PART I

Item 1. Business

Overview

We  are a globally focused, clinical-stage biopharmaceutical  company dedicated to becoming a
leader in the discovery and development of innovative, molecularly targeted and  immuno-oncology
drugs for the treatment of cancer. We  believe the next  generation of  cancer  treatment will utilize
therapeutics both as monotherapies and  in  combination to attack multiple underlying mechanisms of
cancer cell growth and survival. We further believe that  discovery of  next-generation  cancer therapies
requires new research tools. To that end, we  have developed a proprietary cancer biology platform that
addresses the importance of tumor-immune system interactions  and the value of primary biopsies in
developing new models to support our  drug  discovery effort.

Our strategy is to develop a pipeline  of drug candidates with the  potential to be best-in-class
monotherapies and also important components of multiple-agent combination regimens. Over the last
six years, using our cancer biology platform,  we have developed  clinical-stage drug candidates  that
inhibit the important oncology targets  Bruton’s tyrosine kinase,  or  BTK,  RAF dimer  protein complex
and PARP family of proteins, and an  immuno-oncology  agent  that inhibits the immune  checkpoint
protein receptor PD-1. For each of our molecularly targeted  drug candidates, we  have achieved
proof-of-concept by observing objective responses in  defined patient  populations. Our BTK inhibitor is
currently in pivotal studies in North America, Europe, Australia, New Zealand, and  China. Our PD-1,
PARP and RAF dimer inhibitors are  currently in  the dose-expansion  phases of their respective  clinical
trials. As of March 20, 2017, trials of our  four  clinical-stage drug  candidates, as monotherapies and in
combination, have enrolled a total of over  980 patients. We have Investigational New Drug,  or IND,
Applications in effect for our BTK, PD-1 and PARP inhibitors  with the  U.S. Food  and Drug
Administration, or FDA. All four of our drug candidates are in the clinic in China, including our BTK
drug candidate being in two pivotal studies. We  believe that each of our  clinical-stage drug candidates
is the first in their respective classes  being  developed in China under the  Category  1.1 domestic
regulatory pathway to enter into human  testing and to present clinical data.

Our research operations are in China, which  we believe confers several advantages including access

to a deep scientific talent pool and proximity  to  extensive  preclinical study and clinical trial resources
through collaborations with leading cancer hospitals  in China.  Beyond the substantial market
opportunities we expect to have globally, we believe  our  location in  China provides  us the opportunity
to bring best-in-class and/or first-in-class  monotherapies and combination therapeutics  to  our home
market where many global standard-of-care therapies are not currently  approved or available. We have
assembled a team of 348 individuals in  China, the United States, and Australia with deep scientific
talent and extensive global pharmaceutical experience who  are deeply committed to advancing our
mission to become a global leader in next-generation cancer therapies.

We  believe that oncology treatment has entered  an era  of  revolutionary  change  in which cancer

drugs will be  used both as monotherapy  and in combination  to  attack multiple underlying mechanisms
of cancer cell growth and survival. Due  to  breakthroughs in  gene sequencing and methods  of tumor
characterization, cancer is rapidly being redefined from a paradigm  of classification based  on tissue of
origin to molecular characteristics. As  a result, this ability to  better classify cancers has  enabled the
development of molecularly targeted drugs that  address specific cancer subpopulations and  provide high
response rates in tumors with particular  mutations. In addition, the development  of  immuno-oncology
agents such as antibodies targeting the CTLA-4  and PD-1 protein  receptors and  the PD-L1 protein has
demonstrated the importance of the human  immune system in  cancer therapy and  the potential for

3

more durable responses from agents  that activate  the immune system to identify and eliminate tumors.
We  believe that the future of cancer therapy  will involve combinations of molecularly  targeted  and
immuno-oncology drugs tailored to particular tumor sub-groups and have directed our  research  efforts
at both types of drugs.

Our belief that this fundamental shift  was about  to  occur in  cancer research led us early in  our
history to develop a cancer biology platform  that addresses the importance  of  tumor-immune system
interactions and the value of primary  tumor  biopsies in  developing  new  models. Our proximity to
leading cancer treatment centers in Beijing  and our close  relationships with clinicians who treat  patients
and perform biopsies and surgeries at  those centers have allowed us to develop an extensive collection
of in vivo, ex vivo and in vitro cancer models. Given our belief that the human immune system can  play
an important role  in combating cancer and that future  treatments  will involve combination therapies,
we have introduced elements of a functional immune system into these  models. Our  proprietary models
allow our research team to better select targets and to screen and  evaluate  therapeutic  agents that we
believe have significant potential alone or in combination for treating a variety of  cancers. Our models
are a key component in the screening cascade we follow in our  drug discovery  effort and  permit us  to
evaluate potential  drug candidates in conditions that much better  approximate a patient’s cancer at the
time of  treatment. This is particularly significant when drug  discovery requires  evaluation not only of
monotherapies but also multiple combinations and regimens targeting specific  mutations while
simultaneously immobilizing the defenses  cancer cells mount against the human immune system.

Since  our inception in 2010, we have  raised  approximately  $170 million  in private  equity financing

and  $10 million in  non-convertible debt financings. On February 8, 2016 and  November 23, 2016, we
completed our initial and follow-on public offerings, and received net proceeds of $166  million and
$199 million, respectively, after deducting  underwriting  discounts and  offering  expenses.

Next Generation of Cancer Treatment

We believe that oncology treatment is rapidly  evolving, offering  patients the promise of more
frequent and more durable responses that  improve survival  from months to  years  while avoiding  the
severe toxicities typically associated with chemotherapy. While these outcomes may occasionally be
achieved with monotherapy, we believe  that the emergence of resistance is  a major problem and that
better outcomes will be achievable by  combining multiple drugs as  it is  done in  treating  infectious
diseases.

The next generation of cancer therapies  will be based, we believe, on advances  in four areas:

(cid:129) Reclassification of disease based on underlying molecular defect. Due to breakthroughs in gene

sequencing and methods of tumor characterization, cancer is  increasingly being redefined from a
paradigm of tumor classification based  on originating tissue type, such  as lung, colorectal  or
ovarian, to one of characterization based  on the genetic  aberrations and signature  gene
expression patterns, such as in HER2,  BRCA, BRAF, ALK and EGFR. As  a result, many  more
disease subpopulations can be specifically  targeted,  resulting in  more effective treatment  than
was possible in the past. Disease classifications are substantially more sophisticated than 10 years
ago, and we believe they will become increasingly  so in  the future.

(cid:129) Effective molecularly targeted therapy, but often limited  durability. The ability to better understand
the mechanisms underlying cancer has allowed the development of effective drugs that target
important molecular drivers and generate high response  rates  in tumors  with these drivers.
Examples of approved drugs include gefitinib  and erlotinib  for patients with EGFR  mutations,
crizotinib and ceritinib for patients with ALK translocations, and vemurafenib  and dabrafenib
for patients with BRAF mutations. Unfortunately, in  many  of these  cases, responses have  been
relatively short-lived as cancers can develop alternative mechanisms  to  compensate and
ultimately bypass these drugs’ blockade of molecular  signaling. For example, while 52% of

4

previously treated metastatic melanoma patients with BRAF  V600E achieved an objective
response once treated with vemurafenib, the median duration of response was only 6.5 months.

(cid:129) Immune checkpoint inhibitors have shown remarkable  clinical  benefit, demonstrating the power of the

immuno-oncology approach. Improved understanding of cancer immunology has  led  to  the
identification of critical immune checkpoints—i.e., mechanisms  by which cancer  cells  evade the
surveillance of the immune system. Inhibitors  of the immune  checkpoints CTLA-4 and PD-1
have shown success in the clinic. Two  PD-1 monoclonal antibodies, nivolumab and
pembrolizumab, and one PD-L1 monoclonal antibody, atezolizumab, have been  approved by the
FDA. To date, the FDA has approved immune checkpoint inhibitors as monotherapy in  a
number of cancers, including melanoma, non-small cell lung cancer, or NSCLC, kidney cancer,
Hodgkin’s lymphoma, bladder cancer,  and head  and neck squamous  cell  carcinoma, or HNSCC.
Microsatellite instability-high, or MSI-h  cancers and Merkel  cell  carcinoma are also under FDA
review for approval. In addition to these indications, immune checkpoint  inhibitors  are being
studied as monotherapy in clinical trials in  a wide spectrum  of cancers. Some  of  these  trials have
advanced to the pivotal stage, such as gastric cancer,  glioblastoma, liver cancer, esophageal
cancer, small cell lung cancer, or SCLC,  triple  negative breast cancer,  or  TNBC, and  cutaneous
squamous cell carcinoma. Among these indications, immune  checkpoint inhibitors have
demonstrated superior overall survival in  melanoma, NSCLC, kidney cancer, bladder cancer,
HNSCC, and gastric cancer in large randomized controlled clinical  trials. Although certain
distinct toxicities associated with PD-1 and PD-L1 antibodies have  been observed,  these agents
have been generally well-tolerated.

(cid:129) The need for and early promise of combination therapy. While clinical data with molecularly
targeted drugs as monotherapy have been encouraging, achieving  a high rate of durable
responses remains difficult in most cancer types. In  addition, objective responses to checkpoint
inhibitor monotherapies including PD-1, PD-L1 and CTLA-4 antibodies have  been achieved in
still small portions of unselected, solid  tumor patients.  Although the biological mechanisms
underlying combinations are being explored  in the  field, recent third-party clinical studies have
demonstrated the potential of combination therapy to achieve high tumor response rates, as are
often seen with targeted therapy, but  with greater durability, as is  seen with immuno-therapy
agents. The combination of targeted and immuno-therapies may generate durable responses  with
much  better survival rates.

We  believe that the industry-standard for cancer biology models has not evolved along with current

oncology research and drug discovery  and  thus is an insufficient framework from which to develop the
next generation of oncology drugs we  envision. In response, we have built a comprehensive cancer
biology platform specifically to address a new generation of cancer treatments.

Next-Generation Cancer Biology Platform

Fundamental changes in cancer research led us  early  in our  history to develop  a cancer biology

platform that incorporates improved models and  processes better suited to drug discovery  in the new
world of immuno-oncology combinations and addresses the importance of tumor-immune system
interactions and the value of primary  biopsies.  Conventional models for oncology drug discovery have
used cultured cell lines that are often decades  old and have characteristics that are not representative
of the tumors in actual cancer patients. In addition, tumors from these cell lines have been transplanted
in immune-compromised hosts in commonly-used  xenograft tumor  models. Therefore, animal models
utilizing these cell lines have  limited predictive value  for new  therapies. While animal models derived
from surgical samples, such as patient-derived xenograft models, or  PDX models, are an improvement
over the old cell lines, a surgical sample is unlikely to represent the state of the cancer at the time of
intended treatment. Because conventional  models, including PDX models, require the use of immune-
deficient animals, they cannot mimic  interactions between the tumor and the  host immune system.

5

The cancer biology platform we developed enables us to test a large panel of tumor  models for

sensitivity to the drug candidates we  generated, identify drug-resistance mechanisms in many cancers,
explore combination strategies and regimens,  and  improve  our  understanding of the  contributions of
tumor micro- and macro-environments in  cancer treatments.

Scientific Approach. Our platform brings together the following:

(cid:129) Access to a broad array of primary patient biopsies and  tissue samples, enabled by our proximity
to and partnerships with leading China-based oncology centers, allows  us to build novel in vivo,
ex vivo and in vitro models that we believe more accurately represent  patients’ cancer  disease
states at the time of treatment.

(cid:129) Methods for better approximating the interactions between a tumor and a patient’s immune

system, including:

(cid:129) Introduction of elements of the human immune system into our in vivo, ex vivo and in vitro

models;

(cid:129) Creation of a variety of novel assays to investigate the effects of drug combinations and
study their impacts on the human immune system and the tumor microenvironment;  and

(cid:129) An effective screening cascade for oncology drug  development that incorporates all of these

elements.

Sustainable Leadership Position. We believe that our early recognition  of  the importance of tumor-

immune system interactions and the  value of primary biopsies in developing new models for future
cancer research has allowed us to develop a  proprietary  cancer biology platform that provides
significant competitive advantages in developing the next generation of cancer therapeutics.

We  believe that several of these advantages  are sustainable:

(cid:129) Our close relationships with clinicians and our proximity to major oncology centers in  China
provide us convenient and difficult-to-replicate  access to primary tissue samples that greatly
enhance the effectiveness of our oncology  models.

(cid:129) Our time and effort in developing and validating new models and processes, through the

commitment and focus of our large scientific team,  has  allowed us to advance our  capabilities
meaningfully ahead of many current  cancer drug development approaches. Over the last six
years, our team of over 80 biologists  has  been focused on the  continued development of our
cancer biology platform.

(cid:129) Our non-hierarchical structure and  highly  cooperative  organizational  culture allows us to access
the cross-functional capabilities needed to develop, maintain and continually improve our new
generation cancer biology platform.

Our robust preclinical and clinical pipeline demonstrates our  significant commitment and ability to

devote the necessary time, energy and resources  required to build, validate and continue to advance
our  cancer biology platform. Our platform has  enabled us  to  advance four candidates to the clinic and
to execute our combination strategy. We believe we are  one of only two companies  today to wholly own
both a clinical-stage BTK inhibitor for cancer  treatment and PD-1 inhibitor and one of the few
companies to have discovered, and advanced to the clinical stage, a PARP inhibitor and PD-1 inhibitor
or a BRAF inhibitor and PD-1 inhibitor for use as combination therapies. We believe that our cancer
biology platform is critical to developing rational combinations that enable us to become a leader  in
next-generation cancer therapies.

Our Clinical-Stage Drug Candidates

We  have used our cancer biology platform to develop  four clinical-stage drug candidates that we
believe have the potential to be best-in-class or first-in-class.  In addition, we believe that each has  the
potential to be an important component  of a  drug combination addressing  major unmet medical needs.

Moreover, we believe that compounds in our clinical and preclinical  pipeline have  the potential to

be first-in-class therapeutics in China, and,  as locally developed compounds, to qualify for a separate,
and potentially accelerated, regulatory  path.

Over time, we intend to strengthen our position  with additional drug combinations utilizing our

own drugs and in some cases third-party  drugs to compete globally as first-in-combination and
best-in-combination cancer therapies.

BGB-3111, Bruton’s Tyrosine Kinase Inhibitor

BGB-3111 is a potent and highly selective small molecule BTK inhibitor. We  are  currently

developing BGB-3111 as a monotherapy  and in  combination with  other therapies  for the  treatment of a
variety  of lymphomas. BGB-3111 has demonstrated higher selectivity against  BTK than ibrutinib, the
only BTK inhibitor currently approved  by the FDA and the European Medicines Agency, or  EMA,
based on  biochemical assays and higher exposure than ibrutinib based  on their respective Phase 1
experience.

8

In addition, we believe BGB-3111 is  the only BTK inhibitor that has demonstrated  sustained target

inhibition in disease-relevant tissues.  Our  preclinical data  show that  target  inhibition  by  ibrutinib at
disease relevant tissues, such as the lymph node,  bone marrow, and spleen,  in mice and  rats was not
sustained over a 24-hour period. Published clinical  data on ibrutinib show that ibrutinib’s  target
inhibition in the blood is borderline at the approved  dose of  420 mg  once a day,  with BTK  occupancy
in a significant portion of patients below 80%.

As of March 20, 2017, we have enrolled over  340 patients in monotherapy and combination trials

of BGB-3111. In January 2017, we initiated a global, multi-center randomized  Phase 3  trial  in
Waldenstr¨om’s Macroglobulinemia, or WM that will  enroll approximately 170 patients at  clinical sites in
North America, Europe, Australia, and New Zealand. Subsequently, in March 2017, we initiated two
single-arm, open-label, multi-center,  pivotal studies in China in relapsed or  refractory chronic
lymphocytic leukemia, or CLL, or small  lymphocytic lymphoma,  or  SLL,  and in  relapsed  or refractory
mantle cell lymphoma, or MCL, respectively. In addition, we have completed  the dose-escalation  phase
of our Phase 1 trial in Australia, and we  are  continuing  the dose-expansion  phase in patients with select
lymphoid malignancies including CLL, diffuse large B-cell  lymphoma, or DLBCL, follicular lymphoma,
or FL, MCL, marginal zone lymphoma, or  MZL, WM, hairy cell lymphoma, or  HCL.  In the  completed
dose-escalation phase of our clinical trial, no  protocol-defined dose-limiting  toxicities were observed.
BGB-3111 achieved several-fold higher exposure  levels compared  to  that seen  for the  approved doses
of ibrutinib. Proof-of-concept has been established  for BGB-3111 with clinical  data  indicating that
BGB-3111 is a potent BTK inhibitor  with anti-tumor  activity observed in multiple  types of lymphomas
starting at the lowest dose tested, 40 mg  once daily, or QD. We have  also initiated a combination  study
in Australia and the United States with obinutuzumab, an anti-CD20 monoclonal antibody approved  for
CLL.

Mechanism of Action

BTK is a key component of the B-cell  receptor,  or BCR, signaling pathway and is  an important

regulator of cell proliferation and cell  survival in various lymphomas. BTK inhibitors block
BCR-induced BTK activation and its downstream signaling, leading  to  growth inhibition and cell death
in certain malignant white blood cells called B-cells. BGB-3111 is  an  orally active inhibitor of BTK  that
covalently binds to the cysteine Cys-481 of BTK, resulting in irreversible inactivation of the kinase.  It
has also been shown that BTK inhibitors can inhibit solid tumor  growth by regulating the  tumor
microenvironment in preclinical animal models.

Market Opportunity

Lymphomas are a group of blood-borne cancers  involving lymphatic cells  of the immune  system.

They can be broadly categorized into non-Hodgkin’s lymphomas, chronic B-cell  leukemias,
predominantly CLL, and acute B-cell  leukemias.  Depending on the origin  of the cancer cells,
lymphomas are also characterized as  B-cell  or T-cell lymphomas. B-cell  lymphomas make  up
approximately 85% of non-Hodgkin’s  lymphomas  and comprise  a  variety  of  specific diseases  involving
B-cells at differing stages of maturation  or differentiation.  Preliminary  data from  animal models
involving BGB-3111 and third-party BTK  inhibitors  also suggest potential applications in  solid tumors
and inflammatory diseases, which could  substantially expand our market opportunity.

Current Therapies and Limitations

Conventional methods of treatment of lymphomas vary according  to  the specific  disease  or
histology, but generally include chemotherapy,  antibodies  directed  at CD20, and, less frequently,
radiation. Recently, significant progress  has  been made  in the development  of new therapies for
lymphomas, including BCR signaling  inhibitors,  primarily  with the BTK inhibitor ibrutinib and the
PI3K delta inhibitor idelalisib. In addition,  there are other inhibitors of BCR signaling pathways in
development, such as PI3K delta/gamma,  IRAK4 and SYK.

The BTK inhibitor ibrutinib was first  approved by  the FDA in 2013 for  the treatment of  patients

with MCL who have received at least  one  prior therapy. Since  2013, ibrutinib has received
supplemental FDA approvals for the  treatment of  patients with CLL, CLL  patients  with 17p deletion,
patients with WM, and MZL patients  who have received  at least  one  prior anti-CD20-based therapy.
Ibrutinib is also approved by the EMA for  treatment of  patients with MCL, CLL,  or WM. Ibrutinib has
subsequently been approved in over  40 countries,  but not China. Reported  global sales of ibrutinib
were approximately $2 billion in 2016.

Despite the clinical and commercial  success  of ibrutinib, we  believe based on its product profile

that meaningful differentiation is possible in at least the following aspects:

(cid:129) Safety and tolerability. Although ibrutinib has shown a favorable  safety profile compared to

traditional chemotherapies, it is associated with  adverse  reactions  that can limit its tolerability as
a chronic treatment and in some cases can  be  treatment-limiting  or life-threatening. These
adverse reactions—including diarrhea, thrombocytopenia, or low blood platelet count, bleeding
and AF—are believed to be due to ibrutinib’s broad inhibition of  kinases other than BTK,
including EGFR, JAK3 and TEC.

(cid:129) Sustainable target inhibition in disease  originating tissue. Although ibrutinib induced sustained
BTK inhibition when measured in the plasma of patients, our preclinical studies of ibrutinib
show that target inhibition in disease-relevant tissues, such as the lymph node,  bone marrow and
spleen, in mice and rats was not sustained  over a 24-hour period.

(cid:129) Oral bioavailability. Ibrutinib has shown 7–23% oral bioavailability in  preclinical studies, as

evidenced by the daily dose of 420 mg or 560 mg required  in the  clinic.

10

(cid:129) Combinability with ADCC-dependent antibodies. Anti-CD20 agents, such as rituximab,

obinutuzumab and ofatumumab, are considered effective  therapies for lymphomas.  Several
preclinical studies have demonstrated that ibrutinib,  potentially due to its inhibitory activity
against ITK, interferes with rituximab-medicated ADCC,  which is the mechanism by which
rituximab and other anti-CD20 antibodies  are believed to exert their immune defense activities.
Therefore, these preclinical data suggest  that the  activity of rituximab and other
ADCC-dependent antibodies may be  reduced when combined with ibrutinib.

Potential Advantages of BGB-3111

We  believe, based  on our preclinical and clinical  data, that BGB-3111 has the potential to be

differentiated from ibrutinib in the following respects:

(cid:129) Better safety and tolerability. Based on our preclinical studies, we believe BGB-3111  is more
selective than ibrutinib in the inhibition of BTK  and has less  off target  inhibition of other
kinases, including EGFR, ITK, JAK3, HER2  and TEC,  which  we  believe are associated  with
ibrutinib toxicity. Results from our preclinical biochemical  and cellular assays  show that
BGB-3111 has similar potency for BTK  as compared  to  ibrutinib while  being  less  active  against
other  kinase targets than ibrutinib, as reflected by  the  higher dose required  to  inhibit half the
enzymatic activity, or IC  50 . Based on the selectivity of BGB-3111 relative to ibrutinib, a 2-  to
70-fold higher concentration of BGB-3111 is required  to  achieve  similar levels of inhibition in
these other targets as compared to ibrutinib. Therefore, BGB-3111 has the potential  to  be
associated with fewer toxicities.

(cid:129) More sustained inhibition in disease originating  tissue. In our preclinical studies, BGB-3111 has
demonstrated favorable pharmacokinetic properties. The  comparatively high drug level of
BGB-3111 in disease originating tissue  as demonstrated in  the clinic could potentially translate
into a more complete and sustainable inhibition and a better quality of response than  ibrutinib.
Ibrutinib demonstrated a dose-dependent BTK  occupancy  in PBMCs, during its dose-escalation
study. However, even at 420 mg, its approved dose for CLL,  ibrutinib did not achieve complete
or sustained target occupancy in PBMCs in a significant proportion of patients. In addition,
BGB-3111’s favorable safety profile may allow  higher drug exposure, which could result in more
sustained target inhibition. Available data from our completed dose-escalation  trial  suggest that
BGB-3111 achieved several fold higher  exposure levels compared to that  achieved by the
approved doses of ibrutinib in its Phase 1 study. Paired biopsy data  from our Phase  1 study  in
Australia indicate that BGB-3111 is able to sustainably inhibit BTK in the lymph node,
especially with 160 mg twice daily, or BID  dosing.

(cid:129) Better oral bioavailability. BGB-3111 has shown oral bioavailability  of 25–47% in  our preclinical

animal studies. Based on human data generated in our  dose-escalation trial  compared to
reported data for ibrutinib, BGB-3111  has better oral bioavailability than ibrutinib.
Pharmacokinetic data from our clinical studies show a robust and dose-dependent increase in
drug exposure and the drug exposure of BGB-3111 at 80 mg  QD was comparable to that
reported for ibrutinib at 560 mg QD. In  addition, the free drug concentration of BGB-3111 at
40 mg QD was comparable to that reported for  ibrutinib  at 560 mg QD.  Lastly,
pharmacokinetics data for BGB-3111  suggest  that there appears to be far  less  interpatient
variability in drug exposure as compared to ibrutinib.

(cid:129) Better combinability with ADCC-dependent antibodies. Our preclinical data show that BGB-3111
has less off-target inhibition for ITK than ibrutinib in biochemical and cell models. BGB-3111
displayed a more limited inhibitory effect on rituximab-induced ADCC than ibrutinib  in
cell-based studies. In a human MCL xenograft model the addition of  rituximab to ibrutinib did
not improve tumor activity as compared to ibrutinib as a monotherapy. However,  the

11

combination of rituximab and BGB-3111  demonstrated improved anti-tumor activity as
compared to either as a monotherapy. We  believe this may translate into better activity in
patients when BGB-3111 is combined with  rituximab or  other ADCC-dependent  antibody
therapies.

Summary of Clinical Results

As of March 20, 2017, over 340 patients have been enrolled in monotherapy and combination trials

of BGB-3111. Preliminary data from  our  Phase  1 trial suggest that  BGB-3111 is well-tolerated. The
multi-center, open-label Phase 1 trial  is being  conducted in Australia, New Zealand,  the United  States
and South Korea to assess the safety, tolerability, pharmacokinetic properties and  preliminary activity
of BGB-3111 as a monotherapy in patients  with different subtypes of B-cell malignancies, including
CLL, DLBCL, FL, MCL, MZL, WM,  and HCL. We have  completed the dose-escalation phase,  and we
are currently in the dose-expansion phase. The initial results of  the  dose-escalation phase  and
dose-expansion phase of our clinical  trial  show  that, consistent with  BGB-3111’s pharmacokinetic
profile, complete and sustained 24-hour BTK occupancy in  the blood was observed in all tested
patients, starting at the lowest dose of  40  mg QD. In  addition, sustained full BTK occupancy was
observed  in the lymph node especially for the  160 mg  BID dosing regimen. No protocol-defined
dose-limiting toxicities were observed  and only one  treatment discontinuations due to drug-related
adverse events, or AES was reported  as  of October 3, 2016, the most  recent data analysis. Based on the
pharmacokinetics, pharmacodynamics,  safety  and efficacy evaluation of BGB-3111 in the
dose-escalation phase, 160 mg BID has been selected as the Phase 3 dose. Proof-of-concept has been
established for BGB-3111 with clinical data  suggesting  that BGB-3111  is a potent BTK inhibitor with
objective anti-tumor activity observed in  multiple types of  lymphomas  including  CLL, MCL, and WM.

On December 5, 2016, we presented data from  our Phase 1 trial  for  a  total of 33  WM patients at

the 2016 American Society of Hematology  Annual  Meeting. Forty-five relapsed  / refractory  or
treatment na¨ıve WM patients were enrolled in the Phase  1 trial  as  of  November 21, 2016, of which
33 patients were evaluable for safety  and  response at  the cutoff date  of October 3, 2016. Responses
were determined according to the modified  Sixth International  Workshop on WM  criteria.

In the most recent data analysis, which  had a cutoff  of October  3, 2016, AEs were generally mild
in severity, self-limited, and usually encountered only in the earlier part of  the treatment course. The
most frequent AEs ((cid:2)20%) of any attribution were upper respiratory tract  infection (39%),  petechiae
(spots that appear on the skin as a result  of bleeding) / purpura (subcutaneous bleeding)  / contusion
(33%), nausea (24%), diarrhea (24%),  and constipation (21%), all  grade 1 or 2  in severity except for
one case of diarrhea (3%). Four serious adverse events, or  SAEs, were assessed as  possibly  related to
BGB-3111, including one case each of grade  3 cryptococcal meningitis, grade 3  pneumonia, grade 2
atrial fibrillation, or AF, and grade 2 vomiting. Other grade 3  or greater events considered possibly
related to BGB-3111 included two cases  of  neutropenia and one case  each of diarrhea, hypertension,
increased liver function test, pulmonary hypertension,  and vomiting.  In total,  three cases of AF were
reported (all grade 1 or 2), and two of the  three occurred in patients  with pre-existing AF. No serious
hemorrhage ((cid:2) grade  3 hemorrhage or central nervous  system, or  CNS,  hemorrhage of any  grade) was
reported. The only treatment  discontinuation was  due to exacerbation of  pre-existing bronchiectasis in a
patient who achieved a very good partial response, or VGPR, on BGB-3111, and the subsequent death
of this patient was also the only fatal  event in the study  and was assessed by the investigator to be
unrelated to study treatment.

14

After a median follow-up of 9.6 months (3.0–24.7 months), 32 of the 33  patients were  evaluable  for

response as one patient had IgM < 500  mg/dl at  baseline. The rate of  overall response, defined as
minor response, or MR, or better, was  94%. The major response rate, defined as partial response, or
PR, or better, was 78% (25 out of 32 patients).  VGPRs ((cid:2)90% reduction or normalization of IgM and
reduction in lymphadenopathy / splenomegaly) have  been observed  in 34% (11 out of 32  patients) and
PRs (50–89% reduction in IgM and reduction in lymphadenopathy / splenomegaly) in 44% (14 out of
32 patients) of patients to date. IgM  decreased  from a median of 32.5g/l at baseline to 4.0g/l, and
hemoglobin increased from a median  of 10.3g/dl  at baseline  to  13.6g/dl. There have  been no cases of
disease progression.

MYD88 and CXCR4 mutational analysis results were available for  23 patients who were evaluable
for response at the data cutoff. Of 18 evaluable patients with the MYD88L265P / CXCR4WT genotype,
eight achieved VGPRs, seven achieved  PRs, two achieved MRs, and one had stable disease, or  SD.
The two patients with the  MYD88L265P / CXCR4WHIM genotype achieved a PR and an MR,
respectively. Responses were also seen in MYD88WT patients, including one PR, one MR, and  one SD
among three evaluable patients. Analysis  of patient response  by genomic characteristics was ongoing.

The depth of response to BGB-3111  in  the Phase 1 trial improves  with longer  treatment. In
32 evaluable patients who had three cycles of BGB-3111  treatments,  the  VGPR rate was 6%,  the PR
rate was 59%, the MR rate was 25%,  and the SD rate was  9%.  The major response rate was 65%.  In

In addition to data in WM, updated  data  on BGB-3111 in patients with CLL  from the

dose-escalation and dose-expansion phases of the  Phase 1  trial were presented  on December 5, 2016 at
the 2016 American Society of Hematology  Annual  Meeting. As  of November  21, 2016, 63  patients with
CLL or SLL, were enrolled in the study. The data presented were from a total of 46 CLL or  SLL
patients who had at least 12 weeks of follow-up or discontinued  treatment prior to week  12, by the data
cutoff of October 3, 2016.

BGB-3111 was well-tolerated. Only one  patient  had discontinued BGB-3111 treatment for an AE,

a grade 2 pleural effusion. The most frequent AEs ((cid:2) 20%) of any attribution were petechiae  /
purpura  / contusion (48%), upper respiratory tract  infection (33%), fatigue (28%), diarrhea (20%),
cough (20%), and headache (20%), all  of  which were grade 1 or 2 in severity except for one  case of
grade 3 purpura. Three SAEs were assessed as possibly related to BGB-3111, including one case each
of grade 2 cardiac failure, grade 2 pleural  effusion, and grade 3 purpura.  Other grade 3 or greater
events considered possibly related to  treatment  included three cases of neutropenia and  one case of
AF, which was the only AF case reported. The case of purpura was the only major bleeding  event; no
other cases of serious hemorrhage (defined as (cid:2) grade 3 hemorrhage or CNS hemorrhage of  any
grade) were reported.

After a median follow-up of 8.6 months (2.2–20.9 months), the  rate  of overall  response  was

96% (44 out of 46 patients) with PR in 67% (31  out of  46 patients)  and PR  with lymphocytosis in
28% (13 out of 46 patients) of patients. SD  was  observed in  2%  (1 out  of  46 patients) of patients. The
patient who discontinued prior to week  12 due to pleural effusion  was not evaluable for  response.  No
instances of disease progression or Richter’s transformation had  occurred.

In January 2017 we initiated a global, multi-center  randomized Phase 3 pivotal trial in  WM in

which  we plan to enroll approximately 170 patients at clinical  sites in  North America, Europe,
Australia, and New Zealand to determine whether the quality of  response  with BGB-3111 in WM is
superior to that of ibrutinib. The study will compare BGB-3111 with  ibrutinib in relapsed or refractory
WM patients or treatment-na¨ıve WM patients who are inappropriate for chemo-immunotherapy.
Patients will be tested for mutation status of  the MYD88 gene and assigned to MYD88 mutation and
wildtype cohorts accordingly. We expect to enroll 150  patients  in the MYD88 mutation cohorts, who will
be randomized in a 1:1 ratio to receive either BGB-3111 160 mg orally  BID or ibrutinib 420  mg  orally
QD until progression. The primary endpoint  is combined rate of  complete responses, or CRs, and
VGPRs. Secondary endpoints include  major response rate,  progression-free survival,  duration of
response, and symptom resolution. The  randomization will be  stratified by CXCR4 mutational status
and number of lines of prior therapy. Approximately 20 patients with MYD88 wildtype status will be
enrolled in the second cohort and receive  BGB-3111. The patients  will be evaluated for the combined
rate of CRs and VGPRs, major response  rates,  and  safety. Below schematic shows  the design of the
Phase 3 pivotal trial in WM.

Moreover, we are  evaluating BGB-3111  in combination clinical trials. Our preclinical data show

that BGB-3111 has less off-target inhibition for ITK than ibrutinib in biochemical and cell models.
BGB-3111 displayed a more limited inhibitory effect on rituximab-induced  ADCC than ibrutinib in
cell-based studies. As shown in the graph  below, in  a human MCL xenograft model the addition of
rituximab to ibrutinib did not improve  tumor activity as compared to ibrutinib  as a monotherapy.
However, the combination of rituximab and  BGB-3111 demonstrated improved anti-tumor activity  as
compared to either as a monotherapy.  We  believe this may translate into better activity in patients
when BGB-3111 is combined with rituximab or other ADCC-dependent antibody therapies. We
initiated the combination trial with CD20 antibody obinutuzumab in  patients  with B-cell  malignancies
in January 2016, and this trial is currently in  its dose-expansion phase.

We  also explored the combination of BGB-3111  and our PD-1 antibody, BGB-A317  in two
DLBCL primary tumor models. In both models, BGB-3111  showed weak  monotherapy activity.  When
used as a monotherapy BGB-A317 was  only active in  the PD-L1 positive tumor. However,  the
combination of BGB-3111 and BGB-A317  was  highly active, better than either  monotherapy, and
induced tumor regression in both PD-L1 positive and PD-L1 negative models. A combination clinical
trial of BGB-3111 with BGB-A317 was initiated in June  2016 and  is in  its  dose-escalation phase.

In China, we have initiated two pivotal studies for  BGB-3111. In March  2017, we  initiated
single-arm, open-label, multi-center pivotal clinical trials  of BGB-3111 monotherapy  in China in

22

 
 
 
 
 
 
 
 
 
 
 
patients with relapsed or refractory MCL  and in patients  relapsed and refractory CLL or  SLL,
respectively. The primary endpoint in each  of  these trials is  the  objective  response  rate, and secondary
endpoints include progression free survival, duration of response,  time  to  response,  safety, and
tolerability. We believe BGB-3111 is  the first BTK  inhibitor being  developed  in China  under the
Category 1.1 domestic regulatory pathway  to enter  into  human testing  and  to  present  clinical data.

We  plan to expand our registration program  for BGB-3111. In addition, we plan to present data

from the combination studies of BGB-3111 with obinutuzumab and BGB-3111 with BGB-A317  at
medical conferences in 2017.

BGB-A317, PD-1 Antibody

BGB-A317 is an investigational humanized monoclonal antibody against the immune checkpoint

receptor PD-1. We are developing BGB-A317 as a monotherapy and as a combination agent for
various solid-organ and blood-borne cancers. PD-1  is a cell surface  receptor  that  plays an important
role in  down-regulating the immune system  by preventing the activation of certain types  of white blood
cells called T-cells. PD-1 inhibitors remove the blockade of immune activation  by  cancer  cells. We
believe BGB-A317 may be differentiated  from  the currently approved  PD-1 antibodies with  the ability
to bind Fc gamma receptor I specifically  engineered out,  and we believe this  could  potentially result  in
improved activities. In addition, BGB-A317 has a unique binding signature to PD-1  with high  affinity
and  superior target specificity.

We are evaluating BGB-A317 in the ongoing dose-escalation phase of our clinical trial in  relapsed

or refractory solid tumor patients and  combination  trials  with  our PARP inhibitor,  BGB-290 and with
our BTK inhibitor, BGB-3111 respectively, in  Australia. As of March 20, 2017, we have  dosed over 400
patients with BGB-A317 in monotherapy  and  combination  trials. BGB-A317 is the first drug candidate
produced from our immuno-oncology  biologic programs, and  we believe it could serve as one of  the
cornerstones for our immuno-oncology  combination platform.

Mechanism of Action

Cells called cytotoxic T-cells provide  humans an important self-defense mechanism against cancer,
patrolling the body, recognizing cancer  cells due  to  immunogenic  features that differ from normal cells,
and  killing cancer cells by injecting poisonous proteins into them.  T-cells have various  mechanisms built
into them that prevent them from damaging  normal cells, among which is a protein called PD-1
receptor, which is expressed on the surface of T-cells. The most important signaling protein that could
engage PD-1 is called PD-L1, which binds the PD-1  receptor  and sends an inhibitory  signal inside the
T-cell, stopping it from making more poisonous proteins and killing the cells sending the signal via
PD-L1 and other cells nearby. Many types of cancer cells  have hijacked the  PD-L1 expression system
that normally exists in healthy cells. By expressing  PD-L1, cancer cells protect  themselves from being
killed by cytotoxic T-cells. BGB-A317 is a monoclonal antibody designed to  specifically bind to PD-1,
thereby preventing PD-L1 from engaging PD-1. Therefore, we believe  BGB-A317  has the potential to
restore  the cytotoxic T-cell’s ability to kill  cancer  cells.

Market Opportunity

Forecasts of the market for monotherapy  PD-1 and PD-L1 antibodies have increased as  new
tumor types responding to these antibodies  have been identified  and data  has accumulated regarding
their potential efficacy. It is estimated that these inhibitors  will have sales in excess of $36 billion by
2023 across 10 tumors that are the focus  of current immune-oncology studies (i.e.,  melanoma, renal  cell
cancer, lung cancer, gastric cancer, bladder cancer,  HNSCC, triple-negative  breast  cancer, Hodgkin’s
lymphoma, Merkel cell carcinoma, and  liver  cancer).

23

Tumor types that have been shown to  be responsive  to  a PD-1 antibody include those with  the
highest annual incidence and mortality rates  in China. Specifically, in  2012, 38%, 49%,  45%, and 51%
of the worldwide mortalities from lung, esophageal, gastric, and liver cancers respectively occurred in
China. Collectively, these four tumor  types comprised  over 1.6 million new cases in  2012 in China
alone, according to the World Health  Organization.  To our  knowledge, BGB-A317  is the first PD-1
antibody  developed in China to enter  clinical trials and to present clinical data. Due  to  a distinct
regulatory pathway for drug candidates  manufactured in China, we believe that BGB-A317  will  become
an important participant in China’s PD-1 antibody and immuno-oncology market.

Potential Advantages of BGB-A317

We  believe BGB-A317 may be differentiated from  the currently approved  PD-1 antibodies.

Specifically, its ability to bind Fc(cid:3)RI has  been engineered out, resulting in  a cell biology differentiation
compared to the currently approved PD-1 antibodies. Our preclinical  data and published literature
findings, Dahan et al., 2015, suggest  that engagement of  Fc(cid:3)RI may compromise the efficacy of
anti-PD-1 antibodies by attracting immune  suppressive cells and  depleting the  T-cell  population
necessary for attacking the tumor cells.  With limited to no ability to bind  to the receptor, we believe
BGB-A317 could potentially have improved activities. In addition, BGB-A317  has a unique binding
signature to PD-1 with high affinity and  superior target specificity.  In preclinical studies, BGB-A317
showed  better cellular functional activities  in blocking PD-1 mediated reverse signal transduction and  in
activating human T-cells and primary  PBMCs and improved tumor  growth inhibition compared  to
currently approved PD-1 antibodies.

We  believe there could be a large commercial  opportunity in China for PD1 antibodies  as

currently available clinical data suggest  that some of the most prevalent cancers in China  such as lung,
gastric, liver and esophageal cancers are responsive to this class of agents. We believe we are well
positioned to take advantage of this opportunity.  In  addition,  the potential to combine BGB-A317  with
our  multiple clinical-stage and preclinical drug  candidates provides us  with additional shots on  goal.
Based on our preclinical data, we believe a strong rationale  exists  for combining BGB-A317 with our
drug candidates BGB-290, BGB-3111, and BGB-283.  In addition, we are developing  several immuno-
oncology candidates that we intend to  combine  with BGB-A317.

Summary of Clinical Trials

As of March 20, 2017, we have dosed  over 400  patients with BGB-A317 in either monotherapy or
combination trials. In April 2016, we  completed the enrollment for the ongoing dose-escalation phase,
and in May 2016, we initiated the dose-expansion phase of  our Phase 1 clinical trial in  relapsed or
refractory solid tumor patients in Australia,  New Zealand, the  United States, Korea, and  Taiwan.

On November 11, 2016, we presented updated data from the  dose escalation phase of  our ongoing

Phase 1 trial for a total of 103 patients with advanced solid tumors at the Society  for Immunotherapy
of Cancer, or SITC, 31st Annual meeting. The preliminary clinical data  showed that BGB-A317 was
well-tolerated with AEs in keeping with the  class  effect. Among  103 patients evaluable for safety at the
time of  the data cutoff for the current safety  analysis on August 15, 2016,  the most  common treatment-
related AEs ((cid:2) 5%) were fatigue (19%), diarrhea (13%), rash  (11%), pruritus (11%), nausea  (8%),
hypothyroidism (7%), and infusion related reaction  (6%). Treatment-related  SAEs included  four cases
of colitis, two cases of hypotension, and  one case  each of diarrhea, diabetes mellitus, diabetic
ketoacidosis, dyspnea, hypoxia, infusion-related reaction, and pneumonitis. Among  these,  grade 3
treatment-related SAEs included the two cases of hypotension and one case each  of  colitis, diabetes
mellitus, diabetic ketoacidosis, dyspnea,  hypoxia, and pneumonitis. Other treatment-related  grade 3 AEs
included two  cases each of fatigue and  hyperglycemia, and one case each  of  back pain, elevated alanine
aminotransferase and elevated gamma-glutamyl transferase.  The table below summarizes the AE
events.

A mixed patient population of 27 different tumor types was included in this data analyses,  in which
patients with melanoma, NSCLC or  HNSCC were not enrolled, and patients  with renal cell cancer  and
urothelial carcinoma together represented close to 15% of  the enrolled patients. Among  99 patients
evaluable for efficacy as of September  30,  2016, anti-tumor activities  were  observed in  15 patients with
a PR and 23 patients with SD. The PRs include three PRs  in nine renal  cell carcinoma  patients; three

efficacy. One of seven patients with mesothelioma  discontinued therapy due to treatment-related grade
3 pneumonitis prior to obtaining confirmation of an  initial PR. Additionally, two of 23 patients  with
ovarian cancer and one of five patients with cervical cancer  had significant tumor  shrinkage qualifying
for a PR in one imaging assessment but not confirmed in the  subsequent assessment  due  to  disease
progression.

Additional tumor types enrolled in the study include  endometrial, esophageal,  gallbladder,  breast,

and thyroid cancers, cholangiocarcinoma, sarcoma,  glioblastoma, hepatocellular,  anal  squamous cell,
cutaneous squamous cell, adrenocorticoid, and  adenoid  cystic carcinomas, adenocarcinoma  of mandible,
and undifferentiated adenocarcinoma  from teratoma, with  one  to  five  patients each.

To date, we have two internal combination clinical trials  ongoing. In February  2016, we  initiated a

Phase 1 clinical trial of BGB-290 in combination  with BGB-A317. The dose escalation  portion of the
study is currently enrolling subjects with  TNBC, ovarian cancer, fallopian  tube  cancer,  peritoneal
cancer, SCLC, and tumors likely to have DNA damage repair  deficiencies susceptible to PARP
inhibition or likely to respond to a PD-1 blockade. In June 2016,  we initiated a  Phase 1  clinical trial
with BGB-3111 in combination with  BGB-A317  for  the treatment of various B-cell malignancies.

We  have also initiated a Phase 1 open-label, multi-center trial with  BGB-A317  in China  in

December 2016. The Phase 1 open-label,  multi-center  study of BGB-A317 is designed to investigate  the
safety, tolerability, pharmacokinetics,  and  preliminary antitumor activity  of BGB-A317  in Chinese
patients with advanced solid tumors.

We  plan to advance BGB-A317 into  late-stage  development. In addition,  we plan to present the

data from the dose-expansion phase of our  clinical trial at a medical  conference  in 2017. We  also plan
to present data from our combination  trials in 2017.

BGB-290, PARP Inhibitor

BGB-290 is a molecularly targeted, orally available,  potent and  highly selective inhibitor of  PARP1

and  PARP2. We are currently developing  BGB-290 as  a  monotherapy  and  in combination with  other
therapies for the treatment of homologous  recombination deficient  cancers, which are cancers that
contain abnormalities in their DNA molecule  repair mechanisms, making these cancers particularly
sensitive to PARP inhibitors. We believe  BGB-290 has  the potential to be  differentiated  from other
PARP  inhibitors in terms of brain penetration, selectivity, DNA-trapping activity,  and oral
bioavailability.

We have completed the dose-escalation phase of  our clinical trial in Australia  and are conducting

the dose-expansion phase of our clinical  trial. We have  dosed over 110 patients  with BGB-290  in
monotherapy and combination trials as of March  20, 2017. Initial analysis of data from  this trial  has
shown BGB-290 to be well-tolerated. Proof-of-concept  has also been established, with anti-tumor
activity  seen starting at the lowest tested dose and data  suggestive of a wide therapeutic  window.

Mechanism of Action

PARP family members PARP1 and PARP2 are involved in DNA replication and transcriptional
regulation and play essential roles in cell survival in response to DNA damage. PARP1  and PARP2 are
key base-excision-repair proteins that function as DNA damage sensors by binding rapidly to the site of
damaged DNA and modulating a variety of proteins in DNA repair processes. Inhibition of PARPs
prevents the repair of common single-strand DNA breaks which leads to formation of  double-strand
breaks during  DNA replication. Double-strand DNA breaks in normal cells are repaired  by homologous
recombination,  and normal cells are relatively tolerant of PARP inhibition. On the other hand,  cancer
cells with mutations in breast cancer susceptibility gene, or BRCA1/2 genes,  key players in homologous
recombination,  are highly sensitive to PARP inhibition, a phenomenon called ‘‘synthetic lethality’’ that is
the  foundation of the therapeutic utility of PARP inhibitors as a monotherapy  for  BRCA mutant cancers.
In addition to hereditary BRCA1/2 mutations, the synthetic lethal concept  has been broadened  to include
sporadic tumors that display homologous recombination deficiency, or HRD, a gene expression  profile
that resembles that of a BRCA deficient tumor. HRD can stem from somatic mutation of  BRCA1/2,
epigenetic silencing of BRCA genes or genetic or epigenetic loss of function of other genes in
homologous recombination DNA damage repair pathways. Recent third-party  clinical studies have
published  results demonstrating that sensitivity to platinum-based chemotherapies confers  sensitivity to

27

PARP inhibitors in ovarian cancers. Thus, this trial finding may provide an  additional  possibility to
identify and  enrich patient populations that could respond to PARP inhibitors.

Another potential therapeutic utility of PARP inhibitors is rational combination therapy.  PARP
proteins are key factors in DNA repair pathways, in particular, base-excision-repair, which is critical for
the repair of DNA lesions caused by  some chemotherapeutic agents and by  radiation. PARP inhibitors
are hypothesized to potentiate cytotoxicity  of DNA-alkylating  agents  such as  platinum compounds,
temozolomide and ionizing radiation  and  may be used in  combination with these agents  in treating
various cancers. PARP inhibitors are  also  considered  good potential combination partners with
checkpoint inhibitors in part due to increased mutations in tumor as a result of the blockade of DNA
repair by PARP inhibitors.

Market Opportunity

We  believe the market opportunity for PARP inhibitors is large  and expanding in various tumor
histology, settings and patient segments. Many tumor types have  been shown  to  be  responsive to PARP
inhibitors, including ovarian cancer, breast cancer, prostate cancer,  SCLC,  and gastric cancer. PARP
inhibitors have also been explored in  settings beyond  late  lines  with encouraging  results, such  as
maintenance setting. Clinical trials have also shown  that PARP inhibitors are active beyond the initial
population of patients with BRCA mutations. In ovarian cancer and other cancers,  there is growing
understanding and increasing clinical data  indicating that  multiple DNA  repair defects or  HRD,  other
than BRCA mutations could render the tumor cell to be susceptible  to PARP inhibition. Collectively,
we believe the addressable patient population for PARP inhibitors is fast expanding.

Potential Advantages of BGB-290

BGB-290 is a highly potent and selective PARP  inhibitor with favorable oral bioavailability. We

believe BGB-290 has the potential to be differentiated from  other PARP inhibitors, in terms of brain
penetration, selectivity, DNA-trapping  activity, and oral bioavailability.

(cid:129) Brain penetration. BGB-290 has shown significant brain penetration in preclinical models. The
brain/plasma ratio in mice after oral dosing  of 10  mg/kg BGB-290 was approximately 18%.  We
believe the only other PARP inhibitor  currently in development  that has shown  significant brain
penetration is veliparib, which appears to be significantly less potent compared to other  PARP
inhibitors and has minimal DNA-trapping  activity.  BGB-290 has demonstrated strong synergistic
anti-tumor effects with temozolomide  in  treating intracranially implanted glioblastoma
multiforme, consistent with its ability to cross the blood-brain  barrier.

(cid:129) Greater selectivity potentially leading to  improved safety  and tolerability. BGB-290 is a highly active

and selective PARP1 and PARP2 inhibitor in biochemical  and cellular assays. Enhanced
selectivity could potentially translate  into a better safety and tolerability  profile over existing
PARP inhibitors. We believe a favorable safety and tolerability profile could  be  particularly
advantageous for the combined use of BGB-290  with immune checkpoint  inhibitors or
chemotherapeutic agents.

(cid:129) Strong DNA-trapping activity. PARP inhibitors are reported to trap  PARP protein at damaged
DNA sites, creating more cytotoxic DNA lesions. The potency of  DNA-trapping for PARP
inhibitors is shown to be better correlated with  tumor cell growth-inhibition than  inhibition  of
PARP enzyme activity. BGB-290 has demonstrated potent activity across multiple assays:
DNA-trapping, enzymatic and cellular inhibition of PARP and tumor cell growth  inhibition.

(cid:129) Good oral bioavailability. In preclinical animal models, BGB-290 demonstrated bioavailability of
71–76% in animal studies. In the ongoing  dose-escalation phase  of  our clinical  trial,  we observed
a linear and dose-dependent pharmacokinetic  profile  for BGB-290 with approximately two-fold
accumulation at steady state.

Summary of Clinical Results

As of March 20, 2017, we have dosed  over 110  patients with BGB-290 in either  monotherapy or
combination trials. We have completed  the dose-escalation phase and are  evaluating  BGB-290 in the
ongoing dose-expansion phase of our clinical  trial in Australia.

At the 2015 AACR-NCI-EORTC International Conference  on Molecular  Targets and Cancer

Therapeutics, we presented clinical data  from  our Phase 1 clinical trial. As of June 30, 2015, 29
relapsed or refractory solid tumor patients  were enrolled in seven cohorts  receiving  monotherapy
BGB-290 in doses ranging from 2.5 mg BID to 80  mg  BID. Initial analysis  of  data  from this trial
suggests that BGB-290 is well-tolerated.  Few  AEs of  myelosuppression,  no liver toxicity signal,  and few
drug-related grade 3/4 AEs were observed  in the dose-escalation phase.  The  most common  drug-related
AEs were grade 1 and 2 nausea (38%)  and fatigue  (28%). Drug-related grade 3/4  AEs include one
each  (3%) of neutropenia, anemia, hypophosphatemia and  hypokalemia, all grade 3.  As of January  19,
2016, drug-related SAEs reported by  investigators  were three  cases of  grade 3  anemia and  one  case of
shortness of breath.

In February 2016, we initiated a Phase  1 clinical  trial of BGB-290 in combination with BGB-A317.

The dose-escalation phase of the trial  is  currently enrolling  subjects with  TNBC, ovarian cancer,
fallopian tube cancer, peritoneal cancer,  SCLC, and  tumors  likely to have  DNA  damage repair
deficiencies susceptible to PARP inhibition or  likely to respond to a PD-1 blockade.  The
dose-expansion phase will include patients  with BRCA 1/2-mutations or HRDs  who have TNBC,
metastatic castration-resistant prostate  cancer, pancreatic adenocarcinoma, and platinum-sensitive
ovarian, fallopian tube, and primary peritoneal cancers,  as well  as patients with platinum-sensitive
urothelial bladder cancer, pancreatic  adenocarcinoma, SCLC, and gastric or  gastroesophageal junction
cancers. Key objectives in the trial include assessing  safety and tolerability,  maximum tolerated dose,
recommended Phase 2 dose, pharmacokinetics,  and  preliminary  anti-tumor  activity of the BGB-A317
and BGB-290 combination.

In December 2016, we also initiated  a Phase 1 open-label, multi-center trial with BGB-290 in
China. The Phase 1 study is designed to investigate the safety, pharmacokinetics,  and antitumor activity
of BGB-290 in Chinese patients with advanced solid tumors and to determine the recommended
Phase 2 dose in these patients.

We  plan to advance BGB-290 into late-stage development. In addition, we  plan to present the data
from the monotherapy trial of BGB-290 at a medical conference  in 2017. We also plan to present data
from the combination trial in 2017.

We  are in limited collaboration with Merck  KGaA, Darmstadt Germany as further  described in

‘‘—Collaboration with Merck KGaA, Darmstadt  Germany.’’

BGB-283, RAF Dimer Inhibitor

BGB-283 is a small molecule inhibitor of both the  monomer  and  dimer forms of the RAF kinase.

We are currently developing BGB-283 for  the treatment of cancers  with aberrations in the  mitogen-
activated protein kinase, or MAPK, pathway, including  BRAF  gene mutations and KRAS/NRAS gene
mutations where first generation BRAF  inhibitors are not effective. The MAPK pathway  is a chain of
proteins in the cell that communicates a signal  from a receptor on the surface of the cell to the  DNA
in the  nucleus of the cell. This pathway plays an essential  role in  regulating cell proliferation  and
survival. We intend to develop BGB-283 to treat  various  malignancies, including  melanoma, colorectal
cancer, NSCLC, endometrial cancer,  ovarian cancer, pancreatic cancer and papillary thyroid carcinoma.
Currently approved first-generation BRAF inhibitors, vemurafenib and dabrafenib, are  only  active
against the BRAF  monomer. BGB-283 inhibits not only the monomer but  also the dimer forms of
BRAF. We believe BGB-283 has the potential to be a  first-in-class RAF  dimer inhibitor globally.

As of March 20, 2017, we have dosed over 170  patients with  BGB-283. In June 2015, we

completed the dose-escalation phase of our  multi-center, open-label Phase 1 clinical  trial  in Australia
and  New Zealand. We are currently conducting  the multi-arm dose-expansion phase  of  the Phase  1
clinical trial in Australia and New Zealand  and in  April  2016  completed the enrollment for the
dose-expansion phase of our clinical trial  for the  treatment of solid tumors with BRAF mutations
and/or aberrations in the MAPK pathway, including melanoma, thyroid cancer, colorectal  cancer,
NSCLC and other non-V600E BRAF mutated  cancers, and KRAS/NRAS mutated endometrial  cancer,
colorectal cancer, NSCLC and other KRAS/NRAS mutated  cancers.

Mechanism of Action

The MAPK pathway is a chain of proteins  that communicates a signal from a receptor on the
surface of a cell to the DNA in the nucleus  of  the cell. The pathway  includes a small  G protein  (RAS)
and  three protein kinases (RAF, MEK, and ERK). A kinase is  an enzyme that catalyzes  the transfer of
a phosphate group from a donor molecule to an  acceptor. This process often  acts  as an ‘‘on’’ or ‘‘off’’
switch to regulate cellular signaling. The MAPK pathway plays  an essential role in regulating cell
proliferation and survival. Activation of the  RAS-RAF-MEK-ERK kinase cascade by external stimuli
transduces signals from the plasma membrane  into  the cell nucleus  to  control gene expression  and
determine cell fate. Aberrant activation of the MAPK signal  transduction pathway is  frequently  found
in different types of cancers, contributing to increased cell division,  suppressed apoptosis, and enhanced
cell motility and invasion. In many cancers, a defect in  the MAPK pathway leads  to  uncontrolled tumor
growth. The two key components of the MAPK pathway, BRAF and RAS, are two of the  most
frequently mutated genes in human cancers. BRAF  is one of the three kinases that belong  to  the RAF
kinase family. There are three members:  ARAF, BRAF and  CRAF. BRAF  is the most frequently
mutated oncogene in this kinase superfamily. Mutated BRAF and RAS lead to activation of the  MAPK
pathway and promote tumor development  and  growth. Functions of BRAF in the  MAPK pathway are
key  to cell proliferation and survival. Mutations  that lead to activation of  BRAF promote cell
transformation and proliferation and thus positively  correlate with  tumor development and  growth. The
most frequent BRAF mutation, BRAF V600E, causes constitutive activation of  the kinase as  well as
insensitivity to negative feedback mechanisms.  The  mutated BRAF signals  as a monomer, independent
of upstream growth stimuli. It has been  found  that RAF kinases can homo-  and heterodimerize and
form homodimer or heterodimer of RAF proteins.  Dimerization  has been reported  to  be  one of the
key  mechanisms of resistance to first-generation BRAF  inhibitors, such  as vemurafenib and dabrafenib.
The three most common molecular mechanisms of acquired resistance of BRAF V600E melanomas to
RAF inhibitors—NRAS mutation, splicing  of BRAF V600E  that produce a truncated BRAF kinase,
and  BRAF V600E overexpression due to gene  amplification—all result in dimerization  of
BRAF V600E. First-generation BRAF inhibitors only inhibit the BRAF V600E monomer form  at
physiologically meaningful concentrations. In contrast, BGB-283 has been shown to inhibit  both
BRAF V600E monomer and RAF dimer  in BRAF inhibitor sensitive  and resistant melanoma  cell

32

models, which is involved in signaling  downstream from RAS. We believe  this  feature of BGB-283 may
help to address the drug resistance issues in BRAF  mutated tumors  and  further expand its utility into
RAS mutated patient populations.

Market Opportunity

We  believe BGB-283 has applications in  both BRAF mutated cancers  and RAS, including KRAS

and NRAS, mutated cancers. The oncogenic BRAF  V600E mutation  was  detected in approximately 8%
of all human solid tumors, including  approximately 45% of papillary thyroid cancers. Mutations in any
one of the three RAS genes, HRAS, NRAS  or KRAS, are  among  the most  common events in  human
tumorigenesis. KRAS mutations are  detected prominently  in colorectal cancer, NSCLC and  pancreatic
cancer. Additionally, notable KRAS or  NRAS mutation rates have  been reported in  melanoma, ovarian
cancer, endometrial cancer, bladder cancer, biliary cancer,  thyroid  cancer,  leukemia and multiple
myeloma. The first-generation FDA-approved BRAF inhibitors have limited activity outside  of
melanoma, NSCLC and thyroid cancers. In addition,  these first-generation  BRAF  inhibitors do  not
exhibit activity against KRAS and NRAS mutations.

Potential Advantages of BGB-283

BGB-283 is a novel inhibitor of RAF,  in both monomeric and dimeric forms. BGB-283  has

demonstrated potent and reversible inhibitory activities against RAF family kinases,  including wild-type
ARAF, BRAF, CRAF and BRAF V600E,  in  biochemical assays. In  addition,  BGB-283 has  shown
potent inhibitory activity against EGFR  in  biochemical assays  using EGFR kinases, cancer cell lines,
and xenograft models. In BRAF wild-type cells that  harbor the KRAS mutations,  treatment with
BGB-283 resulted in much reduced up-regulation  of  pERK, a phosphorylated form  of  ERK, compared
with vemurafenib in cancer cell models.

In preclinical testing, BGB-283 also retained inhibitory activity in vemurafenib-resistant BRAF
splicing isoform p61-BRAF V600E. Data  generated in preclinical studies  using biochemical, cell-based
and animal studies suggest that BGB-283 could  offer  significant patient benefit  in inhibiting tumors
with aberrations in the RAF MAPK/ERK pathway, including BRAF mutations and KRAS/NRAS
mutations as either monotherapy or in  combination with other cancer  therapies.

We  believe BGB-283 has the potential  to  be  differentiated from  other drug  candidates currently

under development and from approved  first-generation BRAF inhibitors  due  to  the following:

(cid:129) Increased inhibitory activity against RAF dimers. BGB-283’s increased inhibitory activity  against

RAF dimers may potentially address resistances associated with  increased RAF dimer  formation
in response to treatment with first-generation BRAF inhibitors. As noted  above, most known
molecular mechanisms of resistance to RAF inhibitors induce RAF dimerization. As  such,
BGB-283’s ability to inhibit RAF dimers and target disregulated MAPK pathways resistant to
first-generation BRAF inhibitors could result in a  clinically  significant effect.

(cid:129) Increased activity in KRAS/NRAS mutated cancers. We believe that BGB-283’s RAF dimer  activity
could translate into anti-tumor activity in KRAS/NRAS mutated cancers. Anti-tumor activities
were observed in preclinical KRAS/NRAS mutant cancer  models in vivo.

(cid:129) Increased inhibitory activity against EGFR. BGB-283 has demonstrated inhibitory activity against
EGFR. The reported response rate of vemurafenib in BRAF V600E colorectal cancer is only
5%. Two independent studies suggested that  EGFR feedback activation could be one  of the
main mechanisms of the observed resistance  to  first-generation BRAF inhibitors. BGB-283  has
demonstrated good EGFR inhibitory activity  in  both in vitro and in vivo preclinical models.
BGB-283’s activity against EGFR may help address  the EGFR feedback activation observed in
BRAF V600E colorectal cancer tumors.

33

(cid:129) Differentiated resistance profile. BGB-283 has shown inhibitory activity against RAF dimers. An

increase in RAF dimers has been observed to be a major resistance mechanism to first-
generation BRAF inhibitors. A differentiated  resistance  profile has  been observed  in preclinical
models for BGB-283.

Summary of Clinical Results

Initial analysis of data from these trials suggests that BGB-283 is well-tolerated with a favorable

safety profile. We presented initial clinical  data from our Phase  1 clinical  trial of BGB-283 in  patients
with BRAF or KRAS/NRAS-mutated cancers at the 2016 American Association  for Cancer  Research
annual conference. As of January 31,  2016, the  data  cutoff  date, among  31 advanced solid  tumor
patients, the most frequent treatment-related  adverse events, or  TRAE, were fatigue (52%),
thrombocytopenia  (39%), decreased appetite (39%),  hand-foot  syndrome (35%), dermatitis
acneiform (32%) and hypertension (32%). The most frequent treatment-related  grade 3/4  AEs included
thrombocytopenia  (13%), fatigue (10%)  and liver enzyme elevation (10%).

We  have achieved  proof-of-concept in  a range  of  cancers including those  with KRAS and  BRAF
mutations. At the  time of the data cutoff,  among  29 patients enrolled  in the dose-escalation phase of
the trial evaluable for efficacy, one melanoma patient with BRAF  V600E mutation had a CR, one
endometrial cancer patient with KRAS  mutation and one thyroid cancer patient with BRAF V600E
mutation had a PR, and 15 patients  had an  SD, including  one  NSCLC  patient  with KRAS mutation
with a transient PR or durable SD. As  of  January 31,  2016,  15 patients  had remained on  treatment for
over six months, and the patient with CR had  ongoing  treatment for 342 days, and  the two  patients
with PR had received treatment for 455 days and 574+ days (ongoing),  respectively. When assessed  by
underlying mutations, of six evaluable patients with the BRAF V600E mutation, there was  one  CR,  one
PR and four SDs. Of three evaluable patients with  BRAF non-V600E mutation, there were two SDs.
Of 20  evaluable patients with KRAS/NRAS  mutations, there was  one confirmed PR  and nine SDs.

We  have also initiated a dose-escalation trial in  China. The  goal of the study is to determine dose,
exposure, safety and tolerability, and  efficacy. We observed  more frequent grade 3/4 thrombocytopenia
in the China trial (seven out of 24 patients) compared to the Australia and New Zealand  trial  (eight
out of 105 patients).

We  expect to present data from the Phase 1 dose-expansion study of  BGB-283 in patients with
BRAF or KRAS/NRAS mutated solid  tumors  in an oral presentation on  April 2  during  a Clinical Trials
Plenary Session at the 2017 American  Association  for Cancer  Research Annual Meeting.

In March 2017, we regained the worldwide rights to BGB-283 after Merck KGaA,  Darmstadt
Germany informed us that it will not  exercise the  Continuation Option in its former  exclusive  license to
commercialize and manufacture BGB-283  outside of China.  The agreement with Merck KGaA,
Darmstadt Germany is further detailed in  ‘‘—Collaboration  with Merck  KGaA, Darmstadt Germany.’’

Our Preclinical Programs

Our proprietary cancer biology platform has also  allowed us  to  develop several preclinical-stage
drug candidates in potentially important  targeted areas.  These currently consist of targeted therapies
and immuno-oncology agents including a PD-L1 monoclonal antibody, an additional RAF dimer
inhibitor, a TIM-3 cell surface protein monoclonal antibody, and  a BTK  inhibitor  for non-oncology
indications. We anticipate advancing one  or more of our preclinical assets into the clinic in the next
12 months. We believe we have the opportunity to combine  our PD-1  monoclonal antibody with other
clinical-stage and preclinical candidates  in our pipeline portfolio to target multiple points  in the cancer
immunity cycle. We also seek to develop companion diagnostics that will help identify patients that are
most likely to benefit from the use of our drug candidates.

Collaboration with Merck KGaA, Darmstadt Germany

BGB-283

On May 24, 2013, we entered into license  agreements with Merck KGaA, Darmstadt  Germany,

which  we amended and restated on December 10, 2013 and which we  refer to respectively as the
Ex-PRC BRAF Agreement and PRC  BRAF Agreement. On October  1, 2015 and December 3, 2015,
we further amended the Ex-PRC BRAF Agreement. Pursuant to the Ex-PRC BRAF Agreement  and
PRC BRAF Agreement (a) we granted to Merck KGaA, Darmstadt Germany an exclusive license
under certain of our intellectual property  rights to develop and manufacture, and, if Merck KGaA,
Darmstadt Germany exercised its Continuation Option  (described  below), to commercialize and
manufacture our compound BGB-283,  and any  other compound covered by the same  existing patent
rights with primary activity to inhibit  wildtype or  certain mutant BRAF,  or the Licensed BRAF
Inhibitors, in all countries of the world  excluding The People’s Republic of China, which  we refer to as
the Ex-PRC Territory, and (b) Merck KGaA,  Darmstadt  Germany granted us  an exclusive license  under
certain of its intellectual property rights  to develop, manufacture and  commercialize  the Licensed
BRAF Inhibitors in The People’s Republic of China, which we refer to as the PRC Territory, subject to
the non-compete restrictions discussed  below.

Under the Ex-PRC BRAF Agreement,  Merck KGaA, Darmstadt Germany had the option to
continue such agreement and obtain the  exclusive commercialization  rights described above in the
Ex-PRC Territory, which we refer to as the Continuation Option, by notifying us of  that  election within
60 days following its receipt of the final  reports for the last of certain pre-specified Phase 1 clinical
trials that we retained the responsibility  to perform. In March 2017, Merck KGaA, Darmstadt Germany
informed us that it will not exercise the Continuation Option,  and  thus  the Ex-PRC BRAF Agreement
has terminated in its entirety except  for certain provisions that will survive the  termination.

Further, pursuant to the PRC BRAF Agreement, Merck KGaA, Darmstadt Germany  has an
exclusive right of first negotiation to  acquire exclusive commercialization rights under  the BGB-283
BRAF program in the PRC Territory on terms to be mutually agreed in  the event we seek to license
our  intellectual property rights to a third  party therein.

Under the Ex-PRC and PRC BRAF Agreements,  in December 2013, we received  $13 million in

non-refundable payments. As of December 31, 2016, we have received  $9 million in  milestone
payments. We are eligible to receive additional $14 million in payments upon the  successful
achievement of pre-specified clinical milestones in  the PRC Territory.

We  are required to pay Merck KGaA,  Darmstadt Germany a high single-digit royalty  on aggregate

net sales of Licensed BRAF Inhibitors in  the PRC Territory.

The term of the PRC BRAF Agreement  continues unless  terminated as  permitted by either party.
Under the PRC BRAF Agreement, Merck KGaA has the  right to terminate due to our uncured breach
or voluntarily upon prior written notice. We have the  right to terminate  the  PRC  BRAF Agreement
due to Merck KGaA’s uncured breach or for any  challenge brought against  our licensed  patent  rights.

BGB-290

On October 28, 2013, we entered into  license agreements  with Merck KGaA,  Darmstadt Germany,

which  we refer to respectively as the  Ex-PRC PARP  Agreement and  the PRC PARP Agreement,
pursuant to which (a) we granted to  Merck  KGaA, Darmstadt Germany an exclusive license under
certain of our intellectual property rights to develop and manufacture, and, if Merck KGaA, Darmstadt
Germany exercised a continuation option, to commercialize  and manufacture our compound BGB-290
and any other compound covered by  the  same existing patent rights  with primary activity to inhibit
PARP 1, 2 or 3 enzymes, or the Licensed  PARP  Inhibitors, in the  Ex-PRC Territory, and  (b) Merck
KGaA, Darmstadt Germany granted us an exclusive license  under  certain of its intellectual property
rights to develop, manufacture and commercialize  the Licensed PARP Inhibitors in the  PRC Territory.

35

On October 1, 2015, pursuant to a purchase of rights  agreement, we repurchased all of Merck KGaA,
Darmstadt Germany’s rights under the  Ex-PRC PARP Agreement,  in consideration for, among other
things, a one-time payment of $10 million  and reduction  of future milestone payments  we were eligible
for under the PRC PARP Agreement.  In  connection  with that  repurchase,  we also  agreed to provide
Merck KGaA, Darmstadt Germany with  global access to our clinical PARP supplies,  including
BGB-290, for its combination trials, during the option period. The Ex-PRC PARP Agreement  was
terminated, except for certain provisions  therein  that are needed to effectuate  the continuation of the
PRC PARP Agreement, including those  provisions that were  required in the event  that  Merck KGaA,
Darmstadt Germany exercised its PRC  Commercialization  Option (described below).

Pursuant to the PRC PARP Agreement, if we fail  to  achieve  national priority project status in the
PRC Territory under its 12th or 13th five-year  plan with respect to our BGB-290 PARP  program in  the
PRC Territory by July 28, 2017, Merck  KGaA,  Darmstadt  Germany can exercise its option  to  acquire
exclusive commercialization rights under  the  BGB-290 PARP  program in  the PRC Territory,  which we
refer to as the PRC Commercialization Option. If, however, we  do achieve national  priority by July 28,
2017, Merck KGaA, Darmstadt Germany only has a right  of first negotiation to acquire exclusive
commercialization rights under the BGB-290  PARP program  in the PRC  Territory in the  event we  seek
to license our intellectual property rights to a third party therein.

Under the Ex-PRC and PRC PARP Agreements, in November 2013  we received $6 million in
non-refundable payments and in 2014 $9  million  in milestone payments.  We are  eligible to receive up
to $7 million and $2.5 million, respectively, in payments upon the  successful achievement  of
pre-specified clinical and regulatory milestones in the  PRC Territory.  In addition, if Merck  KGaA,
Darmstadt Germany exercises the PRC  Commercialization Option, Merck KGaA, Darmstadt Germany
is required to pay us a $50 million non-refundable payment upon  such exercise, and we  are eligible for
a $12.5 million milestone payment upon the successful  achievement of a certain additional  regulatory

Regulatory Framework and Structural  Advantages  of Being a  China-Based Research  and Development

Organization

We  believe that basing our research and development effort in China offers  important  regulatory

advantages that differentiate us from  most  multinational  biopharmaceutical and  biotechnology
companies. These advantages include  the following:

(cid:129) Potential for more rapid approval in  the world’s second  largest commercial market, China, due
to a separate regulatory framework for locally developed drug candidates.  This pathway  to
approval creates the potential for our drug candidates to be first-in-class locally and  to  obtain
approval in China prior to ex-China developed  candidates. By  developing our  compounds
preclinically and manufacturing them  in China, we  have the ability to seek product approval
from the CFDA as a domestic Category 1 drug.  This  domestic Category  1 designation allows us
to use a distinct route for bringing our  products to market compared to the Category 5
regulatory process available to multinational companies with drugs  approved for marketing  by
major foreign drug regulatory authorities,  such as the  FDA  or EMA. We believe the Category 1
regulatory pathway will allow us to provide patients in China more rapid  access to safe and
effective cancer therapies.

36

(cid:129) The opportunity to supplement and accelerate global  clinical  development  by  accessing the

Category 1 China local regulatory path for locally developed drug candidates  to  enable more
rapid clinical trial enrollment from a pool of approximately 20—25% of  the world’s cancer
patients. The prevalence rates for some cancers, such as lung, gastric, hepatic and esophageal
are higher in China, and for others, such as breast and cervical, are lower.

(cid:129) Currently, many global standard-of-care therapies are  not  approved or available in China,

resulting in a significant need for innovative therapeutics with strong  efficacy and  safety profiles.
As a result, we believe there is a higher likelihood that drug candidates that have demonstrated
proof-of-concept in the clinic and become qualified for the Category  1 regulatory pathway  will
receive regulatory approval in China.

We  believe our strategy and approach is aligned  with the  Chinese government’s policies, and we
intend to continue to work with local  authorities to bring  innovative therapeutics  to  patients  in China
as quickly as possible.

In August 2015, the Chinese State Council, issued a statement, Opinions on reforming the review
and approval process for pharmaceutical products and  medical  devices that contained several potential
policy changes that could benefit the pharmaceutical industry:

(cid:129) A plan to accelerate innovative drug  approval with a special  review and approval process, with  a
focus on areas of high unmet medical needs, including  drugs  for HIV, cancer, serious infectious
diseases,  orphan diseases and drugs on national  priority lists.

(cid:129) A plan to adopt a policy which would  allow companies to act as  the marketing authorization

holder and to hire contract manufacturing organizations  to produce drug products.

(cid:129) A plan to improve the review and  approval of clinical trials, and to allow companies  to  conduct
clinical trials at the same time as they are in other countries and encourage local clinical trial
organizations to participate in international multi-center clinical trials.

In November 2015, the CFDA released Circular Concerning Several Policies on Drug Registration

Review and Approval, or the No. 230 Circular, which further clarified the following policies potentially
simplifying and accelerating the approval process  of  clinical trials:

(cid:129) A one-time umbrella approval procedure allowing approval  of all phases of a  new drug’s  clinical
trials at once, rather than the current phase-by-phase  approval procedure, will be adopted for
new drugs’ clinical trial application.

(cid:129) A fast track drug registration or clinical trial approval pathway will be available for the following

applications: (1) registration of innovative new drugs treating HIV, cancer, serious infectious
diseases and orphan diseases; (2) registration of pediatric drugs; (3) registration of  geriatric
drugs and drugs treating China-prevalent diseases; (4) registration of drugs sponsored by
national science and technology grants; (5) registration of  innovative drugs using advanced
technology, using innovative treatment methods, or having distinctive clinical benefits;
(6) registration of foreign innovative drugs to be manufactured locally in China; (7) concurrent
applications for new drug clinical trials which are already approved  in the United  States or
European Union or concurrent drug registration applications for drugs which  have applied for
marketing authorization and passed onsite inspections in  the United States or European Union
and  are manufactured using the same production  line in China;  and  (8) clinical trial applications
for drugs with urgent clinical need and patent expiry within three  years,  and  marketing
authorization applications for drugs with urgent clinical need and patent expiry  within one year.

37

In February 2016, the CFDA released  the Opinions on Priority Review and Approval  for Resolving

Drug Registration Applications Backlog, which further clarified the following policies  potentially
accelerating the approval process of certain  clinical trials  or drug registrations which may benefit  us:

(cid:129) A fast  track drug registration or clinical trial approval pathway will be available for the following
drug registration applications with distinctive  clinical benefits: (1)  registration  of  innovative drugs
not sold within or outside China; (2) registration  of innovative drug transferred to be
manufactured in China; (3) registration of drugs using  advanced technology,  using innovative
treatment methods, or having distinctive treatment advantages;  (4) clinical trial applications for
drugs with patent expiry within three years, and marketing authorization applications  for drugs
with patent expiry within one year; (5)  concurrent applications for new drug clinical  trials which
are already approved in the United States or  European Union, or concurrent drug  registration
applications for drugs which have applied  for marketing  authorization and passed onsite
inspections in the United States or European Union and are manufactured  using  the same
production line in China; (6) traditional Chinese medicines (including ethnic medicines) with
clear position in prevention and treatment of serious  diseases; and (7) registration  of new drugs
sponsored by national key technology projects or national key development projects.

(cid:129) A fast  track drug registration approval pathway will be available for the following drugs

registration application with distinctive clinical  benefits for prevention  and  treatment of HIV,
phthisis, virus hepatitis, orphan diseases, cancer, children’s  diseases,  and geriatrics.

In March 2016, the CFDA released a  circular, CFDA Announcement on Reforms of Pharmaceutical

Registration Classification, which outlined the re-classifications of drug applications. Under the new
categorization, innovative drugs that  have not been approved  either in  or outside  China remain
Category 1, while drugs approved outside  China seeking marketing approval in China  are now
Category 5.

The CFDA is soliciting public opinions on detailed  policies  regarding  fast track clinical trial

approval and drug registration pathway, and we expect that the CFDA review  and approval  process  will
improve over time.

Regulatory Framework for Novel Drugs in China

The CFDA categorizes domestically-manufactured  innovative drug  applications as Category 1 and

imported innovative drug applications as Category 3, until a  recent CFDA announcement issued on
March 4, 2016 which reclassifies imported drug applications into Category 5.

Most Chinese companies’ applications for innovative drugs are filed in  Category  1 if the drug has
not already been approved by the FDA or EMA. Most multinational pharmaceutical  companies’ drug
registration applications are filed in Category  5.

Under the current regulations, these two categories have  distinct approval  pathways as discussed

below.

Domestic Innovative Drug Registration Process

For domestically manufactured innovative drug  applications, companies are required to obtain
approval of a Clinical Trial Application before conducting Phase 1 clinical trials in  China. The domestic
innovative drug registration pathway has a fast track review and approval mechanism if the drug
candidate is on a national priority list.

Imported Innovative Drug Registration Process

For a drug that has received marketing approval in other  countries, but is not yet  approved in

China, in order to market an imported drug in China, companies must  apply for an Import Drug

38

License, or IDL, after the drug has received marketing approval and a  Certificate  of  Pharmaceutical
Product, or CPP, from a major foreign drug  regulatory authority, such as the  FDA or  EMA. Compared
with the domestic innovative registration process, the imported innovative drug registration  process is
more complex.

The first step in the process after receipt of a CPP  is to obtain approval of a Clinical Trial
Application to conduct registration studies.  A pharmacokinetic study in Chinese subjects  is also
required. Once this study is completed, the applicant must submit the clinical data package to the
CFDA along with other required information  for the  issuance  of  an IDL. The IDL registration  process
together with clinical trials have typically taken more than five years from the receipt  of foreign
marketing approval.

Currently, the most common strategy  for multinational  companies  is using multi-regional clinical

trial, or MRCT, data to support IDL  approval. Companies  can apply to conduct these  MRCTs prior to
receiving global regulatory approval, with  China  as a subset within a broader MRCT.  However, these
MRCTs are often not designed in a way  that accounts  for the  unique characteristics of the Chinese
patient population and local standards of  care. If the  MRCT data  does not meet  the CFDA’s
registration requirements, the company  may be required to conduct additional  local clinical trials that
can potentially delay market access in China for imported drugs by an additional  three to four years.

The Chinese State Council and the CFDA have recently  issued  several statements and circulars

aimed at improving and accelerating the  new drug  approval process in general. These  include the
August 2015 statement issued by the Chinese State Council, Opinions on reforming the review and
approval  process for pharmaceutical products  and medical devices ; the November 2015 CFDA No. 230
Circular, Circular Concerning Several Policies on Drug Registration Review  and Approval ; February 2016
CFDA Circular, Opinions on Priority Review and Approval  for Resolving Drug Registration Applications
Backlog ; and  the March 2016 CFDA No. 51 Circular, Announcement on Reforms of Pharmaceutical
Registration Classification issued by the CFDA on March 4, 2016.  In  the March 4,  2016 CFDA
announcement, the drugs approved outside China seeking marketing approval in  China are  now called
Category 5. We believe these new regulatory  initiatives will likely  accelerate the approval  process for
new drugs, including those marketed in  other countries  but not yet  in China. However, how and when
this approval process will be changed is  still subject to further policies  to  be issued  by  the CFDA  and is
currently uncertain.

Commercial Opportunities in China

In addition to the structural and clinical advantages afforded to us  by basing our  research  and
development operations in China, we see  an attractive and  growing commercial oncology opportunity in
our home market.  We continue to retain  commercial rights in China for all  four of our clinical
programs and all preclinical programs.

China’s Pharmaceutical Market

China’s pharmaceutical market has grown robustly and replaced Japan  as the second largest

pharmaceutical market in 2013, according  to  IMS Health. According to the IMS  Market Prognosis
published in March 2015, the Chinese  pharmaceutical  market was  $109 billion  in 2014, as  compared to
a $373 billion U.S. pharmaceutical market  in  2014, and is expected to grow at  a compound annual
growth rate, or CAGR, of 9.3% over the  next five years reaching $171 billion by 2019. The growth  of
the Chinese pharmaceutical market is attributable, in particular to:

(cid:129) An aging population, modern diet, lack  of exercise and  environmental issues that are  increasing

the prevalence of chronic diseases.

(cid:129) Increases in disease awareness, diagnostics  and  treatment rates.

(cid:129) The continuous and rapid increase of personal disposable income and the establishment of basic

national health insurance coverage;  making health care accessible  to  more  patients.

China provides an opportunity to access largely untapped clinical  trial pools and develop drugs for

a population for whom global standard of care therapies are not available.  China has  nearly a  quarter
of the world’s cancer patient population and one third to half of cancer patients  in certain tumor types
are in China, such as lung, gastric, liver and esophageal  cancers.

The oncology market in China is estimated  to  have grown at a CAGR of 24% in the last  decade

through 2014. In recent years, sales of targeted therapy drugs in  retail channels  have increased  rapidly.
Although expensive targeted therapy  drugs are not included  in basic national  healthcare insurance and
have historically had very little coverage by provincial insurance plans, the targeted therapy drug
market has continued to grow rapidly despite being an out-of-pocket market. This  growth is  attributable
to patients’ needs, newly launched drugs  and  patient’s ability to pay for drugs not covered by insurance.

Introduction of Reimbursement

The Chinese State Council requires central and provincial authorities across  the PRC to promote a

medical insurance program for major illnesses.  By the  end by 2015, all  urban and rural residents
covered by basic medical insurance programs  are required to be covered by  the insurance program for
major illnesses, according to a Chinese State Council policy issued on July  28, 2015. As a complement
to basic insurance programs, this program  is required to cover at least 50% of the medical cost
incurred in connection with treating major illnesses and is supplemental  to basic insurance programs.
The Chinese State Council now requires provincial authorities to increase  reimbursement rates over the
next three years.

According to the PRC Central Government’s guidance issued in March 2015, each province will

decide which  drugs to include in its provincial major  illness  reimbursement lists and  the percentage of
reimbursement, based on local funding. For example, Zhejiang  province, located in the  Yangtze river
delta area with a population of 55 million, announced its provincial  major illness drug reimbursement
list in early 2015. The list includes 31 high-priced drugs, 15  of which are targeted therapy  agents for
cancer, including Glivec, Ireesa, Erbitux, Herceptin,  and  Rituxan. Although  it will take three years to
establish comprehensive national coverage,  the affordability of  the high-priced,  novel cancer agents to
Chinese patients could improve significantly.

41

On February 23, 2017, the Ministry of Human Resources and Social  Security released the
long-expected new version of the national reimbursement drug list, or NRDL. The NRDL  has been
expanded by 16.7%, with covered drugs  increased from 2,172 in the 2009  version to 2,535, including
1,297 chemical / biological drugs (51.1% of  total,  vs.  1,140 in 2009) and 1,238  traditional  Chinese
medicines / ethnic drugs (48.9% of total,  vs. 1,032 in 2009).  Several targeted oncology drugs are  on the
list, including icotinib, dasatinib, gefitinib, and imatinib. NRDL inclusion could be a  significant
opportunity over the long term an improve the market penetration for the drugs being newly included.

Our Mission and Strategy

Our mission is to become a global leader  in the discovery and  development of innovative,

molecularly targeted and immuno-oncology drugs for the treatment of cancer. To  achieve  our  mission,
we intend to pursue the following strategies:

(cid:129) Rapidly advance our pipeline programs through global development. In the next 12 months, we
plan  to make significant advances within  our clinical-stage pipeline. We have initiated global  and
China pivotal trials with BGB-3111, and moved our three other clinical-stage  drug  candidates
into the clinic in China and into the dose-expansion phases of their respective clinical trials in
other parts of the world. We will continue to enroll multiple expansion cohorts and significantly
increase the number of sites globally participating in  these trials. We plan to present data from
these trials at medical conferences in 2017. We  also have a robust pipeline of  preclinical
programs and are planning to advance  one  or more of these programs into the clinic in the next
12 months.

(cid:129) Pursue  global development of combination therapies. We believe our ownership of both

molecularly targeted and immuno-oncology drugs puts us  in  an advantageous position to develop
potentially best-in-combination or first-in-combination  therapies that could produce high  rates of
more durable responses in patients. We have four clinical-stage, independently discovered drug
candidates in important and combinable  molecularly  targeted  and immuno-oncology drug classes
including BTK inhibitor, PD-1 inhibitor, PARP inhibitor and RAF dimer inhibitor. We believe
that we are one of only two companies  today to wholly own both a  clinical-stage BTK inhibitor
for cancer treatment and PD-1 inhibitor and one of the  few companies to have discovered, and
advanced to clinical stage, a PARP inhibitor and PD-1  inhibitor or  a BRAF inhibitor and PD-1
inhibitor for use as combination therapies.  In addition to monotherapy trials, we have initiated
and are planning combination trials using  our wholly-owned drug candidates as well  as third-
party agents. For BGB-3111, in January 2016 we  initiated a  combination clinical trial with the
anti-CD20 antibody, obinutuzumab, and the trial is currently in the dose-expansion phase. In
June 2016, we initiated a combination  clinical trial with  BGB-A317 for the treatment  of various
B-cell malignancies. For BGB-290, in February 2016, we  initiated  a combination clinical trial
with BGB-A317. We plan to present data from these combination trials at medical conferences
in 2017.

(cid:129) Continue to use our cancer biology platform  to discover additional candidates with  best-in-class

characteristics and potential for use in rational combinations. We plan to use our cancer
biology platform to discover additional drug  candidates with the potential to be best-in-class
monotherapies and also important components of  multiple-agent combination regimens. In the
last six years, we have been successful in discovering four  clinical  stage and several promising
preclinical drug candidates. By further  investing in and improving our  cancer biology platform,
we expect that the platform will continue to help  us  select relevant drug targets, identify
potential best-in-class drug candidates and  develop  regimens for rational drug combinations.

(cid:129) Bring transformative oncology therapeutics to our  home market  in China. We are committed to
addressing the needs of cancer patients in our  home market.  China is one of the  largest and

42

fastest growing markets for cancer drugs worldwide,  representing  approximately  20–25% of the
world’s cancer population and an even greater proportion in lung, liver, and gastric  cancers.
Because many global standard-of-care therapies are  not  currently approved and available in
China, there is a significant unmet need  for  innovative cancer  drugs  for patients  who are naive
to such treatments. In addition, focusing on  cancer types of high  prevalence in China  will aid
our  global development efforts in these indications. We  have initiated clinical trials in China for
each  of our four clinical-stage drug candidates to develop them through  the locally developed,
Category 1 registration pathway. We plan to pursue accelerated development, single-arm
registration studies and brief dose-escalation studies  in China. We  also  strive to have  our drug
candidates selected and listed as national priorities. The ability to launch  our cancer  drugs in our
home market, which has a large patient population, will help us  establish broad safety and
efficacy profiles for each drug, enabling us  to  build a full  portfolio for future drug combinations.

(cid:129) Maintain our culture as we grow our business globally. We believe our science-driven,

cooperative and non-hierarchical culture  is a  key  strength of our organization and will continue
to be instrumental to our success. As an innovative biotechnology company with  research
facilities in China, we have been able to attract an internationally  trained research team.  Many
members of our team moved back to China  from other countries to join us because  they share
our  goals of advancing the discovery and  development of drugs in China and of  working with
Chinese clinicians to treat their patients with  innovative and  effective drugs not currently
available to them. We intend to maintain our patient-focused  and research-driven  culture as we
discover and develop new drugs for China and the rest of the world.

(cid:129) Retain the value of our pipeline in our core  focus area of  oncology. We currently retain all

worldwide development and commercial rights for  our BTK, PD-1  and preclinical therapeutics.
In addition, we have limited collaborations  with Merck KGaA,  Darmstadt  Germany on  our
BGB-290 and BGB-283 programs. We intend to protect  our ability  to  direct global  preclinical
studies  and clinical trials for our drug candidates as  monotherapies  and  combination  therapies
and to maintain exclusive rights in our  home market. However, we may opportunistically
evaluate additional collaboration opportunities  that could  increase the value of our programs by
accessing the expertise or infrastructure of strategic collaborators  or  by developing  drug
candidates with potential applications outside  of  our strategic focus  on cancer.

Intellectual Property

The proprietary nature of, and protection  for,  our  drug candidates and  their methods of  use are  an

important part of our strategy to develop  and commercialize  novel medicines, as described in more
detail below. We have obtained a U.S. patent and filed patent applications in the  United States and
other countries relating to certain of our drug  candidates, and are pursuing additional  patent  protection
for them and for other of our drug candidates and  technologies.  We also rely on trade secrets to
protect aspects of our business that are not amenable  to,  or that  we  do not  consider appropriate for,
patent protection including our manufacturing processes.

Our success will depend significantly on our ability to obtain and maintain patent and other

proprietary protection for our product candidates and other commercially  important  products,
technologies, inventions and know-how,  as well as on our ability to defend and enforce our patents
including any patent that we have or may issue from  our  patent  applications, preserve the
confidentiality of our trade secrets and operate without infringing the valid and enforceable  patents  and
proprietary rights of other parties. We also rely  on know-how,  continuing technological  innovation and
in-licensing opportunities to develop,  strengthen and  support our development programs.

As of March 21, 2017, we own eight  issued U.S.  patents  and eight pending  U.S. patent applications

as well as corresponding patents and  patent applications internationally.  In  addition, we own 13

43

pending international patent applications  under the  Patent Cooperation Treaty, or PCT, which  we plan
to file nationally in the United States and other jurisdictions. With  respect to any  issued patents in the
United States and Europe, we may be entitled to obtain a  patent term extension to extend the patent
expiration date provided we meet the applicable  requirements for  obtaining such patent term
extensions. For example, in the United States, we can  apply for a patent term  extension of up  to  five
years for one of the patents covering  a product once the  product is  approved by the  FDA. The exact
duration of the extension depends on  the time we spend in  clinical  studies as well  as getting  a new
drug application, or NDA, approval from  the  FDA. The patent portfolios for  our  four leading product
candidates as of March 21, 2017 are  summarized below:

(cid:129) BGB-3111. We own one issued U.S. patent, one pending U.S.  patent application, two PCT,

applications, and corresponding patent  applications  in other  jurisdictions directed to BGB-3111,
a small molecule BTK inhibitor, and its use for the treatment  of  hematological malignancies.
The expected expiration for the issued  U.S. patent is 2034, excluding any  additional  term for
patent term extensions. Any patents that may issue from  the currently pending U.S.  patent
applications would be expected to expire in  2034, not including any patent  term adjustments. If  a
U.S. application is filed based on the pending PCT  applications, a patent issuing from  these
applications, if any, would be expected to expire in 2037. We intend  to  pursue marketing
exclusivity periods that are available under regulatory  provisions  in certain countries

(cid:129) BGB-A317. We are the owner of one issued U.S. patent, one pending  U.S.  application, one

pending PCT application, and corresponding pending patent applications  in other  jurisdictions
directed to BGB-A317, a humanized monoclonal  antibody against PD-1, and its use  for the
treatment of cancer. The expected expiration for the issued  U.S. patent is  2033, excluding any
additional term for patent term extensions. Any patent that  may  issue from  the currently
pending U.S. patent application would  be  expected to expire in 2033,  not  including any patent
term adjustments. If a U.S. application  is filed  based on the pending PCT application, a patent
issuing from the application, if any,  would be expected to expire  in 2037.  We intend to pursue
marketing exclusivity periods that are available under regulatory provisions  in certain countries.

(cid:129) BGB-290. We own one issued U.S. patent, one pending U.S.  patent application, and two

pending PCT applications directed to BGB-290,  a small  molecule  PARP1/2 inhibitor,  and its use
for the treatment of cancer, including  glioblastomas and breast cancer. We also own  the
corresponding pending patent applications in other jurisdictions. The  expected expiration for  the
issued U.S. patent is 2031, excluding any  additional term  for  patent term extensions. Any patent
that may issue from the currently pending U.S.  patent application would be expected to expire in
2031, not including any patent term adjustments. If  a U.S.  application  is filed based on the
pending PCT applications, a patent issuing from these applications, if any, would be expected to
expire in 2036 and 2037. We intend to pursue  marketing  exclusivity periods that are available
under regulatory provisions in certain countries.

(cid:129) BGB-283. We own one issued U.S. patent, one pending U.S.  patent application, and two

pending PCT applications directed to BGB-283,  a small  molecule  BRAF  inhibitor, and  its use
for the treatment of cancer, including  BRAF mutated cancers. We also own pending patent
applications in other jurisdictions corresponding to the U.S. patent application. In  addition,  we
plan  to file nationally in the U.S. and other jurisdictions based on the  pending  PCT application.
The expected expiration for the issued  U.S. patent is 2031, excluding any  additional  term for
patent term extensions. Any patent that  may  issue from the currently  pending  U.S. patent
application would be expected to expire in  2031, not including any patent  term adjustments. If a
U.S. application is filed based on the pending PCT  applications, a patent issuing from  these
applications, if any, would be expected to expire in 2036 and 2037. We  intend to pursue
marketing exclusivity periods that are available under regulatory provisions  in certain countries.

44

The term of individual patents may vary based on the countries  in which  they are  obtained.  In

most countries in which we file including  the United States, the term  of  an issued patent is generally
20 years from the earliest claimed filing  date of  a non-provisional patent application in  the applicable
country. In the United States, a patent’s  term may  be  lengthened in  some cases  by  a patent term
adjustment, which extends the term of a patent to account for administrative delays  by  the U.S.  Patent
and Trademark Office, or USPTO, in excess of  a patent applicant’s own delays during the prosecution
process, or may be shortened if a patent is terminally disclaimed  over a  commonly owned  patent  having
an earlier expiration date. In addition,  in certain instances,  a patent term  can be extended  to  recapture
a portion of the term effectively lost as  a  result of the  FDA regulatory review period.  However, the
restoration period cannot be longer than five years and the total patent term  including the  restoration
period must not exceed 14 years following  FDA  approval.

In certain foreign jurisdictions similar  extensions as compensation  for  regulatory delays are also
available. The actual protection afforded  by  a patent varies on  a  claim  by claim and  country  by  country
basis and depends upon many factors, including the type  of patent, the scope of its coverage, the
availability of any patent term extensions or adjustments, the availability  of legal  remedies in  a
particular country and the validity and  enforceability of the patent.

Furthermore, the patent positions of  biotechnology  and  pharmaceutical  products and processes like

those we intend to develop and commercialize are generally uncertain  and involve complex legal and
factual questions. No consistent policy regarding  the breadth of claims  allowed  in such patents  has
emerged to date in the United States.  The scope of patent protection outside the United  States is even
more uncertain. Changes in the patent laws or in  interpretations of patent laws in  the United  States
and other countries may diminish our ability  to  protect our inventions, and enforce our intellectual
property rights and more generally, could  affect the  value of intellectual  property.

Additionally, we cannot predict the breadth of claims that  may  be  allowed  or enforced  in our

patents or in patents owned by others.  Substantial scientific and commercial research has been
conducted for many years in the areas  in  which we  have focused our development efforts,  which has
resulted in other parties having a number  of issued patents  and pending patent applications relating  to
such areas. Patent applications in the United States and elsewhere are generally  published only after
18 months from the priority date, and the  publication  of  discoveries  in the scientific or patent literature
frequently occurs substantially later than  the date  on which the underlying discoveries were  made.
Therefore, patents and patent applications relating  to  drugs  similar to our current  drug  candidates and
any future drugs, discoveries or technologies we might develop may have  already  issued or been  filed,
which  could prohibit us from commercializing our product candidates. Specifically, we  are aware of
certain U.S. patents owned by Ono Pharmaceutical Co. and  licensed to Bristol-Myers Squibb Co. that
are relevant to our BGB-A317 drug candidate.  We are also aware  of  a U.S. patent owned by
Pharmacyclics, Inc., which was acquired by AbbVie Inc., that  is relevant  to  our  BGB-3111  drug
candidate, and certain U.S. patents owned or  licensed  by KuDOS Pharmaceuticals, Ltd., which  was
acquired by AstraZeneca PLC, that are relevant to our BGB-290 drug candidate. For  more
information, see ‘‘Item 1A—Risk Factors—Risks Related to Our Intellectual Property.’’

The biotechnology and pharmaceutical industries are characterized by  extensive  litigation regarding

patents and other intellectual property  rights. Our  ability to  maintain and solidify our proprietary
position for our drug candidates and  technology will depend on our  success in obtaining effective
claims and enforcing those claims once  granted. We do not know whether any of the  patent
applications that we may file or license  from others  will  result in the  issuance  of  any patents.  The
issued patents that we own or may receive in  the future,  may be challenged, invalidated or
circumvented, and the rights granted  under any issued patents  may  not  provide us with proprietary
protection or competitive advantages  against  competitors with similar technology. Furthermore, our
competitors may be able to independently  develop  and  commercialize  similar drugs or  duplicate  our
technology, business model or strategy  without infringing our  patents. Because of the extensive time

45

required for clinical development and  regulatory  review of  a  drug we may  develop,  it is possible that,
before any of our drug candidates can be commercialized, any  related patent may expire or remain in
force for only a short period following  commercialization,  thereby  reducing  any advantage of any such
patent.

We  may rely, in some circumstances, on trade secrets and unpatented know-how  to  protect aspects

of our technology. However, trade secrets can be difficult to  protect. We  seek to protect our
proprietary technology and processes, in  part, by entering into confidentiality agreements  with
consultants, scientific advisors and contractors  and  invention  assignment  agreements with our
employees. We also seek to preserve  the integrity and confidentiality of our  data  and trade  secrets  by
maintaining physical security of our premises and physical  and electronic security of our information
technology systems. While we have confidence in these individuals, organizations and systems,
agreements or security measures may  be  breached and we  may not have adequate remedies for any
breach. In addition, our trade secrets  may  otherwise become known or be independently  discovered by
competitors. To the extent that our consultants,  contractors  or  collaborators use  intellectual property
owned by others in their work for us,  disputes may  arise as to the rights  in related or  resulting
know-how and inventions.

Our commercial success will also depend in  part on not infringing  the proprietary  rights of other
parties. The issuance of any patent by others with claims covering or related to aspects of our product
candidates would require us to alter  our development  or commercial strategies, redesign our  drug
candidates or processes, obtain licenses  or cease  certain activities. Such licenses may  not  be  available
on reasonable commercial terms or at  all,  which could  require us to cease development or
commercialization of our product candidates. In addition, our breach of any license agreements or
failure to obtain a license to proprietary  rights that  we may require to develop or commercialize our
drug candidates would have a material adverse impact on us. If others  have prepared and  filed patent
applications in the United States that  also  claim  technology to which  we  have  filed patent applications,
we may have to participate in interference, derivation or other proceedings in  the USPTO  to  determine
issues such as priority of claimed invention or validity of such patent applications as well  as our own
patent applications and issued patent.

For more information on these and other  risks related to intellectual property, see ‘‘Item  1A—Risk

Factors—Risks Related to Our Intellectual Property.’’

Additionally, we currently use a number of  unregistered trademarks and are  seeking trademark

protection in jurisdictions where available  and  appropriate. We currently have  applications pending  in
China for BeiGene, and our corporate  logo.

Competition

Our industry is highly competitive and subject to rapid and significant change. While we believe
that our development and commercialization experience, scientific  knowledge and industry relationships
provide us with competitive advantages, we  face competition  from pharmaceutical, medical device  and
biotechnology companies, including specialty pharmaceutical companies,  and generic  drug  companies,
academic institutions, government agencies and research institutions.

BGB-3111 Competition

We  are developing BGB-3111, a highly selective small  molecule  covalent  BTK inhibitor, for a

variety of B-cell malignancies, either  as a monotherapy or in combination with  other therapies.

46

Janssen/AbbVie’s ibrutinib (IMBRUVICA) is  one  of the currently approved drugs used for the
treatment of B-cell malignancies, including patients with MCL who have received at  least one prior
therapy, patients with CLL, CLL patients with 17p deletion, and WM. It has also recently been
approved by the FDA for the treatment of  patients with relapsed/refractory MZL who require systemic
therapy and have received at least one prior anti-CD20-based therapy.

Multiple ongoing Phase 3 trials are currently being conducted for ibrutinib as a monotherapy or in

combination with chemotherapeutics  or target therapeutics in  various B-cell malignancies, including
CLL, MCL, WM, FL, DLBCL and MZL.  In addition, we  are aware of other  BTK inhibitors in clinical
development for oncology indications, including AstraZeneca’s acalabrutinib  (ACP-196)  currently  in
Phase 3, Ono/Gilead’s tirabrutinib in  Phase 2,  Sunesis’ SNS-062 in Phase 1b/2, Merck KGaA,
Darmstadt Germany’s M7583 in Phase  1, and Zhejiang Daoming  BioPharma’s DTRMWXHS-12 in
Phase 1.

BGB-A317 Competition

Three anti-PD-1 or PDL1 monoclonal antibody drugs, Merck’s  pembrolizumab (Keytruda),  Bristol-
Myers Squibb’s nivolumab (Opdivo),  and Roche’s atezolizumab (Tecentriq) have  been approved  by  the
FDA.

A number of companies are currently conducting ongoing  clinical trials involving an  anti-PD-1 or

anti-PD-L1. Three anti-PD-L1 antibody drugs,  AstraZeneca/Celgene’s durvalumab  and Pfizer/Merck
KGaA, Darmstadt Germany’s avelumab, together with  anti-PD-1 antibodies,  Merck’s pembrolizumab,
Bristol-Myers Squibb’s nivolumab and  Regeneron’s REGN2810, are currently engaged in a  number of
Phase 2/3 trials, for treatment of multiple cancers, such as NSCLC, HNSCC, bladder  cancer, triple-
negative breast cancer, non-Hodgkin’s  lymphoma and melanoma, advanced  cutaneous squamous cell
carcinoma. Several new anti-PD-1 antibodies have  started Phase 1/2 trials,  including AstraZeneca’s
MEDI0680, and Novartis’ PDR001, Tesaro’s TSR042 and Incyte / Hengrui’s  SHR-1210. In China,
anti-PD-1 antibody SHR-1210 from Jiangsu  Hengrui is in Phase 2/3  monotherapy trial  in hepatocellular
carcinoma and several Phase 1/2 studies  in solid tumors  such as  melanoma as  well as ongoing Phase 1/2
combination trial with apatinib for hepatocellular carcinoma  and gastric cancer. Other anti-PD-1
antibodies in clinical development by  a  domestic company include  Junshi’s  JS001 and  Innovent Bio’s
IBI308 and are undergoing multiple Phase 1  studies in solid tumors in  China.

Many of our competitors have significantly greater financial, technical  and human  resources  than
we have. Mergers and acquisitions in  the pharmaceutical, medical device  and biotechnology industries
may result in even more resources being  concentrated among a smaller number of our competitors.
Our commercial opportunity could be reduced  or eliminated  if our competitors  develop  or market
products or other novel therapies that are more effective,  safer or less costly  than our current  or future
drug candidates, or obtain regulatory  approval  for their products more rapidly than we may obtain
approval for our drug candidates. Our  success will  be  based in part on our ability to identify,  develop
and manage a portfolio of drug candidates that are safer  and more effective than competing products.

BGB-290 Competition

AstraZeneca’s olaparib (LYNPARZA)  is approved  by  the FDA  for treating  patients with

deleterious or suspected deleterious  germline BRCA mutated, or gBRCAm advanced ovarian cancer
who have been treated with three or  more  prior lines of chemotherapy  or a combination of
chemotherapies. It is approved by the  EMA as  a maintenance  treatment for patients with  platinum-
sensitive relapsed BRCA-mutated, germline  and/or somatic, high  grade serous epithelial ovarian,
fallopian tube, or primary peritoneal  cancer who are in  CR  or PR to platinum-based chemotherapy.  In
addition, the FDA recently approved  Clovis’ rucaparib (RUBRACA)  for  treatment of patients with

47

deleterious BRCA mutation, germline  and/or  somatic,  associated advanced ovarian cancer who have
been treated with two or more chemotherapies.

There are a number of companies with ongoing  clinical  trials, including  AstraZeneca, Abbott,

Tesaro and Pfizer. AstraZeneca’s olaparib has been  approved in  gBRCAm  ovarian cancer and is
currently in Phase 3 trials for treatment  of gBRCAm breast cancer, gastric cancer, gBRCAm pancreatic
cancer and other cancers with sBRCAm  or  homologous recombinant repair  associated genetic
mutations. Clovis Oncology’s rucaparib is  currently in Phase 3 trials as a maintenance treatment in
patients with platinum-sensitive, high-grade serous  or endometrioid epithelial ovarian,  primary
peritoneal or fallopian tube cancer and  as a  second  line  treatment in  patients  with metastatic
castration-resistant prostate cancer and  homologous recombination  gene deficiency.  In November 2016,
Tesaro submitted a NDA to the FDA  for niraparib as  a second-line maintenance therapy in  patients
with ovarian cancer. Niraparib also is currently in  Phase 3  trials as  a  first-line maintenance treatment in
patients with ovarian cancer with homologous recombination  gene deficiency  following  response  on
front-line platinum-based chemotherapy  and gBRCAm breast cancer.  Pfizer’s talazoparib is currently in
Phase 3 trials for BRCAm breast cancer.  Abbott’s veliparib, in  combination with other  compound(s), is
currently in Phase 3 trials for treatment of  non-small-cell  lung cancer, breast, ovarian cancers  and
glioblastoma multiforme. In China, PARP  inhibitors  in Phase 1 trials by domestic companies  include
Jiangsu Hansoh’s fluzoparib and Jiangxi  Qingfeng’s  SC10914.

BGB-283 Competition

We  are developing BGB-283 as either  a monotherapy  or in combination  with other cancer
therapies for the treatment of cancers with aberrations in the MAPK  pathway including  BRAF
mutations and KRAS/NRAS mutations.

Roche’s vemurafenib (Zelboraf) and Novartis’  dabrafenib (Tafinlar) are two of the currently
approved BRAF inhibitors for treating  late-stage  BRAF V600E/K mutant melanoma. In  addition,  the
combination of dabrafenib and GSK’s  trametinib (Mekinist), an MEK  inhibitor,  is approved in patients
with BRAF V600E/K mutation-positive  metastatic melanoma. We are aware of several other BRAF
inhibitors in clinical development targeting BRAF V600E/K mutated cancers including melanoma,
NSCLC, HCL and thyroid cancer. These BRAF inhibitors include Array Biopharma’s  encorafenib
(LGX818), currently in Phase 3 trials,  and  Takeda’s MLN-2480  (BIIB-024), Daiichi Sankyo’s PLX-8394,
and Roche’s RG-6185, all in Phase 1 trials.

Government Regulation

Government authorities in the United States at  the federal, state and local level  and in  other
countries extensively regulate, among  other things, the research  and  clinical development,  testing,
manufacture, quality control, approval,  labeling, packaging,  storage,  record-keeping, promotion,
advertising, distribution, post-approval  monitoring  and  reporting, marketing, pricing  and export and
import of drug products, such as those  we are developing. Generally, before a new drug can be
marketed, considerable data demonstrating its quality,  safety and efficacy must be obtained, organized
into a format specific to each regulatory authority, submitted for review and approved by the  regulatory
authority.

Drugs are also subject to other federal, state  and  local statutes  and regulations. The process of
obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and
foreign statutes and regulations require the  expenditure of substantial time and  financial  resources.
Failure to comply with the applicable  regulatory requirements at  any time during the  product
development process, approval process or  after approval, may subject  an applicant to administrative or
judicial sanctions.  These sanctions could include, among other  actions, the regulatory  authority’s refusal
to approve pending applications, withdrawal of an  approval, clinical  holds, untitled  or warning letters,

48

voluntary product recalls or withdrawals  from the market, product seizures, total or partial suspension
of production or distribution injunctions,  debarment, fines, refusals of  government contracts, restitution,
disgorgement, or civil or criminal penalties. Any agency  or judicial  enforcement action could have  a
material adverse effect on us.

U.S. Regulation

U.S. Government Regulation and Product  Approval

Government authorities in the United States at  the federal, state and local level  extensively

regulate, among other things, the research, development, testing, manufacture, quality control, approval,
labeling, packaging, storage, record-keeping, promotion, advertising, distribution,  marketing,  export and
import of drug and biological products  such as those we are  developing.  In the  United States, the  FDA
regulates drugs under the Federal Food,  Drug,  and  Cosmetic  Act, or FDCA, and its implementing
regulations, and biologics under the FDCA, its implementing  regulations, and the Public Health  Service
Act, or PHSA, and its implementing  regulations.

U.S. Drug Development Process

The process of obtaining regulatory approvals and compliance  with appropriate federal, state,  local
and foreign statutes and regulations require the  expenditure of  substantial time and  financial resources.
Failure to comply with the applicable  U.S. requirements at  any time during the  product development
process, approval process, or after approval, may subject an applicant  to  administrative or judicial
sanctions. These sanctions could include the FDA’s refusal  to  approve pending  applications,  withdrawal
of an approval, a clinical hold, untitled or warning letters, product recalls, product seizures, total  or
partial suspension of production or distribution,  injunctions, fines, refusals of government  contracts,
restitution, disgorgement or civil or criminal penalties.  The process  required by the  FDA before  a drug
or biologic may be marketed in the United States  generally  involves the following:

(cid:129) completion of preclinical laboratory tests,  animal studies and formulation studies  according to

Good Laboratory Practices, or GLP, and  current Good  Manufacture Practice , or GMP,
regulations;

(cid:129) submission to the FDA of an IND application, which  must become effective before human

clinical trials may begin;

(cid:129) performance of adequate and well-controlled  human clinical trials according  to  Good Clinical
Practice, or GCP, to establish the safety and efficacy of the  proposed product  for its intended
use;

(cid:129) preparation and submission to the FDA of a  NDA for a drug, or a Biologics License

Application, or BLA, for a biologic;

(cid:129) a determination by the FDA within 60 days of its receipt  of  a NDA  or BLA to file  the

application for review;

(cid:129) satisfactory completion of an FDA  inspection  of the manufacturing facility or facilities at which

the product, or components thereof, are produced to assess compliance  with current  Good
Manufacturing Practices, or cGMP;

(cid:129) FDA audits of some clinical trial sites to ensure compliance  with GCPs; and

(cid:129) FDA review and approval of the NDA or licensing of the BLA.

The testing and approval process requires substantial  time, effort and financial resources  and we

cannot be certain that any approvals  for our drug  candidates will  be  granted on a timely basis, if at all.

49

Once a pharmaceutical product drug is identified for development, it enters  the preclinical testing

stage. Preclinical tests include laboratory  evaluations of product chemistry, toxicity,  formulation and
stability, as well as animal studies. An IND sponsor must submit the  results of the  preclinical tests,
together with manufacturing information,  analytical data and any available clinical data or literature, to
the FDA as part of the IND. The sponsor  must  also include a  protocol detailing, among other things,
the objectives of the initial clinical trial,  the parameters to be used in  monitoring safety and the
effectiveness criteria to be evaluated if  the initial clinical trial lends itself  to  an efficacy evaluation.
Some preclinical testing may continue  even  after the IND is submitted.  The  IND automatically
becomes effective 30 days after receipt by  the FDA, unless the FDA raises concerns or  questions
related to a proposed clinical trial and  places the  trial on a clinical hold within that 30-day time period.
In such a case, the IND sponsor and  the FDA must resolve any outstanding concerns  before  the
clinical trial can begin. Clinical holds  also  may be imposed  by the  FDA at any  time before or  during
clinical trials due to safety concerns or  noncompliance, and may be imposed  on all products within a
certain class of products. The FDA also  can impose  partial clinical holds, for example, prohibiting the
initiation of clinical trials of a certain  duration or for a certain  dose.

All clinical trials must be conducted  under the supervision of one or more qualified investigators in

accordance with GCP regulations. These  regulations include the requirement that all research subjects
provide informed consent in writing before their participation in any clinical trial. Further, an
Institutional Review Board, or IRB,  must  review  and approve the  plan for any clinical  trial before  it
commences at any institution, and the  IRB must conduct continuing  review and reapprove the study at
least annually. An IRB considers, among other things, whether the  risks to individuals participating  in
the clinical trial are minimized and are  reasonable in relation to anticipated benefits.  The IRB  also
approves the information regarding the clinical  trial and  the consent form that must be provided to
each  clinical trial subject or his or her legal  representative and  must monitor the clinical trial until
completed.

Each  new clinical protocol and any amendments to the  protocol  must be filed with  the FDA as  an
IND amendment, and to the IRBs for approval. Protocols detail, among other things, the objectives of
the clinical trial, dosing procedures, subject selection and exclusion criteria,  and the  parameters  to  be
used to monitor subject safety.

Human clinical trials are typically conducted  in three  sequential phases that may overlap or be

combined:

(cid:129) Phase 1. The product is initially introduced into a small number  of  healthy  human subjects or

patients and tested for safety, dosage tolerance, absorption, metabolism,  distribution and
excretion and, if possible, to gain early evidence  on effectiveness. In the case  of some  products
for severe or life-threatening diseases, especially  when the  product is  suspected  or known to be
unavoidably toxic, the initial human testing  may be conducted  in patients.

(cid:129) Phase 2. Involves clinical trials in a limited patient  population to identify  possible adverse effects

and safety risks, to preliminarily evaluate  the efficacy of the product for  specific  targeted
diseases  and to determine dosage tolerance and optimal dosage  and schedule.

(cid:129) Phase 3. Clinical trials are undertaken to further evaluate dosage, clinical  efficacy and safety  in
an expanded patient population at geographically  dispersed clinical trial sites.  These clinical
trials are intended to establish the overall risk/benefit relationship of the  product and provide an
adequate basis for product labelling.

We  refer to our Phase 1 program as  dose-escalation and dose-expansion trials.

Progress reports detailing the results  of the  clinical trials  must  be  submitted at  least  annually  to  the

FDA and safety reports must be submitted to the FDA and the investigators  for serious and
unexpected suspected AEs, any clinically  important increase in the rate of a  serious suspected adverse

50

reaction over that listed in the protocol or investigator’s brochure, or any findings  from other studies  or
animal or in vitro testing that suggest a significant risk  in humans exposed to the  product drug. Phase 1,
Phase 2 and Phase 3 studies may not be completed successfully within any specified period, if at  all.
The FDA or the sponsor may suspend  or terminate  a clinical trial  at  any  time on  various grounds,
including a finding that the research  subjects  or patients are  being exposed  to  an unacceptable health
risk. Similarly, an IRB can suspend or terminate  approval of a clinical  trial  at its institution  if the
clinical trial is not  being conducted in accordance  with the IRB’s requirements or  if the  product has
been associated with unexpected serious harm to subjects.

Concurrent with clinical trials, companies usually complete additional animal studies and  must  also

develop additional information about the chemistry and physical characteristics of the product and
finalize a process for manufacturing the  product in  commercial quantities in  accordance  with cGMP
requirements. The manufacturing process must  be  capable of consistently  producing quality batches of
the product drug and, among other things,  the manufacturer must develop methods for testing the
identity, strength, quality and purity of the final product. Additionally, appropriate packaging  must  be
selected and tested and stability studies must be conducted  to  demonstrate  that  the product drug  does
not undergo unacceptable deterioration  over its shelf life.

U.S. Review and Approval Processes

The results of product development, preclinical studies and clinical trials, along  with descriptions of

the manufacturing process, analytical tests conducted  on the product, proposed labeling and  other
relevant information, are submitted to  the FDA as  part of an NDA for a  new drug or  a BLA for a
biologic, requesting approval to market the  product. The submission of an NDA or BLA  is subject  to
the payment of a substantial user fee; although a waiver  of such  fee may be obtained under certain
limited circumstances. For example, the agency will waive the application fee for  the first human drug
application that a small business or its affiliate submits for  review. The sponsor of  an approved NDA or
BLA is also subject to annual product and establishment user fees.

The FDA reviews all NDAs and BLAs submitted to ensure that they  are  sufficiently complete for

substantive review before it accepts them  for filing.  The FDA may request additional information
rather than accept an NDA or BLA  for filing. In this event, the NDA  or BLA must be re-submitted
with the additional information. The re-submitted application  also is subject to review before the FDA
accepts it for filing. Once the submission  is accepted for filing,  the FDA  begins an in-depth substantive
review. The FDA reviews an NDA to determine, among other things, whether a product is  safe and
effective for its intended use, and a BLA to determine  whether the biologic is  safe, pure,  and potent
for its intended use. The FDA also evaluates  whether  the product’s manufacturing  is cGMP-compliant
to assure the product’s identity, strength, quality  and purity. Before approving  an NDA or BLA,  the
FDA typically will inspect the facility or facilities where the product is or  will be manufactured. The
FDA will not approve an application unless it determines that  the manufacturing processes  and
facilities are in compliance with cGMP requirements  and adequate  to  assure  consistent production of
the product within required specifications. The FDA  may  refer the NDA or  BLA to an advisory
committee for review, evaluation and recommendation as  to  whether the application should be
approved and under what conditions. An advisory  committee is a panel of experts, including clinicians
and  other scientific experts, who provide advice and recommendations when requested  by  the FDA.
The FDA is not bound by the recommendation of an advisory committee, but it  considers  such
recommendations when making decisions.

The approval process is lengthy and difficult and the  FDA may  refuse  to  approve an NDA or BLA

if the applicable regulatory criteria are  not  satisfied  or may require additional clinical data or other
data and information. Even if such data and information  are  submitted, the FDA  may ultimately  decide
that the NDA or BLA does not satisfy the criteria  for approval.  Data obtained from clinical trials are
not always conclusive, and the FDA may interpret data differently than we  interpret  the same data. The

51

FDA will issue a complete response  letter  if  the agency decides not to approve the  NDA or BLA in its
present  form. The complete response  letter usually  describes all  of the specific deficiencies  that  the
FDA identified in the NDA or BLA  that must  be  satisfactorily addressed  before it can be approved.
The deficiencies identified may be minor, for  example, requiring labeling  changes, or major,  for
example, requiring additional clinical trials. Additionally, the  complete response letter may  include
recommended actions that the applicant  might take to place the application in a  condition for  approval.
If a  complete response letter is issued,  the applicant may either resubmit  the NDA or BLA,  addressing
all of the deficiencies identified in the letter,  or withdraw the  application  or request an opportunity  for
a hearing.

If a  product receives regulatory approval, the approval may be significantly  limited to specific
diseases  and dosages or the indications for  use may otherwise  be  limited, which could restrict  the
commercial value of the product. Further,  the FDA may require that certain contraindications,
warnings or precautions be included  in the  product labeling. In addition,  the FDA may require
post-approval studies, including Phase  4 clinical trials, to further assess a product’s safety  and
effectiveness after NDA or BLA approval and may require  testing and  surveillance programs to
monitor the safety of approved products that have  been commercialized. The FDA could also approve
the NDA or BLA with a Risk Evaluation  and Mitigation Strategy  plan to mitigate risks, which  could
include medication guides, physician communication plans, or elements to  assure safe use, such as
restricted distribution methods, patient registries and other risk minimization  tools.

Regulation of Combination Products in the United States

Certain products may be comprised of components  that would normally be regulated under

different types of regulatory authorities, and  frequently by  different  centers at the FDA.  These products
are known as combination products. Specifically, under regulations issued by the FDA,  a combination
product  may be:

(cid:129) a product comprised of two or more regulated components that  are  physically, chemically, or

otherwise combined or mixed and produced as a  single entity;

(cid:129) two or more separate products packaged together in  a single package or as  a unit and comprised
of drug and device products, device and biological  products, or biological  and drug  products;

(cid:129) a drug, device, or biological product packaged separately that according to its investigational

plan  or proposed labeling is intended for  use only with an approved individually specified drug,
device, or biological product where both are required  to  achieve  the intended use,  indication, or
effect and where upon approval of the proposed product the labeling of  the  approved product
would need to be changed, e.g., to reflect  a change in  intended use,  dosage form,  strength, route
of administration, or significant change in  dose; or

(cid:129) any investigational drug, device, or biological product  packaged separately that according to its
proposed labeling is for use only with another  individually specified  investigational  drug,  device,
or biological product where both are required  to  achieve the intended use, indication, or effect.

Under the FDCA, the FDA is charged with assigning a center with primary jurisdiction, or a  lead

center, for review of a combination product. That determination is  based on the  ‘‘primary  mode of
action’’ of the combination product. Thus, if  the primary mode of action of a  device-drug combination
product  is attributable to the drug product, the FDA center responsible for premarket review  of the
drug product would have primary jurisdiction for the combination  product. The FDA  has also
established an Office of Combination Products  to  address issues  surrounding  combination  products and
provide more certainty to the regulatory  review  process. That  office serves as a focal  point for
combination product issues for agency  reviewers and industry. It  is also responsible  for developing
guidance and regulations to clarify the regulation of combination products,  and for assignment of the

52

FDA center that has primary jurisdiction  for  review of combination products where the jurisdiction is
unclear or in dispute.

Expedited Programs

Fast Track Designation

The FDA has a Fast Track program that is  intended to expedite  or  facilitate the process for
reviewing new drugs, including biologics that meet certain criteria.  Specifically,  new drugs are eligible
for Fast Track designation if they are  intended  to  treat a serious or life-threatening disease or  condition
for which there is no effective treatment  and  demonstrate the potential to address  unmet medical
needs for the condition. Fast Track designation applies  to  the combination of the product and the
specific  indication for which it is being  studied. The sponsor of  a  new  drug may  request the FDA to
designate the drug as a Fast Track product concurrently with,  or  at  any  time after, submission  of an
IND, and the FDA must determine if  the  drug candidate qualifies for  fast  track designation within
60 days of receipt of the sponsor’s request.

In addition to other benefits, such as the ability  to  engage in more  frequent interactions with the

FDA, the FDA may initiate review of  sections of a  Fast Track drug’s  NDA or  BLA before the
application is complete. This rolling review is available if the applicant provides,  and the  FDA
approves, a schedule for the submission  of each  portion of the NDA or  BLA and  the applicant  pays
applicable user fees. However, the FDA’s time period  goal for reviewing an  application  does not begin
until the last section of the NDA or BLA is submitted. Additionally, the  Fast Track designation may  be
withdrawn by the FDA if the FDA believes that the  designation  is no  longer supported  by  data
emerging in the clinical trial process.

Accelerated Approval

Under FDA’s accelerated approval regulations, the FDA  may approve a drug, including a biologic,

for a serious or life-threatening illness that provides meaningful therapeutic benefit to patients over
existing treatments based upon a surrogate  endpoint that is  reasonably likely  to  predict clinical  benefit,
or on a clinical endpoint that can be measured earlier than irreversible  morbidity  or mortality,  that  is
reasonably likely to predict an effect  on irreversible  morbidity or mortality or other clinical benefit,
taking into account the severity, rarity,  or  prevalence of the condition and the  availability or lack of
alternative treatments. In clinical trials, a surrogate endpoint  is a marker,  such as a  measurement of
laboratory or clinical signs of a disease  or  condition that is  thought  to  predict clinical  benefit, but  is not
itself a measure of clinical benefit. Surrogate endpoints can often be measured more easily  or more
rapidly than clinical endpoints. A drug candidate approved on this basis  is subject to rigorous
post-marketing compliance requirements,  including  the completion  of  post-approval clinical trials
sometimes referred to as Phase 4 trials to confirm the effect  on the  clinical endpoint. Failure  to
conduct required post-approval studies,  or to confirm a clinical benefit during  post-marketing  studies,
will allow the FDA to withdraw the drug  from the market on an expedited basis.  All promotional
materials for drug candidates approved  under accelerated regulations are subject to prior review by the
FDA.

Breakthrough Designation

The Food and Drug Administration Safety and Innovation Act, or FDASIA, amended the FDCA

to require the FDA to expedite the development and review of a breakthrough therapy. A drug  or
biologic product can be designated as a breakthrough therapy  if it is  intended to treat  a serious or
life-threatening disease or condition  and  preliminary clinical evidence indicates that it  may demonstrate
substantial improvement over existing therapies on one  or more clinically significant endpoints.  A
sponsor  may request that a product be  designated  as a breakthrough  therapy concurrently with, or  at

53

any time after, the submission of an IND, and the FDA must determine if  the candidate qualifies for
breakthrough therapy designation within  60  days of receipt of the  sponsor’s request. If so designated,
the FDA shall act to expedite the development and review  of  the product’s marketing application,
including by meeting with the sponsor  throughout the  product’s development, providing timely advice
to the sponsor to ensure that the development  program  to gather  preclinical and  clinical data is as
efficient as practicable, involving senior managers  and  experienced review staff in  a cross-disciplinary
review, assigning a cross-disciplinary  project lead  for the FDA review  team to facilitate an  efficient
review of the development program and to serve as a  scientific  liaison between the review  team and the
sponsor,  and taking steps to ensure that the design  of  the clinical  trials is  as efficient as  practicable.

Priority Review

Based on results of the Phase 3 clinical  trial(s) submitted  in an NDA or BLA,  upon the  request of

an applicant,  the FDA may grant the NDA for a new molecular entity  or BLA a  priority review
designation, which sets the target date  for FDA action on the application at  six months after the FDA
accepts the application for filing. Priority review  is granted  where there is evidence that the  proposed
product  would be a significant improvement in  the safety or  effectiveness of the  treatment, diagnosis,
or prevention of a serious condition.  If  criteria are not met for priority review, the application is subject
to the standard FDA review period of  ten months after FDA accepts  the application for filing.  Priority
review designation does not change the scientific/medical standard  for  approval or the quality of
evidence necessary to support approval.

Post-Approval Requirements

Any products for which we receive FDA  approval are  subject to continuing regulation by the  FDA,

including, among other things, record-keeping  requirements,  reporting  of  adverse experiences with the
product,  providing the FDA with updated  safety and efficacy information, product  sampling and
distribution requirements, complying  with  certain electronic records  and  signature requirements  and
complying with FDA promotion and  advertising requirements. Moreover, each component of a
combination product retains their regulatory status (as a drug or biologic, for example)  and is subject
to the requirements established by the  FDA for  that  type of component. The FDA strictly regulates
labeling, advertising, promotion and other types  of  information  on products that are placed on the
market. Products may be promoted only for the  approved indications and in accordance with the
provisions of the approved label. Further,  manufacturers  must  continue to comply with cGMP
requirements, which are extensive and  require  considerable  time,  resources  and ongoing investment to
ensure compliance. In addition, changes  to the manufacturing process generally require prior FDA
approval before being implemented and  other types of changes to the approved  product, such as adding
new indications and additional labeling  claims, are  also subject to further FDA review and approval.

Manufacturers and other entities involved in  the manufacturing and distribution of approved
products are required to register their establishments with the FDA and certain state  agencies, and are
subject to periodic unannounced inspections by the FDA and certain state agencies  for compliance with
cGMP and other laws. The cGMP requirements apply to all stages of  the manufacturing  process,
including the production, processing, sterilization,  packaging, labeling, storage and shipment of the
product.  Manufacturers must establish  validated  systems to ensure  that products meet  specifications
and regulatory requirements, and test each  product batch or lot prior to its release. We rely, and expect
to continue to rely, on third parties for  the production of clinical quantities  of  our  drug  candidates.
Future FDA and state inspections may identify compliance issues at the facilities of our contract
manufacturers that may disrupt production or distribution  or  may require substantial resources to
correct.

The FDA may withdraw a product approval or  revoke a biologics license if compliance with
regulatory requirements is not maintained  or if problems  occur after  the product reaches the market.

54

Later discovery of previously unknown  problems with a product may result  in restrictions  on the
product  or even complete withdrawal  of the product  from the market. Further, the  failure to maintain
compliance with regulatory requirements may result in administrative or judicial actions, such  as fines,
untitled or warning letters, holds on clinical trials, product recalls or seizures, product  detention or
refusal to permit the import or export  of products, refusal to approve pending  applications or
supplements, restrictions on marketing or  manufacturing, injunctions  or  civil or criminal  penalties.

From time to time, legislation is drafted,  introduced  and  passed in  Congress that could significantly

change the statutory provisions governing the approval,  manufacturing  and  marketing of  products
regulated by the FDA. In addition to new legislation, FDA  regulations and policies are often revised or
reinterpreted by the agency in ways that  may significantly affect  our business  and our drug candidates.
It  is impossible to predict whether further legislative or FDA regulation or policy changes will be
enacted  or implemented and what the impact of such changes, if  any, may  be.

Patent Term Restoration and Marketing  Exclusivity

Depending upon the timing, duration and specifics of FDA approval of the use of our drug
candidates, some of our U.S. patents  may be eligible for limited patent term extension  under the  Drug
Price Competition and Patent Term Restoration Act of 1984, commonly referred to as the Hatch-
Waxman Amendments. The Hatch-Waxman  Amendments permit  a patent restoration term of up to five
years as compensation for patent term lost during  product development and the FDA  regulatory review
process. However, patent term restoration cannot  extend the remaining term  of a patent beyond a  total
of 14  years from the product’s approval  date. The patent term restoration  period is generally one-half
the time between the effective date of  an  IND and the submission date  of  an NDA or BLA  plus the
time between the submission date of  an  NDA  or BLA and the approval of that application, except that
this  review period is reduced by any time  during  which the  applicant failed to exercise due diligence.
Only one patent applicable to an approved product is eligible  for the  extension and  the application for
the extension must be submitted prior to the expiration of the patent. The  USPTO, in  consultation with
the FDA, reviews and approves the application for any patent term extension  or restoration. In the
future, if available, we intend to apply for  restorations of patent term for some of our currently  owned
patents beyond their current expiration  dates, depending  on the  expected length of the  clinical trials
and other factors involved in the filing of the relevant NDA or  BLA; however,  there can  be  no
assurance that any such extension will  be  granted to us.

Market exclusivity provisions under the FDCA  can also delay the submission or the approval  of

certain applications. The FDCA provides  a five-year period of non-patent marketing exclusivity  within
the United States to the first applicant to gain approval  of an NDA for  a new chemical  entity. A drug
is a new chemical entity if the FDA has not previously approved  any other new drug  containing the
same active moiety, which is the molecule  or ion  responsible for the action of the  drug  substance.
During  the exclusivity period, the FDA may not accept for review an abbreviated new drug application,
or ANDA, or a 505(b)(2) NDA submitted  by another  company for  another version of such drug where
the applicant does not own or have a legal  right of reference to all  the data required for  approval.
However, an application may be submitted after four years  if it contains a certification of  patent
invalidity or non-infringement. The FDCA also  provides three years of  marketing  exclusivity for  an
NDA,  505(b)(2) NDA or supplement to an  existing NDA if new clinical  investigations, other than
bioavailability studies, that were conducted or sponsored by the applicant are deemed  by  the FDA to
be essential to the  approval of the application,  for  example, new indications, dosages or strengths of an
existing drug. This three-year exclusivity  covers only  the conditions of use associated with the new
clinical investigations and does not prohibit the FDA from  approving ANDAs  for drugs  containing the
original active agent. Five-year and three-year exclusivity will  not  delay the submission  or approval of a
full NDA. However, an applicant submitting  a full NDA  would be required  to  conduct  or obtain a right

55

of reference to all of the preclinical studies and  adequate and well-controlled clinical trials necessary to
demonstrate safety and effectiveness.

Pediatric exclusivity is another type of exclusivity in the United States.  Pediatric exclusivity, if
granted, provides an additional six months of  exclusivity, which runs from  the end of other exclusivity
or patent period. Pediatric exclusivity  may  be  granted based  on the voluntary  completion  of  a pediatric
clinical trial in accordance with an FDA-issued ‘‘Written Request’’ for such  a clinical  trial.

Biosimilars and Exclusivity

The Patient Protection and Affordable Care Act, or ACA signed into law on March 23,  2010,
includes a subtitle called the Biologics  Price Competition and Innovation Act  of  2009 which  created  an
abbreviated approval pathway for biological  products shown to be similar to, or  interchangeable  with,
an FDA-licensed reference biological  product. This  amendment  to  the PHSA  attempts  to  minimize
duplicative testing. Biosimilarity, which requires that there  be no clinically  meaningful differences
between the biological product and the  reference product in terms  of safety, purity, and potency, can
be shown through analytical studies, animal  studies, and a clinical trial or  trials. Interchangeability
requires that a product is biosimilar  to  the reference product and the product must demonstrate that it
can be expected to produce the same  clinical results  as the reference product  and, for products
administered multiple times, the biologic  and the reference biologic may be  switched  after one has
been previously administered without  increasing  safety risks  or risks  of diminished  efficacy  relative to
exclusive use  of the reference biologic.

A reference biologic is granted twelve  years  of exclusivity from  the time of  first  licensure  of the
reference product. The first biologic product submitted under the abbreviated approval pathway that is
determined to be interchangeable with  the reference  product has  exclusivity against  other biologics
submitting under the abbreviated approval pathway for the lesser of  (i) one  year after  the first
commercial marketing, (ii) 18 months after approval  if  there is no legal challenge, (iii)  18 months  after
the resolution in the applicant’s favor of  a lawsuit challenging the  biologic’s patents if an application
has been submitted, or (iv) 42 months  after the application has  been approved if  a lawsuit is ongoing
within the 42-month period.

Orphan Drugs

Under the Orphan Drug Act, the FDA may grant orphan  drug  designation  to  drugs, including

biologics, intended to treat a rare disease or condition—generally a disease or condition that affects
fewer than 200,000 individuals in the  United States  or that affects  more than 200,000 individuals  in the
United States and for which there is  no  reasonable  expectation that  costs of  research  and development
of the product for the indication can be recovered by sales of the  product in  the United States.  Orphan
drug designation must be requested before  submitting an NDA or  BLA.

After the FDA grants orphan drug designation, the generic identity of the  drug  or biologic and its
potential orphan use are disclosed publicly by the FDA.  Orphan drug designation does not convey any
advantage in, or shorten the duration  of, the regulatory review  and approval  process. The  first  NDA or
BLA applicant to receive FDA approval  for a particular  active ingredient  to  treat a particular disease
or condition with FDA orphan drug designation  is entitled to a seven-year exclusive marketing period
in the United States for that product, for  that indication. Among  the other benefits  of  orphan drug
designation are tax credits for certain research and  a waiver of the NDA or  BLA application user fee.

During  the exclusivity period, the FDA may not approve any other applications to market the
same drug for the same disease or condition, except  in limited circumstances, such as if the second
applicant demonstrates the clinical superiority of its product  to  the product with orphan drug  exclusivity
through a demonstration of superior  safety, superior efficacy, or a major contribution  to  patient  care.
‘‘Same drug’’ means a drug that contains  the same active  moiety  if it  is a drug composed of small

56

molecules, or the same principal molecular  structural  features if it is composed  of  macromolecules and
is intended for the same use as a previously approved drug, except  that if the subsequent  drug  can be
shown to be clinically superior to the first drug,  it will not be considered to be the same drug.  Orphan
drug exclusivity does not prevent the  FDA from approving a different  drug  for the  same disease or
condition, or  the same drug for a different disease or condition.

Pediatric Information

Under the Pediatric Research Equity Act of 2003, as amended,  NDAs,  BLAs or  supplements  must
contain data adequate to assess the safety and effectiveness of the  product for the claimed indications
in all relevant pediatric subpopulations  and to support dosing and administration for each pediatric
subpopulation for which the product  is  safe and effective. The FDASIA  amended the  FDCA to require
that a sponsor who is planning to submit a marketing application for a product that includes a  new
active  ingredient, new indication, new dosage  form, new  dosing  regimen or new route of administration
submit an initial Pediatric Study Plan,  or  PSP, within 60  days of an end-of-Phase 2  meeting or as may
be agreed between the sponsor and the FDA. The  initial PSP must include  an outline of the pediatric
study or studies that the sponsor plans to conduct, including study objectives and design, age groups,
relevant endpoints and statistical approach, or a  justification for not including such  detailed
information, and any request for a deferral of pediatric assessments or a full  or partial waiver of the
requirement to provide data from pediatric studies  along with  supporting information.  The  FDA  may,
on its own initiative or at the request  of the  applicant, grant deferrals for submission  of  data  or full or
partial waivers. The FDA and the sponsor  must reach agreement  on the  PSP. A sponsor can  submit
amendments to an agreed-upon initial  PSP  at any time  if changes to the pediatric plan need to be
considered based on data collected from preclinical studies,  early  phase  clinical trials,  and/or other
clinical development programs.

Disclosure of Clinical Trial Information

Sponsors of clinical trials of FDA-regulated products, including drugs and biologics, are required to

register and disclose certain clinical trial information, which is  publicly available at
www.clinicaltrials.gov. Information related  to  the product, patient population, phase of  investigation,
study sites and investigators, and other  aspects of the clinical  trial is  then made  public as part  of  the
registration. Sponsors are also obligated to disclose the  results of their  clinical trials after  completion.
Disclosure of the results of these trials  can be delayed until  the new product or new indication being
studied has been approved. Competitors  may use this publicly available information to gain knowledge
regarding the progress of development  programs.

Pharmaceutical Coverage, Pricing and Reimbursement

Significant uncertainty exists as to the coverage and  reimbursement status of any products  for
which  we may obtain regulatory approval. In the United States, sales  of any products  for which we may
receive regulatory approval for commercial sale will depend in part on  the availability of coverage and
reimbursement from third-party payors. Third-party payors include government  authorities,  managed
care providers, private health insurers and other  organizations. The process for determining whether a
payor will provide coverage for a product may be separate from the process for setting the
reimbursement rate that the payor will  pay for the  product. Third-party  payors may limit coverage to
specific  products on an approved list which might not include  all of the FDA-approved products for a
particular indication. Moreover, a payor’s decision to provide coverage  for a product does not imply
that an adequate reimbursement rate  will  be  approved. Adequate third-party  reimbursement may not
be available to enable us to maintain  price levels sufficient  to  realize an  appropriate  return  on our
investment in product development.

57

Third-party payors are increasingly challenging the price  and examining the medical necessity and
cost- effectiveness of medical products  and services,  in addition to their safety and  efficacy.  In  order to
obtain coverage and reimbursement for any product that might be approved for sale,  we may need to
conduct expensive pharmacoeconomic studies  in order to demonstrate the medical necessity and
cost-effectiveness of any products, in  addition to the  costs required to obtain regulatory  approvals. Our
drug candidates may not be considered  medically necessary  or  cost-effective. If third-party  payors do
not consider a product to be cost-effective  compared to other available therapies, they may not cover
the product after approval as a benefit under their plans  or, if they do, the level  of payment may  not
be sufficient to allow a company to sell  its products at  a profit.

The U.S. government and state legislatures  have shown  significant interest in  implementing  cost

containment programs to limit the growth  of government-paid health care costs, including price
controls, restrictions on reimbursement and requirements for substitution  of  generic products for
branded prescription drugs. For example, the ACA, as amended by the Health Care and Education
Reconciliation Act of 2010, collectively, the ACA,  contains provisions  that may reduce  the profitability
of drug products, including, for example, increased rebates  for drugs reimbursed by Medicaid  programs,
extension of Medicaid rebates to Medicaid managed  care plans, mandatory discounts for  certain
Medicare Part D beneficiaries and annual  fees  based on  pharmaceutical companies’ share  of  sales  to
federal health care programs. Adoption of government controls and  measures, and tightening of
restrictive policies  in jurisdictions with existing controls and measures, could limit payments for
pharmaceuticals.

The marketability of any products for  which  we receive regulatory approval for commercial sale

may suffer if the government and third-party  payors  fail to provide  adequate coverage and
reimbursement. In addition, an increasing emphasis  on cost  containment  measures in the  United States
has increased and  we expect will continue to increase the pressure on pharmaceutical  pricing. Coverage
policies and third-party reimbursement  rates may change  at any time.  Even if favorable  coverage  and
reimbursement status is attained for  one  or  more  products  for which we receive regulatory  approval,
less  favorable coverage policies and reimbursement rates may be implemented in  the future.

Other Healthcare Laws and Compliance  Requirements

If we  obtain regulatory approval of our products,  we may  be  subject to various federal and state

laws targeting fraud and abuse in the healthcare industry. These laws may impact, among other things,
our  proposed sales, marketing and education  programs. In addition, we  may be subject to patient
privacy regulation by both the federal  government and the states  in which we  conduct our business.
The laws that may affect our ability to operate include:

(cid:129) the federal Anti-Kickback Statute,  which prohibits, among other things,  persons from knowingly
and willfully soliciting, receiving, offering or paying remuneration, directly or indirectly, in  cash
or in kind, to induce or reward, or in return for, either the  referral of  an individual for, or the
purchase, order, or recommendation  of,  an item  or service reimbursable under  a federal
healthcare program, such as the Medicare and  Medicaid programs;

(cid:129) federal civil and criminal false claims laws and civil monetary  penalty laws, which prohibit,
among other things, individuals or entities  from knowingly presenting, or causing to be
presented, claims for payment from Medicare, Medicaid, or  other  third-party payors  that  are
false or fraudulent, or making a false  statement or  record material to payment of a false claim
or avoiding, decreasing, or concealing an obligation to pay money to the  federal government;

(cid:129) the federal Health Insurance Portability and Accountability Act of  1996, or HIPAA, which

created new federal criminal statutes  that prohibit executing a scheme  to  defraud any  healthcare
benefit program and making false statements relating to healthcare matters;

58

(cid:129) the federal transparency laws, including the federal Physician Payment Sunshine Act, which is
part of the ACA, that requires applicable  manufacturers of covered drugs and  biologics to
disclose payments and other transfers of value  provided to physicians and teaching hospitals and
physician ownership and investment  interests;

(cid:129) HIPAA, as amended by the Health  Information Technology  for Economic and  Clinical  Health

Act and its implementing regulations,  which imposes certain requirements relating to the privacy,
security and transmission of individually identifiable health information; and

(cid:129) state law equivalents of each of the above  federal laws,  such as anti-kickback  and false  claims

laws which may apply to items or services reimbursed  by  any third-party payor, including
commercial insurers, and state laws governing  the privacy  and security of  health information in
certain circumstances, many of which differ from each other in significant ways and  may not
have the same effect, thus complicating compliance efforts.

The ACA broadened the reach of the fraud and abuse laws by, among other things, amending the

intent requirement of the federal Anti-Kickback Statute and the applicable criminal healthcare fraud
statutes contained within 42 U.S.C. §  1320a-7b. Pursuant to the statutory  amendment,  a person or
entity no longer needs to have actual knowledge of  this statute or specific intent  to  violate it in  order
to have committed a violation. In addition, the  ACA provides that the government  may assert that a
claim including items or services resulting  from  a violation of the federal Anti-Kickback  Statute
constitutes a false or fraudulent claim for  purposes of the  civil  False Claims Act or  the civil monetary
penalties statute. Many states have adopted laws similar to the  federal  Anti-Kickback Statute, some of
which  apply to the referral of patients for  healthcare  items or services  reimbursed by any source, not
only the Medicare and Medicaid programs.

The federal False Claims Act prohibits anyone from,  among  other things,  knowingly presenting, or

causing to be presented, for payment to federal programs (including  Medicare and Medicaid) claims
for items or services that are false or  fraudulent. Although  we  would not submit claims directly to
payors, manufacturers can be held liable  under these laws if they are deemed  to  ‘‘cause’’ the  submission
of false or fraudulent claims by, for example, providing inaccurate  billing  or coding information to
customers or promoting a product off-label. In addition, our future  activities  relating to the reporting of
wholesaler or estimated retail prices  for our  products, the  reporting of prices  used to calculate
Medicaid rebate information and other information affecting federal,  state, and third-party
reimbursement for our products, and  the  sale and marketing of  our products, are subject  to  scrutiny
under this law. For example, pharmaceutical companies have been prosecuted  under the  federal False
Claims Act in connection with their off-label promotion of drugs. Penalties for a False  Claims Act
violation include three times the actual  damages sustained by  the government,  plus mandatory civil
penalties of between $10,781 and $21,563  for each  separate false claim, the potential for exclusion from
participation in federal healthcare programs, and, although  the federal False Claims Act is a civil
statute, conduct that results in a False  Claims  Act violation  may also implicate  various federal  criminal
statutes. In addition, private individuals have  the ability to bring actions under the  federal False Claims
Act and certain states have enacted laws modeled  after the federal False Claims Act.

59

Patient Protection and Affordable Care Act

In March 2010, the ACA was enacted,  which includes  measures that  have or  will significantly

change the way health care is financed  by  both governmental  and private insurers. Among  the
provisions of the ACA of greatest importance to the pharmaceutical industry are  the following:

(cid:129) The Medicaid Drug Rebate Program requires pharmaceutical manufacturers  to  enter into and

have in effect a national rebate agreement with the Secretary of the Department of Health and
Human Services as a condition for states to receive federal  matching funds for the
manufacturer’s outpatient drugs furnished  to  Medicaid patients. The ACA  made several  changes
to the  Medicaid Drug Rebate Program, including increasing pharmaceutical manufacturers’
rebate liability by raising the minimum basic  Medicaid rebate on most branded prescription
drugs from 15.1% of average manufacturer price, or AMP, to 23.1% of AMP, and adding a new
rebate calculation for ‘‘line extensions’’ (i.e.,  new formulations, such as  extended release
formulations) of solid oral dosage forms of branded products, as well as potentially impacting
their rebate liability by modifying the statutory definition of AMP. The ACA also  expanded the
universe  of Medicaid utilization subject to drug rebates by  requiring  pharmaceutical
manufacturers to pay rebates on Medicaid managed care utilization and by expanding the
population potentially eligible for Medicaid drug benefits.  In addition, the  ACA provides  for the
public availability of retail survey prices and certain weighted average AMPs under  the Medicaid
program. The implementation of this requirement by Centers for Medicare  & Medicaid Services,
or CMS, may also provide for the public availability  of pharmacy acquisition  of  cost data, which
could negatively impact our sales.

(cid:129) In  order for a pharmaceutical product to receive  federal  reimbursement  under the  Medicare

Part B and Medicaid programs or to  be  sold  directly  to  U.S. government agencies, the
manufacturer must extend discounts  to  entities  eligible to participate in the 340B drug pricing
program. The required 340B discount on a given  product is  calculated based on the  AMP and
Medicaid rebate amounts reported by the  manufacturer. The ACA  expanded the  types of
entities eligible to receive discounted 340B pricing, although, under the  current state of the law,
with the exception of children’s hospitals,  these newly eligible  entities  will not be eligible to
receive discounted 340B pricing on orphan drugs  when used for the orphan indication.  In
addition, as 340B drug pricing is determined based on AMP and Medicaid rebate  data,  the
revisions to the Medicaid rebate formula and AMP definition described above  could  cause the
required 340B discount to increase.

(cid:129) The ACA imposed a requirement on manufacturers of branded drugs to  provide a 50% discount
off the negotiated price of branded drugs  dispensed  to  Medicare Part D patients in  the coverage
gap (i.e., the ‘‘donut hole’’).

(cid:129) The ACA imposed an annual, nondeductible fee on any entity  that manufactures or imports

certain branded prescription drugs, apportioned  among  these  entities according to their market
share in certain government healthcare programs, although  this  fee would  not  apply to sales of
certain products approved exclusively for orphan indications.

(cid:129) The ACA required pharmaceutical  and  biologics manufacturers to track certain  financial

arrangements with physicians and teaching hospitals, including any ‘‘transfer of value’’ made  or
distributed to such entities, as well as  any investment  interests held by  physicians  and their
immediate family members. Manufacturers report  this information to CMS  annually.  The
reported information is publicly available  in a searchable format on a CMS  website.

(cid:129) A new Patient-Centered Outcomes Research Institute  was  established pursuant to the ACA to

oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with

60

funding for such research. The research conducted by the Patient-Centered Outcomes Research
Institute may affect the market for certain pharmaceutical products.

(cid:129) The ACA created the Independent Payment Advisory  Board which, if impaneled, has authority
to recommend certain changes to the Medicare  program to reduce expenditures  by  the program
that could result in reduced payments for prescription drugs.  Under certain  circumstances, these
recommendations will become law unless Congress  enacts legislation  that will  achieve the same
or greater Medicare cost savings.

(cid:129) The ACA established the Center for Medicare  and Medicaid  Innovation  within Center for
Madicare and Medicaid Services, or  CMS, to test  innovative payment  and  service  delivery
models to lower Medicare and Medicaid  spending,  potentially including prescription drug
spending. Funding has been allocated to support the  mission of the Center for Medicare  and
Medicaid Innovation from 2011 to 2019.

Since its enactment, there have been judicial and  Congressional  challenges to numerous  aspects of
the ACA. In January, Congress voted  to  adopt  a budget resolution for fiscal year 2017  that,  while not a
law, is widely viewed as the first step  toward the passage of legislation to repeal the  ACA. Further, on
January 20, 2017, President Trump signed  an  Executive Order directing  federal agencies with
authorities and responsibilities under the ACA  to  waive, defer, grant exemptions  from, or delay  the
implementation of any provision of the  ACA that would  impose a fiscal or  regulatory burden on  states,
individuals, healthcare providers, health  insurers,  or manufacturers of pharmaceuticals or medical
devices. Congress also could consider  subsequent legislation  to  replace  elements of the ACA that are
repealed. We cannot predict how the  ACA, its possible  repeal, any  legislation that may be proposed to
replace the ACA, or the political uncertainty surrounding any repeal or replacement  legislation will
affect our business.

PRC Regulation

In the PRC, we operate in an increasingly complex legal and regulatory environment. We are
subject to a variety of PRC laws, rules  and  regulations affecting many aspects of our business. This
section summarizes the principal PRC  laws, rules  and  regulations relevant to our business and
operations.

General Regulations on China Food and Drug  Administration

In the PRC, the CFDA monitors and  supervises the administration of  pharmaceutical products, as

well as medical devices and equipment.  The CFDA’s  primary  responsibility includes evaluating,
registering and approving new drugs,  generic drugs, imported drugs and traditional Chinese medicines;
approving and issuing permits for the manufacture, export and  import of  pharmaceutical products  and
medical appliances; approving the establishment  of  enterprises for  pharmaceutical  manufacture and
distribution; formulating administrative  rules and policies concerning  the supervision  and administration
of food, cosmetics and pharmaceuticals;  and  handling significant accidents  involving these products.  The
local provincial drug administrative authorities are responsible for supervision and  administration of
drugs within their respective administrative  regions.

The PRC Drug Administration Law promulgated by the Standing Committee  of the National
People’s Congress in 1984 and the Implementing Measures of the PRC Drug Administration Law
promulgated by the Ministry of Health, or  the MOH, in 1989  set forth the  legal framework  for the
administration of pharmaceutical products, including the research, development  and manufacturing of
drugs.

The PRC Drug Administration Law was revised in December 2001, April 2015, and  most recently

in January 2017. The purpose of the revisions in 2015 was  to  strengthen the  supervision and
administration of pharmaceutical products and to ensure the quality and safety  of those products for

61

human use. The revised PRC Drug Administration Law applies to entities and individuals engaged in
the development, production, trade, application, supervision and  administration  of pharmaceutical
products. It regulates and prescribes a  framework for the administration of pharmaceutical preparations
of medical institutions and for the development,  research, manufacturing, distribution, packaging,
pricing and advertising of pharmaceutical products. The amendment of  PRC  Drug  Administration Law
in January 2017 removed the preview  procedure  at the  provincial level for  qualification approval of
drug clinical trial institutions. Revised  Implementing Measures of the PRC Drug Administration  Law
promulgated by the State Council took  effect in September 2002 and was most recently amended  in
February 2016, providing detailed implementing regulations  for the revised PRC  Drug  Administration
Law. The Revised Implementing Measures removed  the obtainment  of Drug  Manufacturing License  or
a Drug Distribution License as a precondition for incorporation of a drug  manufacturer or  a drug
distributor, in order to simplify the business administration process for drug companies.

Under these regulations, we need to  follow  related regulations for  preclinical research, clinical

trials and production of new drugs.

Good Laboratories Practice Certification for Preclinical Research

To improve the quality of preclinical  research, the CFDA  promulgated  the Administrative

Measures for Good Laboratories Practice  of Preclinical Laboratory  in 2003 and began to conduct  the
certification program of GLP. In April  2007, the CFDA issued the Circular on Measures  for
Certification of Good Laboratory Practice, or CFDA  Circular  214, providing  that  the CFDA is
responsible for certification of preclinical research institutions. Under  CFDA Circular  214, the CFDA
decides  whether an institution is qualified  for undertaking pharmaceutical  preclinical research upon the
evaluation of the institution’s organizational  administration, its research personnel, its equipment and
facilities and its operation and management of preclinical pharmaceutical projects. If all requirements
are met, a GLP Certification will be issued by the CFDA and the result will be published on  the
CFDA’s  website.

Currently for all our ongoing projects,  we cooperated with CFDA certified GLP laboratories
operated  by Wuxi  AppTec (Suzhou) Co., Ltd.  and JOINN Laboratories  (Beijing) to conduct  the studies
following GLP based on CFDA requirements.

Approval for Clinical Trials and Production of New Drugs

According to the Provisions for Drug Registration  promulgated by  the CFDA in 2007,  Drug
Administration Law promulgated and  amended  by the Standing  Committee of the  National People’s
Congress in 2015, Circular on Regulations for Special Approval  on  New  Drug Registration issued  by
the CFDA in 2009, and Circular on Information  Publish Platform  for  Pharmaceutical  Clinical Trials
issued by the CFDA in 2013, we must comply with  the following procedures and  obtain  several
approvals for clinical trials and production  of new drugs.

Clinical Trial Application

Upon completion of its preclinical research, a  sponsor  must  apply for approval of a  Clinical  Trial

Application before conducting clinical  trials.

Special Examination and Approval for Domestic Category 1 Pharmaceutical  Products

Domestic Category 1 New Drugs Are  Eligible for Special Examination and Approval

According to Provisions for Drug Registration promulgated by the CFDA  in 2007, drug registration

applications are divided into three different  types,  namely  Domestic NDA,  Domestic Generic  Drug
Application, and Imported Drug Application. Drugs fall  into  one  of  three categories, namely chemical
medicine, biological product, or traditional  Chinese  or natural medicine. A Category 1 drug is a new

62

drug that has never been marketed in  any  country.  All of our clinical-stage drug  candidates qualify as
domestic Category 1 new drugs.

According to Provisions on the Administration  of Special Examination and Approval of

Registration of New Drugs, or the Special  Examination and Approval  Provisions promulgated by the
CFDA in January 2009, the CFDA conducts special examination and  approval for new  drugs
registration application when:

(1) the chemical raw material medicines as well as the  preparations  and  biological products

thereof haven’t been approved for marketing  home and abroad;

(2) the new drugs are for treating AIDS, malignant tumors and rare diseases, etc.,  and have

obvious advantages in clinic treatment;  or

(3) the new drugs are for treating diseases with no  effective  methods of treatment.

The Special Examination and Approval  Provisions provide that  the  applicant may  file for  special
examination and approval at the stage  of  Clinical Trial Application if the drug  candidate falls  within
item (1). The provisions provide that  for drug  candidates that fall within items (2)  or (3),  the
application for special examination and approval must be made when  filing  for production.

We  believe that BGB-3111, BGB-A317, BGB 290 and BGB-283 fall  within items (1)  and

(2) above. Therefore, we may file an application for special  examination and approval  at the Clinical
Trial Application stage, which may enable us to pursue  a more expedited path to approval  in China  and
bring therapies to patients more quickly.

The Advantages of Category 1 New Drugs over Imported Drugs

Imported drugs are drugs manufactured outside China. Drugs which  have already been  marketed

abroad by multinational companies, but are not yet  approved in  China  are required  to  follow the
process applicable to imported drugs in registration.  Compared with  the application for  imported drugs,
the application for Category 1 domestic new drugs has a  more straight-forward registration pathway.
According to Provisions for Drug Registration, where a  special examination and approval treatment is
granted, the application for clinical trial and manufacturing will  be  handled  with priority and with
enhanced communication with the Center  for Drug Evaluation of  the  CFDA, or the CDE,  which will
establish a working mechanism for communicating  with the applicants. If  it becomes necessary to revise
the clinical trial scheme or make other  major alterations  during the clinical trial, the applicant may file
an application for communication. According to the Administrative Measures on Communications for
Drug Development and Technical Evaluation issued by CFDA in June 2016, when an application for
communication is approved, the CDE  will  arrange the communication  with the applicant within  30 to
60 days, depending on the subject matter of such communication.

In comparison, according to Provisions  for Drug Registration, the  registration pathway for

imported drugs is complicated and evolving. Imported drug applications may only be submitted after a
company obtains an NDA approval and  receive the  CPP granted by a major regulatory  authority,  such
as the FDA or the EMA. Multinational companies may need to apply for conducting MRCTs, which
means that companies do not have the flexibility  to  design the clinical trials to fit  the Chinese patients
and standard-of-care. Imported drug candidates under  Category 5 cannot qualify for the national
priority list to benefit from fast track  reviews.  Moreover,  a  requirement  to  further conduct local  clinical
trials can potentially delay market access  by several  years  from its international NDA approval.

Our drug candidates are all new therapeutic agents  and the  registration applications for  all  four of

them are filed under Category 1. The CFDA has approved our Clinical Trial Applications for all four
of our drug candidates, i.e. BGB-3111, BGB-A317, BGB-283, and BGB-290, including  all  phases of
their clinical trials.

Changes to the Review and Approval  Process

In August 2015, the Chinese State Council issued a statement, Opinions on reforming the review and

approval  process for pharmaceutical products  and medical devices, that contained several potential policy
changes that could benefit the pharmaceutical  industry:

(cid:129) A plan to accelerate innovative drug  approval with a special  review and approval process, with  a
focus on areas of high unmet medical needs, including  drugs  for HIV, cancer, serious infectious
diseases,  orphan diseases and drugs on national  priority lists.

(cid:129) A plan to adopt a policy which would  allow companies to act as  the marketing authorization

holder and to hire contract manufacturing organizations  to produce drug products.

(cid:129) A plan to improve the review and  approval of clinical trials, and to allow companies  to  conduct
clinical trials at the same time as they are in other countries and encourage local clinical trial
organizations to participate in international multi-center clinical trials.

In November 2015, the CFDA released  the Circular Concerning Several Policies on Drug Registration

Review and Approval, which further clarified the following policies potentially  simplifying and
accelerating the approval process of clinical trials:

(cid:129) A one-time umbrella approval procedure allowing approval  of all phases of a  new drug’s  clinical
trials at once, rather than the current phase-by-phase  approval procedure, will be adopted for
new drugs’ clinical trial applications.

(cid:129) A fast track drug registration or clinical trial approval pathway will be available for the following

applications: (1) registration of innovative new drugs treating HIV, cancer, serious infectious
diseases and orphan diseases; (2) registration of pediatric drugs; (3) registration of  geriatric
drugs and drugs treating China-prevalent diseases; (4) registration of drugs sponsored by
national science and technology grants; (5) registration of  innovative drugs using advanced
technology, using innovative treatment methods, or having distinctive clinical benefits;
(6) registration of foreign innovative drugs to be manufactured locally in China; (7) concurrent
applications for new drug clinical trials which are already approved  in the United  States or
European Union, or concurrent drug registration applications for drugs which  have applied for
marketing authorization and passed onsite inspections in  the United States or European Union
and  are manufactured using the same production  line in China;  and  (8) clinical trial applications
for drugs with urgent clinical need and patent expiry within three  years,  and  marketing
authorization applications for drugs with urgent clinical need and patent expiry  within one year.

In February 2016, the CFDA released  the Opinions on Priority Review and Approval  for Resolving

Drug Registration Applications Backlog, which further clarified the following policies  potentially
accelerating the approval process of certain  clinical trials  or drug registrations which may benefit  us:

(cid:129) A fast  track drug registration or clinical trial approval pathway will be available for the following
drug registration applications with distinctive  clinical benefits: (1)  registration  of  innovative drugs
not sold within or outside China; (2) registration  of innovative drug transferred to be
manufactured in China; (3) registration of drugs using  advanced technology,  using innovative
treatment methods, or having distinctive treatment advantages;  (4) clinical trial applications for
drugs patent expiry within three years, and marketing authorization applications for  drugs with
patent expiry within one year; (5) concurrent applications  for  new drug clinical trials which  are
already approved in the United States  or European Union, or concurrent drug registration
applications for drugs which have applied  for marketing  authorization and passed onsite
inspections in the United States or European Union and are manufactured  using  the same
production line in China; (6) traditional Chinese medicines (including ethnic medicines) with
clear position in prevention and treatment of serious  diseases; and (7) registration  of new drugs
sponsored by national key technology projects or national key development projects.

64

(cid:129) A fast  track drug registration approval pathway will be available for the following drugs

registration application with distinctive clinical  benefits for prevention  and  treatment of HIV,
phthisis, virus hepatitis, orphan diseases, cancer, children’s  diseases,  and geriatrics.

In March 2016, the CFDA released a  circular, CFDA Announcement on Reforms of Pharmaceutical

Registration Classification, which outlined the re-classifications of drug applications. Under the new
categorization, innovative drugs that  have not been approved  either in  or outside  China remain
Category 1, while drugs approved outside  China seeking marketing approval in China  are now
Category 5.

The CFDA may release detailed policies regarding  such  abovementioned fast track  clinical trial
approval and drug registration pathway, and we expect that the CFDA review  and approval  process  will
improve over time. However, how and when this approval process  will be changed is still  subject to
further policies to be issued by the CFDA and is currently uncertain.

Subsidies and Preferential Tax Treatment for ‘‘12-5  Major  New Drugs Development Projects’’

In 2012, the Chinese State Council adopted a ‘‘12-5 Major New Drugs Development  Projects,’’
according to which a special fund was established  by the  government to encourage the development  of
new drugs. Our BGB-283 drug candidate and another  BRAF preclinical research project  have been
recognized as ‘‘12-5 Major New Drugs Development Projects’’  and received government  subsidies of
RMB 6,554,600 during the period from January 1, 2013  to December 31, 2015.

PRC Enterprise Income Tax Law and  Its  Implementation

The PRC Enterprise Income Tax Law, or EIT Law, and its implementation rules permit certain

High and New Technologies Enterprises, or HNTEs, to enjoy preferential enterprise  income  tax rates
subject  to these HNTEs meeting certain  qualification criteria.  In April 2008,  the State Administration
of Taxation, or SAT, the Ministry of Science and Technology, or  MOST and  the Ministry of Finance, or
MOF jointly issued the  Administrative Rules for the Certification of  High and New Technology Enterprises
specifying the criteria and procedures for the certification of HNTEs.  In  January 2016, revised version
of the Administrative Rules for the Certification  of High and New Technology Enterprises has been issued
by the SAT, the MOST and the MOF, and replaced the  2008 version,  while the material criteria of
HNTEs remains unchanged.

Pursuant to the Temporary Regulations on Business Tax,  which were promulgated by the Chinese

State Council on December 13, 1993 and effective as of  January  1, 1994,  as amended  on November 10,
2008 and effective as of January 1, 2009, any entity  or individual conducting business in  a service
industry is generally required to pay business tax at  the rate of 5% on the revenues generated from
providing such services. However, if the services provided are related to technological development and
transfer, such business tax may be exempted subject to approval by  the relevant  tax authorities.

In November 2011, the MOF and the SAT promulgated the  Pilot Plan for Imposition of Value-
Added Tax, or VAT, to Replace Business Tax, or the  Pilot Plan. Since January 2012,  the SAT has  been
implementing the Pilot Plan, which imposes VAT,  in lieu  of business  tax  for certain industries  in
Shanghai. The Pilot Plan was expanded to other regions, including  Beijing, in September 2012,  and was
further expanded nationwide beginning August 1, 2013. VAT is  applicable  at a  rate of 6% in lieu  of
business taxes for certain services and 17% for the sale of  goods and provision of tangible property
lease services. VAT payable on goods  sold  or taxable services provided  by a general VAT taxpayer for a
taxable period is the net balance of the  output VAT for the period after crediting the input VAT for
the period.

65

Four Phases of Clinical Trials

A clinical development program consists of Phases  1, 2, 3 and  4. Phase 1 refers to the initial
clinical pharmacology and safety evaluation studies in  humans. Phase 2 refers to the  preliminary
evaluation of a drug candidate’s therapeutic effectiveness and safety  for particular indication(s) in
patients, provide evidence and support for the design of Phase  3 clinical  trial, and settle the
administrative dose regimen. Phase 3  refers to clinical  trials undertaken to confirm the therapeutic
effectiveness of a drug. Phase 3 is used  to  further verify  the drug’s therapeutic  effectiveness and safety
on patients with target indication(s),  to  evaluate overall benefit-risk relationships  of the drug, and
ultimately to provide sufficient evidence for the  review of drug registration  application.  Phase 4  refers
to a new drug’s post-marketing study  to  assess therapeutic  effectiveness and adverse reactions  when the
drug is widely used, to evaluate overall benefit-risk relationships  of  the drug when used among general
population or specific groups, and to  adjust the  administration  dose, etc.

New Drug Application

When Phases 1, 2 and 3 of the clinical trials have  been completed, the applicant  must  apply to the

CFDA for approval of a NDA. The CFDA then determines whether to approve  the application
according to the comprehensive evaluation  opinion provided by  the CDE of the CFDA. We  have
obtained approval of our Clinical Trial  Applications  for BGB-283, BGB-3111, BGB-290 and BGB-A317
in the PRC, and clinical trials have been  initiated.  We must obtain approval  of  a NDA before our drugs
can be manufactured and sold in the  PRC market.

Good Manufacturing Practice

All facilities and techniques used in the manufacture of products for clinical use  or for  sale in the

PRC must be operated in conformity with  cGMP guidelines as established by the  CFDA. Failure to
comply  with applicable requirements could result in the termination of manufacturing and  significant
fines.

Animal Test Permits

According to Regulations for the Administration of Affairs  Concerning Experimental  Animals
promulgated by the State Science and Technology Commission in November 1988  and Administrative
Measures on the Certificate for Animal Experimentation promulgated by the State Science and
Technology Commission and other regulatory  authorities in January 2001, performing experimentation
on animals requires a Certificate for  Use of  Laboratory Animals. Applicants must satisfy  the following
conditions:

(cid:129) Laboratory animals must be qualified and  sourced from  institutions that have Certificates for

Production of Laboratory Animals;

(cid:129) The environment and facilities for  the  animals’ living and  propagating must meet  state

requirements;

(cid:129) The animals’ feed and water must meet state requirements;

(cid:129) The animals’ feeding and experimentation must be conducted  by professionals, specialized and

skilled workers, or other trained personnel;

(cid:129) The management systems must be effective and  efficient; and

(cid:129) The applicable entity must follow other requirements as stipulated by the PRC laws and

regulations.

We  obtained a Certificate for Use of Laboratory Animals in 2012 regarding the  scope of rats and

mice.

Regulations Relating to Intellectual Property  Rights

Patent

General

Pursuant to the Patent Law of the PRC and its implementation  rules,  patents in the PRC fall into
three categories, namely invention patent, utility model and design patent. Invention  patent  refers to a
new technical solution proposed in respect of a  product, method or its  improvement; utility model
refers to a new technical solution that is  practicable for application and proposed  in respect of the
shape, structure or a combination of both of a product; and design  patent  refers to the new  design of a
certain product in shape, pattern or a  combination  of both and  in color, shape and pattern
combinations aesthetically suitable for  industrial  application.  Under the  Patent Law of the  PRC, the
term of patent protection starts from  the date the patent was filed. Patents  relating to utility-models
and designs are effective for ten years from the initial date the patent application was filed. The Patent
Law of the PRC adopts the principle of  ‘‘first to file,’’ which means where more than one person files a
patent application for the same invention, a patent  will be granted to the person  who first filed the
application.

Existing patents can become invalid or unenforceable due to a number of factors,  including known
or unknown prior art, deficiencies in patent application and lack  of novelty in technology. In the PRC,
a patent must have novelty, innovation and practical application.  Under  the Patent Law of PRC,
novelty means that before a patent application is filed, no  identical invention or utility model has  been
publicly disclosed in any publication  in  the PRC  or abroad or has been publicly used or made known to
the public by any other means, whether  in  or outside of China, nor has any other person  filed with the
patent authority an application that describes an  identical invention or utility model and is  published
after the filing date. Patents in the PRC are filed  with the State Intellectual  Property Office,  or SIPO.
Normally, the SIPO publishes an application for a  pharmaceutical  invention  18 months  after the
application is filed, which may be shortened upon  request  by  the applicant.  The applicant  must  apply to
the SIPO for a substantive examination  within three years from  the date the  application  is filed.

Article 20 of the Patent Law of the PRC  provides that, for an invention or  utility model completed

in China, any applicant, not just Chinese companies and individuals,  before filing a patent application
outside of China, must first submit it  to  the  SIPO  for  a confidential examination.  Failure to comply
with this  requirement will result in the denial of any Chinese patent for the subject  invention.  This
added requirement of confidential examination by the  SIPO has raised concerns by foreign companies
who conduct research and development  activities in the PRC  or outsource research and development
activities to service providers in the PRC. Currently we  have three invention  patents published by SIPO
and one invention patent under the application  process.

Patent Enforcement

Unauthorized use of patents without  consent from owners of patents,  forgery of the patents
belonging to other persons, or engagement in other infringement  acts  against patent rights, will subject
the infringers to tortious liabilities. Serious offences may be subject  to  criminal penalties.

When a dispute arises as a result of  infringement  of  the patent owner’s patent right, PRC  law

requires that the parties first attempt to settle  the dispute  through consultation  between  them.
However, if the dispute cannot be settled  through consultation, the  patent  owner, or an  interested  party
who believes the patent is being infringed, may either file a civil legal suit or  file an administrative
complaint with the relevant patent administration authority under the SIPO. A PRC court may issue  a
preliminary injunction upon the patent  owner’s or an interested party’s  request  before  instituting any
legal proceedings or during the proceedings. Damages  for  infringement are calculated as either the loss
suffered by the patent holder arising from  the infringement  or  the benefit  gained by the infringer from
the infringement. If it is difficult to ascertain  damages in this manner, damages may  be  determined by

67

using a reasonable multiple of the license fee under a  contractual license. As in other jurisdictions, with
one notable exception, the patent owner in  the PRC has  the burden  of proving that the patent is  being
infringed. However, if the owner of a manufacturing  process patent alleges  infringement of its patent,
the alleged infringer has the burden of proving that it has not infringed. To  our knowledge, there are
no disputes as to our infringement of any third party’s patent.

Medical Patent Compulsory License

According to the Patent Law of the PRC, the SIPO may  grant a compulsory license for
manufacturing patented drugs and exporting them to countries or regions covered under  relevant
international treaties to which the People’s Republic of  China  has acceded.

Exemptions for Unlicensed Manufacture,  Use and Import of Patented Drugs

According to the Patent Law of the PRC, any person may manufacture, use or import patented
drugs for the purpose of providing information required for administrative  examination  and approval
without authorization granted by the patent owner.

Trade Secrets

According to the Anti-Unfair Competition Law of the PRC, the  term ‘‘trade secrets’’ refers  to
technical information and business information that is unknown to the  public, that has  utility and  may
create business interest or profit for  its legal owners or  holders, and that  is maintained as a  secret  by
its  legal owners or holders.

Under this law, business persons are  prohibited from  employing the following methods to infringe

trade secrets: (1) obtaining the trade  secrets from the legal owners or holders by any unfair methods
such as stealing, solicitation or coercion;  (2) disclosing, using  or  permitting others to use the trade
secrets obtained illegally under item  (1) above;  or (3)  disclosing, using or permitting  others to use  the
trade secrets, in violation of any contractual agreements or any requirements of  the legal owners or
holders  to keep such trade secrets in  confidence. If a  third  party knows or should have known of the
above-mentioned illegal conduct but nevertheless obtains,  uses or discloses trade  secrets  of others, the
third party may be deemed to have committed a  misappropriation of the others’  trade secrets. The
parties whose trade secrets are being  misappropriated  may  petition for administrative  corrections,  and
regulatory authorities may stop any illegal activities and fine infringing parties in the amount of
RMB 10,000—200,000. Alternatively, persons whose trade  secrets are being misappropriated may file
lawsuits in a PRC court for loss and  damages caused  by the misappropriation.

The measures to protect trade secrets include oral or written agreements  or other reasonable
measures to require the employees of, or persons in business contact with, legal owners or holders to
keep  trade secrets confidential. Once the  legal owners or holders have asked others to keep  trade
secrets confidential and have adopted  reasonable  protection measures,  the  requested persons bear the
responsibility for keeping the trade secrets confidential.

Regulations Relating to Foreign Exchange and Dividend Distribution

Foreign Exchange Regulation

The Foreign Exchange Administration  Regulations, most  recently amended in  August  2008, are the

principal regulations governing foreign currency exchange in  China. Under the  PRC foreign exchange
regulations, payments of current account  items, such as profit distributions and  trade and  service-
related foreign exchange transactions, may be made  in foreign  currencies without  prior approval from
the State Administration of Foreign Exchange, or SAFE, by complying with certain procedural
requirements. In contrast, approval from or  registration with  appropriate government authorities  is

68

required when RMB is to be converted  into a foreign currency  and remitted out of China to pay
capital expenses such as the repayment of  foreign currency-denominated  loans.

In August 2008, SAFE issued the Circular on the Relevant Operating  Issues Concerning the

Improvement of the Administration of  the Payment and Settlement of Foreign Currency Capital  of
Foreign-Invested Enterprises, or SAFE  Circular  142, regulating  the conversion by a foreign-invested
enterprise of foreign currency-registered capital into RMB by  restricting how the  converted  RMB may
be used. In addition, SAFE promulgated Notice on Issues concerning Further Clarifying  and Regulating
the Foreign Exchange Administration under  Some  Capital Accounts, or Circular 45,  on November  9,
2011 to clarify the application of SAFE Circular  142. Under SAFE Circular 142 and Circular 45, RMB
capital converted from foreign currency registered capital of a foreign-invested enterprise  may only be
used for purposes within the business scope approved by the  applicable  government authority and may
not be used for equity investments within the PRC. In addition, SAFE strengthened its oversight of the
flow and use of the RMB capital converted from foreign  currency registered capital of foreign-invested
enterprises. The use of such RMB capital  may not be changed  without  SAFE’s  approval, and  such
RMB capital may not, in any case, be  used to repay RMB loans  whose  proceeds were not used.
Furthermore, SAFE promulgated Notice on Issues Concerning Strengthening Administration of Foreign
Exchange Services in November 2010, which tightens the regulation over settlement of net proceeds
from overseas offerings, such as our  initial public offering, and requires,  among other  things, the
authenticity of settlement of net proceeds from offshore  offerings to be closely examined and  the net
proceeds to be settled in the manner  described in our prospectus  or  otherwise approved by our board
of directors. Violations of these SAFE  regulations may result in severe monetary or  other penalties,
including confiscation of earnings derived from  such violation activities,  a  fine of up  to  30% of the
RMB funds converted from the foreign invested funds or  in the case of a severe violation,  a fine
ranging from 30% to 100% of the RMB funds  converted  from the foreign-invested funds.

In November 2012, SAFE promulgated the  Circular  of Further Improving and Adjusting Foreign

Exchange Administration Policies on Foreign Direct Investment,  which substantially amends and
simplifies the current foreign exchange procedure. Pursuant to this circular, the opening of various
special purpose foreign exchange accounts, such  as pre-establishment expenses accounts, foreign
exchange capital accounts and guarantee  accounts, the reinvestment of RMB proceeds by foreign
investors in the PRC, and remittance of  foreign exchange profits and  dividends by a foreign-invested
enterprise to its foreign shareholders no  longer  require the approval or verification  of  SAFE, and
multiple capital accounts for the same entity may  be  opened in  different  provinces, which was not
previously possible. In addition, SAFE promulgated  the Circular  on  Printing and Distributing the
Provisions on Foreign Exchange Administration over  Domestic  Direct Investment by Foreign Investors
and the Supporting Documents in May  2013, which specifies that  the administration by the SAFE  or its
local branches over direct investment  by  foreign investors in the  PRC will be conducted by way of
registration, and banks must process  foreign exchange business  relating to the  direct investment  in the
PRC based on the  registration information provided by  SAFE and its branches.

Under the Circular of the SAFE on Further Improving and Adjusting the Policies  for Foreign
Exchange Administration under Capital  Accounts promulgated by the SAFE on  January 10, 2014  and
effective from February 10, 2014, administration  over the outflow of the profits  by  domestic  institutions
has been further simplified. In principle,  a bank is  no longer  required to examine  transaction
documents when handling the outflow of profits of no  more than  the equivalent of  $50,000 by a
domestic institution. When handling  the  outflow of  profits exceeding the equivalent of $50,000, the
bank, in principle, is no longer required  to  examine the  financial  audit report and  capital verification
report of the domestic institution, provided that  it  must examine, according to the principle of
transaction authenticity, the profit distribution resolution of the board of directors, or the  profit
distribution resolution of the partners, relating to this profit outflow and the original copy of its tax
record-filing form. After each profit outflow, the bank  must  affix its seal to  and endorsements  on the

69

original copy of the relevant tax record-filing form to indicate  the actual amount of  the profit outflow
and the date of the outflow.

On March 30, 2015, SAFE promulgated the Circular  on Reforming the Management Approach

regarding the Settlement of Foreign Exchange  Capital of Foreign-invested Enterprises, or SAFE
Circular 19, which became effective on June  1, 2015. According to SAFE Circular 19, the  foreign
exchange capital of foreign-invested enterprises  may be settled on a  discretionary basis, meaning that
the foreign exchange capital in the capital account of a foreign-invested  enterprise for  which the rights
and interests of monetary contribution  has  been confirmed  by the local foreign exchange  bureau, or  the
book-entry registration of monetary contribution by the banks,  can be settled at  the banks based  on the
actual operational needs of the foreign-invested  enterprise. The proportion of such discretionary
settlement is temporarily determined as  100%.  The  RMB converted from  the foreign exchange capital
will be kept in a designated account,  and if a foreign-invested enterprise needs to make further
payment from such account, it still must  provide supporting documents and go through the review
process with the banks.

Furthermore, SAFE Circular 19 stipulates  that the use  of  capital by foreign-invested  enterprises
must adhere to the principles of authenticity  and  self-use within the  business  scope of enterprises. The
capital of a foreign-invested enterprise and capital in  RMB obtained by the foreign-invested  enterprise
from foreign exchange settlement must  not  be  used  for the  following  purposes:

(1) directly or indirectly used for the payment beyond the business scope of the  enterprises or the

payment prohibited by relevant laws and regulations;

(2) directly or indirectly used for investment in  securities, unless otherwise provided by relevant

laws and regulations;

(3) directly or indirectly used for granting the  entrusted loans in  RMB, unless  permitted by the

scope of business, repaying the inter-enterprise borrowing, including advances by the third
party, or repaying the bank loans in RMB that  have been sub-lent to the third party; and/or

(4) paying the expenses related to the  purchase of real estate that is not for self-use, except for

the foreign-invested real estate enterprises.

On June 19, 2016, SAFE promulgated  the Circular on  Reforming and Regulating Policies  on the
Control  over Foreign Exchange Settlement  of  Capital Accounts, or  Circular 16, which took effect on
the same day. Compared to Circular 19, Circular 16  provides that discretionary foreign exchange
settlement applies to foreign exchange capital, foreign  debt offering proceeds and remitted  foreign
listing proceeds, and the corresponding Renminbi  obtained from foreign exchange settlement  are not
restricted to extending loans to related parties or repaying  the inter-company  loans, including advances
by third parties. However, since Circular  16 came into effect  recently, there are  substantial uncertainties
with respect to its interpretation and implementation in practice.

On January 26, 2017, SAFE promulgated the Circular  on Further Improving Reform  of  Foreign

Exchange Administration and Optimizing  Genuineness and Compliance Verification,  or Circular  3,
which  took effect on the same day. Circular 3 sets  out various  measures with  the following  key
contents:

(1) relaxing the policy restriction on  foreign exchange inflow  to  further enhance trade and

investment facilitation, including (a) expanding the scope of foreign exchange settlement for
domestic foreign exchange loans,  (b) allowing the capital  repatriation for offshore financing
against domestic guarantee, (c) facilitating the centralized management of  foreign exchange
funds of  multinational companies, and (d) allowing  the offshore institutions within pilot  free
trade zones to settle foreign exchange in  domestic foreign exchange  accounts; and

(2) tightening genuineness and compliance verification of cross-border transactions and  cross-

border capital flow, including (a)  improving the statistics of  current account foreign  currency

70

earnings deposited offshore, (b) requiring  banks to verify board resolutions, tax  filing forms,
and audited financial statements before wiring foreign invested enterprises’  foreign exchange
distribution above $50,000, (c) strengthening genuineness and compliance verification  of
foreign direct investments and (d) implementing full scale management of offshore loans in
Renminbi and foreign currencies by requiring the total  amount  of offshore loans be no higher
than 30% of the onshore lender’s equity shown  on its audited financial statements of the last
year.

Our PRC subsidiaries’ distributions to the  offshore parent and their carrying  out cross-border
foreign exchange activities are subject  to  the  various SAFE registration requirements described above.

Share Option Rules

Under the Administration Measures  on Individual Foreign  Exchange Control issued  by  the
People’s Bank of China on December 25,  2006, all foreign  exchange matters involved  in employee
share ownership plans and share option  plans in which PRC citizens participate require approval  from
SAFE or its authorized branch. In addition, under the Notices  on Issues concerning the Foreign
Exchange Administration for Domestic  Individuals  Participating  in Share Incentive Plans of Overseas
Publicly-Listed Companies, or Share Option Rules, issued by the SAFE  on February 15,  2012, PRC
residents who are granted shares or share  options by companies listed  on overseas stock exchanges
under share incentive plans are required to (1) register with the SAFE or its local  branches; (2)  retain
a qualified PRC agent, which may be  a  PRC subsidiary  of  the overseas listed  company or another
qualified institution selected by the PRC subsidiary, to conduct the SAFE registration and other
procedures with respect to the share incentive plans on  behalf of the participants; and  (3) retain an
overseas institution to handle matters  in connection with  their exercise of share options, purchase and
sale of shares or interests and funds transfers.

Regulation of Dividend Distribution

The principal laws, rules and regulations governing dividend distribution by foreign-invested
enterprises in the PRC are the Company  Law of  the PRC, as amended, the Wholly Foreign-owned
Enterprise Law and its implementation  regulations, and the Equity Joint  Venture Law  and its
implementation regulations. Under these laws,  rules and regulations,  foreign-invested enterprises may
pay dividends only out of their accumulated profit, if any, as determined in accordance with  PRC
accounting standards and regulations.  Both  PRC domestic  companies and wholly-foreign owned  PRC
enterprises are required to allocate at  least 10% of their  respective accumulated after-tax profits each
year, if any, to fund certain capital reserve  funds until the aggregate amount  of these  reserve funds
have reached 50% of the registered capital of the  enterprises. A PRC company  is not permitted to
distribute any profits until any losses from prior fiscal years have been offset.  Profits retained from
prior fiscal years may be distributed together  with distributable  profits from  the current fiscal  year.

Labor Laws and Social Insurance

Pursuant to the PRC Labor Law and  the PRC  Labor  Contract Law, employers must execute
written labor contracts with full-time employees. All employers must  comply with  local minimum  wage
standards. Violations of the PRC Labor Contract Law and  the  PRC Labor Law may  result in  the
imposition of fines and other administrative  and criminal liability in the  case of serious  violations.

In addition, according to the PRC Social Insurance Law,  employers like our  PRC subsidiaries in

China must provide employees with welfare schemes covering pension insurance, unemployment
insurance, maternity insurance, work-related injury insurance,  medical insurance, and housing funds.

Rest  of the World Regulation

For other countries besides the United States and the PRC, the requirements governing the

conduct of clinical trials, drug licensing,  pricing and  reimbursement vary from country to country.  In all
cases the clinical trials must be conducted  in accordance  with GCP requirements and  the applicable
regulatory requirements and the ethical  principles having their origin in the Declaration of  Helsinki.

If we  fail to comply with applicable foreign regulatory requirements,  we  may be subject to, among

other things, fines, suspension or withdrawal  of  regulatory approvals, product  recalls, seizure  of
products, operating restrictions and criminal prosecution.

Manufacturing and Supply

We  lease an approximately 140 square meter  manufacturing facility in Beijing, China,  which
produces and supplies preclinical and  clinical trial materials for some  of our  small molecule drug
candidates. In addition, we lease an approximately 11,000 square  meter space and  are building  a
manufacturing facility in Suzhou, China,  where we intend to produce  drug candidates for clinical or, in
the future, commercial use. This facility  consists  of one oral-solid-dosage production line for small
molecule drug products and one pilot plant for monoclonal antibody drug substances.  We also
outsource to a limited number of external service  providers  the production of some  drug substances
and drug products, and we expect to continue to do so  to  meet the preclinical and clinical requirements
of our drug candidates. We have framework  agreements with  most of our external service providers,
under which they generally provide services to us on a short-term and project-by-project basis.

On March 7, 2017, BeiGene (Hong Kong) Co., Limited, our  wholly owned subsidiary, entered  into

a definitive agreement with Guangzhou Development District  and its affiliate Guangzhou GET
Technology Development Co., Ltd to establish a  commercial-scale biologics  manufacturing facility in
Guangzhou, Guangdong Province, China. We  expect to acquire  at  least 100,000 square meters of land
for the manufacturing facility for biologics production.  The joint venture will also provide funding for
research and development of biologic  drug candidates in China. See ‘‘Part  IV—Item  15—Exhibits,
Financial Statement Schedules—Note 22.  Subsequent Events’’ for additional information.

Currently, we obtain raw materials for our manufacturing activities from multiple  suppliers who we
believe have sufficient capacity to meet  our demands. In addition, we  believe that adequate alternative
sources  for such supplies exist. However,  a risk exists that an interruption supplies would materially
harm our business. We typically order raw  materials and  services  on  a  purchase order  basis and do not
enter into long-term dedicated capacity or  minimum  supply arrangements.

Manufacturing is subject to extensive  regulations  that impose various procedural  and
documentation requirements governing record keeping,  manufacturing  processes and controls,
personnel, quality control and quality assurance, among others. Our manufacturing  facilities  and the
contract manufacturing organizations  we use to manufacture our drug  candidates operate under cGMP
conditions. cGMP are regulatory requirements for the  production of pharmaceuticals  that  will be used
in humans. For most of our manufacturing processes a  back-up  cGMP manufacturer is in place  or can
easily be identified.

Employees

As of December 31, 2016, we had 321  full-time employees and one part-time employee. Of these,

267 were engaged  in research and development and laboratory operations and  55 were engaged  in
full-time general and administrative functions. As of December 31, 2016, 268  of  our  employees were
located in the PRC, 49 were located in the  United States and five were  located in Australia. We have
also engaged and may continue to engage independent  contractors to assist us with our operations.
None of our employees are represented  by a labor  union or covered by a collective bargaining

72

agreement. We have never experienced any employment-related  work  stoppages, and we  consider our
relations with our employees to be good.

or histidine residues. These kinases play a  major role in protein and
enzyme regulation as well as signaling  in the  cell.

KRAS . . . . . . . . . . . . . . . KRAS is known as V-Ki-ras2 Kirsten rat sarcoma  viral oncogene

homolog. It is an oncogene that is often mutated in a number of cancers.
The protein product of the normal KRAS gene performs an essential
function in normal tissue signaling, and the mutation of a  KRAS gene is
an essential step in the development of many cancers.

Lesion . . . . . . . . . . . . . . . Means almost any abnormal change involving  any  biological structure,

tissue or organ due to disease or injury,  similar in meaning  to  the word
‘‘damage.’’

PD-1 . . . . . . . . . . . . . . . . Means programmed cell death protein 1, an immune checkpoint receptor

expressed on T-cells and pro-B-cells that binds  two ligands, PD-L1 and
PD-L2. PD-1 is a cell

surface receptor that plays an important role  in down-regulating the
immune system by preventing the activation of T-cells.

PD-L1 . . . . . . . . . . . . . . . Means programmed death-ligand 1, a  protein in humans encoded by  the

CD274 gene. PD-L1 binds the PD-1 receptor and sends an inhibitory
signal inside the T-cell, stopping it from  making more poisonous proteins
and killing the cells that send the signal via PD-L1 and in the
neighborhood.

PDX . . . . . . . . . . . . . . . . Means patient-derived xenograft, created when the cancerous  tissue  from

Item 1A. Risk Factors

The following section includes the most significant  factors that may adversely affect our  business  and
operations. You should carefully consider the risks and  uncertainties  described  below and all information
contained in this Annual Report, including our financial statements and  the related notes and ‘‘Part II—
Item 7—Management’s Discussion and Analysis  of  Financial Condition  and Results  of  Operations,’’ before
deciding to invest in the ADSs. The occurrence of any of the events or developments  described below could
harm our business, financial condition,  results  of  operations  and growth prospects. In such an event,  the
market price of the ADSs could decline  and  you may  lose all or  part of your investment. Additional risks
and uncertainties not presently known to us or that we currently deem immaterial also  may impair our
business operations

Risks Related to Our Financial Position  and Need  for Additional  Capital

We are a globally focused biopharmaceutical  company  and have a limited operating history,  which  may make
it difficult to evaluate our current business and predict our future performance.

We  are a globally focused biopharmaceutical company formed  in October  2010. Our  operations to

date  have focused on organizing and staffing our company, business planning,  raising  capital,
establishing our intellectual property portfolio  and  conducting preclinical  studies and clinical trials of
our  current drug candidates, such as  BGB-3111,  BGB-A317, BGB-290  and BGB-283. We have  not  yet
demonstrated an ability to initiate or successfully complete  large-scale, pivotal clinical  trials, obtain
regulatory approvals, manufacture a  commercial  scale drug, or arrange for a  third party  to  do so  on our
behalf, or conduct sales and marketing  activities necessary for successful commercialization. We have
not yet obtained regulatory approval for, or  demonstrated an  ability  to  commercialize, any of our drug
candidates. We have no products approved for commercial sale and have not generated  any revenue
from product sales. Consequently, any  predictions you make about our  future success  or viability  may
not be as accurate as they could be if  we had  a longer  operating history. In addition, as  a new  business,
we may encounter unforeseen expenses, difficulties,  complications, delays and other known and
unknown factors.

We  are focused on the discovery and  development  of  innovative,  molecularly  targeted  and

immuno-oncology drugs for the treatment of cancers. Our limited operating history, particularly  in light
of the rapidly evolving cancer treatment  field, may make it difficult to evaluate  our current business
and predict our future performance.  Our  short  history  makes any assessment of our future  success or
viability subject to  significant uncertainty. We will encounter  risks and difficulties frequently
experienced by early-stage companies  in  rapidly evolving  fields  as we seek  to  transition  to  a company
capable of supporting commercial activities. If we  do  not  address these  risks and  difficulties
successfully, our business will suffer.

We have  incurred net losses in each period since our inception and anticipate that  we will  continue  to incur
net losses for the foreseeable future.

Investment in pharmaceutical product development is highly speculative because  it entails
substantial upfront capital expenditures  and significant risk that  a drug candidate  will  fail to gain
regulatory approval or become commercially viable.  We  have devoted most of our financial resources to
research and development, including  our nonclinical  development activities and clinical trials. We have
not generated any revenue from product  sales to date, and we continue to incur significant
development and other expenses related to our ongoing operations.  As a result, we are not profitable
and have incurred losses in each period  since our inception  in 2010. We reported a  net loss  of
$119.2 million, $57.1 million and $18.5  million, respectively, for the years ended December 31, 2016,
2015 and 2014. As of December 31, 2016, we had a deficit  accumulated of $237.4 million. Substantially

78

all of our operating losses have resulted from  costs incurred in connection with our research and
development programs and from general and administrative costs associated with  our  operations.

We  expect to continue to incur losses  for the foreseeable future,  and  we expect these  losses to

increase as we continue our development of, and seek regulatory approvals for, our drug candidates,
and begin to commercialize approved drugs, if  any. Typically, it  takes many years to develop one new
drug from the time it is discovered to  when it is available  for treating patients. We  may encounter
unforeseen expenses, difficulties, complications, delays and  other unknown factors that may adversely
affect our business. The size of our future  net losses will depend, in part, on the rate of future  growth
of our expenses, our ability to generate revenues and the timing  and  amount of  milestones and other
required payments to third parties in  connection with our  potential  future  arrangements with third
parties. If any of our drug candidates fail  in clinical trials or do  not  gain regulatory  approval, or if
approved, fail to achieve market acceptance, we may never become profitable.  Even if we achieve
profitability in the future, we may not be able to sustain  profitability in  subsequent periods.  Our prior
losses and expected future losses have had, and will continue  to  have, an adverse effect  on our
shareholders’ equity and working capital.

We  expect our research and development expenses to continue to be significant  in connection with
our  continued investment in our cancer  biology platform and our  ongoing and planned clinical  trials for
our  drug candidates, such as BGB-3111,  BGB-A317, BGB-290 and BGB-283. Furthermore, if we
obtain regulatory approval for our drug  candidates, we expect  to  incur increased  sales and marketing
expenses. In addition, we will incur additional costs  associated with  operating as  a public  company. As
a result, we expect to continue to incur  significant and increasing operating losses and negative cash
flows for the foreseeable future. These losses have  had and will continue  to  have a material adverse
effect on our shareholders’ deficit, financial position, cash flows and  working  capital.

We currently do not generate revenue from  product sales and  may  never become profitable.

Our ability to generate revenue and become profitable  depends upon our ability to successfully

complete the development of, and obtain the  necessary regulatory  approvals for,  our  drug  candidates,
such as BGB-3111, BGB-A317, BGB-290  and BGB-283, as we do not currently have any drugs that are
available for commercial sale. We expect  to  continue to incur substantial and increasing  losses through
the projected commercialization of our drug  candidates. None of our drug  candidates have been
approved for marketing in the United States,  the European  Union, the People’s Republic of China, or
PRC, or any other jurisdiction and may  never receive such approval. Our  ability to achieve revenue  and
profitability is dependent on our ability to complete the development  of our  drug candidates, obtain
necessary regulatory approvals, and have our drugs manufactured and successfully  marketed.

Even if we receive regulatory approval of  our drug  candidates for commercial sale, we do  not
know when they will generate revenue,  if at all. Our ability to generate product sales  revenue depends
on a number  of factors, including our ability to continue:

(cid:129) completing research regarding, and  nonclinical and clinical development of, our drug candidates;

(cid:129) obtaining regulatory approvals and  marketing  authorizations for drug candidates for  which we

complete clinical trials;

(cid:129) obtaining adequate reimbursement from third-party payors, including government payors;

(cid:129) developing a sustainable and scalable manufacturing process for our drug candidates,  including
establishing and maintaining commercially viable supply relationships  with third parties  and
establishing our own manufacturing capabilities and infrastructure;

(cid:129) launching and commercializing drug  candidates for which  we obtain regulatory approvals and

marketing authorizations, either directly  or with  a collaborator  or distributor;

79

(cid:129) obtaining market acceptance of our drug candidates  as viable treatment options;

(cid:129) identifying, assessing, acquiring and/or developing new  drug  candidates;

(cid:129) addressing any competing technological and  market  developments;

(cid:129) negotiating and maintaining favorable terms in any collaboration, licensing or  other

arrangements into which we may enter, such  as our collaboration arrangements with Merck
KGaA, Darmstadt Germany;

(cid:129) maintaining, protecting and expanding our  portfolio of intellectual property rights, including

patents, trade secrets and know-how; and

(cid:129) attracting, hiring and retaining qualified personnel.

In addition, because of the numerous risks and uncertainties associated with drug development, we

are unable to predict the timing or amount  of increased expenses, or when, or  if,  we will be able to
achieve or maintain profitability. In addition,  our  expenses could increase beyond  expectations if we  are
required by the FDA; the CFDA; the EMA;  or other comparable regulatory  authorities to perform
studies in addition to those that we currently anticipate. Even  if our  drug  candidates are  approved for
commercial sale, we anticipate incurring significant costs  associated  with the  commercial launch of
these drugs.

Our ability to become and remain profitable depends  on our ability  to  generate revenue.  Even if
we are able to generate revenues from  the sale  of  our  potential  drugs, we  may not become  profitable
and may need to obtain additional funding to continue operations. If we fail  to  become profitable or
are unable to sustain profitability on a continuing basis, then we may be unable  to  continue our
operations at planned levels and be forced  to  reduce our operations.  Even if we do achieve
profitability, we may not be able to sustain or increase profitability  on a quarterly or annual  basis. Our
failure to become and remain profitable would decrease the  value  of our  company and could impair
our  ability to raise capital, expand our  business or continue our  operations. Failure to become and
remain profitable may adversely affect the market price  of  the ADSs  and our ability to raise  capital and
continue operations.

We will need to obtain additional financing  to fund our operations, and if we are  unable to obtain such
financing, we may be unable to complete the  development  and  commercialization  of  our primary drug
candidates.

We  have financed our operations with a  combination  of equity and  debt  offerings,  contracts, and

private  and public grants. Through December  31, 2016, we raised approximately $170 million in private
equity financing and $10 million in non-convertible debt financings. To date,  we have received a  total of
$37 million in upfront payments and  milestone payments through our  collaboration arrangements with
Merck KGaA, Darmstadt Germany for BGB-283  and BGB-290. On February 8, 2016  and
November 23, 2016, we completed our  initial public offering and follow-on public offering of the ADSs
and received net proceeds of $166.2 million  and  $198.6 million,  respectively, after  deducting
underwriting discount and offering expenses. Our drug candidates will  require  the completion of
regulatory review,  significant marketing efforts and substantial  investment  before  they can provide us
with any product sales revenue.

Our operations have consumed substantial amounts  of cash  since inception. Our operating
activities used $89.5 million, $39.8 million  and  $8.7 million  of  net cash during the years ended
December 31, 2016, 2015 and 2014, respectively. We expect to continue  to  spend  substantial amounts
on drug discovery advancing the clinical development of our drug candidates, and  launching and
commercializing any drug candidates for  which we receive regulatory approval,  including building our
own commercial organizations to address certain  markets.

We  will need to obtain additional financing to fund our future  operations,  including completing the

development and commercialization of our primary drug candidates: BGB-3111, BGB-A317,  BGB-290
and BGB-283. We will need to obtain additional financing to conduct additional clinical  trials for  the
approval of our drug candidates if requested  by  regulatory bodies, and completing the development of
any additional drug candidates we might discover.  Moreover,  our fixed expenses such as rent, interest
expense and other contractual commitments are  substantial and are expected to increase  in the future.

Our forecast of the period of time through which  our financial resources  will  be  adequate to
support our operations is a forward-looking statement and involves risks and uncertainties,  and actual
results could vary as a result of a number  of  factors, including the factors discussed elsewhere in this
‘‘Risk Factors’’ section. 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, but not limited to:

(cid:129) the progress, timing, scope and costs of our  clinical trials, including  the ability to timely enroll

patients in our planned and potential future clinical trials;

(cid:129) the outcome, timing and cost of regulatory  approvals by the FDA, CFDA, EMA  and comparable

regulatory authorities, including the potential  that the FDA,  CFDA,  EMA or comparable
regulatory authorities may require that we perform more studies than those that we  currently
expect;

(cid:129) the number and characteristics of drug candidates that we may in-license and  develop;

(cid:129) our ability to successfully commercialize our drug candidates;

(cid:129) the amount of sales and other revenues  from drug candidates  that we may  commercialize, if any,
including the selling prices for such potential products and the availability  of  adequate third-
party reimbursement;

(cid:129) the amount and timing of the milestone and  royalty payments we receive from our collaborators

under our licensing arrangements, such as our  collaboration with  Merck  KGaA, Darmstadt
Germany;

(cid:129) the cost of filing, prosecuting, defending and enforcing  any patent  claims  and other  intellectual

property rights;

(cid:129) selling and marketing costs associated with  our  potential products, including the cost and  timing

of expanding our marketing and sales capabilities;

(cid:129) the terms and timing of any potential future collaborations, licensing or other arrangements that

we may establish;

(cid:129) cash requirements of any future acquisitions and/or the  development of other drug candidates;

(cid:129) the costs of operating as a public company;

(cid:129) the cost and timing of completion of commercial-scale  outsourced manufacturing activities;

(cid:129) the time and cost necessary to respond  to  technological and market developments;  and

(cid:129) the costs of filing, prosecuting, defending and enforcing any patent  claims and  other intellectual

property rights.

Until we can generate a sufficient amount of revenue, we may finance future  cash needs through

public or private equity offerings, license agreements, debt financings, collaborations, strategic alliances
and marketing or distribution arrangements. Additional  funds  may not be available  when we need them
on terms that are acceptable to us, or  at  all. General market conditions  or  the market price of the
ADSs may not support capital raising  transactions such  as an additional public or private offering  of

81

the ADSs or other securities. In addition,  our ability to raise additional capital may be dependent upon
the ADSs being quoted on the NASDAQ  or upon obtaining shareholder approval.  There can  be  no
assurance that we will be able to satisfy the  criteria for  continued listing on the NASDAQ or that we
will be able to obtain shareholder approval if it is necessary. If  adequate funds are not available,  we
may be required to delay or reduce the  scope of or  eliminate one or more of  our research or
development programs or our commercialization  efforts. We may seek to access the public or  private
capital markets whenever conditions  are  favorable, even if we do not have an  immediate need  for
additional capital at that time. In addition, if  we raise additional funds  through collaborations, strategic
alliances or marketing, distribution or  licensing arrangements  with third parties, we may have to
relinquish valuable rights to our technologies,  future revenue streams or drug candidates or  to  grant
licenses on terms that may not be favorable  to  us.

We  believe that our existing cash and  cash equivalents, will not be sufficient to enable  us to
complete all necessary global development or commercially launch our  current drug candidates.
Accordingly, we will require further funding  through other public or private offerings, debt financing,
collaboration and licensing arrangements or  other sources. Adequate additional funding may not be
available to us on acceptable terms, or at all.  If we are unable to raise capital  when needed or on
attractive terms, we would be forced  to  delay, reduce or eliminate our research and development
programs or future commercialization  efforts. Our inability to obtain additional funding when  we need
it could seriously harm our business.

Raising additional capital may cause dilution  to our shareholders,  restrict our  operations or  require us  to
relinquish rights to our technologies or drug  candidates.

We  may seek additional funding through a  combination of equity  offerings, debt financings,
collaborations and licensing arrangements.  To the  extent that we  raise additional capital through the
sale of equity or convertible debt securities, your  ownership interest  will be diluted, and the terms  may
include liquidation or other preferences that  adversely affect  your rights as a holder of the  ADSs or
our  ordinary shares. The incurrence of additional indebtedness  or the issuance of certain equity
securities could result in increased fixed payment obligations and could also result in certain additional
restrictive covenants, such as limitations  on our ability to incur additional  debt  or issue  additional
equity, limitations  on our ability to acquire or license intellectual property rights and other operating
restrictions that could adversely impact  our  ability to conduct our  business.  In addition, issuance of
additional equity securities, or the possibility  of such issuance, may cause the market  price of the ADSs
to decline. In the event that we enter  into  collaborations or licensing  arrangements in  order to raise
capital, we may be required to accept unfavorable terms, including  relinquishing or licensing to a  third
party on unfavorable terms our rights to technologies or  drug candidates that we otherwise would seek
to develop or commercialize ourselves  or  potentially  reserve for future potential arrangements  when we
might be able to achieve more favorable terms.

Fluctuations in exchange rates could result  in foreign currency  exchange losses and could materially reduce
the value of your investment.

We  incur portions of our expenses, and may in the future derive  revenues, in currencies other than

the U.S.  dollar, in particular, the RMB and Australian dollars. As a result, we are exposed to foreign
currency exchange risk as our results  of operations and cash flows are subject  to  fluctuations in foreign
currency exchange rates. For example,  a  significant  portion of our clinical trial activities  are conducted
outside of the United States, and associated  costs may be incurred in the  local currency of the  country
in which the trial is being conducted, which costs  could  be subject  to  fluctuations in  currency  exchange
rates. We currently do not engage in hedging transactions to protect against uncertainty in future
exchange rates between particular foreign  currencies and the U.S. dollar.  A decline in  the value  of  the
U.S. dollar against currencies in countries in which we conduct clinical  trials could have a  negative

82

impact on our research and development costs. We cannot predict  the  impact  of foreign currency
fluctuations, and foreign currency fluctuations  in the future may  adversely affect our financial condition,
results of operations and cash flows.

The value of the RMB against the U.S. dollar  and  other  currencies may fluctuate  and is affected
by, among other things, changes in political and  economic  conditions and the  foreign exchange  policy
adopted by the PRC, Australia and other non-U.S. governments. Specifically in  the PRC, on July 21,
2005, the PRC government changed its  policy of pegging the value of the  RMB to the U.S. dollar.
Following the removal of the U.S. dollar peg, the RMB appreciated  more  than 20%  against the U.S.
dollar over the following three years.  Between July  2008 and  June 2010, this appreciation halted and
the exchange rate between the RMB and the U.S. dollar  remained within a narrow band.  Since June
2010, the PRC government has allowed the RMB to appreciate slowly against the  U.S. dollar  again,
and it has appreciated more than 10% since June 2010. In April 2012, the PRC government announced
that it would allow more RMB exchange rate fluctuation.  On August 11,  2015, China’s central bank
executed a 2% devaluation in the RMB.  Over the following two days, Chinese  currency  fell  3.5%
against the dollar. However, it remains  unclear what  further fluctuations may occur or what  impact  this
will have on the currency.

It  is difficult to predict how market forces or PRC,  Australian, U.S. or other government policies

may impact the exchange rate between the Australian  dollar, RMB, U.S.  dollar and other currencies in
the future. There remains significant  international pressure on the PRC government  to  adopt a  more
flexible currency policy, which could result in  greater  fluctuation of  the  RMB against  the U.S.  dollar.
Substantially all of our revenues are denominated in U.S. dollars  and our costs  are denominated in
U.S. dollars, Australian dollars and RMB,  and a  large portion of our financial assets and  a significant
portion of our debt is denominated in U.S. dollars.  Any  significant revaluation of the  RMB may
materially reduce any dividends payable  on the  ADSs in U.S. dollars. To the extent  that  we need to
convert U.S. dollars we received from our initial public offering and follow-on public offering  into
RMB for our operations, appreciation  of  the  RMB against the U.S. dollar would have  an adverse effect
on the RMB amount we would receive.  Conversely, if we decide  to  convert  our RMB into U.S.  dollars
for the purpose of making payments for dividends on our ordinary shares or  ADSs or for other
business purposes, appreciation of the U.S.  dollar against the RMB  would have a negative effect  on the
U.S. dollar amount we would receive.

Our investments are subject to risks that  could result in losses.

We  had cash and cash equivalents of  $87.5 million, $17.9  million  and  $13.9 million  and short-term

investments of $280.7 million, $82.6 million  and  $30.5 million  at  December 31, 2016, 2015 and 2014,
respectively. At December 31, 2016,  our short-term investments  mainly consisted of U.S. Treasury
securities. On February 8, 2016 and November 23,  2016, we completed our initial  public  offering and
follow-on public offering of the ADSs and received net proceeds  of  $166.2 million and $198.6 million,
respectively, after deducting underwriting discount and offering  expenses. We may invest our cash  in a
variety of financial instruments, principally securities issued by the  U.S.  government and  its  agencies,
investment grade corporate bonds, including commercial paper and money market instruments, which
may not yield a favorable return to our shareholders. All  of  these investments are subject  to  credit,
liquidity, market and interest rate risk.  Such risks, including  the failure  or  severe financial  distress of
the financial institutions that hold our  cash, cash equivalents and investments, may result in a  loss of
liquidity, impairment to our investments, realization of substantial  future  losses, or a complete  loss of
the investments in the long-term, which may have a  material  adverse effect on our  business,  results of
operations, liquidity and financial condition.  Our primary exposure to market risk  relates to fluctuations
in the interest rates of the PRC and  the  United States. In order to manage the risk to our investments,
we maintain an investment policy that, among other things, limits the amount that we may invest in  any
one issue or any single issuer and requires us to only invest in high  credit quality securities.  While  we

83

believe our cash and cash equivalents  do  not contain excessive risk, we cannot provide  absolute
assurance that in the future investments will not be subject to adverse changes in market value.

Risks Related to Clinical Development of  Our Drug Candidates

We depend substantially on the success of our drug  candidates, particularly BGB-3111, BGB-A317, BGB-290
and BGB-283, which are in clinical development. Clinical trials of  our  drug candidates may not be successful.
If we are unable to commercialize our  drug  candidates,  or experience significant  delays in doing so, our
business will be materially harmed.

Our business and the ability to generate revenue related  to product sales, if ever, will depend on
the successful development, regulatory approval and commercialization of our drug candidates  for the
treatment of patients with cancer, particularly BGB-3111,  BGB-A317,  BGB-290 and BGB-283,  which
are still in development, and other drugs  we may develop.  We have invested  a significant  portion of our
efforts and financial resources in the  development of our existing  drug  candidates. The success of our
drug candidates, including BGB-3111, BGB-A317, BGB-290 and BGB-283, will depend on  several
factors, including:

(cid:129) successful enrollment in, and completion of, preclinical studies and clinical trials;

(cid:129) receipt of regulatory approvals from  the FDA, CFDA, EMA and  other comparable regulatory

authorities for our drug candidates, including our companion diagnostics;

(cid:129) establishing commercial manufacturing capabilities, either by building facilities ourselves or

making arrangements with third-party manufacturers;

(cid:129) relying on third parties to conduct our clinical trials safely and efficiently;

(cid:129) obtaining and maintaining patent, trade secret and other  intellectual property protection and

regulatory exclusivity;

(cid:129) protecting our rights in our intellectual property;

(cid:129) ensuring we do not infringe, misappropriate  or otherwise  violate the  patent,  trade secret  or other

intellectual property rights of third parties;

(cid:129) launching commercial sales of our  drug candidates,  if  and when approved;

(cid:129) obtaining reimbursement from third-party payors for drug candidates,  if  and when approved;

(cid:129) competition with other drug candidates  and drugs;

(cid:129) continued acceptable safety profile  for our drug candidates  following  regulatory approval,  if  and

when received; and

(cid:129) obtaining sufficient supplies of any  competitor drug  products  that may  be  necessary  for use in

clinical trials for evaluation of our drug candidates.

If we  do not achieve one or more of  these factors in a timely  manner  or  at all, we could

experience significant delays in our ability  to  obtain  approval for and/or  to  successfully  commercialize
our  drug candidates, which would materially  harm our business and we may  not  be  able to generate
sufficient revenues and cash flows to continue our operations.

We may  not be successful in our efforts to identify or discover  additional drug candidates. Due  to our limited
resources and  access to capital, we must  and have  in  the past  decided to prioritize  development of  certain drug
candidates; these decisions may prove to  have been wrong  and may adversely affect our business.

Although we intend to explore other  therapeutic opportunities with our cancer biology platform in

addition to the drug candidates that we  are  currently developing,  we may fail to identify other drug

84

candidates for clinical development for a  number of reasons. For example, our research methodology
may be unsuccessful in identifying potential drug  candidates or those  we  identify may  be  shown to have
harmful side effects or other characteristics that  make them unmarketable or unlikely to receive
regulatory approval. Specifically, we  have focused on developing our cancer biology platform, which
enables us to test a large panel of tumor  models for sensitivity to the drug  candidates we  generated,
identify targets to pursue, identify drug-resistance mechanisms, explore combination strategies and
regimens, and improve our understanding of the contributions  of tumor micro, or macro-environment
in cancer treatments. If our cancer biology platform fails to identify potential drug  candidates, our
business could be materially harmed.

Research programs to pursue the development  of  our  drug candidates for additional indications

and to identify new drug candidates and  disease targets require substantial technical, financial and
human resources whether or not we ultimately are successful.  Our research programs may initially show
promise in identifying potential indications  and/or drug candidates, yet fail to yield results  for clinical
development for a number of reasons,  including:

(cid:129) the research methodology used may  not  be  successful in identifying potential indications and/or

drug candidates;

(cid:129) potential drug candidates may, after further  study, be shown  to  have harmful adverse effects  or

other characteristics that indicate they are unlikely  to  be  effective drugs; or

(cid:129) it may  take greater human and financial resources to identify  additional therapeutic

opportunities for our drug candidates or  to  develop  suitable  potential drug candidates through
internal research programs than we will  possess,  thereby  limiting  our ability to diversify and
expand our drug portfolio.

Because we have limited financial and  managerial  resources, we focus  on research programs and
drug candidates for specific indications. As a  result, we  may  forego or delay pursuit  of  opportunities
with other drug candidates or for other  indications that  later prove to have greater commercial
potential or a greater likelihood of success. Our resource allocation decisions  may cause  us to fail to
capitalize on viable commercial products or profitable market opportunities.

Accordingly, there can be no assurance that we will ever be able to identify additional therapeutic
opportunities for our drug candidates or  to  develop  suitable  potential drug candidates through  internal
research programs, which could materially  adversely affect  our future growth  and prospects. We may
focus our efforts and resources on potential drug candidates  or other potential programs that ultimately
prove to be unsuccessful.

If we encounter difficulties enrolling patients  in  our  clinical trials, our  clinical  development  activities could  be
delayed or otherwise adversely affected.

The timely completion of clinical trials in accordance  with their protocols depends, among other

things, on our ability to enroll a sufficient  number of patients who remain in  the trial until its
conclusion. We may experience difficulties in patient enrollment in our  clinical trials for a variety of
reasons, including:

(cid:129) the size and nature of the patient population;

(cid:129) the patient eligibility criteria defined in  the protocol;

(cid:129) the size of the study population required  for  analysis of the trial’s primary endpoints;

(cid:129) the proximity of patients to trial sites;

(cid:129) the design of the trial;

85

(cid:129) our ability to recruit clinical trial investigators  with the appropriate  competencies  and

experience;

(cid:129) competing clinical trials for similar  therapies  or other new therapeutics;

(cid:129) clinicians’ and patients’ perceptions  as to the potential advantages  and  side effects of the drug
candidate being studied in relation to other  available therapies,  including any new  drugs or
treatments that may be approved for the indications we are investigating;

(cid:129) our ability to obtain and maintain patient  consents;

(cid:129) the risk that patients enrolled in clinical  trials will not complete a clinical trial; and

(cid:129) the availability of approved therapies that are  similar in mechanism  to  our drug  candidates.

In addition, our clinical trials will compete  with other clinical trials  for drug  candidates that are in

the same therapeutic areas as our drug candidates, such as  BGB-3111,  BGB-A317, BGB-290  and
BGB-283, and this competition will reduce the number and  types of patients available to us, because
some patients who might have opted to enroll  in our trials may  instead opt  to  enroll in  a trial being
conducted by one of our competitors. Because the number of  qualified clinical investigators is limited,
we expect to conduct some of our clinical trials at the same clinical trial  sites that some  of  our
competitors use, which will reduce the  number of patients  who are  available for  our clinical trials at
such clinical trial sites.

Even if we are able to enroll a sufficient number of patients  in our clinical  trials, delays  in patient

enrollment may result in increased costs  or may  affect the  timing or outcome of  the planned clinical
trials, which could prevent completion of  these trials and adversely  affect our ability to advance the
development of our drug candidates.

Some of our drug candidates represent a novel approach  to cancer treatment that could result in  delays in
clinical development, heightened regulatory  scrutiny, or delays in our ability to  achieve regulatory approval or
commercialization of our drug candidates.

Some of  our drug candidates represent a  departure from more  commonly used  methods for cancer
treatment, and therefore represent a novel approach that carries inherent development risks. The need
to further develop or modify in any way the protocols related to our drug candidates  to  demonstrate
safety or efficacy may delay the clinical  program, regulatory approval or  commercialization, if approved.
In addition, potential patients and their doctors may be inclined to use  conventional standard-of-care
treatments rather than enroll patients  in  any future clinical trial. This may have a  material  impact  on
our  ability to generate revenues from  our  drug candidates. Further, given the  novelty of our drug
candidates, the end users and medical personnel  may  require a  substantial amount of education and
training.

Clinical drug development involves a lengthy  and expensive process  with an uncertain outcome, and  results of
earlier studies and trials may not be predictive of future trial results.

Clinical testing is expensive and can take many years to complete, and its outcome is inherently

uncertain. Failure can occur at any time  during the clinical trial process. The results of preclinical
studies and early clinical trials of our drug candidates may not  be  predictive of the results of later-stage
clinical trials. Drug candidates in later  stages  of  clinical  trials may fail to show the  desired  safety and
efficacy traits despite having progressed  through  preclinical studies  and  initial clinical  trials. In some
instances, there can be significant variability  in safety and/or efficacy results  between  different  trials of
the same drug candidate due to numerous factors, including  changes in trial  procedures  set forth in
protocols, differences in the size and type  of  the patient populations, including genetic  differences,
patient adherence to the dosing regimen  and other trial protocols and the rate of dropout among

86

clinical trial participants. In the case  of  any trials we conduct,  results may  differ  from earlier trials  due
to the larger number of clinical trial sites  and additional countries and languages involved  in such trials.
A number of companies in the pharmaceutical and biotechnology industries have suffered significant
setbacks in advanced clinical trials due  to  lack of efficacy  or  adverse safety profiles, notwithstanding
promising results in earlier trials. Our future clinical trial results may not be favorable.

If clinical trials of our drug candidates  fail  to  demonstrate safety and efficacy to the satisfaction  of  the FDA,
CFDA, EMA or other comparable regulatory  authorities  or do  not  otherwise produce positive results,  we may
incur additional costs or experience delays  in  completing, or  ultimately be  unable  to complete, the development
and commercialization of our drug candidates.

Before obtaining regulatory approval  for the  sale of our  drug  candidates, such  as BGB-3111,
BGB-A317, BGB-290 and BGB-283, we  must conduct extensive clinical trials to demonstrate the  safety
and efficacy of our drug candidates in  humans. Clinical testing is expensive, difficult to design and
implement, can take many years to complete and is uncertain  as to outcome. A failure of one or  more
of our clinical trials can occur at any  stage of testing. The outcome of preclinical  testing and early
clinical trials may not be predictive of the  success of later clinical  trials, and successful  interim results
of a clinical trial do not necessarily predict successful final results.

We  may experience numerous unexpected events  during,  or as  a  result of, clinical trials that could

delay or prevent our ability to receive  regulatory approval or commercialize  our drug  candidates,
including:

(cid:129) regulators, IRBs, or ethics committees  may not authorize  us or our  investigators to commence a

clinical trial or conduct a clinical trial at a prospective  trial site;

(cid:129) clinical trials of our drug candidates may  produce negative or inconclusive results, and we may

decide, or regulators may require us,  to  conduct additional clinical  trials or abandon drug
development programs;

(cid:129) the number of patients required for  clinical trials  of our drug candidates may  be  larger  than we
anticipate, enrollment may be insufficient  or slower than we  anticipate or patients  may drop out
at a higher rate than we anticipate;

(cid:129) our third-party contractors may fail to comply with  regulatory requirements or meet  their

contractual obligations to us in a timely manner, or at all;

(cid:129) we might have to suspend or terminate clinical trials of  our drug  candidates for various reasons,
including a finding of a lack of clinical response or a  finding that participants are being exposed
to unacceptable health risks;

(cid:129) regulators, IRBs or ethics committees  may require that we or  our investigators suspend or
terminate clinical research for various reasons, including noncompliance  with regulatory
requirements;

(cid:129) the cost of clinical trials of our drug candidates may be greater  than we anticipate;

(cid:129) the supply or quality of our drug candidates, companion diagnostics or  other materials necessary

to conduct clinical trials of our drug candidates may  be  insufficient or  inadequate; and

(cid:129) our drug candidates may cause AEs, have undesirable side  effects or other unexpected

characteristics, causing us or our investigators to suspend or  terminate  the trials.

87

If we  are required to conduct additional  clinical trials  or other testing of  our drug candidates
beyond those that we currently contemplate, if  we are  unable to successfully complete clinical trials of
our  drug candidates or other testing, if the  results of these trials  or  tests are not positive  or are only
modestly positive or if they raise safety  concerns,  we may:

(cid:129) be delayed in obtaining regulatory approval for  our drug candidates;

(cid:129) not obtain regulatory approval at all;

(cid:129) obtain approval for indications that  are  not  as broad  as intended;

(cid:129) have the drug removed from the market after obtaining regulatory approval;

(cid:129) be subject to additional post-marketing  testing requirements;

(cid:129) be subject to restrictions on how the drug is distributed or used;  or

(cid:129) be unable to obtain reimbursement for use of the drug.

Delays in testing or approvals may result in increases  in our drug development costs. We do not
know whether any clinical trials will begin  as planned, will  need  to  be  restructured  or will be completed
on schedule, or at all.

Significant clinical trial delays also could shorten any periods during which  we have the  exclusive
right to commercialize our drug candidates or allow  our competitors  to  bring  drugs to market before
we do and impair  our ability to commercialize our  drug  candidates and may harm  our business and
results of operations.

Risks Related to Obtaining Regulatory Approval for Our  Drug Candidates

The regulatory approval processes of the FDA,  CFDA, EMA and  other comparable regulatory authorities are
lengthy, time consuming and inherently  unpredictable, and if we are  ultimately unable to  obtain regulatory
approval for our drug candidates, our business will be  substantially harmed.

The time required to obtain approval  by  the FDA, CFDA, EMA and other  comparable  regulatory

authorities is unpredictable but typically takes many years following the  commencement of preclinical
studies and clinical trials and depends upon numerous  factors,  including the substantial discretion of
the regulatory authorities. In addition,  approval policies, regulations or the type and amount of clinical
data necessary to gain approval may  change during the course of a  drug  candidate’s clinical
development and may vary among jurisdictions. We have  not  obtained regulatory approval  for any drug
candidate, and it is possible that none  of  our existing  drug candidates or any drug  candidates we  may
discover, in-license or acquire and seek  to develop in the  future will ever  obtain regulatory approval.

Our drug candidates could fail to receive regulatory approval from the FDA,  CFDA,  EMA or a

comparable regulatory authority for many reasons, including:

(cid:129) disagreement with the design or implementation  of our clinical trials;

(cid:129) failure to demonstrate that a drug  candidate is safe and effective or that a  biologic drug

candidate is safe, pure, and potent for  its proposed indication;

(cid:129) failure of clinical trial results to meet the level of statistical significance required for  approval;

(cid:129) failure to demonstrate that a drug  candidate’s clinical and other  benefits  outweigh its safety

risks;

(cid:129) disagreement with our interpretation  of  data from preclinical studies or clinical trials;

(cid:129) the insufficiency of data collected from clinical trials of our  drug  candidates to support  the

submission and filing of a NDA; or BLA; or other submission or to obtain regulatory approval;

88

(cid:129) the FDA, CFDA, EMA or comparable regulatory authority’s finding of  deficiencies related to

the manufacturing processes or facilities  of  third-party manufacturers with whom we  contract for
clinical and commercial supplies; and

(cid:129) changes in approval policies or regulations  that render our preclinical and clinical data

insufficient for approval.

The FDA, CFDA, EMA or a comparable regulatory authority may  require  more information,

including additional preclinical or clinical data,  to  support approval, which may delay or prevent
approval and our commercialization  plans, or we may decide  to  abandon the development program. If
we were to obtain approval, regulatory authorities  may  approve any of our drug candidates for fewer or
more limited indications than we request, may  grant approval contingent  on the  performance of costly
post-marketing clinical trials, or may  approve a  drug  candidate with  a label  that  is not desirable  for the
successful commercialization of that drug  candidate. In addition, if our drug candidate  produces
undesirable side effects or safety issues, the FDA may  require  the establishment of a Risk  Evaluation
Mitigation Strategy, or REMS, or the  CFDA, EMA or a  comparable regulatory authority may require
the establishment of a similar strategy,  that may,  for instance, restrict distribution of our drugs and
impose burdensome implementation requirements on us. Any  of the foregoing scenarios could
materially harm the commercial prospects  of  our  drug candidates.

Regulatory approval may be substantially  delayed or  may not be obtained for  one or all  of  our drug
candidates if regulatory authorities require additional time or studies to assess the  safety and efficacy of our
drug candidates.

We  may be unable to initiate or complete  development of our drug candidates, such as  BGB-3111,
BGB-A317, BGB-290 and BGB-283, on  schedule, if at all. The timing for the  completion  of  the studies
for our  drug candidates will require funding beyond the  proceeds of our initial public offering  and
follow-on public offering. In addition, if  regulatory authorities require  additional time  or studies  to
assess the safety or efficacy of our drug candidates,  we may not have or be able to obtain adequate
funding to complete the necessary steps  for approval for any or all  of  our drug  candidates. Preclinical
studies and clinical trials required to  demonstrate the safety and efficacy of our drug candidates are
time consuming and expensive and together take several  years or more to complete.  Delays in clinical
trials, regulatory approvals or rejections  of  applications  for regulatory  approval  in the United States,
Australia, New Zealand, the PRC, Europe  or other markets may result from many  factors, including:

(cid:129) our inability to obtain sufficient funds required for a clinical trial;

(cid:129) regulatory requests for additional analyses, reports, data, nonclinical and preclinical studies and

clinical trials;

(cid:129) regulatory questions regarding interpretations  of data and results and the emergence of new

information regarding our drug candidates  or other products;

(cid:129) clinical holds, other regulatory objections to commencing or continuing a clinical trial or the

inability to obtain regulatory approval to commence a clinical trial in countries that require  such
approvals;

(cid:129) failure to reach agreement with the FDA, CFDA, EMA or other regulators regarding the scope

or design of our clinical trials;

(cid:129) delay or failure in obtaining authorization to commence a trial or inability to comply  with

conditions imposed by a regulatory authority  regarding the scope or design of a clinical trial;

(cid:129) our inability to enroll a sufficient number of patients who  meet  the inclusion and  exclusion

criteria in a clinical trial;

89

(cid:129) our inability to conduct a clinical trial in accordance  with regulatory requirements or our clinical

trial protocols;

(cid:129) clinical sites and investigators deviating from a  trial protocol, failing  to  conduct the  trial in

accordance with regulatory requirements, or dropping out of a trial;

(cid:129) withdrawal of clinical trial sites from our  clinical trials  as a  result  of changing  standards of care

or the ineligibility of a site to participate in  our  clinical trials;

(cid:129) inability to identify and maintain a sufficient number of trial sites,  many of which may already be
engaged in other clinical trial programs, including  some that may be for the  same indication;

(cid:129) failure of our third-party clinical research  organizations to satisfy their contractual duties  or

meet expected deadlines;

(cid:129) delay or failure in adding new clinical trial sites;

(cid:129) ambiguous or negative interim results, or results  that are inconsistent  with earlier results;

(cid:129) unfavorable or inconclusive results of clinical trials and supportive nonclinical studies, including

unfavorable results regarding effectiveness of drug candidates during clinical  trials;

(cid:129) feedback from the FDA, CFDA, EMA, an  IRB, data  safety monitoring boards, or comparable
entities, or results from earlier stage or concurrent  preclinical studies and clinical trials, that
might require modification to the protocol;

(cid:129) unacceptable risk-benefit profile or  unforeseen  safety issues or adverse side  effects;

(cid:129) decision by the FDA, CFDA, EMA,  an IRB, comparable entities, or us, or  recommendation by a
data safety monitoring board or comparable  regulatory entity,  to  suspend or terminate clinical
trials at any time for safety issues or for any other reason;

(cid:129) failure to demonstrate a benefit from using a  drug or biologic;

(cid:129) lack of adequate funding to continue the  clinical trial due  to  unforeseen  costs or other  business

decisions;

(cid:129) our inability to reach agreements on  acceptable  terms with  prospective  contract  research
organizations, or CROs, and trial sites, the terms of which can be subject  to  extensive
negotiation and may vary significantly among different CROs and  trial sites;

(cid:129) our inability to obtain approval from  IRBs  or ethics  committees to conduct clinical trials at  their

respective sites;

(cid:129) manufacturing issues, including problems  with manufacturing or timely  obtaining  from third

parties sufficient quantities of a drug candidate  for use in  a  clinical trial; and

(cid:129) difficulty in maintaining contact with  patients after treatment,  resulting in  incomplete data.

Changes in regulatory requirements and guidance may also occur, and we may need to amend

clinical trial protocols submitted to applicable regulatory authorities to reflect these changes.
Amendments may  require us to resubmit  clinical trial protocols to IRBs or ethics committees  for
re-examination, which may impact the  costs, timing or successful completion of a clinical trial.

If we  experience delays in the completion of, or  the termination of, a clinical trial, of any of our
drug candidates, the commercial prospects of  our drug  candidates will be harmed, and our ability to
generate product sales revenues from  any of those drug  candidates will be delayed.  In  addition, any
delays in completing our clinical trials will  increase  our  costs, slow  down our drug candidate
development and approval process, and  jeopardize our ability to commence product sales and generate
revenues. Any of these occurrences may  harm our business, financial condition and prospects

90

significantly. In addition, many of the  factors that cause,  or lead to, a delay in the  commencement or
completion of clinical trials may also  ultimately lead  to  the denial of regulatory approval of our drug
candidates.

If we  are required to conduct additional  clinical trials  or other studies  with respect  to  any of  our
drug candidates beyond those that we  initially  contemplated,  if we are  unable to successfully complete
our  clinical trials or other studies or  if the results  of these  studies are  not  positive or  are only modestly
positive, we may be delayed in obtaining  regulatory approval for that drug candidate,  we may  not  be
able to obtain regulatory approval at  all or we may  obtain  approval for indications that are not as
broad as intended. Our drug development  costs will also  increase if we experience  delays in testing  or
approvals, and we may not have sufficient funding to complete the testing and approval process.
Significant clinical trial delays could  allow our competitors to bring  drugs to market before  we do and
impair our ability to commercialize our drugs, if and when  approved. If any of  this occurs, our business
will be materially harmed.

Failure to successfully validate, develop  and obtain  regulatory approval  for companion diagnostics could harm
our drug development strategy.

As one of the key elements of our clinical development strategy,  we  seek to identify patient subsets
within a disease category who may derive  selective and meaningful benefit from the  drug  candidates we
are developing. In collaboration with partners, we plan to develop companion diagnostics to help  us  to
more accurately identify patients within  a  particular subset, both  during  our  clinical trials  and in
connection with the commercialization  of  our  drug candidates. Companion  diagnostics  are subject to
regulation by the FDA, CFDA, EMA  and other comparable regulatory authorities and  require separate
regulatory approval or clearance prior to commercialization. We do not develop companion diagnostics
internally, and thus we are dependent  on the  sustained cooperation and effort of our third-party
collaborators in developing and obtaining approval or clearance for these companion diagnostics. We
and our collaborators may encounter  difficulties in developing and obtaining approval  or clearance of
the companion diagnostics, including  issues relating to selectivity/specificity,  analytical  validation,
reproducibility or clinical validation.  Any delay or  failure by our collaborators to develop or obtain
regulatory approval or clearance of the  companion diagnostics could delay  or prevent approval  of  our
drug candidates. In addition, our collaborators may encounter  production  difficulties that could
constrain the supply of the companion  diagnostics, and  both they and  we may have  difficulties gaining
acceptance of the use of the companion  diagnostics in the clinical  community. A  failure of such
companion diagnostics to gain market acceptance would  have an adverse effect  on our ability to derive
revenues from sales of our drugs. In  addition,  the diagnostic company with  whom we contract  may
decide to discontinue selling or manufacturing the  diagnostic we anticipate  using  in connection  with
development and commercialization of our drug candidates or our relationship  with such  diagnostic
company may otherwise terminate. We  may  not  be  able  to enter into arrangements  with another
diagnostic company to obtain supplies of  an alternative diagnostic test for use in connection with the
development and commercialization of our drug candidates or do so  on  commercially reasonable terms,
which  could adversely affect and/or delay the  development or commercialization of  our drug
candidates.

Our drug candidates may cause undesirable adverse  events or  have other properties  that could  delay or
prevent their regulatory approval, limit  the commercial  profile  of an approved label, or result in significant
negative consequences following any regulatory approval.

Undesirable AEs caused by our drug candidates could cause us or regulatory authorities to
interrupt, delay or halt clinical trials and  could result in a more  restrictive label or  the delay  or denial
of regulatory approval by the FDA, CFDA, EMA or  other comparable regulatory  authority.  Results of
our  trials  could reveal a high and unacceptable severity or prevalence  of  AEs. In such an event, our

91

trials could be suspended or terminated and the FDA, CFDA, EMA or  other  comparable  regulatory
authorities could order us to cease further  development of, or deny approval  of,  our  drug  candidates
for any or all targeted indications. Undesirable AEs  caused by BGB-3111  may include, but  are not
limited to, neutropenia, petechiae (spots  that appear on the skin as  a  result of bleeding), purpura
(subcutaneous bleeding), bruising, rash,  peripheral neuropathy,  and fatigue. Undesirable AEs caused by
BGB-290 may include, but are not limited to, nausea, vomiting, diarrhea, lethargy, neutropenia,
anemia, thrombocytopena, hypophosphataemia,  and  hot  flush. Undesirable AEs caused by BGB-283
may include, but are not limited to, thrombocytopenia, fatigue,  rash, hand-foot syndrome, hypertension,
and anorexia. Drug-related AEs could  affect patient recruitment or the ability of enrolled  subjects to
complete the trial, and could result in potential product  liability  claims. Any  of these  occurrences may
harm our reputation, business, financial condition and prospects significantly.

Additionally if one or more of our drug candidates  receives regulatory  approval, and we  or others
later identify  undesirable side effects caused by such  drugs,  a number of potentially  significant negative
consequences could result, including:

(cid:129) we may suspend marketing of the drug;

(cid:129) regulatory authorities may withdraw approvals  or revoke  licenses of the drug;

(cid:129) regulatory authorities may require  additional warnings  on the label;

(cid:129) we may be required to develop a REMS  for the  drug or, if a  REMS is already in place, to
incorporate additional requirements under  the REMS, or to develop a similar  strategy as
required by a comparable regulatory  authority;

(cid:129) we may be required to conduct post-market studies;

(cid:129) we could be sued and held liable for harm caused to subjects  or patients;  and

(cid:129) our reputation may suffer.

Any of these events could prevent us  from achieving  or maintaining market acceptance of the
particular drug candidate, if approved,  and  could significantly harm our business, results  of  operations
and prospects.

Further, combination therapy, such as using  our  wholly-owned  drug candidates  as well as  third-
party agents, involves unique AEs that  could be exacerbated compared to  AEs from monotherapies.
These types of AEs could be caused by our  drug  candidates and could also cause us or  regulatory
authorities to interrupt, delay or halt clinical trials  and could result in a more  restrictive label  or the
delay or denial of regulatory approval by the FDA, CFDA, EMA  or other comparable regulatory
authority. Results of our trials could  reveal  a high and unacceptable severity or  prevalence of AEs.

A Fast Track Designation by the FDA, even if  granted for any of  our drug  candidates, may not  lead  to a
faster development or regulatory review or approval process, and does not  increase  the likelihood that our  drug
candidates will receive regulatory approval.

We  do not currently have Fast Track Designation for any of our drug candidates but may  seek  such

designation in the future. If a drug is  intended for the treatment of a serious or life-threatening
condition and the drug demonstrates  the potential  to  address unmet  medical needs for that condition,
the drug sponsor may apply for FDA Fast Track  Designation.  The FDA  has broad discretion whether
or not to grant this designation. Even if  we believe a particular drug candidate is  eligible for  this
designation, we cannot assure you that  the FDA would decide to grant  it. Even if  we do receive Fast
Track Designation, we may not experience a faster development process,  review or approval  compared
to conventional FDA procedures. The FDA may withdraw a  Fast  Track Designation if it  believes that

92

the designation is no longer supported  by data from our clinical development program. Many drugs
that have received Fast Track Designation have failed to obtain approval from  the FDA.

A Breakthrough Therapy Designation by the  FDA, even if granted for any  of our  drug  candidates, may not
lead to a faster development or regulatory review  or approval process, and  does not increase the likelihood that
our drug candidates will receive regulatory approval.

We  do not currently have Breakthrough Therapy Designation for any of our  drug candidates but
may seek it in the future. A Breakthrough  Therapy is  defined as a drug that is intended,  alone  or in
combination with one or more other drugs, to treat a serious or life-threatening  disease  or condition,
and preliminary clinical evidence indicates that the drug may demonstrate  substantial improvement over
existing therapies on one or more clinically  significant endpoints,  such as  substantial treatment effects
observed  early in clinical development. For drugs that  have been  designated as Breakthrough
Therapies, interaction and communication  between the FDA and the sponsor can help to identify the
most efficient path for development.

Designation as a Breakthrough Therapy is within the discretion of  the  FDA. Accordingly, even  if
we believe, after completing early clinical  trials,  that one of our drug candidates  meets the criteria for
designation as a Breakthrough Therapy,  the FDA  may  disagree and instead  decide not to grant  that
designation. In any event, the receipt  of a  Breakthrough Therapy designation for a drug candidate may
not result in a faster development process, review or approval  compared to drugs considered for
approval under conventional FDA procedures  and  does not assure ultimate approval by the  FDA. In
addition, even if one or more of our drug  candidates qualify as Breakthrough Therapies, the FDA may
later decide that such drug candidates  no  longer meet  the conditions for qualification.

We may  seek orphan drug exclusivity for some of our drug candidates, and  we may be unsuccessful.

Regulatory authorities in some jurisdictions, including the United States  and Europe, may

designate drugs for relatively small patient  populations as orphan drugs. Under  the Orphan Drug Act,
the FDA may designate a drug as an orphan  drug if  it  is a drug  intended to treat a rare disease or
condition, which is generally defined as a disease  with a patient population of fewer than 200,000
individuals in the United States, or that affects  more than  200,000 individuals in  the United  States  and
for which there is no reasonable expectation that costs  of research and  development of the  product for
the indication can be recovered by sales  of the  product in  the United  States. BGB-3111 received
orphan drug designation from the FDA for  CLL, MCL and WM in 2016.

Generally, if a drug with an orphan drug designation subsequently receives the first regulatory

approval for the indication for which  it has  such designation, the drug  is entitled  to  a period  of
marketing exclusivity, which precludes the  FDA  or EMA,  from approving  another  marketing
application for the same drug for the  same indication  during  the period of exclusivity. The applicable
period is seven years in the United States and 10  years  in Europe.  The European exclusivity period can
be reduced to six years if a drug no longer meets the  criteria for  orphan drug designation or  if the  drug
is sufficiently profitable so that market  exclusivity is  no longer  justified. Orphan drug exclusivity  may  be
lost if the FDA or the EMA determines  that the request  for  designation was  materially defective or if
the manufacturer is unable to assure sufficient  quantity of the drug to meet the  needs  of  patients with
the rare disease or condition.

Even if we obtain orphan drug exclusivity for a drug candidate, that exclusivity may not effectively

protect the drug candidate from competition  because different drugs can be approved  for the  same
condition and the same drugs can be approved  for a different condition but  used  off-label for any
orphan indication we may obtain. Even  after an orphan drug is approved, the  FDA can  subsequently
approve a drug that is otherwise the  same drug for the same condition if the FDA concludes that the

93

later drug is clinically superior in that it is shown to be safer, more effective  or makes a major
contribution to patient care.

Even if we receive regulatory approval  for  our drug candidates, we will  be subject  to ongoing regulatory
obligations and continued regulatory review, which may result in significant additional expense and  we may be
subject to penalties if we fail to comply  with regulatory requirements or  experience unanticipated problems
with our  drug candidates.

If our drug candidates are approved,  they will be subject  to  ongoing regulatory requirements for

manufacturing, labeling, packaging, storage, advertising, promotion, sampling, record-keeping, conduct
of post-marketing studies, and submission  of safety,  efficacy, and  other post-market information,
including both federal and state requirements in the United States  and requirements of comparable
regulatory authorities.

Manufacturers and manufacturers’ facilities are required  to  comply with extensive FDA,  CFDA,
EMA and comparable regulatory authority,  requirements, including, in the  United States, ensuring  that
quality control and manufacturing procedures conform to cGMP regulations. As such,  we and our
contract manufacturers will be subject  to  continual review and  inspections to assess  compliance with
cGMP and adherence to commitments  made  in any NDA or  BLA,  other  marketing application, and
previous responses to inspection observations. Accordingly, we  and others with whom we work must
continue to expend time, money and effort in all areas of regulatory  compliance, including
manufacturing, production and quality control.

Any regulatory approvals that we receive for our drug candidates may be  subject to limitations  on

the approved indicated uses for which  the drug  may  be  marketed  or to the conditions  of  approval, or
contain requirements for potentially  costly  post-marketing  testing, including Phase 4 clinical trials and
surveillance to monitor the safety and  efficacy of the drug candidate.  The FDA may also  require a
REMS program as a condition of approval of our drug candidates,  which could entail requirements for
long-term patient follow-up, a medication  guide, physician communication plans  or additional elements
to ensure safe use, such as restricted  distribution methods,  patient  registries and  other  risk
minimization tools. In addition, if the  FDA, CFDA, EMA  or a  comparable regulatory authority
approves our drug candidates, we will have to comply  with requirements including,  for example,
submissions of safety and other post-marketing information and  reports, registration, as well as
continued compliance with cGMP and GCP,  for any clinical trials that we conduct post-approval.

The FDA may seek to impose a consent decree  or withdraw marketing approval  if  compliance with

regulatory requirements and standards  is  not  maintained or if  problems occur after  the drug reaches
the market. Later discovery of previously  unknown  problems with our  drug candidates, including AEs
of unanticipated severity or frequency, or with our third-party  manufacturers  or manufacturing
processes, or failure to comply with regulatory requirements, may result in revisions  to  the approved
labeling to add new safety information; imposition of post-market studies  or clinical  studies to assess
new safety risks; or imposition of distribution restrictions or other restrictions under a REMS program.
Other potential consequences include, among  other things:

(cid:129) restrictions on the marketing or manufacturing of our drugs, withdrawal of the  product from  the

market, or voluntary or mandatory product recalls;

(cid:129) fines, untitled or warning letters, or holds on  clinical trials;

(cid:129) refusal by the FDA to approve pending  applications or supplements to  approved applications

filed by us or suspension or revocation of license approvals;

(cid:129) product seizure or detention, or refusal  to  permit  the import  or  export of  our drug  candidates;

and

94

(cid:129) injunctions or the imposition of civil or  criminal penalties.

The FDA strictly regulates marketing,  labeling, advertising and promotion of products that are

placed on the market. Drugs may be  promoted only for their approved  indications and  for use in
accordance with the provisions of the approved  label. The  FDA, CFDA, EMA and  other  regulatory
authorities actively enforce the laws and regulations prohibiting  the promotion of off-label uses,  and a
company that is found to have improperly promoted off-label uses  may be  subject to significant  liability.
The policies of the FDA, CFDA, EMA and of other regulatory authorities may change and additional
government regulations may be enacted  that could prevent, limit  or  delay regulatory approval of our
drug candidates. We cannot predict the  likelihood, nature or extent  of government regulation that may
arise from future legislation or administrative  action, either  in the United  States or abroad.  If we  are
slow or unable to adapt to changes in existing requirements or the  adoption of new  requirements or
policies, or if we are not able to maintain regulatory  compliance, we may lose any regulatory  approval
that we may have obtained and we may  not  achieve or sustain  profitability.

In addition, if we were able to obtain  accelerated  approval of any of our  drug candidates,  the FDA
would require us to conduct a confirmatory study to verify the  predicted clinical  benefit and  additional
safety studies. Other comparable regulatory authorities outside the United  States, such as  the CFDA or
EMA, may have similar requirements. The results  from the confirmatory study may not support  the
clinical benefit, which would result in  the approval being withdrawn. While operating under accelerated
approval, we will be subject to certain  restrictions that we would not be subject  to  upon receiving
regular approval.

Risks Related to Commercialization  of Our  Drug Candidates

If we are not able to obtain, or experience  delays in obtaining,  required regulatory approvals,  we will  not  be
able to commercialize our drug candidates, and our ability to generate revenue will  be materially impaired.

We  currently do not have any drug candidates that have gained regulatory  approval for  sale in the
United States, European Union, China or any  other country, and we  cannot guarantee that we will ever
have marketable drugs. Our business  is  substantially  dependent on our ability to complete the
development of, obtain regulatory approval for and successfully commercialize drug candidates in a
timely manner. We cannot commercialize drug  candidates without first  obtaining regulatory approval to
market each drug from the FDA, CFDA,  EMA  and  comparable regulatory authorities. BGB-3111,
BGB-A317, BGB-290 and BGB-283 are each  currently  undergoing clinical trials. We  cannot predict
whether these trials and future trials will  be  successful or  whether  regulators will agree with  our
conclusions regarding the preclinical  studies  and  clinical trials  we  have conducted  to  date.

Before obtaining regulatory approvals for  the commercial sale of any drug candidate for a target

indication, we must demonstrate in preclinical studies and well-controlled clinical  trials, and,  with
respect to approval in the United States, to the satisfaction of the FDA,  that  the drug candidate is safe
and effective  for use for that target indication and that the manufacturing facilities, processes and
controls are adequate. In the United  States, we  have not submitted an  NDA or  BLA for  any of our
drug candidates. An NDA or BLA must  include  extensive  preclinical and clinical  data  and supporting
information to establish, in the case of an NDA,  the drug candidate’s  safety and  effectiveness or,  in the
case of a BLA, safety, purity and potency  for each  desired  indication. The NDA or BLA  must  also
include significant information regarding  the chemistry,  manufacturing  and controls  for the  drug.
Obtaining approval of an NDA or BLA  is a lengthy, expensive and  uncertain  process,  and approval
may not be obtained. If we submit an NDA or BLA  to  the FDA, the FDA decides whether to accept
or reject the submission for filing. We cannot  be  certain that any submissions will be accepted for filing
and review by the FDA.

Regulatory authorities outside of the United States, such as the  EMA or regulatory authorities in
Australia and New Zealand and in emerging markets, such  as in the  PRC,  also have requirements for

95

approval of drugs for commercial sale with which  we must comply prior to marketing  in those  areas.
Regulatory requirements can vary widely  from  country  to  country and could  delay or prevent the
introduction of our drug candidates.  Clinical trials conducted in  one  country may not be accepted by
regulatory authorities in other countries,  and obtaining regulatory approval in one country does not
mean that regulatory approval will be obtained in any other country.  Approval processes  vary  among
countries and can involve additional product  testing and validation and  additional  administrative review
periods. Seeking non-U.S. regulatory approval could  require additional nonclinical studies or  clinical
trials, which could be costly and time  consuming. The non-U.S. regulatory approval process  may
include all of the risks associated with  obtaining FDA  approval. For  all of these  reasons,  we may not
obtain non-U.S. regulatory approvals on a timely basis, if at all.

Specifically, in China, the CFDA categorizes domestically-manufactured innovative  drug

applications as Category 1 and imported innovative  drug applications as Category 5. To  date, most of
local companies’ domestically-manufactured drug applications are filed  in Category 1 if the drug has
not already been approved by the FDA or EMA.  Most multinational pharmaceutical  companies’ drug
registration applications are filed in Category  5 applicable to imported drugs,  formerly known as
Category 3 prior to the reclassification  implemented by the CFDA in 2016. These  two categories have
distinct approval pathways, as described in ‘‘Item 1—Business—Regulatory Framework and  Structural
Advantages of Being a China-Based Research and Development Organization.’’ We  believe the local
drug registration pathway, Category 1,  is a faster and  more efficient path to approval in the Chinese
market than Category 5. Companies  are  required to obtain  Clinical Trial  Application  approval before
conducting clinical trials in China. This  registration pathway has  a  fast track  review and  approval
mechanism if the drug candidate is on  a  national priority list. The imported  drug  registration pathway,
Category 5, is more complex and is evolving.  China  Category  5 registration applications may  only  be
submitted after a drug has obtained an  NDA approval  and received the  CPP granted by a  major drug
regulatory authority, such as the FDA  or  EMA.

Further, in August 2015, the Chinese  State Council issued a statement, Opinions on reforming the

review and approval process for pharmaceutical  products and medical devices that contained several
potential policy changes that could benefit the  pharmaceutical industry:

(cid:129) A plan to accelerate innovative drug  approval with a special  review and approval process, with  a
focus on areas of high unmet medical needs, including  drugs  for HIV, cancer, serious infectious
diseases  and orphan diseases, drugs on national  priority lists.

(cid:129) A plan to adopt a policy which would  allow companies to act as  the marketing authorization

holder and to hire contract manufacturing organizations  to produce drug products.

(cid:129) A plan to improve the review and  approval of clinical trials, and to allow companies  to  conduct
clinical trials at the same time as they are being conducted in  other countries and encourage
local clinical trial organizations to participate in  international multi-center clinical  trials.

In November 2015, the CFDA released  the Circular Concerning Several Policies on Drug Registration

Review and Approval, which further clarified the following policies potentially  simplifying and
accelerating the approval process of clinical trials:

(cid:129) A one-time umbrella approval procedure allowing approval  of all phases of a  new drug’s  clinical
trials at once, rather than the current phase-by-phase  approval procedure, will be adopted for
new drugs’ clinical trial applications.

(cid:129) A fast track drug registration or clinical trial approval pathway will be available for the following

applications: (1) registration of innovative new drugs treating HIV, cancer, serious infectious
diseases and orphan diseases; (2) registration of pediatric drugs; (3) registration of  geriatric
drugs and drugs treating China-prevalent diseases in elders;  (4) registration  of drugs sponsored
by national science and technology grants; (5) registration of innovative drugs using advanced

96

technology, using innovative treatment methods, or having distinctive clinical benefits;
(6) registration of foreign innovative drugs to be manufactured locally in China; and
(7) concurrent applications for new drug clinical trials  which are  already  approved  in the United
States or European Union or concurrent drug registration  applications for drugs  which have
applied for marketing authorization and  passed  onsite inspections in the United States or
European Union and are manufactured using the same  production  line in  China; and  (8) clinical
trial applications for drugs with urgent clinical need and patent  expiry within three years, and
marketing authorization applications for drugs with urgent clinical need and patent expiry  within
one year.

In February 2016, the CFDA released  the Opinions on Priority Review and Approval  for Resolving

Drug Registration Applications Backlog, which further clarified the following policies  potentially
accelerating the approval process of certain  clinical trials  or drug registrations:

(cid:129) A fast  track drug registration or clinical trial approval pathway will be available for the following

drug registration applications with distinctive  clinical benefits: (1)  registration  application  of
innovative drugs not sold within or outside China; (2) registration application of  innovative drugs
transferred to be manufactured in China; (3) registration application of drugs using  advanced
technology, using innovative treatment methods, or having distinctive treatment advantages;
(4) clinical trial applications for drugs with patent expiry within three years,  and marketing
authorization applications for drugs with patent expiry  within one year;  (5) concurrent
applications for new drug clinical trials which are  already  approved  in the United  States or
European Union, or concurrent drug registration applications for drugs which  have applied for
marketing authorization and passed onsite inspections  in the United States or European Union
and are manufactured using the same production line in China;  (6) traditional  Chinese
medicines (including ethnic medicines) with clear clinical position in prevention and  treatment of
serious diseases; and (7) registration application of new drugs  sponsored by  national key
technology projects or national key development  projects.

(cid:129) A fast  track drug registration approval pathway will be available for drug registration

applications with distinctive clinical  benefits for  prevention and treatment of HIV, phthisis, viral
hepatitis, orphan diseases, cancer, malignant neoplasms,  children’s diseases, and geriatrics.

(cid:129) In  March 2016, the CFDA released a circular, CFDA  Announcement on Reforms of

Pharmaceutical Registration Classification, which outlined the re-classifications of  drug
applications. Under the new categorization, innovative drugs that have  not  been marketed either
within or outside China remain Category 1, while drugs marketed outside China  seeking
marketing approval in China are now Category 5.

(cid:129) However, because these laws and regulations in relation to such above-mentioned fast  track

clinical trial approval and drug registration pathway  were newly issued, uncertainty remains with
respect to their implementation. We expect  that the CFDA review and approval process will
improve over time. However, how and when this approval process  will be changed is still  subject
to further policies to be issued by the  CFDA and is currently uncertain.

(cid:129) The process to develop, obtain regulatory approval for and commercialize drug candidates  is

long, complex and costly both inside  and  outside the United States and  China,  and approval  is
never guaranteed. Even if our drug  candidates  were to successfully obtain approval  from the
regulatory authorities, any approval might significantly limit the approved indications for  use, or
require that precautions, contraindications or warnings be  included on  the product  labeling, or
require expensive and time-consuming post-approval clinical studies  or surveillance as  conditions
of approval. Following any approval for commercial sale of our drug candidates, certain changes
to the  drug, such as changes in manufacturing  processes and additional  labeling claims, may be
subject to additional review and approval by the FDA, CFDA and  EMA and comparable

regulatory authorities. Also, regulatory approval for any of our drug candidates may be
withdrawn. If we are unable to obtain regulatory approval for our drug candidates in one or
more jurisdictions, or any approval contains significant limitations, our  target market  will  be
reduced and our ability to realize the full market potential of our drug  candidates will be
harmed. Furthermore, we may not be able to obtain sufficient  funding or generate sufficient
revenue and cash flows to continue  the development of any other drug  candidate in the future.

A Category 1 designation by the CFDA  may be revoked or may not be granted for any  of  our drug candidates
or may not lead to faster development or regulatory review or  approval  process  and does not increase the
likelihood that our drug candidates will receive  regulatory  approval.

We  believe the local drug registration  pathway, Category 1, is  a faster  and  more efficient path to

approval in the Chinese market than the  drug registration pathway  for imported drugs under
Category 5. Companies are required  to  obtain Clinical  Trial Application approval before conducting
clinical trials in China. This registration  pathway has a fast track  review and approval mechanism  if  the
drug candidate is on a national priority  list. Imported drug  candidates under Category 5 cannot qualify
for the national priority list to benefit  from fast  track reviews. Our  drug candidates are all new
therapeutic agents  and we have built  both research and development,  clinical trial capacities, and
commercial manufacturing facilities in  China. As  a result, we expect all of our current drug candidates
to fall within the Category 1 application  process, but cannot be sure we will be granted or  be  able to
maintain Category 1 designation.

Even if any of our drug candidates receives  regulatory approval, they may  fail  to achieve the  degree of market
acceptance by physicians, patients, third-party  payors and others in the medical  community necessary  for
commercial success.

If any of our drug candidates receives regulatory approval, it may nonetheless fail  to  gain sufficient
market acceptance by physicians, patients, third-party payors  and others in the medical community.  For
example, current cancer treatments like  chemotherapy and  radiation therapy are well  established in the
medical community, and doctors may continue to rely on these treatments to the  exclusion of our drug
candidates, such as BGB-A317, BGB-3111, BGB-290 and BGB-283.  In addition, physicians, patients
and third-party payors may prefer other novel products to ours. If our drug candidates  do  not  achieve
an adequate level of acceptance, we may not generate significant product  sales revenues and we  may
not become profitable. The degree of  market  acceptance of our drug candidates, if  approved for
commercial sale, will depend on a number of factors,  including:

(cid:129) the clinical indications for which our drug candidates  are approved;

(cid:129) physicians, hospitals, cancer treatment  centers  and patients considering our drug candidates as a

safe and effective treatment;

(cid:129) the potential and perceived advantages of our drug  candidates over alternative treatments;

(cid:129) the prevalence and severity of any  side effects;

(cid:129) product labeling or product insert  requirements  of  the FDA, CFDA, EMA  or other comparable

regulatory authorities;

(cid:129) limitations or warnings contained in the  labeling approved by  the FDA, CFDA, EMA or  other

comparable regulatory authorities;

(cid:129) the timing of market introduction  of our drug  candidates as well as competitive drugs;

(cid:129) the cost of treatment in relation to  alternative treatments;

98

(cid:129) the amount of upfront costs or training required  for physicians to administer our drug

candidates;

(cid:129) the availability of adequate coverage, reimbursement and pricing by third-party  payors and

government authorities;

(cid:129) the willingness of patients to pay out-of-pocket in the absence of  coverage and reimbursement

by third-party payors and government authorities;

(cid:129) relative convenience and ease of administration, including as compared to alternative  treatments

and competitive therapies; and

(cid:129) the effectiveness of our sales and marketing  efforts.

If our drug candidates are approved  but fail to achieve market acceptance among physicians,
patients, hospitals, cancer treatment centers or others in the medical community, we will not be able  to
generate significant revenue. Even if our drugs  achieve market  acceptance, we  may not be able  to
maintain that market acceptance over time if new products or  technologies are  introduced  that  are
more favorably received than our drugs, are more cost  effective or render our drugs obsolete.

We currently have no marketing and sales  organization and have no experience in marketing  drugs. If we  are
unable to establish marketing and sales  capabilities or enter into agreements with third parties to market and
sell our drug candidates, we may not be  able to generate product  sales revenue.

We  currently have no sales, marketing or commercial product distribution capabilities and have no

experience in marketing drugs. We intend  to  develop an in-house  marketing organization  and sales
force, which will require significant capital expenditures, management resources  and time. We will have
to compete with other pharmaceutical and biotechnology companies to recruit, hire,  train and  retain
marketing and sales personnel.

If we  are unable or decide not to establish internal sales,  marketing  and commercial distribution

capabilities for any or all drugs we develop, we will likely  pursue collaborative arrangements regarding
the sales and marketing of our drugs. However, there can be no  assurance that we will  be  able to
establish or maintain such collaborative arrangements,  or if we are able to do so,  that  they will have
effective sales forces. Any revenue we receive will depend upon the efforts of  such third parties, which
may not be successful. We may have  little or no control  over  the marketing and sales efforts of such
third parties, and our revenue from product sales may be lower  than  if we had commercialized our
drug candidates ourselves. We also face  competition in our search for third parties to assist us with the
sales and marketing efforts of our drug candidates.

There can be no assurance that we will be able to develop  in-house sales and  commercial
distribution capabilities or establish or maintain relationships  with third-party collaborators  to
successfully commercialize any product,  and as a  result, we may not be able  to  generate product sales
revenue.

99

We face substantial competition, which  may  result  in  others discovering, developing or commercializing
competing drugs before or more successfully than we do.

The development and commercialization of  new drugs is highly competitive. We face  competition

with respect to our current drug candidates,  and  will face competition  with respect  to  any drug
candidates that we may seek to develop  or  commercialize in the  future, from  major pharmaceutical
companies, specialty pharmaceutical  companies and biotechnology companies  worldwide. There are a
number of large pharmaceutical and  biotechnology companies that currently  market  and sell drugs or
are pursuing the development of drugs for  the treatment  of  cancer for which  we are  developing  our
drug candidates. Some of these competitive drugs and therapies  are based  on scientific approaches that
are the same as or similar to our approach, and others are based  on entirely different  approaches.
Potential competitors also include academic institutions, government agencies and other public and
private  research organizations that conduct research, seek patent protection and establish collaborative
arrangements for research, development, manufacturing and commercialization.

Specifically, there are a large number of companies developing  or  marketing treatments  for cancer,

including many major pharmaceutical  and  biotechnology companies. See ‘‘Item 1—Business—
Competition.’’

Our commercial opportunity could be reduced  or eliminated  if our competitors  develop  and

commercialize drugs that are safer, more effective, have fewer or  less severe  side effects, are  more
convenient or are less expensive than  any  drugs that we may develop. Our  competitors also may  obtain
approval from the FDA, CFDA, EMA  or  other  comparable  regulatory authorities  for their drugs more
rapidly than we may obtain approval for  ours,  which could result in our competitors establishing a
strong market position before we are able to enter the market and or slow our regulatory approval.
Furthermore, the regulatory framework in China regarding imported drugs may undergo changes that
could erode our competitive advantage  with respect to the  Chinese domestic regulatory pathway. For
example, on March 17, 2017, the CFDA published a draft  Decision on Regulation Adjustment on
Imported Drugs Registration that if adopted  would potentially  accelerate the regulatory approval
process for imported drugs.

Many of the companies against which  we are competing  or against which we may compete  in the

future have significantly greater financial resources and  expertise in  research  and development,
manufacturing, preclinical testing, conducting  clinical trials,  obtaining regulatory approvals and
marketing approved drugs than we do. Mergers  and  acquisitions in the pharmaceutical and
biotechnology industries may result in even more resources being concentrated among a  smaller
number of our competitors. Smaller  and  other  early-stage companies may also prove to be significant
competitors, particularly through collaborative arrangements with large and established  companies.
These third parties compete with us in  recruiting  and  retaining qualified  scientific and management
personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in
acquiring technologies complementary to, or necessary for, our programs.

Our drug candidates for which we intend  to  seek approval as biological  or drug  products may  face
competition sooner than expected.

With the enactment of the Biologics  Price Competition and Innovation Act  of  2009, or BPCIA, as

part of the ACA, as amended by the  Health Care and Education Reconciliation Act of 2010,  or,
collectively the ACA, an abbreviated  pathway for  the approval  of biosimilar and interchangeable
biological products was created in the United States. The abbreviated regulatory pathway  establishes
legal authority for the FDA to review and approve biosimilars, including the  possible  designation  of  a
biosimilar as ‘‘interchangeable,’’ based  on their similarity to existing  reference product. Under  the
BPCIA, an application for a biosimilar  product  cannot be approved  by the FDA  until 12 years after the
reference product was approved under  a  BLA. The BPCIA is complex and is only beginning to be

100

interpreted and implemented by the FDA. As a result, its ultimate impact,  implementation and
meaning are subject to uncertainty, and  it  could have a material adverse effect on  the future
commercial prospects for our biological products, including BGB-A317, if  approved.

We  believe that any of our drugs approved as a biological product  under a BLA  should qualify for

the 12-year period of exclusivity. However:

(cid:129) a potential competitor could seek and obtain approval  of  its  own BLA during  our  exclusivity

period instead of seeking approval of a biosimilar version; and

(cid:129) the FDA could consider a combination  therapy which contains  both  drug  and biological product
components, to be a drug subject to  review pursuant to an  NDA, and therefore eligible for a
significantly shorter marketing exclusivity period as provided  under the  Drug Price Competition
and Patent Term Restoration Act of 1984.

Moreover, the extent to which a biosimilar, once approved, will  be  substituted for  any one  of  our

reference products in a way that is similar  to traditional  generic substitution for non-biological products
is not yet clear and will depend on a number  of marketplace and regulatory  factors that are still
developing.

In addition, a drug product approved  under  an NDA, such as BGB-3111, BGB-290 or  BGB-283, if

they were to be approved, could face  generic competition earlier than expected.  The  enactment  of  the
Generic Drug User Fee Amendments  of  2012 as part of the  Food and Drug  Administration  Safety and
Innovation Act of 2012 established a  user fee program that will generate hundreds of millions of  dollars
in funding for the FDA’s generic drug  review program. Funding from the user fee program, along with
performance goals that the FDA negotiated  with the generic  drug industry, could significantly decrease
the timeframe for FDA review and approval of generic drug applications.

The market opportunities for our drug candidates may  be limited  to those patients who are ineligible for  or
have failed prior treatments and may be small.

Cancer therapies are sometimes characterized as  first line, second line or  third line, and the FDA

often approves new therapies initially only for third line use. When  cancer is detected early enough,
first line therapy is sometimes adequate to cure the cancer or prolong life without a cure.  Whenever
first line therapy, usually chemotherapy, hormone therapy,  surgery or  a  combination of these, proves
unsuccessful, second line therapy may  be  administered. Second line therapies often consist of more
chemotherapy, radiation, antibody drugs,  tumor targeted small  molecules  or a combination of these.
Third line therapies can include bone  marrow transplantation, antibody and small  molecule targeted
therapies, more invasive forms of surgery and  new  technologies. In markets with  approved therapies,
we expect to initially seek approval of  our drug  candidates as  a  later stage therapy  for patients who
have failed other approved treatments. Subsequently, for those drugs  that prove  to  be  sufficiently
beneficial, if any, we would expect to  seek approval as a  second line therapy and potentially  as a first
line therapy, but there is no guarantee  that our drug candidates, even if  approved,  would be approved
for second line or first line therapy. In addition, we may have to conduct additional clinical  trials prior
to gaining approval for second line or  first  line therapy.

Our projections of both the number  of people who have the  cancers we are targeting, as  well as
the subset of people with these cancers in a position to receive later stage therapy and who have  the
potential to benefit from treatment with our  drug candidates, are based on our beliefs and  estimates.
These estimates have been derived from  a variety of sources, including scientific literature, surveys  of
clinics, patient foundations or market  research and may prove to be incorrect.  Further, new studies may
change the estimated incidence or prevalence of these cancers. The number of patients may  turn  out to
be lower than expected. Additionally, the  potentially addressable patient population  for our drug
candidates may be limited or may not be amenable to treatment with our  drug candidates. Even  if  we

101

obtain significant market share for our drug candidates,  because the potential target populations are
small, we may never achieve profitability without obtaining regulatory approval for additional
indications, including use as a first or  second line therapy.

Our market opportunities may also be  limited  by competitor treatments that may enter the market.

See ‘‘—We face substantial competition,  which may  result in others  discovering, developing or
commercializing competing drugs before  or more successfully  than  we  do.’’

Even if we are able to commercialize any  drug candidates, the drugs may become subject to unfavorable
pricing  regulations, third party reimbursement practices or  healthcare reform initiatives, which could  harm
our business.

The regulations that govern regulatory approvals, pricing and  reimbursement for new  therapeutic
products vary widely from country to  country. Some countries  require  approval of the  sale price  of a
drug before it can be marketed. In many  countries,  the pricing  review period begins after marketing or
licensing approval is granted. In some  non-U.S.  markets,  prescription pharmaceutical  pricing remains
subject to continuing governmental control even after initial  approval  is granted. As  a result, we might
obtain regulatory approval for a drug  in a  particular country, but  then be subject to price  regulations
that delay our commercial launch of the  drug and negatively impact  the revenues  we are  able to
generate from the sale of the drug in that  country. Adverse pricing limitations may hinder our ability to
recoup our investment in one or more drug  candidates, even if  our drug candidates obtain regulatory
approval. For example, according to a statement, Opinions on reforming the review and  approval process
for pharmaceutical products and medical  devices, issued by the Chinese State Council in August  2015,
the enterprises applying for new drug approval will be required  to  undertake  that  the selling  price of
new drug on PRC mainland market shall  not  be  higher than the comparable market prices of  the
product  in its country of origin or PRC’s neighboring markets,  as applicable.

Our ability to commercialize any drugs successfully also will depend in part on  the extent to which

reimbursement for these drugs and related treatments will be available from government health
administration authorities, private health  insurers  and  other organizations. Government authorities and
third-party payors, such as private health  insurers and health maintenance  organizations, decide which
medications they will pay for and establish reimbursement  levels. A primary trend in  the global
healthcare industry is cost containment. Government authorities and  these third-party payors  have
attempted to control costs by limiting coverage  and the  amount  of reimbursement for particular
medications. Increasingly, third-party  payors are requiring that companies  provide them  with
predetermined discounts from list prices  and  are challenging the prices charged for medical products.
We  cannot be sure that reimbursement  will be available for any drug  that we  commercialize and, if
reimbursement is available, what the level of reimbursement will be. Reimbursement may impact the
demand for, or the price of, any drug  for which we obtain regulatory  approval. Obtaining
reimbursement for our drugs may be  particularly difficult because of  the higher prices often associated
with drugs administered under the supervision of a physician. If reimbursement is not available or  is
available only to limited levels, we may  not be able to successfully commercialize any drug candidate
that we successfully develop.

There may be significant delays in obtaining reimbursement for approved product  drugs, and
coverage may be more limited than the purposes  for which the drug  is approved  by  the FDA or other
comparable regulatory authorities outside  the United States. Moreover, eligibility for reimbursement
does not imply that any drug will be paid  for in all cases  or at  a rate  that covers our  costs, including
research, development, manufacture, sale and distribution. Interim payments  for new drugs, if
applicable, may also not be sufficient  to  cover our costs and may not be made  permanent. Payment
rates may vary according to the use of the  drug  and  the clinical setting in  which it is used,  may be
based on payments allowed for lower  cost drugs that are already reimbursed,  and may  be  incorporated
into existing payments for other services. Net  prices for drugs may be reduced by mandatory discounts

102

or rebates required by government healthcare  programs or private payors and  by  any future weakening
of laws that presently restrict imports of  drugs  from countries where they may be sold at lower prices
than in the United States. Third-party payors often rely upon Medicare coverage policy and  payment
limitations in setting their own reimbursement policies. Our inability to promptly  obtain  coverage  and
profitable payment rates from both government-funded and private payors  for new drugs that we
develop could have a material adverse  effect on our operating  results, our ability to raise  capital
needed to commercialize drugs and our  overall  financial condition.

Coverage and reimbursement may be limited or unavailable in certain market  segments for our drug
candidates, which could make it difficult for  us to  sell our drug candidates profitably.

Successful sales of our drug candidates, if approved,  depend on the availability  of adequate
coverage and reimbursement from third-party  payors. In addition,  because our drug candidates
represent new approaches to the treatment of  cancer,  we cannot accurately estimate the potential
revenue from our drug candidates.

Patients who are provided medical treatment for  their conditions  generally rely on  third-party

payors to reimburse all or part of the  costs associated with their  treatment. Adequate coverage and
reimbursement from governmental healthcare programs, such as Medicare and Medicaid in the  United
States, and commercial payors are critical to new drug acceptance.

Government authorities and third-party payors, such as private  health insurers and  health
maintenance organizations, decide which drugs and  treatments  they will cover  and the  amount  of
reimbursement. Coverage and reimbursement by a third-party payor may depend upon a number of
factors, including the third-party payor’s determination that use  of a drug is:

(cid:129) a covered benefit under its health plan;

(cid:129) safe, effective and medically necessary;

(cid:129) appropriate for the specific patient;

(cid:129) cost-effective; and

(cid:129) neither experimental nor investigational.

In the United States, no uniform policy of coverage and reimbursement for drugs exists among

third-party payors. As a result, obtaining coverage and  reimbursement approval of  a drug from a
government or other third-party payor  is  a time-consuming  and  costly process that could require us to
provide to each payor supporting scientific, clinical and cost-effectiveness  data  for the  use of our drugs
on a payor-by-payor basis, with no assurance that coverage and adequate  reimbursement will be
obtained. Even if we obtain coverage for a given  drug,  the resulting reimbursement payment rates
might not be adequate for us to achieve or sustain  profitability or may require co-payments that
patients find unacceptably high. Additionally, third-party payors may not cover, or provide adequate
reimbursement for, long-term follow-up evaluations required following the use of our genetically
modified drugs. Patients are unlikely to use our drug candidates unless coverage is provided and
reimbursement is adequate to cover a significant portion of  the  cost of our drug candidates. Because
our  drug candidates have a higher cost of  goods than conventional therapies, and  may require
long-term follow up evaluations, the risk that coverage and reimbursement rates may be inadequate for
us to achieve profitability may be greater.

The Chinese State Council asked central and  provincial authorities across the PRC to promote a

medical insurance program for major illnesses.  By the  end of 2015,  all urban and rural residents
covered by basic medical insurance programs  should be covered by  the insurance  program for major
illnesses, according to Chinese State Council policy number 2015-57, issued on July  28, 2015. As a
complement to basic insurance programs, this  program is  required to cover at least 50% of the  medical

103

cost as incurred by treating major illnesses, but falls  out of  the  coverage  of the basic insurance
programs. The Chinese State Council  requires provincial authorities to increase reimbursement  rates
over the next three years.

According to the PRC Central Government’s guidance issued in March 2015, each province will

decide which  drugs to include in its provincial major  illness  reimbursement lists and  the percentage of
reimbursement, based on local funding. For example, Zhejiang  province, located in the  Yangtze river
delta area with a population of 55 million, announced its provincial  major illness drug reimbursement
list in early 2015. The list includes 31 expensive  drugs,  among which 15 are targeted therapy agents for
cancer, including Glivec, Ireesa, Erbitux, Herceptin,  and  Rituxan. Although  it will take three years to
establish a comprehensive national coverage, the affordability  of the expensive, novel cancer agents to
Chinese patients will improve significantly  and  the targeted therapy market is  expected to enter  a fast
growing period.

We  intend to seek approval to market our drug  candidates in the  United  States, China, Europe
and in other selected jurisdictions. If we  obtain  approval in one  or  more non-U.S. jurisdictions for our
drug candidates, we will be subject to  rules and regulations in those jurisdictions. In some  non-U.S.
countries, particularly those in the European Union, the  pricing of drugs and  biologics is subject to
governmental control. In these countries, pricing negotiations with governmental  authorities  can take
considerable time after obtaining regulatory  approval of a  drug candidate. In addition, market
acceptance and sales of our drug candidates will depend  significantly on the  availability of adequate
coverage and reimbursement from third-party  payors for our drug  candidates and may be affected by
existing and future health care reform measures.

Recently enacted and future legislation may  increase the difficulty and cost for us to  obtain regulatory
approval of and commercialize our drug  candidates and affect the  prices  we may obtain.

In the United States, PRC, European  Union and some other  jurisdictions, there  have been a
number of legislative and regulatory changes and proposed  changes  regarding  the healthcare system
that could prevent or delay regulatory approval of our drug  candidates, restrict or regulate
post-approval activities and affect our ability to profitably sell any drug candidates for which we obtain
regulatory approval.

In the United States, the Medicare Prescription  Drug,  Improvement,  and  Modernization Act of

2003, or the MMA, changed the way Medicare  covers and pays  for pharmaceutical products. The
legislation expanded Medicare coverage for  drug purchases by  the elderly  and introduced  a new
reimbursement methodology based on average sales prices for physician-administered drugs. In
addition, this legislation provided authority for limiting the  number of drugs that will  be  covered in  any
therapeutic class. Cost reduction initiatives and  other provisions of this legislation could decrease the
coverage and price that we receive for  any approved  products. While the MMA only applies  to  drug
benefits for Medicare beneficiaries, private payors  often  follow  Medicare coverage policy and payment
limitations in setting their own reimbursement rates. Therefore, any reduction in reimbursement that
results from the MMA may result in a similar reduction in payments  from private payors.

More recently, in March 2010, then President Obama signed into  law  the ACA,  a sweeping  law
intended to broaden access to health  insurance, reduce  or constrain the growth of healthcare spending,
enhance remedies against fraud and abuse,  add  new transparency requirements for the healthcare and
health insurance industries, impose new taxes  and  fees  on the health  industry  and impose  additional
health policy reforms.

104

Among the provisions of the ACA of  importance  to  our  potential drug candidates are  the

following:

(cid:129) an annual, nondeductible fee on any entity that manufactures  or imports  specified branded

prescription drugs and biologics;

(cid:129) an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid

Drug Rebate Program;

(cid:129) expansion of healthcare fraud and abuse laws, including the False  Claims  Act and  the

Anti-Kickback Statute, new government investigative powers, and enhanced penalties  for
noncompliance;

(cid:129) a new  Medicare Part D coverage gap discount program, in which  manufacturers  must  agree  to

offer 50% point-of-sale discounts off negotiated prices;

(cid:129) extension of manufacturers’ Medicaid rebate liability;

(cid:129) expansion of eligibility criteria for Medicaid programs;

(cid:129) expansion of the entities eligible for discounts under  the Public Health Service  Act

pharmaceutical pricing program;

(cid:129) new requirements to report financial  arrangements with  physicians and teaching hospitals;

(cid:129) a new  requirement to annually report  drug  samples that manufacturers and  distributors  provide

to physicians; and

(cid:129) a new  Patient-Centered Outcomes Research Institute to  oversee, identify  priorities in, and
conduct comparative clinical effectiveness research, along  with funding for such research.

In addition, other legislative changes have been proposed and adopted in the United States since

the ACA was enacted. These changes included aggregate reductions  to  Medicare  payments to providers
of up to 2% per fiscal year, starting in 2013. In January 2013, then President  Obama signed into law
the American Taxpayer Relief Act of  2012,  which, among other  things, reduced Medicare payments to
several providers, and increased the statute  of limitations period for the government to recover
overpayments to providers from three  to  five years. These laws may result  in additional  reductions in
Medicare and other healthcare funding.

We  expect that the ACA, as well as other healthcare  reform measures  that may  be  adopted  in the
future, may result in more rigorous coverage criteria and in additional downward pressure on the price
that we receive for any approved drug.  Any reduction in reimbursement  from Medicare  or other
government programs may result in a  similar reduction in payments from private payors. The
implementation of cost containment measures or other healthcare reforms  may prevent us from  being
able to generate revenue, attain profitability, or  commercialize our drugs.

Legislative and regulatory proposals  have  been made to expand post-approval requirements  and

restrict sales and promotional activities for pharmaceutical products. We cannot be sure  whether
additional legislative changes will be enacted, or whether  FDA regulations, guidance or  interpretations
will be changed, or what the impact  of such changes on the regulatory approvals of our drug
candidates, if any, may be. In addition,  increased  scrutiny  by the  U.S.  Congress of the FDA’s approval
process may significantly delay or prevent  regulatory approval, as  well as subject us to more stringent
product  labeling and post-marketing testing and other requirements.

As a result of the 2016 election in the United  States,  the fate  of the ACA and other healthcare
laws is uncertain. The United States  House of Representatives  is considering approval of legislation to
repeal parts of the ACA, but it is uncertain whether Congress  will replace the  law  and what  any
replacement law would provide.

105

We may  be subject, directly or indirectly,  to  applicable U.S. federal and state anti-kickback, false claims laws,
physician payment transparency laws, fraud  and abuse  laws or  similar  healthcare and security laws  and
regulations, which could expose us to criminal sanctions,  civil penalties, contractual  damages, reputational
harm and diminished profits and future earnings.

Healthcare providers, physicians and  others play a  primary  role  in the recommendation and
prescription of any products for which  we  obtain regulatory  approval. If we obtain FDA approval for
any of our drug candidates and begin commercializing those  drugs  in the United States, our operations
may be subject to various federal and state fraud  and abuse laws, including, without  limitation, the
federal Anti-Kickback Statute, the federal False Claims Act, and physician payment sunshine laws and
regulations. These  laws may impact,  among other things, our proposed sales, marketing and education
programs. In addition, we may be subject to patient  privacy regulation by both the  federal government
and the states in which we conduct our  business. The laws that may affect our ability to operate
include:

(cid:129) the federal Anti-Kickback Statute,  which prohibits, among other things,  knowingly and  willfully
soliciting, receiving, offering or paying  any remuneration (including any kickback, bribe, or
rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce, or in  return  for,
either the referral of an individual, or the purchase, lease,  order or recommendation  of  any
good, facility, item or service for which  payment may be made, in whole or  in part,  under a
federal healthcare program, such as the Medicare and Medicaid programs;

(cid:129) federal civil and criminal false claims laws and civil monetary  penalty laws, such as the federal
False Claims Act, which impose criminal and civil penalties, including civil whistleblower or  qui
tam actions, against individuals or entities  for knowingly presenting, or  causing to be presented,
to the  federal government, claims for payment or approval from Medicare, Medicaid or other
third-party payors that are false or fraudulent  or making a false statement to avoid, decrease or
conceal an obligation to pay money to the  federal government;

(cid:129) the federal HIPAA, which created new federal  criminal statutes that prohibit knowingly  and
willfully executing, or attempting to execute, a scheme to defraud any healthcare  benefit
program or obtain, by means of false  or fraudulent pretenses,  representations, or  promises,  any
of the money or property owned by, or under the custody or  control of, any  healthcare benefit
program, regardless of the payor (e.g.,  public  or private) and knowingly and willfully  falsifying,
concealing or covering up by any trick or device a  material fact or  making any materially false
statements in connection with the delivery of, or  payment for, healthcare  benefits, items or
services relating to healthcare matters;

(cid:129) HIPAA, as amended by the Health  Information Technology  for Economic and  Clinical  Health
Act of 2009, and their respective implementing regulations, which impose requirements on
certain covered healthcare providers, health plans, and healthcare clearinghouses  as well as their
respective business associates that perform services for them that involve the use, or disclosure
of, individually identifiable health information, relating to the privacy,  security and transmission
of individually identifiable health information without appropriate authorization;

(cid:129) the federal false statements statute prohibits knowingly  and willfully  falsifying, concealing or
covering up a material fact or making  any materially false statement in connection with the
delivery of or payment for healthcare  benefits, items or services;

(cid:129) the federal transparency requirements under the ACA,  including the  provision commonly

referred to as the Physician Payments Sunshine Act, which requires manufacturers of drugs,
devices, biologics and medical supplies for  which payment is available  under Medicare, Medicaid
or the Children’s Health Insurance Program to report annually to the U.S. Department of
Health and Human Services information related  to  payments or other transfers of value  made to

106

physicians and teaching hospitals, as well as ownership and  investment  interests  held by
physicians and their immediate family members; and

(cid:129) federal consumer protection and unfair  competition laws, which  broadly  regulate marketplace

activities and activities that potentially harm  consumers.

Additionally, we are subject to state and non-U.S.  equivalents of  each of  the healthcare  laws
described above, among others, some of  which  may be broader  in scope and may apply regardless of
the payor. Many U.S. states have adopted laws  similar to the federal Anti-Kickback Statute, some  of
which  apply to the referral of patients for  healthcare  services reimbursed by any source, not just
governmental payors, including private insurers. In addition,  some states have passed laws that require
pharmaceutical companies to comply with  the April 2003 Office of Inspector General  Compliance
Program Guidance for Pharmaceutical Manufacturers and/or  the Pharmaceutical Research and
Manufacturers of America’s Code on  Interactions with Healthcare  Professionals.  Several states also
impose other marketing restrictions or require pharmaceutical  companies to make  marketing  or price
disclosures to the state. There are ambiguities as  to  what is  required to comply  with these state
requirements and if we fail to comply  with an  applicable  state law requirement we could be subject to
penalties.

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe
harbors available, it is possible that some of  our  business activities  could be subject to challenge  under
one or more of such laws. In addition, recent  health care  reform legislation has strengthened  these
laws. For example, the ACA, among other things,  amends  the intent requirement of the federal
Anti-Kickback and criminal healthcare fraud statutes.  As a  result of such  amendment, a person or
entity no longer needs to have actual knowledge of  these statutes or  specific intent  to  violate them in
order to have committed a violation.  Moreover, the  ACA provides that the government  may assert that
a claim including items or services resulting  from a violation of the federal Anti-Kickback Statute
constitutes a false or fraudulent claim for  purposes of the  False Claims Act.

Violations of fraud and abuse laws may be punishable by criminal and/or civil sanctions, including

penalties, fines and/or exclusion or suspension from federal and  state healthcare programs such as
Medicare and Medicaid and debarment from  contracting  with the U.S. government. In  addition,  private
individuals have the ability to bring actions on behalf of the U.S. government under the federal False
Claims Act as well as under the false  claims  laws of several states.

Neither the U.S. government nor the  U.S. courts have provided definitive guidance  on the
application of fraud and abuse laws to our  business.  Law enforcement  authorities are increasingly
focused on enforcing these laws, and it  is possible that some of  our practices may be challenged under
these laws. Efforts to ensure that our business arrangements with third parties  will comply with
applicable healthcare laws and regulations  will involve substantial costs. It is possible that governmental
authorities will conclude that our business practices  may  not comply with  current or future statutes,
regulations or case law involving applicable fraud and  abuse  or  other  healthcare laws and regulations.  If
any such actions are instituted against  us,  and  we are  not  successful in  defending ourselves or asserting
our  rights, those actions could have a significant  impact  on our business, including  the imposition of
civil, criminal and administrative penalties, damages,  disgorgement, monetary fines, possible exclusion
from participation  in Medicare, Medicaid  and other  federal  healthcare programs, contractual damages,
reputational harm, diminished profits and future earnings,  and curtailment of our operations, any  of
which  could adversely affect our ability  to  operate our business and  our results of  operations. In
addition, the approval and commercialization  of  any  of  our drug candidates outside the United States
will also likely subject us to non-U.S. equivalents  of the healthcare laws  mentioned above, among other
non-U.S.  laws.

If any of the physicians or other providers  or entities with whom we expect to do business with  are

found to be not in compliance with applicable  laws,  they may be subject to criminal, civil  or

107

administrative sanctions, including exclusions from government funded healthcare programs, which  may
also adversely affect our business.

We may  explore the licensing of commercialization rights  or other  forms of collaboration worldwide, which will
expose us to additional risks of conducting  business in additional international markets.

Non-U.S. markets are an important component of  our growth strategy.  If we  fail to obtain licenses
or enter into collaboration arrangements  with third  parties in these markets, or  if these parties  are not
successful, our revenue-generating growth  potential will be adversely  affected. Moreover, international
business relationships subject us to additional risks that may materially  adversely affect our  ability to
attain or sustain profitable operations, including:

(cid:129) efforts to enter into collaboration or licensing arrangements with  third parties in connection  with
our  international sales, marketing and distribution efforts may  increase  our  expenses or  divert
our  management’s  attention from the acquisition or development  of  drug candidates;

(cid:129) changes in a specific country’s or region’s political and cultural  climate or economic  condition;

(cid:129) differing regulatory requirements for drug approvals  and marketing  internationally;

(cid:129) difficulty of effective enforcement of  contractual  provisions in local jurisdictions;

(cid:129) potentially reduced protection for  intellectual property rights;

(cid:129) potential third-party patent rights;

(cid:129) unexpected changes in tariffs, trade barriers  and regulatory requirements;

(cid:129) economic weakness, including inflation or political instability, particularly in non-U.S.  economies

and markets;

(cid:129) compliance with tax, employment, immigration and labor  laws for employees traveling abroad;

(cid:129) the effects of applicable non-U.S. tax  structures  and potentially  adverse  tax consequences;

(cid:129) currency fluctuations, which could result in  increased operating expenses  and reduced revenue,

and other obligations incidental to doing business in another  country;

(cid:129) workforce uncertainty and labor unrest, particularly  in non-U.S. countries where labor unrest  is

more common than in the United States;

(cid:129) the potential for so-called parallel  importing, which is what happens when a  local seller, faced

with high or higher local prices, opts to import goods from a non-U.S. market with low or lower
prices rather than buying them locally;

(cid:129) failure of our employees and contracted third parties to comply with Office of  Foreign Asset

Control  rules and regulations and the  Foreign Corrupt Practices Act;

(cid:129) production shortages resulting from  any  events affecting  raw  material supply or manufacturing

capabilities abroad; and

(cid:129) business interruptions resulting from geo-political actions, including war and  terrorism,  or
natural disasters, including earthquakes, volcanoes, typhoons, floods, hurricanes  and fires.

These and other risks may materially adversely affect our ability to attain or sustain revenue from

international markets.

108

Risks Related to Our Intellectual Property

A significant portion of our intellectual property portfolio currently comprises pending  patent  applications  that
have not yet been issued as granted patents  and if our pending patent applications fail to  issue our business
will be adversely affected. If we are unable  to  obtain and maintain  patent protection for our technology and
drugs, our competitors could develop and  commercialize  technology and drugs similar  or identical  to ours,
and our ability to successfully commercialize our technology and  drugs may be adversely affected.

Our success depends in large part on our  ability to obtain and maintain patent protection  in the

United States, the PRC and other countries with respect to our proprietary technology and drug
candidates. As of March 21, 2017, we own eight issued U.S. patents and  eight pending U.S.  patent
applications as well as corresponding  patents and patent applications internationally.  In addition, we
own 13 pending international patent  applications under the  PCT, which we plan  to  file nationally in the
United States and other jurisdictions.  With respect to any issued patents in the United States and
Europe, we may be entitled to obtain a  patent term  extension to extend the  patent  expiration date
provided we meet the applicable requirements for obtaining such patent term extensions. We have
sought to protect our proprietary position by filing patent applications in  the United States,  the PRC
and other countries related to novel  technologies  and  drug candidates that we  consider are important
to our business. This process is expensive  and  time-consuming,  and we may not be able to file and
prosecute all necessary or desirable patent  applications at a reasonable  cost or  in a timely manner. It  is
also possible that we will fail to identify patentable aspects of  our research and  development output
before it is too late to obtain patent protection.

The patent position of biotechnology and pharmaceutical  companies  generally is  highly uncertain,

involves complex legal and factual questions and has in recent years been  the subject of much litigation.
As a result, the issuance, scope, validity,  enforceability and commercial  value of our patent rights  are
highly uncertain. Our pending and future  patent applications  may  not  result in patents  being  issued
which  protect our technology or drug  candidates or which effectively  prevent others from
commercializing competitive technologies and drug candidates.  Changes in  either the patent laws or
interpretation of the patent laws in the United States and other countries may  diminish the value of
our  patents or narrow the scope of our  patent protection. Publications of discoveries in the scientific
literature often lag behind the actual discoveries,  and  patent  applications  in the United States and
other jurisdictions are typically not published until  18 months after filing, or in some cases  not  at all.
Therefore, we cannot be certain that  we were the first to make the inventions  claimed  in our patents or
pending patent applications, or that we  were  the first to file for patent protection  of such inventions.
Assuming the other requirements for  patentability are met, the first  to  file a patent application is
entitled to the patent. Under the Leahy-Smith  America Invents Act enacted in 2011,  the United  States
moved to this first-to-file system in early 2013 from  the previous system  under which  the first to make
the claimed invention was entitled to the patent. We may become involved in interference inter partes
review, post grant review,  ex parte reexamination, derivation, opposition or similar  other  proceedings
challenging our patent rights or the patent rights of  others. An adverse  determination in  any such
proceeding could reduce the scope of,  or  invalidate,  our patent  rights, allow third parties to
commercialize our technology or drug candidates and compete  directly with us, or result in our inability
to manufacture or commercialize drug candidates without infringing third-party patent rights.

There can be no assurance that our pending patent applications will result in issued patents in the
United States or non-U.S. jurisdictions in  which such  applications are pending.  Even if patents do issue
on any  of these applications, there can be no assurance that a third party will not challenge their
validity or that we will obtain sufficient  claim  scope  in  those patents to prevent  a third party from
competing successfully with our drug candidates. Even if  our patent applications issue  as patents, they
may not issue in a form that will provide us with any meaningful protection, prevent competitors from
competing with us or otherwise provide us with any competitive advantage. Our competitors may be
able to circumvent our patents by developing similar or alternative  technologies or drug  candidates in a

109

non-infringing manner. The issuance  of  a  patent is  not  conclusive  as to its scope, validity or
enforceability, and our owned and licensed  patents  may be challenged  in the  courts or  patent  offices in
the United States and abroad. Such challenges  may  result in  patent  claims  being  narrowed, invalidated
or held unenforceable, which could limit our ability to stop or prevent us from  stopping others from
using or commercializing similar or identical  technology and drug candidates,  or limit the duration of
the patent protection of our technology and drug candidates.  Given the amount of  time required for
the development, testing and regulatory review of new  drug  candidates, patents protecting such
candidates might expire before or shortly after such candidates are commercialized. As  a result, our
patent portfolio may not provide us with sufficient rights to exclude others from commercializing drug
candidates similar or identical to ours.

We may  not be able to protect our intellectual property rights throughout  the world.

Filing,  prosecuting, maintaining and  defending patents  on drug candidates in all countries
throughout the world could be prohibitively  expensive  for us, and our intellectual property rights  in
some non-U.S. countries can have a different scope and strength than do those  in the United States. In
addition, the laws of certain non-U.S.  countries do not protect intellectual property  rights to the same
extent as U.S. federal and state laws do.  Consequently,  we may not  be  able to prevent third  parties
from practicing our inventions in all countries outside the United  States, or from selling or importing
drugs made using our inventions in and into the United States or  non-U.S. jurisdictions. Competitors
may use our technologies in jurisdictions  where we have  not  obtained patent protection to develop
their own drugs and further, may export otherwise infringing drugs to non-U.S. jurisdictions where we
have patent protection, but where enforcement  rights are  not as strong as those in the  United States.
These drugs may compete with our drug  candidates and our patent rights  or other intellectual  property
rights may not be effective or adequate  to  prevent them from competing.

We  currently hold issued trademark registrations and have  trademark applications  pending,  any of

which  may be the subject of a governmental or  third-party objection, which could prevent the
maintenance or issuance of the same. If  we are unsuccessful in obtaining  trademark protection for our
primary brands, we may be required to change our brand name, which  could  materially adversely affect
our  business. Moreover, as our products  mature, our reliance on our trademarks to differentiate  us
from our competitors will increase, and  as a result, if we are  unable to prevent third parties  from
adopting, registering or using trademarks  and trade dress that infringe,  dilute or otherwise  violate our
trademark rights, our business could be materially adversely affected.

Many companies have encountered significant  problems in protecting and defending intellectual

property rights in certain jurisdictions, including China. The legal systems of some countries do not
favor the enforcement of patents, trade  secrets and other  intellectual property, particularly those
relating to biopharmaceutical products,  which could  make  it difficult in those  jurisdictions for  us to stop
the infringement or misappropriation of our patents or  other  intellectual  property rights, or  the
marketing of competing drugs in violation of our proprietary  rights.

Proceedings to enforce our patent and other intellectual property rights in non-U.S. jurisdictions

could result in substantial costs and divert  our efforts and attention from  other aspects of  our business.

Furthermore, such proceedings could put our patents  at risk of being invalidated,  held

unenforceable, or interpreted narrowly,  could put our  patent applications at  risk of not issuing,  and
could provoke third parties to assert claims  of infringement or misappropriation against  us.  We may not
prevail in any lawsuits that we initiate and the  damages or  other  remedies awarded, if any, may not be
commercially meaningful. Accordingly,  our  efforts to enforce our intellectual property rights  around the
world may be inadequate to obtain a  significant commercial advantage from  the intellectual  property
that we develop.

110

We may  become involved in lawsuits to protect  or enforce our intellectual property, which could be expensive,
time consuming and unsuccessful. Our patent rights  relating  to our drug candidates  could be found  invalid or
unenforceable if challenged in court or before the U.S.  Patent  and Trademark Office or  comparable non-U.S.
authority.

Competitors may infringe our patent rights or misappropriate or otherwise  violate our intellectual
property rights. To counter infringement  or unauthorized use, litigation  may be necessary in the  future
to enforce or defend our intellectual property rights, to protect our  trade secrets or to determine the
validity and scope of our own intellectual property rights  or the proprietary rights of others.  This can
be expensive and time consuming. Any  claims  that we assert against perceived infringers could also
provoke these parties to assert counterclaims against us alleging that we infringe their  intellectual
property rights. Many of our current and potential competitors have  the ability to dedicate substantially
greater resources to enforce and/or defend  their  intellectual property rights than  we can. Accordingly,
despite our efforts, we may not be able to prevent third parties from infringing upon or
misappropriating our intellectual property. Litigation  could result in  substantial costs and  diversion of
management resources, which could harm  our business and  financial results.  In addition, in  an
infringement proceeding, a court may decide  that patent  rights or  other intellectual property  rights
owned by us are invalid or unenforceable, or  may refuse to stop the other party from  using the
technology at issue on the grounds that our patent rights or other intellectual property rights  do  not
cover the technology in question. An adverse result in any litigation proceeding could put our  patent,
as well as any patents that may issue in  the future from our pending patent applications, at risk  of
being invalidated, held unenforceable or  interpreted  narrowly. Furthermore, because of the  substantial
amount of discovery required in connection with intellectual property litigation, there is a risk that
some of our confidential information  could be compromised  by disclosure  during  this  type of litigation.

If we  initiate legal proceedings against a third party  to  enforce our patent, or any patents that may

issue in the future from our patent applications, that relates  to  one  of  our  drug candidates, the
defendant could counterclaim that such  patent rights are invalid  or  unenforceable. In  patent  litigation
in the United States, defendant counterclaims alleging  invalidity  or unenforceability  are commonplace,
and there are numerous grounds upon  which a third party can assert invalidity or unenforceability of a
patent. Third parties may also raise similar  claims  before  administrative bodies in  the United States  or
abroad, even outside the context of litigation. Such mechanisms include ex parte re-examination, inter
partes review, post-grant review, derivation and equivalent  proceedings  in non-U.S.  jurisdictions, such as
opposition proceedings. Such proceedings  could result in revocation  or amendment to our patents in
such a way that they no longer cover  and  protect our drug candidates.  The outcome following legal
assertions of invalidity and unenforceability  is unpredictable. With respect  to  the validity of our patents,
for example, we cannot be certain that  there  is no  invalidating prior art  of which  we, our patent
counsel, and the patent examiner were  unaware during prosecution. If a defendant were to prevail on  a
legal assertion of invalidity and/or unenforceability, we would lose at least part,  and perhaps all, of the
patent protection on our drug candidates.  Such a  loss of  patent  protection could have a  material
adverse impact on our business.

We  may not be able to prevent misappropriation of our trade  secrets or confidential information,

particularly in countries where the laws  may not protect  those rights as fully as in  the United  States.
Furthermore, because of the substantial  amount of  discovery required in connection with intellectual
property litigation, there is a risk that  some of our confidential information  could  be  compromised by
disclosure during this type of litigation.

We may  be subject to claims challenging the  inventorship of our patents  and other  intellectual property.

Although we are not currently experiencing any  claims challenging the inventorship of our patents

or ownership of our intellectual property,  we may in the  future be subject to claims that former
employees, collaborators or other third  parties have an  interest  in our  patents or other intellectual

111

property as inventors or co-inventors.  For example, we  may  have inventorship  disputes arise from
conflicting obligations of consultants or others who are involved in developing our drug candidates.
Litigation may be necessary to defend  against  these and other claims  challenging  inventorship. If we
fail in defending any such claims, in addition to paying  monetary damages, we may lose rights such as
exclusive ownership of, or right to use, our patent rights or other intellectual property. Such an
outcome could have a material adverse  effect  on our business. Even  if we are  successful in  defending
against such claims, litigation could result  in substantial  costs and be a distraction to management  and
other employees.

If we are sued for infringing intellectual  property  rights  of third parties, such litigation could be  costly and
time consuming and could prevent or delay us  from  developing or commercializing our drug candidates.

Our commercial success depends in part on our  avoiding infringement of the patents and other

intellectual property rights of third parties.  There is a substantial  amount of  litigation  involving patent
and other intellectual property rights in the  biotechnology  and pharmaceutical industries, including inter
partes review, post grant review, interference and  ex parte reexamination proceedings before the
USPTO or oppositions and other comparable proceedings in non-U.S. jurisdictions. Numerous issued
patents and pending patent applications, which are owned  by third  parties, exist  in the fields in which
we are developing drug candidates. As the  biotechnology and pharmaceutical industries  expand  and
more patents are issued, the risk increases  that our drug candidates may give  rise to claims of
infringement of the patent rights of others.

Third parties may assert that we are  employing their proprietary technology without  authorization.

There may be third-party patents of which we  are currently unaware  with claims to materials,
formulations, methods of manufacture  or  methods  for treatment  related to the  use or manufacture  of
our  drug candidates. Because patent  applications can  take many years to  issue, there may be currently
pending patent applications which may later result in  issued patents that our drug candidates may
infringe. In addition, third parties may  obtain  patents  in the future  and claim that use of our
technologies infringes upon these patents.  If any third-party patents were held by a  court of competent
jurisdiction to cover the manufacturing process of any of our drug candidates, any molecules formed
during the manufacturing process or  any final product  itself, the holders  of  any such patents may be
able to prevent us from commercializing  such drug candidate unless we obtain  a license  under the
applicable patents, or until such patents expire  or they  are finally determined to be held invalid  or
unenforceable. Similarly, if any third-party  patent  were  held by a court of competent jurisdiction to
cover aspects of our formulations, processes for manufacture  or methods  of use, including combination
therapy or patient selection methods, the holders of any such  patent  may be able  to  block our ability to
develop and commercialize the applicable  drug candidate  unless we obtain  a license,  limit  our  uses, or
until such patent expires or is finally  determined  to  be  held invalid or unenforceable. In either case,
such a license may not be available on  commercially reasonable  terms or  at all.

Third parties who bring successful claims  against us for infringement of  their intellectual property

rights may obtain injunctive or other equitable relief, which could prevent  us  from developing and
commercializing one or more of our  drug candidates.  Defense  of these  claims, regardless of their merit,
would involve substantial litigation expense and  would be a substantial diversion  of  employee resources
from our business. In the event of a successful claim of infringement or  misappropriation  against us,  we
may have to pay substantial damages, including treble  damages  and attorneys’  fees  in the case  of  willful
infringement, obtain one or more licenses from third  parties, pay royalties or redesign our infringing
drug candidates, which may be impossible  or require substantial time and monetary expenditure. In  the
event of an adverse result in any such litigation,  or even in  the absence of litigation, we  may need to
obtain licenses from third parties to advance our  research or allow  commercialization of our drug
candidates. We cannot predict whether any required license would be available  at all or whether  it
would be available on commercially reasonable terms, and we may fail to obtain any of these licenses

112

on commercially reasonable terms, if  at  all. In the event that  we  are unable to obtain such a license,  we
would be unable to further develop and commercialize one or more of our drug candidates,  which
could harm our business significantly. We may also elect to enter into  license agreements in order to
settle patent infringement claims or to  resolve  disputes prior  to  litigation, and any  such license
agreements may require us to pay royalties and other fees  that could significantly harm our  business.

Specifically, we are aware of three U.S. patents  owned by Ono  Pharmaceutical  Co., or Ono,  and

licensed to Bristol-Myers Squibb Co., or  BMS,  that are relevant to our  BGB-A317  drug candidate.
These patents are expected to expire  in  2023, 2023 and 2024, respectively. In patent infringement
actions filed in Delaware Federal District  court,  BMS  and Ono alleged that Merck & Co.’s
KEYTRUDA product, a humanized  anti-PD-1 antibody is  infringing these U.S.  patents. Although
Merck challenged  the validity of these patents,  Merck recently  settled  this litigation with BMS and Ono
resulting in Merck taking a license from BMS  and  Ono. All these three patents remain  presumed valid
and enforceable. Merck also filed an  opposition  proceeding challenging a  corresponding  European
patent at the European Patent Office, or  EPO. The EPO’s  Opposition  Division disagreed with  Merck’s
arguments and maintained the European  patent  in the form in which  it was  granted. Merck appealed
the decision, but recently withdrew its appeal. If the  validity  of the relevant claims in these U.S. patents
is upheld  and our  BGB-A317 drug candidate  is approved for  sale in the United  States before  the
expiration of these patents, then we will need a  license from  BMS in  order  to  commercialize our
BGB-A317 drug candidate in the United  States prior  to  their expiration. In addition, depending upon
circumstances, we may need a license  for jurisdictions outside the  United States where we  wish to
commercialize BGB-A317 before the expiration of a  corresponding  patent  covering BGB-A317. There
can be no assurance that we will be able to obtain such  a license, which could materially  and adversely
affect our business.

In addition, we are aware of a U.S. patent owned by Pharmacyclics, Inc., which  was acquired  by

AbbVie, Inc., with certain claims directed  to  a complex of  an irreversible BTK inhibitor having  a
covalent  bond to a cysteine residue of  a  BTK.  This patent is  expected to expire in  2027. Although  we
believe that the claims of the patent  relevant to our  BGB-3111  drug candidate would likely be held
invalid, we cannot provide any assurances that  a court  or an administrative agency would agree with
our  assessment. If the validity of the relevant claims in  question is upheld  upon a  validity  challenge,
and BGB-3111 is approved for sale in the  United States before the  expiration of the  U.S. patent, then
we would need a license in order to commercialize BGB-3111 in the  United States. In addition,
depending upon circumstances, we may  need a license for jurisdictions outside the United States where
we wish to commercialize BGB-3111 before the expiration of a corresponding  patent  covering
BGB-3111. However such a license may  not be available on commercially  reasonable  terms or at all,
which  could materially and adversely  affect our business.

We  are also aware of three U.S. patents,  owned or licensed by KuDOS Pharmaceuticals, Ltd.,

which  was acquired by AstraZeneca PLC, with claims directed  to  using PARP inhibitors to treat
cancers with certain defects in homologous recombination including, in some cases,  a BRCA1  or
BRCA2 mutation. These patents are  expected to expire  between  2027 and 2031 in  the United  States.
Although we believe that the claims  of these  patents relevant  to  our BGB-290 drug candidate would
likely be held invalid, we cannot provide  any  assurances that a court or an administrative  agency would
agree with our assessment. While we  are  currently  conducting  and plan to conduct studies  that  include
cancer patients with a BRCA1 or BRCA2 mutation,  we are uncertain  whether BGB-290  as
commercialized will be used to treat cancer patients limited to having BRCA1 or BRCA2 mutation
either in a monotherapy or a combination  therapy. If  BGB-290  is approved for sale in the  United
States for patients whose cancers have  a BRCA1 or BRCA2  mutation, and if the validity of the
relevant claims of these U.S. patents is  upheld upon  a validity challenge,  then we would need  a license
in order to commercialize BGB-290 prior to expiration  of  these U.S. patents. In addition, we are also
aware of corresponding issued patents in Europe  and  China.  Depending upon circumstances, we  may

113

need a license for jurisdictions outside the  United States where we wish to commercialize BGB-290
before the expiration of a corresponding patent covering BGB-290. However, such  a license  may not be
available on commercially reasonable terms or  at all, which could materially and adversely  affect our
business.

Even if resolved in our favor, litigation or  other  legal proceedings relating to intellectual property

claims may cause us to incur significant expenses, and could distract our technical  personnel,
management personnel, or both from  their  normal responsibilities.  In  addition, there could be public
announcements of the results of hearings, motions or other  interim proceedings  or developments and if
securities analysts or investors perceive  these results to be negative, it could have a substantial adverse
effect on the market price of the ADSs.  Such litigation or  proceedings could substantially increase  our
operating losses and reduce the resources available for development activities or any future  sales,
marketing or distribution activities. We may not  have sufficient  financial or other resources to
adequately conduct such litigation or proceedings. Some of our competitors may  be  able to sustain the
costs of such litigation or proceedings more effectively than we can because  of their  greater  financial
resources. Uncertainties resulting from  the initiation and continuation of  patent litigation or other
proceedings could have a material adverse effect on our ability to compete in  the marketplace.

Obtaining and maintaining our patent  protection depends on compliance with  various procedural, document
submission, fee payment, and other requirements imposed by governmental patent agencies, and our  patent
protection could be reduced or eliminated  for noncompliance with these requirements.

Periodic maintenance fees on any issued patent are due to be paid to the  USPTO and other patent

agencies in several stages over the lifetime of the patent. The USPTO and various non-U.S.
governmental patent agencies require  compliance with a  number  of procedural, documentary, fee
payment, and other similar provisions during  the patent application process.  Although an  inadvertent
lapse can in many cases be cured by payment of a late  fee or by  other  means in  accordance  with the
applicable rules, there are situations  in which  noncompliance can result  in abandonment or  lapse of the
patent or patent application, resulting in partial or  complete  loss of  patent  rights in  the relevant
jurisdiction. Noncompliance events that  could result  in abandonment  or  lapse of a patent or  patent
application include failure to respond  to  official actions  within prescribed time limits, non-payment of
fees, and failure to properly legalize and submit formal documents. In any such event, our competitors
might be able to enter the market, which would have  a material adverse effect on our business.

The terms of our patents may not be sufficient  to effectively protect our drug candidates and business.

In most countries in which we file, including the United States, the term  of an issued patent is

generally 20 years from the earliest claimed filing date of a non-provisional patent application in  the
applicable country. Although various  extensions may be available, the  life of a patent and the
protection it affords, is limited. Even  if  patents covering our  drug candidates are obtained, we may  be
open to competition from other companies as well  as generic medications once the patent life has
expired for a drug. If patents are issued on our  currently  pending  patent  applications,  the resulting
patents will be expected to expire on  dates ranging from 2031 to 2035,  excluding any  potential  patent
term extension or adjustment. Upon  the expiration  of our issued  patent or patents that may  issue from
our  pending patent applications, we will not be able to assert such patent rights against  potential
competitors and our business and results of operations may be adversely affected.

If we do not obtain additional protection under the Hatch-Waxman Amendments  and  similar  legislation  in
other countries extending the terms of our patents,  if issued, relating to  our drug  candidates, our business may
be materially harmed.

Depending upon the timing, duration and specifics of FDA regulatory approval for our drug

candidates, one or more of our U.S. patents, if issued, may be eligible for limited patent term

114

restoration under the Drug Price Competition  and  Patent Term  Restoration Act of  1984, referred  to  as
the Hatch-Waxman Amendments. The Hatch-Waxman Amendments  permit a patent term extension of
up to five years as compensation for  patent  term lost during drug development  and the  FDA regulatory
review process. Patent term extensions,  however,  cannot extend  the  remaining  term of a patent beyond
a total of 14 years from the date of drug approval by the FDA, and only one patent can be extended
for a particular drug.

The application for patent term extension is  subject to approval by  the USPTO,  in conjunction
with the FDA. We may not be granted  an extension because  of, for example, failing  to  apply within
applicable deadlines, failing to apply prior  to expiration of relevant patents or otherwise failing to
satisfy applicable requirements. Moreover, the applicable time period or the scope of patent protection
afforded could be less than we request.  If  we  are unable to obtain  a patent term extension  for a  given
patent or the term of any such extension is less  than  we request, the  period during which we  will have
the right to exclusively market our drug  will  be  shortened and our  competitors may obtain earlier
approval of competing drugs, and our  ability to generate revenues  could be materially adversely
affected.

Changes in patent law could diminish the value of patents in general, thereby impairing  our  ability to protect
our drug candidates.

As is the case with other biopharmaceutical companies, our  success is heavily dependent on

intellectual property, particularly patent rights.  Obtaining and enforcing patents in  the
biopharmaceutical industry involves both  technological and legal  complexity, and  is therefore costly,
time-consuming, and inherently uncertain. In addition, the United States has recently  enacted and is
currently implementing wide-ranging  patent reform legislation.  Recent U.S.  Supreme  Court rulings have
narrowed the scope of patent protection  available  in certain circumstances  and weakened the rights  of
patent owners in certain situations. In  addition to increasing uncertainty with regard to our  ability to
obtain patents in the future, this combination of events has created uncertainty with respect to the
value of patents once obtained, if any.  Depending  on decisions  by the  U.S. Congress, the federal courts
and the USPTO, the laws and regulations governing  patents could  change in unpredictable ways that
would weaken our ability to obtain new patents  or to enforce our existing  patents and  patents  that  we
might obtain in the future. For example,  in a  recent case, Assoc. for Molecular Pathology v. Myriad
Genetics, Inc., the U.S. Supreme Court held that certain claims  to  naturally-occurring substances are
not patentable. Although we do not believe  that our currently-issued patent and any patents that may
issue from our pending patent applications directed  to  our drug candidates if  issued in their currently
pending forms, as well as patent rights  licensed by us, will be found invalid based on this decision, we
cannot predict how future decisions by the courts, the U.S. Congress or the USPTO may impact the
value of our patent rights. There could be similar changes in  the laws of foreign jurisdictions  that  may
impact the value of our patent rights or  our other intellectual property rights.

If we are unable to protect the confidentiality of  our trade secrets,  our business and competitive  position would
be harmed. We may be subject to claims  that our employees  have wrongfully used or disclosed alleged trade
secrets of their former employers.

In addition to our issued patent and pending  patent  applications, we rely on trade secrets,
including unpatented know-how, technology and other proprietary information, to maintain our
competitive position and to protect our drug candidates.  We seek to protect these trade secrets, in part,
by entering into non-disclosure and confidentiality agreements with parties that have access to them,
such as our employees, corporate collaborators,  outside scientific collaborators, sponsored researchers,
contract manufacturers, consultants, advisors and  other third parties.  We also enter into confidentiality
and invention or patent assignment agreements with our  employees and consultants. However, any of
these parties may breach such agreements and disclose  our proprietary information, and we may not be

115

able to obtain adequate remedies for  such breaches.  Enforcing a claim that a party  illegally disclosed or
misappropriated a trade secret can be  difficult, expensive and  time-consuming, and the outcome is
unpredictable. If any of our trade secrets  were to be lawfully obtained or independently developed by a
competitor, we would have no right to prevent them  from using that technology  or information  to
compete with us and our competitive  position would  be  harmed.

Furthermore, many of our employees, including our senior  management, were previously employed

at other biotechnology or pharmaceutical companies, including our competitors or potential
competitors. Some of these employees, including each member of  our senior management, executed
proprietary rights, non-disclosure and non-competition  agreements in connection with such previous
employment. Although we try to ensure that  our employees do  not use the proprietary  information or
know-how of others in their work for  us, we may be subject  to  claims that  we or  these employees have
used or disclosed intellectual property,  including trade secrets or other proprietary information, of any
such employee’s former employer. We  are  not  aware of any threatened or pending  claims related to
these matters or concerning the agreements with our senior management, but in  the future  litigation
may be necessary to defend against such claims. If we fail in defending any such  claims,  in addition to
paying  monetary damages, we may lose  valuable intellectual property rights or personnel. Even if we
are successful in defending against such  claims, litigation could result in substantial costs  and be a
distraction to management.

In addition, while we typically require our employees, consultants and  contractors who may  be
involved in the development of intellectual property to execute  agreements assigning  such intellectual
property to us, we may be unsuccessful  in executing such an agreement  with each party who in fact
develops intellectual property that we regard  as our own,  which may  result in claims by or  against us
related to the ownership of such intellectual property. If we fail in  prosecuting or  defending  any such
claims, in addition to paying monetary damages, we  may lose valuable intellectual property  rights. Even
if we are successful in prosecuting or  defending  against such  claims, litigation could result in substantial
costs and be a distraction to our management and scientific personnel.

We may  not be successful in obtaining or maintaining necessary  rights for our development pipeline through
acquisitions and in-licenses.

Because our programs may involve additional  drug candidates that  may  require the use  of

proprietary rights held by third parties, the  growth of our business may  depend in  part on our ability to
acquire and maintain licenses or other rights to use these proprietary rights.  We may  be  unable to
acquire or in-license any compositions, methods of use, or other  third-party intellectual  property rights
from third parties that we identify. The licensing and acquisition of third-party  intellectual property
rights is a competitive area, and a number of more established companies  are also pursuing strategies
to license or acquire third-party intellectual property rights that we may consider attractive. These
established companies may have a competitive advantage  over  us due  to  their size, cash resources and
greater clinical development and commercialization capabilities.

In addition, companies that perceive us to be a competitor may be unwilling to assign or  license

rights to us. We also may be unable to license or acquire third-party intellectual property rights on
terms that would allow us to make an appropriate return on our  investment. If we are unable to
successfully obtain rights to required third-party intellectual property rights, our  business,  financial
condition and prospects for growth could  suffer.

116

If we fail to comply with our obligations in the agreements under which we license  intellectual property rights
from  third parties or otherwise experience disruptions to  our business relationships with  our  licensors, we
could be required to pay monetary damages or could lose license  rights that  are  important  to our business.

We  have entered into license agreements with  third parties providing  us with rights  under various
third-party patents and patent applications, including the rights to prosecute patent applications and  to
enforce patents. Certain of these license agreements  impose  and,  for a  variety of  purposes, we may
enter into additional licensing and funding arrangements with third parties that also  may impose,
diligence, development or commercialization timelines and milestone payment,  royalty, insurance  and
other obligations on us. Under certain  of  our existing  licensing agreements, we are obligated to pay
royalties on net product sales of our  drug candidates once commercialized,  pay a percentage of
sublicensing revenues, make other specified payments  relating to our drug candidates or pay license
maintenance and other fees. We also have  diligence  and  clinical  development  obligations under  certain
of these  agreements that we are required  to satisfy. If we fail  to  comply  with our obligations  under our
current or future license agreements, our counterparties may have the right to terminate these
agreements, in which event we might not be able to develop, manufacture  or market  any drug  or drug
candidate that is covered by the licenses provided for under  these  agreements or we  may face  claims
for monetary damages or other penalties under  these agreements. Such  an occurrence could diminish
the value of these products and our company.  Termination of the licenses  provided for under these
agreements or reduction or elimination  of our rights under  these  agreements may result  in our having
to negotiate new or reinstated agreements with less favorable  terms, or cause  us  to  lose our  rights
under these agreements, including our rights to important  intellectual property  or technology.

Risks Related to Our Reliance on Third Parties

We rely on third parties to conduct our preclinical studies and clinical  trials. If  these third parties do  not
successfully carry out their contractual duties or meet  expected deadlines,  we may not be able to obtain
regulatory approval for or commercialize our drug candidates and our business could be  substantially harmed.

We  have relied upon and plan to continue to rely upon third-party  CROs  to  monitor and manage

data for our ongoing preclinical and  clinical programs. We rely on these parties for  execution of our
preclinical studies and clinical trials, and control only certain  aspects of their activities. Nevertheless,  we
are responsible for ensuring that each of our  studies is conducted in  accordance with the  applicable
protocol, legal and regulatory requirements and scientific  standards,  and our  reliance  on the  CROs
does not relieve us of our regulatory  responsibilities.  We and  our CROs and our clinical investigators
are required to comply with GCPs, which are regulations and  guidelines enforced by the  FDA, CFDA,
EMA and other comparable regulatory  authorities for all of our drugs in  clinical development.
Regulatory authorities enforce these GCPs through periodic inspections of trial sponsors,  principal
investigators and trial sites. If we or  any  of  our CROs  or clinical  investigators fail  to  comply with
applicable GCPs, the clinical data generated in our  clinical trials may be deemed  unreliable and  the
FDA, CFDA, EMA or comparable regulatory  authorities  may  require us to perform additional clinical
trials before approving our marketing  applications. We  cannot assure you that upon  inspection by a
given regulatory authority, such regulatory authority will determine that any of our clinical  trials comply
with GCP regulations. In addition, our  clinical trials must be conducted with  product produced under
cGMP regulations. Our failure to comply with these  regulations may  require us to repeat clinical  trials,
which  would delay the regulatory approval  process.

Our CROs have the right to terminate their  agreements with  us in the event  of an uncured

material breach. In addition, some of our  CROs have an ability to terminate their respective
agreements with us if it can be reasonably demonstrated  that the safety of the  subjects participating in
our  clinical trials warrants such termination, if we  make a general assignment  for the  benefit of our
creditors or if we are liquidated.

117

If any of our relationships with these third-party  CROs terminate, we  may not be able  to  enter
into arrangements with alternative CROs or to do so on  commercially reasonable terms. In addition,
our  CROs are not our employees, and except for remedies available  to  us  under our agreements  with
such CROs, we cannot control whether  or not they  devote sufficient time and  resources  to  our  ongoing
clinical, nonclinical and preclinical programs.  If CROs do not successfully carry out their contractual
duties or obligations or meet expected deadlines, if they need to be replaced  or if the quality  or
accuracy of the clinical data they obtain is  compromised  due to the  failure to adhere  to  our clinical
protocols, regulatory requirements or for  other  reasons, our clinical trials may  be  extended, delayed  or
terminated and we may not be able to  obtain regulatory  approval for or successfully commercialize  our
drug candidates. As a result, our results  of operations and the commercial prospects for our drug
candidates would be harmed, our costs  could increase and  our ability to generate revenues could be
delayed.

Switching or adding additional CROs  involves additional cost and requires  management time and
focus. In addition, there is a natural  transition period when a new  CRO commences work.  As a result,
delays occur, which can materially influence  our  ability to meet our desired clinical  development
timelines. Though we carefully manage our relationships with  our CROs,  there can  be  no assurance
that we will not encounter similar challenges or delays in the  future or that  these  delays or  challenges
will not have a material adverse effect  on  our business, financial condition and prospects.

We expect to rely on third parties to manufacture at least a portion of our drug  candidate  supplies, and we
intend to rely on third parties for at least a  portion of the manufacturing process  of our drug candidates, if
approved. Our business could be harmed  if those third parties fail to provide us with  sufficient quantities of
product or fail to do so at acceptable quality levels  or prices.

Although we currently have a facility that  may  be  used  as our clinical-scale manufacturing and
processing facility, we intend to at least partially  rely on outside  vendors to  manufacture supplies  and
process our drug candidates. We have  not yet  caused our  drug  candidates to be manufactured or
processed on a commercial scale and may not  be  able  to  do  so for any  of our drug candidates.  We have
limited experience in managing the manufacturing process, and our  process  may be more difficult or
expensive than the approaches currently in use.

Although we intend to further develop our own manufacturing facilities,  we  also intend to use
third parties as part of our manufacturing process. Our anticipated reliance on  a limited number  of
third-party manufacturers exposes us  to  the following risks:

(cid:129) we may be unable to identify manufacturers on  acceptable  terms or at all because the  number of
potential manufacturers is limited and the  FDA,  CFDA,  EMA  or  other  comparable regulatory
authorities must approve any manufacturers as part of their regulatory oversight of our drug
candidates. This approval would require new testing and cGMP-compliance inspections  by  FDA,
CFDA, EMA or other comparable regulatory authorities.  In addition, a new manufacturer would
have to be educated in, or develop substantially equivalent processes  for, production of our
drugs;

(cid:129) our manufacturers may have little or no  experience  with manufacturing our drug candidates,  and

therefore may require a significant amount  of support from us in order  to implement and
maintain the infrastructure and processes required  to  manufacture our drug candidates;

(cid:129) our third-party manufacturers might be unable to timely manufacture  our drug candidates or
produce the quantity and quality required  to  meet our clinical and commercial  needs,  if  any;

(cid:129) contract manufacturers may not be able to execute our manufacturing procedures and  other

logistical support requirements appropriately;

118

(cid:129) our future contract manufacturers may not perform as  agreed, may  not devote sufficient

resources to our drugs, or may not remain  in the contract manufacturing business for  the time
required to supply our clinical trials or to successfully produce, store and distribute our drugs;

(cid:129) manufacturers are subject to ongoing  periodic  unannounced inspection by the  FDA and

corresponding state agencies in the United  States  to  ensure strict  compliance with  cGMPs and
other government  regulations and by other comparable regulatory authorities for corresponding
non-U.S. requirements. We do not have control over third-party manufacturers’ compliance  with
these regulations and requirements;

(cid:129) we may not own, or may have to share,  the intellectual property rights  to any improvements

made by our third-party manufacturers in the manufacturing process for our drugs;

(cid:129) our third-party manufacturers could breach or  terminate their agreement with  us;

(cid:129) raw  materials and components used  in the manufacturing process, particularly  those for which

we have no other source or supplier, may not be available or may  not  be  suitable  or acceptable
for use due to material or component  defects;

(cid:129) our contract manufacturers and critical reagent  suppliers may be subject to inclement  weather,

as well as natural or man-made disasters;  and

(cid:129) our contract manufacturers may have unacceptable  or inconsistent product quality success rates

and yields.

Each  of these risks could delay or prevent  the completion of our clinical trials or the  approval of

any of our drug candidates by the FDA,  CFDA, EMA or other comparable regulatory  authorities,
result in higher costs or adversely impact commercialization of our drug candidates.  In addition, we will
rely on third parties to perform certain  specification tests  on our drug  candidates prior to delivery  to
patients. If these tests are not appropriately  done and test data  are  not reliable, patients could be put
at risk of  serious harm and the FDA,  CFDA, EMA  or other comparable regulatory authorities could
place significant restrictions on our company until deficiencies are remedied.

The manufacture of drug and biological products is complex and requires significant  expertise and

capital investment, including the development of advanced manufacturing techniques and process
controls.

Currently, our drug raw materials for our manufacturing activities are supplied by multiple source

suppliers. We have agreements for the  supply of drug materials with manufacturers or suppliers that we
believe have sufficient capacity to meet  our demands. In addition, we  believe that adequate alternative
sources  for such supplies exist. However,  there is  a risk that,  if supplies are  interrupted,  it would
materially harm our business.

Manufacturers of drug and biological  products often encounter  difficulties  in production,

particularly in scaling up or out, validating the production process, and  assuring  high reliability of the
manufacturing process (including the absence of contamination). These  problems  include logistics and
shipping, difficulties with production  costs  and  yields, quality control, including stability of  the product,
product  testing, operator error, availability of qualified personnel, as well as compliance with strictly
enforced federal, state and non-U.S.  regulations. Furthermore,  if contaminants are discovered in our
supply of  our drug candidates or in the  manufacturing  facilities, such manufacturing facilities may need
to be closed for an extended period of time to investigate  and remedy the contamination. We cannot
assure you that any stability failures or other issues relating  to  the manufacture of our drug candidates
will not occur in the future. Additionally,  our manufacturers  may  experience  manufacturing difficulties
due to resource constraints or as a result of labor disputes or unstable political environments.  If our
manufacturers were to encounter any of these difficulties, or otherwise fail to comply with their
contractual obligations, our ability to provide our drug candidate  to  patients in clinical trials would  be

119

jeopardized. Any delay or interruption in the  supply of clinical  trial supplies  could  delay the completion
of clinical trials, increase the costs associated  with maintaining clinical trial programs and, depending
upon the period of delay, require us  to  begin  new clinical trials at additional  expense or  terminate
clinical trials completely.

If third-party manufacturers fail to comply with manufacturing regulations,  our  financial  results and financial
condition will be adversely affected.

Before a third party can begin commercial manufacture of  our drug candidates and potential

drugs, contract manufacturers are subject to regulatory inspections  of their manufacturing  facilities,
processes and quality systems. Due to  the complexity of the processes used to manufacture drug and
biological products and our drug candidates,  any potential third-party manufacturer may be unable  to
initially pass federal, state or international  regulatory inspections in a cost effective manner in order for
us to obtain regulatory approval of our drug candidates.  If our contract manufacturers do not pass their
inspections by the FDA, CFDA, EMA  or other comparable  regulatory authorities, our commercial
supply of  drug product or substance  will  be  significantly  delayed and may result in significant additional
costs, including the delay or denial of any marketing application for our drug candidates.  In addition,
drug and biological manufacturing facilities  are continuously subject  to  inspection by the FDA,  CFDA,
EMA and other comparable regulatory  authorities, before and after drug approval,  and must comply
with cGMPs. Our contract manufacturers may  encounter difficulties in achieving quality control and
quality assurance and may experience shortages in qualified  personnel. In addition, contract
manufacturers’ failure to achieve and maintain high manufacturing standards in  accordance  with
applicable regulatory requirements, or the incidence of manufacturing errors,  could  result in patient
injury, product liability claims, product shortages, product  recalls  or  withdrawals, delays  or failures in
product  testing or delivery, cost overruns  or other  problems that  could seriously harm  our business. If a
third-party manufacturer with whom we contract is  unable to comply with manufacturing  regulations,
we may also be subject to fines, unanticipated compliance expenses,  recall or seizure of our drugs,
product  liability claims, total or partial suspension of production and/or enforcement actions, including
injunctions, and criminal or civil prosecution. These  possible sanctions could  materially adversely affect
our  financial results and financial condition.

Furthermore, changes in the manufacturing process or  procedure,  including a change  in the
location where the product is manufactured or  a change of a  third-party manufacturer, could require
prior review by the FDA, CFDA, EMA or other comparable regulatory  authorities  and/or approval  of
the manufacturing process and procedures in  accordance with  the FDA,  CFDA  or EMA’s  regulations,
or comparable requirements. This review  may be costly  and time consuming and could delay  or prevent
the launch of a product. The new facility  will also be subject to pre-approval  inspection. In addition, we
have to demonstrate that the product  made  at the  new facility is equivalent to the  product made at  the
former facility by physical and chemical  methods,  which are costly  and  time consuming. It  is also
possible that the FDA, CFDA, EMA  or  other  comparable  regulatory authorities  may require clinical
testing as a way to prove equivalency,  which would  result in additional costs and  delay.

We have  entered into collaborations and may form or  seek  collaborations or strategic alliances or enter into
additional licensing arrangements in the future, and we  may  not realize  the  benefits of  such  alliances or
licensing arrangements.

We  may form or seek strategic alliances,  create joint ventures or  collaborations,  or enter into
additional licensing arrangements with  third parties that we  believe will complement  or augment our
development and commercialization efforts  with respect to  our drug candidates and any  future drug
candidates that we may develop. Any of these relationships  may  require us to incur non-recurring and
other charges, increase our near and long-term  expenditures,  issue securities  that  dilute our existing
shareholders, or disrupt our management and  business.  For example, in 2013, we entered into

120

collaboration agreements with Merck  KGaA, Darmstadt Germany pursuant  to  which we have agreed to
license the ex-China rights of BGB-283  to  Merck KGaA, Darmstadt  Germany as  discussed further  in
the section titled ‘‘Item 1—Business—Collaboration with  Merck KGaA, Darmstadt Germany’’ in  this
Annual Report. In addition, we face  significant competition in  seeking  appropriate  strategic partners
and the negotiation process is time-consuming and complex. Moreover,  we may not be successful in our
efforts to establish a strategic partnership or other alternative  arrangements for our drug candidates
because they may be deemed to be at too  early of a  stage  of development for collaborative effort and
third parties may not view our drug candidates as having the  requisite potential  to  demonstrate  safety
and efficacy. If and when we collaborate  with a  third party  for  development and  commercialization of a
drug candidate, we can expect to relinquish some or all of the control over the  future success of that
drug candidate to the third party.

Further, collaborations involving our  drug  candidates are  subject to numerous  risks, which may

include the following:

(cid:129) collaborators have significant discretion in determining  the efforts and resources that they will

apply  to a collaboration;

(cid:129) collaborators may not pursue development and commercialization  of  our  drug candidates or  may
elect not to continue or renew development or commercialization  programs  based on  clinical
trial results, changes in their strategic focus due to the acquisition of competitive  drugs,
availability of funding, or other external factors,  such as  a business  combination that diverts
resources or creates competing priorities;

(cid:129) collaborators may delay clinical trials, provide  insufficient funding for a clinical trial, stop a

clinical trial, abandon a drug candidate, repeat or  conduct  new clinical trials, or  require a new
formulation of a drug candidate for clinical  testing;

(cid:129) collaborators could independently develop, or  develop  with third parties,  drugs that compete

directly or indirectly with our drugs or drug candidates;

(cid:129) a collaborator with marketing and distribution rights to one or more drugs may not commit

sufficient resources to their marketing and distribution;

(cid:129) collaborators may not properly maintain  or defend our intellectual property  rights or may  use

our  intellectual property or proprietary information in  a way  that gives rise to actual or
threatened litigation that could jeopardize or  invalidate  our intellectual property or  proprietary
information or expose us to potential  liability;

(cid:129) disputes may arise between us and a collaborator that  cause the delay or termination  of the
research, development or commercialization of our drug candidates,  or  that result in costly
litigation or arbitration that diverts management  attention and resources;

(cid:129) collaborations may be terminated and, if  terminated, may  result  in a need  for additional capital
to pursue further development or commercialization of the applicable drug candidates; and

(cid:129) collaborators may own or co-own intellectual property covering our drugs that results from our

collaborating with them, and in such cases, we would not have the  exclusive  right to
commercialize such intellectual property.

As a result, if we enter into collaboration agreements  and strategic partnerships or license our

drugs, we may not be able to realize the  benefit of such transactions if  we are  unable to successfully
integrate them with our existing operations and company culture,  which could delay our  timelines or
otherwise adversely affect our business.  We  also cannot be certain  that, following  a strategic transaction
or license, we will achieve the revenue or  specific net  income that justifies such transaction. If we are
unable to reach agreements with suitable collaborators on  a  timely  basis, on acceptable terms, or  at all,

121

we may have to curtail the development  of a drug candidate, reduce or  delay its development program
or one or more of our other development programs, delay its  potential  commercialization or  reduce the
scope of any sales or marketing activities, or  increase our expenditures and  undertake  development or
commercialization activities at our own expense. If we  elect to fund and undertake development  or
commercialization activities on our own, we  may  need  to  obtain  additional expertise and  additional
capital, which may not be available to  us on acceptable terms  or at  all. If we fail to enter into
collaborations and do not have sufficient funds or expertise to undertake the necessary development
and commercialization activities, we may  not be able to further develop our drug candidates or  bring
them to market and generate product sales revenue, which would harm our  business  prospects,
financial condition and results of operations.

Risks Related to Our Industry, Business and  Operations

Our future success depends on our ability to retain the  Chairman of our  scientific  advisory board and  our
Chief Executive Officer and other key executives and to attract, retain and motivate qualified personnel.

We  are highly dependent on Xiaodong Wang, Ph.D., our Founder, Chairman of our scientific
advisory board and director; John V.  Oyler, our  Founder,  Chief Executive Officer and  Chairman of  the
board; and the other principal members of  our  management and  scientific  teams and scientific  advisory
board. Although we have formal employment agreements with each of  our executive officers except for
our  Chief Executive Officer, these agreements do not prevent our executives from terminating  their
employment with us at any time. We  do not maintain ‘‘key person’’ insurance for  any of our executives
or other  employees. The loss of the services of any of these persons could impede the  achievement of
our  research, development and commercialization objectives.

To induce valuable employees to remain at our company, in  addition  to  salary and  cash incentives,

we have provided share option grants that  vest over  time. The value to employees of these equity
grants that vest over time may be significantly  affected by movements in the ADS  price that are beyond
our  control, and may at any time be  insufficient to counteract more  lucrative offers  from other
companies. Although we have employment agreements with our  key  employees, any  of our  employees
could leave our employment at any time,  with  or without notice.

Recruiting and retaining qualified scientific, clinical,  manufacturing and sales and marketing
personnel or consultants will also be critical to our success. In  addition,  we rely on  consultants and
advisors, including scientific and clinical  advisors, to assist us  in formulating our discovery  and
preclinical development and commercialization  strategy. The loss of the  services  of our  executive
officers or other key employees and consultants could impede the achievement  of our  research,
development and commercialization objectives and seriously  harm  our ability to successfully implement
our  business strategy.

Furthermore, replacing executive officers and  key  employees or consultants may be difficult and
may take an extended period of time because of the limited number  of  individuals in  our  industry  with
the breadth of skills and experience required to successfully develop, gain regulatory  approval of and
commercialize products. Competition  to  hire  from this limited  pool is intense, and we may be unable to
hire, train, retain or motivate these key  personnel or  consultants  on  acceptable terms given the
competition among numerous pharmaceutical and biotechnology companies  for similar personnel.

We  also experience competition for the hiring of  scientific and  clinical personnel from  universities

and research institutions. Our consultants  and advisors may  be  employed by employers  other  than us
and may have commitments under consulting or  advisory  contracts  with other entities that may  limit
their availability to us. If we are unable  to continue  to  attract and retain  high quality  personnel, our
ability to pursue our growth strategy  will  be limited.

122

We will need to increase the size and capabilities of  our organization,  and we may experience difficulties in
managing our growth.

As of December 31, 2016, we had 348  employees and consultants and most  of  our  employees are

full-time. As our development and commercialization plans and  strategies develop, and as we transition
into operating as a public company, we  must add a significant number  of additional managerial,
operational, sales, marketing, financial and other personnel. Future growth will impose  significant
added responsibilities on members of  management, including:

(cid:129) identifying, recruiting, integrating,  maintaining, and motivating additional employees;

(cid:129) managing our internal development efforts effectively, including the clinical and FDA or other
comparable regulatory authority review  process for our drug  candidates, while complying  with
our  contractual obligations to contractors and other third parties; and

(cid:129) improving our operational, financial and management controls,  reporting systems  and

procedures.

Our future financial performance and  our  ability to commercialize our drug candidates  will

depend, in part, on our ability to effectively manage any future growth, and our management may  also
have to divert a disproportionate amount of its attention  away from day-to-day  activities in  order to
devote a substantial amount of time to  managing  these growth activities.

We  currently rely, and for the foreseeable future will continue to rely,  in substantial part  on certain

independent organizations, advisors and consultants  to  provide certain services. There can be no
assurance that the  services of these independent  organizations, advisors and consultants  will  continue to
be available to us on a timely basis when  needed, or that we can  find qualified replacements. In
addition, if we are unable to effectively manage our outsourced  activities or if the quality or accuracy of
the services provided by consultants is  compromised for  any reason, our clinical trials may  be  extended,
delayed or terminated, and we may not  be  able  to  obtain  regulatory approval of our drug candidates or
otherwise advance our business. There  can be no assurance  that we will be able to manage our existing
consultants or find other competent  outside contractors and  consultants on economically  reasonable
terms, if at all.

If we  are not able to effectively expand  our organization by  hiring new employees and expanding

our  groups of consultants and contractors, we may not be able  to  successfully  implement the tasks
necessary to further develop and commercialize  our drug  candidates and, accordingly,  may not achieve
our  research, development and commercialization goals.

Our employees, independent contractors, consultants,  commercial partners and  vendors may  engage in
misconduct or other improper activities, including  noncompliance  with regulatory standards and  requirements.

We  are exposed to the risk of fraud,  misconduct  or other illegal activity  by our  employees,
independent contractors, consultants, commercial  partners and vendors. Misconduct  by  these parties
could include intentional, reckless and negligent conduct that fails to: comply  with the laws of the  FDA
and other similar non-U.S. regulatory authorities; provide true, complete and  accurate  information to
the FDA and other similar non-U.S. regulatory authorities; comply with manufacturing  standards we
have established; comply with healthcare  fraud  and  abuse laws in  the United States  and similar
non-U.S.  fraudulent misconduct laws;  or report  financial information or data accurately or  to  disclose
unauthorized activities to us. If we obtain  FDA approval  of any of our  drug candidates and begin
commercializing those drugs in the United States,  our potential exposure under U.S.  laws  will  increase
significantly and our costs associated with compliance  with such  laws are also likely  to  increase. These
laws may impact, among other things,  our current  activities with  principal investigators and  research
patients, as well as future sales, marketing and education programs. In particular, the promotion, sales
and marketing of healthcare items and  services, as well  as certain business arrangements  in the

123

healthcare industry, are subject to extensive laws designed to prevent fraud,  kickbacks,  self-dealing  and
other abusive practices. These laws and regulations may  restrict or prohibit  a wide range of pricing,
discounting, marketing and promotion,  structuring and commission(s), certain customer incentive
programs and other business arrangements generally. Activities  subject to these laws also  involve  the
improper use of information obtained  in  the course of patient recruitment for clinical  trials, which
could result in regulatory sanctions and  cause serious harm  to  our reputation. It is  not  always possible
to identify and deter misconduct by employees and other parties, and the precautions we  take to detect
and prevent this activity may not be effective  in controlling unknown or unmanaged  risks  or losses or in
protecting us from governmental investigations  or other actions  or  lawsuits stemming from  a failure to
comply  with these laws or regulations. If  any  such actions are  instituted against  us, and  we are  not
successful in defending ourselves or asserting our rights,  those  actions could  have a significant impact
on our business, including the imposition  of  significant fines or other sanctions.

Our disclosure controls and procedures  may not prevent or  detect all  errors or acts  of fraud.

As a public company, we are subject  to the periodic reporting  requirements of  the Exchange Act.
Our disclosure controls and procedures  are designed to reasonably  assure that information  required to
be disclosed by us in reports we file or  submit under the Exchange  Act is accumulated and
communicated to management, and recorded, processed, summarized and reported within the time
periods specified in the rules and forms  of the SEC.  We believe that any  disclosure controls and
procedures or internal controls and procedures,  no matter how well conceived and operated,  can
provide only reasonable, not absolute,  assurance that the objectives of the  control system are  met.

These inherent limitations include the realities that  judgments in  decision-making can be faulty,

and that breakdowns can occur because of simple error or mistake.  Additionally,  controls can be
circumvented by the individual acts of  some persons,  by  collusion of two or  more people or  by  an
unauthorized override of the controls. Accordingly, because of the inherent  limitations in  our  control
system, misstatements due to error or fraud  may occur and  not be detected.

In order to satisfy our obligations as a public company, we will need to hire additional qualified accounting
and financial personnel with appropriate  public company  experience.

As a newly public company, we need  to establish and maintain effective disclosure and financial

controls and make changes in our corporate governance  practices.  We need to hire  additional
accounting and financial personnel with  appropriate public company experience and technical
accounting knowledge, and it may be difficult to recruit and maintain such personnel. Even  if we are
able to hire appropriate personnel, our  existing operating expenses and operations will be impacted by
the direct costs of their employment and  the indirect consequences related to the  diversion of
management resources from product  development  efforts.

If we engage in future acquisitions or strategic partnerships, this  may increase our capital requirements,  dilute
our shareholders, cause us to incur debt or  assume  contingent liabilities, and  subject us to other risks.

We  may evaluate various acquisitions and strategic partnerships, including licensing or  acquiring

complementary products, intellectual  property  rights, technologies  or businesses. Any potential
acquisition or strategic partnership may entail  numerous risks, including:

(cid:129) increased operating expenses and cash requirements;

(cid:129) the assumption of additional indebtedness or contingent liabilities;

(cid:129) the issuance of our equity securities;

(cid:129) assimilation of operations, intellectual property and  products  of  an acquired company, including

difficulties associated with integrating  new personnel;

124

(cid:129) the diversion of  our management’s attention from our existing  product  programs and  initiatives

in pursuing such a strategic merger or acquisition;

(cid:129) retention of key employees, the loss of  key  personnel, and uncertainties in our ability to

maintain key business relationships;

(cid:129) risks and uncertainties associated with the other  party  to such a transaction, including  the

prospects of that party and their existing drugs or  drug  candidates and regulatory  approvals;  and

(cid:129) our inability to generate revenue from  acquired  technology and/or  products sufficient  to  meet
our  objectives in undertaking the acquisition or even to offset  the associated  acquisition  and
maintenance costs.

In addition, if we undertake acquisitions, we may issue dilutive  securities, assume or incur debt

obligations, incur large one-time expenses  and acquire intangible  assets that could result in significant
future amortization expense. Moreover,  we  may not be able to locate suitable acquisition opportunities
and this inability could impair our ability to grow or  obtain access to technology or products that may
be important to the development of our business.

If we fail to comply with the U.S. Foreign  Corrupt  Practices  Act or  other anti-bribery laws,  our reputation
may be harmed and we could be subject to penalties and significant expenses that  have a material  adverse
effect on our business, financial condition and results  of operations.

Although currently our primary operating  business  is in China, we are subject  to  the Foreign
Corrupt Practices Act, or FCPA. The FCPA generally  prohibits  us from making  improper payments to
non-U.S.  officials for the purpose of obtaining or  retaining business. We are also subject to the
anti-bribery laws of other jurisdictions,  particularly China.  As our business has  expanded, the
applicability of the FCPA and other anti-bribery laws  to  our operations has increased. Our procedures
and controls to monitor anti-bribery  compliance  may fail to protect us from reckless  or criminal acts
committed by our  employees or agents.  If  we, due to either our  own deliberate or  inadvertent acts or
those of others, fail to comply with applicable anti-bribery laws, our reputation could be harmed and
we could incur criminal or civil penalties,  other  sanctions and/or significant  expenses, which could have
a material adverse effect on our business, including  our  financial condition, results of  operations, cash
flows and prospects.

Any failure to comply with applicable regulations  and industry standards or  obtain various licenses and
permits could harm our reputation and  our business,  results  of operations and prospects.

A number of governmental agencies or industry  regulatory bodies in  the United States,  and in
non-U.S.  jurisdictions including the PRC  and European Union,  impose strict rules, regulations  and
industry standards governing pharmaceutical and biotechnology research and development activities,
which  apply to us. Our failure to comply with such regulations could result  in the termination of
ongoing research,  administrative penalties  imposed by regulatory  bodies or  the disqualification  of data
for submission to regulatory authorities.  This could harm our  reputation, prospects for  future work and
operating results. For example, if we were to treat research animals inhumanely or  in violation  of
international standards set out by the  Association for Assessment and Accreditation of Laboratory
Animal Care, it could revoke any such accreditation  and the  accuracy of our animal research data
could be questioned.

125

If we or our CROs fail to comply with environmental, health and safety  laws and regulations, we could
become subject to fines or penalties or incur costs that could have a  material adverse  effect on  the success  of
our business.

We  and third parties, such as our CRO, are  subject to numerous environmental, health and safety

laws and regulations, including those governing laboratory  procedures  and  the handling, use, storage,
treatment and disposal of hazardous materials and wastes.  Our operations involve the  use of hazardous
and flammable materials, including chemicals and radioactive and biological materials. Our operations
also produce hazardous waste products. We generally contract with  third parties for  the disposal of
these materials and wastes. We also store certain low level radioactive waste  at our facilities until the
materials can be properly disposed of.  We  cannot eliminate  the risk of contamination or  injury  from
these materials. In the event of contamination or injury resulting from our use  of  hazardous  materials,
we could be held liable for any resulting  damages, and any  liability  could exceed our resources. We also
could incur significant costs associated with civil or criminal fines and  penalties.

Although we maintain workers’ compensation insurance to cover  us for costs and expenses  we may

incur due to injuries to our employees resulting from the use of or exposure to hazardous materials,
this  insurance may not provide adequate  coverage against potential liabilities. We  do not maintain
insurance for environmental liability or toxic tort claims  that may be asserted  against us in connection
with our storage, use or disposal of biological, hazardous or radioactive  materials.

In addition, we may be required to incur substantial costs  to comply  with current or future
environmental, health and safety laws  and  regulations.  These current or future laws and regulations
may impair our research, development  or production efforts.  Failure to comply with these laws and
regulations also may result in substantial  fines, penalties or other  sanctions.

If we face allegations of noncompliance  with the  law  and encounter  sanctions, our reputation, revenues  and
liquidity  may suffer, and our drugs could be  subject to restrictions or withdrawal from the  market.

Any government investigation of alleged  violations of law could  require  us to expend significant

time and resources in response, and could generate negative  publicity. Any failure  to  comply with
ongoing regulatory requirements may  significantly and adversely  affect our ability to commercialize and
generate revenues from our drugs. If  regulatory sanctions  are applied or if regulatory approval is
withdrawn, the value of our company and our operating results will be adversely affected. Additionally,
if we are unable to generate revenues  from our product  sales,  our potential for achieving profitability
will be diminished and the capital necessary to fund our operations will be increased.

Our internal computer systems, or those  used  by our CROs or other contractors or consultants,  may fail or
suffer security breaches.

Despite the implementation of security  measures, our internal computer systems and those of our

future CROs and other contractors and  consultants are vulnerable to damage  from computer viruses
and unauthorized access. Although to  our  knowledge  we have not experienced any such  material  system
failure or security breach to date, if such  an event were  to  occur  and cause interruptions in our
operations, it could result in a material disruption of our development programs and our business
operations. For example, the loss of clinical trial data  from completed  or  future clinical trials could
result in delays in our regulatory approval  efforts and significantly  increase our costs to recover  or
reproduce the data. Likewise, we partially  rely on our  third-party research institution collaborators for
research and development of our drug  candidates  and other third  parties for  the manufacture of our
drug candidates and to conduct clinical  trials, and  similar events relating to their computer systems
could also have a material adverse effect  on  our business. To  the  extent that any  disruption or security
breach were to result in a loss of, or damage  to,  our  data  or  applications, or inappropriate disclosure  of

126

confidential or proprietary information, we could incur liability and the further  development and
commercialization of our drug candidates could  be  delayed.

Business disruptions could seriously harm our future  revenue and  financial condition  and increase our  costs
and expenses.

Our operations, and those of our third-party research  institution collaborators, CROs, suppliers

and other contractors and consultants,  could  be  subject to earthquakes,  power  shortages,
telecommunications failures, water shortages, floods, hurricanes, typhoons, fires,  extreme weather
conditions, medical epidemics and other natural or man-made disasters or business interruptions, for
which  we are predominantly self-insured. In  addition, we partially rely on  our third-party research
institution collaborators for conducting research and development of  our drug candidates, and  they may
be affected by government shutdowns or  withdrawn  funding. The occurrence  of any  of  these  business
disruptions could seriously harm our operations and financial condition and increase our costs and
expenses. We partially rely on third-party manufacturers to  produce and  process  our  drug  candidates.
Our ability to obtain clinical supplies of  our drug candidates  could be disrupted  if the  operations  of
these suppliers are affected by a man-made  or natural disaster or other  business interruption. A  large
portion of our operations is located in  a  single facility in  Changping, Beijing,  PRC. Damage  or
extended periods of interruption to our corporate, development or research facilities due to fire,
natural disaster, power loss, communications failure, unauthorized entry  or other events could cause us
to cease or delay development of some  or all of our drug candidates.  Although we maintain property
damage  and business interruption insurance coverage on these facilities,  our  insurance might not cover
all losses  under such circumstances and  our business may be seriously  harmed by such delays  and
interruption.

If product liability lawsuits are brought against us, we may  incur substantial liabilities  and may  be  required
to limit commercialization of our drug  candidates.

We  face an inherent risk of product liability as a result of the clinical testing of  our drug

candidates and will face an even greater risk if  we commercialize any  drugs.  For example, we  may be
sued if  our drug candidates cause or  are  perceived to cause injury or are found to be otherwise
unsuitable during clinical testing, manufacturing, marketing or sale.  Any  such product liability claims
may include allegations of defects in manufacturing, defects in  design, a  failure to warn of  dangers
inherent in the drug, negligence, strict liability or  a breach of warranties.  Claims could also be asserted
under state consumer protection acts.  If  we cannot  successfully  defend ourselves  against product
liability claims, we may incur substantial liabilities  or be required  to  limit  commercialization of our drug
candidates. Even successful defense would require  significant financial and management resources.
Regardless of the merits or eventual  outcome, liability claims may result  in:

(cid:129) decreased demand for our drugs;

(cid:129) injury to our reputation;

(cid:129) withdrawal of clinical trial participants and inability to continue clinical trials;

(cid:129) initiation of investigations by regulators;

(cid:129) costs to defend the related litigation;

(cid:129) a diversion of management’s time and our resources;

(cid:129) substantial monetary awards to trial participants or patients;

(cid:129) product recalls, withdrawals or labeling, marketing or promotional restrictions;

(cid:129) loss of revenue;

127

(cid:129) exhaustion of any available insurance  and our capital  resources;

(cid:129) the inability to commercialize any  drug candidate; and

(cid:129) a decline in the ADS price.

Our inability to obtain sufficient product  liability  insurance at an acceptable cost  to  protect against

potential product liability claims could prevent or inhibit the commercialization  of drugs we  develop,
alone or with collaborators. Although  we  currently  hold  $10 million in product liability coverage in the
aggregate, the amount of such insurance  coverage  may not be adequate,  we may be unable to maintain
such insurance at a reasonable cost or  in  an amount adequate to satisfy  any  liability  that  may arise, or
we may not be able to obtain additional or replacement insurance at a reasonable cost,  if  at all. We
intend to expand our insurance coverage  for products  to  include the sale of commercial products if we
obtain marketing approval for our product  candidates in development,  but we  may be unable to obtain
commercially reasonable product liability insurance for any products approved for marketing. Our
insurance policies may also have various  exclusions, and  we may be subject to a product liability claim
for which we have no coverage. We may  have to pay any amounts awarded by a  court or  negotiated in
a settlement that exceed our coverage limitations or that are  not covered  by  our insurance, and  we may
not have, or be able to obtain, sufficient capital to pay such amounts.  Even if our agreements with any
future corporate collaborators entitle us  to indemnification against losses, such indemnification may not
be available or adequate should any claim arise.

We have  limited insurance coverage, and  any claims beyond our insurance coverage may result in  our
incurring substantial costs and a diversion of resources.

We  maintain property insurance policies covering  physical damage  to,  or loss of, our buildings  and

their improvements, equipment, office  furniture and inventory.  We hold employer’s liability insurance
generally covering death or work-related injury of employees. We hold  public liability insurance
covering certain incidents involving third  parties that occur  on or in the premises  of  the company. We
hold directors and officers liability insurance. We do not maintain key-man  life insurance on any  of our
senior management or key personnel,  or  business interruption  insurance. Our insurance coverage may
be insufficient to cover any claim for product liability, damage to our fixed assets or  employee injuries.
Any liability or damage to, or caused  by, our facilities or our  personnel beyond our insurance  coverage
may result in our incurring substantial  costs  and  a diversion  of  resources.

We may  market our drugs, if approved, globally, and we will be subject  to  the risks of doing business  outside
of the United States.

Because we intend to market drugs, if approved, globally, our business  is subject to risks associated

with doing business globally. Accordingly,  our business and  financial results  in the future could be
adversely affected due to a variety of factors,  including:

(cid:129) efforts to develop an international  sales, marketing and distribution  organization may increase
our  expenses, divert our management’s attention from the acquisition or development of drug
candidates or cause us to forgo profitable  licensing opportunities in these  geographies;

(cid:129) changes in a specific country’s or region’s political and cultural  climate or economic  condition;

(cid:129) unexpected changes in laws and regulatory requirements  in local jurisdictions;

(cid:129) difficulty of effective enforcement of  contractual  provisions in local jurisdictions;

(cid:129) inadequate intellectual property protection  in certain countries;

128

(cid:129) trade-protection measures, import  or export licensing requirements such as  Export

Administration Regulations promulgated by the  United States Department of Commerce and
fines, penalties or suspension or revocation of export  privileges;

(cid:129) the effects of applicable local tax regimes and potentially adverse  tax consequences; and

(cid:129) significant adverse changes in local  currency exchange rates.

Our business, financial condition and results of operations may be  adversely affected by  the downturn in the
global economy.

The global financial markets experienced  significant disruptions in 2008  and the  United States,
Europe and other  economies went into  recession. The  recovery from the  lows of 2008 and 2009  was
uneven  and it is facing new challenges,  including the  escalation of the European  sovereign  debt crisis
since 2011 and the United Kingdom’s decision to withdraw from the European Union. It  is unclear
whether the European sovereign debt crisis will be contained and  what  effects it and  the United
Kingdom’s decision to withdraw from the  European Union may have.  There is considerable uncertainty
over the long-term effects of the expansionary monetary and fiscal policies that have been adopted  by
the central banks and financial authorities of some of the world’s leading economies, including  China’s.
Economic conditions in United States  and China are sensitive to global economic conditions. Although
we are uncertain about the extent to which the  global financial market disruption  and slowdown of the
U.S. or Chinese economy may impact  our  business in  the long term, there is  a risk  that  our  business,
results of operations and prospects would be materially  and  adversely affected by the  global economic
downturn and the slowdown of the U.S. or  Chinese  economy.

Recent developments relating to the United  Kingdom’s referendum vote in  favor of withdrawal from the
European Union could adversely affect  us.

The United Kingdom held a referendum on  June  23, 2016 in  which a majority voted for the
United Kingdom’s  withdrawal from the European  Union (referred to as ‘‘Brexit’’).  As a  result of this
vote, negotiations are expected to commence to determine the terms  of the United Kingdom’s
withdrawal from the European Union as  well  as its relationship with the European Union  going
forward, including the terms of trade  between the  United Kingdom and the European Union. The
effects of Brexit have been and are expected to continue to be far-reaching. Brexit and the perceptions
as to its impact may adversely affect  business activity and economic conditions in Europe and globally
and could continue to contribute to instability in  global financial and foreign exchange markets. Brexit
could also have the effect of disrupting  the free movement  of goods, services and people  between  the
United Kingdom and the European Union; however, the full effects  of Brexit  are uncertain  and will
depend  on any agreements the United Kingdom may make to retain access  to  European Union
markets.

In addition, we expect that Brexit could  lead to legal uncertainty and  potentially divergent  national

laws and regulations as the United Kingdom determines which  European Union laws to replicate or
replace. If the United Kingdom were to significantly alter its  regulations  affecting the pharmaceutical
industry, we could face significant new  costs. It may also be time-consuming and expensive for us to
alter our internal operations in order to comply  with new  regulations. Altered regulations could also
add time and expense to the process  by which  our  product candidates  receive regulatory  approval in
the United Kingdom and European Union. Similarly,  it is  unclear at this  time what  Brexit’s  impact  will
have on our intellectual property rights and the process  for  obtaining,  maintaining  and defending such
rights. It is possible that certain intellectual  property rights,  such as trademarks, granted by the
European Union will cease being enforceable in the United Kingdom absent  special arrangements  to
the contrary, and we are required to  refile our trademarks and other intellectual property applications
domestically in the United Kingdom.  With regard to existing patent rights, the effect of  Brexit should

129

be minimal considering enforceable patent rights  are specific to the United Kingdom,  whether  arising
out of the European Patent Office or directly through the  United Kingdom patent office.

Lastly, as a result of Brexit, other European  countries may seek to conduct referenda with  respect

to their continuing membership in the  European Union. Given these possibilities and  others we  may
not anticipate, as well as the lack of comparable precedent, the full extent to which our business,
results of operations and financial condition could be adversely affected  by Brexit is  uncertain.

We manufacture and intend to continue to manufacture at least a portion of our drug candidates ourselves.
Delays  in completing and receiving regulatory  approvals  for our manufacturing facility  could delay our
development plans and thereby limit our revenues and growth.

We  currently lease an approximately  140 square  meter manufacturing  facility  in Beijing,  PRC,
which  produces and supplies preclinical and clinical trial  materials  for  some of our small molecule  drug
candidates. In addition, to increase our manufacturing capabilities, we lease an  approximately 11,000
square  meter space and are building a  manufacturing facility in  Suzhou,  China, where we intend  to
produce drug candidates for clinical  or, in the future, commercial use. This facility  consists of  one
oral-solid-dosage production line for  small molecule drug products and  one  pilot plant for  monoclonal
antibody  drug substances. This new manufacturing facility  is expected to be completed  in 2017. This
project may encounter unanticipated  delays and cost  more than  expected due to a  number of factors,
including regulatory requirements. If  construction or regulatory approval of  our  new facility is  delayed,
we may not be able to manufacture sufficient quantities  of  our drug candidates, which would limit our
development activities and our opportunities for  growth. Suzhou Industrial Park  Biotech
Development Co., Ltd. and China Construction Bank have agreed to lend  us  RMB 120 million for the
construction of the Suzhou manufacturing facility and the procurement of equipment.  Cost overruns
associated with constructing our Suzhou  facility could require us to raise additional  funds  from other
sources.

In addition to the similar manufacturing risks described in ‘‘—Risks Related to Our Reliance  on

Third Parties,’’ our manufacturing facilities will  be  subject to ongoing, periodic inspection by the  FDA,
CFDA, EMA or other comparable regulatory agencies to ensure compliance with cGMP. Our  failure to
follow and document our adherence to  such  cGMP regulations  or other  regulatory requirements may
lead to significant delays in the availability of products for clinical or, in the  future, commercial use,
may result in the termination of or a hold  on  a clinical  trial, or may delay or prevent  filing or  approval
of marketing applications for our drugs. We also may encounter  problems  with the following:

(cid:129) achieving adequate or clinical-grade materials that  meet  FDA, CFDA, EMA or other

comparable regulatory agency standards or specifications  with consistent  and acceptable
production yield and costs;

(cid:129) shortages of qualified personnel, raw materials or key contractors; and

(cid:129) ongoing compliance with cGMP regulations and  other requirements of the FDA, CFDA, EMA

or other comparable regulatory agencies.

Failure to comply with applicable regulations could also result in sanctions being imposed  on us,
including fines, injunctions, civil penalties,  a  requirement to suspend or put on  hold  one  or more of our
clinical trials, failure of regulatory authorities to grant  marketing  approval of our drug candidates,
delays, suspension or withdrawal of approvals, license revocation, seizures or  recalls of drug  candidates,
operating restrictions and criminal prosecutions,  any of which could harm  our business.

Developing advanced manufacturing techniques  and process controls is  required  to  fully utilize our
facilities. Advances in manufacturing  techniques may render our facilities and equipment inadequate or
obsolete.

130

To produce our drugs in the quantities  that  we believe will be required  to  meet anticipated  market

demand of any of our drug candidates if approved, we  will need to increase, or ‘‘scale up,’’ the
production process by a significant factor over the  initial level of production. If we are unable  to  do  so,
are delayed, or if the cost of this scale up is not economically feasible for us or  we cannot  find a third-
party supplier, we may not be able to  produce our drugs in a sufficient  quantity  to  meet future
demand.

If our manufacturing facilities, including our Suzhou manufacturing facility once completed, are damaged  or
destroyed or production at such facilities is otherwise  interrupted,  our  business and prospects would be
negatively affected.

In addition to the similar manufacturing risks described in ‘‘—Risks Related to Our Reliance  on
Third Parties,’’ if our manufacturing facilities or the equipment in them is damaged or destroyed,  we
may not be able to quickly or inexpensively  replace our manufacturing capacity  or replace  it at all. In
the event of a temporary or protracted  loss of the  facilities or equipment, we might not be able to
transfer manufacturing to a third party.  Even  if we could transfer manufacturing to a  third  party, the
shift  would likely be expensive and time-consuming, particularly since the new facility would need to
comply  with the necessary regulatory requirements and we  would need FDA, CFDA, EMA or and
other comparable  regulatory agency approval  before  selling any drugs manufactured at  that  facility.
Such an event could delay our clinical trials  or reduce  our product sales if  and when we  are able to
successfully commercialize one or more  of  our  drug candidates.

Any interruption in manufacturing operations at our manufacturing facilities could result  in our
inability to satisfy the demands of our clinical trials  or commercialization. A number  of  factors could
cause  interruptions, including:

(cid:129) equipment malfunctions or failures;

(cid:129) technology malfunctions;

(cid:129) work stoppages;

(cid:129) damage to or destruction of either facility due to natural disasters;

(cid:129) regional power shortages;

(cid:129) product tampering; or

(cid:129) terrorist activities.

Any disruption that impedes our ability to manufacture our drug candidates in a  timely  manner

could materially harm our business, financial condition  and  operating results.

Currently, we maintain insurance coverage against damage to our  property and  equipment in the
amount of up to RMB 100 million. However, our insurance  coverage may not reimburse us, or may  not
be sufficient to reimburse us, for any expenses  or losses we may suffer. We may be unable  to  meet our
requirements for our drug candidates  if there were a catastrophic  event or failure  of  our  manufacturing
facilities or processes.

Risks Related to Our Doing Business in the  PRC

The pharmaceutical industry in China  is  highly regulated and such  regulations  are subject to  change which
may affect approval and commercialization  of our drugs.

Our research operations and manufacturing facilities are in China,  which we believe confers

clinical, commercial and regulatory advantages. The pharmaceutical  industry in China  is subject to
comprehensive government regulation  and  supervision, encompassing  the approval, registration,

131

manufacturing, packaging, licensing and  marketing of  new drugs. See ‘‘Item 1—Business—Regulatory
Framework and Structural Advantages of  Being a China-Based Research and Development
Organization’’ for a discussion of regulatory requirements that are applicable  to  our current and
planned business activities in China. In recent  years,  the regulatory  framework in China  regarding the
pharmaceutical industry has undergone significant changes,  and we expect  that  it will continue  to
undergo significant changes. Any such  changes or  amendments may result in increased  compliance costs
on our business or cause delays in or  prevent the successful development or commercialization of our
drug candidates in China and reduce  the current  benefits we believe are  available  to  us  from
developing and manufacturing drugs  in China. Chinese authorities have become increasingly vigilant in
enforcing laws in the pharmaceutical industry and  any  failure by us or  our partners to maintain
compliance with applicable laws and regulations or obtain and maintain required licenses and permits
may result in the suspension or termination of our business activities in China.  We believe our strategy
and approach is aligned with the Chinese  government’s policies, but we cannot ensure that our strategy
and approach will continue to be aligned.

Changes in the political and economic  policies of  the  PRC government  may materially and adversely affect
our business, financial condition and results  of operations and may  result in  our inability  to sustain  our
growth and expansion strategies.

A significant portion of our operations  are in the  PRC. Accordingly,  our financial condition and
results of operations are affected to a  large extent by economic, political and legal developments in  the
PRC.

The PRC economy differs from the economies of most  developed  countries in many respects,
including the extent of government involvement, level of development,  growth rate,  control of foreign
exchange and allocation of resources. Although the  PRC government has implemented measures
emphasizing the utilization of market  forces for  economic  reform,  the reduction of state  ownership  of
productive assets, and the establishment of improved corporate governance in business enterprises, a
substantial portion of productive assets in  China is still owned by  the government.  In addition, the  PRC
government continues to play a significant role in regulating industry development by imposing
industrial policies. The PRC government  also  exercises  significant control  over China’s  economic
growth by allocating resources, controlling payment of foreign currency-denominated obligations, setting
monetary policy, regulating financial services and  institutions  and providing preferential treatment  to
particular industries or companies.

While the PRC economy has experienced  significant growth in the  past three decades, growth has

been uneven, both geographically and  among various sectors of  the economy.  The PRC government has
implemented various measures to encourage  economic growth  and guide the  allocation of resources.
Some of these measures may benefit the overall PRC economy, but  may also have  a negative effect on
us. Our financial condition and results of operation could be  materially and adversely affected by
government control over capital investments  or changes in  tax  regulations that are  applicable to us  and
consequently have a material adverse  effect on  our  businesses,  financial condition and results  of
operations.

There are uncertainties regarding the interpretation and  enforcement  of PRC laws, rules and regulations.

A large portion of our operations are conducted in  the PRC through  our PRC  subsidiaries,  and
are governed by PRC laws, rules and  regulations. Our PRC subsidiaries  are subject to laws, rules  and
regulations applicable to foreign investment  in China. The PRC legal  system is a  civil law  system based
on written statutes. Unlike the common  law system, prior  court decisions may be cited for  reference
but have limited precedential value.

132

In 1979, the PRC government began to promulgate  a comprehensive  system of laws, rules and
regulations governing economic matters  in  general. The  overall effect  of legislation over  the past three
decades has significantly enhanced the  protections afforded to various forms  of  foreign investment in
China. However, China has not developed  a fully integrated  legal system,  and recently  enacted laws,
rules and regulations may not sufficiently  cover all aspects of  economic activities  in China  or may be
subject to significant degrees of interpretation  by  PRC regulatory agencies. In particular, because these
laws, rules and regulations are relatively new, and because of the limited number of published  decisions
and the nonbinding nature of such decisions, and because the laws, rules  and regulations often give the
relevant regulator  significant discretion in how to enforce  them, the  interpretation and  enforcement of
these laws, rules and regulations involve  uncertainties and  can be inconsistent and  unpredictable. In
addition, the PRC legal system is based  in  part on  government policies and internal  rules, some  of
which  are not published on a timely basis or at all, and which may  have a retroactive effect.  As a
result, we may not be aware of our violation of these policies and rules  until after the  occurrence of
the violation.

Any administrative and court proceedings in China may be protracted, resulting in substantial costs

and diversion of resources and management attention. Since PRC administrative  and court authorities
have significant discretion in interpreting and implementing statutory  and contractual terms, it  may be
more difficult to evaluate the outcome  of administrative and court  proceedings and the level of legal
protection we enjoy than in more developed legal systems.  These uncertainties may  impede  our ability
to enforce the contracts we have entered  into  and could materially and adversely affect our business,
financial condition and results of operations.

Substantial uncertainties exist with respect  to the enactment timetable, the final version, interpretation and
implementation of draft PRC Foreign Investment Law and how  it may impact the  viability  of our current
corporate governance.

The Ministry of Commerce published a discussion draft  of  the proposed Foreign Investment Law

in January 2015 aiming to, upon its enactment, replace the trio  of existing  laws  regulating foreign
investment in China, namely, the Sino-foreign Equity  Joint Venture Enterprise Law, the  Sino-foreign
Cooperative Joint Venture Enterprise  Law and the Wholly Foreign-invested  Enterprise Law, together
with their implementation rules and ancillary regulations. The draft Foreign Investment Law embodies
an expected PRC regulatory trend to rationalize  its foreign  investment regulatory  regime in line with
prevailing international practice and the legislative efforts  to unify the corporate legal requirements for
both foreign and domestic investments.  The Ministry  of  Commerce has solicited  comments  on this draft
and substantial uncertainties exist with  respect to its enactment timetable,  the final version,
interpretation and implementation. The  draft Foreign Investment Law,  if enacted as proposed, may
materially impact the viability of our  current  corporate  governance if we, in the future,  have PRC
shareholders.

Among other things, the draft Foreign Investment Law expands the  definition of foreign
investment and introduces the principle of ‘‘actual control’’  in determining whether a  company is
considered a foreign-invested enterprise, or  an FIE. The draft  Foreign Investment Law specifically
provides that entities established in China but ‘‘controlled’’ by  foreign investors  will  be  treated  as FIEs,
whereas an entity set up in a foreign jurisdiction would nonetheless be, upon  market  entry clearance  by
the Ministry of Commerce or its local  counterparts, treated as  a  PRC domestic  investor provided that
the entity is ‘‘controlled’’ by PRC entities  and/or citizens. In this connection,  ‘‘control’’ is broadly
defined in the draft law to cover the  following  summarized  categories: (1) holding 50% of more  of the
shares, equity or voting rights of the  subject entity; (2) holding less than 50% of the  voting rights  of  the
subject entity but having the power to secure at  least 50% of  the  seats on  the board  or other equivalent
decision making bodies, or having the voting power to exert  material influence  on the board, the
shareholders’ meeting or other equivalent  decision  making bodies; or  (3) having the power to exert

133

decisive influence, via contractual or  trust  arrangements, over the subject  entity’s operations, financial
matters or other key aspects of business  operations. Once an entity  is determined  to  be  an FIE, it  will
be subject to the foreign investment  restrictions  or prohibitions, if  the FIE is engaged in the  industry
listed in the ‘‘negative list’’ which will be separately  issued by  the Chinese  State  Council  later. Unless
the underlying business of the FIE falls within  the negative list, which calls for  market entry clearance
by the Ministry of Commerce or its local  counterparts, prior approval from the government authorities
as mandated by the existing foreign investment legal  regime would  no longer  be  required for
establishment of the FIE.

The draft Foreign Investment Law, if  enacted as proposed, may also materially  impact  our

corporate governance practice and increase our compliance costs. For instance, the draft Foreign
Investment Law imposes stringent ad  hoc  and periodic information reporting requirements on foreign
investors and the applicable FIEs. Aside from investment  implementation report and investment
amendment report that are required  at each investment and alteration  of  investment specifics, an
annual report is mandatory, and large  foreign investors meeting  certain criteria  are required  to  report
on a quarterly basis. Any company found to be non-compliant with these information  reporting
obligations may potentially be subject to fines  and/or administrative or criminal liabilities, and  the
persons directly responsible may be subject  to  criminal liabilities.

PRC regulations relating to investments  in  offshore companies  by PRC residents may subject our future
PRC-resident beneficial owners or our  PRC  subsidiaries to liability or  penalties,  limit our ability to  inject
capital into our PRC subsidiaries or limit  our PRC subsidiaries’ ability to increase their  registered  capital or
distribute profits.

SAFE promulgated the Circular on Relevant Issues Concerning Foreign  Exchange Control on

Domestic Residents’ Offshore Investment and  Financing  and  Roundtrip Investment through Special
Purpose Vehicles, or SAFE Circular  37, on July  4, 2014,  which replaced the former circular  commonly
known as ‘‘SAFE Circular 75’’ promulgated  by  SAFE on October  21, 2005. SAFE Circular 37  requires
PRC residents to register with local branches of SAFE in  connection with their  direct establishment or
indirect control of an offshore entity,  for  the purpose of overseas investment  and financing, with such
PRC residents’ legally owned assets or  equity  interests  in domestic enterprises or offshore assets or
interests, referred to in SAFE Circular  37 as a ‘‘special  purpose vehicle.’’ SAFE  Circular 37 further
requires amendment to the registration  in the event  of  any significant changes with respect to the
special purpose vehicle, such as increase  or decrease  of capital contributed by PRC individuals, share
transfer or exchange, merger, division or  other  material event. In the event that a  PRC shareholder
holding interests in a special purpose vehicle  fails to fulfill the required SAFE registration, the PRC
subsidiaries of that special purpose vehicle may be prohibited  from  making profit distributions to the
offshore parent and from carrying out  subsequent  cross-border foreign exchange activities,  and the
special purpose vehicle may be restricted in  its  ability to contribute  additional capital into its PRC
subsidiary. Moreover, failure to comply  with  the various SAFE registration requirements  described
above could result in liability under PRC  law  for evasion of  foreign exchange  controls.

We  believe that four of our shareholders, each of whom owns  our ordinary shares  as a result of

exercising share options, are PRC residents under  SAFE Circular  37. These four shareholders have
undertaken to (i) apply to register with local  SAFE  branch or its delegated commercial  bank  as soon as
possible after exercising their options,  and (ii)  indemnify  and  hold  harmless us  and our subsidiaries
against any loss suffered arising from  their  failure to complete the registration.  We do not have control
over the four shareholders and our other beneficial owners and cannot assure  you that all of our
PRC-resident beneficial owners have complied  with, and will in the  future comply  with, SAFE
Circular 37 and subsequent implementation  rules.  The failure  of  PRC-resident beneficial owners  to
register or amend their SAFE registrations in  a timely manner pursuant to SAFE Circular 37  and
subsequent implementation rules, or the  failure  of future  PRC-resident beneficial  owners of our

134

company to comply with the registration procedures set  forth in SAFE Circular 37 and subsequent
implementation rules, may subject such beneficial  owners or our  PRC subsidiaries  to  fines and legal
sanctions. Furthermore, SAFE Circular  37  is  unclear how this regulation, and  any future regulation
concerning offshore or cross-border transactions,  will  be  interpreted,  amended and implemented by the
relevant PRC government authorities, and  we cannot predict how these  regulations  will affect our
business operations or future strategy.  Failure  to  register  or comply with relevant requirements may
also limit our ability to contribute additional capital to our  PRC subsidiaries and limit our PRC
subsidiaries’ ability to distribute dividends  to us. These risks could  in the future have a material adverse
effect on our business, financial condition  and  results of operations.

Any failure to comply with PRC regulations  regarding our  employee equity  incentive  plans  may subject the
PRC plan participants or us to fines and  other legal or administrative  sanctions.

We  and our directors, executive officers and other employees who  are PRC residents have

participated in our employee equity incentive plans. Upon completion of our initial public offering, we
became an overseas listed company. Pursuant  to  SAFE  Circular 37, PRC residents  who participate in
share incentive plans in overseas non-publicly-listed companies may submit applications to SAFE or  its
local branches for the foreign exchange  registration with  respect  to  offshore special  purpose companies.
Our directors, executive officers and  other  employees who are PRC citizens or who  have resided in the
PRC for a continuous period of not  less than one year and who have been granted  restricted shares  or
options may follow SAFE Circular 37  to  apply  for the  foreign exchange registration before our
company became an overseas listed company. However, in practice,  different local SAFE branches may
have different views and procedures on  the application and implementation of SAFE regulations, and
there remains uncertainty with respect  to  its  implementation. If we or our  directors, executive officers
or other  employees who are PRC citizens or who have resided in the PRC for a continuous period of
not less than one year and who have  been  granted restricted shares  or options, including but not
limited to the four shareholders referred to above,  fail to register the employee equity  incentive plans
or their exercise of options, we and such  employees may be subject to (i)  legal or administrative
sanctions imposed by the SAFE or other  PRC authorities, including fines; (ii)  to  restrictions on our
cross-border investment activities; (iii) to limits on  the ability of our wholly owned subsidiaries in  China
to distribute dividends or the proceeds from  any  reduction in  capital,  share transfer or  liquidation to
us; and (iv) to prohibitions on our ability  to  inject additional  capital into these subsidiaries. Moreover,
failure to comply with the various foreign  exchange registration requirements described  above could
result in liability under PRC law for  circumventing  applicable foreign exchange  restrictions. As a result,
our  business operations and our ability  to  distribute profits  to  you could be materially  and adversely
affected. Upon completion of our initial  public offering, we became an overseas listed  company, and
therefore, we and our directors, executive  officers  and other employees who are PRC citizens  or who
have resided in the PRC for a continuous  period of not less than one year and  who have been  granted
restricted shares or options are subject  to  the Notice on  Issues Concerning  the Foreign Exchange
Administration for Domestic Individuals  Participating  in Stock Incentive Plan of  Overseas Publicly
Listed Company, issued by SAFE in February 2012, according to which, employees, directors,
supervisors and other management members  participating  in any  share incentive plan  of an overseas
publicly listed company who are PRC citizens  or who  are non-PRC  citizens residing in China  for a
continuous period of not less than one  year,  subject to limited  exceptions, are required to register with
SAFE through a domestic qualified agent,  which  could be a PRC subsidiary of such  overseas  listed
company, and complete certain other procedures. Failure to complete the  SAFE  registrations may
subject them to fines and legal sanctions and may also  limit our  ability  to  make  payments under our
equity incentive plans or receive dividends or sales proceeds related thereto,  or our  ability to contribute
additional capital into our wholly-foreign owned enterprises in China  and  limit our  wholly-foreign
owned enterprises’ ability to distribute  dividends to us. We also face regulatory uncertainties  that  could

135

restrict our ability to adopt additional equity incentive plans  for our directors and  employees under
PRC law.

In addition, the SAT has issued circulars concerning  employee share  options or  restricted shares.
Under these circulars, employees working  in the PRC  who exercise share options,  or whose restricted
shares vest, will be subject to PRC individual  income  tax. The PRC subsidiaries of an overseas listed
company have obligations to file documents  related to employee share options or restricted  shares with
relevant tax authorities and to withhold individual  income taxes  of those employees related to their
share options or restricted shares. If the  employees  fail to pay, or the PRC subsidiaries fail  to  withhold
applicable income taxes, the PRC subsidiaries  may face  sanctions imposed  by  the tax  authorities or
other PRC government authorities.

In the future, we may rely to some extent on  dividends and  other distributions on equity from our principal
operating subsidiaries to fund offshore  cash  and financing  requirements.

We  are a holding company, incorporated  in the Cayman Islands, and  may in the  future rely to
some extent on dividends and other  distributions on equity  from  our principal operating subsidiaries for
our  offshore cash and financing requirements,  including the  funds  necessary  to  pay dividends and  other
cash distributions to our shareholders,  fund inter-company loans,  service any debt we  may incur outside
China and pay our expenses. The laws,  rules and regulations  applicable to our  PRC subsidiaries and
certain other subsidiaries permit payments  of  dividends  only out of their retained earnings,  if any,
determined in accordance with applicable accounting standards and  regulations.

Under PRC laws, rules and regulations, each of our  subsidiaries incorporated  in China is required

to set aside a portion of its net income  each year  to  fund  certain statutory  reserves. These reserves,
together with the registered equity, are  not  distributable as cash dividends. As a result  of  these  laws,
rules and regulations, our subsidiaries incorporated in  China are restricted in their  ability to transfer a
portion of their respective net assets  to their shareholders as dividends. In  addition,  registered  share
capital and capital reserve accounts are  also restricted  from  withdrawal in  the PRC, up to the amount
of net assets held in each operating subsidiary.  As of  December 31,  2016, these restricted assets totaled
RMB69.1 million ($10.0 million).

The Enterprise Income Tax Law, or  the EIT Law and its implementation  rules, both of which
became effective on January 1, 2008, provide that China-sourced income of foreign enterprises, such as
dividends paid by a PRC subsidiary to its  equity holders that  are  non-PRC resident enterprises,  will
normally be subject to PRC withholding tax at a rate of 10%, unless any such foreign  investor’s
jurisdiction of incorporation has a tax  treaty with  China that provides for  a different withholding
arrangement. As a result, dividends paid  to  us  by  our PRC subsidiaries  are expected to be subject to
PRC withholding tax at a rate of 10%.

Pursuant to the Arrangement between Mainland  China and  Hong Kong Special Administrative

Region for the Avoidance of Double Taxation  and Prevention of Fiscal Evasion with respect to Taxes
on Income, or the ‘‘Hong Kong Tax Treaty,’’ BeiGene (Hong  Kong) Co.,  Limited, the  shareholder of
our  PRC subsidiaries, may be subject  to  a  withholding tax at  a rate  of 5% on dividends received from
our  PRC operating subsidiaries as a Hong Kong tax resident. Pursuant to the  Hong  Kong Tax Treaty,
subject to certain conditions, this reduced withholding  tax rate will be available for dividends from PRC
entities provided that the recipient can demonstrate it is a  Hong Kong tax resident and  it is the
beneficial owner of the dividends. BeiGene  (Hong Kong) Co., Limited currently does  not  hold  a Hong
Kong tax resident certificate from the Inland Revenue  Department  of  Hong Kong  and there  is no
assurance that the  reduced withholding  tax rate will be available.

Furthermore, if our subsidiaries in China  incur debt on their own behalf in the future, the
instruments governing the debt may restrict their ability  to pay  dividends  or make  other payments  to
us. Any limitation on the ability of our subsidiaries  to  distribute dividends or other payments to us in

136

the future could materially and adversely limit our ability to make investments or  acquisitions that
could be beneficial to our businesses,  pay dividends, or otherwise fund and conduct our business.

We may  be treated as a resident enterprise  for PRC tax purposes  under  the  EIT Law and be subject to  PRC
tax on our worldwide taxable income at a rate of 25%.

Under the EIT Law an enterprise established outside China with ‘‘de  facto management bodies’’
within China  is considered a ‘‘resident  enterprise,’’  meaning that it is treated in a manner similar to a
Chinese enterprise for PRC enterprise  income tax, or EIT, purposes. The implementing  rules  of the
EIT Law define ‘‘de facto management  bodies’’ as ‘‘management bodies that exercise substantial and
overall management and control over  the production  and  operations,  personnel, accounting, and
properties’’ of the enterprise. In addition, the  Notice  Regarding the Determination of Chinese-
Controlled Offshore Incorporated Enterprises as  PRC Tax Resident Enterprises on  the Basis of De
Facto Management Bodies, or Circular 82,  specifies that  certain Chinese-controlled offshore
incorporated enterprises, defined as enterprises incorporated under  the laws of foreign countries  or
territories and that have PRC enterprises or enterprise groups as their primary  controlling  shareholders,
will be classified as resident enterprises  if  all of the  following  are located or  resident  in
China: (i) senior management personnel and departments  that  are  responsible for daily production,
operation and management; (ii) financial and personnel  decision-making bodies;  (iii) key properties,
accounting books, company seal, and minutes of board meetings and shareholders’ meetings; and
(iv) half or more of senior management or directors having voting  rights.  On July 27,  2011, the SAT
issued Administrative Measures of Enterprise  Income Tax of Chinese-Controlled  Offshore Incorporated
Resident Enterprises (Trial), or Bulletin 45,  which became  effective  on  September 1, 2011  and was  most
recently amended on October 1, 2016,  to  provide further guidance on  the implementation of
Circular 82. Bulletin 45 clarifies certain issues related  to  determining PRC resident enterprise status,
including which competent tax authorities are responsible for  determining offshore incorporated  PRC
resident  enterprise status, as well as post-determination  administration.  In 2014, the SAT, released the
Announcement of the SAT on Issues Concerning the Recognition of Chinese-Controlled Enterprises
Incorporated Overseas as Resident Enterprises  on the Basis of Their Actual Management Bodies and
supplemented some provisions on the  administrative procedures  for the  recognition of resident
enterprise, while the standards used to classify resident  enterprises in Circular 82 remain unchanged.

Although BeiGene, Ltd. does not have a  PRC  enterprise  or enterprise group  as our primary
controlling shareholder and is therefore  not  a Chinese-controlled offshore  incorporated enterprise
within the meaning of Circular 82, in the  absence of guidance specifically applicable to us, we have
applied  the guidance set forth in Circular 82  to  evaluate the  tax residence status of BeiGene,  Ltd. and
its  subsidiaries organized outside the  PRC.

We  are not aware of any offshore holding company with a corporate structure  similar to ours that

has been deemed a PRC ‘‘resident enterprise’’ by the  PRC tax authorities.  Accordingly, we do not
believe our company or any of our overseas subsidiaries  should be treated as  a PRC resident
enterprise.

If the PRC tax authorities determine that our Cayman Islands  holding  company is  a resident
enterprise for PRC EIT purposes, a number  of unfavorable  PRC tax  consequences could follow and we
may be subject to EIT at a rate of 25% on our worldwide  taxable income,  as well as to PRC EIT
reporting obligations. In that case, it is  possible that  dividends paid to us  by  our PRC subsidiaries will
not be subject to PRC withholding tax.

137

Dividends payable to our foreign investors  may be subject to PRC withholding tax and gains on  the sale of  the
ADSs or ordinary shares by our foreign  investors may be subject to PRC tax.

If we  are deemed a PRC resident enterprise as described under  ‘‘—We may be treated as a
resident  enterprise for PRC tax purposes  under  the EIT Law and be subject to PRC tax on  our
worldwide taxable income at a rate of 25%,’’ dividends paid on our  ordinary  shares or  ADSs, and  any
gain realized from the transfer of our ordinary shares or  ADSs,  may be treated as  income  derived from
sources  within the PRC. As a result, dividends paid to non-PRC resident enterprise ADS holders  or
shareholders may be subject to PRC withholding  tax  at a  rate  of  10%  (or 20% in  the case of non-PRC
individual ADS holders or shareholders)  and  gains realized by non-PRC resident enterprises ADS
holders  or shareholders from the transfer of  our  ordinary shares or ADSs  may be subject to PRC tax  at
a rate of 10% (or 20% in the case of non-PRC  individual ADS holders or shareholders). It is  unclear
whether if we or any of our subsidiaries established outside China  are  considered  a PRC resident
enterprise, holders of the ADSs or ordinary shares would be able to claim the benefit of  income  tax
treaties or agreements entered into between China and other countries or areas.  If dividends payable to
our  non-PRC investors, or gains from the  transfer of the  ADSs or ordinary shares  by  such investors are
subject to PRC tax, the value of your  investment in the  ADSs or ordinary shares may decline
significantly.

We and our shareholders face uncertainties with  respect to indirect transfers of equity interests  in  PRC
resident enterprises or other assets attributed to a PRC establishment of a  non-PRC  company, or other assets
attributable to a PRC establishment of a  non-PRC company.

On February 3, 2015, the SAT issued the Bulletin  on Issues of  Enterprise Income Tax  and Indirect

Transfers of Assets by Non-PRC Resident  Enterprises, or  Bulletin 7,  which replaced or  supplemented
certain previous rules under the Notice on Strengthening Administration of  Enterprise Income  Tax for
Share Transfers by Non-PRC Resident  Enterprises, or Circular 698, issued  by  the SAT, on
December 10, 2009. Pursuant to this  Bulletin, an ‘‘indirect transfer’’ of ‘‘PRC taxable  assets,’’ including
equity interests in a PRC resident enterprise, by non-PRC resident enterprises may be recharacterized
and treated as a direct transfer of PRC  taxable assets, if  such arrangement  does not have  a reasonable
commercial purpose and was established for the  purpose of avoiding  payment of PRC enterprise
income tax. As a result, gains derived from such indirect transfer  may  be  subject to PRC enterprise
income tax. When determining whether  there  is a  ‘‘reasonable commercial purpose’’ of  the transaction
arrangement, factors to be taken into consideration include:  whether  the main value  of the equity
interest of the relevant offshore enterprise derives from  PRC taxable  assets; whether the  assets of the
relevant offshore enterprise mainly consists  of  direct or  indirect  investment in China or if its income
mainly derives from China; whether  the offshore enterprise and its subsidiaries directly or indirectly
holding PRC taxable assets have real  commercial nature which is  evidenced  by  their  actual function and
risk exposure; the duration of existence  of  the business model and organizational structure; the
replicability of the transaction by direct  transfer of  PRC taxable assets; and the tax situation of such
indirect transfer and applicable tax treaties or similar arrangements.  In respect of an  indirect offshore
transfer of assets of a PRC establishment, the resulting  gain is  to  be  reported  on with the enterprise
income tax filing of the PRC establishment  or place  of  business  being  transferred, and would
consequently be subject to PRC enterprise income tax at  a rate of 25%. Where  the underlying transfer
relates to equity investments in a PRC  resident enterprise, which is  not related to a PRC  establishment
or place of business of a non-resident  enterprise, a  PRC enterprise income tax at the  rate of  10%
would apply, subject to available preferential tax treatment  under applicable tax treaties  or similar
arrangements. Late payment of applicable  tax will subject the transferor  to  default interest. Gains
derived from the sale of shares by investors through  a public stock exchange are not subject  to  the PRC
enterprise income tax pursuant to Bulletin 7  where such shares were acquired in a transaction through
a public  stock exchange. As such, the  sale of the ADSs or ordinary shares on a public stock exchange
will not be subject to PRC enterprise income tax pursuant to Bulletin  7. However, the sale of our

138

ordinary shares or ADSs by a non-PRC resident enterprise outside  a  public  stock exchange  may be
subject to PRC enterprise income tax  under Bulletin 7.

There are uncertainties as to the application of Bulletin 7. Bulletin  7 may be determined  by  the  tax
authorities to be applicable to sale of the shares of our  offshore subsidiaries or investments  where PRC
taxable assets are involved. The transferors and transferees  may  be  subject to the  tax filing and
withholding or tax payment obligation,  while our PRC subsidiaries may  be  requested to assist in the
filing. Furthermore, we, our non-resident enterprises and PRC subsidiaries may be required to spend
valuable resources to comply with Bulletin 7 or  to  establish that  we  and  our non-resident enterprises
should not be taxed under Bulletin 7, for  our previous and future restructuring or disposal  of shares of
our  offshore subsidiaries, which may have a material adverse effect  on our financial condition and
results of operations.

The PRC tax authorities have the discretion under Bulletin 7  to  make adjustments to the taxable
capital gains based on the difference  between the  fair value of the  taxable assets transferred and  the
cost of investment. If the PRC tax authorities make adjustments to the  taxable  income  of the
transactions under Circular 698/Bulletin  7, our income tax costs  associated with  such potential
acquisitions or disposals will increase, which  may  have an  adverse effect  on  our financial condition and
results of operations.

Restrictions on currency exchange may limit  our ability to  utilize our revenue  effectively.

The PRC government imposes controls  on the  convertibility of  RMB into foreign currencies  and,
in certain cases, the remittance of currency out  of  China.  A portion of our revenue may in  the future
be denominated in RMB. Shortages in availability of foreign currency  may then restrict  the ability of
our  PRC subsidiaries to remit sufficient  foreign currency  to our offshore entities for our  offshore
entities to pay dividends or make other  payments or otherwise to satisfy our  foreign currency
denominated obligations. The RMB is  currently convertible under  the ‘‘current account,’’  which
includes dividends, trade and service-related foreign exchange transactions,  but not under the ‘‘capital
account,’’ which includes foreign direct  investment and loans, including loans we  may secure from our
onshore subsidiaries. Currently, our PRC  subsidiaries, which are wholly-foreign owned enterprises, may
purchase foreign currency for settlement of ‘‘current account  transactions,’’ including payment  of
dividends to us, without the approval  of SAFE by complying with certain procedural requirements.
However, the relevant PRC governmental authorities  may  limit or eliminate our ability to purchase
foreign currencies in the future for current account  transactions. Since a portion  of  our  future revenue
may be denominated in RMB, any existing and future restrictions on currency exchange may limit  our
ability to utilize revenue generated in  RMB to fund our business activities outside of the  PRC or pay
dividends in foreign currencies to our  shareholders, including holders of the ADSs. Foreign exchange
transactions under the capital account remain  subject to limitations and  require  approvals from, or
registration with, SAFE and other relevant PRC governmental  authorities. This could affect our ability
to obtain foreign currency through debt  or equity financing for our subsidiaries.

Recent litigation and negative publicity  surrounding China-based companies listed in the United  States  may
result in increased regulatory scrutiny of  us and negatively impact the trading price of the ADSs and could
have a material adverse effect upon our  business, including its results  of operations, financial condition, cash
flows and prospects.

We  believe that litigation and negative  publicity surrounding companies with operations in China
that are listed in the United States have  negatively impacted stock prices  for such companies. Various
equity-based research organizations have  published reports on China-based companies after  examining,
among other things, their corporate governance practices, related party transactions, sales practices and
financial statements that have led to special investigations and  stock suspensions on  national exchanges.
Any similar scrutiny of us, regardless of  its lack  of  merit, could result  in a diversion of management

139

resources and energy, potential costs  to  defend ourselves against  rumors, decreases  and volatility in  the
ADS trading price, and increased directors and officers insurance premiums and  could  have a material
adverse effect upon our business, including its results  of operations, financial condition, cash  flows  and
prospects.

The audit report included in this Annual  Report is prepared by auditors who are not inspected fully by the
Public Company Accounting Oversight Board, or the  PCAOB, and, as such, our shareholders are deprived  of
the benefits of such inspection.

As an auditor of companies that are publicly  traded in  the United States  and a  firm  registered  with

the PCAOB, Ernst & Young Hua Ming  LLP  is required under  the laws  of the United States to
undergo regular inspections by the PCAOB. However, because  we  have substantial  operations within
the PRC, a jurisdiction where the PCAOB  is currently unable  to  conduct inspections without  the
approval of the Chinese government  authorities,  our  auditor and its audit  work is  not  currently
inspected fully by the PCAOB.

Inspections of other auditors conducted  by the PCAOB  outside  China have  at times identified
deficiencies in those auditors’ audit procedures and  quality control procedures, which may be addressed
as part of the inspection process to improve future  audit quality. The lack of  PCAOB inspections of
audit work undertaken in China prevents  the PCAOB from regularly evaluating  our auditor’s audits
and its quality control procedures. As  a result, shareholders may be deprived of the benefits of PCAOB
inspections, and may lose confidence  in  our reported financial  information and procedures and the
quality of our financial statements.

Proceedings instituted by the SEC against  five PRC-based accounting firms,  including our independent
registered public accounting firm, could result in our financial statements being determined to  not  be  in
compliance with the requirements of the  Exchange  Act.

In December 2012, the SEC brought  administrative proceedings against  five accounting firms in
China, including our independent registered public  accounting firm, alleging  that  they had refused to
produce audit work papers and other  documents  related to certain  other  PRC-based  companies under
investigation by the SEC. On January  22, 2014, an  initial administrative law  decision was issued,
censuring these accounting firms and  suspending four  of  these firms from practicing  before the  SEC for
a period of six months. The decision is neither final nor  legally  effective  unless and until reviewed  and
approved by the SEC. On February 12,  2014, four of these PRC-based accounting firms appealed  to  the
SEC against this decision. In February  2015, each of  the four PRC-based accounting firms agreed  to  a
censure and to pay a fine to the SEC to settle the  dispute and avoid suspension of their ability to
practice before the SEC. These firms’  ability to continue to serve all  their respective clients is not
affected by the settlement. The settlement requires these firms to follow detailed procedures to seek to
provide the SEC with access to Chinese firms’ audit  documents via the China Securities Regulatory
Commission. If these firms do not follow these  procedures,  the SEC could impose  penalties  such as
suspensions, or it could restart the administrative proceedings. The settlement  did not require these
firms to admit to any violation of law and preserves these firms’ legal defenses in the  event the
administrative proceeding is restarted. In the  event that the SEC  restarts the administrative
proceedings, depending upon the final outcome, listed  companies in  the United States  with major  PRC
operations may find it difficult or impossible  to  retain  auditors in  respect of their operations in the
PRC, which could result in financial  statements  being determined to not be in  compliance with  the
requirements of the Exchange Act, including  possible delisting. Moreover, any  negative news  about the
proceedings against these audit firms may  cause investor  uncertainty regarding PRC-based, United
States-listed companies and the market  price  of  the ADSs  may  be  adversely affected.

If our independent registered public  accounting firm was denied, even temporarily, the  ability to
practice before the SEC and we were  unable to timely find  another registered  public  accounting firm to

140

audit and issue an opinion on our financial  statements,  our financial statements  could  be  determined
not to be in compliance with the requirements of  the Exchange Act. Such a determination could
ultimately lead to deregistration from  the SEC,  which would  substantially reduce or  effectively
terminate the trading of the ADSs in  the United States. Moreover, any negative news  about the
proceedings against these audit firms may  adversely affect investor  confidence in  companies with
substantial mainland China-based operations listed  in the United States. All these would materially  and
adversely affect the market price of the ADSs and substantially reduce or  effectively terminate the
trading of the ADSs in the United States.

Risks Related to the American Depositary Shares

The trading prices of the ADSs are likely  to  be volatile, which could result in substantial losses to you.

We  completed our initial public offering on  February  8, 2016, and there has been  a public market
for the ADSs for only a short period of  time.  The trading  price of the  ADSs is likely to be volatile and
could fluctuate widely in response to  a variety of factors, many of which are beyond  our  control.  In
addition, the performance and fluctuation  of the market prices of other companies  with business
operations located mainly in China that have  listed their securities  in the United States may affect the
volatility in the price of and trading volumes for the ADSs. Some of these companies have  experienced
significant volatility, including significant price declines  after their  initial public offerings. The trading
performances of these PRC companies’  securities  at the  time  of  or  after their offerings may affect the
overall investor sentiment towards other PRC  companies listed in the United States and consequently
may impact the trading performance of the ADSs.

In addition to market and industry factors, the price  and trading volume for  the ADSs may be

highly volatile for specific business reasons,  including:

(cid:129) announcements  of regulatory approval  or a complete response letter, or specific label indications

or patient populations for its use, or changes  or delays  in the regulatory review process;

(cid:129) announcements  of therapeutic innovations  or new  products by us or our competitors;

(cid:129) adverse actions taken by regulatory  agencies with respect to our clinical trials, manufacturing

supply chain or sales and marketing activities;

(cid:129) any adverse changes to our relationship with manufacturers or suppliers;

(cid:129) the results of our testing and clinical trials;

(cid:129) the results of our efforts to acquire  or license  additional drug candidates;

(cid:129) variations in the level of expenses related  to  our  existing drug candidates or preclinical  and

clinical development programs;

(cid:129) any intellectual property infringement  actions in  which we  may become  involved;

(cid:129) announcements  concerning our competitors or the  pharmaceutical industry  in general;

(cid:129) achievement of expected product sales and profitability;

(cid:129) manufacture, supply or distribution shortages;

(cid:129) variations in our results of operations;

(cid:129) announcements  about our earnings that  are not in line with analyst  expectations, the risk of

which  is enhanced because it is our policy not to give guidance on earnings;

(cid:129) publication of operating or industry metrics by third parties, including government  statistical

agencies, that differ from expectations of industry or  financial  analysts;

141

(cid:129) changes in financial estimates by securities  research  analysts;

(cid:129) announcements  made by us or our  competitors of  new product and service  offerings,

acquisitions, strategic relationships, joint ventures  or capital commitments;

(cid:129) press reports, whether or not true, about our business;

(cid:129) additions to or departures of our management;

(cid:129) fluctuations of exchange rates between the RMB and the U.S. dollar;

(cid:129) release or expiry of lock-up or other transfer restrictions on our outstanding ordinary shares  or

ADSs;

(cid:129) sales or perceived potential sales of additional ordinary  shares  or  ADSs;

(cid:129) sales of the ADSs by us, our executive officers  and directors or our shareholders  in the future;

(cid:129) general economic and market conditions and overall fluctuations  in the U.S. equity markets;

(cid:129) changes in accounting principles;

(cid:129) changes or developments in the PRC or global regulatory environment; and

(cid:129) the outcome of proceedings recently instituted by the  SEC against five  PRC-based accounting

firms, including the affiliate of our independent  registered public accounting firm.

Any of these factors may result in large and sudden changes  in the volume  and trading price  of  the

ADSs. In the past, following periods of volatility in the market price of a company’s securities,
shareholders have often instituted securities class action litigation  against that company.  If we  were
involved in a class action suit, it could  divert the attention  of  management, and, if adversely
determined, have a material adverse effect on  our  financial condition and  results of operations.

In addition, the stock market, in general, and small  pharmaceutical and biotechnology companies

have experienced extreme price and volume  fluctuations that have  often been unrelated  or
disproportionate to the operating performance  of  these companies. Broad  market and industry factors
may negatively affect the market price of the ADSs, regardless of  our actual operating  performance.
Further, the current decline in the financial markets and related factors  beyond our  control may cause
the ADSs price to decline rapidly and unexpectedly.

We may  be subject to securities litigation, which is expensive and could divert  management attention.

The ADS price may be volatile, and  in the  past companies that  have experienced volatility in  the

market price of their ADSs have been subject  to  an increased incidence  of  securities class action
litigation. We may be the target of this type  of litigation in  the future.  Securities litigation  against us
could result in substantial costs and divert  our management’s attention from  other  business  concerns,
which  could seriously harm our business.

Future sales of the ADSs in the public market could cause the ADS  price to fall.

The ADS price could decline as a result  of  sales  of  a large number of  the  ADSs or the  perception
that these sales could occur. These sales, or the possibility that these sales may occur, also might  make
it more difficult for us to sell equity securities in the future at a time and at a price  that  we deem
appropriate.

As of March 17, 2017, we had 518,602,349 ordinary shares  outstanding, of which 251,251,247

ordinary shares were held in the form  of 19,327,019  American Depositary  Shares.

142

We  have or will register the offer and sale  of  all ordinary shares that  we may issue under  our
equity compensation plans, including upon the exercise of share options. These ordinary  shares can be
freely sold in the public market upon issuance.

As of March 17, 2017, the holders of  approximately 300,990,453 ordinary shares, or 58%,  of  our

outstanding ordinary shares, will have rights, subject  to  some  conditions, to  require us to file
registration statements covering the sale of their ordinary shares or to include their ordinary  shares in
registration statements that we may file  for ourselves or other shareholders. Once  we register the  offer
and sale of ordinary shares for the holders of registration  rights, they can  be  freely  sold  in the public
market.

In addition, in the future, we may issue  additional ordinary shares or other equity or  debt
securities convertible into ordinary shares in connection with a financing,  acquisition,  litigation
settlement, employee arrangements or  otherwise. Any such issuance could result in substantial dilution
to our existing shareholders and could  cause the ADS  price to decline.

We are currently an ‘‘emerging growth  company.’’  As  a result  of the reduced disclosure requirements
applicable to emerging growth companies,  the ADSs may be less attractive  to  investors.

We  are currently an ‘‘emerging growth company,’’ as  defined  in the JOBS Act. For so  long as  we
remain an emerging growth company,  we are permitted  and intend to rely on  some of the  exemptions
from certain reporting requirements that are applicable  to  other public companies that are  not
emerging growth companies. These exemptions include but are not limited to not being required to
comply  with the auditor attestation requirements of Section 404  of the Sarbanes-Oxley Act of 2002,  not
being required to comply with any requirement  that  may be adopted  by the Public Company
Accounting Oversight Board regarding  mandatory audit firm  rotation or a supplement  to  the auditor’s
report providing additional information about the audit and  the financial  statements, reduced disclosure
obligations regarding executive compensation  in our periodic reports and  proxy statements,  and
exemptions from the requirements of holding a  non-binding advisory  vote  on executive compensation
and shareholder approval of any golden  parachute payments  not previously approved.

We  cannot predict whether investors  will  find the ADSs  less attractive because  we will rely on
these exemptions. If some investors find  the  ADSs less  attractive as a result, there may be a less active
trading market for the ADSs and the ADS price  may  be  more volatile.

Because we do not expect to pay dividends  in  the foreseeable future, you  must rely on price  appreciation of the
ADSs for return on your investment.

We  intend to retain most, if not all, of  our  available funds  and earnings to fund the development
and growth of our  business. As a result, we do not expect  to pay any cash  dividends  in the foreseeable
future. Therefore, you should not rely  on  an investment in  the ADSs as a source for  any future
dividend income.

Our board of directors has significant discretion as to whether to distribute  dividends.  Even if our

board of directors decides to declare and pay dividends,  the timing, amount and form of future
dividends, if any, will depend on, among  other  things, our  future results  of operations and  cash flow,
our  capital requirements and surplus,  the amount of  distributions,  if any,  received by us  from our
subsidiaries, our financial condition,  contractual restrictions and  other factors deemed  relevant by our
board of directors. Accordingly, the return on your investment in the  ADSs will likely  depend  entirely
upon any future price appreciation of  the  ADSs. There  is no guarantee that the ADSs will appreciate
in value or even maintain the price at  which you purchased  the  ADSs. You may not realize  a return on
your investment in the ADSs and you may even lose your entire investment in  the ADSs.

143

If securities or industry analysts do not publish research  or publish inaccurate or  unfavorable research  about
our business, the market price for the ADSs  and trading volume could decline.

The trading market for the ADSs relies in part on the research and reports  that  equity research

analysts publish about us or our business.  We  do  not control these  analysts. If research analysts  do  not
establish and maintain adequate research coverage or if one or  more of the analysts who  covers us
downgrades the ADSs or publishes inaccurate or  unfavorable research about our business, the market
price for the ADSs would likely decline.  If one or  more  of these analysts cease  coverage  of  our
company or fail to publish reports on us  regularly,  we could lose  visibility in  the financial  markets,
which,  in turn, could cause the market price or  trading volume for the ADSs to decline  significantly.

We are a Cayman Islands company. Because  judicial precedent regarding  the rights of shareholders is more
limited under Cayman Islands law than under  U.S. law, shareholders may  have  fewer shareholder rights than
they would have under U.S. law.

Our corporate affairs are governed by our amended  and restated memorandum and  articles  of
association (as may be amended from  time to time), the Companies Law (as  amended) of the Cayman
Islands and the common law of the Cayman Islands.  The  rights of shareholders to take  action against
the directors, actions by minority shareholders and the fiduciary responsibilities of our directors are to
a large extent governed by the common law of  the Cayman Islands.  This  common  law is derived in part
from comparatively limited judicial precedent in the  Cayman Islands as well as  from English common
law, which has persuasive, but not binding, authority on  a court  in the Cayman Islands. The rights of
our  shareholders and the fiduciary responsibilities of our directors  under Cayman Islands law are  not  as
clearly  established as they would be under statutes or judicial precedent  in some jurisdictions in the
United States. In particular, the Cayman Islands  has a less developed body  of securities law than the
United States. In addition, some states  in the United  States, such as  Delaware, have  more fully
developed and judicially interpreted bodies of corporate  law  than the  Cayman Islands.

In addition, as a Cayman Islands exempted  company, our shareholders  have  no general rights
under Cayman Islands law to inspect corporate records  and  accounts or to obtain copies of lists of
shareholders of these companies with  the exception that  the shareholders may  request  a copy of the
current amended and restated memorandum and articles of association. Our  directors have  discretion
under our amended and restated articles  of association to determine  whether or not, and under  what
conditions, our corporate records may be inspected by our shareholders, but are not obliged to make
them available to our shareholders. This  may  make it more difficult for  you to obtain the  information
needed to establish any facts necessary  for a shareholder motion  or  to  solicit proxies  from other
shareholders in connection with a proxy contest. As a  Cayman Islands company, we may  not  have
standing to initiate a derivative action  in a  federal court of the United  States. As a result, you  may be
limited in your ability to protect your  interests  if you are harmed in a manner  that  would otherwise
enable you to sue in a United States federal  court. In addition, shareholders of  Cayman Islands
companies may not have standing to initiate a shareholder derivative action  in U.S.  federal courts.

As a result of all of the above, public shareholders  may  have more difficulty in protecting  their
interests in the face of actions taken by  management, members of  the  board of  directors or  controlling
shareholders than they would as public  shareholders  of  a U.S.  company.

You may face difficulties in protecting your interests, and your ability to protect your rights through the U.S.
federal courts may be limited because we  are incorporated  under  Cayman Islands law,  we currently conduct
substantially all of our operations outside  the United States and some of our directors and  executive officers
reside outside the United States.

We  are incorporated in the Cayman Islands and currently conduct substantially all of our
operations outside the United States  through  our  subsidiaries.  Some  of  our directors and executive

144

officers reside outside the United States  and a substantial portion  of their  assets are  located  outside of
the United States. As a result, it may  be  difficult or  impossible for you to bring an  action against us  or
against these individuals in the Cayman Islands or  in China in the event that you  believe that your
rights have been infringed under the  securities laws of the  United States or  otherwise. Even if you are
successful in bringing an action of this  kind, the laws of  the Cayman Islands and  China may  render  you
unable to enforce a judgment against  our assets or the assets of our directors and officers. There is no
statutory recognition in the Cayman Islands  of judgments obtained in the United States or China,
although the courts of the Cayman Islands  will  generally  recognize and  enforce a non-penal judgment
of a foreign court of competent jurisdiction without retrial on the  merits.

Your voting rights as a holder of the ADSs are limited by  the  terms of the deposit  agreement,  as  amended.

You may exercise your voting rights with respect to the ordinary shares  underlying your ADSs  only

in accordance with the provisions of  the deposit agreement, as  amended. Upon receipt of  voting
instructions from you in the manner  set  forth in  the deposit  agreement,  the depositary  for the  ADSs
will endeavor to vote your underlying  ordinary shares in accordance with these instructions. Under our
articles of association, the minimum notice period required for convening a general meeting is  seven
calendar days. When a general meeting is convened, you  may  not receive sufficient notice  of a
shareholders’ meeting to permit you  to withdraw your ordinary shares to allow you to cast your  vote
with respect to any specific matter at the  meeting. In addition,  the depositary and its agents may  not be
able to send voting instructions to you or carry out your voting instructions in  a timely manner. We will
make all reasonable efforts to cause  the depositary to extend voting  rights to you in a  timely manner,
but you may not receive the voting materials  in time to ensure  that you can instruct the depositary to
vote your shares. Furthermore, the depositary and  its  agents  will not be responsible for  any failure  to
carry out any instructions to vote, for the  manner in  which any vote is cast  or for  the effect of any such
vote. As a result, you may not be able to exercise your right to vote  and you may  lack  recourse  if  your
ordinary shares are not voted as you requested.

Anti-takeover provisions in our charter documents  may  discourage our acquisition  by a third party, which
could limit our shareholders’ opportunity  to  sell  their  shares,  including ordinary shares represented by the
ADSs, at a premium.

Our amended and restated memorandum and articles of association include provisions that could

limit the ability of others to acquire control of  our  company, could  modify our structure  or could cause
us to engage in change-of-control transactions. These provisions could  have the effect of depriving our
shareholders of an opportunity to sell  their shares, including ordinary  shares represented  by  ADSs, at  a
premium over prevailing market prices  by  discouraging third parties from  seeking  to  obtain  control in a
tender offer or similar transaction.

For example, our board of directors has the authority, without further action by our shareholders,

to issue preferred shares in one or more  series  and  to  fix  the powers and rights of these shares,
including dividend rights, conversion rights, voting rights,  terms of redemption and liquidation
preferences, any or all of which may  be greater than the rights associated with our ordinary shares.
preferred shares could thus be issued quickly with terms  calculated to delay  or prevent a  change  in
control or make removal of management more  difficult. In addition,  if our board of directors
authorizes the issuance of preferred shares, the market price of the ADSs may fall and  the voting and
other rights of the holders of our ordinary shares may be materially and adversely  affected.

Furthermore, the amended and restated articles  of  association permit the  directors to vary all or

any of the rights attaching to any shares in issue without the  consent  of the shareholder but only if
such variation is considered by the directors not to have a material adverse effect upon such  holder.
The directors cannot vary the rights  of shares if  such variation would  have a material adverse effect of

145

the holder. The amended and restated articles of association provide that the holders  must  consent  to
any such material adverse changes in  the manner set out therein.

Because our directors are divided into three classes with staggered terms of  three years each,
shareholders can only elect or remove a  limited  number of our  directors in  any given year.  The length
of these  terms could present an obstacle  to certain  actions, such as a merger or other  change  of
control, which could be in the interest of our shareholders.

Our amended and restated memorandum  and articles of  association provide that  any  shareholder  bringing an
unsuccessful action against us may be  obligated to reimburse us for  any costs  we have incurred in  connection
with such unsuccessful action.

Our amended and restated memorandum and articles of association provide that under certain
circumstances the fees, costs, and expenses that we incur in connection with actions or proceedings
brought by any person or entity, which  we  refer to as  claiming  parties, may be shifted  to  such person or
entity. If a claiming party asserts any  claim; initiates  any  proceeding; or joins,  offers substantial
assistance to, or has a direct financial interest in  any  claim or proceeding against us (including  any
proceeding purportedly filed on behalf of us or  any  shareholder), and such  claiming  party (or the third
party that received substantial assistance from a claiming party or in whose claim or proceeding such
claiming party has a direct financial interest) is  unsuccessful  in obtaining a judgment on the merits  in
which  the claiming party prevails, then such claiming party may,  to  the  fullest extent permissible by law,
be obligated jointly and severally to reimburse us for all fees, costs, and expenses, including but  not
limited to all  reasonable attorneys’ fees and other litigation expenses,  that  we may  incur  in connection
with such claim, suit, action, or proceeding.

Fee-shifting articles are relatively new and untested in both the  Cayman Islands  and the  United
States. The case law and potential legislative action on fee-shifting  articles are evolving and there exists
considerable uncertainty regarding the validity of,  and potential  judicial and  legislative  responses to,
such articles. For example, it is unclear  whether our ability to invoke our  fee-shifting article in
connection with claims under the federal securities laws, including claims related to any  of our  public
offerings, would be preempted by federal  law.  Similarly,  it is unclear how  courts might  apply the
standard that a claiming party must obtain  a judgment  that substantially  achieves, in substance and
amount, the full remedy sought. The  application  of  our  fee-shifting article  in connection with such
claims, if any, will depend in part on future  developments of the law. We cannot assure  you that we
will or will not invoke our fee-shifting article in any particular  dispute,  including any claims related  to
our  public offerings. Consistent with our  directors’ fiduciary  duties to act  in the  best interests of the
company, the directors may in their sole discretion from time to time decide whether or  not  to  enforce
this  article. In addition, given the unsettled state of the law related to fee-shifting articles, such as ours,
we may incur significant additional costs associated  with resolving  disputes  with respect to such articles,
which  could adversely affect our business and  financial condition.

If a  shareholder that brings any such claim, suit,  action or  proceeding is  unable  to  obtain  the
judgment sought, the attorneys’ fees  and  other  litigation  expenses that  might  be  shifted to a claiming
party are potentially significant. This fee-shifting article, therefore, may dissuade  or discourage current
or former shareholders (and their attorneys) from initiating lawsuits  or  claims against  us.  In  addition, it
may impact the fees, contingency or  otherwise, required by  potential plaintiffs’ attorneys to represent
our  shareholders or otherwise discourage  plaintiffs’ attorneys from representing our shareholders at all.
As a result, this article may limit the  ability  of shareholders to affect the management  and direction of
our  company, particularly through litigation or the  threat of litigation.

146

The depositary for the ADSs will give us  a discretionary  proxy to vote our ordinary  shares  underlying your
ADSs if you do not vote at shareholders’  meetings, except  in limited  circumstances,  which could  adversely
affect your interests.

Under the deposit agreement, as amended,  for  the ADSs, the depositary will give us a

discretionary proxy to vote our ordinary shares  underlying your ADSs at shareholders’  meetings if you
do not give voting instructions to the  depositary, unless:

(cid:129) we have failed to timely provide the depositary with our notice of meeting and related  voting

materials;

(cid:129) we have instructed the depositary that we do not wish a  discretionary  proxy to be given;

(cid:129) we have informed the depositary that there is substantial opposition as to a  matter to be voted

on at the meeting; or

(cid:129) a matter to be voted on at the meeting would have a material adverse impact on shareholders.

The effect of this discretionary proxy  is that, if you fail to give voting  instructions to the depositary,

you cannot prevent our ordinary shares underlying  your ADSs  from  being  voted, absent  the situations
described above, and it may make it more  difficult  for shareholders to influence our  management.
Holders of our ordinary shares are not  subject to this  discretionary proxy.

Holders of the ADSs may be subject to limitations on transfer of their ADSs.

Your ADSs are transferable on the books of the depositary. However, the depositary may close  its

books at any time or from time to time when  it deems expedient in connection with the  performance of
its  duties. The depositary may refuse to deliver, transfer or  register transfers of your  ADSs generally
when our books or the books of the depositary  are closed, or at any time if we or the depositary think
it is advisable to do so because of any  requirement  of law, government  or governmental body, or under
any provision of the deposit agreement, as amended, or  for any  other reason, subject to your right  to
cancel your ADSs and withdraw the  underlying ordinary shares. Temporary delays in the cancellation of
your ADSs and withdrawal of the underlying  common shares may  arise because  the depositary  has
closed its transfer books or we have closed our  transfer  books, the transfer of ordinary shares is
blocked to permit voting at a shareholders’ meeting or we are paying a  dividend on our  ordinary
shares.

In addition, you may not be able to cancel  your ADSs and withdraw  the underlying ordinary  shares

when you owe money for fees, taxes and  similar charges and  when it is necessary to prohibit
withdrawals in order to comply with  any laws or governmental  regulations  that  apply to ADSs  or to the
withdrawal of ordinary shares or other  deposited securities.

The depositary for the ADSs is entitled  to charge  holders fees for various  services, including annual service
fees.

The depositary for the ADSs is entitled to charge  holders fees  for various services including for the
issuance of ADSs upon deposit of ordinary  shares, cancellation of ADSs,  distributions of cash dividends
or other  cash distributions, distributions of ADSs pursuant  to  share dividends or other free share
distributions, distributions of securities other than ADSs  and annual service fees. In the case  of ADSs
issued by the depositary into The Depository Trust  Company, or DTC, the fees will be charged by the
DTC participant to the account of the  applicable beneficial owner in accordance  with the procedures
and practices of the DTC participant as  in effect at the time.

147

You may not receive distributions on our  ordinary shares or any  value  for them if  it is illegal or impractical
to make them available to you.

The depositary of  the ADSs has agreed to pay you the cash dividends  or other distributions  it or

the custodian for the ADSs receives on  our ordinary shares or other deposited  securities after
deducting its fees and expenses. You will receive these distributions in proportion to the number of our
ordinary shares that your ADSs represent. However, the depositary is not responsible for making such
payments or distributions if it is unlawful  or impractical to make a distribution  available  to  any holders
of ADSs. For example, it would be unlawful to make  a distribution to a holder  of ADSs if it consists  of
securities that require registration under  the Securities  Act but that are not properly registered or
distributed pursuant to an applicable  exemption from registration. The  depositary is  not  responsible  for
making a distribution available to any  holders  of ADSs if any government approval or registration
required for such distribution cannot be obtained  after reasonable efforts  made by the  depositary. We
have no obligation to take any other action to permit the distribution  of  the ADSs,  ordinary shares,
rights or anything else to holders of the ADSs. This means that  you may not receive  the distributions
we make on our ordinary shares or any value for them if it  is illegal or impractical for us to make them
available to you. These restrictions may materially  reduce the value of  your  ADSs.

Holders of the ADSs may not be able to  participate in rights  offerings and may experience dilution of their
holdings.

From time to time, we may distribute  rights to our  shareholders, including rights to acquire
securities. Under the deposit agreement,  the depositary will  not distribute rights to holders of ADSs
unless the distribution and sale of rights and the securities  to which these rights  relate  are either
exempt from registration under the Securities Act with respect to all holders of  ADSs or are  registered
under the provisions of the Securities Act.  The  depositary may,  but  is not required to, attempt to sell
these undistributed rights to third parties  and  may allow the rights  to  lapse. We  may be unable to
establish an exemption from registration under  the Securities Act,  and  we are under no  obligation to
file a registration statement with respect to these rights  or underlying securities  or to try to have a
registration statement declared effective.  Accordingly, holders of  ADSs may be unable  to  participate in
our  rights offerings and may experience  dilution of their holdings as  a result.

Our corporate actions are substantially  controlled by our directors, executive officers and other principal
shareholders, who can exert significant influence over important corporate matters, which may reduce the
price of  the ADSs and deprive you of an opportunity to receive a premium for your ADSs.

Our directors, executive officers and  principal shareholders  beneficially owned approximately
69.8% of our outstanding ordinary shares as  of  March 17,  2017. These shareholders, if acting together,
could exert substantial influence over  matters such as  electing  directors and approving material
mergers,  acquisitions or other business combination  transactions. This concentration of ownership may
also discourage, delay or prevent a change in  control  of our  company, which  could  have the dual effect
of depriving our shareholders of an opportunity to receive a premium for their shares as part of a sale
of our company and reducing the price  of  the ADSs. These actions  may  be  taken even if they are
opposed by our other shareholders, including the holders of the  ADSs. In addition, these  persons could
divert business opportunities away from  us  to  themselves or  others.

We have  incurred increased costs as a result of operating  as a public company, and  our management will be
required to devote substantial time to new  compliance initiatives and corporate  governance practices.

As a public company, we have incurred and will continue  to  incur significant legal, accounting and

other expenses that we did not incur as  a private company. For example,  as  a public company, we are
now subject to the reporting requirements  of the Exchange  Act, which  requires, among other things,
that we file with the SEC annual, quarterly and current  reports with  respect to our business and

148

financial condition. We have incurred and  will  continue to incur costs associated with  the preparation
and filing of these reports. The Sarbanes-Oxley Act of 2002, the  Dodd-Frank  Wall  Street Reform and
Consumer Protection Act, the listing  requirements  of the NASDAQ Stock Market and other applicable
securities rules and regulations impose various requirements on public companies, including
establishment and  maintenance of effective disclosure and financial controls  and corporate governance
practices. Our management and other personnel  will need to devote a substantial amount of  time to
these compliance initiatives. Moreover,  these rules and regulations will  increase our legal and financial
compliance costs and will make some  activities more time-consuming and costly. For  example, we
expect that these rules and regulations may make it  more difficult and  more expensive for us to obtain
director and officer liability insurance, which  in turn could make it  more difficult for us to attract and
retain qualified members of our board of  directors.

We  continue to evaluate these rules and regulations,  and  cannot predict or estimate the amount of
additional costs we may incur or the timing  of such costs. These rules and regulations are often subject
to varying interpretations, in many cases  due to their lack of  specificity, and, as a result, their
application in practice may evolve over time as new guidance is  provided  by  regulatory and governing
bodies. This could result in continuing  uncertainty regarding  compliance matters and  higher costs
necessitated by ongoing revisions to disclosure and governance practices.

Pursuant to Section 404 of the Sarbanes-Oxley Act of  2002, or Section  404, we  will first be

required to furnish a report by our management on our internal control over financial  reporting for  the
year ending December 31, 2016. However, while we remain  an emerging growth company, we will  not
be required to include an attestation  report on internal control over  financial reporting issued by our
independent registered public accounting  firm. To  achieve compliance with Section 404 within the
prescribed period, we will continue to  be  engaged in a process  to  document and evaluate our internal
control over financial reporting, which  is both costly  and challenging. In this regard,  we will need to
continue to dedicate internal resources, potentially  engage outside consultants and  adopt a  detailed
work plan to assess and document the  adequacy of internal control over  financial reporting, continue
steps to improve control processes as appropriate, validate through testing that controls are  functioning
as documented and implement a continuous  reporting and improvement process for internal control
over financial reporting. Despite our efforts, there  is a  risk that  we will not be able to conclude,  within
the prescribed timeframe or at all, that  our internal  control over  financial reporting  is effective as
required by Section 404. If we identify one or more material weaknesses, it could result  in an adverse
reaction in the financial markets due to a  loss of confidence in the reliability of our financial
statements.

We may  be a ‘‘passive foreign investment company,’’ which  may  have adverse U.S.  federal  income  tax
consequences for U.S. shareholders.

U.S. investors should be aware that, based on current business plans and financial expectations
(including that a substantial percentage  of our assets are  held in cash and cash equivalents), we expect
that we may be a passive foreign investment  company within the  meaning of Section 1297 of the
Internal Revenue Code of 1986, as amended, or PFIC, for the  current taxable year and in future
taxable years. If we are a PFIC for any  taxable  year  during a U.S. shareholder’s holding period of the
ADSs or ordinary shares, then such U.S. shareholder  generally  will be required  to  treat  any gain
realized upon a disposition of the ADSs  or ordinary shares, or any ‘‘excess  distribution’’ received on  the
ADSs or ordinary shares, as ordinary  income earned  over the U.S.  shareholder’s holding period for the
ADSs or ordinary shares, and to pay  the  applicable taxes on such ordinary income along  with an
interest charge at the rate applicable to underpayments  of tax on a portion of the  resulting tax liability,
unless the shareholder makes a timely  and effective ‘‘qualified electing fund’’ election,  or QEF election,
or ‘‘mark-to-market’’ election with respect  to the ADSs  or ordinary shares. A U.S.  shareholder who
makes an effective QEF election generally must report on a  current basis  its  share of our net capital

149

gain and ordinary  earnings for any taxable year in which we are a  PFIC, whether or not we distribute
any amounts to our shareholders. If a  QEF election  is not in effect  for  the first taxable year in your
holding period in which we are a PFIC,  a QEF election can only  be  made  if you elect to recognize gain
as if you had sold the ADSs or ordinary  shares for  their  fair market value on the first day of your
taxable year in which the PFIC becomes a QEF  pursuant to the QEF election. The gain recognized on
this  deemed sale would be subject to  the general tax treatment  of  PFICs  discussed above. We intend to
determine our PFIC status at the end  of each taxable year  and to satisfy any  applicable  record keeping
and reporting requirements that apply  to  a QEF, and will endeavor  to  provide to you,  for each taxable
year that we determine we are or may be a PFIC, the  information  that is necessary for you  to  make a
QEF election with respect to us (and any  of our subsidiaries which are lower-tier PFICs). We  may elect
to provide such information on our website.  However,  there can be no  assurances that we will  make
the necessary information available to you.  You are urged to consult your own  tax advisors regarding
the availability of, and procedure for making, a  QEF election.  A U.S. shareholder who makes an
effective mark-to-market election generally must include as ordinary income  any gain  recognized in  a
year that we are a  PFIC in an amount  equal to the  excess  of the fair market  value of the  ADSs over
the shareholder’s adjusted tax basis therein. Each  U.S. shareholder  should consult its own  tax advisors
regarding the PFIC rules and the U.S.  federal income tax consequences of the acquisition, ownership
and disposition of the ADSs or ordinary shares.

If you  are a ‘‘Ten Percent Shareholder,’’  you  may be subject to adverse U.S. federal income  tax consequences if
we are classified as a Controlled Foreign  Corporation.

Each  ‘‘Ten Percent Shareholder’’ (as defined below) in  a non-U.S. corporation that is classified as

a ‘‘controlled foreign corporation,’’ or a CFC, for U.S. federal income tax purposes generally is
required to include in income for U.S. federal  tax purposes such Ten Percent Shareholder’s pro  rata
share of the ‘‘CFC’s’’ ‘‘Subpart F income’’  and investment  of earnings  in U.S.  property, even  if  the
CFC has made no distributions to its  shareholders. A non-U.S.  corporation  generally  will  be  classified
as a CFC for U.S federal income tax purposes if Ten  Percent Shareholders  own in the  aggregate,
directly or indirectly, more than 50%  of  either the total combined voting  power  of all classes of stock
of such corporation entitled to vote or of the total value  of  the stock of such  corporation. A  ‘‘Ten
Percent Shareholder’’ is a U.S. person (as defined by the Internal Revenue Code of 1986, as amended),
who owns or is considered to own 10%  or more  of  the total combined voting power of all classes of
stock entitled to vote of such corporation. The determination of CFC  status is complex and includes
attribution rules, the application of which is not entirely certain. We may currently be a CFC and/or we
may become one in the future. Holders  are urged to consult their own tax advisors with  respect to our
potential CFC status and the consequences  thereof.

We may  be subject to adverse legislative  or regulatory tax changes  that  could  negatively affect our financial
condition.

The rules dealing with U.S. federal, state  and  local income taxation  are constantly under review by
persons involved in the legislative process and by the IRS  and the  U.S. Treasury Department. Changes
to tax  laws (which changes may have retroactive application) could adversely affect our stockholders or
us. In recent years, many changes have been made and changes are likely to continue  to  be  made in
the future. We cannot predict whether, when, in what form, or with what effective dates,  tax laws,
regulations and rulings may be enacted, promulgated or  decided that  could result in  an increase in  our,
or our stockholders’, tax liability or require changes in the manner in  which we operate in order to
minimize increases in our tax liability.

Item 2. Properties

Our research and development center is  located in Changping,  Beijing, China, where we lease
approximately 6,900 square meters of  office,  laboratory and  manufacturing space. The lease  for this
facility expires in 2021. In addition, we  lease  an approximately  11,000 square meter space and  are
building a manufacturing facility in Suzhou,  China. Our clinical development office is located in
downtown Beijing, China. We also have offices in the United  States in the  greater Boston  area,
California and New Jersey. We lease all  of our facilities and believe our  current facilities are sufficient
to meet our needs.

On March 7, 2017, we entered into an  agreement with  Guangzhou GET Technology

Development Co., Ltd. pursuant to which we  expect to establish  a  biologics manufacturing facility to
research, develop and produce biologics products in China. Through  a  subsidiary  of a joint venture
company formed in connection with this  agreement, we  expect to acquire at least  100,000 square
meters of land for the facility in the Sino-Singapore Guangzhou Knowledge City.  See  ‘‘Part IV—
Item 15—Exhibits, Financial Statement Schedules—Note 22. Subsequent Events’’ for additional
information.

Item 3. Legal Proceedings

From time to time we may become involved  in legal  proceedings  or  be  subject to claims arising in

the ordinary course of our business. We  are  not presently a party  to  any legal proceedings  that,  if
determined adversely to us, would individually or  taken  together have a  material adverse effect on our
business, results of operations, financial condition  or cash  flows. Regardless of the  outcome, litigation
can have an adverse impact on us because of defense and settlement  costs, diversion of management
resources and other factors.

Shareholders

As of March 17, 2017, we had approximately  101 holders of  record  of our ordinary  shares and one

holder of record of the ADSs. This number  does not include beneficial owners whose ADSs are held
by nominees in street name. Because many ordinary  shares  held in the form  of ADSs are  held by
broker nominees, we are unable to estimate the  total  number  of holders represented by these record
holders.

Dividend Policy

We  have never declared or paid any dividends on our  ordinary shares or  any other securities. We
currently intend to retain all available  funds and any future earnings, if any, to fund the development
and expansion of our business and we  do  not anticipate paying any cash dividends in the  foreseeable
future. Investors should not purchase  the ADSs with  the expectation of  receiving cash dividends.

Any future determination to pay dividends will be made at the discretion of our board of directors

and may be based on a number of factors, including our future operations and earnings, capital
requirements and surplus, general financial condition, contractual restrictions and other factors that our
board of directors may deem relevant.  If we pay any  dividends,  we will pay the  ADS holders to the
same extent as holders of our ordinary shares,  subject to the terms of the deposit  agreement, as
amended, including the fees and expenses  payable thereunder. Cash dividends on  our ordinary shares,
if any, will be paid in U.S. dollar.

152

If we  pay dividends in the future, in  order for  us  to  distribute dividends to our shareholders and
ADS holders, we will rely to some extent  on any dividends distributed by our  PRC subsidiaries. Any
dividend distributions from our PRC  subsidiaries to us will  be  subject to PRC withholding tax. In
addition, regulations in the PRC currently permit payment of dividends of a PRC  company only out  of
accumulated distributable after-tax profits as  determined  in accordance with its articles of association
and the accounting standards and regulations  in China. See the section of this Annual Report titled
‘‘Part I—Item 1A—Risk Factors—Risks Related to Our Doing Business in the PRC—In the future,  we
may rely to some extent on dividends and other distributions on equity  from our principal operating
subsidiaries to fund offshore cash and  financing requirements.’’

Recent  Sales of Unregistered Securities

We  did not sell any of our ordinary shares  or ADSs, or grant any share options or restricted  share
awards, during the year ended December  31,  2016 that were  not registered under  the Securities Act of
1933, as amended, or the Securities Act, and that have  not  otherwise been  described in  a Quarterly
Report on Form 10-Q.

Issuer  Purchases of Equity Securities

During  the quarter ended December 31, 2016,  there were no  purchases made by us,  on our behalf,

or by any ‘‘affiliated purchasers’’ of shares  of our equity securities.

Use of Proceeds from Registered Securities

On February 8, 2016, we closed the sale  of  7,590,000 ADSs  to  the  public at an initial public
offering price of $24.00 per ADS, including the  exercise in full by the  underwriters of their option to
purchase additional ADSs. The ordinary shares in  the form of ADSs in our initial  public offering were
registered under the Securities Act pursuant to a  registration statements on Form S-1  (File
No. 333-207459), which was filed with  the SEC on October 16,  2015 and amended  subsequently and
declared effective on February 2, 2016. Following  the sale  of  the ADSs in connection with the closing
of our initial public offering, the offering terminated. The offering did not terminate before all the
securities registered in the registration statements were sold. The underwriters of the offering were
Goldman, Sachs & Co., Morgan Stanley, and Cowen and Company acting as  joint  book-running
managers for the offering and as representatives  of  the underwriters.  Baird acted as co-manager  for the
offering.

We  raised $166.2 million in net proceeds  after deducting underwriting  discounts and commissions
and other offering expenses of approximately $16.0  million. No offering expenses were  paid directly or
indirectly to any of our directors or officers (or their associates)  or persons  owning ten percent  or more
of any class of our equity securities or  to  any  other  affiliates.

On November 23, 2016, we closed the sale of 6,631,250  ADSs to the public at a  public  offering

price of $32.00 per ADS, including the exercise in full by  the underwriters  of  their  option to purchase
additional ADSs. In this offering, the  selling shareholders  sold 468,750 ADSs representing  6,093,750
ordinary shares. The ordinary shares in  the form  of ADSs in  this follow-on  public offering were
registered under the Securities Act pursuant to a  registration statements on Form S-1  (File
No.333-214540), which was filed with the  SEC on November 10, 2016  and amended subsequently  and
declared effective on November 17, 2016. Following the sale of  the  ADSs in connection with the
closing of our follow-on public offering, the  offering  terminated. The offering did  not  terminate before
all the securities registered in the registration  statements  were sold. The underwriters of  the offering
were Morgan Stanley; Goldman, Sachs & Co.; and Cowen  and Company  acting as joint book-running
managers for the offering and as representatives  of  the underwriters.  Baird and William Blair  acted  as
co-managers for the offering.

We  raised $198.6 million in net proceeds  after deducting underwriting  discounts and commissions
and other offering expenses of approximately $13.6  million. We did not receive  any proceeds from the
sale of the shares by the selling stockholder. No offering expenses were  paid directly or indirectly to
any of our directors or officers (or their associates)  or persons owning ten percent or  more of any class
of our equity securities or to any other  affiliates.

To date, we have not yet used all of the net proceeds from our initial public offering and follow-on

public offering. We invested the funds  received  in short-term, interest-bearing investment-grade
securities and government securities in  accordance with  our investment policy.  As described in our final
prospectuses filed with the SEC on February 3,  2016 and November 18, 2016, pursuant to Rule 424(b)

154

under the Securities Act, we expect to  use  the net proceeds  from our initial public offering and
follow-on public offerings to fund the costs of  ongoing clinical development for our clinical drug
candidates, BGB-3111, BGB-A317, BGB-290 and BGB-283,  and  preclinical drug candidates, as well as
for working capital, capital expenditures and general corporate purposes.

Taxation

Cayman Islands Taxation

The Cayman Islands currently levies no taxes  on individuals or corporations  based upon profits,
income, gains or appreciation and there is no taxation in  the nature of inheritance tax or estate duty or
withholding tax applicable to us or to any holder of the ADSs and  ordinary shares. There are no other
taxes likely to be material to us levied  by the Government of the Cayman Islands except  for stamp
duties which may be applicable on instruments executed  in, or  after execution brought within, the
jurisdiction of the Cayman Islands. No stamp  duty is payable  in the  Cayman Islands  on the issue of
shares by, or any transfers of shares of,  Cayman Islands  companies (except those which  hold  interests
in land in the Cayman Islands). The  Cayman  Islands is not party  to  any double  tax treaties that are
applicable to any payments made to  or by our  company. There  are  no  exchange control regulations or
currency restrictions in the Cayman Islands.

Payments of dividends and capital in  respect of the ADSs  and ordinary  shares will not be subject

to taxation in the Cayman Islands and  no  withholding will  be  required on the payment  of a dividend or
capital to any holder of the ADSs or  ordinary shares,  as the case may be,  nor will  gains derived  from
the disposal of the ADSs or ordinary shares be subject to Cayman Islands income or  corporation tax.

People’s Republic of China Taxation

Under the EIT Law, an enterprise established outside of China with a ‘‘de facto  management

body’’ within China is considered a ‘‘resident enterprise,’’ which means  that it is  treated in a manner
similar to a Chinese enterprise for enterprise  income  tax purposes. Although the  implementation rules
of the EIT Law define ‘‘de facto management  body’’ as  a managing body that exercises  substantive  and
overall management and control over  the production  and  business, personnel, accounting books and
assets of an enterprise, the only official  guidance for this definition  currently  available is set forth in the
Notice Regarding the Determination of  Chinese-Controlled Offshore Incorporated Enterprise  as PRC
Tax  Resident Enterprises on the Basis of  De Facto Management Bodies,  or Circular  82, issued by the
State Administration of Taxation, which  provides  guidance on the  determination  of  the tax  residence
status of a Chinese-controlled offshore incorporated enterprise, defined as an  enterprise that is
incorporated under the laws of a foreign country or territory and  that has a PRC enterprise or
enterprise group as its primary controlling  shareholder. Although  BeiGene, Ltd.  does not have  a PRC
enterprise or enterprise group as our  primary controlling shareholder  and is therefore not a Chinese-
controlled offshore incorporated enterprise within the meaning of Circular  82, in the  absence of
guidance specifically applicable to us,  we  have  applied  the guidance set  forth  in Circular 82 to evaluate
the tax residence status of BeiGene,  Ltd.  and its subsidiaries  organized outside the PRC.

According to Circular 82, a Chinese-controlled  offshore incorporated enterprise will be regarded as

a PRC tax resident by virtue of having  a ‘‘de facto management  body’’ in  China and will be subject to
PRC enterprise income tax on its worldwide income only if all of the following criteria are  met:

(cid:129) the primary location of the enterprise’s senior executives of the day-to-day  operational

management and senior management departments performing  their duties is in the PRC;

(cid:129) decisions relating to the enterprise’s financial and human resource matters are  made or  are

subject to approval by organizations or personnel in the  PRC;

155

(cid:129) the enterprise’s primary assets, accounting books  and  records,  company seals, and board  and

shareholder meeting minutes are located or  maintained in the PRC;  and

(cid:129) 50% or more of voting board members or senior  executives habitually reside in the PRC.

Currently, some of the members of our management  team are located in China. However, we do

not believe that we meet all of the conditions  outlined in  the immediately preceding  paragraph.
BeiGene, Ltd. and its offshore subsidiaries are incorporated outside  the PRC. As a holding company,
our  key assets and records, including the  resolutions and meeting minutes  of  our  board of directors and
the resolutions and meeting minutes  of  our  shareholders, are located and  maintained  outside the  PRC.
However, we are not aware of any offshore holding companies with a corporate structure similar to
ours that has been deemed a PRC ‘‘resident enterprise’’ by the PRC tax authorities. Accordingly, we
believe that BeiGene, Ltd. and its offshore subsidiaries should not  be  treated as a ‘‘resident enterprise’’
for PRC tax purposes if the criteria for ‘‘de  facto management body’’ as set  forth  in Circular 82 were
deemed applicable to us. However, as  the tax residency  status of an enterprise is subject to
determination by the PRC tax authorities  and uncertainties remain  with respect  to  the interpretation of
the term ‘‘de facto management body’’ as  applicable to our offshore entities, we will continue to
monitor our tax status.

The implementation rules of the EIT  Law provide that, (1) if the enterprise that distributes

dividends is domiciled in the PRC or  (2) if gains are realized from  transferring equity  interests  of
enterprises domiciled in the PRC, then such dividends or capital gains  are treated as China-sourced
income. It is not clear how ‘‘domicile’’ may be interpreted under  the EIT Law, and  it may  be
interpreted as the  jurisdiction where  the enterprise  is a tax resident. Therefore, if we  are considered as
a PRC tax resident enterprise for PRC  tax purposes, any dividends we pay to our overseas  shareholders
or ADS holders as well as gains realized  by  such shareholders or ADS holders from  the transfer of our
shares or ADSs may be regarded as China-sourced  income. As a  result  dividends paid to non-PRC
resident  enterprise ADS holders or shareholders may be subject  to  PRC withholding  tax at a rate of up
to 10% (or 20% in the case of non-PRC individual  ADS holders or shareholders)  and gains  realized  by
non-PRC resident enterprise ADS holders or shareholders from the transfer of our ordinary shares  or
ADSs may be subject to PRC tax at  a  rate of  10% (or 20% in  the case of non-PRC  individual ADS
holders  or shareholders). It is also unclear whether, if we  are considered a PRC resident enterprise,
holders  of our shares or ADSs would be able to claim the  benefit of income tax treaties or agreements
entered into between China and other  countries or areas.

Item 7. Management’s Discussion and Analysis of Financial  Condition and  Results of Operations

You should read the following discussion and analysis of our financial condition and results of
operations together with ‘‘Item 6—Selected  Consolidated Financial  Data’’ and our  consolidated financial
statements and related notes appearing  elsewhere  in  this Annual Report. In addition  to historical
information, this discussion and analysis  contains forward-looking statements that involve risks, uncertainties
and assumptions. Our actual results may  differ materially from those  anticipated  in  these forward-looking
statements as a result of certain factors. We discuss factors  that  we believe  could cause or contribute to these
differences below and elsewhere in this report,  including those set  forth under ‘‘Part I—Item  1A—Risk
Factors’’ and under ‘‘Forward-Looking Statements and  Market Data’’ in  this  Annual Report.

Overview

We  are a globally focused, clinical-stage biopharmaceutical  company dedicated to becoming a
leader in the discovery and development of innovative, molecularly targeted and  immuno-oncology
drugs for the treatment of cancer. We  believe the next  generation of  cancer  treatment will utilize
therapeutics both as monotherapies and  in  combination to attack multiple underlying mechanisms of
cancer cell growth and survival. We further believe that  discovery of  next generation cancer therapies
requires new research tools. To that end, we  have developed a proprietary cancer biology platform that
addresses the importance of tumor-immune system interactions  and the value of primary biopsies in
developing new models to support our  drug  discovery effort.  Our strategy is  to  develop  a pipeline of
drug candidates with the potential to  be  best-in-class  monotherapies and also  important  components of
multiple-agent combination regimens.

We  have used our cancer biology platform to develop  four clinical-stage drug candidates that we
believe have the potential to be best-in-class or first-in-class.  In addition, we believe that each has  the
potential to be an important component  of a  drug combination addressing  major unmet medical needs.
Our clinical-stage drug candidates include  three molecularly targeted agents, BGB-3111,  BGB-290 and
BGB-283 and one immuno-oncology agent, BGB-A317.  BGB-3111 is  a  potent and highly  selective
small molecule inhibitor of BTK. BGB-290 is a  molecularly targeted, orally available, potent  and highly
selective inhibitor of PARP1 and PARP2.  BGB-283  is a small  molecule  inhibitor of  both  the monomer
and dimer forms of the RAF kinase.  For  each of our molecularly targeted  drug  candidates, we have
achieved proof-of-concept by demonstrating objective responses in the  defined patient populations.
BGB-3111 received orphan drug designation from the FDA, for CLL, MCL and  WM. Our clinical-
stage immuno-oncology agent, BGB-A317, is  an investigational  humanized monoclonal antibody against
the immune checkpoint receptor, PD-1. We have IND  Applications in effect  for our BTK, PD-1  and
PARP inhibitors with the FDA. We have  also  received  approval of our Clinical Trial  Applications for
each  of our four clinical-stage drug candidates from  the CFDA. In addition to our  clinical-stage drug
candidates, we have a robust pipeline  of  preclinical programs and are planning to advance one or  more
of these  programs  into the clinic in the  next 12 months. We  retain full global rights  for all of our
clinical and preclinical drug candidates  and programs.

Since our inception on October 28, 2010, our operations  have focused  on organizing and  staffing

our  company, business planning, raising  capital, establishing our intellectual property portfolio and
conducting preclinical studies and clinical  trials. We do not have any drug  candidates approved for  sale
and have not generated any revenue from  product  sales. We have financed operations through a
combination of public and private equity  and  debt financings and public and private grants and
contracts, including the net proceeds from  our  initial public offering and follow-on public  offering, the
net proceeds from the issuance of a  senior note and convertible  promissory note to Merck Sharp &
Dohme Research GmbH, or MSD, an affiliate of Merck Sharp & Dohme Corp., the private placements
of our Series  A preferred shares and Series A-2  preferred shares, and our collaboration with
Merck KGaA, Darmstadt Germany,  or Merck KGaA,  Darmstadt  Germany Collaboration. On
February 8, 2016 and November 23, 2016, we completed  our initial public offering and  follow-on public

159

offering, and received net proceeds of $166.2 million  and  $198.6  million,  respectively, after  deducting
underwriting discounts and offering expenses. Although it  is difficult to predict our liquidity
requirements, based upon our current  operating  plan and the successful completion of our initial public
offering and follow-on public offerings,  we  believe we have sufficient cash  to  meet our  projected
operating requirements for at least the next 12  months. See ‘‘—Liquidity and Capital Resources.’’

Since inception we have incurred significant operating losses. Our  net losses  were $119.2  million,

$57.1 million and $18.5 million for the  years ended December 31, 2016,  2015 and 2014, respectively. As
of December 31, 2016, we had an accumulated deficit  of  $237.4 million. In the future,  we may  generate
revenue from product sales, collaboration agreements,  strategic alliances and licensing arrangements, or
a combination of these. Substantially  all of our  losses have resulted from funding our research and
development programs and general and administrative costs associated with our operations. We  expect
to continue to incur significant expenses  and  operating losses for the foreseeable future. We anticipate
that our expenses will increase significantly  in connection  with our ongoing activities,  as we:

(cid:129) continue investment in our cancer  biology platform;

(cid:129) continue preclinical and clinical development of our  programs;

(cid:129) continue investment in our manufacturing facilities;

(cid:129) hire additional research, development and business personnel;

(cid:129) maintain, expand and protect our intellectual property  portfolio; and

(cid:129) incur additional costs associated with operating as a public company.

We  expect that any revenue we generate 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 drug candidates in a  timely manner or obtain regulatory  approval of
them, our ability to generate future revenue, and our  results of operations and financial position, would
be materially adversely affected.

Cash used in operations were $89.5 million, $39.8 million and $8.7  million, respectively, for  years
ended December 31, 2016, 2015 and 2014. As  of  December 31,  2016, we had  cash, cash equivalents and
short-term investments of $368.2 million, compared with $100.5 million as  of  December 31, 2015.

Financial Operations Overview

Revenue

To date, our revenue has consisted of upfront  license fees,  reimbursed research and  development

expenses and milestone payments from our collaboration  agreements with  Merck KGaA,  Darmstadt
Germany on BGB-283 and BGB-290. We have not generated any revenue from product sales and  do
not expect to generate any revenue from  product  sales  for the  foreseeable  future.

On May 24, 2013, we entered into license  agreements with Merck KGaA, Darmstadt  Germany on
BGB-283, which we amended and restated on December 10, 2013, and further  amended on October 1,
2015 and December 3, 2015. In the latest  amendment,  Merck KGaA, Darmstadt Germany granted  us
an exclusive license under certain of  its  intellectual property rights to develop, manufacture and
commercialize the RAF dimer inhibitor  in The People’s Republic of  China, which we  refer  to  as the
PRC Territory, subject to certain non-compete restrictions.  In  March 2017,  Merck KGaA,  Darmstadt
Germany informed us that it will not  exercise the  Continuation Option in the  ex-PRC  Territory, and
thus,  the ex-PRC BRAF Agreement has terminated in its entirety, except for certain provisions that will
survive the termination. Under these  agreements, we received $13 million in  non-refundable payments
in 2013 following their execution, $5 million in milestone  payments in  2014 and $4 million  in milestone

160

payments in 2015.  We are eligible to  receive $14 million in payments  upon  the successful achievement
of pre-specified clinical milestones in  the PRC Territory. In consideration for the licenses Merck KGaA,
Darmstadt Germany grants to us, we  were required to pay Merck  KGaA, Darmstadt Germany  a high
single-digit royalty on aggregate net sales of licensed BRAF  inhibitors in the PRC Territory.

On October 28, 2013, we entered into  license agreements  with Merck KGaA,  Darmstadt Germany

on BGB-290, pursuant to which (1) we granted  to  Merck KGaA, Darmstadt Germany an  exclusive
license under certain of our intellectual  property rights  to  develop  and manufacture,  and, if Merck
KGaA, Darmstadt Germany exercises  a  certain continuation option,  to  commercialize and manufacture
our  compound BGB-290 and any other compound covered by the same existing patent rights  with
primary activity to inhibit PARP 1, 2 or  3 enzymes in the  Ex-PRC Territory, and  (2) Merck KGaA,
Darmstadt Germany granted us an exclusive  license under certain of its intellectual property rights  to
develop, manufacture and commercialize  the licensed PARP inhibitors in  the PRC Territory.  Under
these license agreements, we received $6  million in  non-refundable payments in November 2013
following their execution and $9 million  in milestone payments in 2014. We are eligible to receive up to
$7 million and $2.5 million, in payments upon  the successful achievement of pre-specified clinical  and
regulatory milestones in the PRC Territory respectively.  On October 1, 2015,  pursuant to a purchase of
rights agreement, we repurchased all  of Merck KGaA, Darmstadt Germany’s worldwide rights under
the ex-PRC license agreement, in consideration  for,  among  other things, a one-time payment of
$10 million and reduction of future milestone  payments that  we are  eligible to receive under the PRC
license agreement. In connection with such repurchase,  the ex-PRC license agreement terminated
except for certain provisions therein. The remaining $3 million of  deferred revenue  related to PARP as
of October 1, 2015 was netted against  the  $10 million repurchase  consideration.  In  addition, if Merck
KGaA, Darmstadt Germany exercises  its  PRC commercialization option, Merck  KGaA, Darmstadt
Germany is required to pay us a $50 million non-refundable payment upon such  exercise,  and we are
eligible for a $12.5 million milestone payment upon the successful  achievement of a  certain additional
regulatory event in the PRC Territory.  In  consideration for the  licenses granted  to  us,  we are  required
to pay Merck KGaA, Darmstadt Germany a  high single-digit royalty  on  aggregate  net sales of licensed
products in the PRC Territory.

For more information on our collaborations with Merck KGaA, Darmstadt Germany, see  ‘‘Part I—

Item 1—Business—Collaboration with Merck KGaA, Darmstadt Germany.’’

We  recognized $1.1 million, $8.8 million and $13.0 million of  collaboration  revenue from  the
Merck KGaA, Darmstadt Germany Collaboration  for the  years  ended December  31, 2016, 2015 and
2014, respectively. The following table  summarizes  the revenue recognition  schedule  of  an aggregate of
$34.0 million in revenue from our collaboration  agreements with  Merck  KGaA, Darmstadt Germany,
comprised of an aggregate of $22.0 million related to BGB-283 and $12.0 million  related to BGB-290.
The revenue consists of an upfront non-refundable license fee, Phase 1 research and development  fees,
and a development based target payment  related to the collaborative arrangements for  BRAF,
excluding the $3 million in deferred  revenue that was  netted against  the $10  million repurchase
consideration relating to the PARP inhibitors under the ex-PRC license agreement. In accordance with
our  revenue recognition policy, we have  recognized these  amounts  as shown  in the table below:

For the years ended December 31, 2016,  2015 and 2014, substantially all of  our revenue were

generated solely from Merck KGaA,  Darmstadt  Germany. For the foreseeable  future, we expect
substantially all of our revenue will be generated  from the Merck KGaA,  Darmstadt  Germany
Collaboration, and any other strategic  relationships we may enter into.  If our development efforts  are
successful, we may also generate revenue  from product sales.

Operating Expenses

Research and Development Expenses

Research and development expenses consist of the costs associated with our  research  and
development activities, conducting preclinical studies and clinical trials and activities  related to
regulatory filings. Our research and development expenses  consist of:

(cid:129) employee-related expenses, including salaries, benefits, travel and share-based  compensation

expense for research and development personnel;

(cid:129) expenses incurred under agreements with contract research organizations, or CROs, contract
manufacturing organizations, and consultants that conduct and support clinical trials and
preclinical studies;

(cid:129) costs associated with preclinical activities and development activities;

(cid:129) costs associated with regulatory operations; and

(cid:129) other expenses, which include direct and  allocated  expenses for rent and maintenance of

facilities, insurance and other supplies used in research and development activities.

Our current research and development activities mainly  relate to the clinical development of  the

following programs:

(cid:129) BGB-3111, a potent and highly selective small molecule inhibitor of BTK;

(cid:129) BGB-A317, an investigational humanized monoclonal  antibody against  PD-1;

(cid:129) BGB-290, a molecularly targeted, orally  available,  potent and  highly selective  inhibitor of  PARP1

and PARP2; and

(cid:129) BGB-283, a small molecule inhibitor of both the  monomer  and  dimer forms of BRAF.

We  expense research and development  costs when we incur them. We record costs for some
development activities, such as clinical  trials,  based on  an evaluation  of the progress to completion of
specific  tasks using data such as subject  enrollment, clinical site activations  or information  our  vendors
provide to us. We do not allocate employee-related costs, depreciation, rental and  other indirect  costs
to specific research and development  programs because these costs are deployed across multiple
product  programs  under research and  development and, as such, are separately classified as  unallocated
research and development expenses.

At this time, we cannot reasonably estimate or know the nature, timing  and estimated  costs of the
efforts that will be necessary to complete  the development  of  our drug candidates. We  are also  unable
to predict when, if ever, material net cash  inflows will commence from sales of  our drug  candidates.
This is due to the  numerous risks and  uncertainties associated  with developing such drug candidates,
including the uncertainty of:

(cid:129) successful enrollment in and completion of clinical trials;

(cid:129) establishing an appropriate safety profile;

162

(cid:129) establishing commercial manufacturing capabilities or making arrangements with third-party

manufacturers;

(cid:129) receipt of marketing approvals from applicable  regulatory authorities;

(cid:129) commercializing our drug candidates, if and  when approved, whether  as monotherapies  or in

combination with our internally discovered  drug candidates or third-party agents;

(cid:129) obtaining and maintaining patent and trade  secret  protection and regulatory  exclusivity for our

drug candidates;

(cid:129) continued acceptable safety profiles of  the products following approval; and

(cid:129) retention of key research and development personnel.

A change in the outcome of any of these variables with respect  to  the  development of any of our

drug candidates would significantly change the costs,  timing and viability associated with the
development of that drug candidate.

Research and development activities  are central to our business  model.  We expect research and
development costs to increase significantly for the foreseeable future as our development  programs
progress, including as we continue to  support the  clinical trials  of  BGB-3111, BGB-A317, BGB-290 and
BGB-283 as a treatment for various  cancers  and move  these  drug candidates into additional  clinical
trials. There are numerous factors associated with the successful  commercialization of any of our drug
candidates, including future trial design  and various  regulatory requirements, many of which cannot be
determined with accuracy at this time based on our stage of development.  Additionally, future
commercial and regulatory factors beyond our control will impact our clinical  development programs
and plans.

General and Administrative Expenses

General and administrative expenses  consist primarily of salaries  and  related benefit costs,

including share-based compensation  for general  and administrative personnel. Other  general and
administrative expenses include professional fees for legal,  consulting,  auditing and tax services as well
as other direct and allocated expenses  for  rent and maintenance of facilities, insurance and other
supplies used in general and administrative  activities. We anticipate  that our  general and administrative
expenses will increase in future periods to support  increases in  our research  and development  activities,
including the continuation of the clinical trials of BGB-3111, BGB-A317, BGB-290  and BGB-283 as a
treatment for various cancers and the initiation of  our clinical trials  for our other drug  candidates.
These cost increases will likely be due to increased headcount,  increased  share-based compensation
charges, expanded infrastructure and increased costs for insurance. We also anticipate increased legal,
compliance, accounting and investor  and  public relations expenses associated with being a  public
company.

Interest Income (Expense), Net

Interest Income

Interest income consists primarily of interest  generated from our short-term  investments in

treasury securities, municipal bonds and  corporate fixed income  bonds.

Interest Expense

Interest expense consists primarily of interest on our  senior promissory note, convertible

promissory note and long-term bank  loan.

163

In 2011, we issued a $10 million, 8%  senior  promissory note  and a $10 million 8% subordinated

convertible promissory note, compounded annually, each to MSD.  We also  issued an aggregate
principal amount of $3.1 million convertible promissory  notes to several other investors  in 2012 and
2014, all bearing interest of 8% per annum  for the  first  three years and 15% per annum  for the
remaining term. In October 2014, we completed a  Series A  preferred share financing,  as a result  of
which,  the $10 million MSD subordinated  convertible promissory note  was automatically  converted  into
18,518,519 Series A preferred shares,  and the other $3.1  million  principal  amount  of convertible
promissory notes, along with accrued interest was  automatically converted into 5,470,705 Series A
preferred shares. We recognized a gain on  debt extinguishment of $2.9 million due to the  forfeiture of
interest upon the conversion, as only  the principal  amount  of the Merck subordinated  convertible
promissory note was eligible for conversion. In February 2016, in connection with the closing of our
initial public offering, the outstanding  unpaid  principal  and interest of the MSD Senior Promissory
Note was automatically exchanged into 7,942,314 of our ordinary shares.

On September 2, 2015, BeiGene (Suzhou) Co.,  Limited,  or  BeiGene  Suzhou,  entered into a loan
agreement with Suzhou Industrial Park  Biotech Development Co.,  Ltd.  and  China Construction Bank,
to borrow $17.3 million at a 7% fixed annual interest rate. As of  December 31, 2016, we have drawn
down $17.3 million, which is secured by BeiGene Suzhou’s equipment with a carrying  amount  of
$22.3 million and our rights to a PRC  patent on a drug candidate. The loan amounts of  $8.7 million
and $8.6 million are repayable on September 30, 2018  and  2019, respectively.

Other Income, Net

Other income consists primarily of government grants received  that involve no conditions  or
continuing performance obligations by  us. Other expense consists primarily of loss from property and
equipment disposals and donations made  to  sponsor certain events.

Revenue

Revenue from the Merck KGaA, Darmstadt Germany Collaboration decreased by $7.7 million to
$1.1 million for the year ended December 31, 2016  from $8.8 million for the year ended  December 31,
2015. The decrease was primarily attributable to decrease of  revenue recognized for BGB-283  and
revenue that was no longer being recognized  for BGB-290 in  2016 after we repurchased the ex-PRC
right from Merck KGaA, Darmstadt  Germany in October 2015.

Research and Development Expense

Research and development expense increased by $39.7 million to $98.0 million  for the  year  ended

December 31, 2016 from $58.3 million  for  the year  ended December  31, 2015.  The following  table
summarizes our external clinical, external preclinical and internal research and development expense

$8.8 million for the year ended December 31, 2015  from $13.0 million for the year ended
December 31, 2014. The decrease was mainly attributable to the difference between revenues
recognized in 2014 for payments received  for  dosing  of 5th  patient  of  BGB-283 and BGB-290 in
ex-PRC trials and a payment received in 2015 for dosing of  the  5th patient of  BGB-283  in PRC trials.

$21,862

The increase in external research and  development expense was primarily attributable to the

advancement of our clinical and preclinical pipeline, and included the following:

(cid:129) Increases of approximately $7.8 million, $5.8 million, $6.4  million, and $0.7  million  respectively

for BGB-290, BGB-A317, BGB-3111, and  BGB-283, including the recognized expenses
associated with the repurchase of ex-PRC rights to BGB-290.

167

The increase in internal research and development  expense was primarily attributable to the

expansion of our development organization and our pipeline, and included  the following:

(cid:129) $7.7 million for increased compensation  expenses, which was primarily attributable to the hiring
of more development personnel during the  year  ended December 31, 2015 and increased share
option expense ($9.6 million in 2015  increased  from $4.0 million in 2014); and

(cid:129) $4.7 million for increased facilities,  reagents, consulting fee and other expenses.

General and Administrative Expense

General and administrative expense increased by $0.4  million  to  $7.3 million  for the  year  ended

December 31, 2015 from $6.9 million  for  the year  ended December  31, 2014.  The  increase was
primarily attributable to the following:

(cid:129) $0.7 million increase of professional fees, in connection  with the Series A-2 preferred share

financing and initial public offering;

(cid:129) $0.9 million increase of employee salary and benefits,  which was  primarily attributable to hiring

of more personnel during the year ended  December 31,  2015;

(cid:129) $2.0 million decrease in stock option  expense ($0.6 million in 2015 compared to $2.6  million  in

2014) primarily attributable to the contractual discount in the exchange price  of a loan advanced
by a senior executive to the company into Series A  preferred  shares which was treated as  a
compensation expense in 2014; and

(cid:129) $0.8 million increase of travel, office, leasing and other administrative expenses,  mainly in

connection with the global expansion of the  company.

Interest Income (Expense), Net

Interest expense (net) decreased by $4.1 million from  $3.5 million  for  the year  ended

December 31, 2014, resulting in net interest income of $0.6  million  for the  year  ended December  31,
2015. The decrease in interest expense was  primarily attributable to the decrease in interest  expenses
following conversion of the subordinated  convertible  promissory  note and convertible promissory notes
in the Series A preferred share financing,  offset by the  interest income  attributable  to  short-term
investments municipal bonds and corporate fixed income bonds.

Changes in Fair Value of Financial Instruments

Loss from changes in fair value of financial instruments  decreased by $1.0  million to $1.8 million
for the year ended December 31, 2015  from $2.8 million for the year ended  December 31,  2014. The
decrease in loss from change in fair value  of  financial instruments was  primarily  attributable  to  changes
in fair value of the redemption feature  bifurcated  from the MSD subordinated convertible  promissory
note of $2.5 million recorded in the year  ended December 31, 2014  before conversion to Series A
preferred shares in October 2014, offset by  the fair value  increase of our  ordinary shares underlying the
warrants and option we issued.

Loss  on Sale of Available-for-Sale Securities

The $0.3 million loss on sale of available-for-sale securities  was  recorded for  the year  ended

December 31, 2015 following the sale  of  certain  available-for-sale securities.

168

Gain on Debt Extinguishment

The $2.9 million gain on debt extinguishment recorded  for the  year ended December  31, 2014

resulted from forfeiture of interest of the  MSD subordinated convertible  promissory  note upon
automatic conversion of the note in October  2014.

Other Income, Net

Other income increased by $0.6 million  to  $1.2 million for the year ended December 31, 2015 from

$0.6 million for the year ended December 31, 2014.  Other  income primarily  consisted of government
grants received and foreign exchange gains recognized.

Liquidity and Capital Resources

Since inception, we have incurred net losses and  negative cash flows from our operations.

Substantially all of our losses have resulted from  funding  our research and  development programs and
general and administrative costs associated with our operations. We  incurred  net losses of
$119.2 million, $57.1 million and $18.5  million for the years ended December 31,  2016, 2015 and 2014,
respectively. As of December 31, 2016, we had an accumulated deficit of  $237.4 million. Our primary
use of cash is to fund research and development costs. Our operating activities used  $89.5 million,
$39.8 million and $8.7 million of cash flows during the years ended December 31,  2016, 2015 and 2014,
respectively. Historically, we financed  our  operations principally through  proceeds from  private
placements of preferred shares, promissory  notes and convertible  notes of $184.4  million  and proceeds
from the Merck KGaA, Darmstadt Germany  Collaboration of  $37.0 million.  On February  8, 2016 and
November 23, 2016, we completed our  initial public offering and follow-on public offering as follows:

On February 8, 2016, we completed our initial public offering, or IPO, on the NASDAQ Global
Select Market. 6,600,000 ADSs representing 85,800,000  ordinary shares were sold at  $24.00 per ADS,
or $1.85 per share. Additionally, the underwriters exercised their options to purchase an  additional
990,000 ADSs representing 12,870,000 ordinary shares. Net proceeds from  the IPO including
underwriter options after deducting underwriting discount and offering  expenses were $166.2 million.
The deferred IPO costs of $16.0 million  were recorded as  a  reduction  of the proceeds received  from
the IPO in the shareholders’ equity.

On November 23, 2016, we completed  a follow-on public  offering  at  a  price of $32.00  per  ADSs,
or $2.46 per share. In this offering, we sold 5,781,250  ADSs representing 75,156,250  ordinary shares.
Additionally, the underwriters exercised their options to purchase an additional 850,000 ADSs
representing 11,050,000 ordinary shares  from us. The selling shareholders sold 468,750 ADSs
representing 6,093,750 ordinary shares.  Net proceeds  from this offering  including underwriter options
after deducting the underwriting discount and offering expenses were  $198.6 million. We did  not
receive any proceeds from the sale of the shares by the selling shareholders. The  deferred follow-on
public offering costs of $13.6 million were  recorded  as a reduction of the proceeds received from the
offering in shareholders’ equity.

Net Cash Used in Operating Activities

The use of cash in all periods presented resulted primarily  from our net losses  adjusted for
non-cash charges and changes in components of working capital.  The  primary  use of our cash in all
periods presented was to fund the development of our research and development,  regulatory and other
clinical trial costs, and related supporting administration. Our  prepaid  expenses and other current
assets, accounts payable and accrued  expense  balances  in all periods presented were  affected by the
timing of  vendor invoicing and payments.

During  the year ended December 31,  2016,  operating activities used $89.5 million of cash, which

resulted principally from our net loss  of $119.2 million, adjusting for  non-cash charges of $15.5 million
and interest expense of $0.1 million, and by cash provided in our  operating assets and  liabilities of
$14.1 million. Our net non-cash charges  during  the year ended December 31, 2016  primarily  consisted

Net Cash Used in Investing Activities

Net cash used in investing activities was $221.8 million for the year ended  December 31,  2016

compared to $58.9 million for the year  ended December 31, 2015.  The  increase in cash used in
investing activities was primarily due  to  $198.4 million net  purchase  of available-for-sale securities  and
$23.5 million paid to purchase property  and equipment.

Net cash used in investing activities was $58.9 million for the year ended  December 31,  2015

compared to $33.6 million for the year  ended December 31, 2014.  The  increase in cash used in

170

investing activities was primarily due  to  a net  purchase  of $53.6 million worth of  short-term investments
and $5.3 million paid to purchase property and equipment.

Net Cash Provided by Financing Activities

Net cash provided by financing activities was  $380.9 million  for  the year ended December 31, 2016

compared to $103.2 million for the year  ended December 31, 2015.The increase  was  primarily  due  to
proceeds of $366.7 million from our  initial and follow-on public offerings, net  of  offering costs,
long-term loan proceeds of $12.0 million from  Suzhou  Industrial  Park  Biotech  Development Co., Ltd.
and China Construction Bank and proceeds of $2.2 million from the exercise  of  warrants and options.

Net cash provided by financing activities was  $103.2 million  for  the year ended December 31, 2015

compared to $52.2 million for the year  ended December 31, 2014.  The  increase was primarily due to
the issuance of $97.4 million Series A-2 preferred shares to  certain investors and long-term loan
proceeds of $6.2 million from Suzhou  Industrial Park  Biotech Development  Co.,  Ltd. and  China
Construction  Bank.

Operating Capital Requirements

We  do not expect to generate significant  revenue from product sales unless  and until  we obtain

regulatory approval of and commercialize one of  our current or  future drug candidates.  We anticipate
that we will continue to generate losses  for the foreseeable future, and we expect the losses  to  increase
as we continue the development of, and seek regulatory  approvals for, our drug candidates  and begin
to commercialize any approved products.  As  a newly public company, we  will  incur  additional costs
associated with operating as a public company. In addition,  subject to obtaining regulatory  approval of
any of our drug candidates, we expect  to  incur significant commercialization expenses  for product sales,
marketing and manufacturing. Accordingly, we anticipate  that we will  need substantial additional
funding in connection with our continuing operations.

Based on our current operating plan,  we expect  that our  existing cash, cash  equivalents and
short-term investments as of December 31, 2016,  will enable us to fund our operating  expenses and
capital expenditures requirements for at least the next  15 months. We  expect  that  our expenses will
continue to increase substantially as we fund clinical  development of BGB-3111, BGB-A317,  BGB-290
and BGB-283, fund new and ongoing  research and development activities  and working capital and
other general corporate purposes. We  have based our estimates on  assumptions that may  prove to be
wrong, and we may use our available capital resources sooner than we currently expect.  Because of the
numerous risks and uncertainties associated with the development and commercialization  of  our  drug
candidates, we are unable to estimate  the amounts  of  increased  capital  outlays and  operating
expenditures necessary to complete the  development and  commercialization of our drug candidates.

Our future capital requirements will depend on many  factors, including:

(cid:129) the costs, timing and outcome of regulatory  reviews and approvals;

(cid:129) the ability of our drug candidates to  progress through clinical development successfully;

(cid:129) the initiation, progress, timings, costs and results  of nonclinical studies and clinical trials for our

other programs and potential drug candidates;

(cid:129) the number and characteristics of the drug candidate we pursue;

(cid:129) the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing  our

intellectual property rights and defending  intellectual property-related claims;

(cid:129) the extent to which we acquire or  in-license  other products and  technologies; and

(cid:129) our ability to maintain and establish collaboration arrangements  on  favorable terms,  if  at all.

171

Until such time, if ever, as we can generate  substantial product revenue,  we expect to finance  our

cash needs through a combination of equity  offerings,  debt  financings, collaborations, strategic alliances,
licensing arrangements and government grants. To the extent  that we raise additional  capital through
the sale of equity or convertible debt securities, the  ownership  interest of our shareholders will be
diluted, and the terms of these securities may include liquidation  or other preferences that adversely
affect your rights as an ADS holder.  Debt financing, if available,  may  involve  agreements that include
covenants limiting or restricting our ability to take specific actions, such as incurring additional debt,
making capital expenditures or declaring  dividends and may require the issuance of warrants, which
could potentially dilute your ownership interest.  If we raise  additional funds through collaborations,
strategic alliances or licensing arrangements with  third  parties, we may have to relinquish valuable
rights to our technologies, future revenue streams  or research programs or to grant  licenses on terms
that may not be favorable to us. If we are unable to raise additional funds through  equity or debt
financings when needed, we may be required to delay,  limit, reduce or  terminate  our  product
development or future commercialization efforts or grant  rights to develop and market products  or
drug candidates that we would otherwise prefer to develop  and  market  ourselves.

Operating Lease Commitments

We  lease office and manufacturing facilities in Beijing and Suzhou,  PRC under non-cancelable

operating leases expiring on different dates. Payments under operating  leases are expensed  on a
straight-line basis over the periods of the  respective leases, and the terms of the  leases do not contain
rent escalation, contingent rent, renewal  or  purchase  options.  The  future minimum payments  under
these non-cancelable operating leases are summarized  in the table above. In addition, we  lease office
facilities in the Greater Boston area,  California and New Jersey, United  States.

On April 10, 2016, we entered into a  Lease Agreement with Suzhou Industrial Park Biotech

Development Co., Ltd. for an approximately 11,000 square meter  facility for research and
manufacturing use in Suzhou, China. The lease  commenced  on April  18, 2016 and will expire  on
July 17, 2021. The initial rent, the payment  of  which commenced on  July  18,  2016, is  RMB 280,650 per
month, plus service charges of RMB 65,485  per  month and other fees for use of  the premises, including
water costs and electricity. The service  charges will  remain  unchanged  for  the first three years and the
increasing range thereafter will not exceed 5%  of  the previous  yearly service charges.  Suzhou  Industrial
Park Administrative Committee will  pay  our full monthly  rent  for  the first three years and 50% of  the
monthly rent for the following two years.  The  lease contains  customary covenants, insurance and
indemnification obligations, and termination provisions.

172

Long-term Debt Obligation

On September 2, 2015, BeiGene Suzhou entered into a loan agreement with Suzhou Industrial
Park Biotech Development Co., Ltd. and China  Construction Bank,  to  borrow $17.3 million  at a  7%
fixed annual interest rate. As of December  31, 2016, we have  drawn down  $17.3 million, which is
secured by BeiGene Suzhou’s equipment  with a carrying  amount  of  $22.3 million and our rights to a
PRC patent on a drug candidate. The loan amounts  of  $8.7 million and $8.6 million are repayable on
September 30, 2018 and 2019, respectively.

Capital Commitments

We  had capital commitments amounting to $4.5 million for the acquisition of property,  plant  and

equipment as of December 31, 2016, which  was  primarily for building BeiGene  Suzhou’s manufacturing
facility in Suzhou, China.

Other  Business Agreements

We  enter into agreements in the normal course of business with CROs and institutions to license

intellectual property. We have not included  these future payments in the table  of  contractual
obligations above since the contracts are cancelable  at any time  by us  with prior  written  notice.

Off-Balance Sheet Arrangements

We  did not have during the periods presented, and we do  not currently  have,  any off-balance sheet

arrangements, as defined under SEC rules, such as relationships with  unconsolidated entities or
financial partnerships, which are often referred to as  structured  finance  or special  purpose entities,
established for the purpose of facilitating financing transactions that  are  not required  to  be  reflected on
our  balance sheets.

Critical Accounting Policies and Significant  Judgments and  Estimates

Our discussion and analysis of our financial condition and results of  operations is  based on our

financial statements, which have been  prepared in  accordance with accounting  principles  generally
accepted in the United States of America, or GAAP. The preparation  of these  financial  statements
requires us to make estimates and assumptions that affect the reported amounts  of  assets, liabilities and
the disclosure of contingent assets and liabilities at  the date  of  our financial statements and the
reported amounts of revenues and expenses during  the periods.  We evaluate our  estimates and
judgments on an ongoing basis, including  but not limited to, estimating the  useful lives  of  long-lived
assets, identifying separate accounting units and estimating the best  estimate selling price  of  each
deliverable in our revenue arrangements, assessing the  impairment of long-lived assets, share-based
compensation expenses, realizability of  deferred tax  assets and  the fair value  of  warrant and option
liabilities. We base our estimates on historical experience, known trends  and events, contractual
milestones and other various factors that are believed  to  be reasonable under  the circumstances, the
results of which form the basis for making  judgments about the carrying values  of assets and liabilities
that are not readily apparent from other  sources.  Our actual results may  differ  from these estimates
under different assumptions or conditions.

We  believe the following critical accounting policies reflect our more significant estimates  and

assumptions used in the preparation  of our financial statements.

Revenue Recognition

We  recognize revenues from research  and development  collaborative arrangements when

persuasive evidence of an arrangement  exists, delivery has occurred or services  have been rendered, the

173

fee is fixed or determinable, and there is  reasonable assurance  that the related  amounts  are collectible
in accordance with ASC 605, Revenue Recognition, or ASC 605. Our collaborative arrangements may
contain multiple elements, including  grants of licenses  to  intellectual property rights,  agreement to
provide research and development services  and  other deliverables. The deliverables under such
arrangements are evaluated under ASC  605-25, Multiple-Element Arrangements. Pursuant to
ASC 605-25, each required deliverable  is  evaluated to determine whether it qualifies as a separate unit
of accounting based on whether the deliverable  has ‘‘stand-alone value’’ to the customer. The
collaborative arrangements do not include a right of return for  any deliverable.  The arrangement’s
consideration that is fixed or determinable, excluding  contingent payments, is then  allocated  to  each
separate unit of accounting based on  the relative selling price  of  each deliverable. The relative selling
price for each deliverable is determined using  vendor  specific objective evidence, or VSOE,  of  selling
price or third-party evidence, or TPE, of  selling price  if VSOE  does not exist.  If neither VSOE  nor
TPE exists, we use the best estimate  of the selling price, or BESP,  for the  deliverable. In general,  the
consideration allocated to each unit of  accounting  is recognized as the related  goods or services are
delivered, limited to the consideration  that  is not contingent upon  future deliverables. Non-refundable
payments received before all of the relevant criteria for  revenue recognition are satisfied  are recorded
as advances from customers.

Upfront non-refundable payments for  licensing our intellectual property are evaluated to

determine if the licensee can obtain stand-alone value  from the license separate from the  value of  the
research and development services and  other deliverables in  the arrangement to be provided by us. We
act as the principal under our arrangements and licensing intellectual  property  is part of our ongoing
major or central operations. The license  right is not contingent  upon the  delivery of additional items  or
meeting  other specified performance  conditions.  Therefore, when stand-alone value  of  the license  is
determinable, the allocated consideration is  recognized  as collaboration  revenue upon delivery of  the
license rights.

As we act as the principal under our arrangements, and research and development services are
also part of our ongoing major or central  operations, we recognize the allocated consideration  related
to reimbursements of research and development costs  as collaboration revenue when delivery or
performance of such services occurs.

Product development, royalties and commercial event payments, collectively referred  to  as target

payments, under collaborative arrangements are triggered either  by the results  of our  research  and
development efforts, achievement of regulatory goals or by specified  sales  results by a  third-party
collaborator. Under ASC 605-28, Milestone Method of Revenue Recognition, an accounting policy
election can be made to recognize a payment that is contingent upon the achievement  of a substantive
milestone in its entirety in the period in  which  the milestone is achieved. We  elected  not  to  adopt the
milestone method of revenue recognition under  ASC 605-28.

Targets  related to our development-based activities may include  initiation of various phases of
clinical trials and applications and acceptance for product approvals by  regulatory agencies. Due  to  the
uncertainty involved in meeting these  development-based targets, we would account for development-
based targets as collaboration revenue  upon achievement  of the  respective development target.
Royalties based on reported sales of  licensed products will  be recognized as collaboration  revenue
based on contract terms when reported sales are  reliably  measurable and  collectability  is reasonably
assured. Targets related to commercial activities may be triggered  upon events such as  first  commercial
sale of a product or when sales first achieve a  defined level.  Since these targets would be achieved after
the completion of our development activities, we would  account for the commercial  event targets in  the
same manner as royalties, with collaboration revenue recognized upon achievement  of  the target. To
date,  none of the products have been  approved. Hence,  no revenue  has been recognized related to
royalties or commercial event based targets in  any  of  the periods presented.

174

Any subsequent payments to be made to the collaborator such as profit sharing payments  based on
net sales that are not related to research  and development services would  be  recorded as expenses from
the collaborative arrangement. To date, no payments have been  made to the  collaborator.

Research and Development Expenses

Research and development expenses represent  costs associated  with the collaborative
arrangements, which primarily include  (1)  payroll and related costs (including share-based
compensation) associated with research and development  personnel; (2) costs related to clinical  trials
and preclinical testing of our technologies under development; (3) costs to develop the product
candidates, including raw materials and  supplies, product testing, depreciation, and facility  related
expenses; (4) expenses for research services provided by universities  and  contract laboratories, including
sponsored research funding; and (5) other research and development expenses. Research and
development expenses are charged to expense as incurred when  these expenditures relate to our
research and development services and  have no  alternative future  uses.

Clinical trial costs are a significant component of our research and development expenses. We have

a history of contracting with third parties that perform various  clinical trial  activities on behalf of us in
the ongoing development of our product candidates. Expenses  related to clinical trials are  accrued
based on our estimates of the actual services performed by the  third parties for  the respective period. If
the contracted amounts are modified (for instance,  as a result of changes in  the clinical  trial protocol
or scope of work to be performed), we  will modify  the related accruals  accordingly  on a  prospective
basis. Revisions in the scope of a contract  are  charged to expense  in the period in which  the facts  that
give rise  to the revision become reasonably certain.

The process of estimating our research and development expenses involves reviewing open
contracts and purchase orders, communicating  with our personnel to identify  services  that  have been
performed on our behalf and estimating the  level of service performed  and the associated costs
incurred for the services when we have not yet been  invoiced or otherwise notified  of the actual costs.
The majority of our service providers  invoice us  in arrears for services performed,  on a  pre-determined
schedule or when contractual milestones are met;  however, some require advanced payments.  We make
estimates of our expenses as of each balance sheet date  in our  financial statements based  on facts and
circumstances known to us at that time. Although we do not expect our  estimates to be materially
different from amounts actually incurred,  our understanding of the status and timing of services
performed relative to the actual status  and  timing  of services performed  may vary and  may result in us
reporting expenses that are too high or  too  low in any particular period. To  date, we have not made
any material adjustments to our prior  estimates  of research and  development expenses.

Share-Based Compensation

Awards Granted to Employees

We  apply ASC 718,  Compensation—Stock Compensation, or ASC 718, to account for our employee

share-based payments. In accordance  with ASC  718, we determine  whether an award should be
classified and accounted for as a liability award  or equity award. All  our grants of share-based awards
to employees were classified as equity  awards and  are recognized in the  financial  statements  based on
their grant date fair values. We have elected to recognize compensation expense using the straight-line
method for all employee equity awards  granted with  graded vesting based on service conditions
provided that the amount of compensation cost  recognized at any date  is at least  equal to the portion
of the grant-date value of the options that  are vested at  that  date. We use  the accelerated  method for
all awards granted with graded vesting based on performance conditions. To  the extent the required
vesting conditions are not met resulting  in the forfeiture of the share-based awards, previously
recognized compensation expense relating to those awards are reversed. ASC 718 requires forfeitures to

175

be estimated at the time of grant and  revised, if necessary, in the subsequent  period if actual  forfeitures
differ  from initial estimates.

Forfeiture rates are estimated based  on historical and future expectations of employee turnover

rates and are adjusted to reflect future changes  in circumstances  and facts, if any.  Share-based
compensation expense is recorded net of  estimated  forfeitures  such that expense is recorded  only  for
those share-based awards that are expected to vest. To  the extent we revise  these  estimates in  the
future, the share-based payments could  be  materially impacted in the period of revision,  as well as in
following periods. We, with the assistance  of an  independent third-party  valuation firm, determined the
fair value of the share options granted  to  employees.  The  binomial  option pricing model was applied  in
determining the estimated fair value of the options granted  to  employees.

Awards Granted to Non-employees

We  have accounted for equity instruments issued to non-employees in accordance with the

provisions of ASC 718 and ASC 505, Equity. All transactions in which goods or services are  received in
exchange for equity instruments are accounted for based on the fair value  of  the consideration received
or the fair value of the equity instrument issued, whichever is more reliably measurable. The
measurement date of the fair value of the  equity instrument issued  is the  date on which the
counterparty’s performance is completed  as there is no associated performance commitment. The
expense is recognized in the same manner  as if we  had paid cash for the services  provided by the
non-employees in accordance with ASC  505-50, Equity-based payments to non-employees.

Modification of Awards

A change in any of the terms or conditions of the  awards is accounted for as  a modification of the

award. Incremental compensation cost is measured as the  excess,  if any, of the  fair value of the
modified award over the fair value of  the original  award  immediately before its terms are  modified,
measured based on the fair value of the awards  and  other  pertinent factors  at the  modification  date.
For vested awards, we recognize incremental  compensation cost in  the period  the modification occurs.
For unvested awards, we recognize over  the remaining requisite service period, the sum of the
incremental compensation cost and the remaining unrecognized  compensation cost for the original
award on the modification date. If the  fair  value of the modified award is  lower than  the fair value of
the original award immediately before modification, the  minimum compensation cost  we recognize is
the cost of the original award.

Significant Factors, Assumptions and Methodologies Used in  Determining Fair Value

The fair value of each share option grant is  estimated  using the binomial option-pricing model.

The model requires the input of highly  subjective  assumptions  including the estimated  expected share
price volatility and, the share price upon  which (i.e. the exercise multiple) the  employees are  likely to
exercise share options. The trading history  and observation period of our own  share price  movement
has not been long enough to match the life of the  share option. Therefore, we estimate our expected
share price volatility based on the historical volatility of a  group of similar companies, which are
publicly-traded. When selecting these public  companies on which we have  based our expected  share
price volatility, we selected companies with  characteristics similar to us, including the invested capital’s
value, business model, development stage,  risk  profiles, position within  the industry, and with historical
share price information sufficient to meet  the  contractual  life of our share-based  awards. We will
continue to apply this process until a sufficient  amount  of  historical information  regarding the volatility
of our own share price becomes available. For the exercise multiple, we were not able to develop an
exercise pattern as reference, thus the exercise multiple is  based on management’s estimation, which we
believe is representative of the future  exercise pattern of the  options.  The  risk-free interest rates for
the periods within the contractual life  of  the  option are based on the U.S. Treasury yield  curve  in effect

176

during the period the options were granted. Expected dividend yield is based  on the  fact that we  have
never paid, and do not expect to pay cash  dividends in the  foreseeable future.

The assumptions adopted to estimate the fair  value of share options using the  binomial  option

pricing model were as follows:

We  are also required to estimate forfeitures  at the  time of grant, and revise those estimates  in
subsequent periods if actual forfeitures  differ from  our estimates. We  use historical data to estimate
pre-vesting option  forfeitures and record share-based compensation expense only for those awards  that
are expected to vest. To the extent that  actual  forfeitures differ from  our estimates, the difference  is
recorded  as a cumulative adjustment  in  the period the estimates  were revised.

These assumptions represented our best estimates, but  the estimates  involve inherent uncertainties

and the application of our judgment.  As a result, if factors change and we use significantly different
assumptions or estimates when valuing our share options,  our  share-based compensation expense could
be materially different.

As of December 31, 2016, there was  $63.2 million  of total unrecognized share-based compensation
expenses, net of estimated forfeitures, related to unvested share-based awards  which are  expected to  be
recognized over a weighted-average period  of  3.43 years. As of December  31, 2015, there  was
$15.63 million of total unrecognized share-based compensation expenses,  net of estimated forfeitures,
related to unvested share-based awards  which are expected to be recognized over a weighted-average
period of 2.32 years. In future periods, our share-based  compensation expense is expected  to  increase
as a result of recognizing our existing unrecognized  share-based compensation for awards that will vest
and as we issue additional share-based  awards to attract  and retain our  employees.

Fair Value Estimate

Fair value of ordinary shares

With the completion of our initial public offering in February 2016,  a  public  trading market for the
ADSs has been established, and it is  no  longer necessary for our board of directors to estimate  the fair
value of our ordinary shares in connection with  our accounting for granted share  options  and restricted
shares.

Prior to our initial public offering, we  were  required to estimate  the fair value  of  the ordinary
shares underlying our share-based awards  when performing the  fair value calculations with  the binomial
option model. Therefore, our board of  directors estimated the  fair value of our ordinary shares at
various dates, with input from management, considering the third-party  valuations  of ordinary  shares at
each  grant date. The valuations of our ordinary shares were performed  using methodologies,
approaches and assumptions consistent  with the  American Institute of Certified Public Accountants
Audit and Accounting Practice Aid Series: Valuation of Privately-Held-Company Equity  Securities  Issued
as  Compensation, or the AICPA Practice Guide. In addition, our board of directors considered various
objective and subjective factors, along with input  from  management and  the independent third-party
valuation firm, to determine the fair value  of our ordinary  shares,  including: external market conditions
affecting the biopharmaceutical industry, trends within the biopharmaceutical industry,  the prices at
which we sold preferred shares, the superior rights and preference of the preferred shares  or other
senior securities relative to our ordinary  shares at  the time of each grant, the results  of operations,
financials position, status of our research and development efforts, our stage of  development and
business strategy, and the lack of an active public market for  our ordinary  shares, and the likelihood of
achieving a liquidity event such as an initial public offering.  The option-pricing method was used  to
allocate the invested capital’s enterprise value to preferred  shares or other senior securities and
ordinary shares, taking into account the guidance  prescribed by  the AICPA  Practice Guide. This
method treats ordinary shares and preferred shares or other senior securities  as call options on the
invested  capital’s value, with exercise prices  based on their respective payoffs  upon a  liquidity event.

In determining the invested capital’s  value, we applied the discounted cash flow analysis based on

our projected cash flow using our best  estimate as of the valuation date.  The  determination  of  our
invested  capital’s value requires complex and  subjective judgments to be made regarding  our  projected
financial and operating results, our unique business risks, and our operating  history and  prospects at
the time of valuation.

Fair value of options and restricted shares

Our board of directors determined the fair  value of our  share options and the  restricted shares  as

of the date of grant, taking into consideration  the various objective and subjective factors described
above, including the conclusion of valuation of our ordinary shares  as of dates  close to the grant  dates
of our share options and the restricted shares  discussed below. We computed  the per share weighted-
average estimated  fair value for share option  grants based on the binomial option pricing model and
the per share weighted-average estimated  fair value for  restricted shares based on  per  share estimated
fair value of ordinary shares as of the  date of grant.

Derivative Instruments

ASC 815, Derivatives and Hedging, requires all contracts which meet the definition of  a derivative
to be recognized in the consolidated financial  statements  as either assets or liabilities and  recorded at
fair value. Changes in the fair value of derivative financial instruments  are either recognized
periodically in income/loss or in shareholders’ deficit  as a component of other comprehensive income
depending on the use of the derivative and whether it qualifies for  hedge  accounting. Changes in  fair
values of derivatives not qualified as  hedges  are reported in the  consolidated statements  of  operations.

178

The estimated fair values of derivative instruments are  determined at discrete  points in  time based on
the relevant market information. We calculated these estimates with reference to the  market  rates using
industry standard valuation techniques with the assistance of  an  independent third-party valuation  firm.

Fair value estimation on the exercise dates

The warrants in connection with the convertible promissory  notes and the  option to purchase
shares by rental deferral were exercised  in January and February 2016. The  fair values of the warrants
and option liabilities were determined using significant other  observable  inputs (Level 2), estimated
using the intrinsic value, which equals  to  the difference between  the share  price at  the IPO closing date
and the exercise price, as the exercise  dates  were  immediately  prior to or  very close  to  the IPO closing
date.

Fair value estimation prior to the exercise dates

As presented in the prior subsection,  ‘‘Fair Value Estimate,’’ we  applied  the discounted cash  flow

analysis to estimate the invested capital’s  value as  of various valuation dates and the option-pricing
method was used to allocate the invested capital’s value to preferred shares or other  senior securities
and ordinary shares. The derived fair  value of ordinary share  and  preferred shares was  then further
used as inputs to the Black-Scholes option pricing model to estimate the fair value of the  derivative
instruments. The Black-Scholes option pricing model requires  the input of highly  subjective
assumptions, including the risk-free interest rate, the expected volatility  of the underlying stock and the
expected life of the derivative instruments. These estimates involve inherent  risk and uncertainties and
the application of management’s judgment. To determine the expected life of the  derivative
instruments, we have considered factors  including the  timing of expected  various liquidity events  and
their respective probabilities as well as  the contractual life  of the derivative instruments.  The  risk-free
interest rates for the periods within the expected life of the  option are based on the U.S. Treasury yield
curve. We historically have been a private company  and  lack company-specific historical and  implied
volatility information. Therefore, we estimate our expected volatility based on the historical volatility of
a group of similar companies, which are publicly-traded.

We  have measured the warrants and  option liabilities  at fair values on a recurring  basis using
significant unobservable inputs (Level  3)  as of December 31, 2015. The significant unobservable inputs

179

used in the fair value measurement and the corresponding impacts to the  fair values are presented

Income Taxes

We  use the liability method of accounting for income taxes. Under this method, deferred tax  assets

and liabilities are determined based on the differences between the  financial  reporting and  the tax
bases of assets and liabilities and are measured using  enacted  tax  rates and laws that will be in effect
when the differences are expected to reverse.  A valuation allowance  is provided when it is  more likely
than not that some portion or all of  a  deferred  tax  asset will not be realized.

In November 2015, the FASB issued Accounting Standards  Update 2015-17, Balance Sheet
Classification of Deferred Taxes, which  requires deferred income tax assets and liabilities to be
classified as non-current in a classified  balance sheet, and eliminates  the prior guidance,  which required
an entity to separate deferred tax assets and liabilities into a current amount and  a non-current amount
in a classified balance sheet. We changed the manner in which we classify deferred tax  assets and
liabilities retrospectively from the fourth quarter of 2016  due to the early adoption of Accounting
Standards Update 2015-17. The adoption  of this guidance has no impact on  prior year balances as
current deferred tax assets and liabilities are both nil as  of  December 31,  2015.

We  evaluate our uncertain tax positions using  the provisions of ASC 740, Income Taxes, which
requires that realization of an uncertain  income  tax position  be  recognized in the financial statements.
The benefit to be recorded in the financial statements is the amount most  likely to be realized
assuming a review by tax authorities having all relevant information and applying current conventions.
It  is our policy to recognize interest and  penalties related  to unrecognized  tax benefits, if  any, as a
component of income tax expense.

Recent  Accounting Pronouncements

See Note 2 to our consolidated financial  statements  included in  this  Annual Report on  Form  10-K

for information regarding recent accounting pronouncements.

JOBS Act

Under Section 107(b) of the Jumpstart Our  Business Startups Act of 2012, or the  JOBS  Act, an

‘‘emerging growth company’’ can delay  the adoption  of  new or revised accounting standards  until such
time as those standards would apply to  private companies. We have irrevocably elected not to avail
ourselves  of this exemption and, as a  result, we will adopt  new  or  revised accounting standards at the
same time as other public companies  that are not emerging  growth companies.  There are other
exemptions and reduced reporting requirements  provided by the JOBS  Act that we are currently
evaluating. For example, as an emerging  growth company, we are  exempt from  Sections 14A(a) and
(b) of the Exchange Act which would otherwise require us  to  (1) submit certain executive compensation
matters to shareholder advisory votes,  such as  ‘‘say-on-pay,’’ ‘‘say-on-frequency’’ and ‘‘golden
parachutes;’’ and (2) disclose certain  executive compensation related items  such as the  correlation
between executive compensation and  performance and comparisons of our chief executive  officer’s
compensation to our median employee compensation. We also  rely on an exemption from  the rule
requiring us to provide an auditor’s attestation  report on  our internal  controls  over financial reporting
pursuant to Section 404(b) of the Sarbanes-Oxley Act and  the  rule requiring  us  to  comply with  any
requirement that may be adopted by  the PCAOB regarding mandatory audit  firm  rotation  or a
supplement to the auditor’s report providing additional information about  the audit  and the  financial
statements, known as the auditor discussion  and analysis. We will continue  to  remain an  ‘‘emerging
growth company’’ until the earliest of the  following: (1) the last day of the fiscal  year following the  fifth
anniversary of the date of the completion of our  initial public offering, (2)  the last  day of the fiscal year
in which our total annual gross revenue is  equal  to  or more than $1 billion,  (3) the  date on which we
have issued more than $1 billion in nonconvertible debt during the  previous three  years,  or (4) the  date
on which we are deemed to be a large accelerated  filer  under the  rules of the SEC.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Interest and Credit Risk

Financial instruments that are potentially subject to credit risk consist of cash and cash equivalents

and short-term investments. The carrying amounts of cash and cash  equivalents and short-term
investments represent the maximum amount of loss due  to  credit risk. We  had cash and cash
equivalents of $87.5 million, $17.9 million  and $13.9 million and  short term investments of
$280.7 million, $82.6 million and $30.5  million at  December  31, 2016, 2015  and 2014, respectively.  At
December 31, 2016, our cash and cash equivalents were deposited with various  major reputable
financial institutions located in the PRC  and  international financial  institutions outside  of the PRC. The
deposits placed with these financial institutions are  not protected by statutory  or commercial insurance.
In the event of bankruptcy of one of  these financial institutions, we may be unlikely to claim our
deposits back in full. We believe that these financial  institutions  are  of high credit quality, and  we
continually monitor the credit worthiness of these  financial institutions. At  December 31,  2016 our
short-term investments consisted primarily of U.S. Treasury securities.  We  believe that the U.S.
Treasury securities are of high credit  quality and continually monitor the credit worthiness of these
institutions.

The primary objectives of our investment activities are to preserve  principle, provide  liquidity and

maximize income without significant  increasing  risk.  Our primary exposure to market  risk relates  to
fluctuations in the interest rates which are affected by changes in the general level of PRC and U.S.
interest rates. Given the short-term nature of  our cash equivalents, we  believe that a sudden change in

181

market interest rates would not be expected  to  have a material  impact on our financial  condition
and/or results of operation. We estimate that a hypothetical 100-basis  point change in  market interest
rates would impact the fair value of our  investment portfolio as  of  December 31,  2016 by $1.6 million.

We  do not believe that our cash, cash equivalents and  short-term investments  have significant  risk
of default or illiquidity. While we believe our  cash  and cash equivalents do not contain excessive risk,
we cannot provide absolute assurance  that in the future investments  will not be subject  to  adverse
changes in market value.

Foreign Currency Exchange Rate Risk

We  are exposed to foreign exchange risk arising from  various currency  exposures. Our functional
currency is the U.S. dollar, but a portion  of our operating transactions  and  assets and liabilities are in
other currencies, such as RMB, Australian dollar  and Euro. We do not believe that we currently  have
any significant direct foreign exchange risk and  have not used any derivative financial instruments to
hedge exposure to such risk.

RMB is not freely convertible into foreign  currencies  for capital account transactions.  The value of

RMB against the U.S. dollar and other  currencies is  affected by, among other things, changes  in
China’s political and economic conditions and China’s foreign  exchange  prices. From July 21, 2005, the
RMB is permitted to fluctuate within a  narrow and managed  band against a  basket  of  certain foreign
currencies. For the RMB against U.S.  dollars, there  was  depreciation  of approximately  6.3%, 4.4% and
2.4% in the year ended December 31, 2016, 2015  and  2014.  It is  difficult to predict how market forces
or PRC or U.S. government policy may impact the  exchange rate between  the RMB and the
U.S. dollar in the future.

To the extent that we need to convert U.S. dollars  into  RMB for  capital expenditures and  working
capital and other business purpose, appreciation  of  RMB against  the U.S. dollar would  have an adverse
effect on the RMB amount we would receive from the conversion.  Conversely, if we decide  to  convert
RMB into U.S. dollars for the purpose  of making payments for  dividends  on our ordinary shares,
strategic acquisitions or investments or other business purposes,  appreciation of the  U.S. dollar  against
RMB would have a negative effect on  the U.S. dollar  amount  available  to  us.

In addition, a significant depreciation of  the RMB against the U.S. dollar may  significantly  reduce

the U.S.  dollar equivalent of our earnings or  losses.

Currency Convertibility Risk

A majority of our expenses and a significant portion  of  our  assets and  liabilities are denominated

in RMB. On January 1, 1994, the PRC government abolished the dual rate system and introduced a
single rate of exchange as quoted daily by  the  People’s Bank of  China, or PBOC. However, the
unification of exchange rates does not imply  that the RMB  may  be  readily convertible into U.S. dollars
or other  foreign currencies. All foreign exchange transactions continue to take place  either through the
PBOC or other banks authorized to  buy and sell foreign currencies  at the exchange rates quoted  by  the
PBOC. Approvals of foreign currency  payments by the PBOC  or other  institutions require submitting a
payment application form together with  suppliers’ invoices, shipping documents and signed  contracts.

Additionally, the value of the RMB is  subject to changes in  central government  policies  and
international economic and political developments affecting supply and  demand in the  PRC foreign
exchange trading system market.

Effects of Inflation

Inflation generally affects us by increasing our cost of labor and clinical  trial costs.  We do not
believe that inflation has had a material  effect on our results of operations  during  the year ended
December 31, 2016.

Item 8. Financial Statements and Supplementary Data

The financial statements required to  be  filed pursuant  to  this  item are  appended to this  Annual

Report. An index of those financial statements is in ‘‘Part IV—Item 15—Exhibits, Financial Statement

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and  Procedures

Our management, with the participation of our Chief Executive  Officer and our Chief Financial
Officer, evaluated the effectiveness of  our disclosure controls  and procedures as of December  31, 2016.
The term ‘‘disclosure controls and procedures,’’ as defined in Rule 13a-15(e) under the Exchange Act
means controls and other procedures  of a  company that are designed to ensure  that  information
required to be disclosed by the company in the reports that it files or submits under  the Exchange Act
is recorded, processed, summarized and  reported, within the time periods  specified in the  SEC’s rules
and forms. Disclosure controls and procedures include, without limitation,  controls and  procedures
designed to ensure that information required  to  be  disclosed by  a company  in the reports  that  it files  or
submits under the Exchange Act is accumulated and communicated to the company’s management,
including its principal executive and principal financial officers, as appropriate to allow timely decisions
regarding required disclosure. Management recognizes that any controls and  procedures,  no matter how
well-designed and operated, can provide only  reasonable assurance  of achieving their objectives, and
management necessarily applies its judgment in  evaluating the cost-benefit relationship of possible
controls and procedures. Based on the evaluation of  our disclosure  controls and procedures as of
December 31, 2016, our management,  including our Chief Executive Officer and  Chief Financial
Officer concluded that, as of such date,  our  disclosure controls and procedures were  effective at the
reasonable assurance level.

Management’s Annual Report on Internal  Control Over Financial  Reporting

Our management is responsible for establishing and maintaining adequate control over financial

reporting, as such term is defined in  Rules 13a-15(f) and 15d-15(f) under the Exchange  Act. Our
internal control over financial reporting is  a process designed to provide  reasonable  assurance regarding
the reliability of financial reporting and the  preparation of financial statements  for external  purposes in
accordance with accounting principles  generally  accepted in the  United States of America. Because of
its  inherent limitations, internal control  over financial reporting  may not prevent or detect
misstatements. In addition, projections of  any evaluation  of  effectiveness to future periods are  subject
to the risk that controls may become inadequate  because of changes in conditions and that the degree
of compliance with policies or procedures  may deteriorate. Management assessed the  effectiveness  of
our  internal control over financial reporting as  of December  31, 2016. In making  this  assessment,
management used  the criteria set forth in the  Internal Control—Integrated  Framework (2013) issued by
the Committee of Sponsoring Organizations  of the Treadway Commission  (COSO).

183

Based on its assessment of internal control over financial  reporting, our management, including
our  Chief Executive Officer and Chief  Financial Officer  have concluded that, as  of  December 31, 2016,
our  internal control over financial reporting was  effective. Because of its inherent limitations, internal
control over financial reporting may not prevent or detect  misstatements. Therefore, even those  systems
determined to be effective can provide  only assurance at  a reasonable level with respect  to  the financial
statement preparation and presentation.

Changes  in Internal Control over Financial Reporting

In connection with the audit of our consolidated financial statements for the years ended
December 31, 2013, 2014 and 2015, we identified  a material weakness in our internal control over
financial reporting that related to having  an insufficient  number of financial  reporting personnel  with
an appropriate level of knowledge, experience and training in application of GAAP and SEC rules and
regulations commensurate with our reporting requirements.

In 2016, we implemented measures designed to improve our internal control over  financial

reporting to remediate this material  weakness,  including the  following:

(cid:129) hiring additional financial professionals  with appropriate accounting  and SEC reporting

experience;

(cid:129) increasing the number of qualified  financial reporting  personnel;

(cid:129) improving the capabilities of existing financial reporting personnel  through training and

education in the accounting and reporting  requirements under GAAP  and SEC  rules  and
regulations;

(cid:129) developing, communicating and implementing  an accounting policy manual for our financial

reporting personnel for recurring transactions and  period-end closing processes; and

(cid:129) establishing effective monitoring and oversight controls  for non-recurring and complex

transactions to ensure the accuracy and completeness of our condensed consolidated financial
statements and related disclosures.

We  believe that the measures taken above enhanced our internal control  over financial reporting
and were sufficient to remediate the  material weakness identified. Our independent  registered  public
accounting firm will first be required  to  attest  to  the effectiveness of our internal control over financial
reporting for our Annual Report on  Form 10-K for the first  year we are no longer an EGC under  the
JOBS  Act. There is no guarantee that our  remediation efforts  will result in  the attestation from  our
independent registered public accounting  firm, if  required, that  our internal control over financial
reporting is effective as of December 31,  2017.

Except as described above, there were  no other changes in our  internal control over  financial
reporting identified in connection with the evaluation  required by  Rule 13a-15(d) and  15d-15(d) of the
Exchange Act that occurred during the three months ended December 31,  2016 that have materially
affected, or are reasonably likely to materially affect, our internal  control over financial reporting.

Attestation Report of the Registered Public  Accounting Firm

This Annual Report does not include  an  attestation report of  our registered public  accounting firm

due to an exemption established by the  JOBS  Act for ‘‘emerging growth companies.’’

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders  of BeiGene,  Ltd.

We  have audited the accompanying consolidated balance sheets of BeiGene, Ltd. (the ‘‘Company’’)

as of  December 31, 2016 and 2015, and the related consolidated  statements  of operations,
comprehensive loss, cash flows, and shareholders’ equity (deficit) for each of the  three years in the
period ended December 31, 2016. These financial statements are the responsibility of the  Company’s
management. Our responsibility is to express an  opinion on  these financial  statements  based on our
audits.

We  conducted our audits in accordance with the standards  of  the Public Company Accounting
Oversight Board (United States). Those  standards require that we  plan and perform the audit to obtain
reasonable assurance about whether  the  financial  statements are free  of material misstatement.  We
were not engaged to perform an audit  of the  Company’s internal control over  financial reporting.  Our
audits included consideration of internal  control  over financial reporting  as a basis for  designing audit
procedures that are appropriate in the circumstances, but  not  for the  purpose of expressing an opinion
on the effectiveness of the Company’s  internal control over financial reporting. Accordingly,  we express
no such opinion. An audit also includes  examining,  on a test basis,  evidence supporting  the amounts
and disclosures in  the financial statements, assessing  the accounting principles used and significant
estimates made by management, and  evaluating the  overall financial  statement presentation. We believe
that our audits provide a reasonable  basis  for our  opinion.

In our opinion, the consolidated financial statements referred to above present fairly,  in all

material respects, the consolidated financial  position of  BeiGene, Ltd. at  December 31, 2016  and 2015,
and the consolidated results of its operations and its cash  flows for  each  of  the three years in  the
period ended December 31, 2016, in  conformity with U.S. generally  accepted accounting  principles.

1. Organization

BeiGene, Ltd. (the ‘‘Company’’) is a globally focused, clinical-stage  biopharmaceutical company

with the goal of becoming a leader in the discovery and development of  innovative, molecularly
targeted and immuno-oncology drugs for the treatment of cancer.  The  Company’s development  strategy
is based on a novel translational platform that  combines its  unique access to internal patient-derived
biopsies with strong oncology biology. The Company  was incorporated under the laws of the  Cayman
Islands as an exempted company with limited liability on October  28, 2010.

Initial public offering

On February 8, 2016, the Company completed its initial public offering (‘‘IPO’’) on the NASDAQ
Global Select Market. 6,600,000 ADSs  representing 85,800,000 ordinary  shares were sold at $24.00 per
ADS, or $1.85 per share (the  ‘‘IPO Price’’).  Additionally,  the underwriters exercised  their  options to
purchase an additional 990,000 ADSs representing 12,870,000  ordinary shares from the  Company. Net
proceeds from the IPO including underwriter  options after deducting underwriting discount and
offering expenses were $166,197. The  deferred  IPO costs of $15,963 were recorded as a  reduction of
the proceeds received from the IPO in shareholders’ equity.

Follow-on public offering

On November 23, 2016, the Company completed  a follow-on public offering  at a  price of $32.00

per ADS, or $2.46 per share. In this offering, the Company sold 5,781,250 ADSs representing
75,156,250 ordinary shares. Additionally,  the underwriters  exercised their  options to purchase an
additional 850,000 ADSs representing 11,050,000 ordinary  shares  from the Company. The selling
shareholders sold 468,750 ADSs representing 6,093,750 ordinary shares. Net proceeds  from this offering
including underwriter options after deducting the underwriting discount  and offering expenses were
$198,625. The Company did not receive any proceeds  from the sale of the  shares by the selling
shareholders. The deferred follow-on public offering  costs  of $13,575 were recorded  as a reduction of
the proceeds received from the offering in  shareholders’ equity.

2. Summary of significant accounting  policies

Basis of presentation and principles  of  consolidation

The consolidated financial statements  of the Company  have been  prepared  in accordance with  U.S.

generally accepted accounting principles  (‘‘GAAP’’). The consolidated financial statements include the
financial statements of the Company  and  its wholly-owned  subsidiaries. All significant intercompany
transactions and balances between the Company and its wholly-owned  subsidiaries are eliminated  upon
consolidation.

Use of estimates

The preparation of the consolidated  financial statements in conformity with GAAP  requires
management to make estimates and  assumptions that affect the reported  amounts  of assets and
liabilities, and disclosures of contingent assets and liabilities at the  date of the  financial  statements  and
the reported amounts of revenues and expenses  during the period. Areas where management  uses
subjective judgment include, but are not limited to, estimating the useful lives of long-lived assets,
identifying separate accounting units and estimating the best estimate of  selling price of  each
deliverable in the Company’s revenue arrangements, assessing the  impairment of long-lived  assets,

except for number of shares and per share data)

2. Summary of significant accounting  policies  (Continued)

share-based compensation expenses,  realizability of deferred tax assets and the  fair value  of financial
instruments. Management bases the estimates on historical  experience and various other assumptions
that are believed to be reasonable, the results  of  which form the basis for making judgments about  the
carrying values of  assets and liabilities. Actual  results could differ from these estimates.

Functional Currency and Foreign Currency  Translation

Functional Currency

The determination of the respective functional  currency is based on  the criteria  of Accounting
Standard Codification (‘‘ASC’’) 830, Foreign Currency Matters. The functional currency of the Company,
BeiGene AUS Pty Ltd., BeiGene (Hong Kong) Co.,  Limited, BeiGene 101 Ltd and BeiGene (USA) is
the United States dollar (‘‘$’’ or ‘‘U.S. dollar’’).  The Company’s PRC  subsidiaries determined their
functional currencies to be RMB. The Company  uses the  U.S.  dollar as  its  reporting currency.

Foreign Currency Translation

For subsidiaries whose functional currencies  are not the  U.S. dollar, the Company uses  the average

exchange rate for the year and the exchange rate  at the  balance sheet date, to translate the operating
results and financial position to U.S.  dollar,  the reporting currency, respectively. Translation differences
are recorded in accumulated other comprehensive income/(loss), a component of shareholders’ equity/
deficit. Transactions denominated in currencies other  than the functional currency  are translated into
the functional currency at the exchange rates  prevailing on the transaction  dates. Foreign  currency
denominated financial assets and liabilities  are remeasured at the exchange rates prevailing at the
balance sheet date. Exchange gains and  losses are included in the  consolidated  statements of
comprehensive loss.

Cash and cash equivalents

Cash and cash equivalents consist of  cash on hand and bank deposits, which  are unrestricted as to
withdrawal and use. The Company considers all highly liquid investments with  an original maturity date
of three months or less at the date of  purchase  to  be  cash equivalents. Cash  equivalents which consist
primarily of money market funds are stated at  fair value.

Short-term investments

Short-term debt investments held to  maturity  are carried at  amortized cost  when the Company has
the ability and positive intent to hold these  securities until maturity. When the Company does  not  have
the ability or positive intent to hold short-term debt  investments until maturity, these securities  are
classified as available-for-sale. None of the  Company’s fixed  maturity securities met the criteria for
held-to-maturity classification at December 31, 2016  and  2015.

Available-for-sale securities are stated at  fair value, with  the unrealized  gains and losses, net  of  tax,

reported in other comprehensive income/loss. The net carrying value of debt securities classified as

(Amounts in thousands of U.S. Dollar (‘‘$’’)  and Renminbi (‘‘RMB’’),
except for number of shares and per share data)

2. Summary of significant accounting  policies  (Continued)

available-for-sale is adjusted for amortization  of premiums and accretion  of discounts  to  maturity. Such
amortization is computed using the effective interest method  and included in interest income. Interest
and  dividends are included in interest  income.

When the fair value of a debt security classified as  available-for-sale is less  than its amortized  cost,

the Company assesses whether or not: (i) it has the intent to sell the security or  (ii) it is more  likely
than  not that the Company will be required to sell  the security before its anticipated recovery. If either
of these conditions is met, the Company  must recognize  an  other-than-temporary impairment  through
earnings for the difference between the debt security’s amortized cost  basis and its fair value. No
impairment losses were recorded for any periods presented.

The cost of securities sold is based on  the specific identification method.

Property and Equipment

Property and equipment are stated at  cost, less  accumulated  depreciation and  amortization.

Depreciation is computed using the straight-line method  over  the estimated useful lives of the
respective assets as follows:

Office Equipment . . . . . . . . . . . . . . . . . . . . . . .
Electronic Equipment . . . . . . . . . . . . . . . . . . . .

Useful Life

Impairment of long-lived assets

Long-lived assets are reviewed for impairment in  accordance with  authoritative  guidance for
impairment or disposal of long-lived  assets. Long-lived assets are reviewed for events or  changes in
circumstances, which indicate that their  carrying value may not be recoverable. Long-lived  assets are
reported at the lower of carrying amount  or  fair value less cost to sell. For the years ended
December 31, 2016, 2015 and 2014, there was no impairment of  the  value  of  the Company’s  long-lived
assets.

Fair  value measurements

Fair value of financial instruments

Financial instruments of the Company  primarily include cash  and cash equivalents, short-term
investments, long-term bank loan, accounts payable,  senior promissory note, convertible preferred
shares, and warrants and option liabilities. As of December 31, 2016  and 2015, the carrying  values of
cash and cash equivalents and accounts payable approximated  their  fair values due to the short-term
maturity of these instruments. The short-term investments  represented  the available-for-sale debt

2. Summary of significant accounting  policies  (Continued)

securities which are recorded at fair  value based  on  quoted prices in active markets with  unrealized
gain or loss recorded in other comprehensive  income or loss.  The  long-term bank loan approximates its
fair value due to the fact that the related interest rate  approximates the  rate currently offered by
financial institutions for similar debt instrument of comparable maturities. The  warrants and option
liabilities were recorded at fair value as determined on the respective  issuance  dates and subsequently
adjusted to the fair value at each reporting  date. The senior  promissory  note and convertible preferred
shares were initially recorded at issue price  net of  issuance costs. Prior to the  exercise  dates, the
Company determined the fair values of the warrants  and option liabilities with  the assistance  of  an
independent third party valuation firm.  On the  exercise dates, the Company  determined the fair  values
of the warrants and option liabilities using  the intrinsic value, which equals  to  the difference between
the share price at the IPO closing date and the  exercise price,  as the exercise dates were immediately
prior to or very close to the IPO closing date.

The Company applies ASC topic 820 (‘‘ASC  820’’), Fair Value Measurements and Disclosures, in
measuring fair value. ASC 820 defines fair  value,  establishes a framework for measuring  fair value  and
requires disclosures to be provided on fair value  measurement.  ASC  820 establishes a three-tier fair
value hierarchy, which prioritizes the  inputs  used  in measuring fair value  as follows:

Level 1—Observable inputs that reflect quoted prices (unadjusted) for identical assets  or liabilities

in active markets.

Level 2—Include other inputs that are directly or indirectly  observable  in the  marketplace.

Level 3—Unobservable inputs which  are supported  by little or no market activity.

ASC 820 describes three main approaches to measuring the fair value of  assets and liabilities:

(1) market approach; (2) income approach and  (3)  cost approach. The market approach uses prices
and other relevant information generated  from  market  transactions involving identical or comparable
assets or liabilities. The income approach  uses valuation techniques to convert future amounts to a
single present value amount. The measurement is based on the  value  indicated by current  market
expectations about those future amounts. The cost approach is based on  the amount that would
currently be required to replace an asset.

Warrants and option fair value estimation on  the exercise dates

The warrants in connection with the convertible promissory  notes and the  option to purchase
shares by rental deferral were exercised  in January and February 2016. The  Company determined  the
exercise date fair value of the warrants  and  option using  significant other observable inputs (Level 2).
The fair values of the warrants and option liabilities were estimated using the intrinsic value, which
equals to the difference between the share price at the IPO  closing date and the exercise  price, as the
exercise dates were immediately prior  to  or very close to the  IPO closing date.

Warrants and option fair value estimation prior to the  exercise dates

Prior to the exercise dates, the Company measured the warrants  in connection with the convertible

Realized and unrealized gain or loss for the years ended December  31, 2016, 2015 and 2014  was

recorded as ‘‘Changes in fair value of financial instruments’’  in the consolidated statements of
operations.

Revenue recognition

The Company recognizes revenues from research and development collaborative arrangements

when persuasive evidence of an arrangement exists, delivery has  occurred or services have  been
rendered, the fee is fixed or determinable, and there is reasonable assurance that the related amounts
are collectible in accordance with ASC 605, Revenue Recognition (‘‘ASC 605’’). The Company’s
collaborative arrangements may contain multiple elements, including grants of licenses to intellectual
property rights, agreement to provide  research and development services and other deliverables.  The
deliverables under such arrangements  are  evaluated under ASC 605-25, Multiple-Element Arrangements.
Pursuant to ASC 605-25, each required deliverable  is evaluated to determine whether it qualifies as a
separate unit of accounting based on  whether  the deliverable has ‘‘stand-alone value’’ to the customer.
The collaborative arrangements do not include a right of return for any deliverable. The arrangement’s
consideration that is fixed or determinable,  excluding contingent payments, is then  allocated  to  each
separate unit of accounting based on  the relative selling price  of  each deliverable. The relative selling
price for each deliverable is determined using vendor specific objective evidence (‘‘VSOE’’)  of  selling
price or third party evidence (‘‘TPE’’)  of  selling price if  VSOE does not  exist. If  neither VSOE nor
TPE exists, the Company uses the best  estimate of the  selling price (‘‘BESP’’)  for the  deliverable. In
general, the consideration allocated to each unit  of  accounting is recognized as  the related  goods or
services are delivered, limited to the consideration  that  is not contingent upon future deliverables.
Non-refundable payments received before all of the relevant criteria for revenue  recognition are
satisfied are recorded as advances from  customers.

Upfront non-refundable payments for licensing  the Company’s intellectual property are  evaluated
to determine if the licensee can obtain stand-alone value from the license separate from the  value of
the research and development services  and other deliverables  in the arrangement to be provided  by  the
Company. The Company acts as the principal  under its arrangements and licensing  intellectual property
is part of its ongoing major or central operations. The license  right is not contingent upon the delivery
of additional items or meeting other specified performance conditions.  Therefore,  when stand-alone
value of the license is determinable, the  allocated consideration is recognized  as collaboration revenue
upon delivery of the license rights.

As the Company acts as the principal  under  its arrangements, and research and  development

services are also part of its ongoing major or central operations, it recognizes the allocated
consideration related to reimbursements  of research and development costs as collaboration  revenue
when delivery or performance of such  services  occurs.

Product development, royalties and commercial event payments (collectively,  ‘‘target  payments’’)

under collaborative arrangements are  triggered  either by the results of the Company’s research and
development efforts, achievement of regulatory goals or  by specified  sales  results by a  third party

collaborator. Under ASC 605-28, Milestone Method of Revenue Recognition, an accounting policy
election can be made to recognize a payment that is contingent upon the achievement  of a substantive
milestone in its entirety in the period in  which  the milestone is achieved. The Company  elected  not  to
adopt the milestone method of revenue  recognition under ASC 605-28.

Targets  related to the Company’s development-based activities may include initiation of various

phases of clinical trials and applications and acceptance  for product approvals by regulatory  agencies.
Due to the uncertainty involved in meeting these development-based targets, the Company  would
account for development-based targets  as collaboration revenue  upon achievement of the respective
development target. Royalties based  on  reported sales  of licensed  products will be recognized as
collaboration revenue based on contract  terms  when reported sales are reliably measurable and
collectability is reasonably assured. Targets related  to  commercial activities may be triggered  upon
events such as first commercial sale of  a  product  or when  sales  first achieve a defined level. Since  these
targets would be achieved after the completion of the  Company’s  development activities, the  Company
would account for  the commercial event  targets in the  same  manner  as royalties, with collaboration
revenue recognized upon achievement  of  the target.  To date, none of the products have been approved.
Hence, no revenue has been recognized  related to royalties or commercial event  based targets in any of
the periods presented. Any subsequent payments to be made to the collaborator such  as profit  sharing
payments based on net sales that are  not  related to research and development services would  be
recorded  as expenses from the collaborative arrangement.  To date, no payments have been made  to  the
collaborator.

Research and development expenses

Research and development expenses represent costs  associated  with the collaborative
arrangements, which primarily include  (i)  payroll and related costs (including share-based
compensation) associated with research and  development personnel, (ii) costs  related to clinical trials
and preclinical testing of the Company’s  technologies under development, (iii)  costs to develop the
product  candidates, including raw materials and supplies, product testing, depreciation,  and facility
related expenses, (iv) expenses for research services  provided by  universities  and contract laboratories,
including sponsored research funding,  and (v) other  research and development expenses. Research and
development expenses are charged to expense as  incurred when  these expenditures relate to the
Company’s research and development  services and have no alternative future uses.

Clinical trial costs are a significant component of the Company’s research and development

expenses. The Company has a history of  contracting with third parties  that  perform  various clinical  trial
activities on behalf of the Company in  the ongoing development of the Company’s product  candidates.
Expenses related to clinical trials are accrued  based on the  Company’s estimates of the actual  services
performed by the third parties for the  respective period. If the contracted amounts are modified (for
instance, as a result of changes in the  clinical trial protocol or scope of work to be performed), the
Company will modify the related accruals accordingly on  a  prospective basis.  Revisions in the  scope  of
a contract are charged to expense in  the  period in which the  facts  that give rise  to  the revision become
reasonably certain. There were no material  adjustments  for a change  in estimate  to  research  and
development expenses in the accompanying consolidated financial statements for the years ended
December 31, 2016, 2015 and 2014.

Government grants

Government financial incentives that involve no  conditions  or  continuing  performance obligations

of the Company are recognized as other  non-operating  income upon receipt.

Leases are classified at the inception  date as  either a capital lease or an  operating lease. The
Company assesses a lease to be a capital lease  if any of the following conditions  exist: a) ownership is
transferred to the lessee by the end of  the lease term, b) there is  a  bargain purchase option,  c) the
lease term is at least 75% of the property’s estimated remaining  economic life or  d) the present value
of the minimum lease payments at the beginning of  the lease term is  90% or more  of the fair value of
the leased property to the lessor at the inception date. A capital  lease is  accounted for  as if there was
an acquisition of an asset and an incurrence  of an  obligation at the inception of the  lease. The
Company has no capital leases for the years presented.

All other leases are accounted for as operating leases wherein rental payments  are expensed on a

straight-line basis over the periods of their respective lease  terms. The Company leases office space,
employee accommodation and manufactory  space under operating lease agreements. Certain of the
lease agreements contain rent holidays.  Rent  holidays are considered  in determining the  straight-line
rent expense to be recorded over the lease term.  The lease term begins on the date of initial  possession
of the lease property for purposes of recognizing lease  expense on straight-line basis over the  term of
the lease.

Comprehensive loss

Comprehensive loss is defined as the  changes  in equity  of the  Company during a period from
transactions and other events and circumstances excluding transactions  resulting from investments  by
owners and distributions to owners. Among other disclosures, ASC 220, Comprehensive Income,
requires that all items that are required to be recognized under  current accounting standards as
components of comprehensive loss be  reported in  a financial statement  that  is displayed with the  same
prominence as other financial statements.  For each of the periods presented, the Company’s
comprehensive loss includes net loss, foreign currency translation  adjustments and  unrealized holding
losses associated with the available-for-sale securities, and is presented in  the consolidated statements
of comprehensive loss.

Stock-based compensation

Awards granted to employees

The Company applies ASC 718, Compensation—Stock Compensation (‘‘ASC 718’’), to account for

its  employee share-based payments. In  accordance with  ASC 718,  the  Company determines whether an
award should be classified and accounted for  as a liability award  or  equity award. All the  Company’s
grants of share-based awards to employees were classified as  equity awards and are recognized in  the

except for number of shares and per share data)

2. Summary of significant accounting  policies  (Continued)

financial statements based on their grant  date fair values. Specifically, the grant date  fair value of share
options are calculated using an option  pricing model. The Company has elected to recognize
compensation expense using the straight-line  method for  all employee  equity  awards granted with
graded vesting based on service conditions provided that  the amount of compensation  cost recognized
at any date is at least equal to the portion of the grant-date value  of  the options that are vested at that
date. The Company uses the accelerated method  for all awards granted with graded vesting based on
performance conditions. To the extent  the required  vesting  conditions are not met resulting in the
forfeiture of the share-based awards,  previously  recognized compensation expense relating  to  those
awards are reversed. ASC 718 requires  forfeitures  to  be  estimated  at  the  time of  grant and  revised,  if
necessary, in the subsequent period if  actual  forfeitures differ from initial estimates.

Forfeiture rates are estimated based  on historical and  future expectations of employee turnover

rates and are adjusted to reflect future changes in  circumstances  and facts, if any.  Share-based
compensation expense is recorded net of  estimated  forfeitures  such that expense is recorded  only  for
those share-based awards that are expected to vest. To the extent the  Company revises these  estimates
in the  future, the share-based payments could  be  materially impacted in the period of revision, as well
as in following periods. The Company, with the assistance of an independent third party  valuation firm,
determined the fair value of the stock options  granted to employees. The binomial option  pricing
model was applied in determining the estimated fair value of the  options granted to employees.

Awards granted to non-employees

The Company has accounted for equity  instruments issued  to  non-employees in  accordance  with

the provisions of ASC 718 and ASC  505, Equity. All transactions in which goods or services are
received in exchange for equity instruments are accounted for based  on the  fair value  of the
consideration received or the fair value of the equity instrument issued, whichever is more  reliably
measurable. The measurement date of  the fair value of the equity instrument issued is  the date  on
which  the counterparty’s performance is  completed as there is  no associated  performance commitment.
The expense is recognized in the same  manner as  if the  Company had paid  cash for the services
provided by the non-employees in accordance with ASC 505-50, Equity-based payments to
non-employees.

Modification of awards

A change in any of the terms or conditions of the awards is accounted for as  a modification of the

award. Incremental compensation cost is measured as  the excess,  if any, of the  fair value of the
modified award over the fair value of  the original award immediately before its terms are  modified,
measured based on the fair value of the awards and other pertinent factors  at the  modification  date.
For vested awards, the Company recognizes incremental compensation cost in the period the
modification occurs. For unvested awards, the  Company recognizes  over the  remaining requisite  service
period, the sum of the incremental compensation cost  and the remaining unrecognized  compensation
cost for the original award on the modification date.  If the fair value  of  the modified award is lower

than  the fair value of the original award  immediately  before modification, the minimum compensation
cost the Company recognizes is the cost  of  the original award.

Derivative instruments

ASC 815, Derivatives and Hedging, requires all contracts which meet the definition of  a derivative
to be recognized in the consolidated financial  statements  as either assets or liabilities and  recorded at
fair value. Changes in the fair value of derivative financial instruments  are either recognized
periodically in income/loss or in shareholders’ deficit  as a component of other comprehensive income
depending on the use of the derivative and whether it qualifies for  hedge  accounting. Changes in  fair
values of derivatives not qualified as  hedges  are reported in the  consolidated statements  of  operations.
The estimated fair values of derivative instruments  are determined at discrete  points in  time based on
the relevant market information. These estimates are calculated with  reference to the  market rates
using industry standard valuation techniques with the assistance of an independent  third party  valuation
firm.

Income taxes

The Company uses the liability method of accounting  for income  taxes. Under this method,
deferred tax assets and liabilities are  determined  based on  the differences between the financial
reporting and the tax bases of assets  and liabilities and  are measured using enacted tax  rates  and laws
that will be in effect when the differences  are  expected to  reverse. A valuation allowance is provided
when it is more likely than not that some portion or all of a deferred tax asset will not be realized.

In November 2015, the FASB issued Accounting Standards  Update 2015-17, Balance Sheet

Classification of Deferred Taxes, which requires deferred income tax  assets and liabilities to be classified
as non-current in a classified balance sheet, and  eliminates the  prior guidance, which  required an  entity
to separate deferred tax assets and liabilities  into  a current amount and a non-current amount in a
classified balance sheet. The Company  changed  the manner in  which it classifies deferred  tax assets and
liabilities retrospectively from the fourth quarter of 2016  due to the early adoption of Accounting
Standards Update 2015-17. The adoption  of this guidance has no impact on  prior year balances as
current deferred tax assets and liabilities are both nil as  of  December 31,  2015.

The Company evaluates its uncertain  tax positions using the  provisions  of  ASC  740, Income Taxes,

which  requires that realization of an  uncertain  income  tax position be recognized in the  financial
statements. The benefit to be recorded  in the financial statements  is the amount most  likely to be
realized assuming a review by tax authorities  having  all relevant information and applying  current
conventions. It is the Company’s policy to recognize interest and  penalties related  to  unrecognized tax
benefits, if any, as a component of income tax  expense.

Loss per share

Loss per share is calculated in accordance with ASC  260, Earnings per Share. Basic loss per
ordinary share is computed by dividing  net loss attributable  to  ordinary shareholders  by  the weighted

except for number of shares and per share data)

2. Summary of significant accounting  policies  (Continued)

average number of ordinary shares outstanding during  the period using the two-class method. Under
the two-class method, net income is allocated  between  ordinary shares and participating securities
based on  dividends declared (or accumulated)  and  participating rights in undistributed  earnings as  if  all
the earnings for the reporting period had been distributed. The Company’s convertible preferred  shares
and  restricted stock are participating securities because they have  contractual  rights to share  in the
profits of the Company.

However, both the convertible preferred shares and restricted stock  do not have contractual rights

and  obligations to share in the losses of  the Company. For the periods presented herein, the
computation of basic loss per share using the two-class  method is  not  applicable as the Company  is in a
net loss position.

Diluted loss per share is calculated by dividing  net loss attributable  to  ordinary shareholders  as
adjusted for the effect of dilutive ordinary equivalent shares, if any, by  the weighted average number of
ordinary and dilutive ordinary equivalent shares outstanding during the period. Ordinary equivalent
shares consist of the ordinary shares issuable  upon  the conversion  of the Company’s  convertible
preferred shares using the if-converted method, and  ordinary  shares issuable  upon the  conversion  of
the share options and unvested restricted  stock, using  the treasury stock method.  Ordinary share
equivalents are excluded from the computation  of diluted  loss per share if their effects would  be
anti-dilutive. Basic and diluted loss per ordinary  share is  presented  in the  Company’s consolidated
statements of operations.

Segment information

In accordance with ASC 280, Segment Reporting, the Company’s chief operating decision maker,
the Chief Executive Officer, reviews the  consolidated  results when making decisions about  allocating
resources and assessing performance  of the Company as a  whole and hence, the Company has  only  one
reportable segment. The Company does not distinguish between markets or segments for the purpose
of internal reporting. As the Company’s  long-lived assets and revenue are substantially located  in and
derived from the PRC, no geographical  segments are presented.

Concentration of risks

Concentration of credit risk

Financial instruments that are potentially subject  to  credit risk consist of cash and cash equivalents

and short-term investments. The carrying amounts of cash and cash equivalents and short-term
investments represent the maximum amount of loss due to credit risk. As  of December 31, 2016 and
2015, $87,514 and $17,869 were deposited  with various major reputable  financial institutions located in
the PRC and international financial institutions outside of the PRC. The deposits  placed  with financial
institutions are not protected by statutory  or commercial insurance. In  the event of bankruptcy of one
of these  financial institutions, the Company may be unlikely  to  claim  its deposits back in full.
Management believes that these financial  institutions are of high credit  quality and continually monitors

the credit worthiness of these financial institutions. As of  December 31,  2016 and 2015, the Company
had  debt security investments amounting  to  $280,660 and $82,617, respectively.

At December 31, 2016, the Company’s debt security investments comprised primarily of U.S.
treasury securities. The Company believes that  U.S.  treasury  securities are of  high credit  quality and
continually monitors the credit worthiness of these institutions.

Customer concentration risk

For the years ended December 31, 2016, 2015 and 2014, substantially all of  the Company’s revenue

has been generated solely from one customer,  Merck  KGaA,  Darmstadt Germany.

Business, customer, political, social and economic  risks

The Company participates in a dynamic  high technology industry and believes  that  changes in any
of the following areas could have a material adverse effect on the  Company’s future  financial  position,
results of operations or cash flows: changes in  the overall  demand for services and products;
competitive pressures due to new entrants; advances and new trends  in new  technologies and industry
standards; changes in clinical research organizations; changes  in certain strategic  relationships or
customer relationships; regulatory considerations; copyright regulations; and risks  associated with  the
Company’s ability to attract and retain employees  necessary to support  its  growth. The Company’s
operations could be also adversely affected by significant political, economic  and social uncertainties in
the PRC.

Currency convertibility risk

A majority of the Company’s expenses  and  a significant portion of the Company’s  assets and
liabilities are denominated in RMB. On January 1, 1994,  the PRC government abolished  the dual rate
system and introduced a single rate of  exchange as quoted daily  by the People’s Bank  of  China (the
‘‘PBOC’’). However, the unification of the exchange rates does  not imply  that  the RMB may be readily
convertible into U.S. dollar or other foreign currencies.  All foreign exchange transactions continue to
take place either through the PBOC or other banks authorized to buy and  sell foreign  currencies  at the
exchange rates quoted by the PBOC. Approvals of  foreign currency payments  by  the PBOC or  other
institutions require submitting a payment application form together with suppliers’ invoices, shipping
documents and signed contracts.

Additionally, the value of the RMB is subject to changes in  central government  policies  and
international economic and political developments affecting supply and  demand in the  PRC foreign
exchange trading system market.

Foreign currency exchange rate risk

From July 21, 2005, the RMB is permitted to fluctuate  within a  narrow and managed  band against

a basket of certain foreign currencies. For  RMB against U.S. dollar, there was depreciation of

approximately 6.3%, 4.4% and 2.4%  in the year ended December  31, 2016,  2015 and  2014. It is difficult
to predict how market forces or PRC or U.S. government policy may impact the exchange rate  between
the RMB and the U.S. dollar in the future.

To the extent that the Company needs to convert U.S. dollar  into  RMB for capital expenditures

and  working capital and other business purposes, appreciation of RMB  against U.S. dollar would have
an adverse effect on the RMB amount  the Company would receive from  the conversion. Conversely, if
the Company decides to convert RMB  into  U.S. dollar for  the purpose of making payments  for
dividends on ordinary shares, strategic acquisitions or  investments or other business purposes,
appreciation of U.S. dollar against RMB would  have a negative  effect on  the U.S.  dollar amount
available to the Company. In addition, a significant depreciation of the RMB against the  U.S. dollar
may significantly reduce the U.S. dollar equivalent of the Company’s  earnings or losses.

Reclassifications

Certain prior year amounts have been reclassified  to  conform to the current  year presentation.

Recent accounting  pronouncements

In August 2015, the FASB issued Accounting Standards Update  (‘‘ASU’’) No. 2015-14, Revenue
from Contracts with Customers-Deferral  of  the  effective date (‘‘ASU 2015-14’’). The amendments  in ASU
2015-14  defer the effective date of ASU No. 2014-09, Revenue from Contracts with Customers, (‘‘ASU
2014-09’’), issued in May 2014. According  to  the amendments in ASU 2015-14, the  new revenue
guidance ASU 2014-09 is effective for annual reporting periods beginning after December 15,  2017,
including interim reporting periods within that reporting period. Earlier application  is permitted only as
of annual reporting periods beginning  after December 15, 2016,  including interim reporting periods
within that reporting period. In March  2016,  the FASB issued ASU  No. 2016-08, Revenue from
Contracts with Customers—Principal versus Agent Considerations (‘‘ASU 2016-08’’), which clarifies the
implementation guidance on principal versus agent considerations. In  April 2016,  the FASB  issued ASU
No. 2016-10, Revenue from Contracts with Customers—Identifying Performance Obligations and Licensing
(‘‘ASU 2016-10’’), which clarify guidance related to identifying performance obligations and licensing
implementation guidance contained in  ASU No.  2014-09. In May 2016,  the  FASB issued ASU
No. 2016-12, Revenue from Contracts with Customers—Narrow-Scope Improvements and Practical
Expedients (‘‘ASU 2016-12’’), which addresses narrow-scope  improvements to the guidance on
collectability, non-cash consideration,  and  completed contracts at transition and provides  practical
expedients for contract modifications at  transition and an accounting policy election related to the
presentation of sales taxes and other similar  taxes collected from customers. The effective  date for the
amendment in ASU 2016-08, ASU 2016-10 and ASU  2016-12 are the same as the effective date of
ASU No. 2014-09.  The Company will  adopt the  new standard under the modified retrospective
approach, effective January 1, 2018, and  is in  the process  of evaluating its collaboration agreements
with Merck KGaA, Darmstadt Germany to determine the  impact the adoption of these ASUs has on
its  consolidated financial statements,  if any.

2. Summary of significant accounting  policies  (Continued)

In February 2016, the FASB issued ASU  No. 2016-02, Leases, which requires lessees to recognize

assets and liabilities related to lease  arrangements longer than 12 months on  the balance sheet.  This
standard also requires additional disclosures by lessees and  contains  targeted changes to accounting  by
lessors. The updated guidance is effective for interim  and  annual periods beginning  after December  15,
2018, and early adoption is permitted. The recognition, measurement, and  presentation of expenses and
cash flows arising from a lease by a lessee have not significantly  changed  from previous GAAP. The
Company is currently evaluating the  impact on its  financial  statements  of  adopting this guidance.

In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based

Payment Accounting (‘‘ASU  2016-09’’). The amendments  in ASU 2016-09 simplify several aspects of the
accounting for employee share-based  payment transactions, including the  income  tax consequences,
classification of awards as either equity or liabilities, and  classification  on the  statement  of  cash flows.
For public business entities, ASU 2016-09 is effective  for annual  periods beginning after December 15,
2016 and interim periods within those annual  periods. The Company  does not expect the
implementation of this standard to materially impact  its future  stock-based  compensation  expense.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (‘‘ASU
2016-13’’). The amendments in ASU  2016-13 update guidance on reporting credit losses  for assets held
at amortized cost basis and available-for-sale debt securities. These amendments  affect loans,  debt
securities, trade receivables, net investments in  leases, off balance sheet credit exposures,  reinsurance
receivables, and any other financial assets  not excluded from  the scope that have the  contractual  right
to receive cash. For public business entities that are U.S. SEC filers, ASU 2016-13 is  effective for  fiscal
years beginning after December 15, 2019, and interim periods  within those fiscal years. The Company is
currently evaluating the method of adoption to be utilized and it cannot currently estimate the financial
statement impact of adoption.

In August 2016, the FASB issued ASU No.  2016-15, Statement of cash flows—Classification of
Certain Cash Receipts (‘‘ASU  2016-15’’). The amendments  in ASU 2016-15 addresses  eight  specific cash
flow issues, including debt prepayment or  debt  extinguishment  costs, settlement of  zero-coupon  debt
instruments or other debt instruments  with coupon  interest rates that are  insignificant in  relation to the
effective interest rate of the borrowing, contingent consideration payments  made after  a business
combination, proceeds from the settlement of insurance claims; proceeds  from the settlement  of
corporate-owned life insurance policies  (COLIs) (including bank-owned life  insurance policies
(BOLIs)), distributions received from  equity method investees,  beneficial interests in  securitization
transactions and separately identifiable cash flows and application of  the  predominance  principle. For
public business entities that are U.S. SEC  filers,  ASU  2016-15 is effective for  fiscal years beginning
after December 15, 2017, and interim  periods within  those fiscal years. The Company is currently
evaluating the method of adoption to be utilized and it  cannot  currently estimate the financial
statement impact of adoption.

In October 2016, the FASB issued ASU  No. 2016-16, Income taxes—Intra-entity transfers of assets

other than inventory (‘‘ASU  2016-16’’). The amendments in ASU  2016-16 require that entities recognize
the income tax consequences of an intra-entity transfer of an  asset other than inventory when  the

intra-entity asset transfer under Topic 810, Consolidation,  or for  an intra-entity transfer of inventory.
For public business entities that are U.S. SEC filers, ASU 2016-16 is  effective for  fiscal years beginning

During  2016, there is an increase in the valuation allowance by  $1,627 which included the effect of
expired net operating losses of $1,466. Valuation allowances  have been provided on deferred tax assets
where,  based on all available evidence, it  was  considered more likely than not that some portion or  all
of the recorded deferred tax assets will  not  be  realized in  future periods. The Company recorded a full
valuation allowance against deferred  tax  assets related  to  net operating losses, and  recorded a valuation
allowance against the portion of the deferred tax assets related to deductible  temporary differences.

As of December 31, 2016, the Company had net operating losses of approximately  $27,948 derived

from entities in the PRC, which can  be  carried forward to offset future net profit  for income tax
purposes. The net operating loss in PRC entities will expire, if unused,  beginning  January 1, 2018
through 2022.

No unrecognized tax benefits and related  interest and penalties were recorded  in any of the
periods presented. The Company’s management  does  not  expect the amount of unrecognized tax
benefits would increase significantly in the next 12 months. In general, the PRC tax authorities have up
to five years to conduct examinations of the Company’s  tax  filings. Accordingly, the PRC subsidiaries’
tax years 2012 through 2016 remain open  to examination by the respective taxing authorities.

Option to purchase shares by rental deferral

On September 1, 2012, in conjunction with a lease  agreement of one of  its premises,  the Company
granted the landlord an option to purchase the Company’s ordinary shares (the ‘‘Option’’) in exchange
for the deferral of the payment of one  year’s  rental  expense. The Option  was a freestanding instrument
and was recorded as a liability in accordance with ASC480, Distinguishing Liabilities from Equity. The
Option was initially recognized at fair  value with  subsequent changes in  fair value recorded in  losses.
Prior to the Company’s IPO, the Company determined the fair value  of the Option with the  assistance
of an independent third party valuation firm. On February 8,  2016, immediately prior  to  the Company’s
IPO, the landlord exercised the Option to purchase 1,451,586 ordinary shares  of  the Company. As the
exercise date was the IPO closing date, the exercise  date fair value of the Option  of  $2,540 was
determined based on its intrinsic value, which equaled the  difference between the  share price at the
IPO closing date and the exercise price of such purchased ordinary  shares. During the years ended

8. Warrants and option liabilities (Continued)

December 31, 2016, 2015 and 2014, the Company recognized a loss from  the  increase in fair  value of
the Option of $1,151, $1,263 and $99, respectively.

Warrants in connection with the convertible promissory  notes

During the years ended December 31, 2012  to  2014, the Company entered into agreements  with
several investors to issue convertible promissory  notes, and  related warrants to purchase the Company’s
preference shares up to 10% of the convertible promissory notes’ principal amount concurrently for an
aggregate principal amount of $2,410. The  warrants were  freestanding instruments  and were recorded
as liabilities in accordance with ASC480. The warrants were initially recognized at fair value  with
subsequent changes in fair value recorded  in losses. In  January 2016 and February  2016, the warrants
issued  in connection with the promissory notes  were exercised for 621,637  Preferred  Shares,  which were
then  converted into 621,637 ordinary shares.  As the exercise dates were very close  to  the IPO closing
date, the respective exercise date fair  value of the warrants of  $1,148 was determined  based on the
intrinsic value, which equaled the difference between  the share price at the IPO closing date  and the
exercise price of the issued warrants. For  the years ended  December 31,  2016, 2015 and 2014, the
Company recognized a loss from the increase in fair value of $363, $563  and $127, respectively.

9. Long-term bank loan

On September 2, 2015, BeiGene Suzhou entered into a loan agreement with Suzhou Industrial

Park Biotech Development Co., Ltd. and China  Construction Bank,  to  borrow $17,284 at a  7% fixed
annual interest rate. As of December  31, 2016, the  Company has  drawn down  $17,284, which  is secured
by BeiGene Suzhou’s equipment with  a  carrying amount of $22,292 and  the  Company’s rights to a PRC
patent on a drug candidate. The loan  principal amounts of $8,642 and $8,642  are repayable  on
September 30, 2018 and 2019, respectively. Interest expense recognized for the years ended
December 31, 2016 and 2015 amounted to $851 and $140, respectively.

10. Senior promissory note

On February 2, 2011, the Company issued a senior promissory  note to Merck  Sharp &  Dohme

Research GmbH (‘‘Merck Sharp’’), an  entity that is unaffiliated with  Merck KGaA,  Darmstadt
Germany, with a principal amount of $10,000  (the  ‘‘Senior Promissory Note’’). The Senior  Promissory
Note bore interest of 8% compounding per annum  and had a  term of five years. The Company  had the
option to elect to repay in whole or in part the outstanding  principal  and  accrued interest  any time
prior to the maturity of the Senior Promissory Note.

The Senior Promissory Note was initially recorded as  a long-term liability carried at  its amortized

cost of $10,000 and subsequently accreted  to  the amount payable upon maturity using  the effective
interest method. Interest accrued as of December 31, 2016 and 2015 amounted to nil and $4,598,
respectively.

On January 26, 2016, the Company entered into a note  amendment and exchange  agreement with

Merck Sharp, pursuant to which, the maturity date  of  the Senior Promissory Note was extended to

10. Senior promissory note (Continued)

May 2, 2016 from February 2, 2016. In addition,  if the IPO occurred on  or prior to May 2, 2016,
subject  to certain limitations, the outstanding unpaid principal and interest  of the Senior Promissory
Note as of the effectiveness date of the  Company’s  IPO (the ‘‘Exchanged Balance’’)  would be
automatically exchanged, effective immediately prior  to  the closing of the IPO, into up  to  a number  of
the Company’s ordinary shares equal to the quotient of (1)  the Exchanged Balance divided by (2) the
per ordinary share public offering price  in the IPO.  The  amendments and  subsequent extinguishment of
the Senior Promissory Note did not result  in any gain  or  loss since the  conversion  rate was  set at  the
IPO Price.

On February 8, 2016, the outstanding unpaid  principal  and interest of the Senior Promissory Note
of carrying value of $14,693 were exchanged into 7,942,314 ordinary shares, computed at the  IPO Price
of $1.85 per ordinary share.

11. Convertible preferred shares

In October 2014, the Company issued 52,592,590 Series A convertible  preferred shares (the

‘‘Series A Preferred Shares’’) with a par value  of  $0.0001 per  share for cash consideration of $35,500  or
$0.68 per share. At the same time, the previously issued subordinated  convertible promissory note,
convertible promissory notes, secured guaranteed convertible promissory notes,  advances and
convertible promissory notes due to the related party  were  automatically  converted  into  64,192,927
Series A Preferred Shares in aggregate.

On April 21, 2015, the Company issued 83,205,124  Series A-2 convertible preferred  shares (the
‘‘Series A-2 Preferred Shares’’) with a par value of $0.0001 per share for cash  consideration of $97,350
or $1.17 per share.

The Series A Preferred Shares and the Series A-2 Preferred Shares are collectively referred  to  as

the ‘‘Preferred Shares.’’

The significant terms of the Preferred Shares are summarized below.

Dividends

The holders of the Preferred Shares shall be entitled to receive dividends accruing at the rate of
8% per annum. In addition, holders of the Preferred Shares shall also be  entitled to dividends on  the
Company’s ordinary shares on an as if  converted basis.

Voting rights

Each holder of Preferred Shares shall have  the right to vote the number  of  votes per ordinary
share into which their Preferred Shares could be converted,  and shall vote along  with the ordinary
shares, on all matters in respect to which  the holders of ordinary shares are  entitled to vote.

11. Convertible preferred shares (Continued)

Liquidation preference

In the event of any voluntary or involuntary liquidation,  dissolution or  winding up  of  the Company

or any deemed liquidation event as defined in the Preferred Shares agreements (‘‘Liquidation
Transaction’’), the holders of Preferred Shares then outstanding are entitled to be paid  out of the  assets
of the Company available for distribution  to  its  members before any  payment shall be made to the
holders of any other class of shares by reason of their ownership thereof, an amount per share equal to
the greater of (i) the original issue price, plus accrued but unpaid  dividends;  or (ii)  such amount per
share as would have been payable had all Preferred Shares been converted into ordinary  shares
immediately prior to such liquidation, dissolution,  winding up  or  deemed  liquidation  event.

Conversion rights

(i) Optional conversion: Each Preferred Share shall be convertible  into  the Company’s ordinary
shares at the option of the holder at any time after  the issuance date by dividing the original
issue price by the conversion price, which  is  initially equal  to  the original  issue price. All
unpaid, cumulative dividends on the Preferred  Shares shall no longer be payable.

(ii) Automatic conversion: All outstanding Preferred Shares shall automatically be converted into
ordinary shares at  the then effective  Preferred Shares conversion price upon (i) the closing of
a Qualified IPO; or (ii) the date and  time, or  the occurrence of an event, specified by vote or
written consent of the holders of at least 80.63% of  the then outstanding Preferred Shares.
Upon conversion of the Preferred Shares, all unpaid, cumulative dividends on the Preferred
Shares shall no longer be payable.

Drag-along right

In the event that each of (i) (A) Baker  Brothers  or (B) Hillhouse  BGN Holdings  Limited

(‘‘Hillhouse’’) and CB Biotech Investment Limited (‘‘CITIC PE’’) jointly; (ii) a majority of the Board of
Directors; and (iii) the holders of more than  66.66% of the then-outstanding ordinary  shares (other
than those issued or issuable upon conversion of the Preferred Shares and any  other derivative
securities) approve a sale of the Company  in writing,  then each preferred shareholder agrees to certain
joint actions to be taken to ensure such sale  of  the Company could be completed.

Accounting for Preferred Shares

The Preferred Shares were classified  as mezzanine equity as these convertible preferred shares

were redeemable upon the occurrence  of  a conditional  event (i.e. a  Liquidation Transaction). The
holders  of the Preferred Shares had  a liquidation  preference and would not receive the  same form of
consideration upon the occurrence of  the conditional  event as the holders of the ordinary shares would.
The initial carrying amount of the Series  A  Preferred Shares of $78,809 was the issue price  at the date
of issuance of $78,889, net of issuance costs of $80. The initial carrying amount of the  Series A-2
Preferred Shares of $97,275 was the issue  price at the date of issuance of $97,350, net of issuance costs
of $75.The holders of the Preferred Shares have the ability  to  convert the instrument into the

11. Convertible preferred shares (Continued)

Company’s ordinary shares. The conversion option  of the  convertible preferred shares  did not qualify
for bifurcation accounting because the conversion option is clearly and closely related  to  the host
instrument and the underlying ordinary  shares were  not publicly  traded nor  readily convertible into
cash. The contingent redemption options of the convertible preferred shares did not qualify for
bifurcation accounting because the underlying ordinary shares were  neither publicly traded nor readily
convertible into cash. There were no other embedded derivatives  that are required to be bifurcated.

Beneficial conversion features exist when the conversion price of the convertible preferred  shares is

lower than the fair value of the ordinary shares at the commitment date,  which is  the issuance date in
the Company’s case. When a beneficial conversion feature exists as of the commitment date, its
intrinsic value is bifurcated from the  carrying value of the convertible preferred shares as a  contribution
to additional paid-in capital. On the  commitment date of Series A  Preferred Shares and  Series A-2
Preferred Shares, the most favorable conversion  price used  to  measure  the beneficial conversion feature
were $0.68 and $1.17, respectively. No beneficial  conversion feature  was  recognized for the Series A
Preferred Shares and Series A-2 Preferred Shares as the fair value per ordinary share at the
commitment date were $0.28 and $0.47, respectively,  which  was less than the  most favorable conversion
price. The Company determined the fair value of ordinary shares with the assistance of an independent
third party valuation firm.

The Company concluded that the Preferred Shares  were not redeemable, and  it was not probable

that the Preferred Shares would become redeemable  because the likelihood of a Liquidation
Transaction was remote. Therefore, no adjustment was made to the  initial carrying amount of  the
Preferred Shares.

On February 8, 2016, in connection with the completion  of  the IPO,  all of the outstanding

Preferred Shares were converted into 199,990,641 ordinary shares.

to the Company at a fee of $100, and  $100, respectively.  During the year ended December 31,
2016, the shareholder, who became a  director, provided consulting services to the Company at a
fee of $100.

(2) During the years ended December 31, 2016,  2015 and 2014, senior executives advanced  nil, nil and
$103, respectively, to the Company. The  advances  bore  interest  at a  rate comparable to the  interest
rate borne by the Company on its outstanding third party debt. On  September 15, 2014,  the
Company entered into a supplemental agreement  with the senior  executives to clarify  its original
intention that the indebtedness and accrued  interest could  be  converted into  convertible preferred
shares based on the same conversion  terms  in the subordinated convertible promissory  note
agreement the Company entered into with  Merck Sharp. For the period  from January 1, 2014
through October 7, 2014, the Company repaid  advances  amounting to $1,285 and $61 in  cash and
by the issuance of 6,069,000 ordinary  shares with fair value  of $61, respectively.

(3) During the year ended December 31,  2012,  the Company issued convertible promissory  notes and

related warrants to senior executives  for an aggregate principal amount of $650. The warrants were
initially recognized at fair value of $25, with  subsequent changes in  fair value recorded in  losses.
For the years ended December 31, 2016,  2015 and 2014, the  Company recognized a loss from the
increase in fair value of $51, $80 and  $34, respectively. In  January and February 2016, the  warrants
issued in connection with the promissory notes were exercised for 82,241  Preferred  Shares,  which
were converted into 82,241 ordinary shares.  The  terms and  conditions underlying the convertible
promissory notes and related warrants were the same  as the convertible promissory notes,  and
warrants issued to all the other holders.

(4) On October 7, 2014, all outstanding  indebtedness due  to  senior executives was settled by the
issuance  of the Company’s Series A Preferred Shares with fair value  of $9,983. The  advances

outstanding (including interest expense),  and  the convertible promissory notes (including interest
expense) were converted into 13,629,629  and  1,160,426 of the Company’s Series A Preferred
Shares, respectively. The difference of $1,840 was recognized in losses as  a result of the  settlement
of indebtedness. Upon completion of  the Company’s IPO, the outstanding Series A Preferred
Shares were converted into 14,790,055 ordinary shares. The  warrants originally issued to the senior
executives in connection with the convertible promissory notes were  exercised in January  and
February 2016.

13. Research and development collaborative arrangements

The Company has developed and controls certain technology and proprietary  materials related to
its proprietary BRAF inhibitor (‘‘BRAF’’  or ‘‘BGB-283’’) and poly (ADP-ribose) polymerase inhibitor
(‘‘PARP’’ or ‘‘BGB-290’’). Upon execution of the Collaborative Arrangements,  the Company granted  to
Merck KGaA, Darmstadt Germany the exclusive right to develop  and commercialize the BRAF and
PARP  inhibitors worldwide except the PRC (‘‘Ex-PRC’’).  The Company has since retained the exclusive
right to develop and commercialize the BRAF and PARP inhibitors in the PRC, as  further described
below.

In 2013, the Company entered into a license agreement with Merck KGaA, Darmstadt Germany

on the BRAF inhibitor, which was amended and restated in  2013 and 2015, in which it  granted to
Merck KGaA, Darmstadt Germany an exclusive license to development and manufacture the  BRAF
inhibitor in the ex-PRC Territory, and  Merck KGaA Darmstadt Germany  granted the Company  an
exclusive license to develop, manufacture  and  commercialize  the BRAF inhibitor in the PRC  Territory.
Under the terms of the BRAF Collaborative  Arrangements, the Company received an upfront
non-refundable payment and upfront Phase 1 research and  development fees in  2013. Upon the dosing
of the 5th patient in 2014, the Company  received an additional Phase 1  research  and development fee.
Subsequent to the completion of the  Phase 1 research and development phase, the  Company was
eligible to receive  product development payments based on  the successful achievement of development
and  regulatory goals, commercial event payments based on  the successful achievement of
commercialization goals, and royalty  payments based  on a predetermined  percentage of Merck KGaA,
Darmstadt Germany’s aggregate annual  net sales of all products in the  Ex-PRC territories  for a  period
not to exceed ten years from the date of the first commercial  sale. In  March 2017, the  Company
regained the worldwide rights to the BRAF  inhibitor after Merck KGaA, Darmstadt Germany informed
the Company that it will not exercise the Continuation Option, and thus,  the ex-PRC BRAF
Agreement has terminated in its entirety, except for certain  provisions that will survive the  termination.
In addition, the Company is eligible for  $14,000 of additional  payments upon the successful
achievement of pre-specified milestones in the  PRC  territory.  In consideration for the licenses Merck
KGaA, Darmstadt Germany grants to  the Company, it  will pay Merck KGaA, Darmstadt Germany a
high single-digit royalty on aggregate  annual  net sales of BGB-283 products in PRC for a period not  to
exceed ten years from the date of the  first commercial sale.

In 2013, the Company entered into a license agreement with Merck KGaA, Darmstadt Germany
on the PARP inhibitor, in which it granted to Merck KGaA, Darmstadt Germany an  exclusive  license

to development and manufacture the PARP  inhibitor  in the ex-PRC Territory, and  Merck KGaA
Darmstadt Germany granted the Company  an exclusive license to develop, manufacture and
commercialize the PARP inhibitor in the PRC Territory. Under the terms  of  the PARP Collaborative
Arrangements, the Company has received an  upfront non-refundable  payment and upfront Phase 1
research and development fees in 2013. Upon the dosing of the 5th patient in  2014, the Company
received an additional Phase 1 research and development fee.  On October 1, 2015, the Company
entered into a purchase of rights agreement with Merck KGaA, Darmstadt Germany, pursuant to
which the Company purchased from Merck KGaA, Darmstadt Germany all  its exclusive rights to
develop and commercialize the PARP inhibitors in the  Ex-PRC territories for  a consideration of
$10,000, and reduced the future milestone payments the Company  is eligible to receive under the PRC
license  agreement. Upon the execution of the purchase of rights agreement,  Merck KGaA,  Darmstadt
Germany has no further rights and obligations  in the  Ex-PRC territories under the PARP Collaborative
Agreements. In connection with such purchase of  rights,  the Company also provided  Merck KGaA,
Darmstadt Germany with global access  to  the Company’s PARP supplies for Merck  KGaA, Darmstadt
Germany’s combination clinical trials at any time during  the period from October 1,  2015 until the  first
regulatory approval received for the commercialization of  the Company’s PARP inhibitor  in certain
major countries.

The Company determined that the deliverables related to the collaboration  with Merck  KGaA,
Darmstadt Germany, including the licenses  of exclusive rights  granted to Merck KGaA, Darmstadt
Germany, as well as the Company’s performance obligations to provide  Phase 1 research and
development services, would be accounted for  as separate  units of accounting.  This determination was
made because each deliverable has stand-alone  value to Merck KGaA, Darmstadt Germany  and the
arrangement does not include a right of return  for any deliverable. The Company recognized  the
upfront non-refundable license fee upon the  delivery of the license right and the reimbursement  of  the
Phase 1 research and development services on a straight-line basis  over the performance  period ranging
from one to three years from the execution date of the respective collaboration arrangements.  The
Company has made an allocation of revenue  recognized  as  collaboration revenue between the license
and  the services. This allocation was  based upon  the relative selling price determined  using the BESP
of each deliverable. Management utilized a discounted cash-flow model and  considered a  variety of
factors in determining the best estimate of selling price  of each deliverable, including, but  not  limited
to: the rights that Merck KGaA, Darmstadt Germany was granted under the license, the early stage of
the product candidates, the relative risks of  successful  development of the product candidates, the  size
of the potential market for the product  candidates, competing products and  the life-cycle of  the
product candidates. There have been no significant changes in either the selling  price or the method or
assumptions used to determine the selling price  for a specific  unit of accounting during  any of the
periods presented.

The Company did not elect the milestone method of revenue  recognition  under ASC 605-28.
Therefore, the additional Phase 1 research  and  development fees related to the 5th patient  dosing were
combined with the other consideration  received in the arrangement, being the license and  Phase 1
research and development reimbursements. Based on the  above, the additional fee  related to the

13. Research and development collaborative arrangements (Continued)

5th patient dosing was allocated based on  the relative selling price percentages  determined for  the
separate units of account at the inception of  the Collaborative  Arrangements. Upon completion of the
5th patient dosing, the fee allocated to the license was recognized immediately and the fee allocated  to
research and development reimbursements was recognized on a straight-line basis  over the performance
period  under the cumulative catch-up approach. The  5th patient dosing was completed, and the
Company received $5,000 for BRAF and $9,000 for  PARP on May 14, 2014  and September 17, 2014,
respectively.

The repurchase consideration of $10,000 associated with the reacquisition of the  rights to the
PARP  inhibitor was charged to research and development expenses as incurred because  the rights have
no alternative future use. As Merck KGaA, Darmstadt  Germany has no further  rights in  the Ex-PRC
territories under the PARP Collaborative Agreements,  the advances previously received from Merck
KGaA, Darmstadt Germany amounting  to  $3,018 were offset against  the  aforementioned repurchase
consideration.

Upon achievement of a 5th patient dosing  development based  target in the PRC territory  under

the BRAF Collaborative Arrangements on November  12, 2015, the Company recognized $4,000  of
research and development revenue. No other  development based targets  have been achieved and  none
of the products have been approved. Hence, no revenue has been  recognized  related to royalties  or
commercial event based targets in any of the periods presented. In addition, no  payments have  been
made to the collaborator for any of the periods presented.

In addition to the collaboration with  Merck KGaA, Darmstadt  Germany, the  Company also
provided research and development services to other customers in the PRC amounting to nil,  nil and
$81, respectively, for the years ended December 31, 2016,  2015 and  2014.

The effects of all convertible preferred shares, share options, restricted shares, warrants and  option

to purchase ordinary or preferred shares were  excluded from the  calculation  of  diluted earnings per
share as their effect would have been  anti-dilutive during the years ended December 31,  2016 and  2015.

The effects of all convertible preferred shares, share options, restricted shares, subordinated

convertible promissory note, convertible  promissory notes, the secured  guaranteed  convertible
promissory notes, warrants and option to purchase ordinary or  preferred shares  were excluded  from the

2016 Share option and incentive plan

On January 14, 2016, in connection with the IPO, the board  of directors and  shareholders of the

Company approved the 2016 Share Option  and  Incentive Plan  (the  ‘‘2016 Plan’’),  which became
effective on February 2, 2016. The Company  initially reserved 65,029,595  ordinary shares for the
issuance of awards under the 2016 Plan plus  any  shares available under the 2011  Plan and not subject
to any outstanding options as of the effective date  of the  2016  Plan.  The  2016 Plan provides for an
annual increase in the shares available  for issuance thereunder, to be added on  the first day of each
fiscal year, beginning with the year ending December 31, 2017 and continuing until  the expiration of
the 2016 Plan, equal to the lesser of  (i) five percent (5%) of the outstanding  shares of the  Company’s
common stock on the last day of the immediately  preceding fiscal year or (ii) such  number of shares
determined by the  board of director or  the compensation committee. This number  is subject to
adjustment in the event of a share split, share  dividend  or other change in  the Company’s
capitalization. In addition, options cancelled  or forfeited under the 2011 Plan  will  also be available for
issuance under the 2016 Plan.

During the years ended December 31, 2015  and  2014, the Company granted 15,663,600 and
3,766,000 options to employees, as well  as 1,950,000 and 125,000 options  to non-employees under the
2011 Plan, respectively.

In January 2016, the Company granted 1,685,152 options to  employees and  732,000 options to

consultants, with an exercise price of  $1.85 per ordinary share under the 2011  Plan.

On February 8, 2016, the Company granted 460,626 options with  an exercise price  of  $2.43 per

ordinary share under the 2016 Plan.

On May 3, 2016, the Company granted 2,376,000  options with an  exercise price of $2.05  per

ordinary share and 475,000 restricted  ordinary shares  under  the 2016 Plan.

On October 12, 2016, the Company granted 20,000  and 10,400 options  to employees  under the

2016 Plan, with exercise price of $0.5 per share  and  $1.85 per  share, respectively.

For the period from July 1, 2016 through December 31,  2016,  except for the 30,400  options
granted on October 12, 2016 (mentioned above),  the Company  granted an  aggregate  of 30,764,961
options to employees, 2,872,080 options to consultants,  and 600,000 restricted ordinary shares to
employees, under the 2016 Plan, with an  exercise price  per  ordinary share equal to  1⁄13 of the closing
price of the Company’s ADS quoted  on the  NASDAQ Stock Exchange on the respective grant  date.

During  the years ended December 31, 2016,  2015 and 2014, the  Company granted nil,  11,400,500

and nil options to employees and nil,  3,800,167 and nil  options  to  non-employees outside of the
Company’s 2011 Plan and 2016 Plan.

Generally, options  have a contractual  term of 10 years and vest over a three- to five-year period,

with the first tranche vesting one calendar year after  the grant date or the service relationship start
date  and the remainder of the awards  vesting on a monthly basis  thereafter. Restricted shares  vest over

As of December 31, 2016, share-based  awards to purchase 77,079,743 ordinary  shares were
outstanding and share-based awards to purchase 34,712,601 ordinary shares were available for  future
grant  under the Plan.

Modification

On October 1, 2015 (‘‘Modification Date’’), a consultant  surrendered 1,000,000  options in exchange

for a reduction of  the vesting period  (‘‘Modified Option Agreement’’). The fair value of the options
immediately after the modification was higher  than that immediately  before  the modification. The total
incremental compensation cost for the  modification of $81 was recognized on Modification Date.
Subsequently, on November 1, 2015  (‘‘Date  of the  Change in Employment Status’’), the consultant
became  an employee of the Company. Under the terms  of the Modified Option  Agreement, the
individual retains the same vesting terms; hence, there  is no  modification  to  account for.  The  fair value
of the options to the consultant has been re-measured on  the Date of the Change in  Employment
Status and compensation charges have  been accounted for prospectively over the remaining vesting
period.

Upon the completion of the Company’s IPO on  February 8, 2016,  a consultant became a  member
of the Company’s board of directors. Under the terms  of  the original option agreement,  the individual
retains  the option  grants on a change in  status; hence,  there is  no modification to account for. The fair
value of the options granted by the Company to the consultant has  been re-measured  as of February 8,
2016 and compensation charges have  been  accounted  for prospectively over the remaining vesting
period.

There were no other modifications to the  Company’s  share option arrangements  for the  periods

presented.

Fair value of options

The binomial option-pricing model was applied in determining  the estimated fair value of the
options granted. The model requires  the input of highly subjective  assumptions including the estimated
expected stock price volatility and, the exercise multiple for which employees  are likely  to  exercise
share options. For expected volatilities, the  trading history and observation  period of  the Company’s
own share price movement has not been long enough to match the  life  of the share option.  Therefore,
the Company has made reference to the historical price volatilities of ordinary shares  of  several
comparable companies in the same industry as the  Company. For  the  exercise multiple, the  Company
was not able to develop an exercise pattern as  reference, thus  the  exercise multiple is based on
management’s estimation, which the Company  believes  is representative of  the future exercise  pattern
of the options. The risk-free rate for  periods within the contractual life of the option is based on  the
U.S. Treasury Bills yield curve in effect at the time of grant.  Prior to the  completion  of the Company’s
initial public offering, the estimated fair value  of the  ordinary shares, at the  option grant  dates, was
determined with assistance from an independent third party  valuation  firm, and  the Company’s
management was ultimately responsible  for the  determination of  the  estimated  fair value of its ordinary

(Amounts in thousands of U.S. Dollar (‘‘$’’)  and Renminbi (‘‘RMB’’),
except for number of shares and per share data)

18. Restricted net assets

The Company’s ability to pay dividends may depend  on  the Company  receiving distributions of

funds from its PRC subsidiaries. Relevant PRC  statutory  laws and regulations permit  payments of
dividends by the Company’s PRC subsidiaries only out  of  its retained  earnings, if any,  as determined in
accordance with PRC accounting standards and regulations.  The results of operations  reflected in the
consolidated financial statements prepared in accordance with GAAP differ from  those reflected in  the
statutory financial  statements of the Company’s  PRC subsidiaries.

In accordance with the company law of the PRC,  a  domestic enterprise is required to provide
statutory reserves of at least 10% of its  annual after-tax profit  until such reserve has reached 50%  of  its
respective registered capital based on the  enterprise’s PRC statutory accounts. A  domestic  enterprise  is
also required to provide discretionary surplus reserve, at the discretion of the Board of Directors,  from
the profits determined in accordance  with the enterprise’s PRC  statutory accounts.  The  aforementioned
reserves can only be used for specific purposes and are not  distributable as  cash dividends. The
Company’s PRC subsidiaries were established as domestic invested enterprises  and therefore  were
subject  to the above mentioned restrictions on distributable profits.

During the years ended December 31, 2016,  2015 and 2014, no appropriation  to  statutory reserves

was made because the PRC subsidiaries had substantial losses during such  periods.

As a  result of these PRC laws and regulations including the requirement to make annual
appropriations of at least 10% of after-tax income and  set aside as general reserve fund prior  to
payment of dividends, the Company’s PRC subsidiaries are restricted in their ability to transfer a
portion of their net assets to the Company.

Foreign exchange and other regulation in the  PRC may further restrict the Company’s PRC
subsidiaries from transferring funds to the  Company in the form of dividends,  loans and advances. As
of December 31, 2016 and 2015, amounts restricted  are  the net assets of  the Company’s PRC
subsidiaries, which amounted to $9,955  and $3,383, respectively.

19. Employee defined contribution plan

Full time employees of the Company in the PRC  participate in a  government mandated  defined
contribution plan, pursuant to which certain  pension benefits, medical  care,  employee housing  fund  and
other  welfare benefits are provided to  employees. Chinese labor regulations require that the  Company’s
PRC subsidiaries make contributions to the government  for  these  benefits based on certain percentages
of the employees’ salaries. The Company  has no legal obligation for the benefits beyond the
contributions made. The total amounts for such  employee benefits,  which were expensed as incurred,
were $2,148, $1,443 and $1,030 for the  years  ended December 31, 2016,  2015 and  2014, respectively.
During the year ended December 31,  2016, the Company implemented a defined contribution  401(k)
savings plan (the ‘‘401(k) Plan’’) for U.S. employees.  The 401(k) Plan  covers all U.S. employees, and
allows participants to defer a portion of their annual  compensation  on a pretax basis. In addition, the
Company implemented a matching contribution to the 401(k) Plan, matching 50% of an employee’s
contribution up to a maximum of 3%  of  the participant’s  compensation.  Company contributions  to  the
401(k) plan totaled $0.1 million in the  year ended December 31, 2016. The  Company did  not  have a

401(k) matching contribution in 2015 or  2014. Employee benefits for the remaining subsidiaries were

20. Commitments and contingencies

Operating lease commitments

The Company leases office and manufacturing facilities  under  non-cancelable  operating leases

expiring on different dates in the United  States and China. Payments under operating  leases are
expensed on a straight-line basis over  the periods of their respective leases, and the terms of the leases
do not contain rent escalation, contingent  rent,  renewal, or purchase options.

There are no restrictions placed upon the Company by  entering  into  these  leases. Total expenses

under these operating leases were $1,974, $1,136  and  $940 for the years ended December 31,  2016,
2015 and 2014, respectively.

Future minimum payments under non-cancelable operating  leases consist  of  the following as of

December 31, 2016:

increasing range thereafter will not exceed 5%  of  the previous  yearly service charges.  Suzhou  Industrial
Park Administrative Committee will  pay  full monthly  rent  for  the first  three years and 50% of  the
monthly rent for the following two years.

(1) Per common share amounts for the  quarters and full years have been calculated separately.
Accordingly, the sum of quarterly amounts may  not  equal the annual  amount because of
differences in the weighted average common  shares outstanding during each period, principally due
to the effect of share issuances by the Company  during the year.

22. Subsequent events

Manufacturing Facility in Guangzhou

On March 7, 2017, BeiGene (Hong Kong) Co., Limited (‘‘BeiGene HK’’), a  wholly owned

subsidiary of the Company, and Guangzhou  GET Technology Development Co., Ltd. (‘‘GET’’),  entered
into a definitive agreement to establish a  commercial  scale biologics manufacturing  facility  in
Guangzhou, Guangdong Province, PRC.  The joint venture,  (the ‘‘JV Company’’), BeiGene
Biologics Co., Ltd., will also provide funding  for  research  and development  of biologic drug candidates
in the PRC.

22. Subsequent events (Continued)

Under the terms of the Equity Joint  Venture Contract, BeiGene HK will make an initial  cash
capital contribution of RMB200,000  and a subsequent contribution of one or more  biologics assets  in
exchange for a 95% equity interest in the JV Company. GET will provide a  total  of RMB1,000,000
cash to the JV Company including a 5% equity interest in the JV  Company and  a shareholder loan
(the ‘‘Shareholder Loan’’) to the JV Company.  The  term of the  Shareholder Loan is  72 calendar
months, commencing from the actual  draw down date indicated  in the receipt of  the Shareholder Loan,
which has not yet occurred. Interest accrues at 8% per annum. No accrued  interest is due and  payable
prior to the repayment of the principal or the debt-to-equity conversion. The  Shareholder Loan may be
prepaid or converted in full or partially into a mid-single digit percentage equity interest  in the
JV Company prior to its maturity date pursuant to the terms of the  JV Agreement upon the
achievement of certain regulatory milestones. The Shareholder Loan can only be used for the
JV Company, including the construction and operation of the biologics  manufacturing facility and
research and development and clinical trials  to  be  carried  out by the  JV  Company. If  the JV Company
does not use the Shareholder Loan proceeds for the specified purposes, GET may  be  entitled to
certain liquidated damages. In the event of an early termination of the JV  Agreement, the Shareholder
Loan will become due and payable at  the time of termination of the JV Agreement. Under the  terms
of the Capital Increase Agreement, BeiGene  HK will  contribute RMB200,000  as cash capital
contributions over a three-year period commencing March 31, 2017. GET will contribute  its full  cash
contribution, including the Shareholder Loan,  not  later than  March 31,  2017.

The JV Company will establish a biologics manufacturing  facility in  Guangzhou (the ‘‘Factory’’)

through  a wholly-owned subsidiary (the ‘‘Factory Sub’’) to manufacture biologics, with  a registered
capital of RMB1,000,000. The Factory Sub expects to acquire at  least 100,000 square meters of land for
the Factory in the Sino-Singapore Guangzhou Knowledge City and  borrow  RMB1,000,000 in the  form
of a commercial bank loan for the purpose  of  the construction  and operation of the  Factory and
expects to receive certain interest subsidies for  commercial loan interest payment(s), subject to
limitation.

Collaboration with Merck KGaA, Darmstadt Germany

In March 2017, the Company regained the  worldwide rights  to  BGB-283  after Merck KGaA,
Darmstadt Germany informed the Company  it will  not  exercise the Continuation  Option in  its former
exclusive license to commercialize and  manufacture  BGB-283 outside of China.

PROXY STATEMENT
FOR THE 2017  ANNUAL GENERAL  MEETING OF  SHAREHOLDERS

GENERAL INFORMATION

This Proxy Statement is furnished in connection  with the solicitation of proxies by the Board  of

Directors of BeiGene, Ltd. (the ‘‘Board of Directors’’) for use  at  its  2017 Annual  General Meeting of
Shareholders (the ‘‘Annual Meeting’’)  to  be held on June 1, 2017  at 2:30 p.m. local time at the  offices
of Ernst & Young at EY Tower, 100 Adelaide St. W, Toronto  Canada,  for  the purpose of  considering
and, if thought fit, passing the resolutions specified in the Notice of Annual General Meeting.  This
Proxy Statement is being mailed to shareholders  on or  about April  27, 2017.

For a  proxy to be effective, it must be properly executed and dated and lodged  (together with a
duly signed and dated power of attorney or other authority (if any)  under which  it is executed (or  a
notarially certified copy of such power of  attorney or other authority)) at  the offices  of  our  registrar,
Mourant Ozannes Corporate Services (Cayman) Limited (the ‘‘Registrar’’) so as to be received before
the time of the Annual Meeting. Each  proxy properly  tendered will, unless otherwise  directed by the
shareholder, be voted FOR the director  nominees described in this Proxy Statement,  FOR the
appointment of Ernst & Young Hua Ming LLP as the Company’s independent  registered  public
accounting firm for the year ending December 31,  2017, and  at  the discretion of the proxy  holder(s)
with regard to all other matters that may  properly  come before the meeting.

We  will pay all of the costs of soliciting proxies. Our directors, officers and employees  may also
solicit proxies; however, we will not pay them additional  compensation for  any of  these services.  Proxies
may be solicited by telephone, facsimile,  personal solicitation or otherwise.

In this Proxy Statement, the terms ‘‘BeiGene,’’ ‘‘we,’’ ‘‘us,’’ and  ‘‘our’’ refer to BeiGene, Ltd and

its  subsidiaries. The mailing address  of our principal executive  offices  is c/o Mourant Ozannes
Corporate Services (Cayman) Limited,  94  Solaris Avenue, Camana Bay, Grand Cayman KY1-1108,
Cayman Islands.

EXPLANATORY NOTE

We  are an ‘‘emerging growth company’’ under applicable  United States federal securities  laws  and

therefore are permitted to take advantage of reduced  public  company  reporting requirements. As  an
emerging growth company, we provide in this Proxy  Statement the disclosure  permitted under the
Jumpstart Our Business Startups Act of 2012, including the compensation disclosures  required of  a
‘‘smaller reporting company,’’ as that term is defined in  Rule  12b-2 under the  U.S. Securities Exchange
Act of 1934, as amended (the ‘‘Exchange  Act’’).  In addition, as  an emerging  growth company, we are
not required to conduct votes seeking  approval, on an advisory basis, of  the compensation of our
named executive officers or the frequency  with which such votes must be conducted. We will remain an
‘‘emerging growth company’’ until the  earliest of (1) the last  day  of the fiscal  year in which we have
more than $1.0 billion in annual revenue; (2) the date  we qualify as  a  ‘‘large accelerated  filer,’’  with at
least $700 million of equity securities  held  by non-affiliates; (3)  the issuance, in any three-year  period,
by BeiGene of more than $1.07 billion in non-convertible debt securities; and (4)  December 31, 2021.

Shareholders Entitled to Vote; Record Date

Only holders of record of our ordinary shares, par value $0.0001  per  share, at the close  of  business
on April 20, 2017, Cayman Islands time (the ‘‘record date’’)  are entitled to  notice  of,  and to attend and
to vote at, the Annual Meeting. As of  the  close of business on  the record date, we  had outstanding
518,602,349 ordinary shares, all of which are entitled to vote with respect to all matters to be acted
upon at the Annual Meeting. On the  record date,  approximately 256,548,929 ordinary  shares were held

1

in the name of Citibank, N.A. (the ‘‘Depositary’’) as  depositary for the ADS,  which issues company-
sponsored American Depositary Receipts  (‘‘ADRs’’),  evidencing ADSs that in turn each represent 13 of
our  ordinary shares. Each shareholder of record is entitled to one  vote for  each  ordinary share held by
such shareholder.

Quorum

We  are an exempted company incorporated in  the Cayman  Islands with limited  liability,  and our
affairs are governed by our memorandum  and articles  of  association, the  Companies Law  (as  amended)
of the Cayman Islands, which we refer to as the Cayman Companies Law, and the common  law  of  the
Cayman Islands.

The quorum required for a general meeting of shareholders  at which  an ordinary resolution is
proposed consists of such shareholders present in person  or by proxy who  together  hold  shares carrying
the right to at least a simple majority  of all votes capable of being exercised on a poll. The quorum
required for a general meeting at which a special  resolution  is proposed  consists of such shareholders
present  in person or by proxy who together  hold  shares carrying the right  to  at least two-thirds  of  all
votes capable of being exercised on a  poll.

An ordinary resolution to be passed by the shareholders  requires  the affirmative vote of a simple

majority of the votes cast by the shareholders entitled to vote who  are present in  person or by proxy  at
a general meeting, while a special resolution requires the affirmative vote of at least two-thirds of the
votes cast by the shareholders entitled  to  vote who  are present in person or by proxy at a general
meeting  (except for certain types of winding  up of the company, in which case the required majority to
pass a special resolution shall be 100%). A special  resolution  is required for  important matters such  as
a change of name and amendments to  our  articles.  Our shareholders  may effect certain changes  by
ordinary resolution, including increasing  the amount of our  authorized share capital, consolidating and
dividing all or any of our share capital  into  shares of  larger amounts than  our existing shares  and
cancelling any authorized but unissued  shares.

Voting

Persons who hold our ordinary shares directly on  the record date (‘‘record holders’’)  (1) must

return  a proxy card (a) by mail to the offices  of  the Registrar: Mourant Ozannes Corporate Services
(Cayman) Limited, 94 Solaris Avenue,  Camana Bay,  Grand Cayman  KY1-1108, Cayman  Islands, or
(b) by email at CaymanAdmin@mourantozannes.com or (2)  attend  the  Annual  Meeting in  person in
order to vote on the proposals. Persons who own  our  ordinary  shares indirectly on the record date
through a brokerage firm, bank or other  financial institution, including persons  who own our ordinary
shares in the form of ADSs through  the  Depositary (‘‘beneficial owners’’) must return a  voting
instruction form to have their shares or the shares underlying  their ADSs, as the  case may be, voted  on
their behalf. Brokerage firms, banks or  other financial institutions that do not receive  voting
instructions from beneficial owners may either vote these  shares  on behalf of the  beneficial owners or
return  a proxy leaving these shares un-voted (a ‘‘broker  non-vote’’).

ADR holders are not entitled to vote directly at  the Annual Meeting,  but the Deposit  Agreement,
dated as of February 5, 2016, as amended  (the  ‘‘Deposit Agreement’’), exists among the Depositary,  the
Company and the holders of ADRs pursuant  to  which registered holders  of  ADRs  as of the record
date  are  entitled to instruct the Depositary how to exercise  voting rights pertaining  to  the ordinary
shares so represented. The Depositary has agreed  that it will endeavor,  insofar as  practicable  and
permitted under applicable law and the  provisions of the Deposit Agreement, to vote (in person  or by
delivery to BeiGene of a proxy) the ordinary shares registered  in the name of the  Depositary in
accordance with the voting instructions received  from the ADR holders.  If the Depository does  not
receive instructions from a holder, such  holder shall be deemed, and the Depository shall (unless

2

otherwise specified in the notice distributed to holders of  ADRs) deem such holder, to have instructed
the Depository to give a discretionary proxy to a person  designated by us to vote the ordinary shares
represented by such holders’ ADSs, provided that  no such  discretionary  proxy shall be given  by  the
Depositary with respect to any matter to be voted upon  which we inform  the  Depositary that (a) we do
not wish such proxy to be given, (b)  substantial opposition exists, or (c)  the  rights of holders  of
ordinary shares may be materially adversely affected. In  the event that the  instruction  card is executed
but does not specify the manner in which  the ordinary shares represented are to be voted (i.e., by
marking a vote ‘‘FOR’’, ‘‘AGAINST’’ or any other option), the Depositary  will  vote  in respect of each
proposal as recommended by the Board which  is described in the Notice of Annual General Meeting.
Instructions from the ADR holders must  be sent to the  Depositary so that  the instructions are  received
by no later than 10:00 a.m. New York  time on May  23, 2017.

Abstentions and broker non-votes will be counted for the purpose  of  determining the presence or
absence of a quorum, but will not be counted for the purpose of determining the  number of votes  cast
on a given proposal.

We  have retained the Registrar to hold and maintain our register of members. The Registrar will
be engaged by us to take delivery of completed  proxy forms posted to it  in accordance with the  details
above.

We  encourage you to vote by proxy by mailing or emailing  an executed proxy card. Voting  in
advance  of the meeting will ensure that  your  shares will be voted  and reduce the likelihood  that  we will
be forced to incur additional expenses  soliciting proxies for the Annual Meeting. Any record holder of
our  ordinary shares may attend the Annual  Meeting in  person and  may revoke the  enclosed form of
proxy at any time by:

(cid:129) executing and delivering to the Registrar a later-dated  proxy by mail  or  email pursuant to the

instructions above; or

(cid:129) voting in person at the Annual Meeting.

Beneficial owners of our ordinary shares and ADSs representing our ordinary shares  who wish to
change or revoke their voting instructions should contact their  brokerage  firm, bank or other financial
institution or the Depositary, as applicable, for information on how to do so. Generally, however,
beneficial owners of our ordinary shares  and ADSs representing our  ordinary shares who wish to
change or revoke their voting instructions may do so  until 10:00 a.m.  New York time  on May 23, 2017.
Beneficial owners who wish to attend the Annual Meeting and vote in person  should contact their
brokerage firm, bank or other financial  institution  holding  our ordinary shares on  their  behalf in order
to obtain a ‘‘legal proxy’’ which will allow  them to both attend the meeting and vote in person.  Without
a legal proxy, beneficial owners cannot  vote at the Annual Meeting because their brokerage  firm,  bank
or other  financial institution may have already  voted or returned a broker non-vote on their  behalf.
Record holders of ADSs who wish to  attend  the Annual  Meeting  and  vote in person should contact the
Depositary (and beneficial owners wishing  to  do  the same  should contact their brokerage  firm,  bank  or
other financial institution holding their ADSs) to cause their ADSs  to  be  cancelled and  the underlying
shares to be withdrawn in accordance with the terms and conditions of the Deposit Agreement so  as to
be recognized by us as a record holder  of  our  ordinary  shares.

Expenses of Solicitation

We  are making this solicitation and will  pay  the entire cost of preparing and distributing the proxy

materials and soliciting votes. If you choose to access the proxy  materials  over the Internet, you are
responsible for any Internet access charges that you may incur.  Our officers, directors and employees
may, without compensation other than their  regular compensation, solicit proxies through  further
mailings, personal conversations, facsimile transmissions,  emails,  or otherwise.  Proxy solicitation
expenses that we will pay include those for  preparation, mailing, returning, and tabulating the  proxies.

Procedure for Submitting Shareholder Proposals

The Cayman Companies Law provides shareholders  with only limited rights  to  requisition a
general meeting and does not provide  shareholders with a  right to put any proposal before a general
meeting.  However, these rights may be provided in  a company’s articles  of  association. Our articles
allow our shareholders holding not less than  a simple  majority of the  voting rights  entitled to vote at
general meetings to requisition an extraordinary  general meeting  of  our shareholders, in  which case our
Board of Directors is obliged to convene  an extraordinary general meeting  and to put the  resolutions
so requisitioned to a vote at such meeting. However, our shareholders  may  propose  only  ordinary
resolutions to be put to a vote at such meetings and shall  have no  right to propose resolutions with
respect to the election, appointment or removal  of directors.  Our articles  provide no  other  right to put
any proposals before annual general meetings or extraordinary  general meetings.  As a  Cayman Islands
exempted company, we are not obligated  by  law  to  call shareholders’ annual general meetings.
However, our corporate governance guidelines require us to  call such meetings  every  year to the  extent
required by the stock exchange listing rules.

Shareholders may present proper proposals for inclusion in our proxy statement and for
consideration at our next annual general meeting of shareholders  by submitting  their  proposals in
writing to us in a timely manner. In order  to  be  considered for inclusion in the proxy statement for  the
2018 annual general meeting of shareholders, shareholder  proposals must be received at our principal
executive offices no later than December 26, 2017, and  must otherwise comply  with the requirements of
Rule 14a-8 of the Exchange Act. Any shareholder proposal for the annual general meeting of
shareholders in 2018, which is submitted outside the processes of  Rule 14a-8, shall be considered
untimely unless received by the Company in writing no  later than March 13,  2018. If the  date of the
annual meeting is  moved by more than  30  days from the date  contemplated  at the time of the  previous
year’s proxy statement, then notice must be received within  a reasonable time before we  begin  to  print
and send proxy materials. If that happens, we will publicly  announce the  deadline for  submitting a
proposal in a press release or in a document  filed with the SEC.  A copy of all notices of proposals by
shareholders should be sent to us at c/o Mourant Ozannes Corporate Services (Cayman) Limited,
94 Solaris Avenue, Camana Bay, Grand  Cayman KY1-1108,  Cayman Islands.

OVERVIEW OF PROPOSALS

This Proxy Statement contains three proposals requiring shareholder action.  Proposals  1 and 2
request the election of two directors  to  the Board of Directors.  Proposal 3 requests the  ratification of
the appointment of Ernst & Young Hua Ming LLP as our independent registered public accounting
firm for the fiscal year ending December 31,  2017. Each  of  the proposals  is discussed in  more detail in
the pages that follow.

PROPOSALS 1 AND 2
ELECTION OF DIRECTORS

Our articles provide that persons standing  for election  as directors at a duly  constituted general
meeting  with requisite quorum shall be elected  by  an ordinary resolution  of our  shareholders, which
requires the affirmative vote of a simple  majority of the votes  cast  on the  resolution  by  the
shareholders entitled to vote who are  present  in person or by  proxy  at  the meeting. Our  articles further
provide that our Board of Directors will  be divided into three groups designated  as Class I,  Class  II
and Class III with as nearly equal a number of directors in  each group as  possible. Directors assigned
to Class  I shall initially serve until the  first annual general meeting  of shareholders following the
effectiveness of our articles upon completion  of our initial  public offering (the ‘‘Articles Effectiveness
Date’’); directors assigned to Class II shall  initially  serve until  the second annual  general meeting  of
shareholders following the Articles Effectiveness Date; and directors assigned to Class III  shall initially
serve until the third annual general meeting  of  shareholders following the Articles Effectiveness Date.

4

Commencing with the first annual general meeting of shareholders following the Articles  Effectiveness
Date, each director of each class the term  of which  shall  then expire  shall, upon  the expiration of  his or
her term, be eligible for reelection at such annual general meeting to hold office for  a three-year term
and until such director’s successor has been duly elected. Our articles provide that, unless otherwise
determined by shareholders in a general meeting, our Board  will consist of not less than three
directors. We have no provisions relating  to retirement  of  directors upon reaching a specified  age.

In the event of a vacancy arising from the resignation  of a former  director or  as an addition to the

existing board, our Board of Directors  may, by the  affirmative vote  of a simple majority of the
remaining directors present and voting at  a board meeting, appoint  any person to be a director.

For so long as our shares or ADSs are listed  on NASDAQ, our directors  are required to comply

with the director nomination procedures of the NASDAQ Stock Market Rules, and  our  Board is
required to include at least such number of independent directors the NASDAQ  Stock Market Rules
requires.

The terms of the Class I directors are  scheduled to expire  on the date of the  2017 Annual

Meeting. Based on the recommendation of  the Nominating and Corporate Governance Committee of
the Board of Directors, the Board of Directors’ nominees for election by  the  shareholders are current
Class I members: Timothy Chen and  John V.  Oyler. If elected, each nominee will serve as a director
until the annual general meeting of shareholders in 2020 and until  his successor is duly elected and
qualified, subject to his earlier resignation  or removal.  Ke  Tang,  who currently is  a Class I  director,
notified us of his decision not to stand  for re-election  to  the Board  of  Directors when his current term
expires at the Annual Meeting. Mr. Tang  will continue  to  serve  as a member of the Board of Directors
and a member of the Audit Committee  until the  Annual Meeting.

The names of and certain information about the directors in each  of  the three  groups are set forth

below. There are no family relationships  among any of our directors  or executive officers.

The proxy in the form presented will  be voted,  unless otherwise indicated, for the election of  the
Class I director nominees to the Board  of Directors. If any of the  nominees should  for any reason be
unable or unwilling to serve at any time prior to the  Annual Meeting, the  proxies will be voted for the
election of a substitute nominee designated by  the Board of Directors.

PROPOSAL  3

RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

On the recommendation of the Audit  Committee of the Board of Directors (the ‘‘Audit

Committee’’), the Board of Directors  has  appointed Ernst & Young Hua Ming LLP as  the Company’s
independent registered public accounting  firm for the fiscal year ending December 31, 2017. The Board
of Directors recommends that shareholders vote  for ratification of this appointment. If this  proposal is

the appointment is ratified, the Audit Committee  may, in its discretion, direct the appointment of a
different independent registered accounting firm  at any time during the year if the Audit Committee
determines that such a change would  be  in our shareholders’ best interests.

Ernst & Young Hua Ming LLP has audited our financial  statements for the fiscal years ended

available telephonically at the Annual Meeting  and  available to respond to appropriate questions. They

independent auditor to render any audit  or non-audit service  unless either the service is  approved in
advance  by the Audit Committee or  the  engagement to render the  service  is entered  into  pursuant  to
the Audit Committee’s pre-approval  policies and  procedures.  The Audit Committee pre-approved all
services performed since the pre-approval policy was adopted.

The approval of Proposal 3 requires that  a simple  majority of  the  votes cast by the shareholders
entitled to vote who are present in person or by proxy  vote  in favor of this proposal. Shares that are

CERTAIN RELATIONSHIPS AND RELATED-PARTY TRANSACTIONS

Other than compensation arrangements, we  describe below  transactions and series of similar

transactions, since January 1, 2016, to which we were  a party or will  be  a  party, in which:

(cid:129) the amounts involved exceeded or  will exceed $120,000; and

(cid:129) any of our directors, executive officers  or holders of more  than 5% of our share capital,  or any
member of the immediate family of the foregoing persons, had or will  have a direct or indirect
material interest.

In connection with the completion of  our initial  public  offering,  we adopted a related party
transactions policy that requires all future transactions between us  and any director, executive officer,
holder of 5% or more of any class of our capital shares  or any  member of the immediate family of, or
entities affiliated with, any of them, or any other related persons (as defined in  Item 404 of
Regulation S-K) or their affiliates, in  which the amount involved is equal  to  or greater than $120,000,
be approved in advance by our Audit Committee. Any request for such a  transaction must first be
presented to our Audit Committee for review, consideration and  approval. In approving or rejecting
any such proposal, our Audit Committee is  to  consider the  relevant facts  and circumstances available
and deemed relevant to the Audit Committee, including, but not limited to, the  extent of the related
party’s interest in the transaction, and  whether the transaction  is on terms no less favorable to us  than
terms we could have generally obtained from an unaffiliated third party under the same or  similar
circumstances.

Certain of the transactions described below were entered  into  prior to the adoption  of  this  written

policy but each such transaction was approved  by  our Board of  Directors. Prior to our Board  of
Directors’ consideration of a transaction  with a  related person,  the material facts as to the related
person’s relationship or interest in the  transaction were disclosed to our Board  of  Directors, and the
transaction was not approved by our  Board of  Directors unless  a majority of  the directors  approved the
transaction.

We  believe that all of the transactions described below were made on terms  no less favorable  to us

than could have been obtained from  unaffiliated  third  parties. Compensation arrangements  for our
directors and named executive officers  are  described in  the section of this Proxy Statement titled
‘‘Executive Compensation.’’

Consulting Arrangements

Donald W. Glazer, a member of our Board of Directors,  has been  providing strategic consulting
services to our company since our inception in 2010.  As full compensation for his  consulting  services,
on November 24, 2010, in connection  with the  initial formation of our company,  we issued 4,000,000
ordinary shares to  Mr. Glazer at $0.0001 per share to vest over five years. Those  shares are  fully
vested. We also reimbursed Mr. Glazer for  the out  of pocket  expenses incurred in connection with his
consulting services.

Dr. Xiaodong Wang, our Founder, Chairman  of the Scientific Advisory Board and director, has
been providing scientific and strategic  advisory  services to us. Dr. Wang currently receives an  annual
fixed fee of $100,000. In March 2016, we  granted him  a cash bonus in  the amount of $86,176. In
November 2016, we granted him an option to purchase 1,613,430 ordinary  shares that option had fair
value on  the grant date of $3,123,600. As  of  December  31,  2016, the  aggregate number  of  shares
subject to options held by Dr. Wang  was  7,112,597. In April 2017, we  granted him a cash bonus  in the
amount of $86,176.

Note Exchange

On February 2, 2011, we issued an 8% senior note for  an aggregate  principal  amount  of

$10 million to Merck Sharp & Dohme Research GmbH (‘‘MSD’’). On January  26, 2016, we entered
into a note amendment and exchange  agreement  with MSD.  On February 8,  2016, the entire
outstanding unpaid principal and interest  of the MSD note as of February 2, 2016  ($14,693,281) was
automatically exchanged for 7,942,314 of  our ordinary  shares  at $1.85 per share, the initial  offering
price per ordinary share calculated based on the initial public  offering  price per American Depositary
Share divided by 13, the ordinary share-to-ADS  ratio.

Warrant Exercises

On February 8, 2016, in connection with  the closing of our initial public offering, entities affiliated

with Baker Bros. Advisors LP exercised warrants  previously granted to them to purchase 2,592,593
ordinary shares at an exercise price of $0.675 per share.

exercised warrants previously granted  to  him to purchase 57,777 Series  A preferred  shares at an
exercise price of $0.675 per share, which shares  were converted into  57,777 ordinary  shares.

Employment Agreements

For more information regarding employment agreements with certain of our  executive officers,  see

‘‘Executive Compensation—Employment  Agreements  with Our Named  Executive Officers.’’

Indemnification Agreements

Cayman Islands law does not limit the extent to which  a company’s articles of  association may
provide indemnification of officers and  directors, except to the extent  any  such provision  may be held
by the Cayman Islands courts to be contrary  to  public  policy, such  as providing indemnification against
civil fraud or the consequences of committing  a crime. Our amended  and  restated memorandum and
articles of association provide that each officer or director shall be indemnified out  of assets of our

18

company against all actions, proceedings,  costs, charges, expenses, losses, damages or liabilities incurred
or sustained by such directors or officer, other  than by reason of such  person’s dishonesty, willful
default or fraud, in or about the conduct  of our company’s business or  affairs (including  as a result of
any mistake of judgment) or in the execution  or discharge of his duties, powers,  authorities  or
discretions, including without prejudice  to  the  generality of the  foregoing, any costs,  expenses, losses or
liabilities incurred by such director or officer in  defending (whether  successfully or  otherwise)  any civil
proceedings concerning our company  or  its affairs  in any  court whether in the Cayman Islands or
elsewhere.

In addition, we have entered into new agreements to indemnify our directors  and executive
officers. These agreements, among other  things, indemnify our directors  and  executive  officers against
certain liabilities and expenses incurred  by such persons in connection with claims  made by reason of
their being such a director or executive officer.

Agreements With Our Shareholders

In connection with our preferred share  financings, we entered into (1) an investors’ rights

agreement, (2) a right of first refusal and co-sale agreement  and  (3) a voting agreement, in  each case,
with the purchasers of our preferred  shares and certain holders of our ordinary  shares. The primary
rights under each of these terminated  upon the  closing  of our initial  public offering, other than  certain
registration rights for certain holders  of our ordinary  shares.

On November 16, 2016, we entered into an additional  registration rights agreement  with 667,  L.P.,
Baker Brothers Life Sciences, L.P. and  14159, L.P. (collectively, the ‘‘Baker Entities’’),  Hillhouse  BGN
Holdings Limited, Gaoling Fund, L.P.  and  YHG  Investment, L.P. (collectively, the  ‘‘Hillhouse Entities’’)
(each  an ‘‘Investor’’ and collectively,  the  ‘‘Investors’’), all  of  which are existing shareholders of our
Company. The Baker Entities are affiliated with  two of  the Company’s directors, Michael Goller  and
Ranjeev Krishana. The Hillhouse Entities are affiliated with  one  of  the Company’s directors,  Michael
Yi. The registration rights agreement provides  that,  subject to certain limitations, if at  any time and
from time to time, the Investors demand that  we register the  Company’s ordinary shares  and any other
securities of the Company held by the  Investors at the time any  such demand is made on a registration
statement on Form S-3 for resale under the  Securities Act, we would  be  obligated to effect such
registration. Our registration obligations under the registration rights  agreement will continue  in effect
for up to four years and include our obligation  to  facilitate certain underwritten  public offerings of our
ordinary shares or ADSs by the Investors in the future. The registration rights  agreement also requires
the Company to pay expenses relating to such registrations and indemnify the  Investors against  certain
liabilities.

COMPENSATION COMMITTEE INTERLOCKS AND  INSIDER PARTICIPATION

None of the members of our Compensation Committee  has at any time during 2016  been an

officer or employee of the Company. None of  our executive  officers currently serves, or in  the past
fiscal year has served, as a member of the board of directors or compensation  committee of  any entity
that has one or more executive officers serving on our  Board  of Directors or  Compensation
Committee.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING  COMPLIANCE

Section 16(a) of the Exchange Act requires our  officers and directors  and persons  who beneficially

own more than 10% of our ordinary shares (collectively,  ‘‘Reporting Persons’’) to file reports  of
beneficial ownership and changes in beneficial ownership  with  the SEC. Reporting Persons are required
by SEC regulations to furnish us with  copies  of all Section 16(a) forms  they file. Based  solely on our
review of such reports received or written representations from  certain Reporting  Persons  during  the
fiscal year ended December 31, 2016,  we  believe that all Reporting Persons complied with all
Section 16(a) reporting requirements.

19

Composition of Our Board of Directors

CORPORATE GOVERNANCE

Our Board of Directors currently consists of nine members,  all of whom were  elected  pursuant to
the board composition provisions of a voting agreement that terminated upon  the closing of our initial
public offering. Currently, we are not  subject to any  contractual obligations regarding the election of
our  directors. Our Nominating and Governance Committee and Board of Directors may therefore
consider a broad range of factors relating  to  the qualifications and background of  nominees, which may
include diversity and is not limited to  race,  gender or national origin.  We have no formal policy
regarding board diversity. Our Nominating and Governance Committee’s and  Board of Directors’
priority in selecting board members is identification of persons who will further the interests of our
Company through his or her established record of professional accomplishment, the ability  to
contribute positively to the collaborative culture among board members, knowledge of  our business,
understanding of the competitive landscape and professional and  personal experiences  and relevant
expertise. Our directors hold office until  their successors have been elected and  qualified or until the
earlier of their resignation or removal.

Our amended and restated articles of  association provide  that our directors may be removed by
the affirmative vote of the holders of at  least two-thirds  of the votes cast at a shareholder  meeting and
that any vacancy on our board of directors, including a  vacancy resulting  from an enlargement of our
Board of Directors, may be filled only  by  vote  of a majority of our directors  then in office.

In accordance with the terms of our amended and  restated memorandum and articles of
association, our Board of Directors is divided into three classes, Class I, Class II  and Class III, with
each  class serving staggered three-year terms.  Upon the expiration of the term  of a class of directors,
directors in that class will be eligible to be elected  for a  new three-year term at the  annual meeting of
shareholders in the year in which their  term expires.

(cid:129) Our Class I directors are Timothy Chen, John V. Oyler  and Ke  Tang;

(cid:129) Our Class II directors are Donald W.  Glazer, Michael Goller and Thomas Malley; and

(cid:129) Our Class III directors are Ranjeev  Krishana, Xiaodong Wang and Qingqing Yi.

 Ke Tang, who currently is a Class I  director, notified  us of his decision not to stand for re-election

to the Board of Directors when his current term expires at the Annual Meeting.

Our amended and restated memorandum and articles of association provide that the authorized
number of directors may be changed  only  by  ordinary  resolution of the  shareholders. Any additional
directorships resulting from an increase in the number of directors will be distributed among the three
classes so that, as nearly as possible,  each  class shall  consist  of one third of the Board of Directors.

Board and Committee Matters

Our Board of Directors has determined that all members of the Board of Directors,  except

John V. Oyler and Xiaodong Wang, are independent, as determined in accordance with the rules  of the
NASDAQ Stock Market. In making such independence  determination,  our Board of Directors
considered the relationships that each  such non-employee  director has with us and all other facts and
circumstances that the Board of Directors  deemed  relevant  in determining their independence,
including the beneficial ownership of  our  share capital by each non-employee director. In considering
the independence of the directors listed  above,  our Board of Directors considered the association of
our  directors with the holders of more  than 5% of our share capital. We expect  that  the composition
and functioning of our Board of Directors and each  of  our committees  will continue to comply with all
applicable requirements of the NASDAQ Stock Market  and the rules and regulations of  the SEC.
There are no family relationships among any of our directors or executive officers.

20

Corporate Governance

We  adopted a written code of business conduct and ethics that applies  to our directors, officers
and employees, including our principal executive  officer, principal financial officer, principal accounting
officer or controller, or persons performing similar  functions. A current copy of  the code is posted on
the Corporate Governance section of our website, which  is located at http://ir.beigene.com. If we make
any substantive amendments to, or grant any waivers from,  the  code of business conduct  and ethics for
any officer, we will disclose the nature  of  such  amendment  or waiver  on  our website or in a current
report on Form 8-K.

Board Meetings and Committees

Our Board of Directors held 11 meetings during 2016. The directors regularly hold executive

sessions at meetings of the Board of  Directors. During 2016,  each of the directors then in  office
attended at least 75% of the aggregate  of  all  meetings of the Board of Directors  and all meetings of
the committees of the Board of Directors  on which such director then served, except Timothy  Chen.
Now that we are a public company, continuing directors  and  nominees for election  as directors in a
given year are encouraged to attend the annual general meeting of shareholders, barring  significant
commitments or special circumstances.  This is  our first  annual general meeting  of  shareholders since
we became a public company.

Compensation Committee and Nominating and Corporate Governance Committee.

Nominating and Corporate Governance  Committee

Donald W. Glazer and Michael Goller currently serve on the  Nominating and Corporate

Governance Committee, which is chaired  by  Donald  W. Glazer. Our  Board of Directors has determined

22

that each member of the Nominating  and  Corporate  Governance Committee is ‘‘independent’’ as that
term is defined in the rules of the NASDAQ Stock Market. The Nominating  and Corporate
Governance committee’s responsibilities  include:

(cid:129) developing and recommending to the Board of  Directors criteria for board and  committee

membership;

nominees recommended by shareholders;

(cid:129) identifying individuals qualified to become  members of the Board of Directors;

(cid:129) recommending to the Board of Directors the  persons to be nominated  for election  as directors

and to each of the board’s committees;

(cid:129) developing and recommending to the Board of  Directors a set of corporate governance

guidelines; and

(cid:129) overseeing the evaluation of the Board of Directors and  management.

The Nominating and Corporate Governance committee held two meetings during  2016. The
Nominating and Corporate Governance  Committee operates pursuant to a written charter adopted by
the Board of Directors, which is available on our website  at http://ir.beigene.com.

Director Nominations

The Board of Directors will consider and approve from time to time the criteria  that  it deems
necessary or advisable for director candidates.  The Board of  Directors has  full authority to modify such
criteria as it deems necessary or advisable. The Board of Directors  has delegated to the Nominating
and Corporate Governance Committee the  responsibility for developing and  recommending  to  the
Board of Directors for its consideration  and approval  criteria for director candidates. The  Nominating
and Corporate Governance Committee has adopted  policies and procedures for director  candidates.
The Board of Directors may, however,  rescind  its delegation  and  assume  the  responsibilities it
previously delegated to the Nominating  and Corporate Governance Committee.

The Board of Directors has delegated to the  Nominating and Corporate Governance Committee

the responsibility to identify candidates for nomination to the Board  of Directors  (including candidates
to fill vacancies) and assessing their qualifications in light of the policies and  principles in our
Corporate Governance Guidelines and  the Committee’s charter. The Nominating and  Corporate
Governance Committee will recommend  director candidates  for  the Board of  Directors’ consideration
and review the candidates’ qualifications  with the  Board of Directors. The Board  of  Directors retains
the authority to nominate a candidate  for election by the securityholders as a director and  to  fill
vacancies. In identifying director candidates,  the Nominating and Corporate Governance Committee
may consider all facts and circumstances  it deems appropriate,  including, among other things, the skills
of the candidate, his or her depth and breadth of  business experience and other background
characteristics, his or her independence and the  needs of the Board of  Directors.

Our Nominating and Corporate Governance Committee  and Board of Directors may therefore
consider a broad range of factors relating  to  the qualifications and  background of  nominees, which may
include diversity and is not limited to  race,  gender or national origin.  We have no formal policy
regarding board diversity. Our Nominating and Corporate Governance Committee’s and  Board of
Directors’ priority in selecting board members is identification  of persons who  will further the interests
of our shareholders through his or her  established record  of professional accomplishment, the  ability to
contribute positively to the collaborative culture among board  members, knowledge of  our business,
understanding of the competitive landscape and professional and  personal experiences  and relevant
expertise.

Board Leadership Structure and Role  in Risk Oversight

Our Chief Executive Officer, John V. Oyler, is the Chairman of the Board of Directors.  The Board

of Directors believes that Mr. Oyler  is the  director best suited to identify strategic  opportunities and
focus of the Board of Directors due  to  his extensive understanding of our business as a  founder. The
Board of Directors also believes that  the combined role  of Chairman  and  Chief Executive Officer  can
promote the effective execution of strategic  initiatives and  facilitate the flow of information between
management and the Board of Directors.  We do not have  a  lead independent  director.

Our Board of Directors oversees the  management of risks inherent  in the operation of our

business and the implementation of our business strategies. Our Board  of  Directors performs this

24

oversight role by using several different  levels of review. In connection with its reviews of our
operations and corporate functions, our Board of Directors addresses the  primary  risks associated with
those operations and corporate functions.  In addition, our Board of Directors  reviews the risks
associated with our business strategies  periodically throughout the year.

Each  of our board committees also oversees the management of our risk  that falls within the
committee’s areas of responsibility. In performing this function,  each committee  has full access to
management, as well as the ability to  engage advisors. Our Chief Financial  Officer  reports to the Audit
Committee and is  responsible for identifying, evaluating and implementing risk management controls
and methodologies to address any identified risks. In connection  with its risk management role, our
Audit Committee meets privately with  representatives from our  independent  registered  public
accounting firm and our Chief Financial Officer.  The  Audit Committee  oversees the operation of our
risk management program, including  the  identification of the primary risks associated  with our business
and periodic updates to such risks, and  reports to our Board  of  Directors regarding  these  activities.

Audit Committee Report

The information contained in this report  shall not be deemed to be (1)  ‘‘soliciting material,’’
(2) ‘‘filed’’ with the SEC, (3) subject to Regulations 14A or 14C of the  Exchange Act, or  (4) subject  to
the liabilities of Section 18 of the Exchange Act. This report shall not  be  deemed incorporated by
reference into any of our other filings  under the Exchange Act or the Securities Act, except  to  the
extent that we specifically incorporate it by reference into such filing.

The Audit Committee operates under a written charter approved by the Board  of Directors, which

provides that its responsibilities include  the oversight  of the quality of our financial  reports and other
financial information and its compliance with  legal and regulatory requirements; the appointment,
compensation, and oversight of our independent registered public accounting  firm,  Ernst & Young Hua
Ming LLP, including reviewing their independence; reviewing and approving the planned scope of our
annual audit; reviewing and pre-approving  any  non-audit services that may  be  performed  by  Ernst &
Young Hua Ming LLP; the oversight of our  internal audit  function;  reviewing with management and
our  independent registered public accounting firm  the adequacy  of  internal financial controls; and
reviewing our critical accounting policies  and estimates and  the  application  of accounting principles
generally accepted in the United States of  America.

The Audit Committee oversees our financial reporting process on  behalf of the Board of Directors.

Management is responsible for our internal controls, financial  reporting  process,  and compliance with
laws and regulations and ethical business  standards. Ernst & Young Hua Ming LLP  is responsible for
performing an independent audit of  our consolidated financial statements  in accordance with  the
standards of the Public Company Accounting Oversight  Board (United  States). The Audit  Committee’s
main responsibility is to monitor and  oversee this  process.

The Audit Committee reviewed and  discussed with management our audited financial statements

for the fiscal year ended December 31, 2016.  The Audit Committee discussed with Ernst & Young Hua
Ming LLP the matters required to be discussed by  Public Company Accounting Oversight Board
(‘‘PCAOB’’) Auditing Standard No. 1301, Communications with Audit Committees, and SEC
Regulation S-X Rule 207, Communications with Audit Committees. The Audit Committee has received
the written disclosures and the letter from the independent registered public accounting firm required
by applicable requirements of the PCAOB regarding the independent registered  public accounting
firm’s communications with the Audit  Committee concerning independence,  and has  discussed with the
independent registered public accounting  firm the independent  registered  public  accounting firm’s
independence.

25

The Audit Committee considered any fees paid to Ernst & Young Hua Ming  LLP for the

provision  of non-audit related services  and does  not  believe that these fees compromise Ernst  & Young
Hua Ming LLP’s independence in performing the audit.

Based on the review and discussions referred to above, the Audit  Committee recommended  to  the

Board of Directors that such audited  financial statements be  included in our Annual Report on
Form 10-K for the year ended December  31, 2016, for filing with  the SEC.

EXECUTIVE COMPENSATION

Overview

Our compensation programs are designed to:

(cid:129) attract and retain individuals with superior ability, technical, and managerial  experience;

(cid:129) align executive officers’ incentives with  our corporate strategies, business objectives and the

long-term interests of our shareholders; and

(cid:129) increase the incentive to achieve key strategic performance measures by linking incentive  award
opportunities to the achievement of performance  objectives and by providing a portion of total
compensation for executive officers in the form  of  ownership  in the Company.

Our Compensation Committee is primarily  responsible for developing and implementing our

compensation policies and establishing and approving the  compensation  for all of our executive officers;
with respect to the Chief Executive Officer and Chief Financial Officer, the Compensation Committee
reviews and makes recommendations  to  the full Board of Directors for  approval. The Compensation
Committee oversees our compensation and  benefit plans  and policies, administers  our equity incentive
plans, reviews and approves annually all compensation decisions relating to our executive  officers, and
makes recommendations to the full Board  of Directors on compensation for the Chief Executive
Officer and Chief Financial Officer.  The  Compensation Committee considers recommendations  from
our  Chief Executive Officer regarding  the compensation of our executive officers other than the Chief
Executive Officer and Chief Financial  Officer. Our Compensation  Committee has the authority under
its  charter to engage the services of a  consulting firm or  other  outside advisor to assist it in designing
our  compensation programs and in making compensation decisions.

In 2016, the Compensation Committee retained Willis Towers Watson to assist in  an evaluation of
our  compensation philosophy, validation  of our compensation peer group, develop competitive market
data to  benchmark the compensation  for  our  named  executive officers and advise on matters related to
our  compensation structure and programs  generally. The compensation consultant also consults with
the Compensation Committee about  non-employee director  compensation.  Based on consideration of
the factors set forth in the rules of the  SEC and  NASDAQ, the Compensation Committee has
determined that their relationship with  Willis Towers  Watson  and  the work performed by Willis  Towers
Watson on behalf of the Compensation Committees has not raised any conflict of interest.

Executive Compensation Components

Our executive compensation consists  of base salary,  performance-based cash compensation,

long-term incentive compensation in the form  of share  options,  restricted shares and broad-based
benefits programs. The Compensation Committee  considers a number of factors in setting
compensation for our executive officers, including company performance, as well  as the executive’s
performance, experience, responsibilities  and the compensation of executive officers in  similar positions
at comparable companies.

Base Salary

Base salary is intended to provide compensation  for day-to-day performance. The Compensation

Committee believes that a competitive  base salary is a  necessary element of any compensation program
that is designed to attract and retain  talented  and  experienced executives. Base salaries for our named
executive officers are intended to be competitive with those received by  other  individuals in similar
positions at the companies with which  we compete for  talent. Base salaries are originally established at
the time the executive is hired based on individual experience, skills and expected contributions, our
understanding of what executives in similar positions at  peer companies were paid, and also

27

negotiations during the hiring process.  The base salaries of our named executive  officers are reviewed
annually and may be adjusted to reflect  market  conditions, the financial position of the Company, and
our  executives’ performance as well as any change in the scope of an  officer’s responsibilities. As of
December 31, 2016, the base salaries  of our named  executive officers were  as described  in ‘‘—Summary
Compensation Table—2016’’ below.

Performance-Based Cash Bonus

Our Compensation Committee has the authority to award  annual performance-based  cash bonuses

to our executive officers and make recommendations to the  full Board  of  Directors for approval of
performance-based cash bonuses for the  Chief Executive Officer and Chief Financial Officer. Unless
otherwise provided by the provisions of  his  or her employment agreement,  the target annual  cash bonus
opportunities for our named executive officers are  expressed as  a  percentage  of  base  salary and
generally established by our Compensation Committee based on competitive market data and
recommendations by the Chief Executive  Officer (other than in connection  with his  own
compensation). In 2017, the Board of Directors and Compensation Committee approved performance-
based cash bonuses for our named executive officers as described  in ‘‘Summary Compensation  Table—
2016’’ below. These payments were awarded in  recognition of our  named executive officer’s
performance in achieving corporate,  clinical, and operational milestones in 2016.

Equity Incentive Compensation

Equity incentive grants to our named executive officers are made at the discretion of the
Compensation Committee under the  terms of our equity incentive plans  except  for equity  incentive
grants for the Chief Executive Officer  and  Chief  Financial Officer, which are approved by the full
Board of Directors. We believe that equity  incentives subject to vesting  over time  or upon  achievement
of performance objectives can be an effective vehicle for the long-term  element of compensation, as
these awards  align individual and team performance with the achievement  of our  strategic and financial
goals over time and with shareholders’ interests. In 2016, the Compensation  Committee made share
option and restricted share grants to our named executive officers  as specified in  the ‘‘Outstanding
Equity Awards at Fiscal Year-End Table—2016’’ below. All  options to purchase shares  granted to
executives have exercise prices equal  to  at least  the fair market  value of our ordinary shares  on the
date  of  grant, and therefore reward executive officers only if  the share price increases from  the date of
grant.

Employee Benefits

In addition to the primary elements of  compensation  described above, the named executive officers

also participate in the same broad-based employee benefits programs available to all of our other
employees (which may vary based on the location of employment), including health insurance, pension
benefits, employee housing fund, welfare benefits,  life and  disability  insurance, dental insurance, and
retirement plan. We do not provide special  benefits to our named executive officers except as otherwise
described in this Proxy Statement.

Summary Compensation Table—2016

The following table presents information regarding  the total compensation awarded to, earned by,
and paid during the fiscal years ended  December 31,  2016 and  2015 to our Chief Executive Officer and
the two most highly-compensated executive officers (other  than the Chief Executive  Officer) who  were
serving as executive officers at the end of  the year ended  December  31, 2016. These individuals are  our
named executive officers for 2016.

Howard Liang, Ph.D. On July 13, 2015, we entered into an employment agreement with  Dr. Liang
for the position of Chief Financial and  Chief Strategy Officer. Dr.  Liang currently receives  a base salary
of $350,000, which is subject to review and adjustment in accordance  with company  policy. Dr.  Liang is
eligible for an annual merit bonus of up  to $105,000, based on  performance as determined by our
Compensation Committee. Dr. Liang  was also granted an  option to purchase up to 4,900,000 ordinary
shares, which vests over four years. Dr.  Liang is eligible to participate  in our employee benefit  plans
generally available to our employees,  subject to the  terms of those  plans.  Dr. Liang’s employment has
no specified term, but can be terminated at  will by either party. Dr. Liang’s employment may be
terminated by us without ‘‘cause’’ (as defined in his employment  agreement), and if so he  would receive
his base salary and health and dental insurance payments during a nine-month severance period and
other benefits including acceleration  of the  vesting  schedule  of  his initial  option grant  by  six months,
unless Dr. Liang breaches his confidentiality obligations.  Dr. Liang may terminate his employment with
‘‘good reason’’ (as defined in his employment agreement)  upon 30  days’ written notice  received  within
60 days of the occurrence of the event. If we  do not  cure the  action identified in  Dr. Liang’s notice, he
is entitled to the same benefits as if  we terminated  his employment  without  cause, subject to his
execution of a release of claims and unless he breaches  his confidentiality obligations. We may  also
terminate Dr. Liang’s employment for cause, in certain  cases upon  30 days’ written notice, and
Dr. Liang may also terminate his employment without good reason upon 90 days’ written notice,  in
either case, in which he would then only  be entitled  to  receive certain accrued  obligations.

Ji Li, Ph.D. On April 28, 2016, we entered into an employment agreement with Dr. Li for the

position of Executive Vice President and Global Head of Business  Development. Dr. Li currently
receives a base salary of $350,000, which is subject  to  review and adjustment in accordance  with

30

company policy. Dr. Li is eligible for  an annual merit bonus of up to $140,000, based  on performance
as determined by our Compensation Committee. Dr.  Li was granted  an  option to purchase up to
2,376,000 ordinary shares, which vests  over four years. Dr. Li was also granted  475,000 restricted shares,
which  vest in equal installments annually  over a four-year period. Dr. Li is eligible to participate in our
employee benefit plans generally available to our employees, subject to the terms of those  plans.
Dr. Li’s employment has no specified term, but can be terminated  at  will by either  party. Dr. Li’s
employment may be terminated by us  without ‘‘cause’’ (as defined  in his employment  agreement),  and
if so he would receive his base salary and health and dental insurance payments  during  a nine-month
severance period and other benefits including acceleration of the vesting schedules of his initial option
grant and restricted share award by 12 months (or 18 months if such termination occurs  within
12 months following a ‘‘change in control’’  (as defined in his employment agreement)),  unless Dr.  Li
breaches his confidentiality obligations.  Dr. Li may terminate his employment with ‘‘good  reason’’ (as
defined in his employment agreement) upon 30 days’ written  notice received within 60 days  of the
occurrence of the event. If we do not  cure the action  identified in Dr.  Li’s notice, he is entitled to the
same benefits as if we terminated his employment without cause, subject to his execution of a release
of claims and unless he breaches his  confidentiality  obligations. We may also terminate Dr.  Li’s
employment for cause, in certain cases upon 30 days’ written  notice, and Dr.  Li may also  terminate  his
employment without good reason upon  90  days’ written notice, in either case, in which he  would then
only be entitled to receive certain accrued obligations.

Compensation Risk Assessment

We  believe that although a portion of the compensation provided  to  our executive  officers and

other employees is performance-based,  our executive compensation program does  not  encourage
excessive or unnecessary risk taking. This is primarily due to  the fact that our compensation programs
are designed to encourage our executive  officers and  other employees  to  remain focused on both
short-term and long-term strategic goals, in particular in  connection with  our  pay-for-performance
compensation philosophy. As a result, we  do not believe that our  compensation  programs  are
reasonably likely to have a material adverse effect  on us.

Benefit Plans

Our full-time employees in the People’s Republic of  China  (‘‘PRC’’),  including some of our named

executive officers, participate in a government mandated defined contribution  plan, pursuant to which
pension benefits, medical care, employee  housing fund  and other welfare benefits are  provided to
employees. Chinese labor regulations require that our PRC  subsidiaries make contributions to the
government for these benefits based on  percentages of the employees’ salaries.

Our U.S. subsidiary maintains a 401(k)  retirement plan for  all of its full-time employees in the

United States, including some of our named executive  officers, with  an opportunity to save  for
retirement on a tax-advantaged basis. Pursuant  to  the 401(k) plan, participants will be able  to  elect  to
defer their current compensation by up  to  the statutorily prescribed annual limit, with additional  salary
deferral amounts available to participants beginning in  the year they become 50  years  of  age. Our
U.S. subsidiary matches 50% of employee contributions,  limited to the first 6%  of  compensation, those
employer-matching contributions to vest  50% after one year  and be fully  vested  after the second
anniversary of the employment date.

Rule 10b5-1 Plans

Our policy governing transactions in  our securities by directors, officers and employees permits our

officers, directors and certain other persons  to  enter into trading plans complying with  Rule 10b5-1
under the Exchange Act. Under these  trading  plans, the  individual relinquishes  control over the
transactions once the trading plan is put  into place. Accordingly, sales under  these  plans may  occur at
any time, including possibly before, simultaneously with,  or immediately after  significant events
involving our Company.

DIRECTOR COMPENSATION

Our Board of Directors has adopted an independent director compensation  policy that is part  of a

total compensation package that is designed to enable us to attract  and retain, on a long-term  basis,
high caliber independent directors. Under  the policy, all independent directors  are paid cash
compensation as set forth below:

Under our independent director compensation policy,  each newly appointed  or elected
independent director is eligible to receive  a  one-time  grant of  a  non-qualified option  to  purchase
260,000 ordinary shares. The date of  grant is the  date he or she first becomes an  independent director.
These options become exercisable in three  equal annual  installments during the three  years  following
the grant date, subject to the director’s continued service on the Board of Directors.

In addition, on the date of each annual general meeting of shareholders,  each continuing

independent director who has served  as a  director for the  previous six months is  eligible to receive a
non-qualified option to purchase 169,988 ordinary shares. The annual grants become  exercisable  on the
earlier of the one-year anniversary of  the date of grant or  the  date of our next annual general meeting
of shareholders, subject to the director’s  continued service  on the  Board.

The foregoing options will have an exercise price equal  to  one thirteenth of the fair market  value

of an ADS on the NASDAQ Stock Market on  the date of grant and  be  subject to the terms of the
2016 Plan.

We  also reimburse all reasonable out-of-pocket expenses incurred by independent directors in

attending board and committee meetings.

The following table sets forth a summary of the compensation we paid to our directors during
2016. Other than as set forth in the table,  we did not  pay any compensation,  make  any equity  awards
or non-equity awards to, or pay any other  compensation to, any  members of our Board  of  Directors in
2016. Mr. Oyler, our Founder, Chief  Executive  Officer  and Chairman, receives no  compensation for  his
service as a director and, consequently,  is  not  included in  this table.  Dr. Xiaodong Wang, Chair of our
Scientific Advisory Board, also receives no compensation for  his service as  a director. The

35

compensation received by Mr. Oyler as  an employee during 2016 is presented  in ‘‘Summary

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, 2016. The amounts above reflect our
aggregate accounting expense for these  options and do not necessarily  correspond to the actual
value that will be recognized by the directors.

(4) Mr.  Yi voluntarily waived the receipt  of director compensation in 2016.
