Overview of our business
Zoetis is a global leader in the animal health industry, focused on the
discovery, development, manufacture and commercialization of medicines,
vaccines, diagnostic products, biodevices, genetic tests and precision livestock
farming technology. For nearly 70 years, we have been innovating ways to
predict, prevent, detect, and treat animal illness, and continue to stand by
those raising and caring for animals worldwide - from livestock farmers to
veterinarians and pet owners.
We manage our operations through two geographic operating segments: the United
States (U.S.) and International. Within each of these operating segments, we
offer a diversified product portfolio for both companion animal and livestock
customers in order to capitalize on local and regional trends and customer
needs. See Notes to Condensed Consolidated Financial Statements - Note 16.
Segment Information.
We directly market our products to veterinarians and livestock producers located
in approximately 45 countries across North America, Europe, Africa, Asia,
Australia and South America, and are a market leader in nearly all of the major
regions in which we operate. Through our efforts to establish an early and
direct presence in many emerging markets, such as Brazil, Chile, China and
Mexico, we believe we are one of the largest animal health medicines and
vaccines businesses as measured by revenue across emerging markets as a whole.
In markets where we do not have a direct commercial presence, we generally
contract with distributors that provide logistics and sales and marketing
support for our products.
We believe our investments in one of the industry's largest sales organizations,
including our extensive network of technical and veterinary operations
specialists, our high-quality manufacturing and reliability of supply, and our
long track record of developing products that meet customer needs, has led to
enduring and valued relationships with our customers. Our research and
development (R&D) efforts enable us to deliver innovative products to address
unmet needs and evolve our product lines so they remain relevant for our
customers.
Our products include over 300 products and product lines that we sell in over
100 countries for the prediction, prevention, detection and treatment of
diseases and conditions that affect various companion animal and livestock
species. The diversity of our product portfolio and our global operations
provides stability to our overall business. For instance, in livestock, impacts
on our revenue that may result from disease outbreaks or weather conditions in a
particular market or region are often offset by increased sales in other regions
from exports and other species as consumers shift to other proteins.
Beginning in the first quarter of 2021, certain costs associated with
information technology that specifically support our global manufacturing
operations, which were previously reported in Other unallocated, are now
reported in Corporate. In addition, in the first quarter of 2021, the company
realigned certain management responsibilities. These changes did not impact the
determination of our operating segments, however they resulted in the
reallocation of certain costs between segments. These changes primarily include
the following: (i) certain diagnostics costs, which were previously reported in
Corporate, are now reported in our U.S. results; and (ii) certain other
miscellaneous costs, which were previously reported in our U.S. results, are now
reported in Corporate.
Certain reclassifications of prior year information have been made to conform to
the current year's presentation.

Uncertainty Relating to COVID-19
We continue to closely monitor the impact of the coronavirus (COVID-19) pandemic
and the resulting global recession on all aspects of our business across
geographies, including how it has and may continue to impact our customers,
workforce, suppliers and vendors. We are currently designated an essential
business globally and have continued physical operations with respect to
research and development, manufacturing and our supply chain. As the pandemic
continues to progress, the severity of the impact across markets remains
uncertain as the number of cases rises and falls in various jurisdictions
leading to changes in the imposition of restrictive measures intended to contain
the virus and its variants.
Due to numerous uncertainties regarding the continuing COVID-19 pandemic, we are
unable to fully predict the impact that it will ultimately have on our future
financial position and operating results. These uncertainties include the
severity of the virus, the duration of the outbreak and number of recurrences,
the effectiveness of measures to contain and treat the virus, including the
timing, adoption and effectiveness of widespread vaccinations, the emergence of
virus variants and the effectiveness of vaccines against the current and any
future variants, governmental, business or other actions in response to the
pandemic (which could include actions that result in limitations on, or
disruptions to, our manufacturing, transportation and other operations, or
mandates to provide products or services), impacts on our supply chain, the
effect on customer demand, or changes to our operations. We cannot predict the
impact that the COVID-19 pandemic will have on our customers, vendors and
suppliers; however, any material effect on these parties could adversely impact
us. In particular, our livestock customers have been, and may continue to be,
negatively impacted by facility closures, reduced packing plant capacity,
quarantines, travel bans and labor shortages, and the shift in protein
production from foodservice to grocery, among other impacts. In addition, our
companion animal customers have been, and may in the future be, negatively
impacted by lack of demand for veterinary services in areas where lockdown and
stay-at-home orders are in place. The impact of COVID-19 on our customers could
reduce the demand for our products, which could adversely impact our revenue.
The health of our workforce, and our ability to meet staffing needs in our
manufacturing operations and other critical functions, cannot be predicted and
are vital to our operations. Further, the impacts of a prolonged global
recession and potential disruptions to, and volatility in, the credit and
financial markets, as well as other unanticipated consequences, remain unknown.
The situation surrounding COVID-19 remains fluid, and we will continue to
actively monitor the situation and may take actions that alter our business
operations that we determine are in the best interests of our workforce,
customers, vendors, suppliers, and other stakeholders, or as required by
federal, state, or local authorities. It is not clear what the potential effects
any such alterations or modifications may ultimately have on our business,
including the effects on our customers, workforce, and prospects, or on our
financial results for the remainder of fiscal 2021.
For further information regarding the impact of COVID-19 on the Company, see
Item 1A, Risk Factors in this Quarterly Report on Form 10-Q.
Quarterly Variability of Financial Results
Our quarterly financial results are subject to variability related to a number
of factors including but not limited to: the impact of the COVID-19 pandemic
discussed above, weather patterns, herd management decisions, economic
conditions, regulatory actions, competitive dynamics, disease outbreaks, product
and geographic mix, timing of price increases and timing of investment
decisions.
Disease Outbreaks
Sales of our livestock products have in the past, and may in the future be,
adversely affected by the outbreak of disease carried by animals. Outbreaks of
disease may reduce regional or global sales of particular animal-derived food
products or result in reduced exports of such products, either due to heightened
export restrictions or import prohibitions, which may reduce demand for our
products. Also, the outbreak of any highly contagious disease near our main
production sites could require us to immediately halt production of our products
at such sites or force us to incur substantial expenses in procuring raw
materials or products elsewhere. Alternatively, sales of products that treat
specific disease outbreaks may increase.
Foreign Exchange Rates
Significant portions of our revenue and costs are exposed to changes in foreign
exchange rates. Our products are sold in more than 100 countries and, as a
result, our revenue is influenced by changes in foreign exchange rates. For the
six months ended June 30, 2021, approximately 45% of our revenue was denominated
in foreign currencies. We seek to manage our foreign exchange risk, in part,
through operational means, including managing same-currency revenue in relation
to same-currency costs and same-currency assets in relation to same-currency
liabilities. As we operate in multiple foreign currencies, including the euro,
Chinese yuan, Brazilian real, Australian dollar, Canadian dollar, British pound
and other currencies, changes in those currencies relative to the U.S. dollar
will impact our revenue, cost of goods and expenses, and consequently, net
income. Exchange rate fluctuations may also have an impact beyond our reported
financial results and directly impact operations. These fluctuations may affect
the ability to buy and sell our goods and services between markets impacted by
significant exchange rate variances. For the six months ended June 30, 2021,
approximately 55% of our total revenue was in U.S. dollars. Our year-over-year
total revenue growth was favorably impacted by approximately 2% from changes in
foreign currency values relative to the U.S. dollar.
Non-GAAP financial measures
We report information in accordance with U.S. generally accepted accounting
principles (GAAP). Management also measures performance using non-GAAP financial
measures that may exclude certain amounts from the most directly comparable GAAP
financial measure. Despite the importance of these measures to management in
goal setting and performance measurement, non-GAAP financial measures have no
standardized meaning prescribed by U.S. GAAP and, therefore, have limits in
their usefulness to investors and may not be comparable to the calculation of
similar measures of other companies. We present certain identified non-GAAP
measures solely to provide investors with useful information to more fully
understand how management assesses performance.
Operational Growth
We believe that it is important to not only understand overall revenue and
earnings growth, but also "operational growth." Operational growth is a non-GAAP
financial measure defined as revenue or earnings growth excluding the impact of
foreign exchange. This measure provides information on the change in revenue and
earnings as if foreign currency exchange rates had not changed between the
current and prior periods to facilitate a period-to-period comparison. We
believe this non-GAAP measure provides a useful comparison to previous periods
for the company and investors, but should not be viewed as a substitute for U.S.
GAAP reported growth.

                                                                            24 |

  Table of Contents
Adjusted Net Income and Adjusted Earnings Per Share
Adjusted net income and the corresponding adjusted earnings per share (EPS) are
non-GAAP financial measures of performance used by management. We believe these
financial measures are useful supplemental information to investors when
considered together with our U.S. GAAP financial measures. We report adjusted
net income to portray the results of our major operations, and the discovery,
development, manufacture and commercialization of our products, prior to
considering certain income statement elements. We define adjusted net income and
adjusted EPS as net income attributable to Zoetis and EPS before the impact of
purchase accounting adjustments, acquisition-related costs and certain
significant items.
We recognize that, as an internal measure of performance, the adjusted net
income and adjusted EPS measures have limitations, and we do not restrict our
performance management process solely to these metrics. A limitation of the
adjusted net income and adjusted EPS measures is that they provide a view of our
operations without including all events during a period, such as the effects of
an acquisition or amortization of purchased intangibles, and do not provide a
comparable view of our performance to other companies. The adjusted net income
and adjusted EPS measures are not, and should not be viewed as, a substitute for
U.S. GAAP reported net income and reported EPS. See the Adjusted Net Income
section below for more information.

employees, assets and activities that will not continue in the future, as well
as integration costs. Net restructuring charges are primarily related to asset
impairment charges, employee termination costs and exit costs. Our integration
costs are generally comprised of consulting costs related to the integration of
systems and processes, as well as product transfer costs.

*Calculation not meaningful
Three months ended June 30, 2021 vs. three months ended June 30, 2020
The change in Other (income)/deductions-net is primarily as a result of a net
loss related to the sale of certain assets of our poultry automation business
located in the U.S. and Canada in the current period, as well as higher foreign
currency losses and lower royalty income as compared to the prior year period,
partially offset by intangible asset impairment charges and an impairment of an
equity investment incurred in the prior year period.
Six months ended June 30, 2021 vs. six months ended June 30, 2020
The change in Other (income)/deductions-net is primarily as a result of a net

effective tax rate for the three months ended June 30, 2021, was primarily
attributable to:
•changes in the jurisdictional mix of earnings, which includes the impact of the
location of earnings from operations and repatriation costs. The jurisdictional
mix of earnings can vary as a result of repatriation decisions, operating
fluctuations in the normal course of business and the impact of non-deductible

Three months ended June 30, 2021 vs. three months ended June 30, 2020
U.S. operating segment
U.S. segment revenue increased by $181 million, or 22%, in the three months
ended June 30, 2021, compared with the three months ended June 30, 2020,
reflecting an increase of approximately $200 million in companion animal
products, partially offset by a decrease of approximately $19 million in
livestock products. The growth is inclusive of the market recovery from COVID-19
impacts in the same quarter of the prior year.
•Companion animal revenue growth was driven primarily by increased sales of
parasiticides, including Simparica Trio®, our new triple combination
parasiticide, as well as the ProHeart® and Revolution®/Stronghold® franchises.
In-line products growth benefited from increased sales of our key dermatology
portfolio, as well as our vaccine and diagnostic products.
•Livestock revenue declined primarily due to decreased sales in cattle and
poultry, while swine was essentially flat for the quarter. Cattle product sales
declined as a result of a promotion that ran in the first quarter of this year,
increased generic competition and challenges in the beef and dairy end-markets
due to rising input costs. The poultry portfolio declined as a result of the
expanded use of lower cost alternatives to Zoetis' premium products, smaller
flock sizes reducing disease pressure, as well as generic competition for
Zoamix® and BMD®, the company's alternatives to antibiotics in medicated feed
additives.
U.S. segment earnings increased by $111 million, or 21%, in the three months
ended June 30, 2021, compared with the three months ended June 30, 2020,
primarily due to revenue and gross margin growth.
International operating segment
International segment revenue increased by $216 million, or 31%, in the three
months ended June 30, 2021, compared with the three months ended June 30, 2020.
Operational revenue increased by $157 million, or 22%, driven by growth of
approximately $116 million in companion animal products and $41 million in
livestock products. The growth is inclusive of the market recovery from COVID-19
impacts in the same period of the prior year.
•Companion animal operational revenue growth was driven primarily by increased
sales of our parasiticide products, including the Simparica® and
Revolution/Stronghold franchises. Growth also resulted from sales across the
broader in-line portfolio, including our key dermatology portfolio, which
benefited from increased pet ownership and standards of care.

                                                                            30 |
--------------------------------------------------------------------------------

•Livestock operational revenue growth was driven by increased sales in cattle,
swine and fish. Cattle product sales increased due to marketing campaigns,
favorable export market conditions in Brazil and favorable conditions in other
emerging markets. Swine product sales increased as a result of the continued
expansion of production in key accounts in China. Growth in the fish portfolio
resulted primarily from increased sales of the Alpha Flux® sea lice treatment
product and the recent acquisition of Fish Vet Group.
•Additionally, International segment revenue was favorably impacted by foreign
exchange which increased revenue by approximately $59 million, or 9%, primarily
driven by the euro, Australian dollar, Chinese yuan, Canadian dollar and British
pound, partially offset by the Argentinian peso and Brazilian real.
International segment earnings increased by $137 million, or 38%, in the three
months ended June 30, 2021, compared with the three months ended June 30, 2020.
Operational earnings growth was $101 million, or 28%, primarily due to revenue
and gross margin growth.
Six months ended June 30, 2021 vs. six months ended June 30, 2020
U.S. operating segment
U.S. segment revenue increased by $328 million, or 20%, in the six months ended
June 30, 2021, compared with the six months ended June 30, 2020, reflecting an
increase of approximately $359 million in companion animal products, partially
offset by a decrease of approximately $31 million in livestock products. The
growth is inclusive of the market recovery from COVID-19 impacts in the same
period of the prior year.
•Companion animal revenue growth was driven primarily by increased sales of

parasiticide, as well as the ProHeart and Revolution/Stronghold franchises.
In-line product growth benefited from increased sales of our key dermatology
portfolio, diagnostics products and vaccines.
•Livestock revenue declined due to poultry, swine and cattle. The poultry
portfolio declined as a result of the expanded use of lower cost alternatives to
Zoetis' premium products, smaller flock sizes reducing disease pressure, as well
as generic competition for Zoamix and BMD, the company's alternatives to
antibiotics in medicated feed additives. The decline in swine product sales was
primarily due to a non-recurring government purchase in the prior year. Cattle
product sales declined as a result of increased generic competition.
U.S. segment earnings increased by $235 million, or 23%, in the six months ended
June 30, 2021, compared with the six months ended June 30, 2020, primarily due
to revenue and gross margin growth.
International operating segment
International segment revenue increased by $410 million, or 29%, in the six
months ended June 30, 2021, compared with the six months ended June 30, 2020.
Operational revenue increased by $340 million, or 24%, driven by growth of
approximately $227 million in companion animal products and $113 million in
livestock products. The growth is inclusive of the market recovery from COVID-19
impacts in the same period of the prior year.
•Companion animal operational revenue growth was driven primarily by increased
sales of our parasiticide products, including the Simparica and
Revolution/Stronghold franchises. Also contributing to growth were our vaccine
products, key dermatology portfolio, and diagnostic products. Growth across the
broader in-line portfolio benefited from increased pet ownership and standards
of care.
•Livestock operational revenue growth was primarily driven by increased sales in
cattle, swine and fish. Growth in cattle product sales was mainly due to the
effect of marketing campaigns, key account penetration and favorable export
market conditions in Brazil and other emerging markets. Sales of swine products
grew as a result of expanding production in the wake of African Swine Fever in
China. Fish growth was due to an increase in vaccine sales in key salmon markets
and the recent acquisition of Fish Vet Group.
•Additionally, International segment revenue was favorably impacted by foreign
exchange which increased revenue by approximately $70 million, or 5%, primarily
driven by the euro, Chinese yuan and Australian dollar, partially offset by the
Brazilian real.
International segment earnings increased by $268 million, or 36%, in the six
months ended June 30, 2021, compared with the six months ended June 30, 2020.
Operational earnings growth was $223 million, or 30%, primarily due to revenue
and gross margin growth.
Other business activities
Other business activities includes our Client Supply Services (CSS) contract
manufacturing results, our human health business and expenses associated with
our dedicated veterinary medicine research and development organization,
research alliances, U.S. regulatory affairs and other operations focused on the
development of our products. Other R&D-related costs associated with non-U.S.
market and regulatory activities are generally included in the International
segment.
Three months ended June 30, 2021 vs. three months ended June 30, 2020
Other business activities net loss increased by $8 million in the three months
ended June 30, 2021, compared with the three months ended June 30, 2020,
reflecting an increase in R&D costs due to an increase in compensation-related
costs, an increase in project investments and unfavorable foreign exchange.
Six months ended June 30, 2021 vs. six months ended June 30, 2020
Other business activities net loss increased by $18 million in the six months
ended June 30, 2021, compared with the six months ended June 30, 2020,
reflecting an increase in R&D costs due to an increase in compensation-related
costs, an increase in project investments and unfavorable foreign exchange,
partially offset by lower travel and entertainment expenses as a result of
decreases in travel and events related to the COVID-19 pandemic.

Adjusted net income
General description of adjusted net income (a non-GAAP financial measure)
Adjusted net income is an alternative view of performance used by management,
and we believe that investors' understanding of our performance is enhanced by
disclosing this performance measure. The adjusted net income measure is an
important internal measurement for us. Additionally, we measure our overall
performance on this basis in conjunction with other performance metrics. The
following are examples of how the adjusted net income measure is utilized:
•senior management receives a monthly analysis of our operating results that is
prepared on an adjusted net income basis;
•our annual budgets are prepared on an adjusted net income basis; and
•other goal setting and performance measurements.
Purchase accounting adjustments
Adjusted net income is calculated prior to considering certain significant
purchase accounting impacts that result from business combinations and net asset
acquisitions. These impacts, primarily associated with the acquisition of Abaxis
(acquired in July 2018), the Pharmaq business (acquired in November 2015),
certain assets of Abbott Animal Health (acquired in February 2015), King Animal
Health (KAH) (acquired in 2011), Fort Dodge Animal Health (FDAH) (acquired in
2009), and Pharmacia Animal Health business (acquired in 2003), include
amortization related to the increase in fair value of the acquired finite-lived
intangible assets and depreciation related to the increase/decrease to fair
value of the acquired fixed assets. Therefore, the adjusted net income measure
includes the revenue earned upon the sale of the acquired products without
considering the aforementioned significant charges.
While certain purchase accounting adjustments can occur through 20 or more
years, this presentation provides an alternative view of our performance that is
used by management to internally assess business performance. We believe the
elimination of amortization attributable to acquired intangible assets provides
management and investors an alternative view of our business results by
providing a degree of parity to internally developed intangible assets for which
R&D costs previously have been expensed.
A completely accurate comparison of internally developed intangible assets and
acquired intangible assets cannot be achieved through adjusted net income. These
components of adjusted net income are derived solely from the impact of the
items listed above. We have not factored in the impact of any other differences
in experience that might have occurred if we had discovered and developed those
intangible assets on our own, and this approach does not intend to be
representative of the results that would have occurred in those circumstances.
For example, our R&D costs in total, and in the periods presented, may have been
different; our speed to commercialization and resulting revenue, if any, may
have been different; or our costs to manufacture may have been different. In
addition, our marketing efforts may have been received differently by our
customers. As such, in total, there can be no assurance that our adjusted net
income amounts would have been the same as presented had we discovered and
developed the acquired intangible assets.
Acquisition-related costs
Adjusted net income is calculated prior to considering transaction and
integration costs associated with significant business combinations or net asset
acquisitions because these costs are unique to each transaction and represent
costs that were incurred to acquire and integrate certain businesses as a result
of the acquisition decision. We have made no adjustments for the resulting
synergies.
We believe that viewing income prior to considering these charges provides
investors with a useful additional perspective because the significant costs
incurred in a business combination result primarily from the need to eliminate
duplicate assets, activities or employees--a natural result of acquiring a fully
integrated set of activities. For this reason, we believe that the costs
incurred to convert disparate systems, to close duplicative

                                                                            32 |
--------------------------------------------------------------------------------

facilities or to eliminate duplicate positions (for example, in the context of a
business combination) can be viewed differently from those costs incurred in the
ordinary course of business.
The integration costs associated with a business combination may occur over
several years, with the more significant impacts generally ending within three
years of the transaction. Because of the need for certain external approvals for
some actions, the span of time needed to achieve certain restructuring and
integration activities can be lengthy. For example, due to the regulated nature
of the animal health medicines, vaccines and diagnostics business, the closure
of excess facilities can take several years, as all manufacturing changes are
subject to extensive validation and testing and must be approved by the U.S.
Food and Drug Administration and/or other regulatory authorities.
Certain significant items
Adjusted net income is calculated excluding certain significant items. Certain
significant items represent substantive, unusual items that are evaluated on an
individual basis. Such evaluation considers both the quantitative and the
qualitative aspect of their unusual nature. Unusual, in this context, may
represent items that are not part of our ongoing business; items that, either as
a result of their nature or size, we would not expect to occur as part of our
normal business on a regular basis; items that would be nonrecurring; or items
that relate to products that we no longer sell. While not all-inclusive,
examples of items that could be included as certain significant items would be
costs related to a major non-acquisition-related restructuring charge and
associated implementation costs for a program that is specific in nature with a
defined term, such as those related to our non-acquisition-related
cost-reduction and productivity initiatives; amounts related to disposals of
products or facilities that do not qualify as discontinued operations as defined
by U.S. GAAP; certain intangible asset impairments; adjustments related to the
resolution of certain tax positions; significant currency devaluation; the
impact of adopting certain significant, event-driven tax legislation; or charges
related to legal matters. See Notes to Condensed Consolidated Financial
Statements- Note 15. Commitments and Contingencies. Our normal, ongoing defense
costs or settlements of and accruals on legal matters made in the normal course
of our business would not be considered certain significant items.

rate for the three months ended June 30, 2021, compared with the three months
ended June 30, 2020, was primarily attributable to (i) changes in the
jurisdictional mix of earnings, which includes the impact of the location of
earnings, repatriation costs, operating fluctuations in the normal course of
business and the impact of non-deductible and non-taxable items, and (ii) a $4
million and $1 million discrete tax benefit recorded in the three months ended

share-based payments.
The effective tax rate on adjusted pretax income is 19.5% for the six months
ended June 30, 2021 and 2020. The effective tax rate for the six months ended

Analysis of the condensed consolidated statements of comprehensive income
Substantially all changes in other comprehensive income for the periods
presented are related to foreign currency translation adjustments. These changes
result from the strengthening or weakening of the U.S. dollar as compared to the
currencies in the countries in which we do business. The gains and losses
associated with these changes are deferred on the balance sheet in Accumulated
other comprehensive loss until realized.
Analysis of the condensed consolidated balance sheets
June 30, 2021 vs. December 31, 2020
For a discussion about the changes in Cash and cash equivalents, Short-term
borrowings, and Long-term debt, net of discount and issuance costs, see
"Analysis of financial condition, liquidity and capital resources" below.
Accounts Receivable, less allowance for doubtful accounts increased as a result
of higher sales in the period and the impact of foreign exchange, partially
offset by rebate credits issued to customers and the timing of customer
payments.
Inventories increased as a result of the increase in demand and build-up of
certain products and timing of shipments, partially offset by higher sales than
anticipated for certain products.
Other current assets increased as a result of the timing of tax payments, an
increase in fair value of cross-currency interest rate swaps and an increase in
other prepaid expenses.
Accounts payable decreased as a result of the timing of vendor payments.
Accrued expenses increased as a result of increases in contract rebates, accrued
third-party inventory and other expenses.

                                                                            35 |
--------------------------------------------------------------------------------
  Table of Contents
Accrued compensation and related items decreased primarily due to payment of
2020 annual bonuses to eligible employees and 2020 employee savings plan
contributions, partially offset by the pro rata accrual of similar items for
2021.
The net changes in Noncurrent deferred tax assets, Noncurrent deferred tax
liabilities, Income taxes payable and Other taxes payable primarily reflect
adjustments to the accrual for the income tax provision, the timing of income
tax payments, the tax impact of various acquisitions and the impact of the
remeasurement of deferred taxes as a result of changes in tax rates.
Other current liabilities and Other noncurrent liabilities decreased primarily
due to the mark-to-market adjustments of derivative instruments and a decrease
in deferred compensation related to net investment activity.

Operating activities
Six months ended June 30, 2021 vs. six months ended June 30, 2020
Net cash provided by operating activities was $881 million for the six months
ended June 30, 2021, and $846 million for the six months ended June 30, 2020.
The increase in operating cash flows was primarily attributable to higher cash
earnings, partially offset by the timing of receipts and payments in the
ordinary course of business.
Investing activities
Six months ended June 30, 2021 vs. six months ended June 30, 2020
Our net cash used in investing activities was $202 million for the six months
ended June 30, 2021, compared with net cash used in investing activities of $221
million for the six months ended June 30, 2020. The net cash used in investing
activities for 2021 was primarily due to capital expenditures and acquisitions.
The net cash used in investing activities for 2020 was primarily due to capital
expenditures and acquisitions, partially offset by proceeds from the sale of
assets, including a cash payment received pursuant to an agreement related to
the 2016 sale of certain U.S. manufacturing sites and proceeds from
cross-currency interest rate swaps.
Financing activities
Six months ended June 30, 2021 vs. six months ended June 30, 2020
Our net cash used in financing activities was $629 million for the six months
ended June 30, 2021, compared with net cash provided by financing activities of
$813 million for the six months ended June 30, 2020. The net cash used in
financing activities for 2021 was primarily attributable to the purchase of
treasury shares, the payment of dividends and taxes paid on withholding shares,
partially offset by proceeds in connection with the issuance of common stock
under our equity incentive plan. The net cash provided by financing activities
for 2020 was primarily attributable to the proceeds received from the issuance
of senior notes in May 2020 and net proceeds in connection with the issuance of
common stock under our equity incentive plan, partially offset by the purchase
of treasury shares and the payment of dividends.
Analysis of financial condition, liquidity and capital resources
While we believe our cash and cash equivalents on hand, our operating cash flows
and our existing financing arrangements will be sufficient to support our future
cash needs, this may be subject to the environment in which we operate. Risks to
our ability to meet future funding requirements include global economic
conditions described in the following paragraph.
Global financial markets may be impacted by macroeconomic, business and
financial volatility. As markets change, we will continue to monitor our
liquidity position, but there can be no assurance that a challenging economic
environment or an economic downturn will not impact our liquidity or our ability
to obtain future financing.

(a)  Accounts receivable are usually collected over a period of 45 to 75 days.
For the six months ended June 30, 2021, compared with December 31, 2020, the
number of days that accounts receivables are outstanding remained within this
range. We regularly monitor our accounts receivable for collectability,
particularly in markets where economic conditions remain uncertain. We believe
that our allowance for doubtful accounts is appropriate. Our assessment is based
on such factors as past due aging, historical and expected collection patterns,
the financial condition of our customers, the robust nature of our credit and
collection practices and the economic environment.
For additional information about the sources and uses of our funds, see the
Analysis of the condensed consolidated balance sheets and Analysis of the
condensed consolidated statements of cash flows sections of this MD&A.
Credit facility and other lines of credit
In December 2016, we entered into an amended and restated revolving credit
agreement with a syndicate of banks providing for a multi-year $1.0 billion
senior unsecured revolving credit facility (the credit facility). In December
2018, the maturity for the amended and restated credit facility was extended
through December 2023. Subject to certain conditions, we have the right to
increase the credit facility to up to $1.5 billion. The credit facility contains
a financial covenant requiring us to not exceed a maximum total leverage ratio
(the ratio of consolidated net debt as of the end of the period to consolidated
Earnings Before Interest, Income Taxes, Depreciation and Amortization (EBITDA)
for such period) of 3.50:1. Upon entering into a material acquisition, the
maximum total leverage ratio increases to 4.00:1, and extends until the fourth
full consecutive fiscal quarter ended immediately following the consummation of
a material acquisition.
The credit facility also contains a financial covenant requiring that we
maintain a minimum interest coverage ratio (the ratio of EBITDA at the end of
the period to interest expense for such period) of 3.50:1. In addition, the
credit facility contains other customary covenants.
We were in compliance with all financial covenants as of June 30, 2021 and
December 31, 2020. There were no amounts drawn under the credit facility as of
June 30, 2021 or December 31, 2020.
We have additional lines of credit and other credit arrangements with a group of
banks and other financial intermediaries for general corporate purposes. We
maintain cash and cash equivalent balances in excess of our outstanding
short-term borrowings. As of June 30, 2021, we had access to $79 million of
lines of credit which expire at various times through 2021 and are generally
renewed annually. There were $4 million of borrowings outstanding related to
these facilities as of June 30, 2021 and December 31, 2020.
Domestic and international short-term funds
Many of our operations are conducted outside the U.S. The amount of funds held
in the U.S. will fluctuate due to the timing of receipts and payments in the
ordinary course of business and due to other reasons, such as business
development activities. As part of our ongoing liquidity assessments, we
regularly monitor the mix of U.S. and international cash flows (both inflows and
outflows). Actual repatriation of overseas funds can result in additional U.S.
and local income taxes, such as U.S. state income taxes, local withholding
taxes, and taxes on currency gains and losses.
Global economic conditions
Challenging economic conditions in recent years have not had, nor do we
anticipate that it will have, a significant impact on our liquidity. Due to our
operating cash flows, financial assets, access to capital markets and available
lines of credit and revolving credit agreements, we continue to believe that we
have the ability to meet our liquidity needs for the foreseeable future. As
markets change, we continue to monitor our liquidity position. There can be no
assurance that a challenging economic environment or an economic downturn would
not impact our ability to obtain financing in the future.
Debt
On May 12, 2020, we issued $1.25 billion aggregate principal amount of our
senior notes (2020 senior notes), with an original issue discount of $10
million. These notes are comprised of $750 million aggregate principal amount of
2.000% senior notes due 2030 and $500 million aggregate principal amount of
3.000% senior notes due 2050. On October 13, 2020, the net proceeds were used to
repay in full the aggregate principal amount of our 3.450% 2015 senior notes due
2020 and the remainder will be used for general corporate purposes.
On August 20, 2018, we issued $1.5 billion aggregate principal amount of our
senior notes (2018 senior notes), with an original issue discount of $4 million.
On September 12, 2017, we issued $1.25 billion aggregate principal amount of our
senior notes (2017 senior notes), with an original issue discount of $7 million.
On November 13, 2015, we issued $1.25 billion aggregate principal amount of our
senior notes (2015 senior notes), with an original issue discount of $2 million.
On January 28, 2013, we issued $3.65 billion aggregate principal amount of our
senior notes (2013 senior notes) in a private placement, with an original issue
discount of $10 million.
The 2013, 2015, 2017, 2018 and 2020 senior notes are governed by an indenture
and supplemental indenture (collectively, the indenture) between us and Deutsche
Bank Trust Company Americas, as trustee. The indenture contains certain
covenants, including limitations on our and certain of our

                                                                            37 |

subsidiaries' ability to incur liens or engage in sale lease-back transactions.
The indenture also contains restrictions on our ability to consolidate, merge or
sell substantially all of our assets. In addition, the indenture contains other
customary terms, including certain events of default, upon the occurrence of
which (if not cured or waived), the 2013, 2015, 2017, 2018 and 2020 senior notes
may be declared immediately due and payable.
Pursuant to the indenture, we are able to redeem the 2013, 2015, 2017 and 2020
senior notes and the 2018 fixed rate senior notes of any series, in whole or in
part, at any time by paying a "make whole" premium, plus accrued and unpaid
interest to, but excluding, the date of redemption. The 2018 floating rate
senior notes are not redeemable at our option prior to their maturity date.
Pursuant to our tax matters agreement with Pfizer, we will not be permitted to
redeem the 2013 senior notes due 2023 pursuant to this optional redemption
provision, except under limited circumstances. Upon the occurrence of a change
of control of us and a downgrade of the 2013, 2015, 2017, 2018 and 2020 senior
notes below an investment grade rating by each of Moody's Investors Service,
Inc. and Standard & Poor's Ratings Services, we are, in certain circumstances,
required to make an offer to repurchase all of the outstanding 2013, 2015, 2017,
2018 and 2020 senior notes at a price equal to 101% of the aggregate principal
amount of the 2013, 2015, 2017, 2018 and 2020 senior notes together with accrued
and unpaid interest to, but excluding, the date of repurchase.

Credit Ratings
Two major corporate debt-rating organizations, Moody's and S&P, assign ratings
to our short-term and long-term debt. A security rating is not a recommendation
to buy, sell or hold securities and the rating is subject to revision or
withdrawal at any time by the rating organization. Each rating should be
evaluated independently of any other rating.
The following table provides the current ratings assigned by these rating
agencies to our commercial paper and senior unsecured non-credit-enhanced

Share Repurchase Program
In December 2018, the company's Board of Directors authorized a $2.0 billion
share repurchase program. As of June 30, 2021, there was approximately $1.1
billion remaining under this authorization. Purchases of Zoetis shares may be
made at the discretion of management, depending on market conditions and
business needs. Share repurchases may be executed through various means,
including open market or privately negotiated transactions. We temporarily
suspended share repurchases beginning in the second quarter of 2020. In January
2021, the company resumed share repurchases under its share repurchase program.
During the first six months of 2021, approximately 2.1 million shares were
repurchased.

                                                                            38 |

Off-balance sheet arrangements
In the ordinary course of business and in connection with the sale of assets and
businesses, we may indemnify our counterparties against certain liabilities that
may arise in connection with a transaction or that are related to activities
prior to a transaction. These indemnifications typically pertain to
environmental, tax, employee and/or product-related matters, and
patent-infringement claims. If the indemnified party were to make a successful
claim pursuant to the terms of the indemnification, we would be required to
reimburse the loss. These indemnifications are generally subject to threshold
amounts, specified claim periods and other restrictions and limitations.
Historically, we have not paid significant amounts under these provisions and,
as of June 30, 2021, or December 31, 2020, recorded amounts for the estimated
fair value of these indemnifications are not significant.

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