ZOETIS INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS

(UNAUDITED)

1. Organization

Zoetis Inc. (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 four geographic regions: the United States (U.S.); Europe/Africa/Middle East (EuAfME); Canada/Latin America (CLAR); and Asia/Pacific (APAC).

We market our products in more than 120 countries, including developed markets and emerging markets. Our revenues are mostly generated in the U.S. and EuAfME. We have a diversified business, marketing products across 8 core species: cattle, swine, poultry, sheep and fish (collectively, livestock) and dogs, cats and horses (collectively, companion animals); and within 5 major product categories (anti-infectives, vaccines, parasiticides, medicated feed additives and other pharmaceuticals).

2. The Separation, Adjustments Associated with the Separation, Senior Notes Offering and Initial Public Offering

Pfizer Inc. (Pfizer) formed Zoetis to ultimately acquire, own, and operate the animal health business of Pfizer.

A. The Separation

In the first quarter of 2013, through a series of steps (collectively, the Separation), Pfizer transferred to us its subsidiaries holding substantially all of the assets and liabilities of its animal health business. In exchange, we transferred to Pfizer: (i) all of the issued and outstanding shares of our Class A common stock; (ii) all of the issued and outstanding shares of our Class B common stock; (iii) $1.0 billion in senior notes (see “Senior Notes Offering" below); and (iv) an amount of cash equal to substantially all of the net proceeds received in the senior notes offering (approximately $2.5 billion).

B. Adjustments Associated with the Separation

In connection with the Separation, certain animal health assets and liabilities included in the pre-Separation balance sheet were retained by Pfizer and certain non-animal health assets and liabilities (not included in the pre-Separation balance sheet) were transferred to Zoetis. The adjustments to the historical balance sheet of Zoetis (collectively, the Separation Adjustments) representing approximately $436 million of net liabilities retained by Pfizer, were primarily related to the following:

• The removal of inventories (approximately $74 million), property, plant and equipment (approximately $28 million) and miscellaneous other net liabilities of approximately $21 million associated with certain non-dedicated manufacturing sites that were retained by Pfizer;

• The addition of property, plant and equipment (approximately $56 million) associated with a non-dedicated manufacturing site that was transferred to us by Pfizer (and then leased back to Pfizer under operating leases), the removal of the inventory (approximately $46 million) and net other assets (approximately $4 million) at that site as these assets were retained by Pfizer;

• The addition of net benefit plan liabilities (approximately $25 million);

• The elimination of (i) noncurrent deferred tax assets (some of which were included within noncurrent deferred tax liabilities due to jurisdictional netting) related to net operating loss and tax credit carryforwards; (ii) net tax liabilities associated with uncertain tax positions; (iii) noncurrent deferred tax liabilities relating to deferred income taxes on unremitted earnings; and (iv) other allocated net tax assets, all of which (approximately $49 million in net tax asset accounts) were retained by Pfizer;

• The addition of (i) noncurrent deferred tax assets (approximately $8 million, some of which were included within noncurrent deferred tax liabilities due to jurisdictional netting) related to net benefit plan liabilities transferred to us by Pfizer; (ii) noncurrent deferred tax assets (approximately $2 million) related to net operating loss and tax credit carryforwards; and (iii) noncurrent deferred tax liabilities (approximately $2 million) related to property, plant and equipment transferred to us by Pfizer;

• The elimination of allocated long-term debt (approximately $582 million), allocated accrued interest payable (approximately $16 million) and allocated unamortized deferred debt issuance costs (approximately $2 million) that were retained by Pfizer;

• Certain net financial assets retained by Pfizer of approximately $45 million;

• The removal of inventories (approximately $10 million), property plant and equipment (approximately $20 million) and other miscellaneous net assets (approximately $1 million) associated with Pfizer's animal health business in certain non-U.S. jurisdictions that have not transferred to us from Pfizer as of March 31, 2013; and

• The removal of miscellaneous other liabilities (approximately $52 million) and the addition of miscellaneous other assets (approximately $5 million).

The Separation Adjustment associated with Accumulated Other Comprehensive Income reflects the accumulated currency translation adjustment based on the actual legal entity structure of Zoetis.

C. Senior Notes Offering

In connection with the Separation, on January 28, 2013, we issued $3.65 billion aggregate principal amount of our senior notes (the senior notes offering) in a private placement, with an original issue discount of $10 million. For additional information, see Note 9D. Financial Instruments: Senior Notes Offering.

D. Initial Public Offering (IPO)

After the Separation, on February 6, 2013, an IPO of 99,015,000 shares of our Class A common stock (including the exercise of the underwriters' over-allotment option) at a price of $26.00 per share was completed. We did not receive any of the net proceeds from the IPO.

Immediately following the IPO, there were 99,015,000 outstanding shares of Class A common stock and 400,985,000 outstanding shares of Class B common stock. The rights of the holders of Class A common stock and Class B common stock are identical, except with respect to voting and conversion rights. The holders of Class A common stock and Class B common stock are each entitled to one vote per share for all matters submitted to a vote of stockholders other than with respect to the election of the Board of Directors. With respect to the election of directors, the holders of Class B common stock are entitled to ten votes per share, and the holders of Class A common stock are entitled to one vote per share. Each share of Class B common stock held by Pfizer or one of its subsidiaries is convertible into one share of Class A common stock at any time, but will not be convertible if held by any other holder. Currently, Pfizer owns 100% of our outstanding Class B common stock and no shares of our Class A common stock, giving Pfizer 80.2% of the economic interest and the combined voting power in shares of our outstanding common stock other than with respect to the election of Directors and 97.6% of the combined voting power of our outstanding common stock with respect to the election of Directors.

Pfizer has informed us that it may make a tax-free distribution to its shareholders of all or a portion of its remaining equity interest in us, which may include one or more distributions effected as a dividend to all Pfizer shareholders, one or more distributions in exchange for Pfizer shares or other securities, or any combination thereof. We refer to any such potential distribution as the Distribution. Pfizer has no obligation to pursue or consummate any further dispositions of its ownership interest in us, including through the Distribution, by any specified date or at all. 

In connection with the IPO, we entered into certain agreements that provide a framework for an ongoing relationship with Pfizer. For additional information, see Note 17B. Related Party Transactions: Agreements with Pfizer.

3. Basis of Presentation

The accompanying unaudited condensed consolidated and combined financial statements were prepared following the requirements of the Securities and Exchange Commission (SEC) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by accounting principles generally accepted in the United States of America (U.S. GAAP) can be condensed or omitted. Balance sheet amounts and operating results for subsidiaries operating outside the U.S. are as of and for the three-month periods ended February 24, 2013 and February 26, 2012.

Revenues, 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 and combined financial statements included in this Form 10-Q. The condensed consolidated and combined 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 combined financial statements and accompanying notes included in the Company’s 2012 Annual Report on Form 10-K.

A. Basis of Presentation Prior to the Separation

Prior to the Separation, the combined financial statements were derived from the consolidated financial statements and accounting records of Pfizer and included allocations for direct costs and indirect costs attributable to the operations of the animal health business of Pfizer. The pre-Separation financial statements and activities do not purport to reflect what the results of operations, comprehensive income/(loss), financial position, equity or cash flows would have been had we operated as a standalone public company during the period presented.

• The condensed combined statements of income for the three months ended April 1, 2012 and the pre-Separation period in the condensed consolidated statement of income for the three months ended March 31, 2013 include allocations from certain support functions (Enabling Functions) that are provided on a centralized basis within Pfizer, such as expenses for business technology, facilities, legal, finance, human resources, and, to a lesser extent, business development, public affairs and procurement, among others, as Pfizer does not routinely allocate these costs to any of its business units. These allocations are based on either a specific identification basis or, when specific identification is not practicable, proportional allocation methods (e.g., using third-party sales, headcount, etc.), depending on the nature of the services.

We allocated the costs associated with business technology, facilities and human resources primarily using proportional allocation methods and for legal and finance, primarily using specific identification. In all cases, for support function costs where proportional allocation methods were used, we determined whether the costs are primarily influenced by headcount (such as a significant majority of facilities and human resources costs) or by the size of the business (such as most business technology costs), and we also determined whether the associated scope of those services provided are global, regional or local. Based on those analyses, we then allocated the costs based on our share of worldwide revenues, domestic revenues, international revenues, regional revenues, country revenues, worldwide headcount, country headcount or site headcount, as appropriate.

7 |

As a result, costs associated with business technology and legal that were not specifically identified were mostly allocated based on revenue drivers and, to a lesser extent, based on headcount drivers; costs associated with finance that were not specifically identified were all allocated based on revenue drivers; and costs associated with facilities and human resources that were not specifically identified were predominantly allocated based on headcount drivers.

• The condensed combined statement of income for the three months ended April 1, 2012 and the pre-Separation period in the condensed consolidated statement of income for the three months ended March 31, 2013 include allocations of certain manufacturing and supply costs incurred by manufacturing plants that are shared with other Pfizer business units, Pfizer’s global external supply group and Pfizer’s global logistics and support group (collectively, Pfizer Global Supply, or PGS). These costs may include manufacturing variances and changes in the standard costs of inventory, among others, as Pfizer does not routinely allocate these costs to any of its business units. These allocations are based on either a specific identification basis or, when specific identification is not practicable, proportional allocation methods, such as animal health identified manufacturing costs, depending on the nature of the costs.

• The condensed combined statement of income for the three months ended April 1, 2012 and the pre-Separation period in the condensed consolidated statement of income for the three months ended March 31, 2013 also include allocations from the Enabling Functions and PGS for restructuring charges, integration costs, additional depreciation associated with asset restructuring and implementation costs, as Pfizer does not routinely allocate these costs to any of its business units. For additional information about allocations of restructuring charges and other costs associated with acquisitions and cost-reduction/productivity initiatives, see Note 5. Restructuring Charges and Other Costs Associated with Acquisitions and Cost-Reduction/Productivity Initiatives.

• The condensed combined statement of income for the three months ended April 1, 2012 and the pre-Separation period in the condensed consolidated statement of income for the three months ended March 31, 2013 include an allocation of share-based compensation expense and certain other compensation expense items, such as certain fringe benefit expenses, maintained on a centralized basis within Pfizer, as Pfizer does not routinely allocate these costs to any of its business units. For additional information about allocations of share-based payments, see Note 13. Share-Based Payments.

• The condensed combined balance sheet as of December 31, 2012 reflects all of the assets and liabilities of Pfizer that are either specifically identifiable or are directly attributable to Zoetis and its operations. For benefit plans, the combined balance sheets only include the assets and liabilities of benefit plans dedicated to animal health employees. For debt, see below.

• The condensed combined balance sheet as of December 31, 2012 includes an allocation of long-term debt from Pfizer that was issued to partially finance the acquisition of Wyeth (including Fort Dodge Animal Health (FDAH)). The debt and associated interest-related expenses, including the effect of hedging activities, have been allocated on a pro-rata basis using the deemed acquisition cost of FDAH as a percentage of the total acquisition cost of Wyeth. No other allocations of debt have been made as none are specifically related to our operations.

The allocated expenses from Pfizer include the items noted below for the pre-Separation period in 2013 and the first quarter of 2012.

• Enabling Functions operating expenses––$11 million in 2013 and $79 million in 2012 ($1 million in Cost of sales in 2012; $11 million and $63 million in Selling, general and administrative expenses in 2013 and 2012, respectively; and$15 million in Research and development expenses in 2012).

• PGS manufacturing costs—approximately $2 million in 2013 and $7 million in 2012 (in Cost of sales).

• Restructuring charges and certain acquisition-related costs—$18 million in 2012 (in Restructuring charges and certain acquisition-related costs).

• Other costs associated with cost reduction/productivity initiatives—additional depreciation associated with asset restructuring—$2 million in 2013 (in Selling, general and administrative expenses) and $9 million in 2012 (in Research and development expenses).

• Other costs associated with cost reduction/productivity initiatives—implementation costs—$1 million in 2013 and $1 million in 2012 (in Selling, general and administrative expenses).

• Share-based compensation expense—approximately $3 million in 2013 and $8 million in 2012 ($1 million and $2 million in Cost of sales in 2013 and 2012, respectively; $2 million and $5 million in Selling, general and administrative expenses in 2013 and 2012, respectively; and $1 million in Research and development expenses in 2012).

• Compensation-related expenses—approximately $1 million in 2013 and $14 million in 2012 ($5 million in Cost of sales in 2012; $1 million and $6 million in Selling, general and administrative expenses in 2013 and 2012, respectively; and $3 million in Research and development expenses in 2012).

• Interest expense—approximately $2 million in 2013 and $8 million in 2012.

The income tax provision in the condensed combined statement of income was calculated as if Zoetis filed a separate return.

Management believes that the allocations are a reasonable reflection of the services received or the costs incurred on behalf of Zoetis and its operations and that the condensed combined statement of income for the three months ended April 1, 2012 and the pre-Separation period in the condensed consolidated statement of income for the three months ended March 31, 2013.

Prior to the Separation, we participated in Pfizer's centralized cash management system and generally all excess cash was transferred to Pfizer on a daily basis. Cash disbursements for operations and/or investing activities were funded as needed by Pfizer. We had also participated in

Pfizer's centralized hedging and offsetting programs. As such, in the combined statement of income for the three months ended April 1, 2012, we include the impact of Pfizer's derivative financial instruments used for offsetting changes in foreign currency rates, net of the related foreign exchange gains and losses for the portion that is deemed to be associated with the animal health operations. Such gains and losses were not material to the combined financial statement for the period presented.

All balances and transactions among Zoetis and Pfizer and its subsidiaries, which can include dividends as well as intercompany activities, are shown in Business unit equity in the combined balance sheet as of December 31, 2012. As the books and records of Zoetis were not kept on a separate company basis, the determination of the average net balance due to or from Pfizer is not practicable.

B. Basis of Presentation After the Separation

The unaudited condensed consolidated financial statements as of and for the three months ended March 31, 2013 comprise the following: (i) the results of operations, comprehensive income, and cash flow amounts for the period prior to the Separation (see above), which includes allocations for direct costs and indirect costs attributable to the operations of the animal health business and (ii) the amounts for the period after the Separation, which reflect the results of operations, comprehensive income, financial position, equity and cash flows resulting from our operation as a standalone public company.

The income tax provision prepared after the Separation is based on the actual legal entity structure of Zoetis, with certain accommodations pursuant to a tax matters agreement. For additional information, see Note 17B. Related Party Transactions: Agreements with Pfizer.

4. Significant Accounting Policies

A. New Accounting Standards

There were no new accounting standards adopted during the first quarter of 2013.

B. Fair Value

Our fair value methodologies depend on the following types of inputs:

• Quoted prices for identical assets or liabilities in active markets (Level 1 inputs).

• Quoted prices for similar assets or liabilities in active markets or quoted prices for identical or similar assets or liabilities in markets that are not active or are directly or indirectly observable (Level 2 inputs).

• Unobservable inputs that reflect estimates and assumptions (Level 3 inputs).

A single estimate of fair value can result from a complex series of judgments about future events and uncertainties and can rely heavily on estimates and assumptions.

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

We incurred significant costs in connection with Pfizer’s cost-reduction initiatives (several programs initiated since 2005), and the acquisitions of Fort Dodge Animal Health (FDAH) on October 15, 2009 and King Animal Health (KAH) on January 31, 2011.

For example:

• in connection with the 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; and

• 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, 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, as well as functions such as business technology, shared services and corporate operations.

7. Income Taxes

A. Taxes on Income

For the three months ended March 31, 2013, the effective tax rate decreased to 27.1% from 34.5% for the three months ended April 1, 2012. The lower rate was primarily attributable to:

• incentive tax rulings in Belgium, effective December 1, 2012, and Singapore, effective October 29, 2012;

• changes in the jurisdictional mix of earnings, which includes the impact of the location of earnings as well as repatriation costs; and

• a $2 million discrete income tax benefit during the first quarter of 2013 related to the 2012 U.S. research and development tax credit, which was retroactively extended on January 3, 2013.

As of the Separation date, we operate under a new standalone legal entity structure. In connection with the Separation, adjustments have been made to the income tax accounts. See Note 2B. The Separation, Adjustments Associated with the Separation, Senior Notes Offering and Initial Public Offering: Adjustments Associated with the Separation.

B. Tax Matters Agreement

In connection with the Separation, we entered into a tax matters agreement with Pfizer that governs the parties' respective rights, responsibilities and obligations with respect to tax liabilities and benefits, tax attributes, the preparation and filing of tax returns, the control of audits and other tax proceedings and other matters regarding taxes. For additional information, see below and Note 17B. Related Party Transactions: Agreements with Pfizer.

In connection with this agreement and the Separation, the activity in our income tax accounts reflects Separation Adjustments, including significant adjustments to the deferred income tax asset and liability accounts and the tax liabilities associated with uncertain tax positions. For additional information, see below and Note 2B. The Separation, Adjustments Associated with the Separation, Senior Notes Offering and Initial Public Offering: Adjustments Associated with the Separation.

In general, under the agreement:

• Pfizer will be responsible for any U.S. federal, state, local or foreign income taxes and any U.S. state or local non-income taxes (and any related interest, penalties or audit adjustments and including those taxes attributable to our business) reportable on a consolidated, combined or unitary return that includes Pfizer or any of its subsidiaries (and us and/or any of our subsidiaries) for any periods or portions thereof ending on or prior to December 31, 2012. We will be responsible for the portion of any such taxes for periods or portions thereof beginning on or after January 1, 2013, as would be applicable to us if we filed the relevant tax returns on a standalone basis.

• We will be responsible for any U.S. federal, state, local or foreign income taxes and any U.S. state or local non-income taxes (and any related interest, penalties or audit adjustments) that are reportable on returns that include only us and/or any of our subsidiaries, for all tax periods whether before or after the completion of the Separation.

• Pfizer will be responsible for certain specified foreign taxes directly resulting from certain aspects of the Separation.

We will not generally be entitled to receive payment from Pfizer in respect of any of our tax attributes or tax benefits or any reduction of taxes of Pfizer. Neither party's obligations under the agreement will be limited in amount or subject to any cap. The agreement also assigns responsibilities for administrative matters, such as the filing of returns, payment of taxes due, retention of records and conduct of audits, examinations or similar proceedings. In addition, the agreement provides for cooperation and information sharing with respect to tax matters.

Pfizer will be primarily responsible for preparing and filing any tax return with respect to the Pfizer affiliated group for U.S. federal income tax purposes and with respect to any consolidated, combined, unitary or similar group for U.S. state or local or foreign income tax purposes or U.S. state or local non-income tax purposes that includes Pfizer or any of its subsidiaries, including those that also include us and/or any of our subsidiaries. We will generally be responsible for preparing and filing any tax returns that include only us and/or any of our subsidiaries.

The party responsible for preparing and filing a given tax return will generally have exclusive authority to control tax contests related to any such tax return.

C. Deferred Taxes

As of March 31, 2013, the total net deferred income tax liability of $192 million is included in Current deferred tax assets ($83 million), Noncurrent deferred tax assets ($63 million), Other current liabilities ($1 million) and Noncurrent deferred tax liabilities ($337 million).

As of December 31, 2012, the total net deferred income tax liability of $8 million is included in Current deferred tax assets ($101 million), Noncurrent deferred tax assets ($216 million), Other current liabilities ($2 million) and Noncurrent deferred tax liabilities ($323 million).

The significant increase in the total net deferred tax liability from December 31, 2012 to March 31, 2013 is primarily attributable to the Separation Adjustments, predominantly related to deferred tax assets associated with net operating loss/credit carry forwards and deferred tax liabilities associated with unremitted earnings that were retained by Pfizer. See Note 2B. The Separation, Adjustments Associated with the Separation, Senior Notes Offering and Initial Public Offering: Adjustments Associated with the Separation.

11 |

D. Tax Contingencies

As of March 31, 2013, the tax liabilities associated with uncertain tax positions of $32 million (exclusive of interest related to uncertain tax positions of $8 million) were included in Noncurrent deferred tax assets ($6 million) and Other taxes payable ($26 million).

As of December 31, 2012, the tax liabilities associated with uncertain tax positions of $144 million (exclusive of interest related to uncertain tax positions of $17 million) were included in Noncurrent deferred tax assets ($6 million) and Other taxes payable ($138 million).

The significant decrease in the tax liabilities associated with uncertain tax positions from December 31, 2012 to March 31, 2013 is primarily attributable to the Separation Adjustments predominantly related to liabilities retained by Pfizer. See Note 2B. The Separation, Adjustments Associated with the Separation, Senior Notes Offering and Initial Public Offering: Adjustments Associated with the Separation.

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. Accumulated Other Comprehensive Loss

Changes, net of tax, in accumulated other comprehensive loss follow:

	Currency Translation						Accumulated
	Adjustment			Benefit Plans			Other
	Net Unrealized			Actuarial			Comprehensive
(MILLIONS OF DOLLARS)	Gains/(Losses)			Losses(a)			Income/(Loss)

Separation adjustments(b)	22			—			22
Balance, March 31, 2013	$	(114	)	$	(7	)	$	(121	)

^(a) Actuarial losses for the three months ended March 31, 2013 include adjustments for net pension obligations reflected in the historical financial statements of Zoetis, but not transferred by Pfizer to Zoetis as of March 31, 2013. See Note 12. Benefit Plans.

^(b) See Note 2B. The Separation, Adjustments Associated with the Separation, Senior Notes Offering and Initial Public Offering: Adjustments Associated with the Separation.

9. Financial Instruments

A. Credit Facility

In December 2012, we entered into a revolving credit agreement with a syndicate of banks providing for a five-year $1.0 billion senior unsecured revolving credit facility (the credit facility), which became effective in February 2013 upon the completion of the IPO and expires in December 2017. 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 4.35:1 for fiscal year 2013, 3.95:1 for fiscal year 2014, 3.50:1 for fiscal year 2015 and 3.00:1 thereafter. 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. Subject to certain conditions, we have the right to increase the credit facility to up to $1.5 billion. There are currently no borrowings outstanding.

B. Commercial Paper Program

In February 2013, we entered into a commercial paper program with a capacity of up to $1.0 billion. As of March 31, 2013, no commercial paper has been issued under this program.

C. Short-Term Borrowings

There were short-term borrowings of $6 million as of March 31, 2013. As of December 31, 2012 the current portion of allocated debt from Pfizer was $73 million. The weighted-average interest rate on short-term borrowings outstanding, including the current portion of allocated debt, was 3.0% and 3.7% as of March 31, 2013 and December 31, 2012, respectively.

D. Senior Notes Offering

On January 28, 2013, we issued $3.65 billion aggregate principal amount of our senior notes (the senior notes offering) in a private placement, with an original issue discount of $10 million. The senior notes are comprised of $400 million aggregate principal amount of our 1.150% senior notes due 2016, $750 million aggregate principal amount of our 1.875% Senior Notes due 2018, $1.35 billion aggregate principal amount of our 3.250% senior notes due 2023 and $1.15 billion aggregate principal amount of our 4.700% senior notes due 2043.

12 |

We sold $2.65 billion aggregate principal amount of our senior notes through the initial purchasers in the senior notes offering and Pfizer transferred $1.0 billion aggregate principal amount of our senior notes to certain of the initial purchasers, who sold such senior notes in the senior notes offering.

The 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 senior notes may be declared immediately due and payable.

Pursuant to the indenture, we are able to redeem the 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 2023 notes 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 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 purchase each of the senior notes at a price equal to 101% of the aggregate principal amount of the senior notes together with accrued and unpaid interest to, but excluding, the date of repurchase.

The components of our long-term debt follow:

	March 31,			December 31,
(MILLIONS OF DOLLARS)	2013			2012
Allocated long-term debt	$	—		$	509
1.150% Senior Notes due 2016	400			—

	3,650			509
Unamortized debt discount	(10		)	—
Long-term debt / Allocated long-term debt	$	3,640		$	509

As of March 31, 2013, the fair value of our senior notes was $3,604 million 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’s credit rating (Level 2 inputs). At December 31, 2012, the fair value of our allocated long-term debt was $732 million, and has been determined using a third-party matrix-pricing model that uses significant inputs derived from or corroborated by observable market data and Pfizer’s credit rating (Level 2 inputs). See Note 4B. Significant Accounting Policies: Fair Value. The fair value of the allocated long-term debt as of December 31, 2012 does not purport to reflect the fair value that might have been determined if Zoetis had operated as a standalone public company for the periods presented or if we had used Zoetis’s credit rating in the calculation.

The principal amount of long-term debt outstanding as of March 31, 2013 matures in the following years:

Maturities	$	—	$	—	$	400	$	—	$	3,250	$	3,650

E. Derivative Financial Instruments

Foreign Exchange Risk

A significant portion of our revenues, earnings and net investment in foreign affiliates is exposed to changes in foreign exchange rates. Prior to the IPO, as a business unit of Pfizer and under Pfizer's global cash management system, our foreign exchange risk was managed through Pfizer. Following the Separation, we seek to manage our foreign exchange risk, in part, through operational means, including managing same-currency revenues 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. As of March 31, 2013, the aggregate notional amount of foreign exchange derivative financial instruments offsetting foreign currency exposures was $936 million. The derivative financial instruments primarily offset exposures in the euro, the Brazilian real and the Australian dollar. The vast majority of the foreign exchange derivative financial instruments mature within 60 days and all mature within 180 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.

Fair Value of Derivative Instruments

13 |

The location and fair values of derivative instruments not designated as hedging instruments at March 31, 2013 are as follows:

(MILLIONS OF DOLLARS)	Balance Sheet Location	Fair Value of Derivatives
Foreign currency forward-exchange contracts	Other current assets	$	2
Foreign currency forward-exchange contracts	Other current liabilities	(1		)
Total foreign currency forward-exchange contracts		$	1

We use a market approach in valuing financial instruments on a recurring basis. Our derivative financial instruments measured at fair value on a recurring basis use Level 2 inputs in the calculation of fair value. See Note 4B. Significant Accounting Policies: Fair Value.

The net gains incurred on foreign currency forward-exchange contracts not designated as hedging instruments were $6 million for the three months ended March 31, 2013 and are recorded in Other (income)/deductions—net.

10. Inventories

The components of inventory follow:

	March 31,		December 31,
(MILLIONS OF DOLLARS)	2013		2012

Work-in-process	205		332
Raw materials and supplies	216		214
Inventories(a)	$	1,120	$	1,345

^(a)  Inventory levels decreased in 2013 as a result of $136 million of Separation Adjustments (see Note 2B. The Separation, Adjustments Associated with the Separation, Senior Notes Offering and Initial Public Offering: Adjustments Associated with the Separation), as well as operational reductions.

11. Goodwill and Other Intangible Assets

C. Amortization

Amortization expense related to 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 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 $16 million for both the first quarter of 2013 and 2012.

12. Benefit Plans

Prior to the Separation from Pfizer, employees who met certain eligibility requirements participated in various defined benefit pension plans and postretirement plans administered and sponsored by Pfizer. Effective December 31, 2012, our employees ceased to participate in the Pfizer U.S. qualified defined benefit and U.S. retiree medical plans, and liabilities associated with our employees under these plans were retained by Pfizer. Pfizer will continue crediting certain employees' service with us generally through December 31, 2017 (or termination of employment from us, if earlier) for certain early retirement benefits with respect to the defined benefit pension plan and the retiree medical plan. Pension and postretirement benefit expense associated with the extended service for certain employees in the U.S. plans, totaled approximately $2 million for the three months endedMarch 31, 2013.

As part of the Separation, certain Separation Adjustments (see Note 2B. The Separation, Adjustments Associated with the Separation, Senior Notes Offering and Initial Public Offering: Adjustments Associated with the Separation) were made to transfer the assets and liabilities of certain international defined benefit pension plans including Austria, France, Germany, Greece, Italy, Mexico, South Africa, Taiwan and Thailand, to Zoetis in the first quarter of 2013, and we assumed the liabilities allocable to employees transferring to us. Prior to the Separation, these benefit plans were accounted for as multi-employer plans. Also, as part of the Separation Adjustments, a benefit plan in Germany was retained by Pfizer. The net obligation of the transferred plans totaled $25 million. At March 31, 2013, the projected benefit obligation and fair value of plan assets of the dedicated international pension plans in the Netherlands, Germany, India and Korea, as well as those plans transferred in the 2013 first quarter, were $72 million and $43 million, respectively. Estimated net pension obligations, of approximately $23 million, associated with additional defined benefit pension plans in certain international locations, are expected to be transferred to us later in 2013, in accordance with the applicable local separation agreements.

Pension expense associated with dedicated international pension plans was approximately $0.5 million for the three months endedMarch 31, 2013. Pension expense associated with international benefit plans accounted for as multi-employer plans was approximately $3 million for the three months endedMarch 31, 2013.

For the three months ended March 31, 2013, contributions to the dedicated international benefits plans and the international plans accounted for as multi-employer plans were $0.1 million and $2 million, respectively. We expect to contribute approximately $7 million to these plans in 2013.

13. Share-Based Payments

A. Zoetis 2013 Equity and Incentive Plan

In January 2013, the Zoetis 2013 Equity and Incentive Plan (Equity Plan) became effective. Awards under the Equity Plan may be in the form of stock options, or other stock-based awards, including awards of restricted stock, restricted stock units and performance share awards. The Equity Plan also provides for the grant of cash-based awards. The principal types of stock-based awards available under the Equity Plan may include, but are not limited to, the following:

• Stock Options. Stock options represent the right to purchase shares of our common stock within a specified period of time at a specified price. The exercise price for a stock option will be not less than 100% of the fair market value of the common stock on the date of grant. Stock options will have a contractual maximum term of ten years from the date of grant. Stock options granted may include those intended to be “incentive stock options” within the meaning of Section 422 of the Code.

• Restricted Stock and Restricted Stock Units (RSUs). Restricted stock is a share of our common stock that is subject to a risk of forfeiture or other restrictions that will lapse subject to the recipient's continued employment, the attainment of performance goals, or both. Restricted stock units represent the right to receive shares of our common stock in the future (or cash determined by reference to the value of our common stock), subject to the recipient's continued employment, the attainment of performance goals, or both.

• Performance-Based Awards. Performance awards will require satisfaction of pre-established performance goals, consisting of one or more business criteria and a targeted performance level with respect to such criteria as a condition of awards vesting or being settled. Performance may be measured over a period of any length specified.

• Other Equity-Based or Cash-Based Awards. Our Compensation Committee is authorized to grant awards in the form of other equity-based awards or other cash-based awards, as deemed to be consistent with the purposes of the Equity Plan. The maximum value of the aggregate payment to be paid to any participant with respect to cash-based awards under the Equity Plan in respect of an annual performance period will be $10 million.

In order to provide long-term incentives to, and facilitate the retention of, our employees, we granted stock options (or other awards as appropriate with respect to our employees in non-U.S. jurisdictions) and restricted stock units under the Equity Plan on January 31, 2013 and February 1, 2013, respectively, to 1,700 of our employees. These awards will vest on the third anniversary of the IPO.

B. Share-Based Compensation Expense

The components of share-based compensation expense follow:

	Three Months Ended
	March 31,		April 1,
(MILLIONS OF DOLLARS)	2013		2012
Stock option expense	$	2	$	—
RSU expense	1		—
Pfizer stock benefit plans—direct	8		6
Share-based compensation expense—direct	11		6
Share-based compensation expense—indirect	—		2
Share-based compensation expense—total	11		8

C. Stock Options

Stock options are accounted for using a fair-value-based method at the date of grant in the consolidated statement of income. 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.

All eligible employees may receive Zoetis stock option grants. Zoetis stock options granted vest after three years of continuous service from the grant date and have a contractual term of 10 years. In most cases, Zoetis stock options must be held for at least one year from the grant date before any vesting may occur. In the event of a divestiture or restructuring, Zoetis stock options held by impacted employees are immediately vested and are exercisable for a period from three months to their remaining term, depending on various conditions.

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 noted in the following table, shown at their weighted-average values:

16 |

	Three Months
	Ended
	March 31, 2013
Expected dividend yield(a)	1.0	%
Risk-free interest rate(b)	1.29	%
Expected stock price volatility(c)	28.2	%
Expected term(d) (years)	6.5

^(a)  Determined using a constant dividend yield during the expected term of the Zoetis stock option.

^(b) Determined using the interpolated yield on U.S. Treasury zero-coupon issues.

^(c) Determined using implied volatility.

^(d) Determined using expected exercise and post-vesting termination patterns.

The following table provides an analysis of stock option activity for the three months ended March 31, 2013:

					Weighted-Average
			Weighted-Average		Remaining	Aggregate
			Exercise Price		Contractual Term	Intrinsic Value(a)
	Shares		Per Share		(Years)	(MILLIONS)
Outstanding, December 31, 2012	—		$	—
Granted	2,928,422		26.00
Forfeited	(13,491	)	26.00
Outstanding, March 31, 2013	2,914,931		$	26.00	9.8	$	22
Exercisable, March 31, 2013	—		—		—	—

^(a)  Market price of underlying Zoetis common stock less exercise price.

The following table summarizes data related to stock option activity:

	Three Months
	Ended/As of
(MILLIONS OF DOLLARS, EXCEPT PER STOCK OPTION AMOUNTS)	March 31, 2013
Weighted-average grant date fair value per stock option	$	7.01
Total compensation cost related to nonvested stock options not yet recognized, pre-tax	$	19
Weighted-average period over which stock option compensation is expected to be recognized (years)	2.2

D. Restricted Stock Units (RSUs)

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 virtually all instances, the units vest after three years of continuous service from the grant date and the values determined using the fair-value-based method 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.

			Weighted-Average
			Grant Date
			Fair Value
	Shares		Per Share
Nonvested, December 31, 2012	—		$	—
Granted	793,456		26.00

Total compensation cost related to nonvested RSU awards not yet recognized, pre-tax	$	19
Weighted-average period over which RSU cost is expected to be recognized (years)	2.8

E. Treatment of Outstanding Pfizer Equity Awards

Following the IPO, the equity awards previously granted to our employees by Pfizer will continue to relate to Pfizer equity, as service with Zoetis will be counted as service with Pfizer for all purposes. Upon the Distribution, if any, assuming that Pfizer no longer owns a controlling interest in the company, it is intended that each outstanding, unvested Pfizer stock option will vest and, in general, Pfizer stock options will be exercisable for Pfizer common stock until the earliest to occur of (i) the three year anniversary of the Distribution, (ii) the option holder’s termination of employment from Zoetis or (iii) the expiration of the stock option grant. Upon the Distribution, if any, assuming that Pfizer no longer owns a controlling interest in the company, Pfizer will also accelerate the vesting and, in some cases, the settlement of certain other equity awards, subject, in each case, to the requirements of Section 409A of the U.S. Internal Revenue Code, the terms of the Pfizer Stock Plan and the applicable award agreements and any outstanding deferral elections. The accelerated vesting of the outstanding Pfizer equity awards will result in the recognition of additional expense. As of March 31, 2013, total unrecognized compensation costs related to these nonvested stock options, restricted stock units and performance awards under the Pfizer plans was approximately $28 million and the weighted-average period over which such awards are expected to be recognized is 1.8 years. The remaining period over which such awards will be recognized as expense may accelerate, depending on the timing or occurrence of a Distribution.

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 U.S. and in other countries.

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

18 |

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 heavily 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 heavily 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.

Roxarsone^®(3-Nitro)

We are defendants in nine actions involving approximately 140 plaintiffs that allege that the distribution of the medicated feed additive Roxarsone allegedly caused various diseases in the plaintiffs, including cancers and neurological diseases. Other defendants, including various poultry companies, are also named in these lawsuits. Compensatory and punitive damages are sought in unspecified amounts.

In September 2006, the Circuit Court of Washington County returned a defense verdict in one of the lawsuits, Mary Green, et al. v. Alpharma, Inc. et al. In 2008, this verdict was appealed and affirmed by the Arkansas Supreme Court. Certain summary judgments favoring the poultry company co-defendants in Mary Green, et al. v. Alpharma, Inc. et al. were reversed by the Arkansas Supreme Court in 2008. These claims were retried in 2009 and that trial also resulted in a defense verdict, which was affirmed by the Arkansas Supreme Court in April 2011. In October 2012, we entered into an agreement to resolve these cases. The resolution is subject to the execution of full releases or dismissals with prejudice by all of the claimants or our waiver of these requirements. The trial schedule has been suspended pending the outcome of the proposed settlement.

In June 2011, we announced that we would suspend sales in the U.S. of Roxarsone (3-Nitro) in response to a request by the U.S. FDA and subsequently stopped sales in several international markets.

Following our decision to suspend sales of Roxarsone (3-Nitro) in June 2011, Zhejiang Rongyao Chemical Co., Ltd., the supplier of certain materials used in the production of Roxarsone (3-Nitro), filed a lawsuit in the U.S. District Court for the District of New Jersey alleging that we are liable for damages it suffered as a result of the decision to suspend sales.

In September 2012, we were named as defendants in a purported class action in the Circuit Court of Arkansas County, Arkansas. The lawsuit alleges that the distribution of medicated feed additives, including Roxarsone, caused chickens to produce manure that contains an arsenical compound, which, when used as agricultural fertilizer by rice farmers, degrades into inorganic arsenic and allegedly caused contamination of rice produced by Arkansas farmers. Other defendants, including various poultry companies, are also named in these lawsuits. Compensatory damages, punitive damages, and attorney fees are sought in an unspecified amount. On March 4, 2013, plaintiffs filed a motion to dismiss the class action without prejudice. On March 7, 2013, the Court granted plaintiffs' motion and entered an order dismissing the case without prejudice.

PregSure^®

We have received in total approximately 80 claims in Europe and New Zealand seeking damages related to calves claimed to have died of Bovine Neonatal Pancytopenia (BNP) on farms where PregSure BVD, a vaccine against Bovine Virus Diarrhea (BVD) was used. BNP is a rare syndrome that first emerged in cattle in Europe in 2006. Studies of BNP suggest a potential association between the administration of PregSure and the development of BNP, although no causal connection has been established. The cause of BNP is not known.

In 2010, we voluntarily stopped sales of PregSure BVD in Europe, and recalled the product at wholesalers while investigations into possible causes of BNP continue. In 2011, after incidences of BNP were reported in New Zealand, we voluntarily withdrew the marketing authorization for PregSure throughout the world.

We have settled approximately 20 of these claims for amounts that are not material individually or in the aggregate. Investigations into possible causes of BNP continue and these settlements may not be representative of any future claims resolutions.

19 |

Advocin

On January 30, 2012, Bayer filed a complaint against Pfizer alleging infringement and inducement of infringement of Bayer patent US 5,756,506 covering, among other things, a process for treating bovine respiratory disease (BRD) by administering a single high dose of fluoroquinolone. The complaint was filed after Pfizer's product Advocin^® was approved as a single dose treatment of BRD, in addition to its previous approval as a multi-dose treatment of BRD. Bayer seeks a permanent injunction, damages and a recovery of attorney's fees, and has demanded a jury trial. Discovery has now concluded. We have filed motions for summary judgment of non-infringement and invalidity of the Bayer patent, which are currently pending before the Court.

Ulianopolis, Brazil

In February 2012, the Municipality of Ulianopolis (State of Para, Brazil) filed a complaint against Fort Dodge Saúde Animal Ltda. (FDSAL) and five other large companies alleging that waste sent to a local waste incinerator 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 waste 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 local incineration facility.

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, 2013, recorded amounts for the estimated fair value of these indemnifications are not significant.

16. Segment and Other Revenue Information

A. Segment Information

The animal health medicines and vaccines industry is characterized by meaningful differences in customer needs across different regions. As a result of these differences, among other things, we manage our operations through four geographic regions. Each operating segment has responsibility for its commercial activities. Within each of these regional 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.

Operating Segments

• The United States (U.S.).

• Europe/Africa/Middle East (EuAfME)—Includes, among others, the United Kingdom, Germany, France, Italy, Spain, Northern Europe and Central Europe as well as Russia, Turkey and South Africa.

• Canada/Latin America (CLAR)––Includes Canada, Brazil, Mexico, Central America and Other South America.

• Asia/Pacific (APAC)––Includes Australia, Japan, New Zealand, South Korea, India, China/Hong Kong, Northeast Asia, Southeast Asia and South Asia.

Our chief operating decision maker uses the revenues and earnings of the four operating segments, among other factors, for performance evaluation and resource allocation.

Other Costs and Business Activities

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

• R&D, which is generally responsible for research projects.

• Corporate, which is responsible for platform functions such as business technology, facilities, legal, finance, human resources, business development, public affairs and procurement, among others. These costs also include compensation costs and other miscellaneous operating expenses not charged to our operating segments, as well as interest income and expense.

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

20 |

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. As of March 31, 2013 and December 31, 2012, total assets were approximately $6.1 billion and $6.3 billion, respectively.

17. Related Party Transactions

Pfizer is a related party and these financial statements include transactions with Pfizer.

A. Pre-Separation Period

For the condensed combined statement of income for the three months ended April 1, 2012, the costs of goods manufactured in manufacturing plants that were shared with other Pfizer business units was approximately $110 million.

In the pre-Separation period, Pfizer provided significant corporate, manufacturing and shared services functions and resources to us. Our condensed combined financial statements as of and for the three months ended April 1, 2012 reflect an allocation of these costs. For further information about the cost allocations for these services and resources, see Note 3A. Basis of Presentation: Basis of Presentation Prior to the Separation. Management believes that these allocations are a reasonable reflection of the services received. However, these allocations may not reflect the expenses that would have been incurred if we had operated as a standalone public company for the period presented.

Pfizer uses a centralized approach to cash management and financing its operations. In the pre-Separation period, cash deposits were remitted to Pfizer on a regular basis and were reflected in business unit equity and, similarly, Zoetis's cash disbursements were funded through Pfizer's cash accounts and were reflected within Business unit equity.

22 |

B. Agreements with Pfizer

In connection with the Separation and IPO, we and Pfizer entered into agreements that provide a framework for our ongoing relationship with Pfizer, certain of which are described below.

• Global separation agreement. This agreement governs the relationship between Pfizer and us following the IPO and includes provisions related to the allocation of assets and liabilities, indemnification, delayed transfers and further assurances, mutual releases, insurance and certain covenants.

• Transitional services agreement. This agreement grants us the right to continue to use certain of Pfizer's services and resources related to our corporate functions, such as business technology, facilities, finance, human resources, public affairs and procurement, in exchange for mutually agreed-upon fees based on Pfizer's costs of providing these services.

• Tax matters agreement. This agreement governs ours and Pfizer's respective rights, responsibilities and obligations with respect to tax liabilities and benefits, tax attributes, the preparation and filing of tax returns, the control of audits and other tax proceedings and other matters regarding taxes. Pursuant to this agreement, we have also agreed to certain covenants that contain restrictions intended to preserve the tax-free status of certain transactions, and we have agreed to indemnify Pfizer and its affiliates against any and all tax-related liabilities incurred by them relating to these transactions to the extent caused by an acquisition of our stock or assets or by any other action undertaken by us.

• Research and development collaboration and license agreement. This agreement permits certain of our employees to be able to review a Pfizer database to identify compounds that may be of interest to the animal health field. Pfizer has granted to us an option to enter into a license agreement subject to certain restrictions and requirements and we will make payments to Pfizer.

• Employee matters agreement. This agreement governs ours and Pfizer's respective rights, responsibilities and obligations with respect to the following matters: employees and former employees (and their respective dependents and beneficiaries) who are or were associated with Pfizer, us or the parties' respective subsidiaries or affiliates; the allocation of assets and liabilities generally relating to employees, employment or service-related matters and employee benefit plans; and other human resources, employment and employee benefits matters.

• Master manufacturing and supply agreements. These two agreements govern our manufacturing and supply arrangements with Pfizer. Under one of these agreements, Pfizer will manufacture and supply us with animal health products. Under this agreement, our manufacturing and supply chain leadership will have oversight responsibility over product quality and other key aspects of the manufacturing process with respect to the Pfizer-supplied products. Under the other agreement, we will manufacture and supply certain human health products to Pfizer.

• Environmental matters agreement. This agreement governs the performance of remedial actions for liabilities allocated to each party under the global separation agreement; addresses our substitution for Pfizer with respect to animal health assets and remedial actions allocated to us (including substitution related to, for example, permits, financial assurances and consent orders); allows our conditional use of Pfizer's consultants and contractors to assist in the conduct of remedial actions; and addresses the exchange of related information between the parties. The agreement also sets forth standards of conduct for remedial activities at the co-located facilities: Guarulhos, Brazil; Catania, Italy; Hsinchu, Taiwan; and Kalamazoo, Michigan in the U.S. In addition, the agreement sets forth site-specific terms to govern conduct at several of these co-located facilities.

• Screening services agreement. This agreement requires us to provide certain high throughput screening services to Pfizer's R&D organization for which Pfizer pays to us agreed-upon fees.

• Intellectual property license agreements. Under these agreements (i) Pfizer and certain of its affiliates licensed to us and certain of our affiliates the right to use certain intellectual property rights in the animal health field; (ii) we licensed to Pfizer and certain of its affiliates certain rights to intellectual property in all fields outside of the animal health field; and (iii) Pfizer granted us rights with respect to certain trademarks and copyrighted works.

Following the Separation, we own, have access to or have the right to use substantially all of the resources that were used, or held for use, exclusively in Pfizer's animal health business, including the following:

• Intellectual Property. As part of the Separation, Pfizer assigned to us ownership of certain animal health related patents, pending patent applications, and trademark applications and registrations. In addition, Pfizer licensed to us the right to use certain intellectual property rights in the animal health field. We licensed to Pfizer the right to use certain of our trademarks and substantially all of our other intellectual property rights in the human health field and all other fields outside of animal health. In addition, Pfizer granted us a transitional license to use certain of Pfizer's trademarks and we granted Pfizer a transitional license to use certain of our trademarks for a period of time following the completion of the IPO.

• Manufacturing Facilities. Our global manufacturing network consists of 13 “anchor” manufacturing sites and 16 “satellite” manufacturing sites. Ownership of, or the existing leasehold interest in, these facilities were conveyed to us by Pfizer as part of the Separation. Among these 29 manufacturing sites is our facility in Guarulhos, Brazil, which we leased back to Pfizer. Certain of our products are currently manufactured at 14 manufacturing sites that were retained by Pfizer. The products manufactured by Pfizer at these sites and at our Guarulhos, Brazil facility continues to be supplied to us under the terms of a manufacturing and supply agreement we entered into with Pfizer.

23 |

• R&D Facilities. We have R&D operations co-located with certain of our manufacturing sites in Australia, Belgium, Brazil, Canada, China, Spain and the United States to facilitate the efficient transfer of production processes from our laboratories to manufacturing sites. In addition, we maintain R&D operations at non-manufacturing locations in Belgium, Brazil, India and the United States. As part of the Separation, Pfizer conveyed to us its interest in each of these R&D facilities, with the exception of our Mumbai, India facility, which we expect Pfizer to transfer to us for agreed upon cash consideration after the completion of the Separation, and, in the interim, we are leasing this facility from Pfizer.

• Employees. Following the Separation, we have approximately 9,500 employees worldwide. As part of the Separation, substantially all employees of Pfizer who were substantially dedicated to the animal health business became our employees. However, labor and employment laws or other business considerations in some jurisdictions delayed Pfizer from transferring to us employees who are substantially dedicated to the animal health business. In those instances, to the extent permissible under applicable law, we and Pfizer entered into mutually-acceptable arrangements, to provide for continued operation of the business until such time as the employees in those jurisdictions can be transitioned to us.

The amounts charged under each of the agreements with Pfizer for the three months ended March 31, 2103 were as follows:

	Three Months Ended
(MILLIONS OF DOLLARS)	March 31, 2013
Transitional services agreement	$	27
Master manufacturing and supply agreements	57
Employee matters agreement	31

In certain jurisdictions, while the Zoetis entities obtain appropriate registration and licensing, Pfizer entities purchase product from Zoetis entities and resell such product to the local Zoetis entity at cost. This activity is reflected in Receivable from Pfizer Inc. for the product Pfizer purchases from Zoetis entities and in Payable to Pfizer Inc. for the product purchased from such Pfizer entities by our local Zoetis entity. Amounts payable to Pfizer are included in Payable to Pfizer Inc. As of March 31, 2013, we remain part of Pfizer's consolidated U.S. tax returns, and therefore reflected our 2013 U.S. income taxes payable of $21 million as a payable to Pfizer. Additionally, as an 80.2% owner of our shares, we will pay Pfizer their portion of our dividend declared on March 28, 2013.

Review Report of Independent Registered Public Accounting Firm

The Board of Directors

Zoetis Inc:

We have reviewed the accompanying condensed consolidated balance sheet of Zoetis Inc. and subsidiaries (the Company) as of March 31, 2013, and the related condensed consolidated statements of income, comprehensive income, equity, and cash flows for the three-month period ended March 31, 2013 and the related condensed combined statements of income, comprehensive income, equity, and cash flows for the three-month period ended April 1, 2012. These condensed consolidated and condensed combined financial statements are the responsibility of the Company's management.

We conducted our reviews in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of 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 Public Company Accounting Oversight Board (United States), 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.

Based on our reviews, we are not aware of any material modifications that should be made to the condensed consolidated financial statements as of March 31, 2013 and for the three-month period ended March 31, 2013 and to the condensed combined financial statements for the three-month period ended April 1, 2012 referred to above for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with standards of the Public Company Accounting Oversight Board (United States), the combined balance sheet of Zoetis Inc. (the animal health business unit of Pfizer Inc.) as of December 31, 2012, and the related combined statements of income, comprehensive income, equity, and cash flows for the year then ended (not presented herein); and in our report dated March 28, 2013, we expressed an unqualified opinion on those combined financial statements. In our opinion, the information set forth in the accompanying condensed combined balance sheet as of December 31, 2012, is fairly stated, in all material respects, in relation to the combined balance sheet from which it has been derived.

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, as a business unit of Pfizer Inc. (Pfizer), we have been committed to enhancing the health of animals and bringing solutions to our customers who raise and care for them.

The animal health medicines and vaccines industry is characterized by meaningful differences in customer needs across different regions. As a result of these differences, among other things, we manage our operations through four geographic operating segments. 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. Our four operating segments are the United States (U.S.), Europe/Africa/Middle East (EuAfME), Canada/Latin America (CLAR) and Asia/Pacific (APAC). See Notes to Condensed Consolidated and Combined Financial Statements—Note 16. Segment and Other Revenue Information.

On February 6, 2013, an initial public offering (IPO) of our Class A common stock was completed, which represented approximately 19.8% of our total outstanding shares. Currently, Pfizer owns 100% of our outstanding Class B common stock and no shares of our Class A common stock, giving Pfizer 80.2% of the economic interest and the combined voting power in shares of our outstanding common stock other than with respect to the election of directors and 97.6% of the combined voting power of our outstanding common stock with respect to the election of directors. On February 1, 2013, our Class A common stock began trading on the New York Stock Exchange under the symbol “ZTS.” Prior to

26 |

and in connection with the IPO, we completed a $3.65 billion senior notes offering and Pfizer transferred to us substantially all of the assets and liabilities of their animal health business. We refer to the transactions to separate our business from Pfizer as described here and elsewhere in this quarterly report as the Separation.

Pfizer has informed us that it may make a tax-free distribution to its shareholders of all or a portion of its remaining equity interest in us, which may include one or more distributions effected as a dividend to all Pfizer shareholders, one or more distributions in exchange for Pfizer shares or other securities, or any combination thereof. We refer to any such potential distribution as the Distribution. Pfizer has no obligation to pursue or consummate any further dispositions of its ownership interest in us, including through the Distribution, by any specified date or at all. 

We directly market our products to livestock producers and veterinarians located in approximately 70 countries across North America, Europe, Africa, Asia, Australia and Latin 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 India, we believe we are the largest animal health medicines and vaccines business as measured by revenues 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 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.

A summary of our first quarter 2013 performance compared to the comparable 2012 period follows:

	Three Months Ended
	March 31,		April 1,		%
(MILLIONS OF DOLLARS)	2013		2012		Change
Revenues	$	1,090	$	1,047	4
Net income attributable to Zoetis	140		111		26

Our operating environment

Industry

The animal health industry, which focuses on both livestock and companion animals, is a growing industry that impacts billions of people worldwide. The primary livestock species for the production of animal protein are cattle (both beef and dairy), swine, poultry, sheep and fish. Livestock health and production are essential to meeting the growing demand for animal protein of a global population. Factors influencing growth in demand for livestock medicines and vaccines include:  

• human population growth and increasing standards of living, particularly in many emerging markets;

• increasing demand for improved nutrition, particularly animal protein;

• natural resource constraints, such as scarcity of arable land, fresh water and increased competition for cultivated land, resulting in fewer resources that will be available to meet this increased demand for animal protein; and

• increased focus on food safety.

The primary companion animal species are dogs, cats and horses. Industry sources indicate that companion animals improve the physical and emotional well-being of pet owners. Factors influencing growth in demand for companion animal medicines and vaccines include:  

• economic development and related increases in disposable income, particularly in many emerging markets;

• increasing pet ownership; and

• companion animals living longer, increasing medical treatment of companion animals and advances in companion animal medicines and vaccines.

Product development initiatives

Our future success depends on both our existing product portfolio and our pipeline of new products, including new products that we may develop through joint ventures and products that we are able to obtain through license or acquisition. We believe we are an industry leader in animal health R&D, with a track record of generating new products and brand lifecycle developments. The majority of our R&D programs focus on brand lifecycle development, which is defined as R&D programs that leverage existing animal health products by adding new species or claims, achieving approvals in new markets or creating new combinations and reformulations.

27 |

Perceptions of product quality, safety and reliability

We believe that animal health medicines and vaccines customers value high-quality manufacturing and reliability of supply. The importance of quality and safety concerns to pet owners, veterinarians and livestock producers also contributes to animal health brand loyalty, which we believe often continues after the loss of patent-based and regulatory exclusivity. We depend on positive perceptions of the safety and quality of our products, and animal health products generally, by our customers, veterinarians and end-users.

The issue of the potential transfer of increased antibacterial resistance in bacteria from food-producing animals to human pathogens, and the causality of that transfer, are the subject of global scientific and regulatory discussion. In some countries, this issue has led to government restrictions and bans on the use of specific antibacterials in some food-producing animals, regardless of the route of administration (topical, oral, intramuscular/subcutaneous injections, or intravenous). These restrictions are more prevalent in countries where animal protein is plentiful and governments are willing to take restrictive actions even when there is scientific uncertainty. Historically, antibacterials for livestock have represented a significant portion of our revenues. We cannot predict whether antibacterial resistance concerns will result in additional restrictions or bans, expanded regulations or public pressure to discontinue or reduce use of antibacterials in food-producing animals.

The overall economic environment

In addition to industry-specific factors, we, like other businesses, continue to face the effects of the current challenging economic environment. Growth in both the livestock and companion animal sectors is driven by overall economic development and related growth, particularly in many emerging markets. Certain of our customers and suppliers have been affected directly by the economic downturn, which decreases the demand for our products and hinders our ability to collect amounts due from customers.

The cost of medicines and vaccines to our livestock producer customers is small relative to other production costs, including feed, and the use of these products are intended to improve livestock producers’ economic outcomes. As a result, historically demand for our products has often been more stable than demand for other production inputs. Similarly, industry sources have reported that pet owners indicated a preference for reducing spending on other aspects of their lifestyle, including entertainment, clothing and household goods, before reducing spending on pet care. While these factors have mitigated the impacts of the challenging economic environment, the impact of difficult macroeconomic conditions increases over time.

Competition

The animal health industry is competitive. Although our business is the largest by revenues in the animal health medicines and vaccines industry, we face competition in the regions and sectors in which we compete. Principal methods of competition vary depending on the particular region, species, product category or individual product. Some of these methods include new product development, quality, price, service and promotion to veterinary professionals, pet owners and livestock producers. Our competitors include the animal health businesses of large pharmaceutical companies and specialty animal health businesses. In addition to competition from established market participants, there could be new entrants to the animal health medicines and vaccines industry in the future. In certain markets, we also compete with companies that produce generic products, but the level of competition from generic products varies from market to market. For example, the level of generic competition is higher in Europe and certain emerging markets than in the U.S.

Weather conditions and the availability of natural resources

The animal health industry and demand for many of our animal health products in a particular region are affected by weather conditions, as usage of our products follows varying weather patterns and weather-related pressures from pests, such as ticks. As a result, we may experience regional and seasonal fluctuations in our results of operations.

In addition, livestock producers depend on the availability of natural resources, including large supplies of fresh water. Their animals’ health and their ability to operate could be adversely affected if they experience a shortage of fresh water due to human population growth or floods, droughts or other weather conditions. In the event of adverse weather conditions or a shortage of fresh water, livestock producers may purchase less of our products.

For example, the drought currently impacting parts of the U.S. is considered the worst in many years, impacting both the supply of corn and the availability of grazing pasture. The decrease in harvested corn has resulted in higher corn prices, which has impacted the profitability of livestock producers of cattle, pork and poultry. Higher corn prices may contribute to reductions in herd or flock size that result in reduced spending on animal health products. Reduced availability of grazing pasture may also force cattle producers to cull their herds. Fewer heads of cattle results in reduced demand for our products. A prolonged drought could have a material adverse effect on our operating results and financial condition. The drought has affected our performance in the U.S. cattle market in the first quarter of 2013 and may continue to affect our performance during the remainder of 2013. Factors influencing the magnitude and timing of effects of a drought on our performance include, but may not be limited to, weather patterns and herd management 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. For example, in 2012, we successfully launched a vaccine for horses against the deadly Hendra virus in Australia.

28 |

In 2013, there have been several reported cases of the H7N9 avian influenza virus in China. In late March 2013, the Chinese government reported the first case of the H7N9 avian influenza virus. Since that time, over 100 cases have been detected. We are closely monitoring the developments as this situation unfolds and currently believe the impact on our 2013 global revenue will not be significant. While China continues to represent a growth opportunity for us, sales in this country represented less than 2% of our total revenue in 2012 and the majority were generated by our swine business.

Foreign exchange rates

Significant portions of our revenues and costs are exposed to changes in foreign exchange rates. Our products are sold in more than 120 countries and, as a result, our revenues are influenced by changes in foreign exchange rates. For the three months endedMarch 31, 2013, approximately 54% of our revenues were denominated in foreign currencies. Prior to the IPO, as a business unit of Pfizer and under Pfizer's global cash management system, our foreign exchange risk was managed through Pfizer. Following the Separation, we seek to manage our foreign exchange risk, in part, through operational means, including managing same-currency revenues in relation to same-currency costs and same-currency assets in relation to same-currency liabilities. As we operate in multiple foreign currencies, including the euro, the Brazilian real, the Australian dollar and other currencies, changes in those currencies relative to the U.S. dollar will impact our revenues 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, 2013, approximately 46% of our total revenues were in U.S. dollars, and our year-over-year revenue growth was unfavorably impacted by 1% from changes in foreign currency values relative to the U.S. dollar.

On February 13, 2013, the Venezuelan government devalued its currency from a rate of 4.3 to 6.3 Venezuelan bolivars per U.S. dollar. We incurred a foreign currency loss of $9 million immediately on the devaluation as a result of remeasuring the local assets and liabilities, which is included in Other (income)/deductions—net for the three months ended March 31, 2013. We will experience ongoing adverse impacts to earnings as our revenues, costs and expenses will be translated into U.S. dollars at lower rates. These impacts are not expected to be significant to our financial condition or results of operations.

Comparability of historical results and our relationship with Pfizer

During the periods covered by the combined financial statements prior to our IPO, we operated solely as a business unit of Pfizer. The combined financial statements have been derived from the consolidated financial statements and accounting records of Pfizer and include allocations for direct costs and indirect costs attributable to the operations of the animal health business of Pfizer. The combined financial statements do not purport to reflect what the results of operations, comprehensive income/(loss), financial position, equity or cash flows would have been had we operated as a standalone public company during these periods. In addition, the historical combined financial statements may not be reflective of what our results of operations, comprehensive income/(loss), financial position, equity or cash flows might be in the future as a standalone public company.

For a detailed description of the basis of presentation and an understanding of the limitations of the predictive value of the historical combined financial statements, see Notes to Condensed Consolidated and Combined Financial Statements—Note 3. Basis of Presentation.

The historical balance sheets may not be comparable to the balance sheet of the standalone company, which reflects the transfer by Pfizer of substantially all of its animal health business to us. Non-comparable elements include, for example, the allocation of Pfizer debt which was not transferred, cash and cash equivalents which were transferred at a predetermined amount, and other assets and liabilities which were not transferred due to legal restrictions and other decisions taken by Pfizer.

Our historical expenses are not necessarily indicative of the expenses we may incur in the future as a standalone public company. With respect to support functions, for example, our historical combined financial statements include expense allocations for certain support functions that are provided on a centralized basis within Pfizer, such as expenses for business technology, facilities, legal, finance, human resources, and, to a lesser extent, business development, public affairs and procurement, among others. As part of the Separation, pursuant to agreements with Pfizer, Pfizer provides us with some of the services related to these functions on a transitional basis in exchange for agreed-upon fees, and we are incurring other costs to replace the services and resources that will not be provided by Pfizer. As a standalone public company, our total costs related to such support functions may differ from the costs that were historically allocated to us from Pfizer.

We also expect to incur certain nonrecurring costs related largely to becoming a standalone public company, including new branding (which includes changes to the manufacturing process for required new packaging), the creation of a standalone infrastructure, site separation and certain legal registration and patent assignment costs. In addition, we will also incur certain costs related to the completion of FDAH integration activities. We expect these costs to range between approximately $170 million to $200 million in 2013 and an additional $70 million to $100 million in 2014. We also expect to incur internal costs to implement certain new systems, including infrastructure and an enterprise resource planning system, while our legacy systems are being fully supported by Pfizer under the transitional services agreement. We estimate these costs to range between approximately $30 million to $40 million in both 2013 and 2014.

These estimates exclude the impact of any depreciation or amortization of capitalized separation expenditures. In addition, many of our employees currently participate in certain Pfizer equity award plans. Upon any Distribution, assuming that Pfizer no longer owns a controlling interest in the company, certain Pfizer awards will accelerate vesting under their terms, and the Company may further incur additional compensation expense replacing forfeited awards to Zoetis employees. If a Distribution were to occur in 2013, we estimate these expenses could approximate $28 million ($17 million net of tax), depending upon the timing of the Distribution and the fair value of the unvested Pfizer awards at the time of Distribution.

29 |

Public company expenses

As a result of the IPO, we became subject to the reporting requirements of the Exchange Act and the Sarbanes-Oxley Act. We have established additional procedures and practices as a standalone public company. As a result, we are incurring additional costs, including internal audit, investor relations, stock administration and regulatory compliance costs.

Recent significant acquisitions and government-mandated divestitures

The assets, liabilities, operating results and cash flows of acquired businesses are included in our results commencing from their respective acquisition dates.

Delays in establishing new operating subsidiaries

Due to local regulatory and operational requirements in certain non-U.S. jurisdictions, the transfer to us of certain assets and liabilities of Pfizer's animal health business has not yet legally occurred. These assets and liabilities are not material to our combined financial statements, individually or in the aggregate.

Agreements with Pfizer

On February 6, 2013, we entered into a transitional services agreement with Pfizer whereby Pfizer agreed to provide us with various corporate support services. This agreement has a service commencement date of January 1, 2013 in the United States and December 1, 2012 for our international locations. In addition, we also entered into a master manufacturing and supply agreement with Pfizer on October 1, 2012, whereby we and Pfizer agreed to manufacture and supply products to each other commencing January 1, 2013. See Notes to Condensed Consolidated and Combined Financial Statements— Note 17B. Related Party Transactions: Agreements with Pfizer for more information related to these and other agreements, including the related costs.

Certain amounts and percentages may reflect rounding adjustments.

^(a)  Allocation of Restructuring charges and certain acquisition-related costs was $18 million in the first quarter of 2012.

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

The costs associated with our cost reduction/productivity initiatives are predominantly termination costs associated with plant closings initiated by Pfizer's manufacturing division, as well as termination costs associated with reorganization of our commercial operations in Europe. These cost reduction/productivity initiatives are ongoing.

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

Three months ended March 31, 2013 vs. three months ended April 1, 2012

Restructuring charges and certain acquisition-related costs decreased $18 million, or 72%, primarily as a result of the nonrecurrence of allocated charges from Pfizer.

Three months ended March 31, 2013 vs. three months ended April 1, 2012

U.S. operating segment

U.S. segment revenues increased by $29 million, or 7%, in the first quarter of 2013 compared to the first quarter of 2012, of which approximately $5 million resulted from growth in livestock products and approximately $24 million resulted from growth in companion animal products.

• Livestock revenue growth was due to higher sales of swine and poultry products, partially offset by a decline in cattle sales. Livestock sales were driven by the successful execution of a new portfolio pricing structure implemented late in 2012, price increases in the first quarter of 2013, increased sales of swine vaccines, and growth in medicated feed additives across cattle, poultry and swine. Lower cattle sales were driven by herd reductions due to the impact of the U.S. drought conditions.

• Companion animal revenue growth was driven by a competitor supply issue that has now been resolved, improving market dynamics, price increases and new promotional campaigns.

U.S. segment earnings increased by $17 million, or 8%, in the first quarter of 2013 compared to the first quarter of 2012, in line with revenue growth. Additionally, earnings growth was driven by higher gross margins due to favorable mix from companion animal sales.

EuAfME operating segment

EuAfME segment revenues increased by $15 million, or 5%, in the first quarter of 2013 compared to the first quarter of 2012. Operational revenue growth was $12 million, or 4%, of which approximately $6 million resulted from growth in livestock products and approximately $6 million resulted from growth in companion animal products.

• Livestock revenue growth was driven primarily by growth in the swine and poultry portfolios. The launch of a new swine vaccine that prevents porcine circovirus type 2 across many markets in the region also contributed to this growth. Additionally, the poultry product portfolio had strong sales growth in the European Union. Results were partially offset by continued adverse macroeconomic conditions throughout Western Europe.

• Companion animal revenue growth was favorably impacted by the timing of price increases in certain countries which took place earlier in 2013 than in 2012. Results were partially offset by continued adverse macroeconomic conditions throughout Western Europe. We continue to see challenging economic conditions, particularly in Southern Europe. We expect that unseasonably cold weather across much of Europe will likely delay the start of the parasiticide season, which normally begins early in the second quarter.

Additionally, segment revenues were favorably impacted by foreign exchange, which increased revenues by approximately $3 million, or 1%.

EuAfME segment earnings increased by $13 million, or 13%, in the first quarter of 2013 compared to the first quarter of 2012. The primary drivers of the increase were revenue growth, higher gross margins and operating expense management. Segment earnings were unfavorably impacted by foreign exchange of approximately 3% in the first quarter of 2013.

CLAR operating segment

CLAR segment revenues decreased by $2 million, or 1%, in the first quarter of 2013 compared to the first quarter of 2012. Operational revenue growth was $7 million, or 4%, of which approximately $8 million resulted from growth in livestock products, offset by a $1 million decline in companion animal products sales. Results in the region are largely driven by performance in its two largest markets, Brazil and Canada.

• Livestock revenue was favorably impacted by growth in swine and poultry products in Brazil. Cattle revenues in Canada also benefited from a strong fall calf season. Additionally, swine vaccines benefited from continued demand in South America across several product lines, including Improvac/Improvest, a product that reduces boar taint without the need for surgical castration.

• Companion animal revenue declines were primarily due to a competitor supply issue in Canada that benefited the first quarter of 2012 as well as an early flea and tick season caused by unusually warm weather in the prior year. These declines were partially offset by strong companion animal demand in Brazil and the launch of Trocoxil, a canine pain medication, in the region in late 2012.

Additionally, segment revenues were unfavorably impacted by foreign exchange, which decreased revenues by approximately $9 million, or 5%.

CLAR segment earnings decreased by $2 million, or 4%, in the first quarter of 2013 compared to the first quarter of 2012. Operational earnings growth was $5 million, or 9%, in the first quarter of 2013 compared to the first quarter of 2012. The increase was driven by revenue growth while operating expenses decreased. This performance was offset by the impact of the Venezuela currency devaluation, which unfavorably impacted earnings by $9 million.

APAC operating segment

APAC segment revenues increased by $1 million, or 1%, in the first quarter of 2013 compared to the first quarter of 2012. Operational revenue growth was $4 million, or 2%, of which approximately $3 million resulted from growth in livestock products and approximately $1 million resulted from growth in companion animal products.

• Livestock revenue growth was driven by higher sales of swine products, particularly in our porcine circovirus type 2 vaccine, which was launched in several new markets in Southeast Asia and Taiwan. Growth in the poultry portfolio also positively contributed to the livestock performance. Australia, our largest market in the region, New Zealand and the Southeast Asia region all contributed positive

35 |

growth. The increase in revenues was partially offset by a decline in Japan livestock sales due to the challenging economic conditions in this market.

• Companion animal revenue growth was modest, with the majority of the growth coming as a result of targeted marketing campaigns and sales force efforts.

Additionally, segment revenues were unfavorably impacted by foreign exchange, which decreased revenues by approximately $3 million, or 1%.

APAC segment operating earnings increased by $4 million, or 6%, in the first quarter of 2013 compared to the first quarter of 2012. This reflects gross margin favorability driven by favorable product mix, partially offset by higher operating expenses due to increased promotional efforts.

Other business activities

Reflects the R&D activity managed by our centralized Research and Development Organization. Our centralized spending on R&D increased by $9 million, or 14%, in the first quarter of 2013 compared to the first quarter of 2012, primarily due to $11 million in comparable R&D expense for the first quarter of 2012 included in the Corporate segment related to operations now managed by the Research and Development Organization.

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. We report adjusted net income to portray the results of our major operations, the discovery, development, manufacture and commercialization of animal health medicine and vaccine products, prior to considering certain income statement elements. We have defined adjusted net income as net income attributable to Zoetis before the impact of purchase accounting adjustments, acquisition-related costs and certain significant items. The adjusted net income measure is not, and should not be viewed as, a substitute for U.S. GAAP reported net income attributable to Zoetis.

The adjusted net income measure is an important internal measurement for us. We measure our overall performance on this basis in conjunction with other performance metrics. The following are examples of how the adjusted net income measure is utilized:

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

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

• other goal setting and performance measurements.

Despite the importance of this measure to management in goal setting and performance measurement, adjusted net income is a non-GAAP financial measure that has no standardized meaning prescribed by U.S. GAAP and, therefore, has limits in its usefulness to investors. Because of its non-standardized definition, adjusted net income, unlike U.S. GAAP net income, may not be comparable to the calculation of similar measures of other companies. Adjusted net income is presented to permit investors to more fully understand how management assesses performance.

We also recognize that, as an internal measure of performance, the adjusted net income measure has limitations, and we do not restrict our performance management process solely to this metric. A limitation of the adjusted net income measure is that it provides 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 does not provide a comparable view of our performance to other companies. We also use other specifically tailored tools designed to achieve the highest levels of performance.  

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 Pharmacia Animal Health business (acquired in 2003), Fort Dodge Animal Health (FDAH) (acquired in 2009) and King Animal Health (KAH) (acquired in 2011), include the incremental charge to cost of sales from the sale of acquired inventory that was written up to fair value, 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 revenues 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

36 |

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 revenues, 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, integration, restructuring and additional depreciation 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 restructure 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 and restructuring costs associated with a business combination may occur over several years, with the more significant impacts 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 Food and Drug Administration 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 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; costs related to becoming a standalone public company; adjustments related to the resolution of certain tax positions; the impact of adopting certain significant, event-driven tax legislation; or charges related to legal matters. See Notes to Condensed Consolidated and Combined 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.

Analysis of the condensed consolidated and combined statements of comprehensive income

Virtually 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 and combined balance sheets

March 31, 2013 vs. December 31, 2012

For a discussion about the changes in Cash and cash equivalents, Short-term borrowing, including current portion of allocated long term debt, and Long-term debt, see “Analysis of financial condition, liquidity and capital resources” below.

Accounts receivable, less allowance for doubtful accounts decreased as a result of Separation Adjustments, partially offset by operational increases due to higher net sales. See Notes to Condensed Consolidated and Combined Financial Statements— Note 2B. The Separation, Adjustments Associated with the Separation, Senior Notes Offering and Initial Public Offering: Adjustments Associated with the Separation.

Receivable from Pfizer Inc. and Payable to Pfizer Inc. are the result of related party transactions. See Notes to Condensed Consolidated and Combined Financial Statements— Note 17. Related Party Transactions for more information related to these agreements.

Inventories decreased primarily as a result of Separation Adjustments, as well as operational reductions. See Notes to Condensed Consolidated and Combined Financial Statements— Note 2B. The Separation, Adjustments Associated with the Separation, Senior Notes Offering and Initial Public Offering: Adjustments Associated with the Separation and Note 10. Inventories.

The net changes in Current deferred tax assets, Noncurrent deferred tax assets, Noncurrent deferred tax liabilities and Other taxes payable primarily reflect Separation Adjustments. See Notes to Condensed Consolidated and Combined Financial Statements— Note 2B. The Separation, Adjustments Associated with the Separation, Senior Notes Offering and Initial Public Offering: Adjustments Associated with the Separation and Note 7. Income Taxes.

Property, plant and equipment, less accumulated depreciation was virtually unchanged as Separation Adjustments were offset by operational activity (depreciation and capital spending). See Notes to Condensed Consolidated and Combined Financial Statements— Note 2B. The Separation, Adjustments Associated with the Separation, Senior Notes Offering and Initial Public Offering: Adjustments Associated with the Separation.

Accounts payable decreased due to timing of payments.

Dividends payable relates to the dividend declared on March 28, 2013.

Accrued Compensation and related items declined primarily due to the payment of 2012 annual bonuses to eligible U.S.-based employees in the first quarter of 2013.

Long-term debt reflects the senior notes offering. See Notes to Condensed Consolidated and Combined Financial Statements— Note 2C. The Separation, Adjustments Associated with the Separation, Senior Notes Offering and Initial Public Offering: Senior Notes Offering and Note 9D. Financial Instruments: Senior Notes Offering.

Allocated long-term debt decreased as a result of Separation Adjustments. See Notes to Condensed Consolidated and Combined Financial Statements— Note 2B.

Three months ended March 31, 2013 vs. three months ended April 1, 2012

Our net cash provided by operating activities was $281 million in the first quarter of 2013 compared to cash used in operating activities of $4 million in the first quarter of 2012. This increase in operating cash flows was primarily attributable to timing of receipts and payments in the ordinary course of business and operational reductions in inventory.

For the three months ended April 1, 2012, the line item "Other changes in assets and liabilities, net of transfers with Pfizer Inc." primarily reflects the timing of production of certain products, which are produced only once a year.

Investing activities

Three months ended March 31, 2013 vs. three months ended April 1, 2012

Our net cash used in investing activities was $22 million in the first quarter of 2013 compared to cash used in investing activities of $33 million in the first quarter of 2012. The decrease in investing cash flows used was primarily attributable to lower expenditures for property, plant and equipment.

Financing activities

Three months ended March 31, 2013 vs. three months ended April 1, 2012

Our net cash used in financing activities was $108 million in the first quarter 2012 compared to cash provided by financing activities of $71 million in the first quarter of 2012. The decrease in net cash provided by financing activities was attributable to the net transfers from Pfizer as a result of the Separation.

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.

Over the last five years, the global financial markets have undergone and may continue to experience significant volatility and disruption. The timing and sustainability of an economic recovery is uncertain and additional macroeconomic, business and financial disruptions may arise. As markets change, we will continue to monitor our liquidity position, and there can be no assurance that the challenging economic environment or a further economic downturn would 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)	2013		2012
Cash and cash equivalents(a)	$	468	$	317
Accounts receivable, net(b)	861		900
Short-term borrowings, including current portion of allocated long-term debt in 2012(c)	6		73
Allocated long-term debt(c)	—		509
Long-term debt(d)	3,640		—
Working capital	1,655		1,741
Ratio of current assets to current liabilities	2.29:1		2.55:1

^(a)  Prior to our IPO, we participated in Pfizer's centralized cash management system, and generally all of our excess cash was transferred to Pfizer on a daily basis. Cash disbursements for operations and/or investing activities were funded, as needed, by Pfizer.

^(b)  Accounts receivable are usually collected over a period of 60 to 90 days. For the three months ended March 31, 2013 compared to December 31, 2012, the number of days that accounts receivables are outstanding decreased slightly. 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 history, historical and expected collection patterns, the financial condition of our customers, the robust nature of our credit and collection practices and the economic environment.

^(c)  The combined financial statements for December 31, 2012 include an allocation of long-term debt from Pfizer that was issued to partially finance the acquisition of Wyeth (including FDAH). The debt has been allocated on a pro-rata basis using the deemed acquisition cost of FDAH as a percentage of the total acquisition cost of Wyeth. After the IPO, Pfizer retained the allocated debt.

^(d)  Consists of $3.65 billion aggregate principal amount of our senior notes, with an original issue discount of $10 million. The senior notes are comprised of $400 million aggregate principal amount of our 1.150% senior notes due 2016, $750 million aggregate principal amount of our 1.875% senior notes due 2018, $1.35 billion aggregate principal amount of our 3.250% Senior Notes due 2023 and $1.15 billion aggregate principal amount of our 4.700% senior notes due 2043.

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

Credit facility and other lines of credit

In December 2012, we entered into a revolving credit agreement with a syndicate of banks providing for a five-year $1.0 billion senior unsecured revolving credit facility, which became effective in February 2013 upon the completion of the IPO and expires in December 2017. 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 4.35:1 for fiscal year 2013, 3.95:1 for fiscal year 2014, 3.50:1 for fiscal year 2015 and 3.00:1 thereafter. 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. Subject to certain conditions, we have the right to increase the credit facility to up to $1.5 billion. There are currently no borrowings outstanding.

We have additional lines of credit with a group of banks and other financial intermediaries. We maintain cash and cash equivalent balances in excess of our outstanding short-term borrowings. As of March 31, 2013, we had access to $52 million of lines of credit and had $6 million of borrowings outstanding.

Domestic and international short-term funds

Many of our operations are conducted outside the U.S. As part of the Separation, we received significant portions of cash and cash equivalents held internationally. Approximately 60% of cash and cash equivalents transferred was held outside the U.S. Going forward, the amount of funds

42 |

held in U.S. tax jurisdictions 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 domestic and international cash flows (both inflows and outflows). Repatriation of overseas funds can result in additional U.S. federal, state and local income tax payments. We record U.S. deferred tax liabilities for certain unremitted earnings, but when amounts earned overseas are expected to be indefinitely reinvested outside the U.S., no accrual for U.S. taxes 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 January 28, 2013, we issued $3.65 billion aggregate principal amount of our senior notes (the senior notes offering) in a private placement, with an original issue discount of $10 million. The senior notes are comprised of $400 million aggregate principal amount of our 1.150% senior notes due 2016, $750 million aggregate principal amount of our 1.875% senior notes due 2018, $1.35 billion aggregate principal amount of our 3.250% senior notes due 2023 and $1.15 billion aggregate principal amount of our 4.700% senior notes due 2043.

We sold $2.65 billion aggregate principal amount of our senior notes through the initial purchasers in the senior notes offering and Pfizer transferred $1.0 billion aggregate principal amount of our senior notes to certain of the initial purchasers, who sold such senior notes through the initial purchasers in the senior notes offering. We paid an amount of cash equal to substantially all of the net proceeds that we received in the senior notes offering to Pfizer prior to the completion of the IPO.

The 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 senior notes may be declared immediately due and payable.

Pursuant to the indenture, we are able to redeem the 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 2023 notes 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 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 purchase each of the senior notes at a price equal to 101% of the aggregate principal amount of the senior notes together with accrued and unpaid interest to, but excluding, the date of repurchase.

The components of our long-term debt follow:

Description	Principal Amount	Interest Rate	Terms
2016 Senior Note	$400 million	1.150%	Interest due semi annually, not subject to amortization, aggregate principal due on February 1, 2016
2018 Senior Note	$750 million	1.875%	Interest due semi annually, not subject to amortization, aggregate principal due on February 1, 2018
2023 Senior Note	$1,350 million	3.250%	Interest due semi annually, not subject to amortization, aggregate principal due on February 1, 2023
2043 Senior Note	$1,150 million	4.700%	Interest due semi annually, not subject to amortization, aggregate principal due on February 1, 2043

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	Baa2	Stable	January 2013
S&P	A-3	BBB-	Stable	January 2013

Pension Obligations

As part of the Separation, Pfizer transferred to us, the net pension obligation of $25 million associated with certain international defined benefit plans. Estimated net pension obligations of approximately $23 million, associated with additional defined benefit pension plans in certain international locations, are expected to be transferred to us, later in 2013, in accordance with the applicable local separation agreements. We

43 |

expect to contribute approximately $7 million to the plans in 2013. For additional information, see Notes to Condensed Consolidated and Combined Financial Statements—Note 12. Benefit Plans.

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 generally are 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, 2013 or December 31, 2012, recorded amounts for the estimated fair value of these indemnifications are not significant.

New accounting standards

For discussion of our new accounting standards, see Notes to Condensed Consolidated and Combined Financial Statements—Note 4A. Significant Accounting Policies: New Accounting Standards.

Recently Issued Accounting Standards, Not Adopted as of March 31, 2013

In March 2013, the Financial Accounting Standards Board (FASB) issued an accounting standards update regarding the accounting for cumulative translation adjustment (CTA) upon derecognition of assets or investment within a foreign entity. This new standard provides additional CTA accounting guidance on sales or transfers of foreign entity investments and assets, as well as step acquisitions involving a foreign entity. The provisions of the new standard are effective January 1, 2014, but we do not expect the provisions of this standard to have a significant impact on our consolidated financial statements.

In February 2013, the FASB issued an accounting standards update regarding the measurement of obligations resulting from joint and several liability arrangements that may include debt agreements, other contractual obligations and settled litigation or judicial rulings. The provisions of this standard require that these obligations are measured at the amount representing the agreed upon obligation of the company, as well as additional liability amounts it expects to assume on behalf of other parties in the arrangement. The provisions of the new standard are effective January 1, 2014, but we do not expect the provisions of this standard to have a significant impact on our consolidated financial statements.

Forward-looking statements and factors that may affect future results

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

In particular, forward-looking statements include statements relating to the Separation, our indebtedness, our ability to make interest and principal payments on our indebtedness, our ability to satisfy the covenants contained in our indebtedness, the redemption of the notes, new systems infrastructure stand-up, our 2013 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, interest rates, foreign exchange rates, growth in emerging markets, the outcome of contingencies, such as legal proceedings, dividend plans, the timing and structuring of the Distribution, our agreements with Pfizer, Pfizer's control of our company, 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 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;

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

• changes in tax laws and regulation;

• an outbreak of infectious disease carried by animals;

• 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;

• quarterly fluctuations in demand and costs;

• failure to achieve the expected benefits of the Separation or the Distribution, which include improved strategic and operational efficiency, the adoption of a capital structure and investment and dividend policies that are designed for our standalone company, the

44 |

use of our equity to facilitate future acquisitions and improved alignment of employee incentives with our performance and growth objectives;

• operation as a standalone public company without many of the resources previously available to us as a business unit of Pfizer;

• control of a majority of the voting power of our common stock by Pfizer and, as a result, Pfizer's ability to determine the outcome of our future corporate actions, including the election of our directors;

• actual or potential conflicts of interest as a result of the fact that several of our directors will simultaneously serve as employees of Pfizer; and

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

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. You are advised, however, to consult any further disclosures we make on related subjects in our Form 10-Q and 8-K reports and our other filings with the SEC. You should understand that it is not possible to predict or identify all such factors. Consequently, you should not consider the above to be a complete discussion of all potential risks or uncertainties.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

A significant portion of our revenues 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 euro, Brazilian real and Australian dollar. Prior to the IPO, as a business unit of Pfizer and under Pfizer's global cash management system, our foreign exchange risk was managed through Pfizer. Following the Separation, we seek to manage our foreign exchange risk, in part, through operational means, including managing same-currency revenues 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, 2013 were analyzed to determine their sensitivity to foreign exchange rate changes. The fair values of these instruments were determined using Level 2 inputs. For additional details, see Notes to Condensed Consolidated and Combined Financial Statements—Note 4B. Significant Accounting Policies: Fair Value. The sensitivity analysis of changes in the fair value of all foreign currency forward-exchange contracts at March 31, 2013 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 $30 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 $33 million. For additional details, see Notes to Condensed Consolidated and Combined Financial Statements—Note 9E. Financial Instruments: Derivative Financial Instruments.

Interest rate risk

Our outstanding debt balances are 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 revolving credit facility will be exposed to interest rate fluctuations. At March 31, 2013, we had no outstanding principal balance under our credit facility. See Notes to Condensed Consolidated and Combined Financial Statements—Note 9. Financial Instruments.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

An evaluation was carried out under the supervision and with the participation of the company's management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934). Based upon that evaluation as of March 31, 2013, our Chief Executive Officer and Chief Financial Officer each concluded that, as of the end of such period, our disclosure controls and procedures were effective in ensuring that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported on a timely basis, and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Controls over Financial Reporting

This report does not include management's assessment regarding changes in internal control over financial reporting due to a transition period established by rules of the SEC for newly public companies.
