2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    Basis of Presentation
    
    The interim unaudited consolidated financial statements reflect all adjustments which in the opinion of management are necessary for a fair statement of results of operations, comprehensive income, financial condition, cash flows and stockholders' equity for the periods presented. Except as otherwise disclosed, all such adjustments are of a normal recurring nature. Operating results for the interim periods are not necessarily indicative of the results that may be expected for the full year. These interim unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company’s 2019 Annual Report on Form 10-K. The year-end balance sheet data was derived from the audited consolidated financial statements as of December 31, 2019, but does not include all the disclosures required by accounting principles generally accepted in the United States (“GAAP”).

    The accounting policies of the Company are the same as those set forth in Note 2 to the audited consolidated financial statements contained in the Company’s 2019 Annual Report on Form 10-K except for the impact of the adoption of new accounting standards discussed under New Accounting Pronouncements.

    A novel strain of coronavirus (“COVID-19”) continues to spread and severely impact the economy of the United States and other countries around the world. Federal,Since March 2020, federal, state and local governmental policies and initiatives designed to reduce the transmission of COVID-19 have resulted in, among other things, a significant reduction in physician office visits, the cancellation of elective medical procedures, customers closing or severely curtailing their operations (voluntarily or in response to government orders), and the adoption of work-from-home policies, all of which have had, and the Company believes will continue to have, an impact on the Company’s consolidated results of operations, financial position, and cash flows. Additionally, beginning during the second quarter of 2020, the Company experienced growing demand for COVID-19 molecular and antibody testing services and has expanded its capacity in order to satisfy such demand. As a result, operating results for the three and sixnine months ended JuneSeptember 30, 2020 may not be indicative of the results that may be expected for the full year.

    The preparation of financial statements in conformity with 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.

    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 and its Amended and Restated Non-Employee Director Long-Term Incentive Plan. 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.

    New Accounting Pronouncements
    
    Adoption of New Accounting Standards    
    
    On January 1, 2020, the Company adopted a new accounting standard issued by the Financial Accounting Standards Board ("FASB") which 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. The adoption of this standard, which the Company elected to do on a prospective basis, did not have a material impact on the Company's consolidated results of operations, financial position or cash flows.

    On January 1, 2020, the Company adopted a new accounting standard issued by the FASB 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 requires entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. The adoption of this new standard, which was done using a modified retrospective transition approach, did not have a material impact on the Company's consolidated results of operations, financial position or cash flows. See Note 15 for further details on the Company's allowance for credit losses policy.

    New Accounting Standards to be Adopted

    In March 2020, the FASB issued a new accounting standard which provides temporary optional guidance to ease the potential burden in accounting for reference rate reform due to the risk of cessation of the London Interbank Offered Rate ("LIBOR"). The amendments apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The pronouncement is effective immediately and can be applied through December 31, 2022. The adoption of this standard is not expected to have a material impact on the Company’s consolidated results of operations, financial position or cash flows.

5.     BUSINESS ACQUISITIONS

    On January 21, 2020, the Company completed its acquisition of Blueprint Genetics Oy ("Blueprint Genetics"), in an all cash transaction for $108 million, net of $3 million cash acquired. Blueprint Genetics is a leading specialty genetic testing company with deep expertise in gene variant interpretation based on next generation sequencing and proprietary bioinformatics. Through the acquisition, the Company acquired all of Blueprint Genetics' operations. Based on the preliminary purchase price allocation, which may be revised as additional information becomes available during the measurement period, the assets acquired and liabilities assumed primarily consist of $77 million of goodwill (0ne of which is tax-deductible), $43 million of intangible assets, an $11 million deferred tax liability, and $2 million of property, plant and equipment and working capital. The intangible assets primarily consist of technology and customer-related assets which are being amortized over a useful life of 10 years and 15 years, respectively.

    On April 6, 2020, the Company completed its acquisition of select assets which constitute substantially all of the operations of Memorial Hermann Diagnostic Laboratories, the outreach laboratory division of Memorial Hermann Health System ("Memorial Hermann"), in an all cash transaction for $120 million. Memorial Hermann is a not-for-profit health system in Southeast Texas. Based on the preliminary purchase price allocation, which may be revised as additional information becomes available during the measurement period, the assets acquired primarily consist of $27 million of customer-related intangible assets and $93 million of tax-deductible goodwill. The intangible assets are being amortized over a useful life of 15 years.

    On August 1, 2020, the Company completed its acquisition of the remaining 56% interest in Mid America Clinical Laboratories, LLC ("MACL") from its joint venture partners in an all cash transaction for $93 million, net of $18 million cash acquired. The final consideration is subject to post closing adjustments related to working capital. MACL is the largest independent clinical laboratory provider in Indiana. Prior to the acquisition, the Company accounted for its 44% interest in MACL as an equity method investment, which was remeasured to its fair value of $87 million on the acquisition date, resulting in a gain of $70 million that was recognized in other income, net in the consolidated statements of operations. The fair value of the previously held equity interest was determined using a discounted cash flow analysis that takes into account, among other items, MACL's expected future cash flows, long-term growth rate (1.5%), and a discount rate commensurate with economic risk (7.5%). Based on the preliminary purchase price allocation, which may be revised as additional information becomes available during the measurement period, the assets acquired and liabilities assumed consist of $84 million of goodwill (of which $47 million is tax-deductible), $74 million of intangible assets, $11 million of working capital and $11 million of property, plant and equipment. The intangible assets consist of customer-related assets which are being amortized over a useful life of 15 years. As a result of the acquisition, MACL became a wholly owned subsidiary of the Company.

The acquisitions were accounted for under the acquisition method of accounting. As such, the assets acquired and liabilities assumed were recorded based on their estimated fair values as of the closing date. Supplemental pro forma combined financial information has not been presented as the impact of the acquisitions is not material to the Company's consolidated financial statements. The goodwill recorded primarily includes the expected synergies resulting from combining the operations of the acquired entities with those of the Company and the value associated with an assembled workforce and other intangible assets that do not qualify for separate recognition. All of the goodwill acquired in connection with these acquisitions has been allocated to the Company's DIS business. For further details regarding business segment information, see Note 13.

        On June 22, 2020, the Company entered into definitive agreements with its joint venture partners to acquire their 56% interest in Mid America Clinical Laboratories, LLC ("MACL"), which the Company currently accounts for as an equity method investment. Closing of the transaction, which is expected to occur during the third quarter of 2020, remains subject to customary closing conditions. MACL is the largest independent clinical laboratory provider in Indiana. Upon close of the transaction, MACL will become a wholly owned subsidiary of the Company and the Company expects to remeasure its previously held equity interest in MACL to its acquisition date fair value and recognize a gain in its consolidated statements of operations.

    For details regarding the Company's 2019 acquisitions, see Note 6 to the audited consolidated financial statements in the Company's 2019 Annual Report on Form 10-K.

    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

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. 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, which were terminated during April 2020 (see Note 9), were classified within Level 2 of the fair value hierarchy and were based on 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 obligationsliabilities that are to be paid based on the achievement of certain testing volume or revenue benchmarks. As of JuneSeptember 30, 2020, the fair value of these contingent consideration liabilities totaled $6 million.was immaterial. 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 as of September 30, 2020 is as follows:

        The $1 million net gain included in earnings associated with the change in the fair value of contingent consideration for the six months ended June 30, 2020 is reported in other operating income, 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 JuneSeptember 30, 2020, 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 both JuneSeptember 30, 2020 and December 31, 2019, the fair value of the Company’s debt was estimated at $5.2 billion and $5.1 billion.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.

of credit facility, which mature in October 2021.the borrowing capacity at $600 million. See Note 18 for further details. The senior unsecured revolving credit facility matures in March 2023. For further details regarding the credit facilities, see Note 13 to the audited consolidated financial statements in the Company's 2019 Annual Report on Form 10-K.

    The secured receivables credit facility is subject to customary affirmative and negative covenants, and certain financial covenants with respect to the receivables that comprise the borrowing base and secure the borrowings under the facility. The Company's senior unsecured revolving credit facility is also subject to certain financial covenants and limitations on indebtedness. On April 30, 2020, the Company entered into an amendment to the senior unsecured revolving credit facility in order to provide for increased flexibility. Pursuant to the amendment, the leverage ratio covenant (as defined in the senior unsecured revolving credit facility) was increased from the second quarter of 2020 as follows:
As of:Applicable Covenant:
June 30, 2020no more than 5 times EBITDA
September 30, 2020no more than 5.5 times EBITDA
December 31, 2020no more than 6.5 times EBITDA
March 31, 2021no more than 6.25 times EBITDA
June 30, 2021no more than 4.5 times EBITDA

    Thereafter, the leverage ratio covenant reverts to no more than 3.5 times EBITDA. During the period that the increased covenant applies, which period may be terminated early by the Company provided that it is in compliance with the historical 3.5 times EBITDA leverage ratio, the amended credit agreement contains certain additional limitations and restrictions including, but not limited to, repurchases of the Company's common stock, the amount of funds that can be used on business acquisitions, the incurrence of secured indebtedness and the payment of dividends. As of JuneSeptember 30, 2020, the Company was in compliance with all such applicable financial covenants. Interest on the amended senior unsecured revolving credit facility is subject to a pricing schedule that can fluctuate based on changes in the Company's credit ratings and its leverage ratio.

    During the sixnine months ended JuneSeptember 30, 2020, the Company borrowed $100 million under its secured receivables credit facility and $100 million under its senior unsecured revolving credit facility, both of which were repaid prior to JuneSeptember 30, 2020.

9.    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.

    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 enters 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.

    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.

    During March 2020, the Company entered into a forward-starting interest rate swap agreement with a financial institution for a total notional amount of $25 million. Additionally, during May 2020, the Company entered into interest rate lock agreements with several financial institutions for a total notional amount of $275 million. The forward-starting interest rate swap agreement and the interest rate lock agreements were entered into in order 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 an anticipated issuance of debt and were accounted for as cash flow hedges. In connection with the issuance of the 2031 Senior Notes (see Note 8), these agreements were settled and the Company received net proceeds of $1 million. The net gain is deferred in stockholders' equity, net of taxes, as a component of accumulated other comprehensive loss, and is being 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 $1 million and $4 million as of both JuneSeptember 30, 2020 and December 31, 2019.2019, 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 $1 million.

    Interest Rate Derivatives – Fair Value Hedges

    As of December 31, 2019, the Company had various fixed-to-variable interest rate swap agreements outstanding with an aggregate notional amount of $1.2 billion, which were entered into in order to convert a portion of the Company's long-term debt into variable interest rate debt. In April 2020, the Company terminated these existing fixed-to-variable interest rate swap agreements and received proceeds of $40 million. Such amount iswas reflected as a basis adjustment to the hedged debt instruments and is being amortized as a reduction of interest expense, net over their remaining terms.

    As of JuneSeptember 30, 2020 and December 31, 2019, the following amounts were recorded on the consolidated balance sheets related to cumulative basis adjustments for fair value hedges included in the carrying amount of long-term debt:

    In March 2020, in response to the COVID-19 pandemic, the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") was signed into law. The CARES Act provides numerous tax provisions and other stimulus measures, including temporary changes regarding the prior and future utilization of net operating losses, temporary changes to the prior and future limitations on interest deductions, temporary suspension of certain payment requirements for the employer portion of social security taxes, technical corrections from prior tax legislation for tax depreciation of certain qualified improvement property, and the creation of certain payroll tax credits associated with the retention of employees. The CARES Act also includes a number of benefits that are applicable to the Company and other healthcare providers including, but not limited to, the appropriation of $100 billion to health care providers for related expenses or lost revenues that are attributable to the COVID-19 pandemic.

    In April 2020 and August 2020, the Company received approximately $65 million from the initial trancheand $73 million, respectively, of funds from the government that were distributed to healthcare providers for related expenses or lost revenues that are attributable to the COVID-19 pandemic under the CARES Act.

During the three months ended June 30, 2020, based on the terms and conditions that were in effect at such time, the Company concluded that it had satisfied such terms and conditions for additionalthe $65 million of funds that were received in April 2020 and, therefore, the Company recognized such amount in other operating expense (income), net during the second quarter. During the three months ended September 30, 2020, the Company reversed the $65 million of funds that had previously been recognized in other operating expense (income), net. As of September 30, 2020, no amounts are recorded in the Company's year-to-date consolidated statement of operations and the entire $138 million of funds that the Company intends to bereturn are recorded in accounts payable and accrued expenses on the Company’s consolidated balance sheet.

As of June 30, 2020, the Company had not yet received approval of its application from HHS for the additional funds requested. As such, the Company's consolidated financial statements as of and for the period ended June 30, 2020 exclude any additional funds that may be distributed by the government for related expenses or lost revenues that are attributable to the COVID-19 pandemic under the CARES Act.


12.     COMMITMENTS AND CONTINGENCIES

    Letters of Credit

    The Company can issue letters of credit totaling $100 million under its secured receivables credit facility and $150 million under its senior unsecured revolving credit facility. For further discussion regarding the Company's secured receivables credit facility and senior unsecured revolving credit facility, see Note 13 to the audited consolidated financial statements in the Company's 2019 Annual Report on Form 10-K and Note 8 to the interim unaudited consolidated financial statements.    
    
    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 JuneSeptember 30, 2020. The letters of credit primarily represent collateral for current and future automobile liability and workers’ compensation loss payments.

    Contingent Lease Obligations
    
    The Company remains subject to contingent obligations under certain real estate leases, including leases that were entered into by certain predecessor companies of a subsidiary prior to the Company's acquisition of the subsidiary. No liability has been recorded for any of these potential contingent obligations. For further details, see Note 18 to the audited consolidated financial statements in the Company’s 2019 Annual Report on Form 10-K.

    Certain Legal Matters

    The Company may incur losses associated with these proceedings and investigations, but it is not possible to estimate the amount of loss or range of loss, if any, that might result from adverse judgments, settlements, fines, 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. The Company has insurance coverage rights in place (limited in amount; subject to deductible) for certain potential costs and liabilities related to these proceedings and investigations.

401(k) Plan Lawsuit

    In June 2020, a putative class action lawsuit, House Johnson v. Quest Diagnostics Incorporated, et. al, was filed in the U.S. District Court for New Jersey against the Company and other defendants with respect to the Company’s 401(k) plan. The complaint alleges, among other things, that the fiduciaries of the 401(k) plan breached their duties by failing to disclose the expenses and risks of plan investment options, allowing unreasonable administration expenses to be charged to plan participants, and selecting and retaining high cost and poor performing investments. In July 2020, a putative class action lawsuit, Rice, et. al v. Quest Diagnostics Incorporated, et. al, was filed in the U.S. District Court for New Jersey. The plaintiffs in the Rice case named the same defendants as those named in the House Johnson case and alleged substantially similar claims to those made in the House Johnson matter. In October 2020, the court consolidated the two lawsuits and plaintiffs filed a consolidated amended complaint. The Company plans to vigorously defend this matter.

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, numerousNumerous putative class action lawsuits were filed against the Company related to the incident.AMCA Data Security Incident. The U.S. Judicial Panel on Multidistrict Litigation transferred the cases still pending to, and consolidated them for pre-trial proceedings in, the U.S. District Court for New Jersey. In November 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. In January 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.

    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 consolidated 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 JuneSeptember 30, 2020, the Company does not believe that material losses related to legal matters are probable.

        Reserves for legal matters totaled $2 million and $1 million as of June 30, 2020 and December 31, 2019, respectively.

    Reserves for legal matters totaled $1 million as of both September 30, 2020 and December 31, 2019, respectively.

    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 $136$134 million and $132 million as of JuneSeptember 30, 2020 and December 31, 2019, respectively. Management believes that established reserves and present insurance coverage are sufficient to cover currently estimated exposures.

15.    REVENUE RECOGNITION AND ALLOWANCE FOR CREDIT LOSSES

    DIS

    Net revenues in the Company’s DIS business accounted for over 95% of the Company’s total net revenues for the three and sixnine months ended JuneSeptember 30, 2020 and 2019 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 obligations and recognizes revenues primarily 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. The portfolios determined using the portfolio approach consist of the following groups of customers: healthcare insurers, government payers (Medicare and Medicaid programs), client payers and patients.

    DS

    The Company’s DS businesses primarily satisfy their performance obligations and recognize revenues when delivery has occurred or services have been rendered.

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

    Allowance for Credit Losses Policy

    When estimating its allowance for credit losses, the Company pools its trade receivables based on the following customer types: healthcare insurers, government payers, client payers and patients. 

    For the healthcare insurers and government payers, collection of the Company’s net revenues is normally a function of providing the complete and correct billing information within the various filing deadlines, and provided that the Company has billed the payers accurately with complete information prior to the established filing deadline, there has historically been little to no collection risk. 

    Client payers primarily include physicians, hospitals, IDNs, ACOs, 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. 

    With respect to patients, implicit price concessions, which represent differences between amounts billed and the estimated consideration the Company expects to receive from patients, are recognized as a reduction of revenue.  Estimates of implicit price concessions consider historical collection experience (including the period the receivables have been outstanding) and other factors including current market conditions.

    The Company principally estimates the allowance for credit losses by pool based on historical collection experience, the current credit worthiness of the customers, current economic conditions, expectations of future economic conditions and the period that the receivables have been outstanding.  To the extent that any individual payers are identified that have deteriorated in credit quality, the Company removes the customers from their respective pools and establishes allowances based on the individual risk characteristics of such customers.

    Although the Company believes that its estimates for contractual allowances and patient price concessions as well as its allowance for credit losses are appropriate, it is possible that the Company will experience an adverse impact on cash collections as a result of the impact of the COVID-19 pandemic.

16.    TAXES ON INCOME

    For the three months ended JuneSeptember 30, 2020 and 2019, the effective income tax rate was 25.5%23.7% and 23.6%22.9%, respectively. The effective income tax rate for the three months ended JuneSeptember 30, 2020, and 2019 benefited from $4a lower effective income tax rate associated with a $70 million gain recognized as a result of the remeasurement of the Company's previously held equity interest in MACL to fair value (see Note 5); and $5$3 million respectively, of excess tax benefits associated with stock-based compensation arrangements. The effective income tax rate for the three months ended September 30, 2019 benefited from a $6 million income tax benefit due to the release of a valuation allowance associated with net operating loss carryforwards; and $3 million of excess tax benefits associated with stock-based compensation arrangements.

For the sixnine months ended JuneSeptember 30, 2020 and 2019, the effective income tax rate was 24.4%23.9% and 23.6%23.4%, respectively. The effective income tax rate for the sixnine months ended JuneSeptember 30, 2020, and 2019 benefited from $12a lower effective income tax rate associated with a $70 million gain recognized as a result of the remeasurement of the Company's previously held equity interest in MACL to fair value (see Note 5); and $8$15 million respectively, of excess tax benefits associated with stock-based compensation arrangements. The effective income tax rate for the nine months ended September 30, 2019 benefited from $11 million of excess tax benefits associated with stock-based compensation arrangements; and a $10 million income tax benefit due to the release of valuation allowances associated with net operating loss carryforwards.

    The effective income tax rate associated with the $70 million gain recognized as a result of the remeasurement of the Company's previously held equity interest in MACL to fair value was 11.8% due to a permanent difference in the financial reporting and tax basis of goodwill.

For the three and sixnine months ended JuneSeptember 30, 2020, the Company utilized the most likely estimate of its annual income before taxes to determine the annual effective income tax rate for 2020. As a result of uncertainty associated with the impact of the COVID-19 pandemic, it is possible that the Company will experience variability in the annual projections and, as a result, the annual effective income tax rate. The Company will update the annual effective income tax rate each quarter during 2020 for changes in the latest projections for the Company.

17.    DISCONTINUED OPERATIONS

    During the third quarter of 2006, the Company completed the wind down of Nichols Institute Diagnostics ("NID"), a test kit manufacturing subsidiary, which was reported as a discontinued operation for the three and sixnine months ended JuneSeptember 30, 2019. Discontinued operations, net of taxes, for the three and sixnine months ended JuneSeptember 30, 2019 includes discrete tax benefits of $20 million associated with the favorable resolution of certain tax contingencies related to NID. In addition, net cash provided by operating activities in the consolidated statement of cash flows for the sixnine months ended JuneSeptember 30, 2019 included a $28 million refund from the taxing authorities related to discontinued operations.

18.    SUBSEQUENT EVENTS

    During October 2020, the Company amended its $600 million secured receivables credit facility in order to extend the maturity dates for each underlying commitment by one year while 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 2021 and a $250 million loan commitment maturing October 2022. Additionally, the Company can issue up to $100 million of letters of credit through October 2022. Borrowings under the facility are collateralized by certain domestic receivables. Interest on borrowings under the facility is based on either commercial paper rates for highly-rated issuers or LIBOR, plus a spread of 0.825% to 0.95%.

    In October 2020, the Company issued a redemption notice to the holders of the Company's $550 million aggregate principal amount of 4.70% senior notes due April 2021, to redeem such notes in November 2020. Upon redemption, the Company will recognize a loss on extinguishment of debt based on the difference between the reacquisition price of the debt and the net carrying amount. The Company will pay a redemption premium in accordance with the requirements of such notes using a treasury rate calculated on the third business day preceding the redemption date.

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 over 95% of our consolidated net revenues.

    We assess our revenue performance for the DIS business based upon, among other factors, volume (measured by test requisitions) and revenue per requisition.

    Each requisition accompanies patient specimens, indicating the test(s) to be performed and the party to be billed for the test(s). Management utilizes requisition data to assist with assessing the growth of the business. Therefore, we believe that the change in the number of requisitions from period to period is useful information for investors as it allows them to assess our growth.

    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. Management utilizes revenue per requisition data in order to assist with assessing various factors impacting the performance of the business, including pricing and trends impacting mix. Therefore, we believe that the change in this metric from period to period is useful information for investors as it allows them to assess such factors, which are relevant to assessing the revenue performance of the business.

    Diagnostic Solutions

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

Impact of COVID - 19

    As a novel strain of coronavirus (“COVID-19”) continues to spread and severely impact the economy of the United States and other countries around the world, we are committed to being a part of the coordinated public and private sector response to this unprecedented challenge. We have made substantial investments to expand the amount of COVID-19 testing available to the country and are currently capable of performing up to 130,000more than 200,000 COVID-19 molecular diagnostic tests per day to aid in the diagnosis of COVID-19 and approximately 200,000 COVID-19 antibody tests per day to aid in the detection of immune response. Despite our increase in capacity, surging demand for COVID-19 molecular diagnostic tests recently has increased faster than our capacity to perform the testing, which has impacted the time it takes for us to deliver test results to patients. We are continuing to invest in ways to increase our ability to bring more COVID-19 molecular testing to patients and speed the delivery of test results. However, global supply constraints have limited, and may continue to limit, our ability to do so. In the near future, we expect to have the capacity to perform approximately 150,000 molecular diagnostic tests per day. We have been effectively managing challenges in the global supply chain; and, at this point, we have sufficient supplies to conduct our business.

    We have put preparedness plans in place at our facilities to maintain continuity of operations, while also taking steps to keep colleagues and customers healthy and safe. In line with recommendations to reduce large gatherings and increase social distancing, we have transitioned many of our office-based colleagues toare working in a remote work environment. We are evaluating the best way to bring them back into the office.

    During January and February 2020, we experienced growth in DIS revenues and volumes compared to the prior year period. However, in March and April 2020, we experienced a material decline in testing volumes due to the COVID-19 pandemic. During the last two weeks of March, volumes declined in excess of 40% compared to the prior year period, inclusive of COVID-19 testing, which continued in April with volume declines in the range of 50 to 60% compared to the prior year period as government policies were implemented to reduce the transmission of COVID-19. During May and June 2020, we began to experience a recovery in base testing volumes (which excludes COVID-19 molecular and antibody testing), as well aswhich continued in the third quarter of 2020. Additionally, beginning during the second quarter, we experienced growing demand for COVID-19 testing services.services and have expanded our capacity in order to satisfy such demand. Volumes in our base business for the second and third quarters of 2020 decreased approximately 34% and 5%, respectively, compared to the prior year periods.

    The recoverydecrease in base testing volumes was more significant in the geographies where governmental policies designed to reduce the transmission of COVID-19 were eased more quickly than other geographies. Volumes in our base business (which excludes COVID-19 molecular and antibody testing) for the second quarter of 2020 decreased approximately 34% compared to the prior year period, which was partially offsetdriven by COVID-19 molecular and antibody testing, as well as an increase in revenue per requisition driven in large part by reimbursement for COVID-19 molecular testing.

        DIS revenues were positively impacted in the period as a result of the April 2020 announcement by the Centers for Medicare and Medicaid Services that it would increase the reimbursement for certain COVID-19 molecular tests making use of high-throughput technologies developed by the private sector that allow for increased testing capacity, faster results, and more effective means of combatting the spread of the virus to $100 per test, effective April 14, 2020 through the duration of the COVID-19 national emergency. If the current public health emergency is not renewed, reimbursement for such tests will revert to the initial rate of $51 per test.

        Federal,federal, state and local governmental policies and initiatives designed to reduce the transmission of COVID-19 which have resulted in, among other things, a significant reduction in physician office visits, the cancellation of elective medical procedures, customers closing or severely curtailing their operations (voluntarily or in response to government orders), and the adoption of work-from-home policies, all of which have had, and we believe will continue to have, an impact on our operating results, financial position and cash flows, including continued declines in base testing volumes (which excludes COVID-19 molecular and antibody testing).volumes. It is also possible that we will experience an adverse impact on cash collections as a result of the impact of the COVID-19 pandemic. 

    During the second quarter of 2020, the decrease in base testing volumes was partially offset by COVID-19 molecular and antibody testing, including an increase in revenue per requisition driven in large part by COVID-19 molecular testing. During the third quarter of 2020, the decrease in base testing volumes was more than offset by the impact of the COVID-19 testing.

    In April 2020 the Centers for Medicare and Medicaid Services ("CMS") announced that it would increase the reimbursement for certain COVID-19 molecular tests making use of high-throughput technologies developed by the private sector that allow for increased testing capacity, faster results, and more effective means of combating the spread of the virus to $100 per test, effective April 14, 2020. In October 2020, CMS announced that, beginning January 1, 2021, Medicare will change the base reimbursement rate for COVID-19 diagnostic tests run on high-throughput technologies to $75 per test with an additional payment of $25 per test if certain additional requirements are met. In conjunction with our trade association, we are currently reviewing how this reimbursement policy will impact laboratories and the patients we serve.

    In order to mitigate the impact that the COVID-19 pandemic had on our business, we implemented a series of temporary actions in April 2020 to manage our workforce costs and preserve cash including temporary salary reductions; suspension of certain benefits; reduced hours for employees whose work has significantly declined; and approved furloughs for employees with diminished work requirements who expressed an interest. Recently, asAs our testing volumes started to recover, we have recalled the vast majority of employees from furlough and reinstated full working hours for almost all employees who were asked to work reduced hours. Salary has beenBy the end of the third quarter of 2020, salaries were restored for the majority ofall exempt employees that had temporary salary reductions, with the remainder scheduled to be restored by the end of July 2020.reductions.

    We believe the COVID-19 pandemic’s impact on our consolidated results of operations, financial position and cash flows will be primarily driven by: the severity and duration of the COVID-19 pandemic; the COVID-19 pandemic’s impact on the U.S. healthcare system and the U.S. economy; and the timing, scope and effectiveness of federal, state and local

31

governmental responses to the COVID-19 pandemic. We may also be impacted by changes in the severity of the COVID-19
30

pandemic at different times in the various cities and regions where we operate and offer services. Even after the COVID-19 pandemic has moderated and the business and social distancing restrictions have eased, we may continue to experience similar adverse effects to our businesses, consolidated results of operations, financial position and cash flows resulting from a recessionary economic environment that may persist. In the longer term, given the many challenges that hospitals will face, we may have more opportunities to partner with hospitals to help achieve their laboratory strategies, and the COVID-19 pandemic may also be a further catalyst for consolidation in the laboratory testing industry.

The Coronavirus Aid, Relief, and Economic Security Act (CARES Act)

    In March 2020, in response to the COVID-19 pandemic, the CARES Act was signed into law. The CARES Act provides numerous tax provisions and other stimulus measures, including temporary changes regarding the prior and future utilization of net operating losses, temporary changes to the prior and future limitations on interest deductions, temporary suspension of certain payment requirements for the employer portion of Social Security taxes, technical corrections from prior tax legislation for tax depreciation of certain qualified improvement property, and the creation of certain payroll tax credits associated with the retention of employees. DuringBeginning in the three months ended June 30,second quarter of 2020, we started taking advantage of the temporary suspension of payment requirements for the employer portion of Social Security taxes.

    The CARES Act also includes a number of benefits that are applicable to us and other healthcare providers including, but not limited to:

providing coverage for COVID-19 testing at no out-of-pocket cost to nearly all patients;
providing clinical laboratories a one-year reprieve from the reporting requirements under the Protecting Access to Medicare Act ("PAMA") as well as a one-year delay of reimbursement rate reductions for clinical laboratory services provided under Medicare that were scheduled to take place in 2021. Further revisions of the Medicare Clinical Laboratory Fee Schedule for years after 2021 will be based on future surveys of market rates. Reimbursement reduction from 2022-2024 is capped by PAMA at 15% annually;
appropriating $100 billion to health care providers for related expenses or lost revenues that are attributable to the COVID-19 pandemic. In April 2020 and August 2020, we received approximately $65 million from the initial trancheand $73 million, respectively, of funds from the government that were distributed to health care providers. In addition, pursuanthealthcare providers for related expenses or lost revenues that are attributable to certain rules and regulations promulgated by the U.S. Department of Health and Human Services ("HHS"), we applied for additional funds to be distributed by the government under the original $100 billion appropriation to healthcare providersCOVID-19 pandemic under the CARES Act. In October 2020, we announced that we plan to return the entire $138 million of funds received. During the three months ended June 30, 2020, we recognized $65 million in other operating expense (income), net related to the first tranche of funds. During the three months ended September 30, 2020, we reversed the $65 million of funds that had previously been recognized in other operating expense (income), net. As of September 30, 2020, no amounts are recorded in our year-to-date consolidated statement of operations and the entire $138 million of funds that we intend to return are recorded in accounts payable and accrued expenses on our consolidated balance sheet; and
suspending Medicare sequestration from May 2020 to December 2020. We estimate that theThe suspension of the Medicare sequestration will resulthas resulted in a small benefit to us in the form of higher reimbursement rates for diagnostic testing services performed on behalf of Medicare beneficiaries.

Retirement of Debt

    During January 2020, we redeemed in full the outstanding indebtedness under our senior notes due January 2020 and senior notes due March 2020 using proceeds from the issuance, in December 2019, of the 2.95% senior notes due June 2030, along with cash on hand. For the sixnine months ended JuneSeptember 30, 2020, we recorded a loss on retirement of debt, principally comprised of premiums paid, of $1 million in other income, (expense), net.

Senior Notes Offering

    During May 2020, we completed a senior notes offering, consisting of $550 million aggregate principal amount of 2.80% senior notes due June 2031 (the “2031 Senior Notes”), which were issued at an original issue discount of $1 million. We expectIn October 2020, we issued a redemption notice to use the net proceeds from the offering for general corporate purposes, which may include the redemption or repaymentholders of indebtedness including our $550 million aggregate principal amount of 4.70% senior notes due April 2021.2021, to redeem such notes in November 2020. We intend to use the net proceeds from the 2031 Senior Notes, along with cash on hand, to satisfy the redemption.

Acquisition of Blueprint Genetics Oy

    On January 21, 2020, we completed the acquisition of Blueprint Genetics Oy ("Blueprint Genetics"), in an all cash transaction for $108 million, net of $3 million cash acquired. Blueprint Genetics is a leading specialty genetic testing company with deep expertise in gene variant interpretation based on next generation sequencing and proprietary bioinformatics. Through the acquisition, we acquired all of Blueprint Genetics' operations. The acquired business is included in our DIS business.    

Acquisition of the Outreach Laboratory Services Business of Memorial Hermann Health System

    On April 6, 2020, we completed the acquisition of select assets which constitute substantially all of the operations of Memorial Hermann Diagnostic Laboratories, the outreach laboratory division of Memorial Hermann Health System ("Memorial Hermann") in an all cash transaction for $120 million. Memorial Hermann is a not-for-profit health system in Southeast Texas. The acquired business is included in our DIS business.

Agreement to AcquireAcquisition of the Remaining 56% Interest in Mid America Clinical Laboratories, LLC

    On June 22,August 1, 2020, we entered into definitive agreements with our joint venture partners to acquire theircompleted the acquisition of the remaining 56% interest in Mid America Clinical Laboratories, LLC ("MACL"), which from our joint venture partners in an all cash transaction for $93 million, net of $18 million cash acquired. MACL is the largest independent clinical laboratory provider in Indiana. Prior to the acquisition, we currently accountaccounted for our 44% interest in MACL as an equity method investment. Closing of the transaction,investment which is expected to occur during the third quarter of 2020, remains subject to customary closing conditions. Upon close of the transaction, MACL will become a wholly owned subsidiary of the Company and we expect to remeasure our previously held equity interest in MACLwas remeasured to its fair value of $87 million on the acquisition date, fair value and recognizeresulting in a gain of $70 million that was recognized in ourother income, net in the consolidated statements of operations. As a result of the acquisition, MACL became our wholly owned subsidiary. The acquired business is included in our DIS business.

    For further details regarding our acquisitions, see Note 5 to the interim unaudited consolidated financial statements and Note 6 to the audited consolidated financial statements in our 2019 Annual Report on Form 10-K.

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. We are assessing whether the COVID-19 pandemic will impact our ability to achieve that objective in 2020.

    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 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 sixnine months ended JuneSeptember 30, 2020, we incurred $21$34 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 4 to the interim unaudited consolidated financial statements.    

Critical Accounting Policies and Estimates
    
    There have been no significant changes to our critical accounting policies from those disclosed in our 2019 Annual Report on Form 10-K except for the adoption of new accounting standards as described in Note 2 to the interim unaudited consolidated financial statements.

    Revenues and accounts receivable associated with DIS

32
33

    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 primarily 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. The portfolios determined using the portfolio approach consist of the following customers:

Healthcare Insurers
Government Payers (Medicare and Medicaid programs)
Client Payers
Patients

    We have a standardized approach to estimate the amount of consideration that we expect to be entitled to; this standardized approach considers, among other things, 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), as well as other factors including current market conditions, are integral parts 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, based on actual receipts, may be recorded upon settlement.

    Although we believe that our estimates for contractual allowances and patient price concessions as well as our allowance for credit losses are appropriate, it is possible that we will experience an adverse impact on cash collections as a result of the impact of the COVID-19 pandemic. For further details on revenue and receivables, see Note 15 to the interim unaudited consolidated financial statements.

     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.
    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, we are required to perform the quantitative goodwill impairment test. Otherwise, no further analysis is required.
    On a quarterly basis, we perform a review of our business to determine if events or changes in circumstances have occurred that indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying value. 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. In conjunction with the preparation of our JuneSeptember 30, 2020 financial statements, we performed such review and concluded that no impairment test was necessary. However, should the impact of the COVID-19 pandemic be significantly worse than currently expected, it is possible that we could incur impairment charges in the future.

Impact of New Accounting Standards

    The adoption of new accounting standards is discussed in Note 2 to the interim unaudited consolidated financial statements.

    The impact of recent accounting pronouncements not yet effective on our consolidated financial statements is discussed in Note 2 to the interim unaudited consolidated financial statements.

    For both the three and sixnine months ended JuneSeptember 30, 2020, we utilized the most likely estimate of our annual income before taxes to determine the annual effective income tax rate for 2020. As a result of uncertainty associated with the impact of the COVID-19 pandemic, it is possible that we will experience variability in the annual projections and, as a result, the annual effective income tax rate. We will update the annual effective income tax rate each quarter during 2020 for changes in the latest projections for the Company.

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 historically 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 results of operations or financial position.
    
    As of both JuneSeptember 30, 2020 and December 31, 2019, the fair value of our debt was estimated at approximately $5.2 billion and $5.1 billion, respectively, principally 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 JuneSeptember 30, 2020 and December 31, 2019, the estimated fair value exceeded the carrying value of the debt by $481$609 million and $313 million, respectively. A hypothetical 10% increase in interest rates (representing 1917 basis points as of JuneSeptember 30, 2020 and 28 basis points as of December 31, 2019) would potentially reduce the estimated fair value of our debt by approximately $94$84 million and $100 million as of JuneSeptember 30, 2020 and December 31, 2019, 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. As of JuneSeptember 30, 2020, interest on our senior unsecured revolving credit facility is subject to a pricing schedule that can fluctuate based on changes in our credit ratings and our leverage ratio. As such, our borrowing cost under this credit arrangement will be subject to fluctuations in interest rates, our leverage ratio and changes in our credit ratings. As of JuneSeptember 30, 2020, 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%. During October 2020, we amended the secured receivables credit facility and the borrowing rates are now based on commercial paper rates for highly rated issuers, or LIBOR, plus a spread of 0.825% to 0.95%. As of JuneSeptember 30, 2020, there were no borrowings outstanding under either our $600 million secured receivables credit facility or our $750 million senior unsecured revolving credit facility. The amendment to the secured receivables credit facility did not change the total borrowing capacity under the facility.

    In April 2020, we terminated our existing fixed-to-variable interest rate swap agreements. Based on our remaining net exposure to interest rate changes, a hypothetical 10% change to the variable rate component of our variable rate indebtedness would not materially change annual interest expense.

    During March 2020, we entered into a forward-starting interest rate swap agreement with a financial institution for a total notional amount of $25 million. Additionally, during May 2020, we entered into interest rate lock agreements with several financial institutions for a total notional amount of $275 million. The forward-starting interest rate swap agreement and the interest rate lock agreements were entered into in order 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 and were accounted for as cash flow hedges. In connection with the issuance of the 2031 Senior Notes, these agreements were settled

and we received net proceeds of $1 million. The net gain is deferred in stockholders' equity, net of taxes, as a component of accumulated other comprehensive loss, and is being amortized as an adjustment to interest expense, net over a ten-year period.

    For further details regarding our outstanding debt, see NoteNotes 8 and 18 to the interim unaudited consolidated financial statements and Note 13 to the audited consolidated financial statements included in our 2019 Annual Report on Form 10-K.

    Risk Associated with Investment Portfolio

    Our investment portfolio includes equity investments comprised primarily of strategic 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 JuneSeptember 30, 2020.

    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.

    In conjunction with the preparation of our JuneSeptember 30, 2020 financial statements, we considered whether the carrying values of such investments were impaired and concluded that no such impairment existed. However, should the impact of the COVID-19 pandemic be worse than currently expected, it is possible that we could incur impairment charges in the future.

    As of JuneSeptember 30, 2020, approximately 4%2% of our $988$1,605 million of consolidated cash and cash equivalents were held outside of the United States. As a result of changes introduced by the Tax Cuts and Jobs Act, 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 sixnine months ended JuneSeptember 30, 2020 and 2019 was $602$1,464 million and $596$895 million, respectively. The $6$569 million increase in net cash provided by operating activities for the sixnine months ended JuneSeptember 30, 2020, compared to the prior year period was primarily a result of:

higher operating income in 2020 as compared to 2019;
$65138 million of proceeds in 2020 that we received in 2020 from the initial tranche of funds that were appropriated to healthcare providers under the CARES Act;Act (during October 2020 we announced our plan to return such funds);
timing of movements in our working capital accounts including as a $63 million decrease in tax payments;result of the temporary suspension of certain payment requirements for the employer portion of Social Security taxes; and
$40 million of proceeds received in 2020 from the termination of interest rate swaps; and
timing of movements in other working capital accounts; partially offset by
lower operating income in 2020 as compared to 2019; and
higher performance-based compensation payments in 2020 compared to 2019.2019; and

a $28 million refund received in the prior year period from the taxing authorities associated with the favorable resolution of certain tax contingencies related to a discontinued operation.
    
    Days sales outstanding, a measure of billing and collection efficiency, was 4447 days as of JuneSeptember 30, 2020, 54 days as of December 31, 2019 and 5152 days as of JuneSeptember 30, 2019. The decrease in DSO is partially due to recent fluctuations in our monthly revenue due to the impact of the COVID-19 pandemic. Although we believe that our current revenue reserves and allowance for credit losses are appropriate, it is possible that we will experience an adverse impact on cash collections as a result of the impact of the COVID-19 pandemic.

    Cash Flows from Investing Activities

    Net cash used in investing activities for the sixnine months ended JuneSeptember 30, 2020 and 2019 was $411$604 million and $202$311 million, respectively. This $209$293 million increase in cash used in investing activities for the sixnine months ended JuneSeptember 30, 2020, compared to the prior year period was primarily a result of:

    Cash Flows from Financing Activities

    Net cash used in financing activities for the sixnine months ended JuneSeptember 30, 2020 and 2019 was $395$447 million and $256$285 million, respectively. This $139$162 million increase in cash used in financing activities for the sixnine months ended JuneSeptember 30, 2020, compared to the prior year period was primarily a result of:

$252253 million of net debt repayments (repayments of debt less proceeds of borrowing)from borrowings) in 2020 compared to $36 million of net borrowings in 2019; partially offset by
a $58$78 million changedecrease in bank overdrafts, which are generally settled in cash the following business day;repurchases of our common stock (see "Share Repurchase Program" for further details); and
a $51$46 million increase in proceeds from the exercise of stock options, which was a result of an increase in the volume of stock options exercised and the average exercise price compared to the prior year;
a $28 million decrease in repurchases of our common stock (see "Share Repurchase Program" for further details); and
a $17 million decrease in distributions to noncontrolling interest partners.year.

    During the sixnine months ended JuneSeptember 30, 2020, we completed the issuance of the 2031 Senior Notes.

    Share Repurchase Program

    As of JuneSeptember 30, 2020, $1.2 billion remained available under our share repurchase authorizations; however, in April 2020, we temporarily suspended additional share repurchases under the existing authorization through the end of 2020.authorization. The share repurchase authorization has no set expiration or termination date.

    A description of the terms of our indebtedness and related debt service requirements and future payments of our outstanding debt is contained in Note 8 to the interim unaudited consolidated financial statements and Note 13 to the audited consolidated financial statements in our 2019 Annual Report on Form 10-K.
    
    Interest payments on our outstanding debt include interest associated with finance lease obligations and have been calculated using the interest rates as of JuneSeptember 30, 2020 applied to the JuneSeptember 30, 2020 balances, which are assumed to remain outstanding through their maturity dates.

    Operating lease obligations include variable charges (primarily maintenance fees and utilities associated with our real estate leases) in effect as of JuneSeptember 30, 2020. A discussion and analysis regarding our operating lease obligations is contained in Note 14 to the audited consolidated financial statements in our 2019 Annual Report on Form 10-K.

    Purchase obligations include our noncancelable commitments to purchase products or services as described in Note 18 to the audited consolidated financial statements in our 2019 Annual Report on Form 10-K.

    Merger consideration obligations include consideration owed on our business acquisitions. For details regarding our acquisitions, see Note 5 to the interim unaudited consolidated financial statements and Note 6 to the audited consolidated financial statements in our 2019 Annual Report on Form 10-K.

As of JuneSeptember 30, 2020, our total liabilities associated with unrecognized tax benefits were approximately $89$79 million, which were excluded from the table above. We expect that these liabilities may decrease by less than $15$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 the timing of the future payments of these liabilities. See Note 8 to the audited consolidated financial statements in our 2019 Annual Report on Form 10-K 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 JuneSeptember 30, 2020, the fair value of the redeemable noncontrolling interest on the interim unaudited consolidated balance sheet was $77$80 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 10 to the interim unaudited consolidated financial statements and Note 16 to the audited consolidated financial statements in our 2019 Annual Report on Form 10-K.

    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,venture, which are accounted for under the equity method of accounting. Our investment in equity method investees is less than 5% of our consolidated total assets. Our proportionate share of income before income taxes associated with our equity method investees is approximatelyless than 5% of our consolidated income from continuing operations before income taxes and equity in earnings of equity method investees. We partially guarantee a lease obligation of one of our equity method investees, payment under such guarantee is not likely at this time and we have no other material unconditional obligations or guarantees to, or in support of, our equity method investees and their operations.

Table of Contents
    In conjunction with the preparation of our JuneSeptember 30, 2020 financial statements, we considered whether the carrying values of our equity method investments were impaired and concluded that no such impairment existed. However, should the impact of the COVID-19 pandemic be worse than currently expected, it is possible that we could incur impairment charges in the future.

    For further details regarding related party transactions with our equity method investees, see Note 14 to the interim unaudited consolidated financial statements and Note 20 to the audited consolidated financial statements in our 2019 Annual Report on Form 10-K.
    
    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 and consumer growth strategies.

    Together with the Quest Diagnostics Foundation, we launched a multi-year initiative to reduce health disparities in underserved communities, including those impacted by the COVID-19 pandemic. As part of this initiative, we plan to donate testing services and fund a range of initiatives estimated to total more than $100 million aimed at improving access to testing and awareness of the value of diagnostic insights in managing overall health.

    In April 2020 and August 2020, we received approximately $65 million and $73 million, respectively, of funds from the government that were distributed to healthcare providers for related expenses or lost revenues that are attributable to the COVID-19 pandemic under the CARES Act. During October 2020, we announced our plan to return the entire $138 million of funds received.

As of JuneSeptember 30, 2020, we had cash and cash equivalents on hand of $988 million and had $1.3 billion of borrowing capacity available under our existing credit facilities, including $529 million available under our secured receivables credit facility and $750 million available under our senior unsecured revolving credit facility. There were no outstanding borrowings under these credit facilities as of JuneSeptember 30, 2020. The secured receivables credit facility includes a $250 million loan commitment which matures in October 2020,2021, and a $250 million loan commitment and a $100 million letter of credit facility which mature in October 2021.2022. The senior unsecured revolving credit facility matures in March 2023. For further details regarding the credit facilities, see Note 13 to the audited consolidated financial statements in our 2019 Annual Report on Form 10-K and NoteNotes 8 and 18 to the interim unaudited consolidated financial statements.

    Our secured receivables credit facility is subject to customary affirmative and negative covenants, and certain financial covenants with respect to the receivables that comprise the borrowing base and secure the borrowings under the facility. Our senior unsecured revolving credit facility is also subject to certain financial covenants and limitations on indebtedness. As of JuneSeptember 30, 2020, we were in compliance with all such applicable financial covenants.

    We believe that the COVID-19 pandemic has had and may continue to have an adverse impact our consolidated results of operations, financial position, and cash flows, including material declines in testing volumes for our base business (which excludes COVID-19 molecular and antibody testing), the extent of which will continue to be primarily driven by: the severity and duration of the COVID-19 pandemic; the COVID-19 pandemic’s impact on the U.S. healthcare system and the U.S. economy; and the timing, scope and effectiveness of federal, state and local governmental responses to the COVID-19 pandemic. It is also possible that we will experience an adverse impact on cash collections of our accounts receivable as a result of the impact of the COVID-19 pandemic.

    We have takentook certain actions to preserve liquidity. We have temporarily suspended share repurchases under our existing share repurchase authorization, and, in April 2020, implemented a series of temporary actions to manage our workforce costs.

    In addition, we have takentook certain steps to ensure adequate access to liquidity. In April 2020, we entered into an amendment to our senior unsecured revolving credit facility in order to provide for increased flexibility. Pursuant to the amendment, the leverage ratio covenant was increased from the second quarter of 2020 as follows:
43

Table of Contents
As of:Applicable Covenant:
June 30, 2020no more than 5 times EBITDA
September 30, 2020no more than 5.5 times EBITDA
December 31, 2020no more than 6.5 times EBITDA
March 31, 2021no more than 6.25 times EBITDA
June 30, 2021no more than 4.5 times EBITDA

44

Table of Contents
    
    Thereafter, the leverage ratio covenant reverts to no more than 3.5 times EBITDA. During the period that the increased covenant applies, which period may be terminated early by us provided that we are in compliance with the historical 3.5 times EBITDA leverage ratio, the amended credit agreement contains certain additional limitations and restrictions including, but not limited to, repurchases of our common stock, the amount of funds that can be used on business acquisitions, the incurrence of secured indebtedness and the payment of dividends. Interest on the amended senior unsecured revolving credit facility is subject to a pricing schedule that can fluctuate based on changes in our credit ratings and current EBITDA leverage ratio.

    In addition, in May 2020, we completed a senior notes offering, consisting of $550 million aggregate principal amount of 2.80% senior notes due June 2031, which were issued at an original issue discount of $1 million. We expectIn October 2020, we issued a redemption notice to use the net proceeds from the offering for general corporate purposes, which may include the redemption or repaymentholders of indebtedness including our $550 million aggregate principal amount of 4.70% senior notes due April 2021.2021, to redeem such notes in November 2020. We intend to use the net proceeds from the 2031 Senior Notes, along with cash on hand, to satisfy the redemption.

    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, and additional growth opportunities for the foreseeable future. However, should it become necessary, we believe that our credit profile should provide us with access to additional financing in order to fund normal business operations, make interest payments, fund growth opportunities and satisfy upcoming debt maturities.

Item 1A. Risk Factors

    Item 1A. of our Annual Report on Form 10-K for the year ended December 31, 2019 and Part II, Item 1A. of our Quarterly Report on Form 10-Q for the quarter ended March 31,June 30, 2020 include a discussion of our risk factors. There have been no material changes in the risk factors described in those reports, except as discussed below.reports.

The COVID-19 pandemic has significantly and adversely affected our consolidated results of operations, financial position and cash flows, and may continue to do so.

A pandemic caused by a novel strain of coronavirus (“COVID-19”) continues to spread and severely impact the economy of the United States and other countries around the world. Federal, state and local governmental authorities in the United States have implemented numerous policies and initiatives to try and reduce the transmission of COVID-19, such as travel bans and restrictions, quarantines, shelter-in-place orders, and business shutdowns. These policies and initiatives have resulted in, among other things, a significant reduction in physician office visits, the cancellation of elective medical procedures, customers closing or severely curtailing their operations (voluntarily or in response to government orders), and the adoption of work-from-home policies, all of which have had, and we believe will continue to have, an impact on the Company’s consolidated results of operations, financial position and cash flows.

        Due to the COVID-19 pandemic, the Company has experienced significant volatility, including periods of material decline compared to prior year periods, in testing volumes in the Company’s base business (which excludes COVID-19 molecular and antibody testing) and it expects this volatility, including periods of material decline, will continue.

Although the Company also has experienced heavy demand for COVID-19 molecular testing as a result of the COVID-19 pandemic, which has had a positive impact on its overall testing volume, the duration and level of the demand for COVID-19 molecular testing is uncertain. Further, the existing $100 Medicare reimbursement for COVID-19 molecular testing is tied to the public health emergency declared by the U.S. Department of Health and Human Services, and will, unless extended, revert to a lower reimbursement rate.

The Company may also experience an adverse impact on cash collections and supply chain disruptions, including shortages, delays and price increases in testing equipment and supplies, as a result of the impact of the COVID-19 pandemic. Any of these events could have an adverse impact on our business, consolidated results of operation, financial position and cash flows.

The Company believes the COVID-19 pandemic’s adverse impact on its consolidated results of operations, financial position and cash flows will be primarily driven by: the severity and duration of the COVID-19 pandemic; the COVID-19 pandemic’s impact on the U.S. healthcare system and the U.S. economy; and the timing, scope and effectiveness of federal, state and local governmental responses to the COVID-19 pandemic. These primary drivers are beyond the Company’s knowledge and control and will change over time, and as a result, at this time the Company cannot reasonably estimate the adverse impact the COVID-19 pandemic will have on its businesses, consolidated results of operations, financial position and cash flows, and the adverse impact may be material. The Company’s business also may be impacted by changes in the severity of the COVID-19 pandemic at different times in the various cities and regions where it operates and offers services. Even after the COVID-19 pandemic has moderated and the business and social distancing restrictions have eased, the Company may continue to experience similar adverse effects to its businesses, consolidated results of operations, financial position and cash flows resulting from a recessionary economic environment that may persist. The impact that the COVID-19 pandemic will have on our businesses, consolidated results of operations, financial position and cash flows could exacerbate the risks identified in “Item 1A. Risk Factors” in our Annual Report on Form 10-K.
