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 and vaccines, 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, sheep and fish (collectively, livestock) and dogs, cats and horses (collectively, companion animals); and within five major product categories: anti-infectives, vaccines, parasiticides, medicated feed additives and other pharmaceuticals.


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 United States are as of and for the three-month periods ended February 28, 2018, and February 26, 2017.

Prior to fiscal 2018, the company followed a 13-week quarterly accounting cycle for each of the first three fiscal quarters. The company's fiscal year ends on December 31 for our operations in the United States and on November 30 for subsidiaries operating outside the United States. Beginning in fiscal 2018, the company's first three fiscal quarters will end on the last day of March, June and September in the United States and the last day of February, May and August for subsidiaries operating outside the United States. There is no change to the company's fiscal year-end dates. We did not adjust our results of operations for periods prior to 2018 as the impact was not material.

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.

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 2017 Annual Report on Form 10-K.


3.	Accounting Standards

Recently Adopted Accounting Standards

In March 2018, the Financial Accounting Standards Board (FASB) issued an accounting standards update to align existing guidance on accounting for income taxes, pursuant to guidance provided by a Staff Accounting Bulletin published by the SEC on December 22, 2017. The update addresses the challenges in accounting for the effects of the Tax Cuts and Jobs Act (the Tax Act), enacted on December 22, 2017, in the period of enactment and required companies to report provisional amounts for those specific income tax effects of the Tax Act for which the accounting is incomplete but a reasonable estimate can be determined. Provisional amounts will be subject to adjustment during a measurement period of up to one year from the enactment date. For additional information, see Note 7. Tax Matters.

In March 2017, the FASB issued an accounting standards update to simplify and improve the reporting of net periodic pension benefit cost by requiring only present service cost to be presented in the same line item as other current employee compensation costs while remaining components of net periodic benefit cost would be presented within Other (income)/deductions—net outside of operations. We adopted this guidance as of January 1, 2018, the required effective date. The new standard did not have a significant impact on our consolidated financial statements.

In October 2016, the FASB issued an accounting standards update that requires the recognition of the income tax consequences of an intra-entity asset transfer, other than inventory, when the transfer occurs as opposed to when the asset is sold to an outside third party. We adopted this guidance as of January 1, 2018, the required effective date. The new standard did not have a significant impact on our consolidated financial statements.

In May 2014, the FASB issued an accounting standards update that outlines a new, single comprehensive model for companies to use in accounting for revenue arising from contracts with customers. The core principle of the new guidance is that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We adopted this guidance as of January 1, 2018, the required effective date, using the modified retrospective adoption method. Prior period amounts have not been adjusted and continue to be reported in accordance with our historic

6 |

Table of Contents

accounting policies. Application of the standard using the modified retrospective method did not require an adjustment to opening retained earnings. For additional information, see Note 4. Revenue.

Recently Issued Accounting Standards

In February 2018, the FASB issued an accounting standards update which permits companies to reclassify from accumulated other comprehensive income to retained earnings stranded tax effects resulting from the new federal corporate income tax rate. In the period of adoption, a company may choose to either apply the amendments retrospectively to each period in which the effect of the change in federal income tax rate is recognized or to apply the amendments in that reporting period. The provisions of the update are effective beginning January 1, 2019 for interim and annual periods, with early adoption permitted for any interim period after issuance of the update. We are currently assessing the timing of our adoption and do not expect that the new standard will have a significant impact on our consolidated financial statements.

In August 2017, the FASB issued an accounting standards update which amends the hedge accounting recognition and presentation requirements and allows for more hedging strategies to be eligible for hedge accounting. Recognition of periodic hedge effectiveness will no longer be required for cash flow and net investment hedges and companies may elect to perform subsequent hedge effectiveness assessments qualitatively. The update also clarifies that the change in fair value of a derivative must be recorded in the same income statement line item as the earnings effect of the hedged item and introduces additional disclosure requirements including cumulative basis adjustments for fair value hedges and the effect of hedging on individual income statement line items. The provisions of the update are effective beginning January 1, 2019 for interim and annual periods with early adoption permitted for any interim period after issuance of the update. We are currently assessing the timing of our adoption as well as the potential impact that the standard will have on our consolidated financial statements.

In February 2016, the FASB issued an accounting standards update which requires lessees to recognize most leases on the balance sheet with a corresponding right of use asset. Leases will be classified as financing or operating which will drive the expense recognition pattern. For lessees, the income statement presentation and expense recognition pattern for financing and operating leases is similar to the current model for capital and operating leases, respectively. Companies may elect to exclude short-term leases. The update also requires additional disclosures that will better enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. We plan to adopt this guidance as of January 1, 2019, the required effective date, for annual and interim reporting periods. The new standard requires a modified retrospective adoption approach, at the beginning of the earliest comparative period presented in the financial statements. We have selected a lease accounting system and are currently evaluating our lease contracts, accounting policy elections, and the impact of adoption on our consolidated financial statements. While we do not expect adoption of the standard to have a significant impact on our consolidated statements of income, the impact on the assets and liabilities within our consolidated balance sheet may be material.


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. 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 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 and vaccines, complemented by biodevices, diagnostics, and genetics. 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.

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;


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


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


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

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 and vaccines 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 Accounting Policy

Below are the significant accounting policies updated as of January 1, 2018 as a result of the adoption of the new revenue recognition guidance. For additional information, see Note 3. Accounting Standards.

We recognize revenue from product sales when control of the goods has transferred to the customer, which is typically once the goods have shipped and the customer has assumed title. Revenue reflects the total consideration to which we expect to be entitled (i.e. the transaction price), in exchange for products sold, after considering various types of variable consideration including rebates, sales allowances, product returns and discounts.

Variable consideration is estimated and recorded at the time that related revenue is recognized. Our estimates reflect the amount by which we expect variable consideration to impact revenue recognized and are generally based on contractual terms or historical experience, adjusted as necessary to reflect our expectations about the future. Our customer payment terms generally range from 60 to 90 days.

Estimates of variable consideration utilize a complex series of judgments and assumptions to determine the amount by which we expect revenue to be reduced, for example;

•

for sales returns, we perform calculations in each market that incorporate the following, as appropriate: local returns policies and practices; historic returns as a percentage of revenue; estimated shelf life by product; an estimate of the amount of time between shipment and return or lag time; and any other factors that could impact the estimate of future returns, product recalls, discontinuation of products or a changing competitive environment; and


•	for revenue incentives, we use our historical experience with similar incentives programs to estimate the impact of such programs on revenue for the current period.

Although the amounts recorded for these revenue deductions are dependent on estimates and assumptions, historically our adjustments to actual results have not been material. The sensitivity of our estimates can vary by program, type of customer and geographic location.

A deferral of revenue may be required in the event that we have not satisfied all customer obligations for which we have been compensated. The transaction price is allocated to the individual performance obligations on the basis of relative stand-alone selling price, which is typically based on actual sales prices. Revenue associated with unsatisfied performance obligations are contract liabilities, is recorded within Other current liabilities, and is recognized once control of the underlying products has transferred to the customer. Contract liabilities reflected within Other current liabilities as of the adoption date and subsequently recognized as revenue during the first quarter of 2018 were approximately $2 million. Contract liabilities as of March 31, 2018 were approximately $4 million.

We do not disclose the transaction price allocated to unsatisfied performance obligations related to contracts with an original expected duration of one year or less, or for contracts for which we recognize revenue in line with our right to invoice the customer. Estimated future revenue expected to be generated from long-term contracts with unsatisfied performance obligations as of March 31, 2018 are not material.

Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from Revenue. Shipping and handling costs incurred after control of the purchased product has transferred to the customer are accounted for as a fulfillment cost, within Selling, general and administrative expenses.


5.	Restructuring Charges and Other Costs Associated with Acquisitions and Cost-Reduction/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 research and development (R&D), as well as functions such as business technology, shared services and corporate operations.

During 2015, we launched a comprehensive operational efficiency program, which was incremental to the previously announced supply network strategy. These initiatives focused on reducing complexity in our product portfolios, changing our selling approach in certain markets, reducing our presence in certain countries, and exiting manufacturing sites over a long term period. We have also continued to optimize our resource allocation and efficiency by reducing resources associated with non-customer facing activities and operating more efficiently as a result of less internal complexity and more standardization of processes. As part of these initiatives, we planned to reduce certain positions through divestitures, normal attrition and involuntary terminations by approximately 2,800, subject to consultations with works councils and unions in certain countries. Including divestitures, as of March 31, 2018, approximately 2,600 positions have been eliminated related to these initiatives. The comprehensive operational efficiency program was substantially completed as of December 31, 2017. We expect to complete the supply network strategy over the next several years.

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

7.	Income Taxes


A.	Taxes on Income

On December 22, 2017, the Tax Act was enacted which, among other changes, reduced the U.S. federal corporate tax rate from 35% to 21% effective January 1, 2018. The Tax Act made broad and complex changes to the U.S. tax code and it will take time to fully analyze the impact of the changes. Based on the information available at that time, and the current interpretation of the Tax Act, for the year ended December 31, 2017 the company was able to make a reasonable estimate and recorded an initial provisional net tax expense of $212 million related to the one-time mandatory deemed repatriation tax, payable over eight years, partially offset by the remeasurement of the deferred tax assets and liabilities, as of the date of enactment, due to the reduction in the U.S. federal corporate tax rate. Pursuant to the Staff Accounting Bulletin published by the SEC on December 22, 2017, addressing the challenges in accounting for the effects of the Tax Act in the period of enactment, companies must report provisional amounts for those specific income tax effects of the Tax Act for which the accounting is incomplete but a reasonable estimate can be determined. Those provisional amounts will be subject to adjustment during a measurement period of up to one year from the enactment date (measurement-period adjustment). Pursuant to this guidance, the estimated impact of the Tax Act was based on a preliminary review of the new tax law and projected future financial results and is subject to revision based upon further analysis and interpretation of the Tax Act and to the extent that future results differ from currently available projections.

Our accounting for the following elements of the Tax Act is incomplete. However, we were able to further refine our initial reasonable estimate and adjusted the initial provisional net tax expense of $212 million and recorded the following measurement-period adjustments during the first quarter of 2018:

•

One-Time Mandatory Deemed Repatriation Tax: The one-time mandatory deemed repatriation tax is a tax on certain previously untaxed accumulated and current earnings and profits (E&P) of our foreign subsidiaries. We were able to reasonably estimate the one-time mandatory deemed repatriation tax and recorded an initial provisional tax obligation, with a corresponding adjustment to income tax expense for the year ended December 31, 2017. We are continuing to gather additional information to more precisely compute the amount of the one-time mandatory deemed repatriation tax, and our accounting for this item is not yet complete due to the fact that the non-U.S. subsidiaries are on a fiscal year ending November 30, and this tax liability will not become a fixed obligation until November 30, 2018. The estimated impact of the Tax Act is based on a preliminary review of the new law and projected future financial results and is subject to revision based upon further analysis and interpretation of the Tax Act and to the extent that future results differ from currently available projections. However, on the basis of revised E&P computations that were calculated during the reporting period, we recognized a measurement-period adjustment of $2 million as a decrease to the one-time mandatory deemed repatriation tax obligation, with a corresponding adjustment to income tax benefit during the period. The effect of the measurement-period adjustment to the first quarter 2018 effective tax rate was a reduction to the rate of approximately 0.6%. In addition, we reclassified the one-time mandatory deemed repatriation tax from Noncurrent deferred tax liabilities to Income taxes payable and Other taxes payable. We expect to complete our accounting within the prescribed measurement period.

•

Reduction of U.S. Federal Corporate Tax Rate: The Tax Act reduced the corporate tax rate to 21%, effective January 1, 2018. Consequently, we recorded a decrease related to deferred tax assets and liabilities with a corresponding net adjustment to deferred income tax benefit for the year ended December 31, 2017. We have not made any measurement-period adjustments related to this item during the first quarter of 2018. Since the company has recorded provisional amounts related to certain portions of the Tax Act, any corresponding deferred tax remeasurement is also provisional. However, we are continuing to gather additional information to complete our accounting for this item and expect to be completed within the prescribed measurement period.

•

Valuation Allowances: The company must assess whether its valuation allowance analyses are affected by the various aspects of the Tax Act (e.g., one-time mandatory deemed repatriation of deferred foreign income, global intangible low-taxed income inclusions, and new categories of foreign tax credits). We have not made any measurement-period adjustments related to this item during the first quarter of 2018. Since the company has recorded provisional amounts related to certain portions of the Tax Act, any corresponding determination of the need for or change in a valuation allowance is also provisional. However, we are continuing to gather additional information to complete our accounting for this item and expect to be completed within the prescribed measurement period.

•

Global Intangible Low-Taxed Income (GILTI) Policy Election: The GILTI provisions of the Tax Act do not apply to the company until 2019, due to the fact that the non-U.S. subsidiaries are on a fiscal year ending November 30, and we are still evaluating its impact. The FASB allows companies to adopt an accounting policy to either recognize deferred taxes for GILTI or treat such tax cost as a current-period expense when incurred. We have not yet determined our accounting policy because determining the impact of the GILTI provisions requires analysis of our existing legal entity structure, the reversal of our U.S. GAAP and U.S. tax basis differences in the assets and liabilities of our foreign subsidiaries, and our ability to offset any tax with foreign tax credits. As such, we have not made a policy decision whether to record deferred taxes on GILTI or treat such tax cost as a current-period expense.

The effective tax rate was 16.1% for the three months ended March 31, 2018, compared with 29.1% for the three months ended April 2, 2017. The lower effective tax rate for the three months ended March 31, 2018, was primarily attributable to:


•	the reduction of the U.S. federal corporate income tax rate from 35% to 21%, effective January 1, 2018, pursuant to the Tax Act;


•	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 and operating fluctuations in the normal course of business and the impact of non-deductible items;


•	an $8 million and $5 million discrete tax benefit recorded in the first quarter of 2018 and 2017, respectively, related to the excess tax benefits for share-based payments;

Table of Contents


•	an $8 million and $3 million discrete tax benefit recorded in the first quarter of 2018 and 2017, respectively, related to a remeasurement of deferred taxes as a result of a change in non-U.S. statutory tax rates; and


•	a $2 million net discrete tax benefit recorded in the first quarter of 2018, associated with a measurement-period adjustment related to the provisional one-time mandatory deemed repatriation tax on the company's undistributed non-U.S. earnings pursuant to the Tax Act enacted on December 22, 2017.


B.	Deferred Taxes

As of March 31, 2018, the total net deferred income tax liability of $166 million is included in Noncurrent deferred tax assets ($80 million) and Noncurrent deferred tax liabilities ($246 million).

As of December 31, 2017, the total net deferred income tax liability of $300 million is included in Noncurrent deferred tax assets ($80 million) and Noncurrent deferred tax liabilities ($380 million).

The change in Noncurrent deferred tax liabilities was primarily due to the reclassification of the one-time mandatory deemed repatriation tax from Noncurrent deferred tax liabilities to Income taxes payable and Other taxes payable to properly reflect the liability, which became a fixed obligation in 2018 payable over eight years.


C.	Tax Contingencies

As of March 31, 2018, the tax liabilities associated with uncertain tax positions of $191 million (exclusive of interest and penalties related to uncertain tax positions of $12 million) are included in Noncurrent deferred tax assets ($4 million) and Other taxes payable ($187 million).

As of December 31, 2017, the tax liabilities associated with uncertain tax positions of $164 million (exclusive of interest and penalties related to uncertain tax positions of $11 million) are included in Noncurrent deferred tax assets ($3 million) and Other taxes payable ($161 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.


8.	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 five-year $1.0 billion senior unsecured revolving credit facility (the credit facility). In December 2017, the maturity for the amended and restated revolving credit agreement was extended through December 2022. 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 clause which adds back to Adjusted Consolidated EBITDA, any operational efficiency restructuring charge (defined as charges recorded by the company during the period commencing on October 1, 2016 and ending December 31, 2019, related to operational efficiency initiatives), provided that for any twelve-month period such charges added back to Adjusted Consolidated EBITDA shall not to exceed $100 million in the aggregate.

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 March 31, 2018, and December 31, 2017. There were no amounts drawn under the credit facility as of March 31, 2018, or December 31, 2017.

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 March 31, 2018, we had access to $71 million of lines of credit which expire at various times throughout 2018 and 2019 and are generally renewed annually. We did not have any borrowings outstanding related to these facilities as of March 31, 2018, and December 31, 2017.

Commercial Paper Program and Other Short-Term Borrowings

In February 2013, we entered into a commercial paper program with a capacity of up to $1.0 billion. As of March 31, 2018, and December 31, 2017, there was no commercial paper outstanding under this program. As of March 31, 2018, and December 31, 2017, we did not have any other short-term borrowings outstanding.

Senior Notes and Other Long-Term Debt

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. These notes are comprised of $750 million aggregate principal amount of 3.000% senior notes due 2027 and $500 million aggregate principal amount of 3.950% senior notes due 2047. Net proceeds from this offering were partially used in October 2017 to repay, prior to maturity, the aggregate principal amount of $750 million, and a make-whole amount and accrued interest of $4 million, of our 1.875% senior notes due 2018. The remainder of the net proceeds will be used for general corporate purposes.

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 (the 2013 senior notes offering) in a private placement, with an original issue discount of $10 million.

The 2013, 2015 and 2017 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 and 2017 senior notes may be declared immediately due and payable.

Pursuant to the indenture, we are able to redeem the 2013, 2015 and 2017 senior notes, 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. 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 and 2017 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 and 2017 senior notes at a price equal to 101% of the aggregate principal amount of the 2013, 2015 and 2017 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:



	March 31,			December 31,
(MILLIONS OF DOLLARS)	2018			2017
3.450% 2015 senior notes due 2020	$	500		$	500

Unamortized debt discount / debt issuance costs	(46		)	(47		)
Long-term debt, net of discount and issuance costs	$	4,954		$	4,953

The fair value of our long-term debt was $5,083 million and $5,291 million as of March 31, 2018, and December 31, 2017, 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 March 31, 2018, matures in the following years:

Maturities	$	—	$	500	$	—	$	—	$	4,500	$	5,000

Interest Expense

Interest expense, net of capitalized interest, was $47 million and $41 million for the three months ended March 31, 2018, and April 2, 2017, respectively. Capitalized interest expense was $2 million and $1 million for the three months ended March 31, 2018, and April 2, 2017, 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 derivative financial instruments. These financial instruments serve to protect net income against the impact of the translation into U.S. dollars of certain foreign exchange-denominated transactions. The aggregate notional amount of foreign exchange derivative financial instruments offsetting foreign currency exposures was $1.5 billion and $1.4 billion, as of March 31, 2018, and

14 |

Table of Contents

December 31, 2017, respectively. The derivative financial instruments primarily offset exposures in the Australian dollar, Brazilian real, British pound, Canadian dollar, Chinese renminbi, euro, and Norwegian krone. The vast majority of the foreign exchange derivative financial instruments mature within 60 days and all mature within 270 days.

All derivative contracts 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 company has not designated the foreign currency forward-exchange contracts 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.

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. 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. To the extent these hedges of cash flows related to anticipated debt are effective, any unrealized gains or losses on the forward-starting interest rate swaps are reported in Accumulated other comprehensive loss and are recognized in income 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.

During 2017 and 2016, we entered into forward starting interest rate swaps with an aggregate notional value of $500 million. During the third quarter of 2017, we also entered in treasury lock trades with an aggregate notional value of $500 million. We designated these swaps and treasury locks (contracts) as cash flow hedges against interest rate exposure related principally to the anticipated future issuance of fixed-rate debt to be used primarily to refinance our 1.875% 2013 senior note due in 2018.

Upon issuance of our 2017 senior notes (see A. Debt: Senior Notes and Other Long-Term Debt), we terminated these contracts and paid $3 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 2017 senior notes. There was $0.1 million of ineffectiveness related to the forward swaps through the date of settlement which was immediately recognized as a loss within Interest expense—net of capitalized interest. In addition, in previous years we had entered into various forward-starting interest rate swap contracts that were designated as cash flow hedges and that were terminated upon issuance of fixed-rate notes. There were no outstanding interest rate swap contracts as of both March 31, 2018, and December 31, 2017.

Fair Value of Derivative Instruments

The classification and fair values of derivative instruments are as follows:



		Fair Value of Derivatives
		March 31,			December 31,
(MILLIONS OF DOLLARS)	Balance Sheet Location	2018			2017
Derivatives Not Designated as Hedging Instruments
Foreign currency forward-exchange contracts	Other current assets	$	11		$	10
Foreign currency forward-exchange contracts	Other current liabilities	(11		)	(9		)
Total derivatives not designated as hedging instruments		$	—		$	1

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



	Three Months Ended
	March 31,		April 2,
(MILLIONS OF DOLLARS)	2018		2017
Foreign currency forward-exchange contracts	$	10	$	29

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 derivative instruments designated as cash flow hedges, recorded, net of tax, in Other comprehensive income/(loss) were insignificant for both of the three months ended March 31, 2018 and April 2, 2017.

The net amount of deferred gains/(losses) related to derivative instruments designated as cash flow hedges that is expected to be reclassified from Accumulated other comprehensive loss into earnings over the next 12 months is insignificant.

C.	Amortization

Amortization expense related to finite-lived acquired intangible assets that contribute to our ability to sell, manufacture, research, market and distribute products, compounds and intellectual property is included in Amortization of intangible assets as it benefits multiple business functions. Amortization expense related to finite-lived acquired intangible assets that are associated with a single function is included in Cost of sales, Selling, general and administrative expenses or Research and development expenses, as appropriate. Total amortization expense for finite-lived intangible assets was $25 million for each of the three months ended March 31, 2018, and April 2, 2017.

11.	Benefit Plans

Our employees ceased to participate in the Pfizer, Inc. U.S. qualified defined benefit plans and the U.S. retiree medical plan effective December 31, 2012, and liabilities associated with our employees under these plans were retained by Pfizer. Pfizer continued to credit certain employees' service with Zoetis through December 31, 2017 (or termination of employment from Zoetis, if earlier) for certain early retirement benefits with respect to Pfizer's U.S. defined benefit pension and retiree medical plans. Pension and postretirement benefit expense associated with the extended service for certain employees in the U.S. plans totaled approximately $2 million in each three month period ended March 31, 2018, and April 2, 2017.

The following table provides the net periodic benefit cost associated with our international defined benefit pension plans:



	Three Months Ended
	March 31,			April 2,
(MILLIONS OF DOLLARS)	2018			2017
Service cost	$	2		$	2
Interest cost	1			1
Expected return on plan assets	(1		)	(1		)
Curtailment and settlement loss	—			1
Net periodic benefit cost	$	2		$	3

Total company contributions to the international pension plans were $2 million and $3 million for the three months ended March 31, 2018, and April 2, 2017, respectively. We expect to contribute a total of approximately $6 million to these plans in 2018.


12.	Share-Based Payments

The company may grant a variety of share-based payments under the Zoetis 2013 Equity and Incentive Plan (the Equity Plan) 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
	March 31,		April 2,
(MILLIONS OF DOLLARS)	2018		2017
Stock options / stock appreciation rights	$	2	$	3
RSUs / DSUs	7		6
PSUs	2		2
Share-based compensation expense—total^(a)	$	11	$	11


^(a)	For the three months ended March 31, 2018, and April 2, 2017, amounts capitalized to inventory were insignificant.

During the three months ended March 31, 2018, the company granted 536,070 stock options with a weighted-average exercise price of $73.26 per stock option and a weighted-average fair value of $20.29 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 2.74%; expected dividend yield of 0.69%; expected stock price volatility of 23.62%; and expected term of 6.5 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 three months ended March 31, 2018, the company granted 428,976 RSUs with a weighted-average grant date fair value of $73.25 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 three months ended March 31, 2018, the company granted 109,574 PSUs with a weighted-average grant date fair value of $100.34 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 index at the start of the performance period (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 21.9% and 25.1%, respectively. Depending on the company’s Relative TSR performance at the end of the performance period, the recipient may earn between 0% and 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 2016, the company's Board of Directors authorized a $1.5 billion share repurchase program. Purchases of Zoetis shares may be made at the discretion of management, depending on market conditions and business needs. As of March 31, 2018, there was approximately $810 million remaining under this authorization.

Changes in common shares and treasury stock were as follows:



(MILLIONS)	Common Shares Issued^(a)	Treasury Stock^(a)

Includes the issuance of shares of common stock and the reissuance of shares from treasury stock in connection with the vesting of employee share-based awards. Treasury stock also includes the reacquisition of shares associated with the vesting of employee share-based awards to satisfy tax withholding requirements. For additional information regarding share-based compensation, see Note 12. Share-Based Payments.

14.	Earnings per Share

The following table presents the calculation of basic and diluted earnings per share:



	Three Months Ended
	March 31,			April 2,
(MILLIONS OF DOLLARS AND SHARES, EXCEPT PER SHARE DATA)	2018			2017
Numerator
Net income before allocation to noncontrolling interests	$	350		$	239
Less: Net (loss)/income attributable to noncontrolling interests	(2		)	1
Net income attributable to Zoetis Inc.	$	352		$	238
Denominator
Weighted-average common shares outstanding	485.9			492.4
Common stock equivalents: stock options, RSUs, PSUs and DSUs	3.9			2.9
Weighted-average common and potential dilutive shares outstanding	489.8			495.3

Earnings per share attributable to Zoetis Inc. stockholders—basic	$	0.72		$	0.48
Earnings per share attributable to Zoetis Inc. stockholders—diluted	$	0.72		$	0.48

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 months ended March 31, 2018, and approximately 1 million for the three months ended April 2, 2017.

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 7. 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 United States 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 environmental assessments are needed before a plan to manage that remaining waste can be prepared. We have not received any further communication from the prosecutor in response to the report.

Lascadoil Contamination in Animal Feed

An investigation by the U.S. Food and Drug Administration (FDA) and the Michigan Department of Agriculture is ongoing to determine how lascadoil, oil for industrial use, made its way into the feed supply of certain turkey and hog feed mills in Michigan. 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. While it remains an open question as to how the lascadoil made its way into the animal feed, the allegations are that lascadoil intended to be sold for reuse as biofuel was inadvertently sold to producers of soy oil, who in turn, unknowingly sold the contaminated soy oil to fat recycling vendors, who then sold the contaminated soy oil to feed mills for use in animal feed. Indeed, related to the FDA investigation, Shur-Green Farms LLC, a producer of soy oil, recalled certain batches of soy oil allegedly contaminated with lascadoil on October 13, 2014.

During the course of its investigation, the FDA identified the process used to manufacture Zoetis’ Avatec® (lasalocid sodium) and Bovatec® (lasalocid sodium) products as one possible source of the lascadoil, since lascadoil contains small amounts of lasalocid, the active ingredient found in both products. Zoetis has historically sold any and all industrial lascadoil byproduct to an environmental company specializing in waste disposal. The environmental company is contractually obligated to incinerate the lascadoil or resell it for use in biofuel. Under the terms of the agreement, the environmental company is expressly prohibited from reselling the lascadoil to be used 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 appeal of the lower Court’s decision, which we opposed on January 17, 2018. The matter is stayed pending a decision by the Court of Appeals.

Other Matters

The European Commission 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 Euro 11 million (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 and are awaiting a ruling.


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 March 31, 2018, 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 United States 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, parasiticides, anti-infectives, medicated feed additives 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 2018, 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 Other business activities are now reported in the international commercial segment results, and ii) certain other miscellaneous costs which were previously reported in Corporate are now reported in the international commercial segment results.

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, as well as 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 our aquaculture business and non-U.S. market and regulatory activities are generally included in the international commercial segment.


•	Corporate, which is responsible for platform functions such as business technology, facilities, legal, finance, human resources, business development, and communications, among others. These costs also include compensation costs, certain procurement 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 certain costs related to becoming an independent public company, 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 business technology and finance that specifically support our global manufacturing operations; (iii) certain supply chain and global logistics costs; and (iv) certain 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 March 31, 2018, the related condensed consolidated statements of income, comprehensive income, equity and cash flows for the three-month periods ended March 31, 2018 and April 2, 2017, 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, 2017, 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 15, 2018, 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, 2017, 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 and vaccines, with a focus on both livestock and companion animals. For more than 60 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 businesses 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 the industry’s largest sales organization, 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. Additionally, our management team’s focus on improving operational and cost efficiencies increases the likelihood of achieving our core growth strategies and enhancing long-term value for our shareholders.

A summary of our 2018 performance compared with the comparable 2017 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 2017 Annual Report on Form 10-K. Set forth below are updates to certain of the factors disclosed in our 2017 Form 10-K.

Quarterly Variability of Financial Results

Our quarterly financial results are subject to variability related to a number of factors including but not limited to: 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 three months ended March 31, 2018, approximately 51% 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 Australian dollar, Brazilian real, Canadian dollar, Chinese yuan, euro, 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 three months ended March 31, 2018, approximately 49% of our total revenue was in U.S. dollars. Our year-over-year revenue growth was favorably impacted by approximately 4% 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 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 attributable to Zoetis and reported EPS. See the Adjusted Net Income section below for more information.

During 2015, we launched a comprehensive operational efficiency program, which was incremental to the previously announced supply network strategy. These initiatives focused on reducing complexity in our product portfolios, changing our selling approach in certain markets, reducing our presence in certain countries, and exiting manufacturing sites over a long term period. We have also continued to optimize our resource allocation and efficiency by reducing resources associated with non-customer facing activities and operating more efficiently as a result of less internal complexity and more standardization of processes. As part of these initiatives, we planned to reduce certain positions through divestitures, normal attrition and involuntary terminations by approximately 2,800, subject to consultations with works councils and unions in certain countries. Including divestitures, as of March 31, 2018, approximately 2,600 positions have been eliminated as part of these initiatives. The comprehensive operational efficiency program was substantially completed as of December 31, 2017. We expect to complete the supply network strategy over the next several years.

Our acquisition-related costs primarily relate to restructuring charges for employees, assets and activities that will not continue in the future, as well as integration costs. The majority of these net restructuring charges are related to termination costs, but we also exited a number of distributor and other contracts and performed certain facility rationalization efforts. Our integration costs are generally comprised of consulting costs related to the integration of systems and processes, as well as product transfer costs.

For additional information regarding restructuring charges and acquisition-related costs, see Notes to Condensed Consolidated Financial Statements— Note 5. Restructuring Charges and Other Costs Associated with Acquisitions and Cost-Reduction/Productivity Initiatives.

Three months ended March 31, 2018 vs. three months ended April 2, 2017

The change in restructuring charges and certain acquisition-related costs from a $1 million reversal in the three months ended April 2, 2017, to $2 million in the three months ended March 31, 2018, is primarily the result of higher employee termination costs as a result of our supply network strategy, in addition to integration costs.

On December 22, 2017, the Tax Cuts and Jobs Act (the Tax Act) was enacted which, among other changes, reduced the U.S. federal corporate tax rate from 35% to 21% effective January 1, 2018. The Tax Act made broad and complex changes to the U.S. tax code and it will take time to fully analyze the impact of the changes. Based on the information available at that time, and the current interpretation of the Tax Act, for the year ended December 31, 2017 the company was able to make a reasonable estimate and recorded an initial provisional net tax expense of $212 million related to the one-time mandatory deemed repatriation tax, payable over eight years, partially offset by the remeasurement of the deferred tax assets and liabilities, as of the date of enactment, due to the reduction in the U.S. federal corporate tax rate. Pursuant to the Staff Accounting Bulletin published by the Securities and Exchange Commission on December 22, 2017, addressing the challenges in accounting for the effects of the Tax Act in the period of enactment, companies must report provisional amounts for those specific income tax effects of the Tax Act for which the accounting is incomplete but a reasonable estimate can be determined. Those provisional amounts will be subject to adjustment during a measurement period of up to one year from the enactment date (measurement-period adjustment). Pursuant to this guidance, the estimated impact of the Tax Act was based on a preliminary review of the new tax law and projected future financial results and is subject to revision based upon further analysis and interpretation of the Tax Act and to the extent that future results differ from currently available projections.

Three months ended March 31, 2018 vs. three months ended April 2, 2017


•	reduction of the U.S. federal corporate income tax rate, effective January 1, 2018, pursuant to the Tax Act;


•	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 and operating fluctuations in the normal course of business and the impact of non-deductible items;


•	a $8 million and $5 million discrete tax benefit recorded in the first quarter of 2018 and 2017, respectively, related to the excess tax benefits for share-based payments;


•	a $8 million and $3 million discrete tax benefit recorded in the first quarter of 2018 and 2017, respectively, related to a remeasurement of deferred taxes as a result of a change in non-U.S. statutory tax rates; and


•	a $2 million net discrete tax benefit recorded in the first quarter of 2018, associated with a measurement-period adjustment related to the provisional one-time mandatory deemed repatriation tax on the company's undistributed non-U.S. earnings pursuant to the Tax Act enacted on December 22, 2017.

Three months ended March 31, 2018 vs. three months ended April 2, 2017

U.S. operating segment

U.S. segment revenue increased by $29 million, or 5%, in the three months ended March 31, 2018, compared with the three months ended April 2, 2017, reflecting growth of approximately $19 million in companion animal products and growth of approximately $10 million in livestock products.


•	Companion animal revenue growth was driven primarily by increased sales in our dermatology portfolio, as well as new products. Growth was tempered by lower sales of certain in-line products due to expected competition.

•

Livestock revenue increased primarily due to higher sales of cattle and poultry products and a return to growth in our swine business. Growth of cattle products was driven by favorable market conditions in the beef market, including higher feedlot placements and variable weather conditions, which drove higher disease risk and incidence. Growth was partially offset by unfavorable market conditions in dairy, including declining producer profitability due to low milk prices. For poultry, growth was driven by increased sales of medicated feed additive products.

U.S. segment earnings increased by $26 million, or 7%, in the three months ended March 31, 2018, compared with the three months ended April 2, 2017, primarily due to revenue growth and improved gross margins.

31 |

International operating segment

International segment revenue increased by $111 million, or 18%, in the three months ended March 31, 2018, compared with the three months ended April 2, 2017. Operational revenue increased by $65 million, or 11%, driven by growth of approximately $37 million in companion animal products and growth of approximately $28 million in livestock products.


•	Companion animal revenue growth resulted primarily from increased sales across multiple international markets of our dermatology portfolio, and new products including Simparica^®, as well as growth invaccines in China.


•	Livestock growth was driven primarily by strong performance in poultry and cattle products. Growth in poultry products was driven by increased sales of medicated feed additives, primarily in emerging markets. Cattle products grew due to the colder weather increasing treatments and strong demand for vaccines in Mexico. Strong demand in other emerging markets also contributed to growth.

Additionally, segment revenue was favorably impacted by foreign exchange, which increased revenue by approximately $46 million, or 7%, primarily driven by the appreciation of the euro, U.K. pound, Chinese renminbi, Mexican peso and Australian dollar.

International segment earnings increased by $67 million, or 23%, in the three months ended March 31, 2018, compared with the three months ended April 2, 2017. Operational earnings growth was $43 million, or 15%, primarily due to higher revenue and improved gross margin, partially offset by higher operating expenses.

Other business activities

Other business activities includes our Client Supply Services (CSS) contract manufacturing results, as well as 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 respective regional segment.

Three months ended March 31, 2018 vs. three months ended April 2, 2017

Other business activities net loss increased by $7 million, or 9%, in the three months ended March 31, 2018, compared with the three months ended April 2, 2017, reflecting unfavorable foreign exchange, an increase in R&D project investments, compensation-related costs, and the inclusion of the Irish biologic therapeutics business acquired in 2017.

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 business 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, stand-up costs, 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 business 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 March 31, 2018 vs. three months ended April 2, 2017

Corporate expenses increased by $10 million, or 7%, in the three months ended March 31, 2018, compared with the three months ended April 2, 2017, primarily due to an increase in certain compensation costs not allocated to our operating segments.

Other unallocated expenses declined by $5 million, or 6%, in the three months ended March 31, 2018, compared with the three months ended April 2, 2017, primarily due to continued cost improvements and efficiencies in our manufacturing network, and lower global manufacturing and supply costs, partially offset by the unfavorable impact of foreign exchange.

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:

32 |

Table of Contents


•	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 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.

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 and vaccines 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 FDA and/or other regulatory authorities.

Certain significant items

Adjusted net income is calculated prior to considering 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 becoming an independent public company; 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.

^(a)

The effective tax rate on adjusted pretax income is 18.2% and 27.8% for the three months ended March 31, 2018, and April 2, 2017, respectively. The lower effective tax rate for the three months ended March 31, 2018, compared with the three months ended April 2, 2017, was primarily attributable to (i) the reduction of the U.S. federal corporate income tax rate from 35% to 21%, effective January 1, 2018, pursuant to the Tax Act, (ii) changes in the jurisdictional mix of earnings, which includes the impact of the location of earnings as well as repatriation costs, (iii) a $8 million and $5 million discrete tax benefit recorded in the first quarter of 2018 and 2017, respectively, related to the excess tax benefits for share-based payments, and (iv) a $3 million discrete tax benefit recorded in the first quarter of 2018 related to a remeasurement of deferred taxes as a result of a change in non-U.S. statutory tax rates.

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

March 31, 2018 vs. December 31, 2017

For a discussion about the changes in Cash and cash equivalents, Short-term borrowings, Current portion of long-term debt, 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 the timing of customer collections.

The net changes in Deferred tax assets, Deferred tax liabilities, Income taxes payable and Other taxes payable primarily reflect adjustments to the accrual for the income tax provision for the first quarter of 2018, as well as the impact of the remeasurement of deferred taxes as a result of a change in tax rates. See Notes to Condensed Consolidated Financial Statements— Note 7. Income Taxes.

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

Accrued compensation and related items decreased primarily due to payment of 2017 annual bonuses to eligible employees and 2017 employee savings plan contributions, partially offset by the pro rata accrual of similar items for 2018.

Accrued expenses and Other current liabilities decreased primarily as a result of payment of accrued expenses, including accrued interest and accrued contract rebates.

Operating activities

Three months ended March 31, 2018 vs. three months ended April 2, 2017

Net cash provided by operating activities was $389 million for the three months ended March 31, 2018, compared with net cash provided by operating activities of $119 million for the three months ended April 2, 2017. The increase in operating cash flows was primarily attributable to higher income before allocation to noncontrolling interests and the timing of receipts and payments in the ordinary course of business.

Investing activities

Three months ended March 31, 2018 vs. three months ended April 2, 2017

Our net cash used in investing activities was $45 million for the three months ended March 31, 2018, compared with net cash used in investing activities of $48 million for the three months ended April 2, 2017. The net cash used in investing activities for 2018 was due primarily to purchases of property, plant and equipment, partially offset by proceeds from the 2017 sale of our manufacturing site in Guarulhos, Brazil. The net cash used in investing activities for 2017 was due primarily to purchases of property, plant and equipment, the acquisition of a Norwegian fish vaccination company, and an investment related to a European livestock monitoring company.

Financing activities

Three months ended March 31, 2018 vs. three months ended April 2, 2017

Our net cash used in financing activities was $262 million for the three months ended March 31, 2018, compared with net cash used in financing activities of $176 million for the three months ended April 2, 2017. The net cash used in financing activities for 2018 and 2017 was primarily attributable to the purchase of treasury shares and the payment of dividends.

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 meeting 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:



	March 31,		December 31,
(MILLIONS OF DOLLARS)	2018		2017
Cash and cash equivalents	$	1,654	$	1,564
Accounts receivable, net^(a)	943		998
Long-term debt	4,954		4,953
Working capital	3,267		3,123
Ratio of current assets to current liabilities	4.27:1		3.85:1

^(a)

Accounts receivable are usually collected over a period of 60 to 90 days. For the three months ended March 31, 2018, compared with December 31, 2017, 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

We were in compliance with all financial covenants as of March 31, 2018 and December 31, 2017. There were no amounts drawn under the credit facility as of March 31, 2018 or December 31, 2017.

Domestic and international short-term funds

Many of our operations are conducted outside the United States. The amount of funds held in the United States 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). Repatriation of overseas funds can result in additional U.S. state income taxes, foreign withholding taxes and currency gains and losses. We recorded U.S. deferred tax liabilities associated with the one-time mandatory deemed repatriation tax imposed by the Tax Act to the extent amounts earned overseas are expected to be indefinitely reinvested outside the United States, no accrual for foreign withholding taxes and currency gains and losses is provided.

Global economic conditions

The challenging economic environment has 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 a further economic downturn would not impact our ability to obtain financing in the future.

Debt

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 and 2017 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 and 2017 senior notes may be declared immediately due and payable.

Pursuant to the indenture, we are able to redeem the 2013, 2015 and 2017 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. 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 and 2017 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 and 2017 senior notes at a price equal to 101% of the aggregate principal amount of the 2013, 2015 and 2017 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 2016, the company's Board of Directors authorized a $1.5 billion share repurchase program. 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 three months ended March 31, 2018, approximately 2 million shares were repurchased. As of March 31, 2018, there was approximately $810 million remaining under this authorization.

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 March 31, 2018, or December 31, 2017, recorded amounts for the estimated fair value of these indemnifications are not significant.

New accounting standards

Recently Issued Accounting Standards Not Adopted as of March 31, 2018.

39 |

Table of Contents

In February 2016, the FASB issued an accounting standards update which requires lessees to recognize most leases on the balance sheet with a corresponding right of use asset. Leases will be classified as financing or operating which will drive the expense recognition pattern. For lessees, the income statement presentation and expense recognition pattern for financing and operating leases is similar to the current model for capital and operating leases, respectively. Companies may elect to exclude short-term leases. The update also requires additional disclosures that will better enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. We plan to adopt this guidance as of January 1, 2019, the required effective date, for annual and interim reporting periods. The new standard requires a modified retrospective adoption approach, at the beginning of the earliest comparative period presented in the financial statements. We have selected a lease accounting system and are currently evaluating our lease contracts, accounting policy elections, and the impact of adoption on our consolidated financial statements. While we do not expect adoption of the standard to have a significant impact on our Consolidated Statements of Income, the impact on the assets and liabilities within our Consolidated Balance Sheet may be material.

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 our 2018 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, 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, our agreements with Pfizer, 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 potentially inaccurate assumptions. Among the factors that could cause actual results to differ materially from past results and future plans and projected future results are the following:


•	emerging restrictions and bans on the use of antibacterials in food-producing animals;


•	perceived adverse effects on human health linked to the consumption of food derived from animals that utilize our products;


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


•	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;


•	an outbreak of infectious disease carried by animals;


•	consolidation of our customers and distributors negatively affecting the pricing of our products;


•	adverse weather conditions and the availability of natural resources;


•	adverse global economic conditions;


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


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


•	quarterly fluctuations in demand and costs;


•	governmental laws and regulations affecting domestic and foreign operations, including without limitation, tax obligations and changes affecting the tax treatment by the United States of income earned outside the United States 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. 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

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 renminbi, euro, and U.K. 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 March 31, 2018, 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 March 31, 2018, 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 $22 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 $29 million. For additional details, see Notes to Condensed Consolidated Financial Statements— Note 8B. Financial Instruments: Derivative Financial Instruments— Foreign Exchange Risk.

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 commercial paper and revolving credit facility will be exposed to interest rate fluctuations. At March 31, 2018, there were no commercial paper borrowings outstanding and no outstanding principal balance under our revolving credit facility. See Notes to Condensed Consolidated Financial Statements— Note 8B. Financial Instruments: Derivative Financial Instruments— Interest Rate Risk.


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 March 31, 2018, 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 2017 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 2017 Annual Report on Form 10-K.

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 United States 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, the European Commission opened formal investigations to examine whether decisions by the tax authorities in certain European countries, including Belgium, comply with European Union rules on state aid. In the case of Belgium, the European Commission concluded on January 11, 2016, that the excess profits ruling violates the European Union’s state aid rules.

In addition, on June 20, 2016, the Member States of the European Union adopted the anti-tax-avoidance directive proposed on January 28, 2016, which is designed to provide uniform implementation of Base Erosion and Profits Shifting measures and other minimum taxation standards across Member States. The Member States are required to implement all components of the directive by January 1, 2020. Once enacted by the Member States, the results of the directive could have an impact on our effective tax rate. In October 2016, the European Union also introduced a proposal to impose a uniform set of rules on taxing corporate profits, known as the Common Consolidated Corporate Tax Base. This proposal is still under consideration and may have an impact to our effective tax rate.

On December 22, 2017, President Trump signed into law the Tax Cuts and Jobs Act (the Tax Act) effective January 1, 2018. Some notable provisions of the Tax Act include a reduction of the corporate income tax rate from 35% to 21%, and a change from a worldwide system with deferral to a territorial tax system, which includes a one-time mandatory deemed repatriation tax, payable over eight years, on certain undistributed earnings of non-U.S. subsidiaries. As of December 31, 2017, the cumulative amount of non-U.S. undistributed earnings was approximately $4.5 billion, which includes an allocation of non-U.S. undistributed earnings as a result of the separation from Pfizer on June 24, 2013. Pursuant to the Staff Accounting Bulletin published by the Securities and Exchange Commission on December 22, 2017, addressing the challenges in accounting for the effects of the Tax Act in the period of enactment, companies must report provisional amounts for those specific income tax effects of the Tax Act for which the accounting is incomplete but a reasonable estimate can be determined. Those provisional amounts will be subject to adjustment during a measurement period of up to one year from the enactment date. The company is currently in the process of evaluating the full impact of this new legislation on its consolidated financial statements, and in the fourth quarter of 2017 recorded a provisional net charge of $212 million related to the one-time mandatory deemed repatriation tax, partially offset by the remeasurement of the deferred tax assets and liabilities, as of the date of enactment, due to the reduction in the U.S. federal corporate tax rate. A measurement-period adjustment was recorded in the first quarter of 2018 as a decrease to income tax expense of $2 million. 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, United Kingdom (UK) Prime Minister Theresa May formally notified the European Council of the UK’s intention to withdraw from the European Union, commonly referred to as “Brexit”, under Article 50 of the Treaty of Lisbon. The notice begins the two-year negotiation period to establish the withdrawal terms. If no agreement is reached after two years, the UK’s separation still becomes effective, unless the remaining European Union members unanimously agree to an extension. At this time, the impact of Brexit to our effective tax rate is 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 United States 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.
