PART I

ITEM 1. BUSINESS

Unless the context requires otherwise, references in this report to “Old Dominion”, the “Company”, “we”, “us” and “our” refer to Old Dominion Freight Line, Inc. and its subsidiary on a consolidated basis.

General

We are a leading less-than-truckload (“LTL”) multi-regional motor carrier providing timely one to five day service among five regions in the United States and next-day and second-day service within these regions. Through our four branded product groups, OD-Domestic, OD-Expedited, OD-Global and OD-Technology, we offer an expanding array of innovative products and services. At December 31, 2004, we provided full-state coverage to 29 of the 40 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 markets and increase our direct coverage to 41 states and our full-state coverage to 31 states in the first quarter of 2005, as a result of the January 2005 selected asset purchase of Wichita Southeast Kansas Transit (“WSKT”). For a discussion of the WSKT asset purchase, see Note 9 to the consolidated financial statements. Old Dominion was founded in 1934 and incorporated in Virginia in 1950.

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, 2004, we increased our number of service centers from 53 to 138 and our states directly served from 21 to 40. We believe that our present infrastructure will enable us to increase the volume of freight moving through our network, or freight density, 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 our customer service, reduce our transit times and minimize our operating costs. In addition to our core LTL services, we provide premium expedited services, container delivery service to and from nine port facilities and distribution services in which we either consolidate LTL shipments for full truckload transport by a truckload carrier or break down full truckload shipments from a truckload carrier into LTL shipments for our delivery.

We combine the rapid transit times of a regional carrier with the geographic coverage of an inter-regional carrier. We believe our transit times are generally faster than those of our principal national competitors in part because of our more efficient service center network, use of team drivers and investment in technology. In addition, our direct service to 40 states and five regions provides 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 a single source to meet their LTL shipping needs.

We provide consistent customer service from a single organization offering our customers information and pricing from one point of contact. Many of our multi-regional competitors that offer inter-regional service do so through independent companies with separate points of contact, 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 regions.

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 dedicate 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.

Table of Contents

In contrast to truckload carriers, LTL carriers require expansive networks of local pickup and delivery service centers, as well as larger hub facilities. Significant capital is required of LTL motor carriers to create and maintain a network of service centers and a fleet of tractors and trailers. The substantial infrastructure spending needed for LTL carriers makes it difficult for new start-up or small operations to effectively compete with established companies.

Service Center Operations

At December 31, 2004, we conducted operations through 138 service center locations, of which we own 68 and lease 70. We operate major breakbulk, or hub, 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. 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. Each service center loads the freight by destination the day it is picked up. Our management reviews the productivity and service performance of each service center on a daily basis in order to maximize quality service.

While we have established primary responsibility for customer service at the local service center level, our customers may access information 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 our corporate office. Our systems offer direct access to information such as freight tracking, shipping documents, rate quotes, rate databases and account activity.

We plan to expand capacity at existing service centers as well as expand the number of service centers geographically as opportunities arise that provide for profitable growth and fit the needs of our customers.

Linehaul Transportation

Our Linehaul Transportation Department is responsible for directing the movement of freight among our service centers. Linehaul dispatchers control the movement of freight among service centers through real-time, 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 use scheduled dispatches, and additional dispatches as necessary, to meet our published service standards. In addition, we lower our cost structure by maintaining flexible work force rules and by using twin 28-foot trailers exclusively in our linehaul operations. Use of twin 28-foot trailers permits us to pick up freight directly from its point of origin to destination with minimal unloading and reloading, which also reduces cargo claims expenses, and twin trailers permit more freight to be hauled behind a tractor than could be hauled if we used one larger trailer.

Tractors, Trailers and Maintenance

At December 31, 2004, we operated 3,430 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 their 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, 2004, we operated a fleet of 13,081 trailers. As we have expanded and our needs for equipment have increased, we have purchased new trailers as well as trailers meeting our specifications from other trucking companies. These purchases of pre-owned equipment, though providing an excellent value, have the effect of increasing our trailer fleet’s average age.

Table of Contents

The table below reflects, as of December 31, 2004, the average age of our tractors and trailers:

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 flow of equipment.

The table below sets forth our capital expenditures for tractors and trailers for the years ended December 31, 2004, 2003 and 2002:

At December 31, 2004, we had major maintenance operations at our service centers in Los Angeles and Rialto, California; Atlanta, Georgia; Des Plaines, Illinois; Indianapolis, Indiana; Jersey City, New Jersey; Greensboro, North Carolina; Columbus, Ohio; Harrisburg, Pennsylvania; Morristown and Memphis, Tennessee; and Dallas, Texas. In addition, eleven other service center locations are equipped to perform routine and preventive maintenance checks and repairs on our equipment.

We have an established scheduled maintenance policy and procedure. 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, 2004, we had a sales staff of 363 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.

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, as necessary, 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. At year-end 2004, our customer base exceeded 60,000 customers. In 2004, our largest customer accounted for approximately 3.5% of revenue and our largest 20, 10 and 5 customers accounted for approximately 22.4%, 15.1% and 10.3% 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. We are the 7^th largest non-unionized LTL carrier in the United States, 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 has 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, which may limit our ability to maintain or increase prices or maintain significant growth.

On February 25, 2005, Yellow Roadway Corporation announced that it entered into a definitive agreement to acquire USF Corporation. These two companies are direct competitors, and the combined enterprise is expected to have annual revenue in excess of $9 billion. The addition of USF Corporation will allow Yellow Roadway to enter the next-day and regional markets, which are among the fastest growing transportation markets, and thereby may enable Yellow Roadway to compete more directly with us for customers.

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. 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 in an effort to reduce costs and transit times. Our principal technologies include:

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 $2,000,000 per occurrence. Cargo claims are self-insured up to $100,000. We also are self-insured for workers’ compensation in certain states and have first dollar or high deductible plans in the other states. The workers’ compensation retention levels for all states range from $250,000 to $1,000,000 depending on the plan year. 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 up to set limits, together with our safety and loss prevention programs, is an effective means of managing insurance costs. We believe that our current insurance coverage is adequate to cover our liability risks.

Fuel Availability and Cost

Our industry depends heavily upon the availability of diesel fuel. In periods of significant price increases, we have implemented a fuel surcharge to offset the additional cost of fuel, which is consistent with our competitors’ practices. However, from time to time, we experience shortages in the availability of fuel at certain locations and have been forced to incur additional expense to ensure adequate supply on a timely basis. Our management believes that our operations and financial condition are susceptible to the same fuel price increases or fuel shortages as those of our competitors. Fuel costs, including fuel taxes, averaged 9.5% of revenue in 2004. Our current fuel surcharge program was implemented in August 1999 and has remained in effect since that time.

Tire Availability

Our industry depends heavily upon the availability of tires. Due to increased demand for tires in the transportation industry, tire manufacturers have recently faced capacity constraints. In response to these constraints, we have obtained commitments from our suppliers to ensure that our needs for 2005 will be met.

Employees

As of December 31, 2004, we employed 8,497 individuals on a full-time basis in the following categories:

As of December 31, 2004, we employed 1,981 linehaul drivers and 2,355 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. 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, 1,609 individuals have graduated from this program, from which we have experienced an annual turnover rate of approximately 9%. 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 2004 were approximately $829,000.

Our management believes that relations with our employees are excellent and there are no employees represented under a collective bargaining agreement. We believe our non-union workforce gives us a significant advantage over unionized LTL carriers. 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. Management’s focus on communication and the continued education, development and motivation of our employees helps to ensure that our relationship with our employees remains excellent.

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 or limits on vehicle weight and size, ergonomics and hours of service. These changes may affect the economics of the industry by requiring changes in operating practices or by influencing the demand for, and the costs of providing services to, shippers.

The DOT issued new Hours of Service Regulations for the transportation industry that became effective January 2, 2004. These new regulations increased the number of hours our drivers can drive from 10 hours to a maximum of 11 hours and defined the maximum number of hours in a workday to 14 hours, measured from the driver’s initial start time. These regulations also increased the minimum required number of hours of rest between work periods from 8 hours to 10 hours. On September 30, 2004, the U.S. Congress voted to extend the current Hours of Service Regulations until no later than

Table of Contents

September 30, 2005, after a July 2004 ruling by the U.S. Court of Appeals for the District of Columbia that vacated those rules in order to allow the DOT adequate time to provide evidence that the new Hours of Service Regulations are safe. In response to the July 2004 U.S. Court of Appeals decision, the Federal Motor Carrier Safety Administration (“FMCSA”) has been reviewing and reconsidering the Hours of Service Regulations and has asked for public comments. On February 9, 2005, the FMCSA Administrator announced that the Bush Administration will recommend to the U.S. Congress that it include the current Hours of Service Regulations in this year’s highway reauthorization legislation.

We believe that the cost of compliance with applicable laws and regulations neither has materially affected nor will 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, among other things, the emission and discharge of hazardous materials into the environment or their presence on or in our properties and vehicles, fuel storage tanks, transportation of certain materials and the discharge or retention of storm water. Under specific 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 2005 or fiscal 2006.

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 the following:

Table of Contents

If our employees were to unionize, our operating costs would increase and our ability to compete would be substantially 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:

These results, and unionization of our workforce generally, could have a materially 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 the geographic reach of our service center network 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:

We cannot assure that we will overcome the risks associated with our growth. If we fail to overcome such 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.

Our information technology systems are subject to certain risks that we cannot control.

Our information systems, including our accounting systems, are dependent upon third-party software, global communications providers, telephone systems and other aspects of technology and Internet infrastructure that are susceptible to failure. Though 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.

Table of Contents

We are exposed to potential risks from recent legislation requiring companies to evaluate their internal control over financial reporting.

Management has concluded that our internal control over financial reporting was effective as of December 31, 2004, in accordance with Section 404 of the Sarbanes-Oxley Act of 2002, based on management’s evaluation under the framework in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. In addition, our auditors have attested to management’s certification, as set forth in its audit report included in this annual report. Management’s evaluation and our auditor’s attestation related to a software platform that we had used through December 31, 2004, but that we had decided in 2003 to replace. The process to convert our old software platform to our new platform occurred during 2004 and was completed on January 1, 2005. Consequently, we must document and test, and management must assess, our internal control over financial reporting under the new software platform during 2005 and in future periods. There can be no assurances that the evaluation required by Sarbanes-Oxley Section 404 in 2005 will not result in the identification of control deficiencies, significant deficiencies or material weaknesses.

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 truck 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 such insurance has risen significantly. 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. 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 in 2004 and 2003 were $92,106,000 and $98,441,000, respectively. We expect our capital expenditures for 2005, including the WSKT selected asset purchase, to be approximately $145,000,000 to $155,000,000. We depend on operating leases, lines of credit, secured equipment financing and cash flow from operations to finance the purchase of tractors, trailers and service centers. If we are unable in the future to raise sufficient capital or borrow sufficient funds to make these purchases, we will be forced to limit our growth and operate our trucks for longer periods of time, which could have a material adverse effect on our operating results.

10

Table of Contents

In addition, our business has significant operating cash requirements. If our cash requirements are high or our cash flow from operations is low during particular periods, we may need to seek additional financing, which may be costly or difficult to obtain. We currently maintain an $80,000,000 unsecured line of credit with lenders consisting of Wachovia Bank, National Association; Bank of America, N.A.; and Branch Banking and Trust Company that will expire in June 2006. We also executed a note purchase agreement during the first quarter of 2005, pursuant to which we issued $50,000,000 of privately-placed senior notes in February 2005 and will issue an additional $25,000,000 of privately-placed senior notes in May 2005. For additional information on these senior notes, see “Liquidity and Capital Resources” included in Item 7.

We may not realize additional revenues or profits from our infrastructure investments in a timely manner or at all.

We have invested, and expect to continue to invest, substantial amounts in building, expanding and upgrading service center facilities. If we are unsuccessful in our strategy for increasing our market share of LTL shipments, we may not realize additional revenues or profits from our infrastructure investments in a timely manner or at all.

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

Fuel is a significant operating expense. We do not hedge against the risk of fuel price increases. Any increase in fuel taxes or fuel prices or any change in federal or state regulations that results in such an increase, to the extent not offset by freight rate increases or fuel surcharges to customers, or any interruption in the supply of fuel, could have a material adverse effect on our operating results. Historically, we have been able to offset significant increases in fuel prices through fuel surcharges to our customers, but we cannot be certain that we will be able to do so in the future. From time to time, we experience shortages in the availability of fuel at certain locations and have been forced to incur additional expense to ensure adequate supply on a timely basis.

Limited supply and increased prices for new equipment may adversely affect our earnings and cash flow.

Investment in new equipment is a significant part of our annual capital expenditures. We may face difficulty in purchasing new equipment due to decreased supply. The price of our equipment may be adversely affected in the future by regulations on newly manufactured tractors and diesel engines. See the discussion below: “We are subject to various environmental laws and regulations, and costs of compliance with, liabilities under, or violations of, existing or future environmental laws or regulations could adversely affect our business.”

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.

We are regulated by 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, safety and fitness of transportation equipment and drivers, driver hours of service, and periodic financial reporting. In addition, the trucking industry is subject to regulatory and legislative changes from a variety of other governmental authorities, which address matters such as increasingly stringent environmental and occupational safety and health regulations or limits on vehicle weight and size, and ergonomics. Regulatory requirements, and changes in regulatory requirements, may affect our business or the economics of the industry by requiring changes in operating practices or by influencing the demand for and the costs of providing transportation services.

We are subject to various environmental laws and regulations, and costs of compliance with, liabilities under, or violations of, existing or future environmental laws or regulations could adversely affect our business.

We are subject to various federal, state and local environmental laws and regulations regulating, among other things, the emission and discharge of hazardous materials into the environment or presence on or in our properties and vehicles, fuel storage tanks, our transportation of certain materials and the discharge or retention of storm water. Under specific 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. Environmental laws have become and are expected to become increasingly more stringent over time, and there can be no assurance that our costs of complying with current or future environmental laws or liabilities arising under such laws will not have a material adverse effect on our business, operations or financial condition.

The Environmental Protection Agency has issued regulations that require progressive reductions in exhaust emissions from diesel engines through 2007. Beginning in October 2002, new diesel engines were required to meet these new emission limits. Some of the regulations require subsequent reductions in the sulfur content of diesel fuel beginning in June 2006 and the introduction of emissions after-treatment devices on newly-manufactured engines and vehicles beginning with model year 2007. These regulations could result in higher prices for tractors and diesel engines and increased fuel and maintenance costs. These adverse effects, combined with the uncertainty as to the reliability of the vehicles equipped with the newly designed diesel engines and the residual values that will be realized from the disposition of these vehicles, could increase our costs or otherwise adversely affect our business or operations.

Our results of operations may be affected by seasonal factors and harsh weather conditions.

Our operations are subject to seasonal trends common in the trucking industry. Our operating results in the first quarter are normally lower due to reduced demand during the winter months. Harsh weather can also adversely affect our performance by reducing demand and reducing our ability to transport freight, which could result in increased operating expenses.

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

The success of our business will continue to depend upon our executive officers. The loss of the services of any of our key personnel could have a material adverse effect.

Our principal shareholders control a large portion of our outstanding common stock.

On March 15, 2005, Earl E. Congdon and John R. Congdon and members of their families and their affiliates beneficially owned 32.5% of the outstanding shares of our common stock. As long as the Congdon family controls a large portion of our voting stock, they will be able to significantly influence the election of the entire Board of Directors and the outcome of all matters involving a shareholder vote. The Congdon family’s interests may differ from other shareholders.

We cannot provide assurances that our acquisitions will be profitable or that they will not negatively impact our business.

Acquisitions have been and continue to be an important part of our growth strategy. However, suitable acquisition candidates may not be available on terms and conditions we find acceptable. In pursuing acquisitions, we compete with other companies, many of which have greater financial and other resources than we do to acquire attractive companies. Even if completed, the following are some of the risks associated with acquisitions that could have a material adverse effect on our business, financial condition and results of operations:

In the aftermath of the September 11, 2001, terrorist attacks on the United States, federal, state and municipal authorities implemented various security measures, including checkpoints and travel restrictions on large trucks. If new security measures disrupt or impede the timing of our deliveries, we may fail to meet the needs of our customers or may incur increased expenses to do so. We cannot assure you that these measures will not have a material adverse effect on our operating results.

Our stock price may be volatile and could decline substantially.

Our common stock has experienced price and volume fluctuations. Many factors may cause the market price for our common stock to decline, including some of the risks enumerated above. In addition, if our operating results fail to meet the expectations of securities analysts or investors in any quarter or securities analysts revise their estimates downward, our stock price could decline.

In the past, companies that have experienced volatility in the market price of their stock have been the subject of securities class action litigation. If we become involved in a securities class action litigation in the future, it could result in substantial costs and diversion of management attention and resources, harming our business.

ITEM 2. PROPERTIES

We own our general office located in Thomasville, North Carolina, consisting of a two-story office building of approximately 160,000 square feet on 23.6 acres of land. We also own service center facilities in Birmingham, Dothan and Huntsville, Alabama; Tucson, Arizona; Little Rock, Arkansas; Bakersfield, Los Angeles and Rialto, California; Denver, Colorado; South Windsor, Connecticut; New Castle, Delaware; Atlanta and Sylvester, Georgia; Jacksonville, Miami, Orlando, Sarasota and Tampa, Florida; Des Plaines and Rock Island, Illinois; Indianapolis, Indiana; Des Moines, Iowa; Kansas City, Kansas; Lexington, Kentucky; Baltimore, Maryland; Boston, Massachusetts; Detroit and Lansing, Michigan; Minneapolis, Minnesota; Jackson and Tupelo, Mississippi; Syracuse, New York; Asheville, Charlotte, Fayetteville, Greensboro, Hickory, Wilmington and Wilson, North Carolina; Cincinnati, Columbus, Dayton and Youngstown, Ohio; Oklahoma City, Oklahoma; Harrisburg and Pittsburgh, Pennsylvania; Providence, Rhode Island; Charleston, Columbia and Greenville, South Carolina; Chattanooga, Memphis, Morristown and Nashville, Tennessee; Amarillo, Dallas, El Paso, Houston, Laredo and Wichita Falls, Texas; Salt Lake City, Utah; Manassas, Martinsville, Norfolk and Richmond, Virginia; and La Crosse, Milwaukee and Wausau, Wisconsin.

We also own ten non-operating properties, all of which are held for lease. Seven of these ten properties are currently leased with lease terms ranging from month-to-month to a lease that expires in June 2005.

We lease 70 of our 138 service centers. These leased facilities are dispersed over the 40 states in which we operate in the Southeast, Northeast, Midwest, South Central and West regions of the country. The length of these leases ranges from month-to-month to a lease that expires in August 2011. We believe that as current leases expire, we will be able to renew them or find comparable facilities without incurring any material negative impact on service to customers or our operating results.

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

Overview

We are a leading less-than-truckload multi-regional motor carrier providing timely one to five day service among five regions in the United States and next-day and second-day service within these regions. Through our four branded product groups, OD-Domestic, OD-Expedited, OD-Global and OD-Technology, we offer an expanding array of innovative products and services. At December 31, 2004, we provided full-state coverage to 29 of the 40 states that we serve 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 markets and increase our direct coverage to 41 states and our full-state coverage to 31 states in the first quarter of 2005, as a result of the January 2005 acquisition of WSKT.

Historically, over 90% of our revenue is derived from transporting LTL shipments for our customers, whose demand for our services is generally tied to the overall health of the U.S. domestic economy. We combine the rapid transit times of a regional carrier with the geographic coverage of an inter-regional carrier. We believe our transit times are generally faster than those of our principal national competitors and we are highly competitive with our principal regional competition.

In analyzing the components of our revenue, we monitor changes and trends in the following key metrics:

Our primary revenue focus is to increase shipment and tonnage growth within our existing infrastructure, generally referred to as increased density, thereby maximizing asset utilization and labor productivity. We measure density over many different functional areas of our operations including revenue per service center, linehaul load factor, pickup and delivery (“P&D”) stops per hour, P&D shipments per hour and platform pounds per hour. We believe continued improvement in density is a key component in our ability to sustain profitable growth.

Table of Contents

The majority of direct costs associated with our business are driver and service center wages and benefits; operating supplies and expenses; and depreciation of our equipment fleet and service center facilities. We gauge our overall success in managing these costs by monitoring our operating ratio, a measure of profitability calculated by dividing total operating expenses by revenue, which also allows industry-wide comparisons with our competition.

We continually upgrade our technological capabilities to improve our customer service and lower our operating costs. This technology provides our customers with visibility of their shipments throughout our systems, while providing key metrics from which we can monitor our processes.

We 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 focus on communication and the continued education, development and motivation of our employees to ensure that our relationships remain excellent.

Market fluctuations in the cost of key components of our cost structure, such as diesel fuel, can affect our profitability. Our tariffs and contracts generally provide for a fuel surcharge as diesel fuel prices increase above stated levels. We are also subject to market changes in insurance rates, and we continue to evaluate our balance of excess insurance coverage and self-insurance to minimize that cost.

Results of Operations

The following table sets forth, for the years indicated, expenses and other items as a percentage of revenue from operations:

2004 Compared to 2003

Key financial and operating metrics for 2004 and 2003 are presented below:

In 2004 and for the third consecutive year, we achieved double-digit growth in revenue, net income and diluted earnings per share. Because our focus in 2004 remained primarily on revenue growth in existing markets, we were successful in increasing our operating density and achieved reductions in our operating ratio to 91.4% from 92.3% in 2003. Increased revenue and improved operating efficiency enabled us to achieve a 41.3% increase in net income and a 39.1% increase in earnings per share, both in excess of our 23.4% growth in revenue. Our earnings per share improvement was achieved despite the dilutive effects of our third quarter 2004 stock offering, which increased our shares outstanding by 736,000 shares, or 3.1%.

Our revenue growth in 2004 was driven primarily by two factors, a 16.7% growth in LTL tonnage coupled with a 5.0% increase in LTL revenue per LTL hundredweight. We believe our tonnage gains are due to overall improvements in the U.S. domestic economy and our ability to attract new customers. In 2004, LTL weight per LTL shipment increased 3.8% over 2003. We believe the increase in LTL weight per LTL shipment indicates greater demand for our customers’ products and a resulting increase in overall shipment size and weight. In addition, we have seen higher year-over-year growth rates in our customer base that is priced through individual contracts. Revenue based on contractual pricing increased to 39.7% of our total revenue in 2004 compared with 37.7% in 2003. We believe the expansion of our service center network and full-state coverage to 29 of those states at year-end 2004 has positioned us to be attractive to larger customers that ship to and from many regions in the country and seek to reduce their number of core carriers. Our contract customers generally offer larger shipments, which increase our average LTL weight per LTL shipment. These customers often have a greater length of haul, which is consistent with our average length of haul increase to 937 miles in 2004 from 926 miles in 2003.

LTL revenue per LTL hundredweight increased to $14.49 from $13.80. Our tariffs and contracts generally provide for a fuel surcharge as diesel fuel prices increase above stated levels. This surcharge is recorded as additional revenue and is intended to offset significant fluctuations in the price of diesel fuel, which is one of the larger components of our operating supplies and expenses. Because of average higher fuel prices in 2004, the fuel surcharge increased to 6.3% of revenue from 4.4% in 2003. Excluding the fuel surcharge, LTL revenue per LTL hundredweight increased 2.9% to $13.57 from $13.19 in 2003, reflecting our ability to marginally improve overall pricing in 2004.

During the year, we opened 12 new service centers. In addition to these openings, we improved our direct service capabilities in Canada and initiated sales operations in Toronto and Montreal. While the expansion of our service center network and improvement in our service capabilities should provide a platform for future growth, these events did not have a significant impact on our annual results.

Density, as measured by increases in tonnage and concentrations of shipments moving through our route structure and service center network, generated efficiencies throughout our operations. As a result, we achieved reductions in salaries, wages and benefits as a percentage of revenue, which decreased to 56.9% in 2004 from 59.4% in 2003.

Driver wages decreased to 22.9% of revenue in 2004 from 24.0% for the prior year. We achieved a 2.0% improvement in P&D shipments handled per hour and a 1.7% increase in our laden load average for the year. We also experienced a similar reduction in platform labor, which decreased to 7.7% of revenue in 2004 from 8.0% for the prior year. Our fringe benefit costs increased slightly to 27.3% of payroll in 2004 from 27.0% for the prior year due primarily to increases in holiday, vacation and other paid time off.

Table of Contents

Operating supplies and expenses increased to 12.2% of revenue in 2004 from 10.8% in 2003. This increase was primarily due to a 56.1% increase in diesel fuel costs, excluding fuel taxes, resulting from increased fuel prices and an 18.5% increase in consumption. We currently do not use diesel fuel hedging instruments; therefore, we are subject to market price fluctuations. Our fuel surcharges, which decrease or are eliminated as fuel prices approach established base levels, effectively offset the increases in diesel fuel prices in 2004.

Insurance and claims expense, primarily consisting of premiums and self-insured costs for auto liability and cargo claims, increased to 3.2% of revenue in 2004 compared to 2.6% in 2003. We choose to self-insure a portion of our auto and cargo claims liabilities and obtain excess insurance coverage for claims above our retention levels. While cargo claims liabilities in 2004 remained relatively constant with 2003 experience, our auto liability claims experience under our retention level increased to 1.3% of revenue for 2004 compared to 0.7% in the prior year. This increase is due to both the number and severity of claims that were incurred during 2004 and to increases in reserves for claims incurred in prior years.

The focus on revenue growth in existing markets has provided opportunities to leverage our investments in property and equipment. As a result, depreciation and amortization expenses decreased to 5.4% of revenue in 2004 from 5.7% in 2003. In addition, building and office equipment rents decreased to 0.9% of revenue in 2004 from 1.1% in the prior year. As a result of greater service center utilization and improved density, our average revenue per service center increased 11.8% over the prior year.

We purchase transportation services from other motor carriers and railroads for linehaul and pickup and delivery services. We also contract with lease operators and lease tractors, trailers and other revenue producing equipment. We utilize these services when there are capacity restraints or imbalances of freight flow within our service center network or when it is economically beneficial. Purchased transportation increased to 3.6% of revenue in 2004 from 3.2% in 2003, primarily as a result of the increased use of purchased linehaul services, which increased to 1.0% of revenue in 2004 from 0.4% of revenue in 2003. We increased our utilization of these linehaul services in 2004 primarily to offset freight imbalances in our longer haul lanes.

Our revenue growth and density improvements in 2004 allowed us to successfully leverage our communication and utilities costs along with general supplies and expenses, which decreased to 4.7% of revenue in 2004 from 5.0% in 2003.

We applied the proceeds of $19,753,000 from our third quarter 2004 stock offering to reduce outstanding debt on our credit facility. At year-end, long-term debt including current maturities was $79,454,000 compared to $97,426,000 at December 31, 2003, a decrease of $17,972,000, or 18.4%. As a result, interest expense for 2004, net of interest income, decreased 13.7% to $5,273,000 from $6,111,000 in 2003. We also capitalized $154,000 more interest during 2004 than the prior year, which also contributed to the decrease in net interest expense.

Our effective tax rate for 2004 was 39.6% compared to 39.1% in 2003.

2003 Compared to 2002

We produced a 17.8% increase in revenue in 2003 coupled with a 49.5% increase in net income for the year. Revenue increased to $667,531,000 from $566,459,000 in 2002, our second consecutive year of double-digit revenue growth and the eleventh in the thirteen years since our initial public offering in 1991. Our operating ratio decreased to 92.3% from 93.6% and net income for 2003 was $27,600,000 compared to $18,462,000 in 2002.

Most of our growth in 2003 can be attributed to market share gains in existing areas of our operations, which increased our density and resulted in lower incremental operating costs. Revenue per service center increased 13.7%, despite opening 9 additional service centers in 2003. These openings accounted for less than 4% of our increase in revenue in 2003, but enabled us to offer full-state coverage to all points in Arkansas, Louisiana and Missouri and increase our full-state coverage from 24 to 27 of the 38 states in which we provide direct service.

Our LTL shipments increased 12.9% over 2002 and LTL tonnage increased 12.1%, both indicators of increased market share and an improving domestic economy. We also continued to benefit from the September 2, 2002, bankruptcy of Consolidated Freightways, a major national LTL carrier and one of our competitors. Our average length of haul increased to 926 miles from 903 in 2002, which is consistent with the longer haul freight that became available after the closure of Consolidated Freightways.

LTL Revenue per LTL shipment increased to $142.57 from $136.50 in 2002, an increase of 4.4%. This was due to a combination of a 5.2% increase in LTL revenue per hundredweight, partially offset by a 0.8% decrease in weight per shipment. Approximately 48% of our revenue was generated from public tariffs, which are generally reviewed on an annual basis with the most recent general price increase occurring on July 3, 2003. The remaining revenue base was generated from contractual agreements, typically one to two years in length, which are renegotiated as they near expiration. While the average LTL weight per LTL shipment was lower in 2003, we have seen consecutive monthly increases in this measurement since April 2003 and we believe this is yet another indicator of an improving economic climate as our customers are moving larger shipments through our network.

Our tariffs and contracts generally provide for a fuel surcharge as diesel fuel prices increase above stated levels. This surcharge is recorded as additional revenue and is intended to offset significant fluctuations in the price of diesel fuel, which is one of the larger components of our operating supplies and expenses. Because of average higher fuel prices in 2003, the fuel surcharge increased to 4.4% of revenue from 3.1% in 2002.

The market share increases we experienced in 2003 generated operating efficiencies and productivity gains throughout our operations, which is reflected in a decrease in our operating ratio to 92.3% from 93.6% in 2002. The benefit of increased freight density was particularly evident in the reduction in salaries, wages and benefits, which decreased to 59.4% of revenue in 2003 from 60.2% in 2002.

P&D wages decreased to 11.9% of revenue from 12.4% in 2002. A portion of these savings resulted from the rollout of our driver hand-held computers, which was completed by year-end 2003. These handheld computers provide direct communication between our drivers, service center personnel and other Old Dominion systems, which results in more efficient routings of our P&D fleet and increased productivity. For the comparable years, P&D shipments handled per hour increased 3.1% and P&D wages per shipment decreased slightly, despite an average hourly wage increase of approximately 2.5%.

Platform wages decreased to 8.0% of revenue in 2003 from 8.2% in 2002. This reduction was due to increased dock productivity partially due to the implementation of our Dock Yard Management system at most of our major facilities by year-end 2003. This system utilizes barcode technology to improve freight visibility throughout our systems and allow for faster and more efficient handling of freight. LTL weight per platform hour and LTL shipments per platform hour, both measures of dock productivity, increased 1.1% and 2.5%, respectively, in 2003 while platform wages per LTL hundredweight increased only 1.7% against an average hourly wage increase of 2.8%.

Reductions in P&D and platform wages were partially offset by an increase in linehaul wages to 12.1% of revenue from 12.0% in 2002. Linehaul miles increased 16.0%, due to increased business levels and a longer average length of haul, and average linehaul wages per mile increased 3.0%. Slight improvements in our linehaul load factor, the weight of shipments loaded onto trailers for each linehaul dispatch, was not sufficient to offset these additional costs.

Our fringe benefit costs increased to 27.0% of payroll in 2003 from 26.5% for the prior year due primarily to increases in workers’ compensation expenses. We self-insure workers’ compensation claims in a range between $250,000 and $1,000,000, depending upon the plan year and the state in which we are operating. We also carry excess coverage for claims in excess of these deductibles. In 2003, the combination of claims expense and insurance premiums was 3.9% of payroll compared to 3.2% in 2002, primarily due to anticipated settlement costs for our self-insured portion.

Diesel fuel costs, excluding fuel taxes, increased 41.7% over 2002 due to a 17.2% increase in consumption and increased costs per gallon. We did not use diesel fuel hedging instruments in 2003 or 2002; therefore, we were subject to market price fluctuations. We believe that our fuel surcharges, which decrease or are eliminated as fuel prices approach base levels, effectively offset the increases in diesel fuel prices in 2003.

Net capital expenditures in 2003 were $98,441,000, which included $45,456,000 for purchases of tractors and trailers in addition to $36,111,000 for purchases of service center facilities or capital improvements to existing service center facilities. These capital expenditures included the purchase of eleven service center facilities auctioned as a result of the September 2002 bankruptcy of Consolidated Freightways. As a result, depreciation and amortization expenses increased to 5.7% of revenue from 5.5% in 2002. As these properties replaced leased facilities, our building and office equipment rents decreased to 1.1% of revenue from 1.3% for the prior year.

Insurance and claims expense, primarily consisting of premiums and self-insured costs for auto liability and cargo claims, decreased to 2.6% of revenue in 2003 compared to 2.9% in 2002. Premiums for excess coverage above our self-insured retention levels generally increased over the prior year as a percentage of revenue. These additional costs were offset by favorable claims experience in our self-insured retention for both auto liability and cargo claims, resulting in a decline in our overall insurance costs in 2003.

Our revenue growth and density improvements in 2003 allowed us to successfully leverage other costs, including communication and utilities, general supplies and expenses, and miscellaneous expenses, which as a group declined to 5.5% of revenue from 6.5% in 2002. Expenses for uncollectible revenue, a component of miscellaneous expenses, decreased to 0.1% of revenue from 0.7% in 2002.

Interest expense for 2003, net of interest income, increased 6.5% to $6,111,000 from $5,736,000 in 2002. By year-end, we borrowed $14,000,000 on our line of credit and an additional $2,650,000 on other debt instruments; however, we made principal payments of $12,447,000 on outstanding debt during the year, resulting in net borrowings of $4,203,000 for 2003. Since average outstanding debt remained relatively constant for the comparable years, the increase in interest expense can be attributed to the decrease in the amount of interest that was capitalized in 2003, which was $178,000 compared to $699,000 in 2002.

Our effective tax rate for 2003 was 39.1% compared to 39.0% in 2002.

Liquidity and Capital Resources

Expansion in both the size and number of service center facilities, our planned tractor and trailer replacement cycle and revenue growth have required continued investment in real estate and equipment. In order to support these requirements, we incurred net capital expenditures of $92,106,000 during 2004. Cash and cash flows generated internally funded approximately 98% of these expenditures. At December 31, 2004, long-term debt including current maturities decreased to $79,454,000 from $97,426,000 at December 31, 2003, primarily due to the application of the proceeds from our third quarter 2004 stock offering to outstanding debt on our credit facility.

We estimate net capital expenditures, including the WSKT selected asset purchase, to be approximately $145,000,000 to $155,000,000 for the year ending December 31, 2005. Of that, approximately $102,000,000 is allocated for the purchase of tractors and trailers; $27,000,000 is allocated for the purchase of service center facilities, construction of new service center facilities or expansion of existing service center facilities; $11,000,000 is allocated for investments in technology; and the balance is allocated for other assets. We plan to fund these capital expenditures primarily through cash flows from operations supplemented by additional borrowings.

Table of Contents

The table below sets forth our net capital expenditures for the years ended December 31, 2004, 2003, and 2002:

We entered into an unsecured revolving credit agreement dated June 30, 2003 with lenders consisting of Wachovia Bank, National Association; Bank of America, N.A.; and Branch Banking and Trust Company, with Wachovia as agent for the lenders. This three-year facility, as amended, consists of $80,000,000 in line of credit commitments from the lenders, all of which are available for revolving loans. In addition, of that $80,000,000 line of credit, $40,000,000 may be used for letters of credit and $10,000,000 may be used for borrowings under Wachovia’s sweep program. The sweep program is a daily cash management tool that automatically initiates borrowings to cover overnight cash requirements up to an aggregate of $10,000,000 or initiates overnight investments for excess cash balances. Revolving loans under the facility bear interest at either: (a) an applicable margin plus the higher of Wachovia’s prime rate or one-half of one percentage point over the federal funds rate (the “Adjusted Base Rate”); or (b) LIBOR plus an applicable margin (the “Adjusted LIBOR Rate”). The applicable margin varies depending upon our ratio of adjusted debt to capital. In the case of the Adjusted Base Rate, the applicable margin ranges from 0% to 0.25%. In the case of the Adjusted LIBOR Rate, the applicable margin ranges from 0.75% to 1.25%. The applicable margin under this agreement for 2004 for the Adjusted Base Rate and the Adjusted LIBOR Rate was 0% and 1.0%, respectively. Revolving loans under the sweep program bear interest at the aggregate rate applicable under the sweep program plus the Adjusted LIBOR Rate.

Quarterly fees ranging from 0.20% to 0.30% are charged on the aggregate unused portion of the facility determined by our ratio of adjusted debt to capital. The applicable rate for the periods under this agreement in 2004 was 0.25%. Quarterly fees are charged on the aggregate undrawn portion of outstanding letters of credit at a rate ranging from 0.75% to 1.25%, which was 1.0% in 2004 as determined by our ratio of adjusted debt to capital. In addition, a quarterly facing fee at an annual rate of 0.125% was charged on the aggregate undrawn portion of outstanding letters of credit.

The June 2003 credit facility contains customary covenants, including financial covenants that require us to observe a maximum ratio of adjusted debt to capital, to maintain a minimum fixed charge coverage ratio and to maintain a minimum consolidated tangible net worth. Our wholly owned subsidiary guaranteed payment of all of our obligations under the facility. Future wholly owned subsidiaries would be required to guarantee payment of all of our obligations under the facility. At December 31, 2004, there was $17,333,000 outstanding on the line of credit facility and there was $31,047,000 outstanding on the standby letter of credit facility.

We had three senior note agreements outstanding totaling $53,714,000 at December 31, 2004. These notes call for periodic principal payments with maturities ranging from 2005 to 2008, of which $16,607,000 is due in 2005. Interest rates on these notes are fixed and range from 6.35% to 7.59%.

Our senior notes and credit agreement limit the amount of dividends that may be paid to shareholders pursuant to certain financial ratios. At December 31, 2004, our credit agreement was the most restrictive and limited the amount of dividends that could be paid to shareholders to the difference between our current tangible net worth, which is defined as shareholders’ equity plus intangible assets, and the sum of $198,000,000 and 50% of cumulative net income since March 31, 2003. We did not declare or pay a dividend on our common stock in 2004, and we have no plans to declare or pay a dividend in 2005.

We have a term loan with principal outstanding of $6,636,000 as of December 31, 2004, which was used to purchase 300 tractors. The term loan consists of 48-month term notes secured by the purchased

22

equipment pursuant to a security agreement with the lender. The notes call for equal monthly payments of principal and interest and mature in 2006, of which $4,141,000 in principal is due within the next 12 months. The interest rates on the notes are fixed and range from 4.21% to 4.39%. The term loan agreement contains customary affirmative and negative covenants. The term notes originally incorporated by reference the financial covenants from our May 2000 credit facility and were amended to incorporate by reference our financial covenants under our June 2003 facility.

With the exception of the line of credit, interest rates are fixed on all of our debt instruments. Therefore, short-term exposure to fluctuations in interest rates is limited to our line of credit facility, which had an outstanding balance of $17,333,000 at December 31, 2004. We do not currently use interest rate derivative instruments to manage exposure to interest rate changes. Also, we do not use fuel hedging instruments, as our tariff provisions and contracts generally allow for fuel surcharges to be implemented in the event that fuel prices exceed stipulated levels.

A significant decrease in demand for our services could limit our ability to generate cash flow and affect profitability. Most of our debt agreements have covenants that require stated levels of financial performance, which if not achieved could cause acceleration of the payment schedules. We do not anticipate a significant decline in business levels or financial performance, and we believe the combination of our existing credit facilities along with our additional borrowing capacity will be sufficient to meet seasonal and long-term capital needs.

On February 25, 2005, we entered into a Note Purchase Agreement with Allstate Life Insurance Company, Allstate Life Insurance Company of New York, New York Life Insurance Company, New York Life Insurance and Annuity Corporation, United of Omaha Life Insurance Company, PRU & Co. (as nominee for Prudential Retirement Insurance and Annuity Company), UMBTRU & Co. (as nominee for Security Benefit Life Insurance Company, Inc.) and Metropolitan Life Insurance Company. Under this agreement, we issued $50,000,000 of privately-placed Series A Senior Notes, Tranche A on February 25, 2005 and will issue an additional $25,000,000 of privately-placed Series A Senior Notes, Tranche B on May 25, 2005 (the “Series A Notes”). The Series A Notes bear an interest rate of 4.68% and a maturity date of February 25, 2015. The Series A Notes call for semi-annual interest payments beginning on August 25, 2005 and seven equal annual principal prepayments commencing on February 25, 2009. The proceeds from this agreement were used to refinance existing indebtedness and for general corporate purposes. The Note Purchase Agreement may also serve as the platform for potential future private note issuances by the Company. The aggregate principal amount of all notes issued pursuant to the Note Purchase Agreement, including the Series A Notes, shall not exceed $300,000,000. The applicable interest rate and payment schedules for any new notes will be determined and mutually agreed upon at the time of issuance.

Pursuant to the February 25, 2005 Note Purchase Agreement, our wholly owned subsidiary executed a Subsidiary Guaranty Agreement, dated as of February 25, 2005, for the benefit of the note holders, which provides that the subsidiary will absolutely, unconditionally and irrevocably guarantee the full payment of all amounts due from the Company and the performance of all of the Company’s obligations, agreements and covenants under the Note Purchase Agreement. As part of the financing, we also entered into a Second Amendment, dated as of February 25, 2005, to our revolving credit agreement, which amended the covenants contained in the credit agreement concerning debt limitations to permit the incurrence of debt under the Series A Notes.

Critical Accounting Policies

In preparing our consolidated financial statements, we apply the following critical accounting policies that affect judgments and estimates of amounts recorded in certain assets, liabilities, revenue and expenses:

Revenue and Expense Recognition - We recognize revenue based upon when our transportation services have been completed in accordance with the bill of lading contract, our general tariff provisions or contractual agreements with our customers. Generally, this occurs when we complete the delivery of a shipment. For transportation services not completed at the end of a reporting period, we use a percentage of completion method to allocate the appropriate revenue to each separate reporting period. Under this method, we develop a factor for each uncompleted shipment by dividing the actual number of days in transit at the end of a reporting period by that shipment’s standard delivery time schedule. This factor is applied to the total revenue for that shipment and revenue is allocated between reporting periods accordingly.

Expenses are recognized when incurred.

Allowance for Uncollectible Accounts - We maintain an allowance for uncollectible accounts for estimated losses resulting from the inability of our customers to make required payments. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required.

Claims and Insurance Accruals - Claims and insurance accruals reflect the estimated unpaid cost of claims, including amounts for claims incurred but not reported, for cargo loss and damage, bodily injury and property damage, workers’ compensation, long-term disability and group health not covered by insurance. These costs are charged to insurance and claims expense except for workers’ compensation, long-term disability and group health, which are charged to employee benefits expense.

We are currently self-insured for bodily injury and property damage claims up to $2,000,000 per occurrence. Cargo loss and damage claims are self-insured up to $100,000. We are self-insured for workers’ compensation in certain states and have first dollar or high deductible plans in the remaining

states with self-insured retention levels ranging from $250,000 to $1,000,000. 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.

Insurers providing excess coverage above retention levels adjust their premiums to cover insured losses and for other market factors. As a result, we periodically evaluate our self-insured retention levels to determine the most cost efficient balance of self-insurance and excess coverage.

In establishing accruals for claims and insurance expenses, we evaluate and monitor each claim individually, and we use factors such as historical experience, known trends and third-party estimates to determine the appropriate reserves for potential liability. We believe the assumptions and methods used to estimate these liabilities are reasonable; however, changes in the severity of previously reported claims, significant changes in the medical costs and legislative changes affecting the administration of our plans could significantly impact the determination of appropriate reserves in future periods.

Goodwill - The excess cost over net assets acquired in connection with acquisitions, or goodwill, is recorded in “Other Assets”. We completed the annual analysis of our intangible assets, required by Statement of Financial Accounting Standard No. 142, Goodwill and Other Intangible Assets (“SFAS 142”), on our annual measurement date of October 1, 2004, and determined that there was no impairment of intangible assets. At December 31, 2004, goodwill totaled $10,648,000.

Property and Equipment - Property and equipment are recorded at cost and depreciated on a straight-line basis over their estimated economic lives. Management uses historical experience, certain assumptions and estimates in determining the economic life of each asset. Periodically, we review property and equipment for impairment to include changes in operational and market conditions, and we adjust the carrying value and economic life of any impaired asset as appropriate. Currently, estimated economic lives for structures are 7 to 30 years; revenue equipment is 4 to 12 years; other equipment is 2 to 20 years; and leasehold improvements are the lesser of the economic life of the leasehold improvement or the life of the lease. The use of different assumptions, estimates or significant changes in the resale market for our equipment could result in material changes in the carrying value of our assets.

Inflation

Most of our expenses are affected by inflation, which generally results in increased operating costs. In response to fluctuations in the cost of petroleum products, particularly diesel fuel, we have implemented a fuel surcharge in our tariffs and contractual agreements. The fuel surcharge is designed to offset the cost of fuel above a base price and increases as fuel prices escalate over the base. For the past three years, the net effect of inflation on our results of operations was minimal.

Related Party Transactions

Family relationships

Each of Earl E. Congdon, John R. Congdon, David S. Congdon, John R. Congdon, Jr. and John B. Yowell are related to one another and serves in various executive management positions and/or on our Board of Directors. In addition, except for Mr. Yowell, each of them beneficially owns more than 5% of our common stock. In 2004, we entered into employment agreements with Earl E. Congdon, John R. Congdon, David S. Congdon and John B. Yowell, which are filed as exhibits to our annual report on Form 10-K. We regularly disclose the amount of compensation that we pay to these individuals in the proxy statement for our annual meeting of shareholders.

Transactions with Old Dominion Truck Leasing, Inc.

Old Dominion Truck Leasing, Inc. (“Leasing”), a North Carolina corporation whose voting stock is owned by the Earl E. Congdon Intangibles Trust, David S. Congdon, Trustee, the John R. Congdon Revocable Trust and members of Earl E. Congdon’s and John R. Congdon’s families, is engaged in the business of purchasing and leasing tractors, trailers and other vehicles. John R. Congdon is Chairman of the Board of Leasing, and Earl E. Congdon is Vice Chairman of the Board of Leasing. Since 1986, we have combined our requirements with Leasing for the purchase of tractors, trailers, equipment, parts, tires and fuel. We believe that, by combining our requirements, we are often able to obtain pricing discounts because of the increased level of purchasing. While this arrangement is beneficial to us, our management believes that the termination of this relationship would not have a material adverse impact on our financial results.

For the years ended December 31, 2004, 2003 and 2002, we charged Leasing $7,000, $39,000 and $14,000, respectively, for vehicle repair, maintenance and other services, which we provide to Leasing at cost plus a negotiated markup. In addition, we charged Leasing $12,000 annually in 2004, 2003 and 2002, for rental of a vehicle maintenance facility located in Chesapeake, Virginia. On March 15, 2003, we entered into an agreement to sublease a vehicle maintenance facility in South Bend, Indiana, to Leasing for which we charged $12,000 in 2004 and $10,000 in 2003.

We purchased $346,000, $266,000 and $297,000 of maintenance and other services from Leasing in 2004, 2003 and 2002, respectively. We believe that the prices we pay for such services are lower than would be charged by unaffiliated third parties for the same quality of work, and we intend to continue to purchase maintenance and other services from Leasing, provided that Leasing’s prices continue to be favorable to us. We also paid Leasing $2,000 for leased equipment in 2004, but did not lease any equipment from Leasing in 2003 or 2002.

On January 4, 2002, we purchased 91 1997 model pickup and delivery trailers from Leasing for an aggregate purchase price of $774,000. We also purchased one trailer from Leasing on May 1, 2003, for a purchase price of $8,000.

Transactions with E & J Enterprises

On July 29, 2002, our Board of Directors approved the purchase of 163 trailers for $1,200 each, or a total of $195,600, from E & J Enterprises (“E&J”), a Virginia general partnership of which Earl E. Congdon, our Chief Executive Officer and Chairman of our Board of Directors, and John R. Congdon, Vice Chairman of our Board of Directors, are each 50% owners. These trailers had been leased to us by E&J since 1988 pursuant to a term lease that converted to a month-to-month lease in 1999. At year-end 2002, we had completed the purchase of 50 of these trailers for a purchase price of $60,000. During the first quarter 2003, we continued to lease the remaining 113 trailers on a month-to-month basis until we completed the purchase of those trailers in March 2003 for a purchase price of $135,600. Also in March 2003, we purchased an additional 10 trailers from E&J for $5,000 each for a total purchase price of $50,000.

On July 29, 2002, our Board of Directors also approved the leasing from E&J of 150 pickup and delivery trailers on a month-to-month basis for $204 per month for each trailer. On December 1, 2003, we purchased these 150 trailers for an aggregate purchase price of $907,000, thereby ending all lease activity with E&J.

There were no lease agreements in effect with E&J during 2004. The total amount paid to E&J for all trailers under lease was $357,000 and $387,000 for 2003 and 2002, respectively.

In December 1988, we sold E&J certain tracts of unimproved land and a vacant service center facility in exchange for a receivable in the amount of $579,798. In December 2003, E&J paid the remaining receivable balance of $195,677, which effectively ended this related party transaction.

Greensboro, NC Service Center Purchase

On October 15, 2002, we purchased a 116-door service center facility and shop located in Greensboro, N.C. for $6,000,000 from an irrevocable trust created for the benefit of the families of Earl E. Congdon, our Chief Executive Officer and Chairman of our Board of Directors, and John R. Congdon, Vice Chairman of our Board of Directors. Prior to our purchase, this property was leased to us with payments totaling $285,000 in 2002. The purchase of this property ended all related party transactions between this trust and the Company.

Disposition of Certain Split Dollar Life Insurance Policies

Prior to December 31, 2003, five split-dollar life insurance agreements to which we were a party terminated. Two of these agreements involved policies administered by Aurora Life Insurance Company. One policy insured the life of Earl E. Congdon and the second insured the life of John R. Congdon. Each policy was owned by the wife of the insured. The owners assigned their interests in the policies to us as payment in full for any obligations owed by them pursuant to the split dollar agreements. As a result of the assignments, we currently own both policies and currently hold them as key man life insurance on Earl. E. Congdon and John R. Congdon.

A third split-dollar agreement involved a policy administered by The Prudential Insurance Company of America insuring the joint lives of Earl E. Congdon and Kathryn Congdon. The policy was owned by Earl Congdon’s children. Under the Prudential split-dollar agreement, the owners had the right to terminate the split-dollar agreement upon payment to us of the total amount of premiums paid by us on the policy less any amounts previously reimbursed. In exercise of that right, the owners terminated the split-dollar agreement in December 2003 and paid to us $595,137. All of this amount represented premiums previously advanced on the insured’s behalf. We no longer own any interest in the Prudential policy.

The final two split-dollar agreements involved policies administered by American General Life of Houston, Texas. One policy insured the joint lives of Earl E. Congdon and Kathryn Congdon and the second insured the joint lives of Jack Congdon and Natalie Congdon. Each policy was owned by a family limited partnership. Under each American General split-dollar agreement, the owners had the right to terminate the split-dollar agreement upon payment to us of the total amount of premiums paid by us on the policy less any amounts previously reimbursed. In exercise of that right, the owner of the American General split-dollar agreement for Earl and Kathryn Congdon terminated that agreement and in December 2003 paid to us $1,367,678 and the owner of the American General split-dollar agreement for Jack and Natalie Congdon terminated that agreement and paid to us $1,373,626. All of these amounts represented premiums previously advanced on the insured’s behalf. We no longer own any interest in the American General policies.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk represents the risk of loss that may impact the consolidated financial position, results of operations and cash flows due to adverse changes in financial market prices and rates.

We are exposed to interest rate risk directly related to our bank credit lines, which have variable interest rates. The average principal balance and effective interest rate under this agreement in 2004 was $22,472,000 and 2.48%, respectively. A 100 basis point increase in the average interest rate on this agreement would have no material effect on our operating results. We have established policies and procedures to manage exposure to market risks and use major institutions that are creditworthy to minimize credit risk.

We are also exposed to commodity price risk related to diesel fuel prices and have established policies and procedures to manage our exposure to such risk.

For further discussion related to these risks, see Note 2 to the consolidated financial statements and “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources” included in Item 7.
