General

We are a leading less-than-truckload (“LTL”) multi-regional motor carrier providing one-to-five day service among five regions in the United States and next-day and second-day service within these regions. We operate as one business segment and offer an expanding array of innovative products and services through our four branded product groups, OD-Domestic, OD-Expedited, OD-Global and OD-Technology. At December 31, 2006, we provided full-state coverage to 37 of the 47 states that we served directly within the Southeast, South Central, Northeast, Midwest and West regions of the country. Through marketing and carrier relationships, we also provided service to and from the remaining states as well as international services around the globe. We plan to continue to expand our service center network, as opportunities arise, to achieve our strategic goal of providing full-state coverage throughout the continental United States. These additions should also provide a platform for future growth and ensure that our service center network has sufficient capacity.

We have grown substantially over the last several years through strategic acquisitions and internal growth. Prior to 1995, we provided inter-regional service to major metropolitan areas from, and regional service within, the Southeast region of the United States. Since 1995, we have expanded our infrastructure to provide next-day and second-day service within four additional regions as well as expanded inter-regional service among those regions. From 1995 through December 31, 2006, we increased our number of service centers from 53 to 182 and our states directly served from 21 to 47. We believe that our present infrastructure will enable us to increase freight density, which is to increase the volume of freight moving through our network, and thereby improve our profitability.

We are committed to providing our customers with high quality service. We are continually upgrading our technological capabilities to improve customer service, reduce our transit times and minimize our operating costs. In addition to our core LTL services, we provide other specialized services including premium expedited services, truckload services, truckload brokerage services, logistical solutions, container delivery service to and from ten port facilities and distribution services in which we either consolidate LTL shipments for full truckload transport by a truckload carrier or convert full truckload shipments from a truckload carrier into LTL shipments for our delivery.

We provide consistent customer service from a single organization offering our customers information and pricing from one point of contact. Our multi-regional competitors that offer inter-regional service typically do so through independent companies or with separate points of contact within different operating segments of the

company, which can result in inconsistent service and pricing, as well as poor shipment visibility. Our integrated structure allows us to offer our customers consistent and continuous service across all areas of operations and service products.

Old Dominion was founded in 1934 and incorporated in Virginia in 1950. Please refer to the Balance Sheets and Statements of Operations included in Item 8 of this report for information regarding our total assets, revenue from operations and net income.

Our Industry

Trucks provide transportation services to virtually every industry operating in the United States and generally offer higher levels of reliability and faster transit times than other surface transportation options. The trucking industry is comprised principally of two types of motor carriers: truckload and LTL. Truckload carriers generally provide an entire trailer to one customer from origin to destination. LTL carriers pick up multiple shipments from multiple customers on a single truck and then route the goods through service centers where freight may be transferred to other trucks with similar destinations for delivery.

In contrast to truckload carriers, LTL motor carriers require expansive networks of local pickup and delivery service centers, as well as larger breakbulk, or hub, facilities. The significant capital that LTL motor carriers must commit to create and maintain a network of service centers and a fleet of tractors and trailers makes it difficult for new start-up or small operations to effectively compete with established companies. In addition, successful LTL motor carriers generally employ a high level of technology to provide information to customers and to reduce operating costs.

Service Center Operations

At December 31, 2006, we conducted operations through 182 service center locations, of which we own 88 and lease 94. We operate major breakbulk facilities in Atlanta, Georgia; Rialto, California; Indianapolis, Indiana; Greensboro, North Carolina; Harrisburg, Pennsylvania; Memphis and Morristown, Tennessee; and Dallas, Texas, while using some smaller service centers for limited breakbulk activity in order to serve next-day markets. Our service centers are strategically located in five regions of the country to provide the highest quality service and minimize freight rehandling costs.

Each of our service centers is responsible for the pickup and delivery of freight for its service area. Each service center loads outbound freight by destination the day it is picked up. All inbound freight received by the service center in the evening or during the night is scheduled for local delivery the next business day, unless a customer requests a different delivery schedule. Our management reviews the productivity and service performance of each service center on a daily basis to ensure quality service and efficient operations.

While we have established primary responsibility for customer service at the local service center level, our customers may access information and initiate transactions through several different gateways such as our website, electronic data interchange, automated voice response systems, automated fax systems or through our customer service department located at the corporate office. Our systems offer direct access to information such as freight tracking, shipping documents, rate quotes, rate databases and account activity.

Linehaul Transportation

Linehaul dispatchers control the movement of freight among service centers through integrated freight movement systems. We also utilize load-planning software to optimize efficiencies in our linehaul operations. Our senior management continuously monitors freight movements, transit times, load factors and other productivity measurements to ensure that we maintain our highest levels of service and efficiency.

We utilize scheduled routes, and additional linehaul dispatches as necessary, to meet our published service standards. In addition, we lower our cost structure by maintaining flexible work force rules and by primarily

using twin 28-foot trailers exclusively in our linehaul operations. The use of twin 28-foot trailers permits us to transport freight directly from its point of origin to destination with minimal unloading and reloading, which also reduces cargo claims expenses. We also utilize long-combination vehicles, such as triple 28-foot trailers and combinations of 48-foot and 28-foot trailers, in states where permitted. Twin trailers and long-combination vehicles permit more freight to be hauled behind a tractor than could be hauled by one larger trailer.

Tractors, Trailers and Maintenance

At December 31, 2006, we operated 4,643 tractors. We generally use new tractors in linehaul operations for approximately three to five years and then transfer those tractors to pickup and delivery operations for the remainder of the assets’ useful lives. In a number of our service centers, tractors perform pickup and delivery functions during the day and linehaul functions at night to maximize tractor utilization.

At December 31, 2006, we operated a fleet of 17,915 trailers. We primarily purchase new trailers for our operations; however, we occasionally purchase pre-owned equipment meeting our specifications from other trucking companies.

We have also acquired tractors and trailers through our acquisition of business assets from other carriers. The purchase of pre-owned equipment can provide an excellent value, but can increase our fleet’s average age. The table below reflects, as of December 31, 2006, the average age of our tractors and trailers:

Type of equipment (categorized by primary use)

  

Number

of units

  

Average

age

Linehaul tractors

   2,743    1.8

Pickup and delivery tractors

   1,900    6.9

Pickup and delivery trucks

   66    3.0

Linehaul trailers

   13,122    7.7

Pickup and delivery trailers

   4,793    11.2


We develop certain specifications for tractors and trailers, the production and purchase of which are negotiated with several manufacturers. These purchases are planned well in advance of anticipated delivery dates in order to accommodate manufacturers’ production schedules. We believe that there is sufficient capacity among suppliers to ensure an uninterrupted supply of equipment to support our operations and planned growth.

The table below sets forth our capital expenditures for tractors and trailers for the years ended December 31, 2006, 2005 and 2004. Our capital expenditures for tractors and trailers in 2006 provided the capacity to support our continued growth and geographic expansion and, to a lesser extent, to replace equipment as part of our normal replacement cycle.

     Year ended December 31,

(In thousands)

   2006    2005    2004

Tractors

   $ 59,759    $ 50,457    $ 35,932

Total

   $ 108,968    $ 103,406    $ 56,819
                    


At December 31, 2006, we had major maintenance operations at our service centers in Los Angeles and Rialto, California; Denver, Colorado; Atlanta, Georgia; Chicago, Illinois; Indianapolis, Indiana; Parsons, Kansas; Jersey City, New Jersey; Greensboro, North Carolina; Columbus, Ohio; Harrisburg, Pennsylvania; Morristown and Memphis, Tennessee; Dallas, Texas; and Salt Lake City, Utah. In addition, nine other service center locations are equipped to perform routine and preventive maintenance and repairs on our equipment.

We have established maintenance policies and procedures. Linehaul tractors are routed to appropriate maintenance facilities at designated mileage or time intervals, depending upon how the equipment was utilized. Pickup and delivery tractors and trailers are scheduled for maintenance every 90 days.

Marketing and Customers

At December 31, 2006, we had a sales staff of 428 employees. We compensate our sales force, in part, based upon revenue generated, Company and service center profitability and on-time service performance, which we believe helps to motivate our employees to achieve our service, growth and profitability objectives.

We utilize a computerized freight costing model to determine the price level at which a particular shipment of freight will be profitable. We can modify elements of this freight costing model to simulate the actual conditions under which the freight will be moved. We also compete for business by participating in bid solicitations. Customers generally solicit bids for relatively large numbers of shipments for a period of one to two years, and typically choose to enter into contractual arrangements with a limited number of motor carriers based upon price and service.

Revenue is generated from many customers and locations across the United States and North America. In 2006, our largest customer accounted for approximately 2.9% of revenue and our largest 20, 10 and 5 customers accounted for approximately 22.8%, 15.3% and 9.6% of our revenue, respectively. For each of the previous three years, less than 5% of our revenue was generated from international services. We believe the diversity of our revenue base helps protect our business from adverse developments in a single geographic region and the reduction or loss of business from a single customer.

Competition

The transportation industry is highly competitive on the basis of both price and service. At December 31, 2006, we were the seventh largest LTL carrier in the United States, as measured by revenue. We compete with regional, inter-regional and national LTL carriers and, to a lesser extent, with truckload carriers, small package carriers, airfreight carriers and railroads. Competition is based primarily on personal relationships, price and service. We believe that we are able to compete effectively in our markets by providing high quality and timely service at competitive prices.

We believe our transit times are generally faster than those of our principal national competitors. We believe this performance is due in part to our more efficient service center network, use of team drivers and investment in technology. In addition, we provide greater geographic coverage than most of our regional competitors. We believe our diversified mix and scope of regional and inter-regional services enable us to provide our customers with a single source to meet their LTL shipping needs and provides us with a distinct advantage over our regional, multi-regional and national competition.

We also believe our non-union workforce gives us a significant advantage over our unionized LTL competition. Advantages of our workforce include flexible hours and the ability of our employees to perform multiple tasks, which we believe result in greater productivity, customer service, efficiency and cost savings.

We compete with several larger transportation service providers, each of which may have more equipment, a broader coverage network and a wider range of services than we do. Our larger competitors also have greater financial resources and, in general, the ability to reduce prices to gain business, especially during times of reduced growth rates in the economy. This could potentially limit our ability to maintain or increase prices or maintain significant growth.

Seasonality

Our tonnage levels and revenue mix are subject to seasonal trends common in the motor carrier industry. Financial results in the first quarter are normally lower due to reduced shipments during the winter months. Harsh winter weather can also adversely impact our performance by reducing demand and increasing operating expenses. Freight volumes typically build to a peak in the third quarter and early fourth quarter, which generally result in improved operating margins.

Technology

We continually upgrade our technological capabilities, and we provide access to our systems through multiple gateways that offer our customers maximum flexibility and immediate access to information. We also employ freight handling systems and logistics technology to reduce costs and transit times. Our principal technologies include:

  •  

www.odfl.com. We continuously update our web site with current information, including service products, coverage maps, financial data, news releases, corporate governance matters, employment opportunities and other information of importance to our customers, investors and employees. Customers may also use our website to, among other things: receive rate estimates; schedule pickups; trace shipments; check transit times; and view or print shipping documents. We make available, free of charge on our web site, our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and amendments to these reports filed or furnished pursuant to Section 13(a) of the Securities Exchange Act of 1934 as soon as reasonably practicable after we electronically file these reports with, or furnish them to, the Securities and Exchange Commission.   •  

odfl4me.com. Customers may also manage their shipping needs from their desktops by registering on the secure area of our web site, odfl4me.com, which provides access to: enhanced shipment tracing; customizable reports; document archives; on-line cargo claims processing; interactive bills of lading; and customized rate estimates for customer-specific pricing programs.   •  

Interactive Voice Response (IVR). Through our IVR telephone system, callers can trace shipments, develop rate estimates and access our fax server to retrieve shipping documents such as delivery receipts and bills of lading.   •  

Electronic Data Interchange (EDI) . For our customers who prefer to exchange information electronically, we provide a number of EDI options with flexible formats and communication alternatives. Our customers can transmit or receive invoices, remittance advices, shipping documents and shipment status information, as well as other customized information.   •  

Radio Frequency Identification (RFID) System. Our automated arrival/dispatch system monitors equipment location and freight movement throughout our system. Transponders are attached to the equipment in our fleet to enable readers to automatically record arrivals and departures, eliminating the need for manual entry and providing real-time freight tracing capabilities for our customers and our employees.   •  

Dock Yard Management (DYM) System. The DYM system records the status of shipments moving within our freight handling system through a network of handheld and fixed mounted computers on our freight docks, switching tractors and forklifts. Each barcoded shipment is monitored by these devices, which provides for real-time tracing and freight management.   •  

Handheld Computer System . Handheld computers provide direct communication to our systems and allow our drivers to capture information during pickups and deliveries, including individual pieces and weights as well as origin and destination shipping points. Timely pickup information allows for better direct loading and efficient scheduling of linehaul operations and enhances real-time information for our customers’ visibility of their supply chain.   •  

Pickup and Delivery Optimation System. This mapping system is utilized by our service centers to improve the efficiency of pickup and delivery (“P&D”) routes. The optimization of our P&D routes improves the efficiency of our operations, reduces costs and reduces transit times. In addition, this system enhances labor productivity by determining proper staffing and providing the most efficient freight loading patterns at our service centers. Insurance

We carry significant insurance with third-party insurance carriers and we self-insure a portion of this risk. We are currently self-insured for bodily injury and property damage claims up to $2,750,000 per occurrence. This self-insured retention level was increased from $2,500,000 during the previous plan year ended March 30, 2006. Cargo loss and damage claims are self-insured up to $100,000 per occurrence. We are exposed to workers’ compensation claims up to $1,000,000 per occurrence, through either self-insurance or insurance deductibles, for the states in which we operate. Group health claims are self-insured up to $300,000 per occurrence and long-term disability claims are self-insured to a maximum per individual of $3,000 per month.

We believe that our policy of self-insuring a portion of our risk, together with our safety and loss prevention programs, is an effective means of managing insurance costs. We also believe that our current insurance coverage is adequate to cover our liability risks.

Diesel Fuel Availability and Cost

Our industry depends heavily upon the availability of diesel fuel. From time to time, we may experience shortages at certain locations and have been forced to incur additional expense to ensure adequate supply on a timely basis to prevent a disruption to our service schedules. We have experienced higher diesel fuel costs in recent years and, as a result, implemented a fuel surcharge program in August 1999 that has remained in effect since that time. Our fuel surcharges, which are generally indexed to the U.S. Department of Energy’s published fuel prices, were implemented to offset the additional cost of diesel fuel and are consistent with our competitors’ practices. Our management believes that our operations and financial condition are susceptible to the same diesel fuel price increases or shortages as those of our competitors. Diesel fuel costs, including fuel taxes, totaled 13.2% of revenue in 2006.

Employees

As of December 31, 2006, we employed 10,762 individuals on a full-time basis in the following categories:

Category
   Number of
employees


Drivers
   5,487

Platform
   1,976

Fleet technicians
   333

Sales
   428

Salaried, clerical and other
   2,538

As of December 31, 2006, we employed 2,573 linehaul drivers and 2,914 pickup and delivery drivers. All of our drivers are selected based upon driving records and experience. Drivers are required to pass drug tests and have a current United States Department of Transportation (“DOT”) physical and a valid commercial driver’s license prior to employment. Once employed, drivers are required to obtain and maintain hazardous materials endorsements to their commercial driver’s licenses. Drivers are also required to take drug and alcohol tests periodically, by random selection.

To help fulfill driver needs, we offer qualified employees the opportunity to become drivers through the “Old Dominion Driver Training Program.” Since its inception in 1988, 2,125 individuals have graduated from this program, from which we have experienced an annual turnover rate of approximately 7%. We believe our driver training and qualification programs have been important factors in improving our safety record. Drivers with safe driving records are rewarded with bonuses of up to $1,000 annually. Driver safety bonuses paid during 2006 were $996,000.

Our focus on communication and the continued education, development and motivation of our employees helps to ensure that our relationship with our employees remains excellent. There are no employees represented under a collective bargaining agreement, which we believe is an important factor in our continued success.

Governmental Regulation

We are regulated by the Surface Transportation Board, an agency within the DOT, and by various state agencies. These regulatory authorities have broad powers, generally governing matters such as authority to engage in motor carrier operations, hours of service, certain mergers, consolidations and acquisitions, and periodic financial reporting. The trucking industry is subject to regulatory and legislative changes, such as increasingly stringent environmental and occupational safety and health regulations, limits on vehicle weight and size, ergonomics and hours of service. These changes may affect the economics of our industry by requiring changes in operating practices, increasing our cost and influencing the demand for our services.

We believe that the cost of compliance with applicable laws and regulations has not and will not materially affect our results of operations or financial condition.

Environmental Regulation

We are subject to various federal, state and local environmental laws and regulations that focus on the transportation of certain materials, the discharge or retention of storm water and the emission and discharge of hazardous materials into the environment or their presence on or in our properties, vehicles and fuel storage tanks. Under certain environmental laws, we could also be held responsible for any costs relating to contamination at our past or present facilities and at third-party waste disposal sites. We do not believe that the cost of future compliance with environmental laws or regulations will have a material adverse effect on our operations, financial condition, competitive position or capital expenditures for the remainder of fiscal 2007 or fiscal 2008.

ITEM 1A. RISK FACTORS

In addition to the factors discussed elsewhere in this report, the following are some of the important factors that could cause our actual results to differ materially from those projected in any forward-looking statements:

We operate in a highly competitive industry, and our business will suffer if we are unable to adequately address potential downward pricing pressures and other factors that may adversely affect our operations and profitability.

Numerous competitive factors could impair our ability to maintain our current profitability. These factors include, but are not limited to, the following:

  •  

we compete with many other transportation service providers of varying sizes, some of which may have more equipment, a broader coverage network, a wider range of services, greater capital resources or have other competitive advantages;   •  

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

many customers reduce the number of carriers they use by selecting “core carriers” as approved transportation 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 prices or result in the loss of some business to competitors;   •  

the trend towards consolidation in the ground transportation industry may create other large carriers with greater financial resources and other competitive advantages relating to their size;   •  

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

competition from non-asset-based logistics and freight brokerage companies may adversely affect our customer relationships and pricing policies. If our employees were to unionize, our operating costs would increase and our ability to compete would be impaired.

None of our employees are currently represented by a collective bargaining agreement. However, from time to time there have been efforts to organize our employees at various service centers. We can make no assurance that our employees will not unionize in the future, which could in turn have a material adverse effect on our operating results because:

  •  

some shippers have indicated that they intend to limit their use of unionized trucking companies because of the threat of strikes and other work stoppages;   •  

restrictive work rules could hamper our efforts to improve and sustain operating efficiency;   •  

a strike or work stoppage would hurt our profitability and could damage customer and employee relationships; and   •  

an election and bargaining process would distract our time and attention from our overall objectives and impose significant expenses. These results, and unionization of our workforce generally, could have a material adverse effect on our business, financial condition and results of operations.

If we are unable to successfully execute our growth strategy, our business and future results of operations may suffer.

Our growth strategy includes increasing the volume of freight moving through our existing service center network, selectively expanding our geographic footprint and broadening the scope of our service offerings. In connection with our growth strategy, we have purchased additional equipment, expanded and upgraded service centers, hired additional personnel and increased our sales and marketing efforts, and expect to continue to do so. Our growth strategy exposes us to a number of risks, including the following:

  •  

geographic expansion and acquisitions require start-up costs that could expose us to temporary losses;   •  

growth through acquisition could require us to temporarily match existing freight rates of the acquiree’s markets, which may be lower than the rates that we would typically charge for our services;   •  

growth and geographic expansion is dependent on the availability of real estate. Shortages of suitable real estate may limit our geographic expansion and might cause congestion in our service center network, which could result in increased operating expenses;   •  

growth may strain our management, capital resources, information systems and customer service;   •  

hiring new employees may increase training costs and may result in temporary inefficiencies until the employees become proficient in their jobs; and   •  

expanding our service offerings may require us to enter into new markets and encounter new competitive challenges. We cannot assure that we will overcome the risks associated with our growth. If we fail to overcome those risks, we may not realize additional revenue or profits from our efforts, we may incur additional expenses and therefore our financial position and results of operations could be materially and adversely affected.

Difficulty in attracting drivers could affect our profitability.

Competition for drivers is intense within the trucking industry, and we periodically experience difficulties in attracting and retaining qualified drivers. Our operations may be affected by a shortage of qualified drivers in the future, which could cause us to temporarily under-utilize our fleet, face difficulty in meeting shipper demands

and increase our compensation levels for drivers. If we encounter difficulty in attracting or retaining qualified drivers, our ability to service our customers and increase our revenue could be adversely affected.

Insurance and claims expenses could significantly reduce our profitability.

We are exposed to claims related to cargo loss and damage, property damage, personal injury, workers’ compensation, long-term disability and group health. We carry significant insurance with third-party insurance carriers, the cost of which has risen significantly in recent years. To offset, in part, the significant increases we have experienced, we have elected to increase our self-insured retention levels for most of our risk exposures. If the number or severity of claims for which we are self-insured increases, or we are required to accrue or pay additional amounts because the claims prove to be more severe than our original assessment, our operating results would be adversely affected. In addition, insurance companies require us to obtain letters of credit to collateralize our self-insured retention. If these requirements increase, our borrowing capacity could be adversely affected.

Our business is subject to general economic factors that are largely out of our control.

Economic conditions may adversely affect our customers’ business levels, the amount of transportation services they need and their ability to pay for our services. Customers encountering adverse economic conditions represent a greater potential for bad debt losses, which may require us to increase our reserve for bad debt. In addition, because we self-insure a substantial portion of our group health expense, increases in healthcare costs and pharmaceutical expenses can adversely affect our financial results. Our results also may be negatively affected by increases in interest rates, which increase our borrowing costs and can negatively affect the level of economic activity by our customers and thus our freight volumes.

We have significant ongoing cash requirements that could limit our growth and affect our profitability if we are unable to obtain sufficient financing.

Our business is highly capital intensive. Our net capital expenditures, including the acquisition of business assets, in 2006 and 2005 were $212,886,000 and $160,488,000, respectively. We expect our capital expenditures for 2007 to be approximately $245,000,000 to $255,000,000. The increase
