Overview

Our goal is to discover and develop therapeutics to defeat degeneration.

Our strategy is guided by three overarching principles that we believe will significantly increase the probability of success and will accelerate the timing to bring effective therapeutics to patients with neurodegenerative diseases:

•Genetic Pathway Potential: We select our therapeutic targets and disease pathways based on genes that, when mutated, cause, or are major risk factors for, neurodegenerative diseases. We refer to these genes as degenogenes;

•Engineering Brain Delivery: We engineer our product candidates to cross the BBB and act directly in the brain; and



•Biomarker-Driven Development: We discover, develop and utilize biomarkers to
select the right patient population and demonstrate target engagement, pathway
engagement and impact on disease progression of our product candidates.

We are developing a broad portfolio of targeted therapeutic candidates for neurodegenerative diseases. Our programs are at different stages of clinical and preclinical development, including four programs in clinical studies.



We have also developed a proprietary BBB platform technology, our transport
vehicle ("TV"), which enables multiple modality-based platforms to deliver a
wide range of large-molecule therapeutics across the BBB, including enzymes,
antibodies, proteins and oligonucleotides. This technology is designed to engage
specific BBB transport receptors, which are ubiquitously expressed in brain
capillaries and facilitate transport of proteins into the brain. We are
currently optimizing and broadening this platform technology.

Our four clinical-stage programs are:
•our leucine-rich repeat kinase 2 ("LRRK2") inhibitor program, partnered with
Biogen, to address Parkinson's disease;

•our eukaryotic translation initiation factor 2B ("EIF2B") activator program to address diseases such as ALS and frontotemporal dementia ("FTD");



•our ETV:IDS program, our most advanced program enabled by our enzyme transport
vehicle ("ETV") technology, which is designed to restore iduronate 2-sulfatase
("IDS"), and reduce glycosaminoglycans, both peripherally and in the brain, in
patients with mucopolysaccharidosis II ("MPS II", or "Hunter syndrome"); and

•our receptor interacting serine/threonine protein kinase 1 ("RIPK1") inhibitor
program, partnered with Sanofi, to address peripheral inflammatory diseases such
as cutaneous lupus and COVID-19.

To complement our internal capabilities, we have entered into arrangements with
biopharmaceutical companies, patient-focused data companies, numerous leading
academic institutions and foundations to gain access to new product candidates,
enable and accelerate the development of our existing programs and deepen our
scientific understanding of certain areas of biology. We rely on third-party
contract manufacturers to manufacture and supply our preclinical and clinical
materials to be used during the development of our product candidates. We
currently do not need commercial manufacturing capacity.

Since we commenced operations, we have devoted substantially all of our resources to discovering, acquiring and developing product candidates, building our BBB platform technology and assembling our core capabilities in understanding key neurodegenerative disease pathways.

Key operational and financing milestones in 2020 to date include:



•In January 2020, we announced positive results from our LRRK2 program. Phase 1b
results with DNL201 in patients with Parkinson's disease demonstrated high
levels of target and pathway engagement and improvement of lysosomal biomarkers.
Interim Phase 1 results with DNL151 in more than 150 healthy volunteers also met
all safety and biomarker goals. Both clinical trials showed dose-dependent
target engagement, improvement in biomarkers of lysosomal function and
demonstrated safety profiles supporting progression to further development;
•In January 2020, we sold 9.0 million shares of common stock (inclusive of
shares sold pursuant to an overallotment option granted to the underwriters in
connection with the offering) through an underwritten public offering at a price
of $23.00 per share for aggregate net proceeds of $193.9 million;
•In February 2020, we initiated a Phase 1 clinical trial for DNL343 (EIF2B) in
healthy volunteers;
•In June 2020, we announced the results from Phase 1b clinical studies with
small molecule RIPK1 inhibitor DNL747 in Alzheimer's disease and ALS, and
provided a broad RIPK1 program update including CNS compound DNL788 and
peripherally-restricted compound DNL758. Safety endpoints were met in the Phase
1b patient studies with DNL747 in ALS and Alzheimer's disease, however further
dose escalation to achieve higher levels of target inhibition may be limited by
preclinical chronic safety data. As such, we announced, together with our
collaboration partner Sanofi, that we have decided to pause clinical studies
with DNL747 and focus our efforts on accelerating development of DNL788, which
we believe has superior drug properties and a more rapid path toward
proof-of-concept clinical studies in patients in multiple neurological
indications;
                                       35

•In July 2020, we announced that our collaboration partner Sanofi has commenced
dosing of DNL758, a peripherally-restricted small molecule inhibitor of RIPK1,
in a Phase 1b clinical study in hospitalized adult patients with severe COVID-19
lung disease. In October, we provided an update that enrollment in the Phase 1b
COVID-19 study is complete. Separately, Sanofi plans to initiate a Phase 2
clinical study of DNL758 in cutaneous lupus first half of 2021;

•In August 2020, we commenced dosing in a Phase 1/2 clinical study of DNL310 in Hunter syndrome patients. We plan to announce early biomarker data from the study by year end 2020;



•In August 2020, we entered into a binding Provisional Collaboration and License
Agreement with Biogen to co-develop and co-commercialize our small molecule
inhibitors of LRRK2 for Parkinson's disease. Under the Provisional Collaboration
and License Agreement, Biogen also received rights to opt into two programs and
a right of first negotiation for two additional programs, in each case for
neurodegenerative diseases leveraging our TV technology platform to cross the
BBB. In October 2020, the Provisional Collaboration and License Agreement
expired upon the execution of the Definitive LRRK2 Collaboration and License
Agreement and Right of First Negotiation, Option and License Agreement with
Biogen (collectively the "The Biogen Collaboration Agreement"). In connection
with the Biogen Collaboration Agreement, we received an equity investment of
$465.0 million in September 2020 and an aggregate of $560.0 million in upfront
payments in October 2020. We may be eligible to receive up to $1.1 billion in
potential milestone payments plus profit sharing and royalties for the LRRK2
program;

•In August 2020, we announced the selection of DNL151 to progress into late
stage clinical studies in Parkinson's disease patients with a kinase-activating
mutation in LRRK2 and in sporadic Parkinson's disease patients. Patient
enrollment is planned to commence in 2021 in collaboration with Biogen;

•In October 2020, our collaboration partner Sanofi submitted an IND application
for DNL788 (SAR443820), a potent, selective brain-penetrant small molecule
inhibitor of RIPK1. First-in-human dosing is planned to begin in late 2020 or
early 2021; and

•To address risks posed by the COVID-19 pandemic, we have implemented policies
that enable some of our employees to work remotely. For all on-site personnel,
we have implemented several safety protocols, including regular, mandatory
COVID-19 testing procedures and compliance measures for social distancing and
use of personal protective equipment. After initial COVID-19 pandemic shutdown
restrictions were put into place in March 2020, we experienced a pause in
patient recruitment in several clinical trials. Recruitment has since resumed
for all affected clinical trials.

We do not have any products approved for sale and have not generated any product
revenue since our inception. We have funded our operations primarily from the
issuance and sale of convertible preferred stock, and the proceeds from our
initial public offering ("IPO"), follow-on offering, and payments received from
our collaboration agreements with Takeda, Sanofi and Biogen.

We have incurred significant operating losses to date and expect to continue to
incur operating losses for the foreseeable future. Our ability to generate
product revenue will depend on the successful development and eventual
commercialization of one or more of our product candidates. Our net losses were
$58.2 million and $173.7 million for the three and nine months ended September
30, 2020, respectively, and $46.3 million and $143.6 million for the three and
nine months ended September 30, 2019, respectively. As of September 30, 2020, we
had an accumulated deficit of $599.3 million. We expect to continue to incur
significant expenses and operating losses as we advance our current clinical
stage programs through healthy volunteer and patient trials; broaden and improve
our BBB platform technology; acquire, discover, validate and develop additional
product candidates; obtain, maintain, protect and enforce our intellectual
property portfolio; and hire additional personnel.

Components of Operating Results
Collaboration Revenue

To date, we have not generated any revenue from product sales and do not expect
to generate any revenue from product sales for the foreseeable future. All
revenue recognized to date has been collaboration revenue from our collaboration
agreements with Takeda and Sanofi.

In the future, we will continue to recognize revenue from the Takeda
Collaboration Agreement and Sanofi Collaboration Agreement, and commence revenue
recognition from the Biogen Collaboration Agreement, and may generate revenue
from product sales or milestones, royalties and cost reimbursement from other
collaboration agreements, strategic alliances and licensing arrangements. We
expect that our revenue will fluctuate from quarter-to-quarter and year-to-year
as a result of the timing and amount of license fees, milestones, reimbursement
of costs incurred and other payments and product sales, to the extent any are
successfully commercialized. If we fail to complete the development of our
product candidates in a timely manner or obtain regulatory approval for them,
our ability to generate future revenue, and our results of operations and
financial position, would be materially adversely affected.

Operating Expenses

Research and Development



Research and development activities account for a significant portion of our
operating expenses. We record research and development expenses as incurred.
Research and development expenses incurred by us for the discovery and
development of our product candidates and BBB platform technology include:

•external research and development expenses, including:



-expenses incurred under arrangements with third parties, such as contract
research organizations ("CROs"), preclinical testing organizations, contract
development and manufacturing organizations ("CDMOs"), academic and non-profit
institutions and consultants;

-expenses to acquire technologies to be used in research and development that have not reached technological feasibility and have no alternative future use;

-fees related to our license and collaboration agreements;

•personnel related expenses, including salaries, benefits and stock-based compensation expense; and

•other expenses, which include direct and allocated expenses for laboratory, facilities and other costs.

A portion of our research and development expenses are direct external expenses, which we track on a program-specific basis once a program has commenced late-stage IND-enabling studies.



Program expenses include expenses associated with our most advanced product
candidates and the discovery and development of backup or next-generation
molecules. We also track external expenses associated with our TV platform.
These expenses include those incurred by us relating to our Takeda Collaboration
Agreement, Sanofi Collaboration Agreement and Biogen Collaboration Agreement.
All external costs associated with earlier stage programs, or that benefit the
entire portfolio, are tracked as a group. We do not track personnel or other
operating expenses incurred for our research and development programs on a
program-specific basis. These expenses primarily relate to salaries and
benefits, stock-based compensation, facility expenses including rent and
depreciation, and lab consumables.

It is challenging to predict the nature, timing and estimated long-range costs
of the efforts that will be necessary to complete the development of, and obtain
regulatory approval for, any of our product candidates. This is made more
challenging by events outside of our control, such as the recent COVID-19
pandemic. We are also unable to predict when, if ever, material net cash inflows
will commence from sales or licensing of our product candidates. This is due to
the numerous risks and uncertainties associated with drug development, including
the uncertainty of:

•our ability to add and retain key research and development personnel;

•our ability to establish an appropriate safety profile with IND-enabling toxicology studies;

•our ability to successfully develop, obtain regulatory approval for, and then successfully commercialize, our product candidates;

•our successful enrollment in and completion of clinical trials;

•the costs associated with the development of any additional product candidates we identify in-house or acquire through collaborations;

•our ability to discover, develop and utilize biomarkers to demonstrate target engagement, pathway engagement and the impact on disease progression of our molecules;

•our ability to establish agreements with third-party manufacturers for clinical supply for our clinical trials and commercial manufacturing, if our product candidates are approved;

•the terms and timing of any collaboration, license or other arrangement, including the terms and timing of any milestone payments thereunder;



•our ability to obtain and maintain patent, trade secret and other intellectual
property protection and regulatory exclusivity for our product candidates if and
when approved;

•our receipt of marketing approvals from applicable regulatory authorities;

•our ability to commercialize products, if and when approved, whether alone or in collaboration with others; and

•the continued acceptable safety profiles of the product candidates following approval.



A change in any of these variables with respect to the development of any of our
product candidates would significantly change the costs, timing and viability
associated with the development of that product candidate. We expect our
research and development expenses to increase at least over the next several
years as we continue to implement our business strategy, advance our current
programs, expand our research and development efforts, seek regulatory approvals
for any product candidates that successfully complete clinical trials, access
and develop additional product candidates and incur expenses associated with
hiring additional personnel to support our research and development efforts. In
addition, product candidates in later stages of clinical development generally
incur higher development costs than those in earlier stages of clinical
development, primarily due to the increased size and duration of later-stage
clinical trials.

  Table of Contents
General and Administrative

General and administrative expenses include personnel-related expenses, such as
salaries, benefits, travel and stock-based compensation expense, expenses for
outside professional services and allocated expenses. Outside professional
services consist of legal, accounting and audit services and other consulting
fees. Allocated expenses consist of rent, depreciation and other expenses
related to our office and research and development facility not otherwise
included in research and development expenses.

We expect to continue to incur certain expenses as a result of operating as a
public company, including expenses related to compliance with the rules and
regulations of the SEC and those of any national securities exchange on which
our securities are traded, insurance expenses, investor relations activities and
other administrative and professional services. We also expect to increase our
administrative headcount as we advance our product candidates through clinical
development, which will also increase our general and administrative expenses.

Interest and Other Income, Net

Interest and other income, net, consists primarily of interest income and investment income earned on our cash, cash equivalents, and marketable securities, gains and losses on foreign currency hedges, and sublease income.

Collaboration revenue

Collaboration revenue was $9.4 million and $18.8 million for the three and nine
months ended September 30, 2020, respectively, and $13.6 million and $22.0
million for the three and nine months ended September 30, 2019, respectively.
The decreases in collaboration revenue of $4.2 million and $3.2 million for the
three and nine months ended September 30, 2020, respectively, compared to the
comparative period in the prior year were due to a decrease in revenue from our
collaboration with Sanofi driven by a $10.0 million milestone recognized in the
three and nine months ended September 30, 2019 related to the Peripheral
program, and the winding down of revenue for retained activities as activities
are transferred to Sanofi. These decreases are partially offset by an increase
in revenue from our collaboration with Takeda, driven by increased costs
incurred in the programs partnered with Takeda.

__________________________________________________


(1)Personnel-related expenses include stock-based compensation expense of $7.8
million and $21.0 million for the three and nine months ended September 30,
2020, respectively, and $4.9 million and $14.2 million for the three and nine
months ended September 30, 2019, respectively, reflecting an increase of $2.9
million and $6.8 million, respectively.

There was an increase in total research and development expenses of $1.2 million
for the three months ended September 30, 2020 compared to the three months ended
September 30, 2019. This increase was a result of a $4.8 million increase in
personnel-related expenses, consisting of a $1.9 million increase in salaries
and related expenses attributable to an increase in our research and development
headcount, and a $2.9 million increase in stock-based compensation expense
primarily attributable to new equity award grants. Additionally, there were
increases in external expenses related to progression of our portfolio,
including an increase of $1.9 million in EIF2B program external expenses
reflecting the cost of the Phase 1 clinical trial, and an increase of $2.0
million in TV platform and other program external expenses. These increases were
partially offset by a $3.2 million decrease in other external research and
development expenses, primarily attributable to a decrease in DNL747 costs after
completion of the Phase 1b trials, a $2.4 million decrease in LRRK2 program
expenses, reflecting completion of DNL201 clinical activities, a $1.3 million
decrease in ETV:IDS program external expenses primarily due to significant CMC
activity in 2019, and a decrease in other unallocated research and development
expenses of $0.6 million primarily attributable to decreased lab consumables
costs and reductions in associated expenses related to COVID-19.

There was an increase in total research and development expenses of $16.0
million for the nine months ended September 30, 2020 compared to the nine months
ended September 30, 2019. This increase was a result of a $14.9 million increase
in personnel-related expenses, consisting of a $8.1 million increase in salaries
and related expenses attributable to an increase in our research and development
headcount, and a $6.8 million increase in stock-based compensation expense
primarily attributable to new equity award grants. Additionally, there were
increases in external expenses related to progression of our portfolio,
including an increase of $3.0 million in EIF2B program external expenses
reflecting the cost of the Phase 1 clinical trial, an increase of $0.9 million
in TV platform and other program external expenses, an increase of $0.7 million
in LRRK2 program external expenses driven by DNL151 progress in the clinic, and
an increase in other unallocated research and development expenses of $0.1
million. These increases were partially offset by a decrease of $0.9 million in
ETV:IDS program external expenses due to the $1.5 million contingent
consideration payment to F-star and significant CMC activity, both in 2019, and
a $2.7 million decrease in other external research and development expenses,
primarily attributable to a decrease in DNL747 costs after completion of the
Phase 1b trials.

General and administrative expenses

General and administrative expenses were $15.8 million for the three months
ended September 30, 2020 compared to $11.2 million for the three months ended
September 30, 2019. The increase of approximately $4.6 million was primarily
attributable to a $2.0 million increase in personnel-related expenses, primarily
driven by higher stock-based compensation expense in the three months ended
September 30, 2019 primarily attributable to new equity award grants.
Additionally, there was an increase of $2.0 million in professional services
costs, primarily due to costs associated with the execution of the Biogen
Collaboration Agreement, an increase of $0.5 million in other general and
administrative costs related to other miscellaneous costs such as insurance and
taxes, and a $0.1 million increase in facilities-related expenses.

General and administrative expenses were $42.3 million for the nine months ended
September 30, 2020 compared to $35.6 million for the nine months ended September
30, 2019. The increase of approximately $6.7 million was primarily attributable
to increases of $3.0 million in personnel-related expenses primarily driven by
higher headcount, $2.8 million in professional services costs, primarily due to
costs associated with the execution of the Biogen Collaboration Agreement, $0.6
million in other general and administrative costs related to other miscellaneous
costs such as insurance and taxes, and $0.3 million in facilities-related
expenses.

Interest and other income, net



Interest and other income, net was $1.9 million for the three months ended
September 30, 2020 compared to $3.8 million for the three months ended September
30, 2019. The decrease of $1.9 million was primarily due to decreased interest
income earned on our investments due to declining interest rates.

Interest and other income, net was $7.6 million for the nine months ended
September 30, 2020 compared to $11.4 million for the nine months ended September
30, 2019. The decrease of $3.8 million was primarily due to a $5.0 million
decrease in interest income earned on our investments due to declining interest
rates, partially offset by an increase of $1.2 million in sublease income and
reimbursements received in the nine months ended September 30, 2020 compared to
the nine months ended September 30, 2019.

Income tax benefit (provision)
Income tax provision associated with a decrease in unrealized gains on
marketable securities in other comprehensive income was $0.1 million for the
three months ended September 30, 2020 compared to an income tax benefit of $0.1
million for the three months ended September 30, 2019 associated with unrealized
gains on marketable securities in other comprehensive income.

There was no income tax benefit associated with an unrealized gain on marketable
securities in other comprehensive income for the nine months ended September 30,
2020 compared to $0.4 million for the nine months ended September 30, 2019.

Liquidity and Capital Resources
Sources of Liquidity

We fund our operations primarily with the proceeds from our IPO, our follow-on
offering, and payments received from our collaboration agreements with Takeda,
Sanofi, and Biogen. We received net proceeds of $264.3 million from our IPO in
December 2017. In January 2020, we sold 9.0 million shares of common stock
(inclusive of shares sold pursuant to an overallotment option granted to the
underwriters in connection with the offering) through an underwritten public
offering at a price of $23.00 per share for aggregate net proceeds of $193.9
million.

Pursuant to the Takeda Collaboration Agreement, we have received $55.0 million
related to upfront and milestone payments through September 30, 2020. Further,
under the associated Stock Purchase Agreement we received $110.0 million in
February 2018 for the sale and issuance of 4,214,559 shares of our common stock.

Pursuant to the Sanofi Collaboration Agreement, we have received $135.0 million
related to upfront and milestone payments, and further payments of $11.2 million
for performance of Retained Activities through September 30, 2020.

Pursuant to the common stock purchase agreement between Denali and Biogen (the
"Biogen Stock Purchase Agreement"), we received $465.0 million in September 2020
for the sale and issuance of 13,310,243 shares of our common stock. In October
2020, we received $560.0 million from Biogen in upfront payments associated with
the Biogen Collaboration Agreement.

As of September 30, 2020, we had cash, cash equivalents and marketable securities in the amount of $981.5 million. Future Funding Requirements



To date, we have not generated any product revenue. We do not expect to generate
any product revenue unless and until we obtain regulatory approval of and
commercialize any of our product candidates, and we do not know when, or if,
either will occur.

We expect to continue to incur significant losses for the foreseeable future,
and we expect the losses to increase as we expand our research and development
activities and continue the development of, and seek regulatory approvals for,
our product candidates, and begin to commercialize any approved products.
Further, we expect general and administrative expenses to increase as we
continue to incur additional costs associated with supporting our growing
operations. We are subject to all of the risks typically related to the
development of new product candidates, and we may encounter unforeseen expenses,
difficulties, complications, delays and other unknown factors that may adversely
affect our business. We anticipate that we will need substantial additional
funding in connection with our continuing operations.

                                       43

Until we can generate a sufficient amount of revenue from the commercialization
of our product candidates or from our existing collaboration agreements, or
future agreements with other third parties, if ever, we expect to finance our
future cash needs through public or private equity or debt financings.
Additional capital may not be available on reasonable terms, if at all. If we
are unable to raise additional capital in sufficient amounts or on terms
acceptable to us, we may have to significantly delay, scale back or discontinue
the development or commercialization of one or more of our product candidates.
If we raise additional funds through the issuance of additional debt or equity
securities, it could result in dilution to our existing stockholders, increased
fixed payment obligations and the existence of securities with rights that may
be senior to those of our common stock. If we incur indebtedness, we could
become subject to covenants that would restrict our operations and potentially
impair our competitiveness, such as limitations on our ability to incur
additional debt, limitations on our ability to acquire, sell or license
intellectual property rights and other operating restrictions that could
adversely impact our ability to conduct our business. Additionally, any future
collaborations we enter into with third parties may provide capital in the near
term but limit our potential cash flow and revenue in the future. Any of the
foregoing could significantly harm our business, financial condition and
prospects.

Since our inception, we have incurred significant losses and negative cash flows
from operations. We have an accumulated deficit of $599.3 million through
September 30, 2020. We expect to incur substantial additional losses in the
future as we conduct and expand our research and development activities. We
believe that our existing cash, cash equivalents and marketable securities will
be sufficient to enable us to fund our projected operations through at least 12
months from the filling date of this Form 10-Q. We have based this estimate on
assumptions that may prove to be wrong, and we could utilize our available
capital resources sooner than we currently expect. Our future funding
requirements will depend on many factors, including:

•the timing and progress of preclinical and clinical development activities;

•the number and scope of preclinical and clinical programs we decide to pursue;

•the progress of the development efforts of third parties with whom we have entered into license and collaboration agreements;

•our ability to maintain our current research and development programs and to establish new research and development, license or collaboration arrangements;

•our ability and success in securing manufacturing relationships with third parties or, in the future, in establishing and operating a manufacturing facility;

•the costs involved in prosecuting, defending and enforcing patent claims and other intellectual property claims;

•the cost and timing of regulatory approvals;

•our efforts to enhance operational, financial and information management systems and hire additional personnel, including personnel to support development of our product candidates; and

•the costs and ongoing investments to in-license and/or acquire additional technologies.



A change in the outcome of any of these or other variables with respect to the
development of any of our product candidates could significantly change the
costs and timing associated with the development of that product candidate.
Furthermore, our operating plans may change in the future, and we may need
additional funds to meet operational needs and capital requirements associated
with such operating plans.

Net Cash Used In Operating Activities



During the nine months ended September 30, 2020, cash used in operating
activities was $97.8 million, which consisted of a net loss of $173.7 million,
adjusted by non-cash items primarily related to stock-based compensation and
depreciation, partially offset by net amortization of discounts on marketable
securities and non-cash rent expenses. Cash used in operating activities was
also driven by changes in our operating assets and liabilities, including an
increase in related party contract liability associated with the Biogen
Collaboration Agreement.

Net Cash Provided By (Used In) Investing Activities



During the nine months ended September 30, 2020, cash used in investing
activities was $255.9 million, which consisted of $687.5 million of purchases of
marketable securities and $1.9 million of capital expenditures to purchase
property and equipment, partially offset by $433.6 million in proceeds from the
maturity of marketable securities.

Net Cash Provided By Financing Activities



During the nine months ended September 30, 2020, cash provided by financing
activities was $625.2 million, which consisted of $420.1 million associated with
the issuance of 13,310,243 shares of our common stock to Biogen in September
2020 under the Biogen Stock Purchase Agreement, $193.9 million in net cash
proceeds from our follow-on offering completed in January 2020, and $11.1
million in proceeds from the exercise of options to purchase common stock and
issuance of ESPP shares.

Contractual Obligations and Commitments

In May 2018, we entered into an amendment to our operating lease for our former
corporate headquarters in South San Francisco (the "Headquarters Lease
Amendment") to relocate and expand our headquarters to 148,020 rentable square
feet in a building in South San Francisco, California (the "New Premises"). The
Headquarters Lease Amendment has a contractual term of ten years from the legal
commencement date, which was April 1, 2019 when the building was ready for
occupancy. For accounting purposes, the lease commencement date was determined
to be August 1, 2018, which was the date at which we were deemed to have
obtained control over the property. We have an option to extend the lease term
for a period of ten years by giving the landlord written notice of the election
to exercise the option at least nine months, but not more than twelve months,
prior to the expiration of the Headquarters Lease Amendment lease term. We
determined that this renewal was not reasonably certain at lease inception.

The Headquarters Lease Amendment provides for monthly base rent amounts
escalating over the term of the lease. In addition, the Headquarters Lease
Amendment provided a tenant improvement allowance ("TIA") of up to $25.9
million, which was fully utilized, of which $4.4 million will be repaid to the
landlord in the form of additional monthly rent. This is recorded as leasehold
improvement assets and an offset to the lease ROU asset on the Consolidated
Balance Sheets as of September 30, 2020 and December 31, 2019. We are also
required to pay the operating expenses for the New Premises, such as taxes and
insurance, which are treated as variable lease payments.

Effective September 2017, we entered into a Development and Manufacturing
Services Agreement, as amended ("DMSA") with Lonza Sales AG ("Lonza") for the
development and manufacture of biologic products. Under the DMSA, we will
execute purchase orders based on project plans authorizing Lonza to provide
development and manufacturing services with respect to certain of our antibody
and enzyme products, and will pay for the services provided and batches
delivered in accordance with the DMSA and project plan. Unless earlier
terminated, the DMSA will expire on September 6, 2022.

As of September 30, 2020 and December 31, 2019, we had open non-cancellable
purchase orders for biological product development and manufacturing costs
totaling $17.6 million and $21.2 million, respectively. The activities under
these purchase orders are expected to be completed by May 2027. As of September
30, 2020 and December 31, 2019, we had total non-cancellable purchase
commitments, under the DMSA of $12.0 million and $11.2 million, respectively.

During the three months ended September 30, 2020 and 2019, we incurred costs of
$1.4 million and $3.0 million, respectively, and made payments of $0.8 million
and $2.5 million, respectively, for the development and manufacturing services
rendered under the DMSA. During the nine months ended September 30, 2020 and
2019, we incurred costs of $6.2 million and $9.7 million, respectively, and made
payments of $6.0 million and $9.0 million, respectively, for the development and
manufacturing services rendered under the DMSA.

Other than those detailed above, there have been no other material changes from
the contractual obligations and commitments previously disclosed in our Annual
Report on Form 10-K for the year ended December 31, 2019, as filed with the SEC
on February 27, 2020.

Critical Accounting Policies and Significant Judgments and Estimates

This discussion and analysis of our financial condition and results of
operations is based on our condensed consolidated financial statements, which
have been prepared in accordance with U.S. GAAP. The preparation of these
condensed consolidated financial statements requires us to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the condensed
consolidated financial statements, as well as the reported revenues recognized
and expenses incurred during the reporting periods. Our estimates are based on
our historical experience and on various other factors that we believe are
reasonable under the circumstances, the results of which form the basis for
making judgments about the carrying value of assets and liabilities that are not
readily apparent from other sources. Actual results may differ from these
estimates under different assumptions or conditions.

There have been no material changes to our critical accounting policies and
estimates during the nine months ended September 30, 2020 from those described
in "Management's Discussion and Analysis of Financial Condition and Results of
Operations" included in our Annual Report on Form 10-K for the year ended
December 31, 2019, as filed with the SEC on February 27, 2020.
Recent Accounting Pronouncements

Except as described in Note 1 to the condensed consolidated financial statements
under the headings "Recently Issued Accounting Pronouncement" and "Recently
Adopted Accounting Pronouncement," there have been no new accounting
pronouncements or changes to accounting pronouncements during the nine months
ended September 30, 2020, as compared to the recent accounting pronouncements
described in our Annual Report on Form 10-K for the year ended December 31,
2019, as filed with the SEC on February 27, 2020, that are of significance or
potential significance to us.
