than 3,000 employees across the globe. In doing so, we built a foundation, 

with integrity and compliance at the center, that positions us to continue  

our momentum in 2019 and beyond. 

We know we still have work to do, as only a small fraction of the more than 

7,000 identified rare diseases have approved therapies. With 30 million

are waiting. The dedication of our employees enables us to stay focused on 

what matters most – delivering for patients. We are motivated and energized 

because we know lives are at stake. With a strong foundation in place,  

we will continue to push ourselves to redefine what it means to live with  

a rare disease.

employees for their passion and drive and to you, our shareholders, for  

supporting our mission.

Dan

L I V I N G   W I T H   P N H

Dan recalls experiencing symptoms of PNH as early as when he was a young teenager. He would bruise 
easily and fatigue was something he seemingly always lived with. After a period of rapid weight loss when he 
was 19, and at the insistence of a cousin who was a doctor, Dan consulted a hematologist. He was told based 
on his blood test results that he likely only had six months to a year to live. Dan remembers thinking he  
was young, invulnerable, invincible; how could he be that sick? Fortunately, Dan surpassed those odds,  
persevering despite years of countless blood tests, bone marrow biopsies, blood transfusions and  
misdiagnoses. Finally, at age 30, Dan was diagnosed with PNH and was able to receive treatment with  
SOLIRIS and get his disease under control.

Once I finally received a diagnosis and 
worked with my doctor, it was the  
first time that I felt my health and life  
could become stable.

I appreciate all of the little things like  
taking Justice to the store, or taking him  
to the park, or going to parades. Every  
day is a very big blessing for us.

When Justice was nine-months old, he woke one morning with facial swelling. His parents brought him to  

Urgent Care where he was treated for pink eye and sent home. Later that day, his body became very limp and 

his eyes could not focus. His parents rushed him to the local hospital, by which point Justice had begun to 

have a seizure. Doctors at the hospital were unable to stop his seizure and he was transferred to a specialist 

children’s hospital. Once there, the medical team discovered that Justice was experiencing kidney failure.  

He was intubated and started on dialysis, followed by plasmapheresis, while doctors tried to determine a  

diagnosis. Several days later, Justice was diagnosed with aHUS. His parents were devastated at first, but  

Justice’s doctor explained that his aHUS could be managed with SOLIRIS. Today, Justice is an energetic  

six-year old with a vibrant personality, bringing joy to everyone around him.

Our Mission

2018 was a year focused on strengthening our foundation, establishing a culture of 

high performance, with integrity and compliance at the center, and refocusing our 

strategy to drive Alexion into its next chapter. The foundation for 2019 is solid. We 

have a strong culture, clear business objectives, strong leadership, amazing teams 

and a promising pipeline. We have a clear purpose. People living with rare diseases 

are waiting. We are inspired and energized by our work together because we know 

there still is so much yet to do.

G rowing up, Jesse was very healthy, active and athletic with dreams of becoming 

an EMT and a firefighter. In his early 30s, he decided to start training to pursue 

these dreams more seriously. When he started feeling weaker at the gym and 

experienced double vision and a droopy eyelid, he knew something was wrong. His  

symptoms continued to worsen – his legs got weaker, he could no longer drive and wasn’t 

able to carry out many of his usual activities of daily living without his wife’s assistance. He 

met with a neurologist who diagnosed him with gMG. Unfortunately, Jesse subsequently 

experienced a myasthenic crisis so severe that he almost did not survive. He spent a month 

in the hospital rehabilitating and years being treated with a variety of medications to try  

and stabilize his gMG. When SOLIRIS was approved for gMG in 2017, Jesse’s neurologist  

recommended he begin treatment. Jesse remains on SOLIRIS today and feels as if he’s  

able to do more of the things he once thought he would have to give up forever.

ULTOMIRIS APPROVED, ESTABLISHING A NEW STANDARD OF CARE  

FOR PATIENTS WITH PNH 

In December 2018, ULTOMIRIS received U.S. FDA approval as the first and only long- 

acting C5 complement inhibitor administered every eight weeks for the treatment 

of adult patients with PNH.

U.S. Regulatory Submission Filing  

Alexion also announced plans to file a U.S. regulatory submission for ULTOMIRIS in 

aHUS in the first half of 2019, followed by the EU and Japan.

We are proud to bring ULTOMIRIS to patients suffering from PNH less than a year after 

reporting our positive Phase 3 data. Based on the totality of our compelling data from the 

largest Phase 3 program ever conducted in PNH, we believe ULTOMIRIS has the potential to 

become the new standard of care for patients with this devastating disease.

Every Day 
We Innovate

A central goal of our 2018 innovation strategy was rebuilding our pipeline. We  

completed four business development transactions, diversifying our portfolio into 

new therapeutic areas of focus. As we look back and compare our pipeline from 

2017 to our pipeline of today, the progress is clear, and we remain steadfast in our 

pursuit of groundbreaking innovation, as we aim to redefine what it means to  

live with a rare disease.

Trendy Brothers

L I V I N G   W I T H   L A L - D

When two-and-a-half-year-old Brendan was found to have elevated liver enzymes during routine  

preoperative bloodwork, his parents never imagined it was the first sign that all four of their sons were  

suffering from an ultra-rare devastating disease. Further test results on Brendan revealed he had Stage 1  

liver disease. Soon thereafter, his brother, Dakota, became ill. Doctors began hunting for a genetic disease 

that could potentially be affecting the whole family, but it took several years before all four boys were  

diagnosed with LAL-D. The four brothers began treatment with KANUMA and continue to receive it today.

Quinn was born a healthy, 11-pound baby boy. Shortly after birth, however, he began showing signs that 

something might be wrong. At his first wellness visit, his pediatrician noticed the circumference of his head 

was larger than normal and that his skull was asymmetrical. He didn’t stand up on his own until he was one-

and-a-half years old and did not take his first steps until he was two. He began losing baby teeth before they 

had even finished growing in and by his third birthday he had lost six of them. His parents knew something 

wasn’t right, and at the suggestion of a pediatric dentist, they had Quinn tested for metabolic disorders.  

After a blood test showed his alkaline phosphatase levels were extremely low, he was diagnosed with HPP. 

At age six, Quinn became the first U.S. patient approved for STRENSIQ and began treatment right away,  

making a meaningful difference in his life.

(dollars and shares in millions)

Overview

Alexion is a global biopharmaceutical company focused on serving patients and families affected by rare diseases 

through the innovation, development and commercialization of life-changing therapies.

We are the global leader in complement inhibition and have developed and commercialize the only two approved 
complement inhibitors to treat patients with paroxysmal nocturnal hemoglobinuria (PNH), as well as the first and only 
approved  complement  inhibitor  to  treat  atypical  hemolytic  uremic  syndrome  (aHUS)  and  anti-acetylcholine  receptor 
(AchR) antibody-positive generalized myasthenia gravis (gMG).  In addition, Alexion has two highly innovative enzyme 
replacement therapies for patients with life-threatening and ultra-rare metabolic disorders, hypophosphatasia (HPP) and 
lysosomal acid lipase deficiency (LAL-D).

As the leader in complement biology for over 20 years, Alexion focuses its research efforts on novel molecules 
and targets in the complement cascade, and its development efforts on the core therapeutic areas of hematology, 
nephrology, neurology, and metabolic disorders. We were incorporated in 1992 under the laws of the State of Delaware.

Products and Development Programs

We focus our products and development programs on life-transforming therapeutics for rare diseases for which 
we believe the current treatments are either non-existent or inadequate. We have developed or are developing innovative 
products for the following indications:

Paroxysmal Nocturnal
Hemoglobinuria (PNH)

PNH  is  a  debilitating  and  life-threatening,  ultra-rare  genetic  blood  disorder  defined  by  chronic 
uncontrolled complement activation leading to the destruction of red blood cells (hemolysis). Chronic 
hemolysis in patients with PNH may be associated with life-threatening thromboses, recurrent pain, 
kidney  disease,  disabling  fatigue,  impaired  quality  of  life,  severe  anemia,  pulmonary  hypertension, 
shortness of breath and intermittent episodes of dark-colored urine (hemoglobinuria).

Atypical Hemolytic
Uremic Syndrome
(aHUS)

aHUS is a severe and life-threatening, ultra-rare genetic disease characterized by chronic uncontrolled 
complement activation and thrombotic microangiopathy (TMA), the formation of blood clots in small 
blood vessels throughout the body, causing a reduction in platelet count (thrombocytopenia) and life-
threatening damage to the kidney, brain, heart and other vital organs.

Generalized Myasthenia
Gravis (gMG)

Myasthenia  Gravis  (MG)  is  a  debilitating,  complement-mediated  neuromuscular  disease  in  which 
patients suffer profound muscle weakness throughout the body, resulting in slurred speech, impaired 
swallowing and choking, double vision, upper and lower extremity weakness, disabling fatigue, shortness 
of breath due to respiratory muscle weakness and episodes of respiratory failure.

Hypophosphatasia
(HPP)

HPP is an ultra-rare genetic and progressive metabolic disease in which patients experience devastating 
effects on multiple systems of the body, leading to debilitating or life-threatening complications. HPP 
is characterized by defective bone mineralization that can lead to deformity of bones and other skeletal 
abnormalities, as well as systemic complications such as profound muscle weakness, seizures, pain, 
and respiratory failure leading to premature death in infants.

Lysosomal Acid Lipase
Deficiency (LAL
Deficiency or LAL-D)

LAL-D is a serious, life-threatening ultra-rare disease associated with premature mortality and significant 
morbidity. LAL-D is a chronic disease in which genetic mutations result in decreased activity of the LAL 
enzyme that leads to marked accumulation of lipids in vital organs, blood vessels, and other tissues, 
resulting in progressive and systemic organ damage including hepatic fibrosis, cirrhosis, liver failure, 
accelerated atherosclerosis, cardiovascular disease, and other devastating consequences. 

Relapsing Neuromyelitis
Optica Spectrum
Disorder (NMOSD)

Relapsing NMOSD is a severe and ultra-rare autoimmune disease of the central nervous system that 
primarily affects the optic nerves and the spinal cord. Each relapse of the disorder results in a stepwise 
accumulation of disability, including blindness and paralysis, and sometimes premature death.

Wilson Disease

Wilson disease is a rare disorder that can lead to severe liver disease, including cirrhosis and acute 
liver failure, as well as debilitating neurological morbidities such as impaired movement, gait, speech, 
swallowing, and psychiatric disorders.

6

 
Warm Autoimmune
Hemolytic Anemia
(WAIHA)

WAIHA is a rare autoimmune disorder caused by pathogenic Immunoglobulin G (IgG) antibodies that 
react with and cause the premature destruction of red blood cells at normal body temperature. The 
disease is often characterized by profound, and potentially life-threatening anemia and other acute 
complications, including severe and life-threatening hemolysis, severe weakness, enlarged spleen and/
or liver, rapid heart rate (tachycardia), chest pain, heart failure and fainting (syncope).

ULTOMIRIS (ALXN1210/ravulizumab-cwvz)

ULTOMIRIS is designed to inhibit a specific aspect 
of the complement component of the immune system 
and thereby treat inflammation associated with chronic 
disorders  in  several  therapeutic  areas,  including 
hematology, nephrology and neurology.  As of the date 
hereof, ULTOMIRIS has only been approved as a therapy 
in the US for adult patients with PNH.  ULTOMIRIS is a 
humanized monoclonal antibody that effectively blocks 
terminal  complement  activity  at  the  doses  currently 
prescribed. ULTOMIRIS is the first and only long-acting 
C5  inhibitor  that  provides  immediate  and  complete 
inhibition for eight weeks. 

In December 2018, ULTOMIRIS was approved by 
the U.S. Food and Drug Administration (FDA) as a new 
treatment option for adult patients living with PNH. 

In  June  2018,  we  submitted  a  Marketing 
Authorization  Application  (MAA)  to  the  European 
Medicines Agency (EMA) for approval of ULTOMIRIS for 
the treatment of patients with PNH and in July 2018 the 
MAA  was  accepted  for  review  in  the  European  Union 
(EU). In September 2018, we also filed an application 
Japan  Pharmaceuticals  and  Medical 
with 
Devices (PDMA)  for  the  approval  of  ULTOMIRIS  for 
patients with PNH.

the 

ULTOMIRIS has received Orphan Drug Designation 
(ODD) for the treatment of patients with PNH in the U.S., 
EU and Japan.

SOLIRIS (eculizumab)

SOLIRIS is designed to inhibit a specific aspect of 
the complement component of the immune system and 
thereby  treat  inflammation  associated  with  chronic 
disorders  in  several  therapeutic  areas,  including 
hematology,  nephrology  and  neurology.  SOLIRIS  is  a 
humanized monoclonal antibody that effectively blocks 
terminal  complement  activity  at  the  doses  currently 
prescribed. 

SOLIRIS is approved for the treatment of PNH in 
the U.S., Europe, Japan and in several other countries. 
We  are  sponsoring  a  multinational  registry  to  gather 
information regarding the natural history of patients with 
PNH  and  the  longer  term  outcomes  during  SOLIRIS 
treatment. In addition, SOLIRIS has been granted orphan 
drug designation for the treatment of PNH in the U.S., 
Europe, Japan and several other countries. 

SOLIRIS is approved for the treatment of pediatric 
and adult patients with aHUS in the U.S., Europe, Japan 
and  in  several  other  countries.  We  are  sponsoring  a 
multinational  registry  to  gather  information  regarding 
the natural history of patients with aHUS and the longer-
term outcomes during SOLIRIS treatment. In addition, 
the FDA and European Commission (EC) have granted 
SOLIRIS orphan drug designation for the treatment of 
patients with aHUS.

receptor 

In 2017, the FDA and EC approved SOLIRIS for the 
treatment  of  refractory  gMG  in  adults  who  are  anti-
acetylcholine 
(AChR)  antibody-positive. 
Additionally, in 2017 the Ministry of Health, Labour and 
Welfare  (MHLW)  in  Japan  approved  SOLIRIS  as  a 
treatment for patients with gMG who are AChR antibody-
positive  and  whose  symptoms  are  difficult  to  control 
with high-dose intravenous immunoglobulin therapy or 
plasmapheresis (PLEX).  SOLIRIS has received orphan 
drug designation for the treatment of patients with MG 
in the U.S. and Europe, and for the treatment of patients 
with refractory gMG, a subset of MG, in Japan.

 STRENSIQ (asfotase alfa)

STRENSIQ,  a 

targeted  enzyme 

replacement 
therapy,  is  the  first  and  only  approved  therapy  for 
patients with HPP and is designed to directly address 
underlying  causes  of  HPP  by  aiming  to  restore  the 
genetically  defective  metabolic  process, 
thereby 
preventing or reversing the severe and potentially life-
in  patients  with  HPP. 
threatening  complications 
STRENSIQ  is  approved  in  the  U.S.  for  patients  with 

perinatal-, infantile- and juvenile-onset HPP, Europe for 
the treatment of patients with pediatric-onset HPP, and 
Japan  for  the  treatment  of  patients  with  HPP.  We  are 
sponsoring a multinational registry to gather information 
regarding the natural history of patients with HPP and 
the longer-term outcomes during STRENSIQ treatment.

KANUMA (sebelipase alfa)

KANUMA, a recombinant form of the human LAL 
enzyme, is the only enzyme-replacement therapy that is 
approved  for  the  treatment  for  patients  with  LAL-D. 
KANUMA is approved in the U.S. for the treatment of 
patients  with  LAL-D,  Europe  for  long-term  enzyme 
replacement therapy in patients with LAL-D, and Japan 
for  the  treatment  of  patients  with  LAL-D.  We  are 
sponsoring a multinational registry to gather information 
regarding the natural history of patients with LAL-D and 
the longer-term outcomes during KANUMA treatment.

ULTOMIRIS (ALXN1210/ravulizumab-cwvz)

ALXN1210  (ravulizumab-cwvz)  is  an  innovative, 
long-acting  C5  inhibitor  discovered  and  developed  by 
Alexion  that  works  by  inhibiting  the  C5  protein  in  the 
terminal  complement  cascade.  In  clinical  studies, 
rapid,  complete,  and 
ALXN1210  demonstrated 
sustained reduction of free C5 levels for eight weeks. 

Intravenous (IV)

Enrollment was completed in late May 2018 in a 
Phase III, single arm, multicenter study to evaluate the 
safety  and  efficacy  of  ALXN1210  administered  by  IV 
infusion every 8 weeks to adult patients with aHUS who 
have never been treated with a complement inhibitor.   
In January 2019, we announced the results of the Phase 

III study with ALXN1210 meeting its primary objective 
in complement inhibitor-naïve patients with aHUS. In the 
initial  26  week  treatment  period  in  this  study,  53.6 
percent of patients demonstrated complete thrombotic 
microangiopathy (TMA) response.  A second Phase III, 
single  arm,  multicenter  study  to  evaluate  the  safety, 
(PK),  and  pharmaco-
efficacy,  pharmacokinetics 
dynamics (PD) of ALXN1210 administered by IV infusion 
every  8  weeks 
(including 
adolescents) with aHUS who have never been treated 
with a complement inhibitor (inhibitor-naïve patients) is 
ongoing. 

in  pediatric  patients 

Alexion  plans  to  initiate  a  Phase  III  study  with 
ALXN1210 administered by IV infusion every 8 weeks 
to adult patients for the treatment of gMG in 2019.

8

In  addition  to  aHUS  and  gMG,  Alexion  plans  to 
initiate  clinical  studies  of  ALXN1210  in  NMOSD.    In 
addition, in 2019 we also plan to initiate proof of concept 
trials for ALXN1210 as a therapy for  Amyotrophic Lateral 
Sclerosis  (ALS),  and  Primary  Progressive  Multiple 
Sclerosis (PPMS).

Subcutaneous (SC) Delivery

In late 2018, Alexion initiated a single, PK-based 
Phase III study of ALXN1210 delivered subcutaneously 
once  per  week  to  PNH  patients  to  support  regulatory 
approval submissions in both PNH and aHUS.

In  October  2017,  the  FDA  granted  orphan  drug 
formulation  of 

designation  to  the  subcutaneous 
ALXN1210 for the treatment of aHUS.

ALXN1810 Subcutaneous (SC) Delivery 

ALXN1810 combines ALXN1210 with recombinant 
human hyaluronidase enzyme (rHuPH20) from Halozyme 
Therapeutics,  Inc.  to  potentially  further  extend  the  
dosing  interval  for  ALXN1210  SC  to  once  every  two 
weeks or once per month. A SC healthy volunteer study 
with ALXN1810 was initiated in August 2018.

SOLIRIS (eculizumab)

In September 2018, we announced the results of 
the Phase III global, randomized, double-blind, placebo-
controlled study to evaluate eculizumab as a treatment 
for patients with relapsing NMOSD. The study met its 
primary  endpoint  of  time  to  first  adjudicated  on-trial 
relapse, demonstrating that treatment with eculizumab 
reduced  the  risk  of  NMOSD  relapse  by  94.2  percent 
compared  to  placebo.  At  48  weeks,  97.9  percent  of 
patients  receiving  eculizumab  were  free  of  relapse 
compared to 63.2 percent of patients receiving placebo. 
Eculizumab  had  a  safety  profile  consistent  with  that 
seen in previous clinical studies. The FDA, EC, and MHLW 
have each granted orphan designation for eculizumab 
as a treatment for patients with relapsing NMOSD.

In December 2018, we submitted our requests for 
regulatory approval to the FDA and our MAA in the EU 
for eculizumab for the potential treatment of NMOSD.

ALXN1840 (WTX101)

ALXN1840 

(WTX101),  an 

innovative  product 
candidate  that  addresses  the  underlying  cause  of 
Wilson  disease,  is  a  first-in-class  oral  copper-binding 
agent with a unique mechanism of action and ability to 
access  and  bind  copper  from  serum  and  promote  its 
removal from the liver. 

ALXN1840  is  in  Phase  III  development  as  a 
treatment  for  Wilson  disease.  In  addition,  ALXN1840 
has  received  Fast  Track  designation  in  the  U.S.  and 
Orphan  Drug  Designation  for  the  treatment  of  Wilson 
disease in the U.S. and EU.

ALXN1830 (SYNT001)

ALXN1830 (SYNT001) is a humanized monoclonal 
antibody that is designed to inhibit the interaction of the 
neonatal Fc receptor (FcRn) with IgG and IgG immune 
complexes and has the potential to improve treatment 
in a number of rare IgG-mediated diseases. ALXN1830 
(SYNT001) is currently being evaluated in Phase 1b/2a 
studies  in  patients  with  warm  autoimmune  hemolytic 
anemia (WAIHA) and in patients with pemphigus vulgaris 
(PV) or pemphigus foliaceus (PF). In 2019, Alexion plans 
to initiate two pivotal trials, one in WAIHA and one in 
gMG.

Manufacturing

We utilize both internal manufacturing facilities and 
third party contract manufacturers to supply clinical and 
commercial  quantities  of  our  products  and  product 
candidates.  Our  internal  manufacturing  capability 
includes  our  Ireland  facilities,  a  fill/finish  facility  in 
Athlone  and  a  packaging  facility  in  Dublin,  as  well  as 
facilities  in  Massachusetts  and  Georgia.  Third  party 
contract manufacturers, including Lonza Group AG and 
its affiliates (Lonza), provide bulk drug substance as well 
as  other  manufacturing  services  like  purification, 
product filling, finishing, packaging, and labeling. 

total 

We have various agreements with Lonza through 
2029,  with 
remaining 
non-cancellable 
If  we 
commitments  of  approximately  $1,084.6. 
terminate certain supply agreements with Lonza without 
cause, we will be required to pay for product scheduled 
for  manufacture  under  our  arrangements.  Under  an 
existing arrangement, we pay Lonza a royalty on sales 
of  SOLIRIS  that  was  previously  manufactured  at  the 
Alexion Rhode Island Manufacturing Facility (ARIMF) and 
a  payment  with 
to  sales  of  SOLIRIS 
manufactured at Lonza facilities. The ARIMF site was 
sold in 2018. Lonza is in the process of qualifying a new 
manufacturing facility dedicated to Alexion products and 
commitments entered into under this arrangement are 
included in the non-cancellable commitments amount 
noted above.

respect 

In addition, we have non-cancellable commitments 
of approximately $104.1 through 2020 with other third 
party manufacturers.

In April 2014, we purchased a fill/finish facility in 
Athlone, Ireland, which has been refurbished to become 
our first company-owned fill/finish facility. In July 2016, 
we  announced  plans  to  construct  a  new  biologics 
manufacturing  facility  at  this  site,  the  construction  of 
this 
is  on-going  and,  based  on  current 
expectations,  we  anticipate  this  facility  will  receive 
regulatory approval in 2020.

In May 2015, we announced plans to construct a 
new  biologics  manufacturing  facility  on  our  existing 
property  in  Dublin,  Ireland,  the  construction  of  this 
facility  has  commenced  and,  based  on  current

expectations,  we  anticipate  this  facility  will  receive 
regulatory approval in 2020.

Sales and Marketing

We have established a commercial organization to 
support current and future sales of our products in the 
U.S.,  Europe,  Japan,  Latin  America,  Asia  Pacific 
countries, and other territories. Our sales force is small 
compared to those for other pharmaceutical companies 
with  similar  revenues;  however,  we  believe  that  a 
relatively smaller sales force is appropriate to effectively 
market our products due to the incidence and prevalence 
of  rare  diseases.  If  we  receive  regulatory  approval  in 
new  territories  or  for  new  products  or  indications,  we 
may expand our own commercial organizations in such 
territories and market and sell our products through our 
own  sales  force  in  these  territories.  However,  we 
evaluate each jurisdiction on a country-by-country basis, 
and, in certain territories, we promote our products in 
collaboration  with  marketing  partners  or  rely  on 
relationships  with  one  or  more  companies  with 
established distribution systems and direct sales forces 
in  certain  countries.    In  addition,  we  have  recently 
announced that, in an effort to align the structure of our 
commercial organization with our re-focused corporate 
strategy and to realize operational efficiencies, certain 
portions of our international commercial operations will 
transition to a new operating model in which sales and 
marketing efforts in the designated countries will rely to 
a greater extent on third-party entities and alliances to 
promote  and  sell  our  products,  and  our  direct  sales 
presence will decrease in these regions (as we focus 
our direct sales resources on those regions where it can 
have a more cost-effective impact). 

Customers

Our  customers  are  primarily  comprised  of 
distributors,  pharmacies,  hospitals,  hospital  buying 
groups, and other healthcare providers. In some cases, 
we  may  also  sell  our  products  to  governments  and 
government agencies. 

For  the  year  ended  December 31,  2018,  four 
customers accounted for 50.3% of our product sales, 
with these individual customers ranging from 10.0% to 
16.4%  of  product  sales.  For 
the  year  ended 
December 31,  2017,  three  customers  accounted  for 
37.0%  of  our  product  sales,  with  these  individual 
customers  ranging  from  10.8%  to  15.0%  of  product 
sales. For the year ended December 31,  2016,  three 
customers accounted for 36.7% of our product sales, 
with these individual customers ranging from 10.0% to 
16.0% of product sales. 

Because  of  factors  such  as  the  pricing  of  our 
products,  the  limited  number  of  patients,  the  short 
period from product sale to patient use and the lack of 
contractual return rights, customers often carry limited 
inventory.  We  monitor  inventory  within  our  sales 

channels 
to  determine  whether  deferrals  are 
appropriate based on factors such as inventory levels 
compared  to  demand,  contractual  terms,  financial 
strength  of  distributors  and  our  ability  to  estimate 
returns.

Analysis – Net Product Sales,” and Note 19 “Segment 
Information” of the Consolidated Financial Statements

information by geographic areas.

Intellectual Property Rights and Market Exclusivity

Patents  and  other  intellectual  property  rights 
protect our investment in discovering, developing and 
marketing our products, and are therefore important to 
our business. We own or license rights to many patents 
in the U.S. and foreign countries that cover our products 
and  investigational  compounds.  We  also  file  and 
prosecute  many  patent  applications  covering  new 
technologies and inventions that we believe are or may 
become  meaningful  to  our  business.  In  addition  to 
patents, we rely on trade secrets, know-how, trademarks, 
other  forms  of  intellectual  property  and  regulatory 
exclusivity. Our intellectual property rights have material 
value and we act to protect them.

Patent rights and regulatory protections are the two 
principal  considerations  that  determine  the  period  of 
market exclusivity for our products. It is during the period 
of  market  exclusivity  that  our  products  have  their 
greatest commercial value.

Patents  provide  a  right  to  exclude  others  from 
practicing an invention for a defined period of time. In 
our business, patents may cover the active ingredients, 
uses,  formulations,  doses,  administrations,  delivery 
mechanisms,  manufacturing  processes  and  other 
aspects of a product. The period of patent protection 
for any given product may depend on the expiration date 
of various patents and may differ from country to country 
according to the type of patents, the scope of coverage 
and the remedies for infringement available in a country. 
Because  a  significant  portion  of  a  biopharmaceutical 
product’s patent protection can elapse during the course 
of developing and obtaining regulatory approval of the 
product,  certain  countries  provide  compensatory 
mechanisms 
the 
biopharmaceutical products.

to  extend  patent 

terms 

for 

Regulatory  protections  are  another  source  of 
exclusive rights that contribute toward market exclusivity 
for our products. Many developed countries provide such 
non-patent  incentives  to  develop  medicines.  For 
example, countries provide data protection for a period 
of time after the approval of a new drug, during which 
regulatory agencies may not rely on the innovator’s data 
to approve a biosimilar or generic copy. Some countries 
provide additional incentives to develop medicines for 
rare  diseases,  or  orphan  drugs,  and  medicines  for 
pediatric patients. Regulatory protections can work in 

10

conjunction  with  patents 
to  strengthen  market 
exclusivity, and in countries where patent protection has 
expired  or  does  not  exist,  regulatory  protections  can 
extend a product’s market exclusivity period. Different 
forms  of  regulatory  protection  are  described  in  the 
section  of  this  Annual  Report  on  Form  10-K  titled 
Government  Regulation.  For  information  regarding 
lawsuits alleging that ULTOMIRIS infringes patents held 
by  a  third  party,  see  Note  11  “Commitments  and 
Contingencies” to the notes to the consolidated financial 
statements included elsewhere in this Annual Report on 
Form 10-K.

SOLIRIS Exclusivity

With respect to SOLIRIS, we own an issued U.S. 
patent that covers the eculizumab composition of matter 
that will expire in 2021, taking into account patent term 
extension. We also own other issued U.S. patents that 
cover  the  composition,  use  and 
formulation  of 
eculizumab,  that  expire  in  2027.  SOLIRIS  is  also 
protected in the U.S. by regulatory data exclusivity that 
will expire in March 2019.  SOLIRIS also benefits from 
orphan  drug  exclusivity  for  treating  gMG  until  2024 
(orphan drug exclusivity for SOLIRIS for treating PNH and 
aHUS  previously  expired). 
In  Europe  we  have 
supplementary protection certificates that extend rights 
associated  with  a  composition  of  matter  patent  until 
2020 in certain countries. SOLIRIS is also protected in 
Europe by orphan drug exclusivity until 2019 for PNH, 
through late 2023 for aHUS and until 2027 for gMG. In 
Japan we own issued patents that cover the eculizumab 
composition of matter and will expire in 2019 and 2027. 
SOLIRIS  is  also  protected  in  Japan  by  orphan  drug 
exclusivity until 2020 for PNH, until 2023 for aHUS and 
until 2027 for gMG. In addition to the foregoing patent 
and regulatory protections, we own other patents and 
pending patent applications that are directed to various 
aspects of eculizumab and which may provide additional 
protection for SOLIRIS in the U.S., Europe, Japan and 
other countries. 

ULTOMIRIS Exclusivity

that 

indication 

With respect to ULTOMIRIS, we own issued U.S. 
patents that cover the composition, use and formulation 
of ravulizumab which will expire in 2035. ULTOMIRIS is 
also protected in the U.S. by regulatory data exclusivity 
until  2030  and  we  have  applied  for  orphan  drug 
exclusivity  for  treating  PNH,  which,  if  granted,  would 
through  2025.  Although 
protect 
ULTOMIRIS  is  not  yet  approved  for  any  indication  in 
Europe or Japan, it is also protected in those regions by 
patents that cover ravulizumab which will expire in 2035. 
If ULTOMIRIS is approved in Europe or Japan, we also 
expect regulatory protections to apply in those regions. 
In  addition  to  the  foregoing  patent  and  regulatory 
protections, we own other patents and pending patent 
applications  that  are  directed  to  various  aspects  of 
ravulizumab and which may provide additional protection 

for  ULTOMIRIS  in  the  U.S.,  Europe,  Japan  and  other 
countries.

STRENSIQ Exclusivity

With respect to STRENSIQ, we own an issued U.S. 
patent  that  covers  the  asfotase  alfa  composition  of 
matter that will expire in 2026. We have applied for an 
extension of this U.S. patent term. STRENSIQ is also 
protected  in  the  U.S.  by  orphan  drug  exclusivity  until 
2022 and by regulatory data exclusivity until 2027. In 
Europe,  we  own  two  issued  patents  that  cover  the 
asfotase alfa composition of matter and will expire in 
2025  and  2028.  We  have  applied  for  supplementary 
protection  certificates  in  the  European  countries. 
STRENSIQ is also protected in Europe by orphan drug 
exclusivity and regulatory data exclusivity until 2025. In 
other countries we own corresponding patents that will 
expire between 2025 and 2028, not including possible 
extensions. 

KANUMA Exclusivity

With respect to KANUMA, we own issued patents 
in  the  U.S.,  Europe  and  other  countries  that  cover 
methods  of  using  the  product  to  treat  LAL-D  and  will 
expire in 2031. We maintained the European patent in 
an opposition proceeding that was favorably resolved in 
2017.  An  exclusively  licensed  composition  of  matter 
patent  also  protects  KANUMA  in  certain  European 
countries until it expires in 2021, though we also applied 
for  supplementary  protection  certificates  in  those 
countries.  In  the  U.S.,  KANUMA  also  is  protected  by 
orphan drug exclusivity until 2022 and by regulatory data 
exclusivity until 2027. In Europe it is protected by orphan 
drug  exclusivity  and  regulatory  data  exclusivity  until 
2025.

Investigational Compounds

We also own U.S. and foreign patents and patent 
applications that protect our investigational compounds 
and product candidates. At present, we do not  know 
whether any such investigational compound or product 
candidate will be approved for human use and sale.

License and Collaboration Agreements

From time to time, we enter into arrangements with 
third  parties,  including  collaboration  and  licensing 
arrangements, for the development, manufacture and 
commercialization of products and product candidates. 
These strategic alliances are intended to strengthen and 
advance our R&D capabilities and diversify our product 
pipeline to support the growth of our marketed product 
base.  The  arrangements,  which  generally  provide 
Alexion  with  rights  to  specialized  technology  and 
intellectual  property  for  the  development  of  potential 
product  candidates,  often  require  non-refundable, 
upfront  license  fees,  development,  regulatory  and 
commercial milestones, as well as royalty payments on 
commercial sales.

Importance of Intellectual Property Exclusivities and 
Rights

The pharmaceutical industry places considerable 
importance on obtaining and enforcing patent (including 
licensed  patents),  trade  secret  and  other  intellectual 
property  protection  for  new  therapies,  technologies, 
products,  services  and  processes.  Our  success 
therefore depends, in part, on our ability to obtain and 
enforce  our  patents  (including  licensed  patents)  and 
other intellectual property rights necessary to protect 
our current and future products, to obtain and preserve 
our  trade  secrets  and  other  confidential  intellectual 
property and to avoid or neutralize intellectual property 
threats from third parties. The existence of patents does 
not  guarantee  our  right  to  practice  the  patented 
technology  or  commercialize  the  patented  product. 
Litigation,  oppositions,  inter  partes  reviews  or  other 
proceedings are, have been and may in the future be 
necessary in some instances to determine the validity 
and  scope  of  certain  of  our  patents,  regulatory 
exclusivities  or  other  proprietary  rights,  and  in  other 
instances  to  determine  the  validity,  scope  or  non-
infringement  of  certain  patent  rights  claimed  by  third 
parties to be pertinent to the manufacture, use or sale 
of  our  products. We  may  also  face  challenges  to  our 
patents,  regulatory  exclusivities  and  other  proprietary 
rights  covering  our  products  by  manufacturers  of 
biosimilars.  For  additional  information,  see  Item 1A 
“Risk Factors - Risks Related to Intellectual Property” 
elsewhere in this Annual Report on Form 10-K (including 
a  recent  European  Patent  Office  ruling  to  revoke  a 
previously issued patent relating to the formulation of 
SOLIRIS).

Government Regulation 

Drug Development and Approval in the United States 

labeling,  storage, 

The  preclinical  studies  and  clinical  testing, 
manufacture, 
record  keeping, 
advertising,  promotion,  pharmacovigilance  reporting, 
export,  and  marketing,  among  other  things,  of  our 
products and product candidates, including ULTOMIRIS, 
SOLIRIS,  STRENSIQ  and  KANUMA,  are  subject  to 
extensive regulation by governmental authorities in the 
U.S., the EU, Japan and other territories. In the U.S., 
pharmaceutical products are regulated by the FDA under 
the Federal Food, Drug, and Cosmetic Act and other laws, 
including,  in  the  case  of  biologics,  the  Public  Health 
Service Act. Our four approved products are regulated 
by  the  FDA  as  biologics.  Biologics  require  the 
submission of a Biologics License Application (BLA) and 
approval by the FDA prior to being marketed in the U.S. 
In the case of KANUMA, which is derived from egg whites 
from select hens, we also submitted a New Animal Drug 
Application 
the  FDA. 
Manufacturers  of  biologics  and  drugs  derived  from 
animal origin may also be subject to state regulation. 
Failure to comply with FDA and state requirements, both 
before and after product approval, may subject us and/

for  approval  by 

(NADA) 

or our partners, contract manufacturers, and suppliers 
to  administrative  or  judicial  sanctions,  including  FDA 
refusal to approve applications, warning letters, product 
recalls, product seizures, total or partial suspension of 
production  or  distribution, 
fines  and/or  criminal 
prosecution.

The process for obtaining regulatory approval to 
market a biologic is expensive, often takes many years, 
and can vary substantially based on the type, complexity, 
and  novelty  of  the  product  candidates  involved.  The 
steps required before a biologic may be approved for 
marketing of an indication in the U.S. generally include:

(1) preclinical laboratory tests and animal tests;

(2) submission to the FDA of an investigational 
new drug (IND) application for human clinical 
testing, which must become effective before 
human clinical trials may commence;

(3) adequate and well-controlled human clinical 
trials to establish the safety and efficacy of 
the product for its intended use;

(4)  submission  to  the  FDA  of  a  BLA  or 

supplemental BLA;

(5)  FDA  pre-approval 

the 
manufacturing sites identified in the BLA; and

inspection  of 

(6)  FDA  review  and  approval  of  the  BLA  or 

supplemental BLA.

tests 

intended 

Preclinical studies include laboratory evaluation of 
product  chemistry  and 
formulation,  as  well  as 
toxicological  and  pharmacological  animal  studies  to 
assess the potential safety and efficacy of the product 
candidate.  Preclinical  safety 
for 
submission to FDA must be conducted in compliance 
with FDA’s Good Laboratory Practice (GLP) regulations 
and the U.S. Department of Agriculture’s Animal Welfare 
Act. The results of the preclinical tests, together with 
manufacturing  information  and  analytical  data,  are 
submitted to the FDA as part of an IND application which 
must become effective before human clinical trials may 
be  commenced.  The  IND  will  automatically  become 
effective 30 days after receipt by the FDA, unless the 
FDA, before that time, raises concerns about the drug 
candidate or the conduct of the trials as outlined in the 
IND.  The  IND  sponsor  and  the  FDA  must  resolve  any 
outstanding concerns before clinical trials can proceed. 
We cannot assure you that submission of an IND will 
result in FDA authorization to commence clinical trials 
or that once commenced, other concerns will not arise 
that will prevent the trials from moving forward. FDA may 
stop the clinical trials by placing them on “clinical hold” 
because  of  concerns  about  the  safety  of  the  product 
being tested, or for other reasons.

Clinical  trials  involve  the  administration  of  the 
investigational  product  to  healthy  volunteers  or  to 
patients,  under  the  supervision  of  qualified  principal 
investigators. The conduct of clinical trials is subject to 

12

extensive  regulation,  including  compliance  with  the 
FDA’s  bioresearch  monitoring  regulations  and  Good 
Clinical  Practice  (GCP)  requirements,  which  establish 
standards  for  conducting,  recording  data  from,  and 
reporting the results of clinical trials, and are intended 
to assure that the data and reported results are credible 
and accurate, and that the rights, safety, and well-being 
of study participants are protected. Clinical trials must 
be conducted in accordance with protocols that detail 
the objectives of the study, the criteria for determining 
subject  eligibility,  the  dosing  plan,  patient  monitoring 
requirements, timely reporting of adverse events, and 
other elements necessary to ensure patient safety, and 
any efficacy criteria to be evaluated. Each protocol must 
be submitted to FDA as part of the IND; further, each 
clinical study at each clinical site must be reviewed and 
approved by an independent institutional review board, 
prior  to  the  recruitment  of  subjects.  The  institutional 
review board’s role is to protect the rights and welfare 
of  human  subjects  involved  in  clinical  studies  by 
evaluating, among other things, the potential risks and 
benefits to subjects, processes for obtaining informed 
consent,  monitoring  of  data  to  ensure  subject  safety, 
and provisions to protect the subjects’ privacy. Foreign 
studies conducted under an IND application must meet 
the  same  requirements  that  apply  to  studies  being 
conducted  in  the  U.S.  Data  from  a  foreign  study  not 
conducted under an IND may be submitted in support 
of a BLA if the study was conducted in accordance with 
GCP and FDA is able to validate the data.

Clinical  trials  are  typically  conducted  in  three 
sequential  phases,  but  the  phases  may  overlap  and 
different  trials  may  be  initiated  with  the  same  drug 
candidate  within  the  same  phase  of  development  in 
similar or differing patient populations. Phase I studies 
may be conducted in a limited number of patients, but 
are usually conducted in healthy volunteer subjects. The 
drug is usually tested for safety and, as appropriate, for 
absorption,  metabolism, 
excretion, 
pharmaco-dynamics  and  pharmaco-kinetics.  Phase  II 
usually  involves  studies  in  a  larger,  but  still  limited 
patient population to evaluate preliminarily the efficacy 
of the drug candidate for specific, targeted indications; 
to determine dosage tolerance and optimal dosage; and 
to  identify  possible  short-term  adverse  effects  and 
safety risks.

distribution, 

Phase III trials are undertaken to gather additional 
information to evaluate the product’s overall risk-benefit 
profile,  and  to  provide  a  basis  for  physician  labeling. 
Phase  III  trials  evaluate  clinical  efficacy  of  a  specific 
endpoint and test further for safety within an expanded 
patient population at geographically dispersed clinical 
study sites. Phase I, Phase II or Phase III testing might 
not be completed successfully within any specific time 
period,  if  at  all,  with  respect  to  any  of  our  product 
candidates. Results from one trial are not necessarily 
predictive of results from later trials. Furthermore, the 
FDA, sponsor or institutional review board may suspend 

clinical trials at any time on various grounds, including 
a finding that the subjects or patients are being exposed 
to an unacceptable health risk.

(NIH) 

Institutes  of  Health 

We  must  register  each  controlled  clinical  trial, 
other than Phase I trials, on a website administered by 
National 
(http://
clinicaltrials.gov). Registration must occur not later than 
21  days  after  the  first  patient  is  enrolled,  and  the 
submission must include descriptive information (e.g., 
a summary in lay terms of the study design, type and 
desired outcome), recruitment information (e.g., target 
number of participants and whether healthy volunteers 
are  accepted),  location  and  contact  information,  and 
other  administrative  data  (e.g.,  FDA  identification 
numbers).  Within  one  year  of  a  trial’s  completion, 
information about the trial including characteristics of 
the patient sample, primary and secondary outcomes, 
trial results written in lay and technical terms, and the 
full  trial  protocol  must  be  submitted  to  the  NIH.  The 
results information is posted to the website unless the 
drug has not yet been approved, in which case the NIH 
posts the information shortly after approval. A BLA, BLA 
supplement, and certain other submissions to the FDA 
require  certification  of  compliance  with  these  clinical 
trials database requirements.

fees 

The results of the preclinical studies and clinical 
trials, together with other detailed information, including 
information on the manufacture and composition of the 
product  and  proposed  labeling  for  the  product,  are 
submitted  to  the  FDA  as  part  of  a  BLA  requesting 
approval to market the product candidate for a proposed 
indication. Under the Prescription Drug User Fee Act, as 
amended, the fees payable to the FDA for reviewing a 
for  commercial 
BLA,  as  well  as  annual 
manufacturing  establishments  and 
for  approved 
products, can be substantial. The BLA review fee alone 
can  exceed  $2.0  subject  to  certain  limited  deferrals, 
waivers and reductions that may be available. Each BLA 
submitted to the FDA for approval is typically reviewed 
for administrative completeness and reviewability within 
sixty days following submission of the application. If the 
FDA  finds  the  BLA  sufficiently  complete,  the  FDA  will 
“file”  the  BLA,  thus  triggering  a  full  review  of  the 
application. The FDA may refuse to file any BLA that it 
deems incomplete or not properly reviewable at the time 
of submission. FDA performance goals provide for action 
on an application within 12 months of submission. The 
FDA,  however,  may  not  approve  a  drug  within  these 
established goals and its review goals  are subject to 
change from time to time because the review process 
is  often  significantly  extended  by  FDA  requests  for 
additional  information  or  clarification.  As  part  of  its 
review,  the  FDA  may  refer  the  BLA  to  an  advisory 
committee composed of outside experts for evaluation 
and a recommendation as to whether the application 
should be approved. Although the FDA is not bound by 
the  recommendation  of  an  advisory  committee,  the 
agency usually has followed such recommendations.

Further, the outcome of the review, even if generally 
favorable, may not be an actual approval but instead a 
“complete  response  letter”  communicating  the  FDA’s 
decision  not  to  approve  the  application,  outlining  the 
deficiencies in the BLA, and identifying what information 
and/or data (including additional pre-clinical or clinical 
data) is required before the application can be approved. 
Even  if  such  additional  information  and  data  are 
submitted, the FDA may decide that the BLA still does 
not meet the standards for approval. Data from clinical 
trials  are  not  always  conclusive  and  the  FDA  may 
interpret data differently than we do.

manufactured and will not approve the product unless 
the  facilities  comply  with  the  FDA’s  current  Good 
Manufacturer  Practice  (cGMP)  requirements.  The  FDA 
may deny approval of a BLA if applicable statutory or 
regulatory  criteria  are  not  satisfied,  or  may  require 
additional testing or information, which  can  delay the 
approval process. FDA approval of any BLA may include 
many delays and requests for additional information or 
never be granted. If a product is approved, the approval 
will impose limitations on the indicated uses for which 
the product may be marketed, may require that warning 
statements be included in the product labeling, and may 
require that additional studies be conducted following 
approval as a condition of the approval. FDA also may 
impose 
restrictions  and  conditions  on  product 
distribution, prescribing or dispensing in the form of a 
Risk  Evaluation  and  Mitigation  Strategy  (REMS),  or 
otherwise limit the scope of any approval. A REMS may 
include  various  elements,  ranging  from  a  medication 
guide to limitations on who may prescribe or dispense 
the  drug,  depending  on  what  the  FDA  considers 
necessary  for  the  safe  use  of  the  drug.  To  market  a 
product  for  other  indicated  uses,  or  to  make  certain 
manufacturing  or  other  changes,  requires  FDA  review 
and approval of a BLA supplement or new BLA and the 
payment  of  applicable  review  fees.  Further  post-
marketing testing and surveillance to monitor the safety 
or efficacy of a product may be required. In addition, new 
government requirements may be established that could 
delay  or  prevent  regulatory  approval  of  our  product 
candidates under development.

In  2010,  the  Biologics  Price  Competition  and 
Innovation Act (BPCIA) was enacted, creating a statutory 
pathway for licensure, or approval, of biological products 
that are biosimilar to, and possibly interchangeable with, 
reference biological products licensed under the Public 
Health  Service  Act.  The  objectives  of  the  BPCIA  are 
conceptually  similar  to  those  of  the  Drug  Price 
Competition and Patent Term Restoration Act of 1984, 
commonly referred to as the “Hatch-Waxman Act”, which 
established  abbreviated  pathways  for  the  approval  of 
small  molecule  drug  products.  Under  the  BPCIA, 
innovator manufacturers of original reference biological 
products are granted 12 years of exclusive use before 

14

biosimilar versions of such products can be licensed for 
marketing in the U.S. This means that the FDA may not 
approve  an  application  for  a  biosimilar  version  of  a 
reference biological product until 12 years after the date 
of approval of the reference biological product (with a 
potential  six-month  extension  of  exclusivity  if  certain 
pediatric studies are conducted and the results reported 
to  FDA),  although  a  biosimilar  application  may  be 
submitted four years after the date of licensure of the 
reference  biological  product.  Additionally,  the  BPCIA 
establishes  procedures  by  which 
the  biosimilar 
applicant must provide information about its application 
and product to the reference product sponsor, and by 
which information about potentially relevant patents is 
shared  and  litigation  over  patents  may  proceed  in 
advance of approval. The BPCIA also provides a period 
of exclusivity for the first biosimilar to be determined by 
the  FDA  to  be  interchangeable  with  the  reference 
product.

FDA has released numerous guidance documents 
interpreting the BPCIA in recent years. These guidance 
documents,  among  other  things,  elaborate  on  the 
definition of a biosimilar as a biological product that is 
highly similar to an already approved biological product, 
notwithstanding minor differences in clinically inactive 
components,  and  for  which  there  are  no  clinically 
meaningful differences between the biosimilar and the 
approved biological product in terms of the safety, purity, 
and potency. The FDA has also released final guidance 
documents on the assignment of clearly distinguishable 
nonproprietary  product  names  for  both  biologic  and 
biosimilar products, labeling for biosimilar products, and 
questions and answers on issues involving biosimilar 
development,  as  well  as  draft  guidance  on 
interchangeability and evaluation of analytical similarity.

The  FDA  approved  the  first  biosimilar  product 
under the BPCIA in 2015, and as of December 2018, 
sixteen (16) biosimilar products have been approved in 
total. The agency continues to refine the procedures and 
standards  it  will  apply  in  implementing  this  approval 
pathway.  In  July  2018,  the  FDA  issued  a  Biosimilars 
Action Plan, asserting its intent to take steps to facilitate 
biosimilars competition. We anticipate that the contours 
of the BPCIA will continue to be defined as the statute 
is implemented over a period of years. This likely will be 
accomplished  by  a  variety  of  means,  including  FDA 
issuance of guidance documents, proposed regulations, 
and  decisions  in  the  course  of  considering  specific 
applications.  The  approval  of  a  biologic  product 
biosimilar  to  one  of  our  products,  including  SOLIRIS,  
could have a material impact on our business because 
it may be significantly less costly to bring to market and 
may be priced significantly lower than our products.

Both before and after the FDA approves a product, 
the manufacturer and the holder or holders of the BLA, 
and in the case of KANUMA, the NADA, for the product 
are  subject  to  comprehensive  regulatory  oversight.  If 
ongoing regulatory requirements are not satisfied or if 

safety  problems  occur  after  the  product  reaches  the 
market, the FDA may at any time withdraw its approval 
or  take  actions  that  would  suspend  marketing.  For 
example, quality control and manufacturing procedures 
must  conform,  on  an  ongoing  basis,  to  cGMP 
requirements,  and  the  FDA  periodically  subjects 
manufacturing facilities to unannounced inspections to 
assess  compliance  with  cGMP.  Failure  to  comply  with 
applicable cGMP requirements and other conditions of 
product approval may lead the FDA to take regulatory 
action, 
recalls,  civil  penalties, 
injunctions,  suspension  of  manufacturing  operations, 
operating  restrictions,  withdrawal  of  FDA  approval, 
seizure or recall of products, and criminal prosecution. 
Accordingly,  manufacturers  must  continue  to  spend 
time, money, and effort to maintain cGMP compliance.

including 

fines, 

The FDA and other federal regulatory agencies also 
closely regulate the promotion of drugs and biologics 
through, among other things, standards and regulations 
for  direct-to-consumer  advertising,  communications 
regarding  unapproved  uses, 
industry-sponsored 
scientific  and  educational  activities,  and  promotional 
activities  involving  the  Internet  and  social  media.  A 
product cannot be commercially promoted before it is 
approved. After approval, product promotion can include 
only those claims relating to safety and effectiveness 
that  are  consistent  with  the  labeling  approved  by  the 
FDA.  Healthcare  providers  are  permitted  to  prescribe 
drugs and biologics for uses not approved by the FDA 
and therefore not described in the product’s labeling - 
because  the  FDA  does  not  regulate  the  practice  of 
medicine.  However,  FDA  regulations  impose  stringent 
communications 
restrictions  on  manufacturers’ 
regarding such uses. Broadly speaking, a manufacturer 
may not promote a drug or biologic for an unapproved 
use,  but  may  engage  in  non-promotional,  balanced 
communication  regarding  such  uses  under  certain 
conditions.  Failure  to  comply  with  applicable  FDA 
requirements and restrictions in this area may subject 
a company to adverse publicity and enforcement action 
by the FDA, the Department of Justice, or the Office of 
the Inspector General (OIG) of the Department of Health 
and Human Services (HHS), as well as state authorities. 
Noncompliance could subject a company to a range of 
penalties  that  could  have  a  significant  commercial 
impact, including civil and criminal fines and agreements 
that materially restrict the manner in which a company 
promotes or distributes drug or biologic products.

Orphan Drug Designation in the U.S., the EU and Other 
Foreign Jurisdictions

Under  the  Orphan  Drug  Act,  the  FDA  may  grant 
orphan  drug  designation  to  drugs  and  biological 
products intended to treat a “rare disease or condition,” 
which generally is a disease or condition that affects 
fewer than two hundred thousand individuals in the U.S. 
Orphan  drug  designation  must  be  requested  before 
submitting a BLA or supplemental BLA. If the FDA grants 

15

orphan  drug  designation,  the  generic  identity  of  the 
therapeutic  agent  and  its  potential  orphan  use  are 
publicly disclosed by the FDA. Orphan drug designation 
does  not  convey  any  advantage  in,  or  shorten  the 
duration of, the regulatory review and approval process. 
If  a  product  which  has  an  orphan  drug  designation 
subsequently  receives  the  first  FDA  approval  for  that 
drug or biologic for the indication for which it has such 
designation,  the  product  is  entitled  to  an  orphan 
exclusivity period, in which the FDA may not approve any 
other applications to market the same drug or biologic 
for the same indication for seven years, except in limited 
circumstances, such as where the sponsor of a different 
version of the product is able to demonstrate that its 
product is clinically superior to the approved orphan drug 
product. This exclusivity does not prevent a competitor 
from obtaining approval to market a different product 
that treats the same disease or condition or the same 
product  to  treat  a  different  disease  or  condition.  The 
FDA can revoke a product’s orphan drug exclusivity under 
certain circumstances, including when the holder of the 
approved orphan drug application is unable to assure 
the availability of sufficient quantities of the drug to meet 
patient needs. A sponsor of a product application that 
has received an orphan drug designation is also granted 
tax  incentives  for  clinical  research  undertaken  to 
support the application. In addition, the FDA will typically 
coordinate with the sponsor on research study design 
for an orphan drug and may exercise its discretion to 
grant marketing approval on the basis of more limited 
product safety and efficacy data than would ordinarily 
be required.

In the EU, medicinal products: (a) that are used to 
treat or prevent life-threatening or chronically debilitating 
conditions that affect no more than five in ten thousand 
people in the EU when the application is made; or (b) that 
are used to treat or prevent life-threatening or chronically 
debilitating conditions and that, for economic reasons, 
would be unlikely to be developed without incentives; 
and  (c)  where  no  satisfactory  method  of  diagnosis, 
prevention  or  treatment  of  the  condition  concerned 
exists, or, if such a method exists, the medicinal product 
would be of significant benefit to those affected by the 
condition, may be granted an orphan designation. The 
application for orphan designation must be submitted 
to the EMA and approved before an application is made 
for  marketing  authorization  for  the  product.  Once 
authorized, orphan medicinal products are entitled to up 
to  ten  years  of  market  exclusivity  (which  may  be 
extended for an additional two years if pediatric data 
have  been  produced  in  accordance  with  an  agreed 
pediatric  investigational  plan).  During  this  ten  year 
period, with a limited number of exceptions, neither the 
competent  authorities  of  the  EU  Member  States,  the 
EMA, or the EC are permitted to accept applications or 
grant marketing authorization for other similar medicinal 
products with the same therapeutic indication. However, 
marketing  authorization  may  be  granted  to  a  similar 

medicinal  product  with  the  same  orphan  indication 
during  the  ten  year  period  with  the  consent  of  the 
marketing authorization holder for the original orphan 
medicinal product or if the manufacturer of the original 
orphan medicinal product is unable to supply sufficient 
quantities. Marketing authorization may also be granted 
to  a  similar  medicinal  product  with  the  same  orphan 
indication if this latter product is safer, more efficacious 
or  otherwise  clinically  superior  to  the  original  orphan 
medicinal product. The period of market exclusivity may, 
in  addition,  be  reduced  to  six  years  if  it  can  be 
demonstrated on the basis of available evidence that 
the criteria for orphan designation are no longer met or 
if the orphan medicinal product is sufficiently profitable 
not to justify maintenance of market exclusivity.

ULTOMIRIS has received orphan drug designation 
for the treatment of patients with PNH in the U.S., EU 
and  Japan,  and  for  the  subcutaneous  treatment  of 
patients  with  aHUS  in  the  U.S.  SOLIRIS  has  received 
orphan drug designation for (a) the treatment of PNH 
and  aHUS  in  the  U.S.,  the  EU,  and  in  several  other 
territories; (b) the prevention of delayed graft function 
in renal transplant patients in the U.S.; (c) the treatment 
of patients with gMG in the U.S., Japan, and the EU; (d) 
the  prevention  of  graft  rejection  and  delayed  graft 
rejection following solid organ transplantation in the EU 
and (e) and for the treatment of NMOSD in the U.S., EU, 
and Japan. In 2008, STRENSIQ received orphan drug 
designation for the treatment of patients with HPP in the 
U.S.  and  the  EU,  and  in  Japan  in  November  2014. 
Furthermore, in 2010, KANUMA received orphan drug 
designation for the treatment of LAL-D in the U.S. and 
the  EU.  As  noted  above,  orphan  drug  designation 
provides  certain  regulatory  and  filing  fee  advantages, 
including  market  exclusivity,  except 
limited 
circumstances, for several years after approval.

in 

Breakthrough Designation in the U.S.

that 

indicates 

Congress has created the Breakthrough Therapy 
designation  program  under  which  the  FDA  may  grant 
Breakthrough Therapy status to a drug intended for the 
treatment  of  a  serious  condition  when  preliminary 
clinical  evidence 
the  drug  may 
demonstrate  substantial  improvement  on  a  clinically 
significant  endpoint  over  existing  therapies.  The 
Breakthrough  Therapy  designation,  which  may  be 
requested by a sponsor when filing or amending an IND, 
is intended to facilitate and expedite the development 
and FDA review of a product candidate. Specifically, the 
Breakthrough  Therapy  designation  may  entitle  the 
sponsor to more frequent meetings with FDA during drug 
development, intensive guidance on clinical trial design, 
and expedited FDA review by a cross-disciplinary team 
comprised of senior managers. The designation does 
not guarantee a faster development or review time as 
compared to other drugs however, nor does it assure 
that the drug will obtain ultimate marketing approval by 
the  FDA.  Once  granted,  the  FDA  may  withdraw  this 

designation at any time if subsequent data no longer 
support the breakthrough therapy designation. We have 
received  Breakthrough  Therapy  designations 
for 
STRENSIQ  for  HPP  in  perinatal-,  infant-,  and  juvenile-
onset patients; and for KANUMA in the treatment of LAL-
D presenting in infants. It is difficult for us to predict the 
impact  that  these  designations  will  have  on  the 
development and FDA review of our products.

21st Century Cures Act (the Cures Act)

In  December  2016,  Congress  passed  the  Cures 
Act which included a number of provisions designed to 
speed  development  of  innovative  therapies,  provide 
funding authorization to the NIH, and provide funding for 
certain oncology-directed research. Because the FDA is 
still working to implement many aspects of the Cures 
Act, its potential effect on our business remains unclear 
with the exception of a provision requiring that we post 
our  policies  on  the  availability  of  expanded  access 
programs  for  individuals.  In  addition,  the  Cures  Act 
includes  requiring  the  FDA  to  assess  and  publish 
guidance on the use of novel clinical trial designs, the 
use of real world evidence in applications, the availability 
of summary level review for supplemental applications 
for  certain  indications,  and  the  qualification  of  drug 
development tools. Because these provisions allow the 
FDA to spend several years developing these policies, 
the effect on us could be delayed. At this time, we cannot 
anticipate what effect these future policies may have on 
our business.

The Cures Act also authorizes $1,800.0 in funding 
for the “Cancer Moonshot” initiative (the Initiative) to 
be  run  by  the  NIH.  The  Initiative’s  strategic  goals 
encourage inter-agency cooperation and fund research 
and innovation to catalyze new scientific breakthroughs, 
bring  new  therapies  to  patients,  and  strengthen 
prevention  and  diagnosis.  The  Initiative  aims  to 
stimulate drug development through the creation of a 
public-private partnership with 20 to 30 pharmaceutical 
and  biotechnology  companies  to  expedite  cancer 
researchers’  access  to  investigational  agents  and 
approved drugs. This partnership is designed to permit 
researchers to obtain drugs and other technologies from 
a  preapproved  “formulary”  list  without  having  to 
negotiate  with  each  company  for  individual  research 
projects. We will monitor these developments but cannot 
currently  assess  how  the  Initiative  may  impact  our 
business.

Foreign Regulation of Drug Development and Approval

In addition to regulations in the U.S., we are subject 
to a variety of foreign regulatory requirements including 
those  governing  human  clinical  trials,  marketing 
approval, and post-marketing regulation for drugs. The 
foreign regulatory approval process includes all of the 
risks associated with FDA approval set forth above, as 
well as additional country-specific regulations. Whether 
or not we obtain FDA approval for a product, we must 

16

obtain  approval  of  a  product  by  the  comparable 
regulatory authorities of foreign countries before we can 
commence clinical trials or marketing of the product in 
those  countries.  Approval  by  one  regulatory  authority 
does  not  ensure  approval  by  regulatory  authorities  in 
other  jurisdictions.  The  approval  process  varies  from 
country to country, can involve additional testing beyond 
that required by FDA, and may be longer or shorter than 
that  required  for  FDA  approval.  The  requirements 
governing the conduct of clinical trials, product licensing, 
pricing, promotion, and reimbursement vary greatly from 
country to country.

involves 

Under the EU regulatory system, we may submit 
applications for marketing authorizations either under a 
centralized,  decentralized,  or  mutual 
recognition 
marketing  authorization  procedure.  The  centralized 
procedure provides for the grant of a single marketing 
authorization for a medicinal product by the EC on the 
basis of a positive opinion by the EMA and is mandatory 
for  certain  categories  of  medicinal  products,  such  as 
orphan  medicinal  products.  A  centralized  marketing 
authorization is valid for all EU Member States and the 
European  Economic  Area  states.  The  decentralized 
procedure and the mutual recognition procedure apply 
between  EU  Member  States.  The  decentralized 
marketing  authorization  procedure 
the 
submission of an application for marketing authorization 
to the competent authority of all EU member states in 
which  the  product  is  to  be  marketed.  One  national 
competent  authority,  selected  by 
the  applicant, 
assesses the application for  marketing  authorization. 
The  competent  authorities  of  the  other  EU  Member 
States  are  subsequently  required  to  grant  marketing 
authorization  for  their  territory  on  the  basis  of  this 
assessment, except where grounds of potential serious 
risk  to  public  health  require  this  authorization  to  be 
refused. The mutual recognition procedure provides for 
mutual 
recognition  of  marketing  authorizations 
delivered by the national competent authorities of EU 
Member States by the competent authorities of other 
EU Member States. The holder of a national marketing 
authorization  may  submit  an  application  to  the 
competent authority of an EU member state requesting 
that this authority recognize the marketing authorization 
delivered  by  the  competent  authority  of  another  EU 
member state for the same medicinal product. The EC 
may agree upon recommendation of the EMA to grant 
for  medicines  designated  as  orphan  medicines  a 
(i) conditional marketing authorization in the interest of 
public  health  under  certain  conditions;  namely  that 
unmet  medical  needs  will  be  fulfilled,  the  benefit-risk 
balance of the product is positive, the benefit to public 
health of the medicinal product’s immediate availability 
on the market outweighs the risks due to need for further 
data  and  it  is  likely  that  the  applicant  will  be  able  to 
provide  comprehensive  data;  or 
(ii)  marketing 
authorization under “exceptional circumstances” when 
the  applicant  can  show  that  it  is  unable  to  provide 

17

comprehensive data on the efficacy and safety under 
normal  conditions  of  use  and  subject  to  specific 
procedures  being  introduced.  This  may  arise  in 
particular when the intended indications are very rare, 
in  the  present  state  of  scientific  knowledge,  it  is  not 
possible to provide comprehensive information, or when 
generating data may be contrary to generally accepted 
ethical principles.

Similarly to the U.S., both marketing authorization 
holders and manufacturers of medicinal products are 
subject  to  comprehensive  regulatory  oversight  by  the 
EMA and the competent authorities of the individual EU 
Member  States  both  before  and  after  grant  of  the 
manufacturing  and  marketing  authorizations.  This 
includes control of compliance by the companies within 
the  EU  legal  framework  (i.e.,  GCP,  GLP,  cGMP  and 
pharmacovigilance rules, which govern quality control of 
the manufacturing process and require documentation 
policies  and  procedures).  We  and  our  third  party 
manufacturers are required under regulations to ensure 
that all of our processes, methods, and equipment are 
compliant with GCP, GLP, cGMP and pharmacovigilance 
rules. The EMA and national competent authorities may 
arrange inspections to ensure that we adhere to these 
principles  and  regulations.  Any  adverse  findings  from 
such inspections, depending on their severity, may result 
in  significant  delays 
in  obtaining  a  marketing 
authorization,  may  impose  penalties  or  may  result  in 
other action by regulatory authorities.

Failure by us or by any of our third party partners, 
including suppliers, manufacturers, and distributors to 
comply with EU laws and the related national laws of 
individual EU Member States governing the conduct of 
clinical 
trials,  manufacturing  approval,  marketing 
authorization  of  medicinal  products,  pre-approval 
promotion  of  products,  reporting  of  adverse  health 
events,  both  before  and  after  grant  of  marketing 
authorization,  and  marketing/promotion  of  such 
products following grant of authorization may result in 
administrative,  civil,  or  criminal  penalties.  These 
penalties could include delays in or refusal to authorize 
the  conduct  of  clinical  trials  or  to  grant  marketing 
authorization, product withdrawals and recalls, product 
seizures,  suspension,  or  variation  of  the  marketing 
authorization, total or partial suspension of production, 
distribution, manufacturing, or clinical trials, operating 
restrictions, injunctions, suspension of licenses, fines, 
and criminal penalties.

The EU has had an established regulatory pathway 
for  biosimilars  since  2005  and  has  approved  several 
biosimilar products. In addition, in February 2017 the 
EMA launched a pilot project with the aim of providing 
scientific advice to companies for the development of 
new biosimilar products.

The approval of a biosimilar of one of our products 
marketed in the EU could have a material impact on our 
business. The biosimilar may be less costly to bring to 

market,  may  be  priced  significantly  lower  than  our 
products,  and  result  in  a  reduction  in  the  pricing  and 
reimbursement of our products.

Pharmaceutical Pricing and Reimbursement 

Sales  of  pharmaceutical  products  depend  in 
significant  part  on  the  extent  of  coverage  and 
reimbursement  from  third  party  payers,  including 
government programs such as Medicare and Medicaid 
in the U.S, as well as private health insurers. Third party 
payers  are  sensitive  to  the  cost  of  drugs  and  are 
increasingly  seeking  to  implement  cost  containment 
measures to control, restrict access to, or influence the 
purchase  of  drugs,  biologics,  and  other  health  care 
products and services. For example, governments may 
regulate  reimbursement,  pricing,  and  coverage  of 
products in order to control costs or to affect utilization 
levels  of  certain  products.  In  addition,  private  health 
insurance plans may restrict coverage of some products, 
such  as  by  using  drug  formularies  under  which  only 
select drugs or uses of select drugs are covered, through 
the  implementation  of  variable  patient  co-payment 
obligations  that  make  non-preferred  drugs  more 
expensive  for  patients,  and  by  employing  utilization 
management controls, such as requirements for prior 
authorization or prior failure on another type of treatment 
before the insurer will cover and reimburse a particular 
therapy. Payers may especially impose these obstacles 
to coverage for higher-priced drugs such as those we 
sell. Consequently, all of our products may be subject 
to  payer-driven 
rendering  patients 
responsible for a higher percentage of the total cost of 
drugs  in  the  outpatient  setting.  This  can  lower  the 
demand for our products if the increased patient cost-
sharing obligations are more than patients can afford.

restrictions, 

Medicare is a U.S. federal government insurance 
program that covers individuals aged 65 years or older, 
as well as individuals of any age with certain disabilities, 
and  individuals  with  end-stage  renal  disease.  Our 
products  are  primarily  reimbursed  by  Medicare  under 
Medicare  Part  B,  which  generally  covers  physician 
services and outpatient care, including some outpatient 
prescription  drugs  under  limited  conditions,  and 
Medicare  Part  D,  which  provides  an  outpatient 
prescription drug benefit for Medicare beneficiaries. 

Generally  speaking,  Medicare  Part  B  provides 
limited  coverage  of  certain  outpatient  drugs  and 
biologics  that  are  reasonable  and  necessary  for 
diagnosis or treatment of an illness or injury. Under Part 
B, reimbursement for most drugs is based on a fixed 
percentage  above  the  applicable  product’s  average 
sales price (ASP). Manufacturers calculate ASP based 
on a statutory formula and must report ASP information 
to  the  Centers  for  Medicare  and  Medicaid  Services 
(CMS), the federal agency within HHS that administers 
Medicare and the Medicaid Drug Rebate Program, on a 
quarterly basis. Under the Medicare Prescription Drug, 
Improvement, and Modernization Act of 2003, Medicare 

pays physicians and suppliers ASP + 6.0% for most Part 
B-covered drugs and biologics (Medicare payments for 
ULTOMIRIS  will  also  be  based  on  the  ASP  formula 
commencing  with  the  period  two  quarters  after 
approval). Medicare payment for separately payable Part 
B  drugs  reimbursed  through  the  hospital  outpatient 
prospective  payment  system  is  generally  under  the 
discretion of CMS, meaning it can be changed without 
legislative  action 
from  Congress.  The  current 
reimbursement rate for most separately payable Part B 
drugs used in the hospital outpatient setting is ASP plus 
6.0%. One exception, however, is that, effective January 
1, 2018, Medicare pays 340B hospital covered entities 
ASP minus 22.5% for separately payable Part-B covered 
drugs and biologics that were purchased under the 340B 
Program  in  an  outpatient  clinic  setting,  as  discussed 
further below. In addition, the sequester that is currently 
in  place  through  2027,  reduces  payments  providers 
receive for Part B-Covered drugs by 1.6%, which results 
in  a  net  payment  equivalent  to  ASP  plus  4.3%.  The 
sequester affects other Medicare payments and is also 
discussed in more detail below. In both settings (i.e., 
physician office and hospital outpatient), the amount of

Medicare Part D is an outpatient prescription drug 
benefit  available  to  all  Medicare  beneficiaries.  It  is  a 
benefit that is implemented through private insurance 
plans  under  contractual  arrangements  between  the 
plans  and 
to 
pharmaceutical  coverage 
through  private  health 
insurance,  Part  D  plans  develop  formularies,  impose 
utilization  controls  (such  as  prior  authorization,  step 
therapy,  and  quantity  limits),  and  negotiate  discounts 
from  drug  manufacturers.  Because  of  this,  the  list  of 
prescription  drugs  covered  by  Part  D  plans  varies  by 
plan. However, with limited exceptions, individual plans 
are  required  by  statute  to  cover  certain  therapeutic 
categories and classes of drugs or biologics and to have 
at least two drugs in each unique therapeutic category 
or class.

Our products can also be provided under Medicare 
Parts A and C (Medicare Advantage). Medicare Part A 
generally covers inpatient hospital benefits. Hospitals 
typically receive a single payment for an inpatient stay 
depending on the Medicare Severity Diagnosis Related 
Group (MS-DRG) to which the inpatient stay is assigned. 
The MS-DRG for a hospital inpatient stay varies based 
on  the  patient’s  condition.  Hospitals  generally  do  not 
receive  separate  payment  for  drugs  and  biologics 
administered  to  patients  during  an  inpatient  hospital 
stay.  As  a  result,  hospitals  may  not  have  a  financial 
incentive  to  utilize  our  products  for  inpatients  where 
lower  cost  alternative  therapies  are  available.  Finally, 
Medicare beneficiaries can receive their Part A, B, and 
D benefits through a Medicare Advantage organization 
plan that is administered by a private insurance company 
pursuant to Medicare Part C. Similar to private health 

18

insurance plan, Medicare Advantage organization plans 
negotiate  discounts  with  health  care  providers  and 
implement utilization controls, including, most notably, 
step therapy for Part B drugs beginning January 1, 2019.

Beginning April 1, 2013, the Budget Control Act of 
2011,  Pub.  L.  No.  112-25,  as  amended,  requires 
Medicare payments for all items and services, including 
drugs and biologics, to be reduced by up to 2.0% under 
sequestration  (i.e.,  automatic  spending  reductions, 
calculated each year by the Office of Management and 
Budget).  Subsequent  legislation  extended  the  2.0% 
reduction, on average, to 2027. This 2.0% reduction in 
Medicare  payments  affects  all  Parts  of  the  Medicare 
program  and  could  impact  sales  of  our  products. 
Additional sequestration orders could also be triggered, 
potentially resulting in up to a 4% reduction in Medicare 
payments.

Pursuant to the Medicaid Drug Rebate Statute (42 
U.S.C. § 1396r-8(a)(1)), we are required to participate 
in the Medicaid Drug Rebate Program in order for federal 
payment to be available for our products under Medicaid 
and Medicare Part B. Medicaid is a government health 
insurance  program  for  eligible  low-income  adults, 
children,  families,  pregnant  women,  and  people  with 
certain disabilities. It is jointly funded by the federal and 
state governments, and it is administered by individual 
states  within  parameters  established  by  the  federal 
government. As a result, coverage and reimbursement 
requirements for drugs and biologics vary by state. For 
example, drugs and biologics may be covered under the 
medical  or  pharmacy  benefit,  and  state  Medicaid 
programs may impose different utilization management 
controls,  such  as  prior  authorization,  step  therapy,  or 
quantity limits on drugs and biologics, subject to federal 
limitations  for  such  controls.  But  all  states  must 
generally  provide  coverage  and  reimbursement  for  a 
manufacturer’s covered outpatient drugs, as that term 
is  defined  by  applicable  law,  if  a  manufacturer 
participates in the Medicaid Drug Rebate Program. 

Under the Medicaid Drug Rebate Program, we are 
required to, among other things, pay a rebate to each 
state Medicaid program for quantities of our products 
utilized on an outpatient basis (with some exceptions) 
that are dispensed to Medicaid beneficiaries and paid 
for by a state Medicaid program. Medicaid Drug Rebate 
Program  Rebates  are  calculated  using  a  statutory 
formula, state-reported utilization data, and pricing data 
that are calculated and reported by us on a monthly and 
quarterly basis to CMS. These data include the average 
manufacturer  price  and,  in  the  case  of  innovator 
products,  the  best  price  for  each  drug.  As  further 
described  below  under  “U.S.  Healthcare  Reform  and 
Other U.S. Healthcare Laws,” the Patient Protection and 
Affordable Care Act, as amended by the Health Care and 
Education Reconciliation Act of 2010 (collectively, the 
PPACA), made significant changes to the Medicaid Drug 
Rebate Program that could negatively impact our results 
of operations. 

19

In  addition  to  participating  in  the  Medicaid  Drug 
Rebate Program, federal law requires manufacturers like 
us  to  participate  in  the  Public  Health  Service’s  340B 
drug  pricing  program  in  order  for  federal  funds  to  be 
available for the manufacturer’s drugs under Medicaid 
and Medicare Part B. The 340B drug pricing program 
requires participating manufacturers to agree to charge 
statutorily-defined  covered  entities  no  more  than  the 
340B  “ceiling  price”  for  the  manufacturer’s  covered 
outpatient  drugs.  These  340B  covered  entities  only 
include  health  care  organizations  that  have  certain 
federal  designations  or  receive  funding  from  specific 
federal  programs,  including  Federally  Qualified  Health 
Centers, Ryan White HIV/AIDS Program grantees, and 
certain types of hospitals and specialized clinics, as well 
as certain hospitals that serve a disproportionate share 
of  low-income  patients.  PPACA  expanded  the  340B 
program to include additional types of covered entities: 
certain children’s hospitals, certain free-standing cancer 
hospitals, critical access hospitals, rural referral centers 
and  sole  community  hospitals,  each  as  defined  by 
PPACA. However, “orphan drugs” i.e., those designated 
under  section  526  of  the  FDCA,  such  as  each  of  our 
products  that  have  received  market  authorization  are 
exempted from the ceiling price requirements for these 
newly-eligible entities when used for the rare disease or 
condition for which they received an orphan designation. 
The 340B ceiling price is calculated using a statutory 
formula, which is based on the average manufacturer 
price and rebate amount for the covered outpatient drug 
as calculated under the Medicaid Drug Rebate Program, 
and in general, products subject to the Medicaid Drug 
Rebate  Program  are  also  subject  to  the  340B  ceiling 
price calculation and discount requirement. Any changes 
to the definition of Medicaid average manufacturer price 
and the Medicaid rebate amount also could affect our 
340B ceiling price calculation for our products and could 
negatively impact our results of operations. In addition, 
after  multiple  delays,  the  final  rule  implementing  civil 
monetary penalties against manufacturers for instances 
of overcharging 340B covered entities became effective 
on January 1, 2019. Accordingly, we could be subject to 
such penalties if the government finds that we knowingly 
and intentionally overcharged a 340B covered entity.

Federal  law  requires  that  for  a  company  to  be 
eligible to have its products paid for with federal funds 
under the Medicaid and Medicare Part B programs as 
well as to be purchased by certain federal agencies and 
grantees, it also must participate in the Department of 
Veterans  Affairs  (VA)  Federal  Supply  Schedule  (FSS) 
pricing program. To participate, we are required to enter 
into an FSS contract and other agreements with the VA 
for our products, which qualify as “covered drugs.” Under 
these agreements, we must make our products available 
to  the  “Big  Four”  federal  agencies  the  VA,  the 
Department of Defense (DoD), the Public Health Service 
(including  the  Indian  Health  Service),  and  the  Coast 
Guard at pricing that is capped pursuant to a statutory 

federal  ceiling  price,  or  FCP,  formula  set  forth  in 
Section 603 of the Veterans Health Care Act of 1992 
(VHCA). The FCP is based on a weighted average non-
federal average manufacturer price (Non-FAMP), which 
manufacturers are required to report on a quarterly and 
annual basis to the VA. Pursuant to the VHCA, knowing 
provision of false information in connection with a Non-
FAMP filing can subject a manufacturer to a penalty for 
each item of false information and could result in other 
potential  liability  as  well,  including  liability  under  the 
False  Claims  Act  (which  is  discussed  in  more  detail 
below).

FSS contracts are federal procurement contracts 
that include standard government terms and conditions, 
separate  pricing  for  each  product,  and  extensive 
disclosure and certification requirements. All items on 
FSS contracts are subject to a standard FSS contract 
clause that requires FSS contract price reductions under 
certain circumstances where pricing is reduced to an 
agreed “tracking customer.” Further, in addition to the 
“Big Four” agencies, all other federal agencies and some 
non-federal entities are authorized to purchase off FSS 
contracts. FSS contractors are permitted to charge FSS 
purchasers other than the Big Four agencies “negotiated 
pricing” for covered drugs that is not capped by the FCP; 
instead,  such  pricing  is  negotiated  based  on  a 
mandatory  disclosure  of  the  contractor’s  commercial 
“most favored customer” pricing. We offer dual pricing 
on our FSS contract.

In addition, pursuant to regulations issued by the 
DoD to implement Section 703 of the National Defense 
Authorization  Act  for  Fiscal  Year  2008,  each  of  our 
covered  drugs  is  listed  on  an  agreement  with  the 
Defense  Health  Agency  (DHA)  under  which  we  have 
agreed to honor the “Big Four” pricing for our products 
when they are dispensed to TRICARE beneficiaries by 
TRICARE retail network pharmacies. More specifically, 
we have agreed to provide rebates (or refunds) on such 
utilization. Companies are required to enter into a DHA 
Agreement for “covered drug” products in order for the 
covered drug to be eligible for DoD formulary inclusion 
and  available 
to  TRICARE  beneficiaries  without 
preauthorization. The formula for determining the rebate 
is established in the regulations and our DHA agreement 
and is based on the difference between the annual Non-
FAMP  and  the  FCP  (as  described  above,  these  price 
points  are  required  to  be  calculated  by  us  under  the 
VHCA).

As  noted  in  the  foregoing,  pricing  and  rebate 
calculations  vary  among  products  and  programs.  The 
calculations can be very complex and are often subject 
to  interpretation  by  us,  governmental  or  regulatory 
agencies and the courts. We cannot assure you that our 
submissions  will  not  be  found  by  CMS  or  other 
governmental agencies to be incomplete or incorrect. 
Governmental  agencies  may  also  make  changes  in 
program interpretations, requirements or conditions of 
participation, some of which may have implications for 

20

amounts previously estimated or paid. For example, if 
we become aware that certain Medicaid Drug Rebate 
Program price reporting for a prior quarter was incorrect, 
or has changed as a result of recalculation of the pricing 
data, we are obligated to resubmit the corrected data 
for  a  period  not  to  exceed  twelve  quarters  from  the 
quarter in which the data originally were due, and CMS 
may consider restatements for earlier periods as well 
depending on the circumstance. Such restatements and 
recalculations increase our costs for complying with the 
laws  and  regulations  governing  the  Medicaid  Drug 
Rebate Program. Any corrections to our Medicaid rebate 
calculations could result in an increase or decrease in 
our rebate liability for past quarters, depending on the 
nature of the correction. Price recalculations also may 
affect the ceiling price at which we are required to offer 
our products to certain covered entities under the 340B 
drug pricing program.

Any failure to comply with these price reporting and 
rebate payment obligations could negatively impact our 
financial results. Civil monetary penalties can be applied 
if we are found to have knowingly submitted any false 
price information to the government, if we are found to 
have made a misrepresentation in the reporting of our 
average sales price, or if we fail to submit the required 
price data on a timely basis. Such conduct also could 
be  grounds  for  CMS  to  terminate  our  Medicaid  drug 
rebate agreement, in which case federal payments may 
not be available under Medicaid or Medicare Part B for 
our covered outpatient drugs, as well as provide a basis 
for other potential liability under other federal laws such 
as the False Claims Act.

Payers  also  are  increasingly  considering  new 
metrics as the basis for reimbursement rates, such as 
ASP, average manufacturer price, and actual acquisition 
cost.  The  existing  data  for  reimbursement  based  on 
these  metrics  is  relatively  limited,  although  certain 
states have begun to survey acquisition cost data for 
the purpose of setting Medicaid reimbursement rates. 
CMS surveys and publishes retail community pharmacy 
acquisition  cost  information  in  the  form  of  National 
Average  Drug  Acquisition  Cost  files  to  provide  state 
Medicaid agencies with a basis of comparison for their 
own  reimbursement  and  pricing  methodologies  and 
rates. It may be difficult to project the impact of these 
evolving reimbursement mechanics on the willingness 
of payers to cover our products.

Further,  in  the  U.S.,  there  is  increased  focus  on 
drug pricing, and the President, policy officials (including 
the FDA) and lawmakers have expressed a clear interest 
in efforts to reduce prices for drugs and biologics, further 
increase 
transparency  around  prices  and  price 
increases, lower out-of-pocket costs for consumers, and 
decrease spending on drugs by government programs. 
In  addition,  members  of  Congress  have  launched  an 
investigation 
the 
prescription drug industry (and hearings may be held in 
2019 in connection with this investigation). We expect 

the  pricing  practices  of 

into 

regulatory  changes  and  continued  Congressional 
investigations  and  negative  media  attention  in  the 
coming  months  with  respect  to  drugs  reimbursed  by 
federal healthcare programs, like ours, which could have 
a negative impact on our operations.

to  ensure 

In addition, in some foreign countries, the proposed 
pricing for a drug must be approved before it may be 
requirements 
lawfully  marketed.  Moreover, 
governing drug pricing and reimbursement vary widely 
from country to country. For example, in the EU, the sole 
legal instrument at the EU level governing the pricing 
and  reimbursement  of  medicinal  products  is  Council 
Directive  89/105/EEC 
(the  Price  Transparency 
Directive). The aim of the Price Transparency Directive 
is 
reimbursement 
that  pricing  and 
mechanisms  established  in  EU  Member  States  are 
transparent  and  objective,  do  not  hinder  the  free 
movement and trade of medicinal products in the EU 
and do not hinder, prevent or distort competition on the 
market.  The  Price  Transparency  Directive  does  not, 
however, provide any guidance concerning the specific 
criteria on the basis of which pricing and reimbursement 
decisions  are  to  be  made  in  individual  EU  Member 
States. Neither does it have any direct consequence for 
pricing  or  levels  of  reimbursement  in  individual  EU 
Member States. Pricing of prescription only medicinal 
products is a national prerogative. Therefore the relevant 
national authorities of the individual EU Member States 
are free to restrict the range of medicinal products for 
which their national health insurance systems provide 
reimbursement  and  to  control  the  prices  and/or 
reimbursement of medicinal products for human use. 
Some  individual  EU  Member  States  adopt  policies 
according  to  which  a  specific  price  or  level  of 
reimbursement is approved for the medicinal product. 
Other EU Member States adopt a system of reference 
pricing, basing the price or reimbursement level in their 
territory either, on the pricing and reimbursement levels 
in other countries, or on the pricing and reimbursement 
levels  of  medicinal  products  intended  for  the  same 
therapeutic indication. Furthermore, some EU Member 
States  impose  direct  or  indirect  controls  on  the 
profitability  of  the  company  placing  the  medicinal 
product on the market.

Health Technology Assessment (HTA) of medicinal 
products is becoming an increasingly common part of 
the pricing and reimbursement procedures in some EU 
Member  States.  These  countries  include  the  United 
Kingdom,  France,  Germany  and  Sweden.  The  HTA 
process in the EU Member States is governed by the 
national laws of these countries. HTA is the procedure 
according to which the assessment of the public health 
impact,  therapeutic  impact  and  the  economic  and 
societal impact of the use of a given medicinal product 
in  the  national  healthcare  systems  of  the  individual 
country  is  conducted.  HTA  generally  focuses  on  the 
clinical efficacy and effectiveness, safety, cost, and cost-
effectiveness of individual medicinal products as well

healthcare  system.  Those  elements  of  medicinal 
products  are  compared  with  other  treatment  options 
available on the market.

for 

The outcome of HTA may influence the pricing and 
reimbursement status for specific medicinal products 
within individual EU Member States. The extent to which 
pricing and reimbursement decisions are influenced by 
the HTA of a specific medicinal product vary between 
the EU Member States.

In  2011,  Directive  2011/24/EU  was  adopted  at 
the EU level. This Directive concerns the application of 
patients’ rights in cross-border healthcare. The Directive 
is intended to establish rules for facilitating access to 
safe and high-quality cross-border healthcare in the EU. 
Pursuant to Directive 2011/24/EU, a voluntary network 
of national authorities or bodies responsible for HTA in 
the individual EU Member States was established. The 
purpose of the network is to facilitate and support the 
exchange of scientific information concerning HTAs. This 
could  lead  to  harmonization  of  the  criteria  taken  into 
account  in  the  conduct  of  HTA  between  EU  Member 
States  in  pricing  and  reimbursement  decisions  and 
negatively  impact  price  in  at  least  some  EU  Member 
States.

On a continuous basis, we engage with appropriate 
authorities  in  individual  countries  on  the  operational, 
reimbursement, price approval and funding processes 
that are separately required in each country.

Fraud and Abuse 

Pharmaceutical companies participating in federal 
healthcare  programs  like  Medicare  or  Medicaid  are 
subject to various U.S. federal and state laws pertaining 
to healthcare “fraud and abuse,” including anti-kickback 
and  false  claims  laws.  Violations  of  U.S.  federal  and 
state  fraud  and  abuse  laws  may  be  punishable  by 
criminal,  civil  and  administrative  sanctions,  including 
fines, damages, civil monetary penalties and exclusion 
from  participation  in  federal  healthcare  programs 
(including  Medicare  and  Medicaid).  Applicable  U.S. 
statutes, include, but are not limited to, the following:

• The  federal  Anti-Kickback  Statute  prohibits, 
among  other  things,  knowingly  and  willfully 
soliciting,  offering,  receiving,  or  paying  any 
remuneration, directly or indirectly, in cash or in 
kind, to induce or reward purchasing, ordering or 
arranging for or recommending the purchase or 
order of any item or service for which payment 
may be made, in whole or in part, under a federal 
healthcare  program  such  as  Medicare  and 
Medicaid. Liability may be established without a 
person or entity having actual knowledge of the 
federal Anti-Kickback Statute or specific intent 
to violate it. This statute has been interpreted 
to  apply  broadly  to  arrangements  between 
pharmaceutical manufacturers on the one hand 

and  individuals  such  as  prescribers,  patients, 
purchasers  and  formulary  managers  on  the 
other.  In  addition,  PPACA  amended  the  Social 
Security Act to provide that the government may 
assert that a claim including items or services 
resulting  from  a  violation  of  the  federal  Anti-
Kickback  Statute  constitutes  a 
false  or 
fraudulent claim for purposes of the federal civil 
False Claims Act (which is discussed below). A 
conviction  for  violation  of  the  Anti-Kickback 
Statute  results  in  criminal  fines  and  requires 
in 
mandatory  exclusion 
federal health care programs. Although there are 
a number of statutory exceptions and regulatory 
safe harbors to the federal Anti-Kickback Statute 
that protect certain common, industry practices 
from  prosecution,  the  exceptions  and  safe 
harbors are drawn narrowly, and arrangements 
may be subject to scrutiny or penalty if they do 
not  fully  satisfy  all  elements  of  an  available 
exception  or  safe  harbor.  The  discount  safe 
harbor is currently the subject of possible reform. 
Any  changes  to  the  discount  safe  harbor  may 
cause us to review our arrangements and pricing 
strategies with payers.

• The federal civil False Claims Act (FCA) imposes 
civil penalties against individuals or entities for, 
among  other  things,  knowingly  presenting,  or 
causing to be presented, claims for payment to 
the government that are false or fraudulent, or 
knowingly making, using or causing to be made 
or used a false record or statement material to 
such  a  false  or  fraudulent  claim,  or  knowingly 
concealing or knowingly and improperly avoiding, 
decreasing,  or  concealing  an  obligation  to  pay 
money to the federal government. This statute 
also  permits  a  private  individual  acting  as  a 
“whistleblower” to bring actions on behalf of the 
federal government alleging violations of the FCA 
and  to  share  in  any  monetary  recovery.  FCA 
liability is potentially significant in the healthcare 
industry because the statute provides for treble 
damages  and  mandatory  penalties  of  eleven 
thousand one hundred eighty-one to twenty-two 
thousand three hundred sixty-three dollars per 
false claim or statement for penalties assessed 
after January 29, 2018, with respect to violations 
occurring after November 2, 2015 (and penalties 
of five thousand five hundred to eleven thousand 
dollars  with  respect  to  violations  occurring 
before  that  date).  Government  enforcement 
agencies  and  private  whistleblowers  have 
investigated  pharmaceutical  companies  for  or 
asserted liability under the FCA for a variety of 
alleged inappropriate promotional and marketing 
activities, including those involving the provision 
of  free  product  or  other  items  of  value  to 
customers, certain financial arrangements with

pricing  information,  and  purported  “off-label” 
promotion of products, among other things.

representations, or make or use any materially

program;  (3)  violations  of  the  federal  Anti-

• The majority of states also have statutes similar 
to the federal Anti-Kickback Statute and FCA that 
apply to items and services reimbursed under 
Medicaid and other state health care programs, 
or,  in  several  states,  apply  regardless  of  the 
payer.

among others, to track and report annually to the 
federal government (for disclosure to the public)

healthcare providers, and restrict the ability of 
manufacturers to offer co-pay support to patients 
for certain prescription drugs. Some states and 
cities require identification or licensing of state

passed state laws require disclosures related to 
state  agencies  and/or  commercial  purchasers 
with  respect  to  certain  price  increases  that 
exceed a certain level as identified in the relevant 
statutes.  Many  of  these  laws  and  regulations

implementation, our reporting actions could be 
subject to the penalty provisions of the pertinent

the discussion below in the “Risk Factors” section and 
Note  11  “Commitments  and  Contingencies”  to  the 
consolidated financial statements included elsewhere 
in this Annual Report on Form 10-K for additional details 
regarding  this  investigation.  Similar  investigations  of 
other  pharmaceutical  companies  have  resulted  in 
significant  civil  and  criminal  settlements.  Efforts  to 
ensure  that  our  business  arrangements  continue  to 
comply with applicable healthcare laws and regulations 
could be costly.

Outside the U.S., other countries have 

implemented similar laws and regulations relating to 
fraud and abuse in the sale of pharmaceutical 
products and requirements for disclosure of financial 
interactions with healthcare providers and additional 
countries may consider or implement such laws.

U.S. Healthcare Reform and Other U.S. and 
International Healthcare Laws 

PPACA  was  adopted  in  the  U.S.  in  March  2010. 
This  law  substantially  changes  the  way  healthcare  is 
financed in the U.S. by both governmental and private 
insurers, and significantly impacts the pharmaceutical 
industry. PPACA contains a number of provisions that 
have  and  are  expected  to  impact  our  business  and 
operations.  Changes  that  may  affect  our  business 
include those governing enrollment in federal healthcare 
programs,  reimbursement  changes,  rules  regarding 
prescription drug benefits under the health insurance 
exchanges, expansion of the 340B program, expansion 
of state Medicaid programs, and 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.

PPACA  contains  several  provisions  that  have  or 
could potentially have an impact on our business. PPACA 
made significant changes to the Medicaid Drug Rebate 
Program.  Effective  March 23,  2010,  rebate  liability 
expanded  from  fee-for-service  Medicaid  utilization  to 
include  the  utilization  of  Medicaid  managed  care 
organizations as well. With regard to the amount of the 
rebates owed, PPACA increased the minimum Medicaid 
rebate percentage from 15.1% to 23.1% of the average 
manufacturer  price  for  most  innovator  products; 
changed  the  calculation  of  the  rebate  for  certain 
innovator  products  that  qualify  as  line  extensions  of 
existing drugs; and capped the total rebate amount for 
innovator drugs at 100.0% of the average manufacturer 

23

 
price.  In  addition,  PPACA  and  subsequent  legislation 
changed the definition of average manufacturer price. 
Finally, PPACA requires pharmaceutical manufacturers 
of  branded  prescription  drugs  to  pay  a  branded 
prescription drug fee to the federal government. Each 
individual pharmaceutical manufacturer pays a prorated 
share of the aggregate branded prescription  drug  fee 
paid by all covered entities ($2,800 in 2019 and each 
ensuing  year),  based  on,  among  other  things,  its 
applicable  branded  prescription  drug  sales  to  certain 
federal programs identified in the law. Sales of “orphan 
drugs” are excluded from this fee. “Orphan drugs” are 
specifically  defined  for  purposes  of  the  fee.  For  each 
indication  approved  by  the  FDA  for  the  drug,  such 
indication must have been designated as orphan by the 
FDA under section 526 of the FDCA, an orphan drug tax 
credit under section 45C of the Internal Revenue Code 
of  1986  (Internal  Revenue  Code)  must  have  been 
claimed with respect to such indication, and such tax 
credit  must  not  have  been  disallowed  by  the  Internal 
Revenue Service (IRS). Finally, the FDA must not have 
approved  the  drug  for  any  indication  other  than  an 
orphan indication for which a section 45C orphan drug 
tax  credit  was  claimed  (and  not  disallowed).  In  early 
2016, CMS issued a final regulation to implement the 
changes to the Medicaid Drug Rebate Program under 
PPACA, which became effective on April 1, 2016. The 
issuance  of  the  final  regulation,  as  well  as  any  other 
regulations  and  coverage  expansion  by  various 
governmental  agencies  relating  to  the  Medicaid  Drug 
Rebate  Program,  has  increased  and  will  continue  to 
increase our costs and the complexity of compliance, 
has  been  and  will  continue  to  be  time-consuming  to 
implement, and could have a material adverse effect on 
our results of operations, particularly if CMS challenges 
the approach we take in our implementation of the final 
rule.

Additional  provisions  of  PPACA  may  negatively 
affect  manufacturer’s  revenues  in  the  future.  For 
example,  as  part  of  PPACA’s  provisions  closing  a 
coverage gap that currently exists in the Medicare Part 
D prescription drug program (commonly known as the 
“donut  hole”),  manufacturers  of  branded  prescription 
drugs  and  biologics  are  required  to  provide  a  50.0% 
discount on branded prescription drugs  and  biologics 
dispensed to beneficiaries within this donut hole. This 
discount  was  recently  increased  to  70.0%,  beginning 
January 1, 2019, by the Bipartisan Budget Act of 2018.

As noted above, PPACA also expanded the Public 
Health Service’s 340B drug pricing discount program by 
including additional types of covered entities. The 340B 
pricing program requires participating manufacturers to 
agree to charge statutorily-defined covered entities no 
more 
the 
manufacturer’s  covered  outpatient  drugs.  PPACA 
expanded the 340B program to include additional types 
of covered entities as described above.  PPACA exempts 
“orphan  drugs”  designated  under  section  526  of  the 

the  340B  “ceiling  price” 

than 

for 

FDCA,  such  as  our  products,  from  the  ceiling  pricing 
requirements for these newly-eligible covered entities.

Moreover,  certain  legislative  changes  to  and 
regulatory changes under PPACA have occurred under 
the Trump Administration. For example, the Tax Cuts and 
Jobs  Act  enacted  in  2017  eliminated  the  shared 
responsibility  payment  for  individuals  who  fail  to 
maintain  minimum  essential  coverage  under  section 
5000A of the Internal Revenue Code, commonly referred 
to as the “individual mandate,” beginning in 2019. In 
December 2018, a federal district court in Texas ruled 
the individual mandate was unconstitutional and could 
not be severed from the PPACA. As a result, the court 
ruled the remaining provisions of the PPACA were also 
invalid, though the court declined to issue a preliminary 
injunction with respect to the PPACA. However, it remains 
unclear  whether  the  court’s  ruling  will  be  upheld  by 
appellate courts. In addition, further legislative changes 
to and regulatory changes under PPACA remain possible. 

Privacy, Data Protection and Information Security

Numerous  international,  federal,  and  state  laws, 
including  state  security  breach  notification  and 
information security laws, state privacy laws, and federal 
and  state  consumer  protection  laws  govern  the 
collection, use, and disclosure of personal information. 
In  addition,  most  healthcare  providers  who  prescribe 
and  dispense  our  products  and  research  institutions 
with  whom  we  collaborate  for  our  sponsored  clinical 
trials are subject to privacy and security requirements 
under  HIPAA,  as  amended  by  the  Health  Information 
Technology  for  Economic  and  Clinical  Health  Act 
(HITECH), and its implementing regulations. Although we 
are not directly subject to HIPAA other than with respect 
to  providing  certain  employee  benefits,  we  could  be 
potentially  subject  to  criminal  penalties  if  we,  our 
affiliates,  or  our  agents  knowingly  obtain  or  disclose 
individually  identifiable  health  information  maintained 
by  a  HIPAA  covered  entity  in  a  manner  that  is  not 
authorized  or  permitted  by  HIPAA.  In  addition,  in 
December 2018, HHS issued cybersecurity guidance for 
all 
addresses 
organizations 
organizations’  enterprise-level 
information  security 
generally,  including  individually  identifiable  health 
information. Failure to comply with current and future 
laws  and  regulations  could  result  in  governmental 
enforcement  actions  (including  the  imposition  of 
significant penalties), criminal and civil liability for our  
Company and our officers and directors, and/or adverse 
publicity that negatively affects our business. Further, 
the EU’s General Data Protection Regulation (GDPR) and 
implementing laws in the EU member states govern the 
collection and processing of EU residents’ personal data 
and,  among  other  requirements,  imposes  certain 
consent and data access rights. Such laws may impact 
our  ability  to  conduct  clinical  trials  that  involve  EU 
personal data and engage in other activities that require 
the processing of EU personal data. Outside of the U.S. 

healthcare 

that 

24

and the EU, there are numerous other jurisdictions that 
have  their  own  privacy  and  information  security  laws, 
and new laws and regulations are being considered and/
or enacted globally, which may affect our ability to collect, 
process, and store their residents’ personal data. Two 
such examples are the California Consumer Privacy Act 
of 2018 and the Brazilian Data Protection Law, which 
both go into effect in early 2020, and may impact our 
collection  and  use  of  personal  information  related  to 
their jurisdictions.

Moreover, we rely on our and third-party provided 
information  technology  systems  and  applications  to 
support  our  operations  and  to  maintain  and  process 
company  information  including  personal  information, 
confidential  business  information  and  proprietary 
information.  If  these  information  technology  systems 
are subject to cybersecurity attacks, or are otherwise 
compromised,  due  to  cyberattacks,  human  error  or 
malfeasance,  system  errors  or  otherwise,  it  may 
adversely impact our business, disrupt our operations, 
or  lead  to  the  loss,  theft,  destruction,  corruption  or 
compromise  of  company  information  and  personal 
information.  Such  information  technology  or  security 
events  could  also  lead  to  legal  liability,  regulatory 
investigations  or  actions,  loss  of  business,  negative 
media  coverage,  and  reputational  damage.  While  we 
maintain an information security program with technical 
controls to mitigate these risks and training to educate 
and  prepare  our  employees,  the  healthcare  sector 
continues to see a high frequency of cyberattacks and 
threat  actors 
to  become  more 
sophisticated  and  better  resourced,  and  our  systems 
and the information maintained within those systems 
remain potentially vulnerable to data security incidents. 
Moreover,  losses  from  such  events  may  not  be 
completely covered by insurance coverage.  Finally, as 
cyber  threats  continue  to  evolve  and  privacy  and 
cybersecurity laws and regulations continue to develop, 
we may need to invest additional resources to implement 
new compliance measures, strengthen our information 
security  posture,  or  respond  to  cyber  threats  and 
incidents.

that  continue 

Other Regulations

We  are  also  subject  to  the  U.S.  Foreign  Corrupt 
Practices Act (FCPA), the U.K. Bribery Act (U.K. Bribery 
Act),  and  other  anti-corruption  laws  and  regulations 
pertaining to our financial relationships and interactions 
with  foreign  government  officials.  The  FCPA  prohibits 
U.S.  companies  and  their  employees,  officers,  and 
representatives from paying, offering to pay, promising, 
or authorizing the payment of anything of value to any 
foreign government official, government staff member, 
political party, or political candidate to obtain or retain 
business or to otherwise seek favorable treatment. In 
many countries in which we operate or sell our products, 
the healthcare professionals with whom we interact may 
be  deemed  to  be  foreign  government  officials  for 

25

purposes  of  the  FCPA.  The  U.K.  Bribery  Act,  which 
applies to any company incorporated or doing business 
in the UK, prohibits giving, offering, or promising bribes 
in the public and private sectors, bribing a foreign public 
official or private person, and failing to have adequate 
procedures to prevent bribery amongst employees and 
other  agents.  Penalties  under  the  U.K.  Bribery  Act 
include  potentially  unlimited  fines  for  companies  and 
criminal sanctions for corporate officers under certain 
circumstances. Liability in relation to breaches of the 
U.K.  Bribery  Act  is  strict.  This  means  that  it  is  not 
necessary to demonstrate elements of a corrupt state 
of mind. However, a defense of having in place adequate 
procedures designed to prevent bribery is available.

Recent years have seen a substantial increase in 
anti-bribery law enforcement activity by U.S. regulators, 
with more frequent and aggressive investigations and 
enforcement proceedings by both the DOJ and the SEC, 
increased enforcement activity by non-U.S. regulators, 
and increases in criminal and civil proceedings brought 
against  companies  and  individuals.  In  May  2015,  we 
received a subpoena in connection with an investigation 
by  the  Enforcement  Division  of  the  SEC  requesting 
information  related  to  our  grant-making  activities  and 
compliance  with  the  FCPA  in  various  countries.  In 
addition, in October 2015, Alexion received a request 
from the DOJ for the voluntary production of documents 
and other information pertaining to Alexion’s compliance 
with  the  FCPA.  For 
information  concerning  this 
investigation  see  Note  11  “Commitments  and 
Contingencies” to the consolidated financial statements 
included elsewhere in this Annual Report on Form 10-K 
and, with respect to the the risks associated with the 
investigation,  see  our  Risk  Factors,  including    "Our 
business  and  operations  may  be  materially  adversely 
affected by government investigations." 

The  EU  also  imposes  strict  restrictions  on  the 
promotion  and  marketing  of  drug  products  in  the  EU, 
where  a  large  portion  of  our  non-U.S.  business  is 
conducted, and other territories.  Increasing regulatory 
scrutiny of the promotional activities of pharmaceutical 
companies also has been observed in a number of EU 
Member  States.  Laws  in  the  EU,  including  in  the 
individual  EU  Member  States,  require  promotional 
materials and advertising for drug products to comply 
with the product’s Summary of Product Characteristics 
(SmPC), which is approved by the competent authorities. 
Promotion of a medicinal product which does not comply 
with  the  SmPC  is  considered  to  constitute  off-label 
promotion.  The  off-label  promotion  of  medicinal 
products is prohibited in the EU and in other territories. 
The promotion of medicinal products that are not subject 
to  a  marketing  authorization  is  also  considered  to 
constitute off-label promotion and is prohibited in the 
EU. Laws in the EU, including in the individual EU Member 
States, also prohibit the direct-to-consumer advertising 
of prescription-only medicinal products. Violations of the 
rules governing the promotion of medicinal products in 

the  EU  and  in  other  territories  could  be  penalized  by 
administrative measures, fines and imprisonment.

Under the new Clinical Trial Regulation there is an 
obligation  to  publish  clinical  trial  within  a  certain 
timeframe. A breach of this obligation would constitute 
non-compliance with an EU Regulation and may be met 
with penalties set by each Member State, including civil 
and criminal liability.

Japan and other countries in which we operate also 
have strict regulations and requirements regarding the 
promotion of pharmaceutical products.

Interactions  between  pharmaceutical  companies 
and  physicians  are  also  governed  by  strict  laws, 
regulations,  industry  self-regulation  codes  of  conduct 
and  physicians’  codes  of  professional  conduct  in  the 
individual  EU  Member  States.  The  provision  of  any 
inducements  to  physicians  to  prescribe,  recommend, 
endorse, order, purchase, supply, use or administer a 
medicinal product is prohibited. A number of EU Member 
States  have  introduced  additional  rules  requiring 
pharmaceutical  companies  to  publicly  disclose  their 
interactions with physicians and to obtain approval from 
and/or 
employers, 
competent authorities before entering into agreements 
with physicians. These rules have been supplemented 
by  provisions  of  related  industry  codes,  including  the 
EFPIA  Disclosure  Code  on  Disclosure  of  Transfers  of 
Value  from  Pharmaceutical  Companies  to  Healthcare 
Professionals and Healthcare Organizations and related 
codes  developed  at  national  level  in  individual  EU 
Member States. Additional countries may consider or 
implement  similar  laws  and  regulations.  Violations  of 
these  rules  could  lead  to  reputational  risk,  public 
reprimands,  and/or 
fines  or 
imprisonment.

Competition 

ULTOMIRIS  and  SOLIRIS  are  currently  the  only 
approved therapies for the treatment of PNH (although 
several  companies  are  currently  evaluating  other 
complement  inhibitors  for  the  treatment  of  PNH  in 
clinical trials).  SOLIRIS is currently the only approved 
therapy for the treatment of aHUS, and the only approved 
complement inhibitor therapy for the treatment of AChR 
antibody-positive gMG (although similar to PNH, there 
are companies evaluating other complement inhibitors 
in both aHUS and gMG clinical trials).  We have recently 
announced the results of our SOLIRIS Phase III PREVENT 
trial  in  patients  with  anti-aquaporin-4  (AQP4)  auto 
antibody-positive NMOSD. Based on these results, we 
submitted applications for marketing authorization for 
SOLIRIS as a treatment for NMOSD in the US and the 
E.U.  and  expect  additional  marketing  authorization 
applications to be submitted in other jurisdictions in the 
future.  While we are unable to assess our competitive 
position with respect to potential NMOSD competitors, 
as we have not yet received regulatory approval in any 
jurisdiction,  we  are  aware  that  others  companies  are 
also developing and testing therapies for NMOSD. We 
are also in advanced clinical studies of ULTOMIRIS and 
SOLIRIS for the treatment of other indications, and we 
believe there are  competitors for the patient segments 
we target with respect to these products.  STRENSIQ is 
currently the only product approved for the treatment of 
HPP and KANUMA is the only product approved for the 
treatment of LAL-D. Many pharmaceutical and biotech 
companies  have  publicly  announced  intention  to 
establish or develop rare disease programs that may be 
competitive with ours. We also experience competition 
in  drug  development  from  universities  and  other 
research  institutions,  and  pharmaceutical  companies 
compete with us to attract universities and academic 
research  institutions  as  drug  development  partners, 
including  for  licensing  their  proprietary  technology. 
Some of these entities may have:

•  greater financial and other resources;

•  larger research and development staffs;

•  lower labor costs; and/or

• more  extensive  marketing  and  manufacturing 
organizations.

Many of these companies and organizations have 
significant  experience  in  preclinical  testing,  human 
clinical trials, product manufacturing, marketing, sales 
and  distribution  and  other  regulatory  approval  and 
commercial procedures. They may also have a greater 
number  of  significant  patents  and  greater  legal 
resources  to  seek  remedies  for  cases  of  alleged 
infringement  of  their  patents  by  us  to  block,  delay  or 
compromise our own drug development process.

We compete with large pharmaceutical companies 
that produce and market synthetic compounds and with 
specialized  biotechnology  firms  in  the  United  States, 

26

Europe and in other countries and regions, as well as a 
growing number of large pharmaceutical companies that 
are  developing  biotechnology  products.  A  number  of 
biotechnology  and  pharmaceutical  companies  are 
developing new products for the treatment of the same 
diseases being targeted by us. Other companies have 
initiated clinical studies for the treatment of PNH, aHUS, 
MG and NMOSD, and we are aware of companies that 
are planning to initiate studies for diseases we are also 
targeting. In addition, we are aware that companies are 
conducting clinical trials for biosimilars of SOLIRIS and 
we expect to compete with biosimilars in the future.

Several  biotechnology  and  pharmaceutical 
companies  have  programs  to  develop  complement 
inhibitor  therapies  or  have  publicly  announced  their 
the

indications by regulators in many jurisdictions around 
the world.

Risk Factors.

You  should  carefully  consider  the  following  risk 
factors before you decide to invest in Alexion securities 
and our business, because the risks described below may 
have a material impact on our business, operating results, 
financial  condition,  and  cash  flows.  The  risks  and 
uncertainties described below are not the only ones we 
face.  Additional  risks  and  uncertainties  not  presently 
known to us or that we currently deem immaterial may 
also impair our business operations. If any of the following 
risks actually occurs, our business, financial condition and 
results of operations could be materially and adversely 
affected.

Risks Related to Our Products and Product Candidates

We depend on the success of, and revenue from, 
Soliris. 

Since 2007, our revenue has depended primarily 
on the sales of Soliris.  Unless we are able to develop 
or acquire new products and technologies, successfully 
commercialize ULTOMIRIS as described in the following  
risk factor, and/or materially increase sales of Strensiq 
and  Kanuma  (two  of  our  other  currently  approved 
products), we will remain dependent on sales of Soliris 
as a source of our revenue.  

The commercial success of SOLIRIS and our ability 
to  generate  revenue  depends  on  several  factors, 
including: the safety and efficacy of SOLIRIS; coverage 
or reimbursement by government or third-party payers 
for SOLIRIS; pricing for SOLIRIS; the analysis by doctors 
and  patients  of  the  cost  of  SOLIRIS  relative  to  the 
perceived  benefits;  manufacturing  and  uninterrupted 
supply; the introduction of and success of competing 
products by competitors (including novel products and 
biosimilars to SOLIRIS); the size of patient populations 
and  the  number  of  patients  diagnosed  who  may  be 
treated with SOLIRIS; the impact of legal, administrative, 
regulatory or legislative developments; and our ability 
to  develop,  obtain 
for  and 
commercialize SOLIRIS for new indications.

regulatory  approval 

While  SOLIRIS  has  been  studied  for  indications 
beyond  PNH,  aHUS  and  gMG  (which  are  the  current 
approved indications of SOLIRIS), there is no guarantee 
that we can obtain regulatory approval or achieve any 
commercial  sales  of  SOLIRIS  for  other  indications.  
Despite  positive  topline  results  from  the  Phase  3 
PREVENT  study  of  SOLIRIS  in  patients  with  anti-
aquaporin-4 (AQP4) auto antibody-positive neuromyelitis 
optica spectrum disorder (NMOSD), we may not be able 
to  obtain  regulatory  approval  to  sell  SOLIRIS  as  a 
treatment  for  NMOSD  due  to  the  failure  to  meet 
applicable regulatory requirements. Additionally, even if 
we obtain regulatory approval, physicians and patients 

30

may not accept SOLIRIS as a treatment for NMOSD or 
payers may not be willing to pay for or reimburse the 
costs of SOLIRIS as a therapy for NMOSD.

If we are not able to maintain revenues from sales 
of  SOLIRIS,  or  our  SOLIRIS  revenues  decrease,  our 
operating results would be negatively impacted and our 
ability to fund research and development programs for 
the  discovery  and  commercialization  or  acquisition  of 
new products would be harmed, which would limit our 
ability to diversify our revenue base and our stock price 
could be adversely affected.

If PNH patients do not switch from SOLIRIS to ULTOMIRIS 
or  ULTOMIRIS  does  not  gain  market  acceptance,  our 
future operating results may be adversely impacted.

In December 2018, ULTOMIRIS was approved by 
the FDA for use in the U.S. for adult patients with PNH 
(and applications for approval of ULTOMIRIS are under 
review by the European Medicines Agency (EMA) and the 
Ministry of Health, Labour and Welfare (MHLW) in Japan 
for patients with PNH).

One  of  our  principal  business  objectives  is  to 
facilitate the conversion of PNH patients from SOLIRIS 
to  ULTOMIRIS.  While  clinical  trials  demonstrated  that 
ULTOMIRIS is non-inferior to SOLIRIS at an 8 week dosing 
interval  (compared  to  a  2  week  dosing  interval  for 
SOLIRIS), existing PNH patients taking SOLIRIS and their 
physicians may decline to switch to ULTOMIRIS for many 
reasons including: reluctance to try a new therapy, lack 
of  clinical  evidence  that  ULTOMIRIS  is  superior  to 
SOLIRIS, no (or limited) reimbursement by government 
or third-party payers (including as a result of SOLIRIS 
being available as an alternative therapy), or our inability 
to manufacture quantities necessary to meet demands. 

If we achieve our goal of promptly facilitating the 
conversion  of  current  PNH  patients  from  SOLIRIS  to 
ULTOMIRIS, we anticipate that revenue from SOLIRIS, 
which accounted for approximately $3,563.0, or 86.3%, 
of our revenues in 2018, will decline as we move patients 
to  ULTOMIRIS.   We  have  established  a  price  for 
ULTOMIRIS  in  the  U.S.  that,  on  an  annual  basis, 
represents an approximate 10% discount to the cost of 
current  labeled  maintenance  therapy  for  SOLIRIS  for 
adult  PNH  patients  of  average  weight.  However,  this 
represents an approximate 10% premium to the cost of 
SOLIRIS in a patient’s first year of switching due to the 
loading doses required.

We may not obtain marketing approval for ULTOMIRIS 
as a treatment for PNH in any jurisdictions beyond the 
U.S. or for any indications beyond PNH. 

There is no guarantee that the EMA or the MHLW 
(or any other regulatory authority) will promptly approve 
the use of ULTOMIRIS in PNH patients or that they will 
approve the use of ULTOMIRIS in PNH patients at all. 
We  believe  that  the  EU  and  Japan  may  be  important 

potential markets for ULTOMIRIS and if we are not able 
to sell ULTOMIRIS in these geographies, our business 
may be adversely impacted.

Subject to successful completion of clinical trials, 
we intend to pursue marketing approval for ULTOMIRIS 
in  the  U.S.,  the  EU,  Japan  and  other  jurisdictions  for 
indications  in  addition  to  PNH  and,  potentially,  other 
delivery mechanisms. The FDA, the EMA or the MHLW 
could reject our applications for indications beyond PNH 
(and the EMA and the MHLW could reject our application 
for ULTOMIRIS for PNH) or for a subcutaneous delivery 
mechanism for many reasons, including due to a finding 
of  inadequate  safety,  tolerability,  potency  or  efficacy 
profiles.  Additionally,  these  and  other  regulatory 
agencies may request that we provide additional safety 
or efficacy data, which may require significant additional 
time  and  expense  to  generate  prior  to  a  decision  on 
approval.

If  ULTOMIRIS  is  not  approved  for  use  in  PNH 
patients in the EU or Japan (or other jurisdictions) or for 
any other indications or for subcutaneous administration 
in the U.S., the EU, Japan or elsewhere or if any such 
approval is delayed, our future business and results of 
operations may be harmed. In the event of any of the 
foregoing, while we would continue to sell SOLIRIS in 
the jurisdictions and for the indications authorized by 
the appropriate authorities, certain of the patents and 
regulatory exclusivities related to SOLIRIS expire earlier 
than  patents  and  regulatory  exclusivities  we  hold  on 
ULTOMIRIS, which may allow competitors to enter those 
markets at an earlier date utilizing SOLIRIS or biosimilar 
technology.

Our  future  commercial  success  depends  on  gaining 
regulatory  approval  for  new  products  and  obtaining 
approvals for existing products for new indications.

We  have  invested,  and  continue  to  invest, 
significant  amounts  in  acquiring  new  products  and 
technologies  and  advancing  our  existing  product 
candidates  and  technologies.  Our  long-term  success 
and  revenue  growth  will  depend  upon  the  successful 
identification, acquisition (including licenses from third 
parties),  development  and  commercialization  of  new 
products and technologies, and approval of additional 
indications for our existing products and products under 
development. Product development (including products 
acquired  in  connection  with  acquisitions)  is  very 
expensive,  takes  significant  time  to  obtain  regulatory 
approval and involves a high degree of risk. Only a small 
number of research and development programs result 
in the commercialization of a product. The process for 
obtaining  regulatory  approval  to  market  a  biologic  is 
expensive,  often  takes  many  years,  and  can  vary 
substantially based on the type, complexity, the novelty 
of the product candidates involved and the indications 
to  be  treated.  Further,  success  in  early  clinical  trials, 
which  may  lead  to  further  investment  in  a  product 
candidate by us, may not result in success in later stage 

trials. In addition, our recent acquisitions have focused 
on  new  technologies  with  which  we  have  very  limited 
experience,  including  antibody  therapeutics  targeting 
the  neonatal  Fc  receptor,  which  may  make  the 
development, approval and commercialization of such 
potential products challenging.

Our  ability  to  maintain  or  grow  revenues  may  be 
adversely  affected  if  we  are  delayed  or  unable  to 
successfully develop the products in our pipeline, if we 
are unable to gain approval for SOLIRIS and ULTOMIRIS 
for additional indications and in new jurisdictions, obtain 
marketing  approval  for  STRENSIQ  and  KANUMA  in 
additional  territories,  obtain  approval  for  additional 
delivery  systems 
(such  as 
subcutaneous  administration)  or  acquire  or  license 
products and technologies from third parties.

therapies 

for  our 

If  we  do  not  obtain  regulatory  approval  of  new 
products or additional indications for existing products 
or  additional  delivery  systems,  or  are  significantly 
delayed  or  limited  in  doing  so,  our  revenue  may  be 
adversely affected, we may experience surplus inventory, 
we may be required to write down certain assets, our 
business may be materially harmed and we may need 
to significantly curtail operations. 

We  develop  therapies  for  rare  diseases  with  limited 
patient  populations  that  have  not  been  definitively 
determined, and our success will depend on our ability 
to identify patients in the disease areas we target.

The therapies that we have developed and that are 
in  our  product  pipeline  target  diseases  that  have  a 
limited number of patients and for which, in many cases, 
there  are  either  no  or  limited  diagnostics  tools.  For 
example,  KANUMA  and  STRENSIQ  are  currently 
approved to treat ultra-rare diseases with small patient 
populations that have not been definitively determined. 
Our  development  pipeline  programs  that  may  be  the 
basis for future revenue growth also focus on rare (and 
ultra-rare) diseases for which there are a very limited 
number of patients. The lack of diagnostic tools, coupled 
with the fact that there is frequently limited awareness 
among certain health care providers concerning the rare 
diseases we treat, often means that a proper diagnosis 
can, and frequently does, take years to identify (or an 
appropriate  diagnosis  may  never  be  made  for  certain 
patients). As a result, we may not be able to grow our 
revenues  (even  as  we  introduce  new  products  or  as 
existing  products  are  approved 
for  additional 
indications). There can be no guarantee that any of our 
programs  will  be  effective  at  identifying  patients,  and 
even if we can identify patients that our therapies can 
help, the number of patients that our therapies treat may 
turn out to be lower than we expect, may not be otherwise 
amenable  to  treatment  with  our  products  (such  as 
KANUMA and STRENSIQ), or new patients may become 
increasingly  difficult  to  identify,  all  of  which  may 
adversely  affect  our  results  of  operations  and  our 
business. In addition, even in instances where we do 

31

add patients, the number may be less than the number 
of  patients  that  discontinue  use  of  the  applicable 
product  in  a  given  period  resulting  in  a  net  loss  of 
patients and potentially decreased revenue. 

We  may  not  be  able  to  gain  or  maintain  market 
acceptance  of  our  products  among  the  medical 
community, patients or payers, which could prevent us 
from maintaining profitability or growth.

Our  products  may  not  gain  or  maintain  market 
acceptance  among  physicians,  patients,  healthcare 
payers and others. Although we have received regulatory 
approval for certain of our products in certain territories, 
such  approvals  do  not  guarantee  future  revenue.  We 
cannot  predict  whether  physicians,  other  healthcare 
providers, government agencies or private insurers will 
determine or continue to accept that our products are 
safe and therapeutically effective and that the benefits 
are meaningful relative to the cost. Nor can we predict 
whether patients, physicians or payers will continue use 
of SOLIRIS or elect to convert to ULTOMIRIS in the U.S. 
(or other jurisdictions if and when approved for use by 
the  appropriate  regulatory  authorities)  or  alternative 
treatments  that  may  become  available.  Physicians’ 
willingness  to  prescribe,  and  patients’  willingness  to 
accept,  our  products,  depends  on  many  factors, 
including:

• prevalence and severity of adverse side effects in 

both clinical trials and commercial use;

• the timing of the market introduction of competitive 

drugs and biosimilars;

• demonstrated  clinical  safety  and  efficacy 

compared to other drugs;

• perceived cost-effectiveness and/or evaluations in 

HTAs;

• pricing and availability of reimbursement from third-
party payers, including governmental entities;

•  convenience and ease of administration;

• effectiveness of our marketing strategy;

• publicity  concerning  our  products  and  our  other 
product  candidates  (and  those  of  competitive 
products); and

• availability of alternative treatments.

The likelihood of physicians to prescribe SOLIRIS 
for patients with aHUS (and ULTOMIRIS, if approved for 
use by aHUS patients) may also depend on how quickly 
SOLIRIS can be delivered to the hospital or clinic and 
our distribution methods may not be sufficient to satisfy 
this  need.  In  addition,  we  are  aware  that  some 
healthcare providers have determined not to continue 
SOLIRIS treatment for some patients with aHUS. While 
SOLIRIS as a treatment for aHUS is recommended by 
some regulatory authorities to be used for the duration 
of a patient’s lifetime, we are aware that some healthcare 
providers prescribe SOLIRIS for aHUS for a shorter time 

32

period and, in some cases, may prescribe SOLIRIS for 
aHUS in emergency or acute situations only. Decisions 
such as this by aHUS patients and healthcare providers 
to use our products for a period that is less than the 
remaining  lifetime  of  the  patient  or  in  only  acute 
circumstances  can  cause  our  SOLIRIS  revenues,  and 
revenues for our other products, to fluctuate and past 
sales  of  our  products  may  not  be  indicative  of  future 
sales for such products.

If our products fail to achieve or maintain market 
acceptance among the medical community or patients 
in a particular country, we may not be able to market 
and sell our products successfully in such country, which 
may limit our ability to generate revenue and could harm 
our overall business.

If our products harm patients, or are perceived to harm 
patients  even  when  such  harm  is  unrelated  to  our 
products, our regulatory approvals could be revoked or 
otherwise negatively impacted and we could be subject 
to costly and damaging product liability claims.

The testing, manufacturing, marketing and sale of 
biologics for use in humans may cause harm to patients, 
which exposes us to product liability risks and regulatory 
penalties. 

Our  products  and  our  product  candidates  treat 
patients with rare diseases and, as a result, we generally 
are able to test our products in only a small number of 
patients. As more patients use our products, including 
more  children  and  adolescents,  new  risks  and  side 
effects may be discovered, the rate of known risks or 
side effects may increase, and risks previously viewed 
as less significant could be determined to be significant. 
Previously unknown risks and adverse effects may also 
be discovered in connection with unapproved uses of 
our products, which may include administration of our 
products  under  acute  emergency  conditions,  such  as 
the Enterohemorrhagic E. coli health crisis in Europe, 
primarily  Germany,  which  began  in  May  2011.  Under 
pharmacovigilance guidelines, we are required to timely 
report any adverse events any patient using our products 
experiences and any clinical evaluations of outcomes in 
the post-marketing setting are required to be reported 
to appropriate regulatory agencies in accordance with 
relevant regulations, as a result any potential adverse 
events  will  be  promptly  brought  to  the  attention  of 
regulators that may likely require prompt remedial action 
(and any failure to report these adverse events or report 
such events in a timely manner may result in penalties 
being imposed by regulators). In the event any new risks 
or  adverse  effects  discovered  as  new  patients  are 
treated for approved indications, or as our products are 
studied  in  or  used  by  patients  for  other  indications, 
regulatory  authorities  may  delay  or  revoke  their 
approvals,  we  may  be  required  to  conduct  additional 
clinical  trials  and  safety  studies,  make  changes  in 
labeling, reformulate our products or make changes and 
obtain  new  approvals  for  our  and  our  suppliers’ 

manufacturing  facilities.  If  we  experience  any  of  the 
foregoing  actions,  it  may  harm  our  reputation  and, 
particularly given that we rely on a very limited number 
of products for our revenue, our business and results of 
operations could be materially and adversely impacted. 
Further,  any  investigation  into  the  circumstances 
surrounding an adverse event may be costly and time 
consuming (even if it is ultimately determined that the 
adverse event is not the result of the use of our product) 
or the investigation may not be sufficiently conclusive 
to prevent a regulatory authority from taking one of the 
foregoing actions against us. 

a 

experiencing 

In addition, many patients who use our products 
are  already  very  ill  and  may  suffer  adverse  events, 
including death, during treatment for reasons that may 
or may not be related to our products. Also, there are 
risks associated with our products; for example, use of 
C5  Inhibitors,  such  as  SOLIRIS  and  ULTOMIRIS,  is 
associated with an increased risk for certain types of 
infection, including meningococcal infection. In certain 
cases, a physician may not have the opportunity to timely 
vaccinate a patient in the event of an acute emergency 
episode,  such  as  in  a  patient  presenting  with  aHUS, 
which  could  result  in  the  patient  using  SOLIRIS  or 
ULTOMIRIS 
life-threatening 
meningococcal infection (and even in certain cases in 
which a vaccination can be delivered to the patient, it 
may not, eliminate all risk of meningococcal infection). 
Patients  using  our  products  and  product  candidates 
have  died  or  suffered  potentially 
life-threatening 
conditions either during or after ending their treatments, 
and  these  include  patients  who  have  died  while 
participating in a clinical trial (for example, four patients 
died  during  the  ULTOMIRIS  Phase  III  clinical  trial  for 
aHUS, although none of these were considered related 
to the treatment with ULTOMIRIS). We may be sued by 
patients who are harmed during the course of using our 
products,  whether  as  a  prescribed  therapy,  during  a 
clinical  trial,  during  an  investigator  initiated  study,  or 
otherwise.  Any  such  product  liability  lawsuit  or  injury 
claim, which could include class actions, could harm our 
reputation  among  patients,  physicians,  payers  and 
others  and  require  us  to  pay  substantial  amounts  of 
money  to  injured  patients,  and  even  if  successfully 
defended, could have a material adverse effect on our 
business,  financial  condition  or  results  of  operations 
due to the expense of defending any such claim. While 
we do have product liability insurance, it may not cover 
all potential types of liabilities or may not cover certain 
liabilities completely. Moreover, we may not be able to 
maintain our insurance on acceptable terms, or at all. 

We anticipate that we may face increased competition 
from  companies  that  will  enter  into  the  markets  we 
currently serve and as our product pipeline expands into 
markets that are currently served by other companies.

We expect that the business environment in which 
we  operate  will  become  increasingly  competitive. 

33

Currently, certain of our products are the only approved 
therapy  for  the  indication  they  treat.  For  example, 
SOLIRIS  and  ULTOMIRIS  (in  the  U.S.)  are  the  only 
approved treatments of PNH. In the future, we expect 
that  SOLIRIS  and  ULTOMIRIS  may  compete  with  new, 
novel  drugs  and  pharmaceuticals  currently 
in 
development.  For  example,  several  companies  are 
developing and engaged in clinical trials for therapies to 
treat PNH, aHUS, and gMG. If SOLIRIS is approved for 
treatment  of  NMOSD,  we  expect  there  may  be 
competition  in  that  market  as  well.  Since  other 
companies  are  also  operating  clinical  trials  in  this 
disease  state.  Additionally,  other  pharmaceutical 
companies have publicly stated that they are developing 
and intend to commercialize a SOLIRIS biosimilar and 
these biosimilars may be commercially available in the 
future.  STRENSIQ  and  KANUMA  may  also  experience 
competition  in  the  future.  We  are  also  aware  of 
companies  that  are  planning  to  initiate  studies  for 
diseases  that  we  are  also  targeting  with  our  product 
pipeline. Our revenues could be negatively affected if 
patients or potential patients enroll in our clinical trials 
or  clinical  trials  of  other  companies  with  respect  to 
diseases that we also target with approved therapies.

Other  pharmaceutical  companies  have  publicly 
announced  intentions  to  establish  or  develop  rare 
disease  programs  and  may  introduce  products  that 
compete with ours (or products that are in our pipeline). 
These  and  other  companies,  many  of  which  have 
significantly greater financial, technical and marketing 
resources than us, may commercialize products that are 
cheaper, more effective, safer, have less frequent dosing 
schedules, or easier to administer than our products. 
Our  current  and  future  competitors  may  develop 
products that are more broadly accepted or may receive 
patent protection that dominates, blocks or adversely 
affects  our  product  development  or  business.  These 
competitive  products, 
including  any  biosimilars 
approved  under  alternative  regulatory  pathways,  may 
significantly reduce both the price that we receive for 
such marketed products and the volume of products that 
we sell, which may negatively impact our revenues and 
profitability. Given that a significant portion of our 2018 
revenue  was  attributable  to  SOLIRIS,  one  or  more 
competitive  products  or  biosimilar  could  have  a 
significant impact on our entire business. In addition, 
we  experience  competition  in  drug  development  from 
universities  and  other  research  institutions,  and 
pharmaceutical companies compete with us to attract 
universities and academic research institutions as drug 
development  partners,  including  for  licensing  their 
proprietary technology. If our competitors successfully 
into  such  arrangements  with  academic 
enter 
institutions, we may be precluded from pursuing those 
unique  opportunities  and  may  not  be  able  to  find 
equivalent opportunities elsewhere. 

If  a  company  announces  successful  clinical  trial 
results for a product that may be competitive with one 

of  our  products  or  product  candidates,  receives 
marketing approval of a competitive product, or gets to 
the market before we do with a competitive product, our 
business may be harmed or our stock price may decline.

Risks Related to Pricing and Reimbursement

Sales  of  our  products  depend  on  reimbursement  by 
government authorities, private health insurers and other 
organizations, each of which are subject to pressures to 
contain costs. If we are unable to obtain, or maintain at 
anticipated levels, reimbursement for and access to our 
products,  or  coverage  is  reduced,  our  pricing  may  be 
adversely  affected  or  our  product  sales,  results  of 
operations or financial condition could be harmed.

Our products are significantly more expensive than 
traditional  drug  treatments  and  almost  all  patients 
require  governmental  payers,  such  as  Medicare  and 
Medicaid in the U.S. or country specific governmental 
organizations in foreign countries, and/or private third-
party payers to pay all or a portion of the cost of our 
products. There is also a significant trend in the health 
care industry by public and private payers to contain or 
reduce their costs. As a result, payers have in the past 
(i)  decreased  the  portion  of  costs  they  will  cover,  (ii) 
ceased providing adequate payment for our products or 
(iii) not covered our products at all, each of which payers 
may continue to do in the future (or other payers who 
have not taken such actions in the past may do so in 
the future). Any of the foregoing may have an adverse 
impact on our revenue and results of operations.

coverage, 

Our ability to set the price for our products varies 
significantly from country to country, including in those 
countries  where  pricing,  coverage,  reimbursement  or 
funding  of  prescription  drugs  are  subject 
to 
governmental  control.  We  may  be  unable  to  timely  or 
successfully 
and 
reimbursement on terms that are favorable to us (or at 
all), or such coverage, pricing and reimbursement may 
differ in separate regions in the same country. In some 
foreign countries, the proposed pricing for a drug must 
be approved before it may be lawfully marketed, which 
could delay market entry (or, if pricing is not approved, 
we may be unable to sell at all in a country where we 
have  received  regulatory  approval  for  a  product).  In 
addition,  authorities 
impose 
additional obligations, such as HTAs, which assess how 
well  a  pharmaceutical  works  in  relation  to  its  cost. 
Additionally,  U.S.  payers  are  increasingly  considering 
new metrics as the basis for reimbursement rates. If 
our  products  do  not  meet  or  surpass  these  metrics, 
including any HTAs and other metrics imposed on our 
products, these payers may not reimburse for use of our 
products or may reduce the rate of reimbursement for 
our products and as a result we expect revenue from 
such  product  may  decrease.    We  may  also,  in  some 

in  some  countries 

cases, elect to reduce prices or reimbursement with third 
parties which we believe provides value in the long term.

Further,  certain  countries  establish  pricing  and 
reimbursement amounts by reference to the price of the 
same or similar products in other countries. Therefore, 
if coverage or the level of reimbursement is limited in 
one or more countries, we may be unable to obtain or 
maintain anticipated pricing or reimbursement in other 
countries or in new markets. In Canada, for example, 
the  Patented  Medicine  Prices  Review  Board  (PMPRB) 
issued  a  decision  in  an  administrative  pricing  matter 
that  we  had  excessively  priced  SOLIRIS  in  a  manner 
inconsistent  with  the  Canadian  pricing  rules  and 
guidelines and ordered that the price be decreased to 
no  higher  than  the  lowest  price  in  seven  comparator 
countries (we filed an application for judicial review of 
the PMPRB’s decision in the Federal Court of Canada, 
and a hearing on the matter was held in November 2018, 
but  we  are  unable  to  determine  the  outcome  of  this 
review at this time since the court has not yet issued 
its  opinion).  In  addition,  the  current  U.S.  presidential 
administration recently unveiled a number of proposals, 
among these was a recommendation to move from the 
current U.S. pricing and reimbursement regime to one 
that would establish pharmaceutical pricing by reference 
to a target price derived from the international price index 
(such a change may be expected to result in significant 
savings  for  the  government  for  purchases  of  certain 
pharmaceuticals).  If  the  U.S.,  which  accounted  for  a 
significant portion of our revenue in 2018, were to move 
to a pricing system based on the international price index 
(or similar model) that were to apply to our products, we 
expect that our revenues for sales in the U.S. (or any 
other country adopting such a price index) may decrease, 
and such decrease may be material in amount.

Due  to  the  cost  of  our  therapies,  any  potential 
increase in the number of patients receiving our products 
(for example, we expect there may be increases in sales 
of  SOLIRIS  for  patients  with  NMOSD,  if  approved  by 
regulatory  authorities  for  that  indication),  may  cause 
third-party payers to modify, limit or eliminate coverage 
or reimbursement for our products because they may 
require  an  allocation  of  a  greater  percentage  of  the 
potential  financial  resources  of  any  public  or  private 
payer for our products.

Further,  health  insurance  programs  may  utilize 
coverage  incentives  and  obstacles  to  discourage 
beneficiaries from using higher priced products such as 
ours, including:

• establishing formularies under which only selected 

drugs are covered;

• utilizing variable co-payments that make drugs that 
are not preferred by the payer more expensive for 
patients; and 

34

• utilizing  management 

as 
requirements for prior authorization or failure first 
on another type of treatment.

controls, 

such 

Any of these actions may subject our products to 

payer-driven restrictions. 

In  countries  where  patients  have  access  to 
insurance, their insurance co-payment amounts or other 
benefit  limits  may  represent  a  barrier  to  obtaining  or 
continuing  use  of  our  products  or  adoption  of  new 
treatment  options,  such  as  ULTOMIRIS.  The 
continuation of the use of these types of limits or barriers 
by  insurers  or  the  imposition  of  similar  limitations  or 
barriers in the future may have an adverse impact on 
our revenue and results of operations. In some cases, 
we have financially supported non-profit organizations 
that assist patients in accessing treatment for PNH and 
aHUS, including SOLIRIS, among other therapies. Such 
organizations assist patients whose insurance coverage 
imposes  prohibitive  co-payment  amounts  or  other 
expensive  financial  obligations.  Such  organizations’ 
ability to provide assistance to patients is dependent 
on  funding  from  external  sources,  and  we  cannot 
guarantee that such funding will be provided at adequate 
levels,  if  at  all.  We  have  also  provided  our  products 
without charge to patients who have no insurance (or 
limited  insurance)  coverage  for  drugs  through  related 
charitable  purposes.  We  are  not  able  to  predict  the 
financial impact of the support we may provide for these 
and  other  charitable  purposes;  however,  substantial 
support  could  have  a  material  adverse  effect  on  our 
profitability in the future. As third-party payers attempt 
to contain health care costs they are demanding price 
discounts  or  rebates  and  limiting  both  the  types  and 
variety of drugs that they may cover and the amounts 
that they will pay for drugs. As a result, they may not 
cover or provide adequate payment to patients for our 
products or they may demand discounts or rebates from 
us, which may be material.

Our commercial success depends on obtaining and 
maintaining  pricing  for  our  products,  which  is  directly 
tied to reimbursement for our products at anticipated 
levels for our products. It is difficult to project the impact 
of evolving reimbursement mechanics on the willingness 
of  payers  to  cover  our  products,  but  we  expect 
pharmaceutical  pricing  to  continue  to  be  subject  to 
intense  payer,  political  and  societal  pressures  on  a 
global  basis.  If  we  are  unable  to  obtain  or  maintain 
coverage  for  our  products,  or  coverage  is  reduced  or 
eliminated in one or more countries or if the U.S. (or 
other countries) were to move to an international price 
index for our products, our pricing, product sales, results 
of operations or financial condition could be harmed.

Risks Related to Business Operations

We rely on a limited number of facilities to produce our 
products  and  manufacturing  issues  at  our  facilities  or 
the  facilities  of  our  third  party  service  providers  could 
cause 
delay 
shortages, 
commercialization of our products, disrupt or delay our 
clinical  trials  or  regulatory  approvals,  and  adversely 
affect our business.

product 

stop 

or 

The  majority  of  our  products  and  product 
candidates are biologics, which cannot be manufactured 
synthetically  and  must  be  produced  from  biologic 
sources.  As  a  result,  the  production  of  biologic 
therapeutics  that  meet  all  product  specification  and 
regulatory  requirements  is  particularly  complex.  Even 
slight deviations at any point in the production process 
may lead to production failures or recalls.  For example, 
in 2013 and 2014 we undertook a voluntary recall of 
SOLIRIS  due  to  the  presence  of  visible  particles  in  a 
limited  number  of  vials.  In  addition,  because  the 
production process involves the use of materials that 
are derived from biological sources, the process can be 
affected  by  contaminants  that  could  impact  those 
biological micro-organisms. Therefore, the manufacture 
of  our  products  and  our  product  candidates  is  highly 
regulated, complex and difficult, and, as noted above, 
even minor technical problems or deviations could result 
in significant defects or failures and regulatory action 
against us. These manufacturing challenges are coupled 
with  the 
limited  experience 
manufacturing  commercial  quantities  of  ULTOMIRIS, 
STRENSIQ  and  KANUMA  (so  we  may  have  limited 
previous experience resolving any issues in connection 
with the manufacture of these products and it may take 
significant time to remediate or we may be unable to 
solve  any  manufacturing  problems)  and  we  rely  on  a 
limited number of facilities to manufacture our products 
for  our  development,  clinical  and  commercialization 
needs, some of which we own and some of which are 
owned by third parties. 

fact  that  we  have 

If we and/or our third party suppliers fail to meet 
the highly technical requirements of manufacturing our 
biologic  products  and  our  strict  quality  and  control 
specifications,  we 
(or  they)  may  be  unable  to 
manufacture or supply our products. We depend on our 
third  party  manufacturers  to  perform  effectively  on  a 
timely basis and to comply with regulatory requirements 
and meet our product specifications. If they are unable 
to do so, our contractual rights to address any failures 
and right to recover damages are limited. Our failure or 
the failure of our third-party manufacturers to produce 
sufficient  quantities  of  our  products  and  product 
candidates  could  result  in  lost  revenue,  diminish  our 
profitability,  delay  the  development  of  our  product 
candidates,  delay  regulatory  approval,  result  in  the 
rejection of our product candidates or result in supply 
shortages for our patients, which may lead to lawsuits, 

35

loss  of  revenue  or  could  accelerate  introduction  of 
competing products to the market. 

As noted above, the manufacture of our products 
and product candidates is at high risk of product loss 
due to contamination, equipment malfunctions, human 
error  or  raw  material  shortages,  which  may  result  in 
reduced  production  yields,  product  defects  and  other 
If  microbial,  viral  or  other 
supply  disruptions. 
contaminations  are  discovered  in  our  products  or 
manufacturing facilities, or the facilities of our third party 
manufacturers, we or our third party manufacturers may 
need to close our or their manufacturing facilities for an 
extended period of time to investigate and remediate 
the contaminant.

If  we  underestimate  demand  for  ULTOMIRIS, 
SOLIRIS or any of our products, or experience product 
interruptions  at  Alexion’s 
internal  manufacturing 
facilities or a facility of a third party provider, including 
as a result of risks and uncertainties described in this 
Annual  Report  on  Form  10-K,  we  may  not  be  able  to 
increase  our  revenues  and  alternative  therapies  may 
gain greater market acceptance.

We also face external factors, many of which are 
beyond  our  control,  that  could  cause  production 
interruptions at our facilities or at the facilities of our 
third party providers, including natural disasters, labor 
disputes, acts of terrorism or war. 

The  risks  to  our  business  of  any  manufacturing 
stops or interruptions (whether the result of internal or 
external  factors)  are  amplified  because  we  rely  on  a 
limited number of facilities to produce our products and 
product candidates. For example, each of our products 
is manufactured at only one to two facilities. Sales of 
SOLIRIS, which accounted for 86.3% of our revenue for 
the fiscal year ended December 31, 2018, in the U.S., 
the  EU,  Japan  and  certain  other  territories  were 
manufactured  exclusively  by  Lonza  at  its  facilities  in 
Singapore  and  Spain.  Manufacturing  SOLIRIS  for 
commercial sale in certain other territories may only be 
performed at a single facility in some cases until such 
time  as  we  have  received  the  required  regulatory 
approval for an additional facility, if ever. We expect that 
we  will  continue  to  rely  on  a  very  limited  number  of 
manufacturing  facilities  in  the  future  for  all  of  our 
products, including ULTOMIRIS.

in  other 

We  and  our  third  party  providers  are  required  to 
maintain  compliance  with  cGMP  and  other  stringent 
operation  and  manufacturing  requirements  and  are 
subject  to  inspections  by  the  FDA  and  comparable 
agencies 
jurisdictions  to  confirm  such 
compliance. Governmental authorities will generally not 
permit products manufactured at a facility that is not 
registered by the applicable government agency to enter 
into the country and such products may be returned for 
failure  to  comply  with  such  regulation,  which  may 
decrease  or  delay  sales  and  result  in  the  loss  of 
inventory.  Any  delay,  interruption  or  other  issues  that 

36

arise in the manufacture, fill-finish, packaging or storage 
of our products as a result of a failure of our facilities 
or the facilities or operations of third parties to pass any 
regulatory  agency  inspection  or  comply  with  on-going 
operating  regulations  could  significantly  impair  our 
ability to supply our products and product candidates. 
Significant  noncompliance  could  also  result  in  the 
imposition of monetary penalties or other civil or criminal 
sanctions and damage our reputation. 

Our  efforts  to  bring  more  of  our  manufacturing 
operations  under  our  control  present  additional 
challenges.  We  have  completed  the  build-out  of  a  fill-
finish facility in Ireland to support global drug product 
manufacture or vial fill finish of SOLIRIS and certain of 
our  other  clinical  and  commercial  products.  We  also 
completed construction of a facility in Dublin, Ireland in 
the  fourth  quarter  of  2015,  which  is  comprised  of 
laboratories,  packaging  and  warehousing  operations 
and we intend to make significant further investment in 
this facility for the manufacture of our products.  We are 
also constructing new biologics manufacturing facilities 
at both sites. Despite the significant investment we have 
made  in  these  facilities  and  operations,  we  cannot 
guarantee that we will be able to successfully and timely 
complete the construction of the biologics facilities or 
the  appropriate  validation  processes  or  obtain  the 
necessary  regulatory  approvals  for  these  and  other 
facilities, or that we will be able to perform the intended 
manufacturing  and  supply  chain  services  at  these 
facilities  for  commercial  or  clinical  use.  Prior  to  such 
time, we may continue to rely on third parties for these 
services.

If we experience any manufacturing issues, we may 
be unable to timely identify alternative manufacturers, 
and  if  we  are  able  to  timely  identify  alternative 
manufacturers, such alternative manufactures may not 
be able to satisfy our requirements. No guarantee can 
be  made  that  regulators  will  approve  additional  third 
party providers in a timely manner or at all, or that any 
third party providers will be able to perform services for 
sufficient product volumes for any country or territory. 
Further, due to the nature of the current market for third-
party  commercial  manufacturing,  many  arrangements 
require substantial penalty payments by the customer 
for failure to use the manufacturing capacity for which 
it contracted. The payment of a substantial penalty could 
harm our financial condition and may restrict our ability 
to transition to internal manufacturing or manufacturing 
by  other  third  parties.  In  addition,  the  terms  and 
conditions 
third  party 
to  engage  an  additional 
manufacturer  may  not  be  as  favorable  to  us  as  our 
current arrangements and may likely reduce the profit 
on the sales of any products to which they relate. 

In addition, KANUMA is a transgenic product and 
the facilities on which we rely to produce raw material 
for KANUMA are the only animal facilities in the world 
that produce the necessary egg whites from transgenic 

chickens.  Natural  disasters,  disease,  such  as  exotic 
Newcastle  disease  or  avian 
influenza,  or  other 
catastrophic events could have a significant impact on 
the supply of unpurified KANUMA, or destroy our animal 
operations  altogether.  If  our  animal  operations  are 
disrupted, it may be extremely difficult to set up another 
animal facility to supply the unpurified KANUMA. 

Any  adverse  developments  affecting  our 
manufacturing operations or the operations of our third-
party  providers  could  result  in  a  product  shortage  of 
clinical or commercial requirements, withdrawal of our 
product candidates or any approved products, shipment 
delays, lot failures or recalls. We may also have to write-
off inventory and incur other charges and expenses for 
products  that  fail  to  meet  specifications,  undertake 
costly  remediation  efforts  or  seek  more  costly 
manufacturing  alternatives.  Each  of  these  could  have 
an adverse material impact on our business individually 
or in the aggregate. Such manufacturing issues could 
increase our cost of goods, cause us to lose revenue, 
reduce our profitability or damage our reputation.

We  rely  on  a  limited  number  of  providers  for  our  raw 
materials and supply chain services, which could result 
in  our  being  unable  to  continue  to  successfully 
commercialize our products and our product candidates 
(if approved) and to advance our clinical pipeline. 

Certain  of  the  raw  materials  required  in  the 
manufacture  and  the  formulation  of  our  products  are 
derived from biological sources. Such raw materials are 
difficult to procure and may be subject to contamination 
or recall. Access to and supply of sufficient quantities 
of raw materials which meet the technical specifications 
for  the  production  process  is  challenging,  and  often 
limited to single-source suppliers. Finding an alternative 
supplier  could  take  a  significant  amount  of  time  and 
involve  significant  expense  due  to  the  nature  of  the 
products and the need to obtain regulatory approvals. 
The  failure  of  these  single-source  suppliers  to  supply 
adequate quantities of raw materials for the production 
process  in  a  timely  manner  may  impact  our  ability  to 
produce sufficient quantities of our products for clinical 
or  commercial  requirements.  A  material  shortage, 
contamination, recall, or restriction on the use of certain 
biologically derived substances or any raw material used 
in  the  manufacture  of  our  products  could  adversely 
impact or disrupt manufacturing and materially limit our 
ability to generate revenues.

We also depend on a very limited number of third 
party providers for supply chain services with respect to 
our  clinical  and  commercial  product  requirements, 
including  product  filling,  finishing,  packaging  and 
labeling.

These third party raw material providers and supply 
chain service providers operate as independent entities 
and we do not exercise control over any such third party 
provider’s  operations  or  their  compliance  with  our 
internal  or  external  specifications  or  the  rules  and 

37

regulations  of  regulatory  agencies,  including  the  FDA, 
competent authorities of the EU Member States, or any 
other  applicable 
regulations  or  standards.  Any 
contractual remedies we may have under agreements 
with  these  parties  may  not  protect  us  from  the  harm 
suffered by our business or our patients if they fail to 
provide  material  or  perform  services  that  meet  our 
specifications. Due to the highly specialized nature of 
the  services  performed  by 
third  parties, 
particularly the supply of our raw materials, we do not 
believe that we could quickly find replacement suppliers 
or service providers and, even if we were able to identify 
additional  third  parties,  the  terms  of  any  such 
arrangement  may  not  be  favorable  to  us.  In  either  of 
these  cases,  our  revenue,  results  of  operations, 
business and reputation may be harmed and we may 
not be able to provide the therapies that our patients 
require.

these 

The success of our business may also depend on 
the security of our products while in the supply chain for 
delivery to patients, which, as noted above, is dependent 
on third-party providers. For example, if our products are 
not  fully  and  adequately  secured  from  unauthorized 
access  by  third  parties,  any  of  our  products  may  be 
tampered  with  or  contaminated.  If  our  products  were 
exposed to any tampering or contamination, or if they 
are  not  transported  in  accordance  with  the  required 
specifications, our patients may be harmed through use 
of  our  products,  and  such  harm  may  be  severe.  In 
addition,  if  the  supply  chain  is  not  secure  (or  our 
distributors do not exercise control over our products 
while in their possession), we are also at risk for our 
products to be diverted to patients other than those who 
are the intended recipient or to patients who do not have 
a prescription to receive our therapies (or it may be used 
for treatment by physicians who have not completed the 
necessary REMs protocols in order to treat patients) or 
it may be sold by distributors, channels or other entities 
that are not authorized by Alexion to sell our products. 
In addition, an unauthorized distributor may not properly 
store or ship our products, thereby exposing patients to 
potential  harm  from  use  of  the  product  that  was  not 
handled in accordance with our standards. In any of the 
foregoing were to happen, we could be subject to costly 
litigation,  significant  monetary  penalties,  harm  to  our 
reputation  and  investigation  by  regulatory  authorities 
(and potentially subject to regulatory action, including 
recall, product withdrawals, suspensions and monetary 
penalties).

The sale and use of counterfeit versions of our products 
could result in significant harm to patients, reduced sales 
of our products and harm to our reputation.

We  are  aware  that  counterfeit  versions  of  our 
products have been sold by entities that are not affiliated 
with  Alexion  using  product  packaging  suggesting  that 
the  product  was  manufactured  by  Alexion. 
If 
unauthorized  third  parties  illegally  distribute  and  sell 

handling 

counterfeit versions of our products, those products may 
not meet our very stringent product specifications (or 
the  manufacturing, 
distribution 
requirements  for  our  products)  and  any  patient  that 
takes any counterfeit product may suffer serious adverse 
health consequences, including death. Our reputation 
and business could suffer harm as a result of counterfeit 
drugs sold under our brand name and could result in 
lost sales for us and decreased revenues. 

and 

If we are unable to establish and maintain effective sales, 
marketing and distribution capabilities or to enter into 
agreements with third parties to do so, we may be unable 
to successfully commercialize our products.

We currently market and sell our products in the 
U.S., the EU Japan and several other territories through 
a direct sales force. Most of our products are relatively 
new to the market (ULTOMIRIS for the treatment of PNH 
was  approved  by  the  FDA  in  December  2018,  for 
example),  and  we  have  recently  hired  several  senior 
members of our sales and commercial team. In addition, 
in order to gain greater efficiencies in our operations, 
we have begun to implement a plan pursuant to which 
certain  portions  of  our  international  commercial 
operations will transition to a new operating model in 
which  sales  and  marketing  efforts  in  the  designated 
countries will rely to a greater extent on third-parties to 
promote  and  sell  our  products,  and  our  direct  sales 
presence will decrease in these regions.

Due to the fact that many of our products are new 
to the market, we do not have significant experience in 
marketing  and  selling  these  productions  to  patients, 
healthcare  providers  and  payers  (for  example,  we  are 
new to certain therapy areas, such as neurology (gMG), 
and our sales force has had very limited  exposure in 
educating and targeting sales to patients and physicians 
in neurology practices). This challenge is coupled with 
the fact that many of our sales and marketing team are 
new to Alexion and we are transitioning to third parties 
to market and sell our product in certain countries. If we 
are  unable  to  successfully  market  and  sell  our  new 
products and to successfully sell our products in new 
therapy  areas,  as  well  as  successfully  implement  the 
transition to third parties to distribute and market our 
products in certain countries, our business and sales 
may be harmed. One of our objectives is to expand our 
business and sales in the future. If we are unable to 
establish and/or expand our capabilities to sell, market 
and distribute our products in those jurisdictions where 
we will continue to rely on our direct sales force and, at 
the same time, effectively transition from a direct sales 
force model (or maintain such distributor capabilities in 
countries  where  we  have  already  commenced 
commercial sales), we may not be able to successfully 
sell our products. In that event, we may not be able to 
maintain or increase revenues and achieve our goal of 
expanding our business. We cannot guarantee that we 
will  be  able  to  establish  and  maintain  our  own 

38

capabilities or enter into and maintain any marketing or 
distribution  agreements  with  third-party  providers  on 
acceptable  terms,  if  at  all,  or  that  we  will  be  able  to 
manage  the  transition  to  distributors  in  the  relevant 
jurisdictions  that  will  not  cause  any  interruption  or 
disruption in our business and sales of our products. 

Even if we hire the qualified sales and marketing 
personnel necessary to support our objectives, or enter 
into  marketing  and  distribution  agreements  with  third 
parties  on  acceptable  terms,  we  may  not  hire  such 
employees or enter into such agreements in an efficient 
manner  or  on  a  timely  basis.  We  may  not  be  able  to 
forecast accurately the size and experience of the sales 
and  marketing  force  and  the  scale  of  distribution 
capabilities necessary to successfully market and sell 
our  products.  Establishing  and  maintaining  sales, 
marketing and distribution capabilities are competitive, 
expensive  and  time-consuming.  In  addition,  as  we 
launch  new  products,  such  as  ULTOMIRIS  for  the 
treatment  of  PNH,  and  we  move  into  new  therapeutic 
areas (such as neurology), and, if and when, the products 
we  acquire  in  connection  with  acquisitions  and 
development agreements with third parties move closer 
to  regulatory  approval,  we  may  have  a  larger  product 
portfolio and address more therapeutic areas and the 
foregoing  risks  may  continue  to  apply  and  may  even 
increase. Our expenses associated with building up and 
maintaining the sales force and distribution capabilities 
around the world, and in transitioning from direct sales 
to  third  party  marketers  and  distributors,  may  be 
disproportionate compared to the revenues we may be 
able to generate on sales or any savings or efficiencies 
we  gain  through  use  of  such  third-parties.  We  cannot 
guarantee that we will be successful in commercializing 
any of our products for the above referenced or other 
reasons.

Completion of proof of concept trials, preclinical studies 
or clinical trials does not guarantee advancement to the 
next  phase  of  development  or  regulatory  approval  or 
successful commercialization.

Completion of preclinical studies or clinical trials 
does  not  guarantee  that  we  will  initiate  additional 
studies  or  trials  for  our  product  candidates,  if  further 
studies or trials are initiated, what the scope and phase 
of the trial will be or that they will be completed, or if 
these further studies or trials are completed, that the 
design or results may provide a sufficient basis to apply 
for or receive regulatory approvals or to commercialize 
products. Results of clinical trials could be inconclusive, 
requiring additional or repeat trials. Data obtained from 
preclinical  studies  and  clinical  trials  are  subject  to 
varying interpretations that could delay, limit or prevent 
regulatory approval. If the design or results achieved in 
our clinical trials are insufficient to proceed to further 
trials or to regulatory approval of our product candidates, 
we could be materially adversely affected. Failure of a 
clinical trial to achieve its pre-specified primary endpoint 

generally increases the likelihood that additional studies 
or  trials  may  be  required  if  we  determine  to  continue 
development  of  the  product  candidate,  reduces  the 
likelihood  of  timely  development  of  and  regulatory 
approval  to  market  the  product  candidate,  and  may 
decrease  the  chances  for  successfully  achieving  the 
primary endpoint in scientifically similar indications.

We are currently planning and conducting several 
clinical trials of products and product candidates that 
we anticipate may be important to our goal of expanding 
our  business  and  diversifying  our  product  portfolio.  
These trials may not yield the anticipated results for a 
number of reasons.  For example, the fact that we have 
obtained  marketing  authorization  in  the  U.S.  for 
ULTOMIRIS as a treatment for PNH does not mean that 
ULTOMIRIS will be approved as a treatment for aHUS, 
gMG and NMOSD or that any clinical trials may achieve 
its  designated  endpoints  and  prove  to  be  safe  and 
effective for use in patients with these indications. In 
addition,  we  are  also  conducting  clinical  trials  in 
therapeutic areas with which we have limited experience 
(for example, in 2018 we acquired ALXN1840 (WTX101), 
a  therapy  for  Wilson’s  disease  acquired  from  Wilson 
Therapeutics and are currently in Phase III clinical trials) 
and with technology platforms with which we also have 
limited experience (for example, in 2018 we acquired 
Syntimmune  that  develops  humanized  monoclonal 
antibody  that  inhibits  the  interaction  of  FcRn  with 
Immunoglobulin  G  (IgG)  and  IgG  immune  complexes). 
Each  of  these  clinical  trials  is  subject  to  the  risks 
highlighted  in  the  preceding  paragraph  and  the 
investments we have made in these technologies may 
not generate the expected returns if the clinical trials 
do not produce results that will meet the requirements 
of  regulators  and  the  needs  of  patients  and  their 
healthcare providers.

In  addition,  we  intend  to  further  increase  the 
number  of  products  in  our  preclinical  and  early-stage 
clinical pipeline and the number of indications that our 
products  address.  For  example,  in  2019  we  plan  to 
initiate proof of concept clinical trials for ULTOMIRIS as 
a treatment for Amyotrophic Lateral Sclerosis (ALS) and 
Primary Progressive Multiple Sclerosis (PPMS). There is 
no guarantee that any proof of concept trial will provide 
sufficient evidence to advance our research beyond the 
proof of concept stage, and we may expend significant 
resources in an effort to establish proof of concept that 
ULTOMIRIS is a potential therapy for  ALS  or  PPMS or 
that  any  other  product  in  development  will  meet  the 
standard for proof of concept for other indications. In 
the  event  that  a  product  does  satisfactorily  establish 
proof of concept, and it does advance into preclinical or 
clinical  trials,  such  product  may  face  the  risks  and 
challenges identified in the preceding paragraph.

Our clinical studies may be costly and lengthy, and there 
are many reasons why drug testing could be delayed or 
terminated.

For human trials, patients must be recruited and 
each product candidate must be tested at various doses 
and formulations for each clinical indication. In addition, 
to ensure safety and effectiveness, the effects of drugs 
often  must  be  studied  over  a  long  period  of  time, 
especially for the chronic diseases that we are studying. 
Many  of  our  programs  focus  on  diseases  with  small 
patient populations making patient enrollment difficult. 
Insufficient patient enrollment in our clinical trials could 
delay or cause us to abandon a product development 
program. We may decide to abandon development of a 
product  candidate  or  a  study  at  any  time  due  to 
unfavorable results or other reasons, including if there 
are concerns about patient safety. We may have to spend 
considerable  resources  repeating  clinical  trials  or 
conducting additional trials, either of which may increase 
costs and delay revenue from those product candidates, 
if any.  We may open clinical sites and enroll patients in 
countries where or for indications in which we have little 
experience. 

We  rely  on  a  small  number  of  clinical  research 
organizations  to  carry  out  our  clinical  trial  related 
activities, and one contract research organization (CRO) 
is responsible for many of our studies. We rely on such 
parties to accurately report their results. Our reliance 
on CROs may impact our ability to control the timing, 
conduct,  expense  and  quality  of  our  clinical  trials.  In 
addition, we may be responsible for any errors in clinical 
trials by a CRO as a result of the performance of services 
in  connection  with  a  clinical  trial  on  our  behalf.    And

We may not accurately forecast demand for our products, 
including  our  new  products,  or  the  conversion  of  PNH 
patients to ULTOMIRIS, which may cause our operating 
results to fluctuate,  

Our quarterly revenues, expenses and net income 
(loss) may fluctuate, even significantly, due to certain 
risks, including those described in these “Risk Factors” 
as well as the timing of charges and expenses that we 
may  take  and  acquisitions  (such  as  the  Wilson 
Therapeutics  and  Syntimmune  acquisitions).  In  the 
future,  we  may  not  generate  sufficient  revenues  or 
control  expenses  to  achieve  our  financial  goals, 
including continued profitability. We may not be able to 
sustain or increase profitability on a quarterly or annual 
basis.  You  should  not  consider  our 
financial 
performance,  including  our  revenue  growth,  in  recent 
periods as indicative of our future performance. Since 

40

we have a limited sales and operating history with certain 
of our products (such as ULTOMIRIS as a treatment for 
PNH  in  the  US)  and  for  new  indications  of  existing 
products (such as SOLIRIS as a treatment for gMG), we 
may not be able to accurately forecast demand for our 
products. STRENSIQ and KANUMA, also relatively new 
products,  each  received  marketing  approval  in  2015, 
and both products treat rare diseases for which there 
was no existing therapy in a new therapeutic area. We 
have recently filed for regulatory approval for SOLIRIS 
as a treatment for NMOSD. Since approval of ULTOMIRIS 
as a treatment for PNH in the U.S. in December 2018, 
we have undertaken efforts to facilitate the conversion 
of PNH patients in the U.S. from SOLIRIS to ULTOMIRIS. 
Product  demand  and,  in  the  case  of  conversion  to 
ULTOMIRIS,  product  preference  and  conversion,  is 
dependent on a number of factors, many of which are 
beyond our control.  For these reasons, we may not be 
able to accurately forecast demand for our products.

We cannot guarantee that we will achieve our financial 
goals, including our ability to maintain profitability on a 
quarterly or annual basis in the future.

Our investors and investment analysts may have 
widely varying expectations that may be materially higher 
or  lower  than  actual  revenues  and  profits  and  if  our 
revenues  and  profits  are  different 
these 
expectations, our stock price may experience significant 
volatility. Our revenues and profits are also subject to 
foreign  exchange  rate  fluctuations  due  to  the  global 
nature of our operations and our results of operations 
could be adversely affected due to unfavorable foreign 
exchange rates. Although we use derivative instruments 
to manage foreign currency risk, our efforts to reduce 
currency exchange losses may not be successful. 

from 

In  addition,  we  have  in  the  past  provided,  and 
expect  to  continue  to  provide,  financial  guidance  for 
future periods and if our actual operating results fail to 
meet or exceed the guidance that we have previously 
provided  to  our  investors,  our  stock  price  could  drop 
suddenly and significantly. 

As  we  attempt  to  expand  our  pipeline,  obtain 
regulatory  approval  for  new  products,  facilitate  the 
conversion of PNH patients from SOLIRIS to ULTOMIRIS 
in  the  U.S.,  seek  regulatory  approval  for  existing 
products  in  new  jurisdictions  and  approval  of  new 
indications for existing products (such as SOLIRIS as a 
treatment  for  NMOSD),  we  may  have  substantial 
expenses as we continue our research and development 
efforts, continue to conduct clinical trials and continue 
to develop and expand manufacturing, sales, marketing 
and distribution capabilities worldwide, some of which 
could be delayed, scaled-back or eliminated to achieve 
our financial objectives.  These expenses may increase 
and  such  increases  may  exceed  analyst  and  investor 
expectations.

If we fail to achieve the expected financial and operating 
benefits of our corporate restructurings, our business and 
financial results may be harmed.

We  have  undertaken  corporate  restructuring 
activities to re-align our global organization with our re-
focused strategy, reduce costs, and realize operational 
efficiencies.  We  estimate  that  our  most  recent 
restructuring,  which includes our transition in certain 
jurisdictions from a direct sales model to increased use 
of third parties, will result in a charge of up to $25.0 in 
2019.  These  recent  restructuring  activities,  including 
work force reductions, closing certain operational sites 
and  our  increased  use  of  third  parties  in  certain 
countries  to  market  and  distribute  products  (and  rely 
less on a direct sales force), subject us to many risks, 
including  loss  of  business  continuity,  unanticipated 
costs,  and  higher  than  usual  employee  turnover.  In 
addition, we will not exercise the same degree of control 
over any third parties that we do over our direct sales 
force and the ability to direct the third party or provide 
incentives for such third party to sell our products may 
not be as strong as in the case of a direct sales force. 
The expected cost savings and operational efficiencies 
restructuring  activities  are  based  on 
from 
assumptions  and  expectations  that  we  believe  were 
reasonable in our judgment at the time made but may 
not  be  achieved  due  to  unforeseen  difficulties  and 
challenges  that  are  beyond  our  control.  If  these 
assumptions  and  expectations  are  incorrect  or  if  we 
experience delays or unforeseen events in realizing the 
benefits  of  the  restructuring  activities,  our  business 
operations and financial results may be harmed.

the 

As  we  implement  any  restructurings,  we  must 
execute  on  our  re-focused  strategy,  including  growing 
and maximizing our rare disease business and pursuing 
disciplined  business  development  to  expand  our 
pipeline.  If  we  are  unable  to  effectively  execute  with 
fewer  human  resources  and/or  attract,  retain  or 
motivate key employees, our business may be adversely 
affected.

If we fail to attract and retain highly qualified personnel, 
we may not be able to successfully develop, manufacture 
or commercialize our products or products candidates.

The success of our business is dependent in large 
part on our continued ability to attract and retain our 
senior  management,  and  other  highly  qualified 
personnel in our scientific, clinical, manufacturing and 
commercial organizations. There is intense competition 
in  the  biopharmaceutical  industry  for  these  types  of 
personnel. In March 2017, our Board appointed a new 
Chief Executive Officer (CEO) and we have experienced 
other  recent  significant  management  changes.  In 
addition,  since  2017,  we  have  moved  our  global 
headquarters 
company-wide 
restructurings  with  the  goal  of  re-aligning  our  global 
organization with our re-focused strategy and to make 
our international operations more efficient and effective. 

undertaken 

and 

The relocation of our headquarters and restructurings 
have  the  potential  to  adversely  impact  our  ability  to 
recruit and/or retain key employees as well as to disrupt 
our business operations, financial conditions, programs, 
plans and strategies.

Our business is specialized and global and we must 
attract  and  retain  highly  qualified  individuals  across 
many geographies. We may not be able to continue to 
attract  and  retain  the  highly  qualified  personnel 
necessary to develop, manufacture and commercialize 
our  products  and  product  candidates.  If  we  are 
unsuccessful in our recruitment and retention efforts, 
or if our recruitment efforts take longer than anticipated, 
our business may be harmed.

If we fail to satisfy our debt service obligations or obtain 
the capital necessary to fund our operations, we may be 
unable  to  commercialize  our  products  or  continue  or 
complete our product development.

In June 2018, we amended and restated our credit 
facility  to,  among  other  things,  increase  the  amount 
available under the revolving credit facility from $500.0 
to $1,000.0 and extend the maturity date of the revolving 
credit facility and the term loan facility to June 7, 2023. 
As a result, we have significant debt service obligations. 
In  addition  to  the  obligations  to  make  interest  and 
principal payments under the facility throughout the term 
of the loans, any changes in interest rates related to 
this debt could significantly increase our annual interest 
expense  and  any  hedging  of  this  interest  may  not  be 
effective to control expenses.

  In  addition,  we  have  substantial  contingent 
liabilities,  including  milestone  and  royalty  obligations 
under acquisitions and strategic transactions, and we 
have been, and in the future may again be, engaged in 
disputes with certain counterparties regarding potential 
milestone  and  royalty  obligations.  Our  increased 
indebtedness,  including  increased  interest  expense, 
together with our significant contingent liabilities, could, 
among other things:  

•  make  us  more  vulnerable  to  economic  or 
industry downturns and competitive pressures; 

•  make it difficult for us to make payments on our 
credit facilities and require us to use cash flow from 
operations  to  satisfy  our  debt  obligations,  which 
may reduce the availability of our cash flow for other 
purposes, including business development efforts, 
research  and  development  and  mergers  and 
acquisitions; 

•  limit our ability to incur additional debt or access 
the capital markets; and 

•  limit our flexibility in planning for, or reacting to 
changes in, our business. 

The  Amended  and  Restated  Credit  Agreement 
requires us to comply with certain financial covenants 
and negative covenants, restricting or limiting our ability 

41

and the ability of our subsidiaries to, among other things, 
incur additional indebtedness, grant liens, and engage 
in  certain  investment,  acquisition  and  disposition 
transactions, subject to limited exceptions. If an event 
of default occurs, the interest rate may increase and the 
administrative  agent  may  be  entitled  to  take  various 
actions, including the acceleration of amounts due under 
the  Amended  and  Restated  Credit  Agreement.  If  the 
interest rate imposed under our Amended and Restated 
Credit  Agreement  were  to  increase  as  a  result  of  a 
default, our expenses may increase and we may need 
to  allocate  additional  funds  to  this  interest  expense 
(which  may  limit  the  use  of  these  funds  for  other 
purposes, including growing our business or responding 
to changes in our business and industry). If some or all 
of  the  amounts  outstanding  under  the  Amended  and 
Restated Credit Agreement were to be accelerated by 
the lenders, we may not have sufficient cash on hand 
to pay the amounts due, we may not be able to refinance 
such debt on terms acceptable to us (or at all) and we 
may be required to sell certain assets on terms that are 
unfavorable to us.

Our  ability  to  satisfy  our  obligations  under  the 
Amended and Restated Credit Agreement and meet our 
debt service obligations and our royalty and milestone 
obligations  will  depend  upon  our  future  performance, 
which will be subject to financial, business and other 
factors  affecting  our  operations,  many  of  which  are 
beyond our control.

We  may  not  be  able  to  access  the  capital  and  credit 
markets on terms that are favorable to us or at all.

We  may  need  to  raise  additional  capital  to 
supplement our existing funds and cash generated from 
operations for working capital, capital expenditure and 
debt  service 
requirements,  and  other  business 
activities. Funding needs may shift and the amount of 
capital we may need depends on many factors, including, 
the  cost  of  any  acquisition  or  any  new  collaborative, 
licensing or other commercial relationships that we may 
establish,  the  time  and  cost  necessary  to  build  our 
manufacturing facilities or enhance our manufacturing 
operations, amounts we may need to pay in connection 
with the resolution of any government investigation or 
litigation  matter  (including  any  securities  class  action 
matter or any product liability claim), the cost of obtaining 
and maintaining the necessary regulatory approvals for 
our  manufacturing  facilities,  and  the  progress,  timing 
and scope of our preclinical studies, clinical trials and 
product  development  and  commercialization  efforts. 
The  capital  and  credit  markets  have  experienced  and 
may  continue  to  experience  extreme  volatility  and 
disruption. We may not receive additional funding when 
we  need  it  or  funding  may  only  be  available  on 
unfavorable terms. If we cannot raise adequate funds 
to satisfy our working capital, capital requirements and 
debt  repayment  obligations  (or  royalty  and  milestone 
obligations),  we  may  have  to  delay,  scale-back  or

research, 

Our business involves environmental risks and potential 
exposure to environmental liabilities.

 As  a  biopharmaceutical  company,  our  business 
involves the use of certain hazardous materials in our 
research,  development,  manufacturing  and  other 
activities. We and our third party providers are subject 
to  various  federal,  state  and  local  and  foreign 
environmental  laws  and  regulations  concerning  the 
handling and disposal of non-hazardous and hazardous 
wastes,  such  as  medical  and  biological  wastes,  and 
emissions and discharges into the environment, such 
as air, soils and water sources. We also are subject to 
laws and regulations that impose liability and clean-up 
responsibility for releases of hazardous substances into 
the  environment  and  a  current  or  previous  owner  or 
operator  of  property  may  be  liable  for  the  costs  of 
remediating its property or locations, without regard to 
whether the owner or operator knew of or caused the 
contamination.  Although  we  believe  that  our  safety 
procedures  for  handling  and  disposing  of  hazardous 
materials  comply  with  the  laws  and  regulations 
established by state, federal and foreign regulations, the 
risk of loss of, or accidental contamination or injury from, 
these materials cannot be eliminated. If an accident or 
environmental  discharge  occurs,  or  if  we  discover 
contamination caused by prior owners and operators of 
properties we acquire, we could be liable for remediation 
obligations, damages and fines that could exceed our 
insurance  coverage  and  financial  resources.  Such 
obligations and liabilities, which to date have not been 
material, could have a material impact on our business 
and  financial  condition.  Additionally,  the  cost  of 
compliance  with  environmental  and  safety  laws  and 
regulations may increase in the future, and we may be 
required 
including 
substantial financial resources, to comply with such laws 
and  regulations  or  purchase  supplemental  insurance 
coverage,  which  may  not  be  available  on  acceptable 
terms or at all.

to  dedicate  more 

resources, 

In order to meet one of our key business objectives of 
advancing and rebuilding our product pipeline, we plan 
to  expand  our  business  and  product  offerings  through 
acquisitions of businesses and technologies. Our efforts 
to identify opportunities or complete transactions that 
satisfy our strategic criteria may not be successful, and 
we  may  not  realize  the  anticipated  benefits  of  any 
completed acquisition or other strategic transaction.

As noted above, in 2018 a substantial portion of 
our total revenue was derived from SOLIRIS. We expect 
that  there  may  be  increased  competition  to  SOLIRIS 
from, among other products and therapies, biosimilars, 
and we are still in the very early stages of the launch of 
ULTOMIRIS in the U.S. for PNH and cannot guarantee 
that our efforts to facilitate the conversion of patients 

42

from SOLIRIS to ULTOMIRIS or to have new PNH patients 
prescribed ULTOMIRIS will be successful (or that we will 
obtain clearance for ULTOMIRIS for PNH in the EU, Japan 
and other jurisdictions). As a result, we have identified 
rebuilding  our  product  pipeline  as  a  key  strategic 
objective  and,  in  order  to  achieve  this  objective,  we 
expect to purchase businesses and acquire, co-develop 
or license technologies and products from third parties 
in  the  future.  For  example,  in  2018,  among  other 
transactions,  we  completed  acquisitions  of  Wilson 
Therapeutics and Syntimmune, Inc. We anticipate that 
we will regularly evaluate potential merger, acquisition, 
partnering  and  in-license  opportunities  in  an  effort  to 
expand our pipeline or product offerings, and enhance 
our research platforms. Acquisitions of new businesses 
or  products  and  in-licensing  of  new  technologies  and 
products may involve numerous risks, including:

•  substantial cash expenditures;

•  potentially dilutive issuance of equity securities 
and incurrence of debt;

•  assumption of material liabilities in connection 
with the target or purchased technology, some of 
which may be difficult or impossible to identify at 
the time of acquisition;

•  difficulties in assimilating the operations of the 
acquired companies;

•  failure of any acquired businesses or products 
or in-licensed products or technologies to achieve 
the scientific, medical, commercial or other results 
we anticipate;

•  diverting our management’s attention away from 
other business opportunities and concerns;

•  the potential loss of our key employees or key 
employees of the acquired companies; and

•  risks of entering disease areas and indications 
in which we have limited or no direct experience.

A substantial portion of our strategic efforts are 
focused  on  opportunities  for  rare  disorders,  but  the 
availability of such opportunities is limited. We may not 
be able to identify opportunities that satisfy our strategic 
criteria  or  are  acceptable  to  us  or  our  stockholders. 
Several companies have publicly announced intentions 
to establish or develop rare disease programs and we 
may  compete  with  these  companies  for  the  same 
opportunities. For these and other reasons, we may not 
be  able  to  acquire  the  rights  to  additional  product 
candidates or approved products on terms that we or 
our stockholders find acceptable, or at all. In such event, 
we may not be able to rebuild our pipeline and any future 
revenue may remain largely dependent on our existing 
products  which,  as  noted  above,  may  be  subject  to 
increasing  competition  from  biosimilars  and  other 
competitive or novel therapies.

Even  if  we  are  able  to  successfully  identify  and 
complete acquisitions and other strategic transactions, 

43

we may not be able to integrate or take full advantage 
of  them.  An  acquisition  or  other  strategic  transaction 
may not result in short-term or long-term benefits to us. 
We may also incorrectly judge the value or worth of an 
acquired  company  or  business  or  an  acquired  or  in-
licensed product, particularly if the acquired technology 
is preclinical trials or early-stage clinical trials.

To  effectively  manage  our  current  and  future 
potential  growth,  we  must  continue  to  effectively 
enhance and develop our global employee base and our 
operational  and  financial  processes.  Supporting  our 
require  significant  capital 
growth  strategy  may

investments  in  research,  development,  sales  and 
marketing,  manufacturing  and  other  areas  of  our 
operations.  The  development  or  expansion  of  our 
business, any acquired business or any acquired or in-
licensed  products  may  require  a  substantial  capital 
investment  by  us  and  we  may  likely  incur  substantial

expenses 
commercialization.  We  may  not  have  the  necessary 
funds for these capital expenditures and expenses or 
they might not be available to us on acceptable terms 
or at all. We may also seek to raise funds by incurring 
additional indebtedness and selling shares of our capital 
stock,  which  could  dilute  current  stockholders’ 
ownership  interest  in  our  company,  or  securities 
convertible  into  our  capital  stock,  which  could  dilute 
current  stockholders’  ownership  interest  in  us  upon 
conversion.

in  advancing  acquired  products 

We  may  incur  impairment  charges  in  the  future  for 
certain  of  our  assets,  including  goodwill  in  connection 
with acquisitions, and such amounts may be material.

If  the  purchase  price  of  a  business  acquisition 
exceeds the value of the assets (and liabilities) acquired, 
the acquirer must recognize goodwill in such amount. 
We may be required to recognize impairment charges 
for our goodwill and other intangible assets, and such 
charges may be material and have an adverse impact 
on our financial results in the period such charges are 
incurred.

As of December 31, 2018, the net carrying value 
of our goodwill and other intangible assets, net totaled 
$8,678.7. As required by GAAP, we periodically assess 
these  assets  to  determine  if  there  are  indicators  of 
impairment.  We  have  recorded  charges  that  include 
inventory write-downs for failed quality specifications or 
recalls,  impairments  with  respect  to  investments  and 
acquisitions,  fixed  assets  and  long-lived  assets, 
outcomes of litigation and other legal or administrative 
proceedings, regulatory matters and tax matters, and 
payments  in  connection  with  acquisitions  and  other 
business  development  activities,  such  as  milestone 
payments.  The  impairment  of  tangible  and  intangible 
assets may be triggered by developments both within 
and  outside  our  control.  Deteriorating  economic

business,  inability  to  effectively  integrate  acquired 
businesses, unexpected significant changes or planned

in  the  use  of  the  assets, 
changes 
competition, divestitures, market capitalization declines 
and  other  factors  may  impair  our  goodwill  and  other 
intangible  assets. Any  charges 
to  such 
impairments  could  adversely  affect  our  results  of 
operations  in  the  periods  in  which  an  impairment  is 
recognized.  As  part  of  our  standard  quarterly 
procedures,  we  reviewed  the  KANUMA  asset  as  of 
December 31, 2018 and determined that there were no 
indicators of impairment. We will continue to review the 
related valuation and accounting of this asset in future 
quarters as new information becomes available to us. 
Changes  to  assumptions  used  in  our  net  cash  flow 
projections  may  result  in  impairment  charges  in 
subsequent periods. The net book value of the KANUMA 
intangible asset as of December 31, 2018 is $3,252.6.

elsewhere  in  this  Annual  Report  on  Form  10-K  for 
information  on  our  material  legal  proceedings.    For 
example,  in  May  2015,  we  received  a  subpoena  in 
connection  with  an  investigation  by  the  Enforcement 
Division of the SEC requesting information related to our 
grant-making activities and compliance with the FCPA in 
various  countries.  In  addition,  in  October  2015,  we 
received  a  request  from  the  DOJ  for  the  voluntary 
production  of  documents  and  other 
information 
pertaining to Alexion’s compliance with FCPA. The SEC 
and  DOJ  also  seek  information  related  to  Alexion’s 
recalls of specific lots of Soliris and related securities 
disclosures.  Alexion 
these 
investigations.    The  investigations  have  focused  on 
operations 
including  Brazil, 
Colombia,  Japan,  Russia  and  Turkey,  and  Alexion's 
compliance with the FCPA and other applicable laws. Any 
determination that our operations or activities are not 
in compliance with existing laws or regulations, by the 
SEC or DOJ in the above referenced matter for example, 
could result in the imposition of fines, civil and criminal 
penalties, equitable remedies, including disgorgement, 
injunctive relief, exclusion from the federal healthcare 
programs,  healthcare  debarment,  product  recalls, 
reputational damage and modifications of our business 

in  various  countries, 

is  cooperating  with 

practices  and/or  other  sanctions  against  us,  and 
remediation of any such findings could have an adverse 
effect on our business operations. Legal proceedings, 
government investigations, including the SEC and DOJ 
investigations, and enforcement actions have been and 
we  expect  may  continue  to  be  expensive  and  time 
consuming. Any future litigation or investigation may also 
likely be expensive and time consuming.

The efficiency of our corporate structure depends on the 
application  of  the  tax  laws  and  regulations  in  the 
countries where we operate and we may have exposure 
to additional tax liabilities or our effective tax rate could 
increase,  which  could  have  a  material  impact  on  our 
results of operations and financial position.

As a company with international operations, we are 
subject to income taxes, as well as non-income based 
taxes, in both the U.S. and various foreign jurisdictions. 
Significant  judgment  is  required  in  determining  our 
worldwide  tax  liabilities.   Although  we  believe  our 
estimates are reasonable at the time made, the final 
taxes we owe may differ from the amounts recorded in 
our financial statements (and such differences may be 
material). If the IRS, or other taxing authority, disagrees 
with the positions we take, we could have additional tax 
liability, and this could have a material impact on our 
results of operations and financial position. Our effective 
tax rate could be adversely affected by changes in the 
mix of earnings in countries with different statutory tax 
rates, changes in the valuation of deferred tax assets 
and  liabilities,  changes  in  tax  laws  and  regulations, 
changes in interpretations of tax laws, including pending 
tax law changes, changes in our manufacturing activities 
and  changes  in  our  future  levels  of  research  and 
development spending.

We have designed, and from time to time we modify, 
our corporate structure, the manner in which we develop 
and use our intellectual property, and our intercompany 
transactions  between  our  affiliates  in  a  way  that  is 
intended  to  enhance  our  operational  and  financial 
efficiency  and  increase  our  overall  profitability.  The 
application of the tax laws and regulations of various 
countries  in  which  we  operate  and  to  our  global 
operations  is  subject  to  interpretation.  We  also  must 
operate our business in a manner consistent with our 
corporate structure to realize such efficiencies. The tax 
authorities  of  the  countries  in  which  we  operate  may 
challenge  our  methodologies  for  valuing  developed 
technology or for transfer pricing or other operations. If 
tax authorities determine that the manner in which we 
operate  results  in  our  business  not  achieving  the 
intended tax consequences, our effective tax rate could 
increase (and such increase may be material) and harm 
our  financial  position  and  results  of  operations.  In 
addition, certain governments are considering and may 
adopt tax reform measures that significantly increase 
our  worldwide  tax  liabilities.  The  Organization  for 
Economic  Co-operation  and  Development  and  other 

44

government bodies have focused on issues related to 
the taxation of multinational corporations, including, in 
the  area  of  “base  erosion  and  profit  shifting,”  where 
payments are made from affiliates in jurisdictions with 
high tax rates to affiliates in jurisdictions with lower tax 
rates. It is possible that these reform measures could 
increase our effective tax rate (and such increase may 
be material) and harm our financial position and results 
of operations over the next several years.

Our sales and operations are subject to a variety of risks 
relating to the conduct of our international business.

We  have  increased  our  international  presence, 
including in emerging markets. Our operations in foreign 
countries subject us to a variety of risks, including:

•  difficulties  or  the  inability  to  obtain  necessary 
foreign regulatory or reimbursement approvals of 
our products in a timely manner or at all;

•  political or economic determinations that adversely 

impact pricing or reimbursement policies;

•  economic problems or political instability;

•  fluctuations in currency exchange rates;

•  difficulties  or  inability  to  obtain  financing  in 

markets;

•  unexpected changes in tariffs, trade barriers and 

regulatory requirements;

•  customs  and  tax  officials  in  foreign  jurisdictions 
may  disagree  with  the  value  we  set  when  we  or 
others import our products (including products that 
are donated for charitable purposes) and we may 
be required to pay additional duties or fines and 
such amounts may be substantial;

•  difficulties 

in  establishing  and  enforcing 

contractual and intellectual property rights;

•  compliance with complex import and export control 

laws;

•  trade  restrictions  and  restrictions  on  direct 

investments by foreign entities;

•  compliance with tax, employment and labor laws;

•  costs  and  difficulties  in  recruiting  and  retaining 
qualified managers and employees to manage and 
operate the business in local jurisdictions;

•  costs and difficulties in managing and monitoring 

international operations; and

•  longer payment cycles.

Additionally, our business and marketing methods 
are subject to the laws and regulations of the countries 
in which we operate, which may differ significantly from 
country to country and may conflict with U.S. laws and 
regulations.  The  FCPA  and  anti-bribery  laws  and 
regulations  in  the  locations  in  which  we  operate  our 
business are extensive and far-reaching, and we must 
maintain accurate records and control over the activities 

laws 

remedies, 

for  actions 

of our distributors and third party service providers in 
countries  where  we  operate.  We  have  policies  and 
procedures,  and  we  are  currently  implementing  an 
enhanced company-wide compliance program and effort, 
designed to help ensure that we and our representatives, 
including  our  employees  and  our  vendors  and 
distributors, comply with such laws, however we cannot 
guarantee  that  these  policies  and  procedures  will 
protect us against liability under the FCPA or other anti-
bribery 
taken  by  us  or  our 
representatives. Any determination that our operations 
or activities are not in compliance with existing laws or 
regulations, including the FCPA and the UK Anti-Bribery 
Act,  could  result  in  the  imposition  of  fines,  civil  and 
criminal  penalties,  equitable 
including 
disgorgement, injunctive relief, and/or other sanctions 
against us, and remediation of such findings could have 
a  material  and  adverse  effect  on  our  business 
operations. In addition, as our international operations 
expand,  we  are  likely  to  become  subject  to  new  anti-
corruption/anti-bribery laws or existing laws may govern 
our activities in new jurisdictions in which we operate. 
In addition, as we move from a direct sales force to third-
party distributors and marketers in certain countries and 
regions, we may also have liability under the FCPA and 
anti-bribery  laws  and  regulations  for  their  actions. 
Although we can impose contractual restrictions on what 
they are authorized to do on our behalf, we will exercise 
only limited control over the actions of these third parties 
but may still face the same liabilities for their actions. 
Our failure, and the failure of others who we engage to 
act  on  our  behalf,  to  comply,  with  the  laws  and 
regulations of the countries in which we operate, or will 
operate  in  the  future,  could  materially  harm  our 
business.

Currency  fluctuations  and  changes  in  exchange  rates 
could  adversely  affect  our  revenue,  increase  our  costs 
and negatively affect our profitability.

We conduct a substantial portion of our business 
in currencies other than the U.S. dollar. We are exposed 
to fluctuations in foreign currency exchange rates and 
such  fluctuations  affect  our  operating  results.  The 
exposures result from portions of our revenues, as well 
as  the  related  receivables,  and  expenses  that  are 
denominated  in  currencies  other  than  the  U.S.  dollar, 
including  the  Euro,  Japanese  Yen,  British  Pound, 
Canadian  dollar    and  Turkish  Lira.  As  the  U.S.  dollar 
strengthens  against  these  foreign  currencies,  the 
relative value of sales made in the respective foreign 
currencies  decrease.  When  the  U.S.  dollar  weakens 
against these currencies, the relative value of such sales 
increase. We manage a portion of our foreign currency 
transaction risk within specified guidelines through the 
use of derivatives. All of our derivative instruments are 
utilized for risk management purposes, and we do not 
use  derivatives  for  speculative  trading  purposes.  We 
enter into foreign exchange forward contracts to hedge 
exposures  resulting  from  portions  of  our  forecasted 

45

revenues,  including  intercompany  revenues  that  are 
denominated  in  currencies  other  than  the  U.S. 
dollar. The purpose of the revenue hedges is to reduce 
the  volatility  of  exchange  rate  fluctuations  on  our 
operating  results  and  to  increase  the  visibility  of  the 
foreign  exchange  impact  on  forecasted  revenues. 
Further,  we  enter  into  foreign  exchange  forward 
contracts,  with  durations  of  approximately  30  days, 
designed  to  limit  the  balance  sheet  exposure  of 
monetary  assets  and  liabilities. We  enter  into  these 
hedges  to  reduce  the  impact  of  fluctuating  exchange 
rates  on  our  operating  results.  Gains  and  losses  on 
these hedge transactions are designed to offset gains 
and  losses  on  underlying  balance  sheet  exposures. 
While  we  attempt  to  hedge  certain  currency  risks, 
currency fluctuations between the U.S. dollar and the 
currencies in which we do business have, in the past, 
caused foreign currency transaction gains and losses 
and have also impacted the amounts of revenues and 
expenses calculated in U.S. dollars and will do so in the 
future.  Likewise,  past  currency  fluctuations  have  at 
times resulted in foreign currency transaction gains, and 
there  can  be  no  assurance  that  these  gains  can  be 
reproduced. Any significant foreign currency exchange 
rate  fluctuations  could  adversely  affect  our  financial 
condition and results of operations.

Risks Related to the Regulatory Environment 

We operate in a highly regulated industry and if we or 
our  third  party  providers  fail  to  comply  with  U.S.  and 
foreign regulations, we or our third party providers could 
lose our approvals to market our products or our product 
candidates, and our business may be seriously harmed.

We and our current and future third party vendors, 
contract  manufacturers,  CROs,  distributors  and 
suppliers and logistic providers are subject to rigorous 
and  extensive  regulation  by  governmental  authorities 
around the world, including the FDA, EMA, the competent 
authorities  of  the  EU  Member  States  and  the  MHLW. 
These regulations, many of which are complex, relate to 
almost all aspects of our business, including GCP, GLP, 
cGMP  and  pharmacovigilance  rules  (for  additional 
information on the regulations relating to our business, 
see “Business - Government Regulation” in Item 1 above 
in this Annual Report on Form 10-K). If we or a regulatory 
agency  discover  previously  unknown  problems  with  a 
product,  such  as  adverse  events  of  unanticipated 
severity or frequency, or problems with the facility where 
the  product 
(such  as  product 
contamination),  or  in  the  case  of  KANUMA,  problems 
with animal operations, a regulatory agency may impose 
restrictions on that product, the manufacturing facility 
or us. We have received a Warning Letter from the FDA 
relating to compliance with FDA’s cGMP requirements at 
one of our facilities, which was remediated. If we had 
failed to address the FDA’s concerns or if we (or one of 
our third party contract manufacturers) were to receive 

is  manufactured 

another Warning Letter in the future relating to cGMP or 
other applicable regulations, the FDA or other regulatory 
authorities could take regulatory action, including fines, 
civil penalties, recalls, seizure of product, suspension 
of  manufacturing  operations,  operating  restrictions, 
injunctions, suspension of clinical trials, withdrawal of 
FDA approval and/or criminal prosecution. 

If  we  or  our  third-party  providers,  including  our 
product fill-finish providers, packagers and labelers, fail 
to comply fully with applicable regulations, then we may 
be  required  to  initiate  a  recall  or  withdrawal  of  our 
products. In addition to our manufacturing operations 
and  those  of  contract  manufacturers’  manufacturing 
operations  being  subject  to  inspection  and  potential 
regulatory action for failure to comply with (among other 
regulations) cGMP, our animal operations may also be 
subject  to  FDA  and  U.S.  Department  of  Agriculture, 
Animal  and  Plant  Health  Inspection  Service  (USDA 
APHIS)  inspection  to  evaluate  whether  our  animal 
husbandry, containment, personnel, and record keeping 
practices are sufficient to ensure safety and security of 
our transgenic chickens and animal products (e.g., eggs, 
waste, etc.). Any failure to ensure safety and security of 
our transgenic chickens and/or animal products could 
result  in  regulatory  action  by  the  FDA  or  another 
regulatory body, including USDA APHIS.

Failure to comply with the laws and requirements, 
including statutes and regulations, administered by the 
FDA, the EC, the competent authorities of the EU Member 
States, the MHLW or other agencies, could result in:

•  a product recall;

•  a product withdrawal;

•  significant  administrative  and  judicial  sanctions, 

including, warning letters or untitled letters;

•  significant fines and other civil penalties;

•  suspension, variation or withdrawal of a previously 

granted approval for our products;

•  interruption of production;

•  operating  restrictions,  such  as  a  shutdown  of 
production  facilities  or  production  lines,  or  new 
manufacturing requirements;

•  suspension or termination of ongoing clinical trials;

•  delays  in  approving  or  refusal  to  approve  our 
products 
including  pending  BLAs  or  BLA 
supplements  for  our  products  or  a  facility  that 
manufactures our products;

•  seizing or detaining product;

•  requiring us or our partners to enter into a consent 
decree,  which  can  include  imposition  of  various 
fines, 
inspection  costs, 
required  due  dates  for  specific  actions  and 
penalties for noncompliance; 

reimbursements 

for 

•  injunctions; and/or

46

•  criminal prosecution.

In  addition,  we  are  subject  to  antitrust 
regulations with respect to our acquisitions, as well as 
our interactions with other participants in the markets 
we serve.  In addition, these antitrust laws are vigorously 
enforced in the U.S. and in other jurisdictions in which 
we operate.  

Our product candidates require extensive clinical testing 
and  regulatory  approval  and  failure  of  to  satisfy 
regulatory requirements to meet the appropriate safety 
and efficacy thresholds may prevent us from being able 
to market our products and limit our ability to grow our 
business and diversify our revenue.

We believe our future success may depend on our 
ability  to  develop  and  commercialize  our  product 
candidates and, to this end, we have recently acquired 
companies and technologies in an effort to expand our 
product pipeline. Our product candidates are in various 
stages of development and must satisfy the rigid safety 
and efficacy requirements of the FDA and other foreign 
regulatory agencies before they can be approved for sale 
to patients. To satisfy these standards, we must ensure, 
among  other  things,  that  we  have  appropriately 
established  our  protocol  designs,  obtained 
the 
necessary  IRB  approval,  provide  adequate  patient 
enrollment  rates,  timely  and  appropriately  report  any 
adverse  events  and  serious  adverse  events  to  the 
appropriate  authorities  and  ensure  compliance  with 
cGCP.  If  we  or  our  third-party  clinical  trial  providers  or 
third-party  CROs  do  not  successfully  carry  out  these 
clinical  activities,  our  clinical  trials  or  the  potential 
regulatory  approval  of  a  product  candidate  may  be 
delayed or be unsuccessful.

If we discover safety or safety reporting issues with any 
of  our  approved  products,  or  if  we  fail  to  comply  with 
continuing U.S. and applicable foreign regulations, our 
revenue may decrease, an approved product could lose 
its marketing approval or sales could be suspended and 
our business could be materially harmed.

Following marketing approval of a pharmaceutical 
product, the safety profile of such product continues to 
be  closely  monitored  by  the  FDA  and  other  foreign 
regulatory  authorities.  Regulations  continue  to  apply 
after product approval, and cover, among other things, 
testing, manufacturing, quality control, finishing, filling, 
labeling, advertising, promotion, risk mitigation, adverse 
event  reporting  requirements  and  export  of  biologics. 
For  example,  the  REMS  program  for  SOLIRIS,  most 
recently  updated  by  the  FDA  in  2015,  requires 
prescribing  information  regarding  the  level  of  fever 
needed to seek medical attention and reporting adverse 
events. Future changes to the SOLIRIS REMS (or similar 
requirements  for  other  products)  could  be  costly  and 
burdensome to implement.

 We  are  required  to  report  any  serious  and 
unexpected  adverse  experiences  and  certain  quality 

47

problems  with  our  products  to  the  FDA,  the  EMA,  the 
MHLW and other health agencies. Adverse safety events 
involving our products may have a negative impact on 
our  business.  Discovery  of  safety  issues  with  our 
products could result in product liability claims and could 
cause additional regulatory scrutiny and requirements 
for additional labeling or safety monitoring, withdrawal 
of products from the market and the imposition of fines 
or  criminal  penalties. 
In  addition,  governmental 
authorities  are  making  greater  amounts  of  safety 
information  directly  available  to  the  public  through 
periodic  safety  update  reports,  patient  registries  and 
other reporting requirements. The reporting of adverse 
safety events may also damage physician, patient and/
or  investor  confidence  in  our  products  and  our 
reputation. Any adverse events in connection with the 
use  of  our  products  could  result  in  liabilities,  loss  of 
revenues,  material  write-offs  of  inventory,  material 
impairments  of  intangible  assets,  goodwill  and  fixed 
assets,  material  restructuring  charges  and  other 
adverse impacts on our results of operations.

Regulatory  agencies  periodically 

inspect  our 
pharmacovigilance  processes. 
If  these  regulatory 
agencies determine that we or other parties whom we 
do  not  control  that  perform  services  on  our  behalf, 
including clinical trial investigators, have not complied 
with the applicable reporting or other pharmacovigilance 
requirements,  we  may  become  subject  to  additional 
inspections,  warning  letters  or  other  enforcement 
actions, 
fines,  marketing 
including  monetary 
authorization withdrawal and other penalties.

As  a  condition  of  approval  for  marketing  our 
products,  governmental  authorities  may  require  us  to 
conduct  additional  studies.  In  connection  with  the 
approval of SOLIRIS in the U.S., EU and Japan, for the 
treatment of PNH, we agreed to establish a PNH Registry, 
monitor  immunogenicity,  monitor  compliance  with 
vaccination requirements, and determine the effects of 
anticoagulant withdrawal among PNH patients receiving 
eculizumab,  and,  specifically  in  Japan,  we  agreed  to 
conduct  a  trial  in  a  limited  number  of  Japanese  PNH 
patients  to  evaluate  the  safety  of  a  meningococcal 
vaccine. In connection with the approval of SOLIRIS in 
the  U.S.  for  the  treatment  of  aHUS,  we  agreed  to 
establish  an  aHUS  Registry  and  complete  additional 
human clinical studies in adult and pediatric patients. 
Furthermore,  in  connection  with  the  approval  of 
STRENSIQ  in  the  U.S.,  we  agreed  to  conduct  a 
prospective observational study in treated patients to 
assess the long-term safety of STRENSIQ therapy and 
to  develop  complementary  assays.  Similarly, 
in 
connection with the approval of KANUMA in the U.S., we 
agreed  to  conduct  a  long-term  observational  study  of 
treated patients, either as a standalone study or as a 
component  of  the  existing  LAL  Registry.  In  the  EU,  in 
connection with the grant of authorization for STRENSIQ, 
we agreed to conduct a multicenter, randomized, open-
label, Phase 2a study of STRENSIQ in patients with HPP 

 
and to extend the studies ENB-008-10 and ENB-009-10 
to provide efficacy data in patients 13 to 18 years of 
age, which we have commenced.

In the U.S., the FDA can also propose to withdraw 
approval  for  a  product  if  it  determines  that  such 
additional studies are inadequate or if new clinical data 
or information shows that a product is not safe for use 
in an approved indication.

In addition, similar or more stringent post-approval 
requirements and obligations may be imposed by the 
FDA  and/or  other  regulatory  agencies  with  respect  to 
our future products (such as ULTOMIRIS or SOLIRIS for 
the treatment of NMOSD, if approved for use by the FDA 
and  such  agencies).  Compliance  with  these  post-
approval  requirements  could  result  in  increased  cost 
and expense and decrease our operating margins and, 
if we are unable to comply with these requirements, we 
may  be  subject  to  regulatory  action  by  the  applicable 
regulatory agency and the penalties may include fines 
and product withdrawals or restrictions in the use of a 
product. 

If we fail to comply with applicable healthcare laws  and 
regulations, including those related to healthcare fraud 
and abuse, we may be subject to investigations and civil 
or criminal penalties and our business could be adversely 
affected. 

We are subject to healthcare “fraud  and  abuse” 
laws, such as the FCA, the anti-kickback provisions of 
the federal Social Security Act, laws prohibiting off-label 
product promotion and other related federal and state 
laws and regulations. 

item  or  service 

The federal Anti-Kickback Statute prohibits, among 
other  things,  knowingly  and  willfully  offering,  paying, 
soliciting  or  receiving  any  remuneration,  directly  or 
indirectly,  in  cash  or  in  kind  to  induce,  or  reward  the 
purchasing,  leasing,  ordering  or  arranging  for  or 
recommending  the  purchase,  lease  or  order  of  any 
reimbursable  under 
healthcare 
federal  healthcare 
Medicare,  Medicaid,  or  other 
programs. Liability may be established without a person 
or  entity  having  actual  knowledge  of  the  federal  Anti-
Kickback  Statute  or  specific  intent  to  violate  it.  A 
conviction  for  violation  of  the  Anti-kickback  Statute 
requires  mandatory  exclusion  from  participation  in 
federal healthcare programs. The majority of states also 
have  statutes  similar  to  the  federal  Anti-Kickback 
Statute and false claims laws that apply to items and 
services  reimbursed  under  Medicaid  and  other  state 
programs, or, in several states, apply regardless of the 
payer.  

The  FCA  prohibits  any  person  from  knowingly 
presenting,  or  causing  to  be  presented,  a  false  or 
fraudulent claim for payment of government funds, or 
knowingly making, using or causing to be made or used, 
a  false  record  or  statement  material  to  a  false  or 
fraudulent claim. Pharmaceutical companies have been 

48

investigated  and  have  reached  substantial  financial 
settlements with the Federal government under the FCA 
for  a  variety  of  alleged  promotional  and  marketing 
activities,  such  as  allegedly  providing  free  product  to 
customers  with  the  expectation  that  the  customers 
would  bill  federal  programs  for  the  product;  providing 
consulting  fees  and  other  benefits  to  physicians  to 
induce  them  to  prescribe  products;  engaging  in 
promotion of pharmaceuticals for uses that the FDA has 
not approved, or “off-label” uses; and submitting inflated 
best price information to the Medicaid Rebate Program. 

We seek to comply with the Anti-Kickback Statute 
and FCA laws, including operating within any available 
safe harbors, but we cannot assure that our compliance 
program, policies and procedures will always protect us 
from  acts  committed  by  its  employees  or  third-party 
distributors or service providers. 

Other 

related 

federal  and  state 

laws  and 
regulations that may affect our ability to operate include, 
among others, the federal False Statements Statute, the 
federal Civil Monetary Penalties Law, HIPAA, the federal 
Open Payments program, state anti-kickback and false 
claims acts, and state and local disclosure requirements 
and marketing restrictions. Additional information about 
the scope of these requirements and potential penalties 
is provided under “Government Regulation - Fraud and 
Abuse” included above in Item 1 in this Annual Report 
on Form 10-K.

level 

local 

In  recent  years,  legislation  has  been  adopted  at 
the 
requiring 
federal,  state  and 
pharmaceutical  companies  to  establish  marketing 
compliance  programs,  file  periodic  reports  or  make 
periodic public disclosures on sales, marketing, pricing, 
clinical trials, health care provider payments and other 
activities. For example, as part of the PPACA, the federal 
government  enacted  the  Open  Payments  (commonly 
known as the Sunshine Act) provisions. Open Payments 
requires  pharmaceutical  manufacturers 
report 
annually to CMS payments or other transfers of value 
made by that entity to physicians and teaching hospitals. 
We  also  now  have  similar  reporting  obligations 
throughout the EU.  Failure to comply with the reporting 
requirements  may  result  in  significant  civil  monetary 
penalties.

jurisdictions)  may 
in  criminal,  civil  and 
administrative sanctions, including fines, damages, civil 
monetary penalties (which may be material in amount) 
and  exclusion  from  federal  healthcare  programs 
(including Medicare and Medicaid). Any action initiated 
against  us  for  violation  of  these  laws,  even  if  we 
successfully  defend  against  it,  could  require  the 
expenditure  of  significant  resources  and  generate 
negative  publicity,  which  could  materially  adversely 
affect  our  ability  to  operate  our  business  and  our 
financial results.

Finally, the FDA, the EU and EU Member States and 
the  MHLW  impose  restrictions  on  the  promotion  and 
marketing of drug products and prohibit pharmaceutical 
manufacturers from promoting products for indications 
other  than  those  cleared  or  approved  by  regulatory 
authorities or for use in manner that is not consistent 
with the product label approved by regulatory agencies, 
or off-label promotion. In certain instances, physicians 
are, however, in their medical judgment permitted to use 
products for unapproved purposes and we are aware of 
such uses of SOLIRIS. For information regarding a recent 
MHLW  inquiry  focused  on  our  communication  efforts 
regarding the proper use of SOLIRIS in Japan for aHUS, 
see Note 11 “Commitments and Contingencies” to our 
consolidated financial statements included elsewhere 
in this Annual Report on Form 10-K. Although we believe 
our  marketing  materials  and  training  programs  for 
physicians  do  not  constitute  improper  promotion,  the 
FDA, the U.S. Department of Justice (DOJ), other federal 
or  state  government  agencies,  the  EU,  EU  Member 
States or the MHLW may disagree. If any governmental 
authority  determines  that  our  promotional  materials, 
training or other activities constitute improper promotion 
of any of our products, it could request that we modify 
our training or promotional materials or other activities 
or  subject  us  to  regulatory  enforcement  actions, 
including  the  issuance  of  a  warning  letter,  product 
withdrawal  or  recall,  injunction,  seizure,  civil  fine  and 
criminal  penalties.  It  is  also  possible  that  other 
enforcement authorities might take action if they believe 
that  the  alleged  improper  promotion  led  to  the 
submission and payment of claims for an unapproved 
use, which could result in significant fines or penalties 
under  other  statutory  authorities,  such  as  laws 
prohibiting  false  or  fraudulent  claims  for  payment  of 
government funds.

The  sales  and  marketing  practices  of  the 
pharmaceutical  industry  have  been  the  subject  of 
increased scrutiny from authorities such as the DOJ, and 
we  expect  that  this  trend  may  continue  and  may 
increase. If the government or the courts determine that 
we breached any of these sales and marketing laws, we 
may be subject to penalties identified above. Any action 
against  us  for  violation  of  these  laws,  even  if  we 
successfully defend against them, also could cause us 
to incur significant legal expenses, harm our reputation 
and  divert  our  management’s  attention  from  the 
operation of our business.

Our business and operations may be materially adversely 
affected by government investigations. 

We are subject to the FCPA, the U.K. Bribery Act 
and  other  anti-corruption  laws  and  regulations  that 
generally  prohibit  companies  and  their  intermediaries 
from making improper payments to government officials 
and/or  other  persons  for  the  purpose  of  obtaining  or 
retaining business and we operate in countries that are 
for 
recognized  as  having  a  greater  potential 

49

governmental and commercial corruption. While we have 
enhanced  our  compliance  and  training  programs,  we 
cannot  assure  that  our  compliance  program,  policies 
and  procedures  will  always  protect  us  from  acts 
committed by employees or third-parties acting on our 
behalf.

In  May  2015,  we  received  a  subpoena  in 
connection  with  an  investigation  by  the  Enforcement 
Division of the SEC requesting information related to our 
grant-making activities and compliance with the FCPA in 
various  countries.  In  addition,  in  October  2015,  we 
received  a  request  from  the  DOJ  for  the  voluntary 
production  of  documents  and  other 
information 
pertaining  to  our  compliance  with  the  FCPA.  The  SEC 
and DOJ also sought information related to our recalls 
of  specific  lots  of  SOLIRIS  and  related  securities 
disclosures.  In  December  2016,  we  received  a 
subpoena from the U.S. Attorney’s Office for the District 
of  Massachusetts  requesting  documents  relating 
to  our  support  of  certain  501(c)(3) 
generally 
organizations (as described below). We understand that 
the U.S. Attorney's Office is coordinating its inquiry with 
the  Office  of  Inspector  General  (OIG)  of  the  U.S. 
Department  of  Health  and  Human  Services.  In  May 
2017, Brazilian authorities seized records and data from 
our Sao Paulo, Brazil offices as part of an investigation 
being conducted into our Brazilian operations. In October 
2018,  the  MHLW  conducted  an  inspection  of  our 
Japanese  operations.  We  are  cooperating  with  these 
investigations. At this time, we are unable to predict the 
duration, scope or outcome of these investigations.

Any determination that our operations or activities 
are not, or were not, in compliance with existing U.S. or 
foreign laws or regulations, could result in the imposition 
of a broad range of civil and criminal sanctions against 
us  and  certain  of  our  directors,  officers  and/or 
employees,  including  injunctive  relief,  disgorgement, 
substantial fines or penalties, imprisonment, and other 
legal  or  equitable  sanctions,  including  exclusion  from 
Medicare, Medicaid, and other governmental healthcare 
programs. Any attempts to resolve some or all of these 
matters may not be successful.  If we were to engage 
in settlement discussions with respect to any current or 
future  investigation  or  litigation  (and  we  may  accrue 
amounts due to the nature of such discussions), but the 
matter is not settled, the ultimate resolution may result 
in  monetary  or  other  penalties  materially  stricter  or 
greater than the terms or amounts that we proposed in 
discussions (or the amount that we accrued for such 
matter during negotiations).  For example, in connection 
with the investigation by the U.S. Attorney's Office for 
the District of Massachusetts relating generally to our 
support  of  Patient  Services,  Inc.  (PSI)  and  National 
Organization  for  Rare  Disorders  (NORD),  501(c)(3) 
organizations  that  provide  financial  assistance  to 
Medicare patients taking drugs sold by Alexion (among 
other matters) we have accrued approximately $13.0 in 
the fourth quarter of 2018 as a result of our agreement 

in principle to settle this investigation (but there is no 
guarantee  that  the  steps  necessary  to  conclusively 
resolve  this  matter  will  be  successful  or  that  the 
settlement terms will be finalized (and, if not completed, 
our liability in connection with this matter may exceed 
$13.0)).  Additionally, remediation of any such findings 
resulting from these and any future investigations could 
have an adverse effect on our business operations, and 
we could experience interruptions of business, harm to 
our reputation, debarment from government contracts, 
loss of supplier, vendor or other third-party relationships, 
licenses  and  permits  could  be 
and  necessary 
terminated. Other internal or government investigations 
or  legal  or  regulatory  proceedings,  including  lawsuits 
brought  by  private  litigants,  may  also  follow  as  a 
consequence.  Cooperating  with  and  responding  to 
requests  for  information  in  connection  with  these 
ongoing  investigations,  as  well  as  responding  to  any 
future U.S., state or foreign governmental investigation 
or  whistleblower  lawsuit,  has  resulted  and  could 
continue to result in substantial expenses, and could 
divert  management’s  attention  from  other  business 
concerns and could have a material adverse effect on 
our  business  and  financial  condition  and  growth 
prospects.

laws  and 

in  healthcare 

Changes 
implementing 
regulations, as well as changes in healthcare policy, may 
affect coverage and reimbursement of our products in 
ways that we cannot currently predict and these changes 
could  adversely  affect  our  business  and  financial 
condition.

 In the U.S., there have been a number of legislative 
and regulatory initiatives focused on containing the cost 
of healthcare. The PPACA substantially changed the way 
healthcare is financed by both governmental and private 
insurers  in  the  U.S.,  and  significantly  impacts  the 
pharmaceutical industry. The PPACA 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,  rules  regarding 
prescription  drug  benefits  under  health  insurance 
exchanges, expansion of the 340B program, expansion 
fraud  and  abuse 
of  state  Medicaid  programs, 
enforcement  and  rules  governing  the  approval  of 
biosimilar products (and allowing biosimilars access to 
the  market  in  accordance  with  the  FDA’s  Biosimilars 
Action  Plan).  These  changes  may  impact  existing 
government healthcare programs and may result in the 
development  of  new  programs,  including  Medicare 
payment for performance initiatives and improvements 
to the physician quality reporting system and feedback 
program.  In  2016,  CMS  implemented  changes  to  the 
Medicaid  Drug  Rebate  Program  under  the  PPACA. 
Moreover, in the future, Congress could enact legislation 
that further increases Medicaid drug rebates or other 
costs and charges associated with participating in the 

50

Medicaid  Drug  Rebate  Program.  The  issuance  of 
regulations  and  coverage  expansion  by  various 
governmental  agencies  relating  to  the  Medicaid  Drug 
Rebate Program has and may continue to increase our 
costs and the complexity of compliance, has been and 
may  be  time-consuming,  and  could  have  a  material 
adverse effect on our results of operations.

  Similar  efforts  to  those  in  the  United  States, 
and in some cases even more aggressive efforts, are 
being  taken  by  governments  to  control  the  costs  of 
pharmaceutical drugs in countries outside the U.S. In 
these  markets  outside  the  U.S.,  the  pricing  and 
reimbursement of pharmaceutical products is subject 
to  direct  or  indirect  governmental  control  and  such 
government  authorities  are  increasingly  attempting  to 
limit or regulate the price of drug products and due to 
their  control  over  pricing  are  able  to  move  quickly  to 
implement pricing changes.

We may face uncertainties as a result of federal 
and administrative efforts to repeal, substantially modify 
or invalidate some or all of the provisions of the PPACA. 
There  is  no  assurance  that  the  PPACA,  as  currently 
enacted or as amended in the future, will not adversely 
affect our business and financial results, and we cannot 
predict  how  future  federal  or  state  legislative  or 
administrative  changes  relating  to  healthcare  reform 
may affect our business.

The  current  presidential  administration  has  also 
indicated an intent to address prescription drug pricing 
and  recent  Congressional  hearings  have  brought 
increased public attention to the costs of prescription 
drugs.  These  actions  and  the  uncertainty  about  the 
future  of  the  PPACA  and  healthcare  laws  may  put 
downward  pressure  on  pharmaceutical  pricing  and 
increase our regulatory burdens and operating costs.

rebates 

  State  governments  have  sought  to  put  in  place 
limits and caps on pharmaceutical prices and have also 
requested 
for  certain  pharmaceuticals. 
Attempts  to  decrease  prices  of  pharmaceuticals 
products may lead to increased use of managed care 
organizations by Medicaid programs which could lead to 
managed  care  organizations  influencing  prescription 
decisions 
for  beneficiaries  and  a  corresponding 
limitation on prices and reimbursement for our products.

Governments in countries where we operate have 
adopted  or  have  also  shown  significant  interest  in 
pursuing  legislative  initiatives  to  reduce  costs  of 
healthcare.  We  expect  that  the  implementation  of 
current laws and policies, the amendment of those laws 
and policies in the future, as well as the adoption of new 
laws and policies, 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. 
The  announcement  or  adoption  of  regulatory  or 
legislative  proposals  could  delay  or  prevent  our  entry 

into new markets, affect our reimbursement or sales in 
the markets where we are already selling our products 
and  materially  harm  our  business,  financial  condition 
and results of operations.

If  we  fail  to  comply  with  our  reporting  and  payment 
obligations under the Medicaid Drug Rebate Program, 
Medicare, or other governmental pricing programs, we 
reimbursement 
could  be  subject 
requirements, penalties, sanctions and fines which could 
have a material adverse effect on our business, financial 
condition, results of operations and prospects.

to  additional 

We participate in and have certain price reporting 
obligations to the Medicaid Drug Rebate Program and 
we have obligations to report the average sales price 
under the Medicare program. Under the Medicaid Drug 
Rebate Program, we are required to pay a rebate to each 
state Medicaid program for quantities of our products 
that are dispensed to Medicaid beneficiaries and paid 
for by a state Medicaid program as a condition of having 
federal funds being made available to the states for our 
products under Medicaid and Medicare Part B. Those 
rebates are based on pricing data reported by us on a 
monthly  and  quarterly  basis  to  CMS.  Any  failure  to 
comply with these price reporting and rebate payment 
obligations could negatively impact our financial results.

Pricing  and  rebate  calculations  vary  among 
products  and  programs.  The  calculations,  including 
those  in  connection  with  the  Medicaid  Drug  Rebate 
Program and 340B drug pricing program (as described 
further  below)  are  complex  and  are  often  subject  to 
interpretation  by  us,  governmental  or  regulatory 
agencies and the courts. We cannot assure you that our 
submissions will not be found by CMS or other applicable 
government authorities to be incomplete or incorrect. 
Governmental  agencies  may  also  make  changes  in 
program interpretations, requirements or conditions of 
participation, some of which may have implications for 
amounts previously estimated or paid. For example, if 
we become aware that our reporting to CMS for a prior 
quarter  was  incorrect,  or  has  changed  as  a  result  of 
recalculation  of  the  pricing  data,  we  are  obligated  to 
resubmit the corrected data for a period not to exceed 
twelve  quarters  from  the  quarter  in  which  the  data 
originally  were  due,  and  CMS  may  request  or  require 
restatements 
for  earlier  periods  as  well.  Such 
restatements and recalculations increase our costs for 
complying with the laws and regulations governing these 
programs, including the Medicaid Drug Rebate Program. 
Any corrections to our rebate calculations could result 
in an overage or underage in our rebate liability for past 
quarters,  depending  on  the  nature  of  the  correction. 
Price recalculations also may affect the ceiling price at 
which we are required to offer our products to certain 
covered entities under the 340B pricing program.

We  are  liable  for  errors  associated  with  our 
submission  of  pricing  data.  In  addition  to  retroactive 
rebates  and  the  potential  for  340B  program  refunds, 

51

civil monetary penalties can be applied if we are found 
to  have  knowingly  submitted  any 
false  pricing 
information to the government, if we are found to have 
made a misrepresentation in the reporting of our average 
sales price, or if we fail to submit the required pricing 
data  on  a  timely  basis.  Such  conduct  also  could  be 
grounds for CMS to terminate our Medicaid drug rebate 
agreement,  pursuant  to  which  we  participate  in  the 
Medicaid program. In the event that CMS terminates our 
rebate  agreement,  federal  payments  may  not  be 
available  under  Medicaid  or  Medicare  Part  B  for  our 
covered outpatient drugs. If a governmental authority, 
such as CMS, were to take any of the foregoing actions, 
our business and results of operations may be negatively 
impacted. 

The Public Health Service’s 340B drug pricing program, 
and  other  comparable  government  and  payer 
regulations, may have a negative impact on the price we 
can charge for our products and result in a decrease in 
revenues.

to  agree 

Federal  law  requires  that  any  company  that 
participates in the Medicaid Drug Rebate Program also 
participate  in  the  Public  Health  Service’s  340B  drug 
pricing program in order for federal funds to be available 
for  the  manufacturer’s  drugs  under  Medicaid  and 
Medicare  Part  B.  The  340B  pricing  program  requires 
participating  manufacturers 
to  charge 
statutorily-defined  covered  entities  no  more  than  the 
340B  “ceiling  price”  for  the  manufacturer’s  covered 
outpatient drugs.  The 340B pricing program is described  
in Pharmaceutical Pricing and Reimbursement in Item 1 
Business in this Annual Report on Form 10-K. The 340B 
ceiling  price  is  calculated  using  a  statutory  formula, 
which  is  based  on,  among  other  prices,  the  average 
manufacturer price and rebate amount for the covered 
outpatient drug as calculated under the Medicaid Drug 
Rebate Program. We are a participant in the 340B drug 
pricing  program  and  are,  for  the  applicable  covered 
entities, subject to the price ceiling. Any changes to the 
340B drug pricing program, including: 

• the method of calculating the 340B ceiling price 
for our products (such as the pricing regulations 
that have been further delayed until July 2019);

• any expansion of the entities that qualify as 

covered entities; and 

• any requirement that participating manufacturers 

agree to provide 340B discounted pricing on 
drugs used in an inpatient settings;

could have a material and negative impact our 
revenue and results of operations.

In  addition,  the  agreement  that  manufacturers 
must  sign  to  participate  in  the  340B  pricing  program 
obligates  a  manufacturer  to  offer  the  340B  price  to 
covered  entities  if  the  manufacturer  makes  the  drug 

available to any other purchaser at any price and to report 
to the government the ceiling prices for its drugs. 

Beyond  the  Public  Health  Service’s  340B  drug 
pricing  program,  federal  law  requires  that  a  company 
must participate in the Department of Veterans Affairs 
Federal  Supply  Schedule  (FFS)  pricing  program  to  be 
eligible to have its products paid for with federal funds. 
If we overcharge the government in connection with our 
FSS contract or Section 703 Agreement, whether due to 
a misstated FCP or otherwise, we are required to refund 
the  difference  to  the  government.  Failure  to  make 
necessary  disclosures  and/or  to  identify  contract 
overcharges can result in allegations against us under 
the  FCA  and  other  laws  and  regulations.  Unexpected 
refunds  to  the  government,  and  responding  to  a 
government investigation or enforcement action, may be 
expensive, and could have a material adverse effect on 
our business, financial condition, results of operations 
and growth prospects. 

We may be subject to numerous and varying privacy and 
security laws, and our failure to comply could result in 
penalties and reputational damage.

We  are  subject  to  laws  and  regulations  covering 
data privacy and the protection of personal information 
including  health  information.  The  legislative  and 
regulatory  landscape  for  privacy  and  data  protection 
continues to evolve, and there has been an increasing 
focus on privacy and data protection issues which may 
affect our business. In the U.S., numerous federal and 
state  laws  and  regulations,  including  state  security 
breach notification laws, state health information privacy 
laws, and federal and state consumer protection laws, 
govern the collection, use, disclosure, and protection of 
personal information. Each of these laws is subject to 
varying  interpretations  by  courts  and  government 
agencies, creating complex compliance issues for us. If 
we fail to comply with applicable laws and regulations 
we could be subject to penalties or sanctions, including 
criminal  penalties  if  we  knowingly  obtain  or  disclose 
individually  identifiable  health  information  from  a 
covered  entity  in  a  manner  that  is  not  authorized  or 
permitted by HIPAA.

Numerous other countries have, or are developing, 
laws governing the collection, use and transmission of 
personal  information  as  well.  EU  Member  States  and 
other  jurisdictions  have  adopted  data  protection  laws 
and  regulations,  which  impose  significant  compliance 
obligations. For example, the EC adopted the EU Data 
Protection Directive, as implemented into national laws 
by  the  EU  Member  States,  which  imposes  strict 
obligations  and  restrictions  on  the  ability  to  collect, 
analyze,  and  transfer  personal  data,  including  health 
data  from  clinical  trials  and  adverse  event  reporting. 
Data protection authorities from different EU Member 
States  have  interpreted  the  privacy  laws  differently, 
which  adds  to  the  complexity  of  processing  personal 
data  in  the  EU,  and  guidance  on  implementation  and 

52

compliance  practices  are  often  updated  or  otherwise 
revised. Any failure to comply with the rules arising from 
the  EU  Data  Protection  Directive  and  related  national 
laws  of  EU  Member  States  could  lead  to  government 
enforcement actions and significant penalties against 
us, and adversely impact our operating results. 

In May 2016, the EU formally adopted the General 
Data  Protection  Regulation,  which  applies  in  all  EU 
Member States and went into effect on May 25, 2018 
and replaced the EU Data Protection Directive on that 
date.  The  regulation  introduces  new  data  protection 
requirements  in  the  EU  and  substantial  fines  for 
breaches of the data protection rules. It increases our 
responsibility and liability in relation to personal data 
that we process and we may be required to put in place 
additional  mechanisms  ensuring  compliance  with  the 
new EU data protection rules. 

Security  breaches,  cyber-attacks  or  other  disruptions 
could expose us to liability and affect our business and 
reputation.

We are increasingly dependent on our information 
technology systems and infrastructure for our business. 
We  collect,  store  and  transmit  sensitive  information 
including  intellectual  property,  proprietary  business 
information and personal information in connection with 
business operations. The secure maintenance of this 
information is critical to our operations and business 
strategy. Some of this information could be an attractive 
target of criminal attack by third parties with a wide range 
of motives and expertise, including organized criminal 
groups,  “hacktivists,”  patient  groups,  disgruntled 
current or former employees and others. Cyber-attacks 
are  of  ever-increasing  levels  of  sophistication,  and 
despite  our  security  measures,  our 
information 
technology and infrastructure may be vulnerable to such 
attacks or may be breached, including due to employee 
error or malfeasance. We have implemented information 
security  measures  to  protect  patients’  personal 
information  against  the  risk  of  inappropriate  and 
unauthorized  external  use  and  disclosure.  However, 
despite these measures, and due to the ever changing 
information cyber-threat landscape, we may be subject 
to data breaches through cyber-attacks. Any such breach 
could  compromise  our  networks  and  the  information 
stored there could be accessed, publicly disclosed, lost 
or stolen. If our systems become compromised, we may 
not  promptly  discover  the 
intrusion.  Like  other 
companies in our industry, we have experienced attacks 
to  our  data  and  systems,  including  malware  and 
computer viruses. If our systems failed or were breached 
or  disrupted,  we  could  lose  product  sales,  and  suffer 
reputational damage and loss of customer confidence. 
Such incidents may result in notification obligations to 
affected  individuals  and  government  agencies,  legal 
claims or proceedings, and liability under foreign, federal 
and state laws that protect the privacy and security of 
personal  information.  Any  one  of  these  events  could 

cause  our  business  to  be  materially  harmed  and  our 
results of operations may be adversely impacted.

Negative  public  opinion  and  increased  regulatory 
scrutiny  of  recombinant  and  transgenic  products, 
genetically modified products and genetically modified 
animals generally may damage public perception of our 
current and future products or adversely affect our ability 
to conduct our business and obtain regulatory approvals 
we may seek.

KANUMA is a transgenic product produced in the 
egg whites of genetically modified chickens who receive 
copies  of  the  human  lysosomal  acid  lipase  gene  to 
produce recombinant human lysosomal acid lipase. The 
success  of  KANUMA  may  depend  in  part  on  public 
attitudes  of  the  use  of  genetic  engineering.  Public 
attitudes may be influenced by claims and perceptions 
that these types of activities or products are unsafe, and 
our products may not gain sufficient acceptance by, or 
fall out of favor with, the public or the medical community. 
Negative  public  attitudes  to  genetic  engineering 
activities  in  general  could  result  in  more  restrictive 
legislation or regulations and could impede our ability 
to  conduct  our  business,  delay  preclinical  or  clinical 
studies, or otherwise prevent us from commercializing 
our product.

Risks Related to Intellectual Property

If we cannot obtain new patents, maintain our existing 
patents and protect the confidentiality and proprietary 
nature  of  our  trade  secrets  and  other  intellectual 
property, our business and competitive position may be 
harmed.

Our success depends in part on our ability to obtain 
and maintain patent and regulatory protections for our 
products  and  investigational  compounds,  to  preserve 
our trade secrets and other proprietary rights, to operate 
without infringing the proprietary rights of third parties 
and  to  prevent  third  parties  from  circumventing  our 
rights.  Due  to  the  time  and  expense  of  bringing  new 
products through development and regulatory approval 
to  the  marketplace,  there  is  particular  importance  in 
obtaining  patent  and  trade  secret  protection  for 
significant new technologies, products and processes.  

We have and may in the future obtain patents or 
the  right  to  practice  patents  through  ownership  or 
license. Our patent applications may not result in the 
issue  of  patents  in  the  U.S.  or  other  countries.  In 
addition, a patent may be issued in one country, but a 
counterpart patent may not be issued in another country. 
For example, we have applied for a certain patent in the 
EU that would provide protection for the composition of 
matter for SOLIRIS through 2027, and while a similar 
patent  was  granted  in  the  U.S.,  the  European  patent 
application remains under examination by the European 
Patent Office and a hearing on it scheduled for February 
2019 has been delayed until later in the year. Even if a 
patent  is  issued,  that  is  not  conclusive  as  to 

53

inventorship,  scope,  validity  or  enforceability  and 
therefore that patent may not afford adequate (or any) 
protection for our products. Third parties may challenge 
our patents, and have challenged our patents in the past 
and,  in  some  cases  have  been  successful  in  such 
challenges.  For  example,  on  January  21,  2019,  the 
Opposition  Division  of  the  European  Patent  Office 
opposition 
following  multi-party 
determined, 
proceedings,  to  revoke  our  European  patent  No. 
2359834, which relates to the formulation of SOLIRIS. 
If any of our patents are narrowed, invalidated, revoked 
or become unenforceable, competitors may develop and 
market products similar to ours that do not conflict with 
or infringe our patents rights, which could have a material 
adverse effect on our financial condition. We may also 
finance  and  collaborate  in  research  conducted  by 
government  organizations,  hospitals,  universities  or 
other  educational  or  research 
institutions.  Such 
research partners may be unwilling to grant us exclusive 
rights to technology or products developed through such 
collaborations. There is also a risk that disputes may 
arise  as  to  the  rights  to  technology  or  products 
developed  in  collaboration  with  other  parties.  Our 
products  and  product  candidates  are  expensive  and 
time-consuming to test and develop. Even if we obtain 
and maintain patents, our business may be significantly 
harmed if the patents are not broad enough to protect 
our products from copycat products.

include 

Significant  legal  questions  exist  concerning  the 
extent  and  scope  of  patent  protection 
for 
biopharmaceutical products and processes in the U.S. 
and  elsewhere.  Accordingly,  there  is  no  certainty  that 
patent applications owned or licensed by us will issue 
as  patents,  or  that  our  issued  patents  will  afford 
meaningful  protection  against  competitors.  Once 
issued, patents are subject to challenge through both 
administrative and judicial proceedings in the U.S. and 
other  countries.  Such  proceedings 
re-
examinations, inter partes reviews, post-grant reviews 
and interference proceedings before the U.S. Patent and 
Trademark  Office,  as  well  as  opposition  proceedings 
before the European Patent Office and other non-U.S. 
patent offices. Certain countries have laws that provide 
stronger bases for challenging third party patent rights 
than  are  available  to  challenge  patents  in  other 
countries.  Therefore,  we  may  be  able  to  defend  our 
patents against a third party claim in one country but 
counterpart  patents  may  be  invalidated  in  other 
countries and we may be able to invalidate a third-party 
patent in one country but not invalidate its counterpart 
patents in other countries. Litigation may be required to 
enforce,  defend  or  obtain  our  patent  and  other 
rights.  Any  administrative 
intellectual  property 
proceeding  or  litigation  could  require  a  significant 
commitment  of  our  resources  and,  depending  on 
outcome, could adversely affect the scope, validity or 
enforceability of certain of our patent or other proprietary 
rights.

In addition, our business requires using sensitive 
technology, techniques and proprietary compounds that 
we protect as trade secrets. However, we may also rely 
heavily on collaboration with, or discuss the potential 
for collaboration with, suppliers, outside scientists and 
other  biopharmaceutical  companies, 
in 
connection with development efforts such as those with 
Complement  Pharma  and  Dicerna.  Collaboration  and 
discussion of potential collaboration present a strong 
risk of exposing our trade secrets. If our trade secrets 
were exposed, we may lose the protection and potential 
exclusive rights afforded by trade secret law, and such 
exposure may likely help our competitors and allow them 
to access technology without restriction and adversely 
affect our business prospects.

including 

If we are found to be infringing third party patents, we 
may be forced to pay damages to the patent owner and/
or obtain a license to continue the manufacture, sale or 
development  of  our  products.  If  we  cannot  obtain  a 
license, we may be prevented from the manufacture, sale 
or development of our products or product candidates, 
which may adversely affect our business.

Parts  of  our  technology,  techniques,  proprietary 
compounds and potential product candidates, including 
those which are or may be in-licensed, may be found to 
infringe patents owned by or granted to others. We have 
and  may  in  the  future  receive  notices  claiming  our 
products infringe third party patents and third parties 
have and may in the future file civil lawsuits against us 
claiming infringement of their intellectual property rights. 
Most recently, in late-2018, Chugai Pharmaceutical Co., 
Ltd.  filed  suits  in  the  U.S.  and  Japan  alleging  that 
ULTOMIRIS infringes a U.S. and two Japanese patents, 
respectively, held by Chugai (these suits are still in the 
early stages). Additional third parties may claim that the 
manufacture,  use  or  sale  of  our  products  or  product 
candidates infringes patents owned or granted to such 
third parties. We are aware of patents owned by third 
parties that might be claimed by such third parties to 
be infringed by the development and commercialization 
of our products or investigational compounds. In respect 
to some of these patents, we have obtained licenses, 
or  expect  to  obtain  licenses.  However,  with  regard  to 
other patents, we have determined in our judgment that:

• our products and investigational compounds do 

not infringe the patents;

• the patents are not valid or enforceable; and/or

• we have identified and are testing various 

alternatives that should not infringe the patents 
and which should permit continued development 
and commercialization of our products and 
investigational compounds.

Any  holder  of  these  patents  or  other  patents 
covering similar technology could sue us for damages 

54

and seek to prevent us from manufacturing, selling or 
developing our products. Intellectual property disputes, 
such as those initiated by Chugai, can be costly and time 
consuming to defend. Prior to launch of a new product 
(or an existing product for a new indication), for various 
reasons, a patent owner may not be able to assert its 
patent rights so it is likely that any potential challenges 
to our products may be made after a product has been 
commercialized  and  not  while  the  product  is  in 
development, in clinical trials or during the regulatory 
review process. If we cannot successfully defend against 
any future actions or conflicts, if they arise, we may incur 
substantial legal costs and may be liable for damages, 
be required to obtain costly licenses or be forced to stop 
manufacturing, using or selling our products, which may 
adversely affect our business. We may seek to obtain a 
license prior to or during legal actions in order to reduce 
the risks in connection with product launches (or at a 
later time) and to reduce further costs and the risk of a 
court  determination  that  our  technology,  techniques, 
proprietary compounds or potential product candidates 
infringe the third party’s patents. A required license may 
be costly or may not be available on acceptable terms, 
if at all. A costly license, or inability to obtain a necessary 
license,  could  have  a  material  adverse  effect  on  our 
business. In addition, even if we obtained a license, it 
would  likely  be  non-exclusive  and  any  competitive 
advantage resulting from the licensed technology may 
be of limited value and the same technology could be 
utilized by competitors.

In some instances, we believe we may prevail in a 
patent infringement action. There can, however, be no 
assurance that the court will agree with our position or 
that they will decide this or any other infringement case 
in  our  favor.  Nor  can  we  be  certain  that,  if  we  do  not 
prevail  in  litigation,  that  we  may  be  able  to  obtain  a 
license  to  any  third-party  patent  on  commercially 
reasonable  terms  or  at  all;  successfully  develop  non-
infringing  alternatives  on  a  timely  basis  (or  at  all);  or 
license  alternative  non-infringing  technology,  if  any 
exists, on commercially reasonable terms (or at all). Any 
impediment  to  our  ability  to  manufacture,  use  or  sell 
approved  forms  of  our  products  or  our  product 
candidates could have a material adverse effect on our 
business and prospects.

It is possible that we could lose market exclusivity for a 
product  earlier  than  expected,  which  may  harm  our 
competitive position.

In  our  industry,  much  of  an  innovative  product’s 
commercial  value  is  realized  while  it  has  market 
exclusivity.  When  market  exclusivity  expires  and 
biosimilar  or  generic  versions  of  the  product  are 
approved  and  marketed,  there  can  be  substantial 
decline in the innovative product’s sales.

Market exclusivity for our products is based upon 
patent rights and certain regulatory forms of protection. 
The scope of our product patent rights vary from country 

to  country  and  is  dependent  on  the  availability  of 
meaningful legal remedies in each country. The failure 
to obtain patent and other intellectual property rights, 
or limitations on the use, or loss of such rights, could 
be material to our business. In some countries, patent 
protections  for  our  products  may  not  exist  because 
certain  countries  did  not  historically  offer  the  right  to 
obtain specific types of patents or we did not file patents 
in  those  markets.  Also,  the  patent  environment  is 
unpredictable  and  the  validity  and  enforceability  of 
patents  cannot  be  predicted  with  certainty.  Absent 
relevant patent protection for a product, once regulatory 
exclusivity periods expire, biosimilar or generic versions 
of the product can be approved and marketed. Even prior 
to the expiration of regulatory exclusivity, a competitor 
could seek to obtain marketing approval by submitting 
its own clinical trial data.

The  market  exclusivity  of  our  products  may  be 
impacted  by  competitive  products  that  are  either 
innovative or biosimilar or generic copies. In our industry, 
the  potential  for  biosimilar  challenges  has  been  an 
increasing risk to product market exclusivity. U.S. law 
includes an approval pathway for biosimilar versions of 
innovative biological products. Under the pathway, the 
FDA may approve products that are similar to (but not 
generic copies of) innovative biologics on the basis of 
less extensive data than is required for a full biologic 
license application. After an innovator has marketed its 
product for four years, other manufacturers may apply 
for  approval  of  a  biosimilar  version  of  the  innovator 
product.  However,  qualified 
innovative  biological 
products  will  receive  12  years  of  regulatory  market 
exclusivity  (i.e.,  the  biosimilar  product  cannot  be 
approved before 12 years after the innovative biological 
product).  The  law  also  provides  a  mechanism  for 
innovators  to  enforce  their  patents  that  protect  their 
products and for biosimilar applicants to challenge the 
patents. Such litigation may begin as early as four years 
after the innovative biological product is first approved 
by the FDA. Pathways for biosimilar products also exist 
in  many  other  markets,  including  Europe,  Japan  and 
Russia. Other companies are developing and advancing 
SOLIRIS  biosimilar  programs,  including  conducting 
clinical  trials.  Competition,  including  from  biosimilars 
approved for marketing, may likely result in a decrease 
in prices, increased promotion efforts and lower margins 
for  our  products.  In  addition,  approval  of  a  biosimilar 
that is substitutable for one of our products may increase 
the  risk  of  accelerated  market  penetration  by  that 
biosimilar. Further, if patients or healthcare providers do 
not believe that ULTOMIRIS provides a compelling profile 
for  patient  conversion  from  SOLIRIS,  a  SOLIRIS 
biosimilar may not only be expected to have a material 
and  negative  impact  on  our  SOLIRIS  revenues  and 
margins (which accounted for a significant percentage 
of  our  revenue  in  2018),  it  may  also  have  a  material 
impact  on  ULTOMIRIS  revenue  and  margins  and  the 
ability of ULTOMIRIS to gain market acceptance.

Our other products are also at risk from biosimilars. 
Other  than  SOLIRIS  for  the  treatment  of  gMG  and 
SOLIRIS and ULTOMIRIS as a treatment for PNH, each 
of our products is currently the only approved drug for 
the  disease(s)  the  product  treats.  If  a  competitive 
product is approved for sale, including a biosimilar or 
generic  product,  our  market  share  and  our  revenues 
could decline, particularly if the competitive product is 
perceived to be more effective or is less expensive than 
our product.

Risks Related to Our Common Stock

Our stock price is volatile.

The trading price of our common stock has been 
volatile and may continue to be volatile in the future. 
Many factors could have an impact on our stock price, 
including  fluctuations  in  our  or  our  competitors’ 
operating results, clinical trial results or adverse events 
associated with our products, product development by 
us  or  our  competitors,  changes  in  laws,  including 
healthcare, tax or intellectual property laws, intellectual 
property developments, changes in reimbursement or 
drug pricing, the existence or outcome of litigation or 
the  SEC/DOJ 
government  proceedings, 
investigation  and  the  Chugai  lawsuits  alleging  patent 
infringement, 
strategic 
transactions, and the perceptions of our investors that 
we  are  not  performing  or  meeting  expectations.  The 
trading  price  of 
the  common  stock  of  many 
biopharmaceutical  companies,  including  ours,  has 
experienced price and volume fluctuations, which have 
at times been unrelated to the operating performance 
of the companies whose stocks were affected.

acquisitions 

including 

other 

or 

Anti-takeover provisions in our charter and bylaws and 
under Delaware law could make a third-party acquisition 
of us difficult and may frustrate any attempt to remove 
or replace our current management.

Our  corporate  charter  and  by-law  provisions  may 
discourage  certain  types  of  transactions  involving  an 
actual  or  potential  change  of  control  that  might  be 
beneficial to us or our stockholders. Our bylaws provide 
that special meetings of our stockholders may be called 
only  by  the  Chairman  of  the  Board  of  Directors,  the 
President, the Secretary, or a majority of the Board of 
Directors, or upon the written request of stockholders 
who together own of record 25.0% of the outstanding 
stock of all classes entitled to vote at such meeting. 
Our bylaws also specify that the authorized number of 
directors may be changed only by resolution of the Board 
of Directors. Our charter does not include a provision 
for  cumulative  voting  for  directors,  which  may  have 
enabled  a  minority  stockholder  holding  a  sufficient 
percentage of a class of shares to elect one or more 
directors. Under our charter, our Board of Directors has 
the authority, without further action by stockholders, to 
designate up to five million shares of preferred stock in 
one or more series. The rights of the holders of common 

55

stock will be subject to, and may be adversely affected 
by,  the  rights  of  the  holders  of  any  class  or  series  of 
preferred stock that may be issued in the future.
Because we are a Delaware corporation, the anti-
takeover provisions of Delaware law could make it 
more difficult for a third party to acquire control of us, 
even if the change in control may be beneficial to 
stockholders. We are subject to the provisions of 
Section 203 of the Delaware General Laws, which 
prohibits a person who owns in excess of 15.0% of 
our outstanding voting stock from merging or 
combining with us for a period of three years after the 
date of the transaction in which the person acquired 
in excess of 15.0% of our outstanding voting stock, 
unless the merger or combination is approved in a 
prescribed manner.

We believe that our administrative office space is adequate to meet our needs for the foreseeable future. We also 
believe  that  our  research  and  development  facilities  and  our  manufacturing  facilities,  together  with  third  party 
manufacturing facilities, will be adequate for our on-going activities. In addition to the locations above, we also lease 
space in other U.S. locations and in foreign countries to support our operations as a global organization.

In April 2014, we purchased a fill/finish facility in Athlone, Ireland, which has been refurbished to become our 
first company-owned fill/finish facility. In July 2016, we announced plans to construct a new biologics manufacturing 
facility at this site, the construction of this facility is on-going and, based on current expectations, we anticipate this 
facility will receive regulatory approval in 2020.

In May 2015, we announced plans to construct a new biologics manufacturing facility on our existing property in 
Dublin, Ireland, the construction of this facility has commenced and, based on current expectations, we anticipate this 
facility will receive regulatory approval in 2020.

In the fourth quarter of 2018, we amended the New Haven lease agreement significantly reducing our rented 

square footage in the building beginning in 2019 through the expiration of the lease.

In addition to the following notes, see “Management’s Discussion and Analysis of Financial Condition and Results 
of Operations” and the Consolidated Financial Statements and accompanying notes and previously filed Annual Reports 
on Form 10-K for further information regarding our consolidated results of operations and financial position for periods 
reported therein.

(1) In March 2014, we entered into an agreement with the French government which positively impacted prospective 
reimbursement of SOLIRIS and also provided for reimbursement for shipments made in years prior to January 1, 
2014. As a result of the agreement, in 2014 we recognized $87.8 of net product sales from SOLIRIS in France relating 
to years prior to January 1, 2014.

(2) In 2017, we committed to an operational plan to re-align the global organization with its refocused corporate strategy. 
As a result of this re-alignment, in 2017, we recorded additional asset related charges of $152.1 associated with 
the planned closure of the ARIMF facility to cost of sales (which facility was subsequently sold in 2018). These charges 
primarily relate to accelerated depreciation and the impairment of manufacturing assets. Additionally, the re-alignment 
in 2017 resulted in restructuring expenses of $104.6, primarily related to employee separation costs.

(3) In the second quarter 2018, we completed the acquisition of Wilson Therapeutics AB (publ). We acquired in-process 
research and development related to WTX101, an early Phase III asset in development for the treatment of Wilson 
Disease. Due to the stage of development of this asset, the value of this asset of $803.7 was expensed during 2018. 
In the fourth quarter of 2018 we completed the acquisition of Syntimmune, Inc. We acquired in-process research and 
development  related  to  SYNT001,  which  is  in  Phase  1b/2a  trials  and  in  development  for  the  treatment  of 
Immunoglobulin G and IgG-mediated autoimmune diseases. Due to the stage of development of this asset, the value 
of this asset of $379.3 was expensed during 2018.

(4) In the third quarter 2015, we received regulatory approval for STRENSIQ and KANUMA. As a result, we began amortizing 

intangible assets associated with STRENSIQ and KANUMA. 

(5) We recognized an unrealized gain of $44.4 on our Moderna Therapeutics equity investment in 2018. Additionally, in 

2016, we incurred a full year of interest expense on our credit facility entered into in 2015.

(6) We recognized tax (benefit) expense of $(56.5) and $45.8 in 2018 and 2017, respectively, as a result of the Tax 
Cuts and Jobs Act. In 2017, we recorded certain impacts of the Tax Act on a provisional basis. As of December 22, 
2018, our accounting for the impact of the Tax Act was complete. See Note 12, “Income Taxes” for additional information.
(7) In 2016, we recognized deferred tax expense of $119.3 associated with the distribution of earnings from our captive 

foreign partnership.

(8) In connection with the integration of the Synageva business with and into the Alexion business, we incurred a one-
time tax expense of $315.6 in the third quarter 2015. This tax expense is attributable to the change in our deferred 
tax liability for the outside basis difference resulting from the movement of assets into our captive foreign partnership. 
(9)  In 2015, in connection with the acquisition of Synageva, we acquired $4,236.0 of intangible assets and $4,783.4

of goodwill.

(10) In 2015, in connection with the acquisition of Synageva, we borrowed $3,500.0 under our term loan under a credit 

facility.  This credit facility was amended and restated in June 2018.

with  the  potential  for  additional  milestone-dependent 
payments  of  up  to $800.0,  for  a  total  value  of  up 
to $1,200.0. 

In December 2018 ULTOMIRIS™ was approved by 
the FDA as a new treatment option for adult patients 
living with paroxysmal nocturnal hemoglobinuria (PNH). 
ULTOMIRIS is the first and only long-acting C5 inhibitor 
that  provides  immediate  and  complete  inhibition  for 
eight weeks. 

In January 2019, we submitted our filings to the 
FDA and the EU for marketing clearance for SOLIRIS as 
a potential treatment of NMOSD.

On January 21, 2019, the Opposition Division of 
the European Patent Office determined, following multi-
party opposition proceedings, to revoke our European 
patent No. 2359834, which relates to the formulation 
of  SOLIRIS.  Subject  to  our  review  of  the  final  written 
decision  of  the  European  Patent  Office,  we  currently 
expect  that  we  will  appeal  this  decision.   While  any 
appeal  is  pending  at  the  European  Patent  Office,  the 
claims in the originally granted patent remain in force.

In January 2019, we announced the results of the 
Phase III study with ULTOMIRIS (ALXN1210) meeting its 
primary objective in complement inhibitor-naïve patients 
with aHUS. In the initial 26 week treatment period in 
this  study,  53.6  percent  of  patients  demonstrated 
complete thrombotic microangiopathy (TMA) response.

In January 2019, we entered into a collaboration 
agreement  with  Caelum  Biosciences  (Caelum)  to 
develop CAEL101 for light chain (AL) amyloidosis.  Under 
the  terms  of  the  agreement,  we  acquired  a  minority 
equity  interest  in  Caelum  and  an  exclusive  option  to 
acquire the remaining equity in the company based on 
Phase II data, for pre-negotiated economics. We made 
an upfront payment of $30.0 and could be required to 
pay up to an additional $30.0 in contingent milestone-
dependent option fees. The collaboration also provides 
for potential additional payments, in the event Alexion 
exercises the acquisition option, for up to $500.0, which 
includes  an  upfront  option  exercise  payment  and 
potential 
regulatory  and  commercial  milestone 
payments.

In  addition  to  historical  information,  this  report 
contains  forward-looking  statements  that  involve  risks 
and uncertainties which may cause our actual results to 
differ  materially  from  plans  and  results  discussed  in 
forward-looking statements. We encourage you to review 
the  risks  and  uncertainties,  discussed  in  the  section 
entitled item 1A “Risk Factors”, and the “Note Regarding 
Forward-Looking Statements”, included at the beginning 
of  this  Annual  Report  on  Form  10-K.  The  risks  and 
uncertainties  can  cause  actual  results  to  differ 
significantly  from  those  forecast  in  forward-looking 
statements or implied in historical results and trends.

The  following  discussion  should  be  read  in 
conjunction with our consolidated financial statements 
and  related  notes  appearing  elsewhere  in  this  Annual 
Report on Form 10-K.

Recent Developments 

In  the  fourth  quarter  2018,  we  completed  the 
acquisition of Syntimmune, Inc. (Syntimmune), a clinical-
stage  biotechnology  company  developing  an  antibody 
therapy targeting the neonatal Fc receptor (FcRn). The 
lead  candidate  from  this  acquisition,  ALXN1830 
(SYNT001), is a monoclonal antibody that inhibits the 
interaction of FcRn with Immunoglobulin G (IgG) and IgG 
immune complexes, and is being studied in Phase 1b/
2a trials for the treatment of IgG-mediated autoimmune 
diseases. Under the terms of the agreement, Alexion

Critical Accounting Policies and the Use of Estimates

The  significant  accounting  policies  and  basis  of 
preparation of our consolidated financial statements are 
described in Note 1, “Business Overview and Summary 
of Significant Accounting Policies” of the Consolidated 
Financial Statements included in this Annual Report on 
Form  10-K.  Under  accounting  principles  generally 
accepted in the U.S., we are required to make estimates, 
judgments  and  assumptions  that  affect  the  reported 
amounts of assets, liabilities, revenues, expenses and 
disclosure  of  contingent  assets  and  liabilities  in  our 
financial  statements.  Actual  results  could  differ  from 
those estimates and such differences may be material.

the 

We  believe 

judgments,  estimates  and 
assumptions  associated  with  the  following  critical 
accounting policies have the greatest potential impact 
on our consolidated financial statements:

• Revenue recognition;

• Contingent liabilities;

• Inventories;

• Share-based compensation;

• Valuation of goodwill, acquired intangible assets and 

in-process research and development (IPR&D);

• Valuation of contingent consideration; and

• Income taxes.

Revenue Recognition

In May 2014, the Financial Accounting Standards 
Board  (FASB)  issued  a  comprehensive  new  standard 
which  amends  revenue  recognition  principles.  We 
adopted  the  new  standard  on  January  1,  2018  by 
applying  the  modified  retrospective  method  to  all 
contracts  that  were  not  completed  as  of  that  date. 
 Under the new guidance, revenue is recognized when 
a  customer  obtains  control  of  promised  goods  or 
services, in an amount that reflects the consideration 
expected to be received in exchange for those goods or 
services. Revenue  is  recognized  through  a  five-step 
process: (i) identify the contract(s) with a customer; (ii) 
identify the performance obligations in the contract; (iii) 
determine  the  transaction  price;  (iv)  allocate  the 
transaction price to the performance obligations in the 
contract;  and  (v)  recognize  revenue  when  (or  as)  a 
performance obligation is satisfied. The Company only 
applies  the  five-step  model  to  contracts  when  it  is 
probable that the Company will collect the consideration 
it is entitled to in exchange for the goods or services it 
transfers  to  the  customer. At  contract  inception,  the 
Company  assesses  the  goods  or  services  promised 
within  each  contract,  and  determines  those  that  are 
performance obligations. Revenue is recognized for the 
applicable  performance  element  when  each  distinct 
performance obligation is satisfied. 

While results for reporting periods beginning after 
January 1, 2018 are presented under the new guidance, 

63

prior period amounts are not adjusted and continue to 
be reported under the accounting standards in effect 
for the prior period. The accounting policy for revenue 
recognition  for  periods  prior  to  January  1,  2018  is 
described in Note 1 of the Notes to the Consolidated 
Financial Statements included in our Annual Report on 
Form 10-K for the year ended December 31, 2017.

Nature of Products

Our principal source of revenue is product sales. 
Our contracts with customers generally contain a single 
performance obligation and we recognize revenue from 
product sales when we have satisfied our performance 
obligation by transferring control of the product to our 
customers. Control of the product generally transfers to 
the customer upon delivery. In certain countries, we sell 
to  distributors  on  a  consignment  basis  and  record 
revenue  when  control  of  the  product  transfers  to  the 
customer upon sale to the end user.

Our  customers  are  primarily  comprised  of 
distributors,  pharmacies,  hospitals,  hospital  buying 
groups, and other healthcare providers. In some cases, 
we  may  also  sell  to  governments  and  government 
agencies.  In  addition  to  sales  in  countries  where  our 
products  are  commercially  available,  we  have  also 
recorded  revenue  on  sales  for  patients  receiving 
treatment 
through  named-patient  programs.  The 
relevant  authorities  or  institutions  in  those  countries 
have agreed to reimburse for product sold on a named-
patient basis where our products have not received final 
approval for commercial sale.

remitted 

Revenue is recognized at the amount to which we 
expect  to  be  entitled  in  exchange  for  the  sale  of  our 
products. This amount includes both fixed and variable 
consideration and excludes amounts that are collected 
to  governmental 
from  customers  and 
authorities,  such  as  value-added  taxes  in  foreign 
jurisdictions.  Shipping  and  handling  costs  associated 
with  outbound  freight  after  control  of  a  product  has 
transferred  to  our  customers  are  accounted  for  as  a 
fulfillment cost and are included in operating expenses. 
The  cost  for  any  shipping  and  handling  activities 
(including customs clearance activities) associated with 
transactions for which revenue has been recognized are 
accrued if not completed before the respective period 
end. 

The timing between the recognition of revenue for 
product  sales  and  the  receipt  of  payment  is  not 
significant. Our standard credit terms, which vary based 
on the country of sale, generally range from 30 to 120 
days and all arrangements generally are payable within 
one year of the transfer of the product. We do not assess 
financing 
whether  a  contract  has  a  significant 
component  if  the  expectation  at  contract  inception  is 
such  that  the  period  between  the  transfer  of  the 
promised good to the customer and receipt of payment 
will be one year or less.

income  when 

We evaluate the creditworthiness of customers on 
a regular basis. The length of time from sale to receipt 
of  payment  in  certain  countries  exceeds  our  credit 
terms. In countries in which collections from customers 
extend beyond normal payment terms, we seek to collect 
interest. We record interest on customer receivables as 
interest 
collected.  Subsequent 
adjustments  for  further  declines  in  credit  rating  are 
recorded  as  bad  debt  expense  as  a  component  of 
selling,  general  and  administrative  expense.  We  also 
use judgments as to our ability to collect outstanding 
receivables and provide allowances for the portion of 
receivables  if  and  when  collection  becomes  doubtful, 
and  we  also  assess  on  an  ongoing  basis  whether 
collectibility  is  probable  at  the  time  of  sale.  As  of 
December 31,  2018  and  December 31,  2017, 
allowances on receivables were not material.

Variable Consideration

We  pay  distribution  fees  to  our  distributors  and 
offer  rebates  and/or  discounts,  or  enter  into  volume-
based  reimbursement  arrangements  with  certain 
customers. We reduce the transaction price on our sales 
for these amounts. For variable amounts, we estimate 
the amount of consideration to which we expect to be 
entitled  based  on  all  available  historic,  current  and 
forecast  information.  We  primarily  use  the  expected 
value  method  to  estimate  variable  payments  and,  in 
limited circumstances, will apply the most likely method 
based on the type of variable consideration and what 
method better predicts the amount of consideration we 
expect to be entitled to. Consideration that is received 
from a customer that we expect will need to be refunded 
in  the  future  is  recorded  as  a  refund  liability  to  the 
customer within accrued expenses. Actual amounts of 
consideration ultimately received or refunded may differ 
from  our  estimates,  and  such  difference  may  be 
material.  If  actual  results  in  the  future  vary  from  our 
estimates,  we  adjust  these  estimates,  which  would 
affect net product sales and earnings in the period such 
variances become known, and such variances may be 
material.

Variability in the transaction price for our products 
pursuant  to  our  contracts  with  customers  primarily 
arises from the following:

Discounts  and  Rebates:  We  offer  discounts  and 
rebates to certain distributors and customers under our 
arrangements. In many cases, these amounts are fixed 
at the time of sale and the transaction price is reduced 
accordingly. We also provide for rebates under certain 
governmental programs, including Medicaid in the U.S. 
and other programs outside the U.S., which are payable 
based on actual claim data. We estimate these rebates 
based on an analysis of historical claim patterns and 
estimates of customer mix to determine which sales will 
be subject to rebates and the amount of such rebates. 
We update our estimates and assumptions each period 
and record any necessary adjustments, which may have 

an  impact  on  revenue  in  the  period  in  which  the 
adjustment is made (and such impact may be material). 
Generally, the length of time between product sale and 
the processing and reporting of the rebates is three to 
six months.

Volume-Based Arrangements: We have entered into 
volume-based  arrangements  with  governments  in 
certain  countries  and  other  customers  in  which 
reimbursement  is  limited  to  a  contractual  amount. 
Under  this  type  of  arrangement,  amounts  billed  in 
excess  of  the  contractual  limitation  are  repaid  to  the 
customer  as  a  rebate.  We  estimate  incremental 
discounts resulting from these contractual limitations, 
based on forecasted sales during the limitation period, 
and  we  apply  the  discount  percentage  to  product 
shipments as a reduction of revenue. Our calculations 
related  to  these  arrangements  require  estimation  of 
sales during the limitation period, and adjustments in 
these  estimates  may  have  a  material  impact  in  the 
period in which these estimates change.

We  have  provided  balances  and  activity  in  the

Current provisions relating to sales in the current 
year increased by $41.6 in 2018 compared to 2017 and 
$79.2 in 2017 compared to 2016. The increase in 2018 
was primarily due to increased unit volumes in the U.S. 
which were subject to rebates as well as increases in 
rebate rates in the U.S. on certain product sales. The 
increase  in  2017  was  attributable  to  increased  unit 
volumes in the U.S. and Europe, which were subject to 
rebates, as well as to increases in rebate rates in certain 
geographical regions and on certain product sales as 
compared to the prior year.

Distribution & Other Fees: We pay distribution and 
other fees to certain customers in connection with the 
sales of our products. We record distribution and other 

64

 
fees paid to our customers as a reduction of revenue, 
unless the payment is for a distinct good or service from 
the customer and we can reasonably estimate the fair 
value  of  the  goods  or  services  received.  If  both 
conditions are met, we record the consideration paid to 
the customer as an operating expense. These costs are 
typically known at the time of sale, resulting in minimal 
adjustments subsequent to the period of sale. 

Product  Returns:  Our  contracts  with  customers 
generally  provide  for  returns  only  if  the  product  is 
damaged  or  defective  upon  delivery.  We  assess  our 
sales transactions and arrangements with customers 
and  monitor  inventory  within  our  sales  channels  to 
determine whether a provision for returns is warranted 
and a resulting adjustment to the transaction price is 
necessary.  This  assessment  is  based  on  historical 
experience and assumptions as of the date of sale and 
changes in these estimates could have an impact in the 
period in which the change occurs (and such impact may 
be material). Because of factors such as the price of 
our products, the limited number of patients, the short 
period from product sale to patient infusion and limited 
contractual  return  rights,  our  customers  often  carry 
limited inventory.

The amount of variable consideration included in 
the transaction price is constrained by the amount that 
is  probable  will  not  result  in  a  significant  reversal  of 
revenue.  We  consider  our  experience  with  similar 
transactions and expectations regarding the contract in 
estimating the amount of variable consideration to which 
we expect to be entitled, and determining whether the 
be 
estimated 
constrained. We do not have any material constraints 
on  the  variable  consideration  included  within  the 
transaction price of our current revenue arrangements.

We  continue  to  monitor  economic  conditions, 
including  volatility  associated  with 
international 
economies and the associated impacts on the financial 
markets  and  our  business.  For  additional  information 
related  to  our  concentration  of  credit  risk  associated 
with certain international accounts receivable balances, 
refer  to  the  “Financial  Condition,  Liquidity  and  Capital 
Resources” and “Quantitative and Qualitative Disclosures 
About Market Risk” sections below.  

Contingent liabilities

We  are  currently  involved  in  various  claims  and 
legal proceedings. On a quarterly basis, we review the 
status  of  each  significant  matter  and  assess  its 
potential financial exposure. If the potential loss from 
any claim, asserted or unasserted, or legal proceeding 
is  considered  probable  and  the  amount  can  be 
reasonably  estimated,  we  accrue  a  liability  for  the 
estimated  loss.  Because  of  uncertainties  related  to 
claims  and  litigation,  accruals  are  based  on  our  best 
estimates based on available information. On a periodic 
basis, as additional information becomes available, or 
based  on  specific  events  such  as  the  outcome  of 
litigation  or  settlement  of  claims  (and  our  offers  of 
settlement),  we  may  reassess  the  potential  liability 
related  to  these  matters  and  may  revise  these 
estimates, which could result in a material adjustment 
to our operating results and liquidity.

Inventories

Inventories are stated at the lower of cost or net 
realizable value. Cost is determined in a manner that 
approximates average costs.

We capitalize inventory produced for commercial 
sale,  which  may  include  costs  incurred  for  certain 
products  awaiting  regulatory  approval.  We  capitalize 
inventory produced in preparation of product launches 
sufficient to support estimated initial market demand. 
Capitalization of such inventory begins when we have (i) 
obtained positive results in clinical trials that we believe 
are  necessary  to  support  regulatory  approval,  (ii) 
concluded  that  uncertainties  regarding  regulatory 
approval  have  been  sufficiently  reduced,  and  (iii) 
determined  that  the  inventory  has  probable  future 
economic  benefit. 
these 
conditions  have  been  met,  we  consider  clinical  trial 
results  for  the  underlying  product  candidate,  results 
from  meetings  with  regulatory  authorities,  and  the 
compilation of the regulatory application. If we are aware 
of  any  material  risks  or  contingencies  outside  of  the 
standard regulatory review and approval process, or if 
there are any specific negative issues identified relating 
to  the  safety,  efficacy,  manufacturing,  marketing  or 
labeling  of  the  product  that  would  have  a  significant 
negative  impact  on  its  future  economic  benefits,  the 
related inventory would not be capitalized.

In  evaluating  whether 

Products that have been approved by the FDA or 
other  regulatory  authorities  are  also  used  in  clinical 
programs  to  assess  the  safety  and  efficacy  of  the 
products  for  usage  in  diseases  that  have  not  been 
approved by the FDA or other regulatory authorities. The 
form of product utilized for both commercial and clinical 
programs is identical and, as a result, the inventory has 
an “alternative future use” as defined in authoritative 
guidance. Raw materials and purchased drug product 
associated  with  clinical  development  programs  are 
included  in  inventory  and  charged  to  research  and 
development  expense  when  the  product  enters  the 

65

research and development process and no longer can 
be used for commercial purposes and, therefore, does 
not have an “alternative future use”.

For  products  which  are  under  development  and 
have not yet been approved by regulatory authorities, 
purchased  drug  product  is  charged  to  research  and 
development  expense  upon  delivery.  Delivery  occurs 
when  the  inventory  passes  quality  inspection  and 
ownership  transfers  to  us.  Nonrefundable  advance 
payments  for  research  and  development  activities, 
including  production  of  purchased  drug  product,  are 
deferred and capitalized until the goods are delivered. 
We also recognize expense for raw materials purchased 
for  developmental  purposes  when  the  raw  materials 
pass quality inspection, and we have an obligation to 
pay for the materials.

We analyze our inventory levels to identify inventory 
that may expire prior to sale, inventory that has a cost 
basis  in  excess  of  its  estimated  realizable  value,  or 
inventory  in  excess  of  expected  sales  requirements. 
Although the manufacturing of our product is subject to 
strict quality control, certain batches or units of product 
may no longer meet quality specifications or may expire, 
which would require adjustments to our inventory values. 
We also apply judgment related to the results of quality 
tests  that  we  perform  throughout  the  production 
process,  as  well  as  our  understanding  of  regulatory 
guidelines, to determine if it is probable that inventory 
will  be  saleable.  These  quality  tests  are  performed 
throughout the pre- and post-production process, and 
we  continually  gather  information  regarding  product 
quality  for  periods  after  the  manufacturing  date.  Our 
products currently have a maximum estimated life range 
of 36 to 48 months and, based on our sales forecasts, 
we expect to realize the carrying value of the product 
inventory. In the future, reduced demand, quality issues 
or  excess  supply  beyond 
those  anticipated  by 
management  may  result  in  a  material  adjustment  to 
inventory levels, which would be recorded as an increase 
to cost of sales.

The  determination  of  whether  or  not  inventory 
costs  will  be  realizable  requires  estimates  by  our 
management.  A  critical  input  in  this  determination  is 
future  expected  inventory  requirements  based  on 
internal  sales  forecasts.  We  then  compare  these 
requirements to the expiry dates of inventory on hand. 
For  inventories  that  are  capitalized  in  preparation  of 
product launch, we also consider the expected approval 
date  in  assessing  realizability.  To  the  extent  that 
inventory is expected to expire prior to being sold, we 
will write down the value of inventory. If actual results 
differ from those estimates, additional inventory write-
offs  may  be  required,  and  such  write-offs  may  be 
material.

Share-Based Compensation

We  have  two  share-based  compensation  plans 
pursuant to which awards are currently being made: (i) 

the 2017 Incentive Plan (2017 Plan) and (ii) the 2015 
Employee Stock Purchase Plan (ESPP). The 2017 Plan 
replaced the Amended & Restated 2004 Incentive Plan, 
effective May 10, 2017. Under the 2017 Plan, restricted 
stock, restricted stock units, stock options and  other 
stock-related awards may be granted to our directors, 
officers, employees and consultants or advisors of the 
Company  or  any  subsidiary.  Under  the  ESPP,  eligible 
employees can purchase shares of common stock at a 
discount semi-annually through payroll deductions. To 
date, share-based compensation issued under the plans 
consists of incentive and non-qualified stock options, 
restricted  stock  and  restricted  stock  units,  including 
restricted  stock  units  with  market  and  non-market 
performance conditions, and shares issued under our 
ESPP. 

Compensation  expense  for  our  share-based 
awards is recognized based on the estimated fair value 
of the awards on the grant date. Compensation expense 
reflects an estimate of the number of awards expected 
to  vest  and  is  primarily  recognized  on  a  straight-line 
basis over the requisite service period of the individual 
grants,  which  typically  equals  the  vesting  period. 
Compensation  expense  for  awards  with  performance 
conditions  is  recognized  using  the  graded-vesting 
method. 

Our  estimates  of  employee  stock  option  values 
rely  on  estimates  of  factors  we  input  into  the  Black-
Scholes model. The key factors involve an estimate of 
future  uncertain  events.  Significant  assumptions 
include the use of historical volatility to determine the 
expected  stock  price  volatility.  We  also  estimate 
expected term until exercise and the reduction in the 
expense  from  expected  forfeitures.  We  currently  use 
historical exercise and cancellation patterns as our best 
estimate of future estimated life. Actual volatility and 
lives of options may be significantly different from our 
estimates.

period as necessary. We use payout simulation models 
to  estimate  the  grant  date  fair  value  of  market 
performance-based  awards.  The  payout  simulation 
models assume volatility of our common stock and the

day of an offering period or (ii) the market value per share

of  the  common  stock  on  the  purchase  date.  The  fair 
value of the discounted purchases made under our ESPP 
is  calculated  using  the  Black-Scholes  model.  The  fair 
value of the look-back provision plus the 15% discount 
is  recognized  as  compensation  expense  over  the  6 
month purchase period.

If 

factors  change  or  we  employ  different 
assumptions  to  value  our  stock-based  awards,  the 
share-based compensation expense that we record in 
future  periods  may  differ  materially  from  our  prior 
recorded amounts.

Valuation of Goodwill, Acquired Intangible Assets and In-
Process Research and Development (IPR&D)

IPR&D 

related 

We  have  recorded  goodwill,  acquired  intangible 
to  our  business 
assets  and 
combinations.  When  identifiable  intangible  assets, 
including  IPR&D,  are  acquired,  we  determine  the  fair 
values  of  the  assets  as  of  the  acquisition  date. 
Discounted cash flow models are typically used in these 
valuations if quoted market prices are not available, and 
the models require the use of significant estimates and 
assumptions including but not limited to: 

• 

• 

timing  and  costs  to  complete  the  in-process 
projects;
timing  and  probability  of  success  of  clinical 
events or regulatory approvals;

•  estimated future cash flows from product sales 
resulting  from  completed  products  and  in-
process projects; and

•  discount rates.

We  may  also  utilize  a  cost  approach,  which 
estimates the costs that would be incurred to replace 
the assets being purchased. Significant inputs into the 
cost  approach  include  estimated  rates  of  return  on 
historical costs that a market participant would expect 
to pay for these assets.

Intangible  assets  with  definite  useful  lives  are 
amortized to their estimated residual values over their 
estimated useful lives and reviewed for impairment if 
certain events occur.

the  associated 

Intangible  assets  related  to  IPR&D  projects  are 
considered to be indefinite-lived until the completion or 
abandonment  of 
research  and 
development efforts. During the period the assets are 
considered  indefinite-lived,  they  will  not  be  amortized 
but will be tested for impairment. Impairment testing is 
performed at least annually or when a triggering event 
occurs that could indicate a potential impairment. If and 
when development is complete, which generally occurs 
when  regulatory  approval  to  market  a  product  is 
obtained, the associated assets are deemed finite-lived 
and are amortized over a period that best reflects the 
economic benefits provided by these assets. 

67

If  projects  are  not  successfully  developed,  our 
sales  and  profitability  may  be  adversely  affected  in 
future  periods.  Additionally,  the  value  of  the  acquired 
intangible  assets,  including  IPR&D,  may  become 
impaired if the underlying projects do not progress as 
we initially estimated. We believe that the assumptions 
used  in  developing  our  estimates  of  intangible  asset 
values were reasonable at the time of the respective 
acquisitions. However, the underlying assumptions used 
to estimate expected project sales, development costs, 
profitability, or the events associated with such projects, 
such as clinical results, may not occur as we estimated 
at the acquisition date.

Goodwill represents the excess of purchase price 
over  fair  value  of  net  assets  acquired  in  a  business 
combination and is not amortized. Goodwill is subject 
to  impairment  testing  at  least  annually  or  when  a 
triggering event occurs that could indicate a potential 
impairment. We are organized and operate as a single 
reporting unit and therefore the goodwill impairment test 
is  performed  using  our  overall  market  value,  as 
determined by our traded share price, compared to our 
book value of net assets. 

Valuation of Contingent Consideration

We record contingent consideration resulting from 
a  business  combination  at  its  fair  value  on  the 
acquisition  date.  We  determine  the  fair  value  of  the 
contingent  consideration  based  primarily  on  the 
following factors:

•  timing  and  probability  of  success  of  clinical 

events or regulatory approvals;

•  timing  and  probability  of  success  of  meeting 
commercial  milestones,  such  as  estimated 
future sales levels of a specific compound; and

•  discount rates.

to  operating  earnings.  Changes 

Our  contingent  consideration  liabilities  arose  in 
connection  with  our  business  combinations.  On  a 
quarterly basis, we revalue these obligations and record 
increases  or  decreases  in  their  fair  value  as  an 
adjustment 
to 
contingent  consideration  obligations  can  result  from 
adjustments to discount rates, accretion of the discount 
rates  due  to  the  passage  of  time,  changes  in  our 
estimates  of  the  likelihood  or  timing  of  achieving 
development or commercial milestones, changes in the 
probability of certain clinical events or changes in the 
regulatory 
assumed  probability  associated  with 
approval. 

The assumptions related to determining the value 
of contingent consideration include a significant amount 
of  judgment,  and  any  changes  in  the  underlying 
estimates could have a material impact on the amount 
of  contingent  consideration  expense  recorded  in  any 
given period. 

 
Income Taxes

We  utilize  the  asset  and  liability  method  of 
accounting  for  income  taxes.  Under  this  method, 
deferred tax assets and liabilities are determined based 
on  the  difference  between  the  financial  statement 
carrying amounts and tax basis of assets and liabilities 
using enacted tax rates in effect for years in which the 
temporary differences are expected to reverse. 

On December 22, 2017, the Tax Cuts and Jobs Act 
(Tax Act) was enacted into law. The Tax Act decreased 
the U.S. statutory corporate tax rate for years beginning 
after December 31, 2017, and included other domestic 
and  international  tax  provisions  that  affect  the 
measurement of our deferred tax assets and liabilities. 
As  a  result,  we  revalued  our  deferred  tax  assets  and 
liabilities  as  of  December  31,  2017  and  recorded  a 
deferred  tax  benefit  of  $292.4.  We  recorded  other 
impacts of the Tax Act on a provisional basis in 2017. 
As of December 22, 2018, our accounting for the impact 
of  the  Tax  Act  was  complete.  See  Note  12,  “Income 
Taxes”  to  our  consolidated 
financial  statements 
included elsewhere in this Annual Report on Form 10-K 
for additional information.

If  our  estimate  of  the  tax  effect  of  reversing 
temporary  differences  is  not  reflective  of  actual 
outcomes, is modified to reflect new developments or 
interpretations of the tax law, revised to incorporate new 
accounting principles, or changes in the expected timing 
or manner of the reversal our results of operations could 
be materially impacted. 

We  follow  the  authoritative  guidance  regarding 
accounting  for  uncertainty  in  income  taxes,  which 
prescribes  a  recognition  threshold  and  measurement 
attribute  for  the  financial  statement  recognition  and 
measurement of a tax position taken or expected to be 
taken in a tax return. These unrecognized tax benefits 
relate primarily to issues common among multinational 
corporations  in  our  industry.  We  apply  a  variety  of 
methodologies in making these estimates which include 
studies performed by independent economists, advice 
from industry and subject experts, evaluation of public 
actions taken by the IRS and other taxing authorities, 
as  well  as  our  own  industry  experience.  We  provide 
estimates for unrecognized tax benefits which may be 
subject  to  material  adjustments  until  matters  are 
resolved with taxing authorities or statutes expire. If our 
estimates are not representative of actual outcomes, 
our results of operations could be materially impacted.

We  continue  to  maintain  a  valuation  allowance 
against certain deferred tax assets where realization is 
not certain. We periodically evaluate  the  likelihood of 
the realization of deferred tax assets and reduce the 
carrying  amount  of  these  deferred  tax  assets  by  a 
valuation allowance to the extent we believe a portion 
will  not  be  realized.  We  consider  many  factors  when 
assessing the likelihood of future realization of deferred 

68

tax  assets,  including  our  recent  cumulative  earnings 
experience by taxing jurisdiction, expectations of future 
taxable income, carryforward periods available to us for 
tax reporting purposes, various income tax strategies 
and  other  relevant  factors.  Significant  judgment  is 
required in making this assessment and, to the extent 
future  expectations  change,  we  would  assess  the 
recoverability of our deferred tax assets at that time. If 
we  determine  that  the  deferred  tax  assets  are  not 
realizable 
future  period,  we  would  record 
adjustments to income tax expense in that period, and 
such adjustments may be material.

New Accounting Pronouncements

In February 2016, the FASB issued a new standard 
that  requires  lessees  to  recognize  leases  on-balance 
sheet  and  disclose  key  information  about  leasing 
arrangements. The new standard establishes a right-of-
use (ROU) model that requires a lessee to recognize a 
ROU asset and lease liability on the balance sheet for 
all leases with a term longer than 12 months. Leases 
will  be  classified  as  finance  or  operating,  with 
classification affecting the pattern and classification of 
expense  recognition  in  the  income  statement.  The 
standard  is  effective  on  January  1,  2019,  with  early 
adoption permitted. We adopted the new standard on 
January 1, 2019 and use the effective date as our date 
of initial application. In July 2018, the FASB issued an 
update that provided an additional transition option that 
allows  companies  to  continue  applying  the  guidance 
under the lease standard in effect at that time in the 
comparative  periods  presented  in  the  consolidated 
financial statements. Companies that elect this option 
would  record  a  cumulative-effect  adjustment  to  the 
opening  balance  of  retained  earnings  on  the  date  of 
adoption. We elected this optional transition method. 
We also elected the “package of practical expedients”, 
which  permits  us  not  to  reassess  under  the  new 
standard  our  prior 
lease 
identification,  lease  classification  and  initial  direct 
to  evaluate  other  practical 
costs. We  continue 
expedients available under the standard.

conclusions  about 

We have substantially completed our assessment 
of the standard as well as implementation of our leasing 
software,  including  data  upload  and  test  procedures.  
We continue to finalize our calculations, including our 
discount rate assumptions, related to the new standard. 
We are also continuing to establish new processes and 
internal controls that may be required to comply with the 
new lease accounting and disclosure requirements set 
by  the  new  standard.  We  expect  the  impact  of  the 
standard adoption to decrease our assets, liabilities and 
retained  earnings  within  our  consolidated  balance 
the 
sheet.  These  decreases  will 
derecognition  of  our  existing  assets  and  financing 
obligations related to our build to suit leases offset by 
the recognition of new ROU assets and liabilities as a 
result of the leasing standard.

In  June  2016,  the  FASB  issued  a  new  standard 
intended to improve reporting requirements specific to 
loans, receivables and other financial instruments. The 
new  standard  requires  that  credit  losses  be  reported 
based  on  expected  losses  compared  to  the  current 
incurred  loss  model.  The  new  standard  also  requires 
enhanced  disclosure  of  credit  risk  associated  with 
respective assets. The standard is effective for interim 
and annual periods beginning after December 15, 2019 
with  early  adoption  permitted.  We  are  currently 
assessing the impact of this standard on our financial 
condition and results of operations.

In February 2018, the FASB issued a new standard 
that  would  permit  entities  to  make  a  one  time 
reclassification from accumulated other comprehensive 
income (AOCI) to retained earnings for the stranded tax 
effects resulting from the newly enacted corporate tax 
rates under the Tax Act, that was effective for the year 
ended  December  31,  2017.  The  amount  of  the 
reclassification  is  calculated  on  the  basis  of  the 
difference  between  the  historical  tax  rate  and  newly 
enacted tax rate. The standard is effective for interim 
and annual periods beginning after December 15, 2018 
with  early  adoption  permitted.  We  are  currently 
assessing the impact of this standard on our financial 
condition.

In August 2018, the FASB issued a new standard 
on a customer's accounting for implementation, set-up, 
and other upfront costs incurred in a cloud computing 
arrangement (CCA). Under the new guidance, customers 
will assess if a CCA includes a software license and if 
a CCA does include a software license, implementation 
and set-up costs will be accounted for consistent with 
existing internal-use software implementation guidance. 
Implementation costs associated with a CCA that does 
not  include  a  software  license  would  be  expensed  to 
operating  expenses.  The  standard  also  provides 
classification guidance on these implementation costs 
as  well  as  additional  quantitative  and  qualitative 
disclosures.  The  standard  is  effective  for  public 
business  entities  for  fiscal  years  beginning  after 
December 15, 2019, and interim periods within those 
fiscal  years.  Early  adoption  is  permitted,  including 
adoption in any interim periods. Entities can choose to 
adopt the new guidance prospectively or retrospectively. 
We are currently assessing the impact this standard will 
have on our statement of financial condition and results 
of operations.

Recently Adopted Accounting Pronouncements

In May 2014, the FASB issued a comprehensive 
new  standard  which  amends  revenue  recognition 
principles and provides a single set of criteria for revenue 
recognition  among  all  industries.  The  new  standard 
provides  a  five-step  framework  whereby  revenue  is 
recognized  when  promised  goods  or  services  are 
transferred to a customer at an amount that reflects the 

consideration to which the entity expects to be entitled 
in exchange for those goods or services. We adopted 
the new standard on January 1, 2018.

In January 2017, the FASB issued a new standard 
that clarifies the definition of a business and determines 
when an integrated set of assets and activities is not a 
business. This framework requires that if substantially 
all of the fair value of gross assets acquired or disposed 
of is concentrated in a single asset or group of similar 
identifiable assets, the assets would not represent a 
business. We adopted the new standard on January 1, 
2018  and  applied  the  new  guidance  prospectively  to 
transactions occurring after adoption. We anticipate that 
the  adoption  of  this  new  standard  will  likely  result  in 
more transactions, to the extent that such transactions 
are undertaken by the Company, being accounted for as 
asset acquisitions.

In January 2016, the FASB issued a new standard 
that  changes  accounting  for  equity  investments, 
financial  liabilities  under  the  fair  value  option,  and 
presentation and disclosure requirements for financial 
instruments.  In  addition,  the  FASB  clarified  guidance 
related  to  the  valuation  allowance  assessment  when 
from 
recognizing  deferred 
unrealized losses on available-for-sale debt securities. 
Equity investments with readily determinable fair values 
will be measured at fair value with changes in fair value 
recognized in net income. Companies have the option 
to  either  measure  equity  investments  without  readily 
determinable fair values at fair value, or at cost adjusted 
for changes in observable prices minus impairment. We 
adopted  the  new  standard  on  January  1,  2018,  and 
elected  to  measure  our  existing  equity  investments 
without readily determinable fair values at cost adjusted 
for changes in observable prices minus impairment. In 
connection with the adoption of the new standard, we 
reclassified an immaterial amount of unrealized gains 
on  equity  securities 
from  accumulated  other 
comprehensive  income  to  retained  earnings.  The 
guidance related to equity investments without readily 
determinable  fair  values  was  applied  prospectively  to 
equity  investments  that  existed  as  of  the  date  of 
adoption.  We  will  assess  equity  investments  without 
readily  determinable  fair  values  for  observable  price 
changes and impairment on a quarterly basis. See  Note 
7,  “Other  Investments,”  to  our  consolidated  financial 
statements included elsewhere in this Annual Report on 
Form 10-K for further details.

In March 2017, the FASB issued a new standard 
that improves the presentation of net periodic pension 
cost  and  net  periodic  post  retirement  benefit  cost  by 
requiring the bifurcation of net benefit cost. Under the 
new standard, the service cost component of net benefit 
cost  will  be  presented  with  other  employee  costs  in 
operating  expenses,  while  other  components  will  be 
reported separately in other income and expense. We 
adopted  the  new  standard  on  January  1,  2018.  The 

69

adoption of this standard did not have a material impact 
on our consolidated statements of operations.

In  November  2016,  the  FASB  issued  a  new 
standard  that  clarifies  how  entities  should  present 
restricted cash in the statement of cash flows. Under 
the  new  standard,  changes  in  total  cash,  inclusive  of 
restricted cash, should be reflected in the statement of 
cash  flows.  As  a  result,  transfers  between  cash  and 
restricted  cash  will  no  longer  be  reflected  as  activity 
within the statement of cash flows. We adopted the new 
standard  on  January  1,  2018.  The  adoption  of  this 
standard  did  not  have  a  material  impact  on  our 
consolidated statements of cash flows.

In August 2017, the FASB issued a new standard 
intended to improve and simplify certain aspects of the 

Results of Operations

accounting for hedges. The new standard is intended to 
more closely align hedge accounting with companies’ 
risk management strategies, simplify the application of 
hedge accounting, and increase transparency as to the 
scope and results of hedging programs. It also amends 
the  presentation  and  disclosure  requirements  and 
changes  how  companies  assess  effectiveness.  The 
standard  is  effective  for  interim  and  annual  periods 
beginning after December 15, 2018 with early adoption 
permitted. We early adopted the new standard in the 
second quarter 2018 using the modified retrospective 
method. The adoption of this standard did not have a 
material 
financial 
impact  on  our  consolidated 
statements.

The increase in net product sales for fiscal year 
2018, as compared to fiscal year 2017, was primarily 
due  to  an increase in  unit  volumes  of 20.1%.  This 
increase in unit volumes is primarily due to increased 
global demand for SOLIRIS therapy, including sales to 
patients with gMG, which received regulatory approval 
in  the  second  half  of  2017.  Additional  unit  volume 
increases were due to increased sales of STRENSIQ and 
KANUMA  during  2018  as  a  result  of  our  continuing 
efforts to identify and reach more patients with HPP and 
LAL-D globally.

R&D  expenses  are  comprised  of  costs  paid  for 
clinical  development,  product  development  and 
discovery  research,  as  well  as  costs  associated  with 
certain strategic licensing agreements we have entered 
into with third parties. Clinical development costs are 
comprised of costs to conduct and manage clinical trials 
related  to  eculizumab,  ALXN1210  and  other  product 
candidates.  Product  development  costs  are  those 
incurred in performing duties related to manufacturing

agreements and collaborations and other administrative 
costs incurred during product development. Discovery 
research  costs  are  incurred  in  conducting  laboratory 
studies  and  performing  preclinical  research  for  other 
uses of our products and other product candidates and 
milestone expenses related to our licensing agreements 
and  collaborations  in  the  discovery  stage.  Upfront 
payments include upfront payments related to licenses 
and  collaborations.  Clinical  development  costs  have 
been  accumulated  and  allocated  to  each  of  our 
programs,  while  product  development  and  discovery 
research costs have not been allocated.

Facilities and other R&D expenses consist of costs 
to compensate personnel, to maintain our facilities and 
equipment, and other occupancy costs associated with 
our  research  and  development  efforts.  These  costs 
relate to efforts on our clinical and preclinical products, 
our  product  development  and  our  discovery  research 
efforts. These costs have not been allocated directly to 
each program.

impact of the 2017 restructuring.

During  the  year  ended  December 31,  2017,  we 
incurred  research  and  development  expenses  of 
$878.4, an increase of $121.2, or 16.0%, versus the 
$757.2 incurred during the year ended December 31, 
2016.  The  increase  was  primarily  related  to  the 
following:

•  Increase of $23.0 in direct clinical development 
expenses  related  primarily  to  an  expansion  of 
ALXN 1210 studies.

•  Increase of $36.2 in direct product development 
expenses  related  primarily  to  an  increase  in

to our clinical development programs: 

The  following  graph  summarizes  accumulated 
direct  expenses  related  to  our  clinical  development 
programs from January 1, 2006 to December 31, 2018:

(a)  From  1992  through  2006,  substantially  all  research  and 
development expenses were related to two products, eculizumab and 
pexelizumab. We obtained approval in the U.S. for eculizumab for PNH 
in  2007  and  for  aHUS  in  2010,  and  we  ceased  development  of 
pexelizumab in 2006.

(b) Unallocated costs shared across various development programs.

The  successful  development  of  our  drug 
candidates is uncertain and subject to a number of risks. 
We cannot guarantee that results of clinical trials will 
be favorable or sufficient to support regulatory approvals 
for any of our product development programs. We could 
decide to abandon development or be required to spend 
considerable  resources  not  otherwise  contemplated.

Selling, General and Administrative Expense

Selling General and Administrative Expense (SG&A)
SG&A as a % of net product sales

Our  selling,  general  and  administrative  expense 
includes  commercial  and  administrative  personnel, 
corporate facility and external costs required to support 
the  marketing  and  sales  of  our  commercialized 
products.  These  selling,  general  and  administrative 
costs include: corporate facility operating expenses and 
depreciation; marketing and sales operations in support 
of  our  products;  human  resources;  finance,  legal, 
information 
technology  and  support  personnel 
expenses;  and  other  corporate  costs  such  as 
insurance,  audit,  government 
telecommunications, 
affairs and our global corporate compliance program.

The table below provides information regarding 

selling, general and administrative expense:

•  Increase 

in  external  selling,  general  and 
administrative expenses of $20.2. The increase 
was primarily due to an increase in professional 
services and asset related charges associated 
with 
restructuring 
programs. These increases were partially offset 
by  decreased  distribution  expenses  as 
compared to the same period in 2017.

announced 

previously 

During  the  year  ended  December 31,  2017,  we 
incurred selling, general and administrative expenses 
of $1,094.4, an increase of $141.4, or 14.8%, versus 
year  ended 
the  $953.0 
December 31, 2016. The increase was primarily related 
to the following:

incurred  during 

the 

•  Increase  in  salary,  benefits  and  other  labor 
expenses of $81.5, primarily related to increase 
of commercial activities to support the continued 
global launches of STRENSIQ and KANUMA and 
the launch of SOLIRIS for gMG. Employee related 
costs  associated  with  executive  leadership 
changes  and  incentive  compensation  also 
increased.

•  Increase 

in  external  selling,  general  and 
administrative expenses of $59.9. The increase 
was  primarily  due  to  an  increase  in  charitable 
contributions  and  additional  professional 
services,  offset 
in 
advertising and promotional cost as compared 
to  2016.  The  increase  was  also  due  to  asset 
impairment charges that were recorded in 2017 
related to restructuring activities.

We expect our selling, general and administrative 
expenses to decrease as a percentage of sales in 2019

Acquired In-Process Research and Development

Salary, benefits and other labor expense

External selling, general and administrative
expense

During  the  year  ended  December 31,  2018,  we 
incurred selling, general and administrative expenses 
of $1,111.8, an increase of $17.4, or 1.6%, versus the 
$1,094.4 incurred during the year ended December 31, 
2017.  The  increase  was  primarily  related  to  the 
following:

  For  the  year  ended  December 31,  2018  we 
recorded acquired in-process research and development 
(IPR&D) expense of $1,183.0. The increase in acquired 
IPR&D  for  the  year  ended  December 31,  2018,  as 
compared  to  2017  and  2016,  is  due  to  the  Wilson 
Therapeutics  acquisition  completed  in  the  second 
quarter  of  2018  and  the  Syntimmune  acquisition 

76

completed  in  the  fourth  quarter  of  2018.  The  IPR&D 
assets  associated  with  each  of  these  acquisitions, 
which  were  the  principal  assets  acquired  in  each 
transaction,  had  not  reached  technological  feasibility 
and had no alternative future use as of the acquisition 
date and were therefore expensed in 2018. 

Amortization of Purchased Intangible Assets

milestones.   As  a  result  of  this  agreement  and  the 
probability  of  achieving  the  various  sales  milestones, 
our contingent consideration liability increased by $48.7
in the third quarter 2018.

For the year ended December 31, 2018, changes 
in  the  fair  value  of  contingent  consideration  expense 
primarily reflect the impact of the agreement with Enobia 
to  amend  milestones  and  changes  in  the  expected 
timing of payments of contingent consideration, as well 
as the interest component of contingent consideration 
related to the passage of time.

Restructuring Expenses

Amortization expense associated with purchased 
intangible assets was $320.1, $320.1 and $322.2 for 
the years ended December 31, 2018, 2017 and 2016, 
is  primarily 
respectively.  Amortization  expense 
associated with intangible assets related to STRENSIQ 
and KANUMA. 

Change in Fair Value of Contingent Consideration

For  the  years  ended  December 31,  2018  and 
2017, we recorded $25.5 and $104.6, respectively, in 
restructuring expenses. The charges for the year ended 
2018 were mainly attributable to the relocation of our 
corporate headquarters from New Haven, Connecticut 
to Boston, Massachusetts and other related costs and 
the  charges  for  the  year  ended  2017  were  mainly 
attributable to employee separation costs in connection 
with the 2017 restructuring (as described below).

strategy. 

re-alignment 

In the first quarter of 2017, we initiated a company-
wide  restructuring  designed  to  help  position  the 
Company  for  sustainable,  long-term  growth  that  we 
believe  will  further  allow  us  to  fulfill  our  mission  of 
serving patients and families with rare diseases. The 
initial  restructuring  activities  primarily  focused  on  a 
reduction  of  the  Company's  global  workforce.  In 
September 2017, we committed to an operational plan 
to  re-align  the  global  organization  with  its  refocused 
focused 
The 
corporate 
investments  in  priority  growth  areas  to  maximize 
leadership  in  complement  and  grow  the  rare  disease 
business. The re-alignment also included the relocation 
to  Boston, 
of 
Massachusetts in 2018. Our New Haven, Connecticut 
site  continues  to  support  employees  working  in  the 
research  and  process  development  laboratories,  the 
teams,  nurse  case 
clinical  supply  and  quality 
management  and  a  number  of  important  enterprise 
business services. The 2017 restructuring plan reduced 
the  Company's  global  workforce  by  approximately 
20.0%.  The  restructuring  achieved  cost  savings  by 
the  development  portfolio,  simplifying 
focusing 

the  Company's  headquarters 

For  the  years  ended  December 31,  2018,  2017 
and  2016,  the  change  in  fair  value  of  contingent 
consideration  expense  associated  with  our  prior 
business combinations was $116.5, $41.0 and $35.7, 
respectively. The change in the fair value of contingent 
consideration  will  fluctuate  based  on  the  timing  of 
recognition  of  changes  in  the  probability  of  achieving 
and  the  expected  timing  of  milestone  payments  in 
connection with previous acquisitions.

  In  September  2018,  we  amended  the  terms  of 
certain contingent milestone payments due under our 
prior  merger  agreement  with  Enobia  Pharma  Corp. 
(Enobia),  dated  December  28,  2011. The  agreement 
removed  our  obligations  with  respect  to  a  regulatory 
milestone  and  redistributed  the  contingent  payment 
associated  with  this  milestone  to  various  sales 

77

business  structures  and  processes  across 
the 
Company's  global  operations,  and  closing  of  multiple 
Alexion sites, including ARIMF and certain regional and 
country-based offices.

In the first quarter 2019, we have undertaken 

corporate restructuring activities to re-align our global 
organization with our re-focused strategy, reduce 
costs, and realize operational efficiencies.  We expect 
to incur estimated expenses up to $25.0 associated 
with this recent restructuring by the end of 2019.  For 
additional information on this 2019 corporate 
restructuring activity, see Item 1. “Business - Sales 
and Marketing” elsewhere in this Annual Report on 
Form 10-K.

Impairment of Intangible Assets

As  of  December 31,  2018,  we  reviewed  the 
KANUMA  asset  for  impairment  and  determined  that 
there were no indicators of impairment. We will continue 
to review the related valuation and accounting of this 
asset in future quarters as new information becomes 
available to us. Changes to assumptions used in our 
net  cash  flow  projections  may  result  in  impairment 
charges in subsequent periods. The net book value of 
the KANUMA intangible asset as of December 31, 2018
is $3,252.6.

Other Income and (Expense)

The following table provides information regarding other 
income and expense:

During  the  fourth  quarter  of  2016,  we  reviewed 
SBC-103,  an  early  stage  clinical 
indefinite-lived 
intangible asset related to the Synageva acquisition as 
part of our annual impairment testing. The estimated 
fair  value  that  can  be  obtained  for  this  asset  from  a 
market participant in an arm’s length transaction was 
determined  to  be  $31.0,  which  was  lower  than  the 
carrying amount of the asset. As a result, in the fourth 
quarter 2016, we recognized an impairment charge of 
$85.0  to  write-down  this  asset  to  fair  value.  In  the 
second  quarter  2017,  due  to  clinical  results,  we 
recognized an impairment charge of $31.0 related to 
research  and 
our  SBC-103  acquired 
development asset to write-down the asset to fair value, 
which was determined to be de minimis.

Other Income (expense)

For  the  year  ended  December 31,  2018,  we

Income Taxes 

Tax Expense
Effective Tax Rate

the 

The  income  tax  expense  for  the  years  ended 
December 31, 2018, 2017 and 2016 is attributable to 
the U.S. federal, state and foreign income taxes on our 
profitable  operations.  During 
year  ended 
December 31,  2018,  we  recorded  an  income  tax 
expense of $164.6 and an effective tax rate of 68.0%, 
compared  to  an  income  tax  expense  of  $104.5  and 
$176.8 and an effective tax rate of 19.1% and 30.7% 
for  the  years  ended  December 31,  2017  and  2016, 
respectively. The increase in the effective tax rate during 
2018,  from  19.1%  for  the  year  ended  December 31, 
2017 to 68.0% for the year ended December 31, 2018 
was  primarily  attributable  to  the  acquisitions  of 
Syntimmune  and  Wilson  Therapeutics.  Absent 
successful clinical results and regulatory approval, there 
is no alternative future use for the in-process research 
assets we acquired in these acquisitions. Accordingly, 
the  value  of  the  assets  acquired  of  $1,183.0  were 
expensed  as  acquired 
research  and 
development,  for  which  no  tax  benefit  has  been 
recognized. The Syntimmune and Wilson Therapeutics 
acquisitions resulted in an increase in the effective tax 
rate  of  approximately  102.6%.  This  increase  was 
partially offset by the decrease to the U.S. statutory rate 
and other related adjustments as a result of the Tax Act. 
These  items  resulted  in  a  decrease  of  approximately 
45.7%.

in-process 

In December 2017, the Tax Act was enacted into 
law. The Tax Act decreased the U.S. federal corporate 
tax rate to 21.0%, imposed a minimum tax on foreign 
earnings and incorporated a one-time transition tax on 
previously unremitted foreign earnings. We incorporated 
the impact of the Tax Act in our results of operations or 
calculated provisional amounts for the tax effects of the 
Tax Act that could be reasonably estimated for the year 
ended December 31, 2017. We recorded adjustments 
to  this  provisional  accounting  during  2018,  which 

79

resulted  in  a  decrease  to  tax  expense  of  $56.5.  We 
completed our accounting for the Tax Act in the fourth 
quarter 2018. 

The Tax Act resulted in an increase to tax expense 
for the year ended December 31, 2017 of $45.8. This 
increase included a transition tax expense of $177.9
and  deferred  tax  expense  related  to  the  new  GILTI 
minimum tax of $165.4, partially offset by the $297.5
benefit of re-measuring balance sheet taxes to the new 
21.0% US federal tax rate. The re-measurement benefit 
included  $292.4  related  to  decreases  to  our  net 
deferred tax liability and $5.1 related to decreases to 
income taxes payable. The deferred tax expense related 
to the GILTI minimum tax included incremental deferred 
tax  of  $236.9,  net  of  a  related  $71.5  decrease  for 
uncertain tax positions.

The decrease in the effective tax rate during 2017, 
from 30.7% for the year ended December 31, 2016 to 
19.1%  for  the  year  ended  December 31,  2017  was 
primarily attributable to the net increase to tax expense 
in 2017 of $45.8 attributable to the Tax Act, offset by 
decreases  attributable  to  the  deferred  tax  cost  of 
$119.3 associated with the distribution of earnings from 
our  captive  foreign  partnership  in  2016  and  the 
conclusion of the IRS examination of our 2013 and 2014 
tax years in 2017. The impact of the enactment of the 
Tax Act increased our effective tax rate in 2017 by 8.4%. 
The 2016 distribution of earnings increased our 2016 
effective  tax  rate  by  20.7%.  Conclusion  of  the  IRS 
examination resulted in a decrease to our 2017 effective 
tax  rate  of  approximately  3.6%  for  the  year  ended 
December 31, 2017.

We  continue  to  maintain  a  valuation  allowance 
against  certain  other  deferred  tax  assets  where 
realization is not certain. We periodically evaluate the 
likelihood of realizing deferred tax assets and reduce 
the carrying amount of these deferred tax assets by a 
valuation allowance to the extent we believe a portion 
will not be realized.

operations. We expect to continue to be able to fund 
our  operations, 
interest 
payments  on  our  Amended  and  Restated  Credit 
Agreement  and  contingent  payments 
from  our 
acquisitions  principally  through  our  cash  flows  from 
operations.  We  may,  from  time  to  time,  also  seek 
additional  funding  through  a  combination  of  equity  or 
debt financings or from other sources, if necessary for 
future  acquisitions  or  other  strategic  purposes.  New 
sources  of  financing  through  equity  and/or  debt 
financing(s) may not always be available on acceptable 
terms, or at all, and we may be required to obtain certain 
consents in connection with completing such financings.

Financial Instruments

Until  required  for  use  in  the  business,  we  may 
invest our cash reserves in money market funds, bank 
deposits,  reverse  repurchase  agreements,  and  high-
quality marketable debt securities in accordance with 
our  investment  policy.  The  stated  objectives  of  our 
investment  policy  are  to  preserve  capital,  provide 
liquidity  consistent  with 
flow 
requirements, maintain appropriate diversification and 
generate returns relative to these investment objectives 
and prevailing market conditions.

forecasted  cash 

Financial instruments that potentially expose us to 
concentrations  of  credit  risk  are  cash  equivalents, 
marketable  securities,  accounts  receivable  and  our 
derivative  contracts.  At  December 31,  2018,  three 
customers  accounted  for  48.7%  of  the  accounts 
receivable  balance,  with  these  individual  customers 
accounting  for  14.0%  to  19.1%  of  the  accounts

customers  accounted  for  57.7%  of  the  accounts 
receivable  balance,  with  these  individual  customers 
accounting  for  10.2%  to  18.9%  of  the  accounts 
receivable balance. 

For  the  year  ended  December 31,  2018,  four
customers accounted for 50.3% of our product sales, 
with these individual customers ranging from 10.0% to 
16.4%  of  product  sales.  For 
the  year  ended 
December 31,  2017,  three  customers  accounted  for 
37.0%  of  our  product  sales,  with  these  individual 
customers  ranging  from  10.8%  to  15.0%  of  product 
sales. For the year ended December 31, 2016, three
customers accounted for 36.7% of our product sales, 
with these individual customers ranging from 10.0% to

economies and the associated impacts on the financial 
markets  and  our  business.  Substantially  all  of  our

from  wholesale 
distributors,  public  hospitals  and  other  government 
entities.  We  monitor  the  financial  performance  of  our 
customers  so  that  we  can  appropriately  respond  to 
changes in their credit worthiness. We operate in certain 
jurisdictions  where  weakness  in  economic  conditions 
can result in extended collection periods. We continue 
to monitor these conditions and assess their possible 
impact  on  our  business.  To  date,  we  have  not 
experienced  any  significant  losses  with  respect  to 
collection of our accounts receivable. 

We manage our foreign currency transaction risk 
and interest rate risk within specified guidelines through 
the use of derivatives. All of our derivative instruments 
are utilized for risk management purposes, and we do 
not use derivatives for speculative trading purposes. As 
of  December 31,  2018,  we  had  foreign  exchange 
forward  contracts  with  notional  amounts  totaling 
$2,523.0. These outstanding foreign exchange forward 
contracts had a net fair value liability of $18.9, of which 
$40.8 is included in other current assets and noncurrent 
assets and $21.9 is included in other current liabilities 
and noncurrent liabilities. As of December 31, 2018, we 
had interest rate swap contracts with notional amounts 
totaling $3,881.3. These outstanding interest rate swap 
contracts had a net fair value of $2.0, of which $20.1
is included in other current assets and $18.1 is included 
in other current liabilities and noncurrent liabilities. The 
counterparties  to  these  contracts  are  large  domestic 
and multinational commercial banks, and we believe the 
risk of nonperformance is not material.

At December 31, 2018, our financial assets and 
liabilities were recorded at fair value. We have classified 
our  financial  assets  and  liabilities  as  Level  1,  2  or  3 
within the fair value hierarchy. Level 1 inputs are quoted 
prices  (unadjusted)  in  active  markets  for  identical 
assets or liabilities. Our Level 1 assets consist of mutual

At December 31, 2018, the purchase agreements 
for  our  business  combinations  include  contingent 
payments totaling up to $702.0 that will become payable 
if  and  when  certain  development  and  commercial 
milestones are achieved. Of these milestone amounts, 
$367.0 and $335.0 of the contingent payments relate 
to 
commercial  milestones, 
respectively. We do not expect these amounts to have 
an impact on our liquidity in the near-term, and, during 
the  next  12  months,  we  expect  to  make  milestone 
payments of approximately $100.0 associated with our 
prior  business  combinations.  As  additional  future 
payments become probable, we will evaluate methods 
of  funding  payments,  which  could  be  made  from 
available  cash  and  marketable  securities,  cash

equity  investment.  The  market  value  of  the  equity 
investment  was  $10.3  as  of  the  date  of  acquisition, 
which we recorded in other assets in our consolidated 
balance sheets. Due to the early stage of the assets we 
are  licensing,  we  recorded  expense  for  the  upfront 
license  payment  of  $26.7  during  the  fourth  quarter 
2018. In addition, as of December 31, 2018, we could 
also be required to pay up to approximately $625.0 for 
option  exercise  fees  and  amounts  due  upon  the 
achievement  of  specified  research,  development, 
regulatory  and  commercial  milestones,  as  well  as 
royalties on commercial sales.

In December 2017, we entered into a collaboration 
and license agreement with Halozyme Therapeutics, Inc. 
that  allows  us  to  use  drug-delivery  technology  in  the 
development  of  subcutaneous  formulations  for  our 
portfolio of products for up to four targets. Due to the 
early stage of the assets we are licensing, we recorded 
expense for the upfront payment of $40.0 during the 
fourth quarter 2017. In addition, as of December 31, 
2018, we could be required to pay an additional $160.0
for  each  target  developed,  subject  to  achievement  of 
specified  development,  regulatory  and  sales-based 
milestones, as well as royalties on commercial sales.

In  addition,  we  have  entered  into  other  license 
agreements under which we may be required to pay up 
to  an  additional  $137.2  if  certain  development, 
regulatory and commercial milestones are met.

We do not expect the payments associated with 
milestones under our asset acquisitions and licensing 
agreements to have a significant impact on our liquidity 
in the near-term. During the next 12 months, we may 
make  milestone  payments 
these 
arrangements of approximately $255.0.

Financing Lease Obligations

In  November  2012,  we  entered  into  a  lease 
agreement  for  office  and  laboratory  space  to  be 
constructed in New Haven, Connecticut. The term of the 
lease commenced in 2015 and will expire in 2030, with 
a renewal option of ten years. Although we do not legally 
own the premises, we are deemed to be the owner of 
the  building  due  to  the  substantial  improvements 
directly funded during the construction period based on 
applicable accounting guidance for build-to-suit leases. 
Accordingly,  the  landlord’s  costs  of  constructing  the 
facility during the construction period are required to be 
capitalized,  as  a  non-cash  transaction,  offset  by  a 
corresponding 
in  our 
consolidated  balance  sheet.  Construction  of  the  new 
facility was completed and the building was placed into 
service in the first quarter 2016. Associated with this 
arrangement we recognized interest expense of $13.3, 
$14.2, and $14.0 for the years ended December 31, 
2018,  2017,  and  2016, 
respectively.  As  of 
December 31, 2018 and 2017, our total facility lease

During the third quarter 2015, we entered into an 
agreement with Lonza Group AG and its affiliates (Lonza) 
whereby  Lonza  will  construct  a  new  manufacturing 
facility  dedicated  to  Alexion  at  one  of  its  existing 
facilities.  As  a  result  of  our  contractual  right  to  full 
capacity of the new manufacturing facility, a portion of 
the payments under the agreement are considered to 
be lease payments and a portion as payment for the 
supply of inventory. Although we will not legally own the 
premises,  we  are  deemed  to  be  the  owner  of  the 
manufacturing  facility  during  the  construction  period 
based on applicable accounting guidance  for  build-to-
suit  leases  due  to  our  involvement  during  the 
construction period. Accordingly, the landlord’s costs of 
constructing the facility during the construction period 
are required to be capitalized, as a non-cash transaction, 
offset by a corresponding facility lease obligation in our 
consolidated balance sheet. We expect the completion 
of the facility, including obtaining regulatory approval, to 
be in  2019. As of December 31, 2018 and 2017, we 
recorded a construction-in-process asset of $203.9 and 
$180.6,  respectively,  and  an  offsetting  facility  lease 
obligation  of  $155.1  and  $159.1,  respectively,  within 
other current liabilities and facility lease obligation in 
our consolidated balance sheets.

In  September  2017,  we  entered  into  a  lease

commenced upon the landlord's substantial completion 
of the facility during the second quarter of 2018 and will 
expire on the thirteenth anniversary of commencement, 
with an option to renew for up to an additional 10 years. 
Although we do not legally own the premises, due to our 
involvement  during  the  construction  period,  we  are 
deemed to be the owner of the portion of the building 
that  we  will  lease  based  on  applicable  accounting 
guidance  for  build-to-suit  leases.  Accordingly,  the 
landlord's costs of constructing the facility during the 
construction period are required to be capitalized, as a 
non-cash transaction, offset by a corresponding facility 
lease  obligation  in  our  consolidated  balance  sheet. 
Interest  expense  recognized  during  2018  was  not 
material. As of December 31, 2018 and 2017, our total 
facility 
lease  obligation  was  $83.6  and  $59.6, 
respectively, recorded within facility lease obligation in 
our consolidated balance sheets.

Our facility lease obligations will be derecognized 
in  2019  upon  adoption  of  the  new  lease  accounting 
standard and will be replaced by ROU liabilities going 
forward. See Note 1 Business Overview and Summary 
of  Significant Accounting  Policies  to  our  Consolidated 
Financial Statements included elsewhere in this Annual

Long-term Debt

On June 7, 2018, Alexion entered into an Amended 
and Restated Credit Agreement (the Credit Agreement) 
with Bank of America N.A. as administrative agent. The 
Credit  Agreement  amends  and  restates  our  credit 
agreement dated as of June 22, 2015 (the Prior Credit 
Agreement).  The  Credit  Agreement  provides  for  a 
$2,612.5 term loan facility and a $1,000.0 revolving 
facility.  Borrowings  can  be  used  for  working  capital 
requirements, acquisitions and other general corporate 
purposes.  Beginning with the quarter ending June 30, 
2019, we are required to make amortization payments 
of 5.00% of the aggregate principal amount of the term 
loan  facility  annually,  payable  in  equal  quarterly 
installments. 

As  of  December 31,  2018,  we  had  $2,612.5
outstanding on the term loan and $250.0 of borrowings 
outstanding  under  the  revolving  credit  facility.  The 
$250.0 of proceeds on the revolving credit facility was 
used to refinance amounts outstanding under the Prior 
Credit Agreement. As of December 31, 2018, we had 
open letters of credit of $1.7 that offset our borrowing 
availability on the revolving facility. In January 2019 we 
paid the outstanding revolving credit facility of $250.0
in full.

Manufacturing Obligations

We have supply agreements with Lonza relating to 
the  manufacture  of  SOLIRIS  and  STRENSIQ,  which 
requires payments to Lonza at the inception of contract 
and  upon  the  initiation  and  completion  of  product 
manufactured.  On  an  ongoing  basis,  we  evaluate  our 
plans for future levels of manufacturing by Lonza, which 
depends  upon  our  commercial  requirements  and  the 
progress of our clinical development programs.

We  have  various  agreements  with  Lonza,  with 
total  non-cancellable  commitments  of

through  2029.  Certain

agreements  with  Lonza  without  cause,  we  will  be

under our arrangement. Under an existing arrangement 
with  Lonza,  we  also  pay  Lonza  a  royalty  on  sales  of 
SOLIRIS  that  was  manufactured  at  ARIMF  prior  to  its 
sale and a payment with respect to sales of SOLIRIS 
manufactured at Lonza facilities.

In  addition  to  Lonza,  we  have  non-cancellable 
commitments of approximately $104.1 through 2020 
with other third party manufacturers.

Taxes

We have recorded tax on the undistributed earnings 
of our controlled foreign corporation (CFC) subsidiaries. 
To the extent CFC earnings may not be repatriated to 
the  U.S.  as  a  dividend  distribution  due  to  limitations 
imposed  by  law,  we  have  not  recorded  the  related 
potential  withholding,  foreign  local,  and  U.S.  state 
income taxes.

Common Stock Repurchase Program

In  November  2012,  our  Board  of  Directors 
authorized a share repurchase program. The repurchase 

program does not have an expiration date, and we are 
not obligated to acquire a particular number of shares. 
The  repurchase  program  may  be  discontinued  at  any 
time at the Company’s discretion. In February 2017, our 
Board of Directors increased the amount that we are 
authorized to expend on future repurchases to $1,000
under  the  repurchase  program,  which  superseded  all 
prior  repurchase  programs.  Under  the  program,  we 
repurchased 0.7 and 4.0 shares of our common stock 
at a cost of $85.0 and $463.6 during the years ended 
December 31,  2018  and  2017,  respectively.  As  of 
December 31,  2018,  there  is  a  total  of  $451.5
remaining for repurchases under the program.

During  2018,  we  also  had  lower  cash  outlays 
associated  with  the  purchase  of  property,  plant  and 
equipment of $213.0 as compared to $357.3 in 2017. 
The  significant  spending  on  property,  plant  and 
equipment in 2017 related primarily to the construction 
of our new biologics manufacturing facilities in Ireland. 

Financing Activities

Cash  flows  used  in  financing  activities  in  2018
were  $102.4  compared  to  $596.6  in  2017.  The 
decrease  in  cash  used  for  financing  activities  was 
primarily  due  to  repurchasing  $378.6  less  of  our 
common stock in 2018 than 2017. Additionally, cash 
used for financing activities decreased as a  result of 
reduced net payments on our outstanding credit facility 
of $43.8 in 2018,compared to $175.0 in 2017.

(1) Includes our term loan and the $250.0 revolving credit facility balance. Our revolving credit facility is classified as 
a current liability and has been included in payments to be made within one year. In January 2019, we paid the revolving 
credit facility of $250.0 in full.
(2) Interest on variable rate debt is calculated based on interest rates at December 31, 2018. Interest that is fixed, 
associated to our interest rate swaps, is calculated based on the fixed interest swap rate at December 31, 2018.

(3) Facility lease obligations include the lease agreement signed in November 2012, for office and laboratory space in 
New Haven, Connecticut and the lease agreement signed in September 2017 for office space in Boston, Massachusetts. 
In the fourth quarter of 2018 we amended the New Haven lease agreement significantly reducing our leased square 
footage in the building beginning in 2019 through the expiration of the lease (in connection with this amendment, in 
the fourth quarter of 2018, we made a payment of $53.0 to a third party as in incentive to lease the released square 
footage). Although we do not legally own these premises, we were deemed to be the owner of the buildings during the 
construction period based on applicable accounting guidance for build-to-suit leases due to our involvement during 
the construction period. Accordingly, the landlord’s costs of constructing the facility are required to be capitalized, as 
a non-cash transaction, offset by a corresponding facility lease obligation in our consolidated balance sheet.
(4)  Clinical  and  manufacturing  development  commitments  include  only  non-cancellable  commitments,  including  all 
Lonza agreements, at December 31, 2018. 

The contractual obligations table above does not 
include  contingent  royalties  and  other  contingent 
contractual payments we may owe to third parties in the 
future because such payments are contingent on future 
sales of our products and the existence and scope of 
third party intellectual property rights and other factors 
described  in  Item  1A  “Risk  Factors”  and  Note  11 
“Commitments and Contingencies” to the Consolidated 
Financial Statements included elsewhere in this Annual 
Report on Form 10-K.

The liability for unrecognized tax benefits related 
to various federal, state and foreign income tax matters 
of $92.7 at December 31, 2018 was not included within 
the table above. The timing of the settlement of these 
amounts  was 
at 
December 31,  2018.  We  do  not  expect  payment  of 
amounts related to the unrecognized tax benefits within 
the next twelve months.

are achieved. During the next 12 months, we expect to 
make  milestone  payments  of  approximately  $100.0
associated  with  our  prior  business  combinations. 
Commitments related to asset acquisitions and license 
agreements  include  contingent  payments  that  will 
become  payable  if  and  when  certain  development, 
regulatory  and  commercial  milestones  are  achieved. 
During  the  next  12  months,  we  may  make  milestone 
payments related to our asset acquisitions and license 
agreements of approximately $255.0.

Future obligations related to our defined benefit 
plans are not included within the table above, as the 
timing  and  amounts  of  these  payments  was  not 
reasonably estimable as of December 31, 2018. The 
total unfunded obligation on our defined benefit plans 
as  of  December 31,  2018  was  $17.6.  Our  unfunded 
obligation can be impacted by changes in the laws and 
regulations,  interest  rates,  investment  returns,  and 
other variables.

Credit Facilities

On June 7, 2018, we entered into an Amended and 
Restated Credit Agreement (the Credit Agreement), with 
Bank of America N.A. as administrative agent. The Credit 
Agreement amends and restates our agreement dated 
as of June 22, 2015 (the Prior Agreement). 

The  Credit  Agreement  provides  for  a  $1,000.0 
revolving credit facility and a $2,612.5 term loan facility. 
The revolving credit facility and term loan facility mature 
on June 7, 2023. Beginning with the quarter ending June 
30,  2019,  we  are  required  to  make  amortization 
payments of 5.00% of the aggregate principal amount 
of  the  term  loan  facility  annually,  payable  in  equal 
quarterly installments.

Loans under the Credit Agreement bear interest, 
at our option, at either the base rate or a Eurodollar rate, 
in each case plus an applicable margin. Under the Credit 
Agreement, the applicable margins on base rate loans 
range from 0.25% to 1.00% and the applicable margins 
on Eurodollar loans range from 1.25% to 2.00% in each 
case based on our consolidated net leverage ratio (as 
calculated  in  accordance  with  the  Credit  Agreement). 
Our  obligations  under  the  Credit  Agreement  are 
guaranteed  by  certain  of  our  foreign  and  domestic 
subsidiaries  and  secured  by  liens  on  certain  of  our 
subsidiaries’  equity  interests,  subject  to  certain 
exceptions.  Under the terms of the Credit Agreement, 
we must maintain a ratio of total net debt to EBITDA of 
3.50 to 1.00 (subject to certain limited adjustments) 
and EBITDA to cash interest expense ratio of at least 
3.50 to 1.00, in each case as calculated in accordance 
with the Credit Agreement.

to  certain  increases  following  designated  material 
acquisitions.

Operating Leases

Our operating leases are principally for facilities 
and equipment. We currently lease office space in the 
U.S. and foreign countries to support our operations as 
a global organization.

We believe that our administrative office space is 
adequate to meet our needs for the foreseeable future. 
We  also  believe  that  our  research  and  development 
facilities and our manufacturing facilities, together with 
third party manufacturing facilities, will be adequate for 
our on-going activities. 

In addition to the minimum rental commitments 
on our operating leases we may also be required to pay 
amounts for taxes, insurance, maintenance and other 
operating expenses.

Commercial Commitments

Our commercial commitments consist of research 
and  development, 
license,  operational,  clinical 
development,  and  manufacturing  cost  commitments, 
along  with  anticipated  supporting  arrangements, 
subject to certain limitations and cancellation clauses. 
The  timing  and 
level  of  our  commercial  scale 
manufacturing costs, which may or may not be realized, 
are  contingent  upon  the  progress  of  our  clinical 
development  programs  and  our  commercialization 
plans. Our commercial commitments are represented 
principally  by  our  supply  agreements  with  Lonza 
described above. Our commitments with Lonza do not 
include amounts for estimated consumer price index, or 
CPI, adjustments which we are obligated to pay to Lonza.

As of December 31, 2018, we invested our cash

Changes  in  interest  rates  related  to  the  Credit 
Agreement could have a material effect on our financial 
statements. 

To  achieve  a  desired  mix  of  floating  and  fixed 
interest rates on our term loan, we entered into a number 
of interest rate swap agreements that qualified for and 
are  designated  as  cash 
flow  hedges.  As  of 
December 31,  2018,  we  had  cash  flow  hedges  with 
aggregate  amounts  of  approximately  87.0%  of  our 
current outstanding term loan covering periods over the 
next twelve months. If interest rates were to increase 
or decrease by 1.00%, interest expense, over the next 
year would increase or decrease by $3.0, based on the 
unhedged  portion  of  our  outstanding  term  loan  as  of 
December 31, 2018.

Foreign Exchange Market Risk

Our operations include activities in many countries 
outside the U.S. As a result, our financial results are 
impacted by factors such as changes in foreign currency 

exchange  rates  or  weak  economic  conditions  in  the 
foreign markets where we operate. We have exposure 
to movements in foreign currency exchange rates, the 
most  significant  of  which  are  the  Euro  and  Japanese 
Yen,  against  the  U.S.  dollar. We  are  a  net  receiver  of 
many foreign currencies, and our consolidated financial 
results  benefit  from  a  weaker  U.S.  dollar  and  are 
adversely impacted by a stronger U.S. dollar relative to 
foreign currencies in which we sell our products.  

in 

foreign 

denominated 

Our  monetary  exposures  on  our  balance  sheet 
arise  primarily  from  cash,  accounts  receivable,  and 
currencies. 
payables 
Approximately  49.0%  of  our  net  product  sales  were 
denominated in foreign currencies during 2018, and our 
revenues are also exposed to fluctuations in the foreign 
currency  exchange  rates  over  time. In  certain  foreign 
countries, we may sell in U.S. dollar, but our customers 
may  be  impacted  adversely  by  fluctuations  in  foreign 
currency  exchange  rates  which  may  also  impact  the 
timing and amount of our revenue.

Both  positive  and  negative  impacts  to  our 
international product sales from movements in foreign 
currency exchange rates are only partially mitigated by 
the  natural,  opposite  impact  that  foreign  currency 
exchange  rates  have  on  our  international  operating 
expenses.  Additionally,  we  have  operations  based  in 
Europe and accordingly, our expenses are impacted by 
fluctuations in the value of the Euro against the U.S. 
dollar.

(in  some  currencies), 

We currently have a derivative program in place to 
achieve  the  following:  (1)  limit  the  foreign  currency 
exposure of our monetary assets and liabilities on our 
balance sheet, using contracts with durations up to 6 
months  and  (2)  hedge  a  portion  of  our  forecasted 
product  sales 
including 
intercompany sales, and certain forecasted expenses 
using contracts with durations of up to 60 months. The 
objective of this program is to reduce the volatility of our 
operating 
foreign 
to 
exchange. This  program  utilizes  foreign  exchange 
forward contracts intended to reduce, not eliminate, the 
volatility  of  operating  results  due  to  fluctuations  in 
foreign exchange rates.

fluctuation  of 

results  due 

As  of  December 31,  2018  and  2017,  we  held 
foreign  exchange  forward  contracts  with  notional 
amounts totaling $2,523.0 and $2,708.1, respectively. 
As of December 31, 2018 and 2017, our outstanding 
foreign exchange forward contracts had a net fair value 
of $18.9 and $(47.5), respectively. 

We do not use derivative financial instruments for 
speculative  trading  purposes.  The  counterparties  to 
these  foreign  exchange  forward  contracts  are  large 
domestic  and  multinational  commercial  banks.  We 
believe the risk of counterparty nonperformance is not 
material.

86

Based  on  our  foreign  currency  exchange  rate 
exposures at December 31, 2018, a hypothetical 10% 
adverse fluctuation in exchange rates would decrease 
the fair value of our foreign exchange forward contracts 
that  are  designated  as  cash 
flow  hedges  by 
approximately  $101.5  at  December 31,  2018.  The 
resulting loss on these forward contracts would be offset 
by the gain on the underlying transactions and therefore 
would  have  minimal  impact  on  future  anticipated 
earnings and cash flows. Similarly, adverse fluctuations 
in exchange rates that would decrease the fair value of 
our  foreign  exchange  forward  contracts  that  are  not 
designated as hedge instruments would be offset by a 
positive impact of the underlying monetary assets and 
liabilities.

Credit Risk

As  a  result  of  our  foreign  operations,  we  are 
exposed to changes in the general economic conditions 
in  the  countries  in  which  we  conduct  business.  The 
majority  of  our  receivables  are  due  from  wholesale 
distributors,  public  hospitals  and  other  government 
entities.  We  monitor  the  financial  performance  and 
creditworthiness of our large customers so that we can 
properly assess and respond to changes in their credit 
profile.  We  continue  to  monitor  these  conditions, 
including  the  volatility  associated  with  international 
economies  and  the  relevant  financial  markets,  and 
assess their possible impact on our business. Although 
collection  of  our  accounts  receivables  from  certain 
countries may extend beyond our standard credit terms, 
we do not expect any such delays to have a material 
impact  on  our  financial  condition  or  results  of 
operations.

CONTROLS AND PROCEDURES.

Disclosure Controls and Procedures

We  have  established  disclosure  controls  and 
procedures  to  provide  reasonable  assurance  that 
information is accumulated and communicated to our 
management,  including  our  principal  executive  officer 

87

and  principal  financial  officer,  as  appropriate  to  allow 
timely  decisions  regarding  required  disclosure,  and 
ensure that information required to be disclosed in the 
reports we file or submit under the Securities Exchange 
Act of 1934, as amended (Exchange Act) is recorded, 
processed, summarized and reported, within the time 
periods specified in the SEC’s rules and forms. 

Our  management,  with  the  participation  of  our 
Chief  Executive  Officer  and  Chief  Financial  Officer, 
evaluated the effectiveness of our disclosure controls 
and  procedures,  as  defined  in  Rules  13a-15(e)  and 
15d-15(e) under the Exchange Act, as of December 31, 
2018.  Based  on  this  evaluation,  our  Chief  Executive 
Officer and Chief Financial Officer concluded that as of 
December 31,  2018,  our  disclosure  controls  and 
procedures were effective at the reasonable assurance 
level.

Management’s Report on Internal Control Over Financial 
Reporting

Management  of  the  Company  is  responsible  for 
establishing and maintaining adequate internal control 
over  financial  reporting  as  defined  in  Rules  13a-15(f) 
and  15d-15(f)  under  the  Exchange  Act.  Our  internal 
control over financial reporting is a process designed to 
provide reasonable assurance regarding the reliability 
of  financial  reporting  and  the  preparation  of  financial 
statements  for  external  purposes  in  accordance  with 
generally  accepted  accounting  principles.  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.

Management  conducted  an  evaluation  of  the 
effectiveness  of  our  internal  control  over  financial 
reporting  as  of  December 31,  2018  based  on  the 
framework  in  Internal  Control-Integrated  Framework 
(2013)  issued  by  the  Committee  of  Sponsoring 
Organizations  of  the  Treadway  Commission  (COSO). 
Based on that evaluation, management has concluded 
that  the  Company  maintained  an  effective  internal 
control  over  financial  reporting  as  of  December 31, 
2018.

The  effectiveness  of  our  internal  control  over 
financial reporting as of December 31, 2018 has been 
audited  by  PricewaterhouseCoopers  LLP, 
  an 
independent registered public accounting firm, as stated 
in their report, which is included herein.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control 
over financial reporting that occurred during the quarter 
ended December 31, 2018 that has materially affected, 

 
or is reasonably likely to materially affect, our internal 
control over financial reporting.

Report of Independent Registered Public Accounting Firm 
To the Board of Directors and Stockholders of Alexion Pharmaceuticals, Inc. 

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Alexion Pharmaceuticals, Inc. and its subsidiaries 
(the  “Company”)  as  of  December  31,  2018  and  December  31,  2017  and  the  related  consolidated  statements  of 
operations, comprehensive income, changes in stockholders’ equity and cash flows for each of the three years in the 
period ended December 31, 2018, including the related notes (collectively referred to as the “consolidated financial 
statements”). We also have audited the Company's internal control over financial reporting as of  December 31, 2018, 
based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (COSO). 

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial 
position of the Company as of December 31, 2018 and December 31, 2017 and the results of its operations and its 
cash flows for each of the three years in the period ended December 31, 2018 in conformity with accounting principles 
generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, 
effective internal control over financial reporting as of December 31, 2018, based on criteria established in Internal 
Control - Integrated Framework (2013) issued by the COSO.

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal 
control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, 
included in Management's Report on Internal Control over Financial Reporting under Item 9A. Our responsibility is to 
express  opinions  on  the  Company’s  consolidated  financial  statements  and  on  the  Company's  internal  control  over 
financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting 
Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance 
with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission 
and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and 
perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of 
material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was 
maintained in all material respects.  

Our audits of the consolidated financial statements included performing procedures to assess the risks of material 
misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that 
respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and 
disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used 
and significant estimates made by management, as well as evaluating the overall presentation of the consolidated 
financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal 
control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the 
design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing 
such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable 
basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the 
transactions and dispositions of the assets of the company; (ii) 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 (iii) provide reasonable assurance regarding prevention or timely 

F-2

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.

Business Overview and Summary of Significant Accounting Policies

Business

Alexion Pharmaceuticals, Inc. (Alexion, the Company, we, our or us) is a global biopharmaceutical company focused 
on serving patients and families affected by rare diseases through the innovation, development and commercialization 
of life-changing therapies.

We are the global leader in complement inhibition and have developed and commercialize the only two approved 
complement inhibitors to treat patients with paroxysmal nocturnal hemoglobinuria (PNH), as well as the first and only 
approved  complement  inhibitor  to  treat  atypical  hemolytic  uremic  syndrome  (aHUS)  and  anti-acetylcholine  receptor 
(AchR) antibody-positive generalized myasthenia gravis (gMG).  In addition, Alexion has two highly innovative enzyme 
replacement therapies for patients with life-threatening and ultra-rare metabolic disorders, hypophosphatasia (HPP) and 
lysosomal acid lipase deficiency (LAL-D).

As the leader in complement biology for over 20 years, Alexion focuses its research efforts on novel molecules 
and targets in the complement cascade, and its development efforts on the core therapeutic areas of hematology, 
nephrology, neurology, and metabolic disorders. We were incorporated in 1992 under the laws of the State of Delaware.

Basis of Presentation and Principles of Consolidation

The  accompanying  consolidated  financial  statements  include  the  accounts  of  Alexion  and  its  wholly-owned 
subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. For each of our business 
combinations, all of the assets acquired and liabilities assumed were recorded at their respective fair values as of the 
date of acquisition, and their results of operations are included in the consolidated financial statements from the date 
of acquisition. 

Dividend Policy

We have never paid a cash dividend on shares of our stock. We currently intend to retain our earnings to finance 

future operations and do not anticipate paying any cash dividends on our stock in the foreseeable future.

Critical Accounting Estimates

The preparation of our consolidated financial statements, which have been prepared in accordance with accounting 
principles generally accepted in the U.S., requires us to make estimates, judgments and assumptions that may affect 
the reported amounts of assets, liabilities, revenues, expenses and related disclosure of contingent assets and liabilities 
in our financial statements. We believe the most complex judgments result primarily from the need to make estimates 
about the effects of matters that are inherently uncertain and are significant to our consolidated financial statements. 
We base our estimates on historical experience and on various other assumptions that we believe are reasonable, the 
results of which form the basis for making judgments about the carrying values of assets and liabilities. We evaluate 
our estimates, judgments and assumptions on an ongoing basis. Actual results may differ from these estimates under 
different assumptions or conditions.

The  most  significant  areas  involving  estimates,  judgments  and  assumptions  used  in  the  preparation  of  our 

consolidated financial statements are as follows:

•  Revenue recognition;

•  Contingent liabilities;

• 

Inventories;

•  Share-based compensation;

•  Valuation of goodwill, acquired intangible assets and in-process research and development (IPR&D);

•  Valuation of contingent consideration; and

• 

Income taxes.

(amounts in millions except per share amounts)

Foreign Currency Translation

The financial statements of our subsidiaries with functional currencies other than the U.S. dollar are translated 
into U.S. dollars using period-end exchange rates for assets and liabilities, historical exchange rates for stockholders’ 
equity  and  weighted  average  exchange  rates  for  operating  results.  Translation  gains  and  losses  are  included  in 
accumulated other comprehensive income (loss), net of tax, in stockholders’ equity. Foreign currency transaction gains 
and losses are included in the results of operations in other income and expense.

Cash and Cash Equivalents

Cash and cash equivalents are stated at cost plus accrued interest, which approximates fair value, and include 
short-term highly liquid investments with original maturities of three months or less. As of December 31, 2018 and 2017, 
cash equivalents were comprised of money market funds, reverse repurchase agreements, and other debt securities 
with maturities less than 90 days from the date of purchase.

Fair Value of Financial Instruments

The  carrying  amounts  reflected  in  the  consolidated  balance  sheets  for  cash  and  cash  equivalents,  accounts 
receivable, other assets, accounts payable, accrued expenses and other liabilities approximate fair value due to their 
short-term maturities. Our marketable securities are valued based upon pricing of securities with similar investment 
characteristics and holdings. Our mutual fund investments and equity securities are valued based on quoted market 
prices in active markets with no valuation adjustment.  Investments in equity securities of publicly traded companies 
which are subject to holding period restrictions are carried at fair value using an option pricing valuation model and 
observable market inputs such as the historical volatility of similar companies and risk-free interest rates. Our derivative 
financial instruments are measured at fair value using observable market inputs such as forward rates, interest rates, 
our  own  credit  risk  and  our  counterparties’  credit  risks.  Our  debt  obligations  are  carried  at  historical  cost,  which 
approximates fair value. Our contingent consideration liabilities related to our acquisitions are valued based on various 
estimates, including probability of success, estimated revenues, discount rates and amount of time until the conditions 
of the milestone payments are met.

Marketable Securities

We invest our excess cash balances in marketable securities of highly rated financial institutions and investment-
grade debt instruments. We seek to diversify our investments and limit the amount of investment concentrations for 
individual institutions, maturities and investment types. We classify marketable debt securities as available-for-sale 
and, accordingly, record such securities at fair value. We classify these securities as current assets as these investments 
are intended to be available to the Company for use in funding current operations.

Unrealized  gains  and  losses  on  our  marketable  debt  securities  that  are  deemed  temporary  are  included  in 
accumulated other comprehensive income (loss) as a separate component of stockholders’ equity. If any adjustment 
to fair value reflects a significant decline in the value of the security, we evaluate the extent to which the decline is 
determined to be other-than-temporary and would mark the security to market through a charge to our consolidated 
statement of operations. Credit losses are identified when we do not expect to receive cash flows sufficient to recover 
the amortized cost basis of a security. In the event of a credit loss, only the amount associated with the credit loss is 
recognized  in  operating  results,  with  the  amount  of  loss  relating  to  other  factors  recorded  in  accumulated  other 
comprehensive income (loss).

We sponsor a nonqualified deferred compensation plan which allows certain highly-compensated employees to 
elect  to  defer  income  to  future  periods.  Participants  in  the  plan  earn  a  return  on  their  deferrals  based  on  several 
investments options, which mirror returns on underlying mutual fund investments. We choose to invest in the underlying 
mutual fund investments to offset the liability associated with our nonqualified deferred compensation plan. These 
mutual fund investments are valued at net asset value per share and are carried at fair value with gains and losses 
included  in  investment  income.  The  changes  in  the  underlying  liability  to  the  employee  are  recorded  in  operating 
expenses.

Accounts Receivable

Our standard credit terms vary based on the country of sale and range from 30 to 120 days and all arrangements 
are payable within one year of the transfer of the product. Our consolidated average days’ sales outstanding ranges 
from 60 to 70 days. We evaluate the creditworthiness of customers on a regular basis. The length of time from sale 
to receipt of payment in certain countries exceeds our credit terms. In countries in which collections from customers 
extend  beyond  normal  payment  terms,  we  seek  to  collect  interest. We  record  interest  on  customer  receivables  as 
interest income when collected. Subsequent adjustments for further declines in credit rating are recorded as bad debt 
expense as a component of selling, general and administrative expense. We also use judgments as to our ability to 
collect outstanding receivables and provide allowances for the portion of receivables if and when collection becomes 
doubtful, and we also assess on an ongoing basis whether collectibility is probable at the time of sale. As of December 31, 
2018 and 2017, allowances on receivables were not material.

Concentration of Credit Risk

Financial instruments that potentially expose the Company to concentrations of credit risk are limited to cash 
equivalents, marketable securities, accounts receivable and our foreign exchange derivative contracts. We invest our 
cash reserves in money market funds or high-quality marketable debt securities in accordance with our investment 
policy. The stated objectives of our investment policy is to preserve capital, provide liquidity consistent with forecasted 
cash flow requirements, maintain appropriate diversification and generate returns relative to these investment objectives 
and prevailing market conditions.

At December 31, 2018, three customers accounted for 48.7% of the accounts receivable balance, with these 
individual customers ranging from 14.0% to 19.1% of the accounts receivable balance. At December 31, 2017, four
customers accounted for 57.7% of the accounts receivable balance, with these individual customers ranging from 10.2% 
to 18.9% of the accounts receivable balance. 

For the year ended December 31, 2018, four customers accounted for 50.3% of our product sales, with these 
individual customers ranging from 10.0% to 16.4% of our product sales. For the year ended December 31, 2017, three
customers accounted for 37% of our product sales, with these individual customers ranging from 10.8% to 15.0% of 
our product sales. For the year ended December 31, 2016, three customers accounted for 36.7% of our product sales, 
with these individual customers ranging from 10.0% to 16.0% of our product sales. No other customers accounted for 
more than 10.0% of accounts receivable or net product sales.

We continue to monitor economic conditions, including volatility associated with international economies and the 
associated impacts on the financial markets and our business. Substantially all of our accounts receivable are due 
from wholesale distributors, public hospitals and other government entities. We monitor the financial performance of 
our customers so that we can appropriately respond to changes in their credit worthiness. We can operate in certain 
jurisdictions where weakness in economic conditions can result in extended collection periods. To date, we have not 
experienced any significant losses with respect to collection of our accounts receivable. 

Inventories

Inventories are stated at the lower of cost or net realizable value. Cost is determined in a manner that approximates 

average costs.

The components of inventory are as follows:

Raw materials
Work-in-process
Finished goods

Capitalization of Inventory Costs

We  capitalize  inventory  produced  for  commercial  sale,  which  may  include  costs  incurred  for  certain  products 
awaiting regulatory approval. We capitalize inventory produced in preparation of product launches sufficient to support 
estimated initial market demand. Capitalization of such inventory begins when we have (i) obtained positive results in 
clinical trials that we believe are necessary to support regulatory approval, (ii) concluded that uncertainties regarding 
regulatory approval have been sufficiently reduced, and (iii) determined that the inventory has probable future economic 
benefit. In evaluating whether these conditions have been met, we consider clinical trial results for the underlying product 
candidate, results from meetings with regulatory authorities, and the compilation of the regulatory application. If we 
are aware of any material risks or contingencies outside of the standard regulatory review and approval process, or if 
there are any specific negative issues identified relating to the safety, efficacy, manufacturing, marketing or labeling of 
the product that would have a significant negative impact on its future economic benefits, the related inventory would 
not be capitalized. We had no inventory capitalized for products awaiting regulatory approval as of December 31, 2018
and 2017.

Products that have been approved by the U.S. Food and Drug Administration (FDA) or other regulatory authorities 
are also used in clinical programs to assess the safety and efficacy of the products for usage in diseases that have 
not been approved by the FDA or other regulatory authorities. The form of the products utilized for both commercial and 
clinical programs is identical and, as a result, the inventory has an “alternative future use” as defined in authoritative 
guidance. Raw materials and purchased drug product associated with clinical development programs are included in 
inventory and charged to research and development expense when the product enters the research and development 
process and no longer can be used for commercial purposes and, therefore, does not have an “alternative future use”.

 For products which are under development and have not yet been approved by regulatory authorities, purchased 
drug product is charged to research and development expense upon delivery. Delivery occurs when the inventory passes 
quality  inspection  and  ownership  transfers  to  us.  Nonrefundable  advance  payments  for  research  and  development 
activities, including production of purchased drug product, are deferred and capitalized until the goods are delivered. 
We also recognize expense for raw materials purchased for developmental purposes when the raw materials pass 
quality inspection and we have an obligation to pay for the materials. 

Inventory Write-Offs

We analyze our inventory levels to identify inventory that may expire prior to sale, inventory that has a cost basis 
in  excess  of  its  estimated  realizable  value,  or  inventory  in  excess  of  expected  sales  requirements.  Although  the 
manufacturing of our product is subject to strict quality control, certain batches or units of product may no longer meet 
quality specifications or may expire, which requires adjustments to our inventory values. We also apply judgment related 
to the results of quality tests that we perform throughout the production process, as well as our understanding of 
regulatory guidelines, to determine if it is probable that inventory will be saleable. These quality tests are performed 
throughout the pre-and post-production process, and we continually gather additional information regarding product 
quality for periods after the manufacture date. Our products currently have a maximum estimated life ranging from 36
to 48 months and, based on our sales forecasts, we expect to realize the carrying value of our inventory. In the future, 
reduced demand, quality issues or excess supply beyond those anticipated by management may result in a material 
adjustment to inventory levels, which would be recorded as an increase to cost of sales.

The determination of whether or not inventory costs will be realizable requires estimates by our management. A 
critical input in this determination is future expected inventory requirements based on internal sales forecasts. We then 
compare these requirements to the expiry dates of inventory on hand. For inventories that are capitalized in preparation 
of product launch, we also consider the expected approval date in assessing realizability. To the extent that inventory 
is expected to expire prior to being sold, we will write down the value of inventory.

Derivative Instruments

We record the fair value of derivative instruments as either assets or liabilities on the balance sheet. The accounting 
for gains and losses resulting from changes in fair value is dependent on the use of the derivative and whether it is 
designated and qualifies for hedge accounting.

All qualifying hedging activities are documented at the inception of the hedge and must meet the definition of 
highly effective in offsetting changes to future cash. On a quarterly basis, we perform an assessment to confirm that 
outstanding hedges remain highly effective and continue to qualify for hedge accounting. We record the fair value of 
the qualifying hedges in other current assets, other assets, other current liabilities and other liabilities. All unrealized 

F-13

Alexion Pharmaceuticals, Inc. 

Notes to Consolidated Financial Statements
For the Years ended December 31, 2018, 2017 and 2016
(amounts in millions except per share amounts)

gains and losses on derivatives that are designated and qualify for hedge accounting are reported in other comprehensive 
income (loss) and recognized when the underlying hedged transaction affects earnings. When the forecasted transaction 
occurs, this amount is reclassified into the consolidated statement of operations and presented in the same financial 
statement line item as the hedged item. 

Derivative instruments for which hedge accounting is not applied are recorded at fair value in other current assets 
and other current liabilities. Unrealized gains and losses resulting from changes in the fair value of these derivatives 
are reported in other income and expense.

Property, Plant and Equipment

Property, plant and equipment are stated at cost and are depreciated on a straight-line basis over the estimated 

useful lives of the assets. We estimate economic lives as follows:

•  Building and improvements—fifteen to thirty five years

•  Machinery and laboratory equipment—five to fifteen years 

•  Computer hardware and software—three to seven years

•  Furniture and office equipment— five to ten years

Leasehold improvements and assets under capital lease arrangements are amortized over the lesser of the asset’s 

estimated useful life or the term of the respective lease. Maintenance costs are expensed as incurred.

Construction-in-progress reflects amounts incurred for property, plant, or equipment construction or improvements 

that have not been placed in service.

Assets Held for Sale

We classify assets as held for sale when the following criteria are met: i) management, having the authority to 
approve the action, commits to a plan to sell the asset, ii) the asset is available for immediate sale in its present 
condition subject only to terms that are usual and customary for sales of similar assets, iii) an active program to locate 
a buyer and other actions required to complete the plan to sell the asset have been initiated, iv) the sale of the asset 
is probable, and transfer of the asset is expected to qualify for recognition as a completed sale, within one year, v) the 
asset is being actively marketed for sale at a price that is reasonable in relation to its current fair value, and vi) actions 
required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the 
plan will be withdrawn. Assets that are classified as held for sale are recorded at the lower of their carrying value or 
their fair value less the costs to sell. 

In the third quarter 2017, we announced our intention to close the Alexion Rhode Island Manufacturing Facility 
(ARIMF). In the fourth quarter 2017, we met the criteria for assets held for sale and reclassified the ARIMF assets from 
property, plant and equipment to assets held for sale recorded within prepaid expenses and other current assets. We 
subsequently sold ARIMF during the third quarter of 2018. 

Manufacturing Facilities

We capitalize costs incurred for the construction of facilities which support commercial manufacturing. We also 
capitalize costs related to validation activities which are directly attributable to preparing the facility for its intended 
use, including engineering runs and inventory production necessary to obtain approval of the facility from government 
regulators for the production of a commercially approved drug. When the facility is substantially complete and ready 
for its intended use and regulatory approval for commercial production has been received, we will place the asset in 
service.

The production of inventory for preparing the facility for its intended use requires two types of production: engineering 
runs which are used for testing purposes only and do not result in saleable inventory, and validation runs which are 
used for validating equipment and may result in saleable inventory. The costs associated with inventory produced during 
engineering runs and normal production losses during validation runs are capitalized to fixed assets and depreciated 
over the asset’s useful life. Saleable inventory produced during the validation process is initially treated as a fixed 
asset; however, upon regulatory approval, this inventory is reclassified to inventory and expensed in cost of goods sold 
as product is sold, or in research and development expenses as product is utilized in R&D activities. Abnormal production 
costs incurred during the validation process are expensed as incurred.

(amounts in millions except per share amounts)

Acquisitions

Business  combinations  are  accounted  for  using  the  acquisition  method  of  accounting.  Under  the  acquisition 
method of accounting, the tangible and intangible assets acquired and the liabilities assumed are recorded as of the 
acquisition date at their respective fair values. We evaluate a business as an integrated set of activities and assets 
that is capable of being conducted and managed for the purpose of providing a return in the form of dividends, lower 
costs or other economic benefits and consists of inputs and substantive processes applied to those inputs that have 
the  ability  to  contribute  to  the  creation  of  outputs.  If  substantially  all  of  the  fair  value  of  gross  assets  acquired  is 
concentrated in a single asset or group of similar identifiable assets, the assets do not represent a business. In an 
acquisition of a business, the excess of the fair value of the consideration transferred over the fair value of the net 
assets acquired is recorded as goodwill. 

Acquisitions of assets or group of assets that do not meet the definition of a business are accounted for as asset 
acquisitions using the cost accumulation method, whereby the cost of the acquisition, including  certain transaction 
costs, is allocated to the assets acquired on the basis of relative fair values. No goodwill is recognized in an asset 
acquisition. Intangible assets that are acquired in an asset acquisition for use in research and development activities 
which have an alternative future use are capitalized as in-process research and development (IPR&D).  Acquired IPR&D 
which has no alternative future use is recognized as research and development expense at acquisition.  Contingent 
milestone payments associated with asset acquisitions are recognized when probable and estimable.  These amounts 
are expensed to research and development if there is no alternative future use associated with the asset, or capitalized 
as an intangible asset if alternative future use of the asset exists.

Our consolidated financial statements include the results of operations of an acquired business after the completion 

of the acquisition.

Intangible Assets

Our intangible assets generally consist of licensing rights, patents, purchased technology, acquired IPR&D and 
other intangibles. Intangible assets with definite lives are amortized based on their pattern of economic benefit over 
their estimated useful lives and reviewed periodically for impairment.

Intangible  assets  related  to  IPR&D  projects  are  considered  to  be  indefinite-lived  until  the  completion  or 
abandonment  of  the  associated  research  and  development  efforts.  During  the  period  the  assets  are  considered 
indefinite-lived, they will not be amortized but will be tested for impairment. Impairment testing is performed at least 
annually or when a triggering event occurs that could indicate a potential impairment. If and when development is 
complete, which generally occurs when regulatory approval to market a product is obtained, the associated assets are 
deemed finite-lived and are amortized over a period that best reflects the economic benefits provided by these assets. 

Goodwill

Goodwill represents the excess of purchase price over fair value of net assets acquired in a business combination 
and is not amortized. Goodwill is subject to impairment testing at least annually or when a triggering event occurs that 
could indicate a potential impairment. We are organized and operate as a single reporting unit and therefore the goodwill 
impairment test is performed using our overall market value, as determined by our traded share price, compared to our 
book value of net assets. 

Impairment of Long-Lived Assets

Our long-lived assets are primarily comprised of intangible assets and property, plant and equipment. We evaluate 
our finite-lived intangible assets and property, plant and equipment, for impairment whenever events or changes in 
circumstances indicate the carrying value of an asset or group of assets is not recoverable. If these circumstances 
exist, recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset 
group to future undiscounted net cash flows expected to be generated by the asset group. If such assets are considered 
to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets 
exceeds the fair value of the assets. 

In  addition,  indefinite-lived  intangible  assets,  comprised  of  IPR&D,  are  reviewed  for  impairment  annually  and 
whenever events or changes in circumstances indicate that it is more likely than not that the asset is impaired by 
comparing the fair value to the carrying value of the asset. In the second quarter 2017, we recognized an impairment 
charge of $31.0 related to our SBC-103 acquired in-process research and development asset due to clinical results.

Other Investments

From time to time, we make strategic investments in equity securities of certain biotechnology companies. Our 
strategic investment portfolio may include equity securities in publicly traded companies, as well as investments in 
companies with securities that are not publicly traded and where fair value is not readily available. These investments 
are included in other assets in our consolidated balance sheets. 

We have historically recorded our investments in securities that are not publicly traded at cost, less impairments. 
As of January 1, 2018, we continue to record these investments at cost, less impairments; however, we also adjust 
the investment for any changes resulting from an observable price change in an orderly transaction for identical or 
similar investments of the same issuer. We assess relevant transactions that occur on or before the balance sheet 
date to identify observable price changes, and we regularly monitor these investments to evaluate whether there is an 
indication that the investment is impaired, based on the implied value of recent company financings, public market 
prices of comparable companies, and general market conditions.

Our investments in equity securities in publicly traded companies which are unrestricted are regularly measured 
and carried at fair value and classified as Level 1 equity securities within the fair value hierarchy. Investments in publicly 
traded  companies  which  are  subject  to  holding  period  restrictions  are  carried  at  fair  value  using  an  option  pricing 
valuation  model  and  classified  as  Level  2  equity  securities  within  the  fair  value  hierarchy.  The  most  significant 
assumptions within the option pricing valuation model are the term of the restrictions and the stock price volatility, 
which is based upon the historical volatility of similar companies. We also use a constant maturity risk-free interest 
rate to match the remaining term of the restrictions on such investments.

Contingent Consideration

 We record contingent consideration resulting from a business combination at fair value on the acquisition date. 
On a quarterly basis, we revalue these obligations and record increases or decreases in their fair value as an adjustment 
to operating earnings. Changes to contingent consideration obligations can result from adjustments to discount rates, 
accretion of the liability due to the passage of time, changes in our estimates of the likelihood or timing of achieving 
development or commercial milestones, changes in the probability of certain clinical events or changes in the assumed 
probability associated with regulatory approval.

Contingent Liabilities

We are currently involved in various claims and legal proceedings. On a quarterly basis, we review the status of 
each significant matter and assess its potential financial exposure. If the potential loss from any claim, asserted or 
unasserted, or legal proceeding is considered probable and the amount can be reasonably estimated, we accrue a 
liability for the estimated loss. Because of uncertainties related to claims and litigation, accruals are based on our best 
estimates based on available information. On a periodic basis, as additional information becomes available, or based 
on specific events such as the outcome of litigation or settlement of claims (and our offers of settlement), we may 
reassess the potential liability related to these matters and may revise these estimates (and these revisions may be 
material).

Treasury Stock

Treasury stock is accounted for using the cost method, with the purchase price of the common stock recorded 

separately as a deduction from stockholders’ equity.

Revenue Recognition

In May 2014, the FASB issued a comprehensive new standard which amends revenue recognition principles. We 
adopted the new standard on January 1, 2018 by applying the modified retrospective method to all contracts that were 
not completed as of that date.  Under the new guidance, revenue is recognized when a customer obtains control of 
promised goods or services, in an amount that reflects the consideration expected to be received in exchange for those 
goods or services. Revenue is recognized through a five-step process: (i) identify the contract(s) with a customer; (ii) 
identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction 
price to the performance obligations in the contract; and (v) recognize revenue when (or as) a performance obligation 
is satisfied. The Company only applies the five-step model to contracts when it is probable that the Company will collect 
the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, 
the Company assesses the goods or services promised within each contract, and determines those that are performance

(amounts in millions except per share amounts)

obligations. Revenue is recognized for the applicable performance element when each distinct performance obligation 
is satisfied. 

While results for reporting periods beginning after January 1, 2018 are presented under the new guidance, prior 
period amounts are not adjusted and continue to be reported under the accounting standards in effect for the prior 
period. The adoption of the new standard did not significantly change our accounting policies. 

Nature of Products

Our  principal  source  of  revenue  is  product  sales.  Our  contracts  with  customers  generally  contain  a  single 
performance obligation and we recognize revenue from product sales when we have satisfied our performance 
obligation by transferring control of the product to our customers. Control of the product generally transfers to 
the customer upon delivery. In certain countries, we sell to distributors on a consignment basis and record 
revenue when control of the product transfers to the customer upon sale to the end user.

Our customers are primarily comprised of distributors, pharmacies, hospitals, hospital buying groups, and other 
healthcare providers. In some cases, we may also sell to governments and government agencies. In addition 
to sales in countries where our products are commercially available, we have also recorded revenue on sales 
for patients receiving treatment through named-patient programs. The relevant authorities or institutions in 
those countries have agreed to reimburse for product sold on a named-patient basis where our products have 
not received final approval for commercial sale.

Revenue is recognized at the amount to which we expect to be entitled in exchange for the sale of our products. 
This  amount  includes  both  fixed  and  variable  consideration  and  excludes  amounts  that  are  collected  from 
customers and remitted to governmental authorities, such as value-added taxes in foreign jurisdictions. Shipping 
and handling costs associated with outbound freight after control of a product has transferred to our customers 
are accounted for as a fulfillment cost and are included in operating expenses. The cost for any shipping and 
handling activities (including customs clearance activities) associated with transactions for which revenue has 
been recognized are accrued if not completed before the respective period end. 

The timing between the recognition of revenue for product sales and the receipt of payment is not significant. 
Our  standard  credit  terms,  which  vary  based  on  the  country  of  sale,  range  from  30  to  120  days  and  all 
arrangements are payable within one year of the transfer of the product. We do not assess whether a contract 
has a significant financing component if the expectation at contract inception is such that the period between 
the transfer of the promised good to the customer and receipt of payment will be one year or less.

Variable Consideration

We pay distribution fees to our distributors and offer rebates and/or discounts, or enter into volume-based 
reimbursement arrangements with certain customers. We reduce the transaction price on our sales for these 
amounts. For variable amounts, we estimate the amount of consideration to which we expect to be entitled 
based on all available historic, current and forecast information. We primarily use the expected value method 
to estimate variable payments and, in limited circumstances, will apply the most likely method based on the 
type of variable consideration and what method better predicts the amount of consideration we expect to be 
entitled to. Consideration that is received from a customer that we expect will need to be refunded in the future 
is recorded as a refund liability to the customer within accrued expenses. Actual amounts of consideration 
ultimately  received  or  refunded  may  differ  from  our  estimates.  If  actual  results  in  the  future  vary  from  our 
estimates, we adjust these estimates, which would affect net product sales and earnings in the period such 
variances become known.

Variability in the transaction price for our products pursuant to our contracts with customers primarily arises 
from the following:

Discounts  and  Rebates:  We  offer  discounts  and  rebates  to  certain  distributors  and  customers  under  our 
arrangements. In many cases, these amounts are fixed at the time of sale and the transaction price is reduced 
accordingly. We also provide for rebates under certain governmental programs, including Medicaid in the U.S. 
and other programs outside the U.S., which are payable based on actual claim data. We estimate these rebates 
based on an analysis of historical claim patterns and estimates of customer mix to determine which sales will 
be subject to rebates and the amount of such rebates. We update our estimates and assumptions each period 
and  record  any  necessary  adjustments,  which  may  have  an  impact  on  revenue  in  the  period  in  which  the 

F-17

Alexion Pharmaceuticals, Inc. 

Notes to Consolidated Financial Statements
For the Years ended December 31, 2018, 2017 and 2016
(amounts in millions except per share amounts)

adjustment is made. Generally, the length of time between product sale and the processing and reporting of 
the rebates is three to six months.

Volume-Based Arrangements: We have entered into volume-based arrangements with governments in certain 
countries and other customers in which reimbursement is limited to a contractual amount. Under this type of 
arrangement, amounts billed in excess of the contractual limitation are repaid to the customer as a rebate. 
We estimate incremental discounts resulting from these contractual limitations, based on forecasted sales 
during the limitation period, and we apply the discount percentage to product shipments as a reduction of 
revenue. Our calculations related to these arrangements require estimation of sales during the limitation period, 
and adjustments in these estimates may have a material impact in the period in which these estimates change.

Distribution & Other Fees: We pay distribution and other fees to certain customers in connection with the sales 
of our products. We record distribution and other fees paid to our customers as a reduction of revenue, unless 
the payment is for a distinct good or service from the customer and we can reasonably estimate the fair value 
of the goods or services received. If both conditions are met, we record the consideration paid to the customer 
as an operating expense. These costs are typically known at the time of sale, resulting in minimal adjustments 
subsequent to the period of sale. 

Product Returns: Our contracts with customers generally provide for returns only if the product is damaged or 
defective  upon  delivery.  We  assess  our  sales  transactions  and  arrangements  with  customers  and  monitor 
inventory within our sales channels to determine whether a provision for returns is warranted and a resulting 
adjustment  to  the  transaction  price  is  necessary.  This  assessment  is  based  on  historical  experience  and 
assumptions as of the date of sale and changes in these estimates could have an impact in the period in which 
the change occurs. Because of factors such as the price of our products, the limited number of patients, the 
short period from product sale to patient infusion and limited contractual return rights, our customers often 
carry limited inventory.

The amount of variable consideration included in the transaction price is constrained by the amount that is 
probable will not result in a significant reversal of revenue. We consider our experience with similar transactions 
and expectations regarding the contract in estimating the amount of variable consideration to which we expect 
to be entitled, and determining whether the estimated variable consideration should be constrained. We do 
not have any material constraints on the variable consideration included within the transaction price of our 
current revenue arrangements.

See Note 19 “Segment Information” for a summary of revenue from contracts with customers by product and 

geographical region.

Contract Balances and Receivables

Contract liabilities relate to consideration received and/or billed for goods that have not been delivered to the 
customer and for which the performance obligation has not yet been completed. These amounts are included within 
other current liabilities in the consolidated statements of operations.

Research and Development Expenses

Research and development expenses are comprised of costs incurred in performing research and development 
activities including payroll and benefits, preclinical, clinical trial and related clinical manufacturing costs, manufacturing 
development  and  scale-up  costs,  product  development  and  regulatory  costs,  contract  services  and  other  outside 
contractor costs, research license fees, depreciation and amortization of lab facilities, and lab supplies. These costs 
are expensed as incurred. We accrue costs for clinical trial activities based upon estimates of the services received 
and related expenses incurred that have yet to be invoiced by the contract research organizations, clinical study sites, 
laboratories, consultants, or other clinical trial vendors that perform the activities.

Share-Based Compensation

We have two share-based compensation plans pursuant to which awards are currently being made: (i) the 2017 
Incentive Plan (2017 Plan) and (ii) the 2015 Employee Stock Purchase Plan (ESPP). The 2017 Plan replaced the Amended 
& Restated 2004 Incentive Plan (2004 Plan), effective May 10, 2017. Under the 2017 Plan, restricted stock, restricted 
stock units, stock options and other stock-related awards may be granted to our directors, officers, employees and 
consultants or advisors of the Company or any subsidiary. Under the ESPP, eligible employees can purchase shares of 
common stock at a discount semi-annually through payroll deductions. To date, share-based compensation issued under 
the plans consists of incentive and non-qualified stock options, restricted stock and restricted stock units, including 
restricted stock units with market and non-market performance conditions, and shares issued under our ESPP. 

Compensation expense for our share-based awards is recognized based on the estimated fair value of the awards 
on the grant date. Compensation expense reflects an estimate of the number of awards expected to vest and is primarily 
recognized on a straight-line basis over the requisite service period of the individual grants, which typically equals the 
vesting period. Compensation expense for awards with performance conditions is recognized using the graded-vesting 
method. 

Our estimates of employee stock option values rely on estimates of factors we input into the Black-Scholes model. 
The key factors involve an estimate of future uncertain events. Significant assumptions include the use of historical 
volatility to determine the expected stock price volatility. We also estimate expected term until exercise and the reduction 
in the expense from expected forfeitures. We currently use historical exercise and cancellation patterns as our best 
estimate of future estimated life. 

For  our  non-market  performance-based  awards,  we  estimate  the  anticipated  achievement  of  the  performance 
targets, including forecasting the achievement of future financial targets. These estimates are revised periodically based 
on the probability of achieving the performance targets and adjustments are made throughout the performance period 
as necessary. We use payout simulation models to estimate the grant date fair value of awards with market-based 
performance conditions. The payout simulation models assume volatility of our common stock and the common stock 
of a comparator group of companies, as well as correlations of returns of the price of our common stock and the 
common stock prices of the comparator group.

The purchase price of common stock under our ESPP is equal to 85.0% of the lower of (i) the market value per 
share of the common stock on the first business day of an offering period or (ii) the market value per share of the 
common stock on the purchase date. The fair value of the discounted purchases made under our ESPP is calculated 
using the Black-Scholes model. The fair value of the look-back provision plus the 15.0% discount is recognized as 
compensation expense over the 6 month purchase period.

Restructuring and restructuring related expenses

We record liabilities associated with one-time employee termination benefits and exit or disposal activities in the 
period in which the liability is incurred. One-time employee benefits are incurred when communicated to employees and 
where detailed action plans have been approved.  Costs for one-time termination benefits in which the employee is 
required to render service until termination in order to receive benefits are recognized ratably over the service period. 
For existing benefit arrangements, employee termination costs are accrued when the exit or disposal cost are probable 
and estimable.  

Restructuring related expenses include accelerated depreciation costs and impairment charges associated with 
assets impacted by a restructuring exit activity. Accelerated depreciation costs represent the difference between the 
depreciation expense recognized over the revised useful life of the asset, based upon the anticipated date an impacted 
site closure and the depreciation expense as determined using the useful life prior to the restructuring activities. 

Earnings Per Common Share

Basic earnings per common share (EPS) is computed by dividing net income by the weighted-average number of 
shares of common stock outstanding. For purposes of calculating diluted EPS, the denominator reflects the potential 
dilution that could occur if stock options, unvested restricted stock units or other contracts to issue common stock 
were exercised or converted into common stock, using the treasury stock method.

The following table summarizes the calculation of basic and diluted EPS for years ended December 31, 2018, 

2017 and 2016:

We exclude from EPS the weighted-average number of securities whose effect is anti-dilutive. Excluded from the 
calculation of EPS for the years ended December 31, 2018, 2017 and 2016 were 2.8, 4.0, and 4.2 shares of common 
stock, respectively, because their effect is anti-dilutive. 

Income Taxes

We utilize the asset and liability method of accounting for income taxes. Under this method, deferred tax assets 
and liabilities are determined based on the difference between the financial statement carrying amounts and tax basis 
of assets and liabilities using enacted tax rates in effect for years in which the temporary differences are expected to 
reverse. We periodically evaluate the likelihood of the realization of deferred tax assets and reduce the carrying amount 
of these deferred tax assets by a valuation allowance when it is more likely than not that deferred tax assets will not 
be realized.

We recognize the benefit of an uncertain tax position that has been taken or we expect to take on income tax 
returns if such tax position is more likely than not to be sustained. The tax benefit recognized in the financial statements 
for a particular tax position is based on the largest benefit that is more likely than not to be realized. The amount of 
unrecognized tax benefits is adjusted,  as appropriate,  for  changes in facts and circumstances, such as significant 
amendments to existing tax law, new regulations or interpretations by the taxing authorities, or new information obtained 
during a tax examination or resolution of an examination. We also accrued for potential interest and penalties related 
to unrecognized tax benefits as a component of tax expense.

In December 2017, the Tax Cuts and Jobs Act (Tax Act) was enacted into law. The Tax Act decreased the U.S. 
federal corporate tax rate to 21.0%, imposed a minimum tax on foreign earnings related to intangible assets (GILTI), a

(amounts in millions except per share amounts)

one-time transition tax on previously unremitted foreign earnings, and modified the taxation of other income and expense 
items. With regard to the GILTI minimum tax, foreign earnings are reduced by the profit attributable to tangible assets 
and a deductible allowance of up to 50.0%, subject to annual limitations. We have elected to account for the impact 
of the minimum tax in deferred taxes.

Comprehensive Income

Comprehensive income is comprised of net income and other comprehensive income (loss). Other comprehensive 
income (loss) includes changes in equity that are excluded from net income, such as changes in pension liabilities, 
unrealized gains and losses on marketable debt securities, unrealized gains and losses on hedge contracts and foreign 
currency translation adjustments. Certain of these changes in equity are reflected net of tax.

Reclassifications

Certain items in the prior year’s consolidated financial statements have been reclassified to conform to the current 

presentation.

New Accounting Pronouncements

In February 2016, the FASB issued a new standard that requires lessees to recognize leases on-balance sheet 
and disclose key information about leasing arrangements. The new standard establishes a right-of-use (ROU) model 
that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer 
than  12  months.  Leases  will  be  classified  as  finance  or  operating,  with  classification  affecting  the  pattern  and 
classification of expense recognition in the income statement. The standard is effective on January 1, 2019, with early 
adoption permitted. We adopted the new standard on January 1, 2019 and use the effective date as our date of initial 
application. In July 2018, the FASB issued an update that provided an additional transition option that allows companies 
to continue applying the guidance under the lease standard in effect at that time in the comparative periods presented 
in the consolidated financial statements. Companies that elect this option would record a cumulative-effect adjustment 
to the opening balance of retained earnings on the date of adoption. We elected this optional transition method. We 
also elected the “package of practical expedients”, which permits us not to reassess under the new standard our prior 
conclusions about lease identification, lease classification and initial direct costs. We continue to evaluate other practical 
expedients available under the standard.

We have substantially completed our assessment of the standard as well as implementation of our leasing software, 
including  data  upload  and  test  procedures.    We  continue  to  finalize  our  calculations,  including  our  discount  rate 
assumptions, related to the new standard. We are also continuing to establish new processes and internal controls 
that may be required to comply with the new lease accounting and disclosure requirements set by the new standard. 
We expect the impact of the standard adoption to decrease our assets, liabilities and retained earnings within our 
consolidated balance sheet. These decreases will result from the derecognition of our existing assets and financing 
obligations related to our build to suit leases offset by the recognition of new ROU assets and liabilities as a result of 
the leasing standard. 

In June 2016, the FASB issued a new standard intended to improve reporting requirements specific to loans, 
receivables and other financial instruments. The new standard requires that credit losses be reported based on expected 
losses compared to the current incurred loss model. The new standard also requires enhanced disclosure of credit risk 
associated with respective assets. The standard is effective for interim and annual periods beginning after December 
15, 2019 with early adoption permitted. We are currently assessing the impact of this standard on our financial condition 
and results of operations.

In February 2018, the FASB issued a new standard that would permit entities to make a one time reclassification 
from accumulated other comprehensive income (AOCI) to retained earnings for the stranded tax effects resulting from 
the newly enacted corporate tax rates under the Tax Cuts and Jobs Act (the Tax Act), that was effective for the year 
ended December 31, 2017. The amount of the reclassification is calculated on the basis of the difference between 
the historical tax rate and newly enacted tax rate. The standard is effective for interim and annual periods beginning 
after December 15, 2018 with early adoption permitted. We are currently assessing the impact of this standard on our 
financial condition.

In August 2018, the FASB issued a new standard on a customer's accounting for implementation, set-up, and 
other upfront costs incurred in a cloud computing arrangement (CCA). Under the new guidance, customers will assess 
if a CCA includes a software license and if a CCA does include a software license, implementation and set-up costs 
will be accounted for consistent with existing internal-use software implementation guidance. Implementation costs

(amounts in millions except per share amounts)

associated with a CCA that does not include a software license would be expensed to operating expenses. The standard 
also provides classification guidance on these implementation costs as well as additional quantitative and qualitative 
disclosures. The standard is effective for public business entities for fiscal years beginning after December 15, 2019, 
and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim periods. 
Entities can choose to adopt the new guidance prospectively or retrospectively. We are currently assessing the impact 
this standard will have on our statement of financial condition and results of operations.

Recently Adopted Accounting Pronouncements

In May 2014, the FASB issued a comprehensive new standard which amends revenue recognition principles and 
provides a single set of criteria for revenue recognition among all industries. The new standard provides a five-step 
framework whereby revenue is recognized when promised goods or services are transferred to a customer at an amount 
that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We 
adopted the new standard on January 1, 2018.

In January 2017, the FASB issued a new standard that clarifies the definition of a business and determines when 
an integrated set of assets and activities is not a business. This framework requires that if substantially all of the fair 
value of gross assets acquired or disposed of is concentrated in a single asset or group of similar identifiable assets, 
the assets would not represent a business. We adopted the new standard on January 1, 2018 and applied the new 
guidance prospectively to transactions occurring after adoption. We anticipate that the adoption of this new standard 
will  likely  result  in  more  transactions,  to  the  extent  that  such  transactions  are  undertaken  by  the  Company,  being 
accounted for as asset acquisitions.

In  January  2016,  the  FASB  issued  a  new  standard  that  changes  accounting  for  equity  investments,  financial 
liabilities under the fair value option, and presentation and disclosure requirements for financial instruments. In addition, 
the FASB clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting 
from unrealized losses on available-for-sale debt securities. Equity investments with readily determinable fair values 
will be measured at fair value with changes in fair value recognized in net income. Companies have the option to either 
measure equity investments without readily determinable fair values at fair value, or at cost adjusted for changes in 
observable prices minus impairment. We adopted the new standard on January 1, 2018, and elected to measure our 
existing equity investments without readily determinable fair values at cost adjusted for changes in observable prices 
minus  impairment.  In  connection  with  the  adoption  of  the  new  standard,  we  reclassified  an  immaterial  amount  of 
unrealized gains on equity securities from accumulated other comprehensive income to retained earnings. The guidance 
related to equity investments without readily determinable fair values was applied prospectively to equity investments 
that existed as of the date of adoption. We will assess equity investments without readily determinable fair values for 
observable price changes and impairment on a quarterly basis. Refer to Note 7, Other Investments, for further details.

In March 2017, the FASB issued a new standard that improves the presentation of net periodic pension cost and 
net periodic post retirement benefit cost by requiring the bifurcation of net benefit cost. Under the new standard, the 
service cost component of net benefit cost will be presented with other employee costs in operating expenses, while 
other components will be reported separately in other income and expense. We adopted the new standard on January 
1, 2018. The adoption of this standard did not have a material impact on our consolidated statements of operations.

In November 2016, the FASB issued a new standard that clarifies how entities should present restricted cash in 
the statement of cash flows. Under the new standard, changes in total cash, inclusive of restricted cash, should be 
reflected in the statement of cash flows. As a result, transfers between cash and restricted cash will no longer be 
reflected as activity within the statement of cash flows. We adopted the new standard on January 1, 2018. The adoption 
of this standard did not have a material impact on our consolidated statements of cash flows.

In August 2017, the FASB issued a new standard intended to improve and simplify certain aspects of the accounting 
for hedges. The new standard is intended to more closely align hedge accounting with companies’ risk management 
strategies, simplify the application of hedge accounting, and increase transparency as to the scope and results of 
hedging programs. It also amends the presentation and disclosure requirements and changes how companies assess 
effectiveness. The standard is effective for interim and annual periods beginning after December 15, 2018 with early 
adoption permitted. We early adopted the new standard in the second quarter 2018 using the modified retrospective 
method. The adoption of this standard did not have a material impact on our consolidated financial statements.

Impacts of the New Revenue Standard

We adopted the new revenue standard by applying the modified retrospective method to all contracts that were 
not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented 
under the new standard, while prior period amounts are not adjusted and continue to be reported under the accounting 
standards in effect for the prior period. Upon adoption of the new revenue recognition standard, on January 1, 2018, 
we reduced our deferred revenue balance by $10.4, with an offsetting increase of $6.0 in retained earnings due to the 
cumulative impact of adopting this new standard. 

The impact to net product sales and net income for the year ended December 31, 2018 was an increase of $5.3
and $4.8, respectively, as a result of adopting the new standard. The new standard also resulted in a decrease of $17.9 
in deferred revenue and an increase of $10.8 in retained earnings as of December 31, 2018. The adoption of the new 
revenue standard did not have a material impact on any other balances within the consolidated financial statements 
as of and for the year ended December 31, 2018.

Acquisitions

Wilson Therapeutics AB 

On May 25, 2018, we completed the acquisition of Wilson Therapeutics AB (publ), a biopharmaceutical company 
based in Stockholm, Sweden (Wilson Therapeutics) that develops a novel therapy for patients with rare copper-mediated 
disorders, pursuant to a recommended public cash offer of SEK 232 for each share of stock of Wilson Therapeutics. 
As a result of the acquisition, we added WTX101 (ALXN1840), a highly innovative drug candidate that is currently in the 
early stages of Phase III clinical trials for the treatment of patients with Wilson disease, to our clinical pipeline.

The acquisition of Wilson Therapeutics is accounted for as an asset acquisition, as substantially all of the fair 

value of the gross assets acquired is concentrated in a single asset, WTX101. 

The following table summarizes the total consideration for the acquisition and the value of assets acquired and 

liabilities assumed:

The acquired in-process research and development asset relates to WTX101. Due to the stage of development of 
this asset, significant risk remains and it is not yet probable that there is future economic benefit from this asset. 
Absent successful clinical results and regulatory approval for the asset, there is no alternative future use associated 
with WTX101. Accordingly, the value of this asset of $803.7 was expensed during the year ended December 31, 2018.

Employee related liabilities include the value of outstanding employee equity incentive awards that were accelerated 
in connection with the Wilson Therapeutics acquisition that have been settled in cash. Also included in this amount are 
employer tax obligations associated with the employee equity incentive awards.

In connection with rights to WTX101 that were previously acquired by Wilson Therapeutics from third parties, we 
could be required to pay up to approximately $19.0 if certain development, regulatory and commercial milestones are 
met over time, as well as royalties on commercial sales.

Syntimmune, Inc.

In September 2018, we entered into a definitive agreement to acquire Syntimmune, Inc. (Syntimmune), a clinical-
stage biotechnology company developing an antibody therapy targeting the neonatal Fc receptor (FcRn). Syntimmune’s 
lead candidate, SYNT001 (ALXN1830), is a monoclonal antibody that is designed to inhibit the interaction of FcRn with 
Immunoglobulin G (IgG) and IgG immune complexes, and is being studied in Phase 1b/2a trials for the treatment of 
IgG-mediated autoimmune diseases. The acquisition of Syntimmune closed in November 2018. Under the terms of the 
agreement,  Alexion  acquired  Syntimmune  for  an  upfront  cash  payment  of  $400.0,  with  the  potential  for  additional 
milestone-dependent payments of up to $800.0, for a total value of up to $1,200.0. 

The acquisition of Syntimmune is accounted for as an asset acquisition, as substantially all of the fair value of 

the gross assets acquired is concentrated in a single in-process research and development asset, SYNT001.

The following table summarizes the total consideration for the acquisition and the value of the assets acquired 

and liabilities assumed:

We sponsor a nonqualified deferred compensation plan which allows certain highly-compensated employees to 
elect  to  defer  income  to  future  periods.  Participants  in  the  plan  earn  a  return  on  their  deferrals  based  on  several 
investment options, which mirror returns on underlying mutual fund investments. We choose to invest in the underlying 
mutual fund investments to offset the liability associated with our nonqualified deferred compensation plan. These 
mutual fund investments are valued at net asset value per share and are carried at fair value with gains and losses 
included in investment income. The changes in the underlying liability to the employee are recorded in operating expenses. 
As  of  December 31,  2018  and  December 31,  2017,  the  fair  value  of  these  investments  was  $16.5  and  $18.5, 
respectively.

We utilize the specific identification method in computing realized gains and losses. Realized gains and losses on 

our marketable securities were not material for the years ended December 31, 2018, 2017 and 2016.

Derivative Instruments and Hedging Activities

We operate internationally and, in the normal course of business, are exposed to fluctuations in foreign currency 
exchange rates. The exposures result from portions of our revenues, as well as the related receivables, and expenses 
that are denominated in currencies other than the U.S. dollar, primarily the Euro and Japanese Yen. We are also exposed 
to fluctuations in interest rates on outstanding borrowings under our revolving credit facility and term loan facility. We 
manage these exposures within specified guidelines through the use of derivatives. All of our derivative instruments 
are utilized for risk management purposes, and we do not use derivatives for speculative trading purposes.

We enter into foreign exchange forward contracts, with durations of up to 60 months, to hedge exposures resulting 
from portions of our forecasted revenues, including intercompany revenues, and certain forecasted expenses that are 
denominated in currencies other than the U.S. dollar. The purpose of these hedges is to reduce the volatility of exchange 
rate fluctuations on our operating results. These hedges are designated as cash flow hedges upon contract inception. 
As of December 31, 2018, we had open revenue related foreign exchange forward contracts with notional amounts 
totaling $991.1 that qualified for hedge accounting with current contract maturities through December 2020. As of 
December 31, 2018, we had open expense related foreign exchange forward contracts with notional amounts totaling 
$20.3 that qualified for hedge accounting with contract maturities through September 2022. 

To achieve a desired mix of floating and fixed interest rates on our term loan, we enter into interest rate swap 
agreements that qualify for and are designated as cash flow hedges. These contracts convert the floating interest rate 
on a portion of our debt to a fixed rate, plus a borrowing spread. 

The following tables summarize the total interest rate swap contracts executed as of December 31, 2018:

In January 2019, we entered into an additional interest rate swap agreement with a notional amount of $200.0
that is effective from December 31, 2019 through December 31, 2022 and converts the floating rate on a portion of 
our term loan to a fixed rate of 2.37%, plus a borrowing spread. 

During the second quarter 2018, we adopted the new standard for accounting for hedges that is designed to 
simplify the application of hedge accounting and increase transparency as to the scope and results of hedging programs. 
The updated guidance no longer requires the separate measurement and reporting of hedge ineffectiveness. Following 
adoption, all unrealized gains and losses on derivatives that are designated and qualify for hedge accounting are reported 
in other comprehensive income (loss) and recognized in our consolidated statements of operations when the underlying 
hedged transaction affects earnings. 

The amount of gains and losses recognized in the consolidated statements of operations for the years ended 
December 31, 2018, 2017, and 2016 from foreign exchange and interest rate swap contracts that qualified as cash 
flow hedges were as follows:

Assuming no change in foreign exchange rates from market rates at December 31, 2018, $9.8 of gains recognized 
in AOCI will be reclassified to revenue over the next 12 months. Assuming no change in LIBOR-based interest rates 
from market rates at December 31, 2018, $19.3 of gains recognized in AOCI will be reclassified to interest expense 
over the next 12 months. Amounts recognized in AOCI for expense related foreign exchange forward contracts was 
immaterial as of December 31, 2018.

We enter into foreign exchange forward contracts, with durations up to 6 months, designed to limit the balance 
sheet exposure of monetary assets and liabilities. We enter into these hedges to reduce the impact of fluctuating 
exchange rates on our operating results. Hedge accounting is not applied to these derivative instruments as gains and 
losses on these hedge transactions are designed to offset gains and losses on underlying balance sheet exposures. As 
of December 31, 2018, the notional amount of foreign exchange contracts where hedge accounting is not applied was 
$1,511.6.

We  recognized  a  gain  (loss)  of  $23.0,  $(14.7)  and  $(5.2),  in  other  income  and  expense  for  the  years  ended 
December 31, 2018, 2017 and 2016, respectively, associated with the foreign exchange contracts not designated as

Other Investments

Other  investments  include  strategic  equity  investments  in  Moderna  Therapeutics,  Inc.  (Moderna)  and  Dicerna 

Pharmaceuticals, Inc. (Dicerna).

Moderna

During 2014, we purchased $37.5 of preferred equity of Moderna, a nonpublic biotechnology company, which was 
recorded at cost. During the first quarter of 2018, Moderna announced the completion of a new round of financing. We 
considered this transaction and the rights of the new shares issued in the new round, compared to the rights of the 
preferred equity that we hold, and concluded that Moderna’s new round of financing represented an observable price 
change in an orderly transaction for a similar investment. We further concluded, based on the respective rights of the 
stock and consideration of potential liquidity events, that the value of our preferred stock was equivalent to the value 
of the newly issued preferred stock. As a result, we recognized an unrealized gain of $100.8 in investment income 
during the first quarter 2018 to adjust our equity investment in Moderna to fair value as of the date of the observable 
price change, based on the per share price in Moderna's new round of financing.

On December 6, 2018, Moderna completed its initial public offering (IPO) and shares of Moderna began trading 
on the Nasdaq Global Select Market under the symbol “MRNA”. As part of the IPO, our preferred stock was converted 
into Moderna common stock and subject to a one year lock-up period. As our equity investment in Moderna common 
stock now has a readily determinable fair value, we are recording the investment at fair value, with the effects of the 
holding  period  restriction  estimated  using  an  option  pricing  valuation  model.  During  the  fourth  quarter  2018,  we 
recognized an unrealized loss of $56.4 in investment income to adjust our investment in Moderna to fair value as of 
December 31, 2018. 

The carrying value of this investment was $81.9 and $37.5 as of December 31, 2018 and 2017, respectively. 

Dicerna

In October 2018, we purchased $10.3 of Dicerna common stock in connection with a collaboration agreement 
that  we  entered  into  with  Dicerna,  a  publicly-traded  biopharmaceutical  company,  see  Note  11,  “Commitments  and 
Contingencies” for additional information on collaboration agreement. As our equity investment in Dicerna common 
stock has a readily determinable fair value, we are recording the investment at fair value. We have considered the effects 
of a six month holding period restriction and determined the impact on the fair value is immaterial. During the fourth 
quarter 2018, we recognized an unrealized loss of $1.4 in investment income to adjust our equity investment in Dicerna 
to fair value as of December 31, 2018.

The fair value of this investment was $8.9 as of December 31, 2018.

Debt

On June 7, 2018, we entered into an Amended and Restated Credit Agreement (the Credit Agreement), with Bank 
of America, N.A. as Administrative Agent. The Credit Agreement amends and restates our credit agreement dated as 
of June 22, 2015 (the Prior Credit Agreement). 

The  Credit  Agreement  provides  for  a  $1,000.0  revolving  credit  facility  and  a  $2,612.5  term  loan  facility.  The 
revolving credit facility and the term loan facility mature on June 7, 2023. Beginning with the quarter ending June 30, 
2019, we are required to make amortization payments of 5.00% of the aggregate principal amount of the term loan 
facility annually, payable in equal quarterly installments. 

Loans under the Credit Agreement bear interest, at our option, at either a base rate or a Eurodollar rate, in each 
case plus an applicable margin. Under the Credit Agreement, the applicable margins on base rate loans range from 
0.25% to 1.00% and the applicable margins on Eurodollar loans range from 1.25%to 2.00%, in each case based on 
our consolidated net leverage ratio (as calculated in accordance with the Credit Agreement). At December 31, 2018, 
the interest rate on our outstanding loans under the Credit Agreement was 3.90%. Our obligations under the Credit 
Agreement are guaranteed by certain of Alexion Pharmaceuticals, Inc.'s foreign and domestic subsidiaries and secured 
by liens on certain of our subsidiaries’ equity interests, subject to certain exceptions. Under the terms of the Credit 
Agreement, we must maintain a ratio of total net debt to EBITDA of 3.50 to 1.00 (subject to certain limited adjustments) 
and EBITDA to cash interest expense ratio of at least 3.50 to 1.00, in each case as calculated in accordance with the 
Credit Agreement.

The Credit Agreement contains certain representations and warranties, affirmative and negative covenants and 
events of default. The negative covenants in the Credit Agreement restrict Alexion’s and its subsidiaries’ ability, subject 
to certain baskets and exceptions, to (among other things) incur liens or indebtedness, make investments, enter into 
mergers and other fundamental changes, make dispositions or pay dividends. The restriction on dividend payments 
includes an exception that permits us to pay dividends and make other restricted payments regardless of dollar amount 
so long as, after giving pro forma effect thereto, we have a consolidated net leverage ratio, as defined in the Credit 
Agreement, within predefined ranges, subject to certain increases following designated material acquisitions. 

In connection with entering into the Credit Agreement and the Prior Credit Agreement, we paid an aggregate of
$53.1 in financing costs. Financing costs are amortized as interest expense over the life of the debt. Amortization 
expense associated with deferred financing costs for the years ended December 31, 2018, 2017, and 2016 was $8.0, 
$9.2,  and  $10.3,  respectively.  Remaining  unamortized  deferred  financing  costs  as  of  December 31,  2018  and 
December 31, 2017 were $20.8 and $21.0, respectively.

As of December 31, 2018, we had $2,612.5 outstanding on the term loan and $250.0 of borrowings outstanding 
under the revolving credit facility. The $250.0 of proceeds on the revolving credit facility was used to refinance amounts 
outstanding under the Prior Credit Agreement. As of December 31, 2018, we had open letters of credit of $1.7 that 
offset our availability in the revolving facility. In January 2019 we paid the outstanding revolving credit facility of $250.0
in full.

The fair value of our long term debt, which is measured using Level 2 inputs of the fair value hierarchy, approximates 

book value.

Facility Lease Obligations

New Haven Facility Lease Obligation

In November 2012, we entered into a lease agreement for office and laboratory space to be constructed in New 
Haven, Connecticut. The term of the lease commenced in 2015 and will expire in 2030, with a renewal option of ten
years. Although we do not legally own the premises, we are deemed to be the owner of the building due to the substantial 
improvements directly funded by us during the construction period based on applicable accounting guidance for build-
to-suit leases. Accordingly, the landlord’s costs of constructing the facility during the construction period are required 
to  be  capitalized,  as  a  non-cash  transaction,  offset  by  a  corresponding  facility  lease  obligation  in  our  consolidated 
balance sheets.

Construction of the facility was completed and the building was placed into service in the first quarter 2016. The 
imputed interest rate on this facility lease obligation as of December 31, 2018 was approximately 11%. Associated 
with this arrangement, we recognized interest expense of $13.3, $14.2, and $14.0 for the years ended December 31, 
2018, 2017, and 2016, respectively. As of December 31, 2018 and 2017, our total facility lease obligation was $133.5
and $134.6, respectively, recorded within other current liabilities and facility lease obligation in our consolidated balance 
sheets. 

In the fourth quarter of 2018 we amended the New Haven lease agreement significantly reducing our leased 
square footage in the building beginning in 2019 through the expiration of the lease. This amendment does not impact 
our previous conclusions that we are deemed the owner of the building for accounting purposes. In conjunction with 
this lease modification, during the fourth quarter of 2018 we made a payment of $53.0 to a third party as an incentive 
to lease the released square footage. This was capitalized within other assets in our consolidated balance sheets as 
of December 31, 2018.

Aggregate  future  minimum  non-cancellable  commitments  under  the  New  Haven  facility  lease  obligation,  as  of 

December 31, 2018 are as follows:

Lonza Facility Lease Obligation

During the third quarter 2015, we entered into a new agreement with Lonza Group AG and its affiliates (Lonza) 
whereby  Lonza  will  construct  a  new  manufacturing  facility  dedicated  to  Alexion  at  one  of  its  existing  facilities.  The 
agreement requires us to make certain payments during the construction of the new manufacturing facility and annual 
payments for ten years thereafter. As a result of our contractual right to full capacity of the new manufacturing facility, 
a portion of the payments under the agreement are considered to be lease payments and a portion as payment for the 
supply of inventory. Although we will not legally own the premises, we are deemed to be the owner of the manufacturing 
facility  during  the  construction  period  based  on  applicable  accounting  guidance  for  build-to-suit  leases  due  to  our 
involvement  during  the  construction  period.  Accordingly,  the  landlord’s  costs  of  constructing  the  facility  during  the 
construction period are required to be capitalized, as a non-cash transaction, offset by a corresponding facility lease 
obligation in our consolidated balance sheets. We expect the completion of the facility, including obtaining regulatory 
approval, to be in 2019. As of December 31, 2018 and 2017, we recorded a construction-in-process asset of $203.9
and $180.6, respectively, and an offsetting facility lease obligation of $155.1 and $159.1, respectively, within other 
current liabilities and facility lease obligation on our consolidated balance sheets.

Payments to Lonza under the agreement are allocated to the purchases of inventory and the repayment of the 
facility lease obligation on a relative fair value basis. In 2018, we incurred $73.8 of payments to Lonza under this 
agreement, of which $9.6 was applied against the outstanding facility lease obligation and $64.2 was recognized as a 
prepayment of inventory. See Note 11 “Commitments and Contingencies” for minimum fixed payments due under Lonza 
agreements.

Boston Facility Lease Obligation

In September 2017, we entered into a lease agreement for approximately 150,000 square feet of office space to 
be constructed in Boston, Massachusetts. Construction of the facility was completed and the building was placed into 
service in the second quarter 2018.  The term of the lease commenced upon the landlord's substantial completion of 
the facility in the second quarter of 2018 and will expire on the thirteenth anniversary of commencement, with an option 
to renew for up to an additional ten years. Although we do not legally own the premises, due to our involvement during 
the construction period, we are deemed to be the owner of the portion of the building that we will lease based on 
applicable  accounting  guidance  for  build-to-suit  leases.  Accordingly,  the  landlord's  costs  of  constructing  the  facility 
during  the  construction  period  were  capitalized,  as  a  non-cash  transaction,  offset  by  a  corresponding  facility  lease 
obligation in our consolidated balance sheets.

Interest expense recognized during 2018 was not material. As of December 31, 2018 and December 31, 2017, 
our total facility lease obligation was $83.6 and $59.6, respectively, recorded within facility lease obligation in our 
consolidated balance sheets.

Aggregate  future  minimum  non-cancellable  commitments  under  the  Boston  facility  lease  obligation,  as  of

Commitments and Contingencies

Commitments

License Agreements

We have entered into a number of license agreements in order to advance and obtain technologies and services 
related to our business. License agreements generally require us to pay an initial fee and certain agreements call for 
future payments upon the attainment of agreed upon development and/or commercial milestones. These agreements 
may also require minimum royalty payments based on sales of products developed from the applicable technologies, 
if any.

In October 2018, we entered into a collaboration agreement with Dicerna that provides us with exclusive worldwide 
licenses and development and commercial rights for two preclinical RNA interference (RNAi) subcutaneously delivered 
molecules for complement-mediated diseases, as well as an exclusive option for other preclinical RNAi molecules for 
two additional targets within the complement pathway. In addition to the collaboration agreement, we made an equity 
investment in Dicerna. Under the terms of the agreements, we made an upfront payment of $37.0 for the exclusive 
licenses and the equity investment. The market value of the equity investment was $10.3 as of the date of acquisition, 
which we recorded in other assets in our consolidated balance sheets. Due to the early stage of the assets we are 
licensing, we recorded the upfront license payment of $26.7 as research and development expense during the fourth 
quarter 2018. In addition, as of December 31, 2018, we could also be required to pay up to approximately $625.0 for 
option  exercise  fees  and  amounts  due  upon  the  achievement  of  specified  research,  development,  regulatory  and 
commercial milestones, as well as royalties on commercial sales. 

In December 2017, we entered into a collaboration and license agreement with Halozyme Therapeutics, Inc. that 
allows us to use drug-delivery technology in the development of subcutaneous formulations for our portfolio of products 
for up to four targets. Due to the early stage of the assets we are licensing, we recorded expense for the upfront payment 
of $40.0 during the fourth quarter 2017. In addition, as of December 31, 2018, we could be required to pay an additional

Notes to Consolidated Financial Statements
For the Years ended December 31, 2018, 2017 and 2016
(amounts in millions except per share amounts)

$160.0  for  each  target  developed,  subject  to  achievement  of  specified  development,  regulatory  and  sales-based 
milestones, as well as royalties on commercial sales.

In addition, as of December 31, 2018, we have entered into other license agreements under which we may be 

required to pay up to an additional $137.2 if certain development, regulatory and commercial milestones are met.

Manufacturing Agreements

We  have  various  manufacturing  development  and  license  agreements  to  support  our  clinical  and  commercial 

product needs. 

We rely on Lonza, a third party manufacturer, to produce a portion of commercial and clinical quantities of our 
commercial products and product candidates. We have various manufacturing and license agreements with Lonza, with 
remaining  total  non-cancellable  future  commitments  of  approximately  $1,084.6.  If  we  terminate  certain  supply 
agreements with Lonza without cause, we will be required to pay for product scheduled for manufacture under our 
arrangement. Under an existing arrangement with Lonza, we also pay Lonza a royalty on sales of SOLIRIS that was 
manufactured at the ARIMF facility prior to its sale and a payment with respect to sales of SOLIRIS manufactured at 
Lonza facilities.

In addition to Lonza, as of December 31, 2018, we have non-cancellable commitments of approximately $104.1

through 2020 with other third party manufacturers.

Contingent Liabilities

We are currently involved in various claims, lawsuits and legal proceedings. On a quarterly basis, we review the 
status  of  each  significant  matter  and  assess  its  potential  financial  exposure.  If  the  potential  loss  from  any  claim, 
asserted or unasserted, or legal proceeding is considered probable and the amount can be reasonably estimated, we 
accrue a liability for the estimated loss. Because of uncertainties related to claims and litigation, accruals are based 
on our best estimates based on information available at the time of the assessment. On a periodic basis, as additional 
information becomes available, or based on specific events such as the outcome of litigation or settlement of claims 
(and  offers  of  settlement),  we  may  reassess  the  potential  liability  related  to  these  matters  and  may  revise  these 
estimates, which could result in a material adverse adjustment to our operating results. Costs associated with our 
involvement in legal proceedings are expensed as incurred. The outcome of any such proceedings, regardless of the 
merits, is inherently uncertain. If we were unable to prevail in any such proceedings, our consolidated financial position, 
results of operations, and future cash flows may be materially impacted.

We have received, and may in the future receive, notices from third parties claiming that their patents may be 
infringed by the development, manufacture or sale of our products. Under the guidance of ASC 450, Contingencies, we 
record a royalty accrual based on our best estimate of the fair value percent of net sales of our products that we could 
be required to pay the owners of patents for technology used in the manufacture and sale of our products. A costly 
license, or inability to obtain a necessary license, could have a material adverse effect on our financial results.

In May 2015, we received a subpoena in connection with an investigation by the Enforcement Division of the SEC 
requesting information related to our grant-making activities and compliance with the FCPA in various countries. In 
addition, in October 2015, we received a request from the DOJ for the voluntary production of documents and other 
information pertaining to Alexion’s compliance with FCPA. The SEC and DOJ also seek information related to Alexion’s 
recalls of specific lots of SOLIRIS and related securities disclosures. Alexion is cooperating with these investigations. 

The investigations have focused on operations in various countries, including Brazil, Colombia, Japan, Russia and 

Turkey, and Alexion's compliance with the FCPA and other applicable laws. 

At this time, Alexion is unable to predict the duration, scope or outcome of these investigations. While it is possible 
that a loss related to these matters may be incurred, given the ongoing nature of these investigations, management 
cannot  reasonably  estimate  the  potential  magnitude  of  any  such  loss  or  range  of  loss,  or  the  cost  of  the  ongoing 
investigation. Any determination that our operations or activities are not or were not in compliance with existing laws 
or  regulations  could  result  in  the  imposition  of  fines,  civil  and  criminal  penalties,  equitable  remedies,  including 
disgorgement, injunctive relief, and/or other sanctions against us, and remediation of any such findings could have an 
adverse effect on our business operations. 

Alexion is committed to strengthening its compliance program and is currently implementing a comprehensive 
company-wide transformation plan to enhance and remediate its business processes, structures, controls, training, 
talent and systems across Alexion’s global operations.

As previously reported, on December 29, 2016, a shareholder filed a putative class action against the Company 
and certain former employees in the U.S. District Court for the District of Connecticut, alleging that defendants made 
misrepresentations and omissions about SOLIRIS. On April 12, 2017, the court appointed a lead plaintiff. On July 14, 
2017, the lead plaintiff filed an amended putative class action complaint against the Company and seven current or 
former employees. The complaint alleges that defendants made misrepresentations and omissions about SOLIRIS, 
including  alleged  misrepresentations  regarding  sales  practices,  management  changes,  and  related  investigations, 
between January 30, 2014 and May 26, 2017, and that the Company's stock price dropped upon the purported disclosure 
of the misrepresentations.  The plaintiffs seek to recover unspecified monetary relief, unspecified equitable and injunctive 
relief, interest, and attorneys’ fees and costs. Defendants moved to dismiss the amended complaint on September 
12, 2017. Plaintiffs filed an opposition to defendants’ motion to dismiss on November 13, 2017, and defendants’ filed 
a reply brief in further support of their motion on December 28, 2017.  Defendants’ motion to dismiss is now fully 
briefed and pending before the court. Given the early stages of this litigation, an estimate of the possible loss or range 
of loss cannot be made at this time.

In December 2016, we received a subpoena from the U.S. Attorney's Office for the District of Massachusetts 
requesting documents relating generally to our support of Patient Services, Inc. (PSI) and National Organization for Rare 
Disorders (NORD), 501(c)(3) organizations that provide financial assistance to Medicare patients taking drugs sold by 
Alexion; Alexion’s provision of free drug to Medicare patients; and Alexion compliance policies and training materials 
concerning the anti-kickback statute and information on donations to PSI and NORD from 2010 through 2016. Other 
companies have disclosed similar inquiries. We are cooperating with this inquiry. We have been engaged in discussions 
with the DOJ about a potential resolution of this matter and, in December 2018, we reached an agreement in principle 
to resolve this matter by entering into a civil settlement agreement with the DOJ and the Office of Inspector General 
(OIG)  of  the  U.S.  Department  of  Health  and  Human  Services.  As  part  of  the  proposed  resolution,  Alexion  will  pay 
approximately $13.0 to the DOJ and OIG.  While we have reached an agreement in principle, there can be no assurance 
that the steps necessary to conclusively resolve this matter will be successful or that the settlement terms will be 
finalized. We are unable to determine when a potential final settlement may be reached.  Further, if we are unable to 
reach a final agreement based on the agreement in principle, we will not be able to predict when these matters will be 
resolved or what further action, if any, the government will take in connection with them.  

In  May  2017,  Brazilian  authorities  seized  records  and  data  from  our  Sao  Paulo,  Brazil  offices  as  part  of  an 

investigation being conducted into Alexion’s Brazilian operations. We are cooperating with this inquiry.

In June 2017, we received a demand to inspect certain of our books and records pursuant to Section 220 of the 
General Corporation Law of the State of Delaware on behalf of a purported stockholder. Among other things, the demand 
sought to determine whether to institute a derivative lawsuit against certain of the Company’s directors and officers in 
relation to the investigation by our Audit and Finance Committee announced in November 2016 and the investigations 
instituted by the SEC, DOJ, U.S. Attorney’s  Office for the  District  of Massachusetts, and Brazilian law enforcement 
officials that are described above. We have responded to the demand. Given the early stages of this matter, an estimate 
of the possible loss or range of loss cannot be made at this time.

On September 27, 2017, a hearing panel of the Canadian Patented Medicine Prices Review Board (PMPRB) issued 
a decision in a previously pending administrative pricing matter that we had excessively priced SOLIRIS in a manner 
inconsistent with the Canadian pricing rules and guidelines. In its decision, the PMPRB ordered Alexion to decrease 
the price of SOLIRIS to an upper limit based upon pricing in certain other countries, and to forfeit excess revenues for 
the period between 2009 and 2017. The amount of excess revenues was not determined to be a material amount. In 
October 2017, Alexion filed an application for judicial review of the PMPRB’s decision in the Federal Court of Canada. 
The hearing of that application for judicial review took place on November 15 and 16, 2018 but a decision on this 
matter has not yet been delivered by the Court. At this time, we cannot predict the outcome of these judicial review 
proceedings or any appeals that may follow and cannot reasonably estimate the amount of any additional forfeitures 
that will be required to be made or the potential impact to future SOLIRIS revenues in Canada relating to any potential 
future price reduction.

In  October  2018,  the  Japanese  Ministry  of  Health,  Labour  and  Welfare  (MHLW)  conducted  an  administrative 
inspection of Alexion’s Japanese operations. The MHLW inquiry has been primarily focused on our communication efforts 
regarding the proper use of SOLIRIS in Japan for aHUS, among other matters. We have cooperated, and will continue 
to cooperate, with this inquiry. An estimate of the possible loss or range of loss, or what further action, if any, the MHLW 
will take in connection with this matter, cannot be made at this time.

Chugai Pharmaceutical Co., Ltd. has filed two lawsuits against Alexion.  The first was filed in November 2018 in 
the United States District Court for the District of Delaware against Alexion Pharmaceuticals, Inc. alleging that ULTOMIRIS 
infringes one U.S. patent held by Chugai Pharmaceutical Co., Ltd.  The second lawsuit was filed in December 2018 in 
the Tokyo District Court against Alexion Pharma GK (a wholly-owned subsidiary of Alexion) in Japan and alleges that 
ULTOMIRIS  infringes  two  Japanese  patents  held  by  Chugai  Pharmaceutical  Co.,  Ltd.  Chugai’s  complaints  seek 
unspecified  damages  and  certain  injunctive  relief.  Alexion  has  filed  an  answer  to  the  U.S.  complaint  that  denies 
infringement.   In  addition,  Alexion  has  raised  defenses  and  has  brought  several  counterclaims  against  Chugai 
Pharmaceutical Co., Ltd. that request a finding of non-infringement and patent invalidity. Alexion Pharma GK responded 
to Chugai at the Tokyo District Court and raised defenses against Chugai Pharmaceutical Co., Ltd. that request a finding 
of non-infringement and patent invalidity.  Given the early stages of these litigations, an estimate of the possible loss

In our reconciliation of our statutory U.S. federal income tax rate to our effective tax rate above, we have included 
a Benefit of foreign earnings amount which encapsulates the various tax impacts that result from our foreign derived 
income. As a result of U.S. Tax Reform, a substantial portion of our foreign earnings are subject to the GILTI minimum 
tax at an effective rate which is lower than the U.S. statutory tax rate of 21.0%.  While we are also subject to tax in 
foreign jurisdictions locally, substantially all of these taxes are creditable against U.S. taxes imposed on foreign earnings.  
As a result, the effective tax rate on our foreign earnings is lower than the U.S. statutory rate. 

In the year ended December 31, 2018, the Benefit of foreign earnings includes foreign local tax expense of $58.1, 
substantially all of which is offset by the benefit from U.S. foreign tax credits of $54.2, resulting in a net increase to 
the effective tax rate of 1.6%.  We incurred U.S. tax expense on our foreign earnings of $206.1, which includes GILTI 
minimum tax. The U.S. tax on our foreign earnings reflects a benefit of $108.7 or 44.8%, primarily related to the Section 
250(a) deduction, compared to the U.S. statutory rate. Also included in this component is a benefit of $67.7 from 
adjustments to 2018 provisional accounting for the Tax Act, which resulted in a decrease to our effective tax rate of 
approximately 28.0%.

In the year ended December 31, 2017, the Benefit of foreign earnings includes foreign local tax expense of $54.4 
partially offset by the benefit from U.S. foreign tax credits of $33.2, resulting in a net increase to the effective tax rate 
of 3.9%. We incurred transition tax imposed by the Tax Act of $177.9 and US deferred taxes related to the GILTI provisions 
of  the  Tax  Act  of  $165.4.  These  Tax  Act-related  adjustments  resulted  in  an  increase  to  our  effective  tax  rate  of 
approximately 62.7%.  Additional U.S. tax imposed on our foreign earnings of $171.7 reflects a benefit of $35.4 or 
6.5% compared to the U.S. statutory rate.

In the year ended December 31, 2016 the Benefit of foreign earnings includes foreign local tax expense of $42.8, 
more than offset by the benefit from U.S. foreign tax credits of $48.3, resulting in a net decrease to the effective tax 
rate of 0.9%.  Additional U.S. tax imposed on our foreign earnings of $103.9 reflects a benefit of $155.4 or 27.0%
compared  to  the  U.S.  statutory  rate.  Also  included  in  this  component  is  the  impact  to  deferred  tax  attributable  to 
distributions from our captive foreign partnership of $119.3, which increased the effective tax rate by 20.7%.

The effective tax rate reconciliation includes the tax impact of acquisitions of IPR&D assets. Absent successful 
clinical results and regulatory approval, there is no alternative use for certain acquired IPR&D assets. An increase to 
the effective tax rate results when the value of such assets are expensed, and no tax benefit is recognized. In the year 
ended December 31, 2018, this component of the effective tax rate includes an increase to tax expense of $248.4
related to the acquired IPR&D costs for the acquisitions of Wilson Therapeutics and Syntimmune, which increased our 
effective tax rate by 69.7% and 32.9%, respectively.

In the year ended December 31, 2018, Other permanent differences includes tax expense of $21.1 or 8.7% related 

to nondeductible compensation and tax benefit of $10.9 or 4.5% related to Foreign-Derived Intangible Income.

In 2017, we concluded the IRS examination of our 2013 and 2014 tax years. Conclusion of the IRS examination 

resulted in a decrease to the tax reserves component of the 2017 effective tax rate of approximately 3.6%.

The Tax Act

In December 2017, the Tax Cuts and Jobs Act (Tax Act) was enacted into law. The Tax Act decreased the US federal 
corporate tax rate to 21.0%, imposed a minimum tax on foreign earnings related to intangible assets (GILTI), a one-
time transition tax on previously unremitted foreign earnings, and modified the taxation of other income and expense 
items. With regard to the GILTI minimum tax, foreign earnings are reduced by the profit attributable to tangible assets 
and a deductible allowance of up to 50.0%, subject to annual limitations. We have elected to account for the impact 
of the minimum tax in deferred taxes. 

At December 31, 2017, the Tax Act resulted in an increase to tax expense and the effective tax rate of $45.8 and 

8.4%, respectively: 

(a) Income tax expense increased $177.9 or 32.5% related to the transition tax on unremitted earnings imposed 
by the Tax Act. This increase includes foreign income subject to US tax of $195.6, partially offset by a related 
benefit of foreign tax credits of $17.7. 

(b) The decrease to the U.S. federal tax rate resulted in a decrease to deferred tax expense of $292.4 or 53.4%. 
This decrease includes the $121.3 or 22.2% benefit of re-measuring domestic deferred taxes and an additional 
decrease attributable to re-measuring deferred taxes on foreign earnings of $171.1 or 31.2%.

(c) Other permanent differences includes a decrease to tax expense of $5.1 or 0.9% related to the re-measurement 

of income taxes payable as a result of changes in U.S. federal tax rates under the Tax Act.

(d) The enactment of the GILTI minimum tax increased US deferred taxes on foreign earnings $165.4 or 30.2%. 
This increase includes deferred tax expense related to the GILTI minimum tax of $236.9. This deferred expense 
is  partially  offset  by  a  related  decrease  to  deferred  expense  for  the  release  of  reserves  for  uncertain  tax 
positions of $71.5.

We calculated provisional amounts for the tax effects of the Tax Act that could be reasonably estimated, but not 
completed, in our results for the year ended December 31, 2017. As of the fourth quarter 2018 we had completed our 
analysis of all provisional estimates, and concluded as follows:

(a) We calculated a reasonable estimate of the one-time transition tax on previously unremitted earnings, which 
resulted in an increase to U.S. Federal tax expense of $177.9 and an increase to taxes payable, net of tax 
credits, of $28.0 in the period ended December 31, 2017. Our initial accounting for the transition tax was not

(amounts in millions except per share amounts)

complete as of December 31, 2017 because there was uncertainty regarding the calculation of the amounts 
subject to the tax. We completed our analysis of the transition tax and related interpretive guidance during the 
third quarter 2018. No significant measurement period adjustment to our initial accounting was required.

(b) We calculated a reasonable estimate of the impact of the GILTI minimum tax on deferred taxes, which resulted 
in an increase to U.S. Federal tax expense and the deferred tax liability of $236.9 in the period ended December 
31, 2017. Our initial accounting for the minimum tax was incomplete because there was uncertainty regarding 
the calculation of the temporary differences subject to the minimum tax. We completed our analyses of these 
temporary differences and the expected timing and manner of their reversal during the fourth quarter 2018. 
We recorded measurement period adjustments during 2018 which resulted in a decrease to U.S. federal tax 
expense of $67.7. 

(c) We calculated a reasonable estimate of the Tax Act’s limits on deductions for employee remuneration, including 
remuneration in kind, which resulted in an insignificant impact to tax expense, taxes payable, and deferred 
taxes in the period ended December 31, 2017. Our initial accounting for these limits was incomplete because 
there was uncertainty regarding the value of the deduction-limited remuneration. We completed our analysis 
of the relevant employee remuneration arrangements during the third quarter 2018. No measurement period 
adjustment to our initial accounting was required.

(d) We calculated a reasonable estimate of the impact of the Tax Act to U.S. state income taxes, which resulted 
in an increase to tax expense, taxes payable, and deferred taxes of $2.9, $2.2, and $0.7, respectively, in the 
period ended December 31, 2017. We interpreted the effect of the Tax Act's changes to federal law on each 
U.S. state's system of taxation as of the date of enactment. We completed additional analysis of the effect of 
modifications to federal deductions and income inclusions on U.S. state tax systems in the fourth quarter 
2018. No measurement period adjustment to our initial accounting was required.

(e) We calculated the deferred tax liability related to our foreign captive partnership in the period ended December 
31, 2017 consistent with our calculation in periods prior to enactment of the Tax Act. As a result, the deferred 
tax liability we recorded as of December 31, 2017 of $533.4 related to our foreign captive partnership was 
provisional.  We completed additional analysis of the direct and indirect effects of the Tax Act during the fourth 
quarter 2018. We recorded measurement period adjustments during 2018 which resulted in an increase to 
U.S. state income tax expense and deferred taxes of $11.1.

Deferred Taxes

Provisions have been made for deferred taxes based on the differences between the basis of the assets and 
liabilities for financial statement purposes and the basis of the assets and liabilities for tax purposes using currently 
enacted tax rates and regulations that will be in effect when the differences are expected to be recovered or settled. The 
components of the deferred tax assets and liabilities are as follows:

At December 31, 2018, we have tax effected federal and state net operating loss carryforwards of $20.0 and 
$11.6, respectively. Our net operating losses expire between 2022 and 2038. We also have federal and state income 
tax credit carryforwards of $370.6 and $8.4, respectively. These income tax credits expire between 2025 and 2038. 

The increase in our net operating losses is due to the acquisition of Syntimmune and the recognition of historical 
net operating loss carryforwards which are subject to annual utilization limitations in accordance with Section 382 of 
the Internal Revenue Code. The decrease in income tax credits is attributable to the utilization of Orphan Drug credits. 
The decrease in our investment in foreign partnership deferred tax liability is due to adjustments we recorded in 2018 
to our provisional accounting for the Tax Act and the reversal of other component temporary differences. We continue 
to maintain a valuation allowance against certain deferred tax assets where realization is not certain. 

Included  in  our  investment  in  foreign  partnership  above  is  $(24.1)  associated  with  GILTI  minimum  tax.    Our 
accounting for the GILTI minimum tax on our captive foreign partnership as a result of the Tax Act was provisional at 
December 31, 2017. We completed our accounting for the Tax Act in the fourth quarter 2018.

Unrecognized Tax Benefits

We  follow  authoritative  guidance  regarding  accounting  for  uncertainty  in  income  taxes,  which  prescribes  a 
recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax 
position taken or expected to be taken in a tax return. The interpretation also provides guidance on derecognition, 
classification, interest and penalties, accounting in interim periods, disclosures, and transition.

The total amount of accrued interest and penalties was not significant as of December 31, 2018. The total amount 
of tax benefit recorded during 2018, 2017, and 2016 which related to unrecognized tax benefits was $35.4, $27.1, 
and $21.5, respectively. All of our unrecognized tax benefits, if recognized, would have a favorable impact on the effective 
tax rate.

It  is  reasonably  possible  that  a  portion  of  our  unrecognized  tax  benefits  could  reverse  within  the  next  twelve 
months. Reversal of these amounts is contingent upon the completion of field audits by the taxing authorities in several 
jurisdictions, whether a tax adjustment is proposed, the nature and amount of any adjustment, and the administrative 
path to resolving the proposed adjustment. We cannot reasonably estimate the range of the potential change.

Tax Audits

We file federal and state income tax returns in the U.S. and in numerous foreign jurisdictions. The U.S. and 
foreign jurisdictions have statutes of limitations ranging from 3 to 6 years. However, the limitation period could be 
extended due to our tax attribute carryforward position in a number of our jurisdictions. The tax authorities generally 
have the ability to review income tax returns for periods where the limitation period has previously expired and can 
subsequently adjust tax attribute values. 

In 2017, the IRS commenced an examination of our U.S. income tax returns for 2015. We anticipate this audit 
will conclude within the next twelve months. We have not been notified of any significant adjustments proposed by the 
IRS. 

Undistributed Earnings

We have recorded tax on the undistributed earnings of our controlled foreign corporation (CFC) subsidiaries. To 
the extent CFC earnings may not be repatriated to the U.S. as a dividend distribution due to limitations imposed by law, 
we have not recorded the related potential withholding, foreign local, and U.S. state income taxes.

Share-based Compensation

2017 Incentive Plan

The 2017 Plan was approved by our stockholders in May 2017 and replaced the 2004 Plan effective May 10, 
2017. The 2017 Plan is a broad based plan that provides for the grant of equity awards including restricted stock and 
restricted stock units (collectively referred to as Restricted Stock), incentive and non-qualified stock options, and other 
stock-related awards to our directors, officers, key employees and consultants, for up to a maximum of 18.2 shares in 
addition  to  awards  outstanding  under  the  2004  Incentive  Plan  on  or  after  March  14,  2017  that  are  subsequently 
canceled, cash settled, expired, forfeited, or otherwise terminated without the delivery of such shares, subject to the 
limitations in the 2017 Plan. Stock options granted under the 2017 Plan have a maximum contractual term of ten years 
from the date of grant, have an exercise price not less than the fair value of the stock on the grant date and generally 
vest over four years. Restricted Stock awards also generally vest over four years, with performance-based restricted 
stock units having a three-year vesting period.

Total intrinsic value of stock options exercised during the years ended December 31, 2018, 2017 and 2016 was 
$27.5, $88.9 and $41.7, respectively. We primarily utilize newly issued shares to satisfy the exercise of stock options. 
The total fair value of options vested during the years ended December 31, 2018, 2017 and 2016 was $27.2, $61.5
and $58.1, respectively.

We did not grant any stock options during the year ended December 31, 2018. For the years ended December 31, 
2017 and 2016, the fair value of options at the date of grant was estimated using the Black-Scholes model with the 
following ranges of weighted average assumptions: 

Expected life in years

Interest rate

The expected stock price volatility rates are based on historical volatilities of our common stock. The risk-free 
interest rates are based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with 
the expected life of the option. The average expected life represents the weighted average period of time that options 
granted are expected to be outstanding. We have evaluated three distinct employee groups in determining the expected 
life  assumptions,  and  we  estimate  the  expected  life  of  stock  options  based  on  historical  experience  of  exercises, 
cancellations and forfeitures of our stock options.

The weighted average fair value at the date of grant for options granted during the years ended December 31, 

2017 and 2016 was $42.59 and $41.46 per option, respectively.

The fair value of Restricted Stock at the date of grant is based on the fair market value of the shares of common 
stock underlying the awards on the date of grant. The weighted average fair value at the date of grant for Restricted 
Stock awards granted during the years ended December 31, 2018, 2017 and 2016, including restricted stock units 
with  performance  conditions,  was  $119.27,  $125.39  and  $133.35  per  share,  respectively.  The  total  fair  value  of 
Restricted Stock vested during the years ended December 31, 2018, 2017 and 2016 was $181.7, $157.0 and $124.4, 
respectively.

Included in the table above is 0.3 shares granted to senior management with market-based performance conditions 
which provide the recipient the right to receive restricted stock at the end of a three year performance period, based 
on pre-established market-based performance goals. We used payout simulation models to estimate the grant date fair 
value of these awards  at $123.25. Expense  recognized for awards  with market-based performance conditions was 
$14.9 for the year ended December 31, 2018 and immaterial for the years ended December 31, 2017 and 2016.

Employee Stock Purchase Plan

During 2015, the Company adopted the ESPP under which employees can purchase shares of our common stock 
based on a percentage of their compensation subject to certain limits. The purchase price per share is equal to the 
lower of 85.0% of the fair market value of our common stock on the offering date or the purchase date with a six month 
look-back feature. Under the ESPP, up to 1.0 shares of common stock may be issued to eligible employees who elect 
to participate in the purchase plan. Shares issued and compensation expense recognized under the ESPP for the years 
ended December 31, 2018, 2017 and 2016 were not material.

Stockholders’ Equity

Share Repurchases

In November 2012, our Board of Directors authorized a share repurchase program. The repurchase program does 
not have an expiration date, and we are not obligated to acquire a particular number of shares. The repurchase program 
may be discontinued at any time at the Company’s discretion. In February 2017, our Board of Directors increased the 
amount  that  we  are  authorized  to  expend  on  future  repurchases  to  $1,000  under  the  repurchase  program,  which 
superseded all prior repurchase programs. The repurchase program does not have an expiration date. The repurchase 
program may be discontinued at any time at our discretion. Under the program, we repurchased 0.7 and 4.0 shares of 
our common stock at a cost of $85.0 and $463.6 during the years ended December 31, 2018 and 2017, respectively. 

As of February 6, 2019, there is a total of $451.5 remaining for repurchases under the repurchase program.

Fair Value Measurement

Authoritative  guidance  establishes  a  valuation  hierarchy  for  disclosure  of  the  inputs  to  the  valuation  used  to 
measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows. Level 1 inputs are quoted 
prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar 
assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly 
through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable 
inputs based on our own assumptions used to measure assets and liabilities at fair value.

The following tables present information about our assets and liabilities that are measured at fair value on a 
recurring basis as of December 31, 2018 and 2017, and indicate the fair value hierarchy of the valuation techniques 
we utilized to determine such fair value.

Valuation Techniques

We classify mutual fund investments and equity securities, which are valued based on quoted market prices in 

active markets with no valuation adjustment, as Level 1 assets within the fair value hierarchy. 

Cash  equivalents  and  marketable  securities  classified  as  Level  2  within  the  valuation  hierarchy  consist  of 
commercial paper, reverse repurchase agreements, U.S. and foreign government-related debt, corporate debt securities 
and certificates of deposit. We estimate the fair values of these marketable securities by taking into consideration 
valuations obtained from third-party pricing sources. These pricing sources utilize industry standard valuation models, 
including both income and market-based approaches, for which all significant inputs are observable, either directly or 
indirectly, to estimate fair value. These inputs include market pricing based on real-time trade data for similar securities, 
issuer credit spreads, benchmark yields, and other observable inputs. We validate the prices provided by our third-party 
pricing sources by understanding the models used, obtaining market values from other pricing sources and analyzing 
pricing data in certain instances.

Other investments in equity securities of publicly traded companies which are subject to holding period restrictions 
are carried at fair value using an option pricing valuation model and classified as Level 2 equity securities within the 
fair value hierarchy. The most significant assumptions within the option pricing valuation model are the term of the 
restrictions and the stock price volatility, which is based upon the historical volatility of similar companies. We also use 
a constant maturity risk-free interest rate to match the remaining term of the restrictions on such investments.

Our derivative assets and liabilities include foreign exchange and interest rate derivatives that are measured at 
fair  value  using  observable  market  inputs  such  as  forward  rates,  interest  rates,  our  own  credit  risk  as  well  as  an

(amounts in millions except per share amounts)

evaluation of our counterparties’ credit risks. Based on these inputs, the derivative assets and liabilities are classified 
within Level 2 of the valuation hierarchy.

Contingent consideration liabilities related to acquisitions are classified as Level 3 within the valuation hierarchy 
and are valued based on various estimates, including probability of success, discount rates and amount of time until 
the conditions of the milestone payments are met.

As of December 31, 2018, there has not been any impact to the fair value of our derivative liabilities due to our 
own credit risk. Similarly, there has not been any significant adverse impact to our derivative assets based on our 
evaluation of our counterparties’ credit risks.

Contingent Consideration

In connection with prior business combinations, we may be required to pay future consideration that is contingent 
upon the achievement of specified development, regulatory approvals or sales-based milestone events. We determine 
the fair value of these obligations using various estimates that are not observable in the market and represent a Level 
3 measurement within the fair value hierarchy. The resulting probability-weighted cash flows were discounted using a 
cost of debt ranging from 4.2% to 5.1% for developmental milestones and a weighted average cost of capital ranging 
from 9.0% to 21.0% for sales-based milestones.

Each reporting period, we adjust the contingent consideration to fair value with changes in fair value recognized 
in operating earnings. Changes in fair values reflect new information about the probability and timing of meeting the 
conditions of the milestone payments. In the absence of new information, changes in fair value will only reflect the 
interest component of contingent consideration related to the passage of time. 

As of December 31, 2018, estimated future contingent milestone payments related to prior business combinations 
range from zero if no milestone events are achieved, to a maximum of $702.0 if all development, regulatory and sales-
based milestones are reached. As of December 31, 2018, the fair value of acquisition-related contingent consideration 
was $280.8. The following table represents a roll-forward of our acquisition-related contingent consideration:

In September 2018, we sold all our assets, rights and obligations related to the ALXN1101 program to a third 
party and, as a result, in the quarter ended September 30, 2018, derecognized $4.6 of contingent consideration due 
under our prior purchase agreement with Orphatec Pharmaceuticals GmbH, dated February 8, 2011. The definitive 
agreement  related  to  our  sale  of  ALXN1101  provides  for  contingent  consideration  payments  to  Alexion  upon  the 
achievement of various regulatory and commercial milestones and other events, as well as royalties on commercial 
sales. The amount of contingent consideration related to these contingent payments is deemed to be fully constrained 
as of December 31, 2018, and therefore has not been included in the transaction price. During the third quarter 2018, 
we recognized an immaterial gain on the sale of ALXN1101 within operating income.

In September 2018, we amended the terms of certain contingent milestone payments due under our prior merger 
agreement with Enobia Pharma Corp., dated December 28, 2011.  The agreement removed our obligations with respect 
to a regulatory milestone and redistributed the contingent payment associated with this milestone to various sales 
milestones.  As a result of this agreement and the probability of achieving the various sales milestones, our contingent 
consideration liability increased by $48.7 in the third quarter 2018.

Employee Benefit Plans

Deferred Compensation Plan

We have a nonqualified deferred compensation plan which allows certain highly-compensated employees to make 
voluntary deferrals of up to 80% of their base salary and incentive bonuses. The plan is designed to work in conjunction 
with the 401(k) plan and provides for a total combined employer match of up to 6% of an employee’s eligible earnings, 

F-48

Alexion Pharmaceuticals, Inc. 

Notes to Consolidated Financial Statements
For the Years ended December 31, 2018, 2017 and 2016
(amounts in millions except per share amounts)

up to the IRS annual 401(k) contribution limitations. Deferred compensation amounts under this plan as of December 31, 
2018 and 2017 were $16.5 and $18.5, respectively, and are included in other liabilities within the consolidated balance 
sheets. Employer matching contributions under the plan for the years ended December 31, 2018, 2017 and 2016 were 
not material.

Defined Contribution Plan

We have one qualified 401(k) plan covering all eligible employees. Under the plan, employees may contribute up 
to the statutory allowable amount for any calendar year. We make matching contributions equal to $1.00 for each dollar 
contributed up to the first 6% of an individual’s base salary and incentive cash bonus up to the annual IRS maximum. 
For the years ended December 31, 2018, 2017 and 2016, we recorded matching contributions of approximately $14.1, 
$15.9, and $16.7 respectively.

Defined Benefit Plans

We maintain defined benefit plans for employees in certain countries outside the U.S., including retirement benefit 
plans required by applicable local law. The plans are valued by independent actuaries using the projected unit credit 
method. The liabilities correspond to the projected benefit obligations of which the discounted net present value is 
calculated based on years of employment, expected salary increases, and pension adjustments.

In 2018 and 2017 we recorded the impacts of a curtailment related to our Swiss plan as a result of a reduction 

of employees due to restructuring events as discussed in Note 18, “Restructuring and Related Expenses”.

The following table sets forth the funded status and the amounts recognized for defined benefit plans, including 

the impacts of the curtailments:

The Company measures the fair value of plan assets based on the prices that would be received to sell an asset 
or paid to transfer a liability in an orderly transaction between market participants at the measurement date. All plan 
asset investments are classified as Level 2 within the fair value hierarchy and are valued utilizing observable prices for 
similar instruments and quoted prices for identical or similar instruments in markets that are not active. Plan assets 
are managed by an independent investment fiduciary and are primarily invested in debt and equity securities and real 
estate funds in order to maximize the overall return from investment income considering asset allocation limits as 
determined by pension law.

At December 31, 2018, we have recorded a liability of $17.6 in other noncurrent liabilities and an additional 

minimum liability of $2.6,  net of tax, to accumulated other comprehensive income.

The following table provides the weighted average assumptions used to calculate net periodic benefit cost and 

the actuarial present value of projected benefit obligations:

The discount rates used to determine the net periodic benefit cost and projected benefit obligation represent the 

yield on high quality AA-rated corporate bonds for periods that match the duration of the benefit obligations.

The expected long-term rate of return on plan assets represents a weighted average of expected returns per asset 
category. The rate of return considers historical and estimated future risk free rates of return as well as risk premiums 
for the relevant investment categories.

Restructuring and Related Expenses

In the first quarter of 2017, we initiated a company-wide restructuring designed to help position the Company for 
sustainable, long-term growth that we believe will further allow us to fulfill our mission of serving patients and families 
with rare diseases. The initial restructuring activities primarily focused on a reduction of the Company's global workforce. 
In September 2017, we committed to an operational plan to re-align the global organization with its refocused corporate 
strategy. The re-alignment focuses investments in priority growth areas to maximize leadership in complement and grow 
the rare disease business. The re-alignment also included the relocation of the Company's headquarters to Boston, 
Massachusetts which was completed in the second quarter of 2018. Our New Haven, Connecticut site continues to 
support employees working in the research and process development laboratories, the clinical supply and quality teams, 
nurse case management and a number of important enterprise business services. The plan also reduced the Company's 
global  workforce  by  approximately 20.0%.  The  restructuring  is  designed  to  result  in  cost  savings  by  focusing  the 
development portfolio, simplifying business structures and processes across the Company's global operations, and 
closing of multiple Alexion sites, including ARIMF and certain regional and country-based offices.

Employee separation costs are associated with headcount reductions, as well as corporate employees not relocating 

to the Company's headquarters in 2018.

Asset-related  charges  consist  of  accelerated  depreciation  costs  and  asset  impairment  charges.  Accelerated 
depreciation costs primarily relates to site closures, including ARIMF (which was sold to a third-party in 2018). Accelerated 
depreciation costs represent the difference between the depreciation expense recognized over the revised useful life 
of the asset, based upon the anticipated date the site closure and the depreciation expense as determined using the 
useful life prior to the restructuring activities. Asset impairment charges primarily related to manufacturing assets that 
will no longer be utilized due to the 2017 restructuring activities.

Other costs consist of contract termination expenses, relocation costs, and other costs incurred as a direct result 

of an exit plan.

The following table presents a reconciliation of the restructuring reserve recorded within accounts payable and 
accrued expenses on the Company's consolidated balance sheets for the years ended December 31, 2018 and 2017:

The  restructuring  reserve  of  $4.2  and  $58.2  is  recorded  in  accounts  payable  and  accrued  expenses  on  the 

Company's consolidated balance sheet as of December 31, 2018 and 2017, respectively. 

As a result of the relocation of our corporate headquarters to Boston, Massachusetts, we were required to repay 
a  forgivable  loan  and  grant  that  were  provided  by  the  State  of  Connecticut  Department  of  Economic  Community 
Development in 2015 in connection with the construction of our current headquarters in New Haven, Connecticut. The 
loan and grant totaled $26.0 and were recognized, upon receipt, as a reduction in the cost of our New Haven facility-
related fixed assets. As a result, the $26.0 repayment obligation was recorded in the third quarter 2017 with an offsetting 
increase in the carrying value of the related assets. We repaid this amount in the fourth quarter 2017.

In the first quarter 2019, we have undertaken corporate restructuring activities to re-align our global 
organization with our re-focused strategy, reduce costs, and realize operational efficiencies.  We expect to incur 
estimated expenses up to $25.0 associated with this recent restructuring by the end of 2019.

Subsequent Events

In January 2019, we entered into a collaboration agreement with Caelum Biosciences (Caelum) to develop 
CAEL101 for light chain (AL) amyloidosis.  Under the terms of the agreement, we acquired a minority equity interest 
in Caelum and an exclusive option to acquire the remaining equity in the company based on Phase 2 data, for pre-
negotiated economics.  We made an upfront payment of $30.0 and could be required to pay up to an additional 
$30.0 in contingent milestone-dependent option fees. The collaboration also provides for potential additional 
payments, in the event Alexion exercises the acquisition option, for up to $500.0, which includes an upfront option 
exercise payment and potential regulatory and commercial milestone payments.
