Overview

        We are a leading global provider of solutions that accelerate the drug discovery and development process, including research models and associated services, and outsourced preclinical services. As the drug development process continues to require the steadily increasing investment of time and money—various studies and reports estimate it takes between 10-15 years, between $800 million and $1 billion, and exploration of more than 10,000 drug compounds to produce a single FDA approved drug—Charles River is in the position of being able to leverage our expertise in an efficient and cost-effective way to aid our customers in bringing their drugs to market faster.

        We currently have two reporting segments: Research Models and Services (RMS) and Preclinical Services (PCS) (which includes Phase I clinical services). We provide the animal research models required in research and development of new drugs, devices and therapies and have been in this business for 60 years. We have built upon our core competency of laboratory animal medicine and science (research model technologies) to develop a diverse and growing portfolio of products and services. Our wide array of tools and services enables our customers to reduce costs, increase speed and enhance their productivity and effectiveness in drug discovery and development. Our customer base includes global pharmaceutical companies, a wide range of biotechnology companies, as well as government agencies, leading hospitals and academic institutions around the world. We currently operate approximately 60 facilities, including our production and warehousing facilities, in 15 countries worldwide. Our products and services, supported by our global infrastructure and deep scientific expertise, enable our customers to meet many of the challenges of early-stage life sciences research. In 2007, our net sales from continuing operations were $1.23 billion and our operating income from continuing operations was $227.2 million.

        In recent years, we have completed a number of acquisitions, primarily involving our PCS business, that broadened our present portfolio of high-end services to include general toxicology, specialty toxicology and Phase I clinical services. In addition, these acquisitions:


        These acquisitions have been critical in our continuing mission to support our key pharmaceutical and biotechnology customers, who are increasingly seeking full service, global partners to whom they can outsource more of their preclinical research and development efforts. By some estimates, the outsourced drug development services markets in which we participate (exclusive of research models and associated services, but including preclinical and Phase I clinical services) is in excess of $4.6 billion annually. It is thought that this represents only 20-25% of all of the drug development work currently performed, and is expected to increase over time as outsourcing trends continue.

        In 2007, much of our focus has been dedicated towards positioning ourselves to take advantage of long-term opportunities to support our clients as they increasingly outsource drug development services, as evidenced by our capacity expansion program. The current program to replace our existing PCS facilities in Massachusetts and Nevada with new, state-of-the-art facilities has been underway for two

2



years and, in 2007, we opened the first of those sites in Massachusetts. We plan to open the new preclinical site in Nevada on schedule in 2008, followed by additional preclinical capacity in Canada, Scotland, and Ohio in 2009. We have commenced construction of a new facility in China, due to open in late 2008, which we hope will enable us to be the partner of choice for our global pharmaceutical customers as they establish and expand research and development activities in China. In addition, in 2007 we expanded capacity in our California RMS facility and broke ground on a new RMS facility in Maryland. The Maryland facility is being constructed in part to support the 10-year agreement with the National Cancer Institute to manage its research model colonies. This agreement is the first of its kind where the colonies will be managed in Charles River's facilities under a Charles River Dedicated Resources™ agreement, or CRDR™. These flexible partnering arrangements, which are generally for multiple years and involve financial commitments, are tailored to individual client's requirements and are used in both the RMS and PCS business segments.

        Research Models and Services (RMS).    Charles River has been supplying research models to the drug development industry since 1947. With approximately 150 different strains, we continue to maintain our position as the global leader in the production and sale of research models, principally genetically and virally defined purpose-bred rats and mice. We also provide a variety of related services that are designed to assist our customers in supporting the use of research models in drug development. With multiple facilities located on three continents (North America, Europe and Asia (Japan)), we maintain production centers, including a total of approximately 170 barrier rooms or isolator facilities strategically located near our customers. In 2007, RMS accounted for 47% of our total net sales and approximately 41% of our employees including approximately 130 science professionals with advanced scientific degrees.

        Our RMS segment is comprised of (1) Research Models, (2) Research Model Services and (3) other related products and services.

        Research Models.    A significant portion of this business is comprised of the commercial production and sale of research models, principally purpose-bred rats, mice and other rodents for use by researchers. We provide our rodent models to numerous customers around the world, including most pharmaceutical companies, a broad range of biotechnology companies, many government agencies, and leading hospitals and academic institutions. Our research models include both standard strains and disease models such as those with compromised immune systems, which are increasingly in demand as early-stage research tools. The United States Food and Drug Administration (FDA) and foreign regulatory bodies typically require the safety and efficacy of new drug candidates be tested on research models like ours prior to testing in humans. As a result, our research models are an essential part of the drug discovery and development process.

        Our rodent species have been and continue to be some of the most extensively used research models in the world, largely as a result of our continuous commitment to innovation and quality in the breeding process. Our research models are bred and maintained in controlled environments which are designed to ensure that the animals are free of specific viral and bacterial agents and other contaminants that can disrupt research operations and distort results. With our barrier room production capabilities, we are able to deliver consistently high-quality research models worldwide.

        Our small research models include:

3



        We also offer new and proprietary, disease-specific rat models used to find new treatments for diseases such as diabetes, obesity and cardiovascular and kidney disease. We are presently focusing our disease model program on four areas of research: cardiovascular, metabolic, renal and oncology which, in addition to providing overlapping disease modalities that support multiple uses of certain models, also permits us to concentrate on focused sales and marketing efforts.

        We believe that over the next several years, many new genetically engineered models will be developed and used in biomedical research, such as models with modified genetic material, knock-out models with one or more disabled genes, and transgenic models that incorporate or exclude a particular gene. These more highly defined and characterized models will allow researchers to further focus their investigations into disease conditions and potential new therapies or interventions. We intend to build upon our position as a leader in this field to expand our presence in this market for higher-value research models.

        In addition to our small research models, we also are a premier provider of high-quality purpose-bred, specific pathogen-free (SPF) or disease free, large research models to the biomedical research community, principally for use in their drug development and testing studies.

        Research Model Services.    RMS also offers a variety of services, described below, designed to assist our customers in screening drug candidates faster, including those which are related to genetically defined research models for in-house research, as well as those services designed to implement efficacy screening protocols to improve the customer's drug evaluation process. These services address the need among pharmaceutical and biotechnology companies to outsource the non-core aspects of their drug discovery activities. These services capitalize on the technologies and relationships developed through our research model business. We currently offer four major categories of research models services—transgenic services, research animal diagnostics, consulting and staffing services, and discovery services.

        Transgenic Services.    In this area of our business, we assist our customers in validating, maintaining, improving, breeding and testing research models purchased or created by our customers for biomedical research activities. While the creation of a transgenic model can be a critical scientific event, it is only the first step in the discovery process. Productive utilization of genetically engineered research models requires significant additional technical expertise. We provide breeding expertise, model characterization (including genotyping and phenotyping) and colony development, quarantine, embryo cryopreservation, embryo transfer and health and genetic monitoring. We provide these services to over 200 laboratories around the world from pharmaceutical and biotechnology companies to hospitals and universities and maintain more than 1,000 different types of naturally occurring or experimentally manipulated research models for our customers.

        Research animal diagnostics.    We assist our customers in monitoring and analyzing the health and genetics of the research models used in their research protocols. We developed this capability internally by building upon the scientific foundation created by the diagnostic laboratory needs of our research model business. Depending upon a customer's needs, we may serve as its sole-source testing laboratory, or as an alternative source supporting its internal laboratory capabilities. We believe that the continued growth in model development and characterization and utilization of specific disease models and genetically engineered models will drive our future growth as the reference laboratory of choice for health and genetic testing of laboratory animals.

        Discovery Services.    Augmenting our traditional model production and transgenic services described above, we believe there are emerging opportunities to assist our customers in speeding the development process by providing services that prepare models to be used in studies immediately upon arrival at the customer's facility, rather than requiring time and effort on the part of the customer to prepare the models. As a result of our veterinary medicine expertise, we are well positioned to provide

4



such services, which include surgical procedures, feeding and aging, and biological and chemical modification.

        Consulting and Staffing Services.    Building upon our core capability as the leading provider of high-quality research models, we manage animal care operations (including recruitment, training, staffing and management services) on behalf of government and academic organizations, as well as commercial customers. Demand for our services results from the growing trend by these large institutions to outsource internal functions or activities that are not critical to the core scientific innovation process, or for which they do not maintain the necessary resources in-house. In addition, we believe that our expertise in animal care and facility operations enhances the productivity and quality of our customers' animal care and use programs.

        Other Related Research Model Products and Services.    We also offer two other categories of products and services within RMS—vaccine support and in vitro technology products.

        Vaccine Support.    We are the global leader for the supply of specific pathogen-free, or SPF, chickens and fertile chicken eggs. SPF chicken embryos are used by animal health companies as self-contained "bioreactors" for the manufacture of live viruses. These viruses are used as a raw material primarily in poultry, as well as human vaccine, applications. The production of SPF eggs is done under biosecure conditions, similar in many ways to our research model production. We have a worldwide presence that includes several SPF egg production facilities in the United States, a joint venture in Mexico and contracted production capabilities in Hungary. We also operate a specialized avian laboratory in the United States, which provides in-house testing and support services to our customers and produces poultry diagnostics.

        In Vitro Technology.    Our in vitro business provides non-animal, or in vitro, methods for lot release testing of medical devices and injectable drugs for endotoxin contamination. We are committed to being the leader in providing our customers with in vitro alternatives as these methods become scientifically validated and commercially feasible, and toward that goal we work with and support the European Center for Validation of Alternative Methods in these efforts. Endotoxin testing uses a processed extract from the blood of the horseshoe crab, known as limulus amebocyte lysate (LAL). The LAL test is the first and only major FDA-validated in vitro alternative to an animal model test for endotoxin detection in pharmaceutical and medical device manufacturing. The process of extracting blood is generally not harmful to the crabs, which are subsequently returned to their natural ocean environment. Our in vitro technology business produces and distributes endotoxin testing kits, reagents, software, accessories, instruments and associated services to pharmaceutical and biotechnology companies worldwide. We are a market leader in endotoxin testing, which is used for FDA-required quality control testing of injectable drugs and medical devices, their components and the processes by which they are manufactured.

        We have developed the next generation of the endotoxin testing platform, known as the Endosafe Portable Testing System (Endosafe®-PTS). The PTS is a portable endotoxin testing platform which allows endotoxin testing in the field, affording researchers accurate and timely results. In 2006, we received FDA approval for the sale and marketing of the PTS system for FDA-required lot release endotoxin testing. The PTS can also be used for non-regulated applications, ranging from drug research and development to environmental monitoring. As an example, a modified version of the PTS was launched into space aboard the space shuttle Discovery and reached the International Space Station as part of NASA's ongoing efforts to conduct biological research in space. The PTS system has recently expanded into markets such as cell transplant and dialysis clinics, and, especially, nuclear pharmacies, where PTS is being adopted for lot release testing of nuclear medicines in response to pending FDA regulations. We are anticipating other opportunities developing as our customers react to the FDA's Process Analytical Technology (PAT) Initiative. In addition, over the next few years we look towards exploring other applications such as the environmental contaminant markets (pesticides and hazardous materials) and clinical diagnostics (infectious disease at point of care).

        Our PCS customers are principally engaged in the discovery and development of new drugs, devices and therapies.

        The development services portion of our PCS business enables our customers to outsource their critical, regulatory-required drug and toxicology disposition activities to us. The demand for these services was historically driven by preclinical development programs of biotechnology companies, which traditionally have been outsourced, and also by the selective outsourcing strategy of larger global pharmaceutical companies. The necessary significant investments in personnel, facilities and other capital resources required in order to efficiently conduct and perform these activities means that global pharmaceutical companies and biotechnology companies are frequently choosing to outsource their development activities, allowing them to focus on their core competencies of innovation and early drug discovery (for biotechnology companies) and promotion and market distribution (for pharmaceutical companies). Large pharmaceutical companies, in particular, are increasingly closing facilities and reducing staff, thus we believe the demand for our preclinical service offerings will continue to strengthen.

        We are one of the two largest providers of preclinical services worldwide and offer particular expertise in the design, execution and reporting of general and specialty toxicology studies, especially those dealing with innovative therapies and biologicals. We currently provide preclinical services at multiple facilities located in the United States, Canada and Europe, and are anticipating being able to offer expanded PCS services in China in the second half of 2008. As a result of increasing demand for outsourced preclinical services, we have recently conducted or are presently conducting significant facilities expansions at our preclinical facilities—one in Massachusetts which opened in 2007 and another in Nevada which opened in early 2008, as well as expansions at our Canada, Ohio, Pennsylvania (biopharmaceutical services) and Scotland PCS facilities. The Massachusetts and Nevada facilities, when fully built out, will more than double the size of the pre-existing operations. Our PCS segment represented 53% of our total net sales in 2007 and employed 56% of our employees including approximately 450 science professionals with advanced scientific degrees.

        We currently offer the following preclinical services, in which we include both in vivo and in vitro studies, supportive laboratory services, and strategic preclinical consulting and program management to support product development from inception to proof of concept.

6


        Toxicology.    Toxicology is one of our core preclinical competencies and a competitive strength. Once a lead molecule is selected, the stage of preclinical development begins where appropriate toxicology studies are conducted to support initial clinical trials. These studies are performed on animal models to understand the toxic effects that a compound has on an organism over a variety of doses and over various time periods, and focus on safety and potential harmful effects. Our toxicology services feature:

Our toxicology facilities operate in compliance with Good Laboratory Practices (GLPs) as required by the FDA as well as other international regulatory bodies. Our facilities are regularly inspected by U.S. and other GLP compliance monitoring authorities, as well as our own and our customers' Quality Assurance departments.

        Pathology Services.    In the drug development process, the ability to identify and characterize clinical and anatomic pathologic change is critical in determining the safety of a new compound. We employ a large number of highly trained pathologists who use state-of-the-art techniques to identify potential compound-related changes within tissues, fluids and cells, as well as at the molecular level. Pathology support is critical for regulatory driven safety studies, but also for specialized investigative studies, discovery support, and stand-alone immunohistochemistry evaluations for monoclonal antibodies. Key "go/no-go" decisions regarding continued product development are typically dependent on the identification, characterization and evaluation of gross and microscopic pathology findings we perform for our clients.

        Bioanalysis, Pharmacokinetics, and Drug Metabolism.    In support of preclinical drug safety testing, our customers are required to demonstrate ample drug exposure, stability in the collected sample, kinetics of their drug or compound in circulation, the presence of metabolites, and with recombinant proteins and peptides, the presence of anti-drug antibodies. We have scientific depth in the sophisticated analytical techniques required to satisfy these requirements for a number of drug classes (including oligonucleotide and inhibitory RNAs). In the event that the sample analysis for preclinical study support translates to opportunities to analyze clinical samples for the same drug once human testing begins, we have opportunities to capture the benefits of bridging preclinical bioanalysis with later clinical development. Once the analysis is complete, our scientists evaluate the data to provide information on the pharmacokinetics and/or toxicokinetics of the exposure to the drug, as well as

7



complete evaluation of the distribution of the drug or metabolites by radio-labeled techniques. Pharmacokinetics refers to understanding what the body does to a drug or compound once administered, including the process by which the drug is absorbed, distributed in the body, metabolized, and excreted (ADME); toxicokinetics refers to the same understanding as applied to potential toxic substances. Our clients require these studies for the full preclinical assessment of the disposition of the drug the results of which are used in the final preclinical safety evaluation of the compound.

        Discovery Support.    At the earliest stages of lead compound identification, our scientists are engaged in evaluating the activity and efficacy of drug candidates in several important therapeutic areas, including:

We also offer lead optimization strategies including early pharmacokinetic, metabolism, and toxicology support to help in early integrative drug selection criteria.

        We provide specialized testing, characterization and small scale manufacturing services that are frequently outsourced by global pharmaceutical and biotechnology developers. We also consult with customers on process development, validation, manufacturing scale-up and biological testing. We also grow, store and characterize client cell lines for later development and manufacture of therapeutic proteins.

        Biopharmaceutical testing and characterization services allow customers to confirm that biologically produced drug candidates are correctly identified and stable and are produced consistently and essentially contaminant free. This testing is required by the FDA and other global regulatory authorities to obtain new drug approval, maintain a government licensed manufacturing facility and release approved therapeutic products for use in patients.

        Phase I clinical trials are usually short duration studies conducted on a small number (20-100) of healthy human subjects (although special populations can be used) under highly controlled conditions. Testing is usually performed where trial participants can be closely monitored in a secure environment, such as at a clinic-type facility or hospital.

        Our clinical services capabilities encompass two premier, internationally recognized Phase I clinics—one in Europe (Edinburgh, Scotland) and the other in North America (Tacoma, Washington), with a combined capacity of over 300 beds. We focus our clinical services business on high-end clinical pharmacology studies in healthy participants. From a strategic perspective, we believe that our clinical services business benefits from pull-through from our preclinical and laboratory services (particularly with our biotechnology customers). Correspondingly, our preclinical and laboratory services businesses benefit from the presence of our Phase I clinical offerings as we can take advantage of enhanced economies of scale as well as "pull-down" from existing clinical customers.

        We offer a wide range of Phase I clinical research services designed to move lead pharmaceutical candidates rapidly from preclinical development through Phase I pharmacokinetic tolerability and pharmacodynamic assessment to explore human pharmacology. We can conduct studies across a wide

8



range of therapeutic areas, and have demonstrated experience in complex dose tolerance, radio-labeled, pharmacokinetics, pharmacodynamics and bioavailability studies. In addition, we provide customers with high-end "first-in-human" studies for novel compounds, and expertise in complex drug-drug interaction studies. Participants at both clinics are evaluated through an intensive screening process to ensure study suitability. We employ clinical regulatory compliance staff at these facilities to monitor the conduct and reporting of Phase I trials and to assure management that these trials are conducted in compliance with appropriate regulatory requirements.

Our Strategy

        Our objective is to be the preferred strategic global partner for our clients in accelerating the search for drugs, devices and therapies. From discovery through proof of concept, our goal is to provide products and services for drug discovery and development, which are almost universally mandated by law. Our business is primarily driven by the continued growth of research and development spending by pharmaceutical and biotechnology companies, the federal government and academic institutions and of outsourced services. According to reports by the Biomedical Industry Advisory Group, it takes 11 to 16 years and costs in the range of $180 million to $1.65 billion, with an average cost of approximately $900 million, to bring a new drug to market. Similarly, a separate 2007 report by the Pharmaceutical Research and Manufacturers of America estimate that it takes 10 to 15 years and costs in excess of $800 million to develop a drug ($1.2 billion for a biologic).

        As the pressure to develop a strong pipeline of innovative new drugs increases, so does the pressure to contain costs, to implement research in multiple countries simultaneously and to identify, hire and retain a breadth of scientific and technical experts. In order to facilitate and speed their research (as well as to convert largely fixed costs into variable expenses), our pharmaceutical and biotechnology customers are increasingly making strategic decisions to outsource services which can be provided by high-quality service providers like us. For instance, many of our larger customers—particularly those in the pharmaceutical industry—have announced plans to rationalize their workforce and facilities and/or increase outsourcing in order to concentrate on their core businesses and new product research and identification. In the past year, we believe that the increase in these actions and the necessary growth of outsourcing is being driven by a unique confluence of events, including:

        Outsourcing allows our customers to concentrate their internal expertise and resources on early drug discovery, while continuing to advance their most promising products through the development pipeline. This creates opportunities for companies such as ours that can help optimize our clients' programs and assist in accelerating the drug discovery and development process. Our strategy is to capitalize on these opportunities by continuing to build our portfolio of premium, value-added products

9



and services through internal development and investment, augmented by strategic "bolt-on" transactions.

        In today's business environment, we believe there is a particular advantage in being a large, global, high-quality provider of services throughout the drug discovery and development continuum. Many of our customers, especially large pharmaceutical companies, are attracted to Tier 1 contract research organizations with a full breadth of capabilities, and choose to establish preferred provider relationships with only a small number. We are focused on being recognized as a premier preferred provider and maintaining long-term strategic partnerships with our customers. Accordingly, with many of our largest customers, we have entered into global provider agreements that span both segments of our business.

        Furthermore, in response to our clients' requests that we provide increased yet flexible services specifically designed for their individual needs, we have expanded our commitment and focus to develop Charles River Dedicated Resources (CRDR) arrangements. CRDRs are broad-based multi-year partnering arrangements, generally involving financial commitments from the customer, which tap into the broad array of physical and/or service resources that we provide. Examples of the type of accommodations we can provide in CRDRs include dedicated space within existing facilities, building out space to a particular specification, or even establishing a new facility. These CRDRs represent a meaningful, and we expect growing, percentage of our business.

        We intend to continue to broaden the scope of our products and services primarily through internal development, which will be augmented, as needed, through focused acquisitions and alliances. Our approach to acquisitions is a disciplined one that seeks to target businesses that are a sound strategic fit and that offer the prospect of enhancing stockholder value. This strategy may include geographic expansion of existing core services, strengthening of one of our core services or the addition of a new product or service in a related or adjacent business.

        We believe that we are well positioned to exploit both existing and new outsourcing opportunities. As strategic outsourcing by our customers increases, we believe that our expertise in areas previously addressed by our customers' in-house capabilities allows us to provide a more flexible, efficient and cost-effective alternative for them. In short, because these products and services are the core of our business, we are able to build and maintain expertise and tap into economies of scale that are difficult for our customers to match with their internal capabilities.

        We intend to focus our marketing efforts on, among other things, stimulating demand for further outsourcing. As a result of these efforts, we expect to be better positioned to gain additional market share to take advantage of promising opportunities which are available to us as a result of this continuing trend, as well as broader based collaboration across the in vivo discovery to first-in-human continuum. In 2007 we invested heavily in expanding our facilities capacity, and we intend to continue the capital expansion activity in 2008. Similarly, we are investing in our information technology systems and resources in order to better serve our customers, harmonize our data, and streamline our processes.

Customers

        Our customers continue to consist primarily of all of the major pharmaceutical companies, many biotechnology companies, animal health, medical device, diagnostic and other life sciences companies, and leading hospitals, academic institutions, and government agencies. We have stable, long-term relationships with many of our customers. During 2007, no single commercial customer accounted for more than 6% of our total net sales.

        For information regarding net sales and long-lived assets attributable to both of our business segments for the last three fiscal years, please see Note 12 included in the Notes to Consolidated Financial Statements included elsewhere in this Form 10-K. For information regarding net sales and long-lived assets attributable to operations in the United States, Europe, Canada, Japan and other

10



countries for each of the last three fiscal years, please review Note 12 included in the Notes to Consolidated Financial Statements included elsewhere in this Form 10-K.

Sales, Marketing and Customer Support

        We sell our products and services principally through our direct sales force and account management teams, the majority of whom work in North America, with the balance in Europe and Japan. Our primary promotional activities include organizing scientific symposia, publishing scientific papers, making presentations and participating at scientific conferences and trade shows in North America, Europe and Japan. We supplement these scientifically based marketing activities with trade advertising, direct mail, newsletters and are currently developing a new website for launch in 2008. The direct sales force is supplemented by international distributors for our products, particularly with respect to our In Vitro technology business.

        Our internal marketing/product management teams support the field sales staff and account management teams while developing and implementing programs to create close working relationships with customers in the biomedical research industry. We maintain client/customer service, technical assistance and consulting service departments, which address both our customers' routine and more specialized needs. We frequently assist our customers in solving problems related to animal husbandry, health and genetics, biosecurity, preclinical and clinical study design, regulatory consulting, protocol development and other areas in which our expertise is widely recognized as a valuable resource by our customers.

Competition

        Our strategy is to be a leader in each of the markets in which we participate. We compete in the marketplace on the basis of quality, reputation, responsiveness, pricing, innovation, breadth of therapeutic and scientific expertise, timeliness and availability, supported by our professional bench strength in animal science and toxicology, global capabilities and strategically located facilities worldwide. We are able to offer a unique portfolio through our broad array of both routine and specialized preclinical services, as well as a wide range of research models and research model services.

        The competitive landscape for our two business segments varies.

        We believe that the barriers to entry in certain of our business units, particularly those which require substantial capital expenditures and mandate GLP compliant practices, are generally high and present a significant impediment for new market participants.

Industry Support and Animal Welfare

        One of our core values is a concern for and commitment to animal welfare. We have been in the forefront of animal welfare improvements in our industry, and continue to show our commitment with special recognition programs for employees who demonstrate an extraordinary commitment in this critical area of our business. We created our own Humane Care Initiative, which is directed by our Animal Welfare and Training Group. The goal of the initiative is to assure that we continue as a worldwide leader in the humane care of laboratory animals. Laboratory animals are an important resource that further our knowledge of living systems and contribute to the discovery of life-saving drugs and procedures. We work hand-in-hand with the scientific community to understand how living conditions, handling procedures and stress play an important role in the quality and efficiency of research. As animal caregivers and researchers, we are responsible to our clients and the public for the health and well being of the animals in our care.

        We support a wide variety of organizations and individuals working to further animal welfare as well as the interests of the biomedical research community. We fund scholarships to laboratory animal training programs, provide financial support to non-profit institutions that educate the public about the benefits of animal research and provide awards and prizes to outstanding leaders in the laboratory animal medicine field.

Employees

        As of December 29, 2007, we had approximately 8,500 employees including approximately 600 science professionals with advanced degrees, including approximately 140 D.V.M.s, 240 Ph.D.s and 20 M.D.s. Our employees are not unionized in the United States, although employees are unionized at some of our European facilities, consistent with local customs for our industry. Our annual satisfaction surveys indicate that we have an excellent relationship with our employees.

Backlog

        Our backlog for our PCS business segment was approximately $393 million at December 29, 2007. We do not report backlog for the RMS segment because turnaround time from order placement to fulfillment, both for products and services, is rapid. Our preclinical services are performed over varying durations, from short to extended periods of time, which may be as long as several years. We maintain an order backlog to track anticipated revenue from studies and projects that either have not started, but are anticipated to begin in the near future, or are in process and have not been completed. We only recognize a study or project in backlog after we have received written evidence of a customer's intention to proceed. We do not recognize verbal orders. Cancelled studies or projects are removed from backlog.

        We believe our aggregate backlog as of any date is not necessarily a meaningful indicator of our future results for a variety of reasons. First, studies vary in duration (i.e., some studies that are included in 2007 backlog may be completed in 2008, while others may be completed in later years). Second, the scope of studies may change, which may either increase or decrease their value. Third, studies included in backlog may be subject to bonus or penalty payments. Fourth, studies may be terminated or delayed at any time by the client or regulatory authorities for a number of reasons, including the failure of a drug to satisfy safety and efficacy requirements or a sponsor making a strategic decision that a study or service is no longer necessary. Delayed contracts remain in our backlog until a determination of whether to continue, modify or cancel the study has been made. 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 to be filled in the current year.

12


Regulatory Matters

        As our business operates in a number of distinct operating environments and in a variety of locations worldwide, we are subject to numerous, and sometimes overlapping, regulatory environments, as described below.

        The Animal Welfare Act (AWA) governs the care and use of certain species of animals used for research. The United States Congress has passed legislation which excludes laboratory rats, mice and chickens used for research from regulation under the AWA. As a result, most of our United States small animal research model activities and our vaccine support services operations are not subject to regulation under the AWA. For regulated species, the AWA and attendant Animal Care regulations require producers and users of regulated species to provide veterinary care and to utilize specific husbandry practices such as cage size, shipping conditions, sanitation and environmental enrichment to assure the welfare of these animals. We comply with licensing and registration requirement standards set by the United States Department of Agriculture (USDA) for the care and use of regulated species. Our animal production facilities and preclinical facilities in the U.S. are accredited by the Association for Assessment and Accreditation of Laboratory Animal Care International (AAALAC), a private, nonprofit, international organization that promotes the humane treatment of animals in science through voluntary accreditation and assessment programs. AAALAC covers all species of laboratory animals, including rats, mice and birds. Our preclinical business is also generally regulated by the USDA.

        Our import and export of animals in support of several of our business units as well as our operations in foreign countries are subject to a variety of national, regional, and local laws and regulations, which establish the standards for the humane treatment, care and handling of animals by dealers and research facilities. We maintain the necessary certificates, licenses, detailed standard operating procedures and other documentation required to comply with applicable regulations for the humane treatment of the animals in our custody at our locations.

        Our PCS business conducts nonclinical laboratory safety studies intended to support the registration or licensing of our clients' products throughout the world. The conduct of these studies must comply with national statutory or regulatory requirements for Good Laboratory Practice (GLP). GLP regulations describe a quality system concerned with the organizational process and the conditions under which nonclinical laboratory studies are planned, performed, monitored, recorded, archived and reported. GLP compliance is required by such regulatory agencies as the FDA, United States Environmental Protection Agency, European Agency for the Evaluation of Medicinal Products, Medicines and Healthcare Products Regulatory Agency (MHRA) in the United Kingdom, Health Canada, and the Japanese Ministry of Health and Welfare. GLP requirements are significantly harmonized throughout the world and our laboratories are capable of conducting studies in compliance with all appropriate requirements. To assure our compliance obligations, we have established quality assurance units (QAU) in each of our nonclinical laboratories. The QAUs operate independently from those individuals that direct and conduct studies and monitor each study to assure management that the facilities, equipment, personnel, methods, practices, records, and controls are in compliance with GLP. Our laboratory managers use the results of QAU monitoring as part of a continuous process improvement program to assure our nonclinical studies meet client and regulatory expectations for quality and integrity.

        Our PCS business also conducts human Phase I clinical trials and provides services in support of our clients' registration or licensing applications. Human clinical trials are conducted in a progressive fashion beginning with Phase I, and in the case of approved drugs, continued through Phase IV trials. Phase I studies are the initial human clinical trials and are conducted with a small number of subjects under highly controlled conditions. These clinical trials and services are performed in accordance with the International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use Good Clinical Practice Consolidated Guidance and in compliance with regulations governing the conduct of clinical investigations and the protection of human clinical trial subjects. In the United States, these trials and services must comply with FDA regulations and in

13



Europe our clinical trials and services must comply with the clinical trials directive of the European Union. Neither FDA regulations nor the clinical trials directive requires a quality assurance program; however, each of our Phase I facilities has an established quality assurance unit that monitors the conduct and reporting of Phase I trials to assure that these trials are conducted in compliance with appropriate regulatory requirements.

        Our manufacturing business produces endotoxin test kits and reagents and vaccine support products. Additionally, the analytical divisions of several of our nonclinical laboratories conduct stability and potency testing in support of our clients' manufacturing programs. These activities are subject to regulation by the FDA and MHRA under their respective Good Manufacturing Practice regulations or the FDA's Quality Systems Regulation (manufacturing of medical devices). We are required to register with the FDA as a device manufacturer and are subject to inspection on a routine basis for compliance with these regulations. These regulations require that we manufacture our products in a prescribed manner with respect to, and maintain records of, our manufacturing, testing and control activities.

        All of our sites are also subject to licensing and regulation under national, regional and local laws relating to the surface and air transportation of laboratory specimens, the handling, storage and disposal of laboratory specimens, hazardous waste and radioactive materials, and the safety and health of laboratory employees. Although we believe we are currently in compliance in all material respects with such national, regional and local laws (which include the USDA, the standards set by the International Air Transport Association, and European oversight agencies), failure to comply could subject us to denial of the right to conduct business, fines, criminal penalties and other enforcement actions.

        To ensure that all business sectors comply with applicable statutory and regulatory requirements and satisfy our client expectations for quality, we have established a corporate regulatory affairs and compliance organization that oversees our corporate quality system and all quality assurance functions within the Company. This organization reports to our Corporate Vice President for Regulatory Affairs and Compliance.

Corporate Governance

        We are committed to operating our business with integrity and accountability. We strive to meet or exceed all of the corporate governance standards established by the New York Stock Exchange, the Securities and Exchange Commission, and the Federal government as implemented by the Sarbanes-Oxley Act of 2002. Eight of the nine members of our Board of Directors are independent and have no significant financial, business or personal ties to the Company or management and all of our Board committees are composed of independent directors. The Board adheres to Corporate Governance Guidelines and a Code of Business Conduct and Ethics which has been communicated to employees and posted on our website. We are diligent in complying with established accounting principles and are committed to providing financial information that is transparent, timely and accurate. We have implemented a Related Person Transactions Policy in order to promote the timely identification of such transactions and to ensure we give appropriate consideration to any real or perceived conflicts in our commercial arrangements. We have established global processes through which employees, either directly or anonymously, can notify management (and the Audit Committee of the Board of Directors) of alleged accounting and auditing concerns or violations including fraud. Our internal Disclosure Committee meets regularly and operates pursuant to formal disclosure procedures and guidelines which help to ensure that our public disclosures are accurate and timely. Copies of our Corporate Governance Guidelines, Code of Business Conduct and Ethics and Related Person Transactions Policy are available on our website at www.criver.com under the "Investor Relations—Corporate Governance" caption.

Item 1A.    Risk Factors

Risks Related to Our Business and Industry

        Set forth below and elsewhere in this Form 10-K and in other documents we file with the SEC are risks and uncertainties that could cause actual results to differ materially from the results contemplated by the forward-looking statements contained in this Form 10-K. We note that factors set forth below, individually or in the aggregate, may cause our actual results to differ materially from expected and historical results. We note these factors for investors as permitted by the Private Securities Litigation Reform Act of 1995. You should understand that it is not possible to predict or identify all such factors. Consequently, you should not consider the following to be a complete discussion of all potential risks or uncertainties.

The outsourcing trend in the preclinical and clinical stages of drug discovery and development may decrease, which could slow our growth.

        Over the past several years, some areas of our businesses have grown significantly as a result of the increase in pharmaceutical and biotechnology companies outsourcing their preclinical and clinical research support activities. We believe that due to the significant investment in facilities and personnel required to support drug development, pharmaceutical and biotechnology companies look to outsource some or all of those services. By doing so, they can focus their resources on their core competency of drug discovery, while obtaining the outsourced services from a full-service provider like us. While industry analysts expect the outsourcing trend to continue for the next several years, a decrease in preclinical and/or clinical outsourcing activity could result in a diminished growth rate in the sales of one or more of our expected higher-growth areas and adversely affect our financial condition and results of operations. Furthermore, our customer contracts are generally terminable on little or no notice. Termination of a large contract or multiple contracts could adversely affect our sales and profitability. Our operations and financial results could be significantly affected by these risks.

A reduction in research and development budgets at pharmaceutical and biotechnology companies may adversely affect our business.

        Our customers include researchers at pharmaceutical and biotechnology companies. Our ability to continue to grow and win new business is dependent in large part upon the ability and willingness of the pharmaceutical and biotechnology industries to continue to spend on research and development and to outsource the products and services we provide. Fluctuations in the research and development budgets of these researchers and their organizations could have a significant effect on the demand for our products and services. Research and development budgets fluctuate due to changes in available resources, mergers of pharmaceutical and biotechnology companies, spending priorities and institutional budgetary policies. Our business could be adversely affected by any significant decrease in life sciences research and development expenditures by pharmaceutical and biotechnology companies, as well as by academic institutions, government laboratories or private foundations. Similarly, economic factors and industry trends that affect our clients in these industries, including funding for biotechnology companies generally, also affect our business.

A reduction or delay in government funding of research and development may adversely affect our business.

        A portion of net sales in our RMS segment is derived from customers at academic institutions and research laboratories whose funding is partially dependent on both the level and timing of funding from government sources, such as the U.S. National Institutes of Health (NIH) and similar domestic and international agencies. Government funding of research and development is subject to the political process, which is inherently unpredictable. Our sales may be adversely affected if our customers delay purchases as a result of uncertainties surrounding the approval of government budget proposals. Also, government proposals to reduce or eliminate budgetary deficits have sometimes included reduced allocations to the NIH and other government agencies that fund research and development activities. NIH funding has remained fairly flat in recent years and a reduction in government funding for the

15



NIH or other government research agencies could adversely affect our business and our financial results.

Changes in government regulation or in practices relating to the pharmaceutical or biotechnological industries, including potential health care reform, could decrease the need for the services we provide.

        Governmental agencies throughout the world, but particularly in the United States, strictly regulate the drug development process. Our business involves helping pharmaceutical and biotechnology companies, among others, navigate the regulatory drug approval process. Accordingly, many regulations, and often new regulations, are expected to result in higher regulatory standards and often additional revenues for companies that service these industries. However, some changes in regulations, 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. In addition, if regulatory authorities were to mandate a significant reduction in safety testing procedures which utilize laboratory animals (as has been advocated by certain groups), certain segments of our business could be materially adversely affected.

        In recent years the U.S. Congress and state legislatures have considered various types of health care 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 health care reform legislation that contains 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. Furthermore, 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.

Our standard customer agreements contain customer-determined termination and service reduction provisions, which may result in less contract revenue than we anticipate.

        Generally, our agreements with our customers provide that the customers can terminate the agreements or reduce the scope of services under the agreements with little or no notice. Customers may elect to terminate their agreements with us for various reasons, including: the products being tested fail to satisfy safety requirements; unexpected or undesired study results; production problems resulting in shortages of the drug being tested; the customer's decision to forego or terminate a particular study; or the loss of funding for the particular research study. If a customer terminates a contract with us, we are entitled under the terms of the contract to receive revenue earned to date as well as certain other costs and, in some cases, penalties. Cancellation of a large contract or proximate cancellation of multiple contracts could materially adversely affect our business (particularly our PCS segment) and, therefore, may adversely affect our operating results.

Many of our contracts are fixed price and may be delayed or terminated or reduced in scope for reasons beyond our control, or we may under price or overrun cost estimates with these contracts, potentially resulting in financial losses.

        Many of our contracts provide for services on a fixed price or fee-for-service with a cap basis and, accordingly, we bear the financial risk if we initially under-price our contracts or otherwise overrun our cost estimates. In addition, these contracts may be terminated or reduced in scope either immediately or upon notice. Cancellations may occur for a variety of reasons, and often at the discretion of the customer. The loss, reduction in scope or delay of a large contract or the loss or delay of multiple

16



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.

Contaminations in our animal populations can damage our inventory, harm our reputation for contaminant-free production, result in decreased sales and cause us to incur additional costs.

        Our research models and fertile chicken eggs must be free of certain adventitious, infectious agents such as certain viruses and bacteria because the presence of these contaminants can distort or compromise the quality of research results and could adversely impact human or animal health. The presence of these infectious agents in our animal production facilities and certain service operations could disrupt our contaminant-free research model and fertile egg production as well as our animal services businesses including transgenic services, harm our reputation for contaminant-free production and result in decreased sales.

        Contaminations typically require cleaning up, renovating, disinfecting, retesting and restarting. Such clean-ups result in inventory loss, clean-up and start-up costs, and reduced sales as a result of lost customer orders and credits for prior shipments. In addition to microbiological contaminations, the potential for genetic mix-ups or mismatings also exists and may require the restarting of the applicable colonies. While this does not require the complete clean-up, renovation and disinfection of the barrier room, it would likely result in inventory loss, additional start-up costs and possibly reduced sales. In addition, contaminations expose us to risks that customers will request compensation for damages in excess of our contractual indemnification requirements. In addition, there exists a risk that contaminations from models that we produce may affect our customer's facilities, with similar impact to them. In some cases, we may be responsible for animals carrying human susceptible diseases, and in the case of contamination, there is possible risk of human exposure.

        All such contaminations described above are unanticipated and difficult to predict and could adversely impact our financial results. We have made significant capital expenditures designed to strengthen our biosecurity and have significantly improved our operating procedures to protect against such contaminations; however, contaminations may still occur.

Our business is subject to risks relating to operating internationally.

        A significant part of our net sales is derived from operations outside the United States. Our international revenues, which include revenues from our non-U.S. subsidiaries, have represented approximately one-half our total net sales in recent years. We expect that international revenues will continue to account for a significant percentage of our revenues for the foreseeable future. There are a number of risks associated with our international business, including:

17


Upgrading and integrating our business systems could result in implementation issues and business disruptions.

        We currently are engaged in a project to replace many of our numerous legacy business systems at our different sites globally with an enterprise wide, integrated enterprise resource planning (ERP) system. The process of planning and preparing for such an integrated, wide-scale implementation is extremely complex and we are required to address a number of challenges including data conversion, system cutover and user training. Problems in any of these areas could cause operational problems during implementation including delayed shipments, missed sales, billing and accounting errors and other operational issues. There have been numerous, well-publicized instances of companies experiencing difficulties with the implementation of ERP systems which resulted in negative business consequences.

        In the course of our planning, we have actively considered the risks of implementation and taken measures to manage the risks, including: incorporating specific steps to mitigate potential risks into our project plan; engaging outside consultants who specialize in ERP implementations to provide assistance and advice on minimizing implementation problems; using industry standard methodologies and practices; and instituting monitoring processes into the project and our preparations for implementations in order to avoid unnecessary risks. Despite these steps to manage risk, there is still a possibility that implementation may occur which could materially and adversely effect us.

Negative attention from special interest groups may impair our business.

        The products and services which we provide our customers are essential to the drug discovery and development process, and are almost universally mandated by law. Notwithstanding, certain special interest groups categorically object to the use of animals for valid research purposes. Historically, our core research model activities with rats, mice and other rodents have not been the subject of significant animal rights media attention. However, research activities with animals have been the subject of adverse attention, impacting the industry. This has included occasional on-site demonstrations at facilities operated by us. Any negative attention or threats directed against our animal research activities in the future could impair our ability to operate our business efficiently.

Several of our product and service offerings are dependent on a limited source of supply, which if interrupted could adversely affect our business.

        We depend on a limited international source of supply of large animal models required in our product and service offerings. Disruptions to their continued supply may arise from health problems, export or import restrictions or embargoes, foreign government or economic instability, severe weather conditions, increased competition amongst suppliers for models, disruptions to the air travel system or other normal-course or unanticipated events. Any disruption of supply could harm our business if we cannot remove the disruption or are unable to secure an alternative or secondary supply source on comparable commercial terms.

18


We may be unable to build out our facilities as anticipated.

        To support our customers' growing demand for drug discovery and development services, including increased strategic focus on outsourcing services and programs, we are engaged in a substantial capacity expansion program, with $227 million spent on capital expenditures in 2007 and another $220-240 million allocated for capital expenditures in 2008. Included in our 2008 capital plan are the following: our new U.S. PCS facility in Nevada, expansions at our Canada, Ohio and Scotland PCS facilities, the construction of a new PCS facility in China, and the construction of our new RMS facility in Maryland. We cannot assure you that any or all of these facilities, or any particular phase of such facilities, will be constructed on the anticipated timetable or on budget. Any material delay in bringing these facilities on-line, or substantial increase in costs to complete these facilities, could materially and adversely affect us. In addition, the costs of these capacity expansion programs may have an adverse impact on our operating margins, particularly within our PCS business.

Any failure by us to comply with applicable regulations and related guidance could harm our reputation and operating results.

        Any failure on our part to comply with applicable regulations could result in the termination of ongoing research or the disqualification of data for submission to regulatory authorities. This could harm our reputation, our prospects for future work and our operating results. For example, if we were to fail to verify that informed consent is obtained from participants in connection with a particular Phase I clinical trial, the data collected from that trial could be disqualified and we might be required to redo the trial at no further cost to our customer, but at substantial cost to us. Furthermore, the issuance of a notice of observations or a warning from the FDA based on a finding of a material violation by us of good clinical practice, good laboratory practice or good manufacturing practice requirements could materially and adversely affect us.

        In addition, regulations and guidance worldwide concerning the production and use of laboratory animals for research purposes continues to be updated. Notably, there has been a recent updating of guidance in Europe that will be implemented over a period of several years on a country-by-country basis. Similarly, guidance has been and continues to be developed for other areas that impact the biomedical research community including transportation and the use of disinfectants. In the United States, an updating of guidance used by the National Institutes of Health and by certain oversight agencies has been recently funded, and it is expected that over the next 3 years, standards will be updated for the care and use of laboratory animals in all aspects of our US business units. These new guidelines could cause us increased costs attributable to additional facilities, the need to add personnel to address new processes, as well as increased administrative burden, and the upgrading of existing facilities.

The drug discovery and development services industry is highly competitive.

        The drug discovery and development services industry is highly competitive. We often compete for business not only with other drug discovery and development companies, but also with internal discovery and development departments within our larger clients, who may have greater resources than ours. We also compete with universities and teaching hospitals. We compete on a variety of factors, including:

19


        If we do not compete successfully, our business will suffer. Increased competition might lead to price and other concessions that might adversely affect our operating results. The drug discovery and development services industry has continued to see a trend towards consolidation, particularly among the biotechnology companies, who are targets for each other and for larger pharmaceutical companies. If this trend continues, it is likely to produce more competition among the larger companies and contract research organizations generally, with respect to both clients and acquisition candidates. In addition, while there are substantial barriers to entry for large, global competitors with broad-based services, small, specialized entities considering entering the contract research organization industry will continue to find lower barriers to entry, and private equity firms may determine that there are opportunities in acquiring and rolling up these companies, thus further increasing possible competition. Furthermore, in recent years both Charles River and our competitors, particularly in the preclinical services area, have been investing in capital projects to increase capacity. An ongoing challenge for all participants is balancing capacity growth and market demand. If capacity has been increased too much, pressure to lower prices or to take on lower-margin studies and projects may occur. These competitive pressures may affect the attractiveness of our services and could adversely affect our financial results.

We could be adversely affected by tax law changes in Canada and the United Kingdom.

        We have substantial operations in Canada and the United Kingdom which currently benefit from favorable corporate tax arrangements. We receive substantial tax credits in Canada from both the Canadian federal and Quebec governments and benefits from tax credits and accelerated tax depreciation allowances in the United Kingdom. Any reduction in the availability or amount of these tax credits or allowances would be likely to have a material adverse effect on profits, cash flow and our effective tax rate.

Impairment of goodwill may adversely impact future results of operations.

        We have intangible assets, including goodwill and other identifiable and indefinite-lived acquired intangibles on our balance sheet due to our acquisitions of businesses. As of December 29, 2007, we had recorded goodwill and other intangibles of $1.3 billion on the consolidated balance sheet. The initial identification and valuation of these intangible assets and the determination of the estimated useful lives at the time of acquisition involve use of management judgments and estimates. These estimates are based on, among other factors, input from accredited valuation consultants, reviews of projected future income cash flows and statutory regulations. The use of alternative estimates and assumptions might have increased or decreased the estimated fair value of our goodwill and other intangible assets and potentially result in a different impact to our results of operations.

20


        We perform an annual review of goodwill to determine if an impairment exists. Goodwill is considered impaired if we determine that the carrying value of the reporting unit exceeds its fair value. Assessing the impairment of goodwill involves making assumptions and judgments regarding the fair value of the net assets of our reporting units. Our assessment is derived from cash flow projections and various key assumptions, strategies, opportunities and risks that are incorporated in our internal strategic review process. We also analyze our market capitalization as compared to a discounted cash flow analysis. We performed annual impairment tests in 2007 and concluded the goodwill and other indefinite-lived intangible asset balances were not impaired. The results of that impairment review are as of a point in time and changes in future business strategy or market conditions could significantly impact the assumptions used in calculating the fair value of these assets in subsequent years.

        Goodwill will not be amortized, but will be reviewed for impairment by us at least annually. If the future growth and operating results of the acquired businesses are not as strong as anticipated, goodwill may be impaired. To the extent goodwill is impaired, its carrying value will be written down to its implied fair value and a charge will be made to our earnings. Such an impairment charge could materially and adversely affect our operating results and financial condition.

Contract research services create a risk of liability.

        In contracting to work on drug development trials, as a contract research organization we face a range of potential liabilities which may include:

        We attempt to mitigate these risks through a variety of methods. Nonetheless, it is impossible to completely eradicate such risks.

        In our RMS business, we mitigate these risks to the best of our abilities through our regimen of animal testing, quarantine, and veterinary staff vigilance, through which we seek to control the exposure of animal related disease or infections.

        In our PCS business, we attempt to reduce these risks by 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 various regulatory requirements we must follow in connection with our business.

21


        In both our RMS and PCS businesses, 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. Furthermore, there can be no assurance that we will be able to maintain such insurance coverage on terms acceptable to us.

If we are unable to attract suitable participants for our Phase I clinical trials, our business might suffer.

        The Phase I clinical research studies we run rely upon the ready accessibility and willing participation of subjects. Participants generally include people from the communities in which the studies are conducted, including our Phase I clinics in Edinburgh, Scotland and Tacoma, Washington, which such communities to date have provided a substantial pool of potential subjects for research studies. Our Phase I clinical research activities could be adversely affected if we were unable to attract suitable and willing participants on a consistent basis.

New technologies may be developed, validated and increasingly used in biomedical research that could reduce demand for some of our products and services.

        For many years, groups within the scientific and research communities have attempted to develop models, methods and systems that would replace or supplement the use of living animals as test subjects in biomedical research. Some companies have developed techniques in these areas, including vaccine development, that may have scientific merit. In addition, technological improvements to existing or new processes, such as imaging technology, could result in a refinement in the number of animal research models necessary to conduct the required research. It is our strategy to participate in some fashion with any non-animal test method as it becomes validated as a research model alternative or adjunct in our markets. However, we may not be successful in commercializing these methods if developed, and sales or profits from these methods may not offset reduced sales or profits from research models. Alternative research methods could decrease the need for research models, and we may not be able to develop new products effectively or in a timely manner to replace any lost sales.

The drug discovery and development industry has a history of patent and other intellectual property litigation, and we might be involved in costly intellectual property lawsuits.

        The drug discovery and development industry has a history of patent and other intellectual property litigation and these lawsuits will likely continue. Accordingly, we face potential patent infringement suits by companies that have patents for similar products and methods used in business or other suits alleging infringement of their intellectual property rights. Legal proceedings relating to intellectual property could be expensive, take significant time and divert management's attention from other business concerns, whether we win or lose. If we do not prevail in an infringement lawsuit brought against us, we might have to pay substantial damages, including treble damages, and we could be required to stop the infringing activity or obtain a license to use technology on unfavorable terms.

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

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

Our debt level could adversely affect our business and growth prospects.

        At December 29, 2007, we had approximately $510.0 million of debt. This debt could have significant adverse effects on our business, including making it more difficult for us to obtain additional

22



financing on favorable terms; requiring us to dedicate a substantial portion of our cash flows from operations to the repayment of debt and the interest on this debt; limiting our ability to capitalize on significant business opportunities; and making us more vulnerable to rising interest rates.

If we are not successful in selecting and integrating the businesses and technologies we acquire, our business may suffer.

        During the past seven years, we have expanded our business through several acquisitions. We plan to continue to acquire businesses and technologies and form alliances. However, businesses and technologies may not be available on terms and conditions we find acceptable. We risk spending time and money investigating and negotiating with potential acquisition or alliance partners, but not completing transactions. Even if completed, acquisitions and alliances involve numerous risks which may include:

        In the event that an acquired business or technology or an alliance does not meet our expectations, our results of operations may be adversely affected.

We could experience a breach of the confidentiality of the information we hold or of the security of our computer systems.

        We operate large and complex computer systems that contain significant amounts of customer data. As a routine element of our business, we collect, analyze and retain substantial amounts of data pertaining to the preclinical and the clinical studies we conduct for our customers. Unauthorized third parties could attempt to gain entry to such computer systems for the purpose of stealing data or disrupting the systems. We believe that we have taken adequate measures to protect them from intrusion, but in the event that our efforts are unsuccessful we could suffer significant harm. Our contracts with our customers typically contain provisions that require us to keep confidential the information generated from these studies. In the event the confidentiality of such information was compromised, we could suffer significant harm.

We depend on key personnel and may not be able to retain these employees or recruit additional qualified personnel, which would harm our business.

        Our success depends to a significant extent on the continued services of our senior management and other members of management. James C. Foster, our Chief Executive Officer since 1992 and Chairman since 2000, has held various positions with us for over 30 years. We have no employment agreement with Mr. Foster or other members of our management. If Mr. Foster or other members of management do not continue in their present positions, our business may suffer.

        Because of the specialized scientific nature of our business, we are highly dependent upon attracting and retaining qualified scientific, technical and managerial personnel. While we have an

23



excellent record of employee retention, there is still strong competition for qualified personnel in the veterinary, pharmaceutical and biotechnology fields. Therefore, we may not be able to attract and retain the qualified personnel necessary for the development of our business. The loss of the services of existing personnel, as well as the failure to recruit additional key scientific, technical and managerial personnel in a timely manner, could harm our business.

Our quarterly operating results may vary, which could negatively affect the market price of our common stock.

        Our results of operations in any quarter may vary from quarter to quarter and are influenced by such factors as:

        We believe that operating results for any particular quarter are not necessarily a meaningful indication of future results. Nonetheless, fluctuations in our quarterly operating results could negatively affect the market price of our common stock

Item 1B.    Unresolved Staff Comments

        There are no unresolved comments to be reported in response to Item 1B.

Item 2.    Properties

        We own or lease the land and buildings where we have facilities. We own large facilities (facilities over 50,000 square feet) for our PCS businesses in the United States, Canada, Scotland and Ireland, and lease large facilities in the United States, Canada and, once completed, China. We have recently brought online new U.S. PCS facilities in Massachusetts and Nevada. We own large RMS facilities in the United Kingdom, France, Germany, Japan, Mexico, Canada and the United States. None of our leases are individually material to our business operations and many have an option to renew. We believe that we will be able to successfully renew expiring leases on terms satisfactory to us. We believe that our facilities are adequate for our operations and that suitable additional space will be available when needed. For additional information see Note [7] to the Consolidated Financial Statements included elsewhere in this Form 10-K.

Item 3.    Legal Proceedings

        We are not a party to any material legal proceedings, other than ordinary routine litigation incidental to our business that is not material to our business or financial condition.

Item 4.    Submission of Matters to a Vote of Security Holders

        Not applicable.

        The Board of Directors of the Company has authorized a share repurchase program, originally authorized on July 27, 2005 and subsequently amended on October 26, 2005, May 9, 2006 and August 1, 2007, to acquire up to a total of $400.0 million of common stock. The program does not have a fixed expiration date.

        During the quarter ended December 29, 2007, the Company repurchased 199,200 shares of common stock for approximately $12.0 million. The timing and amount of any future repurchases will depend on market conditions and corporate considerations. Additionally, the Company's Incentive Plans permit the netting of common stock upon vesting of restricted stock awards in order to satisfy individual tax withholding requirements. Accordingly, during the quarter ended December 29, 2007, the Company acquired 1,144 shares as a result of such withholdings.

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

Overview

        We are a leading global provider of solutions that accelerate the drug discovery and development process, including research models and associated services and outsourced preclinical services. We partner with global pharmaceutical companies, a wide range of biotechnology companies, as well as government agencies, leading hospitals and academic institutions throughout the world in order to bring drugs to market faster and more efficiently. Our broad portfolio of products and services enables our customers to reduce costs, increase speed to market and enhance their productivity and effectiveness in drug discovery and development. We currently operate over 60 facilities in 15 countries worldwide. We have been in business for 60 years. We have built upon our core competency of laboratory animal medicine and science (research model technologies) to develop a diverse and growing portfolio of regulatory compliant preclinical services which address drug discovery and development in the preclinical arena.

        Our sales growth in 2007 was driven by continued spending by major pharmaceuticals, biotechnology companies and academic institutions on our global products and services, which aid in their development of new drugs and products. We expect future drivers for our business as a whole primarily to be our customers' continued growing demand for drug discovery and development services, including their increased strategic focus on outsourcing.

        We expect our on-going capacity expansion program along with our continued focus on our core competencies of laboratory animal medicine and science and regulatory compliant preclinical services to position us to take advantage of these growing opportunities for our business. Through our capacity expansion program we intend to take advantage of the long-term opportunities made available by our customers' demands and focus, particularly within the Preclinical Services (PCS) business. For instance, we opened our new preclinical site in Massachusetts and Scotland expansion in 2007 and our new Nevada preclinical site in early 2008. Additionally, in 2008 we are constructing additional preclinical capacity in Canada, China, Ohio and Scotland. We have commenced construction of our new China facility, which we believe will enable us to be the partner of choice for our global pharmaceutical customers as they establish and expand research and development activities in China. In addition, the opening of our California Research Models and Services (RMS) expansion and the ground breaking of our facility in Maryland, which will support the National Cancer Institute (NCI) contract and commercial production, reflect our commitment to address demand for our RMS products and services. Our capital expenditures of $227.0 million in 2007, and our planned capital expenditures in the range of $220 million to $240 million in 2008, reflect our ongoing commitment to this strategy. In addition to internally generated organic growth, our business strategy includes strategic "bolt-on" acquisitions that complement our business and geographically expand our existing services.

        Total net sales in 2007 were $1.2 billion, an increase of 16.3% over the same period last year. The sales increase was due primarily to increased customer demand, higher pricing and the full year impact of the Northwest Kinetics Phase I clinical business acquired in late 2006. The positive effect of foreign currency translation was 2.9%. Our gross margin increased to 38.9% of net sales, compared to 38.4% of net sales for 2006, due mainly to favorable results in RMS and many PCS locations, partially offset by transition costs for our PCS Massachusetts facilities.

        Operating income for the year was $227.2 million compared to $188.2 million for 2006. The operating margin increased to 18.5% compared to 17.8% for the prior year primarily due to improved margins in our RMS business and lower amortization, partially offset by costs in our PCS segment due to the Massachusetts transition.

        Net income from continuing operations was $157.6 million in 2007 compared to $125.2 million in 2006. Diluted earnings per share from continuing operations for 2007 were $2.29 compared to $1.79 in 2006.

30


        We report two segments: RMS and PCS, which reflect the manner in which our operating units are managed.

        Our RMS segment, which represented 46.9% of net sales in 2007, includes sales of research models, transgenic services, research animal diagnostics, discovery services, consulting and staffing services, vaccine support and in vitro technology (primarily endotoxin testing). Net sales for this segment increased 12.1% compared to 2006, due to increased research model sales in the United States and Europe, increased transgenic sales and strong in vitro sales, partially offset by lower research model sales in Japan. Favorable foreign currency translation increased the net sales gain by 2.9%. We experienced increases in both the RMS gross margin and operating margin, (to 43.2% from 41.6%, and to 30.7% from 28.7%, respectively), mainly due to price increases along with improved capacity utilization resulting from higher sales volume.

        Our PCS segment, which represented 53.1% of net sales in 2007, includes services required to take a drug through the development process including discovery support, toxicology, pathology, biopharmaceutical, bioanalysis, pharmacokinetics and drug metabolism services as well as Phase I clinical trials. Sales for this segment increased 20.2% over 2006. We experienced favorable market conditions as demand for toxicology services particularly remained strong. Favorable foreign currency increased sales growth by 2.9%. The gross margin for PCS declined to 35.0% from 35.4% in 2006, due primarily to the transition costs of the Massachusetts facilities and the foreign exchange impact of the strengthening Canadian dollar, partially offset by improvement to most PCS locations. The operating margin increased to 15.8% of net sales compared to 15.2% of net sales in 2006 due mainly to lower amortization expense, which was partially offset by transition costs of the Massachusetts facilities. We expect to see increasing levels of customer demand for general and speciality toxicology studies. We continue to focus on meeting the growing demand for our preclinical services and increased outsourcing trends through our expansion program.

Discontinued Operations

        Our former Phase II-IV Clinical Services and our Interventional and Surgical Services (ISS) businesses are reported as discontinued operations. Net loss from discontinued operations for 2007 was $3.1 million. In 2006, net loss of $181.0 million was due mainly to charges related to the write down of goodwill and impaired assets related to the Phase II-IV business along with tax expense of $45.3 million related to the sale of discontinued operations.

Net Income

        Net income (loss) for 2007 was $154.4 million compared to $(55.8) million in 2006.

Critical Accounting Policies and Estimates

        The preparation of these financial statements requires management to use judgment when making assumptions that are involved in preparing estimates that affect the reported amounts of assets, liabilities, revenues and expenses during the reporting period. On an ongoing basis, management evaluates its estimates and assumptions. Some of those estimates can be complex and require management to make estimates about the future and actual results could differ from those estimates. Management bases its estimates and assumptions on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. For any given estimate or assumption made by management, there may also be other estimates or assumptions that are reasonable.

        Management's Discussion and Analysis of Financial Condition and Results of Operations discusses the consolidated financial statements of Charles River Laboratories International, Inc. which have been prepared in accordance with accounting principles generally accepted in the United States. Management believes the following critical accounting policies are most affected by significant

31



judgments and estimates used in the preparation of our consolidated financial statements. The following summary should be read in conjunction with our consolidated financial statements and the related notes included elsewhere in this Form 10-K. We believe the following critical accounting policies and estimates reflect our more significant judgments and estimates than usual in the preparation of our consolidated financial statement:

        Goodwill, Other Intangible Assets    We have intangible assets, including goodwill and other identifiable finite and indefinite-lived acquired intangibles on our balance sheet due to businesses we acquired. The identification and valuation of these intangible assets and the determination of the estimated useful lives at the time of acquisition require significant management judgments and estimates. These estimates are made based on, among others, input from an accredited valuation consultant, reviews of projected future income cash flows and statutory regulations. The use of alternative estimates and assumptions could increase or decrease the estimated fair value of our goodwill and other intangible assets, and potentially result in a different impact to our results of operations.

        We perform an annual review of goodwill to determine if an impairment exists. Goodwill is considered impaired if we determine that the carrying value of the reporting unit exceeds its fair value. Assessing the impairment of goodwill requires us to make assumptions and judgments regarding the fair value of the net assets of our reporting units. Our evaluation includes management estimates of cash flow projections based on an internal strategic review. Key assumptions, strategies, opportunities and risks from this strategic review along with a market evaluation are the basis for our assessment. Our market capitalization was also compared to the discounted cash flow analysis. We performed an annual impairment test in 2007 and concluded the goodwill and other indefinite-lived intangible asset balances were not impaired. As of December 29, 2007, we had recorded goodwill and other intangibles of $1.3 billion in the consolidated balance sheet. The results of this year's impairment review are as of a point in time and changes in future business strategy or market conditions could significantly impact the assumptions used in calculating the fair value of these assets in subsequent years.

        Revenue Recognition    We recognize revenue on product and services sales. We record product revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price to the buyer is fixed or determinable and collectibility is reasonably assured. Recognition of service revenue is primarily based on the completion of agreed-upon service procedures including rate specified contracts and fixed fee contracts. Revenue of agreed-upon rate contracts is recognized as services are performed, based on rates specified in the contract. Revenue of fixed fee contracts is recognized as services are performed in relation to estimated costs to complete procedures specified by the customers in the form of study protocols. Our fixed fee service contracts, which are utilized mainly in our Preclinical segment, vary in term from a few days to greater than a year, with the majority of such contracts having a term of less than six months. On a monthly basis, management reviews the costs incurred and services provided to date on these contracts in relation to the total estimated effort to complete the contract. As a result of the monthly reviews, revisions in estimated effort to complete the contract are reflected in the period in which the change became known. These judgments and estimates are not expected to result in a change that would materially effect our reported results. In some cases, a portion of the contract fee is paid at the time the study is initiated. These advances are deferred and recognized as revenue as services are performed. Conversely, in some cases, revenue is recorded based on the level of service performed in advance of billing the customer with the offset to unbilled receivable. As of

32



December 29, 2007, we had recorded unbilled revenue of $52.0 million and deferred revenue of $102.0 million in our consolidated balance sheet based on the difference between the estimated level of services performed and the billing arrangements defined by our service contracts.

        Pension Plan Accounting    As of December 29, 2007, we had a pension liability of $36.6 million. The actuarial computations require the use of assumptions to estimate the total benefits ultimately payable to employees and allocate this cost to the service periods. The key assumptions include the discount rate, the expected return on plan assets and expected future rate of salary increases. In addition, our actuaries determine the expense or liability of the plan using other assumptions for future experiences such as withdrawal and mortality rate. The key assumptions used to calculate pension costs are determined and reviewed annually by management after consulting with outside investment advisors and actuaries. The assumed discount rate, which is intended to be the actual rate at which benefits could effectively be settled, is adjusted based on the change in the long-term bond yield as of the measurement date. As of December 29, 2007 the weighted-average discount rate for our pension plans was 5.14%.

        The assumed expected return on plan assets is the average return expected on the funds invested or to be invested to provide future benefits to pension plan participants. This includes considering the assets allocation and expected returns likely to be earned over the life of the plan. If the actual return is different from the assumed expected return in plan assets, the difference would be amortized over a period of approximately 15 to 20 years. The estimated effect of a 1.0% change in the expected rate of return would increase or decrease pension expense by $1.9 million annually.

        Stock-based Compensation    Effective January 1, 2006, we adopted, on a modified prospective basis, the provisions of SFAS No. 123(R), and related guidance which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and directors including employee stock options and restricted stock awards based on estimated fair values. Accordingly, stock-based compensation cost is measured at grant date, based on the estimated fair value of the award and is recognized as expense on a straight-line basis over the requisite service period which is generally the vesting period. During the year ended December 29, 2007, we recognized $26.0 million of stock compensation expense associated with stock options, restricted stock and performance based stock awards.

        We estimate the fair value of stock options using the Black-Scholes option-pricing model and the fair value of our restricted stock awards and restricted stock units based on the quoted market price of our common stock. We recognize the associated compensation expense on a straight-line basis over the vesting periods of the awards, net of estimated forfeitures. Forfeiture rates are estimated based on historical pre-vesting forfeitures and are updated on vesting date to reflect actual forfeitures.

        Estimating the fair value for stock options requires judgment, including estimating stock-price volatility, expected term, expected dividends and risk-free interest rates. The expected volatility rates are estimated based on historical volatilities of our common stock over a period of time that approximates the expected term of the options. The expected term represents the average time that options are expected to be outstanding and is estimated based on the historical exercise and post-vesting cancellation patterns of our stock options. Expected dividends are estimated based on our dividend history as well as our current projections. The risk free interest rate is based on the market yield of U.S. Treasury securities for periods approximating the expected terms of the options in effect at the time of grant. These assumptions are updated on at least an annual basis or when there is a significant change in circumstances that could affect these assumptions.

33


        The fair value of option based stock awards granted during 2007 was estimated on the grant date using the Black-Scholes option pricing model with the following weighted-average assumptions:

 
  December 29, 2007
 
Expected life (in years)     5.0  
Expected volatility     30.0 %
Risk-free interest rate     4.6 %
Expected dividend yield     0.0 %
Weighted-average option grant date fair value   $ 16.49  

        Income Taxes    As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves estimating our current tax expense and assessing temporary and permanent differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included in our consolidated balance sheet. In certain cases, we must assess the likelihood that our deferred tax assets will be recovered from future taxable income and, to the extent we believe that recovery is not likely, we must establish a valuation allowance. In the event that actual results differ from these estimates, or we adjust these estimates in future periods, we may need to establish an additional valuation allowance which could impact our financial position or results of operations.

        As of December 29, 2007, earnings of non-U.S. subsidiaries considered to be indefinitely reinvested totaled $349.1 million. No provision for U.S. income taxes has been provided thereon. Upon distribution of those earnings in the form of dividends or otherwise, we would be subject to both U.S. taxes and withholding taxes payable to the various foreign countries. It is not practicable to estimate the amount of additional tax that might be payable on this undistributed foreign income.

        We are a worldwide business and operate in various tax jurisdictions where tax laws and tax rates are subject to change given the political and economic climate in these countries. We report and pay income taxes based upon operational results and applicable law. Our tax provision contemplates tax rates in effect to determine both the current and deferred tax position. Any significant fluctuation in rates or in tax laws could cause our estimate of taxes that we anticipate to change. These changes could result in either increases or decreases in our effective tax rate.

        Effective December 31, 2006, we adopted the provisions of FIN 48 "Accounting for Uncertainty in Income Taxes-an interpretation of FASB Statement No. 109," which clarifies the accounting for income tax positions by prescribing a minimum recognition threshold that a tax position is required to meet before being recognized in the financial statements. FIN 48 also provides guidance on the derecognition of previously recognized income tax items, measurement, classification, interest and penalties, accounting in interim periods and financial statement disclosure. Under FIN 48, we recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities, based on the technical merits of the tax position. The tax benefits recognized in our financial statements from such positions are measured on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution.

        Due to our size and the number of tax jurisdictions within which we conduct our global business operations, we are subject to income tax audits on a regular basis. As a result, we have tax reserves which are attributable to potential tax obligations around the world. We believe we have sufficiently provided for all audit exposures and assessments. Settlements of these audits or the expiration of the statute of limitations on the assessment of income taxes for any tax year may result in an increase or reduction of future tax positions.

Fiscal 2007 Compared to Fiscal 2006

        Net Sales.    Net sales in 2007 were $1,230.6 million, an increase of $172.2 million, or 16.3%, from $1,058.4 million in 2006.

        Research Models and Services.    In 2007, net sales from our RMS segment were $577.2 million, an increase of $62.2 million, or 12.1%, from $515.0 million in 2006. Favorable foreign currency translation increased our net sales gain by 2.9%. RMS sales increased due to pricing and unit volume increases in both models and services. The RMS sales growth was driven by increases in basic research and biotechnology spending, which drove greater demand for our products and services, partially offset by lower sales growth in research models in Japan.

        Preclinical Services.    In 2007, net sales from our Preclinical Services segment were $653.4 million, an increase of $110.0 million, or 20.2%, compared to $543.4 million in 2006. The increase was primarily due to the increased customer demand for toxicology and other specialty preclinical services, reflecting increased customer outsourcing along with the full year impact of the acquisition of Northwest Kinetics. Favorable foreign currency increased sales growth by 2.9%.

        Cost of Products Sold and Services Provided.    Cost of products sold and services provided in 2007 was $752.4 million, an increase of $100.7 million, or 15.4%, from $651.8 million in 2006. Cost of products sold and services provided in 2007 was 61.1% of net sales, compared to 61.6% in 2006.

        Research Models and Services.    Cost of products sold and services provided for RMS in 2007 was $327.9 million, an increase of $27.0 million, or 9.0%, compared to $300.9 million in 2006. Cost of products sold and services provided in 2007 decreased to 56.8% of net sales compared to 58.4% of net sales in 2006. The favorable cost of products sold and services provided as a percentage of sales was due to greater facility utilization as a result of increased sales.

        Preclinical Services.    Cost of services provided for the Preclinical Services segment in 2007 was $424.6 million, an increase of $73.6 million, or 21.0%, compared to $350.9 million in 2006. Cost of services provided as a percentage of net sales was 65.0% in 2007, compared to 64.6% in 2006. The increase in cost of services provided as a percentage of net sales was primarily due to the impact of increased costs related to the transition to our new Massachusetts facility and the foreign exchange

36



impact of the strengthening Canadian dollar, partially offset by improved performance at certain PCS locations.

        Selling, General and Administrative Expenses.    Selling, general and administrative expenses in 2007 were $217.5 million, an increase of $36.7 million, or 20.3%, from $180.8 million in 2006. Selling, general and administrative expenses in 2007 were 17.7% of net sales compared to 17.1% of net sales in 2006. The increase as a percentage of sales was due primarily to increases in unallocated corporate overhead and charges related to the accelerated exit of our Worcester facility.

        Research Models and Services.    Selling, general and administrative expenses for RMS in 2007 were $70.3 million, an increase of $4.4 million, or 6.8%, compared to $65.9 million in 2006. Selling, general and administrative expenses decreased as a percentage of sales to 12.2% in 2007 from 12.8% in 2006 due mainly to greater economies of scale.

        Preclinical Services.    Selling, general and administrative expenses for the Preclinical Services segment in 2007 were $93.7 million, an increase of $20.7 million, or 28.3%, compared to $73.0 million in 2006. Selling, general and administrative expenses in 2007 increased to 14.3% of net sales, compared to 13.4% of net sales in 2006 due to charges related to the accelerated exit of our Worcester facility.

        Unallocated Corporate Overhead.    Unallocated corporate overhead, which consists of various corporate expenses including those associated with stock based compensation, pension and departments such as senior executives, corporate accounting, legal, tax, treasury, global informational technology, human resources and investor relations, was $53.5 million in 2007, compared to $41.9 million in 2006. The increase in unallocated corporate overhead in 2007 was due to increased equity based compensation, higher information technology costs and higher bonus accruals.

        Amortization of Other Intangibles.    Amortization of other intangibles in 2007 was $33.5 million, a decrease of $4.1 million, from $37.6 million in 2006. The decreased amortization was primarily due to reduced amortization related to the acquisition of Inveresk.

        Research Models and Services.    In 2007, amortization of other intangibles for our RMS segment was $1.9 million, an increase of $1.4 million from $0.5 million in 2006. The increased amortization was primarily due to the acquisition of the remaining 15% of the equity of Charles River Laboratories Japan, Inc., from the minority interest partner in the first quarter of 2007.

        Preclinical Services.    In 2007, amortization of other intangibles for our Preclinical Services segment was $31.6 million, a decrease of $5.6 million from $37.2 million in 2006. The decrease in amortization of other intangibles was primarily due to reduced amortization related to the Inveresk acquisition.

        Operating Income.    Operating income in 2007 was $227.2 million, an increase of $39.0 million, or 20.7%, from $188.2 million in 2006. Operating income in 2007 was 18.5% of net sales, compared to 17.8% of net sales in 2006. The increase as a percentage of sales was due primarily to increased operating income margins in RMS along with lower amortization costs.

        Research Models and Services.    In 2007, operating income for our RMS segment was $177.2 million, an increase of $29.4 million, or 19.9%, from $147.8 million in 2006. Operating income as a percentage of net sales in 2007 was 30.7%, compared to 28.7% in 2006. The increase in operating income as a percentage of sales was primarily due to improved capacity utilization resulting from the higher sales volume.

        Preclinical Services.    In 2007, operating income for our Preclinical Services segment was $103.5 million, an increase of $21.2 million, or 25.8%, from $82.3 million in 2006. Operating income as a percentage of net sales increased to 15.8%, compared to 15.2% of net sales in 2006. The increase in operating income as a percentage of net sales was primarily due to higher sales which resulted in improved operating efficiency and lower amortization costs, partially offset by the start-up and

37



transition costs for our PCS Massachusetts facilities and the foreign exchange impact of the strengthening Canadian dollar.

        Interest Income.    Interest income in 2007 was $9.7 million, compared to $6.8 million in 2006. The $2.9 million increase was primarily due to increased funds invested.

        Interest Expense.    Interest expense in 2007 was $18.0 million, compared to $19.4 million in 2006. The $1.4 million decrease was primarily due to debt repayment.

        Income Taxes.    Income tax expense for 2007 was $59.4 million, an increase of $9.7 million compared to $49.7 million in 2006 due mainly to higher income before income tax.

        Income from Continuing Operations.    Income from continuing operations in 2007 was $157.6 million, an increase of $32.3 million from $125.2 million in 2006.

        Loss from Discontinued Operations.    The loss from discontinued operations in 2007 was $3.1 million. The loss from discontinued operations for 2006 was $181.0 million which included a goodwill impairment of $129.2 million, the tax expense of $37.8 million related to the sale of the Phase II-IV Clinical business, as well as results from our ISS business.

        Net Income (Loss).    Net income in 2007 was $154.4 million compared to a net loss of $(55.8) million in 2006.

Fiscal 2006 Compared to Fiscal 2005

        Net Sales.    Net sales in 2006 were $1,058.4 million, an increase of $65.1 million, or 6.5%, from $993.3 million in 2005.

        Research Models and Services.    In 2006, net sales from our RMS segment were $515.0 million, an increase of $11.8 million, or 2.4%, from $503.2 million in 2005. Unfavorable foreign currency translation reduced our net sales gain by 0.4%. RMS sales increased due to pricing and unit volume increases in both models and services. The RMS sales growth was driven by increases in basic research and biotechnology spending, which drove greater demand for our products and services, partially offset by continued slowdown in the transgenic services business and lower large model sales.

        Preclinical Services.    In 2006, net sales from our Preclinical Services segment were $543.4 million, an increase of $53.2 million, or 10.9%, compared to $490.2 million in 2005. The increase was primarily due to the increased customer demand for toxicology and other specialty preclinical services, reflecting increased drug development efforts and customer outsourcing. Favorable foreign currency increased sales growth by 0.7%.

        Cost of Products Sold and Services Provided.    Cost of products sold and services provided in 2006 was $651.8 million, an increase of $48.2 million, or 8.0%, from $603.6 million in 2005. Cost of products sold and services provided in 2006 was 61.6% of net sales, compared to 60.8% in 2005 due to stock compensation expense and higher costs in RMS.

        Research Models and Services.    Cost of products sold and services provided for RMS in 2006 was $300.9 million, an increase of $13.3 million, or 4.6%, compared to $287.6 million in 2005. Cost of products sold and services provided in 2006 increased to 58.4% of net sales compared to 57.2% of net sales in 2005. The continued slowdown in the transgenic services business, lower large model sales, lower research model sales mainly in Japan, stock compensation expense, second quarter cost-saving initiatives which included the shutdown of two small vaccine sites and higher delivery costs all adversely impacted the cost of products sold and services provided as a percent of sales.

        Preclinical Services.    Cost of services provided for the Preclinical Services segment in 2006 was $350.9 million, an increase of $34.9 million, or 11.0%, compared to $316.0 million in 2005. Cost of services provided as a percentage of net sales was 64.6% in 2006, compared to 64.5% in 2005. The

38



increase in cost of services provided as a percentage of net sales was primarily due to stock compensation expense partially offset by improved capacity utilization resulting from the increased sales of services.

        Selling, General and Administrative Expenses.    Selling, general and administrative expenses in 2006 were $180.8 million, an increase of $22.8 million, or 14.4%, from $158.0 million in 2005. Selling, general and administrative expenses in 2006 were 17.1% of net sales compared to 15.9% of net sales in 2005. The increase as a percent of sales was due primarily to the impact of stock compensation expense.

        Research Models and Services.    Selling, general and administrative expenses for RMS in 2006 were $65.9 million, an increase of $10.4 million, or 18.7%, compared to $55.5 million in 2005. Selling, general and administrative expenses increased slightly as a percentage of sales to 12.8% in 2006 from 11.0% in 2005 due mainly to stock compensation expense.

        Preclinical Services.    Selling, general and administrative expenses for the Preclinical Services segment in 2006 were $73.0 million, an increase of $13.5 million, or 22.7%, compared to $59.5 million in 2005. Selling, general and administrative expenses in 2006 increased to 13.4% of net sales, compared to 12.1% of net sales in 2005. The increase in selling, general and administrative expenses as a percent of sales in 2006 was due primarily to the increased stock compensation expense.

        Unallocated Corporate Overhead.    Unallocated corporate overhead, which consists of various corporate expenses including those associated with stock based compensation, pension, and departments such as senior executives, corporate accounting, legal, tax, treasury, human resources and investor relations, was $41.9 million in 2006, compared to $43.0 million in 2005. The decrease in unallocated corporate overhead in 2006 was due to reduced restricted stock compensation expense.

        Amortization of Other Intangibles.    Amortization of other intangibles in 2006 was $37.6 million, a decrease of $9.4 million, from $47.0 million in 2005. The decreased amortization was primarily due to reduced amortization related to the acquisition of Inveresk.

        Research Models and Services.    In 2006, amortization of other intangibles for our RMS segment was $0.5 million, an increase of $0.2 million from $0.3 million in 2005.

        Preclinical Services.    In 2006, amortization of other intangibles for our Preclinical Services segment was $37.2 million, a decrease of $9.5 million from $46.7 million in 2005. The decrease in amortization of other intangibles was primarily due to reduced amortization related to the Inveresk acquisition.

        Operating Income.    Operating income in 2006 was $188.2 million, an increase of $3.5 million, or 1.9%, from $184.7 million in 2005. Operating income in 2006 was 17.8% of net sales, compared to 18.6% of net sales in 2005. The decrease as a percent of sales was due primarily to stock compensation expense.

        Research Models and Services.    In 2006, operating income for our RMS segment was $147.8 million, an decrease of $12.0 million, or 7.5%, from $159.8 million in 2005. Operating income as a percentage of net sales in 2006 was 28.7%, compared to 31.8% in 2005. The decrease in operating income as a percent to sales was primarily due to increase in cost of products sold and services provided due to stock compensation expense, the slowdown in the Transgenic Services business and lower large model sales.

        Preclinical Services.    In 2006, operating income for our Preclinical Services segment was $82.3 million, an increase of $14.4 million, or 21.2%, from $67.9 million in 2005. Operating income as a percentage of net sales increased to 15.1%, compared to 13.9% of net sales in 2005. The increase in operating income as a percentage of net sales was primarily due to higher sales which resulted in improved operating efficiency and lower amortization costs, partially offset by stock compensation expense and cost-saving initiatives.

39


        Interest Income.    Interest income in 2006 was $6.8 million, compared to $3.7 million in 2005. The $3.1 million increase was primarily due to increased funds invested.

        Interest Expense.    Interest expense in 2006 was $19.4 million, compared to $24.3 million in 2005. The $4.9 million decrease was primarily due to debt repayment.

        Income Taxes.    Income tax expense for 2006 was $49.7 million an increase of $33.4 million compared to $16.3 million in 2005. The increase was primarily attributable to the one time 2005 net benefit of $28.3 million or 17.3%, from the effects of a distribution under the AJCA of $24.1 million and the 2005 change of the Company's assertion with respect to the remaining Inveresk pre-acquisition earnings of $29.2 million, offset by the 2005 tax charge related to the Company's restructuring of its UK operations as a part of the plan of distribution of $23.1 million and a charge of $1.9 million related to the write off of deferred tax assets.

        Income from Continuing Operations.    Income from continuing operations in 2006 was $125.2 million, a decrease of $20.6 million from $145.8 million in 2005.

        Loss from Discontinued Operations.    The loss from discontinued operations was $181.0 million due mainly to the goodwill impairment in the first quarter.

        Net Income (Loss).    Net income (loss) in 2006 was $(55.8) million compared to $142.0 in 2005.

Liquidity and Capital Resources

        The following discussion analyzes liquidity and capital resources by operating, investing and financing activities as presented in our condensed consolidated statements of cash flows.

        Our principal sources of liquidity have been our cash flow from operations, the convertible debt offering, our marketable securities and our revolving line of credit arrangements.

        On June 12, 2006, we issued $350.0 million aggregate principal amount of convertible senior subordinated notes (the 2013 Notes) in a private placement with net proceeds to the Company of $343.0 million. The 2013 Notes bear interest at 2.25% per annum, payable semi-annually, and mature on June 15, 2013. The 2013 Notes are convertible into cash and shares of common stock (or, at the Company's election, cash in lieu of some or all of such common stock) based on an initial conversion rate, subject to adjustment, of 20.4337 shares of common stock per $1,000 principal amount of notes (which represents an initial conversion price of $48.94 per share).

        Concurrently with the sale of the 2013 Notes, we entered into convertible note hedge transactions with respect to our obligation to deliver common stock under the 2013 Notes. The convertible note hedges give us the right to receive, for no additional consideration, the numbers of shares of common stock that we are obligated to deliver upon conversion of the 2013 Notes (subject to antidilution adjustments substantially identical to those in the 2013 Notes), and expire on June 15, 2013. The aggregate cost of these convertible note hedges was $98.3 million.

        Separately and concurrently with the pricing of the 2013 Notes, we issued warrants for approximately 7.2 million shares of our common stock. The warrants give the holders the right to receive, for no additional consideration, cash or shares (at our option) with a value equal to the appreciation in the price of our shares above $59.925, and expire between September 13, 2013 and January 22, 2014 over 90 equal increments. The total proceeds from the issuance of the warrants were $65.4 million.

        From our economic perspective, the cumulative impact of the purchase of the convertible note hedges and the sale of the warrants increases the effective conversion price of the 2013 Notes from $48.94 to $59.25 per share.

        On July 31, 2006, we amended and restated our $660.0 million credit agreement to reduce the current interest rate, modify certain restrictive covenants and extend the term. The amount of debt

40



outstanding under the original $660.0 million credit agreement remained the same at the time of amendment. The now $428.0 million credit agreement provides for a $156.0 million U.S. term loan facility, a $200.0 million U.S. revolving facility, a C$57.8 million term loan facility and a C$12.0 million revolving facility for a Canadian subsidiary, and a GBP 6.0 million revolving facility for a U.K. subsidiary. The $156.0 million term loan facility matures in 20 quarterly installments with the last installment due June 30, 2011. As of December 29, 2007, we had $109.2 million outstanding on the U.S. term loan. The $200.0 million U.S. revolving facility matures on July 31, 2011 and requires no scheduled payment before that date. Under specified circumstances, the $200.0 million U.S. revolving facility may be increased by $100.0 million. The Canadian term loan was repaid during 2007. The Canadian and U.K. revolving facilities mature on July 31, 2011 and require no scheduled prepayment before that date. The interest rate applicable to the Canadian term loan and the Canadian and U.K. revolving loans under the credit agreement is the adjusted LIBOR rate in its relevant currency plus an interest rate margin based upon our leverage ratio. The interest rates applicable to term loans and revolving loans under the credit agreement are, at our option, equal to either the base rate (which is the higher of the prime rate or the federal funds rate plus 0.50%) or the adjusted LIBOR rate plus an interest rate margin based upon our leverage ratio. Based on our leverage ratio, the margin range for LIBOR based loans is 0.625% to 0.875%. The interest rate margin was 0.75% as of December 29, 2007. We have pledged the stock of certain subsidiaries as well as certain U.S. assets as security for the $428.0 million credit agreement. The $428.0 million credit agreement includes certain customary representations and warranties, negative and affirmative covenants and events of default. We had $5.5 million and $5.4 million outstanding under letters of credit as of December 29, 2007 and December 30, 2006, respectively. During 2007, we did not borrow under our revolving credit facilities. As of December 29, 2007, there were no outstanding balances on the revolving facilities.

        On July 27, 2005, we entered into a $50 million credit agreement ($50 million credit agreement), which was subsequently amended on December 20, 2005 and again on July 31, 2006 to reflect substantially the same modifications made to the covenants in the $660 million and $428 million credit agreements, respectively. On June 15, 2007, we executed a third amendment to the $50 million credit agreement to extend the maturity date and reduce the interest rate. The $50 million credit agreement provides for a $50 million term loan facility which matures on June 22, 2010. Prior to the amendment, the interest rate applicable to term loans under the credit agreement was, at our option, equal to either the base rate (which was the higher of the prime rate or the federal funds rate plus 0.50%) or the LIBOR rate plus 0.75%. From June 15, 2007 through June 21, 2008, the interest rates applicable to term loans under the credit agreement are, at our option, equal to either the base rate (which is the higher of the prime rate or the federal funds rate plus 0.50%) minus 2.25% or the LIBOR rate plus 0.50%. Commencing June 22, 2008 through June 22, 2010, the applicable interest rates are equal to either the base rate (which is the higher of the prime rate or the federal funds rate plus 0.50%) or the adjusted LIBOR rate plus an interest rate margin based on our leverage ratio. The $50 million credit agreement includes certain customary representations and warranties, negative and affirmative covenants and events of default. As of December 29, 2007, the entire balance of the $50 million credit agreement was outstanding.

        Our Board of Directors has authorized a share repurchase program, originally authorized on July 27, 2005 and subsequently amended on October 26, 2005, May 9, 2006 and August 1, 2007, to acquire up to a total of $400.0 million of common stock. The program does not have a fixed expiration date. In order to facilitate these share repurchases, the Company has entered into Rule 10b5-1 Purchase Plans. As of December 29, 2007, approximately $96.4 million remained authorized for share repurchases.

        We had marketable securities of $63.4 million and $111.4 million as of December 29, 2007 and December 30, 2006, respectively. The decline was primarily due to funding our capital expansion program. As of December 29, 2007, we had $38.2 million invested in auction rate securities rated AAA by a major credit rating agency. Our auction rate securities are guaranteed by U.S. federal agencies or commercial insurance carriers.

41


        As of February 13, 2008 we had $21.2 million of our investment portfolio invested in AAA rated and government guaranteed auction rate securities. The current overall credit concerns in capital markets may impact our ability to liquidate these securities. These auction rate securities provide liquidity via an auction process that resets the applicable interest rate at predetermined calendar intervals, usually every 35 days. If the auctions for the securities we own fail, the investments may not be readily convertible to cash until a future auction of these investments is successful. During the first quarter of 2008, auctions for $14.2 million of our investments in auction rate securities failed. Based on our ability to access our cash and other short-term investments, our expected operating cash flows, and our other sources of cash, we do not anticipate the current lack of liquidity on these investments will affect our ability to operate our business as usual.

        Cash and cash equivalents totaled $225.4 million at December 29, 2007, compared to $175.4 million at December 30, 2006.

        Net cash provided by operating activities in 2007 and 2006 was $288.4 million and $176.0 million, respectively. The increase in cash provided by operations was primarily due to increased income from continuing operations as well as changes in accounts receivable and deferred income. Our days sales outstanding decreased to 35 days as of December 29, 2007, from 39 days as of December 30, 2006 due mainly to increased deferred revenue. Our days sales outstanding includes deferred revenue as an offset to accounts receivable in the calculation.

        Net cash used in investing activities in 2007 and 2006 was $200.8 million and $297.4 million, respectively. Our capital expenditures in 2007 were $227.0 million of which $51.0 million was related to RMS and $176.0 million to Preclinical Services. For 2008, we project capital expenditures to be in the range of $220—$240 million. We anticipate that future capital expenditures will be funded by operating activities and existing credit facilities.

        Net cash used in financing activities in 2007 was $46.4 million and cash provided by financing activities in 2006 was $5.6 million. During 2007, we purchased $41.6 million of treasury stock and repaid $64.5 million of debt, partially offset by proceeds from exercises of employee stock options of $54.0 million. During 2006, we received proceeds of $440.3 million of long-term debt, partially offset by our purchase of $250.0 million of treasury stock and our repayment of debt of $170.8 million.

        Minimum future payments of our contractual obligations at December 29, 2007 are as follows:

Contractual Obligations

  Total
  Less than
1 Year

  1—3 Years
  3—5 Years
  After
5 Years

Debt   $ 510.0   $ 25.1   $ 111.5   $ 23.4   $ 350.0
Interest payments     71.6     17.0     30.0     24.6    
Operating leases     83.4     24.9     27.7     10.7     20.1
Pension     77.2     6.1     11.0     13.5     46.6
Construction commitments     99.5     99.5            
   
 
 
 
 
  Total contractual cash obligations   $ 841.7   $ 172.6   $ 180.2   $ 72.2   $ 416.7
   
 
 
 
 

        The above table does not reflect unrecognized tax benefits of $22.1 million the timing of which is uncertain. Refer to Note 7 to the Consolidated Financial Statements for additional discussion on unrecognized tax benefits.

Off-Balance Sheet Arrangements

        The conversion features of our 2013 Notes are equity-linked derivatives. As such, we recognize these instruments as off-balance sheet arrangements. The conversion features associated with these notes would be accounted for as derivative instruments, except that they are indexed to our common stock and classified in stockholders' equity. Therefore, these instruments meet the scope of exception of paragraph 11(a) of SFAS No. 133, "Accounting for Derivatives Instruments and Hedging Activities," and are accordingly not accounted for as derivatives for purposes of SFAS No. 133.

Recent Accounting Pronouncements

        The FASB has issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes, an interpretation of SFAS No. 109" ("FIN 48"), which clarifies the accounting for uncertainty in income taxes. Prior to the effective date of FIN 48, the accounting for uncertainty in income taxes was subject to significant and varied interpretations that have resulted in diverse and inconsistent accounting practices and measurements. Addressing such diversity, FIN 48 prescribes a consistent recognition threshold and measurement attribute, as well as clear criteria for subsequently recognizing, derecognizing and measuring changes in such tax positions for financial statement purposes. FIN 48 also requires expanded disclosure with respect to the uncertainty in income taxes. FIN 48 is effective for fiscal years beginning after December 15, 2006. We adopted the provisions of FIN 48 effective December 31, 2006 which did not have a significant impact on its consolidated financial results.

        We adopted the recognition and disclosure requirements of 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)" ("SFAS 158") as of December 30, 2006. SFAS 158 includes two phases of implementation. The second phase of SFAS 158 requires that the valuation date of plan accounts be as of the end of the fiscal year, with that change required to be implemented by fiscal years ending after December 15, 2008. We have changed the valuation date relating to foreign plans which did not have a material impact on our consolidated financial statements.

        The FASB issued SFAS No. 157, Fair Value Measurements ("SFAS 157"). SFAS 157 establishes a single authoritative definition of fair value, sets a framework for measuring fair value and expands on required disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007 and will be applied prospectively. In February 2008, the FASB issued a Staff Position that will (1) partially defer the effective date of SFAS 157 for one year for certain nonfinancial assets and nonfinancial liabilities and (2) remove certain leasing transactions from the scope of SFAS 157. The provisions of SFAS 157 are not expected to have a material impact on the our consolidated financial statements.

        The FASB issued SFAS No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities—Including an amendment of FASB Statement No. 115" ("SFAS 159"). SFAS 159 allows companies to elect to follow fair value accounting for certain financial assets and liabilities in an effort to mitigate volatility in earnings without having to apply complex hedge accounting provisions. SFAS 159 is applicable only to certain financial instruments and is effective for fiscal years beginning after November 15, 2007. The provisions of SFAS 159 are not expected to have a material impact on our consolidated financial statements.

        The FASB issued SFAS No. 141(R), Business Combinations ("SFAS 141(R)") and No. 160, Noncontrolling Interests in Consolidated Financial Statements ("SFAS 160"). SFAS 141(R) and SFAS 160 introduce significant changes in the accounting for and reporting of business acquisitions and noncontrolling interests in a subsidiary. SFAS 141(R) continues the movement toward the greater use of fair values in financial reporting and increased transparency through expanded disclosures. SFAS 141(R) changes how business acquisitions are accounted for and will impact financial statements at the acquisition date and in subsequent periods. In addition, SFAS 141(R) will impact the annual goodwill impairment test associated with acquisitions that close both before and after its effective date. SFAS 141(R) applies prospectively to fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008. An entity may not apply SFAS 141(R) before that date. We are evaluating the impact of adopting the provisions of SFAS 141(R) and SFAS 160 on our financial position and results of operations.

Item 7A.    Quantitative and Qualitative Disclosure About Market Risk

        Certain of our financial instruments are subject to market risks, including interest rate risk and foreign currency exchange rates. We generally do not use financial instruments for trading or other speculative purposes.

Interest Rate Risk

        The fair value of our marketable securities is subject to interest rate risk and will fall in value if market interest rates increase. If market rates were to increase immediately and uniformly by 100 basis points from levels at December 29, 2007, then the fair value of the portfolio would decline by approximately $0.4 million.

        We have entered into two credit agreements, the $428 million credit agreement (prior to July 31, 2006, the $660 million credit agreement) and the $50 million credit agreement. Our primary interest rate exposure results from changes in LIBOR or the base rates which are used to determine the applicable interest rates under our term loans in the $428 million credit agreement and in the $50 million agreement and our revolving credit facilities. Our potential additional interest expense over one year that would result from a hypothetical, instantaneous and unfavorable change of 100 basis points in the interest rate would be approximately $3.8 million on a pre-tax basis. The book value of our debt approximates fair value.

        We issued $350 million of the 2013 Notes in a private placement in the second quarter of 2006. The convertible senior debenture notes bear an interest rate of 2.25%. The fair market value of the outstanding notes was $514.5 million on December 29, 2007.

Foreign Currency Exchange Rate Risk

        We operate on a global basis and have exposure to some foreign currency exchange rate fluctuations for our earnings and cash flows. This risk is mitigated by the fact that various foreign operations are principally conducted in their respective local currencies. However, a portion of our foreign operations' revenue is denominated in U.S. dollars, with the costs accounted for in their local currencies. We attempt to minimize this exposure by using certain financial instruments, for purposes other than trading, in accordance with our overall risk management and our hedge policy. In accordance with our hedge policy, we designate certain transactions as hedges as set forth in SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities."

        During 2007, we utilized foreign exchange contracts, principally to hedge the impact of currency fluctuations on customer transactions and certain balance sheet items. No foreign exchange contracts were outstanding on December 29, 2007.

Report of Management

Management's Report on Internal Control Over Financial Reporting

        The management of the company is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) or 15(d)-15(f) promulgated under the Securities Exchange Act of 1934 as a process designed by, or under the supervision of, the company's principal executive and principal financial officers and effected by the company's board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with United States generally accepted accounting principles and includes those policies and procedures that:


        Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper management override. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk.

        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.

        The Company's management assessed the effectiveness of the company's internal control over financial reporting as of December 29, 2007. In making this assessment, the company's management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework.

        Based on this assessment, management concluded that, as of December 29, 2007, the Company's internal control over financial reporting was effective based on those criteria.

        Our internal control over financial reporting as of December 29, 2007 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated within their report which appears herein.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Charles River Laboratories International, Inc.:

        In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of Charles River Laboratories International, Inc. and its subsidiaries at December 29, 2007 and December 30, 2006, and the results of their operations and their cash flows for each of the three years in the period ended December 29, 2007 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 29, 2007, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements and for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control Over Financial Reporting appearing under Item 8. Our responsibility is to express opinions on these financial statements and on the Company's internal control over financial reporting based on our integrated 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 audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

        As discussed in Note 9 to the consolidated financial statements, the Company changed its method of accounting for share-based payments on January 1, 2006. Also as discussed in Note 8 to the consolidated financial statements, the Company changed its method of accounting for defined benefit pension and other post retirement obligations as of December 30, 2006. In addition, as discussed in Note 7 to the consolidated financial statements, the Company changed its method of accounting for uncertain tax positions as of January 1, 2007.

        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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) 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 (iii) 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(dollars in thousands, except per share amounts)

1. Description of Business and Summary of Significant Accounting Policies

        Charles River Laboratories International, Inc. (together with its subsidiaries, the Company) is a leading global provider of solutions that accelerate the drug discovery and development process including research models and associated services, and outsourced preclinical services. The Company's fiscal year is the twelve-month period ending the last Saturday in December.

        The consolidated financial statements include all majority-owned subsidiaries. Intercompany accounts, transactions and profits are eliminated. Results for two majority-owned subsidiaries are recorded on a one-month lag basis. There were no material transactions or events for these subsidiaries between the reporting date and December 29, 2007.

        Certain reclassifications have been made to prior year statements to conform to the current year presentation. These reclassifications have no impact on period reported net income or cash flow.

        The financial statements have been prepared in conformity with generally accepted accounting principles and, as such, include amounts based on informed estimates and judgments of management with consideration given to materiality. Actual results could differ from those estimates.

        Cash equivalents include time deposits and highly liquid investments with remaining maturities at the purchase date of three months or less.

        The Company records trade receivables net of an allowance for doubtful accounts. The Company establishes an allowance for doubtful accounts which it believes is adequate to cover anticipated losses on the collection of all outstanding trade receivable balances. The adequacy of the doubtful account allowance is based on historical information, a review of major customer accounts receivable balances and management's assessment of current economic conditions. The Company reassesses the allowance for doubtful accounts each quarter. Provisions to the allowance for doubtful accounts amount to $494 in 2007 and $928 in 2006. Write offs to the allowance for doubtful accounts amounted to $421 in 2007 and $98 in 2006.

1. Description of Business and Summary of Significant Accounting Policies (Continued)

        The composition of net trade receivables is as follows:

 
  December 29,
2007

  December 30,
2006

 
Customer receivables   $ 165,057   $ 156,411  
Unbilled revenue     52,033     49,356  
   
 
 
Total     217,090     205,767  
Less allowance for doubtful accounts     (3,182 )   (3,109 )
   
 
 
  Net trade receivables   $ 213,908   $ 202,658  
   
 
 

        Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of trade receivables from customers in the pharmaceutical and biotechnology industries. The Company believes its exposure to credit risk to be minimal, as these industries have experienced significant growth and the customers are predominantly well established and viable.

        The Company accounts for its investment in marketable securities in accordance with Statement of Financial Accounting Standards ("SFAS") No. 115, "Accounting for Certain Investments in Debt and Equity Securities." Investments in marketable securities are reported at fair value and consist of corporate debt securities and government securities and obligations which are classified as securities available for sale and mutual funds which are classified as actively traded.

        Realized gains and losses on securities are included in earnings and are determined using the specific identification method. Unrealized holding gains and losses on securities classified as available for sale, are excluded from earnings and are reported in accumulated other comprehensive income, net of related tax effects. Unrealized gains and losses on actively traded securities are included in earnings. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion is included in interest income.

        As of December 29, 2007, the Company held $38,175 in auction rate securities which are variable rate debt instruments, which bear interest rates that reset approximately every 35 days. The auction rate securities owned by the Company were rated AAA by a major credit rating agency and are either commercially insured or guaranteed by the Federal Family Education Loan Program (FFELP). The underlying securities have contractual maturities which are generally greater than ten years. The auction rate securities are classified as available for sale and are recorded at fair value. Typically, the carrying value of auction rate securities approximates fair value due to the frequent resetting of the interest rates. The Company has classified these investments as long-term consistent with the term of the underlying security which are structured with short term interest rate reset dates of generally 35 days but with contractual maturities that are long term.

        Inventories are stated at the lower of cost, determined principally on the average cost method, or market. The determination of market value involves assessment of numerous factors, including costs to dispose of inventory and estimated selling price. Inventory costs for small models are based upon the average cost to produce specific models and strains. Costs for large models are accumulated in

inventory by specific model. Inventory costs for both small and large models are charged to cost of sales in the period the models are sold. Reserves are recorded to reduce the carrying value for inventory determined damaged, obsolete or otherwise unsaleable.

        The composition of inventories is as follows:

 
  December 29,
2007

  December 30,
2006

Raw materials and supplies   $ 13,139   $ 11,715
Work in process     9,794     6,107
Finished products     65,090     54,540
   
 
  Inventories   $ 88,023   $ 72,362
   
 

        Other current assets consist of assets the Company intends to settle within the next twelve months.

 
  December 29,

Prepaid assets   $ 26,087   $ 19,686

Marketable securities     14,958     7,450
Prepaid income tax     7,214     7,051
Restricted cash     3,493    
Other     2,219    
   
 
  Other current assets   $ 79,477   $ 44,363
   
 

        Property, plant and equipment, including improvements that significantly add to productive capacity or extend useful life, are recorded at cost, while maintenance and repairs are expensed as incurred. The Company capitalizes interest and period costs on certain capital projects which amounted to $4,716 and $5,484 in 2007, $4,107 and $2,904 in 2006 and $810 and $191 in 2005, respectively. The Company also capitalizes internal and external cost incurred during the application development stage of internal use software. Depreciation is calculated for financial reporting purposes using the straight-line method based on the estimated useful lives of the assets as follows: buildings, 20 to 40 years; machinery and equipment, 3 to 20 years; furniture and fixtures, 5 to 10 years; vehicles, 3 to 5 years; and leasehold improvements, the shorter of estimated useful life or the lease periods. The Company begins to depreciate capital projects in the first full month the asset is placed in service.

        Depreciation expense for 2007, 2006 and 2005 was $52,870, $44,947 and $40,924, respectively.

        The Company accounts for goodwill and other intangible assets in accordance with SFAS No. 142, "Goodwill and Other Intangible Assets," which establishes financial accounting and reporting standards for acquired goodwill and other intangible assets. SFAS No. 142 requires that goodwill and indefinite-lived intangible assets are no longer amortized but are reviewed at least annually for impairment. Separate intangible assets that have finite useful lives continue to be amortized over their estimated useful lives.

        The Company tests goodwill for impairment annually or whenever events or circumstances occur as required under the provisions of SFAS No. 142. Goodwill is considered to be impaired when the net book value of a reporting unit exceeds its estimated fair value. During 2007, the Company performed its annual impairment test of goodwill and concluded there was no impairment. As a result of the decision to divest the Phase II-IV Clinical business in the first quarter of 2006, the Company preformed a goodwill impairment test assuming sale of the Phase II-IV Clinical business and recorded a goodwill impairment charge of $129,187 in discontinued operations. For the Company's remaining goodwill, an annual impairment test was performed for 2006 and concluded there was no additional goodwill impairment.

        Intangible assets deemed to have an indefinite life are tested for impairment using a one-step process which compares the fair value to the carrying amount of the asset. The Company completed the annual impairment tests in 2007 and 2006 and concluded there was no impairment of identifiable intangible assets with indefinite useful lives.

        Other assets consist of assets that the Company does not intend to settle within the next twelve months.

        The Company accounts for its investments in life insurance contracts in accordance with FASB Staff Position No. FTB 85-4, Accounting for Life Settlement Contracts by Third-Party Investors using the fair value method. Under the fair value method, the Company recognizes the initial investment at the transaction price and remeasures the investment at fair value each reporting period. Investments in life contracts are reported as part of purchases of marketable securities in the statement of cash flows. At December 29, 2007, the Company held 66 contracts with a carrying value of $22,027 and a face value of $128,812.

        In accordance with SFAS No. 144, "Accounting for the Impairment or Disposal of Long-lived Assets," the Company evaluates long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss may be recognized when estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposal are less than its carrying amount. In such instances, additional analysis is performed and the carrying value of long-lived assets is reduced to the estimated fair value, if this is lower, as determined using an appraisal or discounted cash flows, as appropriate.

        During 2007, the Company closed its Worcester, MA facility and recorded an impairment charge of $2,970 to reduce the value to the estimated fair value. The building has been classified as held for sale and is included in other current asset on the consolidated balance sheet.

        The Company recognizes obligations associated with restructuring activities and contract termination costs in accordance with SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities." SFAS 146 requires a liability at fair value for the costs associated with an exit or disposal activity as well as costs to terminate a contract or an operating lease. The overall purpose of the Company's restructuring actions is to lower overall operating costs and improve profitability by reducing excess capacities. Restructuring charges are typically recorded in selling, general and administrative expenses in the period in which the plan is approved by the Company's senior management and, where material, the Company's Board of Directors, and when the liability is incurred. A liability for costs that will continue to be incurred under a contract for its remaining term without economic benefit to the entity is recognized and measured at its fair value when the entity ceases using the right conveyed by the contract.

        Prior to January 1, 2006, the Company had followed Accounting Principles Board ("APB") Opinion 25, "Accounting for Stock Issued to Employees" and related interpretations, which resulted in accounting for grants and awards to employees at their intrinsic value in the consolidated financial statements. On January 1, 2006, the Company adopted SFAS No. 123(R) ("SFAS No. 123(R)"), "Accounting for Stock-Based Compensation," using the modified prospective application transition method, which results in the provisions of SFAS No. 123(R) being applied to the consolidated financial statements on a going-forward basis. Prior periods have not been restated. Under SFAS No. 123(R), the Company is required to record compensation cost for all share-based payments granted after the date of adoption based on the grant date fair value, estimated in accordance with the provisions of SFAS 123(R), and for the unvested portion of all share-based payments previously granted that remain outstanding based on the grant date fair value, estimated in accordance with the original provisions of SFAS 123. The estimated fair value of the Company's stock-based awards is expensed on a straight-line basis over the service period.

        The Company recognizes revenue related to its products and services in accordance with the SEC Staff Accounting Bulletin (SAB) No. 104, "Revenue Recognition."

        The Company recognizes revenue related to its products, which include research models, in vitro technology and vaccine support products, when persuasive evidence of an arrangement exists, generally in the form of customer purchase orders, title and risk of loss have transferred, which occurs upon delivery of the products, the sales price is fixed and determinable and collectibility is reasonably assured. These recognition criteria are met at the time the product is delivered to the customer's site. Product sales are recorded net of returns upon delivery. For large models in some cases customers pay in advance of delivery of the product. These advances are deferred and recognized as revenue upon delivery of the product.

        The Company's service revenue is comprised of toxicology, pathology, laboratory, clinical Phase I trials, transgenic and contract staffing services and is generally evidenced by customer contracts. Toxicology services provide highly specialized studies to evaluate the safety and toxicity of new pharmaceutical compounds and materials used in medical devices. Pathology services provide the ability to identify and characterize pathologic changes within tissues and cells in determining the safety of a new compound. Laboratory services monitor and analyze the health and genetics of research models used in research protocols. Clinical Phase I conducts tolerability assessments to explore human pharmacology. Transgenic services include validating, maintaining, breeding and testing research models for biomedical research activities. Contract staffing services provide management of animal care operations on behalf of government, academic, pharmaceutical and biotechnology organizations.

        The toxicology, pathology and clinical Phase I trials services arrangements typically range from one to six months but can range up to approximately 24 months in length. These agreements are negotiated for a fixed fee. Laboratory service arrangements are generally completed within a one-month period and are also of a fixed fee nature. Transgenic and contract staffing services are of a longer-term nature, from six months to five years, and are billed at agreed upon rates as specified in the contract.

        The Company's service revenues are recognized upon the Company's completion of the agreed upon performance criteria. These performance criteria are generally in the form of either study protocols or specified activities or procedures which the Company is engaged to perform. These performance criteria are established by the Company's customers and do not contain acceptance provisions which are based upon the achievement of certain study or laboratory testing results. Revenue of agreed upon rate contracts is recognized as services are performed, based upon rates specified in the contract. Revenue of fixed fee contracts is recognized as services are performed in relation to estimated costs to complete procedures specified by customers in the form of study protocols.

        Deferred and unbilled revenue is recognized in the consolidated balance sheets. In some cases, a portion of the contract fee is paid at the time the study is initiated. These advances are deferred and recognized as revenue as services are performed. Revenue is recognized on unbilled services and relate to amounts that are currently unbillable to the customer pursuant to contractual terms. In general, such amounts become billable in accordance with predetermined payment schedules, but are recognized as revenue as services are performed.

        The Company includes standard indemnification provisions in its customer contracts, which include standard provisions limiting the Company's liability under such contracts, including the Company's indemnification obligations, with certain exceptions.

        The Company follows the requirements of SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities," which establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts and used for hedging activities. All derivatives, whether designed for hedging relationships or not, are required to be recorded on the balance sheet at fair value. If the derivative is designated as a fair value hedge, all changes in the fair value of the derivative and changes in the fair value of the hedged item attributable to the hedged risk are recognized in earnings. If the derivative is designated as a cash flow hedge, the effective portion of the changes in the fair value of the derivative are recorded in other comprehensive income and are recognized in the statement of operations when the hedged item affects earnings. The ineffective portions of both fair value and cash flow hedges are immediately recognized as earnings. The Company recorded a hedge gain (loss) of $1,603 in 2007, $(66) in 2006 and $337 in 2005.

        The carrying amounts of the Company's significant financial instruments, which include cash equivalents, marketable securities, accounts receivable and accounts payable, approximate their fair values at December 29, 2007 and December 30, 2006. The fair value of the Company's financing instruments was $514,500 and $572,054 based on market rates at December 29, 2007 and December 30 2006 respectively.

        The Company accounts for income taxes in accordance with SFAS No. 109, "Accounting for Income Taxes." The asset and liability approach underlying SFAS No. 109 requires the recognition of deferred tax liabilities and assets for the expected future tax consequences of temporary differences between the carrying amounts and tax basis of the Company's assets and liabilities. A valuation allowance is provided for deferred tax assets if it is more likely than not that these items will expire before the Company is able to realize their benefits or that their future deductibility is uncertain.

        Effective December 31, 2006, the Company adopted the provisions of FIN 48 "Accounting for Uncertainty in Income Taxes-an interpretation of FASB Statement No. 109," which clarifies the accounting for income tax positions by prescribing a minimum recognition threshold that a tax position is required to meet before being recognized in the financial statements. FIN 48 also provides guidance on the derecognition of previously recognized income tax items, measurement, classification, interest and penalties, accounting in interim periods and financial statement disclosure. Under FIN 48, the Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities, based on the technical merits of the tax position. The tax benefits recognized in our financial statements from such positions are measured on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution.

        The functional currencies of the Company's operating foreign subsidiaries are in local currency. In accordance with SFAS No. 52, "Foreign Currency Translation," the financial statements of these subsidiaries are translated into U.S. dollars as follows: assets and liabilities at year-end exchange rates; income, expenses and cash flows at average exchange rates; and shareholders' equity at historical exchange rates. The resulting translation adjustment is recorded as a component of accumulated other comprehensive income in the accompanying balance sheet. Exchange gains and losses on foreign currency transactions are recorded as other income or expense. The Company recorded an exchange gain (loss) of $(3,959) in 2007, $170 in 2006 and $(1,024) in 2005.

        The Company accounts for comprehensive income in accordance with SFAS No. 130, "Reporting Comprehensive Income." As it relates to the Company, comprehensive income is defined as net income plus the sum of the changes in unrealized gains (losses) on available-for-sale marketable securities, unrealized gains (losses) on hedging activities, foreign currency translation adjustments and amortization of unrecognized pension gains and losses and prior service costs and credits (collectively, other comprehensive income) and is presented in the Consolidated Statements of Changes in Shareholders' Equity, net of tax.

        The Company recognizes obligations associated with its defined benefit pension plans in accordance with SFAS No. 87, "Employers Accounting for Pensions." Assets, liabilities and expenses are calculated by accredited independent actuaries. As required by SFAS No. 87, the Company is required to make certain assumptions to value the plan assets and liabilities. These assumptions are reviewed annually, or whenever otherwise required by SFAS No. 87, based on reviews of current plan information and consultations with independent investment advisors and actuaries. The selection of assumptions requires a high degree of judgment and may materially change from period to period. The Company does not offer other defined benefits associated with post-retirement benefit plans other than pensions.

        The Company adopted the recognition and disclosure requirements of 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)" as of December 30, 2006. This statement requires employers that sponsor defined benefit plans to recognize the funded status of a benefit plan on its balance sheet; recognize gains, losses and prior service costs or credits that arise during the period that are not recognized as components of net periodic benefit cost as a component of accumulated other comprehensive income, net of tax; measure defined benefit plan assets and obligations as of the date of the employer's fiscal year-end balance sheet; and disclose in the notes to financial statements additional information about certain effects on net periodic benefit cost for the next fiscal year that arise from delayed recognition of the gains or losses, prior service costs or credits, and transition asset or obligation.

        Basic earnings per share are calculated by dividing net income by the weighted average number of common shares outstanding. Diluted earnings per common share are calculated by adjusting the weighted average number of common shares outstanding to include the number of additional common shares that would have been outstanding if the dilutive potential common shares had been issued.

        In accordance with SFAS No. 144, the results of discontinued operations, less applicable income taxes (benefit), are reported as a separate component in the accompanying statement of income for the current and prior periods. The statement of cash flows also reflects separate disclosure of cash flows pertaining to discontinued operations consistently for all periods presented.

        The FASB has issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes, an interpretation of SFAS No. 109" ("FIN 48"), which clarifies the accounting for uncertainty in income taxes. Prior to the effective date of FIN 48, the accounting for uncertainty in income taxes was subject to significant and varied interpretations that have resulted in diverse and inconsistent accounting practices and measurements. Addressing such diversity, FIN 48 prescribes a consistent recognition threshold and measurement attribute, as well as clear criteria for subsequently recognizing, derecognizing and measuring changes in such tax positions for financial statement purposes. FIN 48 also requires expanded disclosure with respect to the uncertainty in income taxes. FIN 48 is effective for fiscal years beginning after December 15, 2006. The Company adopted the provisions of FIN 48 effective December 31, 2006 which did not have a significant impact on its consolidated financial results.

        The Company adopted the recognition and disclosure requirements of 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)" ("SFAS 158") as of December 30, 2006. SFAS 158 includes two phases of implementation. The second phase of SFAS 158 requires that the valuation date of plan accounts be as of the end of the fiscal year, with that change required to be implemented by fiscal years ending after December 15, 2008. The Company will change the valuation date relating to its foreign plans which will not have a material impact on the Company's consolidated financial statements.

        The FASB issued SFAS No. 157, Fair Value Measurements ("SFAS 157"). SFAS 157 establishes a single authoritative definition of fair value, sets out framework for measuring fair value and expands on required disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007 and will be applied prospectively. In February 2008, the FASB issued a Staff Position that will (1) partially defer the effective date of SFAS 157 for one year for certain nonfinancial assets and nonfinancial liabilities and (2) remove certain leasing transactions from the scope of SFAS 157. The provisions of SFAS 157 are not expected to have a material impact on the Company's consolidated financial statements.

        The FASB issued SFAS No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities—Including an amendment of FASB Statement No. 115" ("SFAS 159"). SFAS 159 allows companies to elect to follow fair value accounting for certain financial assets and liabilities in an effort

to mitigate volatility in earnings without having to apply complex hedge accounting provisions. SFAS 159 is applicable only to certain financial instruments and is effective for fiscal years beginning after November 15, 2007. The provisions of SFAS 159 are not expected to have a material impact on the Company's consolidated financial statements.

        The FASB issued SFAS No. 141(R), Business Combinations ("SFAS 141(R)") and No. 160, Noncontrolling Interests in Consolidated Financial Statements ("SFAS 160"). SFAS 141(R) and SFAS 160 introduce significant changes in the accounting for and reporting of business acquisitions and noncontrolling interests in a subsidiary. SFAS 141(R) continues the movement toward the greater use of fair values in financial reporting and increased transparency through expanded disclosures. SFAS 141(R) changes how business acquisitions are accounted for and will impact financial statements at the acquisition date and in subsequent periods. In addition, SFAS 141(R) will impact the annual goodwill impairment test associated with acquisitions that close both before and after its effective date. SFAS 141(R) applies prospectively to fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008. An entity may not apply SFAS 141(R)before that date. The Company is evaluating the impact of adopting the provisions of SFAS 141(R) and SFAS 160 on our financial position and results of operations.

2. Business Acquisitions

        The Company acquired several businesses during the three-year period ended December 29, 2007. The results of operations of the acquired businesses are included in the accompanying consolidated financial statements from the date of acquisition. Significant acquisitions include the following:

        On June 14, 2007, the Company entered into a joint venture with Shanghai BioExplorer Co., Ltd., a Shanghai, China-based provider of preclinical services, to form Charles River Laboratories Preclinical Services—China. The Company paid $2,400 in cash for a 75% ownership interest in the joint venture. Additionally, as part of the agreement, the joint venture purchased the net assets of Shanghai BioExplorer for a purchase price of $1,532 including transaction costs of $543. Intangible assets of $935 were recorded by the joint venture based on the preliminary purchase price allocation.

5. Long-Term Debt

        On July 31, 2006, the Company amended and restated its $660,000 credit agreement to reduce the current interest rate, modify certain restrictive covenants and extend the term. The amount of debt outstanding under the original $660,000 credit agreement remained the same at the time of amendment. The now $428,000 credit agreement provided for a $156,000 U.S. term loan facility, a $200,000 U.S. revolving facility, a C$57,800 term loan facility and a C$12,000 revolving facility for a Canadian subsidiary, and a GBP 6,000 revolving facility for a U.K. subsidiary. The $156,000 term loan facility matures in 20 quarterly installments with the last installment due June 30, 2011. As of December 29, 2007, the Company had $109,200 outstanding on the U.S. term loan. The $200,000 U.S. revolving facility matures on July 31, 2011 and requires no scheduled payment before that date. Under specified circumstances, the $200,000 U.S. revolving facility may be increased by $100,000. The Canadian term loan was repaid during 2007. The Canadian and U.K. revolving facilities mature on July 31, 2011 and require no scheduled prepayment before that date. The interest rate applicable to the Canadian term loan and the Canadian and U.K. revolving loans under the credit agreement is the adjusted LIBOR rate in its relevant currency plus an interest rate margin based upon the Company's leverage ratio. The interest rates applicable to term loans and revolving loans under the credit agreement are, at the Company's option, equal to either the base rate (which is the higher of the prime

5. Long-Term Debt (Continued)

rate or the federal funds rate plus 0.50%) or the adjusted LIBOR rate plus an interest rate margin based upon the Company's leverage ratio. Based on the Company's leverage ratio, the margin range for LIBOR based loans is 0.625% to 0.875%. The interest rate margin was 0.75% as of December 29, 2007. The Company has pledged the stock of certain subsidiaries as well as certain U.S. assets as security for the $428,000 credit agreement. The $428,000 credit agreement includes certain customary representations and warranties, events of default and negative and affirmative covenants including the ratio of consolidated earnings before interest, taxes, depreciation and amortization ("EBITDA") to consolidated interest expense, for any period of four consecutive fiscal quarters, of no less than 3.5 to 1.0. The Company had $5,466 and $5,388 outstanding under letters of credit as of December 29, 2007 and December 30, 2006, respectively. During 2007, the Company did not borrow under its revolving credit facilities. As of December 29, 2007, there were no outstanding balances on the revolving facilities.

        On July 27, 2005 the Company entered into a $50,000 credit agreement ("$50,000 credit agreement"), which was subsequently amended on December 20, 2005 and again on July 31, 2006 to reflect substantially the same modifications made to the covenants in the $660,000 and $428,000 credit agreements, respectively. On June 15, 2007, the Company executed a third amendment to the $50,000 credit agreement to extend the maturity date and reduce the interest rate. The $50,000 credit agreement provides for a $50,000 term loan facility which matures on June 22, 2010. Prior to the amendment, the interest rate applicable to term loans under the credit agreement was, at the Company's option, equal to either the base rate (which was the higher of the prime rate or the federal funds rate plus 0.50%) or the LIBOR rate plus 0.75%. From June 15, 2007 through June 21, 2008, the interest rates applicable to term loans under the credit agreement are, at the Company's option, equal to either the base rate (which is the higher of the prime rate or the federal funds rate plus 0.50%) minus 2.25% or the LIBOR rate plus 0.50%. Commencing June 22, 2008 through June 22, 2010, the applicable interest rates are equal to either the base rate (which is the higher of the prime rate or the federal funds rate plus 0.50%) or the adjusted LIBOR rate plus an interest rate margin based on the Company's leverage ratio. The $50,000 credit agreement includes certain customary representations and warranties, negative and affirmative covenants and events of default. As of December 29, 2007, the entire balance of the $50,000 credit agreement was outstanding.

        On June 12, 2006, the Company issued $300,000 aggregate principal amount of convertible senior notes ("the 2013 Notes") in a private placement with net proceeds to the Company of approximately $294,000. On June 20, 2006, the initial purchasers associated with this convertible debt offering exercised an option to purchase an additional $50,000 of the 2013 Notes for additional net proceeds to the Company of approximately $49,000. The 2013 Notes bear interest at 2.25% per annum, payable semi-annually, and mature on June 15, 2013. The 2013 Notes are convertible into cash and shares of the Company's common stock (or, at the Company's election, cash in lieu of some or all of such common stock), if any, based on an initial conversion rate, subject to adjustment, of 20.4337 shares of the Company's common stock per $1,000 principal amount of notes (which represents an initial conversion price of $48.94 per share), only in the following circumstances and to the following extent: (i) during any fiscal quarter beginning after July 1, 2006 (and only during such fiscal quarter), if the last reported sale price of the Company's common stock for at least 20 trading days in the period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter is more than 130% of the conversion price on the last day of such preceding fiscal quarter; (ii) during the five business-day period after any five consecutive trading-day period, or the measurement period, in which the trading price per note for each day of that measurement period was less than 98% of the

product of the last reported sale price of the Company's common stock and the conversion rate on each such day; (iii) upon the occurrence of specified corporate transactions, as described in the indenture for the 2013 Notes; and (iv) at the option of the holder at any time beginning on the date that is two months prior to the stated maturity date and ending on the close of business on the second trading-day immediately preceding the maturity date. Upon conversion, the Company will pay cash and shares of its common stock (or, at its election, cash in lieu of some or all of such common stock), if any. As of December 29, 2007, no conversion triggers were met. If the Company undergoes a fundamental change as described in the indenture for the 2013 Notes, holders will have the option to require the Company to purchase all or any portion of their notes for cash at a price equal to 100% of the principal amount of the notes to be purchased plus any accrued and unpaid interest, including any additional interest to, but excluding, the purchase date. The related debt issuance costs of $7,000 were deferred and are being amortized on a straight-line basis over a seven-year term.

        Concurrently with the sale of the 2013 Notes, the Company entered into convertible note hedge transactions with respect to its obligation to deliver common stock under the notes. The convertible note hedges give the Company the right to receive, for no additional consideration, the number of shares of common stock that it is obligated to deliver upon conversion of the notes (subject to anti-dilution adjustments substantially identical to those in the 2013 Notes), and expire on June 15, 2013. The aggregate cost of these convertible note hedges was $98,293.

        Separately and concurrently with the pricing of the 2013 Notes, the Company issued warrants for approximately 7.2 million shares of its common stock. The warrants give the holders the right to receive, for no additional consideration, cash or shares (at the option of the Company) with a value equal to the appreciation in the price of the Company's shares above $59.925, and expire between September 13, 2013 and January 22, 2014 over 90 equal increments. The total proceeds from the issuance of the warrants were $65,423.

        In accordance with Emerging Issues Task Force Issue ("EITF") No. 00-19, "Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company's Own Stock" ("EITF No. 00-19"), SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities" and SFAS No. 150, "Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity," the Company recorded both the purchase of the convertible note hedges and the sale of the warrants as adjustments to additional paid in capital, and will not recognize subsequent changes in fair value of the agreement. At December 29, 2007, the fair value of the outstanding 2013 Notes was approximately $514,500, based on their quoted market value.

6. Shareholders' Equity

        Basic earnings per share for 2007, 2006 and 2005 was computed by dividing earnings available to common shareholders for these periods by the weighted average number of common shares outstanding in the respective periods adjusted for contingently issuable shares. The weighted average number of common shares outstanding for 2007, 2006 and 2005 have been adjusted to include common stock equivalents for the purpose of calculating diluted earnings per share for these periods.

        Options to purchase 243,357 shares, 2,972,420 shares and 2,027,666 shares were outstanding at December 29, 2007, December 30, 2006 and December 31, 2005, respectively, but were not included in computing diluted earnings per share because their inclusion would have been anti-dilutive.

        Basic weighted average shares outstanding for 2005 excluded the weighted average impact of 20,000 shares of contingently issuable shares. In addition, weighted average shares outstanding for 2007, 2006 and 2005 excluded the weighted average impact of 711,896, 653,780 and 544,863 shares, respectively, of non-vested fixed restricted stock awards.

        The sum of the earnings per share from continuing operations and the earnings (loss) per share from discontinued operations does not necessarily equal the earnings (loss) per share from net income in the condensed consolidated statements of operations due to rounding.

        The Board of Directors of the Company has authorized a share repurchase program, originally authorized on July 27, 2005 and subsequently amended on October 26, 2005, May 9, 2006 and August 1, 2007, to acquire up to a total of $400,000 of common stock. The program does not have a fixed expiration date. In order to facilitate these share repurchases, the Company entered into Rule 10b5-1 Purchase Plans.

        During 2007, 2006 and 2005, the Company repurchased 724,200 shares of common stock for $38,911, 518,800 shares of common stock for $23,322 and 396,000 shares of common stock for $17,485, respectively, under these plans. In addition, concurrent with the sale of the 2013 Notes, the Company used $148,866 of the net proceeds for the purchase of 3,726,300 shares of its common stock.

        During 2006 the Company also entered into an Accelerated Stock Repurchase (ASR) program with a third-party investment bank. In connection with this ASR program, the Company purchased 1,787,706 shares of stock at a cost of $75,000. In conjunction with the ASR, the Company also entered

into a cashless collar with a forward floor price of $37.9576 per share of the Company's common stock (95% of the initial price of $39.9554, the market price of the Company's common stock on August 23, 2006) and a forward cap price of $41.9532 per share of the Company's common stock (105% of the initial price). The final number of shares repurchased under the ASR program was determined by taking the average volume weighted average price of the Company's common stock for 65 trading days starting on August 23, 2006. Since the final share price of $42.6503 was above the cap price of $41.9532, there was no adjustment to the final number of shares repurchased.

        As of December 29, 2007, approximately $96,400 remains authorized for share repurchases.

        Share repurchases during 2007 and 2006 were as follows:

 
  Fiscal Year Ended
 
  December 29, 2007
  December 30, 2006
Number of shares of common stock repurchased     724,200     6,032,806
Total cost of repurchase   $ 38,911   $ 247,203

        Additionally, the Company's 2000 Incentive Plan permits the netting of common stock upon vesting of restricted stock awards in order to satisfy individual tax withholding requirements. During the fiscal year ended December 29, 2007 and December 30, 2006, the Company acquired 71,456 shares for $3,506 and 57,688 shares for $2,755, respectively, as a result of such withholdings.

        The timing and amount of any future repurchases will depend on market conditions and corporate considerations.

        Retained earnings includes approximately $2,000 which is restricted due to statutory requirements in the local jurisdiction of a foreign subsidiary as of December 29, 2007 and December 30, 2006.

6. Shareholders' Equity (Continued)

        Separately and concurrently with the pricing of the 2013 Notes, the Company issued warrants for approximately 7.2 million shares of its common stock. The warrants give the holders the right to receive, for no additional consideration, cash or shares (at the option of the Company) with a value equal to the appreciation in the price of the Company's shares above $59.925, and expire between September 13, 2013 and January 22, 2014 over 90 equal increments. The total proceeds from the issuance of the warrants was $65,423.

        As part of the recapitalization in 1999, the Company issued 150,000 units, each comprised of a $1,000 senior subordinated note and a warrant to purchase 7.6 shares of common stock of the Company for total proceeds of $150,000. The Company allocated the $150,000 offering proceeds between the senior subordinated notes ($147,872) and the warrants ($2,128), based upon the estimated fair value. The portion of the proceeds allocated to the warrants is reflected as capital in excess of par in the accompanying consolidated financial statements. Each warrant entitles the holder, subject to certain conditions, to purchase 7.6 shares of common stock of the Company at an exercise price of $5.19 per share of common stock, subject to adjustment under some circumstances. Upon exercise, the holders of warrants would be entitled to purchase 147,250 and 149,910 shares of common stock of the Company as of December 29, 2007 and December 30, 2006, respectively. The warrants expire on October 1, 2009.

        In the third and fourth quarters of 2007, the Company revalued certain of its deferred tax assets and liabilities for the enactment of U.K., German and Canadian federal income tax rate reductions resulting in a tax benefit of $2,793.

        During 2007, the Company recorded a reduction to income taxes payable for $17,750 from the exercise of stock options and vesting of restricted shares. The benefit of this reduction as well as the tax effect of stock based compensation has been recorded to additional paid in capital for $8,727 and goodwill for $524.

        As of December 29, 2007, the Company has non-U.S. net operating loss carryforwards of approximately $6,732 which will begin to expire in 2016. As a result of the acquisition of Northwest

Kinetics in October of 2006, the Company has a U.S. net operating loss carryforward of $581 which will begin to expire in 2026. The Company has U.S. foreign tax credit carryforwards of $2,684 which will begin to expire in 2015. The Company has Canadian Investment Tax Credit carryforwards of $6,746 as a result of its research and development activity in Montreal, which begin to expire in 2015. The Company has a capital loss carryforward in Canada of $867 and has recorded a valuation allowance of $561 against this asset.

        The Company has fully recognized its deferred tax assets on the belief that it is more likely than not they will be realized except for the Canadian capital loss carryforward for which a valuation allowance has been established. This belief is based on all available evidence including historical operating results, projections of taxable income and tax planning strategies.

        In July 2006, the FASB issued FASB Interpretation No. 48, "Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109" ("FIN 48"), which became effective for the Company on December 31, 2006. The cumulative effect of adopting FIN 48 did not result in a change to the Company's opening retained earnings. At December 29, 2007 the amount recorded for unrecognized income tax benefits was $22,129. The increase from the date of adoption is primarily due to the continuing evaluation of uncertain tax positions conducted in the current period. The amount of unrecognized income tax benefits that, if recognized, would favorably impact the effective tax rate was $7,643 at the date of adoption and $12,500 as of December 29, 2007.

        The Company's unrecognized income tax benefits are as follows:

 
  December 29,
2007

 
Beginning balance, upon adoption as of December 31, 2006   $ 16,896  
Additions:        
  Tax positions for current year     3,612  
  Tax positions for prior years     2,413  
Reductions:        
  Tax positions for current year     (65 )
  Tax positions for prior year     (43 )
  Settlements     (177 )
  Expiration of statute of limitations     (507 )
   
 
Ending balance as of December 29, 2007   $ 22,129  
   
 

        The Company has concluded that it is not reasonably possible that the total amounts of unrecognized tax benefits will significantly change within the next year.

        The Company continues to recognize interest and penalties related to unrecognized income tax benefits in income tax expense. The total amount of accrued interest related to unrecognized income tax benefits as of December 31, 2006 and December 29, 2007 was $617 and $1,753 respectively. The Company has not recorded a provision for penalties associated with uncertain tax positions.

        The Company conducts business operations in a number of tax jurisdictions. As a result, the Company is subject to tax audits on a regular basis including, but not limited to, current examinations by the Internal Revenue Service in the United States and Canada Revenue Agency. In regards to the Internal Revenue Service examinations of the 2004 tax returns of the Company and an acquired

subsidiary, the Company filed its formal protests of proposed income tax adjustments with the Appeals Division on July 2, 2007. The Company does not believe that the ultimate settlement of these proposed adjustments will have a material impact to the financial statements. The Company believes it has appropriately provided for all unrecognized tax benefits. The Company is no longer subject to U.S. and international income tax examinations for years before 2002.

        As of December 29, 2007, earnings of non-U.S. subsidiaries considered to be indefinitely reinvested totaled $349,079. No provision for U.S. income taxes has been provided thereon. Upon distribution of those earnings in the form of dividends or otherwise, the Company would be subject to both U.S. taxes and withholding taxes payable to the various foreign countries. It is not practicable to estimate the amount of additional tax that might be payable on this undistributed foreign income.

        On June 12, 2006, the Company issued $300,000 aggregate principal amount of convertible senior notes ("the 2013 Notes") in a private placement with net proceeds to the Company of approximately $294,000. On June 20, 2006, the initial purchasers associated with this convertible debt offering exercised an option to purchase an additional $50,000 of the 2013 Notes for additional net proceeds to the Company of approximately $49,000. The 2013 Notes bear interest at 2.25% per annum, payable semi-annually, and mature on June 15, 2013. Concurrently with the sale of the 2013 Notes, the Company entered into convertible note hedge transactions with respect to its obligation to deliver common stock under the notes. Separately and concurrently with the pricing of the 2013 Notes, the Company issued warrants for approximately 7.2 million shares of its common stock. The Company has elected to apply the rules of the Integration Regulations under Treas. Reg. 1.1275-6 to treat the 2013 Notes and the associated hedge as synthetic debt instruments and accordingly is deducting the option premium paid for the hedge as original issue discount over the 7 year term. The cash tax benefit of this deduction is recorded to additional paid in capital. A deferred tax asset has been recorded to reflect the future cash tax benefit of the deductions over the term of the 2013 Notes. Also, pursuant to Internal Revenue Code Section 1032, the Company will not recognize any gain or loss for tax purpose with respect to the exercise or lapse of the warrants.

        During the fourth quarter of 2005, the Company repatriated $148,027 of its accumulated foreign earnings in a distribution that qualified under the American Jobs Creation Act of 2004 ("AJCA"). The distribution was primarily from the pre-acquisition foreign earnings of Inveresk. The Company provided for income taxes on substantially all of Inveresk's unremitted foreign earnings at the time of the Inveresk acquisition based on the tax rates in effect at date of the acquisition. As a result, the Company recorded a tax benefit of $24,060 from the impact of the change in tax law on the $148,027 distribution. As part of its plan of distribution, the Company restructured its UK operations in order to distribute the funds in the most tax efficient manner and incurred a non-cash charge of $23,110 related to an increase in the deferred tax liability on the remaining undistributed earnings of Inveresk. In addition, the Company incurred an additional tax of $1,883 on the write-off of deferred tax assets.

        Also during the fourth quarter of 2005, the Company changed its assertion with respect to the remaining unremitted pre-acquisition earnings of Inveresk in order to fund the expansion of the Company's preclinical facilities and an increased UK pension funding requirement. These earnings and the earnings distributed under the AJCA were previously not considered permanently reinvested. The Company recorded a non-cash benefit from the change in assertion of $29,204.

        During the second quarter of 2005, the Company realized a cash tax benefit of $14,497 when it converted all of its $185,000 3.5% senior convertible debentures. Also in 2005, the Company recorded a reduction to income taxes payable for $7,600 from the exercise of stock options. The benefit from both of these items has been recorded to additional paid in capital.

8. Employee Benefits

        The Company's defined contribution plan, the Charles River Laboratories Employee Savings Plan, qualifies under section 401(k) of the Internal Revenue Code. It covers substantially all U.S. employees and contains a provision whereby the Company matches a percentage of employee contributions. The costs associated with this defined contribution plan totaled $4,074, $3,439 and $3,316, in 2007, 2006, and 2005, respectively.

        On February 8, 2006, the Company established the Charles River Laboratories Deferred Compensation Plan (Deferred Compensation Plan) for select eligible employees, including its Named Executive Officers. Under the Deferred Compensation Plan, participants may elect to defer bonus and salary amounts, and may select the investment returns to be applied to deferred amounts from among a number of reference mutual funds as well as an interest crediting rate. The plan is not qualified under Section 401(a) of the Internal Revenue Code and is not subject to the Employee Retirement Income Security Act of 1974. At the present time, no Company contributions will be credited to the plan, except as set forth below. Participants must specify the distribution date for deferred amounts at the time of deferral, in accordance with applicable IRS regulations. Generally, amounts may be paid in lump sum or installments upon retirement or termination of employment, or later if the employee terminates employment after age 55 and before age 65. Amounts may also be distributed during employment, subject to a minimum deferral requirement of three years.

        In addition to the Deferred Compensation Plan, certain officers and key employees of the Company also participate, or in the past participated, in the Company's amended and restated Executive Supplemental Life Insurance Retirement Plan (ESLIRP) which is a non-funded, non-qualified arrangement. Annual benefits under this plan will equal a percentage of the highest five consecutive years of compensation, offset by amounts payable under the Charles River Laboratories, Inc. Pension Plan and Social Security.

        In connection with the establishment of the Deferred Compensation Plan, current active employees who agreed to convert their ESLIRP benefit to a comparable benefit in the deferred compensation plan discontinued their direct participation in the ESLIRP. Instead, the present value of the accrued benefits of ESLIRP participants was credited to their Deferred Compensation Plan accounts, and future ESLIRP accruals will now be converted to present values and credited to their Deferred Compensation Plan accounts annually. Upon the adoption of the Deferred Compensation Plan, the value of their accrued ESLIRP benefits, prior to adjustments for outstanding Medicare taxes, were credited to their Deferred Compensation Plan account. In addition, the Company provides certain active employees an annual contribution into their Deferred Compensation Plan account of 10% of the employee's base salary plus the lesser of their target annual bonus or actual annual bonus. The costs

associated with these defined contribution plans totaled $3,462 and $4,029 in 2007 and 2006, respectively.

        The Company has invested in several corporate-owned key-person life insurance policies as well as mutual funds and U.S. Treasury Securities with the intention of using these investments to fund the ESLIRP and the Deferred Compensation Plan. Participants have no interest in any such investments. At December 29, 2007 and December 30, 2006 the cash surrender value of these life insurance policies were $22,027 and $14,360, respectively. Additionally, at December 29, 2007 and December 30, 2006, mutual fund and U.S. Treasury Securities investments totaled $2,372 and $6,510, respectively.

        The Charles River Laboratories, Inc. Pension Plan (Pension Plan), is a qualified, non-contributory defined benefit plan that covers certain U.S. employees. Benefits are based on participants' final average monthly compensation and years of service. Participants' rights vest upon completion of five years of service. Effective January 1, 2002, the plan was amended to exclude new participants from joining the plan. Benefit criteria offered to existing participants as of the amendment date did not change.

        The defined benefit pension plans for Japan and our Canadian RMS operation are non-contributory plans that cover substantially all employees of those respective companies. Benefits are based upon length of service and final salary. In addition, our French RMS operation has a defined benefit statutory indemnity plan covering most of its employees.

        In connection with the Inveresk acquisition on October 20, 2004, the Company assumed a defined contribution plan and a defined benefit pension plan covering certain employees. Contributions under the defined contribution plan are determined as a percentage of gross salary. As a result of the sale of Phase II-IV of the Clinical business, this plan realized a curtailment of $1,466 during 2006 associated with those employees who participated in this plan and whose employment with the Company was terminated in connection with the sale.

        The Company adopted the recognition and disclosure requirements of 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)" as of December 30, 2006. This statement requires employers that sponsor defined benefit plans to recognize the funded status of a benefit plan on its balance sheet; recognize gains, losses and prior service costs or credits that arise during the period that are not recognized as components of net periodic benefit cost as a component of other comprehensive income, net of tax; measure defined benefit plan assets and obligations as of the date of the employer's fiscal year-end balance sheet; and disclose in the notes to financial statements additional information about certain effects on net periodic benefit cost for the next fiscal year that arise from delayed recognition of the gains or losses, prior service costs or credits, and transition asset or obligation. Retrospective application is not permitted. The following tables summarize the funded status of the Company's defined benefit plans and amounts reflected in the Company's consolidated balance sheets in accordance with SFAS No. 158.
