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 2015 Annual Report on Form 10-K. The year-end balance sheet data was derived from the audited financial statements as of December 31, 2015, but does not include all the disclosures required by accounting principles generally accepted in the United States (“GAAP”).
Reclassifications
As a result of the early adoption of the accounting standard update ("ASU") associated with simplifying several aspects of stock-based compensation, certain reclassifications have been made to the prior period financial statements to conform with the current period presentation. For further details regarding the impact of the ASU, see New Accounting Pronouncements.
Use of Estimates
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.
Property, Plant and Equipment
In connection with the Company’s annual review of the estimated useful lives of its property, plant and equipment completed during the first quarter of 2016, the Company revised the estimated useful lives of certain classes of its property, plant and equipment. In order to better reflect the Company's current expectations regarding the use of its assets, the recent operational improvements from its Invigorate program and considering historical and other data, the Company revised the estimated useful lives of its laboratory equipment from a range of five to seven years to a range of seven to ten years, furniture and fixtures from a range of three to seven years to a range of five to twelve years and computer software obtained for internal use from three years to five years. The change in estimated useful lives was accounted for prospectively as a change in accounting estimate effective in the first quarter of 2016. The impact of this change for the three months ended September 30, 2016, was a decrease in depreciation expense and an increase in operating income of $9 million and an increase in net income of $6 million, or $0.04 per share on a basic and diluted basis. The impact of this change for the nine months ended September 30, 2016, was a decrease in depreciation expense and an increase in operating income of $29 million and an increase in net income of $18 million, or $0.12 per share on a basic and diluted basis. The full year impact for 2016 is expected to be a decrease in depreciation expense and an increase in operating income of approximately $36 million and an increase in net income of approximately $22 million, or $0.16 per share on a basic and diluted basis.
New Accounting Pronouncements
New Accounting Standards To Be Adopted
In May 2014, the Financial Accounting Standards Board ("FASB") issued an ASU on revenue recognition. This ASU outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers. This standard supersedes existing revenue recognition requirements and eliminates most industry-specific guidance from GAAP. The core principle of the revenue recognition standard is to require an entity to recognize as revenue the amount that reflects the consideration to which it expects to be entitled in exchange for goods or services as it transfers control to its customers. The standard requires additional disclosures including those that are qualitative and quantitative disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB deferred the effective date of this ASU to the first quarter of 2018, with early adoption permitted beginning in the first quarter of 2017. The ASU can be applied using a full retrospective method or a modified retrospective method of adoption. The Company is currently assessing the impact of the adoption of this ASU on the Company’s results of operations, financial position and cash flows.
In January 2016, the FASB issued an ASU on the recognition and measurement of financial assets and financial liabilities. This ASU requires that all equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) be measured at fair value with changes in fair value recognized in net income. However, companies may elect to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. In addition, the ASU eliminates the requirement to disclose the method and significant assumptions used to estimate the fair value for financial instruments measured at amortized cost on the balance sheet. The ASU is effective for the Company in the first quarter of 2018. The Company does not expect the adoption of this ASU to have a material impact on its results of operations, financial position and cash flows.

In February 2016, the FASB issued an ASU that amends accounting for leases. Under the new guidance, a lessee will recognize assets and liabilities for most leases on its balance sheet but will recognize expense on its statement of operations similar to current lease accounting. The ASU is effective for the Company in the first quarter of 2019 with early adoption permitted. The new guidance must be adopted using a modified retrospective transition approach, and provides for certain practical expedients. The adoption of this ASU will result in a significant increase to the Company’s balance sheet for lease liabilities and right-of-use assets, which has not yet been quantified. The Company is currently evaluating this and the other effects of adoption of this ASU on its consolidated financial statements.
In March 2016, the FASB issued an ASU that simplifies the transition to the equity method of accounting by requiring adoption as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting as a result of an increase in the level of ownership interest or degree of influence, no retroactive adjustment of the investment is required. The ASU is effective for the Company in the first quarter of 2017 with early adoption permitted. The Company does not expect the adoption of this ASU to have a material impact on its results of operations, financial position and cash flows.
In June 2016, the FASB issued an ASU that changes the impairment model for most financial instruments, including trade receivables from an incurred loss method to a new forward-looking approach, based on expected losses. The estimate of expected credit losses will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. This ASU is effective for the Company in the first quarter of 2020 and must be adopted using a modified retrospective transition approach. The Company is currently assessing the impact of the adoption of this ASU on the Company’s results of operations, financial position and cash flows.
In August 2016, the FASB issued an ASU that clarifies how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The ASU is effective for the Company in the first quarter of 2018 with early adoption permitted and must be applied retrospectively to all periods presented. The Company is currently assessing the impact of the adoption of this ASU on the presentation and classification of the Company’s cash flows.
Adoption of New Accounting Standards
On January 1, 2016, the Company adopted a new accounting standard issued by the FASB which makes targeted amendments to the current consolidation guidance for variable interest entities and limited partnerships and similar entities. The adoption of this standard did not have a material impact on the Company's results of operations, financial position and cash flows.
On January 1, 2016, the Company prospectively adopted a new accounting standard issued by the FASB which provides guidance in determining whether a cloud computing arrangement includes a software license. If it is determined that a cloud computing arrangement does include a software license, the software element of the arrangement should be accounted for consistent with the acquisition of other software licenses. If the arrangement does not include a software license, it should be accounted for as a service contract. The adoption of this standard did not have a material impact on the Company's results of operations, financial position and cash flows.
On January 1, 2016, the Company prospectively adopted a new accounting standard issued by the FASB which requires that an acquirer recognize adjustments to provisional amounts in a business combination that are identified during the measurement period in the reporting period in which the adjustment amounts are determined, including the cumulative effect of the change in provisional amount as if the accounting had been completed at the acquisition date. The adoption of this standard did not have a material impact on the Company's results of operations, financial position and cash flows.
During the first quarter of 2016, the Company prospectively adopted a new accounting standard issued by the FASB that clarifies that a change in the counterparty to a derivative instrument that has been designated as a hedging instrument does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. The adoption of this standard did not have a material impact on the Company's results of operations, financial position and cash flows.

In March 2016, the FASB issued an ASU that simplifies several aspects of the accounting for stock-based compensation award transactions, including the income tax consequences, classification of awards as either equity or liabilities, classification on the statement of cash flows and accounting for forfeitures. In the second quarter of 2016, the Company elected to early adopt this standard, effective January 1, 2016. As a result:

• | Excess income tax benefits and deficiencies from stock-based compensation arrangements are recognized as a discrete item within income tax expense, rather than additional paid-in capital. The adoption of this provision, which was done on a prospective basis, resulted in the classification of $3 million and $7 million of tax benefits in income tax expense for the three and nine months ended September 30, 2016, respectively. In addition, excess income tax benefits and deficiencies are no longer considered when applying the treasury stock method for computing the effect of dilutive securities, which resulted in an increase in the effect of the dilutive securities for both the three and nine months ended September 30, 2016.

• | Excess income tax benefits from stock-based compensation arrangements are classified as an operating activity and cash paid for employee payroll tax withholdings by directly withholding shares are classified as a financing activity in the consolidated statements of cash flows. The adoption of these provisions, which was done on a retrospective basis, resulted in the reclassification of $4 million of excess tax benefits related to the settlement of stock-based compensation awards from financing to operating activities and $6 million of taxes paid related to employee payroll tax withholdings on stock issued under stock-based compensation plans from operating to financing activities for the nine months ended September 30, 2015.

In addition, the ASU permits the Company to make a policy election to either estimate the forfeitures expected to occur in order to determine the amount of compensation cost to be recognized in each period or to account for forfeitures in the period they occur. The Company elected to continue to estimate the forfeitures expected to occur in order to determine the amount of compensation cost to be recognized in each period.

4. RESTRUCTURING ACTIVITIES
Invigorate Program
During 2012, the Company committed to a course of action related to a multi-year program called Invigorate which is designed to reduce its cost structure. 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; service excellence; lab excellence; and billing excellence. From 2012 through 2014, the Invigorate program was intended to partially offset reimbursement pressures and labor and benefit cost increases; free up additional resources to invest in science, innovation and other growth initiatives; and enable us to improve service quality and operating profitability.
In January 2015, the Company adopted a course of action related to its multi-year Invigorate program to further reduce its cost structure through 2017. This multi-year course of action continues to focus on the flagship program opportunities and new key opportunities such as: standardizing processes, information technology systems, equipment and data; enhancing electronic enabling services; and enhancing reimbursement for work performed.
Restructuring Charges
The following table provides a summary of the Company's pre-tax restructuring charges for the three and nine months ended September 30, 2016 and 2015:

Total restructuring charges | $ | 3 |  |  | $ | 15 |  |  | $ | 9 |  |  | $ | 36 |

The restructuring charges incurred for the three and nine months ended September 30, 2016 are primarily associated with various workforce reduction initiatives as the Company continues to simplify and restructure its organization. Of the total restructuring charges incurred during the three months ended September 30, 2016, $1 million and $2 million were recorded in cost of services and selling, general and administrative expenses, respectively. Of the total restructuring charges incurred during the nine months ended September 30, 2016, $4 million and $5 million were recored in cost of services and selling, general and administrative expenses, respectively.
The restructuring charges incurred for the three and nine months ended September 30, 2015 are primarily associated with various workforce reduction initiatives as the Company continues to simplify and restructure its organization. Of the total restructuring charges incurred during the three months ended September 30, 2015, $12 million and $3 million were recorded in cost of services and selling, general and administrative expenses, respectively. Of the total restructuring charges incurred during the nine months ended September 30, 2015, $29 million and $7 million were recorded in cost of services and selling, general and administrative expenses, respectively.

The restructuring liability as of September 30, 2016 and December 31, 2015, which is included in accounts payable and accrued expenses, was $10 million and $19 million, respectively.
5. BUSINESS ACQUISITIONS
On February 29, 2016, the Company completed the acquisition of the outreach laboratory service business of Clinical Laboratory Partners, LLC ("CLP"), a wholly-owned subsidiary of Hartford HealthCare Corporation, in an all-cash transaction for $135 million. CLP provides clinical testing services to physicians, hospitals, clinics and long-term care facilities in Connecticut. The assets acquired principally consist of $91 million of tax deductible goodwill and $43 million of customer-related intangible assets, which are being amortized over a useful life of 15 years. The goodwill recorded primarily includes the expected synergies resulting from combining the operations of CLP with those of the Company and the value associated with an assembled workforce and other intangible assets that do not qualify for separate recognition. The acquired outreach laboratory service business of CLP is included in the Company's DIS business. For further details regarding business segment information, see Note 14.
Supplemental pro forma combined financial information has not been presented as the impact of the CLP acquisition is not material to the Company's consolidated financial statements.
For details regarding the Company's 2015 acquisitions, see Note 5 to the consolidated financial statements in the Company's 2015 Annual Report on Form 10-K.
6. DISPOSITION
Sale of Focus Diagnostics Products
On March 29, 2016, the Company entered into a definitive agreement to sell the assets of its non-core Focus Diagnostics products business ("Focus Diagnostics") to DiaSorin S.p.A. ("DiaSorin"). On May 13, 2016, the Company completed the sale of Focus Diagnostics for $300 million in cash, or $293 million net of transaction costs and working capital adjustments, which includes $25 million of proceeds held in escrow. For the nine months ended September 30, 2016, the Company recorded a $118 million pre-tax gain on disposition of business. The Company also recorded income tax expense of $84 million, consisting of $91 million of current income tax expense and a deferred income tax benefit of $7 million. The income tax expense resulted in an effective tax rate of 71.4%, which was significantly in excess of the statutory tax rate primarily due to a lower tax basis in the assets sold, specifically the goodwill associated with the disposition. Of the $91 million of current income tax expense, $68 million was paid in the third quarter of 2016 and $23 million was included in accounts payable and accrued expenses as of September 30, 2016 and is expected to be paid in the fourth quarter of 2016.
The assets disposed of consisted of $113 million of goodwill, $30 million of intangible assets, with the remaining $38 million consisting of accounts receivable, inventories and property, plant and equipment. In addition, the disposition included liabilities of $6 million. As of December 31, 2015, the assets to be disposed of as part of the transaction primarily consisted of $113 million of goodwill, with the remainder consisting of property, plant and equipment, inventories and intangible assets, which were classified and included in current assets held for sale.
In connection with the sale, the Company entered into a five year supply agreement with DiaSorin. The supply agreement, which does not include a minimum purchase commitment, enables the Company to purchase certain products and supplies used in its DIS business. Purchases by the Company under this supply agreement subsequent to the sale of Focus Diagnostics were not material.
Focus Diagnostics, prior to May 13, 2016, is included in all other operating segments and has not been classified as a discontinued operation. For further details regarding business segment information, see Note 14.
For details regarding the Company's 2015 dispositions and assets held for sale, see Note 6 to the consolidated financial statements in the Company's 2015 Annual Report on Form 10-K.

A full description regarding the Company's fair value measurements is contained in Note 7 to the consolidated financial statements in the Company's 2015 Annual Report on Form 10-K.
The Company offers certain employees the opportunity to participate in non-qualified supplemental deferred compensation plans. 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. Changes in the fair value of these securities are measured using quoted prices in active markets based on the market price per unit multiplied by the number of units held exclusive

(in millions, except per share data)
of any transaction costs. A corresponding adjustment for changes in fair value of the trading securities is also reflected in the changes in fair value of the deferred compensation obligation. The deferred compensation liabilities are classified within Level 2 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 obligations are classified within Level 2 because their inputs are derived principally from observable market data by correlation to the hypothetical investments.
The fair value measurements of the Company's interest rate swaps classified within Level 2 of the fair value hierarchy are model-derived valuations as of a given date in which all significant inputs are observable in active markets including certain financial information and certain assumptions regarding past, present and future market conditions.
Investment in available-for-sale equity securities represents an investment in registered shares of a publicly-held company. The Company's investment in available-for-sale equity securities is classified within Level 1 of the fair value hierarchy because the fair value is obtained from quoted prices in an active market.
In April 2014, and as further detailed in Note 5 to the consolidated financial statements in the Company's 2015 Annual Report on Form 10-K, the Company completed the acquisitions of Summit Health, Inc. ("Summit Health") and Steward Health Care Systems, LLC's laboratory outreach business ("Steward"). In connection with the acquisitions, the Company initially recorded an aggregate contingent consideration liability of $26 million. The contingent consideration liability was classified within Level 3 measured at fair value using a probability weighted and discounted cash flow method. These measurements are based on externally obtained inputs and management's probability assessments of the occurrence of triggering events, appropriately discounted considering the uncertainties associated with the obligations, as well as the likelihood of achieving financial targets. The initial probability estimate of the occurrence of such triggering events associated with the amounts the Company could be obligated to pay in future periods for both Summit Health and Steward was between 5% and 95%. The probability-weighted cash flows were then discounted using a discount rate of 1.5% to 2.8%. Based on actual 2015 results for Summit Health compared to the earn-out target included in the contingent consideration arrangement, no payment was required. Therefore, the fair value of the contingent consideration accrual associated with Summit Health was reduced to $0 in the second quarter of 2015, which resulted in a $13 million gain included in other operating income, net for the nine months ended September 30, 2015. The remaining contingent consideration associated with Steward is projected to be paid out in three equal annual installments, with a maximum payout of $4 million.
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. At September 30, 2016 and December 31, 2015, the fair value of the Company’s debt was estimated at $4.1 billion and $3.7 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.

2016 Senior Notes Offering
In May 2016, the Company completed a $500 million senior notes offering (the “2016 Senior Notes”). The offering consisted of $500 million in aggregate principal of 3.45% senior notes due June 2026, issued at a discount of $1 million. These senior notes are unsecured obligations of the Company and rank equally with the Company's other senior unsecured obligations. The senior notes do not have a sinking fund requirement. The Company incurred $4 million of costs associated with the 2016 Senior Notes, which is included as a reduction to the carrying amount of long-term debt and is being amortized over the term of the related debt.
The net proceeds from the 2016 Senior Notes were used to repay outstanding indebtedness under the senior unsecured revolving credit facility and the secured receivables credit facility and for general corporate purposes.
Retirement of Debt
In March 2016, the Company completed a cash tender offer to purchase up to $200 million aggregate principal amount of its 6.95% Senior Notes due July 2037 ("Senior Notes due 2037") and 5.75% Senior Notes due January 2040 ("Senior Notes due 2040"). The Company purchased $73 million of its Senior Notes due 2037 and $127 million of its Senior Notes due 2040.
In March 2015, the Company completed a cash tender offer to purchase up to $250 million aggregate principal amount of its Senior Notes due 2037 and Senior Notes due 2040. The Company purchased $176 million of its Senior Notes due 2037 and $74 million of its Senior Notes due 2040. In April 2015, the Company redeemed all of its 5.45% Senior Notes due November 2015, $150 million of its 3.20% Senior Notes due April 2016 and all of its 6.40% Senior Notes due July 2017.
For the nine months ended September 30, 2016 and 2015, the Company recorded a loss on retirement of debt, principally comprised of premiums paid, of $48 million and $144 million, respectively, in other income (expense), net.

10. 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 has entered into interest rate swaps. Interest rate swaps involve the periodic exchange of payments without the exchange of underlying principal or notional amounts. Net settlements between the counterparties are recognized as an adjustment to interest expense, net.
Interest Rate Derivatives – Cash Flow Hedges
From time to time, the Company has entered into various interest rate lock agreements and forward starting interest rate swap agreements to hedge part of the Company's interest rate exposure associated with the variability in future cash flows attributable to changes in interest rates.
In May 2016, the Company entered into interest rate lock agreements with several financial institutions for a total notional amount of $250 million which were accounted for as cash flow hedges. These agreements were entered into to hedge a portion of the Company’s interest rate exposure associated with variability in future cash flows attributable to changes in the ten-year treasury rates related to the planned issuance of the 2016 Senior Notes. In connection with the issuance of the 2016 Senior Notes, these agreements were settled, and the Company paid $1 million. These losses are deferred in stockholders’ equity, net of income taxes, as a component of accumulated other comprehensive loss, and amortized as an adjustment to interest expense, net over the term of the respective senior notes.
In March 2015, the Company entered into interest rate lock agreements with several financial institutions for a total notional amount of $350 million which were accounted for as cash flow hedges. These agreements were entered into to hedge a portion of the Company’s interest rate exposure associated with variability in future cash flows attributable to changes in the five-year, ten-year and thirty-year treasury rates related to the planned debt issuance in 2015. In connection with the 2015 senior notes offering, these agreements were settled and the Company received $3 million. These gains are deferred in stockholders’ equity, net of income taxes, as a component of accumulated other comprehensive loss, and amortized as an adjustment to interest expense, net over the term of the respective senior notes.
During the fourth quarter of 2013 and first quarter of 2014, the Company entered into various forward starting interest rate swap agreements for an aggregate notional amount of $150 million which were accounted for as cash flow hedges. In connection with the issuance of the 2015 senior notes offering, all of these agreements were settled, and the Company paid $17 million. These losses are deferred in stockholders’ equity, net of income taxes, as a component of accumulated other comprehensive loss, and amortized as an adjustment to interest expense, net over the term of the Senior Notes due 2025.
The total net loss, net of taxes, recognized in accumulated other comprehensive loss, related to the Company's cash flow hedges as of September 30, 2016 and December 31, 2015 was $11 million and $12 million, respectively. The loss recognized on the Company's cash flow hedges for the three and nine months ended September 30, 2016 and 2015, as a result of ineffectiveness, was not material. 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 $3 million.

Interest Rate Derivatives – Fair Value Hedges
The Company maintains various fixed-to-variable interest rate swaps to convert a portion of the Company's long-term debt into variable interest rate debt. A summary of the notional amounts of these interest rate swaps as of September 30, 2016 and December 31, 2015 is as follows:

|  |  |  | Notional Amount
Debt Instrument |  | Floating Rate Paid by the Company as of September 30, 2016 |  | September 30, 2016 |  | December 31, 2015
4.75% Senior Notes due January 2020 |  |  |  | $ | — |  |  | $ | 350 |
4.70% Senior Notes due April 2021 |  |  |  | — |  |  | 400 |
4.25% Senior Notes due April 2024 |  | One-month LIBOR plus a 3.02% spread |  | 250 |  |  | 250 |
3.50% Senior Notes due March 2025 |  | One-month LIBOR plus a 2.24% to 2.28% spread |  | 600 |  |  | 200 |
3.45% Senior Notes due June 2026 |  | One-month LIBOR plus a 2.15% spread |  | 350 |  |  | — |
|  |  |  | $ | 1,200 |  |  | $ | 1,200 |

As of December 31, 2015, the Company had entered into various fixed-to-variable interest rate swap agreements with an aggregate notional amount of $1.2 billion and variable interest rates ranging from one-month LIBOR plus 1.4% to one-month LIBOR plus 3.6%. In July 2016, the Company terminated those interest rate swaps agreements. As a result of the termination, the Company received proceeds of $60 million, which included $6 million of accrued interest. The remaining basis adjustment on the respective debt obligation of $54 million will be amortized as a reduction of interest expense over the remaining terms of the hedged debt instrument. Immediately after the termination of these interest rate swaps, the Company entered into new fixed-to-variable interest rate swap agreements, which are reflected in the table above.
Since inception, the fair value hedges have been effective or highly effective; therefore, there is no impact on earnings for the three and nine months ended September 30, 2016 and 2015 as a result of hedge ineffectiveness.
Interest Rate Derivatives - Economic Hedges
In March 2016, in connection with the retirement of debt discussed in Note 9, the Company entered into reverse interest rate lock agreements with several financial institutions which were not designated for hedge accounting. The Company entered into these agreements to hedge the variability in cash flows associated with $75 million of the $200 million principal amount of debt that was retired in the first quarter of 2016. These agreements were settled during the first quarter of 2016 resulting in a gain of $1 million which was recognized in other income (expense), net.
In March 2015, in connection with the 2015 retirement of debt discussed in Note 9, the Company entered into reverse interest rate lock agreements with several financial institutions which were not designated for hedge accounting. The Company entered into these agreements to hedge the variability in cash flows associated with $280 million of the $1.3 billion principal amount of debt that was retired in the first and second quarters of 2015. These agreements were settled during the first and second quarters of 2015, resulting in a gain of $3 million which was recognized in other income (expense), net.

11. STOCKHOLDERS’ EQUITY AND REDEEMABLE NONCONTROLLING INTEREST
Stockholders' Equity
Components of Comprehensive Income
The market value adjustments represent unrealized holding gains (losses) on available-for-sale securities, net of taxes. The net deferred loss on cash flow hedges represents deferred losses, net of taxes on the Company’s interest rate related derivative financial instruments designated as cash flow hedges, net of amounts reclassified to interest expense (see Note 10). For the three and nine months ended September 30, 2016 and 2015, the tax effects related to the market valuation adjustments and deferred losses were not material. Foreign currency translation adjustments are not adjusted for income taxes since they relate to indefinite investments in non-U.S. subsidiaries.
Dividend Program
During each of the quarters of 2016, the Company's Board of Directors declared a quarterly cash dividend of $0.40 per common share. During each of the quarters of 2015, the Company's Board of Directors declared a quarterly cash dividend of $0.38 per common share.
Share Repurchase Program
As of September 30, 2016, $532 million remained available under the Company’s share repurchase authorizations. The share repurchase authorization has no set expiration or termination date.
Share Repurchases
For the nine months ended September 30, 2016, the Company repurchased 5.7 million shares of its common stock for $440 million, which includes 3.1 million shares repurchased under an accelerated share repurchase agreement ("ASR") as follows:

(in millions, except per share data)
In May 2016, the Company entered into an ASR with a financial institution to repurchase $250 million of the Company's common stock as part of the Company's share repurchase program. The ASR was structured as a combination of two transactions: (1) a treasury stock repurchase; and (2) a forward contract, which permitted the Company to purchase shares immediately with the final purchase price of those shares determined by the volume weighted average price of the Company's common stock during the repurchase period, less a fixed discount. Under the ASR, the Company paid $250 million to the financial institution and received 3.1 million shares of common stock, resulting in a final price per share of $81.04. The Company initially received 2.8 million shares of its common stock during the second quarter of 2016 and received an additional 0.3 million shares upon completion of the ASR during the third quarter of 2016. As of June 30, 2016, the Company recorded this transaction as an increase to treasury stock for $212 million, and recorded the remaining $38 million as a decrease to additional paid-in capital. Upon completion of the ASR in the third quarter of 2016, the Company reclassified the $38 million to treasury stock from additional paid-in capital.
For the nine months ended September 30, 2015, the Company repurchased 2.4 million shares of its common stock for $174 million.
Shares Reissued from Treasury Stock
For the nine months ended September 30, 2016 and 2015, the Company reissued 1.4 million shares and 1.3 million shares, respectively, from treasury stock for employee benefit plans.
Redeemable Noncontrolling Interest
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. The subsidiary performs diagnostic information services in a defined territory within the state of Massachusetts. In 2015, the Company received consideration of $68 million. Since the redemption of the noncontrolling interest is outside of the Company's control, it has been presented outside of stockholders' equity at the greater of its carrying amount or its fair value. The Company will record changes in the fair value of the noncontrolling interest immediately as they occur. As of September 30, 2016, the redeemable noncontrolling interest was presented at its fair value.

Billing and Collection Agreement
In September 2016, the Company entered into a ten year agreement with a third party to outsource its billing and collection function. Services under the agreement commence during the fourth quarter of 2016. The agreement includes an annual fee, which is subject to adjustment based on certain changes in the Company's requisition volume and the achievement of various performance metrics.
Contingent Lease Obligations
The Company remains subject to contingent obligations under certain real estate leases 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 17 to the consolidated financial statements in the Company’s 2015 Annual Report on Form 10-K.
Agreement in Principle
In April 2015, a qui tam civil lawsuit entitled United States ex rel. Mayes v. Berkeley HeartLab, Inc., et al., filed in the U.S. District Court for the District of South Carolina, was unsealed. The complaint alleges that certain alleged business practices of the defendants violated the False Claims Act, and seeks monetary relief. The United States intervened as a plaintiff as to Berkeley HeartLab, Inc., a subsidiary of the Company and filed a complaint in intervention; the United States did not intervene as a plaintiff as to Quest Diagnostics Incorporated. The parties have reached an agreement in principle to resolve these matters, subject to further negotiation of terms and conditions and governmental sign-offs. In order to most efficiently and effectively finalize the settlement agreement, the parties have agreed to stay the filing of certain pleadings and their respective discovery requests associated with these matters.
Legal Matters
The Company is involved in various legal proceedings. Some of the proceedings against the Company involve claims that could be substantial in amount.
In addition to the matters described below, 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 legal actions may include lawsuits alleging negligence or other similar legal claims. 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, including, among other matters, operational matters, which may result in adverse judgments, settlements, fines, penalties, injunctions or other relief. The number of these reviews, investigations and proceedings has increased in recent years with regard to many firms in the healthcare services industry, including the Company.
In June 2010, the Company received a subpoena from the Florida Attorney General's Office seeking documents relating to the Company's pricing and billing practices as they relate to Florida’s Medicaid program. The Company cooperated with the requests. In November 2013, the State of Florida intervened as a plaintiff in a civil lawsuit, Florida ex rel. Hunter Laboratories LLC v. Quest Diagnostics Incorporated, et al., filed in Florida Circuit Court. The suit, originally filed by a competitor laboratory, alleges that the Company overcharged Florida’s Medicaid program. The Company's motion to dismiss the state's amended complaint was denied. The Company has filed a motion for summary judgment.
The federal or state governments may bring claims based on the Company's current practices, which it believes are lawful. In addition, certain federal and state statutes, including the qui tam provisions of the federal False Claims Act, allow private individuals to bring lawsuits against healthcare companies on behalf of government or private payers. The Company is aware of lawsuits, and from time to time has received subpoenas, related to billing practices based on the qui tam provisions of the Civil False Claims Act or other federal and state statutes, regulations or other laws. The Company understands that there

may be other pending qui tam claims brought by former employees or other "whistle blowers" as to which the Company cannot determine the extent of any potential liability.
Management cannot predict the outcome of such matters. Although management does not anticipate that the ultimate outcome of such matters will have a material adverse effect on the Company's financial condition, given the high degree of judgment involved in establishing loss estimates related to these types of matters, the outcome of such matters may be material to the Company's results of operations or cash flows in the period in which the impact of such matters is determined or paid.
These matters are in different stages. Some of these matters are in their early stages. Matters may involve responding to and cooperating with various government investigations and related subpoenas. As of September 30, 2016, the Company does not believe that material losses related to the legal matters described above are probable. While the Company believes that a reasonable possibility exists that losses may have been incurred related to the legal matters described above for which an accrual has not been recorded, based on the nature and status of these matters, potential losses, if any, cannot be estimated.
Reserves for Legal Matters
Reserves for legal matters, other than those described above, totaled $3 million and $9 million as of September 30, 2016 and December 31, 2015, 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 by considering actuarially determined losses based upon the Company's historical and projected loss experience. Such reserves totaled $119 million and $124 million as of September 30, 2016 and December 31, 2015, respectively. Management believes that established reserves and present insurance coverage are sufficient to cover currently estimated exposures. Management cannot predict the outcome of any claims made against the Company. Although management does not anticipate that the ultimate outcome of any such proceedings or claims will have a material adverse effect on the Company's financial condition, given the high degree of judgment involved in establishing accruals for loss estimates related to these types of matters, the outcome may be material to the Company's results of operations or cash flows in the period in which the impact of such claims is determined or paid.
14. BUSINESS SEGMENT INFORMATION
The Company's DIS business provides insights through clinical testing and related services to patients, physicians, hospitals, ACOs, IDNs, health plans, employers and others. The Company is the world's leading provider of diagnostic information services, which includes providing clinical testing services such as routine (including drugs-of-abuse) testing, advanced testing solutions (including gene-based and esoteric testing), and anatomic pathology services, as well as related services and insights. The DIS business accounted for greater than 90% of net revenues in 2016 and 2015.
All other operating segments include the Company's DS businesses, which consists of its risk assessment services, healthcare information technology, diagnostic products (prior to May 13, 2016), and clinical trials testing (prior to July 1, 2015) businesses. The Company's DS businesses offer a variety of solutions for life insurers, healthcare providers and others.
In addition to the sale of Focus Diagnostics (see Note 6), the Company wound down its Celera products business, which did not have a material impact on the Company's consolidated financial statements. As a result of these transactions, the Company has disposed of its diagnostics products business.
As of September 30, 2016, substantially all of the Company’s services are provided within the United States, and substantially all of the Company’s assets are located within the United States.

15. RELATED PARTIES
The Company's equity method investees primarily consist of its clinical trials central laboratory services joint venture and its diagnostic information services joint ventures, which are accounted for under the equity method of accounting. During each of the three months ended September 30, 2016 and 2015, the Company recognized net revenues of $8 million associated with diagnostic information services provided to its equity method investees. During the nine months ended September 30, 2016 and 2015, the Company recognized net revenues of $24 million and $23 million, respectively, associated with such services. As of September 30, 2016 and December 31, 2015, there was $9 million and $5 million, respectively, of accounts receivable from equity method investees related to such services.
During the three months ended September 30, 2016 and 2015, the Company recognized income of $4 million and $14 million, respectively, associated with the performance of certain corporate services, including transition services, for its equity method investees, classified within selling, general and administrative expenses.

accounts payable and accrued expenses as of September 30, 2016 and December 31, 2015 included $12 million and $9 million, respectively, due to equity method investees.
16. TAXES ON INCOME
For the three months ended September 30, 2016, the effective tax rate was impacted by a non-taxable gain on an escrow recovery associated with an acquisition and other discrete tax benefits. The effective tax rate for the three months ended September 30, 2015 was impacted by the higher tax rate associated with the $334 million gain on disposition of business as a result of the Company's contribution of its clinical trials testing business to Q 2 Solutions, the clinical trials joint venture with Quintiles Transnational Holdings Inc. ("Clinical Trials Contribution"), and other discrete tax benefits. In connection with the Clinical Trials Contribution, the Company recorded a $145 million deferred income tax liability. For details regarding the Company's 2015 dispositions, see Note 6 to the consolidated financial statements in the Company's 2015 Annual Report on Form 10-K.
For the nine months ended September 30, 2016, the effective tax rate was impacted by the higher tax rate associated with the sale of Focus Diagnostics (see Note 6), partially offset by a non-taxable gain on an escrow recovery associated with an acquisition and other discrete tax benefits. The effective tax rate for the nine months ended September 30, 2015 was impacted by the higher tax rate associated with the Clinical Trials Contribution and other discrete tax benefits.

Item 2. | Management’s Discussion and Analysis of Financial Condition and Results of Operations

Our Company
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 insights through clinical testing and related services to patients, physicians, hospitals, accountable care organizations ("ACOs"), integrated delivery networks ("IDNs"), health plans, employers and others. We offer the broadest access in the United States to diagnostic information services through our nationwide network of laboratories, Company-owned patient service centers and phlebotomists in physician offices. We are the world's leading provider of diagnostic information services, which includes providing clinical testing services such as routine (including drugs-of-abuse) testing, advanced testing solutions (including gene-based and esoteric testing), and anatomic pathology services, as well as related services and insights. We provide interpretive consultation with one of the largest medical and scientific staffs in the industry. Our DIS business makes up over 90% of our consolidated net revenues.
In our Diagnostic Solutions ("DS") businesses, which represents the balance of our consolidated net revenues, we offer a variety of solutions to insurers and healthcare providers. We are the leading provider of risk assessment services for the life insurance industry. In addition, we offer healthcare organizations and clinicians robust information technology solutions. Prior to the sale of our Focus Diagnostics products business ("Focus Sale") on May 13, 2016 (see "Sale of Focus Diagnostics Products" and Note 6 to the interim unaudited consolidated financial statements for further details) our diagnostics products business manufactured and marketed diagnostic products. Prior to the contribution of our clinical trials testing business to the Q 2 Solutions joint venture on July 1, 2015 ("Clinical Trials Contribution"), our clinical trials testing business was a leading provider of central laboratory testing for clinical trials.
Third Quarter Highlights
Highlights of our results of operations for the third quarter of 2016 are as follows:

• | Our total net revenues of $1.89 billion were 0.3% above the prior year period. The Focus Sale and winding down of our Celera products business ("Celera Products") negatively impacted revenue growth by 1.8%.

• | DIS revenues of $1.8 billion increased by 2.1% compared to the prior year period. DIS volume, measured by the number of requisitions, increased 2.0% compared to the prior year period. Revenue per requisition was flat compared to the prior year period.

• | DS revenues of $85 million were 27.1% below the prior year period due to the Focus Sale and winding down of Celera Products.

• | Net income attributable to Quest Diagnostics' stockholders was $192 million, or $1.34 per diluted share.

Pursuant to the federal Protecting Access to Medicare Act of 2014 ("PAMA"), the Centers for Medicare and Medicaid Services will revise reimbursement schedules for clinical laboratory testing services provided under Medicare, which is targeted for implementation in 2018. We continue to evaluate the impact of this final rule. While we cannot determine the impact until we see the final pricing data, we continue to believe that the impact will be manageable.
Five-point Strategy
Our five-point strategy is described in detail in "Item 1. Business" in our 2015 Annual Report on Form 10-K. During the nine months ended September 30, 2016, we continued to make progress on the execution of our five-point strategy as follows:
Acquisition of the Outreach Laboratory Service Business of Clinical Laboratory Partners
On February 29, 2016, we completed the acquisition of the outreach laboratory service business of Clinical Laboratory Partners, LLC ("CLP"), a wholly-owned subsidiary of Hartford HealthCare Corporation, in an all-cash transaction for $135 million. The acquired outreach laboratory service business of CLP is included in our DIS business.
For details regarding our acquisitions, see Note 5 to the interim unaudited consolidated financial statements and Note 5 to the consolidated financial statements in our 2015 Annual Report on Form 10-K.

Sale of Focus Diagnostics Products
In March 2016, we signed a definitive agreement to sell the assets of our non-core Focus Diagnostics products business ("Focus Diagnostics") to DiaSorin S.p.A. On May 13, 2016, we completed the sale of Focus Diagnostics for $300 million in cash, or $293 million net of transaction costs and working capital adjustments, which includes $25 million of proceeds held in escrow. For the nine months ended September 30, 2016, we recorded a $118 million pre-tax gain on disposition of business. We also recorded income tax expense of $84 million, consisting of $91 million of current income tax expense and a deferred income tax benefit of $7 million.
As a result of this transaction, we have disposed of our remaining diagnostics products business as part of our efforts to refocus on diagnostic information services.
The proceeds from the Focus Sale were used to fund the repurchase of shares under the $250 million accelerated share repurchase agreement entered into in May 2016.
For further details regarding our dispositions and assets held for sale, see Note 6 to the interim unaudited consolidated financial statements and Note 6 to the consolidated financial statements in our 2015 Annual Report on Form 10-K.
Accelerated Share Repurchase Agreement ("ASR")
In May 2016, we entered into an ASR with a financial institution to repurchase $250 million of our common stock as part of our share repurchase program. Under the ASR, we paid $250 million to the financial institution and received 3.1 million shares of our common stock, resulting in a final price per share of $81.04. We initially received 2.8 million shares of our common stock during the second quarter of 2016 and received an additional 0.3 million shares upon completion of the ASR during the third quarter of 2016.
For further details regarding the ASR and repurchases of our common stock, see Note 11 to the interim unaudited consolidated financial statements and "Liquidity and Capital Resources: Share Repurchases".
Retirement of Debt
In March 2016, we completed a cash tender offer ("2016 Tender Offer") to purchase up to $200 million aggregate principal amount of our 6.95% Senior Notes due July 2037 ("Senior Notes due 2037") and 5.75% Senior Notes due January 2040 ("Senior Notes due 2040"). We purchased $73 million of our Senior Notes due 2037 and $127 million of our Senior Notes due 2040 using a combination of cash on-hand and borrowing under our secured receivables credit facility. The retirement of debt is expected to reduce future interest expense. In connection with this transaction, we recorded a pre-tax loss on retirement of debt of $48 million, principally comprised of premiums paid, for the nine months ended September 30, 2016.
For further details regarding our debt and related transactions, see Note 9 to the interim unaudited consolidated financial statements and Note 13 to the consolidated financial statements in our 2015 Annual Report on Form 10-K.
Senior Notes Offering
In May 2016, the Company completed a $500 million senior notes offering (the “2016 Senior Notes”), consisting of $500 million in aggregate principal of 3.45% senior notes due June 2026, issued at a discount of $1 million. The net proceeds from the 2016 Senior Notes were used to repay outstanding indebtedness under our senior unsecured revolving credit facility and our secured receivables credit facility and for general corporate purposes.
For further details regarding our the 2016 Senior Notes and our debt, see Note 9 to the interim unaudited consolidated financial statements.
Invigorate Program
We are engaged in a multi-year program called Invigorate, which is designed to reduce our cost structure. We delivered more than $700 million in run-rate savings as we exited 2014. In November 2014, we announced our goal to deliver an additional $600 million in run-rate savings as we exit 2017. Achieving this goal would bring the total savings from the Invigorate program to $1.3 billion in run-rate savings, compared to 2011. In 2015, we delivered realized savings of more than $200 million and believe we are on track to achieve our $1.3 billion run-rate savings goal by the end of 2017.
28

Table of Contents
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; service excellence; lab excellence; and billing excellence. In addition to these programs, we identified new key opportunities to change how we operate in order to meet our goal of delivering the additional $600 million in run-rate savings as we exit 2017. These new key opportunities include: standardizing our processes, information technology systems, equipment and data; enhancing electronic enabling services; and enhancing reimbursement for work we perform. We believe that our efforts to standardize our information technology systems, equipment and data also will foster our efforts to restore 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.
In January 2015, we adopted a course of action related to this multi-year program. We developed a high-level estimate of the total pre-tax charges expected to be incurred in 2015 through 2017 in connection with the course of action for the program: $300 million. During 2015, we incurred $89 million of charges in connection with the course of action. In February 2016, we developed high-level estimates of the pre-tax charges expected to be incurred in connection with the course of action for 2016 totaling $80 million to $100 million, consisting of up to $10 million of employee separation costs and $80 million to $90 million of systems conversion and integration costs. During the third quarter of 2016, we updated our estimates of the pre-tax charges expected to be incurred in connection with the course of action for 2016 to $50 million to $65 million, consisting of $10 to $15 million of employee separation costs and $40 million to $50 million of systems conversion and integration costs. For the nine months ended September 30, 2016, we incurred $43 million in connection with the course of action. As detailed plans to implement the course of action are approved and executed, it will result in charges to earnings. Principally all of the total estimated pre-tax charges expected to be incurred in 2016 are anticipated to result in cash expenditures. The actual charges incurred in connection with the course of action in 2016 could be materially different from these estimates.
From 2012 through 2014, the cumulative charges incurred in connection with the Invigorate program were $266 million, including $178 million of cumulative pre-tax employee separation costs and other restructuring related costs. From the beginning of 2015 through September 30, 2016, the cumulative charges incurred in connection with the Invigorate program were $132 million, including approximately $48 million of cumulative pre-tax employee separation costs and other restructuring related costs.
For further details of the Invigorate program and associated costs, see Note 4 to the interim unaudited consolidated financial statements.

cash asset impairment charges associated with Celera Products and costs incurred related to certain legal matters, partially offset by a gain of $13 million associated with a decrease in the fair value of the contingent consideration accrual associated with our Summit Health, Inc. ("Summit Health") acquisition.
Net Revenues
Net revenues for the three months ended September 30, 2016 increased by 0.3% compared to the prior year period. The Focus Sale and winding down of Celera Products negatively impacted revenue growth by 1.8%.
DIS revenues for the three months ended September 30, 2016 increased by 2.1% compared to the prior year period. Our performance reflects expanding hospital system relationships. Organic growth and acquisitions contributed approximately 1.0% and 1.1%, respectively, to DIS revenue growth. DIS volume, measured by the number of requisitions, increased 2.0%, with organic growth and acquisitions each contributing approximately 1.0% to DIS volume growth. Revenue per requisition was flat compared to the prior year period. Revenue per requisition benefited from favorable test mix, which was essentially offset by unit pricing pressure of approximately 0.5% and lower revenue per requisition associated with our professional lab services engagements.
For the three months ended September 30, 2016, combined revenues in our DS businesses decreased by 27.1% compared to the prior year period due to the Focus Sale and winding down of Celera Products.
Net revenues for the nine months ended September 30, 2016 increased by 0.2% compared to the prior year period. The Clinical Trials Contribution, Focus Sale and winding down of Celera Products negatively impacted revenue growth by 2.6%.
DIS revenues for the nine months ended September 30, 2016 increased by 2.7% compared to the prior year period. Our performance reflects continued focus on advanced testing solutions and expanding hospital system relationships. Organic growth and acquisitions contributed approximately 2.0% and 0.7%, respectively, to DIS revenue growth. DIS volume, measured by the number of requisitions, increased 2.2%, with organic growth contributing approximately 1.4% to DIS volume growth. Acquisitions contributed approximately 0.8% to DIS volume growth. Revenue per requisition increased 0.4% compared to the prior year period. Revenue per requisition benefited from favorable test mix, which was partially offset by pricing pressure of less than 1% and lower revenue per requisition associated with our professional lab services engagements.
For the nine months ended September 30, 2016, combined revenues in our DS businesses decreased by 30.7% compared to the prior year period due to the Clinical Trials Contribution, Focus Sale and winding down of Celera Products.
Cost of Services
Cost of services consists principally of costs for obtaining, transporting and testing specimens as well as facility costs used for the delivery of our services.
Cost of services decreased $5 million for the three months ended September 30, 2016 compared to the prior year period. The decrease was primarily driven by lower costs as a result of the Focus Sale and winding down of Celera Products, net cost reductions under the Invigorate program, lower restructuring and integration charges and lower depreciation expense, partially offset by higher compensation and benefits and higher costs related to our recent acquisitions.
Cost of services decreased $51 million for the nine months ended September 30, 2016 compared to the prior year period. The decrease was primarily driven by lower costs as a result of the Clinical Trials Contribution, Focus Sale and winding down of Celera Products, net cost reductions under the Invigorate program, lower restructuring and integration charges and lower depreciation expense, partially offset by higher compensation and benefits and higher costs related to our recent acquisitions.
For further details regarding the impact of the change in estimated useful lives of our property, plant and equipment on depreciation expense, see Note 2 to the interim unaudited consolidated financial statements.
Selling, General and Administrative Expenses ("SG&A")
SG&A consist principally of the costs associated with our sales and marketing efforts, billing operations, bad debt expense and general management and administrative support as well as administrative facility costs.
33

Table of Contents
SG&A for the three months months ended September 30, 2016 increased $7 million compared to the prior year period. The increases in SG&A were primarily driven by higher compensation and benefits, partially offset by lower costs as a result of the Focus Sale and winding down of Celera Products, net cost reductions under the Invigorate program and lower depreciation expense.
SG&A for the nine months months ended September 30, 2016 increased $31 million compared to the prior year period. The increases in SG&A were primarily driven by higher compensation and benefits and higher bad debt expense, partially offset by lower costs as a result of the Clinical Trials Contribution, Focus Sale and winding down of Celera Products, net cost reductions under the Invigorate program and lower depreciation expense.
The increase in bad debt expense as a percentage of net revenues for the nine months ended September 30, 2016, compared to the prior year period, was primarily a result of our recent dispositions which had lower bad debt rates than our DIS business and increased patient responsibility associated with coinsurance and deductible requirements.
Gain on Disposition of Business
For the nine months ended September 30, 2016, the gain on disposition of business was a result of the Focus Sale. The gain on disposition of business for the three and nine months ended September 30, 2015 was a result of the Clinical Trials Contribution.
Other Operating Income, net
Other operating income, net includes miscellaneous income and expense items related to operating activities.
For the three and nine months ended September 30, 2016, other operating income, net principally consists of a gain on an escrow recovery associated with an acquisition.
For the nine months ended September 30, 2015, other operating income, net includes non-cash asset impairment charges primarily associated with Celera Products, essentially offset by a gain of $13 million associated with a decrease in the fair value of the contingent consideration accrual associated with our Summit Health acquisition.
Interest Expense, net
For the three months ended September 30, 2016, interest expense, net increased by $2 million compared to the prior year period. Interest expense, net for the nine months ended September 30, 2016 decreased by $10 million, compared to the prior year period, primarily a result of lower interest rates as a result of the debt refinancing in 2015 and to a lesser extent the 2016 refinancing.
Other Income (Expense), net
Other income (expense), net represents miscellaneous income and expense items related to non-operating activities, such as gains and losses associated with investments, other non-operating assets and early retirement of debt.
For the nine months ended September 30, 2016, other income (expense), net includes the loss on retirement of debt of $48 million associated with the 2016 Tender Offer and non-cash asset impairment charges associated with certain investments of $7 million.
For the nine months ended September 30, 2015, other income (expense), net includes the loss on retirement of debt of $144 million associated with the 2015 Tender Offer and 2015 Redemption.
Income Tax Expense
The $144 million decrease in income tax expense for the three months ended September 30, 2016, compared to the prior year period, was primarily a result of $145 million of deferred income tax expense associated with the gain on the Clinical Trials Contribution in the prior year period.
34

Table of Contents
The decrease in the effective tax rate for the three months ended September 30, 2016, compared to the prior year period, was primarily a result of the higher tax rate associated with the Clinical Trials Contribution in the prior year period, a non-taxable gain on an escrow recovery in the third quarter of 2016 associated with an acquisition and other discrete tax benefits.
Income tax expense for the nine months ended September 30, 2016 decreased by $14 million compared to the prior year period. For nine months ended September 30, 2016, income tax expense includes $84 million, consisting of $91 million of current income taxes payable and a deferred income tax benefit of $7 million, associated with the gain on the Focus Sale. The income tax expense resulted in an effective tax rate of 71.4%, which was significantly in excess of the statutory tax rate primarily due to a lower tax basis in the assets sold, specifically the goodwill associated with the disposition.
For the nine months ended September 30, 2015, income tax expense includes $145 million of deferred income tax expense associated with the gain on the Clinical Trials Contribution, which was partially offset by income tax benefits associated with the loss on retirement of debt associated with the 2015 Tender Offer and 2015 Redemption.
The effective tax rate for the nine months ended September 30, 2016, compared to the prior year period, increased primarily as a result of the higher tax rate associated with the Focus Sale, partially offset by the tax rate associated with the Clinical Trials Contribution in the prior year period, a non-taxable gain on an escrow recovery in the third quarter of 2016 associated with an acquisition and other discrete tax benefits.
Quantitative and Qualitative Disclosures About Market Risk
We address our exposure to market risks, principally the market risk of changes in interest rates, through a controlled program of risk management that includes the use of derivative financial instruments. We do not hold or issue derivative financial instruments for speculative purposes. We seek to mitigate the variability in cash outflows that result from changes in interest rates by maintaining a balanced mix of fixed-rate and variable-rate debt obligations. In order to achieve this objective, we have entered into interest rate swaps. Interest rate swaps involve the periodic exchange of payments without the exchange of underlying principal or notional amounts. Net settlements are recognized as an adjustment to interest expense. We believe that our exposures to foreign exchange impacts and changes in commodity prices are not material to our consolidated financial condition or results of operations.
At September 30, 2016 and December 31, 2015, the fair value of our debt was estimated at approximately $4.1 billion and $3.7 billion, respectively, using quoted prices in active markets and yields for the same or similar types of borrowings, taking into account the underlying terms of the debt instruments. At September 30, 2016 and December 31, 2015, the estimated fair value exceeded the carrying value of the debt by $245 million and $82 million, respectively. A hypothetical 10% increase in interest rates (representing 38 basis points at September 30, 2016 and 39 basis points at December 31, 2015) would potentially reduce the estimated fair value of our debt by approximately $91 million and $112 million at September 30, 2016 and December 31, 2015, 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 rates that are intended to approximate commercial paper rates for highly rated issuers. Interest on our senior unsecured revolving credit facility is subject to a pricing schedule that can fluctuate based on changes in our credit ratings. As such, our borrowing cost under this credit arrangement will be subject to both fluctuations in interest rates and changes in our credit ratings. At September 30, 2016, the borrowing rates under these debt instruments were: for our secured receivables credit facility, commercial paper rates for highly rated issuers plus 0.66%; and for our senior unsecured revolving credit facility, LIBOR plus 1.125%. At September 30, 2016, the weighted average LIBOR was 0.5%. As of September 30, 2016, there were no borrowings outstanding under our $600 million secured receivables credit facility and no borrowings outstanding under our $750 million senior unsecured revolving credit facility.
As of December 31, 2015, the Company had entered into various fixed-to-variable interest rate swap agreements with an aggregate notional amount of $1.2 billion and variable interest rates ranging from one-month LIBOR plus 1.4% to one-month LIBOR plus 3.6%. In July 2016, the Company monetized the value of these interest rate swap assets by terminating the hedging instruments. The proceeds, including accrued interest through the date of termination, were $60 million, which consisted of the asset values of $54 million and accrued interest of $6 million. The remaining basis adjustment on the respective debt obligation of $54 million will be amortized as a reduction of interest expense over the remaining terms of the hedged debt instrument. Immediately after the termination of these interest rate swaps, the Company entered into new fixed-to-variable interest rate swap agreements. The new interest rate swaps have an aggregate notional amount of $1.2 billion and variable interest rates ranging from one-month LIBOR plus 2.2% and one-month LIBOR plus 3.0%. These derivative financial
35

Table of Contents
instruments are accounted for as fair value hedges of a portion of the Senior Notes due 2024, the Senior Notes due 2025 and a portion of the Senior Notes due 2026.
The notional amount of fixed-to-variable interest rate swaps outstanding at both September 30, 2016 and December 31, 2015 was $1.2 billion. The aggregate fair value of the fixed-to-variable interest rate swaps is $5 million, in a liability position, at September 30, 2016. There were no forward starting interest rate swaps outstanding at September 30, 2016 and December 31, 2015.
Based on our net exposure to interest rate changes, a hypothetical 10% change in interest rates on our variable rate indebtedness (representing 5 basis points) would not impact annual interest expense materially, assuming no changes to the debt outstanding at September 30, 2016. A hypothetical 10% change in the forward one-month LIBOR curve (representing a 12 basis point change in the weighted average yield) would potentially change the fair value of our derivative liabilities by $20 million.
For further details regarding our outstanding debt, see Note 9 to the interim unaudited consolidated financial statements and Note 13 to the consolidated financial statements included in our 2015 Annual Report on Form 10-K. For details regarding our financial instruments and hedging activities, see Note 10 to the interim unaudited consolidated financial statements and Note 14 to the consolidated financial statements included in our 2015 Annual Report on Form 10-K.
Risk Associated with Investment Portfolio
Our investment portfolio includes equity investments comprised primarily of strategic equity holdings in privately and publicly held companies. These securities are exposed to price fluctuations and are generally concentrated in the life sciences industry. The carrying value of our equity investments (excluding investments accounted for under the equity method) was $11 million at September 30, 2016.
We regularly evaluate the fair value measurements of our equity investments to determine if losses in value are other than temporary and if an impairment loss has been incurred. The evaluation considers whether the security has the ability to recover and, if so, the estimated recovery period. Other factors that are considered in this evaluation include the amount of the other-than-temporary decline and its duration, the issuer’s financial condition and short-term prospects, and whether the market decline was caused by overall economic conditions or conditions specific to the individual security.
We do not hedge our equity price risk. The impact of an adverse movement in equity prices on our holdings in privately held companies cannot be easily quantified, as our ability to realize returns on investments depends on, among other things, the enterprises’ ability to raise additional capital or derive cash inflows from continuing operations or through liquidity events such as initial public offerings, mergers or private sales.

Cash and Cash Equivalents
Cash and cash equivalents consist of cash and highly liquid short-term investments. Cash and cash equivalents at September 30, 2016 totaled $406 million, compared to $133 million as of December 31, 2015.
Cash Flows from Operating Activities
Net cash provided by operating activities for the nine months ended September 30, 2016 was $765 million, compared to $549 million for the nine months ended September 30, 2015. This $216 million increase in net cash provided by operating activities was primarily a result of:
36

Table of Contents

• | a $99 million decrease in pre-tax cash charges ($69 million after the related cash tax benefits) associated with the 2016 Tender Offer as compared to the 2015 Tender Offer and 2015 Redemption;

• | an additional payroll cycle in the first quarter of 2015;

• | $54 million of proceeds received in the third quarter of 2016 from the termination of interest rate swap agreements; and

• | a $35 million decrease in interest paid.

These increases in net cash provided by operation activities were partially offset by a $13 million increase in income taxes paid. Income taxes paid for the nine months ended September 30, 2016 includes a $68 million income tax payment in the third quarter of 2016 related to the Focus Sale. Income taxes paid for the nine months ended September 30, 2015 includes a $45 million income tax payment in the third quarter of 2015 associated with certain tax contingencies.
Days sales outstanding, a measure of billing and collection efficiency, was 46 days at September 30, 2016, 47 days at December 31, 2015 and 44 days at September 30, 2015.
Cash Flows from Investing Activities
Net cash used in investing activities for the nine months ended September 30, 2016 was $45 million, compared to $237 million for the nine months ended September 30, 2015. This $192 million decrease in net cash used in investing activities was a primarily a result of:

• | a $270 million increase in proceeds from the disposition of businesses, principally related to the Focus Sale; and

• | a $37 million decrease in investment in equity method investee, related to cash included in our contribution to Q 2 Solutions in 2015.

These decreases in net cash used in investing activities were partially offset by a $98 million increase in cash paid for business acquisitions in 2016, principally a result of the CLP acquisition in 2016.
Cash Flows from Financing Activities
Net cash used in financing activities for the nine months ended September 30, 2016 was $447 million, compared to $381 million for the nine months ended September 30, 2015. This $66 million increase in net cash used in financing activities was primarily a result of:

• | a $266 million increase in repurchases of our common stock (see "Share Repurchases" for further details); and

• | a $51 million decrease in proceeds from the sale of a noncontrolling interest in a subsidiary, as a result of the sale of a noncontrolling interest in a subsidiary to UMass in 2015.

These increases in net cash used in financing activities were partially offset by:

• | a $168 million net increase in net borrowings (proceeds from borrowings less repayments of debt);

• | a $51 million decrease in payment of deferred acquisition consideration, principally a result of a payment to UMass Memorial Medical Center ("UMass") in 2015 related to the business acquisition in 2013; and

• | a $44 million decrease in other financing activities, net.

In 2016, we completed the issuance of the 2016 Senior Notes and the 2016 Tender Offer and repaid the remaining $150 million outstanding under the 3.20% Senior Notes due April 2016. In addition, both cumulative borrowings and repayments under our secured receivables credit facility totaled $1.2 billion as of September 30, 2016. Both cumulative borrowings and repayments under our senior unsecured revolving credit facility totaled $155 million as of September 30, 2016.
The CLP acquisition and 2016 Tender Offer were funded using a combination of cash on-hand and borrowings under our secured receivables credit facility.
In 2015, we completed the $1.2 billion senior notes offering in March 2015, the 2015 Tender Offer and the 2015 Redemption. In addition, cumulative borrowings and repayments under our secured receivables credit facility totaled $1.0 billion and $955 million, respectively, as of September 30, 2015.

Dividends
During each of the quarters of 2016, our Board of Directors declared a quarterly cash dividend of $0.40 per common share. During each of the quarters of 2015, our Board of Directors declared a quarterly cash dividend of $0.38 per common share. We expect to fund future dividend payments with cash flows from operations and do not expect the dividend to have a material impact on our ability to finance future growth.
Share Repurchases
As of September 30, 2016, $532 million remained available under our share repurchase authorizations. The share repurchase authorization has no set expiration or termination date.
For the nine months ended September 30, 2016, we repurchased 5.7 million shares of our common stock for $440 million, which includes 3.1 million shares repurchased under the May 2016 ASR for $250 million (see "Five-point Strategy: Accelerated Share Repurchase Agreement" for further details).
For the nine months ended September 30, 2015, we repurchased 2.4 million shares of our common stock for $174 million.
Contractual Obligations and Commitments
The following table summarizes certain of our contractual obligations as of September 30, 2016:

|  | Payments due by period
|  | (in millions)
Contractual Obligations |  | Total |  | Remainder of 2016 |  | 1-3 years |  | 3-5 years |  | After 5 years
Outstanding debt |  | $ | 3,775 |  |  | $ | — |  |  | $ | — |  |  | $ | 1,100 |  |  | $ | 2,675 |
Capital lease obligations |  | 15 |  |  | 2 |  |  | 10 |  |  | 3 |  |  | — |
Interest payments on outstanding debt |  | 1,635 |  |  | 30 |  |  | 297 |  |  | 269 |  |  | 1,039 |
Operating leases |  | 711 |  |  | 53 |  |  | 301 |  |  | 155 |  |  | 202 |
Purchase obligations |  | 2,153 |  |  | 52 |  |  | 538 |  |  | 432 |  |  | 1,131 |

Total contractual obligations |  | $ | 8,293 |  |  | $ | 139 |  |  | $ | 1,148 |  |  | $ | 1,959 |  |  | $ | 5,047 |

Interest payments on our outstanding debt have been calculated after giving effect to our interest rate swap agreements, using the interest rates as of September 30, 2016 applied to the September 30, 2016 balances, which are assumed to remain outstanding through their maturity dates.
A full description of the terms of our indebtedness and related debt service requirements and our future payments under certain of our contractual obligations is contained in Note 13 to the consolidated financial statements in our 2015 Annual Report on Form 10-K and Note 9 to the interim unaudited consolidated financial statements. A full discussion and analysis regarding our minimum rental commitments under noncancelable operating leases and noncancelable commitments to purchase services or products is contained in Note 17 to the consolidated financial statements in our 2015 Annual Report on Form 10-K. A discussion regarding our agreement to outsource our billing and collection function, which is included in purchase obligations in the table above, is contained in Note 13 to the interim unaudited consolidated financial statements. A full discussion and analysis regarding our acquisition of Steward Health Care Systems, LLC's laboratory outreach business and the related merger consideration obligation is contained in Note 5 to the consolidated financial statements in our 2015 Annual Report on Form 10-K.
As of September 30, 2016, our total liabilities associated with unrecognized tax benefits were approximately $95 million, which were excluded from the table above. We expect that these liabilities may decrease by less than $5 million within the next twelve months, primarily as a result of payments, settlements 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. Additionally, it is reasonably possible that within the next 12 months, as result of ongoing negotiations with tax
38

Table of Contents
authorities and the expiration of statutes of limitations, our total liabilities associated with unrecognized tax benefits will further decrease and beneficially impact the effective tax rate for continuing operations. However, due to the inherent uncertainty of the negotiations and the resulting outcomes, we are not able to estimate the effective tax rate impact at this time. See Note 8 to the consolidated financial statements in our 2015 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 September 30, 2016, the fair value of the redeemable noncontrolling interest on the interim unaudited consolidated balance sheet was $76 million, which was excluded from the table above. Since the redemption of the noncontrolling interest is outside of our control, we cannot make a reasonably reliable estimate of the timing of the future payment, if any, of the redeemable noncontrolling interest. For further details regarding the redeemable noncontrolling interest, see Note 11 to the interim unaudited consolidated financial statements.
Our credit agreements contain various covenants and conditions, including the maintenance of certain financial ratios, that could impact our ability to, among other things, incur additional indebtedness. As of September 30, 2016, we were in compliance with the various financial covenants included in our credit agreements and we do not expect these covenants to adversely impact our ability to execute our growth strategy or conduct normal business operations.
Equity Method Investees
Our equity method investees primarily consist of our clinical trials central laboratory services joint venture and our diagnostic information services joint ventures, which are accounted for under the equity method of accounting. We believe that our transactions with our equity method investees are conducted at arm’s length, reflecting current market conditions and pricing. Our investment in equity method investees equals less than 5% of our consolidated total assets. Our proportionate share of income before income taxes associated with our equity method investees equals less than 5% of our consolidated income before income taxes and equity in earnings of equity method investees. We have no material unconditional obligations or guarantees to, or in support of, our equity method investees and their operations.
For further details regarding related party transactions with our equity method investees, see Note 15 to the interim unaudited consolidated financial statements.
Requirements and Capital Resources
We estimate that we will invest approximately $250 million during 2016 for capital expenditures, to support and grow our existing operations, principally related to investments in information technology, laboratory equipment and facilities, including specific initiatives associated with our Invigorate and other programs.
As of September 30, 2016, $1.3 billion of borrowing capacity was available under our existing credit facilities consisting of $532 million available under our secured receivables credit facility and $750 million available under our senior unsecured revolving credit facility.
We believe the borrowing capacity under the credit facilities described above continues to be available to us. Should one or several banks no longer participate in either of our credit facilities, we would not expect it to impact our ability to fund operations. We expect that we will be able to replace our existing credit facilities with alternative arrangements prior to their expiration.
At September 30, 2016, approximately 14% of our $406 million of consolidated cash and cash equivalents were held outside of the United States. These funds are considered indefinitely reinvested to be used to expand operations either organically or through acquisitions outside the United States. Further, our current plans do not demonstrate a need to repatriate foreign funds in order to fund U.S. operations. If the foreign cash and cash items are needed for operations in the United States, or we otherwise elect to repatriate the funds, we may be required to accrue and pay United States taxes on a significant portion of these amounts.
We believe that our cash and cash equivalents and cash from operations, together with our borrowing capacity under our credit facilities, will provide sufficient financial flexibility to fund seasonal and other working capital requirements, capital expenditures, debt service requirements and other obligations, cash dividends on common shares, share repurchases and additional growth opportunities for the foreseeable future. We believe that our credit profile should provide us with access to
39

additional financing to refinance upcoming debt maturities and, if necessary, to fund growth opportunities that cannot be funded from existing sources.
Impact of New Accounting Standards
The impacts of recent accounting pronouncements not yet effective on our consolidated financial statements are discussed in Note 2 to the interim unaudited consolidated financial statements.
Forward-Looking Statements
Some statements and disclosures in this document are forward-looking statements. Forward-looking statements include all statements that do not relate solely to historical or current facts and can be identified by the use of words such as “may,” “believe,” “will,” “expect,” “project,” “estimate,” “anticipate,” “plan” or “continue.” These forward-looking statements are based on our current plans and expectations and are subject to a number of risks and uncertainties that could cause our plans and expectations, including actual results, to differ materially from the forward-looking statements. Risks and uncertainties that may affect our future results include, but are not limited to, adverse results from pending or future government investigations, lawsuits or private actions, the competitive environment, changes in government regulations, changing relationships with customers, payers, suppliers and strategic partners and other factors discussed in our most recently filed Annual Report on Form 10-K and subsequently filed Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, including those discussed in the “Business,” “Risk Factors,” “Cautionary Factors that May Affect Future Results” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of those reports.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
See Item 2. "Management's Discussion and Analysis of Financial Condition and Results of Operations."
Item 4. Controls and Procedures
Under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we have evaluated the effectiveness of our disclosure controls and procedures (as defined under Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended). Based upon that evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this quarterly report.
During the third quarter of 2016, there were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended) that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
