our ability to maintain or grow our fleet, as well as our customer relationships.
Under CSA, drivers and fleets are evaluated and ranked based on certain safety-related standards. The current methodology for determining a carrier’scarrier's DOT safety rating has been expanded, and as a result, certain current and potential drivers may no longer be eligible to drive for us. Additionally, our safety rating could be adversely affected. We recruit and retain a substantial number of first-time drivers. These drivers may have a higher likelihood of creating adverse safety events under CSA. A reduction in eligible drivers or a poor fleet ranking may result in difficulty attracting and retaining qualified drivers. This could cause our customers, some of which require a minimum safety rating, to transition to carriers with higher fleet rankings, and away from us.
Our captive insurance companies are subject to substantial government regulation.
Our captive insurance companies are regulated by state authorities. State regulations generally provide protection to policy holders, rather than stockholders, and generally involve:
approval of premium rates for insurance;
standards of solvency;
minimum amounts of statutory capital surplus that must be maintained;
limitations on types and amounts of investments;
regulation of dividend payments and other transactions between affiliates;
regulation of reinsurance;

19

Table of ContentsGlossary of Terms



SWIFT TRANSPORTATION COMPANY

regulation of underwriting and marketing practices;
approval of policy forms;
methods of accounting; and
filing of annual and other reports with respect to financial condition and other matters.
These regulations may increase our costs of regulatory compliance, limit our ability to change premiums, restrict our ability to access cash held in our captive insurance companies, and otherwise impede our ability to take actions we deem advisable.
We are subject to certain risks arising from doing business in Mexico.
We have a growing operation in Mexico, through our wholly-owned subsidiary, Trans-Mex, which subjects us to general international business risks, including:
foreign currency fluctuation;
changes in the economic strength of Mexico;
difficulties in enforcing contractual obligations and intellectual property rights;
burdens of complying with a wide variety of international and Unites States export, import, and business procurement laws;
changes in trade agreements and United States-Mexico relations; and
social, political, and economic instability.
In addition, if we are unable to maintain our C-TPAT status, we may have significant border delays. This could cause our Mexican operations to be less efficient than those of competitor truckload carriers that have C-TPAT status and operate in Mexico. We also

21

Table of ContentsGlossary of Terms



SWIFT TRANSPORTATION COMPANY

face additional risks associated with our foreign operations, including restrictive trade policies and imposition of duties, taxes, or government royalties imposed by the Mexican government, to the extent not preempted by the terms of the North American Free Trade Agreement.
Financial Risk
A material portion of our revenue is concentrated in a group of major customers. As such, we would be adversely affected if we lost one or more of these major customers.
Our revenue is concentrated in a group of major customers, as discussed in Part I, Item 1, under "Customers and Marketing." Retail and discount retail customers account for a substantial portion of our freight, creating a dependency on consumer spending and retail sales for us. Given this, our results may be more susceptible to trends in unemployment and retail sales than carriers that do not have this concentration.
Economic conditions and capital markets may adversely affect our customers and their ability to remain solvent. Our customers’customers' financial difficulties can negatively impact our results of operations and financial condition if they were to curtail their operations or delay or default on their payments to us. Aside from our Dedicated segment, we generally do not have contractual relationships that guarantee any minimum volumes with our customers, and we cannot provide assurance that our customer relationships will continue. Our Dedicated segment is generally subject to longer-term written contracts than our Truckload segment business; however, certain of these contracts contain cancellation clauses. If we lost one or more major customers, it could have a material impact on our results of operations and financial position. There is no assurance that any of our customers will continue to utilize our services, renew our existing contracts, or continue at the same volume levels.
We have significant ongoing capital requirements that necessitate sufficient cash flow from operations and/or obtaining financing on favorable terms.
The truckload industry is capital intensive. Historically, we have depended on cash from operations, borrowings from banks and finance companies, issuances of notes, and leasing activities to expand the size of our terminal network and upgrade and expand the size of our revenue equipment fleet.
Credit markets are likely tomay weaken again at some point in the future, which would make it difficult for us to access our current sources of credit and difficult for our lenders to find the capital to fund us. We may need to incur additional debt, or issue debt or equity securities in the future, to refinance existing debt, fund working capital requirements, make investments, or support other business activities. Declines in consumer confidence, decreases in domestic spending, economic contractions, and other trends in the credit market may impair our future ability to secure financing on satisfactory terms, or at all.
In the future, we could face inabilities with generating sufficient cash from operations, obtaining sufficient financing on favorable terms, or maintaining compliance with financial and other covenants in our financing agreements. If any of these events occur, then we may face liquidity constraints, be forced to enter into less favorable financing arrangements, or operate our revenue equipment for longer periods of time. Additionally, such events could adversely impact our ability to provide services to our customers.

Because our operations are dependent upon diesel fuel, fluctuations in price or availability, volume and terms of purchase commitments, and surcharge collection could materially increase our costs of operation.
Although fuel prices have recently decreased in recent periods, fuel is one of our largest operating expenses. Diesel fuel prices greatly fluctuate due to factors entirely beyond our control, such as political events, terrorist activities, armed conflicts, and depreciation of the dollar against other currencies. Hurricanes and other natural or man-made disasters, such as the oil spill in the Gulf of Mexico in 2010, tend to lead to an increase in the cost of fuel. Rising demand, matched with falling supply of fuel, adversely impacts the price. Examples include rising demand in developing countries like China, diminishing supply from less drilling activity, and sharing supply with industries using crude oil and oil reserves for other purposes. These events may lead to fuel shortages and disruptions in the fuel supply chain.
Fuel is also subject to regional pricing differences and often costs more on the West Coast and in the Northeast, where we have significant operations. Increases in fuel costs, to the extent not offset by rate-per-mile increases or fuel surcharges, have an adverse effect on our operations and profitability. We obtain some protection against fuel cost increases by maintaining a fuel-efficient fleet and compensatory fuel surcharge programs with the vast majority of our customers. These fuel surcharge programs have historically helped us offset the majority of any negative impacts of rising fuel prices associated with loaded or billed miles. Our fuel surcharge recovery lags behind changes in fuel prices. As such, it may not capture the increased costs we pay for fuel, especially when prices are rising. This leads to fluctuation in our levels of reimbursement, which has occurred in the past. During periods of low freight volumes, shippers can use their negotiating leverage to impose less robust fuel surcharge policies. We cannot ensure that such fuel surcharges will be indefinitely maintained or sufficiently effective. Additionally, there are certain fuel costs that we cannot recover, despite our fuel surcharge programs, such as those associated with deadhead miles and engine idling time.
We have not historically used derivatives to mitigate volatility in our fuel costs, but we periodically evaluate the benefits of employing this strategy. To mitigate the impact of rising fuel costs, we contract with some of our fuel suppliers to buy fuel at a fixed price or

22

Table of ContentsGlossary of Terms



SWIFT TRANSPORTATION COMPANY

within banded pricing for a specified period, usually not exceeding twelve months. However, these purchase commitments only cover a small portion of our fuel consumption. Accordingly, fuel price fluctuations may still negatively impact us.
We operate a modern fleet of tractors, some of which are leased or financed. This subjects us to costs associated with increasing equipment prices, new engine design changes, volatility in the used equipment sales market, and the failure of manufacturers to meet their sale or trade-back obligations.
Our modern fleet of tractors gives us a competitive advantage in many ways. However, there are also disadvantages we face from obtaining newer equipment. For example, engines used in tractors manufactured in 2010 and after are subject to more stringent emissions control regulations issued by the EPA. We have paid higher prices for new tractors over the past few years as a result of complying with these regulations, while the resale and residual values have not increased to the same extent. Accordingly, our equipment costs, including depreciation expense per tractor, are expected to increase in future periods. To comply with the EPA’sEPA's 2010 diesel engine emissions standards, many engine manufacturers are using special equipment that needs diesel exhaust fluid. If we purchase new tractors that have this special equipment, we will be exposed to additional costs associated with price and availability of diesel exhaust fluid, the weight of the equipment, maintenance, and training our drivers to use the equipment.
We have certain revenue equipment leases and financing arrangements with balloon payments at the end of the lease term equal to the residual value the Company is contracted to receive from certain equipment manufacturers upon sale or trade back to the manufacturers. If we do not purchase new equipment that triggers the trade-back obligation, or the equipment manufacturers do not pay the contracted value at the end of the lease term, we could be exposed to losses equal to the excess of the balloon payment owed to the lease or finance company over the proceeds from selling the equipment on the open market. In addition, if we purchase equipment subject to a buy-back agreement and the manufacturer refuses to honor the agreement, or we are unable to replace equipment at a reasonable price, we may be forced to sell the equipment at a loss.
Used equipment prices are subject to substantial fluctuations based on freight demand, supply of used trucks, availability of financing, presence of buyers for export to countries such as Russia and Brazil, and commodity prices for scrap metal. These and any impacts of a depressed market for used equipment could require us to tradedispose of our revenue equipment below the carrying value. This leads to losses on disposal or impairments of revenue equipment, when not otherwise protected by residual value arrangements. Deteriorations of resale prices or trades at depressed values could cause more losses on disposal or impairment charges in future periods.
Our substantial leverage could adversely affect our ability to raise additional capital to fund our operations, limit our ability to react to changes in the economy or our industry, and prevent us from meeting our debt obligations.
As of December 31, 2015,2016, our total outstanding long-term debt, including outstanding borrowings on the New Revolver and 2015 RSA, but excluding capital lease obligations, was $1.1$0.9 billion. SinceBecause we are substantially leveraged, we could be at a competitive disadvantage compared to our competitors that are less leveraged. This could have negative consequences that include:
increased vulnerability to adverse economic, industry, or competitive developments;
cash flows from operations that are committed to payment of principal and interest, thereby reducing our ability to use cash for our operations, capital expenditures, and future business opportunities;

21

Table of ContentsGlossary of Terms



SWIFT TRANSPORTATION COMPANY

increased interest rates that would affect our variable rate debt;
noncompliance with restrictive covenants, borrowing conditions, and other debt obligations, which could result in an event of default;
non-strategic divestitures or inability to make strategic acquisitions;
lack of financing for working capital, capital expenditures, product development, debt service requirements, acquisitions, and general corporate or other purposes; and
limits on our flexibility to plan for, or react to, changes in our business, market conditions, or in the economy.
Our debt agreements contain restrictions that limit our flexibility in operating our business.
As detailed in Note 1213 to the consolidated financial statements, our senior secured credit facility agreement requires compliance with various affirmative, negative, and financial covenants. A breach of any of these covenants could result in default or (when applicable) cross-default. Upon default under our senior secured credit facility, the lenders could elect to declare all outstanding amounts to be immediately due and payable, as well as terminate all commitments to extend further credit. Such actions by those lenders could cause cross defaults with our other debt agreements. If we were unable to repay those amounts, the lenders could secure the debt with the collateral granted to them. If the lenders accelerated our debt repayments, we might not have sufficient assets to repay all amounts borrowed.
In addition, our 2015 RSA includes certain restrictive covenants and cross default provisions with respect to our senior secured credit facility. Failure to comply with these covenants and provisions may jeopardize our ability to continue to sell receivables under the facility and could negatively impact our liquidity.

Insuring risk through our captive insurance companies could adversely impact our operations.
We insure a significant portion of our risk through our captive insurance companies, Mohave and Red Rock. In addition to insuring portions of our own risk, Mohave provides reinsurance coverage to third-party insurance companies associated with our affiliated companies' owner-operators. Red Rock insures a share of our automobile liability risk. The insurance and reinsurance markets are subject to market pressures. Our captive insurance companies’companies' abilities or needs to access the reinsurance markets may involve the retention of additional risk, which could expose us to volatility in claims expenses.
To comply with certain state insurance regulatory requirements, cash and cash equivalents must be paid to Red Rock and Mohave as capital investments and insurance premiums, to be restricted as collateral for anticipated losses. The restricted cash is used for payment of insured claims. In the future, we may continue to insure our automobile liability risk through our captive insurance subsidiaries, which will cause increases in the required amount of our restricted cash or other collateral, such as letters of credit. Significant increases in the amount of collateral required by third-party insurance carriers and regulators would reduce our liquidity.
We face risks related to self-insurance and third-party insurance that can be volatile to our earnings.
We self-insure a significant portion of our claims exposure and related expenses for cargo loss, bodily injury, workers’workers' compensation, and property damage, and maintain insurance with insurance companies above our limits of self-insurance. Self-insurance retention and other limitations are detailed in Part I, Item 1, under "Safety and Insurance." Our large self-insured retention limits can make our insurance and claims expense higher or more volatile. Additionally, if our third-party insurance carriers or underwriters leave the trucking sector, it could materially increase our insurance costs or collateral requirements, or create difficulties in finding insurance in excess of our self-insured retention limits.
We accrue for the costs of the uninsured portion of pending claims, based on the nature and severity of individual claims and historical claims development trends. Estimating the number and severity of claims, as well as related judgment or settlement amounts is inherently difficult. This, along with legal expenses, incurred but not reported claims, and other uncertainties can cause unfavorable differences between actual self-insurance costs and our reserve estimates. We try to limit our exposure to claims that ultimately prove to be more severe than originally assessed. However, this may not be possible if carrier subcontractors under our brokerage operations are inadequately insured for any accident.
Although we believe our aggregate insurance limits are sufficient to cover reasonably expected claims, it is possible that one or more claims could exceed those limits. In this case, we would bear the excess expense, in addition to the amount of self-insurance. Our insurance and claims expense could increase, or we could find it necessary to raise our self-insured retention or decrease our aggregate coverage limits when our policies are renewed or replaced.
Our stock price has recently declined and could continue to decline due to the large number of outstanding shares of our common stock eligible for future sale.
Sales of substantial amounts of our common stock in the public market, or the perception that these sales could occur, could cause the market price of our Class A common stock to decline. These sales also could make it more difficult for us to sell equity or equity- related securities in the future at a time and price that we deem appropriate.

SWIFT TRANSPORTATION COMPANY

As of December 31, 2015,2016, we have approximately 87.883.3 million outstanding shares of Class A common stock, assuming no exercise of options outstanding as of the date of this report, and approximately 51.049.7 million outstanding shares of Class B common stock that are convertible into an equal number of shares of Class A common stock. All of the Class A shares are freely tradable, except that any shares owned by "affiliates" (as that term is defined in Rule 144 under the Securities Act) may only be sold in compliance with the limitations described in Rule 144 under the Securities Act.
In addition, we have an aggregate of 4.94.3 million shares and 1.81.7 million shares of Class A common stock reserved for issuances under our 2014 Omnibus Incentive Plan and our 2012 Employee Stock Purchase Plan, respectively. Issuances of Class A common stock to our directors, executive officers, and employees through exercise of stock options under our stock plans, or purchases by our executive officers and employees through our 2012 ESPP, dilute a stockholder's interest in Swift.
We could determine that our goodwill and other indefinite-lived intangibles are impaired, thus recognizing a related loss.
As of December 31, 2015,2016, we had goodwill of $253.3 million and indefinite-lived intangible assets of $181.0 million primarily from the 2007 Transactions. We evaluate goodwill and indefinite-lived intangible assets for impairment in accordance with the accounting policies discussed in Note 2 to the consolidated financial statements. Our evaluations in 2016, 2015, 2014 and 20132014 produced no indication of impairment. We could recognize impairments in the future, and we may never realize the full value of our intangible assets. If these events occur, our profitability and financial condition will suffer.
We do not currently intend to pay dividends on our Class A common stock or Class B common stock.
We do not currently anticipate paying cash dividends on our Class A common stock or Class B common stock in the near future. We anticipate that we will retain all of our future earnings, if any, for use in the development and expansion of our business, the repayment of debt, our repurchase of our Class A common stock, and for general corporate purposes. Any determination to pay dividends and other distributions in cash, stock, or property by Swift in the future will be at the discretion of our Board and will be dependent on then-existing conditions, including our financial condition and results of operations, contractual restrictions, such as restrictive covenants contained in our senior secured credit facility, capital requirements, legal restrictions, and other factors.

Conflict of Interest Risk
Our controlling shareholder and CEO,Board member, Jerry Moyes, along with the Moyes Affiliates, control a large portion of our stock and have substantial control over us, which could limit other stockholders’stockholders' ability to influence the outcome of key transactions, including changes of control.
Our CEO,controlling shareholder and Board member, Mr. Moyes, and the Moyes Affiliates beneficially own approximately 39%40.3% of our outstanding common stock. Mr. Moyes and the Moyes Affiliates beneficially own 100%100.0% of our Class B common stock and approximately 3%4.6% of our Class A common stock. On all matters with respect to which our stockholders have a right to vote, including the election of directors, the holders of our Class A common stock are entitled to one vote per share, and the holders of our Class B common stock are entitled to two votes per share. All outstanding shares of Class B common stock are convertible to Class A common stock on a one-for-one basis at the election of the holders thereof, or automatically upon transfer to someone other than Mr. Moyes or the Moyes Affiliates.
This voting structure gives Mr. Moyes and the Moyes Affiliates approximately 55%56.5% of the voting power of all of our outstanding stock as of December 31, 2015. Furthermore, due to2016. As a result of our dual class structure, Mr. Moyes and the Moyes Affiliates are able to control all matters submitted to our stockholders for approval even though they own less than 50% of the total outstanding shares of our common stock. This significant concentration of share ownership may adversely affect the trading price for our Class A common stock because investors may perceive disadvantages in owning stock in companies with controlling stockholders. Also, these stockholders can exert significant influence over our management and affairs and matters requiring stockholder approval, including the election of directors and the approval of significant corporate transactions, such as mergers, consolidations, or the sale of substantially all of our assets. Consequently, this concentration of ownership may have the effect of delaying or preventing a change of control, including a merger, consolidation, or other business combination involving us, or discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control, even if other stockholders perceived that change of control to be beneficial.
Because Mr. Moyes and the Moyes Affiliates control a majority of the voting power of our common stock, we qualify as a "controlled company" as defined by the NYSE and as such, we may elect not to comply with certain corporate governance requirements of this stock exchange. We do not currently intend to utilize these exemptions, but may choose to do so in the future.
Mr. Moyes has borrowedloans and other obligations against which he and certain of his family members have pledged a portion of histheir Class B common stock,which may cause a conflict of interests between himMr. Moyes and our other stockholders, and adversely affect the trading price of our Class A CommonStock.
Cactus II Pledging —In July 2011 and December 2011, Cactus Holding Company II, LLC ("Cactus II"), an entity controlled by Mr. Moyes, pledged 12,023,343 shares of Class B common stock on margin as collateral for personal loan arrangements entered into by Cactus II and relating to Mr. Moyes. In connection with these December 2011 transactions, Cactus II converted 6,553,253 of the 12,023,343 pledged shares of Class B common stock into shares of Class A common stock on a one-for-one basis. During

2012, the Moyes Affiliates converted an additional 1,068,224 shares of Class B common stock to Class A common stock and sold 4,831,878 of these pledged Class A shares to a counter-party pursuant to a sale and repurchase agreement with a full recourse obligation to repurchase the securities at the same price on the fourth anniversary of sale. As of December 31, 2015, the Moyes Affiliates had pledged on margin 9,140,167 shares, of which 6,550,090 were Class B and 2,590,077 were Class A common stock. These pledged shares could cause Mr. Moyes’ interest to conflict with the interests of our other stockholders and could result in the future sale of such shares. Such sales could adversely affect the trading price or otherwise disrupt the market for our Class A common stock.
M Capital II VPF In addition to the shares that were allowed to be pledged on margin pursuant to our second amended and restated securities trading policy, on October 29, 2013, an affiliate of Mr. Moyes ("M Capital II") entered into a VPF contract with Citibank, N.A. that was intended to facilitate settlement of the 2010 METS, issued in 2010 by an unaffiliated trust concurrently with the Company’s IPO, which was required to be settled with shares of the Company’s Class A common stock, or cash, on December 31, 2013. This transaction effectively replaced the 2010 METS with the VPF contract and allowed the parties to the 2010 METS transaction to satisfy their obligations under the 2010 METS (as contemplated by their terms) without reducing the number of shares owned by these parties. The VPF transaction allowed Mr. Moyes and certain of his affiliates, through their ownership of M Capital II, to participate in future price appreciation of the Company’s Common Stock, and retain the voting power of the shares collateralized to secure the VPF contract. Under the VPF contract, M Capital II was obligated to deliver to Citibank a variable amount of stock or cash during two twenty trading day periods beginning on January 4, 2016, and July 5, 2016, respectively.
Amended M Capital II VPF and Cactus VPF On October 30, 2015, M Capital II and another Moyes Affiliate, Cactus Holding I, entered into the Amended M Capital II VPF and the Cactus VPF, respectively. The purposes of these two VPF contracts were to (i) extend the maturity date of M Capital II’sII's then-existing VPF with Citibank N.A. (discussed above)entered into on October 29, 2013 and maturing on November 4, 2015 through November 6, 2015 and (ii) generate cash proceeds for the repayment of certain stock-secured obligations of Cactus Holding II, a Moyes Affiliate, and thereby effect the release of certain shares of Class B Common Stockcommon stock pledged in connection with the same.
Cactus Holding I entered into the Cactus VPF contract in respect of 3,300,0003.3 million shares of the Company's Class B Common Stock,common stock, which were pledged by Cactus Holding I as security for its obligations under the Cactus VPF contract. Under the Cactus VPF contract, Cactus Holding I iswas required to deliver to Citigroup Global Markets Inc. ("CGMI") a variable amount of stock or cash during a three trading day period at the maturity of the contract on November 21, 2016 through November 24, 2016.2016 (later extended to November 25, 2016, then extended to 2017 as described below). In connection with the Cactus VPF contract, Cactus Holding I received $48.3 million from CGMI.CGMI (including the $18.5 million noted in the paragraph below).
In connection with the Amended M Capital II VPF, M Capital II paid Citibank N.AN.A. $18.5 million. The source of these funds was a cash payment from CGMI in connection with the Cactus VPF Contract. Under the Amended M Capital II VPF contract, M Capital II iswas required to deliver to Citibank N.A. a variable amount of stock or cash during a three trading day period at the maturity of the contract on November 21, 2016 through November 24, 2016.2016 (later extended to November 25, 2016, then extended to 2017 as described below). The number of shares of the Company's Class B Common Stockcommon stock subject to the Amended M Capital II VPF remainsremained unchanged at 13,700,000.13.7 million.
The AmendedOn May 18, 2016, M Capital II terminated its VPF covering approximately12.3 million shares of Class A common stock, and entered into a new VPF covering approximately 12.3 million shares of Class A common stock. The new VPF required M Capital II to deliver a variable amount of Class A common stock, up to a maximum of approximately 12.3 million shares, or an equivalent amount of cash, upon maturity dates occurring on May 26, 2017 through May 31, 2017. The new VPF is collateralized by approximately 12.3 million shares of Class B common stock.
Also on May 18, 2016, Cactus Holding I entered into a new VPF covering approximately 7.0 million shares of Class A common stock. The new VPF required Cactus Holding I to deliver a variable amount of Class A common stock, up to a maximum of approximately 7.0 million shares, or an equivalent amount of cash, upon maturity dates occurring on May 26, 2017 through May 31, 2017. The new VPF is collateralized by an aggregate of approximately 7.0 million shares of Class A common stock and Class B common stock which were previously pledged on margin.

On November 18, 2016, the maturity dates of the M Capital II VPFs were extended to December 5, 2017 through January 3, 2018, and the maturity dates of the Cactus Holding I VPFs were extended to December 5, 2017 through December 7, 2017. No additional shares were pledged in connection with these extensions.
The VPF contracts allow Mr. Moyes and the Moyes Affiliates to retain the same number of shares and voting percentage as they had prior to these VPF contracts. In addition, Mr. Moyes and the Moyes Affiliates are able to participate in any price appreciation of the Company’s common stock. The Amended M Capital II VPF Contract generally permits M Capital II to participate in any price appreciation in the Company’s common stock between $22.00 and $26.40 per share. Under the then-existing VPF, M Capital II was generally permitted to participate in any price appreciation in the Company's common stock between $22.54 and $34.00 per share. The Cactus VPF Contract generally permits Cactus Holding I to participate in any price appreciation in the Company's common stock between $22.00 and $26.40 per share.within certain levels.
In connection with the Amended M Capital II VPF transaction, 25,994,016transactions described above, an aggregate of approximately 34.3 million shares of Class B Common Stockcommon stock and approximately 2.0 million shares of Class A common stock are collateralized by Citibank, N.A. to secure M Capital II’sII's and Cactus Holding I's respective obligations under the VPF Contract.  transactions.
As these shares are not pledged to secure a loan on margin, they are not subject to the securities trading policy pledging limitation discussed below. Although M Capital II and Cactus Holding I, respectively, may settle itstheir obligations to Citibank N.A.under the VPF transactions in cash, any or all of the collateralized Class B common stock shares could be converted into Class A common stock and any of the collateralized shares delivered on such dates to settle such obligations. Such transfers of our common stock, or the perception that they may occur, may have an adverse effect on the trading price of our Class A common stock and may create conflicts of interest for Mr. Moyes. In addition, Mr. Moyes’ counter party to the VPFs hedges their position by borrowing shares of Class A common stock and subsequently selling such shares, creating a short position. This hedging activity will fluctuate from time to time, based on the current market price of the Class A common stock and the counter party's strategy for reducing risk in their position. This hedging activity may place additional pressure on the price of the Class A common stock as such short positions are being put in place and/or may create a perception that the market is questioning Swift’s performance given the large short position that can occur and be reported. Maintaining this short position may offset some of the risk associated with a full share settlement of the VPF transactions as any shares received by the counter party might be used to settle these short positions thus reducing the amount that would otherwise be introduced to the market.
Cactus II Pledging —In July 2011 and December 2011, Cactus Holding Company II, LLC ("Cactus II"), an entity controlled by Mr. Moyes, pledged approximately 12.0 million shares of Class B common stock on margin as collateral for loan arrangements entered into by Cactus II and relating to Mr. Moyes. In connection with these December 2011 transactions, Cactus II converted approximately 6.6 million of the approximately 12.0 million pledged shares of Class B common stock into shares of Class A common stock on a one-for-one basis. During 2012, the Moyes Affiliates converted an additional approximately 1.1 million shares of Class B common stock to Class A common stock and sold approximately 4.8 million of these pledged Class A shares to a counter-party pursuant to a sale and repurchase agreement with a full recourse obligation to repurchase the securities at the same price on the fourth anniversary of sale.
This sale and repurchase agreement was replaced in May 2014 with a similar sale and repurchase agreement covering approximately 6.8 million shares. On May 18, 2016 the maturity of this agreement was extended to May 30, 2017, and was extended again on November 18, 2016 to November 30, 2017. On May 18, 2016, 2.0 million shares of Class A common stock and 5.1 million shares of Class B common stock previously pledged on margin for collateral for loan arrangements were transferred to a new VPF agreement as described above. On July 20, 2016, Cactus Holding II pledged an incremental approximately 1.9 million shares as collateral for a new loan arrangement. As of August 2, 2016, the Moyes Affiliates had pledged on margin a total of approximately 4.1 million shares, of which approximately 2.2 million were Class B and approximately 1.9 million were Class A common stock.
These pledged shares could cause Mr. Moyes’ interest to conflict with the interests of our other stockholders and could result in the future sale of such shares. Such sales could adversely affect the trading price or otherwise disrupt the market for our Class A common stock.
Other Obligations —On April 20, 2016, Mr. Moyes entered into a settlement agreement with the National Hockey League ("NHL") relating to a previously disclosed lawsuit between the NHL and Mr. Moyes. As part of the settlement agreement, certain of Mr. Moyes’ adult children entered into a Non-Recourse Guaranty and Pledge Agreement with the NHL pursuant to which they guaranteed certain obligations of Mr. Moyes and certain Moyes Affiliates to the NHL. The guarantor’s obligations are collateralized by 2.0 million shares of Class B common stock owned by the guarantors.
Margin Pledging Limitations — The Company has a securities trading policy ("STP") that includes, among other things, limitations on the pledging of Company stock on margin. As disclosed at the time of our IPO, under the STP, directors, senior executive officers (including the CEO), and compliance officers were not permitted to pledge more than 20% of their family stock holdings for margin loans. In July 2013, the Nominating and Governance Committee and the Board approved revisions to the STP to further limit pledging of stock on margin, under which, effective July 1, 2014, the limitation was reduced to 15% of family stock holdings and was scheduled to be reduced to 10% of family stock holdings as of July 1, 2015.
In June 2015, our CEOthen-Chief Executive Officer, Jerry Moyes, reported to the independent chairman of the boardBoard that he was in compliance with the limitation on pledging stock on margin and was working to reduce the amount pledged on margin to below the 10% limit scheduled to take effect, but needed until November 2015 to do so in an orderly fashion. Following Board discussion of these circumstances, the Board amended the STP so that the 15% limit would remain in effect through November 30, 2015 and the 10% limit would take effect on December 1, 2015.

SWIFT TRANSPORTATION COMPANY

In October 2015, our CEOMr. Moyes informed the Company that due to the drop in the stock price he had pledged additional shares of Company stock on margin in August and September 2015, in contravention of the STP, and that the percentage of family stock holdings pledged on margin was in excess of the 15% limit. He was precluded from selling shares during this time sincebecause he was in possession of material non-public information.
The independent members of the Board met and considered these events in light of competing concerns. On the one hand, the policy and limitations on pledging stock on margin were intended to avoid the risks of stock being sold to satisfy a margin call at a time when Company insiders might have material nonpublic information. On the other hand, unwinding margin positions in significant amounts in a short period could generate adverse market perceptions concerning the Company and the stock. In addition, the Board sought additional information regarding the CEO’sMr. Moyes' plans to reduce the level of stock pledged on margin.
In response to these developments and the competing concerns identified, the Board directed the CEOMr. Moyes to reduce the level of stock pledged on margin to 15% or less of family holdings no later than November 4, 2015 and determined to waive compliance with the 10% limit (but not the 15% limit) through December 31, 2016 so that the margin positions could be reduced in an orderly fashion. In addition, the Board formally reprimanded the CEOMr. Moyes and imposed sanctions.
The Company's recent stock price volatility hascontinued in December 2015 and necessitated Mr. Moyes to increase the level of Company stock pledged on margin; thereby exceeding the 15% limit. Taking into account various competing concerns, on December 18, 2015, the Board determined to waive compliance with the 15% limit (but not the 20% limit) through December 31, 2016 to allow Mr. Moyes to reduce the margin position in an orderly manner.
After giving effect to the amendments and waivers discussed above, the current STP provides that directors, senior executive officers (including the CEO), and compliance officers are not permitted to pledge more than 20% of their family stock holdings for margin loans through December 31, 2016, reducing to 15% of family stock holdings through December 31, 2017 and 10% of family stock holdings after January 1, 2018.
Mr. Moyes' consulting contract with Swift, effective December 31, 2016, contains a clause that addresses his hedging and pledging transactions. With respect to these transactions, so long as Mr. Moyes remains an officer or director of the Company, those transactions are generally required to be conducted in accordance with the Company's STP, effective as of August 31, 2016. As such, Board approval is required prior to Mr. Moyes conducting any such transactions. Pursuant to the consulting contract, the Company has agreed to take reasonable and prompt action (including Board consideration and submission of customary transfer agent and similar letters and confirmations) to permit the Moyes Affiliates to effect such transactions.
We engage in transactions with other businesses controlled by ourCEO, majority shareholder and Board member, Jerry Moyes. This could create conflicts of interest between Mr. Moyes and our other stockholders.
We engage in various transactions with companies controlled by and/or affiliated with related parties. These transactions include freight services, facility leasing, air transportation, and other services provided by and/or received by Swift with entities affiliated with Mr. Moyes. Because certain entities controlled by Mr. Moyes and certain members of his family operate in the transportation industry, Mr. Moyes’Moyes' ownership may create conflicts of interest or require judgments that are disadvantageous to our stockholders in the event we compete for the same freight or other business opportunities. As a result, Mr. Moyes may have interests that conflict with our stockholders.
We have adopted a policy that requires prior approval of related party transactions. Additionally, our amended and restated certificate of incorporation contains provisions that specifically relate to prior approval of related party transactions with Mr. Moyes, the Moyes Affiliates, and any Moyes affiliatedMoyes-affiliated entities. However, we cannot provide assurance that the policy or these provisions will be successful in eliminating conflicts of interest. Our amended and restated certificate of incorporation also provides that in the event that any Swift officer or director is also an officer, director, or employee of an entity owned by (or affiliated with) Mr. Moyes (or any Moyes Affiliate) and acquires knowledge of a potential transaction or other corporate opportunity not involving the transportation industry or involving refrigerated or LTL transportation, then, subject to certain exceptions, we shall not be entitled to such transaction or corporate opportunity and there should be no expectancy that such transaction or corporate opportunity will be available to us.
Mr. Moyes, our CEO,majority shareholder and Board member, has substantial ownership interests in and guarantees related to several other businesses and real estate investments, which may expose Mr. Moyes to significant lawsuits or liabilities.
In addition to being our CEOmajority shareholder and principal stockholder,Board member, Mr. Moyes is the principal stakeholder of, and serves as chairman of the board of directors of SME Industries, Inc., a steel erection and fabrication company, Southwest Premier Properties, LLC, a real estate management company, and is involved in other business endeavors in a variety of industries and has made substantial real estate investments. Although Mr. Moyes devotes the substantial majority of his time to his role as CEO of Swift, the breadth of Mr. Moyes’ other interests may place competing demands on his time and attention.
In addition, in one instance of litigation arising from another business owned by Mr. Moyes, Swift was named as a defendant even though Swift was not a party to the transactions that were the subject of the litigation. It is possible that litigation relating to other businesses owned by Mr. Moyes in the future may result in Swift being named as a defendant and, even if such claims are without merit, that we will be required to incur the expense of defending such matters. In many instances, Mr. Moyes has given personal guarantees to lenders to the various businesses and real estate investments in which he has an ownership interest and, in certain cases, the underlying loans are in default and are in the process of being restructured and/or settled. If Mr. Moyes is otherwise unable to settle

Executive Summary
Company Overview — Swift is a multi-faceted transportation services company, operating one of the largest fleets of truckload equipment in North America from over 40 terminals near key freight centers and traffic lanes. We principally operate in short- to medium-haul traffic lanes around our terminals and dedicated customer locations. We concentrate on this length of haul because the majority of domestic truckload freight (as measured by revenue) moves in these lanes and our extensive terminal network affords us marketing, equipment control, supply chain, customer service, and driver retention advantages in local markets. Since our average length of haul is relatively short, it helps reduce competition from railroads and trucking companies that lack a regional presence.
Our four reportable segments are Truckload, Dedicated, Swift Refrigerated, and Intermodal. Our extensive suite of service offerings (which includes line-haul services, dedicated customer contracts, temperature-controlled units, intermodal freight solutions, cross-border United States/Mexico and United States/Canada freight, flatbed hauling, freight brokerage and logistics, and others) provides our customers with the opportunity to "one-stop-shop" for their truckload transportation needs. In 2015,2016, our tractor fleet (included in the total equipment schedule, below) covered 2.2 billion miles for shippers throughout North America.
Revenue — In 2015,2016, we generated consolidated operating revenue of $4.2$4.0 billion. We primarily generate revenue by transporting freight for our customers, generally at a predetermined rate per mile. We supplement this revenue by charging for fuel surcharges, stop-off pay, loading and unloading activities, tractor and trailer detention, and other ancillary services. The main factors that affect our revenue from transporting freight are the rate per mile we receive from our customers and loaded miles. The main factors that affect fuel surcharge revenue are the price of diesel fuel and the number of loaded miles. Fuel surcharges are billed on a lagging basis, meaning that we typically bill customers in the current week based on a previous week's applicable index. Therefore, in times of increasing fuel prices, we do not recover as much as we are currently paying for fuel. In periods of declining prices, the opposite is true.
Revenue in our non-reportable segmentsegments is generated by our non-asset-based freight brokerage and logistics management service, tractor leasing revenue from our financing subsidiaries, premium revenue from our captive insurance companies, and revenue from third parties serviced by our repair and maintenance shops. Main factors affecting revenue in our non-reportable segment are demand for brokerage and logistics services, as well as the number of equipment leases by our financing subsidiaries to the owner-operators we contract with and other third parties.
Expenses — Our most significant expenses vary with miles traveled and include fuel, driver-related expenses (such as wages and benefits), and services purchased from owner-operators and other transportation providers (such as railroads, drayage providers, and other trucking companies). Maintenance and tire expenses, as well as cost of insurance and claims generally vary with the miles we travel, but also have a controllable component based on safety improvements, fleet age, efficiency, and other factors. Our primary fixed costs are depreciation and lease expense for revenue equipment and terminals, interest expense, and non-driver compensation.
Compared to changes in rate per mile and loaded miles, changes in deadhead miles percentage generally have the largest proportionate effect on our profitability because we still bear all of the expenses for each deadhead mile, but do not earn any revenue to offset those expenses. Changes in rate per mile have the next largest proportionate effect on profitability because incremental improvements in rate per mile are not offset by any additional expenses. Changes in loaded miles generally have a smaller effect on profitability because variable expenses fluctuate with changes in miles. However, changes in mileage are affected by driver satisfaction and network efficiency, which indirectly affect expenses.
2016 Initiatives —The truckload freight environment in 2016 was challenging. Excess industry capacity, excess customer inventories, and depressed shipping demand pressured volumes and pricing. We implemented the following initiatives to help counter the effects of these external factors:
We downsized our core truckload fleet in an effort to improve asset utilization, and we continue to closely monitor and adjust our truckload fleet size to ensure proper utilization of our fleets.
We selectively increased our participation in the spot market to improve network balance and help offset the lack of available freight in certain markets. Our sales team remains heavily focused on increasing freight levels with both new and existing customer contracts, with the goal of eventually reducing our spot market activity.
We implemented several cost control initiatives throughout the organization, which include streamlining processes, reducing headcount, postponing non-critical system implementations, and reducing expenses in various other manners.

These non-GAAP financial measures should not be considered alternatives, or superior, to GAAP financial measures. However, management believes that presentation of these non-GAAP financial measures provides useful information to investors regarding the Company's results of operations. Adjusted EBITDA,EPS, Adjusted Operating Ratio, and Adjusted EPSEBITDA are reconciled to the most directly comparable GAAP financial measures under "Non-GAAP Financial Measures," below.

Factors Affecting Comparability Between Periods
Driver Wages and Owner-operator Pay Rates — We implemented increases in wages for our company drivers and contracted pay rates for the owner-operators we contract with in August 2014 and May 2015. These increases were tailored, and we believe successful, at improving driver retention and recruiting. However, the increases are havinghad a short-term negative impact on profitability for certain periods discussed below, given the immediate effect of driver wage and pay rate increases on expense, versus the more gradual effect of customer pricing increases on revenue. We refer to these increases in company driver wages and owner-operator contracted pay rates throughout the segment and operating expense reviews, below.
Results of Operations — Comparison Between the Years Ended December 31, 2015 and December 31, 2014
Net income in 2015 was $197.6 million, compared to $161.2 million in 2014. The following factors affected comparability between 2015 and 2014:
$41.7 million decrease in interest expense, primarily driven by the call of our Senior Notes in November 2014.
$9.6 million loss on debt extinguishment in 2015 from replacing the 2014 Agreement with the 2015 Agreement, compared to $39.9 million loss on debt extinguishment in 2014 ($34.7 million from redeeming our Senior Notes and $5.2 million from replacing the 2013 Agreement with the 2014 Agreement).
$29.7 million increase in income tax expense, driven by an increase in income before income taxes and an increase in the effective tax rate from 35.7% in 2014 to 37.6% in 2015.
$20.3 million increase in insurance and claims expense, primarily due to the first three quarters in 2015, when we had adverse current-year development of certain prior-year claims, higher claims severity trends and higher claims frequency trends. However, our crash frequency and severity trends improved in the fourth quarter of 2015, partially driven by our investments in new equipment with enhanced safety features, as well as improved driver retention and other safety initiatives.
$13.5 million additional depreciation, maintenance and staging expense, resulting from the backlog of trucks that were being processed for trade or sale in the latter half of 2015.
$6.0 million non-operating expense for a lawsuit that was settled in June 2015.
$5.1 million operating expense for settlement of a class action lawsuit and related items in 2015.
$1.5 million pre-tax impairment of a non-operating note receivable in 2015. The note was due to the Company from an independent fleet contractor, transporting freight on behalf of Swift.
$2.3 million impairment of certain operations software in 2014.
Results of Operations — Comparison Between the Years Ended December 31, 20142016 and December 31, 20132015
NetThe $48.3 million decrease in net income in 2014 was $161.2 million, compared to $155.4from $197.6 million in 2013. The following factors affected comparability between 2014 and 2013:
$39.9 million loss on debt extinguishment in 2014, discussed above, compared2015 to a $5.5 million loss on debt extinguishment in 2013 ($5.0 million from replacing the 2012 Agreement with the 2013 Agreement and $0.5 million from repaying certain outstanding Central debt in full at closing of the Central Acquisition).
$19.5 million reduction in interest expense in 2014, compared to 2013, primarily due to redeeming our Senior Notes, lowering our debt balances, and replacing the 2013 Agreement with the 2014 Agreement.
280 basis point difference in the effective tax rate, which was 35.7% in 2014, compared to the expected effective tax rate of 38.5%, primarily due to the benefit of prior year federal income tax credits realized in the third quarter of 2014 and federal employment income tax credits realized in the fourth quarter of 2014.
$3.0$149.3 million in pre-tax gain on disposal of redundant Central properties in 2014.2016, reflects the following:
(1)$59.1 million decrease in Revenue xFSR — This was driven by decreases in the Truckload, Swift Refrigerated, Intermodal, and non-reportable segments, partially offset by an increase in Revenue xFSR in the Dedicated segment.
(2)$138.7 million decrease in fuel surcharge revenue — Fuel prices were lower overall in 2016, which had an average DOE index of $2.30, compared to $2.71 in 2015.
(3)$71.5 million decrease in fuel expense, primarily due to lower fuel prices.
(4)$63.7 million decrease in purchased transportation — The decrease in the expense was attributed to reduced fuel reimbursements to owner-operators, as a result of lower fuel prices and a 2.9% decrease in miles driven by owner-operators. Additionally, lower intermodal freight volumes resulted in a decrease in payments to rail carriers, further contributing to the decrease in the expense. This was partially offset by the impact of increasing owner-operator contracted pay rates in May 2015.
(5)$36.7 million increase in salaries, wages, and employee benefits, which was primarily due to the driver wage increase implemented in May 2015, an increase in group health insurance expenses, and a $7.1 million one-time expense pertaining to Jerry Moyes' retirement package.
(6)$14.2 million decrease in gain on disposal of property and equipment, primarily driven by lower gain on disposals of tractors, due to a soft used truck market in 2016, compared to 2015. This was partially offset by an increase in volume of trailers sold.
(7)$9.6 million loss on debt extinguishment in 2015, resulting from the replacement of the 2014 Agreement with the 2015 Agreement.
(8)$53.5 million decrease in income tax expense. The effective tax rate in 2016 was 30.6%, which was lower than our expectation of 36.5%. The difference reflects reduced taxes primarily due to a reduction of income before income taxes. Additionally, federal domestic production activities deductions, certain income tax credits received by our foreign and domestic subsidiaries, and a reduction in our uncertain tax position reserve contributed to the difference. See below for discussion related to the 2015 effective tax rate.
(9)$2.1 million decrease in other expenses was primarily due to the impacts from the Company's various cost control initiatives implemented during 2016. This was partially offset by a $20.4 million increase in legal settlements and reserves within operating supplies and expenses, which was primarily due to a $22.0 million accrual in 2016 related to unfavorable developments associated with certain litigation within our Swift Refrigerated segment.

$2.3 million pre-tax impairment of certain operations software in 2014.
$6.9 million pre-tax gain on sale in 2013 of three properties classified as held for sale.
$4.9 million in merger and acquisition expense in 2013 for financial advisory, severance and other professional fees related to the Central Acquisition.
$0.9 million in a one-time non-cash equity compensation charge incurred by Central in 2013 for certain stock options that accelerated upon closing of the Central Acquisition.

Results of Operations — Comparison Between the Years Ended December 31, 2015 and 2014
The $36.4 million increase in net income from $161.2 million in 2014 to $197.6 million in 2015, reflects the following:
(1)$246.6 million increase in Revenue xFSR — This was driven by increases in the Truckload, Dedicated, Intermodal, and Non-reportable segments, partially offset by a decrease in Revenue xFSR in the Swift Refrigerated segment.
(2)$316.0 million decrease in fuel surcharge revenue due to declining fuel prices.
(3)$175.1 million decrease in fuel expense, due to declining fuel prices and improved fuel efficiency, partially offset by an increase in total miles driven by company drivers.
(4)$140.9 million decrease in purchased transportation — This was attributed to reduced fuel reimbursements to the owner-operators we contract with and other third parties, as a result of declining fuel prices and a 5.4% decrease in miles driven by the owner-operators we contract with. This was partially offset by increases in owner-operator contracted pay rates, as well as growth in our logistics business.
(5)$141.3 million increase in salaries, wages, and employee benefits, which was primarily due to a 10.3% increase in total miles driven by company drivers, higher company driver wage rates, and an increase in non-driver headcount.
(6)$45.7 million increase in operating supplies and expenses, primarily attributed to higher equipment maintenance costs, which were due to an increase in total miles driven by company drivers, in-servicing new tractors, and processing used tractors for sale. A $5.1 million settlement of a class action lawsuit and related costs was also included here in 2015.
(7)$41.8 million increase in rent and depreciation expense, which was affected by additional depreciation, maintenance, and staging expenses, resulting from a backlog of trucks that were being processed for trade or sale in the latter half of 2015.
(8)$20.3 million increase in insurance and claims expense, primarily due to the first three quarters in 2015, when we had adverse current-year development of certain prior-year claims, higher claims severity trends and higher claims frequency trends.
(9)$41.7 million decrease in interest expense, primarily driven by the call of our Senior Notes in November 2014.
(10)$30.3 million decrease in loss on debt extinguishment — $9.6 million loss on debt extinguishment in 2015 from replacing the 2014 Agreement with the 2015 Agreement, compared to $39.9 million loss on debt extinguishment in 2014 ($34.7 million from redeeming our Senior Notes and $5.2 million from replacing the 2013 Agreement with the 2014 Agreement).
(11)$29.7 million increase in income tax expense driven by an increase in income before income taxes and an increase in the effective tax rate from 35.7% in 2014 to 37.6% in 2015.
(12)$3.4 million increase in other expenses includes a $6.0 million increase in non-operating expenses for a lawsuit that was settled in June 2015, a $1.5 million increase from a pre-tax impairment of a non-operating note receivable in 2015, partially offset by a $2.3 million decrease reflecting an impairment related to certain operations software in 2014.

Non-GAAP Financial Measures
The terms "Adjusted EPS," "Adjusted Operating Ratio," and "Adjusted EBITDA," as we define them, are not presented in accordance with GAAP. These financial measures supplement our GAAP results in evaluating certain aspects of our business. We believe that using these measures improves comparability in analyzing our performance because they remove the impact of items from our operating results that, in our opinion, do not reflect our core operating performance. Management and the Board focus on Adjusted EPS, Adjusted Operating Ratio, and Adjusted EBITDA as key measures of our performance, all of which are reconciled to the most comparable GAAP financial measures and further discussed below. We believe our presentation of these non-GAAP financial measures is useful because it provides investors and securities analysts the same information that we use internally for purposes of assessing our core operating performance and compliance with debt covenants.
Adjusted EPS, Adjusted Operating Ratio, and Adjusted EBITDA are not substitutes for their comparable GAAP financial measures, such as net income, cash flows from operating activities, operating margin, or other measures prescribed by GAAP. There are limitations to using non-GAAP financial measures. Although we believe that they improve comparability in analyzing our period to period performance, they could limit comparability to other companies in our industry if those companies define these measures differently. Because of these limitations, our non-GAAP financial measures should not be considered measures of income generated by our business or discretionary cash available to us to invest in the growth of our business. Management compensates for these limitations by primarily relying on GAAP results and using non-GAAP financial measures on a supplemental basis.
Note: In the GAAP to non-GAAP reconciliations below, 20122013 and 20112012 are included to support the five-year presentation in Part II, Item 6, "Selected Financial Data."
Adjusted EPS — Our definition of the non-GAAP measure, Adjusted EPS, starts with (a) income (loss) before income taxes, the most comparable GAAP measure. We add the following items back to (a) to arrive at (b) adjusted income (loss) before income taxes:
(i)amortization of the intangibles from the 2007 Transactions,
(ii)non-cash impairments,
(iii)other special non-cash items,
(iv)excludable transaction costs,
(v)mark-to-market adjustments on our interest rate swaps, recognized in the income statement, and
(vi)amortization of previous losses recorded in AOCI related to the interest rate swaps we terminated upon our IPO and refinancing transactions in December 2010.2010, and
(vii)severance expense, including cash and equity award impact, related to the departure of certain executive leadership.
We subtract income taxes, at the GAAP effective tax rate as applied to adjusted income before income taxes (except for 20112012 – 2013, when we used the GAAP expected effective tax rate) from (b) to arrive at (c) adjusted earnings. Adjusted EPS is equal to (c) divided by weighted average diluted shares outstanding.
We believe that excluding the impact of derivatives provides for more transparency and comparability since these transactions have historically been volatile. Additionally, we believe that comparability of our performance is improved by excluding impairments that are unrelated to our core operations, as well as intangibles from the 2007 Transactions and other special items that are non-comparable in nature.

2012: $2.3 million lost deposit on fuel technology and related equipment because a supplier ceased operations and $1.1 million for impaired real property.
(2)For 2015, refer to "Non-cash impairments of non-operating assets" discussion under "Results of Operations — Consolidated Operating and Other Expenses," below. In 2012, non-cash impairments of non-operating assets pertained to Swift Power Services, LLC ("SPS"), an entity in which we owned a minority interest and held a secured promissory note. SPS failed to make its first scheduled principal payment to us on the secured promissory note, as well as a quarterly interest payment on December 31, 2012. This was due to a decline in its financial performance resulting from, among other things, a legal dispute with the former owners and its primary customer. This caused us to evaluate the secured promissory note due from SPS for impairment, which resulted in a $6.0 million pre-tax adjustment that was recorded in Impairments"Impairments of non-operating assetsassets" in the fourth quarter of 2012.
(3)For 2013 through2014 and 2015, refer to "Loss on Debt Extinguishment" discussion under "Results of Operations — Consolidated Operating and Other Expenses," below. In 2013, we incurred a $5.5 million loss on debt extinguishment resulting from the repayment in full of certain outstanding Central debt at closing of the Central Acquisition, resulting in a loss on debt extinguishment of $0.5 million, and $5.0 million from the replacement of the 2012 Agreement with the 2013 Agreement. In 2012, we incurred $20.9 million in loss on debt extinguishment from replacing the previous first lien term loan with the 2012 Agreement and $1.3 million from redeeming the remaining fixed rate notes.
(4)In 2013, Central incurred a $0.9 million one-time non-cash equity compensation charge for certain options that accelerated upon the closing of the Central Acquisition.
(5)Excludable transaction costs in 2013 were from the Central Acquisition, in which Swift and Central incurred financial advisory, severance, and other professional fees related to the transaction.
(6)Mark-to-market adjustment of interest rate swaps reflects the portion of the change in fair value of these financial instruments that was recorded in earnings in each period indicated2013 and excludes the portion recorded in AOCI under cash flow hedge accounting.

(7)Amortization of unrealized losses on interest rate swaps reflects the non-cash amortization expense of $5.1 million in 2012 and $15.1 million in 2011, included in derivative interest expense in the consolidated income statements. Non-cash amortization expense iswas comprised of previous losses recorded in AOCI related to the interest rate swaps we terminated upon our IPO and concurrent refinancing transactions in December 2010. Such losses were incurred in prior periods when hedge accounting applied to the swaps and were expensed in relation to the hedged interest payments through the original maturity of the swaps in August 2012.

(8)"Amortization of certain intangibles" specifically reflects the non-cash amortization expense relating to certain intangible assets identified in the 2007 Transactions through which Swift Corporation acquired Swift Transportation Co.
(9)Refer to the discussion "Salaries, Wages, and Employee Benefits" for the year ended December 31, 2016 under "Results of Operations — Consolidated Operating and Other Expenses," below.
(10)Provision for income tax expense at effective rate was based on the following:
2014 and 2015:through 2016: GAAP effective tax rate.
Prior to 2014: GAAP expected effective tax rate:
In 2013, we used a 38.5% rate, as there were variations in the GAAP effective tax rate primarily due to a new tax rate in Mexico, Central's conversion to a C-Corporation from an S-Corporation, fixed asset basis differences and state tax rate changes, Central Acquisition-related costs, as well as the benefit realized from Central's designation as an S-corporation prior to the Central Acquisition.
In 2011 and 2012, we used a 39.0% rate, due to amortization of deferred tax assets related to our pre-IPO interest rate swaps and other items causing fluctuations in the GAAP effective tax rate.
Adjusted Operating Ratio — Our definition of the non-GAAP measure, Adjusted Operating Ratio, starts with (a) operating expense and (b) operating revenue, which are GAAP financial measures. We subtract the following items from (a) to arrive at (c) adjusted operating expense:
(i)    fuel surcharge revenue,
(ii)    amortization of the intangibles from the 2007 Transactions,
(iii)    non-cash operating impairment charges,
(iv)    other special non-cash items, and
(v)    excludable transaction costs.costs, and
(vi)    severance expense, including cash and equity award impact, related to the departure of certain executive leadership.
We then subtract fuel surcharge revenue from (b) to arrive at (d) Revenue xFSR. Adjusted Operating Ratio is equal to (c) adjusted operating expense as a percentage of (d) Revenue xFSR.
We net fuel surcharge revenue against fuel expense in the calculation of our Adjusted Operating Ratio, thereby excluding fuel surcharge revenue from operating revenue in the denominator. Because fuel surcharge revenue is so volatile, we believe excluding it provides for more transparency and comparability. Additionally, we believe that comparability of our performance is improved by excluding impairments, non-comparable intangibles from the 2007 Transactions and other special items.

(4)Refer to the discussion "Salaries, Wages, and Employee Benefits" for the year ended December 31, 2016 under "Results of Operations — Consolidated Operating and Other Expenses," below.
Adjusted EBITDA — Our definition of the non-GAAP measure, Adjusted EBITDA, starts with (a) net income (loss), the most comparable GAAP measure. We add the following items back to (a) to arrive at Adjusted EBITDA:
(i)    depreciation and amortization,
(ii)    interest and derivative interest expense, including fees and charges associated with indebtedness, net of interest income,
(iii)    income taxes,
(iv)    non-cash equity compensation expense,
(v)    non-cash impairments,
(vi)    other special non-cash items, and
(vii)    excludable transaction costs.
We believe that Adjusted EBITDA is a relevant measure for estimating the cash generated by our operations that would be available to cover capital expenditures, taxes, interest, and other investments and that it enhances an investor's understanding of our financial performance. We use Adjusted EBITDA for business planning purposes and in measuring our performance relative to that of our competitors. Our method of computing Adjusted EBITDA is consistent with that used in our debt covenants, specifically our leverage ratio, and is also routinely reviewed by management for that purpose.

In 2012, non-cash impairments of non-operating assets pertained to Swift Power Services, LLC ("SPS"), an entity in which we owned a minority interest and held a secured promissory note. SPS failed to make its first scheduled principal payment to us on the secured promissory note, as well as a quarterly interest payment on December 31, 2012. This was due to a decline in its financial performance resulting from, among other things, a legal dispute with the former owners and its primary customer. This caused us to evaluate the secured promissory note due from SPS for impairment, which resulted in a $6.0 million pre-tax adjustment that was recorded in "Impairments of non-operating assets" in the fourth quarter of 2012.

Our CODMs monitor the GAAP results of our reportable segments, as supplemented by certain non-GAAP information. Refer to "Non-GAAP Financial Measures" above for more details. Additionally, we use a number of primary indicators to monitor our revenue and expense performance and efficiency.
Weekly Trucking Revenue xFSR per Tractor(monitored (monitored monthly)This is our primary measure of productivity for our Truckload, Dedicated, and Swift Refrigerated segments. Weekly Revenue xFSR per tractor is affected by the following factors, which are typically monitored daily:
loaded miles (miles driven when hauling freight);
fleet size (because available loads are spread over available tractors);
rates received for our services; and
network balance (number of loads accepted, compared to available trucks, by market).
We strive to increase our revenue per tractor by improving freight rates with customers, hauling more loads with existing equipment, effectively moving freight and managing balance within our network, maintaining our tractors, and recruiting and retaining company drivers, and attracting and maintaining contracts with owner-operators.

Deadhead Miles Percentage (monitored daily) — This is calculated by dividing the number of unpaid miles by the total number of miles driven. We monitor deadhead miles percentage in Truckload and Swift Refrigerated, as we strive to reduce our number of deadhead miles within these segments. By balancing our freight flows and planning consecutive loads with shorter distances between the drop-off and pick-up locations, we are able to reduce the percentage of deadhead miles driven to allow for more revenue-generating miles during our drivers’drivers' hours-of-service. This also enables us to reduce wage, fuel, and other costs associated with deadhead miles.
Average Operational Truck Count(monitored (monitored daily) — We use this measure for all of our reportable segments. It includes tractors driven by company drivers as well as owner-operator units. This measure changes based on our ability to adjust our fleet size in response to changes in demand.
Load Count and Average Container Count(monitored (monitored daily) — Within Intermodal, we monitor load count and average container count. These metrics allow us to measure our utilization of our container fleet.
Adjusted Operating Ratio(monitored (monitored monthly) — We consider this ratio an important measure of our operating profitability for each of our reportable segments. We define and reconcile Adjusted Operating Ratio under "Non-GAAP Financial Measures," above. GAAP Operating Ratio is operating expenses as a percentage of revenue, or the inverse of operating margin, and produces an indication of operating efficiency. It is widely used in our industry as an assessment of management’smanagement's effectiveness in controlling all categories of operating expenses.
The following tables are GAAP to non-GAAP reconciliations for each reportable segment's Adjusted Operating Ratio:

Truckload Revenue —The decrease in operating revenue for 2016, as compared to 2015, consisted of an $80.5 million decrease in fuel surcharge revenue, due to lower fuel prices (on average), and a $75.6 million decrease in Revenue xFSR. The 3.9% decrease in Revenue xFSR reflects the following:
2.6% decrease in total loaded miles, and a
1.3% decrease in Revenue xFSR per loaded mile.
The 2.9% decrease in weekly Revenue xFSR per tractor reflects the following:
1.6% decrease in loaded miles per tractor per week, and the
1.3% decrease in Revenue xFSR per loaded mile, noted above.
Truckload volumes and pricing continued to be challenged with excess industry capacity, excess customer inventories, and depressed shipping demand during 2016. We continued our participation in the spot market during the year to help offset the lack of available freight in certain markets. This helped to balance our network, but had a negative impact on Revenue xFSR per loaded mile. We continue to monitor our spot market activity and expect to reduce our participation.
Truckload Operating Income — Operating income decreased for 2016, as compared to 2015, which was primarily driven by the decrease in Revenue xFSR, discussed above. Other factors that affected operating income are discussed within "Truckload Adjusted Operating Ratio," below.
Truckload Adjusted Operating Ratio — Adjusted Operating Ratio increased 350 basis points for 2016, as compared to 2015. This was primarily driven by the decrease in Revenue xFSR, discussed above. In addition to the industry challenges associated with volumes and pricing that negatively affected Revenue xFSR, the continued soft used truck market contributed to an increase in depreciation expense (due to a change in projected residual values of certain trucks) and a decrease in gain on disposals of property and equipment. Additionally, driver salaries and wages expense increased, primarily due to the company driver wage increase implemented in May 2015.
Throughout 2016, we continued to implement various measures to improve cost control and efficiency, including right-sizing the fleet to drive improvements in asset utilization, improving freight and equipment network balance, continuing to focus on driver safety and satisfaction, and other cost control initiatives to partially offset the negative impacts from the items noted above.

Dedicated Revenue — The increase in operating revenue for 2016, as compared to 2015, included a $28.1 million decrease in fuel surcharge revenue, due to lower fuel prices, more than offset by a $71.6 million increase in Revenue xFSR. The 8.4% increase in Revenue xFSR includes the following:
7.7% increase in weekly Revenue xFSR per tractor from improved pricing and freight mix, and a
0.4% increase in average operational truck count.
The Dedicated segment's leadership team has sustained its performance in delivering improvements in fleet efficiency, pricing, and underperforming accounts which contributed to the increase in weekly Revenue xFSR per tractor.
Dedicated Operating Income —Operating income increased for 2016, as compared to 2015, which was primarily driven by the increase in Revenue xFSR, discussed above. Other factors that affected operating income are discussed within "Dedicated Adjusted Operating Ratio," below.
Dedicated Adjusted Operating Ratio — Adjusted Operating Ratio decreased 200 basis points for 2016, as compared to 2015. This was primarily driven by the increase in Revenue xFSR, discussed above, as well as the segment's continued focus on improving cost control. These improvements were partially offset by an increase in driver salaries, wages, and employee benefits, primarily due to the company driver wage increases implemented in 2015 and an increase in group health insurance expense. Additionally, rent and depreciation expenses were higher, and gains on disposals of property and equipment were lower due to the soft used truck market.

Swift Refrigerated Revenue — The decrease in operating revenue for 2016, as compared to 2015, consisted of a $14.2 million decrease in fuel surcharge revenue, due to lower fuel prices, and a $24.8 million decrease in Revenue xFSR. The 7.6% decrease in Revenue xFSR reflects the following:
3.6% decrease in Revenue xFSR per loaded mile, and a
4.0% decrease in total loaded miles.
The refrigerated market remained challenging as shippers continued to take advantage of the spot market, leading to sustained pricing pressures. This, along with the cost structure inherent in operating a refrigerated business, unfavorably impacted the profitability of this segment. In response to these market challenges, Swift Refrigerated continued to work on securing quality freight, improving asset utilization, and controlling costs. These efforts contributed to an increase in weekly Revenue xFSR per tractor of 2.9%, which was favorably impacted by a 6.8% increase in loaded miles per tractor per week and unfavorably impacted by the decrease in Revenue xFSR per loaded mile, noted above. During 2016, we continued refining our refrigerated network, allowing more efficient matching of trucks with freight. As a result, deadhead percentage in this segment improved.
Swift Refrigerated Operating (Loss) Income —Swift Refrigerated recognized an operating loss for 2016, as compared to operating income for 2015. The unfavorable change was driven by the decrease in Revenue xFSR, discussed above, and the factors discussed within "Swift Refrigerated Adjusted Operating Ratio," below.
Swift Refrigerated Adjusted Operating Ratio — Adjusted Operating Ratio significantly increased from 2015, as compared to 2016, This was primarily driven by the decrease in Revenue xFSR, discussed above, as well as a $22.0 million increase in legal reserves related to unfavorable developments associated with certain litigation within this segment. This was partially offset by decreases in rent expense, salaries and wages, and other operating expenses from our initiatives to improve cost control.

Intermodal Revenue — The decrease in operating revenue for 2016, as compared to 2015, consisted of a $16.0 million decrease in fuel surcharge revenue, due to lower fuel prices, and a $14.4 million decrease in Revenue xFSR. The 4.2% decrease in Revenue xFSR reflects the following:
5.1% decrease in load count, partially offset by a
0.9% increase in Revenue xFSR per load.
Securing intermodal freight that met our internal pricing requirements continued to be a challenge in 2016, as United States rail traffic was lower overall in 2016, as compared to 2015. There were container and freight imbalances and increased pricing pressures, as an increasing number of intermodal providers continued with their attempts to balance their networks and gain volume through aggressive pricing. COFC loads decreased by 2.5%, while TOFC loads were progressively ramped down, as we strategically focused on our COFC service. In March 2016, the TOFC service offering was completely eliminated, which we believe allows for increased operational efficiencies.
Intermodal Operating (Loss) Income —Intermodal incurred an operating loss of $0.5 million during 2016, as compared to operating income of $4.1 million for 2015. This was primarily driven by the factors discussed within "Intermodal Revenue," above, and "Intermodal Adjusted Operating Ratio," below.
Intermodal Adjusted Operating Ratio — Adjusted Operating Ratio increased 140 basis points for 2016, as compared to 2015. This was primarily driven by the decrease in Revenue xFSR, discussed above, partially offset by the favorable impacts from our initiatives to improve our cost infrastructure and operational efficiencies.

Truckload Revenue — Although operatingOperating revenue decreased in 2015, compared to 2014. Compared to 2014, Revenue xFSR increased by 4.7% from 2014 to 2015. The following factors contributed to the increase in Revenue xFSR:2015, impacted by:
4.0% increase in Revenue xFSR per loaded mile, primarily driven by pricing increases and freight mix.
0.7% increase in total loaded miles.
The following factors impacted the 2.8% increase in weekly Revenue xFSR per tractor:
4.0% increase in Revenue xFSR per loaded mile.
partially offset by a 1.2% decrease in loaded miles per tractor per week from disruption associated with trading and in-servicing more tractors in 2015, compared to 2014. This was the result of our acceleration of the average trade-in cycle for our tractors.
Truckload Operating Income —Operating income decreased slightly from 2014 to 2015. This resulted in awas primarily driven by the factors discussed within "Truckload Revenue," above, and "Truckload Adjusted Operating Ratio," below.
Truckload Adjusted Operating Ratio — Adjusted Operating Ratio increased 70 basis point increase in Adjusted Operating Ratio,points for 2015, as compared to 2014. This was primarily caused by the increases in wages for our company drivers and contracted pay rates for owner-operators, discussed above, as well as adverse development of prior-year insurance claims and corresponding increase in reserves. This was partially offset by increases in customer pricing, as well as reduced fuel expense associated with declining fuel prices and better fuel efficiency.

a 5.9% increase in weekly Revenue xFSR per tractor, which was driven by a 4.6% increase in Revenue xFSR per loaded mile (from contractual rate increases, freight mix and an increase in paid repositioning) and a 1.2% improvement in loaded miles per truck per week in 2014;
offset by a 4.6% decrease in average tractors available for dispatch, as equipment was shifted from our Truckload segment to facilitate the growth within our Dedicated segment. As a result of this shift of resources and severe weather during the first quarter of 2014, total loaded miles decreased by 3.4%.
Truckload Operating Income —Operating income increased in 2014, compared to 2013. The increase in operating income contributed to an improvement in Adjusted Operating Ratio of 160 basis points in 2014, compared to 2013. The improvement in Adjusted Operating Ratio was primarily due to improvements in pricing, productivity and fuel expense, partially offset by increased costs of driver wages, insurance claims, workers' compensation, winter weather-related items and equipment. Improvements in fuel expense reflect a combination of declining diesel prices and better fuel efficiency.

Dedicated RevenueOperating revenue increased in 2014, compared to 2013. Revenue xFSR increased 23.3% over 2013. The addition of new customer accounts in the latter half of 2013 and throughout 2014 contributed to a 29.3% increase in average tractors available for dispatch. Revenue xFSR per tractor decreased due to the varying operational requirements of the new customer contracts.
Dedicated Operating Income — Operating income decreased in 2014, compared to 2013. The decrease in operating income resulted in an unfavorable change in Adjusted Operating Ratio of 370 basis points in 2014, compared to 2013. This deterioration in Dedicated Adjusted Operating Ratio was primarily due to higher driver wages, as well as increased costs associated with insurance and claims, starting up new customer accounts, and the severe winter weather experienced in the first quarter of 2014. This was partially offset by a favorable impact in fuel expense from declining fuel prices.

Swift Refrigerated Revenue —Operating revenue decreased in 2014, compared to 2013. Compared to 2013, Revenue xFSR decreased in 2014 by 6.4% impacted by:
a decrease in total loaded miles of 13.9%, which was the result of a 5.7% decrease in average tractors available for dispatch, severe winter weather in the first quarter of 2014, Central's conversion to Swift's system and process in February 2014, and challenges faced in the driver market.
a decrease in weekly Revenue xFSR per tractor of 0.4% primarily from freight mix changes. The decrease in weekly Revenue xFSR per tractor reflects a decrease in loaded miles per tractor of 8.7%, offset by an increase in Revenue xFSR per loaded mile of 8.7%. Swift Refrigerated added several new dedicated locations which operated with a lower average length of haul, higher deadhead and a higher Revenue xFSR per loaded mile.
Swift Refrigerated Operating Income —Operating income decreased in 2014, compared to 2013. The decrease in operating income resulted in an unfavorable change in Adjusted Operating Ratio of 70 basis points from 2013 to 2014. The deterioration in Adjusted Operating Ratio was primarily related to the severe weather experienced in the first quarter of 2014, higher equipment costs, higher deadhead percentage, higher driver wages, the challenges associated with Central's conversion to Swift's system in February 2014 and the driver market, as well as the continued challenges with the large unique dedicated customer added in June 2013. This was partially offset by the increase in Revenue xFSR per loaded mile of 8.7% in 2014, compared to 2013.

a 1.0% increase in Revenue xFSR per load. The number of COFC loads increased in 2014, while TOFC loads decreased, as we continued to shift our focus to more profitable freight.
Intermodal Operating Income —Operating income increased in 2014, compared to 2013. The increase in operating income resulted in a favorable change in Adjusted Operating Ratio of 70 basis points from 2013 to 2014. The improved Adjusted Operating Ratio was primarily due to improvements in our network, utilization of our equipment and an increase in Revenue xFSR per load.

Results of Operations — Consolidated Operating and Other Expenses
Operating Expenses — The following tables present certain operating expenses from our consolidated income statements, including each operating expense as a percentage of operating revenue and as a percentage of Revenue xFSR. Fuel surcharge revenue can be volatile and is primarily dependent upon the cost of fuel, rather than operation expenses unrelated to fuel. Therefore, we believe that Revenue xFSR is a better measure for analyzing many of our expenses and operating metrics.

Salaries, wages, and employee benefits are primarily affected by the total number of miles driven by company drivers, the rate per mile we pay our company drivers, and employee benefits, including health care, workers’workers' compensation, and other benefits. ToTypically to a lesser extent, non-driver employee headcount, compensation, and benefits affect the expense.
The increase in salaries, wages, and employee benefits was primarily due to a 10.3%the driver wage increase implemented in May 2015 and an increase in total milesgroup health insurance expenses. Miles driven by company drivers higher company driver wage rates discussed above, an increase in non-driver headcount, and an increase in workers' compensation expensewere relatively flat from adverse development of prior-year claims and corresponding increase in reserves.2015 to 2016. The compensation paid to our company drivers and other employees may increase further in future periods as the economy strengthens and other employment alternatives become more available.
Additionally, salaries, wages, and employee benefits increased due to Jerry Moyes' retirement package. In conjunction with the Company's September 8, 2016 announcement that Mr. Moyes would retire from his position as Chief Executive Officer effective December 31, 2016, the Company entered into an agreement with Mr. Moyes to memorialize the terms of his retirement. The Company contracted with Mr. Moyes to serve as a non-employee consultant from January 1, 2017 through December 31, 2019, during which time the Company will pay Mr. Moyes a monthly consulting fee of $0.2 million in cash. Additionally, the Company modified the vesting terms and forfeiture conditions of Mr. Moyes' previously-granted equity awards. As a result of the terms of the agreement, the Company incurred a one-time expense in September 2016 of $7.1 million, consisting of $6.8 million in accrued consulting fees and $0.3 million for the impact of the equity award modifications. The amount is included in the non-reportable segments' income statement.

Operating supplies and expenses primarily consist of ordinary vehicle repairs and maintenance, costs associated with preparing tractors and trailers for sale or trade-in, driver expenses, driver recruiting costs, legal and professional services fees, general and administrative expenses, and other costs. Operating supplies and expenses are primarily affected by the age of our company-owned fleet of tractors and trailers, the number of miles driven in a period, driver turnover, and typically to a lesser extent by efficiency measures in our repair and maintenance shops.
The increase in operating supplies and expenses was primarily attributed to higher equipment maintenance costs,affected by a $20.4 million increase in legal settlements and reserves, which werewas primarily due to the increasea $22.0 million accrual in total miles driven by company drivers noted above, in-servicing new tractors,2016 related to unfavorable developments associated with certain litigation within our Swift Refrigerated segment.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS — CONTINUED


We believe the most effective protections against fuel cost increases are maintaining a fuel-efficient fleet by incorporating fuel efficiency measures into our business, such as aerodynamic equipment, slower tractor speeds, engine idle limitations, and a reduction of deadhead miles; actively managing fuel procurement; and maintaining an effective fuel surcharge program. To mitigate unrecovered fuel exposure, we have worked to negotiate more robust surcharge programs with customers identified as having inadequate programs. We generally have not used derivatives to hedge against higher fuel costs in the past, but continue to evaluate this possibility. To mitigate the impact of rising fuel costs, we have contracted to purchase some fuel from certain fuel suppliers at a fixed price or within banded pricing for a specific period, usually not exceeding twelve months.
The decrease in our fuel expense was the result of lower fuel prices and slightly improved fuel efficiency. During 2016, the average DOE index was $2.30, compared to 2015, which had an average DOE index of $2.71. As noted above, miles driven by company drivers were relatively flat from 2015 to 2016.

Purchased transportation expense includes payments made to owner-operators, rail partners, and other third parties for their services. The decrease in the expense was attributed to reduced fuel reimbursements to owner-operators, as a result of lower fuel prices and a 2.9% decrease in miles driven by owner-operators. Additionally, lower intermodal freight volumes resulted in a decrease in payments to rail carriers, further contributing to the decrease in the expense. This was partially offset by the impact of increasing owner-operator contracted pay rates in May 2015.
Pay rates for the owner-operators we contract with may increase further in future periods as the economy strengthens and other employment alternatives become more available.

Insurance and claims expense consists of insurance premiums and estimated payments and expenses for claims for bodily injury, property damage, cargo damage, and other casualty events, as well as owner-operator policies through our captive insurance subsidiary. The primary factors affecting our insurance and claims are the number of miles driven by our drivers and owner-operators, the frequency and severity of accidents, trends in the development factors used in our actuarial accruals, and developments in large, prior-year claims. Furthermore, our self-insured retention of $10.0 million per occurrence for accident claims can cause volatility in this expense.
The increase in insurance and claims was primarily due to an increase in collision expense related to company equipment, as well as negative developments within both prior year and current year claims associated with the owner-operator policies provided under our captive insurance company. Additionally, despite our total crashes per million miles decreasing 4.9% from 2015 to 2016, our insurance and claims expense for bodily injury and property damage increased slightly as a result of our average cost per claim reserve increasing, due to negative development of prior and current year claims.

Rental expense consists primarily of payments for tractors and trailers financed with operating leases. Depreciation and amortization of property and equipment consists primarily of depreciation for owned tractors and trailers and amortization of those financed with capital leases. The primary factors affecting these expense items are the size and age of our revenue equipment fleet, the cost of new equipment, and the relative percentage of owned versus leased equipment. We believe it is appropriate to combine our rental expense with our depreciation and amortization of property and equipment for analytical purposes because the mix of our leased versus owned tractors varies from period to period.
Combined rental expense and depreciation and amortization of property and equipment slightly increased overall and as a percentage of Revenue xFSR (primarily due to an increase in depreciation resulting from a reduction in the residual values of certain tractors). This was partially offset by a decrease in tractor and trailer units from 2015 to 2016.

In conjunction with the 2007 Transactions, definite-lived intangible assets with a gross carrying value of $261.2 million were recorded. The related amortization comprised $15.6 million of total amortization expense in both 2016 and 2015. Amortization of intangibles also included $1.2 million each year related to intangible assets existing prior to the 2007 Transactions.
We anticipate that the composition and amount of amortization associated with intangible assets as of December 31, 2016 will remain at $16.8 million in 2017, and will decrease to $16.3 million in 2018, of which $0.7 million will represent the final amortization of the intangible assets existing prior to the 2007 Transactions. Amortization of intangible assets is expected to be $15.6 million from 2019 through 2021. Actual amounts of amortization expense may differ from estimated amounts due to additional intangible asset acquisitions, impairment of intangible assets, accelerated amortization of intangible assets, and other events.

Gain on disposal of property and equipment is dependent upon the number of tractors and trailers that we have available for trade or sale during the period, execution of those sales, the type of equipment we are selling, and the used equipment market, among other things. The decrease in gain on disposal of property and equipment was primarily driven by lower gain on disposals of tractors, due to a soft used truck market in 2016, compared to 2015. This was partially offset by an increase in volume of trailers sold.

Interest ExpenseInterest expense is comprised of debt interest expense, as well as amortization of DLCs, and (with respect to 2015) OID. The decrease in interest expense was driven by overall lower debt balances, as well as more favorable interest rates and terms in the 2015 Agreement, which replaced the 2014 Agreement in July 2015.
Derivative Interest ExpenseDerivative interest expense reflects losses reclassified from AOCI into net income from the effective portion of cash flow hedges, as well as the income effect of mark-to-market adjustments and current settlements of interest rate swaps, which were de-designated in February 2013. The final settlement of our interest rate swaps occurred in July 2015.
Loss on Debt ExtinguishmentIn July 2015, we replaced the 2014 Agreement with the 2015 Agreement, which resulted in a loss on debt extinguishment of $9.6 million, reflecting the write-off of the unamortized OID and DLCs related to the 2014 Agreement.
Non-cash Impairments of Non-operating AssetsIn September 2013, the Company agreed to advance up to $2.3 million, pursuant to an unsecured promissory note, to an independent fleet contractor that transported freight on Swift's behalf. In March 2015, management became aware that the independent contractor violated various covenants outlined in the unsecured promissory note, which created an event of default that made the principal and accrued interest immediately due and payable. As a result of this event of default, as well as an overall decline in the independent contractor's financial condition, management re-evaluated the fair value of the unsecured promissory note. At March 31, 2015, management determined that the remaining balance due from the independent contractor to the Company was not collectible, which resulted in a $1.5 million pre-tax adjustment that was recorded in "Non-cash impairments of non-operating assets" in the Company's consolidated income statements.
Legal Settlements and Reserves In June 2016, we reserved $3.0 million for expected costs associated with a certain legal matter.
In June 2015, the Company settled a lawsuit relating to a contractual dispute with a company in the business of supplying ancillary fuel system equipment.  As a result of this settlement, we incurred a $6.0 million expense.
Income Tax ExpenseThe effective tax rate in 2016 was 30.6%, which was lower than our expectation of 36.5%. The difference reflects reduced taxes primarily due to a reduction of income before income taxes. Additionally, federal domestic production activities deductions, certain income tax credits received by our foreign and domestic subsidiaries, and a reduction in our uncertain tax position reserve contributed to the difference. We expect the 2017 effective tax rate to be in the range of 36.0% to 37.0%.
The effective tax rate in 2015 was 37.6%, which was lower than our expectation of 38.5%, primarily due to federal employment income tax credits realized in the fourth quarter of 2015 from tax legislation then-enacted, as well as the benefit of prior year federal employment income tax credits realized in the third quarter of 2015.
Note 11 to the consolidated financial statements provides additional analysis related to income taxes.

A $5.1 million settlement of a class action lawsuit and related costs in 2015, as well as an increase in toll costs, compared to 2014, were also included in operating supplies and expenses.

The decrease in thepurchased transportation expense was attributed to reduced fuel reimbursements to the owner-operators we contract with and other third parties, as a result of declining fuel prices and a 5.4% decrease in miles driven by the owner-operators we contract with. This was partially offset by the increases in owner-operator contracted pay rates noted above, as well as growth in our logistics business.
Contracted pay rates for the owner-operators we contract with may increase further in future periods as the economy strengthens and other employment alternatives become more available.

Insurance and claims expense consists of insurance premiums and estimated payments and expenses for claims for bodily injury, property damage, cargo damage, and other casualty events. The primary factors affecting our insurance and claims are the number of miles driven by our drivers and owner-operators, the frequency and severity of accidents, trends in the development factors used in our actuarial accruals, and developments in large, prior-year claims. Furthermore, our self-insured retention of $10.0 million per occurrence for accident claims can cause volatility in this expense.
The increase in insurance and claims was primarily due to the first three quarters in 2015, when we had adverse current-year development of certain prior-year claims, higher claims severity trends, and higher claims frequency trends. However, our crash frequency and severity trends improved in the fourth quarter of 2015, partially driven by our investments in new equipment with enhanced safety features, as well as improved driver retention and other safety initiatives.

Rental expense consists primarily of payments for tractors and trailers financed with operating leases. Depreciation and amortization of property and equipment consists primarily of depreciation for owned tractors and trailers or amortization of those financed with capital leases. The primary factors affecting these expense items are the size and age of our revenue equipment fleet, the cost of new equipment, and the relative percentage of owned versus leased equipment. We believe it is appropriate to combine our rental expense with our depreciation and amortization of property and equipment for analytical purposes because the mix of our leased versus owned tractors varies from period to period.

The increase in the combined expense was primarily due to growth in tractors and trailers in our fleet from December 31, 2014 to December 31, 2015. See consolidated table of revenue equipment within "Executive Summary," above. Higher revenue equipment replacement costs additionally contributed to the increase in the expense. As a percentage of Revenue xFSR, rental expense and depreciation and amortization of property and equipment remained relatively consistent from 2014 to 2015.

In conjunction with the 2007 Transactions, definite-lived intangible assets with a gross carrying value of $261.2 million were recorded. The related amortization comprised $15.6 million of total amortization expense in both 2015 and 2014. Amortization of intangibles also included $1.2 million each year related to intangible assets existing prior to the 2007 Transactions.
We anticipate that the composition and amount of amortization associated with intangible assets as of December 31, 2015 will remain consistent at $16.8 million through 2017, and will decrease to $16.3 million in 2018, of which $0.7 million will represent the final amortization of the intangible assets existing prior to the 2007 Transactions. Amortization of intangible assets is expected to be $15.6 million in both 2019 and 2020. Actual amounts of amortization expense may differ from estimated amounts due to additional intangible asset acquisitions, impairment of intangible assets, accelerated amortization of intangible assets and other events.

In the third quarter of 2014, we recognized gains on the sale of two redundant facilities associated with the Central Acquisition, resulting in a gain of $3.0 million.

Interest Expense Interest expense is comprised of debt interest expense, as well as amortization of deferred financing costs and OID. The decrease in interest expense in 2015 was primarily driven by our call of the Senior Notes in November 2014. Also contributing to the decrease in interest expense was the impact of replacing the 2014 Agreement with the 2015 Agreement, which had lower interest rates.
Derivative Interest ExpenseDerivative interest expense reflects losses reclassified from AOCI into net income from the effective portion of cash flow hedges, as well as the income effect of mark-to-market adjustments and current settlements of interest rate swaps, which were de-designated in February 2013. The final settlement of our interest rate swaps occurred in July 2015. As such, there was no derivative interest expense thereafter, causing the decrease in the expense from 2014 to 2015.
Loss on Debt Extinguishment In July 2015, we replaced the 2014 Agreement with the 2015 Agreement, which resulted in a loss on debt extinguishment of $9.6 million, reflecting the write-off of the unamortized OID and deferred financing fees related to the 2014 Agreement.
In November 2014, the Company redeemed, in full, the remaining $428.1 million face value of its Senior Notes. The Company paid 105% of face value, plus accrued and unpaid interest, to call the Senior Notes. The November 2014 redemption followed a series of refinancing transactions that occurred in the first nine months of 2014, in which the Company used cash on hand to repurchase $71.9 million in principal of the Senior Notes at an average price of 109.05%. In total, these transactions resulted in a loss on debt extinguishment of $34.7 million, reflecting the write-off of the unamortized OID.
Also, in June 2014, we replaced the 2013 Agreement with the 2014 Agreement, which resulted in a loss on debt extinguishment of $5.2 million, reflecting the write-off of the unamortized OID and deferred financing fees related to the 2013 Agreement and the previous revolving credit line.
Non-cash Impairments of Non-operating Assets In September 2013, the Company agreed to advance up to $2.3 million, pursuant to an unsecured promissory note, to an independent fleet contractor that transported freight on Swift's behalf. In March 2015, management became aware that the independent contractor violated various covenants outlined in the unsecured promissory note, which created an event of default that made the principal and accrued interest immediately due and payable. As a result of this event of default, as well as an overall decline in the independent contractor's financial condition, management re-evaluated the fair value of the unsecured promissory note. At March 31, 2015, management determined that the remaining balance due from the independent contractor to the Company was not collectible, which resulted in a $1.5 million pre-tax adjustment that was recorded in "Non-cash impairments of non-operating assets" in the Company's consolidated income statements.

Legal SettlementSettlements and Reserves In June 2015, the Company settled a lawsuit relating to a contractual dispute with a company in the business of supplying ancillary fuel system equipment.  As a result of this settlement, we incurred a $6.0 million expense.
Income Tax Expense The effective tax rate in 2015 was 37.6%, which was lower than our expectation of 38.5%, primarily due to federal employment income tax credits realized in the fourth quarter of 2015 from tax legislation recently enacted, as well as the benefit of prior year federal employment income tax credits realized in the third quarter of 2015.
The effective tax rate in 2014 was 35.7%, which was lower than our expectation of 38.5%, primarily due to the benefit of prior year federal income tax credits realized in the third quarter of 2014 and federal employment income tax credits realized in the fourth quarter of 2014.

Interest Expense The decrease in interest expense was primarily due to redeeming our Senior Notes in November 2014, lowering our other debt balances primarily from voluntary prepayments, and replacing the 2013 Agreement with the 2014 Agreement, which had lower interest rates.
Derivative Interest ExpenseDerivative interest expense reflects losses reclassified from AOCI into net income from the effective portion of cash flow hedges, as well as the income effect of mark-to-market adjustments and current settlements of interest rate swaps, which were de-designated in February 2013.
Merger and Acquisition Expense — As the result of the Central Acquisition, both Swift and Central incurred certain transactional related expenses, including financial advisory, severance and other professional fees in 2013.
Loss on Debt ExtinguishmentIn November 2014, the Company redeemed, in full, the remaining $428.1 million face value of its Senior Notes. The Company paid 105% of face value, plus accrued and unpaid interest, to call the Senior Notes. The November 2014 redemption followed a series of refinancing transactions that occurred in the first nine months of 2014, in which the Company used cash on hand to repurchase $71.9 million in principal of the Senior Notes at an average price of 109.05%. In total, these transactions resulted in a loss on debt extinguishment of $34.7 million, reflecting the write-off of the unamortized OID.
Also, in June 2014, we replaced the 2013 Agreement with the 2014 Agreement, which resulted in a loss on debt extinguishment of $5.2 million, reflecting the write-off of the unamortized OID and deferred financing fees related to the 2013 Agreement and the previous revolving credit line.
In 2013, $5.0 million of the loss on debt extinguishment was from replacing the 2012 Agreement with the 2013 Agreement and $0.5 million was from repaying certain outstanding Central debt in full at closing of the Central Acquisition.
Gain on Sale of Real PropertyGains and losses from sales of properties that are unrelated to our core operations are included in this line item. During 2013, we disposed of two non-operating properties in Phoenix, Arizona and one non-operating property in Wilmington, California, resulting in a gain of $6.9 million. We did not sell any non-operating facilities in 2014.
Income Tax ExpenseThe effective tax rate in 2014 was 35.7%, which was lower than our expectation of 38.5%, primarily due to the benefit of prior year federal income tax credits realized in the third quarter of 2014 and federal employment income tax credits realized in the fourth quarter of 2014.
The effective tax rate for 2013 was 39.4%, which was 90 basis points higher than our normalized effective tax rate. This increase was primarily due to a new tax rate in Mexico, Central's conversion to a C-Corporation from an S-Corporation, fixed asset basis differences and state tax rate changes, Central Acquisition-related costs, as well as the benefit realized from Central's designation as an S-corporation prior to the Central Acquisition.

(3)Restricted cash and cash equivalents, and restricted short-term investments are primarily held by our captive insurance companies for claims payments.
Uses of Liquidity
Our business requires substantial amounts of cash for operating expenses, capital expenditures, other assets, working capital changes, principalactivities, including salaries and interestwages paid to our employees, contract payments on our obligations,to owner-operators, insurance and claims payments, tax payments, and lettersothers. We also use large amounts of cash and credit required for insurance.the following activities:
Capital ExpendituresWhen justified by customer demand, as well as our liquidity and our ability to generate acceptable returns, we make substantial cash capital expenditures to maintain a modern company tractor fleet, refresh our trailer fleet, and fund growth in our revenue equipment fleet. We expect the net cash capital expenditures required to maintain our current fleet to be in the range of approximately $200$250.0 million to $250$300.0 million for 2016. Further,annually, but intend to keep this range as flexible as possible to appropriately respond to pending business opportunities and the overall market environment. In addition to this, we expect to continue to obtain a portion of our equipment under operating and capital leases, which are not reflected as net cash capital expenditures. In addition, weleases. We believe we have ample flexibility with our trade cycle and purchase agreements to alter our current plans if economic or other conditions warrant. Beyond 2016, we expect our net capital expenditures to remain substantial.
We believe we can finance our expected cash needs, including debt repayment, for at least the next twelve months with cash flows from operations, borrowings under our revolving credit facility, borrowings under our 2015 RSA, and lease financing. Over the long-term, we will continue to have significant capital requirements, which may require us to seek additional borrowings,borrowing, lease financing, or equity capital. The availability of financing or equity capital will depend upon our financial condition and results of operations as well as prevailing market conditions. If such additional borrowings,borrowing, lease financing, or equity capital is not available at the time we need to incur such indebtedness,it, then we may be requiredneed to utilizeborrow more under the revolving portion of our senior secured credit facility (if not then fully drawn), extend the maturity of then-outstanding indebtedness,debt, rely on alternative financing arrangements, or engage in asset sales.
There can be no assurance that we will be able to incur additional debt under our existing financial arrangements to satisfy our ongoing capital requirements. However, we believe the combination of our expected cash flows, financing available through operating leases, which are not subject to debt incurrence baskets, the capital lease basket, available funds under the 2015 RSA, and availability under our revolving credit facilitythe New Revolver will be sufficient to fund our expected capital expenditures for 2016.at least the next twelve months.
Material Debt Agreements
Principal and Interest PaymentsAs of December 31, 2015,2016, we had $1.4 billion in material debt and capital lease obligations at the following carrying values:
$669.8 million: Newof $1.1 billion, which are discussed under "Material Debt Agreements," below. A significant amount of our cash flows from operations are committed to minimum payments of principal and interest on our debt facilities and lease obligations.

Share Repurchases — From time to time, and depending on free cash flow availability, debt levels, stock prices, general economic and market conditions, as well as Board approval, we may repurchase shares of our outstanding common stock. In September 2015, the Board authorized the Company to repurchase up to $100.0 million of its outstanding Class A common stock. We finished our repurchases under this authorization in January 2016. In February 2016, the Board authorized an additional $150.0 million in share repurchases, of which $62.9 million remained available as of December 31, 2016.

________
(1)Represents borrowings owed at December 31, 2016. Interest rates vary.
(2)
Represents principal payments owed at December 31, 2016. The borrowing consists of capital leases with finance companies, fixed borrowing amounts, and fixed interest rates, as set forth on each applicable lease schedule. Accordingly, interest on each lease varies between schedules. The Company's capital leases are typically structured with balloon payments at the end of the lease term equal to the residual value the Company is contracted to receive from certain equipment manufacturers upon sale or trade back to the manufacturers.
(3)Represents interest obligations on long-term debt, the 2015 RSA, and capital lease obligations. For variable rate debt, the interest rate in effect as of December 31, 2016 was utilized. The table assumes long-term debt and the 2015 RSA are held to maturity.
(4)Represents future monthly rental payment obligations, which include an interest element, under operating leases for tractors, trailers, chassis, and facilities. Substantially all lease agreements for revenue equipment have fixed payment terms based on the passage of time. We lease 8,086 tractors under operating leases, which includes 5,234 company tractors and 2,852 owner-operator tractors financed by the Company. The tractor lease agreements generally stipulate maximum miles and provide for mileage penalties for excess miles. These leases generally run for a period of three to five years for tractors and five to seven years for trailers.
(5)Represents purchase obligations for revenue equipment, facilities, and non-revenue equipment, of which a significant portion is expected to be financed with operating and capital leases to the extent available. We have the option to cancel tractor purchase orders with 60 to 90 days' notice. As of December 31, 2016, approximately 28.6% of this amount had become non-cancelable.
(6)Deferred taxes and long-term portion of claims accruals are excluded from other long-term liabilities in the above table.

Favorable Cash Flow Variances:
(6)$103.2 million decrease in capital expenditures from 2015 to 2016, due to the timing of lease financing versus cash capital expenditures. Our primary focus in 2016 has been fleet utilization. As such, we did not add net capacity within our truck count during 2016; however, we did replace older revenue equipment with new equipment during this time. These replacements were primarily funded using operating leases, as compared to 2015, when our revenue equipment additions were funded using a mixture of operating leases, capital leases, and cash on hand.
(7)$7.8 million favorable change in restricted cash and cash equivalents. Changes in the balance are driven by the amount and timing of future claims payments by our captive insurance companies.

Cash Flow Impact of the 2014 Agreement: In June 2014, we entered into the 2014 Agreement, replacing the 2013 Agreement. Total proceeds received under the 2014 Agreement included $50.0 million at closing under the $500.0 million delayed-draw Old Term Loan A and $400.0 million under the Term Loan B. Additionally, we borrowed $164.0 million under the Old Revolver of the 2014 Agreement. With these proceeds, we repaid the then-existing first lien term loan B-1 tranche and first lien term loan B-2 tranche under the 2013 Agreement with outstanding principal balances of $229.0 million and $370.9 million plus accrued interest, respectively, and paid $10.5 million in deferred financing fees at closing.

Off Balance Sheet ArrangementsFavorable Cash Flow Variances:
We lease 8,715 tractors under operating leases, which includes 5,599 company tractors and 3,116 owners-operator tractors financed by the Company. Operating leases have been an important source of financing for our revenue equipment. In accordance with ASC Topic 840, Leases, property and equipment held under operating leases, and liabilities related thereto, are not reflected on our balance sheet. All expenses related to operating leases and related liabilities are reflected in our consolidated income statements under "Rental expense." Rent expense was $240.5 million, $229.3 million and $180.3 million for the years ended 2015, 2014 and 2013, respectively. The total amount of remaining payments under operating leases as of December 31, 2015 was approximately $613.3 million.
As of December 31, 2015, the Company had commitments outstanding to acquire revenue equipment in 2016 for approximately $681.8 million ($484.1 million of which were tractor commitments) and in 2017 to 2018 for approximately $190.9 million (all of which were tractor commitments). The Company has the option to cancel tractor purchase orders with 60 to 90 days' notice prior to the scheduled production, although the notice period has lapsed for approximately 10.1% of the tractor commitments outstanding as of December 31, 2015. These purchases are expected to be financed by the combination of operating leases, capital leases, debt, proceeds from sales of existing equipment and cash flows from operations.
As of December 31, 2015, the Company had outstanding purchase commitments of approximately $13.3 million for facilities and non-revenue equipment. Factors such as costs and opportunities for future terminal expansions may change the amount of such expenditures.
(7)$6.3 million increase in proceeds from common stock issued under our compensatory and non-compensatory stock plans.
(8)$4.1 million net remaining favorable variance was related to various factors that had an immaterial impact on net cash used in financing activities, individually and in aggregate.
Inflation
Inflation can have an impact on our operating costs. A prolonged period of inflation could cause interest rates, fuel, wages, and other costs to increase, which would adversely affect our results of operations unless freight rates correspondingly increased. However, the effect of inflation has been minor over the past three years.
Critical Accounting Estimates
The preparation of our consolidated financial statements in conformity with US-GAAP requires management to make estimates and assumptions that impact the amounts reported in our consolidated financial statements and accompanying notes. Therefore, the reported amounts of assets, liabilities, revenue, expenses, and associated disclosures of contingent assets and liabilities are affected by these estimates and assumptions. We evaluate these estimates and assumptions on an ongoing basis, utilizing historical experience, consultation with experts, and other methods considered reasonable in the particular circumstances. Nevertheless, actual results may differ significantly from our estimates and assumptions, and it is possible that materially different amounts could be reported using differing estimates or assumptions. We consider our critical accounting estimates to be those that require us to make more significant judgments and estimates when we prepare our financial statements.

expense varies as a percentage of operating revenue, based on the frequency and severity of claims incurred in a given period, as well as changes in claims development trends. The actual cost to settle our self-insured claim liabilities may differ from our reserve estimates due to legal costs, claims that have been incurred but not reported, and various other uncertainties, including the inherent difficulty in estimating the severity of the claim and the potential judgment or settlement amount to dispose of the claim. If claims development factors that are based upon historical experience had increased by 10%, our claims accrual as of December 31, 20152016 would have potentially increased by $18.0$12.5 million.
Goodwill and Indefinite-lived Intangible Assets Note 2 to the consolidated financial statements describes the Company's goodwill and indefinite-lived intangible assets accounting policy. The following discussion should be read in conjunction with Note 2, as it presents uncertainties involved in applying the accounting policy, and provides insight into the quality of management's estimates and variability in valuation of goodwill and indefinite-lived intangible assets. The test of goodwill and indefinite-lived intangible assets requires judgment, including the identification of reporting units, assigning assets (including goodwill) and liabilities to reporting units and determining the fair value of each reporting unit. Fair value of the reporting unit is determined using a combination of comparative valuation multiples of publicly traded companies, internal transaction methods, and discounted cash flow models. Estimating the fair value of reporting units includes several significant assumptions, including future cash flow estimates, determination of appropriate discount rates, and other assumptions that management believed reasonable under the circumstances. Changes in these estimates and assumptions could materially affect the determination of fair value and/or goodwill impairment for each reporting unit.
We evaluated goodwill as of November 30, 20152016 and 20142015 using the qualitative factors prescribed in ASC Topic 350 to determine whether to perform the two-step quantitative goodwill impairment test. The assessment of qualitative factors requires judgment, including identification of reporting units, evaluation of macroeconomic conditions, analysis of industry and market conditions, measurement of cost factors, and identification of entity-specific events (such as financial performance and changes within our share price). In evaluating these qualitative factors, we determined that it was more likely than not that fair value exceeded carrying value for our reporting units as of November 30, 20152016 and 2014.2015. As such, it was not necessary to perform the two-step quantitative goodwill impairment test.

Truckload and Dedicated are the only reporting units to which goodwill has been allocated, due to their respective fair value materiality at the time of the 2007 Transactions. As of December 31, 20152016 and 2014,2015, gross goodwill allocated to the Truckload segment was $377.0 million and gross goodwill allocated to the Dedicated segment was $130.7 million. We recognized accumulated impairment losses of $190.4 million in our Truckload reporting unit during 2007 and 2008, $64.1 million in our Dedicated reporting unit during 2007 and no impairment losses thereafter. As of December 31, 20152016 and 20142015 the Truckload reporting unit had a carrying value of $186.6 million and the Dedicated reporting unit had a carrying value of $66.7 million.
Depreciation and Amortization Note 2 to the consolidated financial statements describes the Company's depreciation accounting policy under "Property and Equipment," and the amortization accounting policy under "Intangible Assets, other than Goodwill." The following discussion should be read in conjunction with Note 2, as it presents uncertainties involved in applying the accounting policies, and provides insight into the quality of management's estimates and potential variability in amounts recorded for depreciation and amortization. Selecting the appropriate accounting method requires management judgment, as there are multiple acceptable methods that are in accordance with US-GAAP, including straight-line, declining-balance, and sum-of-the-years' digits. As discussed in Note 2, property and equipment is depreciated on a straight-line basis and intangible customer relationships acquired in the 2007 Transactions are amortized on a 150% double-declining-balance basis over the useful lives of the assets. We believe that these methods properly spread the costs over the useful lives of the assets. Management judgment is also involved when determining estimated useful lives of the Company's long-lived assets. We determine useful lives of our long-lived assets, based on historical experience, as well as future expectations regarding the period we expect to benefit from the asset. Factors affecting estimated useful lives of property and equipment may include estimating loss, damage, obsolescence, and company policies around maintenance and asset replacement. Factors affecting estimated useful lives of long-lived intangible assets may include legal, contractual, or other provisions that limit useful lives, historical experience with similar assets, future expectations of customer relationships, among others.
Impairments of Long-lived Assets Note 2 to the consolidated financial statements describes the Company's accounting policy for long-lived asset impairments under "Property and Equipment," and "Intangible Assets, other than Goodwill." The following discussion should be read in conjunction with Note 2, as it presents uncertainties involved in applying the accounting policies, and provides insight into the quality of management's estimates and potential variability in amounts recorded for asset impairments. Fair value is determined through various valuation techniques, including discounted cash flow models, quoted market values, and third-party independent appraisals, as necessary. Estimating fair value includes several significant assumptions, including future cash flow estimates, determination of appropriate discount rates, and other assumptions that management believed reasonable under the circumstances. Changes in these estimates and assumptions could materially affect the determination of fair value and/or impairment.

Income Taxes Note 2 to the consolidated financial statements describes the Company's income tax accounting policy. The following discussion should be read in conjunction with Note 2, as it presents uncertainties involved in applying the accounting policy, and provides insight into the quality of management's estimates and variability in our deferred tax assets and liabilities. Our deferred tax assets and liabilities represent items that will result in taxable income or tax deductions in future years for which we have already recorded the related tax expense or benefit in our consolidated income statements. Deferred tax accounts arise as a result of timing differences between when items are recognized in our consolidated financial statements compared to when they are recognized in our tax returns. Significant management judgment is required in determining our provision for income taxes and in determining whether deferred tax assets will be realized in full or in part. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. We periodically assess the likelihood that all or some portion of deferred tax assets will be recovered from future taxable income. To the extent we believe the likelihood of recovery is not sufficient, a valuation allowance is established for the amount determined not to be realizable. As of December 31, 2015, we had no
Note 11 to the consolidated financial statements discusses valuation allowance. All deferred tax assets are considered more likely than not to be realized as they are expected to be utilized by continued profitability in future periods.
United States incomeallowances and foreign withholding taxes have not been provided on approximately $25.3 million of cumulative undistributed earnings of foreign subsidiaries. The earnings are considered to be permanently reinvested outside the United States. As the Company intends to reinvest these earnings indefinitely outside the United States, it is not required to provide United States income taxes on them until they are repatriated in the form of dividends or otherwise.earnings.
We believe that we have adequately provided for our future tax consequences based upon current facts and circumstances and current tax law. However, should our tax positions be challenged, different outcomes could result and have a significant impact on the amounts reported through our consolidated income statements.
Operating Leases See "Off Balance Sheet Arrangements,In accordance with ASC Topic 840, Leases, property and equipment held under operating leases, and liabilities related thereto, are off-balance sheet. All expenses related to operating leases are reflected in our consolidated income statements in "Rental expense." above.At the inception of a lease, management judgment is involved in classification as an operating or capital lease, as well as determination of useful lives and estimation of residual values of the related equipment. Future minimum lease payments used in determining lease classification represent the minimum rental payments called for over the lease term, inclusive of residual value guarantees (if applicable) and amounts that would be required to be paid, if any, by the Company upon default for leases containing subjective acceleration or cross default clauses.
The Company does not currently guarantee residual values under its operating lease agreements for revenue equipment. To the extent we believe any manufacturer will refuse or be unable to meet its obligation, we recognize additional rental expense to the extent we believe the fair market value at the lease termination will be less than our obligation to the lessor. We believe that proceeds from the sale of equipment under operating leases would exceed the payment obligation on substantially all operating leases.
Stock-based Compensation Note 2 to the consolidated financial statements describes the Company's stock-based compensation accounting policy. The following discussion should be read in conjunction with Note 2, as it presents uncertainties involved in applying the accounting policy, and provides insight into the quality of management's estimates and variability in stock-based compensation expense. We issue several types of share-based compensation, including awards that vest, based on service and performance conditions or a combination of service and performance conditions. Performance-based awards vest contingent upon meeting certain performance criteria established by our compensation committee. All awards require future service and thus forfeitures are estimated based on historical forfeitures and the remaining term until the related award vests. ASC Topic 718 requires that all share-based payments to employees, including grants of employee stock options, be recognized in the financial statements based upon a grant-date fair value of an award. Determining the appropriate amount to expense in each period is based on likelihood and timing of achievement of the stated targets for performance-based awards, and requires judgment, including forecasting future

financial results and market performance. The estimates are revised periodically, based on the probability and timing of achieving the required performance targets, respectively, and adjustments are made as appropriate. Awards that are only subject to time-vesting provisions are amortized using the straight-line method. Awards subject to time-based vesting and performance conditions are amortized using the individual vesting tranches.

ITEM 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
We have exposure from variable interest rate exposure arising from outstanding debt fromrates, primarily related to our 2015 Agreement, and 2015 RSA, and other financing agreements, which have variable interest rates.RSA. These variable interest rates are impacted by changes in short-term interest rates. We primarily manage interest rate exposure through a mix of variable rate debt (weighted average rate of 1.9%) and 1.9% as of December 31, 2016 and 2015, respectively). Assuming the current level of borrowings, a hypothetical one percentage point increase in interest rates would increase our annual interest expense by $10.9$9.0 million.
We have commodity exposure with respect to fuel used in company-owned tractors. Increases in fuel prices willwould continue to raise our operating costs, even after applying fuel surcharge revenue. Historically, we have been able to recover a majority of fuel price increases from our customers in the form of fuel surcharges. The weekly average diesel price per gallon in the United States, as reported by the DOE, decreased from an average of $3.825$2.71 per gallon for the year ended December 31, 20142015 to $2.707$2.30 per gallon for the year ended December 31, 2015.2016. We cannot predict the extent or speed of potential changes in fuel price levels in the future, the degree to which the lag effect of our fuel surcharge programs will impact us as a result of the timing and magnitude of such changes, or the extent to which effective fuel surcharges can be maintained and collected to offset such increases. We generally have not used derivative financial instruments to hedge our fuel price exposure in the past, but continue to evaluate this possibility.

The Board of Directors and Stockholders
Swift Transportation Company:
We have audited the accompanying consolidated balance sheets of Swift Transportation Company and subsidiaries (the Company) as of December 31, 20152016 and 2014,2015, and the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-yearthree‑year period ended December 31, 2015.2016. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Swift Transportation Company and subsidiaries as of December 31, 20152016 and 2014,2015, and the results of their operations and their cash flows for each of the years in the three-yearthree‑year period ended December 31, 2015,2016, in conformity with U.S. generally accepted accounting principles.
As discussed in note 3 to the consolidated financial statements, the Company has adopted, on a retrospective basis, FASB Accounting Standards Update No. 2015-17, Balance Sheet Classification of Deferred Taxes classifying all deferred tax assets, liabilities and associated allowances as non-current.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial reporting as of December 31, 2015,2016, based on criteria established inInternal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated February 22, 201617, 2017 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Without this change in estimate, basic and diluted earnings per share would have been $0.05 higher for the year ended December 31, 2016.
In October 2016, the Company acquired allchanged its estimated residual values on certain trailers. This accelerated the depreciation on some trailers, while decelerating the depreciation on others. Management prospectively accounted for this as a change in accounting estimate. The impact on "Depreciation and amortization of property and equipment" was a decrease of approximately $0.6 million. Without this change in estimate, basic and diluted earnings per share would have been unaffected for the year ended December 31, 2016.
Changes in Presentation
Beginning in 2016, the Company made the following changes in presentation:
In April 2015, FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, which amended ASC Subtopic 835-30, Interest – Imputation of Interest. The amendments in this ASU simplify the presentation of debt issuance costs and align the presentation with debt discounts. Entities are required to present debt issuance costs within liabilities as a direct deduction from the face amount of the outstanding capital stockrelated debt, rather than as a deferred charge within assets. In August 2015, FASB issued ASU 2015-15, Presentation and Subsequent Measurement of Central for aggregate considerationDebt Issuance Costs Associated with Line-of-Credit Arrangements – Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting (SEC Update), which also amended ASC Subtopic 835-30, Interest – Imputation of approximately $225.0 million.Interest. The Company paid approximately $189.0 millionSEC determined that ASU 2015-03 (discussed above) did not address costs related to line-of-credit arrangements. The amendments in cash toASU 2015-15 clarify that entities may defer and present debt issuance costs as an asset, and subsequently amortize the stockholdersdeferred debt issuance costs ratably over the term of Central and assumed approximately $36.0 millionthe line-of-credit arrangement, regardless of capital lease obligations and other debt. Cash consideration was primarily funded fromwhether there are any outstanding borrowings on the line-of-credit arrangement. The amendments in these ASUs require retrospective application, with related disclosures for a change in accounting principle. For public business entities, the amendments in these ASUs were effective for financial statements issued for fiscal years beginning after December 15, 2015, and the interim periods within those fiscal years, with early adoption permitted.

Note 2 — Summary of Significant Accounting Policies
Use of Estimates — The preparation of the consolidated financial statements, in accordance with US-GAAP, requires management to make estimates and assumptions about future events that affect the amounts reported in the Company’sCompany's consolidated financial statements and accompanying notes. On an ongoing basis, management evaluates and periodically adjusts its estimates and assumptions, based on historical experience, the impact of the current economic environment, and other key factors. Volatile energy markets, as well as changes in consumer spending have increased the inherent uncertainty in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Significant items subject to such estimates and assumptions include:
carrying amount of property and equipment, intangibles, and goodwill;
valuation allowances for receivables, inventories, and deferred income tax assets;
valuation of financial instruments;
calculation of share-basedstock-based compensation;
estimates of claims accruals;
leases, and
contingent obligations.
Segments — The Company uses the "management approach" to determine its reportable segments, as well as to determine the basis of reporting the operating segment information. The management approach focuses on financial information that management uses to make operating decisions. TheOur CODMs use operating revenues, operating expense categories, operating ratios, operating income, and key operating statistics to evaluate performance and allocate resources to the Company’sCompany's operations.
Operating income is the measure of segment profit or lossthat management uses to evaluate segment performance and allocate resources, which is consistent with US-GAAP for segment reporting. It is the Company’s measure of segment performance. Operating income should not be viewed as a substitute for US-GAAP net income (loss). Management believes the presentation of operating income enhances the understanding of the Company's performance

SWIFT TRANSPORTATION COMPANY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED

by highlighting the results of operations and the underlying profitability drivers of the business segments. Operating income is defined as operating revenues less operating expenses, before income tax expense.
Based on the unique nature of the Company's operating structure, revenue-generating assets are interchangeable between segments. Therefore, the Company does not prepare separate balance sheets by segment, as assets are not separately identifiable by segment. The Company allocates depreciation and amortization expense onof its property and equipment to the segments based on the actual utilization of the asset by the segment during the period.
Cash and Cash Equivalents — The Company considers all highly liquid debt instruments purchased with original maturities of three months or less to be cash equivalents.
Restricted Cash — The Company’sCompany's wholly-owned captive insurance companies, Red Rock and Mohave, maintain certain operating bank accounts, working trust accounts, and investment accounts. The cash and short-term investments within the accounts are restricted by insurance regulations to fund the insurance claim losses to be paid by the captive insurance companies. Therefore, these cash and short-term investments are classified as "Restricted cash""Cash and cash equivalents restricted" in the consolidated balance sheets.
Restricted Investments — The Company's investments are restricted by insurance regulations to fund the insurance claim losses to be paid by the captive insurance companies. The Company accounts for its investments in accordance with ASC Topic 320, Investments – Debt and Equity Securities. Management determines the appropriate classification of its investments in debt securities at the time of purchase and re-evaluates the determination on a quarterly basis. As of December 31, 2015,2016, all of the Company’sCompany's investments in fixed-maturity securities were classified as held-to-maturity, as the Company has the positive intent and ability to hold these securities to maturity. Held-to-maturity securities are carried at amortized cost. The amortized cost of debt securities is adjusted using the effective interest rate method for amortization of premiums and accretion of discounts. Amortization and accretion is reported in "Other expenses (income)"income, net" in the consolidated income statements.
Management periodically evaluates restricted investments for impairment. The assessment of whether impairments have occurred is based on management’smanagement's case-by-case evaluation of the underlying reasons for the decline in estimated fair value. Management accounts for other-than-temporary impairments of debt securities in accordance with ASC Topic 320, Investments – Debt and Equity Securities. This guidance requires the Company to evaluate whether it intends to sell an impaired debt security or whether it is more likely than not that it will be required to sell an impaired debt security before recovery of the amortized cost basis. If either of these criteria are met, an impairment loss equal to the difference between the debt security’ssecurity's amortized cost and its estimated fair value is recognized in earnings. For impaired debt securities that do not meet these criteria, the Company determines if a credit loss exists with respect to the impaired security. If a credit loss exists, the credit loss component of the impairment (i.e., the difference

SWIFT TRANSPORTATION COMPANY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED

between the security’ssecurity's amortized cost and the present value of projected future cash flows expected to be collected) is recognized in earnings and the remaining portion of the impairment is recognized as a component of AOCI.
Inventories and Supplies — Inventories and supplies primarily consist of spare parts, tires, fuel, and supplies and are stated at lower of cost or market. Cost is determined using the first-in, first-out method.
Property and Equipment — Property and equipment are stated at cost. Costs to construct significant assets include capitalized interest incurred during the construction and development period. Expenditures for replacements and improvements are capitalized. Maintenance and repairs are expensed as incurred.
Depreciation onof property and equipment is calculated on a straight-line basis over the following estimated useful lives:
Category Range
Facilities and improvements 3to40 years
Revenue and service equipment 32to20 years
Furniture and office equipment 3to5 years
Net gains on the disposal of property and equipment are presented in the consolidated income statements within operating income.
Tires on purchased revenue equipment are capitalized along with the related equipment cost when the vehicle is placed in service and depreciated over the life of the vehicle. Replacement tires are classified as inventory and expensed when placed in service.
Management evaluates its property and equipment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable in accordance with ASC Topic 360, Property, Plant and Equipment. When such events or changes in circumstances occur, management performs a recoverability test that compares the carrying amount with the projected undiscounted cash flows from the use and eventual disposition of the asset or asset group. An impairment is recorded for any excess of the carrying amount over the estimated fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary.

Intangible Assets other than Goodwill — The Company’sCompany's intangible assets other than goodwill primarily consist of acquired customer relationships and trade names. Amortization of acquired customer relationships is calculated on the 150% declining balance method over the estimated useful life of 15 years. The customer relationship contributed to the Company at May 9, 2007 is amortized over 15 years on a straight-line basis. The trade name has an indefinite useful life and is not amortized, but is tested for impairment at least annually, unless events occur or circumstances change between annual tests that would more likely than not reduce the fair value.
Management reviews its intangible assets for impairment whenever events or circumstances indicate that the carrying amount of the asset may not be recoverable, in accordance with ASC Topic 350, Intangibles – Goodwill and Other. When such events or changes in circumstances occur, management performs a recoverability test that compares the carrying amount with the projected undiscounted cash flows from the use and eventual disposition of the asset or asset group. An impairment is recorded for any excess of the carrying amount over the estimated fair value, which is generally determined using discounted future cash flows.
Goodwill — Management evaluates goodwill on an annual basis as of November 30th, or more frequently if indicators of impairment exist. The Company assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than the carrying amount. If the Company concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company conducts a two-step quantitative goodwill impairment test. The first step of the quantitative impairment test involves comparing the fair values of the applicable reporting units with their carrying values. Management estimates the fair values of its reporting units using a combination of the income and market approaches. If the carrying amount of a reporting unit exceeds the reporting unit’sunit's fair value, then management performs the second step of the goodwillquantitative impairment test. The second step of the goodwillquantitative impairment test involves comparing the implied fair value of the affected reporting unit’sunit's goodwill with the carrying value of that goodwill. Any amount by which the carrying value of the goodwill exceeds its implied fair value is recognized as an impairment loss. Refer to Note 8 for discussion of the results of the Company's annual evaluation as of November 30, 2015.2016.
Claims Accruals — The Company is self-insured for a portion of its risk related to auto liability, workers’workers' compensation, property damage, and cargo damage risk and employer medical expense priordamage. Prior to January 1, 2015. This self-insurance2015, the Company was also self-insured for a portion of its employer medical expense. Self-insurance results from buying insurance coverage that applies in excess of a retained portion of risk for each respective line of coverage. The Company accrues for the cost of the uninsured portion of pending claims by evaluating the nature and severity of individual claims and by estimating future claims development based upon historical claims development trends. The actual cost to settle our self-insured claim liabilities may differ from our reserve estimates due to legal costs, claims that have been incurred but not reported and various other uncertainties, including the inherent difficulty in estimating the severity of the claims and the potential judgment or settlement amount to dispose of the claim.

Fair Value Measurements — See Note 2421 for accounting policies and financial information relating to fair value measurements.
Contingencies — See Note 17 for accounting policies and financial information related to contingencies.
Revenue Recognition — The Company recognizes operating revenues and the related direct costs of such revenue as of the date the freight is delivered, in accordance with ASC Topic 605-20-25-13, Services for Freight-in-Transit at the End of a Reporting Period.
The Company recognizes operating lease revenue from leasing tractors and related equipment to owner-operators. Operating lease revenue from rental operations is recognized as earned, which is straight-lined per the rent schedules in the lease agreements. Losses from lease defaults are recognized as offsets to revenue.
Stock-based Compensation — The Company accounts for stock-based compensation expense in accordance with ASC Topic 718, Compensation – Stock Compensation. ASC Topic 718 requires that all share-based payments to employees and non-employee directors, including grants of employee stock options, be recognized in the financial statements based upon a grant-date fair value of an award. The Company calculates the number of awards expected to vest as awards granted, less expected forfeitures over the life of the award (estimated at grant date). Compensation expense is recorded based on amortization of the grant-date fair value over a graded vesting period. Unless a material deviation from the assumed forfeiture rate is observed during the term in which the awards are expensed, any adjustment necessary to reflect differences in actual experience is recognized in the period the award becomes payable or exercisable. See Note 1719 for additional information relating to the Company’sCompany's stock compensation plan.
Income Taxes — Management accounts for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to operating loss and tax credit carryforwards, as well as differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Net deferred incomes taxes are classified as noncurrent in the consolidated balance sheets. The effect on deferred tax assets and liabilities of changes in tax rates is recognized in income in the period that includes the enactment date.

A valuation allowance is provided against deferred tax assets if the Company determines it is more likely than not that such assets will not ultimately be realized.
The Company does not recognize a tax benefit for uncertain tax positions unless it concludes that it is more likely than not that the benefit will be sustained on audit by the taxing authority based solely on the technical merits of the associated tax position. If the recognition threshold is met, the Company recognizes a tax benefit measured at the largest amount of the tax benefit that, in the management's judgment, is greater than 50% likely to be realized. The Company records expected incurred interest and penalties related to unrecognized tax positions in "Income tax expense" in the consolidated income statements.

Note 3 — Recently Issued Accounting Pronouncements
In November 2015, FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes, which amends ASC Topic 740, Income Taxes. The amendments in this ASU simplify balance sheet presentation by establishing the requirement that deferred income taxes must be classified as noncurrent.  The amendments in this ASU do not change the requirement that deferred tax liabilities and assets should be presented on a net basis.  For public business entities, the amendments in this ASU are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods.  Earlier application is permitted for all entities as of the beginning of an interim or annual reporting period.  The amendments in this ASU may be applied to all deferred tax liabilities and assets either prospectively or retrospectively to all periods presented.  The Company early-adopted the guidance at December 31, 2015 and retrospectively adjusted the December 31, 2014 presentation by reclassifying a $43.3 million net current deferred tax asset ($44.9 million from the current asset "Deferred income taxes," net of a $1.6 million current deferred tax liability from "Accrued liabilities") into the net noncurrent liability "Deferred income taxes."
In August 2015, FASB issued ASU 2015-14, Deferral of the Effective Date, which amends ASC Topic 606, Revenue from Contracts with Customers.

that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The amendments in this ASU may be applied retrospectively to each period presented, or as a cumulative effect adjustment as of the date of adoption. Management is currently evaluating the accounting, transition and disclosure requirements of the standard and expects to know the financial statement impact upon adoption in 2018.
In July 2015, FASB issued ASU 2015-11, Simplifying the Measurement of Inventory, which amends ASC Topic 330, Inventory. The amendments in this ASU simplify subsequent measurement of inventory for all inventory measurement methods, except for last-in-first-out and retail inventory methods. Current guidance requires entities to measure inventory at the lower of cost or market. However, market could be the replacement cost, net realizable value, or net realizable value less an approximately normal profit margin. The new guidance requires entities to measure inventory at the lower of cost and net realizable value, instead of the previously issued guidance of lower of cost or market. FASB defines net realizable value as estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. For public business entities, the amendments in this ASU are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The amendments should be applied prospectively. Although early adoption is permitted, the Company expects to adopt this guidance at the beginning of 2017. However, due to the nature of the Company's inventory balances (spare parts, tires, fuel and supplies), inventory is predominantly stated at cost, which is consistently below net realizable value. As such, the amendments in this ASU are not expected to have a material impact on the Company's financial position or results of operations upon adoption.
In April 2015, FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, which amends ASC Subtopic 835-30, Interest — Imputation of Interest. The amendments in this ASU simplify the presentation of debt issuance costs and align the presentation with debt discounts. Entities will be required to present debt issuance costs as a direct deduction from the face amount of the related note, rather than as a deferred charge. In August 2015, FASB issued ASU 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting (SEC Update), which also amends ASC Subtopic 835-30, Interest — Imputation of Interest. The SEC determined that ASU 2015-03 (discussed above) did not address costs related to line-of-credit arrangements. The amendments in ASU 2015-15 clarify that entities may defer and present debt issuance costs as an asset, and subsequently amortize the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The amendments in these ASUs require retrospective application, with related disclosures for a change in accounting principle. Upon adoption, the Company will comply with these disclosure requirements by providing the nature and reason for the change, the transition method, a description of the adjusted prior period information and the effect of the change on the financial statement line items. For public business entities, the amendments in these ASUs will be effective for financial statements issued for fiscal years beginning after December 15, 2015, and the interim periods within those fiscal years. Early adoption is permitted; however, the Company expects to adopt this guidance at the beginning of 2016. Upon adoption, the amended guidance will affect Swift's classification of debt issuance costs, which are currently classified in "Other assets" in the consolidated balance sheets. In accordance with the amendments in ASU 2015-15, debt issuance costs associated with the revolving line of credit will remain within "Other assets" in the consolidated balance sheets. All other debt issuance costs will be reclassified, in accordance with the amendments in ASU 2015-03. This reclassification of debt issuance costs will effectively decrease "Other assets" by approximately $2.6 million and correspondingly decrease the long-term debt balances by the same amount.
In February 2015, FASB issued ASU 2015-02, Amendments to the Consolidation Analysis, which amends ASC Topic 810, Consolidation, by changing the analysis that reporting entities are required to perform to determine whether certain types of legal entities should be consolidated. The amendments in this ASU focus on limited partnerships and similar legal entities (such as limited liability companies); however, all legal entities are subject to reevaluation under the revised consolidation model. The revised consolidation model modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities or voting interest entities, and eliminates the presumption that a general partner should consolidate a limited partnership. It also affects the consolidation analysis of reporting entities that are involved with variable interest entities, especially those that have fee arrangements and related-party relationships. The amendments in the ASU also affect certain investment funds. For public business entities, the amendments in this ASU are effective for fiscal years beginning after December 15, 2015, and the interim periods within those fiscal years. Early adoption is permitted. Entities may use a retrospective approach, or a modified retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the year of adoption. The Company is currently evaluating the accounting, transition and disclosure requirements of the standard; however, the amendments in this ASU are not expected to have a material impact on the Company's financial position or results of operations upon adoption.

Due to the nature of the Company's inventory balances (spare parts, tires, fuel, and supplies), inventory is predominantly stated at cost.
____________
(1)
Management is in the diagnostic phase of assessing the financial and business impacts of implementing ASC Topic 606, Revenue from Contracts with Customers, including identifying revenue sources within the Company's lines of business, reviewing a sample of contracts, and developing a preliminary assessment. Based upon these preliminary procedures, management anticipates that the following key considerations will impact the Company's accounting and reporting under the new standard:
identification of what constitutes a contract in Swift's business practices,
variability in individual contracts, such as customer-specific terms that may vary from the master agreement,
principal versus agent determinations,
timing of revenue recognition (for example, point-in-time versus over time and/or accelerated versus deferred),
single versus multiple performance obligations,
new/changed estimates and management judgments (for example, system estimation of in-transit accruals versus manual estimation),
disaggregation of revenue by category within segments, and
others.
Management expects that there will also be changes in sales, contracting, accounting, reporting, tax, debt covenants, and other business processes, policies, and controls, as a result of implementing ASC Topic 606. The Company is currently underway with implementing a new ERP system, which will also affect the implementation process.

SWIFT TRANSPORTATION COMPANY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED

Based on the information currently available from the diagnostic phase, management cannot yet determine the quantitative impact on the financial statements; however, the impact is expected to be immaterial (potentially with changes only to the timing of revenue recognition between reportable periods, as well as changes in the requirements for accounting policy and other new disclosures). The financial impact is expected to be quantifiable by the time the Company files its first Quarterly Report on Form 10-Q in 2017, at which time the Company will be transitioning into the design and planning phase of implementing ASC Topic 606. Since we are continuing to evaluate the impact of ASC Topic 606, our disclosures around our preliminary assessments are subject to change.
(2)
The amendments to ASC Topic 718, Compensation – Stock Compensation, that are expected to affect the Company are discussed below.
Accounting for Income Tax Benefits/Deficiencies: All excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) should be recognized as income tax expense or benefit in the income statement. The tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. An entity should also recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. Modified retrospective application is required, by means of a cumulative-effect adjustment to equity.
Upon adoption, the Company will need to reclassify approximately $16.8 million in historical net tax benefit/deficiency amounts previously recorded within additional paid-in capital into retained earnings/accumulated deficit. Going forward, tax benefit/deficiency amounts will be recorded in net income.
Classification of Excess Tax Benefits on the Statement of Cash Flows: Excess tax benefits should be classified along with other income tax cash flows as an operating activity. Application is permitted to be prospective or retrospective.
Current GAAP requires classification within cash flows from financing activities. The Company presents its statement of cash flows using the indirect method, which presents excess tax benefits within cash flows from financing activities and a corresponding offset within the net income reconciliation of cash flows from operating activities. As such, the Company will need to reclassify the excess tax benefit amounts out of cash flows from financing activities and into cash flows from operating activities, upon adoption. Management expects to apply these amendments retrospectively.
Forfeitures: An entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest (current GAAP) or account for forfeitures when they occur. Modified retrospective application is required, by means of a cumulative-effect adjustment to equity.
Upon adoption, the Company expects to transition to accounting for forfeitures when they occur. This would result in approximately a $2.5 million unfavorable cumulative-effect adjustment to retained earnings/accumulated deficit to catch-up the previously unrecognized stock-based compensation associated with historical assumed forfeiture rates. Going forward, forfeitures will be recorded as favorable adjustments to stock-based compensation as they occur.
Classification of Employee Taxes Paid on the Statement of Cash Flows When an Employer Withholds Shares for Tax-withholding purposes: Cash paid by an employer when directly withholding shares for tax-withholding purposes should be classified as a financing activity. Retrospective application is required.
Beginning in 2016, the Company began allowing certain members of management to have shares withheld for taxes when their restricted stock awards and performance units vest. As such, upon adopting the amendments in this ASU, the Company will need to present the amounts out of cash flows from operating activities and into cash flows from financing activities for the periods presented. For 2016, the amount was approximately $0.5 million.

Domestic Production Activities Deduction —Internal Revenue Code Section 199 permits taxpayers to claim a deduction from taxable income attributable to certain domestic production activities such as the development of computer software and the manufacturing of goods. Beginning in 2010 and thereafter, the deduction is equal to 9% of the smaller of a taxpayer’s qualified production activities or taxable income. Due to its increased software development efforts, the Company has elected to take the deduction in the current year and preceding open tax years. The decrease in the effective tax rate for the year ended December 31, 2016 was partially attributable to a domestic production activities deduction on the Company's 2015 federal tax return. The Company also received tax benefits for years ending December 31, 2016, December 31, 2014, and December 31, 2013. The Company generated $6.4 million, $6.2 million, $6.2 million, and $3.4 million in domestic production activities deductions for the development of computer software in 2016, 2015, 2014, and 2013, respectively. This resulted in approximately $2.2 million, $2.2 million, $2.2 million, and $1.2 million in tax benefits in 2016, 2015, 2014, and 2013, respectively.

The decrease in the effective tax rate for the year ended December 31, 2016 was partially attributable to the toll road income tax credit reported on the 2015 income tax return. Trans-Mex also will claim a toll road income tax credit for 2016. Trans-Mex paid $5.6 million and $6.5 million in qualifying tolls during 2016 and 2015, respectively. This resulted in approximately $1.8 million and $2.3 million in tax benefits in 2016 and 2015, respectively.

Note 1517 — Contingencies and Legal Proceedings
Accounting Policy
The Company is involved in certain claims and pending litigation primarily arising in the normal course of business. The majority of these claims relate to workersworkers' compensation, auto collision and liability, and physical damage, and cargo damage. The Company expenses legal fees as incurred and accrues for the uninsured portion of contingentclaims losses from these and the gross amount of other pending claimslosses when itthe likelihood of the loss is both probable that a liability has been incurred and the amount of the loss canis reasonably estimable. These accruals are based on management's best estimate within a possible range of loss. When there is no amount within the range of loss that appears to be a better estimate than any other amount, then management accrues to the low end of the range. Legal fees are expensed as incurred.
When it is reasonably estimated. possible that exposure exists in excess of the related accrual (which could be no accrual), management discloses an estimate of the possible loss or range of loss, unless an estimate cannot be determined.
If the likelihood of a loss is remote, the Company does not accrue for the loss. However if the likelihood of a loss is remote, but it is at least reasonably possible that one or more future confirming events may materially change management's estimate within twelve months from the date of the financial statements, management discloses an estimate of the possible loss or range of loss, unless an estimate cannot be determined.
Legal Proceedings
Information is provided below regarding the nature, status, and contingent loss amounts, if any, associated with the Company's pending legal matters. There are inherent uncertainties in these legal matters, some of which are beyond management's control, making the ultimate outcomes difficult to predict. Moreover, management's views and estimates related to these matters may change in the future, as new events and circumstances arise and the matters continue to develop.
For the matters below, an estimate of the possible loss or range of loss cannot be determined for certain cases because, among other reasons, (1) the proceedings are in various stages that do not allow for assessment; (2) damages have not been sought; (3) damages are unsupported and/or exaggerated; (4) there is uncertainty as to the outcome of pending appeals; and/or (5) there are significant factual issues to be resolved.
Based on the knowledge of the factscurrently available information, and in certain cases, advice of outside counsel, management believes the resolution of claims anddoes not believe that loss contingencies arising from pending litigation, taking into account existing reserves,matters will not have a material adverse effect on the Company. Moreover, the results of complex legal proceedings are difficult to predict and the Company’s view of these matters may change in the future as the litigation and events related thereto unfold.
For certain cases described below, management is unable to provide a meaningful estimate of the possible loss or range of loss because, among other reasons, (i) the proceedings are in various stages; (ii) damages have not been sought; (iii) damages are unsupported and/or exaggerated; (iv) there is uncertainty as to the outcome of pending appeals and/or (v) there are significant factual issues to be resolved.  For these cases, however, management does not believe, based on currently available information, that the outcomes of these proceedings will have a material adverse effect on ourCompany's overall financial condition, though theposition, after taking into consideration any existing accruals. However, actual outcomes could be material to ourthe Company's operating results or liquidity for any particular period, depending, in part, upon the operating results for such period.
Arizona Owner-operator Class Action Litigation
On January 30, 2004, a class action lawsuit was filed by Leonel Garza on behalf of himself and all similarly-situated persons against Swift Transportation: Garza v. Swift Transportation Co., Inc., Case No. CV7-472 (the "Garza Complaint"). The putative class originally involved certain owner-operators who contracted with the Company under a 2001 Contractor Agreement that was in place for one year. The putative class is alleging that the Company should have reimbursed owner-operators for actual miles driven rather than

the contracted and industry standard remuneration based upon dispatched miles. The trial court denied plaintiff’s petition for class certification. The plaintiff appealed and on August 6, 2008, the Arizona Court of Appeals issued an unpublished Memorandum Decision reversing the trial court’s denial of class certification and remanding the case back to the trial court. On November 14, 2008, the Company filed a petition for review to the Arizona Supreme Court regarding the issue of class certification as a consequence of the denial of the Motion for Reconsideration by the Court of Appeals. On March 17, 2009, the Arizona Supreme Court granted the Company’s petition for review, and on July 31, 2009, the Arizona Supreme Court vacated the decision of the Court of Appeals, opining that the Court of Appeals lacked automatic appellate jurisdiction to reverse the trial court’s original denial of class certification and remanded the matter back to the trial court for further evaluation and determination. Thereafter, the plaintiff renewed the motion for class certification and expanded it to include all persons who were employed by Swift as employee drivers or who contracted with Swift as owner-operators on or after January 30, 1998, in each case who were compensated by reference to miles driven. On November 4, 2010, the Maricopa County trial court entered an order certifying a class of owner-operators and expanding the class to include employees. Upon certification, the Company filed a motion to compel arbitration, as well as filing numerous motions in the trial court urging dismissal on several other grounds including, but not limited to the lack of an employee as a class representative, and because the named owner-operator class representative only contracted with the Company for a three-month period under a one-year contract that no longer exists. In addition to these trial court motions, the Company also filed a petition for special action with the Arizona Court of Appeals, arguing that the trial court erred in certifying the class because the trial court relied upon the Court of Appeals ruling that was previously overturned by the Arizona Supreme Court. On April 7, 2011, the Arizona Court of Appeals declined jurisdiction to hear this petition for special action and the Company filed a petition for review to the Arizona Supreme Court. On August 31, 2011, the Arizona Supreme Court declined to review the decision of the Arizona Court of Appeals. In April 2012, the trial court issued the following rulings with respect to certain motions filed by Swift: (1) denied Swift’s motion to compel arbitration; (2) denied Swift’s request to decertify the class; (3) granted Swift’s motion that there is no breach of contract; and (4) granted Swift’s motion to limit class size based on statute of limitations. On November 13, 2014, the court denied plaintiff's motion to add new class representatives for the employee class and therefore the employee class remains without a plaintiff class representative. On March 18, 2015, the court denied Swift's two motions for summary judgment (1) to dismiss any claims related to the employee class since there is no class representative; and (2) to dismiss plaintiff's claim of breach of a duty of good faith and fair dealing. On July 14, 2015, the court granted Swift's motion to decertify the entire class. On December 23, 2015, Plaintiff filed a Petition for Special Action with the Arizona Court of appeals. That petition has been fully briefed and oral argument is scheduled for February 17, 2016.
Ninth Circuit Owner-Operator Misclassification Class Action Litigation
On December 22, 2009, a class action lawsuit was filed against Swift Transportation and IEL: Virginia VanDusen, John Doe 1 and Joseph Sheer, individually and on behalf of all other similarly-situated persons v. Swift Transportation Co., Inc., Interstate Equipment Leasing, Inc., Jerry Moyes, and Chad Killebrew, Case No. 9-CIV-10376 filed in the United States District Court for the Southern District of New York (the "Sheer Complaint"). The putative class involves owner-operators alleging that Swift Transportation misclassified owner-operators as independent contractors in violation of the federal Fair Labor Standards Act ("FLSA"), and various New York and California state laws and that such owner-operators should be considered employees. The lawsuit also raises certain related issues with respect to the lease agreements that certain owner-operators have entered into with IEL. At present, in addition to the named plaintiffs, approximately 450 other current or former owner-operators have joined this lawsuit. Upon Swift’s motion, the matter was transferred from the United States District Court for the Southern District of New York to the United States District Court in Arizona. On May 10, 2010, the plaintiffs filed a motion to conditionally certify an FLSA collective action and authorize notice to the potential class members. On September 23, 2010, plaintiffs filed a motion for a preliminary injunction seeking to enjoin Swift and IEL from collecting payments from plaintiffs who are in default under their lease agreements and related relief. On September 30, 2010, the district court granted Swift’s motion to compel arbitration and ordered that the class action be stayed, pending the outcome of arbitration. The district court further denied plaintiff’s motion for preliminary injunction and motion for conditional class certification. The district court also denied plaintiff’s request to arbitrate the matter as a class.
California Wage, Meal, and Rest: Driver Class Actions
The plaintiffs generally allege one or more of the following: that the Company 1) failed to pay the California minimum wage; 2) failed to provide proper meal and rest periods; 3) failed to timely pay wages upon separation from employment; 4) failed to pay for all hours worked; 5) failed to pay overtime; 6) failed to properly reimburse work-related expenses; and 7) failed to provide accurate wage statements.

In May 2016, the Burnell plaintiffs were denied class certification. Their subsequent petition to appeal the decertification order was also denied. Following the Burnell plaintiffs' failure to certify the class, the stays on certain cases were lifted. Those cases are now in discovery.

The likelihood that a loss has been incurred is remote.
California Wage, Meal, and Rest: Yard Hostler Class Actions
The plaintiffs, representing yard hostlers employed by the Company in California, generally allege one or more of the following: that the Company 1) failed to pay minimum wage; 2) failed to pay overtime and doubletime wages required by California law; 3) failed to provide accurate, itemized wage statements; 4) failed to timely pay wages upon separation from employment; 5) failed to reimburse for business expenses; and 6) failed to provide proper meal and rest periods.

The plaintiff filed a petition for a writ of mandamus to the Ninth Circuit Court of Appeals asking that the district court’s September 30, 2010 order be vacated. On July 27, 2011, the Ninth Circuit Court of Appeals denied the plaintiff’s petition for writ of mandamus and thereafter the district court denied plaintiff’s motion for reconsideration and certified its September 30, 2010 order. The plaintiffs filed an interlocutory appeal to the Ninth Circuit Court of Appeals to overturn the district court’s September 30, 2010 order to compel arbitration, alleging that the agreement to arbitrate is exempt from arbitration under Section 1 of the Federal Arbitration Act ("FAA") because the class of plaintiffs allegedly consists of employees exempt from arbitration agreements. On November 6, 2013, the Ninth Circuit Court of Appeals reversed and remanded, stating its prior published decision, "expressly held that a district court must determine whether an agreement for arbitration is exempt from arbitration under Section 1 of the FAA as a threshold matter." As a consequence of this determination by the Ninth Circuit Court of Appeals being different from a decision of the Eighth Circuit Court of Appeals on a similar issue, on February 4, 2014, the Company filed a petition for writ of certiorari to the United States Supreme Court to address whether the district court or arbitrator should determine whether the contract is an employment contract exempt from Section 1 of the Federal Arbitration Act. On June 16, 2014, the United States Supreme Court denied the Company’s petition for writ of certiorari.
The matter remains pending in the district court and is currently in discovery. The Company also filed a writ of mandamus and appeal from the district court's order that effectively denied the Company's motion to compel arbitration. The Ninth Circuit held oral

On October 24, 2014, upon motion by Swift, the matter was removed to the United States District Court for the Central District of California, Case No. 14-CV-02206-VAP.

Recent Developments and Current Status
The original trial court's decision was to deny class certification of the owner-operators, which was reversed and reinstated several times by various courts prior to 2016. The class is currently certified, based on an appellate court's decision from July 2016. The Company filed a petition for review with the Arizona Supreme Court in August 2016, which was denied in January 2017. The matter will now proceed in the Maricopa County Superior Court. The final disposition of the matter and impact to the filing of the lawsuit, and through the present, and alleges that they were not paid minimum wage and overtime in accordance with Washington state law and that they suffered unlawful deductions from wages. On November 23, 2013, the court entered an order on plaintiffs' motion to certify the class. The court only certified the class as it pertains to "dedicated" drivers and did not certify any other class, including any class related to over-the-road drivers. The parties dispute the definition of "dedicated" as used by the court and a class notice has not yet been issued. On September 2, 2015, new counsel was appointed for Plaintiffs and on November 16, 2015, new legal counsel was substituted for the Company. As a result of the substitution of counsel for both parties, the court has extended all existing dates by ten months. The matter is now anticipated to move into discovery. The Company retains all of its defenses against liability and damages. The Company intends to vigorously defend against the merits of these claims and to challenge certification.

Recent Developments and Current Status
For several years, the parties have been arguing over the proper venue in which to proceed. The plaintiffs argue that they signed contracts of employment, thus exempting them from arbitration under the Federal Arbitration Act, and claim that their case should be heard in court by a judge. The Company takes the position that these individuals signed independent contractor agreements and therefore can properly be required to submit their claims to arbitration. In January 2017, the district court issued an order finding that the plaintiffs had signed contracts of employment and thus the case could properly proceed in court. The Company has appealed this decision to the Ninth Circuit and will seek to stay the district court case, pending resolution of the appeal. The Company intends to vigorously defend against any proceedings. The final disposition of the matter and impact to the Company cannot be determined at this time.

Through this action, the plaintiffs alleged that the Central Parties misclassified owner-operator drivers as independent contractors and were therefore liable to these drivers for minimum wages and other employee benefits under the FLSA. The complaint also alleged a federal forced labor claim under 18 U.S.C. § 1589 and 1595, as well as fraud and other state-law claims.
Pursuant to the plaintiffs' owner-operator agreements, the district court issued an Order compelling arbitration and directed that the plaintiffs' causes of action under the FLSA should proceed to collective arbitration, while their forced labor, fraud and state law claims would proceed as separate individual arbitrations. A collective arbitration was subsequently initiated with the American Arbitration Association ("AAA"). Notice of the collective arbitration was sent to more than 3,000 owner-operators who worked for Central Refrigerated Service, Inc. and leased a vehicle from Central Leasing, Inc. on or after June 1, 2009. The parties are currently conducting discovery. No trial date has been set by the arbitrator.
In addition to the collective arbitration that is pending before the AAA, the three named plaintiffs, along with approximately 400 other owner-operators, have initiated a series of individual, bilateral proceedings against the Central Parties with the AAA. Discovery is commencing in these individual cases, which are pending before approximately 30 separate arbitrators. Trial dates for these arbitrations are expected to begin in late 2016.
Upon the acquisition of Central Refrigerated by Swift Transportation Company, the plaintiffs in both the collective and individual actions were allowed to amend their complaints in June 2015 to include Swift Transportation Company as a defendant. The Company and the Central Parties intend to vigorously defend against the merits of plaintiffs' claims in both the collective and individual arbitration proceedings. The final disposition of this case and the impact cannot be determined at this time.
California Class and Collective Action for Pre-employment Physical Testing
On October 6, 2014 Robin Anderson filed a putative class and collective action against Central Refrigerated Service, Inc., ("Central Refrigerated") Case No. 5:14-CV 02062 in the United States District Court for the Central District of California (the "Anderson Complaint"). In this action, plaintiff alleges that pre-employment tests of physical strength administered by a third party on behalf of Central Refrigerated had an unlawfully discriminatory impact on female applicants and applicants over the age of 40. The suit seeks damages under Title VII of the Civil Rights Act of 1964, the Age Discrimination Act, and parallel California state law provisions, including the California Fair Employment and Housing Act.

Upon the acquisition
Utah Collective and Individual Arbitration
The plaintiffs allege that the Central Parties (defined below) misclassified owner-operator drivers as independent contractors and were therefore liable to these drivers for minimum wages and other employee benefits under the FLSA. The complaint also alleges a federal forced labor claim under U.S.C. §1589 and §1595, as well as fraud and other state-law claims.

Recent Developments and Current Status
In June 2016, mediation commenced, but there was ultimately no settlement of the matter. In October 2016, the arbitrator ruled that approximately 1,300 Central Refrigerated Service, Inc. drivers were misclassified as independent contractors, and should have been compensated as employees. The arbitrator ruled that damages could be assessed in a collective proceeding and declined to decertify the collective proceeding. Based on the October 2016 arbitration ruling, the Company increased its accrual related to this matter. A damages trial is scheduled for April 2017. No trial date on the claimants' damages has been set by the arbitrator. The Company and the Central Parties dispute the arbitrator's rulings to date and intend to continue to vigorously defend against the plaintiffs' claims in both the collective action and individual proceedings. The likelihood that a loss has been incurred is probable.

Other Contingencies
Demand for Inspection of Books and Records
In February and Stockholder Derivative LawsuitDuring2016, the Company received several shareholder demands requesting to inspect the Company’sCompany's books and records, pursuant to Section 220 of the Delaware General Corporation Law.  The demands relate to the shareholders’shareholders' alleged investigation pertaining to whether the Board and Jerry Moyes have breached their fiduciary duties with respect to matters that have been publicly disclosed concerning the Company's securities trading policy, limitations on the pledging of Company stock on margin, share repurchases, the status of Board members as independent directors and share repurchases.other related matters. The Company ishas responded to the shareholders' requests received thus far. On February 9, 2016, a civil lawsuit was filed in the processCourt of respondingChancery of the State of Delaware (captioned as: Shiva Stein derivatively on behalf of Swift Transportation Company v. Jerry Moyes et al. and Swift Transportation Company as nominal defendant (the "Complaint")). The Complaint, initially filed as a confidential filing, is a purported derivative action alleging that the individual members of the Company's Board breached their fiduciary duties related to the shareholders’ requests.Company's administration of its Securities Trading Policy and certain compensation actions related to Mr. Moyes. Any future disposition or resolution of these matters cannot be determined at this time.
Environmental
The Company's tractors and trailers are involved in motor vehicle accidents, and experience damage, mechanical failures, and cargo issues as an incidental part of its normal ordinary course of operations.  From time to time, these matters result in the discharge of diesel fuel, motor oil, or other hazardous materials into the environment.  Depending on local regulations and who is determined to be at fault, the Company is sometimes responsible for the clean-up costs associated with these discharges.  As of December 31, 2015,2016, the Company's estimate for its total legal liability for all such clean-up and remediation costs was approximately $0.4$0.6 million in the aggregate for all current and prior year claims. 
 
Note 1618Derivative Financial Instruments

The Company has typically used pay-fixed/receive-variable interest rate swaps to reduce the Company’s aggregate exposure to interest rate risk. The Company does not enter into derivative agreements for speculative purposes.
Swift Interest Rate Swaps
In April 2011, as contemplated by the then-existing credit facility, the Company entered into two forward-starting interest rate swap agreements with a notional amount of $350.0 million. These interest rate swaps were effective in January 2013 and had a maturity date of July 2015. On April 27, 2011 ("designation date"), the Company designated and qualified these interest rate swaps as cash flow hedges. Subsequent to the designation date, the effective portion of the changes in estimated fair value of the designated swaps was recorded in AOCI, and thereafter reclassified to derivative interest expense in the periods that the interest on the hedged debt affected earnings. The Company began accruing for hedged interest in January 2013. Refer to Note 24 for amounts and the Company's methodology related to fair value of interest rate swaps.
On March 7, 2013, the Company entered into the 2013 Agreement, as discussed in Note 12. Due to the incorporation of a new interest rate floor provision in the 2013 Agreement, the Company concluded, as of February 28, 2013, that the outstanding interest rate swaps were no longer highly effective in achieving offsetting changes in cash flows related to the hedged interest payments. As a result, the Company de-designated the hedges as of February 28, 2013 ("de-designation date"), at which time the effective portion of the change in fair value of interest rate swaps (previously recorded in AOCI) was, and will continue to be, amortized as derivative interest expense over the period of the originally designated hedged interest payments through July 2015. Following the de-designation date, changes in fair value of the interest rate swaps are immediately recognized as derivative interest expense in the consolidated income statements.

Common Stock Transactions — Jerry Moyes and the Moyes Affiliates
Amended M Capital II VPF and Cactus VPFOn October 30, 2015, M Capital II and another Moyes Affiliate, Cactus Holding I, entered into the Amended M Capital II VPF and the Cactus VPF, respectively. The purposes of these two VPF contracts were to (i) extend the maturity date of M Capital II's then-existing VPF with Citibank N.A. entered into on October 29, 2013 and maturing on November 4, 2015 through November 6, 2015 and (ii) generate cash proceeds for the repayment of certain stock-secured obligations of Cactus Holding II, a Moyes Affiliate, and thereby effect the release of certain shares of Class B common stock pledged in connection with the same.
Cactus Holding I entered into the Cactus VPF contract in respect of 3.3 million shares of the Company's Class B common stock, which were pledged by Cactus Holding I as security for its obligations under the Cactus VPF contract. Under the Cactus VPF contract, Cactus Holding I was required to deliver to Citigroup Global Markets Inc. ("CGMI") a variable amount of stock or cash during a three trading day period at the maturity of the contract on November 21, 2016 through November 24, 2016 (later extended to November 25, 2016, then extended to 2017 as described below). In connection with the Cactus VPF contract, Cactus Holding I received $48.3 million from CGMI (including the $18.5 million noted in the paragraph below).
In connection with the Amended M Capital II VPF, M Capital II paid Citibank N.A. $18.5 million. The source of these funds was a cash payment from CGMI in connection with the Cactus VPF Contract. Under the Amended M Capital II VPF contract, M Capital II was required to deliver to Citibank N.A. a variable amount of stock or cash during a three trading day period at the maturity of the contract on November 21, 2016 through November 24, 2016 (later extended to November 25, 2016, then extended to 2017 as described below). The number of shares of the Company's Class B common stock subject to the Amended M Capital II VPF remained unchanged at 13.7 million.
On May 18, 2016, M Capital II terminated its VPF covering approximately 12.3 million shares of Class A common stock, and entered into a new VPF covering approximately 12.3 million shares of Class A common stock. The new VPF required M Capital II to deliver a variable amount of Class A common stock, up to a maximum of approximately 12.3 million shares, or an equivalent amount of cash, upon maturity dates occurring on May 26, 2017 through May 31, 2017. The new VPF is collateralized by approximately 12.3 million shares of Class B common stock.
Also on May 18, 2016, Cactus Holding I entered into a new VPF covering approximately 7.0 million shares of Class A common stock. The new VPF required Cactus Holding I to deliver a variable amount of Class A common stock, up to a maximum of approximately 7.0 million shares, or an equivalent amount of cash, upon maturity dates occurring on May 26, 2017 through May 31, 2017. The new VPF is collateralized by an aggregate of approximately 7.0 million shares of Class A common stock and Class B common stock which were previously pledged on margin.
On November 18, 2016, the maturity dates of the M Capital II VPFs were extended to December 5, 2017 through January 3, 2018, and the maturity dates of the Cactus Holding I VPFs were extended to December 5, 2017 through December 7, 2017. No additional shares were pledged in connection with these extensions.
The VPF contracts allow Mr. Moyes and the Moyes Affiliates to retain the same number of shares and voting percentage as they had prior to these VPF contracts. In addition, Mr. Moyes and the Moyes Affiliates are able to participate in price appreciation of the Company's common stock within certain levels.
In connection with the VPF transactions described above, an aggregate of approximately 34.3 million shares of Class B common stock and approximately 2.0 million shares of Class A common stock are collateralized to secure M Capital II's and Cactus Holding I's respective obligations under the VPF transactions.

Mr. Moyes’ counter party to the VPFs hedges their position by borrowing shares of Class A common stock and subsequently selling such shares, creating a short position. This hedging activity will fluctuate from time to time, based on the current market price of the Class A common stock and the counter party's strategy for reducing risk in their position. This hedging activity may place additional pressure on the price of the Class A common stock as such short positions are being put in place and/or may create a perception that the market is questioning Swift’s performance given the large short position that can occur and be reported. Maintaining this short position may offset some of the risk associated with a full share settlement of the VPF transactions as any shares received by the counter party might be used to settle these short positions thus reducing the amount that would otherwise be introduced to the market.
Cactus II Pledging — In July 2011 and December 2011, Cactus Holding Company II, LLC ("Cactus II"), an entity controlled by Mr. Moyes, pledged approximately 12.0 million shares of Class B common stock on margin as collateral for loan arrangements entered into by Cactus II and relating to Mr. Moyes. In connection with these December 2011 transactions, Cactus II converted approximately 6.6 million of the approximately 12.0 million pledged shares of Class B common stock into shares of Class A common stock on a one-for-one basis. During 2012, the Moyes Affiliates converted an additional approximately 1.1 million shares of Class B common stock to Class A common stock and sold approximately 4.8 million of these pledged Class A shares to a counter-party pursuant to a sale and repurchase agreement with a full recourse obligation to repurchase the securities at the same price on the fourth anniversary of sale.
This sale and repurchase agreement was replaced in May 2014 with a similar sale and repurchase agreement covering approximately 6.8 million shares. On May 18, 2016 the maturity of this agreement was extended to May 30, 2017, and was extended again on November 18, 2016 to November 30, 2017. On May 18, 2016, 2.0 million shares of Class A common stock and 5.1 million shares of Class B common stock previously pledged on margin for collateral for loan arrangements were transferred to a new VPF agreement as described above. On July 20, 2016, Cactus Holding II pledged an incremental approximately 1.9 million shares as collateral for a new loan arrangement. As of August 2, 2016, the Moyes Affiliates had pledged on margin a total of approximately 4.1 million shares, of which approximately 2.2 million were Class B and approximately 1.9 million were Class A common stock.
Other Obligations — On April 20, 2016, Mr. Moyes entered into a settlement agreement with the National Hockey League ("NHL") relating to a previously disclosed lawsuit between the NHL and Mr. Moyes. As part of the settlement agreement, certain of Mr. Moyes’ adult children entered into a Non-Recourse Guaranty and Pledge Agreement with the NHL pursuant to which they guaranteed certain obligations of Mr. Moyes and certain Moyes Affiliates to the NHL. The guarantor’s obligations are collateralized by 2.0 million shares of Class B common stock owned by the guarantors.
During 2016 and 2014, the Moyes Affiliates converted shares of common stock on a one-for-one basis as follows:

Compensatory Stock Plans
On March 28, 2014, the Board adopted the 2014 Stock Plan, which replaced the 2007 Stock Plan. The 2014 Stock Plan became effective upon stockholder approval on May 8, 2014, after which date no new awards would be granted under the 2007 Stock Plan. The 2007 Stock Plan continues to govern all awards granted under the 2007 Stock Plan until such awards have been exercised, forfeited, canceled, or have otherwise expired or terminated.
The 2014 Stock Plan generally contains the same features, terms and conditions as the 2007 Stock Plan. Additionally, the 2014 Stock Plan did not increase the number of shares of stock available for grant.grant, which means that the number of shares available for grant under the 2014 Stock Plan reflected the number of authorized but unissued (and not subject to outstanding awards) under the 2007 Stock Plan as of the date the 2014 Stock Plan became effective.
The 2014 Stock Plan permits the payment of cash incentive compensation and authorizes the granting of stock options, stock appreciation rights, restricted stock and RSUs, performance shares and performance share units, cash-based awards, and stock-based awards to the Company's employees and non-employee directors for up to 12.0 million shares of Class A common stock. As of December 31, 2015,2016, the aggregate number of shares remaining available under the 2014 Stock Plan was 4.94.3 million.

Stock Options
Stock options are the contingent right of award holders to purchase shares of Swift Transportation Company Class A common stock at a stated price for a limited time. For options granted prior to the Company's IPO in December 2010, theThe exercise price of options granted equaled or exceeded the estimated fair value of the common stock on the grant date. The estimated fair value of the common stock prior to the Company’s IPO in each case was determined by management based upon a number of factors, including the Company's discounted projected cash flows, comparative multiples of similar companies, the lack of liquidity of the Company's common stock and certain risks the Company faced at the time of the valuation. Options granted prior to the Company's IPO that had an exercise price that exceeded the IPO price of $11.00 were repriced to the IPO price at the time of the IPO. For options granted after the Company’s IPO, the exercise price of options granted equaledequals the fair value of the Company’sCompany's common stock determined by the closing price of the Company’sCompany's Class A common stock quoted on the NYSE on the grant date.
All options have a ten-year contractual term. The options issued prior to the Company's IPO were granted to two categories of employees. The options granted to the first category of employees vest upon the occurrence of the earliest of: (i) a sale or a change in control of the Company or, (ii) a five-year vesting period at a rate of 33 1/3% following the third anniversary date of the grant. The options granted to the second category of employees vest upon the later of (i) the occurrence of an initial public offering of the Company or (ii) a five-year vesting period at a rate of 33 1/3% following the third anniversary date of the grant. To the extent vested, both types of options become exercisable simultaneous with the closing of the earlier of (i) an initial public offering, (ii) a sale, or (iii) a change in control of the Company.

(1)The aggregate intrinsic value was computed using the closing share price on December 31, 2015 of $13.82 and on December 31, 2014 of $28.63, as applicable.
The fair value of each stock option grant is estimated on the grant date using the Black-Scholes-Merton option-pricing model, which uses a number of assumptions to determine the fair value of the options on the grant date. The following table presents the weighted average assumptions used to determine the fair value of stock options issued:

____________
(1)The dividend yield assumption is based on anticipated dividend payouts. The risk-free interest rate assumption is based on the United States Treasury yield curve at the grant date with maturity dates approximately equal to the expected life at the grant date. The Company estimates the expected volatility and expected option life assumption consistent with ASC Topic 718, Compensation – Stock Compensation. Expected volatility is based on anticipated dividend payouts.
(2)The risk-free interest rate assumption is based on the United States Treasury yield curve at the grant date with maturity dates approximately equal to the expected life at the grant date.
(3)
The Company estimates the expected volatility and expected option life assumption consistent with ASC Topic 718, Compensation – Stock Compensation. Beginning in 2016, we used our internal historical prices over the expected term of the options to determine our expected volatility. Prior to that, expected volatility was based upon an analysis of historical prices of similar market capitalized trucking group participants within the Dow Jones Total United States Market Index over the expected term of the options. The Company chose a daily measurement interval for historical volatility as it believes this better depicts the nature of employee option exercise decisions being based on shorter-term trends in the price of the underlying shares, rather than on monthly price movements. As a result of the inability to predict the expected future employee exercise behavior, the Company estimated the expected term of the options using a simplified method based on contractual and vesting terms of the options. The Company uses historical data to estimate pre-vesting option forfeitures and records stock-based compensation expense only for those awards that are expected to vest.

Valuation Allowance — As of December 31, 2015, the Company had federal and state net operating loss carryforwards remaining, with estimated tax effects of $0.4 million and $0.6 million, respectively. The federal and state net operating losses will expire at various times between 2016 and 2030. The Company has not established a valuation allowance as it has been determined that, based upon available evidence, a valuation allowance is not required. Management asserts that it is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax assets. All other deferred tax assets are expected to be realized and utilized by continued profitability in future periods.
Cumulative Undistributed Foreign Earnings — United States income and foreign withholding taxes have not been provided on approximately $25.3 million of cumulative undistributed earnings of foreign subsidiaries. The earnings are considered to be permanently reinvested outside the United States. As such, the Company is not required to provide United States income taxes on these earnings until they are repatriated in the form of dividends or otherwise.
Unrecognized Tax Benefits — The Company's unrecognized tax benefits as of December 31, 2015 would favorably impact our effective tax rate if subsequently recognized. The following is a rollforward of our unrecognized tax benefits (in thousands):

Tax Examinations — During the year ended December 31, 2014, the Company concluded its California examination, as well as various other state examinations for certain of its subsidiaries. The conclusion of these examinations resulted in $0.8 million of additional tax payments and $0.4 million of interest and penalties during 2014. Additional tax payments, as well as interest and penalties related to various state and federal tax examinations concluded during the years ended December 31, 2015 and 2013 were immaterial. Other state jurisdictions are currently conducting examinations for years ranging from 2011 to 2013. At the completion of these examinations, management does not expect any adjustments that would have a material impact on the Company’s effective tax rate. Years subsequent to 2011 remain subject to examination.

Interest and Penalties — The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits as a component of income tax expense. Accrued interest and penalties as of December 31, 2015, 2014 and 2013, were approximately $1.4 million, $1.3 million and $1.5 million, respectively. To the extent interest and penalties are not assessed with respect to uncertain tax positions, amounts accrued will be reduced and reflected as a reduction of the overall income tax provision.
Regulatory Developments In December 2014, United States President, Barack Obama, signed the TIPA Act. Among other things, TIPA extended 50% bonus depreciation and the WOTC. During the first three quarters of 2014, the Company did not include 50% bonus depreciation or WOTC in its income tax provision, as these items were not allowed under the previous tax code. Income tax calculations performed for the year ended December 31, 2014 included the full year's adjustment for 50% bonus depreciation and WOTC, as TIPA allowed for retrospective inclusion.
In December 2015, President Obama signed the PATH Act of 2015. Among other things, PATH extended 50% bonus depreciation and WOTC. During the first three quarters of 2015, the Company did not include 50% bonus depreciation or WOTC in its income tax provision, as these items were not allowed under the previous tax regime. Income tax calculations performed for the year ended December 31, 2015 include the full year's adjustment for 50% bonus depreciation and WOTC, as PATH allowed for retrospective inclusion.
 
Note 21 — Employee Benefits
The Company maintains a 401(k) benefit plan available to all employees who are 21 years of age or older and have completed six months of service. Under the plan, the Company has the option to match employee discretionary contributions up to 3% of an employee’s compensation.

Note 24 — Fair Value Measurement
ASC Topic 820, Fair Value Measurements and Disclosures, requires that the Company disclose estimated fair values for its financial instruments. The estimated fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in the principal or most advantageous market for the asset or liability. Fair value estimates are made at a specific point in time and are based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’sCompany's entire holdings of a particular financial instrument. Changes in assumptions could significantly affect these estimates. Because the fair value is estimated as of December 31, 20152016 and 2014,2015, the amounts that will actually be realized or paid at settlement or maturity of the instruments in the future could be significantly different.
The tables below exclude certain financial instruments. The excluded financial instruments are as follows: cash and cash equivalents, restricted cash, net accounts receivable, income tax refund receivable, and accounts payable. The estimated fair value of these financial instruments approximate carrying value as they are short-term in nature. Additionally, for notes payable under revolving lines of credit, fair value approximates the carrying value due to the variable interest rate. For capital leases, the carrying value approximates the fair value. The table below also excludes financial instruments reported at estimated fair value on a recurring basis. See "Recurring Fair Value Measurements." All remaining balance sheet amounts excluded from the table below are not considered financial instruments subject to this disclosure.

The estimated fair values of the financial instruments shown in the above table as of December 31, 2016 and 2015, and 2014, represent management’smanagement's best estimates of the amounts that would be received to sell those assets or that would be paid to transfer those liabilities in an orderly transaction between market participants at that date. The estimated fair value measurements maximize the use of observable inputs. However, in situations where there is little, if any, market activity for the asset or liability at the measurement

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED

date, the estimated fair value measurement reflects the Company’sCompany's own judgments about the assumptions that market participants would use in pricing the asset or liability. These judgments are developed by the Company based on the best information available under the circumstances.
The following summary presents a description of the methods and assumptions used to estimate the fair value of each class of financial instrument.
Restricted Investments — The estimated fair value of the Company’sCompany's restricted investments is based on quoted prices in active markets that are readily and regularly obtainable.
Term Loans — The estimated fair value of the Term Loan B was determined by bid prices in trades between qualified institutional buyers.A approximates the face value.

Securitization of Accounts Receivable — The Company’sCompany's securitization of accounts receivable consists of borrowings outstanding pursuant to the Company’sCompany's 2015 RSA and 2013 RSA as of December 31, 20152016 and 2014, respectively,2015, as discussed in Note 11.12. Its fair value is estimated by discounting future cash flows using a discount rate commensurate with the uncertainty involved.
Derivative Financial Instruments —As of December 31, 2014, interest rate swaps represent the only major category of assets or liabilities included in the consolidated balance sheets that are measured by estimating fair value on a recurring basis. The fair values of the interest rate swaps was based on valuations provided by third parties, derivative pricing models, and credit spreads derived from the trading levels of the Company’s first lien term loan as of December 31, 2014. The Company’s interest rate swaps were not actively traded, but are valued using valuation models and credit valuation adjustments, both of which used significant inputs that were observable in active markets over the terms of the instruments the Company held, and accordingly, the Company classified these valuation techniques as Level 2 in the hierarchy. Interest rate yield curves and credit spreads derived from trading levels of the Company’s first lien term loan were the significant inputs into these valuation models. These inputs were observable in active markets over the terms of the instruments the Company held. The Company considered the effect of its own credit standing and that of its counterparties in the valuations of its derivative financial instruments.
Fair Value Hierarchy — ASC Topic 820 establishes a framework for measuring fair value in accordance with US-GAAP and expands financial statement disclosure requirements for fair value measurements. ASC Topic 820 further specifies a hierarchy of valuation techniques, which is based on whether the inputs into the valuation technique are observable or unobservable. The hierarchy is as follows:
Level 1 — Valuation techniques in which all significant inputs are quoted prices from active markets for assets or liabilities that are identical to the assets or liabilities being measured.
Level 2 — Valuation techniques in which significant inputs include quoted prices from active markets for assets or liabilities that are similar to the assets or liabilities being measured and/or quoted prices from markets that are not active for assets or liabilities that are identical or similar to the assets or liabilities being measured. Also, model-derived valuations in which all significant inputs and significant value drivers are observable in active markets are Level 2 valuation techniques.
Level 3 Valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are valuation technique inputs that reflect the Company’sCompany's own assumptions about the assumptions that market participants would use in pricing an asset or liability.

111



SWIFT TRANSPORTATION COMPANY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED

When available, the Company uses quoted market prices to determine the estimated fair value of an asset or liability. If quoted market prices are not available, the Company measures fair value using valuation techniques that use, when possible, current market-based or independently-sourced market parameters, such as interest rates and currency rates. The level in the fair value hierarchy within which a fair value measurement in its entirety falls is based on the lowest level input that is significant to the estimated fair value measurement in its entirety.

Recurring Fair Value Measurements — As of December 31, 2016 and 2015, no major categories of assets or liabilities included in the Company's consolidated balance sheets at estimated fair value were measured on a recurring basis.
Nonrecurring Fair Value Measurements — As of December 31, 2016 and 2015 there were no liabilities included in the Company's consolidated balance sheets at estimated fair value that were measured on a nonrecurring basis.

(1)During the three months ended December 31, 2016, certain operations software related to the Company's logistics business was determined to be fully impaired based on a significant decrease in the expected useful life of the software. This resulted in a pre-tax impairment loss of $0.5 million, which was recorded in "Impairments" within operating income in the consolidated income statement.
(2)During the three months ended December 31, 2016, management reassessed the fair value of certain IEL tractors, which had a total book value of $2.2 million, determining that there was a pre-tax impairment loss of $0.3 million. The impairment loss was recorded in "Impairments" within operating income in the consolidated income statement.

(3)In September 2013, the Company agreed to advance up to $2.3 million, pursuant to an unsecured promissory note, to an independent fleet contractor that transported freight on Swift's behalf. In March 2015, management became aware that the independent contractor violated various covenants outlined in the unsecured promissory note, which created an event of default that made the principal and accrued interest immediately due and payable. As a result of this event of default, as well as an overall decline in the independent contractor's financial condition, management re-evaluated the fair value of the unsecured promissory note. At March 31, 2015, management determined that the remaining balance due from the independent contractor to the Company was not collectible, which resulted in a $1.5 million pre-tax adjustment that was recorded in "Non-cash impairments of non-operating assets" in the Company's consolidated income statements.

Note 23 — Jerry Moyes' Retirement
In conjunction with the Company's September 8, 2016 announcement that Jerry Moyes would retire from his position as Chief Executive Officer effective December 31, 2016, the Company entered into an agreement with Mr. Moyes to memorialize the terms of his retirement. The Company contracted with Mr. Moyes to serve as a non-employee consultant from January 1, 2017 through December 31, 2019, during which time the Company will pay Mr. Moyes a monthly consulting fee of $0.2 million in cash. Additionally, the Company modified the vesting terms and forfeiture conditions of Mr. Moyes' previously-granted equity awards. As a result of the terms of the agreement, the Company incurred a one-time expense in September 2016 of $7.1 million, consisting of $6.8 million in accrued consulting fees and $0.3 million for the impact of the equity award modifications. The amounts are included in "Salaries, wages, and employee benefits" within the non-reportable segments' income statement.
The following is a rollforward of the accrued liability for the consulting fees:

The $0.3 million impact of the equity award modification is excluded from the accrual balance because it is classified as "Additional paid-in capital" in the consolidated balance sheet.
Note 24 — Information by Segment, Geography, and Customer Concentration
Segment Information
During 2015,2016, we operated four reportable segments: Truckload, Dedicated, Swift Refrigerated, (formerly Central Refrigerated) and Intermodal.
Truckload The truckload segment consists of one-way movements over irregular routes throughout the United States, Mexico, and Canada. This service utilizes both company and owner-operator tractors with dry van, flatbed, and other specialized trailing equipment.
DedicatedThrough the dedicated segment, the Company devotes use of equipment to specific customers and offers tailored solutions under long-term contracts. This dedicated segment utilizes refrigerated, dry van, flatbed, and other specialized trailing equipment.
Swift RefrigeratedThis segment primarily consists of shipments for customers that require temperature-controlled trailers. These shipments include one-way movements over irregular routes, as well as dedicated truck operations.

Non-reportable SegmentSegments The other non-reportable segment includessegments include the Company's logistics and freight brokerage services, as well as support services provided bythat its subsidiaries provide to customers and owner-operators, including repair and maintenance shop services, equipment leasing, and insurance. Intangible asset amortization related to the 2007 Transactions, iscertain legal settlements and reserves, and certain other corporate expenses are also included in thisthe other non-reportable segment.segments.
Intersegment Eliminations Certain operating segments provide transportation and related services for other affiliates outside their reportable segment. Revenues for such services are based on negotiated rates, which we believe approximate fair value, and are reflected as revenues of the billing segment. These rates are adjusted from time to time based on market conditions. Such intersegment revenues and expenses are eliminated in our consolidated results.

ITEM 9A.CONTROLS AND PROCEDURES
Disclosure Controls and Procedures
As of the end of the period covered by this annual report on Form 10-K, we carried out an evaluation, under the supervision and with the participation of our management, including our CEO and CFO, of the effectiveness of our disclosure controls and procedures as such term is defined in Exchange Act Rules 13a-15(e) and 15d-15(e), including controls and procedures to timely alert management to material information relating to Swift Transportation Company and subsidiaries required to be included in our periodic SEC filings. Based on that evaluation, our CEO and CFO have concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report.
Changes in Internal Control over Financial Reporting
There has been no significant change in our internal control over financial reporting during the quarter ended December 31, 20152016 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
Management’sManagement's Report on Internal Control over Financial Reporting
Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. The Company's internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States. Internal control over financial reporting includes policies and procedures that:
(i)pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the Company’sCompany's assets;
(ii)provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States,accounting principles, and that receipts and expenditures are being made only in accordance with the authorization of management and directors of the Company; and
(iii)provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’sCompany's assets that could have a material effect on the financial statements.
Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.
Under the supervision and with the participation of our CEO and CFO, management conducted an evaluation of the Company's internal control over financial reporting as of December 31, 2015.2016.  In making this evaluation, management used the criteria in Internal Control – Integrated Framework, issued in 2013 by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO").  Based on this assessment, management concluded that its internal control over financial reporting was effective as of December 31, 2015.2016.
The effectiveness of internal control over financial reporting as of December 31, 20152016 was audited by KPMG LLP, the independent registered public accounting firm that also audited the Company's consolidated financial statements included in this Annual Report on Form 10-K.  KPMG LLP’sLLP's report on the Company's internal control over financial reporting is included herein.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders
Swift Transportation Company:
We have audited Swift Transportation Company and subsidiaries’ (the Company) internal control over financial reporting as of December 31, 2015,2016, based on criteria established inInternal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying “Management’s Report on Internal Control over Financial Reporting” appearing under Item 9A. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
In our opinion, theSwift Transportation Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015,2016, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Swift Transportation Company and subsidiaries as of December 31, 20152016 and 2014,2015, and the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2015,2016, and our report dated February 22, 201617, 2017 expressed an unqualified opinion on those consolidated financial statements.

On March 28, 2014, the Board adopted the Swift Transportation Company 2014 Omnibus Incentive Plan ("2014 Stock Plan,") which replaced the Swift Transportation Company 2007 Omnibus Incentive Plan ("2007 Stock Plan").Plan. The 2014 Stock Plan became effective on May 8, 2014, upon approval by the Company's stockholders. After May 8, 2014, no new awards were granted under the 2007 Stock Plan.

The 2014 Stock Plan generally contains the same features, terms, and conditions as the 2007 Stock Plan. Additionally, the 2014 Stock Plan did not increase the number of shares of stock available for grant, which means that the number of shares available for grant under the 2014 Stock Plan reflected the number of authorized but unissued (and not subject to outstanding awards) under the 2007 Stock Plan as of the date the 2014 Stock Plan became effective. The material features of the Company's 2014 Stock Plan, as well as the 2012 ESPP, are described in Note 19 to the consolidated financial statements contained in this Form 10-K.
