Dear Halozyme Shareholders,

Our  company  and  shareholders  have  many  reasons  to  be  excited  about  our  2014 

accomplishments.  Significant  progress  was  made  towards  realizing  our  long‑term 

vision  of  developing  breakthrough  cancer  medicines  and  building  a  leading 

biotechnology  company.  During  the  course  of  the  year,  after  completing  a  full 

assessment of our assets, R&D programs and core capabilities, we charted a course 

to focus our efforts on our investigational new drug PEGPH20 (PEGylated form of 

rHuPH20) and the ENHANZE™ technology. We believe that these two assets have the 

highest potential to meaningfully impact patients’ lives and create value.

PEGPH20
In  2014,  we  made  strong  progress  in  our  goal  to  explore  the  potential  of  PEGPH20  in  a 
full  range  of  solid  tumors  where  accumulation  of  high  levels  of  hyaluronan  (HA)  has  been 
associated with lower survival rates. After the brief clinical hold in the spring, we advanced our 
Phase 2 study in newly diagnosed patients with metastatic pancreatic cancer and initiated a 
new study in patients with non-small cell lung cancer who had failed their initial treatments. 
The  significant  unmet  need  that  exists  in  treating  pancreatic  cancer  was  recognized  by  the 
U.S. Food and Drug Administration (FDA) granting Fast Track and Orphan Drug designation. 
Additionally, the European Commission, acting on the recommendation from the Committee 
for Orphan Medicinal Products of the European Medicines Agency, designated PEGPH20 an 
orphan medicinal product for the treatment of pancreatic cancer.

In January 2015, we presented encouraging early efficacy and safety data based on an interim 
analysis of our ongoing Phase 2 trial. Study 202 is evaluating PEGPH20 in combination with 
gemcitabine  and  ABRAXANE®  (nab-paclitaxel)  compared  to  gemcitabine  and  ABRAXANE® 
(nab-paclitaxel) alone in patients with previously untreated metastatic pancreatic cancer. The 
interim analysis of Study 202 has provided insights into the potential clinical benefit and potential 
risks  of  PEGPH20  in  patients  with  metastatic  pancreatic  cancer  whose  tumors  accumulate 
high levels of HA. During the course of 2015, we anticipate expanding and accelerating our 
PEGPH20 clinical development efforts with goals of completing Study 202 enrollment, gaining 
feedback from regulatory authorities on our plans to initiate a registration trial for PEGPH20 
in  pancreatic  cancer  patients  whose  tumors  accumulate  high  levels  of  HA  and  completing 
enrollment in the Phase 1b portion of the non-small cell lung cancer trial, PRIMAL. Plans are 
also underway to start a new study evaluating PEGPH20 with an immuno-oncology agent. 

ENHANZE
The ENHANZE™ platform is based on our patented rHuPH20 enzyme, which, when administered 
in  combination  with  other  medicines  or  just  before  the  administration  of  high  volumes  of 
immune globulin, can allow for subcutaneous administration where previously this was not 
possible.  I  am  excited  to  report  multiple  value-creating  events  in  2014  beginning  with  the 
encouraging  market  reception  in  Europe  to  Roche’s  Herceptin®  SC  (trastuzumab)  and  the 
June launch of Roche’s MabThera® SC (rituximab). The uptake of Herceptin SC (trastuzumab), 
continues to impress, with Roche reporting increasing share in a number of launch markets with 
many still at an early stage and new markets launching each month. In some launch markets 
where  the  healthcare  systems  have  reviewed  and  recognized  the  value  of  subcutaneous 
administration, up to 50% of Herceptin intravenous use is now administered subcutaneously.

In  September  2014,  the  FDA  approved  Baxter’s  HYQVIA  [Immune  Globulin  Infusion  10% 
(Human)  with  Recombinant  Human  Hyaluronidase].  This  represents  the  first  U.S.  approval 
of  a  product  utilizing  ENHANZE,  and  for  patients,  this  approval  provided  a  new  treatment 
option  for  adult  patients  with  Primary  Immune  Deficiency.  Instead  of  requiring  often  12  to 
20  subcutaneous  injections  to  receive  the  full  dose  of  immune  globulin,  patients  receiving 
HYQVIA generally require just the one monthly injection.

Less than 100 days after receiving FDA approval for HYQVIA, our ENHANZE platform gained 
further  validation  and  expansion  in  the  fourth  quarter  with  our  announcement  of  a  global 
collaboration with Janssen to develop and commercialize subcutaneous products utilizing this 
technology. Under the terms of the agreement, we granted Janssen an exclusive worldwide 
license  to  develop  and  commercialize  products  for  up  to  five  targets  combining  ENHANZE 
with  Janssen’s  proprietary  compounds.  Daratumumab,  a  monoclonal  antibody  that  targets 
CD38, is the first of five proprietary compounds at Janssen to be combined with ENHANZE. 
This agreement has the potential to lead to the development of a subcutaneous formulation 
of daratumumab. Daratumumab is being developed under a collaboration between Janssen 
and Genmab A/S since August 2012 when Genmab granted Janssen an exclusive worldwide 
license to develop, manufacture, and commercialize daratumumab. Daratumumab, a human 
monoclonal antibody that targets CD38 on the surface of multiple myeloma cells, is in clinical 
development as a single agent and in combination with standard of care therapies in several 
settings  of  multiple  myeloma.  Daratumumab  may  also  have  potential  in  other  hematologic 
malignancies  in  which  CD38  is  expressed,  including  non-Hodgkins  lymphoma  and  various 
leukemias.  The  agreement  provides  for  milestone  payments  totaling  up  to  $566  million,  in 
addition  to  royalty  payments  based  on  net  sales  of  products  using  ENHANZE  technology. 
Janssen joins Roche, Pfizer and Baxter as a partner in our ENHANZE franchise and it is our goal 
to increase the number of ENHANZE partnerships, as well as support our partners’ efforts in 
moving new programs into clinical development. Interest from marquee pharmaceutical and 
biotechnology  companies  to  license  our  technology  remains  high  and  we  look  forward  to 
providing you with an update on these initiatives in the future.

Halozyme ended 2014 with approximately $136 million in cash and we do not anticipate the 
need for dilutive financing to fund operations this year. In 2015, we expect our revenues to 
increase over the prior year which, in part, will be driven by the increase in royalty revenues we 
receive from Roche and Baxter.

By all measures 2014 was one of the strongest performance years in Halozyme history. Patients 
are at the center of all that we do and the recognition that patients are waiting is our motivation 
to continue to innovate and seek to excel. Our progress would not be possible without the 
past  or  ongoing  efforts  of  members  of  the  Halozyme  team,  our  investigators,  patients  and 
their families. We are very enthusiastic about our ability to make a difference for patients and 
their families, and in so doing, create value for our shareholders. Thank you for your support.

Sincerely,

Helen Torley, M.B. Ch. B., M.R.C.P.

Item 1.   Business 

Overview  

PART I  

Halozyme is seeking to translate our unique knowledge of the tumor microenvironment to create novel therapies that can improve cancer 
survival. Our research focuses on human enzymes that alter the extracellular matrix and tumor microenvironment. The extracellular matrix is a 
complex matrix of proteins and carbohydrates surrounding the cell that provides structural support in tissues and orchestrates many important 
biological  activities,  including  cell  migration,  signaling  and  survival.  Over  many  years,  we  have  developed  unique  technology  and  scientific 
expertise enabling us to pursue this target-rich environment for the development of therapies.  

Our  proprietary  enzymes  can  be  used  to  facilitate  the  delivery  of  injected  drugs  and  fluids,  potentially  enhancing  the  efficacy  and  the 
convenience of other drugs or can be used to alter abnormal tissue structures for clinical benefit. We have chosen to exploit our technology and 
expertise  in  a  balanced  way  to  modulate  both  risk  and  spend  by:  (1)  developing  our  own  proprietary  products  in  therapeutic  areas  with 
significant unmet medical needs, with a focus on oncology, and (2) licensing our technology to biopharmaceutical companies to collaboratively 
develop products which combine our technology with the collaborators' proprietary compounds.  

The  majority  of  our  approved  product  and  product  candidates  are  based  on  rHuPH20,  our  patented  recombinant  human  hyaluronidase 
enzyme. rHuPH20 temporarily breaks down hyaluronic acid (HA), a naturally occurring substance that is a major component of the extracellular 
matrix in tissues throughout the body such as skin and cartilage. We believe this temporary degradation creates an opportunistic window for the 
improved subcutaneous delivery of injectable biologics, such as monoclonal antibodies and other large therapeutic molecules, as well as small 
molecules  and  fluids.  We  refer  to  the  application  of  rHuPH20  to  facilitate  the  delivery  of  other  drugs  or  fluids  as  Enhanze  ™  technology. 
rHuPH20 is also the active ingredient in our first commercially approved product, Hylenex ® recombinant.  

1  

 
 
 
 
 
Our proprietary development pipeline consists primarily of clinical stage product candidates in oncology and diabetes. Our lead oncology 
program is PEGPH20 (PEGylated recombinant human hyaluronidase), a new molecular entity, under development for the systemic treatment of 
tumors that accumulate HA. When HA accumulates in a tumor, it can cause higher pressure in the tumor, reducing blood flow into the tumor and 
with that, reduced access of cancer therapies to the tumor. PEGPH20 works by temporarily degrading HA surrounding some cancer cells and 
results in reduced pressure and increased blood flow to the cancer with increased amounts of anticancer treatments administered concomitantly 
gaining access to the tumor. We are currently in Phase 2 clinical testing for PEGPH20 in metastatic pancreatic cancer (Study 109-202), and we 
have recently initiated a clinical trial in non-small cell lung cancer (Study 107-201). We have also been investigating Hylenex recombinant for 
use as pre-treatment in patients with Type 1 diabetes using pumps.  

Our  recent  receipt  of  Fast  Track  and  Orphan  Drug  designations  for  PEGPH20,  new  pre-clinical  data  further  supporting  the  pan-tumor 
potential  for  PEGPH20  and  investigator  interest  in  both  pancreatic  and  lung  cancer  trials  have  confirmed  PEGPH20  as  our  priority  product 
candidate for investment. As a result of ongoing evaluations to confirm and focus on the highest value opportunities, we have made the decision 
to seek collaborations with third parties or explore other strategic alternatives in order to exploit our diabetes and dermatology programs.  

Regarding  Enhanze,  we  currently  have  collaborations  with  F.  Hoffmann-La  Roche,  Ltd.  and  Hoffmann-La  Roche,  Inc.  (Roche),  Baxter 
Healthcare  Corporation  (Baxter),  Pfizer  Inc.  (Pfizer)  and  Janssen  Biotech,  Inc.  (Janssen),  with  one  product  approved  in  the  U.S.  and  three 
products approved for marketing in Europe from which we are receiving royalties and several others at various stages of development.  

Future revenues from the sales and/or royalties of our product candidates which have not been approved or have recently been approved 
will depend on the ability of Halozyme and our collaborators to develop, manufacture, secure regulatory approvals for and commercialize the 
product  candidates.  We  have  incurred  net  operating  losses  each  year  since  inception,  with  an  accumulated  deficit  of  approximately  $450.4 
million as of December 31, 2014 .  

Our  principal  offices  and  research  facilities  are  located  at  11388 Sorrento  Valley  Road,  San Diego,  California  92121.  Our  telephone 
number is (858) 794-8889 and our e-mail address is info@halozyme.com . Our website address is www.halozyme.com . Information found on, or

that we filed with the SEC are available on our website at www.halozyme.com , free of charge, as soon as reasonably practicable after we have 
electronically filed such material with, or furnished them to, the SEC, including our annual reports on Form 10-K, quarterly reports on Form 10-
Q, current reports on Form 8-K and any amendments to those reports. Further copies of these reports are located at the SEC's Public Reference 
Room at 100 F Street, N.W., Washington, D.C. 20549, and online at http://www.sec.gov .  

Technology  

The  majority  of  our  approved  product  and  product  candidates  are  based  on  rHuPH20,  a  patented  recombinant  human  hyaluronidase 
enzyme. rHuPH20 temporarily breaks down HA - a naturally occurring substance that is a major component of the extracellular matrix in tissues 
throughout  the  body  such  as  skin  and  cartilage.  We  believe  this  temporary  degradation  creates  an  opportunistic  window  for  the  improved 
subcutaneous delivery of injectable biologics, such as monoclonal antibodies and other large therapeutic molecules, as well as small molecules 
and  fluids.  The  HA  reconstitutes  its  normal  density  within  several  days  and,  therefore,  we  anticipate  that  any  effect  of  rHuPH20  on  the 
architecture  of  the  subcutaneous  space  is  temporary.  rHuPH20  can  thus  be  applied  as  a  drug  delivery  platform  to  increase  dispersion  and 
absorption of other injected drugs and fluids that are injected under the skin or in the muscle thereby enhancing efficacy or convenience. For 
example, rHuPH20 can be used to convert drugs that must be delivered intravenously into subcutaneous injections or to reduce the number of 
subcutaneous injections needed for effective therapy. We refer to the application of rHuPH20 to facilitate the delivery of other drugs or fluids as 
Enhanze technology. rHuPH20 is also the active ingredient in our first commercially approved product, Hylenex recombinant.  

Additionally,  we  are  expanding  our  scientific  work  to  develop  other  enzymes  and  agents  that  target  the  extracellular  matrix's  unique 
aspects,  giving  rise  to  potentially  new  molecular  entities  with  a  particular  focus  on  oncology.  For  example,  we  are  developing  a  PEGylated 
version of the rHuPH20 enzyme (PEGPH20), that lasts for an extended period in the bloodstream, and may therefore better target solid tumors 
that  accumulate  HA  by  degrading  the  surrounding  HA  and  reducing  the  interstitial  fluid  pressure  within  malignant  tumors  to  allow  better 
penetration by co-administered agents.

Strategy  

During the fourth quarter of 2014, we affirmed our strategy of focusing on developing our PEGPH20 product candidate for oncology as 
well  as  entering  into  collaborations  for  Enhanze  Technology.  This  business  model  allows  for  growth  in  which  revenue  garnered  from 
collaboration products helps fund our investment in PEGPH20 clinical development, with the goal of a future product approval that will support 
sustained growth.  

Key aspects of our corporate strategy include the following:  

•   Focus  on  developing  PEGPH20  our  investigational  new  drug  candidate  in  multiple  different  tumors  that  accumulate  high 
levels of HA. PEGPH20 is in phase 2 development in metastatic pancreatic cancer and in phase 1 development in Non-Small 
Cell Lung Cancer. Over time it is our goal to study additional types of cancer and to advance this program toward regulatory 
approval and commercial launch.  

•   Focus on Enhanze collaborations. We currently have four collaborations with three current product approvals and additional 
product  candidates  being  evaluated  for  development.  We  intend  to  work  with  our  existing  collaborators  to  expand  our 
collaborations  to  add  new  targets  and  product  candidates  under  the  terms  of  the  operative  agreements.  In  addition,  we  will 
continue our efforts to enter into new collaborations to further exploit our technology and derive value therefrom.  

Product and Product Candidates  

We have one marketed proprietary product and multiple proprietary product candidates targeting several indications in various stages of 
development. The following table summarizes our proprietary product and product candidates as well as products and product candidates under

Hylenex  recombinant  is  a  formulation  of  rHuPH20  that  has  received  FDA  approval  to  facilitate  subcutaneous  fluid  administration  for 
achieving hydration, to increase the dispersion and absorption of other injected drugs and, in subcutaneous urography, to improve resorption of 
radiopaque agents. Hylenex recombinant is currently the number one prescribed branded hyaluronidase.  

PEGPH20  

We  are  developing  PEGPH20  as  a  candidate  for  the  systemic  treatment  of  tumors  that  accumulate  HA  in  combination  with  currently 
approved  cancer  therapies.  'PEG'  refers  to  the  attachment  of  polyethylene  glycol  to  rHuPH20,  thereby  creating  PEGPH20.  One  of  the  novel 
properties  of  PEGPH20 is that  it lasts  for an  extended  duration  in the bloodstream  (one to two  days)  and, therefore, can be used  to  maintain 
therapeutic effect to treat systemic disease.  

Cancer malignancies, including pancreatic, lung, breast, colon and prostate cancers, often accumulate high levels of HA and therefore we 
believe that PEGPH20 has the potential to help patients with these types of cancer when used with currently approved cancer therapies. Among 
solid tumors, pancreatic ductal adenocarcinoma has been reported to be associated with the highest frequency of HA accumulation.  

Over 100,000 patients in the U.S. and EU are diagnosed with pancreatic cancer annually and are frequently diagnosed in late stage of the 
disease. The pathologic accumulation of HA, along with other matrix components, creates a unique microenvironment for the growth of tumor 
cells compared to normal cells. We believe that depleting the HA component of the tumor microenvironment with PEGPH20 remodels the tumor 
microenvironment, resulting in tumor growth inhibition. Removal of HA from the tumor microenvironment results in expansion of previously 
constricted blood vessels to allow increased blood flow, increasing the access of activated immune cells and factors in the blood into the tumor 
micro  environment.  If  PEGPH20  is  administered  in  conjunction  with  other  anti-cancer  therapies,  the  increase  in  blood  flow  may  allow  anti-
cancer  therapies  to  have  greater  access  to  the  tumor,  which  may  enhance  the  treatment  effect  of  therapeutic  modalities  like  chemotherapies, 
monoclonal antibodies and other agents.  

Study Halo 109-201 :  

In  January  2015,  we  presented  the  final  results  from  Study  109-201,  a  multi-center,  international  open  label  dose  escalation  Phase  1b 
clinical study of PEGPH20 in combination with gemcitabine for the treatment of patients with stage IV metastatic pancreatic cancer at the 2015 
Gastrointestinal  Cancers  Symposium  (also  known  as  ASCO-GI  meeting).  This  study  enrolled  28  patients  with  previously  untreated  stage  IV 
pancreatic  ductal  adenocarcinoma.  Patients  were  treated  with  one  of  three  doses  of  PEGPH20  (1.0,  1.6  and  3.0  µg/kg  twice  weekly  for  four 
weeks, then weekly thereafter) in combination with gemcitabine 1000 mg/m2 administered intravenously. In this study, the confirmed overall 
response rate (complete response + partial response confirmed on a second scan as assessed by an independent radiology review) was 29 percent 
(7 of 24 patients) for those treated at therapeutic dose levels of PEGPH20 (1.6 and 3.0 µg/kg). Median progression free survival (PFS) was 154 
days (95% CI, 50-166) in the efficacy-evaluable population (n = 24). Among efficacy-evaluable patients with baseline tumor HA staining (n = 
17), the median PFS in patients with high baseline tumor HA staining (6/17 patients) was substantially longer, 219 days, than in the patients with 
low  baseline  tumor  HA  staining  (11/17  patients),  108  days.  Median  overall  survival  (OS)  was  200  days  (95%  CI,  123-370)  in  the  efficacy-
evaluable population (n = 24). Among efficacy-evaluable patients with baseline tumor HA staining (n = 17), the median OS in patients with high 
baseline tumor HA staining (6/17 patients) was substantially longer, 395 days, than in the patients with low baseline tumor HA staining (11/17 
patients),  174  days.  The  most  common  treatment-emergent  adverse  events  (occurring  in  ≥  15%  of  patients)  were  peripheral  edema,  muscle 
spasms,  thrombocytopenia,  fatigue,  myalgia,  anemia,  and  nausea.  Thromboembolic  events  were  reported  in  8  patients  (28.6%)  and 
musculoskeletal events were reported in 21 patients (75%) which were generally grade 1/2 in severity.

Study Halo 109-202 :  

In the second quarter of 2013, we initiated Study 109-202, a Phase 2 multicenter randomized clinical trial evaluating PEGPH20 as a first-
line therapy for patients with stage IV metastatic pancreatic cancer. The study was designed to enroll patients who would receive gemcitabine 
and nab-paclitaxel (ABRAXANE ® ) either with or without PEGPH20. The primary endpoint is to measure the improvement in progression-free 
survival  in  patients  receiving  PEGPH20  plus  gemcitabine  and  nab-paclitaxel  compared  to  those  who  are  receiving  gemcitabine  and  nab-
paclitaxel alone. In April 2014, after 146 patients had been enrolled, the trial was put on clinical hold by Halozyme and the FDA to assess a 
question  raised  by  the  Data  Monitoring  Committee  regarding  a  possible  difference  in  the  thromboembolic  event  rate  between  the  group  of 
patients  treated  with  PEGPH20,  nab-paclitaxel  and  gemcitabine  (PAG  arm)  versus  the  group  of  patients  treated  with  nab-paclitaxel  and 
gemcitabine without PEGPH20 (AG arm). This portion of the study and patients in this portion are now referred to as Stage 1. It should be noted 
that at the time of the clinical hold all patients remaining in the study continued on gemcitabine and nab-paclitaxel. In July 2014, the Study 109-
202  was  reinitiated  (Stage  2)  under  a  revised  protocol,  which  excludes  patients  that  are  expected  to  be  at  a  greater  risk  for  thromboembolic 
events,  provides  for  prophylaxis  of  all  patients  in  both  arms  of  the  study  with  low  molecular  weight  heparin,  and  adds  evaluation  of  the 
thromboembolic event rate in Stage 2 patients compared with Stage 1 as a co-primary end point. Stage 2 of Study 109-202 is designed to enroll 
an additional 114 patients, to add to the 146 patients already accrued in the clinical trial, with a 2:1 randomization for PAG compared to AG.  

In  January  2015,  we  disclosed  initial  efficacy  and  safety  data  from  an  interim  assessment  of  Stage  1  of  Study  109-202.  In  the  safety 
evaluable population, i.e. patients who had received at least one dose of study drugs in test or comparator arm, of 135 patients (74 in PAG arm, 
61 in AG arm), the RECIST 1.1 Objective Response Rate, based on patient data through April 9, 2014, was 34% (25/74 patients) in the PAG 
arm and 23% in the AG arm (14/61 patients) (P=0.17). Among the safety evaluable patients with baseline HA staining and at least one protocol 
specified post base line scan after two cycles of study drug to assess tumor response (62 patients), the objective response rate was 60% in the 
PAG arm (21/35 patients), and 37% in the AG arm (10/27 patients) (P=0.09). In patients with high base line tumor staining for HA the objective 
response rate was 71% in the PAG arm (12/17 patients), and 29% in the AG arm (5/17 patients) (P=0.016). To assess PFS data for all Stage 1 
patients who had received at least one dose of drug and had a base line HA analysis (106 patients), data was evaluated through December 9, 
2014 to allow for sufficient follow up duration. Per the description above, patients in the PAG arm all discontinued PEGPH20 in April and only 
a portion restarted PEGPH20 in July 2014 upon the lift of the clinical hold. The PFS in this population was 5.5 months in the PAG arm vs 4.8 
months in the AG arm (p=0.086). In patients with high base line tumor staining for HA, the PFS was 9.2 months in the PAG arm (12/25 patients) 
vs 4.3 months in the AG arm (15/23 patients) (P=0.031).  

We and the data monitoring committee for Study 109-202 continue to closely monitor the occurrence of thromboembolic events in enrolled 
patients after the revision to the protocol. The revised protocol includes pre-specified analyses to evaluate the rate of thromboembolic events, 
and Study 109-202 may be halted again if the protocol changes do not result in a reduction of thromboembolic events in accordance with the pre-
specified analyses in the protocol.  

SWOG Study S1313 :  

In October 2013, SWOG, a cancer research cooperative group of more than 4,000 researchers in over 500 institutions around the world, 
initiated a 144 patient Phase 1b/2 randomized clinical trial in some of their study centers, examining PEGPH20 in combination with modified 
FOLFIRINOX  chemotherapy  (mFOLFIRINOX)  compared  to  mFOLFIRINOX  treatment  alone  in  patients  with  metastatic  pancreatic 
adenocarcinoma (funded by the National Cancer Institute). This study was also placed on clinical hold temporarily at the time of the hold on 
Study  109-202.  In  September  2014,  the FDA  removed  the  clinical  hold  on  patient  enrollment  and  dosing  of  PEGPH20  in  this  SWOG 
cooperative study. The study has resumed under a revised protocol, and patient enrollment is continuing. As with Study 109-202, the occurrence 
of thromboembolic events will be closely monitored in enrolled patients, and the continuation of this study may be halted again in accordance 
with event rate rules established in the protocol, or for other safety reasons.  

Other indications outside of pancreatic cancer :  

Study  HALO  107-201,  PRIMAL  Study  :  In  December  2014,  we  initiated  a  Phase  1b/2  trial,  to  evaluate  PEGPH20  in  second  line  in 
combination with docetaxel (Taxotere ® ) in Non-Small Cell Lung Cancer (NSCLC) patients. In this study, we expect to evaluate and identify the 
dose, dosing regimen and safety of PEGPH20 plus docetaxel in previously treated patients with NSCLC. Upon identification of the dose and 
dosing regimen, we plan to expand the trial to evaluate safety and efficacy.

Study HALO 107-101, the immuno-oncology trial: In the second half of 2015, we plan to initiate an immuno-oncology trial, exploring the 
combination of PEGPH20 and an immune-oncology agent such as a PD1/PDL1 inhibitor. We expect to evaluate and identify the dose and safety 
of PEGPH20 plus the immune-oncology agent prior to embarking on expansion into multiple tumors including NSCLC and Gastric cancers.  

Regulatory :  

In September 2014, the FDA granted Fast Track designation for our program investigating PEGPH20 in combination with gemcitabine and 
nab-paclitaxel for the treatment of patients with metastatic pancreatic cancer to demonstrate an improvement in overall survival. The Fast Track 
designation process was developed by the FDA to facilitate the development, and expedite the review of drugs to treat serious or life-threatening 
diseases and address unmet medical needs.  

In  October  2014,  the FDA  granted  Orphan  Drug  designation  for  PEGPH20  for  the  treatment  of  pancreatic  cancer. The  FDA  Office  of 
Orphan Products Development mission is to advance the evaluation and development of products (drugs, biologics, devices, or medical foods) 
that  demonstrate  promise  for  the  diagnosis  and/or  treatment  of  rare  diseases  or  conditions.  In  December  2014,  the  European  Committee  for 
Orphan Medicinal Products of the EMA designated PEGPH20 an orphan medicinal product for the treatment of pancreatic cancer.  

In  the  first  quarter  of  2015,  we  plan  to  meet  with  the  Health  authorities  in  the  U.S.,  and  subsequently  in  Europe,  to  discuss  a  potential 
registration  seeking  study  in  stage  IV  metastatic  pancreatic  cancer  patients  whose  tumors  are  determined  to  have  high  levels  of  HA 
accumulation.  In  the  first  half  of  2015,  we  also  plan  to  engage  the  health  authorities  for  development  of  a  companion  diagnostic  agent  for 
detection and qualification of hyaluronan in the tumor tissue of cancer patients.  

In  October  2014,  we  announced  the  issuance  of  U.S.  Patent  No.  8,846,034  claiming methods  for  selecting  a  subject  for  treatment  of  a 
hyaluronan-associated disease with an anti-hyaluronan agent, such as PEGPH20, as well as diagnostic agents for the detection and quantification 
of hyaluronan in a biological sample in patients.  

Ultrafast Insulin Program Evaluation of rHuPH20 and Hylenex in Patients with Diabetes  

Two  distinct  opportunities  exist  for  the  use  of  rHuPH20  and  Hylenex  recombinant  in  diabetes.  We  intend  to  seek  to  enter  into 

collaborations with third parties or explore other strategic alternatives in order to exploit these opportunities.  

The  first  opportunity,  Continuous  Subcutaneous  Insulin  Infusion  (CSII),  is  focused  on  assessing  the  effects  of  pre-treating  the  insulin 
infusion  site with Hylenex  recombinant at the  time  of  infusion  site  change (once  every  3 days).  Insulin  pump therapy  is growing  in  the  U.S. 
among patients with type 1 and type 2 diabetes and the focus of our program is type 1. We believe that the pre-treatment of the infusion site with 
Hylenex recombinant could result in faster onset and shorter duration of insulin action.  

In the first quarter of 2013, we initiated CONSISTENT 1, a clinical trial evaluating the safety and efficacy of Hylenex recombinant and a 
new formulation of  Hylenex  when used as pretreatment of the insulin infusion site in patients with type 1 diabetes. With enrollment completed 
in the third quarter of 2013, the trial has enrolled 456 patients with type 1 diabetes who were randomized 3:1 to either rapid acting analog insulin 
(RAI) delivered by CSII with Hylenex recombinant pretreatment of the infusion site or standard CSII using RAI alone. Subjects randomized to 
the Hylenex recombinant group were administered 150 units of Hylenex recombinant once every three days through each new infusion cannula, 
immediately prior to initiation of insulin delivery. In June 2014, we presented a scientific poster highlighting the CONSISTENT 1 trial results at 
the 74th Scientific Sessions of the American Diabetes Association in San Francisco. Data reported in the presentation showed that the study's 
primary endpoint of non-inferiority for A1C at six months between the use of Hylenex and the new formulation of Hylenex in comparison to no 
pre-treatment, was met. In addition to other trial data, the poster also presented data indicating that there was a potential reduction in the rate of 
some types of hypoglycemic events associated with the use of the Hylenex formulations in comparison to no pre-treatment. The most common 
treatment related adverse event in the Hylenex recombinant groups was mild infusion site discomfort. With this exception, adverse events were 
similar across the treatment and control groups.  

6  

 
 
 
 
In  parallel  with  our  clinical  activities,  we  have  been  in  dialog  with  the  FDA  regarding  the  requirements  for  updating  the  Hylenex 
recombinant label in a manner that would support future promotion in this indication. While discussions with the FDA are ongoing, we have 
learned that the FDA will likely request additional clinical data for a label update, translating to potentially higher projected costs and longer 
time  to  market  than  we  had  originally  anticipated.  We  are  continuing  to  seek  clarity  with  the  FDA  on  what  data  will  be  required,  if  any.  In 
addition, we determined in the fourth quarter 2014 that with all patients having completed 12 months on the trial, we did not need additional data 
contribution from the second year of the CONSISTENT 1 trial, and we stopped the trial and are currently summarizing the data for all patients 
treated for 12 months. After evaluating our options, we have decided that except for any costs in connection with closing out the CONSISTENT 
1 trial, we do not intend to incur substantial additional expenses for the program.  

The second opportunity, Multiple Daily Injection (MDI), is to combine rHuPH20 with an FDA approved RAI, e.g., insulin lispro (Humalog 
® ) (Lispro-PH20), insulin aspart (Novolog ® ) (Aspart-PH20) and insulin glulisine (Apidra ® ) (Glulisine-PH20), (each such combination, analog-
PH20),  to  seek  to  accelerate  their  action.  A  number  of  clinical  trials  investigating  the  various  attributes  of  our  product  candidates  have  been 
completed,  with  the  last  study  completed  in  2011.  Since  then  we  have  only  conducted  limited  additional  development  work  with  this 
opportunity.  

Data from two treatment studies - one in type 1 diabetes patients and one in type 2 diabetes patients has been published. Copies of these 
publications can be found at http://www.halozyme.com/Technology/Journals-Abstracts-And-Posters/default.aspx . Both studies met their primary 
endpoints  of  A1C  non-inferiority  and  improved  post-prandial  glucose  control  compared  to  patients  who  were  treated  with  RAI  alone. 
Additionally, data from the type 1 diabetes treatment study indicated that Analog-PH20 formulations reduced hypoglycemia compared to RAI 
alone.  

Collaborations  

Roche Collaboration  

In December 2006, we and Roche entered into an agreement under which Roche obtained a worldwide, exclusive license to develop and 
commercialize product combinations of rHuPH20 with up to thirteen Roche target compounds (the Roche Collaboration). Roche initially had the 
exclusive right to apply rHuPH20 to only three pre-defined Roche biologic targets with the option to exclusively  develop and commercialize 
rHuPH20  with  ten additional targets.  As of December 31,  2014  ,  Roche  has  elected a  total  of  five exclusive  targets  and  retains the  option  to 
develop and commercialize rHuPH20 with three additional targets through the payment of annual license maintenance fees.  

In September 2013, Roche launched a SC formulation of Herceptin (trastuzumab) (Herceptin SC) in Europe for the treatment of patients 
with HER2-positive breast cancer. This formulation utilizes our patented Enhanze technology and is administered in two to five minutes, rather 
than 30 to 90 minutes with the standard intravenous form. Roche received European marketing approval for Herceptin SC in August 2013. The 
European Commission’s approval was based on data from Roche’s Phase 3 HannaH study which showed that the subcutaneous formulation of 
Herceptin was associated with comparable efficacy (pathological complete response, pCR) to Herceptin administered intravenously in women 
with HER2-positive early breast cancer and resulted in non-inferior trastuzumab plasma levels. Overall, the safety profile in both arms of the 
HannaH study was consistent with that expected from standard treatment with Herceptin and chemotherapy in this setting. No new safety signals 
were identified. Breast cancer is the most common cancer among women worldwide. Each year, about 1.4 million new cases of breast cancer are 
diagnosed  worldwide,  and  over  450,000  women  will  die  of  the  disease  annually.  In  HER2-positive  breast  cancer,  increased  quantities  of  the 
human epidermal growth factor receptor 2 (HER2) are present on the surface of the tumor cells. This is known as “HER2 positivity” and affects 
approximately 15% to 20% of women with breast cancer. HER2-positive cancer is reported to be a particularly aggressive form of breast cancer.

In  June  2014,  Roche  launched  MabThera  ®  SC  in  Europe  for  the  treatment  of  patients  with  common  forms  of  non-Hodgkin  lymphoma 
(NHL).  This  formulation  utilizes  our  patented  Enhanze  technology  and  is  administered  in  approximately  five  minutes  compared  to  the 
approximately  2.5  hour  infusion  time  for  intravenous  MabThera.  The  European  Commission  approved  MabThera  SC  in  March  2014.  The 
European Commission's approval was based primarily on data from Roche's Phase 3 pivotal clinical studies, which was recently published in 
The  Lancet  Oncology.  NHL  is  a  type  of  cancer  that  affects  lymphocytes  (white  blood  cells).  NHL  represents  approximately  85%  of  all 
lymphomas  diagnosed  and  was  responsible  for  approximately  200,000  annual  deaths  worldwide  in  2012.  Lymphomas  are  a  cancer  of  the 
lymphatic system (composed of lymph vessels, lymph nodes and organs) which helps to keep the bodily fluid levels balanced and to defend the 
body against invasion by disease. Lymphoma develops when white blood cells (usually B-lymphocytes) in the lymph fluid become cancerous 
and  begin  to  multiply  and  collect  in  the  lymph  nodes  or  lymphatic  tissues  such  as  the  spleen.  Some  of  these  cells  are  released  into  the 
bloodstream and spread around the body, interfering with the body's production of healthy blood cells.  

Additional information about the Phase 3 Herceptin SC and Phase 3 MabThera SC clinical trials can be found at www.clinicaltrials.gov 

and www.roche-trials.com . Information available on these websites is not incorporated into this report.  

Baxter Collaboration  

In September 2007, we and Baxter entered into an agreement under which Baxter obtained a worldwide, exclusive license to develop and 
commercialize  product  combinations  of  rHuPH20  with  GAMMAGARD  LIQUID  (HYQVIA)  (the  Baxter  Collaboration).  GAMMAGARD 
LIQUID  is  a  current Baxter  product  that  is  indicated  for  the  treatment  of  primary  immunodeficiency  disorders  associated  with  defects  in  the 
immune system.  

In  October  2014,  Baxter  announced  the  launch  and  first  shipments  of  Baxter’s  HYQVIA  product  for  treatment  of  adult  patients  with 
primary  immunodeficiency  in  the  U.S.  HYQVIA  was  approved  by  the  FDA  in  September  2014  and  is  the  first  subcutaneous  IG  treatment 
approved for adult primary immunodeficiency patients with a dosing regimen requiring only one infusion up to once per month (every three to 
four  weeks)  and  one  injection  site  per  infusion  in  most  patients,  to  deliver  a  full  therapeutic  dose  of  IG.  The  majority  of  primary 
immunodeficiency patients today receive intravenous infusions in a doctor’s office or infusion center, and current subcutaneous IG treatments 
require weekly or bi-weekly treatment with multiple infusion sites per treatment. The FDA's approval of HYQVIA is a significant milestone for 
us as it represents the first U.S. approved BLA which utilizes our rHuPH20 platform.  

In  May  2013,  the  European  Commission  granted  Baxter  marketing  authorization  in  all  EU  Member  States  for  the  use  of  HYQVIA 
(solution  for  subcutaneous  use)  as  replacement  therapy  for  adult  patients  with  primary  and  secondary  immunodeficiencies.  Baxter  launched 
HYQVIA in the first EU country in July 2013 and in additional EU countries in the second half of 2013 and in 2014.  

Pfizer Collaboration  

In  December  2012,  we  and  Pfizer  entered  into  a  collaboration  and  license  agreement,  under  which  Pfizer  has  the  worldwide  license  to 
develop and commercialize products combining our rHuPH20 enzyme with Pfizer proprietary biologics directed to up to six targets in primary 
care and specialty care indications. Targets may be selected on an exclusive or non-exclusive basis. In September 2013, Pfizer elected the fourth 
therapeutic target on an exclusive basis. In  December 2013, Pfizer announced that one of the targets is proprotein convertase subtilisin/kexin 
type 9, also known as PCSK9. The PCSK9 gene provides instructions for making a protein that helps regulate the amount of cholesterol in the 
bloodstream. Pfizer is also developing Rivipansel directed to another target under the collaboration to treat vaso-occlusive crisis in individuals 
with sickle cell disease.  

Janssen Collaboration  

In December 2014, we and Janssen entered into a collaboration and license agreement, under which Janssen has the worldwide license to 
develop and commercialize products combining our rHuPH20 enzyme with Janssen proprietary biologics directed to up to five targets. Targets 
may be selected on an exclusive or non-exclusive basis. Janssen has elected one undisclosed target on an exclusive basis.

Patents and Proprietary Rights  

Patents and other proprietary rights are essential to our business. Our success will depend in part on our ability to obtain patent protection 
for our inventions, to preserve our trade secrets and to operate without infringing the proprietary rights of third parties. Our strategy is to actively 
pursue patent protection in the U.S. and certain foreign jurisdictions for technology that we believe to be proprietary to us and that offers us a 
potential competitive advantage. Our patent portfolio includes 20 issued patents in the U.S., 80 issued patents in Europe and other countries in 
the world and a number of pending patent applications. In general, patents have a term of 20 years from the application filing date or earlier 
claimed priority date. Our issued patents will expire between 2022 and 2032. We have multiple patents and patent applications throughout the 
world pertaining to our recombinant human hyaluronidase and methods of use and manufacture, including an issued U.S. patent which expires in 
2027  and  an  issued  European  patent  which  expires  in  2024,  which  we  believe  cover  the  products  and  product  candidates  under  our  existing 
collaborations, Hylenex recombinant, PEGPH20 and our endocrinology product candidates. In addition, we have, under prosecution throughout 
the world, multiple patent applications that relate specifically to individual product candidates under development, the expiration of which can 
only  be  definitely  determined upon maturation  into our  issued  patents. We believe our patent filings  represent  a barrier  to entry for  potential 
competitors looking to utilize these hyaluronidases.  

In  addition  to  patents,  we  rely  on  unpatented  trade  secrets,  proprietary  know-how  and  continuing  technological  innovation.  We  seek 
protection of these trade secrets, proprietary know-how and innovation, in part, through confidentiality and proprietary information agreements. 
Our policy is to require our employees, directors, consultants, advisors, collaborators, outside scientific collaborators and sponsored researchers, 
other  advisors  and  other  individuals  and  entities  to  execute  confidentiality  agreements  upon  the  start  of  employment,  consulting  or  other 
contractual  relationships  with  us.  These  agreements  provide  that  all  confidential  information  developed  or  made  known  to  the  individual  or 
entity during the course of the relationship is to be kept confidential and not disclosed to third parties except in specific circumstances. In the 
case of employees and some other parties, the agreements provide that all inventions conceived by the individual will be our exclusive property. 
Despite  the  use  of  these  agreements  and  our  efforts  to  protect  our  intellectual  property,  there  will  always  be  a  risk  of  unauthorized  use  or 
disclosure of information. Furthermore, our trade secrets may otherwise become known to, or be independently developed by, our competitors.  

We also file trademark applications to protect the names of our products and product candidates. These applications may not mature to 
registration and may be challenged by third parties. We are pursuing trademark protection in a number of different countries around the world. 
There can be no assurances that our registered or unregistered trademarks or trade names will not infringe on rights of third parties or will be 
acceptable to regulatory agencies.  

Research and Development Activities  

Our  research  and  development  expenses  consist  primarily  of  costs  associated  with  the  development  and  manufacturing  of  our  product 
candidates, compensation and other expenses for research and development personnel, supplies and materials, costs for consultants and related 
contract research, clinical trials, facility costs and amortization and depreciation. We charge all research and development expenses to operations 
as they are incurred. Our research and development activities are primarily focused on the development of our various product candidates.

Due to the uncertainty in obtaining the FDA and other regulatory approvals, our reliance on third parties and competitive pressures, we are 
unable to estimate with any certainty the additional costs we will incur in the continued development of our proprietary product candidates for 
commercialization.  However,  we  expect  our  research  and  development  expenses  for  PEGPH20  to  increase  as  our  program  advances  into 
additional tumors and later stages of clinical development.  

Manufacturing  

We do not have our own manufacturing facility for our product and product candidates, or their active pharmaceutical ingredient (API) or 
bulk  forms,  or  the capability  to  package  our product.  We  have  engaged  third parties  to manufacture  bulk rHuPH20 and our product Hylenex 
recombinant.  

We have existing supply agreements with contract manufacturing organizations Avid Bioservices, Inc. (Avid) and Cook Pharmica LLC 
(Cook) to produce supplies of bulk rHuPH20. These manufacturers each produce bulk rHuPH20 under current Good Manufacturing Practices 
(cGMP)  for  clinical  and  commercial  uses.  Avid  and  Cook  currently  produce  bulk  rHuPH20  for  use  in  Hylenex  recombinant  and  our  other 
collaboration  products  and  product  candidates.  We  rely  on  their  ability  to  successfully  manufacture  these  batches  according  to  product 
specifications. Cook has limited experience manufacturing bulk rHuPH20. In addition, we have been working to scale-up, validate and qualify 
Cook as a manufacturer of bulk rHuPH20 for use in the product and product candidates under the Roche collaboration. To date, Cook has not 
been submitted to the European regulatory authorities by Roche as an approved manufacturer for Herceptin SC and MabThera SC. It is essential 
for  our  business  for  Cook  and  Avid  to  (i) retain  their  status  as  cGMP-approved  manufacturing  facilities;  (ii) to  successfully  scale  up  bulk 
rHuPH20  production;  and/or  (iii) manufacture  the  bulk  rHuPH20  required  by  us  and  our  collaborators  for  use  in  our  proprietary  and 
collaboration  products  and  product  candidates.  In  addition  to  supply  obligations,  Avid  and  Cook  will  also  provide  support  for  data  and 
information used in the chemistry, manufacturing and controls sections for FDA and other regulatory filings.  

We have a commercial manufacturing and supply agreement with Baxter, a cGMP-approved manufacturing facility, under which Baxter 
provides the final fill and finishing steps in the production process of Hylenex recombinant. Under our commercial manufacturing and supply 
agreement  with  Baxter,  Baxter  has  agreed  to  fill  and  finish  Hylenex  recombinant  product  for  us  until  December  31,  2017,  subject  to  further 
extensions  in  accordance  with  the  terms  of  the  agreement.  In  June  2011,  we  entered  into  a  services  agreement  with  another  third  party 
manufacturer, Patheon Manufacturing Services, LLC (Patheon), for the technology transfer and manufacture, fill, finish or packaging of Hylenex 
recombinant. In October 2014, we received regulatory approval from the FDA for Patheon to manufacture Hylenex recombinant. In December 
2014, we entered into a manufacturing services agreement with Patheon under which Patheon will provide the final fill and finishing steps in the 
production  process  of  Hylenex  recombinant.  Under  our  commercial  services  agreement  with  Patheon,  Patheon  has  agreed  to  fill  and  finish 
Hylenex recombinant product for us until December 31, 2019, subject to further extensions in accordance with the terms of the agreement. In 
2015, we will begin to transition our manufacturing supply to Patheon to achieve higher capacity and lower cost of goods.  

Sales, Marketing and Distribution  

HYLENEX Recombinant  

Our commercial activities currently focus on Hylenex recombinant. We have a team of sales specialists that provide hospital and surgery 
center  customers  with  the  information  about  Hylenex  recombinant  and  information  needed  to  obtain  formulary  approval  for,  and  support 
utilization of, Hylenex recombinant. Our commercial activities also include marketing and related services and commercial support services such 
as  commercial  operations,  managed  markets  and  commercial  analytics.  We  also  employ  third-party  vendors,  such  as  advertising  agencies, 
market research firms and suppliers of marketing and other sales support related services to assist with our commercial activities.  

We sell Hylenex recombinant in the U.S. to wholesale distributors, who sell to hospitals, ambulatory surgery centers and other end-users. 
We  have  engaged  Integrated  Commercial  Solutions  (ICS),  a  division  of  AmerisourceBergen  Specialty  Group,  a  subsidiary  of 
AmerisourceBergen, to act as our exclusive distributor for commercial shipment and distribution of Hylenex recombinant to our customers in the 
United  States.  In  addition  to  distribution  services,  ICS  provides  us  with  other  key  services  related  to  logistics,  warehousing,  returns  and 
inventory management, contract administration and chargebacks processing and accounts receivable management. In addition, we utilize third 
parties to perform various other services for us relating to regulatory  

10  

 
 
 
 
monitoring, including call center management, adverse event reporting, safety database management and other product maintenance services.  

Competition  

The pharmaceutical industry is characterized by rapidly advancing technologies, intense competition and a strong emphasis on proprietary 
therapeutics.  We  face  competition  from  a  number  of  sources,  some  of  which  may  target  the  same  indications  as  our  product  or  product 
candidates,  including  large  pharmaceutical  companies,  smaller  pharmaceutical  companies,  biotechnology  companies,  academic  institutions, 
government agencies and private and public research institutions, many of which have greater financial resources, drug development experience, 
sales and marketing capabilities, including larger, well established sales forces, manufacturing capabilities, experience in obtaining regulatory 
approvals for product candidates and other resources than us. We face competition not only in the commercialization of Hylenex recombinant, 
but also for the in-licensing or acquisition of additional product candidates, and the out-licensing of our Enhanze technology. In addition, our 
collaborators face competition in the commercialization of the product candidates for which the collaborators seek marketing approval from the 
FDA or other regulatory authorities.  

HYLENEX Recombinant  

Hylenex recombinant is currently the only FDA-approved recombinant human hyaluronidase on the market. The competitors for Hylenex 
recombinant  include,  but  are  not  limited  to,  Bausch  &  Lomb  Inc.'s  FDA-approved  product,  Vitrase  ®  ,  an  ovine  (ram)  hyaluronidase,  and 
Amphastar Pharmaceuticals, Inc.'s product, Amphadase ® , a bovine (bull) hyaluronidase, which is not currently on the market. In addition, some 
commercial  pharmacies  compound  hyaluronidase  preparations  for  institutions  and  physicians  even  though  compounded  preparations  are  not 
FDA-approved products.  

Government Regulations  

The FDA and comparable regulatory agencies in foreign countries regulate the manufacture and sale of the pharmaceutical products that 
we have developed or currently are developing. The FDA has established guidelines and safety standards that are applicable to the laboratory 
and  preclinical  evaluation  and clinical investigation of  therapeutic  products and  stringent  regulations  that govern the manufacture and  sale  of 
these  products.  The  process of obtaining regulatory approval for  a new therapeutic  product  usually requires  a significant amount  of  time and 
substantial resources. The steps typically required before a product can be introduced for human use include:  

•  

•  

animal pharmacology studies to obtain preliminary information on the safety and efficacy of a drug; or 

laboratory and preclinical evaluation in vitro and in vivo including extensive toxicology studies. 

The results of these laboratory and preclinical studies may be submitted to the FDA as part of an IND application. The sponsor of an IND 

application may commence human testing of the compound 30 days after submission of the IND, unless notified to the contrary by the FDA.  

The clinical testing program for a new drug typically involves three phases:  

•   Phase  1  investigations  are  generally  conducted  in  healthy  subjects  (in  certain  instances,  Phase  1  studies  that  determine  the  maximum 

tolerated dose and initial safety of the product candidate are performed in patients with the disease);  

•   Phase 2 studies are conducted in limited numbers of subjects with the disease or condition to be treated and are aimed at determining the 
most  effective  dose  and  schedule  of  administration,  evaluating  both  safety  and  whether  the  product  demonstrates  therapeutic 
effectiveness against the disease; and  

•   Phase 3 studies involve large, well-controlled investigations in diseased subjects and are aimed at verifying the safety and effectiveness 

of the drug.  

11  

 
 
 
 
Data from all clinical studies, as well as all laboratory and preclinical studies and evidence of product quality, are typically submitted to 
the FDA in a new drug application (NDA). The results of the preclinical and clinical testing of a biologic product candidate are submitted to the 
FDA in the form of a BLA, for evaluation to determine whether the product candidate may be approved for commercial sale. In responding to a 
BLA  or  NDA,  the  FDA  may  grant  marketing  approval,  request  additional  information,  or  deny  the  application.  Although  the  FDA’s 
requirements for clinical trials are well established and we believe that we have planned and conducted our clinical trials in accordance with the 
FDA’s applicable regulations and guidelines, these requirements, including requirements relating to testing the safety of drug candidates, may be 
subject  to  change as a  result  of recent  announcements regarding safety  problems with approved  drugs. Additionally,  we could be required  to 
conduct additional trials beyond what we had planned due to the FDA’s safety and/or efficacy concerns or due to differing interpretations of the 
meaning of our clinical data. (See Part I, Item 1A, Risk Factors. )  

The FDA’s Center for Drug Evaluation and Research must approve an NDA and the FDA’s Center for Biologics Evaluation and Research 
must approve a BLA for a drug before it may be marketed in the United States. If we begin to market our proposed products for commercial sale 
in the U.S., any manufacturing operations that may be established in or outside the U.S. will also be subject to rigorous regulation, including 
compliance with cGMP. We also may be subject to regulation under the Occupational Safety and Health Act, the Environmental Protection Act, 
the Toxic Substance Control Act, the Export Control Act and other present and future laws of general application. In addition, the handling, care 
and  use  of  laboratory  animals  are  subject  to  the  Guidelines  for  the  Humane  Use  and  Care  of  Laboratory  Animals  published  by  the  National 
Institutes of Health.  

Regulatory obligations continue post-approval, and include the reporting of adverse events when a drug is utilized in the broader patient 
population. Promotion and marketing of drugs is also strictly regulated, with penalties imposed for violations of FDA regulations, the Lanham 
Act and other federal and state laws, including the federal anti-kickback statute.  

We currently intend to continue to seek, directly or through our collaborators, approval to market our products and product candidates in 
foreign  countries,  which  may  have  regulatory  processes  that  differ  materially  from  those  of  the  FDA.  We  anticipate  that  we  will  rely  upon 
independent consultants to seek and gain approvals to market our proposed products in foreign countries or may rely on other pharmaceutical or 
biotechnology companies to license our proposed products. We cannot assure you that approvals to market any of our proposed products can be 
obtained in any country. Approval to market a product in any one foreign country does not necessarily indicate that approval can be obtained in 
other countries.  

From time to time, legislation is drafted and introduced in Congress that could significantly change the statutory provisions governing the 
approval, manufacturing and marketing of drug products. In addition, FDA regulations and guidance are often revised or reinterpreted by the 
agency or reviewing courts in ways that may significantly affect our business and development of our product candidates and any products that 
we  may  commercialize.  It  is  impossible  to  predict  whether  additional  legislative  changes  will  be  enacted,  or  FDA  regulations,  guidance  or 
interpretations changed, or what the impact of any such changes may be.  

Segment Information  

We  operate  our  business  as  one  segment,  which  includes  all  activities  related  to  the  research,  development  and  commercialization  of 
human  enzymes.  This  segment  also  includes  revenues  and  expenses  related  to  (i) research  and  development  activities  conducted  under  our 
collaboration  agreements  with  third  parties  and  (ii) product  sales  of  Hylenex  recombinant.  The  chief  operating  decision-maker  reviews  the 
operating results on an aggregate basis and manages the operations as a single operating segment. We had no foreign based operations and no 
long-lived assets located in foreign countries as of and for the years ended December 31, 2014, 2013 and 2012 . Refer to the Notes for additional 
financial information regarding our operating segment.  

Executive Officers of the Registrant  

Information concerning our executive officers, including their names, ages and certain biographical information can be found in Part III, 

Item 10, Directors, Executive Officers and Corporate Governance . This information is incorporated by reference into Part I of this report.

Employees  

As of February 24, 2015 , we had 153 full-time employees. None of our employees are unionized and we believe our employee relations to 

be good.  

Item 1A.   Risk Factors 

Risks Related To Our Business  

We have generated only limited revenue from product sales to date; we have a history of net losses and negative cash flow, and we may 
never achieve or maintain profitability.  

Relative  to  expenses  incurred  in  our  operations,  we  have  generated  only  limited  revenues  from  product  sales,  royalties,  licensing  fees, 
milestone payments, bulk rHuPH20 supply payments and research reimbursements to date and we may never generate sufficient revenues from 
future  product  sales,  licensing  fees  and  milestone  payments  to  offset  expenses.  Even  if  we  ultimately  do  achieve  significant  revenues  from 
product sales, royalties, licensing fees, research reimbursements, bulk rHuPH20 supply payments and/or milestone payments, we expect to incur 
significant  operating  losses  over  the  next  few  years.  We  have  never  been  profitable,  and  we  may  never  become  profitable.  Through 
December 31, 2014 , we have incurred aggregate net losses of approximately $450.4 million .  

If  our  product  candidates  do  not  receive  and  maintain  regulatory  approvals,  or  if  approvals  are  not  obtained  in  a  timely  manner,  such 
failure or delay would substantially impair our ability to generate revenues.  

Approval from the FDA or equivalent health authorities is necessary to manufacture and market pharmaceutical products in the U.S. and 
the  other  countries  in  which  we  anticipate  doing  business  have  similar  requirements.  The  process  for  obtaining  FDA  and  other  regulatory 
approvals is extensive, time-consuming, risky and costly, and there is no guarantee that the FDA or other regulatory bodies will approve any 
applications that may be filed with respect to any of our product candidates, or that the timing of any such approval will be appropriate for the 
desired product launch schedule for a product candidate. We and our collaborators attempt to provide guidance as to the timing for the filing and 
acceptance of such regulatory approvals, but such filings and approvals may not occur when we or our collaborators expect, or at all. The FDA 
or  other  foreign  regulatory  agency  may  refuse  or  delay  approval  of  our  product  candidates  for  failure  to  collect  sufficient  clinical  or  animal 
safety  data  and  require  us  or  our  collaborators  to  conduct  additional  clinical  or  animal  safety  studies  which  may  cause  lengthy  delays  and 
increased costs to our programs. For example, we have been in dialog with the FDA regarding the regulatory pathway and data requirements for 
updating the label for Hylenex recombinant for use in CSII but do not have clarity to date. However, we have learned that additional clinical data 
will likely be required for a label update. The lack of clarity has hampered our ability to develop and commercialize this opportunity and may 
impede our future ability to identify a strategic partner willing to invest in future development, registration and commercialization. In addition, 
the  approval  of  Baxter's  HYQVIA  BLA  was  delayed  until  we  and  Baxter  provided  additional  preclinical  data  sufficient  to  address  concerns 
regarding non-neutralizing antibodies to rHuPH20 that were detected in the registration trial. Although these antibodies have not been associated 
with any adverse clinical effects, and the HYQVIA BLA was approved by the FDA in September 2014, we cannot assure you that they will not 
arise and have an adverse impact on future development of products which include rHuPH20, future sales of Hylenex recombinant, our ability to 
enter  into  collaborations,  or  be  raised  by  the  FDA  or  other  health  authorities  in  connection  with  testing  or  approval  of  products  including 
rHuPH20.  

Only  three  of  our  collaboration  product  candidates  and  one  of  our  proprietary  products  have  been  approved  for  commercialization.  We 
have no proprietary product candidates currently in the regulatory approval process. We and our collaborators may not be successful in obtaining 
approvals for  any potential products  in  a timely manner, or at all.  Refer to the risk  factor titled  “ Our proprietary and collaboration product 
candidates may not receive regulatory approvals or their development may be delayed for a variety of reasons, including unsuccessful clinical 
trials, regulatory requirements or safety concerns ” for additional information relating to the approval of product candidates.  

Additionally,  even  with  respect  to  products  which  have  been  approved  for  commercialization,  in  order  to  continue  to  manufacture  and 
market  pharmaceutical  products,  we  or  our  collaborators  must  maintain  our  regulatory  approvals.  If  we  or  any  of  our  collaborators  are 
unsuccessful in maintaining our regulatory approvals, our ability to generate revenues would be adversely affected.  

13  

 
 
 
 
Use of our product candidates or those of our collaborators could be associated with side effects or adverse events.  

As with most pharmaceutical products, use of our product candidates or those of our collaborators could be associated with side effects or 
adverse events which can vary in severity (from minor reactions to death) and frequency (infrequent or prevalent). Side effects or adverse events 
associated with the use of our product candidates or those of our collaborators may be observed at any time, including in clinical trials or when a 
product  is  commercialized,  and  any  such  side  effects  or  adverse  events  may  negatively  affect  our  or  our  collaborators'  ability  to  obtain  or 
maintain regulatory approval or market our product candidates. Side effects such as toxicity or other safety issues associated with the use of our 
product candidates or those of our collaborators could require us or our collaborators to perform additional studies or halt development or sale of 
these product candidates or expose us to product liability lawsuits which will harm our business. We or our collaborators may be required by 
regulatory agencies to conduct additional animal or human studies regarding the safety and efficacy of our pharmaceutical product candidates 
which we have not planned or anticipated. Furthermore, there can be no assurance that we or our collaborators will resolve any issues related to 
any product related adverse events to the satisfaction of the FDA or any regulatory agency in a timely manner or ever, which could harm our 
business,  prospects  and  financial  condition.  For  example,  in  April  2014,  a  clinical  hold  was  placed  on  patient  enrollment  and  dosing  of 
PEGPH20  in  Study  202  as  a result  of  a  possible  difference in  the  thromboembolic  event  rate  that  had  been  observed  at  that  time  in the  trial 
between the  group  of patients treated  with  PEGPH20  versus the  group  of patients treated  without  PEGPH20.  The clinical  hold  was lifted  by 
FDA in June 2014, and we have resumed enrollment and dosing of PEGPH20 in Study 202 under a revised clinical protocol. We and the data 
monitoring committee for Study 202 continue to closely monitor the occurrence of thromboembolic events in enrolled patients after the protocol 
amendments. The continuation of Study 202 may be halted again if the protocol changes do not result in a reduction of thromboembolic events 
in accordance with event rate rules established in the protocol, or for other safety reasons.  

If our contract manufacturers are unable to manufacture and supply to us bulk rHuPH20 in the quantity and quality required by us or our 
collaborators for use in our products and product candidates, our product development and commercialization efforts could be delayed or 
stopped and our collaborations could be damaged.  

We  have  existing  supply  agreements  with  contract  manufacturing  organizations  Avid  Bioservices, Inc.  (Avid)  and  Cook  Pharmica  LLC 
(Cook)  to  produce  bulk  rHuPH20. These  manufacturers  each  produce  bulk  rHuPH20  under  current  cGMP  for  clinical  uses. Avid  and  Cook 
currently produce bulk rHuPH20 for use in Hylenex recombinant and certain other collaboration products and product candidates. In addition to 
supply  obligations,  Avid  and  Cook  will  also  provide  support  for  the  chemistry,  manufacturing  and  controls  sections  for  FDA  and  other 
regulatory  filings.  We  rely on their  ability  to  successfully  manufacture these batches  according  to  product  specifications.  Cook  has  relatively 
limited experience manufacturing bulk rHuPH20. In addition, we have been working to scale-up, validate and qualify Cook as a manufacturer of 
bulk  rHuPH20  for  use  in  the  product  and  product  candidates  under  the  Roche  collaboration.  To  date,  Cook  has not  been  submitted  to  the 
European regulatory authorities by Roche as an approved manufacturer for Herceptin SC and MabThera SC. If Cook is unable to obtain its status 
as an approved European manufacturing facility, or if either Avid or Cook: (i) is unable to retain its status as an FDA approved manufacturing 
facility; (ii) is unable to otherwise successfully scale up bulk rHuPH20 production to meet corporate or regulatory authority quality standards; or 
(iii) fails to manufacture and supply bulk rHuPH20 in the quantity and quality required by us or our collaborators for use in our proprietary and 
collaboration products and product candidates for any other reason, our business will be adversely affected. In addition, a significant change in 
such  parties'  business  or  financial  condition  could  adversely  affect  their  abilities  to  fulfill  their  contractual  obligations  to  us.  We  have  not 
established,  and  may  not  be  able  to  establish,  favorable  arrangements  with  additional  bulk  rHuPH20  manufacturers  and  suppliers  of  the 
ingredients necessary to manufacture bulk rHuPH20 should the existing manufacturers and suppliers become unavailable or in the event that our 
existing manufacturers and suppliers are unable to adequately perform their responsibilities. We have attempted to mitigate the impact of supply 
interruption through the establishment of excess bulk rHuPH20 inventory where possible, but there can be no assurances that this safety stock 
will be maintained or that  it  will  be  sufficient to  address any  delays, interruptions  or  other problems experienced by Avid and/or  Cook.  Any 
delays, interruptions or other problems regarding the ability of Avid and/or Cook to supply bulk rHuPH20 on a timely basis could: (i) cause the 
delay  of  clinical  trials  or  otherwise  delay  or  prevent  the  regulatory  approval  of  proprietary  or  collaboration  product  candidates;  (ii)  delay  or 
prevent the effective commercialization of proprietary or collaboration products; and/or (iii) cause us to breach contractual obligations to deliver 
bulk  rHuPH20  to  our  collaborators.  Such  delays  would  likely  damage  our  relationship  with  our  collaborators  under  our  key  collaboration 
agreements, and they would have a material adverse effect on royalties and thus our business and financial condition.  

14  

 
 
 
 
If we or any party to a key collaboration agreement fails to perform material obligations under such agreement, or if a key collaboration 
agreement, is terminated for any reason, our business could significantly suffer.  

We have entered into multiple collaboration agreements under which we may receive significant future payments in the form of milestone 
payments, target designation fees, maintenance fees and royalties. We are dependent on our collaborators to develop and commercialize product 
candidates  subject to  our  collaborations  in  order  for  us  to  realize  any financial  benefits from  these collaborations.  Our  collaborators  may  not 
devote the attention and resources to such efforts that we would to such efforts ourselves, change their promotional efforts or simultaneously 
develop and commercialize products in competition to those products we have licensed to them. Any of these actions could not be visible to us 
immediately and could negatively impact the benefits and revenue we receive from such collaboration. In addition, in the event that a party fails 
to perform under a key collaboration agreement, or if a key collaboration agreement is terminated, the reduction in anticipated revenues could 
delay or suspend our product development activities for some of our product candidates, as well as our commercialization efforts for some or all 
of our products. Specifically, the termination of a key collaboration agreement by one of our collaborators could materially impact our ability to 
enter into additional collaboration agreements with new collaborators on favorable terms, if at all. In certain circumstances, the termination of a 
key collaboration agreement would require us to revise our corporate strategy going forward and reevaluate the applications and value of our 
technology.  

Most  of  our  current  proprietary  and  collaboration  products  and  product  candidates  rely  on  the  rHuPH20  enzyme,  and  any  adverse 
development  regarding  rHuPH20  could  substantially  impact  multiple  areas  of  our  business,  including  current  and  potential 
collaborations, as well as proprietary programs.  

rHuPH20  is  a  key  technological  component  of  Enhanze  technology  and  our  most  advanced  proprietary  and  collaboration  products  and 
product candidates, including the current and future products and product candidates under our Roche, Pfizer, Janssen and Baxter collaborations, 
our  PEGPH20  program,  our  ultrafast  insulin  program  and  Hylenex  recombinant.  If  there  is  an  adverse  development  for  rHuPH20  (e.g.,  an 
adverse regulatory determination relating to rHuPH20, if we are unable to obtain sufficient quantities of rHuPH20, if we are unable to obtain or 
maintain material proprietary rights to rHuPH20 or if we discover negative characteristics of rHuPH20), multiple areas of our business, including 
current  and  potential  collaborations,  as  well  as  proprietary  programs  would  be  substantially  impacted.  For  example,  elevated  anti-rHuPH20 
antibody titers were detected in the registration trial for Baxter's HYQVIA product as well as in a former collaborator’s product in a Phase 2 
clinical trial with rHuPH20, but have not been associated, in either case, with any adverse events. We monitor for antibodies to rHuPH20 in our 
collaboration  and  proprietary  programs,  and  although  we  do  not  believe  at  this  time  that  the  incidence  of  non-neutralizing  anti-rHuPH20 
antibodies in either the HYQVIA program or the former collaborator’s program will have a significant impact on our other proprietary and other 
collaboration product candidates, there can be no assurance that there will not be other such occurrences in our other programs or that concerns 
regarding  these  antibodies  will  not  also  be  raised  by  the  FDA  or  other  health  authorities  in  the  future,  which  could  result  in  delays  or 
discontinuations of our development or commercialization activities or deter entry into additional collaborations with third parties.  

We routinely evaluate, and may modify, our business strategy and our strategic focus to only a few fields or applications of our technology 
which may increase or decrease the risk for potential negative impact of adverse developments.  

We routinely evaluate our business strategy, and may modify this strategy in the future in light of our assessment of unmet medical needs, 
growth potential, resource requirements, regulatory issues, competition, risks and other factors. As a result of these strategic evaluations, we may 
focus our  resources  and efforts on one  or  a few  programs  or  fields and may  suspend  or  reduce our  efforts  on  other programs and fields.  For 
example,  in  the  third  quarter  of  2014,  we  decided  to  focus  our  resources  on  advancing  PEGPH20  and  expanding  utilization  of  our  Enhanze 
platform.  While  we  believe  these  are  applications  with  the  greatest  potential  value,  we  have  reduced  the  diversification  of  our  programs  and 
increased our dependence on the success of the areas we are pursuing. By focusing on one or a few areas, we increase the potential impact on us 
if  one  of  those  programs  or  product  candidates  does  not  successfully  complete  clinical  trials,  achieves  commercial  acceptance  or  meets 
expectations regarding sales and revenue. Our decision to focus on one or a few programs may also reduce the value of programs that are no 
longer  within  our  principal  strategic  focus,  which  could  impair  our  ability  to  pursue  collaborations  or  other  strategic  alternatives  for  those 
programs we are not pursuing.  

15  

 
 
 
 
Our  proprietary  and  collaboration  product  candidates  may  not  receive  regulatory  approvals  or  their  development  may  be  delayed  for  a 
variety of reasons, including unsuccessful clinical trials, regulatory requirements or safety concerns.  

Clinical testing of pharmaceutical products is a long, expensive and uncertain process, and the failure or delay of a clinical trial can occur at 
any stage. Even if initial results of preclinical and nonclinical studies or clinical trial results are promising, we or our collaborators may obtain 
different results in subsequent trials or studies that fail to show the desired levels of safety and efficacy, or we may not, or our collaborators may 
not, obtain applicable regulatory approval for a variety of other reasons. Preclinical, nonclinical, and clinical trials for any of our proprietary or 
collaboration  product  candidates  could  be  unsuccessful,  which  would  delay  or  preclude  regulatory  approval  and  commercialization  of  the 
product candidates. In the U.S. and other jurisdictions, regulatory approval can be delayed, limited or not granted for many reasons, including, 
among others:  

•  

•  

•  
•  
•  

•  

•  

•  

•  

•  

•  

•  

clinical results may not meet prescribed endpoints for the studies or otherwise provide sufficient data to support the efficacy of our 
product candidates;  
clinical and nonclinical test results may reveal side effects, adverse events or unexpected safety issues associated with the use of 
our product candidates; for example, in April 2014, a clinical hold was placed on patient enrollment and dosing of PEGPH20 in 
Study  202  as  a  result  of  a  possible  difference  in  the  thromboembolic  event  rate  that  had  been  observed  at  that  time  in  the  trial 
between the group of patients treated with PEGPH20 versus the group of patients treated without PEGPH20. The clinical hold was 
lifted  by  FDA  in  June  2014,  and  we  have  resumed  enrollment  and  dosing  of  PEGPH20  in  Study  202  under  a  revised  clinical 
protocol;  
regulatory review may not find a product candidate safe or effective enough to merit either continued testing or final approval; 
regulatory review may not find that the data from preclinical testing and clinical trials justifies approval; 
regulatory authorities may require that we change our studies or conduct additional studies which may significantly delay or make 
continued pursuit of approval commercially unattractive; for example, we are currently in dialog but do not have clarity from the 
FDA regarding the data that we will need for a label change for Hylenex recombinant to be used in CSII;  
a  regulatory  agency  may  reject  our  trial  data  or  disagree  with  our  interpretations  of  either  clinical  trial  data  or  applicable 
regulations;  
a  regulatory  agency  may  approve  only  a  narrow  use  of  our  product  or  may  require  additional  safety  monitoring  and  reporting 
through Risk Evaluation and Mitigation Strategies (REMS) or conditions to assure safe use program;  
the cost of clinical trials required for product approval may be greater than what we originally anticipate, and we may decide to not 
pursue regulatory approval for such a product;  
a regulatory agency may not approve our manufacturing processes or facilities, or the processes or facilities of our collaborators, 
our contract manufacturers or our raw material suppliers;  
a  regulatory  agency  may  identify  problems  or  other  deficiencies  in  our  existing  manufacturing  processes  or  facilities,  or  the 
existing processes or facilities of our collaborators, our contract manufacturers or our raw material suppliers;  
a regulatory agency may change its formal or informal approval requirements and policies, act contrary to previous guidance, adopt 
new regulations or raise new issues or concerns late in the approval process; or  
a  product  candidate  may  be  approved  only  for  indications  that  are  narrow  or  under  conditions  that  place  the  product  at  a 
competitive  disadvantage,  which  may  limit  the  sales  and  marketing  activities  for  such  product  candidate  or  otherwise  adversely 
impact the commercial potential of a product.  

If a proprietary or collaboration product candidate is not approved in a timely fashion on commercially viable terms, or if development of 
any product candidate is terminated due to difficulties or delays encountered in the regulatory approval process, it could have a material adverse 
impact  on  our  business,  and  we  would  become  more  dependent  on  the  development  of  other  proprietary  or  collaboration  product  candidates 
and/or  our  ability  to  successfully  acquire  other  products  and  technologies.  There  can  be  no  assurances  that  any  proprietary  or  collaboration 
product candidate will receive regulatory approval in a timely manner, or at all. For example, we are in dialog but have not reached agreement 
with the FDA regarding the requirements for updating the Hylenex recombinant label for use in CSII. There can be no assurance that we will be 
able to gain clarity as to the FDA’s requirements or that the requirements may be satisfied in a commercially feasible way, in which case our 
ability to enter into collaborations with third parties or explore other strategic alternatives to exploit this opportunity will be limited or may not 
be possible.  

16  

 
 
 
 
We anticipate  that  certain proprietary  and collaboration products  will  be marketed, and perhaps  manufactured,  in foreign countries.  The 
process of obtaining regulatory approvals in foreign countries is subject to delay and failure for the reasons set forth above, as well as for reasons 
that vary from jurisdiction to jurisdiction. The approval process varies among countries and jurisdictions and can involve additional testing. The 
time required to obtain approval may differ from that required to obtain FDA approval. Foreign regulatory agencies may not provide approvals 
on  a  timely  basis,  if  at  all.  Approval  by  the  FDA  does  not  ensure  approval  by  regulatory  authorities  in  other  countries  or  jurisdictions,  and 
approval by one foreign regulatory authority does not ensure approval by regulatory authorities in other foreign countries or jurisdictions or by 
the FDA.  

Our third party collaborators are responsible for providing certain proprietary materials that are essential components of our collaboration 
products and product candidates, and any failure to supply these materials could delay the development and commercialization efforts for 
these collaboration products and product candidates and/or damage our collaborations.  

Our  development  and  commercialization  collaborators  are  responsible  for  providing  certain  proprietary  materials  that  are  essential 
components of our collaboration products and product candidates. For example, Roche is responsible for producing the Herceptin and MabThera 
required  for  its  subcutaneous  products  and  Baxter  is  responsible  for  producing  the  GAMMAGARD  LIQUID  for  its  product  HYQVIA.  If  a 
collaborator, or any applicable third party service provider of a collaborator, encounters difficulties in the manufacture, storage, delivery, fill, 
finish or packaging of the collaboration product or product candidate or component of such product or product candidate, such difficulties could 
(i) cause the delay of clinical trials or otherwise delay or prevent the regulatory approval of collaboration product candidates; and/or (ii) delay or 
prevent the effective commercialization of collaboration products. Such delays could have a material adverse effect on our business and financial 
condition.  

We rely on third parties to prepare, fill, finish and package our products and product candidates, and if such third parties should fail to 
perform, our commercialization and development efforts for our products and product candidates could be delayed or stopped.  

We rely on third parties to store and ship bulk rHuPH20 on our behalf and to also prepare, fill, finish and package our products and product 
candidates prior to their distribution. If we are unable to locate third parties to perform these functions on terms that are acceptable to us, or if the 
third  parties  we  identify  fail  to  perform  their  obligations,  the  progress  of  clinical  trials  could  be  delayed  or  even  suspended  and  the 
commercialization  of  approved  product  candidates  could  be  delayed  or  prevented. In  addition,  we  are  in  the  early  stages  of  scaling  up  our 
manufacturing of PEGPH20 with a third party to support additional clinical trials, including a possible registration-enabling trial, and ultimately, 
if approved, potential commercial supply. If our contract manufacturer is unable to successfully manufacture and supply PEGPH20, the progress 
of our clinical trials could be delayed or halted for a period of time.  

If we are unable to sufficiently develop our sales, marketing and distribution capabilities or enter into successful agreements with third 
parties to perform these functions, we will not be able to fully commercialize our products.  

We may not be successful in marketing and promoting our approved product, Hylenex recombinant, or any other products we develop or 
acquire in the future. Our sales, marketing and distribution capabilities are very limited. In order to commercialize any products successfully, we 
must  internally  develop  substantial  sales,  marketing  and  distribution  capabilities  or  establish  collaborations  or  other  arrangements  with  third 
parties to perform these services. We do not have extensive experience in these areas, and we may not be able to establish adequate in-house 
sales,  marketing  and  distribution  capabilities  or  engage  and  effectively  manage  relationships  with  third  parties  to  perform  any  or  all  of  such 
services. To the extent that we enter into co-promotion or other licensing arrangements, our product revenues are likely to be lower than if we 
directly marketed and sold our products, and any revenues we receive will depend upon the efforts of third parties, whose efforts may not meet 
our expectations or be successful. These third parties would be largely responsible for the speed and scope of sales and marketing efforts, and 
may not dedicate the resources necessary to maximize product opportunities. Our ability to cause these third parties to increase the speed and 
scope of their efforts may also be limited. In addition, sales and marketing efforts could be negatively impacted by the delay or failure to obtain 
additional supportive clinical trial data for our products. In some cases, third party collaborators are responsible for conducting these additional 
clinical trials, and our ability to increase the efforts and resources allocated to these trials may be limited. For example, in January 2011, we and 
Baxter mutually agreed to terminate the collaboration agreement for the marketing rights of Hylenex recombinant and the associated agreements.

If  we  or  our  collaborators  fail  to  comply  with  regulatory  requirements  applicable  to  promotion,  sale  and  manufacturing  of  approved 
products, regulatory agencies may take action against us or them, which could significantly harm our business.  

Any  approved  products,  along  with  the  manufacturing  processes,  post-approval  clinical  data,  labeling,  advertising  and  promotional 
activities  for  these  products,  are  subject  to  continual  requirements  and  review  by  the  FDA,  state  and  foreign  regulatory  bodies.  Regulatory 
authorities subject a marketed product, its manufacturer and the manufacturing facilities to continual review and periodic inspections. We, our 
collaborators  and  our  respective  contractors,  suppliers  and  vendors,  will  be  subject  to  ongoing  regulatory  requirements,  including  complying 
with  regulations  and  laws  regarding  advertising,  promotion  and  sales  of  drug  products,  required  submissions  of  safety  and  other  post-market 
information and reports, registration requirements, cGMP regulations (including requirements relating to quality control and quality assurance, 
as  well  as  the  corresponding  maintenance  of  records  and  documentation),  and  the  requirements  regarding  the  distribution  of  samples  to 
physicians and recordkeeping requirements. Regulatory agencies may change existing requirements or adopt new requirements or policies. We, 
our collaborators and our respective contractors, suppliers and vendors, may be slow to adapt or may not be able to adapt to these changes or 
new requirements.  

In particular, regulatory requirements applicable to pharmaceutical  products make  the  substitution of  suppliers and manufacturers costly 
and time consuming. We have minimal internal manufacturing capabilities and are, and expect to be in the future, entirely dependent on contract 
manufacturers  and  suppliers  for  the  manufacture  of  our  products  and  for  their  active  and  other  ingredients.  The  disqualification  of  these 
manufacturers  and  suppliers  through  their  failure  to  comply  with  regulatory  requirements  could  negatively  impact  our  business  because  the 
delays and costs in obtaining and qualifying alternate suppliers (if such alternative suppliers are available, which we cannot assure) could delay 
clinical trials or otherwise inhibit our ability to bring approved products to market, which would have a material adverse effect on our business 
and financial condition. Likewise, if we, our collaborators and our respective contractors, suppliers and vendors involved in sales and promotion 
of our products do not comply with applicable laws and regulations, for example off-label or false or misleading promotion, this could materially 
harm our business and financial condition.  

Failure to comply with regulatory requirements may result in any of the following:  

restrictions on our products or manufacturing processes; 

•  
•   warning letters; 
•   withdrawal of the products from the market; 
•   voluntary or mandatory recall; 
•  
•  
•  
•  
•  
•   product seizure; 
•  
•  

injunctions; or 
imposition of civil or criminal penalties. 

fines; 
suspension or withdrawal of regulatory approvals; 
suspension or termination of any of our ongoing clinical trials; 
refusal to permit the import or export of our products; 
refusal to approve pending applications or supplements to approved applications that we submit; 

We may wish to raise additional capital in the future and there can be no assurance that we will be able to obtain such funds.  

We may wish to raise additional capital in the future to continue the development of our product candidates or for other current corporate 
purposes. Our current cash reserves and expected revenues during the next few years may not be sufficient for us to continue the development of 
our  proprietary  product  candidates,  to  fund  general  operations  and  conduct  our  business  at  the  level  desired.  In  addition,  if  we  engage  in 
acquisitions of companies, products or technologies in order to execute our business strategy, we may need to raise additional capital. We may 
raise  additional  capital  in  the  future  through  one  or  more  financing  vehicles  that  may  be  available  to  us  including  (i)  the  public  or  private 
issuance of securities; (ii) new collaborative agreements; and/or (iii) expansions or revisions to existing collaborative relationships.  

In  view  of  our  stage  of  development,  business  prospects,  the  nature  of  our  capital  structure  and  general  market  conditions,  if  we  are 
required to raise additional capital in the future, the additional financing may not be available on favorable terms, or at all. If additional capital is 
not available on favorable terms when needed, we will be required to raise capital on adverse terms or  

18  

 
 
 
 
significantly  reduce  operating  expenses  through  the  restructuring  of  our  operations.  If  we  raise  additional  capital,  a  substantial  number  of 
additional shares may be issued, and these shares will dilute the ownership interest of our current investors.  

We  currently  have  significant  debt  and  failure  by  us  to  fulfill  our  obligations  under  the  applicable  loan  agreements  may  cause  the 
repayment obligations to accelerate.  

In December 2013, we entered into an Amended and Restated Loan and Security Agreement (the Loan Agreement) with Oxford Finance 
LLC (Oxford) and Silicon Valley Bank (SVB) (collectively, the Lenders), amending and restating in its entirety our original loan agreement with 
the Lenders, dated December 2012. The Loan Agreement provided for an additional $20 million principal amount of new term loan, bringing the 
total term loan balance to $50 million. The proceeds are to be used for working capital and general business requirements. In January 2015, we 
entered into the Second Amendment to the Amended and Restated Loan and Security Agreement and First Amendment to Disbursement Letter 
(the  “Amendment”)  with  the  Lenders,  amending  and  restating  the  loan  payment  schedules  of  the  Amended  and  Restated  Loan  and  Security 
Agreement. The amended and  restated term loan repayment schedule provides for  interest only payments through January 2016,  followed by 
consecutive  equal  monthly  payments  of  principal  and  interest  in  arrears  starting  in  February  2016  and  continuing  through  the  previously 
established  maturity  date  of  January  2018.  The  amended  and  restated  term  loan  facility  is  secured  by  substantially  all  of  the  assets  of  the 
Company and its subsidiary, Halozyme, Inc., except that the collateral does not include any equity interests in Halozyme, Inc., any intellectual 
property (including all licensing, collaboration and similar agreements relating thereto), and certain other excluded assets. The Loan Agreement 
contains customary representations, warranties and covenants by us, which covenants limit our ability to convey, sell, lease, transfer, assign or 
otherwise  dispose of certain of our assets; engage  in any business other  than  the businesses  currently  engaged in  by  us or reasonably  related 
thereto; liquidate or dissolve; make certain management changes; undergo certain change of control events; create, incur, assume, or be liable 
with respect to certain indebtedness; grant certain liens; pay dividends and make certain other restricted payments; make certain investments; 
make  payments  on  any subordinated  debt;  and  enter  into  transactions  with  any  of  our  affiliates  outside  of  the  ordinary  course  of  business  or 
permit our subsidiaries  to do  the  same.  In  addition, subject  to  certain  exceptions,  we  are  required  to  maintain  with  SVB  our  primary  deposit 
accounts, securities accounts and commodities, and to do the same for our domestic subsidiary. Complying with these covenants may make it 
more difficult for us to successfully execute our business strategy.  

The Loan Agreement also contains customary indemnification obligations and customary events of default, including, among other things, 
our failure to fulfill certain of our obligations under the Loan Agreement and the occurrence of a material adverse change which is defined as a 
material adverse change in our business, operations or condition (financial or otherwise), a material impairment of the prospect of repayment of 
any portion of the loan, or a material impairment in the perfection or priority of lender’s lien in the collateral or in the value of such collateral. In 
the event of default by us under the Loan Agreement, the Lenders would be entitled to exercise their remedies thereunder, including the right to 
accelerate the debt, upon which we may be required to repay all amounts then outstanding under the Loan Agreement which could harm our 
financial condition.  

If proprietary or collaboration product candidates are approved for marketing but do not gain market acceptance, our business may suffer 
and we may not be able to fund future operations.  

Assuming that our proprietary or collaboration product candidates obtain the necessary regulatory approvals for commercial sale, a number 
of factors may affect the market acceptance of these existing product candidates or any other products which are developed or acquired in the 
future, including, among others:  

•  
•  

the price of products relative to other therapies for the same or similar treatments; 
the  perception  by  patients,  physicians  and  other  members  of  the  health  care  community  of  the  effectiveness  and  safety  of  these 
products for their prescribed treatments relative to other therapies for the same or similar treatments;  

•   our ability to fund our sales and marketing efforts and the ability and willingness of our collaborators to fund sales and marketing 

•  
•  
•  
•  

efforts;  
the degree to which the use of these products is restricted by the approved product label; 
the effectiveness of our sales and marketing efforts and the effectiveness of the sales and marketing efforts of our collaborators; 
the introduction of generic competitors; and 
the  extent  to  which  reimbursement  for  our  products  and  related  treatments  will  be  available  from  third  party  payors  including 
government insurance programs (Medicare and Medicaid) and private insurers.  

19  

 
 
 
 
If these products do not gain market acceptance, we may not be able to fund future operations, including the development or acquisition of 

new product candidates and/or our sales and marketing efforts for our approved products, which would cause our business to suffer.  

In addition, our proprietary and collaboration product candidates will be restricted to the labels approved by FDA and applicable regulatory 
bodies, and these restrictions may limit the marketing and promotion of the ultimate products. If the approved labels are restrictive, the sales and 
marketing efforts for these products may be negatively affected.  

Developing and marketing pharmaceutical products for human use involves significant product liability risks for which we currently have 
limited insurance coverage.  

The  testing,  marketing  and  sale  of  pharmaceutical  products  involves  the  risk  of  product  liability  claims  by  consumers  and  other  third 
parties. Although we maintain product liability insurance coverage, product liability claims can be high in the pharmaceutical industry, and our 
insurance may not sufficiently cover our actual liabilities. If product liability claims were to be made against us, it is possible that the liabilities 
may exceed the limits of our insurance policy, or our insurance carriers may deny, or attempt to deny, coverage in certain instances. If a lawsuit 
against us  is successful, then the lack or insufficiency of insurance coverage could  materially  and adversely  affect our business and financial 
condition. Furthermore, various distributors of pharmaceutical products require minimum product liability insurance coverage before purchase or 
acceptance of products for distribution. Failure to satisfy these insurance requirements could impede our ability to achieve broad distribution of 
our  proposed  products,  and  higher  insurance  requirements  could  impose  additional  costs  on  us.  In  addition,  since  many  of  our  collaboration 
product  candidates  include  the  pharmaceutical  products  of  a  third  party,  we  run  the  risk  that  problems  with  the  third  party  pharmaceutical 
product will give rise to liability claims against us.  

Our inability to attract, hire and retain key management and scientific personnel could negatively affect our business.  

Our success depends on the performance of key management and scientific employees with relevant experience. For example, in order to 
pursue our current business strategy, we will need to recruit and retain personnel experienced in oncology drug development which is a highly 
competitive market for talent. We depend substantially on our ability to hire, train, motivate and retain high quality personnel, especially our 
scientists and management team. Particularly in view of the small number of employees on our staff to cover our numerous programs and key 
functions,  if  we  are  unable  to  retain  existing  personnel  or  identify  or  hire  additional  personnel,  we  may  not  be  able  to  research,  develop, 
commercialize or market our products and product candidates as expected or on a timely basis and we may not be able to adequately support 
current and future alliances with strategic collaborators.  

Furthermore, if we were to lose key management personnel, we would likely lose some portion of our institutional knowledge and technical 
know-how, potentially causing a substantial delay in one or more of our development programs until adequate replacement personnel could be 
hired  and  trained.  We  currently  have  a  severance  policy  applicable  to  all  employees  and  a  change  in  control  policy  applicable  to  senior 
executives.  Other  than  for  vesting  provisions  in  equity  based  awards,  we  have  not  adopted  any  other  policies  or  entered  into  any  other 
agreements specifically designed to motivate officers or other employees to remain with us.  

We do not have key man life insurance policies on the lives of any of our employees.  

Our operations might be interrupted by the occurrence of a natural disaster or other catastrophic event.  

Our  operations,  including  laboratories,  offices  and  other  research  facilities,  are  located  in  four  buildings  in  San  Diego,  California.  We 
depend on our facilities and on our collaborators, contractors and vendors for the continued operation of our business. Natural disasters or other 
catastrophic  events,  interruptions  in  the  supply  of  natural  resources,  political  and  governmental  changes,  wildfires  and  other  fires,  floods, 
explosions, actions of animal rights activists, earthquakes and civil unrest could disrupt our operations or those of our collaborators, contractors 
and vendors. Even though we believe we carry commercially reasonable business interruption and liability insurance, and our contractors may 
carry  liability  insurance  that  protect  us  in  certain  events,  we  may  suffer  losses  as  a  result  of  business  interruptions  that  exceed  the  coverage 
available  under  our  and  our  contractors'  insurance  policies  or  for  which  we  or  our  contractors  do  not  have  coverage.  Any  natural  disaster  or 
catastrophic event could have a significant negative impact on our operations and financial results. Moreover, any such event could delay our 
research and development programs.  

20  

 
 
 
 
If we or our collaborators do not achieve projected development, clinical, regulatory or sales goals in the timeframes we publicly announce 
or otherwise expect, the commercialization of our products and the development of our product candidates may be delayed and, as a result, 
our stock price may decline, and we may face lawsuits relating to such declines.  

From  time  to  time,  we  or  our  collaborators  may  publicly  articulate  the  estimated  timing  for  the  accomplishment  of  certain  scientific, 
clinical, regulatory and other product development goals. The accomplishment of any goal is typically based on numerous assumptions, and the 
achievement  of  a  particular  goal  may  be  delayed  for  any  number  of  reasons  both  within  and  outside  of  our  control.  If  scientific,  regulatory, 
strategic or other factors cause us to not meet a goal, regardless of whether that goal has been publicly articulated or not, our stock price may 
decline rapidly. For example, the announcement in April 2014 of the temporary halting of our Phase 2 clinical trial for PEGPH20 caused a rapid 
decline in our stock price. Stock price declines may also trigger direct or derivative shareholder lawsuits. As with any litigation proceeding, the 
eventual outcome of any legal action is difficult to predict. If any such lawsuits occur, we will incur expenses in connection with the defense of 
these lawsuits, and we may have to pay substantial damages or settlement costs in connection with any resolution thereof. Although we have 
insurance coverage against which we may claim recovery against some of these expenses and costs, the amount of coverage may not be adequate 
to cover the full amount or certain expenses and costs may be outside the scope of the policies we maintain. In the event of an adverse outcome 
or  outcomes, our business  could  be  materially  harmed  from  depletion  of  cash  resources,  negative  impact  on  our  reputation,  or  restrictions  or 
changes to our governance or other processes that may result from any final disposition of the lawsuit. Moreover, responding to and defending 
pending litigation significantly diverts management's attention from our operations.  

In addition, the consistent failure to meet publicly announced milestones may erode the credibility of our management team with respect to 

future milestone estimates.  

Future acquisitions could disrupt our business and harm our financial condition.  

In order to augment our product pipeline or otherwise strengthen our business, we may decide to acquire additional businesses, products 
and  technologies.  As  we  have  limited  experience  in  evaluating  and  completing  acquisitions,  our  ability  as  an  organization  to  make  such 
acquisitions is unproven. Acquisitions could require significant capital infusions and could involve many risks, including, but not limited to, the 
following:  

•   we  may have  to issue  convertible  debt  or  equity  securities  to  complete  an  acquisition,  which  would  dilute  our  stockholders  and 

•  

could adversely affect the market price of our common stock;  
an acquisition may negatively impact our results of operations because it may require us to amortize or write down amounts related 
to goodwill and other intangible assets, or incur or assume substantial debt or liabilities, or it may cause adverse tax consequences, 
substantial depreciation or deferred compensation charges;  

•   we  may  encounter  difficulties  in  assimilating  and  integrating  the  business,  products,  technologies,  personnel  or  operations  of 

•  

•  

companies that we acquire;  
certain  acquisitions  may  impact  our  relationship  with  existing  or  potential  collaborators  who  are  competitive  with  the  acquired 
business, products or technologies;  
acquisitions  may  require  significant  capital  infusions  and  the  acquired  businesses,  products  or  technologies  may  not  generate 
sufficient value to justify acquisition costs;  

•   we may take on liabilities from the acquired company such as debt, legal liabilities or business risk which could be significant; 
•  
•  
•   key personnel of an acquired company may decide not to work for us. 

an acquisition may disrupt our ongoing business, divert resources, increase our expenses and distract our management; 
acquisitions may involve the entry into a geographic or business market in which we have little or no prior experience; and 

If any of these risks occurred, it could adversely affect our business, financial condition and operating results. There is no assurance that we 
will be able to identify or consummate any future acquisitions on acceptable terms, or at all. If we do pursue any acquisitions, it is possible that 
we may not realize the anticipated benefits from such acquisitions or that the market will not view such acquisitions positively.  

21  

 
 
 
 
Security breaches may disrupt our operations and harm our operating results.  

The wrongful use, theft, deliberate sabotage or any other type of security breach with respect to any of our information technology storage 
and  access  systems  could  result  in  disclosure  or  dissemination  of  our  proprietary  and  confidential  information  that  is  electronically  stored, 
including research or clinical data, resulting in a material adverse impact on our business, operating results and financial condition. Our security 
and  data  recovery  measures  may  not  be  adequate  to  protect  against  computer  viruses,  break-ins,  and  similar  disruptions  from  unauthorized 
tampering  with  our  electronic  storage  systems.  Furthermore,  any  physical  break-in  or  trespass  of  our  facilities  could  result  in  the 
misappropriation,  theft,  sabotage  or  any  other  type  of  security  breach  with  respect  to  our  proprietary  and  confidential  information,  including 
research  or  clinical  data  or  damage  to  our  research  and  development  equipment  and  assets.  Such  adverse  effects  could  be  material  and 
irrevocable to our business, operating results and financial condition.  

Risks Related To Ownership of Our Common Stock  

Our stock price is subject to significant volatility.  

We participate in a highly dynamic industry which often results in significant volatility in the market price of common stock irrespective of 
company performance. As a result, our high and low sales prices of our common stock during the twelve months ended December 31, 2014 were 
$18.18 and $6.88 , respectively. We expect our stock price to continue to be subject to significant volatility and, in addition to the other risks and 
uncertainties described elsewhere in this Annual Report on Form 10-K and all other risks and uncertainties that are either not known to us at this 
time or which we deem to be immaterial, any of the following factors may lead to a significant drop in our stock price:  

•  
•  

•  

•  
•  

•  
•  
•  
•  

the presence of competitive products to those being developed by us; 
failure  (actual  or  perceived)  of  our  collaborators  to  devote  attention  or  resources  to  the  development  or  commercialization  of 
product candidates licensed to such collaborator;  
a dispute regarding our failure, or the failure of one of our third party collaborators, to comply with the terms of a collaboration 
agreement;  
the termination, for any reason, of any of our collaboration agreements; 
the  sale  of  common  stock  by  any  significant  stockholder,  including,  but  not  limited  to,  direct  or  indirect  sales  by  members  of 
management or our Board of Directors;  
the resignation, or other departure, of members of management or our Board of Directors; 

•  
•   general negative conditions in the healthcare industry; 
•   general negative conditions in the financial markets; 
•  
•  
•  

the failure, for any reason, to obtain regulatory approval for any of our proprietary or collaboration product candidates; 
the failure, for any reason, to secure or defend our intellectual property position; 
for those products that are not yet approved for commercial sale, the failure or delay of applicable regulatory bodies to approve 
such products;  
identification of safety or tolerability issues; 
failure of clinical trials to meet efficacy endpoints; 
suspensions or delays in the conduct of clinical trials or securing of regulatory approvals; 
adverse  regulatory  action  with  respect  to  our  and  our  collaborators’  products  and  product  candidates  such  as  clinical  holds, 
imposition of onerous requirements for approval or product recalls;  

•   our failure, or the failure of our third party collaborators, to successfully commercialize products approved by applicable regulatory 

bodies such as the FDA;  

•   our failure, or the failure of our third party collaborators, to generate product revenues anticipated by investors; 
•   problems with a bulk rHuPH20 contract manufacturer or a fill and finish manufacturer for any product or product candidate; 
•  
•   our failure to obtain financing on acceptable terms; or 
•  

the sale of additional debt and/or equity securities by us; 

a restructuring of our operations. 

22  

 
 
 
 
Future transactions where we raise capital may negatively affect our stock price.  

We  are  currently  a  “Well-Known  Seasoned  Issuer”  and  may  file  automatic  shelf  registration  statements  at  any  time  with  the  SEC.  In 
addition,  we  currently  have  the  ability  to  offer  and  sell  additional  equity,  debt  securities  and  warrants  to  purchase  such  securities,  either 
individually or in units, under an effective automatic shelf registration statement. Sales of substantial amounts of shares of our common stock or 
other securities under our shelf registration statements could lower the market price of our common stock and impair our ability to raise capital 
through the sale of equity securities. In the future, we may issue additional options, warrants or other derivative securities convertible into our 
common stock.  

Our  rights  agreement  and  anti-takeover  provisions  in  our  charter  documents  and  Delaware  law  may  make  an  acquisition  of  us  more 
difficult.  

We are party to a Rights Agreement designed to deter abusive takeover tactics and to encourage prospective acquirers to negotiate with our 
board of directors rather than attempt to acquire us in a manner or on terms that our board deems unacceptable, which could delay or discourage 
takeover attempts that stockholders may consider favorable.  

In addition, anti-takeover provisions in our charter documents and Delaware law may make an acquisition of us more difficult. First, our 
board  of  directors  is  classified  into three  classes  of  directors. Under Delaware law, directors  of  a  corporation  with  a classified  board may  be 
removed  only  for  cause  unless  the  corporation's  certificate  of  incorporation  provides  otherwise.  Our  amended  and  restated  certificate  of 
incorporation, as amended, does not provide otherwise. In addition, our bylaws limit who may call special meetings of stockholders, permitting 
only stockholders holding at least 50% of our outstanding shares to call a special meeting of stockholders. Our amended and restated certificate 
of incorporation, as amended, does not include a provision for cumulative voting for directors. Under cumulative voting, a minority stockholder 
holding a sufficient percentage of a class of shares may be able to ensure the election of one or more directors. Finally, our bylaws establish 
procedures, including advance notice procedures, with regard to the nomination of candidates for election as directors and stockholder proposals. 

These provisions may discourage potential takeover attempts, discourage bids for our common stock at a premium over market price or 
adversely affect the market price of, and the voting and other rights of the holders of, our common stock. These provisions could also discourage 
proxy contests and make it more difficult for stockholders to elect directors other than the candidates nominated by our board of directors.  

In  addition,  because  we  are  incorporated  in  Delaware,  we  are  governed  by  the  provisions  of  Section  203  of  the  Delaware  General 

Corporation Law, which may prohibit large stockholders from consummating a merger with, or acquisition of, us.  

These provisions may deter an acquisition of us that might otherwise be attractive to stockholders.  

Risks Related to Our Industry  

Our  products  must  receive  regulatory  approval  before  they  can  be  sold,  and  compliance  with  the  extensive  government  regulations  is 
expensive and time consuming and may result in the delay or cancellation of product sales, introductions or modifications.  

Extensive  industry  regulation  has  had,  and  will  continue  to  have,  a  significant  impact  on  our  business.  All  pharmaceutical  companies, 
including ours, are subject to extensive, complex, costly and evolving regulation by the health regulatory agencies including the FDA (and with 
respect to controlled drug substances, the U.S. Drug Enforcement Administration (DEA)) and equivalent foreign regulatory agencies and state 
and  local/regional  government  agencies.  The  Federal  Food,  Drug  and  Cosmetic  Act,  the  Controlled  Substances  Act  and  other  domestic  and 
foreign  statutes  and  regulations  govern  or  influence  the  testing,  manufacturing,  packaging,  labeling,  storing,  recordkeeping,  safety,  approval, 
advertising, promotion, sale and distribution of our products. We are dependent on receiving FDA and other governmental approvals prior to 
manufacturing,  marketing  and  shipping  our  products.  Consequently,  there  is  always  a  risk  that  the  FDA  or  other  applicable  governmental 
authorities will not approve our products or may impose onerous, costly and time-consuming requirements such as additional clinical or animal 
testing.  Regulatory  authorities  may  require  that  we  change  our  studies  or  conduct  additional  studies,  which  may  significantly  delay  or  make 
continued pursuit of approval commercially unattractive. We are currently in dialog but do not have clarity from the FDA regarding the path for 
a labeling update to include key efficacy and safety data prior to initiating Hylenex recombinant for use in CSII. There can be no assurance that 
we will be able to gain clarity as to the FDA's requirements. The FDA or other foreign regulatory agency may,  

23  

 
 
 
 
at any time, halt our and our collaborators' development and commercialization activities due to safety concerns. In addition, even if our products 
are  approved,  regulatory  agencies  may  also  take  post-approval  action  limiting  or  revoking  our  ability  to  sell  our  products.  Any  of  these 
regulatory actions may adversely affect the economic benefit we may derive from our products and therefore harm our financial condition.  

Under  certain  of  these  regulations,  we  and  our  contract  suppliers  and  manufacturers  are  subject  to  periodic  inspection  of  our  or  their 
respective facilities, procedures and operations and/or the testing of products by the FDA, the DEA and other authorities, which conduct periodic 
inspections to confirm that we and our contract suppliers and manufacturers are in compliance with all applicable regulations. The FDA also 
conducts  pre-approval  and  post-approval  reviews  and  plant  inspections  to  determine  whether  our  systems,  or  our  contract  suppliers'  and 
manufacturers' processes, are in compliance with cGMP and other FDA regulations. If we, or our contract supplier, fail these inspections, we 
may not be able to commercialize our product in a timely manner without incurring significant additional costs, or at all.  

In  addition,  the  FDA  imposes  a  number  of  complex  regulatory  requirements  on  entities  that  advertise  and  promote  pharmaceuticals 
including, but not limited to, standards and regulations for direct-to-consumer advertising, off-label promotion, industry-sponsored scientific and 
educational activities, and promotional activities involving the internet.  

We may be subject, directly or indirectly, to various broad federal and state healthcare laws. If we are unable to comply, or have not fully 
complied,  with  such  laws,  we  could  face  civil,  criminal  and  administrative  penalties,  damages,  monetary  fines,  disgorgement,  possible 
exclusion  from  participation  in  Medicare,  Medicaid  and  other  federal  healthcare  programs,  contractual  damages,  reputational  harm, 
diminished profits and future earnings and curtailment or restructuring of our operations, any of which could adversely affect our ability 
to operate.  

Our business operations and activities may be directly, or indirectly, subject to various broad federal and state healthcare laws, including 
without limitation, anti-kickback laws, false claims laws, civil monetary penalty laws, data privacy and security laws, tracing and tracking laws, 
as well as transparency laws regarding payments or other items of value provided to healthcare providers. These laws may restrict or prohibit a 
wide  range  of  business  activities,  including,  but  not  limited  to,  research,  manufacturing,  distribution,  pricing,  discounting,  marketing  and 
promotion and other business arrangements. These laws may impact, among other things, our current activities with principal investigators and 
research subjects, as well as sales, marketing and education programs. Many states have similar healthcare fraud and abuse laws, some of which 
may be broader in scope and may not be limited to items or services for which payment is made by a government health care program.  

Efforts to ensure that our business arrangements will comply with applicable healthcare laws may involve substantial costs. While we have 
adopted a healthcare corporate compliance program, it is possible that governmental and enforcement authorities will conclude that our business 
practices may not comply with current or future statutes, regulations or case law interpreting applicable fraud and abuse or other healthcare laws. 
If our operations or activities are found to be in violation of any of the laws described above or any other governmental regulations that apply to 
us,  we  may  be  subject  to,  without  limitation,  civil,  criminal  and  administrative  penalties,  damages,  monetary  fines,  disgorgement,  possible 
exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished 
profits and future earnings and curtailment or restructuring of our operations, any of which could adversely affect our ability to operate.  

In addition, any sales of products outside the U.S. will also likely subject us to foreign equivalents of the healthcare laws mentioned above, 

among other foreign laws.  

We may be required to initiate or defend against legal proceedings related to intellectual property rights, which may result in substantial 
expense, delay and/or cessation of the development and commercialization of our products.  

We primarily rely on patents to protect our intellectual property rights. The strength of this protection, however, is uncertain. For example, 

it is not certain that:  

•   we will be able to obtain patent protection for our products and technologies; 
•  

the  scope  of  any  of  our  issued  patents  will  be  sufficient  to  provide  commercially  significant  exclusivity  for  our  products  and 
technologies;  

•   others will not independently develop similar or alternative technologies or duplicate our technologies and obtain patent protection 

before we do; and  

24  

 
 
 
 
•  

any of our issued patents, or patent pending applications that result in issued patents, will be held valid, enforceable and infringed 
in the event the patents are asserted against others.  

We  currently  own  or  license  several  patents  and  also  have  pending  patent  applications  applicable  to  rHuPH20  and  other  proprietary 
materials. There can  be no assurance that our existing patents, or any patents  issued to us as a result of  our pending patent applications, will 
provide a basis for commercially viable products, will provide us with any competitive advantages, or will not face third party challenges or be 
the  subject  of  further  proceedings  limiting  their  scope  or  enforceability.  Any  weaknesses  or  limitations  in  our  patent  portfolio  could  have  a 
material  adverse  effect  on  our  business  and  financial  condition.  In  addition,  if  any  of  our  pending  patent  applications  do  not  result  in  issued 
patents,  or  result  in  issued  patents  with  narrow  or  limited  claims,  this  could  result  in  us  having  no  or  limited  protection  against  generic  or 
biosimilar competition against our product candidates which would have a material adverse effect on our business and financial condition.  

We may become involved in interference proceedings in the U.S. Patent and Trademark Office, or other proceedings in other jurisdictions, 

to determine the priority, validity or enforceability of our patents. In addition, costly litigation could be necessary to protect our patent position.  

We  also  rely  on  trademarks  to  protect  the  names  of  our  products  (e.g.  Hylenex  recombinant).  We  may  not  be  able  to  obtain  trademark 
protection  for  any  proposed  product  names  we  select.  In  addition,  product  names  for  pharmaceutical  products  must  be  approved  by  health 
regulatory  authorities  such  as  the  FDA  in  addition  to  meeting  the  legal  standards  required  for  trademark  protection  and  product  names  we 
propose may not be timely approved by regulatory agencies which may delay product launch. In addition, our trademarks may be challenged by 
others. If we enforce our trademarks against third parties, such enforcement proceedings may be expensive.  

We  also  rely  on  trade  secrets,  unpatented  proprietary  know-how  and  continuing  technological  innovation  that  we  seek  to  protect  with 
confidentiality  agreements  with  employees,  consultants  and  others  with  whom  we  discuss  our  business.  Disputes  may  arise  concerning  the 
ownership of intellectual property or the applicability or enforceability of these agreements, and we might not be able to resolve these disputes in 
our favor.  

In addition to protecting our own intellectual property rights, third parties may assert patent, trademark or copyright infringement or other 
intellectual  property  claims  against  us.  If  we  become  involved  in  any  intellectual  property  litigation,  we  may  be  required  to  pay  substantial 
damages,  including  but  not  limited  to  treble  damages,  attorneys'  fees  and  costs,  for  past  infringement  if  it  is  ultimately  determined  that  our 
products infringe a third party's intellectual property rights. Even if infringement claims against us are without merit, defending a lawsuit takes 
significant  time,  may  be  expensive  and  may  divert  management's  attention  from  other  business  concerns.  Further,  we  may  be  stopped  from 
developing,  manufacturing  or  selling  our  products  until  we  obtain  a  license  from  the  owner  of  the  relevant  technology  or  other  intellectual 
property rights. If such a license is available at all, it may require us to pay substantial royalties or other fees.  

Patent protection for protein-based therapeutic products and other biotechnology inventions is subject to a great deal of uncertainty, and if 
patent laws or the interpretation of patent laws changes, our competitors may be able to develop and commercialize products based on our 
discoveries.  

Patent  protection  for  protein-based  therapeutic  products  is  highly  uncertain  and  involves  complex  legal  and  factual  questions.  In  recent 
years, there have been significant changes in patent law, including the legal standards that govern the scope of protein and biotechnology patents. 
Standards for patentability of full-length and partial genes, and their corresponding proteins, are changing. Recent court decisions have made it 
more  difficult  to  obtain  patents,  by  making  it  more  difficult  to  satisfy  the  patentable  subject  matter  requirement  and  the  requirement  of  non-
obviousness, have decreased the availability of injunctions against infringers, and have increased the likelihood of challenging the validity of a 
patent through a declaratory judgment action. Taken together, these decisions could make it more difficult and costly for us to obtain, license and 
enforce our patents. In addition, the Leahy-Smith America Invents Act (HR 1249) was signed into law in September 2011, which among other 
changes to the U.S. patent laws, changes patent priority from “first to invent” to “first to file,” implements a post-grant opposition system for 
patents and provides for a prior user defense to infringement. These judicial and legislative changes have introduced significant uncertainty in 
the patent law landscape and may potentially negatively impact our ability to procure, maintain and enforce patents to provide exclusivity for our 
products.  

25  

 
 
 
 
There  also  have  been,  and  continue  to  be,  policy  discussions  concerning  the  scope  of  patent  protection  awarded  to  biotechnology 
inventions. Social and political opposition to biotechnology patents may lead to narrower patent protection within the biotechnology industry. 
Social and political opposition to patents on genes and proteins and recent court decisions concerning patentability of isolated genes may lead to 
narrower patent protection, or narrower claim interpretation, for isolated genes, their corresponding proteins and inventions related to their use, 
formulation and manufacture. Patent protection relating to biotechnology products is also subject to a great deal of uncertainty outside the U.S., 
and patent laws are evolving and undergoing revision in many countries. Changes in, or different interpretations of, patent laws worldwide may 
result  in  our  inability  to  obtain  or  enforce  patents,  and  may  allow  others  to  use  our  discoveries  to  develop  and  commercialize  competitive 
products, which would impair our business.  

If third party reimbursement and customer contracts are not available, our products may not be accepted in the market.  

Our ability to earn sufficient returns on our products will depend in part on the extent to which reimbursement for our products and related 
treatments  will  be available  from  government health  administration  authorities,  private  health insurers,  managed  care organizations  and  other 
healthcare providers.  

Third-party payors are increasingly attempting to limit both the coverage and the level of reimbursement of new drug products to contain 
costs. Consequently, significant uncertainty exists as to the reimbursement status of newly approved healthcare products. Third party payors may 
not establish adequate levels of reimbursement for the products that we commercialize, which could limit their market acceptance and result in a 
material adverse effect on our financial condition.  

Customer contracts, such as with group purchasing organizations and hospital formularies, will often not offer contract or formulary status 
without either the lowest price or substantial proven clinical differentiation. If our products are compared to animal-derived hyaluronidases by 
these entities, it is possible that neither of these conditions will be met, which could limit market acceptance and result in a material adverse 
effect on our financial condition.  

The rising cost of healthcare and related pharmaceutical product pricing has led to cost containment pressures that could cause us to sell 
our products at lower prices, resulting in less revenue to us.  

Any of the proprietary or collaboration products that have been, or in the future are, approved by the FDA may be purchased or reimbursed 
by  state  and  federal  government  authorities,  private  health  insurers  and  other  organizations,  such  as  health  maintenance  organizations  and 
managed  care  organizations.  Such  third  party  payors  increasingly  challenge  pharmaceutical  product  pricing.  The  trend  toward  managed 
healthcare in the U.S., the growth of such organizations, and various legislative proposals and enactments to reform healthcare and government 
insurance programs, including the Medicare Prescription Drug Modernization Act of 2003, could significantly influence the manner in which 
pharmaceutical products are prescribed and purchased, resulting in lower prices and/or a reduction in demand. Such cost containment measures 
and healthcare reforms could adversely affect our ability to sell our products.  

In  March  2010,  the  U.S.  adopted  the  Patient  Protection  and  Affordable  Care  Act,  as  amended  by  the  Health  Care  and  Education 
Reconciliation Act (the Healthcare Reform Act). This law substantially changes the way healthcare is financed by both governmental and private 
insurers, and significantly impacts the pharmaceutical industry. The Healthcare Reform Act contains a number of provisions that are expected to 
impact  our  business  and  operations,  in  some  cases  in  ways  we  cannot  currently  predict.  Changes  that  may  affect  our  business  include  those 
governing  enrollment  in  federal  healthcare  programs,  reimbursement  changes,  fraud  and  abuse  and  enforcement.  These  changes  will  impact 
existing  government  healthcare  programs  and  will  result  in  the  development  of  new  programs,  including  Medicare  payment  for  performance 
initiatives and improvements to the physician quality reporting system and feedback program.  

Additional provisions of the Healthcare Reform Act may negatively affect our revenues in the future. For example, the Healthcare Reform 
Act imposes a non-deductible excise tax on pharmaceutical manufacturers or importers that sell branded prescription drugs to U.S. government 
programs that we believe will impact our revenues from our products. In addition, as part of the Healthcare Reform Act's provisions closing a 
funding  gap  that  currently  exists  in  the  Medicare  Part  D  prescription  drug  program,  we  will  also  be  required  to  provide  a  50%  discount  on 
branded prescription drugs dispensed to beneficiaries under this prescription drug program. We expect that the Healthcare Reform Act and other 
healthcare reform measures that may be adopted in the future could have a material adverse effect on our industry generally and on our ability to 
maintain or increase our product sales or successfully commercialize our product candidates or could limit or eliminate our future spending on 
development projects.  

26  

 
 
 
 
Furthermore, individual states have become increasingly aggressive in passing legislation and implementing regulations designed to control 
pharmaceutical  product  pricing,  including  price  or  patient  reimbursement  constraints,  discounts,  restrictions  on  certain  product  access, 
importation  from  other  countries  and  bulk  purchasing.  Legally  mandated  price  controls  on  payment  amounts  by  third  party  payors  or  other 
restrictions could negatively and materially impact our revenues and financial condition. We anticipate that we will encounter similar regulatory 
and legislative issues in most other countries outside the U.S.  

We face intense competition and rapid technological change that could result in the development of products by others that are superior to 
our proprietary and collaboration products under development.  

Our  proprietary  and  collaboration  products  have  numerous  competitors  in  the  U.S.  and  abroad  including,  among  others,  major 
pharmaceutical and  specialized biotechnology firms, universities and other research institutions  that  have developed competing products. The 
competitors for Hylenex recombinant include, but are not limited to, Valeant Pharmaceuticals International, Inc. and Amphastar Pharmaceuticals, 
Inc.  For  our  ultrafast  insulin  product  candidates,  such  competitors  may  include  Biodel  Inc.,  Eli  Lily,  Sanofi  Aventis,  Novo  Nordisk  Inc.  and 
Mannkind  Corporation.  For  our  PEGPH20  product  candidate,  such  competitors  may  include  major  pharmaceutical  and  specialized 
biotechnology firms. These competitors may develop technologies and products that are more effective, safer, or less costly than our current or 
future proprietary and collaboration product candidates or that could render our technologies and product candidates obsolete or noncompetitive. 
Many  of  these  competitors  have  substantially  more  resources  and  product  development,  manufacturing  and  marketing  experience  and 
capabilities than we do. In addition, many of our competitors have significantly greater experience than we do in undertaking preclinical testing 
and clinical trials of pharmaceutical product candidates and obtaining FDA and other regulatory approvals of products and therapies for use in 
healthcare.  

Item 1B.   Unresolved Staff Comments 

None.  

Item 2.   Properties 

Our administrative offices and research facilities are currently located in San Diego, California. We lease an aggregate of approximately 
76,000 square feet of office and research space for a monthly rent expense of approximately $145,000 , net of costs and property taxes associated 
with the operation and maintenance of the subleased facilities. We believe the current space is adequate for our immediate needs.  

Item 3.   Legal Proceedings 

From time to time, we may be involved in disputes, including litigation, relating to claims arising out of operations in the normal course of 
our business. Any of these claims could subject us to costly legal expenses and, while we generally believe that we have adequate insurance to 
cover many different types of liabilities, our insurance carriers may deny coverage or our policy limits may be inadequate to fully satisfy any 
damage awards or settlements. If this were to happen, the payment of any such awards could have a material adverse effect on our consolidated 
results of operations and financial position. Additionally, any such claims, whether or not successful, could damage our reputation and business. 
We currently are not a party to any legal proceedings, the adverse outcome of which, in management’s opinion, individually or in the aggregate, 
would have a material adverse effect on our consolidated results of operations or financial position.

Item 7.   Management’s Discussion and Analysis of Financial Condition and Results of Operation 

In  addition  to  historical  information,  the  following  discussion  contains  forward-looking  statements  that  are  subject  to  risks  and 
uncertainties. Actual results may differ substantially from those referred to herein due to a number of factors, including but not limited to risks 
described in the Part I, Item 1A, Risks Factors, and elsewhere in this Annual Report. References to “Notes” are Notes included in our Notes to 
Consolidated Financial Statements.  

Overview  

Halozyme is seeking to translate our unique knowledge of the tumor microenvironment to create novel therapies that can improve cancer 
survival. Our research focuses on human enzymes that alter the extracellular matrix and tumor microenvironment. The extracellular matrix is a 
complex matrix of proteins and carbohydrates surrounding the cell that provides structural support in tissues and orchestrates many important 
biological  activities,  including  cell  migration,  signaling  and  survival.  Over  many  years,  we  have  developed  unique  technology  and  scientific 
expertise enabling us to pursue this target-rich environment for the development of therapies.  

Our  proprietary  enzymes  can  be  used  to  facilitate  the  delivery  of  injected  drugs  and  fluids,  potentially  enhancing  the  efficacy  and  the 
convenience of other drugs or can be used to alter abnormal tissue structures for clinical benefit. We have chosen to exploit our technology and 
expertise  in  a  balanced  way  to  modulate  both  risk  and  spend  by:  (1)  developing  our  own  proprietary  products  in  therapeutic  areas  with 
significant unmet medical needs, with a focus on oncology, and (2) licensing our technology to biopharmaceutical companies to collaboratively 
develop products which combine our technology with the collaborators' proprietary compounds.  

The  majority  of  our  approved  product  and  product  candidates  are  based  on  rHuPH20,  our  patented  recombinant  human  hyaluronidase 
enzyme. rHuPH20 temporarily breaks down hyaluronic acid (HA), a naturally occurring substance that is a major component of the extracellular 
matrix in tissues throughout the body such as skin and cartilage. We believe this temporary degradation creates an opportunistic window for the 
improved subcutaneous delivery of injectable biologics, such as monoclonal antibodies and other large therapeutic molecules, as well as small 
molecules  and  fluids.  We  refer  to  the  application  of  rHuPH20  to  facilitate  the  delivery  of  other  drugs  or  fluids  as  Enhanze  ™  technology. 
rHuPH20 is also the active ingredient in our first commercially approved product, Hylenex ® recombinant.  

Our proprietary development pipeline consists primarily of clinical stage product candidates in oncology and diabetes. Our lead oncology 
program is PEGPH20 (PEGylated recombinant human hyaluronidase), a new molecular entity, under development for the systemic treatment of 
tumors that accumulate HA. When HA accumulates in a tumor, it can cause higher pressure in the tumor, reducing blood flow into the tumor and 
with that, reduced access of cancer therapies to the tumor. PEGPH20 works by temporarily degrading HA surrounding some cancer cells and 
results in reduced pressure and increased blood flow to the cancer with increased amounts of anticancer treatments administered concomitantly 
gaining access to the tumor. We are currently in Phase 2 clinical testing for PEGPH20 in metastatic pancreatic cancer (Study 109-202) , and we 
have recently initiated a clinical trial in non-small cell lung cancer (Study 107-201). We have also been investigating Hylene x recombinant for 
use as pre-treatment in patients with Type 1 diabetes using pumps and recombinant human cathepsin L (HTI-501) for the treatment of cellulite.  

Our  recent  receipt  of  Fast  Track  and  Orphan  Drug  designations  for  PEGPH20,  new  pre-clinical  data  further  supporting  the  pan-tumor 
potential  for  PEGPH20  and  investigator  interest  in  both  pancreatic  and  lung  cancer  trials  have  confirmed  PEGPH20  as  our  priority  product 
candidate for investment. As a result of ongoing evaluations to confirm and focus on the highest value opportunities, we have made the decision 
to seek collaborations with third parties or explore other strategic alternatives in order to exploit our diabetes and dermatology programs.  

Regarding  Enhanze,  we  currently  have  collaborations  with  F.  Hoffmann-La  Roche,  Ltd.  and  Hoffmann-La  Roche,  Inc.  (Roche),  Baxter 
Healthcare  Corporation  (Baxter),  Pfizer  Inc.  (Pfizer)  and  Janssen  Biotech,  Inc.  (Janssen),  with  one  product  approved  in  the  U.S.  and  three 
products approved for marketing in Europe from which we are receiving royalties and several others at various stages of development.  

31  

 
 
 
 
Our  operations  to  date  have  involved:  (i) building  infrastructure  for  and  staffing  our  operations;  (ii) acquiring,  developing  and  securing 
proprietary protection for our technology; (iii) developing our proprietary product pipeline; (iv) entering into and supporting our collaborations 
with  other  companies  to  advance  licensed  product  candidates;  and  (v) selling  our  own  approved  commercial  product,  Hylenex  recombinant. 
Currently, we have received only limited revenue from the sales of Hylenex recombinant, in addition to other revenues from our collaborations.  

Future revenues from the sales and/or royalties of our product candidates which have not been approved or have recently been approved 
will depend on the ability of Halozyme and our collaborators to develop, manufacture, secure regulatory approvals for and commercialize the 
product  candidates.  We  have  incurred  net  operating  losses  each  year  since  inception,  with  an  accumulated  deficit  of  approximately  $450.4 
million as of December 31, 2014 .  

Our 2014 and recent key accomplishments and events are as follows:  

•  

•  

•  

In  January  2015,  we  disclosed  initial  efficacy  and  safety  data  from  an  interim  assessment  of  Stage  1  of  Study  109-202,  a  Phase  2 
multicenter, randomized clinical trial evaluating PEGPH20 as a first-line therapy for patients with stage IV metastatic pancreatic cancer. 
Refer to PEGPH20 section under Part I, Item 1, Business , for further discussion of Study 109-202 data. We also presented the final 
results from Study 109-201, a multi-center, international open label dose escalation Phase 1b clinical study of PEGPH20 in combination 
with  gemcitabine  for  the  treatment  of  patients  with  stage  IV  metastatic  pancreatic  cancer  at  the  2015  Gastrointestinal  Cancers 
Symposium (also known as ASCO-GI meeting). Refer to PEGPH20 section under Part I, Item 1, Business , for further discussion of 
Study 109-202 data.  

In December 2014, we and Janssen entered into a collaboration and license agreement, under which Janssen has the worldwide license 
to  develop and  commercialize  products  combining  our  Enhanze  technology  with  Janssen  proprietary  biologics  directed  to  up  to  five 
targets.  Targets  may  be  selected  on  an  exclusive  or  non-exclusive  basis.  We  received  $15  million  for  the  license  of  one  specified 
exclusive target and four additional targets which Janssen has the right to elect upon payment of additional fees. We are also eligible to 
receive  additional  payments  upon  Janssen's  achievement  of  specified  development,  regulatory  and  sales-based  events,  totaling  up  to 
$566 million.  

In  November  2014,  we  announced  we  had  completed  a  corporate  strategy  review,  including  a  portfolio  review,  which  resulted  in  a 
decision to focus our resources on advancing PEGPH20 and to expand utilization of our Enhanze platform. The recent Fast Track and 
Orphan  Drug  designations  for  PEGPH20,  new  pre-clinical  data  further  supporting  the  pan-tumor  potential  for  PEGPH20,  and 
investigator interest in both pancreatic and lung cancer trials have confirmed PEGPH20 as our priority product for investment. With 
respect to our program investigating Hylenex recombinant for use with insulin pumps, we believe that additional clinical data will be 
required and are continuing to seek clarity with the U.S. Food and Drug Administration (FDA) on what data will be required, if any. 
Once we receive clarity, we intend to seek to enter into collaborations with third parties or explore other strategic alternatives in order to 
exploit this opportunity. We completed a reduction in our workforce of approximately 13% to align with these strategic priorities.

In  October  2014,  Baxter  announced  the  launch  and  first  shipments  of  HYQVIA  [Immune  Globulin  Infusion  10%  (Human)  with 
rHuPH20], Baxter's subcutaneous immunoglobulin treatment for adult patients with primary immunodeficiency in the U.S. HYQVIA 
was  approved  by  the  FDA  in  September  2014,  and  is  the  first  subcutaneous  immune  globulin  (IG)  treatment  approved  for  primary 
immunodeficiency patients with a dosing regimen requiring only one infusion up to once per month (every three to four weeks) and one 
injection site per infusion to deliver a full monthly therapeutic dose of IG. The majority of primary immunodeficiency patients today 
receive  intravenous  infusions  in  a  doctor’s  office  or  infusion  center,  and  current  subcutaneous  IG  treatments  require  weekly  or  bi-
weekly treatment with multiple infusion sites per treatment. The FDA's approval of HYQVIA was a significant milestone for us as it 
represented the first U.S. approved Biologics License Application (BLA) which utilized our rHuPH20 platform.  

In  July  2014,  we  resumed  enrollment  and  dosing  of  patients  in  our  ongoing  Study  109-202  evaluating  PEGPH20  in  patients  with 
pancreatic cancer under a revised clinical protocol. The study had previously been placed on clinical hold in April 2014 pending review 
by the independent Data Monitoring Committee (DMC) for the study and by the FDA of a possible difference in the thromboembolic 
event rate between the patients treated with PEGPH20 versus the patients treated without PEGPH20 in the trial.  

In June 2014, Roche launched the subcutaneous (SC) formulation of MabThera ® (rituximab) using rHuPH20 (MabThera SC) in Europe 
for the treatment of patients with common forms of non-Hodgkin lymphoma (NHL). Roche received European marketing approval in 
March  2014.  The  first  commercial  launch  of  MabThera  SC  triggered  a  $5  million  milestone  payment  under  the  License  and 
Collaboration Agreement between Halozyme and Roche. Following the launch of Herceptin ® SC in September 2013, MabThera SC is 
the second novel subcutaneous formulation of one of Roche's oncology products using our patented Enhanze technology to be launched 
in Europe.  

•  

In March 2014, Roche received European marketing approval for Roche's SC formation of MabThera (rituximab) for the treatment of 
patients  with  common  forms  of  non-Hodgkin  lymphoma  (NHL).  This  is  the  second  European  approval  for  a  novel  subcutaneous 
formulation of one of Roche's oncology products using our rHuPH20 technology.  

Results of Operations  

Comparison of Years Ended December 31, 2014, 2013 and 2012  

Product  Sales,  Net  —  Product  sales  increased  in  2014  compared  to  2013,  by  $13.4  million,  or  55%,  primarily  due  to  a  $9.8  million 
increase in product sales of bulk rHuPH20 for Roche collaboration products and a $4.1 million increase in product sales of Hylenex recombinant. 
Hylenex recombinant product sales increased to $13.2 million in 2014 from $9.0 million in 2013. Product sales increased in 2013 compared to 
2012 by $21.6 million, or 746%, primarily due to $14.8 million in product sales of bulk rHuPH20 for Roche and Baxter collaboration products, 
Herceptin SC  and  HyQvia.  The increase  was also due to  a  $6.8  million increase  in  product  sales of  Hylenex  recombinant.  Subsequent  to  the 
receipt of the  European  marketing approval of Roche's Herceptin SC  product  in August  2013  and  MabThera  SC  product in  March  2014  and 
Baxter's  HYQVIA  product  in  May  2013,  revenue  from  bulk  rHuPH20  supply  for  these  collaboration  products  was  recorded  as  product  sales 
revenue, instead of revenues under collaborative agreements.  

Royalties  –  Royalty  revenue  was  $9.4  million  in  2014  compared  to  $33,000  in  2013.  Royalties  relate  primarily  to  sales  of  Roche's 
Herceptin  SC.  The  increase  was  mainly  due  to  the  launch  of  Herceptin  SC  in  September  2013.  We  recognize  royalties  on  sales  of  the 
collaboration products by the collaborators in the quarter following the quarter in which the corresponding sales occur.

(1)   Subsequent to the European approvals of Roche's Herceptin SC product in August 2013 and MabThera SC product in March 2014 
and  Baxter's  HYQVIA  product  in  May  2013,  revenue  from  supply  of  bulk  rHuPH20  for  those  products  to  the  collaborators  was 
recorded as product sales.  

In 2014, we recognized $15.0 million in license fee revenue in connection with the Janssen Collaboration. In 2012, we recognized $9.5 
million in license fee revenue in connection with the Pfizer Collaboration. In 2012, we also recognized $8.0 million upon achievement of certain 
regulatory milestones under the Roche Collaboration. Revenue from reimbursements for research and development services and bulk rHuPh20 
supply  decreased  in  2014  compared  to  2013  mainly  due  to  revenue  from  supply  of  bulk  rHuPH20  for  Roche  collaboration  products  being 
recognized as product sales revenue in the current period, as opposed to revenue from reimbursements for research and development services in 
the  same  period  in  2013.  The  decrease  was  also  due  to  a  decrease  in  reimbursements  for  manufacturing  services  to  support  the  launches  by 
Roche and Baxter. Revenue from reimbursements for research and development services and bulk rHuPh20 supply increased in 2013 compared 
to 2012 due to the increase in reimbursements for manufacturing services to support the launches by Roche. Research and development services 
rendered  by  us  on  behalf  of  our  collaborators  are  at  the  request  of  the  collaborators;  therefore,  the  amount  of  future  revenues  related  to 
reimbursable research and development services and supply of bulk rHuPH20 is uncertain. We expect the non-reimbursement revenues under 
our  collaborative  agreements  to  continue  to  fluctuate  in  future  periods  based  on  our  collaborators’  abilities  to  meet  various  clinical  and 
regulatory milestones set forth in such agreements and our abilities to obtain new collaborative agreements.  

Cost  of  Product  Sales  —  Cost  of  product  sales  increased  in  2014  compared  to  2013,  by  $16.5  million,  or  264%,  primarily  due  to  the 
increased product sales of bulk rHuPH20 for Herceptin SC. Cost of product sales increased in 2013 compared to 2012, by $5.2 million, or 471%, 
primarily due to a $2.8 million increase in cost of product sales related to the increased Hylenex recombinant product sales and $2.3 million in 
cost of product sales related to the product sales of bulk rHuPH20 for Herceptin SC.

Prior to European marketing approvals of Roche's collaboration products, Herceptin SC in August 2013 and MabThera SC in March 2014, 
and  Baxter's  collaboration  HYQVIA  product  in  May  2013,  all  costs  related  to  the  manufacturing  of  bulk  rHuPH20  for  these  collaboration 
products were charged to research and development expenses in the periods such costs were incurred. Therefore, cost of product sales of bulk 
rHuPH20 for these collaboration products in 2013 was materially reduced due to the exclusion of the manufacturing costs that were charged to 
research and development expenses in the periods prior to receiving marketing approvals.  

Cost of product sales of bulk rHuPH20 for collaboration products in 2014 excluded $1.0 million in manufacturing costs, of which $0.9 
million  and  $0.1  million  were  charged  to  research  and  development  expenses  for  2013  and  2012,  respectively.  Cost  of  product  sales  of  bulk 
rHuPH20  for  collaboration  products  in  2013  excluded  $10.0  million  in  manufacturing  costs,  of  which  $9.0  million  and  $1.0  million  were 
charged to research and development expenses in 2013 and 2012, respectively. The estimated selling price of the zero-cost inventory of bulk 
rHuPH20 for Herceptin SC on hand as of December 31, 2013, was approximately $1.3 million. We sold all of this inventory in 2014. Going 
forward,  the  cost  of  product  sales  is  expected  to  be  approximately  83%  of  bulk  rHuPH20  product  sales  revenue.  There  was  no  HyQvia  API 
inventory on hand as of December 31, 2014 and 2013.

(1)   Subsequent to the European approvals of Roche's Herceptin SC product in August 2013 and MabThera SC product in March 2014 
and  Baxter's  HYQVIA  product  in  May  2013,  the  manufacturing  costs  of  bulk  rHuPH20  for  these  collaboration  products  were 
capitalized as inventory.  

(2)   Includes research, development and manufacturing expenses related to our proprietary rHuPH20 enzyme. These expenses were not 

designated to a specific program at the time the expenses were incurred.  

Research and development expenses relating to our PEGPH20 program in 2014 increased by 86%, compared to 2013 primarily due to the 
increased clinical trial activities mostly relating to Study 109-202. Research and development expenses relating to Hylenex recombinant program 
decreased in 2014 by 50% compared to 2013 mainly due to the completion of the technology transfer and validation campaign with a second 
manufacturer for Hylenex recombinant at the end of 2013. Research and development expenses relating to our Enhanze collaborations in 2014 
decreased by 78%, primarily due to a $12.0 million decrease resulting from capitalizing manufacturing costs for approved collaboration products 
in the current period, an $8.1 million decrease in other outsourced regulatory and manufacturing activities to support Roche and a $2.5 million 
decrease in preclinical activities to support Baxter. Subsequent to the European approvals of Roche's Herceptin SC product in August 2013 and 
MabThera  SC  product  in  March  2014  and  Baxter's  HYQVIA  product  in  May  2013,  the  manufacturing  costs  of  bulk  rHuPH20  for  these 
collaboration products  were capitalized  as inventory. We expect research and development costs to  increase in future  periods  as  we continue 
with our clinical trial programs and continue to develop and manufacture our product candidates.

Research and development expenses increased in 2013 compared to 2012 by $26.6 million, or 38%. Research and development expenses 
relating to our ultrafast insulin and PEGPH20 programs increased in 2013 compared to 2012 by $19.5 million, or 371%, and $6.3 million, or 
50%, respectively, primarily due to the increased clinical trial activities relating to the CONSISTENT 1 and on-going Phase 2 PEGPH20 clinical 
trials. Research and development expenses relating to our Enhanze collaborations increased in 2013 compared to 2012 by $5.0 million, or 19%, 
primarily due to a $9.8 million increase in manufacturing activities to support Roche's preparation for the launches of its collaboration product 
and  product  candidates;  offset  in  part  by  a  $4.6  million  decrease  in  manufacturing  expenses  to  support  Baxter's  launch  of  its  collaboration 
product.  

Selling,  General  and  Administrative  —  Selling,  general  and  administrative  (SG&A)  expenses  increased  in  2014  compared  to  2013  by 

$3.6 million, or 11%, due to the increase in compensation costs, including a $2.3 million increase in stock-based compensation.  

SG&A expenses increased in 2013 compared to 2012 by $7.5 million, or 30%, primarily due to a $3.9 million increase in compensation 
costs, including a $0.9 million increase in stock-based compensation, mainly resulting from an increase in headcount and higher bonus accruals, 
and a $1.8 million increase in marketing activities for Hylenex recombinant product.  

Interest Expense — Interest expense included interest expense and amortization of the debt discount related to the long-term debt acquired 
in December 2012. The increase of $2.3 million in 2014 as compared to 2013 was due to the $20.0 million increase in the principal balance in 
December 2013.  

Liquidity and Capital Resources  

Our principal sources of liquidity are our existing cash, cash equivalents and available-for-sale marketable securities. As of December 31, 
2014  ,  we  had  cash,  cash  equivalents  and  marketable  securities  of  approximately  $135.6  million.  We  will  continue  to  have  significant  cash 
requirements to support product development activities. The amount and timing of cash requirements will depend on the progress and success of 
our  clinical  development  programs,  regulatory  and  market  acceptance,  and  the  resources  we  devote  to  research  and  other  commercialization 
activities.  

We believe that our current cash, cash equivalents and marketable securities will be sufficient to fund our operations for at least the next 
twelve months. We currently anticipate total net cash burn of approximately $35 million to $45 million for the year ending December 31, 2015, 
depending on the progress of various preclinical and clinical programs, the timing of our manufacturing scale up and the achievement of various 
milestones  and  royalties  under  our  existing  collaborative  agreements.  We  expect  to  fund  our  operations  going  forward  with  existing  cash 
resources, anticipated revenues from our existing collaborations and cash that we may raise through future transactions. We may finance future 
cash  needs  through  any  one  of  the  following  financing  vehicles:  (i) the  public  offering  of  securities;  (ii) new  collaborative  agreements; 
(iii) expansions or revisions to existing collaborative relationships; (iv) private financings; and/or (v) other equity or debt financings.  

In  February  2012,  we  filed  an  automatic  shelf  registration  statement  on  Form  S-3  (Registration  No. 333-179444)  with  the  SEC,  which 
allows us, from time to time, to offer and sell equity, debt securities and warrants to purchase any of such securities, either individually or in 
units. We may, in the future, offer and sell equity, debt securities and warrants to purchase any of such securities, either individually or in units 
to  raise  capital  to  fund  the  continued  development  of  our  product  candidates,  the  commercialization  of  our  products  or  for  other  general 
corporate purposes.  

Our  existing  cash,  cash  equivalents  and  marketable  securities  may  not  be  adequate  to  fund  our  operations  until  we  become  cash  flow 
positive, if  ever.  We  cannot  be  certain  that  additional financing  will  be available  when  needed or,  if  available,  financing  will be obtained  on 
favorable  terms.  If  we  are  unable  to  raise  sufficient  funds,  we  may  need  to  delay,  scale  back  or  eliminate  some  or  all  of  our  research  and 
development programs, delay the launch of our product candidates, if approved, and/or restructure our operations. If we raise additional funds by 
issuing equity securities, substantial dilution to existing stockholders could result. If we raise additional funds by incurring debt financing, the 
terms of the debt may  involve significant cash payment obligations, the issuance of warrants that may ultimately dilute existing stockholders 
when exercised and covenants that may restrict our ability to operate our business.

Cash Flows  

Operating Activities  

Net cash used in operations was $47.5 million in 2014 compared to $49.3 million of net cash used in operations in 2013. The $1.8 million 
decrease in utilization of cash in operations was mainly due to the receipt of a $15.0 million license fee payment from the Janssen Collaboration; 
offset in part by the timing of the collection of accounts receivable and the payment of accounts payable.  

Net cash used in operations was $49.3 million in 2013 compared to $64.3 million of net cash used in 2012. The $15.0 million decrease in 
utilization of cash in operations was mainly due to receipts of the first commercial sale milestone payments totaling $14.0 million in 2013 from 
Roche and Baxter and timing of the collection of accounts receivable and the payment of accounts payable.  

Investing Activities  

Net cash used in investing activities was $33.0 million in 2014 compared to $47.9 million in 2013 and $1.4 million in 2012. This decrease 
in 2014 compared to 2013 was primarily due to a $53.9 million increase in proceeds from maturities of marketable securities; offset in part by a 
$39.9 million increase in purchases of marketable securities in 2014. The increase in net cash used in investing activities in 2013 as compared to 
2012 was primarily due to the purchases of marketable securities of $48.9 million in 2013.  

Financing Activities  

Net cash provided by financing activities was $114.5 million in 2014 compared to $25.1 million in 2013 and $112.8 million in 2012. Net 
cash provided by financing activities in 2014 consisted of $107.7 million in net proceeds from the sale of our common stock in February 2014 
and  $6.8 million in  net  proceeds  from option exercises. Net  cash provided by  financing activities in  2013  consisted of net proceeds  of  $20.0 
million from the amended long-term debt and $5.1 million in net proceeds from option exercises. Net cash provided by financing activities in 
2012 consisted of net proceeds of $81.5 million from the sale of our common stock in February 2012, net proceeds of $29.7 million from long-
term debt, and $1.7 million in net proceeds from option exercises.  

Long-Term Debt  

In December 2013, we entered into an Amended and Restated Loan and Security Agreement (the Loan Agreement) with Oxford Finance 
LLC (Oxford) and Silicon Valley Bank (SVB) (collectively, the Lenders), amending and restating in its entirety our original loan agreement with 
the Lenders, dated December 2012. The Loan Agreement provided for an additional $20 million principal amount of new term loan, bringing the 
total term loan balance to $50 million. The proceeds are to be used for working capital and general business requirements. The amended term 
loan  facility  matures  on  January 1,  2018. The  outstanding  term  loan  was  $49.9  million  as  of  December  31,  2014,  net  of  unamortized  debt 
discount of $0.1 million.  

In January 2015, we and the Lenders entered into a second amendment to the Loan Agreement (the Amendment) amending and restating 
the loan repayment schedule of the Loan Agreement. The amended and restated loan repayment schedule provides for interest only payments in 
arrears through January 2016, followed by consecutive equal monthly payments of principal and interest in arrears starting in February 2016 and 
continuing through the previously established maturity date. Consistent with the original loan, the Loan Agreement provides for a 7.55% interest 
rate on the term loan and a final interest payment equal to 8.5% of the original principal amount, or $4.25 million, which is due when the term 
loan becomes due or upon the prepayment of the facility. We have the option to prepay the outstanding balance of the term loan in full, subject 
to a prepayment fee of 1% to 3% depending upon when the prepayment occurs.  

The amended and restated term loan facility is secured by substantially all of the assets of the Company and Halozyme, Inc., except that the 
collateral  does  not  include  any  equity  interests  in  Halozyme,  Inc.,  any  intellectual  property  (including  all  licensing,  collaboration  and  similar 
agreements  relating  thereto),  and  certain  other  excluded  assets.  The  Loan  Agreement  contains  customary  representations,  warranties  and 
covenants by us, which covenants limit our ability to convey, sell, lease, transfer, assign or otherwise dispose of certain of our assets; engage in 
any business other than the businesses currently engaged in by us or reasonably related thereto; liquidate or dissolve; make certain management 
changes; undergo certain change of control events; create, incur, assume, or be liable with respect to certain indebtedness; grant certain liens; pay 
dividends and make certain other restricted payments;  

37  

 
 
 
 
make certain investments; make payments on any subordinated debt; and enter into transactions with any of our affiliates outside of the ordinary 
course of business or permit our subsidiaries to do the same. In addition, subject to certain exceptions, we are required to maintain with SVB our 
primary deposit accounts, securities accounts and commodities, and to do the same for our domestic subsidiary.  

The Loan Agreement also contains customary indemnification obligations and customary events of default, including, among other things, 
our failure to fulfill certain of our obligations under the Loan Agreement and the occurrence of a material adverse change which is defined as a 
material adverse change in our business, operations or condition (financial or otherwise), a material impairment of the prospect of repayment of 
any portion of the loan, or a material impairment in the perfection or priority of lender’s lien in the collateral or in the value of such collateral. In 
the event of default by us under the Loan Agreement, the Lenders would be entitled to exercise their remedies thereunder, including the right to 
accelerate the debt, upon which we may be required to repay all amounts then outstanding under the Loan Agreement, which could harm our 
financial condition.  

Off-Balance Sheet Arrangements  

As of December 31, 2014 , we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often 
referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet 
arrangements  or  other  contractually  narrow  or  limited  purposes.  In  addition,  we  did  not  engage  in  trading  activities  involving  non-exchange 
traded contracts. As such, we are not materially exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in 
these relationships.  

Contractual Obligations  

As of December 31, 2014 , future minimum payments due under our contractual obligations are as follows (in thousands):  

Payments Due by Period

(1)   Does not include milestone or contractual payment obligations contingent upon the achievement of certain milestones or events if the 
amount and timing of such obligations are unknown or uncertain. Our in-license agreement is cancelable with written notice within 
90 days. We may be required to pay up to approximately $9.3 million in milestone payments, plus sales royalties, in the event that all 
scientific research under these agreements is successful.  

(2)   Long-term debt obligations include future monthly interest payments based on a fixed rate of 7.55% and a final payment of $4.25 

million for our long-term debt due in January 2018.  

(3)   Includes  minimum  lease  payments  related  to  leases  of  our  office  and  research  facilities  and  certain  autos  under  non-cancelable 

operating leases.  

(4)   We have contracted with third-party manufacturers for the supply of bulk  rHuPH20 and fill/finish of  Hylenex  recombinant. Under 
these agreements, we are required to purchase certain quantities each year during the terms of the agreements. The amounts presented 
represent our estimates of the minimum required payments under these agreements.  

(5)   Excludes contractual obligations already recorded on our consolidated balance sheet as current liabilities. 

38  

 
 
 
 
   
  
  
  
  
  
  
  
  
Contractual  obligations  for  purchases  of  goods  or  services  include  agreements  that  are  enforceable  and  legally  binding  on  us  and  that 
specify  all  significant  terms,  including  fixed  or  minimum  quantities  to  be  purchased;  fixed,  minimum  or  variable  price  provisions;  and  the 
approximate timing of the transaction. For obligations with cancellation provisions, the amounts included in the preceding table were limited to 
the non-cancelable portion of the agreement terms or the minimum cancellation fee.  

For the restricted stock units granted, the number of shares issued on the date the restricted stock units vest is net of the minimum statutory 
withholding requirements that we pay in cash to the appropriate taxing authorities on behalf of our employees. The obligation to pay the relevant 
taxing authority is not included in the preceding table, as the amount is contingent upon continued employment. In addition, the amount of the 
obligation is unknown, as it is based in part on the market price of our common stock when the awards vest.  

The  expected  timing  of  payments  of  the  obligations  above  is  estimated  based  on  current  information.  Timing  of  payments  and  actual 

amounts paid may be different, depending on the time of receipt of goods or services, or changes to agreed-upon amounts for some obligations.  

Our future capital uses and requirements depend on numerous forward-looking factors. These factors may include, but are not limited to, 

the following:  

•  

•  

•  

the rate of progress and cost of research and development activities; 

the number and scope of our research activities; 

the costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights; 

•   our ability to establish and maintain product discovery and development collaborations, including scale-up manufacturing costs for our 

collaborators’ product candidates;  

the amount of royalties from our collaborators; 

the amount of product sales for Hylenex recombinant; 

the costs of obtaining and validating additional manufacturers of Hylenex recombinant; 

the effect of competing technological and market developments; 

the terms and timing of any collaborative, licensing and other arrangements that we may establish; and 

the extent to which we acquire or in-license new products, technologies or businesses.

Critical Accounting Policies and Estimates  

This discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which 
have  been  prepared  in  accordance  with  U.S.  generally  accepted  accounting  principles,  or  U.S.  GAAP.  The  preparation  of  our  consolidated 
financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses 
and  related  disclosure  of  contingent  assets  and  liabilities.  We  review  our  estimates  on  an  ongoing  basis.  We  base  our  estimates  on  historical 
experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for 
making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions 
or  conditions.  We  believe  the  following  accounting  policies  to  be  critical  to  the  judgments  and  estimates  used  in  the  preparation  of  our 
consolidated financial statements.  

Revenue Recognition  

We generate  revenues from  product sales  and collaborative  agreements. Payments  received under collaborative  agreements may include 
nonrefundable fees at the inception of the agreements, license fees, milestone payments for specific achievements designated in the collaborative 
agreements, reimbursements of research and development services and supply of bulk rHuPH20 and/or royalties on sales of products resulting 
from collaborative arrangements.  

We  recognize  revenue  in  accordance  with  the  authoritative  guidance  on  revenue  recognition.  Revenue  is  recognized  when  all  of  the 
following criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the 
seller’s price to the buyer is fixed or determinable; and (4) collectibility is reasonably assured.  

39  

 
 
 
 
Refer  to  Note  2  for  a  further  discussion  of  our  revenue  recognition  policies  for  product  sales  and  revenues  under  our  collaborative 

agreements and Note 4 for a further discussion of our collaborative agreements.  

Share-Based Payments  

We  use  the  fair  value  method  to  account  for  share-based  payments  in  accordance  with  the  authoritative  guidance  for  share-based 
compensation. The fair value of each option award is estimated on the date of grant using a Black-Scholes-Merton option pricing model (Black-
Scholes  model)  that  uses  assumptions  regarding  a  number  of  complex  and  subjective  variables.  Changes  in  these  assumptions  may  lead  to 
variability with respect to the amount of expense we recognize in connection with share-based payments. Refer to Note 2 for a further discussion 
of share-based payments.  

Research and Development Expenses  

Research and development expenses include salaries and benefits, facilities and other overhead expenses, external clinical trial expenses, 
research  related  manufacturing  services,  contract  services  and  other  outside  expenses.  Research  and  development  expenses  are  charged  to 
operations  as  incurred  when  these  expenditures  relate  to  our  research  and  development  efforts  and  have  no  alternative  future  uses.     After 
receiving marketing approval from the FDA or comparable regulatory agencies in foreign countries for a product, costs related to purchases or 
manufacturing of bulk rHuPH20 for such product are capitalized as inventory. The manufacturing costs of bulk rHuPH20 for the collaboration 
products, Herceptin SC, MabThera SC and HYQVIA, which were incurred after the receipt of the European marketing approvals are capitalized 
as inventory. Refer to Note 2 for a further discussion of research and development expenses.  

Due to the uncertainty in obtaining the FDA and other regulatory approvals, our reliance on third parties and competitive pressures, we are 
unable to estimate with any certainty the additional costs we will incur in the continued development of our proprietary product candidates for 
commercialization.  However,  we  expect  our  research  and  development  expenses  to  increase  this  year  as  we  continue  with  our  clinical  trial 
programs and continue to develop and manufacture our product candidates.  

Clinical development timelines, likelihood of success and total costs vary widely. We anticipate that we will make ongoing determinations 
as to which research and development projects to pursue and how much funding to direct to each project on an ongoing basis in response to 
existing resource levels, the scientific and clinical progress of each product candidate, and other market and regulatory developments. We plan 
on  focusing  our  resources  on  those  proprietary  and  collaboration  product  candidates  that  represent  the  most  valuable  economic  and  strategic 
opportunities.  

Product  candidate  completion  dates  and  costs  vary  significantly  for  each  product  candidate  and  are  difficult  to  estimate.  The  lengthy 
process  of  seeking  regulatory  approvals  and  the  subsequent  compliance  with  applicable  regulations  require  the  expenditure  of  substantial 
resources. Any failure by us to obtain, or any delay in obtaining, regulatory approvals could cause our research and development expenditures to 
increase and, in turn, have a material adverse effect on our results of operations. We cannot be certain when, or if, our product candidates will 
receive regulatory approval or whether any net cash inflow from our other product candidates, or development projects, will commence.

Item 7A.   Quantitative and Qualitative Disclosures About Market Risk 

As of December 31, 2014 , our cash equivalents and marketable securities consisted of investments in money market funds and corporate 
debt obligations. These investments were made in accordance with our investment policy which specifies the categories, allocations, and ratings 
of securities we may consider for investment. The primary objective of our investment activities is to preserve principal while at the same time 
maximizing the income we receive without significantly increasing risk. Some of the financial instruments that we invest in could be subject to 
market  risk.  This  means  that  a  change  in  prevailing  interest  rates  may  cause  the  value  of  the  instruments  to  fluctuate.  For  example,  if  we 
purchase a security that was issued with a fixed interest rate and the prevailing interest rate later rises, the value of that security will probably 
decline. As of December 31, 2014 based on our current investment portfolio, we do not believe that our results of operations would be materially 
impacted by an immediate change of 10% in interest rates.  

We  do  not  hold  or  issue  derivatives,  derivative  commodity  instruments  or  other  financial  instruments  for  speculative  trading  purposes. 
Further,  we  do  not  believe  our  cash,  cash  equivalents  and  marketable  securities  have  significant  risk  of  default  or  illiquidity.  We  made  this 
determination based on discussions with our investment advisors and a review of our holdings. While we believe our cash, cash equivalents and 
marketable securities do not contain excessive risk, we cannot provide absolute assurance that in the future our investments will not be subject to 
adverse changes in market value. All of our cash equivalents and marketable securities are recorded at fair market value.  

Item 8.   Financial Statements and Supplementary Data 

Our financial statements are annexed to this report beginning on page F-1.  

Item 9.   Changes In and Disagreements with Accountants on Accounting and Financial Disclosure 

None.  

Item 9A.  Control and Procedures 

Evaluation of Disclosure Controls and Procedures  

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Exchange Act 
reports is recorded, processed, summarized and reported within the timelines specified in the Securities and Exchange Commission’s rules and 
forms,  and  that  such  information  is  accumulated  and  communicated  to  our  management,  including  our  Chief  Executive  Officer  and  Chief 
Financial Officer, as appropriate, to allow timely decision regarding required disclosure. In designing and evaluating the disclosure controls and 
procedures, management recognized that any controls and procedures, no matter how well designed and operated, can only provide reasonable 
assurance of achieving the desired control objectives, and in reaching a reasonable level of assurance, management necessarily was required to 
apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.  

Under  the  supervision  and  with  the  participation  of  our  management,  including  our  principal  executive  officer  and  principal  financial 
officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under 
the Securities Exchange Act of 1934, as amended. Based on this evaluation, our principal executive officer and our principal financial officer 
concluded that our disclosure controls and procedures were effective as of the end of the period covered by this Annual Report on Form 10-K.  

Changes in Internal Control Over Financial Reporting  

There  have  been  no  significant  changes  in  our  internal  control  over  financial  reporting  that  occurred  during  the  quarter  ended 

December 31, 2014 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting  

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over 
financial  reporting  is  defined  in  Rule 13a-15(f)  and  Rule 15d-15(f)  promulgated  under  the  Securities  Exchange  Act  of  1934  as  a  process 
designed  by,  or  under  the  supervision  of,  our  principal  executive  and  principal  financial  officers  and  effected  by  our  board  of  directors, 
management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial 
statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:  

•   Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets; 

•   Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with 
generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of our 
management and directors; and  

•   Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that 

could have a material effect on our financial statements.  

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any 
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that 
the degree of compliance with the policies or procedures may deteriorate.  

Our  management  assessed  the  effectiveness  of  our  internal  control  over  financial  reporting  as  of  December 31,  2014  .  In  making  this 
assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in 
Internal  Control-Integrated  Framework  (2013  framework)  (the  COSO  criteria).  Based  on  our  assessment,  management  concluded  that,  as  of 
December 31, 2014 , our internal control over financial reporting is effective based on the COSO criteria.

The  independent  registered  public  accounting  firm  that  audited  the  consolidated  financial  statements  that  are  included  in  this  Annual 
Report on Form 10-K has issued an audit report on the effectiveness of our internal control over financial reporting as of December 31, 2014 . 
The report appears below.  

Report of Independent Registered Public Accounting Firm  

The Board of Directors and Stockholders  
Halozyme Therapeutics, Inc.  

We  have  audited  Halozyme  Therapeutics,  Inc.’s  internal  control  over  financial  reporting  as  of  December 31,  2014  ,  based  on  criteria 
established  in  Internal  Control  -  Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission 
(2013 framework) (the COSO criteria). Halozyme Therapeutics, Inc.’s management is responsible for maintaining effective internal control over 
financial  reporting,  and  for  its  assessment  of  the  effectiveness  of  internal  control  over  financial  reporting  included  in  the  accompanying 
Management’s  Report  on  Internal  Control  Over  Financial  Reporting.  Our  responsibility  is  to  express  an  opinion  on  the  company’s  internal 
control over financial reporting based on our audit.  

We  conducted  our  audit  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  effective  internal  control  over  financial 
reporting  was  maintained  in  all  material  respects.  Our  audit  included  obtaining  an  understanding  of  internal  control  over  financial  reporting, 
assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the 
assessed  risk,  and  performing  such  other  procedures  as  we  considered  necessary  in  the  circumstances.  We  believe  that  our  audit  provides  a 
reasonable basis for our opinion.  

A  company’s 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 generally accepted accounting principles. 
A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, 
in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance 
that  transactions  are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in  accordance  with  generally  accepted  accounting 
principles,  and  that  receipts  and  expenditures  of  the  company  are  being  made  only  in  accordance  with  authorizations  of  management  and 
directors  of  the  company;  and  (3) provide  reasonable  assurance  regarding  prevention  or  timely  detection  of  unauthorized  acquisition,  use,  or 
disposition of the company’s assets that could have a material effect on the financial statements.  

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of 
any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or 
that the degree of compliance with the policies or procedures may deteriorate.  

In our opinion, Halozyme Therapeutics, Inc. maintained, in all material respects, effective internal control over financial reporting as of 

December 31, 2014 , based on the COSO criteria .  

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States),  the

Report of Independent Registered Public Accounting Firm  

The Board of Directors and Stockholders  
Halozyme Therapeutics, Inc.  

We have audited the accompanying consolidated balance sheets of Halozyme Therapeutics, Inc. as of December 31, 2014 and 2013, and 
the related consolidated statements of operations, comprehensive loss, cash flows, and stockholders’ equity (deficit) for each of the three years in 
the period ended December 31, 2014.  Our audits also included the financial statement schedule listed in the Index at Item 15(a). These financial 
statements  and  schedule  are  the  responsibility  of  the  Company's  management.  Our  responsibility  is  to  express  an  opinion  on  these  financial 
statements and schedule 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. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit 
also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial 
statement presentation. We believe that our audits provide a reasonable basis for our opinion.  

In  our  opinion,  the  financial  statements  referred  to  above  present  fairly,  in  all  material  respects,  the  consolidated  financial  position  of 
Halozyme Therapeutics, Inc. at December 31, 2014 and 2013, and the consolidated results of its operations and its cash flows for each of the 
three years in the period ended December 31, 2014, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the 
related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material 
respects the information set forth therein. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Halozyme 
Therapeutics,  Inc.’s  internal  control  over  financial  reporting  as  of  December 31,  2014,  based  on  criteria  established  in  Internal  Control  -
Integrated Framework issued  by  the Committee  of  Sponsoring Organizations of the  Treadway Commission (2013  framework)  and  our report 
dated March 2, 2015 expressed an unqualified opinion thereon.

Notes to Consolidated Financial Statements  

1.   Organization and Business 

Halozyme Therapeutics, Inc. is seeking to translate our unique knowledge of the tumor microenvironment to create novel therapies that can 
improve  cancer  survival.  Our  research  focuses  on  human  enzymes  that  alter  the  extracellular  matrix  and  tumor  microenvironment.  The 
extracellular  matrix  is  a  complex  matrix  of  proteins  and  carbohydrates  surrounding  the  cell  that  provides  structural  support  in  tissues  and 
orchestrates many important biological activities, including cell migration, signaling and survival. Over many years, we have developed unique 
technology and scientific expertise enabling us to pursue this target-rich environment for the development of therapies.  

Our  proprietary  enzymes  can  be  used  to  facilitate  the  delivery  of  injected  drugs  and  fluids,  potentially  enhancing  the  efficacy  and  the 
convenience of other drugs or can be used to alter abnormal tissue structures for clinical benefit. We have chosen to exploit our technology and 
expertise  in  a  balanced  way  to  modulate  both  risk  and  spend  by:  (1)  developing  our  own  proprietary  products  in  therapeutic  areas  with 
significant unmet medical needs, with a focus on oncology, and (2) licensing our technology to biopharmaceutical companies to collaboratively 
develop products which combine our technology with the collaborators' proprietary compounds.  

The  majority  of  our  approved  product  and  product  candidates  are  based  on  rHuPH20,  our  patented  recombinant  human  hyaluronidase 
enzyme. rHuPH20 temporarily breaks down hyaluronic acid (HA), a naturally occurring substance that is a major component of the extracellular 
matrix in tissues throughout the body such as skin and cartilage. We believe this temporary degradation creates an opportunistic window for the 
improved subcutaneous delivery of injectable biologics, such as monoclonal antibodies and other large therapeutic molecules, as well as small 
molecules  and  fluids.  We  refer  to  the  application  of  rHuPH20  to  facilitate  the  delivery  of  other  drugs  or  fluids  as  Enhanze  ™  technology. 
rHuPH20 is also the active ingredient in our first commercially approved product, Hylenex ® recombinant.  

Our proprietary development pipeline consists primarily of clinical stage product candidates in oncology and diabetes. Our lead oncology 
program is PEGPH20 (PEGylated recombinant human hyaluronidase), a new molecular entity, under development for the systemic treatment of 
tumors that accumulate HA. When HA accumulates in a tumor, it can cause higher pressure in the tumor, reducing blood flow into the tumor and 
with that, reduced access of cancer therapies to the tumor. PEGPH20 works by temporarily degrading HA surrounding some cancer cells and 
results in reduced pressure and increased blood flow to the cancer with increased amounts of anticancer treatments administered concomitantly 
gaining access to the tumor. We are currently in Phase 2 clinical testing for PEGPH20 in metastatic pancreatic cancer (Study 109-202), and we 
have recently initiated a clinical trial in non-small cell lung cancer (Study 107-201).  

Regarding  Enhanze,  we  currently  have  collaborations  with  F.  Hoffmann-La  Roche,  Ltd.  and  Hoffmann-La  Roche,  Inc.  (Roche),  Baxter 
Healthcare  Corporation  (Baxter),  Pfizer  Inc.  (Pfizer)  and  Janssen  Biotech,  Inc.  (Janssen),  with  one  product  approved  in  the  U.S.  and  three 
products approved for marketing in Europe from which we are receiving royalties and several others at various stages of development.  

Except where specifically noted or the context otherwise requires, references to “Halozyme,” “the Company,” “we,” “our,” and “us” in 
these Notes to Consolidated Financial Statements refer to Halozyme Therapeutics, Inc. and its wholly owned subsidiary, Halozyme, Inc., and 
Halozyme, Inc.'s wholly owned subsidiary, Halozyme Holdings Ltd.

2.   Summary of Significant Accounting Policies 

Basis of Presentation  

The consolidated financial statements include the accounts of Halozyme Therapeutics, Inc. and our wholly owned subsidiary, Halozyme, 
Inc., and Halozyme, Inc.'s wholly owned subsidiary, Halozyme Holdings Ltd. All intercompany accounts and transactions have been eliminated.  

Reclassifications  

Certain prior period amounts have been reclassified to conform to the current period presentation. Specifically, we have reclassified $0.6 

million from accrued expenses to other long-term liabilities in the consolidated balance sheet at December 31, 2013.  

Use of Estimates  

The  preparation  of  consolidated  financial  statements  in  conformity  with  U.S.  generally  accepted  accounting  principles  (“U.S.  GAAP”) 
requires  management  to  make  estimates  and  assumptions  that  affect  the  amounts  reported  in  our  consolidated  financial  statements  and 
accompanying notes. On an ongoing basis, we evaluate our estimates and judgments, which are based on historical and anticipated results and 
trends  and  on  various  other  assumptions  that  management  believes  to  be  reasonable  under  the  circumstances.  By  their  nature,  estimates  are 
subject to an inherent degree of uncertainty and, as such, actual results may differ from management’s estimates.  

Cash Equivalents and Marketable Securities  

Cash  equivalents  consist  of  highly  liquid  investments,  readily  convertible  to  cash,  that  mature  within  ninety  days  or  less  from  date  of 

purchase. Our cash equivalents consist of money market funds.  

Marketable  securities  are  investments  with  original  maturities  of  more  than  ninety  days  from  the  date  of  purchase  that  are  specifically 
identified to fund current operations. Marketable securities are considered available-for-sale. These investments are classified as current assets, 
even though the stated maturity date may be one year or more beyond the current balance sheet date which reflects management's intention to 
use the proceeds from the sale of these investments to fund our operations, as necessary. Such available-for-sale investments are carried at fair 
value with unrealized gains and losses recorded in other comprehensive gain (loss) and included as a separate component of stockholders' equity 
(deficit). The cost of marketable securities is adjusted for amortization of premiums or accretion of discounts to maturity, and such amortization 
or  accretion  is  included  in  investment  and  other  income,  net  in  the  consolidated  statements  of  operations.  We  use  the  specific  identification 
method  for  calculating  realized  gains  and  losses  on  marketable  securities  sold.  Realized  gains  and  losses  and  declines  in  value  judged  to  be 
other-than-temporary  on  marketable  securities,  if  any,  are  included  in  investment  and  other  income,  net  in  the  consolidated  statements  of 
operations.  

Restricted Cash  

Under the terms of the leases on our facilities, we are required to maintain letters of credit as security deposits during the terms of such 

leases. At December 31, 2014 and 2013 , restricted cash of $0.5 million was pledged as collateral for the letters of credit.  

Fair Value of Financial Instruments  

The  authoritative  guidance  for  fair  value  measurements  establishes  a  three  tier  fair  value  hierarchy, which  prioritizes  the inputs  used  in 
measuring  fair  value.  These  tiers  include:  Level  1,  defined  as  observable  inputs  such  as  quoted  prices  in  active  markets;  Level  2,  defined  as 
inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in 
which little or no market data exists, therefore requiring an entity to develop its own assumptions.  

Our  financial  instruments  include  cash  equivalents,  available-for-sale  marketable  securities,  accounts  receivable,  prepaid  expenses, 
accounts payable, accrued expenses and long-term debt. Fair value estimates of these instruments are made at a specific point in time, based on 
relevant  market  information.  These  estimates  may  be  subjective  in  nature  and  involve  uncertainties  and  matters  of  significant  judgment  and 
therefore cannot be determined with precision. The carrying amount of cash equivalents,  

F-8  

 
 
 
 
accounts receivable, prepaid expenses, accounts payable and accrued expenses are generally considered to be representative of their respective 
fair values because of the short-term nature of those instruments. Further, based on the borrowing rates currently available for loans with similar 
terms, we believe the fair value of long-term debt approximates its carrying value.  

Available-for-sale  marketable  securities  consist  of  corporate  debt  securities,  commercial  paper  and  certificates  of  deposit  and  were 
measured at fair value using Level 2 inputs. Level 2 financial instruments are valued using market prices on less active markets and proprietary 
pricing  valuation  models  with  observable  inputs,  including  interest  rates,  yield  curves,  maturity  dates,  issue  dates,  settlement  dates,  reported 
trades, broker-dealer quotes, issue spreads, benchmark securities or other market related data. We obtain the fair value of Level 2 investments 
from our investment manager, who obtains these fair values from a third-party pricing service. We validate the fair values of Level 2 financial 
instruments provided by our investment manager by comparing these fair values to a third-party pricing source.  

The following table summarizes, by major security type, our cash equivalents and marketable securities that are measured at fair value on a 

recurring basis and are categorized using the fair value hierarchy (in thousands):

There were no transfers between Level 1 and Level 2 of the fair value hierarchy for the years ended December 31, 2014 and 2013 . We 

have no instruments that are classified within Level 3 as of December 31, 2014 and 2013 .  

Concentrations of Credit Risk, Sources of Supply and Significant Customers  

We are subject to credit risk from our portfolio of cash equivalents and marketable securities. These investments were made in accordance 
with our investment policy which specifies the categories, allocations, and ratings of securities we may consider for investment. The primary 
objective of our investment activities is to preserve principal while at the same time maximizing the income we receive without significantly 
increasing  risk.  We  maintain  our  cash  and  cash  equivalent  balances  with  one major  commercial  bank  and  marketable  securities  with  another 
financial institution. Deposits held with the financial institutions exceed the amount of insurance provided on such deposits. We are exposed to 
credit  risk  in  the  event  of  a  default  by  the  financial  institutions  holding  our  cash,  cash  equivalents  and  marketable  securities  to  the  extent 
recorded on the balance sheet.  

We  are  also  subject  to  credit  risk  from  our  accounts  receivable  related  to  our  product  sales  and  revenues  under  our  license  and 
collaborative agreements. We have license and collaborative agreements with pharmaceutical companies under which we receive payments for 
license  fees,  milestone  payments  for  specific  achievements  designated  in  the  collaborative  agreements,  reimbursements  of  research  and 
development services and supply of bulk formulation of rHuPH20. In addition, we sell Hylenex  ® recombinant in the United States to a limited 
number  of  established  wholesale  distributors  in  the  pharmaceutical  industry.  Credit  is  extended  based  on  an  evaluation  of  the  customer’s 
financial  condition,  and  collateral  is  not  required.  Management  monitors  our  exposure  to  accounts  receivable  by  periodically  evaluating  the 
collectibility of the accounts receivable based on a variety of factors including the length of time the receivables are past due, the financial health 
of the customer and historical experience. Based upon the review of these factors, we recorded no allowance for doubtful accounts at December 
31, 2014 and 2013 . Approximately 76% and 81% of the accounts receivable balance at December 31, 2014 and 2013, respectively, represents 
amounts due from Roche and Pfizer.

For the years ended December 31, 2014, 2013 and 2012 , we had no foreign based operations. As of December 31, 2014 and 2013 , we had 

$0.4 million and $0.8 million of research equipment in Germany.  

We rely on two  third-party  manufacturers for  the  supply of bulk rHuPH20 for  use  in the  manufacture  of  Hylenex recombinant and our 
other collaboration products and product candidates. Payments due to these suppliers represented 0% and 9% of the accounts payable balance at 
December 31, 2014 and 2013 , respectively. We also rely on a third-party manufacturer for the fill and finish of Hylenex recombinant product 
under  a  contract.  Payments  due  to  this  supplier  represented  6%  and  2%  of  the  accounts  payable  balance  at  December  31,  2014  and  2013  , 
respectively.  

Accounts Receivable, Net  

Accounts receivable is recorded at the invoiced amount and is non-interest bearing. Accounts receivable is recorded net of allowances for 
doubtful accounts, cash discounts for prompt payment, distribution fees and chargebacks. We recorded no allowance for doubtful accounts at 
December 31, 2014 and 2013 as the collectibility of accounts receivable was reasonably assured.  

Inventories  

Inventories are stated at lower of cost or market. Cost is determined on a first-in, first-out basis. Inventories are reviewed periodically for 
potential excess, dated or obsolete status. Management evaluates the carrying value of inventories on a regular basis, taking into account such 
factors as historical and anticipated future sales compared to quantities on hand, the price we expect to obtain for products in their respective 
markets compared with historical cost and the remaining shelf life of goods on hand.  

Prior to receiving marketing approval from the U.S. Food and Drug Administration (“FDA”) or comparable regulatory agencies in foreign 
countries,  costs  related  to  purchases  of  bulk  rHuPH20  and  raw  materials  and  the  manufacturing  of  the  product  candidates  are  recorded  as 
research  and  development  expense.  All  direct  manufacturing  costs  incurred  after  receiving  marketing  approval  are  capitalized  as  inventory. 
Inventories used in clinical trials are expensed at the time the inventories are packaged for the clinical trials.  

As  of  December  31,  2014  and  2013  ,  inventories  consisted  of  $3.0  million  and  $2.6  million  of  Hylenex  recombinant  inventory, 
respectively,  and  $3.4 million  and $3.5  million of bulk  rHuPH20,  respectively,  for use  in the  manufacture  of Roche's collaboration  products. 
Roche received European marketing approval for Herceptin SC  ® and MabThera  ® SC in August 2013 and March 2014, respectively. As such, 
direct manufacturing costs of bulk rHuPH20 for these collaboration products incurred after the receipt of the European marketing approvals are 
capitalized as inventory.

Property and Equipment, Net  

Property and equipment are recorded at cost, less accumulated depreciation and amortization. Equipment is depreciated using the straight-
line method over their estimated useful lives of three years and leasehold improvements are amortized using the straight-line method over the 
estimated useful life of the asset or the lease term, whichever is shorter. Leased buildings under build-to-suit lease arrangements are capitalized 
and included in property and equipment when we are involved in the construction of the structural improvements or take construction risk prior 
to the commencement of the lease. Upon completion of the construction under the build-to-suit leases, we assess whether those arrangements 
qualify  for  sales  recognition  under  the  sale-leaseback  accounting  guidance.  If  we  continue  to  be  the  deemed  owner,  the  facilities  would  be 
accounted for as financing leases.  

Impairment of Long-Lived Assets  

We  account  for  long-lived  assets 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. For the year ended 
December 31, 2014, we recorded an impairment of $0.2 million relating to manufacturing equipment. For the year ended December 31, 2013, 
there was no impairment of the value of long-lived assets.  

Deferred Rent  

Rent  expense  is  recorded  on  a  straight-line  basis  over  the  initial  term  of  the  lease.  The  difference  between  rent  expense  accrued  and 

amounts paid under lease agreements is recorded as deferred rent in the accompanying consolidated balance sheets.  

Comprehensive Income (Loss)  

Comprehensive income (loss) is defined as the change in equity during the period from transactions and other events and circumstances 

from non-owner sources.  

Revenue Recognition  

We generate revenues from product sales and collaborative agreements. Payments received under collaborative agreements may include 
nonrefundable fees at the inception of the agreements, license fees, milestone payments for specific achievements designated in the collaborative 
agreements, reimbursements of research and development services and supply of bulk rHuPH20, and/or royalties on sales of products resulting 
from collaborative arrangements.  

We  recognize  revenues  in  accordance  with  the  authoritative  guidance  for  revenue  recognition.  We  recognize  revenue  when  all  of  the 
following criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the 
seller’s price to the buyer is fixed or determinable; and (4) collectibility is reasonably assured.  

Product Sales, Net  

Hylenex Recombinant  

In December 2011, we reintroduced Hylenex recombinant to the market. We sell Hylenex recombinant in the U.S. to wholesale pharmaceutical 
distributors, who sell the product to hospitals and other end-user customers. Sales to wholesalers provide for selling prices that are fixed on the 
date  of  sale,  although  we  offer  discounts  to  certain  group  purchasing  organizations  (“GPOs”),  hospitals  and  government  programs.  The 
wholesalers take the title to the product, bear the risk of loss of ownership and have economic substance to the inventory. Further, we have no 
significant obligations for future performance to generate pull-through sales.  

Prior  to  December  31,  2013,  Hylenex  recombinant  had  a  limited  sales  history,  and  we  could  not  reliably  estimate  expected  returns  and 
chargebacks of the product at the time the product was sold to the wholesalers. Accordingly, we deferred the recognition of revenue on sales of 
Hylenex recombinant to wholesalers, and instead, recognized revenue at the time when evidence existed to confirm that pull-through sales from 
wholesalers to the hospitals or other end-user customers had occurred or the right of return no longer existed, whichever occurred earlier. At the 
time product sales revenue was recognized, we recorded allowances for product returns and chargebacks based on our best estimates at the time. 
Shipments of product that were not recognized as revenue were treated as deferred revenue.  

F-11  

 
 
 
 
At December 31, 2013, we had developed sufficient historical experience and data to reasonably estimate future returns and chargebacks of 
Hylenex recombinant. As a result, effective December 31, 2013, we began recognizing Hylenex recombinant product sales and related cost of 
product sales at the time title transfers to the wholesalers.  

Upon recognition of revenue from product sales of Hylenex recombinant, we record certain sales reserves and allowances as a reduction to 

gross revenue. These reserves and allowances include:  

•   Product Returns . We allow the wholesalers to return product that is damaged or received in error. In addition, we accept unused 
product to be  returned  beginning  six months prior  to and ending twelve  months  following product expiration.  Our  estimates for 
expected returns of expired products are based primarily on an ongoing analysis of historical return patterns.  

•   Distribution Fees . The distribution fees, based on contractually determined rates, arise from contractual agreements we have with 
certain  wholesalers  for  distribution  services  they  provide  with  respect  to  Hylenex  recombinant.  These  fees  are  generally  a  fixed 
percentage of the price of the product purchased by the wholesalers.  

•   Prompt  Payment  Discounts  .  We offer  cash discounts  to certain wholesalers as an  incentive  to  meet certain  payment terms.  We 
estimate  prompt  payment  discounts  based  on  contractual  terms,  historical  utilization  rates,  as  available,  and  our  expectations 
regarding future utilization rates.      

•   Other  Discounts  and  Fees  .  We  provide  discounts  to  end-user  members  of  certain  GPOs  under  collective  purchasing  contracts 
between us and the GPOs. We also provide discounts to certain hospitals, who are members of the GPOs, with which we do not 
have  contracts.  The  end-user  members  purchase  products  from  the  wholesalers  at  a  contracted  discounted  price,  and  the 
wholesalers then charge back to us the difference between the current retail price and the price the end-users paid for the product. 
We  also  incur  GPO  administrative  service  fees  for  these  transactions.  In  addition,  we  provide  predetermined  discounts  under 
certain  government  programs.  Our  estimate  for  these  chargebacks  and  fees  take  into  consideration  contractual  terms,  historical 
utilization rates, as available, and our expectations regarding future utilization rates.  

Allowances for product returns and chargebacks  are  based on amounts owed or to  be  claimed on the  related  sales. We  believe  that our 
estimated  product  returns  for Hylenex  recombinant  requires  a high  degree of judgment and is subject to  change based on our  experience and 
certain  quantitative  and  qualitative  factors.  In  order  to  develop  a  methodology  to  reliably  estimate  future  returns  and  provide  a  basis  for 
recognizing revenue on sales to wholesale distributors, we analyzed many factors, including, without limitation: (1) actual Hylenex recombinant 
product return history, taking into account product expiration dating at the time of shipment, (2) re-order activities of the wholesalers as well as 
their customers and (3) levels of inventory at the wholesale channel. We have monitored actual return history on an individual product lot basis 
since product launch. We considered the dating of product at the time of shipment into the distribution channel and changes in the estimated 
levels of inventory within the distribution channel to estimate our exposure for returned product. We considered historical chargebacks activity 
and current contract prices to estimate our exposure for returned product. Based on such data, we believe we have the information needed to 
reasonably estimate product returns and chargebacks.  

We recognize product sales allowances as a reduction of product sales in the same period the related revenue is recognized. Because of the 
shelf life of Hylenex recombinant and our lengthy return period, there may be a significant period of time between when the product is shipped 
and  when  we  issue  credits  on  returned  product.  If  actual  results  differ  from  our  estimates,  we  will  be  required  to  make  adjustments  to  these 
allowances in the future, which could have an effect on product sales revenue and earnings in the period of adjustments.  

Bulk rHuPH20  

Subsequent to receiving marketing approval from the FDA or comparable regulatory agencies in foreign countries, sales of bulk rHuPH20 
for use in collaboration commercial products are recognized as product sales when the materials have met all the specifications required for the 
customer's  acceptance  and  title  and  risk  of  loss  have  transferred  to  the  customer.  Following  the  receipts  of  European  marketing  approvals  of 
Roche's Herceptin SC product in August 2013 and MabThera SC product in March 2014 and Baxter's HYQVIA ® product in May 2013, revenue 
from the sales of bulk rHuPH20 for these collaboration products are recognized as product sales. For the years ended December 31, 2014 and 
2013, we recognized $23.5 million and $13.7 million in product sales of bulk rHuPH20 for Roche's collaboration products, respectively. For the 
years ended December 31, 2014 and 2013, we recognized zero  and $1.1 million in  product sales  of bulk  rHuPH20 for Baxter's  collaboration 
product, respectively.

Revenues under Collaborative Agreements  

We  have  license  and  collaboration  agreements  under  which  the  collaborators  obtained  worldwide  rights  for  the  use  of  our  proprietary 
rHuPH20 enzyme in the development and commercialization of the collaborators’ biologic compounds. The collaborative agreements contain 
multiple  elements  including  nonrefundable  payments  at  the  inception  of  the  arrangement,  license  fees,  exclusivity  fees,  payments  based  on 
achievement  of  specified  milestones  designated  in  the  collaborative  agreements,  annual  maintenance  fees,  reimbursements  of  research  and 
development  services,  payments  for  supply  of  bulk  rHuPH20  for  the  collaborator  and/or  royalties  on  sales  of  products  resulting  from 
collaborative  agreements.  We  analyze  each  element  of  our  collaborative  agreements  and  consider  a  variety  of  factors  in  determining  the 
appropriate method of revenue recognition of each element.  

In order to account for the multiple-element arrangements, we identify the deliverables included within the agreement and evaluate which 
deliverables represent units of accounting. Analyzing the arrangement to identify deliverables requires the use of judgment, and each deliverable 
may  be  an  obligation  to  deliver  services,  a  right  or  license  to  use  an  asset,  or  another  performance  obligation.  The  deliverables  under  our 
collaborative agreements include (i) the license to our rHuPH20 technology, (ii) at the collaborator’s request, research and development services 
which are reimbursed at contractually determined rates, and (iii) at the collaborator’s request, supply of bulk rHuPH20 which is reimbursed at 
our cost plus a margin. A delivered item is considered a separate unit of accounting when the delivered item has value to the collaborator on a 
standalone  basis  based  on  the  consideration  of  the  relevant  facts  and  circumstances  for  each  arrangement.  Factors  considered  in  this 
determination  include  the  research  capabilities  of  the  collaborator  and  the  availability  of  research  expertise  in  this  field  in  the  general 
marketplace.  

Arrangement consideration is allocated at the inception of the agreement to all identified units of accounting based on their relative selling 
price. The relative selling price for each deliverable is determined using vendor specific objective evidence (“VSOE”) of selling price or third-
party evidence of selling price if VSOE does not exist. If neither VSOE nor third-party evidence of selling price exists, we use our best estimate 
of the selling price for the deliverable. The amount of allocable arrangement consideration is limited to amounts that are not contingent upon the 
delivery of additional items or meeting other specified performance conditions. The consideration received is allocated among the separate units 
of  accounting, and the applicable revenue recognition criteria are applied  to  each of the separate units. Changes in the allocation of the sales 
price  between  delivered  and  undelivered  elements  can  impact  revenue  recognition  but  do  not  change  the  total  revenue  recognized  under  any 
agreement.  

Nonrefundable upfront license fee payments are recognized upon delivery of the license if facts and circumstances dictate that the license 
has  standalone  value  from  the  undelivered  items,  which  generally  include  research  and  development  services  and  the  manufacture  of  bulk 
rHuPH20, the relative selling price allocation of the license is equal to or exceeds the upfront license fee, persuasive evidence of an arrangement 
exists, our price to the collaborator is fixed or determinable and collectibility is reasonably assured. Upfront license fee payments are deferred if 
facts and circumstances dictate that the license does not have standalone value. The determination of the length of the period over which to defer 
revenue is subject to judgment and estimation and can have an impact on the amount of revenue recognized in a given period.  

The  terms  of  our  collaborative  agreements  provide  for  milestone  payments  upon  achievement  of  certain  development  and  regulatory 
events and/or specified sales volumes of commercialized products by the collaborator. We account for milestone payments in accordance with 
the  provisions  of  ASU  No.  2010-17,  Revenue  Recognition  -  Milestone  Method  .  We  recognize  consideration  that  is  contingent  upon  the 
achievement of a milestone in its entirety as revenue in the period in which the milestone is achieved only if the milestone is substantive in its 
entirety. A milestone is considered substantive when it meets all of the following criteria:  

1.   The consideration is commensurate with either the entity’s performance to achieve the milestone or the enhancement of the value of 

the delivered item(s) as a result of a specific outcome resulting from the entity’s performance to achieve the milestone,  

2.   The consideration relates solely to past performance, and 

3.   The consideration is reasonable relative to all of the deliverables and payment terms within the arrangement. 

A  milestone  is  defined  as  an  event  (i) that  can  only be  achieved  based in  whole or  in  part on  either  the  entity’s performance  or on the 
occurrence  of  a  specific  outcome  resulting  from  the  entity’s  performance,  (ii) for  which  there  is  substantive  uncertainty  at  the  date  the 
arrangement is entered into that the event will be achieved and (iii) that would result in additional payments being due to the vendor.  

F-13  

 
 
 
 
Reimbursements of research and development services are recognized as revenue during the period in which the services are performed as 
long as there is persuasive evidence of an arrangement, the fee is fixed or determinable and collection of the related receivable is reasonably 
assured.  Revenue  from  the  manufacture  of  bulk  rHuPH20  is  recognized  when  the  materials  have  met  all  specifications  required  for  the 
collaborator's acceptance and title and risk of loss have transferred to the collaborator. We do not directly control when any collaborator will 
request  research  and  development  services  or  supply  of  bulk  rHuPH20;  therefore,  we  cannot  predict  when  we  will  recognize  revenues  in 
connection with research and development services and supply of bulk rHuPH20.  

Since we receive royalty reports 60 days after quarter end, royalty revenue from sales of collaboration products by our collaborators will 

be recognized in the quarter following the quarter in which the corresponding sales occurred.  

The collaborative agreements typically provide the collaborators the right to terminate such agreement in whole or on a product-by-product 
or target-by-target basis at any time upon 30 to 90 days prior written notice to us. There are no performance, cancellation, termination or refund 
provisions in any of our collaborative agreements that contain material financial consequences to us.  

Refer to Note 4, “Collaborative Agreements, ” for further discussion on our collaborative arrangements.  

Cost of Product Sales  

Cost of product sales consists primarily of raw materials, third-party manufacturing costs, fill and finish costs, freight costs, internal costs 
and  manufacturing  overhead  associated  with  the  production  of  Hylenex  recombinant  and  bulk  rHuPH20  for  use  in  approved  collaboration 
products. Cost of product sales also consists of the write-down of excess, dated and obsolete inventories and the write-off of any inventories that 
do not meet certain product specifications, if any.  

Prior to European marketing approvals of Roche's collaboration products Herceptin SC in August 2013 and MabThera SC in March 2014, 
and  Baxter's  collaboration  product  HYQVIA  in  May  2013,  all  costs  related  to  the  manufacturing  of  bulk  rHuPH20  for  these  collaboration 
products were charged to research and development expenses in the periods such costs were incurred. Therefore, cost of product sales of these 
bulk rHuPH20 for the year ended December 31, 2013 was materially reduced due to the exclusion of the manufacturing costs that were charged 
to research and development expenses in the periods prior to receiving marketing approvals.  

For the year ended December 31, 2014, cost of product sales of bulk rHuPH20 excluded $1.0 million in manufacturing costs, of which 
$0.9 million and $0.1 million were charged to research and development expenses in the years ended December 31, 2013 and 2012, respectively. 
For the year ended December 31, 2013, cost of product sales of bulk rHuPH20 excluded $10.0 million in manufacturing costs, of which $9.0 
million and $1.0 million were charged to research and development expenses in the years ended December 31, 2013 and 2012, respectively. As 
of  December  31, 2013, bulk rHuPH20 inventory  for  collaboration  products which were  sold in 2014 excluded  $1.0  million in manufacturing 
costs. There was no bulk rHuPH20 for HyQvia on hand as of December 31, 2014 and 2013.  

Research and Development Expenses  

Research and development expenses include salaries and benefits, facilities and other overhead expenses, external clinical trial expenses, 
research  related  manufacturing  services,  contract  services  and  other  outside  expenses.  Research  and  development  expenses  are  charged  to 
operations  as  incurred  when  these  expenditures  relate  to  our  research  and  development  efforts  and  have  no  alternative  future  uses.     After 
receiving  approval  from  the  FDA  or  comparable  regulatory  agencies  in  foreign  countries  for  a  product,  costs  related  to  purchases  and 
manufacturing  of  bulk  rHuPH20  for  product  are  capitalized  as  inventory.  The  manufacturing  costs  of  bulk  rHuPH20  for  the  collaboration 
products,  Herceptin  SC,  MabThera  SC  and  HYQVIA,  incurred  after  the  receipt  of  the  European  marketing  approvals  are  capitalized  as 
inventory.  

In accordance with certain research and development agreements, we are obligated to make certain upfront payments upon execution of 
the agreement. Advance payments, including nonrefundable amounts, for goods or services that will be used or rendered for future research and 
development  activities are deferred and  capitalized.  Such  amounts  will  be  recognized  as an expense as  the related goods are delivered  or  the 
related services are performed or such time when we do not expect the goods to be delivered or services to be performed.  

Milestone payments that we make in connection with in-licensed technology for a particular research and development project that have no 
alternative  future  uses  (in  other  research  and  development  projects  or  otherwise)  and  therefore  no  separate  economic  values  are  expensed  as 
research  and  development  costs  at  the  time  the  costs  are  incurred.  We  have  no  in-licensed  technologies  that  have  alternative  future  uses  in 
research and development projects or otherwise.  

F-14  

 
 
 
 
Clinical Trial Expenses  

Payments in connection with our clinical trials are often made under contracts with multiple contract research organizations that conduct 
and manage clinical trials on our behalf. The financial terms of these agreements are subject to negotiation and vary from contract to contract 
and may result in uneven payment flows. Generally, these agreements set forth the scope of work to be performed at a fixed fee, unit price or on 
a time and materials basis. Payments under these contracts depend on factors such as the successful enrollment or treatment of patients or the 
completion of other clinical trial milestones.  

Expenses  related  to  clinical  trials  are  accrued  based  on  our  estimates  and/or  representations  from  service  providers  regarding  work 
performed, including actual level of patient enrollment, completion of patient studies and progress of the clinical trials. Other incidental costs 
related to patient enrollment or treatment are accrued when reasonably certain. 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 modify our 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. 
Historically,  we  have  had  no  material  changes  in  clinical  trial  expense  accruals  that  had  a  material  impact  on  our  consolidated  results  of 
operations or financial position.  

Share-Based Compensation  

We  record  compensation  expense  associated  with  stock  options  and  other  share-based  awards  in  accordance  with  the  authoritative 
guidance for stock-based compensation. The cost of employee services received in exchange for an award of an equity instrument is measured at 
the grant date, based on the estimated fair value of the award, and is recognized as expense on a straight-line basis, net of estimated forfeitures, 
over  the  requisite  service  period  of  the  award.  Share-based  compensation  expense  recognized  during  the  period  is  based  on  the  value  of  the 
portion of share-based payment awards that is ultimately expected to vest during the period. Share-based compensation expense for an award 
with a performance condition is recognized when the achievement of such performance condition is determined to be probable. If the outcome of 
such  performance  condition  is  not  determined  to  be  probable  or  is  not  met,  no  compensation  expense  is  recognized  and  any  previously 
recognized compensation expense is reversed. As share-based compensation expense recognized is based on awards ultimately expected to vest, 
it has been reduced for estimated forfeitures. The guidance requires forfeitures to be estimated at the time of grant and revised, if necessary, in 
subsequent  periods  if  actual  forfeitures  differ  from  those  estimates.  Pre-vesting  forfeitures  were  estimated  to  be  approximately  10%  for 
employees for the years ended December 31, 2014, 2013 and 2012 based on our historical experience for the years then ended.  

Income Taxes  

We provide for income taxes using the liability method. Under this method, deferred income tax assets and liabilities are determined based 
on the differences between the financial statement carrying amounts of existing assets and liabilities at each year end and their respective tax 
bases and are measured using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Deferred tax 
assets and other tax benefits are recorded when it is more likely than not that the position will be sustained upon audit. Valuation allowances 
have  been  established  to reduce  our  net  deferred tax  assets  to zero ,  as  we believe  that it is more  likely than  not  that such assets will  not  be 
realized.  

Net Loss Per Share  

Basic  net  loss  per  common  share  is  computed  by  dividing  loss  for  the  period  by  the  weighted  average  number  of  common  shares 
outstanding during the period, without consideration for common stock equivalents. Stock options, unvested restricted stock awards (“RSAs”) 
and  unvested  restricted  stock  units  (“RSUs”)  are  considered  common  stock  equivalents  and  are  only  included  in  the  calculation  of  diluted 
earnings  per common  share  when  their  effect  is dilutive.  Because  of our net  loss, outstanding  stock  options,  outstanding  RSUs  and  unvested 
RSAs totaling approximately 8,405,903 , 8,070,141 and 7,444,333 were excluded from the calculation of diluted net loss per common share for 
the years ended December 31, 2014, 2013 and 2012 , respectively, because their effect was anti-dilutive. Since the performance conditions for 
performance restricted  stock  units (“PRSUs”) were  not satisfied at December 31, 2014, such securities are excluded from potentially dilutive 
securities.

Segment Information  

We operate our business in one segment, which includes all activities related to the research, development and commercialization of our 
proprietary  enzymes.  This  segment  also  includes  revenues  and  expenses  related  to  (i) research  and  development  and  API  manufacturing 
activities  conducted  under  our  collaborative  agreements  with  third  parties  and  (ii) product  sales  of  Hylenex  recombinant.  The  chief  operating 
decision-maker reviews the operating results on an aggregate basis and manages the operations as a single operating segment.  

Pending Adoption of Recent Accounting Pronouncements  

In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-15,  Presentation of 
Financial Statements — Going Concern (“ASU 2014-15”). The provisions of ASU 2014-15 provide that in connection with preparing financial 
statements  for  each  annual  and  interim  reporting  period,  an  entity's  management  should  evaluate  whether  there  are  conditions  or  events, 
considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that 
the financial statements are issued (or within one year after the date that the financial statements are available to be issued when applicable). 
ASU 2014-15 is effective for the annual reporting period ending after December 15, 2016, and for annual and interim periods thereafter. Early 
adoption  is  permitted.  The  adoption  of  ASU  2014-15  will  not  have  a  material  impact  on  our  consolidated  financial  position  or  results  of 
operations.  

In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). 
ASU 2014-09 will eliminate transaction-specific and industry-specific revenue recognition guidance under current GAAP and replace it with a 
principle-based approach for determining revenue recognition. ASU 2014-09 will require that companies recognize revenue based on the value 
of  transferred  goods  or  services  as  they  occur in  the  contract.  ASU  2014-09  also  will  require  additional  disclosure about  the  nature,  amount, 
timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and 
assets  recognized  from  costs  incurred  to  obtain  or  fulfill  a  contract.  ASU  2014-09  is  effective  for  annual  reporting  periods  beginning  after 
December  15,  2016.  Early  application  is  not  permitted.  Entities  can  transition  to  the  standard  either  retrospectively  or  as  a  cumulative-effect 
adjustment as of the date of adoption. We have not yet selected a transition method and we are currently evaluating the effect that the updated 
standard will have on our consolidated financial statements and related disclosures.  

In July 2013, the FASB issued Accounting Standards Update No. 2013-11, Income Taxes (Topic 740), Presentation of an Unrecognized 
Tax  Benefit  When  a  Net  Operating  Loss  Carryforward,  a  Similar  Tax  Loss,  or  a  Tax  Credit  Carryforward  Exists  (“ASU  2013-11”).  The 
provisions of ASU 2013-11 require entities to present unrecognized tax benefits as a decrease in a net operating loss, similar tax loss or tax credit 
carryforward if certain criteria are met. The determination of whether a deferred tax asset is available is based on the unrecognized tax benefit 
and the deferred tax asset that exists at the reporting date and presumes disallowance of the tax position at the reporting date. The guidance will 
eliminate the diversity in practice in the presentation of unrecognized tax benefits but will not alter the way in which entities assess deferred tax 
assets for realizability. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 
15,  2014.  The  amendments  should  be  applied  prospectively  to  unrecognized  tax  benefits  that  exist  at  the  effective  date.  Early  adoption  is 
permitted. The adoption of ASU 2013-11 will not have a material impact on our consolidated financial position or results of operations.

As  of  December 31,  2014  ,  all  of  our  available-for-sale  marketable  securities  were  scheduled  to  mature  within  the  next  twelve  months. 
There were $57.3 million of available-for-sale securities that matured during the year ended December 31, 2014 . There were no realized gains 
or losses for the year ended December 31, 2014 and 2013. As of December 31, 2014 , we had 14 available-for-sale marketable securities in a 
gross  unrealized  loss  position,  all  of  which  had  been  in  such  position  for  less  than  twelve  months.  Based  on  our  review  of  these  marketable 
securities, we believe we had no other-than-temporary impairments on these securities as of December 31, 2014 because we do not intend to sell 
these securities and it is not more likely than not that we will be required to sell these securities before the recovery of their amortized cost basis.  

4.   Collaborative Agreements 

Roche Collaboration  

In December 2006, we and Roche entered into a license and collaborative agreement under which Roche obtained a worldwide, exclusive 
license to develop and commercialize product combinations of our patented rHuPH20 enzyme and up to thirteen Roche target compounds (the 
“Roche Collaboration”). As of December 31, 2014 , Roche had elected a  total of five exclusive targets and retains the option to develop and 
commercialize  rHuPH20  with  three  additional  targets,  provided  that  Roche  continues  to  pay  annual  maintenance  fees  to  us.  Roche  received 
European  marketing  approval  in  August  2013  for  its  collaboration  product,  Herceptin  SC,  for  the  treatment  of  patients  with  HER2-positive 
breast cancer and launched Herceptin SC in the European Union (“EU”) in September 2013.  

In  March  2014,  Roche  received  European  marketing  approval  for  its  collaboration  product,  MabThera  SC,  for  the  treatment  of  patients 
with common forms of non-Hodgkin lymphoma (“NHL”). In June 2014, Roche launched MabThera SC in the EU which triggered a $5.0 million 
sales-based payment to us for the achievement of the first commercial sale pursuant to the terms of the Roche Collaboration.  

Roche assumes all development, manufacturing, clinical, regulatory, sales and marketing costs under the Roche Collaboration, while we 
are responsible for the supply of bulk rHuPH20. We are entitled to receive reimbursements for providing research and development services and 
bulk rHuPH20 to Roche at its request.

Under the terms of the Roche Collaboration, Roche pays us a royalty on each product commercialized under the agreement consisting of a 
mid-single  digit  percent  of  the  net  sales  of  such  product.  Unless  terminated  earlier  in  accordance  with  its  terms,  the  Roche  Collaboration 
continues  in  effect  until  the  expiration  of  Roche's  obligation  to  pay  royalties.  Roche  has  the  obligation  to  pay  royalties  with  respect  to  each 
product in each country, during the period equal to the longer of: (a) the duration of any valid claim of our patents covering rHuPH20 or other 
specified patents developed under the collaboration which valid claim covers the product in such country or (b) ten years following the date of 
the first commercial sale of such product in such country.  

As  of  December 31,  2014  ,  we  have  received  $78.3  million  ,  excluding  royalties  and  reimbursements  for  providing  research  and 
development  services  and  supplying  bulk  rHuPH20,  from  Roche.  The  amounts  received  consisted  of  the  $20.0  million  upfront  license  fee 
payment for the application of rHuPH20 to the initial three Roche exclusive targets, $22.3 million in connection with Roche's election of two 
additional  exclusive  targets  and  annual  license  maintenance  fees  for  the  right  to  designate  the  remaining  targets  as  exclusive  targets,  $13.0 
million in clinical development milestone payments, $8.0 million in regulatory milestone payments and $15.0 million in sales-based payments. 
Due to our continuing involvement obligations (for example, support activities associated with rHuPH20), revenues from the upfront payment, 
exclusive designation fees, annual license maintenance fees and sales-based payment were deferred and are being amortized over the remaining 
term of the Roche Collaboration.  

For  the years  ended  December 31,  2014,  2013  and  2012  ,  we  recognized  approximately  $8.1  million  , $4.6  million ,  and  $2.0 million  , 
respectively, of Roche deferred revenues as revenues under collaborative agreements. In addition, for the years ended December 31, 2014, 2013 
and 2012, we recognized approximately $2.0 million , $1.3 million and $1.4 million , respectively, of deferred bulk rHuPH20 sales revenue as 
product sales revenue. Total Roche deferred revenues was approximately $42.7 million and $41.6 million as of December 31, 2014 and 2013, 
respectively. For the year ended December 31, 2012, we recognized $8.0 million as revenues under collaborative agreements in accordance with 
the Milestone  Method  related  to  the achievement  of certain regulatory milestones pursuant  to  the terms  of the  Roche  Collaboration. No  such 
revenues were recognized for the years ended December 31, 2014 and 2013.  

Gammagard Collaboration  

In  September  2007,  we  entered  into  a  license  and  collaborative  agreement  with  Baxter,  under  which  Baxter  obtained  a  worldwide, 
exclusive  license  to  develop  and  commercialize  HYQVIA,  a  combination  of  Baxter's  current  product  GAMMAGARD  LIQUID  ™  and  our 
patented rHuPH20 enzyme (the “Baxter Collaboration”). In May 2013, the European Commission granted Baxter marketing authorization in all 
EU Member States for the use of HYQVIA (solution for subcutaneous use), a combination of GAMMAGARD LIQUID and rHuPH20 in dual 
vial units, as replacement therapy for adult patients with primary and secondary immunodeficiencies. Baxter launched HYQVIA in the first EU 
country in July 2013 and in additional EU countries in the second half of 2013 and in 2014. The FDA approved HYQVIA for treatment of adult 
patients with primary immunodeficiency in September 2014. In October 2014, Baxter announced the launch and first shipments of HYQVIA in 
the U.S.  

The Baxter Collaboration is applicable to both kit and formulation combinations. Baxter assumes all development, manufacturing, clinical, 
regulatory, sales and marketing costs under the Baxter Collaboration, while we are responsible for the supply of bulk rHuPH20. We perform 
research and development activities and  supply bulk  rHuPH20 at the request  of Baxter,  and are reimbursed by Baxter under the terms of  the 
Baxter Collaboration. In addition, Baxter has certain product development and commercialization obligations in major markets identified in the 
Baxter Collaboration.  

Unless  terminated  earlier  in  accordance  with  its  terms,  the  Baxter  Collaboration  continues  in  effect  until  the  expiration  of  Baxter's 
obligation to pay royalties. Baxter has the obligation to pay royalties, with respect to each product in each country, during the period equal to the 
longer  of:  (a)  the  duration  of  any  valid  claim  of  our  patents  covering  rHuPH20  or  other  specified  patents  developed  under  the  collaboration 
which valid claim covers the product in such country or (b) ten years following the date of the first commercial sale of such product in such 
country.  

F-18  

 
 
 
 
As  of  December 31,  2014  ,  we  have  received  $17.0  million  under  the  Gammagard  Collaboration,  excluding  royalties.  The  amounts 
received consisted of the $10.0 million upfront license fee payment, a $3.0 million regulatory milestone payment and a $4.0 million sales-based 
payment. Baxter pays us a royalty on HYQVIA consisting of a mid-single digit percent of the net sales of such product. Due to our continuing 
involvement obligations (for example, support activities associated with rHuPH20 enzyme), the upfront and sales-based payments were deferred 
and are being recognized over the term of the Baxter Collaboration. We recognized revenue from the upfront and sales-based payments in the 
amount of approximately $0.8  million  , $0.6  million  and  $0.5 million for the years  ended December 31, 2014, 2013  and 2012  ,  respectively. 
Deferred revenue relating to the upfront and sales-based payments under the Gammagard Collaboration was approximately $10.9 million and 
$10.5 million as of December 31, 2014 and 2013 , respectively.  

Other Collaborations  

In December 2014, we and Janssen entered into a collaboration and license agreement, under which Janssen has the worldwide license to 
develop and commercialize products combining our patented rHuPH20 enzyme with Janssen proprietary biologics directed at up to five targets 
(the “Janssen Collaboration”). Targets may be selected on an exclusive or non-exclusive basis. As of December 31, 2014, we have received a 
$15.0  million  payment  for  the  license  fee  of  one  specified  exclusive  target  and  the  right  to  elect  four  additional  targets  in  the  future  upon 
payment of additional fees. Unless terminated earlier in accordance with its terms, the Janssen Collaboration continues in effect until the later of 
(i)  expiration  of  the  last  to  expire  of  the  valid  claims  of  our  patents  covering  rHuPH20  or  other  specified  patents  developed  under  the 
collaboration which valid claim covers a product developed under the collaboration, and (ii) expiration of the last to expire royalty term for a 
product  developed  under  the  collaboration.  The  royalty  term  of  a  product  developed  under  the  Janssen  Collaboration,  with  respect  to  each 
country, consists of the period equal to the longer of: (a) the duration of any valid claim of our patents covering rHuPH20 or other specified 
patents developed under the collaboration which valid claim covers the product in such country or (b) ten years following the date of the first 
commercial sale of such product in such country. Janssen may terminate the agreement prior to expiration for any reason in its entirety or on a 
target-by-target basis upon 90 days prior written notice to us. Upon any such termination, the license granted to Janssen (in total or with respect 
to the terminated target, as applicable) will terminate, provided, however, that in the event of expiration of the agreement, the licenses granted 
will become perpetual, non-exclusive and fully paid-up.  

In  December  2012,  we  and  Pfizer  entered  into  a  collaboration  and  license  agreement,  under  which  Pfizer  has  the  worldwide  license  to 
develop and commercialize products combining our patented rHuPH20 enzyme with Pfizer proprietary biologics directed at up to six targets (the 
“Pfizer Collaboration”). Targets  may be selected on  an  exclusive  or non-exclusive basis. As  of December 31, 2014 , we  have received $11.0 
million in upfront and license fee payments for the licenses to four specified exclusive targets and two additional targets which Pfizer has the 
right  to  elect  in  the  future  upon  payment  of  additional  fees.  Unless  terminated  earlier  in  accordance  with  its  terms,  the  Pfizer  Collaboration 
continues in effect until the later of (i) expiration of the last to expire of the valid claims of our patents covering rHuPH20 or other specified 
patents developed under the collaboration which valid claim covers a product developed under the collaboration, and (ii) expiration of the last to 
expire royalty term for a product developed under the collaboration. The royalty term of a product developed under the Pfizer Collaboration, 
with respect to each country, consists of the period equal to the longer of: (a) the duration of any valid claim of our patents covering rHuPH20 or 
other specified patents developed under the collaboration which valid claim covers the product in such country or (b) ten years following the 
date of the first commercial sale of such product in such country. Pfizer may terminate the agreement prior to expiration for any reason in its 
entirety or on a target-by-target basis upon 30 days prior written notice to us. Upon any such termination, the license granted to Pfizer (in total or 
with  respect  to  the  terminated  target,  as  applicable)  will  terminate,  provided,  however,  that  in  the  event  of  expiration  of  the  agreement,  the 
licenses granted will become perpetual, non-exclusive and fully paid-up.  

F-19  

 
 
 
 
At the inception of the Pfizer and Janssen arrangements, we identified the deliverables in each arrangement to include the license, research 
and development services and supply of bulk rHuPH20. We have determined that the license, research and development services and supply of 
bulk rHuPH20 individually represent separate units of accounting, because each deliverable has standalone value. The estimated selling prices 
for  these  units  of  accounting  were  determined  based  on  market  conditions,  the  terms  of  comparable  collaborative  arrangements  for  similar 
technology in the pharmaceutical and biotech industry and entity-specific factors such as the terms of our previous collaborative agreements, our 
pricing  practices  and  pricing  objectives.  The  arrangement  consideration  was  allocated  to  the  deliverables  based  on  the  relative  selling  price 
method and the nature of the research and development services to be performed for the collaborator.  

The  amount  allocable  to  the  delivered  unit  or  units  of  accounting  is  limited  to  the  amount  that  is  not  contingent  upon  the  delivery  of 
additional  items  or  meeting  other  specified  performance  conditions  (the  noncontingent  amount).  As  such,  we  excluded  from  the  allocable 
arrangement consideration the milestone payments, annual exclusivity fees and royalties regardless of the probability of receipt. Based on the 
results  of  our  analysis,  we  allocated  the  $11.0  million  license  fees  from  Pfizer  and  the  $15.0  million  upfront  license  fee  from  Janssen  to  the 
license  fee  deliverable  under  each  of  the  arrangements.  We  determined  that  the  upfront  payments  were  earned  upon  the  granting  of  the 
worldwide, exclusive right to our technology to the collaborators in these arrangements. As a result, we recognized the $11.0 million license fees 
under  the  Pfizer  Collaboration  and  the  $15.0  million  upfront  license  fee  under  the  Janssen  Collaboration  as  revenues  under  collaborative 
agreements  in the period  when  such  license  fees were  earned. There  were no  revenues recognized related  to  milestone payments under these 
collaborations for the years ended December 31, 2014, 2013 and 2012.  

The  collaborators  are  each  solely  responsible  for  the  development,  manufacturing  and  marketing  of  any  products  resulting  from  their 
respective  collaborations.  We  are  entitled  to  receive  payments  for  research  and  development  services  and  supply  of  rHuPH20  API  to  these 
collaborators  if  requested  by  such  collaborator.  We  recognize  amounts  allocated  to  research  and  development  services  as  revenues  under 
collaborative  agreements  as  the  related  services  are  performed.  We  recognize  amounts  allocated  to  the  sales  of  API  as  revenues  under 
collaborative  agreements  when  such  API  has  met  all  required  specifications  by  the  collaborators  and  the  related  title  and  risk  of  loss  and 
damages have passed to the collaborators. We cannot predict the timing of delivery of research and development services and API as they are at 
the collaborators' requests.  

In  May  2011  and  June  2011,  we  entered  into  collaboration  and  license  agreements  with  ViroPharma  Incorporated  and  Intrexon 

Corporation, respectively. These collaboration agreements were terminated effective May 2014 .  

Pursuant to the terms of our collaboration agreements with Roche and Pfizer, certain future payments meet the definition of a milestone in 
accordance with the Milestone Method of Accounting. We are entitled to receive additional milestone payments for the successful development 
of the elected targets in the aggregate of up to approximately $55.0 million upon achievement of specified clinical development milestone events 
and up to approximately $12.0 million upon achievement of specified regulatory milestone events in connection with specified regulatory filings 
and receipt of marketing approvals.

In December 2013, we entered into an Amended and Restated Loan and Security Agreement (the “Loan Agreement”) with Oxford Finance 
LLC  (“Oxford”)  and  Silicon  Valley  Bank  (“SVB”)  (collectively,  the  “Lenders”),  amending  and  restating  in  its  entirety  our  original  loan 
agreement with the Lenders, dated December 2012. The Loan Agreement provided for an additional $20 million principal amount of new term 
loan, bringing the total term loan balance to $50 million . The proceeds are to be used for working capital and general business requirements. 
The amended term loan facility matures on January 1, 2018 .  

In  January  2015,  we  entered  into  the  second  amendment  to  the  Loan  Agreement  with  the  Lenders,  amending  and  restating  the  loan 
repayment  schedules  of  the  Loan  Agreement.  The  amended  and  restated  term  loan  repayment  schedule  provides  for  interest  only  payments 
through  January  2016  ,  followed  by  consecutive  equal  monthly  payments  of  principal  and  interest  in  arrears  starting  in  February  2016  and 
continuing through the previously established maturity date of January 2018. Consistent with the original loan, the Loan Agreement provides for 
a 7.55% interest rate on the term loan and a final interest payment equal to 8.5% of the original principal amount, or $4.25 million , which is due 
when the term loan becomes due or upon the prepayment of the facility. We have the option to prepay the outstanding balance of the term loan in 
full, subject to a prepayment fee of 1% to 3% depending upon when the prepayment occurs.  

In connection with the term loan, the debt offering costs have been recorded as a debt discount in our consolidated balance sheets which, 
together with the final payment and fixed interest rate payments, are being amortized and recorded as interest expense throughout the life of the 
term loan using the effective interest rate method.  

The amended term loan is secured by substantially all of the assets of the Company and our subsidiary, Halozyme, Inc., except that the 
collateral  does  not  include  any  equity  interests  in  Halozyme,  Inc.,  any  intellectual  property  (including  all  licensing,  collaboration  and  similar 
agreements  relating  thereto),  and  certain  other  excluded  assets.  The  Loan  Agreement  contains  customary  representations,  warranties  and 
covenants by us, which covenants limit our ability to convey, sell, lease, transfer, assign or otherwise dispose of certain of our assets; engage in 
any business other than the businesses currently engaged in by us or reasonably related thereto; liquidate or dissolve; make certain management 
changes; undergo certain change of control events; create, incur, assume, or be liable with respect to certain indebtedness; grant certain liens; pay 
dividends  and  make  certain  other  restricted  payments;  make  certain  investments;  make  payments  on  any  subordinated  debt;  and  enter  into 
transactions with any of our affiliates outside of the ordinary course of business or permit our subsidiaries to do the same. In addition, subject to 
certain exceptions, we are required to maintain with SVB our primary deposit accounts, securities accounts and commodities, and to do the same 
for our domestic subsidiary.  

The Loan Agreement also contains customary indemnification obligations and customary events of default, including, among other things, 
our failure to fulfill certain of our obligations under the Loan Agreement and the occurrence of a material adverse change which is defined as a 
material adverse change in our business, operations, or condition (financial or otherwise), a material impairment of the prospect of repayment of 
any portion of the loan, or a material impairment in the perfection or priority of lender's lien in the collateral or in the value of such collateral. In 
the event of default by us under the Loan Agreement, the Lenders would  

F-22  

 
 
 
 
   
  
  
  
  
  
be entitled to exercise their remedies thereunder, including the right to accelerate the debt, upon which we may be required to repay all amounts 
then outstanding under the Loan Agreement, which could harm our financial condition.  

 As  of  December 31,  2014  ,  we  were  in  compliance  with  all  material  covenants  under  the  Loan  Agreement  and  there  was  no  material 

adverse change in our business, operations or financial condition.

7.   Stockholders’ Equity (Deficit) 

During 2014, we issued an aggregate of 1,432,206 shares of common stock, in connection with the exercises of stock options for cash in 
the  aggregate  amount  of  approximately  $7.8  million  .  In  addition,  we  issued  789,345  shares  of  common  stock,  net  of  RSAs  canceled,  in 
connection with the grants of RSAs and 120,043 shares of common stock upon vesting of certain RSUs. The RSU holders surrendered 74,325 
RSUs to pay for minimum withholding taxes totaling approximately $1.0 million .  

In  February 2014,  we  completed  an  underwritten  public  offering  and  issued   8,846,153   shares  of  common  stock,  including   1,153,846 
 shares  sold  pursuant  to  the  full  exercise  of  an  over-allotment  option  granted  to  the  underwriters.  All  of  the  shares  were  offered  at  a  public 
offering price of  $13.00  per share, generating approximately  $107.7 million in net proceeds.  

During 2013, we issued an aggregate of 1,270,362 shares of common stock in connection with the exercises of stock options for cash in the 
aggregate amount of approximately $5.5 million . In addition, we issued 461,729 shares of common stock, net of RSAs canceled, in connection 
with the grants of RSAs and 92,201 shares of common stock upon vesting of certain RSUs. The RSU holders surrendered 61,923 RSUs to pay 
for minimum withholding taxes totaling approximately $0.4 million .  

In February 2012, we completed an underwritten public offering and issued 7,820,000 shares of common stock, including 1,020,000 shares 
sold pursuant to the full exercise of an over-allotment option granted to the underwriter. All of the shares were offered at a public offering price 
of $10.61 per share, generating approximately $81.5 million in net proceeds. Of the 7,820,000 shares of common stock sold, Randal J. Kirk, a 
member of our board of directors, through his affiliates, purchased 1,360,000 shares of common stock in this offering at the public offering price 
of $10.61 per share for a total of approximately $14.4 million .

8.   Equity Incentive Plans 

We  currently  grant  stock  options,  restricted  stock  awards  and  restricted  stock  units  under  the  Amended  and  Restated  2011  Stock  Plan 
("2011 Stock Plan"). In May 2013, our stockholders approved the Amended and Restated 2011 Stock Plan, which provides for the grant of up to 
12.5  million  shares  of  common  stock  (subject  to  certain  limitations  as  described  in  the  Amended  and  Restated  2011  Stock  Plan)  to  selected 
employees, consultants and non-employee members of our Board of Directors (“Outside Directors”) as stock options, stock appreciation rights, 
restricted stock awards, restricted stock unit awards and performance awards. The 2011 Stock Plan was approved by the stockholders. Awards 
are subject to terms and conditions established by the Compensation Committee of our Board of Directors. During the year ended December 31, 
2014 , we granted share-based awards under the 2011 Stock Plan. At December 31, 2014 , 7,247,452 shares were subject to outstanding awards 
and 4,681,212 shares were available for future grants of  share-based awards. At the present time, management intends to issue new common 
shares upon the exercise of stock options, issuance of restricted stock awards and settlement of restricted stock units.  

Total share-based compensation expense related to share-based awards was comprised of the following (in thousands):

Cash  flows  resulting  from  tax  deductions  in  excess  of  the  cumulative  compensation  cost  recognized  for  options  exercised  (excess  tax 
benefits)  are  classified  as  cash  inflows  provided  by  financing  activities  and  cash  outflows  used  in  operating  activities.  Due  to  our  net  loss 
position, no tax benefits have been recognized in the consolidated statements of cash flows.  

Stock Options.  Options granted under the Plans must have an exercise price equal to at least 100% of the fair market value of our common 
stock on the date of grant. The options will generally have a maximum contractual term of ten years and vest at the rate of one-fourth of the 
shares  on  the  first  anniversary  of  the  date  of  grant  and  1/48  of  the  shares  monthly  thereafter.  Certain  option  awards  provide  for  accelerated 
vesting if there is a change in control (as defined in the Plans).

The weighted average grant-date fair values of options granted during the years ended December 31, 2014, 2013 and 2012 were $8.13 per 
share, $4.40  per  share  and $5.63 per share,  respectively. The intrinsic  value of options exercised during  the years ended December 31, 2014, 
2013 and 2012 was approximately $8.1 million , $8.3 million and $2.9 million , respectively. Cash received from stock option exercises for the 
years ended December 31, 2014, 2013 and 2012 was approximately $7.8 million , $5.5 million and $2.0 million , respectively.  

The  fair  value  of  each  option  award  is  estimated  on  the  date  of  grant  using  the  Black-Scholes-Merton  option  pricing  model  (“Black-
Scholes model”) that uses the assumptions noted in the following table. Expected volatility is based on historical volatility of our common stock. 
The expected term of options granted is based on analyses of historical employee termination rates and option exercises. The risk-free interest 
rate  is  based  on  the  U.S.  Treasury  yield  for  a  period  consistent  with  the  expected  term  of  the  option  in  effect  at  the  time  of  the  grant.  The 
dividend yield assumption is based on the expectation of no future dividend payments by us. Assumptions used in the Black-Scholes model were 
as follows:

Average expected term (in years)  
Risk-free interest rate

Restricted Stock Awards .  Restricted stock awards are grants that entitle the holder to acquire shares of our common stock at zero or a 
fixed price, which is typically nominal. The shares covered by a restricted stock award cannot be sold, pledged, or otherwise disposed of until the 
award vests and any unvested shares may be reacquired by us for the original purchase price following the awardee’s termination of service. The 
restricted  stock  awards  will  generally  vest  at  the  rate  of  one-fourth  of  the  shares  on  each  anniversary  of  the  date  of  grant.  Annual  grants  of 
restricted stock awards to Outside Directors typically vest in full the first day the awardee may trade our stock in compliance with our insider 
trading policy following the date immediately preceding the first annual meeting of stockholders following the grant date.  

The following table summarizes our restricted stock award activity during the years ended December 31, 2014, 2013 and 2012 :

The estimated fair value of the restricted stock units was based on the market value of our common stock on the date of grant. The total 
intrinsic value of restricted stock units vested during the years ended December 31, 2014, 2013 and 2012 was approximately $2.6 million , $1.1 
million and $0.9 million , respectively. We recognized approximately $2.0 million , $1.8 million and $1.5 million of share-based compensation 
expense related to the restricted stock units for the years ended December 31, 2014, 2013 and 2012 , respectively.  

In  July  2014,  we  granted  540,742  PRSUs  to  our  executive  officers,  which  are  not  included  in  the  table  above.  For  the  year  ended 
December 31,  2014  ,  there  were  109,504  PRSUs  forfeited.  As  of  December  31,  2014,  the  aggregate  intrinsic  value  of  the  431,238  PRSUs 
outstanding  was  $4.2  million  .  For  the  year  ended  December 31,  2014  ,  there  was  no  expense  recognized  related  to  the  PRSUs,  as  the 
achievement of the performance conditions was not determined to be probable.  

9.   Commitments and Contingencies 

Operating Leases  

Our  administrative  offices  and  research  facilities  are  located  in  San Diego,  California.  We  lease  an  aggregate  of  approximately  76,000 
square  feet  of  office  and  research  space  in  four  buildings.  The  leases  commenced  in  June  2011  and  November  2013  and  continue  through 
January 2018 . The leases are subject to approximately 2.5% to 3.0% annual increases throughout the terms of the leases. We also pay a pro rata 
share of operating costs, insurance costs, utilities and real property taxes.  

We  received  incentives  under  the  leases,  including  tenant  improvement  allowances  and  reduced  or  free  rent,  which  the  unamortized 

deferred rent balances associated with these incentives was $1.0 million as of December 31, 2014 and 2013.  

Additionally, we lease certain office equipment under operating leases. Total rent expense was approximately $1.9 million , $1.7 million 

and $1.6 million for the years ended December 31, 2014, 2013 and 2012 , respectively.

In  order to scale  up the production  of bulk  rHuPH20 and to identify another manufacturer that would  help meet anticipated production 
obligations  arising  from  our  proprietary  programs  and  our  collaborations,  we  entered  into  a  Technology  Transfer  Agreement  and  a  Clinical 
Supply  Agreement  with  Cook  Pharmica  LLC  (“Cook”).  The  technology  transfer  was  completed  in  2008.  In  2009,  multiple  batches  of  bulk 
rHuPH20 were produced to support planned future clinical studies.  

In  March  2010,  we  entered  into  a  Commercial  Supply  Agreement  with  Cook  (the  “Cook  Commercial  Supply  Agreement”).  Under  the 
terms of the Cook Commercial Supply Agreement, Cook will manufacture certain batches of bulk rHuPH20 that will be used for commercial 
supply of certain products and product candidates. Under the terms of the Cook Commercial Supply Agreement, we are committed to certain 
minimum annual purchases of bulk rHuPH20 equal to four quarters of forecasted supply. At December 31, 2014 , we had no minimum purchase 
obligation in connection with the Cook Commercial Supply Agreement.  

In  March  2010,  we  amended  our  Commercial  Supply  Agreement  (the  “March  2010  Avid  Amendment”)  with  Avid  Bioservices,  Inc. 
(“Avid”)  which  was  originally  entered  into  in  February  2005  and  amended  in  December  2006.  Under  the  terms  of  the  March  2010  Avid 
Amendment, we are committed to certain minimum annual purchases of bulk rHuPH20 equal to three quarters of forecasted supply. In addition, 
Avid has the right to manufacture and supply a certain percentage of bulk rHuPH20 that will be used in Hylenex recombinant. At December 31, 
2014 , we had no minimum purchase obligations with this agreement.  

In March 2010, we entered into a second Commercial Supply Agreement with Avid (the “Avid Commercial Supply Agreement”). Under 
the terms of the Avid Commercial Supply Agreement, we are committed to certain minimum annual purchases of bulk rHuPH20 equal to three 
quarters of forecasted supply. In addition, Avid has the right to manufacture and supply a certain percentage of bulk rHuPH20 that will be used 
in the collaboration products. At December 31, 2014 , we had a $9.6 million minimum purchase obligation in connection with this agreement.  

In June 2011, we entered into a commercial manufacturing and supply agreement with Baxter, under which Baxter provides the final fill 
and finishing steps in the production process of Hylenex recombinant for a limited period of time. The initial term of the agreement with Baxter 
was  extended  to  December  31,  2015,  subject  to  further  extensions  in  accordance  with  the  terms  and  conditions  of  the  agreement.  At 
December 31, 2014 , we had a minimum purchase obligation in connection with this agreement of approximately $1.7 million .    

In June 2011, we entered into a services agreement with another third party manufacturer for the technology transfer and manufacture of 

Hylenex recombinant. At December 31, 2014 , we had a $1.2 million minimum purchase obligation in connection with this agreement.  

Contingencies  

We have entered into an in-licensing agreement with a research organization, which is cancelable at our option with 90 days written notice. 
Under the terms of this agreement, we have received license to know-how and technology claimed, in certain patents or patent applications. We 
are required to pay fees, milestones and/or royalties on future sales of products employing the technology or falling under claims of a patent, and 
some of the agreements require minimum royalty payments. We continually reassess the value of the license agreement. If the in-licensed and 
research candidate is successfully developed, we may be required to pay milestone payments of approximately $9.3 million over the life of this 
agreement  in  addition  to  royalties  on  sales  of  the  affected  products.  Due  to  the  uncertainties  of  the  development  process,  the  timing  and 
probability of the milestone and royalty payments cannot be accurately estimated.  

F-28  

 
 
 
 
  
  
  
  
Legal Contingencies  

From time to time, we may be involved in disputes, including litigation, relating to claims arising out of operations in the normal course of 
our business. Any of these claims could subject us to costly legal expenses and, while we generally believe that we have adequate insurance to 
cover many different types of liabilities, our insurance carriers may deny coverage or our policy limits may be inadequate to fully satisfy any 
damage awards or settlements. If this were to happen, the payment of any such awards could have a material adverse effect on our consolidated 
results of operations and financial position. Additionally, any such claims, whether or not successful, could damage our reputation and business. 
We currently are not a party to any legal proceedings, the adverse outcome of which, in management’s opinion, individually or in the aggregate, 
would have a material adverse effect on our consolidated results of operations or financial position.  

10.   Income Taxes 

Significant  components  of  our  net  deferred  tax  assets  at  December  31,  2014  and  2013  are  shown  below  (in  thousands).  A  valuation 
allowance of $179.0 million and $162.0 million has been established to offset the net deferred tax assets as of December 31, 2014 and 2013 , 
respectively, as realization of such assets is uncertain.

At December 31, 2014 , we had federal and California tax net operating loss carryforwards of approximately $341.9 million and $307.9 
million  ,  respectively.  Included  in  these  amounts  are  federal  and  California  net  operating  losses  of  approximately  $34.3  million  and  $32.8 
million , respectively, attributable to stock option, RSA and RSU deductions for which the tax benefit will be credited to equity when realized. 
The federal and California tax loss carryforwards will begin to expire in 2018 and 2015 , respectively, unless previously utilized.  

At  December 31,  2014  ,  we  also  had  federal  and  California  research  and  development  tax  credit  carryforwards  of  approximately  $26.1 
million and $12.2 million , respectively. The federal research and development tax credits will begin to expire in 2024 unless previously utilized. 
The California research and development tax credits will carryforward indefinitely until utilized.  

Pursuant to Internal Revenue Code Section 382, the annual use of the net operating loss carryforwards and research and development tax 
credits  could  be  limited  by  any  greater  than  50%  ownership  change  during  any  three-year  testing  period.  As  a  result  of  any  such  ownership 
change, portions of our net operating loss carryforwards and research and development tax credits are subject to annual limitations. We recently 
completed an updated Section 382 analysis regarding the limitation of the net operating losses and research and development credits as of June 
30,  2014.  Based  upon  the  analysis,  we  determined  that  ownership  changes  occurred  in  prior  years.  However,  the  annual  limitations  on  net 
operating  loss  and  research  and  development  tax  credit  carryforwards  will  not  have  a  material  impact  on  the  future  utilization  of  such 
carryforwards.  

At December 31, 2014 and 2013 , our unrecognized income tax benefits and uncertain tax positions were not material and would not, if 
recognized, affect the effective tax rate. Interest and/or penalties related to uncertain income tax positions are recognized by us as a component 
of income tax expense. For the years ended December 31, 2014, 2013 and 2012 , we recognized no interest or penalties.  

We  do  not  provide  for  U.S.  income  taxes  on  the  undistributed  earnings  of  our  foreign  subsidiary  as  it  is  our  intention  to  utilize  those 
earnings in the foreign operations for an indefinite period of time. At December 31, 2014, there were no undistributed earnings in the foreign 
subsidiary.  

We are  subject to  taxation  in  the  U.S.  and  in various state  and  foreign  jurisdictions.  Our  tax years  for  1998  and  forward are  subject to 
examination by the U.S. and California tax authorities due to the carryforward of unutilized net operating losses and research and development 
credits.  

11.   Employee Savings Plan 

We  have  an  employee  savings  plan  pursuant  to  Section 401(k)  of  the  Internal  Revenue  Code. All  employees  are  eligible  to  participate, 
provided they meet the requirements of the plan. We are not required to make matching contributions under the plan. However, we voluntarily 
contributed  to  the  plan  approximately  $0.7  million  ,  $0.6  million  and  $0.5  million  for  the  years  ended  December 31,  2014,  2013  and  2012  , 
respectively.  

12.   Related Party Transactions 

In June 2011, we and Intrexon entered into the Intrexon Collaboration, under which Intrexon obtained a worldwide exclusive license for 
the use of rHuPH20 enzyme in the development of a subcutaneous injectable formulation of Intrexon’s recombinant human alpha 1-antitrypsin 
(rHuA1AT). The Intrexon Collaboration was terminated in May 2014 . Intrexon’s chief executive officer and chairman of its board of directors, 
Randal J. Kirk, is also a member of our Board of Directors. The collaborative arrangement with Intrexon was reviewed and approved by our 
Board  of  Directors  in  accordance  with  our  related  party  transaction  policy.  For  the  years  ended  December 31,  2014,  2013  and  2012  ,  we 
recognized zero , $1.0 million and $1.0 million , respectively, in revenue under collaborative agreements pursuant to the terms of the Intrexon 
Collaboration. See Note 4, Collaborative Agreements , for a further discussion of the Intrexon Collaboration.

13.   Restructuring Expense 

In  November  2014,  we  completed  a  corporate  reorganization  to  focus  our  resources  on  advancing  our  PEGPH20  oncology  proprietary 
program and Enhanze collaborations. This reorganization resulted in a reduction in the workforce of approximately 13% , primarily in research 
and development.  

We  recorded  approximately  $1.2  million  of  severance  pay  and  benefits  expense  in  connection  with  the  reorganization,  of  which  $1.1 
million and $0.1 million was included in research and development expense and selling, general and administrative expense, respectively, in the 
consolidated  statement  of  operations  for  the  year  ended  December  31,  2014.  No  other  restructuring  charges  were  incurred.  We  made  cash 
payments of $0.7 million related to the restructuring expense for the year ended December 31, 2014. As of December 31, 2014, the restructuring 
liability was approximately $0.5 million and was included in current accrued expenses. The balance is expected to be paid in 2015.

manufacturing costs related to the product sales of bulk rHuPH20 for Herceptin SC and HyQvia in the amounts of $0.9 million , $6.5 
million  and  $2.6  million  ,  respectively.  Such  costs  were  incurred  prior  to  European  marketing  approvals  for  Herceptin  SC  and 
HyQvia, and therefore, they were charged to research and development expenses in the periods the costs were incurred.

About Halozyme

Halozyme Therapeutics is a biotechnology company focused on developing 

and commercializing novel oncology therapies that target the tumor 

microenvironment. Halozyme’s lead proprietary program, our investigational 

drug PEGPH20, applies a unique approach to targeting solid tumors, 

allowing increased access of co-administered cancer drug therapies to 

the tumor. PEGPH20 is currently in development for metastatic pancreatic 

cancer and non-small cell lung cancer and has potential across additional 

cancers in combination with different types of cancer therapies. In addition 

to its proprietary product portfolio, Halozyme has established value-driving 

partnerships with leading pharmaceutical companies including Roche, Pfizer, 

Janssen and Baxter for its drug delivery platform, ENHANZE™, which enables 

biologics and small molecule compounds that are currently administered 

intravenously to be delivered subcutaneously. Halozyme is headquartered in 

San Diego, CA. For more information on how we are innovating, please visit
