The following discussion should be read in conjunction with the consolidated
financial statements and related notes included elsewhere in this report. Refer
to Part II, Item 7 in our Annual Report on Form 10-K for the fiscal year ended
December 31, 2018 (filed with the SEC on February 7, 2019) for additional
discussion of our financial condition and results of operations for the year
ended December 31, 2017, as well as our financial condition and results of
operations for the year ended December 31, 2018 compared to the year ended
December 31, 2017.
Overview
We are a fully integrated biotechnology company that discovers, invents,
develops, manufactures, and commercializes medicines for the treatment of
serious diseases. Our commercialized medicines and product candidates in
development are designed to help patients with eye diseases, allergic and
inflammatory diseases, cancer, cardiovascular and metabolic diseases, pain,
infectious diseases, and rare diseases.
As described in Part I, Item 1. "Business," we currently have seven products
that have received marketing approval and 22 product candidates in clinical
development, all of which were discovered in our research laboratories. Refer to
Part I, Item 1. "Business" for a summary of our clinical programs.
Our ability to generate profits and to generate positive cash flow from
operations over the next several years depends significantly on the continued
success in commercializing EYLEA and Dupixent. We expect to continue to incur
substantial expenses related to our research and development activities, a
portion of which we expect to be reimbursed by our collaborators. Also, our
research and development activities outside our collaborations, the costs of
which are not reimbursed, are expected to expand and require additional
resources. We also expect to incur substantial costs related to the
commercialization of EYLEA, Dupixent, and Libtayo. Our financial results may
fluctuate from quarter to quarter and will depend on, among other factors, the
net sales of our marketed products; the scope and progress of our research and
development efforts; the timing of certain expenses; the continuation of our
collaborations, in particular with Sanofi and Bayer, including our share of
collaboration profits or losses from sales of commercialized products and the
amount of reimbursement of our research and development expenses that we receive
from collaborators; and the amount of income tax expense we incur, which is
partly dependent on the profits or losses we earn in each of the countries in
which we operate. We cannot predict whether or when new products or new
indications for marketed products will receive regulatory approval or, if any
such approval is received, whether we will be able to successfully commercialize
such product(s) and whether or when they may become profitable.
Critical Accounting Policies and Use of Estimates
A summary of the significant accounting policies that impact us is provided in
Note 1 to our Consolidated Financial Statements. The preparation of financial
statements in accordance with accounting principles generally accepted in the
United States of America ("GAAP") requires management to make estimates and
assumptions that affect reported amounts and related disclosures in the
financial statements. Management considers an accounting estimate to be critical
if:
• it requires an assumption (or assumptions) regarding a future outcome; and


• changes in the estimate or the use of different assumptions to prepare the


       estimate could have a material effect on our results of operations or
       financial condition.


Management believes the current assumptions used to estimate amounts reflected
in our Consolidated Financial Statements are appropriate. However, if actual
experience differs from the assumptions used in estimating amounts reflected in
our Consolidated Financial Statements, the resulting changes could have a
material adverse effect on our results of operations, and, in certain
situations, could have a material adverse effect on our liquidity and financial
condition. The critical accounting estimates that impact our Consolidated
Financial Statements are described below.

Revenue Recognition
During the first quarter of 2018, we adopted Accounting Standards Codification
("ASC") 606, Revenue from Contracts with Customers. Under the terms of the new
standard, revenue is measured as the amount of consideration we expect to be
entitled to in exchange for transferring promised goods or providing services to
a customer, and is recognized when (or as) we satisfy performance obligations
under the terms of a contract.
Product Revenue
Product sales consist of U.S. net product sales of EYLEA, Libtayo, and ARCALYST.
We record revenue from product sales upon delivery to our distributors and
specialty pharmacies (collectively, our "customers"). Revenue from product sales
is recognized at a point in time when our customer is deemed to have obtained
control of the product, which generally occurs upon receipt by our customer.
The amount of revenue we recognize from product sales varies due to rebates,
chargebacks, and discounts provided under governmental and other programs,
distribution-related fees, and other sales-related deductions. In order to
determine the transaction price, we estimate, utilizing the expected value
method, the amount of variable consideration that we will be entitled to. This
estimate is based upon contracts with customers and government agencies,
statutorily-defined discounts applicable to government-funded programs,
historical experience, estimated payor mix, and other relevant factors.
Calculating these provisions involves estimates and judgments. We review our
estimates of rebates, chargebacks, and other applicable provisions each period
and record any necessary adjustments in the current period's net product sales.
Refer to the "Results of Operations - Revenues - Net Product Sales" section
below for further details regarding our provisions, and credits/payments, for
sales-related deductions.
Collaboration Revenue
We have entered into various agreements related to our activities to research,
develop, manufacture, and commercialize product candidates and utilize our
technology platforms. Depending on the terms of the arrangement, we may defer
the recognition of all or a portion of the consideration received because the
performance obligations are satisfied over time.
Our collaboration agreements may require us to deliver various rights, services,
and/or goods across the entire life cycle of a product or product candidate. In
agreements involving multiple goods or services promised to be transferred to a
customer, we must assess, at the inception of the contract, whether each promise
represents a separate performance obligation (i.e., is "distinct"), or whether
such promises should be combined as a single performance obligation.
At the inception of the contract, the transaction price reflects the amount of
consideration we expect to be entitled to in exchange for transferring promised
goods or services to our customer. We review our estimate of the transaction
price each period and make revisions to such estimates as necessary. In
arrangements where we satisfy performance obligation(s) during the development
phase over time, we recognize collaboration revenue over time typically using an
input method on the basis of our research and development costs incurred
relative to the total expected cost which determines the extent of our progress
toward completion. Due to the variability in the scope of activities and length
of time necessary to develop a drug product, potential delays in development
programs, changes to development plans and budgets as programs progress,
including if we and our collaborators decide to expand or contract our clinical
plans for a drug candidate in various disease indications, and uncertainty in
the ultimate requirements to obtain governmental approval for commercialization,
revisions to our estimates are likely to occur periodically, and could result in
material changes to the amount of revenue recognized each year in the future.
When we are entitled to reimbursement of all or a portion of the research and
development expenses that we incur under a collaboration, we record those
reimbursable amounts proportionately as we recognize our expenses. If the
collaboration is a cost-sharing arrangement in which both we and our
collaborator perform development work and share costs, we also recognize, as
research and development expense in the period when our collaborator incurs
development expenses, a portion of the collaborator's development expenses that
we are obligated to reimburse. Our collaborators provide us with estimated
development expenses for the most recent fiscal quarter. Our collaborators'
estimates are reconciled to their actual expenses for such quarter in the
subsequent fiscal quarter, and our portion of our collaborators' development
expenses that we are obligated to reimburse is adjusted on a prospective basis
accordingly, as necessary.
Under certain of our collaboration agreements, product sales and cost of sales
may be recorded by our collaborators as they are deemed to be the principal in
the transaction. We share in any profits or losses arising from the
commercialization of such products, and record our share of the variable
consideration, representing net product sales less cost of goods sold and shared
commercialization and other expenses, as collaboration revenue in the period in
which such underlying sales occur and costs are incurred by the collaborator.
Our collaborator provides us with our estimated share of the profits or losses
from commercialization of such products for the most recent fiscal quarter. Our
collaborators' estimates of profits or losses for such quarter are reconciled to
actual profits or losses in the subsequent fiscal quarter, and our share of the
profit or loss is adjusted on a prospective basis accordingly, as necessary.

In arrangements where the collaborator records product sales, we may be
obligated to use commercially reasonable efforts to supply commercial product to
our collaborators and may be reimbursed for our manufacturing costs as
commercial product is shipped to our collaborators; however, recognition of such
cost reimbursements as collaboration revenue is deferred until the product is
sold by our collaborators to third-party customers.
Stock-based Compensation
We recognize stock-based compensation expense for grants under our long-term
incentive plans to employees and non-employee members of our board of directors
based on the grant-date fair value of those awards. The grant-date fair value of
an award is generally recognized as compensation expense over the award's
requisite service period.
We use the Black-Scholes model to compute the estimated fair value of stock
option awards. Using this model, fair value is calculated based on assumptions
with respect to (i) expected volatility of our Common Stock price, (ii) the
periods of time over which employees and members of our board of directors are
expected to hold their options prior to exercise (expected lives), (iii)
expected dividend yield on our Common Stock, and (iv) risk-free interest rates,
which are based on quoted U.S. Treasury rates for securities with maturities
approximating the options' expected lives. Expected volatility has been
estimated based on actual movements in our stock price over the most recent
historical periods equivalent to the options' expected lives. Expected lives are
principally based on our historical exercise experience with previously issued
employee and board of directors option grants. The expected dividend yield is
zero as we have never paid dividends and do not currently anticipate paying any
in the foreseeable future.
Stock-based compensation expense also includes an estimate, which is made at the
time of grant, of the number of awards that are expected to be forfeited. This
estimate is revised, if necessary, in subsequent periods if actual forfeitures
differ from those estimates.
The assumptions used in computing the fair value of stock option awards reflect
our best estimates but involve uncertainties related to market and other
conditions, many of which are outside of our control. Changes in any of these
assumptions may materially affect the fair value of stock option awards granted
and the amount of stock-based compensation recognized in future periods.
Income Taxes
We recognize deferred tax assets and liabilities for the expected future tax
consequences of events that have been included in the financial statements or
tax returns, including deferred tax assets and liabilities for expected amounts
of global intangible low-taxed income ("GILTI") inclusions. Deferred tax assets
and liabilities are determined as the difference between the tax basis of assets
and liabilities and their respective financial reporting amounts ("temporary
differences") at enacted tax rates in effect for the years in which the
differences are expected to reverse. A valuation allowance is established for
deferred tax assets for which it is more likely than not that some portion or
all of the deferred tax assets will not be realized. We periodically re-assess
the need for a valuation allowance against our deferred tax assets based on all
available evidence, including scheduled reversals of deferred tax liabilities,
projected future taxable income, tax planning strategies, results of recent
operations, and our historical earnings experience by taxing jurisdiction.
Significant judgment is required in making this assessment.
Uncertain tax positions, for which management's assessment is that there is more
than a 50% probability of sustaining the position upon challenge by a taxing
authority based upon its technical merits, are subjected to certain recognition
and measurement criteria. Significant judgment is required in making this
assessment, and, therefore, we re-evaluate uncertain tax positions and consider
various factors, including, but not limited to, changes in tax law, the
measurement of tax positions taken or expected to be taken in tax returns, and
changes in facts or circumstances related to a tax position. We adjust the level
of the liability to reflect any subsequent changes in the relevant facts and
circumstances surrounding the uncertain positions.
Inventories
We capitalize inventory costs associated with our products prior to regulatory
approval when, based on management's judgment, future commercialization is
considered probable and the future economic benefit is expected to be realized;
otherwise, such costs are expensed. The determination to capitalize inventory
costs is based on various factors, including status and expectations of the
regulatory approval process, any known safety or efficacy concerns, potential
labeling restrictions, and any other impediments to obtaining regulatory
approval.
We periodically analyze our inventory levels to identify inventory that may
expire prior to expected sale or has a cost basis in excess of its estimated
realizable value, and write-down such inventories as appropriate. In addition,
our products are subject to strict quality control and monitoring which we
perform throughout the manufacturing process. If certain batches or units of
product no longer meet quality specifications or become obsolete due to
expiration, we record a charge to write down such unmarketable inventory to its
estimated realizable value.

Contingencies


We accrue, based on management's judgment, for an estimated loss when the
potential loss from claims or legal proceedings is considered probable and the
amount can be reasonably estimated. As additional information becomes available,
or, based on specific events such as the outcome of litigation or settlement of
claims, we reassess the potential liability related to pending claims and
litigation, and may change our estimates.

Net Product Sales
Net product sales of EYLEA in the United States increased in 2019 compared to
2018 due to higher sales volume, partly offset by an increase in sales-related
deductions primarily due to higher rebates and discounts. On September 28, 2018,
the FDA approved Libtayo for the treatment of patients with metastatic or
locally advanced CSCC and sales commenced thereafter.
Revenue from product sales is recorded net of applicable provisions for rebates,
chargebacks, and discounts; distribution-related fees; and other sales-related
deductions. The following table summarizes the provisions, and credits/payments,
for sales-related deductions.

* Global net product sales of Dupixent, Praluent, and Kevzara are recorded by Sanofi ** Percentage not meaningful




We and Sanofi share commercial expenses related to Dupixent, Praluent, and
Kevzara in accordance with the companies' License and Collaboration Agreement.
As such, during the same periods in which we recorded reimbursements from Sanofi
related to our commercialization expenses, we also recorded our share of
combined profits/losses in connection with the companies' commercialization of
Dupixent, Praluent, and Kevzara within Sanofi collaboration revenue. During
2019, Sanofi collaboration revenues in connection with commercialization of
antibodies increased, compared to 2018, primarily due to our share of higher
Dupixent profits. See Part I, Item 1. "Business - Marketed Products" for a
summary of global net product sales recorded by Sanofi in connection with our
Antibody License and Collaboration Agreement.
In December 2019, we and Sanofi announced our intent to restructure the antibody
collaboration for Kevzara and Praluent; completion of the proposed arrangement
is expected to be finalized in the first quarter of 2020. Refer to Part I, Item
1. "Business - Collaboration Agreements - Collaborations with Sanofi - Antibody"
for further details.
Immuno-Oncology
Sanofi's reimbursement of immuno-oncology research and development costs under
our IO Discovery Agreement decreased in 2019, compared to 2018 and 2017, due to
the impact of the Amended IO Discovery Agreement (see Part I, Item 1. "Business
- Collaboration Agreements - Collaborations with Sanofi - Immuno-Oncology for
further details). In 2018, we also recorded cumulative catch-up adjustments to
revenue of $135.0 million (included in "Amounts recognized in connection with
up-front payments received" in the Sanofi collaboration revenue table above)
arising from changes in the estimate of the stage of completion of the
collaborations' immuno-oncology programs, primarily in connection with the
Amended IO Discovery Agreement.

In addition to Teva collaboration revenue (which is earned in connection with
the development of fasinumab), "Other revenue" in the table above includes, but
is not limited to:
•      recognition of a portion of deferred revenue from up-front and other
       payments received from MTPC in connection with our fasinumab
       collaboration;

• Sanofi's reimbursement for manufacturing commercial supplies of ZALTRAP

and a percentage of aggregate net sales of ZALTRAP under the terms of the

Amended ZALTRAP Agreement;

• royalties in connection with a June 2009 agreement with Novartis, under

which we receive royalties on worldwide sales of Novartis' Ilaris®

(canakinumab). The royalty rates in the agreement start at 4% and reach


       15% when annual sales exceed $1.5 billion, and we are entitled to
       royalties until Novartis ceases sale of products subject to royalty;

• recognition of revenue in connection with our agreements with BARDA

related to REGN-EB3 for the treatment of Ebola;

• recognition of revenue in connection with sequencing of samples by the RGC


       for its customers.



Other revenue of $416.8 million in 2018 also included the impact of adopting ASC 606, Revenue from Contracts with Customers, as the new standard resulted in certain changes to the timing of revenue recognition related to our collaboration agreements. Amounts in periods prior to 2018 have not been adjusted in connection with the adoption of this standard.

(1) Cost of goods sold includes costs in connection with producing commercial supplies for products that are sold
by Regeneron in the United States (i.e., EYLEA, Libtayo, and ARCALYST) and any royalties we are obligated to pay
on such sales, period costs for our Limerick manufacturing facility, and amounts we are obligated to pay to
Sanofi for its share of Libtayo U.S. gross profits.
(2) Cost of collaboration and contract manufacturing primarily includes costs we incur in connection with
producing commercial drug supplies for Sanofi and Bayer.


Operating expenses in 2019, 2018, and 2017 included a total of $464.3 million,
$427.4 million, and $507.3 million, respectively, of non-cash compensation
expense related to awards granted under our long-term incentive plans. Non-cash
compensation expense in 2019 and 2018 benefited from a revision in our estimate
of the number of stock options that were expected to be forfeited. As of
December 31, 2019, unrecognized non-cash compensation expense related to
outstanding stock options and unvested restricted stock was $521.9 million and
$274.6 million, respectively. We expect to recognize this non-cash compensation
expense related to stock options and restricted stock over weighted-average
periods of 1.9 years and 3.4 years, respectively.
Research and Development Expenses
The following table summarizes our estimates of direct research and development
expenses by clinical development program and other significant categories of
research and development expenses. Direct research and development expenses are
comprised primarily of costs paid to third parties for clinical and product
development activities, including costs related to preclinical research
activities, clinical trials, and the portion of research and development
expenses incurred by our collaborators that we are obligated to reimburse.
Indirect research and development expenses have not been allocated directly to
each program, and primarily consist of costs to compensate personnel, overhead
and infrastructure costs to maintain our facilities, and other costs related to
activities that benefit multiple projects. Clinical manufacturing costs
primarily consist of costs to manufacture bulk drug product for clinical
development purposes as well as related external drug filling, packaging, and
labeling costs. Clinical manufacturing costs also includes pre-launch commercial
supplies which did not meet the criteria to be capitalized as inventory (see
"Critical Accounting Policies and Use of Estimates - Inventories" above).

Research and development expenses in 2019 included a $400.0 million up-front
payment to Alnylam (see Part I, Item 1. "Collaboration Agreements -
Collaboration with Alnylam" for further information). Research and development
expenses included non-cash compensation expense of $250.4 million, $229.0
million, and $271.9 million in 2019, 2018, and 2017, respectively.
There are numerous uncertainties associated with drug development, including
uncertainties related to safety and efficacy data from each phase of drug
development, uncertainties related to the enrollment and performance of clinical
trials, changes in regulatory requirements, changes in the competitive landscape
affecting a product candidate, and other risks and uncertainties described in
Part I, Item 1A. "Risk Factors." There is also variability in the duration and
costs necessary to develop a pharmaceutical product, potential opportunities
and/or uncertainties related to future indications to be studied, and the
estimated cost and scope of the projects. The lengthy process of seeking FDA and
other applicable approvals, and subsequent compliance with applicable statutes
and regulations, require the expenditure of substantial resources. Any failure
by us to obtain, or delay in obtaining, regulatory approvals could materially
adversely affect our business. We are unable to reasonably estimate if our
product candidates in clinical development will generate material product
revenues and net cash inflows.
Selling, General, and Administrative Expenses
Selling, general, and administrative expenses increased in 2019, compared to
2018, primarily due to higher headcount and headcount-related costs, an increase
in commercialization-related expenses for Dupixent and EYLEA, additional
accruals for loss contingencies associated with ongoing litigation, and higher
contributions to independent not-for-profit patient assistance organizations. In
addition, in the fourth quarter of 2019, we recorded a $35.2 million charge
related to employee separation costs, as the Company has eliminated certain
commercialization activities and related headcount in connection with the
proposed restructuring of the antibody agreement with Sanofi (as described in
Part I, Item 1. "Business - Collaboration Agreements - Collaborations with
Sanofi - Antibody"). Selling, general, and administrative expenses also included
$167.7 million, $169.2 million, and $208.4 million of non-cash compensation
expense in 2019, 2018, and 2017, respectively.

Table of Contents



Cost of Goods Sold
Cost of goods sold increased in 2019, compared to 2018, primarily due to Libtayo
sales in the United States, including (i) our obligation to pay Sanofi its share
of Libtayo U.S.gross profits and (ii) third-party royalties. In addition, Cost
of goods sold for the years ended December 31, 2019 and 2018 included inventory
write-downs and reserves totaling $73.8 million and $12.5 million, respectively.
Cost of Collaboration and Contract Manufacturing
The increase in Cost of collaboration and contract manufacturing in 2019,
compared to 2018, was primarily due to the recognition of manufacturing costs
associated with higher sales of Dupixent.
Other Income (Expense)
Other income (expense), net, was positively impacted in 2019 by the recognition
of unrealized gains on equity securities. Other income (expense), net, in 2019,
compared to 2018, was also positively impacted by increased interest income
earned on available-for-sale debt securities primarily due to higher average
investment balances.
In the first quarter of 2018, we adopted Accounting Standards Update ("ASU")
2016-01, Recognition and Measurement of Financial Assets and Financial
Liabilities, which requires us to measure equity investments at fair value with
changes in fair value recognized in net income; previously, such changes in fair
value were recognized in Other comprehensive income (loss).
Income Taxes
                                                Year Ended December 31,
(In millions, except effective tax rate)     2019        2018        2017
Income tax expense                         $ 313.3     $ 109.1     $ 880.0
Effective tax rate                            12.9 %       4.3 %      42.3 %


Our effective tax rate for 2019 was positively impacted, compared to the U.S.
federal statutory rate, primarily by federal tax credits for research
activities, stock-based compensation, and the foreign-derived intangible income
deduction. Our effective tax rate for 2018 was positively impacted, compared to
the U.S. federal statutory rate, primarily by the sale of non-inventory related
assets between foreign subsidiaries (for which we recorded a $162.1 million net
income tax benefit), and, to a lesser extent, the federal tax credit for
research activities, stock-based compensation, income earned in foreign
jurisdictions with tax rates lower than the U.S. federal statutory rate, and tax
planning in connection with the bill known as the "Tax Cuts and Jobs Act" (the
"Act") (as further described below).
In December 2017, the Act was signed into law. The Act, which became effective
with respect to most of its provisions as of January 1, 2018, included a number
of provisions that impact us, including reducing the U.S. federal corporate
income tax rate from 35% to 21%, changing the taxation of foreign earnings
(including taxation of certain global intangible low-taxed income), allowing for
a foreign-derived intangible income deduction and immediate expensing of the
cost for qualified assets, repealing the deduction for domestic manufacturing,
and imposing further limitations on the deductibility of executive compensation.
As a result of the Act being signed into law, we recognized a provisional charge
of $326.2 million in the fourth quarter of 2017 related to the re-measurement of
our U.S. net deferred tax assets at the lower enacted corporate tax rate. The
provisional charge recorded in the fourth quarter of 2017 was an estimate and
was subject to further analysis, interpretation, and clarification of the Act.
During 2018, we recorded an income tax benefit of $68.0 million as a final
adjustment to the provisional amount recorded as of December 31, 2017.

Cash Flows from Operating Activities
2019
Our net income of $2.116 billion in 2019 was negatively impacted by an up-front
payment of $400.0 million made to Alnylam pursuant to our collaboration
agreement. Our net income in 2019 was impacted by several non-cash items,
including unrealized gains (net) on equity securities and inventory write-downs
and reserves (see "Results of Operations" above), as well as the impact of
Sanofi satisfying its Libtayo development funding obligation in shares of
Regeneron stock (see "Sanofi Funding of Certain Development Costs" below).
Deferred taxes as of December 31, 2019 increased by $130.6 million, compared to
December 31, 2018, primarily due to the tax treatment of the up-front payment
made to Alnylam and non-cash compensation expense. Deferred revenue as of
December 31, 2019 increased compared to December 31, 2018 partially due to the
impact of the receipt of a $461.9 million payment from Sanofi in connection with
the termination of the 2015 IO Discovery Agreement (as described in Part I, Item
1. "Collaboration Agreements - Collaborations with Sanofi - Immuno-Oncology").
2018
Our net income of $2.444 billion in 2018 included the recognition of cumulative
catch-up adjustments of $135.0 million within revenue primarily in connection
with the termination of the 2015 IO Discovery Agreement and other non-cash
items, including $75.8 million in connection with Sanofi satisfying its Libtayo
development funding obligation in shares of Regeneron stock and $41.9 million
related to unrealized losses (net) on equity securities. Deferred tax assets as
of December 31, 2018 increased by $140.0 million, compared to December 31, 2017,
primarily due to the impact of the Company's sale of non-inventory related
assets between foreign subsidiaries.
Cash Flows from Investing Activities
In 2019, we purchased $400.0 million of Alnylam common stock in connection with
entering into the collaboration agreement. Capital expenditures in 2019 included
costs associated with the expanding our manufacturing facilities in Rensselaer,
New York and Limerick, Ireland, including the initiation of the construction of
a fill/finish facility.

                                       70

--------------------------------------------------------------------------------

Table of Contents



We expect to incur capital expenditures of $520 million to $620 million in 2020
primarily in connection with the continued expansion of our manufacturing
facilities, including the fill/finish facility and equipment, and laboratory
expansion and renovations at our Tarrytown, New York facilities.
Cash Flows from Financing Activities
During 2019, we paid an aggregate of $275.9 million to purchase shares of our
Common Stock. See further descriptions under "Share Repurchase Program" and
"Sanofi Funding of Certain Development Costs" below.
Credit Facility
In December 2018, we entered into an agreement with a syndicate of lenders (the
"Credit Agreement") which provides for a $750.0 million senior unsecured
five-year revolving credit facility (the "Credit Facility"), and
contemporaneously terminated our then-existing credit agreement (the "Prior
Credit Agreement"). The Credit Agreement was entered into on terms substantially
similar to those of the Prior Credit Agreement. No borrowings were outstanding
under the Prior Credit Agreement at the time of its termination.
The Credit Agreement includes an option for us to elect to increase the
commitments under the Credit Facility and/or to enter into one or more tranches
of term loans in the aggregate principal amount of up to $250.0 million, subject
to the consent of the lenders providing the additional commitments or term
loans, as applicable, and certain other conditions. Proceeds of the loans under
the Credit Facility may be used to finance working capital needs, and for
general corporate or other lawful purposes, of Regeneron and its subsidiaries.
The Credit Agreement also provides a $50.0 million sublimit for letters of
credit. The Credit Agreement includes an option for us to elect to extend the
maturity date of the Credit Facility beyond December 2023, subject to the
consent of the extending lenders and certain other conditions. Amounts borrowed
under the Credit Facility may be prepaid, and the commitments under the Credit
Facility may be terminated, at any time without premium or penalty. We had no
borrowings outstanding under the Credit Facility as of December 31, 2019.
The Credit Agreement contains financial and operating covenants. Financial
covenants include a maximum total leverage ratio and a minimum interest expense
coverage ratio. We were in compliance with all covenants of the Credit Facility
as of December 31, 2019.
Share Repurchase Program
In November 2019, our board of directors authorized a share repurchase program
to repurchase up to $1.0 billion of our Common Stock. The share repurchase
program permits the Company to effect repurchases through a variety of methods,
including open-market transactions (including pursuant to a trading plan adopted
in accordance with Rule 10b5-1 of the Exchange Act), privately negotiated
transactions, accelerated share repurchases, block trades, and other
transactions in compliance with Rule 10b-18 of the Exchange Act. Repurchases may
be made from time to time at management's discretion, and the timing and amount
of any such repurchases will be determined based on share price, market
conditions, legal requirements, and other relevant factors. The program has no
time limit and can be discontinued at any time. There can be no assurance as to
the timing or number of shares of any repurchases in the future. We plan to
finance the share repurchase program with available cash.
During 2019, we repurchased 722,596 shares of our Common Stock under the program
and recorded the cost of the shares received, or $254.0 million, as Treasury
Stock.
Sanofi Funding of Certain Development Costs
As described in Part I, Item 1. "Business - Collaborations - Collaborations with
Sanofi," effective January 7, 2018, we have agreed to allow Sanofi to satisfy in
whole or in part its funding obligations with respect to Libtayo development
and/or Dupilumab/REGN3500 Eligible Investments by selling up to an aggregate of
1,400,000 shares (of which 869,828 shares remain available to be sold as of
December 31, 2019) of our Common Stock directly or indirectly owned by Sanofi.
During 2019, Sanofi elected to sell, and we elected to purchase (by issuing a
credit towards the amount owed by Sanofi), 210,733 shares of the Company's
Common Stock to satisfy Sanofi's funding obligation related to Libtayo
development costs. Consequently, we recorded $73.3 million related to the shares
received as Treasury Stock during 2019. In addition, during 2019, Sanofi elected
to sell, and we elected to purchase (in cash), 93,286 shares of the Company's
Common Stock in connection with Sanofi's funding obligation for
Dupilumab/REGN3500 Eligible Investments. Consequently, we recorded the cost of
the shares received, or $29.4 million, as Treasury Stock during 2019.

Tarrytown, New York Leases
We lease laboratory and office facilities in Tarrytown, New York (the
"Facility"). In 2016, we entered into a Purchase Agreement with the then lessor,
pursuant to which we agreed to purchase the Facility for a purchase price of
$720.0 million. In March 2017, we entered into a Participation Agreement with
Banc of America Leasing & Capital LLC ("BAL"), as lessor, and a syndicate of
lenders (collectively, the "Lease Participants"), which provided for lease
financing in connection with the acquisition by BAL of the Facility and our
lease of the Facility from BAL. In March 2017, we assigned our right to take
title to the Facility under the Purchase Agreement to BAL, and the Lease
Participants advanced $720.0 million, which was used by BAL to finance the
purchase price for the Facility.
Concurrent with entering into the Participation Agreement, we also entered into
a lease agreement (the "Lease") for the Facility with BAL for a five-year term.
The Lease requires us to pay all maintenance, insurance, taxes, and other costs
arising out of the use of the Facility. We are also required to make monthly
payments of basic rent during the term of the Lease in an amount equal to a
variable rate per annum based on the one-month LIBOR, plus an applicable margin
that varies with our debt rating and total leverage ratio.
The Participation Agreement and the Lease include an option for us to elect to
extend the maturity date of the Participation Agreement and the term of the
Lease for an additional five-year period, subject to the consent of all the
Lease Participants and certain other conditions. We also have the option prior
to the end of the term of the Lease to (a) purchase the Facility by paying an
amount equal to the outstanding principal amount of the Lease Participants'
advances under the Participation Agreement, all accrued and unpaid interest and
yield thereon, and all other outstanding amounts under the Participation
Agreement, the Lease, and certain related documents or (b) sell the Facility to
a third party on behalf of BAL. The advances under the Participation Agreement
mature, and all amounts outstanding thereunder will become due and payable in
full at the end of the term of the Lease.
The Participation Agreement and the Lease contain financial and operating
covenants, which are substantially similar to the covenants set forth in our
Credit Facility. We were in compliance with all covenants of the Participation
Agreement and the Lease as of December 31, 2019.
Funding Requirements
The amount required to fund operations will depend on various factors, including
revenues from net product sales, the potential regulatory approval and
commercialization of our product candidates and the timing thereof, the status
of competitive products, the success of our research and development programs,
the potential future need to expand our professional and support staff and
facilities, the status of patents and other intellectual property rights (and
future litigation related thereto), the delay or failure of a clinical trial of
any of our potential drug candidates, and the continuation, extent, and success
of our collaborations (in particular those with Sanofi and Bayer). We believe
that our existing capital resources, borrowing availability under the Credit
Facility, funds generated by anticipated EYLEA and Dupixent net product sales,
and, as described above under Part I, Item 1. "Business - Collaborations,"
funding for reimbursement of research and development costs that we are entitled
to receive under our collaboration agreements, will enable us to meet our
anticipated operating needs for the foreseeable future.
The following table summarizes our contractual obligations as of December 31,
2019.
                                                                             Payments Due by Period

(1) Primarily includes research and development commitments, including those related to clinical trials, and capital
expenditures. Our obligation to pay certain of these amounts may increase or be reduced based on relevant future events.
(2) Includes rent payments with respect to finance lease obligations in connection with our property leases in Tarrytown,
New York, as described under "Tarrytown, New York Leases" above and Note 11 to our Consolidated Financial Statements.
Amounts in the table above exclude the purchase price we would be obligated to pay if we were to exercise our option to
purchase the Facility.


Liabilities for unrecognized tax benefits, totaling $210.8 million at
December 31, 2019, are not included in the table of contractual obligations
above as, due to their nature, there is a high degree of uncertainty regarding
the period of potential future cash settlement with taxing authorities. See Note
15 to our Consolidated Financial Statements.
We expect continued increases in our expenditures, particularly in connection
with our research and development activities (including preclinical and clinical
programs). The amount of funding that will be required for our clinical programs
depends upon the results of our research and preclinical programs and
early-stage clinical trials, regulatory requirements, the duration and results
of clinical

                                       72

--------------------------------------------------------------------------------

Table of Contents



trials underway and of additional clinical trials that we decide to initiate,
and the various factors that affect the cost of each trial. Under certain
collaboration agreements, the amount of funding for reimbursement of research
and development costs that we are entitled to receive is capped at a specified
amount; therefore, we may elect to independently fund certain research and
development costs in excess of such capped amounts.
Clinical trial costs are dependent, among other things, on the size and duration
of trials (for example, we have several ongoing late-stage clinical trials which
are large and for which we expect to incur significant costs), fees charged for
services provided by clinical trial investigators and other third parties, the
costs for manufacturing the product candidate for use in the trials, and for
supplies, laboratory tests, and other expenses.
We anticipate continuing to incur substantial commercialization costs for EYLEA,
Dupixent, and Libtayo. Commercialization costs over the next few years will
depend on, among other things, the market potential for product candidates,
whether commercialization costs are shared with a collaborator, and regulatory
approval of additional product candidates.
We expect that expenses related to the filing, prosecution, defense, and
enforcement of patents and other intellectual property will be substantial.
We enter into research collaboration and licensing agreements that may require
us to pay (i) amounts upon the achievement of various development and commercial
milestones, which, in the aggregate, could be significant, and/or (ii) royalties
calculated based on a percentage of net product sales. The payment of these
amounts, however, is contingent upon the occurrence of various future events,
which have a high degree of uncertainty of occurring and for which the specific
timing cannot be predicted. Because of these factors, such payments are not
included in the table of contractual obligations above. See Note 3 and Note 11
to our Consolidated Financial Statements.
Under our Antibody and IO Collaborations with Sanofi and our collaboration with
Bayer for EYLEA outside the United States, we and our collaborator share profits
and losses in connection with commercialization of drug products. Profits or
losses under each collaboration are measured by calculating net sales less cost
of goods sold and shared commercialization and other expenses. If the applicable
collaboration is profitable, we have contingent contractual obligations to
reimburse Sanofi and Bayer for a defined percentage (generally 50%) of
agreed-upon development expenses funded by Sanofi and Bayer. These
reimbursements are deducted each quarter, in accordance with a formula, from our
share of the collaboration profits (and, for our EYLEA collaboration with Bayer,
inclusive of our percentage on product sales in Japan) otherwise payable to us,
unless, in the case of EYLEA, we elect to reimburse these expenses at a faster
rate. As of December 31, 2019, our contingent reimbursement obligation to Bayer
for EYLEA was approximately $270 million and our contingent reimbursement
obligation to Sanofi in connection with the companies' Antibody Collaboration
and IO Collaboration was approximately $2.990 billion and $75 million,
respectively. Therefore, we expect that, for the foreseeable future, a portion
of our share of profits from sales under our collaborations with Bayer and
Sanofi will be used to reimburse our collaborators for these obligations.
Off-Balance Sheet Arrangements
We do not have any off-balance sheet arrangements that are currently material or
reasonably likely to be material to our consolidated financial position or
results of operations.
Future Impact of Recently Issued Accounting Standards
See Note 1 to our Consolidated Financial Statements for a summary of recently
issued accounting standards.
Item 7A. Quantitative and Qualitative Disclosures About Market Risk
Interest Rate Risk
Our earnings and cash flows are subject to fluctuations due to changes in
interest rates, principally in connection with our investments in marketable
securities, which consist primarily of corporate bonds, direct obligations of
the U.S. government and its agencies and other debt securities guaranteed by the
U.S. government, and municipal bonds. We do not believe we are materially
exposed to changes in interest rates related to our investments, and we do not
currently use interest rate derivative instruments to manage exposure to
interest rate changes of our investments. We estimate that a 100 basis point, or
1%, unfavorable change in interest rates would have resulted in approximately a
$48.6 million and $27.7 million decrease in the fair value of our investment
portfolio as of December 31, 2019 and 2018, respectively.

                                       73

--------------------------------------------------------------------------------

Table of Contents



We have exposure to market risk for changes in interest rates, including the
interest rate risk relating to our March 2017 variable rate Tarrytown, New York
lease (as described in Part II, Item 7. "Management's Discussion and Analysis of
Financial Condition and Results of Operations - Liquidity and Capital Resources
- Tarrytown, New York Leases"). Our interest rate exposure is primarily offset
by our investments in marketable securities. In addition, we further manage our
interest rate exposure related to our variable rate lease through the use of
derivative instruments. All of our derivative instruments are utilized for risk
management purposes and are not used for trading or speculative purposes. We
continue to monitor our interest rate risk and may utilize additional derivative
instruments and/or other strategies in the future to further mitigate our
interest rate exposure.
We have hedged a portion of our floating interest rate exposure using interest
rate swap and interest rate cap contracts. We estimate that a 100 basis point,
or 1%, unfavorable change in interest rates would not have a material impact on
the fair value of our interest rate swap or interest rate cap contracts.
Credit Quality Risk
We have an investment policy that includes guidelines on acceptable investment
securities, minimum credit quality, maturity parameters, and concentration and
diversification. Nonetheless, deterioration of the credit quality of an
investment security subsequent to purchase may subject us to the risk of not
being able to recover the full principal value of the security. In 2019, 2018,
and 2017, we did not record any charges for other-than-temporary impairments of
our available-for-sale debt securities.
We are subject to credit risk associated with the receivables due from our
collaborators, including Bayer, Sanofi, and Teva. We are also subject to credit
risk in connection with trade accounts receivable from our product sales. These
trade accounts receivable are primarily due from several distributors and
specialty pharmacies, who are our customers. We have contractual payment terms
with each of our customers, and we monitor our customers' financial performance
and credit worthiness so that we can properly assess and respond to any changes
in their credit profile. During 2019, 2018, and 2017, we did not recognize any
charges for write-offs of accounts receivable related to our marketed products.
As of December 31, 2019 and 2018, three customers accounted on a combined basis
for 97% and 99%, respectively, of our net trade accounts receivables.
Foreign Exchange Risk
As discussed further above, Bayer markets EYLEA outside the United States and
Sanofi markets Dupixent, Praluent, and Kevzara worldwide, and we share in
profits and losses with these collaborators from commercialization of products
(including the receipt of a percentage of EYLEA sales in Japan). In addition,
pursuant to the applicable terms of the agreements with our collaborators, we
also share in certain worldwide development expenses incurred by our
collaborators. We also incur worldwide development expenses for clinical
products we are developing independently, in addition to incurring expenses
outside of the United States in connection with our international operations.
Therefore, significant changes in foreign exchange rates of the countries
outside the United States where our product is sold, where development expenses
are incurred by us or our collaborators, or where we incur operating expenses
can impact our operating results and financial condition. As sales outside the
United States continue to grow, and as we expand our international operations,
we will continue to assess potential steps, including foreign currency hedging
and other strategies, to mitigate our foreign exchange risk.
Market Price Risk
We are exposed to price risk on equity securities included in our investment
portfolio. Our marketable securities include equity investments in publicly
traded stock of companies, including common stock of companies with which we
have entered into collaboration arrangements. Changes in the fair value of our
equity investments are included in Other income (expense), net on the
Consolidated Statements of Income. We recorded $118.3 million of net unrealized
gains and $41.9 million of net unrealized losses on equity securities in Other
income (expense), net for the years ended December 31, 2019 and 2018,
respectively.
Item 8. Financial Statements and Supplementary Data
The financial statements required by this Item are included on pages F-1 through
F-44 of this report. The supplementary financial information required by this
Item is included at page F-44 of this report.
Item 9. Changes in and Disagreements with Accountants on Accounting and
Financial Disclosure
None.
