Covance Drug Development is a provider of end-to-end drug development services from early-stage research to regulatory approval and beyond. In 2016, LCD and CDD contributed 69.9% and 30.1%, respectively, of net revenues to the Company, and in 2015 contributed 72.9% and 27.1%, respectively. Each of the segments' net revenues in 2015 includes the results of the Company's acquisition of Covance Inc. on February 19, 2015. For further financial information about these segments, including information for each of the last three fiscal years regarding revenue, operating income and other important information, see Note 20 to the Consolidated Financial Statements.

## LabCorp Diagnostics Segment

LabCorp Diagnostics is an independent clinical laboratory business. It offers a comprehensive menu of frequently requested and specialty testing through an integrated network of primary and specialty laboratories across the U.S. This network is supported by a sophisticated information technology system, nimble and efficient logistics, local labs offering rapid response testing and approximately 1,750 patient service centers (PSCs) strategically located throughout the U.S. to provide convenient access to testing services. In addition to diagnostic testing, LCD also offers a range of other testing services, including forensic DNA analysis, food safety and integrity services, as well as occupational and wellness testing for employers. LabCorp Diagnostics offers an expansive test menu including more than 4,800 clinical, anatomic pathology, genetic and genomic tests.

With over 36,000 employees, LCD processes tests on approximately 500,000 patient specimens daily and has clinical laboratory locations throughout the U.S. and other countries, including Canada and the U.K. In 2016, LabCorp introduced more than 100 new assays and its scientists contributed to more than 450 peer-reviewed publication articles and presentations at scientific meetings.



## Clinical Laboratory Testing Industry

It is estimated that although laboratory services account for less than 3.0% of total U.S. healthcare spending (and less than 2.0% of Medicare expenditures), the results of those tests have a significant impact on physician medical decisions.

Laboratory tests and procedures are used generally by hospitals, physicians and commercial customers to assist in the diagnosis, monitoring and treatment of diseases and medical conditions through the examination of substances in blood, tissues and other specimens. The results of such tests can help in the evaluation of health, the detection of conditions or pathogens and the selection of appropriate therapies. 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 (i.e., tissue and other samples, including human cells). Clinical and anatomical pathology procedures are frequently ordered as part of regular healthcare 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.

The Company believes that in 2016, the U.S. clinical laboratory testing industry generated revenues of approximately $80.0 billion. 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 LCD. The clinical laboratory business is intensely competitive. The Centers for Medicare and Medicaid Services (CMS) of the Department of Health and Human Services (HHS) has estimated that in 2016 there were approximately 9,000 hospital-based laboratories, more than 122,000 physician-office laboratories and more than 6,000 independent clinical laboratories in the U.S. LCD competes with all of those laboratories.

LCD believes that physicians selecting a laboratory often consider the following factors, among others:

• Quality, timeliness and consistency in reporting test results;

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

• Contractual relationships with MCOs;

• Service capability and convenience;

• Number and type of tests performed;

• Connectivity solutions offered; and

• Pricing of the laboratory’s services.

LCD believes that consolidation in the clinical laboratory testing business will continue. In addition, LCD 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; mergers and acquisitions of complementary businesses; changes in payment models to performance and value-based reimbursement to deliver better outcomes at lower cost; and large, integrated service networks. In addition, legal restrictions on physician referrals and their ownership of laboratories, as well as increased regulation of laboratories, are expected to continue to contribute to the continuing consolidation of the industry.

Although testing for healthcare purposes and customers who provide healthcare services represents the most significant portion of the clinical laboratory industry, clinical laboratories also perform testing for other purposes and customers, including employment and occupational testing, DNA testing to determine parentage and to assist in forensic investigations, environmental testing, veterinary testing, wellness testing, toxicology testing, pain management testing and nutritional analysis and food safety testing.

## LCD Testing Operations and Productivity

LCD has a network of PSCs, phlebotomists placed at a customer location, branches, STAT laboratories, primary testing laboratories and specialty testing laboratories. Generally, a PSC is a facility maintained by LCD to serve the patients of physicians in a medical professional building or other strategic location. The PSC staff collects specimens for testing as requested by the physician. However, most patient specimens are collected by the customer's staff at their office or facility, or in some cases, by an LCD phlebotomist who has been placed in a physician office, hospital or other healthcare facility for the specific purpose of collecting specimens to be tested by LCD. These specimens are collected from PSCs and customer locations and sent principally through LCD's in-house courier system (and to a lesser extent, through independent couriers), to a branch or directly to one of LCD's laboratories for testing. A branch is a central facility that collects specimens in a region for shipment to one of LCD's laboratories for testing. A branch is also frequently used as a base for sales and distribution staff. STAT laboratories, which are often co-located with a branch or a PSC, perform critical testing for nearby customers, with results typically delivered within 2-3 hours of receipt of the specimen. Primary testing laboratories perform frequently requested testing on a large scale. Specialty testing laboratories perform one or more types of specialty and esoteric testing.



Each specimen and related request form is checked for completeness and given a unique identification number. The unique identification number assigned to each specimen associates the results to the appropriate patient. Once the necessary testing and billing information is entered into the software system, either electronically through an interface with the ordering physician or manually by a data entry operator, the tests are performed and the results are entered through an electronic data interface or manually, depending upon the tests and the type of instrumentation involved. Most of LCD's automated testing equipment is connected to its information systems. Most specimens are picked up from the customer's location by late afternoon or early evening and delivered to the testing laboratory by late evening or overnight, and test results are in most cases electronically delivered to the physician via electronic interfaces, the LabCorp Link \( ^{TM} \)  (formerly LabCorp Beacon) platform, smart printers or personal computer-based products.

LCD remains focused on improving quality and productivity while lowering costs throughout all phases of its operations, supported by LCD's technology, automation and facility rationalization initiatives. As part of an ongoing commitment to remain the most efficient and highest-value provider of laboratory services, LCD has undertaken a comprehensive business process improvement initiative, referred to as LaunchPad, to reengineer its systems and processes to create a sustainable and more efficient business model, and to improve the experience of all stakeholders. The Company is on track to deliver net savings of approximately $150.0 million between 2015 and 2017.

## LCD Testing Services

LCD offers a menu of more than 4,800 tests. Several hundred of those tests are 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, prostate-specific antigen (PSA), tests for sexually-transmitted diseases [e.g. Ct, Ng, Tv and human immunodeficiency virus (HIV)], hepatitis C (HCV) tests, Vitamin D, microbiology cultures and procedures, and alcohol and other substance-abuse tests. LCD performs this core group of tests in its major laboratories using sophisticated and computerized instruments, with most results reported within 24 hours or less.

In addition, LCD provides a comprehensive range of specialty testing services in the areas of women's health, allergy, diagnostic genetics, cardiovascular disease, infectious disease, endocrinology, oncology, coagulation, pharmacogenetics, toxicology and pain management.

LCD also performs a range of other testing services, including DNA testing to determine parentage and to assist in forensic investigations, and occupational testing and wellness testing for employers. In addition, LCD provides testing services to the food, beverage, nutraceutical, animal feed, chemical and agrochemical industries, which include nutritional analysis and equivalency, nutritional content fact labels, microbiological and chemical contaminant safety analysis, product development expertise, sensory testing, pilot manufacturing, pesticide screening and stability testing.

Through Litholink, LCD uses a programmatic approach to the comprehensive treatment of chronic diseases, including kidney disease, cardiovascular disease, metabolic bone disease and diabetes, and offers CDS reports to both physicians and patients. LCD believes these chronic disease programs represent potential significant savings to the healthcare system by increasing the detection of early-stage diseases and effectively managing chronic disease conditions.

## Development of New Tests

Advances in medicine continue to fundamentally change diagnostic testing. New tests are allowing clinical laboratories to provide unprecedented amounts of health-related information to physicians and patients. New molecular diagnostic tests that have been introduced over the past several years, including a gene-based test for HPV, HIV drug resistance assays, and molecular genetic testing for cystic fibrosis, have now become part of standard clinical practice. LCD continued its industry leadership in gene-based and esoteric testing in 2016, generating more than $2.0 billion in revenue from these testing services. As science continues to advance, LCD expects new testing technologies to emerge and, therefore, intends to continue to invest in advanced testing capabilities so that it can remain on the cutting edge of diagnostic laboratory testing. The Company has added, and expects to continue to add, new testing technologies and capabilities through a combination of internal development initiatives, technology licensing and partnership transactions, and selected business acquisitions. Through its sales force, LCD rapidly introduces new testing technologies to customers. This differentiation is important in the retention and growth of business.

In 2016, LCD continued its emphasis on scientific innovation and leadership with the introduction of significant test menu and automation enhancements. The Company launched more than 100 new tests in 2016. LCD is focused on the expansion of existing programs in molecular diagnostics as well as the introduction of new assays and assay platforms through licensing partnerships, acquisitions and internal development. The Company's commitment to the development of new diagnostics and applications for those diagnostics is evidenced by producing more than 450 peer-reviewed publications and presentations at scientific meetings, along with regular presentations in academic medical center grand rounds and seminars, in 2016. Examples of new tests and services introduced in 2016 include:

Infectious Diseases. LCD was the first commercial laboratory in the U.S. to offer both Zika RT-PCR and Zika Elisa testing for IgM. LCD had the first site in the U.S. to offer commercial testing services with Roche's new cobas \( ^{\circledR} $  8800 system. The system automates the entire molecular diagnostics testing process, from specimen preparation and nucleic acid extraction/purification through polymerase chain reaction (PCR) amplification and detection, and is the first high-throughput molecular system to be approved by the U.S. Food and Drug Administration (FDA) for moderately complex testing as defined pursuant to the Clinical Laboratory Improvement Amendments of 1988 (CLIA). LCD is initially running hepatitis C viral load testing on the system but plans to add testing for HIV and hepatitis B virus.

Cancer Tests. LCD made available a new application for the companion diagnostic associated with the use of Tarceva \( ^{®} \)  for the treatment of certain patients with non-small cell lung cancer (NSCLC). The Roche cobas \( ^{®} \)  EGFR Mutation Test v2 is the first blood-based test approved for clinical use in the U.S. to detect certain epidermal growth factor receptor (EGFR) gene mutations in NSCLC patients. LCD began to offer the Epi proColon \( ^{®} \)  test. This is the first FDA-approved DNA-based blood test for colorectal cancer.

Women’s Health. LCD acquired Sequenom, a pioneering laboratory for NIPT testing. This acquisition expanded LCD’s NIPT offering to include a robust menu of NIPT testing options, ranging from screening for the common autosomal trisomies, to detection of select microdeletions, to a genome-wide assessment of large copy number variants. These offerings provide the most comprehensive menu of noninvasive fetal aneuploidy screening.

Immunotherapeutics and Oncology. LCD began to offer the Ventana PD-L1 test for bladder cancer as a complementary diagnostic for Tecentriq (atezolizumab), adding it to several existing PD-L1 tests already available from LCD. In 2016, the Company performed thousands of PD-L1 tests through both LCD and CDD. The Company continues to play a pivotal role in the clinical trials for new treatments and diagnostics for cancer, including immunotherapies and companion and complementary diagnostic tests. In the innovative and rapidly expanding area of oncology immunotherapy, CDD doubled the number of study awards from 2015-2016.

LCD continues its collaborations with university, hospital and academic institutions, such as Duke University, Johns Hopkins University, Boston University, Columbia University, The Mount Sinai Hospital, the University of Tennessee and Yale University, to license and commercialize new diagnostic tests.



## LCD Technology-Enabled Solutions

LCD’s technology-enabled solutions include innovative decision support programs for chronic diseases, population health analytics tools, the LabCorp Link product, the LabCorp Patient product, and BeaconLBS. These industry-leading solutions are improving health and improving lives by helping to provide better care.

LCD’s proprietary CDS reports integrate patient-specific diagnostic information and evidence-based healthcare content to help physicians and patients better manage health. In addition, these decision-support programs promote physician adherence to evidence-based treatment guidelines.

LCD continues to develop new population health analytics programs that provide healthcare business intelligence tools to hospitals, physician practices, and accountable care organizations (ACOs). These tools are intended to assist customers in their compliance and reporting requirements with respect to efficient management of their productivity, quality and patient outcome metrics. LCD's robust rules engine maintains a large number of clinical quality measures that are highly customizable and support compliance with meaningful use and quality reporting requirements such as ACO standards, Joint Commission standards and the CMS Physician Quality Reporting System (PQRS). Real-time clinical alerts highlight gaps in care for patients and patient populations.

LCD’s centralized and proprietary LabCorp Link product, which focuses on physicians, is a series of assets and functionalities that enhance the customer experience and provide an end-to-end lab solution. These assets and functionalities include:

• A physician portal optimized for web and mobile devices;

• Express electronic ordering for essentially all of LCD's brands and services;

• Integrated results viewing and enhanced reports;

• Lab analytics that provide one-click trending of patient, test and population data;

• CDS tools at the point of testing and resulting;

- AccuDraw, which provides graphical, step-by-step guidance to help improve accuracy, workflow and turnaround time in the collection and processing of specimens at the point of collection; and

- Services-oriented architecture with rules-based engines, content aggregation and seamless integration with practice workflow.

LCD’s centralized and proprietary LabCorp Patient product is a series of assets and functionalities that enhance the patience experience. These assets and functionalities include:

• A patient portal optimized for web and market-leading mobile devices;

LCD’s BeaconLBS business provides a technology-enabled solution that provides point-of-care decision support through interfaces with test ordering systems to assist physicians in selecting a lab and the appropriate test for the patient at the appropriate time. Physicians, patients, healthcare delivery systems and payers are expected to benefit from this innovation, which supports the selection of labs that improve quality, supports evidence-based guidelines for patient care, and more effectively manages laboratory testing utilization trends without disrupting physician work flow. The BeaconLBS rules engine interfaces with payer policies for ordering, utilization, adjudication and payment.

In 2013, BeaconLBS signed an agreement with UnitedHealthcare \( ^{®} \)  to implement a laboratory benefit management program in Florida utilizing BeaconLBS. UnitedHealthcare launched the laboratory benefit management program with BeaconLBS in Florida on October 1, 2014. In April 2015, BeaconLBS achieved its targeted implementation for UnitedHealthcare in Florida, and LCD began recognizing revenue for providing this service. Initial results from the pilot program in Florida included improvement in physician use of Labs of Choice (a network of quality, cost-effective labs); improvement in physician test selection based on evidence-based guidelines; reduction in patient out-of-pocket costs; and a reduction in patient use of non-par laboratories. UnitedHealthcare announced that it will expand the BeaconLBS laboratory benefit management program to Texas, and began providing physicians in Texas access to the physician decision support tool on January 1, 2017. UnitedHealthCare delayed the program's claims impact to make further refinements to the program based on data, experience, and feedback from Texas providers. UnitedHealthcare communicated that they would notify providers 90 days in advance of initiating denials for impacted claims.

## Billing for Laboratory Services

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 arrangements with third-party administrators may further complicate the billing process. 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. A growing portion of revenue is derived from patients in the form of deductibles, coinsurance, copayments, and charges for non-covered tests.

LCD utilizes a centralized billing system in the collection of approximately 92.2% of its domestic revenue (87.4% of consolidated LCD revenue). This system generates bills to LCD customers based on payer type. Customer billing is typically generated monthly, whereas patient and third-party billing are typically generated daily. Accounts receivable are then monitored by billing personnel, 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 LCD's experience with its accounts receivable. LCD writes off accounts against the allowance for doubtful accounts when accounts receivable are deemed to be uncollectible. For customer 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 LCD's bad debt expense is related to accounts receivable from patients who are unwilling or unable to pay. In 2016, LCD continued its focus on process and account management initiatives to reduce the negative impact of bad debt expense related to patient accounts receivable.

Another component of LCD’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 test requisitions. LCD vigorously attempts to obtain any missing information or rectify any incorrect billing information received from the ordering physician. However, LCD typically performs the requested tests and returns the test results regardless of whether billing information is correct or complete. LCD believes that this experience is similar to that of its primary competitors. LCD 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 have missing billing information or have incorrect information. This is accomplished through ongoing identification of root-cause issues, deploying technology-enabled solutions, training provided to internal and external resources involved in the patient data capture process, and an emphasis on the use of electronic test ordering. Specific to technology-enabled solutions, in 2016 LCD deployed insurance eligibility verification and address validation at the time of service in all patient service centers. In 2017, the Company plans to implement technologies that enable self-service check-in for patients, and provide out-of-pocket cost estimates that include coverage limitations.

For the Company's operations in Ontario, Canada, the Ontario Ministry of Health and Long-Term Care (Ministry) determines who can establish a licensed community medical laboratory and caps the amount that each of these licensed laboratories can bill the government-sponsored healthcare plan. The Ontario government-sponsored healthcare 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 review at the end of each year and can be adjusted at the government's discretion based upon the actual volume and mix of testing services performed by the licensed healthcare providers in the province during the year. In 2016, the amount of the Company's capitated revenue derived from the Ontario government-sponsored healthcare plan was CAD $187.0 million.

## Effect of Market Changes on the Clinical Laboratory Business

The delivery of, and reimbursement for, healthcare continues to change, impacting all stakeholders, including the clinical laboratory business. Medicare (which principally serves patients who are 65 and older), Medicaid (which principally serves low-income patients) and insurers have increased their efforts to control the cost, utilization and delivery of healthcare services. Measures to regulate healthcare 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 imposing new, increasingly complex regulatory and administrative requirements. From time to time, the government also has considered changes to the Medicare and Medicaid fee schedules, and LCD believes that pressure to reduce government reimbursement will continue.

Fees for most laboratory services reimbursed by Medicare are established in the Clinical Laboratory Fee Schedule (CLFS), and fees for other testing reimbursed by Medicare, primarily related to pathology, are covered by the Physician Fee Schedule (PFS). During 2016, approximately 12.3% of LCD's revenue was reimbursed under the CLFS (12.3% in 2015), and approximately 0.8% was reimbursed under the PFS (0.9% in 2015). Over the past several years, LCD has experienced governmental reimbursement reductions as a direct result of the Patient Protection and Affordable Care Act (ACA), the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) and the Achieving a Better Life Experience Act of 2014 (ABLE Act). In addition, the Protecting Access to Medicare Act (PAMA), which became law on April 1, 2014, is expected to result in a future net reduction in reimbursement revenue under the CLFS. These laws include provisions designed to control healthcare expenses reimbursed by government programs through a combination of reductions to fee schedules, incentives to physicians to participate in alternative payment models such as risk-sharing, and new methods to establish and adjust fees.

During 2013, government payment reductions and molecular pathology payment issues (largely driven by payer policy changes)



reduced the Company’s net revenue by more than $100.0 million. The negative impact from these reimbursement challenges was largely sustained through 2016. In addition to that reduction, in 2014, LCD experienced payment reductions from the CLFS of $6.0 million and from the PFS of $6.6 million. During 2015, LCD had also experienced a 0.25% payment reduction under the CLFS, equal to approximately $2.0 million in net revenue, which was offset by an increase in reimbursement from the PFS of approximately $2.1 million. During 2016, LCD received a 0.10% payment increase under the CLFS, representing approximately $0.8 million. In 2017, LCD will receive a 1.2% payment increase under the CLFS, representing approximately $9.9 million. In 2016, LCD experienced a $2.4 million reduction to PFS net revenue driven by reductions in flow cytometry procedures. The 2016 reductions to these procedures exceeded 20%. As outlined in certain provisions of PAMA, and as interpreted by CMS, reductions in PFS rates in excess of 20% will be phased in over multiple years so as not to exceed 20% in any given year. In 2017, LCD will see continued reductions to flow cytometry procedures which carry over from the 2016 PFS change along with reductions in surgical pathology procedures. LCD estimates an aggregate $3.7 million reduction in PFS net revenue in 2017.

Under PAMA, beginning in 2018, CMS will set and make adjustments to the CLFS using market-based information that reflects the scope of private payer prices paid to laboratories that receive a majority of their Medicare revenue from the CLFS and PFS and that bill Medicare under their own National Provider Identifier (NPI). On June 23, 2016, CMS issued a final rule to implement PAMA that would require applicable laboratories, including LCD, to begin reporting their test-specific private payer payment amounts to CMS during the first quarter of 2017. CMS intends to use that private market data to calculate weighted median prices for each test (based on applicable CPT codes) that would represent the new CLFS rates beginning in 2018, subject to certain phase-in limits. For 2018-2020, a test price cannot be reduced by more than 10.0% per year; for 2021-2023, a test price cannot be reduced by more than 15.0% per year. The process of data reporting and repricing will be repeated every three years for Clinical Diagnostic Laboratory Tests (CDLTs). The second data reporting period for CDLTs will occur during the first quarter of 2020, and new CLFS rates for CDLTs will be established based on that data beginning in 2021, subject to the previously described phase-in limits for 2021-2023. The third data reporting period for CDLTs will occur during the first quarter of 2023, and new CLFS rates for CDLTs will be established based on that data beginning in 2024. CLFS rates for 2024 and subsequent periods will not be subject to phase-in limits. CLFS rates for Advanced Diagnostic Laboratory Tests (ADLTs) will be updated annually.

On November 4, 2016, CMS noted in a final rule implementing MACRA that it intends to apply Merit Based Incentive Payment System (MIPS) requirements to pathologists practicing in independent laboratories, including LCD. Under this requirement, LCD pathologists will be required to begin reporting certain quality metrics in 2017 for LCD to avoid negative PFS payment adjustments or to qualify for positive PFS payment adjustments beginning in 2019. The American Clinical Laboratory Association (ACLA) is in discussions with CMS regarding implementation of this requirement, which was not proposed in the MACRA proposed rule. LCD expects to be in compliance with any MACRA quality reporting requirements that may be implemented.

Following the 2016 U.S. general election, a single party now leads the executive branch and holds majorities in both the U.S. Senate and House of Representatives. This presents the possibility for further healthcare reform beginning in 2017, changes to, or repeal of, the ACA may continue to affect coverage, reimbursement, and utilization of laboratory services, as well as administrative requirements, in ways that are currently unpredictable. Further, structural reforms of Medicare could occur under the 115th Congress and the present administration, such as the imposition of uniform coinsurance and the combination of the Medicare Part A and Part B deductibles issued by the then existing Administration during the last 60 legislative days of the 114th Congress. On January 20, 2017, the new administration signed an executive order directing federal agencies to exercise existing authorities to reduce burdens associated with the ACA pending further action by Congress. On the same day, the White House issued a regulatory freeze memo under which rules and guidance published but not yet effective must be frozen for 60 days pending review; rules and guidance submitted for publication but not yet published must be withdrawn, and rules and guidance not yet submitted for publication must not be submitted without further direction from the Administration. Since then, further executive orders and statements from the White House and Congress have addressed potential regulatory changes that could affect the Company and its customers.

In addition, market-based changes have affected and will continue to affect the clinical laboratory business. Reimbursement from commercial payers for diagnostic testing has shifted and will continue to shift away from traditional, fee-for-service models to alternatives, including value-based, bundled pay-for-performance and other risk-sharing payment models. The growth of the managed care sector and consolidation of MCOs present various challenges and opportunities to LCD and other clinical laboratories.

In 2006, the Company signed a 10-year agreement with UnitedHealthcare to become its exclusive national laboratory in the U.S. In September 2011, the Company extended this agreement for an additional two years through the end of 2018. The Company also serves many MCOs. These organizations 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 some cases, those fee structures are specific to independent clinical laboratories, while the fees paid to hospital-based and physician-office laboratories may be different, and are typically higher. MCOs may also offer Managed Medicare or Managed Medicaid plans. In addition, some MCOs use capitation rates to fix the cost of laboratory testing services for their enrollees. Under a capitated reimbursement



arrangement, the clinical laboratory receives a per-member, per-month payment for an agreed upon menu of laboratory tests provided to MCO members during the month, regardless of the number of tests performed. For the year ended December 31, 2016, capitated contracts with MCOs accounted for approximately $225.8 million, or 3.4%, of LCD's net revenues. LCD's ability to attract and retain MCO customers has become even more important as the impact of various healthcare reform initiatives continues, including expanded health insurance exchanges and ACOs.

Despite the market changes regarding reimbursement discussed above, LCD believes that the volume of clinical laboratory testing is positively influenced by several factors, including an expansion of Medicaid, managed care, and private insurance exchanges. In addition, LCD believes that increased knowledge of the human genome and continued innovation in laboratory medicine will continue to foster greater appreciation of the value of gene-based diagnostic assays. 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 the diagnosis of disease, and the general aging of the U.S. population.

LCD believes its enhanced esoteric menu, geographic footprint and operating efficiency provide a strong platform for growth. In particular, LCD believes that it will benefit from the development of and increased interest in new companion and complementary diagnostics. Companion diagnostics are tests that must be used before a patient can be treated with a specific therapeutic, to help identify how or if the therapeutic will be effective or if it may cause adverse events. Complementary diagnostics are not required for determining who should receive the therapeutic, or how it should be used, but can give physicians information about a patient's potential response to a specific therapeutic or class of therapeutics. LCD and CDD are uniquely positioned to provide end-to-end support for the development and commercialization of companion and complementary diagnostics and their associated treatments.

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. MCOs are implementing, directly or through third parties, various type of laboratory benefit management programs, which may include lab networks, utilization management tools (such as prior authorization and/or prior notification), and claims edits, which impact coverage and reimbursement of clinical laboratory tests. Some of these programs address clinical laboratory testing broadly, while others are focused on molecular and genetic testing. In addition, continued movement by patients into consumer-driven health plans may have an impact on the utilization of laboratory testing.

## Drug Development Industry

Drug development services companies like CDD are also referred to as contract research organizations (CROs) and typically derive substantially all of their revenue from R&D as well as marketing expenditures of the biopharmaceutical industry. CDD offers comprehensive global drug development services from preclinical research through all phases of clinical development and into commercialization. Outsourcing of R&D services from biopharmaceutical companies to CROs has significantly increased in the past, and is expected to continue increasing in the future, because of several factors, including: pressures to contain costs, limitations on internal R&D capacity, the need to reduce drug development timelines, customer demand for simultaneous research in multiple countries, stringent government regulation, and therapeutic and other expertise that customers lack internally. The investment and amount of time required to develop new drugs are significant and have been increasing, and these trends create opportunities for CDD and other CROs that can help make the drug development process more efficient.

The drug development industry has many participants ranging from hundreds of small providers to a limited number of large CROs with global capabilities. CDD competes against these small and large CROs, as well as in-house departments of biopharmaceutical companies, and to a lesser extent, selected universities and teaching hospitals.

There is competition for customers on the basis of many factors, including: reputation for quality, timely performance and regulatory compliance; expertise and experience in operations, efficiency of drug development processes, technology, therapeutic areas, and market access services; scope of service offerings; strengths in various geographic markets; price; quality of facilities; ability to acquire, process, analyze and report data in a rapid and accurate manner; quality of relationships; ability to manage large-

## Leveraging the Combined Strengths of LCD and CDD

During 2016, the Company continued to expand on the combination of its diagnostic and drug development segments.

Since the completion of the acquisition of Covance in 2015 (the Acquisition), CDD has been awarded 15 studies in which the sponsor specifically indicated that the combination of LCD and CDD data was a major factor in the award. This includes studies in oncology and immuno-oncology, non-alcoholic steatohepatitis (NASH), seasonal upper respiratory infections and rare genetic disorders. LCD results data can reduce the time needed to find patients who may be suitable clinical trial subjects and physician investigators who may have a population of patients who meet clinical trial criteria. The LCD sales force can then perform outreach to those physicians to explore interest in participating in a clinical trial. In addition, through the LabCorp patient portal, the Company has established a growing database that includes more than 100,000 patients, through the end of 2016, who have consented to be contacted directly about future clinical trials.

As previously discussed, the Company has developed a leading position in the development and commercialization of companion and complementary diagnostics. CDD was the only CRO awarded a podium presentation at the 2016 World Companion Diagnostics conference.

CDD’s market access solutions have been enhanced through integration with LCD, allowing patients who require ongoing testing in connection with a treatment to receive reminders to visit a nearby LCD PSC for specimen collection or drop-off, with results seamlessly routed to their provider to support more effective and efficient monitoring.

In addition, LCD is now able to offer to hospitals and health systems the opportunity to be a research hub for participation in CDD studies and clinical trials.

## Customers

The Company provides its services to a broad range of customers.

The primary customer groups serviced by the Company include:

MCOs. The Company serves many MCOs. These organizations 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 some cases, those fee structures are specific to independent clinical laboratories, while the fees paid to hospital-based and physician-office laboratories may be different, and are typically higher. MCOs may also offer Managed Medicare or Managed Medicaid plans. In addition, some MCOs use capitation rates to fix the cost of laboratory testing services for their enrollees. Under a capitated reimbursement arrangement, the clinical laboratory receives a per-member, per-month payment for an agreed upon menu of laboratory tests provided to MCO members during the month, regardless of the number of tests performed.



Biopharmaceutical Companies. The Company serves hundreds of biopharmaceutical companies, ranging from the world’s largest biopharmaceutical companies to small and startup organizations. Contracts with these institutions generally take the form of fee-for-service or fixed-price arrangements.

Physicians and Other Healthcare Providers. Physicians who require clinical laboratory testing for their patients are a primary source of requests for LCD's testing services. Physicians may practice individually, or as part of small or large physician groups, including those operated as part of a broader health system. Fees for clinical laboratory testing services rendered for physicians are billed either to the physician, the physician group, the patient or the patient's third-party payer, such as an MCO, 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-specific 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 and Health Systems. The Company provides hospitals and health systems with services ranging from core and specialty testing to supply chain and technical support services, and the opportunity to be a research hub for participation in studies and clinical trials with CDD. Hospitals generally maintain an on-site laboratory to perform immediately needed testing for 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 that is derived from the Company’s client fee schedule. Fees for management services are typically billed monthly at contractual rates.

Other Customers. The Company serves a broad range of other customers, including managed care organizations (MCOs), governmental agencies, employers, patients and consumers, contract research organizations, food and nutritional companies and independent clinical laboratories. These customers typically pay on a negotiated fee-for-service basis or based on a set fee schedule.

## Capital Allocation

The Company believes it has a strong track record of deploying capital to investments that enhance the Company's business and returning capital to shareholders.

Since 2010, the Company has invested net cash of approximately $6.3 billion and equity of $1.8 billion in strategic business acquisitions ($2.5 billion over the same period excluding the Acquisition). These acquisitions have significantly expanded the Company’s service offerings, expanded its customer and revenue mix, as well as strengthened and broadened the scope of its geographic presence. The Company continues to evaluate acquisition opportunities that leverage the Company’s core competencies, complement existing scientific and technological capabilities, increase the Company’s presence in key geographic, therapeutic and strategic areas, and meet or exceed the Company’s financial criteria.

On February 19, 2015, the Company completed the Acquisition for $6,150.7 million. 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. Upon completion of the Acquisition, former Covance stockholders owned approximately 15.5% of the outstanding shares of the Company's stock.

From 2003 through 2015, the Company repurchased approximately $5,915.0 million in shares at an average price of approximately $69.00 per share. Following the November 2014 announcement of the Acquisition, the Company temporarily suspended its share repurchases. The Company resumed its share repurchase program in the fourth quarter of 2016, repurchasing 0.3 million shares for $43.9 million, based on settled trades as of December 31, 2016, at an average price of approximately $128.00. The Company also initiated purchases of $6.0 million, which settled directly after December 31, 2016. At the end of 2016, including unsettled purchase commitments, $739.5 million of repurchase authorization remained under the Company's share repurchase program. During 2016, the Company repaid $454.7 million of its senior notes, $150.0 million of its term loan, and $53.7 million of its zero coupon subordinated notes. In addition, the Company borrowed and repaid $139.5 million of debt through its revolving credit facility within 2016. The Company will continue to evaluate all opportunities for strategic deployment of capital in light of market conditions.

Since 2010, capital expenditures are $1.4 billion, representing approximately 3.0% of the Company’s total net revenue during the same period. The Company expects capital expenditures in 2017 to be approximately 3.0% of net revenues, primarily in connection with projects to support growth in the Company’s core businesses, projects related to LaunchPad and further Covance integration initiatives.



## Seasonality and External Factors

The Company experiences seasonality in both segments of its business. For example, testing volume generally declines during the year-end holiday period and other major holidays and can also decline due to inclement weather, reducing net revenues, operating margins and cash flows. Operations are also impacted by changes in the global economy, exchange rate fluctuations, political and regulatory changes, the progress of ongoing studies and the startup of new studies, as well as the level of expenditures made by the biopharmaceutical industry in R&D. Given the seasonality of the 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, two located in Alberta, Canada, and one located in 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 Company does not consolidate the results of these joint ventures. Effective June 30, 2015, the Company liquidated its interest in a joint venture partnership that had been located in Milwaukee, Wisconsin.

The first Canadian partnership is a leader in occupational testing across Canada similar to LCD's U.S. occupational testing services. The second 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 healthcare programs. In December 2013, Alberta Health Services (AHS), the Alberta government's healthcare program, issued a request for proposals for laboratory services that included the scope of services performed by the Canadian partnership. In October 2014, AHS informed the Canadian partnership that it had not been selected as the preferred proponent. In November 2014, the Canadian partnership submitted a vendor bid appeal upon the belief that there were significant flaws and failures in the conduct of the request for proposal process, which drove to a biased conclusion. AHS established a Vendor Bid Appeal Panel to hear the appeal, and the hearing was conducted in February 2015. In August 2015, AHS was directed to cancel the request for proposal process. Subsequently, the Canadian partnership entered into a one-year extension through March 31, 2017, of its existing contract with AHS. In August 2016, AHS and the Canadian partnership reached an agreement to extend the contract for five additional years through March 2022, with the intent to have the services provided pursuant to the contract transferred to AHS at the end of the five-year period. In consideration of AHS acquiring the assets and assuming liabilities in accordance with the parties' agreement, AHS will pay CAD $50.0 million to the partnership when the transfer is effective, subject to a working capital adjustment.

## Information Systems

The Company is committed to developing and commercializing technology-enabled solutions to support its operations and provide better care. LCD and CDD each operate standard platforms for their core business services, and the Company operates standard platforms for its financial and reporting systems. These standard systems provide consistency within workflows and information as well as a high level of system availability and stability. LCD's and CDD's primary laboratory systems, including standardized support for molecular diagnostics, digital pathology and enhanced specialty laboratory solutions, facilitate the processing of tests that generate the vast majority of LCD revenue and virtually all of CDD's central laboratory services revenue. The Company's centralized information systems are responsible for tremendous operational efficiencies, enabling the Company to achieve consistent, structured, and standardized operating results and superior patient care.



In addition, LCD and CDD each offer proprietary and industry-leading information systems, which are discussed in more detail in the sections dedicated to each of those Business Segments.

## Quality

LCD and CDD have comprehensive quality systems and processes that are appropriate for their respective businesses. This includes licensing, credentialing, training and competency of professional and technical staff, and internal auditing. In addition to the Company's own quality assurance programs, many of the Company's laboratories, facilities and processes are subject to on-site regulatory evaluations, external proficiency testing programs, and surveys, as applicable, by local or national government agencies.

Virtually all facets of the Company’s services are subject to quality assurance programs and procedures, including sensitivity, specificity and reproducibility of tests; turnaround time; customer service; data integrity; patient satisfaction; and billing. The Company’s quality assurance program includes measures that compare current performance against desired performance goals to monitor critical aspects of service to its customers and patients.

The Company has procedures for monitoring its internal performance, as well as that of its vendors, suppliers and other key stakeholders. In addition, various groups and departments within the Company, including the Company's supply chain management department, CDD's clinical trial services global vendor management department, CDD's central laboratory services expanded laboratory management services department, LCD's National Office of Quality, and project management staff supporting LCD and CDD, provide oversight to monitor and control vendor products and performance, and play an essential role in the Company's approach to quality through improvements in processes and automation.

Customer Interaction. Continual improvement in the customers’ experience with the Company is essential. Use of technology and workflow improvements within LCD’s PSCs are helping to: reduce patient wait times by expediting the patient registration process (through LabCorp Patient Appointment Scheduling), enhance the specimen collection process (through LabCorp Touch and AccuDraw) and allow patients to access their test results directly through the LabCorp Link website and mobile application. CDD processes permit faster clinical trial study start-up and subject enrollment along with timely delivery of established deliverables to enhance and improve customer interaction.

Specimen Management. The Company's standardized logistics and specimen tracking technologies allow the timely transportation, monitoring, and storage of specimens. The Company is continually working to maintain and improve its ability to timely collect, transport and track specimens from collection points to all Company or designated external locations. In 2016, CDD announced a five-year strategic alliance with Global Specimen Solutions, Inc. to provide streamlined global specimen tracking, as well as, tracking for informed consent and live data analytics that deliver actionable insights from specimens across development programs.

Quality Control. The Company regularly performs quality control testing. These may include in-process and post-process quality control checks; use of applicable control materials and reference standards, peer reviews, and data review meetings; programmed data edit checks to detect variances and unusual data patterns; dual programming; and mock runs.

LCD Internal Proficiency Testing. LCD has an extensive internal proficiency testing program to assess LCD's analytical and post-analytical phases of laboratory testing, 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 College of American Pathology (CAP) program. CAP is an independent non-governmental organization of board-certified pathologists that 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 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. A laboratory's receipt of accreditation by CAP satisfies the CMS requirement for certification. LCD's major diagnostic laboratories, CDD's major central laboratory facilities, and CDD's Phase I clinical research units in Evansville, Indiana, and Dallas, Texas, are accredited by CAP.

The Company's forensic crime laboratory, located in Lorton, Virginia, is 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 U.K. Accreditation Service (UKAS) in many areas of forensic analysis. These facilities provide crime scene investigative services,



collecting samples for DNA analysis, mitochondrial DNA testing, microscopic analysis of tool marks and paint, and other forms of forensic testing.

The Company has multiple labs that have received ISO 15189 accreditation. ISO 15189 is an international standard that recognizes the quality and technical competence of medical laboratories. The Company has 15 laboratories in the U.S. and 5 laboratories outside of the U.S. accredited with this standard, and the laboratory operated for CDD pursuant to a strategic agreement with BML, Inc. also has this accreditation. The list below reflects the Company's labs that have achieved this accreditation and the year in which it was achieved.

## 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, 2016, the Company had over 52,000 employees worldwide, approximately 23.6% of whom were employed outside of the U.S. The Company's U.S. based subsidiaries have four collective bargaining agreements, which cover approximately 700 employees. Non-U.S. based subsidiaries have 25 collective bargaining agreements, which cover approximately 1,323 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.

## Regulation and Reimbursement

## General

Because the Company operates in a number of distinct operating environments and in a variety of locations worldwide, it is subject to numerous, and sometimes overlapping, regulatory environments. Both the clinical laboratory industry and the drug development business are subject to significant governmental regulation at the national, state and local levels. As described below, these regulations concern licensure and operation of clinical laboratories, claim submission and reimbursement for laboratory



services, healthcare fraud and abuse, drug development services, security and confidentiality of health information, quality, and environmental and occupational safety.

## Regulation of Clinical Laboratories

Virtually all clinical laboratories operating in the U.S. must be certified by the federal government or by a federally approved accreditation agency. In most cases, that certification is regulated by CMS through CLIA. CLIA requires that applicable clinical laboratories meet quality assurance, quality control and personnel standards. Laboratories also must undergo proficiency testing and are subject to inspections. Clinical laboratories in locations other than the U.S. are generally subject to comparable regulation in their respective jurisdictions.

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 FDA to have a low potential for error and requiring little oversight, may apply for a certificate of waiver exempting them from most CLIA requirements. 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 laboratory requirements applicable to its laboratories operated both within the U.S. and in other countries. The Company's laboratories have continuing programs to maintain operations in compliance with 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. The FDA has issued draft guidance regarding FDA regulation of laboratory developed tests (LDTs), but if or how the draft guidance will be implemented is uncertain. On November 18, 2016, the FDA announced it would not release final guidance at this time and instead would continue to work with stakeholders, the new administration, and Congress to determine the right approach, and on January 13, 2017, the FDA released a discussion paper outlining a possible risk-based approach for FDA and CMS oversight of LDTs. There are other regulatory and legislative proposals that would increase general FDA oversight of clinical laboratories and LDTs. The outcome and ultimate impact of such proposals on the business is difficult to predict at this time.

The FDA enforces U.S. laws and regulations that govern the development, testing, manufacturing, labeling, advertising, marketing, distribution and surveillance of diagnostic products, including many of the services and products offered by the Company, and those that comprise the majority of CDD’s business. 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 noncompliance, such as fines, product suspensions, warning letters, recalls, injunctions and other civil and criminal sanctions. Other countries where the Company conducts business have similar agencies and laws with which the Company must also comply.

The operation of CDD’s preclinical laboratory facilities and clinical trial operations must conform to good laboratory practice (GLP) and good clinical practice (GCP), as applicable, as well as all other applicable standards and regulations. The preclinical and clinical studies that the Company conducts are subject to periodic inspections by the FDA as well as other drug regulatory agencies, which may include, without limitation, the Medicines and Healthcare products Regulatory Agency in the U.K. (MHRA), the European Medicines Agency, the China Food and Drug Administration, and the Pharmaceuticals and Medical Devices Agency in Japan, to determine compliance with GLP and GCP as well as other applicable standards and regulations. If the FDA determines during an inspection that the Company’s equipment, facilities, laboratories, operations, or processes do not comply with applicable FDA regulations and conditions of GLP and/or GCP, the FDA may issue a formal notice, which may be followed by a warning letter if observations are not addressed satisfactorily. Noncompliance may result in the FDA seeking civil, criminal or administrative sanctions and/or remedies against the Company, including suspension of its laboratory operations. Other countries where the Company conducts business have similar laws and regulations with which the Company must also comply.



Additionally, certain CDD services and activities, such as CMC services and manufacturing of investigational medicinal products for use in certain Phase I studies managed by CDD, must conform to current good manufacturing practice (cGMP). CDD is subject to periodic inspections by the FDA and the MHRA in order to assess, among other things, cGMP compliance. If the FDA or the MHRA identifies deficiencies during an inspection, it may issue a formal notice, which may be followed by a warning letter if observations are not addressed satisfactorily. Failure to maintain compliance with cGMP regulations and other applicable requirements of various regulatory agencies could result in fines, unanticipated compliance expenditures, suspension of manufacturing, enforcement actions, injunctions, or criminal prosecution. Other countries where the Company conducts business may have similar laws and regulations with which the Company may also be required to comply.

## The Animal Welfare Act

The conduct of animal research at CDD’s facilities in the U.S. must be in compliance with the U.S. Animal Welfare Act (AWA), which governs the care and use of warm-blooded animals for research in the U.S. other than laboratory rats, mice and chickens, and is enforced through periodic inspections by the U.S. Department of Agriculture (USDA). The AWA establishes facility standards regarding several aspects of animal welfare, including housing, ventilation, lighting, feeding and watering, handling, veterinary care, and recordkeeping. CDD complies with licensing and registration requirement standards set by the USDA and similar agencies in foreign jurisdictions such as the European Union and China for the care and use of regulated species. If the USDA determines that CDD’s equipment, facilities, laboratories or processes do not comply with applicable AWA standards, it may issue an inspection report documenting the deficiencies and setting deadlines for any required corrective actions. The USDA may impose fines, suspend and/or revoke animal research licenses or confiscate research animals. Other countries where the Company conducts business have similar laws and regulations with which the Company must also comply.

## Payment for Clinical Laboratory Services

In 2016, LCD derived approximately 15.5% of its net revenue directly from the Medicare and Medicaid programs. In addition, LCD's other commercial 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 healthcare programs, in part because customers 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 healthcare costs, including reducing reimbursement for clinical laboratory services.

Reimbursement under the Medicare CLFS and PFS are capped at different rates in each Medicare Administrative Contractor's jurisdiction. State Medicaid programs are prohibited from paying more than the Medicare fee schedule limit for clinical laboratory services furnished to Medicaid recipients. Laboratories primarily bill and are reimbursed by Medicare and Medicaid directly for covered tests performed on behalf of Medicare and Medicaid beneficiaries; for beneficiaries that participate in Managed Medicare and Managed Medicaid plans, laboratory bills are submitted to and paid by MCOs that manage those plans.

As discussed previously in Item 1 of Part I, over the past several years LCD has experienced a series of reductions in payment from Medicare. In 2017, LCD will receive a net payment increase from Medicare, due to payment increases under the CLFS being greater than offsetting payment reductions under the PFS. On June 23, 2016, CMS issued a final rule to implement PAMA that would require applicable laboratories, including LCD, to begin reporting their test-specific private payer payment amounts to CMS during the first quarter of 2017. CMS intends to use that private market data to calculate weighted median prices for each test (based on applicable CPT codes) that would represent the new CLFS rates beginning in 2018, subject to certain phase-in limits. For 2018-2020, a test price cannot be reduced by more than 10.0% per year; for 2021-2023, a test price cannot be reduced by more than 15.0% per year. The process of data reporting and repricing will be repeated every three years for Clinical Diagnostic Laboratory Tests (CDLTs). The second data reporting period for CDLTs will occur during the first quarter of 2020, and new CLFS rates for CDLTs will be established based on that data beginning in 2021, subject to the previously described phase-in limits for 2021-2023. The third data reporting period for CDLTs will occur during the first quarter of 2023, and new CLFS rates for CDLTs will be established based on that data beginning in 2024. CLFS rates for 2024 and subsequent periods will not be subject to phase-in limits. CLFS rates for Advanced Diagnostic Laboratory Tests (ADLTs) will be updated annually.

Many pathology services performed by LCD are reimbursed by Medicare 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. Such adjustments can impact both the conversion factor and relative value units. The Sustainable Growth Rate (SGR), the formula formerly 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, Congress intervened repeatedly to prevent these payment reductions, and the conversion factor was increased or frozen for the subsequent year. MACRA permanently replaced the SGR formula and transitioned PFS reimbursement to a value-based payment system. MACRA retroactively avoided a 21.2% reduction in PFS reimbursement that had been scheduled for April 1, 2015, and provided for PFS conversion factor increases of 0.5% from July 1, 2015 to December 31, 2015, and 0.5% in each of years 2016-2019, followed by 0.0% updates for 2020-2025, and updates that vary based on participation in alternative payment models in subsequent years. These changes to the conversion factor may be offset by reductions to the relative value units, as was the case with the 2016 PFS reductions. In addition, rates will be adjusted



under the new Merit-Based Incentive Payment System beginning in 2019. Approximately 0.8% of LCD's revenue is reimbursed under the PFS.

Because a significant portion of the Company's costs are relatively fixed, further payment reductions to Medicare, Medicaid and other government programs 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, LCD 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 frequently ordered 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 LCD'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 LCD's ability to be paid for some of the tests it performs. LCD 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 continue to require additional information to process claims or have implemented prior authorization policies. Many commercial payers were delayed in becoming aware of the impact of their claims edits and policies, which impeded access to services that previously have been covered and reimbursed. These delays and changes in coverage had a negative impact on revenue, revenue per requisition, margins and cash flows. The negative impact from these reimbursement challenges was largely sustained through 2016. Similarly, CLFS coding and billing changes related to toxicology and other procedures were implemented in 2016. The Company experienced delays in the pricing and implementation of the new toxicology codes; however, the Company largely overcame issues related to price and margins through direct negotiation with the associated payers. Further coding and billing changes related to toxicology testing and other procedure types are to be implemented in 2017. The Company expects delays in the pricing and implementation of these new codes, and while the impact on price and margins is currently unclear, the Company anticipates that some of that impact will be mitigated by timely negotiation with payers impacted by these changes.

Future changes in national, 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 and Other Personal Information

In the U.S., the Health Insurance Portability and Accountability Act of 1996 (HIPAA) was designed to address issues related to the security and confidentiality of health information and to improve the efficiency and effectiveness of the healthcare system by facilitating the electronic exchange of information in certain financial and administrative transactions. These regulations apply to health plans, physicians that conduct standard transactions electronically and healthcare 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 healthcare provider identifier in connection with certain electronic transactions.

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 believes it has fully adopted the ICD-10-CM code set. While to date the Company has not experienced any sustained disruption in receipts or indications of substantive reductions to reimbursement and net revenues related to the implementation of the ICD-10-CM code set, further future application of restrictive clinical or payment policies could negatively impact the Company. The Company believes it is in compliance in all material respects with applicable laws and regulations for electronic funds transfers and remittance advice 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 Company believes that it is in compliance in all material respects with the requirements of the HIPAA Privacy Rule.

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 Security Rule.



The U.S. Health Information Technology for Economic and Clinical Health Act (HITECH), which was enacted in February 2009, with regulations effective on September 23, 2013, 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 PHI 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 PHI is breached, as that term is defined by HITECH. Business associates are similarly required to notify covered entities of a breach. The Company believes its policies and procedures are fully compliant with the HITECH requirements.

On February 6, 2014, CMS and HHS published final regulations that amended 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. The Company revised its policies and procedures to comply with these new access requirements and updated its privacy notice to reflect individuals' new access rights under this final rule.

The Standard Unique Employer Identifier Rule requires 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 administrative simplification provisions of HIPAA mandate the adoption of standard unique identifiers for healthcare providers. The intent of these provisions is to improve the efficiency and effectiveness of the electronic transmission of health information. The National Provider Identifier Rule requires that all HIPAA-covered healthcare 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 and other provider numbers previously assigned by payers and other entities for the purpose of identifying healthcare providers in standard electronic transactions. The Company believes that it is in compliance with the HIPAA National Provider Identifier Rule in all material respects.

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 similar laws governing the collection, use, disclosure and transmission of personal and/or patient information.

The total cost associated with meeting the ongoing 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 HIPAA regulations described above, there are a number of other national, state and foreign laws regarding the confidentiality and security of medical information, some of which apply to clinical laboratories and CROs. These laws vary widely, but they most commonly regulate or restrict the collection, use and disclosure of medical and financial information and other personal 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. Additionally, numerous other countries have similar laws governing the collection, use, disclosure and transmission of personal and/or patient information. For example, in December 2015, the European Union approved a General Data Protection Regulation (GDPR) to replace Directive 95/46/EC, which will take effect May 25, 2018, governing use and transfer of personal data and imposing penalties for noncompliance.

## Fraud and Abuse Laws and Regulations

Existing U.S. laws governing federal healthcare programs, including Medicare and Medicaid, as well as similar state laws, impose a variety of broadly described fraud and abuse prohibitions on healthcare 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 U.S. 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 U.S., 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 U.S. False Claims Act. Recent amendments to the False Claims Act, as well as other enhancements to the U.S. 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 or Medicaid within 60 days of identification (whether or not paid through any fault of the recipient); 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 11, 2016, CMS issued the final rule clarifying certain aspects of the overpayment requirement for purposes of Medicare, effective on March 14, 2016.

The U.S. healthcare programs' Anti-Kickback Statute prohibits knowingly providing anything of value in return for, or to induce the referral of, Medicare, Medicaid or other U.S. healthcare program business. Violations can result in imprisonment, fines, penalties, and/or exclusion from participation in U.S. healthcare programs. The OIG has published “safe harbor” regulations that specify certain arrangements that are protected from prosecution under the Anti-Kickback Statute 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 Statute; 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 healthcare programs).

From time to time, the OIG issues alerts and other guidance on certain practices in the healthcare industry that implicate the Anti-Kickback Statute or other 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 healthcare providers that raise issues under the U.S. fraud and abuse laws, including the Anti-Kickback Statute. 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 that 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 pickup and disposal of biohazardous 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 healthcare 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 healthcare provider (e.g., physician) may be liable under the Anti-Kickback Statute, 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 long-standing 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 U.S. program business.

The OIG has expressed concern about the provision of discounts on laboratory services billed to customers in return for the referral of U.S. healthcare program business. In a 1999 Advisory Opinion, the OIG concluded that a laboratory's offer to a physician of significant discounts on non-U.S. healthcare program laboratory tests might violate the Anti-Kickback Statute on the basis that such discounts could be viewed as in exchange for referrals by the physician of business to be billed by the laboratory to Medicare at non-discounted rates. In a 1999 correspondence, the OIG stated that a discount that a laboratory offers to a skilled nursing facility for tests billed to the skilled nursing facility to induce the referral of tests for which the laboratory is reimbursed by Medicare would implicate the Anti-Kickback Statute.

The OIG has also issued guidance in 1989 and 2003 regarding joint venture arrangements that may be viewed as suspect under the Anti-Kickback Statute. These documents have relevance to clinical laboratories that are part of (or are considering establishing) joint ventures with potential sources of U.S. healthcare program business. 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 where the physicians’ financial and business risk in the venture was minimal and the physicians would contract out substantially all laboratory operations, committing very little in the way of financial, capital, or human resources.

Violations of other fraud and abuse laws can also result in exclusion from participation in U.S. healthcare 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 a June 18, 2007 withdrawal of proposed rulemaking, the OIG stated that it would continue evaluating billing patterns on a case-by-case basis, noting that it is



“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 from providers that routinely charge Medicare or Medicaid substantially more than their other customers” and that it will use “all tools available … to address instances where Medicare or Medicaid are charged substantially more than other payers.” An enforcement action by the OIG under this statutory exclusion basis or an enforcement action by Medicaid officials of similar state law restrictions could have an adverse effect on the Company.

Under another U.S. statute, known as the Stark Law or “self-referral” prohibition, physicians who have a financial or a compensation relationship with a commercial 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: i) fair market value compensation for the provision of items or services; ii) payments by physicians to a laboratory for commercial laboratory services; iii) ancillary services (including laboratory services) provided within the referring physician's own office, if certain criteria are satisfied; iv) physician investment in a company whose stock is traded on a public exchange and has stockholder equity exceeding $75.0 million; and v) certain space and equipment rental arrangements that are set at a fair market value rate and satisfy other requirements. Many states have their own self-referral laws as well, which in some cases apply to all patient referrals, not just government reimbursement programs.

There are a variety of other types of U.S. 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 U.S. 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 U.S. or state healthcare programs, significant criminal and civil fines and penalties, and loss of licensure. Any exclusion from participation in a U.S. healthcare program, or material 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 national, state and local laws and regulations relating to the protection of the environment, and human health and safety 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 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 U.S. Occupational Safety and Health Administration (OSHA) has established extensive requirements relating to workplace safety for healthcare employers, including clinical laboratories, whose workers may be exposed to blood-borne pathogens such as HIV, HCV and hepatitis B virus (HCB). 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. Other countries where the Company conducts business have similar laws and regulations concerning the environment and human health and safety with which the Company must also comply.

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

The Company seeks to comply with all relevant environmental and human health and safety 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 U.S. 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 U.S. 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 U.S. Drug Enforcement Administration. CDD handles controlled substances as part of the services it provides in preclinical testing and clinical trials.



## Compliance Program

The Company maintains a comprehensive, global compliance program that includes ongoing evaluation and monitoring of its compliance with the laws and regulations of the U.S. and the other countries in which it has operations. The objective of the Company’s compliance program is to develop, implement and update compliance safeguards, as appropriate. Emphasis is placed on developing and implementing compliance policies and guidelines, personnel training programs and monitoring and auditing activities.

The Company seeks to conduct its business in compliance with all statutes, regulations, and other requirements applicable to its clinical laboratory operations and drug development business. The clinical laboratory industry and drug development industries are, 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

Investors should carefully consider all of the information set forth in this report, including the following risk factors, before deciding to invest in any of the Company’s securities. The risks below are not the only ones that the Company faces. Additional risks not presently known to the Company, or that the Company presently deems immaterial, may also negatively impact the Company. The Company’s business, consolidated financial condition, revenues, results of operations, profitability, reputation or cash flows could be materially impacted by any of these factors.

This report also includes forward-looking statements that involve risks or uncertainties. The Company’s results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks described below and elsewhere. See “Forward-Looking Statements” in Item 7.

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

U.S. and state government payers, such as Medicare and Medicaid, as well as insurers, including managed care organizations (MCOs), have increased their efforts to control the cost, utilization and delivery of healthcare services. From time to time, Congress has considered and implemented changes in 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, diagnosis code and other claims edits, or a physician or qualified practitioner’s signature on test requisitions, may be implemented from time to time. Reimbursement for pathology services performed by LCD 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 commercial laboratory industry by adding more complex new regulatory and administrative requirements. Further changes in third-party payer regulations, policies, or laboratory benefit or utilization management programs may have a material adverse impact on LCD’s business. Actions by federal and state agencies regulating insurance, including healthcare exchanges, or changes in other laws, regulations, or policies may also have a material adverse effect upon LCD’s business.

The Company could face significant monetary damages and penalties and/or exclusion from government programs if it violates federal, state, local or international laws including, but not limited to, anti-fraud and abuse laws.

The Company is subject to extensive government regulation at the U.S. 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 (CLIA), or those of Medicare, Medicaid or other national, state or local agencies in the U.S. and other countries where the Company operates laboratories.

The commercial laboratory testing industry is subject to extensive U.S. regulation, and many of these statutes and regulations have not been interpreted by the courts. CLIA extends federal oversight to virtually all clinical laboratories operating in the U.S.



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 Company also operates laboratories outside of the U.S. and is subject to laws governing its laboratory operations in the other countries where it operates.

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, 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.

FDA regulation of diagnostic products and increased FDA regulation of LDTs could result in increased costs and the imposition of fines or penalties and have a material adverse effect upon the Company’s business.

The FDA has regulatory responsibility for instruments, test kits, reagents and other devices used by clinical laboratories. The FDA enforces laws and regulations that govern the development, testing, manufacturing, performance, labeling, advertising, marketing, distribution and surveillance of diagnostic products, and it regularly inspects and reviews the manufacturing processes and product performance of diagnostic products. LCD’s point-of-care testing devices are subject to regulation by the FDA.

There are other regulatory and legislative proposals that would increase general FDA oversight of clinical laboratories and LDTs. On July 26, 2007, the FDA issued Draft Guidance for Industry, Clinical Laboratories, and FDA Staff: In Vitro Diagnostic Multivariate Index Assays. The guidance proposed certain changes to the agency's general past practice regarding the regulation of certain LDTs and announced that most devices deemed to be In Vitro Diagnostic Multivariate Index Assays (IVDMIs) would either be Class II or Class III devices, although it is possible that an IVDMIA for a low-risk indication could be Class I. Class II medical devices typically require FDA clearance or a premarket notification submission. Class III devices require the submission of an application for Premarket Approval. On October 3, 2014, the FDA published two additional draft guidance documents: Framework for Regulatory Oversight of Laboratory Developed Tests (LDTs), which provides an overview of how the FDA would regulate LDTs through a risk-based approach, and FDA Notification and Medical Device Reporting for Laboratory Developed Tests, which describes the process for clinical laboratories to notify the FDA of the LDTs they "manufacture" and describes the Medical Device Reporting requirements for LDTs. On May 28, 2015, and October 22, 2015, the House Energy and Commerce Health Subcommittee released discussion drafts of a bill that would reform oversight of in vitro clinical tests (IVCTs), including both LDTs and test kits. The bill would establish a new regulatory framework in which FDA would regulate IVCTs under a new category separate from medical devices, and CMS regulation of laboratories under CLIA would be modernized. On November 16, 2015, the FDA issued a report titled, The Public Health Evidence for FDA Oversight of Laboratory Developed Tests: 20 Case Studies (LDT Report). The LDT Report compiles 20 case studies involving LDTs where FDA alleges that noncompliance with FDA regulations led to serious issues, such as false-positive or false-negative results, causing potential or actual harm to patients. On December 29, 2015, FDA published notice of its intent to finalize guidance on its policy for regulatory oversight of LDTs in 2016. However, on November 18, 2016, the FDA announced it would not release final guidance at this time and instead would continue to work with stakeholders, the new administration and Congress to determine the right approach, and on January 13, 2017, the FDA released a discussion paper outlining a possible risk-based approach for FDA and CMS oversight of LDTs. There are other regulatory and legislative proposals that would increase general FDA oversight of clinical laboratories and LDTs. The outcome and ultimate impact of such proposals on the business is difficult to predict at this time.

Current FDA regulation of the Company’s diagnostic products and potential future increased regulation of the Company’s LDTs could result in increased costs and administrative and legal actions for noncompliance, including warning letters, fines, penalties, product suspensions, product recalls, injunctions and other civil and criminal sanctions, which could have a material adverse effect upon the Company.

Failure to comply with U.S., state, local or international environmental, health and safety laws and regulations, including the U.S. Occupational Safety and Health Administration Act and the U.S. 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.

As previously discussed in Item 1 of Part I of this report, the Company is subject to licensing and regulation under 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. Failure to comply with these laws and regulations could subject the Company to denial of the right to conduct business, fines, criminal penalties and/or other enforcement actions that would have a material adverse effect on its business. In addition, compliance with future legislation could impose additional requirements on the Company that may be costly.



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

The Company implemented Version 5010 of the HIPAA Transaction Standards and believes it has fully adopted the ICD-10-CM Code Set. Clinical laboratories are typically required to submit healthcare 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 apply the new code set could have an adverse impact on reimbursement, days sales outstanding and cash collections.

Failure to comply with privacy and security laws and regulations could result in fines, penalties and damage to the Company’s reputation with customers and have a material adverse effect upon the Company’s business.

If the Company does not comply with existing or new laws and regulations related to protecting the privacy and security of personal or health information, it could be subject to monetary fines, civil penalties or criminal sanctions.

In the U.S., the HIPAA privacy and security regulations, including the expanded requirements under HITECH, establish comprehensive standards with respect to the use and disclosure of protected health information (PHI) by covered entities, in addition to setting standards to protect the confidentiality, integrity and security of PHI.

HIPAA restricts the Company’s ability to use or disclose patient identifiable laboratory data, without patient authorization, for purposes other than payment, treatment or healthcare operations (as defined by HIPAA), except for disclosures for various public policy purposes and other permitted purposes outlined in the privacy regulations. HIPAA and HITECH provide for significant fines and other penalties for wrongful use or disclosure of PHI in violation of the privacy and security regulations, including potential civil and criminal fines and penalties. The regulations establish a complex regulatory framework on a variety of subjects, including:

- The circumstances under which the use and disclosure of PHI 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 healthcare operations activities;

• A patient’s rights to access, amend and receive an accounting of certain disclosures of PHI;

• The content of notices of privacy practices for PHI;

• Administrative, technical and physical safeguards required of entities that use or receive PHI; and

• The protection of computing systems maintaining electronic PHI.

The Company has implemented policies and procedures designed to comply with the HIPAA privacy and security requirements as applicable. 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 additional federal privacy and security regulations and varying state privacy and security laws. In addition, 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 health information or other personal information.

The Company may also be required to comply with the data privacy and security laws of other countries in which it operates or from which it receives data transfers. For example, in Europe both criminal and administrative sanctions are possible for violation of EU member state implementations of the general data protection Directive 95/46/EC. In December 2015, the EU enacted a General Data Protection Regulation (GDPR) to replace Directive 95/46/EC, which will take effect May 25, 2018, and which has a broader application and enhanced penalties for noncompliance. The Company is evaluating the scope of work required to comply with the new EU regulations, and as a result of that evaluation expects to make changes to its business practices and to incur additional costs.

Regulations requiring the use of standard transactions for healthcare 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 healthcare 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, could prove technically difficult, time-consuming or expensive to implement. 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. While 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, it may not be successful in these efforts.

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 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 and the imposition of fines and penalties.

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 commercial 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 R&D 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 healthcare providers (including physician assistants, nurse practitioners and certified nurse midwives, generally referred to herein as physicians) 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 commercial 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 it has taken responsibility from the U.S. Centers for Disease Control and Prevention 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.

Healthcare reform and changes to 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.

LCD's testing services are billed to MCOs, Medicare, Medicaid, physicians and physician groups, hospitals, patients and employer groups. 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 who ordered the test. Increases in the percentage of services billed to government and MCOs could have an adverse impact on the Company's net revenues.

The Company serves many MCOs. These organizations 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 some cases, those fee structures are specific to independent clinical laboratories, while the fees paid to hospital-based and physician-office laboratories may be different, and are typically higher. MCOs may also offer Managed Medicare or Managed Medicaid.



plans. In addition, some MCOs use capitation rates to fix the cost of laboratory testing services for their enrollees. Under a capitated reimbursement arrangement, the clinical laboratory receives a per-member, per-month payment for an agreed upon menu of laboratory tests provided to MCO members during the month, regardless of the number of tests performed.

Capitation shifts the risk of increased test utilization (and the underlying mix of testing services) to the commercial 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, 2016, such capitated contracts accounted for approximately $225.8 million, or 3.4%, of the Company's LCD net revenues.

The Company's ability to attract and retain MCOs is critical given the impact of healthcare reform, related products and expanded coverage (e.g. health insurance exchanges and Medicaid expansion) and evolving delivery models (e.g., ACOs).

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

In addition, Medicare and Medicaid and private insurers have increased their efforts to control the cost, utilization and delivery of healthcare services, including commercial laboratory services. Measures to regulate healthcare delivery in general, and clinical laboratories in particular, have resulted in reduced prices, added costs and decreased test utilization for the commercial 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 Managed Medicare plans has increased. The percentage of Medicaid beneficiaries enrolled in Managed Medicaid plans has also increased, and is expected to continue to increase; however, changes to, or repeal of, the ACA may continue to affect coverage, reimbursement, and utilization of laboratory services, as well as administrative requirements, in ways that are currently unpredictable. Further, structural reforms of Medicare that could occur under the 115th Congress and the new administration, such as the imposition of uniform coinsurance and the combination of the Medicare Part A and Part B deductibles, could adversely affect laboratory reimbursement under Medicare.

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. These issues (particularly payer policy changes) and changes in coverage had a negative impact on revenue, revenue per requisition, and margins and cash flows in 2014 through 2016, and are expected to have a continuing negative impact. Similarly, CLFS coding and billing changes related to toxicology and other procedures were implemented in 2016. The Company experienced delays in the pricing and implementation of the new toxicology codes; however, the Company largely overcame issues related to price and margins through direct negotiation with the associated payers. Further coding and billing changes related to toxicology and other procedure types are expected to be implemented in 2017. The Company expects delays in the pricing and implementation of these new codes. While the impact on price and margins is currently unclear, the Company anticipates that some of that will be mitigated by timely negotiation with payers impacted by these changes.

In addition, some MCOs are implementing, directly or through third parties, various types of laboratory benefit management programs that may include lab networks, utilization management tools (such as prior authorization and/or prior notification), and claims edits, which may impact coverage or reimbursement for commercial laboratory tests. Some of these programs address commercial laboratory testing broadly, while others are focused on molecular and genetic testing.

The Company expects the efforts to impose reduced reimbursement, more stringent payment policies, and utilization and cost controls by government and other payers to continue. If LCD 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. In 2014, Congress passed PAMA, requiring Medicare to change the way payment rates are calculated for tests paid under the CLFS, and to base the payment on the weighted median of rates paid by private payers. On June 23, 2016, CMS published a final rule to implement PAMA. This rule requires applicable laboratories, including LCD, to begin reporting their test-specific private payer payment amounts to CMS during the first quarter of 2017, which CMS would then use to calculate new CLFS rates that would be effective January 1, 2018.

Healthcare reform legislation also contains numerous regulations that will require the Company, as an employer, to implement significant process and record-keeping changes to be in compliance. These changes increase the cost of providing healthcare coverage to employees and their families. Given the limited release of regulations to guide compliance, as well as the potential repeal and replacement of the ACA in the 115th Congress, the exact impact to employers, including the Company, is uncertain.

Changes in government regulation or in practices relating to the biopharmaceutical industry could decrease the need for certain services that CDD provides.

CDD assists biopharmaceutical companies in navigating 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 CDD has difficulty satisfying or that make its services less competitive, could eliminate or substantially reduce the demand for its services. Also, if government efforts to contain drug costs impact biopharmaceutical company profits from new drugs, or if health insurers were to change their practices with respect to reimbursement for biopharmaceutical products, some of CDD’s customers may spend less, or reduce their growth in spending on R&D.

On December 13, 2016, President Obama signed into law the 21st Century Cures Act. This Act provides funding designed to increase government spending on certain drug development initiatives; contains several provisions designed to help make the drug development process more streamlined and efficient; and allows the FDA to increase staffing to support drug development, review and regulation. These provisions should be helpful to biopharmaceutical companies and CROs, including CDD, to the extent that they capitalize on the use of data, adaptive trial designs, real-world evidence, biomarkers and other development tools that are accepted by the FDA.

In addition, implementation of healthcare reform legislation that adds costs could limit the profits that can be made from the development of new drugs. This could adversely affect R&D expenditures by biopharmaceutical companies, which could in turn decrease the business opportunities available to CDD both in the U.S. and other countries. New laws or regulations may create a risk of liability, increase CDD costs or limit service offerings through CDD.

Failure to comply with the regulations of the U.S. FDA and other drug regulatory agencies, such as the Medicines and Healthcare products Regulatory Agency in the U.K., the European Medicines Agency, the China Food and Drug Administration, and the Pharmaceuticals and Medical Devices Agency in Japan, could result in sanctions and/or remedies against CDD and have a material adverse effect upon the Company.

The operation of CDD's preclinical laboratory facilities and clinical trial operations must conform to GLP and GCP, as applicable, as well as all other applicable standards and regulations, as further described in "Business" in Item 1 of this report.

Additionally, certain CDD services and activities must conform to cGMP as further described in "Business" in Item 1 of this report. Failure to maintain compliance with GLP, GCP, or cGMP regulations and other applicable requirements of various regulatory agencies could result in warning letters, fines, unanticipated compliance expenditures, suspension of manufacturing, and civil, criminal or administrative sanctions and/or remedies against CDD, including suspension of its laboratory operations, which could have a material adverse effect upon the Company.

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

Both LCD and CDD operate in highly competitive industries. The commercial 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 physicians and third-party payers in selecting a laboratory. As a result of significant consolidation in the commercial laboratory industry, larger commercial laboratory providers are able to increase cost efficiencies afforded by large-scale automated testing. This consolidation results in greater price competition. LCD 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.

Competitors in the CRO industry range from hundreds of smaller CROs to a limited number of large CROs with global capabilities. CDD’s main competition consists of these small and large CROs, as well as in-house departments of biopharmaceutical companies and, to a lesser extent, select universities and teaching hospitals. CDD competes on a variety of factors, including:

• Reputation for quality, timely performance and regulatory compliance;

- Expertise and experience in operations, efficiency of drug development processes, technology, therapeutic areas, and market access services;

• Scope of service offerings;

• Strengths in various geographic markets;

• Price;

• Quality of facilities;

• Ability to acquire, process, analyze and report data in a rapid and accurate manner;

• Quality of relationships;

- Ability to manage large-scale clinical trials both domestically and internationally, including the recruitment of appropriate and sufficient clinical trial subjects; and

• Size and scale.

CDD’s services have from time to time experienced periods of increased price competition that had an adverse effect on a



segment's profitability and consolidated net revenues and net income.

There is competition among CROs for both customers and potential acquisition candidates. Additionally, entities considering entering the CRO industry will find few barriers to entry, thus further increasing possible competition. These competitive pressures may affect the attractiveness of CDD’s services and could adversely affect its financial results and the financial results of the Company.

Failure to obtain and retain new customers, the 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/or 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 commercial laboratory services and to otherwise maintain and grow its business, 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, a decrease in demand for the Company's services from existing customers, or the loss of existing contracts, 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 services, reporting and information systems, reputation in the medical community and the drug development industry, 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 healthcare 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. LCD has a well-established base of relationships with those systems and networks, including collaborative agreements. LCD's inability to retain its existing relationships with those physicians as they become part of healthcare systems and networks and/or to create new relationships could impact its ability to successfully grow its business.

Continued and increased consolidation of MCOs, biopharmaceutical companies, health systems, physicians and other customers could adversely affect the Company's business.

Many healthcare companies and providers, including MCOs, biopharmaceutical companies, health systems and physician practices are consolidating through mergers, acquisitions, joint ventures and other types of transactions and collaborations. As the healthcare industry consolidates, competition to provide goods and services may become more intense. This competition and increased customer bargaining power may adversely affect the price and volume of the Company’s services.

LCD’s nutritional chemistry and food safety business exposes the Company to various risks, including liability for errors and omissions in work conducted for LCD customers.

LCD offers a range of product-development and product-integrity services to food and beverage manufacturers and retailers, industry organizations and academic institutions. LCD expects to expand its nutritional chemistry and food safety business by leveraging the Company’s expertise in microbiology and its infrastructure to enable testing to be performed close to the food source. LCD also is exploring the possibility of developing point-of-production testing for food safety. These business offerings and opportunities expose the Company to many of the same, or similar, risks that are applicable to other business activities of the Company, including with respect to the operations of its facilities and compliance with applicable laws and regulations. The agricultural, food, beverage and dietary supplement industries are continuing to gain the attention of governments and regulators around the world, and regulations and applicable laws have increased in recent years. For example, many food and beverage manufacturers and retailers will be subject to new nutrition labeling regulations and new food manufacturing requirements, including regulations issued under the Food Safety Modernization Act (FSMA). With these enhanced requirements on the Company’s customers, there is an increased risk that errors in or omissions from nutritional analysis and food safety tests conducted by the Company for its customers could result in liability for the Company under customer contracts. If LCD determines to further expand its nutritional chemistry and food safety testing business in the future beyond what is currently anticipated, LCD could become subject to additional standards and regulations, including under the FSMA, and could face additional liabilities resulting from new and pending regulatory and other legal decisions.

Changes or disruption in services or supplies provided by third parties, including transportation, could adversely affect the Company’s business.

The Company depends on third parties to provide services critical to the Company’s business. The Company’s laboratories and certain of the Company’s other businesses are heavily reliant on air travel for transport of clinical trial and diagnostic testing supplies and specimens, research products, and people, and a significant disruption to the air travel system, or the Company’s access to it, could have a material adverse effect on the Company’s business. CDD depends on a limited number of suppliers for certain services and for certain animal populations. Disruptions to the continued supply of these services, products or animal



populations may arise from export/import restrictions or embargoes, political or economic instability, pressure from animal rights activists, adverse weather, natural disasters or other causes. Disruption of supply could have a material adverse effect on the Company’s business.

## Damage or disruption to the Company’s facilities could adversely affect the Company’s business.

Many of the Company’s facilities would be difficult to replace in a short period of time. Any event that causes a disruption of the operation of these facilities might impact the Company’s ability to provide service to customers and, therefore, could have a material adverse effect on the Company’s financial condition, results of operations and cash flows.

The Company bears financial risk for contracts that, for reasons beyond the Company's control, may be underpriced, subject to cost overruns, delayed, or terminated or reduced in scope.

The Company has many contracts that are structured as fixed-price for fixed-contracted services or fee-for-service with a cap. The Company bears the financial risk if these contracts are underpriced or if contract costs exceed estimates. Such underpricing or significant cost overruns could have a material adverse effect on the Company's business, results of operations, financial condition and cash flows.

Many of CDD’s contracts, in particular, 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:

• Failure of products to satisfy safety requirements;

• Unexpected or undesired results of the products;

• Insufficient clinical trial subject enrollment;

• Insufficient investigator recruitment;

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

• CDD’s failure to perform its duties properly under the contract.

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, the loss, reduction in scope or delay of a large contract or the loss, delay or conclusion of multiple contracts could materially adversely affect CDD.

## Contract research services in the drug development industry create liability risks.

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

- Errors or omissions that create harm to clinical trial subjects during a trial or to consumers of a drug after the trial is completed and regulatory approval of the drug has been granted;

- 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 physicians;

- Risks that animals in CDD’s breeding facilities may be infected with diseases that may be harmful and even lethal to themselves and humans despite preventive measures contained in CDD’s 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.

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

While CDD endeavors to include in its contracts provisions entitling it to be indemnified and entitling it to a limitation of liability, these provisions do not uniformly protect CDD against liability arising from certain of its own actions. CDD 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 which must indemnify it does not fulfill its indemnification obligations, or in the event that CDD is not successful in limiting its liability or in the event that the damages and costs exceed CDD's insurance coverage. There can be no assurance that CDD will be able to maintain sufficient insurance coverage on acceptable terms.

## 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, contract disputes, professional liability and employee-related matters. The Company may also receive inquiries and requests for information from governmental agencies and bodies, including 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.



## The Company's quarterly operating results may vary.

The Company's operating results, particularly for CDD, may vary significantly from quarter to quarter and are influenced by factors over which the Company has little control, such as:

• Changes in the general global economy;

• Exchange rate fluctuations;

• The commencement, completion, delay or cancellation of large projects or groups of projects;

• The progress of ongoing projects;

• The timing of and charges associated with completed acquisitions or other events; and

• Changes in the mix of the Company's services.

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

The failure to successfully obtain, maintain and enforce intellectual property rights and defend against challenges to the Company’s intellectual property rights could adversely affect the Company.

Many of the Company’s services, products and processes rely on intellectual property, including patents, copyrights, trademarks and trade secrets. In some cases, that intellectual property is owned by another party and licensed to the Company, sometimes exclusively. The value of the Company’s intellectual property relies in part on the Company’s ability to maintain its proprietary rights to such intellectual property. If the Company is unable to obtain or maintain the proprietary rights to its intellectual property, if it is unable to prevent attempted infringement against its intellectual property, or if it is unable to defend against claims that it is infringing on another party’s intellectual property, the Company could be adversely affected. These adverse effects could include the Company having to abandon, alter and/or delay the deployment of products, services or processes that rely on such intellectual property; having to procure and pay for licenses from the holders of intellectual property rights that the Company seeks to use; and having to pay damages, fines, court costs and attorney’s fees in connection with intellectual property litigation.

## CDD’s revenues depend on the biopharmaceutical industry.

CDD’s revenues depend greatly on the expenditures made by the biopharmaceutical industry in R&D. In some instances, biopharmaceutical companies are reliant on their ability to raise capital in order to fund their R&D projects. Biopharmaceutical companies are also reliant on reimbursement for their products from government programs and commercial payers. Accordingly, economic factors and industry trends affecting CDD’s customers in these industries may also affect CDD. If these companies were to reduce the number of R&D projects they conduct or outsource, whether through the inability to raise capital, reductions in reimbursement from governmental programs or commercial payers, industry trends, economic conditions or otherwise, CDD could be materially adversely affected.

## Actions of animal rights activists may have an adverse effect on the Company.

CDD’s preclinical services utilize animals in preclinical testing of the safety and efficacy of drugs. Such activities are required for the development of new medicines and medical devices under regulatory regimes in the U.S., Europe, Japan and other countries. CDD also breeds and sells animals for biomedical research. Acts of vandalism and other acts by animal rights activists who object to the use of animals in drug development could have an adverse effect on the Company.

Animal populations may suffer diseases that can damage CDD'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, cause loss of animals in CDD’s inventory, result in harm to humans or outside animal populations if the disease is not contained to animals in inventory, or result in other losses. Such results could harm CDD’s reputation or have an adverse effect on CDD’s financial condition, results of operations, and cash flows.

Failure to conduct animal research in compliance with animal welfare laws and regulation could result in sanctions and/or remedies against CDD and have a material adverse effect upon the Company.

The conduct of animal research at CDD’s facilities must be in compliance with applicable laws and regulations in the jurisdictions in which those activities are conducted. These laws and regulations include the AWA, which governs the care and use of warm-blooded animals for research in the U.S. other than laboratory rats, mice and chickens, and is enforced through periodic inspections by the USDA. The AWA establishes facility standards regarding several aspects of animal welfare, including housing, ventilation, lighting, feeding and watering, handling, veterinary care and recordkeeping. Similar laws and regulations



apply in other jurisdictions in which CDD conducts animal research, including the European Union and China. CDD complies with licensing and registration requirement standards set by these laws and regulations in the jurisdictions in which it conducts animal research. If an enforcement agency determines that CDD’s equipment, facilities, laboratories or processes do not comply with applicable standards, it may issue an inspection report documenting the deficiencies and setting deadlines for any required corrective actions. For noncompliance, the agency may take action against CDD that may include fines, suspension and/or revocation of animal research licenses, or confiscation of research animals.

## 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 drug development facilities 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 and in drug development 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 commercial 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, work stoppages or failure to comply with labor or employment laws could adversely affect the Company’s operations and have a material adverse effect upon the Company’s business.

The Company is a party to collective bargaining agreements with various labor unions and is subject to employment and labor laws and unionization activity in the U.S. and other countries in which it conducts business. Disputes with regard to the terms of these agreements, potential inability to negotiate acceptable contracts with these unions, unionization activity, or a failure to comply with labor or employment laws could result in, among other things, labor unrest, strikes, work stoppages, slowdowns by the affected workers, fines and penalties. If any of these events were to occur, 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, or changes in labor or employment laws, 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 LCD's or CDD's days sales outstanding could have an adverse effect on the Company's business, including its cash flow, by increasing its bad debt or decreasing 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, LCD is experiencing increasing patient responsibility as a result of managed care fee-for-service plans that continue to increase deductibles, coinsurance and patient copayments. A material increase in LCD’s days sales outstanding level could have an adverse effect on the Company’s business, including potentially increasing its bad debt rate and decreasing its cash flows. Although CDD does not face the same level of complexity in its billing process, it could also experience delays in billing or collection, and a material increase in CDD’s days sales outstanding could have an adverse effect on the Company’s business, including potentially decreasing its cash flows.

Failure in the Company’s information technology systems or delays or failures in the development and implementation of the Company’s LabCorp Link platform could significantly increase testing turnaround time or billing processes and otherwise disrupt the Company’s operations or customer relationships.

The Company’s 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 operations could disrupt the Company’s ability to process laboratory requisitions, perform testing, provide test results or drug development data in a timely manner and/or bill the appropriate party. The Company is also continuing to enhance its LabCorp Link 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.

Hardware and software failures, delays in the operation of computer and communications systems, the failure to implement new systems or system enhancements to existing systems, and 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,



customer 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 the Company's various computer facilities could result in interruptions in the flow of data to the servers and from the servers to customers. 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 customers. Additionally, significant delays in the planned delivery of system enhancements, or 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.

Security breaches and unauthorized access to the Company’s or its customers’ data could harm the Company’s reputation and adversely affect its business.

The risk exists that experienced computer programmers and hackers could attack and potentially penetrate the Company’s layered security controls and misappropriate or compromise personal information or proprietary or confidential information, create system disruptions or cause shutdowns. They also may be able to develop and deploy viruses, worms and other malicious software programs that attack the Company’s systems or otherwise exploit any security vulnerabilities. Outside parties may also attempt to fraudulently induce employees to take actions, including the release of confidential or sensitive information or to make fraudulent payments through illegal electronic spamming, phishing or other tactics. Although the Company believes that it has robust information security procedures and other safeguards in place, which are monitored and routinely tested internally and by external parties, because the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently and often are not recognized until launched against a target, the Company may be unable to anticipate all of these techniques or to implement adequate preventive measures. In addition, as cyber threats continue to evolve, the Company may be required to expend additional resources to continue to enhance the Company’s information security measures or to investigate and remediate any information security vulnerabilities. The Company’s remediation efforts may not be successful and could result in interruptions, delays or cessation of service. Breaches of the Company’s security measures and the unauthorized dissemination of personal, proprietary or confidential information about the Company or its customers or other third-parties could expose customers’ private information. Such breaches could expose customers to the risk of financial or medical identity theft or expose the Company or other third-parties to a risk of loss or misuse of this information, result in litigation and potential liability for the Company, damage the Company’s brand and reputation or otherwise harm the Company’s business. Any of these disruptions or breaches of security could have a material adverse effect on the Company’s business, regulatory compliance, financial condition and results of operations.

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

Natural disasters may result in a temporary decline of volumes in both segments. In addition, such events may temporarily interrupt the Company’s ability to transport specimens, the Company’s ability to efficiently commence studies, 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, drug development services, cash collections and the availability of credit.

The Company’s operations are dependent upon ongoing demand for diagnostic testing and drug development services by patients, physicians, hospitals, MCOs, biopharmaceutical companies and others. A significant downturn in the economy could negatively impact the demand for diagnostic testing and drug development services, as well as the ability of customers to pay for services rendered. 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.

Foreign currency exchange fluctuations could have an adverse impact on the Company’s business.

The Company has business and operations outside the U.S., and CDD derives a significant 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, CDD 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 CDD's



results of operations, financial condition and cash flows. Foreign currency exchange fluctuations could have an adverse impact on the Company’s business.

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

The Company's international operations expose 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, but not limited to, compliance with the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act and other international anti-corruption laws; changes in reimbursement by foreign governments for services provided by the Company; compliance with export controls and trade regulations; changes in tax policies or other foreign laws; compliance with foreign labor and employee relations laws and regulations; restrictions on currency repatriation; judicial systems that less strictly enforce contractual rights; countries that do not have clear or well-established laws and regulations concerning issues relating to commercial laboratory testing or drug development services; 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.

Changes in tax laws and regulations or the interpretation of such may have a significant impact on the financial position, results of operations and cash flows of the Company.

U.S. and foreign governments continue to review, reform and modify tax laws, including with respect to the Organisation for Economic Co-operation and Development’s base erosion and profit shifting initiative. Changes in tax laws and regulations could result in material changes to the domestic and foreign taxes that the Company is required to provide for and pay.

In addition, the Company is subject to regular audits with respect to its various tax returns and processes in the jurisdictions in which it operates. Errors or omissions in tax returns, process failures or differences in interpretation of tax laws by Tax authorities and the Company may lead to litigation, payments of additional taxes, penalties and interest.

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 and enhance therapeutic expertise, enhance esoteric testing and global drug development capabilities, and increase presence in key geographic areas. Since 2010, the Company has invested net cash of approximately $6.3 billion and equity of $1.8 billion in strategic business acquisitions ($2.7 billion over the same period excluding the Acquisition). 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.

The Company’s level of indebtedness could adversely affect the Company’s liquidity, results of operations and business.

At December 31, 2016, indebtedness on the Company's outstanding senior notes totaled approximately $5,200.0 million in aggregate principal. The Company is also a party to credit agreements relating to a $1.0 billion revolving credit facility and a term loan with a principal balance of $565.0 million as of December 31, 2016. Under the term loan facility and the revolving credit



facility, 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 declines over time.

The Company’s level of indebtedness 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, including large acquisitions.

The Company may also enter into additional transactions or credit facilities, including other long-term debt, which may increase its indebtedness and result in additional restrictions upon the business. In addition, major debt rating agencies regularly evaluate the Company's debt based on a number of factors. There can be no assurance that the Company will be able to maintain its existing debt ratings, and failure to do so could adversely affect the Company's cost of funds, liquidity and access to capital markets.

Failure to successfully integrate the business of Covance or to realize the expected benefits of the Acquisition could have a material adverse impact on the Company’s business, net revenues and profitability and the market price of its common stock.

If the Company fails to successfully complete the integration of Covance into its existing operations or is not able to achieve the anticipated benefits of the Acquisition and integration, 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; inconsistencies in standards, controls, procedures and policies; or disruptions in its relationships with suppliers and other parties with which it deals that could adversely affect the Company’s ability to maintain relationships with customers and employees or to achieve the anticipated benefits of the Acquisition. Integration efforts could also place a significant burden on the Company’s management, employees and internal resources, which could otherwise have been devoted to other business opportunities and improvements.

The ongoing success of the transaction will depend, in significant part, on the Company’s ability to realize the anticipated benefits from the Acquisition, including the opportunity for revenue growth in the 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 may be lower than the Company expects and may take longer to achieve than anticipated, and expenses may be higher than the Company expects. The Company has made certain assumptions relating to the Acquisition and integration that may prove to be materially inaccurate, including:

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

• Projections of the business and CDD's future financial performance;

- Timing and total costs of integrating a large number of processes, policies, procedures, operations, technologies and systems;

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

• The Company’s ability to develop, maintain and deepen relationships with CDD’s customers; and

• Other financial and strategic risks of the Acquisition.

If one or more of these assumptions are incorrect, such efforts could have a material adverse effect on the Company’s business and operating results, and the value of its common stock may be adversely affected.

In addition, although CDD is subject to many of the same risks and uncertainties that LCD faces in its business, the Acquisition 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. CDD’s business could react differently to economic and other external factors than LCD’s. The Company faces the risk that it will not be successful with these new products and services or in these new markets.

Global economic conditions and government and regulatory changes, including, but not limited to, the United Kingdom’s announced intention to exit from the European Union, could adversely impact the Company’s business and results of operations.

The Company could be adversely impacted due to the consequences of changes in the economy, governments or regulations across the globe. In June 2016, a majority of voters in the United Kingdom elected to withdraw from the European Union (often referred to as Brexit) in a national referendum. Although the referendum was advisory, the current United Kingdom government has indicated its intention to abide by the referendum and to initiate withdrawal proceedings in the near future. The terms of any withdrawal are subject to a negotiation period that could last at least two years after the government of the United Kingdom formally initiates a withdrawal process. This will be either accompanied or followed by negotiations between the European Union and the United Kingdom concerning the future relations between the parties. This could introduce uncertainty with respect to the laws and regulations that will apply in the event of a withdrawal. However, until the Brexit negotiation process is completed, it is difficult to anticipate how the clinical trial landscape in the United Kingdom might change in the next several years.



## Index

This type of development or other government or regulatory change could depress economic activity, which could adversely impact the Company’s business, financial condition and results of operations. This could include long-term volatility in the currency markets and long-term detrimental effects on the value of affected currencies.

All of the Company’s primary laboratory and drug development facilities have been built or improved for the purpose of providing commercial laboratory testing or drug development services. The Company believes that these facilities are suitable and adequate and have sufficient production capacity for the Company's 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 (dollars in millions)

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; commercial and contract disputes; professional liability; employee-related matters; and inquiries, including subpoenas and other civil investigative demands, from governmental agencies, Medicare or Medicaid payers and MCOs 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 parties, including physicians and other healthcare providers (e.g. physician assistants and nurse practitioners, generally referred to herein as physicians). The Company works cooperatively to respond to appropriate requests for information.

The Company also is 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 U.S., federal or state healthcare 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 healthcare field today.

The Company believes that it is in compliance in all material respects with all statutes, regulations and other requirements applicable to its commercial laboratory operations and drug development support services. The healthcare diagnostics and drug development industries are, 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 the 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 in preliminary stages, and many of these cases seek an indeterminate amount of damages. The Company records an aggregate legal reserve, which is determined using 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 the proceedings 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 proceedings, however, the Company does not believe, based on currently available information, that the outcomes 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 Hunter Labs Settlement Agreement, the Company recorded a litigation settlement expense of $34.5 in the second quarter of 2011 (net of a previously recorded reserve of $15.0) and paid the settlement amount of $49.5 in the third quarter of 2011. 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 2011, the California legislature enacted Assembly Bill No. 97, which imposed a 10.0% Medi-Cal payment cut on most providers of healthcare services, including clinical laboratories. This 10% cut is currently being applied to the rates that would otherwise be applicable. In 2012, the California legislature enacted Assembly Bill No. 1494, which directed the Department of Healthcare Services (DHCS) to establish new reimbursement rates for Medi-Cal commercial laboratory services based on payments made to California clinical laboratories for similar services by other third-party payers, and provided that until the new rates are set through this process, Medi-Cal payments for commercial laboratory services will be reduced (in addition to a 10.0% 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 80.0% of the lowest maximum allowance established under the 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 April 2015, CMS approved a 10.0% payment reduction under Assembly Bill No. 1494. The new rate methodology established new rates that were effective July 1, 2015, but these new rates were not entered into the state computer system until February 2016. Based on reported 2015 payment data, new rates were established to be effective July 1, 2016, but due to computer system delays, these rates have not been fully implemented yet and recoupments associated with these changes are anticipated, but have not begun. 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 U.S. Department of Health & Human Services Office of Inspector General's regional office in New York. On August 17, 2011, the United States District Court for 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 the False Claims Acts of 14 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 and Plaintiff was granted the right to repeal. On January 11, 2016, Plaintiff filed a motion requesting leave to file an amended complaint under seal and to vacate the briefing schedule for the Company's motion to dismiss while the government reviews the amended complaint. The Court granted the motion and vacated the briefing dates. Plaintiff then filed an amended complaint under seal. The Company will vigorously defend the lawsuit.

In addition, the Company has received various 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 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 lawsuit, 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. The Company’s Motion to Dismiss was denied in February 2015. In December 2016, the Court granted the Company’s Motion for Partial Summary Judgment. The Company will vigorously defend the remaining claims in 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 State of Georgia filed a Notice of Declination on August 13, 2012, before the Company was served with the Complaint. The case was 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. On March 14, 2014, the Company's Motion to Dismiss was granted. The Plaintiffs replied their complaint, and the Company filed a Motion to Dismiss the First Amended Complaint. In May 2015, the Court dismissed the Plaintiffs' anti-kickback claim and remanded the remaining state law claims to the State Court of Fulton County. In July 2015, the Company filed a Motion to Dismiss these remaining claims. The Plaintiffs filed an opposition to the Company's Motion to Dismiss in August 2015. Also, the State of Georgia filed a brief as amicus curiae. The Company will vigorously defend the lawsuit.

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. In June 2015, Plaintiff's Motion for Class Certification was denied. The Plaintiff appealed the denial of Class Certification, and the Court of Appeals affirmed the denial of the Motion for Class Certification on January 20, 2017. The Company will vigorously defend the lawsuit.

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 lawsuit alleges that on or about February 21, 2012, the defendants violated the U.S. Telephone Consumer Protection Act (TCPA) by sending unsolicited facsimiles to Plaintiff and more than 39 other recipients without the recipients' prior express invitation or permission. 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 filed a notice of appeal. On May 3, 2016, the United States Court of Appeals for the Eighth Circuit issued its decision and order reversing the District Court's denial of class certification. The Eighth Circuit remanded the matter for further proceedings. On December 7, 2016, the District Court granted the Plaintiff's renewed Motion for Class Certification. The Company will vigorously defend the lawsuit.

On August 31, 2015, the Company was served with a putative class action lawsuit, Patty Davis v. Laboratory Corporation of America, et al., filed in the Circuit Court of the Thirteenth Judicial Circuit for Hillsborough County, Florida. The complaint alleges that the Company violated the Florida Consumer Collection Practices Act by billing patients who were collecting benefits under the Workers' Compensation Statutes. The lawsuit seeks injunctive relief and actual and statutory damages, as well as recovery of attorney's fees and legal expenses. On December 28, 2016, the Company filed a Motion for Judgment on the Pleadings. The Company will vigorously defend the lawsuit.

In December 2014, the Company received a Civil Investigative Demand issued pursuant to the U.S. 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.

On August 3, 2016, the Company was served with a putative class action lawsuit, Daniel L. Bloomquist v. Covance Inc., et al., filed in the Superior Court of California, County of San Diego. The complaint alleges that Covance, Inc. violated the California Labor Code and California Business & Professions Code by failing to provide overtime wages, failing to provide meal and rest periods, failing to pay for all hours worked, failing to pay for all wages owed upon termination, and failing to provide accurate itemized wage statements to Clinical Research Associates and Senior Clinical Research Associates employed by Covance, Inc. in California. The lawsuit seeks monetary damages, civil penalties, injunctive relief, and recovery of attorney's fees and costs. On October 13, 2016, the case was removed to the United States District Court for the Southern District of California. The Company will vigorously defend the lawsuit.



Prior to the Company’s acquisition of Sequenom, between August 15, 2016 and August 24, 2016, six putative class-action lawsuits were filed on behalf of purported Sequenom stockholders (captioned Malkoff v. Sequenom, Inc., et al., No. 16-cv-02054-JAH-BLM, Gupta v. Sequenom, Inc., et al., No. 16-cv-02084-JAH-KSC, Fruchter v. Sequenom, Inc., et al., No. 16-cv-02101-WQH-KSC, Asiatrade Development Ltd. v. Sequenom, Inc., et al., No. 16-cv-02113-AJB-JMA, Nunes v. Sequenom, Inc., et al., No. 16-cv-02128-AJB-MDD, and Cusumano v. Sequenom, Inc., et al., No. 16-cv-02134-LAB-JMA) in the United States District Court for the Southern District of California challenging the acquisition transaction. The complaints asserted claims against Sequenom and members of its Board of Directors (the Individual Defendants). The Nunes action also named the Company and Savoy Acquisition Corp. (Savoy), a wholly owned subsidiary of the Company, as defendants. The complaints alleged that the defendants violated Sections 14(e), 14(d)(4) and 20 of the Securities Exchange Act of 1934 by failing to disclose certain allegedly material information. In addition, the complaints in the Malkoff action, Asiatrade action, and the Cusumano action alleged that the Individual Defendants breached their fiduciary duties to Sequenom shareholders. The actions sought, among other things, injunctive relief enjoining the merger. On August 30, 2016, the parties entered into a Memorandum of Understanding (MOU) in each of the above-referenced actions. In connection with the settlement, Sequenom agreed to make certain additional disclosures to its stockholders. On September 6, 2016, the Court entered an order consolidating for all pre-trial purposes the six individual actions described above under the caption In re Sequenom, Inc. Shareholder Litig., Lead Case No. 16-cv-02054-JAH-BLM, and designating the complaint from the Malkoff action as the operative complaint for the consolidated action. On November 11, 2016, two competing motions were filed by two separate stockholders (James Reilly and Shikha Gupta) seeking appointment as lead plaintiff under the terms of the Private Securities Litigation Reform Act of 1995. On January 12, 2017 the Court entered an order declaring Mr. Reilly the presumptive lead plaintiff, but denying Mr. Reilly's request for immediate approval as lead plaintiff. The Company is awaiting the Court's appointment of a permanent lead plaintiff. The parties agree that the MOU has been terminated and are awaiting further direction from the Court as to how the litigation will proceed.

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, 2016, the Company had provided letters of credit aggregating approximately $54.5, 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 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 Cellmark Forensics, Inc. (formerly Orchid Cellmark, Inc.) and the Integrated Genetics business (formerly Genzyme Genetics) and costs associated with the 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. In addition, the Company recorded $6.2 in accelerated amortization relating to the termination of a licensing agreement.

(f) During the first quarter of 2016, the Company adopted Accounting Standards Update (ASU) 2015-03, Interest-Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs.

Long-term obligations exclude amounts due to affiliates.

(h) During 2016, the Company revised the final purchase price allocation for Covance Inc. As a result, an out of period adjustment of $25.6 was recorded to reduce goodwill and increase a deferred tax asset as of December 31, 2015. The Company concluded that the impact of this adjustment was not material to the current or prior periods.

(i) The Company changed its financial statement classification for certain gross receipts taxes in 2016, removing these taxes from its provision for income taxes and moving this expense into selling, general and administrative expenses.

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

## General

Net revenues increased 11.0% in comparison to 2015 primarily due to the inclusion of Covance's financial results for the entire year as well as solid organic growth and acquisitions, partially offset by the negative impact of foreign currency translation.

The Company completed several acquisitions in the fourth quarter of 2016. The Company expects these acquisitions along with the acquisitions that were announced in 2017, prior to the filing of this Form 10-K, to increase net revenues by less than 2%, with a comparable increase in operating income.

The Company remains on pace to achieve annual cost synergies in excess of $100.0 by December 31, 2017. The Company also resumed its share repurchase program in the fourth quarter of 2016. The Company is committed to maintaining its investment grade credit rating and plans to use its operating cash flows to meet its annual capital expenditure requirements and to continue building long-term shareholder value through strategic acquisitions, debt reduction and the return of capital to shareholders.

The Company notes that changes to, or repeal of, the Affordable Care Act may continue to affect coverage, reimbursement and utilization of laboratory services, as well as administrative requirements, in ways that are currently unpredictable. Further, structural reforms of Medicare that could occur under the 115th Congress and the new administration, such as imposition of uniform co-insurance and combination of the Medicare Part A and Part B deductibles, could adversely affect laboratory reimbursement under Medicare.

The Company has seen increases in the amount of its patient accounts receivable. A significant portion of the Company’s bad debt expense is related to LabCorp Diagnostics segment 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.

Prior to the first quarter of 2015, the chief operating decision maker (CODM) managed the operating results of the Company as two segments: commercial laboratory diagnostics and other. In connection with the Acquisition, the Company changed its operating segments to align with how the CODM evaluates financial information used to allocate resources and assess performance of the Company following the Acquisition. The segment information presented in the Company's consolidated financial statements has been conformed to present segments on this revised basis for all prior periods. Under the new organizational structure, the CODM manages the Company under two reportable segments: LabCorp Diagnostics (LCD) and Covance Drug Development (CDD). LCD includes the Company's legacy LabCorp business, and the Company's nutritional chemistry and food safety business, which was previously part of Covance, but excludes LabCorp's legacy clinical trials testing business, which is now part of CDD. CDD includes the Covance legacy business, and LabCorp's legacy clinical trials testing business, but excludes the Company's nutritional chemistry and food safety business, which is now part of LCD.

## Seasonality and External Factors

The Company experiences seasonality in both segments of its business. For example, testing volume generally declines during the year-end holiday period and other major holidays and can also decline due to inclement weather, reducing net revenues, operating margins and cash flows. Operations are also impacted by changes in the global economy, exchange rate fluctuations, political and regulatory changes, the progress of ongoing studies and the startup of new studies, as well as the level of expenditures made by the biopharmaceutical industry in R&D. The results of both segments are impacted by exchange rate fluctuations. Given the seasonality of the business, comparison of the results for successive quarters may not accurately reflect trends or results for the full year.

The increase in net revenues for the year ended December 31, 2016 was driven primarily by the inclusion of Covance's financial results for the entire year as well as solid organic growth and acquisitions, partially offset by the negative impact of foreign currency translation.

LCD net revenues for the year ended December 31, 2016 were $6,593.9, an increase of 6.4% over net revenues of $6,199.3 in the corresponding period in 2015. The increase in net revenues was driven by organic volume growth, measured by requisitions, of 1.2%. Beacon LBS, the Company's technology-enabled solution providing point-of-care decision support, contributed 0.3%. The increase in net revenues was unfavorably impacted by 0.3% of currency fluctuations. Revenue per requisition favorably impacted revenue by 2.7%. In addition, acquisitions added 2.5% to net revenues.

CDD net revenues for the year ended December 31, 2016 were $2,844.1, an increase of 23.3% over net revenues of $2,306.4 in the corresponding period in 2015. The increase in revenue is due to the inclusion of a full year of Covance revenue for 2016 as compared to the period from the close of the Acquisition on February 19, 2015 through December 31, 2015, as well as demand and mix. This increase was partially offset by the expiration on October 31, 2015 of a minimum volume service contract and an unfavorable currency impact of approximately 160 basis points. Approximately 50.9% of CDD's net revenues are billed in currencies other than the U.S. dollar, with the Swiss franc, British pound, and the Euro representing approximately 32.3% of CDD's total currency exposure.

The increase in net revenues for the year ended December 31, 2015 was driven primarily by the Acquisition along with strong organic volume growth in LCD and tuck-in acquisitions, price, and mix, partially offset by currency.

LCD net revenues for the year ended December 31, 2015 were $6,199.3, an increase of 6.2% over net revenues of $5,838.0 in the corresponding period in 2014. The increase in net revenues was driven by organic volume growth, measured by requisitions, of 3.2%. Beacon LBS contributed 0.9%. The increase in net revenues was unfavorably impacted by 0.8% of currency. Revenue per requisition favorably impacted revenue by 0.4%. In addition, acquisitions added 2.5% to net revenues.

CDD net revenues for the year ended December 31, 2015 were $2,306.4, an increase of 1,228.6% over net revenues of $173.6 in the corresponding period in 2014. The increase in net revenues was due to the Acquisition. Approximately 52.1% of CDD's net revenues are billed in currencies other than the U.S. dollar, with the Swiss franc, British pound, and the Euro representing approximately 66.8% of CDD's total currency exposure. The 2014 CDD net revenue amount represents LabCorp's legacy clinical trials testing business.

## Net Cost of Revenues

<table><tr><td rowspan="2"></td><td colspan="3">Years Ended December 31,</td><td colspan="2">Change</td></tr><tr><td>2016</td><td>2015</td><td>2014</td><td>2016</td><td>2015</td></tr><tr><td>Net cost of revenues</td><td>$ 6,256.7</td><td>$ 5,602.4</td><td>$ 3,808.5</td><td>11.7%</td><td>47.1%</td></tr><tr><td>Cost of revenues as a % of net revenues</td><td>66.3%</td><td>65.9%</td><td>63.4%</td><td></td><td></td></tr></table>

Net cost of revenues (primarily laboratory, labor and distribution costs) increased 11.7% in 2016 as compared with 2015 primarily due to increased volume, measured by requisitions, and test mix changes. The increase in net cost of revenues as a percentage of net revenues in 2016 as compared to 2015 was due to the inclusion of CDD operations, which carry higher personnel costs as a percentage of revenue, for the entire year along with overall growth in the Company's operations. The increase in net cost of revenues in 2016 was negatively impacted by a net increase of 0.6% due to currency fluctuations.

Labor and testing supplies for the year ended December 31, 2016 comprise over 75.4% of the Company’s net cost of revenues. Net cost of revenues has increased over the three-year period ended December 31, 2016 primarily due to the impact of acquisitions, overall growth in the Company’s volume and increases in labor costs.

Net cost of revenues (primarily laboratory and distribution costs) increased 47.1% in 2015 as compared with 2014 primarily due to the Acquisition. Excluding acquisitions, net cost of revenues increased approximately 4.2% due to increased volume, measured by requisitions, and test mix changes. The increase in net cost of revenues in 2015 was favorably impacted by a net reduction of 0.8% due to currency fluctuations. Labor and testing supplies for the year ended December 31, 2015, comprise over 75.5% of the Company’s net cost of revenues.

## 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>2016</td><td>2015</td><td>2014</td><td>2016</td><td>2015</td></tr><tr><td>Selling, general and administrative expenses</td><td>$ 1,630.2</td><td>$ 1,628.1</td><td>$ 1,204.3</td><td>0.1%</td><td>35.2%</td></tr><tr><td>SG&amp;A as a % of net revenues</td><td>17.3%</td><td>19.1%</td><td>20.0%</td><td></td><td></td></tr></table>

Selling, general and administrative expenses as a percentage of net revenues decreased to 17.3% in 2016 compared to 19.1% in 2015. The decrease in selling, general and administrative expenses as a percentage of net revenues is primarily due to the



Acquisition, integration synergies, and the impact of LaunchPad, LCD's comprehensive, enterprise-wide business process improvement initiative. Bad debt expense as a percentage of net revenues for LCD remained constant at 4.3% for that segment during 2016 and 2015. The increase in selling, general and administrative expenses in 2016 was impacted by a net increase of 0.5% due to currency fluctuations.

During 2016, the Company incurred additional legal and other costs of $4.6 relating to the wind-down of two operations used to service minimum volume service contract operations. On February 9, 2016, the Company reached an agreement for the sale of assets and business of one of these sites. As required by U.K. law, substantially all of the employees were transferred with the business. On November 21, 2016, following the wind-down of the business, the Company reached an agreement for the sale of the property and assets of the other site. In addition, the Company incurred $8.0 in acquisition fees and expenses. The Company also recorded $6.9 in consulting expenses relating to fees incurred as part of its Acquisition integration costs and compensation analysis, along with $2.5 in short-term equity retention arrangements relating to the Acquisition and $8.9 of accelerated equity compensation relating to executive transition (all recorded in selling, general and administrative expenses). In addition, the Company incurred $9.0 of non-capitalized costs associated with the implementation of a major system as part of LaunchPad.

Selling, general and administrative expenses as a percentage of net revenues decreased to 19.1% in 2015 compared to 20.0% in 2014. The decrease in selling, general and administrative expenses as a percentage of net revenues is primarily due to the Acquisition and the impact of LaunchPad and integration synergies. In addition, bad debt expense as a percentage of net revenues for LCD decreased to 4.3% of net revenues for that segment compared to 4.6% during 2014. This improvement in LCD's bad debt expense is a result of the segment's focus on improved cash collections and other related LaunchPad initiatives. As discussed in Restructuring and Other Special Charges, the Company incurred $164.5 in fees and expenses in 2015. The increase in selling, general and administrative expenses in 2015 was impacted by a net reduction of 0.8% due to currency fluctuations.

During 2015, the Company incurred additional legal and other costs of $5.7 relating to the wind-down of two operations used to service minimum volume contract operations. The Company also recorded $25.6 in consulting expenses relating to fees incurred as part of LaunchPad as well as Covance integration costs and employee compensation studies, along with $5.4 in short-term equity retention arrangements relating to the acquisition of Covance and $0.3 of accelerated equity compensation relating to the previously disclosed retirement of a Company executive (all recorded in selling, general and administrative expenses). During the fourth quarter, the Company paid $12.2 in settlement costs and litigation expenses related to the resolution of a U.S. federal court putative class action lawsuit. In addition, the Company incurred $3.0 of non-capitalized costs associated with the implementation of a major system as part of LaunchPad.

During 2014, the Company recorded $18.6 in consulting expenses relating to fees incurred as part of its business process improvement initiative as well as 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.

## Amortization Expense

<table><tr><td rowspan="2"></td><td colspan="4">Years Ended December 31,</td><td colspan="2">Change</td></tr><tr><td>2016</td><td>2015</td><td>2014</td><td>2016</td><td>2015</td><td></td></tr><tr><td>LCD</td><td>$ 93.4</td><td>$ 82.4</td><td>$ 75.5</td><td>13.3%</td><td>9.1%</td><td></td></tr><tr><td>CDD</td><td>86.1</td><td>82.1</td><td>1.2</td><td>4.9%</td><td>6,741.7%</td><td></td></tr><tr><td>Amortization of intangibles and other assets</td><td>$ 179.5</td><td>$ 164.5</td><td>$ 76.7</td><td>9.1%</td><td>114.5%</td><td></td></tr></table>

The increase in amortization of intangibles and other assets from 2014-2016 primarily reflects the impact of the Acquisition and tuck-in acquisitions offset by the impact of working capital and earnout adjustments. The increase in amortization for CDD in 2016 is due to currency fluctuations and the inclusion of their results for a full twelve months in 2016.

## Restructuring and Other Special Charges

<table><tr><td rowspan="2"></td><td colspan="4">Years Ended December 31,</td></tr><tr><td>2016</td><td>2015</td><td>2014</td><td></td></tr><tr><td>Restructuring and other special charges</td><td>$ 58.4</td><td>$ 113.9</td><td>$ 17.8</td><td></td></tr></table>

During 2016, the Company recorded net restructuring and other special charges of $58.4; $15.8 within LCD and $42.6 within CDD. The charges were comprised of $30.9 related to severance and other personnel costs along with $33.8 in costs associated with facility closures. A substantial portion of these costs relate to the planned closure of duplicative data center operations and other facilities. These charges were offset by the reversal of previously established reserves of $2.8 in unused severance and $3.5 in unused facility-related costs, as the result of selling one of its minimum volume service contract facilities to a third party.

During 2015, the Company recorded net restructuring and other special charges of $113.9; $39.2 within LCD and $74.7 within CDD. The charges were comprised of $59.2 related to severance and other personnel costs along with $55.8 in costs associated with facility closures and general integration initiatives. A substantial portion of these costs relate to the planned closure of two



CDD operations that serviced a minimum volume contract that expired on October 31, 2015. These charges were offset by the reversal of previously established reserves of $1.1 in unused facility-related costs. Included within the facility-related charges noted above is a $26.7 asset impairment charge relating to CDD lab and customer service applications that will no longer be used.

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.

## Interest Expense

<table><tr><td rowspan="2"></td><td colspan="4">Years Ended December 31,</td><td colspan="2">Change</td></tr><tr><td>2016</td><td>2015</td><td>2014</td><td>2016</td><td>2015</td><td></td></tr><tr><td>Interest expense</td><td>$ 219.1</td><td>$ 274.9</td><td>$ 109.5</td><td>(20.3)%</td><td>151.1%</td><td></td></tr></table>

The decrease in interest expense for 2016 as compared with the corresponding period in 2015 is primarily due to the reduction of the term loan balance, Acquisition-related expenses including a $37.4 make-whole payment that was required in connection with the prepayment of the $250.0 Covance senior notes and $15.2 of deferred financing costs associated with the Company's previous credit agreement and the bridge financing facilities used to complete the Acquisition. In addition, the Company repaid the 3.125% Senior Notes in May 2016. These decreases were offset by $5.6 of interest expense relating to the early retirement of subsidiary indebtedness and the timing of Acquisition-related debt.

The increase in interest expense for 2015 as compared with 2014 was primarily due to the issuance of $3,900 in debt and other financing costs in connection with the Acquisition. Another component of the increase was the $37.4 make-whole payment in connection with the prepayment of Covance senior notes and the $15.2 relating to the deferred financing cost associated with the Company's previous credit agreement and the bridge financing facility. The bridge facility was repaid in March 2015.

## Equity Method Income, Net

<table><tr><td rowspan="2"></td><td colspan="4">Years Ended December 31,</td><td colspan="2">Change</td></tr><tr><td>2016</td><td>2015</td><td>2014</td><td>2016</td><td>2015</td><td></td></tr><tr><td>Equity method income, net</td><td>$ 7.9</td><td>$ 10.0</td><td>$ 14.3</td><td>(21.0)%</td><td>(30.1)%</td><td></td></tr></table>

Equity method income, net represents the Company's ownership share in joint venture partnerships along with equity investments in other companies in the healthcare industry. All of these partnerships reside within LCD. The decrease in income in 2016 and 2015 was primarily due to liquidation of the Company's interest in one of the partnerships effective June 30, 2015.

## Other, net

<table><tr><td rowspan="2"></td><td colspan="4">Years Ended December 31,</td><td colspan="2">Change</td></tr><tr><td>2016</td><td>2015</td><td>2014</td><td>2016</td><td>2015</td><td></td></tr><tr><td>Other, net</td><td>$ 2.6</td><td>$ (7.8)</td><td>$ 10.4</td><td>133.3%</td><td>(175.0)%</td><td></td></tr></table>

The increase in other, net for the year ended December 31, 2016, is primarily due to a net gain of $9.7 on the sale of investment securities from the Company's venture fund offset by net realized foreign currency translation losses and a non-cash loss of $2.3 upon the dissolution of one of the Company's equity investments in 2015.

The decrease in other, net for the year ended December 31, 2015 was due to the dissolution of one of the Company's equity investments as compared to a gain on the sale of investment of an equity investment of $14.7 in 2014.

## Income Tax Expense

<table><tr><td rowspan="2"></td><td colspan="4">Years Ended December 31,</td></tr><tr><td>2016</td><td>2015</td><td>2014</td><td></td></tr><tr><td>Income tax expense</td><td>$ 372.3</td><td>$ 287.3</td><td>$ 308.0</td><td></td></tr><tr><td>Income tax expense as a % of income before tax</td><td>33.7%</td><td>39.6%</td><td>37.5%</td><td></td></tr></table>

In 2016 and 2015, the Company's effective rate was favorably impacted by foreign earnings taxed at lower rates than the U.S. statutory tax rate and, for 2016 specifically, by a reduction in certain foreign rates. The 2016 rate also benefited from the early adoption of share-based payment accounting and the reversal of uncertain tax position reserves. The Company considers substantially all of its foreign earnings to be permanently reinvested overseas.

The effective rate for 2015 was unfavorably impacted by restructuring and acquisition items, the recording of additional uncertain tax reserves and a decrease in the benefit recorded from releasing uncertain tax reserves.



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.

## 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. The Company's senior unsecured revolving credit facility is further discussed in Note 11 (Debt) to the Company's Consolidated Financial Statements.

In summary the Company's cash flows were as follows:

Cash and cash equivalents at December 31, 2016, 2015 and 2014 totaled $433.6, $716.4, and $580.0, respectively. Cash and cash equivalents consist of highly liquid instruments, such as commercial paper, time deposits and other money market investments, substantially all of which have original maturities of three months or less.

## Cash Flows From Operating Activities

During the year ended December 31, 2016, the Company's operations provided $1,175.9 of cash as compared to $982.4 in 2015. The $193.5 increase in cash provided from operations in 2016 as compared with the corresponding 2015 period was primarily due to higher net earnings in 2016. The Company's 2016 earnings were impacted by $58.4 of restructuring and special items compared to an impact of $113.9 during the same period in 2015, primarily in connection with the Acquisition.

Net cash provided by operating activities for the year ended December 31, 2015 was $982.4 compared to $739.0 for the year ended December 31, 2014. The $243.4 increase in cash provided by operations was due primarily to additional cash generated by CDD operations following the Acquisition, as well as improved working capital. While there were lower net earnings due to the Acquisition, this included a number of non-cash charges. The Company's earnings were impacted by restructuring and special items of $113.9 during 2015, compared to an impact of $17.8 during the same period in 2014. During 2015, the Company's operating cash flows were reduced by $153.5 of cash payments in connection with the Acquisition.

## Cash Flows From Investing Activities

Net cash used in investing activities for the year ended December 31, 2016 was $795.7 as compared to $3,994.9 for the year ended December 31, 2015. The $3,184.3 decrease in cash used in investing activities for the year ended December 31, 2016 was primarily due to cash paid for the Acquisition in the first quarter of 2015. In addition, the Company had proceeds of $30.8 from the sale of assets during 2016 in comparison to $0.6 during 2015. Capital expenditures were $278.9 and $255.8 for the years ended December 31, 2016 and 2015, respectively. Capital expenditures in 2016 were 3.0% of net revenues primarily in connection with projects to support growth in the Company's core businesses, projects related to LaunchPad and further Covance integration initiatives. The Company intends to continue to pursue acquisitions to fund growth and make important investments in its business, including in information technology, and to improve efficiency and enable the execution of the Company's mission. Such expenditures are expected to be funded by cash flow from operations or, as needed, through borrowings under debt facilities, including the Company's revolving credit facility or any successor facility.

Net cash used in investing activities for the year ended December 31, 2015 was $3,994.9 as compared to $350.1 for the year ended December 31, 2014. The $199.2 increase in cash used in investing activities was primarily due to net cash paid for the Acquisition of $3,607.4, ($4,388.2 cash paid, net of cash acquired of $780.8). Capital expenditures were $255.8 and $203.5 for the years ended December 31, 2015 and 2014, respectively.

## Cash Flows From Financing Activities

Net cash used in financing activities for the year ended December 31, 2016 was $649.8 compared to $3,184.6 net cash provided by financing activities for the year ended December 31, 2015. This movement in cash within financing activities for 2016, as compared to 2015, was primarily a result of $3,113.7 of net financing proceeds in 2015 compared to $658.4 in debt repayments combined with $43.9 for the re-initiation of the Company's share repurchase program in 2016.



Net cash provided by financing activities for the year ended December 31, 2015 was $3,184.6 compared to $200.6 net cash used in financing activities for the year ended December 31, 2014. The $3,385.2 increase in the cash provided by financing activities for 2015, as compared to the prior year, was primarily a result of $4,360.0 of financing proceeds for the Acquisition offset by debt repayments and debt issue costs of $781.7. The Company also repaid $500.0 of senior notes (including $250.0 of Covance senior notes) in 2015. The remainder of the period-over-period increase was primarily due to the suspension of share repurchases following the Acquisition, compared to $269.0 share repurchases for 2014.

On December 19, 2014, the Company entered into a five-year term loan 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 Acquisition. The term loan facility may be prepaid without penalty. The term loan balance was $565.0 and $715.0 at December 31, 2016 and 2015, respectively.

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 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 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.

Also as part of its financing of the Acquisition, 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.

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 Acquisition. The 60-day cash bridge term loan credit facility was advanced in full on the Acquisition Date, and was repaid in March 2015.

Under its term loan credit facility and its revolving credit facility, 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 variable leverage ratio. From and after the Acquisition Date, the leverage ratio was required to 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 under the credit facilities at December 31, 2016 and 2015. As of December 31, 2016, the ratio of total debt to consolidated EBITDA was 3.1 to 1.0.

The term loan credit facility accrues 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 revolving credit facility 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 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 revolving credit facility, at a per annum rate ranging from 0.125% to 0.40%. The interest margin applicable to the credit facilities, and the facility fee and letter of credit fees payable under the 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.

As of December 31, 2016, the effective interest rate on the revolving credit facility was 1.9% and the effective interest rate on the term loan was 2.0%.

There was no outstanding balance on the Company's revolving credit facility at December 31, 2016 or 2015. As of December 31, 2016, the Company provided letters of credit aggregating $54.5, primarily in connection with certain insurance programs. Letters of credit provided by the Company are issued under the Company's revolving credit facility and are renewed annually.

The Company resumed its share repurchase program in the fourth quarter of 2016, repurchasing 0.3 shares for $43.9, based on settled trades as of December 31, 2016, at an average price of approximately $128.00. The Company also initiated purchases of $6.1 which settled directly after December 31, 2016. At the end of 2016, including unsettled purchase commitments, $739.5 of repurchase authorization remained under the Company's share repurchase program.



The Company had a $28.3 and $36.9 reserve for unrecognized income tax benefits, including interest and penalties as of December 31, 2016 and December 31, 2015, respectively. Substantially all of these tax reserves are classified in other long-term liabilities in the Company's Consolidated Balance Sheets at December 31, 2016 and 2015.

During 2016 and 2015, the Company settled notices to convert $59.4 and $1.5 aggregate principal amount at maturity of its zero-coupon subordinated notes with a conversion value of $53.7 and $1.3, respectively. The total cash used for these settlements was $53.7 and $1.3 and the Company also issued 0.4 and 0.0 additional shares of common stock, respectively. As a result of these conversions in 2016 and 2015, the Company also reversed approximately $4.9 and $0.4, respectively, of deferred tax liability to reflect the tax benefit realized upon issuance of the shares.

On September 12, 2016, the Company announced that for the period of September 12, 2016 to March 10, 2017, 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, 2016, in addition to the continued accrual of the original issue discount.

On January 3, 2017, 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, 2017, 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 Friday, March 31, 2017. 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 revolving credit facility.

## Credit Ratings

The Company’s debt ratings of Baa2 from Moody’s and BBB from S&P 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 the achievement specified revenue milestones.

(b) 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.

(c) The table does not include the Company’s reserves for unrecognized tax benefits. The Company had a $28.3 and $36.9 reserve for unrecognized tax benefits, including interest and penalties, at December 31, 2016 and 2015, 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, 2016 and 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 credit.



## Other Commercial Commitments

As of December 31, 2016, the Company provided letters of credit aggregating approximately $54.5, primarily in connection with certain insurance programs. Letters of credit provided by the Company are secured by the Company’s revolving credit facility and are renewed annually.

The contractual value of the noncontrolling interest put in the Company's Ontario subsidiary totaled $15.2 and $14.9 at December 31, 2016 and 2015, respectively, and has been classified as mezzanine equity in the Company's consolidated balance sheet.

Based on current and projected levels of cash flows from 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.

## 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

LCD recognizes revenue for services rendered when the testing process is complete and test results are reported to the ordering physician. The sales are generally billed to three types of payers – customers, patients and third parties such as MCOs, Medicare and Medicaid. For customers, sales are recorded on a fee-for-service basis at the Company’s customer 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. LCD 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 MCOs, 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 the tests performed.

CDD recognizes revenue either as services are performed or products are delivered, depending on the nature of the work contracted. Historically, a majority of CDD’s net revenues have been earned under contracts that range in duration from a few months to a few years, but can extend in duration up to five years or longer. Occasionally, CDD also has committed minimum volume arrangements with certain customers. Under these types of arrangements, if the annual minimum dollar value of service commitment is not reached, the customer is required to pay CDD for the shortfall. Annual minimum commitment shortfalls are not included in net revenues until the amount has been determined and agreed to by the customer.

Service contracts generally take the form of fee-for-service or fixed-price arrangements subject to pricing adjustments based on changes in scope. In cases where performance spans multiple accounting periods, revenue is recognized as services are performed, measured on a proportional-performance basis, generally using output measures that are specific to the service provided. Examples of output measures in preclinical services include, among others, the number of slides read, or specimens prepared. Examples of output measures in the clinical trials services include, among others, the number of investigators enrolled, the number of sites initiated, the number of trial subjects enrolled and the number of monitoring visits completed, or the number of dosings for clinical pharmacology. Revenue is determined by dividing the actual units of work completed by the total units of work required under the contract and multiplying that percentage by the total contract value. The total contract value, or total contractual payments, represents the aggregate contracted price for each of the agreed upon services to be provided. CDD does not have any contractual



arrangements spanning multiple accounting periods where revenue is recognized on a proportional-performance basis under which the Company has earned more than an immaterial amount of performance-based revenue (i.e., potential additional revenue tied to specific deliverables or performance). Changes in the scope of work are common, especially under long-term contracts, and generally result in a change in contract value. Once the customer has agreed to the changes in scope and renegotiated pricing terms, the contract value is amended with revenue recognized as described above. Estimates of costs to complete are made to provide, where appropriate, for losses expected on contracts. Costs are not deferred in anticipation of contracts being awarded, but instead are expensed as incurred.

Billing schedules and payment terms are generally negotiated on a contract-by-contract basis. In some cases, CDD bills the customer for the total contract value in progress-based installments as certain non-contingent billing milestones are reached over the contract duration, such as, but not limited to, contract signing, initial dosing, investigator site initiation, patient enrollment or database lock. The term “billing milestone” relates only to a billing trigger in a contract whereby amounts become billable and payable in accordance with a negotiated predetermined billing schedule throughout the term of a project. These billing milestones are generally not performance-based (i.e., there is no potential additional consideration tied to specific deliverables or performance). In other cases, billing and payment terms are tied to the passage of time (e.g., monthly billings). In either case, the total contract value and aggregate amounts billed to the customer would be the same at the end of the project. While CDD attempts to negotiate terms that provide for billing and payment of services prior or within close proximity to the provision of services, this is not always possible, and there are fluctuations in the levels of unbilled services and unearned revenue from period to period. While a project is ongoing, cash payments are not necessarily representative of aggregate revenue earned at any particular point in time, as revenues are recognized when services are provided, while amounts billed and paid are in accordance with the negotiated billing and payment terms.

In some cases, payments received are in excess of revenue recognized. For example, a contract invoicing schedule may provide for an upfront payment of 10% of the full contract value upon contract signing, but at the time of signing performance of services has not yet begun. Payments received in advance of services being provided are deferred as unearned revenue on the balance sheet. As the contracted services are subsequently performed and the associated revenue is recognized, the unearned revenue balance is reduced by the amount of revenue recognized during the period.

In other cases, services may be provided and revenue recognized before the customer is invoiced. In these cases, revenue recognized will exceed amounts billed, and the difference, representing an unbilled receivable, is recorded for the amount that is currently not billable to the customer pursuant to contractual terms. Once the customer is invoiced, the unbilled services are reduced for the amount billed, and a corresponding account receivable is recorded. All unbilled services are billable to customers within one year from the respective balance sheet date.

Most contracts are terminable with or without cause by the customer, either immediately or upon notice. These contracts often require payment to CDD of expenses to wind down the study or project, fees earned to date and, in some cases, a termination fee or a payment to CDD of some portion of the fees or profits that could have been earned by CDD under the contract if it had not been terminated early. Termination fees are included in net revenues when realization is assured. In connection with the management of multi-site clinical trials, CDD pays on behalf of its customers fees to investigators, clinical trial subjects and certain out-of-pocket costs, for which it is reimbursed at cost, without mark-up or profit. Investigator fees are not reflected in net revenues or expenses where CDD acts in the capacity of an agent on behalf of the biopharmaceutical company sponsor, passing through these costs without markup or profit. All other out-of-pocket costs are included in total revenues and expenses.

LCD 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. LCD’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 LCD’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 LCD’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 LCD’s net accounts receivable outstanding by aging category at December 31, 2016 and 2015:



<table><tr><td>Days Outstanding</td><td>2016</td><td>2015</td></tr><tr><td>0 - 30</td><td>49.1%</td><td>46.8%</td></tr><tr><td>31 - 60</td><td>17.3%</td><td>16.9%</td></tr><tr><td>61 - 90</td><td>9.2%</td><td>12.1%</td></tr><tr><td>91 - 120</td><td>7.5%</td><td>7.4%</td></tr><tr><td>121 - 150</td><td>4.2%</td><td>4.4%</td></tr><tr><td>151 - 180</td><td>3.9%</td><td>4.1%</td></tr><tr><td>181 - 270</td><td>7.4%</td><td>7.1%</td></tr><tr><td>271 - 360</td><td>1.3%</td><td>1.1%</td></tr><tr><td>Over 360</td><td>0.1%</td><td>0.1%</td></tr></table>

The above table excludes the percentage of net accounts receivable outstanding by aging category for certain foreign operations, BeaconLBS, and the nutritional chemistry and food safety businesses. Combined these net accounts receivable balances comprise less than 11.1% of LCD's total net accounts receivable balances. The Company believes that including the aging of the accounts receivable for these businesses would not be representative of the majority of accounts receivable by aging category for LCD. The majority of the accounts receivable for the foreign operations, BeaconLBS, and the nutritional chemistry and food safety business are generally paid within 30 to 60 days of billing.

CDD endeavors to assess and monitor the creditworthiness of its customers to which it grants credit terms in the ordinary course of business. CDD maintains a provision for doubtful accounts relating to amounts due that may not be collected. This bad debt provision is monitored on a monthly basis and adjusted as circumstances warrant. Since the recorded bad debt provision is based upon management's judgment, actual bad debt write-offs may be greater or less than the amount recorded. Historically, bad debt write-offs have not been material. The allowance for doubtful accounts amounted to $2.8 and $3.4 at December 31, 2016 and 2015, respectively.

## Pension Expense

The Company has a defined benefit retirement plan (Company Plan) and a non-qualified supplemental retirement plan (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 (401K Plan) receive a minimum 3% non-electric 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 employed by the Company 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.

In addition, as a result of the Acquisition, the Company has a frozen non-qualified Supplemental Executive Retirement Plan (SERP). The SERP, which is not funded, is intended to provide retirement benefits for certain employees who were executive officers of Covance prior to the Acquisition. Benefit amounts are based upon years of service and compensation of the participating employees. As a result of the Acquisition, the Company also sponsors two defined benefit pension plans for the benefit of its employees at two U.K. subsidiaries (U.K. Plans) and one defined benefit pension plan for the benefit of its employees at a German subsidiary (German Plan), all of which are legacy plans of previously acquired companies and are closed to new entrants. Benefit amounts for all three plans are based upon years of service and compensation. The German Plan is unfunded while the U.K. Plans are funded. The Company’s funding policy for the U.K. Plans has been to contribute annually amounts at least equal to the local statutory funding requirements.

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 4.1% discount rate and a 6.8% expected long-term rate of return on plan assets for the Company Plan, a 4.2% discount rate for the PEP, a 3.8% discount rate for the SERP, a 1.7% discount rate and a 2.0% expected salary increase for the German plan and a 2.7% discount rate and a 3.8% expected salary increase for the U.K. Plans as of December 31, 2016.



## 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 at which 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 2016 retirement plan expense of $1.7 for the Company Plan and PEP. A one percentage point decrease or increase in the discount rate would have resulted in a respective increase or decrease in 2016 retirement plan expense of $2.0 for the U.K. Plans.

## Return on Plan Assets

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 2016 pension expense of $2.4 for the Company Plan. A one percentage point increase or decrease in the expected return on plan assets would have resulted in a corresponding change in 2016 pension expense of $1.9 for the U.K. Plans.

Net pension cost for 2016 was $14.9 as compared with $12.0 in 2015 and $8.1 in 2014. The increase in pension expense was due to increases in the amount of net amortization and deferral as a result of lower discount rates. Pension expense for the Company Plan and the PEP is expected to increase to $15.3 in 2017 as a result of a lower assumed discount rate and changes in participant mortality tables. Pension expense for the SERP is expected to decrease to $0.3 in 2017 as the 2016 expense included settlement accounting charges due to a change in control benefit enhancement provided to one additional executive. Pension expense for the Germany Plan and the U.K. Plans is expected to increase to $2.7 in 2017 as a result of a lower assumed discount rate and changes in participant mortality tables.

Further information on the Company’s defined benefit retirement plans 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 based on 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 or whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Following the Acquisition, the Company changed the timing of its annual impairment testing to the beginning of the fourth quarter. In accordance with updates to the FASB's 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.

Step One of the goodwill impairment test includes the estimation of the fair value of each reporting unit as compared to the carrying value of the reporting unit. Reporting units are businesses with discrete financial information that is available and reviewed by management. The Company estimates the fair value of a reporting unit using both income-based and market-based valuation methods. The income-based approach is based on the reporting unit's forecasted future cash flows that are discounted to the present value using the reporting unit's weighted average cost of capital. For the market-based approach, the Company utilizes a number of factors such as publicly available information regarding the market capitalization of the Company as well as operating results, business plans, market multiples, and present value techniques. Based upon the range of estimated values developed from the income and market-based methods, the Company determines the estimated fair value for the reporting unit. If the estimated fair value of the reporting unit exceeds the carrying value, the goodwill is not impaired and no further review is required. However, if the estimated fair value is less than the carrying value, the Company performs the second step of the goodwill impairment test to measure the amount of the impairment, if any. The second step involves a hypothetical allocation of the estimated fair value of the reporting unit to its tangible and intangible assets (excluding goodwill) and liabilities as if the reporting unit were newly acquired, which results in an implied fair value of the goodwill. The amount of the impairment charge is the excess of the recorded goodwill, if any, over the implied fair value of the goodwill.

The income-based fair value methodology requires management's assumptions and judgments regarding economic conditions in the markets in which the Company operates and conditions in the capital markets, many of which are outside of management's control. At the reporting unit level, fair value estimation requires management's assumptions and judgments regarding the effects of overall economic conditions on the specific reporting unit, along with assessment of the reporting unit's strategies and forecasts of future cash flows. Forecasts of individual reporting unit cash flows involve management's estimates and assumptions regarding:

- Annual cash flows, on a debt-free basis, arising from future revenues and profitability, changes in working capital, capital spending and income taxes for at least a five-year forecast period.

- A terminal growth rate for years beyond the forecast period. The terminal growth rate is selected based on consideration of growth rates used in the forecast period, historical performance of the reporting unit and economic conditions.

- A discount rate that reflects the risks inherent in realizing the forecasted cash flows. A discount rate considers the risk-free rate of return on long-term treasury securities, the risk premium associated with investing in equity securities of comparable companies, the beta obtained from the comparable companies and the cost of debt for investment grade issuers. In addition, the discount rate may consider any company-specific risk in achieving the prospective financial information.

Under the market-based fair value methodology, judgment is required in evaluating market multiples and recent transactions. Management believes that the assumptions used for its impairment tests are representative of those that would be used by market participants performing similar valuations of the reporting units.

Management concluded that no triggering events occurred during 2016 related to goodwill and indefinite-lived intangible assets. As such, management performed its annual goodwill and intangible asset impairment testing as of the beginning of the fourth quarter of 2016. The Company elected to perform the qualitative assessment for goodwill and intangible assets for all reporting units except two of the CDD reporting units and the indefinite-lived Canadian licenses for which the quantitative assessment was used.

In the qualitative assessment, the Company considered relevant events and circumstances for each reporting unit, including (i) current year results, ii) financial performance versus management’s annual and five-year strategic plans, iii) changes in the reporting unit carrying value since prior year, (iv) industry and market conditions in which the reporting unit operates, (v) macroeconomic conditions, including discount rate changes, and (vi) changes in products or services offered by the reporting unit. If applicable, performance in recent years was compared to forecasts included in prior valuations. Based on the results of the



qualitative assessment, the Company concluded that it was not more likely than not that the carrying values of the goodwill and intangible assets were greater than their fair values, and that further quantitative testing was not necessary.

In 2016, the Company utilized an income approach to determine the fair value of two of the CDD reporting units, with $460.7 million and $223.9 million of goodwill as of September 30, 2016. Based upon the results of the quantitative assessment, the Company concluded that the fair value of these reporting units was greater than the carrying value.

In 2016, the Company also utilized an income approach to determine the fair value of its Canadian reporting unit and its indefinite-lived assets consisting of acquired Canadian licenses. Based upon the results of the quantitative assessment, the Company concluded that the fair value of the indefinite-lived Canadian licenses was greater than the carrying value.

It is possible that the Company's conclusions regarding impairment or recoverability of goodwill or intangible assets in any reporting unit could change in future periods. There can be no assurance that the estimates and assumptions used in the Company's goodwill and intangible asset impairment testing performed as of the beginning of the fourth quarter of 2016 will prove to be accurate predictions of the future, if, for example, (i) the businesses do not perform as projected, (ii) overall economic conditions in 2017 or future years vary from current assumptions (including changes in discount rates), (iii) business conditions or strategies for a specific reporting unit change from current assumptions, including loss of major customers, (iv) investors require higher rates of return on equity investments in the marketplace or (v) enterprise values of comparable publicly traded companies, or actual sales transactions of comparable companies, were to decline, resulting in lower multiples of revenues and EBITDA. The Company will particularly monitor the financial performance of and assumptions for two of the CDD reporting units for which an income approach was performed in 2016. A future impairment charge for goodwill or intangible assets could have a material effect on the Company's consolidated financial position and results of operations.

## Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK (in millions)

Market risk is the potential loss arising from adverse changes in market rates and prices, such as foreign currency exchange rates, interest rates and other relevant market rate or price changes. In the ordinary course of business, the Company is exposed to various market risks, including changes in foreign currency exchange and interest rates, and the Company regularly evaluates the exposure to such changes. The Company addresses its exposure to market risks, principally the market risks associated with changes in foreign currency exchange rates and interest rates, through a controlled program of risk management that includes, from time to time, the use of derivative financial instruments such as foreign currency forward contracts and 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.

## Foreign Currency Exchange Rates

Approximately 10.3% of the Company's net revenues for the year ended December 31, 2016 and approximately 11.0% of those for the year ended 2015 were denominated in currencies other than the U.S. Dollar. The Company's financial statements are reported in U.S. Dollars and, accordingly, fluctuations in exchange rates will affect the translation of revenues and expenses denominated in foreign currencies into U.S. Dollars for purposes of reporting the Company's consolidated financial results. In both 2016 and 2015, the most significant currency exchange rate exposures were to the Canadian Dollar, Swiss Franc, Euro and British Pound. Excluding the impacts from any outstanding or future hedging transactions, a hypothetical change of 10% in average exchange rates used to translate all foreign currencies to U.S. Dollars would have impacted income before income taxes for 2016 by approximately $6.1. Gross accumulated currency translation adjustments recorded as a separate component of shareholders' equity were $(250.0) and $(370.7) at December 31, 2016 and 2015, respectively. The Company does not have significant operations in countries in which the economy is considered to be highly inflationary.

The Company earns revenue from service contracts over a period of several months and, in some cases, over a period of several years. Accordingly, exchange rate fluctuations during this period may affect the Company's profitability with respect to such contracts. The Company is also subject to foreign currency transaction risk for fluctuations in exchange rates during the period of time between the consummation and cash settlement of transactions. The Company limits its foreign currency transaction risk through exchange rate fluctuation provisions stated in some of its contracts with customers, or it may hedge transaction risk with foreign currency forward contracts. At December 31, 2016, the Company had five open foreign exchange forward contracts relating to service contracts with various amounts maturing monthly through January 2017 with a notional value totaling approximately



$167.9 million. At December 31, 2015, the Company had four open foreign exchange forward contracts relating to service contracts with various amounts maturing monthly through January 2016 with a notional value totaling approximately $93.1 million.

## Interest Rates

Some of the Company's debt is subject to interest at variable rates. As a result, fluctuations in interest rates affect the Company's financial results. The Company attempts to manage interest rate risk and overall borrowing costs through an appropriate mix of fixed and variable rate debt including the utilization of derivative financial instruments, primarily interest rate swaps.

Borrowings under the Company's term loan credit facility and revolving credit facility are subject to variable interest rates, unless fixed through interest rate swaps or other agreements. As of December 31, 2016 and 2015, the Company had approximately $565.0 and $715.0 of unhedged variable rate debt under the term loan credit facility.

During the third quarter of 2013, the Company entered into two fixed-to-variable interest rate swap agreements for its 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 S&P Ratings Services is BB- or lower.

Each quarter-point increase or decrease in the variable rate would result in the Company's interest expense changing by approximately $1.4 per year for the Company's unhedged variable rate debt.

## Item 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Information required by this item is incorporated to the Report of Independent Registered Public Accounting Firm and from the consolidated financial statements, related notes and supplementary data. See the Index on Page F-1.

## Item 9A. CONTROLS AND PROCEDURES

## Disclosure Controls and Procedures

As of the end of the period covered by this report, the Company carried out under the supervision and with the participation of the Company’s management, including the Company’s principal executive officer and principal financial officer, an evaluation of the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended). 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 have been no changes in the Company’s internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) during the fiscal year ended December 31, 2016 that have materially affected, or are 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 U.S. 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 U.S.;

• 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, 2016. 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, 2016, 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, 2016 as stated in its report, which is included herein immediately preceding the Company’s audited financial statements.

# Report of Independent Registered Public Accounting Firm

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, 2016 and 2015, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2016 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, 2016, 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 \( ^{®} \)  together with its subsidiaries (the Company) is a world leading life sciences company that is deeply integrated in guiding patient care, providing comprehensive clinical laboratory and end-to-end drug development services. The Company’s mission is to improve health and improve lives by delivering world-class diagnostic solutions, bringing innovative medicines to patients faster and using technology to provide better care. The Company serves a broad range of customers, including managed care organizations (MCOs), biopharmaceutical companies, governmental agencies, physicians and other healthcare providers (e.g. physician assistants and nurse practitioners, generally referred to herein as physicians), hospitals and health systems, employers, patients and consumers, contract research organizations, food and nutritional companies and independent clinical laboratories. The Company believes that it generated more revenue from laboratory testing than any other company in the world in 2016.

The Company reports its business in two segments, LabCorp Diagnostics (LCD) and Covance Drug Development (CDD). For further financial information about these segments, including information for each of the last three fiscal years regarding revenue, operating income, and other important information, see Note 20 to the Consolidated Financial Statements. In 2016, LCD and CDD contributed 69.9% and 30.1%, respectively, of net revenues to the Company, and in 2015 contributed 72.9% and 27.1%, respectively. Each of the segments' net revenues in 2015 includes the results of the Company's acquisition of Covance Inc. on February 19, 2015.

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 operating 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

LCD recognizes revenue 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 MCOs, 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 2016, 2015 and 2014, approximately 15.5%, 16.0% and 15.0%, respectively, of LCD's revenues were derived directly from the Medicare and Medicaid programs. LCD has capitated agreements with certain MCO customers and recognizes related revenue based on a predetermined monthly contractual rate for each member of the managed care plan regardless of the number of tests performed. In 2016, 2015 and 2014, approximately 3.4%, 3.5% and 3.5%, respectively, of LCD's revenues were derived from such capitated agreements.

CDD recognizes revenue either as services are performed or products are delivered, depending on the nature of the work contracted. Historically, a majority of CDD’s net revenues have been earned under contracts that range in duration from a few months to a few years, but can extend in duration up to five years or longer. Occasionally, CDD also has committed minimum volume arrangements with certain customers. Underlying these arrangements are individual project contracts for the specific services to be provided. These arrangements enable CDD’s customers to secure its services in exchange for which they commit to purchase an annual minimum dollar value of services. Under these types of arrangements, if the annual minimum dollar value of service commitment is not reached, the customer is required to pay CDD for the shortfall. Progress towards the achievement of annual minimum dollar value of service commitments is monitored throughout the year. Annual minimum commitment shortfalls are not included in net revenues until the amount has been determined and agreed to by the customer.

Service contracts generally take the form of fee-for-service or fixed-price arrangements subject to pricing adjustments based on changes in scope. In cases where performance spans multiple accounting periods, revenue is recognized as services are performed, measured on a proportional-performance basis, generally using output measures that are specific to the service provided.



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

Examples of output measures in preclinical services, include among others, the number of slides read, or specimens prepared. Examples of output measures in the clinical trials services, include among others, number of investigators enrolled, number of sites initiated, number of trial subjects enrolled and number of monitoring visits completed, or number of dosings for clinical pharmacology. Revenue is determined by dividing the actual units of work completed by the total units of work required under the contract and multiplying that percentage by the total contract value. The total contract value, or total contractual payments, represents the aggregate contracted price for each of the agreed upon services to be provided. CDD does not have any contractual arrangements spanning multiple accounting periods where revenue is recognized on a proportional-performance basis under which the Company has earned more than an immaterial amount of performance-based revenue (i.e., potential additional revenue tied to specific deliverables or performance). Changes in the scope of work are common, especially under long-term contracts, and generally result in a change in contract value. Once the customer has agreed to the changes in scope and renegotiated pricing terms, the contract value is amended with revenue recognized as described above. Estimates of costs to complete are made to provide, where appropriate, for losses expected on contracts. Costs are not deferred in anticipation of contracts being awarded, but instead are expensed as incurred.

Billing schedules and payment terms are generally negotiated on a contract-by-contract basis. In some cases, CDD bills the customer for the total contract value in progress-based installments as certain non-contingent billing milestones are reached over the contract duration, such as, but not limited to, contract signing, initial dosing, investigator site initiation, patient enrollment or database lock. The term “billing milestone” relates only to a billing trigger in a contract whereby amounts become billable and payable in accordance with a negotiated predetermined billing schedule throughout the term of a project. These billing milestones are generally not performance-based (i.e., there is no potential additional consideration tied to specific deliverables or performance). In other cases, billing and payment terms are tied to the passage of time (e.g., monthly billings). In either case, the total contract value and aggregate amounts billed to the customer would be the same at the end of the project. While CDD attempts to negotiate terms that provide for billing and payment of services prior or within close proximity to the provision of services, this is not always possible, and there are fluctuations in the levels of unbilled services and unearned revenue from period to period. While a project is ongoing, cash payments are not necessarily representative of aggregate revenue earned at any particular point in time, as revenues are recognized when services are provided, while amounts billed and paid are in accordance with the negotiated billing and payment terms.

In some cases, payments received are in excess of revenue recognized. For example, a contract invoicing schedule may provide for an upfront payment of 10% of the full contract value upon contract signing, but at the time of signing performance of services has not yet begun. Payments received in advance of services being provided are deferred as unearned revenue on the balance sheet. As the contracted services are subsequently performed and the associated revenue is recognized, the unearned revenue balance is reduced by the amount of revenue recognized during the period.

In other cases, services may be provided and revenue recognized before the customer is invoiced. In these cases, revenue recognized will exceed amounts billed, and the difference, representing an unbilled receivable, is recorded for the amount that is currently unbillable to the customer pursuant to contractual terms. Once the customer is invoiced, the unbilled services are reduced for the amount billed, and a corresponding account receivable is recorded. All unbilled services are billable to customers within one year from the respective balance sheet date.

Most contracts are terminable with or without cause by the customer, either immediately or upon notice. These contracts often require payment to CDD of expenses to wind down the study or project, fees earned to date and, in some cases, a termination fee or a payment to CDD of some portion of the fees or profits that could have been earned by CDD under the contract if it had not been terminated early. Termination fees are included in net revenues when services are performed and realization is assured. In connection with the management of multi-site clinical trials, CDD pays on behalf of its customers fees to investigators, clinical trial subjects and certain out-of-pocket costs, for which it is reimbursed at cost, without mark-up or profit. Investigator fees are not reflected in net revenues or expenses where CDD acts in the capacity of an agent on behalf of the biopharmaceutical company sponsor, passing through these costs without markup or profit. All other out-of-pocket costs are included in total revenues and expenses.

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

<table><tr><td rowspan="2">Total revenues</td><td colspan="3">Years Ended December 31,</td></tr><tr><td>2016</td><td>2015</td><td>2014</td></tr><tr><td>LCD - net revenue</td><td>$ 6,593.9</td><td>$ 6,199.3</td><td>$ 5,838.0</td></tr><tr><td>CDD - net revenue</td><td>2,844.1</td><td>2,306.4</td><td>173.6</td></tr><tr><td>CDD - reimbursable out-of-pocket expenses</td><td>204.6</td><td>174.4</td><td>—</td></tr><tr><td>Intercompany eliminations</td><td>(0.8)</td><td>—</td><td>—</td></tr><tr><td>Total revenues</td><td>$ 9,641.8</td><td>$ 8,680.1</td><td>$ 6,011.6</td></tr></table>



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

## Reimbursable Out-of-Pocket Expenses

CDD pays on behalf of its customers certain out-of-pocket costs for which the Company is reimbursed at cost, without markup or profit. Out-of-pocket costs paid by CDD are reflected in operating expenses, while the reimbursements received are reflected in revenues in the consolidated statements of operations. CDD excludes from revenue and expense in the consolidated statements of operations fees paid to investigators and the associated reimbursement because CDD acts as an agent on behalf of the biopharmaceutical company sponsors with regard to investigator payments.

## Cost of Revenue

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

## 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 Federal Deposit Insurance Commission, were approximately $28.4 at December 31, 2016. Cash equivalents at December 31, 2016, totaled $268.8, 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 healthcare or biopharmaceutical industry and individuals. However, concentrations of credit risk are limited due to the number of the Company’s customers as well as their dispersion across many different geographic regions.

Although LCD has receivables due from U.S. and state governmental agencies, the Company does not believe that such receivables represent a credit risk since the related healthcare programs are funded by U.S. and state governments, and payment is primarily dependent upon submitting appropriate documentation. Accounts receivable balances (gross) from Medicare and Medicaid were $113.0 and $112.0 at December 31, 2016 and 2015, respectively.

For the Company's operations in Ontario, Canada, the Ontario Ministry of Health and Long-Term Care (Ministry) determines who can establish a licensed community medical laboratory and caps the amount that each of these licensed laboratories can bill the government sponsored healthcare plan. The Ontario government-sponsored healthcare plan covers the cost of commercial 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 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 healthcare providers in the province during the year. The accounts receivable balances from the Ontario government sponsored healthcare plan were CAD $15.8 and CAD $21.3 at December 31, 2016 and 2015, respectively.

The portion of the Company's accounts receivable due from patients comprises the largest portion of credit risk. At December 31, 2016 and 2015, receivables due from patients represented approximately 20.0% and 18.8% of the Company's consolidated gross accounts receivable. The Company applies assumptions and judgments including historical collection experience for assessing collectability 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



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

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.

The following represents a reconciliation of basic earnings per share to diluted earnings per share:

<table><tr><td rowspan="2"></td><td colspan="4">2016</td><td colspan="4">2015</td><td colspan="4">2014</td></tr><tr><td>Income</td><td>Shares</td><td>Per Share Amount</td><td>Income</td><td>Shares</td><td>Per Share Amount</td><td>Income</td><td>Shares</td><td>Per Shared Amount</td><td>Income</td><td>Shares</td><td>Per Shared Amount</td></tr><tr><td>Basic earnings per share</td><td>$ 732.1</td><td>102.5</td><td>$ 7.14</td><td>$ 437.6</td><td>98.8</td><td>$ 4.43</td><td>$ 511.2</td><td>84.8</td><td>$ 6.03</td><td></td><td></td><td></td><td></td></tr><tr><td>Stock options</td><td>—</td><td>1.5</td><td></td><td>—</td><td>1.2</td><td></td><td>—</td><td>1.1</td><td></td><td></td><td></td><td></td><td></td></tr><tr><td>Restricted stock awards and other</td><td>—</td><td>—</td><td></td><td>—</td><td>—</td><td></td><td>—</td><td>—</td><td></td><td></td><td></td><td></td><td></td></tr><tr><td>Effect of convertible debt, net of tax</td><td>—</td><td>0.3</td><td></td><td>—</td><td>0.6</td><td></td><td>—</td><td>0.5</td><td></td><td></td><td></td><td></td><td></td></tr><tr><td>Diluted earnings per share</td><td>$ 732.1</td><td>104.3</td><td>$ 7.02</td><td>$ 437.6</td><td>100.6</td><td>$ 4.35</td><td>$ 511.2</td><td>86.4</td><td>$ 5.91</td><td></td><td></td><td></td><td></td></tr></table>

The following table summarizes the potential common shares not included in the computation of diluted earnings per share because their impact would have been antidilutive:

<table><tr><td rowspan="2"></td><td colspan="4">Years Ended December 31,</td></tr><tr><td>2016</td><td>2015</td><td>2014</td><td></td></tr><tr><td>Stock options</td><td>—</td><td>—</td><td>—</td><td></td></tr></table>

## 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, substantially all of which have maturities when purchased of three months or less.

## Inventories

Inventories, consisting primarily of purchased laboratory and customer supplies and finished goods, are stated at the lower of cost (first-in, first-out) or market. Supplies accounted for $171.7 and $157.7 and finished goods accounted for $33.5 and $33.3 of total inventory at December 31, 2016 and 2015, respectively.

## Prepaid Expenses and Other

In connection with the management of multi-site clinical trials, CDD pays on behalf of its customers certain out-of-pocket costs, for which the Company is reimbursed at cost, without markup or profit. Amounts receivable from customers in connection with such out-of-pocket pass-through costs are included in prepaid expenses and other in the accompanying consolidated balance sheets and totaled $97.1 at December 31, 2016 and $92.5 at December 31, 2015.

Also included in prepaid expenses and other current assets are assets held for sale. The Company records long-lived assets as held for sale when a plan to sell the asset has been initiated and all other held for sale criteria have been satisfied. Assets classified as held for sale of $51.2 as of December 31, 2016 are recorded in other current assets on the consolidated balance sheet at the lower of their carrying value or fair value less cost to sell. The Company also recorded a $3.6 gain on the sale of these assets held for sale. There were $72.4 assets held for sale as of December 31, 2015.

## 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



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

and amortization expense is computed on all classes of assets based on their estimated useful lives, as indicated below, using the straight-line method.

<table><tr><td></td><td>Years</td></tr><tr><td>Buildings and building improvements</td><td>10 - 40</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 (R&D) 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 or whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. In 2015, the Company changed the timing of its annual impairment testing from the end of the year to the beginning of the fourth quarter. In accordance with the 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.

Step One of the goodwill impairment test includes the estimation of the fair value of each reporting unit as compared to the carrying value of the reporting unit. Reporting units are businesses with discrete financial information that is available and reviewed by management. The Company estimates the fair value of a reporting unit using both income-based and market-based valuation methods. The income-based approach is based on the reporting unit's forecasted future cash flows that are discounted to the present value using the reporting unit's weighted average cost of capital. For the market-based approach, the Company utilizes a number of factors such as publicly available information regarding the market capitalization of the Company as well as operating results, business plans, market multiples, and present value techniques. Based upon the range of estimated values developed from the income and market-based methods, the Company determines the estimated fair value for the reporting unit. If the estimated fair value of the reporting unit exceeds the carrying value, the goodwill is not impaired and no further review is required. However, if the estimated fair value is less than the carrying value, the Company performs the second step of the goodwill impairment test to measure the amount of the impairment, if any. The second step involves a hypothetical allocation of the estimated fair value of the reporting unit to its tangible and intangible assets (excluding goodwill) and liabilities as if the reporting unit were newly acquired, which results in an implied fair value of the goodwill. The amount of the impairment charge is the excess of the recorded goodwill, if any, over the implied fair value of the goodwill.

Management concluded that no triggering events occurred during 2016 related to goodwill and indefinite-lived intangible assets. As such, management performed its annual goodwill and intangible asset impairment testing as of the beginning of the fourth quarter of 2016. The Company elected to perform the qualitative assessment for goodwill and intangible assets for all reporting units except two of the CDD reporting units and the indefinite-lived Canadian licenses for which the quantitative assessment was used.

In this qualitative assessment, the Company considered relevant events and circumstances for each reporting unit, including (i) current year results, (ii) financial performance versus management’s annual and five-year strategic plans, iii) changes in the reporting unit carrying value since prior year, (iv) industry and market conditions in which the reporting unit operates, (v) macroeconomic conditions, including discount rate changes, and (vi) changes in products or services offered by the reporting unit.



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

If applicable, performance in recent years was compared to forecasts included in prior valuations. Based on the results of the qualitative assessment, the Company concluded that it was not more likely than not that the carrying values of the goodwill and intangible assets were greater than their fair values, and that further quantitative testing was not necessary.

In 2016, the Company utilized an income approach to determine the fair value of two of the CDD reporting units, with $460.7 and $223.9 of goodwill as of September 30, 2016. Based upon the results of the quantitative assessment, the Company concluded that the fair value of these reporting units was greater than the carrying value.

In 2016, the Company also utilized an income approach to determine the fair value of its Canadian reporting unit and its indefinite-lived assets consisting of acquired Canadian licenses. Based upon the results of the quantitative assessment, the Company concluded that the fair value of the indefinite-lived Canadian licenses was greater than the carrying value.

It is possible that the Company's conclusions regarding impairment or recoverability of goodwill or intangible assets in any reporting unit could change in future periods. There can be no assurance that the estimates and assumptions used in the Company's goodwill and intangible asset impairment testing performed as of the beginning of the fourth quarter of 2016 will prove to be accurate predictions of the future, if, for example, (i) the businesses do not perform as projected, (ii) overall economic conditions in 2017 or future years vary from current assumptions (including changes in discount rates), (iii) business conditions or strategies for a specific reporting unit change from current assumptions, including loss of major customers, (iv) investors require higher rates of return on equity investments in the marketplace or (v) enterprise values of comparable publicly traded companies, or actual sales transactions of comparable companies, were to decline, resulting in lower multiples of revenues and EBITDA. The Company will particularly monitor the financial performance of and assumptions for the two of the CDD reporting units for which an income approach was performed in 2016. A future impairment charge for goodwill or intangible assets could have a material effect on the Company's consolidated financial position and results of operations.

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 impaired long-lived assets of $39.7, for the year ended 2015.

## 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 colspan="2">Years</td></tr><tr><td>Customer relationships</td><td>10</td><td>- 36</td></tr><tr><td>Patents, licenses and technology</td><td>3</td><td>- 15</td></tr><tr><td>Non-compete agreements</td><td>5</td><td>- 10</td></tr><tr><td>Trade names</td><td>5</td><td>- 15</td></tr></table>

## Debt Issuance Costs

The costs related to the issuance of debt are capitalized, netted against the related debt for presentation purposes 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 based on 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.



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

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, 2016 and 2015.

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.

## 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 R&D costs as incurred.

## Foreign Currencies

For subsidiaries outside of the U.S. that operate in a local currency environment, income and expense items are translated to U.S. dollars at the monthly average rates of exchange prevailing during the period, assets and liabilities are translated at period-end exchange rates and equity accounts are translated at historical exchange rates. Translation adjustments are accumulated in a separate component of shareholders' equity in the consolidated balance sheets and are included in the determination of comprehensive income in the consolidated statements of comprehensive earnings and consolidated statements of changes in shareholders' equity. Transaction gains and losses are included in the determination of net income in the consolidated statements of operations.

## New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (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. GAAP. 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. As originally issued, the new revenue recognition standard would be effective for the Company beginning January 1, 2017. On July 9, 2015, the FASB approved the proposal to defer the effective date of this standard by one year. The standard will be effective for the Company beginning January 1, 2018, with early adoption permitted for annual periods beginning after December 16, 2016.

The Company plans to adopt the full retrospective method effective January 1, 2018, and is continuing to evaluate the expected impact of the standard. Currently, the Company has completed the initial adoption analysis for LCD and expects this standard to impact LCD margins due to the recording of LCD bad debt expense against net revenues (versus selling, general and administrative expense) as an implicit price concession. The Company has also completed the initial adoption analysis for each of the major revenue streams within CDD and expects this standard to also impact CDD margins due to the elimination of gross-to-net reporting of reimbursable out-of-pocket expenses and the elimination of accounting for fees paid to investigators as an agent. In addition, the Company expects the timing of revenue recognition in the clinical business to accelerate, as revenue from study-related change orders and fixed price gains is recognized ratably over the service period (versus lump-sum recognition due to a change order or when studies are near completion). The detailed contract review must be completed before the Company can quantify the expected impact of the standard. The Company also anticipates an increase in the level of required financial statement disclosures.

In November 2015, the FASB issued a new accounting standard that requires deferred tax liabilities and assets to be classified as noncurrent on the consolidated balance sheet. The Company early adopted this standard on a full-retrospective basis as of March 31, 2016. The adoption of this standard did not have a material impact on the consolidated financial statements.

In January 2016, the FASB issued a new accounting standard that addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. A financial instrument is defined as cash, evidence of ownership interest in a company or other entity, or a contract that both: (i) imposes on one entity a contractual obligation either to deliver cash or another financial instrument to a second entity or to exchange other financial instruments on potentially unfavorable terms with the second entity and (ii) conveys to that second entity a contractual right either to receive cash or another financial instrument from the first entity or to exchange other financial instruments on potentially favorable terms with the first entity. The standard will be effective for the Company beginning January 1, 2018, with early adoption permitted. The Company is evaluating the impact that this new standard will have on the consolidated financial statements.

In February 2016, the FASB issued a new accounting standard that sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for based on guidance similar to current guidance for operating leases. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. The standard is effective on January 1, 2019, with early adoption permitted. The Company is evaluating the impact that this new standard will have on the consolidated financial statements.

In March 2016, the FASB issued a new accounting standard intended to simplify aspects of share-based payment accounting. The standard changes how companies account for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as the classification of related matters in the statement of cash flows. The update is effective on January 1, 2017, with early adoption permitted. The Company early adopted this standard in the quarter ended September 30, 2016. As a result of the adoption, a tax benefit of $14.0 was recorded for the year ended December 31, 2016.

In March 2016, the FASB issued a new accounting standard intended to simplify aspects of the equity method of accounting. The standard eliminates the requirement that when an investment qualifies for use of the equity method of accounting as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The standard requires that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The update is effective on January 1, 2017, with early adoption permitted. The adoption of this standard is not expected to have a material impact on the consolidated financial statements.

In June 2016, the FASB issued a new accounting standard intended to provide financial statement users with more decision-useful information about expected credit losses and other commitments to extend credit held by the reporting entity. The standard replaces the incurred loss impairment methodology in current GAAP with one that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The update is effective on January 1, 2020, with early adoption permitted. The Company is currently evaluating this new standard and the impact it will have on the consolidated financial statements.

In August 2016, the FASB issued a new accounting standard that will make eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. This update is effective on January 1, 2018, and will require adoption on a retrospective basis. The Company is currently evaluating the impact the application of this new standard will have on the Company’s consolidated financial statements.

In January 2017, the FASB issued a new accounting standard that changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. This update is effective on January 1, 2018, with early adoption permitted. The Company is currently evaluating the impact the application of this new standard will have on the consolidated financial statements.

## Reclassifications

The Company has reclassified debt issuance costs from prepaid expenses and other assets, net to direct deductions from the associated debt liability in the December 31, 2015 consolidated balance sheet in accordance with the implementation of a FASB standard update that the company adopted as of January 1, 2016.

In addition, the Company has reclassified short-term deferred tax assets and short-term deferred tax liabilities to net long-term deferred tax assets and net long-term deferred tax liabilities by jurisdiction, respectively, in the December 31, 2015 consolidated balance sheet in accordance with the implementation of a FASB standard update that the Company adopted as of January 1, 2016.

The Company changed its financial statement classification for certain gross receipts taxes in 2016, removing these taxes from its provision for income taxes and moving this expense into selling, general and administrative expenses. Certain gross receipts taxes of $6.1 were reclassified in both 2015 and 2014.

As a result of the early adoption of the accounting standard update associated with simplifying several aspects of share-based compensation, certain reclassifications have been made to prior period financial statements to conform with the current period presentation. For further details regarding the impact of the new standard, see New Accounting Pronouncements, above.

## 2. BUSINESS ACQUISITIONS

During the year ended December 31, 2016, the Company acquired various laboratories and related assets for approximately $548.6 in cash (net of cash acquired).

The Company completed the acquisition of Sequenom, Inc., a market leader in non-invasive prenatal testing, women's health and reproductive genetics on September 7, 2016 through a cash tender offer for $2.40 per share, or a transaction price of $249.1, net of cash received, and acquired $130.0 of debt. The Sequenom purchase consideration has been allocated to the estimated fair market value of the net assets acquired, including approximately $146.6 in identifiable intangible assets (primarily customer relationships, technology, and trade names) with weighted-average useful lives of approximately 14.6 years; $45.1 in deferred tax liabilities (relating to identifiable intangible assets); and a residual amount of non-tax deductible goodwill of approximately $206.0. While the purchase price allocation is substantially complete, it is still preliminary and subject to change. The areas of the purchase price allocation that are not yet finalized relate primarily to the impact of finalizing deferred taxes and goodwill. Accordingly, adjustments may be made as additional information is obtained about the facts and circumstances that existed as of the valuation date. The Company expects the purchase price allocation to be finalized during the second half of 2017. Any adjustments will be recorded in the period in which they were identified.

The Company also acquired various other laboratories and related assets for approximately $299.5 in cash (net of cash acquired). The purchase consideration for these acquisitions has been allocated to the estimated fair market value of the net assets acquired, including approximately $126.2 in identifiable intangible assets (primarily customer relationships) and a residual amount of goodwill of approximately $192.3. 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. While the purchase price allocation for one of the fourth quarter acquisitions is substantially complete, it is still preliminary and subject to change. The areas of the purchase price allocation that are not yet finalized relate primarily to the intangible assets, goodwill and the impact of finalizing deferred taxes. Accordingly, adjustments may be made as additional information is obtained about the facts and circumstances that existed as of the valuation date. The Company expects the purchase price allocation to be finalized during the first half of 2017. Any adjustments will be recorded in the period in which they were identified.

On January 9, 2017, the Company entered into a definitive agreement to purchase select operating assets of the outreach laboratory operations of a healthcare system in the Northeast. In addition, on February 23, 2017, the Company announced that it has signed a definitive agreement to purchase a premier medical reference laboratory and healthcare solutions company.

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. The Company financed the Acquisition with $3,900.0 of debt, 15.3 shares of its common stock and $488.2 of available cash, $400.0 of which was derived from a bridge term loan credit facility. 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 (together, the Acquisition Notes). The Company also entered into a $1,000.0 term loan facility which was advanced in full on the Acquisition Date. The term loan credit facility will mature five years after the closing date of the Acquisition and may be prepaid without penalty.

The valuation of acquired assets and assumed liabilities at the Acquisition Date include the following:

## 3. RESTRUCTURING AND OTHER SPECIAL CHARGES

During 2016, the Company recorded net restructuring charges of $58.4; $15.8 within LCD and $42.6 within CDD. The charges were comprised of $30.9 in severance and other personnel costs and $33.8 in facility-related costs primarily associated with general integration activities. A substantial portion of these costs relate to the planned closure of duplicative data center operations and other facilities. The charges were offset by the reversal of previously established reserves of $2.8 in unused severance and $3.5 in unused facility-related costs. The Company incurred additional legal and other costs of $4.6 relating to the wind down of its minimum volume service contract operations and incurred $8.0 in acquisition fees and expenses. The Company also recorded $6.9 in consulting expenses relating to fees incurred as part of its Acquisition integration costs and compensation analysis, along with $2.5 in short-term equity retention arrangements relating to the Acquisition and $8.9 of accelerated equity compensation and other final compensation relating to executive transition, along with $9.0 of non-capitalized costs associated with the implementation of a major system as part of LaunchPad, LCD's comprehensive, enterprise-wide business process improvement initiative (all recorded in selling, general and administrative expenses).

During 2015, the Company recorded net restructuring charges of $113.9; $39.2 within LCD and $74.7 within CDD. The charges were comprised of $59.2 in severance and other personnel costs and $55.8 in facility-related costs primarily associated with general integration activities. A substantial portion of these costs relate to the planned closure of two CDD operations that serviced a minimum volume contract that expired on October 31, 2015. These charges were offset by the reversal of previously established reserves of $1.1 in unused facility related costs. Included within the facility-related charges noted above is a $26.7 asset impairment charge relating to CDD lab and customer service applications that will no longer be used.

In addition, during 2015, the Company recorded $25.6 in consulting expenses (recorded in selling, general and administrative expenses) relating to fees incurred as part of LaunchPad as well as Covance integration costs and employee compensation studies, along with $5.4 in short-term equity retention arrangements relating to the acquisition of Covance and $0.3 of accelerated equity compensation relating to the retirement of a Company executive (all recorded in selling, general and administrative expenses).

## 5. JOINT VENTURE PARTNERSHIPS AND EQUITY METHOD INVESTMENTS

At December 31, 2016, the Company had investments in the following unconsolidated joint venture partnerships and equity method investments:

<table><tr><td>Locations</td><td>Net Investment</td><td>Interest Owned</td></tr><tr><td>Joint Venture Partnerships:</td><td></td><td></td></tr><tr><td>Alberta, Canada (2)</td><td>$ 44.9</td><td>43.37%</td></tr><tr><td>Florence, South Carolina</td><td>10.3</td><td>49.00%</td></tr><tr><td>Equity Method Investments:</td><td></td><td></td></tr><tr><td>Various</td><td>3.3</td><td>various</td></tr></table>

The joint venture agreements that govern the conduct of business of these partnerships mandate unanimous agreement between partners on all major business decisions as well as providing other participating rights to each partner. The equity method investments represent the Company’s purchase of shares in clinical diagnostic companies. The investments are accounted for under the equity method of accounting as the Company does not have control of these investments. The Company has no material obligations or guarantees to, or in support of, these unconsolidated investments and their operations.

Effective June 30, 2015, the Company dissolved a joint venture partnership that had been located in Milwaukee, Wisconsin.

Condensed unconsolidated financial information for joint venture partnerships and equity method investments is shown in the following table.

<table><tr><td>As of December 31:</td><td>2016</td><td>2015</td></tr><tr><td>Current assets</td><td>$ 24.3</td><td>$ 22.6</td></tr><tr><td>Other assets</td><td>16.9</td><td>19.2</td></tr><tr><td>Total assets</td><td>$ 41.2</td><td>$ 41.8</td></tr><tr><td>Current liabilities</td><td>$ 15.5</td><td>$ 17.3</td></tr><tr><td>Other liabilities</td><td>0.3</td><td>1.3</td></tr><tr><td>Total liabilities</td><td>15.8</td><td>18.6</td></tr><tr><td>Partners&#x27; equity</td><td>25.4</td><td>23.2</td></tr><tr><td>Total liabilities and partners&#x27; equity</td><td>$ 41.2</td><td>$ 41.8</td></tr><tr><td>For the period January 1 - December 31:</td><td>2016</td><td>2015</td></tr><tr><td>Net revenues</td><td>$ 156.7</td><td>$ 213.7</td></tr><tr><td>Gross profit</td><td>45.7</td><td>54.3</td></tr><tr><td>Net earnings</td><td>20.3</td><td>20.1</td></tr></table>

The Company’s recorded investment in one of its Alberta joint venture partnerships at December 31, 2016 includes $34.9 of value assigned to that partnership’s Canadian license to conduct diagnostic testing services in the province. Substantially all of the joint venture’s revenue is received as reimbursement from the Alberta government’s healthcare programs. While the Canadian license provides 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. A decision by the provincial

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

government to limit or reduce its reimbursement of laboratory diagnostic services would have a negative impact on the profits and cash flows the Company derives from the joint venture. In December 2013, Alberta Health Services (AHS), the Alberta government's healthcare program, issued a request for proposals for laboratory services that included the scope of services performed by the Canadian partnership. In October 2014, AHS informed the Canadian partnership that it had not been selected as the preferred proponent. In November 2014, the Canadian partnership submitted a vendor bid appeal upon the belief that there were significant flaws and failures in the conduct of the request for proposal process, which drove to a biased conclusion. AHS established a Vendor Bid Appeal Panel to hear the appeal, and the hearing occurred in February 2015. In August 2015, AHS was directed to cancel the request for proposal process. Subsequently, the Canadian partnership entered into a one-year extension through March 31, 2017 of its existing contract with AHS. In August 2016, AHS and the Canadian partnership reached an agreement to extend the contract for five additional years through March 2022, with the intent to have the services provided pursuant to the contract transferred to AHS at the end of the five-year period. In consideration of AHS acquiring the assets and assuming liabilities in accordance with the parties' agreement, AHS will pay CAD $50.0 to the partnership when the transfer is effective, subject to a working capital adjustment. The Company will amortize the value of the partnership's Canadian license to its residual over the remaining term of the agreement.

## Credit Facilities

On November 2, 2014, in connection with entering into the definitive merger agreement to acquire Covance (Merger Agreement), 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 Acquisition date.

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 the Acquisition Date. The term loan credit facility will mature five years after the Acquisition date and may be prepaid without penalty. The term loan balance at December 31, 2016 was $565.0.

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 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 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. There were no balances outstanding on the Company's current revolving credit facility at December 31, 2016 or December 31, 2015.



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

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 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 the Acquisition Date. On March 16, 2015, the Company elected to prepay the bridge facility without penalty.

Under the term loan facility and the revolving 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 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 Acquisition Notes. From and after the acquisition closing date, the leverage ratio was required to have been 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 revolving credit facility at December 31, 2016 and 2015. As of December 31, 2016, the ratio of total debt to consolidated EBITDA was 3.1 to 1.0.

The term loan credit facility accrues 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 revolving credit facility 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 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 revolving credit facility, at a per annum rate ranging from 0.125% to 0.40%. The interest margin applicable to the credit facilities, and the facility fee and letter of credit fees payable under the revolving credit facility, are based on the Company’s senior credit ratings as determined by S&P and Moody’s, which are currently BBB and Baa2, respectively.

As of December 31, 2016, the effective interest rate on the revolving credit facility was 1.9%, and the effective interest rate on the term loan was 2.0%.

## Zero-Coupon Convertible Subordinated Notes

The Company had $46.0 and $105.4 aggregate principal amount at maturity of zero-coupon convertible subordinated notes (the Notes) due 2021 outstanding at December 31, 2016 and 2015, 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) 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 2016 was $76.27.

2) The credit rating assigned to the notes by S&P Ratings Services is at or below BB-.

3) The Notes are called for redemption.

4) 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.

During 2016 and 2015, the Company settled notices to convert $59.4 and $1.5 aggregate principal amount at maturity of its zero-coupon subordinated notes with a conversion value of $53.7 and $1.3, respectively. The total cash used for these settlements was $53.7 and $1.3 and the Company also issued 0.4 and 0.0 additional shares of common stock, respectively. As a result of these conversions, in 2016 and 2015 the Company also reversed approximately $4.9 and $0.4, respectively, of deferred tax liability to reflect the tax benefit realized upon issuance of the shares.

On September 12, 2016, the Company announced that for the period of September 12, 2016 to March 10, 2017, 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, 2016, in addition to the continued accrual of the original issue discount.

On January 3, 2017, 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 $1,000.00 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 the 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, 2017, 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 Friday, March 31, 2017.

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 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.

For 2015 and 2014, a portion of the tax benefit associated with option exercises from stock plans, which reduce taxes payable, were recorded through additional paid-in capital. The benefits recorded through additional paid-in capital were approximately $13.1 and $5.9 in 2015 and 2014, respectively.

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

The effective rate for 2016 was favorably impacted by foreign earnings taxed at rates lower than the U.S. statutory rate and the early adoption of the share-based compensation standard.

The effective rate for 2015 was unfavorably impacted by restructuring and acquisition items, the recording of additional uncertain tax reserves, and a decrease in the benefit recorded from releasing uncertain tax reserves. The 2015 rate was favorably impacted by foreign earnings taxed at rates lower than the U.S. statutory rate.

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

The Company has U.S. federal tax loss carryforwards of approximately $390.7, which expire periodically through 2035. The increase in the U.S. federal tax loss carryforwards results from the acquisition of Sequenom, Inc. The utilization of tax loss carryforwards is limited due to change of ownership rules, however, at this time, the Company expects to fully utilize substantially all U.S. federal tax loss carryforwards with the exception of approximately $3.9 for which a full valuation allowance has been provided. The Company has U.S. state tax loss carryforwards of $392.4, which also expire periodically through 2035, and on which a valuation allowance of $336.3 has been provided. The Company's U.S. state loss carryforwards increased as a result of the finalization of the Covance Inc. purchase price accounting. The Company has foreign tax loss carryforwards of $41.6 of which $29.3 has a full valuation allowance. Most of the foreign losses have an indefinite carryover. In addition to the foreign net operating losses, the Company has a foreign capital loss carryforward of $6.9. The capital loss has an indefinite life and has a full valuation allowance.

The valuation allowance increased from $15.1 in 2015 to $31.3 in 2016 primarily due to the finalization of the Covance Inc. purchase price accounting and the recording of state tax loss carryforwards with a full valuation allowance.

Unrecognized income tax benefits were $18.4 and $24.2 at December 31, 2016 and 2015, respectively. It is anticipated that the amount of the unrecognized income tax benefits will change within the next 12 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 $9.9 and $12.7 as of December 31, 2016 and 2015, respectively. During the years ended December 31, 2016, 2015 and 2014, the Company recognized $1.2, $1.8 and $2.2, respectively, in interest and penalties expense, which was offset by a benefit from reversing previous accruals for interest and penalties of $4.0, $2.2 and $3.3, respectively.

The following table shows a reconciliation of the unrecognized income tax benefits, excluding interest and penalties, from uncertain tax positions for the years ended December 31, 2016, 2015 and 2014:

<table><tr><td></td><td colspan="2">2016</td><td colspan="2">2015</td><td colspan="2">2014</td></tr><tr><td>Balance as of January 1</td><td>$     24.2</td><td>$     16.7</td><td>$     25.6</td><td></td><td></td><td></td></tr><tr><td>Increase in reserve for tax positions taken in the current year</td><td>2.3</td><td></td><td>4.1</td><td></td><td>—</td><td></td></tr><tr><td>Increase in reserve as a result of acquisition</td><td></td><td>—</td><td>8.5</td><td></td><td>—</td><td></td></tr><tr><td>Decrease in reserve as a result of lapses in the statute of limitations</td><td>(8.1)</td><td></td><td>(5.1)</td><td></td><td>(8.9)</td><td></td></tr><tr><td>Balance as of December 31</td><td>$     18.4</td><td>$     24.2</td><td>$     16.7</td><td></td><td></td><td></td></tr></table>

As of December 31, 2016 and 2015, $18.4 and $24.2, respectively, are the approximate amounts 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 2012. Substantially all material state and local and foreign income tax matters have been concluded through 2011 and 2004, respectively.

The Internal Revenue Service concluded the examination of the Company's 2014 federal consolidated income tax return, which did not include Covance Inc., in the third quarter of 2016. In the third quarter, the Company was notified that Covance Inc.'s 2013 federal consolidated income tax return was under examination. The Canada Revenue Agency is currently examining the Company's 2013 and 2014 Canadian subsidiaries' tax returns. The Company has various state and foreign income tax examinations ongoing throughout the year. The Company believes adequate provisions have been recorded related to all open tax years.

The Company changed its method for accounting for foreign earnings at the beginning of 2015 as a result of the Acquisition. Prior to the Acquisition, the Company provided tax for substantially all of its foreign earnings. Other than certain amounts associated with the Acquisition, the Company considers its foreign earnings are now permanently invested outside of the U.S. as it intends to leave its future generated unremitted foreign earnings invested indefinitely outside the U.S. given its expanded global profile. It is not practical to estimate the amount of additional tax that could be payable if accumulated earnings were remitted. Total unremitted foreign earnings for which income tax has not been provided are approximately $3,144.3 as of December 31, 2016.

## 14. STOCK COMPENSATION PLANS

## Stock Incentive Plans

There are currently 11.2 shares authorized for issuance under the Laboratory Corporation of America Holdings 2016 Omnibus Incentive Plan (the Plan) and at December 31, 2016 there were 9.6 additional shares available for grant under the Plan. The Plan was approved by shareholders at the 2016 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 three 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:



# LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES

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

<table><tr><td></td><td>Number of Options</td><td>Weighted-Average Exercise Price per Option</td><td>Weighted-Average Remaining Contractual Term</td><td>Aggregate Intrinsic Value</td></tr><tr><td>Outstanding at December 31, 2015</td><td>2.3</td><td>$ 81.40</td><td></td><td></td></tr><tr><td>Granted</td><td>—</td><td>—</td><td></td><td></td></tr><tr><td>Exercised</td><td>(0.7)</td><td>78.12</td><td></td><td></td></tr><tr><td>Cancelled</td><td>—</td><td>—</td><td></td><td></td></tr><tr><td>Outstanding at December 31, 2016</td><td>1.6</td><td>$ 82.43</td><td>4.1</td><td>$ 72.7</td></tr><tr><td>Vested and expected to vest at December 31, 2016</td><td>1.6</td><td>$ 82.43</td><td>4.1</td><td>$ 72.7</td></tr><tr><td>Exercisable at December 31, 2016</td><td>1.6</td><td>$ 82.43</td><td>4.1</td><td>$ 72.7</td></tr></table>

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 2016 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, 2016. 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, 2016, 2015, and 2014 were as follows:

<table><tr><td></td><td>2016</td><td>2015</td><td>2014</td></tr><tr><td>Cash received by the Company</td><td>$ 52.6</td><td>$ 82.6</td><td>$ 98.5</td></tr><tr><td>Tax benefits realized</td><td>$ 13.6</td><td>$ 16.2</td><td>$ 12.3</td></tr><tr><td>Aggregate intrinsic value</td><td>$ 35.5</td><td>$ 42.2</td><td>$ 32.1</td></tr></table>

The following table summarizes information concerning currently outstanding and exercisable options.

<table><tr><td colspan="4">Options Outstanding</td><td colspan="2">Options Exercisable</td></tr><tr><td></td><td></td><td></td><td colspan="2">Weighted Average</td><td>Weighted Average Exercise Price</td></tr><tr><td>Range of Exercise Prices</td><td>Number Outstanding</td><td>Remaining Contractual Life</td><td>Average Exercise Price</td><td>Number Exercisable</td><td></td></tr><tr><td>$59.38 - 67.60</td><td>0.1</td><td>2.1</td><td>$60.46</td><td>0.1</td><td>$60.46</td></tr><tr><td>$67.61 - 75.63</td><td>0.3</td><td>2.6</td><td>$72.40</td><td>0.3</td><td>$72.40</td></tr><tr><td>$75.64 - 80.37</td><td>0.1</td><td>2.0</td><td>$73.60</td><td>0.1</td><td>$73.60</td></tr><tr><td>$80.38 - 98.49</td><td>1.1</td><td>4.8</td><td>$87.46</td><td>1.1</td><td>$87.46</td></tr><tr><td></td><td>1.6</td><td>4.1</td><td>$82.43</td><td>1.6</td><td>$82.43</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 2016, 2015 and 2014, expense related to the Company’s stock option plan totaled $0.0, $2.2 and $6.9, respectively. The Company did not grant any options to employees during 2016, 2015, or 2014.

## 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 units typically vest annually in equal one third increments beginning on the first anniversary of the grant. A performance share grant in 2014 represents a three-year award opportunity for the period 2014-2016, and if earned, vests fully (to the extent earned) in the first quarter of 2017. A performance share grant in 2015 represents a three-year award opportunity for the period of 2015-2017 and, if earned, vests fully (to the extent earned) in the first quarter of 2018. A performance share grant in 2016 represents a three-year award opportunity for the period of 2016-2018 and, if earned, vests fully (to the extent earned) in the first quarter of 2019. 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 2016, 2015 and 2014, total restricted stock, restricted stock unit and performance share compensation expense was $104.1, $83.8 and $34.8, respectively.

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

The following table shows a summary of non-vested shares for the year ended December 31, 2016:

<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, 2016</td><td>1.5</td><td>109.00</td></tr><tr><td>Granted</td><td>1.0</td><td>103.59</td></tr><tr><td>Vested</td><td>(0.8)</td><td>100.70</td></tr><tr><td>Canceled</td><td>(0.1)</td><td>110.62</td></tr><tr><td>Non-vested at December 31, 2016</td><td>1.6</td><td>108.23</td></tr></table>

As of December 31, 2016, there was $58.2 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 1.8 years.

## Employee Stock Purchase Plan

Under the 2016 Employee Stock Purchase Plan, the Company is authorized to issue 2.5 shares of common stock. 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 each of 2016, 2015 and 2014, respectively, under either the 2016 Employee Stock Purchase Plan or the prior plan, which began in 1997 and was amended in 1999, 2004, 2008 and 2012. For 2016, 2015 and 2014, expense related to the Company’s employee stock purchase plan was $5.5, $4.1 and $4.0, 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 rowspan="2">Fair value of the employee’s purchase right</td><td colspan="2">2016</td><td colspan="2">2015</td><td colspan="2">2014</td></tr><tr><td>$</td><td>23.32</td><td>$</td><td>21.95</td><td>$</td><td>19.48</td></tr><tr><td>Valuation assumptions</td><td></td><td></td><td></td><td></td><td></td><td></td></tr><tr><td>Risk free interest rate</td><td></td><td>0.5%</td><td></td><td>0.3%</td><td></td><td>0.1%</td></tr><tr><td>Expected volatility</td><td></td><td>0.2</td><td></td><td>0.2</td><td></td><td>0.2</td></tr><tr><td>Expected dividend yield</td><td></td><td>—</td><td></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; commercial and contract disputes; professional liability; employee-related matters; and inquiries, including subpoenas and other civil investigative demands, from governmental agencies and Medicare or Medicaid payers and MCOs 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 parties, including physicians and other healthcare providers (e.g. physician assistants and nurse practitioners). The Company works cooperatively to respond to appropriate requests for information.

The Company also is 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 U.S., federal or state healthcare 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 healthcare field today.

The Company believes that it is in compliance in all material respects with all statutes, regulations and other requirements applicable to its commercial laboratory operations and drug development support services. The healthcare diagnostics and drug development industries are, 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 the 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 in preliminary stages, and many of these cases seek an indeterminate amount of damages. The Company records an aggregate legal reserve, which is determined using 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 the proceedings 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 proceedings, however, the Company does not believe, based on currently available information, that the outcomes 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 Hunter Labs Settlement Agreement, the Company recorded a litigation settlement expense of $34.5 in the second quarter of 2011 (net of a previously recorded reserve of $15.0) and paid the settlement amount of $49.5 in the third quarter of 2011. 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 2011, the California legislature enacted Assembly Bill No. 97, which imposed a 10.0% Medi-Cal payment cut on most providers of healthcare services, including clinical laboratories. This 10% cut is currently being applied to the rates that would otherwise be applicable. In 2012, the California legislature enacted Assembly Bill No. 1494, which directed the Department of Healthcare Services (DHCS) to establish new reimbursement rates for Medi-Cal commercial laboratory services based on payments made to California clinical laboratories for similar services by other third-party payers, and provided that until the new rates are set through this process, Medi-Cal payments for commercial laboratory services will be reduced (in addition to a 10.0% 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 80.0% of the lowest maximum allowance established under the 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 April 2015, CMS approved a 10.0% payment reduction under Assembly Bill No. 1494. The new rate methodology established new rates that were effective July 1, 2015, but these new rates were not entered into the state computer system until February, 2016. Based on reported 2015 payment data, new rates were established to be effective July 1, 2016, but due to computer system delays, these rates have not been fully implemented yet and recoupments associated with these changes are anticipated, but have not begun. 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 U.S. Department of Health & Human Services Office of Inspector General's regional office in New York. On August 17, 2011, the United States District Court for 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 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 and Plaintiff was granted the right to repeal. On January 11, 2016, Plaintiff filed a motion requesting leave to file an amended complaint under seal and to vacate the briefing schedule for the Company's motion to dismiss while the government reviews the amended complaint. The Court granted the motion and vacated the briefing dates. Plaintiff then filed an amended complaint under seal. The Company will vigorously defend the lawsuit.

In addition, the Company has received various 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 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 lawsuit, 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. The Company’s Motion to Dismiss was denied in February 2015. In December 2016, the Court granted the Company’s Motion for Partial Summary Judgment. The Company will vigorously defend the remaining claims in 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 State of Georgia filed a Notice of Declination on August 13, 2012, before the Company was served with the Complaint. The case was 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. On March 14, 2014, the Company's Motion to Dismiss was granted. The Plaintiffs replied their complaint, and the Company filed a Motion to Dismiss the First Amended Complaint. In May 2015, the Court dismissed the Plaintiffs' anti-kickback claim and remanded the remaining state law claims to the State Court of Fulton County. In July 2015, the Company filed a Motion to Dismiss these remaining claims. The Plaintiffs filed an opposition to the Company's Motion to Dismiss in August 2015. Also, the State of Georgia filed a brief as amicus curiae. The Company will vigorously defend the lawsuit.

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. In June 2015, Plaintiff's Motion for Class Certification was denied. The Plaintiff appealed the denial of Class Certification, and the Court of Appeal affirmed the denial of the Motion for Class Certification on January 20, 2017. The Company will vigorously defend the lawsuit.

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 lawsuit alleges that on or about February 21, 2012, the defendants violated the U.S. Telephone Consumer Protection Act (TCPA) by sending unsolicited facsimiles to Plaintiff and more than 39 other recipients without the recipients' prior express invitation or permission. 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 filed a notice of appeal. On May 3, 2016, the United States Court of Appeals for the Eighth Circuit issued its decision and order reversing the District Court's denial of class certification.

October 13, 2016, the case was removed to the United States District Court for the Southern District of California. The Company will vigorously defend the lawsuit.

Prior to the Company’s acquisition of Sequenom, between August 15, 2016, and August 24, 2016, six putative class-action lawsuits were filed on behalf of purported Sequenom stockholders (captioned Malkoff v. Sequenom, Inc., et al., No. 16-cv-02054-JAH-BLM, Gupta v. Sequenom, Inc., et al., No. 16-cv-02084-JAH-KSC, Fruchter v. Sequenom, Inc., et al., No. 16-cv-02101-WQH-KSC, Asiatsrade Development Ltd. v. Sequenom, Inc., et al., No. 16-cv-02113-AJB-JMA, Nunes v. Sequenom, Inc., et al., No. 16-cv-02128-AJB-MDD, and Cusumano v. Sequenom, Inc., et al., No. 16-cv-02134-LAB-JMA) in the United States District Court for the Southern District of California challenging the acquisition transaction. The complaints asserted claims against Sequenom and members of its Board of Directors (the Individual Defendants). The Nunes action also named the Company and Savoy Acquisition Corp. (Savoy), a wholly owned subsidiary of the Company, as defendants. The complaints alleged that the defendants violated Sections 14(e), 14(d)(4) and 20 of the Securities Exchange Act of 1934 by failing to disclose certain allegedly material information. In addition, the complaints in the Malkoff action, Asiatsrade action, and Cusumano action alleged that the Individual Defendants breached their fiduciary duties to Sequenom shareholders. The actions sought, among other things, injunctive relief enjoining the merger. On August 30, 2016, the parties entered into a Memorandum of Understanding (MOU) in each of the above-referenced actions. In connection with the settlement, Sequenom agreed to make certain additional disclosures to its stockholders. In September 6, 2016, the Court entered an order consolidating for all pre-trial purposes the six individual actions described above under the caption In re Sequenom, Inc. Shareholder Litig., Lead Case No. 16-cv-02054-JAH-BLM, and designating the complaint from the Malkoff action as the operative complaint for the consolidated action. On November 11, 2016, two competing motions were filed by two separate stockholders (James Reilly and Shikha Gupta) seeking appointment as lead plaintiff under the terms of the Private Securities Litigation Reform Act of 1995. On January 12, 2017 the Court entered an order declaring Mr. Reilly the presumptive lead plaintiff, but denying Mr. Reilly’s request for immediate approval as lead plaintiff. The Company is awaiting the Court’s appointment of a permanent lead plaintiff. The parties agree that the MOU has been terminated and are awaiting further direction from the Court as to how the litigation will proceed.

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, 2016, the Company had provided letters of credit aggregating approximately $54.5, 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, 2016 are as follows:

<table><tr><td></td><td>Operating</td></tr><tr><td>2017</td><td>$ 189.5</td></tr><tr><td>2018</td><td>140.5</td></tr><tr><td>2019</td><td>96.0</td></tr><tr><td>2020</td><td>55.3</td></tr><tr><td>2021</td><td>85.0</td></tr><tr><td>Thereafter</td><td>115.3</td></tr><tr><td>Total minimum lease payments</td><td>681.6</td></tr><tr><td>Less:</td><td></td></tr><tr><td>Amounts included in restructuring and acquisition related accruals</td><td>(41.6)</td></tr><tr><td>Non-cancelable sub-lease income</td><td>(0.4)</td></tr><tr><td>Total minimum operating lease payments</td><td>$ 639.6</td></tr></table>

Rental expense, which includes rent for real estate, equipment and automobiles under operating leases, amounted to $291.2, $287.1 and $235.7 for the years ended December 31, 2016, 2015 and 2014, respectively.

## 16. PENSION AND POSTRETIREMENT PLANS

## Pension Plans

The Company has a defined benefit retirement plan (Company Plan) and a nonqualified supplemental retirement plan (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 (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

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

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 pre-Acquisition employees. Prior to 2010, Company contributions to the plan were based on a percentage of employee contributions. From 2011, the Company made non-elective and discretionary contributions to the plan. In 2016, 2015, and 2014, non-elective and discretionary contributions were $56.0, $43.3 and $51.6, respectively. As a result of the Acquisition, the Company also incurred expense of $37.8 for the Covance 401K Plan during the year ended December 31, 2015. Under the Covance 401K Plan, which is available on a voluntary basis to substantially all U.S. Covance employees, the Company matches employee contributions up to a maximum Company contribution of 4.5%.

In addition, the Company Plan covers substantially all employees employed 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 $10.8, $9.5 and $12.4 in 2016, 2015 and 2014, 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 $15.3 in 2017. 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 2017, 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 $17.4 to the Company Plan and the PEP during 2017.

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

<table><tr><td rowspan="2"></td><td colspan="4">Year ended December 31,</td></tr><tr><td>2016</td><td>2015</td><td>2014</td><td></td></tr><tr><td>Service cost for benefits earned</td><td>$ 4.9</td><td>$ 3.9</td><td>$ 3.4</td><td></td></tr><tr><td>Interest cost on benefit obligation</td><td>15.5</td><td>15.1</td><td>16.4</td><td></td></tr><tr><td>Expected return on plan assets</td><td>(16.7)</td><td>(18.3)</td><td>(18.3)</td><td></td></tr><tr><td>Net amortization and deferral</td><td>11.2</td><td>11.3</td><td>6.6</td><td></td></tr><tr><td>Defined benefit plan costs</td><td>$ 14.9</td><td>$ 12.0</td><td>$ 8.1</td><td></td></tr></table>

Amounts included in accumulated other comprehensive earnings consist of unamortized net loss of $139.1. The accumulated other comprehensive earnings that are expected to be recognized as components of the defined benefit plan costs during 2017 are $11.2 related to amortization of the net loss.

A summary of the changes in the projected benefit obligations of the Company Plan and the PEP are summarized as follows:

<table><tr><td></td><td>2016</td><td>2015</td></tr><tr><td>Balance at January 1</td><td>$ 363.1</td><td>$ 388.6</td></tr><tr><td>Service cost</td><td>4.9</td><td>3.9</td></tr><tr><td>Interest cost</td><td>15.5</td><td>15.1</td></tr><tr><td>Actuarial loss (gain)</td><td>12.1</td><td>(15.4)</td></tr><tr><td>Benefits and administrative expenses paid</td><td>(29.1)</td><td>(29.1)</td></tr><tr><td>Balance at December 31</td><td>$ 366.5</td><td>$ 363.1</td></tr></table>

The Accumulated Benefit Obligation was $366.5 and $363.1 at December 31, 2016 and 2015, respectively.

A summary of the changes in the fair value of plan assets follows:

<table><tr><td></td><td>2016</td><td>2015</td></tr><tr><td>Fair value of plan assets at beginning of year</td><td>$ 250.6</td><td>$ 269.1</td></tr><tr><td>Actual return on plan assets</td><td>13.6</td><td>(0.3)</td></tr><tr><td>Employer contributions</td><td>12.4</td><td>10.9</td></tr><tr><td>Benefits and administrative expenses paid</td><td>(29.1)</td><td>(29.1)</td></tr><tr><td>Fair value of plan assets at end of year</td><td>$ 247.5</td><td>$ 250.6</td></tr></table>

The Company also updated the mortality assumption to the RP-2014 Mortality Tables in 2016 which decreased 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, 43% fixed income securities and 7% 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>5.15%</td></tr><tr><td>Fixed income securities</td><td>43.0%</td><td>1.3%</td></tr><tr><td>Other assets</td><td>7.0%</td><td>0.3%</td></tr></table>

The accumulated benefit obligation for the U.K. Plans and the German Plan was $235.8 and $25.4 at December 31, 2016, respectively. The accumulated benefit obligation for the U.K. Plans and the German Plan was $215.1 and $20.6 at December 31, 2015, respectively.

The amounts recognized in accumulated other comprehensive income for the year ended December 31, 2016 and December 31, 2015 is as follows:

There is $0.7 and $0.0 net actuarial loss for the U.K. Plans and German Plan, respectively required to be amortized from accumulated other comprehensive income into net periodic pension cost in 2017.

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

<table><tr><td>Equity securities</td><td>60.0% to 70.0%</td></tr><tr><td>Debt securities</td><td>10.0% to 15.0%</td></tr><tr><td>Annuities</td><td>10.0% to 20.0%</td></tr><tr><td>Real estate</td><td>—% to 10.0%</td></tr><tr><td>Other</td><td>—% to 5.0%</td></tr></table>

The weighted average asset allocation of the U.K. Plans as of December 31, 2016 by asset category is as follows:

<table><tr><td></td><td>December 31, 2016</td></tr><tr><td>Equity securities</td><td>70.0%</td></tr><tr><td>Debt securities</td><td>13.0%</td></tr><tr><td>Annuities</td><td>13.0%</td></tr><tr><td>Real estate</td><td>4.0%</td></tr></table>

Investments are made in pooled investment funds. Pooled investment fund managers are regulated by the Financial Conduct Authority in the U.K. and operate under terms which contain restrictions on the way in which the portfolios are managed and

require the managers to ensure that suitable internal operating procedures are in place. The trustees have set performance objectives for each fund manager and routinely monitor and assess the managers' performance against such objectives. Annuities represent annuity buy-in insurance policies purchased by the plan trustees from large, financially sound insurers. The cash flows from the annuities are intended to match the plan's obligations to specific groups of participants, typically those participants currently receiving benefits.

The fair value of the Company’s U.K. Plans' assets as of December 31, 2016 and December 31, 2015, by asset category, are as follows:

<table><tr><td rowspan="3">Asset Category</td><td rowspan="3">December 31, 2016</td><td colspan="5">Fair Value Measurements as of December 31, 2016</td></tr><tr><td colspan="4">Using Fair Value Hierarchy</td><td rowspan="2">Level 3</td></tr><tr><td>Level 1</td><td>Level 2</td><td>Level 3</td><td></td></tr><tr><td>Cash</td><td>$ 0.9</td><td>$ 0.9</td><td>$ —</td><td>$ —</td><td></td><td></td></tr><tr><td>Mutual funds (a)</td><td>202.5</td><td>—</td><td>202.5</td><td>—</td><td></td><td></td></tr><tr><td>Annuities (b)</td><td>29.8</td><td>—</td><td>—</td><td>—</td><td>29.8</td><td></td></tr><tr><td>Total fair value of the Company Plan’s assets</td><td>$ 233.2</td><td>$ 0.9</td><td>$ 202.5</td><td>$ 29.8</td><td></td><td></td></tr></table>

a) Mutual funds represent pooled investment vehicles offered by investment managers, which are generally comprised of investments in equities, bonds, property and cash. The plans’ trustees hold units in these funds, the value of which is determined by the number of units held multiplied by the unit price calculated by the investment managers. That unit price is derived based on the market value of the securities that comprise the fund, which are determined by quoted prices in active markets. No element of the valuation is based on inputs made by the plans’ trustees.

b) Annuities represent annuity buy-in insurance policies, whereby the insurer pays the pension payments for the lifetime of the members covered. The annuities are assets of the plan and payments from the insurer are made to the plans' trustees, who then use those proceeds to pay the pensioners. The cash flows from the annuities are intended to effectively match the payments to the pensioners covered by the policy. As such, these assets are valued actuarially based upon the value of the liabilities with which they are associated. As the valuation of these assets is judgmental, and there are no observable inputs associated with the valuation, these assets are classified as Level 3 in the fair value hierarchy.

Expected future benefit payments are as follows:

<table><tr><td></td><td>U.K. Plans</td><td>German Plan</td></tr><tr><td>2017</td><td>$ 4.1</td><td>$ 0.2</td></tr><tr><td>2018</td><td>4.1</td><td>0.2</td></tr><tr><td>2019</td><td>4.8</td><td>0.3</td></tr><tr><td>2020</td><td>5.1</td><td>0.5</td></tr><tr><td>2021</td><td>5.4</td><td>0.5</td></tr><tr><td>Years 2021-2026</td><td>37.5</td><td>3.0</td></tr></table>

## Post-employment retiree health and welfare plan

As a result of the Acquisition, the Company sponsors a post-employment retiree health and welfare plan for the benefit of eligible employees at certain U.S. subsidiaries who retire after satisfying service and age requirements. This plan is funded on a pay-as-you-go basis and the cost of providing these benefits is shared with the retirees. The net periodic post-retirement benefit cost for the year ended December 31, 2016 and December 31, 2015 was $(2.0) and $0.2, respectively, and the pension benefit obligation as of the Acquisition date was $6.3.

The components of net periodic post-retirement benefit cost for 2016 are as follows:



# 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>Year Ended December 31, 2016</td><td>Year Ended December 31, 2015</td></tr><tr><td>Interest cost</td><td>$ —</td><td>$ 0.2</td></tr><tr><td>Actuarial gain</td><td>(0.1)</td><td>—</td></tr><tr><td>Prior service credit</td><td>(1.9)</td><td>—</td></tr><tr><td>Net periodic post-retirement benefit cost</td><td>$ (2.0)</td><td>$ 0.2</td></tr><tr><td colspan="3">Assumptions used to determine net periodic post-retirement benefit cost:</td></tr><tr><td>Discount rate</td><td>4.2%</td><td>3.8%</td></tr><tr><td>Healthcare cost trend rate</td><td>7.0%</td><td>6.5%</td></tr></table>

The change in the projected post-retirement benefit obligation, the funded status of the plan and the reconciliation of such funded status to the amounts reported in the consolidated balance sheets as of December 31, 2016 and December 31, 2015 is as follows:

<table><tr><td></td><td>2016</td><td>2015</td></tr><tr><td>Balance at beginning of year</td><td>$ 5.2</td><td>$ 6.3</td></tr><tr><td>Interest cost</td><td>—</td><td>0.2</td></tr><tr><td>Participant contributions</td><td>0.7</td><td>0.8</td></tr><tr><td>Actuarial gain</td><td>0.1</td><td>(0.7)</td></tr><tr><td>Benefits paid</td><td>(1.3)</td><td>(1.4)</td></tr><tr><td>Plan amendments</td><td>(3.9)</td><td>—</td></tr><tr><td>Balance at end of year</td><td>$ 0.8</td><td>$ 5.2</td></tr><tr><td></td><td>2016</td><td>2015</td></tr><tr><td>Funded status</td><td>$ 0.8</td><td>$ 5.2</td></tr><tr><td>Recorded as:</td><td></td><td></td></tr><tr><td>Accrued expenses and other</td><td>$ 0.1</td><td>$ 0.6</td></tr><tr><td>Other liabilities</td><td>0.7</td><td>4.6</td></tr><tr><td></td><td>$ 0.8</td><td>$ 5.2</td></tr></table>

The amounts recognized in accumulated other comprehensive income as of December 31, 2016 are as follows:

<table><tr><td></td><td>Year Ended December 31, 2016</td><td>Year Ended December 31, 2015</td></tr><tr><td>Net actuarial gain</td><td>$ (2.6)</td><td>$ (0.7)</td></tr><tr><td>Less: Deferred tax benefit</td><td>0.9</td><td>0.3</td></tr><tr><td>Accumulated other comprehensive income impact</td><td>$ (1.7)</td><td>$ (0.4)</td></tr><tr><td colspan="3">Assumptions used to determine benefit obligation:</td></tr><tr><td>Discount rate</td><td>4.1%</td><td>4.2%</td></tr><tr><td>Healthcare cost trend rate</td><td>6.7%</td><td>7.0%</td></tr></table>

A one percentage point (1%) increase or decrease in the assumed healthcare cost trend rate would not impact the net service and interest cost components of the net periodic post-retirement benefit cost or the post-retirement benefit obligation since future increases in plan costs are paid by participant contributions. The Company expects to contribute $0.1 to the post-employment retiree health and welfare plan in 2017.

Expected future gross benefit payments are as follows:

<table><tr><td>2017</td><td>$ 0.1</td></tr><tr><td>2018</td><td>0.1</td></tr><tr><td>2019</td><td>0.1</td></tr><tr><td>2020</td><td>0.1</td></tr><tr><td>2021</td><td>0.1</td></tr><tr><td>2022 and thereafter</td><td>0.2</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:



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

<table><tr><td rowspan="2"></td><td colspan="4">Year ended December 31,</td></tr><tr><td>2016</td><td>2015</td><td>2014</td><td></td></tr><tr><td>Service cost for benefits earned</td><td>$ —</td><td>$ 0.1</td><td>$ 0.2</td><td></td></tr><tr><td>Interest cost on benefit obligation</td><td>0.3</td><td>1.0</td><td>1.8</td><td></td></tr><tr><td>Net amortization and deferral</td><td>(15.9)</td><td>(10.4)</td><td>(7.9)</td><td></td></tr><tr><td>Post-retirement medical plan costs</td><td>$ (15.6)</td><td>$ (9.3)</td><td>$ (5.9)</td><td></td></tr></table>

Amounts included in accumulated other comprehensive earnings consist of unamortized net loss of $6.9. The accumulated other comprehensive earnings that are expected to be recognized as components of the post-retirement medical plan costs during 2017 are $6.9 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 rowspan="2">Balance at January 1</td><td colspan="2">2016</td><td colspan="2">2015</td></tr><tr><td>$ 21.4</td><td>$ 28.9</td><td></td><td></td></tr><tr><td>Service cost for benefits earned</td><td>—</td><td></td><td>0.1</td><td></td></tr><tr><td>Interest cost on benefit obligation</td><td>0.3</td><td></td><td>1.0</td><td></td></tr><tr><td>Actuarial loss</td><td>(0.2)</td><td></td><td>(3.5)</td><td></td></tr><tr><td>Benefits paid</td><td>(1.3)</td><td></td><td>(1.8)</td><td></td></tr><tr><td>Plan amendment</td><td>(13.4)</td><td></td><td>(3.3)</td><td></td></tr><tr><td>Balance at December 31</td><td>$ 6.8</td><td>$ 21.4</td><td></td><td></td></tr><tr><td colspan="5"></td></tr><tr><td>Recorded as:</td><td></td><td></td><td></td><td></td></tr><tr><td>Accrued expenses and other</td><td>$ 1.0</td><td>$ 1.8</td><td></td><td></td></tr><tr><td>Other liabilities</td><td>5.8</td><td></td><td>19.6</td><td></td></tr><tr><td></td><td>$ 6.8</td><td>$ 21.4</td><td></td><td></td></tr></table>

The weighted-average discount rates used in the calculation of the accumulated post-retirement benefit obligation were 3.8% and 4.4% as of December 31, 2016 and 2015, respectively. The healthcare cost trend rate was removed due to the expectation of future funding to be at the same level as the previous year's funding.

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>2017</td><td>$ 1.0</td></tr><tr><td>2018</td><td>0.9</td></tr><tr><td>2019</td><td>0.8</td></tr><tr><td>2020</td><td>0.7</td></tr><tr><td>2021</td><td>0.6</td></tr><tr><td>Years 2022 and thereafter</td><td>2.2</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 U.S. 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 $54.2 and $46.4 at December 31, 2016 and 2015, 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.

## 17. FAIR VALUE MEASUREMENTS

The Company’s population of financial assets and liabilities subject to fair value measurements as of December 31, 2016 and 2015 were as follows:

The noncontrolling interest put is valued at its contractually determined value, which approximates fair value. During the year ended December 31, 2016, the carrying value of the noncontrolling interest put increased by $0.4 consisting of a $0.1 increase in the contractually determined value and a $0.3 increase 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.

Contingent accrued earn-out business acquisition consideration liabilities for which fair values are measured as Level 3 instruments. These contingent consideration liabilities were recorded at fair value on the acquisition date and are remeasured quarterly based on the then assessed fair value and adjusted if necessary. The increases or decreases in the fair value of contingent consideration payable can result from changes in anticipated revenue levels and changes in assumed discount periods and rates. As the fair value measure is based on significant inputs that are not observable in the market, they are categorized as Level 3.

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 $79.3 and $177.1 as of December 31, 2016 and 2015, respectively. The fair market value of the senior notes, based on market pricing, was approximately $5,254.5 and $5,457.4 as of December 31, 2016 and 2015, 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.

## 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



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

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 $14.6 at December 31, 2016. 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.

## 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 S&P’s Ratings Services is BB- or lower.

The Company believes these embedded derivatives had no fair value at December 31, 2016 and 2015. These embedded derivatives also had no impact on the consolidated statements of operations for the years ended December 31, 2016, 2015 and 2014.

## Derivatives Instruments

The Company periodically enters into foreign currency forward contracts, which are recognized as assets or liabilities at their fair value. These contracts do not qualify for hedge accounting and the changes in fair value are recorded directly to earnings. The contracts are short-term in nature and the fair value of these contracts is based on market prices for comparable contracts. The fair value of these contracts is not significant as of December 31, 2016.

## 20. BUSINESS SEGMENT INFORMATION

The following table is a summary of segment information for the years ended December 31, 2016, 2015, and 2014. The “management approach” has been used to present the following segment information. This approach is based upon the way the management of the Company organizes segments within an enterprise for making operating decisions and assessing performance. Financial information is reported on the basis that it is used internally by the chief operating decision maker (CODM) for evaluating segment performance and deciding how to allocate resources to segments. The Company’s chief executive officer has been identified as the CODM.

Prior to the first quarter of 2015, the CODM managed the operating results of the Company as two segments: commercial laboratory diagnostics and other. In connection with the Acquisition, the Company changed its operating segments to align with how the CODM evaluates financial information used to allocate resources and assess performance of the Company following the Acquisition. The segment information presented in these financial statements has been conformed to present segments on this revised basis for all prior periods. Under the new organizational structure, the CODM manages the Company under two segments: LCD and CDD. LCD includes the Company's legacy LabCorp business, and the Company's nutritional chemistry and food safety business, which was previously part of Covance, but excludes LabCorp's legacy clinical trials testing business, which is now part of CDD. CDD includes Covance's legacy business, and LabCorp's legacy clinical trials testing business, but excludes Covance's nutritional chemistry and food safety business, which is now part of LCD.

Segment asset information is not presented because it is not used by the CODM at the segment level. Operating earnings (loss) of each segment represents net revenues less directly identifiable expenses to arrive at operating income for the segment. General management and administrative corporate expenses are included in general corporate expenses below.

In the fourth quarter of 2015, the Company refined its methodology for how it allocates corporate expenses between the segments, which impacted segment results and has been applied to prior periods for comparative purposes.

In the first quarter of 2016, the Company finalized measurement periods adjustments and incorrectly recorded them retrospectively to the interim periods in 2015. The final measurement period adjustment consisted of foreign cumulative translation adjustments related to the final allocation of goodwill and intangibles to the applicable international geographies which was completed in the first quarter of 2016. As a result, the amounts of Other comprehensive income before tax for the first, second and third quarters of 2015 were inappropriately recast for the foreign currency translation adjustments of $122.2, $ (115.6), and $104.7, respectively. The cumulative foreign currency adjustment should have been recorded in the first quarter of 2016 which would have reduced the foreign currency translation adjustment amount by $80.4.

The reported amounts of Other comprehensive loss before tax were $289.9), $149.0, $207.5), and $138.3 and should have been $167.7), $33.4, $102.8), and $57.9 for the first, second and third quarters of 2015 and the first quarter of 2016 respectively. The Company concluded that these errors were not material individually or in the aggregate to any of the periods impacted. However, the Company will correct the foreign currency errors in the interim Consolidated Statements of Comprehensive Earnings for each of the affected periods when presented again.
