The following discussion of our financial condition and results of operations
should be read in conjunction with our condensed consolidated financial
statements and notes thereto appearing elsewhere in this Quarterly Report on
Form 10-Q and the audited consolidated financial statements and notes thereto
included in our Annual Report on Form 10-K for the year ended December 31, 2019.

This discussion contains forward-looking statements that involve significant
risks and uncertainties. As a result of many important factors, such as those
set forth under "Risk Factors" in Part II., Item 1A. of this Quarterly Report on
Form 10-Q, our actual results may differ materially from those anticipated in
these forward-looking statements.



                                    Overview

We are a biotechnology company focused on the discovery and development of novel
biologic therapies for the treatment of rare immune-mediated diseases.
Prior to 2018, we had the dual focus of developing novel drug candidates and
nurturing a portfolio of biosimilar and complex generic products and product
candidates. In the beginning of 2018, we engaged in a strategic review of our
business and made the decision that shareholder value could be enhanced by
shifting our future investments to fully support our promising novel drug
portfolio. Following this strategic review, we made the decision in September
2018 to restructure the company.
While we have terminated all future development of any new or early stage
biosimilar and complex generic products, we have retained our commercial
partnership with Sandoz AG, or Sandoz, for our generic versions of COPAXONE and
LOVENOX, which are approved products. We believe that Sandoz's sales of GLATOPA,
our generic version of COPAXONE, can generate cash flow to help fund our novel
pipeline. Enoxaparin Sodium Injection, our generic version of LOVENOX, is not
currently marketed by Sandoz. In addition, we are developing an EYLEA
biosimilar, in collaboration with Mylan Ireland Limited, or Mylan, a
wholly-owned indirect subsidiary of Mylan N.V., which is currently conducting a
clinical trial in patients. If the results from this study are supportive, we
believe this program has the potential to launch in the 2023 time frame and help
fund our novel portfolio.
To date, we have devoted substantially all of our capital resource expenditures
to the research and development of our product candidates. Although we were
profitable in fiscal years 2010 and 2011, since that time we have been incurring
operating losses and we expect to incur annual operating losses over the next
several years as we advance our drug development portfolio. As of June 30, 2020,
we had an accumulated deficit of approximately $1.1 billion. We will need to
generate significant revenue to return to profitability. We expect that our
return to profitability, if at all, will most likely come from the
commercialization of the products in our drug development portfolio.
Novel Therapeutics
We believe our novel product candidates could be capable of treating a large
number of immune-mediated disorders whose pathogenesis is driven in whole or in
part by autoantibodies, immune complexes, and Fc receptor biology.
M281 (Nipocalimab) - Anti-FcRn Candidate
M281 is a fully-human anti-neonatal Fc receptor, or anti FcRn, aglycosylated
immunoglobulin G, or IgG1, monoclonal antibody, engineered to reduce circulating
IgG antibodies, by completely blocking endogenous IgG recycling via FcRn.
A Phase 1 randomized, double-blind, placebo-controlled study to evaluate the
safety, tolerability, pharmacokinetics and pharmacodynamics of M281 in 114
normal healthy volunteers was initiated in June 2016. The full results of the
Phase 1 study were published on November 7, 2018. A total of 50 patients were
enrolled in both the single ascending dose and multiple ascending dose portions
of the study, both of which showed predictable pharmacokinetics, and
commensurate, controllable and reproducible reductions in circulating IgG. The
data showed M281 could achieve a full receptor occupancy with a single dose and
a greater than 80% reduction in circulating IgG antibodies, with a mean
reduction of 84%. M281 was well tolerated at all dose levels and no serious
adverse events or unexpected safety findings were observed in either portion of
the study.
In the fourth quarter of 2018, we commenced Vivacity-MG, our Phase 2
proof-of-concept clinical trial for the treatment of patients with generalized
myasthenia gravis, or gMG, who have insufficient clinical response to the
standard-of-care treatment.
                                       26

  Table of Contents
Also in the fourth quarter of 2018, we commenced Unity, our Phase 2
proof-of-concept clinical trial for the treatment of women at high risk for
early onset hemolytic disease of the fetus and newborn, or HDFN. In the third
quarter of 2019, we commenced Energy Study, our Phase 2/3 clinical trial in warm
autoimmune hemolytic anemia, or wAIHA. In July 2019, the Food and Drug
Administration, or FDA, granted Fast Track designation for our HDFN and wAIHA
indications, which is a process designed to facilitate the development and
expedite the review of drugs to treat serious conditions and fill unmet medical
need. In July 2020, we announced that the FDA granted Rare Pediatric Disease and
Orphan Drug designations for our HDFN indication.
M254 - Hyper-sialylated IgG Candidate
M254 is a hyper-sialylated immunoglobulin designed as a high potency alternative
to IVIg, a therapeutic drug product that contains pooled, human immunoglobulin
G, or IgG, antibodies purified from blood plasma. IVIg is used to treat many
inflammatory diseases, including idiopathic thrombocytopenic purpura, or ITP,
and chronic inflammatory demyelinating polyneuropathy, or CIDP. In nonclinical
studies, M254 has been shown to have up to ten times more enhanced
anti-inflammatory activity than IVIg in a variety of animal models of autoimmune
disease.
We initiated a multi-part Phase 1/2 proof of concept clinical study in normal,
healthy volunteers and patients with ITP in early 2019.
M230 (CSL730) - Recombinant Fc Multimer Candidate
M230 is a novel recombinant trivalent human IgG1 Fc multimer containing three
IgG Fc regions joined to maximize activity. Nonclinical data have shown that
M230 has enhanced avidity for the Fc receptors, matching the potency and
efficacy of IVIg at significantly lower doses.
Pursuant to the License and Option Agreement, effective February 17, 2017, with
CSL Behring Recombinant Facility AG, or CSL, a wholly-owned indirect subsidiary
of CSL Limited, we granted CSL an exclusive worldwide license to research,
develop, manufacture and commercialize M230. In August 2017, we exercised our
50% co-funding option, which is discussed further in Note 8, "License Agreements
and Collaborative Arrangements" to our condensed consolidated financial
statements.
CSL's Phase 1 clinical study in healthy volunteers to evaluate the safety and
tolerability of M230 is continuing and CSL anticipates introducing a
subcutaneous formulation into the Phase 1 clinical study in 2020.
Legacy Products
M710-Biosimilar EYLEA® (aflibercept) Candidate
M710 is being developed as a biosimilar of EYLEA in collaboration with Mylan. In
August 2018, Mylan initiated dosing of patients in the United States in our
pivotal clinical trial. In December 2018 and February 2019, Mylan initiated
dosing of patients in the European Union and Japan, respectively. This trial is
a randomized, double-blind, active-control, multi-center study in patients with
diabetic macular edema to compare the safety, efficacy and immunogenicity of
M710 to EYLEA. Subject to development, marketing approval, patent considerations
and litigation timelines, we expect U.S. market formation for biosimilar
versions of EYLEA to be in the 2023 time frame.
GLATOPA® (glatiramer acetate injection) 20 mg/mL-Generic Once-daily COPAXONE®
(glatiramer acetate injection) 20 mg/mL
In April 2015, the FDA approved the ANDA for GLATOPA 20 mg/mL, a generic
equivalent of once-daily COPAXONE 20 mg/mL. GLATOPA 20 mg/mL was the first "AP"
rated, substitutable generic equivalent of once-daily COPAXONE. Sandoz commenced
sales of GLATOPA 20 mg/mL in June 2015. Under our collaboration agreement with
Sandoz, we earn 50% of contractually defined profits on GLATOPA 20 mg/mL
worldwide net sales.
In October 2017, Mylan N.V. announced the launch of its generic equivalents of
once-daily COPAXONE 20 mg/mL and three-times-weekly COPAXONE 40 mg/mL. Following
Mylan N.V.'s entry into the market, Sandoz has defended GLATOPA's share of the
20 mg/mL glatiramer acetate injection market by using one or more contracting
strategies, including but not limited to, lowering its GLATOPA 20 mg/mL price or
increasing the discounts or rebates it offers for GLATOPA 20 mg/mL, which has
decreased contractual profit share revenue. We estimate that the number of
prescriptions for GLATOPA 20 mg/mL currently represents approximately 36% of the
once-daily 20 mg/mL U.S. glatiramer acetate market.
                                       27

GLATOPA® (glatiramer acetate injection) 40 mg/mL-Generic Three-times-weekly COPAXONE® (glatiramer acetate injection) 40 mg/mL

In February 2018, we announced that GLATOPA 40 mg/mL, a generic version of three-times-weekly COPAXONE 40 mg/mL, was approved by the FDA and launched by our collaborator, Sandoz.



Since Sandoz's launch of GLATOPA 40mg/mL in February 2018, we believe Sandoz has
encountered aggressive pricing and contracting tactics from competitors, which
has limited uptake of the product and as a result we expect modest revenues for
this product in the future. As of June 30, 2020, 40 mg/mL glatiramer acetate
injection accounted for approximately 85% of the overall U.S. glatiramer acetate
injection market (20 mg/mL and 40 mg/mL) based on volume prescribed.

GLATOPA refers to GLATOPA 20 mg/mL and GLATOPA 40 mg/mL, collectively.

Enoxaparin Sodium Injection-Generic LOVENOX®



Under the 2003 Sandoz Agreement, Sandoz is obligated to pay us 50% of
contractually defined profits on sales of Enoxaparin Sodium Injection. In July
2018, Sandoz notified its customers and the FDA that it will discontinue
supplying Enoxaparin Sodium Injection. Sandoz continues to evaluate alternate
acceptable contract manufacturers at a price point that will allow for
profitable and competitive sales and may decide to relaunch Enoxaparin Sodium
Injection at a later date following regulatory approval. We expect future
revenues from Sandoz' sales of Enoxaparin Sodium Injection, if any, to be
minimal. On July 10, 2020 we and Sandoz entered into an agreement pursuant to
which we will (i) transfer all of our right, title and interest in the
Enoxaparin product to Sandoz and (ii) terminate the 2003 Sandoz Agreement as
described under Note 12, "Subsequent Events" to our condensed consolidated
financial statements.

Legal proceedings related to Enoxaparin Sodium Injection are described under
Note 11, "Commitments and Contingencies" to our condensed consolidated financial
statements.

Impact of COVID-19
We are closely monitoring how the spread of the novel coronavirus, COVID-19, is
affecting our employees, business, preclinical studies and clinical trials. In
response to the spread of COVID-19, our employees are working remotely, and we
have suspended all business travel. In April 2020, we announced that we have
temporarily suspended patient enrollment in our Energy Study, an adaptive Phase
2/3 clinical study of nipocalimab in wAIHA. We also announced that we expect to
launch our Phase 2 study of M254 in CIDP in 2021, as opposed to the fourth
quarter of 2020, as previously disclosed.

Disruptions caused by the COVID-19 pandemic may result in further difficulties
or delays in initiating, enrolling, conducting or completing our planned and
ongoing clinical trials and the incurrence of unforeseen costs as a result of
preclinical study or clinical trial delays. As a result, we expect that the
COVID-19 pandemic may impact our business, revenues, results of operations and
financial condition. At this time, there is significant uncertainty relating to
the trajectory of the COVID-19 pandemic and impact of related responses. The
impact of COVID-19 on our future results will largely depend on future
developments, which are highly uncertain and cannot be predicted with
confidence, such as the ultimate geographic spread of the disease, the duration
of the pandemic, the ultimate impact of the pandemic on financial markets and
the global economy, travel restrictions and social distancing in the United
States and other countries, business closures or business disruptions and the
effectiveness of actions taken in the United States and other countries to
contain and treat the disease. See Risk Factors, "The outbreak of the novel
coronavirus disease, COVID-19, could adversely impact our business, including
our preclinical studies and clinical trials." in Part II, Item 1A of this
Quarterly Report on Form 10-Q.

Product Revenue
Sandoz commenced sales of GLATOPA 20 mg/mL in the United States in June 2015 and
GLATOPA 40 mg/mL in February 2018. We earn 50% of contractually defined profits
on Sandoz' worldwide net sales of GLATOPA.
We estimate that the number of prescriptions for GLATOPA 20 mg/mL represented
approximately 36% of the once-daily 20 mg/mL U.S. glatiramer acetate market as
of June 30, 2020.
Since Sandoz' launch of GLATOPA 40mg/mL in February 2018, we believe Sandoz has
encountered aggressive pricing and contracting tactics from competitors, which
has limited uptake of the product, and, as a result, we expect modest sales for
the product in the future. As of June 30, 2020, 40 mg/mL glatiramer acetate
injection accounted for approximately 85% of the overall U.S. glatiramer acetate
injection market (20 mg/mL and 40 mg/mL) based on volume prescribed.
The increase in product revenue of $3.3 million, or 98%, from the three months
ended June 30, 2019 to the three months ended June 30, 2020 was due to higher
net sales of GLATOPA.

Research and Development Revenue



Research and development revenue generally consists of amounts earned by us
under our collaborations for technical development, regulatory and commercial
milestones, reimbursement of research and development services and reimbursement
of development costs under our collaborative arrangements, and recognition of
upfront arrangement consideration.

We expect to recognize revenue from the remaining balance of $1.6 million from Mylan's $45.0 million upfront payment on a quarterly basis in an amount commensurate with our progress towards meeting performance obligations with respect to M710 under the Mylan Collaboration Agreement.



The decrease in research and development revenue of $1.8 million, or 99%, from
the three months ended June 30, 2019 to the three months ended June 30, 2020 was
due to lower reimbursement revenue for GLATOPA expenses and lower revenue
recognized from Mylan's upfront payment due to the partial termination of the
Mylan Collaboration Agreement.

Research and Development Expense



Research and development expenses consist of costs incurred to conduct research,
such as the discovery and development of our product candidates. We recognize
all research and development costs as they are incurred. We track the external
research and development costs incurred for each of our product candidates. Our
external research and development expenses consist primarily of:
•expenses incurred under agreements with consultants, third-party contract
research organizations, or CROs, and investigative sites where all of our
nonclinical studies and clinical trials are conducted;
•costs of manufacturing clinical trial material, acquiring reference comparator
materials and manufacturing nonclinical study supplies and other materials from
contract manufacturing organizations, or CMOs, and related costs associated with
release and stability testing; and
•costs associated with process development activities.
Internal research and development costs are associated with activities performed
by our research and development organization and consist primarily of:
•personnel-related expenses, which include salaries, benefits and share-based
compensation; and
•facilities and other allocated expenses, which include direct and allocated
expenses for rent and maintenance of facilities, depreciation and amortization
of leasehold improvements and equipment and laboratory and other supplies.
For our collaboration arrangements in which the parties share in collaboration
expenses for products under the arrangement (cost sharing arrangements), we
record the reimbursement by the collaborator for its share of the development
effort as a reduction of research and development expense. Our share of costs
incurred by collaborators is recorded as research and development expense.
The lengthy process of securing FDA approval for new drugs, generics and
biosimilars requires the expenditure of substantial resources. Any failure by us
to obtain, or any delay in obtaining, regulatory approvals would materially
adversely affect our product development efforts and our business overall.
Accordingly, we cannot currently estimate with any degree of certainty the
amount of time or money that we will be required to expend in the future on our
product candidates prior to their regulatory approval, if such approval is ever
granted. As a result of these uncertainties surrounding the timing and outcome
of any approvals, we are currently unable to estimate when, if ever, our product
candidates will generate revenues and cash flows.

  Table of Contents
The following table sets forth the primary components of our research and
development external expenditures, including the amortization of our intangible
assets, for each of our principal development programs for the three months
ended June 30, 2020 and 2019. The figures in the table include project
expenditures incurred by us and reimbursed by our collaborators, but exclude
project expenditures incurred by our collaborators. Although we track and
accumulate personnel effort by percentage of time spent on our programs, a
significant portion of our internal research and development costs, including
salaries and benefits, share-based compensation, facilities, depreciation and
laboratory supplies are not directly charged to programs. Therefore, our methods
for accounting for internal research and development costs preclude us from
reporting these costs on a project-by-project basis.

that we commenced an additional Phase 2/3 clinical trial; M230, for which our
licensee's, CSL's, Phase 1 study in healthy volunteers to evaluate safety and
tolerability of M230 is ongoing; M254, for which we have initiated a Phase 1/2
clinical study in early 2019; as well as other discovery and nonclinical stage
programs.
(2)Biosimilars include M710, a biosimilar candidate of EYLEA® (aflibercept).
Mylan initiated a pivotal clinical trial in patients in the United States in
August 2018, and in December 2018 and February 2019, initiated dosing of
patients in the European Union and Japan, respectively. In November 2018, we
provided notice to Mylan terminating our participation in the development of our
biosimilar programs other than M710.
(3)Includes external costs for GLATOPA and Enoxaparin Sodium Injection. In July
2010, the first ANDA for Enoxaparin Sodium Injection was approved by the FDA,
and Sandoz launched the product. In April 2015, the FDA approved the ANDA for
once-daily GLATOPA 20 mg/mL. Sandoz launched GLATOPA 20 mg/mL in June 2015. In
February 2018, the FDA approved the ANDA for three-times-weekly GLATOPA 40
mg/mL, and Sandoz launched the product. For more information on GLATOPA, see
"Legacy Products" section above.
We expect research and development expense to increase for the foreseeable
future as our current development programs progress and new programs are added.
External costs of our novel therapeutic programs increased by $3.6 million, or
22%, from the three months ended June 30, 2019 to the three months ended June
30, 2020, and were primarily driven by an increase in manufacturing and clinical
trial activity for M254 as described in Note 1 in the above table, partially
offset by a decrease in our share of CSL collaboration costs for M230. External
expenditures for our biosimilars programs decreased by $2.0 million, or 46%,
from the three months ended June 30, 2019 to the three months ended June 30,
2020, primarily due to a decrease in spending on M710 and M923. Internal costs
increased by $5.2 million, or 44%, from the three months ended June 30, 2019 to
the three months ended June 30, 2020 primarily due to an increase in share-based
compensation expense related to PSUs, partially offset by a reduction in lease
costs.
General and Administrative
General and administrative expenses consist primarily of salaries, share-based
compensation and other related costs for personnel in general and administrative
functions, professional fees for legal and accounting services, legal
settlements, insurance costs, and allocated rent, facility and lab supplies, and
depreciation expense.
For our collaboration arrangements in which the parties share in collaboration
expenses for products under the arrangement (cost sharing arrangements), we
record the reimbursement by the collaborator for its share of the development
effort as a reduction of general and administrative expense. Our share of costs
incurred by collaborators is recorded as general and administrative expense.

We expect our general and administrative expenses, including internal and
external legal and business development costs that support our various product
development efforts, to vary from period to period in relation to our
commercial, litigation and development activities.
The decrease of $21.3 million, or 46%, from the three months ended June 30, 2019
to the three months ended June 30, 2020 was primarily due to a payment of $21.0
million to Amphastar in June 2019 reflecting our portion of the settlement
payment; lower legal fees and lower depreciation and rent costs due to the
modification to the Bent lease in 2019; partially offset by an increase in
share-based compensation expense related to PSUs.
Other Operating Expense
Other operating expense for the three months ended June 30, 2020 included a $0.2
million adjustment due to changes in the estimated fair value of the future
contractual obligations under our manufacturing services agreement with Human
Genome Sciences, Inc., or GSK. Other operating expense was $42.9 million for the
three months ended June 30, 2019 and included a take-or-pay purchase obligation
under our manufacturing agreement with GSK. Consistent with our decision to
cease active development of M923, we canceled our manufacturing runs scheduled
through 2020 and recorded a charge of $20.9 million in the three months ended
June 30, 2019, representing the minimum purchase obligation. Since the utility
of the remaining minimum purchase commitments for the calendar years 2021
through 2022 was deemed impaired at June 30, 2019, we recorded an additional
charge of $22.0 million during the six months ended June 30, 2019.

Restructuring

Restructuring charges consist of severance, bonus, share-based compensation, and impairment of equipment associated with our workforce reduction in October 2018.

Other Income, Net



Other income, net includes other items of non-operating income and expense.
Other income, net was $0.3 million and $2.7 million for the three months ended
June 30, 2020 and 2019, respectively. The decrease of $2.4 million, or 89%, from
the three months ended June 30, 2019 to the three months ended June 30, 2020 was
primarily the result of interest expense recognized on the purchase commitments
under our manufacturing agreement with GSK and lower interest income due to
lower market yields on our investments.

Comparison of Six Months Ended June 30, 2020 and 2019

Product revenue includes our contractually defined profits earned on Sandoz' sales of GLATOPA.

Product Revenue
The increase in product revenue of $9.6 million, or 169%, from the six months
ended June 30, 2019 to the six months ended June 30, 2020 was due to higher net
sales of GLATOPA.

Research and Development Revenue



The decrease in research and development revenue of $3.4 million, or 94%, from
the six months ended June 30, 2019 to the six months ended June 30, 2020 was due
to lower reimbursement revenue for GLATOPA expenses and lower revenue recognized
from Mylan's upfront payment due to the partial termination of the Mylan
Collaboration Agreement.

Research and Development Expense
The following table sets forth the primary components of our research and
development external expenditures, including the amortization of our intangible
assets, for each of our principal development programs for the six months ended
June 30, 2020 and 2019. The figures in the table include project expenditures
incurred by us and reimbursed by our collaborators, but exclude project
expenditures incurred by our collaborators. Although we track and accumulate
personnel effort by percentage of time spent on our programs, a significant
portion of our internal research and development costs, including salaries and
benefits, share-based compensation, facilities, depreciation and laboratory
supplies are not directly charged to programs. Therefore, our methods for
accounting for internal research and development costs preclude us from
reporting these costs on a project-by-project basis.

"Legacy Products" section above.
We expect research and development expense to increase for the foreseeable
future as our current development programs progress and new programs are added.
External costs of our novel therapeutic programs increased by $8.6 million, or
30%, from the six months ended June 30, 2019 to the six months ended June 30,
2020, and were primarily driven by an increase in manufacturing and clinical
trial activity for M254 and M281 as described in Note 1 in the above table,
partially offset by a decrease in our share of CSL collaboration costs for M230.
External expenditures for our biosimilars programs increased by $0.1 million, or
2%, from the six months ended June 30, 2019 to the six months ended June 30,
2020, primarily due to an increase in spending on M710, partially offset by a
reduction in M923 costs. Internal costs increased by $4.4 million, or 18%, from
the six months ended June 30, 2019 to the six months ended June 30, 2020
primarily due to an increase in share-based compensation expense related to
PSUs, partially offset by a reduction in lease costs.
General and Administrative
The decrease of $30.9 million, or 44%, from the six months ended June 30, 2019
to the six months ended June 30, 2020 was primarily due to a payment of $21.0
million to Amphastar in June 2019 reflecting our portion of the settlement
payment; lower legal fees and lower depreciation and rent costs due to the
modification to the Bent lease in 2019; partially offset by an increase in
share-based compensation expense related to PSUs.
Other Operating Expense
Other operating expense for the six months ended June 30, 2020 included a $0.6
million adjustment due to changes in the estimated fair value of the future
contractual obligations under our manufacturing services agreement with Human
Genome Sciences, Inc., or GSK. Other operating expense was $42.9 million for the
six months ended June 30, 2019 and included a take-or-pay purchase obligation
under our manufacturing agreement with GSK. Consistent with our decision to
cease active development of M923, we canceled our manufacturing runs scheduled
through 2020 and recorded a charge of $20.9 million in the three months ended
June 30, 2019, representing the minimum purchase obligation. Since the utility
of the remaining minimum purchase commitments for the calendar years 2021
through 2022 was deemed impaired at June 30, 2019, we recorded an additional
charge of $22.0 million during the six months ended June 30, 2019.

Restructuring

Restructuring charges consist of severance, bonus, share-based compensation, and impairment of equipment associated with our workforce reduction in October 2018.

Other Income, Net



Other income, net includes other items of non-operating income and expense.
Other income, net was $1.5 million and $5.9 million for the six months ended
June 30, 2020 and 2019, respectively. The decrease of $4.4 million, or 75%, from
the six months ended June 30, 2019 to the six months ended June 30, 2020 was
primarily the result of interest expense recognized on the purchase commitments
under our manufacturing agreement with GSK and lower interest income due to
lower market yields on our investments.

Equity Financings



In December 2019, we sold an aggregate of approximately 16.7 million shares of
our common stock through an underwritten public offering at a price to the
public of $15.50 per share. As a result of the offering, which includes the
exercise in full of the underwriter's option to purchase additional shares of
common stock, we received aggregate net proceeds of approximately $244.2
million, after deducting underwriting discounts and commissions and other
offering expenses.

In August 2019, we entered into a sales agreement, or Sales Agreement, with
Stifel, Nicolaus & Company, Incorporated, or Stifel, pursuant to which we may
sell from time to time, at our option, up to an aggregate of $100.0 million of
shares of our common stock through Stifel, as sales agent or principal. Sales of
the common stock, if any, will be made by methods deemed to be "at the market
offerings." We have agreed to pay Stifel a commission of up to 3% of the gross
proceeds from the sale of the shares of our common stock, if any. The Sales
Agreement will terminate upon the earliest of: (a) the sale of $100.0 million of
shares of our common stock or (b) the termination of the Sales Agreement by us
or Stifel. As of June 30, 2020, we have not sold any shares of common stock
under this program.

In December 2018, we sold an aggregate of 20.0 million shares of common stock
through an underwritten public offering at a price to the public of $11.50 per
share. As a result of the offering, which includes the exercise in full of the
underwriter's option to purchase additional shares of common stock, we received
aggregate net proceeds of approximately $217.8 million, after deducting
underwriting discounts and commissions and other offering expenses.

Liquidity and Capital Resources

At June 30, 2020, we had $450.6 million in cash, cash equivalents and marketable securities. In addition, we also held $1.8 million in restricted cash.



We have funded our operations primarily through the sale of equity securities
and payments received under our collaboration and license agreements, including
our share of profits from Sandoz' sales of Enoxaparin Sodium Injection and
GLATOPA. We expect to fund our planned operating and expenditure requirements
through a combination of current cash, cash equivalents and marketable
securities; equity financings; and milestone payments and product revenues under
existing collaboration agreements. We may also seek funding from new
collaborations and strategic alliances, debt financings and other financial
arrangements. Future funding transactions may or may not be similar to our prior
funding transactions. There can be no assurance that future funding transactions
will be available on favorable terms, or at all. We currently believe that our
current capital resources and projected milestone payments and product revenues
will be sufficient to meet our operating requirements through at least the third
quarter of 2021.

Cash, Cash Equivalents and Marketable Securities
Our funds at June 30, 2020 were primarily invested in commercial paper,
overnight repurchase agreements, asset-backed securities, United States treasury
securities, corporate debt securities and United States money market funds,
directly or through managed funds, with remaining maturities of 12 months or
less. Our cash is deposited in and invested through highly rated financial
institutions in North America. The composition and mix of cash, cash equivalents
and marketable securities may change frequently as a result of our evaluation of
conditions in the financial markets, the maturity of specific investments, and
our near term liquidity needs.
We do not believe that our cash equivalents and marketable securities were
subject to significant market risk at June 30, 2020.
                                                                              Six Months Ended June 30,

Cash used in operating activities

The cash used in operating activities generally approximates our net loss adjusted for non-cash items and changes in operating assets and liabilities.

Critical Accounting Policies and Estimates

Our management's discussion and analysis of our financial condition and results
of operations is based on our consolidated financial statements, which have been
prepared in accordance with United States generally accepted accounting
principles. The preparation of these 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 consolidated financial statements, as well as the reported revenue
generated 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. We believe that the
accounting policies discussed in Part II, Item 7 "Management's Discussion and
Analysis of Financial Condition and Results of Operations" of our Annual Report
on Form 10-K for the year ended December 31, 2019 are critical to understanding
our historical and future performance, as these policies relate to the more
significant areas involving management's judgments and estimates. There have
been no material changes to our critical accounting policies since the filing of
such Form 10-K.

New Accounting Standards

Please refer to Note 1 "Nature of Business and Basis of Presentation" to our
condensed consolidated financial statements contained in Part I, Item I of this
Quarterly Report on Form 10-Q for a discussion of new accounting standards.
