PART I

Item 1. Business

General

Covance Inc. is a leading drug development services company providing a wide range of early-stage and late-stage product development services on a worldwide basis primarily to the pharmaceutical, biotechnology and medical device industries. We also provide laboratory testing services to the chemical, agrochemical and food industries. We believe Covance is one of the world's largest drug development services companies, based on annual net revenues, and one of a few that are capable of providing comprehensive global product development services. Covance maintains offices in more than 20 countries.

Business Strategy

Drug development services companies like Covance typically derive substantially all of their revenue from the research, development and marketing expenditures of the pharmaceutical, biotechnology and medical device industries. We believe outsourcing of these services has increased in the past and will increase in the future because of several factors, including: pressures to contain costs, limitations on internal capacity, the need for faster development time for new drugs, research in multiple countries simultaneously, stringent government regulation and expertise that customers lack internally. We believe the investment and amount of time required to develop new drugs has been increasing, and that these trends create opportunities for companies that can help make the process of drug development more efficient.

Our strategy is to provide services that will generate high-quality and timely data in support of new drug approval or use expansion. We do this by developing and delivering innovative high-quality services that apply science and technology and global reach to capture, manage and integrate a vast array of drug development data. In certain service areas, such as toxicology, an increasing portion of our business is being provided through strategic, dedicated laboratory testing services contracts, in which our clients commit to purchasing a specific dollar amount of services in exchange for guaranteed access to a portion of our facilities. This arrangement benefits our customers by guaranteeing them long-term capacity and infrastructure to run their preclinical studies, and benefits Covance by allowing us to more efficiently utilize our capacity and resources.

Operational Excellence. Our goal is to deliver consistently outstanding service to our clients on a global scale through our platform focused on people, process and clients. As a scientific services company, people are integral to our success. We work to recruit, develop and retain talented people through our "Compelling Offer" program which is designed to provide and encourage highly qualified people to initiate and build a career at Covance. We aim to enhance the effectiveness of these people with superior processes to efficiently deliver a high level of client service. Among other tools, we use Six Sigma to optimize our processes to increase our cost competitiveness, eliminate variability in our client service levels and build competitive advantage. Finally, we seek to leverage consistently outstanding client service by building strategic relationships with our clients that drive growth and help sustain our competitive advantage. Across our People, Process and Clients platform, we seek to utilize technology to augment the talent of our people, to automate robust processes, and to link us more closely to our clients via proprietary systems such as StudyTracker®, LabLink and Trial Tracker®.

Global Reach. We believe that it is important to provide a broad range of drug research and development services on a global basis. We have offices, regional monitoring sites and laboratories in more than 50 locations in more than 20 different countries and conduct field work in many other countries. We believe we are a leader among drug development services companies in our ability to support large, global clinical trial programs.

Acquisitions. In addition to internal development of services, we consider strategic acquisitions that are complementary to our existing services and that expand our ability to serve our clients. While we cannot exclude the possibility that we may opportunistically seek to take advantage of other situations, we generally expect acquisitions to enhance our existing services either qualitatively or geographically or to add new services that can be integrated with our existing services. In 2006 and 2005, respectively, we enhanced our preclinical pharmacology service offering with the acquisitions of clinical pharmacology sites of Radiant Research Inc. ("Radiant") and GFI Clinical Services ("GFI"), and in 2006 we enhanced our research products antibody services offering with the acquisition of Signet Laboratories, Inc. ("Signet").

Services

The services we provide constitute two segments for financial reporting purposes: (1) early development services, which includes preclinical services and clinical pharmacology services, and (2) late-stage development services, which includes central laboratory, clinical development, periapproval and market access services. Although each segment has separate services within it, they can be and increasingly are combined in integrated service offerings and we believe clients increasingly are interested in the opportunities for such combined services.

Early Development

Preclinical Services

Our preclinical services include toxicology services, pharmaceutical chemistry and related services. Our preclinical area has been a source of innovation by introducing new technologies for client access to data such as StudyTracker®, electronic animal identification, multimedia study reports and animal and test tube measures of induced cell proliferation or reproduction. StudyTracker® is an internet-based client access product which allows customers of toxicology, bioanalytical, metabolism and reproductive and developmental toxicology services to review study data and schedules on a near real-time basis. We have laboratories in locations which include Madison, Wisconsin and Vienna, Virginia in the United States and Harrogate, United Kingdom and Muenster, Germany in Europe. We also have bioanalytical laboratories in the United States in Indianapolis, Indiana and Chantilly, Virginia, and an administrative and a sales office in Tokyo, Japan. In 2004, we announced major expansions to each of our Madison, Wisconsin and Harrogate, United Kingdom facilities. The Harrogate expansion opened for studies in the fourth quarter of 2005 and in Madison the new expansion was brought online in the first quarter of 2006. In 2007, Covance completed a significant expansion of its Germany facility and opened a nutritional chemistry laboratory in Singapore. Also in 2007, Covance purchased a partially constructed manufacturing facility on a 47 acre property in Prince William County, Virginia, which we plan to transform into an early drug development laboratory offering safety testing and chemistry analysis services. Covance is also building an early development facility in Chandler, Arizona.

Toxicology. Our preclinical toxicology services include in vivo toxicology studies, which are studies of the effects of drugs in animals, and genetic toxicology studies, which include studies of the effects of drugs on chromosomes, as well as on genetically modified mice. We offer immunotoxicology services in which we assess the impact of drugs or chemicals on the structure and function of the immune system. Our immunotoxicology and cell culture laboratory features online data capture capabilities and instrumentation monitoring systems that are designed to be compliant with Good Laboratory Practices.

Pharmaceutical and Nutritional Chemistry. In our pharmaceutical chemistry services, we determine the metabolic profile and bioavailability of drug candidates. We also provide laboratory testing services to the chemical, agricultural chemical and food industries. We offer a complete range of services to agricultural chemical manufacturers to determine the potential risk to humans, animals and the environment from plant protection products such as pesticides. We also offer a broad range of services to the food and nutriceutical industries, including nutritional analysis and nutritional content fact labels.

Research Products. We provide custom polyclonal and monoclonal antibody services for research purposes and purpose-bred animals for biomedical research. In May 2006, we expanded our offerings in monoclonal antibodies with the purchase of Signet of Dedham, Massachusetts for cash payments totaling $9.1 million. Signet was a leading provider of monoclonal antibodies used in the research of cancer, and infectious and other diseases. The purpose-bred research animals we provide are required by pharmaceutical and biotechnology companies, university research centers and contract research organizations as part of required preclinical animal safety and efficacy testing. Through a variety of processes, technology and specifically constructed facilities, we provide purpose-bred, pre-acclimated and specific pathogen free animals that meet our clients' rigorous quality control requirements. In 2007, Covance opened a dedicated animal biosafety level 2 (ABSL-2) containment vivarium to allow us to provide full service vaccine testing.

Bioanalytical Services. Our bioanalytical testing service, which is conducted in our bioanalytical laboratory in Indianapolis, Indiana and in our immunoanalytical facility in Chantilly, Virginia, as well as in our laboratories in Madison, Wisconsin and Harrogate, United Kingdom, helps determine the appropriate dose and frequency of drug application from late discovery evaluation through Phase III clinical testing on a full-scale, globally integrated basis.

Clinical Pharmacology Services

We provide clinical pharmacology services, including first-in-human trials, of new pharmaceuticals at our nine sites located throughout the United States and our one site in Leeds, United Kingdom, and also offer our clients access to specialized patient populations needed for Phase II trials in specific therapeutic areas. We have grown this service offering recently through acquisitions. In 2006, we significantly expanded our capacity and capabilities in the United States with the acquisition of Radiant's clinical pharmacology sites and its access to specialized patient populations, for cash payments totaling $66.6 million. In 2005, we acquired GFI for cash payments totaling $6.2 million.

Late-Stage Development

Central Laboratory Services

We are the world's largest provider of central laboratory services. We have four central laboratories, one in each of the United States, Switzerland, Singapore and China that provide central laboratory services, including biomarker services, to biotechnology and pharmaceutical customers. In 2007, we opened a new purpose built facility in Shanghai, China.

Our capabilities provide clients the flexibility to conduct studies on a multinational and simultaneous basis. The data we provide is combinable and results in global clinical trial reference ranges because we use consistent laboratory methods, identical reagents and calibrators, and similar equipment globally. Combinable data eliminates the cumbersome process of statistically correlating results generated using different methods and different laboratories on different equipment.

We also employ a proprietary clinical trials management system that enables us to enter a sponsor's protocol requirements directly into our database. The laboratory data can be audited because all laboratory data can be traced to source documents. In addition, the laboratories are capable of delivering customized data electronically within 24 hours of test completion. Covance also offers pharmacogenomic testing and sample storage technologies in conjunction with our central laboratory services. Central Laboratory Services also offers LabLink, an internet-based client access program that allows customers to review and query clinical trial lab data on a near real-time basis, and the Covance Local Laboratories service, which uses a proprietary system to harmonize laboratory results from local and regional laboratories to help expand the reach of traditional central laboratory services.

Our central laboratories have an automated kit production line that is located in the United States and supplies kits to investigator sites around the world. This system allows the flexibility to expand kit production volume more quickly and uses consistent methods to reduce supply variation for our customers.

Clinical Development Services

We offer a comprehensive range of clinical trial services, including the full management of Phase II and III clinical studies. We have extensive experience in a number of therapeutic areas, and we provide the following core services either on an individual or aggregated basis to meet clients' needs: study design and modeling; study orchestration; trial logistics; enablement of study site performance; clinical data management and biostatistical analysis; and medical writing and regulatory services.

We have extensive experience in managing clinical trials in North America, Europe, Latin America and Asia Pacific. These trials may be conducted separately or simultaneously as part of a multinational development plan. We can manage every aspect of clinical trials from clinical development plans and protocol design to New Drug Applications, among other supporting services. In 2006 and 2007, Clinical Development Services continued its expansion into Eastern Europe and Asia Pacific.

Our clinical development services utilize Trial Tracker®, a web-enabled clinical trial project management and tracking tool which allows both our employees and customers to review and manage all aspects of clinical trial projects. We have also integrated the management of clinical data across our Phase I through IV clinical services using the Oracle® clinical platform.

Clinical Trial Support Services

Cardiac Safety Services. In November 2007, we sold our centralized ECG business to eResearchTechnology Inc. for an upfront cash payment of approximately $35 million with the opportunity to receive up to an additional $14 million in contingent consideration relating to transferred backlog as well as from revenues generated from new contracts secured under a long-term marketing arrangement. We continue to offer this service to our clients through this marketing arrangement.

Interactive Voice and Web Response Services. To expedite the drug development process and to help reduce costs, we created a proprietary interactive trial management system. This system uses touch-tone telephone technology and, when requested, the internet for data entry purposes and assists our clients in managing clinical trials on a real-time basis and in reducing product waste with just-in-time inventory processing. This system, which is multi-lingual, is available world-wide through toll-free numbers 24 hours per day, seven days per week. We offer this system both in conjunction with clinical trials we conduct and as a stand-alone service.

Commercialization Services

Periapproval Services. Periapproval trials are studies conducted "around the time of NDA approval", generally after a drug has successfully undergone clinical efficacy and safety testing and the New Drug Application has been submitted to the Food and Drug Administration ("FDA"). We offer a range of periapproval services, including: Treatment Investigational New Drug applications; Phase IIIb clinical studies, which involve studies conducted after New Drug Application submission, but before regulatory approval is obtained; Phase IV clinical studies which are studies conducted after initial approval of the drug; and other types of periapproval studies such as post-marketing surveillance studies, FDA mandated post-marketing commitments generally focusing on characterizing a drug's safety in large, diverse patient groups, product withdrawal support services and prescription to over-the-counter switch studies.

Market Access Services. We offer a wide range of reimbursement and healthcare economics consulting services, including outcomes and pharmacoeconomic studies, reimbursement planning, reimbursement advocacy programs and registry services. Pharmaceutical, biotechnology and medical device

manufacturers purchase these services from us to help optimize their return on research and development investments. We offer InTeleCenter® services that employ state of the art phone, internet and electronic media to manage customer communications. InTeleCenter programs include reimbursement hotlines, patient assistance programs and patient compliance programs. We also field and process telephone calls and inquiries relating to adverse experiences with a drug while we perform the periapproval studies.

Customers and Marketing

We provide product development services on a global basis to, among others, the pharmaceutical and biotechnology industries. In 2007, we served in excess of 300 biopharmaceutical companies, ranging from the world's largest pharmaceutical companies and biotechnology companies to small and start-up organizations.

While no single customer accounted for more than ten percent of our aggregate net revenue in 2007, we had one customer accounting for more than five but less than ten percent of our net revenues, and our top five customers accounted for less than 25 percent of our net revenues. In our early development segment, no single customer accounted for more than ten percent of net revenues. Our early development segment had two customers accounting for more than five but less than ten percent of its aggregate net revenues. In our late-stage development segment, one customer accounted for more than ten percent of net revenues and two customers accounted for more than five but less than ten percent of its aggregate net revenues.

For net revenues from external customers, assets attributable to each of our business segments and other segment information for each of the last three fiscal years, please review Note 12 to the audited consolidated financial statements included elsewhere in this Annual Report.

For net revenues from external customers and long-lived assets attributable to operations in the United States, United Kingdom, Switzerland and other countries for each of the last three fiscal years, please review Note 12 to the audited consolidated financial statements included elsewhere in this Annual Report.

Our global sales activities are conducted by sales personnel based in our operations in the United States, Europe and Asia Pacific.

Contractual Arrangements

Many of our contracts with our clients are either fixed price or fee-for-service with a cap. To a lesser extent, some of our contracts are fee-for-service without a cap. In cases where the contracts are fixed price, we generally bear the cost of overruns, but we benefit if the costs are lower than we anticipated. In cases where our contracts are fee-for-service with a cap, the contracts contain an overall budget for the trial based on time and cost estimates. If our costs are lower than anticipated, the customer generally keeps the savings, but if our costs are higher than estimated, we are responsible for the overrun unless the increased cost is a result of a scope change or other factors outside of our control, such as an increase in the number of patients to be enrolled or the type or amount of data to be collected. Contracts may range in duration from a few months to several years or longer depending on the nature of the work performed. In some cases, a portion of the contract fee is paid at the time the study or trial is started with the balance of the contract fee payable in installments upon the achievement of milestones over the study or trial duration.

Most of our contracts may be terminated by the customer either immediately or upon notice. These contracts typically require payment to Covance of expenses to wind down a study, payment to Covance of fees earned to date, and, in some cases, a termination fee or payment to Covance of some portion of the fees or profit that could have been earned under the contract if it had not been terminated early.

Backlog

Some of our studies and projects are performed over an extended period of time, which may exceed several years. We maintain an order backlog to track anticipated net revenues yet to be earned for work that has

not yet been performed. However, we do not maintain an order backlog for other services that are performed within a short period of time or where it is not otherwise practical or feasible to maintain an order backlog. Our aggregate backlog at December 31, 2007 and December 31, 2006 was $2.68 billion and $2.23 billion respectively.

Backlog generally includes work to be performed under signed agreements (i.e., contracts and letters of intent). Once work under a signed agreement begins, net revenues are recognized over the life of the project. However, in some cases we will begin work on a project once we conclude we have a legally binding agreement, but before executing a signed agreement, and backlog may include the net revenues expected from that project.

We cannot provide any assurance that we will be able to realize all or most of the net revenues included in backlog or estimate the portion expected to be filled in the current year. Although backlog can provide meaningful information to our management with respect to a particular study, we believe that our aggregate backlog as of any date is not necessarily a meaningful indicator of our future results for a variety of reasons. These reasons include the following: studies vary in duration; the scope of studies may change, which may either increase or decrease their value; and studies may be terminated, reduced in scope or delayed at any time by the client or regulatory authorities.

Competition

The contract research organization industry has many participants ranging from hundreds of small, limited-service providers to a limited number of full-service contract research organizations with global capabilities. We primarily compete against in-house departments of pharmaceutical companies, full-service and limited-service contract research organizations and, to a lesser extent, selected universities and teaching hospitals.

In early development services, our significant competitors include Charles River Laboratories International Inc., MDS Inc., PPD, Inc., WIL Laboratories and MPI Research, among others. In late-stage development services our significant competitors include PPD, Inc., Quintiles Transnational Corp., Parexel International Corporation, Kendle International Inc., Icon PLC., PRA International, i3 Research, Pharmanet Development Group Inc. and Quest Diagnostics Incorporated, among others. Covance represents an important market presence in each segment's principal services.

There is competition for customers on the basis of many factors, including the following: reputation for on-time quality performance; expertise and experience in specific areas; scope of service offerings; strengths in various geographic markets; price; technological expertise and efficient drug development processes; ability to acquire, process, analyze and report data in a rapid and accurate manner; historic experience and relationship; ability to manage large-scale clinical trials both domestically and internationally; quality of facilities; expertise and experience in reimbursement and healthcare consulting; and size. We believe that we compete favorably in these areas.

Government Regulation

Our laboratory services are subject to various regulatory requirements designed to ensure the quality and integrity of the testing processes. Covance's standard operating procedures are written in accordance with regulations and guidelines appropriate to the region and the nation where they will be used.

The industry standards for conducting preclinical laboratory testing are embodied in the Good Laboratory Practice (GLP) and for central laboratory operations in the Clinical Laboratory Improvement Amendments of 1988 (CLIA). The standards of GLP are required by the FDA, by the Department of Health in the United Kingdom, by the European Agency for the Evaluation of Medicinal Products (EMEA) in Europe and by similar regulatory authorities in other parts of the world. To help satisfy its compliance obligations, Covance has established quality assurance controls at its laboratory facilities which monitor ongoing compliance with GLP and CLIA.

Our clinical services are subject to industry standards for the conduct of clinical research and development studies that are embodied in the regulations for Good Clinical Practice (GCP). The FDA, EMEA and other regulatory authorities require that test results submitted to such authorities be based on studies conducted in accordance with GCP. As with GLP and Good Manufacturing Practice (GMP), noncompliance with GCP can result in the disqualification of data collected during the clinical trial.

We strive to perform all clinical research in accordance with the International Conference on Harmonization—Good Clinical Practice Guidelines, and the requirements of the applicable country. Although the U.S. is a signatory to these guidelines, the FDA has not adopted all of these guidelines as statutory regulations, but has currently adopted them only as guidelines. From an international perspective, when applicable, we have implemented common standard operating procedures across regions to assure consistency whenever it is feasible and appropriate to do so.

Our animal import and breeding facilities and toxicology facilities are also subject to a variety of federal and state laws and regulations, including The Animal Welfare Act and the rules and regulations promulgated thereunder by the United States Department of Agriculture ("USDA") and corresponding rules and regulations in other jurisdictions. These facilities maintain detailed standard operating procedures and the documentation necessary to comply with applicable regulations for the humane treatment of the animals in their custody. Besides being licensed by the USDA as a dealer and/or research facility, as appropriate, these businesses are also accredited by the Association for Assessment and Accreditation of Laboratory Animal Care International and have registered assurance with the United States National Institutes of Health Office of Laboratory Animal Welfare.

The use of controlled substances in testing for drugs with a potential for abuse is regulated in the United States by the U.S. Drug Enforcement Administration and by similar regulatory bodies in other parts of the world. All Covance United States laboratories using controlled substances for testing purposes are licensed by the U.S. Drug Enforcement Administration.

Our United States laboratories are subject to licensing and regulation under federal, state and local laws relating to hazard communication and employee right-to-know regulations, the handling and disposal of medical specimens and hazardous waste and radioactive materials, as well as the safety and health of laboratory employees. All of our laboratories are subject to applicable federal and state laws and regulations relating to the storage and disposal of all laboratory specimens including the regulations of the Environmental Protection Agency, the Nuclear Regulatory Commission, the Department of Transportation, the National Fire Protection Agency and the Resource Conservation and Recovery Act. Although we believe that Covance is currently in compliance in all material respects with such federal, state and local laws, failure to comply could subject Covance to denial of the right to conduct business, fines, criminal penalties and other enforcement actions.

In addition to its comprehensive regulation of safety in the workplace, the Occupational Safety and Health Administration and similar regulatory authorities in foreign countries have established extensive requirements relating to workplace safety for health care employers, whose workers may be exposed to blood-borne pathogens such as HIV and the hepatitis B virus. Covance employees receive initial and periodic training focusing on compliance with applicable hazardous materials regulations and health and safety guidelines.

In the past few years, both the United States and foreign governments have become more concerned about the disclosure of confidential personal data. The European Union, or EU, now prohibits certain disclosures of personal confidential information, including medical information, to any entity that does not comply with certain security safeguards. We will continue to monitor our compliance with applicable regulations.

The regulations of the U.S. Department of Transportation, the U.S. Public Health Service and the U.S. Postal Service apply to the surface and air transportation of laboratory specimens. Covance's laboratories also must comply with the applicable International Air Transport Association regulations, which govern international shipments of laboratory specimens. Furthermore, when materials are sent to a foreign country, the transportation of such materials becomes subject to the laws, rules and regulations of such foreign country.

Intellectual Property

We have developed certain computer software and technically derived procedures and products intended to maximize the quality and effectiveness of our services. Although our intellectual property rights are important to our results of operations, we believe that such factors as the technical expertise, knowledge, ability and experience of our professionals are more important, and that, overall, these technological capabilities provide significant benefits to our clients.

Employees

At December 31, 2007, we had approximately 8,700 employees, approximately 35% of whom were employed outside of the United States and approximately 8,000 of whom were full time employees. Our records indicate that 134 of our employees hold M.D. degrees, 294 hold Ph.D. degrees, and 925 hold masters or other postgraduate degrees. We believe that Covance's relations with its employees are good.

Item 1A. Risk Factors

This section discusses various risk factors that are attendant with our business and the provision of our services. If the events outlined below were to occur individually or in the aggregate, our business, results of operations, financial condition and cash flows could be materially adversely affected.

Changes in government regulation or in practices relating to the pharmaceutical industry could decrease the need for the services we provide.

Governmental agencies throughout the world, including in the United States, strictly regulate the drug development process. Our business involves helping pharmaceutical and biotechnology companies navigate the regulatory drug approval process. Changes in regulation, such as a relaxation in regulatory requirements or the introduction of simplified drug approval procedures, or an increase in regulatory requirements that we have difficulty satisfying or that make our services less competitive, could eliminate or substantially reduce the demand for our services. Also, if government efforts to contain drug costs and pharmaceutical and biotechnology company profits from new drugs, our customers may spend less, or reduce their growth in spending on research and development. If health insurers were to change their practices with respect to reimbursements for pharmaceutical products, our customers may spend less, or reduce their growth in spending on research and development.

Failure to comply with existing regulations could result in a loss of revenue or earnings or in increased costs.

Any failure on our part to comply with applicable regulations could result in the termination of on-going research or the disqualification of data for submission to regulatory authorities. For example, if we were to fail to properly monitor compliance by clinical trial investigators with study protocols, the data collected from that trial could be disqualified. If this were to happen, we could be contractually required to repeat the trial at no further cost to our customer, but at substantial cost to us.

We may bear financial losses because most of our contracts are of a fixed price nature and may be delayed or terminated or reduced in scope for reasons beyond our control.

Many of our contracts provide for services on a fixed price or fee-for-service with a cap basis and they may be terminated or reduced in scope either immediately or upon notice. Cancellations may occur for a variety of reasons, including:

•: the failure of products to satisfy safety requirements;
•: unexpected or undesired results of the products;
•: insufficient patient enrollment;
•: insufficient investigator recruitment;
•: the client's decision to terminate the development of a product or to end a particular study; and
•: our failure to perform properly our duties under the contract.

The loss, reduction in scope or delay of a large contract or the loss or delay of multiple contracts could materially adversely affect our business, although our contracts frequently entitle us to receive the costs of winding down the terminated projects, as well as all fees earned by us up to the time of termination. Some contracts also entitle us to a termination fee.

We may bear financial risk if we under-price our contracts or overrun cost estimates.

Since our contracts are often structured as fixed price or fee-for-service with a cap, we bear the financial risk if we initially under-price our contracts or otherwise overrun our cost estimates. Such under-pricing or significant cost overruns could have a material adverse effect on our business, results of operations, financial condition, and cash flows.

We may not be able to successfully develop and market or acquire new services.

We may seek to develop and market new services that complement or expand our existing business or expand our service offerings through acquisition. If we are unable to develop new services and/or create demand for those newly developed services, or to expand our service offerings through acquisition, our future business, results of operations, financial condition, and cash flows could be adversely affected.

Our quarterly operating results may vary.

Our operating results may vary significantly from quarter to quarter and are influenced by factors over which we have little control such as:

•: exchange rate fluctuations;
•: the commencement, completion or cancellation of large contracts;
•: the progress of ongoing contracts;
•: the timing of and charges associated with completed acquisitions or other events; and
•: changes in the mix of our services.

We believe that operating results for any particular quarter are not necessarily a meaningful indication of future results. While fluctuations in our quarterly operating results could negatively or positively affect the market price of our common stock, these fluctuations may not be related to our future overall operating performance.

We depend on the pharmaceutical and biotechnology industries.

Our revenues depend greatly on the expenditures made by the pharmaceutical and biotechnology industries in research and development. Accordingly, economic factors and industry trends that affect our clients in these industries also affect our business. If companies in these industries were to reduce the number of research and development projects they outsource, our business could be materially adversely affected.

We operate in a highly competitive industry.

Competitors in the contract research organization industry range from small, limited-service providers to full service global contract research organizations. Our main competition consists of in-house departments of pharmaceutical companies, full-service and functional contract research organizations, as well as universities and teaching hospitals, to a lesser degree. We compete on a variety of factors, including:

•: reputation for on-time quality performance and regulatory compliance;
•: expertise and experience in specific areas;
•: scope of service offerings;
•: strengths in various geographic markets;
•: price;
•: technological expertise and efficient drug development processes;
•: quality of facilities;
•: ability to acquire, process, analyze and report data in an accurate manner;
•: ability to manage large-scale clinical trials both domestically and internationally;
•: expertise and experience in market access services; and
•: size.

For instance, our clinical development services have from time-to-time experienced periods of increased price competition which had a material adverse effect on Covance's late-stage development profitability and consolidated net revenues and net income.

There is competition among the larger contract research organizations for both clients and potential acquisition candidates. Additionally, small, limited-service entities considering entering the contract research organization industry will find few barriers to entry, thus further increasing possible competition. These competitive pressures may affect the attractiveness of our services and could adversely affect our financial results.

We may expand our business through acquisitions.

We review many acquisition candidates and, in addition to acquisitions which we have already made, we are continually evaluating new acquisition opportunities. Factors which may affect our ability to grow successfully through acquisitions include:

•: difficulties and expenses in connection with integrating the acquired companies and achieving the expected benefits;
•: diversion of management's attention from current operations;
•: the possibility that we may be adversely affected by risk factors facing the acquired companies;
•: acquisitions could be dilutive to earnings, or in the event of acquisitions made through the issuance of our common stock to the shareholders of the acquired company, dilutive to the percentage of ownership of our existing stockholders;
•: potential losses resulting from undiscovered liabilities of acquired companies not covered by the indemnification we may obtain from the seller;
•: risks of not being able to overcome differences in foreign business practices, language and other cultural barriers in connection with the acquisition of foreign companies; and
•: loss of key employees of the acquired companies.

We may be affected by potential healthcare reform.

In recent years the United States Congress and state legislatures have considered various types of healthcare reform in order to control growing health care costs. We are unable to predict what legislative proposals will be adopted in the future, if any. Similar reform movements have occurred in Europe and Asia.

Implementation of healthcare reform legislation that contain costs could limit the profits that can be made from the development of new drugs. This could adversely affect research and development expenditures by pharmaceutical and biotechnology companies which could in turn decrease the business opportunities available to us both in the United States and abroad. In addition, new laws or regulations may create a risk of liability, increase our costs or limit our service offerings.

We rely on third parties for important services.

We depend on third parties to provide us with services critical to our business. The failure of any of these third parties to adequately provide the needed services could have a material adverse effect on our business.

Our revenues and earnings are exposed to exchange rate fluctuations.

We derive a large portion of our net revenues from international operations. For the year ended December 31, 2007, we derived approximately 38% of our net revenues from outside the United States. Our financial statements are denominated in U.S. dollars. In addition, in certain circumstances, we may incur costs in one currency related to our services or products for which we are paid in a different currency. As a result, factors associated with international operations, including changes in foreign currency exchange rates, could significantly affect our results of operations, financial condition and cash flows.

The loss of our key personnel could adversely affect our business.

Our success depends to a significant extent upon the efforts of our senior management team and other key personnel. The loss of the services of such personnel could adversely affect our business. Also, because of the nature of our business, our success is dependent upon our ability to attract and retain technologically qualified personnel. There is substantial competition for qualified personnel, and an inability to recruit or retain qualified personnel may impact our ability to grow our business and compete effectively in our industry.

Contract research services create a risk of liability.

In contracting to work on drug development trials and studies, we face a range of potential liabilities, for example:

•: errors or omissions that create harm during a trial to study volunteers or after a trial to consumers of the drug after regulatory approval of the drug;
•: general risks associated with clinical pharmacology facilities, including negative consequences from the administration of drugs to clinical trial participants or the professional malpractice of clinical pharmacology medical care providers;
•: errors or omissions from tests conducted for the chemical, agrochemical and food industries;
•: risks that animals in our breeding facilities may be infected with diseases that may be harmful and even lethal to themselves and humans despite preventive measures contained in our company policies for the quarantine and handling of imported animals; and
•: errors and omissions during a trial or study that may undermine the usefulness of a trial or data from the trial or study.

We also contract with physicians, also referred to as investigators, to conduct the clinical trials to test new drugs on human volunteers. These tests can create a risk of liability for personal injury or death to volunteers, resulting from negative reactions to the drugs administered or from professional malpractice by third party investigators. We believe that our risks in this area are generally reduced by the following:

•: contract provisions entitling us to be indemnified or entitling us to a limitation of liability;
•: insurance maintained by our clients, investigators, and by us; and
•: our efforts to comply with various regulatory requirements we must follow in connection with our business.

Contractual indemnifications generally do not protect us against liability arising from certain of our own actions, such as negligence or misconduct. We could be materially and adversely affected if we were required to pay damages or bear the costs of defending any claim which is not covered by a contractual indemnification provision or in the event that a party who must indemnify us does not fulfill its indemnification obligations or which is beyond the level of our insurance coverage. There can be no assurance that insurance will cover all of such losses or that we will be able to maintain such insurance coverage on terms acceptable to us.

Hardware and software failures, delays in the operation of our computer and communications systems or the failure to implement system enhancements may harm our business.

Our success depends on the efficient and uninterrupted operation of our computer and communications systems. A failure of our network or data gathering procedures could impede the processing of data, delivery of databases and services, client orders and day-to-day management of our business and could result in the corruption or loss of data. While certain of our operations have appropriate disaster recovery plans in place, we currently do not have redundant facilities everywhere in the world to provide IT capacity in the event of a system failure. Despite any precautions we may take, damage from fire, floods, hurricanes, power loss, telecommunications failures, computer viruses, break-ins and similar events at our various computer facilities could result in interruptions in the flow of data to our servers and from our servers to our clients. In addition, any failure by our computer environment to provide our required data communications capacity could result in interruptions in our service. In the event of a delay in the delivery of data, we could be required to transfer our data collection operations to an alternative provider of server hosting services. Such a transfer could result in delays in our ability to deliver our products and services to our clients. Additionally, significant delays in the planned delivery of system enhancements, improvements and inadequate performance of the systems once they are completed could damage our reputation and harm our business. Finally, long-term disruptions in the infrastructure caused by events such as natural disasters, the outbreak of war, the escalation of hostilities, and acts of terrorism (particularly involving cities in which we have offices) could adversely affect our businesses. Although we carry property and business interruption insurance, our coverage may not be adequate to compensate us for all losses that may occur.

Reliance on Facilities

Covance relies on certain of its facilities. In particular, Covance's preclinical and central laboratory facilities are highly specific and would be difficult to replace in a short period of time. Any event that causes a disruption of the operation of these facilities might impact the Company's ability to provide service to its customers and therefore could have a material adverse affect on its financial condition, results of operations and cash flows.

Reliance on air transportation.

Our central laboratories and certain of our other businesses are heavily reliant on air travel for transport of clinical trial kits and other material, products and people, and a significant disruption to the air travel system, or our access to it, could have a material adverse effect on our business.

Certain service offerings and research products are dependent on limited sources of supply of services or products which if interrupted could affect our business.

We depend on a limited number of suppliers for certain services and for certain animal populations. Disruptions to the continued supply of these services or products may arise from export import restrictions or embargoes, foreign political or economic instability, or otherwise. Disruption of supply could have a material adverse effect on our business.

Actions of animal rights extremists may affect our business.

Our early development services utilize animals in preclinical testing of the safety and efficacy of drugs and also breed and sell animals for biomedical research. Such activities are required for the development of new medicines and medical devices under regulatory regimes in the United States, Europe, Japan and other countries. Acts of vandalism and other acts by animal rights extremists who object to the use of animals in drug development could have a material adverse effect on our business.

Our animal populations may suffer diseases that can damage our inventory, harm our reputation, result in decreased sales of research products or result in other liability to us.

It is important that our research products be free of diseases, including infectious diseases. The presence of diseases can distort or compromise the quality of research results, can cause loss of animals in our inventory, can result in harm to humans or outside animal populations if the disease is not contained to animals in inventory, or can result in other losses. Such results could harm our reputation or have a material adverse effect on our financial condition, results of operations, and cash flows.

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

Overview

Covance is a leading drug development services company providing a wide range of early-stage and late-stage product development services on a worldwide basis primarily to the pharmaceutical, biotechnology and medical device industries. Covance also provides services such as laboratory testing to the chemical, agrochemical and food industries. The foregoing services comprise two reportable segments for financial reporting purposes: early development services, which includes preclinical and clinical pharmacology service offerings; and late-stage development services, which includes central laboratory, clinical development, periapproval and market access services. Although each segment has separate services within it, they can be combined in joint service offerings and we believe clients increasingly are interested in opportunities for such combined services. Covance believes it is one of the largest drug development services companies, based on annual net revenues, and one of a few that is capable of providing comprehensive global product development services. Covance offers its clients high quality services designed to provide data to clients as rapidly as possible and reduce product development time. We believe this enables Covance's customers to introduce their products into the marketplace faster and as a result, maximize the period of market exclusivity and monetary return on their research and development investments. Additionally, Covance's comprehensive services and broad experience provide its customers with a variable cost alternative to fixed cost internal development capabilities.

Critical Accounting Policies

Covance's consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles ("GAAP"), which require management to make estimates and assumptions about future events that affect the amounts reported in the financial statements and the accompanying notes. Actual results could differ from these estimates. The following discussion highlights what we believe to be the critical accounting policies and judgments made in the preparation of these consolidated financial statements.

Revenue Recognition. Covance recognizes revenue either as services are performed or products are delivered, depending upon the nature of the work contracted. Historically, a majority of Covance's net revenues have been earned under contracts which range in duration from a few months to two years, but can extend in duration up to five years or longer. Service contracts generally take the form of fee-for-service or fixed-price arrangements. In the case of fee-for-service contracts, revenue is recognized as services are performed, based upon, for example, hours worked or samples tested. For long-term fixed-price service contracts, revenue is recognized as services are performed, with performance generally assessed using output measures, such as units-of-work performed to date as compared to the total units-of-work contracted. Changes in the scope of work generally result in a renegotiation of contract pricing terms. Renegotiated amounts are not included in net revenues until earned and realization is assured. Estimates of costs to complete are made to provide, where appropriate, for losses expected on contracts. Costs are not deferred in anticipation of contracts being awarded, but instead are expensed as incurred. In some cases, a portion of the contract fee is paid at the time the trial is initiated. These advances are deferred and recognized as revenue as services are performed or products are delivered, as discussed above. Additional payments may be made based upon the achievement of performance-based milestones over the contract duration. Most contracts are terminable by the client either immediately or upon notice. These contracts typically require payment to Covance of expenses to wind down the study, fees earned to date and, in some cases, a termination fee or a payment to Covance of some portion of the fees or profits that could have been earned by Covance under the contract if it had not been terminated early. Termination fees are included in net revenues when realization is assured.

Bad Debts. Covance endeavors to assess and monitor the creditworthiness of its customers to which it grants credit terms in the ordinary course of business. Covance maintains a provision for doubtful accounts relating to amounts due that may not be collected. This bad debt provision is monitored on a monthly basis and adjusted as circumstances warrant. Since the recorded bad debt provision is based upon management's judgment, actual bad debt write-offs may be greater or less than the amount recorded. Historically, bad debt write-offs have not been material.

Taxes. Since Covance conducts operations on a global basis, its effective tax rate has and will continue to depend upon the geographic distribution of its pre-tax earnings among locations with varying tax rates. Covance's profits are further impacted by changes in the tax rates of the various jurisdictions in which Covance operates. In addition, Covance maintains a tax reserve for unrecognized tax benefits, changes to which could impact Covance's effective tax rate in the period such changes are made.

Effective January 1, 2007, the Company adopted the provisions of Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes—an Interpretation of FASB Statement No. 109 ("FIN 48"). This authoritative interpretation expanded upon and standardized the manner by which companies are required to account for unrecognized tax benefits. Under the guidance of FIN 48, the Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not to be sustained upon examination based on the technical merits of the position. The amount of the accrual for which an exposure exists is measured as the largest amount of benefit determined on a cumulative probability basis that the Company believes is more likely than not to be realized upon ultimate settlement of the position. On January 1, 2007, the Company recognized a $0.6 million increase to its liability for unrecognized tax benefits, which was accounted for as a reduction to retained earnings, for the cumulative effect change of adopting FIN 48. The reserve for unrecognized tax benefits at January 1, 2007, as calculated under the measurement provisions of FIN 48, was $9.1 million. Components of the reserve are classified as either a current or long-term liability in the Consolidated Balance Sheet, based on when the Company expects each of the items to be settled. Accordingly, the Company recorded a current liability of $3.5 million in accrued expenses and other current liabilities and a long-term liability of $5.6 million in other liabilities on its Consolidated Balance Sheet at January 1, 2007, including accrued interest of $1.3 million. Consistent with historical practice, Covance records interest and penalties accrued in relation to unrecognized tax benefits as a component of income tax expense.

As of December 31, 2007, the balance of the reserve for unrecognized tax benefits was $8.9 million, of which $2.6 million is recorded as a current liability in accrued expenses and other current liabilities, and $6.3 million is recorded as a long-term liability in other liabilities on the Consolidated Balance Sheet, including accrued interest of $1.3 million. This reserve relates to exposures for income tax matters such as transfer pricing, nexus, deemed dividends and research and development credits. The net reduction in the reserve for unrecognized tax benefits from January 1 to December 31, 2007 resulted from the settlement of various state and foreign audits and the recognition of previously unrecognized tax benefits in jurisdictions where the statute of limitations had lapsed, offset by the accrual of additional reserves in 2007, primarily relating to transfer pricing and research and development credit utilization.

Following is a reconciliation of the beginning and ending amount of unrecognized tax benefits, excluding accrued interest of $1.3 million:

(dollars in millions)

Unrecognized tax benefits as of January 1, 2007, at date of adoption	$	7.8
Additions related to tax positions in the prior year		1.1
Additions related to tax positions in the current year		1.3
Reductions due to settlements and payments		(0.8	)
Reductions due to statute expiration		(1.8	)

Unrecognized tax benefits as of December 31, 2007	$	7.6

Any future changes in the $8.9 million liability for unrecognized tax benefits, resulting from the recognition of tax benefits, would impact the effective tax rate of Covance. Over the next twelve months, it is reasonably possible that the uncertainty surrounding a portion of the reserve for unrecognized tax benefits, related to certain income taxes, dividend income, transfer pricing and state tax issues, will be resolved as a result of the expiration of the statute of limitations or the conclusion of various federal, state and foreign tax audits. As a result, Covance would reduce the carrying value of its reserve for these items by up to $1.9 million including interest of $0.5 million.

The following tax years remain open to investigation as of December 31, 2007, for the Company's major jurisdictions:

Tax Jurisdiction		Years

US Federal and State			2002-2007
United Kingdom			2005-2007
Switzerland			2003-2007
Germany			2007

The Company also maintains a tax reserve related to exposures for non-income tax matters including value-added tax and state sales and use and other taxes, which are accounted for in accordance with Statement of Financial Accounting Standards No. 5, Accounting for Contingencies. The balance of this reserve at December 31, 2007 is $0.8 million and is recorded as a current liability in accrued expenses and other current liabilities on the Consolidated Balance Sheet. This reserve was reduced by $0.3 million from the January 1, 2007 balance of $1.1 million, primarily from the settlement of state and foreign audits, partially offset by the accrual of interest on outstanding reserves in 2007.

While Covance believes it has identified all reasonably identifiable exposures and the reserve it has established for identifiable exposures is appropriate under the circumstances, it is possible that additional exposures exist and that exposures will be settled at amounts different than the amounts reserved. It is also possible that changes in facts and circumstances could cause Covance to either materially increase or reduce the carrying amount of its tax reserves.

Covance's policy is to provide income taxes on earnings of foreign subsidiaries only to the extent those earnings are taxable or are expected to be remitted. Covance's historical policy has been to leave its unremitted foreign earnings invested indefinitely outside the United States. Except for the amounts repatriated in the fourth quarter of 2005 under the American Jobs Creation Act of 2004 (the "Act"), Covance intends to continue to leave its unremitted foreign earnings invested indefinitely outside the United States. As a result, taxes have not been provided on any of the remaining accumulated foreign unremitted earnings totaling approximately $267 million at December 31, 2007.

Stock-Based Compensation. The Company sponsors several stock-based compensation plans pursuant to which non-qualified stock options and restricted stock awards are granted to eligible employees.

Effective January 1, 2006, the Company adopted the fair value recognition provisions of Statement of Financial Accounting Standards No. 123R, Share-Based Payments, ("SFAS 123R") using the modified prospective transition method. SFAS 123R revised SFAS 123, superseded APB 25 and amended Statement of Financial Accounting Standards No. 95, Statement of Cash Flows. Under that transition method, compensation expense is now recognized in the financial statements on a go forward basis for (a) all share-based payments granted prior to, but not vested as of January 1, 2006, based upon the grant-date fair value estimated in accordance with the original provisions of SFAS 123, and (b) share-based payments granted on or subsequent to January 1, 2006, based upon the grant-date fair value estimated in accordance with the provisions of SFAS 123R. The grant-date fair value of awards expected to vest is expensed on a straight-line basis over the vesting period of the related awards. Under the modified prospective transition method, results for prior periods have not been restated.

an exercise price equal to the market value of the underlying common stock on the date of grant. Additionally, no compensation expense was recorded in the financial statements for shares purchased by employees under the Company's Employee Stock Purchase Plan (pursuant to which employees are able to purchase shares of the Company's common stock at a price equal to 85% of the lower of the market value on the first or last day of each calendar quarter) as that plan was considered to be non-compensatory under APB 25.

Prior to the adoption of SFAS 123R, the Company used stock options as the vehicle through which stock-based compensation awards were granted to eligible employees, other than executive officers who historically were granted a combination of performance-based share awards and stock options. As a result of the adoption of SFAS 123R, the Company is now using a mix of restricted share awards and stock options as the vehicles through which stock-based compensation awards are granted to eligible employees, other than executive officers who continue to receive a combination of performance-based share awards and stock options.

The grant-date fair value of stock awards is based upon the underlying price of the stock on the date of grant. The grant-date fair value of stock option awards must be determined using an option pricing model. Option pricing models require the use of estimates and assumptions as to (a) the expected term of the option, (b) the expected volatility of the price of the underlying stock, (c) the risk-free interest rate for the expected term of the option and (d) pre-vesting forfeiture rates. For stock options granted prior to January 1, 2006, the Company used the Black-Scholes-Merton option pricing formula for determining the grant-date fair value of such awards. For stock options granted on or subsequent to January 1, 2006, the Company is using the Lattice-Binomial option pricing formula for determining the grant-date fair value of stock option awards. The Company changed to the Lattice-Binomial option pricing formula as it believes such formula may result in a better estimate of fair value than the Black-Scholes-Merton formula.

The expected term of the option is based upon the contractual term and expected employee exercise and expected post-vesting employment termination behavior. The expected volatility of the price of the underlying stock is based upon the historical volatility of the Company's stock computed over a period of time equal to the expected term of the option. The risk free interest rate is based upon the implied yields currently available from the U.S. Treasury zero-coupon yield curve for issues with a remaining duration equal to the expected term of the option. Pre-vesting forfeiture rates are estimated based upon past voluntary termination behavior and past option forfeitures.

The following table sets forth the weighted-average assumptions used to calculate the fair value of options granted for the years ended December 31, 2007, 2006 and 2005:




Expected stock price volatility	42%	44%	44%
Risk free interest rate(s)	4.7% - 5.1%	3.9% - 4.5%	3.7%
Expected life of options (years)	4.3	4.3	5.0

Changes in any of these assumptions could impact, potentially materially, the amount of expense recorded in future periods related to stock-based awards.

As of December 31, 2007, the total unrecognized compensation cost related to non-vested stock options granted was $5.7 million and is expected to be recognized over a weighted average period of 1.4 years. As of December 31, 2007, the total unrecognized compensation cost related to non-vested performance-based shares and restricted stock awards was $19.9 million and is expected to be recognized over a weighted average period of 1.8 years.

Impairment of Assets. Covance reviews its long-lived assets other than goodwill and other indefinite lived intangible assets for impairment, when events or changes in circumstances occur that indicate the carrying value of the asset may not be recoverable. The assessment of possible impairment is based upon Covance's judgment of its ability to recover the asset from the expected future undiscounted cash flows of the related operations. Actual future cash flows may be greater or less than estimated.

Covance performs an annual test for impairment of goodwill and other indefinite lived intangible assets during the fourth quarter. This test is performed by comparing, at the reporting unit level, the carrying value of the reporting unit to its fair value. Covance assesses fair value based upon its estimate of the present value of the future cash flows that it expects to be generated by the reporting unit. The test performed for 2007 did not identify any instances of impairment. However, changes in expectations as to the present value of a reporting unit's future cash flows might impact subsequent years' assessments of impairment.

Defined Benefit Pension Plans. Covance sponsors defined benefit pension plans for the benefit of its employees at three foreign subsidiaries as well as a non-qualified supplemental executive retirement plan and a post-employment retiree health and welfare plan for the benefit of eligible employees at certain U.S. subsidiaries. The measurement of the related benefit obligation and net periodic benefit cost recorded each year is based upon actuarial computations which require the use of judgment as to certain assumptions. The more significant of these assumptions are: (a) the appropriate discount rate to use in computing the present value of the benefit obligation; (b) the expected return on plan assets (for funded plans); and (c) the expected future rate of salary increases (for pay-related plans). Actual results (such as the return on plan assets, future rate of salary increases and plan participation rates) will likely differ from the assumptions used. Those differences, along with changes that may be made in the assumptions used from period to period, will impact the amounts reported in the financial statements and footnote disclosures.

Set forth below is a discussion of the impact that (a) differences between assumed results and actual results and (b) assumption changes have had on our results of operations for the years ended December 31, 2007, 2006 and 2005 and on the financial position of the plans as of December 31, 2007 and 2006 for our United Kingdom defined benefit pension plans (the largest of our defined benefit-type pension plans).

Foreign Currency Risks

Since Covance operates on a global basis, it is exposed to various foreign currency risks. Two specific risks arise from the nature of certain contracts. The first risk can occur when Covance executes contracts with its customers where the contracts are denominated in a currency different than the local currencies of the Covance subsidiaries performing work under the contracts. As a result, revenue recognized for services rendered may be denominated in a currency different from the currencies in which the subsidiaries' expenses are incurred. Fluctuations in exchange rates (from those in effect at the time the contract is executed and pricing is established to the time services are rendered and revenue is recognized) can affect the subsidiary's net revenues and resultant earnings. This risk is generally applicable only to a portion of the contracts executed by Covance's subsidiaries providing clinical services. Historically, fluctuations in exchange rates from those in effect at the time contracts were executed have not had a material effect upon Covance's consolidated financial results. See "Risk Factors".

We also have other cross-currency contracts executed by other Covance subsidiaries where the foreign currency amounts billed are determined by converting local currency revenue amounts to the contract billing currency using the exchange rates in effect at the time services are rendered. These contracts do not give rise to foreign currency denominated revenue and local currency denominated expenses, but they do give rise to a second type of risk. This second type of risk results from the passage of time between the invoicing of customers under both of these types of contracts and the ultimate collection of customer payments against such invoices. Because such invoices are denominated in a currency other than the subsidiary's local currency, Covance recognizes a receivable at the time of invoicing for the local currency equivalent of the foreign currency invoice amount as of the invoice date. Subsequent changes in exchange rates from the time the invoice is prepared to the time payment from the customer is received will result in Covance receiving either more or less in local currency than the local currency equivalent of the invoice amount at the time the invoice was prepared and the receivable was recorded. This difference is recognized by Covance as a foreign currency transaction gain or loss, as applicable, in the Consolidated Statements of Income.

Finally, Covance's consolidated financial statements are denominated in U.S. dollars. Accordingly, changes in exchange rates between the applicable foreign currency and the U.S. dollar will affect the translation of each foreign subsidiary's financial results into U.S. dollars for purposes of reporting Covance's consolidated financial results. The process by which each foreign subsidiary's financial results are translated into U.S. dollars is as follows: income statement accounts are translated at average exchange rates for the period; balance sheet

asset and liability accounts are translated at end of period exchange rates; and equity accounts are translated at historical exchange rates. Translation of the balance sheet in this manner affects the stockholders' equity account, referred to as the cumulative translation adjustment account. This account exists only in the foreign subsidiary's U.S. dollar balance sheet and is necessary to keep the foreign balance sheet stated in U.S. dollars in balance. At December 31, 2007, accumulated other comprehensive income on the consolidated balance sheet includes the cumulative translation account balance of $45.3 million.

Operating Expenses and Reimbursable Out-of-Pockets

Covance segregates its recurring operating expenses among four categories: cost of revenue; reimbursed out-of-pocket expenses; selling, general and administrative expenses; and depreciation and amortization. Cost of revenue includes direct labor and related benefits, other direct costs, shipping and handling fees, and an allocation of facility charges and information technology costs, and excludes depreciation and amortization. Cost of revenue, as a percentage of net revenues, tends and is expected to fluctuate from one period to another, as a result of changes in labor utilization and the mix of service offerings involving hundreds of studies conducted during any period of time. Selling, general and administrative expenses consist primarily of administrative payroll and related benefit charges, advertising and promotional expenses, administrative travel and an allocation of facility charges and information technology costs, and excludes depreciation and amortization.

In connection with the management of multi-site clinical trials, Covance pays on behalf of its customers fees to investigators, volunteers and other out-of-pocket costs (such as for travel, printing, meetings, couriers, etc.), for which it is reimbursed at cost, without mark-up or profit. Investigator fees are not reflected in total revenues or expenses where Covance acts in the capacity of an agent on behalf of the pharmaceutical company sponsor, passing through these costs without risk or reward to Covance. All other out-of-pocket costs are included in total revenues and expenses.

Results of Operations

Year Ended December 31, 2007 Compared with Year Ended December 31, 2006. Net revenues increased 15.4%, or 12.8% excluding the impact of foreign exchange rate variances between both periods, to $1.55 billion for 2007 from $1.34 billion for 2006. Net revenues from Covance's early development segment grew 22.9%, or 20.0% excluding the impact of foreign exchange rate variances between both periods, on strong broad-based performance across the segment's service offerings. Net revenues from Covance's late-stage development segment grew 8.7%, or 6.3% excluding the impact of foreign exchange rate variances between both periods. Strength in clinical development more than offset softness in (1) central laboratory services during the first half of 2007, caused by delays in enrollment, longer trial durations and a shift in the geographic and therapeutic mix of studies; (2) cardiac safety services, due to low orders; and (3) commercialization services, due primarily to fewer new biological service launches.

Cost of revenue increased 15.4% to $1.02 billion or 65.8% of net revenues for the year ended December 31, 2007 as compared to $882.2 million or 65.8% of net revenues for the corresponding 2006 period.

Overall, selling, general and administrative expenses increased 12.8% to $233.9 million for 2007 from $207.4 million for 2006. As a percentage of net revenues, selling, general and administrative expenses decreased 40 basis points to 15.1% in 2007 from 15.5% in 2006.

Depreciation and amortization increased 15.3% to $66.2 million or 4.3% of net revenues for 2007 from $57.4 million or 4.3% of net revenues for 2006 primarily as a result of higher levels of capital spending during 2007.

Income from operations increased 18.3% to $228.6 million or 14.8% of net revenues for 2007 from $193.2 million or 14.4% of net revenues for the corresponding 2006 period. Income from operations from

Covance's early development segment increased $42.3 million or 27.6% to $195.9 million or 25.2% of net revenues for the year ended December 31, 2007 from $153.6 million or 24.3% of net revenues for the corresponding 2006 period. The $42.3 million increase over the prior year was driven primarily by strength in our global toxicology, chemistry and clinical pharmacology services. Income from operations from Covance's late-stage development segment increased $4.5 million or 3.6% to $128.1 million or 16.7% of net revenues for 2007 from $123.7 million or 17.5% of net revenues for the corresponding 2006 period. While clinical development services operating margin expanded over the prior year, revenue softness in central laboratory in the first half of 2007, cardiac safety and commercialization services, resulted in a decline in Late-Stage Development operating margin as a percentage of revenue as compared to the prior year. Corporate expense increased $11.4 million to $95.4 million or 6.2% of net revenues for 2007 from $84.0 million or 6.3% of net revenues for 2006. Included in Corporate expense is stock-based compensation expense of $21.9 million or 1.4% of net revenues for 2007, as compared to $21.5 million or 1.6% of net revenues for the corresponding 2006 period. The increase in Corporate expenses also reflects an increase in compensation-related expenses and investments in infrastructure to support higher levels of current and expected future growth.

Other income, net increased $10.4 million to $17.8 million for 2007 from $7.4 million for 2006 primarily as a result of the $6.6 million gain on sale of Covance's cardiac safety service offering and a $2.5 million increase in interest income resulting from higher invested cash balances and higher average interest rates earned on those balances in 2007.

Covance's effective tax rate for the year ended December 31, 2007 was 29.6% compared to 28.5% for the corresponding 2006 period. The effective tax rate for 2006 included the impact of a $2.5 million reduction in income tax reserves resulting from favorable income tax developments arising in the third quarter, which reduced the effective tax rate in 2006 by 120 basis points.

Covance has a 47% minority equity position in Noveprim Limited, a supplier of research products. During the years ended December 31, 2007 and 2006, Covance recognized $2.0 million and $1.6 million, respectively, representing its share of Noveprim's earnings, less an elimination of profit on inventory purchased from Noveprim Limited and still on hand at Covance at December 31, 2007 and 2006.

Net income of $175.9 million for the year ended December 31, 2007 increased $30.9 million or 21.3% as compared to $145.0 million for the corresponding 2006 period, and includes the $4.1 million after tax gain on the sale of Covance's cardiac safety service offering.

Items Affecting Comparability Between 2006 and 2005

Prior to 2006, the Company followed the disclosure-only provisions of SFAS 123, and, accordingly, accounted for awards under its stock-based compensation plans pursuant to the recognition and measurement principles of APB 25 and related Interpretations, as permitted by SFAS 123. Under APB 25, compensation expense was recognized in the financial statements relating to awards of stock. However, no compensation expense was recorded in the financial statements for stock option grants, as all options have been granted with an exercise price equal to the market value of the underlying common stock on the date of grant. Additionally, no compensation expense was recorded in the financial statements for shares purchased by employees under the Company's Employee Stock Purchase Plan (pursuant to which employees are able to purchase shares of the Company's common stock at a price equal to 85% of the lower of the market value on the first or last day of each calendar quarter) as that plan was considered to be non-compensatory under APB 25. Covance reflected the expense associated with the fair value of stock-based awards in its required pro forma footnote disclosure under SFAS 123 in its SEC filings.

Effective January 1, 2006, the Company adopted the fair value recognition provisions of SFAS 123R using the modified prospective transition method. SFAS 123R revises SFAS 123, supersedes APB 25 and amends Statement of Financial Accounting Standards No. 95, Statement of Cash Flows. Under that transition method, compensation expense is now recognized in the financial statements on a prospective basis for (a) all share-based payments granted prior to, but not vested as of January 1, 2006, based upon the grant-date fair value estimated in accordance with the original provisions of SFAS 123, and (b) share-based payments granted on or subsequent to January 1, 2006, based upon the grant-date fair value estimated in accordance with the provisions of SFAS 123R. The grant-date fair value of awards expected to vest is expensed on a straight-line basis over the vesting period of the related awards. Under the modified prospective transition method, results for prior periods have not been restated.

Management believes that it may be useful for investors, in evaluating 2006 financial performance, to compare to 2005 results that include stock-based compensation computed in accordance with SFAS 123. Management does not assert that such pro forma numbers are superior to the 2005 "as reported" results; however, the pro forma numbers may help investors compare results including stock option expense across both periods.

Although the Company is now using the Lattice-Binomial option pricing formula for valuing stock options granted beginning in 2006 (whereas previously the Company had used the Black-Scholes-Merton option pricing formula), management believes that the Lattice-Binomial and the Black-Scholes-Merton option pricing formulas, with the assumptions used by the Company, result in fair values which are substantially similar in all material respects. As a result, the Company believes that the 2006 "as reported" amounts under SFAS 123R are comparable to the 2005 "pro forma" amounts as previously disclosed under SFAS 123.

Year Ended December 31, 2006 Compared with Year Ended December 31, 2005. Net revenues increased 12.3% to $1.34 billion for 2006 from $1.19 billion for 2005. Net revenues from Covance's early development segment grew 12.6% on strong performance in our global toxicology, chemistry and clinical pharmacology services. Net revenues from Covance's late-stage development segment grew 12.2%, driven by strong performance in our central laboratory services.

Cost of revenue increased 11.4% to $882.2 million or 65.8% of net revenues for the year ended December 31, 2006 as compared to $791.7 million or 66.4% of net revenues for the corresponding 2005 period. Comparisons to the prior year are impacted by the inclusion of $7.0 million in stock-based compensation in cost of revenue in the 2006 period pursuant to SFAS 123R. These expenses reduced 2006 gross margins by approximately 50 basis points to 34.2% of net revenues. Had stock-based compensation been included in cost of revenue for the year ended December 31, 2005 under SFAS 123, cost of revenue would have been $7.8 million higher and gross margins (excluding depreciation and amortization) would have been approximately 60 basis points lower or 33.0% of net revenue on a pro forma basis.

Overall, selling, general and administrative expenses increased 16.3% to $207.4 million for 2006 from $178.4 million for 2005. As a percentage of net revenues, selling, general and administrative expenses increased 50 basis points to 15.5% for 2006 from 15.0% for 2005. Comparisons to the prior year are impacted by the inclusion of $8.5 million in stock-based compensation in selling, general and administrative expenses in the 2006 period pursuant to SFAS 123R. These expenses increased selling, general and administrative expenses as a percentage of revenue by approximately 70 basis points. Had incremental stock-based compensation been included in selling, general and administrative expenses for the year ended December 31, 2005 under SFAS 123, selling, general and administrative expenses would have been $9.6 million higher and selling, general and administrative expenses as a percentage of revenue would have been approximately 80 basis points higher or 15.8% of net revenue on a pro forma basis.

Depreciation and amortization increased 20.0% to $57.4 million or 4.3% of net revenues for 2006 from $47.8 million or 4.0% of net revenues for 2005 primarily as a result of higher levels of capital spending over the last fifteen months.

Income from operations increased 10.4% to $193.2 million or 14.4% of net revenues for 2006 from $175.1 million or 14.7% of net revenues for the corresponding 2005 period. Comparisons to the prior year are impacted by the inclusion of $15.5 million in stock-based compensation in operating expenses in the 2006 period pursuant to SFAS 123R. These expenses reduced operating margin by approximately 120 basis points. Had incremental stock-based compensation been included in operating expenses for the year ended December 31, 2005 under SFAS 123, operating expenses would have been $17.4 million higher and operating margins would have been approximately 150 basis points lower or 13.2% of net revenue on a pro forma basis.

Income from operations from Covance's early development segment increased $13.5 million or 9.6% to $153.6 million or 24.3% of net revenues for the year ended December 31, 2006 from $140.1 million or 24.9% of net revenues for the corresponding 2005 period. The $13.5 million increase over the prior year was driven primarily by strength in our global toxicology and chemistry services, partially offset by softness in our research products and dilution resulting from the 2006 acquisition of Radiant Research Inc. ("Radiant"). The dilutive impact on 2006 operating margins from Radiant was 100 basis points. Income from operations from Covance's late-stage development segment increased $19.0 million or 18.1% to $123.7 million for the year ended December 31, 2006 from $104.7 million for the corresponding 2005 period. Income from operations as a percentage of net revenues increased to 17.5% for the year ended December 31, 2006 from 16.6% for the corresponding 2005 period, driven by strength in our central laboratory services. Corporate expense increased $14.3 million to $84.0 million or 6.3% of net revenues for 2006 from $69.7 million or 5.8% of net revenues for 2005. Comparisons to the prior year are impacted by the inclusion of $15.5 million or 1.2% of net revenues in stock-based compensation in corporate expenses in the 2006 period pursuant to SFAS 123R. Had incremental stock-based compensation been included in corporate expenses for the year ended December 31, 2005 under SFAS 123, corporate expenses would have been $17.4 million higher, totaling $87.1 million or 7.3% of net revenue on a pro forma basis. The reduction from $87.1 million in 2005 to $84.0 million in 2006 is primarily due to lower stock-based and incentive compensation and professional fees in the year ended December 31, 2006.

Other income, net increased $4.8 million to $7.4 million for 2006 from $2.6 million for 2005 primarily as a result of a $3.9 million increase in net interest income resulting from higher invested cash balances and higher average interest rates earned on those balances in 2006.

Covance's effective tax rate for the year ended December 31, 2006 was 28.5% compared to 33.1% for the corresponding 2005 period. The effective tax rate for 2006 includes the impact of a $2.5 million reduction in income tax reserves resulting from favorable income tax developments arising in the third quarter. The 2006 effective rate also reflects increases to the tax reserves recorded during the fourth quarter of 2006 for new exposures which arose and interest on matters still outstanding totaling $2.2 million, which was offset by a reduction in income taxes payable recorded during the fourth quarter of 2006 resulting from tax return to financial statement accrual adjustments made to reflect actual amounts due upon the filing of tax returns in 2006. The effective tax rate for 2005 includes the impact of a $4.4 million income tax charge associated with the repatriation of $103 million of accumulated foreign earnings during the fourth quarter under the American Jobs Creation Act. The impact of the 2006 tax gain and 2005 tax charge on Covance's effective tax rate was a 120 basis point reduction in 2006 and a 250 basis point increase in 2005. Other factors impacting the effective tax rate from 2005 to 2006 include a shift in the mix of our pre-tax earnings across various tax jurisdictions, increased research and development tax credits in the United Kingdom and other initiatives.

Covance has a minority equity position (approximately 21% at December 31, 2006) in Bio-Imaging Technologies, Inc. ("BITI"). BITI uses proprietary medical imaging technologies to process and analyze medical images, and also provides other services, including the data-basing and regulatory submission of medical images, quantitative data and text. During the years ended December 31, 2006 and 2005, Covance recognized income of $0.02 million and a loss of $0.5 million, respectively, representing its share of BITI's results.

Covance has a 47% minority equity position in Noveprim Limited, a supplier of research products. During the years ended December 31, 2006 and 2005, Covance recognized $1.6 million and $1.3 million, respectively, representing its share of Noveprim's earnings, less an elimination of profit on inventory purchased from Noveprim Limited and still on hand at Covance at December 31, 2006 and 2005.

Net income of $145.0 million for the year ended December 31, 2006 increased $25.4 million or 21.2% as compared to $119.6 million for the corresponding 2005 period. Comparisons to the prior year are impacted by the inclusion of $10.6 million, net of tax, in stock-based compensation in the 2006 period pursuant to SFAS 123R, the tax gain of $2.5 million in 2006 and the tax charge of $4.4 million in 2005. Had incremental stock-based compensation been included in net income for the year ended December 31, 2005 under SFAS 123, and had net income in both periods excluded the tax gain/(charge), on a proforma basis, net income for the year ended December 31, 2006 would have increased $30.4 million, or 27.1%, as compared to net income for the year ended December 31, 2005.

Quarterly Results

Covance's quarterly operating results are subject to variation, and are expected to continue to be subject to variation, as a result of factors such as (1) delays in initiating or completing significant drug development trials, (2) termination or reduction in size of drug development trials, (3) acquisitions and divestitures, (4) changes in the mix of our services, and (5) exchange rate fluctuations. Delays and terminations of trials are often the result of actions taken by Covance's customers or regulatory authorities and are not typically controllable by Covance. Since a large amount of Covance's operating costs are relatively fixed while revenue is subject to fluctuation, moderate variations in the commencement, progress or completion of drug development trials may cause significant variations in quarterly results.

The following table presents unaudited quarterly operating results of Covance for each of the eight most recent fiscal quarters during the period ended December 31, 2007. In the opinion of Covance, the information in the table below has been prepared on the same basis as the audited consolidated financial statements included elsewhere in this Annual Report and reflects all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of results of operations for those periods. This quarterly financial data should be read in conjunction with the audited consolidated financial statements included elsewhere in this Annual Report. Operating results for any quarter are not necessarily indicative of the results that may be reported in any future period.

(b): Amounts include a reduction in income tax reserves resulting from favorable income tax developments totaling $2,467 (or $0.04/diluted share).

Liquidity and Capital Resources

Covance has a centralized cash management function. In the United States, cash received from operations is swept daily to a centrally managed concentration account, while cash disbursements for operations are funded as needed from the concentration account. Outside of the United States, cash balances are generally pooled by currency in order to facilitate cash management and improve investment returns. As in the United States, cash balances are generally maintained in the functional currency of the operating unit.

Cash and cash equivalents at December 31, 2007 and 2006 were $319.5 million and $219.8 million, respectively. Amounts are principally invested in short-term money market funds. Covance's expected primary cash needs on both a short and long-term basis are for capital expenditures, expansion of services, possible future acquisitions, geographic expansion, working capital and other general corporate purposes, including possible share repurchases. Covance's $75.0 million revolving credit facility (the "Credit Facility") expires in June 2009 and may be expanded to $125.0 million at Covance's election. Covance believes that cash on hand plus cash from operations will provide sufficient liquidity for the foreseeable future. At December 31, 2007, there were no outstanding borrowings and $1.1 million of outstanding letters of credit under the Credit Facility. Interest on all outstanding borrowings under the Credit Facility is based upon the London Interbank Offered Rate ("LIBOR") plus a 75 basis point margin. Costs associated with the Credit Facility consisted primarily of bank fees totaling $0.4 million which are being amortized over the five year facility term. The Credit Facility contains various financial and other covenants. At December 31, 2007, Covance was in compliance with the terms of the Credit Facility. The Credit Facility is collateralized by guarantees of certain of Covance's domestic subsidiaries and a pledge of 65 percent of the capital stock of certain of Covance's foreign subsidiaries. A commitment fee of 15 basis points on the undrawn balance of the Credit Facility is payable in arrears on the first day of each July, October, January and April, and totaled approximately $0.1 million during each of the years ended December 31, 2007 and 2006.

During the year ended December 31, 2007, Covance's operations provided net cash of $293.5 million, an increase of $39.4 million from the corresponding 2006 period. The change in net operating assets provided $40.2 million in cash during 2007, primarily due to an increase in accrued liabilities and unearned revenue, partially offset by an increase in accounts receivable, inventory and prepaids and other current assets, and a decrease in accounts payable, while this net change provided $22.4 million in cash in 2006, primarily due to an increase in accrued liabilities, unearned revenue and accounts payable, partially offset by an increase in prepaids and other current assets. Covance's ratio of current assets to current liabilities was 2.15 at December 31, 2007 and 2.21 at December 31, 2006.

Investing activities for the year ended December 31, 2007 used $165.5 million versus $211.7 million for the corresponding 2006 period. Capital spending for 2007 totaled $201.0 million, and was primarily for the expansion of our preclinical facilities in North America and Europe, outfitting of new facilities, upgrade of existing equipment, purchase of new equipment, hardware and software. Capital spending for the corresponding 2006 period totaled $136.8 million, and was primarily for the expansion of our preclinical facilities in North America and Europe, outfitting of new facilities, upgrade of existing equipment, purchase of new equipment, hardware and software for newly hired employees.

Investing activities for 2007 included the initial proceeds from the sale of Covance's cardiac safety service offering totaling $35.2 million. On November 28, 2007, Covance sold its centralized ECG business ("Cardiac Safety Services"), part of Covance's Late Stage Development segment, to eResearchTechnology Inc. ("eRT"). Covance recognized a pre-tax gain of $6.6 million ($4.1 million after tax) from this transaction. Covance and eRT also entered into a ten year marketing agreement under which Covance will continue to offer its clients cardiac safety services. Covance may receive up to an additional $14 million in future contingent consideration relating to transferred backlog and revenues generated by eRT from new contracts secured under the first three years of the marketing agreement. In addition, Covance expects to receive referral fees during the term of the long-term marketing agreement.

Investing activities for 2006 included cash payments totaling $75.7 million for the acquisitions of Radiant and Signet. In 2006, Covance acquired the stock of Radiant in a merger transaction for cash payments aggregating approximately $66.6 million (including direct acquisition costs of $0.5 million). Radiant's early development clinical sites perform Phase I/IIa clinical trial services. Results of operations for Radiant, which are now part of Covance's Early Development segment, and the fair value of Radiant's assets and liabilities acquired, are included in Covance's consolidated financial statements beginning June 1, 2006. The fair value of Radiant's net assets was $9.2 million. Intangible assets acquired were valued at $6.8 million. The remaining purchase price of $50.6 million represents goodwill.

In 2006, Covance also acquired certain assets and liabilities of Signet for cash payments totaling $9.1 million (including direct acquisition costs of $0.2 million). Signet specializes in the development of monoclonal antibodies and diagnostic assays for cancer, infectious diseases and neurodegenerative diseases. Results of operations for Signet, which are now part of Covance's Early Development segment, and the fair value of Signet's assets and liabilities acquired, are included in Covance's consolidated financial statements beginning June 1, 2006. The fair value of Signet's net assets was $0.4 million. Intangible assets acquired were valued at $0.9 million. The remaining purchase price of $7.9 million represents goodwill.

Financing activities for the year ended December 31, 2007 used $32.9 million and were comprised of the purchase into treasury of 977,000 shares of common stock in connection with a 3.0 million share buyback program authorized by Covance's Board of Directors in February 2007, and the purchase into treasury of 85,699 shares in connection with employee benefit plans, for an aggregate cost of $66.4 million, partially offset by the proceeds from the exercise of stock options of $22.2 million, excess tax benefits realized on the exercise of stock options of $6.0 million and employee contributions to Covance's employee stock purchase plan of $5.2 million. Financing activities for the year ended December 31, 2006 provided $11.9 million and were primarily comprised of proceeds from the exercise of stock options of $28.4 million, excess tax benefits realized on the exercise of stock options of $7.3 million and employee contributions to Covance's employee stock purchase plan of $4.2 million, partially offset by the purchase into treasury of 414,100 shares of common stock in connection with a 3.0 million share buyback program authorized by Covance's Board of Directors in June 2004, and the purchase into treasury of 68,829 shares in connection with employee benefit plans, for an aggregate cost of $28.0 million. At December 31, 2007, there are approximately 2.3 million shares remaining for repurchase under the Board authorized buyback program.

The effect of exchange rate changes on cash for the year ended December 31, 2007 was an increase of $4.6 million versus an increase of $4.7 million for the prior year. Covance's cash balances increased by $99.7 million during 2007.

As discussed in Note 11 to the audited consolidated financial statements included elsewhere in this Annual Report, and as set forth in the table below, Covance is obligated under non-cancelable operating leases, primarily for its offices and laboratory facilities. Covance is also obligated under outsourcing agreements related to certain aspects of its information technology and human resources support functions and purchase commitments related to the completion of ongoing facility expansions, both of which are reflected under the caption purchase obligations in the table below. Actual amounts paid under these outsourcing agreements could be higher or lower than the amounts shown below as a result of changes in volume and other variables. In addition, early termination of these outsourcing agreements by Covance could result in the payment of termination fees which are not reflected in the table below.

	Payments due by period

Contractual Obligations^(a)	Total		<1 Year		1-3 Years		3-5 Years		> 5 Years
	(Dollars in thousands)
Operating Leases	$	145,536	$	24,520	$	39,561	$	26,685	$	54,770
Purchase Obligations		131,505		80,476		39,991		8,114		2,924

Total	$	277,041	$	104,996	$	79,552	$	34,799	$	57,694

(a): Excludes $8.9 million, including $1.3 million in interest, related to accruals under FIN 48, of which $2.6 million may become due in less than one year, and the remainder of which, the period of cash settlement cannot be reasonably estimated.

Off-Balance Sheet Arrangements

At December 31, 2007 and 2006, Covance was not a party to any off-balance sheet arrangements as defined by Regulation S-K Item 303(a)(4)(i), promulgated under the Exchange Act.

Inflation

While most of Covance's net revenues are earned under contracts, the long-term contracts (those in excess of one year) generally include an inflation or cost of living adjustment for the portion of the services to be performed beyond one year from the contract date. As a result, Covance believes that the effects of inflation generally do not have a material effect on its operations or financial condition.

Recently Issued Accounting Standards

In September 2006, the Financial Accounting Standards Board (the "FASB") issued Statement of Financial Accounting Standards No. 158, Employers' Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106 and 132(R), ("SFAS 158"). As of December 31, 2006, Covance has adopted the recognition and disclosure provisions of SFAS 158, which require an employer to recognize the over funded or under funded status of its defined benefit postretirement plans—measured as the difference between the fair value of plan assets and the projected benefit obligation—as an asset or liability, respectively, in its balance sheet and to recognize changes in the funded status of the plan in the year in which such changes occur through other comprehensive income. The adoption of SFAS 158 did not have an impact on our consolidated results of operations. SFAS 158 also requires, effective for fiscal years ending after December 15, 2008, that the measurement of the over funded or under funded status of a plan be made as of the employer's fiscal year end and not as of an earlier measurement date. Covance will be required to conform the measurement dates of its plans to December 31^st for its fiscal year ending December 31, 2008. Covance does not expect this change in measurement dates to have a material impact on its consolidated results of operations or financial position.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements, ("SFAS 157"). SFAS 157, which applies whenever other standards require (or permit) fair value measurement, defines fair value and provides guidance for using fair value to measure assets and liabilities. SFAS 157 also requires expanded disclosures about the extent to which companies measure assets and liabilities at fair value, the information used in those measurements and the effect of fair value measurements on earnings. Covance will be required to adopt SFAS 157, which is effective for fiscal years beginning after November 15, 2007, no later than the quarter beginning January 1, 2008. Covance does not expect the adoption of SFAS 157 to have a material impact on its consolidated results of operations or financial position.

In December 2007, the FASB issued SFAS No. 141 (revised 2007), Business Combinations ("SFAS 141R") which replaces SFAS No. 141, Business Combinations. The scope of SFAS 141R is broader than that of SFAS No. 141, which applied only to business combinations in which control was obtained by transferring consideration. SFAS 141R revises accounting and reporting standards for business combinations and applies to all transactions or other events in which an entity obtains control of one or more businesses by transferring consideration as well as combinations achieved without the transfer of consideration. By applying the same method of accounting—the acquisition method—to all transactions and other events in which one entity obtains control over one or more other businesses, this statement is intended to improve the comparability of the information about business combinations provided in financial reports. SFAS 141R applies prospectively to business combinations with an acquisition date on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. Covance is currently in the process of evaluating SFAS 141R, and has not yet determined the impact, if any, that accounting for future business combinations under SFAS 141R, effective January 1, 2009, will have on its consolidated results of operations or financial position.

In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements—an amendment of ARB No. 51 ("SFAS 160"). SFAS 160 amends ARB No. 51 to establish accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. Covance will be required to adopt SFAS 160, which is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008, in the quarter beginning January 1, 2009. Covance is currently in the process of evaluating SFAS 160, and has not yet determined the impact, if any, SFAS 160 will have on its consolidated results of operations or financial position.

Forward Looking Statements. Statements in this Management's Discussion and Analysis of Financial Condition and Results of Operations, as well as in certain other parts of this Annual Report on Form 10-K that look forward in time, are forward looking statements made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward looking statements include statements concerning plans, objectives, goals, strategies, future events or performance, expectations, predictions, and assumptions and other statements which are other than statements of historical facts. All such forward looking statements are based on the current expectations of management and are subject to, and are qualified by, risks and uncertainties that could cause actual results to differ materially from those expressed or implied by those statements.

Item 7a. Quantitative and Qualitative Disclosures About Market Risk

For the year ended December 31, 2007, approximately 38% of our net revenues were derived from our operations outside the United States. We do not engage in derivative or hedging activities related to our potential foreign exchange exposures. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Foreign Currency" for a more detailed discussion of our foreign currency risks and exposures.

Management's Report on Consolidated Financial Statements and Internal Control

The management of Covance Inc. ("Covance") has prepared, and is responsible for, Covance's consolidated financial statements and related footnotes. These consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles.

Covance's management is responsible for establishing and maintaining effective internal control over financial reporting and for assessing the effectiveness of internal control over financial reporting. The purpose of this system of internal accounting controls over financial reporting is to provide reasonable assurance that assets are safeguarded, that transactions are executed in accordance with management's authorization and are properly recorded, and that accounting records may be relied upon for the preparation of accurate and complete consolidated financial statements. The design, monitoring and revision of internal accounting control systems involve, among other things, management's judgment with respect to the relative cost and expected benefits of specific control measures. Covance also maintains an internal audit function that evaluates and reports on the adequacy and effectiveness of internal controls, policies and procedures.

Covance's management concluded that its internal control over financial reporting as of December 31, 2007 was effective and adequate to accomplish the objectives described above. Management's assessment was based upon the criteria in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Covance's consolidated financial statements and the effectiveness of control over financial reporting have been audited by an independent registered public accounting firm, Ernst & Young LLP, as stated in their reports which are included elsewhere herein.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders
Covance Inc.

We have audited Covance Inc.'s internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Covance Inc.'s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying report on consolidated financial statements and internal control. Our responsibility is to express an opinion on the company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Covance Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Covance Inc. and subsidiaries as of December 31, 2007 and 2006, and the related consolidated statements of income, shareholders' equity, and cash flows for each of the three years in the period ended December 31, 2007 and our report dated February 21, 2008 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders
Covance Inc.

We have audited the accompanying consolidated balance sheets of Covance Inc. and subsidiaries as of December 31, 2007 and 2006, and the related consolidated statements of income, shareholders' equity, and cash flows for each of the three years in the period ended December 31, 2007. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Covance Inc. and subsidiaries at December 31, 2007 and 2006, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2007, in conformity with U.S. generally accepted accounting principles.

As discussed in Note 2 to the consolidated financial statements, in 2006 the Company adopted SFAS No. 123(R), "Share-Based Payments" applying the modified prospective method at the beginning of fiscal year 2006. Also, as discussed in Note 2 to the consolidated financial statements, the Company adopted SFAS No. 158, "Employers' Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106 and 132(R)" at the end of fiscal year 2006, and FIN 48, "Accounting for Uncertainty in Income Taxes—an Interpretation of FASB Statement No. 109", as of January 1, 2007.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of Covance Inc.'s internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 21, 2008 expressed an unqualified opinion thereon.

DECEMBER 31, 2007, 2006 AND 2005
(Dollars in thousands, unless otherwise indicated)

1. Organization

Covance Inc. and its subsidiaries ("Covance" or the "Company") is a leading drug development services company providing a wide range of early-stage and late-stage product development services on a worldwide basis primarily to the pharmaceutical, biotechnology and medical device industries. Covance also provides services such as laboratory testing to the chemical, agrochemical and food industries. Covance's operations constitute two segments for financial reporting purposes. The first segment, early development services, includes preclinical and clinical pharmacology service offerings. The second segment, late-stage development services, includes central laboratory, clinical development, periapproval and market access services. Operations are principally focused in the United States and Europe.

2. Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of all entities controlled by Covance. All significant intercompany accounts and transactions are eliminated. The equity method of accounting is used for investments in affiliates in which Covance owns between 20 and 50 percent and does not have the ability to exercise control. See Note 5.

Use of Estimates

These consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles ("GAAP"), which requires management to make estimates and assumptions about future events that affect the amounts reported in the financial statements and the accompanying notes. Actual results could differ from these estimates.

Foreign Currencies

For subsidiaries outside of the United States that operate in a local currency environment, income and expense items are translated to United States dollars at the monthly average rates of exchange prevailing during the year, assets and liabilities are translated at year-end exchange rates and equity accounts are translated at historical exchange rates. Translation adjustments are accumulated in a separate component of stockholders' equity in the Consolidated Balance Sheets and are included in the determination of comprehensive income in the Consolidated Statements of Stockholders' Equity. Transaction gains and losses are included in the determination of net income in the Consolidated Statements of Income.

Cash and Cash Equivalents

Cash and cash equivalents include all highly liquid investments with an original maturity of three months or less at date of purchase and consist principally of amounts invested in money market funds.

Financial Instruments

The fair value of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate their carrying amounts as reported at December 31, 2007 and 2006.

DECEMBER 31, 2007, 2006 AND 2005
(Dollars in thousands, unless otherwise indicated)

2. Summary of Significant Accounting Policies (Continued)

Accounts receivable and unbilled services represent amounts due from Covance customers who are concentrated primarily in the pharmaceutical and biotechnology industries. Covance endeavors to monitor the creditworthiness of its customers to which it grants credit terms in the ordinary course of business. Although Covance customers are concentrated primarily within these two industries, management considers the likelihood of material credit risk as remote. In addition, in some cases Covance requires advance payment for a portion of the contract price from its customers upon the signing of a contract for services. These amounts are deferred and recognized as revenue as services are performed. Historically, bad debts have been immaterial.

Inventory

Inventories, which consist principally of finished goods and supplies, are valued at the lower of cost (first-in, first-out method) or market.

Prepaid Expenses and Other Current Assets

In connection with the management of multi-site clinical trials, Covance pays on behalf of its customers fees to investigators, volunteers and other out-of-pocket costs (such as travel, printing, meetings, couriers, etc.), for which we are reimbursed at cost, without mark-up or profit. Amounts receivable from customers in connection with billed and unbilled investigator fees, volunteer payments and other out-of-pocket pass-through costs are included in prepaid expenses and other current assets in the accompanying Consolidated Balance Sheets and totaled $47.4 million and $37.7 million at December 31, 2007 and 2006, respectively. See Note 2 "Reimbursable Out-of-Pocket Expenses".

Property and Equipment

Property and equipment are recorded at cost. Depreciation and amortization are provided on the straight-line method at rates adequate to allocate the cost of the applicable assets over their estimated useful lives, which generally range from ten to forty years for buildings and improvements, three to ten years for equipment, furniture and fixtures and three to five years for computer hardware and software, except for certain large enterprise-wide software applications which are depreciated over eight years. Leasehold improvements are capitalized and amortized on a straight-line basis over the shorter of the estimated useful life of the improvement or the associated remaining lease term. The cost of computer software developed or obtained for internal use is accounted for in accordance with the Accounting Standards Executive Committee's Statement of Position 98-1, Accounting for the Costs of Computer Software Developed or Obtained for Internal Use. Repairs and maintenance are expensed as incurred.

Goodwill and Other Intangible Assets and Impairment

Goodwill represents costs in excess of the fair value of net tangible and identifiable net intangible assets acquired in business combinations. In accordance with Statement of Financial Accounting Standards ("SFAS") No. 142, Goodwill and Other Intangible Assets, Covance performs an annual test for impairment of goodwill and other indefinite lived intangible assets during the fourth quarter. This test is performed by comparing, at the reporting unit level, the carrying value of the reporting unit to its fair value. Covance assesses fair value based upon its estimate of the present value of the future cash flows that it expects to be generated by the reporting unit. The annual test for impairment performed for 2007, 2006 and 2005 did not identify any instances of impairment.

(Dollars in thousands, unless otherwise indicated)

2. Summary of Significant Accounting Policies (Continued)

Intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives, which range in term from one to ten years. The Company periodically evaluates the reasonableness of the estimated useful lives of these intangible assets. See Note 4.

Impairment of Long-Lived Assets

Covance assesses impairment of long-lived assets in accordance with SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets. Assessments of the recoverability of long-lived assets are conducted when events or changes in circumstances occur that indicate the carrying value of the asset may not be recoverable. The assessment of possible impairment is based upon the ability to recover the asset from the expected future undiscounted cash flows of related operations. No events have been identified that caused an evaluation of the recoverability of the long-lived assets for the years ended December 31, 2007, 2006 and 2005.

Revenue Recognition

Covance recognizes revenue either as services are performed or products are delivered, depending upon the nature of the work contracted. Historically, a majority of Covance's net revenues have been earned under contracts which range in duration from a few months to two years, but can extend in duration up to five years or longer. Service contracts generally take the form of fee-for-service or fixed-price arrangements. In the case of fee-for-service contracts, revenue is recognized as services are performed, based upon, for example, hours worked or samples tested. For long-term fixed-price service contracts, revenue is recognized as services are performed, with performance generally assessed using output measures, such as units-of-work performed to date as compared to the total units-of-work contracted. Changes in the scope of work generally result in a renegotiation of contract pricing terms. Renegotiated amounts are not included in net revenues until earned and realization is assured. Estimates of costs to complete are made to provide, where appropriate, for losses expected on contracts. Costs are not deferred in anticipation of contracts being awarded, but instead are expensed as incurred. In some cases, a portion of the contract fee is paid at the time the trial is initiated. These advances are deferred and recognized as revenue as services are performed or products are delivered, as discussed above. Additional payments may be made based upon the achievement of performance-based milestones over the contract duration. Most contracts are terminable by the client either immediately or upon notice. These contracts typically require payment to Covance of expenses to wind down the study, fees earned to date and, in some cases, a termination fee or a payment to Covance of some portion of the fees or profits that could have been earned by Covance under the contract if it had not been terminated early. Termination fees are included in net revenues when realization is assured. In connection with the management of multi-site clinical trials, Covance pays on behalf of its customers fees to investigators, volunteers and other out-of-pocket costs (such as for travel, printing, meetings, couriers, etc.), for which it is reimbursed at cost, without mark-up or profit. Investigator fees are not reflected in total revenues or expenses where Covance acts in the capacity of an agent on behalf of the pharmaceutical company sponsor, passing through these costs without risk or reward to Covance. All other out-of-pocket costs are included in total revenues and expenses.

Unbilled services are recorded for revenue recognized to date and relate to amounts that are currently unbillable to the customer pursuant to contractual terms. In general, amounts become billable upon the achievement of milestones or in accordance with predetermined payment schedules. Unbilled services are billable to customers within one year from the respective balance sheet date. Unearned revenue is recorded for cash received from customers for which revenue has not been recognized at the balance sheet date.

2. Summary of Significant Accounting Policies (Continued)

Costs and Expenses

Cost of revenue includes direct labor and related benefit charges, other direct costs, shipping and handling fees, and an allocation of facility charges and information technology costs and excludes depreciation and amortization. Selling, general and administrative expenses consist primarily of administrative payroll and related benefit charges, advertising and promotional expenses, administrative travel and an allocation of facility charges and information technology costs and excludes depreciation and amortization. Cost of advertising is expensed as incurred.

Taxes

Covance uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax bases using enacted tax rates in effect for the year in which the temporary differences are expected to reverse. The effect on deferred taxes of a change in enacted tax rates is recognized in income in the period when the change is effective. See Note 7.

The Company also maintains a tax reserve related to exposures for non-income tax matters including value added tax and state sales and use and other taxes, which are accounted for in accordance with Statement of Financial Accounting Standards No. 5, Accounting for Contingencies. The balance of this reserve at December 31, 2007 is $0.8 million and is recorded as a current liability in accrued expenses and other current liabilities on the Consolidated Balance Sheet. This reserve was reduced by $0.3 million from the January 1, 2007 balance of $1.1 million, primarily from the settlement of state and foreign audits, partially offset by the accrual of interest on outstanding reserves in 2007.

While Covance believes it has identified all reasonably identifiable exposures and the reserve it has established for identifiable exposures is appropriate under the circumstances, it is possible that additional exposures exist and that exposures may be settled at amounts different than the amounts reserved. It is also possible that changes in facts and circumstances could cause Covance to either materially increase or reduce the carrying amount of its tax reserves.

2. Summary of Significant Accounting Policies (Continued)

Covance's historical policy has been to leave its unremitted foreign earnings invested indefinitely outside the United States. Except for the one-time opportunity provided under the American Jobs Creation Act, pursuant to which Covance repatriated $103 million in accumulated foreign earnings in the fourth quarter of 2005, Covance intends to continue to leave its unremitted foreign earnings invested indefinitely outside the United States. As a result, taxes have not been provided on any of the remaining accumulated foreign unremitted earnings as of December 31, 2007. See Note 7.

Comprehensive Income

Covance's total comprehensive income represents net income plus the change in the cumulative translation adjustment equity account for the periods presented. For the year ended December 31, 2007, comprehensive income also includes adjustments net of tax, for the current year actuarial gains and prior service credits in accordance with SFAS 158. For the year ended December 31, 2006, accumulated other comprehensive income also includes the adjustment resulting from the adoption of Statement of Financial Accounting Standards No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106 and 132(R), ("SFAS 158") to record the under funded status of the Company's defined benefit postretirement plans on its balance sheet at December 31, 2006, net of tax.

Stock-Based Compensation

The Company sponsors several stock-based compensation plans pursuant to which non-qualified stock options and restricted stock awards are granted to eligible employees. These plans are described more fully in Note 10.

Through the year ended December 31, 2005, the Company followed the disclosure-only provisions of Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation, ("SFAS 123"), and, accordingly, accounted for awards under these plans pursuant to the recognition and measurement principles of Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees, ("APB 25") and related Interpretations, as permitted by SFAS 123. Under APB 25, compensationexpense was recognized in the financial statements relating to awards of stock. However, no compensation expense was recorded in the financial statements for stock option grants, as all options had been granted with an exercise price equal to the market value of the underlying common stock on the date of grant. Additionally, no compensation expense was recorded in the financial statements for shares purchased by employees under the Company's Employee Stock Purchase Plan as that plan was considered to be non-compensatory under APB 25.

Effective January 1, 2006, the Company adopted the fair value recognition provisions of Statement of Financial Accounting Standards No. 123R, Share-Based Payments, ("SFAS 123R") using the modified prospective transition method. SFAS 123R revised SFAS 123, superseded APB 25 and amended Statement of Financial Accounting Standards No. 95, Statement of Cash Flows. Under the modified prospective transition method, compensation expense is recognized in the financial statements on a prospective basis for (a) all share-based payments granted prior to, but not vested as of January 1, 2006, based upon the grant-date fair value estimated in accordance with the original provisions of SFAS 123, and (b) share-based payments granted on or subsequent to January 1, 2006, based upon the grant-date fair value estimated in accordance with the provisions of SFAS 123R. The grant-date fair value of awards expected to vest is expensed on a straight-line basis over the vesting period of the related awards. Under the modified prospective transition method, results for prior periods are not restated.

2. Summary of Significant Accounting Policies (Continued)

Earnings Per Share ("EPS")

Basic EPS is computed by dividing net income available to common stockholders by the weighted average number of shares outstanding during the period. The computation of diluted EPS is similar to the computation of basic EPS, except that the denominator is increased to include the number of additional common shares that would have been outstanding if the dilutive potential common shares had been issued; computed under the treasury stock method in accordance with the requirements of SFAS No. 128, Earnings Per Share.

In computing diluted EPS for the years ended December 31, 2007, 2006 and 2005, the denominator was increased by 1,072,674 shares, 1,196,490 shares and 1,170,734 shares, respectively, representing the dilutive effect of stock options outstanding at December 31, 2007, 2006 and 2005, with exercise prices less than the average market price of Covance's common stock during each respective period. Excluded from the computation of diluted EPS for the year ended December 31, 2007 were options to purchase 4,805 shares of common stock at prices ranging from $70.57 to $87.33 per share because the exercise prices of such options were greater than the average market price of Covance's common stock during 2007. Excluded from the computation of diluted EPS for the year ended December 31, 2006 were options to purchase 12,263 shares of common stock at prices ranging from $61.26 to $66.86 per share because the exercise prices of such options were greater than the average market price of Covance's common stock during 2006. Excluded from the computation of diluted EPS for the year ended December 31, 2005 were options to purchase 54,617 shares of common stock at prices ranging from $47.27 to $52.71 per share because the exercise prices of such options were greater than the average market price of Covance's common stock during 2005.

Reimbursable Out-of-Pocket Expenses

As discussed in Note 2 "Prepaid Expenses and Other Current Assets", Covance pays on behalf of its customers fees to investigators, volunteers and other out-of-pocket costs for which we are reimbursed at cost, without mark-up or profit. In connection with the requirements of Financial Accounting Standards Board Emerging Issues Task Force Rule No. 01-14 ("EITF 01-14"), Income Statement Characterization of Reimbursements Received for "Out-of-Pocket" Expenses Incurred, amounts paid to volunteers and other out-of-pocket costs are reflected in operating expenses, while the reimbursements received are reflected in revenues in the Consolidated Statements of Income. Covance will continue to exclude from revenue and expense in the Consolidated Statements of Income fees paid to investigators and the associated reimbursement since Covance acts as an agent on behalf of the pharmaceutical company sponsors with regard to investigator payments.

2. Summary of Significant Accounting Policies (Continued)

Supplemental Cash Flow Information

Cash paid for interest for the years ended December 31, 2007, 2006 and 2005 totaled $0.3 million, $0.2 million and $0.2 million, respectively. Cash paid for income taxes for the years ended December 31, 2007, 2006 and 2005 totaled $63.2 million, $47.8 million and $25.2 million, respectively. The change in income taxes payable in the consolidated statement of cash flows for the years ended December 31, 2007 and 2006 includes as an operating cash outflow the excess tax benefit received from the exercise of non-qualified stock options as measured under SFAS 123R of $6.0 million and $7.4 million, respectively (a corresponding cash inflow of $6.0 million and $7.4 million, respectively, has been included in financing cash flows). The change in income taxes payable in the Consolidated Statement of Cash flows for the year ended December 31, 2005 reflects the full tax benefit received from the exercise of non-qualified stock options of $11.7 million as measured and accounted for under SFAS 123 and APB 25. Pursuant to those standards, both the reduction in income taxes payable and the increase in equity resulting from the full tax benefit received are reflected in operating cash flows.

Recently Issued Accounting Standards

In September 2006, the Financial Accounting Standards Board (the "FASB") issued Statement of Financial Accounting Standards No. 158, Employers' Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106 and 132(R), ("SFAS 158"). As of December 31, 2006, Covance adopted the recognition and disclosure provisions of SFAS 158, which require an employer to recognize the over funded or under funded status of its defined benefit postretirement plans—measured as the difference between the fair value of plan assets and the projected benefit obligation—as an asset or liability, respectively, in its balance sheet and to recognize changes in the funded status of the plan in the year in which such changes occur through other comprehensive income. SFAS 158 also requires, effective for fiscal years ending after December 15, 2008, that the measurement of the over funded or under funded status of a plan be made as of the employer's fiscal year end and not as of an earlier measurement date. Covance will be required to conform the measurement dates of its plans to December 31 for its fiscal year ending December 31, 2008. Covance does not expect this change in measurement dates to have a material impact on its consolidated results of operations or financial position.

5. Equity Method Investees

Covance has a 47% minority equity position in Noveprim Limited, a supplier of research products, which was acquired in March 2004 at a total cost of $20.7 million. The excess of the purchase price over the underlying equity in Noveprim's net assets at the date of acquisition of $13.8 million represents goodwill and is included in the carrying value of Covance's investment. This investment is reflected in Other Assets on the Consolidated Balance Sheet. During the years ended December 31, 2007, 2006 and 2005, Covance recognized income of $2.0 million, $1.6 million and $1.3 million, respectively, representing its share of Noveprim's earnings, less the elimination of profit on inventory purchased from Noveprim Limited and still on hand at Covance at December 31, 2007, 2006 and 2005. The carrying value of Covance's investment in Noveprim as of December 31, 2007 and 2006 was $23.2 million and $23.0 million, respectively.

Covance has a minority equity position (approximately 20% at December 31, 2007) in Bio-Imaging Technologies, Inc. ("BITI"). BITI uses proprietary medical imaging technologies to process and analyze medical images, and also provides other services, including the data-basing and regulatory submission of medical images, quantitative data and text. During the years ended December 31, 2007, 2006 and 2005, Covance recognized income of $0.4 million, income of $0.02 million and a loss of $0.5 million, respectively, representing its pro rata share of BITI's earnings. The carrying value of Covance's investment in BITI at December 31, 2007 and 2006 was $0.9 million and $0.5 million, respectively, while the fair market value was $19.0 million at the end of each year.

6. Acquisitions and Divestitures

On November 28, 2007, Covance sold its centralized ECG business ("Cardiac Safety Services"), part of Covance's Late Stage Development segment, to eResearchTechnology Inc. ("eRT") for an initial payment of $35.2 million. Covance recognized a pre-tax gain of $6.6 million ($4.1 million after tax) from this transaction. Covance and eRT also entered into a ten year marketing agreement under which Covance will continue to offer its clients cardiac safety services. Covance may receive up to an additional $14 million in future contingent consideration relating to transferred backlog and revenues generated by eRT from new contracts secured under the first three years of the marketing agreement. In addition, Covance expects to receive referral fees during the term of the long-term marketing agreement.

In May 2006, Covance acquired the stock of Radiant Research Inc. ("Radiant") in a merger transaction for cash payments aggregating $66.6 million (including direct acquisition costs of $0.5 million). The Radiant acquisition included eight early development clinical sites performing Phase I/IIa clinical trial services. Results of operations for Radiant, which are now part of Covance's Early Development segment service offering, and the fair value of Radiant's assets and liabilities acquired, are included in Covance's consolidated financial statements beginning in June 2006.

In May 2006, Covance also acquired certain assets and liabilities of Signet Laboratories, Inc. ("Signet") for cash payments totaling $9.1 million (including direct acquisition costs of $0.2 million). Signet specializes in the development of monoclonal antibodies and diagnostic assays for cancer, infectious diseases and neurodegenerative diseases. Results of operations for Signet, which are now part of Covance's Early Development segment service offering, and the fair value of Signet's assets and liabilities acquired, are included in Covance's consolidated financial statements beginning in June 2006.

7. Taxes on Income (Continued)

The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and liabilities at December 31, 2007 and 2006 are as follows:

	2007			2006

Current deferred tax assets:
Liabilities/expenses not currently deductible	$	6,707		$	3,668
Net operating losses		1,118			652

Total current deferred tax assets	$	7,825		$	4,320

Non-current deferred taxes:
Deferred tax assets:
Net operating losses	$	11,237		$	14,197
Liabilities/expenses not currently deductible		12,710			15,688

Total non-current deferred tax assets		23,947			29,885

Deferred tax liabilities:
Property and equipment		(53,106	)		(57,798	)
Earnings not currently taxable		(3,403	)		(3,139	)

Total non-current deferred tax liabilities		(56,509	)		(60,937	)

Net non-current deferred tax liabilities	$	(32,562	)	$	(31,052	)

During the year ended December 31, 2007, the United Kingdom and Germany enacted reductions to their corporate income tax rates which resulted in a revaluation of the deferred tax liabilities and assets attributable to these jurisdictions. The United Kingdom corporate income tax rate was reduced by 200 basis points and as a result, Covance recorded income tax benefits totaling $2.0 million. The German corporate tax rate was reduced by approximately 1,000 basis points and as a result, Covance recorded income tax benefits totaling $1.2 million. These income tax benefits are reflected as a reduction to international income tax expense for the year ended December 31, 2007 which was primarily offset by a shift in the mix of our pre-tax earnings to tax jurisdictions with higher income tax rates.

As of December 31, 2007, Covance has United States net operating loss carryforwards of $13.9 million relating to the acquisition of Radiant, and $24.3 million of United Kingdom net operating loss carryforwards arising from research and development expenditures and accelerated depreciation. The United States net operating loss carryforwards are subject to limitation under Internal Revenue Code §382 and will expire at various dates through 2026. The United Kingdom net operating loss carryforwards do not expire. It is expected that the entire United States and United Kingdom loss carryforwards will be realized, and accordingly, no valuation allowance has been provided.

On October 22, 2004, the American Jobs Creation Act of 2004 (the "Act") was signed into law. Among other things, the Act provided a temporary incentive for multi-national companies to repatriate previously unremitted foreign earnings by allowing companies a special one-time tax deduction equal to 85% of qualified foreign earnings that were repatriated. During the fourth quarter of 2005, Covance repatriated $103 million in foreign earnings under the Act, which resulted in the recording of an income tax charge of $4.4 million (or $0.07/diluted share).

7. Taxes on Income (Continued)

Covance currently provides income taxes on the earnings of foreign subsidiaries to the extent those earnings are taxable or are expected to be remitted. Covance's historical policy has been to leave its unremitted foreign earnings invested indefinitely outside the United States. Except for the amounts repatriated in the fourth quarter of 2005 under the Act, Covance intends to continue to leave its unremitted foreign earnings invested indefinitely outside the United States. It is not practical to estimate the amount of additional tax that might be payable if such accumulated earnings were remitted. Additionally, if such accumulated earnings were remitted, certain countries impose withholding taxes that, subject to certain limitations, are available for use as a tax credit against any Federal income tax liability arising from such remittance. As a result, taxes have not been provided on the remaining accumulated foreign unremitted earnings totaling approximately $267 million at December 31, 2007.

8. Credit Facility

Covance has a $75.0 million revolving credit facility (the "Credit Facility"), which expires in June 2009. At both December 31, 2007 and 2006, there were no outstanding borrowings under the Credit Facility. At December 31, 2007 and 2006, there were $1.1 million and $0.8 million, respectively, of outstanding letters of credit under the Credit Facility.

At December 31, 2007, Covance was in compliance with the terms of the Credit Facility, including all financial covenants. Commitment fees paid during 2007, 2006 and 2005, which under the Credit Facility are 15 basis points on the undrawn balance, approximated $0.1 million in each year. The Credit Facility is collateralized by guarantees of certain of Covance's domestic subsidiaries and a pledge of 65 percent of the capital stock of certain of Covance's foreign subsidiaries.

9. Employee Benefit Plans

Covance sponsors various pension and other post-retirement benefit plans.

Defined Benefit Pension Plans

Covance sponsors two defined benefit pension plans for the benefit of its employees at two United Kingdom subsidiaries and one defined benefit pension plan for the benefit of its employees at a German subsidiary, all of which are legacy plans of previously acquired companies. Benefit amounts for all three plans are based upon years of service and compensation. The German plan is unfunded and has a measurement date of September 30, while the United Kingdom pension plans are funded and have a measurement date of December 31. Covance's funding policy has been to contribute annually a fixed percentage of the eligible employee's salary at least equal to the local statutory funding requirements. The components of net periodic pension cost for these plans for 2007, 2006 and 2005 are as follows:

	United Kingdom Plans									German Plan

	2007			2006			2005			2007			2006			2005
Components of Net Periodic Pension Cost:
Service cost	$	5,957		$	5,878		$	4,908		$	512		$	416		$	346

Salary increases		4.00	%		4.00	%		4.00	%		2.65	%		2.50	%		2.50	%

The weighted average expected long term rate of return on the assets of the United Kingdom pension plans is based on the target asset allocation and the average rate of growth expected for the asset classes invested. The weighted average rate of expected growth is derived from a combination of historic returns, current market indicators, the expected risk premium for each asset class over the risk-free rate and the opinion of professional advisors.

Salary increases		4.25	%		4.00	%		3.00	%		2.50	%

The accumulated benefit obligation for the United Kingdom pension plans was $126,396 and $116,236 at December 31, 2007 and 2006, respectively. The accumulated benefit obligation for the German plan was $6,464 and $5,725 at December 31, 2007 and 2006, respectively.

The investment policies for the United Kingdom pension plans are set by the plan trustees, based upon the guidance of professional advisors and after consultation with the Company, taking into consideration the plans' liabilities and future funding levels. The trustees have set the long-term investment policy largely in accordance with the asset allocation of a broadly diversified investment portfolio. Assets are invested within the target ranges as follows:


Equity securities		51%–61%
Debt securities		31%–44%
Real estate		0%–9%
Other		0%–5%

The weighted average asset allocation of the United Kingdom pension plans as of December 31, 2007 and 2006 by asset category is as follows:



Equity securities	56	%	56	%
Debt securities	32	%	37	%
Real estate	7	%	3	%
Other	5	%	4	%

Total	100	%	100	%

Investments are made in pooled investment funds. Pooled investment fund managers are regulated by the Financial Services Authority in the United Kingdom and operate under terms which contain restrictions on the way in which the portfolios are managed and require the managers to ensure that suitable internal operating procedures are in place. The trustees have set performance objectives for each fund manager and routinely monitor and assess the managers' performance against such objectives.

Covance expects to contribute $6,212 to its United Kingdom plans in 2008. No contributions are expected to be made to the German plan, since that plan is unfunded.

Supplemental Executive Retirement Plan

In addition to these foreign defined benefit pension plans, Covance also has a non-qualified Supplemental Executive Retirement Plan ("SERP"). The SERP, which is not funded, is intended to provide retirement benefits for certain executive officers of Covance. Benefit amounts are based upon years of service and compensation of the participating employees. The measurement date for the SERP is November 30.

Post-Employment Retiree Health and Welfare Plan

Covance also sponsors a post-employment retiree health and welfare plan for the benefit of eligible employees at certain U.S. subsidiaries who retire after satisfying service and age requirements. This plan is funded on a pay-as-you-go basis and the cost of providing these benefits is shared with the retirees. The measurement date for this plan is November 30.

We do not anticipate any of the net actuarial loss related to the retiree health and welfare plan to be amortized from accumulated other comprehensive income into net periodic pension cost in 2008.

A one-percentage-point increase or decrease in the assumed health care cost trend rate would not impact the net service and interest cost components of the net periodic post-retirement benefit cost or the post-retirement benefit obligation since future increases in plan costs are paid by participant contributions. Covance expects to contribute $584 to the post-employment retiree health and welfare plan in 2008.

Expected future gross benefit payments, Federal subsidies and net benefit payments are as follows:

Defined Contribution Plans

U.S. employees are eligible to participate in Covance's 401(k) plan, while employees in international locations are eligible to participate in either defined benefit or defined contribution plans, depending on the plan offered at their location. Aggregate Covance contributions to its various defined contribution plans totaled $20.9 million, $17.1 million and $14.6 million for 2007, 2006 and 2005, respectively.

10. Stockholders' Equity

Preferred Stock

Covance is authorized to issue up to 10.0 million shares of Series Preferred Stock, par value $1.00 per share (the "Covance Series Preferred Stock"). The Covance Board of Directors has the authority to issue such shares from time to time, without stockholder approval, and to determine the designations, preferences, rights, including voting rights, and restrictions of such shares, subject to the Delaware General Corporate Laws. Pursuant to this authority, the Covance Board of Directors has designated 1.0 million shares of the Covance Series Preferred Stock as Covance Series A Preferred Stock. No other class of Covance Series Preferred Stock has been designated by the Board. As of December 31, 2007, no Covance Series Preferred Stock has been issued or is outstanding.

Dividends—Common Stock

Covance's Board of Directors may declare dividends on the shares of Covance common stock out of legally available funds (subject to any preferential rights of any outstanding Covance Series Preferred Stock). However, Covance has no present intention to declare dividends, but instead intends to retain earnings to provide funds for the operation and expansion of its business.

Treasury Stock

In February 2007, the Covance Board of Directors authorized the repurchase of an additional 3.0 million shares under Covance's stock repurchase program. For the years ended December 31, 2007, 2006, and 2005, Covance repurchased 1.0 million shares, 0.4 million shares, and 1.2 million shares, respectively, under Covance's stock repurchase program. At December 31, 2007 there were 2.3 million shares remaining for purchase under the 2007 authorization. Covance also reacquires shares of its common stock in connection with certain employee benefit plans primarily when employees tender shares to satisfy income tax withholdings associated with the vesting of stock awards. The following table sets forth the treasury stock activity during 2007, 2006 and 2005:

Stock-Based Compensation Plans

In May 2007, Covance's shareholders approved the 2007 Employee Equity Participation Plan (the "2007 EEPP") in replacement of the 2002 Employee Equity Participation Plan (the "2002 EEPP"). Effective upon approval of the 2007 EEPP, no further grants or awards were permitted under the 2002 EEPP. Shares remaining for grant under the 2002 EEPP will be available for grant under the 2007 EEPP. In addition, the Covance Board of Directors directed that, effective May 3, 2007, no further grants would be permitted under the 2002 Employee Stock Option Plan (the "2002 ESOP") and, unlike the 2002 EEPP, shares remaining for grant under the 2002 ESOP would not be available for grant under the 2007 EEPP. The 2007 EEPP became effective on May 3, 2007 and will expire on May 2, 2017. The 2007 EEPP authorizes the Compensation and Organization Committee of the Board of Directors (the "Compensation Committee"), or such committee as is appointed by the Covance Board of Directors, to administer the 2007 EEPP, to grant awards to employees and consultants of Covance or entities in which Covance has a controlling or significant equity interest. The 2007 EEPP authorizes the Compensation Committee to grant the following awards to eligible employees: options to purchase common stock; stock appreciation rights; and other stock awards either singly or in combination. The exercise period for stock options granted under the 2007 EEPP is determined by the Compensation Committee at the time of grant, and is generally ten years from the date of grant. The vesting period for stock options and stock awards granted under the 2007 EEPP is determined by the Compensation Committee at the time of grant. Generally, options vest over a three year period for senior executives and over a two year period for all other optionees. Stock awards generally vest over a three year period for all employees. The number of shares of Covance common stock initially available for grant under the 2007 EEPP totaled approximately 1.6 million plus approximately 3.3 million shares remaining available under the 2002 EEPP at the time the 2007 EEPP was approved. All stock option grants under the 2002 EEPP remaining outstanding are now administered in accordance with the provisions of the 2002 EEPP out of shares issuable under the 2007 EEPP. The Company issues authorized but previously unissued shares when options are exercised or for stock awards. At December 31, 2007 there were approximately 4.9 million shares remaining available for option grants or awards under the 2007 EEPP, up to 1.8 million of which are available for issuance as stock awards. There have been no grants of stock appreciation rights or grants to consultants of Covance or entities in which Covance has a controlling or significant equity interest under the 2002 ESOP, the 2002 EEPP or the 2007 EEPP.

Effective January 1, 2006, the Company adopted the fair value recognition provisions of SFAS 123R using the modified prospective transition method. SFAS 123R revised SFAS 123, superseded APB 25 and amended Statement of Financial Accounting Standards No. 95, Statement of Cash Flows. Under the modified prospective transition method, compensation expense is recognized in the financial statements on a prospective basis for (a) all share-based payments granted prior to, but not vested as of January 1, 2006, based upon the grant-date fair value estimated in accordance with the original provisions of SFAS 123, and (b) share-based payments granted on or subsequent to January 1, 2006, based upon the grant-date fair value estimated in accordance with the provisions of SFAS 123R. The grant-date fair value of awards expected to vest is expensed on a straight-line basis over the vesting period of the related awards. Under the modified prospective transition method, results for prior periods are not restated.

Results of operations for the year ended December 31, 2007 include $21.9 million ($14.7 million net of tax benefit of $7.2 million) of total stock-based compensation expense, $7.5 million of which has been included in cost of revenue and $14.4 million of which has been included in selling, general and administrative expenses. Results of operations for the year ended December 31, 2006 include $21.5 million ($14.5 million net of tax benefit of $7.0 million) of total stock-based compensation expense, $7.0 million of which has been included in cost of revenue and $14.5 million of which has been included in selling, general and administrative expenses.

Prior to January 1, 2006, Covance followed the disclosure-only provisions of SFAS 123 and, accordingly, accounted for awards under its share based compensation plans pursuant to the recognition and measurement principles of APB 25 and related Interpretations, as permitted by SFAS 123. Under APB 25, compensation expense was recognized in the financial statements for the fair value of stock awards. However, no compensation expense was recorded in the financial statements for stock option grants, as all options have been granted with an exercise price equal to the market value of the underlying common stock on the date of grant. Additionally, no compensation expense was recorded in the financial statements for shares purchased by employees under the Company's Employee Stock Purchase Program as that plan was considered to be non-compensatory under APB 25. The following table illustrates the effect on net income and earnings per share for the year ended December 31, 2005 had Covance applied the fair value recognition provisions of SFAS 123 to all of its stock-based employee compensation plans.

Options—The grant-date fair value of stock option awards is estimated using an option pricing model. For stock options granted prior to January 1, 2006, the Company used the Black-Scholes-Merton option pricing formula to estimate the grant-date fair value of such awards. For stock options granted on or subsequent to January 1, 2006, the Company is using the Lattice-Binomial option pricing formula to estimate the grant-date fair value of stock option awards. The Company changed to the Lattice-Binomial option pricing formula as it believes such formula may result in a better estimate of fair value than the Black-Scholes-Merton formula. In order to estimate the grant-date fair value, option pricing models require the use of estimates and assumptions as to (a) the expected term of the option, (b) the expected volatility of the price of the underlying stock, (c) the risk-free interest rate for the expected term of the option and (d) pre-vesting forfeiture rates. The expected term of the option is based upon the contractual term, taking into account expected employee exercise and expected post-vesting employment termination behavior. The expected volatility of the price of the underlying stock is based upon the historical volatility of the Company's stock computed over a period of time equal to the expected term of the option. The risk free interest rate is based upon the implied yields currently available from the U.S. Treasury zero-coupon yield curve for issues with a remaining duration equal to the expected term of the option. Pre-vesting forfeiture rates are estimated based upon past voluntary termination behavior and past option forfeitures.

The following table sets forth the weighted-average assumptions used to calculate the fair value of options granted for the years ended December 31, 2007, 2006 and 2005:



Expected stock price volatility	42%	44%	44%
Risk free interest rate(s)	4.7% - 5.1%	3.9% - 4.5%	3.7%
Expected life of options (years)	4.3	4.3	5.0

The weighted-average grant-date fair value per share of options granted during 2007, 2006 and 2005 were $24.40, $22.00 and $18.14, respectively. As of December 31, 2007, the total unrecognized compensation cost related to non-vested stock options granted was $5.7 million and is expected to be recognized over a weighted average period of 1.4 years.

Cash proceeds from stock options exercised during the years ended December 31, 2007, 2006 and 2005 totaled $22.2 million, $28.4 million and $28.8 million, respectively. Prior to the adoption of SFAS 123R, the Company presented the tax benefit of deductions resulting from the exercise of stock options as an operating cash flow in the Statements of Cash Flows in accordance with SFAS 123 and APB 25. For the year ended December 31, 2005, the tax benefit realized and included in operating cash flows totaled $11.7 million. SFAS 123R requires that the cash flows resulting from tax benefits realized on tax deductions "in excess of" the compensation expense recognized (either in the financial statements or the pro forma footnote disclosures) for stock options exercised in the period be classified as a financing cash flow. The "excess tax benefit" classified as a financing cash inflow during the years ended December 31, 2007 and 2006 were $6.0 million and $7.4 million, respectively, and would have been classified as an operating cash inflow under SFAS 123. The actual tax benefit realized on stock options exercised during the years ended December 31, 2007 and 2006 were $9.2 million and $12.8 million, respectively. The difference between the actual tax benefit received and the "excess tax benefit" computed in accordance with SFAS 123R for the years ended December 31, 2007 and 2006, of $3.2 million and $5.4 million, respectively, continues to be classified as an operating cash inflow.

Restricted Stock Awards—Restricted stock awards are granted subject to certain restrictions, including in some cases service conditions (restricted stock) and in other cases service and performance conditions (performance-based shares). The grant-date fair value of restricted stock and performance-based share awards, which has been determined based upon the market value of Covance's shares on the grant date, is expensed over the vesting period.

The following table sets forth Covance's performance-based shares and restricted stock activity as of and for the year ended December 31, 2007:

As of December 31, 2007, the total unrecognized compensation cost related to non-vested performance-based shares and restricted stock awards was $19.9 million. This cost is expected to be recognized over a weighted average period of 1.8 years.

restricted stock awards which vested during 2007, 2006 and 2005 was $3.4 million, $0.1 million and $1.3 million, respectively.

Employee Stock Purchase Plan—Covance also has an employee stock purchase plan (the "ESPP") pursuant to which Covance may make available for sale to employees shares of its common stock at a price equal to 85% of the lower of the market value on the first or last day of each calendar quarter. The ESPP, administered by the Compensation Committee, is intended to give Covance employees the opportunity to purchase shares of Covance common stock through payroll deductions. A maximum of 3.0 million shares may be purchased by Covance employees under the ESPP. During 2007, 2006 and 2005, a total of 99,441 shares, 92,927 shares and 102,501 shares of common stock, respectively, were issued under the ESPP. At December 31, 2007, there were approximately 0.8 million shares remaining for purchase under the ESPP.

11. Commitments and Contingencies

Minimum annual rental commitments under non-cancelable operating leases, primarily for its offices and laboratory facilities, in effect at December 31, 2007 are as follows:

Year Ending December 31,

Operating lease rental expense aggregated $28.4 million, $27.0 million and $24.8 million for 2007, 2006 and 2005, respectively.

12. Segment Information

Covance has two reportable segments: early development and late-stage development. Early development services, which includes Covance's preclinical and clinical pharmacology service capabilities, involve evaluating a new compound for safety and early effectiveness as well as evaluating the absorption, distribution, metabolism and excretion of the compound in the human body. It is at this stage that a pharmaceutical company, based on available data, will generally decide whether to continue further development of a drug. Late-stage development services, which include Covance's central laboratory, clinical development, periapproval and market access services, are geared toward demonstrating the clinical effectiveness of a compound in treating certain diseases or conditions, obtaining regulatory approval and maximizing the drug's commercial potential. The accounting policies of the reportable segments are the same as those described in Note 2.
