## PART I

## Item 1. BUSINESS

Laboratory Corporation of America \( ^{®} \)  Holdings and its subsidiaries (the “Company”), headquartered in Burlington, North Carolina, is the second largest independent clinical laboratory company in the United States based on 2014 net revenues. Since the Company’s founding in 1971 as a Delaware corporation, it has grown into a national network of 39 primary laboratories and approximately 1,750 patient service centers (“PSCs”) along with a network of branches and STAT laboratories (which are laboratories that have the ability to perform certain core tests and report the results to the physician quickly). Through its national network of laboratories, the Company offers a broad range of clinical laboratory tests that are used by the medical profession in core testing, patient diagnosis, and in the monitoring and treatment of disease.

With over 36,000 employees worldwide, the Company processes tests on approximately 500,000 patient specimens daily and has laboratory locations throughout the United States and other countries including, Belgium, Canada, China, Japan, Singapore, the United Kingdom and the United Arab Emirates. Its clients include physicians, hospitals, managed care organizations, governmental agencies, employers, pharmaceutical companies and other independent clinical laboratories that do not have the breadth of its testing capabilities. The Company offers a menu of several hundred tests that are frequently used in general patient care by physicians to establish or support a diagnosis, to monitor treatment or to search for an otherwise undiagnosed condition. The most frequently-requested of these tests include blood chemistry analyses, urinalyses, blood cell counts, thyroid tests, Pap tests, Hemoglobin A1C, PSA, STD tests (Ct, Ng, Tv, HIV), HCV tests, Vitamin D, microbiology cultures and procedures, and alcohol and other substance-abuse tests. The Company performs this core group of tests in its major laboratories using sophisticated and computerized instruments, with most results reported within 24 hours. In addition, the Company provides specialty testing services in the areas of allergy, clinical trials, diagnostic genetics, women's health, cardiovascular disease, identity, forensics, infectious disease, endocrinology, oncology, coagulation, occupational testing and pain management.

On November 2, 2014, the Company entered into a definitive merger agreement (“Merger Agreement”) to acquire Covance Inc. (“Covance”) for approximately $6.2 billion in cash and LabCorp common stock, and the acquisition closed on February 19, 2015. Covance is a leading drug development services company providing a wide range of early-stage and late-stage product development services on a worldwide basis primarily to the pharmaceutical and biotechnology industries. Covance also provides laboratory testing services to the chemical, agrochemical and food industries. It has a global network of operations with offices in more than 30 countries and trial activity in more than 100 countries. The Company believes Covance is one of the world’s largest drug development services companies, based on annual net revenues, and one of a few that are capable of providing comprehensive global development services.

Covance’s early development services include preclinical services, such as toxicology, nutritional chemistry and food safety, pharmaceutical chemistry, lead optimization and translational services, and related services, as well as clinical pharmacology services such as first-in-human trials and early patient proof of concept studies. Covance’s late-stage development services include central laboratory services, clinical development services such as Phase II through IV clinical studies, market access services in support of customers’ reimbursement and health care economic consulting needs, and clinical trial support services. Covance’s services are provided across multiple facilities in the United States, Europe and Asia.

With the acquisition of Covance, which will operate as Covance Drug Development, the Company believes it has enhanced the scale and depth of its capabilities as a trusted knowledge partner for stakeholders. The combination expands the Company’s range of diagnostic offerings, and the Company believes that the combined company will deliver faster clinical trial enrollment and drive incremental growth across both the clinical lab and drug development businesses. The transaction is expected to provide the Company with greater scale in the biopharmaceutical research and development market, while creating new and complementary revenue streams, expanding its customer base, and increasing its international presence.

Covance stockholders received 75.76 in cash and 0.2686 shares of the Company's common stock for each share of Covance common stock they owned immediately prior to consummation of the acquisition. Former Covance stockholders own approximately 15.5% of the outstanding shares of the Company's stock following consummation of the transaction.

The description of the Company’s business set forth below generally reflects the operations of the Company prior to the completion of the Covance acquisition, and the discussion of Covance Drug Development below does not cover all of the same matters as are covered for the discussion of the Company’s historical business. References in this Item 1 to the “Company” do not include Covance Drug Development, except where the circumstances clearly indicate otherwise.

## Acquisition of Covance

On February, 19, 2015, the Company completed its acquisition of Covance a leading drug development services company and a leader in nutritional analysis, for approximately $6.2 billion. Covance stockholders received $75.76 in cash and 0.2686 shares of the Company's common stock for each share of Covance common stock they owned immediately prior to the consummation of the acquisition. With the completion of this merger, former Covance stockholders own approximately 15.5% of the outstanding shares of the Company's stock.

In connection with the transaction, the Company initially put in place a $4.25 billion bridge loan, and has since secured permanent financing, including a $1.0 billion 5 year term loan and $2.9 billion in long-term bonds, ranging from 5 years to 30 years. The weighted average interest rate on the $3.9 billion of long-term debt is approximately 3.15%, while the average maturity is approximately 12 years.

Covance, headquartered in Princeton, New Jersey, offers a wide range of early-stage and late-stage drug development services on a worldwide basis primarily to the pharmaceutical and biotechnology industries. The Company believes that the Covance is one of a few providers that are capable of providing comprehensive global drug development services. Covance maintains offices in more than 30 countries.

Covance Drug Development's early development services include 1) preclinical services such as toxicology, nutritional chemistry and food safety, pharmaceutical chemistry, lead optimization and translational services, and related services, as well as 2) clinical pharmacology services such as first-in-human trials and early patient proof of concept studies. These services are provided across multiple facilities in the United States, Europe, Asia and South America.

Covance Drug Development's late-stage development services include 1) central laboratory services, 2) clinical development services such as Phase II through IV clinical studies and periapproval services, 3) market access services in support of customers' reimbursement and health care economic consulting needs, and 4) clinical trial support services. These services are also provided across multiple facilities in the United States, Europe and Asia.

The combination with Covance expands the Company's range of diagnostic offerings, and the Company believes that the combined companies will deliver faster clinical trial enrollment, and drive incremental growth across both the clinical lab and drug development businesses. The transaction will provide LabCorp with greater scale in the biopharmaceutical research and development market, while enabling new sources of revenue, an expanded customer base, and a greater international presence.



## The Clinical Laboratory Testing Industry and Competition

Laboratory tests and procedures are used generally by hospitals, physicians and other health care providers and commercial clients to assist in the diagnosis, evaluation, detection, therapy selection, monitoring and treatment of diseases and other medical conditions through the examination of substances in blood, tissues and other specimens. Clinical laboratory testing is generally categorized as either clinical pathology testing, which is performed on body fluids including blood, or anatomical pathology testing, in which a pathologist examines histologic or cytologic samples (e.g., tissue and other samples, including human cells). Clinical and anatomical pathology procedures are frequently ordered as part of regular physician office visits and hospital admissions in connection with the diagnosis and treatment of illnesses. Certain of these tests and procedures are used in the diagnosis and management of a wide variety of medical conditions such as cancer, infectious disease, endocrine disorders, cardiac disorders and genetic disease. It is estimated that although laboratory services account for less than 3% of total U.S. health care spending (and less than 2% of Medicare expenditures), they influence 60% to 70% of physician medical decisions.

The clinical laboratory industry consists primarily of three types of providers: hospital-based laboratories, physician-office laboratories and independent clinical and anatomical pathology laboratories, such as those operated by the Company. The Company believes that in 2014, the U.S. clinical laboratory testing industry generated revenues of approximately $60.0 billion based on Washington G-2 reports and other industry publications. The Centers for Medicare and Medicaid Services (“CMS”) of the Department of Health and Human Services ("HHS") have estimated that in 2014 there were more than 8,900 hospital-based laboratories, 121,200 physician-office laboratories and 5,900 independent clinical laboratories in the U.S.

The clinical laboratory business is intensely competitive. There are presently two major national independent clinical laboratories: the Company and Quest Diagnostics \( ^{®} \)  Incorporated ("Quest"). Quest had approximately 7.4 billion in revenues in 2014. In addition, the Company competes with laboratories owned by hospitals, many smaller independent laboratories, as well as physician office laboratories. The Company believes that health care providers selecting a laboratory often consider the following factors, among others:

• accuracy, timeliness and consistency in reporting test results;

• reputation of the laboratory in the medical community or field of specialty;

• contractual relationships with managed care companies;

• service capability and convenience offered by the laboratory;

• number and type of tests performed;

• connectivity solutions offered; and

• pricing of the laboratory’s services.

The Company believes that ongoing consolidation in the clinical laboratory testing business will continue. In addition, the Company believes that it and the other large independent clinical laboratory testing companies will be able to increase their share of the overall clinical laboratory testing market due to a number of factors, including cost efficiencies afforded by large-scale automated testing, reimbursement reductions and managed health care entities that require cost efficient testing services and large service networks. In addition, legal restrictions on physician referrals and their ownership of laboratories, as well as increased regulation of laboratories, are expected to contribute to the continuing consolidation of the industry.

Although testing for health care purposes and customers represents the most significant portion of clinical laboratory business, clinical laboratories also perform testing for other purposes and customers. The Company performs testing in connection with clinical trials for biopharmaceutical and diagnostic development and commercialization; employment and occupational testing; DNA testing to determine parentage and to assist in forensic investigations; veterinary testing; environmental testing; wellness testing; toxicology testing; and pain management testing. Through the acquisition of Covance, the Company will expand its testing services to include testing for nutritional chemistry and food safety.

Like the clinical laboratory industry, the contract research organization industry has many participants. These participants range from hundreds of small, limited-service providers to a limited number of full-service contract research organizations with global capabilities. Covance Drug Development primarily competes against in-house departments of pharmaceutical companies, full-service and limited-service contract research organizations and, to a lesser extent, selected universities and teaching hospitals.

There is competition for customers in the contract research organization industry on the basis of many factors, including the following: reputation for on-time quality performance; expertise and experience in specific areas; scope of service offerings; strengths in various geographic markets; therapeutic areas; price; technological expertise and efficient drug development processes; ability to acquire, process, analyze and report data in a rapid and accurate manner; historic experience and relationships; ability



to manage large-scale clinical trials both domestically and internationally; quality of facilities; expertise and experience in reimbursement and healthcare consulting; and size. The Company believes that Covance Drug Development competes favorably in these areas and that the combined company will continue to compete favorably, including with respect to the strategic opportunities discussed below under Integration Strategy.

## Effect of Market Changes on the Clinical Laboratory Business

In connection with significant changes to health care, the clinical laboratory business is also undergoing significant change. Medicare (which principally serves patients 65 and older), Medicaid (which principally services low-income patients) and insurers have increased their efforts to control the cost, utilization and delivery of health care services. Measures to regulate health care delivery in general and clinical laboratories in particular have resulted in reduced prices, added costs and decreased utilization for the clinical laboratory industry by increasing complexity and adding new regulatory and administrative requirements. From time to time, Congress has also considered changes to the Medicare fee schedules, and the Company believes that pressure to reduce government reimbursement will continue. In March 2010, comprehensive health care reform legislation, the Patient Protection and Affordable Care Act (“ACA”), was enacted. Among its provisions were reductions in the Medicare clinical laboratory fee schedule updates, one of which is a permanent reduction and the other of which applies from 2011 through 2015. On February 17, 2012, Congress passed legislation that reduced payment rates under the Medicare Clinical Laboratory Fee Schedule ("CLFS") by 2%, effective January 1, 2013. This reduction was applied after the adjustment of the fee schedule by the annual CPI update as reduced by the productivity adjustment (0.9%) and the 1.75% reduction under the ACA, and before the scheduled 2% sequestration reduction mandated by the Budget Control Act of 2011, which became effective April 1, 2013. The 2% sequestration reduction applied to both the CLFS, which represented approximately 11.7% of the Company's revenue in 2013, and the Physician Fee Schedule ("PFS"), which represented approximately 1.1% of the Company's revenue in 2013. During 2013, the Company also experienced significant payment reductions to certain surgical pathology procedures and a variety of other government reimbursement reductions. During 2014, the Company experienced a $6.0 million reduction in revenue as a result of a 0.75% adjustment to the CLFS. Reimbursement to physicians under the PFS (which includes certain payments to diagnostic laboratories) was also reduced, resulting in a $6.6 million payment reduction to the Company. During 2015, the Company faces a 0.25% payment reduction to the CLFS and an estimated $2.1 million payment increase to the PFS, assuming the conversion factor remains constant throughout 2015. The PFS assigns relative value units to each procedure or service and a conversion factor is applied to calculate the reimbursement. The conversion factor will decrease by 21.2% on April 1, 2015 due to the Sustainable Growth Rate formula, which would result in a 21.2% payment reduction to the PFS unless Congress acts to prevent the cut, as it has acted to prevent similar cuts for the past decade.

On April 1, 2014, President Obama signed into law the Protecting Access to Medicare Act ("PAMA"), which included provisions to reform the CLFS. Under PAMA, CMS will have no authority to make CLFS adjustments based on technological changes, as CMS had proposed through rulemaking in 2013, and the annual CPI adjustments and the productivity adjustments to the CLFS enacted under the ACA will no longer apply beginning in 2017. However, beginning in 2016, applicable laboratories will be required to report private market data to CMS that CMS will use to calculate weighted median prices that will represent the new CLFS rates beginning in 2017, subject to certain phase-in limits. For 2017-2019, a test price (based on applicable CPT codes) cannot be reduced by more than 10% per year; for 2020-2022, a test price (based on applicable CPT codes) cannot be reduced by more than 15.0% per year. Reporting and pricing will occur every three years, or annually with respect to certain types of tests, to update the CLFS thereafter.

In addition, there are continuing market-based changes in the clinical laboratory business as diagnostic testing continues to shift away from traditional, fee-for-service medicine to managed care. The growth of the managed care sector and consolidation of managed care companies present various challenges and opportunities to the Company and other clinical laboratories. In 2006, the Company signed a ten-year agreement with UnitedHealthcare \( ^{®} \)  to become its exclusive national laboratory. This agreement represented an industry first in terms of its length and exclusivity at a national level. In September 2011, the Company extended this agreement for an additional two years through the end of 2018. The various managed care organizations (“MCOs”) have different contracting philosophies, which are influenced by the design of their products. Some MCOs contract with a limited number of clinical laboratories and engage in direct negotiation of rates. Other MCOs adopt broader networks with generally uniform fee structures for participating clinical laboratories. In addition, some MCOs use capitation to fix the cost of laboratory testing services for their enrollees. Under a capitated reimbursement mechanism, the clinical laboratory and the MCO agree to a per member, per month payment for all authorized laboratory tests ordered during the month, regardless of the number or cost of the tests performed. For the year ended December 31, 2014, capitated contracts with MCOs accounted for approximately 211.1 million, or 3.5% of the Company’s net sales. The Company’s ability to attract and retain managed care clients will become even more important as the impact of various health care reform initiatives continues, including expanded Health Insurance Exchanges and Accountable Care Organizations ("ACOs" or "ACO").

Despite the potential market changes discussed above, the Company believes that the volume of clinical laboratory testing will be positively influenced by several factors, including an expansion of Medicaid, managed care, and private insurance



exchanges, increased knowledge of the human genome leading to an enhanced appreciation of the value of gene-based diagnostic assays and the development of new therapeutics that have a “companion diagnostic” to help identify the subset of the population for whom it is effective or that may suffer adverse events.

The Company believes its enhanced esoteric menu, geographic footprint and operating efficiency provide a strong platform for growth. Additional factors that may lead to future volume growth include an increase in the number and types of tests that are readily available (due to advances in technology and increased cost efficiencies) for testing and diagnosis of disease and the general aging of the population in the U.S. The impact of these factors is expected to be partially offset by declines in volume as a result of increased controls over the utilization of laboratory services by Medicare, Medicaid, and other third-party payers, particularly MCOs. In addition, movement by patients into consumer driven health plans may have an impact on the utilization of laboratory testing.

## Company Mission and Strategy

The Company's mission is to be a trusted knowledge partner for stakeholders, leading to growth in its businesses and continued creation of shareholder value. The Company will achieve this plan through the disciplined execution of its five-pillar strategy.

• Deploy capital to investments that enhance its business and return capital to shareholders,

• Enhance IT capabilities to improve the physician and patient experience,

• Continue to improve efficiency to remain the most efficient and highest value provider of laboratory services,

• Continue scientific innovation to offer new tests at reasonable and appropriate pricing, and

• Develop knowledge services.

The Company believes that the successful execution of this five-pillar strategy will fulfill its core mission of becoming a trusted knowledge partner for stakeholders, by offering the highest quality laboratory testing and most compelling value to its customers.

Pillar One: Deploy capital to investments that enhance the Company's business and return capital to shareholders

As discussed above, the Company completed its acquisition of Covance on February 19, 2015. In the fourth quarter of 2014, the Company completed its acquisitions of LipoScience, Inc., a premier esoteric laboratory focused on personalized diagnostics for cardiovascular and metabolic disorders, and Bode Technology Group, Inc., a provider of specialized forensic DNA analysis, proprietary DNA collection products, and relationship testing.

Since 2009, the Company has invested approximately $7.9 billion in strategic business acquisitions. These acquisitions have strengthened the Company's geographic presence and expanded its specialty testing operations. The Company believes the acquisition market remains attractive with a number of opportunities to strengthen its scientific capabilities, grow esoteric testing and increase presence in key geographic areas.

The Company believes it has some of the premier genetics, oncology and infectious disease businesses in the laboratory industry. With its acquisition of Genzyme Genetics \( ^{1} \)  in December of 2010, combined with its existing genomic capabilities, the Company offers prenatal genetic testing and access to novel testing technologies such as the SMA molecular genetics assay, and the entire Reveal \( ^{®} \)  family of SNP Microarrays, the Inheritest \( ^{®} \)  carrier testing assays and a complete suite of BRCA mutation tests. As market demand for prenatal genetics increases, the Company believes it is well positioned to provide the broadest range of offerings, including the services of approximately 140 genetic counselors. In oncology, the Company's broad molecular oncology test menu and specialized sales force complement the strong pathology expertise of Genzyme Genetics and two of the Company's earlier acquisitions - Accupath Diagnostic Laboratories, Inc. dba US Labs \( ^{2} \)  and Dianon Systems, Inc. \( ^{3} \)  In the area of Infectious Disease, with the acquisition of Monogram Biosciences, Inc. in 2009, the Company expanded its offerings around HIV and HCV detection and monitoring for enhanced management of these diseases.

In 2014, the Company continued to deploy cash and return value to shareholders through share repurchases. During the year, the Company acquired approximately 2.7 million LabCorp shares for $269.0 million. Since 2003, the Company has repurchased approximately $5.9 billion in shares at an average price of approximately $69 per share. Following the announcement of the Covance acquisition, the Company suspended its share repurchases. The Company does not anticipate resuming its share repurchase activity in until it reaches its targeted ratio of total debt to consolidated EBITDA of 2.5 to 1.0.

The Company is reengineering its systems and processes to leverage technological advancements, create a sustainable and more efficient business model, and improve the experience of all stakeholders. The Company expects this initiative to drive net savings in excess of $100.0 million over the next three years.

Pillar Four: Continue scientific innovation to offer new tests at reasonable and appropriate pricing

Innovative tests continue to be an important growth driver for the Company. In 2014, the Company introduced 174 new assays, collaborating with leading companies and academic institutions to provide physicians and patients with the most scientifically advanced testing in the industry.

The Company is playing an important role in many aspects of the emerging model of personalized health care in which treatments and therapeutics are tailored to an individual, often based on his or her genetic signature (or that of a particular tumor/strain of virus). LabCorp is a leader in HIV genotyping, one of the first major advances in personalized medicine, which is used to test for resistance to specific drugs. The Company continues to build on this legacy through publications and the development of new tests and/or resources such as the Food and Drug Administration ("FDA")-approved Prosigna \( ^{™} \)  Breast Cancer Prognostic Gene Signature Assay, which can assess the probability of breast cancer recurrence in certain patients.

The Company continues to invest in and deploy its next-generation sequencing (“NGS”) capabilities. Throughout 2014, LabCorp experienced strong growth with its BRCA test menu for the assessment of breast cancer risk aided by its launch of the BRCA NGS assay, which includes a comprehensive panel of BRCA 1 and 2 complete gene sequence analysis and deletion/duplication testing, targeted analysis tests for other family members once a mutation is identified, and a panel for mutations prevalent among people of Ashkenazi Jewish descent. The Company also introduced HIV GenoSure Archive \( ^{SM} \) , the first genotypic drug resistance assay specifically designed to support individualized drug selection for HIV-1 patients with low or undetectable viral loads. HIV GenoSure Archive \( ^{SM} \)  was developed using a NGS platform.

The Company's test menu expansion in 2014 includes the extensive portfolio of Thermo Scientific ImmunoCAP \( ^{™} \)  allergy testing products from Thermo Fisher Scientific, Inc., and informaSeq \( ^{SM} \)  Prenatal Test, a non-invasive prenatal screening test that can assess risk for abnormalities in the number of chromosomes from a single maternal blood draw.



The Company's leadership role as a global provider of innovative laboratory services in working with pharmaceutical, biotechnology and in vitro diagnostics companies, is significantly enhanced following the acquisition of Covance. Prior to the acquisition, the Company developed, in-licensed and commercialized numerous genetic tests such as ALK, BRAF, EGFR, KRAS and others linked to targeted therapy options. The Company will maintain its strong focus on the development of companion diagnostics. The Company's capabilities in assay development, its access to a broad spectrum of testing platforms, and its experience with clinical trials, further complemented by Covance's robust end-to-end drug development services, enhance LabCorp's market leadership position in genomic testing.

Beyond clinical trials, there are also many examples where companion diagnostics have moved into the commercial setting and are helping improve care, such as: (1) assisting in determining the efficacy of a drug for an individual; (2) helping the physician select the correct dosage; and (3) reducing adverse events. In 2006, 13 companion diagnostics were available. By the end of 2014, that number had grown to 113, with many more in the development pipeline. Companion diagnostics are increasingly understood to be critical to the advancement of health care, as they assist in determining the efficacy of a drug for an individual, help the physician select the correct drug dosage, and reduce adverse patient events. In February 2015, the National Institutes of Health announced a new Precision Medicine Initiative, designed to further the development and use of patient-specific health care, such as companion diagnostics. The Company will continue to play an important role in both bringing new companion diagnostics to the market and making them commercially available once the drug has been approved, leveraging its experience from supporting the clinical trials that demonstrate the safety and efficacy of such products.

## Pillar Five: Develop knowledge services

- Enlighten Health \( ^{SM} \) : Genetic Counseling, a workforce of approximately 140 board-certified genetic counselors that supports both patients and physicians by identifying genetic risks, explaining appropriate genetic testing options, discussing the implications of test results and helping patients make better health care decisions.

The Company's BeaconLBS \( ^{®} \)  Platform is a point-of-care decision support service that interfaces with test ordering systems to assist physicians in lab and test selection, helping them to order the right test for the patient at the right time. Physicians, patients health care delivery systems and payers will benefit from this innovation, which will improve quality and more effectively manage costs without disrupting physician work flow. The Company's rules engine interfaces with payer policies for ordering, utilization, adjudication and payment.

In 2013, BeaconLBS \( ^{®} \)  signed an agreement with UnitedHealthCare to implement its products in Florida. UnitedHealthcare launched the laboratory benefit management program with BeaconLBS \( ^{®} \)  in Florida on October 1, 2014 and its implementation is ongoing.



## Covance Integration Strategy

In addition to remaining committed to its core mission of being a trusted knowledge partner for stakeholders, leading to growth in its businesses and continued creation of shareholder value, the Company intends to continue working towards integrating Covance Drug Development into its operations in order to capitalize on the enhanced capabilities of the combined company. The Company has identified three strategic opportunities as its top priorities during the initial phases of this integration: (i) deliver faster clinical trial enrollment; (ii) become the partner of choice to develop and commercialize companion diagnostics; and (iii) enhance Phase IV clinical trial experience and post-market surveillance.

Deliver faster clinical trial enrollment. Utilizing the Company’s database of more than 70 million unique patient records along with Covance Drug Development’s investigator database and analytic capabilities is expected to enable faster, higher-quality clinical trials, reduce trial cycle time, help to eliminate non-viable sites (the presence of which can delay recruitment), reduce costs and increase revenue for biopharmaceutical company clients.

Partner of choice to develop and commercialize companion diagnostics. As noted above, companion diagnostics will become increasingly important, and currently there are dozens of drugs in Phase III development that will require companion diagnostics. By combining Covance Drug Development’s strength in central laboratory and early-stage clinical development with the Company’s strength in test commercialization, the combined drug development business will be able to offer comprehensive, end-to-end support for companion diagnostic development.

Enhance Phase IV clinical trial experience and post-market surveillance. About 30 percent of Phase IV clinical trial patients drop out due to inconvenient trial procedures and the limited number of trial sites. The Company believes that its 1,750 PSCs, approximately 5,000 phlebotomists in physician offices and convenient patient web portal for scheduling can improve the Phase IV clinical trial patient experience. The Company also believes that its infrastructure will serve another important function, allowing the combined organization to collect post-approval safety data on new drugs. Since 1972, more than 25 approved drugs have been withdrawn from the market, the vast majority due to toxicity. The Company believes that Covance Drug Development’s analytics capabilities can identify early safety signals, avoid extensive recalls, and find genotypical characteristics of patients who experience adverse drug reactions so that the drug can be given to patients for whom it is safe. The combined drug development business is also expected to be able to use these capabilities to assist biopharmaceutical companies in identifying new indications for their drugs through post-market studies.

## Laboratory Testing Operations and Services

The Company has a national network of primary testing laboratories, specialty testing laboratories, branches, PSCs and STAT laboratories. A branch is a central facility that collects specimens in a region for shipment to one of the Company's laboratories for testing. A branch is also frequently used as a base for sales and distribution staff. Generally, a PSC is a facility maintained by the Company to serve the patients of physicians in a medical professional building or other strategic location. The PSC staff collects the specimens for testing if requested by the physician. Most patient specimens are collected by the customer's staff. The specimens, and any accompanying documents including test request forms if the test order was not placed electronically, are collected from customer locations, including in-office phlebotomists, or PSCs and sent, principally through the Company's in-house courier system (and, to a lesser extent, through independent couriers), to one of the Company's primary testing laboratories for testing. Test requests are completed by the client or transcribed by a Company patient service technician from a client order to indicate the tests to be performed and provide the necessary billing information. Some of the Company's PSCs also function as STAT labs, which are laboratories that have the ability to perform certain core tests and report results to the physician quickly.

Each specimen and related request form is checked for completeness and then given a unique identification number. The unique identification number assigned to each specimen helps to ensure that the results are attributed to the correct patient. The test request forms are sent to a data entry operator who ensures that the necessary testing and billing information is entered. Once this information is entered into the software system, the tests are performed and the results are entered through an electronic data interchange interface or manually, depending upon the tests and the type of instrumentation involved. Most of the Company's automated testing equipment is connected to the Company's information systems. Most core testing is completed by early the next morning and test results are in most cases electronically delivered to clients via LabCorp Beacon, smart printers, personal computer-based products or electronic interfaces.

Covance Drug Development offers InTeleCenter \( ^{®} \)  services that employ state of the art phone, internet and electronic media to manage customer communications. InTeleCenter \( ^{®} \)  programs include reimbursement hotlines, patient assistance programs and patient compliance REMS programs.

## Clients

The Company provides testing services to a broad range of health care providers and other customers. During the year ended December 31, 2014, no client or group of clients under the same contract accounted for more than 9.5% of the Company’s consolidated net sales. The primary client groups serviced by the Company include:

Independent Physicians and Physician Groups. Physicians requiring testing for their patients are one of the Company’s primary sources of requests for testing services. Fees for clinical laboratory testing services rendered for these physicians are billed either to the physician, to the patient or the patient’s third-party payer such as an insurance company, Medicare or Medicaid. Billings are typically on a fee-for-service basis. If the billings are to the physician, they are based on a customer fee schedule and are subject to negotiation. Otherwise, the patient or third-party payer is billed at the Company’s patient fee schedule, subject to third-party payer contract terms and negotiation by physicians on behalf of their patients. Patient sales are recorded at the Company’s patient fee schedule, net of any discounts negotiated with physicians on behalf of their patients, or fees made available through charity care or an uninsured patient program. Revenues received from Medicare and Medicaid billings are based on government-set fee schedules and reimbursement rules.

Hospitals. The Company provides hospitals with services ranging from core and specialty testing to laboratory management services. Hospitals generally maintain an on-site laboratory to perform immediately needed testing of patients receiving care. However, they also refer less time sensitive procedures, less frequently needed procedures and highly specialized procedures to outside facilities, including independent clinical laboratories and larger medical centers. The Company typically charges hospitals for any such tests on a fee-for-service basis which is derived from the Company’s client fee schedule. Fees for management services are typically billed monthly at contractual rates.

Managed Care Organizations. The Company serves many MCOs, and these organizations have different contracting philosophies, that are influenced by the design of the products. Some MCOs contract with a limited number of clinical laboratories and engage in direct negotiation of rates. Other MCOs adopt broader networks with generally uniform fee structures for participating clinical laboratories. In addition, some MCOs use capitation to fix the cost of laboratory testing services for their enrollees. Under a capitated reimbursement mechanism, the clinical laboratory and the MCO agree to a per member, per month payment to pay for all authorized laboratory tests ordered.

Other Institutions. The Company serves other institutions, including government agencies, large employers, pharmaceutical companies and other independent clinical laboratories that do not have the breadth of the Company’s testing capabilities. These institutions typically pay on a negotiated fee-for-service basis.

With its acquisition of Covance, the Company’s client base has expanded both in size and character. Covance Drug Development provides its services, on a global basis, primarily to the pharmaceutical and biotechnology industries. Covance Drug Development serves in excess of 1,000 biopharmaceutical companies, ranging from the world’s largest pharmaceutical companies and biotechnology companies to small and start-up organizations.

## Payers

Testing services are billed to Medicare, Medicaid, commercial clients, MCOs and other insurance companies, independent physicians and physician groups, hospitals and private patients. Tests ordered by a physician may be billed to different payers depending on the medical benefits of a particular patient. Most testing services are billed to a party other than the physician or other authorized person who ordered the test. For the year ended December 31, 2014, requisitions (based on the total volume of



requisitions excluding the Company's non-U.S. clinical diagnostic laboratory operations in Ontario, Canada, which is reviewed separately by corporate management for the purposes of allocation of resources) and average revenue per requisition by payer are as follows:

<table><tr><td></td><td>Requisition Volume as a % of Total</td><td>Revenue per Requisition</td></tr><tr><td>Private Patients</td><td>1.3</td><td>193.08</td></tr><tr><td>Medicare and Medicaid</td><td>14.4</td><td>49.21</td></tr><tr><td>Commercial Clients</td><td>34.6</td><td>40.76</td></tr><tr><td>Managed Care</td><td>49.7</td><td>41.94</td></tr></table>

A portion of the managed care fee-for-service revenues are collectible from patients in the form of deductibles, copayments, coinsurance and non-covered tests.

For the Company’s subsidiary operations in Ontario, Canada, the Ministry of Health determines who can establish a licensed community medical laboratory and caps the amount that each of these licensed laboratories can bill the government sponsored health care plan. The Ontario government-sponsored health care plan covers the cost of clinical laboratory testing performed by the licensed laboratories. The provincial government discounts the annual testing volumes based on certain utilization discounts and establishes an annual maximum it will pay for all community laboratory tests. The agreed-upon reimbursement rates are subject to Ministry of Health review at the end of each year and can be adjusted (at the government’s discretion) based upon the actual volume and mix of test work performed by the licensed providers in the province during the year. In 2014, the amount of the Company’s cap revenue derived from the Ontario government sponsored health care plan was CN$202.1 million.

## Seasonality

The Company experiences seasonality in its testing business. The volume of testing generally declines during the year-end holiday periods and other major holidays. Volume can also decline due to inclement weather, reducing net revenues and cash flows. Given the seasonality of the testing business, comparison of results for successive quarters may not accurately reflect trends or results for the full year.

## Investments in Joint Venture Partnerships

The Company holds investments in three joint venture partnerships; located in Milwaukee, Wisconsin, Alberta, Canada and Florence, South Carolina. These businesses primarily represent partnership agreements between the Company and other independent diagnostic laboratory investors. Under these agreements, all partners share in the profits and losses of the businesses in proportion to their respective ownership percentages. All partners are actively involved in the major business decisions made by each joint venture.

The Canadian partnership has a license to conduct diagnostic testing services in the province of Alberta. Substantially all of its revenue is received as reimbursement from the Alberta government's health care programs. While the Canadian license guarantees the joint venture the ability to conduct diagnostic testing in Alberta, it does not guarantee that the provincial government will continue to reimburse diagnostic laboratory testing in future years at current levels. If the provincial government decides to limit or reduce its reimbursement of laboratory diagnostic services, it would have a negative impact on the profits and cash flows the Company derives from its Canadian joint venture. In December 2013, Alberta Health Services (“AHS”), the Alberta government's health care program, issued a request for proposals for laboratory services that includes the scope of services performed by the Canadian partnership. In October 2014, AHS informed the Canadian partnership that it was not selected as the preferred proponent. In November 2014, the Canadian partnership submitted a vendor bid appeal and it is vigorously protesting the contract award. AHS has established a Vendor Bid Appeal Panel to hear the appeal, and the hearing occurred on February 23-25, 2015, and a decision is pending. If the AHS contract award remains with the preferred proponent, then the Canadian partnership's revenues would decrease substantially and the carrying value of the Company's investment could potentially be impaired.

## Sales, Marketing and Client Service

The Company offers its diagnostic services through a sales force focused on serving the specific needs of customers in different market segments. These market segments generally include Primary Care, Obstetrics-Gynecology, Specialty Medicine (e.g., Infectious Disease, Endocrinology, Gastroenterology and Rheumatology), Oncology and Hospitals.



The Company’s sales force is compensated through a combination of salaries, commissions and bonuses at levels commensurate with each individual’s qualifications, performance and responsibilities. The general sales force is responsible for both new sales and customer retention. This general sales force is also supported by a team of clinical specialists who focus on selling esoteric testing and meeting the unique needs of the specialty medicine markets.

The Company competes primarily on the basis of quality of testing, breadth of menu, price, innovation of services, convenience and access points throughout the nation.

## Information Systems

The Company has developed and implemented information management systems (“IS”) supporting its operations, as well as positioning the Company as a trusted knowledge partner. The Company operates standard platforms for its core business services including laboratory, billing, financial and reporting systems. These standard systems ensure consistency and availability on a national scale. Additionally, the Company continues to expand its primary laboratory capabilities with services supporting digital pathology and enhanced specialty lab solutions. With approximately 90.7% of its domestic revenue (approximately 85.9% of consolidated revenue) processed through these systems, the Company’s centralized IS platforms provide tremendous operational efficiencies, enabling the Company to provide consistent, structured, and standardized laboratory results and superior patient care at a national level.

In response to continued market demand for electronic laboratory data and a commitment to improving the physician and patient experience, the Company continues to expand its LabCorp Beacon \( ^{®} \)  platform with new capabilities and services. The Company continues to leverage information technology advancements to deliver enhanced services through its LabCorp Beacon: Patient product and expanded access to AccuDraw \( ^{®} \)  and LabCorp Touch \( ^{®} \)  capabilities. Additionally, the Company will continue to expand and improve client connectivity through its LabCorp Beacon platform designed to improve lab-related workflow such as ordering tests and sharing, viewing and analyzing lab results. The platform is also available in a mobile edition accessible via market leading mobile devices. LabCorp Beacon is a key component of the Company's connectivity portfolio, whereby the Company provides physicians a choice of tailored solutions that also include robust integration with electronic medical records/electronic health records and personal health records ("PHR") applications.

The focus on the advancement of health information technology is a reflection of the growing demand for self-service, integrated health care data and decision support capabilities. The Company's centralized analytic platform delivers enhanced analytic services and decision support to physicians, hospitals, local communities, state agencies and national networks. The Company has a number of new population health analytics programs in development to provide health care business intelligence tools to hospitals, physician practices, and ACOs. These tools assist customers in their compliance and reporting requirements with respect to efficient management of their productivity, quality and patient outcome metrics. The Company's robust rules engine maintains a large number of clinical quality measures that are highly customizable and provide full compliance with Meaningful Use requirements and ACO, Joint Commission and PQRS reporting requirements. Real time clinical alerts highlight gaps in care for patients and patient populations. These industry-leading, data driven services position LabCorp as a trusted partner to health care stakeholders, providing the knowledge to optimize decision making, improve health outcomes and reduce treatment costs.

## Billing

Billing for laboratory services is a complicated process involving many payers such as MCOs, Medicare, Medicaid, physicians and physician groups, hospitals, patients and employer groups, all of which have different billing requirements. In addition, billing process arrangements with third-party administrators may further complicate the billing process.

The Company utilizes a centralized billing system in the collection of approximately 90.7% of its domestic revenue (85.9% of consolidated revenue). This system generates bills to customers based on payer type. Client billing is typically generated monthly, whereas patient and third-party billing are typically generated daily. Agings of accounts receivable are then monitored by billing personnel and re-bills and follow-up activities are conducted as necessary. Bad debt expense is recorded within selling, general and administrative expenses as a percentage of sales considered necessary to maintain the allowance for doubtful accounts at an appropriate level, based on the Company's experience with its accounts receivable. The Company writes off accounts against the allowance for doubtful accounts when accounts receivable are deemed to be uncollectible. For client billing, third party and managed care, accounts are written off when all reasonable collection efforts prove to be unsuccessful. Patient accounts are written off after the normal dunning cycle has occurred and the account has been transferred to a third-party collection agency.



A significant portion of the Company’s bad debt expense is related to accounts receivable from patients who are unwilling or unable to pay. In 2014, the Company continued its focus on process initiatives to reduce the negative impact of patient accounts receivable by collecting payment at the point of service and refining its internal patient collection cycle. The Company is also focused on an enterprise-wide effort as part of Project LaunchPad to identify clients with high concentrations of write offs and implement strategies to improve the financial performance of those accounts.

Another component of the Company’s bad debt expense is the result of non-credit related issues that slow the billing process, such as missing or incorrect billing information on requisitions. The Company vigorously attempts to obtain any missing information or rectify any incorrect billing information received from the health care provider. However, the Company typically performs the requested tests and returns the test results regardless of whether billing information is incorrect or incomplete. The Company believes that this experience is similar to that of its primary competitors. The Company continues to focus on process initiatives aimed at reducing the impact of these non-credit related issues by reducing the number of requisitions received that are missing billing information or have incorrect information. This is accomplished through on-going identification of root-cause issues, training provided to internal and external resources involved in the patient data capture process, and an emphasis on the use of electronic requisitions.

## Quality

The Company has established a comprehensive quality management program for its laboratories and other facilities designed to assure that quality systems and processes are in place to facilitate accurate and timely test results. This includes licensing, credentialing, training and competency of professional and technical staff, and process audits. In addition to the external inspections and proficiency testing programs required by CMS and other regulatory agencies, systems and procedures are in place to emphasize and monitor quality. All of the Company’s laboratories are subject to on-site regulatory evaluations, external proficiency testing programs (e.g., the College of American Pathologists, or “CAP”), state surveys and the Company’s own quality audit programs.

Quality also encompasses all facets of the Company’s service, including turnaround time, client service, patient satisfaction, and billing. The Company’s quality assessment program includes measures that compare its current performance against desired performance goals detailed in its quality improvement plan. Using quality assessment techniques, the Company’s laboratories employ a variety of programs to monitor critical aspects of service to its clients and patients.

In addition, the Company’s supply chain management department provides oversight to monitor and control vendor products and performance, and plays an essential role in the Company’s approach to quality through improvements in automation.

Customer Interaction. Processes to continually improve the customers’ experience with the Company are essential. Use of technology and improvements in workflow within the Company’s PSCs are helping to reduce patient wait times by expediting the patient registration process (through LabCorp Patient Appointment Scheduling) and ensuring that appropriate specimens are obtained based upon requested test requirements (through LabCorp Touch \( ^{SM} \)  and AccuDraw \( ^{®} \) ).

Specimen Management. The use of logistics and specimen tracking technology allows the timely transportation, monitoring, and storage of specimens. The Company is continually improving its ability to timely collect, transport and track specimens from clients and between LabCorp locations.

Quality Control. The Company regularly performs quality control testing by running quality control samples with known values at the same time patient samples are tested. Quality control test results are entered into the Company's computerized quality control database. In addition, the patient mean is continually monitored to detect potential analytical variances during testing. The real-time monitoring for any statistically and clinically significant analytical differences enables technologists and technicians to take immediate and appropriate corrective action prior to release of patient results.

Internal Proficiency Testing. The Company has an extensive internal proficiency testing program in which each laboratory receives samples to test. This internal proficiency program serves to test the Company’s analytical and post-analytical phases of laboratory testing service including order entry, requisitioning systems, accuracy, precision of its testing protocols, and technologist/technician performance. This program supplements the external proficiency programs required by the laboratory accrediting agencies.

Accreditation. The Company participates in numerous externally-administered quality surveillance programs, including the CAP program. CAP is an independent non-governmental organization of board-certified pathologists which offers an accreditation program to which laboratories voluntarily subscribe. CAP has been granted deemed status authority by CMS to inspect clinical laboratories to determine adherence to the Clinical Laboratory Improvement Amendments of 1988 (“CLIA”) standards. The CAP program involves both on-site inspections of the laboratory and participation in CAP’s proficiency testing program for all categories.



in which the laboratory is accredited. All of the Company's major laboratories are accredited by CAP. A laboratory's receipt of accreditation by CAP satisfies the CMS requirement for certification.

The Company's forensic crime laboratories located in Dallas, TX and Lorton, VA are accredited to ISO/IEC 17025:2005 by the American Society of Crime Laboratory Directors, Laboratory Accreditation Board (“ASCLD/LAB”) in the discipline of Biology and categories of nuclear DNA, mitochondrial DNA, body fluid identification and individual characteristic database testing. Under the accreditation program managed by the ASCLD/LAB, a crime laboratory undergoes a comprehensive and in-depth inspection to demonstrate that its management, operations, employees, procedures and instruments, physical plant, and security and personnel safety procedures meet stringent quality standards.

The Company's full service forensic facilities in the United Kingdom are accredited to ISO/IEC 17025:2005 by the United Kingdom Accreditation Service in many areas of forensic analysis. These facilities provide crime scene investigative services, collecting samples for DNA analysis, mitochondrial DNA, microscopic analysis, tool marks, paint, and other forms of forensic testing.

The Company has eight labs that have received ISO 15189:2007 accreditation. The ISO 15189:2007 standard recognizes the technical competence of medical laboratories, thus providing a ready means for customers to find reliable high quality testing. The list below reflects the Company's labs that have achieved this accreditation and the year in which they achieved it.

## Intellectual Property Rights

The Company relies on a combination of patents, trademarks, copyrights, trade secrets and nondisclosure and non-competition agreements to establish and protect its proprietary technology. The Company has filed and obtained numerous patents in the U.S. and abroad, and regularly files patent applications, when appropriate, to establish and protect its proprietary technology. From time to time, the Company also licenses U.S. and non-U.S. patents, patent applications, technology, trade secrets, know-how, copyrights or trademarks owned by others. The Company believes, however, that no single patent, technology, trademark, intellectual property asset or license is material to its business as a whole.

## Employees

As of December 31, 2014 the Company had over 36,000 full-time equivalent employees worldwide. Subsidiaries of the Company have three collective bargaining agreements, which cover approximately 625 employees. The Company’s success is highly dependent on its ability to attract and retain qualified employees, and the Company believes that it has good working relationships with its employees. As of December 31, 2014, Covance had over 12,000 equivalent full-time employees, approximately 47% of whom were employed outside of the United States and 12,185 of whom were full time employees. Covance Drug Development is not a party to any collective bargaining agreements.

## Regulation and Reimbursement

## General

The clinical laboratory industry is subject to significant governmental regulation at the federal, state and local levels. As described below, these regulations concern licensure and operation of clinical laboratories, claim submission and reimbursement for laboratory services, health care fraud and abuse, security and confidentiality of health information, quality, and environmental and occupational safety.



## Regulation of Clinical Laboratories

CLIA extends federal oversight to virtually all clinical laboratories by requiring that they be certified by the federal government or by a federally-approved accreditation agency. CLIA requires that all clinical laboratories meet quality assurance, quality control and personnel standards. Laboratories also must undergo proficiency testing and are subject to inspections.

Standards for testing under CLIA are based on the complexity of the tests performed by the laboratory, with tests classified as "high complexity," "moderate complexity," or "waived." Laboratories performing high complexity testing are required to meet more stringent requirements than moderate complexity laboratories. Laboratories performing only waived tests, which are tests determined by the Food and Drug Administration to have a low potential for error and requiring little oversight, may apply for a certificate of waiver exempting them from most of the requirements of CLIA. All major and many smaller Company facilities hold CLIA certificates to perform high complexity testing. The Company's remaining smaller testing sites hold CLIA certificates to perform moderate complexity testing or a certificate of waiver. The sanctions for failure to comply with CLIA requirements include suspension, revocation or limitation of a laboratory's CLIA certificate, which is necessary to conduct business, cancellation or suspension of the laboratory's approval to receive Medicare and/or Medicaid reimbursement, as well as significant fines and/or criminal penalties. The loss or suspension of a CLIA certification, imposition of a fine or other penalties, or future changes in the CLIA law or regulations (or interpretation of the law or regulations) could have a material adverse effect on the Company.

The Company is also subject to state and local laboratory regulation. CLIA provides that a state may adopt laboratory regulations different from or more stringent than those under federal law, and a number of states have implemented their own laboratory regulatory requirements. State laws may require that laboratory personnel meet certain qualifications, specify certain quality controls, or require maintenance of certain records.

The Company believes that it is in compliance with all applicable laboratory requirements. The Company's laboratories have continuing programs to ensure that their operations meet all such regulatory requirements, but no assurances can be given that the Company's laboratories will pass all future licensure or certification inspections.

## FDA Laws and Regulations

The FDA has regulatory responsibility over instruments, test kits, reagents and other devices used by clinical laboratories. On July 26, 2007, the FDA issued Draft Guidance for Industry, Clinical Laboratories, and FDA Staff: In Vitro Diagnostic Multivariate Index Assays (“the Draft Guidance”). The Draft Guidance announced that devices deemed In Vitro Diagnostic Multivariate Index Assays (“IVDMIs”) are Class II or Class III devices requiring, among other things, pre-market notification clearance or pre-market approval from FDA. This guidance would change the agency’s historical practice regarding regulation of certain laboratory-developed tests. On September 20, 2014, the FDA released two additional draft guidance documents: “Framework for Regulatory Oversight of Laboratory Developed Tests (LDTs)” which provides an overview of how FDA would regulate LDTs through a risk-based approach and “FDA Notification and Medical Device Reporting for Laboratory Developed Tests” which provides guidance on how the FDA would collect information on existing LDTs and begin adverse event reporting. There are other regulatory and legislative proposals that would increase general FDA oversight of clinical laboratories and laboratory-developed tests. The outcome and ultimate impact of such proposals on the business is difficult to predict at this time.

The FDA enforces laws and regulations that govern the development, testing, manufacturing, labeling, advertising, marketing, distribution and surveillance of diagnostic products. The Company’s MedTox Diagnostic Inc.’s point of collection testing devices and LipoScience’s in vitro diagnostic assays and instrumentation are subject to regulation by the FDA. The FDA periodically inspects and reviews the manufacturing processes and product performance of diagnostic products. The FDA has the authority to take various administrative and legal actions for non-compliance such as fines, product suspensions, warning letters, recalls, injunctions and other civil and criminal sanctions.

## Payment for Clinical Laboratory Services

In 2014, the Company derived approximately 16.0% of its net sales directly from the Medicare and Medicaid programs. In addition, the Company's other clinical laboratory testing business that is not directly related to Medicare or Medicaid nevertheless depends significantly on continued participation in these programs and in other government health care programs, in part because clients often want a single laboratory to perform all of their testing services. In recent years, both governmental and private sector payers have made efforts to contain or reduce health care costs, including reducing reimbursement for clinical laboratory services.

Reimbursement under the Medicare program for clinical diagnostic laboratory services is subject to a clinical laboratory fee schedule that sets the maximum amount payable in each Medicare carrier's jurisdiction. This clinical laboratory fee schedule is



updated annually. Laboratories bill the program directly for covered tests performed on behalf of Medicare beneficiaries. State Medicaid programs are prohibited from paying more than the Medicare fee schedule limit for clinical laboratory services furnished to Medicaid recipients. Approximately 11.7% of the Company’s revenue is reimbursed under the Medicare clinical laboratory fee schedule.

Payment under the Medicare fee schedule has been limited from year to year by Congressional action, including imposition of national limitation amounts and freezes on the otherwise applicable annual Consumer Price Index ("CPI") updates. For most diagnostic lab tests, the national limitation is now 74.0% of the national median of all local fee schedules established for each test. Under a provision of the Medicare, Medicaid, and SCHIP Benefits Improvement and Protection Act of 2000 ("BIPA"), for tests performed after January 1, 2001 that the Secretary of Health and Human Services determines are new tests for which no limitation amount has previously been established, the cap is set at 100% of the median.

Following a five year freeze on CPI updates to the CLFS, there was a 1.2% increase in the fee schedule in 2003. In late 2003, the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (“MMA”) again imposed a freeze in the CPI update of the CLFS from 2004 through 2008. The MMA freeze expired December 31, 2008. Pursuant to the Medicare Improvements for Patients and Providers Act of 2008 ("MIPPA"), the CPI update for labs for the years 2009 through 2013 would have been reduced by 0.5%. After such reduction, the 2009 CPI update to the CLFS was an increase of 4.5% and the 2010 CPI update was a reduction of 1.9%. In March 2010, comprehensive health care reform legislation, the Patient Protection and Affordable Care Act (“ACA”), was enacted, which replaced the MIPPA provisions with new provisions that may fundamentally change the health care delivery system in the U.S. Among the ACA’s provisions were reductions in the Medicare clinical laboratory fee schedule updates, one of which is a permanent reduction and the other of which applies from 2011 through 2015. On February 17, 2012, Congress passed legislation that reduced payment rates under the Medicare Clinical Laboratory Fee Schedule ("CLFS") by 2%, effective January 1, 2013. This reduction was applied after the adjustment of the fee schedule by the annual CPI update as reduced by the productivity adjustment (0.9%) and the 1.75% reduction under the ACA, and before the scheduled 2% sequestration reduction mandated by the Budget Control Act of 2011, which became effective April 1, 2013. The 2% sequestration reduction applied to both the CLFS, which represents approximately 11.7% of the Company's revenue, and the PFS, which represents approximately 1.1% of the Company's revenue in 2013. During 2013, the Company also faced significant payment reductions to certain surgical pathology procedures and a variety of other government reimbursement reductions.

During 2014, the Company experienced a $6.0 million reduction in revenue as a result of a 0.75% adjustment to the CLFS. Reimbursement to physicians under the PFS (which includes certain payments to diagnostic laboratories) was also reduced, resulting in a $6.6 million payment reduction to the Company. On November 27, 2013, CMS finalized a proposal to begin annual evaluations of reimbursement rates for CLFS codes based on technological changes, volume, growth in utilization, cost and time on the CLFS. Under this proposal, test codes for which CMS was contemplating a payment adjustment would be listed in the Proposed PFS Rule each year, and the first adjustments to payment rates were scheduled to begin January 1, 2015. However, in April, 2014, the PAMA was signed into law, which removed CMS's authority to adjust the CLFS based on technological changes and established a new method for setting CLFS rates, beginning to be implemented in 2016. PAMA also repealed, beginning in 2017, the annual CPI and productivity adjustments to the CLFS enacted under the ACA. Beginning in 2016, under the provisions of PAMA, applicable laboratories will be required to report private market data to CMS that CMS will use to calculate test-specific weighted median prices that will represent the new CLFS rates beginning in 2017, subject to certain phase-in limits. For 2017-2019, a test price (based on applicable CPT codes) cannot be reduced by more than 10.0% per year; for 2020-2022, a test price (based on applicable CPT codes) cannot be reduced by more than 15.0% per year. Reporting and pricing will occur every three years, or annually for certain types of tests, to update the CLFS thereafter. Since rulemaking to implement the provisions of PAMA has not yet begun, it is too early to assess the impact of PAMA.

Separate from clinical laboratory services, which generally are reimbursed under the CLFS, many pathology services are reimbursed under the PFS. The PFS assigns relative value units to each procedure or service, and a conversion factor is applied to calculate the reimbursement. The PFS is also subject to adjustment on an annual basis. The formula used to calculate the fee schedule conversion factor would have resulted in significant decreases in payment for most physician services for each year since 2003. However, since that time Congress has intervened repeatedly to prevent these payment reductions, and the conversion factor has been increased or frozen for the subsequent year. Decreases continue in future years unless Congress acts to change the formula used to calculate the fee schedule or continues to mandate freezes or increases each year. On February 17, 2012, Congress passed legislation to avert significant payment reductions in March, and extended existing Medicare physician rates through December 31, 2012 and Congress took action again at the end of 2012, passing the American Taxpayer Relief Act of 2012, which maintained current rates through 2013. It is not clear when or how Congress will address this issue in the long term. If Congress does not continue to block payment reductions under the statutory formula, significant reductions in the PFS rates could have an adverse effect on the Company. Approximately 1.1% of the Company’s revenue is reimbursed under the PFS.



Because a significant portion of the Company's costs are relatively fixed, Medicare, Medicaid and other government program payment reductions could have a direct adverse effect on the Company's net earnings and cash flows. The Company cannot predict whether changes will be implemented that will result in further payment reductions.

In addition to changes in reimbursement rates, the Company is also impacted by changes in coverage policies for laboratory tests. Congressional action in 1997 required HHS to adopt uniform coverage, administration and payment policies for many of the most commonly performed lab tests using a negotiated rulemaking process. The negotiated rulemaking committee established uniform policies limiting Medicare coverage for certain tests to patients with specified medical conditions or diagnoses, replacing local Medicare coverage policies which varied around the country. Since the final rules generally became effective in 2002, the use of uniform policies has improved the Company's ability to obtain necessary billing information in some cases. However, Medicare, Medicaid and private payer diagnosis code requirements and payment policies continue to negatively impact the Company's ability to be paid for some of the tests it performs. The Company also experienced delays in the pricing and implementation of new molecular pathology codes among various payers, including Medicaid, Medicare and commercial carriers. While some delays were expected, several non-commercial payers required an extended period of time to price key molecular codes and a number of those payers, mostly government entities, indicated that they would no longer pay for tests that they had previously covered. Further, several payers are requiring additional information to process claims or have implemented prior authorization policies. Many commercial payers were delayed in becoming aware of the impact of their claim edits and policies which impeded access to services which previously have been covered and reimbursed. These delays had a negative impact on 2014 revenue, revenue per requisition, margins and cash flows and are expected to have a continuing negative impact. Similarly, coding changes related to toxicology and other procedures are being implemented in 2015 and Palmetto has published a revised Drugs of Abuse Local Coverage Policy which, if implemented as written, would adversely impact Medicare revenue. The policy has been delayed several times. It is currently published to be effective April 1, 2015 and it not clear what policies Medicaid and Managed Care organizations may implement in response. The Company expects delays in the pricing and implementation of these new toxicology codes and it is unclear what impact will be experienced related to price and margins.

Future changes in federal, state and local laws and regulations (or in the interpretation of current regulations) affecting government payment for clinical laboratory testing could have a material adverse effect on the Company. Based on currently available information, the Company is unable to predict what type of changes in legislation or regulations, if any, will occur.

## Standard Electronic Transactions, Security and Confidentiality of Health Information

The Health Insurance Portability and Accountability Act of 1996 ("HIPAA") was designed to address issues related to the security and confidentiality of health insurance information. In an effort to improve the efficiency and effectiveness of the health care system by facilitating the electronic exchange of information in certain financial and administrative transactions, HIPAA regulations were promulgated. These regulations apply to health plans, health care providers that conduct standard transactions electronically and health care clearinghouses (“covered entities”). Five such regulations have been finalized: (i) the Transactions and Code Sets Rule; (ii) the Privacy Rule; (iii) the Security Rule; (iv) the Standard Unique Employer Identifier Rule, which requires the use of a unique employer identifier in connection with certain electronic transactions; and (v) the National Provider Identifier Rule, which requires the use of a unique health care provider identifier in connection with certain electronic transactions.

The Privacy Rule regulates the use and disclosure of protected health information (“PHI”) by covered entities. It also sets forth certain rights that an individual has with respect to his or her PHI maintained by a covered entity, such as the right to access or amend certain records containing PHI or to request restrictions on the use or disclosure of PHI. The Privacy Rule requires covered entities to contractually bind third parties, known as business associates, in the event that they perform an activity or service for or on behalf of the covered entity that involves access to PHI. The Security Rule establishes requirements for safeguarding patient information that is electronically transmitted or electronically stored. The Company believes that it is in compliance in all material respects with the requirements of the HIPAA Privacy and Security Rules.

The federal Health Information Technology for Economic and Clinical Health (“HITECH”) Act, which was enacted in February 2009, strengthens and expands the HIPAA Privacy and Security Rules and their restrictions on use and disclosure of PHI. HITECH includes, but is not limited to, prohibitions on exchanging patient identifiable health information for remuneration and additional restrictions on the use of PHI for marketing. HITECH also fundamentally changes a business associate’s obligations by imposing a number of Privacy Rule requirements and a majority of Security Rule provisions directly on business associates that were previously only directly applicable to covered entities. Moreover, HITECH requires covered entities to provide notice to individuals, HHS, and, as applicable, the media when unsecured protected health information is breached, as that term is defined by HITECH. Business associates are similarly required to notify covered entities of a breach. The omnibus HIPAA regulation implementing most of the HITECH provisions was issued in January 2013 and made significant changes to the HIPAA Privacy, Security, Enforcement, and Breach Notification Rules. Compliance with most of the changes became required on September 23, 2013. The Company’s policies and procedures are fully compliant with the HITECH Act requirements.



On February 6, 2014, CMS published final regulations that amend the HIPAA Privacy Rule to provide individuals (or their personal representatives) with the right to receive copies of their test reports from laboratories subject to HIPAA, or to request that copies of their test reports be transmitted to designated third parties with a compliance date of October 4, 2014. Previously laboratories that were CLIA-certified or CLIA-exempt were not subject to the provision in the Privacy Rule that provides individuals with the right of access to PHI. The HIPAA Privacy Rule amendment resulted in the preemption of a number of state laws that prohibit a laboratory from releasing a test report directly to the individual. The Company revised its policies and procedures to comply with these new access requirements and has updated its privacy notice to reflect individuals' new access rights under this final rule.

The total cost associated with the requirements of HIPAA and HITECH is not expected to be material to the Company’s operations or cash flows. However, future regulations and interpretations of HIPAA and HITECH could impose significant costs on the Company.

In addition to the federal HIPAA regulations described above, there are a number of state laws regarding the confidentiality of medical information, some of which apply to clinical laboratories. These laws vary widely but they most commonly restrict the use and disclosure of medical and financial information. In some cases, state laws are more restrictive and, therefore, are not preempted by HIPAA. Penalties for violation of these laws may include sanctions against a laboratory's licensure, as well as civil and/or criminal penalties. Violations of the HIPAA provisions could result in civil and/or criminal penalties, including significant fines and up to 10 years in prison. HITECH also significantly strengthened HIPAA enforcement by increasing the civil penalty amounts that may be imposed, requiring HHS to conduct periodic audits to confirm compliance and authorizing state attorneys general to bring civil actions seeking either injunctions or damages in response to violations of the HIPAA privacy and security regulations that affect the privacy of state residents. Additionally, numerous other countries have or are developing similar laws governing the collection, use, disclosure and transmission of personal or patient information.

The administrative simplification provisions of HIPAA mandate the adoption of standard unique identifiers for health care providers. The intent of these provisions is to improve the efficiency and effectiveness of the electronic transmission of health information. The National Provider Identification rule requires that all HIPAA-covered health care providers, whether they are individuals or organizations, must obtain a National Provider Identifier (“NPI”) to identify themselves in standard HIPAA transactions. NPI replaces the unique provider identification number - as well as other provider numbers previously assigned by payers and other entities - for the purpose of identifying providers in standard electronic transactions. The Company believes that it is in compliance with the HIPAA National Provider Identification Rule in all material respects.

The standard unique employer identifier regulations require that employers have standard national numbers that identify them on standard transactions. The Employer Identification Number (also known as a Federal Tax Identification Number) issued by the Internal Revenue Service was selected as the identifier for employers and was adopted effective July 30, 2002. The Company believes it is in compliance with these requirements.

The Company believes that it is in compliance in all material respects with the current Transactions and Code Sets Rule. The Company implemented Version 5010 of the HIPAA Transaction Standards and is within the testing and implementation phase of the rule to adopt the ICD-10-CM code set. The compliance date for ICD-10-CM is October 1, 2015. The costs associated with ICD-10-CM Code Set were substantial, and failure of the Company, third party payers or physicians to transition within the required timeframe could have an adverse impact on reimbursement, days sales outstanding and cash collections. As a result of inconsistent application of transaction standards by payers or the Company’s inability to obtain certain billing information not usually provided to the Company by physicians, the Company could face increased costs and complexity, a temporary disruption in receipts and ongoing reductions in reimbursements and net revenues.

The Company believes it is in compliance in all material respects with the Operating Rules for electronic funds transfers and remittance advice transactions, for which the compliance date was January 1, 2014.

## Fraud and Abuse Laws and Regulations

Existing federal laws governing federal health care programs, including Medicare and Medicaid, as well as similar state laws, impose a variety of broadly described fraud and abuse prohibitions on health care providers, including clinical laboratories. These laws are interpreted liberally and enforced aggressively by multiple government agencies, including the U.S. Department of Justice, HHS' Office of Inspector General ("OIG"), and various state agencies. Historically, the clinical laboratory industry has been the focus of major governmental enforcement initiatives. The federal government's enforcement efforts have been increasing over the past decade, in part as a result of the enactment of HIPAA, which included several provisions related to fraud and abuse enforcement, including the establishment of a program to coordinate and fund federal, state and local law enforcement efforts. The Deficit



Reduction Act of 2005 also included new requirements directed at Medicaid fraud, including increased spending on enforcement and financial incentives for states to adopt false claims act provisions similar to the federal False Claims Act. Recent amendments to the False Claims Act, as well as other enhancements to the federal fraud and abuse laws enacted as part of the ACA, are widely expected to further increase fraud and abuse enforcement efforts. For example, the ACA established an obligation to report and refund overpayments from Medicare within 60 days of identification; failure to comply with this new requirement can give rise to additional liability under the False Claims Act and Civil Monetary Penalties statute. On February 16, 2012, CMS issued a proposed rule to establish regulations addressing the reporting and returning of overpayments. The rule has not been finalized.

The federal health care programs' anti-kickback law (the "Anti-Kickback Law") prohibits knowingly providing anything of value in return for, or to induce, the referral of Medicare, Medicaid or other federal health care program business. Violations can result in imprisonment, fines, penalties, and/or exclusion from participation in federal health care programs. The OIG has published "safe harbor" regulations which specify certain arrangements that are protected from prosecution under the Anti-Kickback law if all conditions of the relevant safe harbor are met. Failure to fit within a safe harbor does not necessarily constitute a violation of the Anti-Kickback Law; rather, the arrangement would be subject to scrutiny by regulators and prosecutors and would be evaluated on a case by case basis. Many states have their own Medicaid anti-kickback laws and several states also have anti-kickback laws that apply to all payers (i.e., not just government health care programs).

From time to time, the OIG issues alerts and other guidance on certain practices in the health care industry that implicate the Anti-Kickback Law or other federal fraud and abuse laws. Examples of such guidance documents particularly relevant to the Company and its operations follow.

In October 1994, the OIG issued a Special Fraud Alert on arrangements for the provision of clinical laboratory services. The Fraud Alert set forth a number of practices allegedly engaged in by some clinical laboratories and health care providers that raise issues under the federal fraud and abuse laws, including the Anti-Kickback Law. These practices include: (i) providing employees to furnish valuable services for physicians (other than collecting patient specimens for testing) that are typically the responsibility of the physicians' staff; (ii) offering certain laboratory services at prices below fair market value in return for referrals of other tests which are billed to Medicare at higher rates; (iii) providing free testing to physicians' managed care patients in situations where the referring physicians benefit from such reduced laboratory utilization; (iv) providing free pick-up and disposal of bio-hazardous waste for physicians for items unrelated to a laboratory's testing services; (v) providing general-use facsimile machines or computers to physicians that are not exclusively used in connection with the laboratory services; and (vi) providing free testing for health care providers, their families and their employees (i.e., so-called "professional courtesy" testing). The OIG emphasized in the Special Fraud Alert that when one purpose of such arrangements is to induce referrals of program-reimbursed laboratory testing, both the clinical laboratory and the health care provider (e.g., physician) may be liable under the Anti-Kickback Law, and may be subject to criminal prosecution and exclusion from participation in the Medicare and Medicaid programs. More recently, in June 2014, the OIG issued another Special Fraud Alert addressing compensation paid by laboratories to referring physicians for blood specimen processing and for submitting patient data to registries. This Special Fraud Alert reiterates the OIG's longstanding concerns about payments from laboratories to physicians in excess of the fair market value of the physician's services and payments that reflect the volume or value of referrals of federal health care program business.

Another issue the OIG has expressed concern about involves the provision of discounts on laboratory services billed to customers in return for the referral of federal health care program business. In a 1999 Advisory Opinion, the OIG concluded that a proposed arrangement whereby a laboratory would offer physicians significant discounts on non-federal health care program laboratory tests might violate the Anti-Kickback Law. The OIG reasoned that the laboratory could be viewed as providing such discounts to the physician in exchange for referrals by the physician of business to be billed by the laboratory to Medicare at non-discounted rates. The OIG indicated that the arrangement would not qualify for protection under the discount safe harbor to the Anti-Kickback Law because Medicare and Medicaid would not get the benefit of the discount. Similarly, in a 1999 correspondence, the OIG stated that if any direct or indirect link exists between a discount that a laboratory offers to a skilled nursing facility for tests covered under Medicare’s payments to the skilled nursing facility and the referral of tests billable by the laboratory under Medicare Part B, then the Anti-Kickback Law would be implicated.

The OIG also has issued guidance regarding joint venture arrangements that may be viewed as suspect under the Anti-Kickback Law. These documents have relevance to clinical laboratories that are part of (or are considering establishing) joint ventures with potential sources of federal health care program business. The first guidance document, which focused on investor referrals to such ventures was issued in 1989 and another concerning contractual joint ventures was issued in April 2003. Some of the elements of joint ventures that the OIG identified as “suspect” include: arrangements in which the capital invested by the physicians is disproportionately small and the return on investment is disproportionately large when compared to a typical investment; specific selection of investors who are in a position to make referrals to the venture; and arrangements in which one of the parties to the joint venture expands into a line of business that is dependent on referrals from the other party (sometimes called "shell" joint ventures). In a 2004 advisory opinion, the OIG expressed concern about a proposed joint venture in which a laboratory company



would assist physician groups in establishing off-site pathology laboratories. The OIG indicated that the physicians' financial and business risk in the venture was minimal and that the physicians would contract out substantially all laboratory operations, committing very little in the way of financial, capital, or human resources. The OIG was unable to exclude the possibility that the arrangement was designed to permit the laboratory to pay the physician groups for their referrals, and, therefore, was unwilling to find that the arrangement fell within a safe harbor or had sufficient safeguards to protect against fraud or abuse.

Violations of other fraud and abuse laws also can result in exclusion from participation in federal health care programs, including Medicare and Medicaid. One basis for such exclusion is an individual or entity’s submission of claims to Medicare or Medicaid that are substantially in excess of that individual or entity’s usual charges for like items or services. In 2003, the OIG issued a notice of proposed rulemaking that would have defined the terms “usual charges” and “substantially in excess” in ways that might have required providers, including the Company, to either lower their charges to Medicare and Medicaid or increase charges to certain other payers to avoid the risk of exclusion. On June 18, 2007, however, the OIG withdrew the proposed rule, saying it preferred to continue evaluating billing patterns on a case-by-case basis. In its withdrawal notice, the OIG also said it “remains concerned about disparities in the amounts charged to Medicare and Medicaid when compared to private payers,” that it continues to believe its exclusion authority for excess charges “provides useful backstop protection for the public fisc from providers that routinely charge Medicare or Medicaid substantially more than their other customers” and that it will continue to use “all tools available … to address instances where Medicare or Medicaid are charged substantially more than other payers.” Thus, although the OIG did not proceed with its rulemaking, an enforcement action under this statutory exclusion basis is possible and, if pursued, could have an adverse effect on the Company. The enforcement by Medicaid officials of similar state law restrictions also could have a material adverse effect on the Company.

Under another federal statute, known as the "Stark Law" or "self-referral" prohibition, physicians who have a financial or a compensation relationship with a clinical laboratory may not, unless an exception applies, refer Medicare patients for testing to the laboratory, regardless of the intent of the parties. Similarly, laboratories may not bill Medicare for services furnished pursuant to a prohibited self-referral. There are several Stark law exceptions that are relevant to arrangements involving clinical laboratories, including: 1) fair market value compensation for the provision of items or services; 2) payments by physicians to a laboratory for clinical laboratory services; 3) an exception for certain ancillary services (including laboratory services) provided within the referring physician's own office, if certain criteria are satisfied; 4) physician investment in a company whose stock is traded on a public exchange and has stockholder equity exceeding $75.0; and 5) certain space and equipment rental arrangements that are set at a fair market value rate and satisfy other requirements. All of the requirements of a Stark Law exception must be met in order for the exception to apply. Many states have their own self-referral laws as well, which in some cases apply to all patient referrals, not just Medicare.

There are a variety of other types of federal and state fraud and abuse laws, including laws prohibiting submission of false or fraudulent claims. The Company seeks to conduct its business in compliance with all federal and state fraud and abuse laws. The Company is unable to predict how these laws will be applied in the future, and no assurances can be given that its arrangements will not be subject to scrutiny under such laws. Sanctions for violations of these laws may include exclusion from participation in Medicare, Medicaid and other federal or state health care programs, significant criminal and civil fines and penalties, and loss of licensure. Any exclusion from participation in a federal health care program, or any loss of licensure, arising from any action by any federal or state regulatory or enforcement authority, would likely have a material adverse effect on the Company's business. In addition, any significant criminal or civil penalty resulting from such proceedings could have a material adverse effect on the Company's business.

## Environmental, Health and Safety

The Company is subject to licensing and regulation under federal, state and local laws and regulations relating to the protection of the environment and human health and safety and laws and regulations relating to the handling, transportation and disposal of medical specimens, infectious and hazardous waste and radioactive materials. All Company laboratories are subject to applicable federal and state laws and regulations relating to biohazard disposal of all laboratory specimens and the Company generally utilizes outside vendors for disposal of such specimens. In addition, the federal Occupational Safety and Health Administration (“OSHA”) has established extensive requirements relating to workplace safety for health care employers, including clinical laboratories, whose workers may be exposed to blood-borne pathogens such as HIV, the hepatitis B virus and the hepatitis C virus. These regulations, among other things, require work practice controls, protective clothing and equipment, training, medical follow-up, vaccinations and other measures designed to minimize exposure to, and transmission of, blood-borne pathogens.

In 2012, the federal OSHA Hazard Communication Standard was revised based on the adoption of the Globally Harmonized System (GHS) that provides criteria for the classification of chemical hazards. Updated copies of Safety Data Sheets for chemical products used across the Company are being obtained prior to the effective date of June 1, 2015.



The Company seeks to comply with such federal, state and local laws and regulations. Failure to comply could subject the Company to various administrative and/or other enforcement actions.

## Drug Testing

Drug testing for public sector employees is regulated by the Substance Abuse and Mental Health Services Administration (“SAMHSA”), which has established detailed performance and quality standards that laboratories must meet to be approved to perform drug testing on employees of federal government contractors and certain other entities. To the extent that the Company’s laboratories perform such testing, each must be certified as meeting SAMHSA standards. The Company’s laboratories in Research Triangle Park, North Carolina, Raritan, New Jersey, Houston, Texas, Southaven, Mississippi, and St. Paul, Minnesota are all SAMHSA certified.

## Controlled Substances

The use of controlled substances in testing for drugs of abuse is regulated by the Federal Drug Enforcement Administration.

## Compliance Program

The Company maintains a comprehensive, company-wide compliance program. The Company continuously evaluates and monitors its compliance with all Medicare, Medicaid and other rules and regulations. The objective of the Company’s compliance program is to develop, implement, and update compliance safeguards as necessary. Emphasis is placed on developing compliance policies and guidelines, personnel training programs and various monitoring and audit procedures to attempt to achieve implementation of all applicable rules and regulations.

The Company seeks to conduct its business in compliance with all statutes, regulations, and other requirements applicable to its clinical laboratory operations. The clinical laboratory testing industry is, however, subject to extensive regulation, and many of these statutes and regulations have not been interpreted by the courts. There can be no assurance that applicable statutes and regulations will not be interpreted or applied by a prosecutorial, regulatory or judicial authority in a manner that would adversely affect the Company. Potential sanctions for violation of these statutes and regulations include significant fines and the loss of various licenses, certificates, and authorizations, which could have a material adverse effect on the Company’s business.

## Item 1A. Risk Factors

## Risks Associated with the Company’s Business

Changes in federal, state, local and third-party payer regulations or policies (or in the interpretation of current regulations or policies), insurance regulation or approvals or changes in other laws, regulations or policies may adversely affect governmental and third-party coverage and reimbursement for clinical laboratory testing and may have a material adverse effect upon the Company’s business.

Government payers, such as Medicare and Medicaid, as well as insurers, including MCOs, have increased their efforts to control the cost, utilization and delivery of health care services. From time to time, Congress has considered and implemented changes in the Medicare fee schedules in conjunction with budgetary legislation. Further reductions of reimbursement for Medicare and Medicaid services or changes in policy regarding coverage of tests or other requirements for payment, such as prior authorization or a physician or qualified practitioner’s signature on test requisitions, may be implemented from time to time. Reimbursement for the pathology services component of the Company’s business is also subject to statutory and regulatory reduction. Reductions in the reimbursement rates and changes in payment policies of other third-party payers may occur as well. Such changes in the past have resulted in reduced payments as well as added costs and have decreased test utilization for the clinical laboratory industry by adding more complex new regulatory and administrative requirements. Further changes in federal, state, local and third-party payer regulations or policies may have a material adverse impact on the Company’s business. Actions by agencies regulating insurance or changes in other laws, regulations, or policies may also have a material adverse effect upon the Company’s business.

The Company could face significant monetary damages and penalties and/or exclusion from the Medicare and Medicaid programs if it violates health care anti-fraud and abuse laws.

The Company is subject to extensive government regulation at the federal, state and local levels. The Company’s failure to meet governmental requirements under these regulations, including those relating to billing practices and financial relationships with physicians and hospitals, could lead to civil and criminal penalties, exclusion from participation in Medicare and Medicaid and possible prohibitions or restrictions on the use of its laboratories. While the Company believes that it is in material compliance



with all statutory and regulatory requirements, there is a risk that government authorities might take a contrary position. Such occurrences, regardless of their outcome, could damage the Company’s reputation and adversely affect important business relationships it has with third parties.

The Company’s business could be harmed from the loss or suspension of a license or imposition of a fine or penalties under, or future changes in, or interpretations of, the law or regulations of the Clinical Laboratory Improvement Act of 1967, and the Clinical Laboratory Improvement Amendments of 1988, the FDA or those of Medicare, Medicaid or other federal, state or local agencies.

The clinical laboratory testing industry is subject to extensive regulation, and many of these statutes and regulations have not been interpreted by the courts. CLIA extends federal oversight to virtually all clinical laboratories by requiring that they be certified by the federal government or by a federally-approved accreditation agency. The sanction for failure to comply with CLIA requirements may be suspension, revocation or limitation of a laboratory’s CLIA certificate, which is necessary to conduct business, as well as significant fines and/or criminal penalties. In addition, the Company is subject to regulation under state law. State laws may require that laboratories and/or laboratory personnel meet certain qualifications, specify certain quality controls or require maintenance of certain records. The FDA regulates diagnostic products and periodically inspects and reviews their manufacturing processes and product performance. The Company’s MedTox Diagnostic Inc.’s point of collection testing devices are subject to regulation by the FDA.

Applicable statutes and regulations could be interpreted or applied by a prosecutorial, regulatory or judicial authority in a manner that would adversely affect the Company's business. Potential sanctions for violation of these statutes and regulations include significant fines and the suspension or loss of various licenses, certificates and authorizations, or product suspensions or recalls which could have a material adverse effect on the Company's business. In addition, compliance with future legislation could impose additional requirements on the Company which may be costly, including FDA regulation of laboratory developed tests.

Failure to comply with environmental, health and safety laws and regulations, including the federal Occupational Safety and Health Administration Act and the Needlestick Safety and Prevention Act, could result in fines and penalties and loss of licensure, and have a material adverse effect upon the Company’s business.

The Company is subject to licensing and regulation under federal, state and local laws and regulations relating to the protection of the environment and human health and safety, including laws and regulations relating to the handling, transportation and disposal of medical specimens, infectious and hazardous waste and radioactive materials, as well as regulations relating to the safety and health of laboratory employees. All of the Company’s laboratories are subject to applicable federal and state laws and regulations relating to biohazard disposal of all laboratory specimens, and they utilize outside vendors for disposal of such specimens. In addition, the federal Occupational Safety and Health Administration has established extensive requirements relating to workplace safety for health care employers, including clinical laboratories, whose workers may be exposed to blood-borne pathogens such as HIV and the hepatitis B virus. These requirements, among other things, require work practice controls, protective clothing and equipment, training, medical follow-up, vaccinations and other measures designed to minimize exposure to, and transmission of, blood-borne pathogens. In addition, the Needlestick Safety and Prevention Act requires, among other things, that the Company include in its safety programs the evaluation and use of engineering controls such as safety needles if found to be effective at reducing the risk of needlestick injuries in the workplace.

Failure to comply with federal, state and local laws and regulations could subject the Company to denial of the right to conduct business, fines, criminal penalties and/or other enforcement actions which would have a material adverse effect on its business. In addition, compliance with future legislation could impose additional requirements on the Company which may be costly.

Regulations requiring the use of “standard transactions” for health care services issued under HIPAA may negatively impact the Company’s profitability and cash flows.

Pursuant to HIPAA, the Secretary of HHS has issued regulations designed to improve the efficiency and effectiveness of the health care system by facilitating the electronic exchange of information in certain financial and administrative transactions while protecting the privacy and security of the information exchanged.

The HIPAA transaction standards are complex, and subject to differences in interpretation by payers. For instance, some payers may interpret the standards to require the Company to provide certain types of information, including demographic information not usually provided to the Company by physicians. In addition, new requirements for additional standard transactions, such as claims attachments, and the ICD-10-CM Code Set, could prove technically difficult, time-consuming or expensive to implement.



The costs associated with ICD-10-CM Code Set were substantial, and failure of the Company, third party payers or physicians to transition within the required timeframe could have an adverse impact on reimbursement, days sales outstanding and cash collections. As a result of inconsistent application of other transaction standards by payers or the Company’s inability to obtain certain billing information not usually provided to the Company by physicians, the Company could face increased costs and complexity, a temporary disruption in receipts and ongoing reductions in reimbursements and net revenues. The Company is working closely with its payers to establish acceptable protocols for claim submission and with its trade association and an industry coalition to present issues and problems as they arise to the appropriate regulators and standards setting organizations.

Failure to maintain the security of customer-related information or compliance with security requirements could damage the Company’s reputation with customers, cause it to incur substantial additional costs and to become subject to litigation.

The Company receives certain personal and financial information about its customers. In addition, the Company depends upon the secure transmission of confidential information over public networks, including information permitting cashless payments. A compromise in the Company’s security systems that results in customer personal information being obtained by unauthorized persons or the Company’s failure to comply with security requirements for financial transactions could adversely affect the Company’s reputation with its customers and others, as well as the Company’s results of operations, financial condition and liquidity. It could also result in litigation against the Company or the imposition of penalties.

Failure of the Company, third party payers or physicians to comply with the ICD-10-CM Code Set by the compliance date of October 1, 2015, could negatively impact the Company's reimbursement, profitability and cash flow.

The Company believes that it is in compliance in all material respects with the current Transactions and Code Sets Rule. The Company implemented Version 5010 of the HIPAA Transaction Standards, and is within the testing and implementation phase of the rule to adopt the ICD-10-CM Code Set. The compliance date for ICD-10-CM is October 1, 2015. Clinical laboratories are typically required to submit health care claims with diagnosis codes to third party payers. The diagnosis codes must be obtained from the ordering physician. The failure of the Company, third party payers or physicians to transition within the required timeframe could have an adverse impact on reimbursement, days sales outstanding and cash collections.

Compliance with the HIPAA security regulations and privacy regulations may increase the Company’s costs.

The HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive federal standards with respect to the use and disclosure of protected health information by health plans, health care providers and health care clearinghouses, in addition to setting standards to protect the confidentiality, integrity and security of protected health information. The regulations establish a complex regulatory framework on a variety of subjects, including:

- the circumstances under which the use and disclosure of protected health information are permitted or required without a specific authorization by the patient, including but not limited to treatment purposes, activities to obtain payments for the Company’s services, and its health care operations activities;

• a patient’s rights to access, amend and receive an accounting of certain disclosures of protected health information;

• the content of notices of privacy practices for protected health information;

• administrative, technical and physical safeguards required of entities that use or receive protected health information; and

• the protection of computing systems maintaining ePHI.

The Company has implemented policies and procedures related to compliance with the HIPAA privacy and security regulations, as required by law. The privacy and security regulations establish a “floor” and do not supersede state laws that are more stringent. Therefore, the Company is required to comply with both federal privacy and security regulations and varying state privacy and security laws. In addition, for health care data transfers from other countries relating to citizens of those countries, the Company must comply with the laws of those other countries. The federal privacy regulations restrict the Company’s ability to use or disclose patient identifiable laboratory data, without patient authorization, for purposes other than payment, treatment or health care operations (as defined by HIPAA), except for disclosures for various public policy purposes and other permitted purposes outlined in the privacy regulations. HIPAA, as amended by HITECH, provides for significant fines and other penalties for wrongful use or disclosure of protected health information in violation of the privacy and security regulations, including potential civil and criminal fines and penalties. Due to the enactment of HITECH, it is not possible to predict what the extent of the impact on business will be; however, if the Company does not comply with existing or new laws and regulations related to protecting the privacy and security of health information it could be subject to monetary fines, civil penalties or criminal sanctions. In addition, other federal and state laws that protect the privacy and security of patient information may be subject to enforcement and interpretations by various governmental authorities and courts resulting in complex compliance issues. For example, the Company could incur



damages under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health information or other private personal information.

Increased competition, including price competition, could have a material adverse impact on the Company’s net revenues and profitability.

The clinical laboratory business is intensely competitive both in terms of price and service. Pricing of laboratory testing services is often one of the most significant factors used by health care providers and third-party payers in selecting a laboratory. As a result of the clinical laboratory industry undergoing significant consolidation, larger clinical laboratory providers are able to increase cost efficiencies afforded by large-scale automated testing. This consolidation results in greater price competition. The Company may be unable to increase cost efficiencies sufficiently, if at all, and as a result, its net earnings and cash flows could be negatively impacted by such price competition. The Company may also face increased competition from companies that do not comply with existing laws or regulations or otherwise disregard compliance standards in the industry. Additionally, the Company may also face changes in fee schedules, competitive bidding for laboratory services or other actions or pressures reducing payment schedules as a result of increased or additional competition.

Discontinuation or recalls of existing testing products; failure to develop, or acquire, licenses for new or improved testing technologies; or the Company’s customers using new technologies to perform their own tests could adversely affect the Company’s business.

From time to time, manufacturers discontinue or recall reagents, test kits or instruments used by the Company to perform laboratory testing. Such discontinuations or recalls could adversely affect the Company’s costs, testing volume and revenue.

The clinical laboratory industry is subject to changing technology and new product introductions. The Company’s success in maintaining a leadership position in genomic and other advanced testing technologies will depend, in part, on its ability to develop, acquire or license new and improved technologies on favorable terms and to obtain appropriate coverage and reimbursement for these technologies. The Company may not be able to negotiate acceptable licensing arrangements and it cannot be certain that such arrangements will yield commercially successful diagnostic tests. If the Company is unable to license these testing methods at competitive rates, its research and development costs may increase as a result. In addition, if the Company is unable to license new or improved technologies to expand its esoteric testing operations, its testing methods may become outdated when compared with the Company’s competition and testing volume and revenue may be materially and adversely affected.

In addition, advances in technology may lead to the development of more cost-effective technologies such as point-of-care testing equipment that can be operated by physicians or other health care providers in their offices or by patients themselves without requiring the services of freestanding clinical laboratories. Development of such technology and its use by the Company’s customers could reduce the demand for its laboratory testing services and negatively impact its revenues.

Currently, most clinical laboratory testing is categorized as “high” or “moderate” complexity, and thereby is subject to extensive and costly regulation under CLIA. The cost of compliance with CLIA makes it impractical for most physicians to operate clinical laboratories in their offices, and other laws limit the ability of physicians to have ownership in a laboratory and to refer tests to such a laboratory. Manufacturers of laboratory equipment and test kits could seek to increase their sales by marketing point-of-care laboratory equipment to physicians and by selling test kits approved for home or physician office use to both physicians and patients. Diagnostic tests approved for home use are automatically deemed to be “waived” tests under CLIA and may be performed in physician office laboratories as well as by patients in their homes with minimal regulatory oversight. Other tests meeting certain FDA criteria also may be classified as “waived” for CLIA purposes. The FDA has regulatory responsibility over instruments, test kits, reagents and other devices used by clinical laboratories and has taken responsibility from the Centers for Disease Control for classifying the complexity of tests for CLIA purposes. Increased approval of “waived” test kits could lead to increased testing by physicians in their offices or by patients at home, which could affect the Company’s market for laboratory testing services and negatively impact its revenues.

Health care reform and related products (e.g. Health Insurance Exchanges), changes in government payment and reimbursement systems, or changes in payer mix, including an increase in capitated reimbursement mechanisms and evolving delivery models, could have a material adverse impact on the Company's net revenues, profitability and cash flow.

Testing services are billed to private patients, Medicare, Medicaid, commercial clients, managed care organizations ("MCOs") and other insurance companies. Tests ordered by a physician may be billed to different payers depending on the medical insurance benefits of a particular patient. Most testing services are billed to a party other than the physician or other authorized person that ordered the test. Increases in the percentage of services billed to government and managed care payers could have an adverse



impact on the Company’s net revenues. For the year ended December 31, 2014, requisitions (based on the total volume of requisitions excluding the Company's Other segment) by payer were:

• private patients – 1.3%

• Medicare and Medicaid – 14.4%

• commercial clients – 34.6%

• managed care – 49.7%

The various MCOs have different contracting philosophies, which are influenced by the design of the products they offer to their members. Some MCOs contract with a limited number of clinical laboratories and engage in direct negotiation of the rates reimbursed to participating laboratories. Other MCOs adopt broader networks with a generally largely uniform fee structure for participating clinical laboratories. In addition, some MCOs have used capitation in an effort to fix the cost of laboratory testing services for their enrollees. Under a capitated reimbursement mechanism, the clinical laboratory and the managed care organization agree to a per member, per month payment to pay for all authorized laboratory tests ordered during the month by the physician for the members, regardless of the number or cost of the tests actually performed. Capitation shifts the risk of increased test utilization (and the underlying mix of testing services) to the clinical laboratory provider. The Company makes significant efforts to ensure that its services are adequately compensated in its capitated arrangements. For the year ended December 31, 2014, such capitated contracts accounted for approximately $211.1 million, or 3.7%, of the Company's net sales.

The Company's ability to attract and retain managed care clients is critical given the impact of health care reform, related products and expanded coverage (e.g. Health Insurance Exchanges and Medicaid Expansion) and evolving delivery models (e.g. Accountable Care Organizations).

A portion of the managed care fee-for-service revenues are collectible from patients in the form of deductibles, copayments and coinsurance. As patient cost-sharing increases, collectibility may be impacted.

In addition, Medicare and Medicaid and private insurers have increased their efforts to control the cost, utilization and delivery of health care services, including clinical laboratory services. Measures to regulate health care delivery in general, and clinical laboratories in particular, have resulted in reduced prices, added costs and decreased test utilization for the clinical laboratory industry by increasing complexity and adding new regulatory and administrative requirements. Pursuant to legislation passed in late 2003, the percentage of Medicare beneficiaries enrolled in Medicare managed care plans has increased. The percentage of Medicaid beneficiaries enrolled in Medicaid managed care plans has also increased, and is expected to continue to increase. Implementation of the ACA, the health care reform legislation passed in 2010, also may affect coverage, reimbursement, and utilization of laboratory services, as well as administrative requirements.

The Company also experienced delays in the pricing and implementation of new molecular pathology codes among various payers, including Medicaid, Medicare and commercial carriers. While some delays were expected, several non-commercial payers required an extended period of time to price key molecular codes and a number of those payers, mostly government entities, indicated that they would no longer pay for tests that they had previously covered. Further, several payers are requiring additional information to process claims or have implemented prior authorization policies. Many commercial payers were delayed in becoming aware of the impact of their claim edits and policies which impeded access to services which previously have been covered and reimbursed. These delays had a negative impact on 2014 revenue, revenue per requisition, margins and cash flows and are expected to have a continuing negative impact. Similarly, coding changes related to toxicology and other procedures are being implemented in 2015 and Palmetto has published a revised Drugs of Abuse Local Coverage Policy which, if implemented as written, would adversely impact the Company's Medicare revenue. The policy has been delayed several times. It is currently published to be effective April 1, 2015 and it is not clear what policies Medicaid and Managed Care organizations may implement in response. The Company expects delays in the pricing and implementation of the new toxicology codes and it is unclear what impact will be experienced related to price and margins.

The Company expects efforts to impose reduced reimbursement, more stringent payment policies and utilization and cost controls by government and other payers to continue. If the Company cannot offset additional reductions in the payments it receives for its services by reducing costs, increasing test volume and/or introducing new procedures, it could have a material adverse impact on the Company’s net revenues, profitability and cash flows.

As an employer, health care reform legislation also contains numerous regulations that will require the Company to implement significant process and record keeping changes to be in compliance. These changes increase the cost of providing health care coverage to employees and their families. Given the limited release of regulations to guide compliance, the exact impact to employers including the Company is uncertain.



A failure to obtain and retain new customers, a loss of existing customers or material contracts, a reduction in tests ordered or specimens submitted by existing customers, or the inability to retain existing and create new relationships with health systems could impact the Company’s ability to successfully grow its business.

To offset efforts by payers to reduce the cost and utilization of clinical laboratory services, the Company needs to obtain and retain new customers and business partners. In addition, a reduction in tests ordered or specimens submitted by existing customers, without offsetting growth in its customer base, could impact the Company’s ability to successfully grow its business and could have a material adverse impact on the Company’s net revenues and profitability. The Company competes primarily on the basis of the quality of testing, reporting and information systems, reputation in the medical community, the pricing of services and ability to employ qualified personnel. The Company’s failure to successfully compete on any of these factors could result in the loss of customers and a reduction in the Company’s ability to expand its customer base.

In addition, as the broader health care industry trend of consolidation continues, including the acquisition of physician practices by health systems, relationships with hospital-based health systems and integrated delivery networks are becoming more important. The Company has a well-established base of relationships with those systems and networks, including collaborative agreements. The Company’s inability to retain its existing relationships with those provider systems and networks and to create new relationships could impact its ability to successfully grow its business.

A failure to identify and successfully close and integrate strategic acquisition targets could have a material adverse impact on the Company's business objectives and its net revenues and profitability.

Part of the Company's strategy involves deploying capital in investments that enhance the Company's business, which includes pursuing strategic acquisitions to strengthen the Company's scientific capabilities, grow esoteric testing capabilities and increase presence in key geographic areas. Since 2009, the Company has invested approximately $7.9 billion in strategic business acquisitions for these purposes. However, the Company cannot assure that it will be able to identify acquisition targets that are attractive to the Company or that are of a large enough size to have a meaningful impact on the Company's operating results. Furthermore, the successful closing and integration of a strategic acquisition entails numerous risks, including, among others:

• failure to obtain regulatory clearance, including due to antitrust concerns;

• loss of key customers or employees;

• difficulty in consolidating redundant facilities and infrastructure and in standardizing information and other systems;

• unidentified regulatory problems;

• failure to maintain the quality of services that such companies have historically provided;

• coordination of geographically-separated facilities and workforces; and

• diversion of management's attention from the day-to-day business of the Company.

The Company cannot assure that current or future acquisitions, if any, or any related integration efforts will be successful, or that the Company’s business will not be adversely affected by any future acquisitions, including with respect to net revenues and profitability. Even if the Company is able to successfully integrate the operations of businesses that it may acquire in the future, the Company may not be able to realize the benefits that it expects from such acquisitions.

Adverse results in material litigation matters could have a material adverse effect upon the Company’s business.

The Company may become subject in the ordinary course of business to material legal action related to, among other things, intellectual property disputes, professional liability and employee-related matters, as well as inquiries and requests for information from governmental agencies and bodies and Medicare or Medicaid carriers requesting comment and/or information on allegations of billing irregularities or billing and pricing arrangements that are brought to their attention through billing audits or third parties. Legal actions could result in substantial monetary damages as well as damage to the Company’s reputation with customers, which could have a material adverse effect upon its business.

An inability to attract and retain experienced and qualified personnel could adversely affect the Company’s business.

The loss of key management personnel or the inability to attract and retain experienced and qualified employees at the Company’s clinical laboratories and research centers could adversely affect the business. The success of the Company is dependent in part on the efforts of key members of its management team. Success in maintaining the Company’s leadership position in genomic and other advanced testing technologies will depend in part on the Company’s ability to attract and retain skilled research professionals.



In addition, the success of the Company’s clinical laboratories also depends on employing and retaining qualified and experienced laboratory professionals, including specialists, who perform clinical laboratory testing services. In the future, if competition for the services of these professionals increases, the Company may not be able to continue to attract and retain individuals in its markets. The Company’s revenues and earnings could be adversely affected if a significant number of professionals terminate their relationship with the Company or become unable or unwilling to continue their employment.

Unionization of employees, union strikes, or work stoppages could adversely affect the Company's operations and have a material effect upon the Company's business.

The Company is a party to collective bargaining agreements with various labor unions. Disputes with regard to the terms of these agreements or its potential inability to negotiate acceptable contracts with these unions could result in, among other things, labor unrest, strikes, work stoppages, or other slowdowns by the affected workers. If unionized workers were to engage in a strike, work stoppage, or other slowdown, or other employees were to become unionized, the Company could experience a significant disruption of its operations or higher ongoing labor costs, either of which could have a material adverse effect upon the Company's business. Additionally, future labor agreements, or renegotiation of labor agreements or provisions of labor agreements, could compromise its service reliability and significantly increase its costs, which could have a material adverse impact upon the Company's business.

A significant increase in the Company’s days sales outstanding could increase bad debt expense and have an adverse effect on the Company’s business including its cash flow.

Billing for laboratory services is a complex process. Laboratories bill many different payers including doctors, patients, hundreds of insurance companies, Medicare, Medicaid and employer groups, all of which have different billing requirements. In addition to billing complexities, the Company is experiencing increasing patient responsibility as a result of managed care fee-for-service plans which continue to increase patient copayments, coinsurance and deductibles. A material increase in the Company’s days sales outstanding level (“DSO”) resulting in an increase in the Company’s bad debt expense could have an adverse effect on the Company’s business including its cash flow.

Failure in the Company’s information technology systems or delays or failures in the development and implementation of the Company's LabCorp Beacon \( ^{®} \)  platform could significantly increase testing turn-around time or billing processes and otherwise disrupt the Company’s operations or customer relationships.

The Company’s laboratory operations and customer relationships depend, in part, on the continued performance of its information technology systems. Despite network security measures and other precautions the Company has taken, its information technology systems are potentially vulnerable to physical or electronic break-ins, computer viruses and similar disruptions. In addition, the Company is in the process of integrating the information technology systems of its recently acquired subsidiaries, and the Company may experience system failures or interruptions as a result of this process. Sustained system failures or interruption of the Company’s systems in one or more of its laboratory operations could disrupt the Company’s ability to process laboratory requisitions, perform testing, provide test results in a timely manner and/or bill the appropriate party. The Company is also continuing to enhance its LabCorp Beacon platform and could experience delays or deficiencies in the development process. Failure of the Company’s information technology systems could adversely affect the Company’s business, profitability and financial condition.

Operations may be disrupted and adversely impacted by the effects of natural disasters such as adverse weather and earthquakes, or acts of terrorism, or other criminal activities, or disease pandemics.

Such events may result in a temporary decline in the number of patients who seek laboratory testing services. In addition, such events may temporarily interrupt the Company’s ability to transport specimens, the Company’s information technology systems, the Company’s ability to utilize certain laboratories, and/or the Company’s ability to receive material from its suppliers.

A significant deterioration in the economy could negatively impact testing volumes, cash collections and the availability of credit.

The Company’s operations are dependent upon ongoing demand for diagnostic testing services by patients, physicians, hospitals, MCOs, and others. A significant downturn in the economy could negatively impact the demand for diagnostic testing as well as the ability of patients and other payers to pay for services ordered. In addition, uncertainty in the credit markets could reduce the availability of credit and impact the Company’s ability to meet its financing needs in the future.



Hardware and software failures, delays in the operation of computer and communications systems, the failure to implement system enhancements or cyber security breaches may harm the Company.

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

Changes in reimbursement by foreign governments and foreign currency exchange fluctuations could have an adverse impact on the Company’s business.

The Company has business and operations outside the U.S. Changes by foreign governments in reimbursement for the Company’s services and foreign currency fluctuations could have an adverse impact on the Company’s business.

The Company's growing international operations could subject it to additional risks and expenses that could adversely impact the business or results of operations.

The expansion of the Company's international operations exposes it to risks from failure to comply with foreign laws and regulations that differ from those under which the Company operates in the U.S. In addition, the Company may be adversely affected by other risks of expanded operations in foreign countries, including export controls and trade regulations, changes in tax policies or other foreign laws, restrictions on currency repatriation, judicial systems that less strictly enforce contractual rights, countries that provide less protection for intellectual property rights, and procedures and actions affecting approval, production, pricing, reimbursement and marketing of products and services. Further, international operations could subject the Company to additional expenses that the Company may not fully anticipate, including those related to enhanced time and resources necessary to comply with foreign laws and regulations, difficulty in collecting accounts receivable and longer collection periods, and difficulties and costs of staffing and managing foreign operations. In some countries, the Company's success will depend in part on its ability to form relationships with local partners. The Company's inability to identify appropriate partners or reach mutually satisfactory arrangements could adversely affect the business and operations.

## Risks Associated with Company’s Acquisition of Covance

In order to fund the Covance acquisition, the Company has materially reduced its cash balance and has taken on substantial additional indebtedness.

The Company completed the acquisition of Covance on February 19, 2015 (the "Acquisition"). To fund the consideration to be paid to Covance stockholders pursuant to the terms of the Merger Agreement, the Company used approximately $4.3 billion in cash and issued approximately 15.3 shares of the Company's common stock. On November 2, 2014, in connection with entering into the Merger Agreement with Covance, the Company entered into a bridge facility commitment letter. Under the bridge facility commitment letter, the lenders agreed to provide a $4.25 billion senior unsecured bridge term loan credit facility consisting of $3.85 billion 364-day unsecured bridge tranche and a $400.0 million 60-day unsecured cash bridge tranche for the purpose of financing all or a portion of the cash consideration and the fees and expenses in connection with the transactions contemplated by the Merger Agreement. On December 19, 2014, the Company entered into a five-year term loan credit facility in the principal amount of $1.0 billion for the purpose of financing a portion of the cash consideration and the fees and expenses in connection with the transactions contemplated by the Merger Agreement. Pursuant to the bridge facility commitment letter, upon the Company's entry into the term loan credit facility, the $4.25 billion bridge facility was reduced to a $3.25 billion commitment, comprising a $2.85 billion 364-day unsecured debt bridge tranche and a $400.0 million 60-day cash bridge tranche. The $1.0 billion of term loan commitments made under the term loan credit facility reduced the debt bridge tranche under the bridge facility dollar for



dollar. The term loan credit facility was advanced in full on February 19, 2015, the date of the Company’s completion of the acquisition.

On January 30, 2015, the Company issued $2.9 billion in debt securities, consisting of $500.0 million aggregate principal amount of 2.625% Senior Notes due 2020, $500.0 million aggregate principal amount of 3.20% Senior Notes due 2022, $1.0 billion aggregate principal amount of 3.60% Senior Notes due 2025 and $900.0 million aggregate principal amount of 4.700% Senior Notes due 2045 (together, the “Acquisition Notes”). Net proceeds from the offering of the Acquisition Notes were $2,868.4 million after deducting underwriting discounts and other estimated expenses of the offering. Net proceeds were used to pay a portion of the cash consideration and the fees and expenses in connection with the Company’s acquisition of Covance. Pursuant to the bridge facility commitment letter, upon the Company’s issuance of the Acquisition Notes the remaining $2.85 billion 364-day unsecured debt bridge tranche under the senior unsecured bridge term loan credit facility was terminated.

On February 13, 2015, the Company entered into a 60-day cash bridge term loan credit facility in the principal amount of $400.0 million for the purpose of financing a portion of the cash consideration and the fees and expenses in connection with the transactions contemplated by the Merger Agreement. The 60-day cash bridge term loan credit facility was entered into on the terms set forth in the bridge facility commitment letter for the $400.0 million 60-day cash bridge tranche. The 60-day cash bridge term loan credit facility was advanced in full on February 19, 2015, the date of the Company’s completion of the Acquisition.

The Company’s lower cash balance and increased indebtedness resulting from the acquisition financing could adversely affect its business. In particular, it could increase the Company’s vulnerability to sustained, adverse macroeconomic weakness, limit its ability to obtain further financing and limit its ability to pursue certain operational and strategic opportunities.

It may be difficult to integrate the business of Covance into the Company’s current business and the Company may fail to realize the anticipated revenue growth expected from the transaction, which could adversely affect its operating results and the market price of its common stock.

If the Company experiences greater than anticipated costs to integrate Covance Drug Development into its existing operations or is not able to achieve the anticipated benefits of the acquisition, its business and results of operations could be negatively affected. In addition, it is possible that the ongoing integration process could result in the loss of key employees, errors or delays in systems implementation, the disruption of the Company’s ongoing business or inconsistencies in standards, controls, procedures and policies that adversely affect the Company’s ability to maintain relationships with customers and employees or to achieve the anticipated benefits of the acquisition. Integration efforts also may divert management attention and resources.

These integration matters may have an adverse effect on the Company, particularly during any transition period. In addition, although Covance Drug Development is subject to many of the same risks and uncertainties that the Company faces in its business, the acquisition of Covance also involves the Company entering new product and services areas, markets and industries, which presents risks resulting from the Company’s relative inexperience in these new areas. Covance business’s laboratory testing business could react differently to economic and other external factors than the Company’s. The Company faces the risk that it will not be successful with these new products and services or in these new markets.

The success of the transaction will depend, in significant part, on the Company’s ability to successfully integrate the acquired business and realize the anticipated benefits to be derived from incorporating Covance Drug Development into its operations. The Company believes that the acquisition will provide an opportunity for revenue growth in development and commercialization of drugs and diagnostics, nutritional analysis and other areas, including a number of new business areas for the Company. Actual revenue growth, if any, may be lower than the Company expects and may take longer to achieve than anticipated, and expenses may be higher than the Company expects. If the Company is not able to achieve the anticipated benefits of the acquisition, the value of its common stock may be adversely affected.

The Company has made certain assumptions relating to the Covance acquisition that may prove to be materially inaccurate.

The Company has made certain assumptions relating to the Covance acquisition that may prove to be materially inaccurate, including as a result of the failure to realize the expected benefits of the acquisition, a longer acquisition and transition process than expected, higher than expected transaction and integration costs and unknown liabilities, or general economic and business conditions that could adversely affect the combined company following the acquisition. These assumptions relate to numerous matters, including:

• the Company’s assessments of the asset quality and value of Covance and its assets;

• projections of the business and Covance Drug Development's future financial performance;



• the Company’s ability to realize synergies and the timeline for doing so;

• acquisition costs, including restructuring charges and transaction costs;

- the Company’s ability to develop, maintain and deepen relationships with Covance Drug Development’s customers; and

• other financial and strategic risks of the acquisition.

If one or more of these assumptions are incorrect, it could have a material adverse effect on the Company’s business and operating results, and the expected benefits from the acquisition may not be realized.

## The Company incurred significant transaction and acquisition-related costs in connection with the Acquisition.

The Company has incurred and expects to continue to incur a number of non-recurring costs associated with the Acquisition. These costs and expenses include fees paid to financial, legal and accounting advisors, facilities and systems consolidation costs, severance and other potential employment-related costs, including payments that may be made to certain Covance business' executives, filing fees, printing expenses and other related charges. There are also a large number of processes, policies, procedures, operations, technologies and systems that the Company intends to integrate in connection with the Acquisition and the integration of the two companies' businesses. While the Company has assumed that a certain level of expenses will be incurred in connection with the Acquisition and the other transactions contemplated by the Merger Agreement, there are many factors beyond its control that could affect the total cost or the timing of the integration and implementation expenses.

There may also be additional and significant unanticipated costs in connection with the Acquisition that the Company may not be able to recoup. These costs and expenses could reduce the realization of efficiencies, strategic benefits and additional income the Company expects to achieve from the Acquisition. Although the Company believes that these expected benefits will offset the transaction expenses and implementation costs over time, a net benefit may not be achieved in the near term or at all.

The Acquisition may not be accretive, and may be dilutive, to the Company's earnings per share, which may negatively affect the market price of the Company's common stock.

Because shares of the Company's common stock were issued in the Acquisition, it is possible that the Acquisition will be dilutive to the Company's earnings per share, which could negatively affect the market price of shares of the Company's common stock. In addition, future events and conditions could increase the dilution of the Company's earnings as determined under generally accepted accounting principles ("GAAP") that is currently projected, including adverse changes in market conditions, additional transaction and integration-related costs and other factors such as the failure to realize some or all of the benefits anticipated in the Acquisition. Any dilution of, or delay of any accretion to, the Company's earnings per share, should cause the price of shares of the Company's common stock to decline or grow at a reduced rate.

Covance Drug Development is subject to uncertainties related to the acquisition that could adversely affect its financial results and ability to retain key employees.

Uncertainty about the effect of the acquisition on Covance Drug Development's customers, employees or suppliers may have an adverse effect on Covance. Although Covance Drug Development has taken steps to reduce any adverse effects, these uncertainties may impair its ability to attract, retain and motivate key personnel until the acquisition is completed and for a period of time thereafter, and could cause disruptions in its relationships with customers, suppliers and other parties with which it deals.

In particular, the Company considers Covance Drug Development's strong management team an attractive aspect of Covance. The loss of members of Covance Drug Development's senior management team could have an adverse effect on the Company's ability to operate Covance Drug Development and integrate it into the Company's consolidated operations. Retention of these key members may be particularly challenging prior to and even for a period after the completion of the acquisition, as employees may experience uncertainty about their future roles. If, despite retention and recruiting efforts, key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with Covance Drug Development, its business operations and financial results could be adversely affected.

The Company also expects that matters relating to the acquisition and integration-related issues will place a significant burden on the Company's and Covance Drug Development's management, employees and internal resources, which could otherwise have been devoted to other business opportunities and improvements.



Changes in government regulation or in practices relating to the pharmaceutical industry could decrease the need for certain services that Covance Drug Development provides.

Following the Company’s acquisition of Covance, a portion of its business involves assisting pharmaceutical and biotechnology companies navigate the regulatory drug approval process. 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 Covance Drug Development has difficulty satisfying or that make its service less competitive, could eliminate or substantially reduce the demand for its services. Also, if government efforts to contain drug costs impact pharmaceutical and biotechnology company profits from new drugs, some of Covance Drug Development’s customers may spend less, or reduce their growth in spending on research and development. If health insurers were to change their practices with respect to reimbursement for pharmaceutical products, some of Covance Drug Development’s customers may spend less, or reduce their growth in spending on research and development.

## Covance Drug Development’s revenues depend on the pharmaceutical and biotechnology industries.

Covance Drug Development's revenues depend greatly on the expenditures made by the pharmaceutical and biotechnology industries in research and development. In some instances, companies in these industries are reliant on their ability to raise capital in order to fund their research and development projects. Accordingly, economic factors and industry trends that affect Covance Drug Development's clients in these industries also affect Covance Drug Development. If companies in these industries were to reduce the number of research and development projects they conduct or outsource, whether through inability to raise capital, industry trends, economic conditions or otherwise, Covance Drug Development could be materially adversely affected.

Covance Drug Development may bear financial losses because many of its contracts are of a fixed price nature and may be delayed or terminated or reduced in scope for reasons beyond its control.

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

• the failure of products to satisfy safety requirements;

• unexpected or undesired results of the products;

• insufficient patient enrollment;

• insufficient investigator recruitment;

• the client’s decision to terminate the development of a product or to end a particular study; and

• Covance Drug Development's failure to perform properly its duties under the contract.

The loss, reduction in scope or delay of a large contract or the loss, delay or conclusion of multiple contracts could materially adversely affect Covance Drug Development, although its contracts often entitle it to receive the costs of winding down the terminated projects, as well as all fees earned up to the time of termination.

## Covance Drug Development operates in a highly competitive industry.

Competitors in the contract research organization industry range from small, limited-service providers to full service global contract research organizations. Covance Drug Development's main competition consists of in-house departments of pharmaceutical companies, full-service and functional contract research organizations, and, to a lesser degree, universities and teaching hospitals. Covance Drug Development competes on a variety of factors, including:

• reputation for on-time quality performance and regulatory compliance;

• expertise and experience in specific areas;

• scope of service offerings;

• strengths in various geographic markets;

• price;

• technological expertise and efficient drug development processes;

• quality of facilities;

• ability to acquire, process, analyze and report data in an accurate manner;

• ability to manage large-scale clinical trials both domestically and internationally;

• expertise and experience in market access services; and

• size.

For instance, certain of Covance Drug Development's services have from time-to-time experienced periods of increased price competition which had an adverse effect on a segment's profitability and consolidated net revenues and net income.

There is competition among contract research organizations for both clients and potential acquisition candidates. Additionally, entities considering entering the contract research organization industry will find few barriers to entry, thus further increasing



possible competition. These competitive pressures may affect the attractiveness of Covance Drug Development's services and could adversely affect its financial results and the financial results of the Company.

## Contract research services create a risk of liability.

In contracting to work on drug development trials and studies, Covance Drug Development faces a range of potential liabilities, including:

• errors or omissions that create harm during a trial to study volunteers or after trial to consumers of drug after regulatory approval of the drug;

- general risks associated with clinical pharmacology facilities, including negative consequences from the administration of drugs to clinical trial participants or the professional malpractice of clinical pharmacology medical care providers;

• errors or omissions from tests conducted for the agricultural, food, beverage and dietary supplement industries;

- risks that animals in Covance Drug Development's breeding facilities may be infected with diseases that may be harmful and even lethal to themselves and humans despite preventive measures contained in Covance business policies, including those for the quarantine and handling of imported animals; and

- errors and omissions during a trial that may undermine the usefulness of a trial or data from the trial or study or may delay the entry of a drug to the market.

Covance Drug Development also contracts with physicians, also referred to as investigators, to conduct the clinical trials to test new drugs on human volunteers. These tests can create a risk of liability for personal injury or death to volunteers, resulting from negative reactions to the drugs administered or from professional malpractice by third party investigators.

While Covance Drug Development endeavors to include in its contracts provisions entitling it to be indemnified or entitling it to a limitation of liability, these provisions do not uniformly protect Covance Drug Development against liability arising from certain of its own actions, such as negligence or misconduct. Covance Drug Development could be materially and adversely affected if it were required to pay damages or bear the costs of defending any claim that is not covered by a contractual indemnification provision or in the event that a party who must indemnify it does not fulfill its indemnification obligations, or in the event that the damages and costs exceed Covance Drug Development insurance coverage. There can be no assurance that Covance Drug Development will be able to maintain sufficient insurance coverage on terms acceptable to it.

## Covance Drug Development revenues and earnings are exposed to exchange rate fluctuations.

Covance Drug Development derives a large portion of its net revenues from international operations. Since the Company's consolidated financial statements are denominated in U.S. dollars, fluctuations in exchange rates from period to period will have an impact on reported results. In addition, in certain circumstances, Covance Drug Development may incur costs in one currency related to its services or products for which it is paid in a different currency. As a result, factors associated with international operations, including changes in foreign currency exchange rates, could significantly affect Covance Drug Development's results of operations, financial condition and cash flows.

## Actions of animal rights extremists may affect business.

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

Animal populations may suffer diseases that can damage Covance Drug Development's inventory, harm its reputation, result in decreased sales of research products or result in other liability.

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

## Item 1B. UNRESOLVED STAFF COMMENTS

None.



The Company operates through a national network of primary laboratories, branches, PSCs and STAT laboratories. The table below summarizes certain information as to the Company’s principal operating and administrative facilities as of December 31, 2014.

All of the Company’s primary laboratory facilities have been built or improved for the single purpose of providing clinical laboratory testing services. The Company believes that these facilities are suitable and adequate and have sufficient production capacity for its currently foreseeable level of operations. The Company believes that if it were unable to renew a lease or if a lease



were to be terminated on any of the facilities it presently leases, it could find alternate space at competitive market rates and readily relocate its operations to such new locations without material disruption to its operations.

## Item 3. LEGAL PROCEEDINGS

The Company is involved from time to time in various claims and legal actions, including arbitrations, class actions, and other litigation (including those described in more detail below), arising in the ordinary course of business. Some of these actions involve claims that are substantial in amount. These matters include, but are not limited to, intellectual property disputes, professional liability, employee-related matters, and inquiries, including subpoenas and other civil investigative demands, from governmental agencies, Medicare or Medicaid payers and managed care payers reviewing billing practices or requesting comment on allegations of billing irregularities that are brought to their attention through billing audits or third parties. The Company receives civil investigative demands or other inquiries from various governmental bodies in the ordinary course of its business. Such inquiries can relate to the Company or other health care providers. The Company works cooperatively to respond to appropriate requests for information.

The Company is also named from time to time in suits brought under the qui tam provisions of the False Claims Act and comparable state laws. These suits typically allege that the Company has made false statements and/or certifications in connection with claims for payment from federal or state health care programs. They may remain under seal (hence, unknown to the Company) for some time while the government decides whether to intervene on behalf of the qui tam plaintiff. Such claims are an inevitable part of doing business in the health care field today.

The Company believes that it is in compliance in all material respects with all statutes, regulations and other requirements applicable to its clinical laboratory operations. The clinical laboratory testing industry is, however, subject to extensive regulation, and the courts have not interpreted many of the applicable statutes and regulations. There can be no assurance, therefore, that such statutes and regulations will not be interpreted or applied by a prosecutorial, regulatory or judicial authority in a manner that would adversely affect the Company. Potential sanctions for violation of these statutes and regulations include significant fines, the loss of various licenses, certificates and authorizations and/or exclusion from participation in government programs.

Many of the current claims and legal actions against the Company are in preliminary stages, and many of the cases seek an indeterminate amount of damages. The Company records an aggregate legal reserve, which is determined using actuarial calculations based on historical loss rates and assessment of trends experienced in settlements and defense costs. In accordance with FASB Accounting Standards Codification Topic 450 “Contingencies”, the Company establishes reserves for judicial, regulatory, and arbitration matters outside the aggregate legal reserve if and when those matters present loss contingencies that are both probable and estimable and would exceed the aggregate legal reserve. When loss contingencies are not both probable and estimable, the Company does not establish separate reserves.

The Company is unable to estimate a range of reasonably probable loss for cases described in more detail below in which damages either have not been specified or, in the Company's judgment, are unsupported and/or exaggerated and (i) the proceedings are in early stages; (ii) there is uncertainty as to the outcome of pending appeals or motions; (iii) there are significant factual issues to be resolved; and/or (iv) there are novel legal issues. For these cases, however, the Company does not believe, based on currently available information, that the outcomes of these proceedings will have a material adverse effect on the Company's financial condition, though the outcomes could be material to the Company's operating results for any particular period, depending, in part, upon the operating results for such period.

As previously reported, the Company reached a settlement in the previously disclosed lawsuit, California ex rel. Hunter Laboratories, LLC et al. v. Quest Diagnostics Incorporated, et al. ("Hunter Labs Settlement Agreement"), to avoid the uncertainty and costs associated with prolonged litigation. Pursuant to the executed settlement agreement, the Company recorded a litigation settlement expense of $34.5 million in the second quarter of 2011 (net of a previously recorded reserve of $15.0 million) and paid the settlement amount of $49.5 million in the third quarter of 2012. The Company also agreed to certain reporting obligations regarding its pricing for a limited time period and, at the option of the Company in lieu of such reporting obligations, to provide Medi-Cal with a discount from Medi-Cal's otherwise applicable maximum reimbursement rate from November 1, 2011 through October 31, 2012. In June of 2012, the California legislature enacted Assembly Bill No. 1494, Section 9 of which directed the Department of Health Care Services ("DHCS") to establish new reimbursement rates for Medi-Cal clinical laboratory services that will be based on payments made to California clinical laboratories for similar services by other third-party payers. With stakeholder input, DHCS established data elements and a format for laboratories to report payment data from comparable third-party payers. Laboratories reported payment data to DHCS in the summer of 2013. On March 28, 2014, Assembly Bill No. 1124 extended the implementation deadline of new regulations until June 30, 2016. Assembly Bill No. 1494 provides that until the new rates are set through this process, Medi-Cal payments for clinical laboratory services will be reduced (in addition to a 10% payment reduction imposed by Assembly Bill No. 97 in 2011) by “up to 10 percent” for tests with dates of service on or after July



1, 2012, with a cap on payments set at 80% of the lowest maximum allowance established under the federal Medicare program. Under the terms of the Hunter Labs Settlement Agreement, the enactment of this California legislation terminates the Company's reporting obligations (or obligation to provide a discount in lieu of reporting) under that agreement. In December 2014, DCHS announced at a stakeholder meeting the results of its analysis of payment data reported by laboratories in 2013 and its proposed rate methodology, on which it solicited stakeholder comments. The Company objected to the proposal by DHCS to exclude the new rate calculations data on payments from comparable third-party payers exceeding 80% of Medicare reimbursement amounts and its proposal to impose a 10% payment reduction enacted in Assembly Bill No. 97 after calculation of the new rates. In January 2015, after receiving stakeholder comments, DHCS instructed laboratories to submit 2014 payment data by March 27, 2015, which DHCS will use (except for data on payment amounts exceeding 80% of Medicare reimbursement) to establish new rates effective July 1, 2015, to which DHCS intends to apply the 10% payment reduction referenced in Assembly Bill No. 97. While the Company continues to dispute this methodology, taken together, these changes are not expected to have a material impact on the Company's consolidated revenues or results of operations.

As previously reported, the Company responded to an October 2007 subpoena from the United States Department of Health & Human Services Office of Inspector General's regional office in New York. On August 17, 2011, the Southern District of New York unsealed a False Claims Act lawsuit, United States of America ex rel. NPT Associates v. Laboratory Corporation of America Holdings, which alleges that the Company offered United Healthcare kickbacks in the form of discounts in return for Medicare business. The Plaintiff's third amended complaint further alleges that the Company's billing practices violated the false claims acts of fourteen states and the District of Columbia. The lawsuit seeks actual and treble damages and civil penalties for each alleged false claim, as well as recovery of costs, attorney's fees, and legal expenses. Neither the U.S. government nor any state government has intervened in the lawsuit. The Company's Motion to Dismiss was granted in October 2014. The Company intends to vigorously defend the lawsuit should it proceed further.

In addition, the Company has received various subpoenas since 2007 related to Medicaid billing. In October 2009, the Company received a subpoena from the State of Michigan Department of Attorney General seeking documents related to its billing to Michigan Medicaid. In June 2010, the Company received a subpoena from the State of Florida Office of the Attorney General requesting documents related to its billing to Florida Medicaid. In October 2013, the Company received a civil investigative demand from the State of Texas Office of the Attorney General requesting documents related to its billing to Texas Medicaid. The Company is cooperating with these requests.

On November 4, 2013, the State of Florida through the Office of the Attorney General filed an Intervention Complaint in a False Claims Act lawsuit, State of Florida ex rel. Hunter Laboratories, LLC and Chris Riedel v. Quest Diagnostics Incorporated, et al. in the Circuit Court for the Second Judicial Circuit for Leon County. The complaint, originally filed by a competitor laboratory, alleges that the Company overcharged Florida’s Medicaid program. The lawsuit seeks actual and treble damages and civil penalties for each alleged false claim, as well as recovery of costs, attorney’s fees, and legal expenses. On January 3, 2014, the Company filed a Petition for the Administrative Determination of the Invalidity of an Existing Rule against the Agency for Health Care Administration (“AHCA”). The Petition sought the invalidity of Rule 59G-5.110(2) of the Florida Administrative Code, which was relied upon by the Attorney General in its Intervention Complaint. On March 28, 2014, an Administrative Law Judge for the State of Florida Division of Administrative Hearings issued an order finding that Rule 59G-5.110(2) of the Florida Administrative Code was invalid. In the interim, the Attorney General filed a First Amended Intervention Complaint on January 30, 2014, which seeks actual and treble damages and civil penalties for alleged false claims, as well as recovery of costs, attorney’s fees, and legal expenses, for allegedly overcharging Florida’s Medicaid program. The Company’s Motion to Dismiss was denied in February 2015. The Company will vigorously defend the lawsuit.

On May 2, 2013, the Company was served with a False Claims Act lawsuit, State of Georgia ex rel. Hunter Laboratories, LLC and Chris Riedel v. Quest Diagnostics Incorporated, et al., filed in the State Court of Fulton County, Georgia. The lawsuit, filed by a competitor laboratory, alleges that the Company overcharged Georgia's Medicaid program. The case has been removed to the United States District Court for the Northern District of Georgia. The lawsuit seeks actual and treble damages and civil penalties for each alleged false claim, as well as recovery of costs, attorney's fees, and legal expenses. The government filed a notice declining to intervene in the case. On March 14, 2014, the Company's Motion to Dismiss was granted. The Plaintiffs' motion seeking leave to repeal their complaint was granted. The Company's Motion to Dismiss the First Amended Complaint is pending. The Company will vigorously defend the lawsuit.

On August 19, 2013, the Company was served with a False Claims Act lawsuit, Commonwealth of Virginia ex rel. Hunter Laboratories, LLC and Chris Riedel v. Quest Diagnostics Incorporated, et al., filed in the Circuit Court of Fairfax County, Virginia. The lawsuit, filed by a competitor laboratory, alleged that the Company overcharged Virginia’s Medicaid program. The case was removed to the United States District Court for the Eastern District of Virginia. The lawsuit sought actual and treble damages and civil penalties for each alleged false claim, as well as recovery of costs, attorney’s fees, and legal expenses. The government filed a notice declining to intervene in the case. The Company’s Motion to Dismiss was granted and the



Plaintiff's were granted the right to seek relief to repeal their complaint. An amended complaint was filed and the Company's Motion to Dismiss was granted in March of 2014. The Plaintiffs filed a notice of appeal. The parties resolved the lawsuit while it was pending an appeal.

In October 2011, a putative stockholder of the Company made a letter demand through his counsel for inspection of documents related to policies and procedures concerning the Company's Board of Directors' oversight and monitoring of the Company's billing and claim submission process. The letter sought documents prepared for or by the Board regarding allegations from the California ex rel. Hunter Laboratories, LLC et al. v. Quest Diagnostics Incorporated, et al., a lawsuit that was settled in 2011, and documents reviewed and relied upon by the Board in connection with the settlement. The Company responded to the request pursuant to Delaware law.

On November 18, 2011, the Company received a letter from U.S. Senators Baucus and Grassley requesting information regarding the Company's relationships with its largest managed care customers. The letter requested information about the Company's contracts and financial data regarding its managed care customers. Company representatives met with Senate Finance Committee staff after receiving the request and subsequently produced documents in response. The Company will continue to cooperate with any further requests for information.

On February 27, 2012, the Company was served with a False Claims Act lawsuit, United States ex rel. Margaret Brown v. Laboratory Corporation of America Holdings and Tri-State Clinical Laboratory Services, LLC, filed in the United States District Court for the Southern District of Ohio, Western Division. The Company owned 50% of Tri-State Clinical Laboratory Services, LLC, which was dissolved in June 2011 pursuant to a voluntary petition under Chapter 7 of Title 11 of the United States Code. The lawsuit alleges that the defendants submitted false claims for payment for laboratory testing services performed as a result of financial relationships that violated the federal Stark and Anti-Kickback Laws. The lawsuit seeks actual and treble damages and civil penalties for each alleged false claim, as well as recovery of costs, attorney's fees, and legal expenses. The U.S. government has not intervened in the lawsuit. The parties have reached a settlement in principle, but the Company will vigorously defend the lawsuit if the settlement is not finalized.

On June 7, 2012, the Company was served with a putative class action lawsuit, Yvonne Jansky v. Laboratory Corporation of America, et al., filed in the Superior Court of the State of California, County of San Francisco. The lawsuit alleges that the defendants committed unlawful and unfair business practices, and violated various other state laws by changing screening codes to diagnostic codes on laboratory test orders, thereby resulting in customers being responsible for co-payments and other debts. The lawsuit seeks injunctive relief, actual and punitive damages, as well as recovery of attorney's fees, and legal expenses. The Company will vigorously defend the lawsuit.

On June 7, 2012, the Company was served with a putative class action lawsuit, Ann Baker Pepe v. Genzyme Corporation and Laboratory Corporation of America Holdings, filed in the United States District Court for the District of Massachusetts. The lawsuit alleged that the defendants failed to preserve DNA samples allegedly entrusted to the defendants and thereby breached a written agreement with plaintiff and violated state laws. The lawsuit sought injunctive relief, actual, double and treble damages, as well as recovery of attorney's fees and legal expenses. The lawsuit was resolved and a consent judgment was approved by the Court in January 2015.

On August 24, 2012, the Company was served with a putative class action lawsuit, Sandusky Wellness Center, LLC, et al. v. MEDTOX Scientific, Inc., et al., filed in the United States District Court for the District of Minnesota. The complaint alleges that on or about February 21, 2012, the defendants violated the federal Telephone Consumer Protection Act ("TCPA") by sending unsolicited facsimiles to Plaintiff and more than 39 other recipients without the recipients' prior express permission or invitation. The lawsuit seeks the greater of actual damages or the sum of $0.0005 for each violation, subject to trebling under the TCPA, and injunctive relief. In September of 2014, Plaintiff's Motion for Class Certification was denied. In January of 2015, the Company's Motion for Summary Judgment on the remaining individual claim was granted. Plaintiff has filed a notice of appeal. The Company will vigorously defend the lawsuit.

The Company was a defendant in two separate putative class action lawsuits, Christine Bohlander v. Laboratory Corporation of America, et al., and Jemuel Andres, et al. v. Laboratory Corporation of America Holdings, et al., related to overtime pay. After the filing of the two lawsuits on July 8, 2013, the Bohlander lawsuit was consolidated into the Andres lawsuit, and the consolidated lawsuit is now pending in the Superior Court of California for the County of Los Angeles. In the consolidated lawsuit, the Plaintiffs allege on behalf of similarly situated phlebotomists and couriers that the Company failed to pay overtime, failed to provide meal and rest breaks, and committed other violations of the California Labor Code. Plaintiffs have subsequently filed an amended complaint. The complaint seeks monetary damages, civil penalties, costs, injunctive relief, and attorney's fees. The parties have reached a tentative class settlement, which is subject to Court approval. The Court will hold a hearing on the merits of the settlement terms on February 26, 2015. If the settlement is not approved by the Court, the Company intends to vigorously defend the lawsuit.



The Company is also a defendant in two additional putative class action lawsuits alleging similar claims to the Bohlander/Andres consolidated lawsuit. The lawsuit Rachel Rabanes v. California Laboratory Sciences, LLC, et al., was filed in April 2014 in the Superior Court of California for the County of Los Angeles, and the lawsuit Rita Varsam v. Laboratory Corporation of America DBA LabCorp, was filed in June 2014 in the Superior Court of California for the County of San Diego. In these lawsuits, the Plaintiffs allege on behalf of similarly situated employees that the Company failed to pay overtime, failed to provide meal and rest breaks, and committed other violations of the California Labor Code. The complaints seek monetary damages, civil penalties, costs, injunctive relief, and attorney's fees. The Company will vigorously defend these lawsuits.

On December 17, 2010, the Company was served with a lawsuit, Oliver Wuth, et al. v. Laboratory Corporation of America, et al., filed in the State Superior Court of King County, Washington. The lawsuit alleges that the Company was negligent in the handling of a prenatal genetic test order that allegedly resulted in the parents being given incorrect information. The matter was tried before a jury beginning on October 21, 2013. On December 10, 2013, the jury returned a verdict in in plaintiffs' favor in the amount of $50.0 million, with 50% of liability apportioned to the Company and 50% of liability apportioned to co-defendant Valley Medical Center. The Company filed post-judgment motions for a new trial, which were denied, and is vigorously pursuing an appeal of the judgment on multiple grounds. The Company carries self-insurance reserves and excess liability insurance sufficient to cover the potential liability in this case.

On July 3, 2012, the Company was served with a lawsuit, John Wisekal, as Personal Representative of the Estate of Darien Wisekal v. Laboratory Corporation of America Holdings and Glenda C. Mixon, filed in the Circuit Court of the Fifteenth Judicial Circuit in and for Palm Beach County, Florida. The lawsuit alleges that the Company misread a Pap test. The case was removed to the United States District Court for the Southern District of Florida. The matter was tried before a jury beginning on April 1, 2014. On April 17, 2014, the jury returned a verdict in Plaintiff's favor in the amount of $20.8 million, with non-economic damages reduced by 25% to account for the Plaintiff's negligence, for a final verdict of $15.8 million. The Company filed post-trial motions. On July 28, 2014, the Court granted the Company's motion for remittitur and reduced the jury's non-economic damages award to $5.0 million, reduced by 25.0% for the Plaintiff's negligence. Accordingly, the total judgment is $4.4 million. In December of 2014, the Court granted Plaintiff's Motion to Certify the remittitur order for interlocutory appeal, and stayed the case pending the Eleventh Circuit Court of Appeal's review of the Plaintiff's challenge to the reduction in the judgment.

On July 9, 2014, the Company was served with a putative class action lawsuit, Christopher W. Legg, et al. v. Laboratory Corporation of America, filed in the United States District Court for the Southern District of Florida. The complaint alleges that the Company violated the Fair and Accurate Credit Transactions Act (“FACTA”) by allegedly providing credit card expiration date information on an electronically printed credit card receipt. The lawsuit seeks statutory and punitive damages, injunctive relief, and attorney’s fees. The Company will vigorously defend the lawsuit.

In October 2014, the Company became aware of, but was not served with, a False Claims Act lawsuit, United States of America and State of California ex rel. Elisa Martinez v. Quest Diagnostics Incorporated, et al., filed in the United States District Court for the Eastern District of California. The lawsuit alleged that Quest and the Company submitted false claims to the United States and the State of California for duplicative lab tests. The lawsuit sought actual and treble damages and civil penalties for each alleged claim, as well as recovery of costs, attorney's fees, and legal expenses. Neither the United States government nor the State of California intervened in the lawsuit. In January of 2015, Plaintiffs filed a First Amended Complaint and the Company is no longer a defendant in the lawsuit.

Prior to the consummation of the Company’s acquisition of LipoScience, purported stockholders of LipoScience filed four putative class action lawsuits against LipoScience, members of the LipoScience board of directors, the Company and Bear Acquisition Corp., a wholly owned subsidiary of the Company, in the Delaware Court of Chancery and, with respect to one of the lawsuits, in the Superior Court of Wake County, North Carolina. The lawsuits alleged breach of fiduciary duty and/or other violations of state law arising out of the proposed acquisition. Each suit sought, among other things, injunctive relief enjoining the merger. On October 23, 2014, the case in North Carolina was voluntarily dismissed without prejudice by the Plaintiff. On October 29, 2014, the Delaware Court of Chancery consolidated the four actions under the caption In re LipoScience, Inc. Stockholder Litigation, Consolidated C.A. No. 10252-VCP (the “Consolidated Action”). On November 7, 2014, the Consolidated Action plaintiffs entered into a memorandum of understanding with the defendants regarding a settlement of the Consolidated Action. In connection with the settlement, the parties agreed that LipoScience would make certain additional disclosures to its stockholders. Subject to the completion of certain confirmatory discovery by counsel, entry by the parties into a stipulation of settlement and customary conditions, including court approval, the settlement will resolve all of the claims that were or could have been brought, including all claims relating to the merger.

On November 19, 2014, the Company entered into a definitive merger agreement to acquire Covance, Inc. (“Covance”) for approximately $6.2 billion in cash and Company common stock. The transaction closed on February 19, 2015. Prior to the closing



of the transaction, purported stockholders of Covance filed two putative class action lawsuits, one in the Delaware Court of Chancery, and the other in Mercer County, New Jersey, against Covance, members of the Covance board of directors, the Company and Neon Merger Sub, Inc., a wholly owned subsidiary of the Company. The lawsuits alleged breach of fiduciary duty and/or other violations of state law arising out of the proposed acquisition. Each suit sought, among other things, injunctive relief enjoining the merger. On January 21, 2015, the case in New Jersey was voluntarily dismissed without prejudice by the Plaintiff. On February 9, 2015, the Plaintiffs in the Delaware case entered into a memorandum of understanding with the Defendants regarding a settlement. In connection with the settlement, the parties agreed that Covance would make additional disclosures to its stockholders. Subject to the entry by the parties into a stipulation of settlement and customary conditions, including court approval, the settlement will resolve all the claims that were or could have been brought, including all claims relating to the merger.

In December 2014, the Company received a Civil Investigative Demand issued pursuant to the federal False Claims Act from the U.S. Attorney’s Office for South Carolina, which requests information regarding remuneration and services provided by the Company to physicians who also received draw and processing/handling fees from competitor laboratories Health Diagnostic Laboratory, Inc. and Singulex, Inc. The Company is cooperating with the request.

Under the Company's present insurance programs, coverage is obtained for catastrophic exposure as well as those risks required to be insured by law or contract. The Company is responsible for the uninsured portion of losses related primarily to general, professional and vehicle liability, certain medical costs and workers' compensation. The self-insured retentions are on a per occurrence basis without any aggregate annual limit. Provisions for losses expected under these programs are recorded based upon the Company's estimates of the aggregated liability of claims incurred. As of December 31, 2014, the Company had provided letters of credit aggregating approximately $42.5 million, primarily in connection with certain insurance programs. The Company's availability under its Revolving Credit Facility is reduced by the amount of these letters of credit.

(a) During 2014, the Company recorded net restructuring charges of $17.8. The charges were comprised of $10.5 in severance and other personnel costs and $8.4 in facility-related costs primarily associated with facility closures and general integration initiatives. These charges were offset by the reversal of previously established reserves of $0.4 in unused severance and $0.7 in unused facility-related costs.

(b) During 2013, the Company recorded net restructuring charges of $21.8. The charges were comprised of $15.4 in severance and other personnel costs and $9.5 in facility-related costs primarily associated with facility closures and general integration initiatives. These charges were offset by the reversal of previously established reserves of $0.7 in unused severance and $2.4 in unused facility-related costs.

(c) During 2012, the Company recorded net restructuring charges of $25.3. The charges were comprised of $16.2 in severance and other personnel costs and $19.6 in facility-related costs primarily associated with the ongoing integration activities of Orchid and the Integrated Genetics business (formerly Genzyme Genetics) and costs associated with the previously announced termination of an executive vice president. These charges were offset by the reversal of previously established reserves of $6.3 in unused severance and $4.2 in unused facility-related costs.

(d) During 2011, the Company recorded net restructuring charges of $44.6. Of this amount, $27.4 related to severance and other personnel costs, and $22.0 primarily related to facility-related costs associated with the ongoing integration of certain acquisitions including Genzyme Genetics and Westcliff Medical Laboratories, Inc. ("Westcliff"). These charges were offset by restructuring credits of $4.8 resulting from the reversal of unused severance and facility



closure liabilities. In addition, the Company recorded fixed assets impairment charges of $18.9 primarily related to equipment, computer systems and leasehold improvements in closed facilities. The Company also recorded special charges of $14.8 related to the write-off of certain assets and liabilities related to an investment made in prior years, along with a $2.6 write-off of an uncollectible receivable from a past installment sale of one of the Company's lab operations.

Following the closing of its acquisition of Orchid in mid-December 2011, the Company recorded a net $2.8 loss on its divestiture of certain assets of Orchid's U.S. government paternity business, under the terms of the agreement reached with the U.S. Federal Trade Commission. This non-deductible loss on disposal was recorded in Other Income and Expense in the Company's Consolidated Statements of Operations and decreased net earnings for the twelve months ended December 31, 2011 by $2.8.

During 2010, the Company recorded net restructuring charges of $5.8 primarily related to work force reductions and the closing of redundant and underutilized facilities. In addition, the Company recorded a special charge of $6.2 related to the write-off of development costs incurred on systems abandoned during the year.

The Company incurred approximately $25.7 in professional fees and expenses in connection with the acquisition of Genzyme Genetics and other acquisition activity, including significant costs associated with the Federal Trade Commission’s review of the Company’s purchase of specified net assets of Westcliff. These fees and expenses are included in selling, general and administrative expenses for the year ended December 31, 2010.

The Company also incurred $7.0 of financing commitment fees (included in interest expense for the year ended December 31, 2010) in connection with the acquisition of Genzyme Genetics.

# MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (in millions)

## General

Net sales for 2014 increased 3.5% in comparison to 2013. The increase was the result of strong organic volume growth along with the benefit of fold-in acquisitions, which was partially offset by changes in test and payer mix. Total test volume (measured by number of requisitions) increased 5.3% year over year, and year over year revenue per requisition decreased 1.7% of which 0.4% was due to foreign currency translation with the remainder due to changes in test and payer mix.

During 2014 and 2013, the impact of weather reduced the Company's revenues by an estimated $40.0 and $12.7, respectively.

The Company has seen growth in the amount of its patient accounts receivable. A significant portion of the Company’s bad debt expense is related to accounts receivable from patients. The Company believes its current allowance for doubtful accounts is sufficient to properly record its accounts receivable at their estimated net realizable value. Should the shift towards increased patient responsibility continue, the Company may need to increase its allowance for doubtful accounts and bad debt expense in future periods.

On February, 19, 2015, the Company completed its acquisition of Covance Inc. (“Covance”), a leading drug development services company and a leader in nutritional analysis, for approximately $6,200.0. In connection with the transaction, the Company secured permanent financing, including a $1,000.0 5 year term loan and $2,900.0 in long term bonds, ranging from 5 years to 30 years. The weighted average interest rate on the $3,900.0 of long-term debt is approximately 3.15%, while the average maturity is approximately 12 years. As a result, the Company anticipates a significant increase in the total debt to consolidated EBITDA ratio for the combined company. In addition, the Company issued approximately 15.3 million shares of the Company’s common stock to the Covance shareholders. The Company expects to maintain an investment grade credit profile and intends to utilize its free cash flow to pay down debt and make small "fold-in" acquisitions.

Covance 2014 net revenues were approximately $2,500.0 and operating income margin was approximately 9.3%. Approximately 52.0% of Covance's net revenues are billed in currencies other than the U.S. dollar, with the Swiss franc, British pound, and the Euro representing approximately 70.0% of Covance's total foreign currency exposure. While the Company expects to achieve annual cost synergies in excess of $100.0 to be fully realized within three years of closing the transaction, 2015 results will be impacted by increased interest expense and lower margins from Covance.

The Company manages its operations through two reportable segments: the Clinical diagnostics laboratory segment, which includes core testing as well as genomic and esoteric testing, and the Other segment, which consists of the Company's non-U.S. clinical diagnostic laboratory operations in Ontario, Canada, which is reviewed separately by corporate management for the purposes of allocation of resources. As mentioned above, in Item 1, "Business," of this annual report, the Clinical diagnostics laboratory segment results of operations have been negatively impacted by reductions in payments for laboratory services, primarily from federal and state government entities. Operating results for the Other segment have declined as compared to 2013, primarily due to government reimbursement reductions, as well as the impact of the stronger U.S. dollar in 2014 as compared with 2013.

The discussion of the Company’s financial condition and results of operations set forth below does not reflect the operations or results of Covance, which will operate as Covance Drug Development. References in this Item 7 to the “Company” do not include Covance Drug Development, except where the circumstances clearly indicate otherwise.

## Seasonality

The majority of the Company’s testing volume is dependent on patient visits to physician offices and other providers of health care. Volume of testing generally declines during the year-end holiday periods and other major holidays. In addition, volume declines due to inclement weather may reduce net revenues and cash flows. Therefore, comparison of the results of successive periods may not accurately reflect trends or results from one year to the next.

The increase in net sales for the three years ended December 31, 2014 has been driven primarily by strong organic volume growth and the benefit of fold-in acquisitions made in all years in both of the Company's segments, along with growth in the Company's managed care business and toxicology testing, partially offset by test and payer mix. During 2014, the impact of weather reduced the Company's revenues by an estimated $40.0. The increase in revenue per requisition in core testing is the result of the number of tests per requisition and a change in the mix of testing within that category. The decline in revenue per requisition in genomic and esoteric testing is primarily a result of a change in the mix of tests within those categories.

During 2013, the impact of weather, reduced the Company's revenues by an estimated $12.7, of which $5.3 occurred in the fourth quarter. The 2013 decline in revenue per requisition in genomic and esoteric testing is a result of a change in mix of genetic and histology testing. Histology revenue per requisition was also impacted by payment reductions on the Medicare physician fee schedule. Further, revenue per requisition also decreased due to delays in payments and denials of coverage for existing tests by some payers after implementation of new molecular pathology codes at the beginning of the year and the implementation of sequestration on April 1, 2013.

Net sales of the Other segment were $329.4 for 2014 compared to $343.1 in 2013, a decrease of $13.7, or 4.0%. Net sales of the Other segment were negatively impacted by a stronger U.S. dollar in 2014 as compared with 2013 and 2012. In Canadian dollars, net sales of the Other segment for the twelve months ended December 31, 2014, 2013 and 2012 were CN$353.2 and CN$334.7, respectively.



<table><tr><td rowspan="2">Cost of Sales</td><td colspan="3">Years Ended December 31,</td><td colspan="2">Change</td></tr><tr><td>2014</td><td>2013</td><td>2012</td><td>2014</td><td>2013</td></tr><tr><td>Cost of sales</td><td>$ 3,808.5</td><td>$ 3,585.1</td><td>$ 3,421.7</td><td>6.2%</td><td>4.8%</td></tr><tr><td>Cost of sales as a % of sales</td><td>63.4%</td><td>61.7%</td><td>60.3%</td><td></td><td></td></tr></table>

Cost of sales (primarily laboratory and distribution costs) increased 6.2% in 2014 as compared with 2013 primarily due to increased test volumes and test mix changes. The increase in cost of sales as a percentage of net sales in 2014 as compared to 2013 is due to the increased number of tests per requisition. The increase in cost of sales as a percentage of net sales in 2013 as compared to 2012 is primarily due to lower revenues resulting from the Medicare fee reductions, the impact of delays and denials of coverage of molecular pathology codes and sequestration in 2013, as mentioned above.

Labor and testing supplies for the year ended December 31, 2014, comprise over 77.4% of the Company’s cost of sales. Cost of sales has increased over the three year period ended December 31, 2014 primarily due to overall growth in the Company's volume (including a 2.5% increase in the number of tests per requisition), the impact of acquisitions and increases in labor.

## Selling, General and Administrative Expenses

<table><tr><td rowspan="2"></td><td colspan="3">Years Ended December 31,</td><td colspan="2">Change</td></tr><tr><td>2014</td><td>2013</td><td>2012</td><td>2014</td><td>2013</td></tr><tr><td>Selling, general and administrative expenses</td><td>$ 1,198.2</td><td>$ 1,128.8</td><td>$ 1,114.6</td><td>6.1%</td><td>1.3%</td></tr><tr><td>SG&amp;A as a % of sales</td><td>19.9%</td><td>19.4%</td><td>19.7%</td><td></td><td></td></tr></table>

Selling, general and administrative expenses as a percentage of net sales increased to 19.9% in 2014 compared to 19.4% in 2013. The increase in selling, general and administrative expenses as a percentage of net sales is partially due to $13.8 in fees related to the Covance and LipoScience, Inc. acquisitions recorded in 2014. Additionally, bad debt expense increased to 4.6% of net sales in 2014 as compared to 4.4% of net sales in 2013. The Company also recorded $18.6 in consulting expenses (recorded in selling, general and administrative) relating to fees incurred as part of its business process improvement initiative as well as one-time CFO transition costs.

Selling, general and administrative expenses as a percentage of net sales decreased to 19.4% in 2013 compared to 19.7% in 2012. The decrease in selling, general and administrative expenses as a percentage of net sales was primarily due to $9.9 in fees related to the MEDTOX acquisition recorded in 2012 and to efficiencies from acquired operations that are being integrated into the Company's operating cost structure. Additionally, bad debt expense increased to 4.4% of net sales in 2013 as compared to 4.3% of net sales in 2012.

## Amortization of Intangibles and Other Assets

<table><tr><td rowspan="2"></td><td colspan="3">Years Ended December 31,</td><td colspan="2">Change</td></tr><tr><td>2014</td><td>2013</td><td>2012</td><td>2014</td><td>2013</td></tr><tr><td>Amortization of intangibles and other assets</td><td>$ 76.7</td><td>$ 81.7</td><td>$ 86.3</td><td>(6.1)%</td><td>(5.3)%</td></tr></table>

The decrease in amortization of intangibles and other assets over the three year period ended December 31, 2014 primarily reflects the net impact of acquisitions closed during all three years offset by adjustments to the fair value of deferred acquisition payments. During 2012, the Company recorded $6.2 in accelerated amortization relating to the termination of a licensing agreement.

## Restructuring and Other Special Charges

<table><tr><td rowspan="2"></td><td colspan="4">Years Ended December 31,</td></tr><tr><td>2014</td><td>2013</td><td>2012</td><td></td></tr><tr><td>Restructuring and other special charges</td><td>$ 17.8</td><td>$ 21.8</td><td>$ 25.3</td><td></td></tr></table>

During 2014, the Company recorded net restructuring charges of $17.8. The charges were comprised of $10.5 in severance and other personnel costs and $8.4 in facility-related costs primarily associated with general integration activities. These charges were offset by the reversal of previously established reserves of $0.4 in unused severance and $0.7 in unused facility-related costs.



In addition, during 2014, the Company recorded $18.6 in consulting expenses (recorded in selling, general and administrative expenses) relating to fees incurred as part of its business process improvement initiative as well as one-time CFO transition costs. The Company also recorded $10.8 of costs related to the Covance acquisition, of which $4.8 is included in selling, general and administrative expenses and $6.0 is included in interest expense.

During 2013, the Company recorded net restructuring charges of $21.8. The charges were comprised of $15.4 in severance and other personnel costs and $9.5 in facility-related costs primarily associated with general integration activities. These charges were offset by the reversal of previously established reserves of $0.7 in unused severance and $2.4 in unused facility related costs.

During 2012, the Company recorded net restructuring charges of $25.3. The charges were comprised of $16.2 in severance and other personnel costs and $19.6 in facility-related costs primarily associated with the ongoing integration of Orchid and Integrated Genetics Division (formerly Genzyme Genetics) and costs associated with the previously announced termination of an executive vice president. These charges were offset by the reversal of previously established reserves of $6.3 in unused severance and $4.2 in unused facility-related costs.

As part of the Clearstone integration, the Company also recorded a $6.9 loss on the disposal of one of its European subsidiaries in Other, net under Other income (expenses) during 2012.

During 2014, the Company announced Project Launchpad, which re-engineers the Company's systems and processes, leverages technological advancements and creates a sustainable, more efficient business model. The Company expects this initiative to drive savings in excess of $150.0 over the next three years, with associated one-time costs of approximately $30.0. The Company believes that any restructuring costs which may be incurred in future periods will be more than offset by subsequent savings realized from these potential actions and that any related restructuring charges will not have a material impact on the Company's operations or liquidity.

<table><tr><td rowspan="2">Interest Expense</td><td colspan="3">Years Ended December 31,</td><td colspan="3">Change</td></tr><tr><td>2014</td><td>2013</td><td>2012</td><td>2014</td><td>2013</td><td></td></tr><tr><td>Interest expense</td><td>$ 109.5</td><td>$ 96.5</td><td>$ 94.5</td><td>13.5%</td><td>2.1%</td><td></td></tr></table>

The increase in interest expense for 2014 as compared with 2013 is primarily due to the issuance of $700.0 of senior notes in November 2013, reductions in borrowings under the Company's former Revolving Credit Facility, and Covance-related financing activities. This increase was also partially offset by a decrease in interest expense on the Company's senior notes due 2020 as a result of entering into a fixed to floating interest rate swap in the third quarter of 2013. The new and former Revolving Credit Facilities and the Company's financing activities in connection with the Covance acquisition are described below under the heading "Liquidity, Capital Resources, and Financial Position."

The increase in interest expense for 2013 as compared with 2012 is primarily due to the issuance of $700.0 of senior notes in November 2013 and $1,000.0 of senior notes in August 2012, net of the payoff of the Company's 5.5% senior notes due 2013 and the reductions in borrowings under the former Revolving Credit Facility due to paydowns with proceeds from the 2012 and 2013 issuances. This increase was also partially offset by a decrease in interest expense on the senior notes due 2020 as a result of entering into a fixed to floating interest rate swap in the third quarter of 2013.

## Equity Method Income

<table><tr><td rowspan="2"></td><td colspan="3">Years Ended December 31,</td><td colspan="3">Change</td></tr><tr><td>2014</td><td>2013</td><td>2012</td><td>2014</td><td>2013</td><td></td></tr><tr><td>Equity method income</td><td>$ 14.3</td><td>$ 16.9</td><td>$ 21.4</td><td>(15.4)%</td><td>(21.0)%</td><td></td></tr></table>

Equity method income represents the Company's ownership share in joint venture partnerships along with equity investments in other companies in the health care industry. The decrease in income in 2014 compared to 2013 is primarily the result of a decline in profitability of one of the Company's joint venture partnerships due to a challenging business climate in its market.

The decrease in income in 2013 compared to 2012 is primarily the result of a $2.9 increase recorded in 2012 due to the liquidation of one of its joint ventures and a decline in profitability of one of the Company's joint venture partnerships due to a challenging business climate in its market.

Other, net represents the Company's gain on the sale of its investment in an equity security, partially offset by the impairment of other investments.

<table><tr><td rowspan="2"></td><td colspan="4">Years Ended December 31,</td></tr><tr><td>2014</td><td>2013</td><td>2012</td><td></td></tr><tr><td>Income tax expense</td><td>$ 314.1</td><td>$ 340.2</td><td>$ 359.4</td><td></td></tr><tr><td>Income tax expense as a % of income before tax</td><td>38.0%</td><td>37.2%</td><td>38.1%</td><td></td></tr></table>

The effective rate for 2014 was unfavorably impacted by the recording of a full valuation allowance for the write-down of two of the Company's investments.

The effective rate for 2013 was favorably impacted by the release of a capital loss valuation allowance and recording two years of a research and development tax credit. The American Taxpayer Relief Act of 2012 was enacted in early 2013 and reinstated the R&D tax credit for 2012 and extended the credit for calendar year 2013.

The effective tax rate for 2012 was favorably impacted by a decrease in the reserve for unrecognized income tax benefits, partially offset by an increase in tax on the additional investment in the Company's Canadian subsidiary.

## Liquidity, Capital Resources and Financial Position

The Company's strong cash-generating capability and financial condition typically have provided ready access to capital markets. The Company's principal source of liquidity is operating cash flow, supplemented by proceeds from debt offerings. This cash-generating capability is one of the Company's fundamental strengths and provides substantial financial flexibility in meeting operating, investing and financing needs.

On February 19, 2015, the Company completed its acquisition of Covance for approximately $6,200.0, pursuant to a definitive merger agreement entered into on November 2, 2014 (the “Merger Agreement”). Covance stockholders received $75.76 in cash and 0.2686 shares of the Company's common stock for each share of Covance common stock they owned immediately prior to consummation of the acquisition.

On January 30, 2015, the Company issued $2,900.0 in debt securities, consisting of $500.0 aggregate principal amount of 2.625% Senior Notes due 2020, $500.0 aggregate principal amount of 3.20% Senior Notes due 2022, $1,000.0 aggregate principal amount of 3.60% Senior Notes due 2025 and $900.0 aggregate principal amount of 4.700% Senior Notes due 2045 (together, the "Acquisition Notes"). Net proceeds from the offering of the Acquisition Notes were $2,870.2 after deducting underwriting discounts and other estimated expenses of the offering. Net proceeds were used to pay a portion of the cash consideration and the fees and expenses in connection with the Covance acquisition.

With the acquisition of Covance, the Company anticipates a significant increase in the total debt to consolidated EBITDA ratio for the combined company. The Company expects to maintain an investment grade credit profile and intends to utilize its free cash flow to pay down debt and make small "fold-in" acquisitions.

On November 1, 2013, the Company issued $700.0 in new senior notes pursuant to an effective shelf registration on Form S-3. The senior notes consisted of $400.0 aggregate principal amount of 2.50% Senior Notes due 2018 and $300.0 aggregate principal amount of 4.00% Senior Notes due 2023. The net proceeds were first used to repay all of the outstanding borrowings under the Company’s former Revolving Credit Facility and the remainder was used for general corporate purposes.

During the third quarter of 2013, the Company entered into fixed-to-variable interest rate swap agreements for the 4.625% senior notes due 2020 with an aggregate notional amount of $600.0 and variable interest rates based on one-month LIBOR plus



2.298% to hedge against changes in the fair value of a portion of the Company's long term debt. These derivative financial instruments are accounted for as fair value hedges of the senior notes due 2020. These interest rate swaps are included in other long term assets and added to the value of the senior notes, with an aggregate fair value of $18.5 at December 31, 2014. As the specific terms and notional amounts of the derivative financial instruments match those of the fixed-rate debt being hedged, the derivative instruments are assumed to be perfectly effective hedges and accordingly, there is no impact to the Company's Consolidated Statements of Operations. There were no derivative instruments designated as accounting hedges in 2012.

On August 23, 2012, the Company issued $1,000.0 in new senior notes pursuant to an effective shelf registration statement on Form S-3. The new senior notes consisted of $500.0 aggregate principal amount of 2.20% Senior Notes due 2017 and $500.0 aggregate principal amount of 3.75% Senior Notes due 2022. The net proceeds were used to repay $625.0 of the outstanding borrowings under the Company's former Revolving Credit Facility. The remaining proceeds were used for other general corporate purposes.

On July 31, 2012, the Company completed its acquisition of MEDTOX for $236.4 in cash, excluding transaction fees. The acquisition was financed through borrowings from the Company’s Revolving Credit Facility and cash on hand.

## Operating Activities

In 2014, the Company’s operations provided $739.0 of cash, reflecting the Company’s solid business results. In 2013, the Company’s operations provided $818.7 of cash. The decrease in cash provided from operations in 2014 as compared with 2013 is primarily attributable to lower net earnings and the timing of certain working capital items. The Company continues to focus on efforts to increase cash collections from all payers and to generate ongoing improvements to the claim submission processes.

## Investing Activities

Capital expenditures were $203.5, $202.2, and $173.8 for 2014, 2013, and 2012, respectively. The increase in capital spending in 2014 was related to certain integration and cost savings initiatives started by the Company. The Company expects capital expenditures of approximately $185.0 to $205.0 in 2015. Such expenditures are expected to be funded by cash flow from operations, as well as borrowings under the Company’s former Revolving Credit Facility as needed.

The Company remains committed to growing its business through a combination of internal development initiatives, technology licensing and partnership transactions and selected business acquisitions. Excluding Covance, the Company has invested a total of $579.5 over the past three years in strategic business acquisitions, including LipoScience, Inc. and Bode Technology Group, Inc. in 2014. These acquisitions have helped strengthen the Company’s geographic presence along with expanding capabilities in the specialty testing operations. The Company believes the acquisition market remains attractive with a number of opportunities to strengthen its scientific capabilities, grow esoteric testing capabilities and increase presence in key geographic areas.

The Company has invested a total of $2.5 over the past three years in licensing new testing technologies and had $30.0 net book value of capitalized patents, licenses and technology as of December 31, 2014. While the Company continues to believe its strategy of entering into licensing and technology distribution agreements with the developers of leading-edge technologies will provide future growth in revenues, there are certain risks associated with these investments. These risks include, but are not limited to, the failure of the licensed technology to gain broad acceptance in the marketplace and/or that insurance companies, managed care organizations, or Medicare and Medicaid will not approve reimbursement for these tests at a level commensurate with the costs of running the tests. Any or all of these circumstances could result in impairment in the value of the related capitalized licensing costs.

## Financing Activities

On November 2, 2014, in connection with entering into the Merger Agreement with Covance, the Company entered into a bridge facility commitment letter. Under the bridge facility commitment letter, the lenders agreed to provide a $4,250.0 senior unsecured bridge term loan credit facility consisting of a $3,850.0 364-day unsecured debt bridge tranche and a $400.0 60-day unsecured cash bridge tranche for the purpose of financing all or a portion of the cash consideration and the fees and expenses in connection with the transactions contemplated by the Merger Agreement. The bridge facility was permitted to be drawn only in a single drawing on the closing date of the Acquisition.

On December 19, 2014, the Company entered into a five-year term loan credit facility in the principal amount of $1,000.0 for the purpose of financing a portion of the cash consideration and the fees and expenses in connection with the transactions contemplated by the Merger Agreement. Pursuant to the bridge facility commitment letter, upon the Company’s entry into the term loan credit facility, the $4,250.0 bridge facility was reduced to a $3,250.0 commitment, comprised of a $2,850.0 364-day



unsecured debt bridge tranche and a $400.0 60-day cash bridge tranche. The $1,000.0 of term loan commitments made under the term loan credit facility reduced the debt bridge tranche under the bridge facility dollar for dollar.

The term loan credit facility was advanced in full on February 19, 2015, the date of the Company’s completion of the acquisition. The term loan credit facility will mature five years after the closing date of the Acquisition and may be prepaid without penalty.

On December 19, 2014, the Company also entered into an amendment and restatement of its existing senior revolving credit facility, which was originally entered into on December 21, 2011. The senior revolving credit facility, consists of a five-year revolving facility in the principal amount of up to $1,000.0, with the option of increasing the facility by up to an additional $250.0, subject to the agreement of one or more new or existing lenders to provide such additional amounts and certain other customary conditions. The new revolving credit facility also provides for a subfacility of up to $100.0 for swing line borrowings and a subfacility of up to $125.0 for issuances of letters of credit. The new revolving credit facility is permitted to be used for general corporate purposes, including working capital, capital expenditures, funding of share repurchases and certain other payments, and acquisitions and other investments.

On January 30, 2015, the Company issued the Acquisition Notes, which represent $2,900.0 in debt securities. Net proceeds from the offering of the Acquisition Notes were $2,870.2 after deducting underwriting discounts and other estimated expenses of the offering. Net proceeds were used to pay a portion of the cash consideration and the fees and expenses in connection with the Company’s acquisition of Covance. Pursuant to the bridge facility commitment letter, upon the Company’s issuance of the Acquisition Notes the remaining $2,850.0 364-day unsecured debt bridge tranche under the senior unsecured bridge term loan credit facility was terminated.

On February 13, 2015, the Company entered into a 60-day cash bridge term loan credit facility in the principal amount of $400.0 for the purpose of financing a portion of the cash consideration and the fees and expenses in connection with the transactions contemplated by the Merger Agreement. The 60-day cash bridge term loan credit facility was entered on the terms set forth in the bridge facility commitment letter for the $400.0 60-day cash bridge tranche.

The 60-day cash bridge term loan credit facility was advanced in full on February 19, 2015, the date of the Company’s completion of the Acquisition. The 60-day cash bridge term loan credit facility will mature 60 days after the closing date of the Acquisition and may be prepaid without penalty. The 60-day cash bridge term loan credit facility is subject to mandatory prepayment upon the receipt by the Company of net cash proceeds from certain asset dispositions, debt issuances, or equity issuances.

Under the term loan credit facility and the new revolving credit facility and the 60-day cash bridge term loan credit facility, which have affirmative and negative covenants that are substantially identical, the Company is subject to negative covenants limiting subsidiary indebtedness and certain other covenants typical for investment grade-rated borrowers and the Company is required to maintain a leverage ratio that varies. Prior to the acquisition closing date, the leverage ratio was required to have been no greater than 3.75 to 1.00, calculated by excluding the $2,900.0 Acquisition Notes. From and after the acquisition closing date, the leverage ratio must be no greater than 4.75 to 1.00 with respect to the last day of each of the first four fiscal quarters ending on or after the closing date, 4.25 to 1.00 with respect to the last day of each of the fifth through eighth fiscal quarters ending after the closing date, and 3.75 to 1.00 with respect to the last day of each fiscal quarter ending thereafter. The Company was in compliance with all covenants in the term loan credit facility and the new revolving credit facility at December 31, 2014. As of December 31, 2014, the ratio of total debt to consolidated EBITDA was 2.5 to 1.0.

The term loan credit facility will accrue interest at a per annum rate equal to, at the Company’s election, either a LIBOR rate plus a margin ranging from 1.125% to 2.00%, or a base rate determined according to a prime rate or federal funds rate plus a margin ranging from 0.125% to 1.00%. Advances under the new revolving credit facility will accrue interest at a per annum rate equal to, at the Company’s election, either a LIBOR rate plus a margin ranging from 1.00 to 1.60%, or a base rate determined according to a prime rate or federal funds rate plus a margin ranging from 0.00% to 0.60%. Fees are payable on outstanding letters of credit under the new revolving credit facility at a per annum rate equal to the applicable margin for LIBOR loans, and the Company is required to pay a facility fee on the aggregate commitments under the new revolving credit facility, at a per annum rate ranging from 0.125% to 0.40%. The 60-day cash bridge term loan credit facility will accrue interest at a per annum rate equal to, at the Company’s election, either a LIBOR rate plus a margin ranging from 1.25% to 2.00%, or a base rate determined according to a prime rate or federal funds rate plus a margin ranging from 0.25% to 1.00%. In each case, the interest margin applicable to the credit facilities, and the facility fee and letter of credit fees payable under the new revolving credit facility, are based on the Company’s senior credit ratings as determined by Standard & Poor’s and Moody’s, which are currently BBB and Baa2, respectively.

There were no balances outstanding on the Company’s new Revolving Credit Facility at December 31, 2014 or on its former Revolving Credit Facility at December 31, 2013.

As of December 31, 2014, the effective interest rate on the new Revolving Credit Facility was 1.1%.



On November 1, 2013, the Company issued $700.0 in new senior notes pursuant to the Company’s effective shelf registration on Form S-3. The new senior notes consisted of $400.0 aggregate principal amount of 2.50% Senior Notes due 2018 and $300.0 aggregate principal amount of 4.00% Senior Notes due 2023. The net proceeds were used to repay all of the outstanding borrowings under the Company’s former Revolving Credit Facility and for general corporate purposes.

The Senior Notes due 2018 and Senior Notes due 2023 bear interest at the rate of 2.50% per annum and 4.00% per annum, respectively, payable semi-annually on May 1 and November of each year, commencing on May 1, 2014.

On August 23, 2012, the Company issued $1,000.0 in new senior notes pursuant to the Company's effective shelf registration statement on Form S-3. The new senior notes consisted of $500.0 aggregate principal amount of 2.20% Senior Notes due 2017 and $500.0 aggregate principal amount of 3.75% Senior Notes due 2022. The net proceeds were used to repay $625.0 of the outstanding borrowings under the Company's former Revolving Credit Facility. The remaining proceeds are available for other general corporate purposes.

The Senior Notes due 2017 and Senior Notes due 2022 bear interest at the rate of 2.20% per annum and 3.75% per annum, respectively, payable semi-annually on February 23 and August 23 of each year, commencing February 23, 2013.

During 2014, the Company purchased $269.0 of its stock representing 2.7 shares. As of December 31, 2014, the Company had remaining outstanding authorization from the Board of Directors to purchase $789.5 of Company common stock.

During 2014, the Company settled notices to convert $21.9 aggregate principal amount at maturity of its zero-coupon subordinated notes with a conversion value of $28.7. The total cash used for these settlements was $18.9 and the Company also issued 0.1 additional shares of common stock.

On September 12, 2014, the Company announced that for the period of September 12, 2014 to March 11, 2015, the zero-coupon subordinated notes will accrue contingent cash interest at a rate of no less than 0.125% of the average market price of a zero-coupon subordinated note for the five trading days ended September 9, 2014, in addition to the continued accrual of the original issue discount.

On January 2, 2015, the Company announced that its zero-coupon subordinated notes may be converted into cash and common stock at the conversion rate of 13.4108 per $1,000 principal amount at maturity of the notes, subject to the terms of the zero-coupon subordinated notes and the Indenture, dated as of October 24, 2006 between the Company and The Bank of New York Mellon, as trustee and conversion agent. In order to exercise the option to convert all or a portion of the zero-coupon subordinated notes, holders are required to validly surrender their zero-coupon subordinated notes at any time during the calendar quarter beginning January 1, 2015, through the close of business on the last business day of the calendar quarter, which is 5:00 p.m., New York City time, on Tuesday, March 31, 2015. If notices of conversion are received, the Company plans to settle the cash portion of the conversion obligation with cash on hand and/or borrowings under the new revolving credit facility.

## Credit Ratings

The Company’s debt ratings of Baa2 from Moody’s and BBB from Standard and Poor’s contribute to its ability to access capital markets.

(a) Contingent future licensing payments will be made if certain events take place, such as the launch of a specific test, the transfer of certain technology, and when specified revenue milestones are met.

(b) As announced by the Company on January 2, 2015, holders of the zero-coupon subordinated notes may choose to convert their notes during the first quarter of 2015 subject to terms as defined in the note agreement. See “Note 11 to Consolidated Financial Statements” and "Credit Ratings" above for further information regarding the Company’s zero-coupon subordinated notes.

(c) The table does not include obligations under the Company’s pension and postretirement benefit plans, which are included in "Note 16 to Consolidated Financial Statements." Benefits under the Company's postretirement medical plan are made when claims are submitted for payment, the timing of which is not practicable to estimate.

(d) The table does not include the Company’s reserves for unrecognized tax benefits. The Company had a $24.9 and $34.9 reserve for unrecognized tax benefits, including interest and penalties, at December 31, 2014 and 2013, respectively, which is included in “Note 13 to Consolidated Financial Statements.” Substantially all of these tax reserves are classified in other long-term liabilities in the Company’s Consolidated Balance Sheets at December 31, 2014 and 2013.

(e) This table does not include the $2,900.0 senior notes issued January 30, 2015.

## Off-Balance Sheet Arrangements

The Company does not have transactions or relationships with “special purpose” entities, and the Company does not have any off balance sheet financing other than normal operating leases and letters of credits.

## Other Commercial Commitments

As of December 31, 2014, the Company provided letters of credit aggregating approximately $42.5, primarily in connection with certain insurance programs. Letters of credit provided by the Company are secured by the new Company’s Revolving Credit Facility and are renewed annually, around mid-year.

On October 14, 2011, the Company issued notice to a noncontrolling interest holder in its Other segment of its intent to purchase the holder's partnership units in accordance with the terms of the joint venture's partnership agreement. On November 28, 2011, this purchase was completed for a total purchase price of CN$151.7 as outlined in the partnership agreement (CN$147.8 plus certain adjustments relating to cash distribution hold backs made to finance recent business acquisitions and capital expenditures). The purchase of these additional partnership units brings the Company's percentage interest owned to 98.2%.

The contractual value of the remaining noncontrolling interest put totals $17.7 at December 31, 2014. At December 31, 2014 and 2013, $17.7 and $19.4, respectively, have been classified as mezzanine equity in the Company's consolidated balance sheet.

Based on current and projected levels of operations, coupled with availability under its Revolving Credit Facility, the Company believes it has sufficient liquidity to meet both its anticipated short-term and long-term cash needs; however, the Company continually reassesses its liquidity position in light of market conditions and other relevant factors.

## Covance Drug Development Revenue-Generating Arrangements

The Company expects that Covance Drug Development's revenues will be generated from contractual arrangements that are similar in structure to Covance's historical experience. Historically, a majority of revenues have been earned under contracts that range in duration from a few months to two years, but can extend in duration up to five years or longer. Covance Drug Development also has committed minimum volume arrangements with certain clients with initial terms that generally range in duration from three to ten years. Underlying these arrangements are individual project contracts for the specific services to be provided. These arrangements enable Covance Drug Development's clients to secure its services in exchange for which they commit to purchase an annual minimum dollar value, or volume, of services. Under these types of arrangements, if the annual minimum volume commitment is not reached, the client is required to pay Covance Drug Development for the shortfall.

Many of Covance Drug Development's client contracts are either fixed price or fee-for-service with a cap. To a lesser extent, some of its contracts are fee-for-service without a cap. In cases where the contracts are fixed price, Covance Drug Development may bear the cost of overruns, or Covance Drug Development may benefit if the costs are lower than anticipated. In cases where contracts are fee-for-service with a cap, the contracts contain an overall budget for the trial based on time and cost estimates. If costs are lower than anticipated, the client generally keeps the savings, but if costs are higher than estimated, Covance Drug Development may be responsible for the overrun unless the increased cost is a result of a scope change or other factors outside



of its control, such as an increase in the number of patients to be enrolled or the type or amount of data to be collected. Contracts may range in duration from a few months to several years or longer depending on the nature of the work performed. In some cases, Covance Drug Development bills the client for the total contract value in progress-based installments as it reaches certain non-contingent billing milestones over the contract duration.

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

## New Accounting Pronouncements

In February 2013, the FASB issued a new accounting standard on joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date. Under this new standard, obligations resulting from joint and several liability arrangements are to be measured as the sum of: (a) the amount the reporting entity agreed with its co-obligors that it will pay and (b) any additional amount the reporting entity expects to pay on behalf of its co-obligors. This standard, which applies prospectively, became effective for the Company beginning January 1, 2014. The adoption of this standard did not have a material effect on the consolidated financial statements.

In March 2013, the FASB issued a new accounting standard on foreign currency matters that clarifies the guidance of a parent company's accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. Under this new standard, a parent company that ceases to have a controlling financial interest in a foreign subsidiary or group of assets within a foreign entity shall release any related cumulative translation adjustment into net income only if a sale or transfer results in complete or substantially complete liquidation of the foreign entity. This standard, which applies prospectively, became effective for the Company beginning January 1, 2014. The adoption of this standard did not have a material effect on the consolidated financial statements.

In April 2014, the FASB issued a new accounting standard on discontinued operations that significantly changes criteria for discontinued operations and disclosures for disposals. Under this new standard, to be a discontinued operation, a component or group of components must represent a strategic shift that has (or will have) a major effect on an entity's operations and financial results. Expanded disclosures for discontinued operations include more details about earnings and balance sheet accounts, total operating and investing cash flows, and cash flows resulting from continuing involvement. The guidance is to be applied prospectively to all new disposals of components and new classifications as held for sale beginning in 2015, with early adoption allowed in 2014. The adoption of this standard is not expected to have a material impact on the consolidated financial statements.

In May 2014, the FASB issued the converged standard on revenue recognition with the objective of providing a single, comprehensive model for all contracts with customers to improve comparability in the financial statements of companies reporting using International Financial Reporting Standards and U.S. Generally Accepted Accounting Principles. The standard contains principles that an entity must apply to determine the measurement of revenue and timing of when it is recognized. The underlying principle is that an entity must recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. An entity can apply the revenue standard retrospectively to each prior reporting period presented (full retrospective method) or retrospectively with the cumulative effect of initially applying the standard recognized at the date of initial application in retained earnings. The revenue standard is effective for the Company beginning January 1, 2017. The Company is currently evaluating the expected impact of the standard.

In August 2014, the FASB issued a new accounting standard that explicitly requires management to assess an entity's ability to continue as a going concern, and to provide related financial statement footnote disclosures in certain circumstances. Under this standard, in connection with each annual and interim period, management must assess whether there is substantial doubt about an entity's ability to continue as a going concern within one year after the financial statements are issued (or available to be issued when applicable). Management shall consider relevant conditions and events that are known and reasonably knowable at such issuance date. Substantial doubt about an entity's ability to continue as a going concern exists if it is probable that the entity will be unable to meet its obligations as they become due within one year after issuance date. Disclosures will be required if conditions or events give rise to substantial doubt. This standard is effective for the Company for the annual period after December 15, 2016, with early adoption permitted. The adoption of this standard is not expected to have a material impact on the consolidated financial statements.



## Critical Accounting Policies

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported periods. While the Company believes these estimates are reasonable and consistent, they are by their very nature, estimates of amounts that will depend on future events. Accordingly, actual results could differ from these estimates. The Company’s Audit Committee periodically reviews the Company’s significant accounting policies. The Company’s critical accounting policies arise in conjunction with the following:

• Revenue recognition and allowance for doubtful accounts;

• Pension expense;

• Accruals for self insurance reserves;

• Income taxes; and

• Goodwill and indefinite-lived assets

## Revenue recognition and allowance for doubtful accounts

Revenue is recognized for services rendered when the testing process is complete and test results are reported to the ordering physician. The Company’s sales are generally billed to three types of payers – clients, patients and third parties such as managed care companies, Medicare and Medicaid. For clients, sales are recorded on a fee-for-service basis at the Company’s client list price, less any negotiated discount. Patient sales are recorded at the Company’s patient fee schedule, net of any discounts negotiated with physicians on behalf of their patients, or fees made available through charity care or an uninsured patient program. The Company bills third-party payers in two ways – fee-for-service and capitated agreements. Fee-for-service third-party payers are billed at the Company’s patient fee schedule amount, and third-party revenue is recorded net of contractual discounts. These discounts are recorded at the transaction level at the time of sale based on a fee schedule that is maintained for each third-party payer. The majority of the Company’s third-party sales are recorded using an actual or contracted fee schedule at the time of sale. For the remaining third-party sales, estimated fee schedules are maintained for each payer. Adjustments to the estimated payment amounts are recorded at the time of final collection and settlement of each transaction as an adjustment to revenue. These adjustments are not material to the Company’s results of operations in any period presented. The Company periodically adjusts these estimated fee schedules based upon historical payment trends. Under capitated agreements with managed care companies, the Company recognizes revenue based on a negotiated monthly contractual rate for each member of the managed care plan regardless of the number or cost of services performed.

The Company has a formal process to estimate and review the collectibility of its receivables based on the period of time they have been outstanding. Bad debt expense is recorded within selling, general and administrative expenses as a percentage of sales considered necessary to maintain the allowance for doubtful accounts at an appropriate level. The Company’s process for determining the appropriate level of the allowance for doubtful accounts involves judgment, and considers such factors as the age of the underlying receivables, historical and projected collection experience, and other external factors that could affect the collectibility of its receivables. Accounts are written off against the allowance for doubtful accounts based on the Company’s write-off policy (e.g., when they are deemed to be uncollectible). In the determination of the appropriate level of the allowance, accounts are progressively reserved based on the historical timing of cash collections relative to their respective aging categories within the Company’s receivables. These collection and reserve processes, along with the close monitoring of the billing process, help reduce the risks of material revisions to reserve estimates resulting from adverse changes in collection or reimbursement experience.



The following table presents the percentage of the Company’s net accounts receivable outstanding by aging category at December 31, 2014 and 2013:

<table><tr><td>Days Outstanding</td><td>2014</td><td>2013</td></tr><tr><td>0 - 30</td><td>48.4%</td><td>46.4%</td></tr><tr><td>31 - 60</td><td>18.6%</td><td>19.3%</td></tr><tr><td>61 - 90</td><td>11.9%</td><td>11.5%</td></tr><tr><td>91 - 120</td><td>7.1%</td><td>7.1%</td></tr><tr><td>121 - 150</td><td>3.8%</td><td>3.4%</td></tr><tr><td>151 - 180</td><td>3.6%</td><td>3.8%</td></tr><tr><td>181 - 270</td><td>5.7%</td><td>7.3%</td></tr><tr><td>271 - 360</td><td>0.7%</td><td>0.9%</td></tr><tr><td>Over 360</td><td>0.1%</td><td>0.3%</td></tr></table>

The above table excludes the percentage of net accounts receivable outstanding by aging category for the Other segment, and its other smaller foreign operations. Combined, these foreign net accounts receivable balances comprise less than 6.0% of the Company's total net accounts receivable balances. The Company believes that including the aging of the accounts receivable for these foreign operations would not be representative of the majority of the accounts receivable by aging category for the Company. The majority of the foreign accounts receivable are due from the provincial government and are generally paid within 30-60 days of billing.

## Pension Expense

The Company has a defined benefit retirement plan (the "Company Plan") and a non-qualified supplemental retirement plan (the "PEP"). In October 2009, the Company received approval from its Board of Directors to freeze any additional service-based credits for any years of service after December 31, 2009 on the Company Plan and the PEP. Both plans have been closed to new participants. Employees participating in the Company Plan and the PEP no longer earn service-based credits, but continue to earn interest credits. In addition, effective January 1, 2010, all employees eligible for the defined contribution retirement plan (the "401K Plan") receive a minimum 3% non-elective contribution ("NEC") concurrent with each payroll period. The 401K Plan also permits discretionary contributions by the Company of up to 1% and up to 3% of pay for eligible employees, based on service.

The Company Plan covers substantially all employees hired prior to December 31, 2009. The benefits to be paid under the Company Plan are based on years of credited service through December 31, 2009, interest credits and average compensation. The Company's policy is to fund the Company Plan with at least the minimum amount required by applicable regulations. The PEP covers the Company's senior management group. Prior to 2010, the PEP provided for the payment of the difference, if any, between the amount of any maximum limitation on annual benefit payments under the Employee Retirement Income Security Act of 1974 and the annual benefit that would be payable under the Company Plan but for such limitation. Effective January 1, 2010, employees participating in the PEP no longer earn service-based credits. The PEP is an unfunded plan.

The Company's net pension cost is developed from actuarial valuations. Inherent in these valuations are key assumptions, including discount rates and expected return on plan assets, which are updated on an annual basis at the beginning of each year. The Company is required to consider current market conditions, including changes in interest rates, in making these assumptions. Changes in pension costs may occur in the future due to changes in these assumptions. The key assumptions used in accounting for the defined benefit retirement plans were a 4.0% discount rate and a 7.0% expected long-term rate of return on plan assets as of December 31, 2014.

## Discount Rate

The Company evaluates several approaches toward setting the discount rate assumption that is used to value the benefit obligations of its retirement plans. At year-end, priority was given to use of the Towers Watson Bond:Link model, which simulates the purchase of investment-grade corporate bonds at current market yields with principal amounts and maturity dates closely matching the Company's projected cash disbursements from its plans. This completed model represents the yields to maturity that the Company could theoretically settle its plan obligations at year end. The weighted-average yield on the modeled bond portfolio is then used to form the discount rate assumption used for each retirement plan. A one percentage point decrease or increase in the discount rate would have resulted in a respective increase or decrease in 2014 retirement plan expense of $2.3.



In establishing its expected return on plan assets assumption, the Company reviews its asset allocation and develops return assumptions based on different asset classes adjusting for plan operating expenses. Actual asset over/under performance compared to expected returns will respectively decrease/increase unrecognized loss. The change in the unrecognized loss will change amortization cost in upcoming periods. A one percentage point increase or decrease in the expected return on plan assets would have resulted in a corresponding change in 2014 pension expense of $2.6.

Net pension cost for 2014 was $8.1 as compared with $11.0 in 2013 and $12.1 in 2012. The decrease in pension expense was due to decreases in the amount of net amortization and deferral. The decrease in pension expense in 2013 was due to decreases in pension expense was due to decreases in the amount of net amortization and deferral as a result of higher discount rates. Projected pension expense for the Company Plan and the PEP is expected to increase to $11.6 in 2015 as a result of a lower assumed discount rate and changes in participant mortality tables.

Further information on the Company’s defined benefit retirement plan is provided in Note 16 to the consolidated financial statements.

## Accruals for Self-insurance Reserves

Accruals for self-insurance reserves (including workers' compensation, auto and employee medical) are determined based on a number of assumptions and factors, including historical payment trends and claims history, actuarial assumptions and current and estimated future economic conditions. These estimated liabilities are not discounted.

The Company is self-insured (up to certain limits) for professional liability claims arising in the normal course of business, generally related to the testing and reporting of laboratory test results. The Company maintains excess insurance which limits the Company’s maximum exposure on individual claims. The Company estimates a liability that represents the ultimate exposure for aggregate losses below those limits. The liability is discounted and is based on actuarial assumptions and factors for known and incurred but not reported claims, including the frequency and payment trends of historical claims.

If actual trends differ from these estimates, the financial results could be impacted. Historical trends have not differed materially from these estimates.

## Income Taxes

The Company accounts for income taxes utilizing the asset and liability method. Under this method deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and for tax loss carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company does not recognize a tax benefit, unless the Company concludes that it is more likely than not that the benefit will be sustained on audit by the taxing authority based solely on the technical merits of the associated tax position. If the recognition threshold is met, the Company recognizes a tax benefit measured at the largest amount of the tax benefit that the Company believes is greater than 50% likely to be realized. The Company records interest and penalties in income tax expense.

## Goodwill and Indefinite-Lived Assets

The Company assesses goodwill and indefinite-lived intangibles for impairment at least annually and more frequently if triggering events occur. The timing of the Company's annual impairment testing is the end of the fiscal year. In accordance with the Financial Accounting Standards Board (“FASB”) updates to their authoritative guidance regarding goodwill and indefinite-lived intangible asset impairment testing, an entity is allowed to first assess qualitative factors as a basis for determining whether it is necessary to perform quantitative impairment testing. If an entity determines that it is not more likely than not that the estimated fair value of an asset is less than its carrying value, then no further testing is required. Otherwise, impairment testing must be performed in accordance with the original accounting standards. The updated FASB guidance also allows an entity to bypass the qualitative assessment for any reporting unit in its goodwill assessment and proceed directly to performing the first step of the two-step assessment. Similarly, a Company can proceed directly to a quantitative assessment in the case of impairment testing for indefinite-lived intangible assets as well. In 2014 and 2013, the Company elected to bypass the purely qualitative assessments for its goodwill and indefinite-lived intangible assets and proceed to quantitative assessments utilizing methodologies as described in the following paragraphs.



Step One of the goodwill impairment test includes the estimation of the fair value of each reporting unit as compared to the book value of the reporting unit. The Company uses a market value approach for determining fair value and utilizes a number of factors such as publicly available information regarding the market capitalization of the Company as well as operating results, business plans, and present value techniques. If Step One indicates potential impairment, the second step is performed to measure the amount of the impairment.

The Company has indefinite-lived assets consisting of acquired Canadian licenses. When a quantitative analysis is considered necessary for indefinite-lived intangible assets, the Company utilizes an income approach to determine the fair value. It then compares the carrying value of the indefinite-lived asset to its fair value. Impairment losses are recorded to the extent that the carrying value of the indefinite-lived intangible asset exceeds its fair value.

There are inherent uncertainties related to the factors described above and judgment related to the impairment assessments of goodwill and indefinite-lived intangibles. The assumptions underlying the impairment analyses may change in such a manner that impairment in value may occur in the future. Any such impairment will be recognized in the period in which it becomes known.

## Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

The Company addresses its exposure to market risks, principally the market risk associated with changes in interest rates, through a controlled program of risk management that includes, from time to time, the use of derivative financial instruments such as interest rate swap agreements. Although, as set forth below, the Company’s zero-coupon subordinated notes contain features that are considered to be embedded derivative instruments, the Company does not hold or issue derivative financial instruments



for trading purposes. The Company does not believe that its exposure to market risk is material to the Company’s financial position or results of operations.

During the third quarter of 2013, the Company entered into two fixed-to-variable interest rate swap agreements for the 4.625% senior notes due 2020 with an aggregate notional amount of $600.0 and variable interest rates based on one-month LIBOR plus 2.298% to hedge against changes in the fair value of a portion of the Company's long term debt.

The Company’s zero-coupon subordinated notes contain the following two features that are considered to be embedded derivative instruments under authoritative guidance in connection with accounting for derivative instruments and hedging activities:

1) The Company will pay contingent cash interest on the zero-coupon subordinated notes after September 11, 2006, if the average market price of the notes equals 120% or more of the sum of the issue price, accrued original issue discount and contingent additional principal, if any, for a specified measurement period.

2) Holders may surrender zero-coupon subordinated notes for conversion during any period in which the rating assigned to the zero-coupon subordinated notes by Standard & Poor’s Ratings Services is BB- or lower.

Borrowings under the Company’s revolving credit facility are subject to variable interest rates, unless fixed through interest rate swaps or other agreements.

The Company has laboratory locations throughout the United States and other countries including, Belgium, Canada, China, Japan, Singapore, the United Kingdom and the United Arab Emirates and, accordingly, the earnings and cash flows generated from these operations are subject to foreign currency exchange risk.

Based upon this evaluation, the Company’s principal executive officer and principal financial officer concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this annual report.

## Changes in Internal Control Over Financial Reporting

There was no change in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended) that occurred during the most recently completed fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

## Report of Management on Internal Control Over Financial Reporting

The Company's management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934).

The internal control over financial reporting at the Company was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. Internal control over financial reporting includes those policies and procedures that:



- pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;

- provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States of America;

- provide reasonable assurance that receipts and expenditures of the Company are being made only in accordance with authorization of management and directors of the Company; and

- provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of assets that could have a material effect on the consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.

The Company's management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2014. Management based this assessment on criteria for effective internal control over financial reporting described in "Internal Control - Integrated Framework 2013" issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). Based on this assessment, the Company's management determined that, as of December 31, 2014, the Company maintained effective internal control over financial reporting. Management reviewed the results of its assessment with the Audit Committee of the Company's Board of Directors.

PricewaterhouseCoopers LLP, an independent registered public accounting firm, who audited and reported on the consolidated financial statements of the Company included in this annual report, also audited the effectiveness of the Company’s internal control over financial reporting as of December 31, 2014 as stated in its report, which is included herein immediately preceding the Company’s audited financial statements.

To the Board of Directors and Shareholders of Laboratory Corporation of America Holdings:

In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of Laboratory Corporation of America Holdings and its subsidiaries at December 31, 2014 and 2013, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2014 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the accompanying index presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2014, based on criteria established in Internal Control—Integrated Framework 2013 issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the Report of Management on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements, on the financial statement schedule, 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.

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.

## 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

## Basis of Financial Statement Presentation

Laboratory Corporation of America Holdings and its subsidiaries (the “Company”) is the second largest independent clinical laboratory company in the U.S. based on 2014 net revenues. Through a national network of laboratories, the Company offers a broad range of clinical laboratory testing services used by the medical profession in core testing, patient diagnosis, and in the monitoring and treatment of disease. In addition, the Company has developed specialty testing operations, such as oncology testing, HIV genotyping and phenotyping, diagnostic genetics, cardiovascular disease risk assessment, HIV diagnosis and monitoring, and clinical trials.

Since its founding in 1971, the Company has grown into a network of 39 primary laboratories and over 1,750 patient service centers along with a network of branches and STAT laboratories. With over 36,000 employees, the Company processes tests on approximately 500,000 patient specimens daily and has laboratory locations throughout the United States and other countries including, Belgium, Canada, China, Japan, Singapore, the United Kingdom and the United Arab Emirates. As of December 31, 2014, the Company operated within two reportable segments based on the way the Company manages its business.

The consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries for which it exercises control. Long-term investments in affiliated companies in which the Company exercises significant influence, but which it does not control, are accounted for using the equity method. Investments in which the Company does not exercise significant influence (generally, when the Company has an investment of less than 20% and no representation on the investee's board of directors) are accounted for using the cost method. All significant inter-company transactions and accounts have been eliminated. The Company does not have any variable interest entities or special purpose entities whose financial results are not included in the consolidated financial statements.

The financial statements of the Company's foreign subsidiaries are measured using the local currency as the functional currency. Assets and liabilities are translated at exchange rates as of the balance sheet date. Revenues and expenses are translated at average monthly exchange rates prevailing during the year. Resulting translation adjustments are included in "Accumulated other comprehensive income."

## Revenue Recognition

Sales are recognized on the accrual basis at the time test results are reported, which approximates when services are provided. Services are provided to certain patients covered by various third-party payer programs including various managed care organizations, as well as the Medicare and Medicaid programs. Billings for services under third-party payer programs are included in sales net of allowances for contractual discounts and allowances for differences between the amounts billed and estimated program payment amounts. Adjustments to the estimated payment amounts based on final settlement with the programs are recorded upon settlement as an adjustment to revenue. In 2014, 2013 and 2012, approximately 15.0%, 16.0% and 17.6%, respectively, of the Company's revenues were derived directly from the Medicare and Medicaid programs. The Company has capitated agreements with certain managed care customers and recognizes related revenue based on a predetermined monthly contractual rate for each member of the managed care plan regardless of the number or cost of services provided by the Company. In 2014, 2013 and 2012, approximately 3.5%, 3.2% and 3.0%, respectively, of the Company's revenues were derived from such capitated agreements.

The Company's net sales are comprised of the following:

<table><tr><td rowspan="2">Net sales</td><td colspan="4">Years Ended December 31,</td></tr><tr><td>2014</td><td>2013</td><td>2012</td><td></td></tr><tr><td>Clinical diagnostics laboratory:</td><td></td><td></td><td></td><td></td></tr><tr><td>Core Testing</td><td>$ 3,656.6</td><td>$ 3,445.1</td><td>$ 3,246.6</td><td></td></tr><tr><td>Genomic and Esoteric Testing</td><td>2,025.6</td><td>2,020.1</td><td>2,089.8</td><td></td></tr><tr><td>Other</td><td>329.4</td><td>343.1</td><td>335.0</td><td></td></tr><tr><td>Total</td><td>$ 6,011.6</td><td>$ 5,808.3</td><td>$ 5,671.4</td><td></td></tr></table>

## Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported periods. Significant estimates include the allowances for doubtful accounts, deferred tax assets, fair values and amortization lives for intangible assets, and accruals for self-insurance reserves and pensions. The allowance for doubtful accounts is determined based on historical collections trends, the aging of accounts, current economic conditions and regulatory changes. Actual results could differ from those estimates.

## Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable.

The Company maintains cash and cash equivalents with various major financial institutions. The total cash balances on deposit that exceeded the balances insured by the F.D.I.C., were approximately $49.3 at December 31, 2014. Cash equivalents at December 31, 2014, totaled $535.0, which includes amounts invested in money market funds, time deposits, municipal, treasury and government funds.

Substantially all of the Company’s accounts receivable are with companies in the health care industry and individuals. However, concentrations of credit risk are limited due to the number of the Company’s clients as well as their dispersion across many different geographic regions.

While the Company has receivables due from federal and state governmental agencies, the Company does not believe that such receivables represent a credit risk since the related health care programs are funded by federal and state governments, and payment is primarily dependent upon submitting appropriate documentation. Accounts receivable balances (gross) from Medicare and Medicaid were $135.1 and $128.6 at December 31, 2014 and 2013, respectively.

For the Company's subsidiary operations in Ontario, Canada, the Ministry of Health determines who can establish a licensed community medical laboratory and caps the amount that each of these licensed laboratories can bill the government sponsored health care plan. The Ontario government-sponsored health care plan covers the cost of clinical laboratory testing performed by the licensed laboratories. The provincial government discounts the annual testing volumes based on certain utilization discounts and establishes an annual maximum it will pay for all community laboratory tests. The agreed-upon reimbursement rates are subject to Ministry of Health review at the end of year and can be adjusted (at the government's discretion) based upon the actual volume and mix of test work performed by the licensed providers in the province during the year. The accounts receivable balances from the Ontario government sponsored health care plan were $22.4 and $33.2 at December 31, 2014 and 2013, respectively.

The portion of the Company's accounts receivable due from patients comprises the largest portion of credit risk. At December 31, 2014 and 2013, receivables due from patients represent approximately 27.1% and 27.8% of the Company's consolidated gross accounts receivable. The Company applies assumptions and judgments including historical collection experience for assessing collectibility and determining allowances for doubtful accounts for accounts receivable from patients.

## Earnings per Share

Basic earnings per share is computed by dividing net earnings attributable to Laboratory Corporation of America Holdings by the weighted average number of common shares outstanding. Diluted earnings per share is computed by dividing net earnings including the impact of dilutive adjustments by the weighted average number of common shares outstanding plus potentially dilutive shares, as if they had been issued at the earlier of the date of issuance or the beginning of the period presented. Potentially dilutive common shares result primarily from the Company’s outstanding stock options, restricted stock awards, performance share awards, and shares issuable upon conversion of zero-coupon subordinated notes.

## Stock Compensation Plans

The Company measures stock compensation cost for all equity awards at fair value on the date of grant and recognizes compensation expense over the service period for awards expected to vest. The fair value of restricted stock units and performance share awards is determined based on the number of shares granted and the quoted price of the Company’s common stock on the grant date. Such value is recognized as expense over the service period, net of estimated forfeitures. The estimation of equity awards that will ultimately vest requires judgment and the Company considers many factors when estimating expected forfeitures, including types of awards, employee class, and historical experience. The cumulative effect on current and prior periods of a change in the estimated forfeiture rate is recognized as compensation expense in earnings in the period of the revision. Actual results and future estimates may differ substantially from the Company’s current estimates.

See Note 14 for assumptions used in calculating compensation expense for the Company’s stock compensation plans.

## Cash Equivalents

Cash and cash equivalents consist of highly liquid instruments, such as commercial paper, time deposits, and other money market instruments, which have original maturities of three months or less.

## Inventories

Inventories, consisting primarily of purchased laboratory and client supplies, are stated at the lower of cost (first-in, first-out) or market.

## Property, Plant and Equipment

Property, plant and equipment are recorded at cost. The cost of properties held under capital leases is equal to the lower of the net present value of the minimum lease payments or the fair value of the leased property at the inception of the lease. Depreciation and amortization expense is computed on all classes of assets based on their estimated useful lives, as indicated below, using the straight-line method.



# LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Dollars and shares in millions, except per share data)

<table><tr><td></td><td>Years</td></tr><tr><td>Buildings and building improvements</td><td>10 - 35</td></tr><tr><td>Machinery and equipment</td><td>3 - 10</td></tr><tr><td>Furniture and fixtures</td><td>5 - 10</td></tr><tr><td>Software</td><td>3 - 10</td></tr></table>

Leasehold improvements and assets held under capital leases are amortized over the shorter of their estimated useful lives or the term of the related leases. Expenditures for repairs and maintenance are charged to operations as incurred. Retirements, sales and other disposals of assets are recorded by removing the cost and accumulated depreciation from the related accounts with any resulting gain or loss reflected in the consolidated statements of operations.

## Capitalized Software Costs

The Company capitalizes purchased software which is ready for service and capitalizes software development costs incurred on significant projects starting from the time that the preliminary project stage is completed and the Company commits to funding a project until the project is substantially complete and the software is ready for its intended use. Capitalized costs include direct material and service costs and payroll and payroll-related costs. Research and development costs and other computer software maintenance costs related to software development are expensed as incurred. Capitalized software costs are amortized using the straight-line method over the estimated useful life of the underlying system, generally five years.

## Long-Lived Assets

The Company assesses goodwill and indefinite lived intangibles for impairment at least annually and more frequently if triggering events occur. The timing of the Company's annual impairment testing is the end of the fiscal year. In accordance with the Financial Accounting Standards Board (“FASB”) updates to their authoritative guidance regarding goodwill and indefinite-lived intangible asset impairment testing, an entity is allowed to first assess qualitative factors as a basis for determining whether it is necessary to perform quantitative impairment testing. If an entity determines that it is not more likely than not that the estimated fair value of an asset is less than its carrying value, then no further testing is required. Otherwise, impairment testing must be performed in accordance with the original accounting standards. The updated FASB guidance also allows an entity to bypass the qualitative assessment for any reporting unit in its goodwill assessment and proceed directly to performing the first step of the two-step assessment. Similarly, a Company can proceed directly to a quantitative assessment in the case of impairment testing for indefinite-lived intangible assets as well. In 2014 and 2013, the Company elected to bypass the purely qualitative assessments for its goodwill and indefinite-lived intangible assets and proceed to quantitative assessments utilizing methodologies as described in the following paragraphs.

Step One of the goodwill impairment test includes the estimation of the fair value of each reporting unit as compared to the book value of the reporting unit. The Company uses a market value approach for determining fair value and utilizes a number of factors such as publicly available information regarding the market capitalization of the Company as well as operating results, business plans, and present value techniques. If Step One indicates potential impairment, the second step is performed to measure the amount of the impairment.

The Company has indefinite-lived assets consisting of acquired Canadian licenses. When a quantitative analysis is considered necessary for indefinite-lived intangible assets, the Company utilizes an income approach to determine the fair value. It then compares the carrying value of the indefinite-lived asset to its fair value. Impairment losses are recorded to the extent that the carrying value of the indefinite-lived intangible asset exceeds its fair value.

There are inherent uncertainties related to the factors described above and judgment related to the Company's impairment assessments of goodwill and indefinite-lived intangibles. The assumptions underlying the impairment analyses may change in such a manner that impairment in value may occur in the future. Any such impairment will be recognized in the period in which it becomes known.

The Company completed an annual impairment analysis of its indefinite lived assets, including goodwill, and has found no instances of impairment as of December 31, 2014 or 2013.



# LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Dollars and shares in millions, except per share data)

Long-lived assets, other than goodwill and indefinite-lived assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. Recoverability of assets to be held and used is determined by the Company at the level for which there are identifiable cash flows by comparison of the carrying amount of the assets to future undiscounted net cash flows before interest expense and income taxes expected to be generated by the assets. Impairment, if any, is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets (based on market prices in an active market or on discounted cash flows). Assets to be disposed of are reported at the lower of the carrying amount or fair value. The Company found no instances of impairment as of December 31, 2014 or 2013.

## Intangible Assets

Intangible assets are amortized on a straight-line basis over the expected periods to be benefited, as set forth in the table below, such as legal life for patents and technology and contractual lives for non-compete agreements.

<table><tr><td></td><td>Years</td></tr><tr><td>Customer relationships</td><td>10 - 30</td></tr><tr><td>Patents, licenses and technology</td><td>3 - 15</td></tr><tr><td>Non-compete agreements</td><td>5 - 10</td></tr><tr><td>Trade names</td><td>5 - 10</td></tr></table>

## Debt Issuance Costs

The costs related to the issuance of debt are capitalized and amortized to interest expense over the terms of the related debt.

## Professional Liability

The Company is self-insured (up to certain limits) for professional liability claims arising in the normal course of business, generally related to the testing and reporting of laboratory test results. The Company estimates a liability that represents the ultimate exposure for aggregate losses below those limits. The liability is discounted and is based on actuarial assumptions and factors for known and incurred but not reported claims, including the frequency and payment trends of historical claims.

## Income Taxes

The Company accounts for income taxes utilizing the asset and liability method. Under this method deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and for tax loss carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company does not recognize a tax benefit unless the Company concludes that it is more likely than not that the benefit will be sustained on audit by the taxing authority based solely on the technical merits of the associated tax position. If the recognition threshold is met, the Company recognizes a tax benefit measured at the largest amount of the tax benefit that the Company believes is greater than 50% likely to be realized. The Company records interest and penalties in income tax expense.

## Derivative Financial Instruments

Interest rate swap agreements, which have been used by the Company from time to time in the management of interest rate exposure, are accounted for at fair value. The Company’s zero-coupon subordinated notes contain two features that are considered to be embedded derivative instruments under authoritative guidance in connection with accounting for derivative instruments and hedging activities. The Company believes these embedded derivatives had no fair value at December 31, 2014 and 2013.

See Note 18 for the Company’s objectives in using derivative instruments and the effect of derivative instruments and related hedged items on the Company’s financial position, financial performance and cash flows.



# LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Dollars and shares in millions, except per share data)

## Fair Value of Financial Instruments

Fair value measurements for financial assets and liabilities are determined based on the assumptions that a market participant would use in pricing an asset or liability. A three-tiered fair value hierarchy draws distinctions between market participant assumptions based on (i) observable inputs such as quoted prices in active markets (Level 1), (ii) inputs other than quoted prices in active markets that are observable either directly or indirectly (Level 2) and (iii) unobservable inputs that require the Company to use present value and other valuation techniques in the determination of fair value (Level 3).

## Research and Development

The Company expenses research and development costs as incurred.

## New Accounting Pronouncements

In February 2013, the FASB issued a new accounting standard on joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date. Under this new standard, obligations resulting from joint and several liability arrangements are to be measured as the sum of: (a) the amount the reporting entity agreed with its co-obligors that it will pay and (b) any additional amount the reporting entity expects to pay on behalf of its co-obligors. This standard, which applies prospectively, became effective for the Company beginning January 1, 2014. The adoption of this standard did not have a material effect on the consolidated financial statements.

In March 2013, the FASB issued a new accounting standard on foreign currency matters that clarifies the guidance of a parent company's accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. Under this new standard, a parent company that ceases to have a controlling financial interest in a foreign subsidiary or group of assets within a foreign entity shall release any related cumulative translation adjustment into net income only if a sale or transfer results in complete or substantially complete liquidation of the foreign entity. This standard, which applies prospectively, became effective for the Company beginning January 1, 2014. The adoption of this standard did not have a material effect on the consolidated financial statements.

In April 2014, the FASB issued a new accounting standard on discontinued operations that significantly changes criteria for discontinued operations and disclosures for disposals. Under this new standard, to be a discontinued operation, a component or group of components must represent a strategic shift that has (or will have) a major effect on an entity's operations and financial results. Expanded disclosures for discontinued operations include more details about earnings and balance sheet accounts, total operating and investing cash flows, and cash flows resulting from continuing involvement. The guidance is to be applied prospectively to all new disposals of components and new classifications as held for sale beginning in 2015, with early adoption allowed in 2014. The adoption of this standard is not expected to have a material impact on the consolidated financial statements.

In May 2014, the FASB issued the converged standard on revenue recognition with the objective of providing a single, comprehensive model for all contracts with customers to improve comparability in the financial statements of companies reporting using International Financial Reporting Standards and U.S. Generally Accepted Accounting Principles. The standard contains principles that an entity must apply to determine the measurement of revenue and timing of when it is recognized. The underlying principle is that an entity must recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. An entity can apply the revenue standard retrospectively to each prior reporting period presented (full retrospective method) or retrospectively with the cumulative effect of initially applying the standard recognized at the date of initial application in retained earnings. The revenue standard is effective for the Company beginning January 1, 2017. The Company is currently evaluating the expected impact of the standard.

In August 2014, the FASB issued a new accounting standard that explicitly requires management to assess an entity's ability to continue as a going concern, and to provide related financial statement footnote disclosures in certain circumstances. Under this standard, in connection with each annual and interim period, management must assess whether there is substantial doubt about an entity's ability to continue as a going concern within one year after the financial statements are issued (or available to be issued when applicable). Management shall consider relevant conditions and events that are known and reasonably knowable at such issuance date. Substantial doubt about an entity's ability to continue as a going concern exists if it is probable that the entity will be unable to meet its obligations as they become due within one year after issuance date. Disclosures will be required if conditions or events give rise to substantial doubt. This standard is effective for the Company for the annual period after December 15, 2016,

with early adoption permitted. The adoption of this standard is not expected to have a material impact on the consolidated financial statements.

## 2. BUSINESS ACQUISITIONS

On November 20, 2014, the Company completed its acquisition of LipoScience, Inc. ("LipoScience"), a provider of specialized cardiovascular diagnostic laboratory tests based on nuclear magnetic resonance (NMR) technology, for a purchase price of $5.25 per share or a transaction value of $67.9 (net of cash acquired).

The LipoScience purchase consideration has been allocated to the estimated fair market value of the net assets acquired, including approximately $27.2 in identifiable intangible assets (primarily non-tax deductible customer relationships, technology and trade names and trademarks) with weighted-average useful lives of approximately 19.5 years; $9.4 in deferred tax liabilities (relating to identifiable intangible assets); and a residual amount of non-tax deductible goodwill of approximately $17.4.

During the year ended December 31, 2014, the Company also acquired various other laboratories and related assets for approximately $91.5 in cash (net of cash acquired). These acquisitions were made primarily to extend the Company's geographic reach in important market areas and/or enhance the Company's scientific differentiation and esoteric testing capabilities. The purchase consideration for these acquisitions has been allocated to the estimated fair market value of the net assets acquired, including approximately $22.0 in identifiable intangible assets (primarily customer relationships and non-compete agreements) and a residual amount of goodwill of approximately $63.4.

On November 2, 2014, the Company entered into a definitive merger agreement (“Merger Agreement”) to acquire Covance Inc. (“Covance”), a leading drug development services company and a leader in nutritional analysis, for approximately $6,200.0 (the “Acquisition”). The transaction closed on February 19, 2015. Covance stockholders received $75.76 in cash and 0.2686 shares of the Company’s common stock for each share of Covance common stock they owned immediately prior to consummation of the acquisition. Former Covance stockholders own approximately 15.5% of the outstanding shares of the Company’s stock following consummation of the transaction.

In connection with entering into the Merger Agreement with Covance, the Company also entered into a bridge facility commitment letter on November 2, 2014. Under the bridge facility commitment letter, the lenders agreed to provide a $4,250.0 senior unsecured bridge term loan credit facility consisting of a $3,850.0 364-day unsecured debt bridge tranche and a $400.0 60-day unsecured cash bridge tranche for the purpose of financing all or a portion of the cash consideration and the fees and expenses in connection with the transactions contemplated by the Merger Agreement. The bridge facility was permitted to be drawn only in a single drawing on the closing date of the Acquisition.

On December 19, 2014, the Company entered into a five-year term loan credit facility in the principal amount of $1,000.0 for the purpose of financing a portion of the cash consideration and the fees and expenses in connection with the transactions contemplated by the Merger Agreement. Pursuant to the bridge facility commitment letter, upon the Company’s entry into the term loan credit facility, the $4,250.0 bridge facility was reduced to a $3,250.0 commitment, comprising a $2,850.0 364-day unsecured debt bridge tranche and a $400.0 60-day cash bridge tranche.

The Company’s recorded investment in the Alberta joint venture partnership at December 31, 2014 includes $41.3 of value assigned to the partnership’s Canadian license (with an indefinite life and deductible for tax) to conduct diagnostic testing services in the province. The Canadian partnership has a license to conduct diagnostic testing services in the province of Alberta. Substantially all of its revenue is received as reimbursement from the Alberta government’s health care programs. While the Canadian license guarantees the joint venture the ability to conduct diagnostic testing in Alberta, it does not guarantee that the provincial government will continue to reimburse diagnostic laboratory testing in future years at current levels. If the provincial government decides to limit or reduce its reimbursement of laboratory diagnostic services, it would have a negative impact on the profits and cash flows the Company derives from its Canadian joint venture. In December 2013, Alberta Health Services (“AHS”), the Alberta government’s health care program, issued a request for proposals for laboratory services that includes the scope of services performed by the Canadian partnership. In October 2014, AHS informed the Canadian partnership that it was not selected as the preferred proponent. In November 2014, the Canadian partnership submitted a vendor bid appeal. AHS has established a Vendor Bid Appeal Panel to hear the appeal. If the AHS contract award remains with the preferred proponent, then the Canadian partnership’s revenues would decrease substantially and the carrying value of the Company’s investment could potentially be impaired.

## Credit Facilities

On November 2, 2014, in connection with entering into the Merger Agreement with Covance, the Company entered into a bridge facility commitment letter. Under the bridge facility commitment letter, the lenders agreed to provide a $4,250.0 senior unsecured bridge term loan credit facility consisting of a $3,850.0 364-day unsecured debt bridge tranche and a $400.0 60-day unsecured cash bridge tranche for the purpose of financing all or a portion of the cash consideration and the fees and expenses in connection with the transactions contemplated by the Merger Agreement. The bridge facility was permitted to be drawn



# LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Dollars and shares in millions, except per share data)

only in a single drawing on the closing date of the Acquisition.

On December 19, 2014, the Company entered into a five-year term loan credit facility in the principal amount of $1,000.0 for the purpose of financing a portion of the cash consideration and the fees and expenses in connection with the transactions contemplated by the Merger Agreement. Pursuant to the bridge facility commitment letter, upon the Company’s entry into the term loan credit facility, the $4,250.0 bridge facility was reduced to a$3,250.0 commitment, comprising a $2,850.0 364-day unsecured debt bridge tranche and a $400.0 60-day cash bridge tranche. The$1,000.0 of term loan commitments made under the term loan credit facility reduced the debt bridge tranche under the bridge facility dollar for dollar.

The term loan credit facility was advanced in full on February 19, 2015, the date of the Company’s completion of the acquisition. The term loan credit facility will mature five years after the closing date of the Acquisition and may be prepaid without penalty.

On December 19, 2014, the Company also entered into an amendment and restatement of its existing senior revolving credit facility, which was originally entered into on December 21, 2011. The senior revolving credit facility consists of a five-year revolving facility in the principal amount of up to $1,000.0, with the option of increasing the facility by up to an additional $250.0, subject to the agreement of one or more new or existing lenders to provide such additional amounts and certain other customary conditions. The new revolving credit facility also provides for a subfacility of up to $100.0 for swing line borrowings and a subfacility of up to $125.0 for issuances of letters of credit. The new revolving credit facility is permitted to be used for general corporate purposes, including working capital, capital expenditures, funding of share repurchases and certain other payments, and acquisitions and other investments.

On January 30, 2015, the Company issued the Acquisition Notes, which represent $2,900.0 in debt securities consisting of $500.0 aggregate principal amount of 2.625% Senior Notes due 2020, $500.0 aggregate principal amount of 3.20% Senior Notes due 2022, $1,000.0 aggregate principal amount of 3.60% Senior Notes due 2025 and $900.0 aggregate principal amount of 4.70% Senior Notes due 2045. Net proceeds from the offering of the Acquisition Notes were $2,870.2 after deducting underwriting discounts and other estimated expenses of the offering. Net proceeds were used to pay a portion of the cash consideration and the fees and expenses in connection with the Covance acquisition. Pursuant to the bridge facility commitment letter, upon the Company’s issuance of the Acquisition Notes the remaining $2,850.0 364-day unsecured debt bridge tranche under the senior unsecured bridge term loan credit facility was terminated.

On February 13, 2015, the Company entered into a 60-day cash bridge term loan credit facility in the principal amount of $400.0 for the purpose of financing a portion of the cash consideration and the fees and expenses in connection with the transactions contemplated by the Merger Agreement. The 60-day cash bridge term loan credit facility was entered into on the terms set forth in the bridge facility commitment letter for the $400.0 60-day cash bridge tranche.

The 60-day cash bridge term loan credit facility was advanced in full on February 19, 2015, the date of the Company’s completion of the Acquisition. The 60-day cash bridge term loan credit facility will mature 60 days after the closing date of the Acquisition and may be prepaid without penalty. The 60-day cash bridge term loan credit facility is subject to mandatory prepayment upon the receipt by the Company of net cash proceeds from certain asset dispositions, debt issuances, or equity issuances.

Under the term loan facility and the new revolving credit facility and the 60-day cash bridge term loan credit facility, which have affirmative and negative covenants that are substantially identical, the Company is subject to negative covenants limiting subsidiary indebtedness and certain other covenants typical for investment grade-rated borrowers and the Company is required to maintain a leverage ratio that varies. Prior to the acquisition closing date, the leverage ratio was required to have been no greater than 3.75 to 1.0 calculated by excluding the $2,900.0 in total aggregate principal amount of the Company's senior notes issued for the purpose of funding the acquisition. From and after the acquisition closing date, the leverage ratio must be no greater than 4.75 to 1.0 with respect to the last day of each of the first four fiscal quarters ending on or after the closing date, 4.25 to 1.0 with respect to the last day of each of the fifth through eighth fiscal quarters ending after the closing date, and 3.75 to 1.0 with respect to the last day of each fiscal quarter ending thereafter. The Company was in compliance with all covenants in the term loan facility and the new revolving credit facility at December 31, 2014. As of December 31, 2014, the ratio of total debt to consolidated EBITDA was 2.5 to 1.0.

When advanced, the term loan credit facility will accrue interest at a per annum rate equal to, at the Company’s election, either a LIBOR rate plus a margin ranging from 1.125% to 2.00%, or a base rate determined according to a prime rate or federal



# LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Dollars and shares in millions, except per share data)

funds rate plus a margin ranging from 0.125% to 1.00%. Advances under the new revolving credit facility will accrue interest at a per annum rate equal to, at the Company’s election, either a LIBOR rate plus a margin ranging from 1.00% to 1.60%, or a base rate determined according to a prime rate or federal funds rate plus a margin ranging from 0.00% to 0.60%. Fees are payable on outstanding letters of credit under the new revolving credit facility at a per annum rate equal to the applicable margin for LIBOR loans, and the Company is required to pay a facility fee on the aggregate commitments under the new revolving credit facility, at a per annum rate ranging from 0.125% to 0.40%. The 60-day cash bridge term loan credit facility will accrue interest at a per annum rate equal to, at the Company’s election, either a LIBOR rate plus a margin ranging from 1.25% to 2.00%, or a base rate determined according to a prime rate or federal funds rate plus a margin ranging from 0.25% to 1.00%. In each case, the interest margin applicable to the credit facilities, and the facility fee and letter of credit fees payable under the new revolving credit facility, are based on the Company’s senior credit ratings as determined by Standard & Poor’s and Moody’s, which are currently BBB and Baa2, respectively.

There were no balances outstanding on the Company's new Revolving Credit Facility at December 31, 2014 or on its former revolving credit facility at December 31, 2013.

As of December 31, 2014, the effective interest rate on the new Revolving Credit Facility was 1.1%.

## Zero-Coupon Convertible Subordinated Notes

The Company had $106.9 and $128.8 aggregate principal amount at maturity of zero-coupon convertible subordinated notes (the “notes”) due 2021 outstanding at December 31, 2014 and 2013, respectively. The notes, which are subordinate to the Company’s bank debt, were sold at an issue price of $671.65 per $1,000.00 principal amount at maturity (representing a yield to maturity of 2.0% per year). Each one thousand dollar principal amount at maturity of the notes is convertible into 13.4108 shares of the Company’s common stock, subject to adjustment in certain circumstances, if one of the following conditions occurs:

1) If the sales price of the Company’s common stock for at least 20 trading days in a period of 30 consecutive trading days ending on the last trading day of the preceding quarter reaches specified thresholds (beginning at 120% and declining 0.1282% per quarter until it reaches approximately 110% for the quarter beginning July 1, 2021 of the accreted conversion price per share of common stock on the last day of the preceding quarter). The accreted conversion price per share will equal the issue price of a note plus the accrued original issue discount and any accrued contingent additional principal, divided by the number of shares of common stock issuable upon conversion of a note on that day. The conversion trigger price for the fourth quarter of 2014 was $73.97.

2) If the credit rating assigned to the notes by Standard & Poor’s Ratings Services is at or below BB-.

3) If the notes are called for redemption.

4) If specified corporate transactions have occurred (such as if the Company is party to a consolidation, merger or binding share exchange or a transfer of all or substantially all of its assets).

The Company may redeem for cash all or a portion of the notes at any time at specified redemption prices per one thousand dollar principal amount at maturity of the notes.

The Company has registered the notes and the shares of common stock issuable upon conversion of the notes with the Securities and Exchange Commission.

During 2014 and 2013, the Company settled notices to convert $21.9 and $25.5 aggregate principal amount at maturity of its zero-coupon subordinated notes with a conversion value of $28.7 and $31.8, respectively. The total cash used for these settlements was $18.9 and $21.5 and the Company also issued 0.1 and 0.1 additional shares of common stock, respectively. As a result of these conversions, in 2014 and 2013 the Company also reversed approximately $3.8 and $3.4, respectively, of deferred tax liability to reflect the tax benefit realized upon issuance of the shares.

On September 12, 2014, the Company announced that for the period of September 12, 2014 to March 11, 2015, the zero-coupon subordinated notes will accrue contingent cash interest at a rate of no less than 0.125% of the average market price of a zero-coupon subordinated note for the five trading days ended September 9, 2014, in addition to the continued accrual of the original issue discount.

A portion of the tax benefit associated with option exercises from stock plans reducing taxes currently payable are recorded through additional paid-in capital. The benefits recorded through additional paid-in capital are approximately $5.9, $10.6 and $8.4 in 2014, 2013 and 2012, respectively.

The effective tax rates on earnings before income taxes are reconciled to statutory federal income tax rates as follows:

<table><tr><td rowspan="2"></td><td colspan="3">Years Ended December 31,</td></tr><tr><td>2014</td><td>2013</td><td>2012</td></tr><tr><td>Statutory federal rate</td><td>35.0%</td><td>35.0%</td><td>35.0%</td></tr><tr><td>State and local income taxes, net of federal income tax effect</td><td>2.7</td><td>2.6</td><td>2.4</td></tr><tr><td>Other</td><td>0.3</td><td>(0.4)</td><td>0.7</td></tr><tr><td>Effective rate</td><td>38.0%</td><td>37.2%</td><td>38.1%</td></tr></table>

The effective rate for 2014 was unfavorably impacted by the recording of a full valuation allowance for the write down of two of the Company's investments.

The effective rate for 2013 was favorably impacted by the release of the capital loss valuation allowance and recording two years of the R&D tax credit. The American Taxpayer Relief Act of 2012 was enacted in early 2013 and reinstated the R&D tax credit for 2012 and extended the credit for calendar year 2013.

The effective tax rate for 2012 was favorably impacted by a decrease in the reserve for unrecognized income tax benefits, partially offset by an increase in tax as a result of the Company's increase in ownership percentage of its Ontario subsidiary.

The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities are as follows:

The valuation allowance increased from $16.5 in 2013 to $17.1 in 2014. The increase in the valuation allowance is primarily due to write downs in two investments which will generate a capital loss when realized for tax purposes. The Company does not project to generate capital gain income to offset the capital losses and therefore has recorded a valuation allowance associated with these assets.

The Company has foreign tax loss carryovers of $9.0 with a full valuation allowance. Most of the foreign losses have an indefinite carryover. The Company has federal tax loss carryovers of approximately $58.2 expiring periodically through 2031. The utilization of the tax loss carryovers is limited due to change of ownership rules. However, at this time the Company expects to fully utilize substantially all federal tax loss carryovers. In addition to the net operating losses, the Company has a foreign capital loss carryover of $1.9. The loss has an indefinite life and has a full valuation allowance.

The gross unrecognized income tax benefits were $16.7 and $25.6 at December 31, 2014 and 2013, respectively. It is anticipated that the amount of the unrecognized income tax benefits will change within the next twelve months; however, these changes are not expected to have a significant impact on the results of operations, cash flows or the financial position of the Company.

The Company recognizes interest and penalties related to unrecognized income tax benefits in income tax expense. Accrued interest and penalties related to uncertain tax positions totaled $8.2 and $9.3 as of December 31, 2014 and 2013, respectively. During the years ended December 31, 2014, 2013 and 2012, the Company recognized $2.2, $2.4 and $3.0, respectively, in interest and penalties expense, which was offset by a benefit of $3.3, $2.9 and $3.9, respectively.

The following table shows a reconciliation of the unrecognized income tax benefits from uncertain tax positions for the years ended December 31, 2014, 2013 and 2012:

As of December 31, 2014 and 2013, $16.7 and $25.6, respectively, is the approximate amount of unrecognized income tax benefits that, if recognized, would favorably affect the effective income tax rate in any future periods.

The Company has substantially concluded all U.S. federal income tax matters for years through 2011. Substantially all material state and local, and foreign income tax matters have been concluded through 2009 and 2001, respectively.

The Internal Revenue Service concluded the examination of the Company's 2010 and 2011 income tax returns during 2013. The Company has various state income tax examinations ongoing throughout the year. Canada Revenue Agency is conducting an audit of the 2009 and 2010 Canadian income tax return. The Company believes adequate provisions have been recorded related to all open tax years.

Substantially all of the profitable foreign earnings are repatriated on an annual basis and U.S. income taxes have been provided accordingly. The unremitted foreign earnings as of December 31, 2014 are approximately $29.5. If repatriated to the U.S., the incremental U.S. tax, net of any underlying foreign tax credit, would have increased the Company's overall income tax by approximately $1.9.

## 14. STOCK COMPENSATION PLANS

## Stock Incentive Plans

There are currently 10.2 shares authorized for issuance under the Laboratory Corporation of America Holdings 2012 Omnibus Incentive Plan and at December 31, 2014 there were 6.1 additional shares available for grant under the Plan. This Plan was approved by shareholders at the 2012 annual meeting.

## Stock Options

The following table summarizes grants of non-qualified options made by the Company to officers, key employees, and non-employee directors under all plans. Stock options are generally granted at an exercise price equal to or greater than the fair market price per share on the date of grant. Also, for each grant, options vest ratably over a period of 3 years on the anniversaries of the grant date, subject to their earlier expiration or termination.

Changes in options outstanding under the plans for the period indicated were as follows:

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the Company’s closing stock price on the last trading day of 2014 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on December 31, 2014. The amount of intrinsic value will change based on the fair market value of the Company’s stock.

Cash received by the Company from option exercises, the actual tax benefit realized for the tax deductions and the aggregate intrinsic value of options exercised from option exercises under all share-based payment arrangements during the years ended December 31, 2014, 2013, and 2012 were as follows:

The following table shows the weighted average grant-date fair values of options issued during the respective year and the weighted average assumptions that the Company used to develop the fair value estimates:

<table><tr><td></td><td>2014</td><td>2013</td><td>2012</td></tr><tr><td>Fair value per option</td><td>N/A</td><td>N/A</td><td>$ 13.43</td></tr><tr><td>Valuation assumptions</td><td></td><td></td><td></td></tr><tr><td>Weighted average expected life (in years)</td><td>N/A</td><td>N/A</td><td>3.4</td></tr><tr><td>Risk free interest rate</td><td>N/A</td><td>N/A</td><td>0.4%</td></tr><tr><td>Expected volatility</td><td>N/A</td><td>N/A</td><td>0.2</td></tr><tr><td>Expected dividend yield</td><td>N/A</td><td>N/A</td><td>—</td></tr></table>

The Black Scholes model incorporates assumptions to value stock-based awards. The risk-free interest rate for periods within the contractual life of the option is based on a zero-coupon U.S. government instrument over the contractual term of the equity instrument. Expected volatility of the Company’s stock is based on historical volatility of the Company’s stock. The Company uses historical data to calculate the expected life of the option. Groups of employees and non-employee directors that have similar exercise behavior with regard to option exercise timing and forfeiture rates are considered separately for valuation purposes. For 2014, 2013 and 2012, expense related to the Company’s stock option plan totaled $6.9, $14.5 and $21.5, respectively. The Company did not grant any options to employees during 2014 or 2013.

## Restricted Stock, Restricted Stock Units and Performance Shares

The Company grants restricted stock, restricted stock units and performance shares (“non-vested shares”) to officers and key employees and grants restricted stock and restricted stock units to non-employee directors. Restricted stock and restricted stock units typically vest annually in equal one third increments beginning on the first anniversary of the grant. A performance share

grant in 2012 represents a three-year award opportunity for the period 2012-2014, and if earned, vests fully (to the extent earned) in the first quarter of 2015. A performance share grant in 2013 represents a three-year award opportunity for the period of 2013-2015 and, if earned, vests fully (to the extent earned) in the first quarter of 2016. A performance share grant in 2014 represents a three-year award opportunity for the period of 2014-2016 and, if earned, vests fully (to the extent earned) in the first quarter of 2017. Performance share awards are subject to certain earnings per share, revenue, operating income, earnings before income taxes and total shareholder return targets, the achievement of which may increase or decrease the number of shares which the grantee earns and therefore receives upon vesting. Unearned restricted stock and performance share compensation is amortized to expense over the applicable vesting periods. For 2014, 2013 and 2012, total restricted stock, restricted stock unit and performance share compensation expense was $34.8, $19.3 and $14.3, respectively.

The following table shows a summary of non-vested shares for the year ended December 31, 2014:

<table><tr><td></td><td>Number of Shares</td><td>Weighted-Average Grant Date Fair Value</td></tr><tr><td>Non-vested at January 1, 2014</td><td>0.8</td><td>$ 90.70</td></tr><tr><td>Granted</td><td>0.6</td><td>91.77</td></tr><tr><td>Vested</td><td>(0.2)</td><td>90.62</td></tr><tr><td>Canceled</td><td>(0.1)</td><td>90.61</td></tr><tr><td>Non-vested at December 31, 2014</td><td>1.1</td><td>$ 91.30</td></tr></table>

As of December 31, 2014, there was $40.0 of total unrecognized compensation cost related to non-vested restricted stock, restricted stock unit and performance share-based compensation arrangements granted under the Company's stock incentive plans. That cost is expected to be recognized over a weighted average period of 1.7 years.

The Company has an employee stock purchase plan, begun in 1997 and amended in 1999, 2004, 2008 and 2012, with 6.3 shares of common stock authorized for issuance. The plan permits substantially all employees to purchase a limited number of shares of Company stock at 85% of market value. The Company issues shares to participating employees semi-annually in January and July of each year. Approximately 0.2 shares were purchased by eligible employees in 2014, 2013 and 2012, respectively. For 2014, 2013 and 2012, expense related to the Company’s employee stock purchase plan was $4.0, $3.5 and $4.9, respectively.

The Company uses the Black-Scholes model to calculate the fair value of the employee’s purchase right. The fair value of the employee’s purchase right and the assumptions used in its calculation are as follows:

<table><tr><td></td><td>2014</td><td>2013</td><td>2012</td></tr><tr><td>Fair value of the employee’s purchase right</td><td>$ 19.48</td><td>$ 17.22</td><td>$ 23.02</td></tr><tr><td>Valuation assumptions</td><td></td><td></td><td></td></tr><tr><td>Risk free interest rate</td><td>0.1%</td><td>0.1%</td><td>0.1%</td></tr><tr><td>Expected volatility</td><td>0.2</td><td>0.2</td><td>0.2</td></tr><tr><td>Expected dividend yield</td><td>—</td><td>—</td><td>—</td></tr></table>

## 15. COMMITMENTS AND CONTINGENT LIABILITIES

The Company is involved from time to time in various claims and legal actions, including arbitrations, class actions, and other litigation (including those described in more detail below), arising in the ordinary course of business. Some of these actions involve claims that are substantial in amount. These matters include, but are not limited to, intellectual property disputes, professional liability, employee-related matters, and inquiries, including subpoenas and other civil investigative demands, from governmental agencies and Medicare or Medicaid payers and managed care payers reviewing billing practices or requesting comment on allegations of billing irregularities that are brought to their attention through billing audits or third parties. The Company receives civil investigative demands or other inquiries from various governmental bodies in the ordinary course of its business. Such

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Dollars and shares in millions, except per share data)

inquiries can relate to the Company or other health care providers. The Company works cooperatively to respond to appropriate requests for information.

The Company is also named from time to time in suits brought under the qui tam provisions of the False Claims Act and comparable state laws. These suits typically allege that the Company has made false statements and/or certifications in connection with claims for payment from federal or state health care programs. The suits may remain under seal (hence, unknown to the Company) for some time while the government decides whether to intervene on behalf of the qui tam plaintiff. Such claims are an inevitable part of doing business in the health care field today.

The Company believes that it is in compliance in all material respects with all statutes, regulations and other requirements applicable to its clinical laboratory operations. The clinical laboratory testing industry is, however, subject to extensive regulation, and the courts have not interpreted many of these statutes and regulations. There can be no assurance therefore that those applicable statutes and regulations will not be interpreted or applied by a prosecutorial, regulatory or judicial authority in a manner that would adversely affect the Company. Potential sanctions for violation of these statutes and regulations include significant fines, the loss of various licenses, certificates and authorizations, and/or exclusion from participation in government programs.

Many of the current claims and legal actions against the Company are at preliminary stages, and many of these cases seek an indeterminate amount of damages. The Company records an aggregate legal reserve, which is determined using actuarial calculations based on historical loss rates and assessment of trends experienced in settlements and defense costs. In accordance with FASB Accounting Standards Codification Topic 450 “Contingencies”, the Company establishes reserves for judicial, regulatory, and arbitration matters outside the aggregate legal reserve if and when those matters present loss contingencies that are both probable and estimable and would exceed the aggregate legal reserve. When loss contingencies are not both probable and estimable, the Company does not establish separate reserves.

The Company is unable to estimate a range of reasonably probable loss for cases described in more detail below in which damages either have not been specified or, in the Company's judgment, are unsupported and/or exaggerated and (i) the proceedings are in early stages; (ii) there is uncertainty as to the outcome of pending appeals or motions; (iii) there are significant factual issues to be resolved; and/or (iv) there are novel legal issues to be presented. For these cases, however, the Company does not believe, based on currently available information, that the outcomes of these proceedings will have a material adverse effect on the Company's financial condition, though the outcomes could be material to the Company's operating results for any particular period, depending, in part, upon the operating results for such period.

On November 4, 2013, the State of Florida through the Office of the Attorney General filed an Intervention Complaint in a False Claims Act lawsuit, State of Florida ex rel. Hunter Laboratories, LLC and Chris Riedel v. Quest Diagnostics Incorporated, et al. in the Circuit Court for the Second Judicial Circuit for Leon County. The complaint, originally filed by a competitor laboratory, alleges that the Company overcharged Florida’s Medicaid program. The lawsuit seeks actual and treble damages and civil penalties for each alleged false claim, as well as recovery of costs, attorney’s fees, and legal expenses. On January 3, 2014, the Company filed a Petition for the Administrative Determination of the Invalidity of an Existing Rule against the Agency for Health Care Administration (“AHCA”). The Petition sought the invalidity of Rule 59G-5.110(2) of the Florida Administrative Code, which was relied upon by the Attorney General in its Intervention Complaint. On March 28, 2014, an Administrative Law Judge for the State of Florida Division of Administrative Hearings issued an order finding that Rule 59G-5.110(2) of the Florida Administrative Code was invalid. In the interim, the Attorney General filed a First Amended Intervention Complaint on January 30, 2014, which seeks actual and treble damages and civil penalties for alleged false claims, as well as recovery of costs, attorney’s fees, and legal expenses, for allegedly overcharging Florida’s Medicaid program. The Company’s Motion to Dismiss was denied in February 2015. The Company will vigorously defend the lawsuit.

As previously reported, the Company responded to an October 2007 subpoena from the United States Department of Health & Human Services Office of Inspector General's regional office in New York. On August 17, 2011, the Southern District of New York unsealed a False Claims Act lawsuit, United States of America ex rel. NPT Associates v. Laboratory Corporation of America Holdings, which alleges that the Company offered UnitedHealthcare kickbacks in the form of discounts in return for Medicare business. The Plaintiff's third amended complaint further alleges that the Company's billing practices violated False Claims Acts in fourteen states and the District of Columbia. The lawsuit seeks actual and treble damages and civil penalties for each alleged false claim, as well as recovery of costs, attorney's fees, and legal expenses. Neither the U.S. government nor any state government has intervened in the lawsuit. The Company will vigorously defend the lawsuit.

In addition, the Company has received four other subpoenas since 2007 related to Medicaid billing. In October 2009, the Company received a subpoena from the State of Michigan Department of Attorney General seeking documents related to its billing

The case was removed to the United States District Court for the Eastern District of Virginia. The lawsuit sought actual and treble damages and civil penalties for each alleged false claim, as well as recovery of costs, attorney's fees, and legal expenses. The government filed a notice declining to intervene in the case. The Company's Motion to Dismiss was granted in March of 2015. The Plaintiffs filed a notice of appeal. The parties resolved the lawsuit while it was pending an appeal.

In October 2011, a putative stockholder of the Company made a letter demand through his counsel for inspection of documents related to policies and procedures concerning the Company's Board of Directors' oversight and monitoring of the Company's billing and claim submission process. The letter also sought documents prepared for or by the Board regarding allegations from the California ex rel. Hunter Laboratories, LLC et al. v. Quest Diagnostics Incorporated, et al., lawsuit and documents reviewed and relied upon by the Board in connection with the settlement of that lawsuit. The Company is responding to the request pursuant to Delaware law.

Plaintiff has filed a notice of appeal. The Company will vigorously defend the lawsuit.

The Company was a defendant in two separate putative class action lawsuits, Christine Bohlander v. Laboratory Corporation of America, et al., and Jemuel Andres, et al. v. Laboratory Corporation of America Holdings, et al., related to overtime pay. After the filing of the two lawsuits on July 8, 2013, the Bohlander lawsuit was consolidated into the Andres lawsuit, and the consolidated lawsuit is now pending in the Superior Court of California for the County of Los Angeles. In the consolidated lawsuit, the Plaintiffs allege on behalf of similarly situated phlebotomists and couriers that the Company failed to pay overtime, failed to provide meal and rest breaks, and committed other violations of the California Labor Code. The complaint seeks monetary damages, civil penalties, costs, injunctive relief, and attorney's fees. The parties have reached a tentative class settlement, which is subject to Court approval. The Court will hold a hearing on the merits of the settlement terms on February 26, 2015. If the settlement is not approved by the Court, the Company will continue to vigorously defend the lawsuit.

and the State of California for duplicative lab tests. The lawsuit sought actual and treble damages and civil penalties for each alleged claim, as well as recovery of costs, attorney's fees, and legal expenses. Neither the United States government nor the State of California has intervened in the lawsuit. In January of 2015, Plaintiffs filed a First Amended Complaint, and the Company is no longer a defendant in the lawsuit.

Prior to the consummation of the Company’s acquisition of LipoScience, purported stockholders of LipoScience filed four putative class action lawsuits against LipoScience, members of the LipoScience board of directors, the Company and Bear Acquisition Corp., a wholly owned subsidiary of the Company, in the Delaware Court of Chancery and, with respect to one of the lawsuits, in the Superior Court of Wake County, North Carolina. The lawsuits alleged breach of fiduciary duty and/or other violations of state law arising out of the proposed acquisition. Each suit sought, among other things, injunctive relief enjoining the merger. On October 23, 2014, the case in North Carolina was voluntarily dismissed without prejudice by the Plaintiff. On October 29, 2014, the Delaware Court of Chancery consolidated the four actions under the caption In re LipoScience, Inc. Stockholder Litigation, Consolidated C.A. No. 10252-VCP (the “Consolidated Action”). On November 7, 2014, the Consolidated Action plaintiffs entered into a memorandum of understanding with the defendants regarding a settlement of the Consolidated Action. In connection with the settlement, the parties agreed that LipoScience would make certain additional disclosures to its stockholders. Subject to the completion of certain confirmatory discovery by counsel, entry by the parties into a stipulation of settlement and customary conditions, including court approval, the settlement will resolve all of the claims that were or could have been brought, including all claims relating to the merger.

On November 19, 2014, the Company entered into a definitive merger agreement to acquire Covance, Inc. (“Covance”) for approximately $6,200.0 in cash and Company common stock. The transaction closed on February 19, 2015. Prior to the closing of the transaction, purported stockholders of Covance filed two putative class action lawsuits, one in the Delaware Court of Chancery, and the other in Mercer County, New Jersey, against Covance, members of the Covance board of directors, the Company and Neon Merger Sub, Inc., a wholly owned subsidiary of the Company. The lawsuits alleged breach of fiduciary duty and/or other violations of state law arising out of the proposed acquisition. Each suit sought, among other things, injunctive relief enjoining the merger. On January 21, 2015, the case in New Jersey was voluntarily dismissed without prejudice by the Plaintiff. On February 9, 2015, the Plaintiffs in the Delaware case entered into a memorandum of understanding with the Defendants regarding a settlement. In connection with the settlement, the parties agreed that Covance would make additional disclosures to its stockholders. Subject to the entry by the parties into a stipulation of settlement and customary conditions, including court approval, the settlement will resolve all the claims that were or could have been brought, including all claims relating to the merger.

In December 2014, the Company received a Civil Investigative Demand issued pursuant to the federal False Claims Act from the U.S. Attorney’s Office for South Carolina, which requests information regarding remuneration and services provided by the Company to physicians who also received draw and processing/handling fees from competitor laboratories Health Diagnostic Laboratory, Inc. and Singulex, Inc. The Company is cooperating with the request.

Under the Company’s present insurance programs, coverage is obtained for catastrophic exposure as well as those risks required to be insured by law or contract. The Company is responsible for the uninsured portion of losses related primarily to general, professional and vehicle liability, certain medical costs and workers’ compensation. The self-insured retentions are on a per occurrence basis without any aggregate annual limit. Provisions for losses expected under these programs are recorded based upon the Company’s estimates of the aggregated liability of claims incurred. At December 31, 2014, the Company had provided letters of credit aggregating approximately $42.5, primarily in connection with certain insurance programs. The Company’s availability under its Revolving Credit Facility is reduced by the amount of these letters of credit.

The Company leases various facilities and equipment under non-cancelable lease arrangements. Future minimum rental commitments for leases with non-cancelable terms of one year or more at December 31, 2014 are as follows:

## 16. PENSION AND POSTRETIREMENT PLANS

## Pension Plans

The Company has a defined benefit retirement plan (the "Company Plan") and a nonqualified supplemental retirement plan (the "PEP"). Both plans have been closed to new participants since December 31, 2009. Employees participating in the Company Plan and the PEP no longer earn service-based credits, but continue to earn interest credits. In addition, effective January 1, 2010, all employees eligible for the defined contribution retirement plan (the "401K Plan") receive a minimum 3% non-elective contribution ("NEC") concurrent with each payroll period. Employees are not required to make a contribution to the 401K Plan to receive the NEC. The NEC is non-forfeitable and vests immediately. The 401K Plan also permits discretionary contributions by the Company of up to 1% and up to 3% of pay for eligible employees based on service.

The Company’s 401K Plan covers substantially all employees. Prior to 2010, Company contributions to the plan were based on a percentage of employee contributions. In 2013, 2012 and 2011, the Company made non-elective and discretionary contributions to the plan. Non-elective and discretionary contributions were $51.6, $49.4 and $49.0 in 2014, 2013 and 2012, respectively.

In addition, the Company Plan covers substantially all employees hired prior to December 31, 2009. The benefits to be paid under the Company Plan are based on years of credited service through December 31, 2009, interest credits and average compensation. The Company’s policy is to fund the Company Plan with at least the minimum amount required by applicable regulations. The Company made contributions to the Company Plan of $12.4, $8.4 and $11.3 in 2014, 2013 and 2012, respectively.

The PEP covers the Company’s senior management group. Prior to 2010, the PEP provided for the payment of the difference, if any, between the amount of any maximum limitation on annual benefit payments under the Employee Retirement Income Security Act of 1974 and the annual benefit that would be payable under the Company Plan but for such limitation. Effective January 1, 2010, employees participating in the PEP no longer earn service-based credits. The PEP is an unfunded plan.

Projected pension expense for the Company Plan and the PEP is expected to increase to $11.6 in 2015. This amount excludes any accelerated recognition of pension cost due to the total lump-sum payouts exceeding certain components of net periodic pension cost in a fiscal year. If such levels were to be met in 2015, the Company projects that it would result in additional pension expense of several million dollars. The actual amount would be determined in the fiscal quarter when the lump-sum payments cross the threshold and would be based upon the plan's funded status and actuarial assumptions in effect at that time.

The Company plans to make contributions of $11.1 to the Company Plan during 2015.

The effect on operations for both the Company Plan and the PEP are summarized as follows:

The Company also updated the mortality assumption to the RP-2014 Mortality Tables in 2014 which increased the Company's total projected obligation.

The Company maintains an investment policy for the management of the Company Plan’s assets. The objective of this policy is to build a portfolio designed to achieve a balance between investment return and asset protection by investing in indexed funds that are comprised of equities of high quality companies and in high quality fixed income securities which are broadly balanced and represent all market sectors. The target allocations for plan assets are 50% equity securities, 45% fixed income securities and 5% in other assets. Equity securities primarily include investments in large-cap, mid-cap and small-cap companies located in the U.S. and to a lesser extent international equities in developed and emerging countries. Fixed income securities primarily include U.S. Treasury securities, mortgage-backed bonds and corporate bonds of companies from diversified industries. Other assets include investments in commodities. The weighted average expected long-term rate of return for the Company Plan’s assets is as follows:

<table><tr><td></td><td>Target Allocation</td><td>Weighted Average Expected Long-Term Rate of Return</td></tr><tr><td>Equity securities</td><td>50.0%</td><td>3.5%</td></tr><tr><td>Fixed income securities</td><td>45.0%</td><td>1.2%</td></tr><tr><td>Other assets</td><td>5.0%</td><td>0.3%</td></tr></table>

## Post-retirement Medical Plan

The Company assumed obligations under a subsidiary's post-retirement medical plan. Coverage under this plan is restricted to a limited number of existing employees of the subsidiary. This plan is unfunded and the Company’s policy is to fund benefits as claims are incurred. The effect on operations of the post-retirement medical plan is shown in the following table:

<table><tr><td rowspan="2"></td><td colspan="4">Year ended December 31,</td></tr><tr><td>2014</td><td>2013</td><td>2012</td><td></td></tr><tr><td>Service cost for benefits earned</td><td>$ 0.2</td><td>$ 0.4</td><td>$ 0.4</td><td></td></tr><tr><td>Interest cost on benefit obligation</td><td>1.8</td><td>2.5</td><td>2.3</td><td></td></tr><tr><td>Net amortization and deferral</td><td>(7.9)</td><td>1.0</td><td>0.3</td><td></td></tr><tr><td>Post-retirement medical plan costs</td><td>$ (5.9)</td><td>$ 3.9</td><td>$ 3.0</td><td></td></tr></table>

Amounts included in accumulated other comprehensive earnings consist of unamortized net loss of $12.9. The accumulated other comprehensive earnings that are expected to be recognized as components of the post-retirement medical plan costs during 2015 are $9.3 related to amortization of the net gain resulting from the shift of Medicare-eligible participants to private exchanges.

A summary of the changes in the accumulated post-retirement benefit obligation follows:

<table><tr><td></td><td>2014</td><td>2013</td></tr><tr><td>Balance at January 1</td><td>$ 62.7</td><td>$ 60.7</td></tr><tr><td>Service cost for benefits earned</td><td>0.2</td><td>0.4</td></tr><tr><td>Interest cost on benefit obligation</td><td>1.8</td><td>2.5</td></tr><tr><td>Participants contributions</td><td>0.2</td><td>0.3</td></tr><tr><td>Actuarial loss</td><td>(7.2)</td><td>4.5</td></tr><tr><td>Benefits paid</td><td>(2.5)</td><td>(2.7)</td></tr><tr><td>Plan amendment</td><td>(26.3)</td><td>(3.0)</td></tr><tr><td>Balance at December 31</td><td>$ 28.9</td><td>$ 62.7</td></tr><tr><td></td><td></td><td></td></tr><tr><td>Recorded as:</td><td></td><td></td></tr><tr><td>Accrued expenses and other</td><td>$ 2.2</td><td>$ —</td></tr><tr><td>Other liabilities</td><td>26.7</td><td>62.7</td></tr><tr><td></td><td>$ 28.9</td><td>$ 62.7</td></tr></table>

The weighted-average discount rates used in the calculation of the accumulated post-retirement benefit obligation were 4.0% and 5.0% as of December 31, 2014 and 2013, respectively. The health care cost trend rate was assumed to be 7.0% of December 31, 2014 and 2013, declining gradually to 5.0% in the year 2021. The health care cost trend rate has a significant effect on the amounts reported. The impact of a percentage point change each year in the assumed health care cost trend rates would change the accumulated post-retirement benefit obligation as of December 31, 2014 by an increase of $0.5 or a decrease of $0.5. The impact

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Dollars and shares in millions, except per share data)

of a percentage point change on the aggregate of the service cost and interest cost components of the 2014 post-retirement benefit costs results in an increase of $0.3 or decrease of $0.2. The plan amendment in 2014 reflects the shift of Medicare-eligible participants to private exchanges and updating the mortality assumption to the RP-2014 Mortality Tables. The plan amendment in 2013 reflects the impact of shifting from projection scale AA to projection scale BB for both the RP-2000 Combined Healthy Mortality Table and the RP-2000 Disabled Mortality Table.

The following assumed benefit payments under the Company's post-retirement benefit plan, which reflect expected future service, as appropriate, and were used in the calculation of projected benefit obligations, are expected to be paid as follows:

<table><tr><td>2015</td><td>$</td><td>2.3</td></tr><tr><td>2016</td><td></td><td>2.3</td></tr><tr><td>2017</td><td></td><td>2.2</td></tr><tr><td>2018</td><td></td><td>2.2</td></tr><tr><td>2019</td><td></td><td>2.2</td></tr><tr><td>Years 2020-2024</td><td></td><td>10.3</td></tr></table>

## Deferred Compensation Plan

In 2001, the Board approved the Deferred Compensation Plan ("DCP") under which certain of the Company's executives, may elect to defer up to 100.0% of their annual cash incentive pay and/or up to 50.0% of their annual base salary and/or eligible commissions subject to annual limits established by the federal government. The DCP provides executives a tax efficient strategy for retirement savings and capital accumulation without significant cost to the Company. The Company makes no contributions to the DCP. Amounts deferred by a participant are credited to a bookkeeping account maintained on behalf of each participant, which is used for measurement and determination of amounts to be paid to a participant, or his or her designated beneficiary, pursuant to the terms of the DCP. The amounts accrued under this plan were $43.4 and $36.3 at December 31, 2014 and 2013, respectively. Deferred amounts are the Company's general unsecured obligations and are subject to claims by the Company's creditors. The Company's general assets may be used to fund obligations and pay DCP benefits.

# LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES

(Dollars and shares in millions, except per share data)

The noncontrolling interest put is valued at its contractually determined value, which approximate fair value. During the year ended December 31, 2014, the carrying value of the noncontrolling interest put decreased by $1.7 consisting of a $0.2 increase in the contractually determined value and a $1.9 decrease for foreign currency translation.

The Company offers certain employees the opportunity to participate in a DCP. A participant's deferrals are allocated by the participant to one or more of 16 measurement funds, which are indexed to externally managed funds. From time to time, to offset the cost of the growth in the participant's investment accounts, the Company purchases life insurance policies, with the Company named as beneficiary of the policies. Changes in the cash surrender value of the life insurance policies are based upon earnings and changes in the value of the underlying investments, which are typically invested in a similar manner to the participants' allocations. Changes in the fair value of the DCP obligation are derived using quoted prices in active markets based on the market price per unit multiplied by the number of units. The cash surrender value and the DCP obligations are classified within Level 2 because their inputs are derived principally from observable market data by correlation to the hypothetical investments.

The carrying amounts of cash and cash equivalents, accounts receivable, income taxes receivable, and accounts payable are considered to be representative of their respective fair values due to their short-term nature. The fair market value of the zero-coupon subordinated notes, based on market pricing, was approximately $155.6 and $155.5 as of December 31, 2014 and 2013, respectively. The fair market value of the senior notes, based on market pricing, was approximately $2,949.8 and $2,907.8 as of December 31, 2014 and 2013, respectively. The Company's note and debt instruments are considered level 2 instruments, as the fair market values of these instruments are determined using other observable inputs. The Company's investment in equity securities of $1.0 is considered a level 1 instrument, as the fair market value of this instrument is determined using observable inputs.

## 18. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

The Company addresses its exposure to market risks, principally the market risk associated with changes in interest rates, through a controlled program of risk management that includes, from time to time, the use of derivative financial instruments such as interest rate swap agreements (see Interest Rate Swap section below). Although the Company’s zero-coupon subordinated notes contain features that are considered to be embedded derivative instruments (see Embedded Derivative section below), the Company does not hold or issue derivative financial instruments for trading purposes. The Company does not believe that its exposure to market risk is material to the Company’s financial position or results of operations.

## Interest Rate Swap

During the third quarter of 2013, the Company entered into two fixed-to-variable interest rate swap agreements for the 4.625% senior notes due 2020 with an aggregate notional amount of $600.0 and variable interest rates based on one-month LIBOR plus 2.298% to hedge against changes in the fair value of a portion of the Company's long term debt. These derivative financial instruments are accounted for as fair value hedges of the senior notes due 2020. These interest rate swaps are included in other long term assets or liabilities, as applicable, and added to the value of the senior notes, with an aggregate fair value of $18.5 at December 31, 2014. As the specific terms and notional amounts of the derivative financial instruments match those of the fixed-rate debt being hedged, the derivative instruments are assumed to be perfectly effective hedges and accordingly, there is no impact to the Company's consolidated statements of operations. Cash flows from the interest rate swaps are including in operating activities. There were no derivative instruments designated as accounting hedges in 2012.

## Embedded Derivatives Related to the Zero-Coupon Subordinated Notes

The Company’s zero-coupon subordinated notes contain the following two features that are considered to be embedded derivative instruments under authoritative guidance in connection with accounting for derivative instruments and hedging activities:

1) The Company will pay contingent cash interest on the zero-coupon subordinated notes after September 11, 2006, if the average market price of the notes equals 120% or more of the sum of the issue price, accrued original issue discount and contingent additional principal, if any, for a specified measurement period.

2) Holders may surrender zero-coupon subordinated notes for conversion during any period in which the rating assigned to the zero-coupon subordinated notes by Standard & Poor’s Ratings Services is BB- or lower.

(Dollars and shares in millions, except per share data)

The Company believes these embedded derivatives had no fair value at December 31, 2014 and 2013. These embedded derivatives also had no impact on the consolidated statements of operations for the years ended December 31, 2014, 2013 and 2012.

## 22. SUBSEQUENT EVENTS

As described in Note 2, on February 19, 2015, the Company completed its acquisition of Covance, a leading drug development services company and a leader in nutritional analysis, for approximately $6,200.0. Covance stockholders received $75.76 in cash and 0.2686 shares of the Company's common stock for each share of Covance common stock they own. In connection with the transaction, the Company secured $4,250.0 in bridge financing. On January 30, 2015, the Company issued $2,900.0 in debt securities, consisting of $500.0 aggregate principal amount of 2.625% Senior Notes due 2020, $500.0 aggregate principal amount of 3.20% Senior Notes due 2022, $1,000.0 aggregate principal amount of 3.60% Senior Notes due 2025 and $900.0 aggregate principal amount of 4.70% Senior Notes due 2045. The net proceeds from the offering of the Notes were approximately $2,870.2 million after deducting underwriting discounts and other expenses of the offering. Net proceeds will be used to pay a portion of the cash consideration and the fees and expenses in connection with the Company's acquisition of Covance. The Company incurred $33.8 of transaction costs related to the Acquisition.

The Company will account for the Acquisition using the acquisition method, which requires the assets acquired and the liabilities assumed to be measured at fair value at the date of the Acquisition. The Company expects to recognize identifiable intangible assets, including customer lists, land use right and trade names and trademarks using the income approach through a discounted cash flow analysis with the discounted cash flow projections. The excess of the purchase price over the estimated fair value of the tangible net assets and identifiable intangible assets acquired will be recorded as goodwill. The factors contributing to the recognition of the amount of goodwill are based on several strategic and synergistic benefits that are expected to be realized from the Acquisition. These benefits include a complementary product offerings, enhanced global footprint, and attractive synergy opportunities and value creation.

For the year ended December 31, 2014, the unaudited pro forma consolidated revenues, net income, and basic and diluted earnings per share is $8,532.6, $523.7, $5.23 and $5.15, respectively, as though the Acquisition had occurred as of January 1, 2014. The unaudited pro forma results reflect certain adjustments related to past operating performance, acquisition costs and acquisition accounting adjustments, such as increased amortization expense based on the estimated fair value of assets acquired, the impact of the Company’s new financing arrangements, and the related tax effects. The pro forma results include costs directly attributable to the Acquisition which are not expected to have a continuing impact on the combined company, such as transactions costs of $68.8, post combination expense for acceleration of stock based compensation of $47.2 and change in control payments and severance arrangements of $23.7. The pro forma results do not include any anticipated synergies which may be achievable subsequent to the Acquisition nor do they include costs that the Company may incur to call Covance debt post-Acquisition. To produce the unaudited pro forma financial information, LabCorp adjusted Covance’s assets and liabilities to their estimated fair value; however, LabCorp has not completed the detailed valuation work necessary to arrive at the required estimates of the fair value of the Covance assets to be acquired and the liabilities to be assumed and the related allocation of purchase price.
