INTRODUCTION

Quest Diagnostics Incorporated is the world's leading provider of diagnostic information services. We play a crucial role in the healthcare ecosystem, empowering people to take action to improve health outcomes. Derived from the world's largest database of clinical lab results, our diagnostic insights reveal new avenues to identify and treat disease, inspire healthy behaviors and improve health care management. In the right hands and with the right context, our diagnostic insights can inspire actions that transform lives.

Quest Diagnostics was incorporated in Delaware in 1990; its predecessor companies date back to 1967. We conduct business through our headquarters in Secaucus, New Jersey, and our laboratories, patient service centers, offices and other facilities around the United States and in selected locations outside the United States. Unless the context otherwise requires, the terms “Quest Diagnostics,” the “Company,” “we” and “our” mean Quest Diagnostics Incorporated and its consolidated subsidiaries.

Table of Contents

The patients we serve comprise approximately one-third of the adult population of the United States annually, and approximately one-half of the adult population in the United States over a three-year period. We estimate that annually we serve approximately half of the physicians and half of the hospitals in the United States.

During 2019, we generated net revenues of $7.7 billion. Additional financial information concerning Quest Diagnostics, including our consolidated subsidiaries and businesses, for each of the years ended December 31, 2019, 2018 and 2017 is included in the consolidated financial statements and notes thereto in “Financial Statements and Supplementary Data” in Part II, Item 8.

Our vision, aspirational goals and values are set forth below.

We believe that our vision, aspirational goals and strategy (discussed below) align very well with, and our strong value proposition supports, the triple aim of healthcare: improving medical quality and the patient experience while reducing the cost of care.

OUR STRATEGY

We have a two-point business strategy, reviewed by our Board of Directors, to achieve our vision and our goals.

Table of Contents

Our strategy to accelerate revenue growth is based on the Company’s portfolio of services.

Table of Contents

We have identified the following five approaches to accelerate growth.

Approaches to Accelerate Growth (Table 2)

1. Delivering a compound annual revenue growth rate of more than 2% through accretive, strategic acquisitions

Plus organic growth through:

2. Partnering with health plans, IDNs and other risk bearing entities

3. Offering the broadest access to diagnostic innovation

4. Being recognized as the consumer-friendly provider of choice of diagnostic information services

5. Supporting population health with data analytics and extended care services

1. Growing through acquisitions. We have maintained a strategy since November 2018 to grow revenue each year by more than 2% compound annual growth rate through accretive, strategic acquisitions. Our approach to acquisitions is discussed below under the heading Deliver disciplined capital deployment.

2. Partnering with health plans, IDNs and other risk bearing entities. To help accelerate growth, we focus on large opportunities to partner with outside entities. We strengthen our relationships with health plans and increase the volume of our services for their members by driving value with employers and providing strong value propositions for members and clinicians. This includes building an information platform to help health plans manage utilization and population health, and enhancing processes to help plans keep laboratory testing in network. Effective January 1, 2019, the Company established a long-term strategic partnership with UnitedHealthcare, including collaborating on a variety of value-based programs, became a preferred provider to Horizon Blue Cross Blue Shield of New Jersey for most products and became a participating provider to Blue Cross Blue Shield of Georgia. Effective July 1, 2019, the Company was selected to be one of only five lab companies named participants in the UnitedHealthcare Preferred Lab Network, meeting exceptional criteria for access, cost, data, quality and service.

We believe that the growing market challenges faced by IDNs, including continued price transparency, cost and utilization pressure, evolving healthcare payment models, capital needs, changing technology and limited resources, provides us with an opportunity to more effectively partner with them as they consider their laboratory testing strategy and will drive demand for our expertise. We have deployed a dedicated health systems team to strengthen our relationships with IDNs, including with respect to their reference testing. We provide reference testing for approximately 50% of hospitals in the U.S., and are the leading provider of this testing in the country. In 2019, we implemented new Professional Laboratory Services relationships with Catholic Health Services of Long Island and Regional Medical Center of Orangeburg, S.C.



Our industry-leading Professional Laboratory Services suite of solutions help IDNs build and execute their laboratory strategy, improve quality, reduce the cost of care and focus on core competencies.
Key Professional Laboratory Services Offerings (Table 3)

Joint venture	Reference testing, including advanced diagnostics
Outreach acquisition	Supply chain management and purchasing
Test menu optimization and spend consolidation	Blood utilization management

3. Offering the broadest access to diagnostic innovation. Our diagnostic solutions deliver high clinical value to the medical community nationwide. We create value through scientific and product innovation and solution delivery for major clinical opportunities. Starting with a clinical focus on a specific disease state or clinical problem, we take advantage of advanced technology for more precise, comprehensive and actionable information, and deliver the information to the medical community in a meaningful way. We make innovative diagnostic solutions available to community physicians through our connectivity solutions, operational footprint and by making complex results actionable. We plan to expand our innovative diagnostic solutions through research and development, as well as partnerships with academic institutions, other technology and healthcare leaders and public health agencies.

Consistent with that expectation, in January 2020 we announced that we increased our quarterly common stock cash dividend by approximately 6%, from $0.53 per common share to $0.56 per common share. This represents our ninth increase in the dividend since 2011. For many years, we have maintained a common stock repurchase program. Since the beginning of 2013, we have returned approximately $3.1 billion to stockholders through repurchases of our common stock. Our share repurchases, dividends and capital expenditures in each of the last five years are presented in Selected Historical Financial Data of Our Company beginning on page 52.

The Company's strategy includes generating growth through value-creating, strategically-aligned acquisitions using disciplined investment criteria. We screen potential acquisitions using guidelines that assess strategic fit and financial considerations, including value creation, return on invested capital and impact on our earnings. In 2019, we consummated the acquisition of certain assets of the clinical laboratory services business of Boyce & Bynum Pathology Laboratories, P.C. Our material acquisitions in each of the last three years are further discussed in Note 6 to the audited consolidated financial statements (Part II, Item 8 of this Report).

We will continue to invest in our business in a disciplined manner, including focusing on enhancing our solid foundation of strategic assets and capabilities, accelerating growth and driving operational excellence. Our near-term investments in growth are likely to focus on the strategies to accelerate growth set forth in table 2 above. Our near-term investments to drive operational excellence are likely to focus on improving the customer experience and gaining efficiency, systems standardization, digital enablement of our processes and footprint optimization.

We maintain relationships with advisers and consultants who are leaders in key fields of science and medicine. As the industry leader with the largest and broadest U.S. network, we believe we are the distribution channel of choice for developers of new solutions.

We seek innovations and solutions that help healthcare providers care for their patients through better testing for predisposition, screening, monitoring, diagnosis, prognosis and treatment choices, and that will reduce the overall cost of healthcare. We seek to develop innovations and solutions that help to determine a patient's genotype or gene expression profile relative to a particular disease and its potential therapies, because they can help healthcare providers to determine a patient's susceptibility to disease or to tailor medical care to an individual's needs - such as determining if a medication might be an optimum choice for a particular person, or tailoring the right dosage once the proper medicine is prescribed. We endeavor to improve test processes, including through increased automation. In addition, we aim to develop holistic solutions responsive to challenges that healthcare providers and patients face, by developing solutions of tests, information and services focused on specific clinical challenges, and taking advantage of the latest informatics capabilities. We also look for innovations and solutions that are less invasive than currently available options, to increase the choices that healthcare providers and patients have for the collection of diagnostic samples. We additionally seek innovation in the ways we bring solutions to customers, and in the customer experience, including enhanced services and end-to-end solutions for convenience and support. Further, we seek innovative solutions to other challenges related to diagnostics information services faced by IDNS, health plans and other health care market participants.

Collaboration

We believe that strategic relationships, including with healthcare providers, public health authorities, consumer-focused entities and others, can position us for growth at the center of healthcare and that healthcare companies that can partner effectively with others will be successful in the long term. We collaborate with partners that can help us to achieve our vision of empowering better health through diagnostic insights and have relationships across the spectrum of healthcare, including with world class healthcare and consumer-focused leaders, to foster important advances in healthcare, including in precision medicine and healthcare delivery. We plan to continue to pursue strategic relationships to help accelerate growth and drive operational excellence.

Diagnostic Information Services

Background - clinical testing. Clinical testing is an essential element in the delivery of healthcare services. Clinicians use clinical testing for predisposition, screening, monitoring, diagnosis, prognosis and treatment choices of diseases and other medical conditions. Clinical testing is generally categorized as clinical laboratory testing and anatomic pathology services. Anatomic pathology involves the diagnosis of cancer and other diseases and medical conditions through examination of tissue and cell samples taken from patients.

Clinical laboratory testing, which can be characterized as routine, non-routine or advanced, generally is performed on whole blood, serum, plasma and other body fluids, such as urine, and specimens such as microbiology samples. Clinical laboratory tests which can be performed by most clinical laboratories are considered routine. Routine testing measures various important bodily health parameters such as the functions of the kidney, heart, liver, thyroid and other organs. Commonly ordered routine tests include blood chemistries, urinalysis, allergy tests and complete blood cell counts. Non-routine tests may require professional “hands-on” attention from highly-skilled technical personnel, generally require more sophisticated informatics, technology, equipment or materials, may be performed less frequently than routine tests and may be reimbursed at higher levels than routine tests. It may not be practical, from a cost-effectiveness or infrastructure perspective, for many hospitals, IDNs, ACOs, commercial laboratories or physician office laboratories to develop and perform a broad menu of non-routine tests, or to perform low-volume non-routine testing in-house. Such tests generally are outsourced to a clinical testing laboratory which can perform these non-routine tests. Some non-routine tests are advanced. Advanced tests include procedures in the areas of molecular diagnostics (including next-generation sequencing), oncology, neurology, companion diagnostics and non-invasive pre-natal and other germline genetic testing.

Our services. We are the world's leading provider of diagnostic information services. We provide information and insights based on the industry-leading menu of routine, non-routine and advanced clinical testing and anatomic pathology testing, and other diagnostic information services. We have strong testing capabilities, including services for the predisposition, diagnosis, treatment and monitoring of cancers and other diseases, and offer advanced tests in many fields, including endocrinology, immunology, neurology and oncology. Increasingly, we are focused on providing solutions and insights to our customers, based on the testing that we perform, the data that we gather and our extensive medical, information and connectivity assets. We believe that offering services, solutions and insights based on a full range of tests, information assets and other capabilities strengthens our market offering, market position and reputation.

We offer the broadest access in the United States to clinical testing. We maintain a nationwide network of laboratories, including advanced laboratories (such as our world-renowned Quest Diagnostics Nichols Institute^®) as well as rapid response laboratories (smaller facilities where we can quickly perform an abbreviated menu of routine tests for customers that require rapid turnaround times).

THE CLINICAL TESTING INDUSTRY

Key Trends

The healthcare system in the United States is evolving; significant change is taking place in the system. We expect that the evolution of the healthcare industry will continue, and that industry change is likely to be extensive. There are a number of key trends that are having, and that we expect will continue to have, a significant impact on the diagnostic information services business in the United States and on our business. These trends, discussed in the table below, present both opportunities and risks. We believe that several of the trends, including consolidation, price transparency and consumerization, are favorable to our business.

Table of Contents

Because diagnostic information services is an essential healthcare service and because of the key trends discussed below, we believe that the industry will continue to grow over the long term. In addition, we believe that the clinical testing market continued with fundamental changes in 2019. First, we believe that PAMA-driven reimbursement pressure is negatively impacting access to care and hurting the clinical testing industry, and remains a catalyst for structural change in the market. Second, we believe that our expanded health plan network access and increased health plan focus on driving better value in laboratory testing services will reduce variation in spending on these services. Third, we believe that ongoing consumerization in healthcare, with increased cost being borne by consumers, is sharpening focus on price disparities. We believe that these changing market fundamentals will benefit low-cost, high-value providers like Quest and that we are well positioned to grow from the changing market conditions and benefit from the long-term growth expected in the industry.



Key Trends (Table 11)
PAMA-driven reimbursement pressure	Pursuant to PAMA, CMS promulgated revised reimbursement rates schedules for clinical laboratory testing services provided under Medicare for 2018, 2019 and 2020. Under the revised Medicare Clinical Laboratory Fee Schedule, reimbursement rates for many clinical laboratory tests were reduced in 2018 and 2019 and are scheduled to be reduced again by approximately 10% in 2020 (rates, and reductions, vary by test). PAMA calls for further revision of the Medicare Clinical Laboratory Fee Schedule for years after 2020, based on future surveys of market rates; reimbursement reduction from 2021-23 is capped by PAMA at 15% annually. In late 2019, the LAB Act became law. The LAB Act provides an opportunity for reforms to PAMA by delaying PAMA's next data collection and reporting period until January 1, 2021 and by ordering a study to determine ways to improve future collection of more representative market rate data under PAMA. The American Clinical Laboratory Association, of which the Company is a member, initiated a lawsuit charging that in implementing PAMA, CMS failed to follow a Congressional directive to implement a market-based laboratory payment system. The lawsuit is pending. Based on our discussions during 2019 with other lab testing providers, we believe that PAMA is negatively impacting participants in the laboratory testing industry generally, including hospitals as well as independent clinical laboratories. In addition, during 2019, the nation's largest provider of laboratory testing services to nursing homes, which provided testing to approximately 12,000 facilities in more than 35 states, filed for bankruptcy protection; press reports cited PAMA as a reason for the bankruptcy.
Health plans driving value in lab spending	Hospitals, which provide outreach testing and may encourage clinicians to send their outreach testing to the hospital's laboratory, historically were able to negotiate higher reimbursement rates with health plans than commercial clinical laboratories for comparable services. In addition, health plans generally reimburse non-participating laboratory testing providers at higher out-of-network rates. As we have expanded our health plan network access, we are finding increased interest among health plans in driving better value in spending for laboratory testing. Health plans increasingly are taking steps to encourage the movement of testing volume to high value, low cost providers like our Company, including by identifying preferred provider partners, plan design changes (e.g., zero-dollar out-of-pocket costs for members using preferred providers) and better aligning reimbursement rates for hospital-based providers and independent commercial laboratories. The UnitedHealthcare Preferred Lab Network, in which we were chosen to participate, is a recent example of a health plan taking these steps. Health plans also are increasingly adopting policies, practices and procedures based on requirements imposed by government payers such as Medicare and Medicaid. These policies, practices and procedures are subject to change, and may be changed without notice to us.
Consumerization	Consumers are our customers. Increasingly, consumers are engaged in their own healthcare, being empowered to understand and manage their healthcare. Consumers are taking increased interest in and responsibility for their healthcare, their expectations of healthcare providers are increasing and they are becoming more sophisticated regarding healthcare. Some patients are interested in ordering their own diagnostics tests, rather than relying upon a healthcare professional to order the tests. In addition, consumers often are bearing increased financial responsibility for their healthcare (e.g., high deductible health plans; rising deductibles). In our experience, consumers are more focused on transparency, ease of doing business and understanding diagnostics information services than they have been in the past. Consumers increasingly are demanding convenience; a superior and personalized experience relevant to their needs; and to be empowered to make their own healthcare decisions. In addition, consumers are seeking prompt, direct access to their test results. Increasingly, consumers are motivated to find high quality service providers with low prices, like our Company.

Prevention and wellness	We believe that the value of detection, prevention, wellness and personalized care is well recognized. Consumers, employers, ACOs, IDNs, health plans and government agencies increasingly focus on helping the healthy stay healthy, detecting symptoms among those at risk and providing preventive insight and care that helps avoid disease.
Medical innovation	Medical advances allow for more accurate and earlier diagnosis and treatment of diseases. Continuing advances in genomics and proteomics are expected to yield new, more sophisticated and specialized diagnostic tests. These advances also are spurring interest in and demand for precision medicine, which relies on diagnostic and prognostic testing and in which data information services and strategies are used to deliver the most effective healthcare to the right populations and individuals. Pharmacogenomic testing increasingly is used as a parameter to help speed drug approval processes and to better focus therapy based on patient and tumor-specific genetic markers. Demand also is growing toward comprehensive care management solutions that serve patients, payers and healthcare providers by improving clinical decision support and access to patient data, and by increasing patient participation in care management and population health management. There is increasing focus on access to patient data and data-driven insights.
Healthcare industry evolution	Clinicians, health plans, IDNs, ACOs, employers and others, have been consolidating, converging and diversifying. For example, an increased number of hospital systems are considering establishing or have established health insurance plans, and health insurance plans are considering providing or are providing healthcare services. In recent years, a leading provider of retail medical clinics and pharmacy benefits management services has acquired a leading health insurance provider, a leading health insurance provider has acquired a leading pharmacy benefits manager, and the corporate parent of a leading health insurance company provides a wide array of health care services through its non-insurance company subsidiaries. Health plans are entering agreements with other providers of healthcare services, including laboratory testing services providers, to partner on value-based approaches to delivering health care to populations. Consolidation is increasing pricing transparency and bargaining power, and may encourage internalization of clinical testing. Physicians frequently now are employed by hospital systems, IDNs, ACOs or large group practices integrated with healthcare systems, instead of organizing physician-owned practices, which is impacting the dynamics for whether clinical testing is performed in or outside of a hospital. Physicians and other clinicians also increasingly are being employed by health plans or their affiliates. Value-based reimbursement is contributing to changes in the healthcare system. ACOs and patient-centered medical homes have grown as a means to deliver patient care. Healthcare services increasingly are being provided by non-traditional providers (e.g., physician assistants), in non-traditional venues (e.g., retail medical clinics, urgent care centers) and using new technologies (e.g., telemedicine, digital pathology). In addition the ACA continues to result in changes in the way that some healthcare services are purchased and delivered in the United States. Hospitals and IDNs are under significant pressure, and are evolving.
Pricing transparency	There has been a trend toward greater pricing transparency in healthcare, including in the laboratory testing marketplace. Several states have taken action to foster greater pricing transparency in healthcare. For example, Massachusetts has launched a website to help consumers understand the wide variation in health care costs. In addition, in June 2019 the President issued an executive order on improving price and quality transparency in American healthcare, and later in 2019 federal government agencies unveiled regulations designed to increase price transparency in healthcare: proposed rules requiring group health plans and insurers to disclose cost-sharing information to consumers in advance of care being provided; and final rules requiring hospitals to disclose information on negotiated rates for consumers. Increased price transparency, combined with increased patient financial responsibility for medical care, is enhancing purchasing sophistication and changes in behavior in the healthcare marketplace. We believe that increased price transparency should benefit low cost, high value providers like our Company.

Competition	The diagnostic information services industry remains fragmented, is highly competitive and is subject to new competition. Competition is emerging from new technologies (e.g., digital pathology) and growing from non-traditional competitors. Increased hospital acquisitions of physician practices may enhance clinician ties to hospital-affiliated laboratories and may strengthen their competitive position. However, in light of other trends, including continued reimbursement pressure, hospitals may change their approach to providing clinical testing services. New industry entrants with extensive resources may make acquisitions or expand into our traditional areas of operations.
Healthcare utilization	Healthcare utilization in the United States has fluctuated based on a number of factors. These factors include, without limitation, the economy, healthcare benefits design, patients delaying medical care, and increased consumer financial responsibility for, interest in and control of their healthcare. The ACA contained provisions eliminating patient cost-sharing for preventative services, and additional provisions that we believe have increased the number of patients that have health insurance, including Medicaid, and thus better access to diagnostic testing.
Reimbursement pressure; affordability	There is a strong focus in the United States on controlling the overall cost of healthcare. Healthcare market participants, including governments, are focused on controlling costs. Examples of cost control approaches include reducing reimbursement for healthcare services, changing reimbursement for healthcare services (e.g., shift from fee for service to capitation), changing medical coverage policies (e.g., healthcare benefits design), denying coverage for services, requiring preauthorization of laboratory testing, requiring co-pays, introducing laboratory spend management utilities and payment and patient care innovations such as ACOs and patient-centered medical homes. CMS has set goals for value-based reimbursement to be achieved in Medicare. There is increased market activity regarding alternative payment models, including bundled payment models. The Health Transformation Alliance, a group of over 40 major U.S. companies, was formed to improve and reform the healthcare system in the United States. The rising cost of healthcare in the United States was a key driver for the formation of this alliance. In 2018, a trio of high profile U.S. corporations, citing rising health care costs, announced plans to reduce their workers' health care costs by forming a non-profit venture that would provide simplified, high-quality healthcare for their workers. While pressure to control healthcare costs poses a risk to our Company, it also creates opportunities, such as an opportunity for increased proper utilization of testing as an efficient means to manage the total cost of healthcare. We believe that it also creates greater opportunities for consolidation and gaining share for high value, low-cost providers, like our Company, as compared to other providers.
Legislative, regulatory and policy environment	Government oversight of and attention to the healthcare industry in the United States is significant and increasing; healthcare payment reform is a top issue. Legislation introduced in Congress would enable the FDA to regulate LDTs, in vitro diagnostics, software and other items used in the diagnosis of disease. If the legislation becomes law, the FDA could regulate diagnostic tests and components and platforms used as part of these tests. If the legislation becomes law, it could have a significant impact on the clinical laboratory testing industry, including regulating LDTs in new ways, while creating avenues of opportunity and competition regarding clinical laboratory testing. New competitors may enter the industry, and competition may come in new forms. The ACA has created significant uncertainty as healthcare markets react to changes. For example, more than half of the states have opted in to Medicaid expansion and employers may discontinue offering group health insurance to their employees, shifting more people to exchange products. Certain aspects of the ACA have been repealed, delayed or modified (e.g., the medical device excise tax). The scope and timing of any further legislation to repeal, amend, replace, or reform the rest of the ACA is uncertain, but if such legislation were to become law, it could have a significant impact on the U.S. healthcare system. In addition, uncertainty regarding the status of the ACA prior to any such repeal, amendment, replacement or reform could create uncertainty generally in the healthcare market. Several federal courts have recently issued determinations that portions of the ACA are unconstitutional; those rulings are not yet final. Uncertainty about court rulings regarding the ACA could add to uncertainty in the healthcare market.

Informatics; technology; privacy concerns	The increased availability of healthcare data, including data made available as a result of next generation DNA sequencing, and the increased ability to effectively analyze that data at population and patient levels, is impacting healthcare practices. It is anticipated that the increased use of data in healthcare, coupled with mobile healthcare IT solutions for doctors and patients, will help to improve patient outcomes and reduce overall healthcare costs. Informatics, including integrated diagnostic and decision support solutions, predictive analytics, use of population data and healthcare information technology, is spurring advances in precision medicine, including medical decision making and value, for populations and individuals. The increased focus on data and its use is increasing focus on maintaining the privacy of patient data. There is a need for technology solutions to harness these opportunities. In addition, new technology, social media and mobile technology are changing the way that healthcare markets interact with each other, and the expectations that they have about how services are provided, what services are provided, and other capabilities of healthcare market participants. These developments are creating new opportunities and new challenges and disrupting the healthcare environment. For example, digital pathology is an emerging technology that may change the practice of pathology. Information technology that includes self-learning or "artificial intelligence" features is growing and may impact the healthcare industry. Healthcare market participants, including pharmaceutical companies, health plans, clinicians, ACOs and IDNs, are striving to leverage interoperability, informatics and analytics to positively influence the health of patient populations while maintaining patient privacy.
Chronic diseases and conditions; gaps in care	We believe that the cost and challenges of identifying, treating and controlling chronic diseases and conditions such as diabetes and heart disease are now well recognized. As a result of multiple factors, including increased focus on population health management and pressure to reduce the systemic costs associated with such diseases and conditions, there is increased focus on better identifying and attempting to reduce or eliminate the gaps in care historically associated with these diseases and conditions. Healthcare market participants are developing new approaches for this purpose.
Healthcare services delivery	Healthcare delivery is moving out of hospitals, doctor offices and other traditional locations in which it had been provided. Care is increasingly being provided in new settings, such as out-patient, consumer-focused and home settings. For example, see the discussion of Emerging Retail Healthcare Providers in table 13. This dynamic offers new opportunities and challenges for healthcare providers and reflects not only efforts to take advantage of new technologies, but also the trends of consumerization and affordability, each of which are discussed above in this table.

The Value of Diagnostic Information Services

As noted in table 11, there is an increased focus on the affordability of healthcare. There also is increased focus on a disease-oriented approach to diagnostics, treatment and management. Healthcare providers, consumers and payers increasingly recognize the value of diagnostic information services as a means to improve health and reduce the overall cost of healthcare through early detection, prevention and treatment. Healthcare providers increasingly rely on diagnostic information services to help identify risk for a disease, to detect the symptoms of disease earlier, to aid in the choice of therapeutic regimen, to monitor patient compliance and to evaluate treatment results. Table 12 highlights how diagnostic information services contribute to improving care and reducing health care costs.

Reducing Healthcare Costs and Improving Care (Table 12)

• Identifying patients at risk for disease before they require urgent care, hospital treatment or expensive therapies

• Helping clinicians to target the right medicines for the right patients at the right time

• Identifying treatment-related side effects

• Early assessment of the efficacy of a therapy, enabling changes or discontinuation of ineffective therapies

• Enabling population health management by utilizing diagnostic information, identifying gaps in care and delivering targeted solutions to individuals who need care

• Identification and proactive management of individuals at risk for developing chronic diseases, to decrease progression and associated costs and morbidity

• Providing telemedicine services along with laboratory testing to help individuals interpret and obtain appropriate advice and referrals into needed care

Customers

We provide diagnostic information services to a broad range of customers, including those discussed below. As discussed in table 11 above, customers are consolidating, converging and diversifying. In many cases, the customer that orders our services is not responsible for paying for these services. Depending on the billing arrangement and applicable law, the payer may be the patient or a third party, such as a health plan, Medicare or a Medicaid program. Increasingly, patients are bearing greater responsibility for some portion of the payment for the services we provide to them, even if a third party is primarily responsible for payment.



Customers (Table 13)
Health plans including managed care organizations and other health insurance providers	These customers typically reimburse us as a contracted (or out-of-network) provider on behalf of their members. In certain locations, health plans may delegate to IPAs or other alternative delivery systems (e.g., physician hospital organizations, ACOs, patient-centered medical homes) the ability to negotiate for diagnostic information services on behalf of certain members. Health plans and IPAs often require that diagnostic information services providers accept discounted fee structures or assume all or a portion of the financial risk associated with providing such services through capitated payment arrangements. Under capitated payment arrangements, we provide services at a predetermined monthly reimbursement rate for each covered member, generally regardless of the number or cost of services provided by us. Under some capitated programs, we may provide certain services on a negotiated fee-for-service basis. Reimbursement under programs that do not provide for capitated payments is typically negotiated on a fee-for-service basis. Reimbursement from our five largest health plans totaled approximately 20%, and no one health plan accounted for 10%, of our consolidated net revenues in 2019. Health plans typically negotiate directly or indirectly with a number of diagnostic information services providers, and represent approximately one-half of our total clinical testing volumes and approximately 40% of our net revenues from diagnostic information services. There has been a trend of consolidation among health plans. Some health plans also have narrowed their provider networks. We are also sometimes a member of a “complementary network.” A complementary network generally is a set of contractual arrangements that a third party will maintain with various providers that provide discounted fees for the benefit of its customers. A member of a health plan may choose to access a non-contracted provider that is a member of a complementary network; if so, the provider will be reimbursed at a rate negotiated by the complementary network. We offer to health plans services and programs that leverage our Company's expertise and resources, including our superior access, extensive test menu, medical staff, data, information technology solutions, and wellness and population health management capabilities. Effective January 1, 2019, Quest Diagnostics became a participating provider to UnitedHealthCare, Blue Cross Blue Shield of Georgia and Horizon Blue Cross and Blue Shield in New Jersey. With access to an additional approximately 43 million insured lives, the Company now has access to approximately 90% of the insured lives in the U.S., including very strong access in key high-population states, its best access to health plan members in over a decade. We believe that this improved access increases our attractiveness to other customer groups, including clinicians, patients and employers.
Clinicians	Clinicians, including primary care physicians, specialists and physician assistants, requiring diagnostic information services for patients are the primary referral source for our services when patients choose their diagnostic information services provider. In recent years, there has been a marked increase in the number of physician practices owned by IDNs and hospital systems. There also has been a notable increase in some branches of medicine of the establishment of very large "rolled-up" specialty physician practice groups. Hospitals that own physician practices may require the practices to refer outreach testing to the hospital's affiliated laboratory. Large specialty physician groups may encourage their members to refer testing to other members of the group. In each case, referrals to independent diagnostic services providers may be reduced. Clinicians determine which laboratory to recommend or use based on a variety of factors, including those set forth in table 14.

Table of Contents



Hospitals	We believe that we are the industry's leader in servicing hospitals. We provide services to hospitals throughout the United States, including advanced testing services, in some cases helping manage their laboratories and serving as the medical directors of the hospital's histology or clinical laboratory, including through our Professional Laboratory Services offerings (our industry-leading Professional Lab Services offering is discussed in Table 3 above). Hospitals generally maintain an on-site laboratory to perform the significant majority of clinical testing for their patients (inpatients and outpatients) and refer certain testing to outside service providers, which typically charge the hospitals on a negotiated fee-for-service basis. Fee schedules for hospital reference testing services often are negotiated on behalf of hospitals by group purchasing organizations. We also have joint venture arrangements with leading hospitals or IDNs in several metropolitan areas. These joint venture arrangements, which provide diagnostic information services for affiliated hospitals as well as for unaffiliated clinicians and other local healthcare providers, serve as our principal facilities in their service areas. Typically, we have either a majority ownership interest in, or day-to-day management responsibilities for, our joint venture relationships. In light of continued pressure to reduce systemic healthcare costs, hospitals may change their approach to providing clinical testing services, including by insourcing tests, seeking ways to improve profitability or to better utilize their laboratory capacity. We believe that our combination of services positions us to be an attractive partner for hospitals, offering a full range of strategic relationships.
ACOs and IDNs	An ACO is a network of providers and facilities that share financial risk in providing or arranging for the provision of healthcare. An IDN is a network of providers and facilities working together in providing or arranging for the provision of healthcare. ACOs and IDNs have increased in number; their impact on the provision of healthcare services to date has varied. ACOs and IDNs may exercise operational and financial control over providers across the continuum of care, and may function as a payer. Thus, they may be able to manage the health of a population group within a defined geography, and also may be able to influence the cost and quality of healthcare delivery, for example through owned entities and through ancillary services. ACOs may be encouraged to consider exclusive arrangements with healthcare providers that become part of the ACO, or to limit service providers to the ACO, since members of the ACO share financial risk. We are actively engaging with ACOs and IDNs to demonstrate the value of our services.
Employers	Employers use tests for drugs of abuse to determine an individual's employability and his or her “fitness for duty.” Companies with high employee turnover, safety conscious environments or regulatory testing requirements provide the highest volumes of testing. Factors such as the general economy and job market can impact the utilization of drugs-of-abuse testing. Employers also are investing in health and wellness services. We meet their needs by providing nationwide access to our customizable wellness services (discussed above at page 11), directly and through health plan and health improvement providers. These services help employers, employees and others manage healthcare costs and capitalize on trends in personalized health. We seek to grow our employer business through offering new and innovative programs to help them with their goals of (1) maintaining a safe and productive workplace, (2) improving healthcare for employees and (3) lowering healthcare costs for employees and employers.
Consumers	We are well positioned to provide information and insights to patients to help them take actions to improve their healthcare. The changing expectations of patients about their healthcare and their healthcare transactions are influencing our services and the way we provide them. See the discussions of our consumer strategy at page 5 and consumerization above in table 11.
Emerging Retail Healthcare Providers	In recent years, as the healthcare sector changes, retail providers of healthcare services have emerged and are growing. These providers include "big-box" retailers, pharmacy chains, supermarkets, urgent care centers and Internet-based service providers. We are taking advantage of opportunities to work with these providers, not only to offer new access points for our services (e.g., our collaboration with Safeway), but also to grow our business by expanding our service offerings (e.g., our joint venture with Walmart). See the discussion of our consumer strategy at page 5.

Table of Contents



Government Agencies	We provide services on a fee-for-service basis to federal, state and local governmental agencies. Historically, most Medicare and Medicaid beneficiaries were covered under the traditional Medicare and Medicaid programs administered by the federal government. Over the last several years, the federal government has expanded its contracts with private health insurance plans for Medicare beneficiaries and has encouraged such beneficiaries to switch from the traditional programs to the private programs, called “Medicare Advantage” programs. There has been growth of health insurance providers offering Medicare Advantage programs and of beneficiary enrollment in these programs. States also have mandated that Medicaid beneficiaries enroll in private managed care arrangements.
Pharmaceutical companies	We have expertise with laboratory developed tests for companion and complementary diagnostics, and offer an array of assets and services to support the development of companion diagnostics, including our robust data set and patient services network. We also offer Quest Clinical Trials Connect,^TM to help accelerate clinical trials (and thus the speed of drugs to market) through better patient recruitment, involvement and management, and improved physician outreach.
Other Laboratories	We provide services on a fee-for-service basis to other commercial clinical laboratories.

Competition. While there has been significant consolidation in the diagnostic information services industry in recent years, our industry remains fragmented and highly competitive. We primarily compete with three types of clinical testing providers: commercial clinical laboratories, hospital-affiliated laboratories and physician-office laboratories. Our largest commercial clinical laboratory competitor is Laboratory Corporation of America Holdings, Inc. In addition, we compete with many smaller regional and local commercial clinical laboratories and specialized advanced laboratories. In anatomic pathology, we compete with anatomic pathology practices, including those in academic institutions and large physician group practices, and providers of emerging digital pathology solutions. There also has been a trend among specialty physician practices to establish their own histology laboratory capabilities and/or bring pathologists into their practices, thereby reducing referrals from these practices and increasing the competitive position of these practices.



Healthcare providers consider a number of factors when selecting a diagnostic information services provider.
Potential Factors Considered When Selecting a Diagnostic Information Services Provider (Table 14)
• Service capability and quality	• Reputation in the medical community
• Accuracy, timeliness and consistency in reporting test results	• Healthcare information technology solutions, including connectivity options
• Access to medical/scientific thought leaders for consultation	• Patient access, including the number, convenience and geographic coverage of patient service centers
• Patient insurance coverage and experience	• Ability to develop new and useful tests and services
• Number and type of tests performed	• Qualifications of its staff
• Pricing and overall value	• Provider office workflow
• Real time payment determination	• Capabilities to support population health initiatives

We believe that providing the most attractive service offering in the industry, including the most comprehensive test menu, innovative test offerings, a positive customer experience, a staff including medical and scientific experts, strong quality, unparalleled access and distribution, and data-powered integrated information technology solutions provide us with a competitive advantage.

We believe that large diagnostic information services providers have a competitive advantage due to their large networks and lower cost structures, including as a result of PAMA. These advantages should enable larger providers to more effectively serve customers. In addition, we believe that consolidation in the diagnostic information services industry will continue. However, a significant portion of clinical testing is likely to continue to be performed by hospitals, which generally have affiliations with community clinicians and may have more, or more convenient, locations in a market. As a result, we compete against hospital-affiliated laboratories primarily on the basis of service capability, quality and pricing. In addition, market activity may increase the competitive environment. For example, hospital ownership of physician practices may enhance the ties of the clinicians to hospital-affiliated laboratories, enhancing the competitive position of hospital-affiliated

Table of Contents

laboratories. The formation of ACOs and IDNs, and their approach to contracts with healthcare providers, in addition to the impact of informatics, also may impact competition to provide diagnostic information services.

The diagnostic information services industry is faced with changing technology, new product introductions and new service offerings. Competitors may compete using advanced technology, including technology that enables more convenient or cost-effective testing. Digital pathology, still in an emerging state, is an example of this. Competitors also may compete on the basis of new service offerings. Competitors also may offer testing to be performed outside of a commercial clinical laboratory, such as (1) point-of-care testing that can be performed by physicians in their offices; (2) testing that can be performed by hospitals in their own laboratories; and (3) home testing that can be carried out without requiring the services of outside providers.

The risk assessment and healthcare information technology industries are highly competitive. We have many competitors, some of which have much more extensive experience in these industries and some of which have greater resources. We compete in the risk assessment business by seeking to provide a superior applicant experience, faster services completion and a wider array of quality, integrated services than our competitors. We compete in the healthcare information technology industry by offering solutions that foster better patient care and improve performance for healthcare providers, including smaller and medium sized physician practices.

GENERAL

Sales and Marketing. Our Diagnostic Information Services business has a unified commercial organization focused on the sale of most of our services. It coordinates closely with our clinical franchises (discussed above under the heading Our Strengths) and marketing organization. The commercial organization is centrally led, and is organized regionally, in conjunction with our operations organization, to focus on local customer needs and to ensure aligned delivery for our customers. Our commercial organization employs world-class processes and tools and strong management discipline. We provide industry-leading training and development, focus on opportunities with IDNs and specialty physicians, and foster a customer-focused, performance-driven culture. We also maintain distinct sales and marketing organizations for our employer drugs-of-abuse testing services in Diagnostic Information Services and our offerings in Diagnostic Solutions.

Information Technology. We use information systems extensively in virtually all aspects of our business, including clinical testing, test ordering and reporting, billing, customer service, logistics and management of medical data. We endeavor to establish systems that create value and efficiencies for our Company and customers. The successful delivery of our services depends, in part, on the continued and uninterrupted performance of our information technology systems. We take precautionary measures to prevent problems that could affect our information technology systems.

Some of our historic growth has come through acquisitions and, as a result, we continue to use multiple information systems. We have made significant progress implementing common systems, and we continue to standardize laboratory information and billing systems across our operations. We expect that our standardization effort will take several more years to complete, and will result in significantly more centralized systems, improved operating efficiency, more positive customer experiences and enhanced control over our operational environment. Even after we complete our efforts to standardize our historic systems, future business acquisitions may create additional opportunities where we may conclude that system standardization would benefit our company.

Quality Assurance. As discussed further under the heading Quality, our goal is to provide every patient with services and products of superior quality, and to meet that goal we have adopted the Quest Diagnostics Quality Program System. Employing root cause analysis, process improvements and rigorous tracking and measuring, we continuously seek to enhance quality, reduce defects, further increase the efficacy and efficiency of our operations and processes, eliminate waste and help standardize operations across our Company.

In our laboratory operations, our quality assurance efforts focus on pre-analytic, analytic and post-analytic processes, including positive patient identification of specimens, appropriate specimen transport, analysis and report accuracy, proficiency testing, reference range relevance, process audits, statistical process control and personnel training for all of our laboratories and patient service centers. As part of our quality assurance program, we utilize internal and external proficiency testing, comprehensive quality control and rigorous process audits. We monitor test results to identify trends, biases or imprecision in our analytical processes. We also focus on the licensing, credentialing, training and competence of our professional and technical staff.

Table of Contents

In addition, we have accreditation or licenses for our clinical laboratory operations from various regulatory agencies or accrediting organizations, such as CMS, CAP and certain states. All of our laboratories participate in external quality surveillance programs, including proficiency testing programs administered by CAP and several state agencies. CAP is an independent, nongovernmental organization of board-certified pathologists approved by CMS to inspect clinical laboratories to determine compliance with the standards required by CLIA. CAP offers an accreditation program to which clinical laboratories may voluntarily subscribe. All of our major laboratories, including our laboratories outside the U.S., and a number of our rapid response laboratories, are accredited by CAP. Accreditation includes on-site inspections and participation in the CAP (or equivalent) proficiency testing program. Also, our cytotechnologists and pathologists participate in an internal peer-review evaluation and one or more external individual proficiency testing programs. In addition, some of our laboratories also have International Organization for Standardization certification for their quality management systems.

For additional information about our commitment to quality, see "Our Strengths - Quality " on page 7.

Intellectual Property Rights. We own significant intellectual property, including patents, patent applications, technology, trade secrets, know-how, copyrights and trademarks in the United States and other countries. From time to time, we also license patents, patent applications, technology, trade secrets, know-how, copyrights or trademarks owned by others; we also may license our intellectual property to others. In the aggregate, our intellectual property assets and licenses are of material importance to our business. We believe, however, that no single patent, technology, trademark, intellectual property asset or license is material to our business as a whole. Our approach is to manage our intellectual property assets, to safeguard them and to maximize their value to our enterprise. We actively defend our important intellectual property assets and pursue protection of our products, processes and other intellectual property where possible.

Enterprise Risk Management Program. We maintain an enterprise risk management program designed to promote a culture of risk awareness throughout the Company's key business, operations and support functions. Our program, which is integrated with the Company’s governance, performance management and internal control frameworks, entails a formal continuous process that identifies, assesses, mitigates and manages the risks from both internal and external conditions that could significantly impact the Company and influence its business strategy and performance. The program is based on the most recent framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, which focuses on the following risk types:

•

Operational risk - risks arising from systems, processes, people and external events that affect the Company’s operational objectives or fundamental reason for its existence, including: product life-cycle and execution; service quality and performance; information management and data protection and security, including cybersecurity; supply chain and business disruption; and other risks, including human capital and reputation.


•	Financial risk - risks arising from the Company’s ability to meet its financial obligations pursuant to its strategic and operational objectives, including exposure to broad market and more specific industry risk that could impact liquidity, interest rate, credit, pricing and reimbursement, and also to internal and external financial reporting.


•	Legal and compliance risk - risks arising from government and regulatory environment and action, legal proceedings and compliance with integrity policies and procedures.


•	Strategic risk - risks that will impede the Company’s plan to achieve its mission and vision and apply its core values, including changes in the broad market and Company's industry, business development and restructuring activities, competitive threats and practices, technology and product innovation, and public policy.

As part of our program, we routinely assess our enterprise level risks, overall Company-level risk tolerance and the effectiveness of risk management, and monitor the progress of and resources applied to risk mitigation; our Board of Directors actively oversees our program. Our primary risk factors are discussed in Risk Factors beginning on page 28.

Billing; Government Reimbursement. We generally bill for diagnostic information services on a fee-for-service basis under one of two types of fee schedules; fees may be negotiated or discounted. The types of fee schedules are:


•	“Client” fees charged to physicians, hospitals and institutions for which services are performed on a wholesale basis and which are billed on a monthly basis.


•	“Patient” fees charged to individual patients and certain third-party payers on a claim-by-claim basis.

Table of Contents

Billing for diagnostic information services is very complicated. Patients, insurance companies, Medicare, Medicaid, physicians, hospitals, IDNs, ACOs and employer groups all have different billing requirements. Some billing arrangements require us to bill multiple payers, and there are several other factors that complicate billing (e.g., disparity in coverage and information requirements among payers; incomplete or inaccurate billing information provided by ordering clinicians; and lack of access to patients before testing). We maintain compliance policies and procedures for our billing practices, and we audit our practices for compliance with applicable laws and regulations and internal policies and procedures.

With regard to the clinical testing services performed on behalf of Medicare beneficiaries, we generally must bill Medicare directly and must accept the Medicare carrier's fee schedule amount for covered services as payment in full. In addition, state Medicaid programs are prohibited from paying more (and in most instances, pay significantly less) than Medicare. Currently, Medicare does not require the beneficiary to pay a co-payment for diagnostic testing services reimbursed under the Clinical Laboratory Fee Schedule, but generally does require a patient deductible for anatomic pathology services.

Part B of the Medicare program contains fee schedule payment methodologies for clinical testing services performed for covered patients, including a national ceiling on the amount that carriers could pay under their local Medicare clinical testing fee schedules. Historically, the Medicare Clinical Laboratory Fee Schedule and the Medicare Physician Fee Schedule established under that program have been subject to change, including each year. Pursuant to PAMA, CMS promulgated revised reimbursement schedules for 2018 - 2020 for clinical laboratory testing services provided under Medicare. Reimbursement rates for many clinical laboratory tests were reduced in 2018 and 2019 and are scheduled to be reduced again by approximately 10% in 2020 (rates, and reductions, vary by test). PAMA calls for further revision of the Medicare Clinical Laboratory Fee Schedule for years after 2020, based on future surveys of market rates; reimbursement reduction from 2021-23 is capped by PAMA at 15% annually. In late 2019, the LAB Act became law. The LAB Act provides an opportunity for reforms to PAMA by delaying PAMA's next data collection and reporting period until January 1, 2021 and by ordering a study to determine ways to improve future collection of more representative market rate data under PAMA.

Employees. At December 31, 2019, we employed approximately 47,000 people. This total excludes employees of the joint ventures where we do not have a majority ownership interest. We have no collective bargaining agreements with unions covering employees in the United States, and we believe that our overall relations with our employees are good.

REGULATION



We are subject to extensive and frequently changing laws and regulations in the United States (at both the federal and state levels) and other jurisdictions in which we conduct business, and to government inspections and audits.

Table of Contents



Key Regulatory Schemes (Table 16)
CLIA and State Clinical Laboratory Licensing	CLIA regulates the operations of virtually all clinical laboratories, requiring that they be certified by the federal government and that they comply with various technical, operational, personnel and quality requirements intended to ensure that the services provided are accurate, reliable and timely. State laws may require additional personnel qualifications or licenses, quality control, record maintenance, proficiency testing or detailed review of our scientific method validations and technical procedures for certain tests. Violations of these laws and regulations may result in monetary fines, criminal and civil penalties and/or suspension or exclusion from participation in Medicare, Medicaid and other federal or state healthcare programs.
Medicare and Medicaid; Fraud and Abuse	Diagnostic testing services provided under Medicare and Medicaid programs are subject to complex, evolving, stringent and frequently ambiguous federal and state laws and regulations, including those relating to billing, coverage and reimbursement. Anti-kickback laws and regulations prohibit making payments or furnishing other benefits to influence the referral of tests billed to Medicare, Medicaid or certain other federal or state healthcare programs. In addition, federal and state anti-self-referral laws generally prohibit Medicare and Medicaid payments for clinical tests referred by physicians who have an ownership or investment interest in, or a compensation arrangement with, the testing laboratory, unless specific exceptions are met. Federal substance abuse legislation enacted in 2018 contains anti-kickback provisions that are, by their terms, applicable to laboratory testing paid for by all payers. We are attempting to clarify the application of that legislation. Some states have similar laws that are not limited in applicability to only Medicare and Medicaid referrals and could also affect tests that are paid for by health plans and other non-governmental payers. Violations of these laws and regulations may result in monetary fines, criminal and civil penalties and/or suspension or exclusion from participation in Medicare, Medicaid and other federal or state healthcare programs.
FDA	The FDA has regulatory responsibility over, among other areas, instruments, software, test kits, reagents and other devices used by clinical laboratories to perform diagnostic testing in the United States. The FDA also regulates drugs-of-abuse testing for employers and insurers, testing for blood bank purposes and testing of donors of human cells for purposes such as in vitro fertilization. A number of advanced tests we develop internally are offered as LDTs. The FDA has claimed regulatory authority over all LDTs, but has stated that it exercised enforcement discretion with regard to most LDTs performed by high complexity CLIA-certified laboratories. Pursuant to the 21st Century Cures Act, the FDA issued final guidance regarding its position on the regulation of clinical decision software, which may be used in connection with LDTs. The guidance attempts to address uncertainty regarding whether FDA approval of certain software is required. In January 2019 the FDA issued a draft guidance on a pre-certification pilot program to help software developers have a speedier and less restrictive path to clearance or approval of their software. Legislation introduced in Congress would enable the FDA to regulate LDTs, in vitro diagnostics, software and other items used in the diagnosis of disease. If the legislation becomes law, the FDA could regulate diagnostic tests and components and platforms used as part of these tests. If the legislation becomes law, it could have a significant impact on the clinical laboratory testing industry, including regulating LDTs in new ways, while creating avenues of opportunity and competition regarding clinical laboratory testing. New competitors may enter the industry, and competition may come in new forms.

Environmental, Health and Safety	We are subject to laws and regulations related to the protection of the environment, the health and safety of employees and the handling, transportation and disposal of medical specimens, infectious and hazardous waste and radioactive materials. For example, the U.S. Occupational Safety and Health Administration has established extensive requirements relating specifically to workplace safety for healthcare employers in the U.S. This includes requirements to develop and implement multi-faceted programs to protect workers from exposure to blood-borne pathogens, including preventing or minimizing any exposure through needle stick injuries. For purposes of transportation, some biological materials and laboratory supplies are classified as hazardous materials and are subject to regulation by one or more of the following agencies: the U.S. Department of Transportation, the U.S. Public Health Service, the U.S. Postal Service and the International Air Transport Association.
Physicians	Our pathologists are required to hold a valid license to practice medicine in the jurisdiction in which they practice. Several jurisdictions, including some in which our businesses are located, prohibit business corporations from engaging in the practice of medicine. In certain jurisdictions, business corporations are prohibited from employing licensed healthcare professionals to provide services on behalf of the corporation; these laws vary. In some jurisdictions, anatomic pathology services are delivered through physician-owned entities that employ the practicing pathologists. The manner in which licensed physicians can be organized to perform medical services may be governed by the laws of the jurisdictions in which medical services are provided and by the medical boards or other entities authorized by these jurisdictions to oversee the practice of medicine.
Privacy and Security of Health and Personal Information	We are subject to laws and regulations regarding protecting the security and privacy of certain healthcare and personal information, including: (a) the federal Health Insurance Portability and Accountability Act and the regulations thereunder, which establish (i) a complex regulatory framework including requirements for safeguarding protected health information and (ii) comprehensive federal standards regarding the uses and disclosures of protected health information; (b) state laws, including the California Consumer Privacy Act (effective January 1, 2020); and (c) the European Union's General Data Protection Regulation. A healthcare provider may be subject to penalties for non-compliance and may be required to notify individuals or state, federal or county governments if the provider discovers certain breaches of personal information or protected health information.
Drug Testing; Controlled Substances	All U.S. laboratories that perform drug testing for certain public sector employees and employees of certain federally regulated businesses are required to be certified as meeting the detailed performance and quality standards of the Substance Abuse and Mental Health Services Administration. To obtain access to controlled substances used to perform drugs-of-abuse testing in the United States, laboratories must be licensed by the Drug Enforcement Administration.

Compliance. We strive to conduct our business in compliance with all applicable laws and regulations. We license and maintain appropriate accreditations for all of our laboratories and, where applicable, patient service centers, as required by the appropriate federal and state agencies. We have a long-standing and well-established compliance program. The Quality, Safety and Compliance Committee of our Board of Directors oversees, and receives periodic management reports regarding, our compliance program. Our program includes detailed policies and procedures and training programs intended to ensure the implementation and observance of all applicable laws and regulations (including regarding billing and reimbursement, and privacy of protected health information and personally identifiable information) and Company policies. Further, we conduct in-depth reviews of procedures and facilities to assure regulatory compliance throughout our operations. We conduct annual training of our employees on these compliance policies and procedures.

As an integral part of our billing compliance program, we investigate reported or suspected failures to comply with federal and state healthcare reimbursement requirements. Any Medicare or Medicaid overpayments resulting from non-compliance are refunded by us. As a result of these efforts, we have periodically identified and reported overpayments, refunded the payers for overpayments and taken appropriate corrective action.

Item 1A. Risk Factors

You should carefully consider all of the information set forth in this Report, including the following risk factors, before deciding to invest in any of our securities. The risks below are not the only ones that we face. Additional risks not presently known to us, or that we presently deem immaterial, may also negatively impact us. Our 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. Our results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks we face described below and elsewhere. See “Cautionary Factors that May Affect Future Results” on page 37.

Table of Contents

The U.S. healthcare system is evolving and medical laboratory testing market fundamentals are changing, and our business could be adversely impacted if we fail to adapt.

The U.S. healthcare system is evolving, in part in response to the ACA. The ACA established the Center for Medicare and Medicaid Innovation to examine alternative payment methodologies and conduct demonstration programs. The ACA provided for extensive health insurance reforms, including the elimination of pre-existing condition exclusions and other limitations on coverage, fixed percentages on medical loss ratios, expansion in Medicaid and other programs, employer mandates, individual mandates, creation of state and regional health insurance exchanges, and tax subsidies for individuals to help cover the cost of individual insurance coverage. The ACA also permits the establishment of ACOs.

Certain aspects of the ACA have been repealed, delayed or modified. The scope and timing of any further legislation to repeal, amend, replace, or reform the rest of the ACA is uncertain, but if such legislation were to become law, it could have a significant impact on the U.S. healthcare system. In addition, uncertainty regarding the status of the ACA prior to any such repeal, amendment, replacement or reform could create uncertainty generally in the healthcare market.

Several federal courts have recently issued determinations that portions of the ACA are unconstitutional; those rulings are net yet final. Uncertainty about court rulings regarding the ACA could add to uncertainty in the healthcare market.

Significant change is taking place in the healthcare system, including as discussed above under the heading The Clinical Testing Industry, beginning on page 13. For example, value-based reimbursement is increasing (e.g., UnitedHealthcare's Preferred Lab Network); CMS has set goals for value-based reimbursement to be achieved. Patients are encouraged to take increased interest in and responsibility for, and often are bearing increased responsibility for payment for, their healthcare. Healthcare industry participants are evolving and consolidating. Healthcare services increasingly are being provided by non-traditional providers (e.g., physician assistants), in non-traditional venues (e.g., retail medical clinics, urgent care centers) and using new technologies (e.g., telemedicine, digital pathology). Utilization of the healthcare system is being influenced by several factors and may result in a decline in the demand for diagnostic information services.

In addition, we believe that clinical testing market fundamentals are changing. We believe that PAMA-driven reimbursement pressure is negatively impacting access to care and hurting the clinical testing industry, and remains a catalyst for structural change in the market. We also believe that our expanded health plan network access and increased health plan focus on driving better value in laboratory testing services will reduce variation in spending on these services. We also believe that ongoing consumerization in healthcare, with increased cost being borne by consumers, is sharpening focus on price disparities. We expect that the evolution of the healthcare industry will continue, and that industry change is likely to be extensive.

The clinical testing business is highly competitive, and if we fail to provide an appropriately priced level of service or otherwise fail to compete effectively it could have a material adverse effect on our revenues and profitability.

The clinical testing business remains a fragmented and highly competitive industry. We primarily compete with three types of clinical testing providers: other commercial clinical laboratories, hospital-affiliated laboratories and physician-office laboratories. We also compete with other providers, including anatomic pathology practices and large physician group practices. Hospitals generally maintain on-site laboratories to perform testing on their patients (inpatient or outpatient). In addition, many hospitals compete with commercial clinical laboratories for outreach (non-hospital patients) testing. Hospitals may seek to leverage their relationships with community clinicians and encourage the clinicians to send their outreach testing to the hospital's laboratory. As a result of this affiliation between hospitals and community clinicians, we compete against hospital-affiliated laboratories primarily based on quality and scope of service as well as pricing. In addition, hospitals that own physician practices may require the practices to refer testing to the hospital's laboratory. In recent years, there has been a trend of hospitals acquiring physician practices, increasing the percentage of physician practices owned by hospitals. Increased hospital ownership of physician practices may enhance clinician ties to hospital-affiliated laboratories and may strengthen their competitive position. The formation of ACOs and IDNs, and their approach to contracts with healthcare providers, in addition to the impact of informatics, also may increase competition to provide diagnostic information services.

The diagnostic information services industry also is faced with changing technology and new product introductions. Competitors may compete using advanced technology, including technology that enables more convenient or cost-effective testing. Digital pathology, still in an emerging state, is an example of this. Competitors also may compete on the basis of new service offerings. Competitors also may offer testing to be performed outside of a commercial clinical laboratory, such as (1) point-of-care testing that can be performed by physicians in their offices; (2) advanced testing that can be performed by hospitals in their own laboratories; and (3) home testing that can be carried out without requiring the services of outside providers.

Government payers, such as Medicare and Medicaid, have taken steps to reduce the utilization and reimbursement of healthcare services, including clinical testing services.

We face efforts by government payers to reduce utilization of and reimbursement for diagnostic information services. One example of this is increased use of prior authorization requirements. We expect efforts to reduce reimbursements, to impose more stringent cost controls and to reduce utilization of clinical test services will continue.

Pursuant to PAMA, CMS promulgated revised reimbursement rate schedules for 2018 - 2020 for clinical laboratory testing services provided under Medicare. Reimbursement rates for many clinical laboratory tests were reduced in 2018 and 2019 and are scheduled to be reduced again by approximately 10% in 2020 (rates, and reductions, vary by test). PAMA calls for further revision of the Medicare Clinical Laboratory Fee Schedule for years after 2020, based on future surveys of market rates; reimbursement rate reduction from 2021-23 is capped by PAMA at 15% annually. In late 2019, the LAB Act became law. The LAB Act provides an opportunity for reforms to PAMA by delaying PAMA's next data collection and reporting period until January 1, 2021 and by ordering a study to determine ways to improve future collection of more representative market rate data under PAMA.

In addition, CMS has adopted policies limiting or excluding coverage for clinical tests that we perform. We also provide physician services that are reimbursed by Medicare under a physician fee schedule, which is subject to adjustment on an annual basis. Medicaid reimbursement varies by state and is subject to administrative and billing requirements and budget pressures. The ACA includes further provisions that are designed to control utilization and payment levels.

In addition, over the last several years, the federal government has expanded its contracts with private health insurance plans for Medicare beneficiaries, called “Medicare Advantage” programs, and has encouraged such beneficiaries to switch from the traditional programs to the private programs. There has been growth of health insurance plans offering Medicare Advantage programs, and of beneficiary enrollment in these programs. States have mandated that Medicaid beneficiaries enroll in private managed care arrangements. In addition, state budget pressures have encouraged states to consider several courses of action that may impact our business, such as delaying payments, reducing reimbursement, restricting coverage eligibility, denying claims and service coverage restrictions.

From time to time, the federal government has considered whether competitive bidding could be used to provide clinical testing services for Medicare beneficiaries at attractive rates while maintaining quality and access to care. Congress periodically considers cost-saving initiatives. These initiatives have included coinsurance for clinical testing services, co-payments for clinical testing and further laboratory fee schedule reductions.

Health plans and other third parties have taken steps to reduce the utilization and reimbursement of health services, including clinical testing services.

We face efforts by non-governmental third-party payers, including health plans, to reduce utilization of and reimbursement for clinical testing services. Examples include increased use of prior authorization requirements and increased denial of coverage for services. Since the passage of ACA, there is increased market activity regarding alternative payment models, including bundled payment models. We expect continuing efforts by third-party payers, including in their rules, practices and policies, to reduce reimbursements, to impose more stringent cost controls and to reduce utilization of clinical testing services. ACOs and IDNs also may undertake efforts to reduce utilization of, or reimbursement for, diagnostic information services.

The healthcare industry has experienced a trend of consolidation among health insurance plans, resulting in fewer but larger insurance plans with significant bargaining power to negotiate fee arrangements with healthcare providers, including clinical testing providers. These health plans, and independent physician associations, may demand that clinical testing providers accept discounted fee structures or assume all or a portion of the financial risk associated with providing testing services to their members through capitated payment arrangements. Some health plans also are reviewing test coding, evaluating coverage decisions and requiring preauthorization of certain testing. There are also an increasing number of patients enrolling in consumer driven products and high deductible plans that involve greater patient cost-sharing.

The increased consolidation among health plans also has increased pricing transparency and bargaining power and the potential adverse impact of ceasing to be a contracted provider with any such insurer.

Government payers and third parties, including health plans, may not recognize the value of, or compensate or reimburse us for, new and innovative solutions.

Table of Contents

Government payers and third parties, including health plans, are taking steps to reduce utilization of, and reimbursement for, some new and innovative healthcare solutions, including new tests and other solutions that we may offer.

In response to requests from payers to have a strategy to report a single or at most a few codes to describe procedures used to perform molecular and toxicology testing, the American Medical Association CPT® Editorial Panel has established and replaced billing codes used to report those procedures. The adoption of these revised codes has resulted in limited coverage decisions on certain occasions, new requirements for documentation to facilitate payment from certain payers and increased payment denials. While some payers have adopted the new payment methods, others have not yet modified their systems and ask that laboratories continue to report their services using the previous reporting strategies, when those codes still exist.

These steps may discourage innovation and access to innovative solutions that we may offer.

Our business operations and reputation may be materially impaired if we do not comply with privacy laws or information security policies.

In our business, we collect, generate, process or maintain sensitive information, such as patient data and other personal information. If we do use or not adequately safeguard that information in compliance with applicable requirements under federal, state and international laws, or if it were disclosed to persons or entities that should not have access to it, our business could be materially impaired, our reputation could suffer and we could be subject to fines, penalties and litigation. In the event of a data security breach, we may be subject to notification obligations, litigation and governmental investigation or sanctions, and may suffer reputational damage, which could have an adverse impact on our business.

We are subject to laws and regulations regarding protecting the security and privacy of certain healthcare and personal information, including: (a) the federal Health Insurance Portability and Accountability Act and the regulations thereunder, which establish (i) a complex regulatory framework including requirements for safeguarding protected health information and (ii) comprehensive federal standards regarding the uses and disclosures of protected health information; (b) state laws, including the California Consumer Privacy Act; and (c) the European Union's General Data Protection Regulation.

Our business could be negatively affected if we are unable to continue to improve our efficiency.

It is important that we continue to improve our efficiency to enable us to mitigate the impact on our profitability of steps taken by government payers and health insurers to reduce the utilization and reimbursement of healthcare services, including diagnostic information services.

Business development activities are inherently risky and integrating our operations with businesses we acquire may be difficult.

We plan selectively to enhance our business from time to time through business development activities, such as acquisitions, licensing arrangements, investments and alliances. However, these plans are subject to the availability of appropriate opportunities and competition from other companies seeking similar opportunities. Moreover, the success of any such effort may be affected by a number of factors, including our ability to properly assess and value the potential business opportunity, and to integrate it into our business. The success of our strategic alliances depends not only on our contributions and capabilities, but also on the property, resources, efforts and skills contributed by our strategic partners. Further, disputes may arise with strategic partners, due to conflicting priorities or conflicts of interests.

Acquisitions are not all the same (e.g., asset acquisitions differ from acquisitions of equity interests); different acquisitions offer different risks. Acquisitions may involve the integration of a separate company that has different systems, processes, policies and cultures. Integration of acquisitions involves a number of risks including the diversion of management's attention to the assimilation of the operations of assets or businesses we have acquired, difficulties in the integration of operations and systems and the realization of potential operating synergies, the assimilation and retention of the personnel of the acquired businesses, challenges in retaining the customers of the combined businesses, and potential adverse effects on operating results. The process of combining acquisitions may be disruptive to our businesses and may cause an interruption of, or a loss of momentum in, such businesses as a result of the following difficulties, among others:


•	loss of key customers or employees;


•	difficulty in standardizing information and other systems;


•	difficulty in consolidating facilities and infrastructure;


•	failure to maintain the quality or timeliness of services that our Company has historically provided;

Table of Contents


•	diversion of management's attention from the day-to-day business of our Company as a result of the need to deal with the foregoing disruptions and difficulties; and


•	the added costs of dealing with such disruptions.

If we are unable successfully to integrate strategic acquisitions in a timely manner, our business and our growth strategies could be negatively affected. Even if we are able to successfully complete the integration of the operations of other assets or businesses we may acquire in the future, we may not be able to realize all or any of the benefits that we expect to result from such integration, either in monetary terms or in a timely manner.

We are subject to numerous legal and regulatory requirements governing our activities, and we may face substantial fines and penalties, and our business activities may be impacted, if we fail to comply.

Our business is subject to or impacted by extensive and frequently changing laws and regulations in the United States (including at both the federal and state levels) and the other jurisdictions in which we engage in business. While we seek to conduct our business in compliance with all applicable laws, many of the laws and regulations applicable to us are vague or indefinite and have not been interpreted by the courts, including many of those relating to:


•	billing and reimbursement of clinical testing;


•	certification or licensure of clinical laboratories;


•	the anti-self-referral and anti-kickback laws and regulations;


•	the laws and regulations administered by the FDA;


•	the corporate practice of medicine;


•	operational, personnel and quality requirements intended to ensure that clinical testing services are accurate, reliable and timely;


•	physician fee splitting;


•	relationships with physicians and hospitals;


•	safety and health of laboratory employees; and


•	handling, transportation and disposal of medical specimens, infectious and hazardous waste and radioactive materials.

These laws and regulations may be interpreted or applied by a prosecutorial, regulatory or judicial authority in a manner that could require us to make changes in our operations, including our pricing and/or billing practices. We may not be able to maintain, renew or secure required permits, licenses or any other regulatory approvals needed to operate our business or commercialize our services. If we fail to comply with applicable laws and regulations, or if we fail to maintain, renew or obtain necessary permits, licenses and approvals, we could suffer civil and criminal penalties, fines, exclusion from participation in governmental healthcare programs and the loss of various licenses, certificates and authorizations necessary to operate our business, as well as incur additional liabilities from third-party claims. If any of the foregoing were to occur, our reputation could be damaged and important business relationships with third parties could be adversely affected.

We regularly receive requests for information, and occasionally subpoenas, from governmental authorities. We also are subject from time to time to qui tam claims brought by former employees or other “whistleblowers.” The federal and state governments continue aggressive enforcement efforts against perceived healthcare fraud. Legislative provisions relating to healthcare fraud and abuse provide government enforcement personnel substantial funding, powers, penalties and remedies to pursue suspected cases of fraud and abuse. In addition, the government has substantial leverage in negotiating settlements since the amount of potential damages far exceeds the rates at which we are reimbursed for our services, and the government has the remedy of excluding a non-compliant provider from participation in the Medicare and Medicaid programs. Regardless of merit or eventual outcome, these types of investigations and related litigation can result in:


•	diversion of management time and attention;


•	expenditure of large amounts of cash on legal fees, costs and payment of damages;


•	increases to our administrative, billing or other operating costs;


•	limitations on our ability to continue some of our operations;


•	enforcement actions, fines and penalties or the assertion of private litigation claims and damages;


•	decreases to the amount of reimbursement related to diagnostic information services performed;


•	adverse affects to important business relationships with third parties;


•	decreased demand for our services; and/or


•	injury to our reputation.

Changes in applicable laws and regulations may result in existing practices becoming more restricted, or subject our existing or proposed services to additional costs, delay, modification, withdrawal or reconsideration. Such changes also could require us to modify our business objectives.

Our business could be adversely impacted by the FDA's approach to regulation.

The FDA has regulatory responsibility over, among other areas, instruments, software, test kits, reagents and other devices used by clinical laboratories to perform diagnostic testing in the U.S. A number of tests we develop internally are offered as LDTs. The FDA has claimed regulatory authority over all LDTs, but has stated that it exercised enforcement discretion with regard to most LDTs performed by high complexity CLIA-certified laboratories.

As the FDA moves to regulate more clinical laboratory testing, its approach to regulation is impacting industry practices and participants, new competitors may enter the industry, and competition may come in new forms.

Legislation introduced in Congress would enable the FDA to regulate LDTs, in vitro diagnostics, software and other items used in the diagnosis of disease. If the legislation becomes law, the FDA could regulate diagnostic tests and components and platforms used as part of these tests. If the legislation becomes law, it could have a significant impact on the clinical laboratory testing industry, including regulating LDTs in new ways, while creating avenues of opportunity and competition regarding clinical laboratory testing. New competitors may enter the industry, and competition may come in new forms.

Pursuant to the 21st Century Cures Act, the FDA issued final guidance regarding its position on the regulation of clinical decision software, which may be used in connection with LDTs. The guidance attempts to clarify whether FDA approval of certain software is required. In January 2019 the FDA issued a draft guidance on a pre-certification pilot program to help software developers have a speedier and less restrictive path to clearance or approval of their software.

Failure to accurately bill for our services, or to comply with applicable laws relating to government healthcare programs, could have a material adverse effect on our business.

Billing for diagnostic information services is complex and subject to extensive and non-uniform rules and administrative requirements. Depending on the billing arrangement and applicable law, we bill various payers, such as patients, insurance companies, Medicare, Medicaid, clinicians, hospitals and employer groups. The majority of billing and related operations for our Company are being provided by a third party under the Company's oversight. Failure to accurately bill for our services could have a material adverse effect on our business. In addition, failure to comply with applicable laws relating to billing government healthcare programs may result in various consequences, including: civil and criminal fines and penalties, exclusion from participation in governmental healthcare programs and the loss of various licenses, certificates and authorizations necessary to operate our business, as well as incur additional liabilities from third-party claims, all of which could have a material adverse effect on our business. Certain violations of these laws may also provide the basis for a civil remedy under the federal False Claims Act, including fines and damages of up to three times the amount claimed. The qui tam provisions of the federal False Claims Act and similar provision in certain state false claims acts allow private individuals to bring lawsuits against healthcare companies on behalf of government payers, private payers and/or patients alleging inappropriate billing practices.

Although we believe that we are in compliance, in all material respects, with applicable laws and regulations, there can be no assurance that a regulatory agency or tribunal would not reach a different conclusion. The federal or state government may bring claims based on our current practices, which we believe are lawful. The federal and state governments have substantial leverage in negotiating settlements since the amount of potential damages and fines far exceeds the rates at which we are reimbursed, and the government has the remedy of excluding a non-compliant provider from participation in the Medicare and Medicaid programs. We believe that federal and state governments continue aggressive enforcement efforts against perceived healthcare fraud. Legislative provisions relating to healthcare fraud and abuse provide government enforcement personnel with substantial funding, powers, penalties and remedies to pursue suspected cases of fraud and abuse.

Hardware and software failures or delays in our information technology systems, including failures resulting from our systems conversions or otherwise, could disrupt our operations and cause the loss of confidential information, customers and business opportunities or otherwise adversely impact our business.

IT systems are used extensively in virtually all aspects of our business, including clinical testing, test reporting, billing, customer service, logistics and management of medical data. Our success depends, in part, on the continued and uninterrupted performance of our IT systems. A failure or delay in our IT systems could impede our ability to serve our customers and patients and protect their confidential personal data. Despite redundancy and backup measures and precautions that we have implemented, our IT systems may be vulnerable to damage, disruptions and shutdown from a variety of sources, including telecommunications or network failures, system conversion or standardization initiatives, human acts and natural disasters. These issues can also arise as a result from failures by third parties with whom we do business and for which we have limited control. Any disruption or failure of our IT systems could have a material impact on our ability to serve our customers and patients, including negatively affecting our reputation in the marketplace.

The IT systems that we rely on may be subject to unauthorized tampering, cyberattack or other security breach.

Our IT systems are subject to potential cyberattacks, tampering or other security breaches. These attacks, if successful, could result in shutdowns or significant disruptions of our IT systems and/or in unauthorized persons misappropriating intellectual property and other confidential information, including patient data that we obtain, transmit and store on and through our IT systems.

External actors may develop and deploy viruses and other malicious software programs, including those that target our employees, designed to attack our IT systems or otherwise exploit security vulnerabilities, such as electronic spamming, phishing, spear phishing or similar tactics. As a result of the difficulty in detecting many of these attacks, intrusions and breaches, failures or losses may be repeated or compounded before they are discovered or rectified, which could further increase these costs and consequences. In December 2016, we reported that an internet application on our IT network had been the target of an external cyberattack, resulting in the theft of certain patient data. The accessed data did not include Social Security numbers, credit card information, or insurance and other financial information, and there is no indication that patient data has been misused in any way. When the intrusion was discovered, we immediately took steps to stop any further unauthorized activity.

From time to time, our IT systems have experienced other attacks, viruses, attempted intrusions or similar problems, but each was mitigated. None materially disrupted, interrupted, damaged or shutdown the company's IT systems, materially disrupted the Company's performance of its business or, to the Company's knowledge, resulted in material unauthorized access to data.

In addition, certain third parties to whom we outsource certain of our services or functions, or with whom we interface, store our confidential patient data or other confidential information, as well as those third parties’ providers, are also subject to the risks outlined above. A breach or attack affecting these third parties could also harm our business, results of operations and reputation and subject us to liability.

On June 3, 2019, the Company reported that Retrieval-Masters Creditors Bureau, Inc./American Medical Collection Agency (“AMCA”), informed the Company and Optum360 LLC, which provides revenue management services to the Company, about a data security incident involving AMCA (the “AMCA Data Security Incident”). AMCA (which provided debt collection services for Optum360) informed the Company and Optum360 that AMCA had learned that an unauthorized user had access to AMCA’s system between August 1, 2018 and March 30, 2019. AMCA first informed the Company of the AMCA Data Security Incident on May 14, 2019. AMCA’s affected system included financial information (e.g., credit card numbers and bank account information), medical information and other personal information (e.g., social security numbers). Test results were not included. Neither Optum360’s nor the Company’s systems or databases were involved in the incident. AMCA has also informed us that information pertaining to other laboratories’ customers was also affected.

Although the Company has robust security measures implemented, which are monitored and routinely tested both by internal resources and external parties, cyber threats against us or our third party providers continue to evolve and are often not recognized until such attacks are launched against a potential target. There can be no assurance that the Company or its third party providers can anticipate all such evolving future attacks, viruses or intrusions, implement adequate preventative measures, nor remediate any security vulnerabilities. Such breaches could expose our or our third party providers' IT systems to attack, which could result in major disruption of our business, and compromise our customer’s confidential information, result in litigation and potential liability for the Company, government investigation, significant damage to our reputation or otherwise adversely affect our business. Any mitigation or remediation efforts that we undertake may require expenditures of significant resources and the diversion of the attention of management.

We have taken, and continue to take, precautionary measures to reduce the risk of, and detect and respond to, future cyber threats, and prevent or minimize vulnerabilities in our IT systems, including the loss or theft of intellectual property, patient data or other confidential information that we obtain and store on our systems. We also have taken, and will continue to take, measures to assess the cybersecurity protections used by our third-party providers. In addition, we collaborate with government agencies regarding potential cyber threats and have worked with a leading cyber security firm to evaluate and strengthen our systems. There can be no assurances that our precautionary measures or measures used by our third-party providers will prevent, contain or successfully defend against cyber or information security threats that could have a significant impact on our business, results of operations and reputation and subject us to liability.

Failure to develop, or acquire licenses for, new tests, technology and services could negatively impact our testing volume and revenues.

The diagnostic information services industry is faced with changing technology and new product introductions. Other companies or individuals, including our competitors, may obtain patents or other property rights that would prevent, limit or interfere with our ability to develop, perform or sell our solutions or operate our business or increase our costs. In addition, they could introduce new tests, technologies or services that may result in a decrease in the demand for our services or cause us to reduce the prices of our services. Our success in continuing to introduce new solutions, technology and services will depend, in part, on our ability to license new and improved technologies on favorable terms. We may be unable to develop or introduce new solutions or services. Other companies or individuals, including our competitors, may obtain patents or other property rights on tests or processes that we may be performing, that could prevent, limit or interfere with our ability to develop, perform or sell our tests or operate our business. We also may be unable to continue to negotiate acceptable licensing arrangements, and arrangements that we do conclude may not yield commercially successful clinical tests. If we are unable to license these testing methods at competitive rates, our research and development costs may increase as a result. In addition, if we are unable to develop and introduce, or license, new solutions, technology and services to expand our advanced testing capabilities, our services may become outdated when compared with our competition.

We may be unable to obtain, maintain or enforce our intellectual property rights and may be subject to intellectual property litigation that could adversely impact our business.

We may be unable to obtain or maintain adequate patent or other proprietary rights for our solutions or services or to successfully enforce our proprietary rights. In addition, we may be subject to intellectual property litigation and we may be found to infringe on the proprietary rights of others, which could force us to do one or more of the following:


•	cease developing, performing or selling solutions or services that incorporate the challenged intellectual property;


•	obtain and pay for licenses from the holder of the infringed intellectual property right;


•	redesign or re-engineer our tests;


•	change our business processes; or


•	pay substantial damages, court costs and attorneys' fees, including potentially increased damages for any infringement held to be willful.

The development of new technologies (including artificial intelligence technologies) may impact the healthcare industry, and the development of new, more cost-effective solutions that can be performed by our customers or by patients, and the continued internalization of testing by hospitals or clinicians, could negatively impact our testing volume and revenues.

The diagnostic information services industry is faced with changing technology and new product introductions, including technology that enables more convenient or cost-effective testing. For example, digital pathology is an emerging technology that may change the practice of pathology. Information technology that includes self-learning or "artificial intelligence" features is growing and may impact the healthcare industry.

Table of Contents

Competitors also may offer testing to be performed outside of a commercial clinical laboratory, such as (1) point-of-care testing that can be performed by clinicians in their offices; (2) complex testing that can be performed by hospitals in their own laboratories; and (3) home testing that can be carried out without requiring the services of outside providers. Advances in technology also may lead to the need for less frequent testing. Further, diagnostic tests approved or cleared by the FDA for home use are automatically deemed to be “waived” tests under CLIA and may be performed by patients in their homes; test kit manufacturers could seek to increase sales to patients of such test kits.

Some traditional customers for anatomic pathology services, including specialty physicians that generate biopsies through surgical procedures, such as dermatologists, gastroenterologists, urologists and oncologists, are consolidating, have added in-office histology labs or have retained pathologists to read cases on site. Hospitals also are internalizing clinical laboratory testing, including some non-routine and advanced testing. Internalization of testing may reduce demand for services previously referred to outside service providers, such as the Company.

Our outstanding debt may impair our financial and operating flexibility.

As of December 31, 2019, we had approximately $4.8 billion of debt outstanding. We do not have any off-balance sheet financing arrangements in place or available. Our debt agreements contain various restrictive covenants. These restrictions could limit our ability to use operating cash flow in other areas of our business because we must use a portion of these funds to make principal and interest payments on our debt. We have obtained ratings on our public debt from Standard and Poor's, Moody's Investor Services and Fitch Ratings. There can be no assurance that any rating so assigned will remain for any given period of time or that a rating will not be lowered or withdrawn entirely by a rating agency if in that rating agency's judgment future circumstances relating to the basis of the rating, such as adverse changes in our Company or our industry, so warrant. If such ratings are lowered, our borrowing costs could increase. Changes in our credit ratings, however, do not require repayment or acceleration of any of our debt.

We or our subsidiaries may incur additional indebtedness in the future. Our ability to make principal and interest payments will depend on our ability to generate cash in the future. If we incur additional debt, a greater portion of our cash flows may be needed to satisfy our debt service obligations and if we do not generate sufficient cash to meet our debt service requirements, we may need to seek additional financing. In that case, it may be more difficult, or we may be unable, to obtain financing on terms that are acceptable to us. As a result, we would be more vulnerable to general adverse economic, industry and capital markets conditions as well as the other risks associated with indebtedness.

Our ability to attract and retain qualified employees is critical to the success of our business and the failure to do so may materially adversely affect our performance.

Our people are a critical resource. The supply of qualified personnel may be limited and competition for qualified employees is strong. We may lose, or fail to attract and retain, key management personnel, or qualified skilled technical or professional employees (e.g., pathologists).

Failure to establish, and perform to, appropriate quality standards to assure that the appropriate standard of quality is observed in the performance of our diagnostic information services could adversely affect the results of our operations and adversely impact our reputation.

The provision of diagnostic information services involves certain inherent risks. The services that we provide are intended to provide information for healthcare providers in providing patient care. Therefore, users of our services may have a greater sensitivity to errors than the users of services or products that are intended for other purposes.

Negligence in performing our services can lead to injury or other adverse events. We may be sued under physician liability or other liability law for acts or omissions by our pathologists, laboratory personnel and hospital employees who are under the supervision of our hospital-based pathologists. We are subject to the attendant risk of substantial damages awards and risk to our reputation.

We are subject to numerous political, legal, operational and other risks as a result of our international operations which could impact our business in many ways.

Our international operations increase our exposure to risks inherent in doing business in non-U.S. markets, which may vary by market and include: intellectual property legal protections and remedies; weak legal systems which may affect our ability to enforce contractual rights; trade regulations and procedures and actions affecting approval, production, pricing,

Table of Contents

reimbursement and marketing of services; and challenges based on differing languages and cultures. International operations also require us to devote significant management resources to implement our controls and systems in new markets, and to comply with the U.S. Foreign Corrupt Practices Act and similar anti-corruption laws in non-U.S. jurisdictions.

Our operations may be adversely impacted by the effects of natural disasters such as hurricanes and earthquakes, public health emergencies and health pandemics, hostilities or acts of terrorism or other criminal activities. Such events may result in a decline in the number of patients who seek clinical testing services or in our employees' ability to perform their job duties. In addition, such events may interrupt our ability to transport specimens, to receive materials from our suppliers or otherwise to provide our services.

Adverse results in material litigation could have an adverse financial impact and an adverse impact on our client base and reputation.

We are involved in various legal proceedings arising in the ordinary course of business including, among other things, disputes as to intellectual property, professional liability and employee-related matters, as well as inquiries from governmental agencies and Medicare or Medicaid carriers. Some proceedings against us involve claims that are substantial in amount and could divert management's attention from operations. These proceedings also may result in substantial monetary damages.

(a)

Net revenues for the years ended December 31, 2019, 2018, 2017 and 2016 reflect the impact of new revenue recognition rules that became effective January 1, 2018 and were adopted on a retrospective basis; net revenues for the year ended December 31, 2015 have not been restated. On January 1, 2019, we adopted a new lease accounting standard, which required us to recognize an asset and a liability for most operating leases on our balance sheet. As of December 31, 2019, operating lease right-of-use assets and operating lease liabilities totaled $518 million and $558 million, respectively. Prior periods have not been restated. See Note 2 to the audited consolidated financial statements for further details on the adoption of new accounting standards.

•	pre-tax amortization expense of $96 million;


•	pre-tax charges of $78 million, primarily associated with systems conversions and integration incurred in connection with further restructuring and integrating our business; and

a net pre-tax gain of $89 million, primarily due to a gain associated with the sale and leaseback of a property, a gain associated with the decrease in the fair value of the contingent consideration accruals associated with previous acquisitions, and a gain associated with an insurance claim for hurricane related losses, partially offset by costs incurred related to a data security incident and non-cash asset impairment charges.

In addition to the items included in operating income, income from continuing operations included:

•	$1 million of pre-tax restructuring and integration charges associated with our Q² Solutions joint venture;

•

a provisional estimated income tax benefit of $106 million associated with the TCJA, including a deferred income tax benefit of $115 million primarily due to the remeasurement of our net deferred tax liabilities and reserves at the new combined federal and state income tax rate, partially offset by $9 million of current income tax expense primarily due to the mandatory repatriation toll charge on undistributed foreign earnings and profits;

QUEST DIAGNOSTICS INCORPORATED AND SUBSIDIARIES

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Our Company

Diagnostic Information Services

Quest Diagnostics empowers people to take action to improve health outcomes. We use our extensive database of clinical lab results to derive diagnostic insights that reveal new avenues to identify and treat disease, inspire healthy behaviors and improve healthcare management. Our diagnostic information services business ("DIS") provides information and insights based on the industry-leading menu of routine, non-routine and advanced clinical testing and anatomic pathology testing, and other diagnostic information services. We provide services to a broad range of customers, including patients, clinicians, hospitals, independent delivery networks ("IDNs"), health plans, employers and accountable care organizations ("ACOs"). We offer the broadest access in the United States to diagnostic information services through our nationwide network of laboratories, patient service centers and phlebotomists in physician offices and our connectivity resources, including call centers and mobile paramedics, nurses and other health and wellness professionals. We are the world's leading provider of diagnostic information services. We provide interpretive consultation with one of the largest medical and scientific staffs in the industry. Our DIS business makes up greater than 95% of our consolidated net revenues. During 2019, we processed approximately 175 million test requisitions through our extensive laboratory network.

The clinical testing that we perform is an essential element in the delivery of healthcare services. Clinicians use clinical testing for predisposition, screening, monitoring, diagnosis, prognosis and treatment choices of diseases and other medical conditions. The United States clinical testing industry consists of two segments. One segment, which we believe makes up approximately 36% of the total industry, includes hospital inpatient and outpatient testing. The second segment, which we believe makes up approximately 64% of the total industry, includes testing of persons who are not hospital patients, including testing done in commercial clinical laboratories, physician-office laboratories and other locations, as well as hospital outreach (non-hospital patients) testing. We believe that hospital-affiliated laboratories account for approximately 36% of the second segment, commercial clinical laboratories approximately 54% and physician-office laboratories and other locations account for the balance.

The clinical testing industry is subject to seasonal fluctuations in operating results and cash flows. Typically, testing volume declines during vacation and major holiday periods, reducing net revenues and operating cash flows below annual averages. Testing volume is also subject to declines due to severe weather or other events, which can deter patients from having testing performed and which can vary in duration and severity from year to year. Additionally, orders for clinical testing generated from clinician offices, hospitals and employers can be affected by factors such as changes in the United States economy and regulatory environment, which affect the number of unemployed and uninsured, and design changes in healthcare plans, which affect utilization as well as patient responsibility for healthcare costs.

The Company assess its revenue performance for the DIS business in part based upon volume, measured by test requisitions, and revenue per requisition. Each requisition form accompanies a patient specimen, indicating the test(s) to be performed and the party to be billed for the test(s). Revenue per requisition is impacted by various factors, including, among other items, the impact of fee schedule changes (i.e. unit price), test mix, payer mix, and the number of tests per requisition.

Diagnostic Solutions

In our Diagnostic Solutions ("DS") businesses, which represents the balance of our consolidated net revenues, we offer a variety of solutions for life insurers and healthcare organizations and clinicians. We are the leading provider of risk assessment services for the life insurance industry. In addition, we offer healthcare organizations and clinicians robust information technology solutions.

2019 Highlights


•	Our total net revenues of $7.7 billion were up 2.6% from the prior year.


•	In DIS:


◦	Revenues of $7.4 billion increased by 2.8% compared to the prior year, driven by organic volume growth (growth excluding the impact of acquisitions) and the impact of recent acquisitions, partially offset by a decline in revenue per requisition.


◦	Volume, measured by the number of requisitions, increased by 4.3% compared to the prior year, with organic growth and acquisitions contributing approximately 3.1% and 1.2%, respectively.


◦	Revenue per requisition decreased by 1.3% compared to the prior year.


•	DS revenues of $321 million decreased by 1.8% compared to the prior year.


•	Income from continuing operations attributable to Quest Diagnostics' stockholders was $838 million, or $6.13 per diluted share, in 2019, compared to $736 million, or $5.29 per diluted share, in 2018.


•	Net cash provided by operating activities was approximately $1.2 billion in both 2019 and 2018.

Senior Notes Offering

In March 2019, we completed a senior notes offering, consisting of $500 million aggregate principal amount of 4.20% senior notes due June 2029 (the "2029 Senior Notes"), which were issued at an original issue discount of $1 million. The net proceeds from the 2029 Senior Notes were used to repay in full the outstanding indebtedness under our senior notes due April 2019, to repay outstanding indebtedness under our secured receivables credit facility and for general corporate purposes.

For further details regarding our debt, see Note 13 to the audited consolidated financial statements.

AMCA Data Security Incident

On June 3, 2019, the Company reported that Retrieval-Masters Creditors Bureau, Inc./American Medical Collection Agency (“AMCA”) had informed the Company and Optum360 LLC ("Optum360"), which provides revenue management services to the Company, about a data security incident involving AMCA (the “AMCA Data Security Incident”). AMCA (which provided debt collection services to Optum360) informed the Company and Optum360 that AMCA had learned that an unauthorized user had access to AMCA’s system between August 1, 2018 and March 30, 2019. AMCA first informed the Company of the AMCA Data Security Incident on May 14, 2019. AMCA’s affected system included financial information (e.g., credit card numbers and bank account information), medical information and other personal information (e.g., social security numbers). Test results were not included. Neither Optum360’s nor the Company’s systems or databases were involved in the incident. AMCA also informed us that information pertaining to other laboratories’ customers was also affected. Following announcement of the AMCA Data Security Incident, AMCA sought protection under the U.S. bankruptcy laws. While the impact of this incident to the Company's results of operations and cash flows was not material for the year ended December 31, 2019, our future financial results may be negatively impacted by costs associated with the incident and disruption of our accounts receivable collection processes.

Two Point Strategy

Our two point strategy is described in detail in "Item 1. Business: Our Strategy." We continued to execute our strategy during 2019 as follows:

Long-term Strategic Partnership with UnitedHealthcare

Effective January 1, 2019, we established a long-term strategic partnership with UnitedHealthcare, including collaborating on a variety of value-based programs. On July 1, 2019, we became a UnitedHealthcare Preferred Lab Network provider, meeting exceptional criteria for access, cost, data, quality and service.

Acquisition of the Clinical Laboratory Services Business of Boyce & Bynum Pathology Laboratories, P.C.

On February 11, 2019, we completed our acquisition of certain assets of the clinical laboratory services business of Boyce & Bynum Pathology Laboratories, P.C. ("Boyce & Bynum"), in an all cash transaction for $61 million, which consisted of cash consideration of $55 million and contingent consideration initially estimated at $6 million. The contingent consideration arrangement is dependent upon the achievement of certain testing volume benchmarks. The acquired business is included in our DIS business.

For details regarding our acquisitions, see Note 6 to the audited consolidated financial statements.

Invigorate Program

We are engaged in a multi-year program called Invigorate, which is designed to reduce our cost structure and improve our performance. We currently aim annually to save approximately 3% of our costs, and in 2019 we achieved that goal.

Invigorate has consisted of several flagship programs, with structured plans in each, to drive savings and improve performance across the customer value chain. These flagship programs include: organization excellence; information technology excellence; procurement excellence; field and customer service excellence; lab excellence; and revenue services excellence. In addition to these programs, we have identified key themes to change how we operate including reducing denials and patient concessions; further digitizing our business; standardization and automation; and optimization initiatives in our lab network and patient service center network. We believe that our efforts to standardize our information technology systems, equipment and data also foster our efforts to strengthen our foundation for growth and support the value creation initiatives of our clinical franchises by enhancing our operational flexibility, empowering and enhancing the customer experience, facilitating the delivery of actionable insights and bolstering our large data platform.

For the year ended December 31, 2019, we incurred $60 million of pre-tax charges under our Invigorate program primarily consisting of systems conversion and integration costs, all of which result in cash expenditures. Additional restructuring charges may be incurred in future periods as we identify additional opportunities to achieve further cost savings.

For further details of the Invigorate program and associated costs, see Note 5 to the audited consolidated financial statements.

Outlook and Trends

The healthcare system in the United States is evolving; significant change is taking place in the system. We expect that the evolution of the healthcare industry will continue, and that industry change is likely to be extensive. There are a number of key trends that are having, and that we expect will continue to have, a significant impact on the diagnostic information services business in the United States and on our business. We believe that several of the trends, including consolidation, price transparency and consumerization, are favorable to our business. For additional information on our key trends, which present both opportunities and risks, see "Item 1. Business: The Clinical Testing Industry."

Healthcare market participants, including governments, are focusing on controlling costs, including potentially by reducing reimbursement for healthcare services, changing reimbursement for healthcare services (including but not limited to a shift from fee-for-service to capitation), changing medical coverage policies (e.g., healthcare benefits design), denying coverage for services, requiring preauthorization of laboratory testing, requiring co-pays, introducing laboratory spend management utilities and payment and patient care innovations such as ACOs and patient-centered medical homes. The ongoing trend of rising patient responsibility and increasing payer denials has resulted in an increase in patient revenues as a percentage of total revenue, which has resulted in an increase in our reserves for patient price concessions. As health plans and government programs require greater levels of patient cost-sharing, our patient price concessions may continue to be negatively impacted and adversely impact our results of operations. As previously mentioned, there could be a shift to capitation arrangements where we agree to a predetermined monthly reimbursement rate for each member enrolled in a restricted plan, generally regardless of the number or cost of services provided by us. In both 2019 and 2018, we derived approximately 3% of our consolidated net revenues from capitated payment arrangements. In 2019 and 2018, we derived approximately 10% and 11%, respectively, of our testing volume from capitated payment arrangements.

Historically, the Medicare Clinical Laboratory Fee Schedule ("CLFS") and the Medicare Physician Fee Schedule established under Part B of the Medicare program have been subject to change, including each year. Pursuant to the Protecting Access to Medicare Act ("PAMA"), the Centers for Medicare and Medicaid Services ("CMS") promulgated revised reimbursement schedules for 2018-2020 for clinical laboratory testing services provided under Medicare. Under the revised

Table of Contents

Medicare Clinical Laboratory Fee Schedule (in 2019 CLFS revenues comprised 11% of our consolidated net revenues), reimbursement rates for clinical laboratory testing were reduced in 2018 and 2019 and are scheduled to be reduced again by approximately 10% in 2020. PAMA calls for further revision of the CLFS for years after 2020, based on future surveys of market rates; reimbursement reduction from 2021-23 is capped by PAMA at 15%. In late 2019, the Laboratory Access for Beneficiaries Act (the “LAB Act”) was signed into law. The LAB Act delays PAMA's next data collection and reporting period until January 1, 2021 and orders a study to determine ways to improve future collection of more representative market rate data under PAMA. We expect total reimbursement rate pressure for 2020 to be slightly more than 2%, of which PAMA and associated impacts are expected to be $80 million to $85 million. We expect a similar impact from PAMA in 2021.

In addition, the trend of consolidating, converging and diversifying among our customers and payers has continued. Consolidation is increasing price transparency and bargaining power, and encouraging internalization of clinical testing. We also believe that PAMA may be a further catalyst for consolidation as diagnostic information services providers realize lower Medicare reimbursement rates and large diagnostic information services providers may be able to increase their share of the overall diagnostic information services industry due to their large networks and lower cost structures.

For additional information on our key trends, which present both opportunities and risks, see "Item 1. Business: The Clinical Testing Industry."

Impact of New Accounting Standards

The adoption of new accounting standards, including the new standard related to accounting for leases, are discussed in Note 2 to the audited consolidated financial statements. For further details regarding our leases, refer to Note 14 to the audited consolidated financial statements.

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and assumptions and select accounting policies that affect our reported financial results and the disclosure of contingent assets and liabilities.

Our revenues are primarily comprised of a high volume of relatively low-dollar transactions, and about one-half of our total costs and expenses consist of employee compensation and benefits. Due to the nature of our business, several of our accounting policies involve significant estimates and judgments:


•	revenues and accounts receivable associated with DIS;


•	reserves for general and professional liability claims;


•	reserves for other legal proceedings; and


•	accounting for and recoverability of goodwill.

Revenues and accounts receivable associated with DIS

The process for estimating revenues and the ultimate collection of receivables associated with our DIS business involves significant assumptions and judgments. We recognize as revenue the amount of consideration to which we expect to be entitled upon completion of the testing process, when results are reported, or when services have been rendered. We estimate the amount of consideration we expect to be entitled to receive from customer groups, using the portfolio approach, in exchange for providing services. These estimates include the impact of contractual allowances, including payer denials, and price concessions, as discussed below. The portfolios determined using the portfolio approach consist of the following customers:


•	Healthcare Insurers


•	Government Payers


•	Client Payers


•	Patients

Table of Contents

We have a standardized approach to estimate the amount of consideration that we expect to be entitled to, including the impact of contractual allowances, including payer denials, and price concessions. Historical collection and payer reimbursement experience (along with the period the receivables have been outstanding) is an integral part of the estimation process related to revenues and receivables. Adjustments to our estimated contractual allowances and implicit price concessions are recorded in the current period as changes in estimates. Further adjustments to the allowances, based on actual receipts, may be recorded upon settlement.

We regularly assess the state of our billing operations in order to identify issues which may impact the collectibility of receivables or revenue estimates. We believe that the collectibility of our receivables is directly linked to the quality of our billing processes, most notably those related to obtaining the correct information in order to bill effectively for the services we provide. As such, we continue to implement “best practices” and endeavor to increase the use of electronic ordering to reduce the number of requisitions that we receive from healthcare providers with missing or incorrect billing information. We believe that our collection and revenue estimation processes, along with our close monitoring of our billing operations, help to reduce the risk associated with material adjustments to reserve estimates. However, changes to our estimate of the impact of contractual allowances, including payer denials, and price concessions could have a material impact on our results of operations and financial condition in the period that the estimates are adjusted.

The following table shows the approximate percentage of our total requisition volume and net revenues associated with our DIS business during 2019 applicable to each customer group:



	% of	% of
	Total	Consolidated
	Volume	Net Revenues

Healthcare Insurers	46%	36%
Government Payers	12	15
Client Payers	37	32
Patients *	1	13
Total DIS	96%	96%

*Patient revenue includes co-pays and deductibles but volume associated with such revenue is reported under Healthcare Insurers.

The following table shows net accounts receivable as of December 31, 2019 applicable to each payer group:



	% of
	Consolidated

Client Payers	42
Patients (including coinsurance and deductible responsibilities)	20
Total DIS	95%

Healthcare insurers

Reimbursements from healthcare insurers are based on fee-for-service schedules and on capitated payment rates. Under fee-for-service arrangements, healthcare insurers are billed at our Company's list price. Net revenues recognized consist of amounts billed net of contractual allowances for differences between amounts billed and the estimated consideration we expect to receive from such payers, which considers historical denial and collection experience and the terms of our contractual arrangements.

Substantially all of the accounts receivable due from healthcare insurers represent amounts billed under fee-for-service arrangements. Collection of our Company's net revenues from healthcare insurers is normally a function of providing complete and correct billing information to the healthcare insurers within the various filing deadlines and generally occurs within 30 to 60 days of billing. Provided we have billed healthcare insurers accurately with complete information prior to the established

Table of Contents

filing deadline, there has historically been little to no credit risk. If there has been a delay in billing, we determine if the amounts in question will likely go past the filing deadline, and if so, we will reserve accordingly for the billing.

Under capitated arrangements with healthcare insurers, we recognize revenue based on a predetermined monthly reimbursement rate for each member of an insurer's health plan regardless of the number or cost of services provided by us. Under capitated payment arrangements, the healthcare insurers typically reimburse us in the same month services are performed, essentially giving rise to no outstanding accounts receivable at the end of a reporting period. If any capitated payments are not received on a timely basis, we determine the cause and make a separate determination as to whether or not the collection of the amount from the healthcare insurer is at risk and, if so, would reserve accordingly.

Government payers

Reimbursements from government payers are based on fee-for-service schedules set by governmental authorities, including traditional Medicare and Medicaid. Net revenues recognized consist of amounts billed net of contractual allowances for differences between amounts billed and the estimated consideration we expect to receive from such payers, which considers historical denial and collection experience.

Collection of our Company's net revenues from government payers is normally a function of providing the complete and correct billing information within the various filing deadlines. Collection generally occurs within 30 days of billing. Provided we have billed government payers accurately with complete information prior to the established filing deadline, there has historically been little to no credit risk. If there has been a delay in billing, we determine if the amounts in question will likely go past the filing deadline, and, if so, we will reserve for the billing accordingly.

Client payers

Client payers include physicians, hospitals, ACOs, IDNs, employers, other commercial laboratories and institutions for which services are performed on a wholesale basis, and are billed based on a negotiated fee schedule. Credit risk and ability to pay are more of a consideration for these payers than healthcare insurers and government payers. Collection of consideration we expect to receive generally occurs within 60 to 90 days of billing. In addition to our standard approach to establishing allowances for doubtful accounts (which considers a number of factors including the period the receivables have been outstanding), our approach to client payer receivables also focuses on specific account reviews, historical collection experience and other factors.

Patients

Uninsured patients are billed based on established patient fee schedules or fees negotiated with physicians on behalf of their patients. Insured patients (includes coinsurance and deductible responsibilities) are billed based on fees negotiated with healthcare insurers. Collection of billings from patients is subject to credit risk and ability of the patients to pay. Net revenues consist of amounts billed net of discounts provided to uninsured patients in accordance with our policies and implicit price concessions. Implicit price concessions represent differences between amounts billed and the estimated consideration we expect to receive from patients, which considers historical collection experience (along with the period the receivables have been outstanding) and other factors including current market conditions. Patient billings are generally fully reserved for when the related billing reaches 210 days outstanding. Balances are automatically written off when they are sent to collection agencies. Allowances are further adjusted for estimated recoveries of amounts sent to collection agencies based on historical collection experience, which is regularly monitored. Collection of consideration we expect to receive generally occurs within 30 to 60 days of billing.

Reserves for general and professional liability claims

As a general matter, providers of diagnostic information services may be subject to lawsuits alleging negligence or other similar claims. These suits could involve claims for substantial damages. Any professional liability litigation could also have an adverse impact on our client base and reputation. We maintain various liability insurance coverages for claims that could result from providing, or failing to provide, clinical testing services, including inaccurate testing results, and other exposures. Our insurance coverage limits our maximum exposure on individual claims; however, we are essentially self-insured for a significant portion of these claims. While the basis for claims reserves is actuarially determined losses based upon our historical and projected loss experience, the process of analyzing, assessing and establishing reserve estimates relative to these types of claims involves a high degree of judgment. Although we believe that our present reserves and insurance coverage are sufficient to cover currently estimated exposures, it is possible that we may incur liabilities in excess of our recorded reserves or insurance coverage. Changes in the facts and circumstances associated with claims could have a material

Table of Contents

impact on our results of operations (principally costs of services), cash flows and financial condition in the period that reserve estimates are adjusted or paid. See Note 18 to the audited consolidated financial statements for a discussion of our reserves for general and professional liability claims.

Reserves for other legal proceedings

Our businesses are subject to or impacted by extensive and frequently changing laws and regulations, including inspections and audits by governmental agencies, in the United States (at both the federal and state levels) and the other jurisdictions in which we conduct business. Although we believe that we are in compliance, in all material respects, with applicable laws and regulations, there can be no assurance that a regulatory agency would not reach a different conclusion. Any noncompliance by us with applicable laws and regulations could have a material adverse effect on our results of operations. In addition, these laws and regulations may be interpreted or applied by a prosecutorial, regulatory or judicial authority in a manner that could require us to make changes in our operations, including our pricing and/or billing practices. We have, in the past, entered into several settlement agreements with various government and private payers relating to industry-wide billing and marketing practices that had been substantially discontinued. The federal or state governments may bring claims based on our current practices, which we believe are lawful. In addition, certain federal and state statutes, including the qui tam provisions of federal and state false claims acts, allow private individuals to bring lawsuits against healthcare companies on behalf of government or private payers alleging inappropriate billing practices. We are aware of certain pending lawsuits including class action lawsuits, and have received subpoenas related to billing practices. See Note 18 to the audited consolidated financial statements for a discussion of the various legal proceedings that involve our Company.

The process of analyzing, assessing and establishing reserve estimates relative to legal proceedings involves a high degree of judgment. Management has established reserves for legal proceedings in accordance with generally accepted accounting principles. Changes in facts and circumstances related to such proceedings could lead to significant adjustments to reserve estimates for such matters and could have a material impact on our results of operations, cash flows and financial condition in the period that reserve estimates are adjusted or paid.

Accounting for and recoverability of goodwill

We do not amortize goodwill, but evaluate the recoverability and measure the potential impairment of our goodwill annually, or more frequently, in the case of other events that indicate a potential impairment. We have identified the following reporting units for goodwill impairment testing in 2019:


•	DIS business;


•	Risk assessment services business which is part of our DS businesses

The DIS reporting unit components have been aggregated into a single reporting unit because they have similar economic characteristics, including similarities in financial performance, nature of products or services, nature of production processes and types of customers.

Goodwill is evaluated for impairment annually, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The annual impairment test includes an option to perform a qualitative assessment of whether it is more likely than not that a reporting unit's fair value is less than its carrying value; the qualitative analysis may be performed prior to, or as an alternative to, performing a quantitative goodwill impairment test. In evaluating whether it is more likely than not that the fair value of a reporting unit is less than its carrying value, we assess relevant events and circumstances, such as: (a) macroeconomic conditions; (b) industry and market considerations; (c) cost factors; (d) overall financial performance; (e) other relevant entity-specific events; (f) events affecting a reporting unit; and (g) a sustained decrease in share price. If, after assessing the totality of events or circumstances, we determine that it is more likely than not that the fair value of a reporting unit is less than its carrying value, then we are required to perform the quantitative goodwill impairment test. Otherwise, no further analysis is required. Additionally, our policy is to update the fair value calculation of our reporting units and perform the quantitative goodwill impairment test on a periodic basis.

The quantitative impairment test involves the comparison of the fair value of the reporting unit to its carrying value. If the carrying value is greater than our estimate of fair value, an impairment loss will be recognized in the amount of the excess. We calculate the fair value of each reporting unit using either a discounted cash flows analysis that converts future cash flow amounts into a single discounted present value amount or a market approach. We assess the valuation methodology based upon the relevance and availability of the data at the time we perform the valuation. The discounted cash flows analysis includes several unobservable inputs related to our own assumptions. The assumptions and estimates used in the discounted cash flows model are based upon the best available information in the circumstances and include a forecast of expected future cash flows,

Table of Contents

long-term growth rates, discount rates that are commensurate with economic risks, assumed income tax rates and estimates of capital expenditures and working capital. The fair values of the reporting units could be different if, for example, forecasted revenue growth rates, economic conditions, government regulations or actions by payers to control utilization of or reimbursement for healthcare services, turn out to be different than our assumptions or estimates. Changes in the assumed discount rates due to changes in interest rates could also affect the estimated fair values of the reporting units. We use a discount rate that considers a weighted average cost of capital plus an appropriate risk premium based upon the reporting unit being valued. Our analysis also considers publicly available information regarding the market capitalization of our Company, as well as (i) the financial projections and future prospects of our business, including its growth opportunities and likely operational improvements, and (ii) comparable sales prices, if available. We believe our estimation methods are reasonable and reflect common valuation practices.

On a quarterly basis, we perform a review of our business to determine if events or changes in circumstances have occurred which could have a material adverse effect on the fair value of our Company and its goodwill. If such events or changes in circumstances were deemed to have occurred, we would perform an impairment test of goodwill and record any noted impairment loss.

We perform our annual impairment test during the fourth quarter of the fiscal year. For the year ended December 31, 2019, we performed the qualitative assessment for our DIS and risk assessment services reporting units. Based on the totality of the information available for each reporting unit, we concluded that it was more likely than not that the estimated fair values were greater than the carrying values of the reporting units, and as such, no further analysis was required.

Operating Results

Results for the year ended December 31, 2019 were affected by certain items that on a net basis reduced diluted earnings per share from continuing operations by $0.43 as follows:


•	pre-tax amortization expense of $111 million ($96 million in amortization of intangible assets and $15 million in equity in earnings of equity method investees, net of taxes) or $0.61 per diluted share;


•	pre-tax charges of $78 million ($35 million in cost of services and $43 million in selling, general and administrative expenses), or $0.42 per diluted share, primarily associated with systems conversions and integration incurred in connection with further restructuring and integrating our business;

•

a net pre-tax gain of $89 million (a $95 million gain in other operating income, net offset by a $6 million charge in selling, general and administrative expenses), or $0.50 per diluted share, primarily due to a gain associated with the sale and leaseback of a property, a gain associated with the decrease in the fair value of the contingent consideration accruals associated with previous acquisitions, and a gain associated with an insurance claim for hurricane related losses, partially offset by costs incurred related to the AMCA Data Security Incident, and non-cash asset impairment charges; and


•	excess tax benefits associated with stock-based compensation arrangements of $13 million, or $0.10 per diluted share, recorded in income tax expense.

Results for the year ended December 31, 2018 were affected by certain items that on a net basis reduced diluted earnings per share from continuing operations by $1.02 as follows:


•	pre-tax amortization expense of $107 million ($90 million in amortization of intangible assets and $17 million in equity in earnings of equity method investees, net of taxes) or $0.57 per diluted share;


•	pre-tax charges of $122 million ($56 million in cost of services, $65 million in selling, general and administrative expenses, and $1 million in other operating income, net), or $0.66 per diluted share, primarily associated with workforce reductions, systems conversions and integration incurred in connection with further restructuring and integrating our business;


•	excess tax benefits associated with stock-based compensation arrangements of $18 million, or $0.13 per diluted share, recorded in income tax expense;

•

an income tax benefit of $14 million, or $0.09 per diluted share, associated with a change in a tax return accounting method that enabled us to accelerate the deduction of certain expenses on our 2017 tax return at the federal corporate statutory income tax rate in effect during 2017, partially offset by an income tax expense associated with finalizing the impact of the enactment of the Tax Cuts and Jobs Act ("TCJA"); and

•

net pre-tax charges of $2 million ($12 million in cost of services partially offset by a $10 million gain in other operating income, net), or $0.01 per diluted share, primarily attributable to costs incurred related to certain legal matters and a loss on the sale of a foreign subsidiary, which were partially offset by a gain associated with the decrease in the fair value of the contingent consideration accrual associated with a previous acquisition and an insurance claim for hurricane related losses.

Net Revenues

Net revenues for the year ended December 31, 2019 increased by 2.6% compared to the prior year.

DIS revenues for the year ended December 31, 2019 increased by 2.8% compared to the prior year driven by organic volume growth and the impact of recent acquisitions, partially offset by a decline in revenue per requisition.


•	Organic growth and acquisitions contributed approximately 1.1% and 1.7%, respectively, to DIS revenue growth.


•	DIS volume increased by 4.3%, with organic growth and acquisitions contributing approximately 3.1% and 1.2%, respectively, to DIS volume growth. Organic volume growth benefited from expanded in-network access primarily as a result of becoming a participating provider to UnitedHealthcare and Horizon Blue Cross Blue Shield of New Jersey.


•	Revenue per requisition decreased by 1.3% compared to the prior year primarily due to reimbursement pressure, including unit price reductions associated with PAMA and all other sources, of approximately 2.5%, and an increase in denials; partially offset by favorable mix, driven in part by acquisitions.

Table of Contents

Cost of Services

Cost of services consists principally of costs for obtaining, transporting and testing specimens as well as facility costs used for the delivery of our services.

Cost of services increased by $111 million for the year ended December 31, 2019 compared to the prior year. The increase was primarily driven by additional operating costs associated with our acquisitions; incremental operating expenses associated with organic volume growth; and higher depreciation expense associated with increased capital expenditures. These increases were partially offset by lower restructuring charges; incremental expense incurred in the prior year associated with reinvestments in the business with savings from tax reform; and cost reduction initiatives primarily under our Invigorate program. These initiatives enabled productivity gains as we leveraged our fixed cost structure to support the increase in volume.

Selling, General and Administrative Expenses ("SG&A")

SG&A consists principally of the costs associated with our sales and marketing efforts, billing operations, bad debt expense and general management and administrative support as well as administrative facility costs.

SG&A increased by $33 million for the year ended December 31, 2019, compared to the prior year, primarily driven by additional operating costs associated with our acquisitions; incremental operating expenses associated with organic volume growth; and higher costs associated with an increase in the value of our deferred compensation obligations. These increases were partially offset by incremental expense incurred in the prior year associated with reinvestments in the business with savings from tax reform; and cost reduction initiatives under our Invigorate program. These initiatives enabled productivity gains as we leveraged our fixed cost structure to support the increase in volume.

The increase in the value of our deferred compensation obligations is largely offset by gains due to the increase in the value of the associated investments, which are recorded in other income (expense), net. For further details regarding the Company's deferred compensation plans, see Note 17 to the audited consolidated financial statements.

Amortization of Intangible Assets

The $6 million increase in amortization of intangible assets for the year ended December 31, 2019 compared to the prior year was associated with our acquisitions.

Other Operating Income, net

Other operating income, net includes miscellaneous income and expense items and other charges related to operating activities.

For the year ended December 31, 2019, other operating income, net includes a $73 million gain associated with the sale and leaseback of a property, a $12 million gain associated with an insurance claim for hurricane related losses and a $12 million gain associated with the decrease in the fair value of the contingent consideration accruals associated with previous acquisitions, partially offset by non-cash asset impairment charges of $2 million.

For the year ended December 31, 2018, other operating income, net included a gain of $12 million associated with a decrease in the fair value of the contingent consideration accrual associated with a previous acquisition.

Interest Expense, net

Interest expense, net increased by $8 million for the year ended December 31, 2019 compared to the prior year, primarily driven by higher interest rates associated with our indebtedness, combined with higher average outstanding indebtedness due to refinancing activity during the year.

Other Income (Expense), net

Other income (expense), net represents miscellaneous income and expense items related to non-operating activities, such as gains and losses associated with investments and other non-operating assets.

Table of Contents

For the year ended December 31, 2019, other income (expense), net included $19 million of gains associated with investments in our deferred compensation plans.

For the year ended December 31, 2018, other income (expense), net included $6 million of losses associated with investments in our deferred compensation plans and the loss on the write-off of an equity investment.

Income Tax Expense

Income tax expense for the years ended December 31, 2019 and 2018 was $247 million and $182 million, respectively. The increase in income tax expense compared to the prior year was primarily driven by:


•	an increase in income from continuing operations before income taxes and equity in earnings of equity method investees;


•	a $15 million income tax benefit recognized in the prior year associated with a change in tax return accounting method that enabled us to accelerate the deduction of certain expenses on our 2017 tax return at the federal corporate statutory income tax rate in effect during 2017; and


•	$18 million of net income tax expense in 2019 associated with changes in reserves for uncertain tax positions compared to a $7 million net income tax benefit associated with changes in reserves for uncertain tax positions in the prior year primarily related to the expiration of the statute of limitations for certain income tax returns; partially offset by


•	a $12 million income tax benefit recognized in 2019 due to the release of valuation allowances associated with net operating loss carryforwards.

Equity in Earnings of Equity Method Investees, Net of Taxes

For the year ended December 31, 2019, there was a $13 million increase in equity in earnings of equity method investees, net of taxes, compared to the prior year, primarily associated with our investment in the Q² Solutions joint venture.

Discontinued Operations

During the third quarter of 2006, we completed the wind down of Nichols Institute Diagnostics ("NID"), a test kit manufacturing subsidiary, which has been classified as discontinued operations for all periods presented. Discontinued operations, net of taxes, for the year ended December 31, 2019 includes discrete tax benefits of $20 million associated with the favorable resolution of certain tax contingencies related to NID.

Quantitative and Qualitative Disclosures About Market Risk

We address our exposure to market risks, principally the risk of changes in interest rates, through a controlled program of risk management that includes the use of derivative financial instruments. We do not hold or issue derivative financial instruments for speculative purposes. We seek to mitigate the variability in cash outflows that result from changes in interest rates by maintaining a balanced mix of fixed-rate and variable-rate debt obligations. In order to achieve this objective, we have entered into interest rate swaps. Interest rate swaps involve the periodic exchange of payments without the exchange of underlying principal or notional amounts. Net settlements are recognized as an adjustment to interest expense. We believe that our exposures to foreign exchange impacts and changes in commodity prices are not material to our consolidated financial condition or results of operations. For further details regarding our significant accounting policies on interest rate risk and foreign currency, see Note 2 to the audited consolidated financial statements.

As of December 31, 2019 and 2018, the fair value of our debt was estimated at approximately $5.1 billion and $4.0 billion, respectively, using quoted prices in active markets and yields for the same or similar types of borrowings, taking into account the underlying terms of the debt instruments. As of December 31, 2019 and 2018, the estimated fair value exceeded the carrying value of the debt by $313 million and $85 million, respectively. A hypothetical 10% increase in interest rates (representing 28 basis points as of December 31, 2019 and 39 basis points as of December 31, 2018) would potentially reduce the estimated fair value of our debt by approximately $100 million and $88 million as of December 31, 2019 and 2018, respectively.

Borrowings under our secured receivables credit facility and our senior unsecured revolving credit facility are subject to variable interest rates. Interest on our secured receivables credit facility is based on either a rate that is intended to approximate commercial paper rates for highly rated issuers, or LIBOR, plus a spread. Interest on our senior unsecured revolving credit facility is subject to a pricing schedule that can fluctuate based on changes in our credit ratings. As such, our

Table of Contents

borrowing cost under this credit arrangement will be subject to both fluctuations in interest rates and changes in our credit ratings. As of December 31, 2019, the borrowing rates under these debt instruments were: for our secured receivables credit facility, commercial paper rates for highly rated issuers, or LIBOR, plus a spread of 0.70% to 0.725%; and for our senior unsecured revolving credit facility, LIBOR plus 1.125%. As of December 31, 2019, there were no borrowings outstanding under either our $600 million secured receivables credit facility or our $750 million senior unsecured revolving credit facility.

The notional amount of fixed-to-variable interest rate swaps outstanding as of both December 31, 2019 and 2018 was $1.2 billion. The aggregate fair value of the fixed-to-variable interest rate swaps was $28 million and $93 million, in a liability position, as of December 31, 2019 and 2018, respectively.

Based on our net exposure to interest rate changes, a hypothetical 10% change to the variable rate component of our variable rate indebtedness (representing 17 basis points) would potentially change annual interest expense by $2 million. A hypothetical 10% change in the forward one-month LIBOR curve (representing a 16 basis points change in the weighted average yield) would potentially change the fair value of our fixed-to-variable interest rate swap liabilities by $11 million.

In February 2019, we entered into interest rate lock agreements with several financial institutions for a total notional amount of $250 million to hedge a portion of our interest rate exposure associated with variability in future cash flows attributable to changes in the ten-year treasury rates related to the anticipated issuance of debt during 2019. In connection with the issuance of the 2029 Senior Notes, the agreements were settled and we paid $1 million. These losses are deferred in stockholders' equity, net of taxes, as a component of accumulated other comprehensive loss, and amortized as an adjustment to interest expense, net over the term of the 2029 Senior Notes.

During the third and fourth quarters of 2019, we entered into forward-starting interest rate swap agreements with several financial institutions for a total notional amount of $400 million to hedge a portion of our interest rate exposure associated with variability in future cash flows attributable to changes in interest rates over a ten-year period related to an anticipated issuance of debt. In connection with the issuance of the 2030 Senior Notes, these agreements were settled and we received $6 million. These gains are deferred in stockholders' equity, net of taxes, as a component of accumulated other comprehensive loss, and amortized as an adjustment to interest expense, net over a ten-year period.

For further details regarding our outstanding debt and our financial instruments and hedging activities, see Notes 13 and 15, respectively, to the audited consolidated financial statements.

Risk Associated with Investment Portfolio

Our investment portfolio includes equity investments comprised primarily of strategic equity holdings in privately and publicly held companies. These securities are exposed to price fluctuations and are generally concentrated in the life sciences and healthcare industries. Equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) with readily determinable fair values are measured at fair value with changes in fair value recognized in net income. Equity investments that do not have readily determinable fair values are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes; we regularly evaluate these equity investments to determine if there are any indicators that the investment is impaired. The carrying value of our equity investments that do not have readily determinable fair values was $25 million as of December 31, 2019.

We do not hedge our equity price risk. The impact of an adverse movement in equity prices on our holdings in privately held companies cannot be easily quantified, as our ability to realize returns on investments depends on, among other things, the enterprises’ ability to raise additional capital or derive cash inflows from continuing operations or through liquidity events such as initial public offerings, mergers or private sales.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and highly-liquid short-term investments. Cash and cash equivalents as of December 31, 2019 and 2018 totaled $1,192 million and $135 million, respectively.

As of December 31, 2019, approximately 3% of our $1,192 million of consolidated cash and cash equivalents were held outside of the United States. Our current liquidity position does not require repatriation of these funds in order to fund operations in the United States. However, as a result of changes introduced by the TCJA, we may repatriate back to the United States the portion of these foreign funds not expected to be used to maintain or expand operations (including through acquisitions) outside of the United States.

Cash Flows from Operating Activities

Net cash provided by operating activities for the year ended December 31, 2019 was $1,243 million, and increased $43 million compared to the prior year primarily as a result of:


•	lower compensation payments in 2019 compared to 2018;


•	higher operating income in 2019 as compared to 2018;


•	timing of movements in our working capital accounts; and


•	a $28 million refund from the taxing authorities associated with the favorable resolution of certain tax contingencies related to a discontinued operation; partially offset by


•	a $118 million increase in income tax payments.

Days sales outstanding, a measure of billing and collection efficiency, was 54 days as of both December 31, 2019 and 2018.

Cash Flows from Investing Activities

Net cash used in investing activities for the year ended December 31, 2019 was $411 million, compared to $801 million for the year ended December 31, 2018. This $390 million decrease in cash used in investing activities was primarily a result of a $363 million decrease in net cash paid for business acquisitions.

Cash Flows from Financing Activities

Net cash provided by financing activities for the year ended December 31, 2019 was $225 million, compared to net cash used in financing activities of $401 million for the year ended December 31, 2018. This $626 million increase in cash provided by financing activities was primarily a result of $832 million of net borrowings (proceeds from borrowing less repayments of debt) in 2019 compared to $124 million of net borrowings in 2018.

In March 2019, we completed the issuance of the 2029 Senior Notes and repaid in full, at maturity, our $300 million senior notes due April 1, 2019. In December 2019, we completed the issuance of the 2030 Senior Notes, and, in January 2020, we used the net proceeds, along with cash on hand, to redeem in full our $500 million senior notes due January 2020 and our $300 million senior notes due March 2020. In addition, during 2019 we borrowed a total of $985 million under our secured receivables credit facility to fund periodic working capital requirements as well as our 2019 acquisition and repaid $1,145 million under our secured receivables credit facility. During the year ended December 31, 2019, there were no borrowings or repayments under our senior unsecured revolving credit facility.

In 2018, there were $2,090 million in cumulative borrowings under our secured receivables credit facility primarily associated with working capital requirements as well as the funding of our 2018 acquisitions and $1,960 million in repayments. In 2018, there were no borrowings or repayments under our senior unsecured revolving credit facility.

For details regarding our debt and related transactions, see Note 13 to the audited consolidated financial statements.

Dividend Program

During each of the four quarters of 2019, our Board of Directors declared a quarterly cash dividend of $0.53 per common share. During each of the first three quarters of 2018, our Board of Directors declared a quarterly cash dividend of $0.50 per common share. During the fourth quarter of 2018, our Board of Directors declared a quarterly cash dividend of $0.53 per common share. On January 30, 2020, we announced that our Board of Directors authorized a 5.7% increase in our quarterly cash dividend from $0.53 to $0.56 per share, or $2.24 per share annually, commencing with the dividend payable in April 2020.

Share Repurchases

In November 2019, our Board of Directors authorized us to repurchase an additional $1 billion of our common stock. As of December 31, 2019, $1.2 billion remained available under the Company’s share repurchase authorization.

For the year ended December 31, 2019, we repurchased 3.5 million shares of our common stock for $350 million.

For the year ended December 31, 2018, we repurchased 3.4 million shares of our common stock for $325 million, which included an accrual of $3 million recorded in accounts payable and accrued expenses in the consolidated balance sheet for share repurchases not settled until after December 31, 2018.

For further details regarding our share repurchases, see Note 16 to the audited consolidated financial statements.

Contractual Obligations and Commitments

The following table summarizes certain of our contractual obligations as of December 31, 2019 (dollars in millions):



	Payments due by period
Contractual Obligations	Total		Less than 1 year		1-3 years		4-5 years		After 5 years

Outstanding debt	$	4,776	$	800	$	550	$	300	$	3,126
Finance lease obligations	33		3		6		3		21
Interest payments on outstanding debt	1,706		187		301		280		938

Merger consideration obligation	7		7		—		—		—
Total contractual obligations	$	8,947	$	1,506	$	1,694	$	1,177	$	4,570

Interest payments on our outstanding debt include interest associated with finance lease obligations and have been calculated after giving effect to our interest rate swap agreements, using the interest rates as of December 31, 2019 applied to the December 31, 2019 balances, which are assumed to remain outstanding through their maturity dates. A description of the terms of our indebtedness and related debt service requirements is contained in Note 13 to the audited consolidated financial statements.

Operating lease obligations include variable charges (primarily maintenance fees and utilities associated with our real estate leases) in effect as of December 31, 2019. A discussion and analysis regarding our operating lease obligations is contained in Note 14 to the audited consolidated financial statements.

Purchase obligations include our noncancelable commitments to purchase products or services as described in Note 18 to the audited consolidated financial statements.

Merger consideration obligations include consideration owed on our business acquisitions. For details regarding our acquisitions, see Note 6 to the audited consolidated financial statements.

As of December 31, 2019, our total liabilities associated with unrecognized tax benefits were approximately $88 million, which were excluded from the table above. We expect that these liabilities may decrease by up to $10 million within the next twelve months, primarily as a result of payments, settlements, expiration of statutes of limitations and/or the conclusion of tax examinations on certain tax positions. For the remainder, we cannot make reasonably reliable estimates of

Table of Contents

the timing of the future payments of these liabilities. See Note 8 to the audited consolidated financial statements for information regarding our contingent tax liability reserves.

In connection with the sale of an 18.9% noncontrolling interest in a subsidiary to UMass Memorial Medical Center ("UMass"), we granted UMass the right to require us to purchase all of its interest in the subsidiary at fair value commencing July 1, 2020. As of December 31, 2019, the fair value of the redeemable noncontrolling interest on the audited consolidated balance sheet was $76 million, which was excluded from the table above. Since the redemption of the noncontrolling interest is outside of our control, we cannot make a reasonably reliable estimate of the timing of the future payment, if any, of the redeemable noncontrolling interest. For further details regarding the redeemable noncontrolling interest, see Note 16 to the audited consolidated financial statements.

Our credit agreements contain various covenants and conditions, including the maintenance of certain financial ratios, that could impact our ability to, among other things, incur additional indebtedness. As of December 31, 2019, we were in compliance with the various financial covenants included in our credit agreements and we do not expect these covenants to adversely impact our ability to execute our growth strategy or conduct normal business operations.

Equity Method Investees

Our equity method investees primarily consist of our clinical trials central laboratory services joint venture and our diagnostic information services joint ventures, which are accounted for under the equity method of accounting. Our investment in equity method investees equals less than 5% of our consolidated total assets. Our proportionate share of income before income taxes associated with our equity method investees is less than 10% of our consolidated income from continuing operations before income taxes and equity in earnings of equity method investees. We have no material unconditional obligations or guarantees to, or in support of, our equity method investees and their operations. For further details regarding related party transactions with our equity method investees, see Note 20 to the audited consolidated financial statements.

Requirements and Capital Resources

We estimate that we will invest approximately $375 million to $400 million during 2020 for capital expenditures, to support and grow our existing operations, principally related to investments in information technology, laboratory equipment and facilities, including our new multi-year laboratory construction in New Jersey, and additional investments in our advanced diagnostics and consumer growth strategies.

In January 2020, we redeemed in full our $500 million senior notes due January 2020 and $300 million senior notes due March 2020 using cash on hand principally associated with the net proceeds from the 2030 Senior Notes offering in December.

As of December 31, 2019, $1.3 billion of borrowing capacity was available under our existing credit facilities consisting of $529 million available under our secured receivables credit facility and $750 million available under our senior unsecured revolving credit facility. The secured receivables credit facility includes a $250 million loan commitment which matures October 2020, and a $250 million loan commitment and a $100 million letter of credit facility which mature October 2021. The senior unsecured revolving credit facility matures in March 2023.

We believe the borrowing capacity under the credit facilities described above continues to be available to us. Should one or several banks no longer participate in either of our credit facilities, we would not expect it to impact our ability to fund operations. We expect that we will be able to replace our existing credit facilities with alternative arrangements prior to their expiration.

We believe that our cash and cash equivalents and cash from operations, together with our borrowing capacity under our credit facilities, will provide sufficient financial flexibility to fund seasonal and other working capital requirements, capital expenditures, debt service requirements and other obligations, cash dividends on common shares, share repurchases and additional growth opportunities for the foreseeable future. We believe that our credit profile should provide us with access to additional financing to refinance upcoming debt maturities and, if necessary, to fund growth opportunities that cannot be funded from existing sources.

Inflation

We believe that inflation generally does not have a material adverse effect on our results of operations or financial condition.

REPORT OF MANAGEMENT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of the Company, including its Chief Executive Officer and Chief Financial Officer, 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, as amended. Management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2019 based 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. Based on this assessment, management has determined that the Company's internal control over financial reporting as of December 31, 2019 is effective.

The 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 accounting principles generally accepted in the United States of America. Internal control over financial reporting includes policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States of America, and that receipts and expenditures of the Company are being made only in accordance with authorization of management and directors of the Company; and (3) 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. 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.

PricewaterhouseCoopers LLP, the independent registered public accounting firm that audited the financial statements included in this annual report, audited the Company's internal control over financial reporting as of December 31, 2019 and issued their audit report on the Company's internal control over financial reporting included herein.

We have audited the accompanying consolidated balance sheets of Quest Diagnostics Incorporated and its subsidiaries (the “Company”) as of December 31, 2019 and 2018, and the related consolidated statements of operations, comprehensive income, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2019, including the related notes and schedule of valuation accounts and reserves for each of the three years in the period ended December 31, 2019 listed in the index appearing under Item 15(a)(2) (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Change in Accounting Principle

As discussed in Note 2 to the consolidated financial statements, the Company changed the manner in which it accounts for leases in 2019.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Report of Management on Internal Control over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. 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.

Definition and Limitations of Internal Control over Financial Reporting

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

F- 1

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.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Valuation of Diagnostics Information Services (DIS) Business Accounts Receivable - Contractual Allowances

As described in Note 3 to the consolidated financial statements, management estimates the amount of consideration it expects to be entitled to receive from customer groups, using the portfolio approach, in exchange for providing services. These estimates include the impact of contractual allowances, including payer denials, and price concessions. The portfolio approach includes the following groups of customers: healthcare insurers, government payers, client payers and patients (22%, 11%, 42% and 20% of consolidated net accounts receivable as of December 31, 2019, respectively, as disclosed by management). The DIS business accounted for 95% of consolidated net accounts receivable ($1,063 million) as of December 31, 2019. Net revenues and accounts receivable recognized from healthcare insurers and government payers consist of amounts billed net of contractual allowances for differences between amounts billed and the estimated consideration the Company expects to receive from such payers, which considers historical denial and collection experience and, additionally for healthcare insurers, the terms of the Company’s contractual arrangements. As disclosed by management, the process for estimating revenues and the ultimate collection of receivables associated with the DIS business involves significant assumptions and judgments.

The principal considerations for our determination that performing procedures relating to the valuation of DIS business accounts receivable - contractual allowances is a critical audit matter are the estimate of net collectible accounts receivable, specifically contractual allowances, involves significant judgment and estimation on the part of management. This in turn led to significant auditor judgment and effort in performing procedures to evaluate the audit evidence obtained related to the contractual allowances.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the valuation of DIS business accounts receivable, which included controls over management’s methodology and data used to estimate contractual allowances. These procedures also included, among others, testing management's process for developing the estimate for contractual allowances, including evaluating the appropriateness of the methodology and testing the historical contractual allowance and collection data from the Company’s billing system, which is an input to the methodology. Additionally, the reasonableness of management’s assumptions for contractual allowances was evaluated by comparing actual cash collected to the prior year estimate (net accounts receivable).

1. DESCRIPTION OF BUSINESS

Background

Quest Diagnostics Incorporated and its subsidiaries ("Quest Diagnostics" or the "Company") empower people to take action to improve health outcomes. The Company uses its extensive database of clinical lab results to derive diagnostic insights that reveal new avenues to identify and treat disease, inspire healthy behaviors and improve healthcare management. The Company's diagnostic information services business ("DIS") provides information and insights based on the industry-leading menu of routine, non-routine and advanced clinical testing and anatomic pathology testing, and other diagnostic information services. The Company provides services to a broad range of customers, including patients, clinicians, hospitals, independent delivery networks ("IDNs"), health plans, employers and accountable care organizations ("ACOs"). The Company offers the broadest access in the United States to diagnostic information services through its nationwide network of laboratories, patient service centers and phlebotomists in physician offices and the Company's connectivity resources, including call centers and mobile paramedics, nurses and other health and wellness professionals. The Company is the world's leading provider of diagnostic information services. The Company provides interpretive consultation with one of the largest medical and scientific staffs in the industry and hundreds of M.D.s and Ph.Ds, many of whom are recognized leaders in their fields. The Company's Diagnostic Solutions businesses ("DS") are the leading provider of risk assessment services for the life insurance industry and offer healthcare organizations and clinicians robust information technology solutions.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The consolidated financial statements include the accounts of all entities controlled by the Company through its direct or indirect ownership of a majority voting interest. Additionally, the consolidated financial statements include the accounts of variable interest entities (“VIEs”) in which the Company has a variable interest and for which the Company is the “primary beneficiary” as it has both: (1) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (2) the obligation to absorb losses of the VIE that potentially could be significant to the VIE or the right to receive benefits from the VIE that potentially could be significant to the VIE. All significant intercompany accounts and transactions are eliminated in consolidation.

Income attributable to the minority interest in the Company's majority owned and controlled consolidated subsidiaries is recorded as net income attributable to noncontrolling interests in the consolidated statements of operations and the noncontrolling interest is reflected as a separate component of consolidated stockholders' equity in the consolidated balance sheets.

Basis of Presentation

During the third quarter of 2006, the Company completed the wind down of Nichols Institute Diagnostics ("NID"), a test kit manufacturing subsidiary. The accompanying consolidated statements of operations and related disclosures report the results of NID as discontinued operations for all periods presented. See Note 21 for a further discussion of discontinued operations.

Reclassifications

Certain amounts in the prior period financial statements have been reclassified to conform to the presentation of the current period financial statements.

Equity Method Investments

Investments in entities which the Company does not control, but in which it has a substantial ownership interest (generally between 20% and 49%) and can exercise significant influence, are accounted for using the equity method of accounting. These investments are classified as investments in equity method investees in the consolidated balance sheets. The Company records its pro rata share of the earnings, adjusted for accretion of basis difference, of these investments in equity in earnings of equity method investees, net of taxes in the consolidated statements of operations. The Company reviews its investments in equity method investees for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) 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 reporting period. Actual results could differ from those estimates.

Revenue Recognition

The Company primarily recognizes as revenue the amount that reflects the consideration to which it expects to be entitled in exchange for goods sold or services rendered upon completion of the testing process, when results are reported, or when services have been rendered (see Note 3). Net revenues from Medicare and Medicaid programs were approximately 15%, 16% and 17% of the Company's consolidated net revenues for the years ended December 31, 2019, 2018 and 2017, respectively.

Taxes on Income

The provision for income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Current and deferred income taxes are measured based on the tax laws that are enacted as of the balance sheet date of the relevant reporting period. Deferred tax assets and liabilities are recognized for the expected future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax bases using tax rates in effect for the year in which the differences are expected to reverse. A valuation allowance is provided when it is more likely than not that some portion or all of the deferred tax assets will not be realized. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period when the change is enacted. Tax benefits from uncertain tax positions are recognized only if the tax position is more likely than not to be sustained upon examination by taxing authorities based on the technical merits of the position.

Earnings Per Share

The Company's unvested restricted stock units that contain non-forfeitable rights to dividends are participating securities and, therefore, are included in the earnings allocation in computing earnings per share using the two-class method. Basic earnings per common share is calculated by dividing net income, adjusted for earnings allocated to participating securities, by the weighted average number of common shares outstanding. Diluted earnings per common share is calculated by dividing net income, adjusted for earnings allocated to participating securities, by the weighted average number of common shares outstanding after giving effect to all potentially dilutive common shares outstanding during the period. Potentially dilutive common shares include the dilutive effect of outstanding stock options and performance share units granted under the Company's Amended and Restated Employee Long-Term Incentive Plan (“ELTIP”) and its Amended and Restated Non-Employee Director Long-Term Incentive Plan (“DLTIP”). Earnings allocable to participating securities include the portion of dividends declared as well as the portion of undistributed earnings during the period allocable to participating securities.

Stock-Based Compensation

The Company measures stock-based compensation for equity awards at fair value on the date of grant and records stock-based compensation as a charge to earnings net of the estimated impact of forfeited awards. As such, the Company recognizes stock-based compensation cost only for those stock-based awards that are estimated to ultimately vest over their requisite service period, based on the vesting provisions of the individual grants. The cumulative effect on current and prior periods of a change in the estimated forfeiture rate is recognized as compensation cost in earnings in the period of the change. The terms of the Company's performance share unit awards allow the recipients of such awards to earn a variable number of shares based on the achievement of the performance goals specified in the awards. Stock-based compensation expense associated with performance share units is recognized based on management's best estimates of the achievement of the performance goals specified in such awards and the resulting number of shares that will be earned. The cumulative effect on current and prior periods of a change in the estimated number of performance share units expected to be earned is recognized as compensation cost in earnings in the period of the change. For further details regarding stock-based compensation, see Note 17.

Fair Value Measurements

The Company determines fair value measurements used in its consolidated financial statements based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants exclusive of any transaction costs, as determined by either the principal market or the most advantageous market.

Inputs used in the valuation techniques to derive fair values are classified based on a three-level hierarchy. The basis for fair value measurements for each level within the hierarchy is described below with Level 1 having the highest priority and Level 3 having the lowest.

Level 1: Quoted prices in active markets for identical assets or liabilities.

Level 2: Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets.

Level 3: Valuations derived from valuation techniques in which one or more significant inputs are unobservable.

Foreign Currency

The Company predominately uses the U.S. dollar as its functional currency. The functional currency of the Company's foreign operating subsidiaries generally is the applicable local currency. Assets and liabilities denominated in non-U.S. dollars are translated into U.S. dollars at exchange rates as of the end of the reporting period. Income and expense items are translated at the average monthly exchange rates during the year. Resulting translation adjustments are recorded as a component of accumulated other comprehensive loss within stockholders' equity. Gains and losses from foreign currency transactions, which are denominated in a currency other than the functional currency, are included within other operating (income) expense, net in the consolidated statements of operations. Foreign currency transaction gains and losses have historically not been material. The Company may be exposed to market risk for changes in foreign exchange rates primarily under certain intercompany receivables and payables. From time to time, the Company uses foreign exchange forward contracts to mitigate the exposure of the eventual net cash inflows or outflows resulting from these intercompany transactions. The Company's foreign exchange exposure is not material to the Company's consolidated financial condition. The Company does not hedge its net investment in non-U.S. subsidiaries because it views those investments as long-term in nature.

Cash and Cash Equivalents

Cash and cash equivalents include all highly-liquid investments with original maturities, at the time acquired by the Company, of three months or less.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk are principally cash, cash equivalents, short-term investments, accounts receivable and derivative financial instruments. The Company's policy is to place its cash, cash equivalents and short-term investments in highly-rated financial instruments and institutions. Concentration of credit risk with respect to accounts receivable is mitigated by the diversity of the Company's payers and their dispersion across many different geographic regions, and is limited to certain payers who are large buyers of the Company's services. To reduce risk, the Company routinely assesses the financial strength of these payers and, consequently, believes that its accounts receivable credit risk exposure, with respect to these payers, is limited. While the Company has receivables due from federal and state governmental agencies, the Company does not believe that such receivables represent a credit risk since the related healthcare programs are funded by federal and state governments, and payment is primarily dependent on submitting appropriate documentation. As of December 31, 2019 and 2018, receivables due from government payers under the Medicare and Medicaid programs represented approximately 11% and 13%, respectively, of the Company's consolidated net accounts receivable. The portion of the Company's accounts receivable due from patients comprises the largest portion of credit risk. As of both December 31, 2019 and 2018, receivables due from patients represented approximately 20% of the Company's consolidated net accounts receivable. The Company applies assumptions and judgments including historical collection experience (including the period the receivables have been outstanding) for assessing collectibility and determining net revenues and accounts receivable from patients.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are reported at realizable value, net of allowances for doubtful accounts, which are estimated and recorded in the period the related revenue is recorded. The Company has a standardized approach to estimate and review the collectibility of its receivables based on a number of factors, including the period they have been outstanding. Changes to the allowances for doubtful accounts estimates are recorded as an adjustment to bad debt expense within selling, general and administrative expenses in the consolidated statements of operations. Receivables deemed to be uncollectible are charged against the allowance for doubtful accounts at the time such receivables are written-off. Recoveries of receivables previously written-off are recorded as credits to the allowance for doubtful accounts.

Inventories

Inventories, which consist principally of finished goods testing supplies and reagents, are valued at the lower of cost (first in, first out method) or net realizable value.

Property, Plant and Equipment

Property, plant and equipment is recorded at cost. Major renewals and improvements are capitalized, while maintenance and repairs are expensed as incurred. Costs incurred for computer software developed or obtained for internal use are capitalized for application development activities and expensed as incurred for preliminary project activities and post-implementation activities. Capitalized costs include external direct costs of materials and services consumed in developing or obtaining internal-use software, payroll and payroll-related costs for employees who are directly associated with the internal-use software project, and interest costs incurred, when material, while developing internal-use software. Capitalization of such costs ceases when the project is substantially complete and ready for its intended purpose. Costs for maintenance and training are expensed as incurred. The Company capitalizes interest on borrowings during the active construction period of major capital projects. Capitalized interest is added to the cost of the underlying assets and is amortized over the expected useful lives of the assets. Depreciation and amortization are provided on the straight-line method over expected useful asset lives as of December 31, 2019 as follows:


•	buildings and improvements, ranging up to thirty-one and a half years;


•	laboratory equipment and furniture and fixtures, ranging from five to twelve years;


•	leasehold improvements, the lesser of the useful life of the improvement or the remaining life of the building or lease, as applicable; and


•	computer software developed or obtained for internal use, five to ten years.

Goodwill

Goodwill represents the excess of the fair value of the acquiree (including the fair value of non-controlling interests) over the recognized bases of the net identifiable assets acquired and includes the future economic benefits from other assets that could not be individually identified and separately recognized. Goodwill is not amortized, but instead is periodically reviewed for impairment and an impairment charge is recorded in the periods in which the recorded carrying value of goodwill exceeds its fair value.

The goodwill test is performed at least annually, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The annual impairment test includes an option to perform a qualitative assessment of whether it is more likely than not that a reporting unit's fair value is less than its carrying value; the qualitative test may be performed prior to, or as an alternative to, performing a quantitative goodwill impairment test. If, after assessing the totality of events or circumstances, the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying value, then the Company is required to perform the quantitative goodwill impairment test. Otherwise, no further analysis is required. Additionally, the Company's policy is to update the fair value calculation of its reporting units and perform the quantitative goodwill impairment test on a periodic basis.

The quantitative impairment test involves the comparison of the fair value of the reporting unit to its carrying value. The Company calculates the fair value of each reporting unit using either a discounted cash flows analysis that converts future cash flow amounts into a single discounted present value amount or a market approach. The Company assesses the valuation methodology based upon the relevance and availability of the data at the time that the valuation is performed. The Company compares the estimate of fair value for the reporting unit to the carrying value of the reporting unit. If the carrying value is greater than the estimate of fair value, an impairment loss will be recognized in the amount of the excess.

On a quarterly basis, the Company performs a review of its business to determine if events or changes in circumstances have occurred which could have a material adverse effect on the fair value of the Company and its goodwill. If such events or changes in circumstances were deemed to have occurred, the Company would perform an impairment test of goodwill as of the end of the quarter and record any noted impairment loss.

The Company performs its annual impairment test during the fourth quarter of the fiscal year. For the year ended December 31, 2019 and 2018, the Company performed the qualitative assessment for its DIS and risk assessment services reporting units. Based on the totality of information available for the DIS and risk assessment services reporting units, the Company concluded that it was more likely than not that the estimated fair values were greater than the carrying values of the reporting units, and as such, no further analysis was required.

Intangible Assets

Intangible assets are recognized at fair value, as an asset apart from goodwill if the asset arises from contractual or other legal rights, or if it is separable. Intangible assets, principally representing the cost of customer-related intangibles, non-competition agreements and technology acquired, are capitalized and amortized on the straight-line method over their expected useful life, which generally ranges from five to twenty years. Intangible assets with indefinite useful lives, consisting principally of acquired tradenames, are not amortized, but instead are periodically reviewed for impairment.

F- 12

Table of Contents

QUEST DIAGNOSTICS INCORPORATED AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – CONTINUED

(in millions unless otherwise indicated)

The Company reviews indefinite-lived intangible assets periodically for impairment and an impairment charge is recorded in the periods in which the recorded carrying value of indefinite-lived intangibles is more than its estimated fair value. The indefinite-lived intangible asset impairment test is performed at least annually, or more frequently in the case of other events that indicate a potential impairment.

Based upon the Company’s most recent annual impairment tests completed during the fourth quarter of the years ended December 31, 2019 and 2018, the Company concluded that indefinite-lived intangible assets were not impaired.

The Company reviews the recoverability of its long-lived assets (including amortizable intangible assets), other than goodwill and indefinite-lived intangible assets, when events or changes in circumstances occur that indicate that the carrying value of the asset may not be recoverable. Evaluation of possible impairment is based on the Company's ability to recover the asset from the expected future pre-tax cash flows (undiscounted and without interest charges) of the related operations. If the expected undiscounted pre-tax cash flows are less than the carrying amount of such asset, an impairment loss is recognized for the difference between the estimated fair value and carrying amount of the asset.

Investments

The Company's investments (except for those accounted for under the equity method of accounting), are included in other assets in the consolidated balance sheets and include:

•

Equity investments with readily determinable fair values which are comprised of participant-directed investments of deferred employee compensation and related Company matching contributions held in trusts pursuant to the Company's supplemental deferred compensation plans (see Note 17). These investments are measured at fair value with both realized and unrealized gains and losses recorded in current earnings within other income (expense), net in the consolidated statements of operations. For the years ended December 31, 2019, 2018 and 2017, gains and (losses) from these equity securities totaled $10 million, $(2) million, and $8 million, respectively. The carrying value of these investments were $59 million and $53 million at December 31, 2019 and 2018, respectively.

•

Equity investments that do not have readily determinable fair values which consist of investments in preferred and common shares of privately held companies. These investments are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes. The Company regularly evaluates these equity investments to determine if there are any indicators that the investment is impaired; no impairment charges were recognized related to these investments for the years ended December 31, 2019, 2018, and 2017. The carrying value of these investments were $25 million and $10 million at December 31, 2019 and 2018, respectively.


•	Available-for-sale debt securities of privately-held companies. These investments are measured at fair value with unrealized gains and losses presented in other comprehensive income. The carrying amount of these investments was $12 million and $0 million at December 31, 2019 and 2018, respectively.

Derivative Financial Instruments

The Company uses derivative financial instruments to manage its exposure to market risks for changes in interest rates and, from time to time, foreign currencies. This strategy includes the use of interest rate swap agreements, forward-starting interest rate swap agreements, treasury lock agreements and foreign currency forward contracts to manage its exposure to movements in interest and currency rates. The Company has established policies and procedures for risk assessment and the approval, reporting and monitoring of derivative financial instrument activities. These policies prohibit holding or issuing derivative financial instruments for speculative purposes. The Company does not enter into derivative financial instruments that contain credit risk-related contingent features or requirements to post collateral.

(in millions unless otherwise indicated)

Interest Rate Risk

The Company is exposed to interest rate risk on its cash and cash equivalents and its debt obligations. Interest income earned on cash and cash equivalents may fluctuate as interest rates change; however, due to their relatively short maturities, the Company does not hedge these assets or their investment cash flows and the impact of interest rate risk is not material. The Company's debt obligations consist of fixed-rate and variable-rate debt instruments. The Company's primary objective is to achieve the lowest overall cost of funding while managing the variability in cash outflows within an acceptable range. In order to achieve this objective, the Company has entered into interest rate swaps. Interest rate swaps involve the periodic exchange of payments without the exchange of underlying principal or notional amounts. Net settlements between the counterparties are recognized as an adjustment to interest expense, net.

The Company accounts for these derivatives as either an asset or liability measured at its fair value. The fair value is based upon model-derived valuations in which all significant inputs are observable in active markets and includes an adjustment for the credit risk of the obligor's non-performance. For a derivative instrument that has been formally designated as a fair value hedge, fair value gains or losses on the derivative instrument along with offsetting fair value gains or losses on the hedged item that are attributable to the risk being hedged are reported in other income (expense), net in the consolidated statements of operations. For derivatives that have been formally designated as a cash flow hedge, the change in the fair value of the derivatives is recorded in accumulated other comprehensive loss. Upon maturity or early termination of an effective interest rate swap designated as a cash flow hedge, unrealized gains or losses are deferred in stockholders' equity, as a component of accumulated other comprehensive loss, and are amortized as an adjustment to interest expense over the period during which the hedged forecasted transaction affects earnings, which is when the Company recognizes interest expense on the hedged cash flows. At inception and quarterly thereafter, the Company formally assesses whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in the fair value or cash flows of the hedged item. After the initial quantitative assessment, this analysis is performed on a qualitative basis and, if it is determined that the hedging relationship was and continues to be highly effective, no further analysis is required. All components of each derivative financial instrument's gain or loss are included in the assessment of hedge effectiveness. If it is determined that a derivative ceases to be a highly effective hedge, the Company discontinues hedge accounting and any deferred gains or losses related to a discontinued cash flow hedge shall continue to be reported in accumulated other comprehensive loss, unless it is probable that the forecasted transaction will not occur. If it is probable that the forecasted transaction will not occur by the originally specified time period, the Company discontinues hedge accounting, and any deferred gains or losses reported in accumulated other comprehensive loss are classified into earnings immediately.

Comprehensive Income (Loss)

Comprehensive income (loss) encompasses all changes in stockholders' equity (except those arising from transactions with stockholders) and includes:


•	Foreign currency translation adjustments;


•	Investment adjustments, which represent unrealized holding gains (losses), net of tax on available for sale debt securities; and


•	Net deferred gains (losses) on cash flow hedges, which represents deferred gains (losses), net of tax, on interest rate related derivative financial instruments designated as cash flow hedges, net of amounts reclassified to interest expense (see Note 15 and 16).

Prior to adoption of the new accounting guidance on recognition and measurement of financial assets and liabilities in 2018, investment adjustments also included unrealized holding gains (losses), net of tax, on available-for-sale equity securities, net of other-than-temporary impairment amounts reclassified to other income (expense), net.

New Accounting Standards

Adoption of New Accounting Standards

On January 1, 2019, the Company adopted a new accounting standard issued by the Financial Accounting Standards Board ("FASB") on accounting for leases using the modified retrospective method. This new accounting standard requires a lessee to recognize on its balance sheet an asset and liability for most leases. The Company elected the optional transition method that allowed for a cumulative-effect adjustment to the opening balance of retained earnings recorded on January 1, 2019

F- 14

Table of Contents

QUEST DIAGNOSTICS INCORPORATED AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – CONTINUED

(in millions unless otherwise indicated)

and did not restate previously reported results in the comparative periods. The Company also elected the package of practical expedients, which among other things, allowed it to carry forward its historical lease classification.

As a result of adoption of the new standard, the Company recorded operating lease assets and lease liabilities of approximately $500 million and $550 million, respectively as of January 1, 2019. The operating lease liability was determined based on the present value of the remaining minimum rental payments and the operating lease asset was determined based on the value of the lease liability, adjusted for the deferred rent balances of approximately $50 million, which were previously included in accounts payable and accrued expenses as well as other liabilities. Accounting for the Company's finance leases remains substantially unchanged. The adoption of the new standard did not materially impact the Company's consolidated results of operations or cash flows.

In addition, the adoption of this new accounting standard resulted in increased qualitative and quantitative disclosures regarding the amount, timing, and uncertainty of cash flows arising from leases. For further details, see Note 14.

On January 1, 2019, the Company adopted a new accounting standard issued by the FASB that includes the overnight index swap rate based on the Secured Overnight Financing Rate as an additional benchmark interest rate for hedge accounting purposes. Adoption of this new accounting standard applies prospectively to new or redesignated hedges entered into after the adoption date and, therefore, did not have an impact on the Company's existing interest rate swap agreements.

New Accounting Standards To Be Adopted

In August 2018, the FASB issued an Accounting Standard Update (“ASU”) that aligns the requirements for deferring implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This ASU is effective for the Company in the first quarter of 2020 and can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The adoption of this standard, which the Company expects to do on a prospective basis, is not expected to have a material impact on the Company’s results of operations, financial position or cash flows.

In June 2016, the FASB issued an ASU that changes the impairment model for most financial instruments, including trade receivables, from an incurred loss method to a new forward-looking approach, based on expected losses. The estimate of expected credit losses will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. This ASU is effective for the Company in the first quarter of 2020 and must be adopted using a modified retrospective transition approach. The adoption of this standard is not expected to have a material impact on the Company’s results of operations, financial position or cash flows.

3. REVENUE RECOGNITION

DIS

Net revenues in the Company’s DIS business accounted for greater than 95% of the Company’s total net revenues for the years ended December 31, 2019, 2018 and 2017 and are primarily comprised of a high volume of relatively low-dollar transactions. The DIS business, which provides clinical testing services and other services, satisfies its performance obligation and recognizes revenues upon completion of the testing process, when results are reported, or when services have been rendered. The Company estimates the amount of consideration it expects to be entitled to receive from customer groups, using the portfolio approach, in exchange for providing services. These estimates include the impact of contractual allowances, including payer denials, and price concessions, as discussed below. The portfolios determined using the portfolio approach consist of the following groups of customers: healthcare insurers, government payers, client payers and patients. Contracts with customers in the DIS business do not contain significant financing components based on the typical period of time between performance of services and collection of consideration.

The process for estimating revenues and the ultimate collection of accounts receivable involves significant judgment and estimation. The Company follows a standard process, which considers historical denial and collection experience and other factors (including the period the receivables have been outstanding), to estimate contractual allowances and implicit price concessions, recording adjustments in the current period as changes in estimates. Further adjustments to the allowances, based on actual receipts, may be recorded upon settlement. Based on this process, during the fourth quarter of 2018, the Company

F- 15

Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – CONTINUED

(in millions unless otherwise indicated)

increased its reserves for revenues and accounts receivable by approximately $35 million due to an increase in denials and a shift toward higher patient responsibility throughout the year.

The following are descriptions of the DIS business’ portfolios:

Healthcare Insurers

Reimbursements from healthcare insurers are based on negotiated fee-for-service schedules and on capitated payment rates. Under fee-for-service arrangements, healthcare insurers are billed at the Company's list price. Net revenues recognized consist of amounts billed net of contractual allowances for differences between amounts billed and the estimated consideration the Company expects to receive from such payers, which considers historical denial and collection experience and the terms of the Company’s contractual arrangements.

Collection of the Company's net revenues from healthcare insurers is normally a function of providing complete and correct billing information to the healthcare insurers within the various filing deadlines and generally occurs within 30 to 60 days of billing. Provided the Company has billed healthcare insurers accurately with complete information prior to the established filing deadline, there has historically been little to no credit risk. If there has been a delay in billing, the Company determines if the amounts in question will likely go past the filing deadline, and if so, it will reserve accordingly for the billing.

Under capitated arrangements with healthcare insurers, the Company recognizes revenue based on a predetermined monthly reimbursement rate for each member of an insurer's health plan regardless of the number or cost of services provided by the Company. Healthcare insurers typically reimburse the Company under capitated arrangements in the same month services are performed, essentially giving rise to no outstanding accounts receivable at the end of a reporting period. If any capitated payments are not received on a timely basis, the Company determines the cause and makes a separate determination as to whether or not the collection of the amount from the healthcare insurer is at risk and, if so, would reserve accordingly.

Government Payers

Reimbursements from government payers are based on fee-for-service schedules set by governmental authorities, including traditional Medicare and Medicaid. Net revenues recognized consist of amounts billed net of contractual allowances for differences between amounts billed and the estimated consideration the Company expects to receive from such payers, which considers historical denial and collection experience and other factors.

Collection of the Company's net revenues from government payers is normally a function of providing the complete and correct billing information within the various filing deadlines and generally occurs within 30 days of billing. Provided the Company has billed government payers accurately with complete information prior to the established filing deadline, there has historically been little to no credit risk. If there has been a delay in billing, the Company determines if the amounts in question will likely go past the filing deadline, and, if so, it will reserve for the billing accordingly.

Client Payers

Client payers include physicians, hospitals, ACOs, IDNs, employers, other commercial laboratories and institutions for which services are performed on a wholesale basis, and are billed based on negotiated fee schedules. Credit risk and ability to pay are more of a consideration for these payers than healthcare insurers and government payers. Collection of consideration the Company expects to receive generally occurs within 60 to 90 days of billing. In addition to our standard approach to establishing allowances for doubtful accounts (which considers a number of factors including the period the receivables have been outstanding), our approach to client payer receivables also focuses on specific account reviews, historical collection experience and other factors.

Patients

(in millions unless otherwise indicated)

consideration the Company expects to receive from patients, which considers historical collection experience (including the period the receivables have been outstanding) and other factors including current market conditions. Patient billings are generally fully reserved for when the related billing reaches 210 days outstanding. Balances are automatically written off when they are sent to collection agencies. Allowances are further adjusted for estimated recoveries of amounts sent to collection agencies based on historical collection experience, which is regularly monitored. Collection of consideration the Company expects to receive generally occurs within 30 to 60 days of billing.

The Company’s DS businesses primarily satisfy their performance obligations and recognize revenues when delivery has occurred or services have been rendered. Collection of consideration the Company expects to receive generally occurs within 30 to 60 days of billing.

The approximate percentage of net revenue by type of customer was as follows:



	Twelve Months Ended December 31,
	2019		2018		2017
Healthcare insurers:
Fee-for-service	33	%	32	%	34	%

5. RESTRUCTURING ACTIVITIES

Invigorate Program

The Company is committed to a program called Invigorate which is designed to reduce its cost structure and improve performance. Invigorate consists of several flagship programs, with structured plans in each, to drive savings and improve performance across the customer value chain. These flagship programs include: organization excellence; information technology excellence; procurement excellence; service excellence; lab excellence; and revenue services excellence. In addition to these programs, the Company identified key themes to change how it operates including reducing denials and patient concessions; further digitizing the business; standardization and automation; and optimization initiatives in the areas of lab network and patient service center network. The Invigorate program is intended to partially offset reimbursement pressures

and labor and benefit cost increases; free up additional resources to invest in science, innovation and other growth initiatives; and enable the Company to improve service quality and operating profitability.

Restructuring Charges

The following table provides a summary of the Company's pre-tax restructuring charges for the years ended December 31, 2019, 2018 and 2017:



	2019			2018		2017

Facility-related costs	1			4		1
Asset impairment charges	—			2		3
Total restructuring charges	$	(2	)	$	51	$	33

The restructuring activity incurred for the year ended December 31, 2019 primarily represents a release of the liability relating to restructuring charges recorded in prior periods, which were determined to no longer be required. The restructuring charges incurred for the years ended December 31, 2018 and 2017 were primarily associated with various workforce reduction initiatives as the Company continued to simplify and restructure its organization. The $(2) million of restructuring charges recognized during the year ended December 31, 2019 were recorded in selling, general and administrative expenses. Of the total restructuring charges incurred during the year ended December 31, 2018, $22 million and $29 million were recorded in cost of services and selling, general and administrative expenses, respectively. Of the total restructuring charges incurred during the year ended December 31, 2017, $11 million and $22 million were recorded in cost of services and selling, general and administrative expenses, respectively.

Charges for all periods presented were primarily recorded in the Company's DIS business.

The following table summarizes the activity of the restructuring liability during 2019 and 2018, which is included in accrued expenses in Note 12:



	Employee Separation Costs			Facility-Related Costs			Total

6. BUSINESS ACQUISITIONS

2019 Acquisitions

During 2019, the Company completed acquisitions for an aggregate purchase price of $63 million, including the acquisition discussed below. The 2019 acquisitions resulted in goodwill of $43 million, of which $36 million is deductible for tax purposes. These acquisitions also resulted in $21 million of intangible assets, principally comprised of customer-related intangibles.

Acquisition of the Clinical Laboratory Services Business of Boyce & Bynum Pathology Laboratories, P.C.

On February 11, 2019, the Company completed its acquisition of certain assets of the clinical laboratory services business of Boyce & Bynum Pathology Laboratories, P.C. ("Boyce & Bynum") in an all cash transaction for $61 million, which consisted of cash consideration of $55 million and contingent consideration initially estimated at $6 million. The contingent consideration arrangement is dependent upon the achievement of certain testing volume benchmarks. During 2019, the liability was reduced to $0 as a result of updated testing volume forecasts for the earn-out period compared to the testing volume target included in the contingent consideration arrangement, resulting in a $6 million gain recorded in other operating (income) expense, net. Based on the purchase price allocation, the assets acquired principally consist of $41 million of goodwill (of which $35 million is tax deductible) and $20 million of customer-related intangible assets. The intangible assets will be amortized over a useful life of 15 years. For further details regarding the fair value of the contingent consideration, see Note 7.

2018 Acquisitions

During 2018, the Company completed acquisitions for an aggregate purchase price of $440 million, net of cash acquired, including the acquisitions discussed below. The 2018 acquisitions resulted in goodwill of $241 million, of which $205 million is deductible for tax purposes. These acquisitions also resulted in $167 million of intangible assets, principally comprised of customer-related intangibles. Net revenues attributable to the 2018 acquisitions were $84 million for the year ended December 31, 2018.

Acquisition of Mobile Medical Examination Services, LLC.

On February 1, 2018, the Company completed its acquisition of Mobile Medical Examination Services, LLC. ("MedXM"), in an all cash transaction for $142 million, net of $5 million cash acquired, which consisted of cash consideration of $130 million and contingent consideration estimated at $12 million. The contingent consideration arrangement is dependent upon the achievement of certain revenue targets. Subsequent to the acquisition, the estimated fair value of the contingent consideration was reduced to $0 as a result of updated revenue forecasts for 2018 compared to the earn-out revenue target included in the contingent consideration arrangement, resulting in a $12 million net gain recorded in other operating (income) expense, net. MedXM is a leading national provider of home-based health risk assessments and related services. Through the acquisition, the Company acquired all of MedXM's operations. The assets acquired and liabilities assumed consist of $77 million of intangible assets, $57 million of goodwill (of which $45 million is tax deductible), $7 million of working capital and $1 million of property, plant and equipment. The intangible assets consist primarily of customer related assets which are being amortized over a useful life of 15 years.

Acquisition of the Outreach Laboratory Services Business of Cape Cod Healthcare, Inc.

On June 18, 2018, the Company completed the acquisition of the outreach laboratory services business of Cape Cod Healthcare, Inc., in an all cash transaction for $35 million. The assets acquired principally consist of tax deductible goodwill and customer-related intangible assets.

Acquisition of ReproSource, Inc.

On September 19, 2018, the Company completed the acquisition of ReproSource, Inc. ("ReproSource"), in an all cash transaction for $35 million, which consisted of cash consideration of $30 million and contingent consideration estimated at $5 million. The contingent consideration arrangement is dependent upon the achievement of certain revenue targets.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following table provides a summary of the recognized assets and liabilities that are measured at fair value on a recurring basis:



			Basis of Fair Value Measurements

The Company offers certain employees the opportunity to participate in a non-qualified supplemental deferred compensation plan. A participant's deferrals, together with Company matching credits, are invested in a variety of participant-directed stock and bond mutual funds that are classified as trading securities. The trading securities are classified within Level 1 of the fair value hierarchy because the changes in the fair value of these securities are measured using quoted prices in active markets based on the market price per unit multiplied by the number of units held, exclusive of any transaction costs. A corresponding adjustment for changes in fair value of the trading securities is also reflected in the changes in fair value of the deferred compensation obligation. The deferred compensation liabilities are classified within Level 2 of the fair value hierarchy because their inputs are derived principally from observable market data by correlation to the trading securities.

The Company offers certain employees the opportunity to participate in a non-qualified deferred compensation program. A participant's deferrals, together with Company matching credits, are “invested” at the direction of the employee in a hypothetical portfolio of investments which are tracked by an administrator. The Company purchases life insurance policies, with the Company named as beneficiary of the policies, for the purpose of funding the program's liability. Changes in the cash surrender value of the life insurance policies are based upon earnings and changes in the value of the underlying investments.

(in millions unless otherwise indicated)

Changes in the fair value of the deferred compensation 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 deferred compensation obligation are classified within Level 2 of the fair value hierarchy because their inputs are derived principally from observable market data by correlation to the hypothetical investments. Deferrals under the plan currently may only be made by participants who made deferrals under the plan in 2017.

The Company's available-for-sale debt securities are measured at fair value using discounted cash flows. These fair value measurements are classified within Level 3 of the fair value hierarchy as the fair value is based on significant inputs that are not observable. Significant inputs include cash flows projections and a discount rate.

The fair value measurements of the Company's fixed-to-variable interest rate swaps classified within Level 2 of the fair value hierarchy, are model-derived valuations as of a given date in which all significant inputs are observable in active markets including certain financial information and certain assumptions regarding past, present and future market conditions.

In connection with previous business acquisitions, the Company has contingent consideration obligations that are to be paid based on the achievement of certain testing volume or revenue benchmarks. As of December 31, 2019, the fair value of these contingent consideration liabilities totaled $7 million. These contingent consideration liabilities are measured at fair value using an option-pricing method and are classified within Level 3 of the fair value hierarchy as the fair value is determined based on significant inputs that are not observable. Significant inputs include management’s estimate of volume or revenue and other market inputs including comparable company revenue volatility and a discount rate. A summary of the significant inputs is as follows:



Business Acquisition	Benchmark	Comparable Company Revenue Volatility	Discount rate	Maximum Contingent Consideration Payment

Shiel	Volume	6.9%	4.5%	$	15
ReproSource	Revenue	8.5%	6.5%	$	10
Boyce & Bynum	Volume	8.0%	7.2%	$	25

The following table provides a reconciliation of the beginning and ending balances of liabilities using significant unobservable inputs (Level 3):



	Contingent Consideration

Balance, December 31, 2017	$	7
Purchases, additions and issuances	19
Settlements	(1		)

Purchases, additions and issuances	6
Settlements	(1		)
Total (gains)/losses included in earnings - realized/unrealized	(12		)

The $12 million and $11 million net gains included in earnings associated with the changes in the fair value of contingent consideration for the years ended December 31, 2019 and 2018, respectively, is reported in other operating (income) expense, net.

In connection with the sale of an 18.9% noncontrolling interest in a subsidiary to UMass Memorial Medical Center ("UMass") on July 1, 2015, the Company granted UMass the right to require the Company to purchase all of its interest in the subsidiary at fair value commencing July 1, 2020. As of December 31, 2019, the redeemable noncontrolling interest was presented at its fair value. The fair value measurement of the redeemable noncontrolling interest is classified within Level 3 of the fair value hierarchy because the fair value is based on a discounted cash flow analysis that takes into account, among other

items, the joint venture's expected future cash flows, long term growth rates, and a discount rate commensurate with economic risk.

The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable and accrued expenses approximate fair value based on the short maturities of these instruments. As of December 31, 2019 and 2018, the fair value of the Company’s debt was estimated at $5.1 billion and $4.0 billion, respectively. Principally all of the Company's debt is classified within Level 1 of the fair value hierarchy because the fair value of the debt is estimated based on rates currently offered to the Company with identical terms and maturities, using quoted active market prices and yields, taking into account the underlying terms of the debt instruments.

8. TAXES ON INCOME

The Company's pre-tax income from continuing operations before equity in earnings of equity method investees consisted of approximately $1.1 billion, $0.9 billion and $1.0 billion from U.S. operations and pre-tax income (loss) of $15 million, $(1) million and $(7) million from foreign operations for the years ended December 31, 2019, 2018 and 2017, respectively.

The Company recognized the income tax effects of the Tax Cut and Jobs Act ("TCJA") in its 2017 consolidated financial statements in accordance with Staff Accounting Bulletin No. 118, which provides Securities and Exchange Commission staff guidance for the application of Accounting Standards Codification Topic 740, Income Taxes, in the reporting period in which the TCJA was signed into law. As such, the Company’s 2017 financial results reflected the provisional estimate of the income tax effects of the TCJA.

During the year ended December 31, 2017, the Company recorded a provisional estimated income tax benefit of $106 million associated with the TCJA, including a deferred income tax benefit of $115 million primarily due to the remeasurement of net deferred tax liabilities and reserves at the new combined federal and state tax rate, partially offset by $9 million of current tax expense primarily due to the mandatory repatriation toll charge on undistributed foreign earnings and profits. The Company did not identify items for which the income tax effects of the TCJA had not been completed and a reasonable estimate could not be determined as of December 31, 2017. During the year ended December 31, 2018, the Company finalized the effect of the enactment of TCJA and recorded an additional $1 million of current income tax expense.

As a result of the TCJA, the Company changed its assertion that it intends to indefinitely reinvest undistributed earnings from certain non-U.S. subsidiaries outside the U.S. The Company is indefinitely reinvested in the remaining basis difference and it is not practicable to determine the associated amount of unrecognized deferred tax liability.

The components of income tax expense (benefit) for 2019, 2018 and 2017 were as follows:



	2019			2018			2017
Current:
Federal	$	176		$	82		$	226
State and local	53			26			5
Foreign	3			1			1

A reconciliation of the federal statutory rate to the Company's effective tax rate for 2019, 2018 and 2017 was as follows:

Other, net	(0.6	)	—		(0.5	)
Effective tax rate	23.0	%	19.7	%	23.4	%

For the year ended December 31, 2019, the Company recognized a $12 million net income tax benefit due to the release of valuation allowances associated with certain net operating loss carryforwards. In 2018, the Company filed for a tax return accounting method change, effective for the tax year ending December 31, 2017, to accelerate the deduction of certain expenses on its 2017 tax return at the higher 2017 federal corporate statutory income rate, resulting in a $15 million income tax benefit. The net income tax benefit associated with changes in reserves for uncertain tax positions in 2018 was primarily related to the expiration of the statute of limitations for certain income tax returns.

The tax effects of temporary differences that give rise to significant portions of the deferred tax assets (liabilities) as of December 31, 2019 and 2018 were as follows:



	2019			2018
Non-current deferred tax assets (liabilities):
Accounts receivable reserves	$	64		$	66
Liabilities not currently deductible	126			137
Stock-based compensation	35			38
Basis differences in investments, joint ventures and subsidiaries	(80		)	(80		)
Net operating loss carryforwards, net of valuation allowance	75			80
Depreciation and amortization	(484		)	(484		)
Total non-current deferred tax liabilities, net	$	(264	)	$	(243	)

As of December 31, 2019 and 2018, non-current deferred tax liabilities of $264 million and $243 million, respectively, are included in other liabilities.

As of December 31, 2019, the Company had estimated net operating loss carryforwards for federal and state income tax purposes of $92 million and $1.1 billion, respectively, which expire at various dates through 2039. Estimated net operating loss carryforwards for foreign income tax purposes are $49 million as of December 31, 2019, some of which can be carried forward indefinitely while others expire at various dates through 2039. As of December 31, 2019 and 2018, deferred tax assets associated with net operating loss carryforwards of $101 million and $126 million, respectively, have each been reduced by valuation allowances of $26 million and $46 million, respectively.

Income taxes payable, including those classified as long-term in other liabilities as of December 31, 2019 and 2018, were $113 million and $85 million, respectively. Prepaid income taxes were $3 million and $14 million as of December 31, 2019 and 2018, respectively, and were recorded in prepaid expenses and other current assets.

The total amount of unrecognized tax benefits as of and for the years ended December 31, 2019, 2018 and 2017 consisted of the following:



	2019			2018			2017

Balance, beginning of year	$	107		$	115		$	98
Additions:
For tax positions of current year	2			2			5
For tax positions of prior years	16			11			23
Reductions:
Changes in judgment	(3		)	(6		)	(2		)
Expirations of statutes of limitations	(2		)	(15		)	(6		)
Settlements	(32		)	—			(3		)
Balance, end of year	$	88		$	107		$	115

The contingent liabilities for tax positions primarily relate to uncertainties associated with the realization of tax benefits derived from the allocation of income and expense among state jurisdictions, the characterization and timing of certain tax deductions associated with business combinations, income and expenses associated with certain intercompany licensing arrangements, certain tax credits and the deductibility of certain settlement payments.

The total amount of unrecognized tax benefits as of December 31, 2019, that, if recognized, would affect the effective income tax rate is $72 million. Based upon the expiration of statutes of limitations, settlements and/or the conclusion of tax examinations, the Company believes it is reasonably possible that the total amount of unrecognized tax benefits may decrease by up to $10 million within the next twelve months.

Accruals for interest expense on contingent tax liabilities are classified in income tax expense in the consolidated statements of operations. Accruals for penalties have historically been immaterial. Interest expense included in income tax expense in each of the years ended December 31, 2019, 2018 and 2017 was approximately $5 million, $1 million and $1 million, respectively. As of December 31, 2019 and 2018, the Company has approximately $17 million and $14 million, respectively, accrued, net of the benefit of a federal and state deduction, for the payment of interest on uncertain tax positions.

The recognition and measurement of certain tax benefits includes estimates and judgment by management and inherently involves subjectivity. Changes in estimates may create volatility in the Company's effective tax rate in future periods and may be due to settlements with various tax authorities (either favorable or unfavorable), the expiration of the statute of limitations on some tax positions and obtaining new information about particular tax positions that may cause management to change its estimates.

In the regular course of business, various federal, state, local and foreign tax authorities conduct examinations of the Company's income tax filings and the Company generally remains subject to examination until the statute of limitations expires for the respective jurisdiction. The Internal Revenue Service has either completed its examinations of the Company's consolidated federal income tax returns or the statute of limitations has expired up through and including the 2014 tax year. At this time, the Company does not believe that there will be any material additional payments beyond its recorded contingent liability reserves that may be required as a result of these tax audits. As of December 31, 2019, a summary of the tax years that remain subject to examination, awaiting approval, are under appeal, or are otherwise unresolved for the Company's major jurisdictions are:

United States - federal 2015 - 2019

Secured Receivables Credit Facility

On October 25, 2019, the Company amended the agreement for its $600 million secured receivables credit facility (the “Secured Receivables Credit Facility”) previously amended in October 2018, maintaining the borrowing capacity under the facility at $600 million. Under the Secured Receivables Credit Facility, the Company can borrow against a $250 million loan commitment maturing October 2020, and a $250 million loan commitment maturing October 2021, and can issue up to $100 million of letters of credit (see Note 18) through October 2021. Borrowings under the Secured Receivables Credit Facility are collateralized by certain domestic receivables. As of December 31, 2019, interest on the borrowings under the Secured Receivables Credit Facility is based on either commercial paper rates for highly-rated issuers or LIBOR plus a spread of 0.70% to 0.725%. The Secured Receivables Credit Facility contains various covenants which could impact the Company's ability to, among other things, incur additional indebtedness. As of December 31, 2019 and 2018, there was $0 million and $160 million, respectively, of outstanding borrowings under the Secured Receivables Credit Facility.

Senior Unsecured Revolving Credit Facility

In March 2018, the Company amended and restated the agreement for its $750 million senior unsecured revolving credit facility (the “Credit Facility” or "Senior Unsecured Revolving Credit Facility"). As a result, the Credit Facility will mature in March 2023. Under the Credit Facility, the Company can issue letters of credit totaling $150 million (see Note 18). Issued letters of credit reduce the available borrowing capacity under the facility. Interest on the Credit Facility is based on certain published rates plus an applicable margin based on changes in the Company's public debt ratings. At the option of the Company, it may elect to lock into LIBOR-based interest rates for periods up to six months. Interest on any outstanding amounts not covered under LIBOR-based interest rate contracts is based on an alternate base rate, which is calculated by reference to the prime rate, the federal funds rate or an adjusted LIBOR rate. As of both December 31, 2019 and 2018, the Company's borrowing rate for LIBOR-based loans under the Credit Facility was LIBOR plus 1.125%. The Credit Facility contains various covenants, including the maintenance of a financial leverage ratio, which could impact the Company's ability to, among other things, incur additional indebtedness. As of both December 31, 2019 and 2018, there were no outstanding borrowings under the Credit Facility.

March 2019 Senior Notes Offering

In March 2019, the Company completed a senior notes offering, consisting of $500 million aggregate principal amount of 4.20% senior notes due June 2029 (the "2029 Senior Notes"), which were issued at an original issue discount of $1 million. The Company incurred $5 million of debt issuance costs associated with the 2029 Senior Notes, which is included as a reduction to the carrying amount of long-term debt and is being amortized over the term of the related debt.

The net proceeds from the 2029 Senior Notes were used to repay in full the outstanding indebtedness under the Company's Senior Notes due April 2019, to repay outstanding indebtedness under the Secured Receivables Credit Facility and for general corporate purposes.

December 2019 Senior Notes Offering

In December 2019, the Company completed a senior notes offering, consisting of $800 million aggregate principal amount of 2.95% senior notes due June 2030 (the "2030 Senior Notes"), which were issued at an original issue discount of $2 million. The Company incurred $7 million of debt issuance costs associated with the 2030 Senior Notes, which is included as a reduction to the carrying amount of long-term debt and is being amortized over the term of the related debt.

During January 2020, the net proceeds from the 2030 Senior Notes, along with cash on hand, were used to redeem in full the outstanding indebtedness under the Company's Senior Notes due January 2020 and Senior Notes due March 2020.

All of the senior notes are unsecured obligations of the Company and rank equally with the Company's other senior unsecured obligations. None of the Company's senior notes have a sinking fund requirement.

The Company may redeem its outstanding senior notes prior to scheduled maturity, as a whole or in part, at a redemption price equal to the present value of the remaining scheduled payments of principal and interest, except for certain notes for which the Company also has an option to redeem such instruments at par value on or after dates specified in the indentures governing the notes. For notes with the par value redemption option, if such notes are redeemed prior to the specified dates, the redemption price calculations exclude any interest that would have been due after such dates.

14. LEASES

The Company determines if an arrangement is or contains a lease at contract inception. The Company leases office space, patient service centers, clinical laboratories, warehouses, logistic hubs and equipment primarily through operating leases with a limited number of finance leases. A right-of-use asset, representing the underlying asset during the lease term, and a lease liability, representing the payment obligation arising from the lease, are recognized on the balance sheet at lease commencement based on the present value of the payment obligation. For operating leases, expense is recognized on a straight-line basis over the lease term. For finance leases, interest expense on the lease liability is recognized using the effective interest method and amortization of the right-of-use asset is recognized on a straight-line basis over the shorter of the estimated useful life of the asset or the lease term. Short-term leases with an initial term of 12 months or less are not recorded on the balance sheet; the Company recognizes lease expense for these leases on a straight-line basis over the lease term. For the year ended December 31, 2019, lease expense associated with short-term leases was not material.

The Company primarily uses its collateralized incremental borrowing rate in determining the present value of lease payments as the Company's leases generally do not provide an implicit rate. Such incremental borrowing rates, which take into account interest rates offered to companies that have similar credit ratings as the Company, are determined using a portfolio approach which groups the Company’s leases based on tenor.

The Company has lease agreements with (i) right-of-use asset payments and (ii) non-lease components (i.e. payments related to maintenance fees, utilities, etc,) which have been combined and accounted for as a single lease component.

The Company's leases have remaining terms of less than 1 year to 15 years, some of which include options to extend the leases for up to 15 years. The Company's lease terms may include renewal options that are reasonably certain to be exercised and termination options that are reasonably certain not to be exercised. Certain leases also include options to purchase the leased property.

Certain of the Company's lease agreements include rental payments adjusted periodically for inflation or a market rate which are included in the lease liabilities.

Weighted-average remaining lease term (years):
Operating leases	5
Finance leases	12

Weighted-average discount rate:

The Company's discount rates for its operating leases were primarily determined using the Company's incremental borrowing rate. The Company's weighted-average discount rate for its finance leases principally reflects the implicit interest rate on a lease obligation assumed in a business combination.

15. FINANCIAL INSTRUMENTS

Interest Rate Derivatives – Cash Flow Hedges

From time to time, the Company has entered into various interest rate lock agreements and forward-starting interest rate swap agreements to hedge part of the Company's interest rate exposure associated with the variability in future cash flows attributable to changes in interest rates.

In February 2019, the Company entered into interest rate lock agreements with several financial institutions for a total notional amount of $250 million, which were accounted for as cash flow hedges. These agreements were entered into to hedge a portion of the Company's interest rate exposure associated with variability in future cash flows attributable to changes in the ten-year treasury rates related to the anticipated issuance of debt during 2019. In connection with the issuance of the 2029 Senior Notes, these agreements were settled and the Company paid $1 million. These losses are deferred in stockholders' equity, net of taxes, as a component of accumulated other comprehensive loss, and amortized as an adjustment to interest expense, net over the term of the 2029 Senior Notes.

During the third and fourth quarters of 2019, the Company entered into forward-starting interest rate swap agreements with several financial institutions for a total notional amount of $400 million, which were accounted for as cash flow hedges. The swap agreements were entered into to hedge a portion of the Company's interest rate exposure associated with variability in future cash flows attributable to changes in interest rates over a ten-year period related to the anticipated issuance of debt. In connection with the issuance of the 2030 Senior Notes, these agreements were settled and the Company received $6 million. These gains are deferred in stockholders' equity, net of taxes, as a component of accumulated other comprehensive loss, and amortized as an adjustment to interest expense, net over a ten-year period.

The total net loss, net of taxes, recognized in accumulated other comprehensive loss, related to the Company's cash flow hedges was $4 million and $9 million as of December 31, 2019 and 2018, respectively. The net amount of deferred losses on cash flow hedges that is expected to be reclassified from accumulated other comprehensive loss into interest expense, net within the next twelve months is $2 million.

Interest Rate Derivatives – Fair Value Hedges

The Company maintains various fixed-to-variable interest rate swap agreements to convert a portion of the Company's long-term debt into variable interest rate debt. A summary of the notional amounts of these interest rate swap agreements as of December 31, 2019 and 2018 was as follows:

Share Repurchase Program

In November 2019, the Company's Board of Directors authorized the Company to repurchase an additional $1 billion of the Company's common stock. As of December 31, 2019, $1.2 billion remained available under the Company’s share repurchase authorization. The share repurchase authorization has no set expiration or termination date.

Share Repurchases

For the year ended December 31, 2019, the Company repurchased 3.5 million shares of its common stock for $350 million.

For the year ended December 31, 2018, the Company repurchased 3.4 million shares of its common stock for $325 million, which included an accrual of $3 million recorded in accounts payable and accrued expenses in the consolidated balance sheet for share repurchases not settled until after December 31, 2018.

For the year ended December 31, 2017, the Company repurchased 4.6 million shares of its common stock for $465 million.

Shares Reissued from Treasury Stock

For the years ended December 31, 2019, 2018 and 2017 the Company reissued 2 million shares, 3 million shares and 2 million shares, respectively, from treasury stock for shares issued under the Employee Stock Purchase Plan ("ESPP") and stock option plans.

Redeemable Noncontrolling Interest

In connection with the sale of an 18.9% noncontrolling interest in a subsidiary to UMass on July 1, 2015, the Company granted UMass the right to require the Company to purchase all of its interest in the subsidiary at fair value commencing July 1, 2020. The subsidiary performs diagnostic information services in a defined territory within the state of Massachusetts. Since the redemption of the noncontrolling interest is outside of the Company's control, it has been presented outside of stockholders' equity at the greater of its carrying amount or its fair value. The Company records changes in the fair value of the noncontrolling interest immediately as they occur. As of December 31, 2019 and 2018, the redeemable noncontrolling interest was $76 million and $77 million, respectively, and was presented at its fair value.

17. STOCK OWNERSHIP AND COMPENSATION PLANS

Employee and Non-employee Directors Stock Ownership Programs

In 2005, the Company established the ELTIP to replace the Company's prior plan. The ELTIP provides for three types of awards: (a) stock options, (b) stock appreciation rights and (c) stock awards. The ELTIP provides for the grant to eligible employees of either non-qualified or incentive stock options, or both, to purchase shares of Company common stock at an exercise price no less than the fair market value of the Company's common stock on the date of grant. Grants of stock appreciation rights allow eligible employees to receive a payment based on the appreciation of Company common stock in cash, shares of Company common stock or a combination thereof. The stock appreciation rights are granted at an exercise price no less than the fair market value of the Company's common stock on the date of grant. Stock options and stock appreciation rights granted under the ELTIP expire on the date designated by the Board of Directors but in no event more than ten years from date of grant. No stock appreciation rights have been granted under the ELTIP. The stock options and shares are subject to forfeiture if employment terminates prior to the end of the vesting period prescribed by the Board of Directors. For all award types, the vesting period is generally over three years from the date of grant. For performance share unit awards, the actual amount of shares earned is based on the achievement of the performance goals specified in the awards. The maximum number of shares of Company common stock that may be optioned or granted under the ELTIP is approximately 79 million shares.

In 2005, the Company established the DLTIP to replace the Company's prior plan. The DLTIP provides for the grant to non-employee directors of non-qualified stock options to purchase shares of Company common stock at an exercise price no less than the fair market value of the Company's common stock on the date of grant. The DLTIP also permits awards of

F- 39

Table of Contents

QUEST DIAGNOSTICS INCORPORATED AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – CONTINUED

(in millions unless otherwise indicated)

restricted stock and restricted stock units to non-employee directors. Stock options granted under the DLTIP expire on the date designated by the Board of Directors but in no event more than ten years from date of grant. For all award types, the vesting period is generally over three years from the date of grant, regardless of whether the award recipient remains a director of the Company. The maximum number of shares that may be issued under the DLTIP is 2.4 million shares. For the years ended December 31, 2019, 2018 and 2017, grants under the DLTIP totaled 14 thousand shares, 15 thousand shares and 13 thousand shares, respectively.

The Company's practice has been to issue shares related to its stock-based compensation program from shares of its common stock held in treasury or by issuing new shares of its common stock. See Note 16 for further information regarding the Company's share repurchase program.

The fair value of each stock option award granted was estimated on the date of grant using a Black-Scholes option-valuation model. The expected volatility under the Black-Scholes option-valuation model was based on historical volatilities of the Company's common stock. The dividend yield was based on the approved annual dividend rate in effect and current market price of the underlying common stock at the time of grant. The risk-free interest rate was based on the U.S. Treasury yield curve in effect at the time of grant for bonds with maturities consistent with the expected holding period of the related award. The expected holding period was estimated using the historical stock option exercise behavior of employees.

The weighted average assumptions used in valuing stock options granted in the periods presented were:



	2019	2018	2017

Fair value at grant date	$14.30	$18.14	$15.98
Expected volatility	20.4%	19.1%	19.8%
Dividend yield	2.4%	1.9%	1.9%
Risk-free interest rate	2.5%	2.8%	2.1%
Expected holding period, in years	5.2	5.3	5.2

The fair value of restricted stock awards, restricted stock units and performance share units is the average market price of the Company's common stock at the date of grant.

The following summarizes the activity relative to stock option awards for 2019:



	Shares		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value

Options outstanding, beginning of year	8.4		$	77.35
Options granted	1.8		87.16
Options exercised	(1.8	)	65.03
Options forfeited and canceled	(0.4	)	94.68
Options outstanding, end of year	8.0		$	81.67	6.7	$	202

Exercisable, end of year	5.0		$	74.72	5.5	$	161

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the Company's closing common stock price on the last trading day of 2019 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, 2019. This amount changes based on the fair market value of the Company's common stock. Total intrinsic value of options exercised in 2019, 2018 and 2017 was $62 million, $67 million and $94 million, respectively.

As of December 31, 2019, there was $11 million of unrecognized stock-based compensation cost related to nonvested stock options which is expected to be recognized over a weighted average period of 1.7 years.

As of December 31, 2019, there was $20 million of unrecognized stock-based compensation cost related to nonvested stock awards, which is expected to be recognized over a weighted average period of 1.7 years. Total fair value of shares vested was $40 million, $54 million and $58 million for the years ended December 31, 2019, 2018 and 2017, respectively. The amount of unrecognized stock-based compensation cost is subject to change based on changes, if any, to management's best estimates of the achievement of the performance goals specified in such awards and the resulting number of shares that will be earned at the end of the performance periods.

For the years ended December 31, 2019, 2018 and 2017, stock-based compensation expense totaled $56 million, $61 million and $79 million, respectively. Income tax benefits recognized in the consolidated statements of operations related to stock-based compensation expense totaled $27 million, $33 million and $67 million for the years ended December 31, 2019, 2018 and 2017, respectively, which includes excess tax benefits associated with stock-based compensation arrangements of $13 million, $18 million and $37 million for the years ended December 31, 2019, 2018 and 2017, respectively.

Employee Stock Purchase Plan

Under the Company's ESPP, substantially all employees can elect to have up to 10% of their annual wages withheld to purchase Quest Diagnostics common stock. The purchase price of the stock is 95% of the market price of the Company's common stock on the last business day of each calendar month. Under the ESPP, the maximum number of shares of Quest Diagnostics common stock which may be purchased by eligible employees is 9 million. Approximately 269 thousand, 326 thousand and 278 thousand shares of common stock were purchased by eligible employees in 2019, 2018 and 2017, respectively.

Defined Contribution Plans

The Company maintains qualified defined contribution plans covering substantially all of its employees. The maximum Company matching contribution is 5% of eligible employee compensation. The Company's expense for contributions to its defined contribution plans aggregated $84 million, $78 million and $76 million for 2019, 2018 and 2017, respectively.

Supplemental Deferred Compensation Plans

The Company has a supplemental deferred compensation plan that is an unfunded, non-qualified plan that provides for certain management and highly compensated employees to defer up to 50% of their salary in excess of their defined contribution plan limits and for certain eligible employees, up to 95% of their variable incentive compensation. The maximum Company matching contribution is 5% of eligible employee compensation. The compensation deferred under this plan, together with Company matching amounts, are credited with earnings or losses measured by the mirrored rate of return on investments elected by plan participants. Each plan participant is fully vested in all deferred compensation, Company match and earnings credited to their account. The amounts accrued under the Company's deferred compensation plans were $59 million and $53 million as of December 31, 2019 and 2018, respectively. Although the Company is currently contributing all participant deferrals and matching amounts to trusts, the funds in these trusts, totaling $59 million and $53 million as of December 31, 2019 and 2018, respectively, are general assets of the Company and are subject to any claims of the Company's creditors.

The Company also offers certain employees the opportunity to participate in a non-qualified deferred compensation program. Eligible participants are allowed to defer up to $20 thousand of eligible compensation per year. The Company matches employee contributions equal to 25%, up to a maximum of $5 thousand per plan year. A participant's deferrals, together with Company matching credits, are “invested” at the direction of the employee in a hypothetical portfolio of investments which are tracked by an administrator. Each participant is fully vested in their deferred compensation and vests in Company matching contributions over a period of four years at 25% per year. This plan was amended effective January 1, 2018 so that future deferrals under the plan may only be made by participants who made deferrals under the plan in 2017. The amounts accrued under this plan were $51 million and $43 million as of December 31, 2019 and 2018, respectively. The Company purchases life insurance policies, with the Company named as beneficiary of the policies, for the purpose of funding the program's liability. The cash surrender value of such life insurance policies was $43 million and $34 million as of December 31, 2019 and 2018, respectively.

For each of the years ended December 31, 2019, 2018 and 2017, the Company's expense for matching contributions to these plans was not material.

18. COMMITMENTS AND CONTINGENCIES

Letters of Credit and Contractual Obligations

The Company can issue letters of credit under its Secured Receivables Credit Facility and Senior Unsecured Revolving Credit Facility (see Note 13). In support of its risk management program, to ensure the Company’s performance or payment to third parties, $71 million in letters of credit under the Secured Receivables Credit Facility were outstanding as of December 31, 2019. The letters of credit primarily represent collateral for current and future automobile liability and workers’ compensation loss payments.

The Company has certain noncancelable commitments, primarily under take-or-pay arrangements, to purchase products or services from various suppliers, mainly for consulting and other service agreements, and standing orders to purchase reagents and other laboratory supplies. As of December 31, 2019, the approximate total future purchase commitments are $210 million, of which $83 million are expected to be incurred in 2020, $91 million are expected to be incurred in 2021 through 2022 and the balance thereafter.

Billing and Collection Agreement

In September 2016, the Company entered into a ten-year agreement with a third party to outsource its billing and related operations for the majority of the Company’s revenues. Services under the agreement commenced during the fourth quarter of 2016. The agreement includes an annual fee, which is subject to adjustment based on certain changes in the Company's requisition volume and the achievement of various performance metrics.

Contingent Lease Obligations

The Company remains subject to contingent obligations under certain real estate leases, including real estate leases that were entered into by certain predecessor companies of a subsidiary prior to the Company's acquisition of the subsidiary. While over the course of many years, the title to certain properties and interest in the subject leases have been transferred to third parties and the subject leases have been amended several times by such third parties, the lessors have not formally released the subsidiary predecessor companies from their original obligations under the leases and therefore remain contingently liable in the event of default. The remaining terms of the lease obligations and the Company's corresponding indemnifications range up to 28 years. The lease payments under certain leases are subject to market value adjustments and contingent rental payments and therefore, the total contingent obligations under the leases cannot be precisely determined but are likely to total several hundred million dollars. A claim against the Company would be made only upon the current lessee's default and, in certain cases, after a series of claims and corresponding defaults by third parties that precede the Company in the order of liability. The Company also has certain indemnification rights from other parties to recover losses in the event of default on the lease obligations. The Company believes that the likelihood of its performance under these contingent obligations is remote and no liability has been recorded for any potential payments under the contingent lease obligations.

AMCA Data Security Incident

On June 3, 2019, the Company reported that Retrieval-Masters Creditors Bureau, Inc./American Medical Collection Agency (“AMCA”) had informed the Company and Optum360 LLC that an unauthorized user had access to AMCA’s system between August 1, 2018 and March 30, 2019 (the “AMCA Data Security Incident”). Optum360 provides revenue management services to the Company, and AMCA provided debt collection services to Optum360. AMCA first informed the Company of the AMCA Data Security Incident on May 14, 2019. AMCA’s affected system included financial information (e.g., credit card numbers and bank account information), medical information and other personal information (e.g., social security numbers). Test results were not included. Neither Optum360’s nor the Company’s systems or databases were involved in the incident. AMCA also informed the Company that information pertaining to other laboratories’ customers was also affected. Following announcement of the AMCA Data Security Incident, AMCA sought protection under the U.S. bankruptcy laws.

Following the AMCA Data Security Incident, 39 lawsuits were filed against the Company related to the incident; two of those suits subsequently have been dismissed. All but one of the remaining lawsuits are putative class actions in which the plaintiffs purport to represent various classes of consumers. In the pending cases, (most of which also name other defendants), plaintiffs assert a variety of common law and statutory claims in connection with the AMCA Data Security Incident. The U.S. Judicial Panel on Multidistrict Litigation transferred the cases to, and consolidated them for pre-trial proceedings in, the U.S. District Court for New Jersey. On November 15, 2019, the plaintiffs in the multidistrict proceeding filed a consolidated putative class action complaint against the Company and Optum360 that named additional individuals as plaintiffs and that asserted a variety of common law and statutory claims in connection with the AMCA Data Security Incident. On January 22, 2020, the Company moved to dismiss the consolidated complaint.

In addition, certain federal and state governmental authorities are investigating, or otherwise seeking information and/or documents from the Company related to the AMCA Data Security Incident and related matters, including the Office for Civil Rights of the U.S. Department of Health and Human Services, Attorneys General offices from numerous states and the District of Columbia, and certain U.S. senators.

The Company has insurance coverage rights in place for certain potential costs and liabilities related to the AMCA Data Security Incident; this insurance coverage is limited in amount and subject to a deductible. While management believes it is reasonably possible that the Company may incur losses associated with these proceedings and investigations, it is not possible to estimate the amount of loss or range of loss, if any, that might result from adverse judgments, settlements, fines,

F- 43

(in millions unless otherwise indicated)

penalties, or other resolution of these proceedings and investigations based on the stage of these proceedings and investigations, the absence of specific allegations as to alleged damages, the uncertainty as to the certification of a class or classes and the size of any certified class, if applicable, and/or the lack of resolution of significant factual and legal issues.

Other Legal Matters

In the normal course of business, the Company has been named, from time to time, as a defendant in various legal actions, including arbitrations, class actions and other litigation, arising in connection with the Company's activities as a provider of diagnostic testing, information and services. These actions could involve claims for substantial compensatory and/or punitive damages or claims for indeterminate amounts of damages, and could have an adverse impact on the Company's client base and reputation.

The Company is also involved, from time to time, in other reviews, investigations and proceedings by governmental agencies regarding the Company's business which may result in adverse judgments, settlements, fines, penalties, injunctions or other relief.

The federal or state governments may bring claims based on the Company's current practices, which it believes are lawful. In addition, certain federal and state statutes, including the qui tam provisions of the federal False Claims Act, allow private individuals to bring lawsuits against healthcare companies on behalf of government or private payers. The Company is aware of lawsuits, and from time to time has received subpoenas, related to billing practices based on the qui tam provisions of the Civil False Claims Act or other federal and state statutes, regulations or other laws. The Company understands that there may be other pending qui tam claims brought by former employees or other "whistle blowers" as to which the Company cannot determine the extent of any potential liability.

Management cannot predict the outcome of such matters. Although management does not anticipate that the ultimate outcome of such matters will have a material adverse effect on the Company's financial condition, given the high degree of judgment involved in establishing loss estimates related to these types of matters, the outcome of such matters may be material to the Company's results of operations or cash flows in the period in which the impact of such matters is determined or paid.

These matters are in different stages. Some of these matters are in their early stages. Matters may involve responding to and cooperating with various government investigations and related subpoenas. As of December 31, 2019, the Company does not believe that material losses related to legal matters are probable.

Reserves for legal matters totaled $1 million as of both December 31, 2019 and December 31, 2018.

Reserves for General and Professional Liability Claims

As a general matter, providers of clinical testing services may be subject to lawsuits alleging negligence or other similar legal claims. These suits could involve claims for substantial damages. Any professional liability litigation could also have an adverse impact on the Company's client base and reputation. The Company maintains various liability insurance coverages for, among other things, claims that could result from providing, or failing to provide, clinical testing services, including inaccurate testing results, and other exposures. The Company's insurance coverage limits its maximum exposure on individual claims; however, the Company is essentially self-insured for a significant portion of these claims. Reserves for such matters, including those associated with both asserted and incurred but not reported claims, are established on an undiscounted basis by considering actuarially determined losses based upon the Company's historical and projected loss experience. Such reserves totaled $132 million and $125 million as of December 31, 2019 and December 31, 2018, respectively. Management believes that established reserves and present insurance coverage are sufficient to cover currently estimated exposures.

Quarterly Operating Results (unaudited)

(in millions, except per share data)

(a)

During the third quarter of 2006, the Company completed the wind down of Nichols Institute Diagnostics ("NID"), a test kit manufacturing subsidiary. As a result, NID was classified as discontinued operations for all periods presented (see Note 21 to the audited consolidated financial statements). The process for estimating revenues and the ultimate collection of accounts receivable involves significant judgment and estimation. The Company follows a standard process, which considers historical denial and collection experience and other factors, to estimate contractual allowances and implicit price concessions, recording adjustments in the current period as changes in estimates. Based on this process, during the fourth quarter of 2018, the Company increased its reserves for revenues and accounts receivable by approximately $35 million (see Note 3 to the consolidated financial statements).

(b)

Included pre-tax amortization expense of $29 million ($24 million in amortization of intangible assets and $5 million in equity in earnings of equity method investees, net of taxes); pre-tax charges of $22 million, primarily associated with system conversions and integration incurred in connection with further restructuring and integrating the Company ($11 million in cost of services and $11 million in selling, general and administrative expenses); a net pre-tax gain of $8 million, primarily due to a gain associated with an insurance claim for hurricane related losses partially offset by non-cash asset impairment charges ($1 million charge in selling, general and administrative expenses offset by a $9 million gain in other operating (income) expense, net); and excess tax benefits associated with stock-based compensation arrangements of $3 million recorded in income tax expense.

(c)

Included pre-tax amortization expense of $30 million ($25 million in amortization of intangible assets and $5 million in equity in earnings of equity method investees, net of taxes); pre-tax charges of $26 million, primarily associated with system conversions and integration incurred in connection with further restructuring and integrating the Company ($11 million in cost of services and $15 million in selling, general and administrative expenses); a net pretax gain of $6 million in other operating (income) expense, net, primarily due to a gain associated with the decrease in the fair value of the contingent consideration accrual associated with a previous acquisition; and excess tax benefits associated with stock-based compensation arrangements of $5 million recorded in income tax expense. Income from discontinued operations, net of taxes includes discrete tax benefits of $20 million associated with the favorable resolution of certain tax contingencies related to NID.

(d)
