PART I

Item 1. Business.

Unless the context otherwise requires, all references in this Annual Report on Form 10-K to “P.A.M.,” the “Company,” “we,” “our,” or “us” mean P.A.M. Transportation Services, Inc. and its subsidiaries.

We are a truckload dry van carrier transporting general commodities throughout the continental United States, as well as in certain Canadian provinces. We also provide transportation services in Mexico under agreements with Mexican carriers. Our freight consists primarily of automotive parts, expedited goods, consumer goods, such as general retail store merchandise, and manufactured goods, such as heating and air conditioning units.

P.A.M. Transportation Services, Inc. is a holding company incorporated under the laws of the State of Delaware in June 1986. We conduct operations through the following wholly owned subsidiaries: P.A.M. Transport, Inc., T.T.X., LLC, P.A.M. Cartage Carriers, LLC, Overdrive Leasing, LLC, P.A.M. Logistics Services, Inc., Choctaw Express, LLC, Choctaw Brokerage, Inc., Transcend Logistics, Inc., Decker Transport Co., LLC, East Coast Transport and Logistics, LLC, S & L Logistics, Inc., P.A.M. International, Inc. and P.A.M. Canada, Inc. Our operating authorities are held by P.A.M. Transport, Inc., P.A.M. Cartage Carriers, LLC, Choctaw Express, LLC, Choctaw Brokerage, Inc., T.T.X., LLC, Decker Transport Co., LLC, and East Coast Transport and Logistics, LLC. Effective on January 1, 2010, the operations of most of the Company’s operating subsidiaries were consolidated under the P.A.M. Transport, Inc. name in an effort to more clearly reflect the Company’s scope and available service offerings. Effective September 30, 2010, the Company sold the assets of East Coast Transport and Logistics, LLC which effectively closed the Company’s New Jersey based brokerage office.

We are headquartered and maintain our primary terminal and maintenance facilities and our corporate and administrative offices in Tontitown, Arkansas, which is located in northwest Arkansas, a major center for the trucking industry and where the support services (including warranty repair services) for most major truck and trailer equipment manufacturers are readily available.

In order to conform to industry practice, the Company began to classify payments to third-party owner operator drivers as purchased transportation rather than as salaries, wages and benefits as had been presented in reports prior to the period ended September 30, 2013. This reclassification has no effect on operating income, net income or earnings per share. The Company has made corresponding reclassifications to comparative periods shown.

Segment Financial Information

The Company's operations are all in the motor carrier segment and are aggregated into a single reporting segment in accordance with the aggregation criteria under Generally Accepted Accounting Principles (“GAAP”).

Operations

Our operations can generally be classified into truckload services or brokerage and logistics services. Truckload services include those transportation services in which we utilize company owned trucks or owner-operator owned trucks for the pickup and delivery of freight. The brokerage and logistics services consists of services such as transportation scheduling, routing, mode selection, transloading and other value added services related to the transportation of freight which may or may not involve the use of company owned or owner-operator owned equipment. Both our truckload operations and our brokerage and logistics operations have similar economic characteristics and are impacted by virtually the same economic factors as discussed elsewhere in this Report. Truckload services operating revenues, before fuel surcharges represented 92.6%, 91.8% and 93.5% of total operating revenues for the years ended December 31, 2013, 2012 and 2011, respectively. The remaining operating revenues, before fuel surcharge for the same periods were generated by brokerage and logistics services, representing 7.4%, 8.2%, and 6.5%, respectively.

- 1 -

Approximately 55% of the Company's revenues are derived from domestic shipments while approximately 45% of our revenues are derived from freight originating from or destined to locations in Mexico or Canada.

Business and Growth Strategy

Our strategy focuses on the following elements:

Providing a Full Suite of Complimentary Truckload Transportation Solutions. Our objective is to provide our customers with a comprehensive solution to their truckload transportation needs. Our asset-based service offerings consist of dedicated, expedited, regional, automotive, and long-haul truckload services with non-asset based supply chain management, logistics and brokerage solutions rounding out our service offerings. Our range of service offerings also include our complete range of asset-based and non-asset based services to Mexico and Canada.

Developing Customer Relationships within High Density Traffic Lanes. We strive to maximize utilization and increase revenue per truck while minimizing our time and empty miles between loads. In this regard, we seek to provide equipment to our customers in defined regions and disciplined traffic lanes. This strategy enables us to:

· maintain more consistent equipment capacity;

· provide a high level of service to our customers, including time-sensitive delivery schedules;

· attract and retain drivers; and

· maintain a sound safety record as drivers travel familiar routes.

Providing Superior and Flexible Customer Service. Our wide range of services includes expedited services, dedicated fleet services, logistics services, time-definite delivery, two-person driving teams, cross-docking and consolidation programs, specialized trailers, international services to Mexico and Canada, and Internet-based customer access to delivery status. These services allow us to quickly and reliably respond to the diverse needs of our customers, and provide an advantage in securing new business.

Many of our customers depend on us to make delivery on a time-definite basis, meaning that parts or raw materials are scheduled for delivery as they are needed on a manufacturer’s production line. The need for this service is a product of modern manufacturing and assembly methods that are designed to decrease inventory levels and handling costs. Such requirements place a premium on the freight carrier’s delivery performance and reliability.

Employing Stringent Cost Controls. Throughout our organization, emphasis is placed on gaining efficiency in our processes with the primary goals of decreasing costs and improving customer satisfaction. Maintaining a high level of efficiency and prioritizing our focus on improvements allows us to minimize the number of non-driving personnel we employ and positively influence other overhead costs. Expenses are intensely scrutinized for opportunities for elimination, reduction or to further leverage our purchasing power to achieve more favorable pricing.

Industry

According to the American Trucking Association’s “American Trucking Trends 2013” report, the trucking industry transported approximately 68.5% of the total volume of freight transported in the United States during 2012, which equates to 9.4 billion tons and approximately $642 billion in revenue. The truckload industry is highly fragmented and is impacted by several economic and business factors, many of which are beyond the control of individual carriers. The state of the economy, coupled with equipment capacity levels, can impact freight rates. Volatility of various operating expenses, such as fuel and insurance, make the predictability of profit levels uncertain. Availability, attraction, retention and compensation of drivers also affect operating costs, as well as equipment utilization. In addition, the capital requirements for equipment, coupled with potential uncertainty of used equipment values, impact the ability of many carriers to expand their operations. The current operating environment is characterized by the following:

· Intense competition for freight;

· Price increases by truck and trailer equipment manufacturers;

· Volatile fuel costs, generally trending higher, and

· In recent years, many less profitable or undercapitalized carriers have been forced to consolidate or to exit the industry.

Competition

The trucking industry is highly competitive and includes thousands of carriers, none of which dominates the market in which the Company operates. The Company's market share is less than 1% and we compete primarily with other irregular route medium- to long-haul truckload carriers, with private carriage conducted by our existing and potential customers, and, to a lesser extent, with the railroads. We compete on the basis of quality of service and delivery performance, as well as price. Many of the other irregular route long-haul truckload carriers have substantially greater financial resources, own more equipment or carry a larger total volume of freight as compared to the Company.

Marketing and Significant Customers

Our marketing emphasis is directed to that portion of the truckload market which is generally service-sensitive, as opposed to being solely price competitive. We seek to become a “core carrier” for our customers in order to maintain high utilization and capitalize on recurring revenue opportunities. Our marketing efforts are diversified and designed to gain access to dedicated, expedited, regional, automotive, and long-haul opportunities (including those in Mexico and Canada) and to expand supply chain solutions offerings.

Our marketing efforts are conducted by a sales staff of nine employees who are located in our major markets and supervised from our headquarters. These individuals work to improve profitability by maintaining an even flow of freight traffic (taking into account the balance between originations and destinations in a given geographical area), high utilization, and minimizing movement of empty equipment.

Our five largest customers, for which we provide carrier services covering a number of geographic locations, accounted for approximately 43%, 39% and 47% of our total revenues in 2013, 2012 and 2011, respectively. General Motors Corporation accounted for approximately 21%, 17% and 26% of our revenues in 2013, 2012 and 2011, respectively. Another large customer, Chrysler, accounted for approximately 12%, 12% and 5% of our revenues in 2013, 2012 and 2011, respectively.

- 3 -

We also provide transportation services to other manufacturers who are suppliers for automobile manufacturers. Approximately 46%, 37% and 38% of our revenues were derived from transportation services provided to the automobile industry during 2013, 2012 and 2011, respectively.

Revenue Equipment

At December 31, 2013, we operated a fleet of 1,837 trucks, which includes 357 owner-operator trucks, and 5,170 trailers, which includes 91 leased trailers. Our company-owned trucks are late model, well-maintained, premium trucks, which we believe help to attract and retain drivers, maximize fuel efficiency, promote safe operations, minimize maintenance and repair costs, and improve customer service by minimizing service interruptions caused by breakdowns. We evaluate our equipment purchasing decisions based on factors such as initial cost, useful life, warranty terms, expected maintenance costs, fuel economy, driver comfort, customer needs, manufacturer support, and resale value.

We contract with owner-operators to provide greater flexibility in responding to fluctuations in consumer demand. Owner-operators provide their own trucks and are contractually responsible for all associated expenses, including financing costs, fuel, maintenance, insurance, and taxes, among other things. They are also responsible for maintaining compliance with the Federal Motor Carrier Safety Administration regulations.

During 1999, the U.S. Environmental Protection Agency (“EPA”) mandated a three-phase strategy to reduce engine emissions from heavy-duty vehicles through a combination of advanced emissions control technologies and diesel fuel with a reduced sulfur content. The first phase (Phase I) mandated new engine emission standards for all model year 2004 heavy-duty trucks; however, through agreements with heavy-duty diesel engine manufacturers, the effective date was accelerated to October 1, 2002. Since October 1, 2002, all newly manufactured truck engines had to comply with the new engine emission standards. As of December 31, 2013, the Company-owned truck fleet does not contain any trucks with the older Phase I engines.

In the second phase (Phase II), effective January 1, 2007, the EPA mandated a new set of more stringent emission standards for vehicles powered by diesel fuel engines manufactured in 2007 through 2009. As of December 31, 2013, our Company-owned truck fleet consisted of fewer than 20 trucks with engines that comply with the Phase II emission standards (Phase II trucks) and are either leased to third parties or are in process of being sold. As compared to trucks powered by the Phase I engines, the trucks powered by the Phase II compliant diesel engines had a significantly higher purchase price and as a result, our depreciation expense increased over time as we replaced Phase I trucks with Phase II trucks.

During the third phase (Phase III), which was effective in 2010, final emission standards became effective. During 2013, the Company took delivery of approximately 550 trucks, all of which contained engines compliant with the Phase III emission standards. As of December 31, 2013, substantially all of our Company-owned truck fleet consisted of trucks with engines that comply with the Phase III emission standards (Phase III trucks). During 2014, the Company expects to take delivery of 300 additional Phase III trucks. To date, the Company-owned Phase III trucks have shown increased fuel efficiency as compared to either the Phase I or Phase II truck fuel efficiency, however, Phase III trucks have a significant purchase price premium as compared to the purchase price of the Phase I and Phase II trucks and as a result, our depreciation expense per truck has increased. We expect that the costs to replace older trucks will continue to increase due to both an increase in new truck purchase prices and in maintenance costs as the engines become more complex to meet future EPA regulations. To the extent we are unable to offset these anticipated increased costs with rate increases charged to customers or offsetting cost savings in other areas, our results of operations will be adversely affected.

Technology

We have installed Qualcomm display units in all of our trucks. The Qualcomm system is a satellite-based global positioning and communications system that allows fleet managers to communicate directly with drivers. Drivers can provide location, status and updates directly to our computer system which increases productivity and convenience. This system provides us with accurate estimated time of arrival information, which optimizes load selection and service levels to our customers.

Our information systems manage the data provided by the Qualcomm devices to provide us with real-time information regarding the location, status and load assignment of our trucks, which permits us to better meet delivery schedules, respond to customer inquiries and match equipment with the next available load. Our system also provides real-time information electronically to our customers regarding the status of freight shipments and anticipated arrival times. This system provides our customers flexibility and convenience by extending supply chain visibility through electronic data interchange, the Internet and e-mail.

Maintenance

We have a strictly enforced comprehensive preventive maintenance program for our trucks and trailers. Inspections and various levels of preventive maintenance are performed at set intervals on both trucks and trailers. A maintenance and safety inspection is performed on all vehicles each time they return to a terminal.

Our trucks carry full warranty coverage for at least three years or 375,000 miles. Extended truck warranties can be negotiated with the truck manufacturer and manufacturers of major components, such as engine, transmission and differential manufacturers, for up to four years or 500,000 miles. Our trailers carry full warranties by the manufacturer for up to 5 years with certain components covered for up to ten years.

Employees

At December 31, 2013, we employed 3,034 persons, of whom 2,477 were drivers, 185 were employed in maintenance, 171 were employed in operations, 38 were employed in marketing, 95 were employed in safety and personnel, and 68 were employed in general administration and accounting. None of our employees is represented by a collective bargaining unit and we believe that our employee relations are good.

Drivers

At December 31, 2013, we utilized 2,477 company drivers in our operations. We also had 357 owner-operators under contract compensated on a per mile basis. Our drivers are compensated on the basis of miles driven, loading and unloading, extra stops, and layovers in transit. Drivers can earn bonuses by recruiting other qualified drivers who become employed by us and both cash and non-cash prizes are awarded for achieving certain miles per gallon goals. All of our drivers are recruited, screened, drug tested and participate in our driver training program. Our driver training program stresses the importance of safety and reliable, on-time delivery. Drivers are required to report to their driver managers daily and at the earliest possible moment when any condition en route occurs that might delay their scheduled delivery time.

Owner-operators are utilized through a contact with us to supply one or more tractors and drivers for our use. Owner-operators must pay their own tractor expenses, fuel, maintenance, insurance, and driver costs. They must meet and operate within our guidelines with respect to safety. We have a lease-purchase program whereby we offer owner-operators the opportunity to lease a tractor, with the option to purchase the tractor at the end of the lease term. We believe our lease-purchase program has contributed to our ability to attract and retain owner operators. At December 31, 2013, approximately 40 owner-operators were participating in this program.

- 5 -

In addition to strict application screening and drug testing, before being permitted to operate a vehicle, our drivers must undergo classroom instruction on our policies and procedures, safety techniques as taught by the Smith System of Defensive Driving, and the proper operation of equipment, and must pass both written and road tests. Instruction in defensive driving and safety techniques continues after hiring, with seminars at several of our terminals. At December 31, 2013, we employed 77 persons on a full-time basis in our driver recruiting, training and safety instruction programs.

Intense competition in the trucking industry for qualified drivers has resulted in additional expense to recruit and retain an adequate supply of drivers, and has had a negative impact on the industry. Our operations have also been impacted and from time to time we have experienced under-utilization and increased expenses due to a shortage of qualified drivers. We place a high priority on the recruitment and retention of an adequate supply of qualified drivers.

Available Information

The Company maintains a website where additional information concerning its business can be found. The address of that website is www.pamtransport.com. The Company makes available free of charge on its Internet website its Annual Report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (the “Exchange Act”) as soon as reasonably practicable after it electronically files or furnishes such materials to the Securities and Exchange Commission.

Seasonality

Our revenues do not exhibit a significant seasonal pattern due primarily to our varied customer mix. Operating expenses can be somewhat higher in the winter months primarily due to decreased fuel efficiency and increased maintenance costs associated with inclement weather. In addition, the automobile plants for which we transport a large amount of freight typically utilize scheduled shutdowns in July and December and the volume of automotive freight we ship is reduced during such scheduled plant shutdowns.

Regulation

We are a common and contract motor carrier regulated by various United States federal and state, Canadian provincial, and Mexican federal agencies. These regulatory agencies have broad powers, generally governing matters such as authority to engage in motor carrier operations, motor carrier registration, driver hours-of-service (“HOS”), drug and alcohol testing of drivers, and safety, size, and weight of transportation equipment. The primary regulatory agencies affecting the Company’s operations include the Federal Motor Carrier Safety Administration (“FMCSA”), the Pipeline and Hazardous Materials Safety Agency, and the Surface Transportation Board, which are all agencies within the U.S. Department of Transportation (“DOT”). We believe that we are in compliance in all material respects with applicable regulatory requirements relating to our business and operate with a “satisfactory” rating (the highest of three rating categories) from the DOT. In addition, we are subject to compliance with cargo-security and transportation regulations issued by the Transportation Security Administration, a component department within the U.S. Department of Homeland Security. To the extent that we conduct operations outside the United States, we are subject to the Foreign Corrupt Practices Act, which generally prohibits U.S. companies and their intermediaries from offering bribes to foreign officials for the purpose of obtaining or retaining favorable treatment.

In 2004, the FMCSA issued updated rules related to driver HOS limits that became effective October 1, 2005 (the "2005 Rules"). In July 2007, a federal appeals court vacated certain provisions of the 2005 Rules relating to the expansion of the daily driving limit from 10 hours to 11 hours, and the "34-hour restart," which allowed drivers to restart calculations of the weekly on-duty time limits after the driver had at least 34 consecutive hours off duty. The court indicated that, in addition to other reasons, it vacated these two provisions because the FMCSA failed to provide adequate data supporting its decision to increase the daily driving limit and provide for the 34-hour restart provision. In November 2008, following the submission of additional data by FMCSA and a series of appeals and related court rulings, the FMCSA published its final rule, which retained the 11 hour daily driving limit and the 34-hour restart provision. Safety advocacy groups continued to challenge the final rule and in an effort to end litigation by these groups, the FMCSA agreed to propose new rules by July 26, 2011. During December 2010, the FMCSA released the proposed new rules for public comment which included provisions that would shorten allowable daily driving time from 11 hours to 10 hours and also require that drivers take two nights of rest during the 34-hour restart provision. The proposed rules, which were generally not well received by either safety advocacy groups or by the trucking industry, were finalized and published by the FMCSA in December 2011. The final rule, effective July 1, 2013, retained the 11 hour daily driving limit but restricted the use of the 34-hour restart provision to once every seven days and the 34-hour period must include two periods between 1:00 a.m. and 5:00 a.m. and requires drivers to take a 30-minute off duty break after driving 8 hours. During 2012, both the American Trucking Association and safety advocacy groups had filed petitions with the D.C. U.S. Circuit Court of Appeals requesting the court to review the FMCSA’s final rule. Oral arguments began on March 15, 2013 and a final ruling was issued August 2, 2013. The final ruling upheld the HOS rules effective July 1, 2013 with the exception of vacating the 30-minute off duty break for short haul truck drivers. Although the final HOS rules have made an impact on the utilization of our equipment and our drivers’ productivity, they have not had a significant negative impact on our operations.

During February 2012, the FMCSA announced its intent to continue to pursue a rule that would require all interstate motor carriers to install electronic on-board recorders (“EOBRs”) to monitor compliance with HOS regulations. The FMCSA’s previous efforts in 2011 to implement a rule requiring EOBRs were successfully challenged in court and the rule was vacated in August 2011 as the court ruled that the FMCSA failed to directly address the potential for harassment of vehicle operators. The vacated rule applied to phase one of a two-phase rule implementation process whereby implementation of phase one would require EOBR use only by habitual HOS regulation violators while phase two would require EOBR use by all motor carriers. The FMCSA refers to these two-phases as EOBR 1 and EOBR 2, respectively. Under EOBR 1, any motor carrier found to have a HOS regulation violation rate of 10% or greater would be required to install EOBRs on all of its commercial motor vehicles for a period of two years. The final rule related to EOBR 1 was published in April 2010 and, prior to being vacated, was to be effective for any single compliance review completed on or after June 4, 2012. Under EOBR 2, all motor carriers required to maintain HOS record keeping would be required to use EOBRs to monitor their drivers' compliance with HOS requirements. Motor carriers would have three years after the effective date of the EOBR 2 final rule to comply with these requirements. As of December 31, 2013, the Company is not subject to any requirement that EOBRs be installed on any of its trucks, however all the Company’s trucks currently have EOBRs installed.

During 2010, the FMCSA also implemented its “Compliance, Safety, Accountability” program (“CSA”), formerly known as “Comprehensive Safety Analysis 2010” or “CSA 2010”. The stated goal under CSA is to achieve a greater reduction in large truck and bus crashes, injuries and fatalities, while maximizing the resources of the FMCSA and its state partners. Since the 1970s, federal and state enforcement agencies, in partnership with the motor carrier industry, have progressively reduced the commercial vehicle related fatality crash rate. Under CSA, the FMCSA uses a comprehensive measurement system of all safety-based violations found during roadside inspections, weighing such violations by their relationship to crash risk. CSA data analysis expands on the previous system utilized by the FMCSA and covers more behavioral areas specifically linked to crash risk such as unsafe or fatigued driving, driver fitness, controlled substances, crash history, vehicle maintenance, and improper loading. Safety performance information is accumulated to assess the safety performance of both carriers and drivers. This expanded methodology for determining a carrier's DOT safety rating may have an adverse effect on our DOT safety rating. We currently have a satisfactory DOT rating, which is the highest available rating. A conditional or unsatisfactory DOT safety rating could adversely affect our business because some of our customer contracts may require a satisfactory DOT safety rating, and a conditional or unsatisfactory rating could negatively impact or restrict our operations.

Our motor carrier operations are also subject to environmental laws and regulations, including laws and regulations dealing with underground fuel storage tanks, the transportation of hazardous materials and other environmental matters, and our operations involve certain inherent environmental risks. We maintain one bulk fuel storage above ground tank and fuel island. Our operations involve the risks of fuel spillage or seepage, environmental damage, and hazardous waste disposal, among others. We have instituted programs to monitor and control environmental risks and assure compliance with applicable environmental laws. As part of our safety and risk management program, we periodically perform internal environmental reviews so that we can achieve environmental compliance and avoid environmental risk. We transport a minimum amount of environmentally hazardous substances and, to date, have experienced no significant claims for hazardous materials shipments. If we should fail to comply with applicable regulations, we could be subject to substantial fines or penalties and to civil and criminal liability.

Company operations conducted in industrial areas, where truck terminals and other industrial activities are conducted, and where groundwater or other forms of environmental contamination have occurred, potentially expose us to claims that we contributed to the environmental contamination.

We believe we are currently in material compliance with applicable laws and regulations and that the cost of compliance has not materially affected results of operations.

In addition to environmental regulations directly affecting our business, we are also subject to the effects of the new truck engine design requirements implemented by the EPA. See "Revenue Equipment" above.

Item 1A. Risk Factors.

Set forth below, and elsewhere in this Report and in other documents we file with the SEC, are risks and uncertainties that could cause our actual results to differ materially from the results contemplated by the forward-looking statements contained in this Report.

Our business is subject to general economic and business factors that are largely beyond our control, any of which could have a material adverse effect on our operating results.

Our business is dependent upon a number of general economic and business factors that may adversely affect our results of operations. These factors include significant increases or rapid fluctuations in fuel prices, excess capacity in the trucking industry, surpluses in the market for used equipment, interest rates, fuel taxes, license and registration fees, insurance premiums, self-insurance levels, and difficulty in attracting and retaining qualified drivers and independent contractors.

We operate in a highly competitive and fragmented industry, and our business may suffer if we are unable to adequately address any downward pricing pressures or other factors that may adversely affect our ability to compete with other carriers.

Further, we are affected by recessionary economic cycles and downturns in customers’ business cycles, particularly in market segments and industries, such as the automotive industry, where we have a significant concentration of customers. Economic conditions may also adversely affect our customers and their ability to pay for our services.

Deterioration in the United States and world economies could exacerbate any difficulties experienced by our customers and suppliers in obtaining financing, which, in turn, could materially and adversely impact our business, financial condition, results of operations and cash flows.

- 8 -

Numerous competitive factors could impair our ability to operate at an acceptable profit. These factors include, but are not limited to, the following:

· we compete with many other truckload carriers of varying sizes and, to a lesser extent, with less-than-truckload carriers and railroads, some of which have more equipment and greater capital resources than we do;

· some of our competitors periodically reduce their freight rates to gain business, especially during times of reduced growth rates in the economy, which may limit our ability to maintain or increase freight rates, maintain our margins or maintain significant growth in our business;

· many customers reduce the number of carriers they use by selecting so-called “core carriers” as approved service providers, and in some instances we may not be selected;

· many customers periodically accept bids from multiple carriers for their shipping needs, and this process may depress freight rates or result in the loss of some of our business to competitors;

· the trend toward consolidation in the trucking industry may create other large carriers with greater financial resources and other competitive advantages relating to their size and with whom we may have difficulty competing;

· advances in technology require increased investments to remain competitive, and our customers may not be willing to accept higher freight rates to cover the cost of these investments;

· competition from Internet-based and other logistics and freight brokerage companies may adversely affect our customer relationships and freight rates; and

· economies of scale that may be passed on to smaller carriers by procurement aggregation providers may improve their ability to compete with us.

We are highly dependent on our major customers, the loss of one or more of which could have a material adverse effect on our business.

A significant portion of our revenue is generated from our major customers. For 2013, our top five customers, based on revenue, accounted for approximately 43% of our revenue, and our two largest customers, General Motors Corporation and Chrysler, accounted for approximately 21% and 12% of our revenue, respectively. We also provide transportation services to other manufacturers who are suppliers for automobile manufacturers. As a result, the concentration of our business within the automobile industry is greater than the concentration in a single customer. Approximately 46% of our revenues for 2013 were derived from transportation services provided to the automobile industry.

Generally, we do not have long-term contractual relationships with our major customers, and we cannot assure that our customer relationships will continue as presently in effect. A reduction in or termination of our services by our major customers could have a material adverse effect on our business and operating results.

We may be adversely impacted by fluctuations in the price and availability of diesel fuel.

Diesel fuel represents a significant operating expense for the Company and we do not currently hedge against the risk of diesel fuel price increases. An increase in diesel fuel prices or diesel fuel taxes, or any change in federal or state regulations that results in such an increase, could have a material adverse effect on our operating results to the extent we are unable to recoup such increases from customers in the form of increased freight rates or through fuel surcharges. Historically, we have been able to offset, to a certain extent, diesel fuel price increases through fuel surcharges to our customers but we cannot be certain that we will be able to do so in the future. We continuously monitor the components of our pricing, including base freight rates and fuel surcharges, and address individual account profitability issues with our customers when necessary. While we have historically been able to adjust our pricing to help offset changes to the cost of diesel fuel, through changes to base rates and/or fuel surcharges, we cannot be certain that we will be able to do so in the future.

- 9 -

Difficulty in attracting drivers could affect our profitability and ability to grow.

Periodically, the transportation industry experiences difficulty in attracting and retaining qualified drivers, including independent contractors, resulting in intense competition for drivers. We have from time to time experienced under-utilization and increased expenses due to a shortage of qualified drivers. If we are unable to attract drivers when needed or contract with independent contractors when needed, we could be required to further adjust our driver compensation packages or let trucks sit idle, which could adversely affect our growth and profitability.

If we are unable to retain our key employees, our business, financial condition and results of operations could be harmed.

We are highly dependent upon the services of our key employees and executive officers. The loss of any of their services could have a material adverse effect on our operations and future profitability. We must continue to develop and retain a core group of managers if we are to realize our goal of expanding our operations and continuing our growth. We cannot assure that we will be able to do so.

Ongoing insurance and claims expenses could significantly reduce our earnings.

Our future insurance and claims expenses might exceed historical levels, which could reduce our earnings. The Company is self insured for health and workers’ compensation insurance coverage up to certain limits. If medical costs continue to increase, or if the severity or number of claims increase, and if we are unable to offset the resulting increases in expenses with higher freight rates, our earnings could be materially and adversely affected.

Purchase price increases for new revenue equipment and/or decreases in the value of used revenue equipment could have an adverse effect on our results of operations, cash flows and financial condition.

During the last decade, the purchase price of new revenue equipment has increased significantly as equipment manufacturers recover increased materials costs and engine design costs resulting from compliance with increasingly stringent EPA engine emission standards. The final phase of the new EPA engine design requirements were effective in 2010; however, additional EPA emission mandates in the future could result in higher purchase prices of revenue equipment which could result in higher than anticipated depreciation expenses. If we were unable to offset any such increase in expenses with freight rate increases, our cash flows and results of operations could be adversely affected. If the market prices for used revenue equipment declines, we could incur substantial losses upon disposition of our revenue equipment which could adversely affect our results of operations and financial condition.

We have significant ongoing capital requirements that could affect our liquidity and profitability if we are unable to generate sufficient cash from operations or obtain sufficient financing on favorable terms.

The trucking industry is capital intensive. If we are unable to generate sufficient cash from operations in the future, we may have to limit our growth, enter into unfavorable financing arrangements, or operate our revenue equipment for longer periods, any of which could have a material adverse effect on our profitability.

- 10 -

We have a substantial amount of debt, which could restrict our growth, place us at a competitive disadvantage or otherwise materially adversely affect our financial health. Our substantial debt levels could have important consequences such as the following:

· impair our ability to obtain additional future financing for working capital, capital expenditures, acquisitions or general corporate expenses;

· limit our ability to use operating cash flow in other areas of our business due to the necessity of dedicating a substantial portion of these funds for payments on our indebtedness;

· limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate;

· make it more difficult for us to satisfy our obligations;

· increase our vulnerability to general adverse economic and industry conditions; and

· place us at a competitive disadvantage compared to our competitors.

Our ability to make scheduled payments on, or to refinance, our debt and other obligations will depend on our financial and operating performance, which, in turn, is subject to our ability to implement our strategic initiatives, prevailing economic conditions and certain financial, business and other factors beyond our control. If our cash flow and capital resources are insufficient to fund our debt service and other obligations, we may be forced to reduce or delay expansion plans and capital expenditures, sell material assets or operations, obtain additional capital or restructure our debt. We cannot provide any assurance that our operating performance, cash flow and capital resources will be sufficient to pay our debt obligations when they become due. We also cannot provide assurance that we would be able to dispose of material assets or operations or restructure our debt or other obligations if necessary or, even if we were able to take such actions, that we could do so on terms that are acceptable to us.

Disruptions in the credit markets may adversely affect our business, including the availability and cost of short-term funds for liquidity requirements and our ability to meet long-term commitments, which could adversely affect our results of operations, cash flows and financial condition.

If cash from operations is not sufficient, we may be required to rely on the capital and credit markets to meet our financial commitments and short-term liquidity needs. Disruptions in the capital and credit markets, as have been experienced during recent years, could adversely affect our ability to draw on our bank revolving credit facility. Our access to funds under the credit facility is dependent on the ability of banks to meet their funding commitments. A bank may not be able to meet their funding commitments if they experience shortages of capital and liquidity or if they experience excessive volumes of borrowing requests from other borrowers within a short period of time.

Longer term disruptions in the capital and credit markets as a result of uncertainty, changing or increased regulation, reduced alternatives, or failures of significant financial institutions could adversely affect our access to liquidity needed for our business. Any disruption could require us to take measures to conserve cash until the markets stabilize or until alternative credit arrangements or other funding for our business needs can be arranged, which could adversely affect our growth and profitability.

- 11 -

We operate in a highly regulated industry and increased costs of compliance with, or liability for violation of, existing or future regulations could have a material adverse effect on our business.

The DOT and various state agencies exercise broad powers over our business, generally governing such activities as authorization to engage in motor carrier operations, safety, and financial reporting. We may also become subject to new or more restrictive regulations relating to fuel emissions, drivers’ hours of service, and ergonomics. Compliance with such regulations could substantially impair equipment productivity and increase our operating expenses.

The EPA adopted new emission control regulations, which required progressive reductions in exhaust emissions from diesel engines through 2010. In order to partially offset the costs of compliance with the new EPA engine design requirements, manufacturers have increased new equipment prices and eliminated or sharply reduced the price of repurchase or trade-in commitments. If new equipment prices continue to increase, or if the price of repurchase commitments by equipment manufacturers were to decrease more than anticipated, we may be required to increase our depreciation and financing costs and/or retain some of our equipment longer, which may result in an increase in maintenance expenses. To the extent we are unable to offset any such increases in expenses with rate increases or cost savings, our results of operations would be adversely affected. If our fuel or maintenance expenses were to increase as a result of our use of the new, EPA-compliant engines, and we are unable to offset such increases with fuel surcharges or higher freight rates, our results of operations would be adversely affected. Further, our business and operations could be adversely impacted if we experience problems with the reliability of the new engines. Although we have not experienced any significant reliability issues with these engines to date, the expenses associated with the trucks containing these engines have been slightly elevated, primarily as a result of higher depreciation expense due to increased purchase prices.

During 2010, the FMCSA implemented its “Compliance, Safety, Accountability” program (“CSA”), formerly known as “Comprehensive Safety Analysis 2010” or “CSA 2010”. CSA is an enforcement and compliance initiative that provides for driver standards in addition to the carrier standards previously in place. Under CSA, the methodology for determining a carrier's DOT safety rating has been expanded to include the on-road safety performance of the carrier's drivers. As a result of these new regulations, including the expanded methodology for determining a carrier's DOT safety rating, there may be an adverse effect on our DOT safety rating. We currently have a satisfactory DOT rating, which is the highest available rating. A conditional or unsatisfactory DOT safety rating could adversely affect our business because some of our customer contracts may require a satisfactory DOT safety rating, and a conditional or unsatisfactory rating could negatively impact or restrict our operations.

During December 2011, the FMCSA published final HOS rules which included changes that placed limits on the 34-hour restart provision and added required driver breaks. These final HOS rules have made an impact on the utilization of our equipment and our drivers’ productivity however, they have not had a significant negative impact on our operations.

We are subject to certain risks arising from doing business in Mexico.

As we continue to grow our business in Mexico, we are subject to greater risks of doing business internationally, including fluctuations in foreign currencies, 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 U.S. export and import laws, and social, political, and economic instability. We also face additional risks associated with our Mexico business, including potential restrictive trade policies and imposition of duties, taxes, or government royalties imposed by the Mexican government. If we are unable to address business concerns related to our international operations in a timely and cost efficient manner, our financial position, results of operations or cash flows could be adversely affected.

- 12 -

A determination by regulators that owner-operators are employees, rather than independent contractors, could expose us to various liabilities and additional costs.

Tax and other regulatory authorities often seek to assert that independent contractors in the transportation service industry, such as our owner-operators, are employees rather than independent contractors. There can be no assurance that these interpretations and tax laws that consider these persons independent contractors will not change or that these authorities will not successfully assert this position. If our owner-operators are determined to be our employees, that determination could materially increase our exposure under a variety of federal and state tax, workers’ compensation, unemployment benefits, labor, employment and tort laws, as well as our potential liability for employee benefits. In addition, such changes may be applied retroactively, and if so, we may be required to pay additional amounts to compensate for prior periods. Any of the above increased costs would adversely affect our business and operating results.

Our results of operations may be affected by seasonal factors.

Our productivity may decrease during the winter season when severe winter weather impedes operations. Also, some shippers may reduce their shipments after the winter holiday season. At the same time, operating expenses may increase and fuel efficiency may decline due to engine idling during periods of inclement weather. Harsh weather conditions generally also result in higher accident frequency, increased freight claims, and higher equipment repair expenditures.

Our business may be disrupted by natural disasters and severe weather conditions causing supply chain disruptions.

Natural disasters such as earthquakes, tsunamis, hurricanes, tornadoes, floods or other adverse weather and climate conditions, whether occurring in the United States or abroad, could disrupt our operations or the operations of our customers or could damage or destroy infrastructure necessary to transport products as part of the supply chain. Specifically, these events may damage or destroy or assets, disrupt fuel supplies, increase fuel costs, disrupt freight shipments or routes, and affect regional economies. As a result, these events could make it difficult or impossible for us to provide logistics and transportation services; disrupt or prevent our ability to perform functions at the corporate level; and/or otherwise impede our ability to continue business operations in a continuous manner consistent with the level and extent of business activities prior to the occurrence of the unexpected event, which could adversely affect our business and results of operations or make our results more volatile.

We may incur additional operating expenses or liabilities as a result of potential future requirements to address climate change issues.

As global warming issues become more prevalent, federal, state and local governments as well as some of our customers, are beginning to respond to these issues. This increased focus on sustainability may result in new legislation or regulations and customer requirements that could negatively affect us as we may incur additional costs or be required to make changes to our operations in order to comply with any new regulations or customer requirements. Legislation or regulations that potentially impose restrictions, caps, taxes, or other controls on emissions of greenhouse gases such as carbon dioxide, a by-product of burning fossil fuels such as those used in the Company’s trucks, could adversely affect our operations and financial results. More specifically, legislative or regulatory actions related to climate change could adversely impact the Company by increasing our fuel costs and reducing fuel efficiency and could result in the creation of substantial additional capital expenditures and operating costs in the form of taxes, emissions allowances, or required equipment upgrades. Any of these factors could impair our operating efficiency and productivity and result in higher operating costs. In addition, revenues could decrease if we are unable to meet regulatory or customer sustainability requirements. These additional costs, changes in operations, or loss of revenues could have a material adverse effect on our business, financial condition and results of operations.

Our operations are subject to various environmental laws and regulations, the violation of which could result in substantial fines or penalties.

We are subject to various environmental laws and regulations dealing with the handling of hazardous materials, underground fuel storage tanks, and discharge and retention of storm-water. We operate in industrial areas, where truck terminals and other industrial activities are located, and where groundwater or other forms of environmental contamination could occur. In prior years, we also maintained bulk fuel storage and fuel islands at two of our facilities. Our operations may involve the risks of fuel spillage or seepage, environmental damage, and hazardous waste disposal, among others. If we are involved in a spill or other accident involving hazardous substances, or if we are found to be in violation of applicable laws or regulations, it could have a materially adverse effect on our business and operating results. If we should fail to comply with applicable environmental regulations, we could be subject to substantial fines or penalties and to civil and criminal liability.

If our employees were to unionize, our operating costs would increase and our ability to compete would be impaired.

None of our employees is currently represented by a collective bargaining agreement. However, we can offer no assurance that our employees will not unionize in the future, particularly if legislation is passed that facilitates unionization. If our employees were to unionize, our operating costs would increase and our profitability could be adversely affected.

Our information technology systems are subject to certain risks that are beyond our control.

We depend on the proper functioning and availability of our information systems, including communications and data processing systems, in operating our business. Although we have implemented redundant systems and network security measures, our information technology remains susceptible to outages, computer viruses, break-ins and similar disruptions that may inhibit our ability to provide services to our customers and the ability of our customers to access our systems. This may result in the loss of customers or a reduction in demand for our services, which could adversely affect our growth and profitability.

We have substantial fixed costs and, as a result, our operating income fluctuates disproportionately with changes in our net sales.

A significant portion of our expenses are fixed costs that that neither increase nor decrease proportionately with sales. There can be no assurance that we would be able to reduce our fixed costs proportionately in response to a decline in our sales and therefore our competitiveness could be significantly impacted. As a result, a decline in our sales would result in a higher percentage decline in our income from operations and net income.

Our financial results may be adversely impacted by potential future changes in accounting practices.

Future changes in accounting standards or practices, and related legal and regulatory interpretations of those changes, may adversely impact public companies in general, the transportation industry or our operations specifically. New accounting standards or requirements, such as a conversion from U.S. Generally Accepted Accounting Principles to International Financial Reporting Standards, could change the way we account for, disclose and present various aspects of our financial position, results of operations or cash flows and could be costly to implement.

Our business may be harmed by terrorist attacks, future war or anti-terrorism measures.

In order to prevent terrorist attacks, federal, state and municipal authorities have implemented and continue to follow various security measures, including checkpoints and travel restrictions on large trucks. Our international operations in Canada and Mexico may be affected significantly if there are any disruptions or closures of border traffic due to security measures. Such measures may have costs associated with them, which, in connection with the transportation services we provide, we or our owner-operators could be forced to bear. In addition, war or risk of war also may have an adverse effect on the economy. A decline in economic activity could adversely affect our revenue or restrict our future growth. Instability in the financial markets as a result of terrorism or war also could affect our ability to raise capital. In addition, the insurance premiums charged for some or all of the coverage currently maintained by us could increase dramatically or such coverage could be unavailable in the future.

We may be unable to successfully integrate businesses we acquire into our operations.

Integrating businesses we acquire may involve unanticipated delays, costs or other operational or financial problems. Successful integration of the businesses we acquire depends on a number of factors, including our ability to transition acquired companies to our management information systems. In integrating businesses we acquire, we may not achieve expected economies of scale or profitability or realize sufficient revenues to justify our investment. We also face the risk that an unexpected problem at one of the companies we acquire will require substantial time and attention from senior management, diverting management’s attention from other aspects of our business. We cannot be certain that our management and operational controls will be able to support us as we grow.

The Chairman of our board of directors holds a controlling interest in us; therefore, the influence of our public shareholders over significant corporate actions is limited, and we are not subject to certain corporate governance standards that apply to other publicly traded companies.

Matthew T. Moroun, the Chairman of our Board of Directors, and a trust of which Mr. Moroun is a co-trustee together, own approximately 59.3% of our outstanding common stock. As a result, Mr. Moroun has the power to:

· control all matters submitted to our shareholders;

· elect our directors;

· adopt, extend or remove any anti-takeover provisions that are available to us; and

· exercise control over our business, policies and affairs.

This concentration of ownership could limit the price that some investors might be willing to pay for shares of our common stock, and our ability to engage in significant transactions, such as a merger, acquisition or liquidation, will require the consent of Mr. Moroun. Conflicts of interest could arise between us and Mr. Moroun, and any conflict of interest may be resolved in a manner that does not favor us. Accordingly, Mr. Moroun could cause us to enter into transactions or agreements of which our other shareholders would not approve or make decisions with which they may disagree. Because of Mr. Moroun’s level of ownership, we have elected to be treated as a controlled company in accordance with the rules of the NASDAQ Stock Market. Accordingly, we are not required to comply with NASDAQ Stock Market rules which would otherwise require a majority of our Board to be comprised of independent directors and require our Board to have a compensation committee and a nominating and corporate governance committee comprised of independent directors.

Mr. Moroun may continue to retain control of us for the foreseeable future and may decide not to enter into a transaction in which shareholders would receive consideration for our common stock that is much higher than the then-current market price of our common stock. In addition, Mr. Moroun could elect to sell a controlling interest in us to a third-party and our other shareholders may not be able to participate in such transaction or, if they are able to participate in such a transaction, such shareholders may receive less than the then current fair market value of their shares. Any decision regarding ownership of us that Mr. Moroun may make at some future time will be in his absolute discretion, subject to applicable laws and fiduciary duties.

Our stock trading volume may not provide adequate liquidity for investors.

- 15 -

Although shares of our common stock are traded on the NASDAQ Global Market, the average daily trading volume in our common stock is less than that of other larger transportation and logistics companies. A public trading market having the desired characteristics of depth, liquidity and orderliness depends on the presence in the marketplace of a sufficient number of willing buyers and sellers of the common stock at any given time. This presence depends on the individual decisions of investors and general economic and market conditions over which we have no control. Given the daily average trading volume of our common stock, significant sales of the common stock in a brief period of time, or the expectation of these sales, could cause a decline in the price of our common stock. Additionally, low trading volumes may limit a stockholder’s ability to sell shares of our common stock.

We currently do not intend to pay future dividends on our common stock.

We currently do not anticipate paying future cash dividends on our common stock. We anticipate that we will retain all of our future earnings, if any, for use in the development and expansion of our business and for general corporate purposes. Any determination to pay future dividends and other distributions in cash, stock, or property by the Company in the future will be at the discretion of our Board of Directors and will be dependent on then-existing conditions, including our financial condition and results of operations and contractual restrictions. Therefore, you should not rely on future dividend income from shares of our common stock.

Item 2. Properties.

Our executive offices and primary terminal facilities, which we own, are located in Tontitown, Arkansas. These facilities are located on approximately 49.3 acres and consist of 114,403 square feet of office space and maintenance and storage facilities.

Our subsidiaries lease facilities in Indianapolis, Indiana; Romulus, Michigan; North Jackson, Ohio; Tahlequah, Oklahoma; Bath, Pennsylvania; El Paso, Texas; and Monterrey, Mexico. Our terminal facilities in Columbia, Mississippi; Irving and Laredo, Texas; North Little Rock, Arkansas; and Willard, Ohio are owned. The leased facilities are leased primarily on contractual terms typically ranging from one to five years. As of December 31, 2013, the following table provides a summary of the ownership and types of activities conducted at each location:

Location	Own/ Lease	Dispatch Office	Maintenance Facility	Safety Training
Tontitown, Arkansas	Own	Yes	Yes	Yes
North Little Rock, Arkansas	Own	No	Yes	Yes
Indianapolis, Indiana	Lease	No	Yes	No
Romulus, Michigan	Lease	No	Yes	No
Columbia, Mississippi	Own	No	No	No
North Jackson, Ohio	Lease	Yes	Yes	Yes
Willard, Ohio	Own	Yes	Yes	No
Tahlequah, Oklahoma	Lease	No	No	No
Bath, Pennsylvania	Lease	No	Yes	No
El Paso, Texas	Lease	No	No	No
Irving, Texas	Own	Yes	Yes	Yes
Laredo, Texas	Own	Yes	Yes	Yes
Monterrey, Mexico	Lease	No	No	No

We also have access to trailer drop and relay stations in various other locations across the country. We lease certain of these facilities on a month-to-month basis from affiliates of our largest stockholder.

We believe that all of the properties that we own or lease are suitable for their purposes and adequate to meet our needs.

Item 3. Legal Proceedings.

The nature of our business routinely results in litigation, primarily involving claims for personal injuries and property damage incurred in the transportation of freight. We believe that all such routine litigation is adequately covered by insurance and that adverse results in one or more of those cases would not have a material adverse effect on our financial statements.

We are a defendant in a collective-action lawsuit which was filed on August 22, 2013, in the United States District Court for the Western District of Arkansas. The plaintiffs, who are current and former drivers and who worked for the Company during the period of August 22, 2010, through the date of the filing, allege claims for unpaid wages under the Fair Labor Standards Act and the Arkansas Minimum Wage Law. The complaint alleges that the Company failed to pay newly hired drivers minimum wage during orientation, training, and while traveling during normal business hours and that the Company failed to pay all drivers when working on assignment for more than 24 hours. The plaintiffs seek to enjoin the Company from continuing its current pay practices related to the allegations. They also seek actual damages, liquidated damages equal to accrual damages, court costs, and legal fees. The lawsuit is currently in the discovery stage. We cannot reasonably estimate at this time the possible loss or range of loss, if any, that may arise from this lawsuit. Management has determined that any losses under this claim would not be covered by exisiting insurance policies.

Fourth Quarter		10.89		8.81		1.00

As of February 17, 2013, there were approximately 105 holders of record of our common stock.

Dividends

The Company paid cash dividends of $1.00 per common share during each of the months of April 2012 and December 2012. No other dividends have been paid during any year prior to 2012 or during 2013. Future dividend policy and the payment of dividends, if any, will be determined by the Board of Directors in light of circumstances then existing, including our earnings, financial condition and other factors deemed relevant by the Board of Directors. Currently, the Company does not intend to pay dividends in the foreseeable future.

Repurchases of Equity Securities by the Issuer

The Company’s stock repurchase program has been extended and expanded several times, most recently in September 2011, when the Board of Directors announced that it had authorized the Company to repurchase up to 500,000 additional shares of its common stock. The Company repurchased 224,000 shares of its common stock during the fourth quarter of 2011 but did not repurchase any shares of its common stock during 2012 under the program. The Company did however, repurchase 50,325 shares of its common stock under the program during 2013.

On December 2, 2013, the Company announced a Dutch auction tender offer (the “tender offer”) to repurchase up to 600,000 shares of its common stock, par value $0.01 per share, subject to the terms and conditions described in the tender offer pursuant to the Board of Directors approval on November 27, 2013. Subject to certain limitations and legal requirements, the Company could purchase up to an additional 2% of its outstanding shares which totaled 173,000 shares. The tender offer began on the date of the announcement, December 2, 2013 and expired on December 30, 2013.

- 18 -

Through the tender offer, the Company’s shareholders had the opportunity to tender some or all of their shares at a price within the range of $19.00 to 21.00 per share. Upon expiration of the offer, the Company accepted for purchase a total of 675,000 shares at a price of $20.50 per share, for a total purchase price of approximately $13.9 million, including fees and commission. The purchases were settled on January 6, 2014. The Company accounted for the repurchase of these shares as treasury stock on the Company’s consolidated balance sheet as of December 31, 2013.

The following table summarizes the Company's common stock repurchases during the fourth quarter of 2013. No shares were purchased during the quarter other than through the repurchase program and the tender offer described above. All purchases were made by or on behalf of the Company and not by any “affiliated purchaser”.

Period	Total number of shares purchased		Average price paid per share		Total number of shares purchased as part of publicly announced plans or programs		Maximum  number of shares that may yet be purchased under the plans or programs
October 1-31, 2013		2,100	$	16.98		2,100		225,675
November 1-30, 2013		-		-		-		225,675
December 1-31, 2013		675,000		20.50		675,000		225,675
Total		677,100	$	20.49		677,100

Performance Graph

We have historically used the Center for Research in Security Prices (CRSP) Total Return Index for the NASDAQ Stock Market (U.S. companies) and the CRSP Total Return Index for the NASDAQ Trucking and Transportation Stocks but as a result of a change in the total return data made available to us through our vendor provider, our performance graphs going forward will use comparable indexes provided by NASDAQ OMX Global Indexes. The historically used indexes will be replaced by the NASDAQ OMX Index for the NASDAQ Stock Market (U.S. companies) and the NASDAQ OMX Index for the NASDAQ Trucking and Transportation Stocks.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Business Overview

The Company's administrative headquarters are in Tontitown, Arkansas. From this location we manage operations conducted through our wholly owned subsidiaries based in various locations around the United States, Mexico, and Canada. The operations of these subsidiaries can generally be classified into either truckload services or brokerage and logistics services. Truckload services include those transportation services in which we utilize company owned trucks or owner-operator owned trucks. Brokerage and logistics services consist of services such as transportation scheduling, routing, mode selection, transloading and other value added services related to the transportation of freight which may or may not involve the usage of company owned or owner-operator owned equipment. Both our truckload operations and our brokerage/logistics operations have similar economic characteristics and are impacted by virtually the same economic factors as discussed elsewhere in this Report. All of the Company's operations are in the motor carrier segment.

For both operations, substantially all of our revenue is generated by transporting freight for customers and is predominantly affected by the rates per mile received from our customers, equipment utilization, and our percentage of non-compensated miles. These aspects of our business are carefully managed and efforts are continuously underway to achieve favorable results. Truckload services revenues, excluding fuel surcharges, represented 92.6%, 91.8% and 93.5% of total revenues, excluding fuel surcharges for the twelve months ended December 31, 2013, 2012 and 2011, respectively.

- 23 -

The main factors that impact our profitability on the expense side are costs incurred in transporting freight for our customers. Currently, our most challenging costs include fuel, driver recruitment, training, wage and benefit costs, independent broker costs (which we record as purchased transportation), insurance, and maintenance and capital equipment costs.

In discussing our results of operations we use revenue, before fuel surcharge, (and fuel expense, net of surcharge), because management believes that eliminating the impact of this sometimes volatile source of revenue allows a more consistent basis for comparing our results of operations from period to period. During 2013, 2012 and 2011, approximately $89.7 million, $82.9 million and $75.1 million, respectively, of the Company's total revenue was generated from fuel surcharges. We also discuss certain changes in our expenses as a percentage of revenue, before fuel surcharge, rather than absolute dollar changes. We do this because we believe the high variable cost nature of certain expenses makes a comparison of changes in expenses as a percentage of revenue more meaningful than absolute dollar changes.

Results of Operations - Truckload Services

The following table sets forth, for truckload services, the percentage relationship of expense items to operating revenues, before fuel surcharges, for the periods indicated. Fuel costs are shown net of fuel surcharges.

(1) In order to conform to industry practice, the Company began to classify payments to third-party owner operator drivers as purchased transportation rather than as salaries, wages and benefits as had been presented in reports prior to the period ended September 30, 2013. This reclassification has no effect on operating income, net income or earnings per share. The Company has made corresponding reclassifications to comparative periods shown.

2013 Compared to 2012

For the year ended December 31, 2013, truckload services revenue, before fuel surcharges, increased 6.1% to $290.1 million as compared to $273.4 million for the year ended December 31, 2012. The increase related primarily to an increase in the number of miles traveled, a reduction in uncompensated miles, and an increase in the average rate charged to customers. The number of miles traveled increased from 200.8 million miles during 2012 to 209.8 million miles during 2013 primarily as a result of an increase in the average number of trucks in service, which increased from 1,760 during 2012 to 1,804 during 2013. The average percentage of uncompensated miles declined from 8.7% of total miles during 2012 to 7.3% of total miles during 2013. The average rate charged per total mile during 2013 increased $0.02 as compared to the average rate charged during 2012. Also contributing to the increase was an increase in equipment utilization as the Company continues to replace older trucks, which generally have a higher probability for mechanical problems which could disrupt en route service thereby reducing route efficiency.

- 24 -

Salaries, wages and benefits decreased from 39.7% of revenues, before fuel surcharges, during 2012 to 36.7% of revenues, before fuel surcharges, during 2013. The decrease related primarily to a decrease in Company driver wages paid during 2013 as compared to Company driver wages paid during 2012. Our driver pool consists of both company divers and third-party owner operators. Company drivers are employees of the Company and perform services in company-owned equipment while owner-operator drivers provide services, under contract, using their own equipment. While each group is generally compensated on a per-mile basis, owner-operator payments are classified in the Company’s financial statements under the Rent and purchased transportation category. The percentage-based decrease in Salaries, wages and benefits resulted from a decrease in the proportion of total miles driven by company drivers during 2013 in comparison to the proportion of total miles driven by company drivers during 2012. This proportional decrease was the result of an increase in the average number of owner operators under contract from 149 during 2012 to 322 during 2013 and a corresponding decrease in the average number of company drivers. On a dollar basis, total salaries, wages and benefits decreased from $108.4 million during 2012 to $106.4 million during 2013. Partially offsetting the decrease was an increase in costs associated with workers’ compensation benefits during the 2013 as compared to 2012.

Fuel expense, net of fuel surcharge, decreased from 10.4% of revenues, before fuel surcharges, during 2012 to 2.7% of revenues, before fuel surcharges, during 2013. The decrease relates primarily to a decrease in the average surcharge-adjusted fuel price paid per gallon of diesel fuel and to an increase in the average miles-per-gallon (“mpg”) experienced. The average surcharge-adjusted fuel price paid per gallon of diesel fuel decreased as a result of more favorable fuel surcharge arrangements made with customers and to an increase in the number of owner operators in our fleet. Fuel surcharge collections can fluctuate significantly from period to period as they are generally based on changes in fuel prices from period to period so that during periods of rising fuel prices fuel surcharge collections increase while fuel surcharge collections decrease during periods of falling fuel prices. Fuel surcharge revenue generated from transportation services performed by owner operators is reflected as a reduction in net fuel expense, while fuel surcharges paid to owner operators for their services is reported along with their base rate of pay in the Rent and purchased transportation category. These categorizations have the effect of reducing our net fuel expense while increasing the Rent and purchased transportation category, as discussed above. The average mpg experienced increased during 2013 as compared to the mpg experienced during 2012 as a result of replacing older trucks with newer trucks, which are more fuel efficient.

Rent and purchased transportation increased from 11.3% of revenues, before fuel surcharges, during 2012 to 21.9% of revenues, before fuel surcharges, during 2013. The increase relates primarily to an increase in driver lease expense as the average number of owner operators under contract increased from 149 during 2012 to 322 during 2013. The increase in costs in this category, as they relate to the increase in owner operators, are partially offset by a decrease in other cost categories, such as repairs and fuel, which are generally borne by the owner operator.

Depreciation decreased from 14.0% of revenues, before fuel surcharges, during 2012 to 13.5% of revenues, before fuel surcharges, during 2013. The percentage-based decrease relates primarily to the interaction of the fixed-cost characteristic of depreciation expense with an increase in revenues for the periods compared.

Operating supplies and expenses decreased from 14.3% of revenues, before fuel surcharges, during 2012 to 12.0% of revenues, before fuel surcharges, during 2013. The decrease related primarily to a decrease in amounts paid for equipment maintenance costs during 2013 as compared to amounts paid during 2012 as a result of replacing older equipment with new equipment. Partially offsetting this decrease was an increase in amounts paid for driver training schools during 2013 as compared to amounts paid during 2012. The increase in driver training and recruiting costs are a result of heightened competition for qualified drivers as industry demand has increased and increased regulations have forced some drivers to exit the profession.

- 25 -

Operating taxes and licenses decreased from 1.8% of revenues, before fuel surcharges, during 2012 to 1.7% of revenues, before fuel surcharges, during 2013. The decrease related primarily to a decrease in amounts paid for equipment registration fees from $5.0 million during 2012 to $4.9 million during 2013.

Other expenses increased from 1.9% of revenues, before fuel surcharges, during 2012 to 2.3% of revenues, before fuel surcharges, during 2013. The increase relates primarily to an increase in amounts expensed for uncollectible revenue, professional services, and for other supplies and expenses.

The truckload services division operating ratio, which measures the ratio of operating expenses, net of fuel surcharges, to operating revenues, before fuel surcharges, improved to 96.3% for 2013 from 99.2% for 2012.

Non-operating income decreased from 1.2% of revenues, before fuel surcharges, during 2012 to 0.5% of revenues, before fuel surcharges, during 2013. The components of this category consist primarily of dividends earned and gains or losses on the Company’s investments in marketable equity securities. The decrease relates primarily to a decrease in the amount of gains recognized between the periods on the Company’s investments in marketable equity securities.

2012 Compared to 2011

For the year ended December 31, 2012, truckload services revenue, before fuel surcharges, increased 2.9% to $273.4 million as compared to $265.8 million for the year ended December 31, 2011. The increase relates primarily an increase in the average number of miles traveled per unit each work day from 434 miles during 2011 to 449 miles during 2012.

Salaries, wages and benefits decreased from 41.3% of revenues, before fuel surcharges, during 2011 to 39.7% of revenues, before fuel surcharges, during 2012.  The decrease related primarily to a decrease in expenses associated with workers’ compensation benefits. To a lesser extent, the decrease related to a decrease in company driver wages paid during 2012 as compared to company driver wages paid during 2011. Our driver pool consists of both company divers and third-party owner operators. Company drivers are employees of the Company and perform services in company-owned equipment while owner-operator drivers provide services, under contract, using their own equipment. While each group is generally compensated on a per-mile basis, owner-operator payments are classified in the Company’s financial statements under the Rent and purchased transportation category. The percentage-based decrease in Salaries, wages and benefits resulted from a decrease in the proportion of total miles driven by company drivers during 2012 in comparison to the proportion of total miles driven by company drivers during 2011. This proportional decrease was the result of an increase in the average number of owner operators under contract from 48 during 2011 to 149 during 2012. On a dollar basis, total salaries, wages and benefits decreased from $109.7 million during 2011 to $108.4 million during 2012. Offsetting the majority of the decrease in company driver wages was an increase in general and administrative wages paid during 2012 as compared to 2011. Partially offsetting the decrease was an increase in costs associated with group health benefits paid during 2012 as compared to 2011.

Fuel expense, net of fuel surcharge, decreased from 18.8% of revenues, before fuel surcharges, during 2011 to 10.4% of revenues, before fuel surcharges, during 2012. The decrease relates primarily to a decrease in the average surcharge-adjusted fuel price paid per gallon of diesel fuel and to an increase in the average miles-per-gallon (“mpg”) experienced. The average surcharge-adjusted fuel price paid per gallon of diesel fuel decreased as a result of more favorable fuel surcharge arrangements made with customers and to an increase in the number of owner operators in our fleet. Fuel surcharge collections can fluctuate significantly from period to period as they are generally based on changes in fuel prices from period to period so that during periods of rising fuel prices fuel surcharge collections increase while fuel surcharge collections decrease during periods of falling fuel prices. Fuel surcharge revenue generated from transportation services performed by owner operators is reflected as a reduction in net fuel expense, while fuel surcharges paid to owner operators for their services is reported along with their base rate of pay in the Rents and purchased transportation category. These categorizations have the effect of reducing our net fuel expense while increasing Rents and purchased transportation category, as discussed above. The average mpg experienced increased during 2012 as compared to the mpg experienced during 2011 as a result of replacing older trucks with newer trucks, which are more fuel efficient and to the implementation of driver bonus programs which are tied directly to fuel efficiency.

- 26 -

Rent and purchased transportation increased from 4.7% of revenues, before fuel surcharges, during 2011 to 11.3% of revenues, before fuel surcharges, during 2012. The increase relates primarily to an increase in driver lease expense as the average number of owner operators under contract increased from 48 during 2011 to 149 during 2012. The increase in costs in this category, as they relate to the increase in owner operators, are partially offset by a decrease in other cost categories, such as repairs and fuel, which are generally borne by the owner operator.

Depreciation and amortization increased from 12.8% of revenues, before fuel surcharges, during 2011 to 14.0% of revenues, before fuel surcharges, during 2012. The increase relates primarily to purchases of new trucks made during 2012 which replaced older trucks within the fleet. These new truck replacements have a significantly higher purchase price than those trucks that are being replaced and are also being depreciated over a shorter period of time as the Company accelerates its truck replacement cycle from every five years to a replacement cycle of every three years. This reduction in replacement cycle, combined with a higher purchase price, results in higher depreciation expense over a shorter period of time. The decrease in the truck replacement cycle time is intended to reduce fuel costs, improve driver and customer satisfaction, and to reduce long-term maintenance costs as well as increase fleet efficiency by reducing maintenance down-time.

Operating supplies and expenses decreased from 14.5% of revenues, before fuel surcharges, during 2011 to 14.3% of revenues, before fuel surcharges, during 2012. The decrease relates primarily to a decrease in amounts paid for equipment maintenance costs during 2012 as compared to amounts paid during 2011 as a result of replacing older equipment with new equipment. Partially offsetting this decrease was an increase in amounts paid for driver training schools during 2012 as compared to amounts paid during 2011. The increase in driver training and recruiting costs are a result of heightened competition for qualified drivers as industry demand has increased and increased regulations have forced some drivers to exit the profession.

Operating taxes and licenses decreased from 1.9% of revenues, before fuel surcharges, during 2011 to 1.8% of revenues, before fuel surcharges, during 2012. The decrease, as a percentage of revenue, resulted from the interaction of expenses with fixed-cost characteristics, such as registration fees, with an increase in revenues for the periods compared. On a dollar basis, operating taxes and licenses, which consists primarily of equipment registration fees, increased from $4.9 million during 2011 to $5.0 million during 2012.

Insurance and claims expense increased from 4.9% of revenues, before fuel surcharges, during 2011 to 5.0% of revenues, before fuel surcharges, during 2012. The increase relates primarily to an increase in auto liability and cargo related claims expenses incurred during 2012 as compared to 2011.

Other expenses decreased from 2.3% of revenues, before fuel surcharges, during 2011 to 1.9% of revenues, before fuel surcharges, during 2012. The decrease relates primarily to a decrease in amounts expensed for uncollectible revenue, professional services, and for other supplies and expenses.

The truckload services division operating ratio, which measures the ratio of operating expenses, net of fuel surcharges, to operating revenues, before fuel surcharges, decreased to 99.2% for 2012 from 102.1% for 2011.

Non-operating income increased from 0.6% of revenues, before fuel surcharges, during 2011 to 1.2% of revenues, before fuel surcharges, during 2012. The components of this category consist primarily of dividends earned and gains or losses on the Company’s investments in marketable equity securities. The increase relates primarily to an increase in the amount of dividends and capital gains recognized between the periods on the Company’s investments in marketable equity securities.

For the year ended December 31, 2013, logistics and brokerage services revenues, before fuel surcharges, decreased 5.1% to $23.0 million as compared to $24.3 million for the year ended December 31, 2012. The decrease was primarily the result of a decrease in the brokered load rates during 2013 as compared to 2012.

Salaries, wages and benefits increased from 1.8% of revenues, before fuel surcharges, in 2012 to 2.6% of revenues, before fuel surcharges, in 2013. The increase resulted from an increase in the number of employees assigned to the logistics and brokerage services division.

Rent and purchased transportation decreased from 95.2% of revenues, before fuel surcharges, in 2012 to 94.3% of revenues, before fuel surcharges, in 2013. The decrease relates to a decrease in amounts charged by third party logistics and brokerage service providers.

The logistics and brokerage services division operating ratio, which measures the ratio of operating expenses, net of fuel surcharges, to operating revenues, before fuel surcharges, remained unchanged at 97.3% for 2013 and 2012.

2012 Compared to 2011

For the year ended December 31, 2012, logistics and brokerage services revenues, before fuel surcharges, increased 32.1% to $24.3 million as compared to $18.4 million for the year ended December 31, 2011. The increase was primarily the result of an increase in the number of loads brokered during 2012 as compared to 2011.

- 28 -

Salaries, wages and benefits decreased from 1.9% of revenues, before fuel surcharges, in 2011 to 1.8% of revenues, before fuel surcharges, in 2012. The decrease, as a percentage of revenues, resulted primarily from the fixed cost characteristics of wages which do not fluctuate with changes in revenue, such as general and administrative and marketing wages. Using a dollar-based comparison, salaries, wages and benefits increased from $0.3 million during 2011 to $0.4 million during 2012 as the number of employees assigned to the logistics and brokerage services division increased.

Rent and purchased transportation decreased from 95.7% of revenues, before fuel surcharges, in 2011 to 95.2% of revenues, before fuel surcharges, in 2012. The decrease relates to a decrease in amounts charged by third party logistics and brokerage service providers.

The logistics and brokerage services division operating ratio, which measures the ratio of operating expenses, net of fuel surcharges, to operating revenues, before fuel surcharges, decreased to 97.3% for 2012 from 98.1% for 2011.

2013 Compared to 2012

Income tax expense was approximately $3.8 million in 2013 resulting in an effective rate of 38.8%, as compared to an income tax expense of approximately $1.4 million in 2012 resulting in an effective rate of 39.4%. The effective tax rate differs from the statutory rate primarily due to the existence of partially non-deductible meal and incidental expense per-diem payments to company drivers. Per-diem payments may cause a significant difference in the Company’s effective tax rate from period-to-period as the proportion of non-deductible expenses to pre-tax net income increases or decreases.

In determining whether a tax asset valuation allowance is necessary, management, in accordance with the provisions of ASC 740-10-30, weighs all available evidence, both positive and negative to determine whether, based on the weight of that evidence, a valuation allowance is necessary. If negative conditions exist which indicate a valuation allowance might be necessary, consideration is then given to what effect the future reversals of existing taxable temporary differences and the availability of tax strategies might have on future taxable income to determine the amount, if any, of the required valuation allowance. As of December 31, 2013, management determined that the future reversals of existing taxable temporary differences and available tax strategies would generate sufficient future taxable income to realize its tax assets and therefore a valuation allowance was not necessary.

As of December 31, 2013, there were no significant unrecognized tax benefits and an adjustment to the Company’s consolidated financial statements for uncertain tax positions was not required as management believes that the Company’s significant tax positions taken in income tax returns filed or to be filed are supported by clear and unambiguous income tax laws.

The Company and its subsidiaries are subject to U.S. and Canadian federal income tax laws as well as the income tax laws of multiple state jurisdictions. The major tax jurisdictions in which we operate generally provide for a deficiency assessment statute of limitation period of three years and as a result, the Company’s tax years 2010 and forward remain open to examination in those jurisdictions. During 2013, the Company has not recognized or accrued any interest or penalties related to uncertain income tax positions and does not believe it is reasonably possible that our unrecognized tax benefits will significantly change within the next twelve months.

The combined net income for all divisions was $5.9 million, or 1.9% of revenues, before fuel surcharge, for 2013 as compared to the combined net income for all divisions of $2.2 million or 0.7% of revenues, before fuel surcharge, for 2012. The increase in net income resulted in an increase in diluted earnings per share to $0.68 for 2013 from a diluted earnings per share of $0.25 for 2012.

2012 Compared to 2011

Income tax expense was approximately $1.4 million in 2012 resulting in an effective rate of 39.4%, as compared to an income tax benefit of approximately $2.7 million in 2011 resulting in an effective rate of 48.9%. The effective tax rate differs from the statutory rate primarily due to the existence of partially non-deductible meal and incidental expense per-diem payments to company drivers. Per-diem payments may cause a significant difference in the Company’s effective tax rate from period-to-period as the proportion of non-deductible expenses to pre-tax net income increases or decreases.

During 2012, the Company has not recognized or accrued any interest or penalties related to uncertain income tax positions and does not believe it is reasonably possible that our unrecognized tax benefits will significantly change within the next twelve months.

The combined net income for all divisions was $2.2 million, or 0.7% of revenues, before fuel surcharge, for 2012 as compared to the combined net loss for all divisions of $2.9 million or 1.0% of revenues, before fuel surcharge, for 2011. The increase in income resulted in an increase in diluted earnings per share to $0.25 for 2012 from a diluted loss per share of $0.32 for 2011.

Liquidity and Capital Resources

Our business has required, and will continue to require, a significant investment in new revenue equipment. Our primary sources of liquidity have been funds provided by operations, proceeds from the sales of revenue equipment, issuances of equity securities, and borrowings under our lines of credit, installment notes, and investment margin account.

During 2013, we generated $43.2 million in cash from operating activities compared to $33.6 million and $34.9 million in 2012 and 2011, respectively. Investing activities used $44.3 million in cash during 2013 compared to $72.6 million and $61.4 million in 2012 and 2011, respectively. The cash used for investing activities in all three years related primarily to the purchase of revenue equipment such as trucks and trailers or related equipment such as auxiliary power units. Financing activities provided $1.8 million in cash during 2013 compared to $39.3 million and $12.9 million in cash provided during 2012 and 2011, respectively. See the Consolidated Statements of Cash Flows in Item 8 of this Report.

Our primary use of funds is for the purchase of revenue equipment. We typically use installment notes, our existing lines of credit on an interim basis, proceeds from the sale or trade of equipment, and cash flows from operations, to finance capital expenditures and repay long-term debt. During 2013 and 2012, we utilized cash on hand, installment notes, and our lines of credit to finance revenue equipment purchases of approximately $70.2 million and $95.1 million, respectively.

Occasionally we finance the acquisition of revenue equipment through installment notes with fixed interest rates and terms ranging from 36 to 60 months. At December 31, 2013, the Company’s subsidiaries had combined outstanding indebtedness under such installment notes of $110.5 million. These installment notes are payable in monthly installments, ranging from 36 monthly installments to 60 monthly installments, at a weighted average interest rate of 2.91%. At December 31, 2012, the Company’s subsidiaries had combined outstanding indebtedness under such installment notes of $102.1 million. These installment notes were payable in 36 monthly installments at a weighted average interest rate of 3.02%.

In order to maintain our truck and trailer fleet count it is often necessary to purchase replacement units and place them in service before trade units are removed from service. The timing of this process often requires the Company to pay for new units without any reduction in price for trade units. In this situation, the Company later receives payment for the trade units as they are delivered to the equipment vendor and have passed vendor inspection. During the twelve months ended December 31, 2013 and 2012, the Company received approximately $16.3 million and $12.7 million, respectively, for units delivered for trade.

- 31 -

During 2013, the Company maintained a $35.0 million revolving line of credit. Amounts outstanding under the line bear interest at LIBOR (determined as of the first day of each month) plus 1.75% (1.92% at December 31, 2013), are secured by our trade accounts receivable and mature on June 1, 2015. At December 31, 2013, outstanding advances on the line were approximately $1.1 million, which consisted entirely of letters of credit totaling $1.1 million, with availability to borrow $33.9 million.

Trade accounts receivable increased from $50.0 million at December 31, 2012 to $58.5 million at December 31, 2013. The increase relates to a general increase in freight revenue and fuel surcharge revenue, which flows through the accounts receivable account, during 2013 as compared to the freight revenue and fuel surcharge revenue generated during 2012.

Marketable equity securities at December 31, 2013 increased approximately $3.7 million as compared to December 31, 2012. The increase was primarily related to changes in market value of approximately $3.1 million and to purchases of new securities of approximately $0.9 million partially offset by the cost of securities sold of approximately $0.3 million. At December 31, 2013, the remaining marketable equity securities have a combined cost basis of approximately $11.0 million and a combined fair market value of approximately $21.0 million. The Company has developed a strategy to invest in securities from which it expects to receive dividends that qualify for favorable tax treatment, as well as appreciate in value. The Company anticipates that increases in the market value of the investments combined with dividend payments will exceed interest rates paid on borrowings for the same period. During 2013, the Company had net unrealized pre-tax gains of approximately $3.1 million and received dividends of approximately $0.8 million. The holding term of these securities depends largely on the general economic environment, the equity markets, borrowing rates and the Company's cash requirements.

Revenue equipment, at December 31, 2013, which generally consists of trucks, trailers, and revenue equipment accessories such as Qualcomm™ satellite tracking units and auxiliary power units, decreased approximately $9.3 million as compared to December 31, 2012. The decrease relates primarily to a decrease in the number of company-owned trucks from 1,580 at December 31, 2012 to 1,480 at December 31, 2013.

Accounts payable at December 31, 2013 increased approximately $8.9 million as compared to December 31, 2012. The increase was primarily related to an accrual at December 31, 2013 for the purchase of treasury stock through a Dutch Auction in the amount of $13.9 million which was partially offset by a decrease in amounts accrued for the purchase of revenue equipment of approximately $2.2 million at December 31, 2013 compared to December 31, 2012 and by a decrease in bank drafts outstanding in excess of the bank balance of approximately $1.6 million at December 31, 2013 as compared to December 31, 2013.

Accrued expenses and other liabilities at December 31, 2013 increased approximately $1.2 million as compared to December 31, 2012. The increase is primarily related to a $0.9 million increase in amounts accrued for workers’ compensation claims and a $0.7 million increase in amounts accrued for owner operators. These increases were offset by a $0.7 million reduction in margin account borrowings which are secured by the Company’s investments in marketable equity securities. The Company periodically uses this margin account for the purchase of marketable equity securities and as a source of short-term liquidity.

Current maturities of long term-debt and long-term debt fluctuations are reviewed on an aggregate basis as the classification of amounts in each category are typically affected merely by the passage of time. Current maturities of long-term debt and long-term debt, on an aggregate basis at December 31, 2013, increased approximately $3.0 million as compared to December 31, 2012. The increase was related to additional borrowings received during 2013 net of the principal portion of scheduled installment note payments made during 2013.

For 2014, we expect to purchase 300 new trucks and 720 new trailers while continuing to sell or trade equipment that has reached the end of its cycle, which we expect to result in net capital expenditures of approximately $16.9 million. Management believes we will be able to finance our near term needs for working capital over the next twelve months, as well as acquisitions of revenue equipment during such period, with cash balances, cash flows from operations, and borrowings believed to be available from financing sources. We will continue to have significant capital requirements over the long-term, which may require us to incur debt or seek additional equity capital. The availability of additional capital will depend upon prevailing market conditions, the market price of our common stock and several other factors over which we have limited control, as well as our financial condition and results of operations. Nevertheless, based on our anticipated future cash flows and sources of financing that we expect will be available to us, we do not expect that we will experience any significant liquidity constraints in the foreseeable future.

Insurance

With respect to physical damage for trucks and trailers, cargo loss, and auto liability, the Company maintains insurance coverage to protect it from certain business risks. These policies are with various carriers and have per occurrence deductibles of $2,500, $10,000 and $2,500 respectively. The Company maintains workers’ compensation coverage in Arkansas, Ohio, Oklahoma, Mississippi, and Florida with a $500,000 self-insured retention and a $500,000 per occurrence excess policy. The Company has elected to opt out of workers' compensation coverage in Texas and is providing coverage through the P.A.M. Texas Injury Plan. The Company has reserved for estimated losses to pay such claims as well as claims incurred but not yet reported. The Company has not experienced any adverse trends involving differences in claims experienced versus claims estimates for workers’ compensation claims. Letters of credit aggregating approximately $1,101,000 and certificates of deposit totaling $300,000 are held by banks as security for workers’ compensation claims. The Company self insures for employee health claims with a stop loss of $275,000 per covered employee per year and estimates its liability for claims incurred but not reported.

Inflation

Inflation has an impact on most of our operating costs. Over the past three years, the effect of inflation has been minimal.

Adoption of Accounting Policies

See “Item 8. Financial Statements and Supplementary Data, Note 1 to the Consolidated Financial Statements - Recent Accounting Pronouncements.”

- 33 -

Critical Accounting Policies

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to adopt accounting policies and make significant judgments and estimates 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 judgments and estimates. In many cases, there are alternative assumptions, policies, or estimation techniques that could be used. Management evaluates its assumptions, policies, and estimates on an ongoing basis, utilizing historical experience, 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 would be reported using differing estimates or assumptions. Management considers our critical accounting policies to be those that require more significant judgments and estimates when we prepare our consolidated financial statements. Our critical accounting policies include the following:

Accounts receivable and allowance for doubtful accounts. Accounts receivable are presented in the Company’s consolidated financial statements net of an allowance for estimated uncollectible amounts. Management estimates this allowance based upon an evaluation of the aging of our customer receivables and historical write-offs, as well as other trends and factors surrounding the credit risk of specific customers. The Company continually updates the history it uses to make these estimates so as to reflect the most recent trends, factors and other information available. In order to gather information regarding these trends and factors, the Company also performs ongoing credit evaluations of its customers. Customer receivables are considered to be past due when payment has not been received by the invoice due date. Write-offs occur when we determine an account to be uncollectible and could differ from the allowance estimate as a result of a number of factors, including unanticipated changes in the overall economic environment or factors and risks surrounding a particular customer. Management believes its methodology for estimating the allowance for doubtful accounts to be reliable however, additional allowances may be required if the financial condition of our customers were to deteriorate and could have a material effect on the Company’s consolidated financial statements.

Depreciation of trucks and trailers. Depreciation of trucks and trailers is calculated by the straight-line method over the assets estimated useful life, which range from three to 12 years, down to an estimated salvage value at the end of the assets estimated useful life. Management must use its judgment in the selection of estimated useful lives and salvage values for purposes of this calculation. In some cases, the Company has agreements in place with certain manufacturers whereby salvage values are guaranteed by the manufacturer. In other cases, where salvage values are not guaranteed, estimates of salvage value are based on the expected market values of equipment at the time of disposal.

The depreciation of trucks and trailers over their estimated useful lives and the determination of any salvage value also require management to make judgments about future events. Therefore, the Company’s management periodically evaluates whether changes to estimated useful lives or salvage values are necessary to ensure these estimates accurately reflect the economic reality of the assets. This periodic evaluation may result in changes in the estimated lives and/or salvage values used by the Company to depreciate its assets, which can affect the amount of periodic depreciation expense recognized and, ultimately, the gain or loss on the disposal of an asset. Future changes in our estimated useful life or salvage value estimates, or fluctuations in market value that is not reflected in current estimates, could have a material effect on the Company’s consolidated financial statements.

Impairment of long-lived assets. Long-lived assets are reviewed for impairment in accordance with Topic ASC 360, “Property, Plant, and Equipment”. This authoritative guidance provides that whenever there are certain significant events or changes in circumstances the value of long-lived assets or groups of assets must be tested to determine if their value can be recovered from their future cash flows. In the event that undiscounted cash flows expected to be generated by the asset are less than the carrying amount, the asset or group of assets must be evaluated for impairment. Impairment exists if the carrying value of the asset exceeds its fair value.

- 34 -

Significantly all of the Company’s cash flows from operations are generated by trucks and trailers, and as such, the cost of other long-lived assets are funded by those operations. Therefore, management tests for the recoverability of all of the Company’s long-lived assets as a single group at the entity level and examines the forecasted future cash flows generated by trucks and trailers, including their eventual disposition, to determine if those cash flows exceed the carrying value of the long-lived assets. Forecasted cash flows are estimated using assumptions about future operations. To the extent that facts and circumstances change in the future, our estimates of future cash flows may also change either positively or negatively. In light of the increase in the Company’s market capitalization during 2013 and net operating profits of the Company for the years ended December 31, 2013 and 2012, no impairment indicators existed which required management to test the Company’s long-lived assets for recoverability as of December 31, 2013. As such, no impairment losses were recorded during 2013.

Claims accruals. The Company is self-insured for health and workers' compensation benefits up to certain stop-loss limits. Such costs are accrued based on known claims and an estimate of incurred, but not reported (IBNR) claims. IBNR claims are estimated using historical lag information and other data either provided by outside claims administrators or developed internally. Actual claims payments may differ from management’s estimates as a result of a number of factors, including evaluation of severity, increases in legal or medical costs, and other case-specific factors. The actual claims payments are charged against the Company’s recorded accrued claims liabilities and have been reasonable with respect to the estimates of the liabilities made under the Company’s methodology. However, the estimation process is generally subjective, and to the extent that future actual results materially differ from original estimates made by management, adjustments to recorded accruals may be necessary which could have a material effect on the Company’s consolidated financial statements. Based upon our 2013 health and workers' compensation expenses, a 10% increase in both claims incurred and claims incurred but not reported, would increase our annual health and workers' compensation expenses by $1.0 million.

Revenue recognition. Revenue is recognized in full upon completion of delivery to the receiver's location. For freight in transit at the end of a reporting period, the Company recognizes revenue pro rata based on relative transit time completed as a portion of the estimated total transit time. Expenses are recognized as incurred.

Income Taxes. The Company’s deferred tax assets and liabilities represent items that will result in taxable income or a tax deduction in future years for which the Company has already recorded the related tax expense or benefit in its consolidated statements of operations. Deferred tax accounts arise as a result of timing differences between when items are recognized in the Company’s consolidated financial statements compared to when they are recognized in the Company’s tax returns. In establishing the Company’s deferred income tax assets and liabilities, management makes judgments and interpretations based on the enacted tax laws and published tax guidance that are applicable to its operations. Deferred income 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.

In determining whether a tax asset valuation allowance is necessary, management, in accordance with the provisions of ASC 740-10-30, weighs all available evidence, both positive and negative to determine whether, based on the weight of that evidence, a valuation allowance is necessary. If negative conditions exist which indicate a valuation allowance might be necessary, consideration is then given to what effect the future reversals of existing taxable temporary differences and the availability of tax strategies might have on future taxable income to determine the amount, if any, of the required valuation allowance. Significant management judgment is required as it relates to future taxable income, future capital gains, tax settlements, valuation allowances, and the Company’s ability to utilize tax loss and credit carryforwards. As of December 31, 2013, management determined that the future reversals of existing taxable temporary differences and available tax strategies would generate sufficient future taxable income to realize its tax assets and therefore a valuation allowance was not necessary.

Management believes that future tax consequences have been adequately provided for based on the current facts and circumstances and current tax law. However, should current circumstances change or the Company’s tax positions be challenged, different outcomes could result which could have a material effect on the Company’s consolidated financial statements.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk.

Our primary market risk exposures include equity price risk, interest rate risk, commodity price risk (the price paid to obtain diesel fuel for our trucks), and foreign currency exchange rate risk. The potential adverse impact of these risks are discussed below.

The following sensitivity analyses do not consider the effects that an adverse change may have on the overall economy nor do they consider additional actions we may take to mitigate our exposure to such changes. Actual results of changes in prices or rates may differ materially from the hypothetical results described below.

Equity Price Risk

We hold certain actively traded marketable equity securities which subjects the Company to fluctuations in the fair market value of its investment portfolio based on current market price. The recorded value of marketable equity securities increased to $21.0 million at December 31, 2013 from $17.3 million at December 31, 2012. The increase includes an increase in fair market value, net of write-downs, of approximately $3.1 million, additional purchases of $0.9 million, sales of $0.3 million, and return of capital proceeds of $0.1 million during 2013. A 10% decrease in the market price of our marketable equity securities would cause a corresponding 10% decrease in the carrying amounts of these securities, or approximately $2.1 million. For additional information with respect to the marketable equity securities, see Note 3 to our consolidated financial statements.

Interest Rate Risk

Our line of credit bears interest at a floating rate equal to LIBOR plus a fixed percentage. Accordingly, changes in LIBOR, which are affected by changes in interest rates, will affect the interest rate on, and therefore our costs under, the line of credit. Assuming $1.0 million of variable rate debt was outstanding under our line of credit for a full fiscal year, a hypothetical 100 basis point increase in LIBOR would result in approximately $10,000 of additional interest expense.

Commodity Price Risk

Prices and availability of all petroleum products are subject to political, economic and market factors that are generally outside of our control. Accordingly, the price and availability of diesel fuel, as well as other petroleum products, can be unpredictable. Because our operations are dependent upon diesel fuel, significant increases in diesel fuel costs could materially and adversely affect our results of operations and financial condition. Based upon our 2013 fuel consumption, a 10% increase in the average annual price per gallon of diesel fuel would increase our annual fuel expenses by approximately $9.8 million.

Foreign Currency Exchange Rate Risk

We are exposed to foreign currency exchange rate risk related to the activities of our branch office located in Mexico. Currently, we do not hedge our exchange rate exposure through any currency forward contracts, currency options, or currency swaps as all of our revenues, and substantially all of our expenses and capital expenditures, are transacted in U.S. dollars. However, certain operating expenditures and capital purchases related to our Mexico branch office are incurred within or exposed to fluctuations in the exchange rate between the U.S. Dollar and the Mexican peso. Based on 2013 expenditures denominated in pesos, a 10% increase in the exchange rate would increase our annual operating expenses by approximately $63,000.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

P.A.M. Transportation Services, Inc.

We have audited the accompanying consolidated balance sheets of P.A.M. Transportation Services, Inc. (a Delaware corporation) and subsidiaries (the “Company”) as of December 31, 2013 and 2012, and the related consolidated statements of operations, comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2013. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these 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 P.A.M. Transportation Services, Inc. and subsidiaries as of December 31, 2013 and 2012, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2013 in conformity with accounting principles generally accepted in the United States of America.

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, 2013, based on criteria established in the 1992 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated March 14, 2014 expressed an unqualified opinion thereon.

P.A.M. TransportATION SERVICES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

YEARS ENDED DECEMBER 31, 2013, 2012 AND 2011

1.     ACCOUNTING POLICIES

Description of Business and Principles of Consolidation–P.A.M. Transportation Services, Inc. (the “Company”), through its subsidiaries, operates as a truckload transportation and logistics company.

The consolidated financial statements include the accounts of the Company and its wholly owned operating subsidiaries: P.A.M. Transport, Inc., P.A.M. Cartage Carriers, LLC, Overdrive Leasing, LLC, Choctaw Express, LLC, Decker Transport Co., LLC, T.T.X., LLC, Transcend Logistics, Inc., and East Coast Transport and Logistics, LLC. The following subsidiaries were inactive during all periods presented: P.A.M. International, Inc., P.A.M. Logistics Services, Inc., Choctaw Brokerage, Inc., P.A.M. Canada, Inc. and S & L Logistics, Inc.

Use of Estimates–The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of any contingent assets and liabilities at the financial statement date and reported amounts of revenue and expenses during the reporting period. The Company periodically reviews these estimates and assumptions. The Company's estimates were based on its historical experience and various other assumptions that the Company believes to be reasonable under the circumstances. Actual results could differ from those estimates.

Cash and Cash Equivalents–The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.

Accounts Receivable and Allowance for Doubtful Accounts–Accounts receivable are presented in the Company’s consolidated financial statements net of an allowance for estimated uncollectible amounts. Management estimates this allowance based upon an evaluation of the aging of our customer receivables and historical write-offs, as well as other trends and factors surrounding the credit risk of specific customers. The Company continually updates the history it uses to make these estimates so as to reflect the most recent trends, factors and other information available. In order to gather information regarding these trends and factors, the Company also performs ongoing credit evaluations of its customers. Customer receivables are considered to be past due when payment has not been received by the invoice due date. Write-offs occur when we determine an account to be uncollectible and could differ from the allowance estimate as a result of a number of factors, including unanticipated changes in the overall economic environment or factors and risks surrounding a particular customer. Management believes its methodology for estimating the allowance for doubtful accounts to be reliable however, additional allowances may be required if the financial condition of our customers were to deteriorate, and could have a material effect on the Company’s consolidated financial statements.

- 45 -

Bank Overdrafts–The Company classifies bank overdrafts in current liabilities as an accounts payable and does not offset other positive bank account balances located at the same or other financial institutions. Bank overdrafts generally represent checks written that have not yet cleared the Company’s bank accounts. The majority of the Company’s bank accounts are zero balance accounts that are funded at the time items clear against the account by drawings against a line of credit, therefore the outstanding checks represent bank overdrafts. Because the recipients of these checks have generally not yet received payment, the Company continues to classify bank overdrafts as accounts payable. Bank overdrafts are classified as changes in accounts payable in the cash flows from operating activities section of the Company’s Consolidated Statement of Cash Flows. Bank overdrafts as of December 31, 2013 and 2012 were approximately $3,179,000 and $4,803,000, respectively.

Accounts Receivable Other–The components of accounts receivable other consist primarily of amounts representing company driver advances, owner-operator advances, equipment manufacturer warranties, and restricted cash. Advances receivable from company drivers as of December 31, 2013 and 2012, were approximately $707,000 and $882,000, respectively. Restricted cash consists of cash proceeds from the sale of trucks and trailers under our like-kind exchange (“LKE”) tax program. See Note 11, “Federal and State Income Taxes,” for a discussion of the Company’s LKE tax program. We classify restricted cash as a current asset within “Accounts receivable-other” as the exchange process must be completed within 180 days in order to qualify for income tax deferral treatment. The changes in restricted cash balances are reflected as an investing activity in our Consolidated Statements of Cash Flows as they relate to the sales and purchases of revenue equipment.

Marketable Equity Securities–Marketable equity securities are classified by the Company as either available for sale or trading. Securities classified as available for sale are carried at market value with unrealized gains and losses recognized in accumulated other comprehensive income in the statements of stockholders’ equity. Securities classified as trading are carried at market value with unrealized gains and losses recognized in the statements of operations. Realized gains and losses are computed utilizing the specific identification method.

Impairment of Long-Lived Assets–The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset may not be recoverable. An impairment loss would be recognized if the carrying amount of the long-lived asset is not recoverable, and it exceeds its fair value. For long-lived assets classified as held and used, if the carrying value of the long-lived asset exceeds the sum of the future net cash flows, it is not recoverable.

Property and Equipment–Property and equipment is recorded at historical cost, less accumulated depreciation. For financial reporting purposes, the cost of such property is depreciated principally by the straight-line method. For tax reporting purposes, accelerated depreciation or applicable cost recovery methods are used. Depreciation is recognized over the estimated asset life, considering the estimated salvage value of the asset. Such salvage values are based on estimates using expected market values for used equipment and the estimated time of disposal which, in many cases include guaranteed residual values by the manufacturers. Gains and losses are reflected in the year of disposal. The following is a table reflecting estimated ranges of asset useful lives by major class of depreciable assets:

Asset Class	Estimated Asset Life
Service vehicles (years)	3	-	5
Office furniture and equipment (years)	3	-	7
Revenue equipment (years)	3	-	12
Structure and improvements (years)	5	-	40

The Company’s management periodically evaluates whether changes to estimated useful lives and/or salvage values are necessary to ensure its estimates accurately reflect the economic use of the assets. During 2013, management adjusted the estimated useful lives and salvage values of certain trucks based on such an evaluation. These changes resulted in a decrease in depreciation expense of approximately $550,000 during 2013. This reduction in depreciation expense increased the Company’s 2013 reported net income by approximately $340,000 ($0.04 per diluted share).

- 46 -

During 2012, management adjusted the estimated useful lives and salvage values of certain trucks based on such an evaluation. These changes resulted in a decrease in depreciation expense of approximately $450,000 during 2012. This reduction in depreciation expense increased the Company’s 2012 reported net income by approximately $300,000 ($0.03 per diluted share).

During 2011, management decreased the estimated useful lives and adjusted the salvage values of certain trucks which were expected to be traded for newer model trucks. These changes resulted in additional depreciation expense of approximately $4,200,000 during 2011. This additional depreciation expense increased the Company’s 2011 reported net loss by approximately $2,600,000 ($0.29 per diluted share).

Prepaid Tires–Tires purchased with revenue equipment are capitalized as a cost of the related equipment. Replacement tires are included in prepaid expenses and deposits and are amortized over a 24-month period. Amounts paid for the recapping of tires are expensed when incurred.

Advertising Expense–Advertising costs are expensed as incurred and totaled approximately $662,000, $685,000 and $437,000 for the years ended December 31, 2013, 2012 and 2011, respectively.

Classification of Owner/Operator Expense – In order to conform to industry practice, the Company began to classify payments to third-party owner operator drivers as purchased transportation rather than as salaries, wages and benefits as had been presented in reports prior to the period ended September 30, 2013. This reclassification has no effect on operating income, net income or earnings per share. The Company has made corresponding reclassifications to comparative periods shown.

Repairs and Maintenance–Repairs and maintenance costs are expensed as incurred.

Self Insurance Liability–A liability is recognized for known health, workers’ compensation, cargo damage, property damage and auto liability damage claims. An estimate of the incurred but not reported claims for each type of liability is made based on historical claims made, estimated frequency of occurrence, and considering changing factors that contribute to the overall cost of insurance.

Income Taxes–The Company applies the asset and liability method of accounting for income taxes, under which deferred taxes are determined based on the temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the basis differences reverse. A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized.

The application of income tax law to multi-jurisdictional operations such as those performed by the Company, are inherently complex. Laws and regulations in this area are voluminous and often ambiguous. As such, we may be required to make subjective assumptions and judgments regarding our income tax exposures. Interpretations of and guidance surrounding income tax laws and regulations may change over time which could cause changes in our assumptions and judgments that could materially affect amounts recognized in the consolidated financial statements.

We recognize the impact of tax positions in our financial statements. These tax positions must meet a more-likely-than-not recognition threshold to be recognized and tax positions that previously failed to meet the more-likely-than-not threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not threshold are derecognized in the first subsequent financial reporting period in which that threshold is no longer met. We recognize potential accrued interest and penalties related to unrecognized tax benefits within the consolidated statements of income as income tax expense.

- 47 -

In determining whether a tax asset valuation allowance is necessary, management, in accordance with the provisions of ASC 740-10-30, weighs all available evidence, both positive and negative to determine whether, based on the weight of that evidence, a valuation allowance is necessary. If negative conditions exist which indicate a valuation allowance might be necessary, consideration is then given to what effect the future reversals of existing taxable temporary differences and the availability of tax strategies might have on future taxable income to determine the amount, if any, of the required valuation allowance. As of December 31, 2013, management determined that the future reversals of existing taxable temporary differences and available tax strategies would generate sufficient future taxable income to realize its tax assets and therefore a valuation allowance was not necessary.

Revenue Recognition–Revenue is recognized in full upon completion of delivery to the receiver’s location. For freight in transit at the end of a reporting period, the Company recognizes revenue pro rata based on relative transit time completed as a portion of the estimated total transit time. Expenses are recognized as incurred.

Share-Based Compensation–The Company estimates the fair value of stock option awards on the option grant date using the Black-Scholes pricing model and recognizes compensation for stock option awards expected to vest on a straight-line basis over the requisite service period for the entire award. Forfeitures are estimated at grant date based on historical experience. For additional information with respect to share-based compensation, see Note 12 to our consolidated financial statements.

Earnings Per Share–The Company computes basic earnings per share (“EPS”) by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS includes the potential dilution that could occur from stock-based awards and other stock-based commitments using the treasury stock or the as if converted methods, as applicable. The difference between the Company's weighted-average shares outstanding and diluted shares outstanding is due to the dilutive effect of stock options for all periods presented. See Note 13 for computation of diluted EPS.

Fair Value Measurements–Certain financial assets and liabilities are measured at fair value within the financial statements on a recurring basis. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. For additional information with respect to fair value measurements, see Note 16 to our consolidated financial statements.

Reporting Segments–The Company's operations are all in the motor carrier segment and are aggregated into a single reporting segment in accordance with the aggregation criteria under Generally Accepted Accounting Principles (“GAAP”). The Company provides truckload transportation services as well as brokerage and logistics services to customers throughout the United States and portions of Canada and Mexico. Truckload transportation services revenues, excluding fuel surcharges, represented 92.6%, 91.8% and 93.5% of total revenues, excluding fuel surcharges, for the twelve months ended December 31, 2013, 2012 and 2011, respectively. Remaining revenues, excluding fuel surcharges, for each respective year were generated by brokerage and logistics services.

Concentrations of Credit Risk–The Company performs ongoing credit evaluations and generally does not require collateral from its customers. The Company maintains reserves for potential credit losses. In view of the concentration of the Company’s revenues and accounts receivable among a limited number of customers within the automobile industry, the financial health of this industry is a factor in the Company’s overall evaluation of accounts receivable.

- 48 -

Subsequent Events–We have evaluated subsequent events for recognition and disclosure through the date these financial statements were filed with the United States Securities and Exchange Commission and concluded that no subsequent events or transactions have occurred that require recognition or disclosure in our financial statements.

Foreign Currency Transactions– The functional currency of the Company’s foreign branch office in Mexico is the U.S. dollar. The Company remeasures the monetary assets and liabilities of this branch office, which are maintained in the local currency ledgers, at the rates of exchange in effect at the end of the reporting period. Revenues and expenses recorded in the local currency during the period are remeasured using average exchange rates for each period. Non-monetary assets and liabilities are remeasured using historical rates. Any resulting exchange gain or loss from the remeasurement process are included in non-operating income in the Company’s consolidated statements of operations.

Recent Accounting Pronouncements– In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) No. 2013-2, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. This guidance requires an organization to present the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income (“OCI”), but only if the item reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. The guidance is effective for fiscal years beginning after December 15, 2012. The adoption of this guidance on January 1, 2013 did not have a significant impact on the Company’s financial condition, results of operations, or cash flow.

In December 2011, the FASB issued ASU No. 2011-11, Disclosures about Offsetting Assets and Liabilities, which requires entities to disclose both gross and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting agreement. The objective of the disclosure is to facilitate comparison between those entities that prepare their financial statements on the basis of U.S. GAAP and those entities that prepare their financial statements on the basis of International Financial Reporting Standards. Retrospective presentation for all comparative periods presented is required. This ASU is effective for fiscal years, and interim periods within those years, beginning on or after January 1, 2013. The adoption of this guidance on January 1, 2013 did not have a material effect on the Company’s financial condition, results of operations, or cash flow.

2.     TRADE ACCOUNTS RECEIVABLE

The Company's receivables result primarily from the sale of transportation and logistics services. The Company performs ongoing credit evaluations of its customers and generally does not require collateral for accounts receivable.

3.     MARKETABLE EQUITY SECURITIES

The Company accounts for its marketable securities in accordance with ASC Topic 320, Investments-Debt and Equity Securities. ASC Topic 320 requires companies to classify their investments as trading, available-for-sale or held-to-maturity. The Company’s investments in marketable securities are classified as either trading or available-for-sale and consist of equity securities. Management determines the appropriate classification of these securities at the time of purchase and re-evaluates such designation as of each balance sheet date. The cost of securities sold is based on the specific identification method and interest and dividends on securities are included in non-operating income.

Marketable equity securities classified as available-for-sale are carried at fair value, with the unrealized gains and losses, net of tax, included as a component of accumulated other comprehensive income in stockholders’ equity. Realized gains and losses, declines in value judged to be other-than-temporary on available-for-sale securities, and increases or decreases in value on trading securities, if any, are included in the determination of net income. A quarterly evaluation is performed in order to judge whether declines in value below cost should be considered temporary and when losses are deemed to be other-than-temporary. Several factors are considered in this evaluation process including the severity and duration of the decline in value, the financial condition and near-term outlook for the specific issuer and the Company’s ability to hold the securities.

For the years ended December 31, 2013, 2012 and 2011, the evaluation resulted in an impairment charges of approximately $29,000, $70,000 and $315,000, respectively, being reported in the Company’s non-operating income in its statement of operations.

7.     CAPITAL STOCK

The Company's authorized capital stock consists of 40,000,000 shares of common stock, par value $.01 per share, and 10,000,000 shares of preferred stock, par value $.01 per share. At December 31, 2013, there were 11,391,464 shares of our common stock issued and 7,983,539 shares outstanding. No shares of our preferred stock were issued or outstanding at December 31, 2013.

Common Stock

The holders of our common stock, subject to such rights as may be granted to any preferred stockholders, elect all directors and are entitled to one vote per share. All shares of common stock participate equally in dividends when and as declared by the Board of Directors and in net assets on liquidation. The shares of common stock have no preference, conversion, exchange, preemptive or cumulative voting rights.

Preferred Stock

Preferred stock may be issued from time to time by our Board of Directors, without stockholder approval, in such series and with such preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends, qualifications or other provisions, as may be fixed by the Board of Directors in the resolution authorizing their issuance. The issuance of preferred stock by the Board of Directors could adversely affect the rights of holders of shares of common stock; for example, the issuance of preferred stock could result in a class of securities outstanding that would have certain preferences with respect to dividends and in liquidation over the common stock, and that could result in a dilution of the voting rights, net income per share and net book value of the common stock. As of December 31, 2013, we have no agreements or understandings for the issuance of any shares of preferred stock.

Treasury Stock

In November 2010, our Board of Directors authorized the repurchase of up to 500,000 shares of our common stock during the twelve month period following the announcement. All 500,000 shares were repurchased under this repurchase authorization prior to the authorization expiration date.

The Company repurchased a total of 50,325 shares of its common stock under this authorization during 2013.

In November 2013, our Board of Directors authorized the repurchase of up to 600,000 shares of our common stock through a Dutch auction tender offer (the “tender offer”).

The tender offer began on the date of the announcement, December 2, 2013 and expired on December 30, 2013. Through the tender offer, the Company’s shareholders had the opportunity to tender some or all of their shares at a price within the range of $19.00 to 21.00 per share. Upon expiration, 675,000 shares were tendered through the offer at a final purchase price of $20.50 per share for a total purchase price of approximately $13.9 million, including fees and commission and was settled on January 6, 2014.

The Company has alternative minimum tax credits of approximately $318,000 at December 31, 2013, which have no expiration date under the current federal income tax laws and general business credits of approximately $988,000 which begin to expire after the year 2030. The Company also has net operating loss carryovers for federal income purposes of approximately $55,994,000 which begin to expire after the year 2030.

In determining whether a tax asset valuation allowance is necessary, management, in accordance with the provisions of ASC 740-10-30, weighs all available evidence, both positive and negative to determine whether, based on the weight of that evidence, a valuation allowance is necessary. If negative conditions exist which indicate a valuation allowance might be necessary, consideration is then given to what effect the future reversals of existing taxable temporary differences and the availability of tax strategies might have on future taxable income to determine the amount, if any, of the required valuation allowance. As of December 31, 2013, management determined that the future reversals of existing taxable temporary differences and available tax strategies would generate sufficient future taxable income to realize its tax assets and therefore a valuation allowance was not necessary.

The Company does not have any material accrued interest or penalties associated with any unrecognized tax benefits. The Company's policy is to account for interest and penalties related to uncertain tax positions, if any, in income tax expense. The Company did not have any unrecognized tax benefits at December 31, 2013 or December 31, 2012 and there was no change in total gross unrecognized tax benefit liabilities for the year ended December 31, 2013.

The Company and its subsidiaries are subject to U.S. and Canadian federal income tax laws as well as the income tax laws of multiple state jurisdictions. The major tax jurisdictions in which the Company operates generally provide for a deficiency assessment statute of limitation period of three years and as a result, the Company’s tax years 2010 and forward remain open to examination in those jurisdictions.

During 2007, the Company contracted with a third-party qualified intermediary in order to implement a like-kind exchange tax program. Under the program, dispositions of eligible trucks or trailers and acquisitions of replacement trucks or trailers are made in a form whereby any associated tax gains related to the disposal are deferred. To qualify for like-kind exchange treatment, we exchange, through our qualified intermediary, eligible trucks or trailers being disposed with trucks or trailers being acquired that allows us to generally carryover the tax basis of the trucks or trailers sold. The program is expected to result in a significant deferral of federal and state income taxes. Under the program, the proceeds from the sale of eligible trucks or trailers carry a Company-imposed restriction for the acquisition of replacement trucks or trailers. These proceeds may be disqualified under the program at any time and at the Company’s sole discretion, however income tax deferral would not be available for any sale for which the Company disqualifies the related proceeds. At December 31, 2013, the Company had $623,000 of restricted cash held by the third-party qualified intermediary. At December 31, 2012, the Company had $503,000 of restricted cash held by the third-party qualified intermediary. Restricted cash is accounted for in “Accounts receivable-other”.

12.   STOCK-BASED COMPENSATION

The Company maintains a stock option plan under which incentive stock options and nonqualified stock options may be granted. On March 2, 2006, the Company’s Board of Director’s adopted, and stockholders later approved, the 2006 Stock Option Plan (the “2006 Plan”). The 2006 Plan replaced the expired 1995 Stock Option Plan which had 263,500 options remaining which were never issued. Under the 2006 Plan 750,000 shares were reserved for the issuance of stock options to directors, officers, key employees and others. The option exercise price under the 2006 Plan is the fair market value of the stock on the date the option is granted. The fair market value is determined by the average of the highest and lowest sales prices for a share of the Company’s common stock, on its primary exchange, on the same date that the option is granted.

Outstanding nonqualified stock options at December 31, 2013, must be exercised within either five or ten years from the date of grant. Nonqualified stock options granted to members of the Company’s Board of Directors vest immediately while nonqualified stock options issued to employees vest in increments of 20% each year. During 2013, nonqualified options for 35,000 shares were issued to members of the Company’s Board of Directors under the 2006 Plan at an option exercise price of $10.44 per share. At December 31, 2013, 366,000 shares were available for granting future options.

Also, during 2013 the Compensation Committee of the Board of Directors granted 9,500 restricted shares of the Company’s stock to certain key employees. This restricted stock award has a grant date fair value of $18.17, based on the closing price of the Company’s stock on the date of grant, and vests in increments of 20% each year.

In May 2012, the Company granted to certain key employees, 104,000 nonqualified stock options. The exercise price for these awards was fixed at the grant date and was equal to the fair market value of the stock on that date. These nonqualified stock options vest in increments of 20% each year.

In November 2010, the Company granted to certain key employees, 50,000 nonqualified stock options and 64,000 performance-based variable nonqualified stock options. The exercise price for these awards was fixed at the grant date and was equal to the fair market value of the stock on that date. The nonqualified stock options vest in increments of 20% each year. The performance-based nonqualified stock options were eligible to be earned in four quarterly installments and one annual installment with vesting to occur in increments of 20% each year for any options earned. In order to meet the performance criteria, certain quarterly and annual “operating ratio” results must have been achieved during 2011. During 2011, 4,442 performance-based variable nonqualified stock options were earned with vesting to begin during the third quarter of 2012. The remaining 59,558 performance-based variable nonqualified stock options expired as the related performance criteria was not met.

The grant date fair value of options vested during 2013, 2012 and 2011 was approximately $346,000, $268,000 and $162,000, respectively. No restricted shares vested during any of the years presented. Total pre-tax stock-based compensation expense, recognized in Salaries, wages and benefits was approximately $317,000 during 2013 and includes approximately $179,000 as a result of the increased annual grant of 5,000 shares to each non-employee director during 2013. The Company recognized a total income tax benefit of approximately $123,000 related to stock-based compensation expense during 2013. The recognition of stock-based compensation expense decreased diluted earnings per common share and basic earnings per common share by approximately $0.02 and $0.03, respectively during 2013. As of December 31, 2013, the Company had stock-based compensation plans with total unvested stock-based compensation expense of approximately $518,000 which is being amortized on a straight-line basis over the remaining vesting period. As a result, the Company expects to recognize approximately $156,000 in additional compensation expense related to unvested option awards during 2014, $151,000 in additional compensation expense related to unvested option awards during 2015, $120,000 in additional compensation expense related to unvested option awards during 2016, $62,000 in additional compensation expense related to unvested option awards during 2017 and $29,000 in additional compensation expense related to unvested option awards during 2018.

Total pre-tax stock-based compensation expense, recognized in Salaries, wages and benefits was approximately $352,000 during 2012 and included approximately $199,000 recognized as a result of the annual grant of 5,000 shares to each non-employee director during the first quarter of 2012. The Company recognized a total income tax benefit of approximately $139,000 related to stock-based compensation expense during 2012. The recognition of stock-based compensation expense decreased diluted and basic income per common share by approximately $0.02 during 2012. At December 31, 2012, the Company had stock-based compensation plans with total unvested stock-based compensation expense of approximately $749,000.

Total pre-tax stock-based compensation expense, recognized in Salaries, wages and benefits was approximately $164,000 during 2011 and included approximately $98,000 recognized as a result of the annual grant of 2,000 shares to each non-employee director during the first quarter of 2011. The Company recognized a total income tax benefit of approximately $80,000 related to stock-based compensation expense during 2011. The recognition of stock-based compensation expense increased diluted and basic loss per common share by approximately $0.01 during 2011. At December 31, 2011, the Company had stock-based compensation plans with total unvested stock-based compensation expense of approximately $272,000.

Transactions in stock options under these plans are summarized as follows:

The fair value of the Company’s stock options was estimated at the date of grant using a Black-Scholes-Merton (“BSM”) option-pricing model using the following assumptions:

	2013		2012				2011
Dividend yield		0%			0%			0%
Volatility range		62.69%		57.88%	—	65.89%		65.81%
Risk-free rate range		0.61%		0.64%	—	1.09%		1.79%
Expected life (years)		4.3		4.2	—	6.5		4.3
Fair value of options (per share)		$5.13		$5.54	—	$6.06		$6.14

The Company does not anticipate paying any additional dividends in the foreseeable future. The estimated volatility is based on the historical volatility of our stock. The risk free rate for the periods within the expected life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The expected life of the options was calculated based on the historical exercise behavior.

13.   EARNINGS (LOSS) PER SHARE

Basic earnings (loss) per common share was computed by dividing net income (loss) by the weighted average number of shares outstanding during the period. Diluted earnings (loss) per common share was calculated as follows:

	For the Year Ended December 31,
	2013		2012		2011
	(in thousands, except per share data)
Net income (loss)	$	5,915	$	2,179	$	(2,857	)
Basic weighted average common shares outstanding		8,662		8,700		9,056
Dilutive effect of common stock equivalents		20		2		-
Diluted weighted average common shares outstanding		8,682		8,702		9,056
Basic earnings (loss) per share	$	0.68	$	0.25	$	(0.32	)
Diluted earnings (loss) per share	$	0.68	$	0.25	$	(0.32	)

Average options outstanding to purchase 14,915, 227,199 and 233,717 shares of common stock for December 31, 2013, 2012 and 2011, respectively, were not included in the computation of diluted earnings (loss) per share because to do so would have an anti-dilutive effect. 

14.   BENEFIT PLAN

The Company sponsors a benefit plan for the benefit of all eligible employees. The plan qualifies under Section 401(k) of the Internal Revenue Code thereby allowing eligible employees to make tax-deductible contributions to the plan. The plan provides for employer matching contributions of 50% of each participant’s voluntary contribution up to 3% of the participant’s compensation and vests at the rate of 20% each year until fully vested after five years. Total employer matching contributions to the plan were approximately $188,000, $193,000 and $224,000 in 2013, 2012 and 2011, respectively.

15.   COMMITMENTS AND CONTINGENCIES

The Company is not a party to any pending legal proceedings which management believes to be material to the Consolidated financial statements of the Company. The Company maintains liability insurance against risks arising out of the normal course of its business.

We are a defendant in a collective-action lawsuit which was filed on August 22, 2013, in the United States District Court for the Western District of Arkansas. The plaintiffs, who are current and former drivers and who worked for the Company during the period of August 22, 2010, through the date of the filing, allege claims for unpaid wages under the Fair Labor Standards Act and the Arkansas Minimum Wage Law. The complaint alleges that the Company failed to pay newly hired drivers minimum wage during orientation, training, and while traveling during normal business hours and that the Company failed to pay all drivers when working on assignment for more than 24 hours. The plaintiffs seek to enjoin the Company from continuing its current pay practices related to the allegations. They also seek actual damages, liquidated damages equal to accrual damages, court costs, and legal fees. The lawsuit is currently in the discovery stage. We cannot reasonably estimate at this time the possible loss or range of loss, if any, that may arise from this lawsuit. Management has determined that any losses under this claim would not be covered by exisiting insurance policies.

- 63 -

The Company leases certain premises under noncancelable operating lease agreements. Future minimum annual lease payments under these leases are as follows:

2014	$	369,483
2015		77,460
2016		-
2017		-
2018 and thereafter		-
Total	$	446,943

Total rental expense, net of amounts reimbursed for the years ended December 31, 2013, 2012 and 2011 was approximately $1,572,000, $1,555,000, and $1,602,000, respectively.

16.   FAIR VALUE OF FINANCIAL INSTRUMENTS

Our financial instruments consist of cash and cash equivalents, marketable equity securities, accounts receivable, trade accounts payable, and borrowings.

The Company adopted guidance effective January 1, 2008 for financial assets and liabilities measured on a recurring basis. This guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date and also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value:

Level 1:	Quoted market prices in active markets for identical assets or liabilities.
Level 2:	Inputs other than Level 1 inputs that are either directly or indirectly observable such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable; or other inputs not directly observable, but derived principally from, or corroborated by, observable market data.
Level 3:	Unobservable inputs that are supported by little or no market activity.

The Company utilizes the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.

At December 31, 2013, the following items are measured at fair value on a recurring basis:

	Total		Level 1		Level 2		Level 3
	(in thousands)
Marketable equity securities	$	20,975	$	20,975		-		-

The Company’s investments in marketable equity securities are recorded at fair value based on quoted market prices. The carrying value of cash and cash equivalents, accounts receivable, trade accounts payable, and accrued liabilities approximate fair value due to their short maturities.

The carrying amount for the line of credit approximates fair value because the line of credit interest rate is adjusted frequently.

- 64 -

For long-term debt other than the lines of credit, the fair values are estimated using discounted cash flow analyses, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. The carrying values and estimated fair values of this other long-term debt at December 31, 2013 and 2012 are summarized as follows:

	2013				2012
	Carrying Value		Estimated Fair Value		Carrying Value		Estimated Fair Value
	(in thousands)
Long-term debt	$	110,469	$	110,373	$	102,084	$	101,969

The Company has not elected the fair value option for any of our financial instruments.

17.   RELATED PARTY TRANSACTIONS

In the normal course of business, transactions for transportation and repair services, property leases and other services are conducted between the Company and companies affiliated with a major stockholder. The Company recognized approximately $10,350,000, $3,298,000 and $3,011,000 in operating revenue and approximately $1,303,000, $1,313,000 and $1,316,000 in operating expenses in 2013, 2012 and 2011, respectively. In addition, also in the normal course of business, the Company sold tractors to an affiliated company owned by a major stockholder for approximately $1,580,000.

The Company purchased physical damage, auto liability, and general liability insurance through an unaffiliated insurance broker which was written by an insurance company affiliated with a major stockholder. Premiums paid for physical damage coverage were approximately $2,036,000, $1,590,000 and $1,536,000 for 2013, 2012 and 2011, respectively. Premiums paid for auto liability coverage during 2013, 2012 and 2011 were approximately $9,461,000, $9,235,000 and $8,947,000, respectively. Premiums paid for general liability coverage during 2013, 2012 and 2011 were approximately $22,000 each year. Beginning in 2012, the Company secured coverage for workers’ compensation insurance under the same arrangement. Premiums paid for workers’ compensation coverage during 2013 and 2012 were approximately $254,000 and $84,000, respectively.

Amounts owed to the Company by these affiliates were approximately $3,852,000 and $1,822,000 at December 31, 2013 and 2012, respectively. Of the accounts receivable at December 31, 2013, approximately $11,000 represents revenue resulting from maintenance performed in the Company’s maintenance facilities and charges paid by the Company to third parties on behalf of their affiliate and charged back at the amount paid, approximately $3,809,000 represents freight transportation, and approximately $32,000 represents property lease charges.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.

None.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Based on management’s evaluation, our chief executive officer and chief financial officer concluded that, as of December 31, 2013, our disclosure controls and procedures are designed at a reasonable assurance level and are effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

We regularly review our system of internal control over financial reporting and make changes to our processes and systems to improve controls and increase efficiency, while ensuring that we maintain an effective internal control environment. Changes may include such activities as implementing new, more efficient systems, consolidating activities, and migrating processes.

There were no changes in our internal control over financial reporting that occurred during the last quarter of the period covered by this Annual Report on Form 10-K that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Exchange Act Rule 13a-15(f). Management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in the 1992 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2013. Management reviewed the results of its assessment with our Audit Committee. The effectiveness of our internal control over financial reporting as of December 31, 2013 has been audited by Grant Thornton LLP, an independent registered public accounting firm, as stated in its report which is included below.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

P.A.M. Transportation Services, Inc.

We have audited the internal control over financial reporting of P.A.M. Transportation Services, Inc. (a Delaware corporation) and subsidiaries (the “Company”) as of December 31, 2013, based on criteria established in the 1992 Internal Control—Integrated Framework 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. 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, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and 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, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on criteria established in the 1992 Internal Control—Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements of the Company as of and for the year ended December 31, 2013, and our report dated March 14, 2014 expressed an unqualified opinion on those financial statements.

Recent Sales of Unregistered Securities

On November 15, 2013, our Board of Directors approved the grant of a total of 9,500 restricted shares to certain key employees in recognition for their service to the Company. These shares, which were not awarded under any employee compensation plan of the Company, will vest in five equal annual installments beginning on November 15, 2014, provided that each recipient must be an employee of the Company at the time of vesting to receive the vested shares. We believe that these shares, when issued, will be exempt from registration under Section 4(a)(2) of the Securities Act of 1933.

Fair Value Disclosures [Abstract]

Fair Value Disclosures [Text Block]

16.   FAIR VALUE OF FINANCIAL INSTRUMENTS

Our financial instruments consist of cash and cash equivalents, marketable equity securities, accounts receivable, trade accounts payable, and borrowings.

The Company adopted guidance effective January 1, 2008 for financial assets and liabilities measured on a recurring basis. This guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date and also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value:

Level 1:	Quoted market prices in active markets for identical assets or liabilities.
Level 2:	Inputs other than Level 1 inputs that are either directly or indirectly observable such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable; or other inputs not directly observable, but derived principally from, or corroborated by, observable market data.
Level 3:	Unobservable inputs that are supported by little or no market activity.

The Company utilizes the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.

At December 31, 2013, the following items are measured at fair value on a recurring basis:

	Total		Level 1		Level 2		Level 3
	(in thousands)
Marketable equity securities	$	20,975	$	20,975		-		-

The Company’s investments in marketable equity securities are recorded at fair value based on quoted market prices. The carrying value of cash and cash equivalents, accounts receivable, trade accounts payable, and accrued liabilities approximate fair value due to their short maturities.

The carrying amount for the line of credit approximates fair value because the line of credit interest rate is adjusted frequently.

For long-term debt other than the lines of credit, the fair values are estimated using discounted cash flow analyses, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. The carrying values and estimated fair values of this other long-term debt at December 31, 2013 and 2012 are summarized as follows:

	2013				2012
	Carrying Value		Estimated Fair Value		Carrying Value		Estimated Fair Value
	(in thousands)
Long-term debt	$	110,469	$	110,373	$	102,084	$	101,969

The Company has not elected the fair value option for any of our financial instruments.

Accounting Policies [Abstract]

Consolidation, Policy [Policy Text Block]

Description of Business and Principles of Consolidation–P.A.M. Transportation Services, Inc. (the “Company”), through its subsidiaries, operates as a truckload transportation and logistics company.

The consolidated financial statements include the accounts of the Company and its wholly owned operating subsidiaries: P.A.M. Transport, Inc., P.A.M. Cartage Carriers, LLC, Overdrive Leasing, LLC, Choctaw Express, LLC, Decker Transport Co., LLC, T.T.X., LLC, Transcend Logistics, Inc., and East Coast Transport and Logistics, LLC. The following subsidiaries were inactive during all periods presented: P.A.M. International, Inc., P.A.M. Logistics Services, Inc., Choctaw Brokerage, Inc., P.A.M. Canada, Inc. and S & L Logistics, Inc.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates–The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of any contingent assets and liabilities at the financial statement date and reported amounts of revenue and expenses during the reporting period. The Company periodically reviews these estimates and assumptions. The Company's estimates were based on its historical experience and various other assumptions that the Company believes to be reasonable under the circumstances. Actual results could differ from those estimates

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents–The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.

Receivables, Policy [Policy Text Block]

Accounts Receivable and Allowance for Doubtful Accounts–Accounts receivable are presented in the Company’s consolidated financial statements net of an allowance for estimated uncollectible amounts. Management estimates this allowance based upon an evaluation of the aging of our customer receivables and historical write-offs, as well as other trends and factors surrounding the credit risk of specific customers. The Company continually updates the history it uses to make these estimates so as to reflect the most recent trends, factors and other information available. In order to gather information regarding these trends and factors, the Company also performs ongoing credit evaluations of its customers. Customer receivables are considered to be past due when payment has not been received by the invoice due date. Write-offs occur when we determine an account to be uncollectible and could differ from the allowance estimate as a result of a number of factors, including unanticipated changes in the overall economic environment or factors and risks surrounding a particular customer. Management believes its methodology for estimating the allowance for doubtful accounts to be reliable however, additional allowances may be required if the financial condition of our customers were to deteriorate, and could have a material effect on the Company’s consolidated financial statements.

Bank Overdrafts [Policy Text Block]

Bank Overdrafts–The Company classifies bank overdrafts in current liabilities as an accounts payable and does not offset other positive bank account balances located at the same or other financial institutions. Bank overdrafts generally represent checks written that have not yet cleared the Company’s bank accounts. The majority of the Company’s bank accounts are zero balance accounts that are funded at the time items clear against the account by drawings against a line of credit, therefore the outstanding checks represent bank overdrafts. Because the recipients of these checks have generally not yet received payment, the Company continues to classify bank overdrafts as accounts payable. Bank overdrafts are classified as changes in accounts payable in the cash flows from operating activities section of the Company’s Consolidated Statement of Cash Flows. Bank overdrafts as of December 31, 2013 and 2012 were approximately $3,179,000 and $4,803,000, respectively.

Trade and Other Accounts Receivable, Policy [Policy Text Block]

Accounts Receivable Other–The components of accounts receivable other consist primarily of amounts representing company driver advances, owner-operator advances, equipment manufacturer warranties, and restricted cash. Advances receivable from company drivers as of December 31, 2013 and 2012, were approximately $707,000 and $882,000, respectively. Restricted cash consists of cash proceeds from the sale of trucks and trailers under our like-kind exchange (“LKE”) tax program. See Note 11, “Federal and State Income Taxes,” for a discussion of the Company’s LKE tax program. We classify restricted cash as a current asset within “Accounts receivable-other” as the exchange process must be completed within 180 days in order to qualify for income tax deferral treatment. The changes in restricted cash balances are reflected as an investing activity in our Consolidated Statements of Cash Flows as they relate to the sales and purchases of revenue equipment.

Marketable Securities, Policy [Policy Text Block]

Marketable Equity Securities–Marketable equity securities are classified by the Company as either available for sale or trading. Securities classified as available for sale are carried at market value with unrealized gains and losses recognized in accumulated other comprehensive income in the statements of stockholders’ equity. Securities classified as trading are carried at market value with unrealized gains and losses recognized in the statements of operations. Realized gains and losses are computed utilizing the specific identification method.

Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]

Impairment of Long-Lived Assets–The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset may not be recoverable. An impairment loss would be recognized if the carrying amount of the long-lived asset is not recoverable, and it exceeds its fair value. For long-lived assets classified as held and used, if the carrying value of the long-lived asset exceeds the sum of the future net cash flows, it is not recoverable.

Property, Plant and Equipment, Policy [Policy Text Block]

Property and Equipment–Property and equipment is recorded at historical cost, less accumulated depreciation. For financial reporting purposes, the cost of such property is depreciated principally by the straight-line method. For tax reporting purposes, accelerated depreciation or applicable cost recovery methods are used. Depreciation is recognized over the estimated asset life, considering the estimated salvage value of the asset. Such salvage values are based on estimates using expected market values for used equipment and the estimated time of disposal which, in many cases include guaranteed residual values by the manufacturers. Gains and losses are reflected in the year of disposal. The following is a table reflecting estimated ranges of asset useful lives by major class of depreciable assets:

Asset Class	Estimated Asset Life
Service vehicles (years)	3	-	5
Office furniture and equipment (years)	3	-	7
Revenue equipment (years)	3	-	12
Structure and improvements (years)	5	-	40

The Company’s management periodically evaluates whether changes to estimated useful lives and/or salvage values are necessary to ensure its estimates accurately reflect the economic use of the assets. During 2013, management adjusted the estimated useful lives and salvage values of certain trucks based on such an evaluation. These changes resulted in a decrease in depreciation expense of approximately $550,000 during 2013. This reduction in depreciation expense increased the Company’s 2013 reported net income by approximately $340,000 ($0.04 per diluted share).

During 2012, management adjusted the estimated useful lives and salvage values of certain trucks based on such an evaluation. These changes resulted in a decrease in depreciation expense of approximately $450,000 during 2012. This reduction in depreciation expense increased the Company’s 2012 reported net income by approximately $300,000 ($0.03 per diluted share).

During 2011, management decreased the estimated useful lives and adjusted the salvage values of certain trucks which were expected to be traded for newer model trucks. These changes resulted in additional depreciation expense of approximately $4,200,000 during 2011. This additional depreciation expense increased the Company’s 2011 reported net loss by approximately $2,600,000 ($0.29 per diluted share).

Prepaid Tires [Policy Text Block]

Prepaid Tires–Tires purchased with revenue equipment are capitalized as a cost of the related equipment. Replacement tires are included in prepaid expenses and deposits and are amortized over a 24-month period. Amounts paid for the recapping of tires are expensed when incurred.

Advertising Costs, Policy [Policy Text Block]

Advertising Expense–Advertising costs are expensed as incurred and totaled approximately $662,000, $685,000 and $437,000 for the years ended December 31, 2013, 2012 and 2011, respectively.

Reclassification, Policy [Policy Text Block]

Classification of Owner/Operator Expense – In order to conform to industry practice, the Company began to classify payments to third-party owner operator drivers as purchased transportation rather than as salaries, wages and benefits as had been presented in reports prior to the period ended September 30, 2013. This reclassification has no effect on operating income, net income or earnings per share. The Company has made corresponding reclassifications to comparative periods shown.

Maintenance Cost, Policy [Policy Text Block]

Repairs and Maintenance–Repairs and maintenance costs are expensed as incurred.

Self Insurance Liability [Policy Text Block]

Self Insurance Liability–A liability is recognized for known health, workers’ compensation, cargo damage, property damage and auto liability damage claims. An estimate of the incurred but not reported claims for each type of liability is made based on historical claims made, estimated frequency of occurrence, and considering changing factors that contribute to the overall cost of insurance.

Income Tax, Policy [Policy Text Block]

Income Taxes–The Company applies the asset and liability method of accounting for income taxes, under which deferred taxes are determined based on the temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the basis differences reverse. A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized.

The application of income tax law to multi-jurisdictional operations such as those performed by the Company, are inherently complex. Laws and regulations in this area are voluminous and often ambiguous. As such, we may be required to make subjective assumptions and judgments regarding our income tax exposures. Interpretations of and guidance surrounding income tax laws and regulations may change over time which could cause changes in our assumptions and judgments that could materially affect amounts recognized in the consolidated financial statements.

We recognize the impact of tax positions in our financial statements. These tax positions must meet a more-likely-than-not recognition threshold to be recognized and tax positions that previously failed to meet the more-likely-than-not threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not threshold are derecognized in the first subsequent financial reporting period in which that threshold is no longer met. We recognize potential accrued interest and penalties related to unrecognized tax benefits within the consolidated statements of income as income tax expense.

In determining whether a tax asset valuation allowance is necessary, management, in accordance with the provisions of ASC 740-10-30, weighs all available evidence, both positive and negative to determine whether, based on the weight of that evidence, a valuation allowance is necessary. If negative conditions exist which indicate a valuation allowance might be necessary, consideration is then given to what effect the future reversals of existing taxable temporary differences and the availability of tax strategies might have on future taxable income to determine the amount, if any, of the required valuation allowance. As of December 31, 2013, management determined that the future reversals of existing taxable temporary differences and available tax strategies would generate sufficient future taxable income to realize its tax assets and therefore a valuation allowance was not necessary.

Revenue Recognition, Policy [Policy Text Block]

Revenue Recognition–Revenue is recognized in full upon completion of delivery to the receiver’s location. For freight in transit at the end of a reporting period, the Company recognizes revenue pro rata based on relative transit time completed as a portion of the estimated total transit time. Expenses are recognized as incurred.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]

Share-Based Compensation–The Company estimates the fair value of stock option awards on the option grant date using the Black-Scholes pricing model and recognizes compensation for stock option awards expected to vest on a straight-line basis over the requisite service period for the entire award. Forfeitures are estimated at grant date based on historical experience. For additional information with respect to share-based compensation, see Note 12 to our consolidated financial statements.

Earnings Per Share, Policy [Policy Text Block]

Earnings Per Share–The Company computes basic earnings per share (“EPS”) by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS includes the potential dilution that could occur from stock-based awards and other stock-based commitments using the treasury stock or the as if converted methods, as applicable. The difference between the Company's weighted-average shares outstanding and diluted shares outstanding is due to the dilutive effect of stock options for all periods presented. See Note 13 for computation of diluted EPS.

Fair Value Measurement, Policy [Policy Text Block]

Fair Value Measurements–Certain financial assets and liabilities are measured at fair value within the financial statements on a recurring basis. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. For additional information with respect to fair value measurements, see Note 16 to our consolidated financial statements.

Segment Reporting, Policy [Policy Text Block]

Reporting Segments–The Company's operations are all in the motor carrier segment and are aggregated into a single reporting segment in accordance with the aggregation criteria under Generally Accepted Accounting Principles (“GAAP”). The Company provides truckload transportation services as well as brokerage and logistics services to customers throughout the United States and portions of Canada and Mexico. Truckload transportation services revenues, excluding fuel surcharges, represented 92.6%, 91.8% and 93.5% of total revenues, excluding fuel surcharges, for the twelve months ended December 31, 2013, 2012 and 2011, respectively. Remaining revenues, excluding fuel surcharges, for each respective year were generated by brokerage and logistics services.

Concentration Risk, Credit Risk, Policy [Policy Text Block]

Concentrations of Credit Risk–The Company performs ongoing credit evaluations and generally does not require collateral from its customers. The Company maintains reserves for potential credit losses. In view of the concentration of the Company’s revenues and accounts receivable among a limited number of customers within the automobile industry, the financial health of this industry is a factor in the Company’s overall evaluation of accounts receivable.

Subsequent Events, Policy [Policy Text Block]

Subsequent Events–We have evaluated subsequent events for recognition and disclosure through the date these financial statements were filed with the United States Securities and Exchange Commission and concluded that no subsequent events or transactions have occurred that require recognition or disclosure in our financial statements.

Foreign Currency Transactions and Translations Policy [Policy Text Block]

Foreign Currency Transactions– The functional currency of the Company’s foreign branch office in Mexico is the U.S. dollar. The Company remeasures the monetary assets and liabilities of this branch office, which are maintained in the local currency ledgers, at the rates of exchange in effect at the end of the reporting period. Revenues and expenses recorded in the local currency during the period are remeasured using average exchange rates for each period. Non-monetary assets and liabilities are remeasured using historical rates. Any resulting exchange gain or loss from the remeasurement process are included in non-operating income in the Company’s consolidated statements of operations.

New Accounting Pronouncements, Policy [Policy Text Block]

Recent Accounting Pronouncements– In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) No. 2013-2, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. This guidance requires an organization to present the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income (“OCI”), but only if the item reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. The guidance is effective for fiscal years beginning after December 15, 2012. The adoption of this guidance on January 1, 2013 did not have a significant impact on the Company’s financial condition, results of operations, or cash flow.

In December 2011, the FASB issued ASU No. 2011-11, Disclosures about Offsetting Assets and Liabilities, which requires entities to disclose both gross and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting agreement. The objective of the disclosure is to facilitate comparison between those entities that prepare their financial statements on the basis of U.S. GAAP and those entities that prepare their financial statements on the basis of International Financial Reporting Standards. Retrospective presentation for all comparative periods presented is required. This ASU is effective for fiscal years, and interim periods within those years, beginning on or after January 1, 2013. The adoption of this guidance on January 1, 2013 did not have a material effect on the Company’s financial condition, results of operations, or cash flow.

Earnings Per Share [Text Block]

13.   EARNINGS (LOSS) PER SHARE

Basic earnings (loss) per common share was computed by dividing net income (loss) by the weighted average number of shares outstanding during the period. Diluted earnings (loss) per common share was calculated as follows:

	For the Year Ended December 31,
	2013		2012		2011
	(in thousands, except per share data)
Net income (loss)	$	5,915	$	2,179	$	(2,857	)

Diluted earnings (loss) per share	$	0.68	$	0.25	$	(0.32	)

Average options outstanding to purchase 14,915, 227,199 and 233,717 shares of common stock for December 31, 2013, 2012 and 2011, respectively, were not included in the computation of diluted earnings (loss) per share because to do so would have an anti-dilutive effect.

15.   COMMITMENTS AND CONTINGENCIES

The Company is not a party to any pending legal proceedings which management believes to be material to the Consolidated financial statements of the Company. The Company maintains liability insurance against risks arising out of the normal course of its business.

We are a defendant in a collective-action lawsuit which was filed on August 22, 2013, in the United States District Court for the Western District of Arkansas. The plaintiffs, who are current and former drivers and who worked for the Company during the period of August 22, 2010, through the date of the filing, allege claims for unpaid wages under the Fair Labor Standards Act and the Arkansas Minimum Wage Law. The complaint alleges that the Company failed to pay newly hired drivers minimum wage during orientation, training, and while traveling during normal business hours and that the Company failed to pay all drivers when working on assignment for more than 24 hours. The plaintiffs seek to enjoin the Company from continuing its current pay practices related to the allegations. They also seek actual damages, liquidated damages equal to accrual damages, court costs, and legal fees. The lawsuit is currently in the discovery stage. We cannot reasonably estimate at this time the possible loss or range of loss, if any, that may arise from this lawsuit. Management has determined that any losses under this claim would not be covered by exisiting insurance policies.

The Company leases certain premises under noncancelable operating lease agreements. Future minimum annual lease payments under these leases are as follows:

2014	$	369,483
2015		77,460
2016		-
2017		-
2018 and thereafter		-
Total	$	446,943

Total rental expense, net of amounts reimbursed for the years ended December 31, 2013, 2012 and 2011 was approximately $1,572,000, $1,555,000, and $1,602,000, respectively.

Investments in Debt and Marketable Equity Securities (and Certain Trading Assets) Disclosure [Text Block]

3.     MARKETABLE EQUITY SECURITIES

The Company accounts for its marketable securities in accordance with ASC Topic 320, Investments-Debt and Equity Securities. ASC Topic 320 requires companies to classify their investments as trading, available-for-sale or held-to-maturity. The Company’s investments in marketable securities are classified as either trading or available-for-sale and consist of equity securities. Management determines the appropriate classification of these securities at the time of purchase and re-evaluates such designation as of each balance sheet date. The cost of securities sold is based on the specific identification method and interest and dividends on securities are included in non-operating income.

Marketable equity securities classified as available-for-sale are carried at fair value, with the unrealized gains and losses, net of tax, included as a component of accumulated other comprehensive income in stockholders’ equity. Realized gains and losses, declines in value judged to be other-than-temporary on available-for-sale securities, and increases or decreases in value on trading securities, if any, are included in the determination of net income. A quarterly evaluation is performed in order to judge whether declines in value below cost should be considered temporary and when losses are deemed to be other-than-temporary. Several factors are considered in this evaluation process including the severity and duration of the decline in value, the financial condition and near-term outlook for the specific issuer and the Company’s ability to hold the securities.

For the years ended December 31, 2013, 2012 and 2011, the evaluation resulted in an impairment charges of approximately $29,000, $70,000 and $315,000, respectively, being reported in the Company’s non-operating income in its statement of operations.

The following table sets forth cost, market value and unrealized gain/(loss) on equity securities classified as available-for-sale and equity securities classified as trading as of December 31, 2013 and 2012.

The Company's authorized capital stock consists of 40,000,000 shares of common stock, par value $.01 per share, and 10,000,000 shares of preferred stock, par value $.01 per share. At December 31, 2013, there were 11,391,464 shares of our common stock issued and 7,983,539 shares outstanding. No shares of our preferred stock were issued or outstanding at December 31, 2013.

Common Stock

The holders of our common stock, subject to such rights as may be granted to any preferred stockholders, elect all directors and are entitled to one vote per share. All shares of common stock participate equally in dividends when and as declared by the Board of Directors and in net assets on liquidation. The shares of common stock have no preference, conversion, exchange, preemptive or cumulative voting rights.

Preferred Stock

Preferred stock may be issued from time to time by our Board of Directors, without stockholder approval, in such series and with such preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends, qualifications or other provisions, as may be fixed by the Board of Directors in the resolution authorizing their issuance. The issuance of preferred stock by the Board of Directors could adversely affect the rights of holders of shares of common stock; for example, the issuance of preferred stock could result in a class of securities outstanding that would have certain preferences with respect to dividends and in liquidation over the common stock, and that could result in a dilution of the voting rights, net income per share and net book value of the common stock. As of December 31, 2013, we have no agreements or understandings for the issuance of any shares of preferred stock.

Treasury Stock

In November 2010, our Board of Directors authorized the repurchase of up to 500,000 shares of our common stock during the twelve month period following the announcement. All 500,000 shares were repurchased under this repurchase authorization prior to the authorization expiration date.

In September 2011, our Board of Directors authorized the repurchase of up to 500,000 shares of our common stock. Under this authorization, the Company repurchased 224,000 shares of its common stock during the fourth quarter of 2011. The Company did not repurchase any additional shares during 2012. The Company repurchased a total of 50,325 shares of its common stock under this authorization during 2013.

In November 2013, our Board of Directors authorized the repurchase of up to 600,000 shares of our common stock through a Dutch auction tender offer (the “tender offer”). Subject to certain limitations and legal requirements, the Company could repurchase up to an additional 2% of its outstanding shares which totaled 173,000 shares. The tender offer began on the date of the announcement, December 2, 2013 and expired on December 30, 2013. Through the tender offer, the Company’s shareholders had the opportunity to tender some or all of their shares at a price within the range of $19.00 to 21.00 per share. Upon expiration, 675,000 shares were tendered through the offer at a final purchase price of $20.50 per share for a total purchase price of approximately $13.9 million, including fees and commission and was settled on January 6, 2014.

Compensation and Employee Benefit Plans [Text Block]

12.   STOCK-BASED COMPENSATION

The Company maintains a stock option plan under which incentive stock options and nonqualified stock options may be granted. On March 2, 2006, the Company’s Board of Director’s adopted, and stockholders later approved, the 2006 Stock Option Plan (the “2006 Plan”). The 2006 Plan replaced the expired 1995 Stock Option Plan which had 263,500 options remaining which were never issued. Under the 2006 Plan 750,000 shares were reserved for the issuance of stock options to directors, officers, key employees and others. The option exercise price under the 2006 Plan is the fair market value of the stock on the date the option is granted. The fair market value is determined by the average of the highest and lowest sales prices for a share of the Company’s common stock, on its primary exchange, on the same date that the option is granted.

Outstanding nonqualified stock options at December 31, 2013, must be exercised within either five or ten years from the date of grant. Nonqualified stock options granted to members of the Company’s Board of Directors vest immediately while nonqualified stock options issued to employees vest in increments of 20% each year. During 2013, nonqualified options for 35,000 shares were issued to members of the Company’s Board of Directors under the 2006 Plan at an option exercise price of $10.44 per share. At December 31, 2013, 366,000 shares were available for granting future options.

Also, during 2013 the Compensation Committee of the Board of Directors granted 9,500 restricted shares of the Company’s stock to certain key employees. This restricted stock award has a grant date fair value of $18.17, based on the closing price of the Company’s stock on the date of grant, and vests in increments of 20% each year.

In May 2012, the Company granted to certain key employees, 104,000 nonqualified stock options. The exercise price for these awards was fixed at the grant date and was equal to the fair market value of the stock on that date. These nonqualified stock options vest in increments of 20% each year.

In November 2010, the Company granted to certain key employees, 50,000 nonqualified stock options and 64,000 performance-based variable nonqualified stock options. The exercise price for these awards was fixed at the grant date and was equal to the fair market value of the stock on that date. The nonqualified stock options vest in increments of 20% each year. The performance-based nonqualified stock options were eligible to be earned in four quarterly installments and one annual installment with vesting to occur in increments of 20% each year for any options earned. In order to meet the performance criteria, certain quarterly and annual “operating ratio” results must have been achieved during 2011. During 2011, 4,442 performance-based variable nonqualified stock options were earned with vesting to begin during the third quarter of 2012. The remaining 59,558 performance-based variable nonqualified stock options expired as the related performance criteria was not met.

The grant date fair value of options vested during 2013, 2012 and 2011 was approximately $346,000, $268,000 and $162,000, respectively. No restricted shares vested during any of the years presented. Total pre-tax stock-based compensation expense, recognized in Salaries, wages and benefits was approximately $317,000 during 2013 and includes approximately $179,000 as a result of the increased annual grant of 5,000 shares to each non-employee director during 2013. The Company recognized a total income tax benefit of approximately $123,000 related to stock-based compensation expense during 2013. The recognition of stock-based compensation expense decreased diluted earnings per common share and basic earnings per common share by approximately $0.02 and $0.03, respectively during 2013. As of December 31, 2013, the Company had stock-based compensation plans with total unvested stock-based compensation expense of approximately $518,000 which is being amortized on a straight-line basis over the remaining vesting period. As a result, the Company expects to recognize approximately $156,000 in additional compensation expense related to unvested option awards during 2014, $151,000 in additional compensation expense related to unvested option awards during 2015, $120,000 in additional compensation expense related to unvested option awards during 2016, $62,000 in additional compensation expense related to unvested option awards during 2017 and $29,000 in additional compensation expense related to unvested option awards during 2018.

Total pre-tax stock-based compensation expense, recognized in Salaries, wages and benefits was approximately $352,000 during 2012 and included approximately $199,000 recognized as a result of the annual grant of 5,000 shares to each non-employee director during the first quarter of 2012. The Company recognized a total income tax benefit of approximately $139,000 related to stock-based compensation expense during 2012. The recognition of stock-based compensation expense decreased diluted and basic income per common share by approximately $0.02 during 2012. At December 31, 2012, the Company had stock-based compensation plans with total unvested stock-based compensation expense of approximately $749,000.

Total pre-tax stock-based compensation expense, recognized in Salaries, wages and benefits was approximately $164,000 during 2011 and included approximately $98,000 recognized as a result of the annual grant of 2,000 shares to each non-employee director during the first quarter of 2011. The Company recognized a total income tax benefit of approximately $80,000 related to stock-based compensation expense during 2011. The recognition of stock-based compensation expense increased diluted and basic loss per common share by approximately $0.01 during 2011. At December 31, 2011, the Company had stock-based compensation plans with total unvested stock-based compensation expense of approximately $272,000.

Transactions in stock options under these plans are summarized as follows:

Options exercisable—December 31, 2013:		96,059		$	11.01

The fair value of the Company’s stock options was estimated at the date of grant using a Black-Scholes-Merton (“BSM”) option-pricing model using the following assumptions:

	2013		2012				2011
Dividend yield		0%			0%			0%
Volatility range		62.69%		57.88%	—	65.89%		65.81%
Risk-free rate range		0.61%		0.64%	—	1.09%		1.79%
Expected life (years)		4.3		4.2	—	6.5		4.3
Fair value of options (per share)		$5.13		$5.54	—	$6.06		$6.14

The Company does not anticipate paying any additional dividends in the foreseeable future. The estimated volatility is based on the historical volatility of our stock. The risk free rate for the periods within the expected life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The expected life of the options was calculated based on the historical exercise behavior.

Accounting Policies [Abstract]

Significant Accounting Policies [Text Block]

1.     ACCOUNTING POLICIES

Description of Business and Principles of Consolidation–P.A.M. Transportation Services, Inc. (the “Company”), through its subsidiaries, operates as a truckload transportation and logistics company.

The consolidated financial statements include the accounts of the Company and its wholly owned operating subsidiaries: P.A.M. Transport, Inc., P.A.M. Cartage Carriers, LLC, Overdrive Leasing, LLC, Choctaw Express, LLC, Decker Transport Co., LLC, T.T.X., LLC, Transcend Logistics, Inc., and East Coast Transport and Logistics, LLC. The following subsidiaries were inactive during all periods presented: P.A.M. International, Inc., P.A.M. Logistics Services, Inc., Choctaw Brokerage, Inc., P.A.M. Canada, Inc. and S & L Logistics, Inc.

Use of Estimates–The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of any contingent assets and liabilities at the financial statement date and reported amounts of revenue and expenses during the reporting period. The Company periodically reviews these estimates and assumptions. The Company's estimates were based on its historical experience and various other assumptions that the Company believes to be reasonable under the circumstances. Actual results could differ from those estimates.

Cash and Cash Equivalents–The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.

Accounts Receivable and Allowance for Doubtful Accounts–Accounts receivable are presented in the Company’s consolidated financial statements net of an allowance for estimated uncollectible amounts. Management estimates this allowance based upon an evaluation of the aging of our customer receivables and historical write-offs, as well as other trends and factors surrounding the credit risk of specific customers. The Company continually updates the history it uses to make these estimates so as to reflect the most recent trends, factors and other information available. In order to gather information regarding these trends and factors, the Company also performs ongoing credit evaluations of its customers. Customer receivables are considered to be past due when payment has not been received by the invoice due date. Write-offs occur when we determine an account to be uncollectible and could differ from the allowance estimate as a result of a number of factors, including unanticipated changes in the overall economic environment or factors and risks surrounding a particular customer. Management believes its methodology for estimating the allowance for doubtful accounts to be reliable however, additional allowances may be required if the financial condition of our customers were to deteriorate, and could have a material effect on the Company’s consolidated financial statements.

Bank Overdrafts–The Company classifies bank overdrafts in current liabilities as an accounts payable and does not offset other positive bank account balances located at the same or other financial institutions. Bank overdrafts generally represent checks written that have not yet cleared the Company’s bank accounts. The majority of the Company’s bank accounts are zero balance accounts that are funded at the time items clear against the account by drawings against a line of credit, therefore the outstanding checks represent bank overdrafts. Because the recipients of these checks have generally not yet received payment, the Company continues to classify bank overdrafts as accounts payable. Bank overdrafts are classified as changes in accounts payable in the cash flows from operating activities section of the Company’s Consolidated Statement of Cash Flows. Bank overdrafts as of December 31, 2013 and 2012 were approximately $3,179,000 and $4,803,000, respectively.

Accounts Receivable Other–The components of accounts receivable other consist primarily of amounts representing company driver advances, owner-operator advances, equipment manufacturer warranties, and restricted cash. Advances receivable from company drivers as of December 31, 2013 and 2012, were approximately $707,000 and $882,000, respectively. Restricted cash consists of cash proceeds from the sale of trucks and trailers under our like-kind exchange (“LKE”) tax program. See Note 11, “Federal and State Income Taxes,” for a discussion of the Company’s LKE tax program. We classify restricted cash as a current asset within “Accounts receivable-other” as the exchange process must be completed within 180 days in order to qualify for income tax deferral treatment. The changes in restricted cash balances are reflected as an investing activity in our Consolidated Statements of Cash Flows as they relate to the sales and purchases of revenue equipment.

Marketable Equity Securities–Marketable equity securities are classified by the Company as either available for sale or trading. Securities classified as available for sale are carried at market value with unrealized gains and losses recognized in accumulated other comprehensive income in the statements of stockholders’ equity. Securities classified as trading are carried at market value with unrealized gains and losses recognized in the statements of operations. Realized gains and losses are computed utilizing the specific identification method.

Impairment of Long-Lived Assets–The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset may not be recoverable. An impairment loss would be recognized if the carrying amount of the long-lived asset is not recoverable, and it exceeds its fair value. For long-lived assets classified as held and used, if the carrying value of the long-lived asset exceeds the sum of the future net cash flows, it is not recoverable.

Property and Equipment–Property and equipment is recorded at historical cost, less accumulated depreciation. For financial reporting purposes, the cost of such property is depreciated principally by the straight-line method. For tax reporting purposes, accelerated depreciation or applicable cost recovery methods are used. Depreciation is recognized over the estimated asset life, considering the estimated salvage value of the asset. Such salvage values are based on estimates using expected market values for used equipment and the estimated time of disposal which, in many cases include guaranteed residual values by the manufacturers. Gains and losses are reflected in the year of disposal. The following is a table reflecting estimated ranges of asset useful lives by major class of depreciable assets:

Asset Class	Estimated Asset Life
Service vehicles (years)	3	-	5
Office furniture and equipment (years)	3	-	7
Revenue equipment (years)	3	-	12
Structure and improvements (years)	5	-	40

The Company’s management periodically evaluates whether changes to estimated useful lives and/or salvage values are necessary to ensure its estimates accurately reflect the economic use of the assets. During 2013, management adjusted the estimated useful lives and salvage values of certain trucks based on such an evaluation. These changes resulted in a decrease in depreciation expense of approximately $550,000 during 2013. This reduction in depreciation expense increased the Company’s 2013 reported net income by approximately $340,000 ($0.04 per diluted share).

During 2012, management adjusted the estimated useful lives and salvage values of certain trucks based on such an evaluation. These changes resulted in a decrease in depreciation expense of approximately $450,000 during 2012. This reduction in depreciation expense increased the Company’s 2012 reported net income by approximately $300,000 ($0.03 per diluted share).

During 2011, management decreased the estimated useful lives and adjusted the salvage values of certain trucks which were expected to be traded for newer model trucks. These changes resulted in additional depreciation expense of approximately $4,200,000 during 2011. This additional depreciation expense increased the Company’s 2011 reported net loss by approximately $2,600,000 ($0.29 per diluted share).

Prepaid Tires–Tires purchased with revenue equipment are capitalized as a cost of the related equipment. Replacement tires are included in prepaid expenses and deposits and are amortized over a 24-month period. Amounts paid for the recapping of tires are expensed when incurred.

Advertising Expense–Advertising costs are expensed as incurred and totaled approximately $662,000, $685,000 and $437,000 for the years ended December 31, 2013, 2012 and 2011, respectively.

Classification of Owner/Operator Expense – In order to conform to industry practice, the Company began to classify payments to third-party owner operator drivers as purchased transportation rather than as salaries, wages and benefits as had been presented in reports prior to the period ended September 30, 2013. This reclassification has no effect on operating income, net income or earnings per share. The Company has made corresponding reclassifications to comparative periods shown.

Repairs and Maintenance–Repairs and maintenance costs are expensed as incurred.

Self Insurance Liability–A liability is recognized for known health, workers’ compensation, cargo damage, property damage and auto liability damage claims. An estimate of the incurred but not reported claims for each type of liability is made based on historical claims made, estimated frequency of occurrence, and considering changing factors that contribute to the overall cost of insurance.

Income Taxes–The Company applies the asset and liability method of accounting for income taxes, under which deferred taxes are determined based on the temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the basis differences reverse. A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized.

The application of income tax law to multi-jurisdictional operations such as those performed by the Company, are inherently complex. Laws and regulations in this area are voluminous and often ambiguous. As such, we may be required to make subjective assumptions and judgments regarding our income tax exposures. Interpretations of and guidance surrounding income tax laws and regulations may change over time which could cause changes in our assumptions and judgments that could materially affect amounts recognized in the consolidated financial statements.

We recognize the impact of tax positions in our financial statements. These tax positions must meet a more-likely-than-not recognition threshold to be recognized and tax positions that previously failed to meet the more-likely-than-not threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not threshold are derecognized in the first subsequent financial reporting period in which that threshold is no longer met. We recognize potential accrued interest and penalties related to unrecognized tax benefits within the consolidated statements of income as income tax expense.

In determining whether a tax asset valuation allowance is necessary, management, in accordance with the provisions of ASC 740-10-30, weighs all available evidence, both positive and negative to determine whether, based on the weight of that evidence, a valuation allowance is necessary. If negative conditions exist which indicate a valuation allowance might be necessary, consideration is then given to what effect the future reversals of existing taxable temporary differences and the availability of tax strategies might have on future taxable income to determine the amount, if any, of the required valuation allowance. As of December 31, 2013, management determined that the future reversals of existing taxable temporary differences and available tax strategies would generate sufficient future taxable income to realize its tax assets and therefore a valuation allowance was not necessary.

Revenue Recognition–Revenue is recognized in full upon completion of delivery to the receiver’s location. For freight in transit at the end of a reporting period, the Company recognizes revenue pro rata based on relative transit time completed as a portion of the estimated total transit time. Expenses are recognized as incurred.

Share-Based Compensation–The Company estimates the fair value of stock option awards on the option grant date using the Black-Scholes pricing model and recognizes compensation for stock option awards expected to vest on a straight-line basis over the requisite service period for the entire award. Forfeitures are estimated at grant date based on historical experience. For additional information with respect to share-based compensation, see Note 12 to our consolidated financial statements.

Earnings Per Share–The Company computes basic earnings per share (“EPS”) by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS includes the potential dilution that could occur from stock-based awards and other stock-based commitments using the treasury stock or the as if converted methods, as applicable. The difference between the Company's weighted-average shares outstanding and diluted shares outstanding is due to the dilutive effect of stock options for all periods presented. See Note 13 for computation of diluted EPS.

Fair Value Measurements–Certain financial assets and liabilities are measured at fair value within the financial statements on a recurring basis. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. For additional information with respect to fair value measurements, see Note 16 to our consolidated financial statements.

Reporting Segments–The Company's operations are all in the motor carrier segment and are aggregated into a single reporting segment in accordance with the aggregation criteria under Generally Accepted Accounting Principles (“GAAP”). The Company provides truckload transportation services as well as brokerage and logistics services to customers throughout the United States and portions of Canada and Mexico. Truckload transportation services revenues, excluding fuel surcharges, represented 92.6%, 91.8% and 93.5% of total revenues, excluding fuel surcharges, for the twelve months ended December 31, 2013, 2012 and 2011, respectively. Remaining revenues, excluding fuel surcharges, for each respective year were generated by brokerage and logistics services.

Concentrations of Credit Risk–The Company performs ongoing credit evaluations and generally does not require collateral from its customers. The Company maintains reserves for potential credit losses. In view of the concentration of the Company’s revenues and accounts receivable among a limited number of customers within the automobile industry, the financial health of this industry is a factor in the Company’s overall evaluation of accounts receivable.

Subsequent Events–We have evaluated subsequent events for recognition and disclosure through the date these financial statements were filed with the United States Securities and Exchange Commission and concluded that no subsequent events or transactions have occurred that require recognition or disclosure in our financial statements.

Foreign Currency Transactions– The functional currency of the Company’s foreign branch office in Mexico is the U.S. dollar. The Company remeasures the monetary assets and liabilities of this branch office, which are maintained in the local currency ledgers, at the rates of exchange in effect at the end of the reporting period. Revenues and expenses recorded in the local currency during the period are remeasured using average exchange rates for each period. Non-monetary assets and liabilities are remeasured using historical rates. Any resulting exchange gain or loss from the remeasurement process are included in non-operating income in the Company’s consolidated statements of operations.

Recent Accounting Pronouncements– In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) No. 2013-2, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. This guidance requires an organization to present the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income (“OCI”), but only if the item reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. The guidance is effective for fiscal years beginning after December 15, 2012. The adoption of this guidance on January 1, 2013 did not have a significant impact on the Company’s financial condition, results of operations, or cash flow.

In December 2011, the FASB issued ASU No. 2011-11, Disclosures about Offsetting Assets and Liabilities, which requires entities to disclose both gross and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting agreement. The objective of the disclosure is to facilitate comparison between those entities that prepare their financial statements on the basis of U.S. GAAP and those entities that prepare their financial statements on the basis of International Financial Reporting Standards. Retrospective presentation for all comparative periods presented is required. This ASU is effective for fiscal years, and interim periods within those years, beginning on or after January 1, 2013. The adoption of this guidance on January 1, 2013 did not have a material effect on the Company’s financial condition, results of operations, or cash flow.

		3,597		1,365		(2,768	)
Total income tax expense (benefit)	$	3,756	$	1,416	$	(2,733	)

The Company has alternative minimum tax credits of approximately $318,000 at December 31, 2013, which have no expiration date under the current federal income tax laws and general business credits of approximately $988,000 which begin to expire after the year 2030. The Company also has net operating loss carryovers for federal income purposes of approximately $55,994,000 which begin to expire after the year 2030.

In determining whether a tax asset valuation allowance is necessary, management, in accordance with the provisions of ASC 740-10-30, weighs all available evidence, both positive and negative to determine whether, based on the weight of that evidence, a valuation allowance is necessary. If negative conditions exist which indicate a valuation allowance might be necessary, consideration is then given to what effect the future reversals of existing taxable temporary differences and the availability of tax strategies might have on future taxable income to determine the amount, if any, of the required valuation allowance. As of December 31, 2013, management determined that the future reversals of existing taxable temporary differences and available tax strategies would generate sufficient future taxable income to realize its tax assets and therefore a valuation allowance was not necessary.

The Company does not have any material accrued interest or penalties associated with any unrecognized tax benefits. The Company's policy is to account for interest and penalties related to uncertain tax positions, if any, in income tax expense. The Company did not have any unrecognized tax benefits at December 31, 2013 or December 31, 2012 and there was no change in total gross unrecognized tax benefit liabilities for the year ended December 31, 2013.

The Company and its subsidiaries are subject to U.S. and Canadian federal income tax laws as well as the income tax laws of multiple state jurisdictions. The major tax jurisdictions in which the Company operates generally provide for a deficiency assessment statute of limitation period of three years and as a result, the Company’s tax years 2010 and forward remain open to examination in those jurisdictions.

During 2007, the Company contracted with a third-party qualified intermediary in order to implement a like-kind exchange tax program. Under the program, dispositions of eligible trucks or trailers and acquisitions of replacement trucks or trailers are made in a form whereby any associated tax gains related to the disposal are deferred. To qualify for like-kind exchange treatment, we exchange, through our qualified intermediary, eligible trucks or trailers being disposed with trucks or trailers being acquired that allows us to generally carryover the tax basis of the trucks or trailers sold. The program is expected to result in a significant deferral of federal and state income taxes. Under the program, the proceeds from the sale of eligible trucks or trailers carry a Company-imposed restriction for the acquisition of replacement trucks or trailers. These proceeds may be disqualified under the program at any time and at the Company’s sole discretion, however income tax deferral would not be available for any sale for which the Company disqualifies the related proceeds. At December 31, 2013, the Company had $623,000 of restricted cash held by the third-party qualified intermediary. At December 31, 2012, the Company had $503,000 of restricted cash held by the third-party qualified intermediary. Restricted cash is accounted for in “Accounts receivable-other”.
