ZOETIS INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. Organization

Zoetis Inc. (including its subsidiaries, collectively, Zoetis, the company, we, us or our) is a global leader in the discovery, development, manufacture and commercialization of animal health medicines, vaccines and diagnostic products with a focus on both livestock and companion animals. We organize and operate our business in two geographic regions: the United States (U.S.) and International.

We directly market our products in approximately 45 countries across North America, Europe, Africa, Asia, Australia and South America. Our products are sold in more than 100 countries, including developed markets and emerging markets. We have a diversified business, marketing products across eight core species: cattle, swine, poultry, fish and sheep (collectively, livestock) and dogs, cats and horses (collectively, companion animals); and within seven major product categories: vaccines, anti-infectives, parasiticides, dermatology, other pharmaceuticals, medicated feed additives and animal health diagnostics.

2. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements were prepared following the requirements of the Securities and Exchange Commission (SEC) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by accounting principles generally accepted in the United States of America (U.S. GAAP) can be condensed or omitted. Balance sheet amounts and operating results for subsidiaries operating outside the U.S. are as of and for the nine-month periods ended August 31, 2020 and August 31, 2019.

Revenue, expenses, assets and liabilities can vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be representative of those for the full year.

Certain reclassifications of prior year information have been made to conform to the current year's presentation.

We are responsible for the unaudited condensed consolidated financial statements included in this Form 10-Q. The condensed consolidated financial statements include all normal and recurring adjustments that are considered necessary for the fair presentation of our financial position and operating results. The information included in this interim report should be read in conjunction with the financial statements and accompanying notes included in our 2019 Annual Report on Form 10-K.

3. Accounting Standards

Recently Adopted Accounting Standards

In August 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Topic 350-40), an accounting standards update which expands the scope of costs associated with cloud computing arrangements that must be capitalized. Under the new guidance, costs associated with implementing a cloud computing arrangement that is a service contract must be capitalized and expensed over the term of the hosting arrangement. We adopted this guidance as of January 1, 2020, the required effective date, on a prospective basis. The adoption did not have a significant impact on our consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments (Topic 326), an accounting standards update which requires an entity to measure and recognize expected credit losses for certain financial instruments, including trade receivables, as an allowance that reflects the entity's current estimate of credit losses expected to be incurred. For available-for-sale debt securities with unrealized losses, the standard requires allowances to be recorded instead of reducing the amortized cost of the investment. We adopted this guidance as of January 1, 2020, the required effective date, on a prospective basis. The adoption did not have a significant impact on our consolidated financial statements.

Recently Issued Accounting Standards

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The new guidance provides temporary optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued because of reference rate reform. Adoption of the provisions of ASU 2020-04 is optional and effective as of March 12, 2020, but is only available through December 31, 2022. We are currently evaluating the impact that the new guidance will have on our consolidated financial statements and related disclosures, as well as the timing of the potential adoption.

4. Revenue

A. Revenue from Product Sales

We offer a diversified portfolio of products which allows us to capitalize on local and regional customer needs. Generally, our products are promoted to veterinarians and livestock producers by our sales organization which includes sales representatives and technical and veterinary operations specialists, and then sold directly by us or through distributors, retailers and e-commerce outlets. The depth of our product portfolio enables us to address the varying needs of customers in different species and geographies. Many of our top selling product lines are distributed

7 |

across both of our operating segments, leveraging our research and development (R&D) operations and manufacturing and supply chain network.

Over the course of our history, we have focused on developing a diverse portfolio of animal health products, including medicines, vaccines and diagnostics, complemented by biodevices, genetic tests and a range of services. We refer to a single product in all brands, or its dosage forms for all species, as a product line. We have approximately 300 comprehensive product lines, including products for both livestock and companion animals across each of our major product categories.

In the fourth quarter of 2019, the company modified the list of major product categories to include a category for dermatology products, which was previously included within other pharmaceutical products. The prior period presentation has been revised to reflect the new product categories.

Our major product categories are:

•vaccines: biological preparations that help prevent diseases of the respiratory, gastrointestinal and reproductive tracts or induce a specific immune response;

•anti-infectives: products that prevent, kill or slow the growth of bacteria, fungi or protozoa;

•parasiticides: products that prevent or eliminate external and internal parasites such as fleas, ticks and worms;

•dermatology products: products that relieve itch associated with allergic conditions and atopic dermatitis;

•other pharmaceutical products: pain and sedation, antiemetic, reproductive, and oncology products;

•medicated feed additives: products added to animal feed that provide medicines to livestock; and

•animal health diagnostics: portable blood and urine analysis systems and point-of-care diagnostic products, including instruments and reagents, rapid immunoassay tests, reference laboratory kits and blood glucose monitors.

Our remaining revenue is derived from other non-pharmaceutical product categories, such as nutritionals and agribusiness, as well as products and services in smaller but fast growing areas, including biodevices, genetic tests and precision livestock farming.

Our livestock products primarily help prevent or treat diseases and conditions to enable the cost-effective production of safe, high-quality animal protein. Human population growth and increasing standards of living are important long-term growth drivers for our livestock products in three major ways. First, population growth and increasing standards of living drive increased demand for improved nutrition, particularly animal protein. Second, population growth leads to increased natural resource constraints driving a need for enhanced productivity. Finally, as standards of living improve, there is increased focus on food quality and safety.

Our companion animal products help extend and improve the quality of life for pets; increase convenience and compliance for pet owners; and help veterinarians improve the quality of their care and the efficiency of their businesses. Growth in the companion animal medicines, vaccines and diagnostics sector is driven by economic development, related increases in disposable income and increases in pet ownership and spending on pet care. Companion animals are also living longer, receiving increased medical treatment and benefiting from advances in animal health medicines and vaccines.

B. Revenue from Contracts with Customers

Contract liabilities reflected within Other current liabilities as of December 31, 2019 and December 31, 2018, and subsequently recognized as revenue during the first nine months of 2020 and 2019 were approximately $6 million and $8 million, respectively. Contract liabilities as of September 30, 2020 and December 31, 2019 were approximately $9 million and $11 million, respectively.

Estimated future revenue expected to be generated from long-term contracts with unsatisfied performance obligations as of September 30, 2020 is not material.

5. Acquisitions and Divestitures

A. Acquisitions

Other Acquisitions

In the third quarter of 2020, we completed the acquisitions of Fish Vet Group, a diagnostics company for aquaculture, and Virtual Recall, a veterinary engagement software company. In the second quarter of 2020, we completed the acquisition of Performance Livestock Analytics, a cloud-based technology company in the precision livestock business. We also entered into an option purchase agreement as part of a research and development arrangement with a Belgian company, a variable interest entity of which Zoetis is the primary beneficiary and now consolidating within our results. In the first quarter of 2020, we completed the acquisition of Ethos Diagnostic Science, a veterinary reference laboratory business with labs across the U.S. These transactions did not have a significant impact on our consolidated financial statements.

During 2019, we completed the acquisitions of Platinum Performance, a nutrition-focused animal health business for companion animals and Phoenix Lab and ZNLabs, both full service veterinary reference laboratory companies with networks of labs across the U.S. These transactions did not have a significant impact on our consolidated financial statements.

B. Divestitures

During the nine months ended September 30, 2020, we received cash proceeds of $20 million resulting from a payment received pursuant to an agreement related to the 2016 sale of certain U.S. manufacturing sites.

6. Restructuring Charges and Other Costs Associated with Acquisitions, Cost-Reduction and Productivity Initiatives

In connection with our cost-reduction/productivity initiatives, we typically incur costs and charges associated with site closings and other facility rationalization actions, workforce reductions and the expansion of shared services, including the development of global systems. In connection with our acquisition activity, we typically incur costs and charges associated with executing the transactions, integrating the acquired operations, which may include expenditures for consulting and the integration of systems and processes, product transfers and restructuring the consolidated company, which may include charges related to employees, assets and activities that will not continue in the consolidated company. All operating functions can be impacted by these actions, including sales and marketing, manufacturing and R&D, as well as functions such as information technology, shared services and corporate operations.

The components of costs incurred in connection with restructuring initiatives, acquisitions and cost-reduction/productivity initiatives are as follows:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,

8. Income Taxes

A. Taxes on Income

Our effective tax rate was 19.8% for the three months ended September 30, 2020, compared with 18.0% for the three months ended September 30, 2019. The higher effective tax rate for the three months ended September 30, 2020, was primarily attributable to:

•a $14 million net discrete tax benefit recorded in the three months ended September 30, 2019, due to a change in tax basis related to purchase accounting,

partially offset by:

•a $4 million and $1 million discrete tax benefit recorded in the three months ended September 30, 2020 and 2019, respectively, related to the excess tax benefits for share-based payments.

Our effective tax rate was 18.9% for the nine months ended September 30, 2020, compared with 18.2% for the nine months ended September 30, 2019. The higher effective tax rate for the nine months ended September 30, 2020, was primarily attributable to:

•changes in the jurisdictional mix of earnings, which includes the impact of the location of earnings from operations and repatriation costs. The jurisdictional mix of earnings can vary as a result of repatriation decisions, operating fluctuations in the normal course of business and the impact of non-deductible items;

•a $19 million net discrete tax benefit recorded in the nine months ended September 30, 2019, primarily related to the effective settlement of certain issues with non-U.S. tax authorities and a prior period tax adjustment; and

•a $14 million net discrete deferred tax benefit recorded in the nine months ended September 30, 2019, due to a change in tax basis related to purchase accounting,

partially offset by:

•a $29 million and $17 million discrete tax benefit recorded in the nine months ended September 30, 2020 and 2019, respectively, related to the excess tax benefits for share-based payments;

•a $7 million discrete tax benefit recorded in the nine months ended September 30, 2020 related to a remeasurement of deferred taxes resulting from the integration of acquired businesses; and

•a $4 million and $3 million discrete tax benefit recorded in the nine months ended September 30, 2020 and 2019, respectively, related to a remeasurement of deferred taxes as a result of a change in non-U.S. statutory tax rates.

B. Deferred Taxes

As of September 30, 2020, the total net deferred income tax liability of $313 million is included in Noncurrent deferred tax assets ($97 million) and Noncurrent deferred tax liabilities ($410 million).

As of December 31, 2019, the total net deferred income tax liability of $346 million is included in Noncurrent deferred tax assets ($88 million) and Noncurrent deferred tax liabilities ($434 million).

C. Tax Contingencies

As of September 30, 2020, the net tax liabilities associated with uncertain tax positions of $192 million (exclusive of interest and penalties related to uncertain tax positions of $14 million) are included in Noncurrent deferred tax assets and Other noncurrent assets ($2 million) and Other taxes payable ($190 million).

12 |

As of December 31, 2019, the net tax liabilities associated with uncertain tax positions of $182 million (exclusive of interest and penalties related to uncertain tax positions of $12 million) are included in Noncurrent deferred tax assets and Other noncurrent assets ($2 million) and Other taxes payable ($180 million).

Our tax liabilities for uncertain tax positions relate primarily to issues common among multinational corporations. Any settlements or statute of limitations expirations could result in a significant decrease in our uncertain tax positions. Substantially all of these unrecognized tax benefits, if recognized, would impact our effective income tax rate. We do not expect that within the next twelve months any of our uncertain tax positions could significantly decrease as a result of settlements with taxing authorities or the expiration of the statutes of limitations. Our assessments are based on estimates and assumptions that have been deemed reasonable by management, but our estimates of uncertain tax positions and potential tax benefits may not be representative of actual outcomes, and any variation from such estimates could materially affect our financial statements in the period of settlement or when the statutes of limitations expire, as we treat these events as discrete items in the period of resolution. Finalizing audits with the relevant taxing authorities can include formal administrative and legal proceedings, and, as a result, it is difficult to estimate the timing and range of possible changes related to our uncertain tax positions, and such changes could be significant.

9. Financial Instruments

A. Debt

Credit Facilities

In December 2016, we entered into an amended and restated revolving credit agreement with a syndicate of banks providing for a multi-year $1.0 billion senior unsecured revolving credit facility (the credit facility). In December 2018, the maturity for the amended and restated revolving credit agreement was extended through December 2023. Subject to certain conditions, we have the right to increase the credit facility to up to $1.5 billion. The credit facility contains a financial covenant requiring us to not exceed a maximum total leverage ratio (the ratio of consolidated net debt as of the end of the period to consolidated Earnings Before Interest, Income Taxes, Depreciation and Amortization (EBITDA) for such period) of 3.50:1. Upon entering into a material acquisition, the maximum total leverage ratio increases to 4.00:1, and extends until the fourth full consecutive fiscal quarter ended immediately following the consummation of a material acquisition.

The credit facility also contains a financial covenant requiring that we maintain a minimum interest coverage ratio (the ratio of EBITDA at the end of the period to interest expense for such period) of 3.50:1. In addition, the credit facility contains other customary covenants.

We were in compliance with all financial covenants as of September 30, 2020, and December 31, 2019. There were no amounts drawn under the credit facility as of September 30, 2020 or December 31, 2019.

We have additional lines of credit and other credit arrangements with a group of banks and other financial intermediaries for general corporate purposes. We maintain cash and cash equivalent balances in excess of our outstanding short-term borrowings. As of September 30, 2020, we had access to $77 million of lines of credit which expire at various times through 2020 and are generally renewed annually. There were $1.4 million of borrowings outstanding related to these facilities as of September 30, 2020 and no borrowings outstanding as of December 31, 2019.

Commercial Paper Program

In February 2013, we entered into a commercial paper program with a capacity of up to $1.0 billion. As of September 30, 2020 and December 31, 2019, there was no commercial paper outstanding under this program.

Senior Notes and Other Long-Term Debt

On May 12, 2020, we issued $1.25 billion aggregate principal amount of our senior notes (2020 senior notes), with an original issue discount of $10 million. These notes are comprised of $750 million aggregate principal amount of 2.000% senior notes due 2030 and $500 million aggregate principal amount of 3.000% senior notes due 2050. The net proceeds were to be used to repay the principal of our 3.450% senior notes due 2020 in the aggregate principal amount of $500 million and the remainder will be used for general corporate purposes. On October 13, 2020, we redeemed in full the $500 million aggregate principal amount of our 3.450% 2015 senior notes due 2020. For additional information, see Note 17 - Subsequent Events.

On August 20, 2018, we issued $1.5 billion aggregate principal amount of our senior notes (2018 senior notes), with an original issue discount of $4 million. On September 12, 2017, we issued $1.25 billion aggregate principal amount of our senior notes (2017 senior notes), with an original issue discount of $7 million. On November 13, 2015, we issued $1.25 billion aggregate principal amount of our senior notes (2015 senior notes), with an original issue discount of $2 million. On January 28, 2013, we issued $3.65 billion aggregate principal amount of our senior notes (2013 senior notes) in a private placement, with an original issue discount of $10 million.

The 2013, 2015, 2017, 2018 and 2020 senior notes are governed by an indenture and supplemental indenture (collectively, the indenture) between us and Deutsche Bank Trust Company Americas, as trustee. The indenture contains certain covenants, including limitations on our and certain of our subsidiaries' ability to incur liens or engage in sale-leaseback transactions. The indenture also contains restrictions on our ability to consolidate, merge or sell substantially all of our assets. In addition, the indenture contains other customary terms, including certain events of default, upon the occurrence of which the 2013, 2015, 2017, 2018 and 2020 senior notes may be declared immediately due and payable.

Pursuant to the indenture, we are able to redeem the 2013, 2015, 2017 and 2020 senior notes and the 2018 fixed rate senior notes or any series, in whole or in part, at any time by paying a “make whole” premium, plus accrued and unpaid interest to, but excluding, the date of redemption. The 2018 floating rate senior notes are not redeemable at our option prior to their maturity date. Pursuant to our tax matters agreement with Pfizer, we will not be permitted to redeem the 2013 senior notes due 2023 pursuant to this optional redemption provision, except under limited circumstances. Upon the occurrence of a change of control of us and a downgrade of the 2013, 2015, 2017, 2018 and 2020 senior notes below an investment grade rating by each of Moody's Investors Service, Inc. and Standard & Poor's Ratings Services, we are, in certain circumstances,

13 |

required to make an offer to repurchase all of the outstanding 2013, 2015, 2017, 2018 and 2020 senior notes at a price equal to 101% of the aggregate principal amount of the 2013, 2015, 2017, 2018 and 2020 senior notes together with accrued and unpaid interest to, but excluding, the date of repurchase.

The components of our long-term debt are as follows:

The fair value of our long-term debt was $7,711 million and $6,587 million as of September 30, 2020, and December 31, 2019, respectively, and has been determined using a third-party matrix-pricing model that uses significant inputs derived from, or corroborated by, observable market data and Zoetis’ credit rating (Level 2 inputs).

The principal amount of long-term debt outstanding, as of September 30, 2020, matures in the following years:

Interest Expense

Interest expense, net of capitalized interest, was $62 million and $173 million for the three and nine months ended September 30, 2020, respectively, and $56 million and $167 million for the three and nine months ended September 30, 2019, respectively. Capitalized interest expense was $4 million and $12 million for the three and nine months ended September 30, 2020, respectively, and $3 million and $9 million for the three and nine months ended September 30, 2019, respectively.

B. Derivative Financial Instruments

Foreign Exchange Risk

A significant portion of our revenue, earnings and net investment in foreign affiliates is exposed to changes in foreign exchange rates. We seek to manage our foreign exchange risk, in part, through operational means, including managing same-currency revenue in relation to same-currency costs and same-currency assets in relation to same-currency liabilities. Depending on market conditions, foreign exchange risk is also managed through the use of various derivative financial instruments. These derivative financial instruments serve to manage the exposure of our net investment in certain foreign operations to changes in foreign exchange rates and protect net income against the impact of translation into U.S. dollars of certain foreign exchange-denominated transactions.

All derivative financial instruments used to manage foreign currency risk are measured at fair value and are reported as assets or liabilities on the condensed consolidated balance sheet. The derivative financial instruments primarily offset exposures in the Australian dollar, British pound, Canadian dollar, Chinese yuan, euro, and Japanese yen. Changes in fair value are reported in earnings or in Accumulated other comprehensive income/(loss), depending on the nature and purpose of the financial instrument, as follows:

•For foreign exchange contracts not designated as hedging instruments, we recognize the gains and losses on forward-exchange contracts that are used to offset the same foreign currency assets or liabilities immediately into earnings along with the earnings impact of the items they generally offset. These contracts essentially take the opposite currency position of that reflected in the month-end balance sheet to counterbalance the effect of any currency movement. The vast majority of the foreign exchange derivative financial instruments mature within 60 days and all mature within three years.

•For cross-currency interest rate swaps, which are designated as a hedge against our net investment in foreign operations, changes in the fair value are recorded as a component of cumulative translation adjustment within Accumulated other comprehensive income/

14 |

(loss) and reclassified into earnings when the foreign investment is sold or substantially liquidated. Gains and losses excluded from the assessment of hedge effectiveness are recognized in earnings (Interest expense—net of capitalized interest). The cash flows from these contracts are reflected within the investing section of our Condensed Consolidated Statement of Cash Flows. The cross-currency interest rate swap contracts have varying maturities of up to five years.

Interest Rate Risk

The company may use interest rate swap contracts on certain investing and borrowing transactions to manage its net exposure to interest rates and to reduce its overall cost of borrowing.

•During the second quarter of 2020, we entered into treasury lock trades with an aggregate notional value of $600 million. We designated these treasury locks as cash flow hedges against interest rate exposure related to the issuance of fixed-rate debt in the second quarter of 2020. Of the aggregate notional value of $600 million, four treasury locks with a total notional amount of $425 million were designated as hedges against the ten-year fixed rate debt maturing in 2030, and two treasury locks with a total notional amount of $175 million were designated as hedges against the thirty-year note maturing in 2050. Upon issuance of our 2020 senior notes, we terminated the treasury locks and paid $6 million in cash to the counterparties for settlement. The settlement amount, which represents the fair value of the contracts at the time of termination, was recorded in Accumulated other comprehensive loss, and will be amortized into income over the life of the 2020 senior notes.

•In anticipation of issuing fixed-rate debt, we may use forward-starting interest rate swaps that are designated as cash flow hedges to hedge against changes in interest rates that could impact expected future issuances of debt. Unrealized gains or losses on the forward-starting interest rate swaps are reported in Accumulated other comprehensive loss and are recognized in earnings over the life of the future fixed-rate notes. When the company discontinues hedge accounting because it is no longer probable that an anticipated transaction will occur within the originally expected period of execution, or within an additional two-month period thereafter, changes to fair value accumulated in other comprehensive income are recognized immediately in earnings. For the nine months ended September 30, 2020, we entered into forward-starting interest rate swaps, having an effective date and mandatory termination date in March 2023, to hedge against interest rate exposure related principally to the anticipated future issuance of fixed-rate debt to be used primarily to refinance our 3.250% 2013 senior notes due 2023, and a forward-starting interest rate swap, having an effective date and mandatory termination date in March 2026, to hedge against interest rate exposure related principally to the anticipated future issuance of fixed-rate debt to be used primarily to refinance our 4.500% senior notes due 2025.

•We may use fixed-to-floating interest rate swaps that are designated as fair value hedges to hedge against changes in the fair value of certain fixed-rate debt attributable to changes in the benchmark LIBOR rate. These derivative instruments effectively convert a portion of the company’s long-term debt from fixed rate to floating rate debt based on three-month LIBOR plus a spread. Gains or losses on the fixed-to-floating interest rate swaps due to changes in LIBOR are recorded in Interest expense, net of capitalized interest. Changes in the fair value of the fixed-to-floating interest rate swaps are offset by changes in the fair value of the underlying fixed rate debt. As of September 30, 2020, we had an outstanding fixed-to-floating interest rate swap that corresponds to a portion of the 3.900% 2018 senior notes due 2028. The amounts recorded during the three and nine months ended September 30, 2020 for changes in the fair value of this hedge are not material to our consolidated financial statements.

The company’s cross-currency interest rate swaps are subject to master netting arrangements to mitigate credit risk by permitting net settlement of transactions with the same counterparty. We may also enter into collateral security arrangements with certain of our counterparties to exchange cash collateral when the net fair value of certain derivative instruments fluctuates from contractually established thresholds. At September 30, 2020, there was $16 million of collateral received related to the long-term cross-currency interest rate swaps recorded in Other noncurrent assets.

We use a market approach in valuing financial instruments on a recurring basis. Our derivative financial instruments are measured at fair value on a recurring basis using Level 2 inputs in the calculation of fair value.

The amounts of net gains on derivative instruments not designated as hedging instruments, recorded in Other (income)/deductions—net, are as follows:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,
(MILLIONS OF DOLLARS)	2020		2019		2020		2019
Foreign currency forward-exchange contracts	$	—	$	1	$	10	$	5

These amounts were substantially offset in Other (income)/deductions—net by the effect of changing exchange rates on the underlying foreign currency exposures.

The amounts of unrecognized net gains/(losses) on interest rate swap contracts, recorded, net of tax, in Accumulated other comprehensive income/(loss), are as follows:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,
(MILLIONS OF DOLLARS)	2020		2019		2020		2019
Forward-starting interest rate swap contracts	$	5	$	(4)	$	(22)	$	(4)

12. Share-based Payments

The Zoetis 2013 Equity and Incentive Plan (the Equity Plan) provides long-term incentives to our employees and non-employee directors. The principal types of share-based awards available under the Equity Plan may include, but are not limited to, stock options, restricted stock and restricted stock units (RSUs), deferred stock units (DSUs), performance-vesting restricted stock units (PSUs) and other equity-based or cash-based awards.

The components of share-based compensation expense are as follows:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,
(MILLIONS OF DOLLARS)	2020		2019		2020		2019
Stock options / stock appreciation rights	$	2	$	3	$	7	$	8
RSUs / DSUs(a)(b)	7		10		24		34
PSUs	5		3		15		9
Share-based compensation expense—total(c)	$	14	$	16	$	46	$	51

(a) For the three and nine months ended September 30, 2019, includes share-based compensation expense of $4 million and $13 million, respectively related to the acquisition of Abaxis, for the post-merger service period.

(b)     Includes additional share-based compensation expense as a result of accelerated vesting of outstanding RSUs of terminated employees in connection with the acquisition of Abaxis, for the three and nine months ended September 30, 2019 of approximately $1 million and $5 million, respectively, which is included in Restructuring charges and certain acquisition-related costs.

(c)     Amounts capitalized to inventory were insignificant for the three and nine months ended September 30, 2020 and three months ended September 30, 2019 and $1 million for the nine months ended September 30, 2019.

During the nine months ended September 30, 2020, the company granted 292,727 stock options with a weighted-average exercise price of $143.23 per stock option and a weighted-average fair value of $33.83 per stock option. The fair-value based method for valuing each Zoetis stock option grant on the grant date uses the Black-Scholes-Merton option-pricing model, which incorporates a number of valuation assumptions. The weighted-average fair value was estimated based on the following assumptions: risk-free interest rate of 1.46%; expected dividend yield of 0.55%; expected stock price volatility of 24.22%; and expected term of 5.5 years. In general, stock options vest after three years of continuous service and the values determined through this fair-value based method generally are amortized on a straight-line basis over the vesting term into Cost of sales, Selling, general and administrative expenses, or Research and development expenses, as appropriate.

During the nine months ended September 30, 2020, the company granted 234,064 RSUs, with a weighted-average grant date fair value of $143.68 per RSU. RSUs are accounted for using a fair-value-based method that utilizes the closing price of Zoetis common stock on the date of grant. In general, RSUs vest after three years of continuous service from the grant date and the values generally are amortized on a straight-line basis over the vesting term into Cost of sales, Selling, general and administrative expenses, or Research and development expenses, as appropriate.

During the nine months ended September 30, 2020, the company granted 85,279 PSUs with a weighted-average grant date fair value of $217.49 per PSU. PSUs are accounted for using a Monte Carlo simulation model. The units underlying the PSUs will be earned and vested over a three-year performance period, based upon the total shareholder return of the company in comparison to the total shareholder return of the companies comprising the S&P 500 stock market index at the start of the performance period, excluding companies that during the performance period are acquired or no longer publicly traded (Relative TSR). The weighted-average fair value was estimated based on volatility assumptions of Zoetis common stock and an average of the S&P 500 companies, which were 20.2% and 24.8%, respectively. Depending on the company’s Relative TSR performance at the end of the performance period, the recipient may earn from 0% to 200% of the target number of units. Vested units are settled in shares of the company’s common stock. PSU values are amortized on a straight-line basis over the vesting term into Cost of sales, Selling, general and administrative expenses, or Research and development expenses, as appropriate.

13. Stockholders' Equity

Zoetis is authorized to issue 6 billion shares of common stock and 1 billion shares of preferred stock.

In December 2018, the company's Board of Directors authorized a $2.0 billion share repurchase program. As of September 30, 2020, there was approximately $1.4 billion remaining under this authorization. Purchases of Zoetis shares may be made at the discretion of management, depending on market conditions and business needs. The company temporarily suspended share repurchases beginning in the second quarter of 2020.

Weighted-average common and potential dilutive shares outstanding	478.5		481.5		478.5		482.3
Earnings per share attributable to Zoetis Inc. stockholders—basic	$	1.01	$	0.91	$	2.69	$	2.33
Earnings per share attributable to Zoetis Inc. stockholders—diluted	$	1.00	$	0.90	$	2.67	$	2.31

The number of stock options outstanding under the company's Equity Plan that were excluded from the computation of diluted earnings per share, as the effect would have been antidilutive, were de minimis for the three and nine months ended September 30, 2020 and September 30, 2019.

15. Commitments and Contingencies

We and certain of our subsidiaries are subject to numerous contingencies arising in the ordinary course of business. For a discussion of our tax contingencies, see Note 8. Income Taxes.

A. Legal Proceedings

Our non-tax contingencies include, among others, the following:

•    Product liability and other product-related litigation, which can include injury, consumer, off-label promotion, antitrust and breach of contract claims.

•    Commercial and other matters, which can include product-pricing claims and environmental claims and proceedings.

•    Patent litigation, which typically involves challenges to the coverage and/or validity of our patents or those of third parties on various products or processes.

•    Government investigations, which can involve regulation by national, state and local government agencies in the U.S. and in other countries.

Certain of these contingencies could result in losses, including damages, fines and/or civil penalties, and/or criminal charges, which could be substantial.

We believe that we have strong defenses in these types of matters, but litigation is inherently unpredictable and excessive verdicts do occur. We do not believe that any of these matters will have a material adverse effect on our financial position. However, we could incur judgments, enter

19 |

into settlements or revise our expectations regarding the outcome of certain matters, and such developments could have a material adverse effect on our results of operations or cash flows in the period in which the amounts are paid.

We have accrued for losses that are both probable and reasonably estimable. Substantially all of these contingencies are subject to significant uncertainties and, therefore, determining the likelihood of a loss and/or the measurement of any loss can be complex. Consequently, we are unable to estimate the range of reasonably possible loss in excess of amounts accrued. Our assessments are based on estimates and assumptions that have been deemed reasonable by management, but the assessment process relies on estimates and assumptions that may prove to be incomplete or inaccurate, and unanticipated events and circumstances may occur that might cause us to change those estimates and assumptions.

Amounts recorded for legal and environmental contingencies can result from a complex series of judgments about future events and uncertainties and can rely on estimates and assumptions.

The principal matters to which we are a party are discussed below. In determining whether a pending matter is significant for financial reporting and disclosure purposes, we consider both quantitative and qualitative factors in order to assess materiality, such as, among other things, the amount of damages and the nature of any other relief sought in the proceeding, if such damages and other relief are specified; our view of the merits of the claims and of the strength of our defenses; whether the action purports to be a class action and our view of the likelihood that a class will be certified by the court; the jurisdiction in which the proceeding is pending; any experience that we or, to our knowledge, other companies have had in similar proceedings; whether disclosure of the action would be important to a reader of our financial statements, including whether disclosure might change a reader’s judgment about our financial statements in light of all of the information about the company that is available to the reader; the potential impact of the proceeding on our reputation; and the extent of public interest in the matter. In addition, with respect to patent matters, we consider, among other things, the financial significance of the product protected by the patent.

Ulianopolis, Brazil

In February 2012, the Municipality of Ulianopolis (State of Para, Brazil) filed a complaint against Fort Dodge Saúde Animal Ltda. (FDSAL), a Zoetis entity, and five other large companies alleging that waste sent to a local waste incineration facility for destruction, but that was not ultimately destroyed as the facility lost its operating permit, caused environmental impacts requiring cleanup.

The Municipality is seeking recovery of cleanup costs purportedly related to FDSAL's share of all waste accumulated at the incineration facility awaiting destruction, and compensatory damages to be allocated among the six defendants. We believe we have strong arguments against the claim, including defense strategies against any claim of joint and several liability.

At the request of the Municipal prosecutor, in April 2012, the lawsuit was suspended for one year. Since that time, the prosecutor has initiated investigations into the Municipality's actions in the matter as well as the efforts undertaken by the six defendants to remove and dispose of their individual waste from the incineration facility. On October 3, 2014, the Municipal prosecutor announced that the investigation remained ongoing and outlined the terms of a proposed Term of Reference (a document that establishes the minimum elements to be addressed in the preparation of an Environmental Impact Assessment), under which the companies would be liable to withdraw the waste and remediate the area.

On March 5, 2015, we presented our response to the prosecutor’s proposed Term of Reference, arguing that the proposed terms were overly general in nature and expressing our interest in discussing alternatives to address the matter. The prosecutor agreed to consider our request to engage a technical consultant to conduct an environmental diagnostic of the contaminated area. On May 29, 2015, we, in conjunction with the other defendant companies, submitted a draft cooperation agreement to the prosecutor, which outlined the proposed terms and conditions for the engagement of a technical consultant to conduct the environmental diagnostic. On August 19, 2016, the parties and the prosecutor agreed to engage the services of a third-party consultant to conduct a limited environmental assessment of the site. The site assessment was conducted during June 2017, and a written report summarizing the results of the assessment was provided to the parties and the prosecutor in November 2017. The report noted that waste is still present on the site and that further (Phase II) environmental assessments are needed before a plan to manage that remaining waste can be prepared. On April 1, 2019, the defendants met with the Prosecutor to discuss the conclusions set forth in the written report. Following that discussion, on April 10, 2019, the Prosecutor issued a procedural order requesting that the defendants prepare and submit a technical proposal outlining the steps needed to conduct the additional Phase II environmental assessments. The defendants presented the technical proposal to the Prosecutor on October 21, 2019. On March 3, 2020, the Prosecutor notified the defendants that he submitted the proposal to the Ministry of the Environment for its review and consideration. On July 15, 2020, the Prosecutor recommended certain amendments to the proposal for the Phase II testing. On September 28, 2020, the parties and the Prosecutor agreed to the final terms and conditions concerning the cooperation agreement with respect to the Phase II testing. We anticipate that the Phase II testing shall begin shortly.

Lascadoil Contamination in Animal Feed

An investigation by the U.S. Food and Drug Administration (FDA) and the Michigan Department of Agriculture into the alleged contamination of the feed supply of certain turkey and hog feed mills in Michigan led to the recall of certain batches of soy oil (intended for use as an animal feed additive) that had originated with Shur-Green Farms LLC, a producer of soy oil, and that had been contaminated with lascadoil, an industrial by-product of certain Zoetis manufacturing processes. The contaminated feed is believed to have caused the deaths of approximately 50,000 turkeys and the contamination (but not death) of at least 20,000 hogs in August 2014. The investigation posited that Shur-Green inadvertently contaminated soy oil with lascadoil which it purchased from Zoetis for use as a bio-fuel ingredient, and then sold the contaminated soy oil to fat recycling vendors, who in turn unknowingly sold to feed mills for use in animal feed.

During the course of its investigation, the FDA identified the process used to manufacture Zoetis’ Avatec® (lasalocid sodium) and Bovatec® (lasalocid sodium) products as the possible source of the lascadoil, since lascadoil contains small amounts of lasalocid, the active ingredient found in both products. Zoetis sold the industrial lascadoil byproduct to Shur-Green, through its broker, Heritage Interactive Services, LLC. Under the terms of the sale agreement, the lascadoil could only be incinerated or resold for use in biofuel and the agreement expressly prohibited the reselling of lascadoil for use as a component in food. The FDA inspected the Zoetis site where Avatec and Bovatec are manufactured, and found no evidence that Zoetis was involved in the contamination of the animal feed.

20 |

On March 10, 2015, plaintiffs Restaurant Recycling, LLC (Restaurant Recycling) and Superior Feed Ingredients, LLC (Superior), both of whom are in the fat recycling business, filed a complaint in the Seventeenth Circuit Court for the State of Michigan against Shur-Green Farms alleging negligence and breach of warranty claims arising from their purchase of soy oil allegedly contaminated with lascadoil. Plaintiffs resold the allegedly contaminated soy oil to turkey feed mills for use in feed ingredient. Plaintiffs also named Zoetis as a defendant in the complaint alleging that Zoetis failed to properly manufacture its products and breached an implied warranty that the soy oil was fit for use at turkey and hog mills. Zoetis was served with the complaint on June 3, 2015, and we filed our answer, denying all allegations, on July 15, 2015. On August 10, 2015, several of the turkey feed mills filed a joint complaint against Restaurant Recycling, Superior, Shur-Green Farms and others, alleging claims for negligence, misrepresentation, and breach of warranty, arising out of their alleged purchase and use of the contaminated soy oil. The complaint raises only one count against Zoetis for negligence. We filed an answer to the complaint on November 2, 2015, denying the allegation. On May 16, 2016, two additional turkey producers filed a complaint in the Seventeenth Circuit Court for the State of Michigan against the company, Restaurant Recycling, Superior, Shur-Green Farms and others, alleging claims for negligence and breach of warranties. We filed an answer to the complaint on June 20, 2016, denying the allegations. The Court has consolidated all three cases in Michigan for purposes of discovery and disposition. On July 28, 2017, we filed a motion for summary disposition on the grounds that no genuine issues of material fact exist and that Zoetis is entitled to judgment as a matter of law. On October 19, 2017, the Court granted our motion and dismissed all claims against Zoetis. On October 31, 2017, the plaintiffs filed motions for reconsideration of the Court's decision granting summary disposition. The Court, denied all such motions on December 6, 2017, for the same reasons cited in the Court’s original decision. On December 27, 2017, the plaintiffs filed a request with the Michigan Court of Appeals seeking an interlocutory (or interim) appeal of the lower Court’s decision, which we opposed on January 17, 2018. On July 5, 2018, the Court of Appeals denied the plaintiffs’ request for an interlocutory appeal. The case was remanded back to the lower Court, where it was scheduled to proceed to trial by jury. We have been advised that the remaining parties have reached an agreement to settle the dispute, and on June 24, 2020, the remaining parties jointly stipulated to the dismissal of all remaining claims. On July 13, 2020, Plaintiffs filed a claim of appeal with Michigan State Circuit Court seeking reversal of the lower Court’s decision granting Zoetis’ motion for summary disposition. Plaintiffs’ filed their appeal brief on October 29, 2020, and our reply brief is due on December 3, 2020. We intend to fully defend the appeal.

Other Matters

On February 14, 2019, the General Court of the European Union (General Court) annulled the January 11, 2016 decision of the European Commission (EC) that selective tax advantages granted by Belgium under its "excess profit" tax scheme constitute illegal state aid. On May 8, 2019, the EC filed an appeal to the decision of the General Court. On September 16, 2019, the EC opened separate in-depth investigations to assess whether Belgium excess profit rulings granted to 39 multinational companies, including Zoetis, constituted state aid for those companies. Due to the uncertainty with respect to the outcome of the appeal to be filed by the EC, the company has not reflected any potential benefits associated with the decision of the General Court in its consolidated financial statements as of September 30, 2020. We will continue to monitor the developments of the appeal and its ultimate resolution.

The EC published a decision on alleged competition law infringements by several human health pharmaceutical companies on June 19, 2013. One of the involved legal entities is Alpharma LLC (previously having the name Zoetis Products LLC). Alpharma LLC's involvement is solely related to its human health activities prior to Pfizer's acquisition of King/Alpharma. Zoetis paid a fine in the amount of 11 million euros (approximately $14 million) and was reimbursed in full by Pfizer in accordance with the Global Separation Agreement between Pfizer and Zoetis, which provides that Pfizer is obligated to indemnify Zoetis for any liabilities arising out of claims not related to its animal health assets. We filed an appeal of the decision on September 6, 2013, to the General Court of the European Union. On September 8, 2016, the General Court upheld the decision of the European Commission. On November 25, 2016, we filed an appeal to the Court of Justice of the European Union. On January 24, 2019, the Court heard oral argument on the merits of the appeal. On June 4, 2020, the Advocate General issued his non-binding opinion, which largely confirmed the decision of the General Court. We now await the Court’s decision.

B. Guarantees and Indemnifications

In the ordinary course of business and in connection with the sale of assets and businesses, we indemnify our counterparties against certain liabilities that may arise in connection with the transaction or related to activities prior to the transaction. These indemnifications typically pertain to environmental, tax, employee and/or product-related matters and patent-infringement claims. If the indemnified party were to make a successful claim pursuant to the terms of the indemnification, we would be required to reimburse the loss. These indemnifications are generally subject to threshold amounts, specified claim periods and other restrictions and limitations. Historically, we have not paid significant amounts under these provisions and, as of September 30, 2020, recorded amounts for the estimated fair value of these indemnifications were not significant.

16. Segment Information

Operating Segments

We manage our operations through two geographic operating segments: the U.S. and International. Each operating segment has responsibility for its commercial activities. Within each of these operating segments, we offer a diversified product portfolio, including vaccines, anti-infectives, parasiticides, dermatology, medicated feed additives, animal health diagnostics and other pharmaceuticals, for both livestock and companion animal customers. Our chief operating decision maker uses the revenue and earnings of the two operating segments, among other factors, for performance evaluation and resource allocation.

In the first quarter of 2020, the company realigned certain management responsibilities. These changes did not impact the determination of our operating segments, however they resulted in the reallocation of certain costs between segments. These changes primarily include the following: (i) R&D costs related to our aquaculture business, which were previously reported in our international commercial segment, are now reported in Other business activities; (ii) certain other miscellaneous costs, which were previously reported in international commercial segment results, are now reported in Corporate; and (iii) certain diagnostic and other miscellaneous costs, which were previously reported in our U.S. results, are now reported in Corporate.

21 |

Other Costs and Business Activities

Certain costs are not allocated to our operating segment results, such as costs associated with the following:

•    Other business activities, includes our Client Supply Services (CSS) contract manufacturing results, our human health business, and expenses associated with our dedicated veterinary medicine research and development organization, research alliances, U.S. regulatory affairs and other operations focused on the development of our products. Other R&D-related costs associated with non-U.S. market and regulatory activities are generally included in the international commercial segment.

•    Corporate, includes platform functions such as information technology, facilities, legal, finance, human resources, business development, certain diagnostic costs and communications, among others. These costs also include compensation costs and other miscellaneous operating expenses not charged to our operating segments, as well as interest income and expense.

•Certain transactions and events such as (i) Purchase accounting adjustments, where we incur expenses associated with the amortization of fair value adjustments to inventory, intangible assets and property, plant and equipment; (ii) Acquisition-related activities, where we incur costs associated with acquiring and integrating newly acquired businesses, such as transaction costs and integration costs; and (iii) Certain significant items, which comprise substantive, unusual items that, either as a result of their nature or size, would not be expected to occur as part of our normal business on a regular basis, such as restructuring charges and implementation costs associated with our cost-reduction/productivity initiatives that are not associated with an acquisition, certain asset impairment charges, certain legal and commercial settlements and the impact of divestiture-related gains and losses.

•Other unallocated includes (i) certain overhead expenses associated with our global manufacturing operations not charged to our operating segments; (ii) certain costs associated with information technology and finance that specifically support our global manufacturing operations; (iii) certain supply chain and global logistics costs; and (iv) procurement costs.

Segment Assets

We manage our assets on a total company basis, not by operating segment. Therefore, our chief operating decision maker does not regularly review any asset information by operating segment and, accordingly, we do not report asset information by operating segment.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

Zoetis Inc.:

Results of Review of Interim Financial Information

We have reviewed the condensed consolidated balance sheet of Zoetis Inc. and subsidiaries (the Company) as of September 30, 2020, the related condensed consolidated statements of income, comprehensive income, and equity for the three-month and nine-month periods ended September 30, 2020 and 2019, the related condensed consolidated statements of cash flows for the nine-month periods ended September 30, 2020 and 2019, and the related notes (collectively, the consolidated interim financial information). Based on our reviews, we are not aware of any material modifications that should be made to the consolidated interim financial information for it to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2019, and the related consolidated statements of income, comprehensive income, equity, and cash flows for the year then ended (not presented herein); and in our report dated February 13, 2020, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2019, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Basis for Review Results

This consolidated interim financial information is the responsibility of the Company’s management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our reviews in accordance with the standards of the PCAOB. A review of consolidated interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

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

Overview of our business

We are a global leader in the discovery, development, manufacture and commercialization of animal health medicines, vaccines, and diagnostic products with a focus on both livestock and companion animals. For more than 65 years, we have been committed to enhancing the health of animals and bringing solutions to our customers who raise and care for them.

We manage our operations through two geographic operating segments: the United States (U.S.) and International. Within each of these operating segments, we offer a diversified product portfolio for both livestock and companion animal customers in order to capitalize on local and regional trends and customer needs. See Notes to Condensed Consolidated Financial Statements — Note 16. Segment Information.

We directly market our products to veterinarians and livestock producers located in approximately 45 countries across North America, Europe, Africa, Asia, Australia and South America, and are a market leader in nearly all of the major regions in which we operate. Through our efforts to establish an early and direct presence in many emerging markets, such as Brazil, China and Mexico, we believe we are one of the largest animal health medicines and vaccines business as measured by revenue across emerging markets as a whole. In markets where we do not have a direct commercial presence, we generally contract with distributors that provide logistics and sales and marketing support for our products.

We believe our investments in one of the industry’s largest sales organizations, including our extensive network of technical and veterinary operations specialists, our high-quality manufacturing and reliability of supply, and our long track record of developing products that meet customer needs, has led to enduring and valued relationships with our customers. Our research and development (R&D) efforts enable us to deliver innovative products to address unmet needs and evolve our product lines so they remain relevant for our customers.

Our products include over 300 products and product lines that we sell in over 100 countries for the prediction, prevention, detection and treatment of diseases and conditions that affect various livestock and companion animal species. The diversity of our product portfolio and our global operations provides stability to our overall business. For instance, in livestock, impacts on our revenue that may result from disease outbreaks or weather conditions in a particular market or region are often offset by increased sales in other regions from exports and species as consumers shift to other proteins.

In the first quarter of 2020, the company realigned certain management responsibilities. These changes did not impact the determination of our operating segments, however they resulted in the reallocation of certain costs between segments. These changes primarily include the following: (i) R&D costs related to our aquaculture business, which were previously reported in our international commercial segment, are now reported in Other business activities; (ii) certain other miscellaneous costs, which were previously reported in international commercial segment results, are now reported in Corporate; and (iii) certain diagnostics and other miscellaneous costs, which were previously reported in our U.S. results, are now reported in Corporate.

Certain reclassifications of prior year information have been made to conform to the current year's presentation.

A summary of our 2020 performance compared with the comparable 2019 period follows:

Our operating environment

For a description of our operating environment, including factors which could materially affect our business, financial condition, or future results, see "Our Operating Environment" in the MD&A of our 2019 Annual Report on Form 10-K. Set forth below are updates to certain of the factors disclosed in our 2019 Form 10-K.

Uncertainty Relating to COVID-19

We continue to closely monitor the impact of the coronavirus (COVID-19) pandemic and the resulting global recession on all aspects of our business across geographies, including how it has and may continue to impact our customers, workforce, suppliers and vendors. We are currently designated an essential business globally and have continued physical operations with respect to research and development, manufacturing and our supply chain. As the pandemic continues to progress, the severity of the impact across markets remains uncertain as the number of cases rises and falls in various jurisdictions leading to changes in the imposition of restrictive measures intended to contain the virus. The COVID-19 pandemic has had a significant impact on our results of operations during 2020 due to decreased demand attributable to the impact of COVID-19 on our customers and we anticipate that trend could continue for the remainder of 2020.

Due to numerous uncertainties regarding the continuing COVID-19 pandemic, we are unable to fully predict the impact that it will ultimately have on our future financial position and operating results. These uncertainties include the severity of the virus, the duration of the outbreak and number of recurrences, the effectiveness of measures to contain and treat the virus, governmental, business or other actions in response to the pandemic (which could include actions that result in limitations on, or disruptions to, our manufacturing, transportation and other operations, or mandates to provide products or services), impacts on our supply chain, the effect on customer demand, or changes to our operations. We cannot predict the impact that the COVID-19 pandemic will have on our customers, vendors and suppliers; however, any material effect on these parties could adversely impact us. In particular, our livestock customers have been, and may continue to be, negatively impacted by facility closures, reduced packing plant capacity, quarantines, travel bans and labor shortages, among other impacts. In addition, our companion animal customers have been, and may in the future be, negatively impacted by lack of demand for veterinary services in areas where lockdown and stay-at-home orders are in place. The impact of COVID-19 on our customers has reduced and could continue to reduce the demand for our products, which could continue to adversely impact our revenue. The health of our workforce, and our ability to meet staffing needs in our manufacturing operations and other critical functions also cannot be predicted and is vital to our operations. Further, the impacts of a prolonged global recession and the continued disruptions to, and volatility in, the credit and financial markets, as well as other unanticipated consequences, remain unknown. In addition, in order to preserve liquidity, we issued debt securities in May 2020 and we may in the future incur additional indebtedness, whether through the issuance of debt securities, drawdowns under our credit facility or otherwise. An increase in our outstanding indebtedness will result in additional interest expense.

The situation surrounding COVID-19 remains fluid, and we will continue to actively monitor the situation and may take actions that alter our business operations that we determine are in the best interests of our workforce, customers, vendors, suppliers, and other stakeholders, or as required by federal, state, or local authorities. It is not clear what the potential effects any such alterations or modifications may ultimately have on our business, including the effects on our customers, workforce, and prospects, or on our financial results for the remainder of fiscal 2020.

For further information regarding the impact of COVID-19 on the Company, please see Item 1A, Risk Factors in this report.

Quarterly Variability of Financial Results

Our quarterly financial results are subject to variability related to a number of factors including but not limited to: the impact of the COVID-19 pandemic discussed above, weather patterns, herd management decisions, economic conditions, regulatory actions, competitive dynamics, disease outbreaks, product and geographic mix, timing of price increases and timing of investment decisions.

Disease Outbreaks

Sales of our livestock products could be adversely affected by the outbreak of disease carried by animals. Outbreaks of disease may reduce regional or global sales of particular animal-derived food products or result in reduced exports of such products, either due to heightened export restrictions or import prohibitions, which may reduce demand for our products. Also, the outbreak of any highly contagious disease near our main production sites could require us to immediately halt production of our products at such sites or force us to incur substantial expenses in procuring raw materials or products elsewhere. Alternatively, sales of products that treat specific disease outbreaks may increase.

Foreign Exchange Rates

Significant portions of our revenue and costs are exposed to changes in foreign exchange rates. Our products are sold in more than 100 countries and, as a result, our revenue is influenced by changes in foreign exchange rates. For the nine months ended September 30, 2020, approximately 42% of our revenue was denominated in foreign currencies. We seek to manage our foreign exchange risk, in part, through operational means, including managing same-currency revenue in relation to same-currency costs and same-currency assets in relation to same-currency liabilities. As we operate in multiple foreign currencies, including the euro, Brazilian real, Chinese renminbi, Canadian dollar, Australian dollar, U.K. pound and other currencies, changes in those currencies relative to the U.S. dollar will impact our revenue, cost of goods and expenses, and consequently, net income. Exchange rate fluctuations may also have an impact beyond our reported financial results and directly impact operations. These fluctuations may affect the ability to buy and sell our goods and services between markets impacted by significant exchange rate variances. For the nine months ended September 30, 2020, approximately 58% of our total revenue was in U.S. dollars. Our year-over-year total revenue growth was unfavorably impacted by approximately 3% from changes in foreign currency values relative to the U.S. dollar.

Non-GAAP financial measures

We report information in accordance with U.S. generally accepted accounting principles (GAAP). Management also measures performance using non-GAAP financial measures that may exclude certain amounts from the most directly comparable GAAP measure. Despite the

26 |

importance of these measures to management in goal setting and performance measurement, non-GAAP financial measures have no standardized meaning prescribed by U.S. GAAP and, therefore, have limits in their usefulness to investors and may not be comparable to the calculation of similar measures of other companies. We present certain identified non-GAAP measures solely to provide investors with useful information to more fully understand how management assesses performance.

Operational Growth

We believe that it is important to not only understand overall revenue and earnings growth, but also “operational growth.” Operational growth is a non-GAAP financial measure defined as revenue or earnings growth excluding the impact of foreign exchange. This measure provides information on the change in revenue and earnings as if foreign currency exchange rates had not changed between the current and prior periods to facilitate a period-to-period comparison. We believe this non-GAAP measure provides a useful comparison to previous periods for the company and investors, but should not be viewed as a substitute for U.S. GAAP reported growth.

Adjusted Net Income and Adjusted Earnings Per Share

Adjusted net income and the corresponding adjusted earnings per share (EPS) are non-GAAP financial measures of performance used by management. We believe these financial measures are useful supplemental information to investors when considered together with our U.S. GAAP financial measures. We report adjusted net income to portray the results of our major operations, and the discovery, development, manufacture and commercialization of our products, prior to considering certain income statement elements. We define adjusted net income and adjusted EPS as net income attributable to Zoetis and EPS before the impact of purchase accounting adjustments, acquisition-related costs and certain significant items.

We recognize that, as an internal measure of performance, the adjusted net income and adjusted EPS measures have limitations, and we do not restrict our performance management process solely to these metrics. A limitation of the adjusted net income and adjusted EPS measures is that they provide a view of our operations without including all events during a period, such as the effects of an acquisition or amortization of purchased intangibles, and do not provide a comparable view of our performance to other companies. The adjusted net income and adjusted EPS measures are not, and should not be viewed as, a substitute for U.S. GAAP reported net income and reported EPS. See the Adjusted Net Income section below for more information.

Our effective tax rate was 19.8% for the three months ended September 30, 2020, compared with 18.0% for the three months ended September 30, 2019. The higher effective tax rate for the three months ended September 30, 2020, was primarily attributable to:

•a $14 million net discrete tax benefit recorded in the three months ended September 30, 2019, due to a change in tax basis related to purchase accounting,

partially offset by:

•a $4 million and $1 million discrete tax benefit recorded in the three months ended September 30, 2020 and 2019, respectively, related to the excess tax benefits for share-based payments.

Nine months ended September 30, 2020 vs. nine months ended September 30, 2019

Our effective tax rate was 18.9% for the nine months ended September 30, 2020, compared with 18.2% for the nine months ended September 30, 2019. The higher effective tax rate for the nine months ended September 30, 2020, was primarily attributable to:

•changes in the jurisdictional mix of earnings, which includes the impact of the location of earnings from operations and repatriation costs. The jurisdictional mix of earnings can vary as a result of repatriation decisions, operating fluctuations in the normal course of business and the impact of non-deductible items;

•a $19 million net discrete tax benefit recorded in the nine months ended September 30, 2019, primarily related to the effective settlement of certain issues with non-U.S. tax authorities and a prior period tax adjustment; and

•a $14 million net discrete deferred tax benefit recorded in the nine months ended September 30, 2019, due to a change in tax basis related to purchase accounting,

partially offset by:

•a $29 million and $17 million discrete tax benefit recorded in the nine months ended September 30, 2020 and 2019, respectively, related to the excess tax benefits for share-based payments;

•a $7 million discrete tax benefit recorded in the nine months ended September 30, 2020 related to a remeasurement of deferred taxes resulting from the integration of acquired businesses; and

•a $4 million and $3 million discrete tax benefit recorded in the nine months ended September 30, 2020 and 2019, respectively, related to a remeasurement of deferred taxes as a result of a change in non-U.S. statutory tax rates.

Three months ended September 30, 2020 vs. three months ended September 30, 2019

U.S. operating segment

U.S. segment revenue increased by $152 million, or 18%, in the three months ended September 30, 2020, compared with the three months ended September 30, 2019, reflecting increases of approximately $114 million in companion animal products and increases of approximately $38 million in livestock products.

•Companion animal revenue growth was driven primarily by increased sales in the Simparica® franchise, including revenues from Simparica Trio®, our new triple combination parasiticide for dogs, our key dermatology portfolio, sales of small animal vaccines and diagnostics, including the recent acquisition of a number of regional diagnostic reference labs.

•Livestock revenue increased mainly due to cattle products returning to historical buying patterns in response to improving market conditions following the impact of COVID-19 in the second quarter of this year, as well as an earlier fall cattle run compared to last year. Poultry products declined due to customer rotations reducing sales for our medicated feed additive products. Swine products declined due to disruptions in the food supply chain including reduced producer processing capacity that impacted producer profitability.

U.S. segment earnings increased by $94 million, or 17%, in the three months ended September 30, 2020, compared with the three months ended September 30, 2019, primarily due to revenue growth partially offset by higher operating expenses for investments to support revenue growth.

International operating segment

International segment revenue increased by $46 million, or 6%, in the three months ended September 30, 2020, compared with the three months ended September 30, 2019. Operational revenue increased by $81 million, or 11%, driven by growth of approximately $56 million in companion animal products and growth of approximately $25 million in livestock products.

•Companion animal operational revenue growth resulted primarily from increased sales in China as a result of favorable market conditions and additional promotional and educational efforts. Also contributing to growth in the quarter was our parasiticide products

34 |

including the Simparica franchise with the recent launch of Simparica Trio in the EU, Canada and Australia, as well as the Revolution®/Stronghold® franchise. Key dermatology products contributed to growth with increased sales of Apoquel® and Cytopoint®. Sales of companion animal products, including vaccines, also benefited as clinics expanded their operations following less COVID-19 related restrictions.

•Livestock operational revenue growth was driven by increased sales in swine, fish and cattle while poultry was flat in the quarter. Sales of swine products grew as a result of expanding herd production in key accounts and increased biosecurity measures in the wake of African Swine Fever in China. In other key global swine markets, vaccine sales increased as a result of favorable market conditions including increased production and export opportunities. Growth in the fish portfolio was driven primarily by increased market share for salmon vaccines and the acquisition of Fish Vet Group. Cattle products grew modestly based on a strong performance in Brazil.

•Additionally, International segment revenue was unfavorably impacted by foreign exchange, which decreased revenue by approximately $35 million, or 5%, primarily driven by the depreciation of the Brazilian real, Argentinian peso, and Mexican peso, partially offset by the euro.

International segment earnings increased by $47 million, or 13%, in the three months ended September 30, 2020, compared with the three months ended September 30, 2019. Operational earnings growth was $71 million, or 20%, primarily due to higher revenue and lower operating expenses, partially offset by higher cost of sales.

Nine months ended September 30, 2020 vs. nine months ended September 30, 2019

U.S. operating segment

U.S. segment revenue increased by $263 million, or 11%, in the nine months ended September 30, 2020, compared with the nine months ended September 30, 2019, reflecting increases of approximately $262 million in companion animal products and increases of approximately $1 million in livestock products.

•Companion animal revenue growth was driven primarily by increased sales of parasiticides including Simparica Trio our new triple combination parasiticide, the key dermatology portfolio and recent acquisitions of Platinum Performance, as well as a number of regional diagnostic reference labs.

•Livestock revenue was essentially flat due to limited growth in cattle offset by declines in swine. The increase in cattle was primarily due to an earlier fall cattle run in the third quarter this year compared to last year. Swine growth in the first quarter of 2020 was offset by decreased demand attributable to the negative impacts of COVID-19 in the second and third quarters of 2020.

U.S. segment earnings increased by $161 million, or 11%, in the nine months ended September 30, 2020, compared with the nine months ended September 30, 2019, primarily due to revenue and gross margin growth, partially offset by higher operating expenses for investments to support revenue growth.

International operating segment

International segment revenue increased by $22 million, or 1%, in the nine months ended September 30, 2020, compared with the nine months ended September 30, 2019. Operational revenue increased by $136 million, or 6%, driven by growth of approximately $86 million in companion animal products and growth of approximately $50 million in livestock products.

•Companion animal operational revenue growth resulted primarily from increased sales of our parasiticide products including the Simparica franchise with the launch of Simparica Trio in the EU, Canada and Australia, as well as the Revolution/Stronghold franchise. Key dermatology products also contributed to growth with increased sales of Apoquel and Cytopoint.

•Livestock operational revenue growth was driven by increased sales in swine, fish and poultry while cattle declined. Sales of swine products grew as a result of expanding herd production and increased biosecurity measures in the wake of African Swine Fever in China. Alpha Flux, a recently launched parasiticide that controls sea lice in salmon, increased market share and the recent acquisition of Fish Vet Group were the primary drivers of growth in fish. Growth in our poultry portfolio was due mainly to medicated feed additives. Sales of cattle products declined due to decreased demand attributable to the impact of COVID-19 in certain markets as well as the discontinuation of non-core products in Brazil.

•Additionally, International segment revenue was unfavorably impacted by foreign exchange which decreased revenue by approximately $114 million, or 5%, primarily driven by the depreciation of the Brazilian real, Argentine peso, Mexican peso and Australian dollar.

International segment earnings increased by $34 million, or 3%, in the nine months ended September 30, 2020, compared with the nine months ended September 30, 2019. Operational earnings growth was $110 million, or 10%, primarily due to higher revenue and lower operating expenses, partially offset by higher cost of sales.

Other business activities

Other business activities includes our Client Supply Services (CSS) contract manufacturing results, our human health business and expenses associated with our dedicated veterinary medicine research and development organization, research alliances, U.S. regulatory affairs and other operations focused on the development of our products. Other R&D-related costs associated with non-U.S. market and regulatory activities are generally included in the International segment.

35 |

Three months ended September 30, 2020 vs. three months ended September 30, 2019

Other business activities net loss was flat in the three months ended September 30, 2020, compared with the three months ended September 30, 2019, reflecting an increase in certain compensation-related expenses, offset by lower spending in project investments related to the COVID-19 pandemic, lower travel and entertainment expenses as a result of decreases in travel and events related to the COVID-19 pandemic and favorable foreign exchange.

Nine months ended September 30, 2020 vs. nine months ended September 30, 2019

Other business activities net loss increased by $18 million, in the nine months ended September 30, 2020, compared with the nine months ended September 30, 2019, reflecting an increase in R&D costs due to an increase in compensation-related costs and in project investments, partially offset by lower travel and entertainment expenses as a result of decreases in travel and events related to the COVID-19 pandemic and favorable foreign exchange.

Reconciling items

Reconciling items include certain costs that are not allocated to our operating segments results, such as costs associated with the following:

•Corporate, which includes certain costs associated with information technology, facilities, legal, finance, human resources, business development and communications, among others. These costs also include certain compensation costs, certain procurement costs, and other miscellaneous operating expenses that are not charged to our operating segments, as well as interest income and expense;

•Certain transactions and events such as (i) Purchase accounting adjustments, which includes expenses associated with the amortization of fair value adjustments to inventory, intangible assets, and property, plant and equipment; (ii) Acquisition-related activities, which includes costs for acquisition and integration; and (iii) Certain significant items, which includes non-acquisition-related restructuring charges, certain asset impairment charges, certain legal and commercial settlements, and costs associated with cost reduction/productivity initiatives; and

•Other unallocated, which includes (i) certain overhead expenses associated with our global manufacturing operations not charged to our operating segments; (ii) certain costs associated with information technology and finance that specifically support our global manufacturing operations; (iii) certain supply chain and global logistics costs; and (iv) certain procurement costs.

Three months ended September 30, 2020 vs. three months ended September 30, 2019

Corporate expenses increased by $35 million, or 20%, in the three months ended September 30, 2020, compared with the three months ended September 30, 2020, primarily due to an increase in expenses related to certain performance-related compensation costs, depreciation and recent acquisitions, partially offset by favorable foreign exchange.

Other unallocated expenses increased by $23 million, or 32%, in the three months ended September 30, 2020, compared with the three months ended September 30, 2020, primarily due to higher inventory obsolescence and other charges and unfavorable foreign exchange, partially offset by continued cost improvements and efficiencies in our manufacturing network.

Nine months ended September 30, 2020 vs. nine months ended September 30, 2019

Corporate expenses increased by $47 million, or 9%, in the nine months ended September 30, 2020, compared with the nine months ended September 30, 2019, primarily due to an increase in expenses related to depreciation and recent acquisitions, partially offset by a decrease in certain compensation-related costs and favorable foreign exchange.

Other unallocated expenses increased by $12 million, or 5%, in the nine months ended September 30, 2020, compared with the nine months ended September 30, 2019, primarily due to higher inventory obsolescence and other charges and unfavorable foreign exchange, partially offset by continued cost improvements and efficiencies in our manufacturing network.

Adjusted net income

General description of adjusted net income (a non-GAAP financial measure)

Adjusted net income is an alternative view of performance used by management, and we believe that investors’ understanding of our performance is enhanced by disclosing this performance measure. The adjusted net income measure is an important internal measurement for us. Additionally, we measure our overall performance on this basis in conjunction with other performance metrics. The following are examples of how the adjusted net income measure is utilized:

•senior management receives a monthly analysis of our operating results that is prepared on an adjusted net income basis;

•our annual budgets are prepared on an adjusted net income basis; and

•other goal setting and performance measurements.

Purchase accounting adjustments

Adjusted net income is calculated prior to considering certain significant purchase accounting impacts that result from business combinations and net asset acquisitions. These impacts, primarily associated with the acquisition of Abaxis (acquired in July 2018), the Pharmaq business (acquired in November 2015), certain assets of Abbott Animal Health (acquired in February 2015), King Animal Health (KAH) (acquired in 2011), Fort Dodge Animal Health (FDAH) (acquired in 2009), and Pharmacia Animal Health business (acquired in 2003), include amortization related to the increase in fair value of the acquired finite-lived intangible assets and depreciation related to the increase/decrease to fair value of the acquired fixed assets. Therefore, the adjusted net income measure includes the revenue earned upon the sale of the acquired products without considering the aforementioned significant charges.

36 |

While certain purchase accounting adjustments can occur through 20 or more years, this presentation provides an alternative view of our performance that is used by management to internally assess business performance. We believe the elimination of amortization attributable to acquired intangible assets provides management and investors an alternative view of our business results by providing a degree of parity to internally developed intangible assets for which R&D costs previously have been expensed.

A completely accurate comparison of internally developed intangible assets and acquired intangible assets cannot be achieved through adjusted net income. These components of adjusted net income are derived solely from the impact of the items listed above. We have not factored in the impact of any other differences in experience that might have occurred if we had discovered and developed those intangible assets on our own, and this approach does not intend to be representative of the results that would have occurred in those circumstances. For example, our R&D costs in total, and in the periods presented, may have been different; our speed to commercialization and resulting revenue, if any, may have been different; or our costs to manufacture may have been different. In addition, our marketing efforts may have been received differently by our customers. As such, in total, there can be no assurance that our adjusted net income amounts would have been the same as presented had we discovered and developed the acquired intangible assets.

Acquisition-related costs

Adjusted net income is calculated prior to considering transaction and integration costs associated with significant business combinations or net asset acquisitions because these costs are unique to each transaction and represent costs that were incurred to acquire and integrate certain businesses as a result of the acquisition decision. We have made no adjustments for the resulting synergies.

We believe that viewing income prior to considering these charges provides investors with a useful additional perspective because the significant costs incurred in a business combination result primarily from the need to eliminate duplicate assets, activities or employees––a natural result of acquiring a fully integrated set of activities. For this reason, we believe that the costs incurred to convert disparate systems, to close duplicative facilities or to eliminate duplicate positions (for example, in the context of a business combination) can be viewed differently from those costs incurred in the ordinary course of business.

The integration costs associated with a business combination may occur over several years, with the more significant impacts generally ending within three years of the transaction. Because of the need for certain external approvals for some actions, the span of time needed to achieve certain restructuring and integration activities can be lengthy. For example, due to the regulated nature of the animal health medicines, vaccines and diagnostics business, the closure of excess facilities can take several years, as all manufacturing changes are subject to extensive validation and testing and must be approved by the U.S. Food and Drug Administration and/or other regulatory authorities.

Certain significant items

Adjusted net income is calculated excluding certain significant items. Certain significant items represent substantive, unusual items that are evaluated on an individual basis. Such evaluation considers both the quantitative and the qualitative aspect of their unusual nature. Unusual, in this context, may represent items that are not part of our ongoing business; items that, either as a result of their nature or size, we would not expect to occur as part of our normal business on a regular basis; items that would be nonrecurring; or items that relate to products that we no longer sell. While not all-inclusive, examples of items that could be included as certain significant items would be costs related to a major non-acquisition-related restructuring charge and associated implementation costs for a program that is specific in nature with a defined term, such as those related to our non-acquisition-related cost-reduction and productivity initiatives; amounts related to disposals of products or facilities that do not qualify as discontinued operations as defined by U.S. GAAP; certain intangible asset impairments; adjustments related to the resolution of certain tax positions; significant currency devaluation; the impact of adopting certain significant, event-driven tax legislation; or charges related to legal matters. See Notes to Condensed Consolidated Financial Statements— Note 15. Commitments and Contingencies. Our normal, ongoing defense costs or settlements of and accruals on legal matters made in the normal course of our business would not be considered certain significant items.

*Calculation not meaningful.

(a)    The effective tax rate on adjusted pretax income is 20.0% and 20.5% for the three months ended September 30, 2020 and September 30, 2019, respectively. The lower effective tax rate for the three months ended September 30, 2020, compared with the three months ended September 30, 2019, was primarily attributable to a $4 million and $1 million discrete tax benefit recorded in the three months ended September 30, 2020 and 2019, respectively, related to the excess tax benefits for share-based payments, partially offset by a $3 million discrete tax benefit recorded in the three months ended September 30, 2019 related to changes in other tax items.

The effective tax rate on adjusted pretax income is 19.7% and 19.4% for the nine months ended September 30, 2020 and September 30, 2019, respectively. The higher effective tax rate for the nine months ended September 30, 2020, compared with the nine months ended September 30, 2019, was primarily attributable to (i) changes in the jurisdictional mix of earnings, which includes the impact of the location of earnings as well as repatriation costs, and (ii) an $11 million net discrete tax benefit recorded in the nine months ended September 30, 2019, primarily related to the effective settlement of certain issues with

Analysis of the condensed consolidated statements of comprehensive income

Substantially all changes in other comprehensive income for the periods presented are related to foreign currency translation adjustments. These changes result from the strengthening or weakening of the U.S. dollar as compared to the currencies in the countries in which we do business. The gains and losses associated with these changes are deferred on the balance sheet in Accumulated other comprehensive loss until realized.

Analysis of the condensed consolidated balance sheets

September 30, 2020 vs. December 31, 2019

For a discussion about the changes in Cash and cash equivalents, Short-term borrowings, and Long-term debt, net of discount and issuance costs, see “Analysis of financial condition, liquidity and capital resources” below.

Accounts Receivable, less allowance for doubtful accounts decreased as a result of timing of customer payments and rebate credits issued to customers, lower sales related to seasonality and the impact of foreign exchange.

Inventories increased for a new product launch, lower sales than anticipated for certain products and increases in safety stock levels. See Notes to Condensed Consolidated Financial Statements - Note 10. Inventories.

Other current assets increased primarily as a result of the timing of income tax payments, higher value-added tax receivables for our international markets and other higher prepaid expenses.

Property, plant and equipment less accumulated depreciation increased primarily as a result of capital spending, partially offset by depreciation expense and the impact of foreign currency.

Identifiable intangible assets, less accumulated amortization decreased primarily due to amortization expense and the impact of foreign exchange, partially offset by intangible asset additions from acquisitions. See Notes to Condensed Consolidated Financial Statements - Note 11. Goodwill and Other Intangible Assets.

Accounts payable increased as a result of the timing of payments.

Accrued expenses decreased primarily as a result of the timing of payments for accrued interest and other expenses and customer rebates from the prior period.

Accrued compensation and related items decreased primarily due to payment of 2019 annual bonuses to eligible employees and 2019 employee savings plan contributions, partially offset by the pro rata accrual of similar items for 2020.

The net changes in Noncurrent deferred tax assets, Noncurrent deferred tax liabilities, Income taxes payable and Other taxes payable primarily reflect adjustments to the accrual for the income tax provision, the timing of income tax payments, the tax impact of various acquisitions, the impact of the remeasurement of deferred taxes as a result of changes in tax rates and the integration of acquired businesses.

Other current liabilities and Other noncurrent liabilities increased primarily due to the mark-to-mark adjustment of cross-currency interest rate swaps.

For an analysis of the changes in Total Equity, see the Condensed Consolidated Statements of Equity and Notes to Condensed Consolidated Financial Statements— Note 13. Stockholders' Equity.

*Calculation not meaningful.

Operating activities

Nine months ended September 30, 2020 vs. nine months ended September 30, 2019

Net cash provided by operating activities was $1,408 million for the nine months ended September 30, 2020, and $1,213 million for the nine months ended September 30, 2019. The increase in net income after non-cash adjustments was partially offset by timing of payments in the ordinary course of business.

Investing activities

Nine months ended September 30, 2020 vs. nine months ended September 30, 2019

Our net cash used in investing activities was $395 million for the nine months ended September 30, 2020, compared with net cash used in investing activities of $291 million for the nine months ended September 30, 2019. The net cash used in investing activities for 2020 was primarily due to capital expenditures, acquisitions and net payments for cross-currency interest rate swaps, partially offset by proceeds from the sale of assets, including a contingent payment received pursuant to an agreement related to the 2016 sale of certain U.S. manufacturing sites. The net cash used in investing activities for 2019 was primarily due to capital expenditures and the acquisition of Platinum Performance in the

40 |

third quarter of 2019, partially offset by proceeds from the maturities of debt securities, proceeds from cross-currency interest rate swaps and proceeds received pursuant to an agreement related to the 2016 sale of certain U.S. manufacturing sites.

Financing activities

Nine months ended September 30, 2020 vs. nine months ended September 30, 2019

Our net cash provided by financing activities was $720 million for the nine months ended September 30, 2020, compared with net cash used in financing activities of $701 million for the nine months ended September 30, 2019. The net cash provided by financing activities for 2020 was primarily attributable to the proceeds received from the issuance of senior notes in May 2020 and net proceeds in connection with the issuance of common stock under our equity incentive plan, partially offset by the payment of dividends and the purchase of treasury shares. The net cash used in financing activities for 2019 was primarily attributable to the purchase of treasury shares, the payment of dividends, the payment of short-term borrowings and the payments of contingent consideration related to the 2016 acquisition of certain intangible assets related to our livestock product portfolio and the 2018 acquisition of a manufacturing business in Ireland.

Analysis of financial condition, liquidity and capital resources

While we believe our cash and cash equivalents on hand, our operating cash flows and our existing financing arrangements will be sufficient to support our future cash needs, this may be subject to the environment in which we operate. Risks to our ability to meet future funding requirements include global economic conditions described in the following paragraph.

Global financial markets may be impacted by macroeconomic, business and financial volatility. As markets change, we will continue to monitor our liquidity position, but there can be no assurance that a challenging economic environment or an economic downturn will not impact our liquidity or our ability to obtain future financing.

Selected measures of liquidity and capital resources

Certain relevant measures of our liquidity and capital resources follow:

	September 30,		December 31,
(MILLIONS OF DOLLARS)	2020		2019
Cash and cash equivalents	$	3,654	$	1,934
Accounts receivable, net(a)	1,012		1,086
Current portion of long-term debt	1,100		500
Long-term debt, net of discount and issuance costs	6,595		5,947
Working capital	4,357		2,942
Ratio of current assets to current liabilities	2.82:1		2.63:1

(a)    Accounts receivable are usually collected over a period of 45 to 75 days. For the nine months ended September 30, 2020, compared with December 31, 2019, the number of days that accounts receivables are outstanding remained approximately the same. We regularly monitor our accounts receivable for collectability, particularly in markets where economic conditions remain uncertain. We believe that our allowance for doubtful accounts is appropriate. Our assessment is based on such factors as past due aging, historical and expected collection patterns, the financial condition of our customers, the robust nature of our credit and collection practices and the economic environment.

For additional information about the sources and uses of our funds, see the Analysis of the condensed consolidated balance sheets and Analysis of the condensed consolidated statements of cash flows sections of this MD&A.

Credit facility and other lines of credit

In December 2016, we entered into an amended and restated revolving credit agreement with a syndicate of banks providing for a multi-year $1.0 billion senior unsecured revolving credit facility (the credit facility). In December 2018, the maturity for the amended and restated credit facility was extended through December 2023. Subject to certain conditions, we have the right to increase the credit facility to up to $1.5 billion. The credit facility contains a financial covenant requiring us to not exceed a maximum total leverage ratio (the ratio of consolidated net debt as of the end of the period to consolidated Earnings Before Interest, Income Taxes, Depreciation and Amortization (EBITDA) for such period) of 3.5:1. Upon entering into a material acquisition, the maximum total leverage ratio increases to 4:1, and extends until the fourth full consecutive fiscal quarter ended immediately following the consummation of a material acquisition.

The credit facility also contains a financial covenant requiring that we maintain a minimum interest coverage ratio (the ratio of EBITDA at the end of the period to interest expense for such period) of 3.50:1. In addition, the credit facility contains other customary covenants.

We were in compliance with all financial covenants as of September 30, 2020 and December 31, 2019. There were no amounts drawn under the credit facility as of September 30, 2020 or December 31, 2019.

We have additional lines of credit and other credit arrangements with a group of banks and other financial intermediaries for general corporate purposes. We maintain cash and cash equivalent balances in excess of our outstanding short-term borrowings. As of September 30, 2020, we had access to $77 million of lines of credit which expire at various times through 2020, and are generally renewed annually. There were $1.4 million of borrowings outstanding related to these facilities as of September 30, 2020 and no borrowings outstanding as of December 31, 2019.

Domestic and international short-term funds

Many of our operations are conducted outside the U.S. The amount of funds held in the U.S. will fluctuate due to the timing of receipts and payments in the ordinary course of business and due to other reasons, such as business development activities. As part of our ongoing liquidity assessments, we regularly monitor the mix of U.S. and international cash flows (both inflows and outflows). Actual repatriation of overseas funds can result in additional U.S. and local income taxes, such as U.S. state income taxes, local withholding taxes, and taxes on currency gains and losses.

Global economic conditions

Challenging economic conditions in recent years have not had, nor do we anticipate that it will have, a significant impact on our liquidity. Due to our operating cash flows, financial assets, access to capital markets and available lines of credit and revolving credit agreements, we continue to believe that we have the ability to meet our liquidity needs for the foreseeable future. As markets change, we continue to monitor our liquidity position. There can be no assurance that a challenging economic environment or an economic downturn would not impact our ability to obtain financing in the future.

Debt

On October 13, 2020, we redeemed in full the $500 million aggregate principal amount of our 3.450% 2015 senior notes due 2020 at a redemption price equal to 100% of the principal amount, plus accrued interest to, but not including, the redemption date.

On May 12, 2020, we issued $1.25 billion aggregate principal amount of our senior notes (2020 senior notes), with an original issue discount of $10 million. These notes are comprised of $750 million aggregate principal amount of 2.000% senior notes due 2030 and $500 million aggregate principal amount of 3.000% senior notes due 2050. The net proceeds were used to repay the principal of our 3.450% senior notes due 2020 in the aggregate principal amount of $500 million and the remainder will be used for general corporate purposes.

On August 20, 2018, we issued $1.5 billion aggregate principal amount of our senior notes (2018 senior notes), with an original issue discount of $4 million. On September 12, 2017, we issued $1.25 billion aggregate principal amount of our senior notes (2017 senior notes), with an original issue discount of $7 million. On November 13, 2015, we issued $1.25 billion aggregate principal amount of our senior notes (2015 senior notes), with an original issue discount of $2 million. On January 28, 2013, we issued $3.65 billion aggregate principal amount of our senior notes (2013 senior notes) in a private placement, with an original issue discount of $10 million.

The 2013, 2015, 2017, 2018 and 2020 senior notes are governed by an indenture and supplemental indenture (collectively, the indenture) between us and Deutsche Bank Trust Company Americas, as trustee. The indenture contains certain covenants, including limitations on our and certain of our subsidiaries' ability to incur liens or engage in sale lease-back transactions. The indenture also contains restrictions on our ability to consolidate, merge or sell substantially all of our assets. In addition, the indenture contains other customary terms, including certain events of default, upon the occurrence of which (if not cured or waived), the 2013, 2015, 2017, 2018 and 2020 senior notes may be declared immediately due and payable.

Pursuant to the indenture, we are able to redeem the 2013, 2015, 2017 and 2020 senior notes and the 2018 fixed rate senior notes of any series, in whole or in part, at any time by paying a “make whole” premium, plus accrued and unpaid interest to, but excluding, the date of redemption. The 2018 floating rate senior notes are not redeemable at our option prior to their maturity date. Pursuant to our tax matters agreement with Pfizer, we will not be permitted to redeem the 2013 senior notes due 2023 pursuant to this optional redemption provision, except under limited circumstances. Upon the occurrence of a change of control of us and a downgrade of the 2013, 2015, 2017, 2018 and 2020 senior notes below an investment grade rating by each of Moody's Investors Service, Inc. and Standard & Poor's Ratings Services, we are, in certain circumstances, required to make an offer to repurchase all of the outstanding 2013, 2015, 2017, 2018 and 2020 senior notes at a price equal to 101% of the aggregate principal amount of the 2013, 2015, 2017, 2018 and 2020 senior notes together with accrued and unpaid interest to, but excluding, the date of repurchase.

Credit Ratings

Two major corporate debt-rating organizations, Moody's and S&P, assign ratings to our short-term and long-term debt. A security rating is not a recommendation to buy, sell or hold securities and the rating is subject to revision or withdrawal at any time by the rating organization. Each rating should be evaluated independently of any other rating.

The following table provides the current ratings assigned by these rating agencies to our commercial paper and senior unsecured non-credit-enhanced long-term debt:

	Commercial
	Paper	Long-term Debt		Date of
Name of Rating Agency	Rating	Rating	Outlook	Last Action
Moody’s	P-2	Baa1	Stable	August 2017
S&P	A-2	BBB	Stable	December 2016

Share Repurchase Program

In December 2018, the company's Board of Directors authorized a $2.0 billion share repurchase program. As of September 30, 2020, there was approximately $1.4 billion remaining under this authorization. Purchases of Zoetis shares may be made at the discretion of management, depending on market conditions and business needs. Share repurchases may be executed through various means, including open market or privately negotiated transactions. During the first three months of 2020, approximately 1.8 million shares were repurchased. We temporarily suspended share repurchases beginning in the second quarter of 2020.

Off-balance sheet arrangements

In the ordinary course of business and in connection with the sale of assets and businesses, we may indemnify our counterparties against certain liabilities that may arise in connection with a transaction or that are related to activities prior to a transaction. These indemnifications typically pertain to environmental, tax, employee and/or product-related matters, and patent-infringement claims. If the indemnified party were to make a successful claim pursuant to the terms of the indemnification, we would be required to reimburse the loss. These indemnifications are generally subject to threshold amounts, specified claim periods and other restrictions and limitations. Historically, we have not paid significant amounts under these provisions and, as of September 30, 2020, or December 31, 2019, recorded amounts for the estimated fair value of these indemnifications are not significant.

New accounting standards

Recently Issued Accounting Standards Not Adopted as of September 30, 2020

A description of recently issued accounting standards is contained in Note 3. Accounting Standards of the Notes to Condensed Consolidated Financial Statements.

Forward-looking statements and factors that may affect future results

This report contains “forward-looking” statements. We generally identify forward-looking statements by using words such as “anticipate,” “estimate,” “could,” “expect,” “intend,” “project,” “plan,” “predict,” “believe,” “seek,” “continue,” “outlook,” “objective,” “target,” “may,” “might,” “will,” “should,” “can have,” “likely” or the negative version of these words or comparable words or by using future dates in connection with any discussion of future performance, actions or events.

In particular, forward-looking statements include statements relating to the impact of the COVID-19 pandemic, our 2020 financial guidance, future actions, business plans or prospects, prospective products, product approvals or products under development, product supply disruptions, R&D costs, timing and likelihood of success, future operating or financial performance, future results of current and anticipated products and services, strategies, sales efforts, expenses, production efficiencies, production margins, anticipated timing of generic market entries, integration of acquired businesses, interest rates, tax rates, changes in tax regimes and laws, foreign exchange rates, growth in emerging markets, the outcome of contingencies, such as legal proceedings, plans related to share repurchases and dividends, government regulation and financial results. These statements are not guarantees of future performance, actions or events. Forward-looking statements are subject to risks and uncertainties, many of which are beyond our control, and are based on assumptions that could prove to be inaccurate. Among the factors that could cause actual results to differ materially from past results and future plans and projected future results are the following:

•the impact of the COVID-19 pandemic on our business, suppliers, customers and workforce;

•unanticipated safety, quality or efficacy concerns about our products;

•issues with any of our top products;

•failure of our R&D, acquisition and licensing efforts to generate new products and product lifecycle innovations;

•the possible impact and timing of competing products, including generic alternatives, on our products and our ability to compete against such products;

•disruptive innovations and advances in medical practices and technologies;

•difficulties and delays in the development or commercialization of new products;

•consolidation of our customers and distributors;

•changes in the distribution channel for companion animal products;

•failure to successfully acquire businesses, license rights or products, integrate businesses, form and manage alliances or divest businesses;

•acquiring or implementing new business lines or offering new products and services;

•restrictions and bans on the use of and consumer preferences regarding antibacterials in food-producing animals;

•perceived adverse effects linked to the consumption of food derived from animals that utilize our products or animals generally;

•adverse global economic conditions;

•increased regulation or decreased governmental support relating to the raising, processing or consumption of food-producing animals;

•fluctuations in foreign exchange rates and potential currency controls;

•changes in tax laws and regulations;

•legal factors, including product liability claims, antitrust litigation and governmental investigations, including tax disputes, environmental concerns, commercial disputes and patent disputes with branded and generic competitors, any of which could preclude commercialization of products or negatively affect the profitability of existing products;

•failure to protect our intellectual property rights or to operate our business without infringing the intellectual property rights of others;

•product launch delays, inventory shortages, recalls or unanticipated costs caused by manufacturing problems and capacity imbalances;

•an outbreak of infectious disease carried by animals;

•adverse weather conditions and the availability of natural resources;

•the economic, political, legal and business environment of the foreign jurisdictions in which we do business;

•a cyber-attack, information security breach or other misappropriation of our data;

•quarterly fluctuations in demand and costs;

44 |

•governmental laws and regulations affecting domestic and foreign operations, including without limitation, tax obligations and changes affecting the tax treatment by the U.S. of income earned outside the U.S. that may result from pending and possible future proposals; and

•governmental laws and regulations affecting our interactions with veterinary healthcare providers.

However, there may also be other risks that we are unable to predict at this time. These risks or uncertainties may cause actual results to differ materially from those contemplated by a forward-looking statement. Such risks and uncertainties may be amplified by the COVID-19 pandemic and its impact on the global economy and our business. You should not put undue reliance on forward-looking statements. Forward-looking statements speak only as of the date on which they are made. We undertake no obligation to publicly update forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law or by the rules and regulations of the SEC. You are advised, however, to consult any further disclosures we make on related subjects in our Form 10-Q and 8-K reports and our other filings with the SEC. You should understand that it is not possible to predict or identify all such factors. Consequently, you should not consider the above to be a complete discussion of all potential risks or uncertainties.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

A significant portion of our revenue and costs are exposed to changes in foreign exchange rates. In addition, our outstanding borrowings may be subject to risk from changes in interest rates and foreign exchange rates. The overall objective of our financial risk management program is to seek to minimize the impact of foreign exchange rate movements and interest rate movements on our earnings. We manage these financial exposures through operational means and by using certain financial instruments. These practices may change as economic conditions change.

Foreign exchange risk

Our primary net foreign currency translation exposures are the Australian dollar, Brazilian real, Canadian dollar, Chinese yuan, euro and British pound. We seek to manage our foreign exchange risk, in part, through operational means, including managing same-currency revenue in relation to same-currency costs and same-currency assets in relation to same-currency liabilities.

Foreign exchange risk is also managed through the use of foreign currency forward-exchange contracts. These contracts are used to offset the potential earnings effects from mostly intercompany short-term foreign currency assets and liabilities that arise from operations.

Our financial instrument holdings at September 30, 2020, were analyzed to determine their sensitivity to foreign exchange rate changes. The fair values of these instruments were determined using Level 2 inputs. The sensitivity analysis of changes in the fair value of all foreign currency forward-exchange contracts at September 30, 2020, indicates that if the U.S. dollar were to appreciate against all other currencies by 10%, the fair value of these contracts would increase by $15 million, and if the U.S. dollar were to weaken against all other currencies by 10%, the fair value of these contracts would decrease by $21 million. For additional details, see Notes to Condensed Consolidated Financial Statements— Note 9B. Financial Instruments: Derivative Financial Instruments.

Interest rate risk

Our outstanding debt balances are predominantly fixed rate debt. While changes in interest rates will have no impact on the interest we pay on our fixed rate debt, interest on our $300 million aggregate principal amount of 2018 Floating Rate Senior Notes due 2021, as well as interest on our commercial paper and revolving credit facility will be exposed to interest rate fluctuations. Additionally, as of September 30, 2020, we held certain interest rate swap agreements that have the economic effect of modifying the fixed-interest obligations associated with our 3.900% senior notes due 2028, so that a portion of the fixed-rate interest payable on these senior notes effectively became variable based on LIBOR. At September 30, 2020, there were no commercial paper borrowings outstanding and there was no outstanding principal balance under our revolving credit facility.

By issuing the Floating Rate Notes and by entering into the aforementioned swap arrangements, we have assumed risks associated with variable interest rates based upon LIBOR. Changes in the overall level of interest rates affect the interest expense that we recognize in our Consolidated Statements of Income. An interest rate risk sensitivity analysis is used to measure interest rate risk by computing estimated changes in cash flows as a result of assumed changes in market interest rates. As of September 30, 2020, if LIBOR-based interest rates would have been higher by 100 basis points, the change would have increased our interest expense annually by approximately $4.6 million, as it relates to our fixed to floating interest rate swap agreements and floating-rate borrowings. See Notes to Condensed Consolidated Financial Statements— Note 9. Financial Instruments.

Item 4.    Controls and Procedures

Disclosure Controls and Procedures

An evaluation was carried out under the supervision and with the participation of the company's management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934). Based upon that evaluation as of September 30, 2020, the company's Chief Executive Officer and Chief Financial Officer concluded that the company's disclosure controls and procedures are effective at a reasonable level of assurance in alerting them in a timely manner to material information required to be disclosed in our periodic reports filed with the SEC.

Changes in Internal Control over Financial Reporting

During our most recent fiscal quarter, there has not been any change in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934) that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1.    Legal Proceedings

The information required by this Item is incorporated herein by reference to Notes to Condensed Consolidated Financial Statements—Note 15. Commitments and Contingencies in Part I— Item 1, of this Quarterly Report on Form 10-Q.

Item 1A.     Risk Factors

In addition to the other information set forth in this Form 10-Q, you should carefully consider the factors discussed in the "Our Operating Environment" and "Forward-Looking Statements and Factors That May Affect Future Results" sections of the MD&A and in Part I, Item 1A. "Risk Factors," of our 2019 Annual Report on Form 10-K, which could materially affect our business, financial condition, or future results and which are incorporated by reference herein. Set forth below are updates to certain of the risk factors disclosed in our 2019 Annual Report on Form 10-K.

Risks related to our business and industry

The COVID-19 pandemic has negatively affected the global economy; has disrupted our and our customers', suppliers', and vendors' operations; has significantly affected our business, financial condition, results of operations and cash flows; and may materially adversely affect our business, financial condition, results of operations and/or cash flows.

The novel coronavirus (COVID-19) was identified in China in late 2019 and has spread globally. The World Health Organization declared COVID-19 a global pandemic. The rapid spread has resulted in authorities implementing numerous measures to try to contain the virus, such as travel bans and restrictions, quarantines, shelter in place orders and shutdowns of non-essential businesses. Even though we are currently designated as an essential business and have continued physical operations with respect to manufacturing and supply chain globally, these measures have impacted and may further impact all or portions of our workforce and operations, the operations and workforce of our customers, and those of our respective vendors and suppliers. There is no certainty that measures taken by governmental authorities will be sufficient to mitigate the risks posed by the virus, and our ability to continue to perform critical functions could be harmed.

We, and the contract manufacturing organizations (CMOs) we work with, have significant manufacturing operations throughout the world, and most, if not all, of the countries where they are located have been affected by the pandemic and have taken measures to try to contain it. There is considerable uncertainty regarding such measures and potential future measures. In particular, we, and the CMOs we work with, could be asked or ordered to perform certain activities for human health that would divert significant manufacturing and other resources away from our business. Such human health activities could also expose us to additional liability. Future restrictions on our access to or control over our manufacturing facilities or on our support operations or workforce, or similar limitations on our vendors or suppliers, and restrictions or disruptions of transportation, such as reduced availability of air transport, port closures and increased border controls or closures, or export bans could limit our ability to meet customer demand and have a material adverse effect on our business, financial condition, results of operations and/or cash flows.

The COVID-19 pandemic also has and may continue to reduce demand for our products as a result of the negative impact it has had and may continue to have on our livestock and companion animal customers. Our livestock customers have been and may continue to be challenged by voluntary or mandatory facility closures, reduced packing plant capacity, travel bans and quarantines inhibiting consumption of protein and transportation of live animals, and labor shortages negatively impacting their operations. For example, a number of significant meat processing plants have closed temporarily in recent months after employees tested positive for COVID-19. In addition, despite recent increases in telemedicine, our companion animal customers’ businesses have been and may continue to be negatively impacted by reduced demand for their veterinary services. The resulting reduction in demand for our products, has had a significant adverse effect on our business, financial condition, results of operations and cash flows and may have a material adverse effect on our business, financial condition, results of operations and/or cash flows, particularly if such demand reduction is prolonged.

Moreover, measures imposed by governments and other authorities to try to contain the COVID-19 pandemic, such as travel bans, quarantines and restrictions on veterinary services, may impede the ability of our R&D organization to complete clinical studies required to register new products in the manner and on the timeline we anticipate. If such measures become increasingly restrictive in nature, current and future product approvals may be delayed, which could have a material adverse effect on our business, financial condition, results of operations and/or cash flows.

The COVID-19 pandemic has also significantly increased economic and demand uncertainty and has led to disruption and volatility in the global capital markets, which could increase the cost of capital and adversely impact access to capital. The economic impact of the ongoing COVID-19 pandemic has resulted in a global recession that may continue for an unknown period of time. In order to preserve liquidity, we issued debt securities in May 2020 and we may incur additional indebtedness, whether through the issuance of debt securities, drawdowns under our credit facility or otherwise in the future. An increase in our outstanding indebtedness will result in additional interest expense. We may also seek to conserve cash by reducing or canceling future dividends or delaying capital expenditures. Risks related to negative economic conditions are described in our risk factor titled "Our business is subject to risk based on global economic conditions" under “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2019.

Additionally, many of our workforce are currently working remotely as a result of the pandemic. An extended period of remote work arrangements could introduce operational risks, including, but not limited to, risks associated with information technology and systems, including service interruptions, misappropriation of data, or breaches of security, any of which could have a material adverse effect on our

47 |

business. Working outside of the typical work environment may also introduce additional complexity or inefficiency into our normal processes for key areas like the preparation of financial statements or marketing and sales, which could negatively impact our business.

The ultimate magnitude of the COVID-19 pandemic, including the extent of its impact on our financial and operational results, which has been significant, and may be material, will be determined by the length of time that the pandemic continues (including any relapse or resurgence), its effect on the demand for our products and services, particularly due to impacts on our downstream customers, and on our supply chain, as well as the effect of governmental regulations imposed in response to the pandemic. We cannot at this time predict the full impact of the COVID-19 pandemic, but we anticipate that the COVID-19 pandemic is likely to have a significant impact on our business, financial condition, results of operations and/or cash flows for the remainder of 2020. In addition, actions we have taken or may take, or decisions we have made or may make, as a consequence of the COVID-19 pandemic, including as part of the reopening process, may also result in legal claims or litigation against us. The impact of the COVID-19 pandemic may also exacerbate other risks discussed in the Risk Factors section of our Annual Report on Form 10-K for the year ended December 31, 2019, any of which could have a material effect on us. This situation is changing rapidly and additional impacts may arise that we are not aware of currently.

Generic and other products may be viewed as more cost-effective than our products.

We face competition from products produced by other companies, including generic alternatives to our products. We depend on patents and regulatory data exclusivity periods to provide us with exclusive marketing rights for some of our products. Patents for individual products expire at different times based on the date of the patent filing (or sometimes the date of patent grant) and the legal term of patents in the countries where such patents are obtained. The extent of protection afforded by our patents varies from country to country and is limited by the scope of the claimed subject matter of our patents, the term of the patent and the availability and enforcement of legal remedies in the applicable country. As a result, we face competition from lower-priced generic alternatives to many of our products that no longer have patent protection. In certain circumstances, we have been forced to lower our prices and provide discounts or rebates in order to compete with generic products. Generic competitors are becoming more aggressive in terms of launching at risk before patent rights expire and, because of their pricing, are an increasing percentage of overall animal health sales in certain regions. For example, several companies have launched generic versions of our Rimadyl® chewable product. As a result of generic and other competition, sales of our Rimadyl chewable product in the U.S. have declined by approximately 24% in the years since their introduction. Sales of our Clavamox® products in the U.S. also continue to be negatively impacted by generic competition.

Although the impact of generic competition in the animal health industry to date has not typically mirrored that seen in human health, in certain markets, the impact of generic competition in the future may more closely mirror human health as a result of changes in industry dynamics, such as channel expansion, customer consolidation, an increase in the availability and use of pet insurance and the potential for generic competition by established animal health businesses. If animal health customers increase their use of new or existing generic products, our operating results and financial condition could be materially adversely affected.

Over the next few years, several of our products' patents will expire. Draxxin®, containing the active ingredient tulathromycin, is covered by formulation patents in the U.S., Europe, Canada, Australia and other key markets, with terms that expire between November 2020 and February 2021 in the U.S., Europe, Canada and Australia. The active ingredient tulathromycin is protected in Japan until 2023. Generic tulathromycin products are marketed in certain countries including Colombia, Vietnam, Belarus, Russia, Poland and Croatia. Marketing authorizations for generic tulathromycin products have been granted in Europe, Canada and Australia. There are pending marketing authorizations for generic tulathromycin products in Australia and additional authorizations may be granted in various markets in the future. A generic of Draxxin 25mg/ml has entered the market in Europe. At this time, market entry by generic tulathromycin products in the U.S. is not anticipated before February 2021. Several patents covering the ceftiofur antibiotic product line (Excede®) began expiring in the U.S. in 2015. However, various formulation and use patents relevant to the product line extend through to 2024. Generic versions of Excede have entered the market in Mexico. At this time, the market entry of a generic version of Excede in the U.S. is not anticipated before 2024. The compound patent for selamectin, the active ingredient in our parasiticides Revolution® and Stronghold®, expired in 2014. Formulation patents covering these products expired in important markets in 2019. Generic versions of selamectin are now marketed in markets including the U.S., Europe, Australia and Canada. Draxxin, Revolution/Stronghold, and the ceftiofur product line contributed approximately 16% of our revenue in 2019. In addition, the patent for the active ingredient of Convenia® has expired, however, there are formulation patents relevant to the product line which expire between November 2022 and October 2023. The patent for the active ingredient of Cerenia® has expired; however, there are formulation patents relevant to the product line which expire between May 2020 and January 2027. A generic version of Cerenia has been registered in Europe and is marketed in the European Union, and there is a pending registration in Canada. At this time, there is no indication of market entry of a generic version of Cerenia in the U.S. The formulation patent covering ProHeart® 12 expired in the U.S. in 2019, but expires in Australia, Canada and Japan in October 2021. Zoetis typically enforces its patents whenever appropriate both within and outside the U.S., including by filing infringement claims against other parties.

Risks related to tax matters

The Company could be subject to changes in its tax rates, the adoption of new U.S. or foreign tax legislation or exposure to additional tax liabilities.

The multinational nature of our business subjects us to taxation in the U.S. and numerous foreign jurisdictions. Due to economic and political conditions, tax rates in various jurisdictions may be subject to significant change. The company’s future effective tax rates could be affected by changes in the mix of earnings in countries with differing statutory tax rates, changes in the valuation of deferred tax assets and liabilities, or changes in tax laws or their interpretation.

For example, on October 12, 2020, the Organisation for Economic Co-operation and Development (OECD) published a package of reports, known as the Blueprints, which provide technical details about a two-pillar approach to address the tax challenges of the digital economy. Pillar

48 |

One would amend profit allocation and nexus rules to grant more taxing rights to countries where consumers are located regardless of the physical presence of the business. Pillar Two introduces common global minimum tax rules across the countries participating in the OECD Inclusive Framework. Such rules would operate through top-up taxes and other measures if a multinational group’s income is not subject to a sufficient level of tax in particular jurisdictions. These two proposals combined may represent a significant change in the international tax regime. These proposals require unanimous consent and are currently in a “public comment” period. There is risk of an adverse impact to our effective tax rate as a result of these proposals, but the amount of such impact remains uncertain at this time.

If a new administration were to be elected in the 2020 U.S. presidential and congressional elections, comprehensive tax reform may be high on the agenda which may have an adverse impact to our effective tax rate. At this time, we are properly reflecting the provision for taxes on income using all current enacted global tax laws in every jurisdiction in which we operate.

On March 29, 2017, the U.K. formally notified the European Council of the U.K.’s intention to withdraw from the European Union, commonly referred to as “Brexit”, under Article 50 of the Treaty of Lisbon. On January 23, 2020, the U.K. government approved the Withdrawal Agreement Bill pursuant to which the U.K. exited the EU on January 31, 2020, subject to a transition period of 11 months that commenced on January 31, 2020 for trade and relationship negotiations between the U.K. and the EU. At this time, the impact of Brexit to our effective tax rate remains uncertain.

In addition, our effective tax rate is subject to potential risks that various taxing authorities may challenge the pricing of our cross-border arrangements and subject us to additional tax, adversely impacting our effective tax rate and our tax liability. The company is also subject to the examination of its tax returns and other tax matters by the Internal Revenue Service and other tax authorities and governmental bodies. The company regularly assesses the likelihood of an adverse outcome resulting from these examinations to determine the adequacy of its provision for taxes. There can be no assurance as to the outcome of these examinations. If the company’s effective tax rates were to increase, particularly in the U.S. or other material foreign jurisdictions, or if the ultimate determination of the company’s taxes owed is for an amount in excess of amounts previously accrued, the company’s operating results, cash flows and financial condition could be adversely affected.

Risks related to our indebtedness

We have substantial indebtedness.

We have a significant amount of indebtedness, which could materially adversely affect our operating results, financial condition and liquidity. As of October 31, 2020, we had approximately $7.25 billion of total unsecured indebtedness outstanding. In addition, we currently have agreements for a multi-year revolving credit facility and a commercial paper program, each with a capacity of up to $1.0 billion. While we currently do not have any amounts drawn under the credit facility nor any commercial paper issued under the commercial paper program, we may incur indebtedness under these arrangements in the future.

We may incur substantial additional debt from time to time to finance working capital, capital expenditures, investments or acquisitions, or for other purposes. If we do so, the risks related to our high level of debt could intensify. Specifically, our high level of debt could have important consequences, including:

•making it more difficult for us to satisfy our obligations with respect to our debt;

•limiting our ability to obtain additional financing to fund future working capital, capital expenditures, business development or other general corporate requirements, including dividends;

•increasing our vulnerability to general adverse economic and industry conditions;

•exposing us to the risk of increased interest rates as certain of our borrowings are and may in the future be at variable rates of interest;

•limiting our flexibility in planning for and reacting to changes in the animal health industry;

•placing us at a competitive disadvantage to other, less leveraged competitors;

•impacting our effective tax rate; and

•increasing our cost of borrowing.

In addition, the instruments governing our indebtedness contain restrictive covenants that will limit our ability to engage in activities that may be in our long-term best interest. For example, our credit facility contains a financial covenant requiring us to not exceed a maximum total leverage ratio and covenants that, among other things, limit or restrict our and our subsidiaries' ability, subject to certain exceptions, to incur liens, merge, consolidate or sell, transfer or lease assets, transact with affiliates and incur priority indebtedness. Our failure to comply with such covenants could result in an event of default which, if not cured or waived, could result in the acceleration of all our debt.

We also have outstanding floating rate notes due 2021 (2021 floating rate notes) that have their interest rate calculated quarterly using three-month LIBOR. In addition, we hold certain interest rate swap agreements that have the economic effect of modifying the fixed interest obligations associated with our senior notes due 2028 so that a portion of the interest payable on these notes is effectively variable based on LIBOR. The U.K. Financial Conduct Authority (FCA), which regulates LIBOR, announced that the FCA will no longer persuade or compel banks to submit rates for the calculation of LIBOR after 2021, and it appears likely that LIBOR will be discontinued or modified by 2021. In addition, the U.S. Federal Reserve, in conjunction with the Alternative Reference Rates Committee, a steering committee comprised of large U.S. financial institutions, is considering replacing U.S. dollar LIBOR with the Secured Overnight Financing Rate (SOFR), a new index calculated by short-term repurchase agreements backed by Treasury securities. Although there have been certain issuances utilizing SOFR, it is unknown whether this or any other alternative reference rate will attain market acceptance as a replacement for LIBOR. The discontinuance or modification of LIBOR, the introduction of alternative reference rates or other reforms to LIBOR could cause the interest rate calculated on our 2021 floating rate notes and the interest rate swap agreements associated with our senior notes due 2028 to be materially different than expected.

49 |

In addition, if interest rates in general continue to rise, our interest expense related to the 2021 floating rate notes and the interest rate swap agreements will increase.

Basis of Presentation

2. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements were prepared following the requirements of the Securities and Exchange Commission (SEC) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by accounting principles generally accepted in the United States of America (U.S. GAAP) can be condensed or omitted. Balance sheet amounts and operating results for subsidiaries operating outside the U.S. are as of and for the nine-month periods ended August 31, 2020 and August 31, 2019.

Revenue, expenses, assets and liabilities can vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be representative of those for the full year.

Certain reclassifications of prior year information have been made to conform to the current year's presentation.

We are responsible for the unaudited condensed consolidated financial statements included in this Form 10-Q. The condensed consolidated financial statements include all normal and recurring adjustments that are considered necessary for the fair presentation of our financial position and operating results. The information included in this interim report should be read in conjunction with the financial statements and accompanying notes included in our 2019 Annual Report on Form 10-K.

Accounting Standards

3. Accounting Standards

Recently Adopted Accounting Standards

In August 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Topic 350-40), an accounting standards update which expands the scope of costs associated with cloud computing arrangements that must be capitalized. Under the new guidance, costs associated with implementing a cloud computing arrangement that is a service contract must be capitalized and expensed over the term of the hosting arrangement. We adopted this guidance as of January 1, 2020, the required effective date, on a prospective basis. The adoption did not have a significant impact on our consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments (Topic 326), an accounting standards update which requires an entity to measure and recognize expected credit losses for certain financial instruments, including trade receivables, as an allowance that reflects the entity's current estimate of credit losses expected to be incurred. For available-for-sale debt securities with unrealized losses, the standard requires allowances to be recorded instead of reducing the amortized cost of the investment. We adopted this guidance as of January 1, 2020, the required effective date, on a prospective basis. The adoption did not have a significant impact on our consolidated financial statements.

Recently Issued Accounting Standards

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The new guidance provides temporary optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued because of reference rate reform. Adoption of the provisions of ASU 2020-04 is optional and effective as of March 12, 2020, but is only available through December 31, 2022. We are currently evaluating the impact that the new guidance will have on our consolidated financial statements and related disclosures, as well as the timing of the potential adoption.

4. Revenue

A. Revenue from Product Sales

We offer a diversified portfolio of products which allows us to capitalize on local and regional customer needs. Generally, our products are promoted to veterinarians and livestock producers by our sales organization which includes sales representatives and technical and veterinary operations specialists, and then sold directly by us or through distributors, retailers and e-commerce outlets. The depth of our product portfolio enables us to address the varying needs of customers in different species and geographies. Many of our top selling product lines are distributed

across both of our operating segments, leveraging our research and development (R&D) operations and manufacturing and supply chain network.

Over the course of our history, we have focused on developing a diverse portfolio of animal health products, including medicines, vaccines and diagnostics, complemented by biodevices, genetic tests and a range of services. We refer to a single product in all brands, or its dosage forms for all species, as a product line. We have approximately 300 comprehensive product lines, including products for both livestock and companion animals across each of our major product categories.

In the fourth quarter of 2019, the company modified the list of major product categories to include a category for dermatology products, which was previously included within other pharmaceutical products. The prior period presentation has been revised to reflect the new product categories.

Our major product categories are:

•vaccines: biological preparations that help prevent diseases of the respiratory, gastrointestinal and reproductive tracts or induce a specific immune response;

•anti-infectives: products that prevent, kill or slow the growth of bacteria, fungi or protozoa;

•parasiticides: products that prevent or eliminate external and internal parasites such as fleas, ticks and worms;

•dermatology products: products that relieve itch associated with allergic conditions and atopic dermatitis;

•other pharmaceutical products: pain and sedation, antiemetic, reproductive, and oncology products;

•medicated feed additives: products added to animal feed that provide medicines to livestock; and

•animal health diagnostics: portable blood and urine analysis systems and point-of-care diagnostic products, including instruments and reagents, rapid immunoassay tests, reference laboratory kits and blood glucose monitors.

Our remaining revenue is derived from other non-pharmaceutical product categories, such as nutritionals and agribusiness, as well as products and services in smaller but fast growing areas, including biodevices, genetic tests and precision livestock farming.

Our livestock products primarily help prevent or treat diseases and conditions to enable the cost-effective production of safe, high-quality animal protein. Human population growth and increasing standards of living are important long-term growth drivers for our livestock products in three major ways. First, population growth and increasing standards of living drive increased demand for improved nutrition, particularly animal protein. Second, population growth leads to increased natural resource constraints driving a need for enhanced productivity. Finally, as standards of living improve, there is increased focus on food quality and safety.

Our companion animal products help extend and improve the quality of life for pets; increase convenience and compliance for pet owners; and help veterinarians improve the quality of their care and the efficiency of their businesses. Growth in the companion animal medicines, vaccines and diagnostics sector is driven by economic development, related increases in disposable income and increases in pet ownership and spending on pet care. Companion animals are also living longer, receiving increased medical treatment and benefiting from advances in animal health medicines and vaccines.

The following tables present our revenue disaggregated by geographic area, species, and major product category:

Restructuring Charges and Other Costs Associated with Acquisitions and Cost-Reduction/Productivity Initiatives

6. Restructuring Charges and Other Costs Associated with Acquisitions, Cost-Reduction and Productivity Initiatives

In connection with our cost-reduction/productivity initiatives, we typically incur costs and charges associated with site closings and other facility rationalization actions, workforce reductions and the expansion of shared services, including the development of global systems. In connection with our acquisition activity, we typically incur costs and charges associated with executing the transactions, integrating the acquired operations, which may include expenditures for consulting and the integration of systems and processes, product transfers and restructuring the consolidated company, which may include charges related to employees, assets and activities that will not continue in the consolidated company. All operating functions can be impacted by these actions, including sales and marketing, manufacturing and R&D, as well as functions such as information technology, shared services and corporate operations.

The components of costs incurred in connection with restructuring initiatives, acquisitions and cost-reduction/productivity initiatives are as follows:

Income Tax Disclosure [Abstract]

Income Taxes

8. Income Taxes

A. Taxes on Income

Our effective tax rate was 19.8% for the three months ended September 30, 2020, compared with 18.0% for the three months ended September 30, 2019. The higher effective tax rate for the three months ended September 30, 2020, was primarily attributable to:

•a $14 million net discrete tax benefit recorded in the three months ended September 30, 2019, due to a change in tax basis related to purchase accounting,

partially offset by:

•a $4 million and $1 million discrete tax benefit recorded in the three months ended September 30, 2020 and 2019, respectively, related to the excess tax benefits for share-based payments.

Our effective tax rate was 18.9% for the nine months ended September 30, 2020, compared with 18.2% for the nine months ended September 30, 2019. The higher effective tax rate for the nine months ended September 30, 2020, was primarily attributable to:

•changes in the jurisdictional mix of earnings, which includes the impact of the location of earnings from operations and repatriation costs. The jurisdictional mix of earnings can vary as a result of repatriation decisions, operating fluctuations in the normal course of business and the impact of non-deductible items;

•a $19 million net discrete tax benefit recorded in the nine months ended September 30, 2019, primarily related to the effective settlement of certain issues with non-U.S. tax authorities and a prior period tax adjustment; and

•a $14 million net discrete deferred tax benefit recorded in the nine months ended September 30, 2019, due to a change in tax basis related to purchase accounting,

partially offset by:

•a $29 million and $17 million discrete tax benefit recorded in the nine months ended September 30, 2020 and 2019, respectively, related to the excess tax benefits for share-based payments;

•a $7 million discrete tax benefit recorded in the nine months ended September 30, 2020 related to a remeasurement of deferred taxes resulting from the integration of acquired businesses; and

•a $4 million and $3 million discrete tax benefit recorded in the nine months ended September 30, 2020 and 2019, respectively, related to a remeasurement of deferred taxes as a result of a change in non-U.S. statutory tax rates.

B. Deferred Taxes

As of September 30, 2020, the total net deferred income tax liability of $313 million is included in Noncurrent deferred tax assets ($97 million) and Noncurrent deferred tax liabilities ($410 million).

As of December 31, 2019, the total net deferred income tax liability of $346 million is included in Noncurrent deferred tax assets ($88 million) and Noncurrent deferred tax liabilities ($434 million).

C. Tax Contingencies

As of September 30, 2020, the net tax liabilities associated with uncertain tax positions of $192 million (exclusive of interest and penalties related to uncertain tax positions of $14 million) are included in Noncurrent deferred tax assets and Other noncurrent assets ($2 million) and Other taxes payable ($190 million).

As of December 31, 2019, the net tax liabilities associated with uncertain tax positions of $182 million (exclusive of interest and penalties related to uncertain tax positions of $12 million) are included in Noncurrent deferred tax assets and Other noncurrent assets ($2 million) and Other taxes payable ($180 million).

Our tax liabilities for uncertain tax positions relate primarily to issues common among multinational corporations. Any settlements or statute of limitations expirations could result in a significant decrease in our uncertain tax positions. Substantially all of these unrecognized tax benefits, if recognized, would impact our effective income tax rate. We do not expect that within the next twelve months any of our uncertain tax positions could significantly decrease as a result of settlements with taxing authorities or the expiration of the statutes of limitations. Our assessments are based on estimates and assumptions that have been deemed reasonable by management, but our estimates of uncertain tax positions and potential tax benefits may not be representative of actual outcomes, and any variation from such estimates could materially affect our financial statements in the period of settlement or when the statutes of limitations expire, as we treat these events as discrete items in the period of resolution. Finalizing audits with the relevant taxing authorities can include formal administrative and legal proceedings, and, as a result, it is difficult to estimate the timing and range of possible changes related to our uncertain tax positions, and such changes could be significant.

9. Financial Instruments

A. Debt

Credit Facilities

In December 2016, we entered into an amended and restated revolving credit agreement with a syndicate of banks providing for a multi-year $1.0 billion senior unsecured revolving credit facility (the credit facility). In December 2018, the maturity for the amended and restated revolving credit agreement was extended through December 2023. Subject to certain conditions, we have the right to increase the credit facility to up to $1.5 billion. The credit facility contains a financial covenant requiring us to not exceed a maximum total leverage ratio (the ratio of consolidated net debt as of the end of the period to consolidated Earnings Before Interest, Income Taxes, Depreciation and Amortization (EBITDA) for such period) of 3.50:1. Upon entering into a material acquisition, the maximum total leverage ratio increases to 4.00:1, and extends until the fourth full consecutive fiscal quarter ended immediately following the consummation of a material acquisition.

The credit facility also contains a financial covenant requiring that we maintain a minimum interest coverage ratio (the ratio of EBITDA at the end of the period to interest expense for such period) of 3.50:1. In addition, the credit facility contains other customary covenants.

We were in compliance with all financial covenants as of September 30, 2020, and December 31, 2019. There were no amounts drawn under the credit facility as of September 30, 2020 or December 31, 2019.

We have additional lines of credit and other credit arrangements with a group of banks and other financial intermediaries for general corporate purposes. We maintain cash and cash equivalent balances in excess of our outstanding short-term borrowings. As of September 30, 2020, we had access to $77 million of lines of credit which expire at various times through 2020 and are generally renewed annually. There were $1.4 million of borrowings outstanding related to these facilities as of September 30, 2020 and no borrowings outstanding as of December 31, 2019.

Commercial Paper Program

In February 2013, we entered into a commercial paper program with a capacity of up to $1.0 billion. As of September 30, 2020 and December 31, 2019, there was no commercial paper outstanding under this program.

Senior Notes and Other Long-Term Debt

On May 12, 2020, we issued $1.25 billion aggregate principal amount of our senior notes (2020 senior notes), with an original issue discount of $10 million. These notes are comprised of $750 million aggregate principal amount of 2.000% senior notes due 2030 and $500 million aggregate principal amount of 3.000% senior notes due 2050. The net proceeds were to be used to repay the principal of our 3.450% senior notes due 2020 in the aggregate principal amount of $500 million and the remainder will be used for general corporate purposes. On October 13, 2020, we redeemed in full the $500 million aggregate principal amount of our 3.450% 2015 senior notes due 2020. For additional information, see Note 17 - Subsequent Events.

On August 20, 2018, we issued $1.5 billion aggregate principal amount of our senior notes (2018 senior notes), with an original issue discount of $4 million. On September 12, 2017, we issued $1.25 billion aggregate principal amount of our senior notes (2017 senior notes), with an original issue discount of $7 million. On November 13, 2015, we issued $1.25 billion aggregate principal amount of our senior notes (2015 senior notes), with an original issue discount of $2 million. On January 28, 2013, we issued $3.65 billion aggregate principal amount of our senior notes (2013 senior notes) in a private placement, with an original issue discount of $10 million.

The 2013, 2015, 2017, 2018 and 2020 senior notes are governed by an indenture and supplemental indenture (collectively, the indenture) between us and Deutsche Bank Trust Company Americas, as trustee. The indenture contains certain covenants, including limitations on our and certain of our subsidiaries' ability to incur liens or engage in sale-leaseback transactions. The indenture also contains restrictions on our ability to consolidate, merge or sell substantially all of our assets. In addition, the indenture contains other customary terms, including certain events of default, upon the occurrence of which the 2013, 2015, 2017, 2018 and 2020 senior notes may be declared immediately due and payable.

Pursuant to the indenture, we are able to redeem the 2013, 2015, 2017 and 2020 senior notes and the 2018 fixed rate senior notes or any series, in whole or in part, at any time by paying a “make whole” premium, plus accrued and unpaid interest to, but excluding, the date of redemption. The 2018 floating rate senior notes are not redeemable at our option prior to their maturity date. Pursuant to our tax matters agreement with Pfizer, we will not be permitted to redeem the 2013 senior notes due 2023 pursuant to this optional redemption provision, except under limited circumstances. Upon the occurrence of a change of control of us and a downgrade of the 2013, 2015, 2017, 2018 and 2020 senior notes below an investment grade rating by each of Moody's Investors Service, Inc. and Standard & Poor's Ratings Services, we are, in certain circumstances,

required to make an offer to repurchase all of the outstanding 2013, 2015, 2017, 2018 and 2020 senior notes at a price equal to 101% of the aggregate principal amount of the 2013, 2015, 2017, 2018 and 2020 senior notes together with accrued and unpaid interest to, but excluding, the date of repurchase.

Interest expense, net of capitalized interest, was $62 million and $173 million for the three and nine months ended September 30, 2020, respectively, and $56 million and $167 million for the three and nine months ended September 30, 2019, respectively. Capitalized interest expense was $4 million and $12 million for the three and nine months ended September 30, 2020, respectively, and $3 million and $9 million for the three and nine months ended September 30, 2019, respectively.

B. Derivative Financial Instruments

Foreign Exchange Risk

A significant portion of our revenue, earnings and net investment in foreign affiliates is exposed to changes in foreign exchange rates. We seek to manage our foreign exchange risk, in part, through operational means, including managing same-currency revenue in relation to same-currency costs and same-currency assets in relation to same-currency liabilities. Depending on market conditions, foreign exchange risk is also managed through the use of various derivative financial instruments. These derivative financial instruments serve to manage the exposure of our net investment in certain foreign operations to changes in foreign exchange rates and protect net income against the impact of translation into U.S. dollars of certain foreign exchange-denominated transactions.

All derivative financial instruments used to manage foreign currency risk are measured at fair value and are reported as assets or liabilities on the condensed consolidated balance sheet. The derivative financial instruments primarily offset exposures in the Australian dollar, British pound, Canadian dollar, Chinese yuan, euro, and Japanese yen. Changes in fair value are reported in earnings or in Accumulated other comprehensive income/(loss), depending on the nature and purpose of the financial instrument, as follows:

•For foreign exchange contracts not designated as hedging instruments, we recognize the gains and losses on forward-exchange contracts that are used to offset the same foreign currency assets or liabilities immediately into earnings along with the earnings impact of the items they generally offset. These contracts essentially take the opposite currency position of that reflected in the month-end balance sheet to counterbalance the effect of any currency movement. The vast majority of the foreign exchange derivative financial instruments mature within 60 days and all mature within three years.

•For cross-currency interest rate swaps, which are designated as a hedge against our net investment in foreign operations, changes in the fair value are recorded as a component of cumulative translation adjustment within Accumulated other comprehensive income/

(loss) and reclassified into earnings when the foreign investment is sold or substantially liquidated. Gains and losses excluded from the assessment of hedge effectiveness are recognized in earnings (Interest expense—net of capitalized interest). The cash flows from these contracts are reflected within the investing section of our Condensed Consolidated Statement of Cash Flows. The cross-currency interest rate swap contracts have varying maturities of up to five years.

The company may use interest rate swap contracts on certain investing and borrowing transactions to manage its net exposure to interest rates and to reduce its overall cost of borrowing.

•During the second quarter of 2020, we entered into treasury lock trades with an aggregate notional value of $600 million. We designated these treasury locks as cash flow hedges against interest rate exposure related to the issuance of fixed-rate debt in the second quarter of 2020. Of the aggregate notional value of $600 million, four treasury locks with a total notional amount of $425 million were designated as hedges against the ten-year fixed rate debt maturing in 2030, and two treasury locks with a total notional amount of $175 million were designated as hedges against the thirty-year note maturing in 2050. Upon issuance of our 2020 senior notes, we terminated the treasury locks and paid $6 million in cash to the counterparties for settlement. The settlement amount, which represents the fair value of the contracts at the time of termination, was recorded in Accumulated other comprehensive loss, and will be amortized into income over the life of the 2020 senior notes.

•In anticipation of issuing fixed-rate debt, we may use forward-starting interest rate swaps that are designated as cash flow hedges to hedge against changes in interest rates that could impact expected future issuances of debt. Unrealized gains or losses on the forward-starting interest rate swaps are reported in Accumulated other comprehensive loss and are recognized in earnings over the life of the future fixed-rate notes. When the company discontinues hedge accounting because it is no longer probable that an anticipated transaction will occur within the originally expected period of execution, or within an additional two-month period thereafter, changes to fair value accumulated in other comprehensive income are recognized immediately in earnings. For the nine months ended September 30, 2020, we entered into forward-starting interest rate swaps, having an effective date and mandatory termination date in March 2023, to hedge against interest rate exposure related principally to the anticipated future issuance of fixed-rate debt to be used primarily to refinance our 3.250% 2013 senior notes due 2023, and a forward-starting interest rate swap, having an effective date and mandatory termination date in March 2026, to hedge against interest rate exposure related principally to the anticipated future issuance of fixed-rate debt to be used primarily to refinance our 4.500% senior notes due 2025.

•We may use fixed-to-floating interest rate swaps that are designated as fair value hedges to hedge against changes in the fair value of certain fixed-rate debt attributable to changes in the benchmark LIBOR rate. These derivative instruments effectively convert a portion of the company’s long-term debt from fixed rate to floating rate debt based on three-month LIBOR plus a spread. Gains or losses on the fixed-to-floating interest rate swaps due to changes in LIBOR are recorded in Interest expense, net of capitalized interest. Changes in the fair value of the fixed-to-floating interest rate swaps are offset by changes in the fair value of the underlying fixed rate debt. As of September 30, 2020, we had an outstanding fixed-to-floating interest rate swap that corresponds to a portion of the 3.900% 2018 senior notes due 2028. The amounts recorded during the three and nine months ended September 30, 2020 for changes in the fair value of this hedge are not material to our consolidated financial statements.

The company’s cross-currency interest rate swaps are subject to master netting arrangements to mitigate credit risk by permitting net settlement of transactions with the same counterparty. We may also enter into collateral security arrangements with certain of our counterparties to exchange cash collateral when the net fair value of certain derivative instruments fluctuates from contractually established thresholds. At September 30, 2020, there was $16 million of collateral received related to the long-term cross-currency interest rate swaps recorded in Other noncurrent assets.

We use a market approach in valuing financial instruments on a recurring basis. Our derivative financial instruments are measured at fair value on a recurring basis using Level 2 inputs in the calculation of fair value.

The amounts of net gains on derivative instruments not designated as hedging instruments, recorded in Other (income)/deductions—net, are as follows:

Share-Based Payments

12. Share-based Payments

The Zoetis 2013 Equity and Incentive Plan (the Equity Plan) provides long-term incentives to our employees and non-employee directors. The principal types of share-based awards available under the Equity Plan may include, but are not limited to, stock options, restricted stock and restricted stock units (RSUs), deferred stock units (DSUs), performance-vesting restricted stock units (PSUs) and other equity-based or cash-based awards.

The components of share-based compensation expense are as follows:

	Three Months Ended				Nine Months Ended

Share-based compensation expense—total(c)	$	14	$	16	$	46	$	51

(a) For the three and nine months ended September 30, 2019, includes share-based compensation expense of $4 million and $13 million, respectively related to the acquisition of Abaxis, for the post-merger service period.

(b)     Includes additional share-based compensation expense as a result of accelerated vesting of outstanding RSUs of terminated employees in connection with the acquisition of Abaxis, for the three and nine months ended September 30, 2019 of approximately $1 million and $5 million, respectively, which is included in Restructuring charges and certain acquisition-related costs.

(c)     Amounts capitalized to inventory were insignificant for the three and nine months ended September 30, 2020 and three months ended September 30, 2019 and $1 million for the nine months ended September 30, 2019.

During the nine months ended September 30, 2020, the company granted 292,727 stock options with a weighted-average exercise price of $143.23 per stock option and a weighted-average fair value of $33.83 per stock option. The fair-value based method for valuing each Zoetis stock option grant on the grant date uses the Black-Scholes-Merton option-pricing model, which incorporates a number of valuation assumptions. The weighted-average fair value was estimated based on the following assumptions: risk-free interest rate of 1.46%; expected dividend yield of 0.55%; expected stock price volatility of 24.22%; and expected term of 5.5 years. In general, stock options vest after three years of continuous service and the values determined through this fair-value based method generally are amortized on a straight-line basis over the vesting term into Cost of sales, Selling, general and administrative expenses, or Research and development expenses, as appropriate.

During the nine months ended September 30, 2020, the company granted 234,064 RSUs, with a weighted-average grant date fair value of $143.68 per RSU. RSUs are accounted for using a fair-value-based method that utilizes the closing price of Zoetis common stock on the date of grant. In general, RSUs vest after three years of continuous service from the grant date and the values generally are amortized on a straight-line basis over the vesting term into Cost of sales, Selling, general and administrative expenses, or Research and development expenses, as appropriate.

During the nine months ended September 30, 2020, the company granted 85,279 PSUs with a weighted-average grant date fair value of $217.49 per PSU. PSUs are accounted for using a Monte Carlo simulation model. The units underlying the PSUs will be earned and vested over a three-year performance period, based upon the total shareholder return of the company in comparison to the total shareholder return of the companies comprising the S&P 500 stock market index at the start of the performance period, excluding companies that during the performance period are acquired or no longer publicly traded (Relative TSR). The weighted-average fair value was estimated based on volatility assumptions of Zoetis common stock and an average of the S&P 500 companies, which were 20.2% and 24.8%, respectively. Depending on the company’s Relative TSR performance at the end of the performance period, the recipient may earn from 0% to 200% of the target number of units. Vested units are settled in shares of the company’s common stock. PSU values are amortized on a straight-line basis over the vesting term into Cost of sales, Selling, general and administrative expenses, or Research and development expenses, as appropriate.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

15. Commitments and Contingencies

We and certain of our subsidiaries are subject to numerous contingencies arising in the ordinary course of business. For a discussion of our tax contingencies, see Note 8. Income Taxes.

A. Legal Proceedings

Our non-tax contingencies include, among others, the following:

•    Product liability and other product-related litigation, which can include injury, consumer, off-label promotion, antitrust and breach of contract claims.

•    Commercial and other matters, which can include product-pricing claims and environmental claims and proceedings.

•    Patent litigation, which typically involves challenges to the coverage and/or validity of our patents or those of third parties on various products or processes.

•    Government investigations, which can involve regulation by national, state and local government agencies in the U.S. and in other countries.

Certain of these contingencies could result in losses, including damages, fines and/or civil penalties, and/or criminal charges, which could be substantial.

We believe that we have strong defenses in these types of matters, but litigation is inherently unpredictable and excessive verdicts do occur. We do not believe that any of these matters will have a material adverse effect on our financial position. However, we could incur judgments, enter

into settlements or revise our expectations regarding the outcome of certain matters, and such developments could have a material adverse effect on our results of operations or cash flows in the period in which the amounts are paid.

We have accrued for losses that are both probable and reasonably estimable. Substantially all of these contingencies are subject to significant uncertainties and, therefore, determining the likelihood of a loss and/or the measurement of any loss can be complex. Consequently, we are unable to estimate the range of reasonably possible loss in excess of amounts accrued. Our assessments are based on estimates and assumptions that have been deemed reasonable by management, but the assessment process relies on estimates and assumptions that may prove to be incomplete or inaccurate, and unanticipated events and circumstances may occur that might cause us to change those estimates and assumptions.

Amounts recorded for legal and environmental contingencies can result from a complex series of judgments about future events and uncertainties and can rely on estimates and assumptions.

The principal matters to which we are a party are discussed below. In determining whether a pending matter is significant for financial reporting and disclosure purposes, we consider both quantitative and qualitative factors in order to assess materiality, such as, among other things, the amount of damages and the nature of any other relief sought in the proceeding, if such damages and other relief are specified; our view of the merits of the claims and of the strength of our defenses; whether the action purports to be a class action and our view of the likelihood that a class will be certified by the court; the jurisdiction in which the proceeding is pending; any experience that we or, to our knowledge, other companies have had in similar proceedings; whether disclosure of the action would be important to a reader of our financial statements, including whether disclosure might change a reader’s judgment about our financial statements in light of all of the information about the company that is available to the reader; the potential impact of the proceeding on our reputation; and the extent of public interest in the matter. In addition, with respect to patent matters, we consider, among other things, the financial significance of the product protected by the patent.

Ulianopolis, Brazil

In February 2012, the Municipality of Ulianopolis (State of Para, Brazil) filed a complaint against Fort Dodge Saúde Animal Ltda. (FDSAL), a Zoetis entity, and five other large companies alleging that waste sent to a local waste incineration facility for destruction, but that was not ultimately destroyed as the facility lost its operating permit, caused environmental impacts requiring cleanup.

The Municipality is seeking recovery of cleanup costs purportedly related to FDSAL's share of all waste accumulated at the incineration facility awaiting destruction, and compensatory damages to be allocated among the six defendants. We believe we have strong arguments against the claim, including defense strategies against any claim of joint and several liability.

At the request of the Municipal prosecutor, in April 2012, the lawsuit was suspended for one year. Since that time, the prosecutor has initiated investigations into the Municipality's actions in the matter as well as the efforts undertaken by the six defendants to remove and dispose of their individual waste from the incineration facility. On October 3, 2014, the Municipal prosecutor announced that the investigation remained ongoing and outlined the terms of a proposed Term of Reference (a document that establishes the minimum elements to be addressed in the preparation of an Environmental Impact Assessment), under which the companies would be liable to withdraw the waste and remediate the area.

On March 5, 2015, we presented our response to the prosecutor’s proposed Term of Reference, arguing that the proposed terms were overly general in nature and expressing our interest in discussing alternatives to address the matter. The prosecutor agreed to consider our request to engage a technical consultant to conduct an environmental diagnostic of the contaminated area. On May 29, 2015, we, in conjunction with the other defendant companies, submitted a draft cooperation agreement to the prosecutor, which outlined the proposed terms and conditions for the engagement of a technical consultant to conduct the environmental diagnostic. On August 19, 2016, the parties and the prosecutor agreed to engage the services of a third-party consultant to conduct a limited environmental assessment of the site. The site assessment was conducted during June 2017, and a written report summarizing the results of the assessment was provided to the parties and the prosecutor in November 2017. The report noted that waste is still present on the site and that further (Phase II) environmental assessments are needed before a plan to manage that remaining waste can be prepared. On April 1, 2019, the defendants met with the Prosecutor to discuss the conclusions set forth in the written report. Following that discussion, on April 10, 2019, the Prosecutor issued a procedural order requesting that the defendants prepare and submit a technical proposal outlining the steps needed to conduct the additional Phase II environmental assessments. The defendants presented the technical proposal to the Prosecutor on October 21, 2019. On March 3, 2020, the Prosecutor notified the defendants that he submitted the proposal to the Ministry of the Environment for its review and consideration. On July 15, 2020, the Prosecutor recommended certain amendments to the proposal for the Phase II testing. On September 28, 2020, the parties and the Prosecutor agreed to the final terms and conditions concerning the cooperation agreement with respect to the Phase II testing. We anticipate that the Phase II testing shall begin shortly.

Lascadoil Contamination in Animal Feed

An investigation by the U.S. Food and Drug Administration (FDA) and the Michigan Department of Agriculture into the alleged contamination of the feed supply of certain turkey and hog feed mills in Michigan led to the recall of certain batches of soy oil (intended for use as an animal feed additive) that had originated with Shur-Green Farms LLC, a producer of soy oil, and that had been contaminated with lascadoil, an industrial by-product of certain Zoetis manufacturing processes. The contaminated feed is believed to have caused the deaths of approximately 50,000 turkeys and the contamination (but not death) of at least 20,000 hogs in August 2014. The investigation posited that Shur-Green inadvertently contaminated soy oil with lascadoil which it purchased from Zoetis for use as a bio-fuel ingredient, and then sold the contaminated soy oil to fat recycling vendors, who in turn unknowingly sold to feed mills for use in animal feed.

During the course of its investigation, the FDA identified the process used to manufacture Zoetis’ Avatec® (lasalocid sodium) and Bovatec® (lasalocid sodium) products as the possible source of the lascadoil, since lascadoil contains small amounts of lasalocid, the active ingredient found in both products. Zoetis sold the industrial lascadoil byproduct to Shur-Green, through its broker, Heritage Interactive Services, LLC. Under the terms of the sale agreement, the lascadoil could only be incinerated or resold for use in biofuel and the agreement expressly prohibited the reselling of lascadoil for use as a component in food. The FDA inspected the Zoetis site where Avatec and Bovatec are manufactured, and found no evidence that Zoetis was involved in the contamination of the animal feed.

On March 10, 2015, plaintiffs Restaurant Recycling, LLC (Restaurant Recycling) and Superior Feed Ingredients, LLC (Superior), both of whom are in the fat recycling business, filed a complaint in the Seventeenth Circuit Court for the State of Michigan against Shur-Green Farms alleging negligence and breach of warranty claims arising from their purchase of soy oil allegedly contaminated with lascadoil. Plaintiffs resold the allegedly contaminated soy oil to turkey feed mills for use in feed ingredient. Plaintiffs also named Zoetis as a defendant in the complaint alleging that Zoetis failed to properly manufacture its products and breached an implied warranty that the soy oil was fit for use at turkey and hog mills. Zoetis was served with the complaint on June 3, 2015, and we filed our answer, denying all allegations, on July 15, 2015. On August 10, 2015, several of the turkey feed mills filed a joint complaint against Restaurant Recycling, Superior, Shur-Green Farms and others, alleging claims for negligence, misrepresentation, and breach of warranty, arising out of their alleged purchase and use of the contaminated soy oil. The complaint raises only one count against Zoetis for negligence. We filed an answer to the complaint on November 2, 2015, denying the allegation. On May 16, 2016, two additional turkey producers filed a complaint in the Seventeenth Circuit Court for the State of Michigan against the company, Restaurant Recycling, Superior, Shur-Green Farms and others, alleging claims for negligence and breach of warranties. We filed an answer to the complaint on June 20, 2016, denying the allegations. The Court has consolidated all three cases in Michigan for purposes of discovery and disposition. On July 28, 2017, we filed a motion for summary disposition on the grounds that no genuine issues of material fact exist and that Zoetis is entitled to judgment as a matter of law. On October 19, 2017, the Court granted our motion and dismissed all claims against Zoetis. On October 31, 2017, the plaintiffs filed motions for reconsideration of the Court's decision granting summary disposition. The Court, denied all such motions on December 6, 2017, for the same reasons cited in the Court’s original decision. On December 27, 2017, the plaintiffs filed a request with the Michigan Court of Appeals seeking an interlocutory (or interim) appeal of the lower Court’s decision, which we opposed on January 17, 2018. On July 5, 2018, the Court of Appeals denied the plaintiffs’ request for an interlocutory appeal. The case was remanded back to the lower Court, where it was scheduled to proceed to trial by jury. We have been advised that the remaining parties have reached an agreement to settle the dispute, and on June 24, 2020, the remaining parties jointly stipulated to the dismissal of all remaining claims. On July 13, 2020, Plaintiffs filed a claim of appeal with Michigan State Circuit Court seeking reversal of the lower Court’s decision granting Zoetis’ motion for summary disposition. Plaintiffs’ filed their appeal brief on October 29, 2020, and our reply brief is due on December 3, 2020. We intend to fully defend the appeal.

Other Matters

On February 14, 2019, the General Court of the European Union (General Court) annulled the January 11, 2016 decision of the European Commission (EC) that selective tax advantages granted by Belgium under its "excess profit" tax scheme constitute illegal state aid. On May 8, 2019, the EC filed an appeal to the decision of the General Court. On September 16, 2019, the EC opened separate in-depth investigations to assess whether Belgium excess profit rulings granted to 39 multinational companies, including Zoetis, constituted state aid for those companies. Due to the uncertainty with respect to the outcome of the appeal to be filed by the EC, the company has not reflected any potential benefits associated with the decision of the General Court in its consolidated financial statements as of September 30, 2020. We will continue to monitor the developments of the appeal and its ultimate resolution.

The EC published a decision on alleged competition law infringements by several human health pharmaceutical companies on June 19, 2013. One of the involved legal entities is Alpharma LLC (previously having the name Zoetis Products LLC). Alpharma LLC's involvement is solely related to its human health activities prior to Pfizer's acquisition of King/Alpharma. Zoetis paid a fine in the amount of 11 million euros (approximately $14 million) and was reimbursed in full by Pfizer in accordance with the Global Separation Agreement between Pfizer and Zoetis, which provides that Pfizer is obligated to indemnify Zoetis for any liabilities arising out of claims not related to its animal health assets. We filed an appeal of the decision on September 6, 2013, to the General Court of the European Union. On September 8, 2016, the General Court upheld the decision of the European Commission. On November 25, 2016, we filed an appeal to the Court of Justice of the European Union. On January 24, 2019, the Court heard oral argument on the merits of the appeal. On June 4, 2020, the Advocate General issued his non-binding opinion, which largely confirmed the decision of the General Court. We now await the Court’s decision.

B. Guarantees and Indemnifications

In the ordinary course of business and in connection with the sale of assets and businesses, we indemnify our counterparties against certain liabilities that may arise in connection with the transaction or related to activities prior to the transaction. These indemnifications typically pertain to environmental, tax, employee and/or product-related matters and patent-infringement claims. If the indemnified party were to make a successful claim pursuant to the terms of the indemnification, we would be required to reimburse the loss. These indemnifications are generally subject to threshold amounts, specified claim periods and other restrictions and limitations. Historically, we have not paid significant amounts under these provisions and, as of September 30, 2020, recorded amounts for the estimated fair value of these indemnifications were not significant.

Segment Reporting [Abstract]

Segment Information

16. Segment Information

Operating Segments

We manage our operations through two geographic operating segments: the U.S. and International. Each operating segment has responsibility for its commercial activities. Within each of these operating segments, we offer a diversified product portfolio, including vaccines, anti-infectives, parasiticides, dermatology, medicated feed additives, animal health diagnostics and other pharmaceuticals, for both livestock and companion animal customers. Our chief operating decision maker uses the revenue and earnings of the two operating segments, among other factors, for performance evaluation and resource allocation.

In the first quarter of 2020, the company realigned certain management responsibilities. These changes did not impact the determination of our operating segments, however they resulted in the reallocation of certain costs between segments. These changes primarily include the following: (i) R&D costs related to our aquaculture business, which were previously reported in our international commercial segment, are now reported in Other business activities; (ii) certain other miscellaneous costs, which were previously reported in international commercial segment results, are now reported in Corporate; and (iii) certain diagnostic and other miscellaneous costs, which were previously reported in our U.S. results, are now reported in Corporate.

Other Costs and Business Activities

Certain costs are not allocated to our operating segment results, such as costs associated with the following:

•    Other business activities, includes our Client Supply Services (CSS) contract manufacturing results, our human health business, and expenses associated with our dedicated veterinary medicine research and development organization, research alliances, U.S. regulatory affairs and other operations focused on the development of our products. Other R&D-related costs associated with non-U.S. market and regulatory activities are generally included in the international commercial segment.

•    Corporate, includes platform functions such as information technology, facilities, legal, finance, human resources, business development, certain diagnostic costs and communications, among others. These costs also include compensation costs and other miscellaneous operating expenses not charged to our operating segments, as well as interest income and expense.

•Certain transactions and events such as (i) Purchase accounting adjustments, where we incur expenses associated with the amortization of fair value adjustments to inventory, intangible assets and property, plant and equipment; (ii) Acquisition-related activities, where we incur costs associated with acquiring and integrating newly acquired businesses, such as transaction costs and integration costs; and (iii) Certain significant items, which comprise substantive, unusual items that, either as a result of their nature or size, would not be expected to occur as part of our normal business on a regular basis, such as restructuring charges and implementation costs associated with our cost-reduction/productivity initiatives that are not associated with an acquisition, certain asset impairment charges, certain legal and commercial settlements and the impact of divestiture-related gains and losses.

•Other unallocated includes (i) certain overhead expenses associated with our global manufacturing operations not charged to our operating segments; (ii) certain costs associated with information technology and finance that specifically support our global manufacturing operations; (iii) certain supply chain and global logistics costs; and (iv) procurement costs.

Segment Assets

We manage our assets on a total company basis, not by operating segment. Therefore, our chief operating decision maker does not regularly review any asset information by operating segment and, accordingly, we do not report asset information by operating segment.

Accounting Policies [Abstract]

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements were prepared following the requirements of the Securities and Exchange Commission (SEC) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by accounting principles generally accepted in the United States of America (U.S. GAAP) can be condensed or omitted. Balance sheet amounts and operating results for subsidiaries operating outside the U.S. are as of and for the nine-month periods ended August 31, 2020 and August 31, 2019.

Recently Adopted Accounting Standards and Recently Issued Accounting Standards

Recently Adopted Accounting Standards

In August 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Topic 350-40), an accounting standards update which expands the scope of costs associated with cloud computing arrangements that must be capitalized. Under the new guidance, costs associated with implementing a cloud computing arrangement that is a service contract must be capitalized and expensed over the term of the hosting arrangement. We adopted this guidance as of January 1, 2020, the required effective date, on a prospective basis. The adoption did not have a significant impact on our consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments (Topic 326), an accounting standards update which requires an entity to measure and recognize expected credit losses for certain financial instruments, including trade receivables, as an allowance that reflects the entity's current estimate of credit losses expected to be incurred. For available-for-sale debt securities with unrealized losses, the standard requires allowances to be recorded instead of reducing the amortized cost of the investment. We adopted this guidance as of January 1, 2020, the required effective date, on a prospective basis. The adoption did not have a significant impact on our consolidated financial statements.

Recently Issued Accounting Standards

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The new guidance provides temporary optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued because of reference rate reform. Adoption of the provisions of ASU 2020-04 is optional and effective as of March 12, 2020, but is only available through December 31, 2022. We are currently evaluating the impact that the new guidance will have on our consolidated financial statements and related disclosures, as well as the timing of the potential adoption

Tax Contingencies

Our tax liabilities for uncertain tax positions relate primarily to issues common among multinational corporations. Any settlements or statute of limitations expirations could result in a significant decrease in our uncertain tax positions. Substantially all of these unrecognized tax benefits, if recognized, would impact our effective income tax rate. We do not expect that within the next twelve months any of our uncertain tax positions could significantly decrease as a result of settlements with taxing authorities or the expiration of the statutes of limitations. Our assessments are based on estimates and assumptions that have been deemed reasonable by management, but our estimates of uncertain tax positions and potential tax benefits may not be representative of actual outcomes, and any variation from such estimates could materially affect our financial statements in the period of settlement or when the statutes of limitations expire, as we treat these events as discrete items in the period of resolution. Finalizing audits with the relevant taxing authorities can include formal administrative and legal proceedings, and, as a result, it is difficult to estimate the timing and range of possible changes related to our uncertain tax positions, and such changes could be significant.

Legal Proceedings

Our non-tax contingencies include, among others, the following:

•    Product liability and other product-related litigation, which can include injury, consumer, off-label promotion, antitrust and breach of contract claims.

•    Commercial and other matters, which can include product-pricing claims and environmental claims and proceedings.

•    Patent litigation, which typically involves challenges to the coverage and/or validity of our patents or those of third parties on various products or processes.

•    Government investigations, which can involve regulation by national, state and local government agencies in the U.S. and in other countries.

Certain of these contingencies could result in losses, including damages, fines and/or civil penalties, and/or criminal charges, which could be substantial.

We believe that we have strong defenses in these types of matters, but litigation is inherently unpredictable and excessive verdicts do occur. We do not believe that any of these matters will have a material adverse effect on our financial position. However, we could incur judgments, enter

into settlements or revise our expectations regarding the outcome of certain matters, and such developments could have a material adverse effect on our results of operations or cash flows in the period in which the amounts are paid.

We have accrued for losses that are both probable and reasonably estimable. Substantially all of these contingencies are subject to significant uncertainties and, therefore, determining the likelihood of a loss and/or the measurement of any loss can be complex. Consequently, we are unable to estimate the range of reasonably possible loss in excess of amounts accrued. Our assessments are based on estimates and assumptions that have been deemed reasonable by management, but the assessment process relies on estimates and assumptions that may prove to be incomplete or inaccurate, and unanticipated events and circumstances may occur that might cause us to change those estimates and assumptions.

Amounts recorded for legal and environmental contingencies can result from a complex series of judgments about future events and uncertainties and can rely on estimates and assumptions.

The principal matters to which we are a party are discussed below. In determining whether a pending matter is significant for financial reporting and disclosure purposes, we consider both quantitative and qualitative factors in order to assess materiality, such as, among other things, the amount of damages and the nature of any other relief sought in the proceeding, if such damages and other relief are specified; our view of the merits of the claims and of the strength of our defenses; whether the action purports to be a class action and our view of the likelihood that a class will be certified by the court; the jurisdiction in which the proceeding is pending; any experience that we or, to our knowledge, other companies have had in similar proceedings; whether disclosure of the action would be important to a reader of our financial statements, including whether disclosure might change a reader’s judgment about our financial statements in light of all of the information about the company that is available to the reader; the potential impact of the proceeding on our reputation; and the extent of public interest in the matter. In addition, with respect to patent matters, we consider, among other things, the financial significance of the product protected by the patent.

Guarantees and Indemnifications

B. Guarantees and IndemnificationsIn the ordinary course of business and in connection with the sale of assets and businesses, we indemnify our counterparties against certain liabilities that may arise in connection with the transaction or related to activities prior to the transaction. These indemnifications typically pertain to environmental, tax, employee and/or product-related matters and patent-infringement claims. If the indemnified party were to make a successful claim pursuant to the terms of the indemnification, we would be required to reimburse the loss. These indemnifications are generally subject to threshold amounts, specified claim periods and other restrictions and limitations. Historically, we have not paid significant amounts under these provisions and, as of September 30, 2020, recorded amounts for the estimated fair value of these indemnifications were not significant.

8. Income Taxes

A. Taxes on Income

Our effective tax rate was 19.8% for the three months ended September 30, 2020, compared with 18.0% for the three months ended September 30, 2019. The higher effective tax rate for the three months ended September 30, 2020, was primarily attributable to:

•a $14 million net discrete tax benefit recorded in the three months ended September 30, 2019, due to a change in tax basis related to purchase accounting,

partially offset by:

•a $4 million and $1 million discrete tax benefit recorded in the three months ended September 30, 2020 and 2019, respectively, related to the excess tax benefits for share-based payments.

Our effective tax rate was 18.9% for the nine months ended September 30, 2020, compared with 18.2% for the nine months ended September 30, 2019. The higher effective tax rate for the nine months ended September 30, 2020, was primarily attributable to:

•changes in the jurisdictional mix of earnings, which includes the impact of the location of earnings from operations and repatriation costs. The jurisdictional mix of earnings can vary as a result of repatriation decisions, operating fluctuations in the normal course of business and the impact of non-deductible items;

•a $19 million net discrete tax benefit recorded in the nine months ended September 30, 2019, primarily related to the effective settlement of certain issues with non-U.S. tax authorities and a prior period tax adjustment; and

•a $14 million net discrete deferred tax benefit recorded in the nine months ended September 30, 2019, due to a change in tax basis related to purchase accounting,

partially offset by:

•a $29 million and $17 million discrete tax benefit recorded in the nine months ended September 30, 2020 and 2019, respectively, related to the excess tax benefits for share-based payments;

•a $7 million discrete tax benefit recorded in the nine months ended September 30, 2020 related to a remeasurement of deferred taxes resulting from the integration of acquired businesses; and

•a $4 million and $3 million discrete tax benefit recorded in the nine months ended September 30, 2020 and 2019, respectively, related to a remeasurement of deferred taxes as a result of a change in non-U.S. statutory tax rates.

B. Deferred Taxes

As of September 30, 2020, the total net deferred income tax liability of $313 million is included in Noncurrent deferred tax assets ($97 million) and Noncurrent deferred tax liabilities ($410 million).

As of December 31, 2019, the total net deferred income tax liability of $346 million is included in Noncurrent deferred tax assets ($88 million) and Noncurrent deferred tax liabilities ($434 million).

C. Tax Contingencies

As of September 30, 2020, the net tax liabilities associated with uncertain tax positions of $192 million (exclusive of interest and penalties related to uncertain tax positions of $14 million) are included in Noncurrent deferred tax assets and Other noncurrent assets ($2 million) and Other taxes payable ($190 million).

As of December 31, 2019, the net tax liabilities associated with uncertain tax positions of $182 million (exclusive of interest and penalties related to uncertain tax positions of $12 million) are included in Noncurrent deferred tax assets and Other noncurrent assets ($2 million) and Other taxes payable ($180 million).

Our tax liabilities for uncertain tax positions relate primarily to issues common among multinational corporations. Any settlements or statute of limitations expirations could result in a significant decrease in our uncertain tax positions. Substantially all of these unrecognized tax benefits, if recognized, would impact our effective income tax rate. We do not expect that within the next twelve months any of our uncertain tax positions could significantly decrease as a result of settlements with taxing authorities or the expiration of the statutes of limitations. Our assessments are based on estimates and assumptions that have been deemed reasonable by management, but our estimates of uncertain tax positions and potential tax benefits may not be representative of actual outcomes, and any variation from such estimates could materially affect our financial statements in the period of settlement or when the statutes of limitations expire, as we treat these events as discrete items in the period of resolution. Finalizing audits with the relevant taxing authorities can include formal administrative and legal proceedings, and, as a result, it is difficult to estimate the timing and range of possible changes related to our uncertain tax positions, and such changes could be significant.
